Description

Technical Field

[0001] This utility model belongs to the field of air inflator technology, and more specifically, it relates to an inner tube air inflator that facilitates air intake and sealing. Background Technology

[0002] An inflation nozzle is a specialized interface device used to inject or release gas into a closed container (such as a tire, airbag, or air cushion). It is typically a key component of an airtight system, ensuring that gas enters and exits the container efficiently and in a controlled manner.

[0003] Based on existing technology, it has been found that when using the existing air inflator, gas can be introduced by contacting the internal valve core through the connector and compressing the spring. The spring has a limited lifespan, and if the spring fails, it will cause the air inflator to not seal properly, which is a certain defect. In addition, when using the existing air inflator, when it is necessary to release air, a tool is required to press the valve core to release air, which is inconvenient to operate and cannot be done quickly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an inner tube inflator nozzle that facilitates air intake and sealing. This addresses the issue that existing inflator nozzles require a connector to contact the internal valve core and compress a spring to allow air to enter. However, the spring has a limited lifespan, and if it fails, the nozzle will not seal properly, resulting in certain defects. Furthermore, existing inflator nozzles require tools to press the valve core to release air when deflation is needed, which is inconvenient and prevents quick deflation.

[0005] This utility model provides an inner tube inflation nozzle that facilitates air intake and sealing, achieved through the following specific technical means:

[0006] An inner tube inflator that facilitates air intake and sealing includes an inflation part, a pressing part, an installation part, and a sealing part;

[0007] The inflation part is provided with a pressing part; the mounting part is located inside the inflation part; the sealing part is located inside the mounting part;

[0008] The inflatable part includes: a main body; the top of the main body is provided with threads, and the inner wall of the main body is provided with threads; a through circular hole is provided inside the main body;

[0009] The mounting part includes: a mounting component, the top of which is threaded; the mounting component is installed inside the main body; and a retaining ring is provided inside the mounting component.

[0010] The sealing part includes: a valve core disposed inside the mounting component; a spring B fitted on the top of the valve core; the bottom of the spring B connected to a fixing ring; a sealing element disposed on the top of the valve core; the bottom of the sealing element connected to the spring B; the sealing element inserted into a circular hole on the mounting component; and a magnet disposed on the top of the sealing element.

[0011] Furthermore, the inflation part also includes: a sealing cap;

[0012] The sealing cap is located on the top of the main body; a rubber gasket is provided at the top of the inside of the sealing cap.

[0013] Furthermore, the pressing part includes: a pressing element, a spring A, and a plug;

[0014] The pressing component is located on the side of the main body; the pressing component is connected to spring A; spring A is fixedly located inside a circular hole on the main body; the side of the plug-in is set with an inclined structure; the plug-in is slidably installed inside a circular hole on the main body; the plug-in is slidably installed inside a circular hole on the mounting component; the plug-in is fixedly located on the pressing component.

[0015] Furthermore, the mounting component is made of metal iron; a valve core is slidably disposed inside the circular hole of the fixing ring.

[0016] Furthermore, the sealing part also includes: a fixing block;

[0017] The top of the fixing block is configured as a frustum-shaped structure; the fixing block is fixedly mounted on the valve core; the top side of the fixing block is in contact with the inclined side of the plug-in.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this device, a sealing element and a magnet are provided. The sealing element is fixedly installed on the valve core, while the magnet is installed on the sealing element. Thus, when the valve core contacts the connector of the air pump hose during use, the needle inside the air pump hose contacts the valve core, which drives the valve core to compress the spring B. This allows gas to enter the inner tube through the round hole on the mounting part. After inflation, the spring B returns to its original position, and the magnet attracts the mounting part, ensuring that the sealing element can be stably inserted into the round hole on the mounting part, thus better ensuring the sealing performance.

[0020] 2. This device includes a plug and a fixing component. The plug is fixedly connected to the pressing component, while the fixing component is fixedly installed on the valve core. This allows the sealing cap to be removed during use. By manually pushing the pressing component, the pressing component compresses the spring A, causing the inclined edge of the plug to contact the frustum-shaped structure on the top of the fixing block. This pushes the valve core downward and causes the sealing component to disengage from the round hole of the mounting component, thus enabling quick deflation of the inner tube and making the operation more convenient.
