Description

Technical Field

[0001] This application relates to the field of clothing processing equipment technology, and in particular to a vibration damping device and clothing processing equipment. Background Technology

[0002] In the field of clothing processing equipment, top-loading washing machines and front-loading washing machines are common types. Taking a top-loading washing machine as an example, it typically includes a cabinet and a drum assembly housed within the cabinet. The drum assembly is axially vertical and includes an outer drum and an inner drum rotatably disposed within the outer drum. The outer drum is suspended inside the cabinet by several rods. During the washing and spin-drying processes, the inner drum rotates relative to the outer drum, causing the clothes to interact with the washing water, achieving the effect of washing or dehydrating the clothes. At the same time, the rods can buffer vertical vibrations.

[0003] However, due to the uneven load on the cylinder assembly, under the influence of eccentric force, the cylinder assembly not only vibrates in the vertical direction, but also swings in the horizontal direction, which makes the cylinder assembly prone to impacting the housing and causing damage. Summary of the Invention

[0004] This application provides a vibration damping device and a garment processing equipment, which can reduce the lateral vibration displacement of the tube assembly and prevent the tube assembly from impacting the housing.

[0005] To achieve the above objectives, a first aspect of this application provides a vibration damping device applied to a garment processing equipment. The garment processing equipment includes a housing, a cylindrical assembly disposed within the housing, and a suspension rod connecting the housing and the cylindrical assembly. The vibration damping device is disposed between the housing and the cylindrical assembly. The vibration damping device comprises:

[0006] A first moving component, one end of which is connected to the cylindrical assembly;

[0007] A second moving component, one end of which is rotatably connected to the other end of the first moving component, and the other end of which is connected to the housing or the lifting rod; and

[0008] A friction element is disposed at the connection between the first moving element and the second moving element, and is used to provide damping force when the first moving element and the second moving element rotate relative to each other;

[0009] Wherein, the first moving member is telescopically oriented along a first direction; and / or, the second moving member is telescopically oriented along a second direction;

[0010] The first direction is the direction of the line connecting the two ends of the first moving part, and the second direction is the direction of the line connecting the two ends of the second moving part.

[0011] In some embodiments, the second moving member includes:

[0018] In some embodiments, the buffer groove is provided with an elastic element, one end of which is connected to the groove wall of the buffer groove, and the other end is connected to the second connecting part.

[0019] In some embodiments, the vibration damping device further includes a pivot;

[0020] The first moving component includes:

[0021] A first connecting portion is connected to the cylindrical assembly; and

[0022] A first main body portion is connected to the first connecting portion and hinged to the second main body portion via the pivot;

[0023] The first main body portion and / or the second main body portion are slidably connected to the pivot along the axial direction of the pivot.

[0024] In some embodiments, the first main body and the second main body are nested and both are radially configured to form an installation space, and the friction member is disposed within the installation space;

[0025] The friction element and the first main body are integrally injection molded, or the friction element and the second main body are integrally injection molded.

[0026] A second aspect of this application provides a garment processing device, comprising:

[0027] Box;

[0028] The cylindrical assembly is disposed within the housing;

[0029] A boom connecting the housing and the cylindrical assembly; and

[0030] In the vibration damping device described above, the first moving component is connected to the cylinder assembly, and the second moving component is connected to the housing or the boom.

[0031] In some embodiments, one end of the boom is connected to the housing, and the other end is elastically connected to the cylinder assembly, wherein the second moving member is sleeved on the outer periphery of the boom.

[0032] In some embodiments, the second moving member has a sleeve portion for engaging the boom, the sleeve portion having a disassembly opening at both ends spaced apart along the extension direction of the boom.

[0033] In some embodiments, the connection portion between the first moving member and the cylinder assembly is made of a wear-resistant material, and / or the connection portion between the second moving member and the boom is made of a wear-resistant material.

[0034] In some embodiments, the garment processing device further includes:

[0035] Mounting base, connected to the outer peripheral wall of the cylindrical assembly; and

[0036] A quick-release mechanism is connected to the first moving part and is used to fix the first moving part on the mounting base.

[0037] In some embodiments, the first moving member has a first connecting hole, and the mounting base has a second connecting hole; wherein, the quick-release mechanism includes:

[0038] A fastener, passing through the first connecting hole and the second connecting hole, with a portion of the fastener exposed outside the second connecting hole; and

[0039] The limiting member is detachably connected to the mounting base and abuts against the portion of the fixing member exposed outside the second connecting hole.

[0040] In some embodiments, the mounting base is provided with a limiting groove, the bottom wall of the limiting groove has a second connecting hole, the fixing member includes a first fixing part and a second fixing part connected together, the first fixing part and the second fixing part are arranged at an angle, the first fixing part passes through the first connecting hole and the second connecting hole, and the second fixing part is disposed in the limiting groove;

[0041] The limiting member is configured as a screw, the head of which covers part of the opening of the limiting groove to limit the second fixing part within the limiting groove.

[0042] In some embodiments, the vibration damping device includes a plurality of devices, which are spaced apart on the outer peripheral wall of the cylinder assembly;

[0043] In one of the two adjacent vibration damping devices, the first moving part of one vibration damping device is connected to the second moving part of the other vibration damping device.

[0044] In the vibration damping device provided in this application embodiment, the first moving part is connected to the cylinder assembly, one end of the second moving part is rotatably connected to the first moving part, and the other end is connected to the housing. The friction element is disposed at the connection between the first moving part and the second moving part, and provides damping force when the first moving part and the second moving part rotate relative to each other. Thus, when the clothing processing equipment is running, the cylinder assembly swings laterally, causing the first moving part and the second moving part to rotate relative to each other. The friction element provides damping force to prevent the relative rotation of the first moving part and the second moving part, thereby reducing the lateral vibration displacement of the cylinder assembly and avoiding collision between the cylinder assembly and the housing.

[0045] Simultaneously, the first moving member is extendable and retractable along a first direction; and / or, the second moving member is extendable and retractable along a second direction. Thus, while the first and second moving members rotate relative to each other, they can also absorb the energy generated by the cylinder assembly during lateral vibration through their own telescopic movement. This allows the first and second moving members to adaptively adjust during lateral vibration, enabling the vibration damping device to better adapt to lateral vibrations of different frequencies and amplitudes.

[0065] This application provides a garment processing device and its vibration damping device, which aims to solve the problem caused by lateral swaying due to uneven load on the drum assembly during operation of existing garment processing equipment, such as damage to the equipment caused by the drum assembly hitting the housing, thereby improving the stability of the garment processing equipment operation.

[0066] Specifically, please refer to Figures 1 to 6 , Figure 1 A top-view structural diagram of the garment processing device provided in an embodiment of this application; Figure 2 A schematic diagram of the structure of the garment processing equipment provided in the embodiments of this application (the housing is omitted); Figure 3 Another structural schematic diagram of the clothing processing device provided in the embodiments of this application (the housing is omitted); Figure 4 for Figure 3 Enlarged view of point A in the middle; Figure 5 This is a schematic diagram of the vibration damping device provided in the embodiments of this application; Figure 6 for Figure 5 A cross-sectional view along the BB direction.

[0067] The garment processing device of this embodiment includes a housing 200, a drum assembly 300, a hanging rod 4, and a vibration damping device 100. This garment processing device can be a washing machine, such as a top-loading washing machine or a front-loading washing machine. For ease of description, the embodiments of this application will be described using a top-loading washing machine as an example.

[0068] The cabinet 200 is generally made of sheet metal by bending. The cabinet 200 includes an internal space with an open end and a worktable covering the open end. This internal space can house other components of the washing machine, such as circuitry, air ducts, a drive mechanism, and drainage components. A detergent dispenser can be located at the front end of the worktable. The cabinet 200 can be a hollow cuboid or a hollow cylinder. The inner periphery of the cabinet 200 generally has four corners, each with a corner plate 201.

[0069] The drum assembly 300 is disposed within the housing 200, and a mounting block 301 is provided at the bottom of the drum assembly 300. For a top-loading washing machine, the axial direction of the drum assembly 300 is the same as the height direction of the housing 200. For a front-loading washing machine, the axial direction of the drum assembly 300 intersects with the height direction of the housing 200. Taking a top-loading washing machine as an example, the drum assembly 300 includes an outer drum and an inner drum rotatably disposed within the outer drum. The inner drum is hollow to form a washing chamber. A through hole is provided on the peripheral wall of the inner drum, through which washing water can be discharged from the inner drum to the outer drum. A wastewater outlet is provided at the bottom of the outer drum, and washing water is discharged from the machine body through a drain assembly connected to the wastewater outlet. A loading and unloading port communicating with the washing chamber is provided at the top of the drum assembly 300, through which clothes are placed into the washing chamber for washing. A door is provided correspondingly in the housing 200 to close the loading and unloading port of the drum assembly 300 when washing clothes, so that the washing chamber is a sealed space when washing clothes. Taking a top-loading washing machine as an example, a top-loading washing machine is a type of washing machine in which a motor drives the pulsator to rotate, and the clothes tumble up and down with the water. Driven by the pulsator, the water in the drum assembly 300 of the washing machine forms an alternating left-hand and right-hand vortex, which drives the clothes to rotate and tumble, thereby achieving the washing and dehydration of the clothes.

[0070] In this embodiment, the boom 4 connects the housing 200 and the cylinder assembly 300. For example, as shown... Figure 2As shown, one end of the hanger 4 is connected to the housing 200, and the other end is elastically connected to the cylinder assembly 300. The hanger 4 can be made of high-strength metal, such as stainless steel or aluminum alloy. Exemplarily, the outer wall of the cylinder assembly 300 is also provided with a vibration-damping sleeve 5. The hangers 4 are generally vertically distributed, with the upper end of the hanger 4 connected to the corresponding corner plate 201 of the housing 200 via a positioning element, and the lower end of the hanger 4 connected to the vibration-damping sleeve 5. The vibration-damping sleeve 5 is fixedly connected to the mounting block 301 at the bottom of the cylinder assembly 300. The vibration-damping sleeve 5 contains a spring assembly 51 and a spring seat 52 for fixing the spring assembly 51. Thus, the hanger 4 can be used to buffer the vibration of the cylinder assembly 300 along the height direction.

[0071] In one embodiment, the vibration damping device 100 is provided on only two of the four corner plates 201 of the housing 200 located on the diagonal. In another example, the vibration damping device 100 is provided on each of the four corner plates 201 of the housing 200.

[0072] In existing technology, garment processing equipment typically uses a hanging rod 4 and a vibration damping sleeve 5 to reduce the vertical displacement of the drum assembly 300 during operation. However, it lacks a mechanism to manage the horizontal displacement of the drum assembly 300. In actual operation, especially during the dehydration stage, the drum assembly 300 may experience eccentric force due to uneven load, causing it to swing significantly in the horizontal direction. If this horizontal displacement is not effectively controlled, it can easily cause the drum assembly 300 to collide with the housing 200, leading to problems such as increased noise and vibration, or even component damage.

[0073] Therefore, this application provides a vibration damping device 100 that can control the horizontal displacement of the cylinder assembly 300 during operation.

[0074] Specifically, such as Figures 4 to 6 As shown, the vibration damping device 100 includes a first moving part 1, a second moving part 2, and a friction part 8.

[0075] One end of the first moving part 1 is connected to the cylinder assembly 300, and the connection method can be bolt connection, welding, etc. The first moving part 1 is telescopically oriented along a first direction. In this embodiment, the first direction is the direction of the line connecting the two ends of the first moving part 1. For example, if the connection point between the first moving part 1 and the cylinder assembly 300 is point A, and the connection point between the first moving part 1 and the second moving part 2 is point B, then the first direction is the direction of the line connecting points A and B.

[0076] In one embodiment, the first moving member 1 is generally rod-shaped, with its length as the first direction, and is extendable along its length. The extendable nature of the first moving member 1 can be achieved using a telescopic rod structure. For example, the first moving member 1 consists of an inner rod and an outer sleeve, with the inner rod freely extending and retracting within the outer sleeve. The inner rod is connected to the cylinder assembly 300, and the outer sleeve is rotatably connected to the second moving member 2. When the cylinder assembly 300 experiences lateral vibration, the inner rod extends and retracts within the outer sleeve in response to the vibration. Alternatively, the first moving member 1 can also employ a slider-rail structure. In this embodiment, the extendable first moving member 1 allows it to absorb some vibration energy during the lateral swing of the cylinder assembly 300, reducing the vibration amplitude transmitted to the second moving member 2 and the housing 200. Simultaneously, the extendable first moving member 1 can adaptively adjust to different amplitudes of lateral vibration in the cylinder assembly 300, improving the adaptability of the vibration damping device 100 to different operating conditions.

[0077] One end of the second moving part 2 is rotatably connected to the other end of the first moving part 1. In one configuration, the first moving part 1 and the second moving part 2 are stacked, and the second moving part 2 and the first moving part 1 can be connected by a pin. Through holes of corresponding diameters are respectively opened at the connection points of the first moving part 1 and the second moving part 2, and the pin is passed through the two through holes, allowing the second moving part 2 to rotate freely relative to the first moving part 1 around the pin.

[0078] In another configuration, such as Figure 8 and Figure 9 As shown, the first moving part 1 and the second moving part 2 are partially nested. The vibration damping device 100 also includes an elastic hook 13. The second moving part 2 has a mounting hole adapted to the elastic hook 13. One end of the elastic hook 13 is connected to the first moving part 1, and the other end passes through the mounting hole of the second moving part 2 and latches onto the upper surface of the second moving part 2. The elastic hook 13 is a structure with elasticity and the ability to deform. During installation, the elastic hook 13 is inserted into the mounting hole from bottom to top. During insertion, the elastic hook 13 undergoes elastic deformation. After extending out of the mounting hole, the elastic hook 13 recovers its deformation and engages with the end face of the mounting hole, thereby connecting the first moving part 1 and the second moving part 2 together, reducing the probability of the first moving part 1 dislodging from the second moving part 2, and increasing the installation stability of the vibration damping device 100.

[0079] In another configuration, such as Figure 4As shown, the vibration damping device 100 also includes a pivot 7, which is a cylindrical shaft. The first moving member 1 and the second moving member 2 are hinged together via the pivot 7. The description of the rotational connection method of the first moving member 1 and the second moving member 2 in this application is only an example. Various rotational connection methods can be adopted according to actual needs, as long as the relative rotation between the two can be achieved, thereby dispersing and buffering lateral vibration. For example, the rotational connection method can be a spherical joint, a flexible connection, a universal joint connection, or any other effective connection method that can achieve the expected function.

[0080] The other end of the second moving component 2 is connected to the housing 200 or the lifting rod 4. In one embodiment, the other end of the second moving component 2 is connected to the housing 200. Specifically, the housing 200 includes a housing body and a connecting rod disposed on the housing body. The second moving component is connected to the connecting rod, and the connection method can be sleeve, welding, bolt connection, etc.

[0081] In another embodiment, the other end of the second moving part 2 is connected to the rod 4. The connection method can be slidably sleeved on the rod 4, welded to the rod 4, bolted to the rod 4, etc.

[0082] The second moving member 2 is extendable and retractable along the second direction. In this embodiment, the second direction is the direction of the line connecting the two ends of the second moving member 2. For example, if the connection between the second moving member 2 and the first moving member 1 is point B, and the connection between the second moving member 2 and the housing 200 or the lifting rod 4 is point C, then the second direction is the direction of the line connecting points B and C.

[0083] In one embodiment, the second moving member 2 is generally rod-shaped, with the second direction being the length direction of the second moving member 2, and the second moving member 2 is extendable and retractable along the length direction. The extension and retraction of the second moving member 2 is similar to that of the first moving member 1, for example, by using a sleeve-type telescopic structure or a sliding rail block structure. When the cylinder assembly 300 vibrates laterally, the second moving member 2 can not only buffer the vibration through relative rotation with the first moving member 1, but also further absorb vibration energy through its own extension and retraction in the direction toward the housing 200. This enables the vibration damping device 100 to absorb energy and buffer vibration from multiple dimensions when dealing with complex lateral vibrations, effectively reducing the impact of the lateral vibration of the cylinder assembly 300 on the housing 200.

[0084] Friction element 8 is located at the connection between the first moving element 1 and the second moving element 2. Friction element 8 can be made of a material with a high coefficient of friction, such as rubber or friction pads. When the first moving element 1 and the second moving element 2 rotate relative to each other, friction element 8 provides damping force.

[0085] In one configuration, the friction element 8 can be in the form of a friction plate, sandwiched between the opposing end faces of the first moving element 1 and the second moving element 2. In another configuration, the friction element 8 can be in the form of a friction sleeve, embedded between the peripheral walls of the first moving element 1 and the second moving element 2.

[0086] During operation of the garment processing equipment, the drum assembly 300 of the pulsator washing machine oscillates laterally due to factors such as uneven placement of clothes. At this time, the first moving part 1 connected to the drum assembly 300 oscillates along with the drum assembly 300, causing the second moving part 2, which is rotatably connected to the first moving part 1, to rotate relative to it. During the relative rotation of the first moving part 1 and the second moving part 2, the friction element 8 located at their connection point generates damping force, dissipating vibration energy and reducing the lateral vibration displacement of the drum assembly 300, effectively preventing the drum assembly 300 from colliding with the casing 200. Simultaneously, the first moving part 1 is extendable along a first direction; and / or the second moving part 2 is extendable along a second direction. When the drum assembly 300 vibrates laterally, the first moving part 1 and the second moving part 2, in addition to relative rotation, can further absorb vibration energy through their own extension and retraction. The first moving part 1 and the second moving part 2 can adaptively adjust according to lateral vibrations of different frequencies and amplitudes, enabling the vibration damping device 100 to better adapt to complex operating conditions, improving the vibration damping performance of the garment processing equipment, and thus ensuring stable operation of the equipment.

[0087] In some embodiments, the first moving member 1 includes a first main body portion 11, and the second moving member 2 includes a second main body portion 21. The first main body portion 11 and the second main body portion 21 may be arranged in a ring shape, and the second main body portion 21 is hinged to the first main body portion 11 via a pivot 7. The two are mainly connected by the pivot 7 and rotate in the circumferential direction, that is, the pivot 7 passes through the first main body portion 11 and the second main body portion 21, and the first main body portion 11 and / or the second main body portion 21 are slidably connected along the axial direction of the pivot 7. Understandably, the pivot 7 is arranged approximately parallel to the axial direction of the cylinder assembly 300, and plugs are provided at both ends of the pivot 7 to prevent the first main body portion 11 and the second main body portion 21 from disengaging from the pivot 7 when sliding relative to the pivot 7. To reduce the impact between the first main body portion 11 and the second main body portion 21 and the plugs during sliding, elastic gaskets can be provided on the side of the two plugs facing the first moving member 1 and the second moving member 2. The elastic pads effectively buffer impact forces, reduce wear between components, and lower operating noise, further improving the reliability and service life of the vibration damping device 100.

[0088] In some embodiments, the first main body portion 11 and the second main body portion 21 are nested together and both are radially configured to form an installation space, and the friction member 8 is disposed within the installation space.

[0089] Please continue reading. Figure 6The friction element 8 is integrally injection molded with the first main body 11, or the friction element 8 is integrally injection molded with the second main body 21. Integral injection molding reduces assembly steps and the number of parts, thereby reducing production costs. The friction element 8 does not need to be manufactured and assembled separately, saving materials. Furthermore, integrally injection molded parts generally have better structural strength and stability because they have no seams or connection points and can better withstand mechanical stress.

[0090] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the second moving member 2 further includes a second connecting portion 22. The second connecting portion 22 extends along a second direction, and one end of the second connecting portion 22 is slidably connected to the second main body portion 21, while the other end of the second connecting portion 22 is connected to the housing 200 or the lifting rod 4.

[0091] Specifically, the second main body 21 includes a second annular sub-part 211 and a sleeve sub-part 212. The second annular sub-part 211 is rotatably connected to the first main body 11. For example, the first main body 11 and the second annular sub-part 211 are hinged by a pivot 7.

[0092] The sleeve portion 212 is connected to the outer periphery of the second annular portion 211 and has a buffer groove 212a extending in the second direction. The buffer groove 212a allows the second connecting portion 22 to extend into, thereby enabling a slidable connection between the second main body portion 21 and the second connecting portion 22. Specifically, at least a portion of the second connecting portion 22 passes through this buffer groove 212a. When the cylinder assembly 300 experiences lateral vibration, the second main body portion 21 is displaced under the action of the first moving member 1. Since the second connecting portion 22 passes through the buffer groove 212a, it can slide relative to the second main body portion 21 within the range defined by the buffer groove 212a. For example, when the cylinder assembly 300 swings to one side, the second main body portion 21 also moves to that side under the action of the first moving member 1. At this time, the second connecting portion 22 slides within the buffer groove 212a. This sliding engagement can further absorb and disperse the energy generated by the lateral vibration of the cylinder assembly 300, effectively reducing the impact of vibration on the equipment.

[0093] Furthermore, such as Figure 6As shown, an elastic element is provided inside the buffer groove 212a. One end of the elastic element is connected to the wall of the buffer groove 212a, and the other end is connected to the second connecting part 22. The elastic element can be made of a material with good elastic properties, such as a rubber spring or a coil spring. When the cylinder assembly 300 vibrates laterally, causing the second connecting part 22 to slide relative to the second main body 21 within the buffer groove 212a, the elastic element will deform accordingly. For example, when the second main body 21 slides to one side, the elastic element will be compressed or stretched. During this process, the elastic deformation of the elastic element absorbs part of the energy generated by the lateral vibration of the cylinder assembly 300. When the vibration direction changes, the elastic element will release the stored energy, playing a buffering and restoring role on the movement of the second main body 21. In other words, the setting of the elastic element provides further protection for the lateral vibration of the cylinder assembly 300, enabling the second moving part 2 to absorb energy and buffer vibration from multiple aspects, thereby improving the vibration reduction effect of the vibration damping device 100, ensuring the stability of the clothing processing equipment operation, and extending the service life of the equipment. It is understandable that the first moving part 1 may also be provided with features such as buffer groove 212a and elastic element, which will not be repeated here.

[0094] In some embodiments, the first moving member 1 further includes a first connecting portion 12 connected to the first main body 11. The first connecting portion 12 has a length direction, and one end of its length away from the first main body 11 is connected to the cylinder assembly 300. A second connecting portion 22 has a length direction, and the end of the second connecting portion 22 away from the second main body 21 has a first through hole 22a. The second connecting portion 22 is sleeved on the outer periphery of the hanger 4 through the first through hole 22a, so that the second connecting portion 22 is connected to the hanger 4, ensuring that the second moving member 2 maintains a stable connection state during vibration. Furthermore, the second connecting portion 22 can slide along the axial direction of the hanger 4, effectively absorbing and dispersing the vibration energy generated by the cylinder assembly 300 during operation. This design can reduce the amplitude of vibration transmitted to the housing 200 or other components, thereby improving the vibration damping performance of the vibration damping device 100.

[0095] At least a portion of the first connecting part 12 and / or the second connecting part 22 is made of wear-resistant material. This wear-resistant material can significantly reduce wear on the first connecting part 12 and / or the second connecting part 22 during long-term operation, especially under conditions of high vibration, high impact, or frequent friction. For example, the first connecting part 12 and / or the second connecting part 22 may be made of high-hardness ceramic material or alloyed wear-resistant steel, which can effectively resist the erosion and wear of particulate matter, thereby extending the service life of the first connecting part 12 and / or the second connecting part 22.

[0096] like Figure 7As shown, in the case of repairing and replacing the boom 4, in order to facilitate the disassembly between the boom 4 and the second connecting part 22, in one embodiment, the second moving member 2 has a sleeve part 222 for sleeved with the boom 4. The sleeve part 222 is constructed with a disassembly opening 22b, and the two ends of the disassembly opening 22b are spaced apart along the extension direction of the boom 4.

[0097] Specifically, the second connecting portion 22 includes a connecting sub-portion 221 and a socket sub-portion 222. The socket sub-portion 222 has a first through hole 22a. The two ends of the socket sub-portion 222 are spaced apart along the extension direction of the lifting rod 4 to form a disassembly / removal opening 22b for the lifting rod 4. The first and second ends of the socket sub-portion 222 are vertically misaligned, similar to a spiral arrangement. When it is necessary to disassemble the lifting rod 4, the lifting rod 4 can be tilted significantly laterally, allowing it to be removed from the disassembly / removal opening 22b formed by the first and second ends of the socket sub-portion 222. This design, by forming the disassembly / removal opening 22b, allows the lifting rod 4 to be easily removed when needed, greatly simplifying the disassembly and installation process and improving maintenance efficiency.

[0098] like Figure 9 and Figure 10 As shown, in some embodiments, the garment processing equipment further includes a mounting base 400 and a quick-release mechanism 500. The mounting base 400 protrudes from the outer peripheral wall of the tube assembly 300. The quick-release mechanism 500 is connected to the first connecting portion 12 and is used to fix the first connecting portion 12 onto the mounting base 400. The mounting base 400 provides a stable support point for the first connecting portion 12. The position of the mounting base 400 lays the foundation for the lateral connection position of the first moving part 1 and the second moving part 2. The quick-release mechanism 500 can be a locating pin, a rotating nut, or a wedge block and a locking tongue. The design of the quick-release mechanism 500 allows the first connecting portion 12 to be quickly fixed onto the mounting base 400 and also to be quickly disassembled when needed. This design greatly improves the maintenance efficiency of the equipment and reduces disassembly and assembly time.

[0099] To improve the connection effect of the first connecting part 12, two mounting seats 400 can be provided. The two mounting seats 400 are spaced apart along the axial direction of the cylinder assembly 300 on the outer peripheral wall of the cylinder assembly 300. The two mounting seats 400 are located on the upper and lower sides of the first connecting part 12, respectively, thereby realizing bidirectional clamping of the first connecting part 12. This ensures that the first connecting part 12 is effectively confined between the two mounting seats 400, enhancing the stability and reliability of the connection.

[0100] Please continue reading. Figure 9Specifically, the first connecting part 12 has a first connecting hole, and the mounting base 400 has a second connecting hole; wherein, the quick-release mechanism 500 includes a fixing member 510 and a limiting member 520, the size and shape of the first connecting hole and the second connecting hole are adapted to the fixing member 510 so that the fixing member 510 passes through the first connecting hole and the second connecting hole, and a part of the fixing member 510 is exposed outside the second connecting hole; the limiting member 520 is detachably connected to the mounting base 400 and abuts against the part of the fixing member 510 exposed outside the second connecting hole. The function of the limiting member 520 is to prevent the fixing member 510 from falling out of the second connecting hole, thereby maintaining the fixation of the first connecting part 12 and the mounting base 400.

[0101] Understandably, when it is necessary to disassemble the first connecting part 12, the limiting member 520 is removed first, and then the fixing member 510 can be easily removed from the second connecting hole, thereby separating the first connecting part 12 from the mounting base 400.

[0102] In some embodiments, the mounting base 400 is provided with a limiting groove 400a, the bottom wall of the limiting groove 400a has a second connecting hole, and the fixing member 510 includes a first fixing part 511 and a second fixing part 512 connected together. The first fixing part 511 and the second fixing part 512 are arranged at an angle. The first fixing part 511 passes through the first connecting hole and the second connecting hole, and the second fixing part 512 is disposed in the limiting groove 400a. Since the second fixing part 512 and the first fixing part 511 are arranged at an angle, for example, ninety degrees, the first fixing part 511 passes through the second connecting hole in the vertical direction, and the first fixing part 511 abuts against the bottom wall of the limiting groove 400a and will not pass through the second connecting hole. Furthermore, the groove wall of the limiting groove 400a, which is disposed opposite to the limiting groove, can restrict the rotation of the second fixing part 512 in the circumferential direction. The limiting member 520 is configured as a screw, and the head of the screw covers part of the groove opening of the limiting groove 400a to limit the second fixing part 512 within the limiting groove 400a. That is, the limiting groove 400a can restrict the circumferential rotation of the fixing member 510, while the screw can restrict the movement of the fixing member 510 in the vertical direction.

[0103] Understandably, when it is necessary to disassemble the first connecting part 12, simply unscrew the screw to release the second fixing part 512, and then the fixing member 510 can be easily removed from the second connecting hole, thereby separating the first connecting part 12 from the mounting base 400.

[0104] To improve the vibration reduction effect of the garment processing equipment, in some embodiments, multiple vibration reduction devices 100 are provided, and the multiple vibration reduction devices 100 are distributed at intervals on the outer peripheral wall of the cylinder assembly 300.

[0105] Multiple vibration damping devices 100 are installed to provide vibration damping protection for the drum assembly 300 from multiple directions. Since the drum assembly 300 may sway laterally in different directions during operation, the multiple vibration damping devices 100 arranged around the drum assembly 300 can comprehensively address its lateral vibration. For example, when the drum assembly 300 of a pulsator washing machine experiences significant lateral swaying in one direction due to uneven clothing placement, the corresponding vibration damping device 100 can function to reduce the amount of vibration displacement. When the swaying direction changes, the vibration damping devices 100 in other locations can continue to buffer the vibration, ensuring that the vibration of the drum assembly 300 is reduced in all directions.

[0106] In some embodiments, two adjacent vibration damping devices 100 are connected in series. The first moving part 1 of one vibration damping device 100 is connected to the second moving part 2 of the other vibration damping device 100. Thus, compared to the traditional mode where each vibration damping device 100 operates independently, the adjacent vibration damping devices 100 in this embodiment constitute an integrated vibration damping system. Specifically, the first moving part 1 and the second moving part 2 of adjacent vibration damping devices 100 are connected in series via a connector. The connector can be a metal rod, with one end connected to the first moving part 1 of one vibration damping device 100 and the other end connected to the second moving part 2 of the adjacent vibration damping device 100. For example, when a pulsator washing machine is running, the drum assembly 300 generates lateral vibration, causing the first moving part 1 of one vibration damping device 100 to move. Since the first moving part 1 is connected to the second moving part 2 of the adjacent vibration damping device 100, the vibration is transmitted to the adjacent vibration damping device 100. At this time, the two vibration damping devices 100 work together to absorb and buffer vibration energy.

[0107] In this embodiment, the series connection of adjacent vibration damping devices 100 enhances the vibration damping effect. With multiple vibration damping devices 100 connected in series, they interact with each other, enabling more comprehensive vibration damping of lateral vibrations of different frequencies and amplitudes. This improves the overall vibration damping performance of the garment processing equipment, prevents the cylinder assembly 300 from impacting the housing 200 due to excessive lateral vibration, extends the equipment's service life, and enhances the stability of equipment operation.

[0108] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
