Description

Technical Field

[0001] This utility model relates to the field of air pumps, and in particular to a fast high-pressure air pump. Background Technology

[0002] An air pump is a device used to inflate inflatable products (such as air mattresses, inflatable paddleboards, inflatable tents, inflatable pools, etc.). However, many existing air pumps use high-flow-rate inflators, which inflate products using centrifugal fans. But because the internal pressure of an inflatable product changes before and after inflation, the pressure increases with each inflator, and the inflating efficiency of the high-flow-rate inflator decreases. Therefore, for inflatable products requiring higher internal pressure, the high-flow-rate inflator cannot quickly inflate them to the required pressure, resulting in a limitation in its use.

[0003] In view of the above problems, it is necessary to study a fast high-pressure air pump that can quickly inflate inflatable products that require high internal pressure to the required pressure. Utility Model Content

[0004] The purpose of this invention is to provide a fast high-pressure air pump that can quickly inflate products that require high internal pressure to the required pressure.

[0005] To achieve the above objectives, the solution of this utility model is:

[0008] The main air outlet chamber is equipped with an air inlet, which is connected to the air outlet end of the high-flow inflation mechanism. The air inlet is fitted with a high-flow one-way valve, which controls the gas to flow unidirectionally from the air outlet end of the high-flow inflation mechanism into the main air outlet chamber.

[0009] The high-flow inflation mechanism includes a high-flow inflation base and a centrifugal fan installed in the high-flow inflation base. The high-flow inflation base has a high-flow air inlet and a high-flow air outlet. The high-flow air outlet is connected to the main air outlet chamber. The air inlet and outlet of the centrifugal fan are respectively connected to the high-flow air inlet and the high-flow air outlet. The centrifugal fan is electrically connected to the control circuit board.

[0010] The high-flow-rate inflator is fitted with a filter that covers the high-flow-rate air inlet.

[0011] The inflation assembly has a connecting seat, which is connected to the high-pressure inflation core and forms the main air outlet chamber between the connecting seat and the high-pressure inflation core. The connecting seat is provided with the main air outlet interface.

[0012] The high-pressure inflation mechanism includes a high-pressure inflation seat, a piston, and a drive motor. The high-pressure inflation seat has a high-pressure air inlet and a high-pressure air outlet, with the high-pressure air outlet communicating with the main air outlet chamber. The piston is movably fitted within the high-pressure inflation seat, and the piston divides the inner cavity of the high-pressure inflation seat into an air inlet chamber communicating with the high-pressure air inlet and an air outlet chamber communicating with the high-pressure air outlet. The piston is provided with an air inlet hole connecting the air inlet chamber and the air outlet chamber. The piston is equipped with an air inlet check valve that controls the one-way flow of gas from the air inlet chamber into the air outlet chamber. The high-pressure air outlet is equipped with an air outlet check valve that controls the one-way flow of gas from the air outlet chamber into the main air outlet chamber. The drive motor is driven by the piston and drives the piston to reciprocate within the high-pressure inflation seat.

[0013] The drive motor is driven by the piston through an eccentric cam and an eccentric shaft. The drive motor drives the eccentric cam to rotate. One end of the eccentric shaft is connected to the eccentric cam, and the other end of the eccentric shaft is moved and engaged with the piston through an eccentric bearing.

[0014] The drive motor is connected to a cooling fan.

[0015] The high-pressure air inlet is equipped with sound-absorbing cotton.

[0016] The rapid high-pressure air pump also includes a power supply battery installed in the housing, which is electrically connected to the control circuit board.

[0017] The rapid high-pressure air pump also includes a charging interface mounted on the housing, which is electrically connected to the control circuit board.

[0021] The outer casing is equipped with a handle.

[0022] With the above solution, when the rapid high-pressure air pump of this utility model inflates an inflatable product, the control circuit board first controls the high-flow inflator mechanism to work, so that the high-flow inflator mechanism inflates the inflatable product through the main air outlet chamber and the main air outlet port. At the same time, the pressure sensor of the control circuit board detects the internal pressure of the main air outlet chamber. When the internal pressure of the main air outlet chamber reaches the set switching pressure, the control circuit board controls the high-flow inflator mechanism to stop working. At the same time, the control circuit board controls the high-pressure inflator mechanism to work, so that the high-pressure inflator mechanism inflates the inflatable product through the main air outlet chamber and the main air outlet port. At the same time, the pressure sensor of the control circuit board detects the internal pressure of the main air outlet chamber. When the internal pressure of the main air outlet chamber reaches the set inflation pressure, the control circuit board controls the high-pressure inflator mechanism to stop working, thus completing the inflation of the inflatable product.

[0023] As described above, the rapid high-pressure inflation of this invention inflates inflatable products by first using a high-flow inflation mechanism and then using a high-pressure inflation mechanism. The high-flow inflation mechanism is characterized by its large inflation flow rate, which can quickly increase the gas volume of the inflatable product. The high-pressure inflation mechanism has the advantage of high inflation pressure, which can ensure that inflation can continue even when the internal pressure of the inflatable product is high. Thus, this invention can first inflate the inflatable product with a large flow rate and then with high-pressure inflation, thereby quickly inflating inflatable products that require higher internal pressure to the required pressure.

[0050] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0051] like Figures 1 to 11 As shown, this utility model discloses a rapid high-pressure air pump, which includes a housing 1, a control circuit board 2 and an air inflation assembly 3 installed in the housing 1; wherein, the air inflation assembly 3 has a high-flow air inflation core 31, a high-pressure air inflation core 32, a main air outlet chamber 30 and a main air outlet port 331; the air outlet ends of the high-flow air inflation core 31 and the high-pressure air inflation core 32 are connected to the main air outlet chamber 30, and the main air outlet port 331 is connected to the main air outlet chamber 30 and can extend out of the housing 1; the control circuit board 2 is electrically connected to the high-flow air inflation core 31 and the high-pressure air inflation core 32 respectively, and the control circuit board 2 is provided with a pressure sensor 21 for detecting the internal pressure of the main air outlet chamber 30.

[0052] When inflating an inflatable product, the rapid high-pressure air pump of this invention first controls the high-flow-rate air pump 31 to operate, causing the high-flow-rate air pump 31 to inflate the product through the main air outlet chamber 30 and the main air outlet port 331. Simultaneously, the pressure sensor 21 of the control circuit board 2 detects the internal pressure of the main air outlet chamber 30. When the internal pressure of the main air outlet chamber 30 reaches the set switching pressure, the control circuit board 2 controls the high-flow-rate air pump 31 to stop operating. At the same time, the control circuit board 2 controls the high-pressure air pump 32 to operate, causing the high-pressure air pump 32 to inflate the product through the main air outlet chamber 30 and the main air outlet port 331. Simultaneously, the pressure sensor 21 of the control circuit board 2 detects the internal pressure of the main air outlet chamber 30. When the internal pressure of the main air outlet chamber 30 reaches the set inflation pressure, the control circuit board 2 controls the high-pressure air pump 32 to stop operating, completing the inflation of the inflatable product. As described above, when inflating an inflatable product, the rapid high-pressure inflation of this invention first uses a high-flow inflation mechanism 31 for inflation, and then uses a high-pressure inflation mechanism 32 for inflation. The high-flow inflation mechanism 31 has the characteristic of a large inflation flow rate, which can quickly increase the gas volume of the inflatable product. The high-pressure inflation mechanism 32 has the advantage of a large inflation pressure, which can ensure that inflation can continue even when the internal pressure of the inflatable product is high. In this way, this invention can first inflate the inflatable product with a large flow rate and then perform high-pressure inflation, thereby quickly inflating the inflatable product to the required pressure for products that require higher internal pressure.

[0053] In an embodiment of this invention, the control circuit board 2 is provided with a button assembly 22 having multiple buttons. The outer shell 1 is provided with button clearance holes 11 corresponding to the button assembly 22, and the outer shell 1 is fitted with button stickers 12 that cover each button clearance hole 11. The user can issue commands to the control circuit board 2 through the button assembly 22 to control whether the rapid high-pressure air pump of this invention works and to set the inflation pressure and conversion pressure for the inflatable product. It should be noted that this invention can preset multiple inflation modes for different inflatable products (such as inflatable mattresses, inflatable paddleboards, inflatable tents, and inflatable pools). Each inflation mode corresponds to a set inflation pressure, and the user selects different inflation modes through the button assembly 22.

[0054] In an embodiment of this utility model, the control circuit board 2 is provided with a display device 23, and the outer shell 1 is provided with a display window 13 corresponding to the display device. The display window 13 is equipped with a light-transmitting protective film 14 to protect the display device 23. The light-transmitting protective film 14 can be integrated with the button sticker 12. The display device 23 can be used to display the current inflation pressure, various inflation modes and whether the inflation mode is selected, the current air pressure unit, etc.

[0055] In an embodiment of this utility model, the main air outlet chamber 30 may be provided with an air inlet connection port 301, which is connected to the air outlet end of the high-flow inflation mechanism 31. The air inlet connection port 301 is equipped with a high-flow one-way valve 3011, which controls the gas to flow unidirectionally from the air outlet end of the high-flow inflation mechanism 31 into the main air outlet chamber 30. In this way, when the high-pressure inflation mechanism 32 is working, the gas output by the high-pressure inflation mechanism 32 will not flow into the high-flow inflation mechanism 31 and affect the high-flow inflation mechanism 31.

[0056] In an embodiment of this utility model, the inflation component 3 may have a connecting seat 33, which is connected to the high-pressure inflation core 32 and forms the total air outlet chamber 30 between the connecting seat 33 and the high-pressure inflation core 32. The connecting seat 33 is provided with the total air outlet interface 331.

[0057] In an embodiment of this utility model, the high-flow-rate inflation mechanism 31 may include a high-flow-rate inflation base 311 and a centrifugal fan 312 disposed within the high-flow-rate inflation base 311; the high-flow-rate inflation base 311 may be composed of at least two components to accommodate the centrifugal fan 312; the high-flow-rate inflation base 311 has a high-flow-rate air inlet 3111 and a high-flow-rate air outlet 3112, the high-flow-rate air outlet 3112 being connected to the air inlet connection port 301 to achieve communication with the main air outlet chamber 30, and a cover for the high-flow-rate air inlet may be fitted inside the high-flow-rate inflation base 311. The filter element 313 of 3111 prevents foreign objects from entering the high-flow air filling seat 311 and damaging the centrifugal fan 312. The filter element 313 can be made of sponge, which has the functions of filtering and sound absorption and can reduce noise. The air inlet and outlet of the centrifugal fan 312 are connected to the high-flow air inlet 3111 and the high-flow air outlet 3112 respectively. The centrifugal fan 312 is electrically connected to the control circuit board 2. When the centrifugal fan 312 is working, the centrifugal fan 312 draws in external air from the high-flow air inlet 3111 and outputs it from the high-flow air outlet 3112.

[0058] In an embodiment of this utility model, the high-pressure inflation mechanism 32 can adopt a piston 322 type air pump structure; specifically, the high-pressure inflation mechanism 32 may include a high-pressure inflation base 321, a piston 322, and a drive motor 323. The high-pressure inflation base 321 can be composed of at least two components to install the piston 322; the high-pressure inflation base 321 is connected to the connecting seat 33, and the two form a total air outlet chamber 30. An air inlet 301 can be provided on the high-pressure inflation base 321. The high-pressure inflation base 321 has a high-pressure air inlet 3211 and a high-pressure air outlet 3212. 212 is connected to the main exhaust chamber 30. The high-pressure air inlet 3211 can be fitted with sound-absorbing cotton 327, which serves to absorb sound and filter foreign objects. The piston 322 is movably fitted inside the high-pressure air filling seat 321, and the piston 322 divides the inner cavity of the high-pressure air filling seat 321 into an air inlet chamber 3214 communicating with the high-pressure air inlet 3211 and an air outlet chamber 3215 communicating with the high-pressure air outlet 3212. The piston 322 is provided with an air inlet hole 3221 connecting the air inlet chamber 3214 and the air outlet chamber 3215. The piston 322 is equipped with a control device to control the unidirectional flow of gas from the air inlet chamber 3214. An inlet check valve 3222 is provided in the inlet / outlet chamber 3215. A high-pressure outlet 3212 is equipped with an outlet check valve 3213 that controls the unidirectional flow of gas from the outlet chamber 3215 into the main outlet chamber 30. An inner liner 328, which is in a sealing fit with the piston 322, can be fitted inside the high-pressure inflation seat 321, allowing the piston 322 to move smoothly. A drive motor 323 is driven by the piston 322, driving the piston 322 to reciprocate within the high-pressure inflation seat 321, thus inflating the high-pressure inflation mechanism 32. Specifically, when the piston 322 moves towards the high-pressure inlet... When the piston moves in the direction of 3211, the volume of the intake chamber 3214 decreases and the volume of the outlet chamber 3215 increases. At this time, the intake check valve 3222 opens and the outlet check valve 3213 closes, and external gas is input into the outlet chamber 3215 through the intake chamber 3214. When the piston 322 moves towards the high-pressure outlet 3212, the volume of the intake chamber 3214 increases and the volume of the outlet chamber 3215 decreases. At this time, the intake check valve 3222 closes and the outlet check valve 3213 opens, and the gas in the outlet chamber 3215 is output from the high-pressure outlet 3212 to the main outlet chamber 30.

[0059] In this embodiment of the invention, the drive motor 323 is driven by the piston 322 via the eccentric cam 325 and the eccentric shaft 326. The drive motor 323 drives the eccentric cam 325 to rotate. The drive motor 323 is also connected to the eccentric cam 325 via a gear transmission mechanism. One end of the eccentric shaft 326 is connected to the eccentric cam 325, and the other end of the eccentric shaft 326 is movably connected to the piston 322 via the eccentric bearing 327. When the drive motor 323 drives the eccentric cam 325 to rotate continuously in one direction, the eccentric cam 325 drives the piston 322 to reciprocate via the eccentric shaft 326 and the eccentric bearing 327, thereby causing the high-pressure inflation mechanism 32 to inflate. Furthermore, the drive motor 323 can be connected to a cooling fan 329. When the high-pressure inflation mechanism 32 is working, the cooling fan 329 rotates to dissipate heat. The outer casing 1 can be provided with corresponding heat dissipation holes 17.

[0060] In embodiments of this invention, the rapid high-pressure air pump may further include a detection hose 4 installed in the housing 1. One end of the detection hose 4 is connected to the main air outlet chamber 30, and the other end of the detection hose 4 is engaged with the detection end of the pressure sensor 21. Through the detection hose 4, the internal pressure of the main air outlet chamber 30 can act on the pressure sensor 21, allowing the pressure sensor 21 to detect the internal pressure of the main air outlet chamber 30. When the rapid high-pressure air pump inflates the product, the internal pressure of the main air outlet chamber 30 is equivalent to the internal pressure of the product. Furthermore, due to the deformable nature of the detection hose 4, the inflation assembly 3 and the control assembly can be easily arranged within the housing 1, improving design flexibility.

[0061] In embodiments of this invention, the rapid high-pressure air pump may further include a power supply battery 5 installed in the housing 1. The power supply battery 5 is electrically connected to the control circuit board 2, and can provide the power required for the rapid high-pressure air pump to operate. Furthermore, the rapid high-pressure air pump may also include a charging interface 6 installed in the housing 1. The charging interface 6 is electrically connected to the control circuit board 2 and is used to connect to an external power source, allowing the external power source to charge the power supply battery 5. Additionally, this invention can also directly provide the power required for operation via an external power source.

[0062] In an embodiment of this utility model, the rapid high-pressure air pump of this utility model may further include a lamp plate 7 installed in the housing 1, the lamp plate 7 being electrically connected to the control circuit board 2, and the housing 1 having a lamp cover 15 corresponding to the lamp plate 7; this arrangement enables the rapid high-pressure air pump of this utility model to provide lighting function.

[0063] In an embodiment of this utility model, the outer shell 1 may be composed of at least two parts, which facilitates the use of other devices of this utility model; the outer shell 1 may be provided with a handle 16 so that the user can take the fast high-pressure air pump of this utility model.

[0064] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
