Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a nozzle for a spraying device. Background Technology

[0002] Existing sprinkler systems are mostly used for spraying fluids. In their internal structure, spray holes are often set on the nozzle, which allows the inside of the nozzle to communicate with the outside. However, in use, it can be found that different specifications and distribution types of spray holes have a direct impact on the fluid at the spraying point. In order to be suitable for various application scenarios, existing nozzles often have accessories (panels with spray holes of different specifications) connected to the nozzle end. The most common way to connect accessories is to use threaded connections. Although threaded connections are quick, their sealing performance is generally poor. When the fluid pressure is high and the threaded connection is not tight, fluid leakage may occur. Utility Model Content

[0003] The purpose of this invention is to provide a spray nozzle for a spraying device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a spray head for a spraying device, comprising a spray head body and a spray hole panel, wherein a connecting structure is provided between the spray head body and the spray hole panel;

[0005] The connection structure includes a fixing ring and a connecting pipe. The fixing ring is fixedly installed on the inner wall of the nozzle body port. The top end of the connecting pipe communicates with the inside of the spray hole panel. A sealing ring is fixedly installed at the bottom of the fixing ring. The inner diameter of the sealing ring is smaller than the inner diameter of the fixing ring. The inner diameter of the sealing ring in its unexpanded state is smaller than the outer diameter of the connecting pipe. The connecting pipe passes through the sealing ring. An integrally formed extension pressure ring is provided on the outer wall of the connecting pipe. The outer diameter of the extension pressure ring is the same as the inner diameter of the fixing ring. The extension pressure ring presses on the protruding part of the sealing ring. An installation body is fixedly sleeved on the outer wall of the connecting pipe. An elastic sheet is fixedly installed on the outer wall of the installation body. The connection between the elastic sheet and the installation body is close to the bottom end of the installation body. The top end of the elastic sheet extends into the fixing ring. The middle section of the elastic sheet protrudes. An arc-shaped groove is opened on the inner wall of the fixing ring. The middle section of the elastic sheet is inserted into the arc-shaped groove.

[0006] An adjustable connecting seat is provided at the bottom of the nozzle body.

[0007] Furthermore, multiple elastic sheets and arc-shaped slots are provided and distributed in a circumferential array. A toggle ring is fixedly installed on the top of the elastic sheet. The toggle ring is slidably sleeved on the connecting tube and connected to all the elastic sheets.

[0008] Furthermore, the adjustable connecting seat includes a rotating ball and a ball seat. The rotating ball is integrally formed with the nozzle body, and a through hole communicating with the interior of the nozzle body is opened at the center of the rotating ball. The rotating ball is rotatably disposed in the ball seat, and a sealing gasket is provided in the gap between the rotating ball and the ball seat.

[0009] Furthermore, a one-way valve is provided at the bottom end of the ball seat, and the outer wall of the port of the one-way valve is threadedly connected to the inner wall of the bottom end of the ball seat.

[0011] Furthermore, the outer wall of the actuating ring is provided with an integrally formed extension body, the bottom of which has a groove, and the extension body corresponds to the positioning protrusion at the top port of the nozzle body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the fluid pressure inside the nozzle body acts on the connecting pipe, the connecting pipe will be forced to move outward from the nozzle body. At this time, the elastic sheet is deformed by the force, which makes the protrusion in the middle of the elastic sheet larger, so that the elastic sheet can be more stably locked into the arc-shaped groove, preventing the connecting pipe from coming off the nozzle body, thus achieving stable installation and good sealing.

[0014] 2. A ball seat is set up to install the rotating ball. Because the rotating ball can rotate within the ball seat, the nozzle body can be adjusted to a certain angle. The sealing gasket forms a sealing layer between the rotating ball and the ball seat, and also increases the friction and resistance experienced by the rotating ball, so that the rotating ball will not easily change after rotating a certain angle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 The present invention provides a technical solution: a spray head for a spraying device, comprising a spray head body 1 and a spray hole panel 2, wherein a connecting structure 3 is provided between the spray head body 1 and the spray hole panel 2;

[0022] The connecting structure 3 includes a fixing ring 301 and a connecting pipe 303. The fixing ring 301 is fixedly installed on the inner wall of the nozzle body 1 port. The top end of the connecting pipe 303 communicates with the inside of the spray hole panel 2. A sealing ring 302 is fixedly installed at the bottom of the fixing ring 301. The inner diameter of the sealing ring 302 is smaller than the inner diameter of the fixing ring 301. The inner diameter of the sealing ring 302 in its unexpanded state is smaller than the outer diameter of the connecting pipe 303. The connecting pipe 303 passes through the sealing ring 302. An integrally formed extension pressure ring 306 is provided on the outer wall of the connecting pipe 303. The outer diameter of the extended pressure ring 306 is the same as the inner diameter of the fixed ring 301. The extended pressure ring 306 presses against the protruding part of the sealing ring 302. The outer wall of the connecting pipe 303 is fixedly fitted with a mounting body 307. An elastic piece 304 is fixedly installed on the outer wall of the mounting body 307. The connection between the elastic piece 304 and the mounting body 307 is near the bottom end of the mounting body 307. The top end of the elastic piece 304 extends into the outside of the fixed ring 301. The middle section of the elastic piece 304 protrudes. The inner wall of the fixed ring 301 is provided with an arc-shaped groove 305. The middle section of the elastic piece 304... The segment is inserted into the arc-shaped groove 305. Because the inner diameter of the sealing ring 302 is smaller than that of the fixing ring 301, and the inner diameter of the sealing ring 302 in its unexpanded state is smaller than the outer diameter of the connecting pipe 303, the connecting pipe 303 can expand the sealing ring 302 as it passes through it, causing the sealing ring 302 to deform and thus increasing the contact area with the connecting pipe 303. This ensures the seal between the connecting pipe 303 and the sealing ring 302. After the fluid pressure inside the nozzle body 1 acts on the connecting pipe 303, the connecting pipe 303 will be subjected to force. As the nozzle body 1 moves outward, the elastic sheet 304 deforms under force, increasing the protrusion in the middle of the elastic sheet 304. This allows the elastic sheet 304 to be more stably inserted into the arc-shaped groove 305, preventing the connecting pipe 303 from detaching from the nozzle body 1. This achieves stable installation and good sealing. During disassembly, simply pull the elastic sheet 304, traction on its upper end, causing the elastic sheet 304 to gradually straighten and reduce the protrusion, allowing it to detach from the arc-shaped groove 305, thus completing the installation.

[0023] An adjustable connecting seat 4 is provided at the bottom of the nozzle body 1 for making small adjustments to the angle of the nozzle body 1;

[0024] Multiple elastic sheets 304 and arc-shaped slots 305 are provided and distributed in a circumferential array to increase the connection points, making the connection between the connecting tube 303 and the fixing ring 301 more stable and firm. A toggle ring 5 is fixedly installed on the top of the elastic sheet 304. The toggle ring 5 is slidably sleeved on the connecting tube 303 and connected to all the elastic sheets 304. The toggle ring 5 is set to pull all the elastic sheets 304 at the same time.

[0025] The adjustable connecting seat 4 includes a rotating ball 401 and a ball seat 402. The rotating ball 401 is integrally formed with the nozzle body 1, and a through hole communicating with the interior of the nozzle body 1 is opened at the center of the rotating ball 401. The rotating ball 401 is rotatably disposed in the ball seat 402. A sealing gasket 403 is provided in the gap between the rotating ball 401 and the ball seat 402. The ball seat 402 is provided for mounting the rotating ball 401. Because the rotating ball 401 can rotate in the ball seat 402, the nozzle body 1 can be adjusted to a certain angle. The sealing gasket 403 forms a sealing layer between the rotating ball 401 and the ball seat 402, and also increases the friction and resistance of the rotating ball 401, so that the rotating ball 401 will not easily change after rotating a certain angle.

[0026] A one-way valve 9 is provided at the bottom of the ball seat 402. The outer wall of the port of the one-way valve 9 is threadedly connected to the inner wall of the bottom of the ball seat 402 to prevent the fluid in the nozzle body 1 from flowing back.

[0027] The ball seat 402 is equipped with a filter element 8, which is located in the space between the one-way valve 9 and the rotating ball 401. When the fluid is liquid, it filters the impurities in the liquid to prevent impurities from clogging the spray holes in the spray hole panel 2.

[0028] The outer wall of the actuating ring 5 is provided with an integrally formed extension body 6. The bottom of the extension body 6 is provided with a groove, and the extension body 6 corresponds to the positioning protrusion 7 at the top port of the nozzle body 1. The extension body 6 is provided to facilitate the user toggling the actuating ring 5. When toggling, the user can insert their finger into the groove and then toggle. The positioning protrusion 7 is provided to position the elastic sheet 304 so that the elastic sheet 304 can be aligned with the arc-shaped slot 305.

[0029] Working principle: During use, the connecting pipe 303 is inserted into the sealing ring 302. During the insertion process, the connecting pipe 303 is in a state of deformation under force. After the elastic piece 304 is aligned with the arc-shaped groove 305, the elastic piece 304 returns to its original deformation and is inserted into the arc-shaped groove 305, thus completing the installation of the spray hole panel 2. When the fluid pressure acts on the bottom of the connecting pipe 303, the connecting pipe 303 moves under force, which in turn drives the mounting body 307 to move. When the force on the mounting body 307 is transmitted to the elastic piece 304, it will cause the protrusion in the middle section of the elastic piece 304 to become more obvious, and then it can be inserted into the arc-shaped groove 305 more tightly, so that the connecting pipe 303 can not move further, preventing the spray hole panel 2 from falling off.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
