Description

Technical Field

[0001] The present application relates to the field of spray cleaning machines, and in particular to a high-safety high-pressure cleaning machine. Background Art

[0002] A cleaning machine is a device used to clean the surface of objects. It removes impurities such as dirt and oil stains through high-pressure water flow, ultrasound or other technologies. Cleaning machines are widely used in various industries.

[0003] A high-pressure cleaning machine consists of a plunger pump and a motor. The motor is the power source for the plunger pump, a core component responsible for generating high-pressure water. The plunger pump is connected to the spray gun via a hose, which then sprays the liquid. However, in actual use, the rapid flow rate of the liquid from the spray gun can lead to safety hazards if the gun is accidentally activated, which requires improvement. Summary of the Invention

[0004] In order to reduce the potential safety hazards of high-pressure cleaners, the present application provides a high-safety high-pressure cleaner.

[0005] This application provides a high-safety high-pressure cleaning machine, which adopts the following technical solutions:

[0006] A high-safety high-pressure cleaning machine comprises a frame and a cleaning machine body, the cleaning machine body comprising a pump body arranged 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 being provided with a push switch, the push switch being used to control the start of the spray gun, the spray gun being provided with a nozzle, the nozzle being provided with a drainage channel for spraying liquid, the drainage channel outlet being provided with a diverter plate, the diverter plate being provided with a diversion hole for spraying liquid; the nozzle being provided with a protective sleeve, the protective sleeve being coaxially rotated with the nozzle, the protective sleeve being provided with a connecting channel, the connecting channel being used to connect to the drainage channel, the inner wall of the connecting channel being provided with a closing plate, the closing plate being provided with a drainage hole, the drainage hole being used to connect to the diversion hole.

[0007] By adopting the above technical solution, a protective cover is provided, which is used to adjust the water outlet and close the nozzle. When the spray gun needs to be stopped, the press switch for controlling the water outlet is turned off, and the protective cover is rotated to make the drainage hole and the diversion hole misaligned, thereby closing the nozzle. In this way, the accidental touch of the spray gun when it is used again later is reduced, and the overall safety is improved through the double-layer protection of the press switch and the protective cover.

[0008] Optionally, the frame is provided with a fixed sleeve, the fixed sleeve is provided with a fixed groove for the nozzle to be embedded, a fixed screw is provided on the side of the fixed groove wall close to the bottom of the fixed groove, the fixed screw is provided with a rotating block, the rotating block is threadedly connected to the fixed screw, and a fixed spring is provided at the bottom of the fixed groove, the end of the fixed spring away from the bottom of the fixed groove is used to resist the rotating block, the elastic force of the fixed spring limits the rotating block from moving in the direction close to the bottom of the fixed groove, and the rotating block is used to resist the protective sleeve.

[0009] By adopting the above technical solution, in actual use, there is a situation where the user puts the spray gun away after turning off the water flow from the nozzle by pressing the switch. In this case, the protective cover loses its due protective function and increases the risk of subsequent use. Therefore, a fixed cover, a fixed screw and other components are provided. When the user puts the spray gun away, 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, so that the protective cover of the spray gun is automatically closed during the placement process, further improving the overall safety.

[0010] Optionally, the fixed screw includes a smooth portion and a screw portion, the smooth portion is located on the 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.

[0011] By adopting the above technical solution, a smooth portion and a screw portion 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 provision of the smooth portion causes the rotating block to stop rotating when it rotates to the desired position, and there is only a tendency to move in the vertical direction. This reduces the situation where the protective sleeve rotates and the drainage hole and the diversion hole are connected due to the rapid rotation of the rotating block when the spray gun is taken out, thereby improving overall safety.

[0012] 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.

[0013] By adopting the above technical solution, 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 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. 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.

[0014] Optionally, the nozzle is provided with a clamping strip, and a plurality of the clamping strips are provided along the axis of the nozzle, and a clamping groove is formed between adjacent clamping strips. The inner wall of the protective sleeve is provided with elastic protruding teeth, and the elastic protruding teeth are used to be embedded in the clamping groove.

[0015] 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 accidents or when the liquid passes through the diversion hole and the drainage hole. Therefore, elastic protruding teeth are provided, and the elastic protruding teeth are used to embed into the snap-fit groove to improve the stability of the protective sleeve and reduce the situation where the protective sleeve rotates accidentally.

[0016] Optionally, a placement block is provided on the side wall of the spray gun, the placement block is provided with a placement groove, and the frame is provided with a clamping block, and the clamping block is used to be embedded in the placement groove.

[0017] By adopting the above technical solution, a placement groove is provided, in which the clamping block of the spray gun is embedded, thereby improving the stability of the spray gun when it is placed and improving the overall safety.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The protective cover is set up. The double protection of the press switch and the protective cover improves the overall safety and reduces the situation of accidental touch when the spray gun is used again. Secondly, the closing plate of the protective cover is used to cooperate with the diverter plate to adjust the flow rate, which is convenient for high-pressure cleaning.

[0020] 2. A fixed sleeve, a fixed screw and other components are provided. When the user holds the spray gun, the weight of the spray gun causes the protective sleeve to press the rotating block, and the rotating block rotates to drive the protective sleeve to rotate, thereby automatically closing the protective sleeve of the spray gun during placement, further improving the overall safety;

[0021] 3. A limit block and a limit groove are set. The limit block is used to embed in the limit groove. When the protective sleeve moves, the rotating block moves toward 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 aligns with the limit groove. At this time, the gravity of the spray gun causes the limit block to embed in the limit groove. In this way, the rotation of the rotating block drives the rotation of the protective sleeve, thereby facilitating the closure 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.

[0029] The present application is further described in detail below with reference to the accompanying drawings and examples.

[0030] The embodiment of the present application discloses a high-safety high-pressure cleaning machine. Figures 1 to 6 The cleaning machine body 2 includes a frame 1, a cleaning machine body 2, and a control panel 3. The cleaning machine body 2 is mounted on the frame 1. The control panel 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 mounted on the frame 1, a driving member 22 for driving the pump body 21, and a spray gun 23 connected to the pump body 21 by a hose. The spray gun 23 is provided with a press switch 4 for controlling the activation of the spray gun 23.

[0031] The side wall of the spray gun 23 is provided with a placement block 19, and the placement block 19 is provided with a placement groove 20. The frame 1 is provided with a clamping block, and the clamping block is used to fit 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 to the 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 provided along the axis of the nozzle 5, and a clamping groove 8 is formed between adjacent clamping strips 7. The inner wall of the protective sleeve 6 is provided with a clearance groove 9, and the bottom of the clearance groove 9 is provided with an elastic protruding tooth 10, and the elastic protruding tooth 10 is used to fit into the clamping groove 8. The protective sleeve 6 is provided with a limit block 11, and the limit block 11 is located on the side of the protective sleeve 6 away from the nozzle 5.

[0032] The nozzle 5 is provided with a drainage channel 12 for liquid ejection. The outlet of the drainage channel 12 is provided with a diverter plate 13, which is provided with a diverter hole 14 for liquid ejection. The protective sleeve 6 is provided with a connecting channel 15, which is used to connect with the drainage channel 12. The inner wall of the connecting channel 15 is provided with a closing plate 16, which is provided with a drainage hole 17, which is used to connect with the diverter hole 14.

[0033] When the protective sleeve 6 is rotated until the drainage hole 17 is completely connected to the diversion hole 14, the elastic protruding teeth 10 abut the clamping strip 7 on one side; when the protective sleeve 6 is rotated until the drainage hole 17 is misaligned with the diversion hole 14, the elastic protruding teeth 10 abut the clamping strip 7 on the other side.

[0034] The frame 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 embedded. A fixing screw 25 is provided on the side of the fixing groove 24 near the bottom of the fixing groove 24. The fixing screw 25 includes a smooth portion 252 and a screw portion 251. The smooth portion 252 is located on the side of the screw portion 251 near the bottom of the fixing groove 24.

[0035] The fixed screw 25 is sleeved with a fixed spring 26, which is connected to the bottom wall of the fixed groove 24. The screw portion 251 is provided with a rotating block 27, which is threadedly connected to the screw portion 251. The rotating block 27 slides on the smooth portion 252. The end of the fixed spring 26 away from the bottom of the fixed groove 24 abuts the rotating block 27. The elastic force of the fixed spring 26 restricts the rotating block 27 from moving toward the bottom of the fixed groove 24. The rotating block 27 is provided with a limiting groove 28, which is located on the side of the rotating block 27 away from the fixed spring 26. The limiting groove 28 is for the limiting block 11 to be inserted into.

[0036] When the fixing spring 26 is in a normal state, the rotating block 27 is located on the screw portion 251. When the spray gun 23 is placed and the spray gun 23 moves toward the frame, the nozzle 5 and the protective sleeve 6 are inserted into the fixed groove 24. The downward pressure of the protective sleeve 6 causes the limit block 11 to abut against the rotating block 27. If the drainage hole 17 is completely connected to the diverter hole 14 at this time, the downward movement of the spray gun 23 causes the limit block 11 to be inserted into the limit groove 28. The rotating block 27 rotates along the thread of the screw portion 251 and drives the limit block 11 to rotate until the rotating block 27 moves to the smooth end. If the drainage hole 17 and the diverter hole 14 are not completely connected at this time, the downward movement of the spray gun 23 causes the limit block 11 to abut against the rotating block 27 and causes the rotating block 27 to move toward the bottom of the fixed groove 24 until the limit block 11 is inserted into the limit groove 28. Then, the rotating block 27 rotates and drives the protective sleeve 6 to rotate.

[0037] In actual use, the protective sleeve 6 and the nozzle 5 may be provided with warning signs, which are used to assist the user in judging the degree of rotation of the protective sleeve 6 , thereby facilitating the judgment of the connection status between the drainage hole 17 and the diversion hole 14 .

[0038] The implementation principle of a high-safety high-pressure cleaning machine in an embodiment of the present application is as follows: in actual use, the opening and closing of the spray gun 23 is controlled by pressing the switch 4, and the protective cover 6 is used to adjust the flow rate of the spray gun 23 and to protect the spray gun 23 when it is placed, thereby reducing the situation where the spray gun 23 is started due to accidental touch. The double-layer protection of the press switch 4 and the protective cover 6 improves the overall safety and reduces the situation where the press switch 4 is accidentally touched when placed.

[0039] When the spray gun 23 needs to be placed, the protective sleeve 6 and the nozzle 5 are embedded in the fixed groove 24, and 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 possibility of accidental touch after placement and improving the safety of subsequent use.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
