Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a clothing processing device and a shock absorbing device thereof. Background Art

[0002] The current development trend of drum washing machines is toward large-capacity, ultra-thin embedded platforms. These platforms require a large barrel diameter and a thin chassis. The gap between the outer barrel and the chassis is shrinking. This can cause the washing machine to collide with the chassis and shift when passing through the resonant speed range during operation. This requires increased damping of the supports between the outer barrel and the chassis. This increased damping of the supports results in high low-frequency structural noise. The current noise reduction method involves attaching sound-absorbing material to the interior of the washing machine chassis. However, since this noise has a low frequency (typically below 200Hz), the use of sound-absorbing material would require a very large size, making this impractical given the limited space inside the chassis.

DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0048] The following combination Figures 1 to 16 The clothes processing device and the shock absorbing device thereof according to the embodiment of the present utility model are described in detail.

[0049] Reference Figures 1 to 4 As shown, some embodiments of the present invention provide a clothes processing device comprising a housing and a tub 1 disposed within the housing. The tub 1 may specifically comprise an outer tub and an inner tub rotatably disposed within the outer tub. Specifically, the tub 1 may be suspended within the housing using a plurality of suspension springs 8. When the inner tub rotates and causes the outer tub to vibrate, the suspension springs 8 can reduce the vibration amplitude of the outer tub and reduce noise.

[0050] In order to enhance the shock absorption effect, a number of support members 3 are provided at the bottom of the barrel body 1. One end of the support member 3 is connected to the barrel body 1. A support base 2 (also referred to as a box reinforcement member) is provided at the bottom of the inner body of the box. The support base 2 can be fixed to the box body via a foot 7. The other end of the support member 3 is connected to the support base 2, thereby achieving the connection between the support member 3 and the support base 2. Specifically, the interior of the support member 3 can have a damping structure. When the inner barrel rotates and generates vibration, the support member 3 can consume the vibration energy of the barrel body 1, reducing the vibration transmitted from the barrel body 1 to the support base 2, thereby reducing vibration noise, achieving a shock absorption and noise reduction effect, and improving user experience.

[0051] However, as drum washing machines develop towards large-capacity ultra-thin embedded platforms, the ultra-thin embedded platforms need to have large barrel diameters and thin bodies. The gap between the outer barrel and the body is getting smaller and smaller. When the washing machine passes through the resonant speed range during operation, the body will be displaced due to collision. This requires increasing the damping of the support member 3. However, increasing the damping of the support member 3 will result in high low-frequency noise of the structure.

[0052] Based on this, some embodiments of the present invention provide a shock absorbing device for a clothing processing device to solve the problem of high low-frequency noise during operation of the clothing processing device (eg, a drum washing machine).

[0053] Reference Figures 1 to 16 As shown, some embodiments of the present invention provide a shock absorbing device for a clothing processing apparatus, comprising a support base 2, a support member 3, a shock absorbing element 4 and a fastener.

[0054] One end of the support member 3 is used to connect to the barrel body 1, and the other end is provided with a connecting collar 31, which is connected to the support base 2 provided in the box body through the connecting collar 31, thereby connecting the support member 3 between the barrel body 1 and the support base 2. Specifically, the support member 3 can be connected to the support base 2 by a fastener, which passes through the connecting collar 31 on the support member 3 and is fixed to the support base 2, thereby fixing the support member 3 on the support base 2.

[0055] In specific implementation, in order to enhance the shock absorption and noise reduction effect, the interior of the support member 3 can have a damping structure. When the inner barrel rotates and generates vibration, the support member 3 can consume the vibration energy of the barrel body 1, reducing the vibration transmitted from the barrel body 1 to the support seat 2, thereby reducing the vibration noise.

[0056] The shock absorbing element 4 is a sleeve-shaped structure, and the shock absorbing element 4 can be sleeved on the fastener, or the fastener can pass through the shock absorbing element 4. Specifically, the shock absorbing element 4 can be arranged adjacent to the support member 3, or in other words, the shock absorbing element 4 can be located on one side of the support member 3. During installation, the fastener can sequentially pass through the connecting collar 31 on the support member 3 and the sleeve-shaped shock absorbing element 4 and be fixed to the support base 2, thereby achieving the support member 3 and the shock absorbing element 4 being fixed to the support base 2 via the fastener.

[0057] With such a configuration, the vibration of the support member 3 can be transmitted to the shock-absorbing element 4 through the fastener, thereby absorbing the vibration through the shock-absorbing element 4. That is to say, by providing the shock-absorbing element 4, the vibration that the support member 3 would have directly transmitted to the support seat 2 can be better transmitted to the shock-absorbing element 4, and the vibration transmitted from the support member 3 can be absorbed by the shock-absorbing element 4, thereby better reducing the vibration transmitted from the support member 3 to the support seat 2, and then reducing the vibration noise, achieving a better shock-absorbing and noise reduction effect, and improving the user experience.

[0058] To effectively transmit the vibration of support member 3 to damping element 4 via the fastener, damping element 4 can be fixedly connected to the fastener. Specifically, the inner surface of damping element 4 can be provided with internal threads, and the fastener can be provided with external threads. Shock-absorbing element 4 is sleeved on the fastener and fixedly connected to the fastener with threads. Of course, damping element 4 and the fastener can also be connected and fixed by welding or interference fit.

[0059] In a specific implementation, the shock-absorbing element 4 may include an inner ring layer 41, with a shock-absorbing structure formed around the periphery of the inner ring layer 41. That is, the shock-absorbing element 4 may include the inner ring layer 41 and the shock-absorbing structure formed around the periphery of the inner ring layer 41. The inner ring layer 41 may be used to connect to the fastener, and the shock-absorbing structure may achieve a vibration and noise reduction effect.

[0060] Exemplarily, the shock-absorbing element 4 may include at least two ring layers, which are arranged in sequence, and the innermost ring layer can be used to connect with the fastener. All ring layers or part of the ring layers are constructed into a shock-absorbing structure, or in other words, all ring layers or part of the ring layers form a shock-absorbing system.

[0061] Specifically, the inner ring layer 41 of the shock-absorbing element 4 can be rigidly connected to the fastener, so that the vibration transmitted from the support member 3 to the fastener can be better transmitted to the shock-absorbing element 4, thereby reducing the vibration of the support member 3 that would otherwise be directly transmitted to the support seat 2 through the fastener; a shock-absorbing structure is formed on the periphery of the inner ring layer 41 of the shock-absorbing element 4 to absorb the vibration transmitted to the shock-absorbing element 4 through the shock-absorbing structure of the shock-absorbing element 4, thereby reducing the vibration of the support seat 2 and reducing vibration noise.

[0062] In a specific implementation, the inner ring layer 41 of the shock-absorbing element 4 and the fastener can both be made of metal parts. The inner ring layer 41 of the shock-absorbing element 4 and the fastener can be fixed by threaded connection, welding connection, interference fit fixation or other connection methods to achieve a rigid connection between the shock-absorbing element 4 and the fastener. On the one hand, the use of fasteners made of metal can improve the connection strength between the support member 3 and the shock-absorbing element 4 and the support seat 2. On the other hand, the rigid connection between the shock-absorbing element 4 and the fastener can better transmit the vibration transmitted from the support member 3 to the fastener to the shock-absorbing element 4, thereby utilizing the shock-absorbing element 4 to absorb vibration and reduce vibration noise, especially reduce low-frequency vibration noise.

[0063] It should be noted that the shock-absorbing structure (or shock-absorbing system) formed on the shock-absorbing element 4 can specifically utilize the collision energy dissipation principle to reduce the vibration transmitted from the support member 3 to the support base 2; it can also utilize the resonance energy dissipation principle to reduce the vibration transmitted from the support member 3 to the support base 2; it can also utilize the collision energy dissipation principle combined with the resonance energy dissipation principle to reduce the vibration transmitted from the support member 3 to the support base 2. Of course, other shock-absorbing principles can also be utilized according to actual needs to reduce the vibration transmitted from the support member 3 to the support base 2.

[0064] The shock absorbing device of the clothing processing equipment provided by the present invention is provided with a support member 3 and a shock absorbing element 4. One end of the support member 3 is connected to the barrel body 1, and the other end is fixed to the support seat 2 by a fastener, so that the barrel body 1 is supported on the support seat 2 by the support member 3; the shock absorbing element 4 is a sleeve-shaped structure, and the fastener passes through the connecting ring 31 of the support member 3 and the shock absorbing element 4, and is fixed to the support seat 2. With such a configuration, the vibration of the support member 3 can be transmitted to the shock absorbing element 4 through the fastener, thereby absorbing the vibration through the shock absorbing element 4. That is to say, by providing the shock absorbing element 4, the vibration that would have been directly transmitted to the support seat 2 by the support member 3 can be better transmitted to the shock absorbing element 4, and the vibration transmitted from the support member 3 is absorbed by the shock absorbing element 4, thereby better reducing the vibration transmitted to the support seat 2 by the support member 3, and then reducing the vibration noise, achieving a better shock absorption and noise reduction effect, and improving the user experience.

[0065] In some embodiments, reference Figure 4 、 Figure 5 、 Figure 12 and Figure 13 As shown, the fasteners include a fastening bolt 5 and a fastening nut 6; a connecting ear 21 is provided on the support base 2, specifically, the connecting ear 21 can be a connecting ear 21 extending vertically upward relative to the support base 2, the connecting ear 21 can be fixed on the support base 2 as an independent component, or it can be formed by bending and tilting part of the support base 2 upward; the fastening bolt 5 passes through the connecting collar 31, the shock absorbing element 4 and the connecting ear 21, and is tightened and fixed to the support base 2 by the fastening nut 6; this arrangement is used to realize the installation and fixation of the support member 3 and the shock absorbing element 4 on the support base 2.

[0066] Specifically, the number of connecting ears 21 can be one or two. When the number of connecting ears 21 is two, the two connecting ears 21 can be arranged opposite to each other and spaced apart, and the connecting ring 31 of the support member 3 and the shock-absorbing element 4 can be arranged between the two connecting ears 21; when the number of connecting ears 21 is one, the connecting ring 31 of the support member 3 and the shock-absorbing element 4 can be arranged on the same side of the connecting ear 21.

[0067] In a specific implementation, the inner surface of the shock-absorbing element 4 is provided with an internal thread, which is adapted to the external thread provided on the outer surface of the fastening bolt 5. The shock-absorbing element 4 is threadedly connected and fixed to the fastening bolt 5 through the internal thread. This arrangement is used to achieve the connection and fixation of the shock-absorbing element 4 and the fastening bolt 5.

[0068] During specific assembly, the connecting collar 31 of the support member 3 and the shock-absorbing element 4 can be placed between the two connecting ears 21, and the fastening bolt 5 can be passed through one of the connecting ears 21, the connecting collar 31, the shock-absorbing element 4 and the other connecting ear 21 from one side in sequence. At the same time, the fastening bolt 5 can be inserted while the fastening bolt 5 is screwed to ensure that the fastening bolt 5 passes through the shock-absorbing element 4 smoothly and is threadedly connected with the internal thread on the shock-absorbing element 4. After the fastening bolt 5 is passed through, the fastening nut 6 is installed on the passing end of the fastening bolt 5 and tightened, so that the support member 3 and the shock-absorbing element 4 are fixed on the support seat 2, and the shock-absorbing element 4 is connected and fixed to the fastener.

[0069] Of course, the connection and fixing method between the shock absorbing element 4 and the fastener is not limited to threaded connection and fixing, and welding, interference fit and other methods can also be used to achieve connection and fixing.

[0070] In some embodiments, the shock absorbing element 4 includes at least two ring layers, the innermost ring layer is fixedly connected to the fastener, and all the ring layers or some of the ring layers form a shock absorbing system; in other words, all the ring layers or some of the ring layers are constructed into a shock absorbing structure.

[0071] Specifically, the shock absorbing element 4 may include two, three, or more layers, and the multiple layers of the shock absorbing element 4 may be arranged in a sequentially nested manner. For example, the shock absorbing element 4 may include two layers, namely an inner layer and an outer layer, with the outer layer nested around and connected to the inner layer. The shock absorbing element 4 may also include three layers, namely an inner layer, an intermediate layer, and an outer layer, with the intermediate layer nested around the inner layer, the outer layer nested around the intermediate layer, and the intermediate layer connected between the inner and outer layers.

[0072] With such a configuration, the shock-absorbing element 4 can be fixedly connected to the fastener through its innermost circle layer, so that the vibration transmitted from the support member 3 to the fastener can be better transmitted to the shock-absorbing element 4, thereby reducing the vibration that the support member 3 would otherwise transmit directly to the support seat 2 through the fastener; all or part of the circle layers of the shock-absorbing element 4 can be constructed into a shock-absorbing structure to absorb the vibration transmitted to the shock-absorbing element 4 through the shock-absorbing structure of the shock-absorbing element 4, thereby reducing the vibration of the support seat 2 and reducing vibration noise.

[0073] In some embodiments, reference Figures 1 to 8As shown, the shock absorbing element 4 includes a sleeve-shaped shell body 40 , and a cavity structure is formed inside the shell body 40 . The cavity structure can be formed into a shock-absorbing energy-absorbing cavity to better absorb the vibration transmitted to the shock absorbing element 4 .

[0074] Specifically, the cavity structure can be filled with collision energy absorbing members 44 (e.g., steel balls). When the clothes processing device is in operation (e.g., when a drum washing machine is spinning), the drum body 1 vibrates, causing the collision energy absorbing members 44 in the cavity structure to vibrate, collide, and rub against each other. The collision energy absorbing members 44 also collide with the shell body 40, thereby consuming energy and achieving a shock absorption effect, thereby reducing the vibration of the support base 2 and the box connected to the support base 2, thereby reducing vibration noise.

[0075] In some embodiments, reference Figures 4 to 8 As shown, the shock absorbing element 4 includes an inner ring layer 41 , an outer ring layer 42 and a plurality of spacer ribs 43 connected between the inner ring layer 41 and the outer ring layer 42 .

[0076] Specifically, the outer ring layer 42 is located outside the inner ring layer 41 and can be spaced apart from the inner ring layer 41 to form a circular cavity structure between the inner ring layer 41 and the outer ring layer 42. A plurality of spacing ribs 43 are connected between the inner ring layer 41 and the outer ring layer 42, or in other words, a plurality of spacing ribs 43 are located in the cavity area formed between the inner ring layer 41 and the outer ring layer 42, so as to better absorb the vibration transmitted to the shock absorbing element 4 through the cavity structure formed between the inner ring layer 41 and the outer ring layer 42.

[0077] In some embodiments, reference Figures 4 to 8 As shown, a plurality of spacer ribs 43 separate the area between the inner ring layer 41 and the outer ring layer 42 into a plurality of cavities 45 , and the cavities 45 are filled with collision energy absorbing members 44 .

[0078] It should be noted that, referring to Figure 4 and Figure 5 As shown, the shock absorbing element 4 is a sleeve-shaped structure, and the shock absorbing element 4 is sleeved on the bolt, and the axial direction of the shock absorbing element 4 is also the axial direction of the bolt. Figures 6 to 8 As shown, the DD direction is the cross section of the shock absorbing element 4 in the axial direction, and the EE direction is the cross section of the shock absorbing element 4 in the cross-sectional direction.

[0079] Among them, the inner ring layer 41 of the shock-absorbing element 4 is used to be rigidly connected to a fastener (such as a bolt) by means of a threaded connection or the like. The inner ring layer 41 and the spacing ribs 43, the outer ring layer 42 and the collision energy absorbing member 44 located on the periphery of the inner ring layer 41 together form a shock-absorbing structure, so that the collision energy absorbing member 44 collides and rubs against each other in the cavity 45 jointly constructed by the inner ring layer 41, the outer ring layer 42 and the spacing ribs 43, thereby achieving the purpose of friction collision energy consumption and thus reducing the vibration of the shock-absorbing element 4; and, through the separation of multiple cavities 45, the displacement of the collision energy absorbing member 44 can be limited, thereby avoiding excessive displacement of the collision energy absorbing member 44 in the cavity 45 and affecting the shock-absorbing effect.

[0080] In some embodiments, reference Figure 8 As shown, the spacing ribs 43 include radial spacing ribs 43, and multiple radial spacing ribs 43 are arranged at intervals along the circumference of the inner ring layer 41 to separate the area between the inner ring layer 41 and the outer ring layer 42 into multiple cavities 45 with the same number as the spacing ribs 43 through multiple radial spacing ribs 43.

[0081] In order to achieve a good shock-absorbing effect, the number of cavities 45 separated between the inner ring layer 41 and the outer ring layer 42 is greater than or equal to 6, so as to avoid the situation where the number of separated cavities 45 is too small, resulting in excessive displacement of the collision energy absorbing member 44 in the cavity 45 and affecting the shock-absorbing effect.

[0082] For example, referring to Figure 8 As shown, the number of cavities 45 separated between the inner layer 41 and the outer layer 42 is 6. Of course, in a specific implementation, the number of cavities 45 separated between the inner layer 41 and the outer layer 42 is not limited to being greater than or equal to 6, and can also be set to less than 6 as needed.

[0083] In other embodiments, the spacing ribs 43 include circumferential spacing ribs 43 and radial spacing ribs 43. The circumferential spacing ribs 43 are arranged around the inner ring layer 41 and divide the area between the inner ring layer 41 and the outer ring layer 42 into an inner cavity area and an outer cavity area. The radial spacing ribs 43 are connected between the circumferential spacing ribs 43 and the inner ring layer 41, or between the circumferential spacing ribs 43 and the outer ring layer 42. This arrangement allows the circumferential spacing ribs 43 to divide the area between the inner ring layer 41 and the outer ring layer 42 into an inner and an outer layer. The circumferential spacing ribs 43 cooperate with the radial spacing ribs 43 to increase the number of cavities 45 formed, thereby improving the vibration and noise reduction effects.

[0084] It should be noted that, considering the installation space of the shock absorbing element 4 on the support base 2, the number of inner and outer layers of the shock absorbing element 4 divided by the circumferential spacing ribs 43 is less than or equal to two layers. That is, the inner and outer layers 41 and 42 of the shock absorbing element 4 can be separated into only one cavity area, or two cavity areas can be separated by a circle of circumferential spacing ribs 43. Of course, if factors such as installation space are not considered, the number of cavity areas can also be greater than two layers.

[0085] In addition, refer to Figure 7 As shown, the shell body 40 of the shock-absorbing element 4 may include the above-mentioned inner ring layer 41, outer ring layer 42 and spacer ribs 43, and may also include a cover plate 46, which covers the two axial ends of the inner ring layer 41 and the outer ring layer 42 to enclose the shock-absorbing and energy-absorbing parts in the cavity structure formed on the shell body 40.

[0086] In some embodiments, reference Figure 7 and Figure 8 As shown, the collision energy absorbing member 44 is a steel ball. The steel ball has a high density and weight and is easy to roll in the cavity 45. When the steel ball rubs and collides, it has a large force, thereby achieving the purpose of effectively consuming energy and reducing the vibration of the shock absorbing element 4.

[0087] In other embodiments, the collision energy absorber 44 is a steel ball covered with a damping shell. This arrangement, on the one hand, can take advantage of the high density and weight of the steel ball to effectively dissipate energy when the steel balls collide; on the other hand, the damping shell covering the outer surface of the steel ball can reduce the collision noise generated by the steel balls.

[0088] Of course, in a specific implementation, the specific material of the collision energy absorbing member 44 is not limited to the above-mentioned definition, and can be reasonably selected and adjusted according to actual conditions.

[0089] In some embodiments, the diameter of the collision energy absorbing member 44 is less than or equal to 2 mm, and the filling rate of the collision energy absorbing member 44 in the cavity 45 is greater than or equal to 85% and less than or equal to 90%.

[0090] For example, if the collision energy absorber 44 is a steel ball, the diameter of the steel ball is less than or equal to 2 mm. This prevents the problem of a too small diameter resulting in a small collision force and ineffective energy dissipation. It also prevents the problem of a too large diameter resulting in a small number of steel balls being accommodated in the cavity 45 and affecting the overall collision energy absorption. The filling rate of the cavity 45 with steel balls is greater than or equal to 85% and less than or equal to 90%. This prevents the problem of a too small filling rate affecting the overall collision energy absorption and the problem of a too large filling rate limiting the displacement of the steel balls and affecting the collision force generated during a collision.

[0091] Of course, in a specific implementation, the size parameters and filling rate of the collision energy absorbing member 44 can be reasonably adjusted according to actual conditions.

[0092] In some embodiments, the shell body 40 of the shock-absorbing element 4 is entirely made of metal. This ensures that the inner ring 41 of the shock-absorbing element 4 is rigidly connected to the fastener, thereby ensuring that more vibration of the support member 3 is transmitted to the shock-absorbing element 4 through the fastener. Furthermore, this ensures that when the collision energy absorber 44 collides with the shock-absorbing element 4, it can better dissipate energy, thereby achieving the purpose of vibration absorption and noise reduction.

[0093] In other embodiments, referring to Figures 9 to 16 As shown, the shock absorbing element 4 includes an inner ring layer 41, an intermediate layer 47 and an outer ring layer 42. The intermediate layer 47 is connected between the inner ring layer 41 and the outer ring layer 42. The intermediate layer 47 is made of a flexible material, and the outer ring layer 42 is made of a rigid material.

[0094] It should be noted that, referring to Figure 12 and Figure 13 As shown, the shock absorbing element 4 is a sleeve-shaped structure, and the shock absorbing element 4 is sleeved on the bolt, and the axial direction of the shock absorbing element 4 is also the axial direction of the bolt. Figures 14 to 16 As shown, the II direction is the cross section of the shock absorbing element 4 in the axial direction, and the JJ direction is the cross section of the shock absorbing element 4 in the sectional direction.

[0095] Among them, the inner ring layer 41 of the shock-absorbing element 4 is mainly used for connection and fixation. The shock-absorbing element 4 is rigidly connected to the fasteners (such as bolts) through the inner ring layer 41 by means of threaded connection, thereby ensuring that the vibration of the support 3 is transmitted to the shock-absorbing element 4 more through the fasteners; the middle layer 47 and the outer ring layer 42 can jointly form a shock-absorbing structure. Specifically, the inner ring layer 41 is a flexible material, and the outer ring layer 42 is a rigid material. The inner ring layer 41 and the outer ring layer 42 can jointly form a shock-absorbing system. When the barrel body 1 vibrates during operation, it will cause the support 3 to vibrate. When the damping force of the support 3 is transmitted to the shock-absorbing element 4 through the fasteners, the middle layer 47 and the outer ring layer 42 of the shock-absorbing element 4 will vibrate. By utilizing the principle of resonance energy dissipation, it can not only absorb the vibration energy transmitted by the support 3, but also the reaction force generated by the shock-absorbing element 4 can reduce the vibration of the support base 2, thereby reducing the vibration of the barrel body 1 transmitted to the support base 2 and the box through the support 3, thereby avoiding the vibration of the support base 2 and the box to generate radiation noise.

[0096] In a specific embodiment, the inner ring layer 41 is made of metal, the middle layer 47 is made of rubber, and the outer ring layer 42 is also made of metal. The inner ring layer 41, the middle layer 47, and the outer ring layer 42 are connected by vulcanization. Specifically, the inner surface of the inner ring layer 41 is provided with internal threads, which are threadedly connected to the shock absorbing element 4 via bolts. The middle layer 47 can be made of a relatively soft rubber material, and the outer ring layer 42 is made of metal. The middle layer 47 and the outer ring layer 42 together form a shock absorbing system. Of course, the specific materials of the inner ring layer 41, the middle layer 47, and the outer ring layer 42 are not limited to the above and can be reasonably set and adjusted according to actual needs.

[0097] In some embodiments, the middle layer 47 and outer ring layer 42 together form a shock-absorbing system, and the natural frequency of the shock-absorbing system is the same as the frequency corresponding to the operation of the clothing processing device at a set operating speed. For example, the operating speed of the clothing processing device in the dehydration state is 1320 rpm, corresponding to a frequency of 22 Hz. Setting the natural frequency of the shock-absorbing system to 22 Hz can better reduce vibrations at this frequency, thereby achieving the purpose of reducing low-frequency vibrations. Of course, the natural frequency of the shock-absorbing system formed by the middle layer 47 and outer ring layer 42 is not limited to the above definition and can be reasonably set and adjusted based on the corresponding frequencies of the clothing processing device at other operating speeds.

[0098] To ensure the shock-absorbing effectiveness of the shock-absorbing system formed by the intermediate layer 47 and the outer ring layer 42, in some embodiments, the ratio of the mass of the outer ring layer 42 to the mass of the support base 2 is greater than or equal to 0.05 and less than or equal to 0.15. In other words, the ratio of the weight of the outer ring layer 42 to the weight of the support base 2 is greater than or equal to 0.05 and less than or equal to 0.15. This configuration avoids the problem of the outer ring layer 42 being too small, thereby affecting the shock-absorbing effect, while also avoiding the problem of the outer ring layer 42 being too large, thereby increasing the overall weight and volume of the shock-absorbing element 4 and making it difficult to install.

[0099] It should be noted that, if weight and volume are not a concern, the mass of the outer ring layer 42 can be appropriately increased, that is, the weight of the outer ring layer 42 can be appropriately increased to achieve a better shock absorption effect. The thickness dimensions of the inner ring layer 41, the intermediate layer 47, and the outer ring layer 42 are not specifically limited. While ensuring the secure connection between the inner ring layer 41 and the fasteners, the thickness dimensions of the inner ring layer 41 and the intermediate layer 47 can be appropriately reduced to provide sufficient space for the outer ring layer 42 and ensure that the outer ring layer 42 has sufficient weight to achieve a good shock absorption effect.

[0100] In some embodiments, the axial dimension of the inner ring layer 41 is greater than or equal to the axial dimension of the outer ring layer 42, and the axial dimension of the outer ring layer 42 is greater than or equal to the axial dimension of the middle layer 47. In other words, the axial dimension of the middle layer 47 is set to be the shortest, so that the vibration of the middle layer 47 can be better transmitted to the outer ring layer 42.

[0101] In some embodiments, a cavity structure is provided in the inner ring layer 41, and a collision energy absorbing member 44 is provided in the cavity structure. This arrangement can achieve better shock absorption and energy absorption effect by combining the resonance energy absorption principle with the collision energy absorption principle.

[0102] Other embodiments of the present invention provide a clothing processing device, including a box body, a barrel body 1 and a shock-absorbing device of the clothing processing device as any of the above embodiments, wherein the barrel body 1 is arranged in the box body, and the shock-absorbing device is arranged between the barrel body 1 and the box body.
