[0035] like Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, the utility model provides a waterproof curling rod, including a curling rod body 10, one end of the curling rod body 10 is provided with a breathable head 11, a rear plug 12 is installed on the breathable head 11, the breathable head 11 is provided with a breathable hole 13, the rear plug 12 is provided with an exhaust hole 14, a waterproof cavity 15 is provided between the breathable head 11 and the rear plug 12, a deformable air sealing piece 16 is provided in the waterproof cavity 15, the air sealing piece 16 can be partially tilted toward the side where the rear plug 12 is located and is clamped between the rear plug 12 and the breathable head 11, the gas expanded in the curling rod body pushes the air sealing piece 16 to deform and tilt through the breathable hole 13, and enters the waterproof cavity 15 through the gap formed between the deformed and tilted air sealing piece 16 and the breathable head 11, and then is discharged from the curling rod body 10 through the exhaust hole 14 on the rear plug 12. When the curling rod body 10 of the utility model is powered on and heated, the gas inside the curling rod body 10 will expand, and the excess gas will lift the air sealing sheet 16 and be discharged through the gap between the air sealing sheet 16 and the vent head 11. When the heating stops, the gas inside the curling rod body 10 cools and contracts, forming a negative pressure, which firmly absorbs the air sealing sheet 16 and blocks the vent hole 13, thereby achieving a waterproof effect.

[0036] Furthermore, in the waterproof curling iron provided by the utility model, the air-sealing piece 16 is in surface contact with the vent head 11, and the air-sealing piece 16 is in point contact with the rear plug 12. The air-sealing piece 16 of the present embodiment is a circular air-sealing piece 16. In the present embodiment, an annular contact surface is provided between the edge of the air-sealing piece 16 and the vent head 11, so that the air-sealing piece 16 can close the air hole 13. The air-sealing piece 16 is in point contact with the rear plug 12, which is mainly used to position the air-sealing piece 16 and leave space for the air-sealing piece 16 to tilt up. The point contact of the utility model may also refer to a contact with a relatively small contact area (relative to the surface contact area between the air-sealing piece 16 and the vent head 11).

[0037] Furthermore, in the waterproof curling rod provided by the utility model, a sinking groove 17 is provided on the vent head 11, the vent hole 13 is located on the sinking groove 17, the air sealing sheet 16 covers the sinking groove 17, and an air guiding space is formed between the sinking groove 17 and the air sealing sheet 16. The air guiding space can be used to buffer the gas coming out of the curling rod body 10 through the vent hole 13, so that the overflowing gas can smoothly lift the air sealing sheet 16 and then be discharged from the gap.

[0038] Furthermore, the utility model provides a waterproof curling iron, and the air permeable head 11 is provided with a plurality of air holes 13. The air permeable hole 13 of the utility model can be provided with a large through hole, and preferably a plurality of air permeable holes 13 can be provided, which cooperates with the air guide space to play a role of slowing down the flow. Furthermore, the utility model provides a waterproof curling iron, and the air permeable hole 13 is arranged close to the edge direction of the air sealing sheet 16. The part of the air sealing sheet 16 close to the air permeable hole 13 will receive a greater pressure, and the air permeable hole 13 is arranged close to the edge direction of the air sealing sheet 16 to facilitate the edge of the air sealing sheet 16 to be lifted for deflation.

[0039] Furthermore, the waterproof curling iron provided by the utility model has a plurality of protrusions 18 disposed on the inner side of the rear plug 12, and the protrusions 18 press the air-sealing sheet 16 onto the breathable head 11. Furthermore, the waterproof curling iron provided by the utility model has at least three protrusions 18, and the three protrusions 18 are disposed as the three vertices of an acute triangle. Specifically, the three protrusions 18 disposed in this embodiment are pressed at the edge of the air-sealing sheet 16, and the line connecting the three protrusions 18 can form an isosceles acute triangle. In this embodiment, a total of four protrusions 18 are disposed, and a fourth protrusion 18 is disposed on the midline of the triangle at the acute angle of the formed triangle to facilitate stable positioning, and the air-sealing sheet 16 will be tilted from the position where the two waists of the isosceles triangle are located to exhaust air.

[0040] Furthermore, in the waterproof curling rod provided by the utility model, a plurality of limit blocks 19 are arranged on the air-permeable head 11 around the air-sealing sheet 16, and at least two adjacent limit blocks 19 are arranged at intervals. In this embodiment, the plurality of limit blocks 19 are arranged symmetrically, and the adjacent limit blocks 19 are arranged at intervals. Six limit blocks 19 are arranged to form an installation position of the air-sealing sheet 16, which can facilitate the installation and positioning of the air-sealing sheet 16 and leave enough intervals to facilitate the discharge of gas.

[0041] Furthermore, in the waterproof curling iron provided by the utility model, the total gas flow area of ​​the air holes 13 is greater than the total gas flow area of ​​the exhaust holes 14. In this embodiment, the air holes 13 are three elliptical holes, the exhaust hole 14 is a circular hole, the cross-sectional area of ​​the exhaust hole 14 is small, and the sum of the cross-sectional areas of the three air holes 13 is large, which is convenient for exhaust and helps to reduce the probability of external water entering the waterproof cavity 15.

[0042] Furthermore, in the waterproof curling iron provided by the present invention, the air sealing sheet 16 is a silicone / rubber air sealing sheet 16, which is conducive to sealing on the one hand, and has sufficient flexibility on the other hand, so as to facilitate deformation, curling and recovery.

[0043] To sum up, when the curling rod body of the utility model is in the state of being electrically heated, the gas inside the curling rod body will expand, and the excess gas will lift the air sealing piece and be discharged through the gap between the air sealing piece and the air permeable head; when the heating stops, the gas inside the curling rod body cools and contracts, forming a negative pressure, which firmly adsorbs the air sealing piece and blocks the air hole, thereby achieving a waterproof effect.

[0044] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
