Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, and in particular to a ventilation device for building design. Background Technology

[0002] As is well known, architectural design refers to the process by which designers, before construction begins, comprehensively envision the problems that may exist or occur during the construction and use of a building, and formulate solutions and plans, expressing them in drawings and documents. Among these, building ventilation is a crucial aspect of architectural design. Building ventilation is divided into natural ventilation and mechanical ventilation. It refers to the direct or purified exhaust of polluted indoor air to the outside, followed by the replenishment of fresh air, thereby maintaining the indoor air environment in accordance with hygiene standards. Its purpose is to ensure the removal of indoor pollutants and the thermal comfort of indoor occupants, meeting their need for fresh air.

This utility model can reduce the entry of dust and moisture into the ventilation duct, and can also clean up fine dust that seeps into the ventilation duct in a timely manner, ensuring that it is filtered and adsorbed to the maximum extent before entering the building interior, thus avoiding adhesion to the inner wall of the duct and affecting its use, and also preventing it from entering the interior and polluting the indoor environment, with obvious practical effects," Announcement No. "

[0004] The patent "CN217900101U" reduces the amount of dust and moisture entering ventilation ducts and can promptly clean up fine dust that seeps into the ducts, ensuring maximum filtration and adsorption before it enters the building interior. This prevents dust from adhering to the inner wall of the duct and affecting its use, and also prevents it from entering the interior and polluting the indoor environment.

[0005] However, the above-mentioned patents have certain limitations in use. The ventilation volume and direction are difficult to adjust, making it difficult to meet the ventilation needs of different scenarios; the operation is unstable and the components are prone to interference, which shortens the life of the device and reduces the ventilation effect; the air purification is insufficient, affecting indoor air quality; and the lack of equipment information labeling is not conducive to operation and maintenance.

[0006] Therefore, a ventilation device for building design is proposed to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a ventilation device for building design to solve the above-mentioned problems, which improves the difficulties in adjusting ventilation volume and direction, making it difficult to meet the ventilation needs of different scenarios; unstable operation and easy interference of components, which shortens the life of the device and reduces the ventilation effect; insufficient air purification, which affects indoor air quality; and lack of equipment information labeling, which is not conducive to operation and maintenance.

[0008] This utility model achieves the above-mentioned objective through the following technical solution: a ventilation device for building design, comprising:

[0009] The ventilation body has an air inlet and an air outlet at its front and rear ends, respectively. Air inlet pipes are installed at both ends of the air inlet and the air outlet. A ventilation cavity is formed inside the ventilation body.

[0010] An adjusting sleeve is rotatably connected to the ventilation cavity. A fan blade is installed inside the adjusting sleeve. A motor is fixedly connected to one end of the fan blade, and the output end of the motor is fixedly connected to the drive end of the fan blade.

[0011] A grip, which is fixedly connected to the circumferential surface of the adjusting sleeve;

[0012] It also includes a limiting mechanism located on the upper side of the ventilation body, which is used to limit the rotation angle of the handle.

[0013] Preferably, the limiting mechanism includes:

[0014] A connecting knob, which is fixedly connected to the top of the ventilation body;

[0015] A fixing rod is fixedly connected to the top of the ventilation body;

[0016] A ratchet tooth, which is rotatably connected to the top of the ventilation body;

[0017] A spring, which is fixedly connected to the adjacent ends of the ratchet and the connecting torque;

[0018] The transmission gears are provided in two parts, and the two transmission gears are respectively fixedly connected to the circumferential surfaces of the handle and the ratchet.

[0019] Preferably, air filters are fixedly connected to the inner circumference of both the air inlet duct and the air outlet duct, and labels are fixedly connected to both ends of the ventilation body.

[0020] Preferably, mounting holes are provided at both ends of the ventilation body.

[0021] Preferably, two corner plastic pads are fixedly connected to the circumferential surface of the ventilation body.

[0022] Preferably, the top of the ventilation body is provided with a protective cover, which is fitted onto the outer surface of the two transmission gears.

[0024] The beneficial effects of this utility model are:

[0025] 1. It is equipped with an adjusting sleeve, a handle, and a limiting mechanism. The adjusting sleeve is rotatably connected to the ventilation cavity. By manually operating the handle, the adjusting sleeve can be rotated, thereby adjusting the angle of the fan blades and changing the direction and flow of air. The limiting mechanism ensures that the adjustment is carried out within a safe range and prevents over-adjustment. It can meet the ventilation needs in different scenarios. When the wind force changes, the ventilation volume can be adjusted according to the actual situation to save energy. In areas with large differences in indoor air quality, the ventilation direction can be adjusted in a targeted manner to improve the ventilation effect and enhance the comfort of the indoor environment.

[0026] 2. The connecting torque, fixing rod, ratchet, spring, and transmission gear in the limiting mechanism work together. When the handle rotates, the transmission gear drives the ratchet to rotate, and the spring stores elastic potential energy. When the preset limit angle is reached, the fixing rod blocks the ratchet, limiting the further rotation of the handle and adjusting sleeve. This avoids collision and interference between the fan blades and the internal structure of the ventilation cavity, extending the service life of the ventilation device and reducing maintenance costs and frequency. It also ensures stable operation of the ventilation device, continuously and effectively providing good ventilation for the room, protecting indoor air quality, and benefiting personnel health.

Detailed Implementation

[0032] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In practical implementation: such as Figures 1-4 As shown,

[0034] A ventilation device for building design, comprising:

[0035] The ventilation body 1 has an air inlet 8 and an air outlet 9 at its front and rear ends, respectively. Air inlet ducts 6 are installed at both ends of the air inlet 8 and the air outlet 9. A ventilation cavity is formed inside the ventilation body 1. 20;

[0036] An adjusting sleeve 11 is rotatably connected to the ventilation cavity. Inside the 20, a fan blade 13 is installed inside the adjusting sleeve 11. A motor 12 is fixedly connected to one end of the fan blade 13, and the output end of the motor 12 is fixedly connected to the drive end of the fan blade 13.

[0037] The handle 5 is fixedly connected to the circumferential surface of the adjusting sleeve 11;

[0038] It also includes a limiting mechanism, which is located on the upper side of the ventilation body 1 and is used to limit the rotation angle of the handle 5.

[0039] In a specific embodiment of this utility model, the ventilation body 1 serves as the core supporting structure of the entire ventilation device. The ventilation cavity 20 within it provides a channel for air circulation. The air inlets 8 and outlets 9 at the front and rear ends are respectively connected to the air inlet pipes 6, forming a complete air circulation path, allowing indoor and outdoor air to exchange through the device. The layout design of the air inlets 8 and outlets 9 ensures that air can enter and exit in an orderly manner, guaranteeing a stable and efficient ventilation process.

[0040] Air inlet 8 and air outlet 9 are the interfaces for air exchange between the ventilation unit 1 and the outside environment. Air inlet 8 is used to introduce fresh outside air, and air outlet 9 is used to exhaust stale indoor air. Their reasonable arrangement allows air to flow in a predetermined direction, ensuring ventilation effect. At the same time, their size and shape design also affect the air velocity and flow rate.

[0041] The air intake duct 6 connects the ventilation unit 1 to the external environment of the building, guiding air into the ventilation unit 1. It delivers outdoor air to the air inlet 8, ensuring the stability and directionality of the air intake. Its length and diameter can be adjusted according to the actual layout of the building to adapt to different installation environments, ensuring that the ventilation system can effectively cover the target area.

[0042] The adjusting sleeve 11 is rotatably connected to the ventilation cavity 20, and its angle and position within the ventilation cavity 20 can be changed by rotation. The rotation of the adjusting sleeve 11 can drive the internal fan blades 13 to adjust their direction, thereby changing the airflow direction and flow rate, and realizing flexible adjustment of ventilation volume and ventilation direction to meet the ventilation needs in different scenarios, such as optimizing the ventilation effect when there are changes in wind force or differences in indoor air quality.

[0043] Driven by the motor 12, the fan blades 13 rotate and are a key component for achieving airflow. The airflow generated by the rotation of the fan blades 13 draws outside air into the ventilation chamber 20 through the air inlet 8 and pushes the air out through the air outlet 9, completing the ventilation process. Its shape, size, and number directly affect the ventilation efficiency and air volume of the ventilation device.

[0044] Motor 12 provides the power source for the rotation of fan blade 13, driving the fan blade 13 to rotate through its output end, ensuring the continuous operation of the ventilation device. The power and speed of motor 12 can be selected according to actual needs to meet the requirements of different ventilation intensities. At the same time, the stability and reliability of motor 12 are also related to the service life and operating effect of the ventilation device.

[0045] The handle 5 is fixedly connected to the circumferential surface of the adjusting sleeve 11, providing the operator with a point of leverage for adjusting the adjusting sleeve 11. By manually operating the handle 5, the adjusting sleeve 11 can be rotated conveniently and quickly, thereby adjusting the angle of the fan blade 13 and the ventilation direction. This allows the operator to flexibly control the ventilation device according to actual ventilation needs, enhancing the convenience and flexibility of the device.

[0046] The limiting mechanism is located on the upper side of the ventilation body 1, and its main function is to limit the rotation angle of the handle 5. By limiting the rotation angle of the handle 5, the excessive rotation of the adjusting sleeve 11 is prevented, and the collision or interference between the fan blade 13 and the internal structure of the ventilation cavity 20 is avoided. This ensures that the adjusting sleeve 11 and the fan blade 13 are adjusted within a safe angle range, and also makes the adjustment of the ventilation device controllable, ensuring the stability and consistency of the ventilation effect.

[0047] Please refer to the details. Figures 1-4 The limiting mechanism includes:

[0048] Connecting screw 18 is fixedly connected to the top of the ventilation body 1;

[0049] Fixed rod 19, fixedly connected to the top of ventilation body 1;

[0050] Ratchet 16 is rotatably connected to the top of the ventilation body 1;

[0051] A spring is fixedly connected to the adjacent ends of the ratchet 16 and the connecting torque 18;

[0052] There are two transmission gears 15, which are fixedly connected to the circumferential surfaces of the handle 5 and the ratchet 17, respectively.

[0053] In this embodiment: when the operator grips and rotates the handle 5, the transmission gear 15 fixedly connected to the handle 5 rotates accordingly. This transmission gear 15 drives another transmission gear 15 connected to the ratchet 17 to rotate through a meshing relationship, thereby causing the ratchet 16 to rotate around its rotational connection point with the ventilation body 1. During this process, the spring connecting the ratchet 16 and the connecting torque 18 will be stretched or compressed due to the rotation of the ratchet 16, storing elastic potential energy.

[0054] When the handle 5 is rotated to the preset limit angle, the fixing rod 19 will prevent the ratchet 16 from continuing to rotate. At this time, the ratchet 16 and the transmission gear 15 remain engaged, limiting the transmission gear 15 from continuing to rotate, thereby preventing the handle 5 and the adjusting sleeve 11 from rotating further, and avoiding collision and interference between the fan blade 13 and the internal structure of the ventilation cavity 20.

[0055] When the handle 5 needs to be adjusted in the reverse direction, the operator must apply a certain external force to overcome the elastic potential energy of the spring, causing the ratchet 16 to disengage from the transmission gear 15, thereby releasing the limit and realizing the reverse rotation adjustment of the handle 5. After adjustment, release the handle 5, the spring releases its elastic potential energy, pushes the ratchet 16 back to its original position, re-engages with the transmission gear 15, and locks the angle of the handle 5, ensuring the stable operation of the ventilation device after adjustment.

[0056] Please refer to the details. Figures 1-4 Air filters 10 are fixedly connected to the inner circumference of both the air inlet duct 6 and the air outlet duct 14, and labels 3 are fixedly connected to both ends of the ventilation body 1.

[0057] In this embodiment, the air filter 10, which is fixedly connected to the inner circumference of the air inlet duct 6 and the air outlet duct 14, plays a synergistic purification role. When outside air enters the ventilation body 1 through the air inlet duct 6, the air filter 10 in the air inlet duct 6 can intercept particulate matter such as dust, hair, and pollen in the air, preventing impurities from entering the ventilation cavity 20, preventing them from clogging the fan blades 13 or depositing inside the ventilation body 1, and ensuring the normal operation of the fan blades 13 and ventilation efficiency.

[0058] The labels 3, fixedly connected to both ends of the ventilation body 1, are used to identify key equipment information and assist in practical applications. During installation, parameters such as equipment model, rated power, installation date, and maintenance cycle can be marked on the labels 3 to help operators quickly understand the equipment performance.

[0059] Please refer to the details. Figures 1-4 The ventilation body 1 has mounting holes 101 at both ends.

[0060] In this embodiment, the mounting holes 101 at both ends of the ventilation body 1 are the key structure for achieving fixed installation of the device. During installation, bolts, screws, and other connecting parts pass through the mounting holes 101 to firmly fix the ventilation body 1 to the building wall, ceiling, or specific bracket, ensuring that the device remains stable during operation and avoiding displacement or noise caused by vibration.

[0061] Please refer to the details. Figures 1-4 Two corner plastic pads 2 are fixedly connected to the circumferential surface of the ventilation body 1.

[0062] In this embodiment, the corner plastic pads 2 fixedly connected to the circumferential surface of the ventilation body 1 play a dual role during installation and operation. During installation, the plastic pads, through their elastic cushioning effect, fill the gap between the ventilation body 1 and the mounting surface, reducing stress concentration caused by uneven mounting surfaces and preventing deformation of the outer shell of the ventilation body 1.

[0063] Please refer to the details. Figures 1-4 The top of the ventilation body 1 is provided with a protective cover 4, which is fitted onto the outer surface of the two transmission gears 15.

[0064] In this embodiment, the protective cover 4 at the top of the ventilation body 1 is fitted onto the outer surface of the transmission gear 15, forming a protective barrier. When the device is running, the protective cover 4 can prevent dust and debris from entering the meshing area of ​​the transmission gear 15, preventing foreign objects from causing the gear to jam, wear, or fail to transmit power, ensuring the normal meshing of the ratchet 16 and the transmission gear 15, and maintaining the precise adjustment function of the limit mechanism.

[0065] Please refer to the details. Figures 1-4 Both the far ends of the air inlet duct 6 and the air outlet duct 14 are fixedly connected with a closed cover 7.

[0066] In this embodiment, the sealed cover 7, which is fixedly connected to the far ends of the air inlet duct 6 and the air outlet duct 14, plays a key role in ensuring the performance of the ventilation device and the safety of the building environment. In the non-ventilated state, the sealed cover 7 tightly covers the duct port, forming a physical barrier that can effectively prevent rainwater, dust, insects and debris from entering the duct.

[0067] In use, when installing the ventilation device, the ventilation body 1 is first fixed to the building wall, ceiling, or specific bracket using bolts, screws, or other connecting parts via the mounting holes 101 at both ends. Simultaneously, the corner plastic pads 2 provide elastic cushioning to prevent deformation of the ventilation body 1's outer shell due to uneven mounting surfaces. After installation, labels 3 are fixed to both ends of the ventilation body 1 to indicate key equipment information. During use, the operator holds the handle 5 and rotates it, causing the adjusting sleeve 11 to rotate within the ventilation cavity 20, thereby adjusting the direction of the fan blades 13 and achieving flexible adjustment of ventilation volume and direction. During this process, the handle 5 drives the transmission gear 15 to rotate, which in turn causes the ratchet 16 to rotate via the ratchet 17, stretching or compressing the spring. When the handle 5 rotates to the preset limit angle, the fixing rod 19 blocks the ratchet 16 to prevent over-adjustment. To reverse the adjustment, the spring force is overcome to disengage the ratchet 16 from the transmission gear 15. After adjustment, the spring pushes the ratchet 16 back to lock the handle 5. When the motor 12 is started, the fan blades 13 rotate. Outside air enters the ventilation chamber 20 after being filtered by the air filter 10 in the air inlet duct 6, and is then discharged through the air outlet 9 and the air outlet duct 14. The air filter 10 in the air outlet duct 14 filters impurities again, and during operation, the protective cover 4 prevents dust and debris from entering the area of ​​the transmission gear 15, ensuring the normal operation of the limit mechanism. When not ventilating, the sealing covers 7 at the ends of the air inlet duct 6 and the air outlet duct 14 prevent foreign objects from entering the ducts.

[0068] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
