Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exhaust devices, in particular to an independent air supply device for a clean room. Background Art
[0002] Clean rooms have high requirements for air quality. Existing indoor air supply devices are mostly exhaust fans and their components. At the same time, the exhaust duct is not equipped with a corresponding pipe baffle except for a filter. When the exhaust fan stops working, outside air can still enter the room through the gap of the exhaust fan. If the air carries impurities that cannot be filtered by the filter and enters the room, and the exhaust fan is not started, the indoor air cannot be discharged in time, which will have a great impact on the indoor air quality.

DETAILED DESCRIPTION
[0017] 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.
[0018] Reference Figure 1-Figure 3, an independent air supply device for a clean room, comprising a ventilation duct 1, which is arranged in a vertical flat-mouth shape, a horizontal partition 2 is fixedly arranged in the middle of the ventilation duct 1, a bracket 3 and a bracket 4 are fixedly arranged on the upper side wall and the lower side wall of the partition 2, respectively, a motor 5 and a motor 6 are fixedly inserted on the bracket 3 and the bracket 4, respectively, the driving ends of the motor 5 and the motor 6 are both arranged horizontally forward, when power is turned on, the driving end of the motor 5 rotates in the opposite direction relative to the motor 6, the driving ends of the motor 5 and the motor 6 are respectively fixedly sleeved with an exhaust fan 7 and an exhaust fan 8, the exhaust fan 7 and the exhaust fan 8 rotate in the opposite direction, when the exhaust fan 7 sucks the outside air into the ventilation duct 1 and discharges it to the room, the exhaust fan 2 8 sucks the indoor air into the ventilation duct 1 and discharges it to the outside, so that the indoor air is circulated.
[0019] A limiting ring 19 located at the rear side of the bracket 13 is fixedly arranged between the partition 2 and the upper inner wall of the ventilation duct 1, a limiting ring 2 10 located at the rear side of the bracket 2 4 is fixedly arranged between the partition 2 and the lower inner wall of the ventilation duct 1, and a fixed axis located at the upper and lower sides of the partition 2 is fixedly arranged on the inner wall of the ventilation duct 1, and the two fixed axes are close to the partition 2 and symmetrical about the partition 2, and the outer walls of the two fixed axes are respectively movably sleeved with a baffle 11 and a baffle 2 12, and the baffle 1 11 and the baffle 2 12 are respectively located at the rear sides of the limiting ring 1 9 and the limiting ring 2 10. After the baffle 1 11 and the baffle 2 12 are respectively turned over to fit with the limiting ring 1 9 and the limiting ring 2 10, the outer walls of the baffle 1 11 and the baffle 2 12 are respectively matched and engaged with the inner wall of the ventilation duct 1.
[0020] A magnet block 13 and a magnet block 14 are fixedly arranged in the middle of the rear side wall of the baffle plate 11 and the baffle plate 2 12 respectively. After the baffle plate 11 and the baffle plate 2 12 are turned over to the horizontal, the opposite magnetic poles of the magnet block 13 and the magnet block 2 14 are opposite. The outer side of the baffle plate 11 and the baffle plate 2 12 is provided with an anti-skid pad, and the anti-skid pad is elastic. Through the extrusion and filling of the anti-skid pad, the baffle plate 11 and the baffle plate 2 12 after being attached to the limiting ring 1 9 and the limiting ring 2 10 are kept relatively fixed to the ventilation pipe 1. The rear of the baffle plate 11 and the baffle plate 2 12 The side walls are provided with handles 15, and the middle part of the handles 15 does not extend backward beyond the rear side walls of the magnet block 13 and the magnet block 2 14. Before starting the motor 1 5 and the motor 2 6, the baffle 1 11 and the baffle 2 12 are flipped to be horizontal. At this time, the magnet block 13 and the magnet block 2 14 are attracted to each other, so that the baffle 1 11 and the baffle 2 12 remain horizontally fixed. At the same time, due to the horizontal separation of the baffle 1 11 and the baffle 2 12, the air exhausted by the exhaust fan 1 7 will not be immediately exhausted by the exhaust fan 2 8, thereby ensuring the circulation efficiency of the indoor air to a certain extent.
[0021] The outer wall of the ventilation duct 1 is fixedly sleeved with a positioning ring 16, which is close to the front end of the ventilation duct 1. The outer wall of the positioning ring 16 is provided with a plurality of positioning holes. When installing the ventilation duct 1, a notch matching the ventilation duct 1 is opened on the wall, and the ventilation duct 1 is inserted into the notch from the outside of the wall so that the positioning ring 16 is pressed against the outer wall of the wall, and the positioning ring 16 is fixed to the wall by bolts to fix the ventilation duct 1.
[0022] A fixing ring 17 is fixedly provided on the front side wall of the ventilation duct 1, and a filter 18 is provided on the fixing ring 17. The filter 18 is used to filter impurities such as dust in the air. When the baffle 1 11 and the baffle 2 12 in the utility model are flipped to a horizontal position and fixed, the air is discharged into the room from the upper side of the baffle 11, and then the indoor air is discharged from the ventilation duct 1 from the lower side of the baffle 2 12, which is beneficial to maintaining the indoor air circulation efficiency. When the baffle 1 11 and the baffle 2 12 are flipped to engage with the ventilation duct 1, it is ensured that when the motor 1 5 and the motor 2 6 stop working, the outside air cannot enter the room through the ventilation duct 1, and the indoor air quality is maintained.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
