The shell 300 is provided with a fresh air inlet 330 and a fresh air outlet 340 communicated with the fresh air inlet 330; one end of the fresh air duct 700 is adapted to be connected to the fresh air inlet 330 and the other end of the fresh air duct 700 is adapted to communicate with the outdoor environment. Wherein, the periphery of the fresh air inlet 330 is configured with an inner annular wall 331 and an outer annular wall 332 (as shown in fig. 4 and 5) located at the periphery of the inner annular wall 331, and a slot 333 is formed between the outer annular wall 332 and the inner annular wall 331; the fresh air duct 700 is adapted to be inserted into the slot 333 of the fresh air inlet 330.
Specifically, a fresh air duct is formed inside the housing 300 of the fresh air module 200, and the fresh air duct simplifies the communication between the fresh air inlet 330 and the fresh air outlet 340. The housing 300 includes a bottom case 310 and a case cover 320 adapted to cover the bottom case 310. The fresh air module 200 is also provided with a middle partition plate 600 in the fresh air duct, and the fresh air duct is divided into an air inlet cavity and an air outlet cavity by the middle partition plate 600; the middle partition plate 600 is provided with a vent hole 610 for communicating the air inlet chamber and the air outlet chamber. The bottom of the shell 300 can be provided with a fresh air inlet 330, and the fresh air inlet 330 is communicated with the air inlet cavity; the casing 300 may be provided with a fresh air outlet 340 at the top or the front side or the left side or the right side, and the fresh air outlet 340 is communicated with the air outlet cavity.
Optionally, the housing 300 is provided with a fresh air inlet 330 at the bottom thereof, and is open to the rear side of the fresh air module 200 to allow air to enter from the rear; the casing 300 is provided at a front side thereof with a fresh air outlet 340 to supply air toward the front side of the fresh air module 200. When the fresh air module 200 works, outdoor fresh air enters from the fresh air pipe 700, enters the fresh air duct of the housing 300 through the fresh air inlet 330, is purified by the purification assembly 500 in the fresh air duct, and is blown out through the fresh air outlet 340.
In the technical solution of the present invention, the inner annular wall 331 and the outer annular wall 332 are configured around the fresh air inlet 330 of the casing 300, so that the inner annular wall 331 and the outer annular wall 332 are combined into a double-layer tube structure, and the slot 333 opened outward is formed between the inner annular wall 331 and the outer annular wall 332. During assembly, the pipe orifice at one end of the fresh air pipe 700 is inserted into the slot 333 of the fresh air inlet 330, and the inner ring wall 331 and the outer ring wall 332 on the two sides of the slot 333 are matched with each other to clamp and limit the movement of the fresh air pipe 700, so that the fresh air pipe 700 is not easy to fall off, the falling-off of a new branch pipe is reduced, and the installation stability of the fresh air pipe 700 is improved.
Referring to fig. 3 to 5, in an embodiment, the fresh air duct 700 may be directly inserted into the slot 333 of the fresh air inlet 330; it is contemplated that if the fresh air duct 700 is made of a flexible or resilient material, the fresh air duct 700 can be over-flexed to receive the fresh air duct 700 or to adapt the fresh air duct 700 for assembly to different buildings. The fresh air duct 700 made of these materials is soft, and the slot 333 formed between the inner annular wall 331 and the outer annular wall 332 of the fresh air inlet 330 is narrow, so that the fresh air duct 700 is not easily inserted into the slot 333 of the fresh air inlet 330.
Referring to fig. 6 to 8, in order to solve the above technical problem, the fresh air module 200 further includes a pipe connector 800 disposed at one end of the fresh air pipe 700, and the fresh air pipe 700 is inserted into the slot 333 of the fresh air inlet 330 through the pipe connector 800. The pipe connector 800 has a first connector 810 and a second connector 820, the first connector 810 is connected with the fresh air pipe 700, and the second connector 820 is inserted into the slot 333 of the fresh air inlet 330.
In particular, the pipe joint member 800 is generally made of a hard material, so that the pipe joint member 800 has a strong strength. The first port 810 of the pipe connector 800 is fixedly connected to the fresh air pipe 700, and the second port 820 of the pipe connector 800 is directly inserted into the slot 333 of the fresh air inlet 330, so that the fresh air pipe 700 is connected to the fresh air inlet 330 through the pipe connector 800. Since the pipe joint 800 has a strong strength, it is not easily deformed during the process of inserting the second port 820 of the pipe joint 800 into the slot 333, and thus it can be strongly inserted into the slot 333; at this time, the inner ring wall 331 and the outer ring wall 332 of the fresh air inlet 330 cooperate to strongly clamp and fix the second port 820 of the pipe connector 800, so that the pipe connector 800 is not easy to fall off, and the stability of installing a new branch pipe is ensured.
As for the pipe joint 800, the pipe joint 800 may be provided as an L-shaped or C-shaped bent pipe as a whole or as a straight pipe having a straight cylindrical shape. Specifically, the pipe connector is arranged as a C-shaped elbow, the first connector 810 of the pipe connector 800 is connected to the fresh air inlet 330, and the second connector 820 is connected to the fresh air pipe 700.
Referring to fig. 8 to 10, in an embodiment, a positioning rib 830 is protruded on an outer wall surface of the pipe connector 800, and the positioning rib 830 extends along an axial direction of the pipe connector 800 in a long strip shape; the inner side surface of the outer annular wall 332 of the fresh air inlet 330 is configured with a positioning groove 334, and the positioning groove 334 extends along the depth direction of the slot 333, so that the positioning ribs 830 are correspondingly inserted and positioned.
During assembly, the second port 820 of the pipe connector 800 is aligned with the slot 333 on the circumference of the fresh air inlet 330; meanwhile, the positioning ribs 830 of the pipe connector 800 are aligned with the positioning grooves 334 on the outer annular wall 332 of the fresh air inlet 330, so that the positioning ribs 830 and the positioning grooves 334 are aligned; then, the second hub 820 of the pipe connector 800 is pushed into the slot 333, and the second hub 820 is fully inserted into the slot 333, and at the same time, the positioning ribs 830 are correspondingly inserted into the positioning grooves 334. Due to the matching of the positioning ribs 830 of the pipe connector 800 and the positioning grooves 334 of the fresh air inlet 330, the rotation of the pipe connector 800 is limited, so that the fresh air inlet 330 of the pipe connector 800 can be guided to be inserted or drawn out in the inward and outward (axial) directions, the assembly difficulty is reduced, and the assembly efficiency is improved.
Referring to fig. 5, 7 and 8, further, an annular rib 840 is protruded from the outer peripheral wall of the pipe connector 800, the annular rib 840 is located at a side of the positioning rib 830 away from the first port 810, and the annular rib 840 extends along the circumference of the pipe connector 800 to be adapted to abut against the outer end surface of the outer annular wall 332.
Specifically, the tubular connector 800 may be divided from the annular bead 840 into a first portion corresponding to the first hub 810 and a second portion corresponding to the second hub 820. During assembly, an assembler may hold the first portion of the coupling 800 and push the second port 820 of the coupling 800 into the slot 333 until the annular rib 840 contacts and abuts the outer annular wall 332 outside the slot 333, completing the installation of the coupling 800. That is, the annular bead 840 may provide an indication to the assembler that the fitting 800 is in place when it contacts and abuts the outer annular wall 332. In addition, if the insertion force of the assembling person is too large, the outer annular wall 332 only impacts the annular rib 840, and the outer annular wall 332 does not impact the hand of the assembling person, so that the operation safety of the assembling person is protected.
