In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1-Figure 7 The automatic paving mechanism of the garbage bag comprises a barrel body 40, a volute fan 41 is arranged inside the barrel body 40, a barrel body air outlet 42 is arranged at the bottom, and the air outlet of the volute fan 41 faces the barrel body air outlet 42.

[0027] The present embodiment utilizes the volute fan 41 to extract the air inside the barrel body 40, so that a negative pressure state is formed inside the barrel body 40, so that the garbage bag can be automatically laid inside the barrel body 40. At the same time, the air extracted by the volute fan 41 is directly discharged toward the barrel body air outlet 42 at the bottom of the barrel body 40. This not only avoids the problem that the volute fan 41 of the prior art is set on the top of the garbage can, which makes the garbage can easily tip over when in use, so as to improve the stability of the garbage bag. At the same time, since the barrel body air outlet 42 is set at the bottom of the barrel body 40, it can avoid the problem that the air outlet is set on the side wall of the garbage can and the garbage can is placed against the wall to cause air outlet obstruction, so that the garbage can can be placed at any position at will to reduce space occupancy. In addition, the volute fan 41 is silent and efficient when working, and can extract the air inside the barrel body 40 in a relatively short time, thereby completing the automatic and rapid laying of the garbage bag, so as to improve the user experience.

[0028] As a preferred solution of this embodiment, it may also have the following additional technical features:

[0029] The fan axis A of the volute fan 41 and the air outlet axis B of the barrel air outlet 42 are perpendicular, parallel, or form an angle with each other.

[0030] In this embodiment, the fan axis A and the air outlet axis B are perpendicular to each other, that is, the air in the barrel body 40 is laterally drawn out by the volute fan 41 and then discharged vertically through the barrel body air outlet 42.

[0031] An air guide hood 43 is provided on the air outlet of the volute fan 41, and the air guide hood 43 guides the air in the direction of the barrel air outlet 42, so that the air drawn out by the volute fan 41 can be guided to the barrel air outlet 42 through the air guide hood 43, which can not only speed up the flow of air, but also ensure that the air in the barrel 40 is discharged through the barrel air outlet 42.

[0032] The air guide cover 43 is in a trumpet shape or a straight cylinder shape.

[0033] The air inlet of the air guide cover 43 is fixedly connected to the air outlet of the volute fan 41 , and the air outlet of the air guide cover 43 faces the barrel body air outlet 42 , and is spaced apart from the barrel body air outlet 42 , or is covered on the barrel body air outlet 42 .

[0034] In the present embodiment, the air guide cover 43 is trumpet-shaped, the small port of the air guide cover 43 is the air inlet and is fixedly connected to the air outlet of the volute fan 41, the large port of the air guide cover 43 is the air outlet and faces the barrel body air outlet 42, and at the same time, the air outlet of the air guide cover 43 is spaced apart from the barrel body air outlet 42 to reduce the dependence of the air guide cover 43 on the barrel body air outlet 42, and the bottleneck phenomenon caused by the sudden reduction in the size of the barrel body air outlet 42 during the air flowing toward the barrel body air outlet 42, thereby ensuring that the air inside the barrel body 40 can be discharged smoothly.

[0035] The bottom of the barrel body 40 is also provided with supporting feet 44, and a wind dispersion area is formed by the supporting feet 44, whereby after the barrel body 40 is placed, air can be discharged between the barrel body air outlet 42 and the placement surface through the wind dispersion area.

[0036] A partition 45 is provided inside the barrel body 40, and the partition 45 separates the inside of the barrel body 40 into a garbage bag chamber 46 and an electric control chamber 47. The volute fan 41 is fixedly set on the partition 45 and is located in the electric control chamber 47. The partition 45 is also provided with a grille 48 corresponding to the air inlet of the volute fan 41.

[0037] In this embodiment, the setting of the partition 45 can prevent the garbage bag from affecting the electrical components inside the electrical control chamber 47, so as to ensure that the electrical components inside the electrical control chamber 47 can work stably. The air inlet of the volute fan 41 draws air from the inside of the barrel body 40 through the grille 48.

[0038] The inner wall of the barrel body 40 is provided with a positioning groove 49 , and the partition plate 45 is positioned on the positioning groove 49 and fixed to the barrel body 40 by fasteners, snap-fitting, pasting, or embedding.

The bag outlet, the cover opening 52 and the barrel mouth 50 are connected to each other.

[0041] In this embodiment, the user can store the rolled garbage bags through the bag slot 53 so that the garbage bags can be automatically replaced and laid, and the bag slot cover 54 can protect the stored rolled garbage bags.

[0042] When the volute fan 41 is working, the air inside the barrel body 40 is extracted, so that a negative pressure state is formed inside the barrel body 40. At this time, under the action of atmospheric pressure, the garbage bag is extracted from the bag outlet and passes through the cover 52 and the barrel mouth 50 in sequence to reach the inside of the barrel body 40, thereby completing the automatic laying of the garbage bag.

[0043] A top cover 55 is also provided on the cover body 51 . The top cover 55 is flipped and provided on the cover body 51 , and opens and closes the barrel opening 50 and the cover opening 52 when flipped.

[0044] When in use, the user only needs to flip open the top cover 55 to throw garbage onto the garbage bag in the barrel body 40. When the top cover 55 is flipped closed, it can cover the barrel mouth 50, the cover mouth 52 and the garbage bag.

[0045] The flipping direction of the cover body 51 is the same as or different from the flipping direction of the top cover 55 .

[0046] In this embodiment, the flipping direction of the cover body 51 is the same as the flipping direction of the top cover 55. At the same time, the position of the volute fan 41 is on the same side as the flipping position of the cover body 51 and the top cover 55. The volute fan 41 is arranged at the bottom of the side close to the barrel body 40, which can lower the overall center of gravity of the barrel body 40 and further prevent the trash can from tipping over when the cover body 51 and the top cover 55 are flipped.
