[0049] Reference Figures 1 to 4According to the technical solution of the utility model, a cleaning brush that automatically discharges detergent includes: a shell 100, a brush head 110 is provided at the lower end, and a liquid inlet pipe 120 is provided in the shell 100; a liquid storage tank 200 is connected to the shell 100, and the liquid storage tank 200 is connected to one end of the liquid inlet pipe 120; a negative pressure pump 300 is arranged in the shell 100, and the other end of the liquid inlet pipe 120 is connected to the air inlet end of the negative pressure pump 300; a liquid outlet pipe 400 is arranged in the shell 100, and the two ends of the liquid outlet pipe 400 are respectively connected to the air outlet end of the negative pressure pump 300 and the brush head 110; a power supply 500 is arranged in the shell 100, and the power supply 500 is used to supply power to the negative pressure pump 300; a first switch 600 is arranged in the shell 100, and the first switch 600 is used to control the on and off of the power supply 500 to control the start or stop of the negative pressure pump 300.

[0050] It is understandable that the liquid storage tank 200 can be directly fixedly connected to the housing 100, or can be detachably connected to the housing 100 through connection forms such as threads and snaps.

[0051] The use of the above-mentioned cleaning brush that automatically discharges detergent has at least the following beneficial effects: when the cleaning brush is needed, the power supply 500 is connected through the first switch 600 to start the negative pressure pump 300. After the negative pressure pump 300 extracts detergent from the liquid storage tank 200 through the liquid inlet pipe 120, it outputs it to the brush head 110 end through the liquid storage tank 200, so that the detergent in the liquid storage tank 200 enters the brush head 110, so that scrubbing can begin. The whole process does not require the use of other tools to spray or spray the detergent. The first switch 600 is controlled to control the on and off of the power supply 500 to control the start and stop of the negative pressure pump 300, thereby controlling the spraying of the detergent. There is no need to use an additional tank 210 filled with detergent to spray the detergent, which improves the convenience of cleaning.

[0052] According to some embodiments of the present invention, a bubbler 130 is further included. The bubbler 130 is disposed in the housing 100. Both ends of the bubbler 130 are respectively connected to the liquid outlet pipe 400 and the brush head 110. The bubbler 130 is used to break up the detergent into foam. By adding the bubbler 130, the detergent is already in foam when entering the brush head 110, thereby increasing the contact area with the brush head 110, improving the washing area of ​​the detergent, and also reducing the loss of detergent in the process of foaming the detergent by the brush head 110.

[0053] According to some embodiments of the present invention, the bubbler 130 is connected to the liquid outlet pipe 400 via a connector 140 , and a sealing ring 150 is provided between the connector 140 and the bubbler 130 , so as to prevent the detergent from leaking when entering the bubbler 130 .

[0054] According to some embodiments of the utility model, a foaming mesh group 131 is provided in the foamer 130, and the foaming mesh group 131 is used to break up the detergent into foam. The input end and the output end of the foaming mesh group 131 are both provided with meshes, and the detergent is broken up by the meshes to form foam, so that there is no need to stir the detergent to achieve foaming.

[0055] According to some embodiments of the present invention, the center of the liquid outlet at the lower end of the liquid outlet tube 400 is coaxially arranged with the central axis of the brush head 110, so that when the detergent flows through the brush head from the liquid outlet, it can flow evenly in all directions of the brush head 110, so that the cleaning effect of the brush head 110 is better.

[0056] According to some embodiments of the utility model, the liquid storage tank 200 includes: a tank body 210, connected to the shell body 100; a liquid extraction tube 220, arranged in the tank body 210; a joint cover 230, arranged at the liquid outlet end of the liquid extraction tube 220 and connected to the liquid extraction tube 220; a liquid extraction interface 240, arranged in the joint cover 230 and connected to the liquid extraction tube 220, and the liquid extraction interface 240 is used to connect to the liquid inlet end of the liquid inlet tube 120.

[0057] According to some embodiments of the present invention, the tank body 210 is detachably connected to the shell 100, and an elastic sealing component is further provided in the joint cover 230. The elastic sealing component is used to seal the liquid extraction interface 240, or to detach from the liquid extraction interface 240 under the action of the liquid inlet pipe 120, so that the liquid extraction pipe 220 is connected to the liquid inlet pipe 120. The elastic sealing component includes: a steel ball 250, which is movably arranged in the joint cover 230; a spring 260, whose two ends respectively abut the joint cover 230 and the steel column, and the spring 260 is used to make the steel ball 250 abut against the liquid extraction interface 240. It can be understood that when the liquid storage tank 200 is not installed to the shell 100, under the action of the spring 260, the steel ball 250 abuts against the liquid extraction interface 240, thereby achieving sealing of the liquid storage tank 200 and preventing the detergent from leaking out of the liquid storage tank 200. After the liquid storage tank 200 is installed in the shell 100, the liquid inlet end of the liquid inlet pipe 120 pushes the steel ball 250 into the joint cover 230 and squeezes the spring 260, so that the liquid extraction interface 240 is opened, and the liquid inlet pipe 120 is connected with the joint cover 230, thereby achieving connection between the liquid inlet pipe 120 and the liquid extraction pipe 220. At this time, the negative pressure pump 300 is started to extract the detergent from the tank body 210. After the liquid storage tank 200 is removed, under the action of the spring 260, the steel ball 250 is pushed to the liquid extraction interface 240 again and blocks the liquid extraction interface 240 to achieve sealing operation.

[0058] According to some embodiments of the utility model, it also includes a connecting seat 160, the brush head 110 is arranged on the connecting seat 160, and the connecting seat 160 is hinged to the lower end of the shell 100, and also includes: a motor 170, which is arranged in the shell 100; a transmission mechanism 180, which is arranged in the shell 100 and connected to the output end of the motor 170, and the output end of the transmission mechanism 180 is connected to the connecting seat 160, and the motor 170 is used to drive the connecting seat 160 and the brush head 110 to rotate through the transmission mechanism 180.

[0059] According to some embodiments of the utility model, a second switch 190 is further included, which is arranged on the shell 100. The second switch 190 is used to control the start and stop of the connecting seat 160. The negative pressure pump 300 is controlled to extract the detergent through the first switch 600. The rotation of the connecting seat 160 and the brush head 110 is controlled by the second switch 190. The two are controlled independently of each other. It can be understood that in this embodiment, the power supply 500 can be in the form of a disposable dry battery, a rechargeable battery or a direct power supply.

[0060] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", "extended embodiment" etc. may be used to describe several embodiments of the utility model. The specific features, structures, materials or characteristics in the several embodiments may be combined in accordance with the principles and purposes of the utility model.

[0061] Although some embodiments of the utility model have been shown and described in this specification, the utility model should not be limited to the above-mentioned embodiments. As long as the technical effects of the utility model are achieved by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of the present disclosure and without departing from the principles and purpose of the present utility model should be included in the scope of protection of the present disclosure and should be deemed to belong to the scope of protection of the utility model.
