The structure is simple and rational in terms of design; the fan (3) is provided in the dust suction box (2), such that a dust suction path is changed into a one-way path without needing to turn back; the suction force is large, and the dust suction effect is good; moreover, the air outlet is provided in a side wall of the dust suction box, thereby reducing the risk of the inside of the host (1) being polluted by dust; and only one butt-joint is provided between the host (1) and the dust suction box (2), such that the sealing difficulty is reduced, and the dust suction box (2) and the host (1) are connected more conveniently, thus, the sealing is more reliable.

Description

Sweeper

technical field

The present invention relates to a sweeper.

Background technique

The existing sweeper includes a main unit and a vacuum box. The fan is located in the main body, and the dust suction port is located on the bottom surface of the main unit. The dust cavity in the box, so that when the fan is started, the air flow enters the vacuum box through the suction port, and then returns to the main machine, and then exits the main body, so that there are two interfaces between the vacuum box and the main machine, once the sealing effect is not good, The fan cannot absorb dust, the adsorption force is greatly reduced, and the air flow is turned back, which also greatly reduces the dust suction effect.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a sweeper with a short and smooth dust suction path and few sealing openings.

The object of the present invention is achieved in this way.

A sweeper includes a main unit, a vacuum box and a fan. An electric control device and a dust suction channel are arranged in the main body. The dust port is set on the wall of the dust chamber corresponding to the dust chamber, and the fan is set in the fan chamber. When the air flow in the dust chamber enters the fan chamber, it must first pass through the filter device. The wall of the dust chamber corresponding to the fan chamber is provided with an exhaust hole. The air outlet of the fan is communicated with the air outlet; the vacuum box is also provided with a power-taking interface, and the power-taking interface is electrically connected with the fan. When the vacuum box and the host are connected together, the power-taking interface is connected to the electric control device. The electrical connection is realized, the dust inlet is connected with the outlet of the dust suction channel. When the fan is started, the air flow enters the dust chamber from the dust suction channel through the dust inlet, and then enters the fan after passing through the filter device. hole to discharge the dust box.

The above technical solution can be further improved as follows.

When the dust inlet is in communication with the outlet of the dust suction channel, the dust inlet and the outlet of the dust suction channel are in sealing cooperation.

The dust suction box includes a door body and a box body, one side of the door body is rotatably connected with the box body, a locking device is arranged between the other side of the door body and the box body, and the dust inlet is arranged on the door body.

The connection between the power taking interface and the electric control device is an elastic connection.

The structure design of the invention is simple and reasonable, the fan is arranged in the vacuum box, the vacuum path becomes one-way, no need to turn back, the suction force is large, and the vacuum effect is good, and the air outlet is arranged on the side wall of the vacuum box, reducing the number of main engines. The risk of being polluted by dust in the body, there is only one interface between the host and the vacuum box, the sealing difficulty is reduced, the disassembly and assembly between the vacuum box and the host is more convenient, and the sealing is more reliable.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

Embodiments, in conjunction with the accompanying drawings, a sweeper, comprising a main engine 1, a vacuum box 2 and a fan 3, an electric control device and a dust suction channel 10 are arranged in the main body, and the electric control device includes a circuit board, a main machine walking drive device, various Such sensors, etc., since this part of the structure is in the prior art, it will not be described again. The dust suction box 2 is provided with a dust inlet 4, and the dust chamber 5 and the fan chamber 6 are separated into the dust chamber. The air flow in the dust chamber needs to pass through the filter device 7 before entering the fan chamber. The dust box wall corresponding to the fan chamber is provided with an exhaust hole 8 , and the exhaust port of the fan 3 communicates with the exhaust hole 8 . Garbage remains in the dust chamber.

The dust collecting box is also provided with a power taking interface 9, which is electrically connected with the fan 3. When the dust collecting box 2 is connected with the host 1, the dust inlet and the outlet of the dust suction channel are connected and connected. Form a tight fit. At the same time, the power-taking interface is electrically connected to the electric control device, and the connection between the power-taking interface and the electric control device can be an elastic connection. For example, the conductive terminal on the power-taking interface itself has elasticity. The port 4 enters the dust chamber 5, and then enters the fan 3 after passing through the filter device 7, and is discharged from the dust box 2 from the exhaust port of the fan through the exhaust hole 8.

The above-mentioned dust collecting box 2 can also be divided into two parts, including a door body 20 and a box body 21 respectively, one side of the door body is rotatably connected with the box body, and a locking device is arranged between the other side of the door body and the box body, and dust intake The mouth is arranged on the door body, the motor cavity is located in the box body, and the dust cavity is respectively arranged in the door body and the box body. The locking device is an elastic switch. When the locking device is opened, the door body and the box body are separated, which is convenient for garbage dumping.
