Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular relates to a washing machine. Background Art

[0002] When washing clothes in an existing washing machine, the water in the washing tub module is located in the inner tub and also between the inner tub and the outer tub. After long-term use, the dirt between the inner tub and the outer tub will breed a large number of bacteria. Although the emergence of hole-free inner tub washing machines has improved the hygiene and safety of washing machines to a certain extent, cross-infection between different clothes still makes many users have concerns about the safety of washing machines. In addition, in the dehydration scheme of existing washing machines, it is usually adopted to let the inner tub and the impeller rotate synchronously and at high speed, so that the water on the laundry is separated from the laundry under the action of centrifugal force and discharged from the gap between the inner tub and the outer tub. This dehydration method is prone to generate large vibration and noise, and is easy to cause large damage to the laundry.

[0003] In order to avoid cross infection between different clothes and reduce the vibration and noise generated when the washing machine is dehydrating, the manufacturer has launched a washing machine with a replaceable inner barrel and negative pressure dehydration. Specifically, the inner barrel is detachably installed in the shell of the washing machine, the inner barrel wall of the inner barrel is deformable and has a certain deformation margin, and the washing machine is provided with a negative pressure component connected to the inner barrel, which sucks water and air in the inner barrel, causing the inner barrel to shrink and squeeze the clothes to achieve dehydration.

[0004] However, the inner barrel is generally connected to the accommodating cavity in the shell by magnetic attraction, and the magnetic attraction method is mainly a vertical up and down attraction method. At the same time, since it is necessary to set a washing power unit such as a impeller at the center of the bottom of the inner barrel, the suction port is generally set at a position deviating from the axis of the inner barrel. During use of the washing machine with this installation method, under the action of eccentric negative pressure and the tension of the inner barrel, it is easy to separate the magnetic attraction structure between the inner barrel and the accommodating cavity, resulting in air leakage, which seriously affects the dehydration effect of the washing machine.

[0005] Therefore, designing a washing machine that can prevent the connection structure between the inner barrel and the accommodating cavity from separating and leaking during negative pressure dehydration has become a technical problem that needs to be solved urgently by technical personnel in this field.

[0006] In view of this, the present invention is proposed. Summary of the invention

By arranging a plug-in structure between the bottom of an inner barrel and a accommodating cavity, the plug-in structure can be used to offset the tilting pulling force caused by eccentric negative pressure and contraction of the inner barrel wall during negative pressure dehydration, thereby improving the installation stability of the inner barrel and solving the problem that in existing washing machines with replaceable inner barrels and capable of negative pressure dehydration, the connection structure between the inner barrel and the accommodating cavity is easily separated during negative pressure dehydration.

[0054] Embodiment 1

[0055] like Figures 1 to 6 As shown, in an embodiment of the present invention, a washing machine is introduced. Specifically, the washing machine is a washing machine with a replaceable inner barrel 3.

[0056] By arranging the inner tub 3 to be detachably installed in the washing machine body 1, a washing machine can be equipped with multiple inner tubs 3, which facilitates the replacement of the inner tubs 3. During use, one person can use one tub or multiple tubs, and the number of inner tubs 3 can be configured according to the use requirements to achieve classified washing, which can prevent cross infection when washing different clothes in the washing machine. At the same time, there is no need to configure multiple washing machines, which saves costs.

[0057] In this embodiment, a receiving cavity for receiving the inner barrel 3 is provided in the body 1 of the washing machine. The receiving cavity may be an outer barrel 4 installed in the body 1 or may be directly integrated in the body 1 of the washing machine.

[0058] The inner barrel 3 is detachably installed in the accommodating cavity, and the inner barrel 3 is connected to the accommodating cavity by magnetic attraction.

[0059] Specifically, the magnetic connection structure is arranged between the inner barrel bottom and the accommodating cavity of the inner barrel 3. A magnet is arranged on one of the inner barrel bottom and the bottom wall of the accommodating cavity, and a magnetic member is arranged on the other of the inner barrel bottom and the bottom wall of the accommodating cavity. The arrangement position of the magnetic member corresponds to the magnet. When the inner barrel 3 is installed, the magnet and the magnetic member are attracted to achieve the fixation between the inner barrel 3 and the machine body 1 to ensure the sealing. When the user needs to replace the inner barrel 3, it is necessary to overcome the attraction between the magnetic member and the magnet, take the inner barrel 3 out of the machine body 1, and after taking it out, install another inner barrel 3.

[0060] In the existing washing machines with replaceable inner barrel 3 and capable of negative pressure dehydration, since a washing power unit such as a pulsator 5 needs to be arranged at the center of the bottom of the inner barrel, the suction port is generally arranged at a position deviating from the axis of the inner barrel 3. The magnetic attraction between the inner barrel 3 and the accommodating cavity is mainly a vertical up-and-down attraction. During the use of the washing machine under this attraction mode, under the action of the eccentric negative pressure and the pulling force of the inner barrel 3, it is easy to separate the magnetic attraction structure between the inner barrel 3 and the accommodating cavity, thereby causing air leakage, which seriously affects the dehydration effect of the washing machine.

[0061] To solve the above problem, in this embodiment of the present invention, a plug-in structure is provided between the inner barrel 3 and the accommodating cavity, and the plug-in structure extends along the installation direction of the inner barrel. When the inner barrel is installed, the plug-in structure between the bottom of the inner barrel and the accommodating cavity is engaged.

[0062] Specifically, a protruding structure 3025 is provided on one of the bottom of the inner barrel and the bottom of the accommodating cavity, and a recessed structure 401 is provided on the other of the accommodating cavity and the bottom of the inner barrel. Both the protruding structure 3025 and the recessed structure 401 extend along the installation direction of the inner barrel 3, and the recessed structure 401 is adapted to the shape of the protruding structure 3025. During the installation of the inner barrel 3, the protruding structure 3025 is inserted into the recessed structure 401.

[0063] By arranging a protruding structure 3025 and a recessed structure 401 that are plugged into and fit with each other between the bottom of the inner barrel and the accommodating cavity, the protruding structure 3025 and the recessed structure 401 can be used to limit each other during the negative pressure dehydration process to offset the tilting pulling force caused by the eccentric negative pressure and the contraction of the inner barrel wall 310, thereby preventing the inner barrel bottom from tilting, reducing the burden of the magnetic attraction structure between the inner barrel 3 and the accommodating cavity, and improving the installation stability of the inner barrel 3, thereby ensuring the sealing of the inner barrel 3 and ensuring a stable dehydration effect.

[0064] Preferably, in this embodiment, in order to reduce the thickness of the inner barrel bottom, the protruding structure 3025 is arranged on the inner barrel bottom, and the recessed structure 401 is arranged on the bottom wall of the accommodating cavity, and the protruding structure 3025 and the recessed structure 401 both extend along the axial extension direction of the inner barrel 3. Specifically, the protruding structure 3025 extends axially downward from the lower end surface of the inner barrel bottom, and the recessed structure 401 extends from the bottom wall of the accommodating cavity in a direction away from the inner barrel 3. The internal shape of the recessed structure 401 is the same as that of the protruding structure 3025. When the inner barrel 3 is installed, the protruding structure 3025 is embedded in the recessed structure 401 to achieve positioning.

[0065] In this embodiment, the protruding structure 3025 is annular and coaxial with the inner barrel 3, and extends along the axial direction of the inner barrel 3. Preferably, the protruding structure 3025 is arranged on the bottom of the inner barrel, and the outer diameter of the protruding structure 3025 is smaller than the diameter of the bottom of the inner barrel.

[0066] In order to improve the installation stability between the inner barrel 3 and the accommodating cavity while ensuring that the user can replace the inner barrel 3 with less effort, in this embodiment, the magnetic connection structure can be arranged between the protruding structure 3025 and the recessed structure 401.

[0067] Specifically, one of the magnet and the magnetic member can be arranged on the inner wall of the recessed structure 401, and the other of the magnet and the magnetic member can be arranged on the outer wall of the protruding structure 3025, and the magnet and the magnetic member can be attracted to each other accordingly.

[0068] Preferably, in this embodiment, the magnet is arranged on the inner wall of the recessed structure 401, and the magnetic member is arranged on the protruding structure 3025 at a position corresponding to the magnet.

[0069] Preferably, in this embodiment, the protruding structure 3025 can be entirely configured as a magnetic member.

[0070] In some possible embodiments, the recessed structure 401 is disposed through the bottom of the outer barrel 4 and includes two oppositely disposed groove walls. The magnets are disposed on the groove walls and include a plurality of magnets spaced apart along the circumferential direction.

[0071] Preferably, the magnets are evenly arranged along the circumferential direction on the inner groove wall and the outer groove wall of the recessed structure 401 .

[0072] Further preferably, the magnets on the inner circumferential groove wall and the magnets on the outer circumferential groove wall are arranged alternately in the circumferential direction.

[0073] In some other possible embodiments, the recessed structure 401 includes a groove bottom and two oppositely disposed groove walls.

[0074] In this embodiment, the magnet includes a first magnet arranged on the bottom of the groove of the recessed structure 401, and the first magnet is used to engage with the bottom of the protruding structure 3025; and / or the magnet includes a second magnet arranged on the groove wall of the recessed structure 401, and the second magnet is used to engage with the inner periphery and / or outer periphery of the protruding structure 3025.

[0075] Preferably, in this embodiment, the first magnet is embedded in the groove bottom of the recessed structure 401 , and the second magnet is embedded in the groove wall of the recessed structure 401 , and the first magnet and the second magnet are arranged at intervals along the circumference of the recessed structure 401 .

[0076] Preferably, in this embodiment, second magnets are respectively arranged on the inner groove wall and the outer groove wall of the recessed structure 401, and the second magnets on the inner groove wall and the second magnets on the outer groove wall are arranged alternately.

[0077] In some other possible embodiments, the magnet may further include a third magnet, which is embedded in the bottom of the accommodating cavity at the outer periphery of the recessed portion, and a magnetic member corresponding to the third magnet is further arranged on the bottom of the inner barrel.

[0078] Through the above arrangement, it is possible to ensure that the inner barrel 3 is installed stably while not increasing or only increasing to a small extent the force required by the user to take out the inner barrel 3, thereby improving the user experience.

[0079] In this embodiment, the protruding structure 3025 is a stainless steel structure, and the magnet is injection molded in the recessed structure 401 of the outer barrel 4 .

[0080] In this embodiment, the inner barrel wall 310 of the inner barrel 3 is made of soft material. Preferably, the inner barrel wall 310 is made of fumed silica gel.

[0081] In this embodiment, the length of a single-section single-side path is calculated based on the theoretical ultimate stretching path of the inner barrel wall 310, and the actual inner barrel wall 310 molding material structure is optimized in combination with the actual elongation characteristics of the gas phase silica gel and the actual dehydration effect.

[0082] If the inner barrel wall 310 is too long, the material of the inner barrel wall 310 will accumulate on the clothes during negative pressure dehydration, and the squeezing force on the clothes will be weakened, affecting the dehydration effect; if the inner barrel wall 310 is too short, it will stretch itself and then pull the bottom of the inner barrel. If the negative pressure suction force is greater than the combined suction force of the magnet, the bottom of the inner barrel will be detached from the bottom of the accommodating cavity.

[0083] Preferably, in this embodiment, the negative pressure capacity and the properties of silica gel are combined, and the range of -65Kpa to -75Kpa is selected, and the length of the inner barrel wall 310 is designed to be 80%-90% of the limit path length.

[0084] Specifically, a nesting portion 312 folded and extended toward the inner barrel 3 is provided at the top of the inner barrel wall 310 , and the nesting portion 312 provides a margin for deformation of the inner barrel 3 .

[0085] In this embodiment, the inner barrel 3 includes an inner barrel wall 310 , a barrel mouth positioning member 303 connected to the upper end of the inner barrel wall 310 , and a barrel bottom connecting member 302 arranged at the lower end of the inner barrel wall 310 .

[0086] In this embodiment, the inner barrel wall 310 includes an inner barrel wall 310 main body, and the nesting portion 312 is arranged on the top of the inner barrel wall 310 main body, one end of the nesting portion 312 is connected to the top of the inner barrel wall 310 main body, and the other end of the nesting portion 312 extends to the outside of the inner barrel wall 310 main body and is connected to the barrel mouth positioning piece 303.

[0087] In this embodiment, a pulsator 5 for stirring clothes and water flow is arranged at the inner center of the barrel bottom connecting member 302. The pulsator 5 is spherical or cylindrical. The limit path of the inner barrel wall 310 is as follows: Figure 3 As shown, the inner side of the inner barrel wall 310 is in contact with the outer peripheral wall of the impeller 5 .

[0088] In this embodiment, the washing machine further comprises a door body 2 , which is buckled on the top of the body 1 and sealably matched with the inner barrel opening 300 .

[0089] Preferably, in the present embodiment, a blocking portion adapted to the shape of the inner barrel opening 300 is provided at the bottom of the door body 2 , and the blocking portion is inserted into the inner barrel opening 300 and has an interference fit with the inner barrel opening 300 .

[0090] In this embodiment, a sealing lip 314 extending toward the inside of the inner barrel opening 300 is provided on the inner periphery of the inner barrel opening 300 , and the sealing lip 314 is sandwiched between the inner barrel opening 300 and the blocking portion.

[0091] Preferably, the diameter of the inner barrel mouth 300 is the same as the diameter of the sealing part, and the inner barrel mouth 300 is sealed with the sealing part through the sealing lip 314.

[0092] The sealing lip 314 extends from the inner periphery of the inner barrel opening 300 in a direction close to the axis of the inner barrel 3, and the sealing lip 314 is inclined toward the bottom of the inner barrel along the extension direction close to the axis of the inner barrel 3.

[0093] Preferably, in this embodiment, the thickness of the middle portion of the sealing lip 314 is smaller than the thickness of the inner circumference and the outer circumference thereof, so that the sealing lip 314 can be bent more easily and better sealing can be ensured.

[0094] In this embodiment, a mounting portion 307 for mounting the barrel mouth positioning member 303 is provided at the top of the inner barrel wall 310. The mounting portion 307 is bent and extended from the top of the inner barrel wall 310 toward the outer periphery of the inner barrel 3. The sealing lip 314 is provided on the inner periphery of the inner barrel wall 310 and connected at the connection between the inner barrel wall 310 and the mounting portion 307.

[0095] Embodiment 2

[0096] like Figures 6 to 10 As shown, in an embodiment of the present invention, an inner barrel is introduced, which includes an inner barrel body, wherein the inner barrel body includes an inner barrel wall 310 and an inner barrel bottom, and an inner barrel opening 300 is provided at one end of the inner barrel wall 310 away from the inner barrel bottom.

[0097] In this embodiment, the inner barrel is applied to a washing machine with a negative pressure dehydration function. The inner barrel wall 310 of the inner barrel is made of soft materials such as rubber. During the dehydration stage, the washing machine applies negative pressure to the inner barrel to extract the water and air in the inner barrel. At this time, the inner barrel wall 310 contracts inward, and the inner wall of the inner barrel squeezes the clothes in the inner barrel to squeeze out the washing water in the clothes, thereby achieving the effect of squeezing dehydration. Thus, the vibration and noise generated by the washing machine during dehydration can be reduced, and at the same time, the wear of the washing clothes during the dehydration process of the washing machine can be reduced, thereby improving the user experience.

[0098] In this embodiment, in order to ensure the smooth performance of negative pressure dehydration, it is necessary to ensure that the inner barrel contracts smoothly on a fixed basis. For this purpose, the inner barrel developed by the manufacturer is provided with transverse pleats on the inner barrel wall 310, and the pleats provide a margin for the contraction of the inner barrel wall 310. Although this type of inner barrel can smoothly achieve the effect of squeezing and dehydration, the deformation of the pleats is small during the negative pressure dehydration process of this inner barrel, and the negative pressure value required to reach the contracted state is high, so the clothes cannot be fully squeezed and the dehydration effect is poor.

[0099] like Figure 6 and Figure 7 As shown, in order to improve the dehydration effect of the negative pressure dehydration washing machine, a new type of inner barrel is provided in the embodiment of the present invention, wherein the inner barrel wall 310 of the inner barrel is made of soft material, and a nesting portion 312 is provided on the inner barrel wall 310, and the nesting portion 312 provides a margin for the contraction of the inner barrel wall 310. The nesting portion 312 includes a first portion 3121 and a second portion 3122 extending into the inner barrel wall 310 and folded with each other, which is easier to stretch than the pleated type, and has a larger amount of stretchable deformation, and the resistance generated by the inner barrel wall 310 itself during the contraction process is smaller, so that a more sufficient squeezing effect can be achieved, and the dehydration effect is improved.

[0100] Specifically, in this embodiment, the inner barrel wall 310 includes an inner barrel wall body 3101 and a vertical section 3102 arranged above the inner barrel wall body 3101, and a nesting portion 312 is arranged between the inner barrel wall body 3101 and the vertical section 3102, and the nesting portion 312 is used to connect the inner barrel wall body 3101 and the vertical section 3102 as a whole to form a complete inner barrel wall 310.

[0101] The inner barrel wall body 3101 is in the shape of a cylinder with openings at the top and bottom, the vertical section 3102 is coaxially arranged with the inner barrel wall body 3101, the vertical section 3102 is arranged above the inner barrel wall body 3101, and the nesting portion 312 is connected between the upper end of the inner barrel wall body 3101 and the lower end of the vertical section 3102. Preferably, in this embodiment, the outer diameter of the vertical section 3102 is the same as the outer diameter of the inner barrel wall body 3101, and the nesting portion 312 is nested between the inner barrel wall body 3101 and / or the vertical section 3102, so as to ensure the integrity of the inner barrel wall 310.

[0102] In this embodiment, the nesting portion 312 is coaxially arranged with the inner barrel wall body 3101 and the vertical section 3102. The nesting portion 312 includes a first portion 3121 extending from the top of the inner barrel wall body 3101 to the inside of the inner barrel wall body 3101, and a second portion 3122 extending from the end of the first portion 3121 to the outside of the inner barrel wall body 3101 and connected to the lower end of the vertical section 3102.

[0103] By setting the inner barrel wall 310 including the inner barrel wall main body 3101 and the vertical section 3102, and setting the inner barrel wall main body 3101 and the vertical section 3102 to be connected by the nesting part 312, the nesting part 312 provides a margin for the deformation of the inner barrel, and when the negative pressure is drawn into the inner barrel, the nesting part 312 can stretch to provide sufficient shrinkage margin for the inner barrel wall 310 and reduce the deformation resistance of the inner barrel. At the same time, during the stretching process, the nesting part 312 can make the top of the inner barrel wall main body 3101 shrink downward, so that the inner wall of the inner barrel can squeeze the clothes more fully, thereby improving the dehydration effect.

[0104] In this embodiment, the first part 3121 of the nesting portion 312 is bent and extended from the top of the inner barrel wall body 3101 toward the direction close to the inner wall of the inner barrel wall body 3101, and the second part 3122 of the nesting portion 312 is bent and extended from the lower end of the first part 3121 toward the inner periphery of the first part 3121 and upward, and the second part 3122 of the nesting portion 312 at least partially extends above the inner barrel wall body 3101.

[0105] Preferably, the nesting portion 312 includes a plurality of groups of first parts 3121 and second parts 3122 that are arranged continuously or at intervals.

[0106] Specifically, the nested portion includes multiple layers extending from the inner barrel wall to the inner barrel, and the second part of the lower nested portion is connected to the first part of the adjacent upper nested portion.

[0107] Alternatively, a vertically extending inner barrel wall is provided between two adjacent nested portions, the end of the first portion of the upper nested portion is connected to the upper end of the vertically extending inner barrel wall, and the end of the second portion of the lower nested portion is connected to the lower end of the vertically extending inner barrel wall.

[0108] In this embodiment, multiple layers of vertical sections 3102 are coaxially arranged above the inner barrel wall body 3101. The inner barrel wall body 3101 and the bottommost vertical section 3102 are connected via a nested portion 312, and adjacent vertical sections 3102 are sequentially connected via multiple layers of nested portions 312 to form a complete inner barrel wall.

[0109] Preferably, in this embodiment, the extension lengths of the first part and the second part of the multi-layer nested portion are the same or different.

[0110] Preferably, the multiple layers of vertical segments 3102 have the same diameter and the same or different axial extension lengths.

[0111] Further preferably, in this embodiment, the axial length of the uppermost vertical segment 3102 is greater than the axial extension lengths of the remaining vertical segments. The upper end of the uppermost vertical segment 3102 forms the inner barrel opening.

[0112] In this embodiment, only one layer of nesting parts is provided on the inner barrel wall as an example for description.

[0113] Specifically, the first part 3121 of the nested portion 312 includes a first curved section 31211 extending from the top of the inner barrel wall body 3101 to the inner circumference, a second curved section 31212 extending from the end of the first curved section 31211 to the inner wall of the inner barrel wall body 3101, and a third curved section 31213 extending from the end of the second curved section 31212 to the inner wall of the inner barrel wall body 3101, and the curvatures of the first curved section 31211, the second curved section 31212 and the third curved section 31213 decrease successively.

[0114] The inner diameter of the first portion 3121 of the nesting portion 312 first gradually decreases and then gradually increases in a direction from top to bottom.

[0115] Thus, the nesting portion 312 smoothly transitions between the first bending section 31211 and the upper end of the inner barrel wall body 3101. The first part 3121 of the nesting portion 312 first extends toward the inner periphery of the inner barrel wall body 3101 from top to bottom, and then extends toward the direction close to the inner wall of the inner barrel wall body 3101. When the inner barrel shrinks, the nesting portion 312 can be more easily stretched, thereby reducing the shrinkage resistance of the inner barrel wall body 3101.

[0116] Preferably, in this embodiment, the curvature of the third curved section 31213 is zero.

[0117] Preferably, in this embodiment, the second part 3122 of the nesting portion 312 includes a fourth bent section 31221 which bends upward from the lower end of the third bent section 31213 toward the inner periphery of the first part 3121 of the nesting portion 312, a fifth bent section 31222 which extends upward from the end of the fourth bent section 31221, and a sixth bent section 31223 which bends upward and toward the outer periphery from the end of the fifth bent section 31222, and the upper end of the sixth bent section 31223 is integrally connected to the lower end of the vertical section 3102.

[0119] The curvature of one end of the sixth curved segment 31223 close to the fifth curved segment 31222 is the same as the curvature of the second curved segment 31212 , and the curvature of one end of the sixth curved segment 31223 away from the fifth curved segment 31222 gradually decreases.

[0120] Preferably, in this embodiment, the curvature of the end of the sixth curved section 31223 away from the fifth curved section 31222 is zero, and is connected to the lower end of the vertical section 3102 .

[0121] Through the above arrangement, the extension direction of the nesting portion 312 can be more conducive to the deformation of the inner barrel wall body 3101 to shrink the top downward, thereby improving the adaptability of the nesting portion 312 to the shrinkage deformation of the inner barrel wall 310, reducing the shrinkage resistance of the inner barrel wall 310, and improving the squeezing effect of the inner wall of the inner barrel on the clothes.

[0122] Preferably, in the present embodiment, the first part 3121 and the second part 3122 of the nesting part 312 are spaced apart from each other, thereby avoiding interference between the first part 3121 and the second part 3122 of the nesting part 312, and improving the smoothness of the contraction and rebound of the inner barrel.

[0123] In this embodiment, the inner barrel wall body 3101, the nesting portion 312, and the vertical section 3102 are an integrally formed structure.

In this embodiment, the lower end of the nesting portion 312 extends to a position corresponding to the first contraction portion 3131.

[0126] In this embodiment, by providing the contraction portion 313, the internal integrity of the inner barrel wall 310 can be improved, and the clothes in the washing machine can be prevented from entering the gap between the nesting portion 312 and the inner wall of the inner barrel wall body 3101, thereby ensuring the washing effect of the clothes. In addition, the provision of the contraction portion 313 is also beneficial for guiding the contraction action of the inner barrel wall 310, thereby improving the squeezing effect on the clothes in the inner barrel.

[0127] Preferably, in this embodiment, the inner diameter of the second contraction portion 3132 is greater than or equal to the inner diameter of the nesting portion 312 .

[0128] In this embodiment, a fold portion 309 is provided between the lower end of the contraction portion 313 and the inner barrel wall body 3101 below the contraction portion 313, and the fold portion 309 includes at least one fold protruding radially toward the inside of the inner barrel wall body 3101, and / or at least protruding radially toward the outside of the inner barrel wall body 3101.

[0129] By setting a pleated portion 309 at the bottom of the inner barrel wall body 3101, the inner barrel wall body 3101 can be smoothly contracted inwardly. The pleated portion 309 can provide a margin for the contraction of the inner barrel wall body 3101, and at the same time, can provide guidance for the folding and contraction of the inner barrel wall 310, further improving the dehydration effect of the washing machine.

[0130] Preferably, in this embodiment, the inner diameter of the pleated portion 309 is the same as the inner diameter of the second contraction portion 3132 , and the outer diameter of the pleated portion 309 is the same as the outer diameter of the inner barrel wall body 3101 .

Specifically, the folded portion 309 first bends and extends from the lower end of the second contraction portion 3132 in a direction away from the axis of the inner barrel wall 310, then bends and extends downward in a direction close to the axis of the inner barrel wall 310, and finally bends and extends downward in a direction away from the axis of the inner barrel wall 310, and is connected to the inner barrel wall body 3101.

[0132] Of course, the specific number of folds provided in the fold portion 309 may be greater, which is not specifically limited here.
