Detailed Description
The utility model provides a mute anti-upwind ventilator, which solves the problem of poor anti-upwind performance in the prior art.
In order that the above-described aspects may be better understood, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.
Examples:
the utility model provides a mute anti-upwind ventilator which comprises an air duct 1, an air inlet shell 2, an air outlet shell 3, a ventilation mechanism 4 and a fan control mechanism 5. The two ends of the air duct 1 are respectively connected with the air inlet shell 2 and the air outlet shell 3. The ventilation mechanism 4 is connected with the inner wall of the air duct 1. The air inlet shell 2 and the air outlet shell 3 are provided with the air control mechanism 5 at the opening.
The air duct 1 comprises an air duct shell 11 and two air opening matrixes 12. The two tuyere base bodies 12 are respectively connected with two ends of the air duct shell 11. The air duct shell 11 is connected with the air exchanging mechanism 4 through a connecting frame 13. The air inlet shell 2 and the air outlet shell 3 are respectively detachably connected with the air outlet base body 12.
In this embodiment, the air inlet housing 2 and the air outlet housing 3 may be connected to the air inlet base 12 by bolts. The air inlet shell 2 and the air outlet shell 3 are connected to the air inlet base 12. The staff can conveniently disassemble and maintain the whole body.
Further, the ventilation mechanism 4 includes a fan 41 and a fan motor 43. The fan motor 43 is connected with the connecting frame 13, and the driving end of the fan motor 43 penetrates through the connecting frame 13 to be connected with the fan 41.
The ventilation mechanism 4 further comprises a ratchet 42. The ratchet wheel 42 is provided with a plurality of ratchet wheel fixing holes 411, and the ratchet wheel fixing holes 411 are connected with the fan 41 through bolts. The ratchet wheel 42 is provided with a shaft hole. The driving end of the fan motor 43 is connected to the fan 41 through the shaft hole of the ratchet wheel 42. The connecting frame 13 is provided with a stop mechanism 131, and the stop mechanism 131 is matched with the ratchet wheel 42.
When the outdoor wind is large, the upwind causes the fan 41 to reverse. The stopping mechanism 131 cooperates with the ratchet wheel 42, and when the ratchet wheel 42 follows the fan 41 to generate reverse force, the stopping mechanism 131 catches the ratchet wheel 42, so that the fan 41 is not affected by the upwind. The stop mechanism 131 may be a stop tab or a stop ratchet. The locking mechanism 131 is matched with the ratchet wheel 42, so that the fan 41 can continue to normally operate or even stop by braking of the locking mechanism 131 when outdoor wind power is high. At this time, the fan 41 increases wind resistance, reduces air flow, and reduces the loss of indoor heat due to air convection.
Further, the air control mechanism 5 includes a plurality of louvers 51, a micro motor 52, and a rack 53. The air inlet shell 2 and the air outlet shell 3 are respectively provided with a mounting groove. The micro motor 52 and the rack 53 are both disposed in the mounting groove. The micro motor 52 is connected to the rack 53 via a motor gear 54. The vane 51 is connected to the rack 53 by a vane gear 55.
The air inlet shell 2 and the air outlet shell 3 are respectively provided with a mounting groove, and the size of each mounting groove is enough for the rack 53 to move up and down. Wherein, the rack 53 and the inner side wall of the installation groove can be in sliding connection. The micro motor 52 drives the motor gear 54, so that the rack 53 moves up and down, and when the rack 53 moves up and down, the window She Chilun 55 is driven to rotate, so as to drive the window vane 51 coaxially connected with the window She Chilun 55, so as to achieve the effect of opening and closing a plurality of window vanes 51. Prevent the entry of rainwater and upwind during severe weather.
Further, two ends of the through hole of the air duct shell 11 are connected with dustproof nets 6. And mute cotton is also arranged on the dustproof net 6.
The dust screen 6 prevents flying insects and particles from entering the room, and also prevents the operation of the fan motor 43 from being affected. Meanwhile, the noise generated in the dust screen 6 can be reduced by the mute cotton. Wherein, the dust screen 6 is detachably connected with the air duct shell 11. The air inlet shell 2 and the air outlet shell 3 are respectively detachably connected with the air outlet base body 12. When the dust screen 6 needs to be replaced, the replacement and maintenance can be performed only by disassembling the air inlet shell 2 and the air outlet shell 3.
Further, a buried wire box 7 is arranged on the outer side wall of the air duct shell 11. Wiring for the fan motor 41 and the micro motor 52 and other electrical control devices can be placed in the buried wire box 7.
Further, a vibration-proof layer 8 is provided between the fan motor 43 and the connection frame 13. The vibration-proof layer 8 may be made of a bubble structure type material such as rubber, foam, bubble plastic film, foam sheet, etc. In this embodiment, the vibration-proof layer 8 is made of rubber. The vibration-proof layer 8 can prevent resonance between the wind drum 1 and the fan motor 43, and reduce huge noise generated in the operation process of the fan motor 43. Loosening of the connection caused by vibration of the fan motor 43 is also avoided to some extent.
Working principle:
in normal operation, the micro motor 52 drives the window 51 through the rack 53, so that a plurality of window 51 reach a required opening and closing angle. The fan motor 43 drives the fan 41 to operate, thereby achieving the ventilation effect.
When the outdoor wind force is excessive and the reverse wind force is generated, the opening and closing angles of the plurality of louver blades 51 can be reduced by controlling the micro motor 52. The stop mechanism 131 prevents the fan 41 from reversing by catching the ratchet 42.
While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that alterations, modifications, substitutions and variations may be made in the above embodiments by those skilled in the art within the scope of the utility model.
