Description

Technical Field

[0001] This utility model relates to the technical field of air pumps, and in particular to a dual-power air pump. Background Technology

[0002] With the widespread use of portable air pumps in outdoor equipment refilling and other scenarios, users' demands for power compatibility are becoming increasingly diversified. Currently, most portable air pumps on the market use a single USB interface (such as the traditional USB Type-C) for power supply. While this design can meet the needs of drawing power from devices such as power banks and household chargers indoors, it has obvious limitations in complex usage scenarios.

[0003] In outdoor or in-vehicle environments, besides USB Type-C power, DC round-head interfaces (such as 12V vehicle power output interfaces) are common power sources. Due to their high-voltage characteristics, DC round-head interfaces allow air pumps to operate efficiently in high-power mode, making them particularly suitable for large inflatable products such as outdoor inflatable mattresses. However, existing air pumps that only support USB Type-C interfaces cannot be directly adapted to DC round-head interfaces, requiring additional voltage conversion cables or adapters. This not only increases the user's carrying burden and operating costs but may also lead to unstable power supply due to compatibility issues during conversion, affecting inflation efficiency and even device safety.

[0004] Therefore, in order to solve the problem of poor compatibility when using a single power interface, this application proposes a dual-power air pump that is compatible with both USB Type-C interface and DC round head interface. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-power air pump that can be simultaneously compatible with both USB Type-C interface and DC round head interface to solve the problem of poor applicability of a single power interface.

[0006] The objective of this utility model is achieved through the following technical solution: A dual-power air pump, characterized in that it comprises: Pump casing; Centrifugal fan, the centrifugal fan being mounted on the pump casing; and A circuit board is disposed inside the pump housing and is electrically connected to the centrifugal fan. The circuit board is provided with a USB Type-C socket and a DC round-head socket, and both the USB Type-C socket and the DC round-head socket pass through the pump housing and extend to the outer wall of the pump housing.

[0007] Optionally, the centrifugal fan includes a volute, a motor, and an impeller. The volute is disposed on the pump casing, the motor is disposed on the outer wall of the volute and is located inside the pump casing, and the impeller is disposed on the output shaft of the motor and is located inside the volute.

[0008] Optionally, a heat dissipation hole is provided on the end face of the pump housing away from the volute.

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0021] like Figures 1 to 3 As shown, a dual-power air pump 10 includes a pump housing 100, a centrifugal fan 200, and a circuit board 300. The centrifugal fan 200 is disposed on the pump housing 100, and the circuit board 300 is disposed inside the pump housing 100. The circuit board 300 is electrically connected to the centrifugal fan 200. The circuit board 300 is provided with a USB Type-C socket 310 and a DC round-head socket 320, and both the USB Type-C socket 310 and the DC round-head socket 320 pass through the pump housing 100 and extend to the outer wall of the pump housing 100.

[0022] It should be noted that the centrifugal fan 200 is mounted on the pump housing 100, and the circuit board 300 is mounted on the inner wall of the pump housing 100. The circuit board 300 has a USB Type-C socket 310 and a DC round-head socket 320 installed at intervals, both extending from one side wall of the pump housing 100. Thus, the dual-power air pump 10 of this application can be powered by plugging into the USB Type-C socket 310 via the Type-C interface, and charged via plugging into the DC round-head socket 320 via the DC round-head interface. It is compatible with both common 5V Type-C and 12V DC round-head interfaces, making the air pump more suitable for use with common power bank-powered devices or outdoor applications such as car cigarette lighter power outlets, effectively improving its applicability.

[0023] like Figures 1 to 3 As shown, in one embodiment, the centrifugal fan 200 includes a volute 210, a motor 220, and an impeller 230. The volute 210 is disposed on the pump casing 100, the motor 220 is disposed on the outer wall of the volute 210 and is located inside the pump casing 100, and the impeller 230 is disposed on the output shaft of the motor 220 and is located inside the volute 210.

[0024] It should be noted that the centrifugal fan 200 is configured with a volute fan structure, which can effectively increase the pumping pressure of the air pump. The pump housing 100 is fixed to the pump housing 100 with screws. The motor 220 is located inside the pump housing 100 for protection. In one embodiment, both the volute 210 and the pump housing 100 are made of plastic.

[0025] like Figure 2 and Figure 3 As shown, in one embodiment, a heat dissipation hole 110 is provided on the end face of the pump housing 100 away from the volute 210.

[0026] It should be noted that, in order to allow the heat generated by the motor 220 to be dissipated from the pump housing 100, heat dissipation holes 110 are provided on the bottom surface of the pump housing 100. This allows the heat from the motor 220 to be quickly dissipated through the heat dissipation holes 110.

[0027] like Figure 2 As shown, in one embodiment, the volute 210 is provided with a slot 211, and the opening edge of the pump housing 100 is accommodated in the slot 211.

[0028] It should be noted that, in order to ensure a tight fit between the volute 210 and the pump housing 100, a slot 211 is formed on one side of the volute 210. In one embodiment, two protrusions with shapes matching the opening edge of the pump housing 100 can be integrally formed on one side of the volute 210. The distance between the two protrusions together forms the slot 211, and the width of the slot 211 is adapted to the thickness of the opening edge of the pump housing 100. This allows the pump housing 100 to be snapped and fixed within the slot 211, ensuring a tight fit between the pump housing 100 and the volute 210. On the one hand, the slot 211 provides positioning during assembly of the pump housing 100 and the volute 210, improving assembly efficiency; on the other hand, it enhances the structural strength of the installation of the pump housing 100 and the volute 210.

[0029] like Figures 2 to 4 As shown, in one embodiment, a plurality of first fixing posts 120 are provided inside the pump housing 100, and a plurality of second fixing posts 240 are provided on the volute 210, with the first fixing posts 120 respectively connected to each of the second fixing posts 240.

[0030] It should be noted that, in order to reliably fix the pump housing 100 and the volute 210, a first fixing post 120 is provided on the pump housing 100, and a second fixing post 240 is provided on the volute 210. Thus, by passing a screw through the first fixing post 120 and then screwing it to the second fixing post 240, the volute 210 and the pump housing 100 can be fixedly installed.

[0031] like Figure 2 As shown, in one embodiment, a positioning groove 241 is provided on the second fixing post 240, and the first fixing post 120 is adapted to be accommodated in the positioning groove 241.

[0032] It should be noted that, in order to further improve the assembly efficiency of the pump casing 100 and the centrifugal fan 200, the first fixing column 120 is inserted into the positioning groove 241 for positioning, so that the pump casing 100 and the volute 210 can be quickly aligned and positioned, and then fixedly installed.

[0033] like Figures 1 to 3 As shown, in one embodiment, a start switch 330 is also provided on the circuit board 300, and the start switch 330 passes through the pump housing 100 to extend to the outer side wall of the pump housing 100.

[0034] It should be noted that the start switch 330 can be a common push-button switch, which is soldered onto the circuit board 300, and the pressing part extends through the pump housing 100 to the outside of the pump housing 100. In this way, the user can start or stop the air pump by pressing the start switch 330.

[0035] like Figures 1 to 3As shown, in one embodiment, the circuit board 300 is also provided with an indicator light 340, which passes through the pump housing 100 and extends to the outer wall of the pump housing 100.

[0036] It should be noted that, in order to provide feedback to the user on whether the air pump is currently powered normally, an indicator light 340 is also soldered and installed on the circuit board 300. When the air pump is powered normally, the indicator light 340 is lit, and when the power is off, the indicator light 340 is off.

[0037] like Figure 4 As shown, in one embodiment, a material embedding groove 130 is provided on the inner side wall of the pump housing 100, and the circuit board 300 is embedded in the material embedding groove 130.

[0038] It should be noted that, in order to improve the stability of the circuit board 300 within the pump housing 100 and to allow for quick installation of the circuit board 300 within the pump housing 100, an insert groove 130 is provided within the pump housing 100. This allows the circuit board 300 to be inserted along the insert groove 130 and secured. It is important to note that, since the USB Type-C socket 310, DC round-head socket 320, start switch 330, and indicator light 340 are all soldered onto the circuit board 300, and these components all need to protrude from the side wall of the pump housing 100, the circuit board 300 needs to be inserted at an angle along the insert groove 130 when inserted into it. This ensures that the USB Type-C socket 310, DC round-head socket 320, start switch 330, and indicator light 340 can ultimately protrude from their respective holes in the pump housing 100.

[0039] like Figure 4 and Figure 5 As shown, in one embodiment, the end opening of the insert groove 130 near the centrifugal fan 200 is also provided with a locking block 400, which is engaged with the circuit board 300 and abuts against the centrifugal fan 200.

[0040] It should be noted that a locking block 400 is provided at the opening of the insert groove 130 to fix the circuit board 300. For example, the locking block 400 is adapted to be embedded between the inner side wall of the pump housing 100 and the two first fixing posts 120, so that the locking block 400 can only be pulled out or inserted along the axial direction of the pump housing 100, and cannot move laterally. A slot 410 is provided on the side of the locking block 400 near the circuit board 300, so that the edge of the circuit board 300 is adapted to be inserted into the slot. Thus, when the volute 210 is fastened and fixed to the pump housing 100, the volute 210 abuts against the locking block 400, and the locking block 400 is fixed along the axial direction of the pump housing 100, that is, the locking block 400 is completely locked and fixed. Furthermore, the inner bottom wall of the pump housing 100 is provided with a limiting groove for locking the edge of the circuit board 300, so that when the circuit board 300 slides in along the insert groove, one edge of the circuit board 300 is finally locked and fixed by the limiting groove, and the other edge of the circuit board 300 is locked and fixed by the slot 410 of the locking block 400. Therefore, the circuit board 300 is reliably fixed and installed in the pump housing 100.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
