Therefore, it is necessary to use wind deflectors to adjust the air volume at any time. Currently, the structure and principle of wind deflectors are relatively complex. The wind deflector of this invention adjusts the air volume passing through the air purification device by converting gravitational potential energy and wind kinetic energy. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the present invention provides a non-powered windbreak assembly, an electric field device, and a method for installing the windbreak assembly.

[0004] To achieve the above and other related objectives, the present invention provides the following examples:

[0005] In one aspect, the present invention provides a non-powered windbreak assembly disposed within an airflow channel inside a housing, for controlling the flow of outdoor air into the airflow channel, the airflow channel including an outdoor end and an indoor end higher than the outdoor end, and the airflow channel being configured at least to allow outdoor natural wind to enter the room.

[0006] The windbreak assembly is characterized in that it comprises:

[0007] A fixed baffle is disposed within the airflow channel and fixedly connected to the housing.

[0008] A movable baffle is disposed within the airflow channel and upstream of the fixed baffle, so that the outdoor wind passes through the movable baffle before passing through the fixed baffle. The top of the movable baffle is movably connected to the housing and is adjacent to the top of the fixed baffle.

[0009] In windless conditions, the movable baffle hangs down naturally under gravity, and the lower part of the movable baffle is separated from the lower part of the fixed baffle. The movable baffle and the fixed baffle form an angle gap of x, allowing air to enter the airflow channel through the angle gap. In windy conditions, the movable baffle and the fixed baffle are parallel or form the angle gap of y, where 0 < y < x.

[0010] Preferably, the fixed baffle is not perpendicular to the ground.

[0011] Preferably, under windless conditions, the movable baffle hangs down naturally and is perpendicular to the ground.

[0012] Preferably, when the movable baffle is perpendicular to the ground, the angle of the gap formed between it and the fixed baffle is m, and under windless conditions, the angle of the gap formed between the movable baffle and the fixed baffle is x, where m > x.

[0013] Preferably, when the movable baffle is perpendicular to the ground, the angle of the gap formed between it and the fixed baffle is m. Under windless conditions, the angle of the gap formed between the movable baffle and the fixed baffle is x, where m < x.

[0014] Preferably, under windy conditions, when the wind is light, the movable baffle and the fixed baffle form an angle gap of angle y; when the wind is strong, the movable baffle and the fixed baffle are parallel.

[0015] Preferably, the movable baffle includes a first large hole area and a first small hole area, and the fixed baffle includes a second large hole area and a second small hole area, wherein the ventilation area of ​​the first large hole area is larger than the ventilation area of ​​the second small hole area, and the ventilation area of ​​the second large hole area is larger than the ventilation area of ​​the first small hole area.

[0021] Preferably, when the position of the through hole on the connecting piece is different, causing the movable baffle to be movably connected to the housing, the center of gravity of the movable baffle when it hangs naturally under the action of gravity is different, which in turn causes the angle x of the gap between the movable baffle and the fixed baffle to be different.

[0022] In one aspect, the present invention provides an electric field device, characterized in that the electric field device includes an electric field component and a windbreak component, the windbreak component being any of the windbreak components described above, the electric field component being disposed in an airflow channel within the housing, and the electric field device being configured such that an outdoor object passes sequentially through a movable baffle, a fixed baffle, and the electric field component before entering an indoor space.

[0024] The housing is installed at an angle within the wall. An airflow channel is provided inside the housing, comprising an outdoor end and an indoor end higher than the outdoor end. This ensures that the fixed baffle in the windproof assembly is not perpendicular to the bottom surface. Under windless conditions, the movable baffle in the windproof assembly hangs down naturally due to gravity, and the lower part of the movable baffle separates from the lower part of the fixed baffle.

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0035] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0036] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0037] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0038] One embodiment of the present invention provides a non-powered windshield assembly, referring to... Figures 1-4A non-powered windbreak assembly 10 is disposed within an airflow channel 21 inside the housing 20 and is used to control the flow of outdoor air into the airflow channel 21. The airflow channel 21 includes an outdoor end 211 and an indoor end 212 that is higher than the outdoor end 211. The airflow channel 21 is configured to allow outdoor natural wind to enter the room. The windbreak assembly 10 includes: a fixed baffle 11 disposed within the airflow channel 21 and fixedly connected to the housing 20; and a movable baffle 12 disposed within the airflow channel 21 and located upstream of the fixed baffle 11, so as to allow indoor air to enter the room. The external wind first passes through the movable baffle 12 and then through the fixed baffle 11. The top of the movable baffle 12 is movably connected to the housing 20 and is close to the top of the fixed baffle 11. Under windless conditions, the movable baffle 12 hangs down naturally by gravity and the lower part of the movable baffle 12 is separated from the lower part of the fixed baffle 11. The movable baffle 12 and the fixed baffle 11 form an angle gap of x so that the wind enters the airflow channel 21 through the angle gap. Under windy conditions, the movable baffle 12 and the fixed baffle 11 are parallel or form an angle gap of y, where 0 < y < x.

[0039] With this design, the movable baffle 12 swings by the mutual conversion of gravitational potential energy and wind kinetic energy, thereby achieving automatic control of the wind speed on one side of the shell 20.

[0040] It should be noted that:

[0041] 1. The "no wind" in this invention includes two situations: the first situation is when there is no wind outdoors, and the second situation is when the kinetic energy of the outdoor wind is insufficient to make the movable baffle rotate.

[0042] 2. The movable baffle hangs down naturally due to gravity, which includes two situations: the first situation is that the movable baffle is perpendicular to the bottom surface, and the second situation is that the movable baffle is not perpendicular to the bottom surface.

[0043] 3. Due to the inclined angle between the casing and the ground, the airflow channel is set at an angle. This means the fixed baffle is not perpendicular to the bottom surface, resulting in a gap between the fixed and movable baffles. Air enters the casing through this gap, and the difference between the inlet velocity and the velocity passing through the casing is minimal. As the wind speed increases, the gap between the fixed and movable baffles narrows, reducing the airflow velocity in the airflow channel. When the wind speed reaches a certain level, the movable baffle, under the kinetic energy of the wind, rotates to be parallel to (close to or almost overlapping with) the fixed baffle. The angle between the fixed and movable baffles becomes zero, and air can only pass through the openings on the movable and fixed baffles. The airflow velocity in the airflow channel is even lower, thus reducing the airflow velocity in the airflow channel and making it unaffected by the outdoor wind speed. Without this wind-blocking component, excessively high natural wind speeds would reduce the air purification effect of the electric field.

[0044] 4. Further illustrate the concepts of angular gaps with angles of x or y, and parallelism, using diagrams:

[0045] (1)Reference Figure 5 Under windless conditions, the movable baffle 12 hangs down naturally by gravity and the lower part of the movable baffle 12 separates from the lower part of the fixed baffle 11, forming an angle gap of x between the movable baffle 12 and the fixed baffle 11.

[0046] (2)Reference Figure 6 Under windy conditions, the movable baffle 12 and the fixed baffle 11 form an angle gap of y, where 0 < y < x.

[0047] (3)Reference Figure 7 In windy conditions, the movable baffle 12 is parallel to the fixed baffle 11.

[0048] In one embodiment of the present invention, reference is made to Figures 1-4 The fixed baffle 11 is not perpendicular to the ground.

[0049] In one embodiment of the present invention, referring to Figures 1-4 In windless conditions, the movable baffle 12 hangs down naturally and is perpendicular to the ground.

[0050] In one embodiment of the present invention, when the movable baffle is perpendicular to the ground, the angle of the gap formed between it and the fixed baffle is m. Under windless conditions, the angle of the gap formed between the movable baffle and the fixed baffle is x, where m > x. That is to say, under windless conditions, the movable baffle tilts towards the fixed baffle due to gravity.

[0051] In one embodiment of the present invention, when the movable baffle is perpendicular to the ground, the angle of the gap formed between it and the fixed baffle is m. Under windless conditions, the angle of the gap formed between the movable baffle and the fixed baffle is x, where m < x. That is to say, under windless conditions, the movable baffle tilts towards the outside due to gravity.

[0052] In one embodiment of the present invention, reference is made to Figure 1 and Figure 3 Under windy conditions, when the wind is light, the movable baffle 12 and the fixed baffle 11 form an angle gap 13 with an angle of y. In other words, the wind at this time causes the angle gap 13 between the fixed baffle 11 and the movable baffle 12 to decrease. (Refer to...) Figure 4 When the wind is strong, the movable baffle 11 is parallel to the fixed baffle 12. That is, under the action of the kinetic energy of the wind, the movable baffle 11 rotates to be close to or almost overlap with the fixed baffle 12.

[0053] It should be noted that the specific wind speed values ​​for strong and light winds are related to the material and weight of the movable baffle. Generally speaking, a light wind is enough to move the movable baffle and change the angle gap between the movable and fixed baffles from x to y. A strong wind is enough to move the movable baffle and change the angle gap between the movable and fixed baffles from x to parallel. For example, a wind speed greater than or equal to F m / s is considered a strong wind, and a wind speed less than F m / s is considered a light wind. The movable baffle can be made of stainless steel or plastic. Those skilled in the art will understand that, in case one, when the movable baffle is made of stainless steel, the value of F is greater than when the movable baffle is made of plastic; in case two, when both movable baffles are made of stainless steel, the greater the weight of the movable baffle, the greater the value of F.

[0054] In one embodiment of the present invention, reference is made to Figure 1 The movable baffle 12 includes a first large hole area 121 and a first small hole area 122, and the fixed baffle 11 includes a second large hole area 111 and a second small hole area 112. The ventilation area of ​​the first large hole area 121 is larger than that of the second small hole area 112, and the ventilation area of ​​the second large hole area 111 is larger than that of the first small hole area 122.

[0055] In one embodiment of the present invention, reference is made to Figure 1 and Figure 3 When the movable baffle 12 and the fixed baffle 11 form an angled gap, the outdoor wind enters the room through the angled gap 13, the first large hole area 121 and the first small hole area 122, and then through the second large hole area 111 and the second small hole area 112.

[0056] With this design, when the angled gap 13 changes from x to y, that is, the angled gap 13 decreases, the airflow speed in the airflow channel decreases, thereby achieving the purpose of reducing the airflow speed in the airflow channel.

[0057] In one embodiment of the present invention, reference is made to Figure 4 When the movable baffle 12 is parallel to the fixed baffle 11, the first large hole area 121 is covered by the second small hole area 112, and the second large hole area 111 is covered by the first small hole area 122. The actual ventilation area when the outdoor wind enters the room is the first small hole area 122 and the second small hole area 112.

[0058] With this design, when the movable baffle rotates to be parallel to (close to or almost overlapping with) the fixed baffle, the angle between the fixed baffle and the movable baffle is 0. The wind can only pass through the openings on the movable baffle and the fixed baffle. The wind speed in the airflow channel will be lower, thereby achieving the purpose of reducing the wind speed in the airflow channel.

[0059] In one embodiment of the present invention, reference is made to Figure 1 and Figure 2 The wind deflector assembly 10 also includes a rotating shaft 14 fixedly connected to the housing 20, and the movable baffle 12 also includes a through hole 123. The movable baffle 12 is movably connected to the housing 20 by means of the through hole 123 being sleeved on the rotating shaft 14.

[0060] In one embodiment of the present invention, reference is made to Figure 1 The movable baffle 12 also includes a connecting unit 124. The connecting unit 124 includes connecting arms 125 extending outward along the plane of the movable baffle 12 on opposite sidewalls at the top of the movable baffle 12, and connecting pieces 126 perpendicular to the connecting arms 125. Through holes 123 are provided in the connecting pieces 126.

[0061] In one embodiment of the present invention, reference is made to Figure 1 Under windless conditions, the value of the angle x of the gap formed by the movable baffle 12 and the fixed baffle 11 depends on the position of the through hole 123.

[0062] It should be noted that, referring to Figure 1 When the position of the through hole 123 on the connecting piece 126 is different, the center of gravity of the movable baffle 12 when it is naturally drooping under the action of gravity is different when the movable baffle 12 is movably connected to the housing 20. Therefore, the angle x of the gap between the movable baffle 12 and the fixed baffle 11 is different.

[0063] An embodiment of the present invention provides an electric field device, which includes an electric field component and a windbreak component. The windbreak component is the windbreak component described in any of the above embodiments. The electric field component is disposed in an airflow channel within a housing. The electric field device is configured such that an outdoor device passes through a movable baffle, a fixed baffle, and the electric field component in sequence before entering an indoor device.

[0064] This design ensures that the wind speed in the airflow channel is unaffected by the outdoor natural wind speed, thus improving the air purification effect of the electric field. Without this windbreak component, if the natural wind speed is too high, the wind speed flowing through the airflow channel will also be too high, which would reduce the purification effect of the electric field.

[0065] An embodiment of the present invention provides a method for installing a windshield assembly, characterized by comprising the following steps:

[0066] The housing is installed at an angle within the wall. An airflow channel is provided inside the housing, comprising an outdoor end and an indoor end higher than the outdoor end. This ensures that the fixed baffle in the windbreak assembly is not perpendicular to the bottom surface. Under windless conditions, the movable baffle in the windbreak assembly hangs down naturally due to gravity, and the lower part of the movable baffle separates from the lower part of the fixed baffle. The movable baffle and the fixed baffle form an angled gap of angle x, allowing air to enter the airflow channel through the angled gap. Under windy conditions, the movable baffle and the fixed baffle are parallel or form the angled gap of angle y, where 0 < y < x. The windbreak assembly is any of the windbreak assemblies described in the above embodiments.

[0067] According to the above embodiments, this patent produces the following beneficial effects:

[0068] The windbreak component of this invention adjusts the ventilation volume of the air purification device by converting gravitational potential energy and wind kinetic energy. It has a simple structure, is energy-saving and environmentally friendly, and improves the air purification effect of the electric field.

[0069] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to the present invention. These equivalent forms also fall within the scope defined by the appended claims.
