[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Figure 1-4 As shown, the spraying surface cleaning device includes a housing 1, a driving member 2, a brush head 3, a flow guide assembly 4, and a flow guide member 5. The driving member 2 is disposed in the housing 1. The flow guide assembly 4 is disposed in the housing 1 and has a flow guide channel 401. The brush head 3 has a spray chamber 301 and bristles 302 arranged around the spray chamber 301. One end of the flow guide member 5 is connected to the output end of the driving member 2 and the other end is connected to the brush head 3. It has a flow guide channel 501 connecting the spray chamber 301 and the flow guide channel 401. The flow guide member 5 and the brush head 3 are driven by the driving member 2 to rotate synchronously relative to the flow guide assembly 4. The driving member 2 can be, but is not limited to, a motor. The present embodiment provides a spray-type surface cleaning device to solve the problem that the drainage pipe of the existing surface cleaning device is located on one side of the brush head. When the drainage pipe sprays water or foam to the brush head, the water or foam falls on a certain part of the brush head and is sprayed around due to the rotation of the brush head, and the water or foam is unevenly distributed on the brush head, resulting in poor cleaning effect. The method mainly adopts the following steps: configuring the brush head 3 to have a spray chamber 301 and bristles 302 arranged outside the spray chamber 301, configuring a guide component 4 with a guide channel 401 on the shell 1, and configuring a guide member 5 connecting the guide channel 401 and the spray chamber 301 between the brush head 3 and the driving member 2. When the brush head 3 rotates, water or foam can be sprayed from the guide channel 401 through the drainage channel 501 into the spray chamber 301, and evenly sprinkled on the bristles 302 under the action of centrifugal force, thereby achieving good cleaning ability.

[0024] In the embodiment of the present invention, the flow guide member 5 has a flow guide portion 502 located within the flow guide channel 401. The outer wall of the flow guide portion 502 is spaced apart from the inner wall of the flow guide channel 401 to form a flow passage 503. The flow guide portion 502 has a flow outlet 504 connecting the flow guide channel 401 and the flow guide channel 501. The above arrangement, by configuring the flow guide member 5 with the flow guide portion 502 spaced apart from the flow guide channel 401 and configuring the flow outlet 504 connecting the flow guide channel 401 and the flow guide portion 502, ensures that the flow guide channel 501 is continuously connected to the flow guide channel 401 when the flow guide member 5 rotates relative to the flow guide assembly 4, thereby achieving a good connection effect.

[0025] In the embodiment of the present invention, there are a plurality of drainage ports 504, which are spaced apart circumferentially around the drainage member 5. This arrangement facilitates the flow of water or foam from the guide channel 401 into the drainage channel 501, achieving a better connection effect.

[0026] In this embodiment of the present invention, the flow guide assembly 4 has two through-holes 402. The flow guide member 5 extends from one through-hole 402 into the flow guide channel 401 and from the other through-hole 402 out of the flow guide channel 401. A sealing ring (not shown) is provided on the flow guide member 5, which respectively abuts against the inner wall of the through-hole 402 and the outer wall of the flow guide member 5. This arrangement, by disposing the sealing ring on the flow guide member 5 and abutting against the inner wall of the through-hole 402 and the outer wall of the flow guide member 5, ensures a good seal between the assembly of the flow guide member 5 and the flow guide assembly 4, preventing water or foam from escaping.

[0027] In the embodiment of the present invention, the outer wall of the flow guide 5 is formed with a sealing groove 505 for the sealing ring to be placed in. The above arrangement provides the sealing ring with good assembly stability by configuring the sealing groove 505 for the sealing ring to be placed in the outer wall of the flow guide 5.

[0028] In the embodiment of the present invention, the flow guide assembly 4 includes a horizontal connecting rod 403, a vertical connecting rod 404 and a liquid inlet rod 405. The horizontal connecting rod 403 is provided on the flow guide member 5, and one end of the vertical connecting rod 404 is connected to the liquid inlet rod 405 and the other end is connected to the horizontal connecting rod 403. The vertical connecting rod 404 is provided with a fastener (not shown in the figure) for locking it to the housing 1. The flow guide channel 401 extends from the liquid inlet rod 405 to the horizontal connecting rod 403. The above arrangement makes the assembly of the flow guide assembly 4 with the housing 1 and the flow guide member 5 compact and reasonable by configuring the flow guide assembly 4 as a horizontal connecting rod 403 provided on the flow guide member 5 and a vertical connecting rod 404 connecting the liquid inlet rod 405 and the horizontal connecting rod 403.

[0029] In this embodiment of the present invention, the housing 1 has an inner chamber 101 and a partition 102. The partition 102 divides the inner chamber 101 into an upper chamber 103 and a lower chamber 104. The driver 2 is accommodated in the upper chamber 103, with its output end extending into the lower chamber 104. The flow guide 5 and the horizontal connecting rod 403 are accommodated in the lower chamber 104. The vertical connecting rod 404 extends from the lower chamber 104 into the upper chamber 103 and is connected to the liquid inlet rod 405. The above arrangement, by arranging the driver 2 in the upper chamber 103 and the flow guide 5 and the horizontal connecting rod 403 in the lower chamber 104, ensures that the components are reasonably and compactly distributed within the housing 1.

[0030] In this embodiment of the present invention, the flow guide member 5 extends through the horizontal connecting rod 403 from its middle portion. A reinforcement rod 7 is provided between the housing 1 and the horizontal connecting rod 403. The reinforcement rod 7 and the vertical connecting rod 404 are arranged axially opposite to each other. This arrangement, by placing the flow guide member 5 in the middle of the horizontal connecting rod 403, allows the flow channel 401 to be evenly distributed around the drainage portion 502, resulting in a better liquid discharge effect. Furthermore, by placing the reinforcement rod 7 between the housing 1 and the horizontal connecting rod 403, the assembly of the horizontal connecting rod 403 is stabilized.

[0031] In the embodiment of the present invention, the end of the guide member 5 extending into the spraying chamber 301 is located at the geometric center of the spraying chamber 301. Since the end of the guide member 5 extending into the spraying chamber 301 is located at the geometric center of the spraying chamber 301, the water or foam can be evenly distributed on the bristles 302 when the guide member 5 sprays.

[0032] In the embodiment of the present invention, the flow guide member 5 is respectively threadedly connected to the output end of the driving member 2 and the brush head 3. Since the flow guide member 5 is respectively threadedly connected to the output end of the driving member 2 and the brush head 3, the assembly and maintenance of the flow guide member 5, the brush head 3 and the driving member 2 are facilitated.
