Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, and in particular to a shock absorber and clothing processing equipment. Background Art

[0002] Existing drum washing machines mainly consist of a cabinet, an outer drum, and an inner drum. The outer drum is fixedly connected to the cabinet via springs and shock absorbers. Specifically, the top of the outer drum is fixedly connected to the top of the cabinet via springs, and the bottom of the outer drum is fixedly connected to the bottom of the cabinet via shock absorbers. The inner drum is rotatably mounted inside the outer drum.

[0003] During operation, the uneven distribution of clothes within the inner drum causes it to rotate, causing the outer drum to wobble up and down and side to side. The inclusion of hanging springs and shock absorbers reduces the intensity and amplitude of this swaying. In particular, the shock absorbers absorb and eliminate vibrations, preventing the washing machine from creeping, reducing noise, and thus ensuring performance and extending its lifespan.

[0004] Existing shock absorbers typically consist of a sleeve, a plunger, and a damping ring. In the assembled state, the damping ring is fixedly installed inside one end of the sleeve, and one end of the plunger passes through the damping ring and is inserted into the sleeve. As the outer drum of the washing machine shakes, the plunger extends and retracts relative to the sleeve. With the movement of the plunger, the damping ring and the plunger continuously rub against each other. The damping force generated by this friction resists the movement of the plunger, thereby reducing the amplitude of the outer drum vibration. However, these shock absorbers typically only provide damping along their length, without restricting the rotational freedom at both ends, resulting in poor damping performance. Utility Model Content

[0005] The purpose of this invention is to propose a shock absorber and clothing processing equipment, which solves the technical problem that existing shock absorbers only provide damping and shock absorption in the length direction and have no restriction on the rotational freedom at both ends, resulting in poor shock absorption effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a shock absorber, including a shock absorber body. The shock absorber body includes a sleeve, a plunger, and a first damping ring. The plunger is slidably inserted into the sleeve along the axial direction. The first damping ring is sleeved on the plunger and connected to the sleeve.

[0008] The shock absorber body has mounting holes at both ends, and each mounting hole has a rotating shaft that can rotate relative to the mounting hole. A second damping ring is provided between the rotating shaft and the inner wall of the mounting hole.

[0009] The shock absorber provides damping and vibration reduction along its length through a first damping ring between the plunger and the sleeve; and through a second damping ring between the mounting holes at both ends of the shock absorber body and the rotating shaft, it provides damping and vibration reduction for the rotational degree of freedom of the shock absorber, thus increasing the damping effect and improving the vibration reduction performance.

[0010] As a preferred embodiment of the above-mentioned shock absorber, a limiting stop is provided at one end of the mounting hole along its axial direction, the rotating shaft includes a shaft core and a circumferentially provided limiting step protruding from the shaft core, the second damping ring is sleeved on the outer periphery of the limiting step, and the limiting step and the second damping ring are located on one side of the limiting stop.

[0011] The setting of the limiting stop edge can limit the limiting step and the second damping ring to one side of the limiting stop edge, preventing the rotating shaft and the second damping ring from moving excessively toward the limiting stop edge.

[0012] As a preferred embodiment of the above-mentioned shock absorber, a cover plate is provided at the other end of the mounting hole along its axial direction, the shaft core passes through the cover plate, and the limiting step and the second damping ring are located between the cover plate and the limiting stop.

[0013] The cover plate and the limiting stop can limit the limiting step and the second damping ring between the cover plate and the limiting stop, preventing the limiting step and the second damping ring from moving in the axial direction of the shaft.

[0014] As a preferred embodiment of the above-mentioned shock absorber, a mounting groove is provided circumferentially at one end of the mounting hole where the cover plate is mounted, and the cover plate is accommodated in the mounting groove.

[0015] The mounting slot facilitates the installation of the cover plate.

[0016] As a preferred embodiment of the above-mentioned shock absorber, the cover plate has an annular structure, the inner diameter of the cover plate is smaller than the outer diameter of the limiting step, and the outer diameter of the cover plate is larger than the inner diameter of the second damping ring.

[0017] The above-mentioned configuration, through the cover plate, can provide axial limiting for the limiting step and the second damping ring.

[0018] As a preferred embodiment of the above-mentioned shock absorber, the shaft core is a hollow structure, and a limiting protrusion is provided inside the hollow structure.

[0019] The above configuration prevents the shaft from spinning freely when it is connected to other components.

[0020] As a preferred embodiment of the above-mentioned shock absorber, the first damping ring and the sleeve are detachably connected.

[0021] The first damping ring and the sleeve are detachably connected, which facilitates the assembly and disassembly of the first damping ring and the sleeve.

[0022] As a preferred embodiment of the above-mentioned shock absorber, one of the first damping ring and the sleeve is provided with a snap-fit ​​structure, and the other is provided with a snap-hole structure, wherein the snap-fit ​​structure can be snapped into the snap-hole structure.

[0023] The snap-fit ​​and snap-hole structures are simple in design, facilitating the detachable installation of the first damping ring and the sleeve.

[0024] As a preferred embodiment of the above-mentioned shock absorber, the snap-fit ​​structure protrudes from the first damping ring, and the cross-sectional thickness of the snap-fit ​​structure along the axial direction of the plunger gradually increases from the sleeve toward the plunger.

[0025] The aforementioned snap-fit ​​structure can guide the installation of the sleeve, so that the sleeve can be smoothly installed on the first damping ring.

[0026] This utility model also provides a garment processing device, which includes the above-mentioned shock absorber.

[0027] The garment processing device achieves good shock absorption through the aforementioned shock absorber.

[0028] The beneficial effects of this utility model are:

[0029] The shock absorber proposed in this utility model can provide damping and vibration reduction in the length direction of the shock absorber through the first damping ring between the plunger and the sleeve; and through the second damping ring between the mounting holes at both ends of the shock absorber body and the rotating shaft, it can provide damping and vibration reduction in the rotational freedom of the shock absorber, thereby increasing the damping effect of the shock absorber and making the vibration reduction effect better.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] Existing shock absorbers typically consist of a sleeve, a plunger, and a damping ring. In the assembled state, the damping ring is fixedly installed inside one end of the sleeve, and one end of the plunger passes through the damping ring and is inserted into the sleeve. As the outer drum of the washing machine shakes, the plunger extends and retracts relative to the sleeve. With the movement of the plunger, the damping ring and the plunger continuously rub against each other. The damping force generated by this friction resists the movement of the plunger, thereby reducing the amplitude of the outer drum vibration. However, these shock absorbers typically only provide damping along their length, without restricting the rotational freedom at both ends, resulting in poor damping performance.

[0050] To solve the above problems, such as Figures 1-5 As shown, this embodiment provides a shock absorber, including a shock absorber body 100. The shock absorber body 100 includes a sleeve 1, a plunger 2, and a first damping ring 3. The plunger 2 is slidably inserted into the sleeve 1 along the axial direction. The first damping ring 3 is sleeved on the plunger 2 and connected to the sleeve 1. Both ends of the shock absorber body 100 are provided with mounting holes 101. Each mounting hole 101 is provided with a rotating shaft 4 that can rotate relative to the mounting hole 101. A second damping ring 5 is provided between the rotating shaft 4 and the inner wall of the mounting hole 101. The resistance generated by friction between the second damping ring 5 and the rotating shaft 4 hinders the rotation of the rotating shaft 4 relative to the mounting hole 101.

[0051] The shock absorber can provide damping and vibration reduction in the length direction of the shock absorber through the first damping ring 3 between the plunger 2 and the sleeve 1; and through the second damping ring 5 between the mounting holes 101 at both ends of the shock absorber body 100 and the rotating shaft 4, it can provide damping and vibration reduction in the rotational degree of freedom of the shock absorber, thereby increasing the damping effect of the shock absorber and making the vibration reduction effect better.

[0052] Specifically, if Figures 3-5 As shown, a limit stop 102 is provided at one end of the mounting hole 101 along its axial direction, such as... Figure 5 As shown, the rotating shaft 4 includes a shaft core 41 and a circumferentially arranged limiting step 42 protruding from the shaft core 41. A second damping ring 5 is sleeved on the outer periphery of the limiting step 42, and the limiting step 42 and the second damping ring 5 are limited to one side of the limiting stop 102. The limiting stop 102 ensures that the limiting step 42 and the second damping ring 5 are limited to one side of the limiting stop 102, preventing the rotating shaft 4 and the second damping ring 5 from moving excessively toward the limiting stop 102. A cover plate 6 is provided at the other end of the mounting hole 101 along its axial direction. The shaft core 41 passes through the cover plate 6, and the limiting step 42 and the second damping ring 5 are limited between the cover plate 6 and the limiting stop 102. The cover plate 6 and the limiting stop 102 limit the limiting step 42 and the second damping ring 5 between the cover plate 6 and the limiting stop 102, preventing the limiting step 42 and the second damping ring 5 from moving along the axial direction of the rotating shaft 4.

[0053] Furthermore, such as Figure 4 As shown, a mounting groove 103 is provided circumferentially at the end of the mounting hole 101 where the cover plate 6 is mounted, and the cover plate 6 is accommodated within the mounting groove 103. The mounting groove 103 facilitates the installation of the cover plate 6. The cover plate 6 can be installed in the mounting groove 103 by interference fit or by adhesive bonding. Alternatively, internal threads can be provided on the inner wall of the mounting groove 103, and external threads can be provided on the outer circumferential wall of the cover plate 6, allowing the cover plate 6 to be installed in the mounting groove 103 via threaded connection. It should be noted that the method of installing the cover plate 6 in the mounting groove 103 is not specifically limited here, as long as the cover plate 6 can be installed in the mounting groove 103 and the second damping ring 5 can be prevented from dislodging.

[0054] In this embodiment, the cover plate 6 is an annular structure. The inner diameter of the cover plate 6 is smaller than the outer diameter of the limiting step 42, and the outer diameter of the cover plate 6 is larger than the inner diameter of the second damping ring 5. The above arrangement allows the cover plate 6 to axially limit the limiting step 42 and the second damping ring 5.

[0055] like Figure 5As shown, the shaft core 41 has a hollow structure, and a limiting protrusion 411 is provided inside the hollow structure. This design prevents the shaft 4 from spinning freely when connected to other components. In this embodiment, the limiting protrusion 411 and the inner wall of the shaft core 41 are integrally formed. Preferably, the limiting protrusion 411 has an arc-shaped structure, with the arc of the arc fitting snugly against and connecting to the inner cavity of the shaft core 41, and the chord of the arc of the arc facing the center of the shaft core 41.

[0056] Optionally, the first damping ring 3 and the sleeve 1 are detachably connected to facilitate the assembly and disassembly of the first damping ring 3 and the sleeve 1. For example... Figures 1-3 As shown, the first damping ring 3 is detachably connected to the end of the sleeve 1 that does not have the second damping ring 5. Specifically, as... Figure 6 As shown, the first damping ring 3 includes a ring structure 31 and a limiting ring 32 disposed on the ring structure 31. The limiting ring 32 is disposed on the outer periphery of the end of the ring structure 31. The ring structure 31 extends into the sleeve 1. The limiting ring 32 abuts against the end face of the sleeve 1, thereby limiting the installation of the first damping ring 3.

[0057] Optionally, one of the first damping ring 3 and the sleeve 1 is provided with a snap-fit ​​structure 30, and the other is provided with a snap-fit ​​structure 11. The snap-fit ​​structure 30 can be snapped into the snap-fit ​​structure 11. The snap-fit ​​structure 30 and the snap-fit ​​structure 11 have simple structures, which facilitates the detachable installation of the first damping ring 3 and the sleeve 1.

[0058] In this embodiment, the snap-fit ​​structure 30 protrudes from the ring structure 31 of the first damping ring 3, and the snap-fit ​​structure 11 is disposed on the sleeve 1. The cross-sectional thickness of the snap-fit ​​structure 30 along the axial direction of the plunger 2 gradually increases from the sleeve 1 toward the plunger 2, which plays a guiding role in the installation of the sleeve 1 so that the sleeve 1 can be smoothly installed on the first damping ring 3.

[0059] In this embodiment, two sets of snap-fit ​​structures 30 are provided on the outer periphery of the first damping ring 3. The two sets of snap-fit ​​structures 30 are equally spaced along the outer periphery of the first damping ring 3. Correspondingly, two sets of locking holes 11 are also provided on the sleeve 1. The locking holes 11 are provided in a one-to-one correspondence with the snap-fit ​​structures 30. In other embodiments, the number of sets of snap-fit ​​structures 30 and locking holes 11 is not limited to two sets. Three, four or more sets can also be provided. No specific limitation is made here.

[0060] This embodiment also provides a garment processing device, which includes the aforementioned shock absorber. This garment processing device achieves a good shock absorption effect through the shock absorber.

[0061] In this embodiment, the clothing handling device is a washing machine, which includes a cabinet, an outer drum, and an inner drum. The outer drum is fixedly connected to the cabinet via a spring and a shock absorber. Specifically, the top of the outer drum is fixedly connected to the top of the cabinet via a spring, and the bottom of the outer drum is fixedly connected to the bottom of the cabinet via a shock absorber. The inner drum is rotatably disposed within the outer drum.

[0062] During operation, the uneven distribution of clothes within the inner drum causes it to rotate, causing the outer drum to wobble up and down and side to side. The inclusion of hanging springs and shock absorbers reduces the intensity and amplitude of this swaying. In particular, the shock absorbers absorb and eliminate vibrations, preventing the washing machine from creeping, reducing noise, and thus ensuring performance and extending its lifespan.

[0063] As the outer drum of the washing machine shakes, the plunger 2 extends and retracts relative to the sleeve 1 and the first damping ring 3. With the movement of the plunger 2, the first damping ring 3 continuously rubs against the plunger 2. The damping force generated by the friction between the first damping ring 3 and the plunger 2 hinders the axial movement of the plunger 2, thereby reducing the amplitude of the outer drum vibration. The second damping rings 5 ​​at both ends of the shock-absorbing body 100 continuously rub against the rotating shaft 4. The resistance generated by the second damping rings 5 ​​and the rotating shaft 4 hinders the rotation of the rotating shaft 4 relative to the mounting hole 101, thus restricting the rotational freedom and improving the shock absorption effect of the washing machine.

[0064] In other embodiments, the clothing handling device is not limited to a washing machine, but can also be a dryer, etc.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
