Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] The garment processing apparatus 1 according to an embodiment of the present application is described below with reference to Figures 1-14.

[0027] As shown in Figure 1, the garment processing device 1 according to this application includes: an outer cylinder 10, a vibration damping structure 20, and a buffer rod 30. One end of the vibration damping structure 20 is hinged to the outer cylinder 10 and is configured as a plurality of spaced-apart structures. The buffer rod 30 connects at least two vibration damping structures 20. In some embodiments, when the garment processing device 1 is in operation, the outer cylinder 10 vibrates, and the vibration generates noise. The vibration damping structure 20 connected to the outer cylinder 10 can reduce the vibration amplitude of the outer cylinder 10, thereby reducing the noise transmitted to the outside of the garment processing device 1. When there are multiple vibration damping structures 20, the multiple vibration damping structures 20 are connected to different positions on the garment processing device 1, and the vibration damping amplitude of each vibration damping structure 20 may be different. Therefore, the buffer rod 30 is designed. The buffer rod 30 is disposed on the outer cylinder 10 and connected to at least two vibration damping structures 20. The buffer rod 30 can balance the vibration between the at least two vibration damping structures 20 connected to it, reducing the noise transmitted to the outside of the garment processing device 1.

[0028] According to the present application, the garment processing device 1 is provided with a buffer rod 30 to connect at least two vibration damping structures 20. By adding a connection between at least two vibration damping structures 20, the stiffness between the vibration damping structures 20 can be increased, and the buffer rod 30 can balance the vibration between the at least two vibration damping structures 20 connected to it, reduce the eccentricity of the outer cylinder 10, thereby reducing vibration noise and improving the user experience.

[0029] According to some embodiments of this application, the buffer rod 30 connects at least two vibration damping structures 20 to the outer cylinder 10. Multiple vibration damping structures 20 are spaced apart on the outer periphery of the outer cylinder 10. Both ends of the buffer rod 30 are connected to two vibration damping structures 20 respectively to balance the vibration of the two vibration damping structures 20 connected to the buffer rod 30. Through the connection between the buffer rod 30 and the outer cylinder 10, the vibration amplitude of the vibration damping structures 20 connected to the buffer rod 30 relative to the outer cylinder 10 can be reduced, further reducing the noise transmitted to the outside of the garment processing equipment 1.

[0030] According to some embodiments of this application, as shown in FIG1, multiple vibration damping structures 20 are spaced apart on the outer periphery of the outer cylinder 10. The two ends of a buffer rod 30 are respectively connected to two vibration damping structures 20 to balance the vibration of the two vibration damping structures 20 connected to the buffer rod 30. In some embodiments, the vibration damping structures 20 are disposed on the outer surface of the outer cylinder 10, and the buffer rod 30 can also be disposed on the outer surface of the outer cylinder 10 and connected to the outer cylinder 10. The buffer rod 30 is connected to two vibration damping structures 20 to balance the vibration of these two vibration damping structures 20. Here, both the buffer rod 30 and the vibration damping structures 20 can be constructed in multiples. Two vibration damping structures 20 and one buffer rod 30 constitute a set of vibration damping components. At least one set of vibration damping components can be disposed on the outer periphery of the outer cylinder 10 to reduce the vibration amplitude of the outer cylinder 10, thereby reducing the noise generated by the vibration.

[0031] In some embodiments, a plurality of vibration damping structures 20 may be arranged at intervals along the axial and / or circumferential direction of the outer cylinder 10, and the buffer rod 30 connects any two vibration damping structures 20.

[0032] According to some embodiments of this application, as shown in FIG2, the buffer rod 30 includes a rod body 31 and a buffer portion 320. The rod body 31 is connected to the outer cylinder 10. The buffer portion 320 is disposed at both ends of the rod body 31 and is respectively connected to two vibration damping structures 20. The buffer portion 320 is constructed as a flexible component. It can be understood that when the outer cylinder 10 vibrates, the outer cylinder 10 transmits the force to the connected vibration damping structure 20 and buffer rod 30. At this time, there is a risk of deformation under stress at the connection between the vibration damping structure 20 and the buffer rod 30. Therefore, the part connecting the vibration damping structure 20 and the buffer rod 30 is designed as a flexible structure. The deformation of the flexible structure can absorb the force at the connection between the vibration damping structure 20 and the buffer rod 30, thereby attenuating the vibration amplitude between the vibration damping structure 20 and the buffer rod 30 and achieving vibration reduction. Here, the rod body 31 of the buffer rod 30 is connected to the outer cylinder 10, and the buffer part 320 of the buffer rod 30 is connected to the vibration damping structure 20. The buffer part 320 is constructed as a flexible component to absorb the vibration energy between the vibration damping structure 20 and the rod body 31, and to attenuate the vibration amplitude between the vibration damping structure 20 and the rod body 31, thereby achieving vibration reduction.

[0033] According to some embodiments of this application, as shown in FIG13, the vibration damping structure 20 includes a support rod 21 and a connecting part 221. One end of the support rod 21 is hinged to the outer cylinder 10. The connecting part 221 is disposed on the support rod 21 and is adapted to be connected to the buffer part 320. The connecting part 221 is provided with a first mounting hole 221a, and the buffer part 320 is provided with a second mounting hole 32a. The fixing member 33 passes through the first mounting hole 221a and the second mounting hole 32a to connect the connecting part 221 and the buffer part 320.

[0034] In some embodiments, the garment processing device 1 further includes a housing with an installation cavity formed inside. An outer cylinder 10 is disposed within the installation cavity. One end of a support rod 21 is hinged to the outer cylinder 10, and the other end of the support rod 21 is hinged to the inner wall of the installation cavity. When the outer cylinder 10 vibrates, the support rod 21 rotates slightly about the end hinged to the inner wall of the installation cavity. A buffer rod 30 connects the two support rods 21 and the outer cylinder 10, which can reduce the rotation amplitude of the two support rods 21, thereby reducing the vibration amplitude of the vibration damping structure 20 and reducing the noise transmitted to the outside of the garment processing device 1. Here, a connecting portion 221 is provided on the support rod 21 to connect with the buffer portion 320 of the buffer rod 30. The buffer portion 320 can attenuate the vibration amplitude between the connecting portion 221 and the rod 31, thereby achieving vibration reduction.

[0035] According to some embodiments of this application, as shown in Figures 3 and 8, the connecting portion 221 is provided with a first mounting hole 221a, and the buffer portion 320 is provided with a second mounting hole 32a. The fixing member 33 passes through the first mounting hole 221a and the second mounting hole 32a to connect the connecting portion 221 and the buffer portion 320. It can be understood that the fixing member 33 may only be used to connect the connecting portion 221 and the buffer portion 320. The connecting portion 221 and the buffer portion 320 may be fixed by other structural members. Alternatively, the connecting portion 221 and the buffer portion 320 may be fixedly connected by the fixing member 33 without the participation of other structural members. Here, the fastener 33 can pass through the first mounting hole 221a and the second mounting hole 32a and be threaded into the first mounting hole 221a and / or the second mounting hole 32a to achieve the connection between the fastener 33 and the connecting part 221 and the buffer part 320. Alternatively, the fastener 33 can pass through the first mounting hole 221a and the second mounting hole 32a and be fastened to other structural components to achieve the connection between the fastener 33 and the connecting part 221 and the buffer part 320.

[0036] According to some embodiments of this application, as shown in FIG3, the first mounting hole 221a and the second mounting hole 32a have the same shape. The shape of the fastener 33 is adapted to the shape of the first mounting hole 221a. The first mounting hole 221a is constructed as a non-circular hole. When the connecting part 221 and the buffer part 320 have a tendency to rotate relative to each other, the fastener 33 will abut against the hole walls of the first mounting hole 221a and the second mounting hole 32a, restricting the relative rotation of the connecting part 221 and the buffer part 320, and transmitting the force to the buffer part 320, so that the buffer part 320 attenuates the force transmitted to the buffer rod 30, thereby ensuring the connection stability of the connecting part 221 and the buffer part 320, reducing the probability of vibration caused by the relative movement of the connecting part 221 and the buffer part 320, and thus reducing the noise generated by the connection of the connecting part 221 and the buffer part 320.

[0037] In some embodiments, non-circular holes may refer to polygonal holes such as triangular holes, quadrilateral holes (as shown in Figure 3), pentagonal holes, etc., or elliptical holes or other irregularly shaped holes. The shape of the fastener 33 is sufficient to abut against the hole walls of the first mounting hole 221a and the second mounting hole 32a when the connecting part 221 and the buffer part 320 have a tendency to rotate relative to each other, so as to limit the relative rotation of the connecting part 221 and the buffer part 320 and ensure the connection stability of the connecting part 221 and the buffer part 320.

[0038] According to some embodiments of this application, as shown in Figures 3-5, the rod 31 includes a first rod segment 311 and a second rod segment 312. The first rod segment 311 is connected to the outer cylinder 10. The second rod segment 312 is constructed as two segments and is respectively disposed at both ends of the first rod segment 311. The second rod segment 312 is movably engaged with the first rod segment 311, and the end of the second rod segment 312 away from the first rod segment 311 is connected to the buffer portion 320. It is understandable that, since the buffer rod 30 is fixedly connected to the outer cylinder 10, when the outer cylinder 10 vibrates, there is relative movement between the buffer rod 30 and the support rod 21. In order to avoid the buffer rod 30 or the support rod 21 being subjected to excessive force and thus breaking due to the relative movement between the buffer rod 30 and the support rod 21, the rod body 31 of the buffer rod 30 is designed as a multi-segment structure that can move relatively. In some embodiments, the first segment 311 is fixedly connected to the outer cylinder 10, and the two second segments 312 are respectively movably engaged with the two ends of the first segment 311. The two second segments 312 are also respectively connected to the connecting parts 221 of the two vibration damping structures 20. When the outer cylinder 10 vibrates, there is relative movement between the first segment 311 connected to the outer cylinder 10 and the second segment 312 connected to the connecting part 221. The design of the first segment 311 and the second segment 312 can provide displacement margin for the connection between the buffer rod 30 and the support rod 21, and prevent the buffer rod 30 or the support rod 21 from breaking due to excessive force when they move relative to each other.

[0039] According to some embodiments of this application, as shown in Figures 3-5, a first rod segment 311 extends in a first direction and both ends of the first rod segment 311 form an installation channel 311a extending in the first direction. One end of a second rod segment 312 is movably disposed within the installation channel 311a, and the other end of the second rod segment 312 is connected to a buffer portion 320. As shown in Figure 5, the second rod segment 312 includes a connecting rod portion 3121. One end of the connecting rod portion 3121 is movably disposed within the installation channel 311a, and the other end of the connecting rod portion 3121 has a connecting channel 3121a in a second direction, which is orthogonal to the first direction. As shown in Figure 8, the buffer portion 320 includes a first buffer member 32. The first buffer member 32 is disposed within the connecting channel 3121a and has a second mounting hole 32a. The first buffer member 32 is disposed between the fixing member 33 and the inner wall of the connecting channel 3121a.

[0040] Here, since the support rod 21 and the outer cylinder 10 are connected by a pin, the outer cylinder 10 will sink after a load is applied, and the relative positions of the support rods 21 on both sides will change. In order to ensure that the middle rod 31 is not pulled, the rod 31 needs to include at least two segments that can move relative to each other. The first rod segment 311 is designed to have installation channels 311a extending in the first direction at both ends, so that the second rod segment 312 can move in the first direction after being set in the installation channel 311a, thus avoiding the rod 31 being pulled.

[0041] According to some embodiments of this application, as shown in FIG5, the second rod segment 312 includes a connecting rod portion 3121, one end of which is movably disposed in the mounting channel 311a, and the other end of which is provided with a connecting channel 3121a in a second direction, the second direction being orthogonal to the first direction; as shown in FIG8, the buffer portion 320 includes a first buffer member 32, which is disposed in the connecting channel 3121a and has a second mounting hole 32a, and is disposed between the fixing member 33 and the inner wall of the connecting channel 3121a. In some embodiments, the connecting rod portion 3121 of the second rod segment 312 is movably engaged with the first rod segment 311. Simultaneously, the connecting rod portion 3121 is also connected to the connecting portion 221 of the support rod 21. To absorb the vibration energy between the connecting rod portion 3121 and the connecting portion 221, a first buffer 32 is provided between the connecting rod portion 3121 and the connecting portion 221. When the connecting rod portion 3121 and the connecting portion 221 move relative to each other, the flexible first buffer 32 can be compressed, thereby attenuating the force transmitted between the connecting portion 221 and the connecting rod portion 3121, ensuring the connection stability of the connecting portion 221 and the connecting rod portion 3121, reducing the probability of vibration caused by relative movement of the connecting portion 221 and the connecting rod portion 3121, and thus reducing the noise generated by the connection of the connecting portion 221 and the connecting rod portion 3121.

[0042] Here, since the first mounting hole 221a is a non-circular hole, after the fixing member 33 connects the connecting rod part 3121 and the connecting part 221, the connecting rod part 3121 and the connecting part 221 will not rotate relative to each other. Furthermore, the fixing member 33 and the connecting rod part 3121 cooperate in the second direction, which can also prevent the connecting rod part 3121 from rotating relative to the connecting part 221, thereby further improving the connection stability between the connecting rod part 3121 and the connecting part 221.

[0043] According to some embodiments of this application, the end of the connecting rod portion 3121 with the connecting channel 3121a is adapted to face the connecting portion 221. At least a portion of the first buffer member 32 is disposed between the end of the connecting rod portion 3121 with the connecting channel 3121a and the connecting portion 221. In this case, the aforementioned at least a portion of the first buffer member 32 can be used to buffer the vibration between the connecting rod portion 3121 and the connecting portion 221, improve the energy absorption effect of the first buffer member 32 on the vibration between the connecting portion 221 and the connecting rod portion 3121, and improve the noise reduction effect while reducing the stiffness of the fit between the connecting portion 221 and the connecting rod portion 3121.

[0044] In some embodiments, as shown in FIG7, the connecting portion 221 has an installation space 2213b inside, and the surface of the connecting portion 221 in the second direction has a first installation hole 221a communicating with the installation space 2213b. The connecting portion 221 also has an opening 2213a open in the first direction, which communicates with the installation space 2213b and is suitable for the second limiting portion to be installed into the installation space 2213b through the opening 2213a. Here, the connecting part 221 includes a first plate 2211, a second plate 2212, and a connecting plate 2213. The first plate 2211 and the second plate 2212 are spaced apart in the circumferential direction and are directly opposite and parallel in the second direction. Both the first plate 2211 and the second plate 2212 have a first mounting hole 221a. The connecting plate 2213 extends in the second direction and connects to the first plate 2211 and the second plate 2212 respectively. The connecting plate 2213, the first plate 2211, and the second plate 2212 together define an installation space 2213b. The connecting plate 2213 has an opening 2213a. A first buffer member 32 is disposed in the connecting channel 3121a. The first buffer member 32 has a second mounting hole 32a suitable for the fastener 33 to pass through. The first buffer member 32 is disposed between the fastener 33 and the inner wall of the connecting channel 3121a.

[0045] According to some embodiments of this application, as shown in FIG8, at least one end of the first buffer member 32 is formed with an outer edge 321. The outer edge 321 protrudes from the outer surface of the first buffer member 32. The projection of the first buffer member 32 in the second direction is located within the projection of the outer edge 321 in the second direction. The outer edge 321 is disposed between the end of the connecting rod portion 3121 where the connecting channel 3121a is opened and the connecting portion 221. The first buffer 32 is disposed between the fixing member 33 and the connecting channel 3121a to buffer the vibration between the fixing member 33 and the connecting rod 3121. The outer edge 321 provided on the first buffer 32 is located between the connecting rod 3121 and the first plate 2211 and / or the second plate 2212 to buffer the vibration between the connecting rod 3121 and the first plate 2211 and / or the second plate 2212. This improves the energy absorption effect of the first buffer 32 on the vibration between the connecting part 221 and the connecting rod 3121, and can improve the noise reduction effect while reducing the stiffness of the fit between the connecting part 221 and the connecting rod 3121.

[0046] According to some embodiments of this application, as shown in FIG8, the cross-sectional shape of the first buffer 32 perpendicular to the second direction is consistent with the cross-sectional shape of the connecting channel 3121a perpendicular to the second direction, and the cross-sectional shape of the connecting channel 3121a perpendicular to the second direction is non-circular. In some embodiments, referring to FIG3, when the connecting portion 221 and the buffer portion 320 have a tendency to rotate relative to each other, the inner wall surface of the first buffer 32 will abut against the outer surface of the fixing member 33 to restrict the rotation of the first buffer 32 relative to the fixing member 33. At this time, the inner wall surface of the connecting channel 3121a will abut against the outer surface of the first buffer 32 to restrict the rotation of the connecting rod portion 3121 relative to the first buffer 32. At the same time, the inner wall surface of the first mounting hole 221a will abut against the outer surface of the fixing member 33 to restrict the rotation of the connecting portion 221 relative to the fixing member 33. The structure of the first buffer 32 is designed such that the connecting part 221 and the connecting rod part 3121 remain relatively fixed, and the connecting part 221 and the connecting rod part 3121 will not rotate relative to each other. Furthermore, when the connecting part 221 and the connecting rod part 3121 have a tendency to rotate, the first buffer 32 can attenuate the force transmitted from the connecting part 221 and the connecting rod part 3121 to each other through deformation, thereby ensuring the connection stability of the connecting part 221 and the connecting rod part 3121, reducing the probability of vibration caused by the relative movement of the connecting part 221 and the connecting rod part 3121, and thus reducing the noise generated by the connection of the connecting part 221 and the connecting rod part 3121.

[0047] The non-circular shape mentioned here can refer to polygons such as triangles, quadrilaterals (as shown in Figure 3), pentagons, etc., or it can refer to ellipses or other irregular shapes. The shape of the first buffer 32 should be able to abut against the fixing member 33 and the connecting rod 3121 when the connecting part 221 and the connecting rod 3121 have a tendency to rotate relative to each other, so as to limit the relative rotation of the connecting part 221 and the connecting rod 3121 and ensure the connection stability of the connecting part 221 and the connecting rod 3121.

[0048] According to some embodiments of this application, as shown in Figures 5-6, a second buffer 34 is provided at one end of the connecting rod portion 3121. The second buffer 34 is movably housed within the mounting channel 311a and is adapted to attenuate the vibration between the connecting rod portion 3121 and the first rod segment 311. The connecting rod portion 3121 is adapted to slide within the mounting channel 311a. The second buffer 34 can attenuate the vibration between the connecting rod portion 3121 and the inner wall of the mounting channel 311a. Furthermore, the force transmitted between the connecting rod portion 3121 and the first rod segment 311 is absorbed by the second buffer 34. Providing the second buffer 34 can ensure the connection stability between the connecting rod portion 3121 and the first rod segment 311, reduce the probability of vibration caused by relative movement between the connecting rod portion 3121 and the first rod segment 311, and thereby reduce the noise generated by the connection between the connecting rod portion 3121 and the first rod segment 311.

[0049] In some embodiments, as shown in Figures 2, 5, and 6, a second buffer member 34 is sleeved on the connecting rod portion 3121. At least one end of the second buffer member 34 is formed with a flange 341, which protrudes from the outer surface of the second buffer member 34. The axial projection of the second buffer member 34 is located within the axial projection of the flange 341. The flange 341 is adapted to abut against the end face of the connecting rod that forms a connecting channel 3121a, so as to limit the displacement of the connecting rod portion 3121 relative to the first rod segment 311 and prevent the connecting rod portion 3121 from disengaging from the mounting channel 311a of the first rod segment 311.

[0050] According to some embodiments of this application, as shown in Figures 2, 3, and 9, the garment processing device 1 further includes a retaining buckle 35. The retaining buckle 35 has a groove 3531a formed on it, suitable for accommodating a portion of the first rod segment 311. The retaining buckle 35 is adapted to be fixedly connected to the outer cylinder 10 to connect the first rod segment 311 to the outer cylinder 10. Here, the connection between the first rod segment 311 and the outer cylinder 10 can be either that the first rod segment 311 is directly fixed to the outer cylinder 10, or that the first rod segment 311 is fixed to the outer cylinder 10 via the retaining buckle 35, with the first rod segment 311 engaging with the groove 3531a formed on the retaining buckle 35.

[0051] According to some embodiments of this application, as shown in FIG9, a protrusion 3531 protruding to one side is formed on the retaining buckle 35, and a groove 3531a is formed on the other side of the retaining buckle 35, which is adapted to receive the first rod segment 311. In some embodiments, the retaining buckle 35 can be formed by stamping sheet metal, which facilitates the process design of the retaining buckle 35. Here, the sheet metal is stamped and a protrusion 3531 is formed on one side of the retaining buckle 35 in the thickness direction, and a groove 3531a corresponding to the protrusion 3531 is formed on the other side of the retaining buckle 35 in the thickness direction.

[0052] According to some embodiments of this application, as shown in FIG3, the garment processing device 1 further includes a third buffer 36, which is disposed between the groove 3531a and the first rod segment 311 to attenuate the vibration between the outer cylinder 10 and the first rod segment 311. In some embodiments, the third buffer 36 may be sleeved on at least part of the outer periphery of the first rod segment 311. When the outer cylinder 10 vibrates, the first rod segment 311 may move relative to the fixing buckle 35, causing vibration between the fixing buckle 35 and the first rod segment 311. At this time, the third buffer 36 can buffer the vibration between the fixing buckle 35 and the first rod segment 311, thereby attenuating the vibration between the outer cylinder 10 and the first rod segment 311.

[0053] In the above embodiment, a first buffer 32 is provided at the end where the second rod segment 312 is connected to the support rod 21, a second buffer 34 is provided at the part where the first rod segment 311 is connected to the second rod segment 312, and a third buffer 36 is provided at the part where the first rod segment 311 is connected to the outer cylinder 10. It can be seen that structural components such as the first buffer 32, the second buffer 34, and the third buffer 36 used for energy absorption can be set at the position where the rod body 31 is subjected to greater force, or at the connection between two structures, in order to reduce the stiffness of the fit between the two structures. Furthermore, the force between the two structures can be transmitted to the energy-absorbing structural component, and the compression of the energy-absorbing structural component will also increase, making the energy-absorbing structural component have a better energy absorption and vibration reduction effect.

[0054] In some embodiments, the performance of the energy-absorbing structure must meet the requirement that, at a position where the rod 31 is subjected to a constant vibration frequency, the damping factor of the energy-absorbing structure is ≥0.8.

[0055] According to some embodiments of this application, as shown in FIG4, the first rod segment 311 includes at least a first rod body 3111, a first bent rod 3112, and a second rod body 3113. The first rod body 3111 extends in a first direction and forms an installation channel 311a; the first bent rod 3112 extends in a second direction, and one end of the first bent rod 3112 is connected to the first rod body 3111; the second rod body 3113 is arranged parallel to the first rod body 3111 and located at at least one end of the first rod body 3111 in the first direction, and one end of the second rod body 3113 is connected to the other end of the first bent rod 3112.

[0056] In some embodiments, the two ends of the first rod segment 311 are connected to two second rod segments 312. The two ends of the first rod segment 311 are respectively provided with two first rod bodies 3111 extending in a first direction, and the second rod body 3113 also extends in the first direction. The first bent rod 3112 extends in the second direction and is connected to the first rod body 3111 and the second rod body 3113 respectively. In this case, the two first bent rods 3112 can be connected to the two ends of one second rod body 3113 respectively, or the two first bent rods 3112 can be connected to the two second rod bodies 3113.

[0057] The arrangement of the first rod 3111, the first bent rod 3112, and the second rod 3113 ensures that the first rod segment 311 has at least one bent structure, and that the axes of the first rod 3111, the first bent rod 3112, and the second rod 3113 are not collinear. This prevents the first rod segment 311 from rotating relative to the outer cylinder 10 after it is fixedly connected to the outer cylinder 10. In some embodiments, the fixing buckle 35 is connected to at least two of the first rod 3111, the first bent rod 3112, and the second rod 3113 to fix the first rod segment 311 to the outer cylinder 10 and prevent the first rod segment 311 from rotating relative to the outer cylinder 10 or from rotating on its own.

[0058] According to some embodiments of this application, as shown in FIG4, the first rod segment 311 further includes a second bent rod 3114 and a third rod body 3115. The second bent rod 3114 extends in a second direction, and one end of the second bent rod 3114 is connected to the other end of the second rod body 3113. The third rod body 3115 is arranged parallel to the second rod body 3113 and is connected to the other end of the second bent rod 3114. In some embodiments, two first rods 3111 extend in a first direction and are respectively connected to two first bent rods 3112, two first bent rods 3112 extend in a second direction and are respectively connected to two second rods 3113, two second rods 3113 extend in a first direction and are respectively connected to two second bent rods 3114, and two second bent rods 3114 extend in a second direction and are connected to both ends of the same third rod 3115, so as to form a first rod segment 311 with multiple bent portions, so that the first rod segment 311 will not rotate relative to the outer cylinder 10 or rotate on its own after engaging with the second rod segment 312 and the fixing buckle 35, thus ensuring the damping and buffering capacity of the buffer rod 30 for the damping structure 20 and the fixed stability of the buffer rod 30.

[0059] In some embodiments, as shown in FIG4, the lengths of the two first bending rods 3112 extending in the second direction may differ to avoid other structural components on the outer cylinder 10. Similarly, the lengths of the two first rods 3111, the two second rods 3113, and the two second bending rods 3114 may be the same or different, and can be designed according to actual needs.

[0060] According to some embodiments of this application, as shown in FIG3, multiple fixing buckles 35 are constructed. These multiple fixing buckles 35 engage with at least two of the first rod 3111, the first bent rod 3112, the second rod 3113, the second bent rod 3114, and the third rod 3115. In this case, the multiple fixing buckles 35 are staggered along the extension direction of the first rod segment 311, which can restrict the rotation of the first rod segment 311, preventing it from rotating relative to the outer cylinder 10, thus improving the connection stability between the first rod segment 311 and the outer cylinder 10. It can also restrict the first rod segment 311 from rotating along its own axial direction. In the embodiment shown in FIG2, the fixing buckles 35 engage with the second rod 3113 and the third rod 3115 respectively. In this case, the multiple fixing buckles 35 face the same direction, facilitating the engagement and connection between the fixing buckles 35 and the outer cylinder 10.

[0061] Here, the lengths of the first rod 3111, the first bent rod 3112, the second rod 3113, the second bent rod 3114, and the third rod 3115 can be the same or different. By designing different rod lengths and coordinating with the position design of the fixing buckle 35, the connection stiffness between the first rod segment 311 and the outer cylinder 10 can be adjusted.

[0062] According to some embodiments of this application, as shown in FIG13, the vibration damping structure 20 further includes a sleeve 22, which is sleeved on the outer periphery of the support rod 21. The sleeve 22 is provided with a connecting portion 221. The sleeve 22 is adapted to rub against the outer periphery of the support rod 21 to attenuate the vibration transmitted between the support rod 21 and the sleeve 22. In some embodiments, a mounting cavity is formed inside the housing of the garment processing device 1. One end of the support rod 21 is hinged to the outer cylinder 10, and the other end of the support rod 21 is hinged to the inner wall of the mounting cavity. When the outer cylinder 10 vibrates, the support rod 21 rotates slightly about the end hinged to the inner wall of the mounting cavity. The buffer rod 30 connects the two support rods 21 and connects to the outer cylinder 10.

[0063] In the embodiment shown in Figure 1, when the garment processing equipment 1 is not in operation, the two support rods 21 in a set of vibration damping components are inclined towards each other. At this time, the support rods 21 have a good supporting effect on the outer cylinder 10. When the support rods 21 rotate slightly, since the buffer rod 30 connects the two support rods 21, the two support rods 21 may rotate towards each other, and the distance between the two support rods 21 is closer. A sleeve 22 that can move relative to the support rods 21 is provided, and a connecting part 221 connected to the vibration damping rod is designed on the sleeve 22 so that the sleeve 22 can move while the support rods 21 rotate, thereby driving the buffer rod 30 to slide down. Since the connecting part 221 of the sleeve 22 is relatively fixedly connected to the buffer part 320 of the buffer rod 30, that is, the sleeve 22 and the buffer rod 30 will not rotate relative to each other. So when the support rods 21 rotate, the sleeve 22 will inhibit the support rods 21 from continuing to rotate, thereby reducing the rotation amplitude of the support rods 21, thereby reducing the vibration amplitude of the vibration damping structure 20 and reducing the noise transmitted to the outside of the garment processing equipment 1.

[0064] When the sleeve 22 moves relative to the support rod 21, the sleeve 22 will rub against the outer periphery of the support rod 21, which can also attenuate the vibration transmitted between the support rod 21 and the sleeve 22, thereby improving the vibration reduction effect of the vibration reduction structure 20.

[0065] According to some embodiments of this application, a bushing is further provided between the sleeve 22 and the support rod 21. The bushing is adapted to rub against the outer periphery of the sleeve 22 and / or the support rod 21 to attenuate the vibration transmitted between the support rod 21 and the sleeve 22. When the sleeve 22 moves relative to the support rod 21, the sleeve 22 will rub against the outer periphery of the support rod 21, and the bushing will rub against the outer periphery of the sleeve 22 and / or the support rod 21 at the same time, which can further attenuate the vibration transmitted between the support rod 21 and the sleeve 22 and improve the vibration reduction effect.

[0066] According to some embodiments of this application, as shown in Figures 10-14, the garment processing device 1 further includes an anti-rotation structure. The anti-rotation structure is disposed on the buffer rod 30 and is adapted to cooperate with at least one of the outer cylinder 10 and the vibration damping structure 20 to limit the rotation of the buffer rod 30 relative to the outer cylinder 10 and / or limit the rotation of the buffer rod 30 along its own axial direction. Here, to ensure the connection stability between the buffer rod 30 and the vibration damping structure 20, an anti-rotation structure is designed. The anti-rotation structure connects the buffer rod 30 to the outer cylinder 10 and / or the vibration damping structure 20, and is adapted to limit the rotation of the buffer rod 30 relative to the outer cylinder 10 and / or limit the rotation of the buffer rod 30 along its own axial direction, so that after the buffer rod 30 cooperates with the vibration damping structure 20, it will not rotate relative to the outer cylinder 10 or rotate on its own axis, ensuring the vibration damping and buffering capacity of the buffer rod 30 on the vibration damping structure 20, and the fixed stability of the buffer rod 30.

[0067] According to the clothing processing device 1 of this application, a buffer rod 30 is provided to connect at least two vibration damping structures 20. The buffer rod 30 can balance the vibration between the at least two vibration damping structures 20 connected to it, reduce the eccentricity of the outer cylinder 10, and thus reduce vibration noise. At the same time, an anti-rotation structure is also provided to connect the buffer rod 30 to the outer cylinder 10 and / or the vibration damping structure 20, so as to limit the rotation of the buffer rod 30 relative to the outer cylinder 10 and / or limit the rotation of the buffer rod 30 along its own axis, ensuring the vibration damping and buffering capacity of the buffer rod 30 on the vibration damping structure 20, and the fixed stability of the buffer rod 30, further reducing vibration noise and improving the user experience.

[0068] According to some embodiments of this application, as shown in FIG12, the anti-rotation structure includes an anti-rotation block 40, which is fixedly disposed on the outer peripheral surface of the buffer rod 30 and is adapted to be fixedly connected to the outer surface of the outer cylinder 10. Here, the anti-rotation block 40 is fixedly connected to both the buffer rod 30 and the outer cylinder 10 to fix the buffer rod 30 to the outer surface of the outer cylinder 10. The anti-rotation block 40 fixes the buffer rod 30 to the outer cylinder 10 to restrict the buffer rod 30 from rotating relative to the outer cylinder 10 or from rotating on its own.

[0069] In some embodiments, when there is a relative rotational tendency between the buffer rod 30 and the outer cylinder 10, the outer surface of the anti-rotation block 40 can be fixedly connected to the outer surface of the outer cylinder 10 to limit the buffer rod 30 from rotating relative to the outer cylinder 10 or from rotating on its own. The outer surface of the anti-rotation block 40 can also abut against the outer surface of the outer cylinder 10 to limit the buffer rod 30 from rotating relative to the outer cylinder 10.

[0070] According to some embodiments of this application, as shown in Figures 9-12, the garment processing device 1 further includes a fixing buckle 35, which is fixedly connected to the outer cylinder 10. The fixing buckle 35 forms a groove 3531a suitable for receiving the anti-rotation block 40. The groove 3531a cooperates with the anti-rotation block 40 to restrict the rotation of the buffer rod 30 relative to the outer cylinder 10. In the embodiment shown in Figure 12, the fixing buckle 35 connects the anti-rotation block 40 to the outer cylinder 10, and the anti-rotation block 40 is snapped into the groove 3531a of the fixing buckle 35. Since the anti-rotation block 40 is fixedly mounted on the buffer rod 30, when the fixing buckle 35 is connected to the outer cylinder 10, the anti-rotation block 40 cannot rotate relative to the fixing buckle 35, that is, the buffer rod 30 cannot rotate relative to the fixing buckle 35. By setting the fixing buckle 35, the buffer rod 30 is fixed to the outer cylinder 10, restricting the rotation of the buffer rod 30 relative to the outer cylinder 10, and at the same time restricting the rotation of the buffer rod 30 relative to the outer cylinder 10.

[0071] According to some embodiments of this application, as shown in FIG12, the shape of the groove 3531a is adapted to the shape of the anti-rotation block 40, and the cross-section of the anti-rotation block 40 is non-circular in the extending direction of the buffer rod 30, so as to restrict the buffer rod 30 from rotating along its own axial direction. Here, when the anti-rotation block 40 and the fixing buckle 35 have a tendency to rotate relative to each other, the outer surface of the anti-rotation block 40 can abut against the inner wall surface of the groove 3531a to restrict the anti-rotation block 40 from rotating relative to the fixing buckle 35, thereby restricting the buffer rod 30 from rotating along its own axial direction.

[0072] In some embodiments, non-circular shapes can refer to polygons such as triangles, quadrilaterals (as shown in Figure 12), pentagons, etc., or ellipses or other irregular shapes. The shape of the anti-rotation block 40 is sufficient to abut against the inner wall of the groove 3531a when the anti-rotation block 40 and the fixing buckle 35 have a relative rotation tendency, so as to limit the relative rotation between the anti-rotation block 40 and the fixing buckle 35 and ensure the connection stability between the buffer rod 30 and the outer cylinder 10.

[0073] Here, the cross-sectional shape of the buffer rod 30 in the upward direction is not limited and can be circular, elliptical, polygonal, or other shapes.

[0074] According to some embodiments of this application, as shown in FIG9, the fixing buckle 35 includes a first plate portion 351, a second plate portion 352 and a third plate portion 353. The first plate portion 351 and the second plate portion 352 are spaced apart in the extending direction, and one end of the first plate portion 351 is directly opposite to one end of the second plate portion 352. The first plate portion 351 and the second plate portion 352 are adapted to be fixedly connected to the outer cylinder 10. One end of the third plate portion 353 is connected to one end of the first plate portion 351 and the other end of the third plate portion 353 is connected to one end of the second plate portion 352. At least a portion of the third plate portion 353 protrudes toward one side in the thickness direction to form a protrusion 3531. The protrusion 3531 forms a groove 3531a on the other side of the third plate portion 353 in the thickness direction.

[0075] In some embodiments, the first plate portion 351 and the second plate portion 352 are connected to the outer cylinder 10 by bolts.

[0076] According to some embodiments of this application, the garment processing device 1 further includes a fourth buffer (not shown), which is disposed between the groove 3531a and the anti-rotation block 40, and is adapted to attenuate the vibration between the fixing buckle 35 and the anti-rotation block 40. The vibrational energy between the fixing buckle 35 and the anti-rotation block 40 is transmitted to the fourth buffer, causing the fourth buffer to attenuate the force transmitted to the buffer rod 30, thereby ensuring the connection stability of the fixing buckle 35 and the anti-rotation block 40, reducing the probability of vibration caused by relative movement of the fixing buckle 35 and the anti-rotation block 40, and thus reducing the noise generated by the connection between the fixing buckle 35 and the anti-rotation block 40.

[0077] In some embodiments, the fourth buffer can be sleeved on the outer periphery of the anti-rotation block 40. When the outer cylinder 10 vibrates, the anti-rotation block 40 may move relative to the fixed buckle 35, causing vibration between the fixed buckle 35 and the anti-rotation block 40. At this time, the fourth buffer can buffer the vibration between the fixed buckle 35 and the anti-rotation block 40, thereby attenuating the vibration between the outer cylinder 10 and the buffer rod 30.

[0078] In the above embodiments, the fourth buffer can be set at the position where the buffer rod 30 is subjected to greater force, or it can be set at the connection between the two structures to reduce the stiffness of the fit between the two structures. The force between the two structures can be transmitted to the fourth buffer, and the compression of the fourth buffer will also increase, so that the energy absorption and vibration reduction effect of the fourth buffer is better.

[0079] In some embodiments, the performance of the fourth buffer needs to meet the requirement that, when the buffer rod 30 is subjected to a constant vibration frequency, the damping factor of the fourth buffer is ≥0.8.

[0080] In summary, the garment processing device 1 according to this application is equipped with a buffer rod 30 to connect at least two vibration damping structures 20, which can balance the vibration between the at least two vibration damping structures 20 connected thereto, reduce the eccentricity of the outer cylinder 10, reduce the vibration noise of the garment processing device 1, and improve the user experience.
