In the first state, the second cleaning module 500 is mounted to the dust cup module 200, so that a large area such as a floor can be cleaned using the second cleaning module 500. Therefore, the cleaning equipment can have two cleaning modes, different cleaning requirements can be met, and the application range is wider.

In the above embodiment, the second cleaning module 500 is used to view the suction cleaning module 400, and the cleaning apparatus further includes the second cleaning module 500, where the second cleaning module 500 is detachably mounted on the dust cup module 200, and the suction cleaning module 400 has a first state in which it is stopped and a second state in which it can operate. In the first state, the second cleaning module 500 is mounted to the dirt cup module 200, the suction cleaning module 400 is received between the dirt cup module 200 and the second cleaning module 500, and the second cleaning module 500 is in fluid communication with the dirt cup module 200; in the second state, the second cleaning module 500 is separated from the dirt cup module 200, and fluid communication between the second cleaning module 500 and the dirt cup module 200 is broken.

Referring to fig. 1, 3, 7 and 9, further, in some embodiments, the second cleaning module 500 has an air outlet pipe 540, the air outlet pipe 540 has a second airflow cavity 541, the second airflow cavity 541 has a third air outlet 5411, the second cleaning module 500 further has a third air inlet 511 connected to the second airflow cavity 541, and in the first state, the air outlet pipe 540 extends into the extension pipe 220, so that the third air outlet 5411 is connected to the first air inlet 221.

Specifically, in view of the drawing, the air outlet pipe 540 is located at the top end region of the second cleaning module 500, the air outlet pipe 540 is hollow to form the second airflow cavity 541, the top end opening of the air outlet pipe 540 forms the third air outlet 5411, in the first state, the air outlet pipe 540 extends upward into the first airflow cavity 450, the mixture of garbage and air flow can be sucked from the third air inlet 511, flows through the air outlet pipe 540, flows out from the third air outlet 5411, flows into the extension pipe 220, and flows into the accommodating cavity 213 communicated with the extension pipe 220.

In the related art, since the air flow needs to flow through the second cleaning module 500 and the suction cleaning module 400 in sequence before flowing into the accommodating cavity 213 of the dust cup module 200, two sealing structures between the second cleaning module 500 and the suction cleaning module 400 and between the suction cleaning module 400 and the dust cup module 200 are encountered during the air flow process, and the sealing structures generally cause the fluid flow path to be uneven, and have a certain concave-convex shape, which is equivalent to two uneven points encountered during the fluid flow process. In the first state, the air outlet pipe 540 extends into the extension pipe 220, so that only the third air outlet 5411 of the air outlet pipe 540 and the first air inlet 221 of the dust cup module 200 are required to be sealed in a normal way, and the sealing structure between the suction cleaning module 400 and the dust cup module 200 is not affected.

As described above, the top end surface of the air outlet pipe 540 is inclined, and correspondingly, the bottom end surface of the limiting boss 222 is also inclined matching the shape of the top end surface, so that the top end surface and the bottom end surface can be completely attached. Through the laminating of two inclined planes, can also carry out spacing along self circumference to air-out pipeline 540, only when its circumference position aligns, just can install in place, and after installing in place, the rotation along circumference will be restricted.

When the air outlet pipe 540 is not inserted into the extension pipe 220, only the inner wall of the fixed end 710 is tightly attached to the outer wall of the air outlet pipe 540, and a gap is formed between the inner wall of the free end 720 and the outer wall of the air outlet pipe 540. During the process of inserting the air outlet pipe 540 into the extension pipe 220, the free end 720 is extruded by the outer wall of the air outlet pipe 540 and the inner wall of the extension pipe 220, and is sucked by the motor 300, the free end 720 is contracted towards the fixed end 710, meanwhile, the area between the free end 720 and the fixed end 710 is arched outwards, the outer circumferential surface of the arched part is abutted against the inner wall of the extension pipe 220, and the free end 720 is abutted against the outer wall of the air outlet pipe 540, so that sealing is completed. In this embodiment, when the air outlet pipe 540 is inserted into the extension pipe 220, the fixed end 710 is only needed to be plugged into the extension pipe 220, and then the air outlet pipe 540 is pushed into the extension pipe 220, so that the free end 720 can enter the extension pipe 220, thereby facilitating installation.

Preferably, in some embodiments, an annular groove is provided on the outer circumferential surface of the air outlet duct 540, the annular seal 700 is disposed in the annular groove, and the inner wall of the fixed end 710 is abutted against the groove wall of the annular groove.

Referring to fig. 3 to 5, in some embodiments, the dust cup module 200 includes a dust cup body 210, a side pipe 230, and a transition pipe 240, the dust cup body 210 having a receiving chamber 213, an extension pipe 220 extending outwardly from an end of the dust cup body 210 facing away from the main body 100, the side pipe 230 being located at one side of the dust cup body 210 in the second direction, the transition pipe 240 extending obliquely from the extension pipe 220 to the side pipe 230, the extension pipe 220, the transition pipe 240, the side pipe 230, and the receiving chamber 213 communicating in sequence.

Specifically, the dust cup main body 210 includes an upper cup portion 211 and a lower cup portion 212 which are sequentially arranged in a first direction and communicate with each other in their inner cavities to form a receiving cavity 213 for storing garbage. The main body 100 is connected to the upper cup 211, and the suction cleaning module 400 is fixedly installed to the lower cup 212. In the view of the drawing, the extension pipe 220 extends downward from the lower cup portion 212, and in the use state, the side pipe 230 is located at a side of the dust cup main body 210 near the cleaning area.

The side tube 230 is notched at one side near the upper cup portion 211 to communicate with the receiving chamber 213. And a silica gel blocking piece is installed at the notch position, and when the motor 300 is not started, the silica gel blocking piece covers the notch position to separate the accommodating cavity 213 from the inner cavity of the side pipe 230. When the motor 300 is turned on, the silica gel baffle is turned up under the action of suction force, so that the gap is not blocked, and the mixture of garbage and air flows into the extension pipe 220, then flows through the transition pipe 240 and the side pipe 230 in sequence, and flows into the accommodating cavity 213 from the gap.

Referring to fig. 3 and 9, the flow direction of the fluid in the first state in the cleaning apparatus according to the embodiment of the present application will be described, and the arrow direction shown in fig. 3 is the fluid flow direction. When the motor 300 is turned on to provide suction force, the garbage and air flow mixture is sucked from the third air inlet 511 of the second cleaning module 500, flows through the air outlet pipe 540, then enters the extension pipe 220, flows through the transition pipe 240 and the side pipe 230 in sequence, and flows into the accommodating chamber 213. The accommodating chamber 213 is provided therein with a filter 250, and the garbage and the air-flow mixture are filtered and separated by the filter 250, so that the garbage falls downward by gravity to be accumulated in the accommodating chamber 213, and the air-flow flows through the filter 250, upward from the inside of the filter 250, and enters the inner cavity of the body 100. The inside of the body 100 is installed with the sea paper 110, and the air flow entering the inside of the body 100 flows from the outside toward the inside of the sea paper 110, thereby completing the filtration. After filtration, dust particles and the like fall back into the accommodating chamber 213 by gravity, and the clean air flow continues upward from the inside of the HEPA 110 and enters the air inlet of the motor 300. The body 100 is further provided with an air outlet, and the air flowing out from the air outlet of the motor 300 is folded back, flows downward and around, and is finally discharged to the external environment from the air outlet. Because the air flow is filtered twice by the filter 250 and the HEPA 110 before flowing into the motor 300, dust particles in the air flow discharged to the external environment can be reduced, and the cleanliness of the air flow can be ensured as much as possible.

In the second state, the garbage and air flow path is similar to the above process, except that the garbage and air flow mixture is sucked from the second air inlet 451 of the suction cleaning module 400 and flows into the extension pipe 220.
