Further, as shown in fig. 3 and 4, the fresh air ejector 200 includes:
the outer barrel 210 is provided with an outer barrel air inlet 201 and an outer barrel air outlet 202, and an air passage 204 is formed between the outer barrel air inlet 201 and the outer barrel air outlet 202; the wall of the outer cylinder 210 is provided with an outer cylinder air guiding opening 203, and the outer cylinder air guiding opening 203 is communicated with the air passing channel 204 and a space outside the wall of the outer cylinder 210;
an inner cylinder 220, wherein the inner cylinder 220 is arranged in the air passage 204, the inner cylinder 220 is provided with an inner cylinder air inlet 221 and an inner cylinder air outlet 222 which are mutually communicated, the inner cylinder air inlet 221 is connected with the cylinder wall of the outer cylinder 210, and the inner cylinder air outlet 222 is arranged adjacent to the outer cylinder air guiding opening 203; the area surrounded by the inner cylinder air inlet 221 is larger than the area surrounded by the inner cylinder air outlet 222;
the outer cylinder air inlet 201 and/or the inner cylinder air inlet 221 are jet air inlets, the outer cylinder air outlet 202 is a jet air outlet, and the outer cylinder air outlet 203 is a jet air outlet.

The air supply pipe 300 is a passage for connecting with the fresh air ejector 200 and supplying air, and may be a separate pipe.
For example, as shown in fig. 1 and fig. 2, the air after heat exchange generated by the heat exchange of the fresh air conditioning integrated machine 100 enters the outer cylinder air inlet 201 through the air conditioner air outlet 121, then enters the air passing channel 204 from the outer cylinder air inlet 201, and because the inner cylinder 220 is arranged in the air passing channel 204, the air enters the inner cylinder 220 through the inner cylinder air inlet 221 and flows out from the inner cylinder air outlet 222, and because the area enclosed by the inner cylinder air inlet 221 is larger than the area enclosed by the inner cylinder air outlet 222, that is, the air flowing out from the inner cylinder 220 is sprayed out in an accelerating way, the air around the inner cylinder air outlet 222 is rolled up by the air sprayed out in an accelerating way at the moment to form partial vacuum, and negative pressure is generated. Air outside the wall of the outer cylinder 210 is pressed into the air passing channel 204 through the outer cylinder air introducing port 203 under the action of atmospheric pressure, and the fresh air is mixed with the air after heat exchange and then continuously input into the room, so that heat exchange and ventilation are realized. The fresh air and the heat exchanged air have reached a comfortable temperature when mixed, thereby avoiding the problem of local overheating caused by the separate introduction of fresh air outside the room.
It can be understood that the outer cylinder air guiding opening 203 is directly opened on the wall of the outer cylinder 210, so as to realize a space outside the air passing channel 204 and the wall of the outer cylinder 210. The inner cylinder air inlet 221 may be connected to the wall of the outer cylinder 210 by separately manufacturing the outer cylinder 210 and the inner cylinder 220, and then adhering the inner cylinder 220 to the inner side of the wall of the outer cylinder 210 by using an adhesive, or integrally forming the outer cylinder 210 and the inner cylinder 220. The fresh air ejector 200 can be made of metal or plastic. When the outer cylinder air inlet 201 and the inner cylinder air inlet 221 are overlapped, both are ejector air inlets; when the air is not overlapped, the air firstly enters the air inlet of the ejector.
According to the fresh air ejector 200, through the matching arrangement of the outer cylinder 210 and the inner cylinder 220, air enters from the outer cylinder air inlet 201 after heat exchange and flows out from the outer cylinder air outlet 202, when the air passes through the inner cylinder 220, the area surrounded by the inner cylinder air inlet 221 is larger than the area surrounded by the inner cylinder air outlet 222, the flow speed is increased when the air flows out of the inner cylinder air outlet 222, negative pressure is formed at the corresponding position of the inner cylinder air outlet 222, external fresh air is pressed into the air passage 204 through the outer cylinder air outlet 203 under the action of external atmospheric pressure, and the air enters an indoor space along with the air after heat exchange, so that the requirements of indoor heat exchange and fresh air introduction are met. According to the embodiment of the utility model, no additional fresh air power component is required to be added, so that the cost is saved, the air supply pipe 300 is directly connected, and the increase of additional volume is avoided.

In the embodiment of the utility model, the air guiding pipe 230 is arranged at the outer cylinder air guiding opening 203, the air inlet of the air guiding pipe 230 can be far away from the heat exhausting area of the air conditioner main body, the fresh air is closer to the outdoor temperature, and the fresh air is mixed with the air after heat exchange after being pressed into the air passing channel 204, so that the influence on temperature fluctuation is reduced. In addition, by arranging the air guiding pipe 230, the negative pressure vacuum degree formed in the area near the air outlet 222 of the inner cylinder is higher, and in the air guiding process, the outside fresh air can advance along the air guiding pipe 230 to enter the air passing channel 204, so that the fresh air is ensured to be inhaled.
Further, in the embodiment of the present utility model, the medium treated by the fresh air ejector 200 is air, so, in order to reduce the obstruction of the fresh air ejector 200 to air, as shown in fig. 3 and 4, the area surrounded by the inner cylinder 220 gradually decreases from the inner cylinder air inlet 221 to the inner cylinder air outlet 222. The area enclosed by the inner cylinder 220 is gradually reduced, namely, the inner cylinder air inlet 221 and the inner cylinder air outlet 222 are in smooth transition, and the resistance of air to change the wind direction is smaller, namely, although the fresh air ejector 220 is arranged, the resistance to the air can be reduced when the air is ensured to be sprayed out in an accelerating way, so that the noise is reduced.
Further, the rate of change of the area enclosed by the inner cylinder 220 is reduced from the inner cylinder air inlet 221 to the inner cylinder air outlet 222. In the utility model, the medium treated by the fresh air ejector 200 is air, and the change rate of the area surrounded by the inner cylinder 220 is larger in the first half section of the inner cylinder 220, namely the degree of area surrounded by the inner cylinder 220 is larger, so that the air can be rapidly pressurized; in the latter half of the inner cylinder 220, the rate of change of the area enclosed by the inner cylinder 220 is smaller, that is, the area enclosed by the inner cylinder 220 is smaller, so that the tangential direction of the air outlet 222 of the inner cylinder tends to be parallel to the wind direction, and the air flowing out of the air outlet 222 of the inner cylinder can be blown out basically in parallel, which is more beneficial to mixing and taking away with the outside fresh air, reduces the air turbulence at the air outlet 222 of the inner cylinder, and reduces noise.
Further, as shown in fig. 3 and 4, the outer cylinder air inlet 201 and the outer cylinder air outlet 202 are formed at both ends of the outer cylinder 210, respectively, and the end of the outer cylinder 210 has a circular cylindrical shape.

Specifically, the sealing portion 212 may be a plurality of spaced annular sealing strips (made of rubber, silica gel, etc.), and the air outlet 121 and the air supply pipe 300 of the air conditioner are sleeved at the end of the outer cylinder 210 and are in interference fit with the plurality of annular sealing strips, so as to form a seal. The sealing portion 212 may be an external thread formed on the outer side of the wall of the outer cylinder 210, the outer cylinder 210 is connected with the air conditioner air outlet 121 and the air supply pipe 300 through the external thread, that is, the end portions of the air conditioner air outlet 121 and the air supply pipe 300 are also provided with the external thread, the external thread is fastened through the nut 400, and meanwhile, the sealing can be realized through the thread, and in this connection manner, the connection between the fresh air ejector 200 and the air conditioner air outlet 121 and the air supply pipe 300 can be ensured to be stable, and the loosening is prevented under the condition of artificial touch. It is understood that the end of the outer tub 210 being connected to the air conditioner outlet 121 means that the end of the outer tub 210 may be connected to the air conditioner outlet 121 through an additional pipe. Further, a gasket (rubber gasket) may be added between both ends of the outer tub 210 and the end surface of the air conditioner outlet 121 and the end surface of the air supply duct 300 to further improve sealability.
