[0040] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0041] Please see Figure 1 and Figure 2The air pump 100 of this application embodiment includes a housing assembly 10 and a first air passage assembly 20, a second air passage assembly 30, a connecting pipe 40, an air nozzle assembly 50, a drive assembly 60, and a pressure detection assembly 70 disposed inside the housing assembly 10, as well as a connector 80 disposed outside the housing. The air pump 100 of this application embodiment has at least the following three beneficial effects: Firstly, the first air passage assembly 20 and the second air passage assembly 30 are respectively connected to the connecting pipe 40, the air nozzle assembly 50 is connected to the connecting pipe 40, and the drive assembly 60 is connected to the first air passage assembly 20 and the second air passage assembly 30. The drive assembly 60 has inflation and deflation functions, so that the first air passage assembly 20 and the second air passage assembly 30 share a single air nozzle assembly 50 to inflate and deflate external objects, simplifying the structure of the air pump 100 and improving ease of use. Secondly, the pressure detection component 70 is disposed on the connecting pipe 40. The pressure detection component 70 is used to detect the airflow pressure inside the connecting pipe 40, thereby detecting the air pressure during the inflation and deflation processes to accurately control the inflation and deflation volume of external objects. Thirdly, the connector 80 is detachably connected to the outside of the housing assembly 10. When the connector 80 is needed, it is detached from the housing assembly 10 and connected to the air nozzle assembly 50. When the connector 80 is not needed, it can be stored on the housing assembly 10 to prevent loss. The air pump of this embodiment has a compact structure, high integration, and simplified structure to reduce volume, effectively improving the ease of use of the air pump 100.

[0042] In some embodiments, the external object may be a gas-filled sphere, tire, balloon, or other object that needs to be filled with gas, which are not listed one by one in the embodiments of this application. The air pump 100 of this application can be used to inflate objects with insufficient air pressure, to depressurize objects with excessive air pressure, or to depressurize objects when they need to be stored to facilitate storage.

[0043] For the housing assembly 10 described above, please refer to... Figures 2 to 4 The housing assembly 10 has a first end 10a and a second end 10b at its two ends, respectively. A receiving space 121 is formed between the first end 10a and the second end 10b. The aforementioned first air passage assembly 20, second air passage assembly 30, connecting pipe 40, air nozzle assembly 50, drive assembly 60, and pressure detection assembly 70 are disposed within the receiving space 121 to secure and protect these components. Please refer to [link / reference]. Figure 5 The first end 10a of the housing assembly 10 is also provided with a storage groove 1313, the opening of which communicates with the outside. The connector 80 is detachably disposed in the storage groove 1313 to facilitate the user to take out and insert the connector 80.

[0044] In some embodiments, the receiving slot 1313 may be connected to the receiving space 121, so that the drive component 60 located in the receiving space 121 can exchange airflow with the outside through the receiving slot 1313, and the various components located in the receiving space 121 can exchange heat with the outside through the receiving slot 1313 for timely heat dissipation. In other embodiments, the receiving slot 1313 may not be connected to the receiving space 121, that is, the receiving slot 1313 is an independent space, and the receiving space 121 is connected to the outside through other structures.

[0045] In some embodiments, please refer to Figure 5 and Figure 6 The first end 10a of the housing assembly 10 is provided with a first notch 11, which connects the receiving space 121 to the outside. The air nozzle assembly 50 is fixedly connected to the housing assembly 10 and communicates with the first notch 11 so that the connector 80 can be connected to the air nozzle assembly 50 to inflate or deflate external objects. In this embodiment, the air pump 100 is provided with both a receiving groove 1313 and a first notch 11 at the first end 10a of the housing assembly 10, so that the connector 80 and the air nozzle assembly 50 are located on the same side of the housing assembly 10. This allows the user to quickly retrieve the connector 80 and quickly install it with the air nozzle assembly 50. On the other hand, it makes full use of the space at the first end 10a of the housing assembly 10, avoiding the need to set up the receiving groove 1313 in other areas of the housing assembly 10, thus saving the receiving space 121.

[0046] Further, please refer to Figure 7 The first end 10a of the housing assembly 10 has a cylindrical structure, and the first notch 11 is circular and coaxially arranged with the first end 10a. A receiving groove 1313 is located around the first notch 11. This structure allows the first notch 11 to be located in the central region of the first end 10a, thus enabling the nozzle assembly 50 to be positioned in the central region of the first end 10a, allowing for the reasonable assembly of a nozzle assembly 50 with a certain volume. After the nozzle assembly 50 is installed, there is still sufficient space around the first end 10a to accommodate the receiving groove 1313. The positions of the connector 80 and the nozzle assembly 50 do not interfere with each other, resulting in a reasonable layout and a compact overall structure for the first end 10a.

[0047] Of course, in other embodiments, the first end 10a of the housing assembly 10 can be constructed into other shapes, such as square, triangular, elliptical, etc., according to actual production needs. In addition, the center of the first notch 11 can be coaxial with the geometric center of the first end 10a, or non-coaxial, to adapt to the layout of other structures or the assembly of components.

[0048] In some embodiments, please refer to Figure 8 The housing assembly 10 includes a housing component 12 and an end cap component 13. The end cap component 13 is connected to one end of the housing component 12 to form the first end portion 10a described above. The housing component 12 has a receiving space 121, and the end cap component 13 has a receiving groove 1313. Further, the housing component 12 has a first hole 1221, and the end cap component 13 has a second hole 13111. The first hole 1221 and the second hole 13111 communicate with each other and together form a first notch 11.

[0049] For the housing component 12 described above, please refer to... Figures 8 to 10 The housing component 12 includes a head 122 and a grip 123. Both the head 122 and the grip 123 are generally cylindrical, and the central axis K1 of the head 122 and the central axis K2 of the grip 123 are set at an angle, so that the overall structure of the housing component 12 is gun-shaped. This structure conforms to ergonomic design and is easy for users to hold.

[0050] In further embodiments, please refer to the following: Figure 4 The housing component 12 includes a first housing 124 and a second housing 125. The first housing 124 and the second housing 125 are connected together to form a head 122 and a gripping part 123, and together they enclose a receiving space 121. By setting the housing into two halves that fit together, it is easier to assemble the internal structure of the receiving space 121, reducing assembly difficulty, and also reducing the manufacturing difficulty of the housing component 12.

[0051] In some embodiments, please refer to Figure 4 Along the axial direction of the housing assembly 10, the receiving space 121 includes a first cavity 1211 and a second cavity 1212 that are axially distributed and connected. The first air passage assembly 20, the second air passage assembly 30, the connecting pipe 40, the air nozzle assembly 50, and the pressure detection assembly 70 are assembled to form a first integral S1. The first integral S1 is installed in the first cavity 1211, and the drive assembly 60 is installed in the second cavity 1212. This allows the first integral S1 and the drive assembly 60 to be axially distributed, reducing the radial volume and facilitating user grip. It is worth noting that in other embodiments, when the housing assembly 10 is constructed in other shapes such as L-shaped, straight, or wave-shaped, the receiving space 121 inside the housing assembly 10 can still include the first cavity 1211 and the second cavity 1212, or may also include multiple cavities such as a third cavity and a fourth cavity. These multiple cavities are not necessarily distributed axially.

[0052] In some embodiments, the head 122 has a through first hole 1221 and a first connecting region 1222 located on the outer surface of the head 122, and the outer surface of the grip portion 123 has a second connecting region 1231. The end cap component 13 can be sleeved on the first connecting region 1222 to simultaneously clamp the head 122 of the first housing 124 and the second housing 125, preventing the first housing 124 and the second housing 125 from separating, thereby enhancing the structural strength of the housing component 12. In some embodiments, the housing component 12 further includes a handle shell 126, which is sleeved on the second connecting region 1231 to simultaneously clamp the grip portion 123 of the first housing 124 and the second housing 125, preventing the first housing 124 and the second housing 125 from separating, thereby further enhancing the structural strength of the housing component 12.

[0053] In some embodiments, the grip portion 123 is provided with a first vent 1232 that connects the receiving space 121 to the outside, and the handle shell 126 is provided with a through second vent 1261. The first vent 1232 and the second vent 1261 are connected so that the receiving space 121 can exchange airflow and heat with the outside.

[0054] For the end cap component 13 described above, please refer to... Figures 8 to 11 The end cap component 13 includes a storage bracket 131, which is fitted onto the first connection area 1222 of the head 122. As an example, the storage bracket 131 includes a bottom wall 1311 and an annular side wall 1312 connected to the bottom wall 1311. The annular side wall 1312 extends axially, and a through second hole 13111 is formed in the central region of the bottom wall 1311. When the storage bracket 131 is connected to the first end 10a of the housing component 12, the annular side wall 1312 is tightly fitted onto the first connection area 1222 to fix the first housing 124 and the second housing 125. The first hole 1221 communicates with the second hole 13111 to expose the nozzle assembly 50, so that the connector 80 can be connected to the nozzle assembly 50.

[0055] In some embodiments, the receiving groove 1313 is formed on the receiving bracket 131, and the connector 80 is directly received in the receiving groove 1313, with a portion of the connector 80 abutting or not abutting against the inner wall of the receiving groove 1313. In other embodiments, the receiving groove 1313 may also be formed on the first end portion 10a of the housing member 12. As an example, a portion of the first end portion 10a of the housing member 12 is recessed to form the receiving groove 1313.

[0056] In some embodiments, the storage bracket 131 further includes a fixing portion 1314. When the connector 80 is installed in the storage groove 1313, the fixing portion 1314 is partially connected to the connector 80 to retain the connector 80 within the storage groove 1313 and prevent the connector 80 from coming out of the storage groove 1313. As an example, a hollow column 1315 extends from the bottom wall 1311 toward the housing component 12. The interior of the hollow column 1315 forms the aforementioned storage groove 1313, and the extended end of the hollow column 1315 gradually tapers to form the fixing portion 1314. The connector 80 includes a ball needle 81, which includes a connected base 811 and a needle portion 812. When the ball needle 81 is stored in the storage groove 1313, the needle portion 812 abuts against the fixing portion 1314 to fix the ball needle 81 as a whole. It is understandable that the hollow column 1315 can be integrally formed with the bottom wall 1311, or the hollow column 1315 and the bottom wall 1311, which are independent of each other, can be spliced ​​together to form a whole.

[0057] In other embodiments, such as Figure 11 As shown, when the diameter of the second hole 13111 on the bottom wall 1311 of the storage bracket 131 is large, the hollow column 1315 can be connected to or integrally formed on the annular side wall 1312, and the slot of the storage groove 1313 is directly connected to the second hole 13111 to expose the storage groove 1313.

[0058] In some embodiments, please refer to Figure 11 and Figure 12 The extended end of the hollow column 1315 may also include a first spring piece 13141 and a second spring piece 13142, which constitute the aforementioned fixing part 1314. The connector 80 located in the receiving groove 1313 abuts against the first spring piece 13141 and the second spring piece 13142 respectively. Specifically, both the first spring piece 13141 and the second spring piece 13142 are connected to the hollow column 1315, and the first spring piece 13141 and the second spring piece 13142 are spaced apart to form a gap 13143. At least one of the first spring piece 13141 and the second spring piece 13142 is elastic, thereby adjusting the size (dimension) of the gap 13143. When the needle part 812 of the ball needle 81 passes through the gap 13143, the needle part 812 presses the first spring piece 13141 and the second spring piece 13142, so that the needle part 812 abuts against the first spring piece 13141 and the second spring piece 13142. Under the clamping action of the first spring piece 13141 and the second spring piece 13142, the ball needle 81 is held in the storage groove 1313. When the user applies force to pull out the ball needle 81, the needle part 812 exits from the gap 13143 and separates from the first spring piece 13141 and the second spring piece 13142.

[0059] In some embodiments, please refer to Figure 11 and Figure 12 The storage bracket 131 also has a first limiting part 1316, which abuts against the connector 80 to limit the movement of the connector 80 within the storage groove 1313. As an example, the first limiting part 1316 and the fixing part 1314 are respectively disposed at both ends of the hollow column 1315, and the first limiting part 1316 defines at least a partial boundary of the opening of the storage groove 1313. When the ball needle 81 is inserted into the storage groove 1313, the needle portion 812 passes between the first spring piece 13141 and the second spring piece 13142, and the base portion 811 abuts against the first limiting part 1316 to limit further movement of the base portion 811 into the storage groove 1313, thereby reducing the difficulty of removing the ball needle 81.

[0060] In some embodiments, such as Figure 6 As shown, the base 811 has external threads, and the nozzle assembly 50 has internal threads. The ball needle 81 and the nozzle assembly 50 are connected by a screw thread. This allows for a quick and secure connection between the ball needle 81 and the nozzle assembly 50. Furthermore, when the ball needle 81 is stored in the storage groove 1313, the external threads of the base 811 are partially exposed at the opening of the storage groove 1313. The external threads help increase the friction when the user removes the ball needle 81, making it easier to remove it from the storage groove 1313. It is understood that the connector 80 and the nozzle assembly 50 can also be connected by other methods such as snap-fit ​​or locking.

[0061] In some embodiments, please refer to Figure 13 The connector 80 may further include an extension tube 82, which extends the distance between the ball needle 81 and the nozzle assembly 50 to accommodate more usage scenarios. As an example, one end of the extension tube 82 is detachably connected to the nozzle assembly 50, and the other end is detachably connected to the ball needle 81. Furthermore, the extension tube 82 is a flexible tube, allowing the ball needle 81 to swing at any position relative to the nozzle assembly 50, increasing the flexibility of the ball needle 81.

[0062] In some embodiments, please refer to Figure 5 and Figure 6 The end cap component 13 also includes a protective plug 132, which is disposed on the storage bracket 131 and is used to open or close the opening of the storage slot 1313. As an example, please refer to... Figure 8 and Figure 12The protective plug 132 includes a traction part 1321 and a sealing part 1322 connected together. The traction part 1321 is fixedly connected to the storage bracket 131, and the sealing part 1322 is movable relative to the storage bracket 131 to open or close the opening of the storage slot 1313. This prevents debris from entering the storage slot 1313 and also covers the connector 80 located in the storage slot 1313, improving the overall aesthetics of the air pump 100. Furthermore, the protective plug 132 is made of rubber, which has good toughness and flexibility, thus extending its service life.

[0063] In some embodiments, please refer to Figure 7 and Figure 8 The end cap component 13 also includes a lighting lamp 133, which is disposed on the side of the storage bracket 131 opposite to the housing component 12. The lighting component is electrically connected to the internal structure of the air pump 100 to provide illumination during inflation or deflation, facilitating operation. Furthermore, the lighting lamp 133 has an arc-shaped structure to avoid the first notch 11 at the first end 10a. Even further, the lighting lamp 133 has a non-end-to-end arc-shaped structure to avoid the structure of the storage slot 1313. By setting the arc-shaped lighting lamp 133 structure, the illumination can be more uniform, facilitating the connection of the connector 80 to external objects.

[0064] For the first air path assembly 20, the second air path assembly 30, the connecting pipe 40, the air nozzle assembly 50, and the drive assembly 60 mentioned above, please refer to [link / reference]. Figure 14 and Figure 16 The connecting pipe 40 has three interconnected interfaces: a first interface 41, a second interface 42, and a third interface 43. The first interface 41 connects to the first air passage assembly 20, the second interface 42 connects to the second air passage assembly 30, and the third interface 43 connects to the nozzle assembly 50. The drive assembly 60 is connected to the first air passage assembly 20 and / or the second air passage assembly 30. The drive assembly 60 has an inflation function, or simultaneously has both inflation and deflation functions. This allows the first air passage assembly 20 and the second air passage assembly 30 to share a single nozzle assembly 50 to connect to external objects, thereby achieving inflation or deflation. This avoids switching between two separate inflation and deflation nozzles, effectively improving the user experience.

[0065] In an embodiment where the drive assembly 60 only has an inflation function, the drive assembly 60 only has an inflation end 631. The inflation end 631 is connected to one of the first air passage assembly 20 and the second air passage assembly 30, while the other is connected to the atmosphere. When an external object needs to vent, the inflation end 631 blows out gas, which enters the interior of the external object through the first air passage assembly 20 or the second air passage assembly 30. When an external object needs to vent, the gas inside the external object can flow directly to the outside through the first air passage assembly 20 or the second air passage assembly 30.

[0066] In an embodiment where the drive assembly 60 has both inflation and deflation functions, the drive assembly 60 includes an inflation end 631 and a deflation end 632. The inflation end 631 is connected to one of the first air passage assembly 20 and the second air passage assembly 30, while the deflation end 632 is connected to the other of the first air passage assembly 20 and the second air passage assembly 30.

[0067] As an example, the inflation end 631 is connected to the first air passage assembly 20, and the suction end 632 is connected to the second air passage assembly 30. When the connector 80 is connected to the nozzle assembly 50 and plugged into an external object, if the air pump 100 is set to inflation mode, the gas blown out by the inflation end 631 passes through the first air passage assembly 20, the connecting pipe 40, and the nozzle assembly 50, and then enters the external object through the connector 80 to inflate the object. If the air pump 100 is set to exhaust mode, the suction end 632 forms a negative pressure, and the gas inside the object flows to the suction end 632 after passing through the connector 80, the nozzle assembly 50, the connecting pipe 40, and the second air passage assembly 30, thereby exhausting the object.

[0068] As another example, the inflation end 631 is connected to the second air passage assembly 30, and the suction end 632 is connected to the first air passage assembly 20. When the connector 80 is connected to the nozzle assembly 50 and plugged into an external object, if the air pump 100 is set to inflation mode, the gas blown out by the inflation end 631 passes through the second air passage assembly 30, the connecting pipe 40 and the nozzle assembly 50, and then enters the external object through the connector 80 to inflate the object. If the air pump 100 is set to exhaust mode, the suction end 632 forms a negative pressure, and the gas inside the object flows to the suction end 632 after passing through the connector 80, the nozzle assembly 50, the connecting pipe 40 and the first air passage assembly 20, thereby exhausting the object.

[0069] Of course, in some embodiments, during the process of venting external objects, the suction end 632 of the drive component 60 may not be activated. Instead, the first air passage component 20 or the second air passage component 30 may be directly connected to the outside. Under the high pressure inside the object, the gas may be directly discharged to the outside to achieve the venting of the object.

[0070] In some embodiments, please refer to the following: Figure 15 The first air circuit assembly 20 includes a first switch 21, which has a first state and a second state. The second air circuit assembly 30 includes a second switch 31, which has a third state and a fourth state. The first switch 21 is connected to one of the charging end 631 and the suction end 632 of the drive assembly 60, and the second switch 31 is connected to the other of the charging end 631 and the suction end 632 of the drive assembly 60. By controlling the switching of the states of the first switch 21 and the second switch 31, the air pump 100 can switch between charging mode and exhaust mode.

[0071] As an example, both the first switch 21 and the second switch 31 are two-way valves. That is, the first state of the first switch 21 is the open state, the second state of the first switch 21 is the closed state, the third state of the second switch 31 is the closed state, and the fourth state of the second switch 31 is the open state.

[0072] Specifically, when the first switch 21 is in the first state, the first air circuit assembly 20 is in the open state, and the second switch 31 is in the third state, the second air circuit assembly 30 is in the closed state. At this time, the air pump 100 is in either the charging mode or the discharging mode. When the first switch 21 is in the second state, the first air circuit assembly 20 is in the closed state, and the second switch 31 is in the fourth state, the second air circuit assembly 30 is in the open state. At this time, the air pump 100 is in either the discharging mode or the charging mode.

[0073] As another example, please refer to Figure 16 and Figure 17 Both the first switch 21 and the second switch 31 are three-way valves. The first and second states of the first switch 21 are both in a closed state, but the gas movement paths are different. Similarly, the third and fourth states of the second switch 31 are also in a closed state, and the gas movement paths are also different. The air pump 100 switches between charging and discharging modes by changing the gas movement path within the first switch 21 and the second switch 31.

[0074] Specifically, the first switch 21 includes a first valve body 211 and a first valve core 212. The first valve body 211 has a first port 2111, a second port 2112, and a third port 2113, all of which connect the interior of the first valve body 211 to the outside. The first valve core 212 is movably disposed inside the first valve body 211. When the first valve core 212 blocks the third port 2113, the first port 2111 and the second port 2112 are connected, and the first switch 21 is in a first state. When the first valve core 212 blocks the second port 2112, the first port 2111 and the third port 2113 are connected, and the first switch 21 is in a second state.

[0075] The second switch 31 includes a second valve body 311 and a second valve core 312. The second valve body 311 has a fourth port 3111, a fifth port 3112, and a sixth port 3113, all of which connect the interior of the second valve body 311 to the outside. The second valve core 312 is movably disposed inside the second valve body 311. When the second valve core 312 blocks the sixth port 3113, the fourth port 3111 and the fifth port 3112 are connected, and the second switch 31 is in the third state. When the second valve core 312 blocks the fifth port 3112, the fourth port 3111 and the sixth port 3113 are connected, and the second switch 31 is in the fourth state.

[0076] In some embodiments, the drive assembly 60 includes an independent inflation pump body 61 and an air extraction pump body 62, wherein the inflation pump body 61 is provided with an inflation end 631 and the air extraction pump body 62 is provided with an air extraction end 632. The inflation pump body 61 and the air extraction pump body 62 can work independently without interfering with each other, or they can work together in coordination.

[0077] In other embodiments, please refer to Figure 15 The drive component 60 is a composite pump body 63, which integrates an inflation end 631 and an exhaust end 632. When the composite pump body 63 is started, the inflation end 631 and the exhaust end 632 work simultaneously, and gas is drawn in from the exhaust end 632 and blown out through the inflation end 631.

[0078] The following description uses the composite pump body 63 as an example to illustrate gas flow.

[0079] In a first embodiment, the first port 2111 of the first switch 21 is connected to the inflation end 631, the second port 2112 is connected to the first interface 41 of the connecting pipe 40, the third port 2113 is connected to the receiving space 121, the fourth port 3111 of the second switch 31 is connected to the suction end 632, the fifth port 3112 is connected to the receiving space 121, the sixth port 3113 is connected to the second interface 42 of the connecting pipe 40, and the third interface 43 of the connecting pipe 40 is connected to the air nozzle assembly 50.

[0080] Please see Figure 16 The arrows in the diagram indicate the direction of gas flow. When the air pump 100 is in inflation mode, the first switch 21 is in the first state and the second switch 31 is in the third state. Gas in the containment space 121 or external gas enters the interior of the second valve body 311 from the fifth port 3112. Since the second valve core 312 blocks the sixth port 3113, the gas flows through the fourth port 3111 to the suction end 632, and then is blown out from the inflation end 631 and enters the interior of the first valve body 211 from the first port 2111. Since the first valve core 212 blocks the third port 2113, the gas enters the interior of the connecting pipe 40 from the second port 2112 and the first interface 41. Since the sixth port 3113 is blocked by the second valve core 312, the gas in the connecting pipe 40 flows through the third interface 43 to the nozzle assembly 50, thereby inflating the external object.

[0081] Of course, in some embodiments, the composite pump body 63 has the function of directly absorbing gas from the receiving space 121 or the outside and discharging it from the inflation end 631. In this case, the gas path is as follows: the gas flows directly out from the inflation end 631 and enters the interior of the first valve body 211 from the first port 2111. Since the first valve core 212 blocks the third port 2113, the gas enters the interior of the connecting pipe 40 from the second port 2112 and the first interface 41. Since the sixth port 3113 is blocked by the second valve core 312, the gas in the connecting pipe 40 flows to the air nozzle assembly 50 through the third interface 43, thereby inflating the external object.

[0082] Please see Figure 17 The arrows in the diagram indicate the direction of gas flow. When the air pump 100 is in exhaust mode, the first switch 21 is in the second state and the second switch 31 is in the fourth state. Gas inside the external object enters the connecting pipe 40 from the nozzle assembly 50 through the third interface 43. Since the first valve core 212 blocks the second port 2112, the gas enters the second valve body 311 from the second interface 42 and the sixth port 3113. Since the second valve core 312 blocks the fifth port 3112, the gas flows from the fourth port 3111 to the suction end 632, and then is blown out from the inflation end 631 through the first port 2111 into the first valve body 211. Since the first valve core 212 blocks the second port 2112, the gas is discharged from the third port 2113 to the receiving space 121, and then discharged to the outside, or the gas is directly discharged to the outside from the third port 2113.

[0083] In the second embodiment, the other connection structures are the same as those in the first embodiment, except that: in the first embodiment, the first switch 21 is connected to the inflation end 631, and the second switch 31 is connected to the deflation end 632. Figure 16 It shows the airflow direction of its inflation mode. Figure 17 The airflow direction of its exhaust mode is shown. In the second embodiment, the first switch 21 is connected to the suction end 632, and the second switch 31 is connected to the inflation end 631. When the first switch 21 is in the second state and the second switch 31 is in the fourth state, the composite pump body 63 is in the inflation mode. When the first switch 21 is in the first state and the second switch 31 is in the third state, the composite pump body 63 is in the exhaust mode. Figure 18 The direction of the middle arrow indicates the airflow direction of its inflation mode. Figure 19 The direction of the middle arrow indicates the airflow direction of its exhaust mode.

[0084] Specifically, such as Figure 18As indicated by the middle arrow, the air pump 100 is in inflation mode. Gas from the outside or the containment space 121 enters the first valve body 211 from the third port 2113. Since the first valve core 212 blocks the second port 2112, the gas flows from the first port 2111 to the suction end 632 and flows out from the inflation end 631. It then enters the second valve body 311 through the fourth port 3111. Since the second valve core 312 blocks the fifth port 3112, the gas enters the connecting pipe 40 from the sixth port 3113 and the second interface 42. Since the first valve core 212 blocks the second port 2112, the gas in the connecting pipe 40 flows to the air nozzle assembly 50 and enters the outside object through the connector 80, thus achieving inflation.

[0085] Of course, when the composite pump body 63 has the function of directly drawing gas from the outside or the containment space, the airflow from the inflation end 631 enters the interior of the second valve body 311 from the fourth port 3111. Since the second valve core 312 blocks the fifth port 3112, the gas enters the connecting pipe 40 from the sixth port 3113 and the second interface 42. Since the first valve core 212 blocks the second port 2112, the gas in the connecting pipe 40 flows to the air nozzle assembly 50 and enters the external object through the connector 80 to achieve inflation.

[0086] like Figure 19 As indicated by the middle arrow, the air pump 100 is in exhaust mode. Gas inside the external object enters the connecting pipe 40 through the connector 80 and the air nozzle assembly 50. Since the second valve core 312 blocks the sixth port 3113, the gas enters the first valve body 211 from the first interface 41 and the second port 2112. Since the first valve core 212 blocks the third port 2113, the gas flows from the first port 2111 to the suction end 632. The gas in the composite pump body 63 enters the second valve body 311 from the inflation end 631 through the fourth port 3111. Since the second valve core 312 blocks the sixth port 3113, the gas is discharged from the fourth port 3111 to the fifth port 3112 into the receiving space 121 and then to the outside, or directly to the outside from the fifth port 3112.

[0087] In some embodiments, the first switch 21 and the second switch 31 may be switches of the same specification and installed in the same orientation. For details, please refer to... Figure 16 and Figure 17The first port 2111 and the second port 2112 of the first switch 21 are both located to the left of the third port 2113. The fourth port 3111 and the fifth port 3112 of the second switch 31 are both located to the left of the sixth port 3113. When the first switch 21 switches from the first state to the second state and the second switch 31 switches from the third state to the fourth state, the first valve core 212 and the second valve core 312 both move to the left. Conversely, when the first switch 21 switches from the second state to the first state and the second switch 31 switches from the fourth state to the third state, the first valve core 212 and the second valve core 312 both move to the right.

[0088] The advantages of the structure described in this application are as follows: Firstly, using switches of the same specification reduces the variety of parts in the air pump 100, lowers assembly difficulty, and helps reduce production costs. Secondly, since the first valve core 212 and the second valve core 312 move in the same direction, the program instructions for controlling the first switch 21 and the second switch 31 can be simplified. That is, the same instruction can be input to achieve state switching between the first switch 21 and the second switch 31, reducing control difficulty and energy consumption. Of course, in other embodiments, the first switch 21 and the second switch 31 can be of different specifications and installed in different postures.

[0089] In some embodiments, both the first switch 21 and the second switch 31 are solenoid valves, which can be controlled by program instructions to switch the first switch 21 between a first state and a second state, and the second switch 31 between a third state and a fourth state. Of course, in other embodiments, the first switch 21 and the second switch 31 can be other switching valves, such as mechanical valves, pneumatic valves, etc.

[0090] In some embodiments, please refer to Figure 20The first switch 21, the second switch 31, and the composite pump body 63 are distributed axially in the housing assembly 10. There is a certain distance between the first port 2111 of the first switch 21 and the inflation end 631, and between the fourth port 3111 of the second switch 31 and the suction end 632. Therefore, the first air passage assembly 20 includes a first pipe 22, which connects the first port 2111 and the inflation end 631. Further, the first pipe 22 is a flexible hose, which facilitates the connection between the first port 2111 and the inflation end 631 inside the housing assembly 10. The second air passage assembly 30 includes a second pipe 32, which connects the fourth port 3111 and the suction end 632. Further, the second pipe 32 is a flexible hose, which facilitates the connection between the fourth port 3111 and the suction end 632 inside the housing assembly 10. In some embodiments, the second air passage assembly 30 further includes a third pipe 33, which connects the sixth port 3113 and the second interface 42. Furthermore, the second conduit 32 is a flexible hose, which facilitates the connection of the sixth port 3113 and the second interface 42 inside the housing assembly 10.

[0091] In some embodiments, please refer to Figure 17 and Figure 20 The distance between the first port 2111 and the second port 2112 of the first switch 21 is relatively close, and the first port 2111 and the first pipe 22 form an angle of about 90 degrees. In order to avoid excessive local bending of the first pipe 22, the connecting pipe 40 is also provided with a fourth interface 45 and a fifth interface 46. The fourth interface 45 and the fifth interface 46 are connected and both are connected to the outside. However, a baffle 47 is provided between the fourth interface 45 and the first interface 41, so that the fourth interface 45 and the fifth interface 46 are not directly connected to the first interface 41, the second interface 42 and the third interface 43, so as to ensure that the gas flowing from the fifth interface 46 and the fourth interface 45 first passes through the first switch 21, and then flows into the connecting pipe 40 through the first interface 41.

[0092] When the first switch 21 is connected to the connecting pipe 40, the first port 2111 of the first switch 21 is connected to the fourth interface 45, the second port 2112 is connected to the first interface 41, and the first pipe 22 is connected to the fifth interface 46. This structure can reduce the local bending degree of the first pipe 22 and extend its service life; on the other hand, it allows the first switch 21 and the connecting pipe 40 to be directly connected, with the two supporting and fixing each other, enhancing the connection's firmness.

[0093] It is worth noting that, in order to further enhance the sealing of the connection, sealing elements can be installed at the connection points of the first port 2111, the second port 2112, the fourth port 3111, the sixth port 3113, etc., with the connecting pipe 40, the first pipe 22, the second pipe 32, and the third pipe 33, to prevent air leakage at the connection and enhance airtightness.

[0094] In some embodiments, please refer to Figure 17 and Figure 20 The nozzle assembly 50 includes a nozzle body 51 and a fourth pipe 52. The nozzle body 51 is disposed at the head 122 of the housing component 12, and the fourth pipe 52 connects the nozzle body 51 and the third interface 43 of the connecting pipe 40. Further, the fourth pipe 52 is a flexible hose. A first switch 21 and a second switch 31 are disposed at the grip portion 123 of the housing component 12. Since the grip portion 123 and the head 122 of the housing component 12 have a certain angle, connecting the nozzle body 51 and the third interface 43 via the flexible fourth pipe 52 reduces the difficulty of connection.

[0095] The gas inside balls such as basketballs, soccer balls, and volleyballs, as well as external objects like tires, typically has a rated pressure. Over- or under-pressure of the gas affects its performance. Therefore, during inflation or deflation, the gas pressure needs to be monitored to ensure it meets the rated pressure requirements.

[0096] Please see Figure 2 In this embodiment of the air pump 100, the first air path assembly 20 and the second air path assembly 30 share a single air nozzle assembly 50 during both the inflation and deflation processes via a connecting pipe 40, simplifying the component structure. Compared to a structure that uses two pressure detection components 70 to separately detect inflation and deflation pressures, this embodiment connects a single pressure detection component 70 to the connecting pipe 40, enabling simultaneous monitoring of pressure during both inflation and deflation processes, further simplifying the pressure monitoring components.

[0097] In some embodiments, please refer to Figure 14 and Figure 16 The connecting pipe 40 is equipped with a detection interface 44, which is connected to the first interface 41, the second interface 42, and the third interface 43. Specifically, the first air path assembly 20 is connected to the first interface 41, the second air path assembly 30 is connected to the second interface 42, the air nozzle assembly 50 is connected to the third interface 43, and the pressure detection assembly 70 is disposed at the detection interface 44. Furthermore, the detection interface 44 is positioned between the first interface 41 and the second interface 42, thus positioning the pressure detection assembly 70 between the first switch 21 and the second switch 31. This effectively utilizes the space within the receiving space 121, resulting in a rational layout and a more compact structure.

[0098] In some embodiments, please refer to Figure 14 and Figure 15 The air pump 100 also includes a first bracket 91, which is disposed within the receiving space 121. The first switch 21 and the second switch 31 are disposed on the same side of the first bracket 91, and the first switch 21 and the second switch 31 are spaced apart, such that the pressure detection component 70 is disposed between the first switch 21 and the second switch 31.

[0099] Furthermore, please refer to the following: Figure 20 The first bracket 91 is provided with a first receiving groove 911 and a second receiving groove 912. The first switch 21 is disposed in the first receiving groove 911, and the second switch 31 is disposed in the second receiving groove 912. This enhances the connection between the first switch 21 and the second switch 31 and the first bracket 91, and facilitates assembly. As examples, the first switch 21 and the second switch 31 can be fixed by means of screw connection, snap connection, fastening connection, interference fit connection, etc.

[0100] In some embodiments, please refer to Figure 2 and Figure 4 The air pump 100 also includes a control component 92, which is partially disposed within the housing space 121 and partially exposed to the outside world through a display window 1233, so that the control component 92 can interact with the user. As an example, please refer to... Figure 13 and Figure 14 The control component 92 includes a circuit board component 921, which is disposed on the side of the first bracket 91 opposite to the first switch 21 and the second switch 31. The circuit board component 921 is electrically connected to the first switch 21, the second switch 31, and the pressure sensor 71 to realize programmed command control and data transmission of the aforementioned components. By placing the circuit board component 921 on the other side of the first bracket 91, the installation position of the first bracket 91 can be utilized more efficiently, reducing installation difficulty, and also avoiding interference between the installation of the circuit board component 921 and the first switch 21 and the second switch 31.

[0101] In some embodiments, please refer to Figure 15 and Figure 16The pressure detection assembly 70 includes a pressure sensor 71 and a first seal 72. The pressure sensor 71 is directly soldered to the surface of the circuit board component 921. At this time, there is a certain distance between the pressure sensor 71 and the detection interface 44. The first bracket 91 is provided with a first extension wall 913. At least a portion of the first extension wall 913 extends toward the connecting pipe 40. The first extension wall 913 encloses a detection channel 9131, which is connected to the detection interface 44. At least a portion of the pressure sensor 71 is located inside the detection channel 9131. The first extension wall 913 is sealed to the connecting pipe 40 through the first seal 72 to prevent air leakage at the connection between the detection channel 9131 and the detection interface 44, thereby improving airtightness.

[0102] In this embodiment, a first extension wall 913 is provided on the first bracket 91, and the first extension wall 913 is directly connected to the connecting pipe 40, which connects the detection interface 44 and the detection channel 9131. Thus, the pressure sensor 71, directly soldered onto the surface of the circuit board component 921, can detect the air pressure during the inflation and deflation processes. In some embodiments, the first extension wall 913 on the first bracket 91 extends towards the circuit board component 921, such that the end of the first extension wall 913 abuts against the circuit board component 921 to cover the pressure sensor 71. In other embodiments, the first extension wall 913 may also be formed by the side wall of the connecting pipe 40 surrounding the detection interface 44 extending directly towards the circuit board component 921, with the first sealing member 72 disposed between the first extension wall 913 and the circuit board component 921.

[0103] In some embodiments, please refer to Figure 15 and Figure 16 The first bracket 91 is provided with a through clearance opening 914, which is connected to the detection channel 9131. The pressure sensor 71 is located at the clearance opening 914. The pressure detection assembly 70 also includes a second seal 73, which is arranged around the clearance opening 914 to seal the gap 13143 between the circuit board component 921 and the first bracket 91, preventing air leakage at the connection between the circuit board component 921 and the first bracket 91.

[0104] In other embodiments, the first support 91 does not have a first extension wall 913, nor is the first extension wall 913 provided on the detection interface 44 of the connecting pipe 40. The pressure sensor 71 is electrically connected to the circuit board component 921 via a conductive wire. The conductive wire passes through the detection interface 44, so that the pressure sensor 71 is located inside the connecting pipe 40. A sealing element is provided at the detection interface 44 to seal the gap between the conductive wire and the detection interface 44. Through the above arrangement, the manufacturing difficulty of the first support 91 and the connecting pipe 40 can be reduced.

[0105] However, compared to the embodiment where the pressure sensor 71 is not directly mounted on the circuit board component 921, directly soldering the pressure sensor 71 onto the circuit board component 921 can be easily achieved through methods such as surface mount heating soldering, which is less difficult to process. Furthermore, the circuit board component 921 is located on the side of the first bracket 91 away from the connecting pipe 40, and the connecting pipe 40 is fixedly connected to the first bracket 91 via the first extension wall 913. Therefore, when the pressure sensor 71 needs maintenance, the circuit board component 921 can be removed from the first bracket 91 to expose the pressure sensor 71, enabling quick disassembly, maintenance, and replacement of the pressure sensor 71. At this time, the connecting pipe 40, the first switch 21, and the second switch 31 remain connected to the first bracket 91 as a whole. The entire maintenance process is simple to disassemble and facilitates quick reassembly, improving maintenance efficiency.

[0106] In some embodiments, please refer to Figure 14 and Figure 15 The control component 92 also includes an operation component 922, which is located on the side of the circuit board component 921 opposite to the first bracket 91. The operation component 922 is electrically connected to the circuit board component 921 and is used to display information and interact with the user. Please refer to the following: Figure 4 The housing assembly 10 is provided with a through display window 1233, which connects the first cavity 1211 of the receiving space 121 to the outside. The operating component 922 is connected to the housing assembly 10 and is located at the display window 1233.

[0107] Furthermore, the operating component 922 includes a display screen 9221 and buttons 9222. The display screen 9221 is used to display information, and the buttons 9222 are used by the user to press to input commands. Of course, in other embodiments, the operating component 922 includes a touch-sensitive display screen 9221, which integrates virtual buttons 9222, and the touch-sensitive display screen 9221 can simultaneously realize information display and user interaction.

[0108] In some embodiments, please refer to Figure 20 and Figure 21The air pump 100 also includes a power supply assembly 93, which is disposed within the receiving space 121 and electrically connected to the circuit board component 921 of the control assembly 92. Specifically, the power supply assembly 93, the first switch 21, and the second switch 31 are located on the same side of the first bracket 91. The first switch 21 and the second switch 31 are arranged along the axial direction of the power supply assembly 93 and are arranged side by side on the side of the power supply assembly 93. Further, the first bracket 91 is provided with a battery compartment 915, and a first receiving slot 911 and a second receiving slot 912 are arranged adjacent to the battery compartment 915. With this arrangement, the bulky circuit board component 921 can be located above the battery assembly and the first switch 21 and the second switch 31, effectively utilizing space and resulting in a compact structure.

[0109] With the above structure, the first air passage assembly 20, the second air passage assembly 30, the connecting pipe 40, the pressure detection assembly 70, the control assembly 92, and the power supply assembly 93 are assembled on the first bracket 91 to form the first integral S1.
