Description

Mouthwash

The present invention relates to a device for washing bacteria and foreign matter in the oral cavity.

In order to accurately understand the present invention, knowledge of oral bacteria, that is, knowledge of a field combining medicine, microbiology, and mechanical engineering, is required.

Many kinds of bacteria live in the oral cavity. In the past, many of these bacteria were classified as normal flora, but these bacteria have recently been identified as the cause of various diseases. These bacteria are mainly anaerobic bacteria and do not like air and die when the air touches, so they live in deep air gaps. In the oral cavity, these gaps are large between the teeth and gums and especially the tongue. Tongue has a number of bumps on the upper surface (a taste bud or a papillary bump), and a very small valley is formed between these bumps. Bacteria survive by attaching to the outside of human cells by forming biofilms in these valleys, protecting them from the external environment. The human body mobilizes various immune systems, including white blood cells, to fight bacteria, but since such a biofilm is external to the human body, the human immunity does not reach effectively. Some reports indicate that killing bacteria in these biofilms requires the consumption of approximately 150 times the usual dose of antibiotics, but this is not practical.

Humans have long used toothbrushes and toothpastes to clean their teeth and tongue. However, there is a limit to brushing deep valleys between the teeth and gums and between the protrusions of the tongue with a toothbrush. Recently, water jet cleaners have been developed and used to clean the gaps between the teeth and the teeth or between the teeth and the gums. However, these cleaners are inconvenient because they require a cleaning liquid. At an oblique angle (not a right angle), the fluid sprayed from these nozzles did not reach the depths of the valley and was not effective in killing or wiping out the bacteria living in the depths of the valley.

The present invention compresses air with a scrubber to remove bacteria present in the oral cavity, and ejects compressed air to one or several jet openings opened at right angles to the longitudinal direction of the nozzle to between teeth and gums or between protrusions of the tongue. It is a device that shoots air deep into the gap. In addition, the nozzle is installed by separating the nozzle from the pump of the oral irrigator and inserted into the nozzle mounting groove provided on the side of the pump housing for convenient portability. In addition, the power source of the pump uses a rechargeable battery to increase convenience. In some cases, such a mouthwashing device may be installed to be detachably attached to the cleaning solution container containing the cleaning solution, thereby enabling cleaning using the cleaning solution.

Since the present invention does not require a cleaning solution, it can clean the oral cavity anytime and anywhere, and effectively removes bacteria present in the valleys between the teeth and the protrusions of the tongue and can easily replace all the toothpaste and toothbrush in the future. There will be.

A narrow, deep valley is formed between the teeth and the gums. The tongue has numerous bumps, such as tiny taste buds, that form a narrow and deep valley between them. Deep in these valleys, anaerobic bacteria that hate air form biofilms to protect themselves from the outside and nourish human food intake. There is a huge number of bacteria in the gaps as small as 1 micron. Some of these bacteria enter the blood vessels through the intercellular gaps of the human body, causing various diseases. There are many new papers on the harmfulness of these bacteria recently, and I believe that many unknown diseases are directly related to these oral bacteria.

Hereinafter, with reference to the drawings will be described in detail the present invention. The present invention consists of a nozzle, a pump, a rechargeable battery and a housing.

The nozzle is a hollow, long pipe. One end of the nozzle has a nozzle tip 12 with a nozzle 11 for injecting air and the other end has a nozzle connection 14 which is connected to the outlet 211 of the pump and connects the nozzle tip and the nozzle connection. There is a nozzle body 13. There are two types of nozzles. One is a nozzle with a single nozzle 11 and the other is a nozzle with several nozzles 15.

First, a nozzle having a single injection port 11 will be described. The nozzle tip 12 is bent at one end of the nozzle body 13 in a direction perpendicular to the longitudinal direction of the nozzle body so that the inner and outer diameters become narrower, and at one end thereof, one injection hole 11 in the direction perpendicular to the longitudinal direction of the nozzle body 11. ) Is open. The other end of the nozzle body 13 has a connection portion 14 which is detachably connected to the discharge port 211 of the pump receives compressed air from the pump. In such a nozzle having a single nozzle, the air from the nozzle opening is ejected at right angles to the longitudinal direction of the nozzle body so that the nozzle can be easily rubbed into and between the teeth and the gums to effectively clean the gap deeply.

Next, a nozzle having a plurality of injection holes 15 will be described. A nozzle with multiple nozzles is the same as a nozzle with a single nozzle except for the nozzle tip. The nozzle tip of the nozzle having several nozzles is bent at one end of the nozzle body in a direction perpendicular to the longitudinal direction of the nozzle body, and the cross section is changed into an elliptical shape. At the end of this nozzle tip, several jets are opened at right angles to the length of the nozzle body. Such a nozzle having several nozzles is effective for cleaning a relatively large area such as a tongue.

The pump 20 includes a cylinder cover 21, an exhaust valve 27, a cylinder 22, a piston 28, an intake valve 29, a crank 25, and a motor 26.

The cylinder cover 21 is a funnel shape as a whole, the discharge port 211 is open on one side and the cylinder 22 is in contact with the other. The discharge port 211 is coupled to the nozzle connecting portion 14 to be detachable. The inner side of the cylinder cover includes a guide jaw 213 for guiding the four-way protrusion 271 of the exhaust valve 27 and a projection jaw 214 for restricting movement of the exhaust valve in the discharge port direction. The diameter of the inlet 212 is larger than the diameter of the disk of the exhaust valve 27.

4 shows an exhaust valve 27. 7 is a view showing a state in which the pump sucks air. The exhaust valve 27 has a disk shape as a whole, and four four-way protrusions 271 protrude. The diameter of the disk-shaped circumference is smaller than the inlet inner diameter 212 of the cylinder cover 21 and larger than the diameter of the outlet 221 of the cylinder 22. Meanwhile, four four-sided protrusions protruding from the disk shape are larger than the inner diameter of the cylinder cover inlet 212. The exhaust valve moves up and down (nozzle side) according to the air pressure between the cylinder outlet 221 and the protruding jaw 214 of the cylinder cover 21. At this time, the exhaust valve is guided by the guide protrusion (213). In this embodiment, the four projections, but the four examples are not necessarily four. That is, there may be two or three protrusions.

The cylinder 22 refers mainly to a structure that allows the reciprocating movement of the piston 28 therein mainly in a cylindrical shape or in this embodiment includes all of the various structures extending and attached to the cylindrical shape. The cylinder is closed in contact with the cylinder cover 21 outside the outlet 221 of the cylinder cylinder, and the other side is opened in the air through the inlet 222. A structure extending from the cylinder of the cylinder is provided with a charging terminal 23 for supplying electricity to the rechargeable battery 30 and a switch 24 for connecting or disconnecting the electricity supply to the rechargeable battery.

The piston 28 is a structure in which the cylindrical outer circumferential surface 284 is in a cylindrical shape and reciprocates linearly in contact with the inside of the cylinder. The piston has a connecting projection 282 for connecting with the crank from the cylindrical shape and is axially coupled 283 with the crank. A hole 285 through which air enters and exits is formed in the cylindrical shape of the piston, and an intake valve 29 is fitted in the hole.

The intake valve 29 is inserted into the piston cylindrical inner hole 285, and the two legs 293 protrude in the shape of two discs overlapping the small disc 292 and the large disc 291. There is a locking jaw 294 extending outwardly on both sides. The two legs are smaller than the piston inner hole 285, the discs are larger than the piston inner hole 285, and the locking jaw 294 is also larger than the piston inner hole. The intake valve moves up and down in the piston 28 according to the air pressure to close and open the hole between the intake valve and the piston, thereby opening or closing the flow of air. At this time, since the moving distance of the intake valve with respect to the piston is limited by the

discs

291 and 292 and the locking jaw 294, the intake valve is not completely separated from the piston.

The crank 25 is axially coupled to the connecting projection 282 of the piston 28 at one end and axially coupled to the crankshaft of the motor 26 at the opposite end to convert the rotational force of the motor into a linear movement of the piston 28. .

The motor 26 receives electric power from the rechargeable battery 30 to generate rotational force. The motor has a crank shaft provided eccentrically with the rotation shaft of the motor, and the crank shaft is axially coupled with the crank 25. Since the crank shaft is eccentric with respect to the rotation axis of the motor, the rotational force of the motor changes through linear movement of the piston while passing through the crank. There are many examples of such mechanisms, such as car engines, and are not described here any further.

The rechargeable battery 30 receives electricity from the outside to store electricity and supplies electricity to the motor.

In this embodiment, a system using a piston cylinder as an example of a pump mechanism for air compression is exemplified, but it is not necessary to use only such a pump. Any type of pump on the market can be applied.

The housing 40 is a case surrounding the pump 20 and the rechargeable battery 30. On one side of the housing there is a space 41 which is bent so that the connection portion 14 of the nozzle can be coupled to the outlet 211 of the pump. The other side of the housing is formed with an open window 42 so that air can be supplied to the inlet 221 of the pump. Another side of the housing is provided with at least one nozzle mounting groove 43 for mounting the nozzle. 9 is a perspective view showing a state in which a nozzle having a single injection hole is coupled to the pump discharge port 211 and a nozzle having a plurality of injection holes is mounted in the nozzle mounting groove.

Hereinafter will be described the operation of such a mouthwash. First, referring to FIG. 8, an exhaust process for discharging air inside a cylinder to a discharge port will be described. When electricity is supplied from the rechargeable battery 30 to the motor 26 by turning on the switch 24, the piston 28 connected to the crank 25 goes up in the discharge port 211 direction. At this time, the intake valve 29 moves in a direction relatively opposite to the piston movement direction due to the pressure difference and inertia to block the hole 285 in the piston to prevent the air inside the cylinder from flowing back to the inlet 221. At this time, the air in front of the piston travels toward the discharge port through the space between the exhaust valve 27 and the cylinder cover inlet 212. Arrows shown in FIG. 8 indicate the movement direction of air during exhaust.

Next, the suction process will be described with reference to FIG. 7. When the piston 25 moves in a direction opposite to the discharge port, the intake valve 29 moves in a direction opposite to the direction of movement of the piston to open a hole in the piston. At this time, the inside of the cylinder is negative pressure. Air enters inside. At this time, the exhaust valve 27 is in contact with the cylinder outlet 221, the air inside the cylinder cover 21 does not flow back toward the cylinder. Arrows in FIG. 7 indicate the direction of movement of air at intake.

Next, the use of such a mouthwash will be described. When the nozzle is connected to the discharge port of the pump and the switch is turned on and the motor is turned on to operate the pump, air is introduced into the pump inlet, the air is compressed and sent to the nozzle, and compressed air comes out through the nozzle at the nozzle tip. . At this time, when the nozzle tip approaches the valley between the teeth and the gum, the valley opens and compressed air is injected into the valley to remove and kill the bacteria living therein. When cleaning the tongue, it is more convenient to use nozzles with multiple nozzles than nozzles with a single nozzle. After use, these nozzles are separated from the pump discharge port and mounted in the nozzle mounting groove installed on the side of the housing.
