[0027] In view of the problems in the background technology, combined with reference Figures 1 to 3 As shown, the filter device 100 proposed by the utility model is applied to a water flosser 200, comprising:

[0028] A housing 10, the outer surface of which protrudes outward to form a connecting portion 11, wherein the connecting portion 11 is provided with a liquid outlet pipe 111 for connecting to a main unit 201 of the water flosser 200; and

[0029] A shell cover 20, the shell cover 20 covers the shell 10 and forms a filter cavity 30 with the shell 10 for containing filter materials. The shell cover 20 is provided with a liquid inlet 21;

[0030] Wherein, filter screens 40 are disposed at the positions of the liquid outlet pipe 111 and the liquid inlet 21 .

[0031] In this embodiment, the orthographic projection shape of the shell 10 can be elliptical or circular, and the overall shape is a semi-enclosed structure with one end open. A circular or elliptical connecting portion 11 is protruding from the outer surface of the shell 10, and a liquid outlet pipe 111 can be provided at the center of the connecting portion 11, which can be connected to the host 201 after being sleeved with a hose. The shell cover 20 is sealed on the open end of the shell 10, and the shell cover 20 and the shell 10 can be connected and fixed by means of threaded connection, interference fit, bonding, clamping, etc., so that the shell cover 20 and the shell 10 are enclosed to form a filter cavity 30, and the filter cavity 30 can be filled with filter materials, such as activated carbon, particulate filter materials, ion exchange resins, etc. The filter material can further purify the water quality, effectively remove chlorine, organic matter, odor substances, hardness ions, etc. in the water, improve the water quality and taste, and make oral cleaning healthier and safer. Furthermore, a filter net 40 is set at the position of the liquid inlet 21 to preliminarily filter out impurities when the liquid enters the filter device 100. A filter net 40 is set at the position of the liquid outlet pipe 111 to filter out impurities, organic ions, filter materials, etc. generated after the filter cavity 30 is purified, thereby ensuring that the liquid entering the oral cavity is clean and safe.

[0032] Combined with reference Figure 3 As shown, in one embodiment of the present application, the shell cover 20 and the shell body 10 are snap-connected.

[0033] In order to facilitate the replacement of the filter material in the filter cavity 30 and regular cleaning of the filter cavity 30, the shell cover 20 and the shell body 10 can be snap-connected for easy disassembly and installation, or threaded connection, interference fit and other connection methods that are easy to disassemble can be used.

[0034] Combined with reference Figure 1 and Figure 3 As shown, in one embodiment of the present application, a connecting plate 12 is provided at the edge of the shell 10 along the circumference of its inner wall surface, and the connecting plate 12 protrudes from the edge of the shell 10, and the outer wall of the connecting plate 12 is provided with a snap-in groove 121; a plurality of snap-in parts 22 are protruding from the inner wall surface at the edge of the shell cover 20, and when the shell cover 20 and the shell 10 are snap-connected, the snap-in parts 22 are snap-fitted into the snap-in groove 121.

[0035] It can be understood that the edge of the shell 10 can be integrally formed with a connecting plate 12, and the connecting plate 12 is arranged circumferentially along the inner wall of the shell 10. The connecting plate 12 can be a whole plate, or it can be formed by multiple plates arranged at intervals. The edge of the connecting plate 12 protrudes from the edge of the shell 10 to facilitate docking with the shell cover 20. The outer side wall of the protruding part of the connecting plate 12 can be provided with multiple clamping grooves, and the shape of the clamping groove 121 can be semi-arc-shaped, long strip-shaped, etc. In order to make the shell cover 20 and the shell 10 cooperate and connect, multiple clamping members 22 can be protruded from the inner wall at the edge of the shell cover 20, and the position of the clamping member 22 corresponds to the position of the clamping groove 121. When the shell cover 20 and the shell 10 are clamped and connected, the clamping member 22 is clamped in the clamping groove 121, so that the shell cover 20 and the shell 10 are tightly matched to form a stable filter cavity 30.

[0036] Combined with reference Figure 3 As shown, in one embodiment of the present application, an annular retaining ring 50 is sleeved at the connection between the shell cover 20 and the shell 10 .

[0037] In order to seal the connection between the shell cover 20 and the shell 10, an annular retaining ring 50 can be installed at the connection between the shell cover 20 and the shell 10. The material of the annular retaining ring 50 can be metal, or a sealing ring made of rubber, etc., or a combination of the two, with the sealing ring being installed first and then the annular retaining ring 50 made of metal.

[0038] Combined with reference Figure 2 As shown, in one embodiment of the present application, the liquid inlets 21 are circumferentially spaced around the center of the shell cover 20 .

[0039] It can be understood that in order to increase the amount of liquid entering the filter chamber 30 and make the entering liquid enter the filter chamber 30 evenly, the liquid inlet 21 can be set to be distributed at intervals around the center circumference of the shell cover 20, thereby increasing the amount of liquid entering and the uniformity of entry, thereby improving the filtering effect.

[0040] Combined with reference Figure 4 As shown, the utility model also proposes a water flosser 200, which includes a main unit 201, a water tank 202 and a filter device 100.
