Description

Technical Field

[0001] This invention relates to the field of ventilation window technology, and in particular to a protective ventilation window with electric function. Background Technology

[0002] Ventilation windows are typically used for ventilation of outdoor cabinets, new energy equipment, and other equipment with high waterproofing requirements. They generally feature blades of a specific shape that block and guide the airflow along a predetermined path, preventing water, sand, and other contaminants from entering, thus meeting ventilation and high protection requirements. However, current ventilation windows lack closing and opening functions. Regardless of the outdoor environment, the ventilation window remains in a ventilated state. For example, when the outside temperature is too low, the ventilation window's operation can cause the indoor temperature to drop, affecting the normal operation of the equipment. Therefore, it is necessary to both close and open the ventilation window. The common practice is manual blocking, such as placing baffles outside the ventilation window. This requires manual intervention and is not very practical. Furthermore, in some harsh environments or during severe weather events, such as on islands or in blizzards, it is difficult to manually block the ventilation window. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a protective ventilation window with electric function, which can realize the electric opening and closing of the protective ventilation window.

[0032] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0033] The following is for reference. Figures 1 to 8 A protective ventilation window with an electric function is described according to an embodiment of the present invention, wherein air is set to pass through the protective ventilation window from front to back.

[0034] like Figures 1 to 4 As shown, the protective ventilation window with electric function according to an embodiment of the present invention includes a frame assembly, a louver mechanism, a protective blade assembly 300, and a filter assembly 400. An air inlet channel is formed inside the frame assembly. The louver mechanism includes a louver blade assembly 210 and an electric drive mechanism 220. The louver blade assembly 210 includes a plurality of louver blades 211 rotatably disposed on the frame assembly and distributed in the vertical direction. The electric drive mechanism 220 can drive the louver blades 211 to rotate to open or close the air inlet channel. The protective blade assembly 300 is located behind the louver blades 211. The protective blade assembly 300 includes a plurality of protective blades 310 spaced apart in the vertical direction on the frame assembly. A diversion channel 301 for air to pass through is formed between adjacent protective blades 310. The filter assembly 400 is disposed on the frame assembly and located behind the protective blade assembly 300.

[0035] The ventilation window can be opened or closed by driving the louver blades 211 to rotate via the electric drive mechanism 220, thus meeting the ventilation requirements of dustproof and waterproof ventilation as well as the requirements of closure and isolation.

[0036] Specifically, when the louver blades 211 are open, outside air can pass through the louver blades 211 and the diversion channel 301 from front to back, and finally enter the room after being filtered by the filter assembly 400, thereby achieving the effect of ventilation and providing a high level of protection. When the louver blades 211 are closed, the louver blades 211 block outside air from entering the diversion channel 301, thereby achieving the effect of closing the ventilation window.

[0037] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the frame assembly includes an outer frame 110 and an inner frame 120 disposed within the outer frame 110, and a louver blade assembly 210 and a protective blade assembly 300 are disposed in the inner frame 120 to facilitate the assembly and maintenance of the ventilation window.

[0038] Specifically, during the production and assembly of the ventilation window, the outer frame 110 and the inner frame 120 can be produced independently. The louver blade assembly 210 and the protective blade assembly 300 are installed on the inner frame 120 before assembling the outer frame 110 and the inner frame 120, making assembly more convenient. The inner frame 120, louver blade assembly 210, and protective blade assembly 300 form a modular unit, facilitating the replacement of the louver blade assembly 210 and the protective blade assembly 300 to meet different usage requirements and simplifying maintenance.

[0039] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, a cavity is formed between the outer frame 110 and the inner frame 120 to accommodate the electric drive mechanism 220, so as to better protect the electric drive mechanism 220.

[0040] Specifically, the inner frame 120 has a recessed cavity 121 on its side. The upper and lower frame strips of the inner frame 120 respectively block the openings at the upper and lower ends of the recessed cavity 121. The outer frame 110 blocks the lateral openings of the recessed cavity 121, thereby forming a closed cavity. The electric drive mechanism 220 is located in this cavity. Dust, rainwater, etc. are not easy to fall into the cavity, thus protecting the electric drive mechanism 220 well.

[0041] In some embodiments of the present invention, the inner frame 120 is a square structure composed of four frame strips, namely an upper frame strip 122, a lower frame strip 123, a left frame strip 124, and a right frame strip 125. The concave cavity 121 is provided in the left frame strip 124. The upper end and the lower end of the left frame strip 124 are respectively connected to the lower end face of the upper frame strip 122 and the upper end face of the lower frame strip 123, thereby blocking the upper and lower openings of the concave cavity 121.

[0042] Specifically, the upper frame strip 122, the lower frame strip 123, the left frame strip 124, and the right frame strip 125 are profile structures.

[0043] In some embodiments of the present invention, the inner frame 120 is detachably mounted on the outer frame 110 to facilitate the assembly and maintenance of the ventilation window.

[0044] Specifically, the outer frame 110 and the inner frame 120 can be detachably connected by screw mechanisms, snap-fit ​​mechanisms, pin mechanisms, etc.

[0045] like Figure 7 , Figure 8 As shown, in some embodiments of the present invention, the inner side of the outer frame 110 is provided with a first step positioning structure 111 that allows the inner frame 120 to be installed from front to back, so as to facilitate the assembly and disassembly of the inner frame 120.

[0046] Specifically, such as Figure 8 As shown, the first step positioning structure 111 forms an opening facing forward that corresponds to the outer contour of the inner frame 120, so that the inner frame 120 can be inserted. After the inner frame 120 is inserted into the first step positioning structure 111, its rear side is limited by the first step positioning structure 111. At the same time, the outer frame 110 and the inner frame 120 are connected by screws, buckles, etc., thereby fixing the outer frame 110 and the inner frame 120.

[0047] like Figure 7 , Figure 8 As shown, in some embodiments of the present invention, a second step positioning structure 112 is formed between the outer frame 110 and the inner frame 120 to allow the filter assembly 400 to be installed from back to front, so as to facilitate the installation of the filter assembly 400.

[0048] Specifically, such as Figure 7 , Figure 8 As shown, an inner extension plate 126 is provided on the rear side of the inner frame 120. After the outer frame 110 is assembled with the inner frame 120, the inner extension plate 126 and the outer frame 110 form a second step positioning structure 112 with an opening facing forward and corresponding to the outer contour of the filter assembly 400, which facilitates the assembly and disassembly of the filter assembly 400.

[0049] In some embodiments of the present invention, the inner extension plate 126 is located on the rear side of the protective blade assembly 300, which can block the gap between the outer edge of the protective blade assembly 300 and the inner side of the inner frame 120, reduce air leakage, and improve the anti-slip effect.

[0050] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the outer frame 110 is provided with a limiting mechanism that can limit the filter assembly 400 to the second step positioning structure 112, so as to realize the installation and fixation of the filter assembly 400.

[0051] Specifically, after the filter assembly 400 is installed into the second step positioning structure 112, the front side of the filter assembly 400 abuts against the second step positioning structure 112, and the limiting mechanism limits the rear side of the filter assembly 400, thereby fixing the filter assembly 400 to the frame assembly.

[0052] like Figure 3 As shown, in some embodiments of the present invention, the limiting mechanism includes a limiting member 131 disposed on one side of the outer frame 110 and a rotating member 132 rotatably disposed on the other side of the outer frame 110. During assembly, the filter assembly 400 is first inserted obliquely into the front side of the limiting member 131, so that one side of the filter assembly 400 is limited between the limiting member 131 and the second step positioning structure 112. Then, the filter assembly 400 is fully pushed into the second step positioning structure 112 (the rotating member 132 is rotated to the avoidance position). The rotating member 132 is rotated to the rear side of the filter assembly 400, thereby limiting the other side of the filter assembly 400 between the rotating member 132 and the second step positioning structure 112.

[0053] Of course, in the specific implementation process, the limiting mechanism can also be a clamping mechanism, a sliding blocking mechanism, etc., which will not be described in detail here.

[0054] In some embodiments of the present invention, the filter assembly 400 has a plate-like structure, and filter media such as coconut shell, filter cotton, activated carbon, etc. are disposed inside it.

[0055] like Figure 6 As shown, in some embodiments of the present invention, the upper part of the louver blade 211 is provided with a connecting part 212 that is rotatably connected to the frame assembly, and the lower part of the louver blade 211 is provided with an outer covering part 213 corresponding to the outer contour of the connecting part 212. The outer covering part 213 of the upper louver blade 211 can partially cover the connecting part 212 of the lower louver blade 211, so that when the louver blade assembly 210 is closed, it has good airtightness and achieves a good blocking effect, so that the ventilation window has a good protective effect.

[0056] Specifically, such as Figure 6 As shown, the connecting part 212 has a circular cross-section, and the outer part 213 is a curved structure that can cover the front side of the connecting part 212, thereby achieving a better sealing effect.

[0057] It is understood that in some embodiments of the present invention, the connecting part 212 may also be configured to have a square cross-section, and the outer part 213 may be configured to have a corresponding square groove structure, which can also achieve a better sealing effect.

[0058] like Figure 2 , Figure 3As shown, in some embodiments of the present invention, the electric drive mechanism 220 includes a drive unit 221, a connector 222, and a swing arm 223. The swing arm 223 is configured in a one-to-one correspondence with the louver blades 211. The connector 222 is an elongated structure extending in the vertical direction. One end of the swing arm 223 is connected to the connecting part 212, and the other end is hinged to the connector 222. The drive unit 221 can drive the connector 222 to move up and down, and drive the louver blades 211 to swing through the swing arm 223, thereby opening or closing the louver mechanism.

[0059] In some embodiments of the present invention, the drive unit 221 is an electric cylinder mechanism. Of course, in specific implementation, the drive unit 221 may also be a pneumatic cylinder, hydraulic cylinder, etc., which will not be described in detail here.

[0060] It is understood that in some embodiments of the present invention, the electric drive mechanism 220 may also be a gear mechanism driven by a motor, which will not be described in detail here.

[0061] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments of the present invention, an upper blocking member 127 is provided on the upper part of the inner side of the inner frame 120. The upper blocking member 127 can block the gap between the upper part of the louver blade assembly 210 and the upper part of the inner side of the inner frame 120, reduce air leakage, and improve the blocking effect when the louver blade assembly 210 is closed.

[0062] like Figure 5 As shown, in some embodiments of the present invention, the diversion channel 301 includes an air inlet 302, a first lifting channel 303, and a second lifting channel 304 connected sequentially along the airflow direction. The air inlet 302 is an flared structure that gradually expands from back to front. The first lifting channel 303 extends upward and obliquely forward, and the second lifting channel 304 extends upward and obliquely backward. This allows the air entering through the air inlet 302 to undergo a first turn before entering the first lifting channel 303 and climbing upward and obliquely forward, and then undergo a second turn before entering the second lifting channel 304 and climbing upward and obliquely backward. Finally, the air is discharged through the air outlet. This allows dust, rainwater, etc., to be blocked or deposited downward during the two turns and two climbs, thereby improving the protective effect of the protective blade assembly 300.

[0063] It is conceivable that in some embodiments of the present invention, the diversion channel 301 may also be configured in other shapes, such as W-shaped, spaced double V-shaped, etc., which will not be described in detail here.

[0064] like Figure 5As shown, in some embodiments of the present invention, the protective blade 310 includes a first blade 311, a second blade 312, a third blade 313, and a fourth blade 314 connected sequentially from top to bottom. The first blade 311 extends downward and obliquely forward, the second blade 312 extends downward and obliquely backward, the third blade 313 extends downward and obliquely forward, and the fourth blade 314 extends downward and obliquely backward. An air inlet 302 is formed between the fourth blade 314 and the third blade 313 of adjacent protective blades 310. A first lifting channel 303 is formed between the fourth blade 314 and the second blade 312 of adjacent protective blades 310. A second lifting channel 304 is formed between the third blade 313 and the first blade 311 of adjacent protective blades 310, so as to form the above-mentioned diversion channel 301 with two turns and two climbs.

[0065] It is understood that in some embodiments of the present invention, the protective blade 310 may also be configured in other shapes, such as S-shaped blades, V-shaped blades, etc., which will not be described in detail here.

[0066] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
