In view of this, the utility model is for the disappearance of prior art existence, and its fundamental purpose provides a kind of liquid level sensor of urea box, and it can effectively solve the not good problem of cold water Water pipe heating performance of existing liquid level sensor of urea box.
For achieving the above object, the utility model adopts following technical scheme:
A kind of liquid level sensor of urea box is used for being installed in urea box, the electron tube, urea tube and the cooling water pipe that include holder and can stretch into urea box inside; This electron tube and urea tube are installed on the holder, this electron tube is set with outward can be along the up and down floating drum of electron tube, the water inlet of this cooling water pipe and water delivering orifice all are installed on the holder, this cooling water pipe has back-shaped section and spiral section, this urea tube has at least the wall of a part of wall and back-shaped section to fit, and this spiral section is located in the outside of end opening under the urea tube.
As a kind of preferred version, described cooling water pipe includes the first vertical section, second vertical section and aforementioned back-shaped section and said spiral section, this first vertical section, back-shaped section, vertically section successively connection of spiral section and second.
As a kind of preferred version, described back-shaped section vertical the extension arranges, and this spiral section is positioned at back-shaped section below.
As a kind of preferred version, described spiral section is spiral extension vertically.
As a kind of preferred version, the lower ending opening of described urea tube is connected with filter screen, and this spiral section bag is located at the periphery of this filter screen.
As a kind of preferred version, described urea tube is fitted with the cooling water pipe binding by spring or heat shrinkage film.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
By back-shaped section and spiral section are set, the distance that can prolong the cooling water flow warp on the one hand, so that the heat of chilled water is fully used, heating properties is better, on the other hand, utilize back-shaped section can melt the urea crystals of the body inside of urea tube, to guarantee that urea liquid is carried unobstructed in the body, the heat that utilizes spiral section to discharge can melt near the urea crystals in the end opening under the urea tube and the lower ending opening, to guarantee that urea liquid enters in the urea tube smoothly, thereby guarantee that the urea liquid conveying is normal, stop the generation that urea crystals is blocked the phenomenon of urea tube.
For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
