Description

Technical Field

[0001] This utility model belongs to the field of multi-functional air pump technology, specifically relating to a multi-functional air pump that integrates direct charging and burst charging. Background Technology

[0002] An air pump is an air pump that draws air into a cylinder by pulling up and down the inner rod. Air is then injected into or replenished to various tires and some balls by pushing it forward. There are many air pumps on the market, including direct-pump and burst-charge types. However, they are limited in function and can only inflate tires of a specific type. For example, direct-pump pumps often fail to inflate tubeless tires due to insufficient air pressure and volume. Burst-charge pumps, on the other hand, store a certain amount of gas in a tank and then inject it continuously into the tubeless tire through a valve, quickly inflating it. However, a significant problem exists: each inflation requires filling the tank first, and the pressure must be greater than that of the object being inflated. This is analogous to a communicating vessel; only the portion of air exceeding the pressure of the object can enter, resulting in a significant waste of time and effort. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a multi-functional air pump that integrates direct charging and burst charging. It can freely switch between three modes: direct charging, accumulating pressure, and burst charging. Different modes can be used according to the environmental needs of the object being charged. In addition, the air pressure gauge can automatically switch and read the air pressure value of the current mode through the air pressure valve, thereby reducing unnecessary time and effort and greatly improving the efficiency and convenience of use.

[0004] The technical solution adopted by this utility model is a direct-charge and high-explosive integrated multi-functional air pump, including a base, on which an air pump and an air tank are arranged horizontally side by side. A shift valve is coaxially inserted through the base and the air tank. A pressure gauge is connected to the top of the air tank and the top of the air pump. A handle is connected to the top of the pressure gauge. Foot pedals are connected to both sides of the bottom of the base through foot pedal connecting shafts.

[0005] The present invention is further characterized in that,

[0006] The air pump has an inner piston rod inside, and the bottom end of the inner piston rod is connected to a piston and a piston sealing ring in sequence. The top end of the inner piston rod passes through the pressure gauge and is connected to the handle.

[0007] The gas storage tank is equipped with a connecting hose, the bottom end of which is connected to the base, and the top end of which is connected to the pressure gauge.

[0008] The shift valve includes a shift valve body, a valve seal is connected to the left side of the shift valve body, and a shift valve fixing cover is connected to the left side of the valve seal.

[0018] 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. Example 1:

[0019] like Figure 1-4 As shown, this utility model discloses a direct-charge and high-pressure integrated multi-functional air pump, including a base 1. The base 1 is made of high-strength metal or composite material and is used to support the air pump 2 and the air tank 3 as a whole, ensuring stability under high-pressure working conditions. The air pump 2 and the air tank 3 are horizontally and fixedly installed side by side on the base 1. A shift valve 4 is coaxially inserted between the base 1 and the air tank 3. The shift valve 4 is a rotary switching structure, which can select the direct-charge mode or the high-pressure mode according to the usage requirements. The top of the air tank 3 and the air pump 2 are connected to a pressure gauge 5, which is used to display the pressure of the air tank 3 or the air pump 2 in real time. The internal air pressure status allows users to monitor the pressure at any time during inflation, avoiding over-inflation or under-inflation. A handle 6 is installed at the top of the pressure gauge 5. The handle 6 adopts an ergonomic design, making it easy for users to lift or move the entire device during operation, enhancing portability and practicality. The bottom ends of the base 1 are connected to foot pedals 8 on both sides via foot pedal connecting shafts 7, forming a stable support operating platform. When the user steps on the foot pedals 8, it can effectively enhance the stability of the air pump, preventing the device from shaking or tipping over during high-pressure operation, facilitating the storage and carrying of the device, thus achieving a balance between compact structure and convenient operation.

[0020] The air pump 2 has an internal piston rod 201, which is a longitudinally penetrating cylindrical metal rod. The bottom end of the piston rod 201 is sequentially connected to a piston 202 and a piston sealing ring 203. The piston 202 adopts an integral disc structure, and its diameter is tightly fitted with the inner wall of the air pump 2. It is used to push the gas to compress and transport in the cavity. The piston 202 is equipped with a piston sealing ring 203. The sealing ring 203 can tightly fit the inner wall of the air pump 2 during the reciprocating motion of the piston 202, preventing the compressed gas from leaking under high pressure, thereby improving the airflow compression efficiency and extending the service life of the air pump 2.

[0021] The top end of the piston inner rod 201 passes through the lower end structure of the pressure gauge 5 and is fixedly connected to the handle 6. The handle 6 serves as an operating component and is rigidly fixedly connected to the piston inner rod 201, so that when the user pushes or pulls the handle 6, the piston inner rod 201 can be directly driven to move up and down reciprocally, thereby realizing the function of air intake and compression discharge inside the air pump 2.

[0022] The gas storage tank 3 is equipped with a connecting hose 301 inside. The connecting hose 301 is a flexible pressure-resistant pipe used to achieve a sealed connection and air pressure transmission between the gas storage tank 3 and the pressure gauge 5. The bottom end of the connecting hose 301 is connected to the base 1 through a fastening connector. The base 1 has a gas channel that communicates with the air pump 2, so that compressed air can smoothly enter the interior of the connecting hose 301 through the base 1 during the air pumping process. The top end of the connecting hose 301 is connected to the pressure gauge 5 through a connector to ensure that a stable and reliable sealing state can be maintained under high pressure, avoiding reading deviation or energy loss due to gas leakage.

[0023] The shift valve 4 specifically includes a shift valve body 401. The shift valve body 401 is provided with a channel switching mechanism inside, which is used to switch the airflow channel between the direct charging mode and the burst charging mode. A valve seal 402 is connected to the left side of the shift valve body 401. The valve seal 402 is installed at the valve connection. A shift valve fixing cover 403 is further connected to the left side of the valve seal 402. The fixing cover 403 is tightly connected to the valve body 401 by threads.

[0024] The pressure gauge 5 specifically includes a pressure gauge housing 501. The interior of the pressure gauge housing 501 is divided into a connected left cavity 502 and a right cavity 503. The two cavities are interconnected through a middle channel to form a functional path for pressure transmission and detection. A piston rod 201 is sleeved inside the left cavity 502. A pressure gauge valve 504 is installed inside the right cavity 503. The top of the pressure gauge valve 504 is connected to the pressure gauge body 505. The pressure gauge body 505 is used to display the real-time air pressure value in the air tank 3 or the air pump 2, which can provide the operator with an intuitive pressure reference and avoid affecting the safety and effectiveness of use due to excessive or insufficient pressure. A fixing cover 506 is provided at the top of the right cavity 503. The fixing cover 506 is made of high-strength transparent material and is fastened to the upper end of the pressure gauge housing 501. It not only protects the interior but also prevents external dust, moisture or impurities from entering, thus extending the service life of the pressure gauge 5.

[0025] The pressure gauge valve 504 specifically includes a pressure gauge valve body 507. A rubber ball 508 is provided in the inner cavity of the pressure gauge valve body 507. The rubber ball 508 is used to switch the airflow path. A valve plug 509 is connected to one side of the pressure gauge valve body 507. The valve plug 509 is reliably connected to the pressure gauge valve body 507 through a snap-fit ​​structure. The plug 509 plays a role in sealing and fixing.

[0026] Working principle: During inflation, gas enters different positions through the shift valve 4. Rotating the shift valve 4 clockwise once activates direct inflation, twice activates the accumulator mode, and a third time activates the burst inflation mode. In direct inflation mode, the rubber ball 508 moves to the right, blocking the passage to the air tank 3, preventing reverse air from flowing into the air tank 3. At this time, a small amount of gas enters the pressure gauge through the connecting hose 301, thus enabling the pressure reading. When using the accumulator mode, the rubber ball 508 moves to the left, sealing the passage to the outside, thus enabling the air tank 3 to accumulate pressure and read the pressure. When using the burst inflation mode, the gas in the air tank 3 flows to the outside through the shift valve 4 on the base, and the pressure gauge 5 can still read the pressure. This achieves three inflation modes, and the pressure data can be read in all three modes.
