[0034] 1 and 2 , the sterilization and deodorization device of the first embodiment of the present application includes: a shell 100, which is provided with a water tank 120; a controller 400, which is arranged in the shell 100; an ion generator, which is arranged in the shell 100, and includes a connecting terminal 211 and a silver rod 212, the silver rod 212 is electrically connected to the controller 400 through the connecting terminal 211, and the silver rod 212 extends into the water tank 120; a radical generator 221, which is arranged in the shell 100, and the radical generator 221 is electrically connected to the controller 400, and a part of the radical generator 221 extends into the water tank 120, and the radical generator 221 is used to generate free radicals; and a sprayer, which is used to spray the water in the water tank 120 to the outside of the shell 100.

[0035] The controller 400 is provided with a battery, and the silver rod 212 is electrically connected to the controller 400 through the connecting terminal 211. The controller 400 controls the conduction or disconnection between the battery and the silver rod 212. By adding water into the water tank 120, the controller 400 then energizes the silver rod 212 to generate silver ions in the water in the water tank 120. Then, radicals such as hydroxyl free radicals are generated in the water through the radical generator 221, so that the water in the water tank 120 becomes a purifier with sterilization and deodorization functions. Finally, the purifier containing silver ions and radicals is sprayed onto the garbage through the sprayer, so that the silver ions and radicals cooperate to achieve sterilization and deodorization, thereby preventing odor from polluting the environment.

[0036] It can be understood that, referring to FIG2 , the sprayer includes a cotton swab holder 310, a cotton swab 320, and an atomizing sheet 330. The cotton swab 320 is disposed in the cotton swab holder 310, with one end of the cotton swab 320 extending into the water tank 120, and the other end of the cotton swab 320 abutting against the atomizing sheet 330. The cotton swab 320 extends into the water tank 120, absorbs the purifier in the water tank 120, and then is atomized by the atomizing sheet 330 and sprayed into the trash can. This saves purifier while atomizing the purifier to expand the spraying area, enhance the purifier's penetration into the trash, and improve the sterilization and deodorization effect. At the same time, the cotton swab holder 310 wraps the cotton swab 320, secures the cotton swab 320, and prevents the cotton swab 320 from softening and falling into the water tank 120 after absorbing water.

[0037] 2 , the end of the cotton swab 320 extending into the water tank 120 abuts against the bottom of the water tank 120 . Even if the water level in the water tank 120 drops, the cotton swab 320 can completely absorb the purifier in the water tank 120 , thereby improving the utilization rate of the purifier.

[0038] It can be understood that, referring to Figure 2, the radical generator 221 includes an ultraviolet lamp, the light-emitting end of the ultraviolet lamp extends into the water tank 120, and the ultraviolet lamp is electrically connected to the controller 400. By extending the light-emitting end of the ultraviolet lamp into the water, the ultraviolet rays generated by the ultraviolet lamp irradiate the water body, causing the water body to decompose radicals such as hydroxyl free radicals, which cooperate with silver ions to improve the sterilization and deodorization effect.

[0039] It can be understood that, referring to Figures 1 and 3, the housing 100 is provided with a cover 110, which covers the upper side of the water tank 120. A locking assembly 230 is provided between the cover 110 and the water tank 120, and the cover 110 and the water tank 120 are fixedly connected by the locking assembly 230. The cover 110 and the water tank 120 cooperate to form an installation space, and the ion generator, the radical generator 221 and the sprayer are all arranged in the installation space and are all connected to the cover 110, so that the water tank 120 can be easily removed to replenish water. The locking assembly 230 makes the cover 110 and the water tank 120 detachable, which is convenient and practical.

[0040] As can be understood, referring to FIG. 2 , the upper end of the water tank 120 is open, and a positioning portion 121 is formed protruding from the upper end of the water tank 120. The cover 110 is provided with a positioning groove 111 that matches the positioning portion 121, and the positioning portion 121 is plugged into the positioning groove 111. The plugging and mating of the positioning groove 111 and the positioning portion 121 allows the cover 110 and the water tank 120 to be quickly connected, which is convenient and practical, while also improving the sealing between the cover 110 and the water tank 120 and preventing water leakage in the water tank 120.

[0041] It will be understood that, referring to Figure 3, the locking assembly 230 includes two sets of locking units, which are symmetrically arranged and cooperate to lock the cover 110 and the water tank 120. Specifically, the locking unit includes a rotating block 231 and a limiting block 232. The rotating block 231 is hinged to the outer wall of the water tank 120, and the limiting block 232 is arranged on the outer wall of the cover 110. The rotating block 231 has a snap-fitting groove 234, and the limiting block 232 has a snap-fitting portion 233 that matches the snap-fitting groove 234. When the rotating block 231 rotates, the limiting block 232 enters the snap-fitting groove 234, so that the snap-fitting portion 233 snaps into the rotating block 231. The engaging groove 234 extends along the circumference of the rotating block 231, and both ends of the engaging groove 234 are open. By rotating the rotating block 231, the limiting block 232 is moved into the engaging groove 234, so that the engaging portion 233 is engaged with the rotating block 231. The engaging groove 234 limits the radial and axial movement of the engaging portion 233 along the rotating block 231, so that the cover body 110 and the water tank 120 are stably combined together. When the cover body 110 needs to be separated from the water tank 120, when adding water to the water tank 120, the rotating block 231 is rotated to separate the limiting block 232 from the engaging groove 234, so that the cover body 110 and the water tank 120 can be separated, which is convenient and quick.

[0042] Referring to FIG4 , a second embodiment of the present application includes a trash can comprising the sterilization and deodorization device of the first embodiment of the present application, with a sprayer communicating with the interior of the trash can. Silver rod 212 is energized to generate silver ions in the water within water tank 120. A radical generator 221 then generates radicals such as hydroxyl radicals in the water. A purifier containing the silver ions and radicals is then sprayed into the trash can via the sprayer, achieving sterilization and deodorization, thereby preventing odor from polluting the environment.

[0043] As can be understood, referring to FIG5 , the trash can includes a barrel body 500, an outer wall of which is provided with a hanger 510, which is provided with a support plate 511 and a hanging hole 513. The housing 100 is provided with a hook 130, which is engaged with the hanging hole 513. The support plate 511 is used to support the water tank 120. The hook hole 513 is engaged with the hook 130, which facilitates the installation of the sterilization and deodorization device on the trash can and also facilitates disassembly, improving convenience. The support plate 511 is provided to support the water tank 120, preventing the sterilization and deodorization device from falling when the trash can is shaken or moved, thereby improving the connection stability. In addition, the barrel body 500 is provided with a through hole 512 that communicates with the interior of the barrel body 500. When the hanger 510 is engaged with the hanging hole 513, the water outlet of the sprayer docks with the through hole 512, allowing the sprayer to directly inject the deodorizing liquid into the barrel body.
