[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-7 A new type of countertop water flosser with a filter screen includes a bottom cover 23 and a water tank 11. A main unit housing 17 is installed on the bottom cover 23. A back plate 1 is fixedly installed on the side of the main unit housing 17 by screws 2. A water tank cover 9 is rotatably installed on the upper end of the back plate 1. The back plate 1 is installed on the top of the main unit housing 17 by screws 2. The function of the back plate 1 is to support the water tank cover 9. The water tank cover 9 is rotatably installed on the upper end of the back plate 1, so that the water tank cover 9 can be flipped to open and close the water tank 11.

[0027] The main housing 17 has an installation hole at its upper end, in which a water tank connector 19 is installed. A water tank connector sealing ring 20 is installed between the water tank connector 19 and the inner wall of the installation hole. A filter screen 15 is installed on the upper end of the water tank connector 19. A filter screen cover 18 is pressed on top of the filter screen 15. The upper end of the filter screen cover 18 is raised. A water outlet is opened at the bottom of the water tank 11. A water tank valve 14 is slidably installed in the water outlet. A spring 13 is fitted on the water tank valve 14. The two ends of the spring 13 are fixedly connected to the water tank valve 14 and the water tank 11, respectively. A sealing ring 12 is fitted on the end of the water tank valve 14 located inside the water tank 11. An annular protrusion 31 is fixedly installed on the lower surface of the filter screen cover 18. The protrusion 31 is in contact with the filter screen 15 by compression. The water tank 11 is placed on the main housing 17. The upper end of the filter screen cover 18 is inserted into the water outlet and is in contact with the lower end of the water tank valve 14.

[0028] The filter screen 15 is pressed between the filter screen cover 18 and the water tank connector 19, and the protruding rib 31 squeezes the filter screen 15 into a concave shape, which can effectively prevent the filter screen 15 from falling off when impacted by water flow. When the water tank 11 is placed on the main unit housing 17, the lower end of the water tank valve 14 is inserted into the mounting hole, and the water tank valve 17 is lifted by the filter screen cover 18. At this time, the spring 13 is compressed, the sealing ring 12 is separated from the contact surface of the water tank 11, and the water flows down through the water tank valve 17 and passes through the filter screen 15. The filter screen 15 effectively prevents foreign matter from flowing through the water tank connector 19, thereby filtering impurities in the tap water and avoiding adverse effects on human health.

[0029] The water tank connector sealing ring 20 is installed between the water tank connector 19 and the main unit housing 17 to prevent water from leaking out from the outside of the water tank connector 19 and also to prevent water from leaking out from the outside of the water tank 11.

[0030] The bottom of the bottom cover 23 is fitted with foot pads 24. The bottom cover 23 is fitted with a core assembly 22. The core assembly 22 is fitted with a power supply 8. The main casing 17 is fitted with a pipe box 30. The pipe box 30 is fixedly fitted with a handle base 16. The handle base 16 is snapped with a handle assembly 29. The water pipe end of the handle assembly 29 is fitted onto the water outlet end of the core assembly 22. The main casing 17 is fitted with a wire clamp 21.

[0031] When placing the countertop water flosser, the feet 24 increase the friction between the bottom cover 23 and the tabletop, making it more stable. The transformer 8 is also known as a power supply. One end of the handle assembly 29 can be fitted with various nozzles. The core component of the countertop water flosser is the motor assembly 22. Water flows through the filter screen 15 to the inlet of the motor assembly 22. The motor assembly 22 turns the low-pressure water flow through the power supply 8 and out at the outlet with high pressure. The water flows through the water pipe to the handle assembly 29 and is sprayed out from the nozzle. The push button on the handle controls whether the high-pressure water flow is open or closed.

[0032] The Fire Bull 8, the movement assembly 22, and the handle assembly 29 are all existing technologies and will not be described in detail here.

[0033] A nozzle box 10 is placed on the upper part of the water tank 11. The nozzle box 10 contains a tongue scraper nozzle 25, a periodontal pocket nozzle 26, an orthodontic nozzle 27, and a standard nozzle 28. Multiple types and functions of nozzles can be placed in the nozzle box 10, thereby improving the versatility of the benchtop water flosser.

[0034] A knob base 3 is installed on the main casing 17. A PCB main board 7 is installed on the knob base 3. A decorative panel 4 is installed on the knob base 3. A mode button 5 and a switch knob 6 are installed on the decorative panel 4. Both the mode button 5 and the switch knob 6 are connected to the PCB main board 7. The PCB main board 7 is equipped with a control switch and a potentiometer with a switching function. The PCB main board 7 is electrically connected to the mechanism assembly 22.

[0035] The PCB main board 7 is placed on the knob base 3 and fixed with screw 2. The input terminal of the PCB main board 7 is connected to a 12V power supply, and the output terminal is connected to the motor. The potentiometer with switch has the function of switching and adjusting the output current. The tactile switch controls the motor working mode. The switch knob 6 is fitted on the potentiometer. The mode button 5 is above the tactile switch for easy pressing. The decorative panel 4 is a light guide, and the corresponding mode light can be seen through the decorative panel 4 to indicate the current working mode.

[0036] When using the countertop water flosser, open the water tank cover 9 and take out the nozzle box 10. At this time, you can directly fill the water tank 11 with water, or take out the water tank 11 to get water from the water source. The water tank 11 with water is installed on top of the main unit housing 17. The weight of the water tank 11 causes the filter screen cover 18 to lift the water tank 14 valve. When the main unit is turned on, the water flows through the filter screen 15 to the water inlet of the core assembly 22. The core assembly 22 can pressurize the low-pressure water flow through the transformer 8 and flow out from the water outlet.

[0037] In this invention, the filter screen 15 is pressed between the filter screen cover 18 and the water tank connector 19. When the water tank 11 is placed on the main unit housing 17, the lower end of the water tank valve 14 is inserted into the mounting hole, and the water tank valve 17 is lifted by the filter screen cover 18. At this time, the spring 13 is compressed, the sealing ring 12 is separated from the contact surface of the water tank 11, and the water flows downward through the water tank valve 17 and passes through the filter screen 15. The filter screen 15 effectively prevents foreign matter from flowing through the water tank connector 19, thereby filtering impurities in the tap water and avoiding adverse effects on human health.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
