Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a shock absorbing device and a clothing processing device. Background Art

[0002] Home appliances generate vibrations during operation, and the noise caused by the vibrations reduces the user experience. Currently, the relevant technology reduces the vibration noise of home appliances by installing a friction plate in the sleeve of the shock absorber. However, since the sleeve is an integrated structure, the friction plate can only be installed at one end of the sleeve. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention is to provide a shock absorbing device.

[0005] A second aspect of the present invention is to provide a clothes treating device.

[0006] In view of this, according to a first aspect of the present invention, a shock absorbing device is provided, which includes a plurality of sleeves, a piston rod, at least one damping member and a vent, wherein each sleeve of the plurality of sleeves is connected in sequence to form a piston cavity. At least a portion of the piston rod extends into the piston cavity and can move relative to the sleeve. At least one damping member is provided on the inner wall of at least one sleeve of the plurality of sleeves, and the piston rod can contact the at least one damping member. The vent is provided on at least one sleeve of the plurality of sleeves and is connected to the piston cavity.

[0007] The shock absorbing device provided by the embodiment of the present invention includes a plurality of sleeves, a piston rod, at least one damping member and a vent. Specifically, each sleeve is detachably connected in sequence, which is convenient for installation and disassembly. In addition, when a sleeve among the plurality of sleeves of the shock absorbing device fails, it is only necessary to directly replace the failed sleeve, which can avoid the problem that when a certain part of the sleeve formed in one piece in the related art fails, the entire sleeve needs to be replaced, thereby reducing the cost of use. The number of damping members is at least one, and specifically, the damping member is arranged on the inner wall of at least one sleeve among the plurality of sleeves, that is, the number of damping members can be one or more. The plurality of damping members can be arranged on one sleeve in a concentrated manner, or can be arranged on a plurality of sleeves in a dispersed manner, and the specific arrangement of the damping members can be designed according to actual needs. Furthermore, the plurality of sleeves can form a piston cavity, at least a portion of the piston rod can extend into the piston cavity, and the piston rod can move relative to the plurality of sleeves. When the piston rod moves in and out of the multiple sleeves, the piston rod can contact at least one damping member and generate friction, thereby hindering the relative movement of the piston rod, thereby reducing the vibration generated by the clothing processing device with the shock absorbing device during operation, thereby achieving the purpose of reducing the vibration noise of the clothing processing device. By arranging a sleeve into a structure in which multiple sleeves are detachably connected in sequence, damping members can be arranged at multiple positions of the sleeve to achieve a better noise reduction effect, and the multiple sleeves can be detachably connected, which can also facilitate the maintenance and replacement of the damping member.

[0008] In addition, by arranging damping members at various positions of the plurality of sleeves, the piston rod can contact the damping members at various positions during the movement process. When a large vibration occurs during the operation of the clothing processing device, or when the clothing processing device resonates, the amplitude of the shock absorbing device is longer, that is, the movement stroke of the piston rod is larger, that is, the number of damping members contacted by the piston rod is larger, and the friction force generated between the plurality of damping members and the piston rod is larger, so that the vibration amplitude of the clothing processing device can be effectively controlled, thereby reducing the vibration noise of the clothing processing device. When the vibration occurring during the operation of the clothing processing device is smaller, or when the clothing processing device does not resonate, the amplitude of the shock absorbing device is smaller, that is, the movement stroke of the piston rod is shorter, that is, the number of damping members contacted by the piston rod is smaller, for example, only one damping member is contacted, and the friction resistance generated between the smaller damping members and the piston rod can achieve the effect of controlling the vibration noise of the clothing processing device. That is, by arranging damping members at various positions of the plurality of sleeves, different friction resistances can be generated according to the vibration amplitude of the clothing processing device to reduce the vibration noise of the clothing processing device.

[0009] It should be noted that the damping member may be an elastic member, which may not only generate friction resistance when in contact with the piston rod, but also buffer the movement of the piston rod in and out of the multiple sleeves. Specifically, when the clothing processing device is working and vibrating, the piston rod moves in and out of the multiple sleeves. By setting the damping member as an elastic member, when the amplitude of the vibration of the clothing processing device is large, the impact force of the piston rod on the multiple sleeves can be reduced, and the effect of reducing vibration noise of the shock absorbing device can be further improved. In addition, the damping member has a through hole, and the multiple sleeves form a piston cavity. The diameter of the through hole can be slightly smaller than the diameter of the piston cavity, so that the piston rod can avoid contact with the inner wall of the multiple sleeves and wear while in contact with the damping member, and further improve the service life of the shock absorbing device.

[0010] Furthermore, the shock absorbing device also includes a vent, which is arranged on at least one of the multiple sleeves, and the vent is connected to the piston cavity. By providing the vent, the piston cavity can be connected to the outside world, so as to avoid the formation of positive and negative pressures during the reciprocating motion of the piston rod, which affects the normal movement of the piston rod. It is worth noting that the vent can be arranged on one of the multiple sleeves, or on multiple sleeves. As long as the position is reasonable, the vent can be considered to be arranged, so as to ensure that the pressure at each position of the piston cavity is balanced.

[0011] In a possible design, further, the number of the vents is N, and the N vents located on one sleeve are symmetrically distributed along the center line of the piston cavity, wherein N is an even number.

[0012] In this design, the number of vents is N, and the N vents on the same sleeve are symmetrically distributed along the center line of the piston cavity, and N is an even number. When the vents on the same sleeve are symmetrically distributed, the positive and negative pressures formed during the reciprocating motion of the piston rod in the sleeve can be discharged to the outside through the symmetrically distributed vents. The symmetrically distributed vents can keep the force of the sleeve balanced and avoid fatigue damage to the part of the sleeve adjacent to the vent that may be caused by the positive and negative pressures concentrated on a certain vent. Specifically, the number of sleeves is multiple, and at least one of the multiple sleeves has N symmetrically distributed vents. In other words, multiple sleeves can have vents that are an integer multiple of N, so that the safe use performance of each sleeve can be guaranteed.

[0013] In a possible design, further, the plurality of sleeves include a first sleeve and at least one second sleeve. One end of the first sleeve is used to connect to the device to be damped, and the other end of the first sleeve is provided with a first connecting portion. The end of the second sleeve close to the first sleeve in at least one second sleeve is provided with a second connecting portion, and the second sleeve is connected to the first sleeve by the cooperation of the second connecting portion and the first connecting portion.

[0014] In this design, the plurality of sleeves include a first sleeve and at least one second sleeve. Specifically, one end of the first sleeve is used to connect to the clothing processing device. For example, one end of the first sleeve can be fixedly mounted to the clothing processing device, or can be rotated relative to the position connected to the clothing processing device. The specific setting can be based on actual needs. By connecting the shock absorbing device to the clothing processing device, the relative movement of the piston rod can be hindered by the damping member during the operation of the clothing processing device, thereby achieving the purpose of reducing the vibration noise of the clothing processing device. Specifically, the other end of the first sleeve is provided with a first connecting portion, and at least one second sleeve includes a second sleeve close to the first sleeve. The end of the second sleeve is provided with a second connecting portion, and the first connecting portion is adapted to the second connecting portion, that is, the second sleeve can be connected to the first connecting portion of the first sleeve through the second connecting portion, thereby realizing a detachable connection between the first sleeve and the second sleeve.

[0015] In addition, the number of second sleeves can be selected as needed, that is, the number of detachably connected second sleeves can be selected according to the actual size of the entire shock absorbing device. When a sleeve among the multiple sleeves fails, the failed sleeve can be directly replaced. This can avoid the problem of needing to replace the entire sleeve when a failure occurs somewhere in the one-piece sleeve in the related art, thereby reducing the cost of use.

[0016] It should be noted that the damping element can be provided on the first sleeve and / or at least one second sleeve. Specifically, the damping element can be provided on each second sleeve of at least one second sleeve to enhance the friction force generated between the piston rod and the damping element during the movement of the piston rod, thereby improving the effect of reducing the vibration noise of the clothing processing device. In addition, the damping element can also be provided on at least two second sleeves of the plurality of second sleeves, so as to generate different friction resistances according to the vibration amplitude of the clothing processing device to reduce the vibration noise of the clothing processing device, and the specific setting can be based on actual needs.

[0017] It should also be noted that the clothing processing device includes a barrel body and a box body, wherein the device to be shock-absorbing can be a barrel body or a box body, that is, the first sleeve can be connected to the box body, and correspondingly, the piston rod is connected to the barrel body; the first sleeve can be connected to the barrel body, and correspondingly, the piston rod is connected to the box body, so that during the operation of the clothing processing device, the relative movement of the piston rod is hindered by the damping member, thereby achieving the purpose of reducing the vibration noise of the clothing processing device.

[0018] It is worth noting that the first connecting portion and the second connecting portion may be structures such as buckles and buckle grooves, and any structure that can achieve a detachable connection is applicable.

[0019] In a possible design, further, one of the first connection portion and the second connection portion includes an external thread, and the other of the first connection portion and the second connection portion includes an internal thread.

[0020] In this design, the first connection part and the second connection part are threadedly matched, so that the connection between the first sleeve and the second sleeve can be made more reliable. Since the first sleeve is connected to the device to be damped, the impact force borne at the connection between the first sleeve and the second sleeve is relatively large, so the first sleeve and the second sleeve are connected through a threaded structure, so that the contact area can be increased, and the connection reliability can be further improved. It is worth noting that the first connection part includes an external thread and the second connection part includes an internal thread, and the second sleeve is disposed outside the end of the first sleeve. Of course, the first connection part includes an internal thread and the second connection part includes an external thread. In this case, the first sleeve is disposed outside the end of the second sleeve.

[0021] It is worth noting that the first sleeve and the first connection part are an integrated structure. The second sleeve and the second connection part are an integrated structure. Specifically, the end of the first sleeve is cut to form an external thread (first connection part), and the end of the second sleeve is cut to form an internal thread. The thread structure is easy to process and has low cost.

[0022] In a possible design, further, the at least one damping member includes a first damping member, and the first damping member is arranged on a sleeve having an external thread.

[0023] In this design, at least one damping member includes a first damping member. If the first connection portion is an external thread, the first damping member is provided on the first sleeve corresponding to the external thread. Similarly, if the second connection portion is an external thread, the first damping member is provided on the second sleeve corresponding to the external thread. By providing the first damping member on the sleeve with an external thread, on the one hand, the installation position of the first damping member can be clearly identified through the external thread, ensuring accurate positioning and installation of the first damping member. On the other hand, the provision of the first damping member will not interfere with the installation of the internal thread and the external thread.

[0024] In a possible design, further, a third connection portion is provided at an end of at least one second sleeve far from the first sleeve. The plurality of sleeves further include a third sleeve, a fourth connection portion is provided at an end of the third sleeve close to the second sleeve, and the third sleeve is connected to the second sleeve by cooperating with the third connection portion through the fourth connection portion.

[0025] In this design, the multiple sleeves also include a third sleeve, that is, the sleeve structure in which the shock absorbing device cooperates with the piston rod is composed of a first sleeve, at least one second sleeve and a third sleeve. Specifically, a fourth connection portion is provided at one end of the third sleeve, and the fourth connection portion of the third sleeve is connected to the third connection portion of the last second sleeve of at least one second sleeve, so as to realize a detachable connection of the multiple sleeves. The piston rod is inserted into the multiple sleeves from the end of the other end of the third sleeve, and then the damping member hinders the relative movement of the piston rod in the multiple sleeves to achieve the effect of reducing the vibration noise of the clothing processing device.

[0026] It should be noted that the third sleeve is the tail of the multiple sleeves. Specifically, a protective device can be provided at the end of the third sleeve away from the second sleeve to prevent wear at the contact portion between the piston rod and the end of the third sleeve, thereby extending the service life of the multiple sleeves.

[0027] In a possible design, further, one of the third connection portion and the fourth connection portion is a hook, and the other of the third connection portion and the fourth connection portion is a slot.

[0028] In this design, the specific structure of the third connection part and the fourth connection part is defined. Specifically, one of the third connection part and the fourth connection part is a hook, and the other of the third connection part and the fourth connection part is a slot. In other words, a hook or a slot can be provided on the second sleeve, and a slot or a hook can be provided on the third sleeve. Specifically, if a slot is provided on the second sleeve and a hook is provided on the third sleeve, the slot is provided through the second sleeve. By providing a hook and a slot for matching connection, it is possible to achieve convenient installation and disassembly while ensuring the connection strength and connection reliability between multiple sleeves, thereby improving the stability of the shock absorbing device during operation and ensuring the shock absorbing effect of the clothing processing equipment.

[0029] Among them, it should be noted that the number of the slots and the hooks is a one-to-one correspondence, and the multiple slots are spaced apart along the circumferential direction of the second sleeve, and the multiple hooks correspond to the multiple slots one-to-one. By setting multiple hooks and multiple slots, the connection strength between the multiple sleeves can be further guaranteed, thereby further improving the operating stability of the shock absorbing device, ensuring the noise reduction effect of the clothing processing equipment, and improving the user experience. Among them, the number of slots should not be too large. If the number of slots is too large, the structural strength of the second sleeve will be reduced, thereby reducing the working stability of the shock absorbing device. In addition, the multiple slots can be distributed at equal intervals along the circumferential direction of the second sleeve, which can ensure that the connection positions of the multiple sleeves can be evenly stressed during the operation of the shock absorbing device, further improving the service life of the shock absorbing device. It should also be noted that the slots can be spaced apart along the circumferential direction of the second sleeve, and the positions of the hooks and the slots correspond to each other one-to-one, which can be set according to actual needs.

[0030] Specifically, the hook can be an integrated structure with the third sleeve. The integrated structure has good mechanical properties, can improve the overall structural strength of the third sleeve, and further ensure the connection strength and stability between the multiple sleeves.

[0031] In a possible design, the shock absorbing device further includes a first stop portion, and the first stop portion is arranged on a sleeve having a slot, and the hook can abut against the first stop portion after extending into the slot.

[0032] In this design, by providing the first stop portion, when the second sleeve and the third sleeve are assembled and the hook is inserted into the slot, the end of the hook can abut against the first stop portion. When the piston rod moves in the piston chamber, the first stop portion can limit the hook and the sleeve where the hook is located, thereby ensuring reliable connection performance between the second sleeve and the third sleeve connected by the slot and the hook during long-term use, thereby improving the service life of the shock absorbing device.

[0033] It is worth noting that the first stopper and the sleeve with the slot are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve, and further ensure the connection strength and stability between multiple sleeves.

[0034] Specifically, when the second sleeve is provided with a slot, the third sleeve is provided with a hook, and the first stopper is provided on the outer wall of the second sleeve corresponding to the slot, and the first stopper and the second sleeve are an integrated structure. It is worth noting that the first stopper can be an annular structure, and the first stopper can not only play a role in limiting the hook, but also can further strengthen the structural strength of the second sleeve, and further improve the service life of the shock absorbing device. Of course, the first stopper can also be provided on the second sleeve corresponding to the slot. If a plurality of slots are arranged on the second sleeve at intervals along the circumference of the sleeve, the first stopper corresponds to the slot and is arranged on the second sleeve at intervals along the circumference of the sleeve. Correspondingly, when the slot is provided on the third sleeve, the first stopper is provided on the third sleeve corresponding to the slot. At this time, corresponding to the slot, the second sleeve is provided with a hook that matches it.

[0035] In a possible design, the shock absorbing device further includes a second stop portion, which is provided on the sleeve with the hook, and after the hook extends into the slot, the end of the sleeve with the slot can abut against the second stop portion.

[0036] In this design, by providing a second stopper on the sleeve with the hook, when the second sleeve is matched with the third sleeve, after the hook is inserted into the slot, the end of the sleeve with the slot can abut against the second stopper. That is, in the movement direction of the piston rod, with the cooperation of the first stopper and the second stopper, a two-way limit is provided for the second sleeve and the third sleeve, thereby further improving the reliable connection performance between the second sleeve and the third sleeve and extending the service life of the shock absorbing device.

[0037] It is worth mentioning that the second stop portion and the sleeve with the hook are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve, and further ensure the connection strength and stability between multiple sleeves.

[0038] Specifically, when the second sleeve is provided with a slot, the third sleeve is provided with a hook, the second stopper is provided on the outer wall of the third sleeve, and the second stopper and the third sleeve are an integrated structure. It is worth noting that the second stopper can be an annular structure, and the second stopper can not only limit the second sleeve, but also further strengthen the structural strength of the second sleeve, thereby further improving the service life of the shock absorbing device.

[0039] In a possible design, further, the first stopper and the sleeve with the slot are an integrated structure. The second stopper and the sleeve with the hook are an integrated structure.

[0040] In this design, the card slot is provided on the second sleeve, and the card hook is provided on the third sleeve, so that the first stopper and the second sleeve are an integrated structure, and the second stopper and the third sleeve are an integrated structure. The first stopper and the second sleeve are specifically an integrated structure, because the mechanical properties of the integrated structure are good, and thus the connection strength between the first stopper and the second sleeve can be improved. In addition, the first stopper and the second sleeve can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the first stopper and the second sleeve as an integrated structure formed in one piece, the integrity of the shock absorbing device is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the shock absorbing device is more convenient and reliable.

[0041] Of course, the card slot can also be arranged on the third sleeve, and the card hook can be arranged on the second sleeve, then the first stopper and the third sleeve are an integrated structure, and the second stopper and the second sleeve are an integrated structure, which can be arranged according to actual needs.

[0042] In a possible design, further, the at least one damping member includes a second damping member, and the second damping member is arranged on the sleeve having the hook.

[0043] In this design, at least one damping member includes a second damping member, and the second damping member is arranged on a sleeve with a hook. When the hook is arranged on the third sleeve, by arranging the second damping member on the third sleeve, on the one hand, the installation position of the second damping member is clearly defined by the hook housing, ensuring the accurate positioning and installation of the second damping member, and on the other hand, the arrangement of the second damping member will not interfere with the assembly of the hook and the slot. It is worth noting that the free end of the hook extends in a direction away from the center line of the piston cavity, that is, the hook extends into the slot from the inside to the outside, that is, the wall surface of the hook facing the center line of the piston cavity can form the installation position of the second damping member.

[0044] Specifically, the first damping member is installed in the first sleeve, the second damping member is installed in the third sleeve, the first sleeve and the second sleeve are connected by a threaded structure, so that the contact area between the first sleeve and the second sleeve can be increased, and the second sleeve and the third sleeve are connected by a hook and a groove. The detachable connection of multiple sleeves can realize the installation of two damping members in multiple sleeves, and at the same time, vents are also provided on the first sleeve and the second sleeve, so as to prevent the positive and negative pressures formed by the piston rod during the reciprocating motion process.

[0045] It is worth noting that the assembly process of the shock absorbing device is as follows: 1) install the first damping member into the first sleeve; 2) install the second damping member into the third sleeve; 3) finally rotate the first sleeve to connect to the first end of the second sleeve, and clamp the third sleeve into the second end of the second sleeve, thereby completing a shock absorbing device equipped with two damping members.

[0046] It is worth noting that the number of damping members in the present application can be at least one, which can be increased according to the actual demand for damping members, and the structural adaptability of the corresponding sleeves can be adjusted. Vents are provided at the first sleeve and the second sleeve, so as to prevent positive and negative pressures formed by the piston rod during the reciprocating motion.

[0047] Specifically, during the movement of the shock absorbing device, the middle part of the sleeve structure formed by the multiple sleeves (the connection between the first sleeve and the second sleeve) will be subjected to a strong bending force. Therefore, in the present application, the first sleeve and the second sleeve are connected by a threaded structure, so as to enhance the overall structure of the shock absorbing device. It is worth noting that the connection between the second sleeve and the third sleeve is diversified, and can be connected by a hook and slot, or a threaded structure, etc. Of course, the first damping member can also be arranged in the second sleeve, so that the second sleeve can be rotated and connected to the first sleeve.

[0048] In a possible design, further, the inner wall surface of the damping element protrudes from the inner wall surface of the sleeve.

[0049] In this design, the damping member is an annular elastic member, and a corresponding mounting position is provided on the sleeve corresponding to the damping member, and the damping member is embedded in the mounting position. The sleeve has a first inner wall surface adjacent to the damping member, and the inner wall surface of the damping member protrudes from the first inner wall surface of the sleeve, so that when the piston rod extends into the piston cavity, the piston rod can contact the damping member, and will not contact the inner wall surfaces of multiple sleeves and cause wear, which can further improve the service life of the shock absorbing device. Specifically, the inner diameter of the damping member is smaller than the inner diameter of the piston cavity.

[0050] In a possible design, further, the other end of the first sleeve is provided with an external thread, the end of the second sleeve close to the first sleeve in at least one second sleeve is provided with an internal thread, and the first sleeve and the second sleeve are threadedly connected. The shock absorbing device also includes a limiting portion, which is provided on the outer wall of the first sleeve, and the end of the second sleeve can abut against the limiting portion.

[0051] In this design, one end of the first sleeve can be connected to the device to be damped, and the other end of the first sleeve is provided with an external thread. At least one second sleeve includes a second sleeve close to the first sleeve, and the end of the second sleeve is provided with an internal thread. The first sleeve and the second sleeve are threadedly connected, so that the position that bears a strong bending force in the sleeve structure formed by the multiple sleeves can be threadedly connected, thereby enhancing the overall structure of the damping device.

[0052] Furthermore, by providing a limiting portion on the outer wall of the first sleeve, when the first sleeve and the second sleeve are assembled, the end of the second sleeve can abut against the limiting portion, and when the piston rod reciprocates in the piston chamber, the limiting portion can limit the second sleeve, thereby ensuring reliable connection performance between the first sleeve and the second sleeve connected by the threaded structure during long-term use, thereby improving the service life of the shock absorbing device.

[0053] It is worth noting that the limiting portion and the first sleeve are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve, and further ensure the connection strength and stability between the multiple sleeves.

[0054] Furthermore, the limiting portion may be an annular structure, which can not only limit the second sleeve, but also further enhance the structural strength of the first sleeve, thereby extending the service life of the shock absorbing device. Of course, the limiting portion may also be a plurality of limiting protrusions, which are arranged on the first sleeve at intervals along the circumference of the piston cavity, thereby achieving a multi-directional limiting effect on the second sleeve, and also reducing material costs.

[0055] In a possible design, further, a portion of the second sleeve is bent to form an assembly groove, a groove side wall of the assembly groove is provided with an internal thread, and a portion of the first sleeve extends into the assembly groove and abuts against the groove bottom of the assembly groove.

[0056] In this design, a portion of the second sleeve is bent to form an assembly groove, and an internal thread is provided on the side wall of the assembly groove. A portion of the first sleeve extends into the assembly groove and abuts against the bottom of the assembly groove. In the movement direction of the piston rod, with the cooperation of the limiting portion and the assembly groove, a two-way limit is provided for the first sleeve and the second sleeve, thereby further improving the reliable connection performance between the first sleeve and the second sleeve and extending the service life of the shock absorbing device.

[0057] According to a second aspect of the present invention, there is provided a clothes processing device, comprising the shock absorbing device provided by any of the above designs.

[0058] The clothes processing device provided by the present invention includes the shock absorbing device provided by any of the above designs, and therefore has all the beneficial effects of the shock absorbing device, which will not be described in detail here.

[0059] It is worth noting that the clothing processing device is a washing machine.

[0085] Embodiment 1

[0086] According to a first aspect of the present invention, a shock absorbing device 100 is provided. Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the shock absorbing device 100 includes a plurality of sleeves 110, a piston rod 120, at least one damping member 130 and a vent 140, wherein each sleeve 110 of the plurality of sleeves 110 is sequentially connected to form a piston chamber 110a. At least a portion of the piston rod 120 extends into the piston chamber 110a and can move relative to the sleeve 110. At least one damping member 130 is disposed on the inner wall of at least one sleeve 110 of the plurality of sleeves 110, and the piston rod 120 can contact the at least one damping member 130. The vent 140 is disposed on at least one sleeve 110 of the plurality of sleeves 110 and is communicated with the piston chamber 110a.

[0087] The shock absorbing device 100 provided in the embodiment of the present invention comprises a plurality of sleeves 110, a piston rod 120, at least one damping member 130 and a vent 140. Specifically, each sleeve 110 is detachably connected in sequence, which is convenient for installation and disassembly. In addition, when a sleeve 110 among the plurality of sleeves 110 of the shock absorbing device 100 fails, it is only necessary to directly replace the failed sleeve 110, which can avoid the problem that the entire sleeve 110 needs to be replaced when a failure occurs somewhere in the sleeve 110 formed in one piece in the related art, thereby reducing the use cost. The number of damping members 130 is at least one, and specifically, the damping member 130 is arranged on the inner wall of at least one sleeve 110 among the plurality of sleeves 110, that is, the number of damping members 130 can be one or more. The plurality of damping members 130 can be arranged on one sleeve 110 in a concentrated manner, or can be arranged on a plurality of sleeves 110 in a dispersed manner, and the specific arrangement of the damping members 130 can be designed according to actual needs. Further, the plurality of sleeves 110 can form a piston cavity 110a, at least a portion of the piston rod 120 can extend into the piston cavity 110a, and the piston rod 120 can move relative to the plurality of sleeves 110. In the process of the piston rod 120 moving in and out of the plurality of sleeves 110, the piston rod 120 can contact with at least one damping member 130 and generate friction, thereby hindering the relative movement of the piston rod 120, thereby reducing the vibration generated by the clothing processing device having the shock absorbing device 100 during operation, thereby achieving the purpose of reducing the vibration noise of the clothing processing device. By configuring a sleeve 110 as a structure in which a plurality of sleeves 110 are sequentially detachably connected, the damping member 130 can be arranged at multiple positions of the sleeve 110 to achieve a better noise reduction effect, and the plurality of sleeves 110 can be detachably connected, and the damping member 130 can also be easily repaired and replaced.

[0088] In addition, by arranging damping elements 130 at various positions of the plurality of sleeves 110, the piston rod 120 can contact the damping elements 130 at various positions during the movement. When a large vibration occurs during the operation of the clothing processing equipment, or when the clothing processing equipment resonates, the amplitude of the shock absorbing device 100 is longer, that is, the movement stroke of the piston rod 120 is larger, that is, the number of damping elements 130 contacted by the piston rod 120 is larger, and the friction force generated between the plurality of damping elements 130 and the piston rod 120 is larger, so that the vibration amplitude of the clothing processing equipment can be effectively controlled, thereby reducing the vibration noise of the clothing processing equipment. When the vibration occurring during the operation of the clothing processing device is small, or when the clothing processing device does not resonate, the amplitude of the shock absorbing device 100 is small, that is, the movement stroke of the piston rod 120 is short, that is, the number of damping elements 130 contacted by the piston rod 120 is small, for example, only one damping element 130 is contacted, and the friction resistance generated between the small number of damping elements 130 and the piston rod 120 can achieve the effect of controlling the vibration noise of the clothing processing device. That is to say, by arranging the damping elements 130 at various positions of the plurality of sleeves 110, different friction resistances can be generated according to the vibration amplitude of the clothing processing device to reduce the vibration noise of the clothing processing device.

[0089] It should be noted that the damping member 130 may be an elastic member, which may not only generate friction resistance when in contact with the piston rod 120, but also buffer the movement of the piston rod 120 in and out of the multiple sleeves 110. Specifically, when the laundry processing device is working and vibrates, the piston rod 120 moves in and out of the multiple sleeves 110. By setting the damping member 130 as an elastic member, when the amplitude of the vibration of the laundry processing device is large, the impact force of the piston rod 120 on the multiple sleeves 110 can be reduced, and the effect of reducing vibration noise of the shock absorbing device 100 can be further improved. In addition, the damping member 130 has a through hole, and the multiple sleeves 110 form a piston cavity 110a. The diameter of the through hole may be slightly smaller than the diameter of the piston cavity 110a, so that the piston rod 120 can avoid contact with the inner wall of the multiple sleeves 110 and wear while in contact with the damping member 130, and further improve the service life of the shock absorbing device 100.

[0090] Furthermore, the shock absorbing device 100 further includes a vent 140, which is disposed on at least one of the multiple sleeves 110, and the vent 140 is in communication with the piston chamber 110a. By providing the vent 140, the piston chamber 110a can be in communication with the outside world, thereby preventing the piston rod 120 from forming positive and negative pressures during the reciprocating motion, thereby affecting the normal motion of the piston rod 120. It is worth noting that the vent 140 can be disposed on one of the multiple sleeves 110, or on multiple sleeves 110. As long as the position is reasonable, the vent 140 can be considered to be disposed, thereby ensuring that the pressure at each position of the piston chamber 110a is balanced.

[0091] In a possible design, further, as Figure 2 , Figure 4 and Figure 8 As shown, the number of the vents 140 is N, and the N vents 140 located on one sleeve 110 are symmetrically distributed along the center line of the piston chamber 110a, wherein N is an even number.

[0092] In this embodiment, the number of vents 140 is N, and the N vents 140 on the same sleeve 110 are symmetrically distributed along the center line of the piston chamber 110a, and N is an even number. When the vents 140 on the same sleeve 110 are symmetrically distributed, the positive and negative pressures formed during the reciprocating motion of the piston rod 120 in the sleeve 110 can be discharged to the outside through the symmetrically distributed vents 140. The symmetrically distributed vents 140 can keep the force of the sleeve 110 balanced, and avoid fatigue damage to the part of the sleeve 110 adjacent to the vent 140 caused by the positive and negative pressures concentrated on a certain vent 140. Specifically, the number of sleeves 110 is multiple, and at least one sleeve 110 among the multiple sleeves 110 has N symmetrically distributed vents 140. In other words, multiple sleeves 110 can have an integer multiple of N vents 140, so that the safe use performance of each sleeve 110 can be guaranteed.

[0093] Embodiment 2

[0094] Based on the above-mentioned embodiment, this embodiment describes the specific structure of the sleeve 110. Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the plurality of sleeves 110 include a first sleeve 111 and at least one second sleeve 112. One end of the first sleeve 111 is used to connect with the device to be damped, and the other end of the first sleeve 111 is provided with a first connecting portion 111a. The end of the second sleeve 112 close to the first sleeve 111 in the at least one second sleeve 112 is provided with a second connecting portion 112a, and the second sleeve 112 is connected to the first sleeve 111 through the cooperation of the second connecting portion 112a and the first connecting portion 111a.

[0095] In this embodiment, the plurality of sleeves 110 include a first sleeve 111 and at least one second sleeve 112. Specifically, one end of the first sleeve 111 is used to connect to the clothing processing device. For example, one end of the first sleeve 111 can be fixedly mounted to the clothing processing device, or can be rotated relative to the position connected to the clothing processing device, which can be set according to actual needs. By connecting the shock absorbing device 100 to the clothing processing device, the relative movement of the piston rod 120 can be hindered by the damping member 130 during the operation of the clothing processing device, thereby achieving the purpose of reducing the vibration noise of the clothing processing device. Specifically, a first connecting portion 111a is provided at the other end of the first sleeve 111, and at least one second sleeve 112 includes a second sleeve 112 close to the first sleeve 111, and a second connecting portion 112a is provided at the end of the second sleeve 112. The first connecting portion 111a is adapted to the second connecting portion 112a, that is, the second sleeve 112 can be connected to the first connecting portion 111a of the first sleeve 111 through the second connecting portion 112a, thereby realizing a detachable connection between the first sleeve 111 and the second sleeve 112.

[0096] In addition, the number of second sleeves 112 can be selected as needed, that is, the number of detachably connected second sleeves 112 can be selected according to the actual size of the entire shock absorbing device 100. When a sleeve 110 among the multiple sleeves 110 fails, the failed sleeve 110 can be directly replaced. This can avoid the problem of the need to replace the entire sleeve 110 when a failure occurs somewhere in the one-piece sleeve 110 in the related art, thereby reducing the cost of use.

[0097] It should be noted that the damping member 130 can be provided on the first sleeve 111 and / or at least one second sleeve 112. Specifically, the damping member 130 can be provided on each second sleeve 112 of at least one second sleeve 112 to enhance the friction generated between the piston rod 120 and the damping member 130 during the movement of the piston rod 120, thereby improving the effect of reducing the vibration noise of the laundry processing device. In addition, the damping member 130 can also be provided on at least two second sleeves 112 of the plurality of second sleeves 112, so as to generate different friction resistances according to the vibration amplitude of the laundry processing device to reduce the vibration noise of the laundry processing device, and can be provided specifically according to actual needs.

[0098] It should also be noted that the clothing processing device includes a barrel body and a box body, wherein the device to be shock-absorbing can be a barrel body or a box body, that is, the first sleeve 111 can be connected to the box body, and accordingly, the piston rod 120 is connected to the barrel body; the first sleeve 111 can be connected to the barrel body, and accordingly, the piston rod 120 is connected to the box body, so that during the operation of the clothing processing device, the damping member 130 hinders the relative movement of the piston rod 120, thereby achieving the purpose of reducing the vibration noise of the clothing processing device.

[0099] It is worth noting that the first connection portion 111a and the second connection portion 112a may be structures such as buckles and buckle grooves, and any structure that can achieve a detachable connection is applicable.

[0100] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, one of the first connection portion 111a and the second connection portion 112a includes an external thread, and the other of the first connection portion 111a and the second connection portion 112a includes an internal thread.

[0101] In this embodiment, the first connection portion 111a and the second connection portion 112a are threadedly matched, so that the connection between the first sleeve 111 and the second sleeve 112 can be made more reliable. Since the first sleeve 111 is connected to the device to be damped, the impact force borne at the connection between the first sleeve 111 and the second sleeve 112 is relatively large, so that the first sleeve 111 and the second sleeve 112 are connected through a threaded structure, so that the contact area can be increased, and the connection reliability can be further improved. It is worth noting that the first connection portion 111a includes an external thread, and the second connection portion 112a includes an internal thread, and the second sleeve 112 is disposed on the end of the first sleeve 111. Of course, the first connection portion 111a may also include an internal thread, and the second connection portion 112a may include an external thread. In this case, the first sleeve 111 is disposed on the end of the second sleeve 112.

[0102] It is worth noting that the first sleeve 111 and the first connecting portion 111a are an integrated structure. The second sleeve 112 and the second connecting portion 112a are an integrated structure. Specifically, the end of the first sleeve 111 is cut to form an external thread (the first connecting portion 111a), and the end of the second sleeve 112 is cut to form an internal thread. The thread structure is easy to process and has low cost.

[0103] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the at least one damping member 130 includes a first damping member 131 , and the first damping member 131 is disposed on the sleeve 110 having an external thread.

[0104] In this embodiment, at least one damping member 130 includes a first damping member 131. If the first connection portion 111a is an external thread, the first damping member 131 is provided on the first sleeve 111 corresponding to the external thread. Similarly, if the second connection portion 112a is an external thread, the first damping member 131 is provided on the second sleeve 112 corresponding to the external thread. By providing the first damping member 131 on the sleeve 110 having an external thread, on the one hand, the installation position of the first damping member 131 can be clearly identified through the external thread, ensuring the accurate positioning and installation of the first damping member 131. On the other hand, the provision of the first damping member 131 will not interfere with the installation of the internal thread and the external thread.

[0105] Furthermore, if Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a third connection portion 112b is provided at the end of at least one second sleeve 112 away from the first sleeve 111. The plurality of sleeves 110 further include a third sleeve 113, and a fourth connection portion 113a is provided at the end of the third sleeve 113 close to the second sleeve 112. The third sleeve 113 is connected to the second sleeve 112 by matching the fourth connection portion 113a with the third connection portion 112b.

[0106] In this embodiment, the plurality of sleeves 110 further include a third sleeve 113, that is, the sleeve 110 structure in which the shock absorbing device 100 cooperates with the piston rod 120 is composed of a first sleeve 111, at least one second sleeve 112 and a third sleeve 113. Specifically, a fourth connecting portion 113a is provided at one end of the third sleeve 113, and the fourth connecting portion 113a of the third sleeve 113 is connected to the third connecting portion 112b of the last second sleeve 112 in the at least one second sleeve 112, so as to realize a detachable connection of the plurality of sleeves 110. The piston rod 120 is inserted into the plurality of sleeves 110 from the end of the other end of the third sleeve 113, and then the damping member 130 hinders the relative movement of the piston rod 120 in the plurality of sleeves 110, so as to achieve the effect of reducing the vibration noise of the laundry processing device.

[0107] It should be noted that the third sleeve 113 is the tail end of the multiple sleeves 110. Specifically, a protective device can be provided at the end of the third sleeve 113 away from the second sleeve 112 to prevent wear at the contact portion between the piston rod 120 and the end of the third sleeve 113, thereby extending the service life of the multiple sleeves 110.

[0108] Further, one of the third connection portion 112b and the fourth connection portion 113a is a hook, and the other of the third connection portion 112b and the fourth connection portion 113a is a slot.

[0109] In this embodiment, the specific structure of the third connection part 112b and the fourth connection part 113a is defined. Specifically, one of the third connection part 112b and the fourth connection part 113a is a hook, and the other of the third connection part 112b and the fourth connection part 113a is a slot. In other words, a hook or a slot can be provided on the second sleeve 112, and a slot or a hook can be provided on the third sleeve 113. Specifically, if a slot is provided on the second sleeve 112 and a hook is provided on the third sleeve 113, the slot is provided through the second sleeve 112. By providing a hook and a slot for matching connection, it is possible to achieve convenient installation and disassembly while ensuring the connection strength and connection reliability between the multiple sleeves 110, thereby improving the stability of the shock absorbing device 100 during operation and ensuring the shock absorbing effect of the clothing processing equipment.

[0110] It should be noted that the number of the slots and the hooks is a one-to-one correspondence, and the multiple slots are spaced apart along the circumferential direction of the second sleeve 112, and the multiple hooks correspond to the multiple slots one-to-one. By setting the multiple hooks and the multiple slots, the connection strength between the multiple sleeves 110 can be further guaranteed, thereby further improving the operation stability of the shock absorbing device 100, ensuring the noise reduction effect of the clothing processing device, and improving the user experience. The number of slots should not be too large. If the number of slots is too large, the structural strength of the second sleeve 112 will be reduced, thereby reducing the working stability of the shock absorbing device 100. In addition, the multiple slots can be distributed at equal intervals along the circumferential direction of the second sleeve 112, which can ensure that the connection positions of the multiple sleeves 110 can be evenly stressed during the operation of the shock absorbing device 100, further improving the service life of the shock absorbing device 100. It should also be noted that the slots can be spaced apart along the circumferential direction of the second sleeve 112, and the positions of the hooks and the slots correspond to each other, which can be set according to actual needs.

[0111] Specifically, the hook can be an integrated structure with the third sleeve 113 . The integrated structure has good mechanical properties, can improve the overall structural strength of the third sleeve 113 , and further ensure the connection strength and stability between the multiple sleeves 110 .

[0112] It is conceivable that one of the third connection portion 112b and the fourth connection portion 113a includes an external thread, and the other of the third connection portion 112b and the fourth connection portion 113a includes a thread.

[0113] In this embodiment, the third connection part 112b and the fourth connection part 113a can also be threadedly matched, so that the connection between the third connection part 112b and the fourth connection part 113a can be made more reliable. If the impact force borne by the connection between the second sleeve 112 and the third sleeve 113 is large, the second sleeve 112 and the third sleeve 113 are connected by a threaded structure, so that the contact area can be increased and the connection reliability can be further improved. It is worth noting that the third connection part 112b includes an external thread and the fourth connection part 113a includes an internal thread, and the third sleeve 113 is disposed on the end of the second sleeve 112. Of course, the third connection part 112b includes an internal thread and the fourth connection part 113a includes an external thread. At this time, the second sleeve 112 is disposed on the end of the third sleeve 113.

[0114] Embodiment 3

[0115] On the basis of the above-mentioned embodiment, this embodiment describes the limiting structure between the sleeves 110, and further, as shown in FIG. Figure 8 As shown, the shock absorbing device 100 further includes a first stopper 150 , which is disposed on the sleeve 110 having a slot, and the hook can abut against the first stopper 150 after extending into the slot.

[0116] In this embodiment, the first stop portion 150 is provided so that when the second sleeve 112 and the third sleeve 113 are assembled and the hook is inserted into the slot, the end of the hook can abut against the first stop portion 150. When the piston rod 120 moves in the piston chamber 110a, the first stop portion 150 can limit the hook and the sleeve 110 where the hook is located, thereby ensuring the reliable connection performance between the second sleeve 112 and the third sleeve 113 connected by the slot and the hook during long-term use, thereby improving the service life of the shock absorbing device 100.

[0117] It is worth noting that the first stopper 150 and the sleeve 110 with the slot are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve 110, and further ensure the connection strength and stability between the multiple sleeves 110.

[0118] Specifically, when the second sleeve 112 is provided with a slot, the third sleeve 113 is provided with a hook, and the first stopper 150 is provided on the outer wall of the second sleeve 112 corresponding to the slot, and the first stopper 150 and the second sleeve 112 are an integrated structure. It is worth noting that the first stopper 150 can be an annular structure, and the first stopper 150 can not only play a role in limiting the hook, but also can further strengthen the structural strength of the second sleeve 112, and further improve the service life of the shock absorbing device 100. Of course, the first stopper 150 can also be provided on the second sleeve 112 corresponding to the slot. If a plurality of slots are arranged on the second sleeve 112 at intervals along the circumference of the sleeve 110, the first stopper 150 corresponds to the slot and is arranged on the second sleeve 112 at intervals along the circumference of the sleeve 110. Correspondingly, when the slot is provided on the third sleeve 113 , the first stopper 150 is provided on the third sleeve 113 corresponding to the slot. At this time, corresponding to the slot, a hook cooperating with the slot is provided on the second sleeve 112 .

[0119] Furthermore, if Figure 8 As shown, the shock absorbing device 100 further includes a second stopper 160 , which is disposed on the sleeve 110 with the hook. After the hook extends into the slot, the end of the sleeve 110 with the slot can abut against the second stopper 160 .

[0120] In this embodiment, the second stopper 160 is provided on the sleeve 110 with the hook, so that when the second sleeve 112 cooperates with the third sleeve 113, after the hook extends into the slot, the end of the sleeve 110 with the slot can abut against the second stopper 160. That is, in the movement direction of the piston rod 120, with the cooperation of the first stopper 150 and the second stopper 160, a two-way limit is provided for the second sleeve 112 and the third sleeve 113, so that the reliable connection performance between the second sleeve 112 and the third sleeve 113 can be further improved, and the service life of the shock absorbing device 100 can be extended.

[0121] It is worth mentioning that the second stop portion 160 and the sleeve 110 with the hook are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve 110, and further ensure the connection strength and stability between the multiple sleeves 110.

[0122] Specifically, when the second sleeve 112 is provided with a slot, the third sleeve 113 is provided with a hook, and the second stopper 160 is provided on the outer wall of the third sleeve 113, and the second stopper 160 and the third sleeve 113 are an integrated structure. It is worth noting that the second stopper 160 can be an annular structure, and the second stopper 160 can not only limit the second sleeve 112, but also further strengthen the structural strength of the second sleeve 112, thereby further improving the service life of the shock absorbing device 100.

[0123] Furthermore, the first stopper 150 and the sleeve 110 with the slot are an integrated structure. The second stopper 160 and the sleeve 110 with the hook are an integrated structure.

[0124] In this embodiment, the card slot is provided on the second sleeve 112, and the card hook is provided on the third sleeve 113, so the first stopper 150 and the second sleeve 112 are an integrated structure, and the second stopper 160 and the third sleeve 113 are an integrated structure. The first stopper 150 and the second sleeve 112 are specifically an integrated structure, because the mechanical properties of the integrated structure are good, so the connection strength between the first stopper 150 and the second sleeve 112 can be improved. In addition, the first stopper 150 and the second sleeve 112 can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the first stopper 150 and the second sleeve 112 as an integrated structure, the integrity of the shock absorbing device 100 is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the shock absorbing device 100 is more convenient and reliable.

[0125] Of course, the card slot can also be set on the third sleeve 113, and the card hook can be set on the second sleeve 112, so that the first stopper 150 and the third sleeve 113 are an integrated structure, and the second stopper 160 and the second sleeve 112 are an integrated structure, which can be set according to actual needs.

[0126] Furthermore, if Figure 2 As shown, the at least one damping member 130 includes a second damping member 132 , and the second damping member 132 is disposed on the sleeve 110 having the hook.

[0127] In this embodiment, at least one damping member 130 includes a second damping member 132, and the second damping member 132 is arranged on the sleeve 110 with a hook. When the hook is arranged on the third sleeve 113, by arranging the second damping member 132 on the third sleeve 113, on the one hand, the installation position of the second damping member 132 is clearly defined through the hook housing, ensuring the accurate positioning and installation of the second damping member 132, and on the other hand, the arrangement of the second damping member 132 will not interfere with the assembly of the hook and the slot. It is worth noting that the free end of the hook extends in a direction away from the center line of the piston chamber 110a, that is, the hook extends into the slot from the inside to the outside, that is, the wall of the hook facing the center line of the piston chamber 110a can form the installation position of the second damping member 132.

[0128] Specifically, the first damping member 131 is installed in the first sleeve 111, the second damping member 132 is installed in the third sleeve 113, the first sleeve 111 and the second sleeve 112 are connected by a threaded structure, so that the contact area between the first sleeve 111 and the second sleeve 112 can be increased, and the second sleeve 112 and the third sleeve 113 are connected by a hook and a groove. The multiple sleeves 110 are detachably connected, so that two damping members 130 can be installed in multiple sleeves 110. At the same time, the first sleeve 111 and the second sleeve 112 are also provided with vents 140, so as to prevent the positive and negative pressures formed by the piston rod 120 during the reciprocating motion process.

[0129] It is worth noting that the assembly process of the shock absorbing device 100 is as follows:

[0130] 1) Install the first damping member 131 into the first sleeve 111;

[0131] 2) Install the second damping member 132 into the third sleeve 113;

[0132] 3) Finally, the first sleeve 111 is rotated to connect to the first end of the second sleeve 112, and the third sleeve 113 is inserted into the second end of the second sleeve 112, so that a shock absorbing device 100 equipped with two damping members 130 can be completed.

[0133] It is worth noting that the number of the damping member 130 in the present application can be at least one, and can be increased according to the actual demand for the damping member 130, and the structural adaptability of the corresponding sleeve 110 can be adjusted. The first sleeve 111 and the second sleeve 112 are provided with vents 140, so as to prevent the positive and negative pressures formed by the piston rod 120 during the reciprocating motion process.

[0134] Specifically, during the movement of the shock absorbing device 100, the middle part of the sleeve 110 structure formed by the multiple sleeves 110 (the connection between the first sleeve 111 and the second sleeve 112) will be subjected to a strong bending force. Therefore, in the present application, the first sleeve 111 and the second sleeve 112 are connected by a threaded structure, so as to enhance the overall structure of the shock absorbing device 100. It is worth noting that the connection between the second sleeve 112 and the third sleeve 113 is diversified, and can be connected by a hook and slot, or a threaded structure, etc. Of course, the first damping member 131 can also be arranged in the second sleeve 112, so that the second sleeve 112 can be rotated and connected to the first sleeve 111.

[0135] Furthermore, the inner wall surface of the damping member 130 protrudes from the inner wall surface of the sleeve 110 .

[0136] In this embodiment, the damping member 130 is an annular elastic member, and a corresponding mounting position is provided on the sleeve 110 corresponding to the damping member 130, and the damping member 130 is embedded in the mounting position. The sleeve 110 has a first inner wall surface adjacent to the damping member 130, and the inner wall surface of the damping member 130 protrudes from the first inner wall surface of the sleeve 110, so that when the piston rod 120 extends into the piston cavity 110a, the piston rod 120 can contact the damping member 130, and will not contact with the inner wall surfaces of multiple sleeves 110 to cause wear, which can further improve the service life of the shock absorbing device 100. Specifically, the inner diameter of the damping member 130 is smaller than the inner diameter of the piston cavity 110a.

[0141] It is worth noting that the limiting portion 170 and the first sleeve 111 are an integrated structure, and the integrated structure has good mechanical properties, can improve the overall structural strength of the sleeve 110, and further ensure the connection strength and stability between the multiple sleeves 110.

[0142] Furthermore, the limiting portion 170 may be an annular structure, which can not only limit the second sleeve 112, but also further enhance the structural strength of the first sleeve 111, thereby extending the service life of the shock absorbing device 100. Of course, the limiting portion 170 may also be a plurality of limiting protrusions, which are arranged on the first sleeve 111 at intervals along the circumference of the piston cavity 110a, thereby achieving a multi-directional limiting effect on the second sleeve 112, and also reducing material costs.

[0145] Embodiment 5

[0146] According to a second aspect of the present invention, there is provided a clothes processing device, comprising the shock absorbing device 100 provided by any of the above designs.

[0147] The clothes processing device provided by the present invention includes the shock absorbing device 100 provided by any of the above designs, and therefore has all the beneficial effects of the shock absorbing device 100, which will not be described in detail here.

[0148] It is worth noting that the clothing processing device is a washing machine.

[0149] Specifically, the shock absorbing device 100 includes a plurality of sleeves 110, a piston rod 120, at least one damping member 130 and a vent 140, wherein each sleeve 110 of the plurality of sleeves 110 is sequentially connected to form a piston chamber 110a. At least a portion of the piston rod 120 extends into the piston chamber 110a and can move relative to the sleeve 110. At least one damping member 130 is disposed on the inner wall of at least one sleeve 110 of the plurality of sleeves 110, and the piston rod 120 can contact the at least one damping member 130. The vent 140 is disposed on at least one sleeve 110 of the plurality of sleeves 110 and communicates with the piston chamber 110a.

[0150] The shock absorbing device 100 provided in the embodiment of the present invention comprises a plurality of sleeves 110, a piston rod 120, at least one damping member 130 and a vent 140. Specifically, each sleeve 110 is detachably connected in sequence, which is convenient for installation and disassembly. In addition, when a sleeve 110 among the plurality of sleeves 110 of the shock absorbing device 100 fails, it is only necessary to directly replace the failed sleeve 110, which can avoid the problem that when a certain part of the sleeve 110 formed in one piece in the related art fails, the entire sleeve 110 needs to be replaced, thereby reducing the use cost. The number of damping members 130 is at least one, and specifically, the damping member 130 is arranged on the inner wall of at least one sleeve 110 among the plurality of sleeves 110, that is, the number of damping members 130 can be one or more. The plurality of damping members 130 can be arranged on one sleeve 110 in a concentrated manner, or can be arranged on a plurality of sleeves 110 in a dispersed manner, and the specific arrangement of the damping members 130 can be designed according to actual needs. Further, the plurality of sleeves 110 can form a piston cavity 110a, at least a portion of the piston rod 120 can extend into the piston cavity 110a, and the piston rod 120 can move relative to the plurality of sleeves 110. In the process of the piston rod 120 moving in and out of the plurality of sleeves 110, the piston rod 120 can contact with at least one damping member 130 and generate friction, thereby hindering the relative movement of the piston rod 120, thereby reducing the vibration generated by the clothing processing device having the shock absorbing device 100 during operation, thereby achieving the purpose of reducing the vibration noise of the clothing processing device. By configuring a sleeve 110 as a structure in which a plurality of sleeves 110 are sequentially detachably connected, the damping member 130 can be arranged at multiple positions of the sleeve 110 to achieve a better noise reduction effect, and the plurality of sleeves 110 can be detachably connected, and the damping member 130 can also be easily repaired and replaced.

[0151] In addition, by arranging damping elements 130 at various positions of the plurality of sleeves 110, the piston rod 120 can contact the damping elements 130 at various positions during the movement. When a large vibration occurs during the operation of the clothing processing equipment, or when the clothing processing equipment resonates, the amplitude of the shock absorbing device 100 is longer, that is, the movement stroke of the piston rod 120 is larger, that is, the number of damping elements 130 contacted by the piston rod 120 is larger, and the friction force generated between the plurality of damping elements 130 and the piston rod 120 is larger, so that the vibration amplitude of the clothing processing equipment can be effectively controlled, thereby reducing the vibration noise of the clothing processing equipment. When the vibration occurring during the operation of the clothing processing device is small, or when the clothing processing device does not resonate, the amplitude of the shock absorbing device 100 is small, that is, the movement stroke of the piston rod 120 is short, that is, the number of damping elements 130 contacted by the piston rod 120 is small, for example, only one damping element 130 is contacted, and the friction resistance generated between the small number of damping elements 130 and the piston rod 120 can achieve the effect of controlling the vibration noise of the clothing processing device. That is to say, by arranging the damping elements 130 at various positions of the plurality of sleeves 110, different friction resistances can be generated according to the vibration amplitude of the clothing processing device to reduce the vibration noise of the clothing processing device.

[0152] It should be noted that the damping member 130 may be an elastic member, which may not only generate friction resistance when in contact with the piston rod 120, but also buffer the movement of the piston rod 120 in and out of the multiple sleeves 110. Specifically, when the laundry processing device is working and vibrates, the piston rod 120 moves in and out of the multiple sleeves 110. By setting the damping member 130 as an elastic member, when the amplitude of the vibration of the laundry processing device is large, the impact force of the piston rod 120 on the multiple sleeves 110 can be reduced, and the effect of reducing vibration noise of the shock absorbing device 100 can be further improved. In addition, the damping member 130 has a through hole, and the multiple sleeves 110 form a piston cavity 110a. The diameter of the through hole may be slightly smaller than the diameter of the piston cavity 110a, so that the piston rod 120 can avoid contact with the inner wall of the multiple sleeves 110 and wear while in contact with the damping member 130, and further improve the service life of the shock absorbing device 100.

[0153] Furthermore, the shock absorbing device 100 further includes a vent 140, which is disposed on at least one of the multiple sleeves 110, and the vent 140 is in communication with the piston chamber 110a. By providing the vent 140, the piston chamber 110a can be in communication with the outside world, thereby preventing the piston rod 120 from forming positive and negative pressures during the reciprocating motion, thereby affecting the normal motion of the piston rod 120. It is worth noting that the vent 140 can be disposed on one of the multiple sleeves 110, or on multiple sleeves 110. As long as the position is reasonable, the vent 140 can be considered to be disposed, thereby ensuring that the pressure at each position of the piston chamber 110a is balanced.
