Detailed Implementation

[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0028] Unless otherwise explicitly specified and limited, the terms "setup," "installation," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms based on the specific circumstances.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0031] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0032] like Figure 2 and Figure 3 As shown, this embodiment provides an integrated high-pressure cleaner, including a motor 20, a water pump 10, a power switch 30, a pressure switch 40, a button 31, a capacitor 70, and a switch box 60. Motor 20 is located on one side of water pump 10, and drives water pump 10 to pump water. Switch box 60 is located above water pump 10 and motor 20, and switch box 60 is fixedly connected to both water pump 10 and motor 20. Power switch 30 and pressure switch 40 are located inside switch box 60 and are electrically connected. A first connecting hole and a second connecting hole 61 are opened on the bottom surface of switch box 60. Water pump 10 is equipped with overflow valve 50. The valve core 51 of overflow valve 50 passes through the first connecting hole and abuts against the switch contact 41 of pressure switch 40. Motor 20 is electrically connected to pressure switch 40 and power switch 30 after passing through the second connecting hole 61 via a connecting wire. An opening is opened on the top surface of switch box 60, and button 31 is located inside the opening. Button 31 is connected to power switch 30 and is used to turn power switch 30 on or off. Capacitor 70 is located inside switch box 60 and is connected in parallel with motor 20.

[0033] The integrated high-pressure washer provided in this embodiment integrates the power switch 30 and the pressure switch 40 into a single switch box 60. This reduces the number of switch boxes 60 in existing washeres to a single switch box 60, simplifying the structure, lowering costs, and saving assembly time. The first and second connecting holes 61 on the switch box 60 are used for wiring connections to the water pump 10 and the motor 20, respectively. This ensures that all wiring of the washer is completed within the switch box 60, eliminating exposed wiring and avoiding the risk of wire breakage or leakage.

[0034] Furthermore, in existing cleaning machines, the power switch 30 and pressure switch 40 are located on the motor 20 and water pump 10 respectively, and the distance between them is relatively large, requiring wiring connections, which leads to numerous and messy wiring harnesses. Specifically, for example... Figure 4 As shown, the power switch 30, motor 20, and pressure switch 40 are connected in series. The valve core 51 of the overflow valve 50 in the pump abuts against the pressure switch 40. When the water pressure in the pump exceeds a set threshold, the valve core 51 pushes the pressure switch 40 to open, thereby de-energizing the entire circuit and stopping the motor 20. Since the power switch 30 and pressure switch 40 are far apart and their wiring harness is exposed, for electrical safety, they are connected via a first wire 5 and a second wire 6. To ensure the safety of the motor 20, the second motor lead 23 of the negative terminal of the motor 20 should not be extended too far. Therefore, the motor 20 is connected to the first wire 5 via the connection terminal 4 of the second motor lead 23. One end of the first wire 5 is connected to the second motor lead 23, and the other end is connected to the pressure switch 40 via the connection terminal 4. In addition, the power switch 30 and the pressure switch 40 are far apart. Therefore, the power switch 30 and the pressure switch 40 are electrically connected by connecting the two ends of the second wire 6 to the connection terminals 4 of the power switch 30 and the pressure switch 40 respectively. The presence of the first wire 5 and the second wire 6 will increase the assembly difficulty and safety risks.

[0035] like Figure 5 As shown, Figure 5 The electrical schematic diagram of the integrated high-pressure washer provided in this embodiment shows that the power switch 30 includes a first switch 32 and a second switch 33. The first switch 32 is connected in series with the positive terminal of the motor 20. The pressure switch 40 includes a single-pole double-throw switch. The negative terminal of the motor 20 is connected to the moving end 42 of the pressure switch 40. One of the stationary ends 43 of the pressure switch 40 is connected in series with the second switch 33 of the power switch 30. The moving end 42 of the pressure switch 40 abuts against the valve core 51 of the overflow valve 50. When the valve core 51 of the overflow valve 50 moves towards the moving end 42 of the pressure switch 40 under the water pressure drive of the water pump 10, it pushes the moving end 42 of the pressure switch 40, so that the moving end 42 of the pressure switch 40 is connected to the other stationary end, thus completing the power-off of the washer.

[0036] Because in this embodiment, such as Figure 5 and Figure 6As shown, the positive lead of motor 20 is the first motor lead 22, and the negative lead of motor 20 is the second motor lead 23. The first motor lead 22 connects the positive terminal of motor 20 to the first switch 32 of power switch 30, and the second motor lead 23 connects the negative terminal of motor 20 to the moving end 42 of pressure switch 40. Since both power switch 30 and pressure switch 40 are located in switch box 60, switch box 60 protects the motor leads, preventing them from direct contact with the outside environment. Therefore, it is appropriate to extend the motor leads to a certain length. Therefore, the second motor lead 23 of the negative terminal of the motor 20 has a third terminal 21, and the moving end 42 of the pressure switch 40 has a fourth terminal 45. The motor 20 and the pressure switch 40 are electrically connected through the third terminal 21 and the fourth terminal 45. By directly connecting the second motor lead 23 and the pressure switch 40 through the third terminal 21 and the fourth terminal 45, the first wire 5 can be omitted, the number of wires can be reduced, and the overall structure can be simplified.

[0037] Furthermore, in this embodiment, the power switch 30 is located above the pressure switch 40, and the power switch 30 and the pressure switch 40 are connected via terminals. Specifically, the second switch 33 of the power switch 30 has a first terminal 34, and the stationary end 43 of the pressure switch 40 connected to the second switch 33 has a second terminal 44. The second switch 33 and the pressure switch 40 are electrically connected via the first terminal 34 and the second terminal 44. By directly connecting the power switch 30 and the pressure switch 40 via the first terminal 34 and the second terminal 44, the second wire 6 is omitted, further simplifying the wiring harness and the overall structure.

[0038] Capacitor 70 is located in switch box 60 and is electrically connected to motor 20 through capacitor connection line 90.

[0039] A wire hole 62 is provided on the side between the top and bottom surfaces of the switch box 60. The switching power supply is electrically connected to the external power supply through the power connection wire 80 passing through the wire hole 62.

[0040] Furthermore, to facilitate the maintenance or disassembly and installation of the power switch 30 and the pressure switch 40, one of the side walls 63 between the top and bottom surfaces of the switch box 60 is detachably mounted on the switch box 60. When the power switch 30 or the pressure switch 40 needs maintenance or replacement, the side wall 63 can be removed to maintain or replace the power switch 30 or the pressure switch 40 in the switch box 60.

[0041] Specifically, such as Figure 7As shown, the switch box 60 has a buckle 632 on one of the detachable side wall 63 and the adjacent side wall 64 of the detachable side wall 63, and a slot 631 on the other of the detachable side wall 63 and the adjacent side wall 64 of the detachable side wall 63. In this embodiment, the slot 631 is located on the detachable side wall 63, and the buckle 632 is located on the adjacent side wall 64. The side wall 63 and the adjacent side wall 64 are connected by the buckle 632 and the slot 631.

[0042] In summary, the integrated high-pressure washer provided in this embodiment can reduce the number of switch boxes 60, simplify the structure, avoid exposed wiring harnesses to prevent safety accidents, and reduce the number of wiring harnesses, thus avoiding messy wiring connections.

[0043] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
