[0037] Referring to Figures 1 to 11 , a multifunctional hair styling device provided by the present utility model includes a handheld part 10, a connecting component 20, and a clamping plate mechanism 30. The handheld part 10 includes a battery 110. The handheld part 10 is detachably disposed on the connecting component 20 to facilitate battery replacement 110. The clamping plate mechanism 30 is detachably disposed on the connecting component 20. The clamping plate mechanism 30 includes a pair of clamping plate assemblies 310 that are oppositely arranged and can generate heat after being electrically connected to the battery 110. During use, power can be supplied through the battery 110 to make the clamping plate assemblies 310 generate heat. Here, the battery 110 can be a primary battery or a rechargeable battery. Both of the two clamping plate assemblies 310 are provided with arc-shaped parts, and the arc-shaped parts are provided with flat surfaces 40. The upper clamping plate assembly 310 is fixedly disposed on the connecting component 20, and the lower clamping plate assembly 310 is rotatably disposed on the connecting component 20. When using the two clamping plate assemblies 310 to clamp hair, the two flat surfaces 40 can be mutually attached. Before clamping the hair between the two clamping plate assemblies 310, first rotate the lower clamping plate assembly 310 in a certain direction to make the two flat surfaces 40 open at an acute angle. After the hair is placed, rotate the lower clamping plate assembly 310 in the reverse direction to make the two flat surfaces 40 mutually attached again.

[0038] In some alternative embodiments, such as Figure 10As shown, the splint assembly 310 includes a plate body 311 and a heating element (not shown in the drawings). The plate body 311 includes a straight wall plate 3111 and an arc-shaped arm plate 3112. The straight wall plate 3111 and the arc-shaped arm plate 3112 are connected around, so as to form a first accommodation cavity 3113 in the middle of the area surrounded by them. The heating element is installed in the first accommodation cavity 3113, and the flat surface 40 is arranged on the outer side of the straight wall plate 3111. When the heating element is connected to the battery 110, it will generate heat and conduct the heat to the straight wall plate 3111 and the arc-shaped arm plate 3112. When the temperature of the flat surface 40 on the straight wall plate 3111 and the outer surface of the arc-shaped arm plate 3112 reaches a certain value, high-temperature straightening and curling operations can be performed on the hair. Preferably, the heating element is a PCT heating body. The PCT heating body is called a PTC heater, which is composed of a PTC ceramic heating element and an aluminum tube. It has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater.

[0039] In some alternative embodiments, such as Figure 4 , Figure 5 , Figure 10 , Figure 11 As shown, the connecting assembly 20 includes a cylinder shell 21, a positioning seat 22, and a pressing seat 23.

[0041] In some alternative embodiments, such as Figure 10 , Figure 11As shown, a reset member 24 is provided between the positioning seat 22 and the pressing seat 23. Optionally, the reset member 24 can be a spring. When the pressing seat 23 is pressed, the lower clamping plate assembly 310 rotates downward from the initial position, and at the same time, the pressing seat 23 presses the spring upward. When the pressing of the pressing seat 23 stops, under the action of the spring, the lower clamping plate assembly 310 rotates upward until it returns to the initial position. It should be noted that the aforementioned initial position refers to the upper and lower clamping plate assemblies 310 being arranged side by side and their flat surfaces 40 being in contact with each other.

[0042] In some alternative embodiments, such as Figure 10 、 Figure 11 As shown, the left end of the upper plate body 311 is provided with an opening, and the positioning seat 22 is provided with a first positioning plug-in block 223 that matches the shape of the opening at the left end. When assembling the upper clamping plate assembly 310, first insert the first positioning plug-in block 223 into the opening at the left end of the upper plate body 311, and then fix the positioning seat 22 and the plate body 311 together through fasteners. Further, the opening area at the left end of the upper plate body 311 communicates with the first accommodation cavity 3113 in the upper plate body 311 to facilitate inserting the heating element into the first accommodation cavity 3113 from this opening.

[0043] In some alternative embodiments, such as Figure 10 、 Figure 11 As shown, the left end of the lower plate body 311 is provided with an opening, and the pressing seat 23 is provided with a second positioning plug-in block 232 that matches the shape of the opening at this end. When assembling the lower clamping plate assembly 310, first insert the second positioning plug-in block 232 into the opening at the left end of the lower plate body 311, and then fix the pressing seat 23 and the lower plate body 311 together through fasteners. Further, the opening area at the left end of the lower plate body 311 communicates with the first accommodation cavity 3113 in the lower plate body 311 to facilitate inserting the heating element into the first accommodation cavity 3113 from this opening.

[0044] In some alternative embodiments, such as Figure 10 、 Figure 11 As shown, the clamping plate assembly 310 further includes a cover 312, and the cover 312 is fixedly provided at one end of the plate body 311 away from the connecting assembly 20. Preferably, the right ends of the two plate bodies 311 are both provided with openings, and the cover 312 is inserted into the openings at the right ends of the plate bodies 311, so as to facilitate inserting the heating element into the first accommodation cavity 3113 from this opening. During specific installation, fasteners can also be used to lock the cover 312 and the plate body 311 together to prevent the cover 312 from falling off the plate body 311 during use.

[0045] In some alternative embodiments, such as Figure 1 、 Figure 2, Figure 10 , Figure 11 As shown in Figure 10 and Figure 11 , the splint assembly 310 further includes anti-scalding teeth 313, which are arranged in an array on the arc-shaped arm plate 3112. In this embodiment, on the one hand, by providing the anti-scalding teeth 313, it can prevent the high-temperature arc-shaped arm plate 3112 from scalding the user during the use of this multifunctional hair styling device; on the other hand, it can also play a role in combing the hair.

[0046] In some alternative embodiments, as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown in Figure 1 to Figure 9 , the handheld part 10 further includes a housing 120. A second accommodation cavity 121 is provided inside the housing 120. The battery 110 is limited and sleeved in the second accommodation cavity 121, and the front end portion of the battery 110 extends into the second accommodation cavity 121. Specifically, in order to enable only a part of the front end of the battery 110 to extend into the second accommodation cavity 121, a convex block 111 is provided on the outer surface of the battery 110, and correspondingly, a groove 122 is provided on the inner surface of the housing 120. Among them, a pair of convex blocks 111 and grooves 122 can be provided and symmetrically arranged. After the convex block 111 is inserted into the groove 122, the front end of the battery 110 cannot continue to extend into the second accommodation cavity 121. In addition, a positioning block 112 and a blocking block 113 are provided on the outer surface of the part where the front end of the battery 110 extends into the second accommodation cavity 121. A positioning groove 212 is provided on the barrel shell 21 that cooperates with the positioning block 112. It can be understood that a positioning groove 212 can also be provided on the outer surface of the part where the front end of the battery 110 extends into the second accommodation cavity 121, and correspondingly, a positioning block 112 that cooperates with the positioning groove 212 is provided on the barrel shell 21. When the positioning block 112 is inserted into the positioning groove 212, the battery 110 cannot rotate relative to the barrel shell 21. A through chute 213 is provided on the barrel shell 21, and a push block 2131 is slidably arranged in the chute 213. The bottom end of the push block 2131 abuts against the outer surface of the battery 110, that is, the bottom end of the push block 2131 is clamped between the outer surface of the battery 110 and the inner surface of the barrel shell 21. At the same time, the top end of the push block 2131 is located outside the chute 213. During specific design, the dimensions of the top end and the bottom end of the push block 2131 are both designed to be larger than the size of the chute 213, so that the push block 2131 will not fall off from the chute 213. The blocking block 113 corresponds to the position of the chute 213. Here, the correspondence means that one end of the battery extends along the Figure 8After being inserted into the barrel shell 21 in the direction of the one-way arrow shown, when the pushing block 2131 is shifted to the left side of the sliding groove 213, the blocking block 113 is resisted by the bottom end of the pushing block 2131. At this time, the battery 120 cannot be pulled out in the opposite direction of the one-way arrow. When the pushing block 2131 is shifted to the right side of the sliding groove 213, the blocking block 113 does not block the bottom end of the pushing block 2131. At this time, the battery 120 can be inserted into and pulled out of the barrel shell 21.

[0047] In summary, in the present application, by providing an arc portion on the clamping plate assembly 310, the hair can be wound around two oppositely arranged arc portions, and the effect of curling the hair can be achieved without rotating the entire shaper. Moreover, the hair can be wound multiple times to achieve the effect of curling a large area of hair. At the same time, one of the clamping plate assemblies 310 can be set to a rotating state, and flat surfaces that can fit together are provided on the two clamping plate assemblies 310. In this way, it is convenient to clamp the hair between the two flat surfaces, and the effect of straightening the hair can be achieved when the shaper is moved as a whole. In addition, since the clamping plate mechanism 30 is integrally fixed to the connecting component 20, the clamping plate mechanism 30 can also be disassembled and replaced with a blower, and the battery 110 in the handheld portion 10 is used to supply power to it, so that the wet hair can be dried, performing the function of a hair dryer.
