[0024] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Combined with attachment Figure 1-6, an AC / DC switching pump, used to enable the motor pump to be powered by both AC and DC power, expanding the conventional applicable environment of the motor pump, including a pump housing 10, a battery box 11 is provided in the pump housing 10, the battery box 11 is installed in the pump housing 10 by plugging, the pump housing 10 is layered to form two local spaces, one large and one small, the larger local space is used to connect the power supply, that is, for installing the battery box 11, the battery box 11 represents the DC power supply, and the smaller local space is provided with an adapter 12, the adapter 12 is used to adjust the power circuit of the motor pump, so that when AC and DC are switched as power supplies, the motor can be driven to rotate through the control of the adapter 12.

[0027] A plug board 13 is provided on the floor of the larger space inside the pump housing 10. The plug board 13 is used to cooperate with the battery box 11. When the battery box 11 is installed in the pump housing 10, the battery box 11 can be used as a power source by inserting it into the plug board 13, which is convenient and quick to use.

[0028] The plug board 13 is provided with a matching limit plate 131, which is symmetrically arranged on both sides of the plug board 13, and positive and negative contact pieces 132 are symmetrically arranged between the matching limit plates 131. After the positive and negative contact pieces 132 come into contact with the positive and negative contact holes led out of the battery box 11, electrical connection is achieved, thereby quickly forming a power supply circuit.

[0029] The outer surface of the bottom of the battery box 11 is provided with an electrode plug interface 14, which is composed of a matching slide 141 symmetrically arranged on both sides and a positive and negative electrode connection hole 142 located in the matching slide 142. The matching slide 141 is corresponding to the matching limit plate 131, and the positive and negative contact pieces 132 are corresponding to the positive and negative electrode connection holes 142. When the battery box 11 is required to be placed in the pump housing 10 for DC power supply, first insert the prepared battery box 11 into the pump housing 10, match the plug board 13 with the electrode plug interface 14, and match the slide 1 41 corresponds to the insertion of the matching limit plate 131. At this time, the battery box 11 is inserted into the pump housing 10. When the user sets the electrode plug interface 14, a certain friction force can be set between the matching slide 141 and the matching limit plate 131. When the matching slide 141 and the matching limit plate 131 slide together, a certain damping is provided to prevent the battery box 11 from accidentally withdrawing from the pump housing 10. Therefore, when the matching slide 141 is inserted into the matching limit plate 131, the battery box 11 can be fixed in the pump housing 10 by the friction force between the matching slide 141 and the matching limit plate 131.

[0030] When the mating slide 141 is inserted to the innermost side of the mating limit plate 131, the positive and negative contact pieces 132 of the plug-in board 13 are inserted into the positive and negative electrode holes 142 on the battery box 11, so that the positive and negative contact pieces 132 of the plug-in board 13 are fully in contact with the positive and negative electrode connectors in the positive and negative electrode holes 142. At this time, the positive and negative poles of the battery box 11 are connected to the positive and negative poles of the plug-in board 13, thereby forming a DC power supply.

[0031] The matching design of the positive and negative contact pieces 132 and the positive and negative contact holes 142 is convenient and stable, and the contact parts are not exposed to the outside and are very safe.

[0032] The battery box 11 can be optionally composed of a combination of battery packs 25. Preferably, separate 20V battery packs 25 are connected in series to form a 40V battery pack and installed in the battery box 11, and the positive and negative terminals of the formed 40V battery pack are connected to the positive and negative terminal holes 142 of the electrode plug interface 14 and extend to one end inside the battery box 11. The same effect can also be achieved by directly using a separate 40V battery pack.

[0033] A structure similar to the electrode plug interface 14 can be set on the battery pack 25 in the battery box 11, and a structure similar to the plug board 13 can be set at the position for installing the battery pack 25 in the battery box 11, so as to fix the battery pack 11 in the battery pack 25.

[0034] A power cord quick connect interface 15 is provided on one side of the plug board 13 in the pump housing 10, and a space for installing the power cord quick connect interface 15 is provided on the side of the space for installing the battery box 11 in the pump housing 10. The battery box 11 can completely cover the space of the power cord quick connect interface 15 after the battery box 11 is installed in the pump housing 10. The power cord quick connect interface 15 is used to connect AC power, so that the AC power connected to the power cord quick connect interface 15 can power the motor pump. The power cord quick connect interface 15 is preferably set to a plug shape that can be connected to AC power. The power cord quick connect interface 15 is blocked by the battery box 11 in the pump housing 11, so that the motor pump 11 is in use. When the DC power of the battery box 11 is used as the power source, the power cord quick connect interface 15 can no longer be connected to the pump housing 10 due to the obstruction of the battery box 11. When the AC power of the input power cord 20 needs to be used as the power source, the battery box 11 needs to be removed before the power cord quick connect interface 15 can be extended to the AC power source, which is generally a socket.

[0035] The power cord quick-connect interface 15 can be selected to be actively inserted into the outside or to be passively connected.

[0036] The above method realizes single-form energy supply of AC and DC, which is very safe.

[0037] A control panel 16 is provided on the pump housing 11. The control panel 16 includes a switch and a plurality of indicator lights for operating the motor pump.

[0038] A motor is provided on the side of the pump housing 10 , and the motor is driven by a battery box or an input power line 20 in the form of direct current or alternating current, and the electrodes drive the pump head to realize various functions.

[0039] The plug board 13 and the power cord quick-connect interface 15 are both electrically connected to the adapter 12, so that when the power supply is connected to the plug board 13 and the power cord quick-connect interface 15, the adapter 12 can automatically identify and control the current and voltage in the conversion circuit to power the motor.

[0040] When using AC power, the power cord quick-connect interface 15 forms a complete circuit with the adapter 12, the control board, and the motor.

[0041] When using direct current, the plug board 13, the adapter 12, the control board and the motor form a complete circuit.

[0042] Simple operation, sequential switching, and single drive mode are safer and more efficient.

[0043] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
