[0008] A low-pressure blowing and suction assembly is partially disposed within the receiving portion, and the low-pressure blowing and suction assembly is positioned above the high-pressure inflation assembly in the height direction of the receiving portion. The orthographic projection of the low-pressure blowing and suction assembly on the side portion in the width direction of the receiving portion partially coincides with the orthographic projection of the high-pressure inflation assembly on the side portion in the width direction of the receiving portion.

[0012] In one specific embodiment, the housing further includes:

[0013] The first receiving section is located on the side of the receiving section away from the high-pressure inflation assembly;

[0014] A first cover plate is disposed on the side of the first storage portion away from the receiving portion, and the first cover plate is hinged to the first storage portion.

[0015] In one specific embodiment, the high and low pressure air pump further includes a low pressure hose and at least three low pressure accessories, all of which are detachably disposed within a first receiving portion.

[0024] Beneficial effects

[0025] The high-low pressure air pump proposed in this application is not only compact in layout and small in size, but also achieves this by arranging the low-pressure blowing and suction components and the high-pressure inflation components vertically along the height of the receiving part. Furthermore, the orthographic projection of the low-pressure blowing and suction components on the side of the receiving part in the width direction coincides with the orthographic projection of the high-pressure inflation components on the side of the receiving part in the width direction.

At the same time, this design also ensures that the center of gravity of the entire high-low pressure air pump is centered, preventing any shift in the center of gravity and improving the stability of the low-pressure air pump during operation.

[0036] This application discloses a high-low pressure air pump, which includes a housing, a high-pressure inflation assembly, and a low-pressure blowing / suction assembly. The housing has a receiving portion. The high-pressure inflation assembly is disposed within the receiving portion, and the low-pressure blowing / suction assembly is partially disposed within the receiving portion. The low-pressure blowing / suction assembly is positioned above the high-pressure inflation assembly in the height direction of the receiving portion, and the orthographic projection of the low-pressure blowing / suction assembly onto the side portion in the width direction of the receiving portion coincides with the orthographic projection of the high-pressure inflation assembly onto the side portion in the width direction of the receiving portion. In this embodiment, the high-low pressure air pump optimizes the structure of the low-pressure blowing / suction assembly and the high-pressure inflation assembly, such as arranging them vertically along the height direction of the receiving portion. This ensures that the center of gravity of the high-low pressure air pump is centered, preventing center of gravity shift and improving the stability of the low-pressure air pump during operation.

[0037] Next, combine Figures 1-5 This application describes a high-low pressure air pump provided in an embodiment. The high-low pressure air pump has a compact layout and small size, improving its operational stability.

[0038] The high-low pressure air pump includes a housing 10, a high-pressure inflation assembly 20, and a low-pressure blowing and suction assembly 30. The housing 10 has a receiving portion 11. The high-pressure inflation assembly 20 is disposed in the receiving portion 11, and the low-pressure blowing and suction assembly 30 is partially disposed in the receiving portion 11 and is located above the high-pressure inflation assembly 20 in the height direction (Z direction) of the housing 10. The orthographic projection of the low-pressure blowing and suction assembly 30 on the side of the receiving portion 11 in the width direction (X direction) coincides with the orthographic projection of the high-pressure inflation assembly 20 on the side of the receiving portion 11 in the width direction (X direction).

[0039] It should be noted that the high-pressure inflation component 20 in this application is used to input high-pressure gas into the device to be inflated, and the low-pressure inflation and suction component 30 is used to input low-pressure gas into the device to be inflated, to clean the vehicle with the blown low-pressure gas, or to deflate or vacuum the device to be deflated. That is, the high- and low-pressure air pump in this application can integrate multiple functions such as high-pressure inflation, low-pressure inflation, and vacuuming, thereby increasing the functionality of the high- and low-pressure air pump and making it suitable for various working conditions. Meanwhile, the high and low pressure air pump in this application is not only compact and small in size, but also arranges the low-pressure blowing and suction assembly 30 and the high-pressure inflation assembly 20 vertically along the height direction (Z direction) of the receiving part 11, and the orthographic projection of the low-pressure blowing and suction assembly 30 on the side of the receiving part 11 in the width direction (X direction) coincides with the orthographic projection of the high-pressure inflation assembly 20 on the side of the receiving part 11 in the width direction (X direction). This design not only reduces the size of the entire high and low pressure air pump to a certain extent, such as by reducing the height and length of the entire high and low pressure air pump, but also ensures that the height and length of the high and low pressure air pump are not too high or too long. At the same time, this design also keeps the center of gravity of the entire high and low pressure air pump in the center, so that there will be no center of gravity shift, thus improving the stability of the low-pressure air pump during operation.

[0040] See Figure 6 In one specific embodiment, the receiving portion 11 has a recess 111 on one side along its width direction (X direction), and a mounting portion 1111 is disposed on the recess. A power supply assembly (not shown in the figure) is disposed on the mounting portion. The power supply assembly is detachably connected to the mounting portion. With this design, even if the power supply assembly is added, the center of gravity of the entire high and low pressure air pump is still located in the central area of ​​the high and low pressure air pump. When moving the high and low pressure air pump, there will be no shift in the center of gravity or the entire high and low pressure air pump, and it is also more labor-saving.

[0041] See Figure 1 , Figure 4 and Figure 5In one specific embodiment, the housing 10 includes a first cover plate 14, a first storage portion 12, a second storage portion 13, and a second cover plate 15.

The second storage portion 13 is disposed on the side of the receiving portion 11 away from the low-pressure inflation component, and the second cover plate 15 is disposed on the side of the second storage portion 13 away from the receiving portion 11, and the second cover plate 15 is hinged to the second storage portion 13.

The low pressure hose 61 and at least three low pressure accessories 62 are detachably disposed in the first storage part 12. In order to prevent the low pressure hose 61 and at least three low pressure accessories 62 from shaking in the first storage part 12 when the high and low pressure air pump 22 is moved, causing damage to the low pressure hose 61 and at least three low pressure accessories 62, it is considered that a low pressure hose storage groove 121 and at least three low pressure accessory storage grooves 122 are disposed in the first storage part 12.
