Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-generating fresh air fans, in particular to an oxygen-generating fresh air fan with adjustable air volume. Background Art

[0002] The fresh air fan is an effective air purification equipment that can circulate indoor air. On the one hand, it discharges the polluted indoor air to the outside, and on the other hand, it inputs the fresh outdoor air into the room after sterilization, disinfection, filtration and other measures, so that the room is filled with fresh and clean air at all times. With the development of science and technology, the existing fresh air fan has developed into a fresh air system with multiple functions, such as oxygen-generating fresh air fan. The oxygen-generating fresh air fan uses the fresh air space oxygen enrichment system to purify the indoor air while also generating oxygen for the room. The fresh air space oxygen enrichment system is an outdoor diffused molecular sieve oxygen generator that produces pure oxygen, which is transported into the indoor main unit through a pipe (the indoor main unit is a fresh air fan). It is used to purify indoor air and improve the oxygen content of indoor air, thereby improving the comfort of people in the area.

[0003] The air volume of the existing oxygen-generating fresh air fan is difficult to be adjusted individually. When in use, the overall air volume of the air outlet can only be reduced, which makes it inconvenient to use. According to a Chinese patent with a patent number of CN211600998U, a fresh air device that can adjust the fresh air volume and the purified air volume individually is pointed out. In this patent, a sliding adjustment frame is used to slide the main isolation plate inside the fresh air connection end through a limiting slide groove, thereby changing the size of the through hole area inside the fresh air connection end, thereby achieving the purpose of changing the exhaust volume of the fresh air connection end and realizing the air volume adjustment of the fresh air fan;

[0004] However, in actual use, the above-mentioned cited patent still has certain usage defects, that is, the main isolation plate and the auxiliary isolation plate used to adjust the air outlet in the document are integrally connected with the adjustment frame, resulting in that when the air outlet is closed and adjusted, the air volume of the two air outlets can only be adjusted at the same time, and the use is relatively simple. Moreover, due to the long-term use of the fresh air outlet, a large amount of dust often accumulates on the filter at the air outlet, and the adjustment device in the cited document lacks the function of scraping dust when adjusting the air volume of the air outlet. The dust will scatter in the slide groove of the adjustment frame, resulting in poor adjustment, and further blocking the filter holes of the fresh air fan, affecting the normal use of the air outlet. Therefore, an oxygen-generating fresh air fan with adjustable air volume is proposed to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-2 In this embodiment, an oxygen-generating fresh air fan with adjustable air volume includes an oxygen-generating fresh air fan body 1, an air outlet is formed on the oxygen-generating fresh air fan body 1, and an air volume adjustment component 3 is arranged at the air outlet.

[0026] In this embodiment, in some cases, excessive air volume may cause discomfort, such as strong wind, dryness, etc.; by closing and adjusting the air volume of the air outlet, the direct wind flow impact can be reduced, the comfort of the indoor air can be improved, and people can feel more comfortable and at ease. By adjusting the air volume of the air outlet fan 2 in different shielding ranges, a more reasonable air distribution can be achieved. By adjusting the air volume of the air outlet, the air flow in different areas can be optimized to ensure that the air is evenly distributed to meet the needs of specific areas.

[0027] See also Figure 3-5 In order to adjust the air volume of the outlet fan 2, the air volume adjustment component 3 in this embodiment includes a mounting frame 31 arranged on the oxygen-generating fresh air machine body 1. The mounting frame 31 is a rectangular frame. The inner walls of the upper and lower sides of the mounting frame 31 are provided with limiting grooves 320. In use, the user uses positioning bolts 32 to install the mounting frame 31 at the air outlet of the air outlet fan 2. Two closing plates 34 are slidably provided in the limiting grooves 320. Positioning holes 310 are provided at the four corners of the mounting frame 31. The positioning holes 310 are engraved with threaded lines and are threadedly connected with positioning bolts 32. The other end of the positioning bolts 32 is threadedly connected to the oxygen-generating fresh air machine body 1.

[0028] In this embodiment, by sliding the closing plate 34 in the mounting frame 31, when the actual user needs to adjust the air volume, the user only needs to slide the closing plate 34 to cover the opening of the air outlet fan 2. By changing the shielding area, precise adjustment of different air volumes can be achieved. By sliding and shielding the air outlet of the air outlet fan 2, the slidable closing plate 34 can adjust the opening size of the air outlet as needed, thereby accurately controlling the size of the air volume. This allows flexible adjustment according to air volume requirements in different situations to meet specific air flow requirements. Compared with the single adjustment in the cited document, its overall practicality is stronger.

[0029] It should be noted that the slidable closing plate 34 can be adjusted according to actual needs to make the system more flexible and adaptable. According to different seasons, environments or usage requirements, the air volume can be adjusted at any time to achieve the best air flow effect.

[0030] See also Figure 3-5 In order to individually adjust the air volume of the air outlet fan 2 and improve the practicality of air volume adjustment, threaded holes are provided on the two closing plates 34 in this embodiment and are threadedly connected with adjusting screws 35;

[0031] An isolation plate 33 is disposed in the limiting groove 320, and the isolation plate 33 is disposed between two closing plates 34; through holes are provided on both lateral side walls of the mounting frame 31, and ball bearings 36 are filled and fitted in the through holes;

[0032] One end of the two adjusting screws 35 extends to the lateral side of the mounting frame 31 and passes through the adjacent ball bearings 36 to extend to the outside. One end of the two adjusting screws 35 is connected to an adjusting head 37.

[0033] Side plates 341 are protruded from both the upper and lower sides of the closing plate 34 , and the side plates 341 are slidably engaged with the limiting grooves 320 .

[0034] In the present embodiment, in actual use, the user can rotate one of the adjusting heads 37. When the adjusting head 37 rotates, the adjusting screw 35 connected thereto can rotate synchronously, and the closing plate 34 meshing with the adjusting screw 35 can slide in the limiting groove 320 until the air outlet of the air outlet fan 2 is closed and adjusted. At the same time, the user can control the number of rotations of the adjusting screw 35 to allow the closing plate 34 to adjust the air outlet fan 2 to different closed areas.

[0035] It should be noted that when the user rotates the two adjustment heads 37 respectively, the two closing plates 34 can also adjust the shielding of the air outlets of the fan 2 at different air outlets respectively. At the same time, through the rotational cooperation between the ball bearing 36 and the adjustment screw 35 arranged on the mounting frame 31, the adjustment head 37 can also be made to rotate more smoothly.

[0036] See also Figure 5The cleaning pad 38 can also protect the air outlet fan 2 and prevent foreign matter from entering the air outlet fan 2.

[0037] The working principle of the above embodiment is:

[0038] In the first step, during use, the user uses the positioning bolt 32 to install the mounting bracket 31 at the air outlet of the air outlet fan 2, and then rotates one of the adjusting heads 37. When the adjusting head 37 rotates, the adjusting screw 35 connected thereto can rotate synchronously, and at the same time, the closing plate 34 meshed with the adjusting screw 35 can slide in the limiting groove 320 until the air outlet of the air outlet fan 2 is closed and adjusted. At the same time, the user can control the number of rotations of the adjusting screw 35 to make the closing plate 34 adjust the air outlet fan 2 to different closed areas; at the same time, by rotating the two adjusting heads 37, the two closing plates 34 can also be respectively adjusted to shield different air outlets of the air outlet fan 2;

[0039] Step 2: When the closing plate 34 is moving, the cleaning pad 38 arranged on the side of the closing plate 34 can clean the dust on the air outlet of the air outlet fan 2 to avoid the accumulation of dust in the air outlet fan 2 when it is in use. At the same time, when the air outlet fan 2 is not in use, the user can adjust the closing plate 34 to the side of the air outlet fan 2 and completely cover the air outlet fan 2. At this time, the cleaning pad 38 arranged can also protect the air outlet fan 2 to prevent external impurities from entering the air outlet fan 2.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
