Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves with filters, and more specifically to a one-way valve with filters installed on a vehicle body high-pressure cleaning machine. Background Art

[0002] A high-pressure car cleaning machine is a device specially used to clean the exterior of a car. It uses high-pressure water flow and nozzles to spray water at high pressure onto the surface of the car body, which can effectively remove dirt, sand, dust and other pollutants on the car body and restore the car body to a clean state. A high-pressure car cleaning machine is usually equipped with nozzles with different pressures and spray modes, and the intensity and angle of the water flow can be adjusted as needed to achieve the best cleaning effect. It is a convenient, fast, efficient and energy-saving car cleaning equipment, widely used in auto repair shops, car washes, gas stations and other places.

[0003] The main problems of the high-pressure cleaning machines currently in use are as follows: First, the high-pressure cleaning machine needs to be shut down and started at any time during use. Each time it is restarted after being shut down, if the intermediate stop time is too long, the water in the pipeline will not maintain pressure and will flow back into the pool, causing air to enter the pipeline. Water needs to be added to the pipeline to expel the air before the water can be pumped out, which greatly reduces the working efficiency of the high-pressure cleaning machine. Second, the current high-pressure cleaning machine has no filter device, which causes the high-pressure cleaning machine to suck some large debris into the high-pressure cleaning machine when pumping water, causing the cleaning machine to get stuck, damage the pump head and other malfunctions, and increase maintenance costs. For this purpose, a one-way valve with a filter is provided for a vehicle body high-pressure cleaning machine. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a vehicle body high-pressure cleaning machine equipped with a one-way valve with a filter, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The utility model is implemented in this way. The utility model provides the following technical solutions: a one-way valve with a filter screen is installed on a high-pressure cleaning machine, including a guide cylinder for support, and a guide filter assembly is arranged on the guide cylinder;

[0006] The flow guide filter assembly includes a blocking block arranged in the flow guide cylinder for isolation, and a plurality of diverter plates for flow guidance are distributed on the outside of the blocking block and along the circumference of the axis point of the blocking block;

[0007] A plurality of the diverter plates are provided with a slot on one side, and a connection ring for limiting is provided at one end of the guide tube;

[0008] The bottoms of the plurality of slots are each provided with a blocking block for blocking, and the side surfaces of each blocking block are each provided with an arc blocking member for blocking;

[0009] It can be seen that in the above technical solution, the blocking block can pull the blocking block and the resisting block to reset through the elasticity of the spring itself, so that the resisting block can be stuck in the dislocation opening, and the outer side of the blocking block can be stuck on the side of the arc stopper, thereby realizing the function of blocking the guide tube, achieving the function of maintaining pressure and preventing air from entering the pipeline, and improving the convenience of the device when in use;

[0010] Optionally, in a possible implementation, the plurality of arc blocks are distributed on the inner wall of the guide tube along the circumference of the axis point of the guide tube, and an offset opening is formed between each two adjacent arc blocks, the offset opening matches the stop block, a sealing gasket is sleeved on the outer side of the stop block, a spring is arranged on the top of the plurality of stop blocks, and the top of each spring extends to the bottom of the connecting ring, an extension tube for support is arranged at one end of the connecting ring, a filter element for filtering is arranged in the extension tube, the vertical cross-section shape of the blocking block is set to be conical, the diverter plate is detachably connected to the blocking block, and a joint is arranged at the end of the guide tube away from the connecting ring;

[0011] It can be seen that in the above technical solution, the guide tube is supported by the joint to ensure the stability of the installation of the guide tube. When the water flows into the guide tube, it is first filtered by the filter element to prevent impurities in the pool from being extracted into the guide tube, and it is also convenient to disassemble and maintain it. The blocking block is displaced due to the impact of the water flow and the spring is stretched. When the blocking block is displaced, it will drive the diverter plate and the resist block to move, so that the resist block can be detached from the offset port, and then the water flow on the outside of the blocking block can be discharged through the offset port and the outside of the blocking block through the joint.

[0012] Technical effects and advantages of the utility model:

[0013] By setting up the diversion and filtering assembly, compared with the prior art, through the corresponding coordinated use of various structures, the blocking block is displaced due to the impact of the water flow and the spring is stretched, so that the block can be separated from the dislocation opening, and then the water flow outside the blocking block can be discharged through the dislocation opening and the outside of the blocking block through the joint;

[0014] The blocking block can be pulled back to its original position by the elasticity of the spring, so that the blocking block can be inserted into the dislocation opening, and the outer side of the blocking block can be stuck on the side of the arc stopper, thereby achieving the function of blocking the guide tube, maintaining pressure and preventing air from entering the pipeline, and improving the convenience of the device when in use;

[0015] When the water flows into the guide tube, it is first filtered by the filter element to prevent impurities in the pool from being drawn into the guide tube. It is also convenient for disassembly and maintenance, thereby improving the convenience of the device during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1-5The vehicle body high-pressure cleaning machine shown is equipped with a one-way valve with a filter screen. Through the diversion and filtering assembly arranged on the guide tube 1, the blocking block 2 is displaced due to the impact of the water flow and the spring 7 is stretched, so that the stop block 6 can be separated from the offset port 9, and then the water flow outside the blocking block 2 can be discharged through the offset port 9 and the outside of the blocking block 2 through the joint 10. The blocking block 2 can pull the blocking block 2 and the stop block 6 to reset through the elasticity of the spring 7 itself, so that the stop block 6 can be stuck in the offset port 9, and the outside of the blocking block 2 can be stuck on the side of the arc stopper 8, thereby realizing the function of blocking the guide tube 1, achieving the function of maintaining pressure and preventing air from entering the pipeline, and improving the convenience of the device when in use. The specific structure of the assembly is arranged as follows;

[0025] The flow guide and filtration assembly includes a blocking block 2 for blocking arranged in a flow guide tube 1, and a plurality of diverter plates 3 for flow guide are distributed on the outside of the blocking block 2 and along the circumference of the axis point of the blocking block 2;

[0026] A plurality of diverter plates 3 are provided with a slot 4 on one side, and a connection ring 5 for limiting is provided at one end of the guide tube 1;

[0027] The bottom of the plurality of slots 4 is provided with a blocking block 6 for blocking, and the side of each blocking block 6 is provided with an arc blocking member 8 for blocking;

[0028] A plurality of arc stops 8 are distributed on the inner wall of the guide tube 1 along the circumference of the axis point of the guide tube 1, and an offset opening 9 is formed between each adjacent two arc stops 8, the offset opening 9 matches the stop block 6, a sealing gasket is sleeved on the outer side of the stop block 6, a spring 7 is arranged on the top of the plurality of stop blocks 6, and the top of each spring 7 extends to the bottom of the connecting ring 5, an extension tube 11 for support is arranged at one end of the connecting ring 5, a filter element 12 for filtering is arranged in the extension tube 11, the vertical cross-section shape of the blocking block 2 is arranged to be conical, the diverter plate 3 is detachably connected to the blocking block 2, and a joint 10 is arranged at the end of the guide tube 1 away from the connecting ring 5.

[0029] According to the above structure, when in use, the staff installs the device at the water inlet of the cleaning machine. During installation, the guide tube 1 is supported by the joint 10 to ensure the stability of the installation of the guide tube 1. When the water flows into the guide tube 1, it is first filtered by the filter element 12 to prevent impurities in the pool from being extracted into the guide tube 1, and it is also convenient to disassemble and maintain it.

[0030] And when the filtered water flow will first contact the blocking block 2, the blocking block 2 will be displaced due to the impact of the water flow and the spring 7 will be stretched.
