The trash bag is set on the first opening of the trash can, and a sealed cavity is formed between the trash bag and the main body, the exhaust device exhausts the air in the sealed cavity outward, and the outside air enters the trash bag, so that the trash bag as a whole is close to and fits with the inner wall of the main body under the action of air pressure, so that the installation of the trash bag is more convenient, and the exhaust device is driven by a mechanical structure, which is lower in cost than motor drive.

[0006] Preferably, the exhaust device includes a release mechanism, which can disconnect the mechanical conduction between the switch, the gear mechanism and the exhauster, so that the exhauster is not affected by the active state of the switch or the gear mechanism and can continuously rotate to exhaust air outward. The switch generally reciprocates, and when the switch is reset, it is easy to drive the gear mechanism to reversely operate, so that the exhauster stops rotating or reversely rotates to affect exhaust.

[0023] The following describes the implementation methods of the present invention in detail in conjunction with the accompanying drawings, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Certain words are used in the present utility model to refer to specific components. Those skilled in the art should understand that this specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as the criterion for distinction. It should be noted that, unless otherwise specified, when a component is described as "provided with" or "provided on" or "provided on" another component, it can mean that it is directly provided with or directly provided on another component, or there can also be a central component, and it can be an integral structure or a split structure. When a component is described as "connected to" another component, it can be directly connected or connected through a central component, and it can be an integral connection, a split connection, or a contact and matching relationship. When a component is described as "provided on another component", it does not mean that the component must be located above or on the upper part of another component, but can also be located in other positions. The terms "upper", "lower", "left", "right", "high", "low" and similar expressions used herein are based on the normal placement state of the product, and are only for the purpose of convenience of explanation. The term "multiple" used herein refers to two or more numbers. The terms "vertical", "horizontal" and the like as used herein refer to a substantially vertical or substantially horizontal state within a reasonable error range and do not necessarily have to be very precise.

[0025] like Figure 1-7 A trash can comprises a main body 1, a first opening 2 is provided on the top of the main body 1, the top of the trash bag is hung at the first opening 2, and the bottom enters the main body 1 from the first opening 2, an exhaust device 3 is provided on the main body 1, the exhaust device 3 draws out the air in the main body 1, so that the trash bag as a whole expands toward the direction close to the side wall of the main body 1, the exhaust device 3 comprises an exhaust fan 4, a gear mechanism 5 and a switch 6, the gear mechanism 5 is connected to the exhaust fan 4 and the switch 6 respectively, the switch 6 moves to drive the gear mechanism 5 to operate, so as to drive the exhaust fan 4 to rotate and exhaust outward, and when the switch 6 is reset, the exhaust fan 4 continues to rotate in the same direction to exhaust.

[0026] The switch 6 is rotatably or slidably installed on the main body 1, and the gear mechanism 5 accelerates the movement of the switch 6 to the exhaust fan 4 so that the exhaust fan 4 can rotate at a high speed to exhaust. Since the path of a single rotation or sliding of the switch 6 during the driving activity is limited, it needs to be reset to the initial position after completing one activity to prepare for the second driving activity. When the switch 6 is reset, it is easy to drive the gear mechanism 5 to operate in the opposite direction, thereby affecting the rotation of the exhaust fan 4. For example, the exhaust fan 4 stops rotating or rotates in the opposite direction, so that the exhaust stops or the exhaust volume is reduced. In order to reduce the impact of the reset activity of the switch 6 on the exhaust fan 4, a one-way gear can be set inside the gear mechanism 5 or between the gear mechanism 5 and the switch 6 or between the gear mechanism 5 and the exhaust fan 4. When the switch 6 is driven, the gear mechanism 5 and the exhaust fan 4 operate normally. When the switch 6 is reset, the one-way gear no longer transmits the activity to the downstream when the activity is transmitted to the one-way gear position, and the exhaust fan 4 can continue to rotate in the same direction to exhaust. Of course, other methods can also be used to reduce the impact of the reset activity of the switch 6 on the exhaust fan 4.

[0027] In this embodiment, this is achieved by providing a loosening mechanism in the exhaust device 3. The loosening mechanism can disconnect the mechanical conduction between the switch 6, the gear mechanism 5 and the exhaust fan 4, so that the exhaust fan 4 is not affected by the activity state of the switch 6 or the gear mechanism 5 and can continuously rotate to exhaust air outwards.

[0028] Specifically, the loosening mechanism is configured as a loosening gear 7, and a first gear 8 and a second gear 9 are respectively provided upstream and downstream of the loosening gear 7. A loosening groove 11 is provided on the gear box 10, and the loosening gear 7 is movably installed in the loosening groove 11. The loosening gear 7 can automatically move to a different position through different moving directions of the switch 6 to change the meshing state in the gear mechanism 5.

[0029] Preferably, the release groove 11 is in the shape of an elongated strip or an arc as a whole, and the length direction of the release groove 11 is arranged along the rotation direction of the first gear 8, or the arc shape of the release groove 11 is part of the concentric circle of the first gear 8. When the first gear 8 rotates, its teeth push the release gear 7, so that the release gear 7 is forced to rotate and move along the release groove 11. According to the different rotation directions of the first gear 8, the release gear 7 can be moved to different positions to change the meshing state with the second gear 9. The process switches automatically, and there is no need to separately set up a mechanism for controlling the on and off of the gear mechanism 5, which is simpler to use.

[0030] The switch 6 is provided with a rack or gear that cooperates with the gear mechanism 5. The loosening gear 7 moves to different positions in the loosening groove 11 and is always meshed with the upstream first gear 8. The switch 6 is driven to move, and the first gear 8 rotates in a first direction to drive the loosening gear 7 to rotate and move to a position meshed with the second gear 9, so as to drive the second gear 9 and the exhaust fan 4 to rotate. The switch 6 is reset, and the second gear 9 rotates in the opposite second direction to drive the loosening gear 7 to rotate and move to a position separated from the second gear 9, and the exhaust fan 4 continues to rotate by inertia.

[0031] like Figure 4-6 When the switch 6 is in the initial position, the loosening gear 7 is separated from the second gear 9, the switch 6 moves downward, and the first gear 8 drives the loosening gear 7 to rotate and move to a position meshing with the second gear 9, until the switch 6 moves to the lowermost end, and the loosening gear 7 is still meshed with the second gear 9; when the switch 6 moves upward, the first gear 8 rotates in the opposite direction, driving the loosening gear 7 to rotate and move in the opposite direction and separate from the second gear 9.

[0032] In this embodiment, the switch 6 is slidably mounted on the main body 1, and the lower end of the switch 6 is movably connected to a rocker arm 12. The other end of the rocker arm 12 is rotatably connected to the gear box 10. The rocker arm 12 is provided with teeth 13 that mesh with the gear mechanism 5 for transmission. The sliding of the switch 6 drives the rocker arm 12 to rotate, and the teeth 13 on the rocker arm 12 drives the gear mechanism 5 to operate.

[0033] like Figure 4 and 5 In order to avoid jamming of the switch 6 and the rocker arm 12 during relative movement, a slide groove 14 is provided on the switch 6. The rocker arm 12 is connected to the switch 6 via a connecting shaft. When the switch 6 and the rocker arm 12 move relative to each other, the connecting shaft moves along the slide groove 14 to adjust the matching position.

[0034] Preferably, both the rocker arm 12 and the main body 1 are provided with hanging ears 15, and a tension spring 16 is provided between the two hanging ears 15, and the tension spring 16 drives the switch 6 to automatically reset.

[0035] In the above embodiment, the exhaust device 3 also includes an exhaust box 17, and the exhaust fan 4, the gear mechanism 5, the switch 6 and the loosening mechanism are all installed on the exhaust box 17 to form a whole. The exhaust device 3 is detachably installed on the inner side of the main body 1 as a whole. During production and assembly, the exhaust fan 4, the gear mechanism 5, the switch 6 and the loosening mechanism are first installed on the exhaust box 17 to form an integral module, and then the integral module is installed on the main body 1. Since the main body 1 is barrel-shaped and the exhaust device 3 is generally installed at the lower inner side of the main body 1, if the various components of the exhaust device 3 are separately installed on the main body 1, the installation efficiency is low. At the same time, consumers can also remove the exhaust device 3 for cleaning or maintenance according to their own needs, which is more convenient to use.

[0036] An air inlet 18 is provided on the exhaust box 17, and an exhaust hole 19 is provided on the side wall or bottom wall of the main body 1. The air in the main body 1 is discharged outward through the air inlet 18, the exhaust device 4 and the air outlet. Preferably, the exhaust hole 19 is arranged on the lower side or bottom of the main body 1 to reduce the impact of the odor in the main body 1 on the user.

[0037] In this embodiment, a third opening 20 is provided on the side wall of the main body 1, a baffle 21 is provided on the third opening 20, and the switch 6 extends from between the third opening 20 and the baffle 21. The baffle 21 and the switch 6 block the third opening 20 to reduce the amount of air entering the main body 1 from the third opening 20.

[0038] Preferably, the switch 6 includes a control part 22 and a matching part 23, the control part 22 is installed on the third opening 20, and the matching part 23 is installed on the exhaust box 17. When the exhaust box 17 is installed on the main body 1, the control part 22 and the matching part 23 are plugged and fixed to form a whole.

[0039] Preferably, the exhaust fan 4 can be configured as a fan, a wind wheel or a rotor with blades installed, etc., and the exhaust fan 4 is provided with gears that cooperate with the gear mechanism 5 for transmission.

[0040] In the above embodiment, the main body 1 can be set as an open trash can or an openable trash can, and a cover ring for fixing the trash bag or a fixing member 24 for clamping the trash bag is provided at the position of the first opening 2. The openable trash can can also be set as a double-cover structure, such as an upper cover 25 covering the first opening 2, and a second opening 26 is also provided on the upper cover 25, and an openable top cover 27 is provided on the second opening 26. The trash bag is put on the first opening 2, and the top cover 27 is opened for daily use. At the same time, the switch 6 structure of the top cover 27 can also be set as a manual press to open the cover structure or a foot-operated cover to open the cover structure.

[0041] like Figure 7 The switch 6 can also be set on the pedal 28 for stepping on, or the switch 6 can be set as the pedal 28, and exhaust can be achieved by stepping on the pedal 28.
