[0062] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be described clearly and completely below in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0063] As shown in Figures 1-9 The utility model relates to a garbage can, including barrel body 10 and with the sleeve 20 of barrel body 10 set, the sleeve 20 has first position and second position on barrel body 10, the sleeve 20 is relative barrel body 10 and switches between first position and second position, one of barrel body 10 and sleeve 20 is equipped with the guide structure 11 and limiting part 12 of intercommunication, another is equipped with the moving part 21 of cooperation with guide structure 11, when sleeve 20 is driven and moves relative barrel body 10 from first position, moving part 21 moves along guide structure 11 and makes barrel body 10 relative rotation with sleeve 20, until moving part 21 moves to limiting part 12, to make sleeve 20 limit in second position.

[0064] The user only needs to move the sleeve 20 away from the barrel 10, and under the action of the guide structure 11, the barrel 10 and the sleeve 20 are relatively rotated, so that the moving part 21 can move along the guide structure 11 to the limiting part 12, so that the sleeve 20 and the barrel 10 are kept in the second position, so that the user only needs to pull the sleeve 20 away from the barrel 10 to keep the sleeve 20 in the position away from the barrel 10, which is more simple and better user experience.

[0065] The barrel 10 is used to form the main body of the garbage can, and is suitable for containing garbage. Generally, in order to facilitate use, a garbage bag 40 can be sleeved in the barrel 10. The barrel 10 is semi-closed in shape with a closed bottom and a barrel opening at the top. The barrel opening can be used for the garbage bag 40 to enter the barrel 10 through the barrel opening, or for garbage to enter the barrel 10 from the barrel opening. The preferred barrel 10 in this example is cylindrical, i.e., the barrel opening is a circular opening. Of course, the barrel 10 can also be provided in other shapes as needed.

[0066] The sleeve 20 is sleeved on the barrel 10 and can slide relative to the barrel 10. The preferred sleeve 20 in this example matches the shape of the barrel 10, i.e., the barrel 10 is cylindrical, and the sleeve 20 is also cylindrical, so that the sleeve 20 and the barrel 10 can smoothly slide relative to each other. The preferred sleeve 20 in this example is provided outside the barrel 10 and slides along the outer peripheral sidewall of the barrel 10. It can be understood that the sleeve 20 can also be provided inside the barrel 10 and slide along the inner peripheral sidewall of the barrel 10. The sleeve 20 has a first position and a second position on the barrel 10. The preferred first position is close to the bottom of the barrel 10, and the second position is away from the bottom of the barrel 10, i.e., close to the barrel opening. The sleeve 20 can slide relative to the barrel 10 between the first position and the second position.

[0067] The sliding movement between the sleeve 20 and the barrel 10 is realized through the cooperation of the guide structure 11 and the moving part 21. The preferred moving part 21 moves along the extension direction of the guide structure 11 to drive the barrel 10 and the sleeve 20 to relatively rotate. In this example, the moving part 21 is provided on the inner wall of the sleeve 20, and the guide structure 11 is provided on the outer wall of the barrel 10, so that when the user pulls the sleeve 20 in the forward direction, the moving part 21 is simultaneously driven to move along the guide structure 11.

[0068] It can be understood that the moving part 21 can also be provided on the outer wall of the barrel 10, and the guide structure 11 can be provided on the inner wall of the sleeve 20, which can also realize the switching of the sleeve 20 between the first position and the second position relative to the barrel 10.

[0069] It can be understood that the moving part 21 can also be arranged on the inner wall of the barrel body 10, and the guide structure 11 is arranged on the outer wall of the sleeve 20, so that the sleeve 20 slides along the inner wall of the barrel body 10, and the sleeve 20 can also be switched between the first position and the second position relative to the barrel body 10.

[0070] It can be understood that the moving part 21 can also be arranged on the outer wall of the sleeve 20, and the guide structure 11 is arranged on the inner wall of the barrel body 10, so that the sleeve 20 slides along the inner wall of the barrel body 10, and the sleeve 20 can also be switched between the first position and the second position relative to the barrel body 10.

[0071] The limiting part 12 is used in cooperation with the moving part 21 to limit the movement of the moving part 21, that is, when the moving part 21 moves along the guide structure 11 to the limiting part 12 according to the preset route, when the driving of the sleeve 20 is cancelled, the moving part 21 cannot be reset along the guide structure 11 in the opposite direction of the preset route, so that the sleeve 20 moves to the second position relative to the barrel body 10 and remains in the second position. The limiting part 12 is in communication with the guide structure 11, so that the moving part 21 can move along the guide structure 11 to enter the limiting part 12. In this example, the side of the limiting part 12 is connected to the side of the guide structure 11, so that the movement of the moving part 21 between them is smoother. Of course, the limiting part 12 and the guide structure 11 can also be connected in a non-physical manner, as long as the moving part 21 can move along the guide structure 11 to enter the limiting part 12. In this example, the limiting part 12 is a recess structure, so that when the moving part 21 moves to the bottom of the recess, the moving part 21 can be limited. It can be understood that the limiting part 12 can also be a clamping structure, a magnetic attraction structure, an adhesive structure, etc., as long as the moving part 21 can be limited in the limiting part 12 and cannot move.

[0072] When the sleeve 20 moves away from the barrel body 10 in the forward direction, the preferred forward direction is the direction away from the barrel body 10 along the central axis of the barrel body 10. Correspondingly, the reverse direction is the direction approaching the barrel body 10 along the central axis of the barrel body 10. In this example, the preferred direction of the sleeve 20 away from the barrel body 10 is that the sleeve 20 moves away from the bottom of the barrel body 10.

[0073] The moving part 21 drives the barrel body 10 and the sleeve 20 to rotate relative to each other under the action of the guide structure 11, so that the moving part 21 moves into the limiting part 12. The preferred guide structure 11 is inclined relative to the central axis of the barrel body 10, so that when the sleeve 20 moves in the forward direction, the moving part 21 moves relative to the inclined guide structure 11, so that the sleeve 20 rotates relative to the barrel body 10. Until the moving part 21 moves into the limiting part 12.

[0074] In an alternative implementation, the guide structure 11 comprises a first guide portion 111, the limiting portion 12 is arranged at the side of the first guide portion 111, and the first guide portion 111 is provided with a first guide surface 112 at one end close to the limiting portion 12. The sleeve 20 is driven to move relative to the barrel 10 from the first position, so that the moving portion 21 moves along the first guide portion 111. When the moving portion 21 moves to abut against the first guide surface 112 and slides along the first guide surface 112, the barrel 10 rotates relative to the sleeve 20. In this example, the guide structure 11 is arranged on the barrel 10, and the moving portion 21 is arranged on the sleeve 20. When the sleeve 20 moves upward relative to the barrel 10, it drives the moving portion 21 to move along the guide structure 11 to the second position. Preferably, the limiting portion 12 is arranged at the side of the first guide portion 111, and the side edges of the two are connected, so that the limiting portion 12 and the first guide portion 111 are arranged in a staggered manner. When the moving portion 21 moves from the first guide portion 111 to the limiting portion 12 under the action of the first guide surface 112, the moving portion 21 rotates relative to the circumference of the barrel 10, i.e., the sleeve 20 rotates relative to the barrel 10.

[0075] It can be understood that the guide structure 11 is arranged on the sleeve 20, and the moving portion 21 is arranged on the barrel 10. When the sleeve 20 moves upward relative to the barrel 10, it drives the guide structure 11 to move, so that the guide structure 11 slides relative to the moving portion 21, and the moving portion 21 rotates under the action of the first guide surface 112 and is limited in the limiting portion 12, i.e., the sleeve 20 is in the second position.

[0076] In an alternative implementation, the first guide surface 112 is an inclined plane. When the first guide surface 112 is arranged as an inclined plane, the first guide portion 111 does not need to be arranged as an inclined plane as a whole, only part of the first guide surface 112 needs to be inclined, so that the barrel 10 rotates relative to the sleeve 20 by a smaller angle to keep the sleeve 20 in the second position, which provides a better user experience and reduces the difficulty of mold production. In addition, the arrangement of the plane allows the barrel 10 to rotate relative to the sleeve 20 at a constant speed when the sleeve 20 moves forward, which provides a better user experience. Preferably, the first guide surface 112 is arranged to be inclined toward the direction of the limiting portion 12.

[0077] It can be understood that the first guide surface 112 can also be arranged as an inclined arc surface.

[0078] The limiting portion 12 is preferably arranged at the side of the first guide portion 111, and the side edges of the two are connected. When the first guide surface 112 is inclined towards the direction of the limiting portion 12, one end of the first guide surface 112 is connected with the first guide portion 111. The other end extends into the limiting portion 12, so that the moving portion 21 can move along the first guide surface 112 from the first guide portion 111 into the limiting portion 12. Preferably, a smooth transition is formed at the connection between the first guide surface 112 and the first guide portion 111, so that the movement of the moving portion 21 is smoother.

[0079] In an alternative embodiment, the first guide surface 112 has a first end 1121 and a second end 1122 in sequence in the direction away from the first guide portion 111. The first end 1121 and the second end 1122 are respectively located on both sides of the moving track of the moving portion 21 in the first guide portion 111. When the moving portion 21 moves along the first guide portion 111 to abut against the first end 1121 and slides along the first guide surface 112 from the first end 1121 to the second end 1122, the barrel 10 rotates relative to the sleeve 20. The first end 1121 is the starting end of the abutment between the moving portion 21 and the first guide surface 112, and the second end 1122 is the limit position after the moving portion 21 moves along the first guide surface 112. Arranging the first end 1121 and the second end 1122 respectively on both sides of the moving track of the moving portion 21 facilitates the movement of the moving portion 21 along the first guide portion 111 to abut against the first guide surface 112. Preferably, the first end 1121 is in communication with the moving track of the moving portion 21 in the first guide portion 111, so that the moving portion 21 abuts against the first end 1121 when moving out of the first guide portion 111, and the movement of the moving portion 21 is smoother. In this example, the second end 1122 preferably passes the limiting portion 12 and approaches the side edge of the first guide portion 111, and the moving portion 21 is at least in the center of the limiting portion 12. When the moving portion 21 moves along the first guide surface 112 to the second end 1122, the moving portion 21 is in the limiting portion 12 or on the top of the limiting portion 12. Even if the cooperation between the moving portion 21 and the second end 1122 is disengaged, the moving portion 21 will also fall into the limiting portion 12 due to its own gravity, and will not enter the first guide portion 111 to reset to the initial position, causing the sleeve 20 to return to the first position.

[0080] In an alternative embodiment, the first guide surface 112 is provided with an extension 113 at the first end 1121 in the direction of the first guide portion 111, the moving portion 21 moves along the first guide portion 111 to abut against the extension 113, and moves along the extension 113 to abut against the first end 1121, the extension 113 is used to guide the moving portion 21 to abut against the first guide surface 112, and at the same time, when the moving portion 21 abuts against the first guide surface 112, the extension 113 limits the moving portion 21 from moving away from the second end 1122, so as to avoid the moving portion 21 from disengaging from the first end 1121, and in this example, the extension direction of the extension 113 is the same as the extension direction of the first guide portion 111, so as to facilitate the moving portion 21 to move from the first guide portion 111 to the extension 113.

[0081] In an alternative embodiment, when the sleeve 20 moves along the positive direction relative to the barrel 10, the moving portion 21 moves along the first guide surface 112 to the limit position, and when the driving of the sleeve 20 is cancelled, the moving portion 21 reversely moves into the limiting portion 12, so as to stably keep the sleeve 20 at the second position on the barrel 10, thereby avoiding the sleeve 20 from moving along the reverse direction to the initial position before lifting due to its own gravity, and at the same time, the sleeve 20 can also be reset relative to the barrel 10 when being touched.

[0082] In an alternative embodiment, the first guide surface 112 has the first end 1121 and the second end 1122 in the direction away from the first guide portion 111, the second end 1122 is correspondingly arranged with the limiting portion 12, and the moving portion 21 slides to abut against the second end 1122, and when the sleeve 20 is unloaded, the moving portion 21 slides into the limiting portion 12, so as to limit the sleeve 20 at the second position, and when the moving portion 21 moves along the first guide surface 112 to the second end 1122, i.e., the moving portion 21 is lifted upward to the limit position, at this time, the sleeve 20 is unloaded, and the sleeve 20 is limited at the second position, so that the user can operate more conveniently, and only needs to lift the sleeve 20 upward and then release the sleeve 20, and the sleeve 20 can be at the second position.

[0083] In an alternative embodiment, the first guide surface 112 has a limiting surface 114 extending towards the limiting portion 12 at the second end 1122, so that when the moving portion 21 moves to the limit position along the first guide surface 112, the limiting surface 114 limits the movement of the moving portion 21. The limiting surface 114 guides the moving portion 21 into the limiting portion 12 and limits the limit position of the moving portion 21. Preferably, the end of the limiting surface 114 away from the second end 1122 is connected to the side of the limiting portion 12 to prevent the moving portion 21 from moving out of the limiting portion 12.

[0084] In an alternative embodiment, the first guide portion 111 is arranged vertically on the barrel 10 or the sleeve 20. The vertical arrangement of the first guide portion 111 reduces the friction between the moving portion 21 and the first guide portion 111 when the user pulls the sleeve 20 upwards, allowing the sleeve 20 to be quickly lifted, providing a better user experience and facilitating production and processing.

[0085] In an alternative embodiment, the first guide portion 111 extends from the bottom of the barrel 10 to the top of the barrel 10, or the first guide portion 111 extends from the top of the sleeve 20 to the bottom of the sleeve 20. When the first guide portion 111 is arranged on the barrel 10, the first guide portion 111 extends from the bottom of the barrel 10 to the top of the barrel 10, so that the sleeve 20 can be pulled from a first position close to the bottom of the barrel 10 to a second position away from the bottom of the barrel 10. It is understood that when the first guide portion 111 is arranged on the sleeve 20 and the moving portion 21 is arranged on the top of the barrel 10, in the first position, the top of the sleeve 20 is close to the top of the barrel 10, and in the second position, the bottom of the sleeve 20 is close to the top of the barrel 10. The first guide portion 111 extends from the top of the sleeve 20 to the bottom of the sleeve 20, so that the sleeve 20 can be pulled from the first position to the second position.

[0086] In an alternative embodiment, the limiting portion 12 has a limiting recess 121 recessed away from the first guide surface 112, so that when the moving portion 21 moves to the limiting recess 121, the sleeve 20 is limited to the second position. The simple way of fixing the moving portion 21 by the limiting recess 121 facilitates production and processing, and also facilitates the removal of the moving portion 21 from the limiting portion 12. When the moving portion 21 moves to the lowest end of the recess, the moving portion 21 cannot move freely without force, and will not move into the first guide portion 111 to reset the sleeve 20 to the first position of the barrel 10, so that the sleeve 20 and the barrel 10 remain stable and reliable in the second position.

[0087] It can be understood that when the limiting portion 12 is provided as a buckle structure, a magnetic attraction structure or an adhesive structure, the side of the limiting portion 12 that cooperates with the moving portion 21 is directed towards the first guide surface 112, for example, when the limiting portion 12 is an adhesive structure, the side of the limiting portion 12 directed towards the first guide surface 112 is provided with an adhesive material such as a magic tape, so that when the moving portion 21 moves in the reverse direction and abuts against the limiting portion 12, the moving portion 21 can be adhered to the limiting portion 12 to limit the movement of the moving portion 21. Other structures are similar and will not be described herein.

[0088] In an optional embodiment, the limiting portion 12 has a third guide surface 122 that is inclined from one end close to the first guide surface 112 towards the limiting recess 121, when the sleeve 20 is unloaded, the moving portion 21 slides from the first guide surface 112 to the one end of the limiting portion 12 close to the first guide surface 112, and under the action of gravity of the sleeve 20, the moving portion 21 slides along the third guide surface 122 into the limiting recess 121. The third guide surface 122 is provided so that the one end of the limiting portion 12 close to the first guide surface 112 can be provided with a smaller height difference, so that the moving portion 21 can enter the limiting recess 121 with a smaller displacement, thereby reducing the damage of the moving portion 21 caused by violent collision with the limiting portion 12.

[0089] In an optional embodiment, the limiting portion 12 is provided at one end of the first guide surface 112 away from the first guide portion 111, when the sleeve 20 moves relative to the barrel 10 and the moving portion 21 moves to the limit position along the first guide surface 112, the moving portion 21 cooperates with the limiting portion 12 at the limit position, so that the sleeve 20 is limited to the second position. When the moving portion 21 is lifted to the limit position, the moving portion 21 cooperates with the limiting portion 12 at the limit position to limit, so that the user only needs to pull the sleeve 20 upwards to limit the sleeve 20, and the operation is more convenient. Preferably, the moving portion 21 and the limiting portion 12 can be cooperatively limited by magnetic attraction, clamping or adhesive means. For example, in the magnetic attraction connection mode, a magnet can be provided at one end of the first guide surface 112 away from the first guide portion 111, and another magnet or an iron block opposite in magnetic pole to the magnet is provided on the moving portion 21. When the moving portion 21 moves to the limit position along the first guide portion 111, i.e. at one end of the first guide surface 112 away from the first guide portion 111, the moving portion 21 is magnetically attracted at one end of the first guide surface 112 away from the first guide portion 111. Other modes are similar and will not be described herein.

[0090] In an alternative embodiment, the sleeve 20 is defined to rotate relative to the barrel 10 in a preset direction when moving from the first position to the second position, and when the sleeve 20 rotates relative to the barrel 10 in a direction opposite to the preset direction, the moving part 21 is moved from the limiting part 12 into the first guide part 111, and under the gravity of the sleeve 20, the moving part 21 moves along the first guide part 111 to an end away from the limiting part 12, so that the sleeve 20 is reset from the second position to the first position. The second guide part 115 is arranged to facilitate the reset of the sleeve 20 to the first position, so as to realize the free switching of the sleeve 20 between the first position and the second position on the barrel 10. In this example, the moving path of the sleeve 20 from the first position to the second position and the moving path of the sleeve 20 from the second position to the first position are arranged separately, on the one hand, it is convenient to operate, and different operation modes can be selected according to the position of the sleeve 20, so that interference does not occur. On the other hand, it also prevents the sleeve 20 from being easily reset to the first position along the reverse direction of the original moving path when moving from the first position to the second position, which affects the user's experience. It should be noted that in this example, the second guide part 115 is in communication with the first guide part 111 and the limiting part 12, respectively. The three parts can be connected through corresponding side edges, or can not be directly connected physically. As long as the moving part 21 can move along the first guide part 111 to the limiting part 12, and move from the limiting part 12 to the second guide part 115, and can also move from the second guide part 115 to the first guide part 111, that is, the moving part 21 moves circularly between the first guide part 111, the limiting part 12 and the second guide part 115, thereby driving the sleeve 20 to freely switch between the first position and the second position on the barrel 10.

[0091] In an alternative embodiment, the limiting part 12 has a limiting recess 121 recessed away from the first guide surface 112, and the sleeve 20 moves upward relative to the barrel 10 to disengage the moving part 21 from the limiting recess 121, and continue to rotate the sleeve 20 relative to the barrel 10 in a direction opposite to the preset direction, so that the sleeve 20 is reset from the second position to the first position, so as to facilitate the lifting movement of the sleeve 20 again, so that the moving part 21 can reciprocate between the first position and the second position.

[0092] In an alternative embodiment, the guide structure 11 further comprises a second guide portion 115, one end of the second guide portion 115 is in communication with the limiting portion 12, and the other end is in communication with the first guide portion 111, when the sleeve 20 rotates relative to the barrel 10, the moving portion 21 moves from the limiting portion 12 to the second guide portion 115; under the gravity of the sleeve 20, the moving portion 21 moves along the second guide portion 115 into the first guide portion 111, and continues to move along the first guide portion 111 to the end away from the limiting portion 12, so that the sleeve 20 is reset from the second position to the first position. The second guide portion 115 facilitates the resetting of the moving portion 21 to the first position, so as to facilitate the lifting movement of the sleeve 20 again, so that the moving portion 21 can reciprocate between the first position and the second position. When the moving portion 21 enters the second guide portion 115, the sleeve 20 resets by its own gravity, without the need for manual resetting by the user, providing a better experience.

[0093] In an alternative embodiment, the guide structure 11 further comprises a second guide surface 116, both ends of the second guide surface 116 correspond to the second guide portion 115 and the limiting portion 12 respectively; when the sleeve 20 is driven to move relative to the barrel 10, so that the moving portion 21 disengages from the limiting portion 12 to abut against the second guide surface 116 and slides along the second guide surface 116, the sleeve 20 rotates relative to the barrel 10. Through the guidance of the second guide surface 116, the moving portion 21 can move along a specified path from the limiting portion 12 to the second guide portion 115. In this example, the preferred second guide surface 116 is provided at the top end of the limiting portion 12 and extends from the limiting portion 12 into the second guide portion 115, so that when the sleeve 20 is driven, the moving portion 21 abuts against the second guide surface 116 and moves along the second guide surface 116 into the second guide portion 115.

[0094] It can be understood that the second guide surface 116 can also be provided between the limiting portion 12 and the second guide portion 115, i.e. both ends of the second guide surface 116 are connected to the side edges of the limiting portion 12 and the second guide portion 115, so that the moving portion 21 can move from the limiting portion 12 along the second guide surface 116 into the second guide portion 115.

[0095] It can be understood that the second guide surface 116 can also be non-physically connected with the second guide part 115, for example, when the second guide part 115 is a groove structure, the end of the second guide surface 116 extending to the top of the opening of the groove structure of the second guide part 115 is in communication with the second guide part 115, and the second guide surface 116 is not in contact with the second guide part 115, but the moving part 21 can move into the second guide part 115 along the second guide surface 116; similarly, the second guide surface 116 can also be non-physically connected with the limiting part 12, and the moving part 21 can also be moved into the second guide part 115 along the second guide surface 116.

[0096] In an optional embodiment, the second guide surface 116 has a third end 1161 and a fourth end 1162 in sequence along the moving direction of the moving part 21, and the third end 1161 and the fourth end 1162 are located on both sides of the limiting part 12, so that the moving part 21 moving out of the limiting part 12 will necessarily abut against the second guide surface 116, facilitating the movement of the moving part 21 along the second guide surface 116. Preferably, the third end 1161 at least extends beyond the lowest end of the limiting groove 121, and when the moving part 21 moves into the limiting part 12, the moving part 21 will generally be kept at the lowest part of the limiting part 12, i.e. the lowest end of the limiting groove 121, under the gravity of the sleeve 20 without external force. When the third end 1161 extends beyond the lowest end, the moving part 21 will first contact the third end 1161 when driven to move in the positive direction, thereby facilitating the movement of the moving part 21 along the second guide surface 116 to the fourth end 1162.

[0097] In the embodiment, the second guide surface 116 is connected with the first guide surface 112, so that there is no gap between the first guide surface 112 and the second guide surface 116, and when the moving part 21 moves in the positive direction and contacts the second guide surface 116, or when the moving part 21 moves along the first guide surface 112 to the limit position, the moving part 21 can be prevented from moving out of the guide structure 11. More specifically, the first guide surface 112 has a limiting surface 114 extending toward the limiting part 12 at the limit position where the moving part 21 abuts against it, and the second guide surface 116 is connected with the end of the limiting surface 114 away from the first guide surface 112 at the starting position where the moving part 21 abuts against it. The two are connected through the limiting surface 114. Since the first guide surface 112 and the second guide surface 116 are mutually parallel inclined inclined surfaces, preferably, the first guide surface 112, the second guide surface 116 and the limiting surface 114 form an “N” shape or an “M” shape.

[0098] In an alternative embodiment, the second guide portion 115 is bent away from the first guide portion 111, on the one hand, the second guide portion 115 can avoid the recessed limiting portion 12 structure, on the other hand, the second guide portion 115 forms an arc shape, so that the moving portion 21 moves faster when moving along the second guide surface 116, and is easier to reset, and the user experience is better.

[0099] In an alternative embodiment, the second guide portion 115 and the first guide portion 111 have a height difference between the communication position and the end of the first guide portion 111 away from the limiting portion 12, so that when the moving portion 21 moves along the first guide portion 111 to the second position, the moving portion 21 passes through the communication position, so that when the moving portion 21 moves upward, it first moves along the first guide portion 111 by a distance of the height difference, which guides the moving direction of the moving portion 21, so that the moving portion 21 can move in the vertical direction, and then pass through the communication position and continue to move along the first guide portion 111 towards the limiting portion 12, which can avoid the moving portion 21 moving into the second guide portion 115.

[0100] In an alternative embodiment, the first guide portion 111 has a fourth guide surface 119 inclined towards the second guide portion 115 at the communication position, so that the moving portion 21 abuts against the fourth guide surface 119 when moving to the communication position, and continues to move along the fourth guide surface 119 into the first guide portion 111. The fourth guide surface 119 is provided to guide the moving portion 21 to move along the fourth guide surface 119 into the first guide portion 111 when the moving portion 21 moves a distance of the height difference along the first guide portion 111 into the communication position, and the moving portion 21 may deviate towards the second guide portion 115 due to the absence of obstruction in the direction of the second guide portion 115 at the communication position. The fourth guide surface 119 is arranged at the communication position to guide the deviated moving portion 21 to move along the fourth guide surface 119 into the first guide portion 111, and move along the first guide portion 111 towards the limiting portion 12. Preferably, the communication position is a communication hole arranged on the first guide portion 111, so that the second guide portion 115 extends away from the first guide portion 111 from the position of the communication hole. Preferably, the fourth guide surface 119 is arranged at the end of the communication hole close to the limiting portion 12 and connected with the first guide portion 111, and the fourth guide surface 119 is inclined towards the second guide portion 115, so that the moving portion 21 abuts against the fourth guide surface 119 and moves along the inclined direction of the fourth guide surface 119 into the first guide portion 111.

[0101] In an alternative embodiment, the guide structure 11 further comprises a third guide portion 117, one end of which is in communication with the first guide portion 111 and the other end extends to the edge of the barrel 10 or the sleeve 20, so that the moving portion 21 enters the first guide portion 111 from the edge of the barrel 10 or the sleeve 20 along the third guide portion 117. In the case where the guide structure 11 is arranged in the barrel 10 and the moving portion 21 is arranged in the sleeve 20, the preferred third guide portion 117 is a slot-shaped channel, the part in communication with the outside has a notch, and the notch is arranged at the top edge of the barrel 10, so that the moving portion 21 can enter the third guide portion 117 through the notch. In order to facilitate the entry of the moving portion 21 into the third guide portion 117, the width of the notch can be set to be larger than the width of the third guide portion 117, i.e. the notch can be designed as a flared structure. In order to facilitate the rapid entry of the moving portion 21 into the third guide portion 117, the third guide portion 117 can also be designed in other shapes, such as a guide plane, as long as it can guide the moving portion 21 into the first guide portion 111.

[0102] It can be understood that when the guide structure 11 is arranged in the barrel 10 and the moving portion 21 is arranged in the barrel 10, the notch can be arranged at the edge of the bottom of the sleeve 20, so that when the sleeve 20 is arranged on the barrel 10, the notch at the edge of the bottom of the sleeve 20 cooperates with the moving portion 21 to facilitate the connection of the sleeve 20 to the barrel 10 from top to bottom.

[0103] In an alternative embodiment, the third guide portion 117 is in communication with the first guide portion 111 through a connecting portion 118, and the first guide surface 112 and the connecting portion 118 have a height difference, so that when the moving portion 21 moves along the first guide portion 111 to the second position, the moving portion 21 abuts against the first guide surface 112 by passing over the connecting portion 118. The connecting portion 118 is used to connect the third guide portion 117 and the first guide portion 111, and the preferred connecting portion 118 is a connecting hole, which is arranged on the side wall of the first guide portion 111, so that the third guide portion 117 is arranged on the side wall of the first guide portion 111 and covers the connecting hole, so that the moving portion 21 can enter the first guide portion 111 from the third guide portion 117 through the connecting hole. The shape of the connecting hole is adapted to the shape of the moving portion 21, and the connecting portion 118 can also be formed as a recess structure that allows the moving portion 21 to pass through. The connecting portion 118 can also be designed as a one-way channel that allows the moving portion 21 to move from the third guide portion 117 to the first guide portion 111 and prevents the moving portion 21 from moving from the first guide portion 111 to the third guide portion 117. The one-way channel is similar to the principle of a one-way valve, which will not be described here.

[0104] In an alternative embodiment, the limiting portion 12 and the third guiding portion 117 are arranged on opposite sides of the first guiding portion 111, so that the moving portion 21 is in different directions during the installation operation and the limiting operation, which can effectively avoid interference between different operation actions. Preferably, the opposite sides of the first guiding portion 111 are the two sides along the extension direction of the first guiding portion 111.

[0105] It can be understood that when the limiting portion 12 and the third guiding portion 117 are arranged on the same side of the first guiding portion 111, that is, the limiting portion 12 and the third guiding portion 117 are arranged on one side of the first guiding portion 111 in the extension direction, as long as the installation operation and the limiting operation of the moving portion 21 do not interfere with each other.

[0106] In an alternative embodiment, the guiding structure 11 is a groove-shaped channel, and the moving portion 21 is a sliding block, which is adapted to slide in the guiding structure 11, so as to better guide the sliding block and limit the movement of the sliding block in the groove-shaped channel, thereby avoiding derailment of the sliding block during movement. Preferably, the sliding block is a cylindrical protruding structure, so that the sliding block has an arc-shaped side surface to move more smoothly in the groove-shaped channel. In this example, the moving portion 21 is arranged in the sleeve 20, that is, the sliding block extends from the side wall of the sleeve 20 to form a cylindrical protruding structure. The sliding block can be integrally formed on the sleeve 20 or can be separately formed and then installed on the sleeve 20 through the mounting structure. It can be understood that when the moving portion 21 is arranged on the barrel 10, the arrangement manner is the same as that on the sleeve 20, which will not be described herein.

[0107] In an alternative embodiment, the groove-shaped channel side wall of the guiding structure 11 is recessed to form the limiting portion 12, which is simple in structure and convenient for production and processing.

[0108] In an alternative embodiment, the guiding structure 11 is provided with at least two, and the moving portion 21 is adapted to the guiding structure 11. Multiple guiding structures 11 and moving portions 21 are arranged, so that the relative sliding of the barrel 10 and the sleeve 20 is completed through the cooperation of multiple groups of moving portions 21 and guiding structures 11, so as to better enable the sleeve 20 to slide relative to the barrel 10 and avoid jamming during relative sliding.

[0109] In an alternative embodiment, the guiding structures 11 are uniformly distributed along the outer side wall of the barrel 10, and the moving portions 21 are uniformly distributed along the inner side wall of the sleeve 20, so that the sleeve 20 does not shake during movement relative to the barrel 10. When the guiding structure 11 is provided with two, the guiding structures 11 are symmetrically distributed on the barrel 10. When the guiding structure 11 is greater than or equal to three, the included angle between adjacent guiding structures 11 is equal.

[0110] It can be understood that when the guide structure 11 is arranged on the sleeve 20 or the inner side wall of the barrel 10, uniform distribution is also formed, which will not be described herein.

[0111] It can be understood that when the barrel 10 or the sleeve 20 is polygonal, and the guide structure 11 is arranged on the sleeve 20 or the barrel 10, the guide structure 11 can be arranged on each face.

[0112] In an optional embodiment, the garbage bag 40 is placed in the barrel 10, and when the bag opening moves away from the barrel 10 along with the sleeve 20, the volume of the garbage can is increased, and negative pressure is generated between the outer wall of the garbage bag 40 and the inner wall of the barrel 10 and the sleeve 20, so that the garbage bag 40 is attached to the inner wall of the barrel 10 and the sleeve 20, and the garbage bag 40 is automatically unfolded without the need for the user to manually unfold it, and the user experience is better.

[0113] In an optional embodiment, the bag opening is sleeved on the edge of the side of the sleeve 20 away from the barrel 10, so that a relatively closed space is formed between the outer wall of the garbage bag 40 and the inner wall of the barrel 10 and the sleeve 20, and when the sleeve 20 moves upward relative to the barrel 10, the space becomes larger. Since the space is relatively closed, less air enters the space, so that the negative pressure formed by the space is stronger, and the automatic unfolding effect of the garbage bag 40 is better.

[0114] In an optional embodiment, the side wall of the sleeve 20 is provided with a fixing portion 22 for fixing the garbage bag 40, so that when the sleeve 20 is driven to move away from the barrel 10, the bag opening of the garbage bag 40 is fixed on the sleeve 20. When the bag opening of the garbage bag 40 is fixed on the sleeve 20 by the fixing portion 22, the user can lift the sleeve 20 while driving the bag opening to move upward at the same time, and the bag opening can also be prevented from moving toward the bottom of the barrel 10 during use.

[0115] In an optional embodiment, the fixing portion 22 includes a plug-in hole 221, and a plurality of flexible clamping members 222 are arranged in the plug-in hole 221. When the bag opening of the garbage bag 40 is sleeved on the top edge of the sleeve 20, the bag opening is plugged into the plug-in hole 221, and the flexible clamping members 222 limit the bag opening from being pulled out. When the user plugs in the bag opening, the flexible clamping members 222 are deformed, so that the plugging process is smoother. When the flexible clamping members 222 recover from deformation, the bag opening can be limited to prevent the bag opening from being pulled out of the plug-in hole 221.

[0116] It can be understood that the fixing portion 22 can also be a clamping structure, an adhesive structure, etc., as long as it can fix the bag opening of the garbage bag 40.

[0117] In an alternative embodiment, the garbage bag 40 is placed in the barrel 10, and the bag opening is arranged at the second position of the barrel 10, when the sleeve 20 is at the second position, the sleeve 20 covers the bag opening, and the sleeve 20 covers the bag opening to hide the garbage bag 40, so that the garbage can is more beautiful, preferably the bag opening of the garbage bag 40 is sleeved at the barrel opening, and the bag opening is turned outwards to the second position, when the sleeve 20 is moved from the first position to the second position relative to the barrel 10, so that the turned-out part of the bag opening is hidden between the sleeve 20 and the barrel 10.

[0118] In an alternative embodiment, when the sleeve 20 is at the second position, the sleeve 20 limits the movement of the bag opening to the bottom of the barrel 10, so as to prevent the garbage bag 40 from sliding into the barrel 10 and causing garbage to enter the garbage bag 40, thereby polluting the garbage can.

[0119] In an alternative embodiment, the barrel 10 is provided with a anti-falling part (not shown in the figure) at the second position, and the sleeve 20 is provided with a anti-falling matching part (not shown in the figure), when the sleeve 20 is driven to move from the first position to the second position, the sleeve 20 rotates relative to the barrel 10, so that the anti-falling part and the anti-falling matching part cooperate to clamp the bag opening, the anti-falling part and the anti-falling matching part cooperate to clamp the bag opening, the fixing mode is simple and efficient, for example, the anti-falling part is a clamping block, and the anti-falling matching part is a clamping groove, the garbage bag 40 is fixed between the two by the clamping block-clamping groove cooperation mode, it can be understood that the anti-falling part and the anti-falling matching part can also cooperate by adhesion or magnetic attraction to fix the bag opening of the garbage bag 40.

[0120] In an alternative embodiment, when the sleeve 20 is at the second position, the top of the sleeve 20 is lower than the top of the barrel 10, so that when the sleeve 20 slides to the limit position relative to the barrel 10, the top of the sleeve 20 will not exceed the top of the barrel 10, on the one hand, the garbage can is more beautiful as a whole, on the other hand, it can also avoid the sleeve 20 from being separated from the second position when throwing garbage because of accidentally touching the sleeve 20.

[0121] In an alternative embodiment, the bottom of the barrel 10 is provided with a base 13 extending from the side wall of the barrel 10 towards the direction away from the barrel 10, when the sleeve 20 approaches the barrel 10, the base 13 supports the bottom of the sleeve 20, preferably the base 13 is an annular structure extending from the side wall of the barrel 10 towards the direction away from the barrel 10, the outermost circle of the annular structure extends downwards, the base 13 supports the sleeve 20 on the one hand, and on the other hand, the bottom of the barrel 10 is larger, and is more stable and reliable when placed on the ground.

[0122] In an alternative embodiment, the base 13 has a recess facing away from the barrel 10, and a suction cup and / or a counterweight are arranged in the recess. The recess is arranged to reduce the contact area between the barrel 10 and the ground, thereby reducing the friction between the barrel 10 and the ground, and facilitating the rotation of the barrel 10 away from the ground when the sleeve 20 is lifted. The counterweight is arranged to increase the weight of the barrel 10, thereby facilitating the rotation of the barrel 10 relative to the sleeve 20. The suction cup is arranged to facilitate the rotation of the sleeve 20 relative to the barrel 10.

[0123] In an alternative embodiment, a barrel cover 30 is further arranged. When the sleeve 20 is kept in a position relatively far away from the barrel 10, the barrel cover 30 is arranged outside the barrel 10 and the sleeve 20. When the sleeve 20 and the barrel 10 are in the second position, the barrel cover 30 covers the outside of the sleeve 20 and the barrel 10, so as to prevent the garbage from touching the sleeve 20 when the user is throwing garbage, thereby preventing the sleeve 20 and the barrel 10 from being separated from the second position. Meanwhile, the barrel cover 30 can also prevent the garbage from entering the guide structure 11 or the space between the sleeve 20 and the barrel 10 during use, thereby facilitating the movement of the moving part 21 and improving the overall appearance of the garbage can.

[0124] Working principle:

[0125] (1) Taking the scheme in which the guide structure 11 is arranged in the barrel 10 and the moving part 21 is arranged in the sleeve 20 as an example:

[0126] When the sleeve 20 is in the first position, the sleeve 20 is lifted upward relative to the barrel 10, thereby driving the moving part 21 to move along the first guide part 111 to abut against the first guide surface 112.
