Abstract
A liquid pump device sucking and discharging liquid includes: a pump unit 50, rotating to make the liquid flow; a housing H, accommodating the pump unit and defining a passage 14 of the liquid; and a temperature sensor 80 having a tip region 80a protruded in the passage 14 of the liquid to measure a temperature of the liquid flowing on the passage 14.
Claims18
A liquid pump device, comprising:
- a pump unit, rotating to make liquid flow;
- a housing, accommodating the pump unit and defining a passage of the liquid;
- and
- a temperature sensor having a tip region protruded in the passage, so as to measure a temperature of the liquid flowing on the passage, wherein the temperature sensor comprises:
- a cylindrical member that is bottomed and inserted into the passage;
- and a sensor element disposed at a tip region inside of the cylindrical member, and the temperature sensor is disposed in a manner that the liquid flowing on the passage collides with the tip region of the cylindrical member, and
- the cylindrical member comprises a small diameter part accommodating the sensor element and a surrounding wall part formed to be curved so as to partially surround a periphery of the small diameter part,
- wherein the passage comprises a first linear passage and a second linear passage intersecting and communicating with the first linear passage, and the surrounding wall part is formed by a resin material and formed to be curved in a manner that a region opposite to the second linear passage is cut off to partially surround the periphery of the small diameter part.
