[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. If not specifically specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] Such as Figures 1-5As shown in the figure, the window ventilator of the periscope air duct is installed at the window position and fixed on the window sill. It includes an air outlet duct 1 and an air inlet duct 2. The air inlet duct 2 includes a first vertical section 205, and the air outlet duct 1 includes a second vertical section 102. The first vertical section 205 and the second vertical section 102 are closely attached to each other. The air outlet duct 1 also includes a grille 101 and a third horizontal section 105. A grille 101 is provided on the side wall near the interior at the bottom of the second vertical section 102, and the third horizontal section 105 communicates with the top of the second vertical section 102. The air inlet duct 2 also includes a first horizontal section 208, and the first horizontal section 208 communicates with the bottom of the first vertical section 205. The third horizontal section 105 is arranged at the top of the first vertical section 205, and the second vertical section 102 is arranged at the top of the first horizontal section 208. An axial flow fan 6, a heat exchange device 5 (coinciding with the heat exchange chamber 206), and a dust removal device 4 are sequentially arranged from top to bottom in the first horizontal section 208. The air outlet of the axial flow fan 6 is parallel to the first horizontal section 208. A negative ion generator 3 is fixedly arranged in the first horizontal section 208, and an axial flow fan group 7 is fixedly arranged in the third horizontal section 105. The arrangement direction of the axial flow fan group 7 is parallel to the third horizontal section 105. The negative ion generator 3 and the axial flow fan group 7 are electrically connected to a control unit, and the control unit controls their working conditions. In another embodiment, a temperature detection and heating device is also provided in the first horizontal section 208 to further heat the inhaled air to an appropriate temperature, where the control unit can be an infrared remote control, a mobile phone, etc. Among them, when the axial flow fan group 7 works, the indoor air enters the lower half of the second vertical section 102 through the grille 101, is guided into the heat exchange chamber 206 through the first arc-shaped deflector 102 to exchange heat with the air in the Tesla valve pipe 503, and then is re-guided into the upper half of the second vertical section 102 through the second arc-shaped deflector 104 and discharged to the outside through the third horizontal section 105. When the axial flow fan 6 starts to work, the extracted outside air flows towards the lower half of the first vertical section 205, enters the Tesla valve pipe 503 through the air inlet hole 502, then flows into the dust removal device 4 through the air outlet 505, and after the internal dust particles are removed by the dust removal device 4, it is guided into the first horizontal section 208 through the third arc-shaped deflector 207 and finally flows into the room. The negative ion generator 3 provides a kind of negative oxygen ion air for the air transported into the room, which can sterilize, improve breathing, and enhance the mental state.

[0022] As Figure 3As shown, the rotating mechanism includes a transmission gear 402, a rotating component 403, and a driving gear 405. The dust removal device 4 includes a housing 401. Electrostatic film groups are respectively provided at both ends of the housing 401. The housing 401 is hollow to allow air to flow through. The size of the housing 401 is adapted to the first vertical section 205 to ensure that all the incoming air flows through the hollow part. The electrostatic film groups can adsorb fine particles in the air to achieve the purpose of purifying the air. The electrostatic film groups include a plurality of electrostatic films 404 arranged linearly. One end of the electrostatic film 404 is detachably connected to one inner side wall of the housing 401. The rotating component 403 penetrates the other symmetric inner side wall. The rotating component 403 is detachably connected to the electrostatic film 404. A transmission gear 402 is provided between the two rotating components 403. One of the rotating components 403 meshes with the driving gear 405. The driving gear 405 is fixedly connected to the output end of the first motor. The first motor is electrically connected to the control unit. The driving gear 405 is connected to the first motor as a power source. The first motor can be arranged inside the housing 401 and drives the rotating component 403 to rotate through its own rotation. When the rotating component 403 rotates, it will drive the torsion of the electrostatic film 404 so that it has different rotation angles to adapt to different air flows. The first motor, the centrifugal fan 6, and the control unit are connected. The first motor operates accordingly according to the working conditions of the centrifugal fan 6. The rotation angle of the rotating component 403 is controlled between 60° and 360°. The torsion angle of the electrostatic film 404 is consistent with the corresponding rotation angle( Figure 3 shown in it is the 300° rotation angle). The more air is inhaled by the centrifugal fan 6, the larger the rotation angle. In this embodiment, the two electrostatic film groups are arranged perpendicular to each other at both ends of the housing 401. In other embodiments, an angle of 0° - 90° can be used. The electrostatic film groups use a plurality of strip-shaped electrostatic films 404. The electrostatic films 404 are arranged in a torsion manner, so that the contact time between the air and the electrostatic region on the surface of the electrostatic film 404 is longer, increasing the adsorption amount. In addition, the torsion of the electrostatic film 404 makes the air form a vortex flow through, increasing the ventilation volume.

[0023] Such as Figure 4As shown, the rotating member 403 includes a clamping member 40312, a fixed connecting member, a movable connecting member, an upper connecting member, and a connecting tooth 4031. The upper connecting member includes a connecting plate 4032. A connecting tooth 4031 is provided at the center of the top of the connecting plate 4032. At the center and both ends of the bottom of the connecting plate 4032, a connecting sleeve is fixedly provided respectively. At the center of the top of the clamping member 40312, a fixed connecting member is fixedly provided, and movable grooves 40311 are provided at both ends. A movable connecting member is provided in each of the two movable grooves 40311. The movable connecting member and the fixed connecting member are respectively slidably connected to the corresponding connecting sleeve 4033. The bottom of the clamping member 40312 is detachably connected with an electrostatic film 404, and a pin can be used for relative fixation. The fixed connecting member includes a bottom column 4036, a limit slider 4035, and a spring 4037. The bottom column 4036 is fixedly provided at the top of the connecting plate 4032. A spring 4037 is sleeved on the bottom column 4036. A chute 4034 is provided in the connecting sleeve 4033. The limit slider 4035 is slidably connected with the chute 4034. The spring 4037 is located between the bottom of the limit slider 4035 and the bottom wall of the connecting sleeve 4033. The clamping member 40312 is made of a soft material, which can be a rubber material, etc. When the rotating member 403 rotates, since the electrostatic film 404 is twisted, the edge part will be pulled downward, and the downward amplitude of the position closer to the edge is larger. Therefore, a soft clamping material is required to ensure that both ends can move downward completely to ensure that the electrostatic film 404 will not be damaged by pulling. The fixed connecting member and the movable connecting member ensure the relative movable connection between the clamping member 40312 and the upper connecting member, preventing the electrostatic film 404 from being damaged by pulling due to external force factors. A limit ring 40310 is provided at the top of the movable groove 40311. The movable connecting member includes a bottom column 4036, a limit slider 4035, a spring 4037, a support rod 4038, and a limit block 4039. A spring 4037 is sleeved on the bottom column 4036. A chute 4034 is provided in the connecting sleeve 4033. The limit slider 4035 is slidably connected with the chute 4034. The spring 4037 is located between the bottom of the limit slider 4035 and the bottom wall of the connecting sleeve 4033. A support rod 4038 is fixedly provided at the bottom of the bottom column 4036. A limit block 4039 is fixedly provided at the bottom of the support rod 4038. The support rod 4038 has a clearance fit with the limit ring 40310, and the limit block 4039 has a clearance fit with the movable groove 40311. Since both ends of the clamping member 40312 will bend, a certain gap needs to be ensured between the support rod 4038 and the limit ring 40310 to ensure that the outer limit slider 4035 can slide in the chute 4034. When the clamping member 40312 bends downward, the support rod 4038 (and the fixedly connected part) will move downward and approach the right side of the limit ring 40310 ( Figure 4As shown in [figure number], the top of the limit block 4039 gradually disengages from the bottom of the limit ring 40310 starting from the right side, and the contact area between the two decreases. By adjusting the clearance opening between the support rod 4038 and the limit ring 40310, the bending degree at both ends of the clamping member 40312 can be adjusted.

[0024] As Figure 2 shown, the heat exchange device 5 includes a top plate 501, a bottom plate 504, and a Tesla valve through pipe 503. The top plate 501 is provided at the top of the heat exchange chamber 206, and the bottom plate 504 is provided at the bottom of the heat exchange chamber 206. The space between the top plate 501 and the bottom plate 504 is the heat exchange chamber 206. A plurality of air inlet holes 502 are evenly provided on the top plate 501, and a plurality of air outlet holes 505 are evenly provided on the bottom plate 504. The air inlet holes 502 are connected to the input end of the Tesla valve through pipe 503, and the air outlet holes 505 are connected to the output end of the Tesla valve through pipe 503. The components inside the Tesla valve through pipe 503 are as Figure 2 shown. Since the air pressure indoors is generally greater than that outdoors, it is necessary to prevent gas leakage. The Tesla valve through pipe 503 can prevent gas backflow. The Tesla valve through pipe 503 applies the principle of the Tesla valve and is an existing technology. The air heat indoors is relatively high, and the indoor and outdoor air exchange heat through the heat exchange chamber 206 to provide air with higher heat to the indoor.

[0025] As Figure 1 shown, an air outlet 204 is provided on the side wall of the first vertical section 205 near the top. An air inlet 203 is provided below the air outlet 204, and a centrifugal fan 6 is provided inside the air outlet 204. The centrifugal fan 6 draws in outside air. The air inlet 203 is arranged near the output end of the centrifugal fan 6. Here, the air flow rate is relatively large. According to Bernoulli's principle, the outside air can flow into the first vertical section 205 through the air inlet 203, increasing the air flow rate.

[0026] As Figure 1 shown, a switchable hinged door 202 is provided on the side wall of the first vertical section 205 near the bottom. A slide rail 201 is provided inside the hinged door 202, and a dust removal device 4 is provided on the slide rail 201. The slide rail 201 includes two rows of parallel slide rails 201 arranged up and down. The four slide rails 201 jointly limit the dust removal device 4 to ensure that it can only be taken out / installed through the hole of the hinged door 202. After the hinged door 202 is closed, the dust removal device 4 is fixed inside the first vertical section 205. The electrostatic film 404 in the dust removal device 4 is a consumable and needs to be replaced regularly.

[0027] In addition, both the air inlet duct 2 and the air outlet duct 1 adopt a double-layer sound insulation structure. The interlayer cavity is evacuated to reduce the impact of the noise generated during the operation of the centrifugal fan 6 and the axial flow fan group 7 on the indoor environment. At the same time, the double-layer structure can be used as a heat insulation material to prevent the heat loss of the indoor air.

[0028] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
