Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor activity room facilities, and particularly relates to a ventilation component of an outdoor activity room. Background Art

[0002] An outdoor activity room generally refers to an environmentally friendly and economical house with a light steel skeleton, sandwich panels as enclosure materials, spatial combination in a standard modular series, and components connected by bolts. It is often used for outdoor temporary buildings such as temporary office rooms and temporary accommodation rooms during outdoor construction. Since the aforementioned activity room is mainly used to meet temporary use requirements and the single-use cycle is not too long, its structure is not built according to permanent facilities. Naturally, in some characteristics, it lacks the characteristics of permanent facilities, such as ventilation and heat insulation performance. As mentioned above, the current outdoor activity room is built based on steel structures and sandwich panels. Under the condition of direct sunlight outdoors, the internal temperature of the activity room is relatively high and the air flow is difficult to circulate, resulting in a very stuffy environment, which causes great trouble to the people inside the activity room.

[0003] By configuring a ventilation component for the activity room, it will help to solve the aforementioned technical problems. The ventilation component discharges the turbid and stuffy air flow inside to the outside and extracts the relatively fresh air outside into the room. Considering the temporary application attribute of the outdoor activity room, the ventilation component should also have characteristics such as temporary application, quick disassembly, assembly and transfer, etc., to meet the special requirements of disassembly, assembly and transfer for use in multiple scenarios. The existing ventilation components do not have the aforementioned characteristics and are difficult to meet the current needs, so it is necessary to develop and design them specifically.

When the valve plate 3 swings to one side, the upper part of the inner cavity of the main box 8 is communicated with the inner cavity of the side box 4, and an induced draft channel is established inside. When the valve plate 3 swings to the other side, the inner cavities of the main box 8 and the side box 4 are isolated, then the main box 8 is communicated, and an exhaust channel is established inside. Therefore, this ventilation component can drive the valve plate 3 to swing to different positions through the operating component, and switch between the exhaust mode to the outside and the induced draft mode to the inside.

[0023] In this embodiment, the ventilation component is installed on the activity room 13 in the state shown in Figure 1 , specifically at the transition joint between the wall and the top wall of the activity room 13, so as to minimize the occupation of the indoor space of the activity room 13. When correctly installed, the center line of the main box 8 is in the vertical direction, so the established exhaust channel is in the vertical direction, and the included angle between the center line of the side box 4 and the center line of the main box 8 is 45°, so the established induced draft channel first goes vertically downward and then deflects obliquely downward by 45° to the outside.

[0024] In this embodiment, the operating component includes a rotating shaft 16 mounted between the front wall and the rear wall of the main box body 8 by means of a shaft seat 17. The bottom edge of the valve plate 3 is fixedly connected to the rotating shaft 16. A swing arm 15 is installed at the front end of the rotating shaft 16, and a pull rod 10 is installed at the end of the swing arm 15 through a connecting seat 14. As Figure 2 shown in, a strip-shaped hole extending along the length direction is provided on the swing arm 15, and the connecting seat 14 is connected to the swing arm 15 by means of a pin shaft located in the strip-shaped hole. By pulling down or pushing up the pull rod 10, the swing arm 15 can be operated to swing, and then the rotating shaft 16 can be operated to drive the valve plate 3 to perform a deflection action.

[0025] In this embodiment, a protective cover 7 fixed to the front parts of the main box body 8 and the side box body 4 is further included. The protective cover 7 encloses the main part of the operating component inside, and the lower end of the pull rod 10 is exposed from a window at the bottom of the protective cover 7.

The functions of setting the top flange 18, the bottom flange 20 and the side flange 19 are to improve the convenience of connection between the main part of this ventilation component and the movable house 13 and its accessories.

[0027] In this embodiment, a filter screen 9 is provided in the middle of the inner cavity of the side connecting cylinder 5. The filter screen 9 is fixedly connected to the side connecting cylinder 5 by fixing screws penetrating from the outside. The filter screen 9 is used to filter the air flow introduced into the room, avoiding dust, flying fluffs, etc. from entering the room, and the filter screen 9 is disassembled and cleaned or disassembled and replaced regularly.

[0028] A rain-proof ventilation cap 1 is installed above the top connecting cylinder 2, and the main part of the ventilation component is located indoors while the rain-proof ventilation cap 1 is located outdoors. The rain-proof ventilation cap 1 has a certain rain-proof effect while meeting the requirements of air flow discharge and entry, avoiding rain water from entering the interior. As Figure 1 shown in, the rain-proof ventilation cap 1, the installation boss on the top wall of the movable house 13 and the top flange 18 are fixedly connected by bolts, and a sealing gasket can be set at the connection position.

[0029] An exhaust fan 12 is installed below the bottom connecting cylinder 11, and an air inlet fan 6 is installed at the end of the side connecting cylinder 5. As shown in the figure, both the exhaust fan 12 and the air inlet fan 6 are flattened fans, and are fixedly connected to the bottom flange 20 and the side flange 19 by bolts respectively.

[0030] Please refer to Figure 3 , it can be seen that:

[0031] The rainproof ventilation cap 1 includes an annular bottom plate 1-1. In the middle of the bottom plate 1-1, a vertically penetrating air duct 1-2 is installed. On the bottom plate 1-1, a lower cylinder 1-6 is also installed through a plurality of support plates 1-3. Above the lower cylinder 1-6, an upper cylinder 1-7 is provided. The lower cylinder 1-6 is made of a mesh plate, so it has the ability to allow air flow through. The upper cylinder 1-7 is made of steel plate and does not have the ability to allow air flow through. The top edge of the lower cylinder 1-6 is fixedly welded to the bottom edge of the upper cylinder 1-7.

[0032] A plurality of connection holes are provided on the annular bottom plate 1-1. These connection holes correspond to the connection holes on the installation boss at the top of the mobile house 13 and the connection holes on the top flange 18. During installation, the annular bottom plate 1-1, the installation boss and the top flange 18 are stacked, and bolts are arranged in each group of connection holes for fixation.

[0033] In this embodiment, the upper radial dimension of the air duct 1-2 is larger than the lower radial dimension, and a necking is provided between the upper part and the lower part.
