[0002] At present, the air intake duct of most integrated stoves is directly connected to the bellows. However, this connection method has the problem that on the one hand, the air intake duct will absorb oil smoke, so when the air intake duct and the bellows are disassembled for maintenance, the oil smoke in the air intake duct will flow out and cause pollution to the bellows. On the other hand, the sealing between the air intake duct and the bellows will be reduced after long-term use, so it needs to be improved. Summary of the invention

[0003] The utility model aims at the defects of the prior art such as inconvenient maintenance and poor sealing performance, and provides a new adapter structure of an air inlet duct and a bellows.

Therefore, when the air duct pipe needs to be repaired, the residual oil smoke in the air duct pipe will flow into the conversion head body to avoid contamination of the bellows. On the other hand, the sealing installation ring facilitates the installation of the air duct pipe and can also improve the sealing between the air inlet duct and the bellows.

[0007] Preferably, in the above-described adapter structure between an air inlet duct and an air box, the snap-in groove comprises a first vertical edge, an arc edge and a second vertical edge, and the first vertical edge, the arc edge and the second vertical edge together form the snap-in groove.

[0008] The clamping groove formed by the first vertical edge, the arc edge and the second vertical edge is more convenient and has lower cost during production.

[0009] Preferably, in the above-mentioned adapter structure between the air inlet duct and the air box, the sealing mounting ring is also provided with a fixing portion, and the fixing portion includes a first fixing edge and a first supporting edge, and the first fixing edge and the first supporting edge are both inclinedly arranged on the first vertical edge.

[0010] The fixing portion is provided for air intake duct installation.

[0011] Preferably, in the above-mentioned adapter structure between the air inlet duct and the air box, the length of the first fixed side is shorter than the length of the first supporting side.

[0012] The first fixing side is shorter than the first supporting side so that the air inlet can be installed more smoothly.

[0013] Preferably, in the above-mentioned adapter structure between the air inlet duct and the bellows, the adapter assembly includes a guide plate, and the guide plate is arranged at the lower end of the conversion head body and fits with the inner surface of the conversion head body.

[0014] The guide plate can guide the wind entering the air intake duct so that the bellows can exhaust air better.

[0015] Preferably, in the above-mentioned adapter structure between an air inlet duct and a bellows, the adapter assembly further comprises a connecting plate, a clamping block is provided on the connecting plate, and the adapter assembly and the bellows are clamped together via the clamping block.

[0016] The provision of the clamp block facilitates installation or removal of the adapter assembly on the bellows. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figure 1-5 The present invention is further described in detail with the following specific embodiments, but they are not intended to limit the present invention:

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, an adapter structure of an air inlet duct and a bellows includes a bellows 1 and an air inlet duct 2, and also includes an adapter assembly 3 and a sealing mounting ring 4, wherein the adapter assembly 3 includes a conversion head body 31, the lower end of the conversion head body 31 is connected to the bellows 1, the upper end of the conversion head body 31 is provided with a clamping portion 311, the sealing mounting ring 4 is provided with a clamping groove 41, the sealing mounting ring 4 and the conversion head body 31 are clamped with the clamping portion 311 and the clamping groove 41, and the air inlet duct 2 is connected to the sealing mounting ring 4.

[0025] Specifically, the upper end of the conversion head body 31 is an inner flange structure, and when the sealing installation ring 4 is installed thereon, an inverted structure is formed thereon, thereby preventing the sealing installation ring 4 from falling off when the air inlet duct 2 is installed or disassembled.

[0026] To be more specific, the plug-in port of the air inlet duct 2 is designed to be higher at the rear and lower at the front and back, so that the air inlet duct 2 is gradually in contact with the sealing mounting ring 4 when inserted into the adapter assembly 3, thereby effectively reducing the friction resistance generated when the plug-in port of the air inlet duct 2 and the sealing mounting ring 4 are in contact at the same time, and flipping the sealing mounting ring 4, preventing the sealing mounting ring 4 from falling off during the assembly process.

[0027] Preferably, the engaging groove 41 includes a first vertical edge 411 , an arc edge 412 and a second vertical edge 413 , and the first vertical edge 411 , the arc edge 412 and the second vertical edge 413 together form the engaging groove 41 .

[0028] Preferably, the sealing mounting ring 4 is further provided with a fixing portion 42 , and the fixing portion 42 includes a first fixing edge 421 and a first supporting edge 422 , and the first fixing edge 421 and the first supporting edge 422 are both obliquely arranged on the first vertical edge 411 .

[0029] Preferably, the length of the first fixing edge 421 is shorter than the length of the first supporting edge 422 .

[0030] Preferably, the adapter assembly 3 includes a guide plate 32 , which is disposed at the lower end of the conversion head body 31 and fits with the inner surface of the conversion head body 31 .
