Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more specifically, to a heatable diesel filter. Background Art

[0002] Currently, the oil used in automobiles is generally filtered through a filter, whose function is to remove impurities such as dust and tiny metal particles in the oil to protect the operation of the engine. However, in winter, some types of diesel are prone to icing and wax separation, resulting in insufficient fuel supply. In severe cases, the vehicle is difficult to start or even stalls during operation.

[0003] The Chinese utility model with the publication number CN202768199U in the prior art discloses a heatable diesel filter. Before the engine starts, the wire is energized, and the wire quickly heats up. Through heat conduction, the diesel condensed in this filter is indirectly heated to thaw the diesel in this filter. However, the wire is exposed externally, and it is easy to contact with other components during the heating process, resulting in damage to other components and thus generating potential safety hazards. In addition, only heating through the wire will cause uneven heating of the diesel in the center and the diesel on the outside, resulting in incomplete thawing and still easily affecting the starting of the vehicle. Therefore, this application proposes a heatable diesel filter. Summary of the Utility Model

The first heating wire 10 of the present invention is arranged to further heat and thaw the diesel, preventing the situation of incomplete thawing of the diesel. The sealing shell 3 of the present invention is arranged to wrap the first heating wire 10, thus preventing the first heating wire 10 from directly contacting the rest of the vehicle, making it safer to use.

[0030] As Figure 1 As shown, the ports of the first heating wire 10 and the second heating wire 16 respectively pass through the corresponding sealing shell 3 and the oil inlet passage 8 and are electrically connected to the power supply part. An annular fixing plate 101 is fixedly arranged at the upper end of the bottom shell 1. An annular groove 102 is provided on the outer side of the annular fixing plate 101. A sealing ring 103 is embedded in the annular groove 102. An annular fixing groove 201 is provided at the position of the top cover 2 corresponding to the annular fixing plate 101. The annular fixing plate 101 is clamped in the corresponding annular fixing groove 201.

[0031] With the above settings, the heating wire 10 and the heating wire 16 of the present utility model are electrically connected to the power supply unit, enabling the heating wire 10 and the heating wire 16 to be turned on and off; the annular fixing plate 101 and the sealing ring 103 of the present utility model enhance the sealing performance between the bottom shell 1 and the top cover 2, effectively preventing diesel leakage; the perforation 301 of the present utility model allows the sealing shell 3 to wrap around the outside of the bottom shell 1, serving to wrap the heating wire 10; the central tube 6 and the filter paper 15 of the present utility model serve to filter impurities in the diesel; the high-elastic spring 13 of the present utility model has an upward elastic force that presses, serving to fix the filter element upper cover 4, the filter element structure, the filter element lower cover 5, and the sealing cover plate 9, causing the components to press against each other and preventing diesel from leaking through the gaps between the components.

[0032] Working principle: When in use, the heating wire 10 and the heating wire 16 are turned on. Diesel enters through the oil inlet passage 8 and flows along the spiral fin 7. During the flow, the heating wire 16 heats the spiral fin 7, enabling all the diesel flowing through the spiral fin 7 to be uniformly heated and thawed. After the first heating and thawing, the diesel enters the central tube 6 through the oil inlet 11. Due to the heating of the heating wire 10, the interior of the housing is at a certain temperature, so the diesel can be further heated to further thaw it, preventing incomplete thawing. The thawed diesel can pass through the filter holes 601 of the central tube 6 and the filter paper 15, and then be discharged through the oil outlet passage 14. With the setting of the sealing shell 3, the heating wire 10 is not in a naked state, so it is safer to use. The filter paper 15, the central tube 6, the heating wire 10, the heating wire 16, the power supply unit, and their electrical connection methods of the present utility model are all modifications of existing technologies, so they will not be elaborated further.
