Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building ventilation, in particular to an energy-saving air purification and ventilation integrated system. BACKGROUND

[0002] During the use of buildings, maintaining the air freshness of the internal environment is a key link to ensure the health and comfort of users, and ventilation is the core means to achieve this goal.

[0003] When ventilating a building, a ventilation device needs to be used. In related technologies, such as Chinese patent CN116642232B, an energy-saving ventilation device for green buildings is disclosed, which includes a non-powered air cap. In use, the non-powered air cap mainly relies on two natural driving forces: one is the temperature difference effect between the inside and outside of the building. When the air inside the building becomes less dense due to temperature rise, natural updrafts are formed. These updrafts are guided by the arc-shaped blades of the non-powered air cap to be sprayed in a specific direction and to drive the whole air cap to rotate. The other is the direct driving of external wind. When there is natural wind outside the building, the wind acts on the arc-shaped blades of the non-powered air cap, thereby driving the air cap to rotate. The rotation of the air cap causes a negative pressure effect inside the building, thereby more efficiently attracting other air inside the building to be discharged.

[0004] However, the above-mentioned non-powered air cap is prone to eccentricity when working in a strong wind environment, which causes the whole air cap to vibrate violently and frequently collide and rub with the surrounding fixed structure, aggravating the damage to the structure. In severe cases, the arc-shaped blades may be deformed, broken or detached, resulting in the loss of the ventilation function of the air cap. SUMMARY

[0035] The embodiments of the present application will be described below with reference to Figures 1 to 8 The energy-saving air purification and ventilation integrated system provided by the embodiments of the present application is particularly suitable for ventilation of buildings.

[0036] Specifically, the energy-saving air purification and ventilation integrated system is provided with a hood base 1 and a hood body 2, wherein the hood base 1 comprises a wind pipe 101 and a support 102. The wind pipe 101 is vertically arranged during installation, is fixed to the top of the building, and is in communication with the inside of the building to facilitate receiving air inside the building. The support 102 is arranged at the top of the wind pipe 101, and the support 102 comprises a base ring 1021. The base ring 1021 is vertically arranged, and the top end of the wind pipe 101 is inserted into the side wall of the base ring 1021 during installation, and can be fixedly connected with the base ring 1021 through fasteners such as bolts, nuts or rivets.

[0037] The hood body 2 comprises a support rod 201 vertically arranged; for the convenience of installing the support rod 201, a plurality of supporting legs 1022 are arranged on the inner circumferential wall of the base ring 1021, the plurality of supporting legs 1022 are arranged in a circumferential direction, and the inner ends of the plurality of supporting legs 1022 are jointly provided with a fixing sleeve 1023 vertically arranged, and the support rod 201 is fixedly inserted into the fixing sleeve 1023 during installation. A top cover 202 is arranged at the top of the support rod 201, and the top cover 202 and the support rod 201 are vertically arranged; a first clamping plate 211 is arranged below the top cover 202, the first clamping plate 211 is sleeved on the outer periphery of the support rod 201 and is arranged in a spaced manner with the support rod 201 to avoid rotating wear, and the first clamping plate 211 is fixedly connected with the top cover 202 through fasteners such as bolts, nuts or rivets; a bearing 210 is also sleeved on the support rod 201, and the bearing 210 is located between the first clamping plate 211 and the top cover 202 to ensure that the top cover 202 can rotate around the support rod 201. A base 203 is sleeved on the support rod 201, the base 203 has a ring structure and is vertically arranged and located below the top cover 202, the base 203 is arranged in a spaced manner with the support rod 201, and the base 203 is rotatably connected with the support rod 201 through the bearing 210 to ensure that the base 203 can rotate around the support rod 201.

[0038] A plurality of blades 204 are arranged between the top cover 202 and the base 203, the blades 204 have an arc structure and a concave surface facing the support rod 201, the plurality of blades 204 jointly form a spherical structure, the top cover 202, the base 203 and the plurality of blades 204 jointly form a ventilation space 205, the ventilation space 205 is communicated with the air pipe 101, ventilation openings 2041 are formed between adjacent blades 204 and communicated with the ventilation space 205, so that the air in the building can be discharged to the outside through the air pipe 101, the ventilation space 205 and the ventilation openings 2041; the blades 204 are vertically arranged, and the top ends thereof are fixed on the outer circumferential wall of the top cover 202 by riveting, and the bottom ends thereof are fixed on the outer circumferential wall of the base 203 by riveting.

[0039] During use, when there is no natural wind or the natural wind has a small wind force outside the building, and the air density in the building decreases due to temperature rise, the air in the building will form a natural upward airflow, which can be sequentially discharged to the outside through the air pipe 101, the ventilation space 205 and the ventilation openings 2041, and when passing through the blades 204, the upward airflow will be sprayed in a specific direction under the guidance of the blades 204, and will drive the whole of the blades 204, the top cover 202 and the base 203 to rotate around the support rod 201, and the rotation of the whole of the blades 204, the top cover 202 and the base 203 will further enhance the negative pressure effect in the building, so as to not only more efficiently attract other air in the building to be discharged, but also guide the air outside the building to enter the building, and finally complete the air circulation between the inside and outside of the building.

[0040] When there is natural wind outside the building and the wind force is strong, the wind force acts on the blade 204, which directly drives the blade 204, the top cover 202 and the base 203 to rotate around the support rod 201. The rotation of the blade 204, the top cover 202 and the base 203 will further enhance the negative pressure effect inside the building, so as to more efficiently draw other air out of the building and guide outside air into the building, ultimately completing the air circulation inside and outside the building.

[0041] While the above process can achieve ventilation of the building, in strong winds, the wind exerts a greater force on the blades 204, causing the rotational speed of the blades 204, top cover 202, and base 203 to increase dramatically, far exceeding the rotational speed required for normal ventilation. This excessively high rotational speed causes the components of the wind cap body 2 to experience centrifugal forces far exceeding design standards. These centrifugal forces cause continuous impact and wear on critical parts such as the connecting structures between components and the bearings 210, reducing the service life of the components. Simultaneously, strong winds are not stable, uniform airflows. In strong winds, the direction and intensity of the airflow fluctuate frequently. This unstable airflow generates asymmetrical forces, meaning that the magnitude and direction of the wind force experienced by different parts of the blades 204 vary significantly. This asymmetrical force disrupts the original force balance of the blades 204, causing eccentricity—the rotation center of the blades 204 deviates from the support rod 201. When the blade 204 is in an eccentric rotation state, not only will the rotation process become violent and unstable, producing obvious vibrations, but more importantly, the eccentricity will cause abnormal collisions and friction between the blade 204 and the top cover 202 and the base 203, further aggravating structural damage. In severe cases, it may even cause the blade 204 to deform, break, or detach from the top cover 202 and the base 203, ultimately causing overall damage to the wind cap body 2 and loss of ventilation function.

[0042] Based on this, in the energy-saving integrated air purification and ventilation system provided in this embodiment of the invention, the blade 204 is configured such that its top end abuts against the outer peripheral wall of the top cover 202 during installation, and the bolt passes through the blade 204 and the top cover 202 sequentially from the outside to the inside, and the nut is screwed onto the bolt from the inside to the outside, thereby fixing the position of the blade 204 on the top cover 202, and the top end of the blade 204 can rotate around the bolt; the bottom end of the blade 204 abuts against the outer peripheral wall of the base 203, and the bolt passes through the blade 204 and the base 203 sequentially from the outside to the inside, and the nut is screwed onto the bolt from the inside to the outside, thereby fixing the position of the blade 204 on the base 203, and the bottom end of the blade 204 can rotate around the bolt. Meanwhile, multiple support springs 206 are provided on the inner peripheral wall of the base 203. The support springs 206 extend radially along the support rod 201. The multiple support springs 206 are arranged circumferentially, and a second clamping plate 212 is provided above the inner end, and a third clamping plate 213 is provided below the inner end. The second clamping plate 212 and the third clamping plate 213 are both sleeved on the outer periphery of the support rod 201 and are spaced apart from the support rod 201 to avoid rotational wear. The second clamping plate 212 and the third clamping plate 213 are fixedly connected by fasteners such as bolts, nuts or rivets during installation, and the multiple support springs 206 are clamped together. A bearing 210 is also sleeved on the support rod 201. The bearing 210 is located between the second clamping plate 212 and the third clamping plate 213 to ensure that the base 203 can rotate around the support rod 201.

[0043] During use, when the energy-saving integrated air purification and ventilation system operates in a strong wind environment, such as Figure 5 As shown, taking a wind blowing from right to left as an example, the blade 204 on the right side experiences stronger wind force. Under the influence of the wind, since the two ends of the blade 204 can rotate around the connection points on the top cover 202 and the base 203, the originally arc-shaped blade 204 will gradually unfold under the push of the strong wind, eventually transforming into an approximately straight shape. Compared to the traditional non-powered wind cap where the blade 204 is fixed at both ends, the blade 204 can only undergo excessive inward deformation when strong winds are applied. This single deformation method will cause high local stress concentration in the blade 204, which is prone to breakage or permanent damage after exceeding the material's tolerance limit. In this system, the blade 204 can switch to an approximately straight shape, which can more evenly distribute the force generated by the strong wind to the overall structure and connection parts of the blade 204, avoiding local stress overload, and thus effectively preventing the blade 204 from being directly damaged by strong winds.

[0044] Meanwhile, when the blades 204 are arc-shaped, a large-area ventilation opening 2041 is formed between adjacent blades 204, facilitating air circulation under normal ventilation conditions. However, in a strong wind environment, the large ventilation opening 2041 increases the probability of wind backflow. Strong wind can enter the ventilation space 205 in the reverse direction through the ventilation opening 2041 and then enter the building interior through the air pipe 101, thereby destroying the normal air circulation in the building interior. When the blades 204 are transformed into a nearly straight shape, the gap between the blades 204 is greatly reduced, and the size of the ventilation opening 2041 is correspondingly reduced, which forms a physical barrier on the ventilation path and significantly weakens the reverse penetration ability of strong wind, thereby reducing the risk of wind backflow.

[0045] In addition, in the process of deforming the blades 204, the bottom end of the blades 204 generates a downward pulling force on the base 203. Since the right blade 204 has the largest deformation degree, the pulling force on the right side of the base 203 is also the strongest, which drives the right side of the base 203 to move downward in the vertical direction, while the left side of the base 203 remains relatively stable due to the smaller force acting thereon, so that the base 203 finally assumes an inclined posture with the right side being lower than the left side. When the right side of the base 203 is inclined downward, the support spring 206 on the right side is stretched or pressed to be elastically deformed along with the movement of the base 203. The elastic deformation of the support spring 206 has a buffering effect, which can absorb a part of the impact force of strong wind transmitted to the base 203 and reduce the direct effect of the impact force on the core components such as the support rod 201 and the bearing 210. At the same time, the restoring force generated by the elastic deformation can counteract the inclination trend of the base 203, prevent the base 203 from being excessively inclined to cause structural imbalance, and thus improve the wind resistance and maintain the relative stability of the system structure.

[0046] After the wind disappears or becomes smaller, the support spring 206 is reset under the elastic action, thereby resetting the base 203 and the blades 204.

[0047] In a further embodiment, to further improve the wind resistance of the energy-saving air purification and ventilation integrated system, an adjusting sleeve 207 is arranged on the base ring 1021, and the adjusting sleeve 207 and the base ring 1021 are arranged in a spaced manner. A blocking table 10212 is fixedly sleeved on the base ring 1021. The blocking table 10212 can be arranged in a ring structure or a plurality of block structures, and the plurality of block structures are arranged in a spaced manner in the circumferential direction. A first elastic member is arranged between the adjusting sleeve 207 and the blocking table 10212. Under the action of the first elastic member, the adjusting sleeve 207 has a tendency to move upward along the axis direction of the adjusting sleeve 207. The first elastic member can be a first compression spring 208, which is arranged vertically and simultaneously sleeved on the outer periphery of the base ring 1021 and arranged in a spaced manner with the base ring 1021.

[0048] A plurality of slots 2072 are arranged on the outer peripheral wall of the adjusting sleeve 207, and the slots 2072 penetrate the upper and lower end faces of the adjusting sleeve 207; a plurality of first clamping protrusions 2031 are formed by inward stamping of the circumferential side wall of the base 203, the plurality of first clamping protrusions 2031 are arranged in the circumferential direction, and are respectively inserted into the slots 2072; under the plug-in cooperation of the first clamping protrusions 2031 and the slots 2072, the base 203 can drive the adjusting sleeve 207 to rotate synchronously; the first clamping protrusions 2031 have a plurality of tooth-shaped structures, the plurality of tooth-shaped structures of the same first clamping protrusion 2031 are arranged in the vertical direction, and all face the adjusting sleeve 207; a second clamping protrusion 2073 is arranged at each slot 2072, the second clamping protrusion 2073 has a plurality of tooth-shaped structures, the plurality of tooth-shaped structures of the same second clamping protrusion 2073 are arranged in the vertical direction, and all face the base 203 and can form clamping cooperation with the plurality of tooth-shaped structures of the first clamping protrusion 2031; under the clamping action of the first clamping protrusion 2031 and the second clamping protrusion 2073, the adjusting sleeve 207 can drive the base 203 to move in the vertical direction. Initially, the first clamping protrusion 2031 is arranged higher and outward than the second clamping protrusion 2073.

[0049] An outer spiral protrusion 10211 is arranged on the outer peripheral wall of the base ring 1021; an inner spiral protrusion 2071 is arranged on the inner peripheral wall of the adjusting sleeve 207, and the inner spiral protrusion 2071 can form transmission cooperation with the outer spiral protrusion 10211, so that the adjusting sleeve 207 can drive the base 203 to move downward synchronously; when the adjusting sleeve 207 moves to the end of the outer spiral protrusion 10211, the adjusting sleeve 207 and the stop table 10212 form stop cooperation and remain stationary, and the base 203 and the blade 204 remain stationary synchronously, so that the problems of component wear and sharp noise caused by high-speed rotation can be avoided.

[0050] To realize the reset of the adjusting sleeve 207, a second elastic member is arranged between the adjusting sleeve 207 and the base ring 1021, and under the action of the second elastic member, the adjusting sleeve 207 has a tendency to move outward in the radial direction; the second elastic member can be reset spring 209, and the number of reset springs 209 is a plurality; to facilitate the installation of the reset spring 209, a plurality of installation grooves are formed on the outer spiral protrusion 10211, the plurality of installation grooves are arranged in the circumferential direction, the installation grooves extend inward to the outer peripheral wall of the base ring 1021, and the reset spring 209 is located at the installation groove. Initially, the reset spring 209 extends upward and outward at the same time.

[0051] During use, when the energy-saving air purification and ventilation integrated system works in a strong wind environment, under the guidance of the blade 204, the wind drives the blade 204, the top cover 202 and the base 203 to rotate as a whole; during the rotation of the base 203, under the clamping action of the first clamping protrusion 2031 and the slot 2072, the base 203 drives the adjusting sleeve 207 to rotate synchronously.

[0052] At the same time, the wind force on the windward side blade 204 is strong, and under the blowing of the wind, it changes from an arc shape to an approximately straight shape, synchronously driving the windward side of the base 203 to move downward, so that the base 203 forms an inclined posture with the leeward side being high and the windward side being low. During the downward movement of the base 203, the windward side edge of the base 203 moves downward and inward, so that the first clamping convex 2031 approaches the second clamping convex 2073; when the first clamping convex 2031 and the second clamping convex 2073 are clamped, the base 203 synchronously drives the adjusting sleeve 207 to move downward and inward, while compressing the reset spring 209, so that the adjusting sleeve 207 forms an inclined posture with the leeward side being high and the windward side being low; when the adjusting sleeve 207 moves to the position where the inner spiral convex 2071 on the windward side and the outer spiral convex 10211 form a transmission cooperation, the adjusting sleeve 207 rotates and moves downward at the same time, synchronously driving the windward side of the base 203 to move downward; when the adjusting sleeve 207 moves to the end of the outer spiral convex 10211, the adjusting sleeve 207 and the stop table 10212 form a stop cooperation and remain stationary, synchronously making the base 203 and the blade 204 remain stationary, so as to avoid the problems of component wear and tear and sharp noise caused by high-speed rotation.

[0053] When the wind force disappears, the adjusting sleeve 207 moves upward to reset under the action of the first compression spring 208, and the windward side of the adjusting sleeve 207 moves outward to reset under the action of the reset spring 209.

[0054] In other embodiments, the first elastic member is a second compression spring, the number of the second compression spring is multiple, and the second compression spring is arranged along the circumference of the support rod 201 and is arranged between the stop table 10212 and the adjusting sleeve 207. Under the action of the second compression spring, the adjusting sleeve 207 has a tendency to move upward.

[0055] In some other embodiments, in order to reduce the situation that the wind flows into the building through the ventilation opening 2041 in special cases, a top wind ring 2032 is arranged on the base 203. The top wind ring 2032 and the base 203 are coaxially arranged, and the outer edge is located outside the blade 204. When the wind blows from top to bottom along the direction of the support rod 201, the top wind ring 2032 moves downward under the blowing of the wind, synchronously driving the bottom end of the blade 204 to move downward through the base 203, so that all the blades 204 change from an arc shape to an approximately straight shape, thereby reducing the ventilation opening 2041 and reducing the risk of wind backflow.

[0056] In some other embodiments, in order to avoid the impurities carried by the wind from damaging the original fresh environment in the building interior when the wind flows back into the building interior through the wind pipe 101, a filter structure is arranged in the base 1 of the wind hat, the filter structure is located at the communication between the base 1 of the wind hat and the building interior, and is configured to be capable of filtering the air. In this way, when the wind flows back into the building interior through the wind pipe 101, the filter structure can filter the impurities carried by the wind, so as to avoid damaging the original fresh environment in the building interior.
