[0002] With the development of battery technology, many power components can now be directly driven by battery packs. However, existing DC battery-driven motors only have this one type of drive, which is limited by usage time and power. AC motors, on the other hand, require AC lines and have high environmental requirements. Furthermore, some motors that can switch between AC and DC are cumbersome to switch between, and connecting AC connectors while using DC power poses safety risks. Existing motors cannot be driven by both DC and AC power, or they lack the ability to quickly and automatically switch between AC and DC power. Motors that can drive simultaneously cannot connect to both DC components and AC connectors at the same time, making them very troublesome to use, cumbersome to operate, and requiring many precautions.

[0019] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0020] Combined with appendix Figure 1-5 A universal AC / DC pump includes a support base 1, a housing 2 on the support base 1, the housing 2 being fixed to the support base 1, and a cavity containing multiple accommodating components inside the housing 2. A partition is provided between the multiple cavities to divide the multiple cavities into independent spaces. The internal space of the housing 2 includes a bottom cavity covering the bottom surface of the housing 2, and a first cavity, a second cavity, and a third cavity arranged sequentially inside the housing 2 and on the bottom space. The second cavity is located between the first cavity and the third cavity.

[0021] An adapter 3 is fixedly installed inside the bottom cavity. Both DC and AC power supplies are directly connected to the adapter 3. The adapter 3 can switch the working mode according to the voltage of the connected power supply, so that both AC and DC power can drive the motor 6. The adapter 3 is used to adjust the voltage and current of the obtained DC and AC power according to the motor 6 to facilitate the use of the motor 6.

[0022] On the side of the bottom cavity away from the adapter 3, there is also a power cord 4 and a quick-connect interface. The quick-connect interface is fixed to the power cord 4. The power cord 4 is folded and stored with a storage strap. When AC power is not in use, the power cord 4 and the quick-connect interface can be bundled together with the storage strap and then placed in the bottom cavity for safe storage. This does not occupy external space and protects the power cord 4 and the quick-connect interface. The outer shell 2 can be provided with a freely opening and closing cover on the side of the bottom cavity on the same side as the power cord 4 for easy access and use.

[0023] A locking block can be installed in the bottom cavity at the position for installing the power cord 4, which can lock the power cord 4, after being bound by the storage strap, onto the locking block, thereby making it easy to fix the power cord 4.

[0024] A battery pack 5 is installed in the first cavity located on the upper side of the bottom cavity. The battery pack 5 is installed in the first cavity by means of a plug-in card. The first cavity is provided with a plug-in plate structure that is compatible with the battery pack 5. The first cavity can accommodate at least one battery pack 5, preferably at least two battery packs 5 are plugged into the first cavity, so that the motor 6 can work reasonably for as long as possible. The battery pack 5 is directly electrically connected to the adapter 3. The adapter 3 can adjust the voltage and current output by the battery pack 5 to power the motor 6.

[0025] Electrode plates are provided on the plug-in plate inside the first cavity, and electrode plates are also provided on the battery pack 5. When the battery pack 5 is installed in the first cavity, it is inserted into the plug-in plate of the first cavity in the correct position. When the battery pack 5 moves to a state where it cannot move further in the plug-in plate, the electrode plates on the battery pack 5 abut against the electrode plates on the plug-in plate, while the electrode plates on the plug-in plate remain connected to the adapter 3. When the electrode plates on the battery pack 5 abut against the electrode plates on the plug-in plate, the battery pack 5 can transmit the stored electrical energy to the adapter 3. At this time, the adapter 3 processes the DC power output from the battery pack 5 and transmits it to the motor 6, thereby causing the motor 6 to drive the water pump.

[0026] The shape of the partition on the sidewall of the first cavity can be designed to correspond to the shape of the side of the battery pack 5. When the battery pack 5 is in close contact with the partition, it can be aligned with the plug-in plate in the first cavity, facilitating the movement of the battery pack 5 within the plug-in plate. This allows the user to easily determine the installation position of the battery pack 5 by observing the shape of the partition, thereby improving the accuracy and speed of battery pack 5 installation. Preferably, the shapes of the battery pack 5 and the partition are designed as corresponding grooves and protrusions, respectively, making it easy for the user to mate the battery pack 5 and the partition to determine the installation position of the battery pack 5 and the plug-in plate.

[0027] A latch can be installed in the first cavity, corresponding to the connector plate. The latch locks the battery pack 5 onto the connector plate in the first cavity, preventing accidental movement of the battery pack 5. If the electrode plates on the battery pack 5 lose connection with the electrode plates on the connector plate, power transmission will be interrupted, affecting the operation of the motor 6. The latch can be a direct-insertion pin-type latch or a snap-on type latch. By setting the locking body and latch tongue in the first cavity and providing a corresponding locking groove on the battery pack 5, the latch can firmly fix the battery pack 5 to the connector plate after it is installed in place. This locks and fixes the battery pack 5, preventing it from moving during use and ensuring the stable operation of the motor 6. To remove the battery pack 5, simply unlock the latch and remove the battery pack 5 from the connector plate in the first cavity; it is very convenient.

[0028] A motor 6 is fixedly installed inside the second cavity. The motor 6 is preferably a brushless motor, ensuring high-speed output. A bracket for mounting the motor 6 is provided inside the second cavity. A flange for connection can be fixed to the motor 6, securing it to the bracket. The bracket can be made of aluminum, ensuring pump body strength while reducing pump weight for easy carrying and transportation. The flange of the motor 6 is fixed to the bracket via a threaded connection.

[0029] The third cavity is sealed to the second cavity. A pump body flow channel 7 is provided in the third cavity. The seal between the second cavity and the third cavity can protect the motor 6, thereby preventing the liquid in the pump body flow channel 7 from flowing into the second cavity and affecting the electrodes, thus reducing the service life of the motor 6.

[0030] A sealing cover plate is provided on the pump body flow channel 7. The sealing cover plate can serve as a partition to isolate the second cavity and the third cavity. The sealing cover plate is fixed to the pump body flow channel 7, and can also be sealed and fixed to the pump body flow channel 7 by means of threaded engagement. The flow channel structure inside the pump body flow channel can be adaptively designed according to requirements.

[0031] The output shaft of the motor 6 installed in the second cavity extends into the pump body flow channel 7. An impeller 8 is fixedly mounted on the output shaft. The impeller 8 rotates at high speed following the output shaft of the motor 6, thereby enabling the pump to transport liquids or gases. The pump body flow channel 7 is equipped with an inlet pipe interface and an outlet pipe interface. The positions of the inlet and outlet pipe interfaces can be strategically arranged according to the application scenario of the pump, thereby expanding the application scenarios of the pump. A guide plate is provided in the pump body flow channel 7. The guide plate can control the flow direction of the liquid or gas entering the pump body flow channel 7, so that the gas or liquid flows from the inlet pipe interface to the outlet pipe interface, thereby realizing the transportation of liquids or gases. The sides of the inlet and outlet pipe interfaces are also equipped with valve covers 9. Multiple sets of inlet and outlet pipe interfaces can be installed on the pump body flow channel 7. The valve covers 9 can block unused inlet and outlet pipe interfaces, giving users more options. Multiple sets of inlet and outlet pipe interfaces can be set in different positions on the pump body or with different inner diameters, making it convenient for users to adjust according to their own needs.

[0032] A control display board 10 is fixedly installed on the outer casing 2. The control display board 10 can integrate a power toggle switch, a timer button 22, a speed control button 21, a fault alarm indicator 13, a speed gear digital display light 14, a toggle switch 15, a control indicator light 18, a power indicator light 19, a timer digital display light 20, a DC indicator light 17, and an AC indicator light 16. This allows users to quickly control the pump body using the control display board 10 and intuitively observe the pump's operating parameters, making it very convenient and efficient.

[0033] The toggle switch can further control the function type selected by the adapter 3, and is used to manually control the DC power supplied by the battery pack 5 and the AC power supplied by the quick-connect interface of the power cord 4, so as to further determine the function type that the user wants to use, and can also serve as a further confirmation function to prevent accidents from happening.

[0034] The outer casing 2 has a rotatable battery box cover 11 on the upper side of the first cavity, which facilitates the installation and protection of the battery pack 5. When the battery box cover 11 is opened, the outer casing 2 has an opening on the upper side of the battery pack 5, allowing the user to remove or install the battery pack 5. When the battery box cover 11 is fastened to the outer casing 2, the outer casing 2 forms a sealed whole, thereby protecting the pump body and preventing the internal components of the pump body from coming into contact with the external environment when the pump body is working, thus affecting the normal operation of the pump body.

[0035] A handle 12 is also rotatably mounted on the outer casing 2, which makes it convenient for users to lift the pump body by means of the handle 12. The outer casing 2 may also have a groove to accommodate the handle 12, so that the handle 12 will not be too obtrusive on the outer casing 2.

[0036] In other embodiments, adapter 3 can automatically identify AC and DC power supplies. When the power cord 4 and quick-connect interface are removed from the housing 2, the quick-connect interface can be electrically connected to the AC power supply, thus enabling adapter 3 to recognize AC power. After recognizing AC power, adapter 3 prioritizes the use of AC power, ensuring that the pump can operate at high power for extended periods. When AC power is not in use, the battery box cover 11 is opened, and the installation package is inserted into the plug-in plate in the first cavity. At this time, adapter 3 directly adjusts the DC power output from the battery pack 5 to a voltage and current suitable for the motor 6, enabling the motor 6 to operate.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. 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.
