Description

Technical Field

[0001] The utility model relates to a ventilation device, in particular to an intelligent building ventilation device. Background Art

[0002] The building ventilation device is a very important device in a building. It has the functions of heating and cooling the building, humidifying and dehumidifying, and removing dust.

[0003] The most common dust removal device on the market is the cyclone dust collector, which is generally driven by a motor and mainly relies on the centrifugal force generated by the movement of air in the dust collector and the downward thrust of the air to remove dust. This will result in a smaller centrifugal force in the middle part of the dust collector, and there is still a lot of dust in the exhausted air. In addition, if the power of the motor used is too large, the noise will also be very loud. Utility Model Content

[0004] The utility model aims to provide an intelligent building ventilation device to solve the problems of unclean dust removal and high noise raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An intelligent building ventilation device comprises a bracket, a dust removal component and a bottom plate mounted on the bracket, and a power mechanism is mounted on the bottom plate;

[0007] The dust removal assembly includes a dust removal bucket fixed to the bracket and a pump air assembly connected to the dust removal bucket, and the pump air assembly is connected to the power mechanism;

[0008] It also includes an acceleration mechanism, which is installed in the dust removal barrel and connected to the power mechanism through a transmission member. The acceleration mechanism includes a spiral barrel rotatably installed in the dust removal barrel, the spiral barrel is hollow and connected to the exhaust port of the dust removal barrel, and a spiral blade is fixed on the spiral barrel.

[0009] The intelligent building ventilation device as described above: the power mechanism comprises a motor fixedly connected to the base plate;

[0010] The motor output shaft is connected to the pump air component.

[0011] The intelligent building ventilation device as described above: the pump air assembly includes a fan connected to the motor output shaft and a pipe having one end fixedly connected to the fan air outlet;

[0012] The other end of the pipeline is communicated with the dust removal bucket.

[0013] The intelligent building ventilation device as described above: the transmission member comprises a first driven rod rotatably connected to the base plate and a second driven rod rotatably connected to the first driven rod at one end through a bevel gear;

[0014] A first driven gear is fixedly mounted on one end of the first driven rod close to the fan, and the first driven gear is meshed with a driving gear fixedly mounted on the output shaft of the motor. The second driven rod is rotationally connected to the base plate and the dust collection barrel, and a second driven gear is fixedly mounted on the other end of the second driven rod, and the second driven gear is meshed with a third driven gear fixed on the spiral cylinder.

[0015] The intelligent building ventilation device as described above: an air inlet is opened in the tangential direction of the dust removal barrel, and the air inlet is connected to the pipeline.

[0016] The intelligent building ventilation device as described above: a dust storage box is installed at the bottom of the dust removal barrel, and the dust storage box can be slid and pulled away from the dust removal barrel.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: the air inlet of the pump air component in the device is connected to the indoor environment, and the air outlet is connected to the dust removal bucket. When the power mechanism is working, it drives the pump air component to pump the indoor air into the dust removal bucket, and the suspended particles in the air approach the edge of the dust removal bucket under the action of centrifugal force; as the air is continuously pumped in, the air behind has a downward thrust on the air in front, so that the suspended particles in the air eventually fall to the bottom of the dust removal bucket, and the dust-removed air is discharged from the dust removal bucket through the spiral drum.

[0018] When the power mechanism drives the pump air component to work, it also drives the acceleration mechanism to rotate, that is, the spiral barrel and the spiral blades rotate, thereby increasing the air movement speed in the dust removal barrel, causing the suspended particles to be subjected to greater centrifugal force. At the same time, the spiral blades give the air a downward thrust, making the dust removal effect of the device more efficient and obvious, and enabling the device to achieve the dust removal effect of a high-power motor under the action of a low-power motor, reducing noise and energy consumption during use.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1 to Figure 6 As an embodiment of the utility model, the intelligent building ventilation device comprises a bracket 1 and a dust removal component and a bottom plate 2 mounted on the bracket 1, and a power mechanism is mounted on the bottom plate 2;

[0028] The dust removal assembly includes a dust removal bucket 3 fixed to the bracket 1 and a pump air assembly connected to the dust removal bucket 3, and the pump air assembly is connected to the power mechanism;

[0029] It also includes an acceleration mechanism, which is installed in the dust removal bucket 3 and is connected to the power mechanism through a transmission member. The acceleration mechanism includes a spiral barrel 16 rotatably installed in the dust removal bucket 3. The spiral barrel 16 is hollow and connected to the exhaust port of the dust removal bucket 3. A spiral blade 17 is fixed on the spiral barrel 16.

[0030] In this embodiment, the device has the function of indoor ventilation and can remove suspended particles in the air to a certain extent during the ventilation process, and then discharge the cleaned air to the outdoors; the specific plan is as follows: the air inlet of the pump air component in the device is connected to the indoor room, and the air outlet is connected to the dust removal bucket 3. When the power mechanism is working, it drives the pump air component to work and pumps the indoor air into the dust removal bucket 3. The suspended particles in the air approach the edge of the dust removal bucket 3 under the action of centrifugal force; as the air is continuously pumped in, the air behind has a downward thrust on the air in front, so that the suspended particles in the air eventually fall to the bottom of the dust removal bucket 3, and the dust-removed air is discharged from the dust removal bucket 3 through the spiral cylinder 16.

[0031] When the power mechanism drives the pump air component to work, it also drives the acceleration mechanism to rotate, that is, the spiral barrel 16 and the spiral blade 17 rotate, thereby increasing the air movement speed in the dust removal barrel 3, so that the suspended particles are subjected to a greater centrifugal force. At the same time, the spiral blade 17 gives the air a downward thrust, making the dust removal effect of the device more efficient and obvious, and enabling the device to achieve the dust removal effect of a high-power motor under the action of a low-power motor, reducing noise and energy consumption during use.

[0032] As a further solution of the utility model, the power mechanism includes a motor 5 fixedly connected to the base plate 2; the output shaft of the motor 5 is connected to the pump air component.

[0033] In this embodiment, the motor 5 drives the air pump assembly to pump air into the dust bucket 3. After the air enters the dust bucket 3, it has a certain speed. The suspended particles in the air stick to the inner wall of the dust bucket 3 under the action of centrifugal force. The air behind squeezes the air in front downward, and finally the suspended particles are discharged from the dust bucket 3.

[0034] As a further solution of the utility model, the pump air assembly includes a fan 6 connected to the output shaft of the motor 5 and a pipe 7 with one end fixedly connected to the air outlet of the fan 6;

[0035] The other end of the pipeline 7 is connected to the dust removal barrel 3.

[0036] In this embodiment, the air inlet of the fan 6 is connected to the indoor room, and the air outlet is connected to the dust removal bucket 3 through the pipe 7; the motor 5 drives the fan 6 to work, and the fan 6 pumps the indoor air into the dust removal bucket 3 through the pipe 7.

[0037] The inner side of the dust removal barrel 3 is cylindrical on the top and conical on the bottom, with an exhaust port on the top and a dust exhaust port on the bottom; when air enters the dust removal barrel 3, the suspended particles move downward along the inner wall of the dust removal barrel 3 under the action of centrifugal force, gravity, and the thrust of the gas behind, and are finally discharged from the dust exhaust port at the bottom, and the dust-removed air is discharged through the exhaust hole on the top.

[0038] As a further solution of the utility model, the transmission member includes a first driven rod 11 rotatably connected to the base plate 2 and a second driven rod 13 rotatably connected to the first driven rod 11 through a bevel gear 12 at one end;

[0039] A first driven gear 10 is fixedly mounted on one end of the first driven rod 11 close to the fan 6, and the first driven gear 10 is meshed with a driving gear 9 fixedly mounted on the output shaft of the motor 5. The second driven rod 13 is rotationally connected to the base plate 2 and the dust removal barrel 3, and a second driven gear 14 is fixedly mounted on the other end of the second driven rod 13, and the second driven gear 14 is meshed with a third driven gear 15 fixed on the spiral cylinder 16.

[0040] In this embodiment, the motor 5 drives the driving gear 9 to rotate, and then drives the first driven gear 10 to rotate, that is, the first driven rod 10 rotates, the first driven rod 10 drives the bevel gear 12, that is, the second driven rod 13 rotates, the second driven gear 14 rotates with the second driven rod 13, the second driven gear 14 drives the third driven gear 15 to rotate, and finally drives the spiral cylinder 16 to rotate.

[0041] The rotation of the spiral drum 16 drives the spiral blades 17 to rotate, thereby accelerating the movement speed of air in the dust removal barrel 3, thereby subjecting the suspended particles to a greater centrifugal force, reducing the content of suspended particles in the air discharged from the dust removal barrel 3; the rotation of the spiral blades 17 gives the air a downward thrust, making the dust removal faster and more efficient.

[0042] As a further solution of the utility model, an air inlet 8 is opened in the tangential direction of the dust removal barrel 3 , and the air inlet 8 is connected to the pipeline 7 .

[0043] In this embodiment, an air inlet 8 is provided in the tangential direction of the dust bucket 3 so that the air can enter the dust bucket 3 faster and with greater centrifugal force, thereby increasing the adhesion of suspended particles to the inner wall of the dust bucket 3, reducing the content of suspended particles in the exhaust gas and achieving a more significant dust removal effect.

[0044] As a further solution of the utility model, a dust storage box 4 is installed at the bottom of the dust removal barrel 3, and the dust storage box 4 can be slidably pulled away from the dust removal barrel 3.

[0045] In this embodiment, the dust box 4 is used to store the suspended particles separated from the air. When you want to clean the dust box 4, you only need to pull out the dust box 4 and dump the suspended particles. The sliding and pulling design makes dumping the suspended particles more convenient and quick, and has a better sealing effect.

[0046] As a further solution of the utility model, the device is also equipped with a suspended particle detector, and the suspended particle detector and the motor 5 are both controlled by a PLC controller.

[0047] In this embodiment, when the suspended particle detector detects that the content of suspended particles in the indoor air exceeds the standard, it feeds back information to the PLC controller, and the PLC controller controls the motor 5 to work. When the content of suspended particles in the indoor air drops to a certain value, the PLC controller controls the motor 5 to stop working.

[0048] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
