[0028] like Figure 1-4 As shown, the embodiment of the present invention provides a fluid heater for a nozzle, comprising a heating sleeve 2 sleeved on the outer wall of the nozzle body 1, the inner wall of the heating sleeve 2 and the outer wall of the nozzle body 1 fit together, a resistance wire 3 is fixedly installed inside the heating sleeve 2, a plurality of through grooves 1 4 are opened through the heating sleeve 2, a plurality of limit blocks 5 are fixedly installed on the heating sleeve 2, a movable sleeve 6 is provided on the outer wall of the heating sleeve 2, a plurality of through grooves 2 7 are opened through the movable sleeve 6, a plurality of limit grooves 8 are opened on the inner wall of the movable sleeve 6, the limit blocks 5 are arranged inside the limit grooves 8, and the heating sleeve 2 and the movable sleeve 6 are rotatably connected. Next, a connecting sleeve 10 is fixedly installed on the top of the heating sleeve 2, and four deformable plates 11 are fixedly installed inside the connecting sleeve 10. A plurality of protruding plates 9 are fixedly installed on the movable sleeve 6, and the protruding plates 9 are arranged between two adjacent through grooves 2 7. A plurality of through grooves 3 12 are opened on the connecting sleeve 10, and the through grooves 3 12 are arranged between two adjacent deformable plates 11. A plurality of limit blocks 5 are respectively arranged at the upper and lower ends of the through groove 1 4. The winding density of the resistance wire 3 shows an increasing trend from top to bottom. The sizes of the through groove 1 4 and the through groove 2 7 are matched, and the four deformable plates 11 are evenly arranged in the inner circumferential direction of the connecting sleeve 10.

[0029] When the nozzle body 1 is heated by the fluid, the heating sleeve 2 is installed upward from the bottom end of the nozzle body 1. When the cylindrical uniform part of the nozzle body 1 contacts the deformable sheet 11, due to the deformable ability of the deformable sheet 11, the outer wall of the nozzle body 1 squeezes the deformable sheet 11, causing the deformable sheet 11 to deform and contact the outer wall of the nozzle body 1. When it is installed to a suitable height, four deformable sheets 11 are set. The interior of the deformable sheet 11 is a metal spring sheet covered with a rubber material on the outside. The rubber material on the surface of the deformable sheet 11 has good deformation ability and can fit the outer wall of the nozzle body 1. In the process of restoring the deformation, the deformable sheet 11 exerts pressure on the outer wall of the nozzle body 1. A constant pressure is applied, so that the friction between the contact part of the deformable sheet 11 and the nozzle body 1 is larger, so that the heating sleeve 2 can be stably installed on the outer wall of the nozzle body 1 when it is not subjected to additional downward pulling force, and then the resistance wire 3 is connected to the power supply. At this time, the through groove 2 7 and the through groove 1 4 are staggered with each other, so that the outer walls of the heating sleeve 2 and the movable sleeve 6 are combined into a shell without hollowing out. The resistance wire 3 heats the nozzle body 1 to prevent the liquid inside the nozzle body 1 from solidifying. Since the output part at the bottom of the nozzle body 1 is exposed to the air, compared with the internal operating temperature of the nozzle body 1, the bottom of the nozzle body 1 is always in a relatively low temperature state, and the resistance wire 3 is arranged more densely from top to bottom, and the resistance wire 3 is The heating at the bottom of the nozzle body 1 near the ejection part is more sufficient, thereby further avoiding condensation of the liquid at the output port of the nozzle body 1. When the nozzle body 1 does not need to be heated, the staff touches the raised piece 9 with their fingers or with the help of a tool and rotates the movable sleeve 6 in the circumferential direction. The outer wall of the limit block 5 is covered with rubber material and is in close contact with the limit groove 8. A certain force needs to be applied to push the movable sleeve 6 to rotate on the outer wall of the heating sleeve 2. By setting the raised piece 9, a force point is provided for the rotation of the movable sleeve 6, and at the same time, the staff's fingers are prevented from touching the heating sleeve 2 or the movable sleeve 6, thereby avoiding burns to the staff. By setting the heating sleeve 2 and the movable sleeve 6, the movable sleeve 6 is rotated until the through groove 4 is aligned with the through groove 8. When the grooves 2 7 are interconnected, the resistance wire 3 dissipates heat into the air, achieving fast and efficient cooling without the need to disassemble the heating sleeve 2, avoiding damage or wear caused by frequent disassembly and installation, and increasing the life and performance stability of the entire heating device. In addition, when the heat accumulates the most at the first time after use, the inside of the heating sleeve 2 can be dissipated quickly and promptly. Four through grooves 3 12 are provided on the outer wall of the connecting sleeve 10. When the deformable sheet 11 is squeezed into shape by the nozzle body 1, the connecting sleeve 10 will be slightly deformed. The through grooves 3 12 cooperate with the deformation of the connecting sleeve 10, while reducing the weight of the connecting sleeve 10, which is conducive to fixing the heating sleeve 2 on the outside of the nozzle body 1.

[0030] The technical solution provided by the present invention is that when the nozzle body 1 is heated for fluid, the heating sleeve 2 is installed upward from the bottom end of the nozzle body 1. When the cylindrical uniform part of the nozzle body 1 contacts the deformable sheet 11, due to the deformable sheet 11 having the deformable ability, the outer wall of the nozzle body 1 squeezes the deformable sheet 11, causing the deformable sheet 11 to deform and contact the outer wall of the nozzle body 1. When installed to a suitable height, the deformable sheet 11 applies a certain pressure to the outer wall of the nozzle body 1 in the process of restoring the deformation. The heating sleeve 2 can be stably installed on the outer wall of the nozzle body 1 when it is not subjected to additional downward pulling force. Then, the resistance wire 3 is powered on. At this time, the through groove 2 7 is staggered with the through groove 1 4, so that the outer walls of the heating sleeve 2 and the movable sleeve 6 are combined into a shell without hollowing out. The resistance wire 3 heats the nozzle body 1 to prevent the liquid inside the nozzle body 1 from solidifying. When the nozzle body 1 does not need to be heated, the staff touches the raised piece 9 with their fingers or with the help of tools and rotates the movable sleeve 6 in the circumferential direction. The outer wall of the limit block 5 is covered with rubber material and is in close contact with the limit groove 8. A certain force needs to be applied to push the movable sleeve 6 to rotate on the outer wall of the heating sleeve 2. The movable sleeve 6 is rotated to a state where the through groove 1 4 and the through groove 2 7 are connected to each other. The resistance wire 3 dissipates heat into the air, and fast and efficient cooling is achieved without removing the heating sleeve 2.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
