[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In modern buildings and industrial facilities, ventilation appliances play an important role. Ventilation appliances can provide fresh air to indoor spaces, maintain indoor temperature balance, and exhaust indoor polluted gases or harmful gases, such as oil smoke. However, with the widespread use of ventilation appliances, their safety issues have become increasingly prominent, especially in the event of a fire. As one of the main channels for fire to spread, high temperatures and flames can spread quickly through ventilation ducts.

[0029] However, the valves in the existing ventilation passages cannot respond to the fire in time and cannot block the fire from spreading through the ventilation passages in time.

[0030] In view of the above problems, the present application provides a valve control system and a ventilation electrical system. The specific structures of the valve control system and the ventilation electrical system are described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Figure 1 The figure is a schematic diagram of a structure applicable to an application scenario of a valve control system provided by an embodiment of the present application. Figure 2 Shown is a schematic diagram of the working process of a valve control system provided in one embodiment of the present application. Figure 3 Shown is a schematic structural diagram of a valve control system provided in one embodiment of the present application. Figure 4Shown is a schematic structural diagram of a valve control system provided in one embodiment of the present application. Figure 5 Shown is a schematic structural diagram of a valve and an environmental detection sensor provided in one embodiment of the present application.

[0032] like Figures 1 to 5 As shown, the valve control system 1 includes: a power connection module 10 , a control module 20 , a valve 30 , at least one environment detection sensor 40 and a drive module 50 .

[0033] The power connection module 10 is configured to connect to a power source to provide power to the valve control system 1 .

[0034] The control module 20 is electrically connected to the power connection module 10 .

[0035] The valve 30 is disposed in the ventilation passage and is configured to close or open the ventilation passage.

[0036] The environment detection sensor 40 is disposed in the ventilation passage, is in communication connection with the control module 20 , and is configured to generate environment data based on the environment in the ventilation passage, and send the environment data to the control module 20 .

[0037] The driving module 50 is connected to the valve 30 and is in communication with the control module 20 , and is configured to be controlled by the control module 20 to drive the valve 30 to close or open the ventilation channel.

[0038] The control module 20 is configured to receive environmental data, determine whether the environmental data is greater than a first threshold, and control the driving module 50 to drive the valve 30 to close the ventilation channel and lock the valve 30 when the environmental data is greater than the first threshold.

[0039] When the valve 30 is locked, the control module 20 is further configured to control the driving module 50 to cancel the locking of the valve 30 when the power connection module 10 is reconnected to the power supply.

[0040] Exemplarily, the power connection module 10 can be any structure or module that can connect to a power source and provide power. For example, the power connection module 10 can include a plug and a connection line. The power connection module 10 can be electrically connected to the control module 20, the environment monitoring sensor 40, and the drive module 50 to provide power to these modules.

[0041] Exemplarily, the control module 20 may include a central processing unit (CPU), or a processor and a memory, wherein the memory may be used to store environmental data and instructions executable by the processor. Exemplarily, the control module 20 may be integrated into a PCB (printed circuit board), a chip, etc., which is not limited here, and may also be replaced by a single-chip microcomputer, and the specific model of the single-chip microcomputer is not limited here.

[0042] For example, the valve 30 may include any valve capable of closing or opening the ventilation passage.

[0043] Specifically, the environment detection sensor 40 is used to detect whether a fire occurs in the ventilation channel, and generates environment data by performing real-time detection of the environment in the ventilation channel. After receiving the environment data, the control module 20 compares the environment data with a preset first threshold value. When the environment data is greater than the first threshold value, the valve control system 1 starts the fire prevention program: the control drive module 50 drives the valve 30 to close the ventilation channel and lock the valve 30; when the valve 30 is locked, when the power connection module 10 reconnects the power supply, the control drive module 50 cancels the lock on the valve 30. Among them, the first threshold value is used as a system standard for judging whether a fire occurs in the ventilation channel, and its specific value can be set according to actual needs, and this embodiment does not make specific limitations.

[0044] Exemplarily, the environment detection sensor 40 may include a combination of one or more of the following items: a temperature sensor, a flame sensor, and a pyroelectric sensor. For example, when the environment detection sensor 40 includes a temperature sensor, the first threshold value may be a temperature value of 150° C. The first threshold value may also be set according to the type of the environment detection sensor 40. The specific type of the environment detection sensor 40 may be set according to the specific application scenario of the environment detection sensor 40, which is not limited in this embodiment.

[0045] Exemplarily, the drive module 50 may include any module or structure that can be connected to the control module 20 for communication and can drive the valve 30 to close or open the ventilation channel. For example, the drive module 50 may include one or more of an electric drive unit, a pneumatic drive unit, and a hydraulic drive unit. For example, the drive module 50 includes a motor.

[0046] Specifically, the driving module 50 locking the valve 30 may refer to keeping the valve 30 at the current working position. Exemplarily, the driving module 50 includes a motor and a motor brake unit. When the valve 30 reaches the desired working position, the motor brake unit may prevent the valve 30 from moving so that the valve 30 remains at the current working position. Exemplarily, the motor brake unit may include a brake.

[0047] In this embodiment, the communication connection may include a wired connection and / or a wireless connection. Exemplarily, the communication connection may include an electrical connection.

[0048] In practical applications, the working process of the valve control system 1 can be as follows: Figure 2 As shown: the power connection module 10 is connected to the power supply; the environment detection sensor 40 generates environment data based on the environment in the ventilation channel, and sends the environment data to the control module 20; the control module 20 receives the environment data, and determines whether the environment data is greater than a first threshold value; when the environment data is greater than the first threshold value, the control drive module 50 drives the valve 30 to close the ventilation channel and lock the valve 30; when the environment data is less than the first threshold value, the control drive module 50 drives the valve 30 to close or open the ventilation channel.

[0049] When the environmental data is greater than the first threshold, the fire prevention program is triggered, the valve 30 closes the ventilation passage and is locked to prevent the valve 30 from being reopened due to external factors such as air flow impact and vibration.

[0050] The valve control system 1 provided in this embodiment, by setting an environmental monitoring sensor 40 in the ventilation channel, performs real-time detection of the environment of the ventilation channel and generates environmental data, and determines whether there is a fire in the ventilation channel by comparing the environmental data with a first threshold through the control module 20. When the environmental data is greater than the first threshold, the valve control system 1 starts the fire prevention program, and the control module 20 controls the drive module 50 to drive the valve 30 to close the ventilation channel and lock the valve 30 to prevent the valve 30 from being reopened due to external factors such as airflow impact and vibration, thereby responding to the fire in time and timely and effectively blocking the fire from spreading through the ventilation channel.

[0051] In addition, after the valve 30 is locked, the power connection module 10 needs to reconnect the power supply to enable the control module 20 to control the drive module 50 to cancel the lock on the valve 30, so that the valve 30 can resume normal working state and normally close or open the ventilation channel to prevent the valve 30 from opening due to incorrect operation or accidental operation, such as opening when the fire is not completely extinguished, thereby affecting the isolation effect of the valve 30, thereby ensuring the accuracy of the position of the valve 30 and improving the safety of use and the effectiveness of fire prevention.

[0052] Figure 6 Shown is a structural schematic diagram of an application scenario suitable for a valve control system provided by another embodiment of the present application.

[0053] like Figure 2 , Figure 3 and Figure 6 As shown, the power connection module 10 includes a socket 11. The socket 11 is provided with a control module 20 and an electrical data acquisition module 60. The control module 20 is in communication connection with the electrical data acquisition module 60.

[0054] The socket 11 is configured to supply power to the ventilation appliance 100. The ventilation appliance 100 is used to allow indoor air to flow into the ventilation passage, and also to allow air in the ventilation passage to flow into the room.

[0055] The electrical data acquisition module 60 is configured to acquire electrical data of the ventilation appliance 100 and send the electrical data to the control module.

[0056] The control module 20 is also configured to receive electrical data and determine whether the electrical data is greater than a second threshold value, and when the environmental data is less than the first threshold value and the electrical data is greater than the second threshold value, control the drive module 50 to drive the valve 30 to open the ventilation channel; when the environmental data is less than the first threshold value and the electrical data is less than the second threshold value, control the drive module 50 to drive the valve 30 to close the ventilation channel.

[0057] For example, a plug of the ventilation appliance 100 may be plugged into the socket 11 , so that the socket 11 supplies power to the ventilation appliance 100 .

[0058] Specifically, the ventilation appliance 100 may include any appliance or system for allowing indoor gas to pass to the ventilation channel and / or allowing the gas in the ventilation channel to pass to the room. For example, the ventilation appliance 100 may include at least one of a range hood, a fresh air system, and a central air conditioning system. Exemplarily, the ventilation appliance 100 has a vent, and the valve 30 is connected to the vent of the ventilation appliance 100. Exemplarily, the electrical data acquisition module 60 is electrically connected to the ventilation appliance 100 to obtain electrical data of the ventilation appliance 100. For example, the electrical data acquisition module 60 is electrically connected to the ventilation appliance 100 via a connecting line 110.

[0059] Exemplarily, the electrical data acquisition module 60 can be integrated into a PCB board, a chip, etc., which is not limited here, and can also be replaced by a single-chip microcomputer. Exemplarily, the electrical data can include at least one of the following items or a combination of multiple items: current, voltage, power, power factor. In the case where the electrical data includes a combination of multiple items in current, voltage, power, and power factor, the second threshold value includes multiple second sub-threshold values, and the multiple second sub-threshold values ​​correspond to the multiple electrical data one by one. Exemplarily, when the multiple electrical data are all greater than the respective corresponding second sub-threshold values, the control drive module 50 drives the valve 30 to open the ventilation channel.

[0060] Exemplarily, the electrical data acquisition module 60 may include a HLW8032 chip and a STC8H1K08 single-chip microcomputer in communication connection. The HLW8032 chip may be configured to acquire the current and voltage of the ventilation appliance 100 in real time. The data in the HLW8032 chip may be transmitted to the STC8H1K08 single-chip microcomputer via a serial port. The STC8H1K08 single-chip microcomputer may be configured to calculate the data received from the HLW8032 chip to acquire the electrical data of the ventilation appliance 100.

[0061] For example, the control module 20 may be configured to control the driving module 50 to drive the valve 30 to close the ventilation passage and lock the valve 30 when the environmental data is equal to the first threshold. In other examples, the control module 20 may be configured to control the driving module 50 to drive the valve 30 to close the ventilation passage when the environmental data is less than or equal to the first threshold and the electrical data is less than or equal to the second threshold. For example, the second threshold may be set according to the electrical data of the ventilation appliance 100 when the valve 30 needs to be opened.

[0062] Exemplarily, the ventilation appliance 100 may include a range hood. The ventilation channel may include a flue. The electrical data acquisition module 60 is used to acquire the power of the range hood. The second threshold value may be greater than the power when only the lighting lamp of the range hood is turned on, and less than or equal to the power when only the motor of the range hood is turned on. When the environmental data is less than the first threshold value, and the power of the range hood is greater than the second threshold value, the drive module 50 drives the valve 30 to open the flue. When the environmental data is less than the first threshold value, and the power of the range hood is less than or equal to the second threshold value, the drive module 50 drives the valve 30 to close the flue.

[0063] refer to Figure 2 As shown, the working process of the valve control system 1 also includes: the electrical data acquisition module 60 acquires the electrical data of the ventilation appliance 100 and sends the electrical data to the control module; the control module 20 receives the electrical data and determines whether the electrical data is greater than a second threshold; when the environmental data is less than the first threshold and the electrical data is greater than the second threshold, the control drive module 50 drives the valve 30 to open the ventilation channel; when the environmental data is less than the first threshold and the electrical data is less than the second threshold, the control drive module 50 drives the valve 30 to close the ventilation channel.

[0064] After the valve 30 is opened or closed, the environment detection sensor 40 will continue to generate environment data based on the environment in the ventilation passage and send it to the control module 20 .

[0065] For example, after the power connection module 10 is connected to the power supply, the working process of the valve control system 1 further includes: the valve control system 1 executes a self-checking program. The self-checking program can be executed by the control module 20.

[0066] The valve control system 1 provided in this embodiment acquires the electrical data of the ventilation appliance 100 by setting an electrical data acquisition module 60, and the control module 20 determines whether the electrical data is greater than a second threshold value, and when the environmental data is less than the first threshold value and the electrical data is greater than the second threshold value, the control drive module 50 drives the valve 30 to open the ventilation channel, and when the environmental data is less than the first threshold value and the electrical data is less than the second threshold value, the control drive module 50 drives the valve 30 to close the ventilation channel, thereby realizing the linkage between the valve control system 1 and the ventilation appliance 100, and can automatically open or close the valve 30 based on the operating status of the ventilation appliance 100, thereby improving the intelligence level of the valve control system 1.

[0067] In addition, the ventilation appliance 100 is powered by the socket 11, which reduces the reserved sockets of the ventilation appliance 100, and is conducive to the linkage between the valve control system 1 and the ventilation appliance 100. Moreover, the control module 20 and the electrical data acquisition module 60 are arranged in the socket 11, which improves the compactness of the structure of the valve control system 1, reduces the use area of ​​the valve control system 1, and improves the user experience.

[0068] In some embodiments, Figures 3 to 5 As shown, the valve 30 is configured to be connected to the ventilation channel. The valve 30 includes a valve plate 31 and a valve body 32 and a base 33 connected to each other.

[0069] The valve body 32 has a first through passage, which is connected to the ventilation passage. The valve plate 31 is disposed in the first through passage, and the valve plate 31 is rotatably connected to the driving module 50 and is configured to be driven by the driving module 50 to rotate so that the valve 30 closes or opens the ventilation passage.

[0070] Exemplarily, the base 33 has a second through-channel, and the first through-channel and the second through-channel are both connected to the ventilation channel. The first through-channel and the second through-channel can form a part of the ventilation channel. Exemplarily, the environment detection sensor 40 is arranged in the first through-channel of the valve body 32, so that it is convenient to install the environment detection sensor 40 and the valve 30 together. Exemplarily, as Figure 5 As shown, the environment detection sensor 40 is disposed in the first through channel and is located on a side of the valve plate 31 close to the base 33 .

[0071] Exemplarily, the ventilation appliance 100 includes a range hood. The air outlet of the range hood is connected to an air duct, and the air duct is connected to the valve 30. Exemplarily, one end of the valve body 32 is connected to the air duct, and the other end of the valve body 32 is connected to the base 33. The side of the base 33 away from the valve body 32 is connected to a wall with a public flue and an air inlet.

[0072] For example, the driving module 50 may be disposed on the valve 30, so that the valve 30 and the driving module 50 are an integrated structure, thereby improving the compactness of the valve control system 1. For example, the driving module 50 may be disposed on the valve body 32.

[0073] In the valve control system 1 provided in this embodiment, the valve 30 includes a valve plate 31 and a valve body 32 and a base 33 which are connected through each other. By setting the valve plate 31 in the first through-channel of the valve body 32, the driving module 50 drives the valve plate 31 to rotate in the first through-channel, so that the valve 30 closes or opens the ventilation channel, so that when the valve plate 31 is parallel to the axial direction of the ventilation channel, the ventilation channel is almost completely opened, reducing wind resistance, and both ends of the valve 30 can allow airflow to pass through, without forming negative pressure, and the valve 30 has a fast opening and closing speed. In addition, the valve 30 also includes a base 33, so that the valve 30 can be easily installed and fixed.

[0074] In some embodiments, the valve plate 31 has a sealing ring on its periphery, which improves the sealing effect of the valve 30 when closing the ventilation channel, and can more effectively block the fire from spreading through the ventilation channel when a fire occurs in the ventilation channel. Exemplarily, the material of the sealing ring includes silicone.

[0075] In some embodiments, the material of the valve includes a fireproof material. The fireproof material may include one or more of a high temperature resistant metal, a high temperature resistant metal alloy, a high temperature resistant polymer, a high temperature resistant ceramic, and a high temperature resistant glass. For example, the material of the valve may include stainless steel.

[0076] In some embodiments, the surface of the valve may have a paint film. The paint film may be prepared on the surface of the valve using electrophoretic paint film technology. This arrangement can improve the appearance of the valve 30 and protect the surface of the valve 30, thereby having an anti-corrosion effect.

[0077] Figure 7 Shown is a structural schematic diagram of an application scenario suitable for a valve control system provided by yet another embodiment of the present application.

[0078] like Figure 7 As shown, at least one signal light 70 is provided on the power connection module 10. The signal light 70 is in communication connection with the control module 20. The signal light 70 indicates in at least two display modes: the valve 30 opens the ventilation channel and the valve 30 closes the ventilation channel. By providing the signal light 70, the user can be easily informed of the working status of the valve 30 in a timely manner, thereby improving the user experience.

[0079] Exemplarily, the signal light 70 indicates in four display modes: the valve 30 opens the ventilation channel, the valve 30 closes the ventilation channel and the valve 30 is not locked, the valve 30 is locked, and the valve 30 fails. Exemplarily, two signal lights 70 are provided on the power connection module 10. The two signal lights 70 are respectively configured to emit red light and green light. The two signal lights 70 are always on, which can indicate that the valve 30 opens the ventilation channel. The signal light 70 that only emits green light is always on, which can indicate that the valve 30 closes the ventilation channel and the valve 30 is not locked. The signal light 70 that only emits red light is always on, which can indicate that the valve 30 is locked. Both signal lights 70 are not always on, which indicates that the valve 30 fails.

[0080] The above describes in detail the embodiment of the valve control system 1 of the present application, and the following describes in detail the embodiment of the ventilation electrical system of the present application. It should be understood that the description of the embodiment of the valve control system 1 corresponds to the description of the embodiment of the ventilation electrical system, and therefore, the parts not described in detail can refer to the above embodiment of the valve control system 1.

[0081] An embodiment of the present application provides a ventilation appliance system, which includes: a ventilation appliance 100 , a valve control system 1 mentioned in any of the above embodiments, and a connecting line 110 .

[0082] The ventilation appliance 100 is used to allow indoor air to flow into the ventilation channel, and / or to allow air in the ventilation channel to flow into the room. The connection line 110 connects the ventilation appliance 100 and the electrical data acquisition module 60 of the valve control system 1 to acquire electrical data of the ventilation appliance.

Exemplarily, the ventilation electrical system may further include an air duct to form part of the ventilation channel.

[0084] Exemplarily, the ventilation appliance 100 may include a range hood. Since grease particles accumulate in the flue of the range hood for a long time to form oil stains, when a fire occurs in the ventilation passage, it is easier to spread in the flue. Therefore, it is very necessary to control the opening and closing of the flue through the valve control system 1.

[0085] The ventilation electrical system provided in this embodiment detects the environment of the ventilation channel in real time and generates environmental data by setting an environmental monitoring sensor 40 in the ventilation channel. The control module 20 compares the environmental data with a first threshold to determine whether there is a fire in the ventilation channel. When the environmental data is greater than the first threshold, the valve control system 1 starts the fire prevention program, and the control module 20 controls the drive module 50 to drive the valve 30 to close the ventilation channel and lock the valve 30 to prevent the valve 30 from being reopened due to external factors such as airflow impact and vibration, thereby responding to the fire in a timely manner and promptly and effectively blocking the spread of the fire through the ventilation channel.

[0086] In addition, after the valve 30 is locked, the power connection module 10 needs to reconnect the power supply to enable the control module 20 to control the drive module 50 to cancel the lock on the valve 30, so that the valve 30 can resume normal working state and normally close or open the ventilation channel to prevent the valve 30 from opening due to incorrect operation or accidental operation, such as opening when the fire is not completely extinguished, thereby affecting the isolation effect of the valve 30, thereby ensuring the accuracy of the position of the valve 30 and improving the safety of use and the effectiveness of fire prevention.
