Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a vacuum trash can, and in particular to a trash can capable of manually pumping out air and lowering bags. Background Art

[0002] Trash can is a kind of container specially holding garbage and waste. In order to avoid frequent cleaning of the trash can due to dirt, most of them will use garbage bags in the trash can to facilitate the extraction of the garbage bags for garbage disposal.

[0003] Due to the material of the garbage bag, when the user puts the garbage bag in the trash can, static electricity will be generated due to friction between the garbage bag and the trash bag, causing the garbage bag to bulge in the trash can when the user puts the trash can on the garbage bag. After the garbage is thrown in, the edge of the garbage bag on the trash can may fall into the trash can, causing the garbage bag to leak on the trash can, causing the garbage to directly enter the trash can from the leak.

[0004] Most vacuum trash cans, such as the patent with authorization announcement number CN218056855U, provide a garbage bag lowering device, including a motor that works when powered, and a runoff fan blade that can extract air from the trash can by driving the motor. When the garbage bag is put on the trash can, the motor is driven to work, and the garbage bag can be lowered and fits against the inner wall of the trash can.

[0005] However, the installation of the motor leads to a significant increase in the cost of the trash can and the weight of the trash can. In addition, the motor is usually powered by a battery power supply or an external household electricity. The battery power supply needs to be replaced or charged frequently due to its limited power, which makes it inconvenient to use. In addition, when connecting to an external household electricity, a conductive wire is required, which causes inconvenience in cleaning the floor in daily life. Utility Model Content

[0028] 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.

[0029] 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.

[0030] This embodiment mainly describes a hand-cranked vacuum bag-discharging trash can that can effectively reduce costs and improve convenience, as follows:

[0031] like Figure 1-5 As shown, the trash can that can be manually pumped out of the bag comprises a barrel body 1 and an air extraction device 001 that is detachably plugged into the barrel body 1. In this embodiment, an air extraction port 11 is provided on the barrel body 1, and the air extraction device 001 comprises a shell body 2, a plug-in tube 21 that can be inserted into the air extraction port 11 is provided on the shell body 2, and a plurality of exhaust ports 22 are provided on the shell body 2. A rocker arm 3 is rotatably mounted on the outside of the shell body 2, and a driving tooth 4, a driven tooth 5 and a radial impeller 6 are rotatably mounted on the inside of the shell body 2. By driving the rocker arm 3 to rotate, the rocker arm 3 can drive the driving tooth 4 to rotate, the driving tooth 4 engages the driven tooth 5 to rotate, and the driven tooth 5 engages the radial impeller 6 to rotate.

[0032] When the garbage bag is put into the barrel body 1, the radial impeller 6 is driven to rotate by rotating the rocker arm 3. The radial impeller 6 draws out the air between the plastic bag and the inner wall of the barrel body 2 through axial air intake and radial air outlet, thereby reducing the air pressure between the plastic bag and the inner wall of the barrel body 2, so that the garbage bag sticks to the inner wall of the barrel body 1.

[0033] Preferably, the conventional setting of the radial impeller 6 will result in strong wind force during forward rotation and weak wind force during reverse rotation. By increasing the rotation speed of the rocker arm 3 or changing the gear ratio of the meshing gear 5, the radial impeller 6 can be rotated quickly. By increasing the rotation speed of the radial impeller 6, the defect of weak wind force during reverse rotation can be compensated, so that the rocker arm 3 can perform air extraction when rotating forward or reversely.

[0034] In order to ensure the stability of the plug-in tube 21 when inserted into the air outlet 11, a protruding edge 12 is provided on the barrel body 1. The edge 12 is arranged at the air outlet 11, so that the length of the air outlet 11 becomes larger and the contact area with the outer wall of the plug-in tube 21 is increased.

[0035] A small ring gear 61 is provided on the radial impeller 6, and a coaxially arranged ring gear 1 51 and a ring gear 2 52 are provided on the driven tooth 5. The outer diameter of the ring gear 1 51 is smaller than the outer diameter of the ring gear 2 52, and the outer diameter of the driving tooth 4 is larger than the outer diameter of the ring gear 1 51, and the outer diameter of the small ring gear 61 is smaller than the outer diameter of the ring gear 2 52. In the following description, the prefixes "first", "second" and "third" are used to distinguish the driven tooth 5.

[0036] The driving tooth 4 meshes with the ring gear 1 51 of the first driven tooth 5a, the ring gear 2 52 of the first driven tooth 5a meshes with the ring gear 1 51 of the second driven tooth 5b, the ring gear 2 52 of the second driven tooth 5b meshes with the ring gear 1 51 of the third driven tooth 5c, and the ring gear 2 52 of the third driven tooth 5c meshes with the small ring gear 61 of the radial impeller 6. Through the step-by-step transmission of the driven teeth 5, the rotational speed of the radial impeller 6 is much greater than the rotational speed of the driving tooth 4, that is, the rocker arm 3.

[0037] In other embodiments, the driven tooth 5 may not be provided in the housing 2, and the driving tooth 4 directly engages with the small ring gear 61 of the radial impeller 6. In this case, the outer diameter of the driving tooth 4 may be larger than the outer diameter of the small ring gear 61; or only one driven tooth 5 is provided in the housing 2, and the ring gear 1 51 of the driven tooth 5 engages with the driving tooth 4, and the ring gear 2 52 engages with the small ring gear 61 of the radial impeller 6.

[0038] A rotating shaft 1 7 and a rotating shaft 2 8 are installed in the housing 2 , wherein the driving tooth 4 , the second driven tooth 5 b and the radial impeller 6 are rotatably mounted on the rotating shaft 1 7 , and the first driven tooth 5 a and the third driven tooth 5 c are rotatably mounted on the rotating shaft 2 8 .

[0039] In this application, the rocker arm 3, the driving gear 4 and the radial impeller 6 are provided to effectively reduce the cost of the trash can, and there is no need to consider the power supply problem when vacuuming the lower bag in the trash can, thereby improving the convenience of use.

[0040] like Figure 4-5 As shown, the housing 2 includes a main housing 2a, a transmission housing 2b and a base plate 2c. The transmission housing 2b and the base plate 2c are fixedly connected to the main housing 2a, and the transmission housing 2b is located between the main housing 2a and the base plate 2c. The transmission housing 2b is separated from the main housing 2a to form a transmission chamber 24 and a working chamber 25. The driving teeth 4 and the driven teeth 5 are both rotatably set in the transmission chamber 24, and the radial impeller 6 is rotatably installed in the working chamber 25, but the small gear ring 61 of the radial impeller 6 is inserted into the transmission chamber 24 for meshing.

[0041] Preferably, a plurality of exhaust ports 22 on the shell 2 are opened on the main shell 2a, the exhaust ports 22 are connected to the working chamber 25, or connected to the working chamber 25 and the transmission chamber 24, and the plug-in tube 21 on the shell 2 is set on the bottom plate 2c.

[0042] The housing 2 is provided with a connecting pipe 23 connected to the transmission chamber 24, and the driving gear 4 is provided with a plug-in portion 41, which is inserted into the connecting pipe 23. The rocker arm 3 is provided with an annular groove 31 inserted into the connecting pipe 23, and a socket 32 ​​plugged into the plug-in portion 41. The non-circular structure between the socket 32 ​​and the plug-in portion 41 is matched, so that the rocker arm 3 can drive the driving gear 4 to rotate.

[0043] In order to facilitate the driving of the rocker arm 3 to rotate, a rocker arm 33 is connected to the outer wall of the annular groove 31 of the rocker arm 3, and an operating part 34 is provided on the end of the rocker arm 33 away from the annular groove 31. The operating part 34 is protruded on the rocker arm 33, and the protruding direction of the operating part 34 is opposite to the opening direction of the notch of the annular groove 31.

[0044] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.
