Description

Technical Field

[0001] This utility model relates to the field of air pump housings, specifically a housing for a portable air pump. Background Technology

[0002] A portable air pump is a practical tool used to quickly provide sufficient gas to various inflatable items. Its shell is usually made of high-strength, lightweight engineering plastic, which is not only sturdy and durable, effectively resisting collisions and wear in daily use, but also greatly reduces the overall weight, making it convenient for users to carry with them. It can easily handle outdoor travel, daily household use, or emergency scenarios.

[0003] Portable air pumps typically use rubber tubing for inflation. Since the tubing is usually detachable from the pump body, users often remove it when not in use to save space, facilitate storage, and prevent performance degradation due to prolonged bending. However, because the tubing is small and flexible, it's easily forgotten or mixed in with other items, making it difficult to find. If the tubing is lost, the user cannot use the portable air pump when urgently needed, such as when a tire suddenly leaks air and requires emergency inflation to reach a repair shop. If the tubing is missing, even if the pump itself is functioning normally, it will be unusable, causing significant inconvenience, disrupting travel plans, and resulting in unnecessary financial losses. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a housing for a portable air pump to solve the technical problem that existing portable air pumps have detachable rubber tubes that are easily lost after being removed, which prevents them from being properly inflated when urgently needed, thus causing inconvenience to users, affecting travel arrangements, and causing economic losses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable air pump housing, comprising an air pump housing, the air pump housing comprising a housing body, an inflation tube provided on one side of the housing body, the inflation tube comprising a mounting base, the mounting base being fixedly connected to the housing body, and a corrugated pipe provided on one side of the mounting base;

[0006] The bellows is provided with an air nozzle connector at the end away from the mounting base. The air nozzle connector can be threaded to an external air nozzle. A window breaker cone is provided on one side of the air nozzle connector.

[0007] By adopting the above technical solution, the inflation tube is fixedly connected to the outer shell through the mounting base, avoiding the risk of loss of the traditional detachable tube; the expansion and contraction characteristics of the corrugated tube allow for flexible adaptation to tire valves of different angles; the window breaker cone integrated into the valve connector provides an emergency window breaking escape function.

[0008] Furthermore, a bolt groove is provided on the other side of the outer shell body, and a storage box is provided on one side of the bolt groove. A bolt is provided on one side of the storage box, and the bolt is screwed into the bolt groove to fix the storage box to the outer shell body.

[0009] By adopting the above technical solution, the storage box is fixed by bolts and bolt slots, which enables quick disassembly and maintenance; the independent enclosed space centrally stores accessories such as air nozzles, preventing accessories from being scattered or lost.

[0010] Furthermore, a cover plate is rotatably connected to the other side of the storage box via a torsion spring shaft, and a locking bolt is provided on the top of the storage box to fix the cover plate.

[0011] By adopting the above technical solution, the torsion spring shaft enables the cover to automatically open and close, supporting one-handed opening and closing operation; the locking bolt provides forced locking of the cover to prevent parts from falling off accidentally.

[0012] Furthermore, the storage box is equipped with a cotton pad inside, and a plurality of receiving slots are provided on one side of the cotton pad, which are used to receive air nozzles.

[0013] By adopting the above technical solution, the cushioning structure of the cotton pad reduces collision damage when the air nozzle is stored; the receiving groove separates and fixes air nozzles of different specifications to prevent them from being damaged by mutual friction.

[0014] Furthermore, a display screen is provided on the outer surface of the main body of the outer casing, and a button is provided on one side of the display screen.

[0015] By adopting the above technical solution, the display screen shows the tire pressure value in real time to avoid over-inflation; the button integrates start / stop and mode switching functions, simplifying the operation process.

[0016] Furthermore, the main body of the outer shell is rectangular in shape, with rounded corners.

[0017] By adopting the above technical solutions, the rectangular shell body optimizes the internal circuit layout space; the rounded corners reduce accidental bumps and damage.

[0018] Furthermore, the window-breaking cone is made of high-strength alloy material, and its tip is hardened.

[0019] By adopting the above technical solutions, the high-strength alloy material improves the structural strength of the window-breaking cone; the quenching treatment of the tip enhances the penetrating power to break through tempered glass.

[0020] Furthermore, the outer shell body is made of high-strength engineering plastic, and its surface is treated with a frosted finish.

[0021] By adopting the above technical solutions, the engineering plastic shell body reduces the overall weight of the device, making it easier to carry; the frosted surface enhances grip and anti-slip properties.

Multiple storage slots of different sizes are opened on the inner cotton pad, which can orderly store different types of air nozzles to meet diverse inflation needs. In addition, the window-breaking cone on one side of the air nozzle connector is made of high-strength alloy material and the tip is quenched. In an emergency, it can help users break windows to escape, further improving the practicality and safety of the portable air pump. It solves the technical problems of existing portable air pumps, which have detachable rubber tubes that are easy to lose after removal, resulting in the inability to inflate normally when needed. At the same time, the lack of effective storage for different types of air nozzles and emergency window-breaking function causes inconvenience to users, affects travel arrangements, and causes economic losses.

[0029] 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.

[0030] Example 1: A housing for a portable air pump, such as Figure 1-4 As shown, it includes an air pump housing 1, which includes a housing body 101. An inflation pipe 2 is provided on one side of the housing body 101. The inflation pipe 2 includes a mounting base 201, which is fixedly connected to the housing body 101. A corrugated pipe 202 is provided on one side of the mounting base 201.

[0031] A valve connector 203 is provided at the end of the corrugated tube 202 away from the mounting base 201. The valve connector 203 can be threaded to an external valve. A window breaker cone 204 is provided on one side of the valve connector 203. The fixed connection between the mounting base 201 and the outer shell 101 ensures that the inflation tube 2 is always attached to the air pump body, eliminating the problem of loss caused by separate storage of traditional detachable rubber tubes. The flexible telescopic structure of the corrugated tube 202 allows it to be freely bent to the tire valve position during operation, and can be compressed and stored to reduce space occupation when not in use. The window breaker cone 204 is directly integrated on the side of the valve connector 203, which expands the window breaking operation range by utilizing the extension length of the inflation tube 2, and can quickly break the car window without additional tools in the event of a vehicle accident.

[0032] Example 2: See Figure 1 , Figure 2 , Figure 3 , Figure 4 A bolt groove is provided on the other side of the outer shell 101, and a storage box 104 is provided on one side of the bolt groove. A bolt is provided on one side of the storage box 104, and the bolt is screwed into the bolt groove to fix the storage box 104 to the outer shell 101. The bolt groove provided on the side of the outer shell 101 and the bolt of the storage box 104 form a detachable screwed connection structure, which allows the storage box 104 to be quickly installed or removed according to the usage requirements, and facilitates cleaning or replacement of parts inside the storage box 104. This split design makes the storage box 104 a physically isolated sealed space, which centrally stores small accessories such as air nozzles and window breaker cones 204 in a fixed position, preventing accessories from being separated from the air pump body and lost during transportation or storage.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4On the other side of the storage box 104, a cover plate 106 is rotatably connected via a torsion spring shaft 105. A locking bolt 107 is provided on the top of the storage box 104, and the locking bolt 107 is used to fix the cover plate 106. The mechanical structure of the torsion spring shaft 105 causes the cover plate 106 to automatically spring open when unlocked, reducing operation steps. Users can open the storage box 104 with one hand to take out and release the air valve. When closed, the torsion spring shaft 105 provides the initial closing force, and then the tightening of the locking bolt 107 applies additional pressure, so that a rigid seal is formed between the cover plate 106 and the storage box 104, preventing the cover plate 106 from accidentally opening and causing accessories to fall out when the vehicle is bumpy or during transportation.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The storage box 104 has a cotton pad 108 inside. The cotton pad 108 has multiple receiving slots 109 on one side, which are used to receive the air nozzles. The elastic material of the cotton pad 108 inside the storage box 104 absorbs the vibration and impact during transportation, preventing the metal parts of the air nozzles from colliding with the hard inner wall of the storage box 104 and causing deformation or scratches. The independent separation design of the multiple receiving slots 109 allows air nozzles of different sizes to be embedded in the corresponding slots, restricting their movement inside the box, preventing the air nozzles from colliding with each other and causing thread damage or contamination of the sealing surface, thus extending the service life of the accessories.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The outer surface of the main body 101 is provided with a display screen 102, and a button 103 is provided on one side of the display screen 102. The display screen 102 on the outside of the main body 101 directly displays the current inflation pressure value. Users can accurately control the inflation process without relying on an independent tire pressure gauge, avoiding the risk of tire blowout caused by overinflation. The adjacent button 103 integrates the functions of starting and stopping the air pump, switching PSI / kPa, and preset tire pressure through logic circuits, simplifying the traditional multi-step operation into a single-button trigger, reducing the probability of misoperation in complex environments.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main body 101 has a rectangular design with rounded corners. The rectangular structure of the main body 101 provides regular assembly space for the internal air pump motor, battery pack and circuit board, ensuring that the components are compactly arranged to reduce the overall size. The rounded corners eliminate sharp edges and disperse the impact force when the air pump is dropped or collides with items in the vehicle, reducing the risk of cracking of the main body 101, while also improving the grip and avoiding cuts.

[0037] See Figure 1, Figure 2 , Figure 3 , Figure 4 The 204 window breaker cone is made of high-strength alloy material. Its tip is hardened. The high-strength alloy matrix of the 204 window breaker cone is not easy to break when subjected to high-speed impact, ensuring reliability in emergency window breaking. The tip is locally hardened to form an ultra-high hardness surface layer, which allows the cone to penetrate the prestress layer of the vehicle's tempered glass. Compared with ordinary metal cones, it reduces the number of impacts and improves escape efficiency.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The outer shell 101 is made of high-strength engineering plastic with a frosted surface. The high-strength engineering plastic material allows the outer shell 101 to maintain its pressure resistance while significantly reducing its weight, improving the portability for users to hold and inflate with one hand. The frosted texture on the surface increases the friction coefficient between the hand and the outer shell 101, preventing the air pump from slipping due to hand sweat or oil during operation, and ensuring safety in humid environments.

[0039] The implementation principle of this embodiment is as follows: First, the inflation tube 2 of the air pump housing 1 is fixed to the housing body 101 via the mounting base 201, forming an integrated structure. This ensures that the corrugated tube 202 does not need to be disassembled after use, avoiding the risk of loss due to separate storage. The flexible design of the corrugated tube 202 allows it to be bent and stored when not in use, saving space and preventing long-term bending deformation. The air nozzle connector 203 can be threadedly connected to an external air nozzle and can be removed after inflation.

[0040] Secondly, the storage box 104 is bolted to the bolt slot of the outer shell 101 to form a detachable storage unit, which facilitates the direct storage of the air nozzle connector 203 and the window breaker cone 204, preventing them from being forgotten among other items. The cover 106 is opened and closed by rotating the torsion spring shaft 105, and the locking bolt 107 ensures that the cover 106 is sealed and secure when locked. The multiple receiving slots 109 of the internal cotton pad 108 are adapted to the size of the air nozzle connector 203, providing cushioning protection and isolating moisture, so that the air nozzle and window breaker cone 204 are not easily overlooked or lost during storage.

[0041] The rectangular design of the main body 101, combined with rounded corners, enhances grip comfort; the display screen 102 and button 103 are used to display and control inflation parameters in real time, improving ease of operation. The window breaker cone 204 is made of high-strength alloy material with a hardened tip for emergency window breaking needs; the engineering plastic material of the main body 101 is frosted to ensure wear resistance and slip resistance.

[0042] The overall structure ensures that the air nozzle is always attached through the integrated inflation tube 2 and the fixed storage box 104, eliminating the problem of loss caused by separate storage and ensuring the reliable use of the portable air pump in sudden emergency situations.
