[0030] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0031] Figures 1 to 6 FIG. 1 shows a connection assembly according to an embodiment of the present invention, which is used to movably connect the burner 1 of a stove to the bottom shell 2 of the stove. Figure 1 and Figure 2 As shown, the connection assembly according to this embodiment may include a driving part 3 and a telescopic part 4. The driving part 3 is connected to the bottom shell 2, one end of the telescopic part 4 is connected to the output end of the driving part 3, and the other end of the telescopic part 4 is connected to the burner 1. The telescopic part 4 is driven to extend and retract by the power of the driving part 3, thereby driving the burner 1 to perform linear motion in the cavity formed by the bottom shell 2, thereby setting the burner 1 at the first position and the second position. It can be understood that, as Figure 5 and Figure 6 As shown, the burner 1 can have a smaller or larger thermal efficiency. When set in the first position or the second position, it can be used alone with a smaller thermal efficiency, or combined with another burner with different thermal efficiency to form a combined burner with a larger thermal efficiency.

[0032] According to an exemplary embodiment of the telescopic portion 4, Figure 3 As shown, the telescopic part 4 includes a lead screw 41, a connecting block 42 and a connecting rod 43. One end of the lead screw 41 ( Figure 3The left end of the lead screw 41 shown in the figure is connected to the output end of the driving unit 3. The lead screw 41 is threadedly connected to the connecting block 42 when passing through the connecting block 42. The connecting block 42 is driven to move along the axial direction of the lead screw 41 by rotating the lead screw 41 and keeping it stationary in the axial direction. One end of the connecting rod 43 ( Figure 3 The left end of the connecting rod 43 shown in the figure is fixed to the connecting block 42, and the other end of the connecting rod 43 is connected to the burner 1, so that the axial directions of the connecting rod 43 and the lead screw 41 can be coaxial or parallel, and the movement of the connecting block 42 drives the connecting rod 43 to move left and right, so that the burner 1 can be set in the first position on the left and the second position on the right. It can be understood that when the connecting block 42 is located at the left end of the lead screw 41, the burner 1 is set in the first position, and when the connecting block 42 is located at the right end of the lead screw 41, the burner 1 is set in the second position. Specifically, the connecting block 42 is as shown in FIG. Figure 3 In the structure shown, the left end has a larger diameter and the right end has a smaller diameter, the right end of the connecting block 42 is provided with an external thread, and the left end of the connecting rod 43 is provided with an internal thread, so that the connecting rod 43 and the connecting block 42 are fixed by threaded connection.

[0033] Further, the telescopic portion 4 may also include a housing 44, a support block 45 and a sealing member 48, and further reference is made to Figure 3 The housing 44 is arranged around the outer periphery of the lead screw 41, and the inner peripheral wall of the housing 44 abuts against the outer peripheral surface of the left part of the connecting block 42, which can ensure that dust or impurities fall into the connection between the lead screw 41 and the connecting block 42 and affect the smooth relative movement of the two. The seal 48 is connected to the housing 44 by bolts arranged along its axial direction, and the inner annular surface of the seal 48 abuts against the outer peripheral surface of the connecting rod 43, and the left end of the connecting rod 43 is supported on the housing 44 through the seal 48. The left end of the lead screw 41 is supported on the left end of the housing 44 through the support block 45. The bottom of the housing 44 is provided with two fixed feet 441 symmetrically arranged in a direction perpendicular to the axial direction of the housing 44, and each fixed foot 441 extends along the axial direction of the housing 44, so that the telescopic part 4 can be fixed and supported on the bottom shell 2 by the two fixed feet 441.

[0034] In order to prevent the support block 45 from sliding in the housing 44, the telescopic portion 4 may further include two sides ( Figure 3 The first retaining spring 46 abuts against the left end face of the support block 45, and extends radially outward from the left end face to the inner side wall of the embedded shell 44. The second retaining spring 47 abuts against the right end face of the support block 45, and extends radially outward from the right end face to the inner side wall of the embedded shell 44.

[0035] According to an exemplary embodiment of the driving unit 3, Figure 3As shown, the driving part 3 may include a first motor 31 and a transmission assembly 32. The first motor 31 is fixed to the housing 44 directly by bolts or indirectly by being connected to the bracket by bolts. One end of the transmission assembly 32 is connected to the output shaft of the first motor 31, and the other end of the transmission assembly 32 is connected to the screw 41, so that the driving direction of the first motor 31 (i.e., the rotation direction of the output shaft of the first motor 31) can be converted into the rotation direction of the screw 41, so that the driving part 3 and the telescopic part 4 are arranged in the space enclosed by the narrower bottom shell 2.

The extension direction of the worm 321 is perpendicular to the extension direction of the lead screw 41. The output shaft of the first motor 31 is extended along the worm 321 and the worm wheel 322. Figure 3 The extending direction perpendicular to the paper plane is converted into the lead screw 41 along Figure 3 As shown, along the left-right extension direction, the driving part 3 and the telescopic part 4 can be conveniently arranged in the part of the bottom shell 2 where the burner 1 is not arranged.

[0037] In order to stably and effectively connect the worm wheel 322 and the lead screw 41, continue to refer to Figure 3 The inner periphery of the worm wheel 322 is provided with a pin groove (not shown) extending in the radial direction thereof, and one end of the lead screw 41 away from the connecting rod 43 ( Figure 3 The left end of the lead screw 41 shown in the figure is provided with a pin hole 411. By setting the pin shaft 5 in the pin groove and the pin hole 411, the worm wheel 322 and the lead screw 41 can be fixed in the circumferential direction of both. In addition, the outer peripheral wall of the lead screw 41 is formed with a shoulder for the worm wheel 322 to abut against, and the transmission assembly 32 can also include a third retaining spring 323, one side wall of the third retaining spring 323 abuts against the left side wall of the worm wheel 322, and the third retaining spring 323 extends inward from the worm wheel 322 to be embedded in the lead screw 41, thereby fixing the worm wheel 322 and the lead screw 41 in the axial direction of both. When the worm 321 drives the worm wheel 322 to rotate, the lead screw 41 and the worm wheel 322 can be kept rotating synchronously.

[0038] In order to prevent the connecting rod 43 from remaining stable after extending a certain length out of the housing 44, the connecting assembly may further include a guide portion 6, which is arranged on one side of the connecting rod 43 extending out of the housing 44 ( Figure 3 The guide portion 6 is connected to the right end of the connecting rod 43 and the burner 1 through a connecting piece, so that the extension and retraction of the connecting rod 43 by the guide portion 6 plays a guiding role and supports the burner 1. Specifically, as Figure 4As shown, the guide portion 6 includes a plurality of balls 61, a first slide rail 62, a second slide rail 63 and a ball bearing plate 64. The cross section of the first slide rail 62 is in a "concave" shape and the opening faces the side away from the bottom shell 2 ( Figure 4 The opening of the first slide rail 62 shown in the figure is toward the top of the bottom shell 2). The cross section of the second slide rail 63 is in a "concave" shape and is covered on the top of the first slide rail 62 with the opening facing downward, so that the side walls of the second slide rail 63 can be arranged corresponding to the side walls of the first slide rail 62 and have an overlapping portion (such as Figure 4 The side wall of the second slide rail 63 is arranged on the inner side of the side wall of the first slide rail 62, and the second slide rail 63 is directly connected to the burner 1 or indirectly connected to the burner 1 and the connecting rod 43 through a connecting member. The cross section of the ball bearing plate 64 is in a "concave" shape and the opening of the ball bearing plate 64 is arranged in the same direction as the first slide rail 62 (as shown in FIG. Figure 4 The opening of the ball bearing plate 64 shown is toward the top of the bottom shell 2), so that the side wall of the ball bearing plate 64 can be sandwiched between the first slide rail 62 and the second slide rail 63. The side wall of the ball bearing plate 64 is provided with a plurality of supporting holes 641 for accommodating the balls 61, so that the plurality of balls 61 are arranged and sandwiched between the first slide rail 62 and the second slide rail 63.
