Description

Technical Field

[0001] This application relates to the technical field of fresh air systems, and particularly to a air distribution box. Background Art

[0002] The air distribution box is an important part of the fresh air system. It is mainly responsible for evenly distributing the fresh air sent by the fresh air main unit to each room. The air distribution box can improve the environmental protection, quietness and comfort of the fresh air system.

[0003] Usually, the air distribution box is connected to each direction through pipes, and a butterfly valve is arranged between the pipe and the air distribution box. Before installing the pipe, the butterfly valve is adjusted to the corresponding angle first, and then the pipe is connected to the butterfly valve, so as to connect the air distribution box to each direction.

[0004] However, the valve plate of the butterfly valve itself is inclined, resulting in the air flow flowing out of the air distribution box also hitting the secondary air supply pipe or other pipe fittings obliquely, which will generate vibration and cause noise pollution. Utility Model Content

[0005] The purpose of this application is to provide an air distribution box that can reduce noise pollution generated during ventilation.

[0006] In a first aspect, an air distribution box provided by this application adopts the following technical solution:

[0007] An air distribution box, comprising:

[0008] An air distribution box body provided with a first interface and a second interface;

[0009] A manual iris valve, which is connected to the first interface and is used to connect the air distribution box body to a pipe;

[0010] An electric iris valve, which is connected to the second interface and is used to connect the air distribution box body to a pipe.

[0011] By adopting the above technical solution, this structural configuration enables the opening degree of the manual iris valve to be adjusted manually and the opening degree of the electric iris valve to be controlled electrically, so as to flexibly control the air supply volume of the air distribution box. By controlling the air supply volume, other environmental factors such as humidity and temperature introduced into each room can also be controlled, so as to meet diverse ventilation requirements. The manual iris valve can be connected to the living room through a pipe and supply air at a fixed air volume throughout the year, while the electric iris valve is connected to the secondary air supply pipe of the second bedroom or the guest bedroom through a pipe and is only opened during the set period, thereby reducing the system energy consumption.

[0012] Moreover, the opening sizes of the electric aperture valve and the manual aperture valve can be precisely adjusted, so that the air volume entering each secondary air supply duct can be accurately controlled. There is no problem of inclined air supply in the electric aperture valve and the manual aperture valve itself. The air flow directly enters the secondary air supply duct from the air distribution box, without lateral impact on the inner wall of the air duct, reducing vibration and thus reducing noise.

[0013] Optionally, the outer diameters of the first interface and the second interface are the same.

[0014] By adopting the above technical solution, the connected pipes can have a unified specification, which greatly facilitates the installation and maintenance process. At the same time, it also ensures that the air flow has the same flow cross-section when passing through different interfaces. This design effectively reduces energy loss and flow resistance, and improves the overall working efficiency of the air distribution box.

[0015] Optionally, a connection component is installed on the manual aperture valve, and the manual aperture valve can be connected to the pipe through the connection component;

[0016] A notch is formed on the side wall of the manual aperture valve, and the notch is communicated with the first interface. The connection component includes a clamping plate, a slideway and a fixing member. The slideway is fixedly connected to the side wall of the manual aperture valve. The clamping plate is slidably connected to the slideway and can be inserted into the notch to clamp the pipe inserted into the manual aperture valve. The fixing member is used to limit the sliding of the clamping plate.

[0017] By adopting the above technical solution, the pipe is fixed by the clamping plate, without using glue for fixation, which is convenient and fast.

[0018] Optionally, the fixing member is an elastic buckle, and the elastic buckle is fixed at one end of the clamping plate and can be clamped on the slideway.

[0019] By adopting the above technical solution, using the elastic buckle not only makes the fixing operation more simple and fast, but also its elastic characteristics can ensure that the clamping plate is not easily detached or loosened when subjected to external forces, which undoubtedly further enhances the stability and reliability of the connection.

[0020] Optionally, the connection component is also provided on the electric aperture valve.

[0021] By adopting the above technical solution, the installation flexibility is improved. At the same time, it is also convenient for separate maintenance and replacement of each component in the later stage, thereby extending the service life of the air distribution box.

[0022] Optionally, a plurality of first interfaces are provided, and each first interface is communicated with one manual aperture valve.

[0023] By adopting the above technical solution, multiple first interfaces are provided, increasing the number of rooms that the air distribution box can be connected to and adapting to houses with different house types.

[0024] Optionally, a plurality of second interfaces are provided, and each of the second interfaces is connected to one of the electric aperture valves.

[0025] By adopting the above technical solution, multiple second interfaces are provided, increasing the number of rooms that the air distribution box can be connected to and adapting to houses with different house types.

[0026] Optionally, a control switch is further included, and the control switch is electrically connected to the electric aperture valve.

[0027] By adopting the above technical solution, the electric aperture valve can be controlled by the control switch, and the control switch can be installed at different positions in the room, facilitating the user to adjust the electric aperture valve.

[0028] In a second aspect, the present application further provides a precisely controllable air distribution system, including the precisely controllable air distribution box as described above and a control component. The control component includes a detection component for detecting temperature, humidity, and air flow rate and a control component for controlling the opening size of the above electric aperture valve. The control component receives and responds to the detection signal of the detection component to control the opening size of the electric aperture valve.

[0029] Optionally, the detection component includes:

[0030] A temperature and humidity sensor, arranged in the air distribution box body and / or in the room communicated with the pipeline, for detecting and outputting the temperature and humidity values in the air distribution box body and / or in the room;

[0031] An air flow sensor, arranged in each pipeline, for detecting and outputting the air flow velocity values in each pipeline;

[0032] The control component includes a controller signal-connected to the temperature and humidity sensor and the air flow sensor, and the controller is control-connected to the electric aperture valve.

[0033] By adopting the above technical solution, the opening size of the electric aperture valve can be precisely controlled according to the indoor temperature and humidity, and then the air supply volume can be precisely controlled, which also plays a role in adjusting the indoor temperature and humidity.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. This structural configuration enables flexible control of the air supply volume of the air distribution box by manually adjusting the opening degree of the manual aperture valve and electrically controlling the opening degree of the electric aperture valve, thereby meeting diverse ventilation requirements. The manual aperture valve can be connected to the living room through a pipeline and supply air at a fixed air volume throughout the year, while the electric aperture valve is connected to the secondary air supply pipeline of the second bedroom or the guest bedroom through a pipeline and is only opened during the set period, thereby reducing the system energy consumption as well.

[0036] Moreover, the opening sizes of the electric aperture valve and the manual aperture valve can be precisely adjusted, and thus the air volume entering each secondary air supply pipeline can be accurately controlled. There is no problem of inclined air supply in the electric aperture valve and the manual aperture valve itself. The air flow enters the secondary air supply pipeline directly from the air distribution box and will not collide laterally with the inner wall of the air duct, reducing vibration and thus reducing noise.

[0037] 2. The connected pipelines can have a unified specification, which greatly facilitates the installation and maintenance processes. At the same time, it also ensures that the air flow can have the same cross-sectional area of flow when passing through different interfaces. This design effectively reduces energy loss and flow resistance and improves the overall working efficiency of the air distribution box.

[0038] 3. By controlling the electric aperture valve through a control switch, the control switch can be installed at different positions in the room, facilitating the user to adjust the electric aperture valve. Brief Description of the Drawings

Detailed Description of the Embodiment

[0044] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 4 , with further detailed description of the present application.

[0045] Embodiment 1

[0046] Referring to Figure 1 and Figure 2 , this embodiment discloses a wind distribution box, which includes a wind distribution box body 1, a manual iris valve 2 and an electric iris valve 3. A main air duct is connected to the wind distribution box body 1 for supplying air to the inner tank of the wind distribution box. The wind distribution box body 1 is specifically provided with a first interface 11 and a second interface 12. Among them, the manual iris valve 2 is connected to the first interface 11, and the electric iris valve 3 is connected to the second interface 12. This structural configuration enables flexible control of the air supply volume of the wind distribution box by manually adjusting the opening degree of the manual iris valve 2 and electrically controlling the opening degree of the electric iris valve 3, so as to meet diverse ventilation requirements. The manual iris valve 2 can be connected to the living room through a pipeline and supply air at a fixed air volume throughout the year, while the electric iris valve 3 is connected to the secondary air duct of the second bedroom or the guest bedroom through a pipeline and is only opened during the set period, thereby reducing the system energy consumption.

[0047] Moreover, the opening sizes of the electric iris valve 3 and the manual iris valve 2 can be precisely adjusted, so that the air volume entering each secondary air duct can be precisely controlled. There is no problem of inclined air supply in the electric iris valve 3 and the manual iris valve 2 itself. The air flow enters the secondary air duct straight from the wind distribution box and will not generate lateral impact on the inner wall of the air duct, reducing vibration and thus reducing noise.

[0048] Furthermore, the first interface 11 and the second interface 12 in this embodiment are designed to have the same outer diameter. This feature not only enables the connected pipelines to have a unified specification, greatly facilitating the installation and maintenance process, but also ensures that the air flow has the same flow cross-section when passing through different interfaces. This design effectively reduces energy loss and flow resistance and improves the overall working efficiency of the wind distribution box.

[0049] In this embodiment, the electric iris valve 3 is electrically connected to a control switch. Through the control switch, the opening and closing size of the electric iris valve 3 is controlled to achieve the control of the air volume transported by the pipeline. The control switch can be fixed on the wall of each room for the convenience of users.

[0050] In order to enhance the connection stability between the pipeline and the manual iris valve 2, a connection component 4 is specifically installed on the manual iris valve 2 in this embodiment. A notch 21 is opened on the side wall of the manual iris valve 2, and the notch 21 is connected to the first interface 11. The connection component 4 is composed of a clamping plate 41, a slideway 42 and a fixing member 43. The pipeline inserted into the manual iris valve 2 is clamped by inserting the clamping plate 41 into the notch 21, and then the fixing member 43 is used to restrict the sliding of the clamping plate 41, thereby realizing a stable and sealed connection between the pipeline and the manual iris valve 2. Since the pipeline uses a corrugated pipe, the clamping plate 41 is inserted into the notch 21 and can be inserted into the gap on the corrugated pipe, thereby clamping the corrugated pipe.

[0051] It is worth mentioning that the fixing member 43 in this embodiment adopts an elastic buckle, which is fixed at one end of the clamping plate 41 and can be clamped on the slideway 42. Using the elastic buckle not only makes the fixing operation more simple and rapid, but also its elastic property can ensure that the clamping plate 41 is not easily detached or loosened when subjected to external forces, which undoubtedly further enhances the stability and reliability of the connection.

[0052] In addition, this embodiment also extends the application scope of the connection component 4 to the electric aperture valve 3, enabling the electric aperture valve 3 to be equally conveniently connected to the pipeline. This design not only improves the flexibility of installation, but also facilitates the subsequent separate maintenance and replacement of each component, thereby extending the service life of the air distribution box.

[0053] To meet more complex ventilation requirements, this embodiment also provides a design scheme with multiple interfaces. Specifically, a plurality of first interfaces 11 and second interfaces 12 can be provided, and each interface can be connected to the corresponding manual aperture valve 2 or electric aperture valve 3. This design enables the operator to flexibly adjust the air supply volume of the entire air distribution box by increasing or decreasing the number of valves according to actual needs. At the same time, multiple valves can be adjusted independently of each other without interference, which provides strong support for meeting more complex and variable ventilation requirements.

[0054] The implementation principle of this embodiment is as follows: By combining manual and electric adjustment methods, the air distribution box provided in this embodiment can achieve precise control of the air supply volume. Specifically, the operator can manually adjust the opening degree of the manual aperture valve 2 according to ventilation requirements to initially adjust the air supply volume; at the same time, by electrically controlling the opening degree of the electric aperture valve 3, the air supply volume can be further precisely adjusted. This combined manual and electric adjustment method not only retains the flexibility and intuitiveness of manual adjustment, but also increases the precision and convenience of electric adjustment. In addition, by optimizing the interface design, enhancing the connection stability, and providing a design scheme with multiple interfaces and other measures, this embodiment further improves the overall performance and user experience of the air distribution box, enabling it to better meet diverse ventilation requirements.

[0055] Embodiment 2:

[0056] The structure of this Embodiment 2 is generally the same as that of Embodiment 1, and the difference lies in the improvement of the connection component 4.

[0057] Refer to Figure 3 and Figure 4, the connecting component 4 includes a driving ring 44, a locking block 45 and an elastic hook 46. There are two notches 21 opened on the side wall of the manual aperture valve 2, and the two notches 21 are symmetrically arranged about the central axis of the manual aperture valve 2. The driving ring 44 is rotatably sleeved on the manual aperture valve 2. In this embodiment, a plurality of limiting blocks are fixedly connected to the manual aperture valve 2, and the driving ring 44 is clamped in the middle by two symmetrically arranged limiting blocks to realize the limitation of the driving ring 44, so that the driving ring rotates and is sleeved on the manual aperture valve 2.

[0058] The driving ring 44 corresponds to the position of the notch 21. The locking block 45 is rotatably connected to the driving ring 44, and a torsion spring is arranged between the locking block 45 and the driving ring 44. One end of the torsion spring is fixedly connected to the locking block 45, and the other end of the torsion spring is fixedly connected to the driving ring 44. A guiding inclined surface 22 is arranged on the inner wall of the notch 21. Rotating the driving ring 44 drives the locking block 45 to slide in the notch 21. When the locking block 45 contacts the guiding inclined surface 22, the locking block 45 moves into the manual aperture valve 2 under the guiding action of the guiding inclined surface 22, so that the locking block 45 abuts against the pipeline, realizing the limitation of the pipeline. One such locking block 45 is arranged at each notch 21 position, and the pipeline is fixed by two symmetrically arranged locking blocks 45.

[0059] The elastic hook 46 is fixedly connected to the inner wall of the driving ring 44, and a bayonet 23 is opened on the outer side wall of the manual aperture valve 2. When the driving ring 44 rotates until the locking block 45 abuts against the pipeline, at this time, the elastic hook 46 is inserted into the bayonet 23 to realize the mutual fixation of the driving ring 44 and the manual aperture valve 2, so as to fix the locking block 45 and realize the fixation of the pipeline.

[0060] In addition, in this embodiment, the application range of the connecting component 4 is also extended to the electric aperture valve 3, so that the electric aperture valve 3 can also be conveniently connected to the pipeline.

[0061] The implementation principle of this embodiment 2 is as follows: First, insert the pipeline into the manual aperture valve 2, and then rotate the driving ring 44, so that the driving ring 44 drives the two locking blocks 45 to move in the notch 21 and slide into the manual aperture valve 2 under the guiding action of the guiding inclined surface 22, thereby clamping the pipeline. At this time, the elastic hook 46 is clamped into the bayonet 23 to limit the movement of the driving ring 44 and complete the fixation of the pipeline.

[0062] Based on the above-mentioned accurately controllable air distribution box, the present application also discloses an accurately controllable air distribution system, including the above-mentioned accurately controllable air distribution box and a control component. The control component includes a detection component for detecting temperature, humidity and air flow size and a control component for controlling the opening size of the above-mentioned electric aperture valve 3. The control component receives and responds to the detection signal of the detection component and controls the opening size of the electric aperture valve 3.

[0063] The above-mentioned detection components include a temperature and humidity sensor and an air flow sensor. The temperature and humidity sensor is arranged in the main body of the air distribution box 1 and / or in the room communicated with the pipeline, and is used to detect and output the temperature and humidity values in the air distribution box and / or in the room. The air flow sensor is arranged in each pipeline or at the air outlet of the pipeline, and is used to detect and output the air flow velocity values in each pipeline, so as to facilitate the subsequent calculation of the air volume.

[0064] The control component includes a controller that is signal-connected to the temperature and humidity sensor and the air flow sensor. Preferably, a PLC or a single-chip microcomputer control module is adopted. The above-mentioned controller is control-connected to the electric aperture valve 3. Relevant control data is loaded inside the controller, such as the corresponding relationship data among the temperature and humidity value, the air flow velocity value, and the opening size of the electric aperture valve 3. Thus, the opening size of the aperture valve can be directly controlled according to the current temperature and humidity value. Therefore, the opening size of the electric aperture valve 3 can be accurately controlled according to the indoor temperature and humidity, and then the air supply volume can be accurately controlled, which also plays a role in adjusting the indoor temperature and humidity.

The same parts are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
