Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to an adjustable diffuser air outlet device. Background Technology

[0002] As a key terminal component in building ventilation and air conditioning systems, diffuser vents are widely used in office buildings, shopping malls, hospitals and other places. Their main function is to evenly deliver air with regulated temperature and humidity into the room to create a comfortable indoor environment.

[0003] In existing technologies, in order to adapt to different indoor load changes and the comfort needs of people, the air volume of the air outlet must be adjusted. However, many conventional diffuser air outlet devices are insufficient in terms of air volume adjustment. The air volume of some products is fixed and cannot be adjusted according to actual needs, resulting in poor flexibility. Although other products provide adjustment functions, the adjustment methods are often primitive and inconvenient. For example, it is necessary to manually operate valves or baffles hidden at high places with the help of ladders or other tools. The operation process is cumbersome and has certain dangers, making it difficult to meet the user's need for convenient and immediate adjustment.

[0004] Furthermore, to ensure indoor air quality, air vents are usually equipped with filters to intercept dust and impurities in the air. Over time, the filters will gradually become clogged and need to be cleaned or replaced regularly. However, many existing air vent devices are not designed with ease of maintenance in mind. The process of removing and installing filters is often very complicated, requiring the use of tools such as screwdrivers to remove the entire panel or multiple fasteners to take out the filters. This not only makes daily maintenance time-consuming and laborious, but also leads to problems such as reduced air supply efficiency, increased energy consumption, and secondary indoor air pollution due to untimely maintenance.

[0005] Therefore, this utility model proposes an adjustable diffuser air outlet device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the diffuser air outlet device, such as inconvenient wind speed adjustment, cumbersome and laborious filter replacement process, and loosening and displacement due to airflow impact after installation, this utility model aims to provide an adjustable diffuser air outlet device with improved structure that can effectively solve the above problems.

[0007] This utility model provides an adjustable diffuser air outlet device, including: an air outlet frame that defines the internal airflow channel, and an integrated adjustment mechanism and a connecting mechanism.

[0008] The adjustment mechanism includes a motor connected to the rotating blade and an adjuster for controlling the motor. The air outlet frame is also connected to a locking structure consisting of a rotatable locking plate and a positioning pin for fixing the replaceable filter screen. The connection mechanism includes a fixing bracket welded to the air outlet frame and a positioning block used with screws and nuts.

[0009] Furthermore, the adjustment mechanism, the locking structure, and the connecting mechanism are combined in the following manner: the motor is fixed to the outside of the air outlet frame, the output shaft passes through the air outlet frame and is connected to the rotating blade rotatably disposed in the airflow channel; the regulator is installed on the outside of the air outlet frame and electrically connected to the motor; the locking plate is pivotally connected to the air outlet frame through the connecting shaft and locked by the positioning pin; the fixing frame is welded to the outer wall of the air outlet frame and connected to the external mounting surface by screws and nuts passing through the positioning block.

[0010] Preferably, the adjustment mechanism further includes multiple louvers evenly distributed in the ventilation area of ​​the air vent frame.

[0011] Preferably, the adjustment mechanism further includes an air suction plate that is tilted and fixed to the front side of the air inlet end of the air vent frame.

[0012] Preferably, the motor is specifically fixed on the left side outside the air vent frame.

[0013] Preferably, the regulator is installed on the side of the outer side of the air outlet frame and is used to control the speed of the motor to adjust the wind speed.

[0014] Preferably, the locking plate rotates via the connecting shaft to selectively cover or clear the installation position of the replacement filter, and the positioning pin can be inserted and removed through the locking plate and engages with the air vent frame to lock the locking plate.

[0015] Preferably, one side of the fixing frame is welded to the opposite ends of the outer side of the air vent frame.

[0016] Preferably, the positioning block has a contact surface that matches the outer wall of the air vent frame, and fits against the outer wall of the air vent frame when the screws and nuts are tightened, thus playing a positioning role.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of fixed or inconvenient airflow speed at the air outlet and complicated, time-consuming and labor-intensive filter cleaning and replacement processes in the prior art by setting an adjustment mechanism that drives the rotating blades by a motor and controls the speed by an external regulator, and by setting a quick-release and disassembly structure for the filter screen consisting of a positioning pin and a rotatable locking plate. It enables convenient adjustment of airflow speed as needed, greatly simplifies filter screen maintenance operations, and improves the convenience of use and maintenance.

[0018] 2. This utility model solves the problem that the existing air outlet device relies solely on simple screws for fixing, which can loosen or shift due to long-term airflow impact, resulting in structural instability. By setting up a connecting mechanism that includes a fixing frame welded to the air outlet frame and a positioning block for precise positioning, the device is installed stably and reliably and will not shift after long-term use.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 4This utility model provides an adjustable diffuser air outlet device, including an air outlet frame 1 that defines an internal airflow channel. The air outlet frame 1 integrates an adjustment mechanism 2 and a connecting mechanism 3. The adjustment mechanism 2 is used to adjust and filter the airflow, and the connecting mechanism 3 is used to stably fix the entire device to the external mounting surface. Specifically, multiple louvers 23 are evenly distributed in the ventilation area of ​​the air outlet frame 1. An air intake plate 25 is obliquely and fixedly connected to the front side of the air inlet end of the air outlet frame 1. The air outlet frame 1 also has a locking structure for quick installation and removal of a replaceable filter screen 26, including a connecting shaft 27, a locking plate 28 pivotally connected to the air outlet frame 1 via the connecting shaft 27, and a locking mechanism. The positioning pin 29 of the fixed plate 28, the adjustment mechanism 2 also includes a motor 21 fixed on the left side of the outside of the air outlet frame 1, and a rotating blade 22 rotatably disposed inside the airflow channel. The output shaft of the motor 21 passes through the air outlet frame 1 and is fixedly connected to one end of the rotating blade 22. The adjustment mechanism 2 also includes an adjuster 24 installed on the outer side of the air outlet frame 1. The adjuster 24 is electrically connected to the motor 21. The connection mechanism 3 includes a fixing bracket 31 fixedly connected to the opposite ends of the outside of the air outlet frame 1 by welding on one side, and a positioning block 32 having a contact surface that matches the outer wall of the air outlet frame 1. The other side of the fixing bracket 31 passes through the positioning block 32 by screws 33 and is locked by nuts 34.

[0023] Please refer to Figures 1 to 4The motor 21 is fixedly installed on the outer left side of the air vent frame 1. The output shaft of the motor 21 passes through the wall panel of the air vent frame 1 and is fixedly connected to one end of the rotating blade 22. The rotating blade 22 is rotatably installed in the internal airflow channel of the air vent frame 1. When the motor 21 is powered on, it drives the rotating blade 22 to rotate at high speed in the airflow channel, thereby pushing and diffusing the passing airflow. The regulator 24, installed on the outer side of the air vent frame 1, is electrically connected to the motor 21. The regulator 24 can control the electrical energy parameters supplied to the motor 21, thereby precisely adjusting the speed of the motor 21, allowing the user to easily adjust the wind speed. The locking plate 28 is pivotally connected to the air vent frame 1 through the connecting shaft 27, allowing the locking plate 28 to rotate freely around the axis of the connecting shaft 27. The positioning pin 29 can be inserted and removed through the locking plate 28 and cooperates with the air vent frame 1. In the locked state, the positioning pin 29 can reliably restrict the locking plate 28. The rotating mechanism presses and secures the replaceable filter 26 to its mounting position on the air vent frame 1. When the filter 26 needs to be removed and replaced, simply pull out the positioning pin 29, and then manually push the locking plate 28 to rotate around the connecting shaft 27, thus completely opening up the installation space for the replaceable filter 26 and enabling quick removal and replacement of the filter 26. Finally, for the connecting mechanism 3 that ensures a stable installation, the fixing bracket 31 is firmly fixed to the opposite ends of the outer wall of the air vent frame 1 by welding. The positioning block 32 has a contact surface that matches the outer wall of the air vent frame 1. During installation, the positioning block 32 fits against the outer wall of the air vent frame 1, playing a precise positioning role and preventing the air vent frame 1 from shifting position during installation. The screw 33 passes through the mounting hole of the fixing bracket 31 and the through hole of the positioning block 32 in sequence, and finally forms a threaded engagement with the nut 34 to lock it, ensuring that the entire device can be stably installed on the external mounting surface and effectively resisting vibration or displacement caused by airflow impact.

[0024] As a preferred embodiment, in order to better disperse and guide the airflow, multiple louvered fans 23 are evenly fixedly connected in the ventilation area of ​​the air outlet frame 1. The arrangement of the louvered fans 23 helps to further comb and diffuse the airflow sent from the rotating blades 22, making the airflow more uniform and gentle.

[0025] As another preferred embodiment, in order to more effectively guide the external airflow into the device, an air suction plate 25 is installed on the front side of the air inlet end of the air outlet frame 1 by a fixed connection. The air suction plate 25 is inclined and can smoothly guide the air from the external environment into the filtration area where the replaceable filter screen 26 is located.

[0026] As a specific installation layout, the motor 21 is preferably fixed on the left side outside the air vent frame 1, while the regulator 24 is correspondingly installed on the side outside the air vent frame 1. This layout makes the electric drive part and the manual control part clearly separated, which is convenient for user operation and wiring.

[0027] In a more specific implementation of the locking structure, the locking plate 28 can selectively cover or allow the installation position of the replaceable filter 26 by rotating about the connecting shaft 27. When it is necessary to fix the replaceable filter 26, the locking plate 28 is rotated to the covered position, and then the positioning pin 29 is inserted and detachably passed through the locking plate 28 and engaged with the air outlet frame 1, thereby reliably locking the locking plate 28 by means of the positioning pin 29.

[0028] As a preferred installation method for the connection mechanism 3, one side of the fixing frame 31 is fixedly connected to the opposite ends of the outer wall of the air outlet frame 1 by welding, which provides a symmetrical and stable installation base for the device.

[0029] Working principle: When the device needs to be installed, the air outlet frame 1 is first placed in the preset installation position. Since the positioning block 32 has a contact surface that matches the outer wall of the air outlet frame 1, the positioning block 32 can fit tightly against the outer wall of the air outlet frame 1, playing a precise positioning role. Then, the screw 33 is passed through the fixing frame 31 and the positioning block 32 welded to the outside of the air outlet frame 1 in sequence, and the nut 34 is used to tighten the thread from the other side. Through the synergistic action of the fixing frame 31, the positioning block 32, the screw 33 and the nut 34, the connecting mechanism 3 can firmly fix the entire air outlet frame 1 to the external installation surface, effectively preventing the device from shifting position or vibrating due to airflow impact, and ensuring the stability of operation. When the device is put into use, the external airflow is first smoothly guided into the air inlet end of the air outlet frame 1 by the inclined suction plate 25. Then, the airflow passes through the replaceable filter 26 installed on the snap-fit ​​structure. Dust, impurities and other particles in the airflow are effectively intercepted and filtered by the replaceable filter 26, thus obtaining clean air. At this time, the user can operate the regulator 24 installed on the outer side of the air outlet frame 1. The regulator 24 controls the operation of the motor 21 through electrical connection. After starting, the motor 21 drives the rotating blades 22 installed in the airflow channel inside the air outlet frame 1 to rotate at high speed. The rotating blades 22 forcefully push the filtered clean air and guide the airflow to the evenly distributed louvers 23. The louvers 23 perform secondary diffusion and combing of the airflow, ultimately forming a uniform and gentle air delivery effect. When the user needs to adjust the wind speed, he only needs to operate the regulator 24 to change the speed of the motor 21, thereby realizing stepless or step-by-step adjustment of the air delivery speed to meet the needs of different scenarios. When the filter 26 needs cleaning or replacement due to prolonged use, the maintenance process is very convenient. Simply pull the positioning pin 29 off the locking plate 28 by hand to release the locking plate 28, and then push the locking plate 28 around the connecting shaft 27 by hand to completely open the installation area of ​​the replaceable filter 26. At this time, the replaceable filter 26 can be easily removed from the air outlet frame 1. After cleaning or replacing the new replaceable filter 26, reverse the operation to place the replaceable filter 26 back in its original position, rotate the locking plate 28 to the covering position, and finally insert the positioning pin 29 to complete the fixation. No complicated tools are required, the operation is simple and quick, and the maintenance efficiency of the device is improved.
