[0039] The present utility model provides an electric oil radiator.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 In an embodiment of the present utility model, the electric oil radiator 10 includes an oil radiator main body 100, a housing 200, and a winding member 300. The housing 200 is disposed on the oil radiator main body 100; the winding member 300 is movably disposed on the housing 200, and the winding member 300 is moved to switch between a first state and a second state; in the first state, the winding member 300 is received on the housing 200 and is in a first position (as shown in Figure 5 and Figure 6 ); in the second state, the winding member 300 moves from the first position in a direction away from the oil radiator main body 100 to a second position, and a winding space 301 for winding and fixing a wire body is formed between the winding member 300 and the outer surface of the housing 200 (as shown in Figure 1 and Figure 2 ).

[0041] It can be understood that the housing 200 may have a receiving cavity, and the oil radiator main body 100 is disposed in the receiving cavity of the housing 200; or, the housing 200 is disposed at one end of the oil radiator main body 100, and at least part of the oil radiator main body 100 is disposed outside the housing 200. The winding member 300 is movably disposed on the housing 200, and the moving manner of the winding member 300 is not limited. For example, the winding member 300 switches between the first state and the second state by rotation; or, the winding member 300 switches between the first state and the second state by sliding.

[0042] When the winding member 300 is in the first state, the winding member 300 is received on the housing 200 and is in the first position. At this time, the winding member 300 can be completely received on the housing 200. Of course, it may also be that due to process problems and part processing errors, there is a gap between the winding member 300 and the housing 200, and the width of the gap is smaller than the width of the wire. When the winding member 300 is in the first state, it is received on the housing 200 without occupying the external space of the housing 200, which is beneficial to the miniaturization of the electric oil radiator 10. When the winding member 300 is in the second state, at least part of the winding member 300 extends outside the housing 200, and a winding space 301 is formed between the winding member 300 and the outer surface of the housing 200. The winding space 301 is used for winding and fixing a wire body, and the wire body can be a power cord or a wire for other purposes. For the convenience of wire winding, the winding space 301 is annularly arranged around the winding member 300, so as to facilitate wire winding.

[0043] The electric oil radiator 10 of the present utility model includes an oil radiator main body 100, a housing 200, and a winding member 300. The housing 200 is provided on the oil radiator main body 100, and the winding member 300 is movably provided on the housing 200. The winding member 300 is switched between a first state and a second state by moving. In the first state, the winding member 300 is received on the housing 200 and is in a first position. In the second state, the winding member 300 moves from the first position in a direction away from the oil radiator main body 100 to a second position, and a winding space 301 for winding and fixing a wire body is formed between the winding member 300 and the outer surface of the housing 200. With such a setting, when it is necessary to wind the wire body, the winding member 300 is moved so that the winding member 300 is in the second position. At this time, the winding space 301 is formed between the winding member 300 and the outer surface of the housing 200, and the wire body can be wound and fixed in the winding space 301 to realize the storage of the wire body. When it is not necessary to store the wire body, the winding member 300 is moved to the first position. At this time, the winding member 300 is received on the housing 200, and the winding member 300 does not occupy the space outside the housing 200. This is beneficial to the miniaturization of the electric oil radiator 10, and the structure of the electric oil radiator 10 is stable, and the winding member 300 will not collide with external objects. It can be seen that the present utility model provides an electric oil radiator 10 that is convenient for storing the wire body and beneficial to the miniaturization of the device.

[0044] In an embodiment, an installation hole is provided on the outer surface of the housing 200, and the winding member 300 is movably provided in the installation hole to be switched between the first state and the second state. It can be understood that by providing the installation hole, when it is not necessary to store the wire body, the winding member 300 can be completely received in the installation hole. At this time, the winding member 300 does not occupy the external space of the housing. When it is necessary to store the wire body, it is also convenient for the winding member 300 to move out of the installation hole. In addition, the shape and depth of the installation hole are not limited, and it is only necessary that the winding member 300 can switch states in the installation hole.

[0045] In one embodiment, the winding member 300 is slidably disposed in the mounting hole so that the winding member 300 can be switched between the first state and the second state by sliding. It can be understood that the winding member 300 changes its state by sliding, and the way of changing the state of the winding member 300 is simple, which is beneficial to simplifying the structure of the electric oil radiator 10. The mounting hole can be arranged to extend along the length direction of the oil radiator body 100. When the wire needs to be wound, the winding member 300 is pulled out from the mounting hole so that the winding member 300 is in the second position. At this time, a winding space 301 is formed between the winding member 300 and the housing 200, and the wire can be wound and fixed in the winding space 301 to realize the storage of the wire. When the wire does not need to be stored, the winding member 300 is pushed back to the storage position of the mounting hole, that is, the winding member 300 is in the first position. At this time, the winding member 300 does not occupy the space outside the housing 200, which is beneficial to the miniaturization of the electric oil radiator 10, and the structure of the electric oil radiator 10 is stable, and the winding member 300 will not collide with external objects.

[0046] Please refer to Figure 3 、 Figure 4 and Figure 7 In one embodiment, the winding member 300 includes a hook portion 330. The hook portion 330 is disposed in the mounting hole, and a limiting portion is provided in the mounting hole. In the second state, the hook portion 330 abuts against the limiting portion to prevent the winding member 300 from detaching from the housing 200.

[0047] It can be understood that the hook portion 330 can protrude from the outer peripheral wall of the winding member 300. The limiting portion can be the end wall of the mounting hole, or the limiting portion can be a limiting block protruding in the mounting hole. Specifically, it is not limited here, and it is only necessary that the limiting portion can block the hook portion 330 to prevent the winding member 300 from being pulled out of the mounting hole. By providing the hook portion 330 on the winding member 300 in this solution, it can prevent the user from accidentally separating the winding member 300 from the housing 200, ensuring the stability of the winding member 300 when switching states for use.

[0048] In one embodiment, a guiding surface 331 is provided on the outer wall of the hook portion 330 near one end of the oil radiator body 100. The guiding surface 331 is inclined toward the inside of the mounting hole from the direction of the housing 200 toward the oil radiator body 100. With such a setting, when assembling the winding member 300, the guiding surface 331 can guide the winding member 300 so that the winding member 300 can be smoothly inserted into the mounting hole, improving the smoothness of the assembly of the winding member 300. The guiding surface 331 can be an inclined surface arranged as a plane, or can be an inclined surface arranged as an arc surface. Specifically, it is not limited here.

[0049] Please refer to Figure 4 and Figure 7, in one embodiment, the winding member 300 further includes a winding portion 310 and a wire blocking portion 320. The hook portion 330 and the wire blocking portion 320 are provided at opposite ends of the winding portion 310. At least a part of the wire blocking portion 320 is disposed outside the mounting hole. In the second state, a winding space 301 is formed in the region between the wire blocking portion 320, the winding portion 310, and the housing 200.

[0050] It can be understood that the winding portion 310 is for winding the wire body, and the wire blocking portion and the housing 200 are for limiting the wire body. The wire blocking portion 320 can be entirely disposed outside the housing 200; or, a part of the wire blocking portion 320 is disposed inside the housing 200, and another part of the wire blocking portion 320 is disposed outside the housing 200. It is only necessary that when the winding member 300 is in the second state, the region between the wire blocking portion 320 disposed outside the housing 200, the winding portion 310, and the outer surface of the housing 200 can form the winding space 301.

[0051] Please refer to Figure 2 、 Figure 4 and Figure 7 , in one embodiment, a handle groove 302 is provided on the winding member 300, and the opening direction of the handle groove 302 faces away from the oil radiator main body 100. It can be understood that the handle groove 302 is for the user's fingers to extend into, so as to facilitate the user to hold the winding member 300 to move and carry the electric oil radiator 10; and, the opening direction of the handle groove 302 faces away from the oil radiator main body 100, and the oil radiator main body 100 will not interfere with the user's fingers and affect the extension of the fingers, which is convenient for the user to operate. In addition, the opening size and shape of the handle groove 302 are not limited, and it is only necessary to facilitate the user to extend and carry; the opening direction of the handle groove 302 can be directly opposite to the oil radiator main body 100. Of course, the opening direction of the handle groove 302 can also be inclined in the direction directly opposite to the oil radiator main body 100, which is not specifically limited here. Thus, when the electric oil radiator 10 needs to be moved, the user can hold the winding member 300 with the hand and extend the fingers into the handle groove 302, so as to facilitate the movement of the electric oil radiator 10. The winding member 300 of the present application integrates the handle function and the wire winding function, making the electric oil radiator 10 convenient to move and the wire body easy to store, and the electric oil radiator 10 has high applicability.

[0052] In one embodiment, at least a part of the handle groove 302 is provided on the wire blocking portion 320. It can be understood that the handle groove 302 can be entirely disposed on the wire blocking portion 320; or, a part of the handle groove 302 is disposed on the wire blocking portion 320, and another part of the handle groove 302 is disposed on the winding portion 310, that is, the handle groove 302 is recessed from the wire blocking portion 320 to the winding portion 310 to increase the depth of the handle groove 302, so as to facilitate the user to extend and hold the winding member 300.

[0053] In one embodiment, the wire blocking portion 320 extends along the width direction of the oil radiator main body 100, that is, the length direction of the wire blocking portion 320 is the same as the left - right direction. In this way, the space in the width direction of the oil radiator main body 100 is fully utilized, which is beneficial to the miniaturization of the electric oil radiator 10. Specifically, in this solution, the wire blocking portion 320 extends along the horizontal direction.

[0054] In one embodiment, the wire blocking portion 320 and the wire winding portion 310 are integrally formed, and the finger - holding groove 302 is provided on the wire blocking portion 320 and the wire winding portion 310.

Moreover, the bottom of the finger - holding groove 302 can be provided on the wire winding portion 310, and the opening of the finger - holding groove 302 is provided on the wire blocking portion 320, so that the depth of the finger - holding groove 302 is relatively deep, and the finger - holding groove 302 can make full use of the structures of the wire blocking portion 320 and the wire winding portion 310 to improve the space utilization rate.

[0055] In one embodiment, the opening width of the finger - holding groove 302 on the wire blocking portion 320 is greater than the opening width of the finger - holding groove 302 on the wire winding portion 310. It can be understood that the wire blocking portion 320 is provided at one end of the wire winding portion 310 away from the oil radiator main body 100. The opening width of the finger - holding groove 302 on the wire blocking portion 320 is greater than the opening width of the finger - holding groove 302 on the wire winding portion 310, so that the opening width of the finger - holding groove 302 near the opening is relatively large, facilitating the user's finger to extend in. In this way, the smoothness of the user's finger extending in is improved.

[0056] In one embodiment, the finger - holding groove 302 is arranged in a flared shape, which improves the smoothness of the user's finger extending in and facilitates the user to hold the winding member 300.

[0057] In one embodiment, the winding member 300 is arranged on the side of the housing 200 facing away from the oil radiator main body 100 and is located in the upper half of the housing 200. With this arrangement, the position of the winding member 300 on the housing 200 is relatively high, and the position where the user winds the wire is relatively high. Moreover, the winding member 300 is provided with a finger - holding groove 302, and the position where the finger extends into the finger - holding groove 302 when moving the electric oil radiator 10 is relatively high. The user does not need to squat or bend down to a lower position to operate, which improves the comfort of the user's operation.
