The air exhaust pipe includes an air exhaust channel formed in the air exhaust pipe. One end of the connection pipe is connected to a lower end of the air exhaust pipe and another end of the connection pipe is configured to be connected to an air exhaust volute of a packaged air conditioner, such that the air exhaust channel is communicated with an air outlet of the air exhaust volute. An air intake channel is formed between an inner wall of the air intake pipe and an outer wall of the air exhaust pipe, and the air intake channel is communicated with an air inlet of the packaged air conditioner. ## Claims ### Claim 1 An air intake and exhaust assembly comprising: an air exhaust pipe, including an air exhaust channel formed in the air exhaust pipe; a connection pipe, one end of the connection pipe being connected to a lower end of the air exhaust pipe and another end of the connection pipe being configured to be connected to an air exhaust volute of a packaged air conditioner, such that the air exhaust channel is communicated with an air outlet of the air exhaust volute; an air intake pipe arranged adjacent to the air exhaust pipe, an air intake channel being formed between an inner wall of the air intake pipe and an outer wall of the air exhaust pipe, and the air intake channel being communicated with an air inlet of the packaged air conditioner; and a sealing plate including: an air intake hole connected to one end of the air intake pipe away from the air inlet; a fixation ring arranged in the air intake hole; and an air exhaust hole connected to one end of the air exhaust pipe away from the air outlet, wherein the air intake hole surrounds the air exhaust hole, and the fixation ring is between the air intake hole and the air exhaust hole. ### Claim 2 (depends on 1) The air intake and exhaust assembly according to claim 1, wherein the one end of the connection pipe is provided with an installation port, and the lower end of the air exhaust pipe is provided with a joint matching the installation port. ### Claim 3 (depends on 2) The air intake and exhaust assembly according to claim 2, wherein the installation port is provided with a plurality of buckles arranged at intervals along a circumferential direction of the installation port, and the plurality of buckles are clamped with the joint. ### Claim 4 (depends on 1) The air intake and exhaust assembly according to claim 1, wherein the air inlet is provided with an installation port, and one end of the air intake pipe facing the air inlet is provided with a joint matching the installation port. ### Claim 5 (depends on 4) The air intake and exhaust assembly according to claim 4, wherein the installation port is provided with a plurality of buckles arranged at intervals along a circumferential direction of the installation port, and the plurality of buckles are clamped with the joint. ### Claim 6 (depends on 1) The air intake and exhaust assembly according to claim 1, further comprising: a connection rib arranged between the fixation ring and the sealing plate. ### Claim 7 (depends on 1) The air intake and exhaust assembly according to claim 1, further comprising: a plurality of connection ribs arranged between the fixation ring and the sealing plate and arranged at intervals along a circumferential direction of the fixation ring. ### Claim 8 (depends on 1) The air intake and exhaust assembly according to claim 1, wherein each of the air exhaust pipe, the connection pipe, and the air intake pipe is cylindrical. ### Claim 9 A packaged air conditioner comprising: an air exhaust volute; and an air intake and exhaust assembly including: an air exhaust pipe, including an air exhaust channel formed in the air exhaust pipe; a connection pipe, one end of the connection pipe being connected to a lower end of the air exhaust pipe and another end of the connection pipe being configured to be connected to the air exhaust volute, such that the air exhaust channel is communicated with an air outlet of the air exhaust volute; an air intake pipe arranged adjacent to the air exhaust pipe, an air intake channel being formed between an inner wall of the air intake pipe and an outer wall of the air exhaust pipe, and the air intake channel being communicated with an air inlet of the packaged air conditioner; and a sealing plate including: an air intake hole connected to one end of the air intake pipe away from the air inlet; a fixation ring arranged in the air intake hole; and an air exhaust hole connected to one end of the air exhaust pipe away from the air outlet, wherein the air intake hole surrounds the air exhaust hole, and the fixation ring is between the air intake hole and the air exhaust hole. ### Claim 10 (depends on 9) The packaged air conditioner according to claim 9, wherein the one end of the connection pipe is provided with an installation port, and the lower end of the air exhaust pipe is provided with a joint matching the installation port. ### Claim 11 (depends on 10) The packaged air conditioner according to claim 10, wherein the installation port is provided with a plurality of buckles arranged at intervals along a circumferential direction of the installation port, and the plurality of buckles are clamped with the joint. ### Claim 12 (depends on 9) The packaged air conditioner according to claim 9, wherein the air inlet is provided with an installation port, and one end of the air intake pipe facing the air inlet is provided with a joint matching the installation port. ### Claim 13 (depends on 12) The packaged air conditioner according to claim 12, wherein the installation port is provided with a plurality of buckles arranged at intervals along a circumferential direction of the installation port, and the plurality of buckles are clamped with the joint. ### Claim 14 (depends on 9) The packaged air conditioner according to claim 9, wherein the air intake and exhaust assembly further includes: a connection rib arranged between the fixation ring and the sealing plate. ### Claim 15 (depends on 9) The packaged air conditioner according to claim 9, wherein the air intake and exhaust assembly further includes: a plurality of connection ribs arranged between the fixation ring and the sealing plate and arranged at intervals along a circumferential direction of the fixation ring. ### Claim 16 (depends on 9) The packaged air conditioner according to claim 9, wherein each of the air exhaust pipe, the connection pipe, and the air intake pipe is cylindrical.
