[0033] like Figure 1-5 As shown, the utility model provides a smoke hood assembly, including a smoke hood 1 and a glass panel 2 arranged on the outer side of the side plate of the smoke hood 1, a mounting hole 121 is provided on the outer side of the side plate of the smoke hood 1, a claw structure 3 is provided on the glass panel 2, the claw structure 3 includes elastic claws 31 distributed along the circumference of the mounting hole 121, and all the elastic claws 31 pass through the mounting hole 121 and are engaged with the mounting hole 121.

[0034] In the embodiment of the utility model, a plurality of elastic claws 31 are arranged to be distributed along the circumference of the mounting hole 121 so that all the elastic claws 31 can be engaged with the mounting hole 121 in the circumferential direction of the mounting hole 121, thereby increasing the engaging area between the elastic claws 31 and the mounting hole 121 in the circumferential direction of the mounting hole 121, thereby increasing the engaging strength between the elastic claws 31 and the mounting hole 121, and enhancing the assembly strength between the glass panel 2 and the side panel of the smoke hood 1 while achieving easy installation and disassembly between the glass panel 2 and the side panel of the smoke hood 1, thereby increasing the stability of the glass panel 2 on the smoke hood 1.

[0035] The smoke hood 1 assembly of the present application is used for a range hood, and the smoke hood 1 assembly includes a smoke hood 1 and a glass panel 2. A smoke collecting chamber is formed inside the smoke hood 1, and the smoke hood 1 is bent upward at the outer circumference of the smoke collecting chamber to form a side panel of the smoke hood 1; specifically, the glass panel 2 can be installed on the front side panel of the smoke hood 1, and can also be installed on other side panels of the smoke hood 1. The present application takes the installation of the glass panel 2 on the front side panel of the smoke hood 1 as an example, the glass panel 2 covers the front side panel of the smoke hood 1, and covers the front side panel of the smoke hood 1, and the claw structure 3 is provided on the rear side of the glass panel 2, and the claw structure 3 can be fixed to the rear side of the glass panel 2 by means of adhesive or the like.

[0036] In the embodiment of the utility model, the claw structure 3 includes an annular mounting portion 32 which is coaxial with the mounting hole 121. The outer circumference of the mounting portion 32 is bent toward the mounting hole 121 to form a sheet-like elastic claw 31 with a certain extension length. The free ends of all elastic claws 31 form a claw port 33 of adjustable size.

[0037] In the embodiment of the utility model, one end of the elastic claw 31 is connected to the mounting portion 32, and the other end is a free end. The claw port 33 formed by the free ends of all the elastic claws 31 can make the deformation of the elastic claw 31 unrestricted when it is engaged with the mounting hole 121; specifically, the elastic claw 31 is a spring sheet;

[0038] Specifically, a connecting protrusion 34 protruding in the radial direction of the mounting portion 32 is provided at the opening of the mounting portion 32 facing away from the mounting hole 121, and a free end of the connecting protrusion 34 is bent toward the mounting hole 121 to form an elastic claw 31, and a plurality of elastic claws 31 are evenly distributed along the circumference of the mounting hole 121 and arranged in a circle;

[0039] The connecting protrusion 34 is a polygon, for example, an octagon, and is provided with four elastic claws 31, each elastic claw 31 being correspondingly provided on one side of the connecting protrusion 34, and two adjacent elastic claws 31 are spaced apart by one side of the connecting protrusion 34, so that two adjacent elastic claws 31 are spaced apart, providing sufficient space for deformation of the elastic claws 31. Specifically, the elastic claws 31 extend along the front-to-back direction on the connecting protrusion 34.

[0040] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the elastic claw 31 includes a clamping section 311 and a guide section 312 which gradually extend from the mounting portion 32 toward the mounting hole 121 toward the outer periphery and the inner periphery of the mounting portion 32 respectively. The clamping section 311 is arranged between the connecting protrusion 34 and the guide section 312. The clamping section 311 is guided by the guide section 312 to pass through the mounting hole 121 and clamped with the mounting hole 121.

[0041] In the embodiment of the utility model, the guide section 312 guides the clamping section 311 to enter the mounting hole 121 and clamp with the mounting hole 121, thereby improving the accuracy of clamping all the elastic claws 31 with the mounting hole 121;

[0042] A plurality of elastic claws 31 are evenly distributed along the circumference of the mounting hole 121 and are arranged in a circle. All elastic claws 31 form a whole, which is roughly narrow at both ends and wide in the middle. The radial dimension of the widest part of the whole is greater than or equal to the radial dimension of the mounting hole 121. Therefore, it is not only convenient to assemble the whole with the mounting hole 121, but also beneficial to ensure the connection reliability between the claw structure 3 and the front side plate 11 of the smoke hood.

[0043] A bending portion is formed at the connection between the guide section 312 and the clamping section 311, and the widest part of the whole formed by all the elastic claws 31 is located at the bending portion. Through the deformation of all the elastic claws 31, it is easy to insert all the elastic claws 31 into the mounting hole 121 and clamp them in the mounting hole 121, thereby realizing the assembly between the glass panel 2 and the front panel of the smoke hood 1.

[0044] Furthermore, the guide section 312 includes a first guide portion 312a and a second guide portion 312b distributed in a direction from the mounting portion 32 to the mounting hole 121. The size of the first guide portion 312a remains unchanged from the mounting portion 32 to the mounting hole 121, and the size of the second guide portion 312b gradually decreases from the mounting portion 32 to the mounting hole 121, so that the first guide portion 312a with a smaller size in the guide section 312 first contacts the mounting hole 121 to achieve pre-guidance, and then the second guide portion 312b with a larger size in the guide section 312 contacts the mounting hole 121 to achieve full guidance, thereby speeding up the guidance.

[0045] In the embodiment of the utility model, the claw structure 3 includes a mounting seat 35 arranged on the glass panel 2, and the mounting seat 35 is provided with a columnar mounting protrusion 351 protruding toward the mounting hole 121, and the mounting portion 32 is sleeved on the outer periphery of the mounting protrusion 351 through the opening of the mounting portion 32.

[0046] In the embodiment of the utility model, the claw structure 3 is conveniently connected to the glass panel 2 through the mounting seat 35, and the claw structure 3 is conveniently connected to the side panel of the smoke hood 1 through the elastic claw 31. Thus, it is easy to realize the assembly connection between the glass panel 2, the claw structure 3 and the side panel of the smoke hood 1, and the operation is convenient.

[0047] The mounting seat 35 is square. Specifically, the mounting protrusion is arranged on the rear side surface of the mounting seat 35, and the mounting portion 32 is coaxially sleeved on the outer periphery of the mounting protrusion 351, so as to facilitate the installation and disassembly between the mounting portion 32 and the mounting seat 35, and no additional parts are required to fix the mounting portion 32 on the mounting seat 35; the mounting seat 35 can be fixed on the rear side surface of the glass panel 2 by gluing, screwing, etc.

[0048] Furthermore, the mounting portion 32 and the connecting protrusion 34 are both elastic, and a blocking protrusion 352 is provided at the free end of the mounting protrusion 351 and protrudes in the radial direction of the mounting protrusion 351. The mounting portion 32 and the connecting protrusion 34 are clamped between the mounting seat 35 and the blocking protrusion 352, and the opening end surface of the mounting portion 32 facing the mounting hole 121 abuts against the side surface of the blocking protrusion 352 facing away from the mounting hole 121.

[0049] The mounting portion 32, the connecting protrusion 34, the clamping section 311 and the guiding section 312 are integrally formed, and the process is simple and easy to manufacture;

[0050] In order to prevent the mounting part 32 from falling off the mounting protrusion, a blocking protrusion 352 is provided in the free section of the mounting protrusion. The blocking protrusion 352 blocks the mounting part 32 and cooperates with the mounting seat 35 to clamp the mounting part 32 and the connecting protrusion 34, thereby further improving the assembly strength between the mounting part 32 and the mounting seat 35.

[0051] In the embodiment of the utility model, the side plate of the smoke hood 1 is recessed to form a first profile 12 facing away from the glass panel 2, the mounting hole 121 is provided on the recessed bottom of the first profile 12, and the mounting seat 35 and the connecting protrusion 34 extend into the first profile 12;

[0052] A cylindrical extension portion 122 is formed at the mounting hole 121 and protrudes away from the glass panel 2. The extension portion 122 is coaxially arranged with the mounting hole 121 and gradually narrows along its own protruding direction. The mounting protrusion 351 and the blocking protrusion 352 extend into the extension portion 122 through the mounting hole 121. The clamping section 311 and the guiding section 312 pass through the extension portion 122 through the mounting hole 121, and all the clamping sections 311 are engaged with the extension portion 122.

[0053] In the embodiment of the utility model, the front side panel of the smoke hood 1 is recessed backward to form a first profile 12. The first profile 12 can increase the structural strength of the front panel of the smoke hood 1. The recess of the first profile 12 between the smoke hood 1 can accommodate the mounting seat 35 and the connecting part. When the glass panel 2 is assembled on the front side panel of the smoke hood 1 through the claw structure 3, it is beneficial to reduce the gap between the glass panel 2 and the front side panel of the smoke hood 1, which is convenient for installation, stable and beautiful.

[0054] The mounting hole 121 is formed on the concave bottom of the first press profile 12 . The mounting hole 121 passes through the concave bottom of the first press profile 12 . The shape of the mounting hole 121 matches with a plurality of elastic claws 31 . For example, the mounting hole 121 may be in the shape of a square hole, a round hole, etc.

[0055] A plurality of first profiles 12 are provided on the front side panel of the smoke hood 1, and the plurality of first profiles 12 are spaced apart in the left-right direction. Each first profile 12 is provided with a mounting hole 121, and a corresponding claw structure 3 is installed on the mounting hole 121, which can ensure the installation reliability between the glass panel 2 and the front panel of the smoke hood 1.

[0056] The elastic claw 31 can be supported and limited by the extension part 122, and the structure is more reasonable. When clamping, the guide section 312 passes through the extension part 122 through the mounting hole 121 to the outside of the extension part 122, the first part of the clamping part passes through the extension part 122 through the mounting hole 121 to the outside of the extension part 122, and the second part of the clamping part extends into the extension part 122 through the mounting hole 121. The connection between the first part and the second part of the clamping part abuts against the inner periphery of the extension part 122, so that all the elastic claws 31 are matched with the mounting hole 121 for clamping.

[0057] Specifically, the claw structure 3 on the glass panel 2 is inserted into the mounting hole 121 on the front panel of the smoke hood 1. Since the whole formed by all the elastic claws 31 presents a structure that is narrow at both ends and wide in the middle, the radial dimension of the whole at the maximum width is larger than the radial dimension of the mounting hole 121. All the elastic claws 31 are compressed and deformed during the fixing process of the glass panel 2. When the bending portion on the elastic claws 31 passes through the extension portion 122, all the elastic claws 31 begin to recover. After the glass panel 2 is fixed in place, the clamping portion contacts the extension portion 122. The width of the whole formed by all the elastic claws 31 at the contact point is smaller than the width of the whole formed by all the elastic claws 31 in the free state at this position. At this time, the whole formed by the elastic claws 31 is still in a contracted state, and tends to move backward to restore the free state, giving a fastening force between the glass panel 2 and the front panel of the smoke hood 1, thereby achieving fixation between the two.

[0058] like Figure 6 As shown, in the embodiment of the utility model, the glass panel 2 is arranged on the outer side of the front side plate 11 of the smoke hood, the left side plate and the right side plate of the smoke hood 1 are respectively bent toward the front side plate to form a folded edge 14, and the front side plate 11 of the smoke hood is provided with a second pressed profile 13 which is recessed away from the glass panel 2, and the folded edge 14 is fitted with the recessed bottom of the second pressed profile 13 and riveted.

[0059] In the embodiment of the utility model, the folded edge 14 on the left side of the smoke hood 1 is folded from the plane of the left side plate of the smoke hood 1 to the front side plate, and is fitted with the concave bottom of a second press profile 13 on the front side plate, and is riveted. The folded edge 14 on the right side of the smoke hood 1 is folded from the plane of the right side plate of the smoke hood 1 to the front side plate, and is fitted with the concave bottom of another second press profile 13 on the front side plate, and is riveted. The two folded edges 14 are flush with the front panel of the smoke hood 1. The above arrangement can improve the sealing of the entire smoke hood 1

[0060] Sex and aesthetics.

[0061] A plurality of first profiles 12 are distributed along the left and right directions on the smoke hood 1 , forming an assembly area. Two second profiles 13 are arranged on the left and right sides of the assembly area and are located at the left and right ends of the front panel of the smoke hood 1 .

[0062] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
