[0111] This utility model provides a drying unit.

[0112] The following is combined Figure 1-9 The drying unit of this utility model is described in an embodiment.

[0113] The drying unit of this utility model embodiment includes a first housing 1, a second housing 2, and a third housing 3.

[0114] The first housing 1 has a hot air channel 101; the second housing 2 has an air guide channel 201 and an air guide inlet 202 and an air guide outlet 203 connected to the air guide channel 201. The second housing 2 is connected to the first housing 1 through a first adjusting component 4 so that the air guide channel 201 is connected to the hot air channel 101 through the air guide inlet 202, and the second housing 2 is movable relative to the first housing 1 in its height direction; the third housing 3 is disposed in the air guide channel 201, the third housing 3 has an infrared generating cavity 301, an infrared heating element 302 is disposed in the infrared generating cavity 301, and the third housing 3 also has an infrared emission outlet 303 facing the outside of the second housing 2; the infrared heating element 302 is connected to the second housing 2 through a second adjusting component 5 so that the infrared heating element 302 is movable relative to the second housing 2 in its height direction.

At this time, the first adjusting component 4 does not lock or fix the first housing 1 and the second housing 2, and the second housing 2 can be moved to adjust its position, thereby adjusting the position of the second housing 2 relative to the first housing 1. After the adjustment is completed, the first adjusting component 4 can be switched to the first state.

[0140] Furthermore, the first adjustment hole 7 is an oblong hole and extends along the height direction of the second housing 2, which facilitates the adjustment of the position of the first adjustment rod 401 in the height direction of the second housing 2, thereby enabling the adjustment of the position of the second housing 2 relative to the first housing 1.
