[0002] Oral care can improve the oral environment and prevent diseases. To improve the oral environment: Take good oral care measures on a regular basis, keep the mouth clean and moist, remove tooth stains and food debris, which can improve oral odor, increase oral comfort, and reduce adverse reactions. To prevent diseases: Take good oral care measures on a regular basis, which can effectively prevent oral diseases such as caries, apical periodontitis, periodontitis, etc.

[0003] In the process of oral care, in addition to cleaning the teeth and tongue coating, it is also necessary to assist in disinfecting the inner wall mucosa of the oral cavity, control harmful bacteria in the oral cavity, and reduce the risk of inflammation and other oral diseases. The existing oral disinfection sprayer adopts a single-press press-type sprayer that sprays once. When in use, it is necessary to press multiple times and spray multiple times to disinfect the inner wall of the oral cavity. When pressing multiple times, the thumb and other fingers need to cooperate. Each press will cause the position of the nozzle to change, the spray action position is unstable, and the spray effect is discontinuous, and the amount of disinfection spray each time cannot be stably determined. In view of the above problems, a sprayer for oral disinfection is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a sprayer for oral disinfection, comprising a shell 1, a liquid storage capsule 12 is mounted on the outer side of the shell 1, a drainer 2 is mounted on the right side of the shell 1, a nozzle 3 is mounted on the top of the drainer 2, and the liquid storage capsule 12 is connected to the top of the drainer 2 through a connecting pipe 27;

[0026] A one-way valve is installed at the position where the liquid storage bag 12 and the drainer 2 are connected, and the flow direction of the liquid is from the liquid storage bag 12 to the drainer 2;

[0027] The bottom end of the drainer 2 is equipped with a rubber plug 22, and the right side of the shell 1 is slidably equipped with a button 15, which can drive the rubber plug 22 to rise and fall. The bottom end of the rubber plug 22 is equipped with a spring 17, and the maximum release position of the spring 17 drives the rubber plug 22 to be located at the top of the shell 21.

[0028] The utility model is provided with a liquid storage bag 12 and a liquid discharger 2 with separate storage of liquid. When in use, the button 15 is pressed to drive the sliding frame 14 to drive the bracket 26 and the second rubber plug 22 to move downward and compress the second spring 17, so that negative pressure is formed inside the shell 21, and the first rubber plug 18 inside the liquid storage bag 12 is driven to rise upward, and then the liquid is transmitted to the inside of the shell 21 through the one-way movable valve 25. When the button 15 is released, the second spring 17 releases the stress to squeeze the bracket 26 upward, drives the second rubber plug 22 to move upward, squeezes the liquid out of the inside of the nozzle 3, and uses the atomization effect of the nozzle 33 to provide a quantitative spraying effect, which effectively solves the problems of the existing oral disinfection sprayer using a single-press press-type sprayer with a small spray volume and discontinuity, and the nozzle position is unstable during the pressing process, and is not stable enough during single-point spraying.

[0029] Specifically, the housing 1 includes a handle tube 11, a slide groove is opened on the right side of the handle tube 11, a sliding frame 14 is fixedly installed on the inner side of the button 15, a spring 16 is installed inside the slide groove, and the spring 16 is installed between the slide groove and the button 15. When pressed, the spring 16 is stretched by the button 15. After the button 15 is released, the spring 16 retracts and drives the button 15 to return to its position upward, releasing the bracket 26 and the spring 2 17.

[0030] Specifically, a baffle 19 is welded to the inner side of the bottom end of the liquid storage capsule 12, and the rubber plug 18 is slidably sealed to the inner wall of the liquid storage capsule 12. When a one-way negative pressure is formed inside the shell 21, the external air pressure will push the rubber plug 18 upward through the center of the baffle 19, driving the internal liquid to enter the inside of the shell 21 through the movable valve 25;

[0031] The friction between the first rubber plug 18 and the inner wall of the contact position is smaller than the friction between the second rubber plug 22 and the housing 21. When the second rubber plug 22 moves, the suction force of the sealed air extraction is larger than the sum of the friction of the first rubber plug and the gravity of the liquid.

[0032] Specifically, the drainer 2 includes a shell 21, a discharge pipe 23 is integrally formed in the middle of the top of the shell 21, a connecting head 24 is integrally formed at the edge of the shell 21, a movable valve 25 is assembled inside the connecting head 24, the top of the connecting head 24 is fixedly connected to the connecting pipe 27, and the movable valve 25 assembly has elastic force. In the absence of external force, the movable valve 25 is pressed upward on the inner wall of the connecting head 24. When the rubber plug 22 moves downward, the liquid pushes open the rubber sheet and the sealing ball, and the liquid enters the interior of the shell 21 from the top opening. When the rubber plug 22 works upward, the spring stress is converted into a stable hydraulic pressure, and the liquid pressure holds the rubber sheet. Therefore, the liquid can only enter the interior of the shell 21 in one direction, and will not flow back to the interior of the liquid storage bag 12 through the connecting pipe 27, thereby achieving the effect of single quantitative liquid extraction.

[0033] Specifically, a sliding round rod is welded to the bottom end of the rubber plug 22, a bracket 26 is welded to the bottom end of the round rod, the sliding frame 14 is sleeved on the outer wall of the round rod, between the top end of the bracket 26 and the rubber plug 22, the sliding frame 14 is slidably assembled between the bracket 26 and the rubber plug 22, and the position of the sliding frame 14 is restricted without affecting the displacement position of the rubber plug 22.

[0034] Specifically, the top end of the grip tube 11 is sleeved with an outer cover 13 , which can be buckled with the grip tube 11 and can fold and accommodate the nozzle 3 .

[0035] Specifically, the nozzle 3 includes a fixed tube 31 , a bellows 32 is fixed to the top end of the fixed tube 31 , and a nozzle 33 is provided outside the bellows 32 .

[0036] Specifically, the bellows 32 is a folded bellows structure, which can form a displaceable, flippable and shaped bellows structure between the fixed tube 31 and the nozzle 33, and can be shaped or folded and stored at a suitable angle when in use.

[0037] Specifically, the middle part of the movable valve 25 is a sliding rod structure with a spring, a sealing ball is integrally formed on the top of the sliding rod, a rubber sheet is integrally formed on the outside of the sealing ball, the bottom end of the spring is fixedly arranged on the inner wall of the connecting head 24, the sliding rod and the connecting head 24 are coaxially slidably arranged, a round cover is fixed on the top of the connecting head 24, a ball opening is opened in the center of the round cover, and the sealing ball is in close contact with the ball opening.

[0038] Specifically, a groove is provided in the middle of the side wall of the rubber plug 22. When in use, the groove structure of the side wall of the rubber plug 22 forms an annular rubber ring structure at the top and bottom ends of the rubber plug 22, thereby improving the softness, thereby improving the tightness of the contact, and improving the sealing performance.
