Description

Technical Field

[0001] The present application relates to the field of cleaning machines, and more particularly to a cleaning machine. Background Art

[0002] A cleaning machine is used to rinse and filter pollutants generated or invaded during the manufacturing, assembly, use and maintenance of a hydraulic system; it can also be applied to the regular maintenance and filtration of working oil to improve cleanliness, avoid or reduce failures caused by pollution, so as to ensure the high performance, high reliability and long life of hydraulic system equipment.

[0003] The cleaning machine of the related technology includes a trolley, on which there are an electric motor, a controller, a water pump and a spray gun. The controller is used to control the operation of the electric motor. The output shaft of the electric motor is connected to the pump shaft of the water pump, and the spray gun is connected to the water outlet of the water pump. When in use, the power cord of the electric motor needs to be connected to the single-phase power supply at home or the three-phase power supply in industry for power supply.

[0004] The above-mentioned related technical solutions have the following defects: when the above-mentioned cleaning machine is taken out for outdoor use, since it is difficult to find electricity outdoors and the power cord cannot be connected to the vehicle to obtain power, the above-mentioned cleaning machine cannot be used outdoors. Summary of the Invention

[0005] In order to improve the problem that it is difficult to take the cleaning machine out for outdoor operation, the present application provides a cleaning machine.

[0006] The cleaning machine provided by the present application adopts the following technical solutions:

[0007] A cleaning machine includes a cleaning machine module, and the cleaning machine module includes a bottom plate, an electric motor with a power cord, a controller, an inverter, a spray gun and a protective cover. The electric motor, the controller, the inverter and the protective cover are all arranged on the bottom plate. The controller is used to control the operation of the electric motor. The output shaft of the electric motor is used to connect to the pump shaft of an external water pump. The spray gun is used to connect to the water outlet of the external water pump. The protective cover is used to protect the controller. The power cord of the electric motor is connected to the inverter, and the inverter is used to connect to direct current.

[0008] By adopting the above technical solutions, when used outdoors, the power cord of the electric motor converts the direct current of the vehicle-mounted battery into the alternating current required by the electric motor through the inverter, so as to drive the electric motor to work normally. At the same time, the cleaning machine module has the characteristics of being small and portable, which is convenient to take the cleaning machine out for outdoor use.

[0009] Preferably, the controller includes a body with an inner cavity and multiple groups of heat dissipation fins, and the multiple groups of heat dissipation fins are sequentially arranged on the outer wall of the body.

[0010] By adopting the above technical solution, the heat dissipation fins can be regarded as a part of the body to increase the contact area between the body and the outside world and improve the heat dissipation effect of the body.

[0011] Preferably, it further includes a first driving member. Each group of heat dissipation fins includes two heat dissipation fins. One end of each heat dissipation fin is provided with a rotating shaft, and the rotating shaft is rotatably connected to the body. The first driving member is used to drive the rotating shaft to rotate. When the temperature of the controller is lower than the preset value, the first driving member is used to drive the two heat dissipation fins in the same group to rotate until they abut against each other, and the side surfaces of the two heat dissipation fins facing each other cover each other. When the temperature of the controller is higher than the preset value, the first driving member is used to drive the two heat dissipation fins in the same group to rotate towards the side away from each other.

[0012] By adopting the above technical solution, the preset value is a temperature at which the controller can work normally. When the cleaning machine is not in use or when the cleaning machine is used in a low-temperature environment such as winter, the temperature of the controller is usually lower than the preset value. At this time, the two heat dissipation fins abut against each other, which can improve the structural strength of the heat dissipation fins. When the cleaning machine is used in a high-temperature environment such as summer, the temperature of the controller is usually higher than the preset value. At this time, driving the two heat dissipation fins to rotate towards the side away from each other can increase the contact area between the heat dissipation fins and the outside world, thereby further improving the heat dissipation effect.

[0013] Preferably, the first driving member includes a plurality of torsion springs, a plurality of driving plates and a plurality of thermal expansion and contraction blocks. The plurality of torsion springs respectively correspond to the plurality of rotating shafts. The torsion springs are used to drive the two heat dissipation fins in the same group to always rotate towards the side close to each other. The plurality of driving plates respectively correspond to the plurality of rotating shafts. The driving plates are fixed on the corresponding rotating shafts and are rotatably connected to the inside of the body following the rotating shafts. Multiple groups of heat dissipation fins and the plurality of thermal expansion and contraction blocks are arranged at intervals. Both ends of the thermal expansion and contraction block are respectively used to abut against the two adjacent driving plates of the adjacent two groups of heat dissipation fins. When the temperature of the controller is lower than the preset value, the thermal expansion and contraction block does not exert force on the driving plate. When the temperature of the controller is higher than the preset value, the thermal expansion and contraction block expands and pushes the two adjacent driving plates towards the side away from each other.

[0014] By adopting the above technical solution, when the temperature of the controller is lower than the preset value, the thermal expansion and contraction block contracts and does not exert force on the driving plate. The two heat dissipation fins in the same group move to abut against each other under the action of the torsion spring. When the temperature of the controller is higher than the preset value, the thermal expansion and contraction block expands due to heat. The thermal expansion and contraction block will push the two adjacent driving plates towards the side away from each other. At this time, the two heat dissipation fins in the same group will also move towards the side away from each other, thereby increasing the contact area between the heat dissipation fins and the outside world.

[0015] Preferably, a main water-cooling channel and a plurality of secondary water-cooling channels are provided inside the body. An inlet pipe and an outlet pipe are provided on the body. Two ends of the main water-cooling channel are respectively communicated with the inlet pipe and the outlet pipe. Two ends of the secondary water-cooling channels are respectively communicated with two ends of the main water-cooling channel. The main water-cooling channel and the plurality of secondary water-cooling channels surround the inner cavity from different directions.

[0016] By adopting the above technical solution, the inlet pipe is communicated with the water outlet of the water pump, and the outlet pipe is communicated with the spray gun, so that the water pumped out by the water pump can flow through the main water-cooling channel and the plurality of secondary water-cooling channels to cool the controller by water cooling, improving the cooling effect of the controller.

[0017] Preferably, a plurality of throttling devices are further included. The plurality of throttling devices respectively correspond to the plurality of secondary water-cooling channels, and the throttling devices are used to control the on-off of the corresponding secondary water-cooling channels.

[0018] By adopting the above technical solution, after the water pump pumps water into the inlet pipe, the water will branch and flow through the main water-cooling channel and the plurality of secondary water-cooling channels. The more the number of branches, the greater the load pressure of the pump, and at the same time, the water pressure sprayed by the spray gun will also decrease. Therefore, when heat dissipation is not necessary, the throttling device can be used to block the corresponding secondary water-cooling channel, and the water flow only passes through the main water-cooling channel to cool the controller, so that the water pressure sprayed by the spray gun can be maintained in the best state.

[0019] Preferably, the throttling device includes a locking device, a throttling block and a first spring. The throttling block is slidably connected to the inside of the body along the length direction perpendicular to one end of the secondary water-cooling channel close to the main water-cooling channel. The first spring is arranged on the throttling block and drives the throttling block to always move towards the corresponding secondary water-cooling channel side to move away from the secondary water-cooling channel. The locking device is used to lock the position of the throttling block on the body. When the locking device locks the throttling block, the throttling block blocks the corresponding secondary water-cooling channel. When the locking device is unlocked, the throttling block moves away from the secondary water-cooling channel.

[0020] By adopting the above technical solution, the on-off control of the secondary water-cooling channel is realized by changing the position of the throttling block.

[0021] Preferably, the locking device includes a second spring, a pulling rope, a locking block, a lever and a driving block. The driving block is fixed on the rotating shaft closest to the corresponding water-cooling sub-channel. The driving block is movably connected within the body. The lever is rotatably connected within the body about a fulcrum. The rotational axis direction of the lever fulcrum is parallel to the axis direction of the corresponding rotating shaft. The locking block is slidably connected within the body along a direction perpendicular to the sliding direction of the flow-blocking block. A slot for inserting the end of the locking block is formed on one side surface of the flow-blocking block facing the locking block. A second spring is provided on the flow-blocking block to drive the locking block to always move towards the corresponding flow-blocking block side. Two ends of the pulling rope are respectively fixed to one end of the locking block and the lever. The other end of the lever always abuts against the corresponding driving block. The abutting position between the driving block and the lever and the connecting position between the pulling rope and the lever are respectively located on both sides of the lever fulcrum;

[0022] When two heat dissipation fins of the group of heat dissipation fins where the driving block is located abut against each other, the end of the locking block extends into the slot. When two heat dissipation fins of the group of heat dissipation fins where the driving block is located rotate towards the side away from each other, the locking block disengages from the slot.

[0023] By adopting the above technical solution, when the thermal expansion and contraction block near the rotating shaft where the driving block is located is heated and expands, the thermal expansion and contraction block drives the rotating shaft to rotate by pushing the driving plate. The rotation of the rotating shaft drives the driving block to rotate synchronously. The driving block abuts against the lever and drives the lever to rotate about the fulcrum. The end of the lever away from the driving block pulls the pulling rope, causing the locking block to move out of the slot against the elastic force of the second spring. The flow-blocking block moves out of the corresponding water-cooling sub-channel under the action of the first spring, enabling water to pass through this water-cooling sub-channel to cool this part of the position on the body, and being able to cool according to the heat generation at different positions of the actual situation of the body.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] By setting an inverter, when used outdoors, the power cord of the motor converts the direct current of the vehicle-mounted battery into the alternating current required by the motor through the inverter, thereby driving the motor to work normally. At the same time, the cleaning machine module has the characteristics of being small and portable, facilitating the cleaning machine to be taken outdoors for use.

[0026] By setting a water-cooling main channel and water-cooling sub-channels, connecting the water inlet pipe to the water outlet of the water pump and the water outlet pipe to the spray gun, enabling the water pumped out by the water pump to flow through the water-cooling main channel and several water-cooling sub-channels to cool the controller by water cooling, improving the cooling effect of the controller.

Detailed implementation manners

[0035] The following further describes the present application in detail with reference to the attached Figures 1-7 drawings.

[0036] The embodiment of the present application discloses a cleaning machine.

[0037] Referring to Figure 1 , Figure 2, A cleaning machine in this embodiment includes a cleaning machine module. The cleaning machine module includes a bottom plate 1, a motor 11 with a power cord, a controller 2, an inverter 12, a spray gun, a circuit breaker 13, and a protective cover 14. The motor 11, the controller 2, the circuit breaker 13, the inverter 12, and the protective cover 14 are all fixed on the bottom plate 1. The controller 2 is used to control the operation of the motor 11. The output shaft of the motor 11 is used to connect to the pump shaft of an external water pump. The spray gun is used to connect to the water outlet of the external water pump. The power cord of the motor 11 is connected to the inverter 12. The inverter 12 is used to connect to direct current. The circuit breaker 13 is used to quickly cut off and connect the load circuit to protect the circuit.

[0038] Referring to Figure 1 , Figure 2 , The protective cover 14 is detachably connected to the base to protect the controller 2. The protective cover 14 is arranged in an L shape. A plurality of bolts 141 are connected to the protective cover 14. One end of the bolt 141 passes through the protective cover 14 and is threadedly connected to the main body 21. When the protective cover 14 is installed on the bottom plate 1, the inner walls on both sides of the right-angle part of the protective cover 14 abut against the outer walls on both sides of one of the right angles of the bottom plate 1. The projection of the protective cover 14 on the base covers the controller 2 and the circuit breaker 13. The protective cover 14 plays a role in protecting the controller 2 and the circuit breaker 13. A plurality of placement grooves 142 are formed on the protective cover 14. The placement grooves 142 are used to place the nozzle 15 of the spray gun.

[0039] Referring to Figure 1 , Figure 2 , The cleaning machine module is small and portable, which is convenient for taking the cleaning machine outdoors for use. At the same time, the cleaning machine module requires the operator to use it with an external water pump and does not come with an external water pump separately. When used outdoors, an external coupling is used to coaxially and fixedly connect the output shaft of the motor 11 and the pump shaft. Then the spray gun is connected to the water outlet of the external water pump. Then the power cord of the motor 11 is connected to the in-vehicle battery. The power cord of the motor 11 converts the direct current of the in-vehicle battery into the alternating current required by the motor 11 through the inverter 12, so as to drive the motor 11 to work normally.

[0040] Referring to Figure 3 , Figure 4, the controller 2 includes a body 21 with a cavity 211 and multiple groups of heat dissipation fins 22. The cavity 211 is used to accommodate the electrical components inside the controller 2. The multiple groups of heat dissipation fins 22 are evenly distributed on the top surface of the body 21 along the width direction parallel to the body 21. Each group of heat dissipation fins 22 includes two heat dissipation fins 22. One end of the heat dissipation fin 22 in the width direction is fixed with a rotating shaft 221. Multiple arc grooves 212 are formed on the top surface of the body 21. The multiple arc grooves 212 are sequentially distributed on the body 21 along the width direction parallel to the body 21. The multiple rotating shafts 221 respectively correspond to the multiple arc grooves 212. The rotating shaft 221 is rotatably connected in the corresponding arc groove 212. The outer circumferential wall of the rotating shaft 221 always fits against the inner circumferential wall of the arc groove 212. The axis direction of the rotating shaft 221 is parallel to the length direction of the body 21. The two rotating shafts 221 of the same group of heat dissipation fins 22 are distributed along the width direction of the body 21, and the two arc grooves 212 corresponding to the two rotating shafts 221 are interconnected. The heat at different positions on the body 21 can be conducted to the corresponding rotating shaft 221 and heat dissipation fin 22.

[0041] Referring to Figure 3 , Figure 4 , a first driving member 23 is provided inside the body 21. The first driving member 23 is used to drive the rotating shaft 221 to rotate. The controller 2 will generate heat during use. The temperature at which the controller 2 can be used normally is a preset value. When the temperature of the controller 2 is lower than the preset value, the first driving member 23 is used to drive the two heat dissipation fins 22 of the same group to rotate until they abut against each other. At this time, the side surfaces of the two heat dissipation fins 22 facing each other are completely attached together. When the temperature of the controller 2 is higher than the preset value, the first driving member 23 drives the two heat dissipation fins 22 of the same group to rotate towards the side away from each other.

[0042] Referring to Figure 3 , Figure 4 , the heat dissipation fin 22 can be regarded as a part of the body 21 to increase the contact area between the body 21 and the outside world and improve the heat dissipation effect of the body 21. When the cleaning machine is not in use or when the cleaning machine is used in a low-temperature environment such as winter, the temperature of the controller 2 is usually lower than the preset value. At this time, the two heat dissipation fins 22 abut against each other, which can improve the structural strength of the heat dissipation fin 22. When the cleaning machine is used in a high-temperature environment such as summer, the temperature of the controller 2 is usually higher than the preset value. At this time, driving the two heat dissipation fins 22 to rotate towards the side away from each other can increase the contact area between the heat dissipation fin 22 and the outside world, thereby further improving the heat dissipation effect.

[0043] Referring to Figure 3 , Figure 4, the first driving member 23 includes a plurality of torsion springs, a plurality of driving plates 231 and a plurality of thermal expansion and contraction blocks 232. In this embodiment, the thermal expansion and contraction blocks 232 are nylon blocks. The plurality of torsion springs respectively correspond to the plurality of rotating shafts 221. The torsion springs are coaxially installed on the corresponding rotating shafts 221. When there is no external force acting on the heat dissipation fins 22 and the rotating shafts 221, the two heat dissipation fins 22 in the same group rotate towards the side close to each other under the action of the torsion springs until the side surfaces facing each other are completely attached together. At this time, the heat dissipation fins 22 are perpendicular to the body 21.

[0044] Referring to Figure 3 , Figure 4 , the plurality of driving plates 231 respectively correspond to the plurality of rotating shafts 221. A plurality of sector-shaped grooves 213 are formed in the body 21. The driving plates 231 are fixed on the outer walls of the corresponding rotating shafts 221 away from the heat dissipation fins 22. The plurality of driving plates 231 respectively correspond to the plurality of sector-shaped grooves 213. The driving plates 231 are rotatably connected to the corresponding sector-shaped grooves 213 following the rotation of the rotating shafts 221. A plurality of partition grooves 218 are also formed in the body 21. The multiple groups of heat dissipation fins 22 and the plurality of partition grooves 218 are arranged at intervals. The two ends of the partition grooves 218 are respectively communicated with two adjacent sector-shaped grooves 213. The plurality of thermal expansion and contraction blocks 232 respectively correspond to the plurality of partition grooves 218. The thermal expansion and contraction blocks 232 are movably connected in the corresponding partition grooves 218. The two ends of the thermal expansion and contraction blocks 232 are respectively used to abut against two adjacent driving plates 231 of two adjacent groups of heat dissipation fins 22.

[0045] Referring to Figure 3 , Figure 4 , when the temperature of the controller 2 is lower than the preset value, the thermal expansion and contraction blocks 232 contract and do not apply force to the driving plates 231. The two heat dissipation fins 22 in the same group move to abut against each other under the action of the torsion springs. At this time, the two driving plates 231 corresponding to the two heat dissipation fins 22 in the same group will move towards the side away from each other to approach the corresponding thermal expansion and contraction blocks 232. At this time, the two driving plates 231 abut against the groove walls on the side away from each other of the two sector-shaped grooves 213. When the temperature of the controller 2 is higher than the preset value, the thermal expansion and contraction blocks 232 expand due to heat. The thermal expansion and contraction blocks 232 will push two adjacent driving plates 231 to move towards the side away from each other. At this time, the two heat dissipation fins 22 in the same group will also move towards the side away from each other, thereby increasing the contact area between the heat dissipation fins 22 and the outside. When the two driving plates 231 abut against the groove walls on the side close to each other of the two sector-shaped grooves 213, the two heat dissipation fins 22 are opened to the maximum extent. At this time, the heat dissipation effect of the heat dissipation fins 22 is the best.

[0046] Referring to Figure 4 , Figure 5, a water-cooling main channel 24 and two water-cooling sub-channels 25 are provided inside the body 21. An inlet water pipe 261 and an outlet water pipe 262 are fixedly installed at both ends of the body 21 in the length direction. Both ends of the water-cooling main channel 24 are respectively communicated with the inlet water pipe 261 and the outlet water pipe 262, and the water-cooling main channel 24 bypasses from directly below the inner cavity 211. Both ends of the water-cooling sub-channel 25 are respectively communicated with both ends of the water-cooling main channel 24. The two water-cooling sub-channels 25 are respectively located on both sides of the water-cooling main channel 24 and respectively bypass from both sides of the inner cavity 211. The water-cooling main channel 24 and the two water-cooling sub-channels 25 surround the inner cavity 211 from three different directions. Refer to Figure 3 , Figure 5 , the inlet water pipe 261 is communicated with the outlet of the external water pump, and the outlet water pipe 262 is further communicated with the spray gun, so that the water pumped out by the external water pump can flow through the water-cooling main channel 24 and several water-cooling sub-channels 25 to cool the controller 2 by water cooling and improve the cooling effect of the controller 2.

[0047] Refer to Figure 5 , Figure 6 , two throttling devices 3 are provided on the body 21. The two throttling devices 3 respectively correspond to the two water-cooling sub-channels 25, and the throttling device 3 is used to control the on-off of the corresponding water-cooling sub-channel 25. After the external water pump pumps water into the inlet water pipe 261, the water will branch and pass through the water-cooling main channel 24 and several water-cooling sub-channels 25. The more the number of branches, the greater the load pressure of the pump, and at the same time, the water pressure sprayed by the spray gun will also decrease. Therefore, when heat dissipation is not necessary, the throttling device 3 can be used to block the corresponding water-cooling sub-channel 25, and the water flow only passes through the water-cooling main channel 24 to cool the controller 2, so that the water pressure sprayed by the spray gun can be maintained at a higher state.

[0048] Refer to Figure 5 , Figure 6 , the throttling device 3 includes a locking device 31, a throttling block 32 and a first spring 33. The length directions of both ends of the water-cooling sub-channel 25 communicated with the water-cooling main channel 24 are parallel to the width direction of the body 21. Two vertical grooves 215 are provided inside the body 21. The two vertical grooves 215 respectively correspond to the two water-cooling sub-channels 25. The bottom end of the vertical groove 215 is communicated with the corresponding water-cooling sub-channel 25. The length direction of the vertical groove 215 is parallel to the height direction of the body 21. The throttling block 32 is slidably connected in the corresponding vertical groove 215 along the length direction parallel to the vertical groove 215. The first spring 33 is located in the corresponding vertical groove 215. Both ends of the first spring 33 are respectively fixed on the top wall of the vertical groove 215 and the top surface of the throttling block 32. A limiting ring block 34 is fixed on the inner wall of the top end of the vertical groove 215. The first spring 33 passes through the limiting ring block 34 and the limiting ring block 34 will not affect the movement of the first spring 33. The first spring 33 is always in a stretched state. When there is no external force, the throttling block 32 moves toward the side away from the corresponding water-cooling sub-channel 25 under the action of the first spring 33 until it abuts against the limiting ring block 34. At this time, the throttling block 32 does not block the water-cooling sub-channel 25.

[0049] Refer to Figure 5 and Figure 6 The locking device 31 is used to lock the position of the intercepting block 32 on the main body 21. After the locking device 31 locks the intercepting block 32, the intercepting block 32 blocks the corresponding water-cooling sub-channel 25. When the locking device 31 is unlocked, the intercepting block 32 moves away from the corresponding water-cooling sub-channel 25 under the action of the first spring 33.

[0050] Refer to Figure 6 and Figure 7 The locking device 31 includes a second spring 311, a pulling rope 312, a locking block 313, a lever 314 and a driving block 315. The main water-cooling channel 24 is located at the central position in the width direction of the main body 21. Among the multiple rotating shafts 221, the two rotating shafts 221 at the outermost ends are called extreme rotating shafts 2211. The two extreme rotating shafts 2211 are respectively close to the two ends in the width direction of the main body 21 and respectively close to the two water-cooling sub-channels 25. The two water-cooling sub-channels 25 are located on both sides of the two extreme rotating shafts 2211. The two driving blocks 315 on the two locking devices 31 are respectively fixed on the two extreme rotating shafts 2211.

[0051] Refer to Figure 6 and Figure 7 The driving block 315 is located on the side of the extreme rotating shaft 2211 away from the corresponding heat dissipation fin 22 and is movably connected inside the main body 21. The lever 314 is rotatably connected inside the main body 21 around a fulcrum. The rotation axis direction of the fulcrum of the lever 314 is parallel to the axis direction of the rotating shaft 221. Two transverse grooves 216 are formed inside the main body 21. The two transverse grooves 216 respectively correspond to the two locking blocks 313. The locking blocks 313 are slidably connected in the corresponding transverse grooves 216 along the sliding direction perpendicular to the intercepting block 32. The two locking blocks 313 are respectively located on both sides of the two intercepting blocks 32. A slot 321 for inserting the end of the locking block 313 is formed on the side surface of the intercepting block 32 facing the corresponding locking block 313. The two second springs 311 respectively correspond to the two transverse grooves 216. The two ends of the second spring 311 respectively abut against the side surface of the transverse groove 216 away from the intercepting block 32 and the side surface of the corresponding locking block 313 away from the intercepting block 32. The second spring 311 is always in a compressed state. The lever 314 is located between the corresponding driving block 315 and the locking block 313. The two ends of the pulling rope 312 are respectively fixed to the end of the locking block 313 away from the intercepting block 32 and the bottom end of the lever 314. The top end of the lever 314 always abuts against the corresponding driving block 315. The abutting position of the driving block 315 and the lever 314 and the connecting position of the pulling rope 312 and the lever 314 are respectively located on both sides of the fulcrum of the lever 314. At the same time, the distance from the abutting position of the driving block 315 and the lever 314 to the fulcrum is greater than the distance from the connecting position of the pulling rope 312 and the lever 314 to the fulcrum.

[0052] Refer to Figure 6 andFigure 7 After the water pumped out by the external water pump cools the controller 2 through the main water-cooling channel 24, if the thermal expansion and contraction blocks 232 at both ends of the main body 21 in the width direction do not expand due to heat again to drive the extreme shaft 2211 to rotate by pushing the drive plate 231, at this time, the extreme shaft 2211 cannot drive the drive block 315 to move significantly, nor can it pull the pull rope 312 by pushing the lever 314 to move the locking block 313 out of the slot 321. At this time, the end of the locking block 313 is always located in the slot 321, and the intercepting block 32 blocks the corresponding secondary water-cooling channel 25. This can reduce the number of water flow branches, keep the water pressure sprayed by the spray gun at a good level, and at the same time reduce the load on the pump.

[0053] Refer to Figure 4 、 Figure 6 After the water pumped out by the external water pump cools the controller 2 through the main water-cooling channel 24, if the thermal expansion and contraction blocks 232 at both ends of the main body 21 in the width direction still expand due to heat to drive the extreme shaft 2211 to rotate by pushing the drive plate 231, it indicates that the water flowing through one main water-cooling channel 24 cannot cool the controller 2 well. At the same time, the controller 2 is the key to controlling the normal operation of the motor 11, so it is necessary to stabilize the controller 2 first. Refer to Figure 6 、 Figure 7 At this time, the rotation of the extreme shaft 2211 drives the drive block 315 to rotate. The drive block 315 abuts against the top of the lever 314 to drive the top of the lever 314 to rotate towards the vertical groove 215 side, and then drives the pull rope 312 at the bottom of the lever 314 to move away from the intercepting block 32 side. The pull rope 312 drives the locking block 313 to overcome the elastic force of the second spring 311 to move the locking block 313 out of the slot 321. At the same time, the principle of the lever 314 is also used, so that the drive block 315 can drive the lever 314 to rotate more easily. At this time, the intercepting block 32 loses the locking of the locking block 313 and moves away from the secondary water-cooling channel 25 under the action of the first spring 33. The water flow can flow through the secondary water-cooling channel 25, thereby cooling each position of the main body 21 and improving the cooling effect of the controller 2.

[0054] Refer to Figure 3 、 Figure 5 In order to make the intercepting block 32 block the secondary water-cooling channel 25 again, a force-applying block 35 is fixed on the side of the intercepting block 32 away from the inner cavity 211. Two straight grooves 217 are opened on the outer wall of one side of the main body 21 in the length direction. The two straight grooves 217 respectively correspond to the two force-applying blocks 35. The straight grooves 217 communicate with the corresponding vertical grooves 215. The force-applying block 35 is slidably connected to the corresponding straight groove 217 along the sliding direction parallel to the intercepting block 32. The intercepting block 32 always blocks the straight groove 217 to prevent the water in the secondary water-cooling channel 25 from flowing out through the straight groove 217.

[0055] The implementation principle of a cleaning machine according to an embodiment of the present application is as follows: The operator connects the water inlet pipe 261 to the water outlet of an external water pump, and the water outlet pipe 262 to a spray gun, so that the water pumped out by the external water pump can flow through the main water-cooling channel 24 and several auxiliary water-cooling channels 25. The throttling device 3 can judge the heating degree of the controller 2 to control whether to throttle the auxiliary water-cooling channel 25, so that the controller 2 achieves an appropriate cooling effect. At the same time, the heat dissipation fins 22 can also open as the temperature of the controller 2 rises, improving the heat dissipation and cooling effect.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
