A side surface of the water tank 30 close to the first housing 10 may be an inner wall of the water tank 30, and correspondingly, a side surface of the water tank 30 far from the first housing 10 may be an outer wall of the water tank 30. In an embodiment, the outer wall of the water tank 30 may be in pressing contact with the wiper strip 411 in the soil cleaning assembly 40.

In some embodiments, the main unit 100 further includes a second sealing ring 52, and the second sealing ring 52 can be used for sealing connection between the water tank 30 and the first housing 10 to prevent the cleaning liquid in the water tank 30 from entering the insertion groove 101, and further prevent the cleaning liquid from entering the interior of the first housing 10 through the insertion groove 101 and the assembly gap between the first housing 10 and the second housing 20. Thereby, the waterproof protection of the inside of the first casing 10 can be further improved.

As shown in fig. 7 and 8, in some embodiments, the second sealing ring 52 may be disposed around the circumference of the first casing 10 and near the open end 1011 of the insertion groove 101. An annular avoidance groove 302 is formed in the inner wall of the water tank 30, namely the avoidance groove 302 is circumferentially arranged around the water tank 30. Meanwhile, the inner wall of the water tank 30 is further provided with a flange 31 protruding relative to the avoiding groove 302, and the flange 31 may also be arranged in a circle around the circumference of the water tank 30.

In an embodiment, the flange 31 is located at an end of the avoidance groove 302 near the opening structure 301. The flange 31 may be provided with a shorter length along the axial direction of the dental irrigator main body 100, and the avoiding groove 302 may extend from one side of the flange 31 to one end of the closed structure of the water tank 30, i.e., the length of the flange 31 is far less than that of the avoiding groove 302. The axial direction of the tooth irrigator main body 100 may refer to the extending direction of the axial line L.

Referring to fig. 9, on any cross section parallel to the axis L and passing through the axis L, the diameter n of the bypass groove 302 corresponding to a side wall of the first housing 10 is set₂And may be larger than the corresponding outer diameter n of the second seal ring 52₁Meanwhile, a diameter n of the flange 31 corresponding to a side wall of the first housing 10 is set₃May be smaller than the corresponding outer diameter n of the second seal ring 52₁. Wherein, the outer diameter n corresponding to the second seal ring 52₁This may refer to the outer diameter of the second seal ring 52 when not radially compressed.

As shown in fig. 3 to 6, when the water tank 30 is switched between the storage state 30a and the extended state 30b, a gap may be formed between the second sealing ring 52 and a side wall of the avoiding groove 302 opposite to the first casing 10, that is, the side wall of the avoiding groove 302 opposite to the first casing 10 is not in contact with the second sealing ring 52.

When the water tank 30 is switched to the extended state 30b for use, the flange 31 can be abutted against the second sealing ring 52, that is, the second sealing ring 52 is compressed and disposed between the flange 31 and the first housing 10, so as to achieve the sealing connection between the inner wall of the water tank 30 and the first housing 10. When the cleaning liquid is injected into the water tank 30, the probability that the cleaning liquid in the water tank 30 enters the insertion groove 101 is also reduced, and the possibility that the cleaning liquid enters the first housing 10 is further reduced.

It will be appreciated that during the switching of the water tank 30 between the stored condition 30a and the extended condition 30b, only the portion of the flange 31 of the water tank 30 will exert a friction effect on the second gasket 52. Therefore, the friction stroke of the water tank 30 to the second sealing ring 52 can be shortened, the abrasion of the second sealing ring 52 is delayed, the service life of the second sealing ring 52 is prolonged, and the sealing performance between the water tank 30 and the first shell 10 is ensured when the tooth flusher is used.

Further, in some embodiments, the flange 31 may be a separate structure from the tank 30, and the flange 31 may be removably coupled to the tank 30. In one embodiment, the flange 31 may be made of silicone, rubber, or plastic. When the flange 31 and/or the second sealing ring 52 are worn, the flange 31 can be replaced to ensure the sealing performance of the first housing 10 and the inner wall of the water tank 30. It will be appreciated that when the second seal ring 52 is worn, the flange 31 may be replaced with a more protruding structure with respect to the escape groove 302 to compensate for the size of the second seal ring 52. In one embodiment, the flange 31 may be removably attached to the tank 30 by interference fit or the like.

In other embodiments, the second sealing ring 52 can be replaced to ensure the sealing connection between the first housing 10 and the inner wall of the water tank 30.

In other embodiments, the inner wall of the water tank 30 may be provided with a smooth curved surface. When the water tank 30 is switched between the storage state 30a and the extended state 30b, the water tank 30 can be in full-stroke press-contact with the second seal ring 52.
