The following is described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the motor mounting bracket 11 may be used to mount the motor 12 (shown in fig. 4) and provide a bearing for the motor 12, so that the motor 12 may be more stably mounted in an external structure (e.g., inside the drying apparatus 100).

The housing 111 may be formed with a receiving cavity 1111, and the receiving cavity 1111 may be used to receive the motor 12. The motor 12 may be connected to the housing 111 by clamping, gluing, welding, or screwing, and the airflow generated by the motor 12 may flow out of the housing 111 and towards components (e.g., the bracket 114) located downstream of the housing 111. The housing 111 includes an inner wall 1112 and an outer wall 1113, the inner wall 1112 being positioned within the housing 1111 and opposite or in contact with the motor 12. The housing 111 may be made of a hard material, such as a hard plastic or metal.

Referring to fig. 1, in some embodiments, the housing 111 may be provided with a through hole 1118 communicating with the receiving cavity 1111 and penetrating the outer wall 1113 and the inner wall 1112, and the through hole 1118 may reduce the weight of the housing 111, and thus the weight of the motor mounting bracket 11. In addition, glue can be dispensed into the housing 111 through the through hole 1118, so that the motor mounting bracket 11 and the motor 12 can be connected together more stably. Further, the through hole 1118 may allow wires to pass through to connect with the motor 12, i.e., to facilitate routing. In addition, the through hole 1118 can also reserve installation positions for other components, so that the installation space is saved, and the structure of the device provided with the motor installation frame 11 is more compact.

Referring to fig. 1, the damping element 112 is located outside the housing 111, and may be connected to the outer wall 1113 of the housing 111, for example, the damping element 112 may abut against the outer wall 1113 of the housing 111, the damping element 112 may be welded, clamped, and adhered to the outer wall 1113 of the housing 111, and the damping element 112 may be elastically deformed when a force (e.g., a pressure or a tensile force) is applied. In some embodiments, the damping members 112 may abut against the outer wall 1113 of the housing 111 without being fixed to each other, the damping members 112 are positioned on the outer wall of the housing 111 by providing other related positioning structures to buffer the pressure, and the plurality of damping members 112 surround the outer periphery of the housing 111 and buffer the pressure applied thereto in each direction; in this embodiment, the end of the damping member 112 is fixed to the outside of the housing 111, that is, in addition to damping the pressure, the end of the damping member 112 is connected to the housing 111 and can bear a certain tensile force, and the damping member 112 can also damp the tensile force. In addition, since the motor 12 receives a torque opposite to the rotation direction when the motor 12 rotates to output the torque, that is, after the motor 12 is accommodated and fixed in the housing 111, in operation, there is a pressure and tension vibration to the housing 111, and there is an axial rotation tendency, at this time, the ends of the plurality of vibration dampers 112 are connected to the outer wall of the housing 111, so that the housing 111 can be fixed to buffer the torque received by the housing 111, and the vibration generated when the housing 111 rotates in the circumferential direction is avoided. Specifically, the damping member 112 may be made of an elastic material such that the damping member 112 may be elastically deformed. The elastic material may be silicone or rubber, which is not listed here. When the force is applied, the vibration damping member 112 may undergo at least one of expansion, bending, shearing deformation and composite deformation, so that the vibration damping member 112 may buffer axial vibration and radial vibration generated by the motor 12, and the motor mount 11 may have better vibration damping performance. Further, the damping member 112 may also be made in a spring shape so that the damping member 112 may be compressed and extended, and the damping member 112 may also swing, thereby further improving the damping performance of the damping member 112.

The number of the vibration dampers 112 may be plural, for example, the vibration dampers 112 may be 2, 3, 4, 5, 6, 7, 8, or 9 or even more, and the plural vibration dampers 112 may be connected to the outer wall 1113 of the housing 111. The plurality of vibration dampers 112 may be randomly distributed on the outer wall 1113 of the housing 111, or the plurality of vibration dampers 112 may be uniformly distributed on the outer wall 1113 of the housing 111, or the plurality of vibration dampers 112 may be arranged in a plurality of groups on the outer wall 1113 of the housing 111, and the plurality of groups of vibration dampers 112 may be sequentially disposed at different positions on the housing 111 along the axial direction O1 of the housing 111.

Referring to fig. 2 and 3, the damping element 112 may include a first connection portion 1121 and a second connection portion 1122 opposite to each other, the first connection portion 1121 may be connected to an outer wall 1113 of the housing 111, and the second connection portion 1122 may be connected to the clip 113. In some embodiments, the first connection portion 1121 may be detachably connected to the outer wall 1113 of the housing 111, for example, the first connection portion 1121 may be detachably connected to the outer wall 1113 of the housing 111 by snapping, screwing, or screwing. In other embodiments, the first connection portion 1121 may be fixedly connected to the outer wall 1113 of the housing 111, for example, the first connection portion 1121 may be fixedly connected to the outer wall 1113 of the housing 111 by welding, bonding, gluing, or injection molding.

In some embodiments, the material of the vibration damper 112 may be different from the material of the housing 111. Specifically, the vibration dampers 112 may be made of an elastic material, and the housing 111 may be made of a hard material, so that the housing 111 may have high hardness and facilitate installation of the motor 12, while the vibration dampers 112 may have good vibration damping performance. For example, the vibration damper 112 is made of silicone rubber or rubber, and the housing 111 is made of plastic or metal. In some embodiments, the damping member 112 is made of a different material than the housing 111 and the snap member 113, for example, the damping member 112 is made of an elastic material and the housing 111 and the snap member 113 are made of a hard material.

Referring to fig. 1, in some embodiments, a plurality of mounting platforms 11131 are disposed on an outer wall 1113 of the housing 111, the first connecting portions 1121 of the plurality of vibration dampers 112 may be connected to the plurality of mounting platforms 11131 in a one-to-one correspondence, and after the first connecting portions 1121 are connected to the mounting platforms 11131, the mounting platforms 11131 may limit the movement of the first connecting portions 1121 on the outer wall 1113, for example, the mounting platforms 11131 may limit the movement of the first connecting portions 1121 along the axial direction O1, or limit the movement of the first connecting portions 1121 around the circumferential direction of the outer wall 1113; or the mounting platform 11131 may wrap the first connection portion 1121 such that the first connection portion 1121 is not easily moved on the outer wall 1113 of the housing 111. In addition, if the first connection portion 1121 is welded or bonded to the outer wall 1113, the mounting base 11131 may be used to accommodate an overflow of solder or an overflow of solder.

Referring to fig. 2, in some embodiments, the vibration damping member 112 may further include a telescopic portion 1123 located between the first connecting portion 1121 and the second connecting portion 1122, and at least a portion of the telescopic portion 1123 is capable of being extended and contracted when a force is applied. When the damping member 112 is under tension, part or the whole of the folds 1123 can stretch; when the damping member 112 is subjected to pressure, part or the whole of the bellows 1123 may be compressed. The vibration damping member 112 can thus have a good damping effect on the vibration generated by the motor 12. Further, in one embodiment, the bellows 1123 may include a plurality of pleats 11231, the number of pleats 11231 may be multiple layers, and a portion of the plurality of pleats 11231 or all of the plurality of pleats 11231 may flex when subjected to a force. In the embodiment shown in fig. 2, the portion of the vibration damper 112 between the first connection portion 1121 and the second connection portion 1122 may be both the expansion portion 1123, and the entire expansion portion 1123 may be the corrugations 11231.

Referring to fig. 3, in another embodiment, the expansion portion 1123 may include a first corrugation 1124 connected to the first connection portion 1121 and a second corrugation 1125 connected to the second connection portion 1122, and the vibration damping member 112 may further include an extension portion 1120 located between the first corrugation 1124 and the second corrugation 1125. The first pleat 1124 is connected to a first connection portion 1121, the second pleat 1125 is connected to a second connection portion 1122, the extension portion 1120 is connected to the first pleat 1124 and the second pleat 1125, and the extension portion 1120 is a cylinder without forming a pleat. The first and

second pleats

1124, 1125 may each be pleated (the cross-section of the pleats may be curved, triangular, irregular, etc.), the length of the first and

second pleats

1124, 1125 may be the same or different, and the number of pleats included in the first and

second pleats

1124, 1125 may be the same or different.

Further, first pleat 1124 is able to flex when subjected to a force, e.g., first pleat 1124 may be stretched when subjected to a tensile force and first pleat 1124 may be compressed when subjected to a compressive force. Second pleats 1125 are capable of telescoping when stressed, e.g., second pleats 1125 may be stretched when under tension and second pleats 1125 may be compressed when under compression. Therefore, compared with a vibration damping member without wrinkles, the vibration damping member 112 of the present embodiment may have a better vibration damping performance, so that the motor mounting bracket 11 may play a better vibration damping role when the motor 12 vibrates. The first corrugations 1124 and the second corrugations 1125 may each expand and contract and may bend when the motor 12 vibrates, for example, when the motor 12 vibrates, a cross section of the vibration damping member 112 perpendicular to the axial direction of the housing 12 may have an S shape, a C shape, a half S shape, and the like, so as to sufficiently damp axial and radial vibrations generated by the motor 12.

In addition, since the extension portion 1120 is not provided with wrinkles, and the first wrinkles 1124 and the second wrinkles 1125 are provided with wrinkles, the elastic deformability of the extensions 1120 is less than the elastic deformability of the first corrugations 1124 and less than the elastic deformability of the second corrugations 1125, so that the three parts of the damping member 112 have different damping capabilities, and a portion having a strong vibration damping capability is disposed at a position closest to the vibration source and the conductive member, for example, the first corrugation 1124 is disposed at a position closest to the vibration source, i.e., the closest location of the motor 12, and a second pleat 1125 is disposed in contact with the conductive member, i.e., the closest position of the outer structure, the influence of the vibrations of the motor 12 on the outer structure is damped to the greatest extent, and a portion having a weak damping capacity is disposed at a middle position, for example, the extension portion 1120 is disposed at a middle position, the vibration damping member 112 can be ensured not to be in transition deflection deformation, and the working stability of the motor 12 can be ensured.

Of course, in other embodiments, the damping capacity of the first corrugations 1124, the damping capacity of the extension portion 1120, and the damping capacity of the second corrugations 1125 may be sequentially weakened, and since the conduction of the vibration is generally weakened, the gradually weakened damping portions may be sequentially arranged along the conduction direction, so as to not only ensure the damping effect, but also avoid the transient deflection deformation of the damping member 112, and ensure the stability of the operation of the motor 12. Alternatively, in other embodiments, it is also contemplated that first corrugations 1124 may be used to dampen radial vibrations generated by the motor and second corrugations 1125 may be used to dampen axial vibrations of the outer structure.

Further, the first pleat 1124, the extension portion 1120, and the second pleat 1125 may be made of different materials to have different cushioning abilities, and the first pleat 1124, the extension portion 1120, and the second pleat 1125 may be fused to form the damping member 112 by multi-molding, dual-color molding, or multi-color molding. Alternatively, the first pleats 1124 and the second pleats 1125 may be made of the same material, the extension portion 1120 may be made of a material different from the material of the first pleats 1124 and the material of the second pleats 1125, the first pleats 1124 and the second pleats 1125 may have the same shape, and the first pleats 1124, the extension portion 1120 and the second pleats 1125 may be fused to form the damper 112 by multiple molding, two-color molding or multi-color molding. Alternatively, the first pleats 1124 may be made of two or more material segments and the second pleats 1125 may be made of two or more material segments, such that the damping capacity of different segments of the first pleats 1124 and the second pleats 1125 may differ, e.g., the damping capacity of the first pleats 1124 may gradually decrease and the damping capacity of the second pleats 1125 may gradually increase in a direction away from the housing 111. Still alternatively, the first and

second pleats

1124, 1125 may be made of the same material, and the first and

second pleats

1124, 1125 may differ in shape, for example: the length of the pleats in the first pleats 1124 may be less than or greater than the length of the pleats in the second pleats 1125, the cross-section perpendicular to the axial direction of the housing 111, the cross-section of the pleats in the first pleats 1124 may be arcuate, the outer surface of the pleats in the second pleats 1125 may be tapered, or vice versa.

Of course, the first fold 1124, the extension portion 1120, and the second fold 1125 are not limited to the structures described in the above embodiments, and may be of other types, and are not particularly limited herein.

Referring to fig. 1, the plurality of vibration dampers 112 may be divided into a first set of vibration dampers 1126 and a second set of vibration dampers 1128, and the housing 111 may include opposite first and second ends 1114, 1115. The first set of damping members 1126 may include a plurality of first damping members 1127, such as, for example, 2, 3, 4, 5, 6, or more, although not specifically illustrated herein, each first damping member 1127 coupled to the first end 1114. A first set of vibration dampeners 1126 is attached to the first end 1114, the first set of vibration dampeners 1126 may dampen vibrations of the first end 1114 of the housing 111.

Referring to fig. 1, in some embodiments, the first damping member 1127 may include one or more of a cylinder, a prism, and a sphere. For example, the first damping piece 1127 may be a cylindrical structure; for another example, the first damping piece 1127 may have a prism structure; for another example, the first damping piece 1127 may be a spherical structure; for another example, the first damping member 1127 may be a cylinder-to-sphere structure; for example, the first vibration damping member 1127 may be a cylinder, a prism, or a sphere; the structure of the first vibration damping member 1127 may be other structures, which are not listed here. In one example, the first damping member 1127 is formed in a spherical shape at a middle portion thereof, which is preferably deformed, and the first damping member 1127 is formed in a cylindrical shape at both end portions thereof so as to be coupled to the housing 111 and the snap member 113.

Further, referring to fig. 1, in some embodiments, the first vibration damping member 1127 may be a hollow structure, so that the first vibration damping member 1127 has a light weight, which may reduce the weight of the motor mounting bracket 11; meanwhile, the first vibration attenuating member 1127 of a hollow structure is more easily elastically deformed. In other embodiments, the first damping piece 1127 may be a solid structure to make the first damping piece 1127 more robust and less prone to breakage. In still other embodiments, the first damping member 1127 may be partially solid and partially hollow. The hollow structure may mean that a smaller cavity is arranged at a part, close to the center, of the first vibration damping member 1127, and the rest is solid; a hollow structure may also mean that a larger cavity is provided throughout the interior of the first vibration damping member 1127, so that the first vibration damping member 1127 is approximately a hollow structure; the hollow structure may also mean that the first vibration attenuating member 1127 is formed with a through hole on its axis so as to have a tubular structure as a whole.

Referring to fig. 1, in some embodiments, the plurality of first damping pieces 1127 may be located on the same cross section perpendicular to the axial direction of the housing 111. Specifically, the first vibration dampers 1127 are located at the first end 1114 of the housing 111 and distributed on the same ring perpendicular to the axial direction of the housing 111 to intensively damp vibrations at the same position of the first end 1114. For example, when the housing 111 is a cylinder, the first vibration dampers 1127 are all located on the same circumference of the first end 1114 of the housing 111. In other embodiments, the plurality of first vibration dampers 1127 are located on a plurality of different cross sections perpendicular to the axial direction of the housing 111, respectively. Specifically, the first plurality of damping members 1127 are each located at the first end 1114 of the housing 111 and are distributed on a plurality of rings perpendicular to the axial direction of the housing 111, respectively. It will be appreciated that the plurality of first damping members 1127 are offset to dampen vibrations at different circumferences of the first end 1114. For example, when the housing 111 is a cylinder, the first plurality of damping members 1127 are located on a plurality of different circumferences of the first end 1114 of the housing 111. In further embodiments, the first number of first damping pieces 1127 are located on one and the same first cross section perpendicular to the axial direction of the housing 111, i.e. the first number of first damping pieces 1127 are distributed on one and the same ring perpendicular to the axial direction of the housing 111; the second number of first damping pieces 1127 is located on the same second cross section perpendicular to the axial direction of the housing 111, i.e. the second number of first damping pieces 1127 is distributed over a number of different rings perpendicular to the axial direction of the housing 111.

More specifically, in some embodiments, the first vibration dampers 1127 are cylindrical or prismatic bodies having a central axis and an axis directed to the axis of the housing 111, in other words, the extending direction of the plurality of first vibration dampers 1127 is located in the radial direction of the cross-sectional circumference of the housing 111, while the first vibration dampers 1127 can axially expand and contract to damp the radial vibration of the housing 111, and the first vibration dampers 1127 can oscillate and deform in the extending direction of the housing 111 to damp the axial vibration of the housing 111. Of course, the housing 111 is not limited to a cylindrical structure, and may also be a prism or irregular structure, which is not limited herein. The central axis of the first vibration attenuating piece 1127 may be perpendicular to a tangential plane of a junction of the first vibration attenuating piece 1127 and the outer surface of the housing 111.

The axes of the plurality of first vibration dampers 1127 intersect the axis of the housing 111, and thus the plurality of first vibration dampers 1127 can damp the radial vibration generated from the housing 111. The projection of the motor mount 11 on the cross section perpendicular to the axial direction of the housing 111, the axes of the plurality of first vibration damping members 1127 may meet at the center point of the housing 111, and the included angle between the axes of two adjacent first vibration damping members 1127 may be the same or different, that is, the plurality of first vibration damping members 1127 may be uniformly or non-uniformly distributed outside the housing 111, so that the plurality of first vibration damping members 1127 may each dampen the radial vibration generated by the housing 111.

Referring to fig. 1, in some embodiments, a first damping member 1127 is removably coupled to the housing 111; for example, the first vibration attenuating member 1127 may be detachably attached to the housing 111 by means of a snap or screw connection, a screw connection, or the like, so that the first vibration attenuating member 1127 can be replaced in time when the first vibration attenuating member 1127 is aged or damaged. In other embodiments, the first damping piece 1127 is non-removably attached to the housing 111; for example, the first vibration damping member 1127 may be non-detachably connected to the housing 111 by welding, bonding, gluing, or injection molding, so that the connection between the first vibration damping member 1127 and the housing 111 is tighter and the first vibration damping member 1127 is not easily separated from the housing 111. In still other embodiments, the first vibration dampers 1127 may abut the outer wall 113 of the housing 111 without being fixedly connected thereto.

Referring to fig. 1, in some embodiments, the number of the first vibration damping members 1127 is three, and at least one of angles between center lines of adjacent first vibration damping members 1127 is greater than or equal to 120 degrees, so that the three first vibration damping members 1127 can fix the housing 111 and support the housing 111 well, so that the motor mount 11 can be mounted to an external structure more stably. Specifically, three adjacent included angles may exist between the three first vibration damping members 1127, for example, the three adjacent included angles are α 1, α 2 and α 3, respectively, at least one of α 1, α 2 and α 3 is greater than or equal to 120 degrees, for example, one of α 1, α 2 and α 3 is greater than or equal to 120 degrees, two of α 1, α 2 and α 3 are greater than or equal to 120 degrees, and α 1, α 2 and α 3 are all equal to 120 degrees.

Of course, in other embodiments, the number of the first damping members 1127 may be four, and at least one of the included angles between the center lines of the adjacent first damping members 1127 is greater than or equal to 90 degrees; the number of the first vibration damping members 1127 may be five, and at least one of the included angles between the center lines of the adjacent first vibration damping members 1127 is greater than or equal to 72 degrees; the number of the first vibration damping members 1127 may be six, and at least one of the included angles between the center lines of the adjacent first vibration damping members 1127 is greater than or equal to 60 degrees; the number of first damping pieces 1127 may also be other numbers, not listed here.

Referring to fig. 1, the second set of damping members 1128 may include a plurality of second damping members 1129, e.g., 2, 3, 4, 5, 6, or more, each second damping member 1129 coupled to the second end 1115. A second set of vibration dampening members 1128 are attached to the second end 1115, and the second set of vibration dampening members 1128 may dampen vibrations generated by the second end 1115 of the housing 111.

The first group of vibration dampers 1126 and the second group of vibration dampers 1128 are respectively arranged at the first end 1114 and the second end 1115 of the shell 111, so that vibration generated at two ends of the shell 111 can be weakened, the condition that the vibration of the other end of the shell 111 is large and even collides with an external structure when the vibration of the motor 12 is caused by the fact that the vibration dampers 112 are arranged at one end is avoided, and the condition that the vibration of the motor 12 causes the shell 111 to swing left and right and collide with the external structure to generate large noise when the vibration dampers 112 are arranged at the middle position of the shell 111 is also avoided. In other embodiments, the damping members 112 may be divided into more groups, for example, when the length of the motor 12 is longer, the housing 111 may have a problem of insufficient rigidity, which may result in excessive vibration in the middle area, and a group of damping members 112 may be added to the middle area of the housing 111.

The number of the first vibration attenuating members 1127 and the second vibration attenuating members 1129 may be the same or different. For example, when the motor 12 vibrates, the amplitude of the vibration of the second end 1115 of the housing 111 is greater than the amplitude of the vibration of the first end 1114 of the housing 111, and the number of the second vibration dampers 1129 may be greater than the number of the first vibration dampers 1127. And vice versa and will not be described in detail herein. Alternatively, the number of first and second damping

members

1127, 1129 may be the same to better balance the vibrations generated by the first and second ends 1114, 1115 of the housing 111.

The elastic deformation of the first and second damping

members

1127, 1129 may be different or the same when the motor 12 vibrates, and may be determined according to the vibration amplitudes of the first and second ends 1114, 1115 of the housing 111. Further, the lengths of the first and second damping

members

1127, 1129 may also be different, and may be determined by the distance between the first and second ends 1114, 1115 and the external structure.

Referring to fig. 1, in some embodiments, the second damping member 1129 may include one or more of a cylinder, a prism, and a sphere. For example, the second damping piece 1129 may be a cylindrical structure; for another example, the second vibration damping member 1129 may have a prism structure; for another example, the second damping piece 1129 may be a spherical structure; for another example, the second damping member 1129 may be a cylinder-to-sphere structure; for example, the second vibration damping member 1129 may be a cylinder, a prism, or a sphere; the structure of the second damping member 1129 may be other structures, which are not listed here. In one example, the second damping member 1129 is formed in a spherical shape at a middle portion thereof, which is preferably deformed, and the second damping member 1129 is formed in a cylindrical shape at both end portions thereof so as to be coupled to the housing 111 and the snap member 113. Wherein the second vibration attenuating piece 1129 and the first vibration attenuating piece 1127 may be identical in shape or different in shape.

Referring to fig. 1, in some embodiments, the second damping member 1129 may be a hollow structure, so that the second damping member 1129 may be light, and the weight of the motor mounting bracket 11 may be reduced; meanwhile, the second vibration attenuating member 1129 of a hollow structure is more easily elastically deformed. In other embodiments, the second damping member 1129 may be solid, such that the second damping member 1129 is more robust and less prone to breakage. In still other embodiments, the second damping member 1129 may be partially solid and partially hollow. The hollow structure may mean that a smaller cavity is arranged at a part, close to the center, of the second vibration damping member 1129, and the rest part is a solid structure; a hollow structure may also mean that a larger cavity is provided throughout the interior of the second vibration damping member 1129, so that the second vibration damping member 1129 is approximately a hollow structure; hollow may also mean that the second damping member 1129 is provided with a through hole on its axis so that it has a tubular structure as a whole.

Referring to fig. 1, in some embodiments, the second vibration dampers 1129 are located on the same cross section perpendicular to the axial direction of the housing 111. Specifically, the plurality of second vibration attenuating members 1129 are located at the second end 1115 of the housing 111 and are distributed on the same ring perpendicular to the axial direction of the housing 111, so that the plurality of second vibration attenuating members 1129 can concentrate and attenuate vibration generated at the same position of the second end 1115 of the housing 111. For example, when the housing 111 is cylindrical, the second damping members 1129 are all located on the same circumference of the second end 1115 of the housing 111. In other embodiments, the plurality of second vibration dampers 1129 are located on a plurality of different cross-sections perpendicular to the axial direction of the housing 111, respectively. Specifically, a plurality of second damping members 1129 are each located at the second end 1115 of the housing 111 and are distributed on a plurality of rings perpendicular to the axial direction of the housing 111, respectively. It is understood that the plurality of second damping members 1129 are disposed in a staggered manner, and the plurality of second damping members 1129 may damp vibrations on different circumferences of the second end 1115 of the housing 111, respectively. For example, when the housing 111 is cylindrical, the second plurality of damping members 1129 are located on a plurality of different circumferences of the second end 1115 of the housing 111. In further embodiments, the first number of second damping pieces 1129 is located on one and the same first cross section perpendicular to the axial direction of the housing 111, i.e. the first number of first damping pieces 1127 are distributed on one and the same ring perpendicular to the axial direction of the housing 111; the second number of second damping pieces 1129 is located on the same second cross section perpendicular to the axial direction of the housing 111, i.e. the second number of first damping pieces 1127 is distributed over a number of different rings perpendicular to the axial direction of the housing 111.

More specifically, in some embodiments, the second vibration dampers 1129 are cylindrical or prismatic bodies having a central axis and having an axis directed toward the axis of the housing 111, in other words, the extending direction of the plurality of second vibration dampers 1129 is located in the radial direction of the cross-sectional circumference of the housing 111, while the second vibration dampers 1129 may damp radial vibration of the housing 111 in an axially telescopic manner and the second vibration dampers 1129 may damp axial vibration of the housing 111 in an oscillating manner. Of course, the housing 111 is not limited to a cylindrical structure, and may also be a prism or irregular structure, which is not limited herein. The central axis of the second vibration attenuating piece 1129 may be perpendicular to a tangential plane of a point where the central axis of the second vibration attenuating piece 1129 meets the outer surface of the housing 111.

The axes of the plurality of second vibration attenuating members 1129 intersect the axis of the housing 111, and thus the plurality of second vibration attenuating members 1129 may attenuate radial vibration generated from the housing 111. The projection of the motor mount 11 on the cross section perpendicular to the axial direction of the housing 111, the axes of the plurality of second vibration damping members 1129 may meet at the center point of the housing 111, and the included angle between the axes of two adjacent second vibration damping members 1129 may be the same or different, that is, the plurality of second vibration damping members 1129 may be uniformly or non-uniformly distributed outside the housing 111, so that the plurality of second vibration damping members 1129 may each dampen the radial vibration generated by the housing 111.

Referring to fig. 1, in some embodiments, the second damping member 1129 is removably coupled to the housing 111. For example, the second vibration damping member 1129 may be detachably attached to the housing 111 by means of a snap, a screw connection, a bolt connection, or the like, so that the second vibration damping member 1129 can be replaced in time when the second vibration damping member 1129 is aged or damaged. In other embodiments, the second damping piece 1129 is non-removably attached to the housing 111. For example, the second vibration damping member 1129 may be non-detachably connected to the housing 111 by welding, bonding, gluing, or injection molding, so that the connection between the second vibration damping member 1129 and the housing 111 is tighter and the second vibration damping member 1129 is not easily separated from the housing 111. In still other embodiments, the second vibration damping member 1129 may abut the outer wall 113 of the housing 111 without being fixedly connected thereto.

Referring to fig. 1, in some embodiments, the number of the second vibration damping members 1129 is three, and at least one of angles between center lines of adjacent second vibration damping members 1129 is greater than or equal to 120 degrees, so that the three second vibration damping members 1129 can fix the housing 111 and support the housing 111 well, so that the motor mount 11 can be mounted to an external structure more stably. Specifically, three adjacent included angles may exist between the three second vibration damping members 1129, for example, the three adjacent included angles are β 1, β 2 and β 3, at least one of β 1, β 2 and β 3 is greater than or equal to 120 degrees, two of β 1, β 2 and β 3 are greater than or equal to 120 degrees, and β 1, β 2 and β 3 are all equal to 120 degrees.

Of course, in other embodiments, the number of the second damping members 1129 may be four, and at least one of the included angles between the center lines of the adjacent second damping members 1129 is greater than or equal to 90 degrees; the number of the second vibration damping members 1129 may be five, and at least one of the included angles between the center lines of the adjacent second vibration damping members 1129 is greater than or equal to 72 degrees; the number of the second vibration damping members 1129 may be six, and at least one of the included angles between the center lines of the adjacent second vibration damping members 1129 is greater than or equal to 60 degrees; the number of second damping members 1129 may also be other numbers, not listed here.

In some embodiments, any one of the first vibration attenuating pieces 1127 and any one of the second vibration attenuating pieces 1129 are disposed in a displaced manner in the axial direction of the housing 111. In particular, at least one first damping piece 1127 is located between two adjacent second damping pieces 1129, or there is a first damping piece 1127 located between two adjacent second damping pieces 1129, as projected in the axial direction of the housing 111. In this way, the first damping piece 1127 and the second damping piece 1129 can be mutually matched to play a role of damping vibration in multiple directions.

In other embodiments, a plurality of first vibration attenuating pieces 1127 and a plurality of second vibration attenuating pieces 1129 are aligned in the axial direction of the housing 111, respectively. It can be understood that the first and second

vibration attenuating members

1127 and 1129 are equal in number, and each first vibration attenuating member 1127 and each second vibration attenuating member 1129 are aligned in a projection in the axial direction of the housing 111, so that the first and second groups of

vibration attenuating members

1126 and 1128 can achieve better vibration attenuating performance. In the embodiment shown in fig. 1, a plurality of first vibration damping members 1127 and a plurality of second vibration damping members 1129 are arranged in alignment in the axial direction of the housing 111, respectively.

Referring to fig. 1, the number of the clamping members 113 may be multiple, each clamping member 113 is connected to an end of the damping member 112 far away from the casing 111, and the clamping members 113 may be detachably connected to an external structure (for example, the sleeve 32 of the drying device 100 shown in fig. 7), so that the motor mounting bracket 11 may be detachably mounted to the external structure. Specifically, the number of the snap members 113 may be the same as the number of the vibration damping members 112, that is, one snap member 113 is connected to each vibration damping member 112. The clamping member 113 can be clamped to an external structure, and the clamping member 113 can also be connected with the external structure through a screw.

The clip 113 may be made of silicon, rubber, plastic, or metal, which are not listed here. In some embodiments, the material of the snap member 113 is different from the material of the vibration damping member 112, and the snap member 113 is made of a hard material, such as plastic, metal, etc., so that the snap member 113 can be more firmly connected with the external structure, and the snap member 113 is not easily separated from the external structure when the motor 12 vibrates. In some embodiments, the material of the clip 113 is the same as the material of the housing 111, e.g., the clip 113 and the housing 111 are both made of plastic.

Referring to fig. 1, the clamping member 113 and the damping member 112 may be an integral structure, for example, the clamping member 113 and the damping member 112 may be integrally formed by a two-shot molding process. The clamping piece 113 and the vibration damping piece 112 can also be of a split structure, and the clamping piece 113 and the vibration damping piece 112 are assembled together in a welding or bonding mode and the like.

Referring to fig. 1, the clip 113 may include a body 1131 and a clip protrusion 1132 extending from the body 1131 away from the housing 111, and the clip protrusion 1132 may be used to connect with an external structure. Body 1131 may be coupled to damping member 112, and body 1131 and snap tab 1132 may be integrally formed. The clamping protrusion 1132 may be hook-shaped, so that the clamping protrusion 1132 may clamp an external structure and may not be easily separated from the external structure. The clamping protrusion 1132 may also extend into a clamping hole (e.g., the clamping hole 3212 shown in fig. 7) of the external structure to clamp the external structure. In some embodiments, body 1131 can slide into a catch of the external structure (e.g., catch hole 3211 shown in fig. 7), which can catch body 1131, such that body 1131 cannot easily disengage from the catch slot.

Referring to fig. 1, the plurality of clips 113 can be divided into a first set of clips 1133 and a second set of clips 1135. The first set of clamping members 1133 may include a plurality of first clamping members 1134, the number of the first clamping members 1134 may be the same as the number of the first vibration reduction members 1127, the plurality of first clamping members 1134 are connected to the plurality of first vibration reduction members 1127 in a one-to-one correspondence, and the first clamping members 1134 are used for fixing the first end 1114 of the housing 111 to an external structure. The first clamping member 1134 may be made of a hard material, for example, the first clamping member 1134 may be made of a hard plastic or a metal, so that the first clamping member 1134 may have a stronger hardness, and further the first clamping member 1134 may be more stably connected to an external structure, and the first clamping member 1134 is not easily separated from the external structure when the motor 12 vibrates.

Referring to fig. 1, in some embodiments, the first clamping member 1134 and the first vibration damping member 1127 are an integral structure, for example, the first clamping member 1134 and the first vibration damping member 1127 may be manufactured into an integral structure through two-shot injection molding, two-shot injection molding (two-material injection molding), secondary molding, or casting, so that the first clamping member 1134 and the first vibration damping member 1127 are not easily broken, and the stability of the motor mounting bracket 11 is better. In other embodiments, the first clamping member 1134 and the first vibration damping member 1127 may be separate structures, and the first clamping member 1134 and the first vibration damping member 1127 may be assembled together by welding, bonding, clamping, or the like, so that the manufacturing process is simpler.

Further, in some embodiments, the first clamping member 1134, the first vibration damping member 1127 and the housing 111 may be integrally formed, that is, the first clamping member 1134, the first vibration damping member 1127 and the housing 111 may be manufactured as an integral structure by two-shot molding, two-shot molding (two-shot molding), three-shot molding, injection molding, or the like. Therefore, the first vibration damping piece 1127 is not easily separated from the housing 111, the first clamping piece 1134 is not easily separated from the first vibration damping piece 1127, and even if the motor 12 violently vibrates the first clamping piece 1134, the first vibration damping piece 1127 and the housing 111, the first clamping piece 1134, the first vibration damping piece 1127 and the housing 111 are not easily separated.

Referring to fig. 1, the second set of clamping members 1135 may include a plurality of second clamping members 1136, and each second clamping member 1136 may be connected to one second vibration damping member 1129. The number of second snap members 1136 may be the same as the number of second vibration dampers 1129, and the second snap members 1136 are used to fix the second end of the housing 111 to an external structure. Through first group joint spare 1133 and second group joint spare 1135 for the both ends of casing 111 all can be fixed on exterior structure, are convenient for first group damping spare 1126 and second group damping spare 1128 to realize the damping performance better.

Further, in some embodiments, the second clamping member 1136 and the second vibration damping member 1129 are integrally formed, for example, the second clamping member 1136 and the second vibration damping member 1129 may be manufactured as an integral structure by two-shot molding, two-shot molding (two-shot injection molding), or two-shot molding, so that the second clamping member 1136 and the second vibration damping member 1129 are not easily broken, and the stability of the motor mounting bracket 11 is better. In other embodiments, the second clamping member 1136 and the second vibration damping member 1129 may be separate structures, and the second clamping member 1136 and the second vibration damping member 1129 may be assembled together by welding, bonding, clamping, and the like, so that the manufacturing process is simpler.

Still further, in some embodiments, the second clamping member 1136, the second vibration damping member 1129 and the housing 111 may be an integral structure, that is, the second clamping member 1136, the second vibration damping member 1129 and the housing 111 may be manufactured as an integral structure by two-color injection molding, three-time molding or the like. Therefore, the second vibration damping pieces 1129 are not easy to separate from the shell 111, the second clamping pieces 1136 are not easy to separate from the second vibration damping pieces 1129, and the motor mounting frame 11 can better reduce vibration and noise.

Referring to fig. 1 and 4, the motor 12 can generate an airflow when rotating, in some embodiments, the motor mounting bracket 11 may further include a bracket 114, the bracket 114 may be mounted at an end of the housing 111 and located downstream of the airflow flowing in the housing 111, the bracket 114 may have a circulation chamber 1141 communicating with the receiving chamber 1111, one end of the bracket 114 may have a shielding portion 1142, and the shielding portion 1142 may shield at least a portion of a gap between the bracket 114 and an external structure (e.g., an inner wall 201 of the duct 20) to prevent a portion of the airflow in the circulation chamber 1141 from flowing into the gap. Therefore, no air flow or less air flow can flow into the gap, and the phenomenon that more air flow flows into the gap and circles in the gap to generate larger noise is avoided.

Specifically, after the motor 12 is installed in the receiving cavity 1111, the airflow generated by the motor 12 flows from the first end 1114 to the second end 1115 of the housing 111, and the bracket 114 can be fixedly installed or detachably connected to the end of the second end 1115 of the housing 111. The support 114 may be hollow such that the support 114 forms a flow-through chamber 1141 and the airflow generated by the motor 12 may enter the flow-through chamber 1141 and exit the flow-through chamber 1141. The end of the bracket 114 remote from the housing 111 may be provided with a shield 1142, and the shield 1142 may be disposed around the flow-through chamber 1141 such that the shield 1142 may circumferentially seal at least part of the gap between the bracket 114 and the external structure. For example, the shield portion 1142 may circumferentially seal a portion of the gap between the bracket 114 and the external structure, or the shield portion 1142 may circumferentially seal the entire gap between the bracket 114 and the external structure.

Further, since the bracket 114 is connected to the housing 111, and the motor 12 is installed in the housing 111, the vibration generated when the motor 12 rotates can be transmitted to the bracket 114, and then the bracket 114 is driven to vibrate, so that the bracket 114 transmits the vibration to the external structure, and the external structure vibrates together. In order to attenuate the vibration transmitted from the bracket 114 to the external structure, the shielding portion 1142 may be elastically deformed such that the shielding portion 1142 may buffer the vibration generated from the bracket 114, and thus the vibration transmitted to the external structure (e.g., the drying apparatus 100) when the motor 12 rotates is reduced, or even no vibration is transmitted to the external structure (e.g., the drying apparatus 100). In one example, the shielding portion 1142 may be made of a soft material, such as silicon gel or rubber, so that the shielding portion 1142 has a better buffering performance and can be elastically deformed.
