[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. **Advantages of Ventilation Function:** The louvered design of this wooden door allows for flexible adjustment of ventilation volume according to user needs. By manually adjusting the louver angle, the ventilation volume can be precisely controlled between 0% and 100%. For example, in humid weather, the louver angle can be increased to enhance ventilation and quickly dry the indoor air; conversely, to maintain indoor temperature or privacy, the louver angle can be decreased to reduce ventilation. 2. **Improved Indoor Air Quality:** Adjustable ventilation helps improve indoor air quality. Proper ventilation effectively removes stale air, such as carbon dioxide, odors, and moisture, while introducing fresh air. This is crucial for the health of residents, especially in enclosed spaces. For example, installing this type of wooden door in the kitchen allows for timely removal of cooking fumes and odors during cooking, keeping the indoor air fresh. 3. **Aesthetics and Decorative Features:** The louvered design adds a unique aesthetic to the wooden door, blending seamlessly with various decorating styles. Wooden louvers offer a natural and warm texture, suitable for country and classical Chinese styles; aluminum alloy louvers, with their modern feel and metallic sheen, complement modern minimalist and industrial styles; PVC plastic louvers come in a variety of colors to meet different color matching needs and are suitable for various interior decoration styles. These wooden doors are not only practical ventilation facilities but also important elements of interior design. The arrangement of the louvers creates rich visual layers. When light shines through the louvers, it produces light and shadow effects, which change with the angle of the louvers, adding a dynamic beauty to the interior space. This interplay of light and shadow can create a warm, comfortable, or stylish atmosphere, enhancing the overall artistic feel of the space.

[0017] 2. Privacy Protection Function: Adjustable privacy levels allow for effective control of the visual transparency between indoors and outdoors by adjusting the angle of the louvers, thus achieving privacy protection. When the louvers are fully closed, the interior is completely blocked, protecting privacy. When the louver angle is adjusted appropriately, it allows selective visibility while maintaining a certain level of ventilation. For example, in spaces requiring privacy, such as bedrooms or bathrooms, users can flexibly adjust the louver angle according to their needs, enjoying ventilation while preventing others from peeping in. Durability and Ease of Maintenance: Durable materials and the choice of materials for the door frame and core ensure the sturdiness and durability of the wooden door. Solid wood door frames and cores have excellent resistance to pressure and deformation; aluminum alloy louvers have excellent corrosion resistance, enabling long-term use under various environmental conditions. These materials have a long service life, reducing the frequency of door replacement and lowering operating costs. Easy Cleaning and Maintenance: The louvered design makes cleaning relatively easy. Compared to traditional solid wood doors, the gaps between the louvers facilitate the cleaning of dust and dirt. You can use a feather duster or a small cleaning brush to easily clean the surface of the louvers. For heavily soiled areas, you can also disassemble the louvers for cleaning. Meanwhile, other parts of the door can be maintained using regular cleaning methods to keep the wooden door clean and beautiful. Attached Figure Description

[0026] Preferably, the main body mechanism 1 further includes a hinge 104 and a door panel 105. The hinge 104 is fixedly connected between the door body 101 and the door frame 102, and the door panel 105 is fixedly installed on the surface of the door body 101.

[0027] Preferably, the main body 1 further includes a handle 106 and a lock 107. The handle 106 is fixedly installed on the surface of the door body 101, and the lock 107 is fixedly installed at the bottom of the handle 106.

[0028] Preferably, the main body mechanism 1 further includes a slot 108 and a bolt 109. A plurality of slots 108 are fixedly installed on the surface of the door frame 102, and bolts 109 are fixedly installed on the slots 108.

[0029] Preferably, the louver mechanism 2 further includes a fixing groove 204 and a bushing 205. The fixing groove 204 is fixedly installed in the center of the door body 101, the bushing 205 is fixedly installed in the fixing groove 204, and the louver shaft 203 is fixedly connected to the bushing 205.

[0030] Preferably, the louver mechanism 2 further includes a connecting rod 206 and a knob 207. Several connecting rods 206 are fixedly installed inside the louver body 201, and a knob 207 is fixedly installed at the front end of the louver body 201.

[0031] Working Principle: The door body 101 structure and the door frame 102 are described below. The door frame 102 is made of solid wood or a composite wood material. Solid wood door frames 102 are high-quality, sturdy, and durable, typically using hardwoods such as oak or walnut. These woods have high density and excellent compressive and bending strength, providing a stable support structure for the door body 101. Composite wood door frames 102 are made of various types of wood or wood combined with other materials, combining economy and good performance. Their internal structure may be a solid wood frame covered with MDF or plywood, effectively preventing deformation. The width of the door frame 102 is typically between 6 and 10 centimeters, and its thickness between 3 and 5 centimeters. These dimensions ensure a secure installation and a tight fit with the door body 101.

[0032] The door frame 102 is fixed to the wall using expansion bolts 109 or wooden wedges. Expansion bolts 109 are used for concrete walls; they utilize the expansion principle of the bolt 109. When the nut is tightened, the metal sleeve of the bolt 109 expands, tightly locking into the wall and providing strong fixing force. Wooden wedges are suitable for brick or wooden walls. The wedges are driven into pre-drilled holes in the wall, and then the door frame 102 is nailed to the wedge, firmly fixing the door frame 102 to the wall. The door frame 102 and the door body 101 are connected by hinges 104. There are typically 2 or 3 hinges, mostly made of stainless steel or copper alloy, with a thickness between 3 and 5 mm. These hinges are installed on the door frame 102 and the door body 101 with screws, capable of bearing the weight of the door body 101 and ensuring its flexible opening and closing.

[0033] The door core 103, as a key component of the door body 101, is filled with honeycomb paper, solid wood strips, or sound and heat insulation materials. Honeycomb paper is an economical filling material with a honeycomb structure that provides some support while reducing the weight of the door body 101. Solid wood strip-filled door cores are more robust and have a better texture; gaps between the strips allow for ventilation. For door cores 103 with a focus on sound and heat insulation, materials such as rock wool or polystyrene foam may be used, as these materials have low thermal conductivity and good sound insulation properties. The thickness of the door core 103 is generally between 3 and 5 centimeters, a thickness that ensures both the strength of the door body 101 and the functionality of the filling materials.

[0034] The door core 103 is joined to the door frame 102 using either mortise and tenon joints or glue. Mortise and tenon joints are a traditional woodworking method. A tenon is made on the edge of the door core 103, and a mortise is drilled in the door frame 102. The tenon is inserted into the mortise, resulting in a tight and aesthetically pleasing connection. Glue bonding involves applying wood glue to the contact surfaces of the door core 103 and door frame 102, then clamping them together to ensure a firm bond. Once the glue cures, a strong connection is formed. If the door core 103 is connected to the door panel, it is done in a similar way to ensure the overall structural integrity of the door 101.

[0035] Regarding door panel 105, its materials and design can be solid wood veneer, plywood, or engineered wood panels. Solid wood veneer features natural wood grain, is aesthetically pleasing, and is typically 3-6 mm thick. Plywood is made by gluing together multiple layers of thin wood veneers, offering good strength and stability; it usually consists of 3-5 layers, each 1-3 mm thick. Engineered wood panels, such as medium-density fiberboard (MDF) or particleboard, are less expensive, and their surfaces can be veneered or painted to mimic wood grain. Door panel 105 can undergo various decorative treatments, such as carving, painting, and wood veneer, to meet different interior design needs.

[0036] The connection methods between the door panel 105 and the door core 103 are mainly adhesive bonding and nailing. Adhesive bonding involves applying glue to the contact surfaces of the door panel 105 and the door core 103, then applying pressure to bond them together. This method results in a smooth surface for the door panel 105, free of nail holes and other defects. Nailing involves using nails or screws to fix the door panel 105 to the door core 103. The spacing between the nails or screws is generally between 10 and 20 centimeters, ensuring even distribution to firmly fix the door panel 105 to the door core 103.

[0037] The louver structure, materials, and specifications vary. Louver materials include wood, aluminum alloy, and PVC plastic. Wooden louvers offer a warm feel and coordinate with the overall style of wooden doors. They are typically made of the same or similar wood as the door frame, such as pine or cedar, and are between 0.5 and 1 cm thick. Aluminum alloy louvers offer good corrosion resistance and strength. Their surface can be anodized or spray-coated, resulting in different colors and glosses. The thickness of these louvers ranges from 0.3 to 0.8 cm. PVC plastic louvers are inexpensive, lightweight, and have good waterproof properties. They are between 0.4 and 0.9 cm thick and come in a variety of colors to suit different needs.

[0038] The dimensions of louvers vary. The width of louvers is generally between 3 and 8 centimeters, while the length depends on the door height for ease of installation and adjustment. The spacing between the louvers is also an important parameter, typically between 0.5 and 2 centimeters. This spacing determines the ventilation volume and uniformity, and also affects the visual appearance of the door.

[0039] The louver connection and adjustment mechanism involves connecting the louvers to the door body 101 via a louver shaft 203. The louver shaft 203 is typically made of metal and has a diameter between 0.3 and 0.6 cm. Both ends of the louver have holes; inserting the louver shaft 203 into these holes allows the louvers to rotate around the shaft. There are several ways to fix the louver shaft 203 to the door body 101. A bushing 205 or a bearing seat is installed on the door body 101. After the louver shaft 203 is inserted into the bushing 205 or bearing seat, it is secured with screws or clips, ensuring the louvers are stably installed on the door body 101 and can rotate freely.

[0040] The adjustment of the louvers can be achieved manually. Manual adjustment is achieved by controlling the angle of the louvers using knob 207. Knob 207 is installed on the door body 101 and is connected to the louver shaft 203 via a connecting rod 206 mechanism. When knob 207 is turned, the connecting rod 206 mechanism drives the louver shaft 203 to rotate, thereby changing the angle of the louvers.

[0041] The ventilation volume adjustment structure and its relationship to the angle of the louvers are closely related. Ventilation volume is maximized when the louvers are fully open. According to fluid dynamics principles, air can flow smoothly through the gaps between the louvers, and the ventilation area is approximately the product of the louver spacing and the louver length. As the louver angle gradually decreases and approaches the door plane, the ventilation volume gradually decreases. When the louvers are completely closed and parallel to the door plane, the ventilation volume is almost zero. For example, on a wooden door with a louver spacing of 1 cm and a length of 2 meters, the ventilation area is 0.01 square meters when the louvers are fully open. Assuming the louver thickness is ignored, the ventilation effect is optimal. When the louver angle is adjusted to a 45-degree angle with the door plane, the ventilation area decreases, and the ventilation volume decreases accordingly.

[0042] The ventilation volume control range can be adjusted between 0% and 100% by adjusting the angle of the louvers. The actual ventilation volume control range is also affected by factors such as louver spacing, length, and the overall size of the door. Generally, while ensuring the basic functions of the door, such as aesthetics and security, the effective ventilation volume control range can be between 20% and 80%. For example, in environments where ventilation requirements are not particularly high, the ventilation volume can be adjusted to a lower level, such as around 30%, which can meet certain ventilation needs while maintaining indoor privacy; while in situations requiring rapid ventilation, the ventilation volume can be adjusted to around 70% or 80%.

[0043] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
