Specific embodiments

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively exclusive embodiment from other embodiments.

[0026] Refer to Figures 1 to 3 , which is a specific embodiment of the present invention. This embodiment provides a roof automatic exhaust device, including a cylinder body 1. A plurality of ventilation holes 2 are opened on the outer wall of the cylinder body 1. An exhaust hole 11 is opened at the top of the cylinder body 1. A ventilation opening 5 is opened at the bottom of the cylinder body 1. An exhaust assembly 7 is arranged inside the cylinder body 1. The arrangement of the ventilation holes 2 facilitates the gas generated between the structural layers to flow into the cylinder body 1, thereby balancing the air pressure on the roof and avoiding the roof from bulging. By providing the ventilation opening 5, it is convenient for the gas at the structural layer to flow into the cylinder body 1. By providing the exhaust assembly 7, the gas inside the cylinder body 1 can be automatically discharged, thereby playing a role of automatic pressure relief. The exhaust assembly 7 includes a limit block 73 and an air hole cover 71. The limit block 73 is located inside the cylinder body 1. The air hole cover 71 is located above the cylinder body 1. A sliding rod 74 is provided between the limit block 73 and the air hole cover 71. The sliding rod 74 is located in the exhaust hole 11.

[0027] A spring 72 is sleeved on the sliding rod 74. The upper end of the spring 72 is fixedly connected to the inner top wall of the cylinder body 1, and the lower end of the spring 72 is fixedly connected to the upper surface of the limiting block 73. Through the cooperation of the air hole cover 71, the spring 72, the limiting block 73 and the sliding rod 74, when the air pressure in the cylinder body 1 exceeds a certain threshold, the limiting block 73 is pushed upward by the air pressure, so as to drive the air hole cover 71 to move upward through the sliding rod 74. The radius of the sliding rod 74 needs to be smaller than the radius of the exhaust hole 11 to achieve the exhaust effect. At this time, the spring 72 is compressed. When the air pressure gradually decreases, the spring 72 returns to its natural state, and then closes the exhaust hole 11. It should be noted that the threshold value at which the internal pressure of the cylinder body 1 is sufficient to push the air hole cover 71 upward matches the elastic force of the spring 72, and the elastic force of the spring 72 can prevent the limiting block 73 from rising to fit with the inner top wall of the cylinder body 1, avoiding blocking the exhaust hole 11, so as to realize the automatic opening and closing of the exhaust hole 11. The ventilation opening 5 is provided with a plurality of insertion teeth 51, and the plurality of insertion teeth 51 are arranged in a circumferential array along the ventilation opening 5. The setting of the ventilation opening 5 improves the roof exhaust efficiency. A water stop ring 3 is sleeved on the outer wall of the cylinder body 1. The water stop ring 3 is located above the ventilation hole 2. The setting of the water stop ring 3 increases the path of rainwater infiltration, thereby greatly increasing the infiltration resistance and effectively protecting the cylinder body 1 from rainwater penetration and erosion.

[0028] A plurality of stabilizing rods 4 are provided on the outer wall of the cylinder body 1. Three of the plurality of stabilizing rods 4 are in a group. One group is arranged above the ventilation hole 2, and the other group is arranged below the ventilation hole 2. And the stabilizing rods 4 in each group are arranged in a circumferential array on the outer wall of the cylinder body 1. By setting the stabilizing rods 4, the stability of the exhaust device is improved, and the situation that the exhaust device is inclined and loosened due to the acting force of the wind is avoided.

[0029] A rain cap 6 is arranged above the cylinder body 1. The rain cap 6 is fixedly connected to the upper end of the cylinder body 1 through a support frame 61. The shape of the rain cap 6 is conical or semi-spherical. The setting of the rain cap 6 plays a certain protective role for the exhaust device, preventing the exhaust device from being damaged due to the influence of the external environment.

[0030] During use, first sleeve the water stop ring 3 into the bottom end of the cylinder body 1, move it to a suitable position above the ventilation hole 2 and fix it. Then fixedly connect one group of stabilizing rods 4 to the outer wall of the cylinder body 1 above the ventilation hole 2, and then fixedly connect the other group of stabilizing rods 4 to the outer wall of the cylinder body 1 below the ventilation hole 2. After connection, place the entire cylinder body 1 on the top of the roof structural layer, and then stabilize the stabilizing rods 4. Due to the long-term influence of environmental factors on the roof, a large amount of gas is generated between the layers. The gas enters the inside of the cylinder body 1 through the ventilation opening 5 and the ventilation hole 2. When the air pressure in the cylinder body 1 exceeds a certain threshold, the air hole cover 71 will be pushed upward, thereby opening the exhaust hole 11. At this time, the spring 72 is compressed. When the air pressure gradually decreases, the spring 72 returns to its natural state, and then closes the exhaust hole 11. By this cycle, the effect of automatic exhaust and pressure relief can be achieved.

[0031] Advantages of the present utility model: By providing an exhaust assembly 7, when the air pressure in the cylinder body 1 reaches a certain threshold value, the air hole cover 71 will be lifted, and the gas will be discharged through the exhaust hole 11 to achieve the effect of automatic exhaust. When the air pressure drops below the threshold value, the air hole cover 71 will be closed to achieve the effect of automatic closing.

[0032] It should be understood that during the development of any actual implementation, in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered by the scope of the claims of the present utility model.
