[0057] To further illustrate the technical means and effects employed by the present invention to achieve the intended objectives of the embodiments, the following, in conjunction with the accompanying drawings and preferred embodiments, describes in detail the specific implementation, structure, features, and effects of the dual-channel air ventilation and purification device and ventilation valve and operating method thereof according to the embodiments of the present invention. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0058] Figures 1 to 11 For an embodiment of the ventilation and purification device provided by the present invention, please refer to Figures 1 to 11 A ventilation and purification device provided in one embodiment of the present invention includes at least: a purification component 10 and a purification fan 20.

[0059] The purification component 10 includes a first air flow channel and a second air flow channel.

[0060] The first airflow channel is provided with a polluted gas purification unit, which can be used to purify harmful gases in the air. This unit serves as a purification channel 11, and is provided with a purification valve 31. The specific material and structure can be determined according to the type of polluted gas to be filtered. It can be set to filter a single type of harmful gas, or it can be set to filter at least two types of harmful and hazardous gases as required. The second airflow channel can serve as a channel for direct airflow, serving as a ventilation channel 12, and is provided with a ventilation valve 32.

[0061] The air outlet side of the purification fan 20 leads to the inlet of the ventilation channel 12 and the inlet of the purification channel 11 .

[0062] Two air flow channels are provided in the purification component 10. When the air needs to be ventilated separately, the ventilation valve 32 can be opened, the purification valve 31 can be closed, and the purification fan 20 can be turned on. The air volume can be discharged from the outlet of the ventilation channel 12 to realize the ventilation mode. When the air needs to be purified separately, the ventilation valve 32 can be closed, the purification valve 31 can be opened, and the purification fan 20 can be turned on. The air volume can be purified by the polluted gas purification unit of the purification channel and discharged to realize the purification mode. Compared with the prior art, the ventilation and purification device provided in this embodiment can realize the dual functions of ventilation and polluted gas purification. It can be assembled in a safety isolation tent. Only one set of equipment needs to be assembled, which is easy to assemble.

[0063] The first and second airflow channels are independent channels and can be arranged adjacent to each other, that is, separated by a barrier. The first airflow channel is used to filter polluted gases, and the second airflow channel is used when polluted gases are not required. The first and second airflow channels can be arranged in a stacked or annular manner. For example, the second airflow channel is an annular airflow channel surrounding the outer periphery of the first airflow channel.

[0064] The first end plate 110 at the outlet end of the first air flow channel has a first air outlet 111, and the air inlet end of the first air flow channel has a first air inlet 112, which serves as the entrance to the purification channel 11; the second end plate 120 at the outlet end of the second air flow channel has a second air outlet 121, and the air inlet end of the second air flow channel has a second air inlet 122, which serves as the entrance to the ventilation channel 12; the second air flow channel surrounds the outer periphery of the first air flow channel, and the second air flow channel can be an integral annular air flow channel, or can include multiple independent air flow channels. In implementation, the second air inlet 122 of each independent air flow channel is connected, serving as the entrance to the ventilation channel 12. There is an air flow gap space between the first end plate 110 and the second end plate 120, and the air flow gap space is respectively connected to each independent second air flow channel 12, the first air outlet 111, and the second air outlet 121. Among them, the second air outlet 121 can serve as the total air outlet of the purification component 10, and different ventilation channels can be selected by adjusting the opening and closing of the ventilation valve 32 and the purification valve 31.

[0065] In practice, the outlet of the ventilation channel 12 and the outlet of the purification channel 11 can be connected to a unified outlet, and the unified outlet can be connected to the safety isolation tent, so as to provide clean and safe air for the people in the safety isolation tent.

[0066] The purification fan 20 includes a motor 21 and a blade area 22. The blade area 22 is arranged on the drive shaft of the motor 21 and generates airflow according to the driving rotation of the drive shaft. The air outlet formed by the blade area 22 is sealed and connected to the inlet of the ventilation channel 12 and the inlet of the purification channel 11.

[0067] The ventilation and purification device proposed in one embodiment of the present invention, based on the ventilation and purification device provided in the above embodiment, may further include: a filter component 40. The filter component 40 has a filter air inlet and a filter air outlet, and the air inlet side of the purification fan 20 can be connected to the filter air outlet of the filter component 30. Therefore, when it is necessary to filter the air separately, the ventilation valve 32 can be opened, the purification valve 31 can be closed, and the purification fan 20 can be turned on. The air volume can be filtered by the filter component 30 for particulate matter, and then discharged from the outlet of the ventilation channel 12 to realize the filtering mode. When it is necessary to purify the air, the ventilation valve 32 can be closed, the purification valve 31 can be opened, and the purification fan 30 can be turned on. The air volume can be filtered by the filter component 30 for particulate matter, and then purified by the polluted gas purification unit of the purification channel 11 and discharged to realize the purification mode.

[0068] The filter component 40 may include a cyclone filter chamber 41, an exhaust fan 42, and a exhaust pipe 43. The cyclone filter chamber 41 includes an air inlet chamber 411, a dust collecting chamber 412, an exhaust chamber 413 and a cyclone filter 414. The air inlet chamber 411 is provided with an air inlet, the air inlet of the cyclone filter 414 is arranged in the air inlet chamber 411, the dust exhaust port of the cyclone filter 414 is arranged in the dust collecting chamber 412, and the air exhaust port of the cyclone filter 414 is arranged in the exhaust chamber 413; the air inlet of the exhaust fan 42 is connected to the dust collecting chamber 412, the first end of the exhaust pipe 43 is connected to the exhaust port of the exhaust fan 42, and the second end of the exhaust pipe 43 can be led to the outside of the air inlet set in the air inlet chamber 411; the air inlet side of the purification fan 20 is connected to the exhaust chamber 413.

[0069] The air inlet of the air inlet chamber 413 can be provided with a sealing cover to prevent external gas from entering the air inlet chamber 413 when ventilation and purification are not needed. The sealing cover can be opened and covered on the outside of the air inlet chamber 413.

[0070] In some embodiments, the second end of the drainage pipe 43 can be used to discharge dust through an independent drainage port defined in the filter element 40. In some embodiments, dust can also be discharged through the air inlet provided in the air inlet chamber 411. When the sealing cover is opened, the second end of the drainage pipe 43 can be directed to the air inlet provided in the air inlet chamber 411. The directions of the air inlet of the air inlet chamber 411 and the drainage port at the second end of the drainage pipe 43 can be different.

[0071] When ventilation and purification are not needed, the second end of the sewage pipe 43 can be set in the air inlet chamber 411, and the sealing cover simultaneously seals the air inlet of the air inlet chamber 411 and the second end of the sewage pipe 43 (the air inlet of the air inlet chamber and the second end of the sewage pipe are sealed in the sealed space formed between the sealing cover and the air inlet chamber).

[0072] The number of the cyclone filters 414 is not limited to one, and may be one or more. For example, a plurality of cyclone filters 414 are arranged in parallel.

[0073] The cyclone filter 414 includes an air duct 4141 and a conical barrel 4142. A cyclone impeller is disposed within the first end of the air duct 4141. The first port of the conical barrel 4142 extends into the second end of the air duct 4141. The first port of the conical barrel 4142 is smaller than the second port of the conical barrel 4142. The air inlet chamber 411, the dust collection chamber 412, and the exhaust chamber 413 are arranged sequentially. The air inlet of the first end of the air duct 4141 is disposed in the air inlet chamber 411, the second end of the air duct 4141 is disposed in the dust collection chamber 412, and the second port of the conical barrel 4142 is disposed in the exhaust chamber 413. The cyclone impeller can be fixed to the first end of the air duct 4141 or can be integrally formed within the first end of the air duct 4141. The specific form of the impeller is not limited.

[0074] During operation, the outside air enters the air inlet chamber 411 from the air inlet of the air inlet chamber 411, and after passing through the cyclone impeller inside the first end of the air duct 4141, a cyclone is generated in the air duct 4141, and the particulate matter with increased weight is swirled to the inner wall of the air duct 4141, and discharged to the dust collecting chamber 412 through the gap between the inner wall of the port at the second end of the air duct 4141 and the outer wall of the first port of the conical cylinder 4142. The lighter clean air flows from the center of the air duct 4141 through the first port of the conical cylinder 4142, and enters the exhaust chamber 413 through the second port of the conical cylinder 4142, thereby completing the screening of particulate matter in the air.

[0075] The air inlet formed by the fan blade area 22 is connected to the exhaust chamber 413. When the purification fan 20 is in operation, a negative pressure area is formed on the air inlet side of the purification fan 20, and a positive pressure area is formed on the air outlet side of the purification fan 20. In the purification mode, the ventilation valve 32 is closed and the purification valve 31 is open. Since the outlet of the ventilation channel 12 and the outlet of the purification channel 11 are connected, if the ventilation valve 32 is not sealed tightly, unpurified air will leak from the ventilation channel 32 and be transported to the safety isolation tent. This leads to excessively high sealing requirements for the ventilation valve 32, significantly increasing production costs. In some embodiments, the ventilation valve 32 may include a first valve disposed at the inlet of the ventilation channel 12 and a second valve disposed at the outlet of the ventilation channel, thereby improving the sealing effect by using two valves. In addition, in the purification mode, when the first valve and the second valve are closed, clean positive pressure gas can be introduced into the ventilation channel 12 between the first valve and the second valve, so that the pressure in the ventilation channel 12 between the first valve and the second valve is greater than the pressure in the purification channel, thereby preventing leakage of contaminated gas from the first valve into the ventilation channel 12. In addition, in the purification mode, the first valve and the second valve are closed, and a negative pressure pipeline can be applied to the ventilation channel 12 between the first valve and the second valve so that the pressure of the ventilation channel 12 between the first valve and the second valve is lower than the pressure of the purification channel, so that the polluted gas leaking from the first valve into the ventilation channel 12 can be discharged through the negative pressure pipeline.

[0076] The inventors found that if a dual-channel structure is used to achieve ventilation and purification functions, and a manual valve in the ventilation channel is used, personnel still need to manually close the manual valve in the ventilation channel during the process of switching from the ventilation function to the purification function, which is inconvenient to operate.

[0077] Figures 12 to 14 This is an embodiment of the present invention, based on the ventilation and purification device described in the above embodiment, please refer to Figures 12 to 14 The ventilation valve 32 of the dual-channel air ventilation and purification device proposed in one embodiment of the present invention includes:

[0078] A valve base 34, wherein the valve base 34 is provided with a valve port;

[0079] The valve core body 321 is arranged at the valve port;

[0080] The operating member 322 is connected to the valve core body 321 and is used to receive a rotational force from an external operation. The operating member 322 transmits the rotational force to the valve core body 321, so that the valve core body 321 changes from a closed state at the valve port to an open state at the valve port.

[0081] a force storage component 323 connected to the operating component, for receiving and storing the rotational force exerted by the operation through the operating component;

[0082] The electrically controlled locking component 324 is used to lock the operating component 322 to restrict the rotation of the operating component 322 and to release the locking of the operating component 322 by electrically controlling the electrically controlled locking component 324 .

[0083] In the technical solution provided by the embodiment of the present invention, in the ventilation mode, an operator can manually apply a rotational force to the operating component, which is stored in the force storage component, causing the valve core body to transition from a closed state (closed to the valve port) to an open state (open to the valve port), thereby opening the ventilation valve 32 of the ventilation channel 12 in the dual-channel air ventilation and purification device. When it is necessary to switch from the ventilation function to the purification function, the force storage component stores the rotational force, allowing the electronically controlled locking component to be remotely controlled to release the lock on the operating component. Under the action of the rotational force stored in the force storage component, the operating component is driven to rotate, causing the valve core body to transition from an open state (open to the valve port) to a closed state (closed to the valve port). Compared to the prior art, the switch from ventilation mode to purification mode is safe and does not require manual on-site operation. Therefore, when switching from ventilation mode to purification mode, it is no longer necessary for personnel to manually close the manual valve in the ventilation channel 12, making operation more convenient.

[0084] The structure of the valve core body cooperates with the structure of the valve port of the valve base 34 to form a valve that can be opened and closed. In different embodiments, in the valve that realizes opening and closing, the valve core body can be a valve plate structure that independently rotates within the valve port, or a valve plate structure that independently moves within the valve port, or the valve core body can be a valve plate structure that simultaneously rotates and moves within the valve port to realize the opening and closing functions of the valve. In this embodiment, only the valve plate structure is used as an example. It is easy to understand that in practice, the embodiments of the present application are not limited to the valve plate structure.

[0085] The operating component 322 includes a rotating shaft, and the valve core body 321 is a valve plate arranged on the rotating shaft. By rotating the operating shaft, the valve plate can open and close the valve port. In order to implement the operating steps of the operating component, the rotating shaft can be rotatably arranged on the valve base 34, and one end of the rotating shaft is exposed as the operating end. It should be noted that the rotating shaft is not limited to the first rotating shaft part, and should be understood to include at least one shaft. In practice, it can be understood as a rotating shaft mechanism including an axis, or an axis mechanism connected by multiple axes or multiple transmission mechanisms, which can realize the operating mechanism of the valve plate.

[0086] The ventilation channel 12 is arranged on the periphery of the purification channel 11 and is an annular ventilation channel. The ventilation channel 12 can have two entrances, which are arranged on both sides of the entrance of the purification channel 11. The two entrances of the corresponding ventilation channel 12 are both provided with ventilation valves 32.

[0087] The valve base 34 is a rectangular bottom shell with a rectangular side wall on the periphery of the rectangular bottom shell; the purge valve 31 and the ventilation valves 32 located on both sides of the purge valve 31 are arranged in a straight line on a diagonal line in the rectangular shell bottom 34; the rotating shaft includes a first shaft 325, a second shaft 326, a universal coupling 327, and a third shaft 328; the valve plate 311 of the purge valve 31 and the valve plates 321 of the ventilation valve 32 located on both sides of the purge valve 31 are arranged on the first shaft 325; the second shaft 326 and the first The shaft 325 is connected via a worm gear cross drive; the first end of the third shaft 328 is connected to the first end of the second shaft 326 via the universal coupling 327. The second end of the third shaft 328 is perpendicular to the first side wall of the rectangular side wall. The operating end is the second end of the third shaft 328. The first side wall is provided with a control hole 327. The second end of the third shaft 328 is an inner polygonal socket or an outer polygonal plug, extending into the control hole. The inner polygonal socket or outer polygonal plug is exposed through the control hole. In this embodiment, by arranging the valve plate 311 of the purge valve 31 and the valve plates 321 of the ventilation valve 32 located on both sides of the purge valve 31 on a diagonal line of the rectangular bottom shell, the positions of the three valves can be compactly arranged compared to the horizontal and vertical arrangement of the three valves. At the same time, the worm gear and universal coupling 327 can make the operating end perpendicular to the side wall of the rectangular bottom shell, facilitating the application of rotational force to the inner polygonal socket or outer polygonal plug through the control hole by an external tool. When the operating end is operated to rotate to a first angle, the valve plate seals the ventilation channel 12 . When the operating end is operated to rotate to a second angle, the valve plate releases the seal on the ventilation channel 12 .

[0088] The force storage component 323 can be an elastic material element to achieve the storage of rotational force, for example, a torque spring or an elastic rope. Taking the torque spring as an example, the torque spring is sleeved on the rotating shaft, the first end of the torque spring is fixed to the valve base 34, and the second end of the torque spring is fixed to the rotating shaft.

[0089] The electrically controlled locking member 324 can be used to lock the operating member 322 to restrict the forward and reverse rotation of the operating member 322. When the dual-channel air ventilation and purification device is in ventilation mode, it is necessary to first electrically control the electrically controlled locking member 324 to release the locking of the operating member 322. Then, a rotational force is applied to the operating member 322 to shift the valve core 321 from a closed state (closed to the valve port) to an open state (open to the valve port).

[0090] Among them, the above-mentioned operation process is relatively cumbersome. In order to simplify the operation steps, the following implementation method can be adopted: wherein, the operating component 322 is used to receive the first direction rotational force of the external operation, and the operating component 322 transmits the first direction rotational force to the valve core body 321, so that the valve core body 321 changes from the closed state closed to the valve port to the open state opened to the valve port; the electric control locking component 324 is used to lock the operating component 322 to limit the rotation of the second direction of the operating component 322, and release the lock on the second direction rotation of the operating component 322 by electric control operation of the electric control locking component 324.

[0091] In a specific implementation, the following structure can be used, but is not limited to the following specific structure: the electrically controlled locking component 324 includes: an electric drive mechanism 3241, a ratchet 3242, and a pawl 3243; the ratchet 3242 is disposed on the rotating shaft, the pawl 3243 is disposed on the valve base 34, and the pawl 3243 is one-way engaged with the ratchet 3242; the electric drive mechanism 3241 is used to drive the pawl 3243 to separate from the ratchet 3242. The electric drive mechanism 3241 includes: a motor, the motor is disposed on the valve base 34, and the output shaft of the motor is provided with a paddle. When the output shaft of the motor rotates from a first angle to a second angle, the paddle drives the pawl 3243 to separate from the ratchet 3242. When the ventilation mode of the dual-channel air ventilation and purification device is implemented, the ratchet 3242 and the pawl 3243 are used in combination, and the electrically controlled locking component does not limit the rotation of the operating component in the first direction. It is no longer necessary to electrically control the electrically controlled locking component to release the lock of the operating component. A rotational force in the first direction can be directly applied to the operating component to change the valve core body from a closed state closed to the valve port to an open state open to the valve port, and the operation process is more convenient.

[0092] Based on the same invention technology concept, Figures 12 to 14 An embodiment of the present invention is based on the ventilation and purification device described in the above embodiment, please refer to Figures 12 to 14 An embodiment of the present invention provides a dual-channel air ventilation and purification device, comprising:

[0093] The filter component 40 has an exhaust chamber 413 for discharging filtered particulate matter;

[0094] The purification component 10 includes a ventilation channel 12 and a purification channel 11 arranged in parallel;

[0095] The ventilation valve 32 includes: a valve base 34, a valve core body 321, an operating component 322, a force storage component 323 and an electronically controlled locking component 324, wherein the valve base 34 is provided with a valve port; the valve core body 321 is provided at the valve port; the operating component 322 is connected to the valve core body 321 and is used to receive the rotational force of external operation, and the operating component 322 transmits the rotational force received to the valve core body 321, so that the valve core body 321 changes from a closed state closed at the valve port to an open state open at the valve port; the force storage component 323 is connected to the operating component 322 and is used to receive and store the rotational force received by the operation through the operating component 322; the electronically controlled locking component 324 is used to lock the operating component 322 to limit the rotation of the operating component 322, and release the lock of the operating component 322 by electronically operating the electronically controlled locking component 324. The ventilation valve 32 is provided in the ventilation channel 12.

[0096] The purge valve 31 is provided in the purge channel 11;

[0097] The purification fan 20 has an air inlet side connected to the exhaust chamber 413 , and an air outlet side connected to the inlet of the ventilation channel 12 and the inlet of the purification channel 11 .

[0098] In the technical solution provided by the embodiment of the present invention, in the ventilation mode, an operator can manually apply a rotational force to the operating component, which is stored in the force storage component, causing the valve core body to transition from a closed state (closed to the valve port) to an open state (open to the valve port), thereby opening the ventilation valve 32 of the ventilation channel 12 in the dual-channel air ventilation and purification device. When it is necessary to switch from the ventilation function to the purification function, the force storage component stores the rotational force, allowing the electronically controlled locking component to be remotely controlled to release the lock on the operating component. Under the action of the rotational force stored in the force storage component, the operating component is driven to rotate, causing the valve core body to transition from an open state (open to the valve port) to a closed state (closed to the valve port). Compared to the prior art, the switch from ventilation mode to purification mode is safe and does not require manual on-site operation. Therefore, when switching from ventilation mode to purification mode, it is no longer necessary for personnel to manually close the manual valve in the ventilation channel 12, making operation more convenient.

[0099] The operating end can be a manual knob or other operating structure. For example, in order to make it concealed and operable by professional tools, the operating end is a polygonal operating column or polygonal operating hole located in the hole on the outer wall of the purification component 10. During operation, the operator needs to use an inner polygonal end operating tool or an outer polygonal end operating tool to insert into the hole on the outer wall of the purification component 10, and twist the operating end of the polygonal operating column or polygonal operating hole to open and close the valve core body. When the operating end is operated to rotate to a first angle, the valve core body seals the ventilation channel 12. When the operating end is operated to rotate to a second angle, the valve core body releases the seal on the ventilation channel 12.

[0100] During assembly of the dual-channel air ventilation and purification device, the valve base 34 is disposed between the air outlet side of the purification fan 20 and the inlet of the ventilation channel 12 .

[0101] Based on the same invention technology concept, Figure 15 This is an embodiment of the present invention, based on the ventilation and purification device described in the above embodiment, please refer to Figure 15 An operating method of a dual-channel air ventilation and purification device according to an embodiment of the present invention includes:

[0102] Operation steps of air ventilation mode:

[0103] A10 applies a rotational force to the operating component and stores the rotational force in the force storage component, thereby causing the valve core body to change from a closed state closed to the valve port to an open state opened to the valve port, thereby opening the ventilation valve of the ventilation channel in the dual-channel air ventilation and purification device;

[0104] In some embodiments, an electrically controlled locking component can be used to lock the operating component to restrict rotation of the locking component in both forward and reverse directions. Before performing step A10 of implementing the ventilation mode for the dual-channel air ventilation and purification device, it is necessary to first electrically control the electrically controlled locking component to release the locking of the operating component. Thereafter, a rotational force is applied to the operating component to cause the valve core body to transition from a closed state (closed to the valve port) to an open state (open to the valve port).

[0105] In some embodiments, the operating component is used to receive a rotational force in a first direction from an external operation, and the operating component transmits the rotational force in the first direction to the valve core body, causing the valve core body to transition from a closed state, closed to the valve port, to an open state, open to the valve port; the electrically controlled locking component is used to lock the operating component to limit the rotation of the operating component in a second direction, and to release the lock on the rotation of the operating component in the second direction through an electrically controlled operation. Before performing step A10 of implementing the ventilation mode for the dual-channel air ventilation and purification device, it is no longer necessary to electrically control the electrically controlled locking component to release the lock on the operating component. The rotational force in the first direction can be directly applied to the operating component to transition the valve core body from a closed state, closed to the valve port, to an open state, open to the valve port, making the operation process more convenient.

[0106] A20 closes the purification valve of the purification channel in the dual-channel air ventilation purification device;

[0107] Among them, in the implementation of the purification valve of the purification channel, an electronically controlled purification valve can be used, the switch of the electronically controlled purification valve can be controlled by remote control, or a manual purification valve can be used, and the operator can reach the location of the dual-channel air ventilation purification device to manually operate the switch of the manual purification valve.

[0108] A30 turns on the purification fan blowing air toward the inlet side of the ventilation channel and the inlet side of the purification channel, so that the air from the air inlet side of the purification fan enters the ventilation channel;

[0109] Air purification mode operation steps:

[0110] A40 electrically controls the electrically controlled locking component to release the locking of the locking component, and drives the operating component to rotate under the action of the rotational force stored in the force storage component, so as to change the valve core body from an open state opened at the valve port to a closed state closed at the valve port;

[0111] A50 opens the purification valve of the purification channel in the dual-channel air ventilation purification device;

[0112] A60 turns on the purification fan that blows air toward the inlet side of the ventilation channel and the inlet side of the purification channel, so that the air to be purified on the air inlet side of the purification fan enters the ventilation channel.

[0113] In the technical solution provided by the embodiment of the present invention, in the ventilation mode, the operator can manually apply a rotational force to the operating component, and the rotational force is stored in the force storage component, so that the valve core body is changed from a closed state closed to the valve port to an open state opened to the valve port, so as to open the ventilation valve of the ventilation channel in the dual-channel air ventilation and purification device. When it is necessary to switch from the ventilation function to the purification function, since the force storage component stores the rotational force, the electric control locking component can be remotely controlled to release the lock on the operating component. Under the action of the rotational force stored in the force storage component, the operating component is driven to rotate so that the valve core body is changed from the open state opened to the valve port to the closed state closed to the valve port. Compared with the prior art, since the switch from the ventilation mode to the purification mode is safe, no manual operation is required on site. Therefore, when switching from the ventilation function to the purification function, it is no longer necessary for personnel to manually close the manual valve in the ventilation channel, which is more convenient to operate.
