[0024] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0025] Combination Figures 1-6 As shown, the split-type range hood includes a separately designed fan assembly 1 and a smoke inlet assembly 2 connected below the fan assembly 1. The smoke inlet assembly 2 has a vertically extending smoke inlet chamber 21. Inside the fan assembly 1, there is a smoke collection chamber 12 that is vertically connected to the smoke inlet chamber 21, an installation chamber 13 located in front of the smoke collection chamber 12, and a fan (not shown) fixed in the installation chamber 13. The air intake of the fan is connected to the smoke collection chamber 12, and the air exhaust of the fan is located on the outer side of the fan assembly 1. The air guide hood (not shown in the figure) connects the air exhaust of the fan to a pre-set smoke exhaust channel in the environment.

[0026] This invention improves the disassembly and assembly structure between the smoke inlet assembly 2 and the fan assembly 1, allowing the smoke inlet assembly 2 to be installed or disassembled and maintained more conveniently relative to the fan assembly 1 using the disassembly and assembly structure, making it easy to operate and convenient to use.

[0027] Specifically, the disassembly and assembly structure between the smoke inlet assembly 2 and the fan assembly 1 includes: multiple hooks 15 and vertically movable pins 17 are provided on the bottom surface of the fan assembly 1, and the openings of the multiple hooks 15 are all arranged facing forward; multiple hanging slots 23 and vertically arranged fixing holes 24 are provided on the top surface of the smoke inlet assembly 2; each hook 15 is engaged with one of the corresponding hanging slots 23 to provide vertical limitation when the smoke inlet assembly 2 is fixed below the fan assembly 1, and the pin 17 is inserted downward into the fixing hole 24 to provide lateral limitation when the smoke inlet assembly 2 is fixed below the fan assembly 1.

[0028] In order to ensure that the smoke inlet assembly 2 can be securely installed below the fan assembly 1, a disassembly and assembly structure is usually provided between the two sides of the bottom surface of the fan assembly 1 and the two sides of the top surface of the smoke inlet assembly 2.

[0029] In addition, when the smoke inlet assembly 2 is fixed below the fan assembly 1, the back side of the smoke inlet assembly 2 is vertically aligned with the back side of the fan assembly 1, which makes the assembled range hood occupy less space and more convenient for users.

[0030] A reinforcing base plate 14 is provided on the inner bottom of the fan assembly 1, and multiple hooks 15 are fixed to the bottom side of the reinforcing base plate 14. After the smoke inlet assembly 2 is installed on the bottom surface of the fan assembly 1, the weight of the smoke inlet assembly 2 is applied to the reinforcing base plate 14 through the multiple hooks 15. The reinforcing base plate 14 distributes the weight of the smoke inlet assembly 2 to the bottom surface of the fan assembly 1, thereby enhancing the structural strength of the bottom surface of the fan assembly 1 and ensuring that the disassembly and assembly structure between the smoke inlet assembly 2 and the fan assembly 1 is firm and durable.

[0031] Similarly, a reinforcing top plate 22 is fixed on the inner top surface of the smoke inlet assembly 2, and a hook 15 extends into the hanging groove 23 and is connected to the reinforcing top plate 22. The reinforcing top plate 22 is used to improve the structural strength of the top surface of the smoke inlet assembly 2, ensuring that the disassembly and assembly structure between the smoke inlet assembly 2 and the fan assembly 1 is firm and durable.

[0032] Additionally, to facilitate the insertion of the hook 15 into the corresponding hanging slot 23, such as Figure 6 As shown, the rear end of the hanging groove 23 is configured as a groove inlet end 231 for easy insertion of the hook 15, and the front end of the hanging groove 23 is configured as a groove limiting end 232 for limiting and holding the hook 15. The groove width of the groove inlet end 231 is greater than the groove width of the groove limiting end 232.

[0033] To ensure that the pin 17 can move vertically and accurately engage with the fixing hole 24, a pin seat 16 is provided on the bottom surface of the fan assembly 1. The pin 17 is vertically movable and is located in the pin seat 16. The pin 17 moves vertically according to the pin seat 16, so that the pin 17 is located directly above the fixing hole 24, so that the pin 17 and the fixing hole 24 maintain a reliable engagement relationship.

[0034] Furthermore, a spring 18 is provided between the pin seat 16 and the top of the pin 17. The spring 18 is used to generate a downward elastic force on the pin 17, so that the lower end of the pin 17 is kept inserted in the fixing hole 24 by the downward elastic force, preventing the pin 17 from coming out of the fixing hole 24. Therefore, the smoke inlet assembly 2 is locked below the fan assembly 1 by inserting the pin 17 into the fixing hole 24.

[0035] Since the smoke inlet assembly 2 needs to be installed below the fan assembly 1 or removed from the fan assembly 1, the operator needs to manually operate the pin 17. To facilitate operation, an operating handle 171 is provided at the upper end of the pin 17. The operator can operate the pin 17 to move vertically upward or downward within the pin seat 16 by operating the operating handle 171.

[0036] To prevent the operating handle 171 from being contaminated by the oil fumes passing through the smoke collection chamber 12, the operating handle 171 is located inside the mounting chamber 13. Specifically, the pin seat 16 is located inside the mounting chamber 13 and fixed to the inner partition 11. Of course, the front panel or the side panels of the fan assembly 1 are designed to be openable or detachable relative to the mounting chamber 13. By opening the front panel or side panels to expose the mounting chamber 13, it is not only convenient to operate the pin 17, but also convenient to operate when inspecting and maintaining components such as circuit boards inside the mounting chamber 13.

[0037] Range hoods are typically used in the kitchen and installed above the cooking stove. In particular, to ensure that the range hood does not obstruct the user's cooking operations, it is usually installed on the wall or cabinet wall next to the stove.

[0038] Taking the installation of a range hood on the wall next to the stove as an example, the specific installation process is as follows:

[0039] First, the back panel of the fan assembly 1 is fixedly installed on the wall using any of the following methods: mounting holes, brackets, screws, etc. At this time, the back panel of the fan assembly 1 is close to or even flush with the wall.

[0040] Next, the operator holds the smoke inlet assembly 2 with both hands and moves it below the fan assembly 1, so that the multiple hooks 15 on the bottom surface of the fan assembly 1 are aligned with one of the hanging slots 23 on the top surface of the smoke inlet assembly 2, and the hooks 15 are inserted from the slot entrance end 231 of the hanging slot 23; at the same time, the operator moves the pin 17 upward through the operating handle 171 so that the pin 17 is dislodged from the fixing hole 24.

[0041] Finally, push the smoke inlet assembly 2 horizontally backward toward the wall, so that the hook 15 moves from the groove inlet end 231 at the rear end of the hanging groove 23 to the groove limiting end 232 at the front end of the hanging groove 23, and the hook 15 is hooked on the groove wall in front of the groove limiting end 232, thereby vertically limiting the smoke inlet assembly 2 to the bottom of the fan assembly 1; at this time, the pin 17 is aligned with the fixing hole 24, and the pin 17 is inserted into the fixing hole 24 under the downward elastic force generated by the spring 18. Through the cooperation of the pin 17 and the fixing hole 24, the smoke inlet assembly 2 is limited to the bottom of the fan assembly 1, providing a horizontal limiting lock, and the installation of the range hood is completed.

[0042] Therefore, it can be seen that the range hood of this utility model can be easily and completely installed by only one operator, and the installation operation is very simple.

[0043] In addition, when it is necessary to remove the smoke inlet assembly 2 for cleaning and maintenance, simply follow the reverse steps of the installation process.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
