[0031] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0032] Please refer to Figures 1-6 This utility model provides a range hood, including a housing 3, a switch assembly 1, and a connecting structure 2. The switch assembly 1 includes a switch housing 11 and a switch body 12 disposed within the switch housing 11. Both the left and right ends of the switch housing 11 are provided with snap-fit ​​holes 110. Both the left and right ends of the switch assembly 1 are provided with the connecting structure 2, which includes a base 21 mounted on the housing 3. The base 21 is provided with an elastic snap-fit ​​structure, which can switch between two states under external force: insertion into the snap-fit ​​hole 110 and disengagement from the snap-fit ​​hole 110. When the elastic snap-fit ​​structure is inserted into the snap-fit ​​hole 110, the switch assembly 1 is mounted on the housing 3; when the elastic snap-fit ​​structure is disengaged from the snap-fit ​​hole 110, the switch assembly 1 is detached from the housing 3. This design offers advantages such as simple assembly and disassembly, a simple and compact structure, and good installation stability.

[0033] Optionally, the elastic snap-fit ​​structure includes an elastic element 22 and a ball bearing 23. The end of the elastic element 22 facing away from the snap-fit ​​hole 110 is connected to the base 21. The elastic element 22 can extend or retract in a direction approaching or away from the snap-fit ​​hole 110. The ball bearing 23 is installed at the end of the elastic element 22 near the snap-fit ​​hole 110. The ball bearing 23 can extend into the snap-fit ​​hole 110 under the elastic force of the elastic element 22, realizing the installation of the switch assembly 1 on the connecting structure 2, thereby realizing the installation between the switch assembly 1 and the housing 3. The ball bearing 23 can also be ejected from the snap-fit ​​hole 110 under the action of external force, overcoming the elastic force of the elastic element 22, thereby realizing the disassembly of the switch assembly 1 on the connecting structure 2, and thus realizing the disassembly between the switch assembly 1 and the housing 3.

[0034] Optionally, the elastic snap-fit ​​structure also includes a guide hole 210 formed on the base 21. The guide hole 210 is in the same direction of extension and retraction as the elastic member 22. The elastic member 22 is disposed in the guide hole 210 and can slide along the guide hole 210, thereby guiding the elastic member 22 and preventing the elastic member 22 from slipping during extension and retraction, thus ensuring that the elastic snap-fit ​​structure and the snap-fit ​​hole 110 can be stably assembled and disassembled.

[0035] Optionally, the elastic snap-fit ​​structure also includes a stud 24, which is threaded to one end of the guide hole 210 away from the snap-fit ​​hole 110. One end of the elastic element 22 away from the snap-fit ​​hole 110 is connected to the stud 24. The elastic element 22 is installed in the guide hole 210 through the stud 24. The structure is simple and compact, and it is convenient to install the elastic element 22.

[0036] Optionally, the elastic snap-fit ​​structure also includes a limiting part 25. The first side of the base 21 is connected to the housing 3, and the limiting part 25 is disposed on the second side of the base 21. The first side of the base 21 and the second side of the base 21 are disposed opposite to each other. The limiting part 25 abuts against the side of the switch housing 11 that is away from the housing 3, thereby limiting the switch assembly 1 between the base 21 and the lower interior, and improving the installation stability of the switch assembly 1 on the housing 3.

[0037] Optionally, the left and right ends of the switch housing 11 are provided with at least two snap-fit ​​holes 110, and the base 21 is provided with at least two elastic snap-fit ​​structures. The elastic snap-fit ​​structures are provided in a one-to-one correspondence with the snap-fit ​​holes 110, thereby further improving the installation stability between the switch assembly 1 and the connection structure 2.

[0038] Optionally, both the connecting structure 2 and the switch assembly 1 are installed on the rear side of the front panel 31 of the housing 3, which serves both an aesthetic purpose and reduces the amount of oil fumes entering the switch assembly 1.

[0039] Optionally, a clearance hole 310 is provided on the front side panel 31, and the switch assembly 1 is located at the clearance hole 310, so that the user can contact the switch body 12 without passing through the front side panel 31, thereby improving the control sensitivity of the switch assembly 1.

[0040] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
