Description

[0001] Non power portable water toothpick [0002]

The present invention relates to an oral cleanser used for cleansing oral cavity and interdental space, and more particularly, to an oral cleanser which can be cleaned by a non-power source and is easy to adjust spray pressure of cleansing water and safe and easy to use without risk of pressure explosion. The present invention relates to an oral cleanser.

Generally, mouthwashers used to clean the oral cavity can be divided into electric mouthwashers and hydraulic mouthwashers according to the method of extruding water. The electric mouthwasher requires a power source for driving the electric motor, which is bulky and expensive, which is inconvenient to carry and burdens the purchase cost. Although the water pressure type oral cleanser is miniaturized due to its small volume, it still requires a large number of batteries for power supply, and it is inconvenient to carry by the weight of the battery, and in case of discharging, replacement or charging time is required.

Japanese Patent Application Laid-Open No. 2004-73558 (oral cleaning mouth) has been proposed as a background of the present invention. This is because the reciprocating pistons are manually reciprocated in the cylinder and the compressed air is stored in the air cylinder to discharge the compressed air (or compressed liquid) from the nozzle as a jet stream to remove foreign matter stuck between the teeth and the teeth, . However, the background art requires a cumbersome manual operation to fill the air bubbles with compressed air, and there is a limit in raising the pressure of the compressed air by hand, which limits the spraying ability, that is, the cleaning power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

1 to 3, the non-powered portable oral cleaner 10 according to the present invention presses the spray button 22 on the functional gas (or liquefied gas) compressed in the gas pressure cylinder 14, So that the pressure inside the water feed cylinder 16 is increased so that the washing water in the water feed cylinder 16 is injected through the injection nozzle 18 to perform oral and interdental washing. In this case, cleansing water is an example of a functional gas, and oxygen is dissolved in oxygen, which is injected into the oral cavity, thereby enabling the removal of odors by bacteria decomposition and cleaning of the foreign substances adhered to the teeth. As another example, when carbon dioxide gas is used, it is possible to have a fresh and tangy washing taste.

The non-powered portable mouth washer 10 has a scrubber body 12.

As shown in Figs. 2 and 4, the scrubber body 12 has a pressure discharge passage 121a and a pressure discharge hole 121b, which are in communication with each other at one end in a cylindrical shape, ). The pressure discharge passage 121a is disposed on the central axis of the scrubber body 12 and the pressure discharge hole 121b is formed in a direction perpendicular to the pressure discharge passage 121a in this embodiment, .

The scrubber body 12 is provided with a tubular connection sleeve 121 having one end communicated with the pressure discharge passage 121a and the other end closed to form the pressure exhaust hole 121b, Type elastic valve 13 which is opened by the gas pressure discharged from the gas pressure cylinder 14 by closing the pressure exhaust hole 121b with elasticity. The tubular resilient valve 13 may be made of rubber or silicone.

The sprayer body 12 is provided with a spray button 22 which is inserted into the button assembly 12a and protrudes by a predetermined amount to operate a gas control valve unit 20 to be described later.

The gas pressure cylinder 14 is assembled to the scrubber body 12 via the gas regulating valve unit 20. The gas pressure cylinder 14 is filled with compressed gas at a high pressure in a liquefied state. In the present invention, the term 'compressed gas' is defined as a term collectively referred to as compressible gas which does not cause damage to the oral cavity and teeth. For example, the compressed gas may be oxygen, carbon dioxide, chlorine, or the like. The gas pressure cylinder 14 is assembled by screwing the screw portion 141 so as to be detachable from the gas control valve unit 20 and the outlet is opened and closed by the valve pin 142. Since the operation structure of the valve pin 142 in the gas pressure cylinder 14 is well known in the art, a detailed description thereof will be omitted.

The gas control valve unit 20 regulates the discharge amount of the compressed gas in the gas pressure cylinder 14 to be ejected to the pressure exhaust hole 121b. The gas control valve unit 20 includes a bypass passage 201a communicated with the pressure discharge passage 121a, a plunger operation chamber 201b positioned in a direction perpendicular to the bypass passage 201a, And a valve body 201 having a pressure cylinder connection port 201c to which the cylinder 14 is screwed. The valve unit 20 for gas control is composed of a ball plunger 202 slidably inserted in the plunger operating chamber 201b and a bypass valve 201a located in the bypass passage 201a, A spring ball 204 inserted into the upper portion of the plunger operating chamber 201b and assembled to the spray button 22, And a pressure regulating spring 205 provided between the ball plunger 204 and the ball plunger 202.

Here, the diameter of the valve ball 203 is configured to be smaller than the diameter of the bypass passage 201a so that the compressed gas can sufficiently leak out. The ball plunger 202 has a conical tapered portion 202a for increasing the amount of movement of the valve ball 203 according to the amount of descent in the lower portion. In addition, it is preferable that a circumferential surface of the ball plunger 202 is further provided with a car-accommodating chamber 206 which is in circular contact with the plunger operating chamber 201b and has an inverted V-shaped cross section. The car accommodation room 206 may be made of, for example, rubber, silicone, or a soft resin.

The water supply tube 16 is detachably coupled to the tip of the scrubber body 12 through a screw connection. The water supply cylinder 16 has a cylindrical structure, and its distal end portion has a conical structure whose cross section gradually decreases, and a female thread is formed at the rear end thereof to be screwed to the cleaner body 12. At this time, a sealing member 61 (for example, an O-ring) is provided between the junction of the water supply cylinder 16 and the cleaner body 12 in order to block watertightness. The water supply cylinder 16 is filled with a rinse water through a water supply port 161 and a compressed gas in the gas pressure cylinder 14 is introduced into the water supply cylinder 16 through the gas control valve unit 20.

2 and 5, the injection nozzle 18 is coupled to the nozzle-side nozzle assembly 165 of the water supply cylinder 16 and is exposed to the outside. The spray nozzle 18 has a shape of a long tube with an outer diameter narrowed toward the tip and a certain section of the tip is inclined toward the spray button 22. The injection nozzle 18 is fitted in a rear end to the nozzle coupling 51 coupled to the water supply cylinder 16. [ At this time, the jetting nozzle 18 has a length sufficient to allow the jetting port 18a to be positioned to the inside of the mouth. The spray nozzle 18 is provided at the rear end side with a catching step 18b which is rotatably coupled to the inner surface of the nozzle coupling 51. The nozzle coupling 51 is engaged with the hook coupling 52, 16).

7, after the washing water is exhausted, the spray nozzle 18 is separated from the water supply tube 16 and then inserted into the nozzle connection port 321 on the side of the safety valve unit 30 to be described later, (16). Therefore, the volume of the non-powered portable oral care device 10 is reduced, which makes it convenient to carry.

Preferably, a wash water discharge hose 19 connected to the spray nozzle 18 is installed in the water supply tube 16 so as to maximize the use of the wash water. The cleaning water discharge guiding hose 19 has one end connected to the injection nozzle 18 side and the other end disposed close to the bottom side of the water supply tube 16.

On the other hand, the water supply port 161 of the water supply cylinder 16 may be further provided with a safety valve unit 30 capable of removing a pressure higher than the set pressure raised by the gas pressure and capable of opening and closing by water supply and reception.

2 and 6, the safety valve unit 30 includes a safety cover 31 having an exhaust hole 31a and being screwed to the water supply port 161 side to open and close the water supply port 161, an inlet port 321a, And a relief spring 34 for pushing the valve poppet 33 to the inflow and outflow port 321a. The valve housing 32 includes a valve housing 32, a valve housing 33 and a relief spring 34.

The valve housing (32) is screwed into the safety cover (31) and positioned in the water supply port (161). The valve housing 32 includes a nozzle connection port 321 capable of receiving and connecting the injection nozzle 18 separated from the scrubber body 12 within the scrubber body 12 and a nozzle connection port 321 communicating with the nozzle connection port 321 And a valve operating chamber 322. The valve poppet 33 is inserted into the valve operation chamber 322 to open and close the inflow / outflow port 321a. The relief spring 34 has one end supported by the valve poppet 33 and the other end supported by the safety lid 31 and assembled in a compressed state. The safety cover (31) is assembled with a leak-barrier packing (35) to seal the water supply port (161).

Accordingly, when the pressure in the water supply cylinder 16 is excessively increased, the relief spring 34 is compressed to open the valve port 331 to the inlet port 321a, and the pressure in the exhaust hole 31a is removed.

The reference numeral '207' is 'O-ring for confidential maintenance'.

The operation and use of the non-powered portable oral cleaner 10 thus constructed will be described.

The spray button 22 is partially protruded from the outside of the scrubber body 12 by the initial compressive force of the pressure regulating spring 205 before the spray button 22 is pressed as shown in FIG. And the gas pressure cylinder 14 is closed in a state in which the valve body 202a is in contact with the valve ball 203. [ That is, the state before the pressing force is applied to the valve pin 142 for opening and closing the gas pressure cylinder 14 is obtained.

First, the injection nozzle 18 is exposed to the front of the water supply cylinder 16, and the safety valve unit 30 is separated from the water supply cylinder 16 using the safety lid 31, And is filled into the water supply tube 16 through the opening 161. Thereafter, the safety cover 31 is fastened to the water supply port 161 and closed.

4B, the pressure regulating spring 205 is compressed and the ball plunger 202 moves downward to move the valve ball 203 to the gas The valve pin 142 is retracted and the outlet of the gas pressure cylinder 14 is opened. At this time, the outlet of the gas pressure cylinder 14 increases in accordance with the operation amount of the spray button 22.

When the outlet of the gas pressure cylinder 14 is opened, the compressed gas is introduced into the water supply cylinder 16 through the bypass passage 201a, the pressure discharge passage 121a, and the pressure discharge hole 121b of the valve body 210. At this time, the pressure relief hole 121b is opened while the tubular elastic valve 13 is expanded by the discharge pressure of the compressed gas.

Therefore, the compressed gas is introduced into the water supply tube 16 to increase the internal pressure, so that the washing water is rapidly injected through the injection nozzle 18 via the discharge inducing hose 19. At this time, the spray amount of the washing water is proportional to the spray button 22 being pressed. Therefore, the oral teeth and teeth can be easily cleaned. In addition, when the introduced compressed gas is oxygen, the dissolved oxygen is hydrated in the sprayed washing water so that the anaerobic bacteria in the oral cavity can be decomposed and the odor can be removed.

On the other hand, when the pressure in the water supply cylinder 16 is excessively increased, the valve poppet 33 at the side of the safety valve unit 30 overcomes the force of the relief spring 34 and can be safely used by removing the open pressure to the atmosphere.

Thereafter, when the pressing force of the spray butt 22 is removed, the ball plunger 202 rises to the original position and the outlet of the gas pressure cylinder 14 is closed. At the same time, the tubular resilient valve (13) being opened is also closed and the injection is stopped.

As described above, the oral cleaner 10 of the present invention has a spray button 22 to easily control the use pressure and the cleaning amount. In particular, since it is a non-power-source driving system that injects washing water with a compression pressure in the gas pressure cylinder 14, it has an advantage that a battery, a driving circuit, and an actuator are not required. Also, it is convenient to carry and use so that it can be used regardless of time and place, and can be conveniently used when toothbrushing is difficult during tooth treatment. In addition, use of oxygen filled in the gas pressure cylinder 14 can be usefully used for prevention and inhibition of oral diseases. And can be cleaned several tens of times without replacement of the gas pressure cylinder 14 due to its excellent spraying power. Further, once the oxygen filled in the gas pressure cylinder 14 is exhausted, the gas pressure cylinder filled with new oxygen can be replaced and reused.

In the meantime, in the present invention, a water ball 3 made of activated carbon may be charged into the water supply tube 16 as shown in FIG. Therefore, the foreign substances contained in the washing water filled in the water supply tube 16 can be adsorbed and have the effect of purification.

On the other hand, the present invention can also be used by optionally disconnecting the injection nozzle 18 from the water supply bottle 16 and connecting the handy nozzle 70 to the nozzle assembly 165 as shown in FIG.

The handy nozzle 70 includes a nozzle connection port 71 fitted to the nozzle assembly 165 of the water supply bottle 16, a connection tube 72 having one end connected to the nozzle connection port 71, A handy cover 74 assembled with the nozzle holder 73, a nozzle chamber 75 coupled to the nozzle holder 73, and a nozzle holder 73 which are screwed to the nozzle holder 73, A connection socket 76 for fitting the nozzle 75 to the nozzle holder 73 and a spray nozzle 77 fitted to the nozzle chamber 75 and fitted to the connection socket 76, A handy cover cap 78 that is coupled to the nozzle holder 73, and a magnet 79 mounted on the nozzle holder 73 side.

Accordingly, the handy nozzle 70 has an advantage that the injection nozzle 77 is connected through the flexible and long connection tube 72, so that the handy nozzle 70 can be used lightly and freely. In addition, the handy nozzle 70 is provided with a magnet 79 therein to be magnetically attached to the cleaner body 12, thereby facilitating management during use. At this time, the scrubber body 12 may be made of iron metal capable of adsorbing the magnet 79, or may be made of iron metal.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
