Description

Technical Field

[0001] The present application relates to the technical field of smoke exhaust pipes, and in particular to a building ventilation flue. Background Art

[0002] With the continuous progress of society and the acceleration of urbanization, the construction industry has flourished, providing people with a safer, more comfortable and convenient living environment. When building a house, the ventilation flue, as an important component, plays a vital role in ensuring indoor air quality and the health of residents. Ventilation flues, especially residential flues, are key facilities for removing kitchen fumes and bathroom exhaust gas. Their design and application are particularly critical, especially in high-rise buildings, where their importance is self-evident.

[0003] Traditional flue ventilation can be divided into two types: natural ventilation and mechanical ventilation. For example, the existing building ventilation flue with a publication number of CN218508919U (China, the authorization announcement date is 20230221), in the above scheme, includes a flue body, the flue body is a rectangular body with hollow top and bottom ends, two sets of support plates are fixedly installed on the top wall of the flue body, and the top wall of the two sets of support plates is commonly connected with a top cover plate, and a slide groove is provided on the two opposite walls in the hollow of the flue body, and an oil suction mechanism is provided in the hollow of the flue body. By arranging an oil suction mechanism in the cavity of the flue body, the oil smoke in the inner cavity of the flue body can be adsorbed, the oil stains flow into the oil storage box along the inclined plate, and the smoke is discharged upward from the fine holes on the inclined plate. The scraper can scrape the inner cavity wall of the flue body, so that the smoke discharged from the inner wall of the flue body reduces the pollution to the environment, and the practicality of the device is improved through reasonable structural design. However, this design still has certain problems and challenges in practical applications. First, since the flue needs to be interspersed between the floors of the building, each floor has an opening, which to some extent affects the chimney effect of the flue, that is, using the principle of hot air rising to promote the discharge of exhaust gas. This design may lead to insufficient buoyancy, especially for low-rise residents, who are more likely to encounter the problem of poor smoke exhaust. Secondly, if the height of the flue extending out of the roof is designed too low, it will not only be difficult to meet the structural requirements such as waterproofing, but it will also be easy for the exhausted gas to be affected by wind pressure and flow back into the room, causing adverse effects on the living environment of the residents, especially the top-floor users are more susceptible to such problems. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a building ventilation flue to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0010] Furthermore, the inner top of the top cover and the top ends of the two connecting rods are integrally formed and provided with an arc groove.

[0011] Furthermore, the cleaning mechanism includes a load-bearing rod, a chain-collecting motor, a chain, a hook, a lifting ring and a scraper box.

This design combines the air supply function of the blower, and the blower delivers wind into the smoke exhaust pipe, effectively promoting the flow of exhaust gas inside the smoke exhaust pipe to be smoother. This layout not only significantly improves the smoke exhaust effect and ensures the efficient discharge of exhaust gas, but also effectively solves the problem of gas backflow into the room, providing a safer and healthier guarantee for the internal environment of the building.

[0015] 2. The utility model effectively prevents rainwater from entering the smoke exhaust duct by introducing the rainproof roof, thereby ensuring the normal operation of the smoke duct in bad weather.

The top of the scraper box is in the shape of a blade and fits tightly with the inner wall of the exhaust pipe. This design ensures that more dirt can be scraped off during cleaning, improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] 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. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Example:

[0026] See also Figure 1 , Figure 4 , Figure 5 A building ventilation flue comprises a smoke exhaust pipe 1 and a cleaning mechanism 3 slidably connected inside the smoke exhaust pipe 1; the cleaning mechanism 3 comprises a bearing rod 31, a chain motor 32, a chain 33, a hook 34, a ring 35 and a scraper box 36.

[0027] The smoke exhaust pipe 1 is the main part of the ventilation flue, and its design takes into account the exhaust gas emission efficiency and the structural strength of the flue, and is provided with reinforcing ribs inside. In high-rise buildings, the smoke exhaust pipe 1 has a certain pressure resistance to ensure that it will not be deformed or damaged under the action of wind pressure and the pressure of the building itself.

[0028] Among them, the cleaning mechanism 3 can efficiently clean the oil and dust in the smoke exhaust pipe 1. The bearing rod 31 serves as the main supporting structure of the cleaning mechanism 3, and the two ends of the bearing rod 31 are firmly connected to the opposite ends of the two connecting rods 232 by bolts. This connection method not only ensures the stability of the structure, but also facilitates installation and disassembly. The chain motor 32 serves as the power source of the cleaning mechanism 3, and the top of the chain motor 32 is connected to the bearing rod 31 by a hook. A driving mechanism of the chain 33 is provided inside the motor, which can accurately control the retraction and release of the chain 33. The chain 33 serves as a transmission component, and one end of the chain 33 is connected to the output shaft of the chain motor 32, and the other end is fixedly connected to the hook 34. The selection of the chain 33 should ensure sufficient strength and wear resistance to cope with frequent operation and long-term use. The lifting ring 35 is welded to the inner bottom of the scraper box 36. The hook 34 is connected to the lifting ring 35 by a hook, so that the scraper box 36 can move up and down with the retraction and release of the chain 33. The scraper box 36 is the core component of the cleaning mechanism 3. The outer wall of the scraper box 36 fits tightly with the inner wall of the smoke exhaust pipe 1. The top is designed to be blade-shaped, which can enhance the fit between the scraper box 36 and the inner wall of the smoke exhaust pipe 1 and improve the cleaning effect. Driven by the chain 33, the scraper box 36 can slide up and down along the inner wall of the smoke exhaust pipe 1 to scrape off the oil and dust attached to the inner wall of the pipe.

[0029] See also Figure 1 , Figure 2 , Figure 3 A building ventilation flue, a smoke exhaust pipe 1 having an outer wall fixedly connected to a smoke delivery mechanism 2, the smoke delivery mechanism 2 is composed of a plurality of smoke exhaust components 21, a blower 22 and a rain shield 23; the smoke exhaust component 21 includes a guide pipe 211, a connecting frame 212 and a plurality of mounting holes 213; the rain shield 23 includes a top cover 231 and two connecting rods 232.

[0030] Among them, the smoke exhaust part 21 is uniquely designed. Through the inclined layout of the guide pipe 211 and the close connection with the smoke exhaust pipe 1, the smoke exhaust efficiency is effectively improved, and the exhaust gas rises naturally. One end of the guide pipe 211 is fixedly connected to the inner end of the connecting frame 212, and the other end is fixedly connected to the outer wall of the smoke exhaust pipe 1 at an inclined angle. This inclined design can ensure that the exhaust gas flows to the smoke exhaust pipe 1 more smoothly, thereby improving the smoke exhaust efficiency. The connecting frame 212 is located at one end of the guide pipe 211 and is fixedly connected to the inner end of the guide pipe 211. A number of mounting holes 213 are evenly spaced at the outer end of the connecting frame 212. These mounting holes 213 are used to fix the smoke exhaust part 21 on the building structure to ensure the stability and safety of the smoke exhaust part 21. The mounting holes 213 are opened at the outer end of the connecting frame 212 and are evenly spaced. These mounting holes 213 can be selected and adjusted according to actual installation requirements to adapt to different building structures and installation environments.

[0031] The two ends of the guide pipe 211 are respectively formed integrally with the inner end of the connection frame 212 and the outer wall of the smoke exhaust pipe 1. This one-piece manufacturing method not only improves the overall strength and stability of the smoke exhaust member 21, but also simplifies the manufacturing process and reduces the manufacturing cost, making the entire structure more stable and reliable, and not prone to deformation or damage.

[0032] Among them, the blower 22 is installed on the outer wall of the smoke exhaust duct 1, and its air supply end is connected to the bottom side of the smoke exhaust duct 1. This installation position selection ensures that the blower 22 can directly send air into the bottom of the smoke exhaust duct 1, thereby more effectively pushing the exhaust gas to rise and discharge. The blower 22 is connected to the outer wall of the smoke exhaust duct 1 with bolts. This connection method is not only firm and reliable, but also easy to install and disassemble. During the installation process, the angle and position of the blower 22 can be adjusted according to actual needs to ensure that the connection between it and the smoke exhaust duct 1 is tight and stable. The air supply direction of the blower 22 is consistent with the smoke exhaust direction of the smoke exhaust duct 1, which can effectively prevent outdoor air or other gases from flowing back into the room, ensuring the comfort of the indoor environment.

[0033] Among them, the rain shield 23 can effectively prevent rainwater and other external objects from entering the smoke exhaust duct 1, and protect the integrity of the internal structure of the flue and the normal operation of the function. The top sides of the inner top of the top cover 231 are fixedly connected to the tops of the two connecting rods 232 respectively. The shape and size of the top cover 231 are designed according to the actual situation of the smoke exhaust duct 1 to ensure that the top of the smoke exhaust duct 1 can be effectively shielded. At the same time, the inner top of the top cover 231 and the tops of the two connecting rods 232 are integrally formed. This structural design enhances the overall strength and stability of the rain shield 23. The connecting rod 232 is located between the top cover 231 and the smoke exhaust duct 1. The function of the connecting rod 232 is to connect the top cover 231 and the smoke exhaust duct 1, and to firmly install the rain shield 23 on the top of the smoke exhaust duct 1. It is not easy to shake or fall off.

[0034] The working principle of the building ventilation flue is as follows: when exhausting smoke, first make sure that the scraper box 36 is located at the bottom of the exhaust pipe 1 and is lower than the air outlet of the blower 22, start the blower 22, and connect its air outlet to the bottom side of the exhaust pipe 1. This ensures that the blower 22 can directly send air into the bottom of the exhaust pipe 1, thereby more effectively pushing the exhaust gas up and out. At this time, the exhaust gas is quickly exhausted into the exhaust pipe 1 through the inclined exhaust member 21.

[0035] It should be noted that the specific models and specifications of the chain collecting motor 32, the scraper box 36, and the guide pipe 211 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the chain retracting motor 32 are clear to those skilled in the art and will not be described in detail here.

[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
