DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0040] As shown in Figures 1 to 5 The steam high-pressure cleaning mixing device provided by the embodiment of the application comprises a main machine 1, a connecting pipe 11 is fixed on one side of the main machine 1, a handle 2 is fixed at the top end of the connecting pipe 11, a first connecting block 24 is fixed at one end of the handle 2, a spray head 21 is fixed on the side of the first connecting block 24 away from the handle 2, a button 22 is arranged on the side of the handle 2, and a rotary switch is arranged at the top end of the main machine 1.

[0041] The connecting seat 31 is fixed outside the spray head 21, a plurality of groups of baffles 3 are arranged at equal intervals on the outer side of the connecting seat 31, each group of baffles 3 is symmetrically arranged with two baffles 3, a rotating groove 23 is formed on one side of the bottom end of the handle 2, and a rotating wheel 34 is rotatably connected in the rotating groove 23.

[0042] The rotating wheel 34 can drive the plurality of groups of baffles 3 to expand when the rotating wheel 34 rotates, and the baffles 3 can shield the front of the handle 2 after expansion.

[0043] After the equipment needing ventilation is used for a long time, more dust will accumulate inside, and some equipment in the environment will also accumulate oil stains inside. At this time, the dirt inside the equipment will be difficult to clean, so high-temperature steam will be used to clean the dirt. Before cleaning, the host 1 is pulled to the position of use, and then the wires of the host 1 are connected to the power supply at the current position. The cleaning liquid required for cleaning is filled into the inside of the host 1. The host 1 is internally provided with a high-pressure steam generator and a cleaning liquid conveying mechanism. Then, the equipment to be cleaned is disassembled from the shell to expose the area to be cleaned. Then the worker wears gloves and holds the handle 2. Then the worker holds the handle 2 and extends the end of the nozzle 21 into the position inside the equipment to be cleaned. The host 1 is started to generate steam by rotating the knob switch, and the steam is transmitted to the inside of the handle 2 through the connecting pipe 11. The handle 2 sprays steam outward through the nozzle 21. After the steam is sprayed, it contacts the inside of the equipment, which can melt the oil stains on the equipment and also flush away other dirt. The flushed dirt flows down with the condensed water. After steam cleaning, different liquids can be selected by the knob to output different aspects of cleaning of the equipment.

[0044] When cleaning some suspended equipment below, the head of the nozzle 21 is usually held in an upward position. At this time, there is a high probability that the condensed water from the equipment will drop onto the worker's skin, causing burns. However, placing the nozzle 21 at an angle for cleaning will create dead angles, so the nozzle 21 needs to be in a vertical state and shield the condensed water. In the initial state, the baffle 3 is in a state of gathering together, and at this time the baffle 3 is attached to the outside of the nozzle 21. When shielding the condensed water is needed, the rotating wheel 34 is actuated to drive the baffle 3 to rotate. At this time, the baffle 3 is separated from the surface of the nozzle 21 and is rotated to a vertical angle with the nozzle 21. At this time, a plurality of baffles 3 can form a complete disc, which can be referred to Figure 1 、 Figure 2 The disc formed by the baffle 3 can shield in front of the handle 2. When the nozzle 21 is in a vertical state and cleans the bottom of the equipment, the condensed water will be contacted and shielded by the baffle 3, which can prevent the condensed water from contacting the worker's skin and causing burns. When the rotating wheel 34 is actuated in the opposite direction after use, the baffle 3 can be reset.

[0045] As shown in Figures 1 to 8 , one side of the baffle 3 is fixed with a second connecting rod 352, and a plurality of installation grooves 311 are evenly arranged on the outside of the connecting seat 31. A second connecting block 35 is rotatably connected in the installation groove 311. The bottom end of the second connecting rod 352 is rotatably connected in the second connecting block 35.

[0046] The rotating wheel 34 drives the second connecting block 35 to rotate;

[0047] When the baffle 3 is in the storage state, the top ends of the baffle 3 can interfere with other baffles 3, and the second connecting rod 352 and the second connecting block 35 are rotationally connected, so that when the baffles 3 interfere with each other, the second connecting rod 352 can be rotated to adaptively adjust the angle between the baffles 3. When the baffle 3 needs to be rotated to the working position, the second connecting block 35 can be rotated by the rotating wheel 34. When the second connecting block 35 is rotated by 90° from the initial angle in the installation slot 311, the second connecting block 35 can drive the baffle 3 to rotate to the state perpendicular to the nozzle 21. In this way, the baffle 3 can be conveniently rotated.

[0048] As shown in Figures 1 to 10 , the bottom end of the second connecting rod 352 extends into the interior of the second connecting block 35, the side surface of the bottom end of the second connecting rod 352 is fixed with a rotating plate 355, the interior of the second connecting block 35 is provided with a cavity for the rotation of the rotating plate 355, one side of the rotating plate 355 is fixed with a second spring 356, and the other end of the second spring 356 is fixedly connected with the second connecting block 35;

[0049] The baffle 3 is rotated to drive the rotating plate 355 to rotate in the cavity through the second connecting rod 352;

[0050] When the baffle 3 is stored, the baffle 3 can interfere with the corners of other baffles 3, and the baffle 3 is pushed to rotate under the interaction of the baffles 3. The baffle 3 drives the second connecting rod 352 to rotate, and the second connecting rod 352 rotates in the interior of the second connecting block 35. The second connecting rod 352 drives the rotating plate 355 to rotate, and the rotating plate 355 pushes the second spring 356 to be compressed. When the baffle 3 is unfolded, the baffles 3 are separated, and the elastic force of the second spring 356 pushes the rotating plate 355 to rotate in the opposite direction to drive the second connecting rod 352 to rotate. The second connecting rod 352 drives the baffle 3 to reset, so that the corners of the plurality of baffles 3 can be in contact, and the baffles 3 can be adaptively aligned and automatically rotated.

[0051] As shown in Figures 1 to 7 , the interior of the first connecting block 24 is slidably connected with a moving frame 33, the bottom end of the side of the moving frame 33 away from the baffle 3 is fixed with a tooth rack 331, the top end of the rotating wheel 34 is provided with a plurality of teeth, and the side of the tooth rack 331 close to the rotating wheel 34 is also provided with a plurality of teeth. The rotating wheel 34 and the tooth rack 331 are connected through the meshing of the teeth;

[0052] The tooth rack 331 drives the moving frame 33 to move, and the moving frame 33 drives the second connecting block 35 to rotate;

[0053] In the initial state, the baffle 3 is in close contact with the surface of the nozzle 21. When the baffle 3 needs to be rotated, the rotating wheel 34 is rotated to drive the toothed rack 331 through the top teeth, the toothed rack 331 is driven to pull the moving frame 33 to move towards the rotating wheel 34, and when the baffle 3 is in a vertical state with the nozzle 21, the toothed rack 331 and the rotating wheel 34 are in a state of Figure 6 , which can facilitate the adjustment of the state of the baffle 3.

[0054] As shown in Figures 1 to 9 , a plurality of gear racks 351 are fixed on the side of the second connecting block 35 close to the moving frame 33, and a plurality of toothed plates 332 are fixed on the side of the moving frame 33 close to the second connecting block 35 at equal intervals, and the toothed plates 332 are connected with the second connecting block 35 through the gear racks 351;

[0055] When the moving frame 33 is pulled, the moving frame 33 pulls the toothed plates 332 to move, and the toothed plates 332 can drive the second connecting block 35 to rotate through the gear racks 351 when moving, and at this time, the second connecting block 35 can be simultaneously driven to rotate through a plurality of toothed plates 332, so as to simultaneously change the angles of a plurality of baffles 3, thereby making the second connecting block 35 more convenient to form a disc body.

[0056] As shown in Figures 1 to 9 , the two sides of the mounting groove 311 are provided with rotating holes 312, and the two sides of the second connecting block 35 are fixed with rotating columns 353, the rotating columns 353 are rotatably connected in the rotating holes 312, the outer part of the rotating column 353 is fixed with a coil spring 354, and the other end of the coil spring 354 is fixedly connected with the connecting seat 31;

[0057] When the second connecting block 35 rotates, the rotating column 353 rotates in the rotating hole 312, and at the same time, the coil spring 354 is tightened when the second connecting block 35 rotates, the coil spring 354 is tightened to the maximum degree when the baffle 3 is in a vertical state with the nozzle 21, and the elastic force of the coil spring 354 assists the rotation of the second connecting block 35 when the baffle 3 is stored, so that it is more labor-saving to rotate the rotating wheel 34 during the storage of the baffle 3.

[0058] As shown in Figures 1 to 7 , the bottom end of the rotating wheel 34 is fixed with a push block 342, the two sides of the rotating wheel 34 are provided with telescopic holes 343, the inside of the telescopic hole 343 is fixed with a first spring 344, the other end of the first spring 344 is fixed with a fixed ball 345, the fixed ball 345 is slidably connected in the telescopic hole 343, and the two sides of the rotating groove 23 are provided with recesses;

[0059] The maximum rotation angle of the rotating wheel 34 is 90° when the push block 342 is pushed, and the recesses are arranged at positions where the fixed ball 345 can rotate to the maximum angle in the rotating groove 23.

[0060] When the rotating wheel 34 needs to be poked, in order to facilitate the rotation of the rotating wheel 34, a poking block 342 is arranged at the bottom end of the rotating wheel 34, and the end of the poking block 342 is far away from the center position of the rotating wheel 34. The force for poking the poking block 342 can be amplified through the rotating wheel 34 to the toothed rack 331 through the principle of lever, and through the amplified force, the toothed rack 331 can be pulled more easily to make the plurality of baffles 3 rotate at the same time. After rotation, in order to be pulled by the toothed rack 331 through the second connecting block 35 due to the reverse force of the coil spring 354, the rotating wheel 34 needs to be limited, so the first spring 344 and the fixed ball 345 are arranged in the telescopic hole 343. In the initial state, the poking block 342 is directed towards the button 22, at this time the first spring 344 pushes the fixed ball 345 to be clamped in the current groove, and when the moving frame 33 needs to be unfolded, the poking block 342 will rotate 90° and be directed towards the nozzle 21. At this time, the first spring 344 pushes the fixed ball 345 to be clamped in the groove on the other side, so as to limit the rotating wheel 34. Because the first springs 344 on both sides are in the eccentric position of the rotating wheel 34, the elastic force of the first springs 344 will be amplified through the principle of lever, and the coil spring 354 is in the center position of the second connecting block 35. The elastic force of the first spring 344 after amplification is greater than the elastic force of the plurality of coil springs 354, so as to ensure that the rotating wheel 34 will not be rotated during use.

[0061] As shown in Figures 1 to 8 The outer part of the first connecting block 24 is sleeved with a protective shell 32, and the two sides of the protective shell 32 are fixedly provided with first connecting rods 321. The two sides of the rotating wheel 34 are fixedly provided with rotating shafts 341, and the upper parts of the rotating shafts 341 are engagedly connected with rotating rods 323. The two sides of the handle 2 are provided with sliding grooves 231, and the ends of the first connecting rods 321 away from the protective shell 32 are slidingly connected in the sliding grooves 231.

[0062] The rotating rods 323 can drive the first connecting rods 321 to slide when the rotating rods 323 rotate.

[0063] When the baffle 3 catches the condensed water, the connection between the baffle 3 and the second connecting block 35 is prone to water leakage. Therefore, a protective shell 32 is arranged at the connection between the baffle 3 and the second connecting block 35. In the initial state, the protective shell 32 is outside the first connecting block 24 and does not contact the baffle 3. When the baffle 3 needs to be unfolded, the rotating wheel 34 rotates, which simultaneously drives the rotating shaft 341 to rotate. The rotating shaft 341 drives the first gear 325 to rotate in the opposite direction. The first gear 325 drives the first connecting rod 321 to slide in the direction of the baffle 3 inside the sliding groove 231 through the rotating rod 323. At this time, the first connecting rod 321 pushes the protective shell 32 to extend from the outside of the first connecting block 24 to the direction of the baffle 3. After the protective shell 32 extends, it is attached to the connection between the second connecting block 35 and the baffle 3. When the condensed water caught by the baffle 3 slides to the direction of the second connecting block 35, it will pass through the gap and enter the inside of the protective shell 32. The protective shell 32 can temporarily store the condensed water. When the baffle 3 is reset after use, the protective shell 32 is also reset to the outside of the first connecting block 24. At this time, the relative movement between the protective shell 32 and the first connecting block 24 can squeeze the condensed water in the protective shell 32 to the outside, thereby realizing the temporary storage of the condensed water by the protective shell 32 and preventing the condensed water from flowing to the surface of the skin of the worker through the gap.

[0064] As shown in Figure 4 , the end of the first connecting rod 321 away from the protective shell 32 is fixed with a sliding column 322, and one side of the rotating rod 323 is provided with a sliding hole 324. The sliding column 322 is slidingly connected in the inside of the sliding hole 324;

[0065] When the rotating rod 323 needs to drive the first connecting rod 321 to move, the sliding column 322 slides in the inside of the sliding hole 324. The rotating rod 323 drives the sliding column 322 to move through the sliding hole 324. The inside space of the sliding hole 324 can provide a moving space for the sliding column 322 when the rotating rod 323 rotates.

[0066] As shown in Figure 4 , the inside of the protective shell 32 is inlaid with a sealing ring 326. The inside of the sealing ring 326 can be tightly attached to the outside of the first connecting block 24;

[0067] The sealing ring 326 in the inside of the protective shell 32 can stay between the first connecting block 24 and the protective shell 32. At this time, the gap between the protective shell 32 and the first connecting block 24 can be filled with the sealing ring 326, thereby preventing the protective shell 32 from leaking when storing the condensed water.
