Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air-supplying air conditioner with automatically adjustable wind speed. Background Technology

[0002] In scenarios such as indoor environmental control in buildings and ventilation in industrial plants, air supply air conditioners are key equipment for ensuring air circulation and comfort. Different usage scenarios have significantly different requirements for airflow speed. For example, conference rooms require gentle airflow to avoid direct airflow, while large workshops require strong airflow to achieve rapid air replacement. Therefore, air supply air conditioners with flexible and stable airflow adjustment functions are crucial for improving user experience and environmental quality.

[0003] Most existing air-conditioning systems use manual fan speed adjustment, controlled by knobs or switches. This method is not only cumbersome but also makes precise fan speed control difficult. Over long-term use, the mechanical structure is prone to loosening or wear, leading to unstable fan speed adjustment and inconsistent airflow. Furthermore, some air conditioners with automatic fan speed adjustment mechanisms lack a buffer design. When encountering changes in resistance (such as obstructions in the air duct), they are prone to jamming or adjustment failure, affecting the normal operation of the air conditioner.

[0004] Therefore, a wind-supply air conditioner with automatically adjustable wind speed is proposed to address the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of an air-supply air conditioner with automatically adjustable wind speed, including a base plate 1 as the basic support component of the entire air-supply air conditioner, providing a stable installation platform for structures such as the housing 2, ensuring the stability of the air conditioner during operation. At the same time, the cavities 17 on the left and right sides inside provide installation and movement space for components such as the locking plate 20. The top of the base plate 1 is provided with the housing 2, which forms the main space of the air-supply air conditioner and accommodates the internal components. Multiple air outlets 3 opened on the rear side are channels for airflow, and at the same time provide installation positions for structures such as the fixing plate 1 4 and the fixing plate 3 14, ensuring a reasonable internal structural layout of the air conditioner. Multiple air outlets 3 are opened on the rear side of the housing 2, which are the outlets for the air conditioner to deliver regulated airflow to the outside. The size of their area affects the airflow speed and volume. The effective ventilation area can be adjusted by the wind baffle 13.

[0033] A fixing plate 4 is fixedly connected to the top left side of the housing 2. This plate is used to install the motor 5 in the drive assembly, providing a stable mounting base for the motor 5 and ensuring its stable operation, thus guaranteeing the reliable operation of the drive assembly. The top of the fixing plate 4 houses the drive assembly, which provides power to the device. This drive assembly consists of the motor 5, a threaded rod 6, and a fixing plate 7, providing power for the device to adjust the wind speed. The motor 5 drives the threaded rod 6 to rotate, and through its threaded connection with the housing 8, it moves the housing 8, thereby driving related components to adjust the wind speed. The drive assembly is externally threaded, with the housing 8 and threaded rod 6 connected, moving axially under the drive of the threaded rod 6. Internally, it is used to install components such as the fixing rod 9, spring 10, and limiting plate 11, simultaneously driving these components to move synchronously, thereby adjusting the area of ​​the air outlet 3. The drive assembly, including the motor 5 mounted on the top of the fixing plate 4, serves as the power source for the drive assembly, converting electrical energy into mechanical energy and outputting power to drive the threaded rod 6 to rotate. It is the core power component for achieving automatic wind speed adjustment.

[0034] The top of the threaded rod 6 is fixedly connected to the output end of the motor 5, and the bottom is rotatably connected to the top of the second fixing plate 7. Through its own rotation, and by utilizing the threaded engagement with the housing 8, it converts the rotational motion of the motor 5 into the linear motion of the housing 8. It is a key transmission component driving the movement of the housing 8. The second fixing plate 7 is fixed to the bottom left side of the housing 2 to support the bottom of the threaded rod 6, ensuring the stability and coaxiality of the threaded rod 6 during rotation, so that the threaded rod 6 can reliably transmit the power of the motor 5 to the housing 8. The bottom of the motor 5 is set on the top of the first fixing plate 4, and the threaded rod 6... The top of the housing 8 is fixedly connected to the output end of the motor 5. The bottom left side of the housing 8 is threadedly connected to the outside of the threaded rod 6. The bottom of the threaded rod 6 is rotatably connected to the top of the fixing plate 7. The outside of the fixing plate 7 is fixedly connected to the bottom left side of the housing 2. Two fixing rods 9 are fixedly connected to the left and right sides of the inside of the housing 8. They provide guidance for the sliding of the limiting plate 11, ensuring that the limiting plate 11 can only slide along the axial direction of the fixing rods 9. At the same time, they provide support for the spring 10, so that the spring 10 can play an elastic buffering role.

[0035] A spring 10 is fitted around the outside of the fixing rod 9, with one end fixed to the inner wall of the housing 8 and the other end fixed to the outside of the limiting plate 11. When the housing 8 moves the limiting plate 11 and encounters changes in resistance, the spring 10 buffers the movement through elastic deformation. This, combined with the sliding of the limiting plate 11, ensures that the baffle plate 13 always maintains good contact with the air outlet 3. Multiple fixing rods 9 are slidably connected to the limiting plate 11, which is slidably connected inside the housing 8 and fitted around the outside of the fixing rods 9, for connecting the connecting plate 12. When the housing 8 moves, the limiting plate 11 slides along the fixed rod 9 and, under the action of the spring 10, limits and buffers the connecting plate 12 and the baffle plate 13, ensuring the stability of the baffle plate 13 adjustment. One end of the spring 10 is fixedly connected to the inner wall of the housing 8, and the other end of the spring 10 is fixedly connected to the outside of the limiting plate 11. The outside of the limiting plate 11 is slidably connected to the inside of the housing 8. The outside of the limiting plate 11 is fixedly connected to the connecting plate 12, which is used to connect the limiting plate 11 and the baffle plate 13, and transmit the movement of the limiting plate 11 to the baffle plate 13, so that the baffle plate 13 can move synchronously with the limiting plate 11, thereby realizing the adjustment of the area of ​​the air outlet 3.

[0036] A baffle plate 13 is fixedly connected to the outside of the connecting plate 12 and contacts the outside of the air outlet 3. By moving it, the area of ​​the air outlet 3 is changed, thereby adjusting the airflow speed of the air conditioner. Driven by the housing 8, the ventilation area of ​​the air outlet 3 can be precisely controlled to achieve stable wind speed adjustment. The outside of the baffle plate 13 contacts the outside of the air outlet 3. A fixing plate 3 14 is fixedly connected to the top right side of the housing 2 and is used to install the fixing rod 2 15, providing stable support for the fixing rod 2 15 and ensuring that the guiding effect of the fixing rod 2 15 on the housing 8 is stable and reliable. The bottom of the fixing plate 3 14 is fixedly connected to the top of the fixing rod 2 15 and the bottom is fixedly connected to the fixing plate 4 16. Its outside is slidably connected to the bottom right side of the housing 8, which guides the movement of the housing 8 and ensures that the housing 8 remains stable and does not deviate during the movement.

[0037] The bottom right side of the housing 8 is slidably connected to the outside of the fixing rod 2 15. The bottom of the fixing rod 2 15 is fixedly connected to the fixing plate 4 16, which is fixed to the bottom right side of the housing 2. This is used to fix the bottom of the fixing rod 2 15, further enhancing the stability of the fixing rod 2 15 and ensuring that the fixing rod 2 15 can reliably guide the housing 8. The outside of the fixing plate 4 16 is fixedly connected to the bottom right side of the housing 2.

[0038] Reference Figure 1 and Figure 4 The base plate 1 has cavities 17 on both the left and right sides inside, providing installation space for components such as guide rods 18, springs 19, and locking plates 20. It also provides space for the insertion plate 21 to be inserted into the base plate 1, enabling the housing 2 and the base plate 1 to be quickly installed and fixed. Guide rods 18 are fixedly connected inside the two cavities 17, providing guidance for the sliding of the locking plate 20. This ensures that the locking plate 20 can only slide along the axial direction of the guide rods 18, ensuring that the locking plate 20 is accurately positioned when engaging or disengaging from the locking hole 22 of the insertion plate 21. Springs 19 are sleeved on the outside of the two guide rods 18, with one end fixed to the inner wall of the cavity 17 and the other end fixed to the outside of the locking plate 20. When the housing 2 is installed, the second spring 19 is compressed by the locking plate 20. When the locking hole 22 of the insertion plate 21 corresponds to the locking plate 20, the second spring 19 resets and pushes the locking plate 20 into the locking hole 22. When disassembling, the locking plate 20 is pressed to compress the second spring 19, so that the locking plate 20 is disengaged from the locking hole 22, which plays the role of elastic reset and buffer.

[0039] A locking plate 20 is slidably connected to the outside of the guide rod 18 and the inside of the cavity 17. It cooperates with the locking hole 22 of the insertion plate 21 to achieve quick installation and fixation of the housing 2 and the base plate 1. During installation, the spring 19 is compressed by the insertion plate 21 and slides along the guide rod 18. When it corresponds to the locking hole 22, it is locked in place by the action of the spring 19. During disassembly, it is pressed out of the locking hole 22. This is a key component for achieving quick assembly and disassembly. One end of the spring 19 is fixedly connected to the inner wall of the cavity 17, and the other end is fixedly connected to the outside of the locking plate 20. The bottom of the locking plate 20 is slidably connected to the inside of the cavity 17. Insertion plates 21 are fixedly connected to the left and right sides of the bottom of the housing 2, and are inserted into the cavity 17 of the base plate 1. Inside, the bottom locking hole 22 cooperates with the locking plate 20 to achieve a fixed connection between the housing 2 and the base plate 1. At the same time, during the installation process, squeezing the locking plate 20 triggers the locking action. The bottom of the insertion plate 21 has a locking hole 22 that cooperates with the locking plate 20. When the insertion plate 21 is inserted into the cavity 17 of the base plate 1, the locking hole 22 corresponds to the locking plate 20. Under the action of the spring 19, the locking plate 20 is locked into the locking hole 22, achieving a firm connection between the housing 2 and the base plate 1. One side of the locking plate 20 is locked with the inside of the locking hole 22.

[0040] Working principle: When the device needs to be quickly installed in a specific position, the housing 2 can be placed on top of the base plate 1. At this time, the insertion plate 21 at the bottom of the housing 2 will be inserted into the corresponding position of the cavity 17 of the base plate 1. During the insertion process, the insertion plate 21 presses against the locking plate 20. The locking plate 20 slides along the guide rod 18 and compresses the second spring 19. When the locking hole 22 of the insertion plate 21 corresponds to the locking plate 20, the second spring 19 returns to its original position and pushes the locking plate 20 into the locking hole 22, realizing the quick installation and fixation of the housing 2 and the base plate 1.

[0041] Next, the drive assembly is activated to adjust the wind speed. Motor 5 in the drive assembly operates, and its output drives the threaded rod 6 to rotate. Since the housing 8 is threadedly connected to the threaded rod 6, the rotation of the threaded rod 6 causes the housing 8 to move axially along the threaded rod 6. As the housing 8 moves, its internal components, such as the fixing rod 9, spring 10, limiting plate 11, connecting plate 12, and baffle plate 13, move synchronously. The baffle plate 13 contacts the air outlet 3, and during the movement of the housing 8, the wind speed is adjusted by changing the area of ​​the air outlet 3 blocked by the baffle plate 13. Simultaneously, the bottom right side of the housing 8 slides along the fixing rod 15, which guides the housing 8 and ensures smooth movement.

[0042] When the housing 8 moves the baffle plate 13 to adjust the area of ​​the air outlet 3, if a change in resistance is encountered (such as a change in the frictional resistance between the baffle plate 13 and the edge of the air outlet 3), the spring 10 inside the housing 8 can deform elastically and slide along the fixed rod 9 in conjunction with the limiting plate 11, so that the outside of the baffle plate 13 is always in contact with the outside of the air outlet 3.

[0043] When it is necessary to adjust the installation position of the device or perform maintenance, the locking plate 20 can be pressed to compress the spring 19 and disengage it from the locking hole 22, so that the housing 2 can be removed from the base plate 1, which is convenient and quick.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
