Description

Technical Field

[0001] This utility model belongs to the field of car wash equipment technology, specifically relating to an automatic angle high-pressure water spray mechanism. Background Technology

[0002] The high-pressure water spray mechanism is the core component for achieving efficient cleaning. It mainly consists of a high-pressure pump, water spray pipeline, nozzles, and control components. Its working principle is that the high-pressure pump is driven by a motor to pressurize ordinary tap water to 5-15MPa (some industrial-grade systems can reach even higher). The high-pressure water flow is delivered to the nozzle through a high-pressure resistant pipeline. Through the flow-limiting and guiding design of the nozzle, the water flow is transformed into a high-speed jet. The nozzles usually adopt a fan-shaped or columnar spray pattern. The fan-shaped jet has a wide coverage area and is suitable for washing large areas of floating dust on the car body. The columnar jet has a strong impact force and can remove stubborn stains. Some mechanisms are also equipped with adjustable nozzles or rotating spray heads to adapt to different cleaning scenarios. The control components are responsible for adjusting the water pressure, water flow direction, and spray duration to ensure cleaning effect while avoiding damage to the car paint. It is widely used in self-service car wash machines, fully automatic car wash lines, and other equipment.

[0003] The utility model patent application number "CN221477040U" entitled "A Car Wash Machine Spray Device" mentions that "the car wash machine spray device discloses that, through the setting of a translation mechanism, after connecting to an external power source to power the servo motor, it drives the screw screw to rotate, causing the spray frame to translate on the top surface of the track, thereby achieving the effect of spraying and rinsing different parts of the vehicle. Through the setting of a drying mechanism, after rinsing, after connecting to an external power source to power the electric heating grid, the electric heating grid heats up, and the fan turns on to blow hot air onto the surface of the vehicle, thereby achieving the effect of quickly drying the water stains remaining after washing the car." However, this car wash machine spray device does not have a quick-installation structure for the spray nozzles, making it inconvenient to repair or replace them after long-term use. Furthermore, it does not have a spray nozzle angle adjustment structure, making it difficult to cope with different working conditions. It has low adaptability and poor practicality, making it difficult to promote its use.

[0004] Therefore, there is an urgent need for an automatic angle high-pressure water spray mechanism to solve the current problem that the water source entering the double-suction pump contains various impurities. After entering the pump body, these impurities easily adhere to the surface of the impeller and pump casing components, affecting the pump flow rate, reducing the pump's working efficiency, causing wear on impeller, pump casing and other components, and shortening the pump's service life. Summary of the Invention

[0005] In view of this, this utility model proposes an automatic angle high-pressure water spray mechanism, which is applied to the field of car wash equipment processing technology. It solves the existing technical problems that the water source entering the double suction pump contains various impurities, which easily adhere to the surface of the impeller and pump casing after entering the pump body, affecting the pump flow rate, reducing the pump working efficiency, causing wear on impeller, pump casing and other components, and shortening the service life of the pump.

[0006] To achieve the above-mentioned technical objectives, the specific technical solution adopted by this utility model is as follows: An automatic angle high-pressure water spray mechanism includes a mounting frame, a first fixed base, and a second fixed base.

[0007] Furthermore, the angle adjustment assembly includes a motor, a first bevel gear, a gearbox, a second bevel gear, a guide rod, and a guide groove. The first bevel gear is fixedly installed at the output end of the motor. The gearbox is fixedly installed on the side of the mounting bracket near the first fixed seat. The second bevel gear is fixedly installed at the end of the water pipe near the first bevel gear, and a guide groove is fixedly installed at the end of the water pipe away from the second bevel gear. The outer wall of the second fixed seat has a guide groove. The first bevel gear and the second bevel gear are meshed, and the guide rod and the guide groove are slidably connected, thereby achieving the adjustment of the spray angle of the nozzle through the angle adjustment assembly.

[0008] Furthermore, both the first and second bevel gears are located inside the gearbox to prevent dust, moisture, corrosive liquids, and other impurities from entering the surface of the transmission components and to prevent impurities from adhering to their tooth surfaces.

[0009] Furthermore, the positioning block and positioning groove are plug-in installed, the nozzle and connector are compatible, and the limiting plate and limiting groove are compatible.

[0021] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0022] In one embodiment of this utility model, such as Figures 1 to 7 As shown, an automatic angle high-pressure water spray mechanism is mentioned, including a mounting frame 1, a first fixed seat 2, and a second fixed seat 3. A water pipe 4 is rotatably installed between the first fixed seat 2 and the second fixed seat 3. An angle adjustment component 5 is provided on the outer wall of the water pipe 4. A connector 6 is fixedly installed on the outer wall of the water pipe 4. A nozzle 7 is provided at the end of the connector 6 away from the water pipe 4. A limit plate 8 and a positioning block 9 are fixedly installed at the end of the nozzle 7 near the connector 6. An installation groove 11 is opened at the end of the nozzle 7 near the connector 6. A positioning groove 10 is opened at the end of the connector 6 near the nozzle 7. A sealing ring 12 is provided on the inner wall of the installation groove 11. An ear seat 13 is fixedly installed on the outer wall of the connector 6. A rotating shaft 14 is rotatably installed on the outer wall of the ear seat 13. A pressure block 15 is fixedly installed on the outer wall of the rotating shaft 14. A torsion spring 16 is provided on the outer wall of the rotating shaft 14. A limit groove 17 is opened at the end of the pressure block 15 away from the rotating shaft 14.

[0023] The angle adjustment assembly 5 includes a motor 501, a first bevel gear 502, a gearbox 503, a second bevel gear 504, a guide rod 505, and a guide groove 506. The first bevel gear 502 is fixedly mounted on the output end of the motor 501. The gearbox 503 is fixedly mounted on the side of the mounting bracket 1 near the first fixed seat 2. The second bevel gear 504 is fixedly mounted on the end of the water pipe 4 near the first bevel gear 502, and a guide groove 506 is fixedly mounted on the end of the water pipe 4 away from the second bevel gear 504. The outer wall of the second fixed seat 3 has a guide groove 506. The first bevel gear 502 and the second bevel gear 504 are meshed, and the guide rod 505 is slidably connected to the guide groove 506. The advantage is that when the operator starts the motor 501, the output end of the motor 501 rotates, which, through the engagement of the first bevel gear 502 and the second bevel gear 504, drives the water pipe 4 to rotate, thereby driving the nozzle 7 to rotate. This allows for adjustment of the spray angle of the nozzle 7, facilitating adaptation to different working conditions and providing high compatibility. Both the first bevel gear 502 and the second bevel gear 504 are located inside the gearbox 503. Through the design of the gearbox 503, it isolates the first bevel gear 502 and the second bevel gear 504 from the external environment, preventing dust, moisture, corrosive liquids, and other impurities from entering the transmission components. This prevents impurities from adhering to their tooth surfaces, reducing wear during meshing and lowering the failure rate. The positioning block 9 and the positioning groove 10 are plug-in installed. The nozzle 7 is compatible with the connector 6, and the limiting plate 8 is compatible with the limiting groove 17. The advantage is that when the operator presses the pressure block 15, inserts the nozzle 7 into the connector 6, and simultaneously inserts the positioning block 9 into the positioning groove 10, and then stops pressing the pressure block 15, the limiting plate 8 is inserted into the limiting groove 17, allowing for quick installation of the nozzle 7. However, after prolonged use, this makes maintenance or replacement inconvenient.

[0024] The sealing ring 12 is made of rubber. There are three identical sealing rings 12, which are evenly spaced. The sealing ring 12 made of rubber has good elasticity and sealing performance, and can fit tightly against the contact surface of the mounting groove 11 and the connector 6, which can prevent water from leaking out from the connection between the nozzle 7 and the connector 6, and has a high sealing performance.

[0025] One end of the torsion spring 16 is fixedly installed to the rotating shaft 14, and the other end is fixedly installed to the connector 6. The advantage is that the design of the torsion spring 16 allows for automatic reset of the pressure block 15, ensuring the reliability of the nozzle 7's fixation, saving time on resetting the stop block, improving installation efficiency, and offering high practicality. Two pressure blocks 15 are provided, symmetrically distributed about the center line of the connector 6, and the overall structure of the pressure blocks 15 is "L". The advantage is that the design of two pressure blocks 15 allows for easy one-handed pressing by the operator, and the two pressure blocks 15 can apply uniform clamping force to the nozzle 7 from both sides of the connector 6, improving stability after installation.

[0026] In the process of using this utility model, the installation work is performed first. The worker presses down on the pressure block 15, then inserts the nozzle 7 into the connector 6, and simultaneously inserts the positioning block 9 into the positioning groove 10. Then, pressing down on the pressure block 15 stops, allowing the limiting plate 8 to insert into the limiting groove 17, achieving quick installation of the nozzle 7 and facilitating its inspection and replacement. The torsion spring 16 enables the pressure block 15 to automatically reset, ensuring the reliable fixation of the nozzle 7, saving time for resetting the stop block, and improving installation efficiency. The two pressure blocks 15 allow the worker to press with one hand, and at the same time, the two pressure blocks 15 can apply a uniform clamping force to the nozzle 7 from both sides of the connector 6, improving the stability after installation. In actual use... First, the operator starts the motor 501. The output of the motor 501 rotates, which drives the water pipe 4 to rotate through the engagement of the first bevel gear 502 and the second bevel gear 504. This, in turn, drives the nozzle 7 to rotate, thus adjusting the spray angle of the nozzle 7. The gearbox 503 isolates the first bevel gear 502 and the second bevel gear 504 from the external environment, preventing dust, water vapor, corrosive liquids and other impurities from entering the transmission components. This also prevents impurities from adhering to the tooth surfaces, reducing wear during meshing and lowering the failure rate. In summary, this invention has the advantages of convenient nozzle angle adjustment, prevention of impurities from entering the transmission components, convenient installation and disassembly, good sealing performance, high connection stability and reduced failure rate.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
