Description

Technical Field

[0001] This utility model belongs to the field of heating, ventilation and air conditioning technology, and in particular relates to a heating, ventilation and air conditioning vent. Background Technology

[0002] As the terminal device of an air conditioning system, the HVAC vent is a key component connecting the ductwork to the indoor environment. It primarily serves functions such as airflow distribution, direction adjustment, and aesthetics. Its design and selection directly affect indoor airflow organization, comfort, and energy consumption. A well-configured vent system can achieve uniform airflow, reduce noise, and meet the functional needs of different spaces.

[0003] Comparing with Chinese Patent CN216281946U, a heating, ventilation, and air conditioning (HVAC) vent is disclosed, including a housing. A first ventilation plate is installed on the housing, and a second ventilation plate is located above the first ventilation plate and fixed inside the housing. Multiple diffusers are provided between the first and second ventilation plates. A partition mesh is provided below the second ventilation plate, and a mounting plate is located below the partition mesh. An aromatherapy box is placed in a placement cylinder, and a protective sheet is used to prevent dust from falling into the aromatherapy box and causing pollution. The aromatherapy box releases fragrance, which diffuses into the diffusers and flows out of the first ventilation plate with the airflow of the ventilation system, thereby eliminating air odors and improving air quality. At the same time, the placement cylinder is set on a connecting block, and the connecting block is threadedly connected to the mounting plate, which facilitates disassembly and assembly, allowing for efficient and convenient replacement of the aromatherapy box.

[0004] However, the aforementioned patents cannot cope with situations where airflow is high-speed and changes drastically, and are prone to airflow pressure fluctuations, affecting the stability and uniformity of airflow diffusion. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a heating, ventilation and air conditioning vent to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heating, ventilation, and air conditioning (HVAC) air vent includes a main body device for fixing and supporting dispersed airflow, and a flow guiding module rotatably installed within the main body device for guiding airflow and dynamically fine-tuning the airflow volume. The flow guiding module includes a rotating component for driving the airflow to rotate and guide, and an opening and closing component for centrifugal sliding fine-tuning the airflow volume is provided at the bottom of the rotating component. The rotating component includes an inner air duct, a flow guide plate is provided inside the inner air duct, a baffle plate is provided around the bottom circumference of the inner air duct, a plurality of ventilation openings and fixed supports are evenly distributed on the baffle plate, and a limiting slip ring is provided above the baffle plate. The opening and closing component includes opening and closing plates corresponding to each ventilation opening, a limiting slip flange is provided on the inner edge of the opening and closing plate, and an adjustment mechanism for elastic opening and closing to accept centrifugal force is provided on the opening and closing plate.

[0008] Furthermore: the main device includes an external air duct, a sealing sleeve is provided around the bottom circumference of the external air duct, a limiting edge is provided on the bottom surface of the external air duct, an air dispersing component is provided inside the external air duct, and a support frame is provided above the air dispersing component.

[0009] Furthermore: the air dissipation assembly includes a fixed frame installed inside the external air duct, and an air dissipation sleeve is installed below the fixed frame.

[0010] Furthermore: the fixing frame is cross-shaped, and the air diffuser sleeve is a multi-layered conical sleeve structure that diffuses outward from the center.

[0011] Furthermore: the wind deflector is circular, and the ventilation opening is a fan-shaped notch.

[0012] Furthermore, the adjustment mechanism includes a movable support fixedly disposed on one side of the opening and closing plate, a preset spring is installed on the movable support, and the two ends of the preset spring are respectively fixedly connected to the fixed support and the movable support.

[0013] Furthermore, the hinged plate is fan-shaped and made of polypropylene.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The opening and closing assembly dynamically adjusts the ventilation opening area through a centrifugal force-spring linkage mechanism (preset spring + movable support) to compensate for airflow pressure fluctuations in real time; the fan-shaped opening and closing plate made of polypropylene achieves stepless adjustment in centrifugal sliding, and the ventilation opening can automatically match the wind speed.

[0016] 2. The rotating component (internal duct + deflector) uses the airflow's own power to rotate, driving the deflector to rotate synchronously, forming an active airflow guiding effect and effectively reducing turbulence; the rotating component's moment of inertia has been optimized and can respond to wind speed changes and return to a stable state within 0.8 seconds.

[0017] 3. The fan-shaped notch of the wind deflector and the opening and closing plate form a labyrinthine airflow channel, which can maintain the air outlet direction deviation of <5° when the system pressure changes suddenly (such as when the fan starts and stops). Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 A heating, ventilation and air conditioning vent includes a main body device for fixing and supporting the dispersed airflow, and a flow guiding module rotatably installed within the main body device for guiding the airflow and dynamically fine-tuning the air volume. The flow guiding module includes a rotating component for driving the airflow to rotate and guide the airflow, and an opening and closing component for centrifugal sliding fine-tuning the air volume is provided at the bottom of the rotating component.

[0027] In this embodiment: the main device includes an external air duct 101, a sealing sleeve 102 is provided around the bottom circumference of the external air duct 101, a limiting edge 103 is provided on the bottom surface of the external air duct 101, an air diffuser assembly is provided inside the external air duct 101, and a support frame 105 is provided above the air diffuser assembly; the air diffuser assembly includes a fixing frame 104 provided inside the external air duct 101, and an air diffuser sleeve 106 is provided below the fixing frame 104; the fixing frame 104 is cross-shaped, and the air diffuser sleeve 106 is a multi-layer conical sleeve structure that diffuses outward from the center; the external air duct 101 is inserted into the opening of the HVAC pipe, and is fixed and sealed by the sealing sleeve 102. The limiting edge 103 prevents the external air duct 101 from being completely inserted into the HVAC pipe and facilitates subsequent disassembly. When there is airflow in the HVAC pipe, the airflow passes through the inner air duct 201, flows out of the external air duct 101 through the air diffuser sleeve 106 supported by the fixing frame 104, and flows to the surrounding area;

[0028] In this embodiment: the rotating component includes an inner air duct 201, which is connected to the support frame 105 via a bearing. A guide plate 202 is provided inside the inner air duct 201, and a baffle plate 203 is provided on the bottom circumference of the inner air duct 201. Several ventilation openings 204 and fixed supports 206 are evenly distributed on the baffle plate 203. A limiting slip ring 205 is provided above the baffle plate 203. The baffle plate 203 is circular, and the ventilation openings 204 are fan-shaped notches. When the airflow flows at high speed and changes drastically, the airflow pushes the inner air duct 201 to rotate under the support of the support frame 105 while passing through the inner air duct 201 through the guide plate 202, which drives the baffle plate 203 and the fixed support 206 to rotate. The fixed support 206 is used to support the preset spring 303, the ventilation openings 204 are used to fine-tune the airflow, and the limiting slip ring 205 is used to limit the sliding track of the opening and closing plate 301.

[0029] In this embodiment: the opening and closing assembly includes an opening and closing plate 301 corresponding to each of the ventilation openings 204. A limiting sliding flange 304 is provided on the inner edge of the opening and closing plate 301. An adjustment mechanism for elastic opening and closing under centrifugal force is provided on the opening and closing plate 301. The adjustment mechanism includes a movable support 302 fixedly mounted on one side of the opening and closing plate 301. A preset spring 303 is installed on the movable support 302, and both ends of the preset spring 303 are fixedly connected to a fixed support 206 and a movable support 302, respectively. The opening and closing plate 301 is fan-shaped. Made of polypropylene; when the airflow flows at high speed and changes drastically, the baffle 203 and the fixed support 206 rotate. Under the action of centrifugal force, the elastic force of the preset spring 303 on the fixed support 206 is released and changes accordingly. The movable support 302 pushes the opening and closing plate 301 to slide along the limiting slip ring 205 under the limiting slip flange 304, thereby adjusting the size of the ventilation opening 204 on the baffle 203 to finely adjust the airflow and increase the stability of the airflow flowing out of the external air duct 101 from the diffuser sleeve 106.

[0030] Working principle: The external air duct 101 is inserted into the opening of the HVAC duct, and fixed and sealed by the sealing sleeve 102. The limiting edge 103 prevents the external air duct 101 from being completely inserted into the HVAC duct and facilitates subsequent disassembly. When there is airflow in the HVAC duct, the airflow passes through the inner air duct 201, flows out of the external air duct 101 through the air diffuser sleeve 106 supported by the fixing bracket 104, and flows to the surroundings. When the airflow flows at high speed and changes drastically, the airflow is pushed by the guide plate 202 while passing through the inner air duct 201. The duct 201 rotates under the support of the support frame 105, which drives the baffle plate 203 and the fixed support 206 to rotate. Under the action of centrifugal force, the elastic force of the preset spring 303 on the fixed support 206 is released and changes accordingly. Through the movable support 302, the opening and closing plate 301 is pushed to slide along the limiting slip ring 205 under the limiting slip flange 304, thereby adjusting the size of the ventilation opening 204 on the baffle plate 203 to finely adjust the airflow and increase the stability of the airflow from the diffuser sleeve 106 to the outer duct 101.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
