The following is a detailed description of specific examples.

As shown in fig. 1 to 5, an embodiment of the present utility model provides a dust collector, which includes a housing assembly 100 and a fan 107, wherein a fan cavity 103 and a dust cup cavity 104 which are mutually communicated are formed in the housing assembly 100, the housing assembly 100 is provided with an air inlet 105 which communicates the dust cup cavity 104 with the outside and an air outlet 106 which communicates the fan cavity 103 with the outside, the dust collector further includes a filtering device 200 which is arranged at a position where the fan cavity 103 communicates with the dust cup cavity 104, a dust prevention device 300 which is arranged on the housing assembly 100 and is used for controlling the opening and closing of the air outlet 106, and a dust prevention layer 303 which is arranged on an air outlet channel of the air outlet 106.

As shown in fig. 3 to 5, in the present embodiment, the dust-proof device 300 includes a seal 301 provided on the surface of the air outlet 106, and a switch 302, the seal 301 being connected to the housing assembly 100 through the switch 302, the switch 302 being used to switch the position of the seal 301 to open or close the air outlet 106. Specifically, the change-over switch 302 is similar to a push switch of a ball pen, and by pushing the change-over switch 302 to change the position of the sealing member 301, the position of the sealing member 301 may be adjusted by using a slide rail or the like, which is not limited in the embodiment of the present utility model. The seal 301 has an open position and a closed position, when the seal 301 is in the open position, the seal 301 is away from the air outlet 106 to keep the air outlet 106 open, at which time outside air can exchange with the inside air of the fan chamber 103; when the seal 301 is in the closed position, the seal 301 is positioned adjacent to the air outlet 106 to maintain the air outlet 106 closed, at which time ambient air may not exchange with the interior air of the fan chamber 103. When the seal 301 is in the closed position, the seal 301 is integrated with the housing assembly 100 to form a perfect oval shape, making the cleaner more aesthetically pleasing.

On the other hand, when the sealing member 301 is located at the open position, the fan 107 may be divided into two cases according to whether the fan 107 is opened, and at this time, the air in the fan chamber 103 is blown away from the housing assembly 100 through the air outlet 106 by the fan 107, and because the air flows out of the fan chamber 103 to the outside in one direction, the dust-proof measure of the position of the air outlet 106 is not required to be considered. When the fan 107 is closed and the sealing member 301 is located at the open position, the air in the outside and the air in the fan cavity 103 flow bidirectionally through the air outlet 106, so that dust in the outside air can fly into the fan cavity 103 through the air outlet 106, which is easy to cause the air outlet 106 to block or damage the fan 107 in the fan cavity 103 for a long time, and the dust collector is not normal in operation.

In this embodiment, although the housing assembly 100 in this embodiment is assembled by splicing, and is easy to disassemble and maintain, the small space inside the fan cavity 103 is relatively large, so that if dirt such as dust or hair enters the inside of the fan cavity 103, cleaning is inconvenient, and dirt such as dust or hair is preferably blocked outside the fan cavity 103. In this embodiment, a dust-proof layer 303 is disposed at a position inside the fan cavity 103 near the air outlet 106, and a clamping position for fixedly connecting the dust-proof layer 303 is disposed on the inner wall of the fan cavity 103 and is disposed on an air outlet channel of the air outlet 106 toward the fan cavity 103. The dust-proof layer 303 is used for blocking dust or hair from outside from entering the fan cavity 103, and also blocking fine dust particles from the dust cup cavity 104 in the fan cavity 103 from escaping to the outside. Considering that the air outlet 106 also needs to be breathable, the dust-proof layer 303 is a low-density filter layer such as filter cotton, a mesh enclosure or filter paper, so as to ensure ventilation of air. On the other hand, when the dust collector needs to be maintained, only the shell assembly 100 needs to be disassembled, and then the dust-proof layer 303 is cleaned or replaced with a new one, so that the use experience of a user is greatly improved. In particular, the dust-proof layer 303 may be disposed at an opening of the air outlet 106 near the outside, but may affect the overall appearance of the cleaner, and functionally corresponds to the embodiment disposed in the fan chamber 103. On the other hand, when the filter device 200 is blocked or broken, fine particles such as dust from the dust cup chamber 104 may pass through the filter device 200 to reach the fan chamber 103 and leave the cleaner through the air outlet 106, and the dust-proof layer 303 may serve as a final guarantee to intercept and filter the fine particles such as dust from the dust cup chamber 104.

As shown in fig. 5, in the present embodiment, the filter device 200 includes a first filter layer 201 and a second filter layer 202, the first filter layer 201 being disposed on a side facing the fan chamber 103, and the second filter layer 202 being disposed on a side facing the dirt cup chamber 104. The air in the dust cup cavity 104 passes through the first filter layer 201 and the second filter layer 202 under the negative pressure generated by the operation of the fan 107 and is sucked into the fan cavity 103, and objects such as dust and hair in the air are blocked and remained in the dust cup cavity 104, so that the air purifying operation effect of the dust collector is realized.

In this embodiment, the mesh density of the first filter layer 201 is lower than that of the second filter layer 202. Specifically, the first filter layer 201 is a low-density filter layer such as filter cotton, a mesh enclosure or filter paper, and the second filter layer 202 is a high-density filter layer such as a filter core or a HEPA filter. The advantage of such a design is that the first filter layer 201 is better at filtering larger objects such as hair than the second filter layer 202, whereas the second filter layer 202 is better at filtering finer particles than the first filter layer 201, which in combination achieve a better filtering effect. On the other hand, the cleaning is convenient, when more hairs but fewer tiny particles exist in the working environment of the dust collector, the hairs on the first filter layer 201 are simply cleaned, and the second filter layer 202 is not required to be cleaned or replaced, so that the maintenance time cost and the economic cost are reduced, and the user experience is improved.

As shown in fig. 2 and 5, in the present embodiment, the dust collector further includes an air guiding device 400 disposed at the air inlet 105, and the air guiding device 400 is provided with an air inlet channel for communicating the dust cup cavity 104 with the outside. Specifically, the air guide 400 is an "L" -shaped bent pipe. One end of the air guide 400 extends into the dirt cup chamber 104, and the other end communicates with a suction pipe of the cleaner to suck outside air into the dirt cup chamber 104.

In this embodiment, the air guide 400 includes a rotatable flapper 401 disposed at one end of the dirt cup chamber 104. The movable baffle 401 has lighter weight and is rotationally connected with one end of the air guide device 400 extending into the dust cup cavity 104 through a rotating shaft, when the fan 107 does not work, the movable baffle 401 closes one end of the air guide device 400 extending into the dust cup cavity 104 under the action of gravity, when the fan 107 works, negative pressure is generated in the dust cup cavity 104, and the movable baffle 401 rotates under the action of the negative pressure, so that one end of the air guide device 400 extending into the dust cup cavity 104 is opened. The movable plate 401 is used for closing the air guide device 400 when the dust collector stops working, and preventing objects such as dust and hair in the dust cup cavity 104 from flowing out of the air guide device 400 to the outside.

As shown in fig. 1 to 5, in the present embodiment, the housing assembly 100 includes a blower 107 housing 101 and a dust cup housing 102, the dust cup housing 102 being detachably mounted on the blower 107 housing 101; fan chamber 103 is formed in fan 107 housing 101 filter 200 and dust guard 300 are mounted on fan 107 housing 101, and dust cup chamber 104 is formed in dust cup housing 102; the dirt cup housing 102 is also provided with a first opening in communication with the filter assembly 200 and a second opening in communication with the air inlet 105. Specifically, in this embodiment, the dust cup housing 102 is connected with the fan cavity 103 through a buckle, and when the cleaning and replacement of the filtering device 200 are required or the dust cup cavity 104 is full, the dust cup housing 102 is only required to be disassembled, which is convenient and fast.

In this embodiment, the housing assembly 100 further includes supporting feet 500, and the supporting feet 500 are used for supporting between the housing assembly 100 and the ground, so that a ground clearance is formed between the housing assembly 100 and the ground. The support leg 500 can protect the bottom of the cleaner from scratches or damage caused by friction between the bottom of the cleaner and the ground.

In this embodiment, the housing assembly 100 further includes a bottom winding device 501, and the bottom winding device 501 is disposed in the ground clearance space for winding and accommodating the cable of the dust collector, so as to improve the aesthetic appearance of the dust collector.

The following describes the working principle of the dust collector: as shown in fig. 5, the arrows in the figure are the flow direction of the air. When the cleaner is in operation, the sealing member 301 is first pressed, the sealing member 301 is switched to the open position by the switch 302, and the air outlet 106 is opened. Then, the fan 107 is started to operate to generate negative pressure, the movable plate 401 is sucked open, external air is sucked into the dust cup cavity 104 through the air guide device 400 and filtered by the filtering device 200, and then flows into the fan cavity 103, and clean air in the fan cavity 103 passes through the dust-proof layer 303 and the air outlet 106 to flow into the outside again. After the dust collector stops working, the fan 107 is closed, the movable plate 401 is closed, the sealing element 301 is pressed, the sealing element 301 is switched to the closed position through the switch 302, the air outlet 106 is closed, and the cable is wound and stored in the bottom winding device 501 to be hidden.

In summary, the dust collector of the present utility model can realize the fast switching of the open state and the closed state of the air outlet 106 through the dust-proof device 300, thereby solving the problem that the air outlet 106 is blocked by dust when the traditional dust collector is idle, and meanwhile, the air outlet 106 is covered when the dust-proof device 300 is closed, so that the appearance of the dust collector is more concise and beautiful. Has the advantages of simple structure, convenient operation and attractive appearance.

In addition, due to the structural design of the dust-proof layer 303 arranged on the air outlet 106, dust blown from the dust cup cavity 104 to the fan cavity 103 due to breakage or failure of the filtering device 200 can be intercepted by the dust-proof layer 303 in the fan cavity 103 instead of being blown from the air outlet 106 to the outside, and the use experience of a user is improved. Meanwhile, the dustproof layer 303 is clamped on the clamping position, so that the dust collector is convenient to disassemble and replace or clean the dustproof layer 303, and the service life and the maintenance efficiency of the dust collector are improved.
