Description

Technical Field

[0001] This utility model belongs to the field of dehumidifier technology, specifically relating to a cleaning device. Background Technology

[0002] A cleaning device is a portable instrument commonly used to suck up accumulated liquid from surfaces such as glass, floor tiles, and tabletops for localized drying. Its basic working principle involves a drive unit that activates a negative pressure fan to draw in outside air along with the liquid through the suction port. After gas-liquid separation, the liquid is collected in a reservoir, while the gas is expelled. In existing handheld cleaning devices, the sucked-in liquid is separated from the gas in the reservoir. However, because the device inevitably shakes or tilts during use, the liquid temporarily stored in the reservoir can easily flow through the connected gas channel to the drive unit, potentially causing device malfunction or shortening its lifespan. Utility Model Content

[0003] This invention provides a cleaning device that addresses the problem that in existing cleaning devices, when the liquid temporarily stored in the reservoir is shaken, it can easily flow through the connected gas channel to the drive device, potentially causing equipment failure or shortening its lifespan.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A cleaning device, comprising:

[0006] The body has a handle, an air intake, and a first channel communicating with the air intake. The body also has a negative pressure fan blade mounting cavity and a drive device mounting cavity arranged in parallel. A partition is provided between the negative pressure fan blade mounting cavity and the drive device mounting cavity. The outer side of the body has an exhaust port communicating with the negative pressure fan blade mounting cavity.

[0007] A liquid reservoir is mounted on the machine body. The liquid reservoir has a storage chamber and a second channel. The air inlet of the second channel communicates with the first channel, and the air outlet of the second channel communicates with the storage chamber. The liquid reservoir also has a third channel. The air inlet of the third channel communicates with the storage chamber, and the air outlet of the third channel communicates with the negative pressure fan blade mounting cavity.

[0008] The suction assembly includes a negative pressure fan blade disposed in the negative pressure fan blade mounting cavity and a drive device disposed in the drive device mounting cavity. The negative pressure fan blade is used to draw in liquid from the air intake port and enter the liquid storage cavity through the first channel and the second channel. The output shaft of the drive device passes through the dividing part and is connected to the negative pressure fan blade.

[0009] A further embodiment: the negative pressure fan blade mounting cavity and the drive device mounting cavity are arranged side by side in the body, and the negative pressure fan blade mounting cavity is located in front of the drive device mounting cavity.

[0010] A further embodiment: The body is also provided with a fourth channel, the air inlet of the fourth channel is connected to the air outlet of the third channel, and the air outlet of the fourth channel is connected to the negative pressure fan blade mounting cavity.

[0011] A further solution: The fourth channel includes an L-shaped channel that extends downwards and bends backwards at the lower end toward the negative pressure fan blade mounting cavity.

[0012] A further embodiment: The air outlet of the fourth channel is provided with a cover whose diameter gradually increases from front to back, and the rear end of the cover is provided with an annular baffle extending from front to back. The negative pressure fan is located between the cover and the dividing part, and at least a portion of the front end of the negative pressure fan is surrounded by the annular baffle.

[0013] The negative pressure fan blade includes a negative pressure fan blade body located at the rear and several air guide plates arranged around the front side of the negative pressure fan blade body. The air guide plates are used to throw the airflow entering the negative pressure fan blade out circumferentially from the negative pressure fan blade.

[0014] Based on the above technical solution: by setting an annular baffle on the cover and having at least a portion of the front end of the negative pressure fan blade located within the space surrounded by the annular baffle, the annular baffle can prevent the sucked-in liquid from splashing everywhere. Combined with the circumferential air-throwing design of the air guide plate and the exhaust ports on both sides, the airflow and any remaining trace droplets can be discharged circumferentially to both sides, avoiding affecting the drive device.

[0015] A further embodiment: The exhaust port includes several exhaust holes disposed on the left and right sides of the negative pressure fan blade mounting cavity.

[0016] Based on the above technical solution: The above design makes it easier for the negative pressure fan blades to smoothly throw the liquid that has entered the negative pressure fan blade mounting cavity out of the circumference of the negative pressure fan blade outlet when the machine body is accidentally shaken. This avoids splashing.

[0017] A further embodiment: Each of the exhaust vents is arranged in an L-shape from the side wall to the bottom wall of the body.

[0018] Based on the above technical solution: the design of the exhaust port helps the water vapor sucked into the negative pressure fan blade mounting cavity to be discharged quickly, avoiding accumulation in the negative pressure fan blade mounting cavity.

[0019] A further embodiment: the air extraction port is located on the front side of the upper end of the machine body;

[0020] The liquid reservoir is located at the front of the machine body, and the handle is located at the rear of the machine body; the negative pressure fan mounting cavity and the drive device mounting cavity are both located at the lower part of the machine body.

[0021] Based on the above technical solution, the above structural layout is more reasonable and compact.

[0022] A further embodiment: the outlet end of the second channel and the inlet end of the third channel face opposite directions, and the third channel extends upward from the bottom wall of the liquid reservoir.

[0023] A further embodiment: the outlet end of the second channel is gradually inclined downward from back to front, the third channel extends upward from the bottom wall of the liquid reservoir, the inlet end of the third channel is located at the upper end of the third channel and faces the rear, and the outlet end of the third channel is located at the lower end of the third channel.

[0024] The beneficial effects of this utility model are as follows:

[0025] This invention physically isolates the drive unit mounting cavity from the negative pressure fan mounting cavity through the dividing part, and connects the liquid storage cavity to the negative pressure fan mounting cavity through the third channel. This structure ensures that when a user accidentally shakes the machine, causing liquid in the liquid storage cavity to splash into the third channel and the negative pressure fan mounting cavity, the liquid will be quickly flung out of the exhaust port by the negative pressure fan. The drive unit mounting cavity, which is tightly blocked by the dividing part, is effectively protected, thereby significantly reducing the risk of liquid intrusion into the drive unit area and improving the reliability and service life of the equipment.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1 to 6 As shown, this embodiment provides a cleaning device, including:

[0037] The body 1 is provided with a handle 3, an air intake 11 and a first channel 12 communicating with the air intake 11. The body 1 is also provided with a negative pressure fan blade mounting cavity 17 and a drive device mounting cavity 18 arranged in parallel. A dividing part 4 is provided between the negative pressure fan blade mounting cavity 17 and the drive device mounting cavity 18. An exhaust port 19 communicating with the negative pressure fan blade mounting cavity 17 is provided on the outside of the body 1.

[0038] A liquid reservoir 2 is mounted on the body 1. The liquid reservoir 2 has a liquid storage chamber 21 and a second channel 13. The air inlet of the second channel 13 is connected to the first channel 12, and the air outlet of the second channel 13 is connected to the liquid storage chamber 21. The liquid reservoir 2 also has a third channel 14. The air inlet of the third channel 14 is connected to the liquid storage chamber 21, and the air outlet of the third channel 14 is connected to the negative pressure fan blade mounting cavity 17.

[0039] The suction assembly includes a negative pressure fan 5 disposed in the negative pressure fan mounting cavity 17 and a drive device 6 disposed in the drive device mounting cavity 18. The output shaft of the drive device 6 passes through the dividing part 4 and is connected to the negative pressure fan 5. The negative pressure fan 5 is used to draw in liquid from the suction port 11 and allow the liquid to enter the liquid storage cavity 21 through the first channel 12 and the second channel 13, while the gas enters the negative pressure fan mounting cavity 17 through the third channel 14 and is discharged from the exhaust port 19 under the action of the negative pressure fan 5.

[0040] In a preferred embodiment, the negative pressure fan blade mounting cavity 17 and the drive device mounting cavity 18 are arranged side-by-side within the body 1, with the negative pressure fan blade mounting cavity 17 located in front of the drive device mounting cavity 18. The dividing section 4 is specifically a partition, through which the output shaft of the drive device 6 passes and connects to the negative pressure fan blade 5.

[0041] In some specific implementations, such as Figure 3 As shown, the body 1 is provided with a fourth channel 15. The air inlet of the fourth channel 15 is used to connect to the air outlet of the third channel 14, and the air outlet of the fourth channel 15 leads to the negative pressure fan blade mounting cavity 17.

[0042] In one specific structure, the fourth channel 15 is designed as an L-shaped channel. This channel first extends downward from the connection with the third channel 14, then bends horizontally backward, and finally the air outlet of the fourth channel 15 faces backward toward the negative pressure fan blade mounting cavity 17.

[0043] In some specific implementations, such as Figure 3 , Figure 5 and Figure 6 As shown, the air outlet of the fourth channel 15 is provided with a cover 16 whose diameter gradually increases from front to back. The cover 16 forms a space that gradually expands from front to back. The cover 16 is located in the negative pressure fan blade mounting cavity 17. The rear end of the cover 16 is provided with an annular baffle 161 extending from front to back. The negative pressure fan blade 5 is located between the cover 16 and the dividing part 4, and at least a part of the front end of the negative pressure fan blade 5 is surrounded by the annular baffle 161. A snap-fit ​​part 162 is provided around the outer rear end of the annular baffle 161. The negative pressure fan blade mounting cavity 17 is provided with a slot on the upper and lower sides of the snap-fit ​​part 162. The upper and lower sides of the snap-fit ​​part 162 are snapped into the slots, thereby forming a stable connection relationship.

[0044] The negative pressure fan blade 5 includes a main body located at the rear and several guide vanes 52 arranged around the front of the main body. The guide vanes 52 are used to deflect the airflow entering the negative pressure fan blade 5 circumferentially. Specifically, at least a portion of the front end of the guide vane 52 is located within the space surrounded by the annular baffle 161. A shaft connection portion 53 is provided in the middle of the main body of the negative pressure fan blade 5, and the output shaft of the drive device 6 is connected to the shaft connection portion 53.

[0045] In the event of a misoperation such as shaking of the machine body 1, causing liquid to enter the negative pressure fan blade mounting cavity 17 through the third channel 14 and the fourth channel 15, the exhaust port 19 includes several exhaust holes located on the left and right sides of the negative pressure fan blade mounting cavity 17 to ensure rapid discharge of the liquid. Specifically, each exhaust hole is L-shaped, extending from the side wall to the bottom wall of the machine body 1. The exhaust hole on the left side of the negative pressure fan blade mounting cavity 17 gradually bends downward from the left side wall towards the bottom wall, and the exhaust hole on the right side of the negative pressure fan blade mounting cavity 17 gradually bends downward from the right side wall towards the bottom wall. The left and right exhaust holes are symmetrically arranged.

[0046] In some specific implementations, such as Figures 1 to 3 As shown, in order to make the structural design more reasonable and convenient for user operation, the air extraction port 11 is located on the front side of the upper end of the body 1, and can be set to be flat to facilitate the suction of liquids from the surface of objects such as glass and floor tiles.

[0047] The liquid reservoir 2 is located at the front of the body 1, and the handle 3 is located at the rear of the body 1; the negative pressure fan blade mounting cavity 17 and the drive device mounting cavity 18 are both located at the lower part of the body 1.

[0048] In some specific implementations, such as Figure 3 and Figure 4 As shown, the outlet of the second channel 13 faces opposite directions to the inlet of the third channel 14. Specifically, the outlet of the second channel 13 is gradually inclined downwards from back to front, thereby guiding the liquid into the storage chamber 21. The third channel 14 extends upwards from the bottom wall of the storage tank 2, and the inlet of the third channel 14 is located at its upper end and faces rearwards. The design of the outlet of the second channel 13 and the inlet of the third channel 14 facing opposite directions facilitates the smooth entry of liquid into the storage chamber 21 and separation from gas. The outlet of the third channel 14 is located at its lower end.

[0049] In some specific embodiments, a removable cover 22 is also provided on the front side wall of the liquid reservoir 2. Opening the cover 22 allows the liquid in the liquid reservoir 21 to be emptied, while closing it prevents liquid leakage.

[0050] Working principle explanation:

[0051] When the equipment is working, the drive unit 6 drives the negative pressure fan blade 5 to rotate, generating negative pressure at the air intake 11, which draws in external liquid. The liquid sequentially enters the liquid storage chamber 21 through the first channel 12 and the second channel 13 for storage. The gas enters the negative pressure fan blade mounting chamber 17 through the third channel 14 at the top of the liquid storage chamber 21, and is finally discharged through the exhaust port 19. During this process, the dividing part 4 completely isolates the drive unit mounting chamber 18 from the negative pressure fan blade mounting chamber 17. If the machine body 1 shakes and liquid enters the negative pressure fan blade mounting chamber 17, it is blocked before the dividing part 4 and cannot contact the drive unit 6 behind it, thus effectively protecting the drive unit 6 from liquid intrusion.

[0052] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
