Description

[Technical Field]

[0002] This utility model relates to the field of window cleaning robot technology, specifically to a dual-nozzle control flow channel and a window cleaning machine. [Background Technology]

[0004] Most existing window cleaning machines use a dual-nozzle design to improve cleaning efficiency and coverage. The two nozzles work together to quickly remove stains and dust from windows, enhancing cleaning results. This design is widely used in cleaning large glass curtain walls or residential windows.

[0005] However, existing window cleaning machines with dual nozzles mostly use two pumps controlled independently, which may lead to inconsistent spray volume and affect the uniformity of cleaning. In addition, the dual pump system increases the failure rate and maintenance cost. Therefore, a single-control flow channel system is needed to ensure uniform spray and reduce maintenance difficulty.

Detailed Implementation Methods

[0033] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Specific embodiments, combined with Figures 1 to 3 As shown, the technical solution of this utility model is further explained. A dual-nozzle control flow channel is applied to a water spray cleaning device. It includes a water pump 10 with a motor that can control the water path in both forward and reverse directions. Two water pipes for forming a water path are provided between the water pump 10 and the water tank 20. One side of the water pump 10 is connected to the water tank 20 through a first water pipe 31, and the other side of the water pump 10 is connected to the water tank 20 through a second water pipe 32.

[0035] The first water pipe 31 is provided with a first control valve 311 for controlling the flow of water on the side near the water tank 20. A first tee connector 312 is provided between the first control valve 311 and the water pump 10. A third water pipe 33 is provided on one side of the first tee connector 312 and connected to the first nozzle 41. A third control valve 331 for controlling the flow of water is provided on the third water pipe 33 between the first tee connector 312 and the first nozzle 41.

[0036] The second water pipe 32 is provided with a second control valve 321 for controlling the flow of water on the side near the water tank 20. A second three-way connector 322 is provided between the second control valve 321 and the water pump 10. A fourth water pipe 34 connected to the second nozzle 42 is provided on one side of the second three-way connector 322. A fourth control valve 341 for controlling the flow of water is provided on the fourth water pipe 34 between the second three-way connector 322 and the second nozzle 42.

[0037] The first control valve 311, the second control valve 321, the third control valve 331, and the fourth control valve 341 can plan the flow direction of the water path when the water pump 10 rotates forward and backward, ensuring that the water pump 10 can spray water from the first nozzle 41 and the second nozzle 42 through the forward and reverse motor.

[0038] Furthermore, one side of the first three-way connector 312 is connected to the water tank 20 via the first water pipe 31, one side is connected to the water pump 10 via the first water pipe 31, and one side is connected to the first nozzle 41 via the third water pipe 33; one side of the second three-way connector 322 is connected to the water tank 20 via the second water pipe 32, one side is connected to the water pump 10 via the second water pipe 32, and one side is connected to the second nozzle 42 via the fourth water pipe 34. The first three-way connector 312 can connect the water pump 10, the water tank 20, and the first nozzle 41, and the second three-way connector 322 can connect the water pump 10, the water tank 20, and the first nozzle 42, ensuring the continuity of the water circuit. This facilitates the water pump 10's motor rotating in both forward and reverse directions, coordinating with the first control valve 311, the second control valve 321, the third control valve 331, and the fourth control valve 341 to spray water from the first nozzle 41 or the second nozzle 42 for use.

[0039] Furthermore, the first control valve 311, the second control valve 321, the third control valve 331, and the fourth control valve 341 are all independently controlled. This independent control of the four valves ensures the continuity of the water circuit and guarantees the normal operation of the water pump 10 during forward and reverse rotation of the motor.

[0040] like Figure 2As shown, this direction is the direction of water flow when the motor of the water pump 10 is rotating forward. The first control valve 311 and the fourth control valve 341 are open, and the second control valve 321 and the third control valve 331 are closed, so that the water pump 10 draws water out through the first water pipe 31, pumps it through the first control valve 311 to the water pump 10 for transfer, and flows through the second water pipe 32 to the second three-way connector 322. Then, through the third water pipe 33 and the fourth control valve 341, the water is transmitted to the second nozzle 42 for use.

[0041] like Figure 3 As shown, this direction is the water flow direction when the motor of the water pump 10 reverses. The first control valve 311 and the fourth control valve 341 are closed, and the second control valve 321 and the third control valve 331 are open, so that the water pump 10 draws water out through the second water pipe 32, pumps it to the water pump 10 for transfer through the second control valve 321, and flows through the first water pipe 31 to the first three-way connector 312. Then, it is transmitted through the fourth water pipe 34 and the third control valve 331 to the first nozzle 41 for use.

[0042] Optionally, when the water pump 10 rotates forward to pump water, the first control valve 311 and the fourth control valve 341 control the water flow to be connected, while the second control valve 321 and the third control valve 331 control the water flow to be blocked; when the water pump 10 rotates in reverse to pump water, the second control valve 321 and the third control valve 331 control the water flow to be connected, while the first control valve 311 and the fourth control valve 341 control the water flow to be blocked.

[0043] In this embodiment, the first control valve 311, the second control valve 321, the third control valve 331, and the fourth control valve 341 are all one-way valves. The fact that all four control valves are one-way valves allows water to flow from the first nozzle 41 or the second nozzle 42 when the motor rotates in either direction, reducing the need for external control devices.

[0044] Furthermore, the first control valve 311 and the second control valve 321 are both directed from the water tank 20 to the water pump 10, the third control valve 331 is directed from the first three-way connector 312 to the first nozzle 41, and the fourth control valve 341 is directed from the second three-way connector 322 to the second nozzle 42. The orientation of the four control valves facilitates the opening and closing of the water circuit when the water pump 10 rotates forward or reverse, and also facilitates the formation of the water circuit and enables normal water spraying.

[0045] Furthermore, the first water pipe 31, the second water pipe 32, and the water tank 20 can form a stable water path. Water can be stably absorbed between the first water pipe 31, the second water pipe 32, and the water tank 20, facilitating the water spraying operation.

[0046] A window cleaning machine includes a dual-nozzle control flow channel as described above. By employing the dual-nozzle control flow channel, the window cleaning machine can utilize a single water pump to operate two nozzles, ensuring the normal operation of the machine and providing convenience for its use and maintenance.

[0047] Furthermore, the first nozzle 41 is used to dispense water from one end of the window cleaning machine, and the second nozzle 42 is used to dispense water from the other end of the window cleaning machine. The first nozzle 41 and the second nozzle 42 are independently controlled. Independent control of the first nozzle 41 and the second nozzle 42 enables normal water spraying while ensuring the stable operation of the window cleaning machine.

[0048] The working principle of this embodiment is as follows:

[0049] This utility model proposes a dual-nozzle control channel and a window cleaning machine. The dual-nozzle control channel can control the spraying of water from both ends of the nozzles through a water pump 10, enabling the window cleaning machine using the dual-nozzle control channel to spray water from both ends, thereby improving the working efficiency of the window cleaning machine. The specific principle is as follows:

[0050] When the motor of water pump 10 is rotating in the forward direction, the first control valve 311 and the fourth control valve 341 are in normal flow, while the second control valve 321 and the third control valve 331 are closed, so that water pump 10 draws water out through the first water pipe 31, pumps it to the water pump 10 transfer station through the first control valve 311, and flows through the second water pipe 32 to the second three-way connector 322, and then through the third water pipe 33 to the second nozzle 42 for use through the fourth control valve 341.

[0051] When the motor of water pump 10 reverses, the first control valve 311 and the fourth control valve 341 are blocked, while the second control valve 321 and the third control valve 331 are open normally. This allows water pump 10 to draw water through the second water pipe 32, pump it through the second control valve 321 to the water pump 10 for transfer, and then through the first water pipe 31 to the first three-way connector 312. Finally, the water is transmitted through the fourth water pipe 34 and the third control valve 331 to the first nozzle 41 for use.
