Description

Technical Field

[0001] This invention belongs to the technical field of high-pressure cleaning machines, and in particular, it is a floor brush with pressure adjustment and liquid suction functions. Background Technology

[0002] Floor cleaning and maintenance is an important part of daily cleaning routines. Clean, shiny floors provide a pleasant living environment for the family and reduce bacterial growth, thus protecting family health. Specialized cleaning tools are needed for floor cleaning, and floor brushes are among the commonly used tools.

[0003] To improve the cleaning performance of floor brushes, a high-pressure washer is combined with the floor brush. Specifically, the spray gun of the high-pressure washer is attached to the floor brush, which is equipped with high-pressure nozzles. High-pressure water is sprayed out from the high-pressure nozzles to clean the floor. Since some floors or surfaces to be cleaned have oil stains or other stubborn stains, soap or cleaning solution needs to be sprayed onto the surface before scrubbing with the floor brush to remove the dirt. Existing floor brushes do not have an integrated cleaning solution, requiring manual application of soap during the cleaning process, making the cleaning operation very cumbersome. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a floor brush with pressure regulation and liquid absorption functions. The technical problem to be solved by this invention is: how to improve the convenience of using the floor brush during the cleaning process.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A floor brush with pressure regulation and liquid suction functions is characterized by comprising a housing, a rotating body, a pressure relief nozzle, a soap dispenser and a pressure regulating valve, all mounted on the housing. The pressure regulating valve includes a valve body with a main water channel and a high-pressure water jet channel connected to the main water channel. The rotating body is mounted on the valve body and has a high-pressure nozzle. The input water flow in the main water channel is sprayed downward through the high-pressure water jet channel, the rotating body, and the high-pressure nozzle. A soap liquid channel is formed between the soap dispenser and the pressure relief nozzle, and a pressure relief water jet channel is formed between the pressure regulating valve and the pressure relief nozzle. The outlet end of the soap liquid channel is connected to the pressure relief nozzle. When the input water flow in the main water channel flows through the pressure relief water jet channel and passes through the pressure relief nozzle, a Venturi tube vacuum effect is generated. The soap liquid in the soap dispenser is sucked into the pressure relief nozzle through the soap liquid channel and then sprayed downward.

[0007] When the floor brush is in normal use, the spray gun is turned on, and high-pressure water enters the main water channel. At this time, the high-pressure water is split into two streams. One stream of high-pressure water is sprayed downwards through the high-pressure water jet channel, the rotating body, and the high-pressure nozzle. The other stream of high-pressure water is sprayed downwards through the pressure relief water jet channel and the pressure relief nozzle. When the high-pressure water flows through the pressure relief nozzle, a Venturi tube vacuum effect is generated. The soap solution in the soap dispenser is drawn into the pressure relief nozzle through the soap solution channel and then sprayed downwards. After both water and soap solution are sprayed onto the floor, it is convenient for the floor brush to scrub the floor. This structure realizes automatic soap solution absorption, and the pressure regulating valve can adjust the water flow rate entering the pressure relief water jet channel, thereby controlling and regulating the pressure of the high-pressure water jet, improving the convenience of using the floor brush.

[0008] In the aforementioned floor brush with pressure regulation and liquid suction functions, a rotating shaft is installed inside the valve body. The rotating shaft contains the high-pressure water jet channel. The rotating body includes a vertically arranged rotating sleeve connected to the rotating shaft and capable of circumferential rotation relative to the shaft. Two horizontally arranged rotating pipes are symmetrically installed on the outer wall of the rotating sleeve, communicating with the rotating sleeve. Each rotating pipe has a high-pressure nozzle connected to its outer end. The nozzles of both high-pressure nozzles are angled downwards at opposite angles. High-pressure water from the main water channel sequentially enters the high-pressure water jet channel, the rotating sleeve, and the rotating pipes, finally exiting downwards from the high-pressure nozzles. Because the nozzles of both high-pressure nozzles are angled downwards at opposite angles, the reaction force of the jet propels the rotating body to rotate continuously around the center of the rotating shaft, achieving circumferential water spraying, significantly increasing the cleaning area and improving the cleaning effect on the floor.

[0009] In the aforementioned floor brush with pressure regulation and liquid suction functions, the pressure regulating valve includes a valve core housed within the valve body and a knob located at the top of the valve body that rotates the valve core. The valve core has a slotted hole on its side wall that communicates with the main water channel. Rotating the knob controls the communication area between the slotted hole and the main water channel. Initially, the slotted hole is not connected to the main water channel, preventing high-pressure water from entering the valve core. Rotating the knob rotates the valve core, adjusting the opening of the slotted hole and thus regulating the communication area between the slotted hole and the main water channel. This allows high-pressure water from the main water channel to sequentially enter the valve core and the pressure relief nozzle, thereby controlling the water pressure in the high-pressure water jet channel.

[0010] In the aforementioned floor brush with pressure regulation and liquid suction functions, the pressure relief nozzle has a vertically arranged spray hole and a horizontally arranged liquid suction hole, the valve core has the aforementioned pressure relief water jet channel, the pressure relief water jet channel is connected to the pressure relief nozzle, the lower end of the pressure relief channel is connected to the upper end of the spray hole, one end of the liquid suction hole is connected to the soap liquid channel, and the other end is connected to the spray hole.

[0011] In the aforementioned floor brush with pressure regulation and liquid absorption functions, the spray hole is a Venturi tube hole that is small in the middle and large at both ends, and the liquid outlet end of the soap liquid channel is connected to the upper end of the spray hole.

[0012] In the aforementioned floor brush with pressure regulation and liquid absorption functions, the floor brush also includes a liquid absorption tube, a pipe connector, and a one-way valve assembly. One end of the liquid absorption tube extends to the bottom of the soap dispenser, and the other end of the liquid absorption tube is inserted into one end of the pipe connector. The other end of the pipe connector is inserted into a pressure relief nozzle, and the one-way valve assembly is disposed inside the pipe connector. When water flows through the pressure relief nozzle, a venturi effect is created, drawing soap solution from the soap dispenser into the soap solution channel and opening the one-way valve assembly. The soap solution then enters the pressure relief nozzle and is sprayed out through the leak nozzle. When the spray gun is closed, the one-way valve assembly automatically resets, and the soap solution channel is re-sealed. During subsequent brushing of the floor or walls, even under the siphon effect, the soap solution cannot push open the one-way valve assembly, ensuring that the soap solution channel remains blocked, thus solving the problem of leakage when soap solution is not in use.

[0013] In the aforementioned floor brush with pressure regulation and liquid absorption functions, the one-way valve assembly includes a ball bearing and a spring. One end of the spring abuts against the ball bearing, causing the ball bearing to always tend to block the soap solution channel. When water flows through the pressure relief nozzle, creating a venturi effect, the soap solution pushes open the ball bearing, causing it to move to one side against the spring force, thus opening the soap solution channel. When the spray gun is closed, the ball bearing automatically resets under the spring's action, re-sealing the soap solution channel and preventing leakage due to the siphon effect.

[0014] Compared with the prior art, the floor brush with pressure regulation and liquid absorption functions of the present invention has the following advantages: When the floor brush is in normal use, the spray gun is turned on, and high-pressure water enters the main water channel. At this time, the high-pressure water is divided into two paths. One path of high-pressure water is sprayed downward through the high-pressure water jet channel, the rotating body, and the high-pressure nozzle. The other path of high-pressure water is sprayed downward through the pressure relief water jet channel and the pressure relief nozzle. When the high-pressure water flows through the pressure relief nozzle, a Venturi tube vacuum effect is generated. The soap solution in the soap dispenser is sucked into the pressure relief nozzle through the soap solution channel and then sprayed downward. After both water and soap solution are sprayed onto the ground, it is convenient for the floor brush to scrub the ground. This structure realizes automatic absorption of soap solution, and the pressure regulating valve can adjust the water flow rate entering the pressure relief water jet channel, thereby controlling and regulating the pressure of the high-pressure water jet, improving the convenience of using the floor brush.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 and Figure 2As shown, this floor brush with pressure regulation and liquid suction functions includes a housing 13, a rotating body 8, a pressure relief nozzle 2, a soap dispenser 1 and a pressure regulating valve, all mounted on the housing 13. The pressure regulating valve includes a valve body 9, which has a main water channel 90 and a high-pressure water jet channel 91 connected to the main water channel 90. The rotating body 8 is mounted on the valve body 9 and has a high-pressure nozzle 12. The input water flow in the main water channel 90 is sprayed downward through the high-pressure water jet channel 91, the rotating body 8 and the high-pressure nozzle 12. In this embodiment, a rotating shaft 14 is installed inside the valve body 9. The rotating shaft 14 has a high-pressure water jet channel 91. The rotating body 8 includes a rotating sleeve 80 arranged vertically. The rotating sleeve 80 is connected to the rotating shaft 14 and can rotate circumferentially relative to the rotating shaft 14. Two rotating pipes 81 arranged horizontally are symmetrically installed on the outer wall of the rotating sleeve 80. The rotating pipes 81 are connected to the rotating sleeve 80. The outer end of each rotating pipe 81 is connected to a high-pressure nozzle 12. The nozzles of the two high-pressure nozzles 12 are both arranged obliquely downward, and the orientations of the two nozzles are at opposite angles. When the floor brush is in normal use, the spray gun is turned on, and high-pressure water enters the main water channel 90. At this time, the high-pressure water is divided into two paths. One path of high-pressure water enters the high-pressure water jet channel 90, the rotating sleeve 80, and the rotating pipe 81 in sequence, and finally sprays downward from the high-pressure nozzle 12. Since the nozzles of the two high-pressure nozzles 12 are both set at an angle downward, and the two nozzles are oriented at opposite angles, the reaction force of the spray pushes the rotating body 8 to rotate continuously around the center of the rotating axis 14, realizing circumferential water spraying, which significantly increases the cleaning area and improves the cleaning effect on the floor.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a soap liquid channel 3 is formed between the soap dispenser 1 and the pressure relief nozzle 2, and a pressure relief water jet channel 4 is formed between the pressure regulating valve and the pressure relief nozzle 2. The outlet end of the soap liquid channel 3 is connected to the pressure relief nozzle 2. When the input water flow in the main water channel 90 flows through the pressure relief water jet channel 4 and passes through the pressure relief nozzle 2, a Venturi tube vacuum effect is generated. The soap liquid water in the soap dispenser 1 is drawn into the pressure relief nozzle 2 through the soap liquid channel 3 and then sprayed downward. Specifically, the pressure regulating valve includes a valve core 10 disposed within the valve body 9 and a knob 11 disposed on the top of the valve body 9 and capable of rotating the valve core 10. The side wall of the valve core 10 is provided with an oblong hole 101 that communicates with the main water channel 90. Rotating the knob 11 can control the communication area between the oblong hole 101 and the main water channel 90. The pressure relief nozzle 2 has a vertically arranged spray hole 21 and a horizontally arranged suction hole 22. The spray hole 21 is a Venturi tube hole that is small in the middle and large at both ends. The liquid outlet end of the soap liquid channel 3 is connected to the upper end of the spray hole 21. The valve core 10 has a pressure relief water jet channel 4 that is connected to the pressure relief nozzle 2. The lower end of the pressure relief water jet channel 4 is connected to the upper end of the spray hole 21. One end of the suction hole 22 is connected to the soap liquid channel 3 and the other end is connected to the spray hole 21. Another high-pressure water jet passes through the pressure relief water jet channel 4 and the pressure relief nozzle 2, spraying downwards. When the high-pressure water flows through the pressure relief nozzle 2, a venturi vacuum effect is generated. The soap solution in the soap dispenser 1 is drawn into the pressure relief nozzle 2 through the soap solution channel 3 and then sprayed downwards. After both water and soap solution are sprayed onto the ground, it is convenient for the floor brush to scrub the floor. This structure realizes automatic soap solution absorption, and the pressure regulating valve can adjust the water flow rate entering the pressure relief water jet channel 4, thereby controlling and regulating the pressure of the high-pressure water jet, improving the convenience of using the floor brush.

[0024] like Figure 1 and Figure 4 As shown, the local brush also includes a suction tube 6, a connector 7, and a one-way valve assembly 5. One end of the suction tube 6 extends to the bottom of the soap dispenser 1, and the other end of the suction tube 6 is inserted into one end of the connector 7. The other end of the connector 7 is inserted into the pressure relief nozzle 2. The one-way valve assembly 5 is disposed inside the connector 7. The one-way valve assembly 5 includes a ball bearing 50 and a spring 51. One end of the spring 51 abuts against the ball bearing 50 so that the ball bearing 50 always tends to block the soap liquid channel 3. When water flows through the pressure relief nozzle 2, a venturi effect is created, and the soap solution in the soap dispenser 1 is drawn into the soap channel 3, opening the one-way valve assembly 5. The soap solution then enters the pressure relief nozzle 2 and is sprayed outwards. When the spray gun is turned off, the one-way valve assembly 5 automatically resets, and the soap channel 3 is re-sealed. At this time, when the floor or wall is scrubbed with a floor brush, even under the siphon effect, the soap solution cannot push open the one-way valve assembly 5, ensuring that the soap channel 3 remains blocked, thus solving the problem of leakage when the soap solution is not in use.
