Description

Technical Field

[0001] This invention relates to a wall-mounted washing machine in the field of household appliance technology, specifically, to a wall-mounted washing machine with a self-cleaning inner drum; and more particularly to a wall-mounted washing machine with linked inner and outer drum doors. Background Technology

[0002] Most washing machines are currently installed on the floor. However, due to limited living space, especially in small apartments with tiny bathrooms, it can feel cramped even for two people to stand in, let alone fit a floor-standing washing machine. A wall-mounted washing machine can solve this problem. Its relatively small size saves space and greatly satisfies users' laundry needs.

[0003] However, in existing wall-mounted washing machines, the washing water flows crosswise between the inner and outer drums, causing dirt to accumulate between them after prolonged use, affecting the washing effect. In particular, the smaller size and limited internal space of wall-mounted washing machines make it easier for residual water to accumulate, leading to bacterial growth between the inner and outer drums due to residual water and detergent, which in turn affects the washing effect.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a wall-mounted washing machine that seals the opening of the inner drum to achieve a self-cleaning effect for the inner drum. Furthermore, this invention also aims to provide a wall-mounted washing machine that achieves a linkage between the inner drum door and the door body.

[0006] To achieve the above-mentioned objectives, the specific structural solution adopted in this application is as follows:

[0007] This invention provides a wall-mounted washing machine, comprising: an outer drum for fixing to a wall surface; an inner drum rotatably installed inside the outer drum; a door that can open and close the opening of the outer drum and is installed on the outer drum; and an inner drum cover that can rotate relative to the outer drum is installed on the side of the door facing the outer drum. When the door closes the opening of the outer drum, the inner drum cover correspondingly closes the opening of the inner drum and can rotate around an axis together with the inner drum, so that after the door is closed, the inner drum cover correspondingly closes the opening of the inner drum, and the inner drum forms a sealed water container.

[0008] Furthermore, a non-contact magnetic levitation bearing is installed on the door body, and the rotating shaft of the inner cylinder cover is coaxially inserted into the non-contact magnetic levitation bearing, which is used to install the inner cylinder cover on the door body in a way that allows it to rotate around the shaft.

[0009] Furthermore, an annular mounting base is installed on the door body. Multiple silicon steel sheets are arranged radially and at an annular interval within the annular mounting base. Each silicon steel sheet is coiled around a coil. The center of the inner cylinder cover is provided with a shaft made of magnetic material, which protrudes and extends axially to one side of the door body. The extended end of the shaft is inserted into the inner circumference of the annular mounting base. The outer circumference of the extended end of the shaft is smaller than the inner radial dimension of the annular mounting base. This is used to generate electromagnetic driving force after the coil is energized to drive the shaft to a position coaxial with the annular mounting base, maintaining a certain distance between the shaft and the inner circumference of the annular mounting base, so that the shaft is in a suspended state.

[0010] Furthermore, the extended end of the shaft is provided with an annular limiting groove, and the inner circumference of the mounting base is provided with multiple buckles that protrude radially toward the center. The radial dimension of the annular surface formed by the inner circumference of each buckle is smaller than the outer circumference of the annular limiting groove and larger than the inner circumference of the annular limiting groove, so as to ensure that at least some of the buckles extend into the annular limiting groove.

[0011] Furthermore, the width of the annular limiting groove in the axial direction of the shaft is greater than the size of the part of the buckle that extends into the mounting groove, so as to ensure that when the shaft is in a suspended state after being subjected to the electromagnetic force of the energized coil, a floating gap is maintained between the shaft and the buckle.

[0012] Furthermore, the shaft is an independent component. The first end of the shaft is fixedly connected to the inner cylinder cover and can rotate around the shaft together with the inner cylinder cover. The second end is inserted into the annular mounting seat of the door body and is driven by an energized electromagnetic coil to be in a state where it can rotate freely around the shaft. Preferably, the first end of the shaft has multiple grooves, and the inner cylinder cover has multiple protrusions that extend into the grooves one to one.

[0013] Furthermore, the shaft is entirely made of magnetic material, and the shaft has a structure that is symmetrically distributed relative to the axis; or, a portion of the shaft is made of magnetic material, and the portion made of magnetic material is symmetrically distributed relative to the axis of the shaft; preferably, at least the second end of the shaft is made of magnetic material.

[0014] Furthermore, the outer cylinder is provided with a first locking structure that locks or unlocks the door; the inner cylinder is provided with a second locking structure that locks or unlocks the inner cylinder cover, which is used to drive the inner cylinder cover and the inner cylinder to rotate together.

[0015] Furthermore, a sealing structure is provided at the junction of the inner cylinder cover and the inner cylinder opening, and the sealing structure is installed at the inner cylinder cover and / or the inner cylinder opening.

[0016] Furthermore, the outer casing of the outer cylinder is provided with an outer shell, which is detachably connected to the outer cylinder via a snap-fit ​​structure; the door is installed on the outer shell and / or the outer cylinder and can be rotated outward to open and close.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0018] With the above-described design, an openable and closable inner drum cover is installed at the opening of the wall-mounted washing machine. This allows for controlled sealing of the inner drum opening, ensuring that the inner drum forms a sealed water container during washing. This prevents water from flowing between the inner and outer drums, achieving a self-cleaning effect for the inner drum. Simultaneously, the door can cover the inner drum cover, which rotates with the inner drum, effectively preventing contact during washing. Furthermore, the linked opening and closing mechanism between the inner drum cover and the door allows users to control the simultaneous opening and closing of the inner drum cover with a single operation of the door.

[0019] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a wall-mounted washing machine, which includes,

[0033] The outer cylinder 2 is fixed to the mounting wall surface by mounting screws that pass through the base feet provided at the bottom of the outer cylinder 19;

[0034] The inner cylinder 3 is rotatably installed inside the outer cylinder 2;

[0035] An openable and closable inner cylinder cover 6 is installed at the inner cylinder opening 17 so that the inner cylinder 3 can form a sealed water container after the inner cylinder cover 6 closes the inner cylinder opening 17.

[0036] With the above settings, an openable and closable inner drum cover is provided for the inner drum opening of the wall-mounted washing machine, so as to achieve the effect of controllable sealing of the inner drum opening of the wall-mounted washing machine. This ensures that the inner drum can form a sealed water container during the washing operation, avoiding cross-flow of washing water between the inner and outer drums, thus achieving the technical effect of no-cleaning of the inner drum.

[0037] like Figure 1As shown, in this embodiment, the inner drum cover 6 is installed at the inner drum opening 17 and can be flipped outward to open and close; the inner drum wall is provided with a drain outlet 16 that communicates with the outside, and a centrifugal valve 15 is installed at the drain outlet 16. The centrifugal valve 15 closes the drain outlet 16 when the washing machine is washing, and opens the drain outlet 16 when the washing machine is spinning and / or draining.

[0038] In this embodiment, the centrifugal valve 15 can be any existing valve body structure that controls the opening or closing of the drain outlet 16 by the centrifugal force of the inner cylinder 3; for example:

[0039] like Figure 1 As shown, the centrifugal valve 15 includes a mounting base, on which a support rod rotatable about an axis is provided. One end of the support rod is provided with a counterweight, and the other end is hinged to a valve core that can move radially along the inner cylinder to open and close the drain port accordingly. A spring is connected between the valve core and the mounting base to drive the valve core to reset and close the drain port accordingly. When the inner cylinder speed reaches a set value, the counterweight can be moved radially outward along the inner cylinder by centrifugal force, which pries the valve core through the support rod to overcome the spring force and move it inward towards the inner cylinder, thereby opening the drain port. When the inner cylinder speed is lower than the set value or when it is stationary, the counterweight is not subjected to centrifugal force, or the centrifugal force it receives cannot overcome the spring force, and the valve core remains in the initial position and closes the drain port accordingly.

[0040] By installing a centrifugal valve at the drain outlet on the inner drum wall, the drain outlet can be sealed by the centrifugal valve during washing or rinsing, thus achieving the effect of not having a normally open hole in the inner drum and forming a sealed water container during washing or rinsing.

[0041] like Figure 1 As shown, in this embodiment, the inner cylinder wall is an irregularly shaped cylinder with a large diameter in the middle and a gradually narrowing diameter towards the inner cylinder opening 17 and the inner cylinder bottom 18. The drain outlet 16 is located at the point of maximum diameter in the middle, so that the water in the inner cylinder 3 is drawn towards the point of maximum diameter in the middle by the centrifugal force generated when the inner cylinder 3 rotates, thereby increasing the drainage rate and reducing drainage residue. Preferably, the middle part of the inner cylinder wall is a straight cylinder section 22 with an equal diameter. The front and rear ends of the inner cylinder wall are a front conical cylinder section 21 and a rear conical cylinder section 23, respectively. The two ends of the straight cylinder section 22 are connected to the large openings of the front conical cylinder section 21 and the rear conical cylinder section 23, respectively. The small opening of the front conical cylinder section 21 forms the inner cylinder opening 17, and the small opening of the rear conical cylinder section 23 is closed to form the inner cylinder bottom 18. The straight cylinder section 22 is provided with a drain outlet 16 that communicates with the outside. The drain outlet 16 is provided with a centrifugal valve 15 that is controlled by the rotation speed of the inner cylinder 3.

[0042] like Figure 1As shown, in this embodiment, to prevent clothing from contacting the centrifugal valve 15, a lifting rib 14 is provided on the inner drum wall. The lifting rib 14 is hollow inside, and the centrifugal valve 15 is located in the hollow cavity inside the lifting rib 14. The inner cavity of the lifting rib 14 has an opening towards the inner drum wall, which closes the inner cavity after the lifting rib 14 is inverted onto the inner drum wall. A perforated notch is provided at the junction of the lifting rib 14 and the inner drum wall to allow washing water in the inner drum 3 to flow into the inner cavity of the lifting rib 14 through the perforated notch. At the same time, a drain outlet 16 is provided on the inner drum wall covered by the inverted lifting rib 14, so that water in the inner drum 3 can flow into the inner cavity of the lifting rib 14 through the perforated notch and then flow out through the open drain outlet 16. Thus, the centrifugal valve 15 is shielded by the lifting rib 14, preventing the centrifugal valve structure from contacting the clothing in the inner drum 3.

[0043] By implementing the above settings, the wall-mounted washing machine integrates a self-cleaning inner drum, preventing the washing water from flowing cross-flowing between the inner and outer drums. This improves the washing effect of the wall-mounted washing machine and avoids secondary contamination of clothes due to cross-flowing water after washing.

[0044] Example 2

[0045] like Figure 1 and Figure 2 As shown, this embodiment provides a wall-mounted washing machine, which includes an outer drum 2 with its axis extending horizontally. The bottom 19 of the outer drum is provided with a rearward protrusion, which forms a foot 9. The protruding end face of the foot 9 is flush with and in contact with the mounting wall. The foot 9 is provided with a mounting hole for mounting bolts to pass through, so as to fix the outer drum 2 to the mounting wall.

[0046] In this embodiment, there is a gap between the protruding end of the base 9 and the rear side of the outer cylinder bottom 19 facing the mounting wall, which is used to maintain the installation gap between the outer cylinder bottom 19 and the mounting wall.

[0047] The above settings ensure a gap between the outer drum of the wall-mounted washing machine and the wall surface, allowing the vibration of the outer drum during operation to be buffered and preventing it from impacting the wall. Furthermore, the installation gap between the outer drum and the wall surface allows for operation of the components mounted at the bottom of the outer drum during installation and subsequent maintenance, improving the convenience of installation and maintenance.

[0048] like Figure 1 and Figure 2As shown, in this embodiment, the bottom 19 of the outer cylinder is provided with a drive motor 4 facing the mounting wall. The rotor of the drive motor 4 is coaxially connected to the inner cylinder 3 inside the outer cylinder 2 via a rotating shaft 13, and is used to drive the inner cylinder 3 to rotate around the shaft. The bottom 19 of the outer cylinder is provided with a mounting groove 12 that is open facing the mounting wall and recessed into the outer cylinder 19. The drive motor 4 is at least partially located in the mounting groove 12.

[0049] By setting a mounting groove at the bottom of the outer drum, the drive motor is recessed and assembled in the mounting groove. The mounting groove protects the drive motor and prevents collisions between the drive motor and other components during the use of the wall-mounted washing machine. At the same time, since the drive motor is installed in the mounting groove, there is an overlap between the drive motor and the outer drum in the axial direction of the outer drum, which reduces the axial dimension of the wall-mounted washing machine.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, at least a portion of the drive motor 4 protrudes from the opening of the mounting groove 12, and the protruding end of the drive motor 4 relative to the base 9 is all positioned closer to the outer drum 2. With at least a portion of the drive motor 4 protruding from the opening of the mounting groove 12, the drive motor 4 is partially positioned in the gap between the bottom 19 of the outer drum and the mounting wall, utilizing this gap to connect with the external atmosphere of the washing machine. This improves airflow at the drive motor 4, thereby enhancing its heat dissipation performance.

[0051] Preferably, a vibration gap is maintained between the side of the drive motor 4 facing the mounting wall and the vertical plane where the protruding end of the base 9 is located. Thus, with the support of the base 9 of the wall-mounted washing machine, a vibration gap can be maintained between the drive motor 4 and the mounting wall, effectively preventing damage to the drive motor 4 from the vibration of the outer drum 2 during the operation of the wall-mounted washing machine.

[0052] Example 3

[0053] like Figure 1 and Figure 2 As shown in the figure, this embodiment introduces a wall-mounted washing machine, which includes an outer drum 2. The outer drum 2 is covered with an outer shell 1. The outer shell 1 and the outer drum 2 are detachably connected by a snap-fit ​​structure. The outer circumference of the outer drum 2 is provided with an outwardly protruding snap-fit ​​11. The outer shell 1 is provided with a corresponding snap-fit ​​groove 10 at a corresponding position. The snap-fit ​​11 and the snap-fit ​​groove 10 are detachably snapped together.

[0054] By covering the outer drum with an outer shell, the outer shell can conceal the outside of the drum, which not only improves the aesthetics of the wall-mounted washing machine, but also allows for the assembly of other components in the gap between the outer shell and the drum. At the same time, the end of the outer shell facing the mounting wall is connected to the bottom of the drum with a snap-fit ​​joint, which not only makes the assembly of the outer shell and the drum more convenient, but also connects the outer shell and the drum to the mounting wall to improve the assembly reliability of the drum. In addition, because the outer shell and the drum are assembled with a snap-fit ​​joint, the outer shell can also be easily disassembled and installed, allowing users to replace the outer shell, thus enriching the user-friendliness and versatility of the washing machine.

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, multiple feet 9 are arranged on the outer periphery of the outer cylinder 2. Each foot 9 has a locking protrusion 11 protruding radially outward along the outer periphery of the outer cylinder 2. The shell 1 has corresponding slots 10 at their respective positions, which engage with each locking protrusion 11, allowing for a detachable locking protrusion connection between the locking protrusion 11 and the slot 10 using the elastic deformation of the shell 1 itself. Preferably, in this embodiment, the locking protrusion 11 can also be configured as a spring sheet, telescopic block, or other structure capable of elastic deformation.

[0056] After the outer shell 1 is correspondingly installed on the outer cylinder 2, each locking protrusion 11 can extend into the locking groove 10, achieving the effect of locking and connecting the outer shell 1 with the outer cylinder 2 from multiple positions. At the same time, since the base 9 is thickened to facilitate bolt assembly, its material strength and / or wall thickness are strengthened to make the base 9 the point of maximum strength on the outer cylinder 2; by setting the locking protrusion 11 at the base 9, the locking protrusion 11 is installed at the point of highest strength in the entire outer cylinder 2, making the locking assembly of the locking protrusion 11 and the locking groove 10 more secure.

[0057] Preferably, the protruding end faces of each foot 9 are in the same vertical plane, so that the protruding end faces of each foot 9 of the wall-mounted washing machine can fit and contact the vertically extending mounting wall, making the wall-mounted washing machine more stable.

[0058] In this embodiment, each slot 10 is a notch that penetrates the side wall of the housing 1. The corresponding protrusion 11 is inserted into the slot 10 and fills the notch. The side of the protrusion 11 facing outward along the outer cylinder 2 is flush with the outer wall of the housing 1, so that the protrusion 11 can seal the notch and make the outer wall of the housing 1 form a smooth wall surface. This not only improves the aesthetics, but also reduces the occurrence of hanging lint, scratching items, etc.

[0059] Example 4

[0060] like Figures 2 to 4 As shown in the figure, this embodiment introduces a wall-mounted washing machine, which includes,

[0061] The outer cylinder 2 is fixed to the wall surface by mounting screws that pass through the base feet 9 provided at the bottom of the outer cylinder 19;

[0062] The inner cylinder 3 is rotatably installed inside the outer cylinder 2;

[0063] The door body 5 is installed on the outer cylinder 2, allowing the outer cylinder opening 20 to be opened and closed;

[0064] The door body 5 is equipped with a rotatable inner cylinder cover 6 on the side facing the outer cylinder 2. When the door body 5 closes the outer cylinder opening 20, the inner cylinder cover 6 closes the inner cylinder opening 17 accordingly and can rotate around the axis together with the inner cylinder 3. After the door body 5 is closed, the inner cylinder cover 6 closes the inner cylinder opening 17 accordingly, and the inner cylinder 3 forms a sealed water container.

[0065] With the above-described design, an openable and closable inner drum cover is installed at the opening of the wall-mounted washing machine. This allows for controlled sealing of the inner drum opening, ensuring that the inner drum forms a sealed water container during washing. This prevents water from flowing between the inner and outer drums, achieving a self-cleaning effect for the inner drum. Simultaneously, the door can cover the inner drum cover, which rotates with the inner drum, effectively preventing contact during washing. Furthermore, the linked opening and closing mechanism between the inner drum cover and the door allows users to control the simultaneous opening and closing of the inner drum cover with a single operation of the door.

[0066] like Figures 2 to 4 As shown, in this embodiment, a non-contact magnetic levitation bearing is installed on the door body 5. The shaft 24 of the inner cylinder cover 6 is coaxially inserted into the non-contact magnetic levitation bearing. Through the action of the non-contact magnetic levitation bearing, the shaft 24 can rotate around the shaft and maintain axial connection with the door body 5, thus moving together. This allows the inner cylinder cover 6 to be installed on the door body 5 in a way that allows it to rotate around the shaft and move together with the door body 5.

[0067] like Figures 2 to 4 As shown, in this embodiment, an annular mounting base 25 is installed on the door body 5. Multiple silicon steel sheets 26 are arranged radially and at an annular interval angle inside the annular mounting base 25. Each silicon steel sheet 26 is surrounded by a coil 27. The center of the inner cylinder cover 6 is provided with a shaft 24 made of magnetic material. The shaft 24 protrudes and extends towards one side of the door body 5. The extended end of the shaft 24 is inserted into the inner circumference of the annular mounting base 25. The outer circumference dimension of the extended end of the shaft 24 is smaller than the inner circumference radial dimension of the annular mounting base 25. This is used to generate electromagnetic driving force after the coil 27 is energized to drive the shaft 24 to a position coaxial with the annular mounting base 25 and maintain a certain suspension gap with the inner circumference of the annular mounting base 25. The shaft 24 is in a suspended state.

[0068] like Figures 2 to 4As shown, when the shaft 24 is suspended under the action of the energized coil 27, the axis of the shaft 24 is coaxial with the annular mounting base 25, and the outer wall of the shaft 24 is kept at a distance from the mounting base 25 and the buckle 28, so that the shaft 24 does not come into contact with other external parts, thereby reducing the friction when the shaft rotates; at the same time, since the shaft 24 at the inner drum opening 17 is supported by a non-contact magnetic levitation bearing and the rotating shaft 13 at the inner drum bottom 18 is supported by a bearing provided on the outer drum bottom 19, the front and rear ends of the inner drum 3 are supported respectively, which greatly reduces the vibration offset when the inner drum 3 rotates, thus effectively reducing the power loss and vibration noise during the operation of the wall-mounted washing machine.

[0069] like Figures 2 to 4 As shown, in this embodiment, an annular limiting groove 29 is provided on the outer wall of the extended end of the shaft 24, and multiple buckles 28 protruding radially toward the center are provided on the inner circumference side of the mounting base 25. The radial dimension of the annular surface formed by the inner circumference side of each buckle 28 is smaller than the outer circumference dimension of the annular limiting groove 29 and larger than the inner circumference dimension of the annular limiting groove 29, so as to ensure that at least some of the buckles 28 extend into the annular limiting groove 29, so that the shaft 24 is locked by the buckles 28 in the axial direction and the shaft 24 will not separate from the door body 5.

[0070] In this embodiment, the width of the annular limiting groove 29 in the axial direction of the shaft 24 is greater than the size of the portion of the buckle 28 that extends into the annular limiting groove 29, so as to ensure that when the shaft 24 is in a suspended state after being subjected to the electromagnetic force of the energized coil 27, a suspension gap is maintained between the shaft 24 and the buckle 28.

[0071] like Figures 2 to 4 As shown, in this embodiment, the shaft 24 is an independent component. The first end of the shaft 24 is fixedly connected to the inner cylinder cover 6 and can rotate around the shaft together with the inner cylinder cover 6. The second end is inserted into the annular mounting seat 25 of the door body 5 and is in a suspended state that can freely rotate around the shaft driven by the electromagnetic force generated by the energized electromagnetic coil 27. Preferably, the first end of the shaft 24 has multiple grooves 30, and the inner cylinder cover 6 has multiple protrusions 31 that extend into the grooves 30 one to one. Each groove 30 is located in a different position and on a different side of the inner cylinder cover 6, so that the inner cylinder cover 6 can be fixedly connected to the shaft 24 and rotate around the shaft together.

[0072] In this embodiment, the shaft 24 is entirely made of magnetic material, and the shaft 24 has a symmetrical structure relative to the axis; or, a portion of the shaft 24 is made of magnetic material, and the portion made of magnetic material is symmetrically distributed relative to the axis of the shaft 24. Preferably, at least the second end of the shaft 24 is made of magnetic material. With the above arrangement, the shaft can be positioned on the axis of the annular mounting base after being subjected to the electromagnetic driving force generated by the electromagnetic coil, thereby ensuring the smooth rotation of the inner cylinder.

[0073] In this embodiment, the outer cylinder 2 is provided with a first locking structure corresponding to locking or unlocking the door 5; the inner cylinder 3 is provided with a second locking structure corresponding to locking or unlocking the inner cylinder cover 6, which is used to drive the inner cylinder cover 6 and the inner cylinder 3 to rotate together. The aforementioned first locking structure and second locking structure can be any existing lock structure that can lock or unlock between the door and the cylinder; preferably, the first locking structure and the second locking structure can be linked for control, so as to realize the synchronous or linked opening and closing of the two locking structures, thereby achieving the effect of linked control of the door 5 and the inner cylinder cover 6 (not shown in the figures).

[0074] In this embodiment, a sealing structure is provided at the junction of the inner cylinder cover 6 and the inner cylinder opening 17. The sealing structure is installed at the inner cylinder cover 6 and / or the inner cylinder opening 17 so that after the inner cylinder cover 6 closes the inner cylinder opening 17, the sealing structure closes the junction of the two, thereby achieving the effect of closing the inner cylinder opening 17.

[0075] Preferred, such as Figure 1 and Figure 2 As shown, the inner cylinder cover 6 is coaxially arranged with the inner cylinder 3, and the radial dimension of the outer circumference of the inner cylinder cover 6 is greater than or equal to the dimension of the inner cylinder opening 17. A sealing ring 32 is provided on the outer circumference of the inner cylinder cover 6 facing the inner cylinder 3. The sealing ring 32 is made of rubber or other materials that can produce elastic deformation, so as to use its elastic deformation to seal the contact between the inner cylinder cover 6 and the inner cylinder opening 17.

[0076] Figure 2 As shown, in this embodiment, the outer cylinder 2 is covered by an outer shell 1, and the outer shell 1 is detachably connected to the outer cylinder 2 via a snap-fit ​​structure. The door 5 is mounted on the outer shell 1 and / or the outer cylinder 2 via a hinge structure, allowing it to rotate outwards to open and close. In this embodiment, the door 5 can be mounted on the outer cylinder 2, on the outer shell 1, or connected to both the outer cylinder 2 and the outer shell 1.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
