The inner cylinder assembly 10 includes an inner cylinder 101, a lock 102, a button 103 and a first elastic member 104. The outer cylinder assembly 20 includes an outer cylinder 201. The inner cylinder assembly 10 in the locked state includes the state of the inner cylinder assembly 10 when the inner cylinder assembly 10 and the outer cylinder assembly 20 in the drum structure 100 are locked together, and also includes the free state of the inner cylinder assembly 10 when the drum structure 100 is not equipped with the outer cylinder assembly 20. The inner cylinder assembly 10 in the unlocked state refers to the state of the inner cylinder assembly 10 when the inner cylinder assembly 10 and the outer cylinder assembly 20 in the drum structure 100 can be separated under the action of an external force.

[0059] like Figure 4 As shown, the inner cylinder 101 is a hollow cylindrical structure. The present application does not specifically limit the material and shape of the inner cylinder 101. For example: the material of the inner cylinder 101 can be plastic or metal; the shape of the inner cylinder 101 can be cylindrical or prismatic. The cylinder wall 114 of the inner cylinder 101 has a first through hole 110 that is interconnected with the cavity 113 of the inner cylinder 101. Specifically, the cylinder wall 114 of the inner cylinder 101 includes a first surface 111 and a second surface 112 that are arranged opposite to each other. The first surface 111 forms the outer surface of the inner cylinder 101. The second surface 112 forms the inner surface of the inner cylinder 101. The area surrounded by the second surface 112 forms the cavity 113 of the inner cylinder 101. The first through hole 110 penetrates the cylinder wall 114 of the inner cylinder 101. It can be understood that the first through hole 110 includes a first opening and a second opening that are arranged opposite to each other. The first opening is flush with the first surface 111. The second opening is flush with the second surface 112. The present application does not specifically limit the shape of the first through hole 110. For example, the shape of the first through hole 110 can be rectangular, square, or circular.

[0060] Please refer to Figures 2 to 5, the lock buckle 102 is used to achieve the locking of the inner cylinder 101 and the external cleaning component. In the present application, the lock buckle 102 is used to achieve the locking of the inner cylinder 101 and the outer cylinder 201. The present application does not specifically limit the material of the lock buckle 102. For example: the material of the lock buckle 102 can be plastic or metal. The material of the lock buckle 102 can be the same as or different from the material of the inner cylinder 101. One end 121 of the lock buckle 102 is located in the cavity 113 of the inner cylinder 101, and the other end 122 of the lock buckle 102 passes through the first through hole 110 outside the inner cylinder 101 when in the locked state, and the other end 122 of the lock buckle 102 is located in the first through hole 110 or the cavity 113 of the inner cylinder 101 when in the unlocked state. The lock buckle 102 has a second through hole 120. Among them, one end 121 of the lock buckle 102 is spaced apart from the cylinder wall 114 of the inner cylinder 101 in the locked state, and one end 121 of the lock buckle 102 is spaced apart from the cylinder wall 114 of the inner cylinder 101 in the unlocked state. The present application does not specifically limit the protrusion amount of the other end 122 of the lock buckle 102 relative to the first surface 111 in the locked state, as long as it can achieve a specific locking function. The present application does not specifically limit the recessed amount of the other end 122 of the lock buckle 102 relative to the first surface 111 in the unlocked state, as long as it can achieve a specific unlocking function. In a possible embodiment, the other end 122 of the lock buckle 102 is located in the first through hole 110 in the unlocked state. In this embodiment, the movement displacement of the lock buckle 102 when switching between the locked state and the unlocked state is small. In another possible embodiment, the other end 122 of the lock buckle 102 is located in the cavity 113 of the inner cylinder 101 in the unlocked state. In this embodiment, the movement displacement of the lock buckle 102 when switching between the locked state and the unlocked state is large.

[0061] Please refer to Figures 2 to 6, the button 103 can exert a certain unlocking force on the lock buckle 102 under the action of external force, so as to drive the lock buckle 102 to generate a motion displacement that can realize switching from the locked state to the unlocked state. The material of the button 103 is not specifically limited in this application. For example, the material of the button 103 can be plastic or metal. The material of the button 103 can be the same as or different from the material of the inner cylinder 101. The material of the button 103 can be the same as or different from the material of the lock buckle 102. In the locked state, one end 131 of the button 103 is located outside the inner cylinder 101, and the other end 132 of the button 103 is located in the cavity 113 of the inner cylinder 101, and the other end 132 of the button 103 is penetrated in the second through hole 120 and cooperates with the hole wall of the second through hole 120. The extension amount of one end 131 of the button 103 relative to the inner cylinder 101 in the locked state is not specifically limited in this application, and it can be realized to facilitate the user to apply external force. The present application does not specifically limit the amount of the other end 132 of the button 103 to extend relative to the inner tube 101, and it is sufficient that the other end 132 of the button 103 is inserted into the second through hole 120 and cooperates with the hole wall of the second through hole 120. In a possible embodiment, the other end 132 of the button 103 passes through the second through hole 120, and the other end 132 of the button 103 protrudes relative to the lock buckle 102 in both the locked state and the unlocked state, and the protrusion of the other end 132 of the button 103 relative to the lock buckle 102 in the locked state is less than the protrusion of the other end 132 of the button 103 relative to the lock buckle 102 in the unlocked state. When the button 103 moves along the first direction under the action of an external force, it drives the lock buckle 102 to switch from the locked state to the unlocked state. It can be understood that when the button 103 moves under the action of an external force, it can drive the lock buckle 102 to produce a corresponding movement. The first direction in the embodiment of the present application can refer to the attached Figure 3 In the X direction, the direction opposite to the direction indicated by the arrow is the opposite direction of the first direction. The first direction and the direction opposite to the first direction are along the axial direction of the inner cylinder 101.

[0062] The first elastic member 104 may be a spring, a bellows, etc. In the embodiment of the present application, the first elastic member 104 is a spring as an example. The first elastic member 104 is arranged between the other end 132 of the button 103 and the tube wall 114 of the inner tube 101, or the first elastic member 104 is arranged between the one end 121 of the lock buckle 102 and the tube wall 114 of the inner tube 101.

[0063] In a possible embodiment, the first elastic member 104 is disposed between one end 121 of the lock buckle 102 and the cylinder wall 114 of the inner cylinder 101. The first elastic member 104 is disposed between one end 121 of the lock buckle 102 and the cylinder wall 114 of the inner cylinder 101, which can be understood as one end of the first elastic member 104 is connected to one end 121 of the lock buckle 102, and the other end of the first elastic member 104 is connected to the cylinder wall 114 of the inner cylinder 101. At this time, one end of the first elastic member 104 and one end 121 of the lock buckle 102 can be directly connected or indirectly connected. The other end of the first elastic member 104 and the cylinder wall 114 of the inner cylinder 101 can be directly connected or indirectly connected. One end of the first elastic member 104 is directly connected to one end 121 of the lock buckle 102, which means that one end of the first elastic member 104 is sleeved on one end 121 of the lock buckle 102, or one end of the first elastic member 104 is fixedly connected to one end 121 of the lock buckle 102, for example, by welding, bonding, etc. One end of the first elastic member 104 is indirectly connected to one end 121 of the lock buckle 102, which means that one end of the first elastic member 104 is connected to one end 121 of the lock buckle 102 through other structural members. The other end of the first elastic member 104 is directly connected to the cylinder wall 114 of the inner cylinder 101, which means that the other end of the first elastic member 104 is sleeved on the cylinder wall 114 of the inner cylinder 101, or the other end of the first elastic member 104 is fixedly connected to the cylinder wall 114 of the inner cylinder 101, for example, by welding, bonding, etc. One end of the first elastic member 104 is indirectly connected to the cylinder wall 114 of the inner cylinder 101 , which means that the other end of the first elastic member 104 is connected to the cylinder wall 114 of the inner cylinder 101 through other structural members.

[0064] In the unlocked state, the first elastic member 104 is in a compressed state. It can be understood that in the unlocked state, the button 103 moves along the first direction under the action of an external force, driving the lock buckle 102 to move, and the first elastic member 104 is compressed by the squeeze of the lock buckle 102.

[0065] The first elastic member 104 gradually recovers and drives the button 103 to move in the reverse direction along the first direction, and drives the lock buckle 102 to switch from the unlocked state to the locked state. The process of the first elastic member 104 gradually recovering refers to the process of the first elastic member 104 gradually extending from the compressed state to the original length state. It can be understood that when the external force acting on the button 103 is withdrawn, the first elastic member 104 will gradually recover, so as to drive the button 103 to move in the reverse direction along the first direction, and drive the lock buckle 102 to switch from the unlocked state to the locked state. In the embodiment in which the first elastic member 104 is arranged between the other end 132 of the button 103 and the cylinder wall 114 of the inner cylinder 101, the first elastic member 104 gradually recovers and drives the button 103 to move in the reverse direction along the first direction. At this time, the matching state of the button 103 and the lock buckle 102 changes, driving the lock buckle 102 to switch from the unlocked state to the locked state. In the embodiment where the first elastic member 104 is disposed between one end 121 of the lock buckle 102 and the tube wall 114 of the inner tube 101, the first elastic member 104 first drives the lock buckle 102 to switch from the unlocked state to the locked state during the gradual recovery process, that is, first drives the lock buckle 102 to move, at which time the matching state of the lock buckle 102 and the button 103 changes, driving the button 103 to move in the opposite direction along the first direction.

[0066] The inner cylinder assembly 10 provided in the present application has a first through hole 110 interconnected with the cavity 113 of the inner cylinder 101 on the cylinder wall 114 of the inner cylinder 101, and one end 121 of the lock buckle 102 is located in the cavity 113 of the inner cylinder 101. In the locked state, one end 131 of the button 103 is located outside the inner cylinder 101, and the other end 132 of the button 103 is located in the cavity 113 of the inner cylinder 101, and the other end 132 of the button 103 is penetrated in the second through hole 120 of the lock buckle 102 and cooperates with the hole wall of the second through hole 120. In this way, when the button 103 moves in the first direction under the action of an external force, the lock buckle 102 can be driven to move, so that the other end 122 of the lock buckle 102 switches from passing through the first through hole 110 outside the inner cylinder 101 to being located in the first through hole 110 or in the cavity of the inner cylinder 101. 113, so that the other end 122 of the lock 102 no longer protrudes from the inner tube 101, thereby realizing the unlocking function of the inner tube assembly 10 and the external cleaning assembly, and the first elastic member 104 connected between the other end 132 of the button 103 and the tube wall 114 of the inner tube 101, or the first elastic member 104 connected between the one end 121 of the lock 102 and the tube wall 114 of the inner tube 101 is in a compressed state under the action of the button 103 in the unlocked state, so when the external force applied to the button 103 is cancelled, the first elastic member 104 will gradually recover, thereby driving the button 103 to move to restore the locked state, and driving the lock 102 to move to restore the locked state, thereby realizing the locking function of the inner tube assembly 10 and the external cleaning assembly, that is, it is conducive to the separate disassembly of the cleaning assembly, reducing resource waste and reducing costs. In addition, the inner tube assembly 10 realizes the locking and unlocking functions in a simple and reliable manner, and the user does not need to use tools when disassembling and assembling, and the operation is convenient.

[0067] In a possible embodiment, the lock buckle 102 moves along the second direction during the process of switching from the locked state to the unlocked state, and the lock buckle 102 moves in the opposite direction of the second direction during the process of switching from the unlocked state to the locked state, and the second direction is perpendicular to the first direction. Figure 2 In the Y direction shown, the direction opposite to the direction indicated by the arrow is the opposite direction of the second direction. The second direction and the direction opposite to the second direction are along the radial direction of the inner cylinder 101.

[0068] In the process of switching the inner cylinder assembly 10 between the locked state and the unlocked state, by making the movement direction of the lock buckle 102 perpendicular to the movement direction of the button 103, it is helpful to simplify the cooperation between the button 103 and the lock buckle 102, and improve the reliability and stability of the interaction and linkage between the button 103 and the lock buckle 102.

[0069] In one possible embodiment, please refer to Figure 7 and Figure 8, the first elastic member 104 is arranged between one end 121 of the lock buckle 102 and the cylinder wall 114 of the inner cylinder 101. The inner cylinder assembly 10 also includes a second elastic member 105. The second elastic member 105 can be a spring, a bellows, etc. In the embodiment of the present application, the second elastic member 105 is taken as an example of a spring. The second elastic member 105 is arranged between the other end 132 of the button 103 and the cylinder wall 114 of the inner cylinder 101.

[0070] The second elastic member 105 is disposed between the other end 132 of the button 103 and the cylinder wall 114 of the inner cylinder 101, which can be understood as one end of the second elastic member 105 is connected to the other end 132 of the button 103, and the other end of the second elastic member 105 is connected to the cylinder wall 114 of the inner cylinder 101. At this time, one end of the second elastic member 105 and the other end 132 of the button 103 can be directly connected or indirectly connected. The other end of the second elastic member 105 and the cylinder wall 114 of the inner cylinder 101 can be directly connected or indirectly connected. The direct connection between one end of the second elastic member 105 and the other end 132 of the button 103 can be that one end of the second elastic member 105 is sleeved on the other end 132 of the button 103, or one end of the second elastic member 105 and the other end 132 of the button 103 are fixedly connected, for example, by welding, bonding, etc. One end of the second elastic member 105 is indirectly connected to the other end 132 of the button 103, which means that one end of the second elastic member 105 is connected to the other end 132 of the button 103 through other structural members. The other end of the second elastic member 105 is directly connected to the wall 114 of the inner tube 101, which means that the other end of the second elastic member 105 is sleeved on the wall 114 of the inner tube 101, or the other end of the second elastic member 105 is fixedly connected to the wall 114 of the inner tube 101, for example, by welding or bonding. One end of the second elastic member 105 is indirectly connected to the wall 114 of the inner tube 101, which means that the other end of the second elastic member 105 is connected to the wall 114 of the inner tube 101 through other structural members.

[0071] It can be understood that one end of the first elastic member 104 is connected to one end 121 of the lock buckle 102, and the other end of the first elastic member 104 is connected to the cylinder wall 114 of the inner cylinder 101. One end of the second elastic member 105 is connected to the other end 132 of the button 103, and the other end of the second elastic member 105 is connected to the cylinder wall 114 of the inner cylinder 101. In a possible embodiment, one end of the first elastic member 104 is sleeved on one end 121 of the lock buckle 102, and the other end of the first elastic member 104 is directly fixedly connected to the second surface 112 of the inner cylinder 101, one end of the second elastic member 105 is sleeved on the other end 132 of the button 103, and the other end of the second elastic member 105 is indirectly connected to the cylinder wall 114 of the inner cylinder 101.

[0072] In the unlocked state, the second elastic member 105 is in a compressed state. It can be understood that in the unlocked state, the button 103 moves along the first direction under the action of an external force, driving the lock buckle 102 to move, and the second elastic member 105 is compressed by the squeezing action of the button 103.

[0073] During the gradual recovery of the second elastic member 105, the button 103 is driven to move in the opposite direction of the first direction, and the lock buckle 102 is driven to switch from the unlocked state to the locked state. It is understandable that when the external force acting on the button 103 is removed, the second elastic member 105 will gradually recover, thereby being able to drive the button 103 to move in the opposite direction of the first direction, and drive the lock buckle 102 to switch from the unlocked state to the locked state. In this embodiment, during the gradual recovery of the second elastic member 105, the button 103 is first driven to move in the opposite direction of the first direction, that is, the button 103 is first driven to move, at which time the matching state of the lock buckle 102 and the button 103 changes, driving the lock buckle 102 to move in the opposite direction of the second direction.

[0074] By arranging the first elastic member 104 between one end 121 of the lock buckle 102 and the tube wall 114 of the inner tube 101, and arranging the second elastic member 105 between the other end 132 of the button 103 and the tube wall 114 of the inner tube 101, when the external force is removed, the first elastic member 104 and the second elastic member 105 can be gradually restored, so that the button 103 and the lock buckle 102 have a greater driving force in the process of restoring from the unlocked state to the locked state, which can improve the efficiency and reliability of the restoration of the button 103 and the lock buckle 102.

[0075] The direction in which the first elastic member 104 is deformed is perpendicular to the direction in which the second elastic member 105 is deformed. In the embodiment of the present application, the direction in which the second elastic member 105 is deformed is the same as the direction in which the button 103 moves under the action of an external force, that is, the second elastic member 105 is deformed along the axial direction of the inner cylinder 101, and the direction in which the first elastic member 104 is deformed is the same as the direction in which the lock buckle 102 moves, that is, the first elastic member 104 is deformed along the radial direction of the inner cylinder 101. Specifically, in the process of the inner cylinder assembly 10 switching from the locked state to the unlocked state, the second elastic member 105 is gradually compressed along the axial direction of the inner cylinder 101, and the first elastic member 104 is gradually compressed along the radial direction of the inner cylinder 101. In the process of the inner cylinder assembly 10 switching from the unlocked state to the locked state, the second elastic member 105 is gradually extended along the axial direction of the inner cylinder 101, and the first elastic member 104 is gradually extended along the radial direction of the inner cylinder 101.

[0076] Please refer to Figure 7 and Figure 8, the hole wall of the second through hole 120 includes a first inclined surface 12a, and the key 103 includes a second inclined surface 13a, and the first inclined surface 12a is in contact with the second inclined surface 13a. Specifically, the hole wall of the second through hole 120 includes a first inclined surface 12a and an end surface 12b that are arranged opposite to each other. The first inclined surface 12a and the end surface 12b are arranged opposite to each other along the movement direction of the lock buckle 102, that is, the second direction. The key 103 includes a second inclined surface 13a. The second inclined surface 13a is in contact with the first inclined surface 12a, and the key 103 is spaced from the end surface 12b. The present application does not make specific restrictions on the inclination angles of the first inclined surface 12a and the second inclined surface 13a, and it is sufficient to achieve the contact and cooperation between the second inclined surface 13a and the first inclined surface 12a, and the key 103 and the lock buckle 102 can undergo corresponding movements. The key 103 is spaced apart from the end surface 12b to ensure that when the key 103 and the lock buckle 102 are in contact and matched through the second inclined surface 13a and the first inclined surface 12a, no interference occurs between the key 103 and the lock buckle 102 during the process of switching between the unlocked state and the lock buckle 102 state.

The hole wall of the second through hole 120 and the button 103 are slidably matched through the inclined groove 123 and the guide column 133.

[0078] In the embodiment of the present application, the hole wall of the second through hole 120 includes an inclined groove 123, and the button 103 includes a guide column 133 as an example. Among them, the hole wall of the second through hole 120 may include one or more inclined grooves 123. The button 103 may include one or more guide columns 133.

The third direction is perpendicular to the first direction and perpendicular to the second direction. The button 103 includes two guide columns 133 arranged opposite to each other along the third direction. The guide column 133 extends into the inclined groove 123. During the process of switching the inner cylinder assembly 10 between the locked state and the unlocked state, the guide column 133 slides in the inclined groove 123 to drive the lock buckle 102 to move in the second direction or in the reverse direction of the second direction. The present application does not specifically limit the inclination angle of the inclined groove 123, and it is sufficient that the lock buckle 102 can move accordingly when the guide column 133 slides in the inclined groove 123. The shape of the guide column 133 can be cylindrical.

[0085] Please refer to Figures 19 to 21 , Fig.19 for Figure 1 A cross-sectional schematic diagram of the drum structure 100 is shown. Fig. 20 for Figure 1 Another cross-sectional schematic diagram of the drum structure 100 is shown. Fig.21 for Figure 1 The cross-sectional schematic diagram of the outer cylinder assembly 20 in the drum structure 100 is shown. The outer cylinder 201 is a hollow cylindrical structure. The present application does not specifically limit the material and shape of the outer cylinder 201. For example: the material of the outer cylinder 201 can be plastic or metal; the shape of the outer cylinder 201 can be cylindrical or prismatic. In a possible embodiment, the shape of the outer cylinder 201 and the shape of the inner cylinder 101 are both cylindrical. The outer cylinder 201 is sleeved on the outer surface of the inner cylinder 101. It can be understood that the outer cylinder 201 surrounds the outer circumference of the inner cylinder 101. The inner surface of the outer cylinder 201 is provided with a lock hole 210. Specifically, the cylinder wall of the outer cylinder 201 includes a third surface and a fourth surface arranged opposite to each other. The third surface forms the outer surface of the outer cylinder 201. The fourth surface forms the inner surface of the outer cylinder 201. The lock hole 210 has a third opening. The third opening is flush with the fourth surface. The hole wall of the lock hole 210 is recessed relative to the fourth surface. The present application does not specifically limit the shape of the lock hole 210. For example, the lock hole 210 may be rectangular, square, or circular. The other end 122 of the lock buckle 102 is located in the lock hole 210 in the locked state, so that the outer tube 201 is locked with the inner tube 101.

[0086] In one possible embodiment, please refer to Fig. 22 and Fig.23 , the other end 122 of the lock buckle 102 also includes a third inclined surface 12c. During the assembly of the outer cylinder assembly 20 and the inner cylinder assembly 10, the outer cylinder assembly 20 moves in the opposite direction of the first direction, and the inner surface of the outer cylinder 201 contacts the third inclined surface 12c. The present application does not specifically limit the inclination angle of the third inclined surface 12c, and it is sufficient that the lock buckle 102 can move accordingly when the inner surface of the outer cylinder 201 contacts the third inclined surface 12c.

[0087] By making the other end 122 of the lock buckle 102 also include a third inclined surface 12c, the third inclined surface 12c contacts the inner surface of the outer cylinder 201 during the assembly process of the outer cylinder assembly 20 and the inner cylinder assembly 10. In this way, during the assembly process of the outer cylinder assembly 20 and the inner cylinder assembly 10, a certain force can be applied to the lock buckle 102 through the outer cylinder assembly 20, so that the lock buckle 102 moves along the second direction to retract into the inner cylinder 101, thereby facilitating the installation of the drum structure 100 without the aid of tools.

[0088] The outer cylinder assembly 20 further includes a cleaning member 202 fixedly mounted on the outer surface of the outer cylinder 201. The cleaning member 202 may be a brush, a sponge, or a sticky cloth. When the cleaning member 202 is a sponge or a sticky cloth, the cleaning member 202 may be fixed to the outer surface of the outer cylinder 201 by bonding. In the present application, the cleaning member 202 and the outer cylinder 201 are not removable or are difficult to removable.

In one possible embodiment, the handle may be connected to the outer drum 201. In another possible embodiment, the handle is connected to the inner drum 101 or the button bracket 107. Taking the connection between the handle and the button bracket 107 as an example, the handle and the button bracket 107 may be connected in a detachable manner or in a non-detachable manner. By providing a handle, the drum structure 100 can be conveniently taken, and by providing a handle in a manner of connecting the handle to the inner drum assembly 10, when the cleaning member 202 is replaced, there is no need to replace the handle, which can further reduce costs.

Fig.28 The movement direction of the lock buckle 102 is illustrated in the figure. At this time, when the lock hole 210 of the outer tube assembly 20 is aligned with the lock buckle 102, the lock buckle 102 extends into the lock hole 210 under the action of the first elastic member 104, so that the outer tube assembly 20 and the inner tube assembly 10 are in a locked state.
