The outer shell 10 is provided with a receiving cavity 105, and the outer shell 10 extends along the longitudinal axis A in the up-down direction; the portable charging and suction pump 100 also includes an accessory module 1, and the accessory module 1 includes a battery pack 13 for powering the portable charging and suction pump 100; the portable charging and suction pump 100 also includes a charging and suction assembly 2, and the charging and suction assembly 2 is received in the receiving cavity 105; wherein the charging and suction assembly 2 includes: a high-voltage module 11, and the high-voltage module 11 includes: a first motor axis C (such as Figure 8The first motor 110 is a first motor 110 (not shown) that rotates, and a cylinder assembly 111 connected to the first motor 110, the cylinder assembly 111 includes a piston (not shown) and a cylinder body 1110; the first motor 110 drives the piston to reciprocate along the central extension axis B in the cylinder body 1110 to achieve high-pressure inflation; the inflation and suction assembly 2 also includes a low-pressure module 12, the low-pressure module 12 includes a second motor axis D (as shown) that rotates Figure 8 The second motor 120 (shown) rotates, and the fan 3 connected to the second motor 120, the second motor 120 drives the impeller (not shown) disposed in the fan 3 to rotate, so as to achieve low-pressure inflation or suction.

[0154] The gap between the charging and suction component 2 and the outer shell 10 is defined as the available space of the portable charging and suction pump 100, and the available space is used to set the accessory module 1 other than the charging and suction component 2; when the packaging volume of the portable charging and suction pump 100 does not exceed 6L, the ratio of the available space to the packaging volume of the portable charging and suction pump 100 is not less than 45%.

[0155] like Figure 1 and Fig.19 As shown, in this application, excluding the handle 15, the length L of the portable charging and suction pump is defined as the maximum straight-line distance of the portable charging and suction pump in the left-right direction. In this embodiment, the length L is specifically the straight-line distance between the third side wall 103 of the outer shell 10 and the end of the high-pressure outlet opening 1041 or the end of the low-pressure outlet opening 1042 in the left-right direction; the width W is defined as the maximum straight-line distance of the portable charging and suction pump in the front-to-back direction. In this embodiment, the width W is specifically the longest straight-line distance between the first side wall 101 and the second side wall 102 of the outer shell 10 in the front-to-back direction; the height H is defined as the maximum straight-line distance of the portable charging and suction pump in the up-down direction. In this embodiment, the height H is specifically the straight-line distance between the upper surface of the cover 18 and the supporting surface of the portable charging and suction pump located below in the up-down direction. The packaging volume V of the portable charging and suction pump 100 defined by the outer shell 10 refers to the product of L, W and H.

[0156] like Fig. 20A and Fig. 20B As shown, in this application, the length L1 of the charging and suction assembly 2 is defined as the straight-line distance between the cooling fan 1101 and the end of the air outlet pipe 1211 in the left-right direction; the width W1 is defined as the straight-line distance between the front end of the driven wheel 1122 and the rear end of the fan housing 121 in the front-back direction; the height H1 is defined as the straight-line distance between the end of the air inlet pipe 1210 and the lower end of the driven wheel 1122 in the up-down direction. The packaging volume V1 of the charging and suction assembly 2 refers to the product of L1, W1 and 1H.

[0157] The packaging volume difference between the outer shell 10 and the inflation / suction component 2 is defined as △V=V-V1. However, since the inflation / suction component 2 is not a regular entity, it is conceivable that there is a gap between the smallest rectangular parallelepiped that can contain the inflation / suction component 2 and the entity of the inflation / suction component 2. These spaces become part of the available space, and therefore the available space volume V2≥△V.

[0158] Such a layout makes it possible to fully utilize the space inside the outer shell, not only for storing the charging and suction components, but also for making full use of the gaps to layout the accessory modules. As the saying goes, a small sparrow has all the internal organs. The portable charging and suction pump in this application is multifunctional: it includes both high-pressure inflation and low-pressure inflation and low-pressure suction, meeting various charging and suction needs of users; at the same time, the portable charging and suction pump is small in size, and the packaging volume does not exceed 6L, which is convenient for users to carry and use. With such a small packaging volume, the portable charging and suction pump can also accommodate the charging and suction components and accessory modules. The ratio of available space to the packaging volume of the portable charging and suction pump is not less than 45%, which makes the space utilization rate in the portable charging and suction pump high and the structure compact.

[0159] In some embodiments, Figure 1 As shown, the outer shell 10 of the portable charging and suction pump 100 can be generally in the shape of a rectangular parallelepiped, and the edges between adjacent faces of the outer shell 10 can have smooth chamfers, so that the volume of the outer shell 10 is reduced and more beautiful. The outer shell 10 may include a first side wall 101 and a second side wall 102 opposite to each other, and a third side wall 103 and a fourth side wall 104 opposite to each other, wherein the first side wall 101 and the second side wall 102 are arranged in the front-to-back direction perpendicular to the up-down direction (i.e., the width direction of the portable charging and suction pump); the third side wall 103 and the fourth side wall 104 are arranged in the left-to-right direction perpendicular to the up-down direction (i.e., the length direction of the portable charging and suction pump). The outer shell 10 includes a main body shell 106, the main body shell 106 has an upper end face 106A and a lower end face 106B, and the main body shell 106 also extends along the longitudinal axis A in the upper and lower directions.

[0160] In some embodiments, Figure 3 and Figures 4A-4D As shown, the high-voltage module 11 also includes a transmission assembly 112 arranged between the first motor 110 and the cylinder assembly 111. The first motor 110 and the transmission assembly 112 are supported on a fixed bracket (not shown). The transmission assembly 112 connects the piston rod 1112 and the output shaft of the first motor 110 (not shown). The transmission assembly 112 converts the rotational motion of the output shaft of the first motor 110 into linear motion to transmit it to the piston rod 1112.

[0161] Specifically, the transmission assembly 112 includes a transmission member and an eccentric wheel 1123. In the embodiment of the present application, the transmission member is a gear set, and the gear set includes a driving wheel 1121 and a driven wheel 1122. The driving wheel 1121 of the gear set is installed on the output shaft of the first motor 110. In other embodiments, the transmission member can also be set to other, such as rack transmission, chain transmission, connecting rod transmission, belt transmission, etc., which are not specifically limited here and are determined according to actual conditions. The eccentric wheel 1123 is connected to the driven wheel 1122 in the gear set, and the eccentric wheel 1123 is driven by the driven wheel 1122 to rotate in a circle. The piston rod 1112 is connected to the eccentric wheel 1124, and the piston rod 1112 is pushed by the eccentric wheel 1123 to make reciprocating linear motion. When the gear set drives the piston rod 1112 to move toward the direction close to the high-pressure air outlet 1111, the volume of the gas compressed and accumulated in the cylinder 1110 becomes smaller, and the cylinder 1110 is connected to the high-pressure air outlet 1111 through the three-way joint 1113. The gas generated by the cylinder 1110 can be transported to the equipment to be inflated along the high-pressure inflation hose 113.

[0162] In some embodiments, Figure 3 As shown, the high-pressure module 11 also includes a three-way joint 1113 connected to the cylinder body 1110, and the three-way joint 1113 is connected to the high-pressure gas outlet 1111; the first motor 110 drives the piston to reciprocate along the central extension axis in the cylinder body 1110 to achieve high-pressure inflation, and discharges the compressed gas through the high-pressure gas outlet 1111 connected to the three-way joint 1113.

[0163] In some embodiments, Figure 3 As shown, the first end of the three-way connector 1113 is connected to the air outlet of the cylinder 1110, the second end is connected to the high-pressure air outlet 1111, and the third end is connected to an air pressure sensor (not shown). The air pressure sensor monitors the air pressure value in real time and compares it with the target air pressure value. When the target air pressure value is exceeded, inflation is stopped, thereby realizing automatic control of the portable inflation and suction pump.

[0164] In some embodiments, Figure 3 As shown, the cylinder body 1110 and the fixing bracket are die-cast as an integrated design, and a reinforcing rib 1114 is provided at the junction of the cylinder body 1110 and the fixing bracket, so that the overall support can be enhanced.

[0165] In some embodiments, Figure 3 As shown, the high voltage module 11 further includes a first motor housing 110A, 110B, and the first motor housing 110A, 110B covers the first motor 110 and is fixedly installed in the receiving cavity 105 .

[0166] In some embodiments, Figure 5 and Figure 6As shown, a vibration-damping ring 1102 is provided at one end of the first motor 110 away from the high-pressure air outlet 1111, and the vibration-damping ring 1102 is arranged between the first motor housing 110A, 110B and the first motor 110. Furthermore, at one end of the first motor 110 close to the high-pressure air outlet 1111, vibration-damping pads 1103A, 1103B are arranged between the fixing bracket and the first motor housing 110A, 110B. The high-voltage module will vibrate when working, and the vibration may cause some adverse effects, such as numbness of the user's hands when operating or the portable charging and suction pump being placed unsteadily when working. Therefore, the vibration-damping ring and the vibration-damping pad can reduce the vibration of the high-voltage module, facilitate user operation and improve the stability of the charging and suction pump when working.

[0167] In some embodiments, when the packaging volume of the portable charging and suction pump 100 does not exceed 5L, the ratio of the available space to the packaging volume of the portable charging and suction pump is not less than 48%. This configuration allows the portable charging and suction pump to be small in size and easy to carry, while also having a relatively high available space for placing accessory modules, with high space utilization and compact structure.

[0168] In some embodiments, Figure 2B-2E and Figures 4A-4D As shown, when projected from the left and right directions, the central extension axes B, Ba, Bb, and Bc are respectively arranged to be inclined relative to the longitudinal axis A. That is to say, when projected from the left and right directions, the central extension axes B, Ba, Bb, and Bc intersect with the longitudinal extension axis A respectively, and the corresponding intersections are acute angles α, αa, αb, αc or obtuse angles β, βa, βb, and βc, wherein the acute angle α and the obtuse angle β are complementary angles. With such a layout, the cylinder assembly of the high-pressure module can be placed obliquely in the outer shell, and the layout of the portable charging and suction pump in the up and down direction (i.e., the height direction) or the front and back direction (i.e., the width direction) is more compact, so that the space in the height direction and the width direction of the outer shell can be saved for the arrangement of the accessory modules, further making the portable charging and suction pump have high space utilization and compact structure. Optionally, when projected from the front and back directions, the central extension axes B, Ba, Bb, and Bc are respectively arranged to be inclined relative to the longitudinal axis A. At this time, the charging and suction assembly is inclined relative to Figure 2B The filling and suction components in the tank are rotated 90 degrees.

[0169] In some embodiments, Figure 2B-2E and Figures 4A-4DAs shown, the central extension axes B, Ba, Bb, and Bc are inclined at angles in the range of 10° to 80° or in the range of 100° to 170° relative to the longitudinal axis A. Such an arrangement allows the cylinder assembly to be tilted in the outer shell, and the tilt angle can be adjusted between the minimum angle and the maximum angle according to the arrangement of the accessory modules, so that the portable charging and suction pump saves space in the up-down direction (i.e., the height direction) or the front-back direction (i.e., the width direction) for placing the accessory modules, and the space utilization rate is high.

[0170] Specifically, Figure 2B and Figure 4A As shown, it is the first embodiment of the cylinder assembly tilting in the present application, wherein the cylinder assembly tilts at a first angle, that is, the angle at which the central extension axis B is tilted relative to the longitudinal axis A is 25°; Figure 2C and Figure 4B As shown, it is a second embodiment of the cylinder assembly tilting in the present application, wherein the cylinder assembly tilts at a second angle, that is, the angle at which the central extension axis Ba is tilted relative to the longitudinal axis A is 10°; Figure 2D and Figure 4C As shown, it is a third embodiment of the cylinder assembly tilting in the present application, wherein the cylinder assembly tilts at a third angle, that is, the angle at which the central extension axis Bb is tilted relative to the longitudinal axis A is 45°; Figure 2E and Figure 4D , which is a fourth embodiment of the tilted cylinder assembly in the present application, wherein the cylinder assembly is tilted at a fourth angle, that is, the angle at which the central extension axis Bc is tilted relative to the longitudinal axis A is 80°.

[0171] As shown in the following table, the change in the inclination angle between the central extension axis and the longitudinal axis is compared with the outer shell packaging volume and the minimum available space:

[0172]

[0173]

[0174] As can be seen from the table above, the tilted angle of the cylinder assembly in the outer shell will affect the packaging volume of the charging and suction assembly and the outer shell, specifically affecting the height and width of the charging and suction assembly and the outer shell, while the length remains unchanged, so the length value is not listed in the table above.

[0175] In order to simplify the description, the influence when the tilt angle of the cylinder assembly is an acute angle will be explained below. The influence when the tilt angle of the cylinder assembly is an obtuse angle is the same and will not be repeated. Specifically, when the cylinder assembly is placed vertically, that is, the tilt angle is 0°, the height of the charging and suction assembly and the outer shell are both the highest. When the cylinder assembly is placed horizontally, that is, the tilt angle is 90°, the width of the charging and suction assembly and the outer shell are both the highest. When the tilt angle of the cylinder assembly is rotated from 10° to 80°, the height of the charging and suction assembly will be reduced, so that available space can be freed up in the height direction of the outer shell to place the accessory module, and the space utilization rate is high. Or when the tilt angle of the cylinder assembly is rotated from 80° to 10°, the width of the charging and suction assembly will be reduced, so that available space can be freed up in the width direction of the outer shell to place the accessory module, and the space utilization rate is also high.

[0176] At the same time, as shown in the above table, the packaging volume of the outer shell does not exceed 6L, and the minimum available space ratio, that is, the ratio of the available space to the packaging volume of the outer shell, is not less than 45%. Optionally, the packaging volume of the outer shell does not exceed 5L, and the minimum available space ratio is not less than 48%.

[0177] In the present application, in the first embodiment of the tilted cylinder assembly, the central extension axis B is tilted at an angle of 25° relative to the longitudinal axis A. At this time, the packaging volume of the outer shell is about 4L, and the minimum available space ratio is not less than 55%. When the tilt angles are 45° and 80°, the packaging volume of the outer shell is about 4L, and the minimum available space ratio is lower than the minimum available space ratio when the tilt angle is 25°; when the tilt angle is 10°, although the packaging volume and the minimum available space ratio of the outer shell are higher than the tilt angle of 25°, the height of the outer shell is higher when the tilt angle is 10°. In the present application, when the tilt angle is 25°, the balance of the length, width and height ratio of the whole machine is comprehensively considered. At the same time, the cylinder assembly is tilted, which reduces the width or height of the charging and suction assembly compared to the horizontal or vertical placement of the cylinder assembly, and can free up space to place the accessory module. The structure is compact and the space utilization rate is high.

[0178] In some embodiments, Fig.9A and Fig. 9B As shown, the projections of the low-pressure module 12 and the high-pressure module 11 in the vertical direction at least partially overlap. Such a layout further makes full use of the space in the outer shell 10 to store the charging and suction assembly 2, which can reduce the size of the charging and suction assembly 2 in the length direction or width direction, and can also be used for the placement of accessory modules, so that the portable charging and suction pump 100 is miniaturized and has high space utilization.

[0179] In some embodiments, Fig.9AAs shown, the projections of the fan 3 and the high-voltage module 11 in the vertical direction at least partially overlap. Since the projection area of ​​the fan 3 in the vertical direction is large, there is installation space above or below the fan 3 that can be used to place the high-voltage module 11. Such a layout makes the portable charging and suction pump 100 small and has high space utilization.

[0180] In some embodiments, Fig.9A As shown, the projections of the fan 3 and at least one of the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the up and down directions at least partially overlap, thereby saving space in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction) of the portable charging and suction pump 100.

[0181] In some embodiments, Fig.9A As shown, when projected in the up-down direction, the projection area overlaps 50%-90% between the high pressure module 11 and the low pressure module 12. Such a layout reduces the length and width of the charging and suction assembly, making the portable charging and suction pump 100 miniaturized.

[0182] In some embodiments, Figure 3 As shown, the low-pressure module 12 includes a second motor 120, a fan 3 connected to the second motor 120, and an air outlet arranged on the portable charging and suction pump 100. The fan 3 includes an impeller (not shown), a fan housing 121 for accommodating the impeller, and an air inlet pipe 1210 arranged on the fan housing 121. The air inlet pipe 1210 corresponds to the position of the air outlet on the portable charging and suction pump 100. The impeller is arranged on the output shaft of the second motor 120. The second motor 120 can drive the impeller to rotate, and the low-pressure gas flows, thereby sucking air into external objects connected to the low-pressure module 12.

[0183] In some embodiments, Figure 1 and Fig.13A As shown, a main view of the charging and suction assembly 2 and the battery pack 13 is shown. The second motor axis D is parallel to the longitudinal axis A, and the fan 3 is transversely arranged at the end of the second motor 120; the first motor axis C and the second motor axis D are arranged perpendicularly, and the fan 3 extends toward the end of the second motor 120 to form an installation space, and at least part of the high-voltage module 11 is arranged in the installation space.

[0184] Specifically, Figure 1 , Fig.9A and Fig.13AAs shown, in the present application, the projections of at least one of the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the vertical direction at least partially overlap, so that the portable charging and suction pump 100 saves space in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction), and the structure is compact. More specifically, the projections of the fan 3 of the low-pressure module 12 and the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the vertical direction at least partially overlap. Since the fan housing 121 is roughly circular, the second motor axis D is set at the center of the circle, and the lower surface of the fan housing 121 extends downward to the installation space formed by the end of the second motor 120, at least part of the high-pressure module 11 is set below the fan housing 121 or the impeller, making full use of the installation space at the bottom of the fan housing 121 or the impeller, so that the low-pressure module 12 and the high-pressure module 11 are arranged more compactly.

[0185] In some embodiments, Fig.13A As shown, the fan 3 further includes an air outlet pipe 1211 for discharging low-pressure gas, thereby inflating external objects connected to the low-pressure module 12, and the central extension axis Y of the air outlet pipe 1211 is parallel to the first motor axis C. With such a layout, the length of the bottom of the fan is fully utilized to place the first motor, and the space utilization rate is high.

[0186] Specifically, Fig.13A As shown, the central extension axis Y of the air outlet pipe 1211 is perpendicular to the second motor axis D and parallel to the first motor axis C, that is, the air outlet pipe 1211 is extended horizontally, and the fan housing 1211 of the fan 3 and the air outlet pipe 1211 have the longest dimension in the left-right direction, as shown in FIG. Fig. 20B As shown, the length L1 of the high-voltage module 11 is greater than the width W1. The length of the high-voltage module is arranged along the central extension axis of the air outlet duct, that is, most of the high-voltage modules are arranged as far as possible within the longest dimension range in the left and right directions of the fan, which can save space in the left and right directions and has a compact structure.

[0187] In some embodiments, Fig.9A As shown, the air outlet pipe 1211 and the cylinder assembly 111 at least partially overlap in the up and down direction, so that the space below the air outlet pipe 1211 is utilized to arrange the cylinder assembly 111.

[0188] Optionally, the air outlet pipe 1211 and the cylinder assembly 111 are both disposed close to the third side wall 103 or the fourth side wall 104 of the outer shell 10 .

[0189] In some embodiments, Figure 3 and Figure 8As shown, the second motor axis D extends in the up-down direction and is arranged parallel to the longitudinal extension axis of the outer shell 10, that is, the second motor 120 is vertically placed in the accommodating cavity, thereby utilizing the space in the up-down direction (that is, the height direction) in the outer shell 10 to arrange the low-voltage module 12.

[0190] In some embodiments, Figure 3 and Figure 8 As shown, the air inlet pipe 1210 on the fan housing 121 has a central extension axis X, and the air outlet pipe 1211 has a central extension axis Y. In the embodiment of the present application, the central extension axis X is arranged parallel to the second motor axis D, and the central extension axis Y is arranged perpendicular to the second motor axis D. Optionally, the central extension axis X coincides with the second motor axis D. In other embodiments, the central extension axis X is arranged perpendicular to the second motor axis D, and the central extension axis Y is arranged parallel to the second motor axis D. Optionally, the central extension axis Y coincides with the second motor axis D.

[0191] In some embodiments, Figure 8 As shown, the first motor 110 of the high-voltage module 11 has a first motor axis C extending in the left-right direction, that is, the first motor 110 is horizontally placed in the accommodating cavity 105, thereby utilizing the space in the left-right direction (i.e., the length direction) in the outer shell 10 to arrange the high-voltage module 11.

[0192] In some embodiments, Figure 8 As shown, the first motor axis C is arranged perpendicular to the second motor axis D.

[0193] In some embodiments, Figure 4A As shown, the first motor 110 drives the piston to reciprocate along the central extension axis B in the cylinder 1110 , and the central extension axis B is inclined relative to the second motor axis D, and the inclination angle is an acute angle or an obtuse angle.

[0194] In some embodiments, Figure 8 As shown, the second motor 120 of the low-voltage module 12 is placed at an upper position in the outer shell 10 in the up-down direction relative to the first motor 110, and the space between the second motor 120 and the lower end of the outer shell 10 is used to place the first motor 110, and the first motor 110 is placed at a lower position in the outer shell 10 in the up-down direction relative to the second motor 120.

[0195] In addition to utilizing space for arrangement, the overall position of the high-pressure module 11 is set at a lower position of the outer shell 10 relative to the low-pressure module 12, so that the center of gravity of the portable charging and suction pump 100 is lower, which makes it more stable when the user operates it. At the same time, since the high-pressure module 11 will generate vibrations, if it is placed in a higher position, it will cause the portable charging and suction pump 100 to shake during use, which is inconvenient for the user to operate.

[0196] In some embodiments, the second motor 120 at least partially overlaps with at least one of the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the up and down direction, thereby saving space in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction) of the portable charging and suction pump 100.

[0197] In the implementation mode of the present application, Fig. 9B As shown, the second motor 120 at least partially overlaps with the first motor 110 in the up and down direction.

[0198] In order to further make full use of the space in the outer shell 10 to accommodate the charging and suction components, the portable charging and suction pump 100 is miniaturized. Figures 4A-4D As shown, the projections of the low pressure module 12 and the high pressure module 11 in the left and right directions at least partially overlap. Such a layout saves space in the front-to-back direction (ie, the width direction) and the left-to-right direction (ie, the length direction) of the portable charging and suction pump 100.

[0199] In some embodiments, Figures 4A-4D As shown, the projections of the second motor 120 and the cylinder assembly 111 in the left-right direction at least partially overlap, so that the portable charging and suction pump 100 saves space in the up-down direction (ie, the height direction).

[0200] In some embodiments, the fan 3 at least partially overlaps with at least one of the first motor 110 , the cylinder assembly 111 , and the transmission assembly 112 in the left-right direction.

[0201] In some embodiments, the second motor 120 at least partially overlaps with at least one of the first motor 110 , the cylinder assembly 111 , and the transmission assembly 112 in the left-right direction.

[0202] In order to further fully utilize the packaging space of the outer shell 10 to accommodate the battery pack 13, as shown in FIG. Fig.13A As shown, the projections of the battery pack 13 and the charging and suction assembly 2 in the front-to-back direction at least partially overlap. Thus, after the battery pack 13 is combined with the high-voltage module 11 and the low-voltage module 12, the space can be reduced in the height direction and the length direction, making the portable charging and suction pump compact.

[0203] In some embodiments, Fig.13A As shown, the battery pack 13 is arranged behind the high-voltage module 11 and the low-voltage module 12, and the sliding direction of the battery pack 13 is perpendicular to the first motor axis C and parallel to the second motor axis D. Such an arrangement saves space in the vertical direction (i.e., the height direction) and the left-right direction (i.e., the length direction) between the battery pack 13 and the high-voltage module 11 and the low-voltage module 12, and the arrangement is more compact.

[0204] In order to further fully utilize the packaging space of the outer shell 10 to accommodate the battery pack 13, as shown in FIG. Fig. 13B As shown, the projections of the battery pack 13 and the charging and suction assembly 2 in the up-down direction at least partially overlap, so that the arrangement between the battery pack 13 and the charging and suction assembly 2 saves space in the front-to-back direction (ie, the width direction).

[0205] Furthermore, if Fig. 13B As shown, the projections of the battery pack 13 and the low-voltage module 12 in the up and down directions at least partially overlap.

[0206] Furthermore, if Fig. 13B As shown, the low-voltage module 12 includes a fan housing 121 , and the projections of the battery pack 13 and the fan housing 121 in the up and down directions at least partially overlap.

[0207] Specifically, the fan housing 121 includes a circular part, the second motor axis D is arranged at the center of the circle, and the lower surface of the fan housing 121 extends downward to the cylindrical space formed by the end of the second motor 120 to form an installation space. At least part of the high-voltage module 11 is arranged under the front half of the fan housing 121, and at least part of the battery pack 13 is arranged under the rear half of the fan housing 121. The space under the fan housing 121 is fully utilized, so that the battery pack 13 is close to the high-voltage module 11 and the low-voltage module 12, and the distance between the battery pack 13 and the high-voltage module 11 and the low-voltage module 12 is shortened to the shortest, and the arrangement is more compact.

[0208] In some embodiments, Figure 10-11 As shown, in the front-to-back direction, the battery pack 13 is disposed on one side of the outer shell 10. The battery pack 13 is detachably mounted on the outer shell 10 in the up-down direction.

[0209] Disposing the battery pack 13 on one side of the outer shell 10 can make the battery pack 13 close to the high-voltage module 11 or the low-voltage module 12, and reduce the distance between the battery pack 13 and the high-voltage module 11 or the low-voltage module 12, so that the portable charging and suction pump can be more compact while ensuring its performance.

[0210] In some embodiments, Fig.10 and Fig.11As shown, the outer shell 10 is provided with a battery pack mating portion 130, and the battery pack 13 is slidably matched with the battery mating portion 130 when installed, and the sliding direction of the battery pack 13 is parallel to the longitudinal extension direction of the outer shell 10. Further, when the battery pack 13 is assembled, it slides toward the upper end surface 106A of the main body shell 106, and further, the battery pack 13 slides from the lower end surface 106B of the main body shell 10 toward the upper end surface 106A. Such a configuration facilitates the charging of the battery pack 13, and facilitates the application of the battery pack 13 to other matching power tools or the portable charging and suction pump using the battery pack 13 of other matching power tools, that is, multiple machines can share one battery pack 13, saving costs.

[0211] In an embodiment of the present application, the battery pack 13 is vertically mounted on one side of the outer shell 10 . In other embodiments, the battery pack 13 can be placed horizontally at different positions of the portable charging and suction pump, or can be vertically mounted at other positions of the outer shell 10 .

[0212] In some embodiments, Figures 10 to 12 As shown, one side of the outer shell 10 has a recessed portion 107, and the battery pack 13 is at least partially accommodated in the recessed portion 107. Thus, a part of the space of the outer shell 10 is used to accommodate the battery pack 13, and the space utilization rate of the whole device is high, the volume is small, and it is easy to carry.

[0213] Optionally, the overall shape of the battery pack 13 is similar to the recessed portion 107 , so that the battery pack 13 can be installed in the recessed portion 107 under the premise of maximization, and the space at the second side wall 102 of the outer shell 10 will not be wasted.

[0214] Optionally, the width of the entire recessed portion 107 in the front-to-back direction is smaller than the height in the up-down direction, so that the width of the second side wall 102 shell 10 in the front-to-back direction is relatively small, which facilitates the miniaturization of the portable charging and suction pump.

[0215] In some embodiments, when the battery pack 13 is accommodated in the recessed portion 107, the battery pack 13 does not extend beyond the outer shell 10. With such a design, there is no protruding structure on the side wall of the portable charging and suction pump, and when the side wall of the outer shell is used as a support surface, the stability of the placement of the portable charging and suction pump is not affected.

[0216] In the implementation mode of the present application, Fig.12 As shown, specifically, the rear end face of the battery pack 13 does not exceed the second side wall 102 of the outer shell 10, and the left end face and the right end face of the battery pack 13 do not exceed the third side wall 103 and the fourth side wall 104 of the outer shell, respectively.

[0217] In some embodiments, Figure 10 to Figure 11As shown, the recessed portion 107 extends in the up-down direction and penetrates the lower end surface 106B of the main body housing 106, so that the battery pack 13 can be removed from the lower end surface 106B.

[0218] Optionally, the recessed portion 107 does not penetrate the upper end surface 106A of the host housing 106 , and the recessed portion 107 has a top portion 1070 , which does not exceed the upper end surface 106A of the host housing 106 in the up and down directions.

[0219] When the battery pack 13 is assembled, it is set to slide from the lower end surface 106B toward the upper end surface 106A, and the battery pack 13 can be removed from the lower end surface 106B, which makes it easier to set the upper end surface 106A of the portable charging and suction pump 100 to a complete plane. If the battery pack 13 is inserted by sliding from the upper end surface 106A toward the lower end surface 106B, a gap will inevitably appear on the upper end surface of the main body shell, destroying the integrity of the portable charging and suction pump. The design of this embodiment can solve this problem and ensure the integrity and aesthetics of the appearance of the entire machine.

[0220] In some embodiments, the host housing 106 has at least one auxiliary grip portion 108 , and a hollow portion communicating with the recessed portion 107 is formed between the host housing 10 and the auxiliary grip portion 108 .

[0221] With such arrangement, when the portable charging and suction pump 100 is not installed with the battery pack 13 , the user's hand can pass through the hollow portion and the recessed portion 107 to hold the auxiliary gripping portion 108 to move or operate the portable charging and suction pump.

[0222] In some embodiments, Fig.11 As shown, the auxiliary grip portion 108 includes a first auxiliary grip portion 108A and a second auxiliary grip portion 108B, and a first hollow portion 1044 and a second hollow portion 1034 connecting the recessed portion 107 are respectively formed between the main housing 106 and the first auxiliary grip portion 108A and the second auxiliary grip portion 108B.

[0223] Optionally, the first auxiliary gripping portion 108A and the second auxiliary gripping portion 108B, and the first hollow portion 1044 and the second hollow portion 1034 are disposed symmetrically.

[0224] Optionally, when the portable charging and suction pump 100 is installed with the battery pack 13 , there is a gap between the battery pack 13 and the right and left sides (not shown) of the recessed portion 107 , and the gap is large enough for the user's hand to pass through.

[0225] In some embodiments, the ratio between the height of the portable charging pump 100 and the battery pack 13 is in the range of 1.2:1 to 1.8:1, wherein the height of the portable charging pump is the maximum straight-line distance in the up and down directions, and the height of the battery pack is the straight-line distance between the upper end surface of the battery pack and the lower end surface of the battery pack in the up and down directions.

[0226] In some embodiments, the ratio between the width of the portable charging pump 100 and the battery pack 13 is in the range of 3:1 to 4:1, wherein the width of the portable charging pump is the maximum straight-line distance in the front-to-back direction, and the width of the battery pack is the straight-line distance between the front end face of the battery pack and the rear end face of the battery pack in the front-to-back direction.

[0227] In some embodiments, the ratio between the length of the portable charging pump 100 and the length of the battery pack 13 is in the range of 1.8:1 to 2.4:1, wherein the length of the portable charging pump is the maximum straight-line distance in the left-right direction, and the length of the battery pack is the straight-line distance between the left end face of the battery pack and the right end face of the battery pack in the left-right direction.

[0228] In order to facilitate the connection between the high-voltage module 11 and the low-voltage module 12 and external objects, such as Figure 1 As shown, the accessory module 1 also includes high-pressure inflatable accessories 113, 114, 115 and low-pressure inflatable and absorbent components 122, 123, 124, 125; the available space is further used to store high-pressure inflatable accessories 113, 114, 115 and low-pressure inflatable and absorbent components 122, 123, 124, 125, and the projections of the high-pressure inflatable accessories 113, 114, 115 and low-pressure inflatable and absorbent components 122, 123, 124, 125 in the up and down directions at least partially overlap with the projections of the inflatable and absorbent component 2, so that the portable inflatable and absorbent pump 100 is reduced in size in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction), and the structure is compact.

[0229] In some embodiments, Fig.18A and Fig.18B As shown, the low-pressure air-intake and air-filling accessories 122, 123, 124, 125 at least partially overlap with the high-pressure module 11 or the low-pressure module 12 in the vertical direction. Such an arrangement makes the low-pressure air-intake and air-filling accessories close to the high-pressure module or the low-pressure module, and the arrangement is more compact.

[0230] In some embodiments, Fig.17 As shown, the projections of the high-pressure inflation accessories 113, 114, 115 and the low-pressure inflation and suction components 122, 123, 124, 125 and the inflation and suction assembly 2 in the front-to-back direction at least partially overlap, so that the portable inflation and suction pump 100 is reduced in size in the up-down direction (i.e., the height direction) and the left-right direction (i.e., the length direction), and has a compact structure.

[0231] In some embodiments, Figure 1and Figure 2A As shown, the portable charging and suction pump 100 also includes a storage portion 14 for storing high-pressure charging accessories 113, 114, 115 and low-pressure charging and suction components 122, 123, 124, 125. The storage portion 14 includes a high-pressure accessory storage portion 14B and a low-pressure accessory storage portion 14A that are separately arranged. The high-pressure accessory storage portion 14B is close to the high-pressure module 11, and the low-pressure accessory storage portion 14A is close to the low-pressure module 12. Such a layout is for more convenient access to high-pressure charging accessories or low-pressure charging and suction components.

[0232] In some embodiments, Figure 1 As shown, the high-pressure accessory storage portion 14B is disposed along the longitudinal axis A at the top of the portable charging and suction pump 100 , and the low-pressure accessory storage portion 14A is disposed along the longitudinal axis A at the bottom of the portable charging and suction pump 100 .

[0233] In some embodiments, Figure 1 As shown, the low-voltage accessory storage section 14A and the high-voltage accessory storage section 14B are separated from each other in the up-down direction.

[0234] In some embodiments, Figure 1 As shown, the low-pressure accessory storage part 14A and the high-pressure accessory storage part 14B are connected to the main body housing 106, and are separated by the main body housing 106 at both ends in the up and down directions, making full use of the space in the up and down direction (i.e., the height direction) of the portable charging and suction pump 100 to arrange the accessory storage part 14.

[0235] Specifically, in this application, Figure 2A and Figure 2B As shown, relative to the high-pressure module 11, the low-pressure module 12 is vertically placed in the upper position of the main housing 106, and relative to the low-pressure module 12, the high-pressure module 11 is horizontally placed in the lower position of the main housing 106. Therefore, the low-pressure accessory storage part 14A is arranged above the main housing 106 close to the low-pressure module 12, and the high-pressure accessory storage part 14B is arranged below the main housing 106 close to the high-pressure module 11.

[0236] In some embodiments, in order to further fully utilize the internal space of the portable charging and suction pump, without increasing the structural size of the portable charging and suction pump 100, as shown in FIG. Figure 1 and Figures 14A-14C As shown, the high-voltage accessory storage portion 14B includes a high-voltage accessory housing 140B and a high-voltage accessory storage groove 141B. The high-voltage accessory housing 140B is recessed toward the accommodating cavity 105 to form at least one high-voltage accessory storage groove 141B.

[0237] In some embodiments, a first gap space (not shown) is formed between the inner wall of the main housing 106 and the high voltage module 11 , and the high voltage accessory storage portion 14B is at least partially accommodated in the first gap space.

[0238] Specifically, the main body housing 106 has an open upper end surface 106A and a lower end surface 106B, the receiving cavity 105 is connected with the upper end and the lower end, and the high-voltage accessory storage portion 14B extends into the first gap space through the open lower end surface 106B.

[0239] In some embodiments, Figure 1 and Figures 14A-14C As shown, the high-pressure accessory storage slot 141B includes a first high-pressure accessory storage slot 1410B for accommodating a high-pressure inflation hose 113 and a second high-pressure accessory storage slot 1411B for accommodating other high-pressure accessory heads, wherein the high-pressure inflation hose 113 can be detachably connected to the high-pressure inflation opening 1041 of the high-pressure module 11, thereby facilitating the connection of the high-pressure module 11 with external inflatable items for high-pressure inflation.

[0240] In some embodiments, at least a portion of the first high-voltage accessory receiving slot 1410B extends through the open lower end surface 106B into the first gap space.

[0241] In some embodiments, the first high-voltage accessory storage slot 1410B surrounds the second high-voltage accessory storage slot 1411B.

[0242] In some embodiments, the first high-pressure accessory storage groove 1410B partially extends along the four sides of the bottom surface of the high-pressure accessory housing 140B. Since the first high-pressure accessory storage groove 1410B is used to store a longer high-pressure inflation hose 113, through such a design, the high-pressure inflation accessories can be reasonably arranged in the high-pressure accessory storage part without taking up too much space.

[0243] In some embodiments, Figure 10-11 As shown, the recessed portion 107 includes a first recessed portion and a second recessed portion, wherein the first recessed portion is formed by the main body housing 106 being recessed inwardly from the second side wall 102, and the second recessed portion is formed by the outer wall of the high-voltage accessory housing 140B being recessed inwardly. The main body housing 106 and the high-voltage accessory housing 140B together form a receiving space for receiving the battery pack 13, and the receiving space is the recessed portion 107.

[0244] In some embodiments, Fig. 14B As shown, the bottom of the front side wall of the high-pressure accessory housing 140B has an inverted U-shaped opening 1401B, and the opening 1401B exposes a portion of the high-pressure inflation hose 113, making it convenient for the user to take out the high-pressure inflation hose 113 from the opening 1401B.

[0245] In some embodiments, Fig.14A and Fig. 14C As shown, the high-voltage accessory housing 140B is provided with an insertion port 143B for installing or removing the battery pack 13, and the high-voltage accessory storage slot 141B is arranged opposite to the insertion port 143B in the front-to-back direction. Optionally, the insertion port 143B is formed by a second recessed portion penetrating the bottom surface of the high-voltage accessory housing 140B in the up-down direction.

[0246] In some embodiments, Fig. 14C As shown, at least one second high-voltage accessory storage groove 1411B is extended along the front-to-back direction.

[0247] In some embodiments, Fig. 14C As shown, a fixing part (not shown) is provided in the second high-voltage accessory storage groove 1411B. The fixing part can be integrally formed with the high-voltage accessory housing 140B or can be detachably connected to the high-voltage accessory housing 140B. Other high-voltage accessory heads 114, 115 are installed on the fixing part for easy taking.

[0248] In some embodiments, Fig.14A As shown, a protective pad 16 is also provided on the bottom surface of the high-voltage accessory housing 140B, and the protective pad 16 partially protrudes from the bottom surface of the high-voltage accessory housing 140B. When the portable charging and suction pump is placed on the ground or other surfaces, it is connected to the ground or other surfaces through the protective pad 16, thereby preventing debris on the ground or other surfaces from damaging the components in the high-voltage accessory housing 140B.

[0249] In some embodiments, in order to further fully utilize the internal space of the portable charging and suction pump, without increasing the structural size of the portable charging and suction pump 100, as shown in FIG. Figure 1 and Fig.15 As shown, the low-pressure accessory storage portion 14A includes a low-pressure accessory housing 140A and a low-pressure accessory storage groove. The low-pressure accessory housing 140A is recessed toward the accommodating cavity 105 to form at least one low-pressure accessory storage groove.

[0250] In some embodiments, Figure 16-Figure 17 As shown, a second gap space 17 is formed between the inner wall of the main housing 106 and the low-pressure module 12 , and the low-pressure accessory storage portion 14A is at least partially accommodated in the second gap space 17 .

[0251] Specifically, the main housing 106 has an open upper end surface 106A and a lower end surface 106B, the accommodating cavity 105 is connected with the upper end and the lower end, and the low-voltage accessory storage portion 14A extends into the second gap space 17 through the open upper end surface 106A.

[0252] In some embodiments, Fig.15As shown, the low-pressure accessory storage slot includes a first low-pressure accessory storage slot 142A for accommodating the low-pressure inflatable and inhalable hose 122 and second low-pressure accessory storage slots 143A, 144A, 145A for accommodating other low-pressure inflatable and inhalable components 123, 124, 125, respectively. The low-pressure inflatable and inhalable hose 122 can be detachably connected to the low-pressure air inlet opening 180 or the low-pressure air outlet opening 1042, so as to facilitate the connection between the low-pressure module 12 and the external inflatable and inhalable items. The external object to be inflated is connected to the low-pressure air outlet opening 1042 through the low-pressure air-inflating and air-inhaling hose 122, and the external air is filled into the external object to be inflated through the impeller; conversely, the external object to be inflated is connected to the low-pressure air inlet opening 180 through the low-pressure air-inflating and air-inhaling hose 122, so that the external object to be inflated can be evacuated; other low-pressure air-inflating and air-inhaling accessories 123, 124, and 125 can be connected to one end of the low-pressure air-inflating and air-inhaling hose 122 to adapt to different inflation interfaces.

[0253] In some embodiments, Fig.17 As shown, the second low-pressure accessory storage grooves 143A, 144A, 145A extend into the second gap space 17 through the open upper end surface 106A.

[0254] In some embodiments, Fig.15 As shown, a through opening 146A is provided at a substantially central position of the low-pressure accessory housing 140A for the air inlet pipe 1210 to pass through, and the low-pressure accessory storage groove at least partially surrounds the through opening 146A.

[0255] In some embodiments, the low-pressure module 12 includes an air vent disposed on the portable charging and suction pump 100 for circulation of low-pressure gas, and the low-pressure accessory storage slot at least partially surrounds the air vent.

[0256] In some embodiments, Fig.15 As shown, the first low-pressure accessory storage groove 142A at least partially surrounds the through-port 146A and is arranged at the rear side of the low-pressure accessory housing 140A, and the second low-pressure accessory storage grooves 143A, 144A, and 145A are arranged side by side at the front side of the low-pressure accessory housing 140A. The fan housing 121 includes a circular portion, and the central extension axis X of the air inlet pipe 1210 is arranged at the center of the circle. The upper surface of the fan housing 121 extends upward to the cylindrical space formed by the end of the air inlet pipe 1210, which becomes an available space. At least part of the low-pressure accessory storage groove is arranged in the cylindrical space, and the space on the upper part of the fan housing 121 is fully utilized, so that the low-pressure accessory storage part 14A is close to the low-pressure module 12, and the distance between the low-pressure accessory storage part 14A and the low-pressure module 12 is shortened to the shortest, and the arrangement is more compact.

[0257] In some embodiments, Fig.18A and Fig.18BAs shown, at least part of the low-pressure charging and suction accessories overlap at least partly with the battery pack 13 in the up and down direction, so that the low-pressure charging and suction accessories are arranged closely to the battery pack, and the arrangement is more compact.

[0258] In some embodiments, Fig.18A and Fig.18B As shown, the low-pressure charging and suction hose 122 and the battery pack 13 are both arranged at the rear of the portable charging and suction pump 100, and at least part of the low-pressure charging and suction hose 122 and the battery pack 13 overlap at least partly in the up and down direction.

[0259] In some embodiments, in order to avoid the low-pressure inflator accessories being exposed and easily lost or causing the appearance of the whole machine to be unsightly, such as Fig.15 As shown, a cover 18 is connected to the low-pressure accessory housing 140A, and the low-pressure accessory housing 140A and the cover 18 can be pivotally connected or connected by a buckle structure, which is not limited here. In this embodiment, the low-pressure accessory housing 140A and the cover 18 can be pivotally connected. If the user needs to take the low-pressure inflatable and inhalable accessories, the cover 18 is pivotally opened to take them. After use, the low-pressure inflatable accessories are stored in the low-pressure accessory storage portion 14A, and the cover 18 is closed.

[0260] Optionally, the cover 18 is made of a transparent or translucent material, and the user can check the status of the low-pressure charging and suction accessories in the low-pressure accessory storage portion 14A when the cover 18 is closed.

[0261] Alternatively, if Figure 1 , Figure 8 and Fig.15 As shown, a low-pressure air inlet opening 180 is provided on the cover 18 at a position corresponding to the through-opening 146A, and the air inlet pipe 1210 passes through the through-opening 146A and extends to the low-pressure air inlet opening 180 .

[0262] Optional, such as Figure 1 and Figure 8 As shown, when the cover 18 is in the closed state, the end of the air inlet pipe 1210 is flush with the upper surface of the cover 18.

[0263] In some embodiments, in order to prevent the high-pressure inflation accessories from being exposed and easily lost or causing the overall appearance of the device to be unsightly, a cover is connected to the high-pressure accessory housing 140B. The high-pressure accessory housing 140B and the cover can be pivotally connected or connected by a snap-fit ​​structure, which is not limited here.

[0264] In some embodiments, Figure 1 and Fig.15 As shown, a handle 15 is also pivotally mounted on the low-voltage accessory housing 140A. In other embodiments, the handle 15 can also be pivotally mounted on the main housing 106.

[0265] In some embodiments, Figure 1 As shown, the portable charging and suction pump 100 further includes a lighting module (not shown). The lighting module includes a light-emitting member 1043 connected to the battery pack 13, and the second side wall 102 of the main body housing 106 has a mounting opening adapted to the shape of the light-emitting member 1043. The light-emitting member 1043 is mounted on the mounting opening to emit light, thereby realizing the lighting function of the portable charging and suction pump and increasing the practical function of the portable charging and suction pump.

[0266] In the present application, the portable inflatable pump 100 at least includes a high-voltage module, a low-voltage module, an inflatable accessory and a battery pack. First, by designing the layout between the high-voltage module and the low-voltage module, space is saved in the length, width and height directions respectively; secondly, by further arranging the battery pack, space is further saved in the length, width and height directions, so as to achieve the purpose of compact and miniaturized structure of the portable inflatable pump; finally, the remaining space inside the portable inflatable pump is fully utilized to layout the inflatable accessories, saving the space occupied by the accessories when they are stored. In this way, the compactness between the modules installed on the outer shell of the portable inflatable pump is maximized, so that the portable inflatable pump not only meets the requirements of multi-functions, but also achieves miniaturization and high space utilization.

[0267] like Figure 1 and Fig.19 As shown, the size miniaturization of the portable charging and suction pump in the present application can reach the following parameters: the range of length L reaches 150mm~200mm; the range of width W reaches 120mm~140mm; the range of height H reaches 175mm~195mm. Under the premise that the outer packaging of the portable charging and suction pump does not exceed 6L, the power of the first motor in the present application is between 120-170W, the power of the second motor is between 60-90W, the time required for the high-pressure module to fill a 215 / 55R17 tire (tire pressure value from 0 to 2.5bar) is 4min, and the inflation flow rate of the low-pressure module is 5-6L / s. In order to ensure the compact structure of the portable charging and suction pump, the present invention improves the space utilization rate through the reasonable layout of the various components of the whole machine, and realizes the miniaturization of the whole volume of the portable charging and suction pump without sacrificing function and performance, so that the whole portable charging and suction pump is in a relatively reasonable size.

[0268] In order to diversify the functions of the portable charging and suction pump and apply it to different scenarios, the portable charging and suction pump includes a high-pressure module and a low-pressure module. Through reasonable layout, the size of the charging and suction assembly formed by the combination of the high-pressure module and the low-pressure module is miniaturized, and the following parameters can be achieved: Fig. 20A and Fig. 20BAs shown, the length L1 of the filling and suction assembly ranges from 110 mm to 135 mm; the width W1 ranges from 75 mm to 95 mm; and the height H1 ranges from 154 mm to 174 mm.

[0269] The length ratio L:L1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1.1:1 to 1.8:1; the width ratio W:W1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1.3:1 to 1.9:1; the height ratio H:H1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1:1 to 1.3:1. In summary, the present application optimizes the layout of the components of the portable charging and suction pump, so that the portable charging and suction pump has a compact structure.

[0270] In order to make the portable charging and suction pump integrated, the user can use it conveniently. Figure 1 and Figure 2A As shown, the portable charging and suction pump 100 includes an outer shell 10, the outer shell 10 has a receiving chamber 105, and the outer shell 10 extends along the longitudinal axis A in the up and down direction; the portable charging and suction pump 100 also includes a high-pressure module 11, which is received in the receiving chamber 105 and is used to generate high-pressure gas to achieve high-pressure inflation, and a low-pressure module 12, which is also received in the receiving chamber 105 and is used to generate low-pressure gas to achieve low-pressure inflation; the outer shell 10 is provided with a low-pressure outlet opening 1042, a low-pressure inlet opening 180 and a high-pressure outlet opening 1041, and the low-pressure outlet opening 1042 and the low-pressure inlet opening 180 are used to connect low-pressure inflation accessories (such as Fig.15 The low-pressure air inlet and outlet opening 1041 is used to connect the high-pressure air inlet and outlet accessories (such as Fig. 14B The high-pressure inflatable accessories 113, 114, 115 shown in the figure); wherein the low-pressure outlet opening 1042 and the high-pressure outlet opening 1041 are located on the same side of the outer shell 10. The high and low pressure outlet openings are arranged on the same side, and such a layout conforms to the user's operating habits and is convenient for users to use.

[0271] In some embodiments, Figure 1 As shown, the low-pressure gas outlet opening 1042 and the high-pressure gas outlet opening 1041 are arranged in the up-down direction.

[0272] In some embodiments, Figure 1 As shown, the line connecting the center of the low-pressure outlet opening 1042 and the center of the high-pressure outlet opening 1041 is parallel to the longitudinal axis A. With such a layout, space is saved in the front-to-back direction of the outer shell for arranging other components, making good use of the space arrangement.

[0273] Specifically, Figure 1As shown, the line connecting the center of the low-pressure air outlet opening 1042 and the center of the high-pressure air outlet opening 1041 is parallel to the longitudinal axis A, saving space in the front-to-back direction of the outer shell for arranging the first heat dissipation air hole, namely, the air outlet hole 1040 .

[0274] In some embodiments, Figure 1 , Figure 3 and Fig. 9B As shown, the low-pressure module 12 also includes a fan 3, which includes an impeller (not shown), a fan housing 121 for accommodating the impeller, and an air inlet pipe 1210 and an air outlet pipe 1211 connected to the fan housing 121, and the projection of the air outlet pipe 1211 in the vertical direction at least partially overlaps with the projection of the high-pressure air outlet 1111. Optionally, the end of the air outlet pipe 1211 is flush with the end of the high-pressure air outlet 1111.

[0275] In some embodiments, Figure 1 As shown, the end of the air inlet pipe 1210 is connected to or flush with the low-pressure air inlet opening 180; the end of the air outlet pipe 1211 is connected to or flush with the low-pressure air outlet opening 1042; the end of the high-pressure air outlet 1111 is connected to or flush with the high-pressure air outlet opening 1041.

[0276] In some embodiments, Figure 1 As shown, the low-pressure air inlet opening 180 is arranged on the top side of the outer shell 10. Such a layout keeps some dust or debris away from the low-pressure air inlet opening, and will not enter the low-pressure air inlet opening to cause damage to the low-pressure module.

[0277] In some embodiments, Figure 8 As shown, the low-pressure module 12 is at least partially disposed above the high-pressure module 11 , the low-pressure air inlet opening 180 and the low-pressure air outlet opening 1042 are disposed close to the low-pressure module 12 , and the high-pressure air outlet opening 1041 is disposed close to the high-pressure module 11 .

[0278] In some embodiments, Figure 1 and Figure 7 The side surface 104 provided with the low pressure air outlet opening 1042 and the high pressure air outlet opening is provided with a first heat dissipation vent, and the other side surface 103 opposite to the side surface 104 is provided with a second heat dissipation vent. Such a layout makes full use of the side wall of the outer shell to arrange the heat dissipation vents.

[0279] Specifically, Figure 5 , Figure 7 and Figure 8As shown, the high-voltage module 11 further includes a cooling fan 1101 arranged opposite to the high-voltage air outlet 1111. In the left-right direction, the side walls of the outer shell 10 are provided with air inlets and air outlets. Specifically, the third side wall 103 of the outer shell 10 closest to the cooling fan is provided with a first cooling air hole, i.e., the air inlet 1030. Correspondingly, the fourth side wall 104 opposite to the third side wall 103 is provided with a second cooling air hole, i.e., the air outlet 1040. The first motor 110 drives the cooling fan 1101 to rotate, and the cooling air flows in from the air inlet 1030, dissipates the heat of the first motor 110 and the cylinder assembly 111, and then flows out from the air outlet 1040.

[0280] In some embodiments, the distance between the cooling fan 1101 and the side wall of the outer shell 10 closest to the cooling fan does not exceed 20 mm. This configuration reduces the distance between the cooling fan and the side wall of the outer shell as much as possible, further utilizing the space and achieving a compact structure.

[0281] In the implementation mode of the present application, Figure 8 As shown, the cooling fan 1101 is disposed close to the third side wall 103, and the distance between the third side wall 103 of the outer shell 10 closest to the cooling fan 1101 is no more than 20 mm.

[0282] In order to make the portable charging and suction pump integrated, the user can use it conveniently. Figure 1 As shown, a portable charging and suction pump includes an outer shell 10, the outer shell 10 has a receiving chamber 105, and the outer shell 10 extends along the longitudinal axis A in the up-down direction; the portable charging and suction pump 100 also includes a high-pressure module 11, which is received in the receiving chamber 105 and is used to generate high-pressure gas to achieve high-pressure inflation, and a low-pressure module 12, which is also received in the receiving chamber 105 and is used to generate low-pressure gas to achieve low-pressure inflation; the portable charging and suction pump 100 also includes a high-pressure accessory storage part 14B and a low-pressure accessory storage part 14A, and the high-pressure accessory storage part 14B and the low-pressure accessory storage part 14A respectively include a movably arranged cover and a storage slot closed by the cover. Such a layout allows the accessories to be accommodated in the storage slot, reducing the space occupied by the accessories, and the storage slot is closed by the cover to prevent the accessories from being lost or dust.

[0283] Specifically, Figures 14A-14CAs shown, the high-pressure accessory storage portion 14B includes a high-pressure accessory housing 140B and a high-pressure accessory storage slot 141B, and the high-pressure accessory housing 140B is recessed toward the receiving chamber 105 to form at least one high-pressure accessory storage slot 141B. The high-pressure accessory storage slot 141B includes a first high-pressure accessory storage slot 1410B for accommodating a high-pressure inflation hose 113 and a second high-pressure accessory storage slot 1411B for accommodating other high-pressure inflation accessories, wherein the high-pressure inflation hose 113 can be detachably connected to the high-pressure inflation opening 1041 of the high-pressure assembly 11, thereby facilitating the high-pressure module 11 to be connected to an external object to be inflated for high-pressure inflation. The first high-pressure accessory storage groove 1410B surrounds the second high-pressure accessory storage groove 1411B, and the first high-pressure accessory storage groove 1410B partially extends along the four sides of the bottom surface of the high-pressure accessory housing 140B. Since the first high-pressure accessory storage groove 1410B is used to store the longer high-pressure inflation hose 113, through such a design, the high-pressure inflation accessories can be reasonably arranged in the high-pressure accessory storage part without taking up too much space.

[0284] Specifically, Fig.15 As shown, the low-pressure accessory storage slot includes a first low-pressure accessory storage slot 142A for accommodating the low-pressure inflatable and inhalable hose 122 and second low-pressure accessory storage slots 143A, 144A, 145A for accommodating other low-pressure inflatable and inhalable components 123, 124, 125, respectively. The low-pressure inflatable and inhalable hose 122 can be detachably connected to the low-pressure air inlet opening 180 or the low-pressure air outlet opening 1042, so as to facilitate the connection between the low-pressure module 12 and the external inflatable and inhalable items. The low-pressure air inhalation hose 122 is used to connect the external inflatable object to the low-pressure air outlet opening 1042, and the external air is filled into the external inflatable object through the impeller; conversely, the external inflatable object is connected to the low-pressure air inlet opening 180 through the low-pressure air inhalation hose 122, and the external inflatable object can be evacuated; other low-pressure inflatable accessories 123, 124, 125 can be connected to one end of the low-pressure air inhalation hose 122 to adapt to different inflatable interfaces. The low-pressure accessory housing 140A has a through hole 146A at the approximate center position for the air inlet pipe 1210 to pass through, and the low-pressure accessory storage groove at least partially surrounds the through hole 146A.

[0285] The first low-pressure accessory storage groove 142A at least partially surrounds the through-port 146A and is arranged at the rear side of the low-pressure accessory housing 140A, and the second low-pressure accessory storage grooves 143A, 144A, and 145A are arranged side by side at the front side of the low-pressure accessory housing 140A. The fan housing 121 is roughly circular, and the central extension axis X of the air inlet pipe 1210 is arranged at the center of the circle. The upper surface of the fan housing 121 extends upward to the cylindrical space formed by the end of the air inlet pipe 1210, which becomes an available space. At least part of the low-pressure accessory storage groove is arranged in the cylindrical space, making full use of the space on the upper part of the fan housing 121, so that the low-pressure accessory storage part 14A is close to the low-pressure module 12, and the distance between the low-pressure accessory storage part 14A and the low-pressure module 12 is shortened to the shortest, and the arrangement is more compact.

[0286] In some embodiments, Figure 1 and Figure 7 As shown, the high-pressure accessory storage part 14B is arranged near the high-pressure module 11, and the low-pressure accessory storage part 14A is arranged near the low-pressure module 12. The cover (not shown) of the high-pressure accessory storage part 14B is located at the bottom of the portable charging and suction pump 100, and the cover 18 of the low-pressure accessory storage part 14A is located at the top of the portable charging and suction pump. With such a layout, the user can take the accessories in the accessory storage part when operating the high and low pressure modules.

[0287] In some embodiments, Figure 1 As shown, the portable charging and suction pump 100 also includes a user operation interface 1010, which is arranged on the outer shell 10 between the high-pressure accessory storage part 14B and the low-pressure accessory storage part 14A. The user operation interface 1010 includes operating elements for controlling the high-pressure module 11 and the low-pressure module 12.

[0288] Specifically, Figure 1 and Figure 1A As shown, the portable charging and suction pump 100 also includes a user operation interface 1010, which is arranged on the first side wall 101, and the operating elements include a display screen 1010A, a control button 1010B and a knob 1010C for adjusting the pressure value, which are connected to the control mainboard signal. The control mainboard is signal-connected to the charging and suction component and the lighting module (not shown), so that the control button 1010B can be used to control the opening and closing of the charging and suction component and the lighting module, and the pressure value can be adjusted by the knob 1010C. The current status information of the charging and suction component and the lighting module can be displayed in real time through the display screen 1010A, thereby realizing automatic control of the portable charging and suction pump.

[0289] In some embodiments, Fig.16As shown, along the vertical projection, the high-pressure accessory storage portion 14B and the low-pressure accessory storage portion 14A are within the projection range of the outer shell 10. Such a layout prevents the accessory storage portion from protruding out of the outer shell contour, and the portable charging and suction pump is integrated and has a neat appearance.

[0290] In some embodiments, Fig.10 and Fig.11 As shown, the portable charging and suction pump 100 has a battery pack mounting portion 130 for detachably mounting the battery pack 13. When projected in the up-down direction, the battery pack 13 is within the projection range of the outer shell 10. Such a layout prevents the battery pack from protruding from the outer shell contour, and the portable charging and suction pump is integrated and has a neat appearance.

[0291] In order to make the layout of the portable charging and suction pump more compact in the vertical direction (i.e., in the height direction), the space saved in the height direction of the outer shell can be used for the arrangement of other components, such as Figure 1 , Figure 1A and Figure 1B As shown, the portable charging and suction pump is placed on a horizontal plane as a reference diagram, wherein the direction perpendicular to the horizontal plane is the up-down direction, i.e., the height direction of the portable charging and suction pump. The portable charging and suction pump 100 includes an outer shell 10, the outer shell 10 has a receiving cavity 105, and the outer shell 10 extends along a longitudinal extension axis A in the up-down direction (i.e., the height direction). The portable charging and suction pump 100 also includes a high-pressure module 11 received in the receiving cavity 105 to realize high-pressure inflation, and the high-pressure module 11 includes a first motor axis C (such as Figure 8 The invention relates to a first motor 110 (as shown) for rotating, and a cylinder assembly 111 connected to the first motor 110, wherein the cylinder assembly 111 comprises a piston (not shown) and a cylinder body 1110; the first motor 110 drives the piston to reciprocate along a central extension axis B in the cylinder body 1110 to achieve high-pressure inflation; wherein the central extension axis B intersects with a longitudinal extension axis A of the outer shell 10, and an intersection angle α is an acute angle or an obtuse angle.

[0292] The central extension axis B intersects with the longitudinal extension axis A, and the intersection angle α is an acute angle or an obtuse angle. Such a layout allows the cylinder assembly of the high-pressure module to be placed at an angle in the outer shell, and the layout of the portable charging and suction pump in the up and down directions (i.e., the height direction) is more compact, so that the space in the height direction of the outer shell can be saved for the arrangement of other components, further making the portable charging and suction pump have high space utilization and compact structure.

[0293] In some embodiments, Figure 1As shown, the outer shell 10 of the portable charging and suction pump 100 can be generally in the shape of a hollow cuboid, and the edges between adjacent surfaces of the outer shell 10 can have smooth chamfers, so that the volume of the outer shell 10 is reduced and more beautiful. The outer shell 10 may include a first side wall 101 and a second side wall 102 opposite to each other, and the first side wall 101 and the second side wall 102 are arranged in the front-to-back direction perpendicular to the up-down direction (i.e., the width direction of the portable charging and suction pump); a third side wall 103 and a fourth side wall 104 opposite to each other, and the third side wall 103 and the fourth side wall 104 are arranged in the left-right direction perpendicular to the up-down direction (i.e., the length direction of the portable charging and suction pump). The outer shell 10 includes a main body shell 106, and the main body shell 106 has an upper end face 106A and a lower end face 106B, and the main body shell 106 also extends along the longitudinal extension axis A in the up-down direction (i.e., the height direction).

[0294] In some embodiments, Figure 1B As shown, the central extension axis B intersects with the longitudinal extension axis A at an acute angle α, the acute angle α ranges from 10° to 80°, optionally, the acute angle α ranges from 15° to 50°, and in this embodiment, the acute angle α is 25°; the central extension axis B and the longitudinal extension axis A may also intersect at an obtuse angle β, the obtuse angle β ranges from 100° to 170°, optionally, the obtuse angle β ranges from 130° to 165°, and in this embodiment, the obtuse angle β is 155°, wherein the acute angle α and the obtuse angle β are complementary angles. Such an arrangement allows the cylinder assembly to be tilted in the outer shell, and the tilt angle can be adjusted between the minimum angle and the maximum angle according to the arrangement of other components, so that the portable charging and suction pump not only saves space in the up and down direction (i.e., the height direction), but also maximizes the space utilization.

[0295] In some embodiments, Figure 3 As shown, the high-pressure module 11 further includes a high-pressure gas outlet 1111 for discharging high-pressure gas, and the distance between the side wall of the outer shell 10 closest to the high-pressure gas outlet 1111 does not exceed 20 mm. In this way, the distance between the high-pressure gas outlet and the side wall of the outer shell is reduced as much as possible, further utilizing the space and achieving the purpose of compact structure.

[0296] In the implementation mode of the present application, Figure 1 and Figure 3 As shown, the high-pressure air outlet 1111 corresponds to the position of the high-pressure air outlet opening 1041 on the outer shell 10, and the high-pressure air outlet opening 1041 is arranged on the fourth side wall 104, and the distance between the fourth side wall 104 of the outer shell 10 closest to the high-pressure air outlet 1111 does not exceed 20 mm.

[0297] In some embodiments, Figure 1CAs shown, the high-voltage module 11 also includes a transmission assembly 112 arranged between the first motor 110 and the cylinder assembly 111. The first motor 110 and the transmission assembly 112 are supported on a fixed bracket (not shown). The transmission assembly 112 connects the piston rod 1112 and the output shaft of the first motor 110 (not shown). The transmission assembly 112 converts the rotational motion of the output shaft of the first motor 110 into linear motion to transmit it to the piston rod 1112.

[0298] Specifically, the transmission assembly 112 includes a transmission member and an eccentric wheel 1123. In the embodiment of the present application, the transmission member is a gear set, and the gear set includes a driving wheel 1121 and a driven wheel 1122. The driving wheel 1121 of the gear set is installed on the output shaft of the first motor 110. In other embodiments, the transmission member can also be set to other, such as rack transmission, chain transmission, connecting rod transmission, belt transmission, etc., which are not specifically limited here and are determined according to actual conditions. The eccentric wheel 1123 is connected to the driven wheel 1122 in the gear set, and the eccentric wheel 1123 is driven by the driven wheel 1122 to rotate in a circle. The piston rod 1112 is connected to the eccentric wheel 1124, and the piston rod 1112 is pushed by the eccentric wheel 1123 to make reciprocating linear motion. When the gear set drives the piston rod 1112 to move toward the direction close to the high-pressure air outlet 1111, the volume of the gas compressed and accumulated in the cylinder 1110 becomes smaller, and the cylinder 1110 is connected to the high-pressure air outlet 1111 through the three-way joint 1113. The gas generated by the cylinder 1110 can be transported to the equipment to be inflated along the high-pressure inflation hose 113.

[0299] In some embodiments, Figure 1C As shown, the high-pressure module 11 also includes a three-way joint 1113 connected to the cylinder body 1110, and the three-way joint 1113 is connected to the high-pressure gas outlet 1111; the first motor 110 drives the piston to reciprocate along the central extension axis B in the cylinder body 1110 to achieve high-pressure inflation, and discharges the compressed gas through the high-pressure gas outlet 1111 connected to the three-way joint 1113.

[0300] In some embodiments, Figure 1C As shown, the first end of the three-way connector 1113 is connected to the air outlet of the cylinder 1110, the second end is connected to the high-pressure air outlet 1111, and the third end is connected to an air pressure sensor (not shown). The air pressure sensor monitors the air pressure value in real time and compares it with the target air pressure value. When the target air pressure value is exceeded, inflation is stopped, thereby realizing automatic control of the portable inflation and suction pump.

[0301] In some embodiments, Figure 1C As shown, the cylinder body 1110 and the fixing bracket are of die-cast integrated design, and a reinforcing rib 1114 is provided at the junction of the cylinder body 1110 and the fixing bracket.

[0302] In some embodiments, Figure 1C As shown, the high voltage module 11 further includes a first motor housing 110A, 110B, and the first motor housing 110A, 110B covers the first motor 110 and is fixedly installed in the receiving cavity 105 .

[0303] In some embodiments, Figure 5 and Figure 6 As shown, a vibration damping ring 1102 is provided at an end of the first motor 110 away from the high-pressure air outlet 1111, and the vibration damping ring 1102 is arranged between the first motor housing 110A, 110B and the first motor 110. Furthermore, at an end of the first motor 110 close to the high-pressure air outlet 1111, vibration damping pads 1103A, 1103B are provided between the fixed bracket and the first motor housing 110A, 110B.

[0304] In some embodiments, Figure 1A and Figure 7 As shown, the high-voltage module 11 further includes a cooling fan 1101 arranged opposite to the high-voltage air outlet 1111. In the left-right direction, the side walls of the outer shell 10 are provided with air inlets and air outlets. Specifically, the third side wall 103 of the outer shell 10 closest to the cooling fan is provided with an air inlet 1030, and correspondingly, the fourth side wall 104 opposite to the third side wall 103 is provided with an air outlet 1040. The first motor 110 drives the cooling fan 1101 to rotate, and the cooling air flows in from the air inlet 1030, dissipates the heat of the first motor 110 and the cylinder assembly 111, and then flows out from the air outlet 1040.

[0305] In some embodiments, the distance between the cooling fan 1101 and the side wall of the outer shell 10 closest to the cooling fan does not exceed 20 mm. This configuration reduces the distance between the cooling fan and the side wall of the outer shell as much as possible, further utilizing the space and achieving a compact structure.

[0306] In the implementation mode of the present application, Figure 8 As shown, the heat dissipation fan 1101 is disposed close to the third side wall 103 , and the distance between the third side wall 103 of the outer shell 10 closest to the heat dissipation fan 1101 does not exceed 20 mm.

[0307] In some embodiments, Figure 2A and Figure 8 As shown, in order to diversify the functionality of the portable charging and suction pump and meet the application of different operating scenarios of users, the portable charging and suction pump 100 also includes a low-pressure module 12, which is accommodated in the accommodating cavity 105, including a second motor 120 rotating around the second motor axis D, and a fan connected to the second motor 120, and the second motor 120 drives the fan to rotate to achieve low-pressure charging and suction.

[0308] Specifically, Figure 1 and Figure 3 As shown, the low-pressure module 12 includes a second motor 120, a fan connected to the second motor 120, and an air outlet arranged on the portable charging and suction pump. The fan 3 includes an impeller (not shown), a fan housing 121 for accommodating the impeller, and an air inlet pipe 1210 and an air outlet pipe 1211 connected to the fan housing 121. The air inlet pipe 1210 and the air outlet pipe 1211 correspond to the air outlet position on the portable charging and suction pump 100. The impeller is arranged on the output shaft of the second motor 120. The second motor 120 can drive the impeller to rotate, and the low-pressure gas flows, thereby inflating or exhausting the external objects connected to the low-pressure module 12.

[0309] In some embodiments, Figure 3 and Figure 8 As shown, the second motor axis D extends in the up-down direction and is arranged parallel to the longitudinal extension axis of the outer shell 10, that is, the second motor 120 is vertically placed in the accommodating cavity, thereby utilizing the space in the up-down direction (that is, the height direction) in the outer shell 10 to arrange the low-voltage module 12.

[0310] In some embodiments, Figure 3 and Figure 8 As shown, the air inlet pipe 1210 has a central extension axis X, and the air outlet pipe 1211 has a central extension axis Y. In the embodiment of the present application, the central extension axis X is arranged parallel to the second motor axis D, and the central extension axis Y is arranged perpendicular to the second motor axis D. Optionally, the central extension axis X coincides with the second motor axis D. In other embodiments, the central extension axis X is arranged perpendicular to the second motor axis D, and the central extension axis Y is arranged parallel to the second motor axis D. Optionally, the central extension axis Y coincides with the second motor axis D.

[0311] In some embodiments, Figure 8 As shown, the first motor 110 of the high-voltage module 11 has a first motor axis C extending in the left-right direction, that is, the first motor 110 is horizontally placed in the accommodating cavity 105, thereby utilizing the space in the left-right direction (i.e., the length direction) in the outer shell 10 to arrange the high-voltage module 11.

[0312] In some embodiments, Figure 8 As shown, the first motor axis C is arranged perpendicular to the second motor axis D.

[0313] In some embodiments, Figure 4A As shown, the first motor 110 drives the piston to reciprocate along the central extension axis B in the cylinder 1110 , and the central extension axis B is arranged at an angle with the second motor axis D, and the angle is an acute angle or an obtuse angle.

[0314] In some embodiments, Figure 8 As shown, the second motor 120 of the low-voltage module 12 is placed at an upper position in the outer shell 10 in the up-down direction relative to the first motor 110, and the space between the second motor 120 and the lower end of the outer shell 10 is used to place the first motor 110, and the first motor 110 is placed at a lower position in the outer shell 10 in the up-down direction relative to the second motor 120.

[0315] In addition to utilizing space for arrangement, the overall position of the high-pressure module 11 is set at a lower position of the outer shell 10 relative to the low-pressure module 12, so that the center of gravity of the portable charging and suction pump 100 is lower, which makes it more stable when the user operates it. At the same time, since the high-pressure module 11 will generate vibrations, if it is placed in a higher position, it will cause the portable charging and suction pump 100 to shake during use, which is inconvenient for the user to operate.

[0316] In order to further make full use of the space in the outer shell 10 to accommodate the charging and suction components, the portable charging and suction pump 100 is miniaturized. Fig.9A and Fig. 9B As shown, the high-pressure module 11 and the low-pressure module 12 at least partially overlap in the up-down direction, so that the portable charging and suction pump 100 makes full use of the space for arrangement, achieving the purpose of miniaturization.

[0317] In some embodiments, Fig.9A and Fig. 9B As shown, the fan 3 at least partially overlaps with at least one of the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the up and down direction, thereby saving space in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction) of the portable charging and suction pump 100.

[0318] In the implementation mode of the present application, Figure 3 and Fig.9A As shown, the fan 3 of the low-pressure module 12 at least partially overlaps with the first motor 110, the cylinder assembly 111 and the transmission assembly 112 in the upper and lower directions. Since the fan casing 121 is roughly circular, the second motor axis D is arranged at the center of the circle, and the cylindrical space formed by the lower surface of the fan casing 121 extending downward to the end of the second motor 120 becomes a usable space. At least part of the high-pressure module 11 is arranged below the fan casing 121 or the impeller, and the lower space of the fan casing 121 or the impeller is fully utilized, so that the low-pressure module 12 and the high-pressure module 11 are close to each other and the arrangement is more compact.

[0319] In some embodiments, Figure 3 and Fig.9AAs shown, the second motor 120 drives the impeller to rotate and discharge low-pressure gas from the air outlet pipe 1211. The air outlet pipe 1211 and the cylinder assembly 111 at least partially overlap in the vertical direction, so that the space below the air outlet pipe 1211 is used to arrange the cylinder assembly 111.

[0320] Optionally, the air outlet pipe 1211 and the cylinder assembly 111 are both disposed close to the third side wall 103 or the fourth side wall 104 of the outer shell 10 .

[0321] In some embodiments, Figure 1 As shown, the outer shell 10 of the portable charging and suction pump 100 is provided with an air vent for the circulation of low-pressure gas, and the air vent and the high-pressure gas outlet opening 1041 are located on the same side of the outer shell 10 .

[0322] In the implementation mode of the present application, Figure 1 , Figure 3 and Fig. 9B As shown, the air outlet includes a low-pressure air outlet opening 1042 and a low-pressure air inlet opening 180 , which are respectively connected to the air outlet pipe 1211 and the air inlet pipe 1210 for the circulation of low-pressure gas. The low-pressure air outlet opening 1042 and the high-pressure air outlet opening 1041 are located on the same side of the outer shell 10 .

[0323] Optionally, the air outlet pipe 1211 and the high-pressure air outlet 1111 at least partially overlap in the up-down direction.

[0324] Optionally, the end of the air outlet pipe 1211 is flush with the end of the high-pressure air outlet 1111 .

[0325] In some embodiments, Fig. 9B As shown, the second motor 120 at least partially overlaps with at least one of the first motor 110, the cylinder assembly 111, and the transmission assembly 112 in the up and down direction, thereby saving space in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction) of the portable charging and suction pump 100.

[0326] In the implementation mode of the present application, Fig. 9B As shown, the second motor 120 at least partially overlaps with the first motor 110 in the up and down direction.

[0327] In order to further make full use of the space in the outer shell 10 to accommodate the charging and suction components, the portable charging and suction pump 100 is miniaturized. Figure 4A As shown, the high-pressure module 11 and the low-pressure module 12 at least partially overlap in the left-right direction, so that the portable charging and suction pump 100 fully utilizes the space in the up-down direction (ie, the height direction) for arrangement, achieving the purpose of miniaturization.

[0328] In some embodiments, the fan 3 at least partially overlaps with at least one of the first motor 110 , the cylinder assembly 111 , and the transmission assembly 112 in the left-right direction.

[0329] In some embodiments, the second motor 120 at least partially overlaps with at least one of the first motor 110 , the cylinder assembly 111 , and the transmission assembly 112 in the left-right direction.

[0330] In the implementation mode of the present application, Figure 4A As shown, the second motor 120 and the cylinder assembly 111 at least partially overlap in the left-right direction, so that the portable charging and suction pump 100 saves space in the up-down direction (ie, the height direction).

[0331] In order to facilitate the user to use the portable charging and suction pump 100, so that the portable charging and suction pump 100 can be used in any position without restriction, the portable charging and suction pump 100 includes a battery pack 13 for powering the portable charging and suction pump. Figure 10-11 As shown, in the front-to-back direction, the battery pack 13 is disposed on one side of the outer shell 10. The battery pack 13 is detachably mounted on the outer shell 10 in the up-down direction.

[0332] Disposing the battery pack 13 on one side of the outer shell 10 can make the battery pack 13 close to the high-voltage module 11 or the low-voltage module 12, and reduce the distance between the battery pack 13 and the high-voltage module 11 or the low-voltage module 12, so that the portable charging and suction pump can be more compact while ensuring its performance.

[0333] In some embodiments, Fig.10 and Fig.11 As shown, the outer shell 10 is provided with a battery pack mating portion 130, and the battery pack 13 is slidably matched with the battery mating portion 130 when installed, and the sliding direction of the battery pack 13 is parallel to the longitudinal extension direction of the outer shell 10. Further, when the battery pack 13 is assembled, it slides toward the upper end surface 106A of the main body shell 106, and further, the battery pack 13 slides from the lower end surface 106B of the main body shell 10 toward the upper end surface 106A. Such a configuration facilitates the charging of the battery pack 13, and facilitates the application of the battery pack 13 to other matching power tools or the portable charging and suction pump using the battery pack 13 of other matching power tools, that is, multiple machines can share one battery pack 13, saving costs.

[0334] In an embodiment of the present application, the battery pack 13 is vertically mounted on one side of the outer shell 10 . In other embodiments, the battery pack 13 can be placed horizontally at different positions of the portable charging and suction pump, or can be vertically mounted at other positions of the outer shell 10 .

[0335] In some embodiments, Figures 10 to 12As shown, one side of the outer shell 10 has a recessed portion 107, and the battery pack 13 is at least partially accommodated in the recessed portion 107. Thus, a part of the space of the outer shell 10 is used to accommodate the battery pack 13, and the space utilization rate of the whole device is high, the volume is small, and it is easy to carry.

[0336] Optionally, the overall shape of the battery pack 13 is similar to the recessed portion 107 , so that the battery pack 13 can be installed in the recessed portion 107 under the premise of maximization, and the space at the second side wall 102 of the outer shell 10 will not be wasted.

[0337] Optionally, the width of the entire recessed portion 107 in the front-to-back direction is smaller than the height in the up-down direction, so that the width of the outer shell 10 in the front-to-back direction is relatively small, which facilitates the miniaturization of the portable charging and suction pump.

[0338] In some embodiments, when the battery pack 13 is accommodated in the recessed portion 107, the battery pack 13 does not extend beyond the outer shell 10. With such a design, there is no protruding structure on the side wall of the portable charging and suction pump, and when the side wall of the outer shell is used as a support surface, the stability of the placement of the portable charging and suction pump is not affected.

[0339] In the implementation mode of the present application, Fig.12 As shown, specifically, the rear end face of the battery pack 13 does not exceed the second side wall 102 of the outer shell 10, and the left end face and the right end face of the battery pack 13 do not exceed the third side wall 103 and the fourth side wall 104 of the outer shell, respectively.

[0340] In some embodiments, Figure 10 to Figure 11 As shown, the recessed portion 107 extends in the up-down direction and penetrates the lower end surface 106B of the main housing 106 , so that the battery pack 13 can be removed from the lower end surface 106B.

[0341] Optionally, the recessed portion 107 does not penetrate the upper end surface 106A of the host housing 106 , and the recessed portion 107 has a top portion 1070 , which does not exceed the upper end surface 106A of the host housing 106 in the up and down directions.

[0342] When the battery pack 13 is assembled, it is set to slide from the lower end surface 106B toward the upper end surface 106A, and the battery pack 13 can be removed from the lower end surface 106B, which makes it easier to set the upper end surface 106A of the portable charging and suction pump 100 to a complete plane. If the battery pack 13 is inserted by sliding from the upper end surface 106A toward the lower end surface 106B, a gap will inevitably appear on the upper end surface of the main body shell, destroying the integrity of the portable charging and suction pump. The design of this embodiment can solve this problem and ensure the integrity and aesthetics of the appearance of the entire machine.

[0343] In some embodiments, Fig.11As shown, the outer shell 10 has at least one auxiliary gripping portion, and a hollow portion communicating with the recessed portion 107 is formed between the outer shell 10 and the auxiliary gripping portion.

[0344] With such arrangement, when the portable charging and suction pump 100 is not installed with the battery pack 13, the user's hand can pass through the hollow portion and the recessed portion 107 to hold the auxiliary gripping portion to move or operate the portable charging and suction pump.

[0345] In some embodiments, Fig.11 As shown, the auxiliary gripping portion includes a first auxiliary gripping portion 108A and a second auxiliary gripping portion 108B, and a first hollow portion 1044 and a second hollow portion 1034 communicating with the recessed portion 107 are respectively formed between the outer shell 10 and the first auxiliary gripping portion 108A and the second auxiliary gripping portion 108B.

[0346] Optionally, the first auxiliary gripping portion 108A and the second auxiliary gripping portion 108B, and the first hollow portion 1044 and the second hollow portion 1034 are disposed symmetrically.

[0347] Optionally, when the portable charging and suction pump 100 is installed with the battery pack 13 , there is a gap between the battery pack 13 and the right and left sides (not shown) of the recessed portion 107 , and the gap is large enough for the user's hand to pass through.

[0348] In some embodiments, in order to further miniaturize the portable inflation and suction pump, Fig.13A As shown, the battery pack 13 at least partially overlaps with at least one of the high voltage module 11 and the low voltage module 12 in the front-to-back direction, so that the battery pack 13 can reduce the space in the height direction and the length direction after being combined with the high voltage module 11 and the low voltage module 12.

[0349] In some embodiments, Fig.13A As shown, the battery pack 13 is arranged behind the high-voltage module 11 and the low-voltage module 12, and the sliding direction of the battery pack 13 is perpendicular to the first motor axis C and parallel to the second motor axis D. Such an arrangement saves space in the vertical direction (i.e., the height direction) and the left-right direction (i.e., the length direction) between the battery pack 13 and the high-voltage module 11 and the low-voltage module 12, and the arrangement is more compact.

[0350] In some embodiments, Fig. 13B As shown, the battery pack 13 and the low voltage module 12 at least partially overlap in the vertical direction, so that the arrangement between the battery pack 13 and the low voltage module 12 saves space in the front-to-back direction (ie, the width direction).

[0351] In some embodiments, Fig. 13B As shown, the battery pack 13 and the fan housing 121 at least partially overlap in the up and down direction.

[0352] The fan housing 121 is roughly circular, and the second motor axis D is set at the center of the circle. The cylindrical space formed by the lower surface of the fan housing 121 extending downward to the end of the second motor 120 becomes usable space. At least part of the high-voltage module 11 is set under the front half of the fan housing 121, and at least part of the battery pack 13 is set under the rear half of the fan housing 121. The space under the fan housing 121 is fully utilized, so that the battery pack 13 is close to the high-voltage module 11 and the low-voltage module 12, and the distance between the battery pack 13 and the high-voltage module 11 and the low-voltage module 12 is shortened to the shortest, and the arrangement is more compact.

[0353] In some embodiments, the ratio between the height of the portable charging pump 100 and the battery pack 13 is in the range of 1.2:1 to 1.8:1, wherein the height of the portable charging pump is the maximum straight-line distance in the up and down directions, and the height of the battery pack is the straight-line distance between the upper end surface of the battery pack and the lower end surface of the battery pack in the up and down directions.

[0354] In some embodiments, the ratio between the width of the portable charging pump 100 and the battery pack 13 is in the range of 3:1 to 4:1, wherein the width of the portable charging pump is the maximum straight-line distance in the front-to-back direction, and the width of the battery pack is the straight-line distance between the front end face of the battery pack and the rear end face of the battery pack in the front-to-back direction.

[0355] In some embodiments, the ratio between the length of the portable charging pump 100 and the length of the battery pack 13 is in the range of 1.8:1 to 2.4:1, wherein the length of the portable charging pump is the maximum straight-line distance in the left-right direction, and the length of the battery pack is the straight-line distance between the left end face of the battery pack and the right end face of the battery pack in the left-right direction.

[0356] In order to facilitate the connection between the high pressure module 11 and the low pressure module 12 and the external inflatable items, such as Figure 2A As shown, the portable charging and suction pump 100 also includes a low-pressure accessory storage portion 14A for storing low-pressure charging and suction accessories, and a high-pressure accessory storage portion 14B for storing high-pressure charging accessories. The low-pressure accessory storage portion 14A and the high-pressure accessory storage portion 14B are separately arranged in the up and down directions.

[0357] In some embodiments, Figure 1 As shown, the low-pressure accessory storage part 14A and the high-pressure accessory storage part 14B are connected to the main body housing 106, and are separated by the main body housing 106 at both ends in the up and down directions, making full use of the space in the up and down direction (i.e., the height direction) of the portable charging and suction pump 100 to arrange the accessory storage part 14.

[0358] In some embodiments, Figure 2AAs shown, when the user operates the high-voltage module 11 , in order to more conveniently take the high-voltage inflatable accessories, the high-voltage accessory storage portion 14B is disposed close to the high-voltage module 11 .

[0359] In some embodiments, Figure 2A As shown, when the user operates the low-pressure module 12 , in order to more conveniently take the low-pressure charging and suction accessories, the low-pressure accessory storage portion 14A is arranged close to the low-pressure module 12 .

[0360] In some embodiments, Figure 1 , Figure 2A and Figure 8 As shown, relative to the high-pressure module 11, the low-pressure module 12 is vertically placed in the upper position of the main housing 106, and relative to the low-pressure module 12, the high-pressure inflatable gas assembly 11 is horizontally placed in the lower position of the main housing 106. Therefore, the low-pressure accessory storage portion 14A is arranged above the main housing 106 close to the low-pressure module 12, and the high-pressure accessory storage portion 14B is arranged below the main housing 106 close to the high-pressure module 11.

[0361] In some embodiments, in order to further fully utilize the internal space of the portable charging and suction pump, without increasing the structural size of the portable charging and suction pump 100, as shown in FIG. Figure 1 and Figures 14A-14C As shown, the high-voltage accessory storage portion 14B includes a high-voltage accessory housing 140B and a high-voltage accessory storage groove 141B. The high-voltage accessory housing 140B is recessed toward the accommodating cavity 105 to form at least one high-voltage accessory storage groove 141B.

[0362] In some embodiments, a first gap space (not shown) is formed between the inner wall of the main housing 106 and the high voltage module 11 , and the high voltage accessory storage portion 14B is at least partially accommodated in the first gap space.

[0363] Specifically, the main body housing 106 has an open upper end surface 106A and a lower end surface 106B, the receiving cavity 105 is connected with the upper end surface and the lower end surface, and the high-voltage accessory storage portion 14B extends into the first gap space through the open lower end surface 106B.

[0364] In some embodiments, Figure 1 and Figures 14A-14C As shown, the high-pressure accessory storage slot 141B includes a first high-pressure accessory storage slot 1410B for accommodating a high-pressure inflation hose 113 and a second high-pressure accessory storage slot 1411B for accommodating other high-pressure accessory heads, wherein the high-pressure inflation hose 113 can be detachably connected to the high-pressure inflation opening 1041 of the high-pressure module 11, thereby facilitating the connection of the high-pressure module 11 with external inflatable items for high-pressure inflation.

[0365] In some embodiments, at least a portion of the first high-voltage accessory receiving slot 1410B extends through the open lower end surface 106B into the first gap space.

[0366] In some embodiments, the first high-voltage accessory storage slot 1410B surrounds the second high-voltage accessory storage slot 1411B.

[0367] In some embodiments, the first high-pressure accessory storage groove 1410B partially extends along the four sides of the bottom surface of the high-pressure accessory housing 140B. Since the first high-pressure accessory storage groove 1410B is used to store a longer high-pressure inflation hose 113, through such a design, the high-pressure inflation accessories can be reasonably arranged in the high-pressure accessory storage part without taking up too much space.

[0368] In some embodiments, Figure 10-11 As shown, the recessed portion 107 includes a first recessed portion and a second recessed portion, wherein the first recessed portion is formed by the main body housing 106 being recessed inwardly from the second side wall 102, and the second recessed portion is formed by the outer wall of the high-voltage accessory housing 140B being recessed inwardly. The main body housing 106 and the high-voltage accessory housing 140B together form a receiving space for receiving the battery pack 13, and the receiving space is the recessed portion 107.

[0369] In some embodiments, Fig. 14B As shown, the bottom of the front side wall of the high-pressure accessory housing 140B has an inverted U-shaped opening 1401B, and the opening 1401B exposes a portion of the high-pressure inflation hose 113, so that the user can easily insert the high-pressure inflation hose 113 through the opening 1401B.

[0370] In some embodiments, Fig.14A and Fig. 14C As shown, the high-voltage accessory housing 140B is provided with an insertion port 143B for installing or removing the battery pack 13, and the high-voltage accessory storage slot 141B is arranged opposite to the insertion port 143B in the front-to-back direction. Optionally, the insertion port 143B is formed by a second recessed portion penetrating the bottom surface of the high-voltage accessory housing 140B in the up-down direction.

[0371] In some embodiments, Fig. 14C As shown, at least one second high-voltage accessory storage groove 1411B is extended along the front-to-back direction.

[0372] In some embodiments, Fig. 14C As shown, a fixing part (not shown) is provided in the second high-voltage accessory storage groove 1411B. The fixing part can be integrally formed with the high-voltage accessory housing 140B or can be detachably connected to the high-voltage accessory housing 140B. Other high-voltage accessory heads 114, 115 are installed on the fixing part for easy taking.

[0373] In some embodiments, Fig.14AAs shown, a protective pad 16 is also provided on the bottom surface of the high-voltage accessory housing 140B, and the protective pad 16 partially protrudes from the bottom surface of the high-voltage accessory housing 140B. When the portable charging and suction pump is placed on the ground or other surfaces, it is connected to the ground or other surfaces through the protective pad 16, thereby preventing debris on the ground or other surfaces from damaging the components in the high-voltage accessory housing 140B.

[0374] In some embodiments, in order to further fully utilize the internal space of the portable charging and suction pump, without increasing the structural size of the portable charging and suction pump 100, as shown in FIG. Figure 1 and Fig.15 As shown, the low-pressure accessory storage portion 14A includes a low-pressure accessory housing 140A and a low-pressure accessory storage groove. The low-pressure accessory housing 140A is recessed toward the accommodating cavity 105 to form at least one low-pressure accessory storage groove.

[0375] In some embodiments, Figure 16-Figure 17 As shown, a second gap space 17 is formed between the inner wall of the main housing 106 and the low-pressure module 12 , and the low-pressure accessory storage portion 14A is at least partially accommodated in the second gap space 17 .

[0376] Specifically, the main body housing 106 has an open upper end surface 106A and a lower end surface 106B, the accommodating cavity 105 penetrates the upper end surface and the lower end surface, and the low-voltage accessory storage portion 14A extends into the second gap space 17 through the open upper end surface 106A.

[0377] In some embodiments, Fig.15 As shown, the low-pressure accessory storage slot includes a first low-pressure accessory storage slot 142A for accommodating the low-pressure inflatable and inhalable hose 122 and second low-pressure accessory storage slots 143A, 144A, 145A for accommodating other low-pressure inflatable and inhalable components 123, 124, 125, respectively. The low-pressure inflatable and inhalable hose 122 can be detachably connected to the low-pressure air inlet opening 180 or the low-pressure air outlet opening 1042, so as to facilitate the connection between the low-pressure module 12 and the external inflatable and inhalable items. The external object to be inflated is connected to the low-pressure air outlet opening 1042 through the low-pressure air-inflating and air-inhaling hose 122, and the external air is filled into the external object to be inflated through the impeller; conversely, the external object to be inflated is connected to the low-pressure air inlet opening 180 through the low-pressure air-inflating and air-inhaling hose 122, so that the external object to be inflated can be evacuated; other low-pressure air-inflating and air-inhaling accessories 123, 124, and 125 can be connected to one end of the low-pressure air-inflating and air-inhaling hose 122 to adapt to different inflation interfaces.

[0378] In some embodiments, Fig.17 As shown, the second low-pressure accessory storage grooves 143A, 144A, 145A extend into the second gap space 17 through the open upper end surface 106A.

[0379] In some embodiments, Fig.15 As shown, a through opening 146A is provided at a substantially central position of the low-pressure accessory housing 140A for the air inlet pipe 1210 to pass through, and the low-pressure accessory storage groove at least partially surrounds the through opening 146A.

[0380] In some embodiments, the portable charging and suction pump 100 is provided with an air vent for the circulation of low-pressure gas, and the low-pressure accessory storage groove at least partially surrounds the air vent.

[0381] Specifically, Fig.15 As shown, the first low-pressure accessory storage groove 142A at least partially surrounds the through-port 146A and is arranged at the rear side of the low-pressure accessory housing 140A, and the second low-pressure accessory storage grooves 143A, 144A, and 145A are arranged side by side at the front side of the low-pressure accessory housing 140A. The fan housing 121 is roughly a circular portion, and the central extension axis X of the air inlet pipe 1210 is arranged at the center of the circle. The upper surface of the fan housing 121 extends upward to the cylindrical space formed by the end of the air inlet pipe 1210, which becomes an available space. At least part of the low-pressure accessory storage groove is arranged in the cylindrical space, and the space on the upper part of the fan housing 121 is fully utilized, so that the low-pressure accessory storage part 14A is close to the low-pressure module 12, and the distance between the low-pressure accessory storage part 14A and the low-pressure module 12 is shortened to the shortest, and the arrangement is more compact.

[0382] In some embodiments, in order to reduce the size of the portable charging and suction pump 100 in the front-to-back direction (i.e., the width direction) and the left-to-right direction (i.e., the length direction), as shown in FIG. Fig.18A and Fig.18B As shown, the low-pressure air-intake and air-filling accessories 122, 123, 124, 125 at least partially overlap with the high-pressure module 11 or the low-pressure module 12 in the vertical direction. Such an arrangement makes the low-pressure air-intake and air-filling accessories close to the high-pressure module or the low-pressure module, and the arrangement is more compact.

[0383] In some embodiments, Fig.18A and Fig.18B As shown, at least part of the low-pressure charging and suction accessories overlap at least partly with the battery pack 13 in the up and down direction, so that the low-pressure charging and suction accessories are arranged closely to the battery pack, and the arrangement is more compact.

[0384] In some embodiments, Fig.18A and Fig.18B As shown, the low-pressure charging and suction hose 122 and the battery pack 13 are both arranged at the rear of the portable charging and suction pump 100, and at least part of the low-pressure charging and suction hose 122 and the battery pack 13 overlap at least partly in the up and down direction.

[0385] In some embodiments, in order to avoid the low-pressure inflator accessories being exposed and easily lost or causing the appearance of the whole machine to be unsightly, such as Fig.15As shown, a cover 18 is connected to the low-pressure accessory housing 140A, and the low-pressure accessory housing 140A and the cover 18 can be pivotally connected or connected by a buckle structure, which is not limited here. In this embodiment, the low-pressure accessory housing 140A and the cover 18 can be pivotally connected. If the user needs to take the low-pressure inflatable and inhalable accessories, the cover 18 is pivotally opened to take them. After use, the low-pressure inflatable accessories are stored in the low-pressure accessory storage portion 14A, and the cover 18 is closed.

[0386] Optionally, the cover 18 is made of a transparent or translucent material, and the user can check the status of the low-pressure charging and suction accessories in the low-pressure accessory storage portion 14A when the cover 18 is closed.

[0387] Alternatively, if Figure 1 , Figure 8 and Fig.15 As shown, a low-pressure air inlet opening 180 is provided on the cover 18 at a position corresponding to the through-opening 146A, and the air inlet pipe 1210 passes through the through-opening 146A and extends to the low-pressure air inlet opening 180 .

[0388] Optional, such as Figure 1 and Figure 8 As shown, when the cover 18 is in the closed state, the end of the air inlet pipe 1210 is flush with the upper surface of the cover 18.

[0389] In some embodiments, Figure 1 and Fig.15 As shown, a handle 15 is also pivotally mounted on the low-voltage accessory housing 140A. In other embodiments, the handle 15 can also be pivotally mounted on the main housing 106.

[0390] In some embodiments, Figure 1 As shown, the portable charging and suction pump 100 further includes a lighting module (not shown). The lighting module includes a light-emitting member 1043 connected to the battery pack 13, and the second side wall 102 of the main body housing 106 has a mounting opening adapted to the shape of the light-emitting member 1043. The light-emitting member 1043 is mounted on the mounting opening to emit light, thereby realizing the lighting function of the portable charging and suction pump and increasing the practical function of the portable charging and suction pump.

[0391] In some embodiments, Figure 1 and Figure 1AAs shown, the portable charging and suction pump 100 also includes a user operation interface 1010, which is arranged on the first side wall 101. The user operation interface 1010 includes a display screen 1010A, a control button 1010B and a knob 1010C for adjusting the pressure value, which are connected to the control mainboard signal. The control mainboard is signal-connected to the charging and suction component and the lighting module (not shown), so that the control button 1010B can be used to control the opening and closing of the charging and suction component and the lighting module, and the pressure value can be adjusted by the knob 1010C. The current status information of the charging and suction component and the lighting module can be displayed in real time through the display screen 1010A, thereby realizing automatic control of the portable charging and suction pump.

[0392] In the present application, the portable charging and suction pump 100 includes at least three modules: a high-voltage module, a charging and suction component, and a battery pack. In order to diversify the functions of the portable charging and suction pump 100, a low-voltage module will also be included. First, by designing the layout between the high-voltage module and the low-voltage module, space is saved in the length direction, width direction, and height direction respectively; secondly, by further arranging the battery pack, space is further saved in the length direction, width direction, and height direction, so as to achieve the purpose of compact structure and miniaturization of the portable charging and suction pump; finally, the remaining space inside the portable charging and suction pump is fully utilized to layout the charging and suction components, saving the space occupied by the accessories when they are stored. In this way, the compactness between the modules installed on the outer shell of the portable charging and suction pump is maximized, so that the portable charging and suction pump can achieve the purpose of miniaturization.

[0393] like Figure 1 and Fig.19 As shown, the miniaturization of the portable charging and suction pump in the present application can achieve the following parameters: the length L ranges from 150mm to 200mm, and the length L is the maximum straight-line distance of the portable charging and suction pump in the left-right direction. In the present embodiment, the length L is specifically the straight-line distance between the third side wall of the outer shell 10 and the high-pressure air outlet opening end or the low-pressure air outlet opening end in the left-right direction; the width W ranges from 120mm to 140mm, and the width W is the maximum straight-line distance of the portable charging and suction pump in the front-to-back direction. In the present embodiment, the width W is specifically the longest straight-line distance between the first side wall and the second side wall of the outer shell 10 in the front-to-back direction; the height H ranges from 175mm to 195mm, and the height H is the maximum straight-line distance of the portable charging and suction pump in the up-down direction. In the present embodiment, the height H is specifically the straight-line distance between the upper surface of the cover 18 and the supporting surface located below that supports the portable charging and suction pump in the up-down direction. In order to ensure that the portable charging and suction pump has a compact structure, the present invention improves space utilization by rationally arranging the various components of the whole machine, thereby miniaturizing the volume of the portable charging and suction pump without sacrificing function and performance, so that the portable charging and suction pump is in a relatively reasonable size.

[0394] In order to diversify the functions of the portable charging and suction pump and apply it to different scenarios, the portable charging and suction pump includes a high-pressure module and a low-pressure module. Through reasonable layout, the size of the charging and suction assembly formed by the combination of the high-pressure module and the low-pressure module is miniaturized, and the following parameters can be achieved: Fig. 20A and Fig. 20B As shown, the range of the length L1 of the charging and suction assembly is: 110mm~135mm, and the length L1 is the straight-line distance between the cooling fan 1101 and the end of the air outlet pipe 1211 in the left-right direction; the range of the width W1 is 75mm~95mm, and the width W1 is the straight-line distance between the front end of the driven wheel 1122 and the rear end of the fan housing 121 in the front-to-back direction; the range of the height H1 is 154mm~174mm, and the height H1 is the straight-line distance between the end of the air inlet pipe 1210 and the lower end of the driven wheel 1122 in the up-down direction.

[0395] The length ratio L:L1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1.1:1 to 1.8:1; the width ratio W:W1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1.3:1 to 1.9:1; the height ratio H:H1 of the portable charging and suction pump and the charging and suction assembly is in the range of 1:1 to 1.3:1. In summary, the present application optimizes the layout of the components of the portable charging and suction pump, so that the portable charging and suction pump has a compact structure.

[0396] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
