Description

Technical Field

[0001] This utility model relates to the field of gas spray heads, specifically a gas spray head with anti-clogging function. Background Technology

[0002] In industrial production, laboratory environments, and various application scenarios, gas spray heads are key components for gas dispersion and spraying, and their performance and stability are of paramount importance. Traditional gas spray head designs often overlook the impact of tiny particles or lint that may be carried in the gas on the spraying effect. These impurities can easily accumulate at the gas outlet of the spray head, causing blockages and affecting the uniform distribution of gas and spraying efficiency.

[0003] To address this issue, some improved gas spray heads have emerged on the market. However, these products are often complex in structure, have high maintenance costs, and may still experience clogging after prolonged use. Therefore, developing a gas spray head that is simple in structure, easy to maintain, and has a highly efficient anti-clogging function is particularly important. Utility Model Content

[0004] The purpose of this invention is to provide a gas spray head with anti-clogging function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gas spray head with anti-clogging function, comprising a hexagonal substrate, a screw connector fixed on the top surface of the hexagonal substrate, a protective cover fixed on the bottom surface of the hexagonal substrate, a plurality of air outlet holes opened on the surface of the protective cover, a connecting ring inserted into the screw connector, and a metal mesh cover one and a metal mesh cover two fixed on the surface of the connecting ring.

[0006] Preferably, the protective cover has an inverted frustum frame structure, with multiple air vents arranged at equal intervals and of equal size along the outer ring surface of the protective cover.

[0007] Preferably, a retaining ring is fixed to the inner wall of the screw connector, the connecting ring overlaps the retaining ring, and a limiting clip is provided between the connecting ring and the retaining ring.

[0008] Preferably, the limiting device includes a slot, a guide ring, and a rubber sleeve. The slot is an arc-shaped annular groove, which is opened on the top surface of the retaining ring. The guide ring is inserted into the slot and fixed to the bottom surface of the connecting ring. A rubber sleeve is fitted and fixed at the bottom end of the guide ring. The rubber sleeve has a circular cross-section and is clamped between the guide ring and the slot.

[0009] Preferably, the first metal mesh cover has a circular tube structure, the outer diameter of the first metal mesh cover is equal to the inner diameter of the screw joint, and the second metal mesh cover has a frustum frame structure.

[0010] Preferably, a pull ring is fixed to the top surface of the connecting ring. The pull ring is in the shape of a "U" and is located between the first metal mesh cover and the second metal mesh cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The gas spray head with anti-clogging function proposed in this utility model forms an effective particulate matter filtration barrier by setting a connecting ring inside the screw joint and fixing metal mesh cover one and metal mesh cover two on the connecting ring. The groove area between metal mesh cover one and metal mesh cover two can collect blocked particles or lint, ensuring that the gas can flow smoothly to the air outlet after passing through metal mesh cover two, thereby effectively avoiding the problem of air outlet clogging.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit 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.

[0020] Please see Figures 1-5This utility model provides a technical solution: a gas spray head with anti-clogging function, including a hexagonal base plate 1, a screw connector 2 fixed on the top surface of the hexagonal base plate 1, a protective cover 3 fixed on the bottom surface of the hexagonal base plate 1, and multiple air outlets 4 opened on the surface of the protective cover 3. The protective cover 3 has an inverted frustum frame structure, and the multiple air outlets 4 are arranged at equal distances and of equal size along the outer ring surface of the protective cover 3. The screw connector 2 is screwed to the air outlet of the air gun or screwed to the connector of the air supply pipe. After the gas enters the protective cover 3, it is sprayed out through the multiple air outlets 4.

[0021] A connecting ring 6 is inserted into the inside of the screw connector 2. A retaining ring 5 is fixed to the inner wall of the screw connector 2. The connecting ring 6 overlaps the retaining ring 5. Metal mesh cover one 10 and metal mesh cover two 11 are fixed to the surface of the connecting ring 6. Metal mesh cover one 10 has a cylindrical structure, and the outer diameter of metal mesh cover one 10 is equal to the inner diameter of the screw connector 2. Metal mesh cover two 11 has a frustum frame structure. A pull ring 12 is fixed to the top surface of the connecting ring 6. The pull ring 12 has a "U" shaped rod and is located between metal mesh cover one 10 and metal mesh cover two 11. Before the gas transmission equipment, the screw connector 2 is installed. The connecting ring 6 is pushed into the screw connector 2, connecting the metal mesh cover 10 and the metal mesh cover 21. The connecting ring 6 overlaps the retaining ring 5. After the screw connector 2 is installed, the metal mesh cover 10 and the metal mesh cover 21 are used to block particulate matter or lint. The blocked objects are collected in the trough area between the metal mesh cover 10 and the metal mesh cover 21, ensuring that the gas can pass through the top plate of the metal mesh cover 21 and flow down, thus avoiding the problem of blockage of the gas outlet 4.

[0022] A limiting device is provided between the connecting ring 6 and the retaining ring 5. The limiting device includes a slot 7, an guide ring 8, and a rubber sleeve 9. The slot 7 is an arc-shaped annular groove. The slot 7 is opened on the top surface of the retaining ring 5. The guide ring 8 is inserted into the slot 7 and fixed to the bottom surface of the connecting ring 6. The bottom end of the guide ring 8 is fitted and fixed with a rubber sleeve 9. The rubber sleeve 9 is a circular ring structure with a circular cross-section. The rubber sleeve 9 is clamped between the guide ring 8 and the slot 7. After the connecting ring 6 overlaps the retaining ring 5, the guide ring 8 and the rubber sleeve 9 are inserted into the slot 7 to achieve traction and limiting of the connecting ring 6 and prevent the connecting ring 6 from bumping on the retaining ring 5.

[0023] The procedure for using a gas spray head with anti-clogging function is as follows:

[0024] Push the connecting ring 6, along with the metal mesh covers 10 and 11, into the screw connector 2. Ensure that the guide ring 8 and rubber sleeve 9 on the connecting ring 6 are aligned with the groove 7 on the retaining ring 5. Gently push the connecting ring 6 to fully insert the guide ring 8 and rubber sleeve 9 into the groove 7, achieving a secure locking and limiting connection. Verify that the rubber sleeve 9 is firmly clamped between the guide ring 8 and the groove 7, ensuring that the connecting ring 6 does not wobble inside the screw connector 2. Screw the screw connector 2 onto the air outlet of the air gun or the connector of the air supply pipe, as needed. Turn on the gas source; the gas will enter the protective cover 3 through the screw connector 2 and be filtered by the metal mesh covers 10 and 11. The gas will then be evenly sprayed out through multiple air outlets 4 on the surface of the protective cover 3. Observe whether the gas spray is uniform and check for any signs of blockage in the air outlets 4. If a decrease in gas flow or uneven spray is observed, stop the machine immediately for inspection. Turn off the gas source and disconnect the screw connector 2 from the gas source. Gently pull out connecting ring 6, metal mesh cover 10, and metal mesh cover 2 11 using pull ring 12 to clean up accumulated particles or lint. Inspect the metal mesh cover and rubber sleeve for wear or damage, and replace them if necessary. Reassemble and connect the gas source for continued use.
