When the adjustment column 18 is in the first state, the second state and the third state, the vertical arm 29 is respectively engaged with the three groups of positioning protrusions 28, and both sides of the vertical arm 29 are in contact with the positioning protrusions 28. The outer end of the rotating sleeve 27 is provided with an operating handle 30, and the outer end of the operating handle 30 is provided with an operating disk 31.

[0054] The utility model provides a heating structure based on the inkjet printer. The structure of the present application is used to connect the ink cartridge with the ink supply system, and then the ink of the ink supply system enters the heating channel. At the same time, the heating element 2 (preferably electric heating, that is, after the heating element 2 is energized, the electric heating wire inside it generates heat) increases the temperature of the ink flowing through the heating channel, and then flows back to the pipeline of the ink supply system. In this way, the ink can be heated, so that the ink can maintain good activity, thereby better ensuring the quality of inkjet printing.

[0055] In actual use, one end of the heating channel inputs ink into the heating channel, while the other end of the heating channel outputs ink, and both the input and output are externally connected with corresponding pipelines. At the same time, when the inkjet printer is in use, the compressed clean air is blown into one end of the blowing channel 4 through the blowing pipe, and then blown out from the other end of the blowing channel 4. The clean air after blowing out is located in a relatively internal position of the equipment, so that the high pressure state can be maintained continuously in the inkjet printer, so that the inkjet printer blows out air, which can better prevent external impurities, dust, floating catkins, etc. from entering the interior of the inkjet printer, ensuring the cleanliness and use effect of the inkjet printer.

[0056] When producing the corresponding blowing channel 4, firstly, a T-shaped blowing groove 5 is pre-opened in the heating shell 1 (for example, the blowing channel 4 can be directly injection-molded during injection molding, and the openings at both ends of the blowing channel 4 are also injection-molded, which is simple and convenient to produce), and then the matching blowing fitting 6 is sealed and connected to the blowing groove 5, wherein the blowing fitting 6 only matches the shape of the outer side of the blowing groove 5, so that the blowing channel 4 is formed in the heating shell 1. Similarly, the production method of the first channel 7 and the second channel 8 is the same, which can also make the production easier and the cost lower.

[0057] The heating element 2 is engaged in the receiving groove 3, which can improve the strength and stability of the entire ink heating structure, and can also reduce the heat loss on the heating element 2, which is more energy-efficient. In actual use, the degree of ink heating varies in different seasons or temperatures, and different inks have different temperature requirements. At this time, it can be selected whether the ink is heated through the first channel 7 or the second channel 8 according to the actual situation.

[0058] The first channel 7 is linear or nearly linear and is located at the edge of the heating element 2, while the second channel 8 is serpentine or S-shaped and is directly opposite to the middle of the heating element 2. In this way, if the fluid requires a lower degree of heating, it will flow into the first channel 7, but if the fluid requires a higher degree of heating, the fluid will flow into the second channel 8; but if the fluid requires a medium degree of heating, the ink can be passed into the first channel 7 and the second channel 8 at the same time.

[0059] When the ink is actually introduced, the input source of the ink is the input main pipe 16 , and the ink is finally output to the outside through the third port 11 . If the first channel 7 is used to heat the ink at this time, the first adjustment channel 20 is opposite to the first input tube 9, and the second adjustment channel 21 and the third adjustment channel 22 are opposite to the inner wall of the adjustment housing 17, so that the ink can be heated through the first channel 7; if the second channel 8 needs to be used to heat the ink at this time, first, the rotating sleeve 27 is pulled outward through the operating disk 31 and the operating handle 30, so that the vertical arm 29 is separated from the corresponding positioning protrusion 28, and then the position of the operating disk 31 is maintained and the operating disk 31 is rotated. At this time, the rotating sleeve 27 drives the linkage column 24, the linkage part 23 and the adjustment column 18 to rotate (the adjustment housing 17 has an external bracket to keep its angle unchanged), and the vertical arm 29 is opposite to the second group of positioning protrusions 28, and then the operating disk 31 is released, so that the vertical arm 29 is clamped between the second group of positioning protrusions 28, and the angle of the adjustment column 18 can be ensured to be stable; similarly, if the first channel 7 and the second channel 8 need to be used to heat the ink at the same time, the vertical arm 29 is adjusted to be clamped between the third group of positioning protrusions 28, which is simple and convenient.

[0060] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
