[0047] Reference below Figure 1-Figure 8 A clothes treating device according to an embodiment of the present invention is described.

[0048] The laundry processing apparatus according to the embodiment of the present invention may include: a laundry processing drum assembly 300 and an air duct assembly 200 .

[0049] The clothing treatment drum assembly 300 defines a clothing treatment chamber 30, which has a first air inlet 301 and a first air outlet 302. The air duct assembly 200 is disposed above the clothing treatment drum assembly 300 and defines an air duct chamber 20, which has a second air inlet 201 and a second air outlet 202, wherein the first air outlet 302 is communicated with the second air inlet 201, and the first air inlet 301 is communicated with the second air outlet 202. That is, the airflow in the clothing treatment chamber 30 flows out of the clothing treatment chamber 30 through the first air outlet 302, enters the air duct chamber 20 through the second air inlet 201, flows along the air duct chamber 20, flows out of the air duct chamber 20 through the second air outlet 202 after being processed by various structures in the air duct chamber 20, and then enters the clothing treatment chamber 30 through the first air inlet 301 to participate in the clothing treatment in the clothing treatment chamber 30.

[0050] During the operation of the clothing treatment device, due to the high-speed operation of the inner drum, dirty water will splash into the air duct cavity 20 through the first air outlet 302 and the second air inlet 201, affecting the user experience. In addition, during the assembly of the structure in the air duct cavity 20, there are parts that are easy to fall off, such as screws. These parts may fall into the clothing treatment drum assembly 300 through the second air inlet 201 and the first air outlet 302, affecting the operation of the device. To this end, the embodiment of the utility model designs a clothing treatment device with a one-way valve 10 added between the first air outlet 302 and the second air inlet 201. Thus, when the clothing treatment device does not need a ventilation function, dirty water can be prevented from entering the air duct cavity 20, and foreign matter in the air duct cavity 20 can also be prevented from entering the clothing treatment cavity 30, thereby improving the user experience. When the clothing treatment device supplies air to the clothing treatment cavity 30 through the air duct assembly 200, the one-way valve 10 can allow air to flow from the first air outlet 302 to the second air inlet 201, and the ventilation function of the clothing treatment device can operate normally.

[0051] Specifically, the first air outlet 302 is connected to the second air inlet 201 through the air flow channel 40, wherein the air flow channel 40 can be defined by the structure of the clothing processing drum assembly 300 itself, or by the structure of the air duct assembly 200 itself, or can be defined by a structure independent of the clothing processing drum assembly 300 and the air duct assembly 200, or can be defined by any two structures of the clothing processing drum assembly 300, the air duct assembly 200, and a structure independent of the clothing processing drum assembly 300 and the air duct assembly 200, or can be defined by the air flow channel 40 by the structures of all three.

[0052] A one-way valve 10 is disposed at the airflow channel 40 , that is, the one-way valve 10 can be disposed in the airflow channel 40 , or the one-way valve 10 can be disposed at one end of the airflow channel 40 .

[0053] The one-way valve 10 is constructed to only allow air flow from the first air outlet 302 to the second air inlet 201. Therefore, when the fan of the air duct assembly 200 is running and the air flow between the air duct cavity 20 and the clothing processing cavity 30 begins to circulate, the one-way valve 10 opens to allow air flow from the first air outlet 302 to the second air inlet 201, ensuring the normal circulation of the air flow. When the fan of the air duct assembly 200 is not running, the one-way valve 10 is closed, and sewage or impurities in the clothing processing cavity 30 cannot enter the air duct cavity 20 through the air flow channel 40, and impurities in the air duct cavity 20 cannot enter the clothing processing cavity 30 through the air flow channel 40, thereby improving the user experience.

[0054] According to the clothing processing device of the embodiment of the utility model, the clothing processing device can ensure normal ventilation of the air flow channel 40 while isolating the clothing processing chamber 30 and the air duct chamber 20 when the ventilation function is not needed, thereby preventing foreign matter from entering the clothing processing chamber 30 and sewage from entering the air duct chamber 20, thereby improving the user experience.

[0055] The clothing processing device also includes a filter component 203, which is at least partially disposed in the air duct cavity 20, and the filter component 203 is disposed near the second air inlet 201, and is used to filter the airflow entering the air duct cavity 20 from the second air inlet 201. That is to say, the filter component 203 is disposed in the air duct cavity 20 at an upstream portion of the flow channel defined by the air duct cavity 20, thereby the filter component 203 can filter impurities such as dander in the airflow before the airflow contacts other structures in the air duct cavity 20, thereby preventing the airflow from carrying impurities such as dander to other structures in the air duct cavity 20, such as around the evaporator or condenser, thereby affecting the heat exchange effect and affecting the service life of the clothing processing device.

[0056] That is to say, the airflow in the clothing processing chamber 30 flows out of the clothing processing chamber 30 through the first air outlet 302, enters the air duct chamber 20 through the second air inlet 201, passes through the filter component 203, and is filtered and processed at the filter component 203, and continues to flow along the air duct chamber 20. After being processed by various structures in the air duct chamber 20, it flows out of the air duct chamber 20 through the second air outlet 202, and then enters the clothing processing chamber 30 through the first air inlet 301, and participates in the clothing processing in the clothing processing chamber 30.

[0057] Since the filter assembly 203 often needs to be disassembled for filter replacement and cleaning, the air duct cavity 20 is open during the disassembly and assembly of the filter assembly 203, and foreign matter such as children's toy marbles may pass through the installation of the filter assembly through the second air inlet 201 and the first air outlet 302 and fall into the clothing treatment cavity 30. Therefore, a one-way valve 10 is added between the first air outlet 302 and the second air inlet 201, which can also isolate the filter assembly 203 from the clothing treatment cavity 30 to prevent foreign matter from entering the clothing treatment cavity 30, thereby improving the user experience.

[0058] In some embodiments, the one-way valve 10 may also be disposed in the air duct assembly 200, between the second air inlet 201 and the filter assembly 203, and be constructed to only allow air flow from the second air inlet 201 to the filter assembly 203. Alternatively, the one-way valve 10 may also be disposed in the clothing processing drum assembly 300, and be disposed at a joint position formed by the clothing processing drum assembly 300 extending outward, both of which may achieve isolation between the air duct cavity 20 and the clothing processing cavity 30, which is not limited here.

[0059] In other embodiments, the one-way valve 10 may also be arranged between the second air outlet 202 of the air duct assembly 200 and the first air inlet 301 of the clothing processing drum assembly 300, and be constructed to only allow air flow from the second air outlet 202 to the first air inlet 301, and can also achieve isolation between the air duct cavity 20 and the clothing processing cavity 30.

[0060] Specifically, refer to Figure 2 The one-way valve 10 includes: a blocking member, which is arranged at the airflow channel 40. The blocking member can be arranged in the airflow channel 40, or the blocking member can be arranged at one side end of the airflow channel 40, and the blocking member has a conducting state and a disconnecting state.

[0061] When the blocking member is in the on state, the airflow channel 40 is connected to the first air outlet 302 and the second air inlet 201 , and when the blocking member is in the off state, the airflow channel 40 disconnects the first air outlet 302 and the second air inlet 201 .

[0062] Therefore, the one-way valve 10 can selectively control the blocking member to switch between the on state and the off state. When the air duct assembly 200 starts to run, that is, when the fan in the air duct assembly 200 starts to run, the blocking member of the one-way valve 10 is synchronously controlled to switch from the off state to the on state. At this time, the air duct cavity 20 and the clothing processing cavity 30 are connected, and the airflow can flow from the first air outlet 302 to the second air inlet 201. After passing through the air duct cavity 20, it flows from the second air outlet 202 to the first air inlet 301 and returns to the clothing processing cavity 30. The airflow circulates between the air duct cavity 20 and the clothing processing cavity 30.

[0063] When the air duct assembly 200 stops running, that is, when the fan in the air duct assembly 200 stops running, the blocking member of the synchronously controlled one-way valve 10 is switched from the on state to the off state. When the blocking member is in the off state, the air duct cavity 20 and the clothing processing cavity 30 can be separated to avoid material exchange between the two. For example, sewage in the clothing processing cavity 30 can be prevented from splashing into the air duct cavity 20, or parts in the air duct cavity 20 can be prevented from falling off. Foreign matter that enters the air duct cavity 20 from the outside enters the clothing processing cavity 30 through the air flow channel 40, thereby improving the user experience.

[0064] Among them, the driving method of the blocking part can directly utilize wind force, the blocking part's own gravity, spring elastic force, etc. Therefore, there is no need to set up an independent structure in the clothing processing device to control and drive the state switching of the blocking part. The blocking part can switch the state automatically under the action of wind force and gravity, which simplifies the structure and facilitates control.

[0065] In some embodiments, the center of gravity height of the blocking piece in the on state is higher than the center of gravity height of the blocking piece in the off state. Therefore, under the action of gravity, the blocking piece always tends to move toward the off state position, and in the absence of external force, the blocking piece remains in the off state.

[0066] Therefore, when the air duct assembly 200 starts to run, the blocking part of the synchronously controlled one-way valve 10 switches from the disconnected state to the on state. At this time, there is an external force acting on the blocking part, so that it overcomes the effect of gravity and switches from the disconnected state to the on state. During the operation of the air duct assembly 200, the force always acts on the blocking part until the air duct assembly 200 stops running and the blocking part loses the effect of the external force. The blocking part is suitable for switching from the on state to the disconnected state under the action of gravity.

[0067] In some embodiments, the external force that drives the blocking member to switch from the disconnected state to the conductive state may be a magnetic force. In this case, the blocking member may be constructed as a magnetic attraction member. During the operation of the air duct assembly 200, there is an electromagnet that is energized to control the blocking member to move to the conductive state position. When the air duct assembly 200 stops running, the electromagnet is powered off and loses its magnetic force. In the absence of external force, the blocking member will switch from the conductive state to the disconnected state under the action of gravity.

[0068] In other embodiments, the blocking member is suitable for switching from the on state to the off state under the action of the resetting force of the resetting member.

[0069] In some embodiments, the external force driving the blocking member to switch from the disconnected state to the connected state may be a driving force for the airflow.

[0070] Among them, when the direction in which the blocking piece moves from the disconnected state position to the conductive state position is in the same direction as the airflow direction, and the component of the force of the airflow acting on the blocking piece in the moving direction of the blocking piece is greater than the component of other forces acting on the blocking piece itself in the moving direction of the blocking piece, the blocking piece is suitable for switching from the disconnected state to the conductive state under the drive of the airflow.

[0071] When the air duct assembly 200 starts to run, that is, when the fan in the air duct assembly 200 starts to run, the airflow flows from the first air outlet 302 to the second air inlet 201, and drives the blocking member to switch from the disconnected state to the on state. During the operation of the air duct assembly 200, the force always acts on the blocking member until the air duct assembly 200 stops running and the blocking member loses the driving force of the airflow. The blocking member is suitable for switching from the on state to the disconnected state under the action of gravity or the reset force of the reset member.

[0072] Alternatively, the blocking member may be driven by using a controller and a motor to electrically control the blocking member to switch between an on state and an off state, which is not limited here.

[0073] Further, combined with Figure 2-Figure 8 In the illustrated embodiment, there is a flow port in the airflow channel 40 or at one end of the airflow channel 40, and the airflow flowing from the first air outlet 302 to the second air inlet 201 needs to flow into the air duct cavity 20 after passing through the flow port. Therefore, the blocking member can realize the switching between the on state and the off state by opening and closing the flow port.

[0074] In some embodiments, the blocking member may be a plate-like structure rotatably disposed in the airflow channel 40. The plate-like structure has a larger contact area with the airflow surface and a lighter weight, which is beneficial to airflow drive and can better seal the flow port.

[0075] Due to the limitations of the shape of the flow opening and the internal space of the airflow channel 40, in some embodiments, the blocking member cannot use a complete plate-like structure to close the entire flow opening, for example, when the flow opening is a circular opening. Therefore, the blocking member includes a rotatable first sealing plate 11 and a second sealing plate 12, and the first sealing plate 11 and the second sealing plate 12 are used to open and close different parts of the flow opening to ensure that the blocking member can completely close the flow opening, and the first sealing plate 11 and the second sealing plate 12 can both rotate to control the opening and closing of the flow opening.

[0076] Reference Figure 2-Figure 4 A weight-reducing recess 13 is provided on the first sealing plate 11 and / or the second sealing plate 12 to further reduce the weight of the first sealing plate 11 and / or the second sealing plate 12, so as to avoid the airflow driving force being unable to overcome the gravity of the first sealing plate 11 and / or the second sealing plate 12, resulting in the sealing member being unable to switch normally between the on state and the off state.

[0077] In some embodiments, the weight-reducing recess 13 is opened on the side of the first sealing plate 11 and / or the second sealing plate 12 facing away from the windward surface to avoid the opening of the weight-reducing recess 13 affecting the driving force of the airflow on the first sealing plate 11 and / or the second sealing plate 12.

[0078] like Figure 2-Figure 8As shown, the one-way valve 10 also includes: a mounting seat 2, which is fixed in the air flow channel 40 or at one end of the air flow channel 40 to provide a mounting position for the setting of the first sealing plate 11 and the second sealing plate 12, and the mounting seat 2 defines a flow port, and the first sealing plate 11 and the second sealing plate 12 are respectively rotatably arranged on one side of the mounting seat 2, specifically, the first sealing plate 11 and the second sealing plate 12 are respectively rotatably arranged on the side of the mounting seat 2 facing away from the incoming wind direction, so as to avoid the first sealing plate 11 and the second sealing plate 12 being restricted by the mounting seat 2 when they rotate to the position where the conduction state is located, and the mounting seat 2 is used to limit the position where the first sealing plate 11 and the second sealing plate 12 are in the disconnected state, so as to ensure that the first sealing plate 11 and the second sealing plate 12 can close the flow port, and ensure that the first sealing plate 11 and the second sealing plate 12 can stably control the opening and closing of the flow port.

[0079] Reference Figure 3-Figure 7 The flow port is a circular hole to cooperate with the air flow channel 40 with a circular cross section, to increase the area of ​​the flow port as much as possible, and to avoid the setting of the one-way valve 10 affecting the air flow rate.

[0080] like Figure 5 As shown, the mounting seat 2 includes a mounting ring 21, which defines a circular flow opening. Since the flow opening is a circular hole, the first sealing plate 11 and the second sealing plate 12 can be formed into semicircular sealing plates, and the positions of the rotating axes of the first sealing plate 11 and the second sealing plate 12 can be set at the center axis of the circular hole.

[0081] In some embodiments, the first sealing plate 11 and the second sealing plate 12 can use the same rotating shaft, and the first sealing plate 11 and the second sealing plate 12 are rotatably connected to the rotating shaft. In order for the first sealing plate 11 and the second sealing plate 12 to avoid each other, there is a gap between the first sealing plate 11 and the second sealing plate 12, which affects the sealing of the flow port.

[0082] In other embodiments, the first sealing plate 11 and the second sealing plate 12 can be rotatably disposed on the mounting seat 2 via a rotating shaft, and there is also a gap between the first sealing plate 11 and the second sealing plate 12 to affect the sealing performance of the flow port.

[0083] In order to ensure the sealing of the flow port and the stability of the first sealing plate 11 and the second sealing plate 12, as shown in FIG. Figure 5-Figure 7As shown, the mounting seat 2 also includes mounting ribs 22, which are arranged at the flow port and have both ends respectively connected to the mounting ring 21, and the mounting ribs 22 separate the flow port into a first air flow port 23 and a second air flow port 24, and the first sealing plate 11 is used to open and close the first air flow port 23, and the second sealing plate 12 is used to open and close the second air flow port 24. Therefore, the setting of the mounting ribs 22 can not only ensure the stability of the setting of the first sealing plate 11 and the second sealing plate 12, provide support for the rotating shafts of the first sealing plate 11 and the second sealing plate 12, but also close the gap between the first sealing plate 11 and the second sealing plate 12 to ensure the closedness of the flow port.

[0084] The first sealing plate 11 and the mounting seat 2 can be installed in such a manner that two first mounting protrusions 25 are provided on the side of the mounting ring 21 or the mounting rib 22 facing away from the incoming wind direction, the two first mounting protrusions 25 are arranged at intervals in the length direction of the mounting rib 22, one of the first sealing plate 11 and the first mounting protrusion 25 is provided with a first rotating shaft 111 and the other is provided with a first shaft hole 251 that cooperates with the first rotating shaft 111. In other words, the first rotating shaft 111 is fixedly provided on the first sealing plate 11, the two first mounting protrusions 25 are provided with first shaft holes 251 that are arranged opposite to each other, and the two ends of the first rotating shaft 111 are respectively rotatably matched with the two first shaft holes 251. Alternatively, the first rotating shaft 111 is provided between the two first mounting protrusions 25, the first sealing plate 11 is provided with a first shaft hole 251, and the first rotating shaft 111 passes through the first shaft hole 251, so that the first sealing plate 11 can rotatably cooperate with the first rotating shaft 111.

[0085] Furthermore, the second sealing plate 12 and the mounting seat 2 can be installed in such a manner that two second mounting protrusions 25 are provided on the side of the mounting ring 21 or the mounting rib 22 facing away from the incoming wind direction, the two second mounting protrusions 25 are arranged at intervals in the length direction of the mounting rib 22, one of the second sealing plate 12 and the second mounting protrusion 25 is provided with a second rotating shaft 121 and the other is provided with a second shaft hole 252 that cooperates with the second rotating shaft 121. In other words, the second sealing plate 12 is fixedly provided with the second rotating shaft 121, the two second mounting protrusions 25 are provided with second shaft holes 252 that are arranged opposite to each other, and the two ends of the second rotating shaft 121 are respectively rotatably matched with the two second shaft holes 252. Alternatively, the second rotating shaft 121 is provided between the two second mounting protrusions 25, the second sealing plate 12 is provided with a second shaft hole 252, and the second rotating shaft 121 passes through the second shaft hole 252, so that the second sealing plate 12 can rotatably cooperate with the second rotating shaft 121.

[0086] like Figure 3-Figure 7 As shown, the first mounting protrusion 25 and the second mounting protrusion 25 located on the same side are two separately arranged structures, or, as shown in the figure, the first mounting protrusion 25 and the second mounting protrusion 25 located on the same side are the same structure.

[0087] In some embodiments, the airflow direction at the flow port is upward, and the first sealing plate 11 and the second sealing plate 12 switch from the on state to the off state through the action of gravity. Therefore, the rotation angle of the first sealing plate 11 and the second sealing plate 12 should be less than 90 degrees to avoid the gravity of the sealing plates being unable to act on the driving state switching of the sealing plates, and the first sealing plate 11 and the second sealing plate 12 cannot switch from the on state to the off state.

[0088] Therefore, combined with Figure 5-Figure 8 In the illustrated embodiment, a limiting protrusion 26 is provided on the mounting seat 2 and / or the mounting rib 22. The limiting protrusion 26 is provided on the rotation path of the first sealing plate 11 and the second sealing plate 12, and is used to stop the first sealing plate 11 and the second sealing plate 12 to prevent the first sealing plate 11 and the second sealing plate 12 from rotating at an angle greater than or equal to 90 degrees.

[0089] Among them, when the first sealing plate 11 and the second sealing plate 12 are stopped by the limit protrusion 26, the first sealing plate 11 and the second sealing plate 12 are both inclined in the vertical direction. Therefore, when the first sealing plate 11 and the second sealing plate 12 lose the airflow driving force, the gravity of the first sealing plate 11 and the second sealing plate 12 themselves can drive them to rotate to the position of the disconnected state, ensuring that the first sealing plate 11 and the second sealing plate 12 can switch freely between the on state and the off state.

[0090] like Figure 8 As shown, the one-way valve 10 also includes a buffer 28. When the first sealing plate 11 and the second sealing plate 12 are in a state of closing the flow port, the buffer 28 is arranged between each of the first sealing plate 11 and the second sealing plate 12 and the mounting seat 2. On the one hand, the buffer 28 can reduce the reaction force generated by the first sealing plate 11 and the second sealing plate 12 contacting the mounting seat 2 after falling, thereby avoiding the first sealing plate 11 and the second sealing plate 12 from being damaged by force. On the other hand, the setting of the buffer 28 can eliminate the noise generated by the first sealing plate 11 and the second sealing plate 12 falling and contacting the mounting seat 2, thereby improving the user experience. On the other hand, the setting of the buffer 28 reduces the contact area between the first sealing plate 11 and the second sealing plate 12 and the mounting seat 2, thereby avoiding sticking between the mounting seat 2 and the first sealing plate 11 and the second sealing plate 12, thereby affecting the normal opening and closing of the first sealing plate 11 and the second sealing plate 12.

[0091] Among them, combined Figure 5-Figure 8 In the illustrated embodiment, a mounting groove 27 is provided on one side of the mounting seat 2 facing the first sealing plate 11 and the second sealing plate 12, and the buffer member 28 is at least partially disposed in the mounting groove 27 to ensure the stability of the buffer member 28 and provide sufficient space for the buffer member 28.

[0092] like Figure 2-Figure 8As shown, the clothing processing device also includes a connecting pipe 3, the two ends of which are respectively connected to the first air outlet 302 and the second air inlet 201, the connecting pipe 3 defines an air flow channel 40, and the mounting seat 2 can be arranged in the connecting pipe 3 or at the two ends of the connecting pipe 3.

[0093] Further, one end of the connecting pipe 3 has a connecting ring 31, and the connecting ring 31 is connected to the one-way valve 10. Specifically, in some embodiments, the connecting ring 31 is connected to the mounting seat 2, and the connecting ring 31 can stably cooperate with the outer ring of the mounting ring 21 of the mounting seat 2, so that the mounting seat 2 is stably set without affecting the sealing between the connecting pipe 3 and the air duct assembly 200 or the connecting pipe 3 and the clothes processing drum assembly 300.

[0094] Specific embodiments of the clothes treating device will be described below with reference to the accompanying drawings.

[0095] Reference Figure 1-Figure 8 The clothes processing device of the embodiment of the utility model comprises: a clothes processing drum assembly 300 , an air duct assembly 200 , a filter assembly 203 , a one-way valve 10 and a connecting pipe 3 .

[0096] The clothing processing drum assembly 300 defines a clothing processing chamber 30, and the clothing processing chamber 30 has a first air inlet 301 and a first air outlet 302. The air duct assembly 200 is arranged above the clothing processing drum assembly 300 and defines the air duct chamber 20. The air duct chamber 20 has a second air inlet 201 and a second air outlet 202. The first air outlet 302 is connected to the second air inlet 201 through a connecting pipe 3. The connecting pipe 3 extends vertically. The connecting pipe 3 has a connecting ring 31 at one end close to the second air inlet 201. The first air inlet 301 is connected to the second air outlet 202. The filter assembly 203 is at least partially arranged in the air duct chamber 20, and the filter assembly 203 is arranged close to the second air inlet 201, for filtering the airflow entering the air duct chamber 20 from the second air inlet 201.

[0097] The one-way valve 10 is arranged between the connecting ring 31 of the connecting pipe 3 and the air duct assembly 200. The one-way valve 10 includes: a mounting seat 2, a first sealing plate 11 and a second sealing plate 12. The mounting seat 2 includes a buffer member 28, a mounting ring 21 and a mounting rib 22. The mounting rib 22 is arranged at the flow port defined by the mounting ring 21 and the two ends are respectively connected to the mounting ring 21 to separate the flow port into a first air flow port 23 and a second air flow port 24. The first sealing plate 11 is used to open and close the first air flow port 23, and the second sealing plate 12 is used to open and close the second air flow port 24.

[0098] Two first mounting protrusions 25 are provided on the side of the mounting rib 22 facing away from the incoming wind direction. The two first mounting protrusions 25 are arranged at intervals in the length direction of the mounting rib 22. A first rotating shaft 111 is fixedly provided on the first sealing plate 11. Oppositely arranged first axial holes 251 are opened on the two first mounting protrusions 25. Both ends of the first rotating shaft 111 are rotatably matched with the two first axial holes 251 respectively, so that the first sealing plate 11 can be rotatably matched with the mounting base 2.

[0099] Two second mounting protrusions 25 are provided on the side of the mounting rib 22 facing away from the incoming wind direction. The two second mounting protrusions 25 are arranged at intervals in the length direction of the mounting rib 22. A second rotating shaft 121 is fixedly provided on the second sealing plate 12. Oppositely arranged second axial holes 252 are opened on the two second mounting protrusions 25. Both ends of the second rotating shaft 121 are rotatably matched with the two second axial holes 252 respectively, so that the second sealing plate 12 can be rotatably matched with the mounting base 2.

[0100] The first mounting protrusion 25 and the second mounting protrusion 25 located on the same side are of the same structure.

[0101] The airflow direction at the flow outlet is upward, and the mounting seat 2 is arranged in the horizontal direction. The first sealing plate 11 and the second sealing plate 12 are rotatably arranged above the mounting seat 2. When the first sealing plate 11 and the second sealing plate 12 are in a disconnected state, the first sealing plate 11 and the second sealing plate 12 are horizontally placed on the mounting seat 2 under the action of their own gravity. When the first sealing plate 11 and the second sealing plate 12 are in a disconnected state, the first sealing plate 11 and the second sealing plate 12 are horizontally placed on the mounting seat 2. When the first sealing plate 11 and the second sealing plate 12 are in a conducting state, both sides of the first sealing plate 11 and the second sealing plate 12 are tilted upward, and the angle between the first sealing plate 11 and the second sealing plate 12 and the horizontal direction is less than 90 degrees, so as to open the first airflow opening 23 and the second airflow opening 24.

[0102] Thus, the first sealing plate 11 and the second sealing plate 12 realize the switching of the first sealing plate 11 and the second sealing plate 12 from the on state to the off state through the action of their own gravity, and the external force driving the first sealing plate 11 and the second sealing plate 12 to switch from the off state to the on state can be the driving force of the airflow.

[0103] A limiting protrusion 26 is provided on the mounting rib 22 and the first mounting protrusion 25 / the second mounting protrusion 25. The limiting protrusion 26 stops the first sealing plate 11 and the second sealing plate 12 on the side facing away from the windward surface when the first sealing plate 11 and the second sealing plate 12 are in the on state, so as to ensure that the angle between the first sealing plate 11 and the second sealing plate 12 and the horizontal direction is less than 90 degrees when the first sealing plate 11 and the second sealing plate 12 are in the on state, so as to ensure that the first sealing plate 11 and the second sealing plate 12 can switch from the on state to the off state through the action of their own gravity.

[0104] The first sealing plate 11 and the second sealing plate 12 are provided with a weight-reducing recess 13 to further reduce the weight of the first sealing plate 11 and the second sealing plate 12, so as to avoid the airflow driving force being unable to overcome the gravity of the first sealing plate 11 and the second sealing plate 12, resulting in the sealing member being unable to switch normally between the on state and the off state.

[0105] The mounting seat 2 is provided with a mounting groove 27 on one side facing the first sealing plate 11 and the second sealing plate 12, and the buffer member 28 is at least partially arranged in the mounting groove 27. When the first sealing plate 11 and the second sealing plate 12 are in a state of closing the flow port, the buffer member 28 is arranged between each of the first sealing plate 11 and the second sealing plate 12 and the mounting seat 2. On the one hand, the buffer member 28 can reduce the reaction force generated by the first sealing plate 11 and the second sealing plate 12 contacting the mounting seat 2 after falling, thereby avoiding the first sealing plate 11 and the second sealing plate 12 being damaged by force. On the other hand, the setting of the buffer member 28 can eliminate the noise generated by the first sealing plate 11 and the second sealing plate 12 falling and contacting the mounting seat 2, thereby improving the user experience. On the other hand, the setting of the buffer member 28 reduces the contact area between the first sealing plate 11 and the second sealing plate 12 and the mounting seat 2, thereby avoiding sticking between the mounting seat 2 and the first sealing plate 11 and the second sealing plate 12, thereby affecting the normal opening and closing of the first sealing plate 11 and the second sealing plate 12.
