[0022] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0023] like Figure 1 In the preferred embodiment shown, the soldering iron 10 includes a main body 1 and a soldering iron head 2, which is mounted on the front end of the main body 1. The soldering iron head 2 has a heating element (not shown) inside, which generates heat when energized, thereby performing soldering operations.

[0024] like Figures 2 to 5As shown, the main body 1 includes a housing 11 and a control board 12 installed inside the housing 11. The housing includes a front part 111 and a rear part 112. A temperature regulating ring 13 made of transparent material is provided between the front part 111 and the rear part 112. The temperature regulating ring 13 is rotatably connected between the front part 111 and the rear part 112. A temperature display 14 is provided inside the temperature regulating ring 13. The temperature display 14 is electrically connected to the control board 12.

[0025] Specifically, the front part 111 of the outer casing is close to the soldering iron head 2, and the front part 111 and the rear part 112 are arranged along the longitudinal direction of the soldering iron 10. A temperature control ring 13 connects the front part 111 and the rear part 112, and the three together constitute the complete outer casing 11. Since the temperature control ring 13 is made of transparent material, the user can see the components inside the outer casing 11 through the temperature control ring 13. A temperature display 14 is disposed within the temperature control ring 13 and is used to display the current temperature of the soldering iron 10. The temperature control ring 13 has a certain width, and the size of the temperature display 14 in the longitudinal direction of the soldering iron is approximately equal to or slightly smaller than the width of the temperature control ring 13. Therefore, the user can easily observe the temperature value displayed on the temperature display 14 through the temperature control ring 13.

[0026] Preferably, the temperature display 14 is a digital tube, which is electrically connected to the control board 12 to display the temperature of the soldering iron in real time.

[0027] The outer casing 11 houses a temperature regulating mechanism 15 for adjusting the temperature of the soldering iron 10. The temperature regulating mechanism 15 is an internal gear transmission mechanism, comprising an internal gear ring 151 and an external gear 152 that mesh with each other. The internal gear ring 151 is formed on the inner surface of the temperature regulating ring 13, and the external gear 152 is coaxially connected to a rotary switch 16 mounted on the control board 12. When the user rotates the temperature regulating ring 13, the internal gear ring 151 drives the external gear 152 to rotate, which in turn drives the rotary switch 16 to rotate, thereby adjusting the temperature of the soldering iron.

[0028] In this invention, adjusting the temperature via rotary switch 16 is a common technique in the field, and will not be described in detail here.

[0029] like Figure 4 As shown, the control board 12 is basically located in the middle of the housing 11, and the temperature display 14 and the external gear 152 are located on both sides of the control board 12, thereby making effective use of the internal space of the soldering iron.

[0030] The soldering iron 10 also includes a power switch 17, which is electrically connected to the control board 12. The power switch 17 and the temperature display 14 are located on the same side of the control board 12 and on the same longitudinal section of the soldering iron 10. This arrangement allows the user to conveniently operate the power switch 17 and easily observe the temperature of the temperature display 14 while holding the soldering iron, without the problem of the temperature display 14 being obstructed.

[0031] The temperature control ring 13 is located in front of the power switch 17, which is more in line with the user's operating sequence and makes it easier for the user to adjust the temperature.

[0032] like Figure 2 and Figure 3 As shown, the soldering iron 10 also includes an inner shell 18, which is located inside the outer shell 11. A temperature control ring 13 is fitted onto the inner shell 18. The inner shell 18 has a first hole 181 and a second hole 182, located on two opposite sides of the inner shell 18. The first hole 181 corresponds to the temperature display 14, causing the temperature display 14 to protrude from the first hole 181. The second hole 182 corresponds to the external gear 152, exposing a portion of the external gear 152. Preferably, the second hole 182 is an arc-shaped hole to facilitate engagement between the exposed external gear portion and the internal gear ring 151.

[0033] The inner shell 18 is also provided with a third hole 183, which is positioned corresponding to the power switch 17, so that the power switch 17 protrudes from the third hole 183 and from the hole 110 on the outer shell 11, thereby allowing the user to operate it.

[0034] Specifically, the inner shell 18 is composed of an upper shell 18a and a lower shell 18b, with a first hole 181 and a third hole 183 located on the upper shell 18a, and a second hole 182 located on the lower shell 18b.

[0035] Preferably, the soldering iron 10 also includes a battery 3, which is disposed at the rear of the control board 12 for supplying power to the soldering iron.

[0036] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
