[0040] In one embodiment, the reference specification Figure 1 , Figure 2The utility model provides a multi-pump core inflation device, comprising: a seat body 1, a first high-pressure pump core member 2, a second high-pressure pump core member 3 and a low-pressure pump core member 4, the seat body 1 is provided with a first interface 11, a second interface 12, a third interface 14, an air outlet 13 and an air flow cavity connected between the first interface 11, the second interface 12, the third interface 14 and the air outlet 13; the first high-pressure pump core member 2 is provided with a first joint 21, and the first joint 21 is adapted to be connected with the first interface 11; the second high-pressure pump core member 3 is provided with a second joint 31, and the second joint 31 is adapted to be connected with the second interface 12; the low-pressure pump core member 4 is provided with a third joint 41 and an air inlet 42, and the third joint 41 is adapted to be connected with the third interface 14, so that the air inlet 42 is connected with the third interface 14; starting the first high-pressure pump core member 2 and / or the second high-pressure pump core member 3 can adjust the air pressure in the air flow cavity.

[0041] Exemplarily, the low-pressure pump core 4 is a low-pressure pump, the first high-pressure pump core 2 and the second high-pressure pump core 3 are both high-pressure pumps, and the two are arranged in parallel. The first high-pressure pump core 2 and / or the second high-pressure pump core 3 can pressurize the gas to a pressure of 20psI units; the low-pressure pump core 4 can pressurize the flow to 280L / min. It can be applied to high-pressure inflation scenarios, and can effectively improve the inflation efficiency compared to a single pump core device; for example, to inflate a tire, a large-flow low-pressure pump is first needed to quickly fill the tire, and when pressurization is required after it is filled, a small-flow high-pressure pump is used for pressurization, which can effectively improve the inflation efficiency compared to a single pump core device.

[0042] In the utility model, rapid inflation is performed through the low-pressure pump core component 4, and rapid pressurization is performed by the first high-pressure pump core component 2 and the second high-pressure pump core component 3, which significantly improves the inflation speed, greatly shortens the inflation time, and improves work efficiency; and the multi-pump core inflation device can balance the inflation pressure, ensure stability and uniformity during the inflation process, and improve the inflation quality; in addition, the multi-pump core inflation device has high reliability and stability. Even if one of the pump core components fails, the other pump core components can still work normally and will not affect the operation of the entire inflation system; it is also beneficial to energy saving and environmental protection, and the number of pump cores can be adjusted according to needs to avoid unnecessary energy waste; the multi-pump core inflation device has strong adaptability, and the appropriate number and specifications of pump cores can be selected according to the requirements of different inflation objects, and combined in parallel or series to meet the needs of various inflation scenarios.

[0043] It should be noted that the first high-pressure pump core component 2, the second high-pressure pump core component 3 and the low-pressure pump core component 4 can all be finished air pumps, which can be purchased products or customized products, and can be set according to actual needs; the first high-pressure pump core component 2 and the second high-pressure pump core component 3 can be set to at least one number respectively. The first high-pressure pump core component 2, the second high-pressure pump core component 3 and the low-pressure pump core component 4 are set in series, parallel or series-parallel according to actual needs. The number of pump core components can also be set to more, such as four, five, six, etc.

[0044] Specifically, the first interface 11 and the second interface 12 are arranged on the same side of the seat body 1, and the first high-pressure pump core member 2 and the second high-pressure pump core member 3 are detachably connected to the seat body 1. Among them, a first flange is arranged at the first interface 11, and the first flange is detachably connected to the first joint 21 of the first high-pressure pump core member 2 by bolts; a second flange is arranged at the second interface 12, and the second flange is detachably connected to the second joint 31 of the second high-pressure pump core member 3 by bolts. Since the first high-pressure pump core member 2 and the second high-pressure pump core member 3 are high-pressure pumps, the connection between the first high-pressure pump core member 2, the second high-pressure pump core member 3 and the seat body 1 needs to withstand a higher pressure, so it is set to a flange connection mode, which can improve the structural stability; of course, it can also be set to other connection modes, such as clamping, threaded connection, etc.

[0045] The third interface 14 is arranged on the side of the seat body 1 and is located on the side adjacent to the first interface 11 and the second interface 12; the air outlet 13 is arranged on the side of the seat body 1 and is located on the side opposite to the first interface 11 and the second interface 12. Of course, the air outlet 13 can also be arranged on the side adjacent to the first interface 11 and the second interface 12. The end of the seat body 1 is also provided with an air outlet 15, and a detachably connected cover body 15 is arranged at the air outlet 15. The air outlet 15 can be used as a spare interface. When more pump core parts need to be connected, the cover body 15 can be removed and the required pump core parts can be installed. When more pump core parts are not needed, the air outlet 15 can be closed with the cover body 15.

[0046] In the present embodiment, a scheme of connecting multiple pump cores in parallel is adopted, so that different pump cores can work together at the same time, which solves the performance deficiency of a single pump core and enables the product to significantly improve its performance at a certain cost; the present device can be inflated quickly, and through the simultaneous operation of multiple pump cores, the inflation speed is faster, saving time and effort; the multi-pump core system can balance the inflation pressure, it can maintain the stability and uniformity of inflation, and the inflation quality is higher; in addition, the multi-pump core system has high reliability and stability. Even if one of the pump cores fails, the other pump cores can still work normally without affecting the operation of the entire inflation system, thus ensuring the reliability of the system.

[0047] The multi-pump core inflation device is also beneficial to energy conservation and environmental protection. The number of pump cores can be adjusted according to needs to avoid unnecessary energy waste. The multi-pump core inflation device has strong adaptability and can select the appropriate number and specifications of pump cores according to the requirements of different inflation objects, and combine them in parallel or series to meet the needs of various inflation scenarios.

[0048] In one embodiment, the reference specification Figure 1 , Figure 2 The multi-pump core inflation device further includes: a one-way valve assembly 5, which is detachably installed between the third interface 14 and the third joint 41. Since the first high-pressure pump core component 2 and the second high-pressure pump core component 3 are high-pressure pumps, and the low-pressure pump core component 4 is a low-pressure pump, by arranging the one-way valve assembly 5 between the third interface 14 and the third joint 41, it is possible to effectively prevent the high-pressure gas in the seat body 1 from flowing back into the low-pressure pump core component 4.

[0049] Specifically, a third flange is provided at the third interface 14, and the one-way valve assembly 5 includes an O-ring 51, a one-way valve 52, a support 53 and a silicone pad 54. The one-way valve 52 is provided on the support 53, and the support 53 is detachably connected to the third flange by bolts, and the O-ring 51 is clamped between the third flange and the support 53; a rotating slot 531 is provided at one end of the support 53 away from the seat body 1, and a clamping block 411 is provided at the third joint 41, and the clamping block 411 is adapted to be connected with the rotating slot 531, so that the low-pressure pump core member 4 is detachably connected to the support 53, and the silicone pad 54 is clamped between the support 53 and the low-pressure pump core member 4. Since the low-pressure pump core member 4 is a low-pressure pump, the pressure at the connection between the low-pressure pump core member 4 and the support 53 is not large. By realizing the detachable connection between the low-pressure pump core member 4 and the support 53 in a clamping manner, the loading and unloading efficiency can be effectively improved. Of course, it can also be set to other connection methods, such as bolt connection, threaded connection, etc.

[0050] Furthermore, the multi-pump core inflation device also includes: a switch and an air pressure sensor, the switch is connected to the low-pressure pump core component 4, and is used to start the low-pressure pump core component 4; the air pressure sensor is respectively connected to the first high-pressure pump core component 2 and the second high-pressure pump core component 3, when the air pressure sensor detects that the air pressure in the airflow chamber reaches a preset value, the first high-pressure pump core component 2 and / or the second high-pressure pump core component 3 is started.

[0051] In this embodiment, the specific installation process of the multi-pump core inflation device is as follows: place the sealing ring 161 in the groove on the cover 15, then fit the cover 15 on the air outlet 15, and use screws to fix the cover 15 and the base 11, and shake the cover 15 to ensure that the screws are not loose. According to the above steps, fix the first high-pressure pump core 2 at the first interface 11, and fix the second high-pressure pump core 3 at the second interface 12.

[0052] Place the O-ring 51 on the groove at the third joint 41, then install the one-way valve 52 into the support 53 according to its shape, then install the support 53 into the third joint 41 according to its shape, and finally fix the seat body 1 and the support 53 with screws; fit the silicone pad 54 into the support 53, fit the low-pressure pump core component 4 into the support 53, and finally rotate the low-pressure pump core component 4 so that the block 411 fits and engages with the rotating slot 531, thereby realizing the assembly of the multi-pump core inflation device.

[0053] In this embodiment, different pump cores can work together at the same time, which solves the performance deficiencies of a single pump core and enables the product to significantly improve performance at a certain cost. At the same time, the multi-pump core inflation device is also an efficient, reliable, energy-saving and environmentally friendly inflation solution, which can improve production efficiency, improve work quality, and is suitable for various inflation application fields.

[0054] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model.
