Description

Technical Field

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

[0002] Brushed material mattresses are inflatable mattresses made using a brushed material process. In recent years, they have been widely used in outdoor camping and home spare bedding. These mattresses usually require a hand pump connected to an air nozzle for rapid inflation, and the air nozzle must have good one-way sealing performance to prevent gas leakage after inflation.

[0003] Currently used air nozzle connectors typically employ complex multi-component structures. These structures involve numerous parts, complex assembly processes, and high production costs. Furthermore, under high pressure, sealing reliability may decrease, leading to air leakage. The complex internal channel structure can also cause airflow obstruction and low inflation efficiency. Therefore, a unidirectional high-pressure air nozzle connector is proposed. Through a simple structural design, it utilizes the air pressure difference to automatically control the opening and closing of the silicone gasket, achieving unidirectional high-efficiency inflation and reliable sealing, thereby improving the performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a one-way high-pressure air nozzle connector, which allows for automatic control of the opening and closing of the silicone gasket using air pressure difference, thereby achieving one-way efficient inflation and reliable sealing, thus improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a one-way high-pressure air nozzle connector, including a middle section, an air inlet section and an air outlet section. An air inlet section is provided on one side of the middle section and an air outlet section is provided on the other side of the middle section. A flow guide channel is opened in the middle section and the air outlet section is connected to the flow guide channel. A small parasol assembly is fixedly installed in the flow guide channel on one side of the air inlet section.

[0006] The small parasol assembly includes a circular pad, a fixing post at the top of the circular pad, an umbrella-shaped protrusion at one end of the fixing post, and a guide post at the top of the umbrella-shaped protrusion.

[0007] By adopting the above technical solution, the function of one side air intake and one side air closure can be achieved by utilizing air pressure difference, thereby improving the stability of high-pressure inflation of the mattress.

[0008] Specifically, a pressure gauge is provided at the top of the intermediate section, and the pressure gauge includes a threaded connector.

[0009] Specifically, a positioning hole is provided between the flow guide channel and the air intake section, and an air intake circular hole is provided at equal intervals around the positioning hole in the flow guide channel, and the air intake circular hole is connected to the air intake section.

[0010] Specifically, a mounting base is provided at the top of the intermediate section, and a threaded hole is provided in the mounting base. The threaded hole is connected to a threaded joint through a thread, and the threaded hole is connected to a flow guide channel. A sealing gasket is provided between the pressure gauge and the mounting base.

[0011] Specifically, an annular groove corresponding to the umbrella-shaped protrusion is provided on one side of the positioning hole in the air intake section, and the annular groove is connected to the positioning hole. A positioning post is provided on the outer surface of the air intake section.

[0012] Specifically, the surface of the air outlet section is provided with a sliding groove.

[0013] The beneficial effects of this utility model are:

[0014] (1) The one-way high-pressure air nozzle connector described in this utility model simplifies the one-way inflation structure by setting an intermediate section, an air inlet section, an air outlet section and a small parasol assembly. It has fewer parts and is easy to assemble, which effectively reduces production costs and failure rate. Moreover, it automatically controls opening and closing by using air pressure difference. When sealing in reverse, the higher the pressure, the tighter the umbrella-shaped protrusion and the annular groove are pressed together, resulting in excellent sealing effect. It is especially suitable for filament mattresses that need to maintain high internal pressure.

[0015] (2) The one-way high-pressure air nozzle connector described in this utility model, through the setting of pressure gauge, threaded connector, mounting base and threaded hole, adds air pressure detection mechanism, which can monitor the air pressure in the guide channel in real time, so that users can keep track of the inflation status of the wire material mattress and avoid over-inflation or under-inflation affecting the use effect.

[0023] 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.

[0024] To facilitate automatic control of the opening and closing of the silicone gasket using air pressure difference, achieving unidirectional efficient inflation and reliable sealing, thereby improving performance, such as... Figure 1-3 As shown, the one-way high-pressure air nozzle connector of this utility model includes a middle section 1, an air inlet section 2 and an air outlet section 3. The air inlet section 2 is provided on one side of the middle section 1, and the air outlet section 3 is provided on the other side of the middle section 1. A flow guide channel 101 is opened in the middle section 1, and the air outlet section 3 is connected to the flow guide channel 101. A small parasol assembly 4 is fixedly provided in the flow guide channel 101 on one side of the air inlet section 2.

[0025] The small parasol assembly 4 includes a circular pad 401, a fixing post 402 is provided on the top of the circular pad 401, an umbrella-shaped protrusion 403 is provided at one end of the fixing post 402, and a guide post 404 is provided on the top of the umbrella-shaped protrusion 403.

[0026] During use, gas enters from the air inlet section 2 and flows through the air inlet hole 103 into the guide channel 101. At this time, the gas pressure pushes the circular gasket 401 of the small parasol assembly 4, causing the circular gasket 401 to separate from the sealing surface in the guide channel 101. The gas then smoothly passes through the guide channel 101 into the air outlet section 3 and finally fills the filament mattress. When the air pressure inside the mattress reaches a certain level or when inflation stops, the gas inside the mattress acts in the opposite direction on the circular gasket 401, making it tightly fit the sealing surface, thus achieving a one-way seal and preventing gas leakage.

[0027] The small parasol component 4 is made of silicone.

[0028] The middle section 1, the air intake section 2, and the air outlet section 3 are integrally molded structures.

[0029] To improve the accuracy of the inflation operation, for example, such as Figure 1 , Figure 5 As shown, the present invention also includes a pressure gauge 5 provided at the top of the intermediate section 1, the pressure gauge 5 including a threaded connector 501.

[0030] During use, the air pressure in the airflow channel 101 can be transmitted to the pressure gauge 5 in real time. By observing the value of the pressure gauge 5, the user can accurately understand the inflation pressure of the brushed material mattress and avoid damage to the mattress due to over-inflation or insufficient inflation affecting the user experience.

[0031] For example, such as Figure 2 As shown, the present invention also includes a positioning hole 102 between the flow channel 101 and the air intake section 2, and an air intake circular hole 103 is provided at equal intervals around the positioning hole 102 in the flow channel 101, and the air intake circular hole 103 is connected to the air intake section 2.

[0032] During use, the positioning hole 102 can guide and limit the fixing post 402 of the small parasol assembly 4, ensuring that the small parasol assembly 4 opens and closes in a fixed direction under air pressure, avoiding displacement that affects the sealing effect; while the equidistantly distributed air inlet holes 103 on the periphery can allow gas to enter the guide channel 101 evenly, reduce airflow impact, and at the same time ensure air intake and improve inflation efficiency. There are 6 air inlet holes 103.

[0033] For example, such as Figure 4 , 5 As shown, the present invention also includes a mounting base 104 at the top of the intermediate section 1, a threaded hole 105 in the mounting base 104, and the threaded hole 105 is connected to a threaded connector 501 by a thread, and the threaded hole 105 is connected to a flow channel 101. A sealing gasket 6 is provided between the pressure gauge 5 and the mounting base 104.

[0034] During use, the mounting base 104 provides a stable mounting foundation for the pressure gauge 5. The engagement of the threaded hole 105 and the threaded connector 501 enables the detachable connection of the pressure gauge 5, facilitating future maintenance or replacement of the pressure gauge 5. The sealing gasket 6 fills the gap between the pressure gauge 5 and the mounting base 104, preventing gas in the guide channel 101 from leaking from the installation gap, thus ensuring the accuracy of air pressure monitoring and overall sealing performance.

[0035] For example, such as Figure 2 , 4 As shown, the present invention also includes an annular groove 201 corresponding to the umbrella-shaped protrusion 403, located on one side of the positioning hole 102 in the air intake section 2, and the annular groove 201 communicates with the positioning hole 102, and a positioning post 202 is provided on the outer surface of the air intake section 2.

[0036] During use, the annular groove 201 cooperates with the umbrella-shaped protrusion 403 to fix and limit the small parasol assembly 4, preventing the small parasol assembly 4 from shifting or falling off during long-term use and ensuring structural stability; the positioning post 202 on the outer surface of the air inlet section 2 can play a positioning role when connected to the inflation device, making it convenient to quickly align the interface, improve connection efficiency, and enhance the stability after connection, avoiding gas leakage due to loose interface during inflation.

[0037] For example, such as Figure 4 As shown, the present invention also includes a sliding groove 301 formed on the surface of the air outlet section 3.

[0038] When in use, when the air outlet section 3 is connected to the air inlet of the filament mattress, the sliding groove 301 can cooperate with the corresponding structure inside the mattress air inlet. This not only makes it easy to insert or remove the air outlet section 3, reducing the difficulty of operation, but also enhances the tightness of the connection through structural cooperation, preventing the two from separating due to external force during the inflation process, and ensuring that the inflation process is stable. The sliding groove 301 consists of a vertical section and a horizontal section.

[0039] In use, the air inlet section 2 is first connected to the hand pump. The positioning post 202 is used to quickly align and fix the interface. Then, the air outlet section 3 is inserted into the air inlet of the brushed material mattress. The sliding groove 301 and the mattress air inlet structure cooperate to achieve a tight connection. Then, the hand pump is operated to inflate the mattress. The gas enters from the air inlet section 2 and flows evenly into the guide channel 101 through the air inlet hole 103. The air pressure pushes the circular pad 401 of the small parasol component 4 to separate it from the sealing surface. The gas is then filled into the mattress through the guide channel 101 and the air outlet section 3.

[0040] During inflation, the user can monitor the air pressure in real time through the pressure gauge 5 at the top of the middle section 1. Once the appropriate pressure is reached, inflation is stopped. After inflation stops, the reverse air pressure inside the mattress presses the circular pad 401 against the sealing surface, completely covering and blocking the air inlet hole 103, making it difficult for gas to pass through. This achieves one-way sealing, completes the automatic air-locking function, and prevents gas leakage. The whole process is simple, efficient, and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
