Description

Air Injection Type Portable Dental Flosses using Double Chamber Air Compressor}

The present invention relates to a portable air jet oral cleaning device that is easy to carry, and introduces a dual-chamber compressed air generator and a rotating nozzle tube to produce a compact product and simultaneously generate and discharge compressed air necessary for oral cleaning. We suggest a new structure of the mouthwash.

1 is a block diagram showing the configuration of a conventional portable mouthwash liquid injection device.

In Fig. 1, reference numeral 1 denotes a body, 2 a lid, 4 a nozzle, 5 a mouthwash liquid, and 6 a nozzle hole. Looking at the operation, when the body (1) is pressed, the oral cavity fluid (5) is sprayed out of the nozzle hole (6) through the nozzle 4 bent in a direction orthogonal to the end portion so that the mouth fluid is easily sprayed between the teeth Have

However, such a portable oral cleaning liquid injector is a device for spraying only the cleaning liquid in a state that does not remove food debris or foreign substances sandwiched between the teeth. Accordingly, there is a problem that does not expect a substantial oral cleansing effect because it does not properly remove the causative agent of the odor or tooth disease inside the oral cavity.

In addition, the use of the interdental toothbrush in order to remove food debris or foreign matter between the teeth is increasing, there is a problem that is difficult to use easily when the user is moving or moving out of the vehicle. In particular, women or users who prefer cleanliness are looking for facilities or tools that can be easily brushed when outdoors or outdoors, but there are no tools that meet the required level.

In addition, there is a problem that it is difficult for the user to cleanly discharge the foreign substances scraped off using the existing interdental toothbrush to the outside of the interdental.

In order to solve the above-mentioned problems, the object of the present invention is as follows.

First, it is an object of the present invention to provide a new concept of oral irrigator capable of discharging interdental foreign substances by discharging powerful compressed air and spraying the cleaning liquid.

Secondly, it is another object of the present invention to provide a new concept of oral irrigator that can reduce the size of the product body and inject powerful compressed air by introducing a double chamber type compressed air generator.

Third, another object of the present invention is to provide a mouthwasher having a new structure that can significantly reduce the length of the entire product when the portable nozzle tube is introduced.

Technical composition of the present invention created to achieve the above object is as follows.

The present invention is the body portion constituting the body of the mouthwash (10); A drive motor 20 installed inside the body portion 10; A cam part 30 connected to the drive motor 20 to convert a rotational motion into a vertical reciprocating motion; A compressed air generating unit 40 connected to the cam unit 30 to generate compressed air according to the reciprocating motion of the cam unit 30; A cleaning liquid storage part 50 installed in the body part 10 and storing the cleaning liquid; A rotatable nozzle pipe (60) rotatably coupled to the upper outer surface of the body portion (10) and used to rotate upward, and serve as a passage through which the compressed air generated by the compressed air generator (40) is discharged; And a nozzle unit 70 rotatably coupled to an end of the rotatable nozzle tube 60 for injecting compressed air supplied through the rotatable nozzle tube 60 to the outside. It is done.

Technical effects of the configuration of the present invention are as follows.

First, the powerful compressed air can be discharged to remove interdental foreign substances and at the same time spray the cleaning liquid.

Second, by introducing a double-chamber compressed air generator can significantly reduce the size of the product body and can also blow powerful compressed air.

Third, the introduction of the rotary nozzle tube can significantly shorten the length of the whole product when carrying.

The cleaning solution storage unit 50 is installed in the body portion 10 and serves as a reservoir for storing the cleaning solution.

Rotating nozzle tube 60 is rotatably coupled to the upper outer surface of the body portion 10 when used to rotate upward, serves as a passage through which the compressed air generated by the compressed air generating unit 40 is discharged.

As shown in FIG. 3, the rotary nozzle tube 60 is installed side by side with the compressed air discharge pipe 61 separately from the compressed air discharge pipe 61 serving as the discharge passage of the compressed air, thereby providing a discharge passage for the cleaning liquid. The cleaning liquid discharge pipe 62 is provided.

The cleaning liquid discharge pipe 62 has a structure in which the compressed air discharge pipe 61 meets the compressed air discharge pipe 61 at the end of the compressed air discharge pipe 61 so that the cleaning liquid is mixed with the compressed air at the end of the compressed air discharge pipe 61 according to the discharge of the compressed air. And then supplied to the nozzle unit 70.

Therefore, the nozzle unit 70 is sprayed through the injection hole 71 in a state in which the cleaning liquid and the compressed air are mixed, and the compressed air discharge pipe 61 is discharged as a structure in which the cross-sectional area is narrowed at the site where the cleaning liquid discharge pipe 42 meets. The speed of the air increases and the pressure decreases to facilitate the discharge of the cleaning liquid.
