The following describes in detail the embodiments of the cleaning device according to the embodiments of the present application with reference to fig. 1 to 4.

Referring to fig. 1 to 3, a cleaning apparatus according to an embodiment of the present application includes an apparatus main unit including a housing 100 and a blower assembly 200, wherein the blower assembly 200 is disposed in the housing 100. The fan assembly 200 includes a motor 210 and a motor cover 220, the motor cover 220 is disposed around the outer circumference of the motor 210, a first air duct 300 is defined between the motor cover 220 and the motor 210, a second air duct 400 is defined between the motor cover 220 and the housing 100, and the first air duct 300 and the second air duct 400 are communicated with each other. The housing 100 has a first air outlet 110 connected to the first air duct 300 and a second air outlet 120 connected to the second air duct 400, wherein the first air outlet 110 faces the axial direction of the motor 210, and the second air outlet 120 faces the radial direction of the motor 210.

The motor cover 220 is used to be sleeved outside the motor 210 such that the outer circumferential wall of the motor 210 and the inner circumferential wall of the motor cover 220 are disposed to form a first air duct 300, and a second air duct 400 is formed between the outer circumferential wall of the motor cover 220 and the inner circumferential wall of the housing 100 such that the gas discharged from the motor 210 first enters the first air duct 300 and a part of the gas may enter the second air duct 400 from the first air duct 300.

In order to make the exhaust of the equipment host smoother, the casing 100 is provided with two air outlets, namely a first air outlet 110 and a second air outlet 120, and the air flow directions of the two air outlets are different, the first air outlet 110 faces the axial direction of the motor 210, and the second air outlet 120 faces the radial direction of the motor 210. Thus, when the air is discharged from the motor 210, the air is first discharged into the first air duct 300, a part of the air flows along the axial direction of the motor 210 and is discharged through the first air outlet 110, another part of the air continues to flow and is discharged into the second air duct 400, and the air in the second air duct 400 flows along the circumferential direction of the motor 210 and is then discharged from the second air outlet 120.

In the above arrangement, the air has two flowing air channels and air outlets, so that it is possible to prevent one of the first air channel 300 and the second air channel 400 from being exhausted smoothly, or one of the first air outlet 110 and the second air outlet 120 from being exhausted smoothly, and thus to prevent air noise caused by air turbulence in the housing 100.

That is, when the first air duct 300 and the first air outlet 110 are not smooth, the air can be exhausted from the equipment host through the second air duct 400 and the second air outlet 120, when the second air duct 400 and the second air outlet 120 are not smooth, the air can be exhausted from the equipment host through the first air duct 300 and the first air outlet 110, and the exhaust directions of the first air outlet 110 and the second air outlet 120 are different, so that the mutual interference during the exhaust can be avoided.

The cleaning device provided by the embodiment of the application comprises a device host, wherein the device host comprises a shell 100, a fan assembly, a first air duct 300 and a second air duct 400, the fan assembly comprises a motor 210 and a motor cover 220, and the shell 100 comprises a first air outlet 110 and a second air outlet 120. The fan assembly is arranged by arranging the shell 100, the second air channel 400 is defined by the fan assembly and the motor cover 220, the motor cover 220 is arranged to enclose the outer side of the motor 210, the first air channel 300 is defined by the motor cover 220, the first air outlet 110 is arranged outside the air outlet shell 100 for the first air channel 300, the second air outlet 120 is arranged outside the air outlet shell 100 for the second air channel 400, and therefore air to be discharged can be discharged outside the shell 100 through the first air channel 300 and the first air outlet 110, and the air can be discharged outside the shell 100 through the second air channel 400 and the second air outlet 120, so that air discharge is smooth, and air flow noise is low when the cleaning equipment is used.

In one possible implementation, the first exhaust port 110 is located at an end wall of the housing 100, and the second exhaust port 120 is located at a circumferential side wall of the housing 100. Wherein the end wall of the housing 100 is located outside the axial end of the motor 210, and the circumferential side wall of the housing 100 is located outside the motor 210.

In this way, the first exhaust port 110 may face the axial direction of the motor 210, the second exhaust port 120 may face the circumferential direction of the motor 210, and the exhaust directions of the first exhaust port 110 and the second exhaust port 120 may be different, so that the two exhaust directions are not interfered with each other.

Referring to fig. 3 and 4, in some embodiments, the housing 100 has an air inlet 130, axial ends of the air inlet 130 and the motor 210 are disposed opposite to each other, and the air inlet 130 and the first air outlet 110 are located on the same side end wall of the housing 100.

In this way, the air inlet 130 and the first air outlet 110 along the axial direction of the motor 210 and the second air outlet 120 along the circumferential direction of the motor 210 can be formed on the housing 100, and the air can enter the housing 100 through the air inlet 130 at the end wall of the housing 100 and further enter the motor 210, and the air exhausted from the motor 210 can also be exhausted out of the housing 100 through the first air outlet 110 at the end wall of the housing 100.

In one possible implementation, the first air outlet 110 is disposed around the air inlet 130, and the air flow direction of the air inlet 130 is opposite to the air flow direction of the first air outlet 110.

That is, the gas enters the housing 100 through the gas inlet in the axial direction of the motor 210, and the gas is discharged outside the housing 100 through the first gas outlet in the axial direction of the motor 210, so that the same side end wall of the housing 100 can be used for both gas inlet and gas outlet, and the direction of gas inlet is opposite to the direction of gas outlet, and the gas inlet and the gas outlet can be performed independently.

Referring to fig. 4, in order to avoid backflow of air entering and exhausting from the main machine of the apparatus, in one possible implementation manner, in the cleaning apparatus provided by the present application, an end wall of the housing 100 has a first partition 140, the first partition 140 is disposed around the circumference of the housing 100 and is blocked between the air inlet 130 and the first air outlet 110, the first partition 140 defines an air inlet channel 160, and the air inlet channel 160 is communicated with the air inlet 130.

Therefore, the first partition 140 can isolate the air inlet 130 and the first air outlet 110, and the air enters the air inlet channel 160 defined by the first partition 140 and enters the motor 210 along the air inlet 130, and the air exhausted from the motor 210 can flow along the first air channel 300 and then is exhausted out of the housing 100 through the first air outlet 110 outside the first partition 140, so that the air inlet and the air outlet are not interfered with each other, and the air inlet and the air outlet can be prevented from forming backflow, thereby avoiding causing airflow noise.

Referring to fig. 4, in some embodiments, the end wall of the case 100 further has a second partition 150, the second partition 150 is disposed one circumference along the circumferential direction of the case 100, and the second partition 150 is disposed around the outer circumferential side of the first exhaust outlet 110. The first and second partitions 140 and 150 define therebetween an exhaust passage 170, and the exhaust passage 170 communicates with the first exhaust port 110.

In this way, the exhaust passage 170 may be defined between the first and second partitions 140 and 150, the gas exhausted from the first exhaust outlet 110 enters the exhaust passage 170, the exhaust passage 170 may prevent the gas exhausted from the first exhaust outlet 110 from being mixed at the end of the housing 100, and the first and second partitions 140 and 150 may jointly define a reasonable passage for the equipment main unit to intake and exhaust, thereby allowing the gas to flow according to a preset path.

Referring to fig. 2 and 3, in one possible implementation manner, the peripheral wall of the motor cover 220 has air outlets 221 penetrating through opposite sides of the peripheral wall, the air outlets 221 include a first air outlet 2211 and a second air outlet 2212, the first air outlet 2211 and the second air outlet 2212 face the circumferential direction of the motor 210, and the first air outlet 2211 and the second air outlet 2212 are respectively disposed on opposite sides of the circumferential direction of the motor 210.

Thus, the first air duct 300 and the second air duct 400 may be mutually communicated through the air outlet 221, after the air is exhausted from the motor 210, the air enters the first air duct 300, a part of the air flows along the axial direction of the motor 210 and is exhausted through the first air outlet 110, and another part of the air flows along the circumferential direction of the motor 210 and enters the second air duct 400 through the first air outlet 2211 and the second air outlet 2212 on the peripheral wall of the motor cover 220 to be converged into a gas, and after the gas continues to flow to the second air outlet 120 along the second air duct 400, the gas is exhausted from the second air outlet 120 to the outside of the equipment host.

Referring to fig. 2 and 3, in some embodiments, the air outlet 221 further includes a third air outlet 2213, the second air outlet 2212 faces the radial direction of the motor 210, and the third air outlet 2213 is located between the first air outlet 2211 and the second air outlet 2212.

In this way, the gas exhausted through the third air outlet 2213 and the gas exhausted through the first air outlet 2211 and the second air outlet 2212 can be combined together to form a gas, and finally the gas is exhausted through the second air outlet 120.

In order to make the air outlet directions of the first air outlet 2211 and the second air outlet 2212 face the circumferential direction of the motor 210, in some embodiments, the first air outlet 2211 and the second air outlet 2212 are both disposed in a radial direction of the motor 210 in an inclined manner, and the air flow directions of the first air outlet 2211 and the second air outlet 2212 are opposite.

In this way, since the first air outlet 2211 and the second air outlet 2212 are both arranged in a radial inclined manner of the motor 210, the wall surface of the first air outlet 2211 and the wall surface of the second air outlet 2212 have a flow guiding effect, and can guide the air in the first air duct 300 to enter the second air duct 400 along the circumferential direction of the motor 210, further flow in the second air duct 400 in a clockwise direction or a counterclockwise direction at the same time, and collect into the same air to be discharged through the second air outlet 120.

Referring to fig. 1, in order to make the air intake and exhaust of the main machine of the apparatus smoother, in one possible implementation, the main machine of the apparatus further includes a sealing damper 500, the sealing damper 500 is abutted between the motor 210 and the housing 100, and/or the sealing damper 500 is abutted between the motor 210 and the motor cover 220, and the sealing damper 500 is disposed at least one end of the motor 210.

That is, the sealing damper 500 is disposed between at least one of the housing 100 and the motor cover 220 and the motor 210 such that the sealing damper 500 can seal a gap between the motor 210 and the housing 100 and/or the sealing damper 500 can seal a gap between the motor 210 and the motor cover 220, such that the air inlet and the air outlet of the motor 210 are isolated from each other, the air is not blown in, and the exhaust of the equipment main body is further smooth, thereby reducing the air flow noise of the equipment main body, and the sealing damper 500 can also reduce the noise generated by the vibration of the motor 210.

Referring to fig. 1, in some embodiments, the sealing damper 500 includes a first sealing damper 510 that surrounds an outer peripheral wall of an end of the motor 210 facing away from the air inlet 130, and that abuts between the motor 210 and the motor cover 220.

In this way, the first sealing vibration damper 510 may seal the gap between the motor 210 and the motor cover 220 at the end facing away from the air inlet 130, so that the gas does not flow through the gap between the motor 210 and the motor cover 220, and thus the gas may flow along a predetermined path, thereby avoiding the noise of the air flow caused by the air channeling.

Referring to fig. 1, in one possible implementation, the sealed vibration damper 500 may further include a second sealed vibration damper 520, where the second sealed vibration damper 520 is disposed at an end of the motor 210 facing the air inlet 130, and the second sealed vibration damper 520 includes a first sealed portion 521 and a second sealed portion 522 connected to each other, where the first sealed portion 521 abuts between a peripheral wall of the motor 210 and the motor cover 220, and the second sealed portion 522 abuts between an end wall of the motor 210 and the housing 100.

That is, the second sealing damper 520 half-wraps the end of the motor 210 facing the air inlet 130, the first sealing part 521 may seal the gap between the end of the motor 210 facing the air inlet 130 and the motor cover 220 to prevent the gas from flowing through the gap between the motor 210 and the motor cover 220, and the second sealing part 522 may seal the gap between the end of the motor 210 facing the air inlet 130 and the housing 100 to prevent the gas from flowing through the gap between the motor 210 and the housing 100, so that the gas may flow along a predetermined path to prevent the gas from being mixed.

Since the first sealing damper 510 is installed first and then the second sealing damper 520 is installed at the time of assembly, in order to secure sealing performance and damping effect, in one possible implementation, the wall thickness of the second sealing damper 520 is greater than that of the first sealing damper 510.

In this way, after the second sealing damper 520 is installed, the end wall of the housing 100 is installed to the circumferential side wall of the housing 100 such that the second sealing portion 522 of the second sealing damper 520 abuts between the end wall of the motor 210 and the housing 100, and the provision of the second sealing damper 520 having a thicker wall thickness can allow for a tight fit between the first sealing damper 510 and the motor 210 and a tight fit between the second sealing damper 520 and the motor 210, thereby effectively sealing and damping vibrations.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
