Description

Technical Field

[0001] The utility model relates to the technical field of air-water mixing atomizing nozzles, in particular to an anti-drip air-water mixing atomizing nozzle. Background Art

[0002] The anti-drip gas-water mixing atomizing nozzle is a specially designed nozzle designed to effectively mix and atomize liquid and gas while preventing liquid from dripping. By mixing gas and liquid, fine droplets are produced, increasing the atomization effect and improving coverage. It is more common in daily life.

[0003] Existing technologies include the utility model with announcement number CN209205577U, which discloses an air-water mixing atomizing nozzle. The patent includes a nozzle body, a water flow channel, an air injection channel, an ultrasonic vibration piezoelectric ceramic piece, an atomizing channel, a water outlet chamber and an air flow differentiation device, wherein the water flow channel is arranged at the center position of the nozzle body; the utility model has a reasonable structural design. When the water flows through the atomizing nozzle, it first passes through a section with an air injection channel. The air injection channel injects external air into the water flow channel and mixes it with water, increasing the water flow rate under the same unit water output. The ultrasonic vibration piezoelectric ceramic piece is used to perform preliminary atomization on the water flow, and the water flow is combined with air again through the atomizing channel to enhance the water flow rate and improve the water efficiency and atomization speed. Finally, it is atomized again through the air flow differentiation device. At the same time, the high-speed rotating airflow also increases the spray distance, which is very practical.

[0004] In daily use, it is found that during the operation of the gas-water mixing atomizing nozzle, since the gas-water mixing atomizing nozzle uses internal pressure to squeeze the internal liquid into the nozzle, the high-pressure liquid rotates through the diverter core and then is sprayed out through the liquid outlet to form atomization. At this time, it will be inconvenient to regulate the water flow in the gas-water mixing cavity, which will cause the liquid to accumulate and drip after the nozzle stops working, resulting in moisture in the equipment or the surrounding environment. Utility Model Content

[0012] Preferably, the arc surfaces of the first closing column and the second closing column are both fixedly connected with sealing rings, and the sealing rings are rubber rings.

[0013] The effect achieved by the above component is that when the first through hole and the second through hole formed on the surface of the closing plug are inserted and closed with the first closing column and the second closing column, the sealing ring made of rubber material can increase the sealing performance.

[0014] Preferably, the surface of the communication pipe is fixedly connected with two acrylic plates, and the two acrylic plates are located on the bottom end side wall of the communication pipe.

It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0028] The specific implementation of the present application is described in detail below with reference to specific embodiments.

[0029] Please refer to Figures 1 to 4 The water and air mixed atomizing nozzle provided by the embodiment of the present application comprises a mixed cavity 1 and a water inlet pipe 6, one side of the mixed cavity 1 is fixedly communicated with an air inlet pipe 3, one end of the mixed cavity 1 away from the air inlet pipe 3 is fixedly communicated with a nozzle body 2, the bottom surface of the mixed cavity 1 is fixedly communicated with a butt joint pipe 5, and one end of the butt joint pipe 5 away from the mixed cavity 1 is provided with an opening and closing mechanism 4.

[0030] In the embodiment of the present application, please refer to Figure 2 , Figure 3 and Figure 4The output end is fixedly connected with a closing plug 408, and the closing plug 408 is located on the inner wall of the connecting pipe 401. The surface of the closing plug 408 is slidably connected to the inner wall of the connecting pipe 401. A first through hole 409 and a second through hole 410 are respectively opened on both sides of the surface of the closing plug 408. The bottom end of the inner wall of the connecting pipe 401 is fixedly connected with a first closing column 412 and a second closing column 413 at the positions corresponding to the first through hole 409 and the second through hole 410. The two side surfaces of the servo cylinder 402 are fixedly connected with a rotating frame 406, and the inner wall of the rotating frame 406 is rotatably connected with a rotating plate 405. The cross-section of the bottom end of the rotating plate 405 is "U"-shaped. The arc surface of the connecting pipe 401 is fixedly connected with a fixing ring 415, and the fixing ring 415 is fixedly connected with a fixing column 403 at the position corresponding to the rotating plate 405. The arc of the fixing column 403 The surface is threadedly connected with a fixed shaft 404, and the upper end of the inner wall of the connecting pipe 401 is fixedly connected with a retaining ring 411, which is located below the water inlet pipe 6. The lower surface of the retaining ring 411 abuts against the upper surface of the closing plug 408. The arc surfaces of the first closing column 412 and the second closing column 413 are fixedly connected with a sealing ring 414, which is a rubber ring. Two acrylic plates 407 are fixedly connected to the surface of the connecting pipe 401. The two acrylic plates 407 are located on the bottom end side walls of the connecting pipe 401. The closing plug 408 is a stainless steel plug. The length of the closing plug 408 is adapted to the cross-sectional size of the butt-jointed pipe 5. The first closing column 412 is longer than the second closing column 413. When the closing plug 408 is pressed down and the first through hole 409 is in contact with the first closing column 412, the second through hole 410 is not in contact with the second closing column 413.

[0031] The working principle of the anti-drip air-water mixing atomizing nozzle provided by the present invention is as follows: when operating the air-water mixing atomizing nozzle, the water inlet pipe 6 is connected to the connecting pipe 5 with the help of a closing mechanism, so that the connecting pipe 5 and the mixing chamber 1 are connected, and then the air inlet pipe 3 is used in conjunction with the nozzle body 2 for operation. In order to facilitate the adjustment of the opening of the water inlet pipe 6 in the entire nozzle to prevent dripping caused by excessive water inflow, the servo cylinder 402 is started at this time, and the servo cylinder 402 drives the closing plug 408 at the output end to slide up and down along the inner wall of the connecting pipe 401. When a large amount of water flow needs to be delivered to the mixing chamber 1, the closing plug 408 is moved upward until the upper end of the closing plug 408 abuts against the retaining ring 411. At this time, the water flow will simultaneously pass through the first through-hole The hole 409 and the second through hole 410 flow into the docking pipe 5 and the mixing chamber 1. When a smaller water flow is required, the closing plug 408 is moved toward the position of the first closing column 412. At this time, the first through hole 409 is just in contact with the first closing column 412 and closed, while the second through hole 410 continues to pass the water flow. When the water flow is not needed, the entire closing plug 408 is continued to be moved toward the bottom end of the connecting pipe 401 until the first through hole 409 and the second through hole 410 opened on the surface of the closing plug 408 are completely plugged and closed with the first closing column 412 and the second closing column 413. At the same time, the arc surface of the entire closing plug 408 closes the water inlet of the docking pipe 5. Through the operation of the above situation, the water flow in the entire mixing chamber 1 can be conveniently regulated.
