Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a trash can with an air-pumping bag, and in particular to a trash can with a drawstring type air-pumping bag. Background Art

[0002] Trash cans are common containers for holding garbage and waste in homes or offices. They are usually covered with garbage bags. Some trash cans are equipped with exhaust devices to ensure that the garbage bags fit the inner walls.

[0003] For example, the patent with authorization announcement number CN221050592U provides a garbage bag suction type garbage can, which includes a garbage can body with an inner cavity, an air pump connected to the outside of the garbage can body, and a press-fit cover rotatably installed on the garbage can body. The top of the air pump is slidably connected to a connecting rod extending to the inner cavity, the top of the connecting rod is fixedly connected to a pressure plate, the bottom of the connecting rod is fixedly connected to a piston, the piston slides in the inner cavity of the air pump, and a plurality of springs are fixedly connected between the piston and the inner cavity of the air pump.

[0004] However, the vacuum pump is directly connected to the body of the trash can. The setting of the vacuum pump increases the weight of the trash can itself, which increases the friction between the trash can and the ground when the trash can is pushed to slide on the ground.

[0005] When putting the bag into the trash can, you need to press the pressure plate in advance to compress the spring, then put the garbage bag into the inner cavity of the inner barrel, and turn the pressing cover so that the pressing cover can tightly press the garbage bag and the sealing ring. Then release the pressure plate and use the rebound force of the spring to drive the piston to extract the air in the trash can body, so that the garbage bag is adsorbed in the inner cavity of the trash can body.

[0006] However, the trash can needs to be operated before and after the garbage bag is put on, which makes the operation of adsorbing the garbage bag on the inner wall of the trash can more cumbersome and complicated, and the operation of bagging and pumping air is more inconvenient.

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0031] This embodiment mainly describes a trash can with a drawstring type vacuum bag that can effectively reduce the weight of the trash can itself and has a simple and convenient bagging and vacuuming operation. The details are as follows:

[0032] like Figure 1-5 As shown, the trash can with a drawstring type air-suction bag comprises a barrel body 1 and an air-suction device 001 which is detachably plugged into the barrel body 1. In this embodiment, an air-suction port 11 is provided on the barrel body 1, and the air-suction device 001 comprises a shell 2, an air-suction pipe 21 which can be inserted into the air-suction port 11 is provided on the shell 2, and a plurality of air outlet holes 22 are provided on the shell 2. A turntable 3, a driving member 6, an active tooth 7, a driven tooth and a radial impeller 9 are rotatably installed in the shell 2, and a drawstring 4 is wound on the turntable 3. The turntable 3 is connected to a coil spring (the coil spring is not shown in the drawings of the specification). The turntable 3 can drive the driving member 6 to rotate, and the driving member 6 can drive the active tooth 7. The active tooth 7 engages the driven tooth to rotate, and the driven tooth engages the radial impeller 9 to rotate. The radial impeller 9 takes in air axially and discharges air radially.

[0033] The garbage bag is placed in the barrel body 1, and the exhaust device 001 is inserted into the exhaust port 11 through the exhaust pipe 21. By pulling the pull rope 4, the pull rope 4 can drive the turntable 3 to rotate, and the turntable 3 is driven by the driving member 6, the active gear 7 and the driven gear to make the radial impeller 9 rotate forward, thereby realizing the exhaust work in the barrel body 1. When the force of pulling the pull rope 4 is withdrawn, the winding spring will cause the turntable 3 to reverse, and the turntable 3 will cause the pull rope 4 to rewind on the turntable 3.

[0034] Preferably, the conventional setting of the radial impeller 6 will result in a strong wind force during forward rotation and a weak wind force during reverse rotation. However, no matter whether the radial impeller 6 rotates forward or reversely, the radial impeller 6 can perform air extraction work in the barrel body 1.

[0035] In order to ensure the stability of the exhaust pipe 21 when inserted into the exhaust port 11, a protruding edge 12 is provided on the barrel body 1. The edge 12 is located at the exhaust port 11, so that the length of the exhaust port 11 becomes larger and the contact area with the outer wall of the exhaust pipe 21 is increased.

[0036] In this application, the barrel body 1 and the vacuum device 001 are detachably installed, which can effectively reduce the weight of the barrel body 1 itself, facilitate the daily movement of the barrel body 1 for use, and reduce friction with the ground; at the same time, the pull rope 4 of the vacuum device 001 is designed so that the vacuuming and bagging operation can be achieved by pulling the pull rope 4, and the reeling of the pull rope 4 is automatically achieved by the winding spring, making the bagging and vacuuming operation simple and convenient.

[0037] like Figure 3-5 As shown, the housing 2 includes a main housing 2a, a cover 2b, a transmission housing 2c and a bottom plate 2d. The main housing 2a is provided with a driving cavity 23, the turntable 3 and the driving member 6 are arranged in the driving cavity 23 for rotational connection, the cover 2b is fixedly connected to the main housing 2a and restricts the turntable 3 and the driving member 6 from being separated from the driving cavity 23, the transmission housing 2c is fixedly installed in the main housing 2a, and a transmission cavity 24 is formed between the transmission housing 2c and the main housing 2a, and the driving gear 7 and the driven gear are rotatably installed in the transmission cavity 2 4, and the bottom plate 2d is fixedly connected to the main shell 2a, a working chamber 25 is formed between the bottom plate 2d and the main shell 2a, the transmission shell 2c is located between the main shell 2a and the bottom plate 2d, the transmission shell 2c separates the transmission chamber 24 and the working chamber 25, the radial impeller 9 is rotatably installed in the working chamber 25, preferably, the air outlet 22 is opened on the main shell 2a, the air outlet 22 connects the working chamber 25 or the working chamber 25 and the transmission chamber 24, and the exhaust pipe 21 is provided on the bottom plate 2d.

[0038] The transmission housing 2c and the main housing 2a, and the bottom plate 2d and the main housing can be fixedly connected by screws, and a support leg 2d1 is provided on the bottom plate 2d to support the transmission housing 2c.

[0039] In this embodiment, a plurality of insertion holes 26 are provided in the transmission chamber 24, and a plurality of insertion posts 2b1 are provided on the transmission chamber 24 for one-to-one interference fit with the insertion holes 26. A working opening 27 is provided on the cover 2b and the wall of the transmission chamber 24, and the pull rope 4 wound on the turntable 3 extends out of the drive chamber 23 from the working opening 27.

[0040] To prevent the pull rope 4 from being completely retracted into the drive cavity 23 , a pull ring 5 is connected to the end of the pull rope 4 exposed outside the drive cavity 23 . The pull ring 5 is larger than the size of the active opening, which can prevent the pull rope 4 from being completely rolled into the drive cavity 23 .

[0041] The cover 2b is provided with a connecting post 2b2 inserted into the turntable 3, and a coil spring is connected to the inner wall of the turntable 3 and the connecting post 2b2.

[0042] In order to facilitate the turntable 3 to drive the driving member 6 to rotate, the driving member 6 is provided with a plurality of pins 61 that are interference-fitted with the turntable 3, and the driving member 6 is provided with a driving portion 62 that is inserted into the transmission cavity 24, and the active tooth 7 is provided with a slot 71 for the driving portion 62 to be inserted. The non-circular structure between the driving portion 62 and the slot 71 cooperates, so that the turntable 3 can drive the driving member 6 to rotate.

[0043] The radial impeller 9 is provided with an engaging portion 91 inserted into the transmission cavity 24. In this embodiment, the driven teeth include dynamic driven teeth 8a and positioning driven teeth 8b, wherein the positioning driven teeth 8b engage the engaging portion 91 of the radial impeller 9, and a slide groove 2c1 is provided on the transmission housing 2c. The dynamic driven teeth 8a rotate and slide to connect the slide groove 2c1, and the dynamic driven teeth 8a always engage with the driving teeth 7, pulling the pull rope 4, and the pull rope 4 drives the driving teeth 7 to rotate forward through the turntable 3 and the driving member 6, and the driving teeth 7 engage with the dynamic driven teeth 8a to rotate, and slide along the slide groove 2c1 to approach and engage with the positioning driven teeth 8b, thereby realizing the meshing transmission between the driving teeth 7, the dynamic driven teeth 8a, the positioning driven teeth 8b and the engaging portion 91 of the radial impeller 9.

[0044] When the turntable 3 is reversed by the torsion spring, the turntable 3 drives the active tooth 7 to reverse through the driving member 6. The active tooth 7 engages with the dynamic driven tooth 8a to rotate and slides along the slide groove 2c1 away from the positioning driven tooth 8b, so that the engagement between the dynamic driven tooth 8a and the positioning driven tooth 8b is disengaged. When the pull rope 4 is wound back onto the turntable 3 under the drive of the reverse rotation of the turntable 3, the active tooth 7 cannot drive the radial impeller 9 to rotate through the positioning driven tooth 8b and the dynamic driven tooth 8a.
