Description

Technical Field

[0001] This application relates to building ventilation control technology, and particularly to curtain walls. Background Art

[0002] A curtain wall is a common exterior wall structure of a building, consisting of a large area of glass panels and a metal frame. Some curtain walls are provided with ventilation openings to facilitate air exchange between the indoor and outdoor. If the wind outside the building is relatively strong, the air velocity and air volume flowing into the building through the ventilation openings are also relatively large, which may blow away items such as documents indoors, resulting in a poor user experience. Summary of the Invention

[0003] To solve the above technical problems, the curtain wall provided in this application can control the ventilation volume and wind speed flowing into the building under different wind speed conditions.

[0004] The curtain wall provided in this application includes a frame body and a glass panel. The glass panel is embedded in the frame body. The frame body is provided with a plurality of ventilation openings. Two groups of wind-blocking movable components are arranged in each ventilation opening. The two groups of wind-blocking movable components are arranged in mirror symmetry. The gap between the two groups of wind-blocking movable components is a ventilation channel. When they approach or move away from each other, the ventilation channel is narrowed or widened. The wind-blocking movable component includes a reset torsion spring and an upwind driving plate, a wind-guiding parallel plate, and a reset driving plate that are sequentially hinged. The first end of the upwind driving plate and the second end of the reset driving plate are respectively hinged to the inner wall of the ventilation opening. The upwind driving plate is pushed by the incoming air flow in the ventilation opening to rotate, so that the two groups of wind-blocking movable components approach each other to narrow the ventilation channel. The reset torsion spring drives the wind-blocking movable component to reset, so that the two groups of wind-blocking movable components move away from each other to widen the ventilation channel.

[0005] Wind-blocking movable components arranged in mirror symmetry are provided in the ventilation openings of the curtain wall. The two groups of wind-blocking movable components can approach or move away from each other to change the size of the ventilation channel, so that the curtain wall can control the ventilation volume flowing into the building under different wind speed conditions. The greater the wind speed of the incoming air in the ventilation opening, the closer the two groups of wind-blocking movable components approach each other, the narrower the ventilation channel, and the less the incoming air volume of the ventilation opening. When the air volume decreases, the wind speed drops rapidly after blowing into the room, avoiding blowing away items such as documents indoors and improving the user experience.

[0006] Further, the wind-guiding parallel plate includes a sound-absorbing rubber plate, and the sound-absorbing rubber plate is arranged on the surface of the wind-guiding parallel plate to reduce the noise generated by the air flow passing through the ventilation channel.

[0007] The air velocity in the ventilation channel increases, and the two symmetrical wind-guiding parallel plates approach each other to narrow the ventilation channel. The high-speed airflow causes air vibration at the vent, resulting in a humming noise. The sharp noise can easily cause discomfort. Sound-absorbing rubber plates are set on both sides of the ventilation channel. Rubber is a high-density, soft and elastic material with good vibration attenuation ability. The sound-absorbing rubber plates can absorb the vibration generated by the airflow passing through the ventilation channel and reduce noise.

[0008] Furthermore, the air-guiding parallel plates also include an air-guiding frame and a plurality of connecting support strips spaced side by side, and the sound-absorbing rubber plates are fixedly connected to the air-guiding frame and the plurality of connecting support strips, respectively, so that when the airflow passes through the ventilation channel, the area where the sound-absorbing rubber plates are not fixedly connected to the air-guiding frame and the connecting support strips is deformed by the air pressure difference on both sides and bulges toward the ventilation channel, and the positions where the sound-absorbing rubber plates on both sides of the ventilation channel are fixedly connected are staggered along the airflow direction of the ventilation channel, so that the bulges formed by the sound-absorbing rubber plates on both sides of the ventilation channel are staggered to form a bent ventilation channel.

[0009] The sound-absorbing rubber sheet is an elastic material that can deform between adjacent connecting support strips. Based on the Bernoulli principle, the greater the air flow speed in the ventilation channel, the greater the air pressure difference on both sides of the sound-absorbing rubber sheet. The area of the sound-absorbing rubber sheet that is not fixedly connected by the air guide frame and the connecting support strip is deformed and bulges toward the ventilation channel, thereby forming a structure with an undulating surface. The positions where the sound-absorbing rubber sheets on both sides of the ventilation channel are deformed and bulged are staggered, so that the ventilation channel changes from a straight road to a curve, which can slow down the wind speed. The greater the wind speed flowing through the ventilation channel, the greater the bulging amplitude of the sound-absorbing rubber sheet. In other words, the sound-absorbing rubber sheet adaptively adjusts the curvature of the surface of the sound-absorbing rubber sheet according to the air flow speed in the ventilation channel, limiting the maximum wind speed blowing into the room through the ventilation channel.

[0010] Furthermore, the connecting support strip is movably connected to the air guide frame and can slide along the air flow direction of the ventilation channel. The first end of the sound-absorbing rubber plate is fixedly connected to the air guide frame, and the second end is fixedly connected to one of the connecting support strips. An elastic reset part is provided between the connecting support strip and the air guide frame to flatten and reset the sound-absorbing rubber plate.

[0011] The connecting support strip can slide along the airflow direction of the ventilation channel, so that the sound-absorbing rubber plate can bulge toward the ventilation channel to a greater extent instead of relying solely on the elasticity of the sound-absorbing rubber plate, thereby further reducing the wind speed and maximum wind speed flowing through the ventilation channel.

[0012] Furthermore, the curtain wall also includes a shaking assembly for shaking the sound-absorbing rubber board, the shaking assembly includes a rotating toggle block and a belt drive mechanism, the belt drive mechanism is connected to the rotating toggle block to drive the rotating toggle block to rotate, the rotating toggle block contacts the sound-absorbing rubber board to cause the sound-absorbing rubber board to deform multiple times when rotating, thereby detaching dust attached to the sound-absorbing rubber board.

[0013] The dust in the air that enters the ventilation duct adheres to the sound-absorbing rubber board due to static electricity. Long-term accumulation can easily lead to bacterial growth, affecting the air quality inside the building. The rotating toggle block is in direct or indirect contact with the sound-absorbing rubber board. When it rotates, the sound-absorbing rubber board can be deformed, which causes the dust attached to the sound-absorbing rubber board to detach, achieving a self-cleaning effect.

[0014] Furthermore, the belt transmission mechanism includes a transmission wheel, a transmission belt and a transmission shaft, the rotating toggle block is sleeved on the transmission shaft, the reset drive plate or the windward drive plate is connected to the transmission wheel, and the transmission wheel is connected to the transmission shaft through the transmission belt to drive the rotating toggle block to rotate.

[0015] The power of the rotating toggle block comes from the reset drive plate or the windward drive plate. When the reset drive plate or the windward drive plate rotates, the transmission wheel is driven to rotate, and the transmission shaft rotates immediately to drive the rotating toggle block to rotate, thereby realizing the overall linkage action and making the design more compact and simple.

[0016] Furthermore, the curtain wall also includes an air filter and a filter ejection assembly, the filter ejection assembly includes a filter return spring and a filter locking mechanism, the air filter can move inward or outward relative to the vent, the windward drive plate is connected to the air filter to pull the air filter inward, the filter locking mechanism is arranged between the air filter and the windward drive plate to lock the air filter, the filter return spring is connected to the air filter to drive the air filter to move outward, when the filter locking mechanism is triggered and unlocked, the filter return spring instantly releases energy to drive the air filter to pop out quickly, thereby causing the air filter to eject large particle pollutants.

[0017] Air filters are installed at the vents to block flying insects or large particles of pollutants outside the building. These large particles of pollutants can easily clog the air filters and affect the ventilation effect. The air filters are designed to be movable so as to move inward or outward relative to the vents. The filter locking mechanism can lock the air filter. When the filter locking mechanism is triggered and unlocked, the filter reset spring is instantly stimulated to push the air filter outward. More precisely, the air filter pops out, thereby causing large particles of pollutants attached to the air filter to pop out, thereby achieving a cleaning effect.

[0018] Furthermore, the filter screen locking mechanism includes a limit catch and a catch spring disposed on the inner wall of the vent. The catch spring is connected to the limit catch to cause the limit catch to pop out of the inner wall of the vent to lock the air filter screen, or the limit catch is pressed back into the inner wall of the vent to unlock the air filter screen. The first end of the limit catch cooperates with the air filter screen to lock the air filter screen, and the second end cooperates with the windward driving plate to unlock the air filter screen.

[0019] The limit catch is disposed at the inner wall of the vent. When the air filter screen slides inward to the first end of the limit catch, the limit catch is pressed back into the inner wall of the vent. After the air filter screen continues to slide inward and passes the first end of the limit catch, the limit catch pops out of the inner wall of the vent under the action of the catch spring, thereby locking the air filter screen. The first end and the second end of the limit catch can be linked. When the second end of the limit catch is pressed back into the inner wall of the vent, the first end of the limit catch also retracts into the inner wall of the vent. Therefore, when the windward driving plate rotates in the opposite direction and presses the second end of the limit catch, the first end of the limit catch retracts into the inner wall of the vent, thereby unlocking the air filter screen. In other words, the windward driving plate triggers the unlocking of the filter screen locking mechanism, and with the cooperation of the filter screen return spring, the air filter screen can be ejected outward.

DETAILED DESCRIPTION

[0029] The present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1-2 As shown, an embodiment of the present application provides a curtain wall, which includes a frame body 100 and a glass panel 200, the glass panel 200 is embedded in the frame body 100, the frame body 100 is provided with a plurality of vents 300, an air filter 400 is arranged on the air inlet side of the vent 300 for isolating flying insects or large particle pollutants, a manual closing door 900 is arranged on the air outlet side of the vent 300, and the vent 300 can be opened or closed manually by manually closing the door 900.

[0031] The curtain wall of the embodiment of the present application can control the ventilation volume and wind speed flowing into the interior of the building under different wind speed conditions. Figure 3 and Figure 4As shown, the curtain wall of the embodiment of the present application is provided with two groups of wind-shielding movable components 500 in each vent 300, and the two groups of wind-shielding movable components 500 are arranged in mirror symmetry, and the gap between the two groups of wind-shielding movable components 500 is a ventilation channel 800, which shrinks or expands the ventilation channel 800 when they are close to or away from each other, and the wind-shielding movable component 500 includes a reset torsion spring 520 and a windward driving plate 510, a wind-guiding parallel plate 540, and a reset driving plate 530 which are hinged in sequence, and the first end of the windward driving plate 510 and the second end of the reset driving plate 530 are respectively hinged to the inner wall of the vent 300, and the windward driving plate 510, the wind-guiding parallel plate 540, the reset driving plate 530 and the inner wall of the vent 300 together form a quadrilateral. The structure includes a windward driving plate 510, a wind-guiding parallel plate 540 and a reset driving plate 530, and the windward driving plate 510 is driven by the airflow from the vent 300 to rotate. The greater the speed of the airflow, the greater the amplitude of the rotation of the windward driving plate 510. The wind-guiding parallel plate 540 hinged to the windward driving plate 510 is linked accordingly. The two groups of wind-guiding parallel plates 540 approach each other, and the relative distance decreases. The two groups of wind-shielding movable components 500 thus approach each other and narrow the ventilation passage 800. The speed of the airflow decreases, and the driving force of the airflow on the windward driving plate 510 decreases. The reset torsion spring 520 drives the wind-shielding movable component 500 to reset. The two groups of wind-shielding movable components 500 thus move away from each other and expand the ventilation passage 800. The reset torsion spring 520 can be set at the angle of the quadrilateral formed together, such as Figure 3 and Figure 4 In the embodiment, a plurality of reset torsion springs 520 are provided, which are respectively provided at the angles between the reset driving plate 530 and the inner wall of the vent 300 to drive the reset driving plate 530 to rotate, so that the two sets of wind guiding parallel plates 540 move away from each other, thereby expanding the ventilation channel 800.

[0032] As shown above, mirror-symmetrical wind-shielding movable components 500 are arranged in the vent 300 of the curtain wall. The two sets of wind-shielding movable components 500 can be moved closer to or farther away from each other to change the size of the ventilation channel 800, so that the curtain wall can control the ventilation volume flowing into the interior of the building under different wind speed conditions. The greater the wind speed of the air entering the vent 300, the closer the two sets of wind-shielding movable components 500 are to each other, the narrower the ventilation channel 800 is, and the smaller the air intake of the vent 300 is. When the air volume is reduced, the wind speed drops rapidly after blowing into the room, thereby avoiding blowing away documents and other items in the room, thereby improving the user experience.

[0033] The air flow speed of the ventilation channel 800 increases, and the two symmetrical wind guide parallel plates 540 approach each other to reduce the ventilation channel 800. The high-speed air flow causes air vibration at the vent 300, resulting in a humming noise. The sharp noise can easily cause discomfort. Figure 4It is shown that the air guiding parallel plate 540 of the embodiment of the present application includes a sound-absorbing rubber plate 542, and the sound-absorbing rubber plate 542 is disposed on the surface of the air guiding parallel plate 540 to reduce the noise generated by the airflow passing through the ventilation channel 800. That is, in the embodiment of the present application, the sound-absorbing rubber plates 542 are disposed on both sides of the ventilation channel 800. Rubber is a material with high density, softness and elasticity, and has good vibration attenuation ability. The sound-absorbing rubber plate 542 can absorb the vibration generated by the airflow passing through the ventilation channel 800 and reduce the noise.

[0034] Further, as Figure 4 and Figure 5 shown are the schematic structural diagrams of two usage states of the embodiment of the present application. Figure 4 The surface of the sound-absorbing rubber plate 542 in Figure 5 is relatively flat, and the surface of the sound-absorbing rubber plate 542 in Figure 5 and Figure 6 is a wavy structure. In the embodiment of the present application, the curvature of the surface of the sound-absorbing rubber plate 542 can be adaptively adjusted according to the magnitude of the airflow velocity in the ventilation channel 800 to limit the maximum wind speed blown into the room through the ventilation channel 800. Specifically, as Figure 5 and Figure 6 shown, the air guiding parallel plate 540 further includes an air guiding frame 543 and a plurality of connecting support bars 541 arranged side by side at intervals. The sound-absorbing rubber plate 542 is fixedly connected to the air guiding frame 543 and the plurality of connecting support bars 541 respectively, so that the area of the sound-absorbing rubber plate 542 not fixedly connected to the air guiding frame 543 and the connecting support bars 541 deforms under the action of the air pressure difference on both sides when the airflow flows through the ventilation channel 800 and bulges towards the ventilation channel 800. The positions where the sound-absorbing rubber plates 542 on both sides of the ventilation channel 800 are fixedly connected are staggered along the airflow direction of the ventilation channel 800, so that the bulges formed by the sound-absorbing rubber plates 542 on both sides of the ventilation channel 800 are staggered with each other to form a bent ventilation channel 800. Based on Bernoulli's principle, the greater the airflow velocity in the ventilation channel 800, the greater the air pressure difference on both sides of the sound-absorbing rubber plate 542. The air pressure on the side of the sound-absorbing rubber plate 542 close to the ventilation channel 800 is often relatively small. The sound-absorbing rubber plate 542 is an elastic material and deforms in the non-fixed area. For example, the area of the sound-absorbing rubber plate between adjacent connecting support bars 541 can deform, and the area of the sound-absorbing rubber plate between the connecting support bar and the air guiding frame body can deform. That is, the area of the sound-absorbing rubber plate 542 not fixedly connected to the air guiding frame 543 and the connecting support bars 541 is deformed by the force and bulges towards the ventilation channel 800, and the sound-absorbing rubber plate 542 thus forms a wavy surface structure. The connecting support bars 541 on both sides are arranged in a staggered and spaced manner, so that the positions where the sound-absorbing rubber plates 542 on both sides of the ventilation channel 800 deform and bulge are staggered with each other, making the ventilation channel 800 change from a straight channel to a curved channel, which can slow down the wind speed. The greater the wind speed flowing through the ventilation channel 800, the greater the bulging amplitude of the sound-absorbing rubber plate 542, and further the maximum wind speed blown into the room through the ventilation channel 800 is limited.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a plurality of connecting support strips 541 are disposed on an air guide frame 543, and the connecting support strips 541 are movably connected to the air guide frame 543 and can slide along the airflow direction of the ventilation passage 800, a first end of the sound-absorbing rubber plate 542 is fixedly connected to the air guide frame 543, and a second end of the sound-absorbing rubber plate 542 is fixedly connected to one of the connecting support strips 541, and an elastic reset member 560 is provided between the connecting support strip 541 and the air guide frame 543 to flatten and reset the sound-absorbing rubber plate 542. In other words, the connecting support strips 541 can slide along the airflow direction of the ventilation passage 800, so that the sound-absorbing rubber plate 542 can bulge toward the ventilation passage 800 to a greater extent, instead of relying solely on the elasticity of the sound-absorbing rubber plate 542, and can further reduce the wind speed and the maximum wind speed flowing through the ventilation passage 800. Figure 3 As shown, one end of the elastic reset member 560 is connected to a connecting support strip 541 arranged at the edge of the air guide frame 543, and the other end of the elastic reset member 560 is connected to the air guide frame 543. The second end of the sound-absorbing rubber plate 542 is fixed to the connecting support strip 541. The elastic reset member 560 can push the connecting support strip 541 to reset so as to reset the sound-absorbing rubber plate 542. The elastic reset member 560 can be set as a spring member.

[0036] The dust in the air entering the ventilation passage 800 adheres to the sound-absorbing rubber plate 542 due to static electricity. Long-term accumulation can easily lead to bacterial growth, affecting the air quality inside the building. The embodiment of the present application provides a shaking assembly 600 to shake the sound-absorbing rubber plate 542 to remove the dust accumulated on the sound-absorbing rubber plate 542. Figure 4 , Figure 5 and Figure 8 As shown, the embodiment of the present application also includes a shaking assembly 600 for shaking the sound-absorbing rubber plate 542. The shaking assembly 600 includes a rotating toggle block 610 and a belt transmission mechanism 620. The belt transmission mechanism 620 is connected to the rotating toggle block 610 to drive the rotating toggle block 610 to rotate. The rotating toggle block 610 contacts the sound-absorbing rubber plate 542 to deform the sound-absorbing rubber plate 542 multiple times during rotation, thereby separating the dust attached to the sound-absorbing rubber plate 542. The rotating toggle block 610 is in direct or indirect contact with the sound-absorbing rubber plate 542. When it rotates, it can deform the sound-absorbing rubber plate 542, thereby causing the dust attached to the sound-absorbing rubber plate 542 to separate, thereby achieving a self-cleaning effect.

[0037] Furthermore, if Figure 8As shown, the belt transmission mechanism 620 includes a transmission wheel 621, a transmission belt 623 and a transmission shaft 622, the rotating toggle block 610 is sleeved on the transmission shaft 622, the reset drive plate 530 or the windward drive plate 510 is transmission-connected to the transmission wheel 621, and the transmission shaft 622 is transmission-connected to the transmission wheel 621 through the transmission belt 623 to drive the rotating toggle block 610 to rotate. The power of the rotating toggle block 610 comes from the reset drive plate 530 or the windward drive plate 510. When the reset drive plate 530 or the windward drive plate 510 rotates, the transmission wheel 621 is driven to rotate, and the transmission shaft 622 rotates immediately to drive the rotating toggle block 610 to rotate, thereby realizing the overall linkage action, and the design is more compact and simple.

[0038] The rotating toggle block 610 of the embodiment of the present application can perform circular motion, such as Figure 4 or Figure 5 As shown, the rotating toggle block 610 is provided with a connecting support bar 541 on one side. Since the connecting support bar 541 is movably connected to the air guide frame, when the rotating toggle block 610 rotates, the block on the rotating toggle block 610 directly and periodically toggles the connecting support bar 541, and the connecting support bar 541 slides slightly on the air guide frame, thereby deforming the sound-absorbing rubber plate 542 fixed to the connecting support bar 541. Based on the elasticity of the sound-absorbing rubber plate 542 itself and the reset elastic member, the sound-absorbing rubber plate 542 rebounds. The rotating toggle block 610 rotates once, and the sound-absorbing rubber plate 542 can be deformed multiple times, thereby separating the dust attached to the sound-absorbing rubber plate 542. In some optional embodiments, the rotating toggle block 610 can also be configured to directly toggle the sound-absorbing rubber plate 542 to deform it multiple times. In other optional embodiments, the rotating toggle block 610 can also be a cylindrical gear structure, which cooperates with the air guide frame to cause the air guide frame to vibrate multiple times through rotation and interaction between gears. The sound-absorbing rubber plate 542 also vibrates and slightly deforms multiple times, thereby causing dust to separate from the sound-absorbing rubber plate 542.

[0039] The air filter 400 is provided at the vent 300 to block flying insects or large particles of pollutants outside the building. These large particles of pollutants can easily clog the air filter 400 and affect the ventilation effect. The embodiment of the present application is provided with a filter ejection assembly 700 to eject large particles of pollutants attached to the air filter 400 to achieve a cleaning effect. Specifically, Figure 4 , Figure 5 and Figure 7As shown in the figure, the embodiment of the present application further includes a filter screen ejection assembly 700. The filter screen ejection assembly 700 includes a filter screen return spring 720 and a filter screen locking mechanism 710. The air filter screen 400 can move inwards or outwards relative to the ventilation opening 300. The windward driving plate 510 is connected to the air filter screen 400 to pull the air filter screen 400 inwards. The filter screen locking mechanism 710 is arranged between the air filter screen 400 and the windward driving plate 510 to lock the air filter screen 400. The filter screen return spring 720 is connected to the air filter screen 400 to drive the air filter screen 400 outwards. When the filter screen locking mechanism 710 is triggered to unlock, the filter screen return spring 720 instantaneously releases energy to drive the air filter screen 400 to quickly eject outwards, so that the air filter screen 400 ejects large particulate pollutants. In the embodiment of the present application, the air filter screen 400 is designed to be movable and can move inwards or outwards relative to the ventilation opening 300. The filter screen locking mechanism 710 can lock the air filter screen 400. When the filter screen locking mechanism 710 is triggered to unlock, the filter screen return spring 720 is instantaneously activated to push the air filter screen 400 outwards. More precisely, the air filter screen 400 ejects outwards, so that the large particulate pollutants attached to the air filter screen 400 are ejected, achieving a cleaning effect. More specifically, when the air flow velocity in the ventilation passage 800 increases, the windward driving plate 510 rotates, and the air filter screen 400 connected to the windward driving plate 510 is pulled inwards. After passing through the filter screen locking mechanism 710, the air filter screen 400 is locked by the filter screen locking mechanism 710. At this time, the filter screen return spring 720 is compressed to store energy. When there is no air flow or the air flow velocity in the ventilation passage 800 decreases, the windward driving plate 510 rotates in the opposite direction, the pulling force on the air filter screen 400 decreases, triggering the filter screen locking mechanism 710 to unlock, and the filter screen return spring 720 instantaneously releases energy to push the air filter screen 400 outwards. The large particulate pollutants attached to the air filter screen 400 are removed or loosened due to inertia and impact force. In short, by designing the filter screen locking mechanism 710 on the sliding path of the air filter screen 400 and cooperating with the windward driving plate 510 and the filter screen return spring 720, the air filter screen 400 can be ejected outwards, reducing the blockage caused by the attachment of large particulate pollutants on the air filter screen 400 and improving the self-cleaning effect.

[0040] Further, as Figure 7 shown, the filter screen locking mechanism 710 includes a limit block 711 arranged on the inner wall of the ventilation opening 300 and a block spring 712. The block spring 712 is connected to the limit block 711 to make the limit block 711 pop out of the inner wall of the ventilation opening 300 to lock the air filter screen 400, or the limit block 711 is pressed back into the inner wall of the ventilation opening 300 to unlock the air filter screen 400, as Figure 7As shown, the second end of the limit block is higher than the first end of the limit block. The first end of the limit block 711 cooperates with the air filter 400 to lock the air filter 400, and the second end of the limit block 711 cooperates with the windward driving plate 510 to unlock the air filter 400. The limit block 711 is arranged at the inner wall of the ventilation opening 300. When the air filter 400 slides inward to the first end of the limit block 711, the air filter 400 exerts a downward force on the first end of the limit block 711, and the limit block 711 is pressed back to the inner wall of the ventilation opening 300. After the air filter 400 continues to slide inward and passes through the first end of the limit block 711, the limit block 711 pops out of the inner wall of the ventilation opening 300 under the action of the block spring 712, thereby locking the air filter 400. The first end and the second end of the limit block 711 can be linked. When the second end of the limit block 711 is pressed back to the inner wall of the ventilation opening 300, the first end of the limit block 711 also retracts into the inner wall of the ventilation opening 300. Therefore, when the windward driving plate 510 rotates in the opposite direction and presses the second end of the limit block 711, a downward force is applied to the second end of the limit block 711, and the first end of the limit block 711 retracts into the inner wall of the ventilation opening 300, thereby unlocking the air filter 400. In other words, the windward driving plate 510 triggers the unlocking of the filter locking mechanism 710, and with the cooperation of the filter return spring 720, the air filter 400 can be ejected outward.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention.
