Description

Technical Field

[0001] The utility model relates to the field of electrical appliances, in particular to a cleaning device. Background Art

[0002] In existing cleaning devices, a connecting hole is usually provided on the side wall of the dirt bucket receiving chamber to communicate with the suction motor. When the suction motor is in operation, the gas in the dirt bucket receiving chamber is sucked away by the suction motor, creating a negative pressure in the dirt bucket receiving chamber, thereby forming a suction airflow that draws the wastewater into the dirt bucket.

[0003] When the cleaning device is in operation, wastewater overflowing or splashing from the waste bucket falls into the waste bucket chamber outside the waste bucket. However, the connecting hole in existing cleaning devices is located relatively close to the bottom of the waste bucket chamber. Therefore, wastewater that falls into the waste bucket chamber can easily be sucked into the suction motor through the connecting hole. This water entering the suction motor increases the load on the impeller, significantly increasing the motor's power and current, causing the motor to overheat and burn out. Utility Model Content

[0044] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, this embodiment does not limit the present invention, and any modifications to the mechanism, method, or function made by a person skilled in the art based on this embodiment are all within the scope of protection of the present invention.

[0045] Terms used herein to denote relative spatial positions, such as "upper," "lower," "left," "right," "front," and "back," are used for ease of explanation to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It should be understood that, depending on the placement of the product, these terms may be intended to encompass orientations other than those depicted in the drawings and should not be construed as limitations on the claims. Furthermore, the descriptor "horizontal" as used herein does not necessarily mean perpendicular to gravity, although a certain degree of tilt is permitted.

[0046] like Figure 1-6 As shown, the present invention provides a cleaning device 100 , which can be a wet or dry vacuum cleaner. The cleaning device includes a housing 10 , a suction motor 30 , and a dirt container 20 .

[0047] A first accommodating space 11 , a second accommodating space 12 , and an intermediate space 18 communicating with the first accommodating space 11 and the second accommodating space 12 are formed in the housing 10 .

[0048] The suction motor 30 is disposed in the second accommodating space 12 and is used to generate negative pressure so that a fluid channel can be formed in the housing 10 that at least partially passes through the first accommodating space 11, the intermediate space 18, and the second accommodating space 12 in sequence. Figure 6 As shown in path S1.

[0049] The dirt bucket 20 is located in the first accommodating space 11. Under the action of the negative pressure generated by the suction motor 30, the fluid carrying dirt outside the shell 10 can enter the first accommodating space 11, the middle space 18 and the second accommodating space 12 in sequence through the fluid channel. When the fluid carrying dirt enters the middle space 18 from the first accommodating space 11, it will pass through the dirt bucket 20. When passing through the dirt bucket 20, the dirt inlet 21 of the dirt bucket 20 can collect dirt.

[0050] Cleaning device 100 also includes a communication structure 40, which is disposed in intermediate space 18. Intermediate space 18 connects to first accommodating space 11 and second accommodating space 12 through communication structure 40. Communication structure 40 specifically includes a first communication port 42 and a second communication port 43, which communicate with each other. The first communication port 42 communicates with first accommodating space 11, and the second communication port 43 communicates with second accommodating space 12. When cleaning device 100 is placed on a surface to be cleaned, first communication port 42 is positioned above second communication port 43. After passing through waste container 20, fluid carrying dirt enters second accommodating space 12 through first communication port 42 and second communication port 43, respectively.

[0051] The aforementioned waste is typically sewage. After the fluid carrying the sewage passes through the sewage tank 20, most of the sewage remains within the sewage tank 20. However, some sewage may overflow or splash out of the sewage tank 20, flowing into an area outside the sewage tank 20 within the first accommodating space 11 and accumulating at the bottom of the first accommodating space 11. The aforementioned "area outside the sewage tank 20" specifically refers to the gap between the sidewalls of the first accommodating space 11 and the sewage tank 20. In the above arrangement, the first connecting port 42 is positioned above the second connecting port 43, allowing the first connecting port 42 to be as far away from the bottom of the first accommodating space 11 as possible. This prevents sewage accumulated in the gap from being drawn into the suction motor 30, reducing the load on the impeller within the suction motor 30 and preventing the suction motor 30 from burning out due to overheating. This ensures stable operation of the suction motor 30 and extends its service life.

[0052] As a preferred embodiment of this embodiment, when the cleaning device 100 is placed on the surface to be cleaned, the first communication port 42 is also located above the sewage inlet 21. In this way, when sewage in the sewage tank 20 overflows or splashes downward from the sewage inlet 21, it will not be sucked into the suction motor 30, further protecting the suction motor 30.

[0053] In this embodiment, the connecting structure 40 is formed as a box body 44, and an intermediate cavity 41 is formed inside the box body 44. The first connecting port 42 and the second connecting port 43 are connected to each other through the intermediate cavity 41. The first connecting port 42 and the second connecting port 43 are both opened on the box body 44. After passing through the sewage bucket 20, the fluid will enter the second accommodating space 12 through the first connecting port 42, the intermediate cavity 41, and the second connecting port 43 in sequence.

[0054] Furthermore, the cleaning device 100 includes a partition 15 disposed between the intermediate space 18 and the second accommodating space 12. A connecting hole 151 is defined in the partition 15. The box body 44 is removably connected to the partition 15. When the box body 44 is connected to the partition 15, the second connecting port 43 cooperates with the connecting hole 151 to connect the intermediate cavity 41 with the second accommodating space 12. In this manner, after passing through the waste container 20, the fluid enters the second accommodating space 12 through the first connecting port 42, the intermediate cavity 41, the second connecting port 43, and the connecting hole 151. When the box body 44 needs to be cleaned, the user can remove the box body 44 from the partition 15 and, after cleaning is complete, reattach the box body 44 to the partition 15.

[0055] Combine Figure 1 、 4 As shown in Figures 5 and 7, to enable the box body 44 to be detachably connected to the partition 15, two lugs 443 are formed on the box body 44, each located on opposite sides thereof. Each lug 443 has a connecting hole 444. The partition 15 has two screw holes 152 formed thereon, corresponding to the two connecting holes 444. The cleaning device 100 also includes a screw member 70 that connects the corresponding connecting holes 444 and the screw holes 152. When the box body 44 needs to be removed from the partition 15, the screw member 70 can be screwed out of the screw hole 152. When the box body 44 needs to be installed on the partition 15, the screw member 70 is inserted into the connecting hole 444 and screwed into the screw hole 152.

[0056] The box body 44 includes a first box body 441 and a second box body 442 that are detachably connected together. The intermediate cavity 41 is formed by the first box body 441 and the second box body 442. The first communication port 42 is provided on the first box body 441, and the second communication port 43 is provided on the second box body 442. After the first box body 441 and the second box body 442 are disassembled, it is easier to clean the interior of the box body 44. After cleaning is completed, the first box body 441 and the second box body 442 can be reassembled.

[0057] Specifically, a socket 445 is provided on the side of the second box body 442 facing the first box body 441, and at least a portion of the first box body 441 is inserted into the second box body 442 from the socket 445. When at least a portion of the first box body 441 is inserted into the second box body 442 from the socket 445, the first box body 441 and the second box body 442 are connected together. When the first box body 441 and the second box body 442 need to be separated, the first box body 441 can be pulled out of the second box body 442 from the socket 445.

[0058] Furthermore, one of the first and second boxes 441, 442 is provided with a buckle 4411, and the other is provided with a slot 4421 that cooperates with the buckle 4411. When the buckle 4411 is buckled into the slot 4421, at least a portion of the first box 441 is inserted into the second box 442 from the socket 445. The cooperation between the buckle 4411 and the slot 4421 allows the first and second boxes 441, 442 to be more reliably connected. When the first and second boxes 441, 442 need to be separated, the buckle 4411 needs to be disengaged from the slot 4421, and the first box 441 needs to be pulled out of the socket 445 and out of the second box 442.

[0059] In this embodiment, the buckle 4411 is provided on the first box body 441 , and the slot 4421 is provided on the second box body 442 . There are two buckles 4411 and two slots 4421 .

[0060] Continue to combine Figure 8-9 As shown, the housing 10 includes a wall 17 that encloses and forms the second accommodating space 12. The suction motor 30 includes an air intake 31 and an air outlet 32. When the suction motor 30 is in operation, air is drawn in through the air intake 31 and discharged out through the air outlet 32. An air inlet 171 is formed in the wall 17 near the air intake 31 and communicates with the communication hole 151. The cleaning device 100 also includes a sealing ring 60 that connects the partition 151 and the air inlet 171 and encloses a sealed channel 61. The communication hole 151 and the air inlet 171 are communicated through the sealed channel 61. With the above arrangement, when the suction motor 30 is operating, the fluid within the first accommodating space 11 flows into the second accommodating space 12 through the connecting hole 151, the sealed passage 61, and the air inlet 171 in sequence. After passing through the air inlet 171, the fluid is drawn into the suction motor 30 through the air inlet 31 of the suction motor 30 and then discharged from the suction motor 30 through the air outlet 32 ​​of the suction motor 30. The provision of the sealed passage 61 prevents leakage of the fluid as it flows from the connecting hole 151 to the air inlet 171. The suction motor 30 can effectively draw air from the first accommodating space 11, thereby ensuring that the cleaning device 100 effectively draws dirt.

[0061] In this embodiment, a sealed cavity 16 is formed between the box body 44 and the partition 15, and the second communicating port 43 and the communicating hole 151 are connected through the sealed cavity 16. When the fluid in the first accommodating space 11 flows into the second accommodating space 12, it will pass through the first communicating port 42, the intermediate cavity 41, the second communicating port 43, the sealed cavity 16, the communicating hole 151, the sealed channel 61, and the air inlet 171 in sequence. The setting of the sealed cavity 16 ensures that the fluid will not leak when it flows from the second communicating port 43 to the communicating hole 151.

[0062] In this embodiment, the sewage inlet 21 is open upward, and a sewage inlet channel 131 is formed on the housing 10. The sewage inlet channel 131 includes an inlet end 1311 located outside the housing 10, an outlet end 1312 located within the first accommodating space 11 and above the sewage inlet 21. The housing 10 includes a cover portion 1321 located above the outlet end 1312, and an annular portion 1322 extending downward from the cover portion 1321 into the interior of the sewage bucket 20. The annular portion 1322 is arranged around the outlet end 1312 and, together with the cover portion 1321, forms a guide channel 132. The fluid channel at least partially includes the sewage inlet channel 131 and the guide channel 132. When the cleaning device 100 is placed on the surface to be cleaned, the suction motor 30 is operated, and the fluid carrying dirt from the outside will flow into the sewage bucket 20 through the sewage inlet channel 131 and the guide channel 132, thereby facilitating the collection of dirt by the sewage bucket 20.

[0063] The cleaning device 100 also includes a seal 50 arranged between the wall 17 and the suction motor 30. The seal 50 and the suction motor 30 separate the second accommodating space 12 into a first chamber 121 and a second chamber 122. The air inlet 171 and the air intake 31 are connected through the first chamber 121, and the air outlet 32 ​​is connected to the second chamber 122.

[0064] In the above-mentioned setting, the second accommodating space 12 is divided into a first chamber 121 and a second chamber 122, and the air inlet 171 and the air intake 31 are connected through the first chamber 121, so that the suction motor 30 can inhale the gas in the first accommodating space 11 as much as possible, rather than the gas in the second accommodating space 12, thereby ensuring the effect of the cleaning device 100 in sucking out dirt.

[0065] The second chamber 122 is connected to the outside of the housing 10. The gas discharged from the air outlet 32 ​​of the suction motor 30 will first enter the second chamber 122 and then flow out of the second chamber 122 to the outside of the housing 10. It can be imagined that an air outlet connecting the second chamber 122 and the outside of the housing 10 is opened on the wall 17.

[0066] like Figure 6As shown, in this embodiment, the fluid channel at least partially passes through the first accommodating space 11, the intermediate space 18, and the second accommodating space 12 in sequence. More specifically, the fluid channel at least partially passes through the sewage inlet channel 131, the guide channel 132, the sewage bucket 20, the first connecting port 42, the intermediate cavity 41, the second connecting port 43, the sealed cavity 16, the connecting hole 151, the sealed channel 61, the air inlet 171, the first chamber 121, the air intake 31 of the suction motor 30, the air outlet 32 ​​of the suction motor 30, the second chamber 122, and finally passes through the wall 17 and the shell 10 to the outside of the shell 10. When the cleaning device 100 is placed on the surface to be cleaned, the suction motor 30 works, and the fluid carrying dirt outside the shell 10 will enter the interior of the dirt bucket 20 through the dirt inlet channel 131 and the guide channel 132. After the dirt in the fluid is collected by the dirt bucket 20, the fluid will pass through the first connecting port 42, the middle cavity 41, the second connecting port 43, the sealed cavity 16, the connecting hole 151, the sealed channel 61, the air inlet 171, and the first chamber 121 in sequence into the air intake 31 of the suction motor 30, and then be discharged from the air intake 31 of the suction motor 30 to the second chamber 122, and finally flow out from the second chamber 122 to the outside of the shell 10.

[0067] In this embodiment, the air intake 31 of the suction motor 30 is located at one axial end thereof, and a plurality of air outlets 32 are provided and circumferentially arranged around the suction motor 30. The cleaning device 100 also includes a silencer 80, which is provided between the multiple air outlets 32 and the wall 17 to avoid the noise generated by the gas discharged from the multiple air outlets 32 directly impacting the wall 17.

[0068] In order to dissipate heat from the suction motor 30 when it is working, a heat dissipation air inlet 172 and a heat dissipation air outlet 173 are provided on the wall 17 and the shell 10 near the wall 17. External air can enter the second accommodating space 12 through the heat dissipation air inlet 172, and after flowing through the suction motor 30, flow out from the heat dissipation air outlet 173 to the outside of the shell 10. When flowing through the suction motor 30, the external air can take away the heat from the suction motor 30.

[0069] To sum up, when the existing cleaning device is in use, sewage may accumulate in the area of ​​the first accommodating space outside the sewage barrel. In the utility model, the first connecting port 42 is arranged above the second connecting port 43, so that the first connecting port 42 can be as far away as possible from the sewage accumulated at the bottom of the first accommodating space 11. In this way, the sewage is not easily sucked into the suction motor 30, reducing the load of the impeller in the suction motor 30, avoiding the suction motor 30 from burning due to overheating, ensuring that the suction motor 30 can operate stably and extending the service life of the suction motor 30.
