Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 8, a trash can type cleaner 100 includes: a housing assembly 10, an inner tub 20, and a fan 30.

The inner tub 20 is used to mount or fix the garbage bag 101. As a preferred embodiment, the inner tub 20 includes: an upper tub ring 21 and a lower tub 22. The upper tub ring 21 is detachably connected to the lower tub 22. Particularly, the upper barrel ring 21 and the lower barrel 22 are connected through a snap structure, so that the disassembly and the assembly are convenient. The upper bucket ring 21 and the lower bucket body 22 clamp and fix the garbage bag 101. The inner tub 20 is detachably mounted to the outer housing assembly 10. To facilitate the user's separation of the inner tub 20 from the housing assembly 10, the trash can type cleaner 100 is provided with a handle 24. Specifically, the handle 24 is connected to the upper tub ring 21. Further, the handle 24 is rotatably connected to the upper tub ring 21. When it is desired to use the handle 24, the handle 24 is rotated to erect the handle 24 into an operative state. When the handle 24 is not used, the handle 24 can be rotated to horizontally store the handle 24.

The fan 30 is used to move an air stream to move dust into the trash bag 101. The inner tub 20 is formed with a receiving chamber 20 a.

The trash bag 101 mounted to the inner tub 20 divides the receiving chamber 20a into an upper chamber 201a and a lower chamber 202 a.

The upper chamber 201a serves as a space for the garbage bag 101 to be loaded with garbage. The lower chamber 202a serves as a space between the bottom of the trash bag 101 and the receiving chamber 20 a. When the garbage bag 101 is attached to the wall of the accommodating cavity 20a, the volume of the lower cavity 202a will be reduced to a minimum value, which may be 0. The bag expansion of the traditional garbage can type dust collector is shown in that the garbage bag floats upwards to expand under the influence of negative pressure, and the volume of an upper cavity is reduced, so that the normal garbage loading function cannot be completed.

As a specific embodiment, the inner tub 20 forms a dust suction inlet 21 a. The dust suction inlet 21a supplies dust into the dust bag 101 in the inner tub 20. The inner tub 20 forms an air suction port 21 b. The suction opening 21b sucks the air in the dust bag 101 to form a negative pressure for sucking dust from the dust suction inlet 21a into the dust bag 101. The housing assembly 10 forms a wind chamber 10 a. When the fan 30 is operated, air is extracted to generate negative pressure in the air chamber 10 a. The air suction port 21b communicates with the air chamber 10a and the upper chamber 201 a. When the blower 30 is operated, the air in the upper chamber 201a is pumped out to generate a negative pressure in the upper chamber 201a, so that the garbage can be sucked into the upper chamber 201a, i.e., the garbage bag space. In order to prevent the trash can type vacuum cleaner 100 from sucking the impurities such as dust into the air chamber 10a during operation, a filtering device is provided at the air suction hole 21b to filter the passing air. As a specific embodiment, the filtering means is a filter paper or a screen.

The shell component and/or the inner barrel body are/is provided with a dust suction inlet, an air suction opening and an air cavity. That is, the dust suction inlet can be formed by a shell component, an inner barrel body or an integral body formed by the shell component and the inner barrel body. Also, the pumping port may be formed by the outer casing member, by the inner tub member or by an integral body of the outer casing member and the inner tub member. The wind cavity can be formed by the outer shell component, the inner barrel body or the whole formed by the outer shell component and the inner barrel body.

For the traditional garbage can type dust collector, when the fan works, the garbage bag is easily sucked up due to negative pressure generated in the garbage bag, so that the bag is expanded, the space of an upper cavity is reduced, and the garbage bag is inconvenient to load goods.

The inner tub 20 is provided with a suction hole 20 b. The air suction hole 20b communicates the air chamber 10a and the lower chamber 202 a. When the blower 30 is operated, air in the lower chamber 202a is drawn from the suction holes 20 b. Because the lower cavity 202a and the outside only have one air suction hole 20b, after air is sucked from the air suction hole 20b, the air in the lower cavity 202a is reduced, and the negative pressure is gradually increased, so that a downward pulling force is applied to the garbage bag, and the garbage bag is directly attached to the cavity wall of the accommodating cavity 20 a. The garbage bag is attached to the wall of the garbage can without additionally arranging a fixing structure. When the garbage bag is attached to the wall of the accommodating cavity 20a, or when the negative pressure reaches a certain level, the air in the lower cavity 202a cannot be continuously drawn through the air suction hole 20 b. At this time, the suction force generated by the fan 30 is completely distributed to the suction opening 21b, so that stable suction force is provided during normal operation to perform dust collection operation.

In a preferred embodiment, the suction holes 20b are provided at the bottom of the inner tub 20. Specifically, the air intake hole 20b is provided directly above the fan 30. Helping to quickly complete the extraction of air from the lower chamber 202 a.

As a preferred embodiment, the trash can vacuum cleaner 100 further includes a cover 23 for closing the suction hole 20 b.
