Therefore, they cannot be understood as limitations on the present invention. The terms "connected", "connected" and "set" used in the present invention should be understood in a broad sense, for example, they can be fixedly connected or detachably connected; they can be directly connected or indirectly connected through an intermediate component; they can be wired electrical connections, radio connections, or wireless communication signal connections. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0039] like Figure 1 , Figure 2 , Figure 5-Figure 7 As shown, the embodiment of the utility model provides an installation structure of an oil net and a fume hood, including a retaining spring 1 and a mounting hole 2, which are respectively arranged on the oil net 3 and the fume hood 4. In order to facilitate the installation and removal of the retaining spring 1, in this embodiment, the retaining spring 1 is arranged on the oil net 3, and the mounting hole 2 is arranged on the fume hood 4, but it is not limited to this. And for the convenience of explanation, the installation direction of the oil net 3 is defined as upward (i.e. Figure 5 The disassembly direction of the oil screen 3 is downward (i.e. Figure 5 ).

[0040] Specifically, if Figure 3 , Figure 4 As shown, the retaining spring 1 includes a fixing plate 11 and a plurality of elastic retaining plates 12. The fixing plate 1 is fixedly connected to the oil net 3, for example, by means of clamping, etc., so as to fix the retaining spring 1 to the oil net 3. The retaining plate 12 includes a first section 121 and a second section 122 that are connected to each other. The first section 121 extends obliquely upward from the top surface of the fixing plate 11 in a direction away from the center of the fixing plate 11, and the second section 122 extends obliquely upward from the top end of the first section 121 in a direction toward the center of the fixing plate 11. The projections of the bottom end of the first section 121 and the top end of the second section 122 in the axial direction of the mounting hole 2 correspond to the inner side of the mounting hole 2, and the projections of the top end of the first section 121 (i.e., the bottom end of the second section 122) in the axial direction of the mounting hole 2 correspond to the outer side of the mounting hole 2.

[0041] The installation structure of the oil net and the smoke hood provided by the embodiment of the utility model can smoothly insert the oil net 3 upward into the smoke hood 4 because the ends (top ends) of the second sections 122 of each clip 12 of the clip 1 correspond to the inner side of the mounting hole 2 during the process of installing the oil net 3 into the smoke hood 4. During the upward insertion process, because the bottom end of the second section 122 corresponds to the outer side of the mounting hole 2, the inner wall of the mounting hole 2 generates an inward force on the clip 12, compressing the clip 12 inward until the oil net 3 is installed in place. At this time, the first section 121 of the clip 12 abuts against the top end of the mounting hole 2, the mounting hole 2 no longer compresses the clip 12 inward, and the top end of the first section 121 is reset to correspond to the outer side of the mounting hole 2 again, thereby limiting the clip 1 from being detached from the mounting hole 2. In this way, the installation structure of the oil net and the smoke hood provided by the embodiment of the utility model, compared with the current installation structure of the oil net and the smoke hood, changes the matching structure of the male lock buckle and the female lock buckle into a retaining spring 1 and a mounting hole 2 structure, eliminates the gluing and screw connections, reduces the number of parts, improves the assembly efficiency, and enhances the connection quality.

[0042] Furthermore, the mounting hole 2 may be a circular hole, a cylindrical hole, a square hole or a square cylinder. Accordingly, the arrangement of the clamping plates 12 on the fixing plate 11 also forms a circular or square shape. Figure 2 As shown, in this embodiment, the mounting hole 2 is a cylinder to improve the connection stability between the clamping plate 12 and the mounting hole 2. In order to further improve the connection stability between the clamping plate 12 and the mounting hole 2, the clamping plate 12 is symmetrically arranged at the edge of the fixing plate 11.

[0043] In a preferred embodiment of the present invention, the fixing plate 11 is connected to the oil screen 3 by a snap connection. Figure 4 , Figure 8 As shown, the fixing plate 11 is provided with a first fixing hole 111, and the oil net 3 is fixed with a mounting plate 31 to form a flange. The mounting plate 31 is provided with a second fixing hole 311 corresponding to the first fixing hole 111. The first fixing hole 111 and the second fixing hole 311 are provided with fixing members to fix the fixing plate 11 to the mounting plate 31 of the oil net 3. The fixing member avoids using parts such as bolts or screws to reduce the difficulty of operation. Therefore, in this embodiment, the fixing member is a buckle 5.

[0044] Specifically, if Figure 9-13 As shown, the buckle 5 includes an operating terminal 51, and a plurality of elastic clamping feet 52 are provided on the bottom surface of the operating terminal 51. The operating terminal 51 abuts against the top surface of the fixing plate 11, and the clamping feet 52 abut against the bottom surface of the mounting plate 31, and the two clamp the fixing plate 11 and the mounting plate 31 in the middle. Specifically, a groove 521 is provided at one end of the clamping foot 52 close to the operating terminal 51, and the mounting plate 31 and the fixing plate 11 are clamped in the groove 521. In order to facilitate the insertion of the clamping foot 52 into the first fixing hole 111 and the second fixing hole 311, the clamping foot 52 has a guiding inclined surface 522, and the guiding inclined surface 522 extends inwardly in a direction away from the operating terminal 51. During installation, the first fixing hole 111 on the fixing plate 11 is aligned with the second fixing hole 311 on the mounting plate 31, and then the buckle 5 is pressed in to complete the installation, which greatly improves the assembly efficiency. Due to the presence of the clamping plate 12, interference may occur when pressing the buckle 5. In order to solve this problem, a rod-shaped tool such as a screwdriver can be used to press and install the buckle 5. At this time, the top surface of the operating end 51 is provided with a cross-shaped groove 53, which can cooperate with the cross-shaped ridge of the screwdriver to prevent the screwdriver from sliding.

[0045] The oil screen 3 and the smoke hood 4 can be completely installed through the clamping spring 1 and the mounting hole 2 of the utility model, that is, multiple clamping springs 1 and mounting holes 2 are provided. Of course, in order to reduce parts and reduce production costs, the number of clamping springs 1 and mounting holes 2 can be as small as possible. For example, Figure 8 , Fig. 9 As shown, a hook 32 is provided on one side of the oil net 3, and the clip 1 is provided on the other side of the oil net 3. The smoke hood 4 is provided with a hanging hole 41 corresponding to the hook 32. When installing, the hook 32 of the oil net 3 is hung in the hanging hole 41 on the smoke hood 4, so that one side of the hook 32 is rotatably connected to the smoke hood 4, and then one or two clips 1 on the other side of the oil net 3 are inserted upward into the mounting hole 2 on the smoke hood 4 to complete the installation.

[0046] In an embodiment of the present invention, the clamping spring 1 is made of stainless steel, and the number of the clamping plates 12 is four, but not limited thereto.

[0047] The utility model also provides a range hood, including the above-mentioned installation structure of the oil net and the smoke hood. When installing the smoke hood and the oil net, there is no need to use screws to fix them or to glue them, so the installation is convenient, the number of parts is reduced, and the overall assembly efficiency is improved.

[0048] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
