Problems solved by technology

[0002] The quality detection device currently used in the urea tank includes a plastic head, a suction pipe, a liquid return pipe, an electronic tube, and a quality sensor. The suction pipe is used to suck out the urea solution, and the unused solution is returned to the urea tank through the return pipe. The returned solution is directly sprayed onto the urea solution. Due to the high pressure during the pressure release, the sprayed urea solution is prone to foaming when it directly hits the liquid surface. The generated bubbles will affect the accuracy of the liquid level detection by the quality detection device. When the air bubbles attached to the sensing area of ​​the quality sensor, it will cause reading deviation

Embodiment Construction

[0033] In order to describe the technical content and structural features of the present invention in detail, further description will be given below in conjunction with the implementation and accompanying drawings.

[0034] Such as figure 1 , figure 2 and Figure 4 As shown, the vehicle-mounted fluid storage tank of the present invention includes a tank body (not shown in the figure) and a quality detection device 10 installed in the tank body. In the present invention, the tank is a urea tank, which is used to store the urea solution, and the quality detection device 10 is used to detect the concentration of the urea solution. However, according to actual application requirements, the tank body can also be used as a fuel tank for storing fuel, so the actual use of the vehicle-mounted fluid storage tank is not limited.

[0035] Wherein, the quality detection device 10 of the present invention includes a mounting base 11 , a drainage tube 12 and a quality sensor 13 . The ...

Abstract

A quality detection device disclosed by the present invention comprises a mounting seat, a drainage tube and a quality sensor, the mounting seat is suitable for being mounted on a box body, the mounting seat is provided with a backflow hole, a first end of the drainage tube is in butt joint communication with the backflow hole, a second end of the drainage tube is mounted on the quality sensor, and the quality sensor is provided with a detection area for detecting the concentration of a solution. And the solution output by the second end of the drainage tube is used for spraying and washing the detection area of the quality sensor. The quality detection device can prevent the pressure relief solution from directly impacting the liquid level to generate bubbles, and can also scour the bubbles in the sensing area of the quality sensor. In addition, the invention further discloses a vehicle-mounted liquid storage tank.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a quality detection device and a vehicle-mounted liquid storage tank thereof. Background technique [0002] The quality detection device currently used in the urea tank includes a plastic head, a suction pipe, a liquid return pipe, an electronic tube, and a quality sensor. The suction pipe is used to suck out the urea solution, and the unused solution is returned to the urea tank through the return pipe. The returned solution is directly sprayed onto the urea solution. Due to the high pressure during the pressure release, the sprayed urea solution is prone to foaming when it directly hits the liquid surface. The generated bubbles will affect the accuracy of the liquid level detection by the quality detection device. When the air bubbles attached to the sensing area of ​​the quality sensor, it will cause reading deviation. [0003] Therefore, there is an urgent need for a quality detection...
