With the continuous improvement of quality of life, people have higher requirements for environmental comfort. Therefore, a variety of air treatment devices for improving the environment continuously emerges, and the forms and functions thereof are becoming more abundant. The air treatment device generally needs to input air into the environment to be treated to achieve the purpose of air treatment.

To make the purpose, technical solutions, and advantages of embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

As shown in <FIG>, the present application provides an air outlet mechanism applied to an air treatment device. The air treatment device is provided with a vertical air duct <NUM>. A first upper end surface of the vertical air duct <NUM> is obliquely arranged. The air outlet mechanism includes a first air outlet plate <NUM> and a second air outlet plate <NUM>. The first air outlet plate <NUM> surrounds a higher side of the first upper end surface and is rotatably connected to the air treatment device. The second air outlet plate <NUM> surrounds other parts of the first upper end surface and is connected to the air treatment device. The first air outlet plate <NUM> includes a straight plate rotatably connected to the air treatment device and an arc-shaped plate connected to the straight plate. An end of the second air outlet plate <NUM> away from the first upper end surface is inclined toward an outer side of the air duct <NUM>. An air outlet is formed between the first air outlet plate <NUM> and the second air outlet plate <NUM>. The air outlet can be adjusted by rotating the first air outlet plate <NUM>.

The first air outlet plate <NUM> and the second air outlet plate <NUM> surround the first upper end surface to form the air outlet, and thus the air outlet extends from the vertical air duct <NUM> and diverts the air flow direction. The rotation of the first air outlet plate <NUM> can adjust the shape, size and the air flow direction of the air outlet, increasing the flexibility and controllability of the air output, which is easy to control and achieve satisfactory air supply volume and air blow-down effect, meets the individual requirements of different users, and eliminates dead corners of the air supply. Opposed to the conventional monotonic air outlets, different shapes of air outlets, such as petal shapes, can be realized by designing the shapes of the first air outlet plate <NUM> and the second air outlet plate <NUM>, which greatly increases the diversity and aesthetics of the air outlets.

In some embodiments of the present application, the first upper end surface is surrounded and defined by a straight edge and an arc-shaped edge. The straight edge is perpendicular to the inclination direction of the upper end surface and is located at the highest position of the upper end surface. The height of the arc-shaped edge gradually decreases in a direction away from the straight edge. The straight plate is rotatably connected to the air treatment device through a rotating shaft <NUM> parallel to the straight edge. The second air outlet plate <NUM> is fixedly connected to the arc-shaped edge.

The straight edge of the first upper end surface facilitates the mounting of the rotating shaft <NUM> connected to the first air outlet plate <NUM> and facilitates the rotation of the first air outlet plate <NUM>. The rotating shaft <NUM> is parallel to the straight edge, which increases the airtightness of the connection between the air duct <NUM> and the air outlet to prevent air leakage. The arc-shaped edge cooperates with the straight edge to surround the air duct <NUM>.

In some embodiments of the present application, an angle α between the straight plate and a vertical direction is in a range from <NUM>° to <NUM>°.

As shown in <FIG> and <FIG>, when the angle between the straight plate and the vertical direction is increased from α to α', a distance between a projection point of the free end of the arc-shaped plate on a horizontal plane and the lowest point of the first upper end surface is changed from b to b', and a height difference between the free end of arc-shaped plate and the free end of the second air outlet plate is changed from c to c'. Therefore, when the angle α between the straight plate and the vertical direction is increased, the projection point of the free end of the arc-shaped plate on the horizontal plane moves away from the air duct <NUM>, that is, the distance that the arc-shaped plate extends out from the air duct <NUM> is increased, and the height difference c between the free end of the arc-shaped plate and the free end of the second air outlet plate is decreased, that is, the height of the air outlet becomes smaller. At this time, the first air outlet plate <NUM> is tilted forward, and an air flow guide length of the air outlet is increased, so that the air flow is forcibly redirected. The air will flow in an oblique downward direction, which achieves the effect of air blowing forward and downward from the air outlet, obtaining a relatively good air blow-down effect. However, if the first air outlet plate <NUM> is overly tilted forward, the area of the air outlet will be decreased, which increases resistance to the air flow and decreases the volume of the output air. Tests show that when the angle α between the straight plate and the vertical direction is in the range from <NUM>° to <NUM>°, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time. The two aspects can be both optimized.

In some embodiments of the present application, a tilt angle β of the first upper end surface relative to the horizontal plane is in a range from <NUM>° to <NUM>°.

As shown in <FIG> and <FIG>, when the tilt angle of the first upper end surface relative to the horizontal plane is increased from β to β", the angle between the straight plate and the vertical direction is increased from α to α", the distance between the projection point of the free end of the arc-shaped plate on the horizontal plane and the lowest point of the first upper end surface is changed from b to b", and the height difference between the free end of arc-shaped plate and the free end of the second air outlet plate is changed from c to c". Therefore, when the tilt angle β of the first upper end surface relative to the horizontal plane is increased, the angle α between the straight plate and the vertical direction increases, the projection point of the free end of the arc-shaped plate on the horizontal plane moves away from the air duct <NUM>, that is, the distance that the arc-shaped plate extends out from the air duct <NUM> is increased, and the height difference c between the free end of the arc-shaped plate and the free end of the second air outlet plate is decreased, that is, the height of the air outlet becomes smaller. At this time, the first air outlet plate <NUM> is tilted forward, and an air flow guide length of the air outlet is increased, so that the air flow is forcibly redirected. The air will flow in an oblique downward direction, which achieves the effect of air blowing forward and downward from the air outlet, obtaining relatively good air blow-down effect. However, if the first air outlet plate <NUM> is overly tilted forward, the area of the air outlet will be decreased, which increases resistance to the air flow and decreases the volume of the output air. Tests show that when the tilt angle β of the first upper end surface relative to the horizontal plane is in the range from <NUM>° to <NUM>°, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time. The two aspects can be both optimized.

In some embodiments of the present application, a height difference a between the highest point and the lowest point of the first upper end surface is in a range from <NUM> to <NUM>.

When the height difference a between the highest point and the lowest point of the first upper end surface is in the above-described range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time. The two aspects can be both optimized.

In some embodiments of the present application, the projection of the free end of the arc-shaped plate on the horizontal plane is located in a first range. The first range is from a point at an inner side of and distanced from the lowest point of the first upper end surface by <NUM> to another point at an outer side of and distanced from the lowest point of the first upper end surface by <NUM>.

The projection point of the free end of the arc-shaped plate on horizontal plane can be located at the inner side of the lowest point of the first upper end surface or located at the outer side of the lowest point of the first upper end surface, that is, the distance that the arc-shaped plate extends out from the air duct <NUM> can be a positive value or a negative value. When the distance that the arc-shaped plate extends out from the air duct <NUM> is a positive value, e.g., b' and b", the projection point of the free end of the arc-shaped plate on the horizontal plane is located at the outer side of the lowest point of the first upper end surface. When the distance that the arc-shaped plate extends out from the air duct <NUM> is a negative value, e.g., b , the projection point of the free end of the arc-shaped plate on the horizontal plane is located at the inner side of the lowest point of the first upper end surface. When the projection point of the free end of the arc-shaped plate on the horizontal plane is located in the first range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time. The two aspects can be both optimized.

In some embodiments of the present application, the height difference c between the free end of the arc-shaped plate and the free end of the second air outlet plate is in a range from <NUM> to <NUM>.

The height difference c between the free end of the arc-shaped plate and the free end of the second air outlet plate is the height of the air outlet. When height difference is within the above-described range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time. The two aspects can be both optimized.

In some embodiments of the present application, a horizontal distance d between the highest point of the first upper end surface and the lowest point of the first upper end surface is in a range from <NUM> to <NUM>.

The horizontal distance d between the highest point of the first upper end surface and the lowest point of the first upper end surface is the width of the air duct. When it is in the above-described range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time.

In some embodiments of the present application, a horizontal distance e between the free end of the second air outlet plate, which is substantially in the same vertical plane with the lowest point of the first upper end surface, and the lowest point of the first upper end surface is in a range from <NUM> to <NUM>.

The horizontal distance e between the free end of the second air outlet plate, which is substantially in the same vertical plane with the lowest point of the first upper end surface, and the lowest point of the first upper end surface is the distance that the second air outlet plate is deviated from the first upper end surface. When it is in the above-described range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time.

In some embodiments of the present application, a vertical distance f between the free end of the second air outlet plate, which is substantially in the same vertical plane with the lowest point of the first upper end surface, and the lowest point of the first upper end surface is in a range from <NUM> to <NUM>.

The vertical distance f between the free end of the second air outlet plate, which is substantially in the same vertical plane with the lowest point of the first upper end surface, and the lowest point of the first upper end surface is the height of the second air outlet plate above the first upper end surface. When it is in the above-described range, a balance between air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be both obtained at the same time.

In some embodiments of the present application, a height g of an air flow guide section of the air duct <NUM> is in a range from <NUM> to <NUM>. The height g of the air flow guide section of the air duct <NUM> is the distance from the lowest point of the first upper end surface to the bottom of the air duct <NUM>. When the distance is in the above-described range, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be obtained both at the same time.

In some embodiments of the present application, a second upper end surface <NUM> of the air treatment device is arranged obliquely. The first upper end surface is arranged at a lower side of the second upper end surface <NUM>. The second upper end surface <NUM> is an upper end surface of an air treatment device body <NUM>. The second air outlet plate <NUM> is arranged around the edge of the second upper end surface <NUM>. A decorative component <NUM> is provided between the surface of the first air outlet plate <NUM> away from the air duct <NUM> and the second air outlet plate <NUM> in the second upper end surface <NUM>. Both ends of the first air outlet plate <NUM> are provided with decorative ears facing the decorative component <NUM>, and round chamfers are provided between the decorative ears and the first air outlet plate <NUM>.

The above arrangement increases aesthetics of the second upper end surface <NUM> of the air treatment equipment. The second air outlet plate <NUM> surrounds the second upper end surface <NUM> as a whole, having the decorative component <NUM> located therein, which, as well as the round chamfer design of the first air outlet plate <NUM>, makes the entire second upper end surface <NUM> present a artistic flower-like appearance and is also easy to produce and assemble. The air outlet is integrated with the air treatment device, rendering a complete appearance, which can be conveniently produced and assembled with good performance.

When the above parameters are within the ranges, a balance between the air blow-down effect and the air supply volume can be achieved, that is, better air blow-down effect and larger air supply volume can be obtained at the same time. However, the air blow-down effect and the air supply volume are not optimized. In order to adapt to the individual needs of different users, the air blow-down effect and the air supply volume were tested in the range of each of the above-described parameters. The position parameters achieving the optimized air blow-down effect and the air supply volume were found.

When the air volume is the largest, the air resistance would be the smallest, but the air blow-down effect would be poor. The user may need the air to be quickly supplied to adjust and treat the air in the environment to be treated. Direct supplying air to the user is not required or unfavorable. For example, when an air conditioner refrigerates, rapid cooling and large volume of air supply are required, and it is not suitable to supply air directly to the user. To meet this requirement, the parameters can be adjusted to the following ranges or positions:.

The angle α between the straight plate and the vertical direction is in a range from <NUM>° to <NUM>°;.

When the parameters are respectively in the above ranges or at the points, the air supply volume is the largest.

Opposed to the positions at the maximum air supply volume mentioned above, if the user has no special requirement for the air supply volume but needs the air to be blown down, the air outlet can be adjusted to the air blow-down state. At this time, the first air outlet plate <NUM> is inclined more forward compared to its position when the air supply volume is the largest, and the air flow can be effectively directed to the user's activity area, while the air supply volume which is not too small can also meet the needs of the user. For example, when the air conditioner produces heats, it can be adjusted to this state. To meet this requirement, the parameters can be adjusted to the following ranges or positions:.

When the parameters are respectively in the above ranges or at the points, the air blow-down effect is the best. As shown in <FIG>, when the air treatment device is mounted at a distance of <NUM> from the ground, the air can be blown down to a height of <NUM> at a position in a distance of <NUM> from the mounting wall. The length of a regular room can be up to <NUM>, and <NUM> is enough for the air to be blown to the user.

Based on the same concept, the present application also provides an air treatment device, including the air outlet mechanism. The air treatment device can be an air conditioner or a fresh air ventilator.
