Description

Technical Field

[0001] The present invention relates to the technical field of ventilation systems, and in particular to a roof cap-shaped ventilation system. Background Art

[0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants by means of ventilation dilution or ventilation removal, etc., to achieve the guarantee of indoor and outdoor air environmental quality.

[0003] Currently, in the prior art, most building ventilation systems adopt mechanical ventilation devices to achieve ventilation inside the system. Specifically, most of them are provided with a complete set of devices including air inlets, air outlets, air supply ducts, fans, cooling and heating, filters, control systems, and other auxiliary equipment. Therefore, the existing ventilation systems have the following deficiencies: (1) There are many types of supporting equipment, and the equipment needs to be powered, resulting in high costs and high production costs; (2) The equipment occupies a large amount of space and area, reducing the usable space and area in the building; (3) The ventilation system needs to lay various pipelines, and the construction is relatively cumbersome.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, in view of the deficiencies of the prior art, the main purpose of the present invention is to provide a roof cap-shaped ventilation system with a simple structure, which can realize the self-flow of air inside the roof, automatically achieve the balance of internal and external air pressures in the cap-shaped cavity, and eliminate the settings of devices such as fans, cooling and heating, filters, and control systems in the traditional technology.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] When the internal air temperature of the cap-shaped cavity rises, the internal air expands and rises due to heat, passes through the first annular air outlet, and is discharged from the air outlet above the rain shield, forming a swirling air exhaust; after the hot air is discharged, the internal air pressure of the cap-shaped cavity drops, and cold air is supplemented into the interior of the cap-shaped cavity through the air inlet on the bottom platform.

[0010] As a preferred solution, the inner side wall surface of the cap-shaped cavity is spherical crown-shaped or quasi-spherical crown-shaped.

[0011] As a preferred solution, a cap top is provided above the air outlet corresponding to the cap-shaped roof. The cap top maintains a vertical distance from the air outlet, and a second annular air outlet is formed between the periphery of the cap top and the periphery of the air outlet; when the internal air of the cap-shaped cavity expands and rises due to heat, it is discharged through the first annular air outlet, the air outlet, and the second annular air outlet.

[0030] Please refer to Figures 1 to 3 as shown, which shows the specific structure of an embodiment of the present invention.

[0031] In the description of the present invention, it should be noted that for orientation terms, such as the terms "upper", "lower", "front", "rear", "left", "right", etc., indicating the orientation and positional relationship are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present invention.

[0032] A roof cap ventilation system includes a bottom platform 10 and a cap-shaped roof 20 covering the bottom platform 10. An upwardly tapering cap-shaped cavity A is formed inside the cap-shaped roof 20. An air outlet 21 is provided at the top of the cap-shaped roof 20. A rain shield 22 is provided below the air outlet 21 in the cap-shaped cavity A. The rain shield 22 is spaced vertically from the air outlet 21, and the periphery of the rain shield 22 overlaps with the periphery of the cap-shaped roof 20 corresponding to the air outlet 21. A first annular air outlet is formed between the periphery of the rain shield 22 and the periphery of the cap-shaped roof 20 corresponding to the air outlet 21. The first annular air outlet communicates between the cap-shaped cavity A and the air outlet 21. And, the bottom platform 10 is provided with an air inlet 11 communicating the cap-shaped cavity A with the space below the bottom platform 10. Preferably, the inner side wall surface of the cap-shaped cavity A is spherical crown-shaped or quasi-spherical crown-shaped.

[0033] When the air temperature inside the cap-shaped cavity A rises, the internal air expands and rises due to heat, and is discharged from the air outlet 21 above the rain shield 22 after passing through the first annular air outlet, forming a swirling exhaust air flow. After the hot air is discharged, the internal air pressure in the cap-shaped cavity A drops, and cold air is supplemented into the interior of the cap-shaped cavity A from the air inlet 11 of the bottom platform 10. Thus, the internal and external air pressures of the cap-shaped cavity A are balanced, so as to achieve the effect of self-flow of the internal air in the cap-shaped cavity A.

[0034] A cap top 30 is provided above the air outlet 21 corresponding to the cap-shaped roof 20. The cap top 30 is spaced vertically from the air outlet 21, and a second annular air outlet is formed between the periphery of the cap top 30 and the periphery of the air outlet 21. When the air inside the cap-shaped cavity A expands and rises due to heat, it is discharged through the first annular air outlet, the air outlet 21 and the second annular air outlet.

[0035] Ventilation covers are arranged on the bottom platform 10 at intervals, and the air inlet 11 is arranged on the ventilation covers. In this embodiment, the bottom platform 10 is evenly distributed with ventilation covers at intervals of 3 meters, and the air inlet 11 is arranged on the ventilation covers. A floor 40 is provided below the bottom platform 10, and a glass curtain wall 41 is provided on the side surface of the floor 40. A lateral ventilation opening 42 is provided on the side surface of the floor 40, and, the lateral ventilation opening 42 communicates with the air inlet 11 of the bottom platform 10. In this embodiment, a glass curtain wall 41 is provided on the side surface of the floor 40, and a lateral ventilation opening 42 is provided on the glass curtain wall 41. The lateral ventilation opening 42 can adopt a louver ventilation opening.

[0036] A suspended ceiling line 43 is provided below the bottom platform 10 corresponding to the floor 40, and the lateral ventilation opening 42 is located above the suspended ceiling line 43. In this embodiment, the suspended ceiling line 43 can be fully suspended or partially suspended, and, the suspended ceiling line 43 is arranged below the bottom platform 10.

[0037] The rain shield 22 has a water collection trough 23. Among them, the water collection trough 23 is connected to a drainage system. In this embodiment, the drainage system mainly includes pipes, which can timely drain the water in the water collection trough 23 to prevent the water in the water collection trough 23 from overflowing. The drained water can be discharged as waste water, or the discharged water can be reused, for example, watering plants or reusing waste water in the washroom.

[0038] In the present invention, the roof cap ventilation system has a heat accumulation effect after being heated. The higher the temperature, the more obvious the heat accumulation effect. Next, the working principle of the present invention is described as follows:

[0039] (1) The cap top 30 and the bottom platform 10 are both designed with unsealed shapes: An air inlet 11 is provided on the bottom platform 10. Specifically, the bottom platform 10 can achieve the communication between the air inside the cap-shaped cavity A and the outdoor air through ventilation covers evenly distributed at intervals of 3 meters. In addition, the cap top 30 is communicated with the outdoor air through the air outlet 21, the first annular air outlet, and the second annular air outlet;

[0040] (2) Except for the cap top 30 and the bottom platform 10, the cap-shaped cavity A is a sealed area: When the temperature of the air inside the cap-shaped cavity A rises, under the action of the kinetic principle, the air expands when heated, becomes lighter in mass, and the hot air rises and is discharged outward through the air outlet 21, the first annular air outlet, and the second annular air outlet. After the hot air is discharged, the air pressure inside the cap-shaped cavity A drops, and cold air is supplemented into the inside of the cap-shaped cavity A from the air inlet 11 of the bottom platform 10 to achieve the balance of the internal and external air pressures. In this way, the self-flow effect of the air inside the cap-shaped cavity A is achieved; moreover, the higher the temperature, the more obvious the ventilation effect inside the cap-shaped cavity A.

[0041] The design focus of the present invention is mainly that the roof cap ventilation system passes through the bottom platform and the cap-shaped roof covering the bottom platform. An air outlet is provided at the top of the cap-shaped roof, a rain shield is provided below the air outlet in the cap-shaped cavity, and an air inlet connecting the cap-shaped cavity and the lower part of the bottom platform is provided on the bottom platform; when the temperature of the air inside the cap-shaped cavity rises, the internal air expands and rises when heated and is discharged from the air outlet, forming a vortex-shaped exhaust air; after the hot air is discharged, the air pressure inside the cap-shaped cavity drops, and cold air is supplemented into the inside of the cap-shaped cavity from the air inlet of the bottom platform to achieve the balance of the internal and external air pressures of the cap-shaped cavity and achieve the self-flow effect of the air inside the cap-shaped cavity. The settings of devices such as fans, cooling and heating, filters, and control systems in the traditional technology are omitted.
