Description
TECHNICAL FIELD
[0001] The utility model relates to electronic water pump technical field, in particular to an electronic water pump structure with expansion capacity. BACKGROUND
[0002] The traditional electronic water pump (whether radial magnetic flux or axial magnetic flux electronic water pump) is a motor plus a impeller structure, and the power of the motor is used to drive the only impeller. Each impeller has a single inlet and outlet, and this structure causes the water pump to only work in a branch of the system, and if there are multiple branches, an electronic water pump must be set for each branch. Therefore, the traditional electronic water pump structure can only provide power for a single branch with a single pump, which limits the application range of the pump to a certain extent and also limits the development of the performance of the pump to higher technical requirements. In addition, the existing water pump also has a structure of one impeller, one inlet and multiple outlets. Due to the multiple outlets being at the same position, it is impossible to ensure that the flow of each outlet is the same, and therefore the water output is uneven, resulting in uneven water supply in different branches and affecting the normal work of the subsequent branches. SUMMARY
[0003] The technical problem to be solved by the utility model is that in order to overcome the deficiencies in the prior art, the utility model provides an electronic water pump structure with expansion capacity, which sets a set of impeller system on the other end of a single pump based on a single pump, so that the single pump has two sets of inlet and outlet systems and can be applied to two branch systems.
[0004] The technical scheme adopted by the utility model to solve the technical problem is that an electronic water pump structure with expansion capacity comprises an upper cover, a lower cover, a first impeller, a second impeller, a central pivot shaft and a motor assembly, the upper cover and the lower cover are mutually buckled to form a pump cavity inside, the motor assembly is arranged in the middle of the pump cavity, the pump cavity is divided into an upper liquid cavity and a lower liquid cavity, the first impeller is arranged in the upper liquid cavity, the second impeller is arranged in the lower liquid cavity, the central pivot shaft penetrates the motor assembly up and down, the upper end is connected with the first impeller, and the lower end is connected with the second impeller, the middle part of the upper cover is provided with a first inlet extending upward, the side surface of the upper cover is provided with a first outlet extending tangentially along the outer edge of the upper cover, and the first inlet and the first outlet are both communicated with the upper liquid cavity; the middle part of the lower cover is provided with a second inlet extending downward, the side surface of the lower cover is provided with a second outlet extending tangentially along the outer edge of the lower cover, and the second inlet and the second outlet are both communicated with the lower liquid cavity.
[0005] Furthermore, to facilitate reliable connection between the inlet / outlet and other pipelines, a first protruding ring is provided on the outer wall of the first inlet, a second protruding ring is provided on the outer wall of the second inlet, a third protruding ring is provided on the outer wall of the first outlet, and a fourth protruding ring is provided on the outer wall of the second outlet. The protruding rings on the inlet / outlet ensure a tighter connection between the port and external pipelines, thereby guaranteeing reliability.
[0006] Furthermore, to improve the stability of the inlet and prevent vibration under liquid impact, multiple first reinforcing ribs are provided circumferentially between the first inlet and the outer wall of the upper cover, and multiple second reinforcing ribs are provided circumferentially between the second inlet and the outer wall of the lower cover. These reinforcing ribs improve the reliability of the connection, thereby ensuring the stability of the inlet and reducing noise caused by vibration.
[0007] Furthermore, a first conical section is provided between the first outlet and the upper cover, and a second conical section is provided between the second outlet and the lower cover. The gradually increasing inner diameter of the conical section at the outlet position ensures timely discharge of liquid from the pump, preventing excessive water pressure on the pump components and potential damage.
[0008] Furthermore, to facilitate the connection between the motor and an external controller, a first connector is provided on the lower cover. The first connector has a terminal inside, and one end of the terminal is electrically connected to the motor assembly.
[0009] Furthermore, the system also includes a controller, one side of which has a second connector that is pluggably adapted to the first connector. The controller is pluggably connected to the lower cover via the second connector and is electrically connected to the motor assembly. The pluggable connection of the controller to the water pump housing facilitates easier connection and disassembly.
[0010] The beneficial effects of this utility model are as follows: This utility model provides an electronic water pump structure with expandability, which uses a bidirectional output motor as the power component. Based on the original single impeller, an additional impeller is added to form two sets of symmetrical structures. Each set of inlet, impeller, and outlet can correspond to a branch, and the two sets of impeller structures do not interfere with each other. Compared with a single multi-outlet water pump structure, the flow rate of each outlet of this electronic water pump is basically the same, which can ensure the same flow rate in different branches. Compared with using multiple water pumps, it can greatly reduce costs while ensuring multi-channel water supply. Attached Figure Description
