Description

Technical Field

[0001] This application relates to the field of spray washing machines, and more particularly to a high-safety high-pressure cleaning machine. Background Art

[0002] A cleaning machine is a device used to clean the surface of an object, which removes dirt, oil stains and other impurities through high-pressure water flow, ultrasonic waves or other technologies. Cleaning machines are widely used in various industries.

[0003] The cleaning machine includes a plunger pump and a motor. The motor is the power source for driving the plunger pump. The plunger pump is the core component of the high-pressure cleaning machine and is responsible for generating high-pressure water. The plunger pump is connected to the spray gun through a hose, and the liquid is ejected through the spray gun. However, in actual use, since the flow rate of the liquid ejected from the spray gun is relatively fast, there is a safety hazard when the spray gun switch is accidentally touched, which needs to be improved. Summary of the Invention

[0004] In order to reduce the safety hazards of high-pressure cleaning machines, this application provides a high-safety high-pressure cleaning machine.

[0005] A high-safety high-pressure cleaning machine provided by this application adopts the following technical solutions: A high-safety high-pressure cleaning machine includes a frame and a cleaning machine body. The cleaning machine body includes a pump body disposed on the frame, a driving member for driving the pump body to operate, and a spray gun connected to the pump body by a hose. The spray gun is provided with a push switch for controlling the start of the spray gun. The spray gun is provided with a nozzle, and the nozzle is provided with a drainage channel for liquid ejection. A flow splitter plate is provided at the outlet of the drainage channel, and the flow splitter plate is provided with flow splitting holes for liquid ejection; the nozzle is provided with a protective sleeve, the protective sleeve rotates coaxially with the nozzle, the protective sleeve is provided with a communication channel for communicating the drainage channel, and a closing plate is provided on the inner wall of the communication channel. The closing plate is provided with a diversion hole for communicating the flow splitting holes.

[0006] By adopting the above technical solutions, a protective sleeve is provided. The protective sleeve is used to adjust the water outlet and close the nozzle. When it is necessary to stop using the spray gun, the push switch for controlling the water outlet is closed, and the protective sleeve is rotated so that the diversion hole is misaligned with the flow splitting hole, thereby closing the nozzle. In this way, the situation of accidental touch when the spray gun is used again later is reduced, and the overall safety is improved through the double protection of the push switch and the protective sleeve.

[0007] Optionally, the frame is provided with a fixing sleeve, the fixing sleeve is provided with a fixing groove for the nozzle to be embedded, a fixing screw is provided on the side of the fixing groove wall close to the bottom of the fixing groove, the fixing screw is provided with a rotating block, the rotating block is threadedly connected to the fixing screw, and a fixing spring is provided at the bottom of the fixing groove, the end of the fixing spring away from the bottom of the fixing groove is used to resist the rotating block, the elastic force of the fixing spring limits the rotating block from moving in a direction close to the bottom of the fixing groove, and the rotating block is used to resist the protective sleeve.

[0008] By adopting the above technical solution, in actual use, there is a situation where the user closes the water flow from the nozzle by pressing the switch and then puts the spray gun aside. In this case, the protective cover loses its due protective effect and increases the danger of subsequent use. Therefore, a fixed cover, a fixed screw and other components are provided. When the user stops the spray gun, the weight of the spray gun causes the protective cover to press the rotating block, and the rotation of the rotating block drives the protective cover to rotate, thereby automatically closing the protective cover of the spray gun during the placement process, further improving the overall safety.

[0009] Optionally, the fixed screw includes a smooth portion and a screw portion, the smooth portion is located on a side of the screw portion close to the bottom of the fixed groove, and the rotating block is threadedly connected to the screw portion; when the rotating block moves to the smooth portion, the fixed spring is in a compressed state.

[0010] By adopting the above technical solution, a smooth part and a screw part are provided. When the drainage hole and the diversion hole of the protective sleeve are misaligned with the movement of the rotating block, the protective sleeve does not need to continue to rotate. Therefore, the setting of the smooth part makes the rotating block stop rotating when it rotates to the required position, and there is only a tendency to move in the vertical direction. This reduces the situation where the protective sleeve rotates due to the rapid rotation of the rotating block when the spray gun is taken out, causing the drainage hole and the diversion hole to be connected, thereby improving the overall safety.

[0011] Optionally, the protective sleeve is provided with a limit block, which is located on the side of the protective sleeve away from the nozzle, and the rotating block is provided with a limit groove, which is located on the side of the rotating block away from the fixed spring, and the limit groove is for the limit block to be embedded; when the rotating block moves toward the smooth part, the rotating block rotates and drives the fixed sleeve to rotate until the drainage hole and the diversion hole are misaligned.

[0012] By adopting the above technical scheme, a limit block and a limit groove are provided, and the limit block is used to be embedded in the limit groove. When the protective sleeve moves, the rotating block moves toward the direction close to the bottom of the fixed groove, and due to the setting of the fixed screw, the rotating block rotates during the movement; as the rotating block rotates, the limit block is aligned with the limit groove, and at this time, the gravity of the spray gun causes the limit block to be embedded in the limit groove. In this way, the rotation of the rotating block drives the rotation of the protective sleeve, thereby facilitating the closing of the drainage channel by the closing plate, so that the protective sleeve automatically closes the drainage channel when the spray gun is prevented from hitting the frame, thereby improving the overall safety.

[0013] Optionally, the nozzle is provided with clamping strips. A plurality of clamping strips are arranged along the axis of the nozzle, and clamping grooves are formed between adjacent clamping strips. Elastic convex teeth are arranged on the inner wall of the protective sleeve, and the elastic convex teeth are used to be embedded into the clamping grooves.

[0014] By adopting the above technical solution, during the actual use of the spray gun, there is a situation where the protective sleeve rotates due to an accident or when liquid passes through the shunt holes and the drainage holes. Therefore, elastic convex teeth are provided. The elastic convex teeth are used to be embedded into the clamping grooves to improve the stability of the protective sleeve and reduce the accidental rotation of the protective sleeve.

[0015] Optionally, a placement block is arranged on the side wall of the spray gun. The placement block is provided with a placement groove, and the frame body is provided with a clamping block, and the clamping block is used to be embedded into the placement groove.

[0016] By adopting the above technical solution, a placement groove is provided for the clamping block of the spray gun to be embedded into, so as to improve the stability of the spray gun during placement and enhance the overall safety.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: 1. A protective sleeve is provided. Through the double protection of the pressing switch and the protective sleeve, the overall safety is improved, and the situation of accidental touch when the spray gun is used again later is reduced. Secondly, the closing plate of the protective sleeve is used to cooperate with the shunt plate to adjust the flow rate, which is convenient for high-pressure cleaning; 2. Components such as a fixing sleeve and a fixing screw are provided. When the user places the spray gun, the weight of the spray gun causes the protective sleeve to press the rotating block, and the rotation of the rotating block drives the rotation of the protective sleeve, so that the protective sleeve of the spray gun is automatically closed during the placement process, further improving the overall safety; 3. A limiting block and a limiting groove are provided. The limiting block is used to be embedded into the limiting groove. When the protective sleeve moves, the rotating block moves towards the direction close to the bottom of the fixing groove, and due to the setting of the fixing screw, the rotating block rotates during the movement; as the rotating block rotates, the limiting block aligns with the limiting groove. At this time, the gravity of the spray gun causes the limiting block to be embedded into the limiting groove. In this way, it is convenient for the rotation of the rotating block to drive the rotation of the protective sleeve, so as to facilitate the closing of the drainage channel by the closing plate, so that the protective sleeve automatically closes the drainage channel when the spray gun is placed on the frame body, improving the overall safety.

Detailed implementation manners

[0025] The following further elaborates on this application in conjunction with the drawings and embodiments.

[0026] The embodiment of this application discloses a high - safety high - pressure cleaning machine. Referring to Figures 1 to 6 , it includes a frame body 1, a cleaning machine body 2 and a control board 3. The cleaning machine body 2 is arranged on the frame body 1, and the control board 3 is used to control the opening and closing of the cleaning machine body 2. The cleaning machine body 2 includes a pump body 21 arranged on the frame body 1, a driving member 22 for driving the pump body 21 to operate, and a spray gun 23 connected to the pump body 21 by a hose. The spray gun 23 is provided with a pressing switch 4, and the pressing switch 4 is used to control the start of the spray gun 23.

[0027] The side wall of the spray gun 23 is provided with a placement block 19, the placement block 19 is provided with a placement groove 20, and the frame body 1 is provided with a clamping block for embedding into the placement groove 20. The spray gun 23 is provided with a nozzle 5, and the outer wall of the nozzle 5 is rotatably connected with a protective sleeve 6. The outer wall of the nozzle 5 is provided with a clamping strip 7, and a plurality of clamping strips 7 are arranged along the axis of the nozzle 5. A clamping groove 8 is formed between adjacent clamping strips 7. The inner wall of the protective sleeve 6 is provided with a relief groove 9, and the bottom of the relief groove 9 is provided with an elastic convex tooth 10 for embedding into the clamping groove 8. The protective sleeve 6 is provided with a limiting block 11, and the limiting block 11 is located on the side of the protective sleeve 6 away from the nozzle 5.

[0028] The nozzle 5 is provided with a drainage channel 12 for liquid ejection. A flow splitting plate 13 is provided at the outlet of the drainage channel 12, and the flow splitting plate 13 is provided with flow splitting holes 14 for liquid ejection. The protective sleeve 6 is provided with a communication channel 15 for communicating with the drainage channel 12. A closing plate 16 is provided on the inner wall of the communication channel 15, and the closing plate 16 is provided with a drainage hole 17 for communicating with the flow splitting holes 14.

[0029] When the protective sleeve 6 is rotated until the drainage hole 17 is completely communicated with the flow splitting hole 14, the elastic convex teeth 10 abut against the clamping strip 7 on one side; when the protective sleeve 6 is rotated until the drainage hole 17 is misaligned with the flow splitting hole 14, the elastic convex teeth 10 abut against the clamping strip 7 on the other side.

[0030] The frame body 1 is provided with a fixing sleeve 18, and the fixing sleeve 18 is provided with a fixing groove 24 for the nozzle 5 to be inserted. On one side of the groove wall of the fixing groove 24 close to the bottom of the fixing groove 24, a fixing screw 25 is provided. The fixing screw 25 includes a smooth part 252 and a screw part 251, and the smooth part 252 is located on the side of the screw part 251 close to the bottom of the fixing groove 24.

[0031] A fixing spring 26 is sleeved on the fixing screw 25. The fixing spring 26 is connected to the bottom wall of the fixing groove 24. A rotating block 27 is provided on the screw part 251. The rotating block 27 is threadedly connected to the screw part 251. The rotating block 27 slides on the smooth part 252. One end of the fixing spring 26 away from the bottom of the fixing groove 24 abuts against the rotating block 27, and the elastic force of the fixing spring 26 restricts the rotating block 27 from moving towards the bottom of the fixing groove 24. The rotating block 27 is provided with a limiting groove 28, and the limiting groove 28 is located on the side of the rotating block 27 facing away from the fixing spring 26. The limiting block 11 is embedded in the limiting groove 28.

[0032] When the fixing spring 26 is in a normal state, the rotating block 27 is located on the screw part 251; when the spray gun 23 is placed, during the process of the spray gun 23 moving towards the frame body, the nozzle 5 and the protective sleeve 6 are inserted into the fixing groove 24, and the protective sleeve 6 is pressed downwards so that the limiting block 11 abuts against the rotating block 27. If the drainage hole 17 is completely communicated with the flow splitting hole 14 at this time, the downward movement of the spray gun 23 causes the limiting block 11 to be embedded in the limiting groove 28, and the rotating block 27 rotates along the thread of the screw part 251 and drives the limiting block 11 to rotate until the rotating block 27 moves to the smooth end. If the drainage hole 17 and the flow splitting hole 14 are not completely communicated at this time, the downward movement of the spray gun 23 causes the limiting block 11 to press tightly against the rotating block 27 and causes the rotating block 27 to move towards the bottom of the fixing groove 24 until the limiting block 11 is embedded in the limiting groove 28, and then the rotating block 27 rotates to drive the protective sleeve 6 to rotate.

[0033] In actual use, warning signs can be set on the protective sleeve 6 and the nozzle 5. The warning signs are used to assist the user in judging the rotation degree of the protective sleeve 6, so as to facilitate judging the communication state of the drainage hole 17 and the flow splitting hole 14.

[0034] The implementation principle of a high - security high - pressure cleaner in an embodiment of this application is as follows: In actual use, the opening and closing of the spray gun 23 is controlled by pressing the switch 4. The protective sleeve 6 is used to adjust the flow rate of the spray gun 23 and provide protection when the spray gun 23 is placed, reducing the situation where the spray gun 23 is started due to accidental touch. Through the double - layer protection of the pressing switch 4 and the protective sleeve 6, the overall safety is improved, and the situation where the pressing switch 4 is accidentally touched during placement is also reduced.

[0035] When the spray gun 23 needs to be placed, when the protective sleeve 6 and the nozzle 5 are inserted into the fixing groove 24, the pressing of the protective sleeve 6 causes the rotating block 27 to rotate and drives the protective sleeve 6 to close the diversion hole 14, thereby reducing the situation of accidental touch after placement and improving the safety of subsequent use.

[0036] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
