Description

[Detailed Description of the Invention] This invention relates to a suction tool that utilizes the pressure of pressurized air generated by a compressor for suction.

One of the devices for facial massage uses the power of inhalation, but many of the devices that mechanically generate the inhalation power are large-scale and inevitably lead to high costs.

This idea was devised in view of the fact that the mechanism for mechanically generating intake force would be large-scale, and focused on the fact that such uneconomical issues could be resolved by using pressurizing force. An embodiment of this invention will be explained based on the drawings.

will be established.

37 is a suction attachment detachably attached to the outer periphery of the boss 34, and has an intake chamber 38 on the front part.
A flow hole 39 communicating with the boss 34 is provided at the center of the bottom of the boss 34, and when the attachment 37 is pressed against the face and air flows inside the boss 34 in the direction of the arrow in FIG. 2, negative pressure is created in the intake chamber 38. is starting to occur.

40 is the rib 35 provided on the back surface of the attachment 37.
The filter 41 is held between the ribs 35 and 40 which are paired with the ribs 35 and 40.

Next, the operation of the above embodiment will be explained.

Air pressurized by a compressor (not shown) is
It reaches the supply cylinder 4, the small hole 5, the annular passage 10, and the valve port 6 via the hose 43.

At this time, if the valve body 27 is in the state shown in FIG. It is discharged outside (Figure 1).

Therefore, the air pressure inside the annular portion 10 does not increase, the piston 25 maintains its advanced state due to the elastic force of the compression spring 24, and the rod 26 integrated with the piston 25 moves the diaphragm 30 into the outer space of the second working chamber 14. Push in direction 14a.

As a result, even if the suction attachment 37 attached to the front surface of the front body 21 is pressed against the face, negative pressure will not be created, and therefore no suction effect on the skin will occur.

Next, when the valve body 27 is pushed in with a fingertip, the spindle-shaped main body portion of the valve body closes the valve port 6.

As a result, the compressed air that has reached the annular passage 10 through the supply cylinder 4 acts on the piston 25, and the piston 25 moves backward in the first working chamber 3 against the elastic force of the compression spring 24. .

At this time, the air in the first working chamber 3 is exhausted to the outside of the housing 20 through the circulation hole 7, the first annular portion 1, and the exhaust hole 19. 30 is the inner chamber 14b due to the action of the piston rod 26.
In contrast, the area inside the outer chamber 14a expands, and the area inside the outer chamber 14a expands through the circulation hole 39, filter 41, and suction port 33
Since the pressure inside the suction chamber 38 communicating with the suction chamber 38 is reduced, the suction attachment 37 adsorbs the face tightly, opens the pores, and sucks out fat, sweat, dirt, etc.

These dirts sucked by the suction attachment 37 do not enter the housing 20 and are absorbed through the circulation hole 3.
9 and the suction port 33.

If the suction attachment 37 is removed from the boss 34,
Since the filter 41 can be removed from inside the boss 34, if the filter 41 becomes dirty, it can be removed in this way and replaced with a new one, or it can be washed with soap.

The embodiments have been described above, and the suction tool of this invention has a first working chamber 3 and a second working chamber 14 in the housing 20, and a feed cylinder 4 is connected to the first working chamber 3. Then, the first
The compression spring 24 is urged into the working chamber to accommodate the piston 25, and a diaphragm 30 is installed in the second working chamber 14 to urge the return compression spring 24 to the rod 26 that is integrated with the piston 25. In addition, a diaphragm 30 is connected to the rod 26 to connect the inside of the second working chamber 14 to the outer chamber 14a.
Further, a suction port 33 is formed in the front part of the housing to communicate between the outer chamber 14a of the second working chamber 14 and the outside of the housing, and a suction attachment 37 is installed in the front part. Further, the first working chamber 3 is provided with a valve port 6, and an exhaust hole 19 that communicates with the second working chamber 14 is provided at a position adjacent to the valve port. The suction tool of this invention is equipped with a finger valve body 27 that manually opens and closes the valve, and a dirt filter is installed near the suction port 33. is used for suction to operate the diaphragm 30 against the elastic force of the compression spring 24 to generate suction force within the suction attachment 37, thereby removing dirt from the skin.

Therefore, according to this invention, the diaphragm can be operated by the pressurizing force itself without using a means to actively generate negative pressure, so there is no need for any suction means, the structure is extremely simple, and the cost is low. This has the advantage that it can be produced in a small amount, and completely eliminates the uneconomical effects of conventional suction tools, which tend to be expensive.
