Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-9 of the drawings, the present invention provides a ventilation device for a flue of a building.
Referring to fig. 1-3, in this embodiment, the ventilation device for a flue of a building includes a main body mechanism 1, the main body mechanism 1 includes a pipe outer protecting shell 101, a plurality of brackets 102 are fixedly installed on top of the pipe outer protecting shell 101, a top cover 103 is fixedly installed on top of the plurality of brackets 102, and ventilation plates 104 are fixedly installed on outer walls of the plurality of brackets 102; in use, the flue gas via the duct outer shield 101 can be exhausted through the ventilation plate 104.
The top of the main body mechanism 1 is communicated with an exhaust mechanism 3, the exhaust mechanism 3 comprises an air duct 31 communicated with the top of a top cover 103, and a first fan 35 is rotatably arranged in the air duct 31; the inner cavity of the outer protecting shell 101 of the pipeline is provided with a built-in smoke pipe 105; under the condition that the outside has wind, when the first fan 35 is blown by wind to rotate, the ventilation speed of the top of the outer protecting shell 101 of the pipeline can be increased, so that the air pressure inside the outer protecting shell 101 of the pipeline is increased, the efficiency of absorbing the smoke in a building is further enhanced, the flow of the smoke is accelerated, and the ventilation of the smoke inside the flue is guaranteed. Alternatively, the connection between the outer protecting shell 101 and the inner smoke tube 105 is not fixed, and may be a connection mode of relative displacement, such as flexible connection, sliding connection, etc.
The first cleaning mechanism 4 is rotatably arranged in the inner cavity of the built-in smoke tube 105, and the first cleaning mechanism 4 comprises a first scraping plate 49; a double-shaft motor 36 which can drive the first fan 35 to rotate and simultaneously drive the first scraping plate 49 on the first cleaning mechanism 4 to rotate and intermittently attach to the inner wall surface of the built-in smoke tube 105 for oil stain scraping operation is arranged between the first cleaning mechanism 4 and the first fan 35 in the air drum 31.
When the smoke emission is not smooth enough, the first fan 35 can be rotated on the top of the outer protecting shell 101 by starting the double-shaft motor 36, so that the ventilation of the top of the outer protecting shell 101 can be accelerated. Meanwhile, the double-shaft motor 36 can drive the first scraping plate 49 on the first cleaning mechanism 4 to rotate and intermittently adhere to the inner wall surface of the built-in smoke tube 105 to conduct oil stain scraping operation, so that oil stain impurities in smoke are prevented from adhering to the inner wall of the built-in smoke tube 105, the ventilation tube diameter is reduced, the ventilation smoothness is affected, and the maintenance cost of the ventilation device is reduced. In addition, the dirt removing operation of the first scraping plate 49 is completed by intermittently attaching the first scraping plate to the inner wall surface of the built-in smoke tube 105, so that the situation that the scraping plate is stuck due to the fact that the scraping plate is solidified by greasy dirt due to long-term attaching of the smoke tube can be avoided, and the operation cannot be started normally.
In the above embodiment, the top cover 103 may be specifically designed as follows:
specifically, the top cover 103 is arranged in a circular arc shape, and the circular arc opening of the top cover 103 is arranged towards the direction of the pipeline outer protecting shell 101. The purpose of this arrangement is to enable the flue gas discharged through the upward extension of the inside of the outer protecting case 101 of the pipeline to be guided to the outer wall direction of the ventilation plate 104 when the flue gas collides with the inner wall of the top cover 103, so that the flue gas can be discharged in a dispersed and outward manner when the flue gas flows into the ventilation plate 104.
In the above embodiment, the air duct 31 may be specifically designed, as follows:
specifically, the air duct 31 extends into the ventilating plate 104, the air collecting baffle 32 is fixedly mounted at one end thereof, the first ventilating type supporting plate 33 is fixedly mounted at the communication position between the air collecting baffle 32 and the air duct 31, the second ventilating type supporting plate 34 is fixedly mounted on the inner wall of the air duct 31, the first fan 35 is rotatably mounted at one side of the second ventilating type supporting plate 34 away from the first ventilating type supporting plate 33, and the double-shaft motor 36 is positioned between the second ventilating type supporting plate 34 and the first ventilating type supporting plate 33.
It should be noted that, the connection manner between the dual-shaft motor 36 and the first cleaning mechanism 4 is not limited in the above embodiment, and any structure and connection manner are adopted, so long as the first cleaning mechanism 4 can rotate the first scraper 49 on the first cleaning mechanism 4 under the driving of the dual-shaft motor 36 and intermittently adhere to the inner wall surface of the built-in smoke tube 105 for performing the oil stain scraping operation, which is within the scope of the present invention. Of course, a connection between the biaxial motor 36 and the first cleaning mechanism 4 and a specific design of the first cleaning mechanism 4 can be specifically designed, see below:
specifically, the first cleaning mechanism 4 includes a first rotating shaft 41 fixedly connected to an end portion of an output shaft of the dual-shaft motor 36, a reciprocating screw 42 is fixedly connected to a bottom portion of the first rotating shaft 41, a threaded sleeve 43 is meshed with an outer wall of the reciprocating screw 42, a second rotating shaft 44 is fixedly connected to a bottom portion of the reciprocating screw 42, a sleeve 45 is rotatably installed on an outer wall of the second rotating shaft 44, a plurality of first supporting rods 48 are hinged to an outer wall of the sleeve 45, a first scraping plate 49 is hinged to one end of each of the plurality of first supporting rods 48, and a second supporting rod 410 is hinged between each of the first scraping plates 49 and the threaded sleeve 43.
When the reciprocating screw rod 42 is used, the thread sleeve 43 can be made to move up and down on the outer wall of the reciprocating screw rod 42, in a normal state, one side of the first supporting rod 48, which is close to the first scraping plate 49, is in an upward inclined state, the first scraping plate 49 is close to the outer wall of the sleeve 45, and when the thread sleeve 43 is continuously moved downwards, the second supporting rod 410 can be made to press the first supporting rod 48 downwards, so that the first supporting rod 48 is converted into a horizontal state from an inclined state, the first scraping plate 49 is attached to the inner wall of the built-in smoke tube 105, and then when the reciprocating screw rod 42 integrally rotates, the plurality of first scraping plates 49 are made to rotationally scrape greasy dirt impurities adhered to the inner wall of the built-in smoke tube 105.
It will be appreciated that, to keep the reciprocating screw 42 stably driving the first scraper 49 to rotate during rotation, a limiting mechanism may be specifically designed, as follows:
specifically, a limiting groove 46 is formed in the top of the sleeve 45, a limiting block 47 is fixedly arranged at the bottom of the threaded sleeve 43, and the limiting block 47 is inserted into the inner cavity of the limiting groove 46.
Further, the inner cavity of the limiting groove 46 may be provided with a clamp spring for limiting the limiting block 47, when the limiting block 47 moves up or down to the position of the clamp spring in the inner cavity of the limiting groove 46, the clamp spring limits the limiting block 47 to continue to longitudinally displace, at this time, the sleeve 45 rotates along with the reciprocating screw 42 until the clamp spring is deformed under force and cannot perform the limiting function, and the limiting block 47 continues to longitudinally displace.
Still further, the limiting block 47 may be provided with a clamping groove matched with the clamping spring, and when the limiting block 47 longitudinally displaces and the clamping spring is inserted into the clamping groove, the limiting groove 46 plays a limiting role on the threaded sleeve 43.
In the above embodiment, the threaded sleeve 43 may be further designed as follows:
specifically, the outer wall of the threaded sleeve 43 is in an annular shape, and a plurality of third supporting rods 411 are fixedly installed in an equidistant state in sequence, one ends of the third supporting rods 411 are fixedly installed with second scraping plates 412, and the second scraping plates 412 are in contact with the inner wall of the ventilation board 104. In the process that the screw sleeve 43 drives the second scraping plate 412 to move downwards integrally, the floating dust on the ventilation board 104 can be scraped, and the floating dust is prevented from blocking the air outlet of the ventilation board 104.
Furthermore, in the specific implementation, when the double-shaft motor 36 is started to enable the first fan 35 to rotate at the top of the outer protecting shell 101 of the pipeline, the main body mechanism 1 and the air suction mechanism 2 can be enabled to quickly suck air to accelerate the discharge of oil smoke, and meanwhile, when the first rotating shaft 41 is driven to enable the reciprocating screw rod 42 to rotate, the thread sleeve 43 is enabled to drive the second scraping plate 412 to integrally move downwards on the inner wall of the ventilating plate 104, so that floating dust on the inner wall of the ventilating plate 104 is scraped, and the air inlet and outlet efficiency of the ventilating plate 104 is prevented from being blocked by the floating dust. Meanwhile, when the threaded sleeve 43 continuously moves downwards to enable the second supporting rod 410 to push the first scraping plate 49 to be attached to the outer wall of the built-in smoke tube 105 until the threaded sleeve 43 moves to the top of the sleeve 45 and is temporarily limited in the sleeve, the threaded sleeve 43 which rotates synchronously with the reciprocating screw rod 42 can synchronously drive the plurality of first scraping plates 49 to be attached to the inner wall of the built-in smoke tube 105 for rotary scraping treatment, and further the problem that oil stains are attached to the inner wall of the built-in smoke tube 105, and the ventilation channel inner diameter of the oil stains is narrowed to influence the ventilation smoothness is avoided.

It will be appreciated that in the above embodiments, the dirt is removed by physical means, and therefore, a cleaning solution spraying mechanism can be specifically designed, as follows:
referring to fig. 6-7, specifically, at least two rubber air bags 106 are fixedly installed between the outer protecting shell 101 of the pipeline and the built-in smoke tube 105, the interiors of the two rubber air bags 106 are all communicated with a through pipe 107, and a plurality of spray holes 108 are formed in the interiors of the two rubber air bags 106;
the nozzle 108 formed in the interior of one rubber bladder 106 is disposed at the top thereof, and the nozzle 108 formed in the interior of the other rubber bladder 106 penetrates the bottom of the rubber bladder 106.

In the above embodiment, a second cleaning mechanism 5 may be specifically designed, as follows:
specifically, the second filter screen 27 is fixedly installed on the inner wall of the air suction cover 21, and the second filter screen 27 is used for filtering fine substances in the smoke again by the second filter screen 27 when the smoke is absorbed into the air suction cover 21, so that the impurity content in the smoke is removed again, and the impurity content in the smoke entering the inner cavity of the built-in smoke tube 105 is greatly reduced.

Secondly, the rotatable first fan 35 is arranged at the top of the pipeline outer protective shell 101, and the second fan 55 coaxial with the first fan 35 is arranged at the bottom of the pipeline outer protective shell 101, so that the air circulation speed at the top air outlet of the pipeline outer protective shell 101 and the air suction mechanism 2 arranged at the bottom of the pipeline outer protective shell 101 is increased under the condition that the whole smoke is not smooth, and the whole ventilation and air exhaust effects of the invention are further enhanced.
In addition, the inner cavity of the pipeline outer protective shell 101 is provided with the built-in smoke pipe 105 capable of moving back and forth, so that in the ventilation process, on one hand, the first filter screen 23 can be displaced at the bottom of the pipeline outer protective shell 101, the air suction range of the first filter screen 23 is enlarged, the smoke ventilation efficiency is improved, on the other hand, the built-in smoke pipe 105 is kept in a movable state, and when the built-in smoke pipe 105 is subjected to ventilation treatment, the built-in smoke pipe 105 can always keep a back and forth shaking state, and further the problem that oil stains are always static and extremely easy to adhere to the inner wall of the built-in smoke pipe and are inconvenient to clean is avoided.
Finally, according to the invention, the rubber air bag 106 for containing the cleaning agent is arranged between the pipeline outer protecting shell 101 and the built-in smoke tube 105, so that the built-in smoke tube 105 moves to press the rubber air bag 106 against the surface of the second filter screen 27 in the process of the inner cavity of the pipeline outer protecting shell 101, and further, adhered greasy dirt is effectively dissolved, and then, the greasy dirt can be cleaned better when the rotary scraping treatment of the first cleaning mechanism 4 and the second cleaning mechanism 5 is combined.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
