Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to an adjustable nozzle. Background Technique

[0002] Industrial nozzles, also known as industrial spray heads or nozzles in Chinese, are often simply referred to as nozzles. Most industrial nozzles are installed in various spraying, atomizing, oil spraying, sandblasting, spraying and other equipment, playing different roles, and are widely used in industries such as environmental protection, pretreatment before painting, circuit boards, petroleum, chemical industry, steel, metallurgy, electronics, cement, food, papermaking, printing, agriculture and animal husbandry, and can be said to be everywhere.

[0003] The authorized announcement number CN214917463U discloses an adjustable nozzle. This patented technology is equipped with a nozzle body, a support cylinder, an adjustment handle, a rotating shaft, a push plate, a push rod, a bottom rod, a second bevel gear and other structures. When the adjustment handle rotates clockwise, through the meshing transmission of bevel gears, the control screw rotates forward, thereby pushing the nozzle body upward. When the adjustment handle rotates counterclockwise, the height of the nozzle body is reduced. At the same time, through the transmission system, the baffle is pushed to move left and right to adjust the water spray volume. The device has a novel design and simple operation. It can not only quickly adjust the height of the nozzle body by rotating the adjustment handle to improve the use effect, but also control the movement of the baffle through the transmission system to quickly adjust the water spray volume of the nozzle body. However, in this solution, when adjusting the water spray volume of the nozzle, the baffle is pushed to move left and right to adjust the water spray volume. However, over time, the continuous high-pressure liquid flowing through the nozzle hole causes corrosion. This flow gradually removes the metal and enlarges the orifice. As a result, the flow rate increases, the pressure decreases, the spraying pattern becomes irregular, and there is a phenomenon of insufficient supply. In addition, the material selection of the nozzle is also crucial. According to the type of liquid to be sprayed and the environment of the nozzle, the nozzle hole and the nozzle body will corrode. Therefore, an adjustable nozzle is needed to improve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: Please refer to Figures 1-4An adjustable nozzle shown includes a main body 1. An adjusting component 2 is arranged inside the main body 1. A feeding component 3 is fixedly connected to the side of the main body 1. A spraying component 4 is fixedly connected to the side of the feeding component 3;

[0026] In this embodiment, referring to Figure 1 , Figure 2 and Figure 3 shown, the adjusting component 2 includes a telescopic rod 201. The output end of the telescopic rod 201 is fixedly connected to a waterproof plate 202. A connecting rod 203 is fixedly connected to the side of the waterproof plate 202. A piston plate 204 is fixedly connected to the side of the connecting rod 203. The feeding component 3 includes an adapter plate 301. A micro pump 304 is installed on the top of the adapter plate 301. A feeding pipe 305 is fixedly connected to the top of the micro pump 304. A first chamber 302 is opened inside the adapter plate 301. By using the telescopic function of the telescopic rod 201, the waterproof plate 202, the connecting rod 203 and the piston plate 204 make piston movements in the first chamber 302 and the second chamber 402, so as to automatically and efficiently control the size of the liquid spray. The piston type flow regulation has strong adaptability, a wide range, and is not affected by the pressure level, and can adapt to a wide pressure range, so that the liquid can achieve the purpose of precise quantitative delivery.

[0027] Among them, the waterproof plate 202, the connecting rod 203 and the piston plate 204 are arranged inside the first chamber 302. The waterproof plate 202, the connecting rod 203 and the piston plate 204 make piston movements inside the first chamber 302 under the telescopic action of the telescopic rod 201. A input pipe 303 is fixedly connected to the bottom of the micro pump 304. The input pipe 303 extends into the first chamber 302. By using the micro pump 304, the mechanical energy of the prime mover or other external energy can be transmitted to the liquid when transporting the liquid, so that the liquid energy increases, and further the liquid transportation is increased, and the spraying efficiency of the liquid is improved. Because the inertial force of the rotating parts in the pump is low, a very high rotation speed can be used, and the suction performance is good, and it has self-priming ability.

[0028] In this embodiment, referring to Figure 1 and Figure 4As shown, the main body 1 includes a protective sleeve 101. Inside the protective sleeve 101, a loading pipe 102 is fixedly connected. On the side of the protective sleeve 101, a nylon sleeve 103 is provided. The loading pipe 102 is arranged inside the nylon sleeve 103. The spraying assembly 4 includes a supporting cross plate 401. Inside the supporting cross plate 401, a second chamber 402 is formed. The first chamber 302 communicates with the second chamber 402. On the side of the supporting cross plate 401, an additional orifice plate 403 is fixedly connected. On the side of the additional orifice plate 403, a delivery pipe 404 is fixedly connected. The second chamber 402 communicates with the delivery pipe 404. On the side of the delivery pipe 404, a protective orifice plate 405 is fixedly connected. On the side of the protective orifice plate 405, a silicon carbide nozzle pipe 406 is fixedly connected. The silicon carbide nozzle pipe 406 has remarkable characteristics such as high strength, high hardness, high wear resistance, high temperature resistance, and corrosion resistance. Its hardness is second only to diamond. It can withstand high-speed impact and high pressure. At the same time, it also has excellent self-lubricating performance. This can reduce the wear of the nozzle and extend its service life.

[0029] In this solution, when an adjustable nozzle is in use, a micro pump 304 is used to transport the liquid to be sprayed from the feed pipe 305 to the input pipe 303, and finally into the first chamber 302. Subsequently, the telescopic rod 201 can be used to push the waterproof plate 202, the connecting rod 203, and the piston plate 204 to advance simultaneously by its telescopic movement. Thus, the liquid injected into the first chamber 302 can be extruded and advanced. At this time, the liquid will enter the second chamber 402 and finally be sprayed out from the silicon carbide nozzle pipe 406 under the action of pressure. The telescopic speed of the telescopic rod 201 determines the strength of the silicon carbide nozzle pipe 406.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
