The host is provided with a locking device 106 for locking the upper cavity, and the bottom cover is provided with a locking structure 616 matched with the locking device. After the upper cavity is screwed in place, the locking structure 616 is engaged with the locking device 106 to prevent the upper cavity from being accidentally disassembled after power-on.

In this embodiment, the bottom cover 602 has the water leakage hole 610 on the lower edge to prevent the liquid from entering between the support frame and the bottom cover due to the height difference of the upper cavity, and the water leakage hole 610 can discharge the residual water in time to prevent the odor from being generated due to the residual water retention in the sealing member fixing device. If the user in the use will go up unexpected trickle of cavity dismantlement back, the residual water also can be through leaking the hole and in time discharging, guarantees that the accessory is clean, guarantees user safety in utilization.

It is understood that the inner side wall of the connecting section can also be vertically arranged; or, the inner side wall of the lower cavity is obliquely arranged, and the oblique direction of the inner side wall of the connecting section is consistent with that of the inner side wall of the lower cavity.

It can be understood that the water leakage hole can also be arranged on the support frame.

Example two

This embodiment differs from the first embodiment in that the seal fixing means is different. In this embodiment, the sealing element fixing device includes a support frame and does not include a bottom cover, and the support frame is screwed onto the upper cavity and clamps and fixes the sealing element between the support frame and the lower port of the upper cavity. The lower end of the support frame is also provided with an upper screwing structure which is connected with the upper screwing structure of the lower cavity. The structure is simplified, the number of accessories is reduced, and the installation and manufacturing cost is reduced.

In addition to the above preferred embodiments, the technical solutions protected by the present invention are not limited to the above embodiments, and it should be noted that a combination of a plurality of technical solutions in any one embodiment and a combination of a technical solution in any one embodiment and a technical solution in one or more other embodiments are within the scope of the present invention. Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
