Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to an integrated high-pressure water jet cleaning machine. Background Art

[0002] A high-pressure water jet cleaning machine uses high-pressure water to clean dirt from surfaces. It typically consists of a high-pressure water pump, water pipes, a spray gun, and a control system. The high-pressure water pump is the machine's core component, increasing the pressure of the water source to generate a high-pressure water flow. The water pipes connected to the high-pressure water pump deliver the high-pressure water flow and are typically made of pressure-resistant and wear-resistant materials to ensure they can withstand the pressure of the high-pressure water flow. The spray gun, connected to the water pipe, sprays the high-pressure water flow. The spray gun can typically adjust the flow rate and spray pattern of the water, and different spray guns can be used for different cleaning tasks, such as washing cars, floors, and walls. The control system is used to control the start and stop functions of the cleaning machine.

[0003] High-pressure water jet cleaning machines have the advantages of high cleaning efficiency, good cleaning effect, and simple operation. They are indispensable equipment in the modern cleaning industry. In order to meet different cleaning tasks, the existing cleaning machines are generally equipped with very long water pipes, but there is a problem of inconvenient storage. The current method of storing water pipes is to coil the water pipes and hang them on the handle of the cleaning machine with a rope. However, this storage method can usually only store water pipes of shorter lengths, and each time the cleaning machine is used, the rope needs to be untied and the water pipes need to be straightened. After use, the water pipes need to be manually coiled and tied and then hung on the handle of the cleaning machine, which makes it inconvenient to use. Another method of storing water pipes is to separately equip a winding device for winding. Although this can store longer water pipes, when using the cleaning machine, two devices need to be moved, one is the cleaning machine and the other is the winding device, which is still not convenient enough.

[0004] Therefore, how to design an integrated high-pressure water jet cleaning machine that is simple and convenient to use, saves time and effort, and can improve cleaning efficiency is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the existing method of storing the water pipe of the cleaning machine, which is either to wrap it in a circle and then hang it on the handle of the cleaning machine, or to need to be equipped with a separate winding device, resulting in inconvenient operation or inconvenience in movement, thereby providing an integrated high-pressure water jet cleaning machine that is simple and convenient to use, saves time and effort, and can improve cleaning efficiency.

[0006] To this end, the utility model provides an integrated high-pressure water jet cleaning machine, comprising:

[0007] A high-pressure pump, an engine, a fuel tank, a water spray pipe retracting device, a water spray gun, and a frame; the frame has a bottom plate, the high-pressure pump, the engine, and the fuel tank are fixedly mounted above the bottom plate, the water spray pipe retracting device is fixedly mounted below the bottom surface of the bottom plate, and the water spray gun is pluggably arranged on the frame;

[0010] It also includes a reeling structure, which is arranged on the water pipe reeling device. When the water pipe is pulled outward to be released from the disc, force is stored. When the water pipe is loosened back, the water pipe can be locked. When the water pipe is pulled again and loosened back, the elastic force can be released to reel the water pipe back onto the disc.

[0011] As a preferred solution, the retracting structure includes:

[0012] a notched ratchet, fixedly mounted on the top outer wall of a cylindrical member located on one side of the disc body and fixedly connected to the disc body, having two rows of ratchet teeth with a notch between the two rows of ratchet teeth; the interior of the cylindrical member is used to rotatably mount the connecting tube;

The elastic member is stretched by the pawl, and the pawl does not prevent the rotation of the notched ratchet. The rotation of the disc drives the spring sheet to shrink and tighten toward a position close to the connecting pipe.

[0016] When the external force for pulling the water spray pipe outward stops, the notched ratchet is reversed under the action of the spring sheet, and the end of the pawl is stuck on the ratchet teeth of the notched ratchet, preventing the notched ratchet from rotating;

[0017] When the water spray pipe is recovered, the water spray pipe is first pulled outward so that the pawl is separated from the ratchet and enters the notch position, the elastic member retracts, and then the water spray pipe is relaxed. Under the action of the spring sheet, the disk is driven to reverse, and the ratchet drives the end of the pawl to change direction. The pawl does not prevent the rotation of the notch ratchet.

[0022] As a preferred solution, the connecting pipe includes a first section and a second section, and the first section and the second section are detachably screwed together;

[0023] A connection joint suitable for connecting to the water outlet of a high-pressure water pump is fixedly provided on the top of the first section;

[0024] The second section is rotatably connected to a water outlet joint, and the water outlet joint is suitable for being connected to the water spray pipe.

[0025] As a preferred solution, the frame includes a mounting portion and a supporting portion, and a handhold portion integrally formed on the mounting portion.

[0026] As a preferred solution, the base plate is fixedly connected to the mounting portion, and driving wheels are fixedly mounted on both sides of the mounting portion.

[0028] The technical solution provided by the utility model has the following advantages:

[0030] When using the integrated high-pressure water jet cleaning machine of the present invention, the water pipe is connected to the water gun and pulled out to a suitable length for water spraying. At this time, the reeling structure is in a power storage state and locks the water pipe so that it cannot be recovered. After use, a section of the water pipe is pulled outward and then released. At this time, the reeling structure releases the elastic force to reel the water pipe back onto the disc. After the reeling is completed, the water pipe is separated from the water gun. In the integrated high-pressure water jet cleaning machine of the present invention, the water pipe reeling device is fixedly installed below the bottom surface of the base plate and is integrated with the water jet cleaning machine, which has a higher degree of equipment integration. When the water pipe needs to be recovered, it is only necessary to pull a section of the water pipe outward and then release it, so that the water pipe can be automatically recovered and wound onto the disc, which can make the cleaning machine simple and convenient to use, save time and effort, and improve efficiency.

[0031] 2. The integrated high-pressure water jet cleaning machine of the present invention has a winding structure including a notched ratchet, a pawl and a spring leaf; the notched ratchet is fixedly arranged on the top outer wall of a cylindrical member located on one side of the disk body and fixedly connected to the disk body, and has two rows of ratchet teeth with a notch between the two rows of ratchet teeth; the interior of the cylindrical member is used for rotatably mounting a connecting pipe; the pawl is rotatably mounted on the bottom surface of the assembly part and is connected to an elastic member fixedly arranged at one end on the bottom surface of the assembly part, and the end of the pawl can be driven by the notched ratchet and the elastic member to change direction; the spring leaf is wrapped around the outside of the connecting pipe, one end of which is fixedly connected to the disk body and the other end is connected to the connecting pipe.

[0032] When the cleaning machine is in use, external force is used to pull the water spray pipe outward, the disc body rotates accordingly and drives the notched ratchet to rotate at the same time. The rotation of the notched ratchet drives the end of the pawl to rotate in the direction of pulling out the water spray pipe. The elastic member is stretched by the pawl, and the pawl does not prevent the rotation of the notched ratchet; the rotation of the disc body drives the spring sheet to shrink and tighten toward a position close to the connecting pipe; when the external force to pull the water spray pipe outward is stopped, the notched ratchet is reversed under the action of the spring sheet, and the end of the pawl is stuck on the ratchet teeth of the notched ratchet, preventing the notched ratchet from rotating; when the water spray pipe is recovered, the water spray pipe is first pulled outward, so that the pawl is separated from the ratchet teeth and enters the notched position, the elastic member retracts, and then the water spray pipe is relaxed. Under the action of the spring sheet, the disc body is reversed, and the ratchet drives the end of the pawl to change direction. The pawl does not prevent the rotation of the notched ratchet, and the water spray pipe is recovered and wound onto the disc body.

[0045] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0046] This embodiment provides an integrated high-pressure water jet cleaning machine, such as Figure 1-2 As shown, it includes: a high-pressure pump 1, an engine 2, a fuel tank 3, a water pipe retracting device 4, a water gun 5 and a frame 6; wherein the frame 6 has a bottom plate 61, the high-pressure pump 1, the engine 2 and the fuel tank 3 are fixedly mounted above the bottom plate 61, the water pipe retracting device 4 is fixedly mounted below the bottom surface of the bottom plate 61, and the water gun 5 is pluggable and arranged on the frame 6; the water pipe retracting device 4 includes an assembly part 44 for fixed connection with the bottom plate 61, a connecting pipe 42 fixedly arranged on the assembly part 44, and a rotatable sleeve mounted on the outside of the connecting pipe 42 suitable for retracting The disc 41 surrounds the water spray pipe 48; the water inlet end of the connecting pipe 42 is connected to the water outlet end of the high-pressure pump 1 through a water pipe, and the water spray pipe 48 connected to the water outlet end of the connecting pipe 42 is connected to the water inlet end of the water spray gun 5; it also includes a reeling structure, which is arranged on the water spray pipe reeling device 4, and stores force when the water spray pipe 48 is pulled outward to be released from the disc 41, and can lock the water spray pipe 48 when the water spray pipe 48 is loosened back, and can release the elastic force to reel the water spray pipe 48 back onto the disc 41 when the water spray pipe 48 is pulled again and loosened back.

[0047] When using the integrated high-pressure water jet cleaning machine of this embodiment, the water pipe 48 is connected to the water gun 5 and pulled outward to an appropriate length for water spraying. At this time, the retraction structure is in a charged state and locks the water pipe 48, preventing it from being retracted. When use is completed, a section of the water pipe 48 is pulled outward and then released. At this time, the retraction structure releases the elastic force and retracts the water pipe 48 onto the disc 41. After retraction is completed, the water pipe 48 is separated from the water gun 5. In the integrated high-pressure water jet cleaning machine of this embodiment, the water pipe retraction device 4 is fixedly mounted below the bottom surface of the base plate 61 and is integrated with the water jet cleaning machine, which has a higher degree of equipment integration. When the water pipe 48 needs to be retracted, it only needs to be pulled outward for a section of the water pipe 48 and then released. The water pipe 48 can be automatically retracted and reeled onto the disc 41, making the cleaning machine simple and convenient to use, saving time and effort, and improving efficiency.

[0048] Specifically, such as Figure 3-6As shown, the retraction structure includes: a notched ratchet 43, a pawl 45 and a spring piece 46; wherein the notched ratchet 43 is fixedly arranged on the top outer wall of a cylindrical member 411 located on one side of the disc body 41 and fixedly connected to the disc body 41, and has two rows of ratchet teeth 430, and a notch is provided between the two rows of ratchet teeth 430; the interior of the cylindrical member 411 is used to rotatably mount the connecting pipe 42; the pawl 45 is rotatably mounted on the bottom surface of the assembly part 44 and is connected to an elastic member 47 fixedly arranged on the bottom surface of the assembly part 44 at one end, and the end of the pawl 45 can be driven by the notched ratchet 43 and the elastic member 47 to change direction; the spring piece 46 is wrapped around the outside of the connecting pipe 42, one end of which is fixedly connected to the disc body 41 and the other end is connected to the connecting pipe 42; when the water spray pipe 48 is pulled outward by external force, the disc body 41 rotates accordingly and simultaneously drives the notched ratchet 43 to rotate, and the rotation of the notched ratchet 43 drives the ratchet The end of the pawl 45 rotates to the direction in which the water spray pipe 48 is pulled out, and the elastic member 47 is stretched by the pawl 45, and the pawl 45 does not prevent the rotation of the notched ratchet 43; the rotation of the disc 41 drives the spring sheet 46 to shrink and tighten toward the position close to the connecting pipe 42; when the external force to pull the water spray pipe 48 outward stops, the notched ratchet 43 is reversed under the action of the spring sheet 46, and the end of the pawl 45 is stuck in the ratchet of the notched ratchet 43 The tooth 430 prevents the notched ratchet 43 from rotating; when the water spray pipe 48 is recovered, the water spray pipe 48 is first pulled outward so that the pawl 45 is separated from the ratchet 430 and enters the notched position, the elastic member 47 retracts, and then the water spray pipe 48 is relaxed. Under the action of the spring sheet 46, the disc 41 is driven to reverse, and the ratchet 430 drives the end of the pawl 45 to change direction. The pawl 45 does not prevent the rotation of the notched ratchet 43.

The rotation of the notched ratchet 6 drives the end of the pawl 9 to rotate in the direction in which the water spray pipe 48 is pulled out, and the elastic member 8 is stretched by the pawl 9, and the pawl 9 does not prevent the rotation of the notched ratchet 6; the rotation of the disc body 1 drives the spring sheet 4 to shrink and tighten toward the position close to the connecting pipe 5; when the external force to pull out the water spray pipe 48 is stopped, the notched ratchet 6 is reversed under the action of the spring sheet 4 When the water pipe 48 is recovered, the end of the pawl 9 is stuck on the ratchet 61 of the notched ratchet 6, preventing the notched ratchet 6 from rotating. When the water pipe 48 is recovered, the water pipe 48 is first pulled outward to separate the pawl 9 from the ratchet 61 and enter the notched position. The elastic member 8 retracts, and then the water pipe 48 is relaxed. Under the action of the spring sheet 4, the disc 1 is driven to reverse, and the ratchet 61 drives the end of the pawl 9 to change direction.

The second disk body 420 has an inner cavity, and an opening 412 is provided on the side wall for winding the water spray pipe 48. The spring sheet 46 is arranged inside the inner cavity; when the water spray pipe 48 is pulled out, the spring sheet 46 is released, and when the water spray pipe 48 is retracted, the spring sheet 46 retracts the water spray pipe 48.
