That is, the upper surface of the base 3 is located above the bottom wall of the deflector hole 16. So configured, when liquid is present in the first chamber 121, liquid flow from the first chamber 121 into the diversion aperture 16 is facilitated, thereby facilitating liquid flow from the first chamber 121 out of the drain 15. It should be noted that, the distance between the surface of the base 3 adjacent to the center of the first chamber 121 and the bottom wall of the deflector hole 16 may be specifically set according to the requirement, so as to better satisfy the practical application.

Alternatively, a side surface of the base 3 of the locking assembly 5 adjacent to the center of the first chamber 121 extends obliquely from the first chamber 121 toward the direction of the flow-guiding hole 16 toward the direction of the second chamber 122. That is, the upper surface of the base 3 extends obliquely downward from right to left. Therefore, the liquid in the first chamber 121 can flow to the diversion hole 16 along the inclined direction of the upper surface of the base 3, so that the liquid can smoothly flow between the first chamber 121 and the diversion hole 16, the liquid is not easy to accumulate in the first chamber 121, the first chamber 121 can be kept in a cleaner state for a long time, and bacterial growth is reduced.

For example, in the example of fig. 1, the right side of the cover 7 is pivotably connected to the top of the body 1. When the cap 7 is separated from the filling port 1411, the filling port 1411 is opened, and the user can fill the liquid into the liquid storage chamber 11. When the cover 7 is fitted at the pouring port 1411, the pouring port 1411 is closed, and the cover 7 is positioned above the drain channel 142. So arranged, the opening and closing operation of the filling port 1411 is simple, facilitating use of the dental rinse 100. In addition, the cover body 7 can play a role in shielding the sewage disposal channel 142, so that a dustproof effect is achieved, and the cleanliness in the sewage disposal channel 142 is improved.

According to some embodiments of the utility model, referring to fig. 1, when the cover 7 closes the pouring spout 1411, a gap is provided between the side of the cover 7 adjacent to the drain 15 and the drain 15. Therefore, when the cover 7 closes the liquid injection port 1411, the drain port 15 is communicated with the drain channel 142 through the gap, and the liquid flowing into the drain channel 142 from the first chamber 121 can still flow to the drain port 15 and flow out of the drain port 15, so that the cover 7 is not easy to influence the drain port 15, can not block the flow of the liquid, and is further beneficial to smoothly discharging the liquid in the drain channel 142 from the drain port 15 and is further beneficial to the normal use of the tooth cleaning device 100. In addition, the cover body 7 can also play a role in shielding the sewage disposal channel 142, so that dust in the sewage disposal channel 142 is reduced, and the cleanliness in the sewage disposal channel 142 is improved.
