Description

Technical Field

[0001] This utility model belongs to the technical field of air handling equipment, specifically relating to a louvered flipping device and a fresh air unit. Background Technology

[0002] Traditional multi-louver overlapping designs open or close the air outlet by stacking the louvers together. However, these designs have poor sealing reliability, and the overlapping of multiple louvers may not be consistent or may not be properly aligned, leading to air leakage. Therefore, some designs on the market use integrated louver opening and closing mechanisms. Since integrated louver opening and closing designs require completely blocking the air outlet, a pushing mechanism is needed to rotate the louvers.

[0003] Traditional louver mechanisms mostly use a wax motor to directly drive the louvers. Since the louvers move in a circular motion, the conversion rate from linear to circular motion is not high, and a relatively long driving distance is required for the louvers to open to meet the air duct conditions.

[0004] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Utility Model Content

[0005] One of the objectives of this utility model is to provide a louver flipping device that addresses the shortcomings of existing technology by using a combination of a slanted groove and a rocker arm to open the louvers to a state that meets the air duct conditions with only a short push distance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A louvered tilting device includes a housing and a telescopic assembly installed inside the housing. The telescopic end of the telescopic assembly is connected to a pusher. The pusher has a groove on its side. The side of the housing has an air outlet. A blade is provided at the air outlet. The blade and the housing are rotatably connected. One end of the blade is connected to a rocker arm. One end of the rocker arm extends into the groove.

[0008] Preferably, a mounting bracket is provided inside the housing, and the telescopic component is mounted on the mounting bracket.

[0009] Preferably, a limiting member is provided inside the housing, and a limiting piece is provided on the side of the limiting member, with the side of the limiting piece corresponding to one side of the pushing member.

[0010] Preferably, a mounting plate is provided on one side of the housing, and a panel is provided on the mounting plate.

[0011] The second objective of this utility model is to provide a fresh air unit, including the louvered rotating device as described above, with a pipe connected to one side of the housing, and the pipe connected to the air outlet.

[0012] Preferably, one end of the pipe is provided with a rain cover, and the surface of the rain cover has at least one air inlet.

[0013] Preferably, a filter element is provided inside the pipe, and a first support is provided between the filter element and the pipe.

[0014] Preferably, a filter screen is also provided inside the pipe, and a second support is provided between the filter screen and the pipe. The end of the second support and the end of the first support are respectively provided with a buckle and a retaining ring, and the buckle and the retaining ring are engaged with each other.

[0015] Preferably, a limiting step is provided at the end of the first bracket, and one end of the second bracket abuts against the limiting step.

[0016] Preferably, a fan is also installed inside the pipe, with one end of the fan abutting against one end of the second support.

[0017] Preferably, a positioning element is provided inside the second bracket, and a buffer pad is provided between the positioning element and the filter screen.

[0018] The beneficial effects of this utility model are as follows: This utility model includes a housing and a telescopic assembly installed inside the housing. The telescopic end of the telescopic assembly is connected to a pusher. The telescopic assembly can be a wax motor, a telescopic motor, or other actuator capable of generating controllable linear telescopic motion. The telescopic end refers to the end of the telescopic assembly capable of linear telescopic motion. The side of the pusher has an inclined groove, which forms an inclination angle with the side of the pusher near the housing. The side of the housing has an air outlet, and a blade is provided at the air outlet. The blade and the housing are rotatably connected. One end of the blade is connected to a rocker arm, and one end of the rocker arm is provided with a limit body. One end of the rocker arm extends into the inclined groove. The telescopic end of the telescopic assembly pushes the pusher arm to move. The inclined groove will generate an upward thrust on the end of the rocker arm that extends into the inclined groove, so that the end of the rocker arm connected to the blade can push the blade to perform a circular opening motion. This setting improves the conversion rate of linear to circular motion when the blade opens, so that the telescopic assembly only needs to push a very short distance to open the louvers to the state that meets the air duct conditions.

[0032] The following is in conjunction with the appendix Figures 1-8 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.

[0033] Example 1

[0034] A louvered flipping device, such as Figures 1-3As shown, the device includes a housing 1 and a telescopic assembly 2 installed inside the housing 1. The telescopic end of the telescopic assembly 2 is connected to a pusher 3. The telescopic assembly 2 can be a wax motor, a telescopic motor, or other actuator capable of generating controllable linear telescopic motion. The telescopic end refers to the end of the telescopic assembly 2 capable of linear telescopic motion. The pusher 3 has a groove 31 on its side, forming an angle θ with the side of the pusher 3 near the housing 1. The angle θ is acute and is opposite to the telescopic end of the telescopic assembly 2. The angle θ can be selected according to specific circumstances; for example, it can be 30~70 degrees. The housing 1 has an air outlet 11 on its side, with a blade 4 at the air outlet 11. The blade 4 is rotatably connected to the housing 1. One end of the blade 4 is connected to a rocker arm 5, with a limiter 51 at one end. One end of the rocker arm 5 is rotatably connected to the housing 1 and connected to the blade 4. The other end of the rocker arm 5 extends into the groove 31. One end of the blade 4 has a connecting protrusion for air outlet... One side wall of the outlet 11 has a first connecting hole, and one end of the connecting protrusion extends into the first connecting hole, allowing the blade 4 to rotate on the housing 1. The other side wall of the outlet 11 has a second connecting hole. The rocker arm 5 includes a rod body, a first protrusion, and a second protrusion. The first protrusion is located on one side wall of one end of the rod body, and the second protrusion is located on the other side wall of the other end of the rod body. One end of the first protrusion passes through the second connecting hole and connects to the other end of the blade 4. One end of the second protrusion extends into the inclined groove 31. The telescopic end of the telescopic component 2 pushes the pusher 3 to move. The inclined groove 31 will generate an upward thrust relative to the side of the pusher 3 closer to the housing 1 on the end of the rocker arm 5 that extends into the inclined groove 31, so that the end of the rocker arm 5 connected to the blade 4 can push the blade 4 to perform a circular opening motion. This setting improves the conversion rate of the blade 4 from linear to circular motion when it opens, so that the telescopic component 2 only needs to push a very short distance to open the blade 4 to the state that meets the air duct conditions. The structural design of a single blade 4 simplifies the airflow path, reduces turbulence and vortices caused by the collision and separation of airflow with the edges of multiple blades 4, and reduces the aerodynamic noise of turbulence in the fan 65 system.

[0035] Preferably, the telescopic component 2 is a wax motor. When the blade 4 needs to close, the wax motor telescopic rod automatically retracts after power is cut off. The linear retraction force of the wax motor pulls the pusher 3 back to its original position. The inclined groove 31 generates a downward oblique force on the end of the rocker arm 5 that extends into the inclined groove 31, relative to the side of the pusher 3 closest to the housing 1. This allows the end of the rocker arm 5 connected to the blade 4 to pull the blade 4 to perform a circular closing motion, thus closing the blade 4. The telescopic rod of the wax motor maintains a fixed retraction force, thereby firmly tightening the blade 4 and forming a closed self-locking structure. This retraction force is a structural characteristic of the wax motor. The wax motor described here is a conventional wax motor and will not be described in detail here.

[0036] In this embodiment, a mounting bracket 12 is provided inside the housing 1, and the telescopic component 2 is mounted on the mounting bracket 12. By providing the mounting bracket 12, the main body of the telescopic component 2 can be prevented from shifting when the telescopic end of the telescopic component 2 pushes the pusher 3.

[0037] In this embodiment, a limiting member 13 is provided inside the housing 1, and a limiting piece 131 is provided on the side of the limiting member 13. The side of the limiting piece 131 is correspondingly provided with one side of the pushing member 3. The side wall of the limiting member 13 and the side of the limiting piece 131 near the pushing member 3 work together to restrict the pushing member 3 to one side of the housing 1, so that the pushing member 3 can maintain linear movement.

[0038] Preferably, the housing 1 is provided with a U-shaped groove 17 and an airflow channel 18. The U-shaped groove 17 is located outside the airflow channel 18 and an airflow baffle 19 is provided between it and the airflow channel 18. The air outlet 11 is connected to the airflow channel 18. The telescopic component 2, the pusher 3, the mounting bracket 12, the limiting component 13, and the rod and second protrusion of the rocker 5 are all located in the U-shaped groove 17. This arrangement can play an isolation role, avoiding the telescopic component 2, the pusher 3, the mounting bracket 12, the limiting component 13, and the rod and second protrusion of the rocker 5 from affecting the airflow, thereby improving the accuracy of airflow control.

[0039] Preferably, the blades 4 cover the air outlet 11 and are flush with the end face of the air outlet 11. In traditional solutions, the integrated louver design requires completely blocking the air outlet 11, resulting in relatively large louver sizes. This leads to a larger space required to open the air outlet, and due to limitations in the louver-pushing mechanism, a large space needs to be reserved at the air outlet 11 to ensure the opening and closing of the louvers and the operation of the louver-pushing structure, resulting in a relatively large overall size of the main unit. This invention adopts a design where the integrated louver is flush with the end face of the air outlet 11 of the housing 1. While ensuring sufficient space, it optimizes the design of the louver-pushing mechanism, reduces the size of the main unit, and lowers the space it occupies indoors.

[0040] Example 2

[0041] The difference between this embodiment and embodiment 1 is that, Figure 4As shown, a mounting plate 14 is provided on one side of the housing 1, and a panel 15 is provided on the side of the mounting plate 14 away from the housing 1. The panel 15 covers the housing 1, preventing the airflow inside the housing 1 from flowing out from the side of the panel 15. A PCB circuit board 8 and a button module 9 are provided inside the housing 1. The PCB circuit board 8 is electrically connected to the telescopic component 2 and the button module 9. A control chip is provided on the PCB circuit board 8, and the control chip is electrically connected to both the button module 9 and the telescopic component 2. The control chip can be a microcontroller chip or an ARM chip. When the user operates the button module 9, they can send commands to the control chip. After processing the commands, the control chip controls the telescopic component 2 to open and close the blades 4. The control chip is also electrically connected to a wireless communication module, which is also provided on the PCB circuit board 8. The user can send commands to the control chip via a remote control. A fixing bracket 16 is provided on the side of the mounting plate 14 facing the inside of the housing 1, and one end of the fixing bracket 16 abuts against one end of the mounting bracket 12. By setting the fixed bracket 16, the mounting bracket 12 can be pressed down, so that the telescopic component 2 fits more closely with the mounting bracket 12, and the telescopic component 2 is prevented from shaking on the mounting bracket 12.

[0042] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0043] Example 3

[0044] A fresh air unit includes a louvered tilting device as described in Embodiment 1 or Embodiment 2. A duct 6 is connected to one side of the housing 1, and the duct 6 is connected to an air outlet 11. The duct 6 facilitates communication between the housing 1 and the outside.

[0045] In this embodiment, as Figure 5 As shown, a rain cover 7 is provided at one end of the pipe 6. The surface of the rain cover 7 has at least one air inlet 71, which is connected to the pipe 6. Multiple downward-sloping louvers are provided at the air inlet 71 to prevent water from falling into the rain cover 7.

[0046] In this embodiment, as shown... Figures 6-8 As shown, a filter element 61 is installed inside the pipe 6, and a first support 62 is installed between the filter element 61 and the pipe 6, with the filter element 61 housed inside the first support 62. The first support 62 is a cylindrical structure, and an abutment ring is provided on the outer periphery of one end of the first support 62. During installation, the side wall of the abutment ring will abut against one end of the pipe 6, which can prevent the first support 62 from falling completely into the pipe 6 and facilitate the replacement of the filter element 61 later.

[0047] In this embodiment, a filter screen 63 is also provided inside the pipe 6. A second support 64 is provided between the filter screen 63 and the pipe 6. The filter screen 63 is disposed inside the second support 64. Multiple buckles 641 are provided at the end of the second support 64, and multiple retaining rings 621 are provided at the end of the first support 62. The buckles 641 and retaining rings 621 are interlocked. The second support 64 is also a cylindrical structure. The first support 62 and the second support 64 can be connected by the interlocking of the buckles 641 and retaining rings 621, which facilitates the replacement of the filter screen 63 later.

[0048] In this embodiment, a limiting step 622 is provided on the inner side of the end of the first bracket 62, and one end of the second bracket 64 abuts against the limiting step 622. By providing the limiting step 622, one end of the second bracket 64 can be prevented from excessively extending into the first bracket 62.

[0049] In this embodiment, as Figures 5-6 As shown, a fan 65 is also installed inside the pipe 6. The fan 65 is electrically connected to the PCB circuit board 8. One end of the fan 65 abuts against one end of the second bracket 64. The air outlet 11 is located on the top of the housing 1. The opening of the air outlet 11 is set upward. After the noise generated by the fan 65 is discharged upward with the airflow, it first hits the ceiling. The ceiling acts as an acoustic barrier, absorbing and scattering most of the sound energy, significantly changing the main propagation path of the noise. In addition, the upward design of the air outlet can ensure the amount of fresh air exchange in the room while avoiding cold air blowing directly on the user, thus optimizing the user experience.

[0050] In this embodiment, a positioning element 642 is provided inside the second support 64, and a buffer pad 643 is provided between the positioning element 642 and the filter screen 63. By providing the buffer pad 643, direct contact between the filter screen 63 and the positioning element 642 can be avoided, thus preventing damage to the mesh structure of the filter screen 63 and affecting the filtration effect.

[0051] Obviously, this utility model includes a housing and a telescopic assembly installed inside the housing. The telescopic end of the telescopic assembly is connected to a pusher. The telescopic assembly can be a wax motor, a telescopic motor, or other actuator capable of generating controllable linear telescopic motion. The telescopic end refers to the end of the telescopic assembly capable of linear telescopic motion. The side of the pusher has an inclined groove, which forms an inclination angle with the side of the pusher near the housing. The side of the housing has an air outlet, and a blade is provided at the air outlet. The blade is rotatably connected to the housing. One end of the blade is connected to a rocker arm, and one end of the rocker arm is provided with a limit body. One end of the rocker arm extends into the inclined groove. The telescopic end of the telescopic assembly pushes the pusher arm to move. The inclined groove will generate an upward thrust on the end of the rocker arm that extends into the inclined groove, so that the end of the rocker arm connected to the blade can push the blade to perform a circular opening motion. This setting improves the conversion rate of linear to circular motion when the blade opens, so that the telescopic assembly only needs to push a short distance to open the louvers to the state that meets the air duct conditions.

Therefore, the utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the utility model are within the protection scope of the utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
