Description

Technical Field

[0001] This utility model relates to the field of nozzle equipment, specifically a noise-reducing nozzle with adjustable nozzle core. Background Technology

[0002] A nozzle, also known as a spray head or spray nozzle, is a component used to spray fluid substances. It is generally tubular with a small outlet end. It is a key component in many types of spraying, misting, oil spraying, sandblasting, and coating equipment, and is widely used in agricultural irrigation, industrial manufacturing, fire rescue, and daily life.

[0003] With the development of technology, the materials, structure, and performance of nozzles have been continuously improved and perfected. From the initial cast iron materials to today's various materials such as metals, plastics, ceramics, and alloys, the lifespan and performance of nozzles have been significantly improved. At the same time, with the continuous development of spray technology, parameters such as the spray shape, flow rate, pressure, and atomized particle size of nozzles have also been precisely controlled, making the application range of nozzles more extensive. However, in the process of nozzle application, it has been found that the nozzles on the market generally only have one spray mode, that is, the fluid material is sprayed out from the nozzle orifice, and the spray method is single. In order to meet the fluid material spraying needs in different environments, this application proposes a noise reduction nozzle with nozzle core adjustment. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a noise-reducing nozzle with adjustable nozzle core, so as to solve the technical problem of the single spraying mode of existing nozzles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing nozzle with adjustable nozzle core, comprising a core and a nozzle sleeve. The bottom end of the core is provided with an annular groove, and the top end of the nozzle sleeve is embedded in the annular groove and slidably sleeved with the core. A first nozzle is assembled at the bottom end of the nozzle sleeve, and a conical surface is provided at the bottom end of the nozzle sleeve. Multiple second nozzles are arranged on the conical surface at the bottom end of the nozzle sleeve. A rubber plug capable of blocking the second nozzles is provided at one end of the core embedded in the nozzle sleeve. A spray channel is vertically opened in the core, and a guide hole is opened in the rubber plug, the guide hole connecting the inner cavity of the nozzle sleeve and the spray channel.

[0006] The present invention is further configured such that the outer wall of the top end of the nozzle sleeve is threadedly engaged with the outer circular surface inside the annular groove.

[0007] The present invention is further configured such that a plurality of sealing rings are sleeved at the bottom end of the core, and the sealing rings are in interference contact with the inner cavity of the nozzle sleeve.

[0008] The present invention is further configured such that the bottom end of the rubber plug is configured as an arc-shaped structure, and the diameter of the guide hole gradually increases from top to bottom.

[0009] The present invention is further configured such that a spray hole is provided on the inner wall of the nozzle sleeve at a position corresponding to the first nozzle and the second nozzle, the spray hole connecting the first nozzle, the second nozzle and the inner cavity of the nozzle sleeve, and the diameter of the spray hole gradually decreases from the inner cavity of the nozzle sleeve outward.

[0010] The present invention is further configured such that a threaded head is provided at the top of the core, and a sealing washer fitted onto the threaded head is provided on the top surface of the core.

[0011] The present invention is further configured such that a groove is provided on the outer wall of the core, and a protruding ridge is provided at the bottom of the outer wall of the nozzle sleeve.

[0012] In summary, the present invention has the following main advantages:

[0013] This invention utilizes the nested cooperation of the core and the nozzle sleeve. When the nozzle sleeve is screwed upward, the rubber plug at the bottom of the core penetrates into the inner cavity of the nozzle sleeve and blocks the second nozzle. At this time, the medium can only be sprayed through the first nozzle. When the nozzle sleeve is screwed downward, the rubber plug at the bottom of the core moves upward inside the nozzle sleeve. At this time, the rubber plug no longer blocks the second nozzle, and the medium can be sprayed out dispersedly through the second nozzle and the first nozzle. It has a spray adjustment function and is suitable for the medium spraying needs in different scenarios.

[0014] This invention features a design where the guide holes on the rubber plug gradually increase in diameter from top to bottom. This design reduces pressure on the medium as it passes through the injection channel and guide holes into the nozzle sleeve cavity, thus reducing the impact of the medium on the nozzle sleeve. In addition, the rubber material of the rubber plug also helps to reduce noise. The design where the injection holes gradually decrease in diameter from the inner cavity of the nozzle sleeve outwards also increases the pressure on the medium as it exits from the inner cavity of the nozzle sleeve through the first and second nozzles, ensuring the injection pressure and providing excellent injection performance.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] A noise-reducing nozzle with adjustable nozzle core, such as Figures 1-4 As shown, the device includes a core 1 and a nozzle sleeve 2. The bottom of the core 1 has an annular groove 9. The top of the nozzle sleeve 2 is inserted into the annular groove 9 and slidably fitted with the core 1. A first nozzle 4 is mounted on the bottom of the nozzle sleeve 2. A conical surface is provided at the bottom of the nozzle sleeve 2, and multiple second nozzles 14 are arranged on the conical surface. A rubber plug 10 capable of sealing the second nozzles 14 is provided at one end of the core 1 embedded in the nozzle sleeve 2. A vertical injection channel 8 is formed inside the core 1. A guide hole 13 is formed inside the rubber plug 10, connecting the inner cavity of the nozzle sleeve 2 and the injection channel 8. Through this structure, the core 1 is connected to a media conveying pipeline, which then transports media. The mass flow enters the inner cavity of the nozzle sleeve 2 through the injection channel 8 and the guide hole 13. At this time, the medium can be diverted through the injection hole 12 and dispersed by the first nozzle 4 and the second nozzle 14. When the nozzle sleeve 2 is pushed upward, the rubber plug 10 at the bottom of the core 1 enters the inner cavity of the nozzle sleeve 2 and blocks the second nozzle 14. At this time, the medium can only be sprayed through the first nozzle 4. When the nozzle sleeve 2 is pulled down, the rubber plug 10 at the bottom of the core 1 moves up inside the nozzle sleeve 2. At this time, the rubber plug 10 no longer blocks the second nozzle 14, and the medium can be dispersed and sprayed through the second nozzle 14 and the first nozzle 4. It has the function of adjusting the injection mode and is suitable for the medium injection needs in different scenarios.

[0022] Furthermore, the outer wall of the nozzle sleeve 2 is threaded into the outer circular surface inside the annular groove 9, allowing the nozzle sleeve 2 to move up and down by screwing it, thus adjusting the spray pattern. A raised ridge 6 is provided at the bottom of the outer wall of the nozzle sleeve 2 to facilitate screwing. This screwing mechanism also allows the nozzle sleeve 2 to be detached from the core 1 by screwing it, facilitating assembly, maintenance, and cleaning.

[0023] Furthermore, the bottom end of the core 1 is fitted with multiple sealing rings 11, which are in interference contact with the inner cavity of the nozzle sleeve 2, and are used to seal between the nozzle sleeve 2 and the core 1 during the up and down movement of the nozzle sleeve 2.

[0024] Furthermore, the bottom end of the rubber plug 10 is designed with an arc shape, and the diameter of the guide hole 13 gradually increases from top to bottom. Injection holes 12 are provided on the inner wall of the nozzle sleeve 2 at positions corresponding to the first nozzle 4 and the second nozzle 14. The injection holes 12 connect the first nozzle 4, the second nozzle 14, and the inner cavity of the nozzle sleeve 2. The diameter of the injection holes 12 gradually decreases from the inner cavity of the nozzle sleeve 2 outwards. Because the diameter of the guide hole 13 on the rubber plug 10 gradually increases from top to bottom, the medium will be depressurized when it enters the inner cavity of the nozzle sleeve 2 through the injection channel 8 and the guide hole 13, reducing the impact of the medium on the nozzle sleeve 2. In addition, the rubber material of the rubber plug 10 can also reduce noise. Through the structural design of the injection hole 12 gradually decreasing in diameter from the inner cavity of the nozzle sleeve 2 outwards, the medium is pressurized when it is ejected from the inner cavity of the nozzle sleeve 2 from the first nozzle 4 and the second nozzle 14, ensuring the medium injection pressure.

[0025] Furthermore, a threaded head 3 is provided at the top of the core 1, and a sealing washer 7 is provided on the top surface of the core 1 and fitted on the threaded head 3. The threaded head 3 is used to connect the core 1 with the medium conveying pipeline. A groove 5 is provided on the outer wall of the core 1, and the groove 5 is used for unscrewing the core 1.

[0026] The working principle of this utility model is as follows: In use, the core 1 is connected to the medium conveying pipeline through the threaded head 3. The medium conveying pipeline transports the medium through the injection channel 8 and the guide hole 13 into the inner cavity of the nozzle sleeve 2. At this time, the medium can be diverted through the injection hole 12 and dispersed and sprayed out by the first nozzle 4 and the second nozzle 14. By twisting the nozzle sleeve 2 upward, the rubber plug 10 at the bottom of the core 1 enters the inner cavity of the nozzle sleeve 2 and blocks the second nozzle 14. At this time, the medium can only be sprayed through the first nozzle 4. By twisting the nozzle sleeve 2 downward, the rubber plug 10 at the bottom of the core 1 moves upward inside the nozzle sleeve 2. At this time, the rubber plug 10 no longer blocks the second nozzle 14, and the medium can be dispersed and sprayed out through the second nozzle 14 and the first nozzle 4. It is suitable for the medium spraying needs in different scenarios. Furthermore, since the guide hole 13 on the rubber plug 10 gradually increases in diameter from top to bottom, the medium will be depressurized when it enters the inner cavity of the nozzle sleeve 2 through the injection channel 8 and the guide hole 13, reducing the impact of the medium on the nozzle sleeve 2. In addition, the rubber material of the rubber plug 10 can also reduce noise. Through the structural design of the injection hole 12 gradually decreasing in diameter from the inner cavity of the nozzle sleeve 2 to the outer cavity, the medium is pressurized when it is ejected from the inner cavity of the nozzle sleeve 2 from the first nozzle 4 and the second nozzle 14, ensuring the medium injection pressure and possessing excellent medium injection performance.
