The following describes the present invention with reference to the accompanying 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 related to 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 utility model provides a miniature water pump device of motor, wherein miniature water pump device of motor includes a water pump main part 10, water pump main part 10 includes a water inlet 11 and a delivery port 12, water inlet 11 with the work of drawing water and drainage is accomplished to delivery port 12.
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.
