Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-2, the present invention provides a motor micro water pump device, wherein the motor micro water pump device includes a water pump main body 10, the water pump main body 10 includes a water inlet 11 and a water outlet 12, and the water inlet 11 and the water outlet 12 perform water pumping and water discharging operations.

The motor miniature water pump device is characterized in that a motor base 13 is arranged inside the water pump main body 10, the motor miniature water pump device further comprises a motor 20, and the motor 20 can be installed on the motor base 13. The water pump main body 10 includes a main diaphragm 30, and the main diaphragm 30 forms two cavities including a first cavity 31 and a second cavity 32, hereinafter referred to as a cavity a and a cavity B. Two cavities are formed, so that the volume of the inner cavity of the water pump main body 10 is increased, and meanwhile, the main diaphragm 30 is made of elastic materials and can deform to change the volumes of the cavity A and the cavity B, so that the flow of the pump body is increased.

The first chamber 31 has a first water inlet 311 and a second water outlet 312, the second chamber 32 has a second water inlet 321 and a second water outlet 322, wherein the first water inlet 311 and the second water inlet 321 are connected to the water inlet 11, and the first water outlet 312 and the second water outlet 322 are connected to the water outlet 12.

The motor miniature water pump device further comprises an eccentric wheel 40 and a propeller 50, wherein the eccentric wheel 40 is electrically connected with the motor 20, the motor 20 can drive the eccentric wheel 40, the eccentric wheel 40 drives the propeller 50 to rotate, and the propeller 50 drives the main diaphragm 30. The propeller 50 induces a deformation in the main diaphragm 30 such that the main diaphragm 30 induces a change in the a and B chambers.

Further, the micro water pump device of the motor is installed by firstly installing the eccentric wheel 40 on the motor 20, and fixedly installing the motor 20 and the motor base 13 through a motor locking screw. The size of the eccentric 40 can be greatly reduced so that the eccentric 40 can be directly mounted to the motor 20 without the need for a nipper attachment. An inner bracket 14 is arranged inside the water pump main body 10, a certain gap exists between the inner bracket 14 and the eccentric wheel 40, and the existence of the gap ensures that the motor micro water pump device can always keep running under the condition of low voltage.

The specific working principle is as follows:

in the water inlet stage, when the motor 20 is powered on, the motor 20 drives the eccentric wheel 40 to rotate, the eccentric wheel 40 drives the propeller 50 to rotate, and the propeller 50 increases the volumes of the cavity a and the cavity B (the cavity a and the cavity B are formed by the main diaphragm 30). At this time, the pressure inside the cavity of the water pump body 10 is lower than the pressure at the water inlet 11, and water flows into the water inlets of the cavity a and the cavity B from the water inlet 11 respectively.

In the water outlet stage, the motor 20 drives the eccentric wheel 40 to rotate, the eccentric wheel 40 drives the propeller 50 to rotate, and the propeller enables the volumes of the cavity A and the cavity B to be reduced. At the moment, the pressure in the cavity is larger than the pressure at the water outlet, and water flows out of the water outlets from the water outlets of the cavity A and the cavity B.

In the working stage, the A cavity and the B cavity are deformed, so that the pump body finishes the water pumping and draining operation.

The water inlet 11 is provided with a one-way check valve which is allowed to open in the water inlet direction, and the water outlet 12 is provided with a one-way check valve which is allowed to open in the water outlet direction. The pump core 20 moves and changes the volume of the water storage bin, thereby causing the opening and closing of the one-way check valve 40 to complete the pumping operation.

Further, the present embodiment further includes a diaphragm and a pump core seat, the pump core is mounted on the pump core seat 21, and the diaphragm is disposed at one end of the pump core. The pump core seat is provided with a pressurizing structure which is communicated with the water inlet 11, so that the flow of water entering from the water inlet is stable, and the current water outlet pressure is kept stable. On the other hand, the pressure boost structure is triangle-shaped increases the structure, when the pressure boost structure sets up when the water inlet, can increase the pressure of intaking.
