Description

Technical Field

[0001] This utility model relates to a strip-shaped air vent, specifically a strip-shaped air vent mechanism with noise reduction function, belonging to the field of air conditioning vent technology. Background Technology

[0002] A linear air vent is a type of adjustable airflow outlet, consisting of a series of parallel metal plates arranged in a strip. These plates partially obstruct the airflow inlet and outlet area, thus regulating the airflow. A linear air vent typically includes the vent body, an adjustment mechanism, and a filter. The vent body, made of metal plates, is the main component and is characterized by its simple structure and easy installation. The adjustment mechanism controls the opening of the vent, thereby controlling the airflow. The filter removes dust particles from the air, improving air quality.

[0003] According to the search, a strip-shaped air outlet disclosed in CN210154037U includes an integrated air outlet and an air outlet side cover. The back of each air outlet of the integrated air outlet, i.e. the air inlet direction, also has a groove for embedding air outlet accessories. The air outlet accessories are filters or shock-absorbing silicone strips, which are respectively embedded in the grooves on the back of the air outlet to suit different application occasions.

[0004] Dust inevitably accumulates in linear air vents during use. The presence of dust not only affects airflow but also generates noise. Currently, most linear air vents are installed in the ceiling position of the air outlet using screws, which is troublesome to install and remove, and they are prone to loosening after repeated installation and removal. Utility Model Content

[0005] This utility model addresses the problem that most current linear air vents are installed on the ceiling of the air outlet using screws, which is troublesome to install and remove, and is prone to loosening after repeated installation and removal. It provides a linear air vent mechanism with noise reduction function.

[0006] The present invention achieves the above objectives through the following technical solution: a strip-shaped air outlet mechanism with noise reduction function, including an air outlet bracket, and an angle adjustment component and a disassembly component located inside the air outlet bracket;

[0007] The easy-to-disassemble component includes a support worm gear that runs through the interior of the air outlet bracket. A knob is fixedly installed at one end of the support worm gear. A transmission worm wheel is meshed with one side of the support worm gear. An adjusting screw is fixedly installed inside the transmission worm wheel. The surface of the adjusting screw is connected to mounting blocks that run through the upper and lower sides of the air outlet bracket via a screw nut.

[0008] As a further improvement of this utility model: an air outlet bracket is externally mounted on an air outlet ceiling fixed to the ceiling. A sealing strip is affixed to the connection between the air outlet ceiling and the air outlet bracket. The sealing strip is located between the air outlet ceiling and the air outlet bracket to seal the air outlet bracket. The sealing strip is made of elastic material. When the airflow passes through the air outlet bracket, it can generate vibration, and the sealing strip plays a certain buffering role.

[0009] As a further improvement of this utility model: the width of the air outlet ceiling is adapted to the size of the air outlet bracket, and the mounting block fits against the inner wall of the air outlet ceiling. The mounting block can be locked on one side of the inner wall of the air outlet ceiling, which facilitates the installation of the air outlet bracket.

[0010] As a further improvement of this utility model: the angle adjustment component includes multiple air outlet blades that are rotatably installed inside the air outlet bracket. The left and right ends of the air outlet blades are fixedly provided with rotating shafts. The rotating air outlet blades can be adjusted in angle as needed to facilitate the adjustment of the air outlet direction.

[0011] As a further improvement of this utility model: an adjusting worm gear is fixedly installed on the outside of the rotating shaft, and an adjusting worm is meshed with one side of the adjusting worm gear. The rotating adjusting worm can drive the adjusting worm gear to rotate, thereby driving the air outlet blades to rotate through the rotating shaft.

[0012] As a further embodiment of this utility model: a transmission shaft is fixedly connected between the adjusting worm gears, and a stepper motor power output end is fixedly installed on the top of one set of transmission shafts. The stepper motor can drive the transmission shaft to rotate, thereby driving the adjusting worm gear to rotate synchronously through the transmission shaft.

[0013] As a further improvement of this utility model: a filter screen is provided at the rear end of the air outlet blade, and sound-absorbing cotton is pasted on both the upper and lower sides of the air outlet blade. The sound-absorbing cotton is fixed on the upper and lower sides of the air outlet blade to play a certain sound absorption role.

[0014] The beneficial effects of this utility model are:

[0015] The easy-to-disassemble component allows the transmission worm gear to rotate by turning the knob. When the transmission worm gear rotates, the mounting blocks can move up and down by rotating the adjusting screw. The adjusting screw is a two-way screw, which can simultaneously drive two sets of mounting blocks to move in opposite directions, so that the mounting blocks are locked inside the ceiling of the air outlet, making it easy to disassemble and assemble the air outlet bracket. The self-locking function of the transmission worm gear and the support worm can limit the mounting blocks.

[0016] The angle adjustment component allows the air outlet blades to rotate, enabling angle adjustments as needed to easily control the airflow direction. The sound-absorbing cotton on the air outlet blades, combined with the sealing strip, provides a certain degree of noise reduction. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0023] like Figures 1 to 4 As shown, a strip-shaped air outlet mechanism with noise reduction function includes an air outlet bracket 1, an angle adjustment component 2 and a detachable component 3 located inside the air outlet bracket 1.

[0024] The easy-to-disassemble component 3 includes a support worm gear 305 that passes through the interior of the air outlet bracket 1. A knob 301 is fixedly installed at one end of the support worm gear 305. A transmission worm wheel 302 is meshed with one side of the support worm gear 305. An adjusting screw 303 is fixedly installed inside the transmission worm wheel 302. The surface of the adjusting screw 303 is connected to mounting blocks 304 that pass through the upper and lower sides of the air outlet bracket 1 via a screw nut. The transmission worm wheel 302 can be rotated by rotating the knob 301. When the transmission worm wheel 302 rotates, the mounting blocks 304 can be moved up and down by rotating the adjusting screw 303. The adjusting screw 303 is a bidirectional screw, which can simultaneously drive two sets of mounting blocks 304 to move in opposite directions, so that the mounting blocks 304 are locked inside the air outlet ceiling 4, which facilitates the disassembly and assembly of the air outlet bracket 1. The mounting blocks 304 are limited by the self-locking function of the transmission worm wheel 302 and the support worm gear 305. Example 2

[0025] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] An air outlet bracket 1 is externally mounted on an air outlet ceiling 4 fixed to the ceiling. A sealing strip 5 is affixed to the connection between the air outlet ceiling 4 and the air outlet bracket 1. The sealing strip 5 is located between the air outlet ceiling 4 and the air outlet bracket 1 to seal the air outlet bracket 1. The sealing strip 5 is made of elastic material. When the airflow passes through the air outlet bracket 1, it can generate vibration, and the sealing strip 5 plays a certain buffering role.

[0027] The width of the air outlet ceiling 4 is matched with the size of the air outlet bracket 1, and the mounting block 304 fits into the inner wall of the air outlet ceiling 4. The mounting block 304 can be clipped onto one side of the inner wall of the air outlet ceiling 4, which facilitates the installation of the air outlet bracket 1. Example 3

[0028] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0029] The angle adjustment component 2 includes multiple air outlet blades 201 that are rotatably installed inside the air outlet bracket 1. The left and right ends of the air outlet blades 201 are fixedly provided with rotating shafts 204. The rotating air outlet blades 201 can be adjusted in angle as needed to facilitate the adjustment of the air outlet direction.

[0030] An adjusting worm gear 205 is fixedly installed on the outside of the rotating shaft 204. An adjusting worm 206 is meshed with one side of the adjusting worm gear 205. The rotating adjusting worm 206 can drive the adjusting worm gear 205 to rotate, thereby driving the air outlet blade 201 to rotate through the rotating shaft 204.

[0031] A drive shaft 203 is fixedly connected between the adjusting worm gears 206. The top of one set of drive shafts 203 is fixedly provided with the power output end of a stepper motor 207. The stepper motor 207 can drive the drive shafts 203 to rotate, thereby driving the adjusting worm gears 206 to rotate synchronously through the drive shafts 203.

[0032] A filter screen 6 is provided at the rear end of the air outlet blade 201. Sound-absorbing cotton 202 is attached to both the upper and lower sides of the air outlet blade 201. The sound-absorbing cotton 202 is fixed to the upper and lower sides of the air outlet blade 201 and plays a certain role in sound absorption.

[0033] Working principle: When using the strip-shaped air vent mechanism with noise reduction function, the air vent bracket 1 is inserted into the interior of the air vent ceiling 4 and is tightly pressed against the sealing strip 5. Rotating the knob 301 drives the transmission worm gear 302 to rotate. When the transmission worm gear 302 rotates, it can drive the mounting block 304 to move up and down through the rotating adjusting screw 303. The adjusting screw 303 is a two-way screw, which can simultaneously drive two sets of mounting blocks 304 to move in opposite directions, so that the mounting blocks 304 are locked inside the air vent ceiling 4, which facilitates the disassembly and assembly of the air vent bracket 1. Furthermore, through the transmission worm gear 302 and the support... The self-locking function of the worm gear 305 limits the installation block 304. When the angle of the air outlet blade 201 needs to be adjusted, the stepper motor 207 can drive the transmission shaft 203 to rotate, thereby driving the adjusting worm gear 206 to rotate synchronously through the transmission shaft 203. The rotating adjusting worm gear 206 can drive the adjusting worm wheel 205 to rotate, thereby driving the air outlet blade 201 to rotate through the rotating shaft 204, so that the angle can be adjusted as needed, and the air outlet direction can be adjusted. The sound-absorbing cotton 202 is set on the air outlet blade 201, which, together with the sealing strip 5, can play a certain noise reduction role.
