Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to an active ventilation door. Background Technology

[0002] Currently, most ventilation doors in the industry use a door-within-a-door design. However, this disrupts the overall door design. When the door-within-a-door is opened for ventilation, others can see the interior space from the front, compromising privacy for users. Existing ventilation doors require airflow to function properly, and the ventilated section within the door becomes thinner than the rest, reducing sound insulation, heat insulation, and thermal insulation capabilities. Furthermore, existing ventilation doors require manual opening by the user and cannot be remotely controlled. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an active ventilation door that can achieve active ventilation while also providing excellent sound insulation, heat insulation, and privacy protection for the indoor space.

[0004] An active ventilation door is provided according to an embodiment of the present invention, comprising:

[0005] The door leaf has a cavity, an air inlet channel and an air outlet channel. The cavity extends through the opposite sides of the door leaf along the thickness direction to form an open structure. The air inlet channel and the air outlet channel both extend through the door leaf along the thickness direction to form an air vent structure.

[0006] The fan assembly is provided in both the air inlet channel and the air outlet channel;

[0007] A sealing plate assembly is provided on both sides of the air inlet channel and on both sides of the air outlet channel for opening and closing the air vent structure;

[0008] A telescopic assembly is disposed within the cavity. The movable end of the telescopic assembly passes through the opening structure and is connected to the sealing plate assembly. The telescopic assembly is configured to drive the sealing plate assembly to move linearly along the thickness direction of the door leaf, thereby controlling the opening and closing of the air inlet channel or the air outlet channel.

[0009] The active ventilation door provided by this utility model has at least the following beneficial effects: When ventilation of the indoor space is required, the telescopic drive of the telescopic component causes the sealing plate component to move a certain distance away from the door leaf along the thickness direction, thereby removing the obstruction effect of the sealing plate component on the air vent structure. Through the air drive of the fan component, fresh outdoor air can enter the indoor space through the air intake channel, while stale indoor air can be discharged to the outdoor space through the exhaust channel, thus realizing the active ventilation function of the indoor space and keeping the indoor air fresh. Moreover, along the thickness direction of the door leaf, the sealing plate component can provide a certain degree of visual obstruction, preventing others from looking at the indoor situation through the air intake or exhaust channel, thereby protecting the privacy of the indoor space while actively ventilating.

[0010] When ventilation is not required, the telescopic component drives the sealing plate component to move along the thickness direction of the door leaf towards the door leaf, so that the sealing plate component abuts against the door leaf and blocks the air vent structure. This ensures that the overall thickness of the door leaf is good and effectively avoids the reduction of the door leaf's sound insulation, heat insulation and thermal insulation performance.

[0011] As a further improvement to the above technical solution, an air filter assembly is provided at the inlet end of the fan assembly.

[0012] As a further improvement to the above technical solution, the upper and lower ends of the fan assembly are provided with limiting members. At least one of the limiting members includes a plurality of spring positioning beads that can extend and retract vertically. The limiting members located at the upper and lower ends of the fan assembly together define a limiting area for engaging the air filter assembly. The air filter assembly is configured to be able to enter and exit the limiting area along the thickness direction of the door leaf.

[0013] As a further improvement to the above technical solution, the door leaf has grooves on both opposite sides along its thickness direction, and the sealing plate assembly is configured to fit and connect with the grooves so that the sealing plate assembly is flush with the door leaf; and / or,

[0014] The air inlet channel and the air outlet channel are arranged vertically opposite each other and spaced apart, and the sealing plate assembly located on the same side of the air inlet channel and the air outlet channel is integrally formed.

[0015] As a further improvement to the above technical solution, the telescopic component includes a drive source and a scissor structure. The scissor structure is configured to extend and retract along the thickness direction of the door leaf. The scissor structure is disposed between the sealing plate assembly and the drive source. The drive source is configured to drive the scissor structure to extend and retract, thereby causing the sealing plate assembly to move along the thickness direction of the door leaf.

[0016] As a further improvement to the above technical solution, the driving source includes a drive motor and a swing arm. The output end of the drive motor is fixedly connected to one end of the swing arm, and the other end of the swing arm is fixedly connected to one of the hinge rods of the scissor structure.

[0017] As a further improvement to the above technical solution, the scissor-type structures located on opposite sides of the door leaf along its thickness direction are symmetrically arranged and hinged to each other to form a telescopic mechanism. The drive motor is provided and connected to one of the hinged rods of the telescopic mechanism via the swing arm; and / or,

[0018] The drive motor is a Hall motor.

[0019] As a further improvement to the above technical solution, the active ventilation door also includes a control component, which is electrically connected to the fan assembly and the telescopic assembly respectively, and is configured to control the opening and closing of the fan assembly and the telescopic assembly.

[0020] As a further improvement to the above technical solution, the active ventilation door also includes a human body sensor, which is disposed on the door leaf and electrically connected to the control component. The human body sensor is located on the outdoor side of the door leaf. The control component is configured to control the fan assembly to close based on the detection signal from the human body sensor, and to control the telescopic assembly to drive the sealing plate assembly to block the air vent structure; and / or,

[0021] The active ventilation door also includes a control switch, which is located on the door leaf and electrically connected to the control component. The control switch is located on the indoor side of the door leaf, and the control component is configured to control the opening and closing of the fan assembly and the telescopic assembly according to the signal from the control switch.

[0022] As a further improvement to the above technical solution, the active ventilation door also includes a magnetic connector. The control component is disposed in the cavity. The magnetic connector includes a male terminal and a female terminal. One of the male terminal and the female terminal is disposed on the door leaf and electrically connected to the control component, while the other is configured to be disposed on the door frame and electrically connected to the mains power. When the door leaf is in the closed state, the male terminal and the female terminal are configured to be magnetically attracted to each other and conductive.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Reference Figures 1 to 10 This utility model provides an active ventilation door that can be applied to bedrooms, studies and other places. When the active ventilation door is closed, it can provide active ventilation. In addition, it can also provide excellent sound insulation, heat insulation and heat preservation functions and privacy protection for indoor spaces.

[0039] In this embodiment, the active ventilation door has a length direction, a width direction, and a thickness direction, wherein the length direction is assumed to be the vertical direction, the width direction is the horizontal direction, and the thickness direction is the front-back direction.

[0040] An active ventilation door includes a door leaf 100, a fan assembly 200, a sealing panel assembly, and a telescopic assembly 300.

[0041] The door leaf 100 has a cavity 110 that extends through opposite sides of the door leaf 100 along its thickness direction to form an opening structure 150. In this embodiment, opening structures 150 are provided on both the front and rear sides of the door leaf 100. It is understood that the size and shape of the cavity 110 are not limited, as long as it provides a location to accommodate the telescopic assembly 300. The size and shape of the opening structure 150 are also not limited, as long as it allows the movable end of the telescopic assembly 300 to enter and exit the opening structure 150 during telescopic movements. The number of opening structures 150 is related to the number of movable ends of the telescopic assembly 300.

[0042] The door leaf 100 is also provided with an air inlet channel 141 and an air outlet channel 142, both of which extend and penetrate along the thickness direction of the door leaf 100 to form an air vent structure. In this embodiment, air vent structures are provided on both the front and rear sides of the door leaf 100, and both the air inlet channel 141 and the air outlet channel 142 are square when viewed from the front and rear directions. It can be understood that the function of the air inlet channel 141 is to allow fresh outdoor air to flow into the indoor space, and the function of the air outlet channel 142 is to allow stale indoor air to flow to the outdoor space. The structural shape of the air inlet channel 141 and the air outlet channel 142 is not limited and can be set according to actual needs.

[0043] In addition, the door leaf 100 can be installed on the door frame via hinges. The door leaf 100 is equipped with a door handle 700 and a door lock. The door leaf 100 is opened and closed via the door handle 700, and it can be locked via the door lock after the door leaf 100 is closed. A sealing strip can be provided at the bottom of the door leaf 100 to enhance the sealing between the door leaf 100 and the door frame.

[0044] The door leaf 100 can be made of wood or metal such as stainless steel. In this embodiment, the door leaf 100 adopts a steel-wood hybrid structure. Specifically, the frame of the door leaf 100 is made of wood and has a hollow structure. The frame has a cavity that can accommodate the steel plate 130, the fan assembly 200, and the telescopic assembly 300. At least one steel plate 130 is placed inside the cavity of the frame, and there is a certain front-to-back gap between the steel plate 130 and the frame. The thickness of the frame and the steel plate 130 can be set according to the actual situation and is not specifically limited here. It is understood that the steel plate 130 can provide a fixed installation position for the fan assembly 200 and the telescopic assembly 300. The fan assembly 200 and the telescopic assembly 300 are modularly installed on the steel plate 130 in the middle of the door leaf 100 by screws, which facilitates installation, reduces the hollow size of the door leaf 100, and ensures the sound insulation and strength of the door leaf 100.

[0045] At this time, ventilation holes are provided on the steel plate 130 at the position corresponding to the fan assembly 200, so as to avoid the setting of the steel plate 130 from dividing the air inlet channel 141 or the air outlet channel 142 into two unconnected parts, thereby ensuring that indoor and outdoor ventilation can be carried out when the fan assembly 200 is working.

[0046] Both the air inlet duct 141 and the air outlet duct 142 are equipped with fan assemblies 200, which provide driving force for airflow. Understandably, when the fan assembly 200 in the air inlet duct 141 is operating, its inlet end is closer to the outdoor side of the door 100, and its outlet end is closer to the indoor side of the door 100. Therefore, outdoor air can flow into the indoor space through the air inlet duct 141. When the fan assembly 200 in the air outlet duct 142 is operating, its inlet end is closer to the indoor side of the door 100, and its outlet end is closer to the outdoor side of the door 100. Therefore, indoor air can flow out of the indoor space through the air outlet duct 142.

[0047] In some examples, the air intake duct 141 and the exhaust duct 142 are arranged at intervals along the vertical direction of the door leaf 100; for example, the air intake duct 141 is located above the exhaust duct 142. In other embodiments, the air intake duct 141 and the exhaust duct 142 are arranged at intervals along the horizontal direction of the door leaf 100; for example, the air intake duct 141 is located to the left of the exhaust duct 142. In this embodiment, the air intake duct 141 is located directly above the exhaust duct 142.

[0048] Sealing plate assemblies for opening and closing the air vent structure of the air inlet channel 141 are provided on opposite sides of the air inlet channel 141, and sealing plate assemblies for opening and closing the air vent structure of the exhaust channel 142 are also provided on opposite sides of the exhaust channel 142. It is understood that when the fan assembly 200 in the air inlet channel 141 and exhaust channel 142 is running, the sealing plate assemblies need to release their obstruction of the air vent structure, allowing the air vent structure to be open and enabling indoor and outdoor air circulation to achieve active ventilation. When ventilation is not required, the sealing plate assemblies will cover the air vent structure and abut against the surface of the door leaf 100. In this embodiment, the sealing plate assemblies can be fitted into the door leaf 100 to improve the aesthetics of the door leaf 100.

[0049] In some examples, a sealing plate assembly is provided for each air vent structure. In other examples, a sealing plate assembly is provided for two air vent structures on the same side of the air inlet duct 141 and the air outlet duct 142, which can shield the two air vent structures.

[0050] In this embodiment, as Figures 2 to 7 As shown, the air inlet channel 141 and the air outlet channel 142 are vertically opposite each other, with the air outlet channel 142 located below the air inlet channel 141. The air inlet channel 141 and the air outlet channel 142 are spaced apart. Furthermore, the sealing plate assembly located on the same side of the air inlet channel 141 and the air outlet channel 142 is integrally formed; that is, one sealing plate assembly is provided on the front and rear sides of the door leaf 100. The length of the sealing plate assembly extends vertically, and the sealing plate assembly can simultaneously block one air vent structure of the air inlet channel 141 and one air vent structure of the air outlet channel 142. This design reduces the number of telescopic components 300, lowers costs, and ensures the smooth movement of the sealing plate assembly.

[0051] like Figure 7 As shown, there are two cavities 110. The cavities 110 are used to accommodate the telescopic assembly 300. All cavities 110 are located between the air inlet channel 141 and the air outlet channel 142. A partition 120 is provided between the upper cavity 110 and the air inlet channel 141, and a partition 120 is also provided between the lower cavity 110 and the air outlet channel 142, so that the cavity 110 and the air inlet channel 141, and the cavity 110 and the air outlet channel 142 are independent of each other and not connected.

[0052] In some embodiments, the door leaf 100 has recesses on opposite sides along its thickness direction, and the sealing plate assembly is configured to fit and connect with the recesses so that the sealing plate assembly is flush with the door leaf 100. This design allows the sealing plate assembly to be embedded and tightly fitted against the door leaf 100 when the door leaf 100 is closed, making the sealing plate assembly and door leaf 100 integrated and improving the aesthetics of the door leaf 100.

[0053] Understandably, when the sealing panel assembly moves towards the door leaf 100 into the recess, the surface of the sealing panel assembly is flush with the surface of the door leaf 100, preventing the sealing panel assembly from protruding and affecting the aesthetics of the door leaf 100. In some examples, if the sealing panel assembly located on the same side of the air inlet channel 141 and the air outlet channel 142 is integrally formed, then there are two recesses, located on the front and rear sides of the door leaf 100 respectively. Each recess is simultaneously connected to the air inlet channel 141, the air outlet channel 142, and the corresponding opening structure 150. In other examples, if the sealing panel assembly located on the same side of the air inlet channel 141 and the air outlet channel 142 is not integrally formed, then there are four recesses, corresponding to the four air vent structures on the door leaf 100.

[0054] In this embodiment, as Figure 3 and Figure 4 As shown, a sealing plate assembly is provided on each of the front and rear sides of the door leaf 100. A groove is also provided on each of the front and rear sides of the door leaf 100, with the length of the groove extending vertically. Each groove connects to the air inlet channel 141, the air outlet channel 142, and the corresponding opening structure 150. Viewed vertically, the groove can be square or isosceles trapezoidal in shape.

[0055] The telescopic assembly 300 is disposed within the cavity 110 of the door leaf 100, and has a movable end capable of extending and retracting along the thickness direction of the door leaf 100. The movable end of the telescopic assembly 300 passes through the opening structure 150 of the door leaf 100 and is fixedly connected to a sealing plate assembly located outside the cavity 110. The telescopic assembly 300 is configured to drive the sealing plate assembly to move linearly along the thickness direction of the door leaf 100 to control the opening and closing of the air inlet channel 141 or the air outlet channel 142.

[0056] Understandably, the telescopic assembly 300 is used to drive the sealing panel assembly to move a certain distance linearly along the thickness direction of the door leaf 100, so that the indoor and outdoor spaces can be connected through the air inlet channel 141 and the air outlet channel 142. The telescopic assembly 300 can be a motor and linkage structure. When the telescopic assembly 300 is in operation, the sealing panel assembly can move towards the door leaf 100 and block the air vent structure, or it can move away from the door leaf 100 and open the air vent structure.

[0057] Since both the air inlet channel 141 and the air outlet channel 142 have two air vent structures, the same telescopic component 300 can be used to drive the sealing plate components located on the front and rear sides of the door leaf 100 to move simultaneously. By bringing the two sealing plate components closer to each other, the two air vent structures of the air inlet channel 141 or the air outlet channel 142 are blocked. By moving the two sealing plate components further apart, the air inlet channel 141 or the air outlet channel 142 is opened.

[0058] In this embodiment, as Figure 6 , Figure 8 and Figure 9 As shown, the telescopic assembly 300 includes a drive source 320 and a scissor structure 310. The scissor structure 310 is configured to extend and retract along the thickness direction of the door leaf 100. The scissor structure 310 is positioned between the sealing plate assembly and the drive source 320. The front and rear ends of the scissor structure 310 are connected to the sealing plate assembly and the drive source 320, respectively. The drive source 320 is configured to drive the scissor structure 310 to extend and retract, thereby moving the sealing plate assembly along the thickness direction of the door leaf 100, and controlling the sealing plate assembly to block or open the air vent structure.

[0059] It is understandable that the scissor lift structure 310 is an existing telescopic structure, generally including multiple hinge rods 315 connected by hinge shafts. The number of hinge rods 315 is selected according to actual needs. Specifically, such as... Figure 8 and Figure 9 As shown, the scissor structure 310 includes a mounting base 316, a hinge rod 315, a first mounting bracket 317, and a second mounting bracket 318. There are two hinge rods 315, which are hinged together by a hinge shaft to form a telescopic unit. Two telescopic units are provided at intervals along the left and right directions of the door leaf 100. The mounting base 316 has a first sliding groove 311 extending in the up and down direction on both the left and right sides.

[0060] For each telescopic unit, one end of one hinge rod 315 is hinged to the mounting base 316, and its hinge axis extends along the width direction of the door leaf 100. The other end of the hinge rod 315 is provided with a second slider 314. The first mounting bracket 317 is provided with a second sliding groove 313 extending in the vertical direction. The second slider 314 is adapted to the second sliding groove 313, so that the second slider 314 can slide up and down along the second sliding groove 313. The first mounting bracket 317 is fixedly connected to the sealing plate assembly. One end of the other hinge rod 315 is provided with a first slider 312, and the first slider 312 is adapted to the first sliding groove 311, so that the first slider 312 can slide up and down along the first sliding groove 311. The other end of the hinge rod 315 is hinged to a second mounting bracket 318. The second mounting bracket 318 is fixedly connected to the sealing plate assembly. The second mounting bracket 318 and the first mounting bracket 317 are arranged vertically at intervals. The hinge joint between the hinge rod 315 and the mounting base 316 is arranged vertically opposite to the first slider 312.

[0061] The shapes of the first slider 312, the second slider 314, the first groove 311, and the second groove 313 can be designed according to actual conditions, and no specific limitation is made here.

[0062] When both telescopic units extend simultaneously, the first slider 312 slides downward along the first slide groove 311, while the second slider 314 slides downward along the second slide groove 313. When both telescopic units retract simultaneously, the first slider 312 slides upward along the first slide groove 311, while the second slider 314 slides upward along the second slide groove 313. Therefore, driven by the scissor-type structure 310, the sealing plate assembly can move linearly along the front-back direction of the door leaf 100.

[0063] The drive source 320 includes a drive motor 340 and a swing arm 350. The drive motor 340 can be fixedly connected to the mounting base 316. The drive motor 340 is a reversible motor, and its output end can rotate in either the forward or reverse direction. The output end of the drive motor 340 is fixedly connected to one end of the swing arm 350, and the other end of the swing arm 350 is fixedly connected to one of the hinge rods 315 of the scissor structure 310. When the drive motor 340 is running, the swing arm 350 can swing clockwise or counterclockwise around the connection between itself and the output end of the drive motor 340, and the swing arm 350 can drive the entire scissor structure 310 to extend and retract.

[0064] In this embodiment, as Figure 8 and Figure 9 As shown, the hinge joint between the hinge rod 315 with the first mounting bracket 317 and the mounting base 316 is coaxially arranged with the connection between the swing arm 350 and the output end of the drive motor 340. The swing arm 350 is fixedly connected to one of the hinge rods 315 of the two telescopic units via U-shaped connecting blocks 360, and the two hinge rods 315 are corresponding to each other and parallel. Therefore, the two telescopic units can extend or retract simultaneously.

[0065] In some examples, a drive source 320 is provided for each scissor structure 310. In other examples, a scissor structure 310 is provided for each of the front and rear endplate assemblies of the door leaf 100, and the scissor structures 310 on the front and rear sides of the door leaf 100 are driven to extend and retract simultaneously by the same drive source 320.

[0066] In this embodiment, as Figure 8 and Figure 9As shown, the scissor structures 310 located on opposite sides of the door leaf 100 along its thickness direction are symmetrically arranged, and they are hinged to each other to form a telescopic mechanism. This telescopic mechanism can simultaneously drive the scissor structures 310 located on the front and rear sides of the door leaf 100 to extend and retract, thereby ensuring that the sealing plate assemblies located on the front and rear sides of the door leaf 100 can move synchronously. It can be understood that for the two telescopic units arranged opposite each other along the front and rear direction of the door leaf 100, the two hinge rods 315 with first mounting brackets 317 are hinged to the mounting base 316 through the same hinge axis, and the two hinge rods 315 with second mounting brackets 318 are hinged to the same first slider 312 through the same hinge axis.

[0067] Furthermore, a drive motor 340 is provided, which is mounted on the mounting base 316 with screws. The drive motor 340 is connected to one of the hinge rods 315 of the telescopic mechanism via a swing arm 350. Of course, one end of the swing arm 350 is provided with a U-shaped connecting block 360, and the two ends of the connecting block 360 are respectively fixedly connected to the two left and right corresponding hinge rods 315 of the telescopic mechanism.

[0068] like Figure 4 and Figure 6 As shown, when the two sealing plate assemblies on the same side of the door leaf 100 adopt an integrated molding design, there are two drive sources 320. Each drive source 320 simultaneously drives the scissor structure 310 located on the front and rear sides of the door leaf 100 to extend and retract, so that the sealing plate assemblies located on the front and rear sides of the door leaf 100 can move synchronously, ensuring that the sealing plate assemblies can move closer to each other or further away from each other.

[0069] like Figures 7 to 9 As shown, the mounting base 316 has a cavity for mounting the drive motor 340. The opening of the cavity allows the hinge rod 315 to extend out. After the mounting base 316 is fixedly connected to the steel plate 130 of the door leaf 100, a first cover plate 331 is provided on the mounting base 316 to improve aesthetics and protect the drive motor 340. The first cover plate 331 can cover the opening of the cavity and avoid the hinge rod 315. To facilitate the connection of the two scissor structures 310 on the mounting base 316 to the two sealing plate assemblies, the steel plate 130 of the door leaf 100 is provided with an opening for the scissor structures 310 to pass through.

[0070] Since the thickness of the door leaf 100 is limited, the telescopic component 300 in this embodiment adopts the above-described structural design. Utilizing the advantages of the scissor-type structure 310—foldability, stable telescopic movement, small footprint, and large stroke—it not only enables linear movement of the sealing panel assembly but also allows for a smaller thickness of the door leaf 100, reducing its weight, saving materials, and lowering costs. Furthermore, using the same drive source 320 to drive the scissor-type structures 310 located on both the front and rear sides of the door leaf 100 reduces the number of drive sources 320, lowering energy consumption and cost.

[0071] The drive motor 340 is a Hall motor, which uses a Hall sensor to detect the motor's operating status in real time. When the motor encounters resistance or a decrease in speed during operation, the Hall sensor detects this change and sends a signal to stop the motor, thus preventing people or objects from being trapped.

[0072] In this embodiment, the Hall motor can detect whether there are any foreign objects obstructing the movement of the sealing plate assembly driven by the scissor lift structure 310. When a foreign object is detected obstructing the movement of the sealing plate assembly, the Hall motor will stop rotating to avoid damage to the Hall motor. Moreover, as the sealing plate assembly moves towards the door leaf 100, if a person's hand is placed between the sealing plate assembly and the door leaf 100, the hand will create resistance to the sealing plate assembly. At this time, the Hall motor will stop running to prevent hand pinching and ensure people's safety.

[0073] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the fan assembly 200 has an air filter assembly 210 at its inlet. The function of the air filter assembly 210 is to filter impurities in the air flowing towards the fan assembly 200, preventing dust accumulation in the fan assembly 200. The air filter assembly 210 can be a filter screen, filter cotton, or a high-efficiency air filter, etc., and has a good interception effect, capable of filtering dust, hair, fibers, etc. The air filter assembly 210 can be fixedly connected to the fan assembly 200 or to the door leaf 100.

[0074] Furthermore, such as Figure 7 and Figure 10 As shown, the air filter assembly 210 is detachable, making it easy to remove and replace.

[0075] In this embodiment, the fan assembly 200 is provided with limiting members at both its upper and lower ends. The limiting members at both ends of the fan assembly 200 can jointly define a limiting area. The limiting area is used to engage the air filter assembly 210. At least one limiting member includes a plurality of spring positioning beads 203 that can extend and retract vertically. The air filter assembly 210 is configured to move in and out of the limiting area along the thickness direction of the door leaf 100.

[0076] Specifically, the fan assembly 200 includes a fan 201 and a bracket 202, on which at least one fan 201 can be mounted. A limiting frame 204 is provided at the upper end of the bracket 202, and a plurality of spring positioning beads 203 arranged at intervals along the left-right direction are provided at the lower end of the bracket 202. The limiting frame 204 has a downward-facing limiting groove. The spring positioning beads 203 and the limiting frame 204 are arranged opposite to each other. Under pressure, the balls in the spring positioning beads 203 move downwards, and under the elastic force of the spring, the balls can move upwards and return to their original position.

[0077] Understandably, people can place the air filter assembly 210 in the limiting area along the front and back direction of the door leaf 100. First, the upper end of the air filter assembly 210 is inserted into the limiting groove of the limiting frame 204. Then, the lower end of the air filter assembly 210 can be pressed to drive the lower end of the air filter assembly 210 to move towards the bracket 202. The lower end of the air filter assembly 210 will squeeze the spring positioning bead 203 so that the air filter assembly 210 is completely located in the limiting area, so that the air filter assembly 210 is in a stable fixed state, thereby realizing the detachable connection of the air filter assembly 210 to the fan assembly 200. At this time, the upper end of the air filter assembly 210 will be limited by the limiting frame 204, and the lower end of the air filter assembly 210 will be limited by the spring positioning bead 203.

[0078] When disassembling the air filter assembly 210, the lower end of the air filter assembly 210 is driven to swing outward. At this time, the lower end of the air filter assembly 210 will squeeze the spring positioning ball 203, allowing the lower end of the air filter assembly 210 to break free from the limiting effect of the spring positioning ball 203. Immediately afterwards, the upper end of the air filter assembly 210 is driven to disengage from the limiting groove of the limiting frame 204, so as to facilitate subsequent cleaning or replacement of the air filter assembly 210. When disassembling and assembling the air filter assembly 210, the telescopic component 300 needs to drive the sealing plate assembly to move away from the door leaf 100 to create a certain space, making it convenient for people to disassemble and assemble the air filter assembly 210 in the limiting area.

[0079] With the above structural design, the air filter assembly 210 can be quickly disassembled and assembled with one hand without the need for auxiliary tools such as screwdrivers, reducing the difficulty of disassembling and assembling the air filter assembly 210. In addition, the maximum front-to-back distance between the sealing plate assembly and the door leaf 100 can be designed to be smaller.

[0080] Of course, it is possible to interchange the positions of the spring positioning ball 203 and the limiting frame 204. Furthermore, it is possible that in other embodiments, the limiting members located at both ends of the fan assembly 200 may employ multiple spring positioning balls 203.

[0081] In some embodiments, such as Figure 7 As shown, each panel assembly includes a fixing frame 430 and a decorative panel 410. The fixing frame 430 is fixedly connected to the decorative panel 410 and is located between the decorative panel 410 and the door leaf 100. The fixing frame 430 is made of metal, and the decorative panel 410 can be made of metal or wood.

[0082] In this embodiment, the fixing frame 430 is made of galvanized material, which gives it strong corrosion resistance and makes it less prone to rusting. The decorative panel 410 is made of aluminum plate. The surface of aluminum plate is relatively smooth, making it difficult for dirt, dust, and other impurities to adhere, and it is easy to clean. Compared with other materials with rough surfaces, aluminum plate has low cleaning and maintenance costs and can maintain a good appearance for a long time. It can be understood that the combination of the fixing frame 430 and the decorative panel 410 enables the door leaf 100 to have good sound insulation, heat insulation, and thermal insulation effects when the telescopic component 300 drives the sealing plate component to block the air vent structure. In addition, the surface of the decorative panel 410 can be patterned to match the door leaf 100 and improve the overall aesthetics of the door leaf 100.

[0083] Furthermore, such as Figure 1 , Figures 3 to 7 As shown, each panel assembly also includes a decorative element 420, which is fixedly connected to the decorative panel 410. The decorative element 420 enhances the decorative effect of the door panel 100. In this embodiment, the decorative element 420 is trumpet-shaped and fixedly installed at the lower end of the decorative panel 410, which is located between the decorative element 420 and the fixed frame 430.

[0084] In some embodiments, such as Figure 7 As shown, the active ventilation door also includes a control component 510. The control component 510 is electrically connected to the fan assembly 200 and the telescopic assembly 300 via wiring, and is configured to control the opening and closing of the fan assembly 200 and the telescopic assembly 300.

[0085] It is understood that the control component 510 can be a 51 microcontroller, a PLC controller, or an ARM architecture processor, etc. The control component 510 can be installed inside the cavity 110 of the door leaf 100, or on the door frame or other locations. The control component 510 can be wirelessly connected to a remote control, a mobile app, etc., via WiFi or Bluetooth, allowing users to remotely operate the fan assembly 200 and the telescopic assembly 300 to start or stop. Furthermore, the control component 510 can also be connected to a switch assembly via a wire; the switch assembly can be a control button or a touchscreen. The switch assembly can be installed on the door leaf 100 or on the wall.

[0086] In this embodiment, the control component 510 is fixedly connected to the steel plate 130 of the door leaf 100. In order to protect the control component 510, a second cover plate 332 is provided. The second cover plate 332 can be connected to the steel plate 130 and form a protective cavity. The control component 510 is located in the protective cavity.

[0087] Furthermore, such as Figures 1 to 7 As shown, the active ventilation door also includes a human body sensor 530 and a control switch 520. Both the human body sensor 530 and the control switch 520 are located on the door leaf 100 and are electrically connected to the control assembly 510. The human body sensor 530 is located on the outdoor side of the door leaf 100, and the control switch 520 is located on the indoor side of the door leaf 100. The control assembly 510 is configured to control the fan assembly 200 to close based on the detection signal from the human body sensor 530, and to control the telescopic assembly 300 to drive the sealing plate assembly to block the air vent structure. Furthermore, the control assembly 510 is also configured to control the opening and closing of the fan assembly 200 and the telescopic assembly 300 based on the signal from the control switch 520.

[0088] Understandably, the human body sensor 530 can be an infrared human body sensor or radar. Located on the outdoor side of the door 100, the human body sensor 530 can detect whether someone is passing by outside. If the fan assembly 200 is on, and the sealing panel assembly is about to open or has already opened the vent structure under the drive of the telescopic assembly 300, when the human body sensor 530 detects someone passing by, it will generate a detection signal and send it to the control assembly 510. The control assembly 510 will then send a shutdown command to the telescopic assembly 300 and the fan assembly 200, causing the fan assembly 200 to stop operating. Simultaneously, the telescopic assembly 300 will drive the sealing panel assembly to move and block the vent structure. This prevents people outside from seeing into the room, protecting user privacy, and also ensures that the door 100 has good sound insulation performance.

[0089] Once people outside have moved away, under the control command of the control component 510, the telescopic component 300 will drive the sealing plate component to move and automatically open the air vent structure, so that both the air intake channel 141 and the air exhaust channel 142 are connected to the indoor and outdoor spaces. At the same time, the fan component 200 will start, ventilating the indoor space through the air intake channel 141 and the air exhaust channel 142, thereby realizing the ventilation function being turned off when people approach to protect privacy, and automatically turning on the ventilation function after people have moved away.

[0090] The control switch 520 is located on the indoor side of the door leaf 100. People can manually operate the control switch 520 to control the working status of the fan assembly 200 and the telescopic assembly 300.

[0091] In this embodiment, the control switch 520 is installed on the decorative piece 420 on the interior side of the door leaf 100. The control switch 520 is installed on the decorative piece 420, making the control switch 520 a conspicuous place so that the user can quickly find the location of the control switch 520. The user can open and close the telescopic component 300 and the fan component 200 by touching the control switch 520.

[0092] A human body sensor 530 is installed on the decorative piece 420 on the exterior side of the door leaf 100. The human body sensor 530 is an infrared human body sensor. The infrared human body sensor is highly sensitive to infrared radiation emitted by the human body, enabling accurate detection of human presence even under relatively low temperature differences, achieving high-precision human body sensing and monitoring. By sensing infrared radiation of a specific wavelength emitted by the human body and converting it into an electrical signal for analysis and processing, the sensor effectively filters out other interference signals, reducing false alarms and achieving high accuracy. Furthermore, its response time is extremely short; once a human body enters the detection range, the infrared human body sensor can respond rapidly, ensuring that the control component 510 can quickly send a shutdown control command to the fan assembly 200 and the sealing plate assembly, thus protecting the user's indoor privacy.

[0093] Of course, it is possible that the human body sensor 530 and the control switch 520 are located in other positions on the door leaf 100.

[0094] Furthermore, the active ventilation door also includes a magnetic connector 600.

[0095] The control component 510 is located inside the cavity 110 of the door leaf 100. The control component 510 can be positioned between the two telescopic components 300. The control component 510 is electrically connected to all the fan components 200, all the telescopic components 300, the human body sensor 530, and the control switch 520 via wires. The control component 510 can be fixedly installed on the steel plate 130 of the door leaf 100.

[0096] The magnetic connector 600 includes a male terminal and a female terminal. One of the male and female terminals is located on the door leaf 100 and is electrically connected to the control component 510 via wiring. The other terminal is configured to be located on the door frame and is directly or indirectly electrically connected to the mains power via wiring. Furthermore, when the door leaf 100 is closed, the male and female terminals are configured to be magnetically attracted and conductive, thus enabling the control component 510 to operate and provide power to the fan assembly 200, the telescopic assembly 300, the human body sensor 530, and the control switch 520.

[0097] Understandably, the male and female terminals are installed separately, on corresponding positions on the door leaf 100 and door frame, respectively. Specifically, the magnetic connector 600 can be located on the hinged side of the door leaf 100. When the door leaf 100 is open, the male and female terminals are separated. At this time, the control component 510 is de-energized, and therefore, the telescopic component 300, fan component 200, human body sensor 530, and control switch 520 cannot be powered on.

[0098] The magnetic connector 600 achieves circuit connection through contact, eliminating the need for exposed wires. Compared to traditional wiring methods, it is simpler, faster, and easier to install and maintain. It prevents damage such as squeezing and wear to the wires passing between the door leaf 100 and the door frame during the opening and closing of the door leaf 100, thus extending the service life of the wiring. It also makes the wiring arrangement between the door leaf 100 and the door frame neater and more aesthetically pleasing, avoiding messy wiring that affects the overall appearance. Furthermore, it can control the power cut-off of the fan assembly 200, human body sensor 530, control switch 520, telescopic assembly 300, and control assembly 510 when the door leaf 100 is open, thereby saving energy.

[0099] In this embodiment, the magnetic connector 600 is a four-pin contact cable with four independent conductive contacts, capable of simultaneously transmitting four different electrical signals or powering four different device components. Compared to two-pin or three-pin contact cables, it can meet the connection needs of more functional devices. When the door 100 is closed, the conductive contacts on the male and female terminals will make contact and conduct electricity. At this time, current can flow through the four-pin contact cable to the control component 510, fan assembly 200, telescopic assembly 300, human body sensor 530, and control switch 520, enabling them to operate normally under power.

[0100] When using the active ventilation door provided in this embodiment of the present invention, when ventilation of the indoor space is required, the telescopic component 300 is activated. With the driving action of the telescopic component 300, the sealing plate component can move a certain distance away from the door leaf 100 along the thickness direction of the door leaf 100, so as to release the blocking effect of the sealing plate component on the air vent structure, so that the air vent structure is in the open state, ensuring that the air inlet channel 141 and the air outlet channel 142 are connected to the indoor space and the outdoor space. By activating the fan component 200, the air driving action of the fan component 200 can cause fresh outdoor air to enter the indoor space through the air inlet channel 141, while the stale indoor air can be discharged to the outdoor space through the air outlet channel 142, thereby realizing the active ventilation function of the indoor space and keeping the indoor air fresh.

[0101] When active ventilation is in operation, the door 100 is closed. Furthermore, along the thickness of the door 100, the sealing panel assembly can provide a certain degree of visual obstruction, preventing others from easily viewing the interior through the air intake channel 141 or the exhaust channel 142, thereby protecting the privacy of the interior space when the active ventilation function is activated.

[0102] When ventilation is not required, the telescopic component 300 drives the sealing plate component to move along the thickness direction of the door leaf 100 towards the door leaf 100, so that the sealing plate component abuts against the door leaf 100 and blocks the air vent structure, keeping the air vent structure in a closed state. This ensures that the air inlet channel 141 and the air outlet channel 142 are in a sealed state, thus ensuring the overall thickness of the door leaf 100 and ensuring that the door leaf 100 has excellent sound insulation, heat insulation and thermal insulation effects.
