[0015] (III) Beneficial effects The present invention provides a switch box for a high-pressure cleaning machine, which has the following beneficial effects: (1) The present invention connects a water gun to the water outlet of the high-pressure water pump, and the motor drives the high-pressure water pump to rotate, so that high-pressure water is ejected from the water gun to complete cleaning. When the water gun is closed, the internal pressure of the high-pressure water pump increases, and the push rod set in the high-pressure water pump is extended under the action of pressure. Because the push rod abuts against the arc-shaped guide block, the first slider is pushed, the spring is compressed, and then the second slider is pushed. The second slider presses the micro switch to cut off the power, the motor is in a standby state, and the high-pressure water pump stops working; when the high-pressure cleaning machine is in a standby state, the experimenter can open the water gun to discharge the high-pressure water in the high-pressure water pump, the pressure in the high-pressure water pump decreases, the push rod retreats, the first slider retreats, the second slider retreats, the micro switch is turned on, and the high-pressure cleaning machine is in a working state again; when the high-pressure cleaning machine is in a working state, the experimenter can freely adjust the start and close of the main switch through the lever. When the main switch is started, water flows into the high-pressure water pump from the water inlet. Under the action of the impeller, the high-pressure water is transmitted from the water outlet to the water gun to complete the cleaning operation. This method can effectively control the startup, shutdown and standby of the device, and complete the cleaning operation conveniently.

[0016] (2) The present invention provides a circumferentially arranged impeller on the impeller of the high-pressure water pump. The impeller has two sections. The first section of the impeller forms an angle of 20 degrees with the axial direction of the transmission shaft. The second section of the impeller is connected to the first section of the impeller. The second section of the impeller forms an angle of 10 degrees with the axial direction of the transmission shaft. Compared with upright impellers, inclined impellers can better avoid the reaction force of the impeller during rotation, and the two-section distribution of impellers can effectively expand the contact area with the water flow, so that the water flow in and out of the water inlet can be better guided to drive the impeller to rotate. This design can effectively increase the service life of the impeller and make the impeller more efficient during operation.

[0017] (3) The present invention sets an arc-shaped guide block at the water inlet of the high-pressure water pump, and a narrow channel is formed between the arc-shaped guide block and the water inlet. The narrow channel accelerates the flow rate of water. Under the action of Bernoulli's principle, the flow rate of water is accelerated. When the flow rate of water is accelerated, a low-pressure area is formed, and the inside of the high-pressure water pump is a high-pressure area. Therefore, the water in the high-pressure area converges to the low-pressure area. Under the action of this device, more water can be driven and sprayed toward the impeller. Better rotation auxiliary thrust is provided to the impeller, and the performance of the high-pressure water pump is optimized.

[0018] (4) The present invention provides a cooling mechanism on the outside of the motor, wherein the cooling shell contains coolant, the spiral pipe is immersed in the coolant, and the spiral pipe is connected to the cooler. The cooler cools the motor, so that the motor can operate more efficiently and stably. BRIEF DESCRIPTION OF THE DRAWINGS

The first slider 21, the micro switch 3, and the trigger mechanism 2 can be placed on the fixing plate 14, and the fixing plate 14 plays a supporting role.

[0030] Furthermore, a second opening 12 and a third opening 13 are provided on the housing 1 , and the second opening 12 and the third opening 13 are both provided adjacent to the main switch 5 .

[0031] Among them, the high-pressure cleaning machine has a power cord, which is connected to the main switch 5 through the second opening 12, and the power cord is connected to the motor 7.

[0032] exist Figures 1 to 10 In an optional embodiment, the trigger mechanism 2 includes a first slider 21, a second slider 22 and a spring 23, wherein the first slider 21 is arranged at one end of the fixed plate 14, and the first slider 21 has an arc-shaped guide block 24 on the side adjacent to the first opening 11, and the arc-shaped guide block 24 is arranged adjacent to the first opening 11.

[0033] Further, the micro switch 3 is arranged at the other end of the fixing plate 14. The trigger mechanism 2 is arranged adjacent to the micro switch 3, one end of the spring 23 is connected to the first slider 21, the other end of the spring 23 is connected to the second slider 22, the second slider 22 is connected to the micro switch 3, the first slider 21 triggers the spring 23, the spring 23 triggers the second slider 22, the second slider 22 triggers the micro switch 3, and the main switch 5 is arranged at the lower side of the micro switch 3.

[0034] It should be noted that when the first slider 21 receives the impact of the push rod 63, the movement transfers force and energy to the spring 23. The spring 23 absorbs the energy from the first slider 21 and then transfers the force to the second slider 22. Then the second slider 22 pushes the button of the micro switch 3 to cut off the power and put the motor 7 in standby state.

[0035] Furthermore, the main switch 5 includes a lever 51, one end of which is connected to the main switch 5, and the other end of which is disposed outside the housing 1. The experimenter can freely turn the main switch 5 on / off by swinging the lever 51.

[0036] exist Figures 1 to 10 In an optional embodiment, the high-pressure water pump 6 includes a water inlet 61, a water outlet 62, a push rod 63 and an impeller 64. One end of the push rod 63 is connected to the high-pressure water pump 6. It should be noted that a limit block is also provided on one end of the push rod 63 located in the high-pressure water pump 6. The limit block can prevent the push rod 63 from being separated from the high-pressure pump 6 when it is extended. A sealing ring is also provided at the connection between the push rod 63 and the high-pressure water pump 6. The other end of the push rod 63 passes through the first opening 11 and abuts against the arc-shaped guide block 24. The push rod 63 is used to push the first slider 21 to move. A streamlined guide block 65 is provided at the middle end of the water inlet 61. A narrow channel 66 is formed between the streamlined guide block 65 and the water inlet 61. The narrow channel 66 accelerates the flow rate of the water. Based on the Bernoulli principle, the low-pressure area at the narrow channel 66 attracts more water inside the high-pressure water pump 6 to be ejected.

[0037] It should be noted that under the action of Bernoulli's principle, the water flow velocity is accelerated. When the water flow velocity is accelerated, a low-pressure area will be formed, and the inside of the high-pressure water pump 6 is a high-pressure area. Therefore, the water in the high-pressure area converges towards the low-pressure area. Under the action of this device, more water can be driven and sprayed toward the impeller 64.

[0038] exist Figures 1 to 10 In an optional embodiment, the output end of the motor 7 is connected to the transmission shaft 71, the transmission shaft 71 is connected to the impeller 64, the motor 7 drives the impeller 64 to rotate, the impeller 64 has a wheel blade 67, the wheel blade 67 has two sections, the first section of the wheel blade 67 is at an angle of 20 degrees to the axial direction of the transmission shaft 71, the second section of the wheel blade 67 is connected to the first section of the wheel blade 67, and the second section of the wheel blade 67 is at an angle of 10 degrees to the axial direction of the transmission shaft 71.

[0039] It should be noted that the inclined wheel blade 67 can withstand a smaller reaction force of the water flow than the upright blade, so as to rotate better. At the same time, driven by the water flow, it can work more efficiently.

[0040] Furthermore, there are six wheel blades 67 , and the six wheel blades 67 are distributed in a circular row around the transmission shaft 71 .

[0041] exist Figures 1 to 10 In an optional embodiment, the motor 7 has a stator 72 and a rotor 73 , the stator 72 is connected to the inner wall of the outer shell of the motor 7 , and the rotor 73 is connected to the transmission shaft 71 .

[0042] Furthermore, a connecting plate 74 is provided inside the motor 7, and the connecting plate 74 is connected to the transmission shaft 71. The connecting plate 74 is used to fix the transmission shaft 71.

[0043] Furthermore, the motor 7 has two bearings 75, both of which are connected to the transmission shaft 71, and one of the bearings 75 is connected to the connecting plate 74. The bearings 75 can make the transmission shaft 71 rotate better.

[0044] exist Figures 1 to 10 In an optional embodiment, the cooling mechanism 8 is disposed at the outer end of the motor 7 .

[0045] It should be noted that the cooling mechanism 8 includes a cooling shell 81 and a spiral pipe 82 . The cooling shell 81 is connected to the outer end of the motor 7 . There is coolant in the cooling shell 81 , and the spiral pipe 82 is immersed in the coolant.

[0046] Furthermore, the cooling mechanism 8 includes a cooler 83 , the cooler 83 is connected to the cooling shell 81 , and the spiral pipe 82 is connected to the cooler 83 via a straight pipe 84 .

[0047] The switch box for a high-pressure cleaning machine of the present invention comprises the following specific steps: By connecting a water gun to the water outlet 62 of the high-pressure water pump 6, the motor 7 drives the high-pressure water pump 6 to rotate, so that the high-pressure water flow is ejected from the water gun to complete the cleaning. When the water gun is closed, the internal pressure of the high-pressure water pump 6 increases, and the push rod 63 is connected to the high-pressure water pump 6. Therefore, under the action of high pressure, the push rod 63 in the high-pressure water pump 6 is pushed out, and because the push rod 63 abuts against the arc-shaped guide block 24, the first slider 21 is pushed, the spring 23 is compressed, and then the second slider 22 is pushed. The second slider 22 presses the micro switch 3 to cut off the power, the motor 7 is in a standby state, and the high-pressure water pump 6 stops working; when the high-pressure cleaning machine is in a standby state, the experimenter can turn on the water gun to The high-pressure water in the high-pressure water pump 6 is discharged, the pressure in the high-pressure water pump 6 is reduced, the push rod 63 retreats, the first slider 21 retreats, the second slider 22 retreats, the micro switch 3 is turned on, and the high-pressure cleaning machine is in working state again; when the high-pressure cleaning machine is in working state, the experimenter can freely adjust the start and close of the main switch 5 through the lever 51. When the main switch 5 is started, water flows into the high-pressure water pump 6 from the water inlet 61. Under the action of the impeller 64, the high-pressure water is transmitted to the water gun from the water outlet 62 to complete the cleaning operation. This method can effectively control the start, close and standby of the device, and conveniently complete the cleaning operation.

[0048] The impeller 64 in the high-pressure water pump 6 is provided with a circumferentially arranged wheel blade 67, the wheel blade 67 has two sections, the first section of the wheel blade 67 is at an angle of 20 degrees to the axial direction of the transmission shaft 71, and the second section of the wheel blade 67 is connected to the first section of the wheel blade 67, and the second section of the wheel blade 67 is at an angle of 10 degrees to the axial direction of the transmission shaft 71. Compared with the upright wheel blade 67, the inclined wheel blade 67 can better avoid the reaction force of the impeller 64 when it rotates, and the two-section distribution of the wheel blade 67 can effectively expand the contact area with the water flow, so that the water flow in and out of the water inlet 61 can be better guided to drive the impeller 64 to rotate. This design can effectively increase the service life of the impeller 64 and make the impeller 64 more efficient when working.

[0049] By setting an arc-shaped guide block 24 at the water inlet 61 of the high-pressure water pump 6, a narrow channel 66 is formed between the arc-shaped guide block 24 and the water inlet, and the narrow channel 66 accelerates the flow rate of the water. Under the action of the Bernoulli principle, the flow rate of the water is accelerated. When the flow rate of the water is accelerated, a low-pressure area will be formed, and the inside of the high-pressure water pump 6 is a high-pressure area. Therefore, the water in the high-pressure area converges to the low-pressure area, and the water gathered near the water inlet 61 can flow to the impeller along with the water entering the water inlet 61, and the impeller 64 has a certain inclination angle, which can be better rotated with the assistance of the water flow. Under the action of this device, more water can be driven and sprayed toward the impeller 64. Better rotation auxiliary thrust is provided to the impeller 64, and the performance of the high-pressure water pump 6 is optimized.

[0050] By arranging a cooling mechanism 8 on the outside of the motor 7, a cooling liquid is contained in the cooling shell 81, the spiral pipe 82 is immersed in the cooling liquid, and the spiral pipe 82 is connected to the cooler 83. The cooler 83 realizes cooling of the motor 7, so that the motor 7 can operate more efficiently and stably.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
