Description

Technical Field

[0001] The invention relates to the technical field of roof ventilators, in particular to a roof ventilator with filtering and purification functions. Background Art

[0002] Roof ventilators are also called roof natural ventilators, roof natural ventilators, etc. Roof ventilators are divided into strip roof ventilators and spherical roof ventilators. Strip roof ventilators are divided into streamlined roof ventilators and thin roof ventilators. The snow load capacity of roof ventilators depends on factors such as the design form of the steel frame, the material specifications of the steel frame, and the thickness of the rain shield. The selection of component material specifications is very important. First of all, it should fully ensure that the wind and snow load requirements are met to solve indoor ventilation, lighting, smoke exhaust and other needs. At the same time, it is also necessary to avoid unnecessary selection of oversized specifications. Spherical roof ventilators can pass through indoor and outdoor The rising airflow formed by the temperature difference is ejected and rotated under the guidance of the arc blades, thereby further attracting the indoor air to be discharged. Since the spherical roof ventilation needs to take into account its rainproof performance, the spacing between the arc blades is small, so that in the case of natural wind, the air intake is small, and dust may be brought in when the air is taken in. In addition, the existing spherical roof ventilator rotates by natural wind, but in the case of strong wind, the spherical roof ventilator may generate a large noise due to the excessive speed, and the excessive speed may also easily cause the spherical roof ventilator to malfunction;

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 11 , an embodiment of the present invention: a roof ventilator with filtering and purifying function, comprising a mounting disc 1, two groups of mounting discs 1, an array of arc blades 2 is arranged between the two groups of mounting discs 1, the lower mounting disc 1 is rotatably mounted on a fixed cylinder 3, a mounting ring 4 is arranged on the fixed cylinder 3, a rotating rod 5 is fixedly mounted on the arc blade 2, the rotating rod 5 is rotatably mounted between the mounting discs 1, a mounting frame 6 is fixedly mounted in the lower mounting disc 1 and the fixed cylinder 3, a rotating motor 9 is fixedly mounted on the upper mounting frame 6, a double-headed motor 7 is fixedly mounted on the lower mounting frame 6, and a dust adsorption block 8 is arranged on the output shaft at the lower side of the double-headed motor 7;

[0035] An adjusting mechanism, the adjusting mechanism is arranged at the rotating motor 9, and the adjusting mechanism is used to adjust the opening angle of the arc-shaped blade 2;

[0036] A filter mechanism, which is arranged on the arc-shaped blade 2 and is used to filter the air entering the fixed cylinder 3;

[0037] The locking mechanism is arranged at the mounting frame 6, and is used to lock the double-headed motor 7 and the mounting disc 1. The device controls the gap between the arc-shaped blades 2 through the adjustment mechanism, so that not only the air intake of the device can be adjusted, but also the windward angle of the arc-shaped blades 2 can be adjusted. In addition, a filtering mechanism is provided, so that some larger dust or impurities can be blocked by the filtering mechanism, thereby achieving the ability to purify the air;

[0038] Furthermore, the adjustment mechanism includes a gear ring 10, which is fixedly mounted on the output shaft of the rotating motor 9. The upper end of the rotating rod 5 is provided with tooth grooves 11 in an array, and the teeth of the gear ring 10 are engaged in the rotating rod 5. This structure allows the arc blades 2 to be unfolded and closed under the drive of the rotating motor 9, so that the windward angle of the arc blades 2 can be adjusted, thereby realizing the adaptive rotation of the arc blades 2 to the wind speed. When the wind speed is high, it can be closed to reduce the rotation speed. When the wind speed is low and there is no rain, the windward surface can be increased to accelerate the rotation and air circulation efficiency.

[0039] Furthermore, the filtering mechanism includes a filter plate 12, which is fixedly mounted on the rotating rod 5, the filter plate 12 is perpendicular to the arc-shaped blades 2, and the width of the filter plate 12 is greater than the spacing between the rotating rods 5. The structure filters the wind entering the device through the filter plate 12, such as Figure 4 It can be seen that after the arc blades 2 are unfolded, the filter plates 12 fit together to form an encirclement, thereby filtering the air entering the arc blades 2 from the outside. When the arc blades 2 are folded, the filter plates 12 will separate from each other and turn to the rotating motor 9. When the arc blades 2 are folded, the equipment is generally required to discharge air. At this time, the wind flows from the inside to the outside, and the wind is not perpendicular to the filter plate 12. Under the action of the wind, the dust on the filter plate 12 will be blown out, thereby achieving self-cleaning.

[0040] Furthermore, the width of the mounting frame 6 is smaller than the width of the double-headed motor 7 and the rotating motor 9, and weight-reducing grooves 13 are provided on the left and right sides of the mounting frame 6. This structure can reduce the weight and area of ​​the mounting frame 6, thereby reducing the wear of the equipment during rotation and increasing the efficiency of air circulation.

[0041] Further, the locking mechanism includes a rotation groove 14, a rotation groove 14 is opened on the lower side of the upper mounting frame 6, a swivel 15 is arranged on the lower side of the rotation groove 14, a limit ring 16 is fixedly installed on the upper end of the swivel 15, the limit ring 16 is rotatably installed in the rotation groove 14, a connecting frame 17 is fixedly installed on the swivel 15, the upper end of the connecting frame 17 is fixedly installed on the output shaft of the rotating motor 9, a first hinged rod 18 is rotatably installed on the rotating rod 5, a second hinged rod 19 is rotatably installed on the first hinged rod 18, and the first hinged rod 19 is rotatably installed on the second hinged rod 19. An insertion block 20 is movably mounted on the second hinged rod 19, a guide block 21 is fixedly mounted at the center position of the lower end of the upper mounting frame 6, a fixed cylinder 22 is fixedly mounted on the output end of the double-headed motor 7, the fixed cylinder 22 is rotatably mounted in the guide block 21, and an insertion groove 23 is provided on the front and rear sides of the fixed cylinder 22, the insertion block 20 is inserted in the insertion groove 23 and the edge of the end is rounded, the insertion block 20 is movably inserted in the guide block 21 and the guide block 21 fits with the insertion block 20, as shown in FIG. Figure 5 and Figure 7 As shown, this structure allows the insertion block 20 to be inserted into the insertion slot 23 when the arc-shaped blade 2 is unfolded under the drive of the rotating motor 9, thereby realizing the connection between the double-headed motor 7 and the mounting disc 1, so that the arc-shaped blade 2 can rotate under the drive of the double-headed motor 7, and can actively control the air intake rate.

[0042] Furthermore, a movable groove 24 is opened on the second hinged rod 19, and a guide rod 25 is movably inserted in the movable groove 24. A spring 26 is sleeved on the guide rod 25. One end of the spring 26 is fixedly mounted on the insertion block 20 and the other end is fixedly mounted on the second hinged rod 19. This structure increases the adaptability of the device when the insertion block 20 is fully inserted into the fixed cylinder 22 and allows the arc-shaped blade 2 to continue to unfold.

[0043] Furthermore, a solar panel 27 is fixedly mounted on the upper mounting disc 1, and a protective cover 28 is fixedly mounted on the mounting disc 1. The protective cover 28 is transparent and has rounded edges. This structure allows the device to be powered by the solar panel 27, reducing energy consumption.

[0044] Furthermore, a mounting plate 29 is fixedly mounted on the output shaft at the lower end of the double-headed motor 7, and four groups of dust adsorption blocks 8 are rotatably mounted on the mounting plate 29. The outer side of the dust adsorption block 8 is heavier than the inner side of the dust adsorption block 8. This structure allows the dust adsorption block 8 to gradually become horizontal under the action of centrifugal force when the double-headed motor 7 is started, thereby achieving efficient adsorption of dust in the air entering the device.

[0045] Furthermore, the dust adsorption blocks 8 are fan-blade-shaped, and the four groups of dust adsorption blocks 8 are not parallel. This structure enables the dust adsorption blocks 8 to stir the air so that the air is discharged downward, thereby increasing the ventilation efficiency of the equipment.

[0046] Working principle: when the angle of the arc blade 2 needs to be adjusted, the rotary motor 9 is started, and the output shaft of the rotary motor 9 rotates to drive the gear ring 10, and the gear ring 10 drives the arc blade 2 to expand or contract through the engagement with the tooth groove 11, thereby realizing the angle adjustment of the arc blade 2. When the arc blade 2 is expanded, the output shaft of the rotary motor 9 rotates to drive the connecting frame 17 and the rotating ring 15 to rotate. At this time, the limit ring 16 rotates in the rotating groove 14, so that the first hinge rod 18 gradually becomes parallel to the second hinge rod 19, and the second hinge rod 19 is squeezed by the first hinge rod 18 so that the insertion block 20 squeezes the fixed cylinder 22. If the fixed cylinder 22 is not exactly engaged in the fixed cylinder 22, the insertion block 20 will move closer to the position of the second hinge rod 19. At this time, the guide rod 2 5 moves in the movable groove 24 and compresses the spring 26, and then starts the double-headed motor 7. The output shaft of the double-headed motor 7 drives the fixed cylinder 22 to rotate, so that the insertion block 20 can be engaged in the insertion groove 23, thereby realizing the connection between the mounting disc 1 and the output shaft of the double-headed motor 7. At this time, the double-headed motor 7 can drive the arc blade 2 to rotate. Since the double-headed motor 7 is only fixed to the mounting disc 1 when the arc blade 2 is unfolded, the double-headed motor 7 is generally started when air is required to enter. When the double-headed motor 7 is started, the dust adsorption block 8 will be driven to rotate and gradually become horizontal, thereby guiding the air and adsorbing the dust in the air. When the air is discharged, it will be vertical under the action of gravity and will not affect the normal air discharge. The above is the entire working principle of the present invention.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
