Description

Technical Field

[0001] This utility model relates to the technical field of nozzle adjustment equipment, specifically a nozzle adjustment device. Background Technology

[0002] Nozzles are important components in spraying equipment. To facilitate the control of the spraying speed, nozzle adjustment devices are often required. Utility model patent application CN201820320707.4 discloses a flow-adjustable nozzle. When the nozzle flow rate is high, the number of contacts between the inlet pipe and the drainage channel is small, resulting in low drainage capacity. When the nozzle flow rate needs to be reduced, rotating the adjusting sleeve connects the inlet pipe to more drainage channels, increasing the drainage capacity. The drainage capacity can be adjusted to meet different flow requirements. The drainage channels are used to depressurize the water, thereby reducing the pressure inside the roller and preventing excessive pressure inside the nozzle while reducing the spray flow rate. According to the disclosed technical solution, existing nozzle adjustment devices, on the one hand, cannot effectively improve the atomization effect of the liquid, and are prone to incomplete atomization due to liquid flowing along the inner wall of the nozzle, which is detrimental to improving the uniformity of the spray. On the other hand, during spraying, insufficient pressure can easily lead to poor atomization, thus compromising spray quality.

[0003] Therefore, how to design a nozzle adjustment device has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nozzle adjustment device to solve the problems mentioned in the background art. This utility model is reasonably designed, convenient to use, and suitable for adjusting the spray of nozzles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nozzle adjustment device, comprising a nozzle and a support, wherein an inlet assembly is installed on the nozzle, the inlet assembly comprising an air pipe and a liquid pipe, an atomizing assembly is installed at the bottom of the nozzle, the atomizing assembly comprising a cone block and a support rod, a homogenizing assembly is installed on the liquid pipe, the homogenizing assembly comprising a guide ring and a port, an adjustment assembly is installed on the air pipe, the adjustment assembly comprising a valve and a first gear, a drive assembly is installed on the outer side of the air pipe, the drive assembly comprising a motor and a second gear, and a control assembly is installed on the support, the control assembly comprising a piston and a button.

[0006] Furthermore, the support is welded to the top of the nozzle, the air pipe is welded to the top of the support, the liquid pipe is welded to one side of the nozzle, and the bottom of the air pipe passes through the support and is connected to the nozzle.

[0007] Furthermore, the cone block is welded to the inner wall of the bottom of the nozzle by a support rod, one end of the liquid tube passes through the nozzle and extends to the inner side of the nozzle, the guide ring is welded to one end of the liquid tube, the port is opened on the inner side of the guide ring, the ports are evenly distributed on the guide ring, and the liquid tube is connected to the inner side of the nozzle through the guide ring and the port.

[0008] Furthermore, an electric valve is installed on the liquid pipe, a support is welded to the other side of the gas pipe, and the valve is installed inside the gas pipe.

[0009] Furthermore, one end of the valve passes through the inner wall of the air pipe and extends to the inner side of the support sleeve, the gear is installed on the outer side of one end of the valve, and the motor is installed on the outer side of the support sleeve by bolts.

[0010] Furthermore, the second gear is installed inside the support sleeve, one side of the second gear passes through the inner wall of the support sleeve and is keyed to the output shaft of the motor, and the second gear meshes with the first gear.

[0011] Furthermore, the support has an inner cavity on its inner side, which is connected to the nozzle. The piston is locked on the inner wall of one end of the inner cavity, and the piston is connected to the inner wall of the other end of the inner cavity by a spring.

[0012] Furthermore, the button is bolted to the inner wall at the other end of the cavity, and the button is connected to the electric valve via a wire.

[0013] Beneficial effects: 1. When using this nozzle adjustment device, high-pressure airflow is introduced into the inner side of the nozzle through the air pipe, and then liquid is introduced through the liquid pipe. The liquid then flows out evenly to the center of the nozzle through the inlet in the guide ring. The high-speed airflow blows the liquid and generates airflow on the outer side of the guide ring, preventing the liquid from adhering to the inner wall of the nozzle and avoiding insufficient atomization due to the liquid flowing along the inner wall of the nozzle. At the same time, the high-speed airflow atomizes the liquid, and the water droplets hit the cone block for further atomization, thereby effectively improving the atomization effect of the liquid.

[0014] 2. When in use, the motor drives gear two to rotate on the outside of the support. Gear two, through meshing with gear one, drives the valve to rotate on the inside of the air pipe, thereby adjusting the air pressure entering the nozzle through the air pipe. Only when the air pressure inside the nozzle is sufficient, the air pressure pushes the piston, the piston compresses the spring and squeezes the button, thereby opening the electric valve and allowing liquid to enter the inside of the nozzle through the liquid pipe. The electric valve adjusts the liquid flow rate, and the motor adjusts the valve to regulate the airflow speed. This allows for adjustment of the nozzle's spray effect as needed and avoids unsatisfactory atomization due to insufficient air pressure, ensuring the quality of the nozzle's spray.

[0015] 3. This nozzle adjustment device is reasonably designed, highly efficient and convenient to use, and suitable for adjusting the spray pattern of the nozzle. Attached Figure Description

[0021] Please see Figures 1 to 3This utility model provides a technical solution: a nozzle adjustment device, including a nozzle 1 and a support 2. An inlet assembly is installed on the nozzle 1, the inlet assembly including an air pipe 3 and a liquid pipe 4.

A drive assembly is installed on the outer side of the air pipe 3, the drive assembly including a motor 13 and a gear 14. A control assembly is installed on the support 2, the control assembly including a piston 15 and a button 17. The support 2 is welded to the top of the nozzle 1, the air pipe 3 is welded to the top of the support 2, the liquid pipe 4 is welded to one side of the nozzle 1, and the bottom of the air pipe 3 passes through the support 2 and is connected to the nozzle 1. The cone 5 is welded to the inner wall of the bottom of the nozzle 1 via a support rod 6. One end of the liquid pipe 4 passes through the nozzle 1 and extends to the inner side of the nozzle 1. The guide ring 7 is welded to one end of the liquid pipe 4. The port 8 is opened on the inner side of the guide ring 7 and is evenly distributed on the guide ring 7. The liquid pipe 4 is connected to the inner side of the nozzle 1 through the guide ring 7 and the port 8. In use, high-pressure airflow is introduced into the inner side of the nozzle 1 through the air pipe 3, and then liquid is introduced through the liquid pipe 4. Then, it flows evenly out to the center of the nozzle 1 through the port 8 in the guide ring 7. The high-speed airflow blows the liquid and generates airflow on the outside of the guide ring 7, preventing the liquid from adhering to the inner wall of the nozzle 1 and avoiding insufficient atomization due to the liquid flowing along the inner wall of the nozzle 1. At the same time, the high-speed airflow atomizes the liquid, and the water droplets hit the cone 5 for further atomization, thereby effectively improving the atomization effect of the liquid.

[0022] In this embodiment, an electric valve 9 is installed on the liquid pipe 4, a support sleeve 11 is welded to the other side of the air pipe 3, a valve 10 is installed inside the air pipe 3, one end of the valve 10 passes through the inner wall of the air pipe 3 and extends to the inner side of the support sleeve 11, a gear 12 is installed on the outer side of one end of the valve 10, a motor 13 is installed on the outer side of the support sleeve 11 by bolts, a gear 2 14 is installed inside the support sleeve 11, one side of the gear 2 14 passes through the inner wall of the support sleeve 11 and is keyed to the output shaft of the motor 13, the gear 2 14 meshes with the gear 12, an inner cavity is opened on the inner side of the support 2, the inner cavity is connected to the nozzle 1, a piston 15 is stuck on the inner wall of one end of the inner cavity, the piston 15 is connected to the inner wall of the other end of the inner cavity by a spring 16, and a button 17 is installed by bolts. On the inner wall of the other end of the inner cavity, the button 17 is connected to the electric valve 9 via a wire. In use, the motor 13 drives the gear 14 to rotate on the outside of the support 11. The gear 14, through meshing with the gear 12, drives the valve 10 to rotate on the inside of the air pipe 3, thereby adjusting the air pressure entering the nozzle 1 through the air pipe 3. Only when the air pressure in the nozzle 1 is sufficient, the air pressure pushes the piston 15, the piston 15 compresses the spring 16 and squeezes the button 17, thereby opening the electric valve 9, allowing liquid to enter the inside of the nozzle 1 through the liquid pipe 4. The electric valve 9 adjusts the liquid flow rate, and the motor 13 adjusts the valve 10 to adjust the airflow rate, thereby adjusting the spray effect of the nozzle 1 as needed and avoiding unsatisfactory atomization effect of the liquid entering the nozzle 1 due to insufficient air pressure, thus ensuring the spray quality of the nozzle 1.

[0023] The nozzle adjustment device provides power to all electrical equipment via an external power supply. During use, high-pressure airflow is introduced into the inner side of nozzle 1 through air pipe 3, and liquid is introduced through liquid pipe 4. The liquid then flows evenly outwards from the center of nozzle 1 through the opening 8 inside guide ring 7. The high-speed airflow agitates the liquid and generates airflow on the outer side of guide ring 7, preventing liquid from adhering to the inner wall of nozzle 1 and avoiding insufficient atomization due to liquid flowing along the inner wall. Simultaneously, the high-speed airflow atomizes the liquid, and water droplets impact the cone block 5 for further atomization, effectively improving the atomization effect. Motor 13 drives gear 14 to rotate on the outer side of support sleeve 11. Wheel 2 14, through meshing with gear 12, drives valve 10 to rotate inside air pipe 3, thereby regulating the air pressure entering nozzle 1 through air pipe 3. Only when the air pressure inside nozzle 1 is sufficient, the air pressure pushes piston 15, piston 15 compresses spring 16 and squeezes button 17, thereby opening electric valve 9, allowing liquid to enter the inside of nozzle 1 through liquid pipe 4. The liquid flow rate is regulated by electric valve 9, and valve 10 is regulated by motor 13 to regulate airflow speed. This allows for adjustment of the spray effect of nozzle 1 as needed, and avoids unsatisfactory atomization effect caused by insufficient air pressure, ensuring the spray quality of nozzle 1.
