[0005] Furthermore, the rotating mechanism includes transmission gears, rotating components, and drive gears. The dust removal device includes a housing, with electrostatic film groups at both ends of the housing. Each electrostatic film group includes multiple linearly arranged electrostatic films. One end of each electrostatic film is detachably connected to one inner sidewall of the housing. The rotating component passes through another symmetrical inner sidewall and is detachably connected to the electrostatic film. The transmission gears are provided between the two rotating components, with one rotating component meshing with the drive gears. The drive gears are fixedly connected to the output end of a motor, and the motor is electrically connected to a control unit.

[0006] Furthermore, the rotating component includes a clamping member, a fixed connecting member, a movable connecting member, an upper connecting member, and connecting teeth. The upper connecting member includes a connecting plate with the connecting teeth at the top center. A connecting sleeve is fixedly provided at the bottom center and both ends of the connecting plate. The clamping member has a fixed connecting member fixedly provided at the top center and movable grooves at both ends. A movable connecting member is provided in each of the two movable grooves. The movable connecting member and the fixed connecting member are slidably connected to the corresponding connecting sleeves. The electrostatic film is detachably connected to the bottom of the clamping member.

[0007] Furthermore, the fixed connecting component includes a base post, a limiting slider, and a spring. The base post is fixedly disposed on the top of the connecting plate, and the spring is sleeved on the base post. The connecting sleeve has a sliding groove, and the limiting slider is slidably connected to the sliding groove.

The support rod is clearance-fitted with the limiting ring, and the limiting block is clearance-fitted with the movable groove.

[0009] Furthermore, the heat exchange device includes a top plate, a bottom plate, and a Tesla valve through pipe. The top plate is provided at the top of the heat exchange chamber, and the bottom plate is provided at the bottom of the heat exchange chamber. The top plate is provided with a plurality of air inlets evenly, and the bottom plate is provided with a plurality of air outlets evenly. The air inlets are connected to the input end of the Tesla valve through pipe, and the air outlets are connected to the output end of the Tesla valve through pipe.

[0010] Furthermore, the air outlet duct also includes a grille and a third horizontal section, the grille being provided on the bottom sidewall of the second vertical section, and the third horizontal section connecting to the top of the second vertical section; the air inlet duct also includes a first horizontal section, the first horizontal section connecting to the bottom of the first vertical section; a negative ion generator is fixedly provided in the first horizontal section, and an axial flow fan unit is fixedly provided in the third horizontal section, the negative ion generator and the axial flow fan unit being electrically connected to a control unit.

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

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1-5As shown, the periscope-style ventilator is installed at the window position and fixed to 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. The grille 101 is provided on the side wall of the second vertical section 102 near the interior. The third horizontal section 105 connects to the second vertical section 102. The top of the vertical section 102; the air inlet duct 2 also includes a first horizontal section 208, which connects to the bottom of the first vertical section 205; the third horizontal section 105 is located at the top of the first vertical section 205, and the second vertical section 102 is located at the top of the first horizontal section 208. A centrifugal fan 6, a heat exchange device 5 (coinciding with the heat exchange chamber 206), and a dust removal device 4 are arranged sequentially from top to bottom within the first horizontal section 208. The outlet of the centrifugal fan 6 is parallel to the first horizontal section 208. A negative ion generator 3 is fixedly installed within the first horizontal section 208, and an axial flow fan unit 7 is fixedly installed within the third horizontal section 105. The axial flow fan unit 7 is arranged parallel to the third horizontal section 105. The negative ion generator 3 and the axial flow fan unit 7 are electrically connected to a control unit, which controls their operation. In another embodiment, a temperature detection and heating device is also provided within the first horizontal section 208 to further heat the intake air to achieve a suitable temperature. The control unit can be an infrared remote control, a mobile phone, etc. When the axial flow fan unit 7 is working, indoor air enters the lower half of the second vertical section 102 through the grille 101, is guided by the first arc-shaped guide plate 102 into the heat exchange chamber 206 to exchange heat with the air in the Tesla valve pipe 503, and then is guided back into the upper half of the second vertical section 102 through the second arc-shaped guide plate 104 before being discharged to the outside through the third horizontal section 105. When the centrifugal fan 6 starts working, the drawn outside air flows into the lower half of the first vertical section 205, enters the Tesla valve pipe 503 through the air inlet 502, and then flows into the dust removal device 4 through the air outlet 505. After the dust removal device 4 removes the internal micro-dust particles, it is guided by the third arc-shaped guide plate 207 into the first horizontal section 208 before finally flowing into the room. The negative ion generator 3 provides negative oxygen ion air to the air supplied into the room, which can sterilize, disinfect, improve breathing, and enhance mental state.

[0022] like Figure 3As shown, the rotating mechanism includes a transmission gear 402, a rotating component 403, and a drive gear 405. The dust removal device 4 includes a housing 401, with electrostatic film groups at both ends of the housing 401. The housing 401 is hollow to allow air circulation. The size of the housing 401 is adapted to the first vertical section 205 to ensure that all 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 multiple linearly arranged electrostatic films 404. One end of the electrostatic film 404 is detachably connected to one of the inner sidewalls of the housing 401. The rotating component 403 passes through another symmetrical inner sidewall. 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 drive gear 405. The drive gear 405 is fixedly connected to the output end of the motor. The motor is electrically connected to the control unit. The drive gear 405 is connected to a motor 1 as a power source. The motor 1 can be installed inside the housing 401. Its rotation drives the rotating component 403 to rotate. The rotation of the rotating component 403 causes the electrostatic film 404 to twist, resulting in different rotation angles to accommodate different airflow rates. The motor 1, centrifugal fan 6, and control unit are connected. The motor 1 operates according to the working conditions of the centrifugal fan 6. The rotation angle of the rotating component 403 is controlled between 60° and 360°, and the twist angle of the electrostatic film 404 corresponds to the rotation angle. Figure 3 The image shows a 300° rotation angle. The more air the centrifugal fan 6 draws in, the larger the rotation angle. In this embodiment, the two sets of electrostatic film groups are arranged perpendicularly at both ends of the outer casing 401. In other embodiments, they can be arranged at angles of 0°-90°. The electrostatic film group uses multiple elongated electrostatic films 404, which are twisted to increase the contact time between the air and the electrostatic area on the surface of the electrostatic film 404, thereby increasing the adsorption capacity. In addition, the twisted electrostatic film 404 causes the air to form vortices, increasing the ventilation volume.

[0023] like Figure 4As shown, the rotating component 403 includes a clamping member 40312, a fixed connector, a movable connector, an upper connector, and a connecting tooth 4031. The upper connector includes a connecting plate 4032, with a connecting tooth 4031 at the top center of the connecting plate 4032. A connecting sleeve is fixedly provided at the bottom center and both ends of the connecting plate 4032. A fixed connector is fixedly provided at the top center of the clamping member 40312, and movable grooves 40311 are provided at both ends. A movable connector is provided in each of the two movable grooves 40311. The movable connector and the fixed connector are slidably connected to the corresponding connecting sleeves 4033. An electrostatic film 404 is detachably connected to the bottom of the clamping member 40312, which can be fixed relative to each other by using pins. The fixed connector includes a base post 4036, a limiting slider 4035, and a spring 4037. The base post 4036 is fixedly mounted on the top of the connecting plate 4032. The spring 4037 is sleeved on the base post 4036. A groove 4034 is provided inside the connecting sleeve 4033. The limiting slider 4035 is slidably connected to the groove 4034. The spring 4037 is located between the bottom of the limiting slider 4035 and the bottom wall of the connecting sleeve 4033. The clamping member 40312 is made of a soft material, such as rubber. When the rotating component 403 rotates, the electrostatic film 404 is twisted, so the edge part will be pulled downward. The downward pull is greater towards the edge. Therefore, a soft clamping material is needed to ensure that both ends can be pulled downward completely, ensuring that the electrostatic film 404 will not be pulled and damaged. The fixed connector and the movable connector ensure a relatively movable connection between the clamping member 40312 and the upper connector, preventing the electrostatic film 404 from being pulled and damaged by external forces. The top of the movable groove 40311 is provided with a limiting ring 40310. The movable connecting parts include a bottom column 4036, a limiting slider 4035 and a spring 4037, a support rod 4038 and a limiting block 4039. The spring 4037 is sleeved on the bottom column 4036. The connecting sleeve 4033 is provided with a sliding groove 4034. The limiting slider 4035 is slidably connected to the sliding groove 4034. The spring 4037 is located between the bottom of the limiting slider 4035 and the bottom wall of the connecting sleeve 4033. The support rod 4038 is fixedly provided at the bottom of the bottom column 4036. The limiting block 4039 is fixedly provided at the bottom of the support rod 4038. The support rod 4038 is clearance-fitted with the limiting ring 40310, and the limiting block 4039 is clearance-fitted with the movable groove 40311. Because the clamping member 40312 bends at both ends, a certain gap must be maintained between the support rod 4038 and the limiting ring 40310 to ensure that the outer limiting slider 4035 can slide within the groove 4034. When the clamping member 40312 bends downward, the support rod 4038 (and the fixed connection part) will move downward and approach the right side of the limiting ring 40310. Figure 4As shown in the figure, the top of the limiting block 4039 gradually separates from the bottom of the limiting ring 40310 from the right side, and the contact area between the two is reduced. The degree of bending at both ends of the clamping member 40312 can be adjusted by adjusting the gap between the support rod 4038 and the limiting ring 40310.

[0024] like Figure 2 As 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 located at the top of the heat exchange chamber 206, and the bottom plate 504 is located at the bottom of the heat exchange chamber 206. The space between the top plate 501 and the bottom plate 504 constitutes the heat exchange chamber 206. Multiple air inlets 502 are evenly distributed on the top plate 501, and multiple air outlets 505 are evenly distributed on the bottom plate 504. The air inlets 502 connect to the input end of the Tesla valve through-pipe 503, and the air outlets 505 connect to the output end of the Tesla valve through-pipe 503. The internal components of the Tesla valve through-pipe 503 are as follows... Figure 2 As shown, since the indoor air pressure is generally higher than the outdoor air pressure, it is necessary to prevent gas leakage. The Tesla valve through-pipe 503 prevents backflow of gas. The Tesla valve through-pipe 503 utilizes the principle of a Tesla valve and is existing technology. The indoor air has a relatively higher heat content, and the indoor and outdoor air exchange heat through the heat exchange chamber 206 to provide even hotter air to the indoor environment.

[0025] like Figure 1 As shown, an air vent 204 is provided on the side wall near the top of the first vertical section 205, and an air inlet 203 is provided at the lower part of the air vent 204. A centrifugal fan 6 is installed inside the air vent 204. The centrifugal fan 6 draws in outside air. The air inlet 203 is located near the output end of the centrifugal fan 6, where the air velocity is relatively high. According to Bernoulli's principle, outside air can flow into the first vertical section 205 through the air inlet 203, increasing the airflow.

[0026] like Figure 1 As shown, a hinged door 202 is provided on the side wall near the bottom of the first vertical section 205. A slide rail 201 is provided inside the hinged door 202, and a dust removal device 4 is mounted on the slide rail 201. The slide rail 201 includes two parallel rows of slide rails 201, and the four slide rails 201 together limit the dust removal device 4, ensuring that it can only be removed / installed through the opening in 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 periodically.

[0027] In addition, both the air inlet duct 2 and the air outlet duct 1 adopt a double-layer sound insulation structure. The vacuum in the interlayer cavity reduces the impact of noise generated by the centrifugal fan 6 and the axial flow fan unit 7 on the indoor environment. At the same time, the double-layer structure can also serve as a heat insulation material to prevent heat loss from the indoor air.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
