Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, specifically to a dual-water-path pressure relief and labor-saving spray gun. Background Technology

[0002] The dual-fluid-channel pressure relief spray gun is a high-performance spray gun that integrates dual fluid channels, automatic pressure relief function and low operating force characteristics. It solves the safety hazards and laborious operation problems of traditional spray guns, and also improves the overall stability and service life of the system. It has broad application prospects and market value, and is used in high-pressure cleaning applications.

[0003] However, spray guns often only support a single spraying mode, making it difficult to flexibly adjust the spray pattern or flow rate according to actual needs. At the same time, the cleaning fluid and the main water circuit are usually not effectively separated, affecting the mixing efficiency and spray uniformity. In addition, when the spray gun is connected to the water supply pipeline, it often uses threaded or snap-fit ​​methods, which are cumbersome to disassemble and assemble, and lack a filter structure, making it easy for impurities to enter and cause nozzle blockage or internal component wear.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a dual-water-path pressure relief and labor-saving spray gun to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A dual-water-path pressure-relief spray gun includes a pressure-relief spray gun and an adjustment assembly connected to the upper part of the pressure-relief spray gun. The adjustment assembly includes a pressure-relief nozzle at one end of the pressure-relief spray gun, an adjustment cylinder at one end of the pressure-relief nozzle, an adjustment rod inside the adjustment cylinder, a blocking block on the surface of the adjustment rod, one side of the blocking block contacting the inside of the adjustment cylinder, and multiple spray pipes outside the adjustment cylinder. One of the spray pipes has a spray bottle seat on its surface, and the spray bottle seat and one end of another spray pipe are provided with an adjustment spray nozzle. An auxiliary assembly is connected to one end of the pressure-relief spray gun.

[0008] Furthermore, in order to better facilitate quick connection of the spray gun delivery pipe and auxiliary filtration, the auxiliary components include a quick connector 1 at one end of the pressure relief spray gun, a filter cylinder 1 at one end of the quick connector 1, a filter cylinder 2 inside the filter cylinder 1, a filter element inside the filter cylinder 2, a quick connector 2 on one side of the filter cylinder 2, and a delivery pipe at one end of the quick connector 2.

[0009] Furthermore, in order to better assist in pressurization, a pressure rod is provided on the spray bottle holder, and a pressure handle is provided at one end of the pressure rod.

[0010] Furthermore, in order to better improve the sealing performance at the junction of the adjusting rod and the adjusting cylinder, multiple sealing rings are placed on the surface of the adjusting rod, and the sealing rings are set at the junction of the adjusting cylinder and the adjusting rod.

[0011] Furthermore, in order to better assist in limiting the adjusting rod, multiple limiting holes are opened at relatively opposite positions inside the pressure relief spray gun. An elastic plunger is installed inside the limiting hole, and one end of the elastic plunger is in contact with the surface of the adjusting rod.

[0012] Furthermore, a spray bottle is connected inside the spray bottle holder, and a suction tube is installed inside the spray bottle, which is connected to the spray pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The adjustment components installed on the pressure relief spray gun can not only achieve flexible adjustment of spray pattern and flow rate to meet the needs of different cleaning tasks, but also achieve independent delivery and spraying of cleaning fluid, ensuring separation of cleaning fluid from the main water circuit, thereby improving mixing efficiency and spray uniformity. The auxiliary components installed on the pressure relief spray gun can not only achieve quick connection and disassembly of the spray gun and water supply pipeline, avoiding the cumbersome operation of traditional thread or snap-fit ​​methods and improving work efficiency, but also effectively filter impurities, prevent nozzle blockage and internal component wear, extend the service life of the spray gun, and improve the cleaning effect and equipment reliability.

[0015] (2) The pressure rod and pressure handle set in the spray bottle seat make it easier to control the spraying of cleaning fluid, especially in work scenarios where frequent start-up or stop spraying is required, which greatly improves the convenience of operation. The elastic plunger set in the limiting hole can provide a stable reaction force, which helps to maintain the stability of the position of the adjusting rod, prevents the adjustment rod from being displaced due to external force or vibration, and makes the pressure adjustment more precise, ensuring that the spray gun can maintain a stable spraying effect under different working conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] like Figures 1-2 , Figure 4 As shown, a dual-water-path pressure relief spray gun according to an embodiment of the present invention includes a pressure relief spray gun 1, an adjustment assembly 2 connected to the upper part of the pressure relief spray gun 1, the adjustment assembly 2 including a pressure relief spray pipe 201 at one end of the pressure relief spray gun 1, an adjustment cylinder 202 at one end of the pressure relief spray pipe 201, an adjustment rod 203 inside the adjustment cylinder 202, a blocking block 204 on the surface of the adjustment rod 203, one side of the blocking block 204 contacting the inside of the adjustment cylinder 202, and two spray pipes 205 outside the adjustment cylinder 202, one of the spray pipes 205 having a spray bottle seat 206 on its surface, and an adjustment spray nozzle 207 at one end of the spray bottle seat 206 and the other spray pipe 205.

[0026] A pressure rod 4 is provided on the spray bottle holder 206. A pressure handle 5 is provided at one end of the pressure rod 4. Two sealing rings 6 are in contact with the surface of the adjusting rod 203. The sealing rings 6 are located at the junction of the adjusting cylinder 202 and the adjusting rod 203.

[0027] The pressure relief spray gun 1 has four limiting holes with relative positions inside. The limiting holes are equipped with elastic plungers 7 to limit the adjusting rod 203. One end of the elastic plunger 7 is in contact with the surface of the adjusting rod 203. The spray bottle seat 206 is connected to a spray bottle 8 for storing cleaning fluid. The spray bottle 8 is equipped with a suction tube 9 for assisting in conveying the stored cleaning fluid. The suction tube 9 is connected to the spray pipe 205.

[0028] Example 2:

[0029] like Figure 1 , Figure 3 As shown, according to an embodiment of the present invention, a dual-water-path pressure relief and labor-saving spray gun is provided. An auxiliary component 3 is connected to one end of the pressure relief spray gun 1. The auxiliary component 3 includes a quick connector 301 at one end of the pressure relief spray gun 1, a filter cylinder 302 at one end of the quick connector 301, a filter cylinder 303 inside the filter cylinder 302, the filter cylinder 303 being threadedly connected to the inside of the filter cylinder 302, a filter element 304 inside the filter cylinder 303, the filter element 304 may also be other filter materials, a quick connector 305 on one side of the filter cylinder 303, and a delivery pipe 306 at one end of the quick connector 305.

[0030] The quick connector 2 (305), filter element 304, quick connector 1 (301), spray bottle 8, elastic plunger 7, sealing ring 6, pressure rod 4, and adjusting spray nozzle 207 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, during use, water flows through the delivery pipe 306 and is introduced into the filter cartridge 303 via the quick connector 305. The filter element 304 filters impurities in the water, ensuring that the water entering the pressure relief spray gun 1 is clean and preventing clogging of the spraying system. The filtered water then flows sequentially through the filter cartridge 302 and the quick connector 301 into the pressure relief spray gun 1.

[0033] The pressure relief spray gun 1 has a dual water path structure. One path is used for the main spray water flow, and the other path is connected to the suction pipe 9 in the spray bottle 8. The cleaning liquid in the spray bottle 8 is sucked into the spray pipe 205 through the Venturi effect or pressure difference. The spray bottle 8 is installed in the spray bottle seat 206. The suction pipe 9 is connected to the spray pipe 205 to achieve the mixing of the cleaning liquid and the main water flow. When the operator pushes the adjusting rod 203, the blocking block 204 on the surface of the adjusting rod 203 moves inside the adjusting cylinder 202, changing the opening and closing state of the water flow channel, thereby switching the spray pattern or activating the pressure relief mechanism. A sealing ring 6 is provided at the junction of the adjusting rod 203 and the adjusting cylinder 202 to ensure that the water flow does not leak from the adjusting gap and maintain the stability of the system pressure.

[0034] During the movement of the adjusting rod 203, the elastic plunger 7 in the limiting hole inside the pressure relief spray gun 1 contacts the surface of the adjusting rod 203, providing positioning feedback and limiting function, so that the adjusting rod 203 can stay stably in multiple preset positions, achieving precise gear control. At the same time, the spray bottle holder 206 is equipped with a pressure rod 4 and a pressure handle 5. The operator can manually press the pressure handle 5 to drive the pressure rod 4, applying additional pressure to the inside of the spray bottle 8, improving the suction efficiency of the cleaning fluid and the uniformity of spray mixing, which is especially suitable for high viscosity liquids or long-distance spraying scenarios. The mixed liquid is sprayed out through the adjusting spray nozzle 207.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
