In the specific embodiment, the cover 41 is mainly composed of a first cover body 411 and a second cover body 412, which are integrated into a single structure, wherein the first cover body 411 is in an arch shape with the edge gradually protruding towards the center so as to install the functional component 42, the second cover body 412 is connected to the rear end of the first cover body 411, and the diameter of the second cover body 412 is smaller than that of the first cover body 411, the second cover body 412 is mainly used for accommodating and installing the functional shell 421, with a recess 413 arranged in the middle, so that, in actual use, when the functional element 42 is located in the installation chamber 4, and when the cover 41 is sealed and installed in the cavity 4, the second cover body 412 is sleeved on the front end of the functional shell 421, therefore, on one hand, the user pushes the functional element 42 by the cover 41 through the force applied to the cover 41, and on the other hand, the displacement of the functional element 42 when the piercing member 123 pierces the functional element 42 is avoided, so that the functional element 42 is supported and fixed.

As another embodiment of the present invention, the cover 41 is further provided with a connecting member 43 connected to the mounting body 1211, the connecting member 43 is mainly used for connecting the cover 41, so that the cover 41 is not completely detached from the tooth irrigator, and the cover 41 is still connected to the mounting structure 102 through the connecting member 43, thereby providing convenience in use and avoiding the loss of the cover 41. In a specific embodiment, the connection member 43 includes a connection ring 431 sleeved on the periphery of the first cover body 411 and a connection member 432 located at the edge of the connection ring 431, a connection channel 1213 for the connection member 432 to pass through and/or move is provided on the first installation body 1211, in this embodiment, the connection member 43 mainly includes the connection ring 431 and the connection member 432, both of which are integrated into a whole, wherein the connection ring 431 is sleeved on the periphery of the first cover body 411, the connection member 432 is fixedly connected to the edge of the connection ring 431, the connection member 432 is disposed toward the first installation body 1211, the first installation body 1211 is provided with the connection channel 1213 matched with the connection member 432, and the connection member 432 can pass through the connection channel 1213 and can move back and forth relative to the connection channel 1213 without being fixedly connected, so that the connection of the cover body 41 is flexible. In other embodiments, the connecting member 432 includes a connecting rod 4321 connected to the connecting ring 431 at one end, a connecting head 4322 connected to the other end of the connecting rod 4321, the connecting head 4322 is located in the hollow chamber, and can be abutted against the rear end face of the first installation body 1211, the diameter of the connecting channel 1213 is greater than or equal to the connecting rod 4321, the diameter of the connecting channel 1213 is less than or equal to the connecting head 4322, in the specific embodiment, the connecting member 432 is mainly composed of a connecting rod 4321 and a connecting head 4322, wherein the connecting head 4322 is fixedly connected with the rear end of the connecting rod 4321, and the cross-sectional diameter of the connecting head 4322 gradually increases from the rear end to the front end, for which purpose the connecting head 4322 can pass through the connecting channel 1213 from front to back, but cannot pass through the connection passage 1213 from the rear to the front, and for this reason when the connection rod 4321 is moved, the connector 4322 has a limiting function, prevents the connector 432 from being separated from the connecting channel 1213, and has a simple structure and good stability.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.

In summary, the above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the claims of the present invention.
