Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and specifically to an air outlet device for ventilation equipment. Background Technology

[0002] In the existing field of ventilation equipment such as air conditioners and fresh air systems, air outlets are mostly made of metal (such as aluminum alloy) or plastic materials. These traditional air outlets have several drawbacks: First, the air supply method is limited, generally using downward dynamic pressure airflow, relying solely on auxiliary adjusting blades for small-range directional adjustment. This results in a small coverage area for each vent and turbulence at the vent, leading to uneven airflow. Second, the airflow is directly discharged through the pores of the rigid structure, resulting in a harsh airflow and noise, affecting the comfort of the user environment. Third, the pores of the rigid structure easily accumulate dust, making cleaning difficult. Over time, dust accumulation not only affects aesthetics but also hinders airflow. Furthermore, during summer cooling, the metal or plastic surfaces in contact with the cold airflow are prone to condensation due to temperature differences, causing dripping and disrupting the indoor environment. Finally, traditional air vents have a relatively limited range of appearances, failing to meet the aesthetic and personalized needs of modern architecture in different scenarios.

[0003] In summary, existing air outlet devices suffer from technical problems such as uneven airflow, harsh drying, and easy condensation. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an air outlet device for ventilation equipment to solve the technical problems of uneven air outlet, harsh air drying, and easy condensation in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution: This application provides an air outlet device for a ventilation system, comprising: A connecting pipe, wherein the air inlet of the connecting pipe is used to connect to the main air supply pipe; The air outlet body has a hollow frustum-shaped structure. The air inlet of the air outlet body is connected to the air outlet of the connecting pipe. The surface of the air outlet body is provided with a microporous structure. A support frame is disposed inside the air outlet body, and the support frame includes at least two annular support members, which extend at least two annular support members at intervals along the axial direction of the air outlet body. The nozzles are provided on the side wall of the air outlet body and are evenly distributed around the circumference of the air outlet body.

[0006] In some embodiments of this application, the support frame further includes a plurality of bridging connecting rods, the two ends of which are respectively connected to two adjacent annular support members.

[0007] In some embodiments of this application, the support frame further includes a plurality of transverse connecting rods and at least one longitudinal connecting rod. Each of the annular support members is equipped with at least one of the transverse connecting rods, and the transverse connecting rods extend radially along the annular support member. The two ends of the longitudinal connecting rod are respectively connected to two adjacent transverse connecting rods.

[0008] In some embodiments of this application, at least two fabric grooves are provided on the inner wall of the air outlet body, the fabric grooves being located at the top and bottom of the air outlet body respectively, and the annular support member passing through the fabric grooves.

[0009] In some embodiments of this application, each of the annular support members includes multiple flexible strips, adjacent flexible strips are detachably spliced ​​together by connectors, and the multiple flexible strips are connected end to end.

[0010] In some embodiments of this application, adjacent flexible strips are fixedly connected by one or more of bolts, male and female nails, or sleeves.

[0011] In some embodiments of this application, a plurality of nozzles are also included, the nozzles having a tapered flow guide structure, the bottom of the nozzles being embedded in the nozzle orifice.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an air outlet device for ventilation equipment to solve the technical problems of uneven air outlet, harsh air drying, and easy condensation in the prior art.

[0021] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: like Figures 1-4 As shown, this embodiment provides an air outlet device for a ventilation system, specifically an air distribution outlet with a supporting frame. The device includes a connecting pipe 1, an air outlet body 2, a supporting frame 3, and a nozzle 4.

[0022] Connecting duct 1 serves as the inlet, its dimensions matching those of the main air supply duct, such as the port size of a rigid or flexible duct, for introducing airflow. Connecting duct 1 is equipped with high-strength webbing, which facilitates tightening when connecting to the port and can be secured with screws, achieving a quick and secure connection. An external cover enhances the overall aesthetics.

[0023] The air outlet body 2 is connected to the connecting pipe 1, and the whole has a hollow frustum-shaped structure. The air outlet body 2 is made of fiber cloth with a microporous permeable structure.

[0024] The support frame 3 is disposed inside the air outlet body 2. The support frame 3 includes at least two annular support members 31, which extend at intervals along the axial direction (i.e., vertical direction) of the air outlet body 2 and are located at the upper and lower parts of the body, respectively.

[0025] The nozzle 4 is located on the side wall of the air outlet body 2, and multiple nozzles 4 are evenly distributed around the air outlet body 2 in a 360-degree circumference.

[0026] Working principle: When the airflow from the main air supply duct enters the outlet body 2 through the connecting pipe 1, a static pressure box is formed inside the outlet body 2, which has a frustum-shaped hollow structure. Part of the airflow slowly permeates through the microporous structure 21 on the surface of the fabric, forming a dense cold air film on the outer surface of the outlet body 2; the other part of the airflow is sprayed outwards through the nozzles 4 on the side wall under static pressure. The internal support frame 3 supports the fabric outlet body 2 when the fan is off (no ventilation), preventing it from collapsing.

[0027] The frustum-shaped structure acts as a static pressure chamber, ensuring gentle and continuous airflow. The cool air film formed by the 21 micropores effectively prevents condensation caused by direct contact between outside air and the fabric surface due to temperature differences, thus solving the problem of condensation in summer air supply. The 360-degree surround opening design ensures uniform airflow, covering the entire air supply area and avoiding dead zones. The internal support frame ensures that the air outlet maintains a full, aesthetically pleasing, and practical appearance in any state.

[0028] The support frame 3 in this embodiment also includes a plurality of bridging connecting rods 32. The bridging connecting rods 32 are arranged vertically, and their two ends are respectively connected to two adjacent annular support members 31.

[0029] The independent ring-shaped support components are connected into a whole cage frame by bridging connecting rods, which significantly enhances the overall stability and rigidity of the support frame and prevents the air distribution outlet from twisting or deforming under airflow disturbance.

[0030] As another form of support, the support frame 3 in this embodiment also includes a plurality of transverse connecting rods 33 and at least one longitudinal connecting rod 34. Each annular support member 31 is equipped with at least one transverse connecting rod 33, which extends radially, for example, in a cross-shaped or straight shape. The longitudinal connecting rod 34 is located on the central axis or a plurality of longitudinal connecting rods 34 are symmetrically arranged along the central axis, and their two ends are respectively connected to two adjacent transverse connecting rods 33.

[0031] This central support frame is particularly suitable for large-diameter air inlets, effectively preventing radial instability of large-span annular support components and further ensuring the stability of the overall structure.

[0032] At least two fabric grooves are sewn onto the inner wall of the air outlet body 2. The fabric grooves are located on the inner sides of the top and bottom edges of the air outlet body 2, respectively. The annular support member 31 is inserted and installed in these fabric grooves.

[0033] By using fabric grooves to fix the support components, the support frame can be installed in a concealed manner, keeping the appearance of the air outlet clean. On the other hand, the fabric grooves avoid direct friction between the metal or plastic support components and the fabric of the air outlet body, extending the service life of the fabric air outlet and making the installation positioning more accurate.

[0034] Each annular support 31 is not a single piece, but rather comprises multiple flexible strips, or flexible flat strips. These flexible strips possess a certain strength and toughness, such as elastic steel sheets or composite material flat strips. Adjacent flexible strips can be detachably joined together via connectors, and after being joined end-to-end, they bend to form a ring.

[0035] The modular flat strip design allows the large circular support frame to be broken down into multiple straight or slightly curved segments, significantly reducing packaging volume and facilitating transportation. Furthermore, on-site installation simply requires assembly to restore the circular shape, reducing construction difficulty.

[0036] The connectors between two adjacent flexible strip segments are fixedly connected using one or more of the following methods: bolts, male and female nails, or sleeves. For example, pre-drilled holes are provided at the ends of the flat strips for locking with male and female nails; or a metal sleeve is used to connect the ends of the two flat strip segments.

[0037] It uses bolts, male and female nails or sleeves for connection, which is simple in structure, strong in connection and easy to disassemble, so as to facilitate subsequent disassembly, cleaning and maintenance of the air vents or replacement of support components.

[0038] This embodiment also includes multiple nozzles 5. Each nozzle 5 has a tapered airflow guiding structure, with its bottom embedded in the nozzle 4 on the side wall of the air outlet body 2. The nozzle 5 can be a plastic injection molded part.

[0039] For applications requiring long-distance air delivery, the nozzle 5 with its conical guide structure can precisely control the airflow diffusion angle, ensuring good concentration and kinetic energy during delivery. This achieves efficient long-distance directional air delivery, reduces wind resistance loss, and ensures the stability of the air delivery range.

[0040] The device also includes a bottom cover 6. The bottom cover 6 is located at the bottom of the air outlet body 2, enclosing the bottom surface of the frustum. The bottom cover 6 and the side wall of the air outlet body 2 can be integrally sewn together, or they can be connected by a zipper.

[0041] The bottom cover seals the bottom, forcing airflow to exit primarily from the nozzles 4 and micro-holes 21 on the side walls, ensuring 360-degree lateral airflow. The zippered bottom cover also facilitates opening for internal cleaning or drainage of accumulated water.

[0042] The diameter of the multiple annular support members 31 gradually decreases from the top to the bottom of the air outlet body 2, so that the air outlet body 2 is in the shape of an inverted frustum (larger at the top and smaller at the bottom) when supported.

[0043] The inverted truncated cone shape conforms to the principles of fluid mechanics, which is conducive to the effective conversion of dynamic pressure into static pressure during the downward transmission of airflow, resulting in a more uniform internal pressure distribution and ensuring that the air outlet speed of each nozzle tends to be consistent.

[0044] The orifice size of the nozzle 4 gradually increases from the top to the bottom of the air outlet body 2, or the distribution density of the nozzle 4 gradually increases from the top to the bottom of the air outlet body 2.

[0045] Due to pressure loss along the duct, the static pressure at the end is usually lower than at the beginning. By increasing the diameter of the orifice at the bottom or increasing the density of the openings at the bottom, the decrease in flow rate caused by the pressure loss can be compensated, ensuring that the air volume at all heights above and below the entire air distribution outlet is basically the same, thus achieving uniform air supply.

[0046] The connection method of connecting pipe 1 is adapted according to the type of main pipe. When connecting to a rigid pipe, connecting pipe 1 is fixed with a pressure strip and fastening screws; when connecting to a flexible pipe, the end of connecting pipe 1 is sewn with a zipper, and it is connected to the flexible main pipe through the zipper.

[0047] By providing diverse interface options, this air outlet device can be widely adapted to ventilation duct systems of different materials; the zipper connection method greatly improves the efficiency of disassembly and assembly, making it convenient for users to regularly remove the cloth bag for cleaning, thus solving the pain point of difficult cleaning of traditional air outlets.

[0048] The connectors of the support frame 3 are covered with flexible protective sleeves, such as rubber sleeves or thickened cloth sleeves. The protective sleeves can prevent the sharp edges of bolts, male and female nails and other hard connectors from piercing or abrading the fabric of the air outlet body 2, further improving the durability and safety of the product.

[0049] A condensate drain is located at the center of the bottom cover 6 of the air outlet body 2, and the drain is connected to a one-way valve or a water collection cup. Although microporous permeation can prevent surface condensation, a small amount of water may accumulate inside under extreme high humidity or shutdown conditions. The drain device facilitates the centralized collection and treatment of internal water, preventing water droplets from dripping and polluting the environment below.

[0050] A steel wire anti-detachment rope is also installed at the connecting pipe 1. One end of the anti-detachment rope is connected to the main pipe, and the other end is connected to the support frame 3. This adds secondary safety protection to prevent the air outlet from falling off due to long-term vibration or loose connection, making it particularly suitable for high-altitude installation scenarios.

[0051] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: By combining a modular support frame with a frustum-shaped fabric bag, the problem of the fabric duct becoming shrunken and unsightly when not ventilated is not solved. The segmented splicing design also solves the transportation and installation problems of large-sized air outlets.

[0052] By utilizing the static pressure box effect of the frustum shape, the combination of microporous infiltration and 360° surrounding nozzles, a gentle air delivery with no dead angles, no turbulence, and low noise is achieved; the special aperture gradient design further ensures the uniformity of airflow throughout the entire length.

[0053] The cool air film formed by the micro-perforated air outlet completely solves the condensation problem of traditional metal air outlets; the fabric material combined with the zipper design makes the air outlet lightweight, easy to disassemble, and washable, greatly reducing cleaning and maintenance costs.

[0054] Its versatile interface design and adjustable nozzle configuration allow it to adapt to a variety of complex operating conditions, from rigid pipes to flexible hoses, and from short-distance to long-distance air delivery.

[0055] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0056] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
