Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, and in particular to a fastening and shock-absorbing component, a motor component and a range hood. Background Art

[0002] Currently, a common practice for securing one structural component to another is to connect it to the other component using fasteners such as screws. However, for components operating in vibrating environments, such as the motor assembly in a range hood, the motor needs to be connected to the bracket using screws. However, existing screw connections fail to meet vibration reduction requirements. During operation, the motor assembly may generate axial and radial vibrations, which are then transmitted to the bracket, causing unnecessary noise. This not only affects the user's cooking experience but can also endanger their physical and mental health. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a fastening and shock absorbing assembly is provided, and the technical solution is as follows.

[0004] The fastening and shock-absorbing assembly includes a fastening body, a shock-absorbing splint and an elastic member. The fastening body has a head and a connecting shaft, and the head is connected to one end of the connecting shaft; the shock-absorbing splint has a plate body, an extension body and a shock-absorbing pad, the extension body is bent and extended from the edge of the plate body relative to the plate body, the shock-absorbing pad is connected to the extension body, and the connecting shaft is passed through the plate body; the elastic member is arranged between the head and the plate body.

[0005] The fastening and shock-absorbing assembly of the present invention can not only fasten one structural member to another structural member, but also, when the connected structural member vibrates, the elastic potential energy of the elastic member can offset the axial vibration, and the shock-absorbing pad can offset the radial vibration, thereby achieving a shock-absorbing effect and reducing noise.

[0006] For example, an angle α1 is formed between the extension and the plate body, and the angle α1 is between 135° and 150°. When the angle α1 is within this range, the shock-absorbing pad can effectively offset radial vibration when it is used in conjunction with another structural member, and can also disperse some axial vibration radially to offset it, thereby achieving a good shock absorption effect.

[0007] For example, the plate body has a first section and a second section along its length, with the extension formed at the edge of the first section and a connecting groove formed in the second section. This arrangement allows connection to a structural member via the connecting groove, resulting in a more stable connection. Furthermore, when the structural member vibrates, it is more likely to drive the plate body to compress the elastic member, thereby generating elastic potential energy in the elastic member to offset axial vibration.

[0008] For example, a through hole is formed in the plate body, and the connecting shaft portion is configured as a threaded segment at the end away from the head, with the threaded segment at least partially extending out of the through hole. This arrangement ensures that the fastening and damping assembly can fasten one structural member to another structural member through the cooperation of the threaded segment.

[0009] For example, the extension body has a latching hole with a lateral opening, and the shock-absorbing pad has a latching portion that snaps into the latching hole through the lateral opening. This arrangement ensures a stable connection between the shock-absorbing pad and the extension body and facilitates installation and removal of the shock-absorbing pad from the extension body, facilitating cleaning or replacement of the shock-absorbing pad.

[0010] For example, the size L1 of the lateral opening is smaller than the diameter L2 of the latch through hole. This arrangement reduces the possibility of the shock-absorbing pad falling out relative to the latch through hole, thereby ensuring the shock-absorbing effect.

[0011] For example, the shock-absorbing pad includes a first connecting portion and a second connecting portion, each located at either end of the latch portion. The first, latch portion, and second connecting portions together form a latch slot, and the first and second connecting portions abut against opposite surfaces of the extension body. This arrangement enhances the stability of the connection between the shock-absorbing pad and the extension body and effectively offsets vibrations transmitted from the extension body to the shock-absorbing pad.

[0012] According to another aspect of the present invention, a motor assembly is provided, comprising a motor, a bracket, and the aforementioned fastening and damping assembly, wherein the motor is connected to the bracket via the fastening and damping assembly. In this manner, axial vibration of the motor drives the plate body to compress the elastic member, causing the elastic member to generate elastic potential energy to offset the axial vibration. The damping pad cooperates with the bracket to offset radial vibration. Even if some axial vibration is dispersed radially, it can be offset by the damping pad, thereby achieving a vibration-damping effect and reducing noise.

[0013] For example, the motor has a connecting flange, and the plate body has a first section and a second section along its length. The extension is formed at the edge of the first section, and a connecting groove is formed in the second section. The connecting flange connects to the connecting groove. This arrangement provides a more stable connection through the connecting groove and the connecting flange. When the motor vibrates, the connecting flange more easily drives the plate body to compress the elastic member, thereby generating elastic potential energy in the elastic member to offset axial vibration.

[0014] Exemplarily, the bracket includes an annular body, at least two legs, and at least two first arc-shaped flanges. The annular body has a first surface and a second surface that are arranged opposite each other. The legs are at least partially located on the side where the first surface is located, and the first arc-shaped flange is at least partially located on the side where the second surface is located. The at least two first arc-shaped flanges and the annular body are enclosed to form a receiving portion. The plate body is located in the receiving portion, and the shock-absorbing pad abuts against the first arc-shaped flange. With this arrangement, when the motor vibrates axially, the up and down movement of the motor can drive the plate body to squeeze the elastic member, causing the elastic member to generate elastic potential energy to offset the vibration, thereby achieving the effect of axial vibration reduction and noise reduction of the motor. By placing the plate body in the receiving portion, the shock-absorbing pad is facilitated to abut against the first arc-shaped flange. The radial vibration of the motor can be achieved through the interaction between the shock-absorbing pad and the first arc-shaped flange, thereby achieving vibration reduction and noise reduction.

[0015] For example, an angle α2 is defined between the first curved flange and the annular body, and this angle α2 is between 135° and 150°. Within this range, the shock-absorbing pad connected to the extension body more easily abuts the first curved flange, effectively offsetting radial vibration generated by the motor. Even if some axial vibration generated by the motor is dispersed radially, the shock-absorbing pad can still offset it, further ensuring the vibration reduction effect.

[0016] For example, the central angle β1 of the first curved flange is between 30° and 60°. Within this range, the first curved flange interacts with the shock-absorbing pad to effectively reduce radial vibration generated by the motor. Even if some axial vibration is dispersed radially, it can be further reduced by the shock-absorbing pad, thereby achieving a good vibration reduction effect and ensuring the stability of the connection between the first curved flange and the annular body.

[0017] For example, the first curved flange has a flange length L3, which is 10 mm to 20 mm. When the flange length L3 is within this range, the shock-absorbing pad can abut against the first curved flange, thereby achieving a good shock-absorbing effect and ensuring the strength of the first curved flange.

[0018] For example, at least two legs and at least two first curved flanges are spaced apart along the circumference of the annular body, with a first curved flange positioned between each pair of adjacent legs. This arrangement prevents the first curved flange from being too close to the legs, potentially obstructing the installation of other components, and also prevents the first curved flange from being integrally formed with the legs. This prevents vibrations generated by the motor during operation from being transmitted through the legs to other components, potentially generating significant noise, when connected to the motor.

[0019] For example, a cushion is positioned between the annular body and the plate body, and the connecting shaft sequentially passes through and connects the plate body, the cushion, and the annular body. This arrangement allows the plate body to compress the elastic member, generating elastic potential energy that offsets motor vibration. The cushion then reduces vibration between the annular body and the plate body, further enhancing the motor's axial vibration and noise reduction effects.

[0020] According to another aspect of the present invention, a range hood is provided, comprising a volute and the motor assembly described above, the motor assembly being disposed on the volute. Since the motor assembly described above has the aforementioned beneficial effects, a range hood including the motor assembly also has the aforementioned beneficial effects, which will not be further elaborated herein.

[0021] The Summary of the Utility Model introduces a series of simplified concepts, which will be further described in detail in the Detailed Description of the Utility Model. This Summary of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0038] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0039] To thoroughly understand the embodiments of the present invention, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0040] An embodiment of the present invention provides a fastening and damping assembly. According to another aspect of the present invention, a motor assembly is provided, in which the fastening and damping assembly can be employed. Furthermore, the motor assembly provided by the present invention can be employed in a range hood. The fastening and damping assembly, motor assembly, and range hood provided by the present invention are described in detail below with reference to the accompanying drawings.

[0041] See Figure 1 The fastening and shock absorbing assembly 100 may include a fastening body 110, a shock absorbing splint 120 and an elastic member 130. The fastening body 110 may have a head 111 and a connecting shaft portion 112. The head 111 may be connected to one end of the connecting shaft portion 112. The shock absorbing splint 120 may have a plate body 121, an extension body 122 and a shock absorbing pad 123. The extension body 122 may be bent and extended from the edge of the plate body 121 relative to the plate body 121. The shock absorbing pad 123 may be connected to the extension body 122. The connecting shaft portion 112 may be passed through the plate body 121. The elastic member 130 may be arranged between the head 111 and the plate body 121. It can be understood that the elastic member 130 is sleeved outside the connecting shaft portion 112.

[0042] The fastening and shock-absorbing assembly 100 of the present invention can not only fasten one structural member to another structural member, but also when the connected structural member vibrates, the elastic potential energy of the elastic member 130 can offset the axial vibration, and the shock-absorbing pad 123 can offset the radial vibration, thereby achieving a shock-absorbing effect and reducing noise.

[0043] Specifically, the material of the shock-absorbing pad 123 can be rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the shock-absorbing pad 123 can also be made of other materials. The elastic member 130 can be connected to the head 111 and the plate body 121 respectively. When the plate body 121 moves due to vibration, the vibration can be better converted into elastic potential energy of the elastic member 130. The connection method of the elastic member 130 to the plate body 121 and the head 111 can be welding, gluing, etc. The elastic member 130 can be a spring, etc.

[0044] Further, see Figures 1 to 3, the head 111 can be provided with a gripping part 1111, and the shock absorption component 100 can be installed and fastened without the aid of other tools. The gripping part 1111 can extend from the end face of the head 111 away from the connecting shaft part 112, which is easy to produce or manufacture and saves costs. Of course, it is not excluded that the gripping part 1111 extends from the side wall of the head 111, or the gripping part 1111 and the head 111 are of a split structure, and the two are connected by connection methods such as snap connection and pasting, etc.

[0045] Referring to Figures 1 to 4 , an angle α1 can be provided between the extension body 122 and the plate body 121. The angle α1 can be 135° to 150°, for example, α1 can be 135°, 145°, 150°, etc. When the angle α1 is within this range, when the shock pad 123 cooperates with another structural member, the effect of canceling out the radial vibration is better, and part of the axial vibration can be dispersed to the radial direction to cancel it out, so as to achieve a better shock absorption effect.

[0046] Referring to again Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , the plate body 121 can have a first section 1211 and a second section 1212 in the length direction. Understandably, the length direction is along the axis direction of the connecting shaft part 112. The extension body 122 can be formed at the edge of the first section 1211. A connecting groove 1213 can be formed on the second section 1212. That is to say, the second section 1212 can be recessed toward the connecting shaft part 112, the first section 1211 and the second section 1212 can be connected, and the first section 1211 and the second section 1212 can enclose to form the connecting groove 1213. Thus, by connecting with a structural member through the connecting groove 1213, the connection stability is higher, and when the structural member vibrates, it is easier to drive the plate body 121 to move to squeeze the elastic member 130, so that the elastic member 130 generates elastic potential energy to cancel the axial vibration. Specifically, as Figure 3 and Figure 4 , the plate body 121 can be in an "I" shape. As Figure 6 , the plate body 121 can also be in a "C" shape, etc. Of course, it is not excluded that the extension body 122 can be formed at the edge of the second section 1212, and the connecting groove 1213 can be formed on the first section 1211.

[0047] Referring to Figure 1 , Figure 2 and Figure 4, a through hole 1214 may be formed in the plate body 121. The connecting shaft portion 112 may be configured as a threaded section 1121 at the end away from the head portion 111. The threaded section 1121 may at least partially extend out of the through hole 1214. In this way, the threaded section 1121 cooperates to ensure that the fastening shock absorbing assembly 100 can fasten one structural member to another structural member. Specifically, after the connecting shaft portion 112 passes through the through hole 1214, the connecting shaft portion 112 and the plate body 121 may be connected by welding or interference fit.

[0048] See also Figure 1 and Figure 2 The extension body 122 may have a latching hole 1221 with a lateral opening 1222. The shock-absorbing pad 123 may have a latching portion 1231. The latching portion 1231 can be latched into the latching hole 1221 through the lateral opening 1222. This ensures the stability of the connection between the shock-absorbing pad 123 and the extension body 122 and facilitates installation or removal of the shock-absorbing pad 123 relative to the extension body 122, facilitating cleaning or replacement of the shock-absorbing pad 123.

[0049] Again, refer to Figure 1 、 Figure 2 and Figure 4 The size L1 of the lateral opening 1222 can be smaller than the aperture L2 of the latching hole 1221. Preferably, the latching hole 1221 can be circular for ease of processing and manufacturing. Of course, shapes such as square or oval are not excluded. The lateral opening 1222 can have a first wall 1222a and a second wall 1222b. The first wall 1222a and the second wall 1222b can be disposed opposite each other, and the distance between the first wall 1222a and the second wall 1222b can be equal to the size L1 of the lateral opening 1222. This reduces the possibility of the shock-absorbing pad 123 being dislodged from the latching hole 1221, thereby ensuring a shock-absorbing effect. Specifically, because the shock-absorbing pad 123 has a certain elastic force and elastic recovery ability, the latching portion 1231 can be pushed and compressed through the lateral opening 1222 to enter the latching hole 1221, and then recover through its elastic recovery ability to engage with the latching hole 1221.

[0050] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6The shock-absorbing pad 123 may include a first connecting portion 1232 and a second connecting portion 1233. The first connecting portion 1232 and the second connecting portion 1233 may be located at either end of the latch portion 1231. The first connecting portion 1232, the latch portion 1231, and the second connecting portion 1233 may together form a latch groove 1234, and the first connecting portion 1232 and the second connecting portion 1233 may respectively abut against two opposing surfaces of the extension body 122. This enhances the stability of the connection between the shock-absorbing pad 123 and the extension body 122, and effectively offsets vibrations transmitted from the extension body 122 to the shock-absorbing pad 123. Specifically, the shock-absorbing pad 123 may be a block-shaped structure or a plate-shaped structure. The first connecting portion 1232 may be a latching joint. The latch portion 1231 may be a cylindrical segment that latches into the latching through hole 1221 with a lateral opening 1222 of the extension body 122. The second connection portion 1233 may be a shock-absorbing block, which may interact with another structural component to achieve a radial shock-absorbing effect.

[0051] In an embodiment not shown in the figures, the shock-absorbing pad 123 and the extension body 122 can be connected by bonding or screw connection.

[0052] See also Figure 1 and Figure 7 According to another aspect of the present invention, a motor assembly 10 is provided. The motor assembly 10 may include a motor 200, a bracket 300 and the fastening shock-absorbing assembly 100 as described above. The motor 200 may be connected to the bracket 300 through the fastening shock-absorbing assembly 100. Specifically, the plate body 121 is connected to the motor 200, the connecting shaft 112 is connected to the bracket 300, and then cooperates with the bracket 300 through the shock-absorbing pad 123. In this way, the axial vibration of the motor 200 can drive the plate body 121 to squeeze the elastic member 130, so that the elastic member 130 generates elastic potential energy to offset the axial vibration. Through the cooperation of the shock-absorbing pad 123 and the bracket 300, the radial vibration can be offset by the shock-absorbing pad 123. Even if part of the axial vibration is dispersed to the radial direction, it can also be offset by the shock-absorbing pad 123. In this way, the shock absorption effect is achieved and the noise is reduced.

[0053] See also Figure 1 、 Figure 2 and Figure 7, the motor 200 may have a connecting flange portion 210. The plate body 121 may have a first section 1211 and a second section 1212 in the length direction. The extension body 122 may be formed at the edge of the first section 1211. A connecting groove 1213 may be formed on the second section 1212. The connecting flange portion 210 and the connecting groove 1213 may be connected. In this way, by connecting the connecting groove 1213 and the connecting flange portion 210, the stability of the connection is higher, and when the motor 200 vibrates, it is easier to drive the plate body 121 to move through the connecting flange portion 210 to squeeze the elastic member 130, so that the elastic member 130 generates elastic potential energy to offset the axial vibration. Specifically, as Figure 8 The connecting flange portion 210 may have a mounting hole 211 with a notch formed on the side, and the connecting groove 1213 may be matched with the mounting hole 211 through the notch. Figure 9 , a mounting hole 211 may be provided near the edge of the connecting flange portion 210, the connecting flange portion 210 is at least partially placed in the connecting groove 1213, and the center of the mounting hole 211 is on the same straight line as the center of the through hole 1214, the connecting shaft portion 112 passes through the through hole 1214 and the mounting hole 211 in sequence, and the threaded section 1121 at least partially passes through the mounting hole 211, thereby connecting the connecting flange portion 210 to the plate body 121. The number of connecting flange portions 210 may be one or more. Preferably, in order to improve the stability of the connection of the motor 200, the flange portion may be a plurality of flange structures. Of course, it is not excluded that when the number of connecting flange portions 210 is one, an annular flange structure may be formed circumferentially around the motor 200. It should be noted that the number of fastening shock absorbing assemblies 100 may be consistent with the number of connecting flange portions 210.

[0054] Furthermore, an elastic pad (not shown) may be sandwiched between the connecting flange portion 210 and the first section 1211, thereby reducing the vibration generated between the motor 200 and the fastening and shock-absorbing assembly 100 and reducing noise. An elastic pad may be sandwiched between the connecting flange portion 210 and the second section 1212, further reducing the vibration generated between the motor 200 and the fastening and shock-absorbing assembly 100 and further reducing noise. The elastic pad may be made of rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the elastic pad may also be made of other materials.

[0055] See also Figure 7 、 Figure 10 and Figure 11The bracket 300 may include an annular body 310, at least two legs 320, and at least two first curved flanges 330. The annular body 310 may have a first surface 311 and a second surface 312 disposed opposite to each other. The legs 320 may be at least partially located on the side where the first surface 311 is located. The first curved flange 330 may be at least partially located on the side where the second surface 312 is located, and the at least two first curved flanges 330 and the annular body 310 may enclose a receiving portion 340. The plate body 121 may be located in the receiving portion 340. The shock-absorbing pad 123 may abut against the first curved flange 330. In this way, when the motor 200 vibrates axially, the up and down jumping of the motor 200 can drive the plate body 121 to squeeze the elastic member 130, so that the elastic member 130 generates elastic potential energy to offset the vibration, thereby achieving the axial shock absorption and noise reduction effect of the motor 200; by placing the plate body 121 in the accommodating portion 340, it is convenient for the shock absorbing pad 123 to abut against the first arc-shaped flange portion 330, and the radial vibration of the motor 200 can interact with the shock absorbing pad 123 and the first arc-shaped flange portion 330 to achieve shock absorption and noise reduction.

[0056] In some embodiments, in conjunction with Figure 1 and Figure 10 The annular body 310 is provided with threaded holes 313 at intervals along the circumference, and the threaded sections 1121 are threadedly connected to the threaded holes 313. This ensures the stability of the connection between the motor 200 and the bracket 300 and facilitates installation or removal for cleaning or maintenance.

[0057] In some embodiments, again in conjunction with reference to Figure 7 、 Figure 10 and Figure 11The support leg 320 may have a first end 321 and a second end 322. The first end 321 may be connected to the first surface 311, and the first end 321 to the second end 322 may all be located on the side where the first surface 311 is located. The first arc-shaped flange portion 330 may form an arc segment around the annular body 310, and the first arc-shaped flange portion 330 may extend from the outer edge of the annular body 310 toward the side where the second surface 312 is located. In this way, it is convenient to connect the bracket 300 with other components, and it is convenient to cooperate between the first arc-shaped flange portion 330, the motor 200 and the fastening shock-absorbing assembly 100. Of course, the first end 321 may also be connected to the second surface 312, and the second end 322 may be located on the side where the first surface 311 is located; or the support leg 320 may extend from the outer edge of the annular body 310 toward the side where the first surface 311 is located, etc. It is also possible that the first curved flange portion 330 can be a plate-like member; one end of the plate-like member can be connected to the second surface 312, and the end to the other end can be located on the side where the second surface 312 is located; or one end of the plate-like member can be connected to the first surface 311, and the other end can be located on the side where the second surface 312 is located. In summary, the support leg 320 and the annular body 310, as well as the first curved flange portion 330 and the annular body 310, can be an integrated structure or a split structure. When the support leg 320 and the annular body 310, as well as the first curved flange portion 330 and the annular body 310, are split structures, their connection method can be adhesive bonding, screw connection, etc., which is not specifically limited here.

[0058] Preferably, the number of the first curved flange portions 330 can be the same as the number of the connecting flange portions 210. The number of the first curved flange portions 330 can be four, which can effectively improve the shock absorption effect. Of course, the number of the first curved flange portions 330 can also be three, five, or six, etc.

[0059] In an embodiment not shown in the figures, at least a portion from one end of the first arc-shaped flange portion 330 connected to the annular body 310 to the other end may also be an arc segment to enhance the shock-absorbing effect on axial vibration.

[0060] See also Figure 1 、 Figure 7 、 Figure 10 and Figure 11, an angle α2 may be present between the first arc-shaped flange portion 330 and the annular body 310. The angle α2 may be between 135° and 150°, for example, α2 may be 135°, 145°, 150°, etc. When the angle α2 is within this range, the shock-absorbing pad 123 connected to the extension body 122 is more likely to abut against the first arc-shaped flange portion 330, thereby better offsetting the radial vibration generated by the motor 200. Even if part of the axial vibration generated by the motor 200 is dispersed radially, the shock-absorbing pad 123 can also better offset it, thereby further ensuring the shock-absorbing effect. The extension body 122 and the first flange portion may be arranged in parallel to facilitate the abutment of the shock-absorbing pad 123.

[0061] Again, refer to Figure 1 、 Figure 7 、 Figure 10 and Figure 11 The central angle β1 of the first arcuate flange portion 330 can be between 30° and 60°, for example, 30°, 45°, 60°, etc. Within this range of central angle β1, the first arcuate flange portion 330 interacts with the shock-absorbing pad 123 to effectively reduce radial vibration generated by the motor 200. Even if some axial vibration is dispersed radially, it can be further reduced by the shock-absorbing pad 123, thereby achieving a good vibration reduction effect and ensuring the stability of the connection between the first arcuate flange portion 330 and the annular body 310.

[0062] Again, refer to Figure 1 、 Figure 7 、 Figure 10 and Figure 11 The first curved flange portion 330 can have a flange length L3. The flange length L3 can be 10 mm to 20 mm, for example, 10 mm, 15 mm, 20 mm, etc. Within this range, the flange length L3 can ensure that the shock-absorbing pad 123 abuts against the first curved flange portion 330, thereby achieving a good shock-absorbing effect and ensuring the strength of the first curved flange portion 330.

[0063] Again, refer to Figure 7 、 Figure 10 and Figure 11At least two legs 320 and at least two first curved flanges 330 can be spaced apart along the circumference of the annular body 310, and a first curved flange 330 can be provided between every two adjacent legs 320 along the circumference of the annular body 310. This prevents the first curved flange 330 from being too close to the legs 320, thereby obstructing the installation of other components, and also prevents the first curved flange 330 from being an integrated structure with the legs 320. Thus, when connected to the motor 200, vibrations generated during operation of the motor 200 can be prevented from being transmitted to other components through the legs 320, thereby generating loud noise.

[0064] Again, refer to Figure 1 and Figure 7 , a buffer pad 400 can be provided between the annular body 310 and the plate body 121. The connecting shaft portion 112 can sequentially pass through and connect the plate body 121, the buffer pad 400 and the annular body 310. In this way, the elastic member 130 is squeezed by the plate body 121, so that the elastic member 130 generates elastic potential energy to offset the vibration of the motor 200, and then the vibration between the annular body 310 and the plate body 121 is reduced by the buffer pad 400, thereby further enhancing the axial shock absorption and noise reduction effect of the motor 200. Specifically, the material of the buffer pad 400 can be rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the buffer pad 400 can also be made of other materials. The shape of the buffer pad 400 can be similar to that of the annular body 310, forming a ring to comprehensively reduce the shock of the annular body 310.

[0065] See Figure 12 According to another aspect of the present invention, a range hood is provided. The range hood may include a volute 11 and the motor assembly 10 as described above. The motor assembly 10 may be arranged on the volute 11. Since the motor assembly 10 as described above has the above-mentioned beneficial effects, the range hood including the motor assembly 10 as described above also has the above-mentioned beneficial effects, which will not be described in detail here. Specifically, the motor assembly 10 is connected to the volute 11 through the support leg 320. It can be understood that the end of the support leg 320 away from the bracket 300 is connected to the volute 11. The volute 11 and the support leg 320 can be connected by screw connection, welding, etc., which are not specifically limited here.
