[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 and Figure 2 As shown, the utility model is an air outlet structure of a curtain wall ventilator, comprising a shell 10 with a top opening and an accommodating cavity 9 inside, and a cover plate 11 rotatably connected to the opening.

[0030] like Figure 1 As shown, the housing 10 is a rectangular structure. The housing 10 is formed by a bottom plate 101 and four wall plates 102 fixed on the surface of the bottom plate 101, namely, the front, rear, left and right wall plates 102.

[0031] like Figure 1 and Figure 3 As shown, a plurality of air inlets 103 are provided on the bottom plate 101, and a plurality of ventilation holes 104 are provided on the left and right wall plates 102, respectively. In this way, fresh air enters from the air inlet 103, and exchanges air with the room through the plurality of ventilation holes 104 on the left and right wall plates 102. With this structure, fresh air can be effectively introduced and dirty air can be discharged, thereby improving the indoor air quality. Compared with the prior art, air circulation can be smoother and ventilation effect can be improved. At the same time, air can be circulated indoors, reducing the temperature difference between indoors and outdoors and enhancing thermal insulation performance. In the present embodiment, the ventilation holes 104 are rectangular structures. Of course, the ventilation holes can be designed into different shapes and quantities according to actual needs.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a movable baffle 13 adapted to the air inlet 103 is provided in the accommodating cavity 9. The movable baffle 13 can block the corresponding air inlet 104. A control switch 20 connected to the movable baffle 13 is also included. The control switch 20 can drive the movable baffle 13 to rise and fall, thereby controlling the movable baffle 13 to open or close the air inlet 103.

[0033] Combination Figure 6 As shown, the control switch 20 includes a power component 21 and a lifting component 22.

[0034] Combination Figure 7 As shown, the power assembly 21 includes a sliding member 211 and a gear 212 disposed in the accommodating chamber 9. The sliding member 211 has a square hole 214, and a rack 213 meshing with the gear 212 is disposed on one side wall of the square hole 214. The movable baffle 13 is connected to the sliding member 211 through a connecting member 131. One end of the connecting member 131 is hinged to the sliding baffle 13, and the other end is hinged to the sliding member 211. The rotating gear 212 drives the sliding member 211 to move linearly.

[0035] like Figure 1 As shown, in this embodiment, there are two movable baffles 13. The two movable baffles 13 are hinged to the left and right ends of the sliding member 211 through connecting members 131 respectively.

[0036] like Figure 7As shown, the support plate 23 has a notch 231 in the middle, and guide rails 232 are provided on the left and right edges of the notch 231. The left and right edges of the sliding member 211 have sliding grooves assembled on the guide rails 232. With this structure, when the sliding member 211 moves in the guide rails 232, the guide rails 232 can play a role of stabilization and support, making the sliding member more stable during the movement process.

[0037] like Figure 5 and Figure 7 As shown, a panel 26 is provided at the notch on the support plate 23. The panel 26 has a mounting hole corresponding to the position of the gear 212. The gear 212 is installed in the mounting hole.

[0038] like Figure 7 As shown, a positioning member 24 is provided at the middle position of the left and right side walls of the guide rail 232. Each positioning member 24 includes a positioning block 241, a spring (not shown in the figure) and a positioning bead 242.

[0039] The positioning block 241 is provided with a positioning hole (not shown in the figure). A spring is arranged in the corresponding positioning hole. One end of the spring abuts against the inner end surface of the positioning hole, and the other end abuts against the positioning bead 242. A plurality of positioning grooves 245 matching with the corresponding positioning beads are respectively arranged on the left and right edges of the sliding member 211. In this embodiment, two positioning grooves 245 (i.e., a front positioning groove 245a and a rear positioning groove 245b) are respectively arranged on the left and right edges of the sliding member 211. The positioning bead 242 is pushed out by the action of the spring and fits with the positioning groove 245, thereby playing a positioning role in the sliding of the sliding member 211 in the guide rail.

[0040] like Figure 5 and Figure 7 As shown, the lifting assembly 22 includes a lifting adjustment block group 25 and a plurality of pins 28 symmetrically arranged on the left and right sides of the movable baffle.

[0041] like Figure 7 and Figure 8As shown, each lifting and lowering adjustment block group 25 is composed of a plurality of lifting and lowering adjustment blocks 251 arranged at intervals. A guide groove 252 for sliding the movable baffle 13 is obliquely arranged on each lifting and lowering adjustment block 251. The guide groove 252 has a rail surface, which is divided into an upper horizontal rail surface 253, a lower horizontal rail surface 254, and a slope surface 255 connected between the upper horizontal rail surface 253 and the lower horizontal rail surface 254. Each pin shaft 28 passes through the bottom of the movable baffle 13 respectively. Rollers 29 are respectively sleeved on both ends of the pin shaft 28. Each roller 29 is located in the guide groove 252 of the corresponding lifting and lowering adjustment block 251. The roller 29 is used to slide in the guide groove 252 and support the movable baffle 13. In this way, the gear 212 is rotated to drive the sliding member 211 to translate. Since the roller 29 on the pin shaft 28 connected to the movable baffle 13 is located in the guide groove 252, and the guide groove 252 is inclined, the guide groove 252 of the lifting and lowering adjustment block 251 will cause the movable baffle 13 to rise or fall during the translation of the movable baffle 13. When the movable baffle 13 rises, the movable baffle 13 will open the air inlet 103, and when the movable baffle 13 falls, the air inlet 103 will be blocked.

[0042] Thus, when the roller 29 is located at the lower horizontal rail surface 254 (i.e., the movable baffle 13 is at a low position), the positioning beads 242 in the positioning member 24 are located in the rear positioning groove 245b, and the movable baffle 13 blocks the air inlet 103. When the roller 29 is located at the upper horizontal rail surface 253 (i.e., the movable baffle 13 is at a high position), the positioning beads 242 in the positioning member 24 are located in the front positioning groove 245a, and the movable baffle 13 opens the air inlet 103. Since there is a gap between the movable baffle 13 and the inner wall of the housing 10, fresh air enters from the air inlet 103, passes through the gap, and exchanges air with the room through the multiple ventilation holes 104 on the left and right wall panels 102.

[0043] like Figure 2 and Figure 4 As shown, in addition, an operating hole 111 is provided on the cover plate 11 at a position directly opposite to the gear 212. A knob 27 connected to the gear 212 is embedded in the operating hole 111. Thus, by turning the knob 27, the gear 212 rotates synchronously, and the teeth on the outer edge of the gear 212 mesh with the rack of the sliding member 211, driving the sliding member 211 to move linearly.

[0044] like Fig. 9 As shown, a top cover 8 is also connected to the open portion of the housing 10. The top cover 8 is located above the cover plate 11. In this way, by adding a top cover 8, the cover plate 11 and the knob 27 are hidden, making the overall appearance of the ventilator more beautiful.

[0045] In summary, the utility model can make air flow smoother and improve ventilation effect by opening multiple ventilation holes on the left and right wall panels. At the same time, the control switch can drive the movable baffle to rise and fall, thereby controlling the movable baffle to open or close the air inlet. Adding a top cover to hide the cover plate and the knob makes the overall appearance of the ventilator more beautiful. The structure is reasonable and easy to use.

[0046] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
