Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and in particular to a high and low pressure two-in-one cleaning device with an energy-saving and quiet mode and its usage method. Background Technology

[0002] High-pressure cleaning equipment, as a highly efficient cleaning device, is widely used in industrial and civilian fields. Traditional high-pressure cleaning equipment typically includes basic components such as an electric motor, a high-pressure pump, water pipes, a spray gun, and nozzles. The high-pressure pump pressurizes water, which is then sprayed through the nozzles to form a high-speed water jet for cleaning. However, most current high-pressure cleaning equipment cannot achieve low-pressure cleaning when the motor and pump unit are not running. This is because the water flow rate becomes very low after the pump, making it unsuitable for low-pressure cleaning or irrigation. Existing technologies also allow for low-pressure cleaning by manually switching the connection between the low-pressure inlet and outlet pipes when the machine's motor and pump unit are off. However, this requires frequent machine operation, especially if the user forgets to switch the inlet to pump water, which can cause the machine to not dispense water after startup, potentially leading to machine burn-out or being misdiagnosed as a malfunction. Summary of the Invention

[0003] Purpose of the invention: To provide a high-low pressure two-in-one cleaning device with an energy-saving and quiet mode and its usage method, so as to solve the problem that most high-pressure cleaning devices in the prior art cannot operate at low pressure when the machine is not started or require cumbersome switching, thereby achieving energy-saving and quiet cleaning.

[0004] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0005] On the one hand, the present invention provides a high and low pressure two-in-one cleaning device with an energy-saving and quiet mode, including a shell, a motor pump unit and a water pipe winding unit. The motor pump unit includes a low pressure water inlet and a high pressure water outlet, and also includes a connecting component and a control component with at least three reserved passages. The three passages are respectively a first passage connected to the water pipe winding unit, a second passage connected to the high pressure water outlet and a third passage connected to the low pressure water inlet.

[0006] The control element is movably disposed on the connecting element to selectively connect the first path with the second path or the third path;

[0007] When the control component is in the first preset position, the motor pump unit is in the open state, and the first passage and the second passage are interconnected through the internal flow channel of the control component;

[0008] When the control component is in the second preset position, the motor pump unit is in the off state, and the first passage and the third passage are interconnected through the internal flow channel of the control component.

[0009] In some possible embodiments, the first passage is located between the second passage and the third passage, the first passage is connected to the water pipe winding unit via a water supply pipe, and the third passage is connected to the low-pressure water inlet via a water supply mechanism.

[0010] In a further embodiment, the water delivery mechanism includes an inlet pipe and a low-pressure pipe, one end of the inlet pipe being connected to the third passage and the other end being connected to an external water source;

[0011] One end of the low-pressure pipe is connected to the water inlet pipe, and the other end is connected to the low-pressure water inlet.

[0012] In a further embodiment, the control element includes a valve stem and a valve core, the valve core having an internal flow channel, the valve core being disposed within the connecting member and located between the three passages;

[0013] One end of the valve stem is fixed to the valve core, and the other end is connected to the main switch.

[0014] In a further embodiment, the main switch is located on the housing, the main switch includes a knob, the knob is rotatably located on the housing, and one end of the valve stem is connected to the knob.

[0015] In a further embodiment, the valve stem is kept in contact with the main switch, which is used to control the on or off state of the motor pump unit.

[0016] In a further embodiment, the main switch is located on the valve stem.

[0017] In a further embodiment, the hose winding unit includes a hose reel and a sprinkler hose wound on the hose reel.

[0018] In a further embodiment, the cleaning equipment is a wall-mounted cleaning machine.

[0019] On the other hand, the present invention provides a method for using a high-low pressure dual-in-one cleaning device with an energy-saving and quiet mode, the method comprising the following steps:

[0020] Step 1: Connect the external water source to the motor pump unit;

[0021] Step 2: During high-pressure cleaning, the drive control unit moves from the second preset position to the first preset position. At the same time as the main switch drives the motor pump unit to turn on, the first passage and the second passage are connected to each other through the internal flow channel of the control unit. After the liquid is pressurized by the motor pump unit, it enters the water pipe winding unit from the high-pressure outlet through the second passage and the first passage in sequence, and achieves high-pressure cleaning by flowing outward through the water pipe winding unit.

[0022] Step 3: During low-pressure cleaning, the drive control unit moves from the first preset position to the second preset position. At the same time as the main switch turns off the motor pump unit, the first passage and the third passage are connected to each other through the internal flow channel of the control unit. The liquid enters the water pipe winding unit through the third passage and the first passage in sequence, and achieves low-pressure rinsing by flowing outward through the water pipe winding unit.

[0023] The beneficial effects of this invention are as follows: This application allows the cleaning equipment to be fixed in a suitable position on the wall. When the cleaning equipment is turned on, turning on the main switch simultaneously keeps the high-pressure water outlet connected to the pump outlet, and the tap water inlet connected to the pump inlet, thus achieving high-pressure cleaning. When the user only needs the ordinary garden water pipe function, there is no need to turn on the main switch. Even with the motor pump unit off, it can still achieve high-flow rinsing, watering, and other functions, and is quiet and energy-saving, meeting more user needs. The combination of high and low pressure and its integration with the garden water pipe eliminates the need for users to manually switch the inlet and outlet water paths. Simply turning the switch allows for pump start / stop and high / low pressure switching, making it convenient for users. This effectively avoids the cumbersome operation of existing technologies where low-pressure rinsing is not possible after shutdown or where users need to manually switch the inlet and outlet water paths. In particular, if the user forgets to switch the water path, the machine cannot generate high pressure, leading to the user mistakenly believing the machine is faulty and returning it.

Detailed Implementation

[0033] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1: Refer to Figures 1-2 This embodiment discloses a high-low pressure dual-in-one cleaning device with an energy-saving and quiet mode, comprising a housing 1, a pressurization motor pump unit 2 disposed within the housing 1, a water pipe winding unit, and a main switch 8 controlling the start and stop of the motor pump unit 2. The motor pump unit 2 includes a low-pressure inlet 5 and a high-pressure outlet 6, and is connected to a power cord 12. The water pipe winding unit includes a hose reel 3 and a sprinkler pipe 4 wound on the hose reel 3. Preferably, the hose reel 3 is an automatic hose reel 3 or a manual hose reel 3. The automatic hose reel 3 enables the sprinkler pipe 4 to be automatically retracted via a spring mechanism or a motor; the manual hose reel 3 retracts the sprinkler pipe 4 via a crank handle. Specifically, the water pipe winding unit also includes a nozzle 9, which is installed at the end of the sprinkler pipe 4. The sprinkler pipe 4 is slidably connected to the housing 1, allowing the position of the nozzle 9 located outside the housing 1 to be adjusted. A water supply pipe 13 is connected to the sprinkler pipe 4.

[0036] The cleaning equipment also includes a connecting member 7 with at least three reserved passages and a control member. The three passages are a first passage, a second passage, and a third passage. The control member is movably configured on the connecting member 7 to selectively connect the first passage to the second passage or the third passage, completing the high / low pressure switching and uniformly discharging water through the water pipe winding unit. The water sprayed through the water pipe winding unit can be high-pressure water or low-pressure water. Figure 3 and Figure 6 As shown, the first passage is port A, the second passage is port B, and the third passage is port C. Preferably, the connecting element 7 can be a three-way valve.

[0037] The first passage connects to the water pipe winding unit, the second passage connects to the high-pressure outlet 6, and the third passage connects to the low-pressure inlet 5. The first passage is located between the second and third passages. The first passage connects to the water pipe winding unit via a water supply pipe 13, and the third passage connects to the low-pressure inlet 5 via a water supply mechanism. The first passage is the final outlet; both high-pressure and low-pressure water enter the water pipe winding unit through the first passage. The water supply mechanism includes an inlet pipe 11 and a low-pressure pipe 14. One end of the inlet pipe 11 connects to the third passage, and the other end connects to an external water source. One end of the low-pressure pipe 14 connects to the inlet pipe 11, and the other end connects to the low-pressure inlet 5. Figures 3-5 As shown, specifically, when the first and second channels are connected, the motor pump unit 2 is in the open state, and the third channel is in the closed state. At this time, when an external water source is connected to the inlet pipe 11, it first enters the motor pump unit 2 through the low-pressure pipe 14. The pressurized water then enters the second channel from the high-pressure outlet 6, and finally is output to the water pipe winding unit through the first channel. Figures 6-8 As shown, when the first passage and the third passage are connected, the motor pump unit 2 is in the closed state, and the second passage is also in the closed state. Therefore, after the external water source is connected to the water inlet pipe 11, it directly enters the connecting member 7 through the third passage, and then outputs to the water pipe winding unit from the first passage connected to the third passage.

[0038] The control component is linked to the on / off state of the main switch 8; the control component includes a valve stem 71 and a valve core 72, the valve core 72 has an internal flow channel, the valve core 72 is located inside the connecting member 7 and between the three passages; furthermore, the valve stem 71 is linked to the on / off state of the main switch 8, that is, changing the on / off state of the main switch 8 will drive the valve stem 71 to rotate, thereby changing the water flow path inside the control component, and the main switch 8 is used to control the start and stop of the motor pump unit 2.

[0039] As a preferred embodiment, the main switch 8 is mounted on the valve stem 71. The main switch 8 is located inside the housing 1, and its start and stop are achieved by rotating the valve stem 71.

[0040] One end of the valve stem 71 is fixed to the valve core 72, and the other end is connected to the main switch 10. Specifically, by rotating the main switch 10, the valve stem 71 drives the valve core 72 to rotate, thereby changing the position of the internal flow channel and realizing the connection between the first passage and the second or third passage.

[0041] like Figure 3 As shown, when the control component is in the first preset position, the main switch 8 turns on the motor pump unit 2, and the first passage and the second passage are interconnected through the internal flow channel of the control component, so that the high-pressure liquid is sprayed outward through the water pipe winding unit.

[0042] like Figure 6 As shown, when the control component is in the second preset position, the main switch 8 shuts off the motor pump unit 2, and the first passage and the third passage are interconnected through the internal flow channel of the control component, so that low-pressure liquid is sprayed outward through the water pipe winding unit.

[0043] The main switch is located on the housing 1. The main switch 10 includes a knob, which is rotatably mounted on the housing 1. One end of the valve stem 71 is connected to the knob, and the valve stem 71 is rotatably connected to the housing 1. When the knob is rotated outside the housing 1 to the first preset position corresponding to the ON mark, the valve stem 71 also rotates, connecting the first passage to the second passage. When the knob is rotated to the second preset position corresponding to the OFF mark, the valve stem 71 rotates, connecting the first passage to the third passage. Specifically, as shown... Figure 5 and Figure 8 As shown, both the ON and OFF markings are located on housing 1 for easy viewing.

[0044] Example 2: Based on Example 1, this example discloses a high and low pressure two-in-one cleaning device with an energy-saving and quiet mode. The cleaning device is a wall-mounted cleaning machine.

[0045] Example 3: Based on Example 1, this example discloses a method for using a high-low pressure dual-function cleaning device with an energy-saving and quiet mode. The method includes the following steps:

[0046] Step 1: Connect the external water source to the motor pump unit 2, and connect the motor pump unit 2 to the power supply through the plug on the power cord 12. The external water source includes the garden water pipe. Connect the garden water pipe to the unused end of the inlet pipe 11, and open the valve of the garden water pipe to realize the water supply operation.

[0047] Step 2: During high-pressure cleaning, the drive control unit moves from the second preset position to the first preset position, causing the main switch 10 to rotate from the OFF mark to the ON mark. Simultaneously, as the main switch 8 drives the motor pump unit 2 to open, the valve core 72 rotates with the valve stem 71, causing the first and second passages to connect through the internal flow channels of the control unit. Liquid entering the inlet pipe 11 through the garden water pipe enters the motor pump unit 2 through the low-pressure pipe 14. After being pressurized by the motor pump unit 2, it flows from the high-pressure outlet 6 through the second and first passages into the water pipe winding unit, and is then sprayed outwards at high pressure. The first preset position is the initial position, i.e., the ON mark.

[0048] Step 3: During low-pressure cleaning, the drive control unit moves from the first preset position to the second preset position, causing the main switch 10 to rotate from the ON mark to the OFF mark. Simultaneously, when the main switch 8 shuts off the motor pump unit 2, the first and third passages are interconnected through the internal flow channel of the control unit. Liquid entering the inlet pipe 11 through the garden water pipe sequentially passes through the third and first passages into the water pipe winding unit, and is then sprayed outwards at low pressure. Specifically, when the external water source is still supplying water and the control unit is in the second preset position, the user can achieve low-pressure, high-flow flushing or irrigation in an ultra-energy-saving and ultra-quiet mode without turning on the machine.
