In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0057] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0058] Please refer to Figures 1 to 6The embodiment of the present invention provides a range hood, comprising a frame 20, a box shock-absorbing structure 10 and a fan assembly 30. The fan assembly 30 is connected to the box shock-absorbing structure 10 and the frame 20. When the fan assembly 30 is in operation, it will drive the box shock-absorbing structure 10 and the frame 20 to vibrate. The box shock-absorbing structure 10 comprises a first mounting plate 110, a second mounting plate 120 and a support assembly 130. The first mounting plate 110 is connected to the frame 20, the second mounting plate 120 is connected to the first mounting plate 110, and the angle between the first mounting plate 110 and the second mounting plate 120 forms an installation space 140, and the fan assembly 30 is located in the installation space 140. The two ends of the support assembly 130 are respectively connected to the first mounting plate 110 and the second mounting plate 120, which are away from the opposite sides of the installation space 140.

[0059] Please continue to refer to Figure 3 In one embodiment of the present invention, the fan assembly 30 includes a motor and a wind wheel. The output shaft of the motor is vertically arranged with the second mounting plate 120. The motor is connected to the wind wheel. The wind wheel swings with the drive of the motor. The fan system formed by the wind wheel during the swinging process will generate centrifugal force. The wind wheel rotates, and the centrifugal force will impact the fan system once. As the speed of the wind wheel rotation increases, the centrifugal force will increase, and then the impact on the first mounting plate 110 and the second mounting plate 120 will increase, thereby causing the first mounting plate 110 and the second mounting plate 120 to shake. The setting of the support assembly 130 can enhance the connection stability between the first mounting plate 110 and the second mounting plate 120, thereby reducing the vibration intensity of the fan assembly 30 on the first mounting plate 110 and the second mounting plate 120. Furthermore, in order to ensure the lightweight of the entire machine, a plurality of weight-reducing holes 160 are provided on the first mounting plate 110 and the second mounting plate 120. The more weight-reducing holes 160 are provided, the lighter the entire machine will be, without affecting the structural rigidity of the first mounting plate 110 and the second mounting plate 120.

[0060] Please continue to refer to Figure 6In one embodiment of the present invention, the support assembly 130 includes a first support rod 1310 and a second support rod 1320, the first support rod 1310 and the second support rod 1320 are arranged side by side and spaced apart, and the positions of the first support rod 1310 and the second support rod 1320 and the rack 20 correspond. That is, the first support rod 1310 and the second support rod 1320 are used to improve the installation stability of the first mounting plate 110 for the rack 20. It can be understood that in addition to the first support rod 1310 and the second support rod 1320, the support assembly 130 can also be provided with more support rods to improve the structural rigidity of the first mounting plate 110 and the second mounting plate 120, for example, two or three support rods are arranged side by side with the first support rod 1310 and the second support rod 1320 to support the rack 20, so as to improve the supporting effect on the rack 20, so as to further improve the structural rigidity of the box shock absorbing structure 10.

[0061] Please continue to refer to Figure 5 and Figure 6 , a mounting hole 1110 communicating with the mounting space 140 is provided on the first mounting plate 110, and the rack 20 is covered with the mounting hole 1110, and the gas extracted by the fan assembly 30 can be introduced into the rack 20 through the mounting hole 1110. In one embodiment of the present invention, the spacing between the first support rod 1310 and the second support rod 1320 is consistent with the width of the rack 20. That is, the connection positions of the first support rod 1310 and the second support rod 1320 with the first mounting plate 110 correspond to the positions of the two opposite sides of the rack 20, so that the first support rod 1310 and the second support rod 1320 support the rack 20, thereby improving the supporting stability of the box shock-absorbing structure 10 for the rack 20, and then when the fan assembly 30 is in the running state, the rack 20 is in a stable state and will not shake due to the rotation of the fan assembly 30, thereby improving the vibration reduction effect of the box shock-absorbing structure 10.

[0062] Please refer to Figure 8 The marked areas B and C are the positions supported by the first support rod 1310. Please continue to refer to Fig. 9, the marked R area corresponds to the abutment position between the first support rod 1310 and the protruding plate 210, and corresponds to the bottom angle position on one side of the rack 20, so the first support rod 1310 has the best support effect on the rack 20, that is, one end of the first support rod 1310 abuts against the protruding plate 210 from the inner side of the installation space 140, and supports the protruding plate 210, thereby improving the support stability of the first support rod 1310 on the rack 20, and the second support rod 1320 is the same, which will not be described here. In one embodiment of the present invention, the rack 20 forms a projection area on the first mounting plate 110, and the position where the first support rod 1310 and the second support rod 1320 abut against the first mounting plate 110 falls within the projection area, so the first support rod 1310 and the second support rod 1320 can support the rack 20. The two corresponding sides of the rack 20 adjacent to the side close to the second mounting plate 120 are fastening sides 230, and the connection position of the first support rod 1310 and the first mounting plate 110 and the connection position of the second support rod 1320 and the second mounting plate 120 are arranged close to the fastening sides 230. It should be noted that the rack 20 is connected to the first mounting plate 110, and the first mounting plate 110 is connected to the second mounting plate 120, and the fan assembly 30 is connected to the first mounting plate 110 and the second mounting plate 120, and then during the operation of the fan assembly 30, the vibration effect generated will be directly transmitted to the first mounting plate 110 and the second mounting plate 120, and then the rack 20 connected to the first mounting plate 110 will be in a shaking state, and noise will be generated during the shaking of the rack 20, which seriously affects the user experience, and at the same time, the connection between the rack 20 and the first mounting plate 110 is connected by bolts, and the violent shaking will cause the bolts to loosen accordingly, thereby reducing the connection stability between the rack 20 and the first mounting plate 110. The first support rod 1310 and the second support rod 1320 abut against the side of the frame 20 away from the second mounting plate 120, and correspond to the opposite sides of the frame 20, so that the first support rod 1310 and the second support rod 1320 are arranged in a triangle with the first mounting plate 110 and the second mounting plate 120, thereby improving the support stiffness between the first mounting plate 110 and the second mounting plate 120, and then reducing the shaking intensity of the frame 20.

[0063] In one embodiment of the present invention, the first mounting plate 110 and the second mounting plate 120 can be integrally formed, or can be separately arranged and connected by welding or buckling. Further, the box shock-absorbing structure 10 also includes two side plates 150, and the side plates 150 are respectively connected to the first mounting plate 110 and the second mounting plate 120, and are respectively located on opposite sides of the first mounting plate 110 and the second mounting plate 120. In one embodiment of the present invention, the first support rod 1310 and the second support rod 1320 are arranged in parallel with the side plate 150. In this way, the side plate 150, the first support rod 1310 and the second support rod 1320 can simultaneously support the frame 20, that is, the side plate 150 can improve the stability between the first mounting plate 110 and the second mounting plate 120, and the first support rod 1310 and the second support rod 1320 can strengthen the stability between the first mounting plate 110 and the second mounting plate 120. Thus, when the fan assembly 30 in the installation space 140 is in operation, the first mounting plate 110 and the second mounting plate 120 can reduce the vibration caused by the fan assembly 30 under the support of the side plate 150 and the support assembly 130. It should be noted that at least one weight reduction hole 160 is also provided on the side plate 150.

[0064] Furthermore, at least one buffer 1210 is provided on the side of the second mounting plate 120 away from the mounting space 140. For example, two buffers 1210 may be provided, which are arranged near the position where the first support rod 1310 and the second support rod 1320 are connected to the second mounting plate 120. In one embodiment of the present invention, the buffer 1210 may be made of rubber material. The buffer 1210 is detachably connected to the second mounting plate 120. For example, a hole may be opened on the second mounting plate 120, and the buffer 1210 may be installed by screws. When the use time is too long, the screws are removed to facilitate the replacement of the buffer 1210. The provision of the buffer 1210 can reduce the vibration generated by the second mounting plate 120.

[0065] Please note that, please refer to Figure 6 and Fig.10 In one embodiment of the present invention, the first mounting plate 110 and the second mounting plate 120 are vertically arranged, so two buffers 1210 can be arranged near the second mounting plate 120 near the first mounting plate 110. The four buffers 1210 can reduce the vibration of the second mounting plate 120 and keep the second mounting plate 120 parallel to the wall. The two buffers 1210 arranged below the second mounting plate 120 are at a distance from the connection position between the first support rod 1310 and the second support rod 1320 and the second mounting plate 120, so as to achieve a better buffering effect. That is, Fig.10The position E shown is the force-bearing position between the second mounting plate 120 and the wall, and the position D is the resisting force-bearing position between the support assembly 130 and the first mounting plate 110. The support assembly 130 and the first mounting plate 110 and the second mounting plate 120 are arranged in a triangle, so that the support stability is higher. The positions of the two buffers 1210 above correspond to the projection points of the connection positions of the first support rod 1310 and the second support rod 1320 on the first mounting plate 110 on the second mounting plate 120. When the fan assembly 30 is in operation, the first mounting plate 110 and the second mounting plate 120 will be shaken by the swing of the fan. The buffer 1210 can buffer the vibration of the first mounting plate 110 and the second mounting plate 120 to avoid the first mounting plate 110 and the second mounting plate 120 from having a rigid impact on the wall and generating noise.

[0066] Please continue to refer to Figure 3 , Figure 4 as well as Figure 6 In one embodiment of the present invention, a volute support foot 310 is provided on one side of the fan assembly 30, and the fan assembly 30 is connected to the second mounting plate 120 through the volute support foot 310, and a volute flange 320 is also provided on the air outlet side of the fan assembly 30, and the fan assembly 30 is connected to the frame 20 through the volute flange 320. Therefore, whether the fan assembly 30 swings clockwise or counterclockwise, the swinging force will be transferred to the first mounting plate 110 and the second mounting plate 120. That is, the force is transmitted to the second mounting plate 120 through the volute support foot 310, and the force is transmitted to the first mounting plate 110 through the volute flange 320. The support assembly 130 can improve the installation stability of the first mounting plate 110 and the second mounting plate 120, thereby reducing the vibration intensity generated by the fan assembly 30. The provision of the buffer 1210 can further reduce the shaking intensity of the second mounting plate 120.

[0067] The bottom of the rack 20 is provided with a protruding plate 210, on which a plurality of first limiting holes 2110 are provided, and the first mounting plate 110 is provided with a plurality of second limiting holes 1120 corresponding to the first limiting holes 2110. The connection positions of the first support rod 1310 and the second support rod 1320 with the first mounting plate 110 correspond to the positions of the first limiting holes 2110. In one embodiment of the present invention, the protruding plate 210 passes through the mounting hole 1110 and is embedded in the mounting space 140, that is, when the rack 20 needs to be installed, the rack 20 can pass through the mounting hole 1110 from one side of the mounting space 140 until the protruding plate 210 abuts against the inner side of the first mounting plate 110 facing the mounting space 140. Then, the first mounting plate 110 and the rack 20 are tightly connected by rivets passing through the first limiting holes 2110 and the second limiting holes 1120 in sequence. Furthermore, when the first support rod 1310 and the second support rod 1320 are connected to the first mounting plate 110, the first support rod 1310 and the second support rod 1320 can be abutted against the protruding plate 210, and then fastened and connected by rivets. That is, the first support rod 1310 and the second support rod 1320 can directly connect the rack 20 and the first mounting plate 110. In this way, the first support rod 1310 and the second support rod 1320 can achieve the best supporting effect between the rack 20 and the first mounting plate 110.

[0068] It is understandable that in other embodiments, the rack 20 can also be placed above the first mounting plate 110, and then the protruding plate 210 and the first mounting plate 110 can be connected by rivets. It should be noted that a limiting groove can be set on the first mounting plate 110 along the projection area of ​​the bracket on the first mounting plate 110, so that the protruding plate 210 is embedded in the limiting groove, and the setting of the limiting groove prevents the protruding plate 210 from being exposed above the first mounting plate 110, thereby improving the user experience. At the same time, the setting of the limiting groove can limit the protruding plate 210, so that the rack 20 installation stability is higher. It should be noted that the connection position between the first support rod 1310 and the second support rod 1320 and the first mounting plate 110 can correspond to the position of the limiting groove, that is, the first support rod 1310 and the second support rod 1320 can form support for the first mounting plate 110 and the rack 20.

[0069] Please continue to refer to Figure 3 , Figure 6 and Figure 7 , a check valve 40 is also provided on the top of the frame 20. A guide channel 220 is provided on the frame 20, the air outlet of the fan assembly 30 corresponds to the air inlet of the guide channel 220, and the inlet of the check valve 40 corresponds to the air outlet of the guide channel 220. That is, the fan assembly 30 inputs the inhaled gas through the guide channel 220 to the check valve 40 for further transmission.

[0070] The range hood further includes a guide plate 50, which is connected to the first mounting plate 110 and the second mounting plate 120 and covers the mounting space 140. An oil cup 510 is also provided below the guide plate 50 for receiving liquid oil smoke that has seeped out after filtration. A smoke inlet is provided on the guide plate 50. When the fan assembly 30 is in operation, smoke from the outside is sucked in through the smoke inlet and then transmitted through the guide channel 220 and the check valve 40.

[0071] One side of the first mounting plate 110 away from the second mounting plate 120 is concave to form a mounting groove 1130, and one side of the guide plate 50 is provided with a matching plate 520 connected to the first mounting plate 110, and the matching plate 520 is embedded in the mounting groove 1130. It can be understood that the thickness of the matching plate 520 is consistent with the depth of the mounting groove 1130, so that after the matching plate 520 and the first mounting plate 110 are installed, the surface of the first mounting plate 110 is still flush.

[0072] To summarize, the first mounting plate 110 is used to install the frame 20, and the second mounting plate 120 and the first mounting plate 110 cooperate to install the fan assembly 30. When the fan assembly 30 is in operation, the vibration generated by the fan assembly 30 will be converted into the shaking of the first mounting plate 110 and the second mounting plate 120, and the setting of the support assembly 130 can improve the structural stiffness of the first mounting plate 110 and the second mounting plate 120, thereby reducing the shaking of the first mounting plate 110 and the second mounting plate 120 caused by the operation of the fan assembly 30.
