Specifically, the inserting base 20 is a shell structure with an opening at one end, and has a base bottom wall and a base side wall surrounding the base bottom wall, and the two ends of the base side wall in the length direction of the inserting base 20 are respectively provided with a connecting lug. The inserting base 20 is limited in the supporting structure 141, and the connecting lug is fixedly connected with the supporting structure 141 of the rear vertical plate 14 through a fastener such as a screw.

The base diapire 121 is provided with the first plug connector mounting hole of intercommunication base installation cavity and external environment, and a plurality of first plug connector mounting holes set up along the length direction interval of base diapire 121. One end of each first plug connector 30 is correspondingly inserted into one first plug connector mounting hole, extends out of the rear vertical plate 14 and is formed by injection molding with the bottom wall 121 of the base; the other end of the first plug 30 extends out of the base mounting cavity and through the rear side wall 124 of the heating chamber 12 into the heating cavity 126.

Each second plug connector 45 is correspondingly inserted into one second plug connector connecting hole, one end of each second plug connector 45 extends out of one side of the connecting piece 43 to be connected with the first plug connector 30 in an inserting mode, and the other end of each second plug connector 45 extends out of the other side of the connecting piece 43 to be connected with the heating component 41. The heating assembly 41 comprises a plurality of heating tubes, wherein two ends of at least some of the heating tubes are respectively connected to a second connector 45, and the middle of the heating tubes are bent and extended according to the shape of the heating liner 12 to form a larger heating area. In one embodiment, the heat pipe and the second connector 45 are integrally formed, and in other embodiments, the heat pipe and the second connector 45 can be detachably connected.

Specifically, in one embodiment, the heat generating component 41 includes a first heat generating pipe 412, a second heat generating pipe 414, and a third heat generating pipe 416. The two ends of the first heating tube 412 are connected to form a substantially rectangular ring structure, and are electrically connected with the third heating tube 416 through the electric connector 43; the second heat generating pipe 414 surrounds the first heat generating pipe 412, and two end parts of the second heat generating pipe 414 extend in parallel at intervals to connect two second connectors 45 respectively; the third heat generating pipe 416 surrounds the second heat generating pipe 414, and both end portions of the third heat generating pipe 416 extend in parallel at intervals to connect the two second socket connectors 45, respectively.

In this way, the first connector 30 is at least partially located in the heating cavity 126, the heating element 41 is detachably mounted in the heating cavity 126 from the opening end of the heating cavity 126, and the first connector 30 and the end of the second connector 45 located in the heating cavity 126 are elastically connected. The elastic insertion means that when the first connector 30 and the second connector 45 are inserted into each other, one of the first connector 30 and the second connector 45 can be elastically deformed in a radial direction by the other. When the first and

second connectors

30 and 45 are separated from each other, the deformation of the first or

second connector

30 or 45, which has been elastically deformed, disappears and is restored to the initial state. Therefore, when the heat generating structure 40 is mounted on the heating housing 10, the first connector 30 and the second connector 45 can be stably connected. When the heat generating structure 40 needs to be detached, the first connector 30 can be easily detached from the second connector 45.

In some embodiments, the first connector 30 defines a plug hole, and one end of the second connector 45 is detachably inserted into the plug hole to connect with the first connector 30.

Specifically, in one embodiment, the second connector 45 is substantially cylindrical, as shown in FIG. 5. The first connector 30 includes a first guiding section 32, a first elastic connector section 34, a first connecting section 36 and a first electrical connecting section 38 connected in sequence.

In the axial direction of the insertion hole, the inner diameter of the first guiding section 32 gradually increases from the end connected with the first elastic insertion section 34 to the other end, so as to provide guidance for the first insertion connector 30 and reduce the insertion difficulty of the first insertion connector 30. In the axial direction of the insertion hole, the inner diameter of the first elastic insertion section 34 gradually decreases from the end connected with the first guide section 32 to the end connected with the first connection section 36, and then gradually increases, and the first elastic insertion section 34 is provided with a plurality of expansion holes 341 extending along the axial direction of the insertion hole at intervals along the circumferential direction of the insertion hole, and the expansion holes 341 communicate the insertion hole with the external environment. The first connecting section 36 is substantially cylindrical and is inserted into the bottom wall 121 of the base. The first electrical connection section 38 is a plate structure, and the first electrical connection section 38 extends out of the rear vertical plate 14 to be electrically connected with an external power supply device, so as to supply power to the first plug connector 30. It is to be understood that the shape of the first connector 30 is not limited thereto, and may be differently configured as desired.

The maximum inner diameter of the first resilient insertion end 34 is smaller than the outer diameter of the second insertion part 45 when the first and

second insertion parts

30 and 45 are separated from each other. So, when second plug connector 45 inserts and locates in first elasticity plug connector section 34, first elasticity plug connector section 34 outwards expands under the effect of second plug connector 45, exerts the reaction force in order to increase frictional force between the two to second plug connector 45 prevents that second plug connector 45 from getting loose in the course of the work of oven.

As shown in fig. 6, in another embodiment, the second connector 45 includes a second connection section 452, a second elastic insertion section 454 and a second guide section 456 which are connected in sequence in an insertion direction of the second connector 45.

The second connection section 452 is inserted into the connection member 43 to be connected with the heat generating component 41. The second elastic inserting section 454 is substantially olive-shaped, the outer diameter of the second elastic inserting section 454 gradually increases from the end connected with the second connecting section 452 to the end connected with the second guiding section 456 and then gradually decreases, a compression cavity is formed in the second elastic inserting section 454, a plurality of compression holes 4541 extending along the inserting direction are formed in the second elastic inserting section 454 along the circumferential direction, and the compression holes 4541 communicate the compression cavity with the external environment. The end of the second guide section 456 remote from the second plug 45 is hemispherical so that it can be smoothly inserted into the first plug 30.

The maximum outer diameter of the second resilient insertion section 454 is larger than the inner diameter of the first insertion section 30 when the first insertion section 30 and the second insertion section 45 are separated from each other. Thus, when the second connector 45 is inserted into the insertion hole of the first connector 30, the second elastic insertion section 454 contracts inward under the action of the first connector 30, and applies a reaction force to the first connector 30 to increase the friction force therebetween, thereby preventing the first connector 30 from being loosened.

It is understood that in other embodiments, the first connector 30 is provided with a plug hole, and the second connector 45 is inserted into the plug hole. The specific structure of the first connector 30 and the second connector 45 is described with reference to the above embodiments and will not be described herein.

In some embodiments, the heat-generating structure 40 further includes a detachable handle 50, the detachable handle 50 is disposed on a side of the connecting member 43 facing the heat-generating component 41, and the second connector 45 passes through the detachable handle 50 and is connected to the heat-generating component 41. In this way, the operator can grasp the detachable grip 50 to detach the heat generating structure 40 without grasping the heat generating component 41. Further, in an embodiment, the detachable grip 50 has a plurality of gripping grooves 52 formed at an end facing the second connector 45 and extending along a length direction of the detachable grip 50, and a bottom wall 121 of the gripping grooves 52 is wavy along the length direction, so as to facilitate gripping by a user.

As shown in fig. 1, 2 and 7, in some embodiments, the heating apparatus 100 further includes at least two fixing members 60 for fixing the heat generating component 41 in a vertical direction.

Specifically, the fixing member 60 includes a connecting arm 61 and two catching arms 63 extending from opposite sides of the connecting arm 61 in the same direction, and a catching gap 65 with a variable width is formed between the two catching arms 63. The two fixing members 60 are spaced along the spacing direction between the left side wall 122 and the right side wall 123 of the heating inner container 12, the connecting arm 61 is mounted on the top wall 125 by a fastener and is located in the heating cavity 126, and the retaining gap 65 extends along the inserting direction of the second plug connector 45. Thus, the heating element 41 can be held in the holding gap 65 and can slide along the holding gap 65 in the plugging direction of the second plug connector 45.

The process of installing the heat generating structure 40 in the heating apparatus 100 is as follows:

the detachable handle 50 is first held, and the heating element 41 is inserted into the heating chamber and moved upward (i.e., in the direction of the top wall 125) until it is clamped to the fixing member 60. And then the heat generating structure 40 is pushed towards the rear side wall 124 until the second plug connector 45 is inserted into the first plug connector 30, and the installation of the heat generating structure 40 is completed.

The process of disassembling the heat generating structure 40 of the heating apparatus 100 is as follows

First, the mounting/dismounting handle 50 is held, and the heating structure 40 is pulled out in a direction away from the rear wall 124, so that the second connector 45 is separated from the first connector 30. Then moves downward (i.e., in the direction of the bottom wall 121) until the heat generating component 41 is disengaged from the fixing member 60, and finally removes the heat generating structure 40 from the heating cavity 126, thereby completing the detachment of the heat generating structure 40.
