Description

Technical Field

[0001] This invention relates to the field of green building technology, and more specifically, to a self-regulating, breathable, and heat-insulating wall for green buildings. Background Technology

[0002] Existing technologies commonly employ phase change materials (PCMs) combined with wall structures to create insulated walls, which absorb or release heat to maintain a constant temperature. In residential buildings, to achieve insulation, large areas of the walls are typically covered with insulated panels, leaving only a few windows for ventilation. While office buildings often use double-glazed windows to increase light transmission, this still doesn't solve the ventilation and air exchange problem, requiring continuous air circulation using exhaust fans. Traditional window ventilation requires manual operation or automatic opening with smart home appliances; these are all active ventilation methods. Therefore, the technical problem this invention aims to solve is how to achieve passive air circulation between the inside and outside of a building without using any electrical equipment, thereby improving indoor air quality. Summary of the Invention

One end of the limiting clamp is connected to the indoor end, and the other end is movably connected to the limiting protrusion. The limiting sleeve is sleeved on the outside of the limiting clamp. The limiting sleeve is located between the outer wall of the inner pipe and the inner wall of the fixed pipe. One end of the limiting sleeve abuts against the abutting ring. The limiting clamp is connected to the fixed pipe through the limiting sleeve.

[0017] Preferably, the limiting protrusion is composed of a surface contact section, an end contact section, and a critical section. The end contact section and the surface contact section are connected by the critical section. The end contact section is located on the side closer to the cover, and the surface contact section is located on the side closer to the indoor end. Both the surface contact section and the end contact section have a non-zero angle with the outer wall of the air intake pipe.

[0018] Preferably, the angle α between the surface contact section and the intake pipe is smaller than the angle β between the end contact section and the intake pipe.

[0029] The ventilation mechanism can be controlled to open and close based on temperature changes.

[0030] When the temperature is higher than the opening threshold of the ventilation mechanism and the outside wind force is less than the opening threshold of the ventilation mechanism, the ventilation mechanism is opened, and outside air can enter the room through the ventilation mechanism to achieve indoor and outdoor air circulation.

[0031] When the temperature is below the opening threshold of the ventilation mechanism, or when the outside wind force exceeds the opening threshold of the ventilation mechanism, the ventilation mechanism closes, preventing outside air from entering the room. Through the design of the above structure, the self-ventilating function of the insulated wall can be achieved without using any electrical equipment.

[0032] The self-regulating breathable and heat-insulating wall for green buildings described in this invention, other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention.

Detailed Implementation

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0046] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0047] like Figures 1-10 As shown, this invention provides a self-regulating, breathable, and heat-insulating wall for green buildings, comprising: an outer wall 100, an inner wall 200, and a phase change material layer 300 disposed between the outer wall 100 and the inner wall 200. The wall has through holes, and a ventilation mechanism is disposed within each through hole. A limiting sleeve 6 made of shape memory alloy or thermoplastic elastomer is disposed within the ventilation mechanism, allowing the opening and closing of the ventilation mechanism to be controlled by temperature changes.

[0048] When the temperature is higher than the opening threshold of the ventilation mechanism and the outside wind force is less than the opening threshold of the ventilation mechanism, the ventilation mechanism is opened, and outside air can enter the room through the ventilation mechanism to achieve indoor and outdoor air circulation.

[0049] When the temperature is below the opening threshold of the ventilation mechanism, or when the outside wind force exceeds the opening threshold of the ventilation mechanism, the ventilation mechanism closes, preventing outside air from entering the room. Through the design of the above structure, the self-ventilating function of the insulated wall can be achieved without using any electrical equipment.

[0050] It is important to note that the effect of temperature on the opening threshold of the ventilation mechanism varies depending on the material chosen. For example, when polyurethane elastomer or hydrogenated styrene-butadiene copolymer is used as the limiting sleeve 6, the opening threshold is 20 degrees Celsius. When the temperature exceeds 20 degrees Celsius, the ventilation mechanism opens. When the temperature is between 10 and 20 degrees Celsius, it is the critical value of the opening threshold. When the temperature is below 10 degrees Celsius, the ventilation mechanism closes. Similarly, depending on the material chosen, the effect of wind force on the opening threshold of the ventilation mechanism also varies. The opening threshold is usually adapted to the elasticity provided by the limiting sleeve 6.

[0051] Furthermore, the ventilation mechanism comprises a cover 1, a fixing tube 2, a threshold adjustment component, and an indoor end 3. The cover 1 is located at the end of the fixing tube 2 near the outer wall 100. The outer wall of the fixing tube 2 is connected to the inner wall of the through hole. The opening of the through hole on the movable side of the outer wall 100 is tapered, which can effectively prevent rainwater from flowing back into the through hole. The edge of the cover 1 is tapered to match the tapered opening. Figures 8-10 As shown, the tapered edge design allows the cover 1 to form a complete plane with the outer wall 100 when it abuts against the fixed pipe 2, preventing birds from encroaching on the through hole. It also facilitates the connection of the cover 1 to the through hole when installing the ventilation mechanism. Both the threshold adjustment component and the indoor end 3 are located inside the fixed pipe 2. The indoor end 3 is located at the end of the fixed pipe 2 closest to the inner wall 200, and is connected to the cover 1 via the threshold adjustment component.

[0052] When the ventilation mechanism is activated, the cover 1 is fully opened, at which point the cover 1 and the end of the fixing tube 2 are at a first distance, such as... Figure 8 As shown, the indoor and outdoor ventilation volume is at its maximum at this time;

[0053] When the ventilation mechanism is at the critical value of the opening threshold, the cover 1 is not fully open. At this time, there is a second distance between the cover 1 and the end of the fixed tube 2. Usually, the second distance needs to be smaller than the first distance to reduce the air circulation area. Figure 9 As shown, the critical value is a range value. For example, the critical value range of the temperature opening threshold is between 10 degrees Celsius and 20 degrees Celsius. This is usually the spring and autumn seasons because the temperature difference between day and night is large. The half-open cover 1 can reduce the loss of heat indoors.

[0054] When the ventilation mechanism is closed, the cover 1 abuts against the end of the fixed tube 2.

[0055] Furthermore, an abutment ring 21 is provided at one end of the fixed pipe 2 near the outer wall 100. An inner tube 22 is provided on the inner hole of the abutment ring 21. The fixed pipe 2 is installed in the through hole, and the outer wall of the fixed pipe 2 abuts against the inner wall of the through hole. The outer wall of the abutment ring 21 is connected to the inner wall of the fixed pipe 2, and the outer wall of the inner tube 22 is connected to the inner wall of the abutment ring 21. The inner tube 22 extends from the abutment ring 21 toward the indoor end 3. There is a third distance between the outer wall of the inner tube 22 and the inner wall of the fixed pipe 2, forming a fixed space for installing the threshold adjustment component. Figure 7 As shown;

[0056] When the ventilation mechanism is open, the cover 1 and the abutment ring 21 have a first distance;

[0057] When the ventilation mechanism is at the critical value of the opening threshold, the cover 1 and the abutment ring 21 have a second distance;

[0058] When the ventilation mechanism is closed, the cover 1 abuts against the abutment ring 21.

[0059] Furthermore, the threshold adjustment component comprises an air intake pipe 4, a limiting clamp 5, a limiting sleeve 6, and a reset component 7. One end of the air intake pipe 4 is connected to the cover 1. Typically, the cover 1 has a threaded groove, and the end of the air intake pipe 4 has an external thread. The two are then installed using a threaded connection. Figures 1-3 As shown, this facilitates the disassembly and assembly of the ventilation mechanism. The other end of the air inlet pipe 4 is connected to the indoor end 3 via the reset component 7. The reset component 7 can be a commercially available product or existing technology that is elastic and does not affect the airflow, such as a spring.

[0060] The side wall of the air intake pipe 4 is provided with a plurality of air intake holes 41, and the outer diameter of the air intake pipe 4 is smaller than the inner diameter of the inner pipe 22, such as... Figure 1 and Figures 7-10 As shown, an airflow channel for gas circulation is formed between the outer wall of the air inlet pipe 4 and the inner wall of the inner pipe 22. When the venting mechanism is opened, outside air can enter the airflow channel through the gap between the cover 1 and the abutment ring 21, and then enter the air inlet pipe 4 through the air inlet hole 41, and then reach the indoor end 3 through the reset member 7, and finally enter the room from the indoor end.

[0061] The outer wall of the air intake pipe 4 is provided with a limiting protrusion 42, and the limiting clamp 5 is sleeved on the outside of the air intake pipe 4. One end of the limiting clamp 5 is connected to the indoor end 3, and the other end is movably connected to the limiting protrusion 42. The mutual cooperation between the limiting protrusion 42 and the limiting clamp 5 forms the open state, the critical value state, and the closed state of the ventilation mechanism.

[0062] The limiting sleeve 6 is sleeved on the outside of the limiting clamp 5. The limiting sleeve 6 is located between the outer wall of the inner tube 22 and the inner wall of the fixed tube 2. One end of the limiting sleeve 6 abuts against the abutting ring 21. The limiting clamp 5 is connected to the fixed tube 2 through the limiting sleeve 6.

[0063] Furthermore, the limiting protrusion 42 is composed of a surface contact section 421, an end contact section 422, and a critical section 423. The end contact section 422 and the surface contact section 421 are connected by the critical section 423. The end contact section 422 is located on the side closer to the cover 1, and the surface contact section 421 is located on the side closer to the indoor end 3. Both the surface contact section 421 and the end contact section 422 have a non-zero angle with the outer wall of the air intake pipe 4. The angle α between the surface contact section 421 and the air intake pipe 4 is smaller than the angle β between the end contact section 422 and the air intake pipe 4. According to design requirements, the critical section 423 can be parallel to the outer wall of the air intake pipe 4, or it can be an arc transition between the surface contact section 421 and the end contact section 422, or it can be the inflection point between the surface contact section 421 and the end contact section 422.

[0064] When the ventilation mechanism is activated, the limiting clamp 5 is located on the surface contact section 421;

[0065] When the ventilation mechanism is at the critical value of the opening threshold, the limit clamp 5 is located on the critical segment 423;

[0066] When the ventilation mechanism is closed, the limit clamp 5 is located on the end contact section 422.

[0067] Furthermore, the limiting clamp 5 is composed of a connecting section 51 connected to the indoor end 3, a fixing section 52 located between the indoor end 3 and the limiting sleeve 6, a first deformable section 53 selectively connected to the inner wall of the limiting sleeve 6, and an abutting section 54 abutting against the limiting protrusion 42. One end of the first deformable section 53 is connected to the connecting section 51 through the fixing section 52, and the other end of the first deformable section 53 is connected to the abutting section 54. The included angle θ between the first deformable section 53 and the abutting section 54 is less than 90 degrees. The side of the abutting section 54 closest to the air intake pipe 4 is the abutting surface. The end of the abutting section 54 is arc-shaped. The abutting surface of the abutting section 54 can abut against the end of the inner pipe 22, so that the included angle between the first deformable section 53 and the abutting section 54 is always less than 90 degrees.

[0068] When the ventilation mechanism is activated, the abutment surface of the abutment section 54 abuts against the surface contact section 421, and the reset member 7 is under tension. Figure 8 As shown. When the ventilation mechanism is activated, it indicates that the temperature has exceeded the activation threshold. At this time, the ventilation mechanism needs to consider how to automatically adjust the distance between the cover 1 and the abutment ring 21 when encountering strong winds (such as those caused by heavy rain or typhoons). Since most extreme weather events are short-lived thunderstorms and strong winds, the ventilation mechanism also needs to be able to automatically reset after the extreme weather ends.

[0069] In this embodiment, when the wind force is too strong, it will push the cover 1 towards the abutment ring 21, and relative sliding will occur between the abutment surface of the abutment section 54 and the surface contact section 421, adjusting the airflow area to... Figure 8 For example, when the wind is too strong, it will push the cover 1 to move to the right, which will drive the air intake pipe 4 to move to the right. The contact surface of the surface contact section 421 and the contact surface of the contact section 54 will move relative to each other and compress the contact section 54. This will cause the first deformation section 53 to squeeze the limiting sleeve 6. At this time, the limiting sleeve 6 has a large elasticity and can adapt to the pressure of the first deformation section 53, thus providing sufficient deformation space for the first deformation section 53. When the wind weakens or stops, the reset part 7 and the limiting sleeve 6 cooperate with the first deformation section 53 to drive the contact section 54 to reset, which will then push the air intake pipe 4 to move to the left, thereby resetting the cover 1.

[0070] When the ventilation mechanism is at the critical value of the opening threshold, the end of the abutment section 54 abuts against the critical section 423. At this time, the reset member 7 is in a non-stressed state (because the tension or pressure is small, it can be ignored). Figure 9 As shown, the end of the abutting section 54 is located on the critical section 423. The first deformable section 53 is squeezed to abut against the limiting sleeve 6. Because the temperature is within the critical value range at this time, the limiting sleeve 6 still has a certain elasticity and can be squeezed and deformed by the first deformable section 53. However, its elasticity is insufficient to support the first deformable section 53 to reset, thus making the cover 1 in a semi-open state. Similarly, in order to avoid the influence of strong winds, the end of the abutting section 54 can also move relative to the critical section 423 to adjust the distance between the cover 1 and the abutting ring 21.

[0071] When the ventilation mechanism is closed, the end of the abutment section 54 abuts against the end contact section 422, and the reset member 7 is in a state of compression force, such as Figure 10 As shown; because the temperature has fallen below the critical value of the opening threshold, the limiting sleeve 6 has essentially lost its elasticity, and at this point, the limiting sleeve 6 can be considered a rigid body for limiting. Figure 10 For example, the reset member 7 pushes the intake pipe 4, causing it to tend to move to the left. The end of the abutting section 54 is located near the critical section 423 of the end contact section 422. The abutting section 61 squeezes the first deformed section 53, and the first deformed section 53 abuts against the limiting sleeve 6, thereby limiting the intake pipe 4.

[0072] When the temperature rises back to the critical value range, the elasticity of the limiting sleeve 6 gradually increases, enabling it to gradually provide deformation space for the first deformation section 53. Under the push of the reset member 7, the end of the abutment section 54 will move to the critical section 423. At this time, the ventilation mechanism changes from the closed state to the critical value of the opening threshold.

[0073] Furthermore, the limiting sleeve 6 is made of shape memory alloy or thermoplastic elastomer. The limiting sleeve 6 consists of an abutting end 61 that abuts against the abutting ring 21, an extrusion end 62 for fixing the fixing section 52, and a second deformable section 63. The second deformable section 63 is provided with a groove that is adapted to the first deformable section 53.

[0074] When the ventilation mechanism is activated, there is a fourth distance between the outer wall of the first deformable section 53 and the groove, thereby ensuring that the first deformable section 53 has sufficient deformation space when the abutting surface of the abutting section 54 moves relative to the surface contact section 421.

[0075] When the ventilation mechanism is at the critical value of the opening threshold, the first deformable section 53 is located in the groove and abuts against the second deformable section 63.

[0076] When the ventilation mechanism is closed, there is a fifth distance between the outer wall of the first deformable section 53 and the groove.

[0077] The opening threshold can include both temperature threshold and wind force threshold. By making the limiting sleeve 6 with different materials, the temperature threshold can be adjusted. By setting the groove, the limiting clamp 5 and the reset piece 7 can adjust the wind force threshold.

[0078] The indoor end 3 is provided with a first hole 31 and a second hole 32. One end of the first hole 31 is connected to the air intake pipe 4, and the other end is connected to one end of the second hole 32. The other end of the second hole 32 is connected to the interior. The inner diameter of the first hole 31 is larger than the outer diameter of the air intake pipe 4 and larger than the inner diameter of the second hole 32. This allows the first hole 31 to form an inner end face extending into the interior of the indoor end 3 at the position where it connects with the second hole 32. Figure 3 and Figure 4 As shown.

[0079] One end of the reset component 7 is connected to the end of the intake pipe 4, and the other end is connected to the inner end face of the first hole 31, such as... Figure 1 As shown, the outer wall of the indoor end 3 is provided with a limiting platform. The ends of the fixed section 52 and the extrusion end 62 are both in contact with the limiting platform. The indoor end 3 is provided with an annular groove that is adapted to the connecting section 51. The connecting section 51 is located in the annular groove, thereby realizing the position limitation of the limiting clamp 5, the limiting sleeve 6 and the reset member 7 by the indoor end.
