Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically an air pump with a multi-functional quick-connect structure. Background Technology

[0002] In outdoor camping, wilderness exploration, sports and fitness scenarios, air pumps are a tool used to quickly inflate equipment such as air mattresses, tents, sports balls, and swimming rings, and their convenience and practicality have attracted much attention; with the diversification of outdoor activities, users' functional needs for air pumps are also becoming increasingly diverse.

[0003] Most ordinary air pumps on the market have limited functions. In outdoor environments, users often need to address other needs, such as ventilation when camping or temporary cooling in high-temperature environments. Ordinary air pumps cannot provide additional assistance in these situations. At the same time, different inflatable devices (such as air mattresses, balls, inflatable toys, etc. of different sizes) usually require specific models of air nozzles, while the air nozzles of ordinary air pumps are usually fixed. The replacement process is cumbersome and time-consuming, which affects the applicability and flexibility of the product and limits the comprehensive application capability of air pumps in multiple scenarios. Utility Model Content

[0004] The purpose of this invention is to provide an air pump with a multi-functional quick-connect structure, which has the advantages of multi-functional adjustment, quick replacement of air nozzles and portable storage, and solves the problems of single function and poor flexibility of outdoor use of existing air pumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An air pump with a multi-functional quick-connect structure includes a protective assembly. The protective assembly includes a protective housing, inside which a drive assembly is installed. The drive assembly includes a mounting base fixed to the lower inner wall edge of the protective housing. The upper end of the mounting base has a left-right extending slide groove. A slider is slidably mounted on the inner wall of the slide groove. A motor base is fixed to the upper end of the slider. A servo motor is mounted on the inner wall of the motor base. A rotating frame is fixed to the front end of the mounting base. Gear shaft 1 and gear shaft 2, distributed left and right, are rotatably mounted on the end of the rotating frame near the output end of the servo motor. A drive gear is fixed to the output end of the servo motor, and the drive gear is located between the gears of gear shaft 1 and gear shaft 2. The drive assembly also includes a cylinder fixed to the lower inner wall of the protective housing. The gear of gear shaft 2 drives the piston in the cylinder to move through a reciprocating structure. An air inlet pipe is installed at the output end of the cylinder. A fan is fixed to the front edge of the protective housing. The rotating shaft of the fan is connected to the rotating shaft of gear shaft 1. An electric cylinder is fixed to the right end of the mounting base. The output end of the electric cylinder is fixed to the outer wall of the motor base.

[0006] Preferably, the front end of the protective box is also equipped with a light and a controller, and the drive assembly also includes a battery fixed to the inner edge of the rear end wall of the protective box.

[0007] It is worth noting that the controller can operate the devices within the drive assembly, allowing them to cooperate to meet inflation or heat dissipation needs as required. The lighting provides illumination, and the battery provides power to the devices within the drive assembly and the lighting.

[0008] Preferably, the protective assembly also includes a base fixed to the lower end of the protective box and a handle rotatably mounted on the upper end of the protective box.

[0009] It is worth noting that the base can protect the bottom of the protective box, preventing damage caused by friction between the bottom of the protective box and the ground. The rotating handle can be flipped to fit against the outer wall of the protective box when the device is placed to reduce the footprint, and can be unfolded for easy gripping when the device needs to be moved.

[0010] Preferably, an inflation assembly is installed at the right end of the protective box. The inflation assembly includes a protective box fixed to the right end of the protective box, a fixing box fixed to the inner wall of the protective box, a plurality of inflation nozzles in the fixing box, and a protective plate hinged to the opening at the right end of the protective box.

[0011] It is worth noting that the inflation components can be used to inflate different items as needed, the protective box and protective plate can protect the fixed box, and the fixed box can limit and protect various types of inflation nozzles, thus enabling the carrying of various types of inflation nozzles and adapting to the inflation of various items.

[0012] Preferably, the air inlet end of the air nozzle is fixedly connected to a quick connector, and the inside of the protective box is provided with a coiled air tube. One end of the air tube is connected to the air outlet end of the cylinder, and the other end of the air tube is adapted to the quick connector.

[0013] It is worth noting that the protective box can also store and protect the inflation tube. One end of the inflation tube is connected to the air outlet of the cylinder, which can guide the airflow from the cylinder to the other end of the inflation tube. The quick connector can quickly fix the inflation nozzle into the air outlet of the inflation tube and facilitate disassembly and replacement.

[0014] Preferably, the reciprocating structure includes a rocker arm rotatably mounted on the outer wall of the gear shaft, and a guide rail fixed to the right end of the rotating frame and extending to the left and right. A sliding block is fixed to the end of the rocker arm, and the sliding block is slidably mounted in the guide rail. The piston rod in the cylinder is fixed to the outer wall of the sliding block.

[0015] It is worth noting that: by driving the gear shaft two to rotate through the servo motor, the rocker arm can be driven to swing back and forth. The moving rocker arm can continuously push and pull the sliding block to move left and right along the inner wall of the guide rail, converting rotation into linear motion, which in turn drives the piston to achieve reciprocating motion, so that the cylinder can achieve intake and exhaust.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses an electric cylinder to push the motor base, causing the slider to slide stably along the groove on the mounting base. This adjusts the lateral position of the servo motor, enabling the drive gear to mesh with either gear shaft one or gear shaft two. This ensures the stability of the gear transmission and allows for adjustments to the transmission based on the airflow requirements of different inflation scenarios. Simultaneously, the servo motor, through the drive gear, can synchronously drive either gear shaft one or gear shaft two to rotate. Gear shaft one can directly drive the fan to operate, providing cooling for personnel or outdoor tents and improving comfort during outdoor use. Gear shaft two, through a reciprocating structure, drives the piston in the cylinder to reciprocate, generating airflow. The airflow is then transported to the subsequent inflation structure via the inflation pipe, achieving synchronous coordination of cooling and inflation functions. This effectively improves the device's working efficiency and continuous operation capability. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To address the limitations of existing air pumps in terms of limited functionality and poor flexibility for outdoor use, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-5 ; An air pump with a multi-functional quick-connect structure includes a protective assembly. The protective assembly includes a protective housing 101, inside which a drive assembly is installed. The drive assembly includes a mounting base 301 fixed to the lower inner wall edge of the protective housing 101. The upper end of the mounting base 301 has a left-right extending slide groove 302. A slider 303 is slidably mounted on the inner wall of the slide groove 302. A motor base 304 is fixed to the upper end of the slider 303. A servo motor 305 is mounted on the inner wall of the motor base 304. A rotating frame 306 is fixed to the front end of the mounting base 301. A left-right distributed gear shaft 308 is rotatably mounted on the end of the rotating frame 306 near the output end of the servo motor 305. The output end of the servo motor 305 is fixedly connected to a drive gear 307, which is located between the gears of the first gear shaft 308 and the second gear shaft 309. The drive assembly also includes a cylinder 311 fixedly connected to the inner wall of the lower end of the protective box 101. The gear of the second gear shaft 309 drives the piston in the cylinder 311 to move through the reciprocating structure 310. An air inlet pipe 202 is installed at the output end of the cylinder 311. A fan 103 is fixedly connected to the front edge of the protective box 101. The rotating shaft of the fan 103 is connected to the rotating shaft of the first gear shaft 308. An electric cylinder 312 is fixedly connected to the right end of the mounting base 301. The output end of the electric cylinder 312 is fixedly connected to the outer wall of the motor base 304.

[0021] The electric cylinder 312 can push the motor base 304, causing the slider 303 to slide stably along the slide groove 302 on the mounting base 301, thereby adjusting the lateral position of the servo motor 305. This enables the drive gear 307 to mesh with either gear shaft 308 or gear shaft 309, ensuring the stability of the gear transmission and allowing for adjustments to the transmission based on the airflow requirements of different inflation scenarios. Simultaneously, the servo motor 305 can drive either gear shaft 308 or gear shaft 309 to rotate via the drive gear 307. Gear shaft 308 can directly drive the fan 103 to operate, providing cooling for personnel or outdoor tents and improving comfort during outdoor use. Gear shaft 309, through the reciprocating structure 310, drives the piston in the cylinder 311 to reciprocate, generating airflow. The airflow is then transported to the subsequent inflation structure via the inflation pipe 202, achieving synchronous coordination of cooling and inflation functions and effectively improving the device's working efficiency and continuous operation capability.

[0022] Please see Figure 3The protective box 101 is equipped with a light 104 and a controller 105 at its front end. The drive assembly also includes a battery 313 fixed to the inner edge of the rear end wall of the protective box 101. The controller 105 can control the equipment inside the drive assembly, and the equipment inside the drive assembly can cooperate to complete the inflation or heat dissipation needs as needed. The light 104 can provide lighting, and the battery 313 can provide power to the equipment inside the drive assembly and the light 104. The protective assembly also includes a base 102 fixed to the lower end of the protective box 101 and a handle 106 rotatably mounted on the upper end of the protective box 101. The base 102 can protect the lower end of the protective box 101 to prevent the lower end of the protective box 101 from being damaged by friction with the ground. The rotatably mounted handle 106 can be flipped to fit against the outer wall of the protective box 101 when the device is placed to reduce the footprint, and can be unfolded for easy gripping when the device needs to be moved.

[0023] Please see Figure 4 An inflation assembly is installed at the right end of the protective box 101. The inflation assembly includes a protective box 201 fixed to the right end of the protective box 101. A fixing box 203 is fixed to the inner wall of the protective box 201. Multiple inflation nozzles 204 are provided inside the fixing box 203. A protective plate 206 is hinged inside the opening at the right end of the protective box 201. Different items can be inflated as needed through the inflation assembly. The protective box 201 and the protective plate 206 can protect the fixing box 203. The fixing box 203 can limit and protect various inflation nozzles 204, thereby carrying various types of inflation nozzles 204 and adapting to the inflation of various items.

[0024] The air inlet end of the air nozzle 204 is fixedly connected to a quick connector 205. The inside of the protective box 201 is equipped with a coiled air tube 202. One end of the air tube 202 is connected to the air outlet end of the cylinder 311, and the other end of the air tube 202 is adapted to the quick connector 205. The protective box 201 can also store and protect the air tube 202. One end of the air tube 202 is connected to the air outlet end of the cylinder 311, which can guide the airflow ejected from the cylinder 311 to the other end of the air tube 202. The air nozzle 204 can be quickly fixed in the air outlet of the air tube 202 through the quick connector 205, and it is easy to disassemble and replace.

[0025] Please see Figure 5The reciprocating structure 310 includes a rocker arm rotatably mounted on the outer wall of the gear shaft 309, and a guide rail fixed to the right end of the rotating frame 306 and extending left and right. A sliding block is fixed to the end of the rocker arm and is slidably mounted in the guide rail. The piston push rod in the cylinder 311 is fixed to the outer wall of the sliding block. The servo motor 305 drives the gear shaft 309 to rotate, which drives the rocker arm to reciprocate. The moving rocker arm can continuously push and pull the sliding block to move left and right along the inner wall of the guide rail, converting rotation into linear motion, thereby driving the piston to achieve reciprocating motion, so that the cylinder 311 can achieve intake and exhaust.

[0026] Working principle: First, the battery 313, which is fixed to the inner edge of the rear end of the protective box 101, provides power to the servo motor 305, electric cylinder 312, air cylinder 311 and lighting lamp 104 in the drive assembly. The operator can use the controller 105 installed at the front end of the protective box 101 to precisely control the operating status of each device according to the actual use needs. If it is in a dark environment, the lighting lamp 104 can be turned on to provide lighting.

[0027] When the device needs to be adjusted to adapt to different scenarios, the controller 105 controls the electric cylinder 312 on the right end of the mounting base 301 to start. The output end of the electric cylinder 312 pushes the motor base 304, so that the slider 303 at the lower end of the motor base 304 slides stably along the left and right extended slide groove 302 opened at the upper end of the mounting base 301. This drives the servo motor 305 installed on the inner wall of the motor base 304 to move laterally, so as to achieve precise control of the meshing between the drive gear 307 fixed to the output end of the servo motor 305 and the gear shaft 308 or gear shaft 309 rotatably installed on the rotating frame 306. The servo motor 305 is started by the controller 105, which drives the drive gear 307 to rotate. The drive gear 307 meshes synchronously to drive the gear shaft 308 or the gear shaft 309 to rotate. Heat dissipation function: The rotating shaft of the gear shaft 308 is connected to the rotating shaft of the fan 103 fixed at the front edge of the protective box 101. The rotation of the gear shaft 308 directly drives the fan 103 to run, blowing air to dissipate heat for personnel or outdoor tents, improving the comfort of outdoor use. Inflation power generation: When the gear shaft 309 rotates, it drives the rocker arm in the reciprocating structure 310 mounted on the outer wall of its gear to swing. The sliding block fixed at the end of the rocker arm slides along the left and right extension guide rails fixed at the right end of the rotating frame 306. Since the piston push rod in the cylinder 311 is fixed to the outer wall of the sliding block, the linear motion of the sliding block pushes the piston to reciprocate in the cylinder 311, so that the cylinder 311 completes the intake and exhaust action, generating the airflow required for inflation.

[0028] Airflow delivery and inflation operation: The airflow generated by cylinder 311 is delivered through the inflation tube 202 connected to its output end. The inflation tube 202 is coiled and stored inside the protective box 201 fixed to the right end of the protective box 101. The protective box 201 serves to store and protect the inflation tube 202. The operator can open the protective plate 206 hinged inside the opening at the right end of the protective box 201 and take out the inflation nozzle 204 adapted to the item to be inflated from the fixing box 203 fixed to the inner wall of the protective box 201. Using the quick connector 205 fixed to the air inlet end of the inflation nozzle 204, the inflation nozzle 204 is quickly fixed to the air outlet end of the inflation tube 202. The airflow enters the inflation nozzle 204 through the inflation tube 202 and the quick connector 205, and finally completes the inflation operation of the target item. If it is necessary to change the inflated item, the corresponding inflation nozzle 204 can be quickly disassembled and replaced through the quick connector 205.
