How a piezoelectric gas lighter works 

the gas lighter just convinces you it works

This is one of the MOST underrated channels on RU-vid. You Guys deserve FAR MORE subscribers. But, you WILL Get there, slowly but surely. These animations are critical not only for ALL engineering students but also for anyone interested in everyday technology.

It's amazing how all of these come together are sold for 1-2USD each, thanks to engineering for mass production. It's cheaper than match.

The fact youre doing this all by hand is crazy. You got my sub

Thank you for clear explanation of how a piezoelectric gas lighter works

Love your simple, concise, and highly instructional videos.

only 2 guys are behind these videos? neat. keep up the good work! very well done

Love how you guys deconstruct common items and open a window into the amazing engineering that makes even the simplest aspects of our daily lives possible. You guys rock!

I guessed 7. Than thought you'd tricked us with only 3. Than double played us with the 4th 5th and 6th. Cool to see how many moving parts even simple seeming things can have. Incredible quality animations with unlimited potential this channel.

This channel is now my second favorite when it comes to educational animated videos. The first being Jared Owen Animations.

I've been opening lighters since I was a kid. I started with a lighter that uses spark from a rod and a grooved cylinder. Those only have 3 springs. Crickets lighter are often non-refillable. I always refill my lighters too until the piezoelectric ignition stops working or any parts are not working properly. But I still keep them so that when my new lighter has problems, I can salvage parts from the old one.

Top notch CAD modeling

Much more interesting from the inside than it seems from the outside! I store my gas lighters in the freezer at minus 18 degrees Celsius when I don't need them so they don't lose gas. I also put lighters in the refrigerator before refilling so that the pressure in the tank is lower than in the refill cartridge and the gas is refilled quickly and without much loss.

I love seeing how far just mechanical pieces can get us, without even using software at any point

My guess was 5. Literally not even an hour ago my spouse had to refill a butane torch, which I assume works much like this only with the ability to get to higher temps. You two are a great channel for information and I do not care how long you take as long as the videos keep being informative and interesting.

I’ve ALWAYS had trouble with many lighters similar to this in particular around refilling time to realise, thanks to your brilliant video, that the “rest period for the fresh gas injection” might have had a lot to do with it! I thank you Sir! 👍👍👍

Goldeneye pause music works great to the intro of the lighter spinning

BRILLIANT EXPLANATION, ON POINT!

You are changing my live with your videos. Thank you

i guessed 5 and I hope that you guys continue this content thank you so much for satisfying our engineer curiosity ❤

Guessed correctly. And learned why I need to wait after filling!

This would be alien magic to a medieval peasant.

daym. didn't knew a lighter was this complicated.

I would have guessed 3 before seeing the video, maybe 4 at the most. I then guessed 5 after you showed the deconstructed cross section.

Amazing production of the whole video.😊Continue it 👏

Amazing work! Thank you!

I use the empty lighters to start my grill. I do not know how old it is but it still starts it up. I took apart one where it was just a regular lighter built in with extensions.

This is great!

That is such a cool thing that how quartz crystals could be positive and negative and make a charge like that when you smack them together super cool man

Would be very interesting to see how a pneumatic impact wrench works.

thanks to your superb video, i'm smarter, it's an ingenious invention and your overview is great.

Thank you for this video !

It's nice being able to put a face to the great content, two in fact! :)

Usually, they don't. At least two of three are bad out of the box, the one that works typically takes a lot of force to activate the piezoelectric device. You then get a flame, if the gas hasn't leaked out since it left the factory in China.

It takes a lot to make such animations !

Love your channel. Always share your videos.

Really like your channel, have shared it with others

6 springs

Thank you very much for the videos

I get excited when I see you've got a new video out. Appreciate your work!

Brilliant animation and explanations, as always. We learn more with such a well-made short video than with hours or reading a book. Total respect to you both, keep up the great work !

Love the video

Great job!

Love this channel. ❤

amazing work keep going 💪

I LOVE your videos!

was waiting for this

Great video, we need more creators like you guys to make us a little more informed about the world around us.

Awesome

Maybe a bit more detail on how piezoelectric materials work? Nice work, anyhow.

Great videos!

Cool!

I feel like the swaying back and forth at the beginning was a bit too much. I don't know if ot was that the lighter occupied too much horizontal space in the frame, and so it felt crammed, or if it was the focal length making the tip of the lighter move too much as it passed by and hard for the eye to follow, or maybe the frequency and speed of going from one side to the other was too much and it felt restless. Anyway, nice to meet y'all, fantastic work as always

very cool keep it up

Good

I want to say that the construction of the safety button is uncommon, atleast here in sweden, never seen that construction with a "disabling" trigger that still can be depressed (but doesn't work) in locked mode. Maybe there is different standards in different countries, but on our gas lighters here in sweden the safety lock button instead physically locks the trigger completely, it cannot be depressed at all without pressing the safety button. Theres 2 variants, one that is based on a catch on the safety button, engaging a hole in the trigger. Then the safety button is located ABOVE the trigger, between the gas outlet and the trigger. Other variants have a slot in the trigger, where the safety button has a rod with a thicker portion (that does not allow the slot to pass), and then a thinner portion (that does allow the slot to pass), depressing the safety button aligns the thinner portion with the slot, allowing the trigger to be depressed. These types have the safety button located BELOW the trigger, between the gas canister and the trigger. Then there is the variants with the slider, which is a toggle switch, located below the trigger on the side. Then its just a L shaped hole in the trigger, and a pin on the safety lock switch which rides in the L-shaped hole, You can propably imagine how that works, when the trigger isn't depressed, the unlocked safety button pin is in the corner of the L. when the safety button is moved to the locked position, the pin moves horizontally in the L, and then the trigger can't just physically move. When trigger is in unlocked position and trigger is depressed, pin of safety button is moved along the vertical slot of L.

I guessed 4 springs 😒. Nice work guys always enjoy your videos!

My guess was 3. And dang. To think there's so many springs in this.

guessed 6. I saw 4 springs at first, realized there's 2 valves, and the thing behind the trigger looked like it had 2 springs so all in all 2 springs in the butane release thing, 2 valve springs, then 2 springs for the piezoelectric thing

I love your chanel

I love this cahnnel

While the refill valve *is* often used to add fuel to the lighter, we can't forget its other, arguably more common use: accidentally getting butane all over the place and making the entire place smell like gas

I guessed about six, but then decided to guess a higher number to account for ones I overlooked and came out at eight. You saying there'd be more than we'd think was probably involved in that.

55…This isn’t a guess, just a nonsense comment. New sub

So only the “safety” button engages the butane valve, and the main button can still depress the piezo hammer = you would have a choice of spark or flame with that particular design 🙂

i only guessed 4 springs! forgot the refill valve and the 2nd spring in the igniter!

4:00 But presumably the safety lock mechanism has no effect on the spark generator so it could still be used to ignite an oven's gas burners?

How many people actually bother to refill. I can never get the 2 parts to mate correctly so gas goes everywhere.

My only idea is that some of the motion might be better illustrated in 3/4 view, not just pure planar view. Also, yes, the piezoelectric material is good for tens of thousands of strikes, but the plastic components in a sub-$1 lighter are not. In 50 years I've only had two last long enough to be worth refilling. (I'm well aware I'm buying cheap quality lighters.)

I’ve never refilled one of these things.

Topmoumoute ;)

My guess for the springs- 9 Edit: guess I was wrong.

👍👍

❤

TOP LIKE 🙏🏼🇧🇷🙏🏼 🇧🇷👍🇧🇷

0:51 Seven springs I guess

❤❤❤❤

👍

Just drop your comment here to help the channel 😁

I swear, just yesterday I tried to fix one to no avail

Only six springs?

I guess it's 5 springs.

I said seven springs! So close😢.

How do the crystals recharge themselfs after each use?

hello

6.

how Turkey automatic OK table work ?

I have a lighter like that in Germany. The rattle will be blocked if you don't push in the child safety lock.

0:49 - 5

10

6

392 springs

cant you just remove the spring to the safety lock

9

I guessed 5 springs you said 6 Bah I am wrong. :(

I guessed 5, oof

The first syllable of piezoelectric is said like "pee", not "pie". Some folks say "pee-ayy-zoh". In no case is it "pie-zoh".

i thought it is a Canny video.

pronounced in American not english Its ......PEE- A -ZO...... not PIE ZO...... this really got me other then that love the video.

4:41 isn’t that dangerous? Don’t transmission power lines use high voltage and low current? What would happen to you if you perform a 1000 degree knife challenge on the lighter and you slice through that wire? Seems quite sus to me man. There should be some regulations on the design.
