Description

Technical Field

[0001] The present invention belongs to the technical field of urea filling machines, and particularly relates to a heating mechanism of a urea filling machine with an energy-saving function. Background Art

[0002] Many heavy-duty trucks often use diesel engines to obtain greater power. The nitrogen oxides emitted by diesel engines directly discharged into the air will pollute the atmosphere. In order to avoid environmental pollution, people usually add urea solution inside the vehicle to make it chemically react with vehicle exhaust.

[0003] Since the vehicle urea solution will crystallize at -11°C, and the existing urea solution filling machines are generally exposed to the outside world, it is very easy to cause urea solution crystallization when used in a low-temperature environment, which is not convenient for people to use. Therefore, people will use a heating structure to heat the urea filling machine, so as to prevent the urea solution in the liquid storage cylinder and the liquid guide pipe from crystallizing due to too low temperature.

[0004] However, the heating mechanisms of existing urea filling machines can often only heat and keep warm the liquid storage cylinder and part of the liquid guide pipes located inside the filling machine, while part of the liquid guide pipes and the filling gun are located outside the filling machine and cannot be heated and kept warm. Therefore, the temperature of the above-mentioned liquid guide pipes and filling guns located outside the filling machine will be relatively low, resulting in a relatively low temperature of the urea solution remaining in the liquid guide pipes and filling guns located outside the filling machine, and further resulting in a relatively low temperature of the urea solution initially filled into the vehicle subsequently, which is likely to affect the normal use of the urea solution by people.

[0005] For example, the invention with the publication number CN 215403071 U discloses a crystallization-proof vehicle urea solution filling machine with a heat preservation function. In the technical solution of this patent, the filling gun and part of the filling pipes are located outside the filling machine, so the filling gun and part of the filling pipes are directly exposed to the air, resulting in a relatively low temperature, and further resulting in a relatively low temperature of the urea solution remaining in the filling gun and part of the filling pipes, and also resulting in a relatively low temperature of the urea solution flowing through the filling gun and filling pipes subsequently. Therefore, it is very easy to cause a malfunction in the working state of the vehicle filled with the above-mentioned urea solution with a relatively low temperature. Summary of the Invention

[0006] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a heating mechanism for a urea filling machine with energy-saving functions, which can not only quickly and efficiently heat and keep warm the urea solution in the liquid storage cylinder, but also heat and keep warm the filling gun and all the liquid guiding hoses, so that the filling gun and the liquid guiding hoses maintain corresponding temperatures, and the temperatures of the urea solutions in the liquid storage cylinder, the filling gun and the liquid guiding hoses are maintained at corresponding temperatures, so that the temperature of the filled urea solution is kept balanced, avoiding the need for users to heat the urea solution for a long time due to unbalanced temperature, thereby saving energy and better meeting the needs of people for using urea solution.
