Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically a foldable and retractable outdoor air pump. Background Technology

[0002] With the increasing popularity of outdoor sports, camping, and self-driving tours, portable inflatable devices (such as inflatable mattresses, inflatable tents, and swimming rings) are being used more and more widely, and air pumps, as accessories for these devices, have become one of the essential pieces of equipment for outdoor travel.

[0003] Most commercially available air pumps adopt an integrated design, with the core inflation device (including the pump body and inflation tubing) integrated into the same shell. This often results in a large overall size, taking up considerable storage space during outdoor activities and making them inconvenient to carry, especially in scenarios with limited backpack capacity or where gear needs to be streamlined. This causes numerous inconveniences for users. Because the various functional components are clustered in a closed shell, the structure is compact and interconnected. When the device malfunctions and requires repair or replacement of parts, multiple connecting structures must be disassembled to access the internal components, making the operation complex. This not only increases the difficulty of maintenance for users but may also cause secondary damage to the device due to improper disassembly. When the air pump is working, the operation of the inflation device's motor and the power supply process generate a lot of heat. In an integrated structure, the heat-generating components are close to each other, and the heat tends to accumulate inside, making it difficult to dissipate quickly. Over time, excessively high temperatures can affect the efficiency and lifespan of the components. Utility Model Content

[0004] The purpose of this invention is to provide a foldable outdoor air pump that is easy to store, convenient to maintain, and has low heat dissipation pressure. It solves the problems of large size, inconvenience to carry, difficult maintenance, and high heat dissipation pressure of existing air pumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A foldable and retractable outdoor air pump includes a load-bearing component, which includes a connecting box. Protective boxes two and one are hinged to the upper and lower ends of the connecting box, respectively. The hinge points of protective boxes two and one are both located on the right end of the connecting box. Protective boxes one and two are of the same height. Fixing components are installed at the front and rear ends of protective boxes one and two. Each fixing component includes a connecting sleeve one rotatably mounted at the center of the front and rear ends of protective box one. A connecting rod is fitted onto the inner wall of the connecting sleeve one. A sliding groove is formed through the outer wall of the connecting sleeve one. A push block is slidably mounted on the inner wall of the sliding groove and fixed to the outer wall of the connecting rod. The fixing component also includes a connecting sleeve two rotatably mounted at the center of the front and rear ends of protective box two. One end of the connecting rod is inserted into the inner wall of the connecting sleeve two. A driving component is installed within the load-bearing component. The driving component includes an inflation device fixed inside protective box one, an inflation tube installed inside the connecting box, and a battery fixed to the inner wall of protective box two.

[0006] Preferably, a handle is rotatably mounted at the center of the right end of the connecting box, and the load-bearing component also includes a base fixed to the ends of the protective boxes one and two that are far apart from each other.

[0007] It is worth noting that the handle can be rotated around the right end of the connecting box. The device can be folded and stored for easy lifting and carrying, improving its outdoor portability. When the device is unfolded (protective box one, protective box two and connecting box are in working state), the base can protect the bottom of the protective box from ground scratches and increase the friction with the ground, improving the stability during inflation and preventing the device from vibrating and shifting.

[0008] Preferably, both the first and second protective boxes are hinged with retaining rings on their left ends, and the left end of the connecting box is fixed with buckles distributed vertically, with the retaining rings and buckles being compatible.

[0009] It is worth noting that the retaining ring can cooperate with the buckle to connect and fix the left ends of the first protective box, the second protective box and the connecting box after folding the second protective box and the connecting box, ensuring the firmness of the protective box when closed and protecting the drive components.

[0010] Preferably, the fixing component further includes a threaded hole extending through the outer wall of the connecting sleeve, and a stud threaded into the threaded hole, the end of the stud abutting against the outer wall of the connecting rod.

[0011] It is worth noting that by rotating and tightening the stud, the end of the stud can be made to fit against the outer wall of the connecting rod, ensuring that one end of the connecting rod can be firmly fixed to the inner wall of the second connecting sleeve, thereby ensuring the stability of the connection between the first connecting sleeve and the second connecting sleeve, and thus ensuring the firmness of the protective box when it is unfolded or folded.

[0012] Preferably, the drive assembly further includes a rotating column fixed to the center of the inner wall of the upper end of the connecting box, a drum rotatably mounted on the outer wall of the rotating column, and an inflation tube wound on the outer wall of the drum.

[0013] It is worth noting that the rotating column can limit the position of the drum, and the drum can rewind the inflation tube, making it convenient to store and use the inflation tube.

[0014] Preferably, a protective cover is also hinged inside the upper opening of the connecting box, and the lower end of the protective cover fits against the upper end of the drum.

[0015] It is worth noting that the protective cover can limit and fix the roll, thereby ensuring the stability of the inflation tube after it is stored and protecting the inflation tube.

[0016] Preferably, the upper end of the inflation device is provided with a power socket and an air outlet. The power socket is compatible with the power supply plug of the battery, and the air outlet is compatible with the inflation tube. The inflation device consists of a motor, a cylinder and a controller.

[0017] It is worth noting that by inserting the battery power cord into the corresponding power socket, the battery can power the inflation device after the protective box is unfolded. Then, by connecting one end of the inflation tube to the air outlet, inflation can be easily performed. The controller can control the motor, thereby driving the cylinder to work and complete the inflation process.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes two protective boxes, one and two, which rotate around the right end of a connecting box via their respective hinges. In the unfolded state, they provide independent and stable housing spaces for the internally installed inflation device (inside the first protective box) and battery (inner wall of the second protective box), preventing components from squeezing each other. In the folded state, they can be brought closer to the connecting box, significantly reducing the overall volume of the device and making it easy to carry outdoors. At the same time, the connecting rod on the inner wall of the first connecting sleeve in the fixing assembly can have its extension length adjusted by a sliding push block in the groove, ensuring that one end of the connecting rod can be accurately inserted into the inner wall of the second connecting sleeve regardless of whether the first or second protective box is unfolded or folded. This initially achieves the connection and positioning of the three components, providing a foundation for subsequent reinforcement with other structures and ensuring the structural stability of the device in different states.

[0021] 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.

[0022] To address the problems of bulky, inconvenient to carry, difficult to maintain, and high heat dissipation pressure in existing air pumps, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-5 ; A foldable and retractable outdoor air pump includes a load-bearing assembly. The load-bearing assembly includes a connecting box 101. Protective boxes 102 and 103 are hinged to the upper and lower ends of the connecting box 101, respectively. The hinge points of protective boxes 103 and 102 are both located at the right end of the connecting box 101. Protective boxes 102 and 103 are of the same height. Fixing components are installed at the front and rear ends of protective boxes 102 and 103. The fixing components include a connecting sleeve 201 rotatably mounted at the center of the front and rear ends of protective box 102. A connecting rod 203 is fitted onto the inner wall of the connecting sleeve 201. A sliding groove 205 is provided through the outer wall of the connecting sleeve 1 201. A push block 204 is slidably provided on the inner wall of the sliding groove 205. The push block 204 is fixed to the outer wall of the connecting rod 203. The fixing component also includes a connecting sleeve 202 rotatably installed at the center of the front and rear ends of the protective box 2 103. One end of the connecting rod 203 is inserted into the inner wall of the connecting sleeve 202. A driving component is installed in the bearing component. The driving component includes an inflation device 301 fixed in the protective box 1 102. The driving component also includes an inflation pipe 306 installed in the connecting box 101 and a battery 307 fixed in the inner wall of the protective box 2 103.

[0023] The protective boxes 102 and 103 rotate around the right end of the connecting box 101 via their respective hinges. In the unfolded state, they provide independent and stable housing space for the internally installed inflation device 301 (inside the protective box 102) and battery 307 (inner wall of the protective box 103), preventing components from squeezing each other. In the folded state, they can move towards the connecting box 101, significantly reducing the overall volume of the device and making it easy to carry outdoors. At the same time, the connecting rod 203 on the inner wall of the connecting sleeve 201 in the fixing assembly can be adjusted in length by means of the push block 204 sliding in the slide groove 205. This ensures that one end of the connecting rod 203 can be accurately inserted into the inner wall of the connecting sleeve 202, whether the protective boxes 102 and 103 are unfolded or folded. This initially achieves the connection and positioning of the three, providing a foundation for subsequent reinforcement with other structures and ensuring the structural stability of the device in different states.

[0024] Please see Figure 3 A handle 105 is rotatably mounted on the center of the right end of the connecting box 101. The supporting component also includes a base 104 fixed to the ends of the protective box 102 and the protective box 2 103 that are far apart from each other. The handle 105 can rotate around the right end of the connecting box 101. After the device is folded and stored, it is easy to lift and carry, improving outdoor portability. After the device is unfolded (the protective box 102, the protective box 2 103 and the connecting box 101 are in working state), the base 104 can protect the lower end of the protective box from ground scratches and increase the friction with the ground, improve the stability during inflation, and prevent the device from vibrating and shifting.

[0025] Both the left ends of the first protective box 102 and the second protective box 103 are hinged with retaining rings 106, and the left end of the connecting box 101 is fixed with buckles 107 distributed vertically. The retaining rings 106 and buckles 107 are compatible. By engaging with the buckles 107 through the retaining rings 106, after folding the second protective box 103 and the connecting box 101, the left ends of the first protective box 102, the second protective box 103 and the connecting box 101 can be connected and fixed to each other to ensure the firmness of the protective boxes when closed and to protect the drive components.

[0026] Please see Figure 4 The fixing component also includes a screw hole 206 that penetrates the outer wall of the connecting sleeve 202, and a stud 207 threaded into the screw hole 206. The end of the stud 207 abuts against the outer wall of the connecting rod 203. By rotating and tightening the stud 207, the end of the stud 207 can fit against the outer wall of the connecting rod 203, ensuring that one end of the connecting rod 203 can be firmly fixed to the inner wall of the connecting sleeve 202, thereby ensuring the stability of the connection between the connecting sleeve 1 201 and the connecting sleeve 202, and thus ensuring the firmness of the protective box when it is unfolded or folded.

[0027] Please see Figure 5The drive assembly also includes a rotating column 304 fixed to the center of the inner wall of the upper end of the connecting box 101. A drum 305 is rotatably mounted on the outer wall of the rotating column 304, and an inflation tube 306 is wound up on the outer wall of the drum 305. The rotating column 304 can limit the position of the drum 305, and the drum 305 can wind up the inflation tube 306, which facilitates the storage and use of the inflation tube 306. A protective cover 108 is also hinged in the upper opening of the connecting box 101, and the lower end of the protective cover 108 is attached to the upper end of the drum 305. The protective cover 108 can limit and fix the drum 305, thereby ensuring the stability of the inflation tube 306 after storage and protecting the inflation tube 306.

[0028] The upper end of the inflation device 301 is provided with a power socket 302 and an air outlet 303. The power socket 302 is compatible with the power supply plug of the battery 307, and the air outlet 303 is compatible with the inflation tube 306. The inflation device 301 consists of a motor, a cylinder, and a controller. By inserting the power supply plug of the battery 307 into the corresponding power socket 302, the battery 307 can supply power to the inflation device 301 after the protective box is unfolded. By connecting one end of the inflation tube 306 to the air outlet 303, inflation can be easily performed. The controller can control the motor, thereby driving the cylinder to work and complete the inflation.

[0029] Working principle: First, disengage the retaining ring 106 at the left hinge of protective box 102 and protective box 2 103 from the buckle 107 at the left end of connecting box 101. Then, rotate protective box 102 and protective box 2 103 around the hinge at the right end of connecting box 101 until all three are stably unfolded. At this time, push the push block 204 in the sliding groove 205 on the outer wall of the connecting sleeve 1 201 at the front and rear ends of protective box 102, causing the connecting rod 203 to slide along the inner wall of the connecting sleeve 1 201. Move the connecting rod 203 so that one end is inserted into the inner wall of the connecting sleeve 202 at the front and rear ends of the protective box 2 103; then rotate the stud 207 in the screw hole 206 on the outer wall of the connecting sleeve 202 so that the end of the stud 207 presses against the outer wall of the connecting rod 203, thereby achieving a firm fixation between the connecting sleeve 1 201 and the connecting sleeve 202. At the same time, the base 104 at the opposite end of the protective box 1 102 and the protective box 2 103 is in contact with the ground to increase friction and prevent the device from vibrating and shifting during subsequent inflation. Insert the power cord plug of the battery 307 inside the second protective box 103 into the power socket 302 at the top of the inflation device 301 inside the first protective box 102 to power the inflation device 301; then open the protective cover 108 hinged at the top opening of the connecting box 101, rotate the drum 305 on the outer wall of the rotating column 304 around the inner wall of the upper end of the connecting box 101, pull out the inflation tube 306 wound on the drum 305, connect one end of the inflation tube 306 to the air outlet 303 at the top of the inflation device 301, and connect the other end to the outdoor equipment to be inflated.

[0030] The controller built into the inflation device 301 controls the internal motor, which drives the cylinder to generate airflow. The airflow passes through the air outlet 303 and the inflation pipe 306 of the inflation device 301 and enters the outdoor equipment to be inflated, completing the inflation operation. During the inflation process, the base 104 continuously ensures the stability of the device. The first protective box 102 and the second protective box 103 provide independent protective spaces for the inflation device 301 and the battery 307, respectively, to prevent the components from being interfered with by the outside world. After inflation, first turn off the inflation device 301 through the controller, disconnect the inflation tube 306 from the air outlet 303 and the outdoor equipment, rewind the inflation tube 306 onto the reel 305, and cover it with the protective cover 108 to limit and protect the inflation tube 306; then unplug the battery 307 power supply plug from the power socket 302, loosen the stud 207, and pull the connecting rod 203 out of the connecting sleeve 202; finally, around the right hinge of the connecting box 101, fold the protective box 102 and the protective box 203 toward the connecting box 101, and lock the left end of the three by inserting the retaining ring 106 into the buckle 107. At this time, the handle 105 installed on the right end of the connecting box 101 can be rotated to lift the device, and the portable storage can be completed.
