Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to an air conditioning vent adjustment device. Background Technology

[0002] Air conditioning has become a major electrical appliance for heating or cooling, and with the improvement of people's living standards, it has entered thousands of households. The main types of air conditioners are: floor-standing air conditioners, wall-mounted air conditioners, water-cooled air conditioners, and central air conditioning systems. Central air conditioning systems are more widely used in some public places.

[0003] Central air conditioning systems mainly consist of a refrigeration unit, a cooling water circulation system, and a chilled water circulation system. The cold air generated by the refrigeration unit is delivered to the interior space through air ducts to achieve cooling. However, due to the strong airflow of central air conditioning systems, in existing technology, the air outlets of the air ducts are at a fixed angle. Prolonged directional airflow is detrimental to temperature balance within the space and may cause discomfort due to prolonged direct airflow onto occupants. Therefore, in practical use, to address these issues, devices for adjusting the airflow angle are often added to the air outlets of the air ducts.

[0004] The related technology describes a device for adjusting the air supply angle, which includes an adjusting grille. The adjusting grille is installed at the air outlet, and the air supply angle of the central air conditioner is changed by adjusting the tilt angle of the baffles in the adjusting grille. However, the adjusting grille needs to be adjusted manually. Since central air conditioners are generally installed on the ceiling, which is relatively high above the ground, this is inconvenient to operate and also prevents continuous adjustment of the air supply angle. Summary of the Invention

[0005] In order to achieve continuous automatic adjustment of the air direction at the air outlet of the air supply duct to improve the air supply effect, this application provides an air conditioning vent air direction adjustment device.

[0006] The air conditioning vent direction adjustment device provided in this application adopts the following technical solution: An air conditioning vent air direction adjustment device includes a fixed plate, a rotating roller, a transmission mechanism, a drive rod, and a swing assembly. The swing assembly includes a connecting pipe. Two fixed plates are provided, each installed on one side of an air supply duct. The two ends of the rotating roller are rotatably connected to the two fixed plates. The rotating roller is provided with fan blades, which are arranged along the length of the rotating roller. An opening is provided in the air supply duct for the fan blades to extend into the air supply duct. The end of the rotating roller is connected to the transmission mechanism. One end of the connecting pipe is connected to the air supply duct. The connecting pipe is a flexible pipe. The drive rod is rotatably connected to the fixed plate via a rotating shaft. One end of the drive rod is rotatably connected to the connecting pipe, and the other end of the drive rod is connected to the transmission mechanism. When the rotating roller rotates, the transmission mechanism can drive the drive rod to rotate around the rotating shaft.

[0007] By adopting the above technical solution, after the central air conditioning is started, the generated cold air is sequentially delivered into the required space through the air supply duct and connecting pipe. Since the fan blades are located in the flow path of the cold air, the cold air blows the fan blades, which in turn drives the rotating roller to rotate. Through the transmission mechanism, the drive rod can be driven to rotate continuously. Under the action of the drive rod, the end of the connecting pipe away from the air supply duct can swing to adjust the air supply angle. In this way, through the cooperation of the rotating roller, transmission mechanism and drive rod, the air supply direction can be continuously and automatically changed, thereby achieving a wider air supply angle and better air supply effect. At the same time, it directly uses the cold air generated by the central air conditioning itself as the driving source, without the need for additional driving equipment, which can greatly reduce costs.

[0008] Optionally, the transmission mechanism includes a driving gear and a driven gear. The driving gear is fixedly connected to the rotating roller, and the driven gear is rotatably connected to the fixed plate. The driving gear and the driven gear mesh. A protrusion is formed on the driven gear, and a limiting groove is provided on the drive rod for the protrusion to be inserted. The limiting groove is arranged along the length direction of the drive rod, and the protrusion can slide in the limiting groove.

[0009] By adopting the above technical solution, the rotating roller drives the active gear to rotate, and the active gear in turn drives the driven gear to rotate. Through the cooperation of the protrusion, the driven gear and the limiting groove, the end of the connecting pipe away from the air supply pipe can achieve continuous reciprocating oscillation, which improves the air supply effect.

[0010] Optionally, the driven gear has a larger diameter than the driving gear, and the protrusion is located near the edge of the driven gear.

[0011] By adopting the above technical solution, the rotational speed of the driven gear is much smaller than that of the driving gear, the swing of the connecting tube is more stable, and the setting of the protrusion can maximize the swing angle of the connecting tube.

[0012] Optionally, it also includes a housing, which is fitted onto the air supply duct and the connecting pipe, and the end of the housing away from the air supply duct is formed with a fan-shaped vent.

[0013] By adopting the above technical solution, the casing can protect the air supply duct, connecting pipe, transmission mechanism, etc.

[0014] Optionally, it also includes an auxiliary gear, which is rotatably connected to the drive rod and mounted on the end of the drive rod away from the driven gear. The housing has an arc-shaped auxiliary guide groove, and multiple protruding teeth are machined in the auxiliary guide groove, each of which can mesh with the auxiliary gear.

[0015] By adopting the above technical solution, the stability of the connecting pipe during its swing process can be improved through the cooperation of auxiliary gears and auxiliary guide grooves, thereby achieving more stable air delivery.

[0016] Optionally, there are two transmission mechanisms and two drive rods, with the two drive rods located on both sides of the connecting pipe. The drive rods and the transmission mechanism are arranged in a one-to-one correspondence, and the rotating roller can drive the two drive rods to rotate synchronously through the transmission mechanism.

[0017] By adopting the above technical solution, the force can be uniform during the swinging process of the connecting pipe, and the stability of the connecting pipe during swinging can be improved.

[0018] Optionally, the fan blades are provided in multiples, and the multiple fan blades are distributed at intervals along the circumference of the rotating roller.

[0019] By adopting the above technical solution, the effect of continuous oscillation of the connecting pipe can be further improved.

[0020] Optionally, each of the fan blades is arc-shaped.

[0021] By adopting the above technical solution, the stability of the rotating roller can be improved.

[0022] Optionally, the swing assembly further includes a connecting cover, the connecting pipe being connected to the connecting cover, and the connecting cover being detachably connected to the air supply duct.

[0023] By adopting the above technical solution, the connecting cover, connecting pipe and air supply duct can be detachably connected, which facilitates assembly and disassembly.

[0024] Optionally, the housing is provided with a sound-absorbing component for reducing noise.

[0025] By adopting the above technical solution, the sound-absorbing component can reduce the noise generated by airflow and slight structural operation within the device, thereby achieving the purpose of noise reduction.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application includes a fixed plate, a rotating roller, a transmission mechanism, a drive rod, and a connecting pipe. Two fixed plates are installed on either side of the air supply duct. The two ends of the rotating roller are rotatably connected to the two fixed plates. Multiple fan blades are mounted on the rotating roller. An opening is provided in the air supply duct, allowing the fan blades to extend into the duct. One end of the connecting pipe is connected to the air supply duct; the connecting pipe is flexible. The drive rod is rotatably connected to the fixed plate, with one end connected to the transmission mechanism and the other end rotatably connected to the connecting pipe. When the air conditioner is turned on, airflow enters the connecting pipe through the air supply duct, then delivers cool air into the space. The airflow blows the fan blades, causing the rotating roller to rotate. The rotating roller, through the transmission mechanism, drives the drive rod to rotate. Under the action of the drive rod, the end of the connecting pipe furthest from the air supply duct can oscillate. Thus, through the cooperation of the rotating roller, transmission mechanism, and drive rod, the direction of airflow can be changed, resulting in a wider airflow angle and better airflow effect. Furthermore, this application directly utilizes airflow as the driving source, significantly reducing costs. 2. The transmission mechanism in this application includes a driving gear and a driven gear. The driving gear is fixedly connected to the end of the rotating roller, and the driven gear is rotatably connected to the fixed plate. The driving gear and the driven gear mesh, and a protrusion is formed on the driven gear. A limiting groove for the protrusion to be inserted is provided on the drive rod. The limiting groove is set along the length direction of the drive rod, and the protrusion can slide in the limiting groove. In this way, the rotating roller drives the driving gear to rotate, and the driving gear in turn drives the driven gear to rotate. The protrusion and the driven gear together form a cam mechanism. Through the mutual cooperation of the protrusion, the driven gear and the limiting groove, the end of the connecting pipe away from the air supply pipe can achieve reciprocating oscillation, which is more practical. 3. This application also includes an auxiliary guide groove and an auxiliary gear. The auxiliary gear is rotatably connected to the connecting pipe. The auxiliary guide groove is arc-shaped and has multiple protruding teeth machined inside, each of which can mesh with the auxiliary gear. In this way, during the reciprocating oscillation of the connecting pipe, the auxiliary gear is driven to oscillate together. Through the cooperation of the auxiliary gear and the auxiliary guide groove, the stability of the connecting pipe during oscillation can be improved, thereby achieving more stable air delivery.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an air conditioning vent direction adjustment device, which is installed at the air outlet of the air supply duct 1, referring to... Figure 1 and Figure 2 The air conditioning vent air direction adjustment device includes a fixed plate 2, a rotating roller 3, a drive device 4, and a swing assembly 5. The swing assembly 5 includes a connecting pipe 51. There are two fixed plates 2, which are respectively installed on both sides of the air supply duct 1 and are arranged in parallel opposite directions. The two ends of the rotating roller 3 are rotatably connected to the two fixed plates 2 respectively. The rotating roller 3 is provided with a fan blade 6, which is arranged along the length of the rotating roller 3. An opening 7 is opened on the air supply duct 1 for the fan blade 6 to extend into the air supply duct 1. One end of the connecting pipe 51 is connected to the air supply duct 1. The drive device 4 is arranged between the connecting pipe 51 and the rotating roller 3. The rotating roller 3 can drive the end of the connecting pipe 51 away from the air supply duct 1 to swing through the drive device 4.

[0031] In use, the central air conditioning is turned on, and the generated cold air enters the air supply duct 1. At the same time, when the fan blades 6 enter the air supply duct 1 through the opening 7, the cold air can drive the rotating roller 3 to rotate by blowing the fan blades 6. Under the transmission action of the drive device 4, the rotating roller 3 can indirectly drive the end of the connecting pipe 51 away from the air supply duct 1 to swing. In this way, through the cooperation of the rotating roller 3 and the drive device 4, the continuous automatic change of the air supply direction is realized, thereby achieving a wider air supply angle and a better air supply effect.

[0032] Specifically, refer to Figure 1 and Figure 2The driving device 4 includes a driving rod 41 and a transmission mechanism 42. The driving rod 41 is rotatably connected to the fixed plate 2 via a rotating shaft 8. One end of the driving rod 41 is rotatably connected to the connecting pipe 51, and the other end of the driving rod 41 is connected to the transmission mechanism 42. The transmission mechanism 42 realizes the transmission of force between the rotating roller 3 and the driving rod 41. In this way, when the rotating roller 3 rotates, the transmission mechanism 42 can drive the driving rod 41 to rotate around the rotating shaft 8, thereby realizing the swing of the end of the connecting pipe 51.

[0033] Reference Figure 1 and Figure 2 The transmission structure includes a driving gear 421 and a driven gear 422. The driving gear 421 is fixedly connected to the rotating roller 3, and the driven gear 422 is rotatably connected to the fixed plate 2. The driving gear 421 and the driven gear 422 mesh. A cylindrical protrusion 423 is formed on the driven gear 422. A limiting groove 411 for the protrusion 423 to be inserted is provided on the drive rod 41. The limiting groove 411 is set along the length direction of the drive rod 41, and the protrusion 423 can slide in the limiting groove 411. The protrusion 423 and the driven gear 422 together form a cam mechanism. The rotating roller 3 drives the driving gear 421 to rotate, and the driving gear 421 in turn drives the driven gear 422 to rotate. Through the mutual cooperation of the protrusion 423, the driven gear 422 and the limiting groove 411, the end of the connecting pipe 51 away from the air supply pipe 1 can realize continuous reciprocating oscillation, which improves the air supply effect.

[0034] In this embodiment, the transmission mechanism 42 uses gear transmission, that is, the driving gear 421 and the driven gear 422 mesh. Of course, the transmission mechanism 42 can also use belt transmission, chain transmission, etc. In this embodiment, gear transmission is preferred, as this type of transmission has a more compact structure and higher stability.

[0035] Reference Figure 1 and Figure 2 There are two transmission mechanisms 42 and two drive rods 41. The two drive rods 41 are located on both sides of the connecting pipe 51. The drive rods 41 and the transmission mechanism 42 are arranged in a one-to-one correspondence. That is, when the roller 3 rotates, it can drive the two driving gears 421 to rotate, which in turn drives the two driven gears 422 to rotate synchronously. During the swinging process of the connecting pipe 51, it can ensure that the force on both sides of the connecting pipe 51 is uniform, thereby improving the stability of the connecting pipe 51 during swinging.

[0036] Of course, depending on the actual situation, a single-side drive method can also be adopted, that is, only one side is set with a driving gear 421 and two driven gears 422 are connected by a connecting shaft. In this way, one driving gear 421 can drive two driven gears 422 to rotate.

[0037] It should be noted that, referring to Figure 1 and Figure 2The diameter of the driven gear 422 is much larger than that of the driving gear 421, and the protrusion 423 is positioned close to the edge of the driven gear 422. This ensures that the rotational speed of the driven gear 422 is much lower than that of the driving gear 421, facilitating control of the oscillation speed of the connecting pipe 51 and further guaranteeing stability. Because the protrusion 423 is positioned close to the edge of the driven gear 422, its rotation radius is maximized, ensuring the maximum oscillation angle of the connecting pipe 51 and improving the air delivery effect.

[0038] Of course, there are multiple fan blades 6, which are evenly spaced along the circumference of the rotating roller 3. This ensures the stability of the oscillation frequency of the connecting pipe 51 and the continuous rotation of the rotating roller 3. Each fan blade 6 is arc-shaped. Since the airflow in the air supply duct 1 is relatively strong, the arc-shaped structure can improve the uniformity and stability of the force on the fan blades 6, thereby ensuring the stability of the rotating roller 3 during rotation and laying the foundation for subsequent transmission.

[0039] It is understood that the connecting pipe 51 is a flexible hose. In this embodiment, the material of the connecting pipe 51 is not specifically limited, as long as it can accommodate the swinging motion of the connecting pipe 51. Further, referring to... Figure 1 and Figure 2 The swing assembly 5 also includes a connecting cover 52, on which the connecting pipe 51 is connected. The connecting cover 52 is detachably connected to the air supply duct 1. The connecting cover 52 enables a detachable connection between the connecting pipe 51 and the air supply duct 1, facilitating assembly and disassembly. Of course, the detachable connection can be achieved using bolts, self-tapping screws, snap-fit ​​connections, etc. In this embodiment, the method of detachable connection is not limited.

[0040] Reference Figure 1 and Figure 2 The oscillating assembly 5 also includes a connecting frame 53, which is connected to the end of the connecting pipe 51 away from the air supply duct 1. The drive rod 41 is rotatably connected to the connecting frame 53. This serves two purposes: firstly, it protects the connecting pipe 51 from damage due to excessive wind force; secondly, it facilitates the installation and connection of the drive rod 41. Alternatively, a dustproof mesh can be installed inside the connecting frame 53 to reduce the possibility of foreign objects or dust entering the connecting pipe 51.

[0041] Reference Figure 1 and Figure 3The air conditioning vent adjustment device also includes a housing 9, which is fitted onto the air supply duct 1 and the connecting pipe 51. A fan-shaped vent 10 is formed at the end of the housing 9 furthest from the air supply duct 1, ensuring the normal oscillation of the connecting pipe 51. The housing 9 protects the air supply duct 1, the connecting pipe 51, and the transmission mechanism 42, and also encloses the air supply duct 1 and the connecting pipe 51, reducing noise during operation.

[0042] Reference Figure 3 The connecting pipe 51 is also equipped with a stabilizing component 11, which can improve the stability of the connecting pipe 51 during the swinging process.

[0043] Specifically, refer to Figure 2 and Figure 4 The stabilizing component 11 includes an auxiliary gear 111, which is rotatably connected to the drive rod 41. The auxiliary gear 111 is installed at the end of the drive rod 41 away from the driven gear 422. In this embodiment, two auxiliary gears 111 are provided, one on each of the two drive rods 41. An auxiliary guide groove 112 is provided on the housing 9. The auxiliary guide groove 112 is arc-shaped, and its shape can match the swing angle of the connecting pipe 51. Multiple protruding teeth 113 are machined in the auxiliary guide groove 112, and each protruding tooth 113 can mesh with the auxiliary gear 111. Through the cooperation of the auxiliary gear 111 and the auxiliary guide groove 112, the auxiliary gear 111 can play a supporting role during the swing of the connecting pipe 51, which can improve the stability of the connecting pipe 51 during the swing process and achieve more stable air supply.

[0044] Of course, an arc-shaped auxiliary guide can also be machined on the inner wall of the housing 9, and then multiple protruding teeth 113 can be machined on the auxiliary guide. The meshing action of the auxiliary gear 111 and the protruding teeth 113 can be used to achieve a stabilizing effect. In this embodiment, only the auxiliary guide groove 112 is used as an example for explanation.

[0045] The housing 9 is also equipped with a sound-absorbing component (not shown in the figure) for noise reduction. The sound-absorbing component can be made of sound-absorbing cotton, sound-absorbing board, etc. The sound-absorbing component can reduce the noise generated by airflow and slight structural operation in the device, thereby achieving the purpose of further noise reduction.

[0046] It should be noted that, in this embodiment, the connection methods not described may be detachable or fixed, and will not be described in detail in this embodiment.

[0047] The implementation principle of the air conditioning vent air direction adjustment device in this embodiment is as follows: After the central air conditioning is started, the generated cold air enters the connecting pipe 51 through the air supply duct 1 and is sent into the required space through the vent 10. During the flow of cold air, the cold air comes into contact with the fan blades 6, thereby driving the rotating roller 3 to rotate. The rotating roller 3 drives the driving gear 421 to rotate, and the driving gear 421 in turn drives the driven gear 422 to rotate. Through the cooperation of the drive rod 41, the protrusion 423 and the limiting groove 411, the drive rod 41 can rotate around the rotating shaft 8, which can drive one end of the connecting pipe 51 to swing. At the same time, through the cooperation of the auxiliary gear 111 and the auxiliary guide groove 112, the stability of the swing can be improved. In this way, the continuous automatic change of the air supply direction is realized, thereby achieving a wider air supply angle and a better air supply effect. At the same time, the cold air generated by the central air conditioning itself is directly used as the driving source, eliminating the need for additional driving equipment and greatly reducing costs.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
