Air pulse vibrator invented by EIS under brand satisfyer is giving huge satisfaction to the users.

"When stimulating the right places, I feel like upsoaring into heaven." a Amazon buyer wrote her review like that. A small nozzle makes her “laid” or even “paralytic”, this Air-Pleasure toy (also called “air-pulse toy") magically bring a selling summit, although its design concept origins “blow job”, the air flow generated from its internal motor operating overwhelmingly spur clits to bounce what satisfies women than self-labor work.

Normally air-pleasure toys 5-10 modes to freely chose depending on your endurance, low-level mode imitates “whisper” to incite clitoris itch, meanwhile its vibration promotes personal sex experience. Deeper uterus internal sensations varied to the different levels, intensity level and powerful suction usually quicker to orgasm state with more intimate feeling.

Plus its waterproof silicone material, some people tend to use this sex toy when taking bath, totally relieved. From the point of view that clits suction fills empty part of personal safety, babies are born out of the womb with instinct that “warm home” is inside ladies' belly.

Adapt to different size of clits is also another advantage, intermittent flow-in through its mouthpiece slightly bigger and broader the clits, some air-pulse toys are sold with additional nozzle that are detachable, it always excites your never.

Let's see how the magic is created.

Many people think that air pulse is suction, but it is not. Suction a continuous negative pressure created by pump. Such continuous negative pressure will make the human body very uncomfortable in our test.
Air pulse is air vortex, the following video made detailed scientific explanation:

EIS introduced air vortex into vibrator and applied for global patent in 2016, which built consolidated barriers to entry for them.

Let's take a look what patent documentation says about how it works:
As shown in the figure below, the pressure field generating device (10) has at least one cavity (12), the cavity has a first end (12a) and a second end (12b), and the second end is opposite to the first end (12a) and away from the first end (12a), wherein the first end (12a) has at least one opening (8) to be placed on the body part; and the driving device (20, 22) ), the driving device is configured to cause the volume of cavity (12) to change between the maximum and the minimum , so that an stimulating pressure field is generated in the opening (8).

Our engineering team is from car industry with strong competence in mechanical engineering, who was very confident to invent a new device to bypass EIS patent. Here below is one of our preliminary technical proposal:

However, after discussions with the patent service provider, this solution was finally abandoned, because although the driving method is different, it is still within the scope of EIS patent protection. The core of this patent is that the cavity volume changes between the maximum and the minimum, which can never be bypassed. EIS good job:)

As a leading design house of sex toy, we are continuously trying to bring new technology like pressure senor, air pump into product to have new experience. Several products with new concepts are under development, welcome to contact us to explore new future.
