As shown in FIG. 2, the air intake device 2 includes an air inlet 21 and an air inlet passage 22 communicating with the air inlet 21. When the integrated stove is in operation, soot enters from the air inlet 21, and the vehicle enters. The air passage 22 enters the air intake and exhaust device 3.

As shown in FIG. 3, the air intake and exhaust device 3 includes a fan chamber 31 having an air inlet 311 and an air outlet 312, a neck ring 32 disposed at the air inlet 311, and a fan ring 31 disposed in the fan chamber 31. a fan 33, wherein the air inlet is in communication with the air inlet, the fan 33 has two fan ports, and the two fan ports corresponding to the neck ring 32 are a first fan port 331, and the exhaust The port 312 is in communication with the second fan port 332. When the integrated stove is in operation, the soot is divided into two parts, a part of which flows out from the first fan port 331, and then flows along the outer wall of the neck ring 32, and a negative pressure is generated at the lower port of the neck ring 32, thereby increasing the neck ring. The soot flow rate in 32; the other portion flows out of the second blower port 332, passes through the exhaust port 312, and enters the air outlet device 4. Thus, the soot in the neck ring 32 is not only subjected to suction force, but also receives the force of the soot flowing out from the first fan port 331, and the flow rate of the soot in this case is greater than the flow rate under the suction force alone, that is, Driven by a motor of the same power, the flow rate of the soot increases, so the efficiency of the suction and exhaust is also significantly improved. It should be noted that the suction and exhaust device 3 may be closed except for the suction port 311 and the exhaust port 312 to prevent the soot from diffusing in the casing 1; in order to save production cost, the row The gas port 312 and the second fan port 332 may be integrated.

As shown in FIG. 4, the fan 33 includes a motor 333, two volutes 334, two smoke grooves 335 and two wind wheels 336, wherein the two smoke grooves 335 respectively correspond to the first fan port 331 and the second The fan port 332 is opposite to each other in the air inlet direction. The motor 333 is a double-shaft synchronous core motor and is interposed between the two volutes 334. The two wind wheels 336 are respectively disposed on the double output shaft of the motor 333. At both ends, the motor 333 is sandwiched between the two volutes 334 such that the two smoke grooves 335 form two spaces that are independent of each other.

As an alternative embodiment, the two volutes may be formed by combining one volute, that is, a partition plate is arranged in the middle of the volute to divide the volute into two separate smoke grooves, and the motor is fixed on the insulation plate.

It should be noted that the air intake and exhaust device 3 may also be in the form of a dual motor, that is, the fan 33 is composed of two independent small fans, each of which has a fan port, respectively, the first fan Port 331 and the second fan P 332.

The air intake and exhaust device 3 further includes a guide tube 34 located at the periphery of the neck ring 32. The lower portion of the air guide tube 34 is closed with the first fan port 331, so that when the integrated stove is in operation, the soot is from the first A blower port 331 flows out, first flows upward along the guide tube 34, and then flows down the neck ring 32. Since the gap between the guide tube 34 and the neck ring 32 is narrow, the flow rate of the soot will Significantly, the negative pressure generated at the lower port of the neck ring 32 is also significantly increased, thereby further increasing the soot flow rate in the neck ring 32. It is to be noted that, in order to reduce the resistance caused by changing the flow direction of the soot, the upper end of the neck ring 32, whether the inner wall or the outer wall, may have a curved design, and in the case where the guide tube 34 is provided, The longitudinal length of the neck ring 32 can be appropriately reduced.
