Description

Technical Field

[0001] This utility model belongs to the field of fine water mist nozzles, specifically a fine water mist nozzle with adjustable atomization angle. Background Technology

[0002] A fine water mist nozzle is a device that can atomize liquids into tiny particles, producing very fine and uniform atomized particles. The maximum atomization diameter of the gas-liquid atomizing spray gun can reach 3um-4um, ensuring complete evaporation. The atomized water mist can cover a large area and make full contact with the target substance. It is widely used in many fields, such as industrial dust collector flue gas cooling, fire sprinkler, agricultural irrigation, and landscape design. When using a fine mist nozzle, an adjusting head is usually connected to the spray nozzle. By rotating the adjusting head, the spray angle can be changed. The adjusting head and the nozzle are generally connected by threads, and PTFE tape is wrapped around the connection to enhance the seal and prevent water leakage. However, during the adjustment process, the adjusting head needs to be rotated repeatedly, which causes the raw material belt at the connection to wear after multiple rotations. In addition, frequent rotation makes it difficult for the threads of the nozzle and the adjusting head to mesh properly, which can easily lead to leakage and thus affect the spraying effect.

[0003] In summary, this invention provides a fine water mist nozzle with an adjustable atomization angle to solve the above problems. Utility Model Content

[0014] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0015] Example 1 like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a fine water mist nozzle with an adjustable atomization angle, including a nozzle assembly 100, a rotating assembly 200, including an adjusting head 210, a connecting nut 220 sleeved on the upper end of the surface of the adjusting head 210, a limiting ring 230 fixed to the top of the adjusting head 210, a spring 240 rotatably connected to one end of the limiting ring 230, a guide surface 250 opened at the lower end of the surface of the adjusting head 210, and a sealing ring 260 for sealing the connection between the nozzle assembly 100 and the connecting nut 220, wherein the limiting ring 230 is located in the inner cavity of the connecting nut 220.

[0016] like Figure 1-5As shown, the nozzle assembly 100 includes a water mist chamber 110, an external threaded connector 120, a nozzle body 140, a first quick connector 150 and a second quick connector 160. The first quick connector 150 and the second quick connector 160 are used to quickly connect with external air pipes and water pipes to achieve the delivery of fine water mist. The rotating assembly 200 is used to adjust the atomization angle. By nesting the adjusting head 210 and the connecting nut 220, and forming an elastic support structure with the limiting ring 230 and the spring 240, the adjusting head 210 can remain stable during rotation, reducing sealing failure caused by offset or tilt. At the same time, the nozzle body 140 and the adjusting head 210 are connected in a movable manner, allowing angle adjustment without damaging the overall sealing structure. A sealing ring 260 is provided between the connecting nut 220 and the external threaded connector 120 to prevent water leakage during spraying. The spring 240 cooperates with the limiting ring 230 to provide an elastic limiting function for the adjusting head 210, ensuring that the adjusting head 210 will not come out during rotation and can automatically reset when adjustment stops, maintaining structural stability. The annular groove on the retaining ring 130 further enhances the positioning stability of the spring 240, preventing the spring 240 from offset and causing adjustment failure. When adjusting the atomization angle, simply push the adjusting head 210 upwards, causing the adjusting head 210 to move the limiting ring 230 upwards and compress the spring 240. Then, rotate the adjusting head 210 to change the spray angle. After the angle is adjusted, release the adjusting head 210. The restoring force of the spring 240 pushes the limiting ring 230 downwards, making the limiting ring 230 tightly contact the inner wall of the connecting nut 220. This effectively solves the problem of sealing failure caused by frequent rotation of traditional adjusting heads.

[0017] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0018] In this embodiment, the nozzle assembly 100 includes a water mist chamber 110, an external threaded connector 120 fixed to the bottom of the water mist chamber 110, a retaining ring 130 located at the bottom of the water mist chamber 110 and fixed to the inner cavity of the external threaded connector 120, a nozzle body 140 located in the inner cavity of the retaining ring 130, and a first quick interface 150 and a second quick interface 160 communicating with the surface of the water mist chamber 110.

[0019] The end of the external threaded connector 120 away from the water mist chamber 110 extends into the inner cavity of the connecting nut 220 and is threadedly connected to the inner cavity of the connecting nut 220. The sealing ring 260 contacts the connecting nut 220 and the external threaded connector 120 respectively.

[0020] The nozzle body 140 is connected to the inner cavity of the water mist chamber 110. The end of the nozzle body 140 away from the water mist chamber 110 extends into the inner cavity of the adjusting head 210 and is movably connected to the inner cavity of the adjusting head 210. The adjusting head 210 has a spray port that is adapted to the nozzle body 140.

[0021] The end of the spring 240 away from the limiting ring 230 contacts the retaining ring 130, and the surface of the retaining ring 130 is provided with an annular groove that is adapted to the spring 240.

[0022] like Figure 1-4 As shown, the water mist chamber 110 serves as the main cavity of the entire device, providing buffering and mixing space for the water flow. The external threaded connector 120 connects to the rotating assembly 200. The retaining ring 130 is used to limit the spring 240. The nozzle body 140 controls the spraying of fine water mist through the spray nozzle. The first quick connector 150 and the second quick connector 160 are used to connect to the external water pipe and air pipe. The adjusting head 210 serves as the center of rotation adjustment, and the direction of water flow is adjusted through the guide surface 250 on its surface. The connecting nut 220 is used to connect the nozzle assembly 100 to the adjusting head 210. Its inner cavity accommodates the limiting ring 230, which is fixed to the top of the adjusting head 210 and rotatably connected to one end of the spring 240 to control the rotation range of the adjusting head 210. The guide surface 250 is opened at the lower end of the adjusting head 210, so that the water flow can still flow smoothly at different angles. The sealing ring 260 is set between the connecting nut 220 and the external threaded connector 120 to ensure sealing.

[0023] Example 3 Reference Figure 1 and 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0024] In this embodiment, an adjustment assembly 300 is installed on the top of the nozzle assembly 100. The adjustment assembly 300 includes a knob 310 located at the top of the nozzle assembly 100, a limiting seat 320 located at the upper end of the inner cavity of the water mist chamber 110, a pin 330 slidably connected to the inner cavity of the limiting seat 320, a first compression spring 340 located at the top of the limiting seat 320, and a second compression spring 350 located at the upper end of the pin 330.

[0025] The bottom of the ejector pin 330 passes through the limiting seat 320 and extends into the inner cavity of the nozzle body 140, and is movably connected to the inner cavity of the nozzle body 140. The knob 310 is threadedly connected to the top of the water mist chamber 110. One end of the first compression spring 340 contacts the top of the limiting seat 320, and the other end contacts the top of the inner cavity of the water mist chamber 110. One end of the second compression spring 350 is sleeved on the upper end of the surface of the ejector pin 330, and the other end contacts the inner wall of the knob 310.

[0026] like Figure 1 and5 As shown, the adjustment component 300 is used to adjust the mist flow rate of the nozzle body 140. The rotation of the adjustment component controls the movement of the ejector pin 330. The limiting seat 320 is fixed to the top of the inner cavity of the water mist chamber 110, providing a sliding guide for the ejector pin 330. The ejector pin 330 acts directly on the inner cavity of the nozzle body 140. The opening of the spray nozzle is controlled by moving up and down. The first compression spring 340 connects the limiting seat 320 and the inner wall of the water mist chamber 110, providing a restoring force. The second compression spring 350 connects the knob 310 and the ejector pin 330, enhancing the stability of the adjustment. When the knob 310 is rotated, it drives the ejector pin 330 to move downward. The ejector pin 330 inserts into the inner cavity of the nozzle body 140, changing the flow area of ​​the spray nozzle, thereby adjusting the mist size. The first compression spring 340 and the second compression spring 350 work together to ensure that the knob 310 has good rebound and adjustment feedback.

[0027] When in use, rotate the knob 310. The rotation of the knob 310 will drive the ejector pin 330 to move downward. During the movement, the ejector pin 330 will gradually insert into the inner cavity of the nozzle body 140, thereby changing the flow area of ​​the spray nozzle. When it is necessary to increase the amount of mist output, rotate the knob 310 in reverse to move the ejector pin 330 away from the nozzle body 140 and expand the opening of the spray nozzle. Thus, the amount of mist output can be easily adjusted according to actual needs. As the core component of atomization, the nozzle assembly 100 has a water mist chamber 110 that connects to the fluid through a first quick-connect port 150 and a second quick-connect port 160. The external threaded connector 120 and the connecting nut 220 of the rotating assembly 200 are threaded together to achieve a stable connection. The retaining ring 130 provides axial restraint to the nozzle body 140 to ensure the coaxiality of the spray nozzle and the adjusting head 210. In the rotating assembly 200, the adjusting head 210 can rotate around the nozzle body 140. During the rotation, the guide surface 250 guides the atomized fluid to form a specific spray angle. The limiting ring 230 and the spring 240 cooperate to limit the rotation range of the adjusting head 210. The sealing ring 260 effectively prevents fluid leakage at the connection, realizing the dynamic sealing and angle adjustment functions of the nozzle assembly 100 and the rotating assembly 200.
