[0021] The following further describes the present utility model in conjunction with the accompanying drawings through embodiments.

[0022] Refer to Figures 1 to 5 , a portable heater, comprising two heating plates 1 and a rotating shaft assembly 2. The heating plate 1 includes a housing 11, an electric heating element 12, and a mounting plate 13. The housing 11 is provided with an opening 101. The electric heating element 12 is arranged inside the housing 11, and the heating side of the electric heating element 12 corresponds to the opening 101. The mounting plate 13 is mounted on the opening 101, and a plurality of through holes 102 penetrate through the mounting plate 13. Preferably, the electric heating element 12 is an electric heating wire. When the electric heating element 12 works, it generates heat for the user to keep warm.

[0023] The two heating plates 1 are rotatably connected through the rotating shaft assembly 2. The rotating shaft assembly 2 includes a handle rod 21 and two rotating rods 22. The two rotating rods 22 are respectively fixedly connected to the two end portions of the handle rod 21. A first connecting seat 107 and a second connecting seat 108 are symmetrically arranged on the side of the housing 11 close to the rotating shaft assembly 2. A rotating sleeve 103 is fixedly connected to the first connecting seat 107, and an avoidance groove 104 is formed on the second connecting seat 108. The space between the first connecting seat 107 and the second connecting seat 108 of the housing 11 is used to accommodate the handle rod 21.

[0024] The rotating sleeve 103 is sleeved and rotatably connected to the rotating rod 22, so that the rotating sleeve 103 of the housing 11 corresponds to the avoidance groove 104 of another housing 11. The rotating sleeve 103 is in interference fit with the corresponding avoidance groove 104. The two heating plates 1 can be respectively rotated to realize the opening and closing flipping action of the heater. A plug head 202 is installed at the end of the rotating rod 22. The plug head 202 is provided with a connecting rod 203. A connecting groove 201 is formed at the end of the rotating rod 22. The connecting rod 203 is threadedly connected to the connecting groove 201. The plug head 202 is in interference fit with the opposite side of the rotating sleeve 103 to prevent the rotating sleeve 103 from disengaging from the rotating rod 22.

[0025] A detent screw 105 is provided on the inner wall of the avoidance groove 104. A plurality of gear grooves 106 distributed in an annular array are formed on the outer wall of the rotating sleeve 103. The steel ball of the detent screw 105 is matched with its corresponding gear groove 106. A lever groove 111 is formed on the side wall of the housing 11 away from the mounting plate 13. When the heater is in use, the user can insert his hand into the lever groove 111 to drive the two heating plates 1 to perform a hinge flipping action around the rotating rod 22. The steel ball of the detent screw 105 is inserted into its corresponding gear groove 106 to position the two heating plates 1, so that the user can adjust the angle between the two heating plates 1 according to needs, and the use is relatively flexible. Preferably, a first magnetic member 109 and a second magnetic member 110 are respectively provided on the first connecting seat 107 and the second connecting seat 108. When the first connecting seat 107 of the housing 11 is matched with the second connecting seat 108 of another housing 11, the two heating plates 1 are unfolded into a plate shape, and the first magnetic member 109 and its corresponding second magnetic member 110 are adsorbed to each other to maintain the positions of the two heating plates 1. A movable groove 112 is formed on the side wall of the housing 11 away from the mounting plate 13. A leg member 113 is hinged in the movable groove 112, and the leg member 113 can be unfolded outward. The two heating plates 1 after unfolding can be supported by the two leg members 113, so as to place the heater on a table or the ground. When the heater is stored, the two heating plates 1 can be stacked to change the occupied space of the heater. The handle rod 21 is provided for the user to hold, which is convenient for carrying the heater.

[0026] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
