[0028] The present application will be further described below in conjunction with the drawings.

[0029] Example 1

[0030] The embodiment of the present application provides a handle structure, which comprises a recess 1 arranged on an oil pocket 51 of a tail piece 5 of an oil warmer, the recess 1 is provided with a force receiving member 11 on at least one side groove wall corresponding to the top of the oil warmer, the force receiving member 11 protrudes from the groove wall of the recess 1, and a gap 12 is formed between the force receiving member 11 and the groove bottom of the recess 1, which can be used for a person to put his hand in to hold the force receiving member 11.

[0031] Specifically, as shown in the drawings, Figure 1 the present embodiment mainly considers to design a handle structure to facilitate the carrying or moving of the oil warmer, and the difficulty mainly concentrates on the tail piece 5 of the oil warmer based on the current structure of the oil warmer. Further, the recess 1 for receiving force is designed on the oil pocket 51 (upper oil pocket 51) of the tail piece 5 of the oil warmer, and the force receiving member 11 is arranged on the upper groove wall of the recess 1, so that the hand of a person can be put into the recess 1 and hold the force receiving member 11 through the gap 12 between the force receiving member 11 and the groove bottom of the recess 1, thereby providing a stable force receiving point and force receiving structure, and further facilitating the carrying or moving of the oil warmer by the person. The force receiving member 11 can also be arranged on the groove wall of the recess 1 in other directions to facilitate force receiving in other directions.

[0032] Further, the force receiving member 11 is an arc-shaped structure extending along the circumference of the recess 1, and the central angle of the arc line where the force receiving member 11 is located corresponds to an acute angle.

[0033] Specifically, as shown in the drawings Figure 3 With Figure 5 As shown in the drawings, the force receiving member 11 is arc-shaped and the central angle of the arc corresponding to the force receiving member 11 is an acute angle, so that a large enough force receiving range is provided, and the operation of the force receiving member 11 by the hands of a person is facilitated, so that force is received in multiple directions.

[0034] Preferably, the protruding height of the force receiving member 11 relative to the recess 1 gradually decreases in the direction close to the two ends of the force receiving member 11, so that the two ends of the force receiving member 11 are smoothly transitioned with the groove wall of the recess 1. As shown in the drawings Figure 3 As shown in the drawings, the two ends of the force receiving member 11 are smoothly transitioned with the recess 1 to eliminate the edges and corners.

[0035] Embodiment 2

[0036] This embodiment is an improvement based on embodiment 1, and part of the same content is referred to embodiment 1, which will not be repeated here.

[0037] The embodiment of the present application provides a handle structure, which further comprises a lifting rod 2, two ends of the lifting rod 2 are respectively bent to form a first assembly end 21 and a second assembly end 22, the first assembly end 21 can be accommodated in an assembly groove 41 on the oil warmer front shell 4, and the second assembly end 22 is provided with an assembly unit 3 which can be assembled with the recess 1.

[0038] Specifically, as shown in the drawings Figure 1 As shown in the drawings, the two ends of the lifting rod 2 are connected with the front and rear of the oil warmer, on the one hand, it is convenient for a person to directly carry the oil warmer through the lifting rod 2; on the other hand, the oil warmer can be suspended as a whole by using the lifting rod 2, according to the specific use requirement, the oil warmer is suspended to improve the heating efficiency of the indoor space; on the other hand, some clothes and other articles can be hung by using the lifting rod 2, which is convenient for drying the corresponding articles by using the oil warmer. The specific assembly mode of the lifting rod 2 is that, referring to the drawings Figure 3 , first, the first assembly end 21 (bent 180°) of the lifting rod 2 is assembled into the assembly groove 41 on the oil warmer front shell 4, and then the second assembly end 22 is connected and matched with the recess 1 by using the assembly unit 3.

[0039] Further, the assembly unit 3 comprises a connecting piece 31, the outer peripheral surface of the connecting piece 31 is provided with a protruding and circumferentially extending clamping piece 311, and the connecting piece 31 can be accommodated in the recess 1 in the assembled state; in the assembled state, the end surface of the connecting piece 31 abuts against the groove bottom of the recess 1, the edge of the clamping piece 311 abuts against the groove wall of the recess 1, and the part of the clamping piece 311 corresponding to the force receiving member 11 abuts against the force receiving member 11.

[0040] Specifically, as shown in the drawings Figure 1 With Figure 4As shown, the connecting piece 31 can be embedded into the groove 1, at this time, in the depth direction of the groove 1, the end surface of the connecting piece 31 abuts against the groove bottom of the groove 1, the clamping piece 311 on the connecting piece 31 abuts against the outer side surface of the force receiving piece 11 and the edge of the clamping piece 311 simultaneously abuts against the groove wall of the groove 1. In this way, the connecting piece 31 is fixed relative to the groove 1 in the radial direction of the groove 1 and in the depth direction of the groove 1 (inward direction), the freedom degree of the connecting piece 31 in the depth direction of the groove 1 (outward direction) is limited by the abutment of the first assembly end 21 on the assembly groove 41, and then the connecting piece 31 can be kept in the assembled state in the groove 1.

[0041] Preferably, the clamping piece 311 includes a plurality of clamping portions discontinuously extending in the circumferential direction on the outer peripheral surface of the connecting piece 31, and the plurality of clamping portions are spaced apart from each other and uniformly distributed in the circumferential direction. As shown in the drawings Figure 2 As shown, on the basis of ensuring the assembly structure of the clamping piece 311 abutting against the force receiving piece 11, the clamping piece 311 is arranged in a split structure, which can reduce the structural design and the use of materials.

[0042] Further, based on the clamping piece 311 including a plurality of clamping portions discontinuously extending in the circumferential direction on the outer peripheral surface of the connecting piece 31, the assembly mode of the clamping piece 311 and the force receiving piece 11 can be further improved, so that the clamping piece 311 is directly assembled into the gap 12 between the force receiving piece 11 and the groove bottom of the groove 1, which can improve the reliability of the structure. Specifically, the width of the spacing space between the adjacent two clamping portions in the clamping piece 311 is greater than or equal to the width of the force receiving piece 11 (or a notch is provided on the force receiving piece 11 for the clamping portion to pass through), so that the clamping portion can be staggered with the force receiving piece 11 and then enter the gap 12, and then rotated by a certain angle in the circumferential direction, so that the clamping portion abuts against the inner side surface of the force receiving piece 11.

[0043] Further, the assembly unit 3 further includes a connecting pin 32, the connecting pin 32 is L-shaped, and the two ends of the connecting pin 32 are respectively threadedly connected with the second assembly end 22 and the connecting piece 31; the second assembly end 22 is a movable structure capable of rotating relative to the main body of the lifting rod 2, so as to be threadedly connected with the connecting pin 32 by rotating.

[0044] Specifically, as shown in the drawings Figure 1 、 Figure 2 and Figure 4As shown, the connecting pin 32 is used to connect the connecting piece 31 with the second assembly end 22, and is also convenient for assembling the assembly unit 3. During assembly, the connecting pin 32 is connected with the connecting piece 31 through screwing, then the connecting piece 31 is assembled into the recess 1, and finally the second assembly end 22 is connected with the connecting pin 32. When the second assembly end 22 is connected with the connecting pin 32, there may be certain interference because the first assembly end 21 has been assembled with the assembly groove 41 in advance, but the interference during assembly of the second assembly end 22 with the connecting pin 32 can be overcome by the elasticity of the pull rod 2 and the non-rigid assembly structure between the first assembly end 21 and the assembly groove 41.

[0045] The second assembly end 22 can rotate relative to the main body of the pull rod 2, so that the main body of the pull rod 2 can be stationary during assembly, facilitating operation.

[0046] Further, the inside of the oil bag 51 where the recess 1 is located has a flow limiting hole (not shown in the drawings), which is used to limit the flow of the heat conducting oil entering the oil bag 51 to control the temperature of the oil bag 51. The flow limiting hole reduces the flow of the heat conducting oil into and out of the internal space of the oil bag 51 and reduces the flowability, so as to avoid the oil bag 51 being too hot to scald the hands of personnel during handling.
