Problems solved by technology
[0002] Most of the existing electronic water pumps do not have an anti-electromagnetic interference module, so the control board components are easily unable to achieve normal commutation of the current due to the influence of electromagnetic interference
As an improvement, an anti-electromagnetic interference module can be added to the electronic water pump. However, since the anti-electromagnetic interference module needs to occupy a certain installation space, it will lead to a larger volume of the electronic water pump.

Embodiment Construction
[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0027] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

The invention discloses an electronic water pump, which comprises a pump shell, a motor shell, an end cover, a stator assembly, a rotor impeller assembly, a control panel assembly and an anti-electromagnetic interference module. A pump cavity is formed by the end cover and the pump shell. A motor cavity is formed by the end cover and the motor shell. The stator assembly is arranged in the motor cavity. An installation cavity is formed in the stator assembly. The rotor impeller assembly comprises a rotating shaft, an impeller and a rotor, wherein the impeller and the rotor are sleeved onto therotating shaft. The impeller is arranged in the pump cavity. The rotor is arranged in the motor cavity. The rotor is arranged on the outer side of the stator assembly in the radial direction. The anti-electromagnetic interference module is arranged in the installation cavity. The anti-electromagnetic interference module is electrically connected with the control panel assembly. According to the invention, the anti-electromagnetic interference module is arranged in the installation cavity inside the stator assembly, so that the internal space of the stator assembly can be effectively utilized.Therefore, on the basis that the anti-electromagnetic interference function of the electronic water pump is realized, the miniaturization of the electronic water pump can be kept.
Description
Technical field [0001] The invention relates to the field of water pumps, in particular to an electronic water pump. Background technique [0002] Most of the existing electronic water pumps do not have an anti-electromagnetic interference module. Therefore, the control board components thereof are prone to be unable to achieve normal commutation of current due to the influence of electromagnetic interference. As an improvement, an anti-electromagnetic interference module can be added to the electronic water pump. However, since the anti-electromagnetic interference module needs to occupy a certain installation space, the electronic water pump will have a larger volume. Summary of the invention [0003] The main purpose of the present invention is to provide an electronic water pump, which aims to reduce the volume of the electronic water pump. [0004] In order to achieve the above objective, the electronic water pump proposed by the present invention includes: a pump housing, a m...
