Description

Technical Field

[0001] The utility model belongs to the technical field of fresh air equipment for smart buildings, and particularly relates to fresh air equipment for smart buildings. Background Art

[0002] As an important facility for improving indoor air quality, fresh air equipment in smart buildings has become the choice of more and more families. It not only continuously brings in fresh air, but also effectively reduces indoor pollutants.

[0003] Most of the existing fresh air equipment adopts high-pressure, large-flow fans, relying on mechanical force to supply air into the room from one side and exhaust it to the outside from the other side with a specially designed exhaust fan to force a fresh air flow field to form in the system. While supplying air, the air entering the room is filtered, disinfected, sterilized, oxygenated and preheated by air purification equipment. However, due to the large flow of air during the operation of the fresh air equipment, the telescopic hose will vibrate at the interface of the ventilation pipe mouth. Long-term vibration will cause the connection between the telescopic hose and the ventilation pipe mouth to be damaged.

[0004] Most of the common fresh air equipment in smart buildings in the existing technology do not have the function of limiting and fixing the connection between the telescopic hose and the ventilation pipe outlet, and the telescopic hose cannot be stably fixed at the ventilation pipe outlet of the fresh air equipment. As a result, the telescopic hose will vibrate at the interface of the ventilation pipe outlet during the operation of the fresh air equipment. Long-term vibration will cause damage to the pipeline, affect normal air output, and generate noise, etc.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a fresh air device for a smart building, which can limit and clamp the exhaust ducts, slow down the relative movement between the ducts, and extend the service life of the ducts.

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by a specific embodiment of the present invention is as follows: A fresh air device for a smart building includes: a fresh air device instrument, a limit clamping mechanism, and an air leakage prompt mechanism.

[0008] The fresh air equipment is composed of a processing box and a pair of ventilation pipe openings. The pair of ventilation pipe openings are fixedly assembled on the side of the processing box, and the pair of ventilation pipe openings are connected to the processing box.

[0009] A pair of the limit clamping mechanisms are respectively assembled on the outside of a pair of ventilation pipe openings, and the limit clamping mechanisms include a pair of fixing frames, a pair of the fixing frames are both sleeved on the outside of the ventilation pipe openings, a pair of the fixing frames are both threadedly connected with threaded rods, a pair of the threaded rods are rotatably connected to one end of the fixing frames that is located in the fixing frames, a pair of the arcuate clamping blocks are pressed against the outside of the ventilation pipe openings on one side away from the threaded rods, a pair of the arcuate clamping blocks are both fitted with matching clamping blocks on both sides, and multiple groups of matching clamping blocks are matched with the ventilation pipe openings.

[0010] The air leakage warning mechanism is fixedly installed on the side of the fixing frame. The air leakage warning mechanism includes an air intake pipe, which is arranged to pass through the fixing frame. The end of the air intake pipe away from the fixing frame is connected to a loudspeaker box, and multiple groups of sound balls are placed in the loudspeaker box.

[0011] In one or more embodiments of the present invention, a pair of ventilation pipe openings are each equipped with a telescopic hose at one end away from the processing box. By fixing and sealing the telescopic hoses at the ends of the pair of ventilation pipe openings, ventilation within the smart building can be facilitated through the pair of telescopic hoses.

[0012] In one or more embodiments of the present invention, multiple groups of the mating blocks are fixedly connected to a telescopic rod on a side away from the ventilation pipe opening, the telescopic ends of the multiple groups of the telescopic rods are respectively fixedly connected to the multiple groups of the mating blocks, and the fixed ends of the multiple groups of the telescopic rods are fixedly connected to the fixed frame. By fixedly connecting the multiple groups of the mating blocks to the telescopic ends of the telescopic rods, when the arc-shaped blocks are adjusted to move closer to the ventilation pipe opening by the threaded rod, a pair of arc-shaped blocks adjust the mating blocks to move closer to the ventilation pipe opening, thereby facilitating the mating blocks to move closer to the ventilation pipe opening by the multiple groups of the telescopic rods, so that the multiple groups of the mating blocks cooperate with the arc-shaped blocks to tighten and limit the ventilation pipe opening and the telescopic hose.

[0013] In one or more embodiments of the present invention, a pair of clips are fixedly mounted on the outer sides of each of the pair of fixing frames, and a snap ring is rotatably mounted within each of the pair of clips. By mounting the clips on each of the pair of fixing frames, the clips facilitate locking the fixing frames together, thereby facilitating positioning of the ventilation pipe opening and the telescopic hose via the pair of fixing frames, thereby ensuring a stable connection between the ventilation pipe opening and the telescopic hose.

[0014] In one or more embodiments of the present invention, a pair of snap rings are rotatably connected to a wrench at one end away from the buckle, and the pair of wrenches are hingedly connected to a side of the fixing frame proximal to the buckle. The arrangement of the wrench facilitates adjusting the wrench to rotate sideways on the fixing frame, thereby engaging and locking the snap ring on the side of the wrench with a pair of buckles on the outside of the adjacent fixing frame, thereby securing the pair of fixing frames to the outside of the ventilation pipe opening and the telescopic hose.

[0015] In one or more embodiments of the present invention, an isolation net is fixedly connected to one end of the air intake pipe near the speaker box. The isolation net facilitates confinement of the multiple sets of rattle balls within the speaker box. When air is introduced into the speaker box through the air intake pipe, the air blows the multiple sets of rattle balls to bounce within the speaker box, thereby emitting a sound to prompt maintenance personnel to perform maintenance.

[0016] In one or more embodiments of the present invention, one end of the pair of threaded rods located within the fixing frame is threadedly connected to an adjustment plate, and the pair of adjustment plates are arranged between the fixing frame and the arc-shaped clamping block, and the adjustment plates are arranged to extend through the fixing frame. The arrangement of the adjustment plates facilitates the adjustment of the pair of adjustment plates toward the ventilation pipe opening and the telescopic hose by rotating the fixing frame, thereby facilitating the pair of adjustment plates to press against the outside of the ventilation pipe opening and the telescopic hose to limit the position, thereby reducing the loud vibration between the ventilation pipe opening and the telescopic hose.

[0017] In one or more embodiments of the present invention, a pair of balancing springs are fixedly connected to both ends of a pair of adjustment plates outside the fixed frame, and the pair of balancing springs are symmetrically distributed on both sides of the fixed frame. By fixing the balancing springs on both sides of a pair of adjustment plates, the pair of balancing springs are distributed and pressed against the outside of the ventilation pipe opening and the telescopic hose, so that the pair of balancing springs balance the pair of ventilation pipe openings and the telescopic hose, and the relative movement between the ventilation pipe opening and the telescopic hose is slowed down. The ends of the balancing springs away from the adjustment plates are fixedly connected to a tightening block, and the pair of tightening blocks are respectively matched with the ventilation pipe opening and the telescopic hose. Through the provision of the tightening blocks, it is convenient to press the pair of tightening blocks against the outside of the ventilation pipe opening and the telescopic hose respectively, so that the pair of tightening blocks slow down the relative movement between the ventilation pipe opening and the telescopic hose.

[0018] In one or more embodiments of the present invention, both sides of a pair of the pressing blocks are fitted with fitting plates. By fitting plates fitted on both sides of a pair of pressing blocks, it is convenient to adjust the fitting plates to move closer to the ventilation pipe opening and the telescopic hose through a pair of pressing blocks. A pair of the fitting plates are fixedly connected with fitting springs on the side away from the ventilation pipe opening, and multiple groups of the fitting springs are fixedly connected with receiving plates at one end away from the fitting plates, and multiple groups of the receiving plates are fixedly connected to the side of the fixed frame. Through the provision of the receiving plates, it is convenient to fix multiple groups of fitting springs on the receiving plates, so that the receiving plates adjust the multiple groups of fitting springs to press the ventilation pipe opening and the telescopic hose.

[0019] In one or more embodiments of the present invention, elastic sealing rings are fixedly connected to both sides of a pair of fixing frames, and the pair of abutting blocks and the laminating plate are both assembled in the elastic sealing rings. The provision of the elastic sealing rings facilitates the elastic sealing rings to abut and limit the outside of the ventilation pipe opening and the telescopic hose, thereby slowing down the relative movement between the ventilation pipe opening and the telescopic hose. The provision of the elastic sealing rings can also absorb noise generated during operation of the ventilation pipe opening and the telescopic hose, thereby improving the performance of the fresh air device.

[0020] Compared with the prior art, the utility model can stably fix the telescopic hose on the ventilation pipe opening of the fresh air equipment through the setting of the limit clamping mechanism and the air leakage prompt mechanism, and at the same time can slow down the relative vibration between the telescopic hose and the ventilation pipe opening, reduce the phenomenon of pipeline damage caused by vibration, and can also promptly issue a sound prompt for damaged and leaking pipelines, so that the staff can repair the damaged pipelines in time.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, a fresh air device for a smart building in one embodiment of the present invention includes: a fresh air device instrument 1, a limit clamping mechanism 2, and an air leakage prompt mechanism 3.

[0034] like Figure 1 As shown, the fresh air device 1 is composed of a processing box 101 and a pair of ventilation pipes 102. The pair of ventilation pipes 102 are fixedly mounted on the side of the processing box 101 and are in communication with the processing box 101. The arrangement of the pair of ventilation pipes 102 facilitates ventilation of the smart building through the pair of ventilation pipes 102, so that the air in the smart building is always fresh.

[0035] like Figure 1 As shown, a pair of ventilation pipe openings 102 are each equipped with a telescopic hose 103 at one end away from the processing box 101. By fixing the telescopic hose 103 to the ends of the ventilation pipe openings 102 and sealing the ventilation pipe openings 102 and the telescopic hose 103 with a sealing ring, ventilation inside the smart building can be facilitated through the pair of telescopic hoses 103, ensuring that the air inside the smart building is always fresh.

[0036] like Figures 1 to 2 As shown, a pair of position-limiting clamping mechanisms 2 are respectively assembled on the outside of a pair of ventilation pipe openings 102. The position-limiting clamping mechanisms 2 include a pair of fixing frames 201, each of which is fitted on the outside of the ventilation pipe openings 102. The pair of fixing frames 201 facilitate the position-limiting clamping of the ventilation pipe openings 102 and the telescopic hose 103, thereby making the connection between the ventilation pipe openings 102 and the telescopic hose 103 more secure.

[0037] like Figure 2 As shown, a pair of fixing frames 201 are both threadedly connected with threaded rods 202. It is convenient to clamp the interface of the ventilation pipe opening 102 and the telescopic hose 103 through the pair of threaded rods 202, so that the connection between the ventilation pipe opening 102 and the telescopic hose 103 is more stable.

[0038] like Figures 1 to 4 As shown, one end of a pair of threaded rods 202 located in the fixing frame 201 is rotatably connected to an arc-shaped clamping block 203, and the side of the pair of arc-shaped clamping blocks 203 away from the threaded rods 202 is pressed against the outside of the ventilation pipe opening 102. By rotatably connecting the arc-shaped clamping blocks 203 to the ends of the threaded rods 202, and cutting a groove on the side of the arc-shaped clamping blocks 203 near the ventilation pipe opening 102 to cooperate with the ventilation pipe opening 102 and the telescopic hose 103, the arc-shaped clamping blocks 203 can be used to limit and clamp the interface between the ventilation pipe opening 102 and the telescopic hose 103, thereby making the connection between the ventilation pipe opening 102 and the telescopic hose 103 more stable.

[0039] like Figures 1 to 5 As shown, a pair of arc-shaped clamping blocks 203 are fitted with mating clamping blocks 204 on both sides, and multiple sets of mating clamping blocks 204 are mated with the ventilation pipe opening 102. By mating the mating clamping blocks 204 on both sides of the pair of arc-shaped clamping blocks 203, and by having grooves on one end of the multiple sets of mating clamping blocks 204 near the ventilation pipe opening 102 and the telescopic hose 103 that are mated with the ventilation pipe opening 102 and the telescopic hose 103, it is convenient to clamp and restrict the interface between the ventilation pipe opening 102 and the telescopic hose 103 through the multiple sets of mating clamping blocks 204 and the arc-shaped clamping blocks 203.

[0040] like Figures 2 to 5As shown, the multiple sets of matching blocks 204 are fixedly connected to a telescopic rod 205 on the side away from the ventilation pipe opening 102. The telescopic ends of the multiple sets of telescopic rods 205 are respectively fixedly connected to the multiple sets of matching blocks 204, and the fixed ends of the multiple sets of telescopic rods 205 are fixedly connected to the fixed frame 201. By fixing the multiple sets of matching blocks 204 to the telescopic ends of the telescopic rods 205, when the arc-shaped block 203 is used to adjust a pair of matching blocks 204 to move closer to the ventilation pipe opening 102, the telescopic rods 205 cooperate with the multiple sets of matching blocks 204 to move closer to the ventilation pipe opening 102, thereby facilitating the multiple sets of telescopic rods 205 and the multiple sets of matching blocks 204 to tighten and limit the ventilation pipe opening 102 and the telescopic hose 103.

[0041] like Figures 2 to 3 As shown, a pair of clips 206 are fixedly mounted on the outside of the pair of fixing frames 201, and a snap ring 207 is rotatably mounted inside the pair of clips 206. By installing the clips 206 on the outside of the pair of fixing frames 201, the pair of fixing frames 201 are locked to the outside of the ventilation pipe opening 102 and the telescopic hose 103 through the clips 206, thereby facilitating the stable insertion of the pair of fixing frames 201 on the outside of the ventilation pipe opening 102 and the telescopic hose 103, thereby stably connecting the ventilation pipe opening 102 and the telescopic hose 103.

[0042] like Figures 2 to 3 As shown, a pair of snap rings 207 are rotatably connected to a wrench 208 at one end away from the buckle 206. The pair of wrenches 208 are both hingedly connected to the side of the fixing frame 201 close to the buckle 206. The arrangement of the wrench 208 facilitates the adjustment of the wrench 208 on the side of the fixing frame 201 so that the snap ring 207 on the side of the wrench 208 engages and locks with the pair of buckles 206 on the outside of the adjacent fixing frame 201, thereby facilitating the fixed sleeve of the pair of fixing frames 201 on the outside of the ventilation pipe opening 102 and the telescopic hose 103.

[0043] like Figures 1 to 2 As shown, the air leakage warning mechanism 3 is fixedly mounted on the side of the fixing frame 201 and includes an air inlet pipe 301 that passes through the fixing frame 201. Due to the provision of the air inlet pipe 301, when an air leak occurs between the ventilation pipe opening 102 and the telescopic hose 103, the gas enters the air inlet pipe 301 through the fixing frame 201, thereby facilitating the air inlet pipe 301 to alert personnel to repair the pipeline.

[0044] like Figures 5 and 6As shown, the end of the air inlet pipe 301 away from the fixing frame 201 is connected to the speaker box 302, and multiple sets of ringing balls 303 are placed in the speaker box 302. By connecting the speaker box 302 and the air inlet pipe 301, air enters the speaker box 302 through the air inlet pipe 301. The air entering the speaker box 302 blows the multiple sets of ringing balls 303 inside the speaker box 302, thereby making a sound to remind staff to repair the air leak.

[0045] like Figures 5 and 6 As shown, an isolation net 304 is fixedly connected to one end of the air inlet pipe 301 near the loudspeaker box 302. The isolation net 304 allows the multiple sets of rattle balls 303 to be confined within the loudspeaker box 302. When air is introduced into the loudspeaker box 302 through the air inlet pipe 301, the gas blows the multiple sets of rattle balls 303 to jump inside the loudspeaker box 302, thereby making sounds to remind the staff to repair the pipeline in time.

[0046] like Figures 7 and 8 As shown, one end of a pair of threaded rods 202 located within the fixing frame 201 is threadedly connected to an adjustment plate 305. The pair of adjustment plates 305 are arranged between the fixing frame 201 and the arc-shaped block 203, and the adjustment plates 305 are arranged throughout the fixing frame 201. The arrangement of the adjustment plates 305 facilitates adjustment of the pair of adjustment plates 305 by the threaded rods 202 to move closer to the ventilation pipe opening 102 and the telescopic hose 103, so that the pair of adjustment plates 305 press against the outer sides of the ventilation pipe opening 102 and the telescopic hose 103 to limit the position, thereby reducing the relative vibration between the ventilation pipe opening 102 and the telescopic hose 103.

[0047] like Figures 7 and 8 As shown, a pair of balancing springs 306 are fixedly connected to both ends of the pair of adjustment plates 305 located outside the fixing frame 201. The balancing springs 306 are symmetrically distributed on both sides of the fixing frame 201. By fixing the balancing springs 306 on both sides of the pair of adjustment plates 305 and placing the balancing springs 306 against the outside of the ventilation pipe opening 102 and the telescopic hose 103, the balancing springs 306 can reduce the positional movement between the ventilation pipe opening 102 and the telescopic hose 103.

[0048] like Figures 7 and 8 As shown, the ends of the balance springs 306 away from the adjustment plate 305 are fixedly connected to a pressing block 307. The pair of pressing blocks 307 respectively cooperate with the ventilation pipe opening 102 and the telescopic hose 103. By disposing the pressing blocks 307, the pair of pressing blocks 307 are pressed against the outside of the ventilation pipe opening 102 and the telescopic hose 103, respectively, so that the pair of pressing blocks 307 can reduce the relative movement between the ventilation pipe opening 102 and the telescopic hose 103.

[0049] Specifically, by pressing a pair of pressing blocks 307 against the outside of the ventilation pipe opening 102 and the telescopic hose 103 respectively, when the relative position between the ventilation pipe opening 102 and the telescopic hose 103 moves, a pair of balancing springs 306 will contract or expand in coordination with the position movement of the ventilation pipe opening 102 and the telescopic hose 103, thereby slowing down the relative position movement between the ventilation pipe opening 102 and the telescopic hose 103.

[0050] like Figure 7 As shown, both sides of the pair of pressing blocks 307 are connected with a fitting plate 308. By fitting the fitting plates 308 on both sides of the pair of pressing blocks 307, it is convenient to adjust the pair of fitting plates 308 to press against the outside of the ventilation pipe opening 102 and the telescopic hose 103 through the pair of pressing blocks 307, thereby reducing the relative movement between the ventilation pipe opening 102 and the telescopic hose 103.

[0051] like Figure 7 As shown, a pair of bonding plates 308 are fixedly connected to a matching spring 309 on one side away from the ventilation pipe opening 102. The matching spring 309 facilitates the matching spring 309 and the bonding plates 308 to define the position of the ventilation pipe opening 102 and the telescopic hose 103, thereby ensuring a stable connection between the ventilation pipe opening 102 and the telescopic hose 103.

[0052] Specifically, the elastic coefficient of the fitting plate 308 is greater than the elastic coefficient of the matching spring 309 , thereby facilitating the fitting plate 308 to move closer to the ventilation pipe opening 102 and the telescopic hose 103 by adjusting the pressing block 307 .

[0053] like Figure 7 As shown, the end of the mating spring 309 away from the laminating plate 308 is fixedly connected to a receiving plate 310, which is fixedly connected to the side of the fixing frame 201. The provision of the receiving plate 310 facilitates the fixed connection of multiple sets of mating springs 309 to the receiving plate 310, so that the receiving plate 310 adjusts the multiple sets of mating springs 309 to tighten the ventilation pipe opening 102 and the telescopic hose 103.

[0054] like Figures 1 to 2 As shown, elastic sealing rings 311 are fixedly connected to both sides of the fixing frame 201, and a pair of abutting blocks 307 and abutting plates 308 are both assembled in the elastic sealing rings 311. The provision of the elastic sealing rings 311 facilitates the elastic sealing rings 311 to abut and limit the outer sides of the ventilation pipe opening 102 and the telescopic hose 103, thereby slowing down the relative movement between the ventilation pipe opening 102 and the telescopic hose 103. At the same time, the provision of the elastic sealing rings 311 can absorb the noise generated during the operation of the ventilation pipe opening 102 and the telescopic hose 103, thereby improving the performance of the fresh air device 1.

[0055] Preferably, the elastic sealing ring 311 can be made of bubble-proof cotton, which has high shock absorption, sound insulation and sealing properties.

[0056] During specific use, when fresh air ventilation is carried out for the smart building through the fresh air equipment 1, the ventilation pipe opening 102 is fixedly connected to the interface at the end of the telescopic hose 103, and the sealing strip at the interface of the ventilation pipe opening 102 and the telescopic hose 103 is sealed. Then, the arc-shaped block 203 on a pair of fixing frames 201 is matched with the interface between the ventilation pipe opening 102 and the telescopic hose 103, and the pair of fixing frames 201 are sleeved on the outside of the ventilation pipe opening 102 and the telescopic hose 103, and the wrench 208 on the outside of the fixing frame 201 is adjusted to rotate the wrench 208 adjustment ring 207, so that the clamping ring 207 is locked with a pair of buckles 206 on the outside of the adjacent fixing frame 201, so that the pair of fixing frames 201 are fixedly sleeved on the outside of the ventilation pipe opening 102 and the telescopic hose 103.

[0057] Subsequently, the threaded rod 202 is adjusted to rotate within the fixing frame 201, causing the threaded rod 202 to adjust the arc-shaped clamping block 203 to move closer to the interface between the ventilation pipe opening 102 and the telescopic hose 103, so that the arc-shaped clamping block 203 is pressed against the outside of the ventilation pipe opening 102 and the telescopic hose 103. At the same time, as the arc-shaped clamping block 203 moves closer to the ventilation pipe opening 102 and the telescopic hose 103, the mating clamping blocks 204 on both sides of the arc-shaped clamping block 203 cooperate with the arc-shaped clamping block 203 to press against the outside of the ventilation pipe opening 102 and the telescopic hose 103, and the telescopic end of the telescopic rod 205 cooperates with the mating clamping block 204 to move closer to the ventilation pipe opening 102 and the telescopic hose 103.

[0058] When the adjusting threaded rod 202 moves toward the ventilation pipe opening 102 and the telescopic hose 103, a pair of tightening blocks 307 cooperate with multiple sets of fitting plates 308 to stick to the outside of the ventilation pipe opening 102 and the telescopic hose 103. When the threaded rod 202 is rotated to adjust the adjusting plate 305 to move toward the ventilation pipe opening 102, a pair of balancing springs 306 are compressed, and multiple sets of matching springs 309 are in a stretched state due to the force of the tightening block 307 moving toward the ventilation pipe opening 102.

[0059] When shaking occurs between the ventilation pipe opening 102 and the telescopic hose 103, multiple groups of balance springs 306 cooperate with multiple groups of matching springs 309 to expand or contract. When a crack occurs between the ventilation pipe opening 102 and the telescopic hose 103 and air leaks, gas enters the loudspeaker box 302 through the air inlet pipe 301. The gas blows the multiple groups of ringing balls 303 in the loudspeaker box 302 to jump, causing the ringing balls 303 to make a sound in the loudspeaker box 302, thereby prompting the staff to repair the leaking pipe.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
