[0059] On the other hand, it can be used without an external power supply and has no restrictions on use. When you are out, such as hiking, outings, and picnics, in a place without power supply, it can still be used, making it highly adaptable.

[0060] Furthermore, the removable rechargeable battery 50 is fixedly mounted in the hollow cavity of the lower direct-heating plate assembly 20 and can be plugged in and out through the access port at the rear end of the lower direct-heating plate assembly 20, so that it can be easily removed and replaced. When it is out of power, it can be taken out and charged with an external AC power supply, and another removable rechargeable battery 50 with power can be replaced in the hollow cavity of the lower direct-heating plate assembly 20, so that the present application can be used uninterruptedly, and it can also be charged with an external AC power supply when it is not taken out, making the charging flexible.

[0061] At the same time, the present application is equipped with a detachable rechargeable battery 50, and the user can carry the present application to different countries and still use it independently, making the present application reliable and convenient to use.

[0062] Furthermore, the present application is highly practical and has good use effect.

[0063] Preferably, in this technical solution, specifically, refer to Figure 3 and Figure 4 As shown; the upper direct heating plate assembly 10 includes an upper shell 101 and an upper heating plate 102 installed at the bottom front part of the upper shell 101 along the length direction of the upper shell 101; the lower direct heating plate assembly 20 includes a lower shell 201, a lower heating plate 202 installed at the top front part of the lower shell 201 along the length direction of the lower shell 201, and a lower sub-shell 203 covering the upper rear part of the lower shell 201;

[0064] The lower heating plate 202 is positioned opposite to the upper heating plate 102; the lower heating plate 202 and the upper heating plate 102 are both electrically connected to the heating control component 40; the hollow cavity is formed between the lower sub-shell 203 and the middle and rear parts of the lower shell 201; the rear part of the lower sub-shell and the rear part of the lower shell form the taking port.

[0065] And preferably, in the present technical solution, the rotating shaft member 30 includes a left rotating shaft seat 301 and a right rotating shaft seat 302;

[0066] The left rear middle of the lower shell 201 is provided with a left fixing ear 2011 upward; the left end face of the left fixing ear 2011 is provided with a left-turning hole 2012 penetrating the middle of the right end face thereof; the right rear middle of the lower shell 201 is provided with a right fixing ear 2013 upward; the right end face of the right fixing ear 2013 is provided with a right-turning hole 2014 penetrating the middle of the left end face thereof;

[0067] Furthermore, the left-hand shaft seat 301 is fitted and fixed to the left end surface of the left fixing ear 2011, and a left shaft rod 3011 is inserted and fixed to the left-hand hole 2012 in the middle of its right end surface; the right-hand shaft seat 302 is fitted and fixed to the right end surface of the right fixing ear 2013, and a right shaft rod 3021 is inserted and fixed to the right-hand hole 2014 in the middle of its left end surface;

[0068] A left connecting ear 1011 is provided downwardly on the left side of the rear end of the upper shell 101 and is fixedly sleeved to the outside of the left shaft rod 3011; a right connecting ear 1012 is provided downwardly on the right side of the rear end of the upper shell 101 and is fixedly sleeved to the outside of the right shaft rod 3021;

[0069] A battery gap is formed between the left shaft 3011 and the right shaft 3021 ; when the detachable rechargeable battery 50 is fixed in the hollow cavity, the front end thereof passes through the battery gap.

[0070] Therefore, it can be foreseen that in the present application, a portion of the removable rechargeable battery 50 is located at the rear of the rotating shaft 30, and a portion is located at the front side of the rotating shaft 30, so that the overall length of the present application can be made shorter, so that the structure is compact, the overall length is short, and the space occupied is small.

[0071] Further, in the technical solution, the present application also includes a top spring 60 for propping apart the upper direct-emission heating plate assembly 10 and the lower direct-emission heating plate assembly 20 in a natural state;

[0072] Among them, an upper spring fixing position 1013 is provided on the inner top surface of the upper shell 101 near its rear end; a lower spring fixing position 2031 is provided on the upper top surface of the lower sub-shell 203 near its rear end; the top spring 60 is fixedly connected between the upper spring fixing position 1013 and the lower spring fixing position 2031.

[0073] Therefore, in the natural state, the present application uses the top spring 60 to open the upper straight heating plate assembly 10 and the lower straight heating plate assembly 20. Compared with the traditional torsion spring opening component, it has a simpler structure, lower cost, more convenient disassembly and assembly, and easier replacement, making it very convenient to use.

[0074] When the upper hair straightening heating plate assembly 10 is pressed downward, the upper heating plate 102 thereon can fit with the lower heating plate 202 of the lower hair straightening heating plate assembly 20 to clamp the user's hair to facilitate straightening the user's hair.

[0075] Furthermore, in the present technical solution, the heating control component 40 comprises a main control PCB board 401 horizontally mounted in the middle of the lower shell 201, a main controller 402 and a main power switch 403 arranged on the main control PCB board 401;

[0076] Among them, the upper heating plate 102 and the lower heating plate 202 are connected to the main controller 402 through a temperature control circuit 404 provided on the main control PCB board 401; the main power switch 403 is provided on the upper end surface of the main control PCB board 401 and is connected to the main controller 402.

[0077] Therefore, when the present application is not in use or is being transported, the present application can be turned off through the main power switch 403 to completely cut off the power to the upper direct-heating plate assembly 10 and the lower direct-heating plate assembly 20, making it safe and reliable when not in use and during transportation.

[0078] Preferably, in this embodiment, the lower front end of the lower sub-shell 203 extends forward and is horizontally provided with a sealing plate 2032 to seal and cover the main control PCB board 401, and the upper end surface of the sealing plate 2032 is provided with a linkage switch 2033 that abuts against the main power switch key 403. For details, refer again to Figure 3 and Figure 4 shown.

[0079] In this way, the main controller 402 and the main power switch 403 on the main control PCB board 401 have good waterproof sealing performance, making the use safer and more reliable.

[0080] Furthermore, in the present technical solution, the heating control component 40 of the present application further includes a sub-PCB board 405; the sub-PCB board 405 is vertically arranged in the middle of the lower shell 201 along the left-right direction, and is located at the rear side of the main control PCB board 401; the front end surface of the sub-PCB board 405 abuts against the front inner wall of the lower sub-shell 203, and the upper part of the rear end surface of the sub-PCB board 405 is provided with two limit plug-in columns 406 in parallel to the rear, and the lower part of the rear end surface of the sub-PCB board 405 is provided with a positive pole connecting pin 407 and a negative pole connecting pin 408 connected to the main controller 402 in parallel to the rear;

[0081] Based on this, Figure 3-Figure 6 As shown, the upper part of the front end surface of the removable rechargeable battery 50 is provided with two limit holes 501 suitable for the corresponding insertion of the two limit plug posts 406 in parallel and backward; the lower part of the front end surface of the removable rechargeable battery 50 is provided with a positive pole connection spring piece 502 suitable for the rear end of the positive pole connection ejector pin 407 to electrically abut against and a negative pole connection spring piece 503 suitable for the rear end of the negative pole connection ejector pin 408 to electrically abut against.

[0082] In this way, when the removable rechargeable battery 50 described in the present application is inserted into the hollow cavity through the taking port in a preset orientation, it can be electrically connected to the sub-PCB board 405 to supply power to the main controller 402. Specifically, it is mainly achieved by electrically abutting the rear end of the positive electrode connecting pin 407 provided on the rear end surface of the sub-PCB board 405 against the positive electrode connecting spring 502 provided on the front end surface of the removable rechargeable battery 50, and by electrically abutting the rear end of the negative electrode connecting pin 408 provided on the rear end surface of the sub-PCB board 405 against the negative electrode connecting spring 503 provided on the front end surface of the removable rechargeable battery 50, so as to achieve electrical conduction and supply.

[0083] Furthermore, when the removable rechargeable battery 50 described in the present application is inserted into the hollow cavity through the taking port in a preset orientation, the two limiting plug posts 406 provided on the rear end surface of the auxiliary PCB board 405 will be correspondingly inserted into the two limiting plug holes 501 provided on the upper part of the front end surface of the removable rechargeable battery 50, so that the inserted removable rechargeable battery 50 has a good anti-rotation effect and will not rotate in a circumferential direction, so that the rear end of the positive electrode connecting pin 407 provided on the rear end surface of the auxiliary PCB board 405 and the positive electrode connecting spring piece 502 provided on the front end surface of the removable rechargeable battery 50 are electrically abutted stably and reliably without disconnection, and the rear end of the negative electrode connecting pin 408 provided on the rear end surface of the auxiliary PCB board 405 and the negative electrode connecting spring piece 503 provided on the front end surface of the removable rechargeable battery 50 are also electrically abutted stably and reliably without disconnection, so that the power supply reliability of the removable rechargeable battery 50 described in the present application is good.

[0084] Furthermore, in the present technical solution, the rear portion of the lower shell 201 described in the present application forms a cylinder 2015; the rear portion of the cylinder is open to form the taking port; the inner wall of the cylinder 2015 is provided with a limit groove 2016 along the front-to-back direction; the outer wall of the removable rechargeable battery 50 is provided with an insertion limit block 504 suitable for being stuck in the limit groove 2016 for positioning the insertion direction.

[0085] In this way, the insertion limit block 504 is facing the limit groove 2016, and then the removable rechargeable battery 50 is inserted into the hollow cavity through the taking port. At this time, the insertion limit block 504 will be stuck in the limit groove 2016. In this way, the insertion direction of the removable rechargeable battery 50 described in the present application can be limited, so that it will not be inserted upside down or inserted off-center, making the use of the present application more reliable.

[0086] At the same time, in this embodiment, a slot 2017 is provided forwardly on the inner wall of the rear end of the cylinder 2015, and a locking slot 2018 is provided at the front end of the slot 2017 along the circumferential direction of the inner wall of the cylinder 2015;

[0087] Based on this, in the present embodiment, a locking sleeve 505 is rotatably provided on the outer wall of the rear end of the removable rechargeable battery 50; a locking plate 506 suitable for being inserted into the slot 2017 is provided forwardly at the front end of the locking sleeve 505, and a locking protrusion 507 suitable for sliding into the locking groove 2018 when the locking plate 506 is rotated is convexly provided on the outer surface of the locking plate 506; a limiting strip 2019 is provided in the locking groove 2018 near the slot 2017 to secure the locking protrusion 507.

[0088] Thus, the insertion limit block 504 is aligned with the limit groove 2016, and the locking plate 506 is aligned with the slot 2017, and then the removable rechargeable battery 50 is inserted into the hollow cavity through the access opening. When the removable rechargeable battery 50 is fully inserted into the hollow cavity, the locking plate 506 is simultaneously inserted into the slot 2017. After that, the locking sleeve 505 can be rotated to drive the locking plate 506 and the locking protrusion 507 thereon to rotate to the locking groove. 2018, the locking protrusion 507 can be limited and locked by the limiting strip 2019, so that it is not easy to slide out of the locking groove 2018, and the locking sleeve 505 is not easy to rotate after being rotated and fixed. Through the locking of the locking sleeve 505, the removable rechargeable battery 50 is not easy to slide out from the rear end access port of the hollow cavity after being fully inserted into the hollow cavity, so that the removable rechargeable battery 50 is firmly inserted and fixed, and the stability and reliability of the application are better.

[0089] On the contrary, the locking sleeve 505 is rotated in the reverse direction with force to make the locking protrusion 507 slide out of the locking groove 2018 to the insertion slot 2017, and then the removable rechargeable battery 50 is pulled back with force to be taken out from the hollow cavity.

[0090] Therefore, in combination with the above, it can be concluded that the removable rechargeable battery 50 described in the present application is easy to insert and remove during use, and is firmly inserted and placed in the hollow cavity and is not easy to fall off, making the present application truly reliable to use.

[0091] In the preferred embodiment, two locking plates 506 are arranged opposite to each other, each of which is provided with a locking protrusion 507. Correspondingly, two slots 2017 and two locking grooves 2018 connected thereto are also provided respectively, and a limiting strip 2019 is provided in each of the two locking grooves 2018, so that the locking sleeve 505 described in the present application can be fixed more firmly when being rotated and fixed.
