Urea is a substance having a reducing property, and can undergo an oxidation-reduction reaction with nitrogen oxides to reduce the nitrogen oxides into nitrogen gas, and is often used for the exhaust gas treatment of automobiles. Since the melting point of standard urea aqueous solution used for vehicle exhaust treatment is about-11 ℃, urea is often frozen in low temperature environments such as winter.
In the related art, a heating device is provided in a urea tank. After the heating device heats the urea, a cavity containing liquid urea is formed in the frozen urea. But the frozen urea cuts off the cavity and other cavities in the urea box body, so that the urea liquid level measured by the liquid level sensor positioned at the heating device can not effectively represent the actual urea liquid level height in the urea box body after urea filling, and the accuracy of the urea endurance mileage calculated based on the urea liquid level height is poor.
Based on the problem, in order to solve the problem of how to improve the accuracy of the urea endurance mileage, the application provides a urea device, a urea system and a vehicle. The length value of the heating module in the urea liquid level height direction is larger than or equal to the maximum urea liquid level height value of the accommodating cavity. When the heating module heats the frozen urea, the heating module forms a cavity which penetrates through the frozen urea and contains the liquid urea in the frozen urea. One end of the cavity is communicated with the other cavities of the accommodating cavity, so that the injected urea can flow into the cavity in the frozen urea, and therefore, the liquid level sensor positioned in the area where the heating module is positioned can effectively measure the liquid level of the urea, and the accuracy of the urea endurance mileage is improved. The method specifically comprises the following steps:
The first aspect of the present application proposes an embodiment, as shown in the schematic structural diagram of a urea plant shown in fig. 1, the urea plant includes:
The urea box body 1 is provided with a containing cavity 11 for containing urea;

The liquid level sensor 3 is arranged in the accommodating cavity 11, and the liquid level sensor 3 is positioned in the area where the heating module 2 is positioned.
The urea device comprises a urea box body 1, a heating module 2 and a liquid level sensor 3. The urea box 1 is provided with a containing cavity 11 for containing urea. The urea box body 1 is also provided with a urea filling port 12 communicated with the accommodating cavity 11, and can be arranged at the top of the urea box body 1 for filling urea so as to supplement the urea in the accommodating cavity 11 under the condition of insufficient endurance mileage of the urea.
The heating module 2 is arranged in the receiving chamber 11. In operation, the heating module 2 continuously outputs heat outwards, thereby melting frozen urea. The length value of the heating module 2 in the urea liquid level height direction is larger than or equal to the maximum liquid level height value of the accommodating cavity 11. The heating module 2, when melting frozen urea, forms a cavity in the frozen urea containing liquid urea. The cavity has an opening at the top of the frozen urea, so that the cavity communicates with the remaining ones of the receiving chambers 11 through the opening. The rest cavities refer to the cavities except the cavity and the frozen urea in the accommodating cavity 11. In an alternative embodiment, the heating module 2 may be a heating rod made of PTC (Positive Temperature Coefficient ) thermistor.
The liquid level sensor 3 is arranged in the accommodating cavity 11 and is positioned in the area where the heating module 2 is positioned, so that the urea liquid level in the area where the heating module 2 is positioned is detected.
When the urea in the urea tank 1 freezes, the heating module 2 starts to operate, forming a cavity in the frozen urea containing liquid urea. In the running process of the vehicle, as the urea is consumed, the liquid urea in the cavity is reduced, and when the liquid level of the liquid urea is reduced to a preset liquid level, urea filling is needed to be carried out so as to supplement the urea.
When urea is added, as the opening of the cavity at the top of frozen urea communicates the cavity with the rest cavities of the accommodating cavity 11, urea entering the accommodating cavity 11 can flow into the cavity from the rest cavities of the accommodating cavity 11, so that newly added urea can be reflected in the urea liquid level acquired by the liquid level sensor 3, the urea liquid level is effectively measured, and the accuracy of urea endurance mileage is improved.

One end of the heating pipe 21 is connected with the urea box body 1, and the length value of the heating pipe 21 in the urea liquid level height direction is larger than or equal to the maximum urea liquid level height value of the accommodating cavity 11, so that one end of the heating pipe 21 far away from the urea box body 1 is higher than the top of frozen urea.
Optionally, at least one through hole 23 is provided on the pipe wall of the heating pipe 21, and the at least one through hole 23 is located at one end of the heating pipe 21 near the bottom of the urea tank 1.

At least one through hole 23 is located at one end of the heating pipe 21 near the bottom of the urea box 1, so as to communicate the lumen of the heating pipe 21 with the outer area of the heating pipe 21, so that urea in the lumen and the outer area of the heating pipe 21 can freely circulate, and the full utilization of lumen space is realized.
Alternatively, the liquid level sensor 3 includes an ultrasonic liquid level sensor 31 or a float type liquid level sensor 32.
Referring to fig. 1 and 3, there is shown a schematic structural diagram of a urea device of a float-type liquid level sensor. The liquid level sensor 3 may comprise an ultrasonic liquid level sensor 31 or a float-type liquid level sensor 32.

The float 322 is made of a material having a density smaller than that of urea, and is freely movable along the length direction of the float rod 321 with the rise or fall of the urea liquid level on the float rod 321.
As the urea level rises, a float 322 that floats on the urea level moves upward as the urea level rises; when the urea level decreases, the float 322 floating on the urea level moves downward with the decrease of the urea level, so that the urea level can be obtained by measuring the position of the float 322.
