Next, the operation of the portable air pick configured as described above will be described.

3 is a view showing a state in which the rod part is moved forward in the second embodiment of the present invention.

In order to use the portable air pick of the present invention, the user holds the housing unit 100 in his hand and presses the push unit 250 using his or her thumb.

When the push part 250 is pressed, the piston 211 of the pressing part 210 moves forward while the seal 212 moves relatively rearward in the sealing accommodation groove 211b, and the transverse through groove 211c) will close

Accordingly, the air between the piston 211 and the shield 110 is pressurized and becomes high pressure, and when the pressure increases above a certain pressure, the one-way valve 310 is opened.

Due to this, the air in the pressure chamber (c) acts to be introduced into the pressure tank unit 300 through the air inlet port (i).

4 is a view showing a state in which the rod part is moved rearward in the second embodiment of the present invention.

On the other hand, when the force applied to the push unit 250 is released, the rod unit 200 is moved backward again by the spring 130 .

At this time, due to the rearward movement of the piston 211, the seal 212 moves relatively forward in the seal accommodating groove 211b to open the transverse through-groove 211c.

The air introduced through the air inlet groove (a) formed on the side of the pressurization chamber (c) flows into the transverse through-groove 211c and flows into the front end of the piston 211 through the axial through-groove 211a. It serves to supply the necessary air during compression.

On the other hand, while the pressure of the push part 250 and the linear reciprocating motion of the piston 211 by the spring 130 are repeated, the magnet part 240 of the rod part 200 also linearly moves the inside of the coil part 140 . As a result, the reciprocating motion is naturally repeated.

As a result, an electromagnetic induction phenomenon occurs between the magnet unit 240 and the coil unit 140 to generate a current, and the generated current is converted by the power control unit 150 and serves to store electricity.

Accordingly, in the present invention, when the linear sliding reciprocating motion of the rod part 200 for air compression is performed, the power generation action is simultaneously accompanied without a separate power generation action.

In the present invention, electricity, which requires a large amount of energy to operate a pump for air compression, is not required.

Only a small amount of electricity is required for the operation of the simple electronic circuit inside the product. For example, only electricity required for operation of the solenoid at the valve v, the operation of the pointer 410, the pressure sensor 322, the pressure indicator light 323, and the like is required.

Accordingly, it is possible to secure sufficient electric power required for the product only by the power generation action only by the linear reciprocating motion as in the present invention.

In addition, since a small amount of electricity is consumed, it is not necessary to install a heavy battery for power storage, so that the product can be made light and lightweight.

On the other hand, since the linear sliding reciprocating motion is made by the repetitive pressing motion of the push unit 250 by the thumb or the like, it can be performed in a fun way as if playing with the rear end of a ballpoint pen, so that the repetitive motion can be performed without difficulty.

When the pressing motion of the push part 250 by the thumb or the like is difficult or cumbersome, the extended grip part 270 having the hook part 271 is mounted on the rear end of the push part 250 to pull the push part 271 by the loop part 271 . In the case of performing the operation, it is possible to more easily pull the rod part.

When it is confirmed by the indicator light 323 that the pressure tank unit 320 is sufficiently filled with air by the above-described action, the air pick is operated.

When the user operates the switch (s) to use the air pick, the valve (v) is opened and the air of the pressure tank unit 320 passes through the flow path (f) and is injected from the end of the injection unit 400 . will do

Therefore, in the present invention, it is possible to clean the oral cavity using air without using water.

For this reason, it has the effect of being able to perform dental treatment even in daycare facilities for the disabled who do not professionally provide cleaning water or outdoors where it is difficult to secure water.

In addition, since water is not used, corrosion of electronic components of the oral irrigator caused by water or occurrence of malfunction due to electric leakage is prevented, thereby improving durability and reliability of the product.

Meanwhile, in the present invention, when the pressure tank unit 320 is formed of a material that does not undergo volume deformation, the volume of the pressure tank unit 320 continues to maintain a constant state.

Accordingly, in this case, the air injected through the injection valve is initially injected at a high pressure, but the pressure and flow rate decrease as time passes.

When the pressure tank part 320 is formed of the elastic pressure tank part 321 in which the material is elastically deformable, the volume of the pressure tank part 320 is reduced while air is sprayed, and the internal pressure of the pressure tank part 320 is constant. Therefore, the pressure and flow rate of the injected air are also kept constant, thereby having an advantageous effect for the user's use.

In the present invention, when the pointer 410 is installed at the end of the spray nozzle of the air pick, it is possible to precisely aim and clean the part to be cleaned in the oral cavity.

For example, in the case of removing foreign substances such as food between teeth, the pointer 410 is operated by the primary operation of the switch s to aim the correct cleaning point, and then, by the secondary operation of the switch s It can be operated to blow air.
