Electric heating type urea liquid level sensor

Abstract

The invention discloses an electric heating type urea liquid level sensor. The urea liquid level sensor comprises an upper base, wherein a power line is fixedly connected to the upper end of the upperbase, handles are installed on the front portion and the rear portion of the upper base through connecting mechanisms, the handles are each of a U-shaped structure, a sensor assembly, a liquid guidepipe and a heating pipe are fixedly connected to the lower end of the upper base, a heat conduction mechanism is arranged on the heating pipe, and the lower end of the upper base is connected with a mounting pipe through mounting mechanisms. According to the urea liquid level sensor, the heat conduction mechanism is arranged on the heating pipe, a fixing pipe of the heat conduction mechanism is arranged outside the heating pipe in a sleeving mode, the fixing pipe is further connected with a spiral pipe, and heat conduction oil fills the interior of the spiral pipe and the interior of a transition pipe; during use, the heat conduction oil in the fixing pipe and the spiral pipe is heated through the heating pipe, then the fixing pipe and the spiral pipe are heated through the heated heat conduction oil, urea liquid frozen in a urea box is heated and unfrozen, the heating area is increased, and then the unfreezing speed is increased.

Description

technical field [0001] The invention relates to an electric heating type urea liquid level sensor, belonging to the technical field of urea liquid level sensors. Background technique [0002] The urea liquid level sensor is one of the parts installed on the urea tank of the car. It is used to detect the amount of urea liquid inside the urea tank. At the same time, it can heat the urea to prevent the urea liquid from freezing and cannot be sprayed out. The sensor is a type of urea level sensor. [0003] At present, most electric heating urea level sensors installed on automobiles are directly inserted into the urea solution in the urea tank. The urea solution will corrode the heating components of the electric heating urea level sensor and shorten the use of the electric heating urea level sensor. life, and needs to be replaced as a whole when damaged, the cost is high, and it is impossible to heat and thaw other frozen urea solutions in the urea tank in time, the thawing sp...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an electric heating type urea liquid level sensor, which effectively solves the problem that most electric heating type urea liquid level sensors installed on automobiles are directly inserted into the urea liquid in the urea tank, and the urea liquid will corrode the electric heating type urea. The heating component of the liquid level sensor shortens the service life of the electric heating urea liquid level sensor, and needs to be replaced as a whole when damaged, the cost is high, and it cannot be heated and thawed in time for other frozen urea liquid in the urea tank, and the thawing speed is slow , and it has been installed for a long time, the surface of the upper seat of the electric heating urea level sensor will be covered with foreign matter, which is more troublesome when disassembling
