Description

Technical Field

[0001] This utility model relates to the field of brushed material mattress technology, specifically to a high-pressure air nozzle. Background Technology

[0002] Brushed material mattresses are mattresses made of materials such as brushed fibers or brushed cloth. Brushed air mattresses use brushed cloth materials such as PVC or TPU, and are formed by inflation. They are portable, customizable, and multifunctional, and are suitable for various scenarios. Before using a brushed material mattress, it is necessary to inflate the mattress by connecting a hand pump through an air nozzle.

[0003] Currently, when using a hand pump air nozzle, there is a lack of a leak-proof mechanism. When the existing air nozzle is connected to the hand pump to inflate a mattress, the pressure inside the mattress increases, and gas will escape outward from the gaps, easily causing air leakage in the hand pump and affecting the mattress inflation efficiency. Since the high-pressure gas inside the mattress is prone to leakage, a high-pressure air nozzle is proposed to add a leak-proof mechanism. By using a thin sheet to support and cover the air outlet, air can be introduced on one side while the air outlet of the mattress is closed, preventing high-pressure gas inside the mattress from leaking from the air nozzle and hand pump, improving the stability and convenience of the inflation operation, and thus improving the user experience. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a high-pressure air nozzle, which enables air intake on one side while simultaneously closing the air outlet of the mattress, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a high-pressure air nozzle, which includes an air outlet, a connecting part and an air-sealing component, wherein the air outlet and the connecting part are provided with an air-sealing component. The air-tightening component includes an outer ring, inside which is a circular thin sheet. A connecting handle is provided between the outer ring and the circular thin sheet, and a flow channel is formed between the outer ring and the circular thin sheet.

[0006] By adopting the above technical solution, while inflating the air valve, the air outlet can be sealed with a thin sheet to automatically achieve the air-tight function of the mattress air outlet, thus preventing air leakage.

[0007] Specifically, the air outlet includes a retaining sleeve and an air nozzle cap, the retaining sleeve having an air outlet channel, the connecting part including a fixing sleeve and an air nozzle cover, the fixing sleeve being fitted onto the retaining sleeve, the fixing sleeve having a connecting channel being fitted onto the air outlet channel.

[0008] Specifically, the nozzle cover is provided with a connecting section, and the connecting section is connected to the connecting channel, and a support is provided between the connecting section and the connecting channel.

[0009] Specifically, a limiting component is provided in the air outlet channel, and a first sealing ring is provided on the surface of the sleeve.

[0010] Specifically, the inner surface of the fixing sleeve is provided with a second sealing ring, the outer surface of the connecting section is provided with a third sealing ring, and the air nozzle cover includes a protruding ridge.

[0011] The beneficial effects of this utility model are: The high-pressure air nozzle described in this utility model, through the design of an air outlet, a connecting part, an outer ring, a circular thin plate, and a guide channel, adds an air leakage prevention mechanism. By using the sliding and sealing method of the thin plate to block the air outlet, when high-pressure gas is pushed outward from inside the mattress, the air pressure supports the thin plate to automatically seal the air outlet channel. While air is being introduced on one side, the air outlet of the mattress is sealed off, preventing air leakage. This improves the inflation efficiency of the fibrous material mattress and makes it more stable and reliable in use.

[0012] The high-pressure air nozzle described in this utility model, through the setting of a clamp, air nozzle cap, fixing sleeve, air nozzle cover, connecting channel and air outlet channel, can improve the flexibility and convenience of using the high-pressure air nozzle by utilizing a splicing and combination structure. Moreover, it makes it convenient for subsequent operators to partially disassemble and replace damaged parts, reduce resource waste, and improve the practicality of use. Attached Figure Description

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] To prevent high-pressure gas from leaking from the air nozzle and hand pump inside the mattress, thereby improving performance, such as... Figure 1-2 As shown, the high-pressure air nozzle of this utility model includes an air outlet 1, a connecting part 2, and an air-sealing component 3, wherein the air outlet 1 and the connecting part 2 are provided with the air-sealing component 3. The air-tightening component 3 includes an outer ring 301, a circular thin plate 302 is provided inside the outer ring 301, a connecting handle 303 is provided between the outer ring 301 and the circular thin plate 302, and a flow guiding channel 304 is formed between the outer ring 301 and the circular thin plate 302.

[0017] When in use, as the hand pump inflates the mattress, the gas can quickly pass through the channel 304 of the outer ring 301 through the channel between the air outlet 1 and the connecting part 2, entering the mattress without obstruction and ensuring normal inflation efficiency. When the air pressure inside the mattress increases and the gas tends to push out in the opposite direction, the high-pressure gas exerts a thrust on the outer ring 301, pushing the outer ring 301 and the central thin plate 302 to slide towards the air outlet of the connecting part 2. Since the diameter of the central thin plate 302 is larger than that of the air outlet, it can automatically block the channel, achieving the air-sealing function of the mattress inflation port while inflating, thereby preventing gas from leaking back to the hand pump from the air nozzle, solving the air leakage problem caused by the lack of an active sealing structure in traditional air nozzles, and ensuring a stable inflation process.

[0018] Both the air outlet 1 and the connecting part 2 are made of ABS plastic.

[0019] The air-tightening component 3 is a one-piece molded structure.

[0020] To improve usability, for example, such as Figure 3 , Figure 4 As shown, the present invention also includes the following: the air outlet 1 includes a retainer 101 and an air nozzle cap 102, the retainer 101 has an air outlet channel 103, the connecting part 2 includes a fixing sleeve 201 and an air nozzle cover 202, the fixing sleeve 201 is fitted onto the retainer 101, the fixing sleeve 201 has a connecting channel 203, and the connecting channel 203 is fitted onto the air outlet channel 103.

[0021] In use, by aligning the fixing sleeve 201 of the connecting part 2 with the clamping sleeve 101 of the air outlet 1, the connecting channel 203 and the air outlet channel 103 are precisely aligned. Then, the fixing sleeve is pushed along the axis to complete the connection, thus forming a complete gas flow path. The overall splicing design not only facilitates quick assembly, but also allows for the replacement of only the corresponding damaged part when a component is damaged, without the need to replace the entire air nozzle, thus reducing usage costs and minimizing resource waste.

[0022] For example, such as Figure 2 As shown, the present invention also includes a connecting section 204 provided inside the air nozzle cover 202, and the connecting section 204 is connected to the connecting channel 203, and a support member 207 is provided between the connecting section 204 and the connecting channel 203.

[0023] In use, the connecting section 204 connects to the connecting channel 203, guiding the gas delivered by the hand pump to the air outlet 1. The diameter of the circular thin plate 302 is larger than the air outlet between the connecting channel 203 and the connecting section 204.

[0024] For example, such as Figure 3 As shown, the present invention also includes a limiting member 104 provided in the air outlet channel 103, and a first sealing ring 105 provided on the inner surface of the sleeve 101.

[0025] When in use, the limiting member 104 in the air outlet channel 103 can enhance the strength of the channel structure; the first sealing ring 105 in the sleeve 101, after the fixing sleeve 201 and the sleeve 101 are fitted together, is squeezed and deformed to fill the gap of the sleeve, blocking the path of gas leakage from the connection between the air outlet 1 and the connecting part 2, and making up for the sealing shortcomings of the sleeve structure.

[0026] For example, such as Figure 4 , 5 As shown, the present invention also includes a second sealing ring 206 provided on the inner surface of the fixing sleeve 201, a third sealing ring 208 provided on the outer surface of the connecting section 204, and the air nozzle cover 202 including a protruding rib 205.

[0027] During use, the second sealing ring 206 inside the fixing sleeve 201 and the first sealing ring 105 of the ferrule 101 form a "double annular seal", respectively covering different depth positions of the sleeve structure; the third sealing ring 208 outside the connecting section 204 fits tightly against the inner wall of the air inlet when the connecting section 204 is inserted into the hand pump connector, filling the interface gap and preventing gas leakage from the connection end between the air nozzle and the hand pump; the convex rib 205 on the outer wall of the air nozzle cover 202 can increase the grip friction of the hand, effectively preventing slippage when the operator installs or removes the air nozzle, making it easier to complete the insertion, removal and rotation operations, and improving the ease of use. The first sealing ring 105, the second sealing ring 206 and the third sealing ring 208 are all made of nitrile rubber.

[0028] When using this utility model, firstly, tightly insert the connector of the hand pump into the air nozzle cover 202 of the connecting part 2 to ensure that there is no obvious gap between the connector and the air nozzle cover 202. Then, align the fixing sleeve 201 of the connecting part 2 with the clamping sleeve 101 of the air outlet 1. After aligning the connecting channel 203 with the air outlet channel 103, push the fixing sleeve 201 to complete the fitting. The first sealing ring 105 and the second sealing ring 206 are deformed under pressure to achieve a sealed connection between the air outlet 1 and the connecting part 2. Then, rotate the air nozzle cap 102 of the air outlet 1 to connect to the air inlet of the wire-stretched mattress. Then, by repeatedly pulling the hand pump, the inflation gas pushes the circular thin plate 302 to slide towards the air outlet channel 103 until it abuts against the limiting member 104. The inflation gas passes through the hand pump connector, connecting section 204, connecting channel 203, outer ring 301, guide channel 304 and air outlet channel 103 in sequence, and finally enters the interior of the mattress. As the pressure inside the mattress increases, when there is a reverse pushout tendency of gas during manual inflation, the high-pressure gas pushes the outer ring 301 and the circular thin plate 302 to slide towards the air outlet of the connecting section 204 of the connecting part 2. Since the diameter of the circular thin plate 302 is larger than the air outlet of the connecting section 204, the circular thin plate 302 can completely block the air outlet of the connecting section 204, thereby preventing the high-pressure gas from leaking back. While inflating, the mattress inflation port is automatically sealed. Throughout the entire process, the active sealing of the air-sealing component 3, the passive sealing of multiple sealing rings, and the convenient maintenance of the spliced ​​structure effectively solve the problem of high-pressure gas leakage at the top of the traditional air nozzle during inflation, significantly improving the inflation efficiency and stability of the wire mesh mattress.
