Description

Technical Field

[0001] The present invention relates to the technical field of water flossers, and in particular to a water flosser capable of controlling water pressure through pressure sensing. Background Art

[0002] The water flosser is an auxiliary tool for cleaning the oral cavity. It uses pulsed water flow to clean teeth and the gaps between teeth. When people eat various foods in their daily lives, residues will be left in the gaps between teeth, which is sometimes difficult to clean with a toothbrush alone. The water flosser can spray high-pressure liquid into the oral cavity. The high-pressure liquid can effectively remove the residues in the gaps between teeth and ensure that the teeth are clean.

[0003] Because different areas of the mouth have different sensitivities and contamination levels, many consumers may need to switch to different water pressures to clean different areas to avoid damage to the mouth. Current water flossers are usually equipped with mechanical buttons, which are used to set different modes to control the water pressure. However, when switching the water pressure, the water flosser needs to be turned off and then switched, and then placed in the mouth for cleaning. The operation is cumbersome and cannot meet the needs of users.

[0004] At the same time, most of the water pumps used in oral irrigators currently on the market are piston water pumps, which achieve the purpose of sucking in and discharging liquid through the reciprocating motion of the piston, thereby generating a high-pressure water flow for flushing teeth. When working, the piston will be in close contact with the inner wall of the pump body and produce friction, which is prone to wear after long-term use, and then cause liquid leakage, affecting the service life of the oral irrigator. Summary of the invention

[0005] In view of the defects of the above-mentioned prior art, the present invention provides a water flosser that controls water pressure through pressure sensing. The force applied at the thin-wall touch position is transmitted to the pressure switch through the elastomer to achieve control of the water flow force of the water flosser. The operation is simple and convenient, and meets the user's usage needs.

DETAILED DESCRIPTION

[0022] In order to more clearly explain the structural features, technical means and specific purposes and functions achieved by the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0023] This embodiment: Figure 1-3As shown, a water flosser that controls water pressure by pressure sensing includes a water flosser body, the water flosser body includes a housing 10, a control mechanism and a water flossing mechanism, and the control mechanism and the water flossing mechanism are both disposed in the housing 10;

[0024] The control mechanism includes a main control circuit board 20 and a pressure switch 21. The pressure switch 21 is arranged on the main control circuit board 20. A thin-wall touch position 11 is arranged on one side wall of the housing. The thin-wall touch position 11 is attached to the pressure switch 21 through an elastic body 12. The elastic body 12 is silicone.

[0025] The tooth flushing mechanism includes a water tank 30, a water outlet 31 and a water pump 32. The water pump 32 is connected to the main control circuit board 20. The water pump 32 includes a water flow component and a transmission component. An elastic sealing body 33 is provided between the water flow component and the transmission component. The water flow component includes a water storage pipe 40, a one-way water outlet valve 41 and a one-way water inlet valve 42. The elastic sealing body 33 is arranged at the bottom of the water storage pipe 40 to form a water storage cavity 43 in the water storage pipe 40. The elastic sealing member is bowl-shaped, and the edge of its opening is provided with an outward-turned connecting ring 331. The inner wall of the bottom of the water storage pipe 40 is provided with an annular groove 401 adapted thereto. The connecting ring 331 is installed in the annular groove 401, so that the elastic sealing member is installed at the bottom of the water storage pipe 40. The water tank 30 is connected to the water storage cavity 43 through a water inlet pipe 44. The water nozzle 31 is connected to the water storage chamber 43 through the water outlet pipe 45, the one-way water inlet valve 42 is umbrella-shaped, and the one-way water inlet valve 42 is arranged at the connection between the water inlet pipe 44 and the water storage chamber 43, the one-way water outlet valve 41 is duckbill-shaped, and the one-way water outlet valve 41 is arranged at the connection between the water outlet pipe 45 and the water storage chamber 43, the transmission assembly includes a motor 50, an eccentric face gear 51 and a connecting rod 52, the motor 50 is connected to the eccentric face gear 51, and the eccentric face gear 51 is connected to the elastic seal through the connecting rod 52, the bottom of the elastic seal is provided with an undercut hole 332, the upper end of the connecting rod 52 is provided with an undercut boss 53, the undercut boss 53 is inserted into the undercut hole 332, so that the connecting rod 52 is connected to the elastic seal, and the elastic seal is driven to stretch downward by the connecting rod 52;

[0026] A UV sterilizer lamp 60 is provided on the top of the water tank 30. A light-transmitting hole 61 is provided on the top of the water tank 30. A quartz glass 62 is installed in the light-transmitting hole 61. The UV sterilizer lamp 60 is installed on the quartz glass 62 with the light facing downward. The quartz glass 62 is installed on the light-transmitting hole 61 through a sealing waterproof glue. The UV sterilizer lamp 60 is connected to a control light board 63. When the UV sterilizer lamp 60 is turned on, the water in the water tank 30 will play a sterilizing role under the action of the UV lamp, which is more conducive to the health of flushing teeth.

[0027] When in use, a thin-wall touch position 11 is provided on one side wall of the shell, which is at a certain distance from the pressure switch 21 on the main control circuit board 20 inside the shell, and is connected in the middle by an elastic body 12. When the user presses the thin-wall touch position 11 hard, the thin-wall touch position 11 is deformed, and the pressure is transmitted to the pressure switch 21 through the elastic body 12 in the middle. After the pressure sensor in the pressure switch 21 senses the pressure change, the sensed pressure change is transmitted to the main control circuit board 20 to adjust the speed of the motor 50, thereby realizing the automatic adjustment effect of the pressure of the water flow, and the elastic body 12 is fed back to the pressure switch 21 to realize the control of the magnitude of the water flow of the water flusher. The operation is simple and convenient, and meets the user's use needs.

[0028] When the water pump 32 is working, the motor 50 drives the eccentric gear 51 to rotate, and the eccentric gear 51 drives the top of the connecting rod 52 to move downward. The connecting rod 52 is connected to the undercut hole 332 of the elastic seal through the undercut boss 53. The elastic seal can be stretched downward and compressed upward under the action of the connecting rod 52; when the elastic seal is stretched downward, the one-way water inlet valve 42 of the water inlet pipe 44 is opened due to the negative pressure. At the same time, the one-way water outlet valve 41 of the water outlet pipe 45 remains in a closed state to prevent water from flowing out at this stage, and negative pressure is formed in the pump body. The water in the water tank 30 of the water flosser enters the water storage chamber 43 of the pump body under the action of the negative pressure. When the elastic seal is stretched downward to the bottom, it turns into a compressed state and opens. When it starts to rebound and compress, the one-way water inlet valve 42 is automatically closed under the action of elastic force, cutting off the water inlet. The compression force causes the one-way water outlet valve 41 to open under pressure, and the water in the pump body is sprayed out from the water outlet nozzle 31 through the water outlet pipe 45 under high pressure. When the elastic seal reaches the upper apex, it enters the next water absorption process, and this cycle is repeated. The water pump 32 can continuously pump out high-pressure water flow. The advantage over the traditional piston pump is that the circular elastomer 12 is an elastic structure, and the motor 50 drives the eccentric gear 51 to drive the connecting rod 52 to compress the elastic seal to generate high-pressure water flow, which has stable operation and avoids the problems of wear and liquid leakage that occur when the traditional piston pump works, thereby improving the service life of the water flosser.

[0029] It should be noted that the elastic body 12 in this embodiment may also be made of other elastic materials such as rubber and TPE.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made to the above embodiment based on the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
