Description

Technical Field

[0001] The utility model relates to the technical field of air processing equipment, in particular to a valve component, a ventilation module and an air conditioner. Background Art

[0002] The ventilation module is used to process the indoor and outdoor air accordingly as needed. The ventilation module can have multiple working modes such as exhaust mode, dust removal mode and fresh air mode. In exhaust mode, the ventilation module discharges the indoor air to the outside. In dust removal mode, the ventilation module removes the dust on the filter and guides the dust-carrying airflow to the outside, and collects dust through the dust box during the process of exporting the dust to the outside. In fresh air mode, the ventilation module guides the outdoor air to the indoor. In the above multiple modes, the inlet and outlet of the airflow are different, and the airflow in each mode shares a cavity. Therefore, it is necessary to set a valve for each guide port, so as to open the corresponding guide port in different modes to achieve the corresponding function. However, when a valve is set for each guide port, each valve requires a drive motor or a drive structure to control the valve, which makes the ventilation module have too many parts and the cost is too high.

[0065] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0066] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0067] The ventilation module is used to process the indoor and outdoor air accordingly as needed. The ventilation module can have multiple working modes such as exhaust mode, dust removal mode and fresh air mode. In exhaust mode, the ventilation module discharges the indoor air to the outside. In dust removal mode, the ventilation module removes the dust on the filter and guides the dust-laden airflow to the outside. In the process of exporting the dust to the outside, the dust is collected through the dust box. In fresh air mode, the ventilation module guides outdoor air into the room. In the above multiple modes, the airflow inlet and outlet are different, and the airflow in each mode shares a cavity. Therefore, it is necessary to set a valve for each guide port, so as to open the corresponding guide port in different modes to achieve the corresponding function.

[0068] Specifically, the ventilation module may include an indoor air inlet (specifically, the first air guide port hereinafter), an indoor exhaust port, an outdoor exhaust port, and a dust removal port (specifically, the third air guide port hereinafter). In the exhaust mode, the airflow enters the ventilation module from the air inlet and is discharged to the outside from the outdoor exhaust port. The ventilation module also includes an air outlet (specifically, the second air guide port hereinafter) located inside the ventilation module and connected to the outdoor exhaust port. The airflow first flows through the above-mentioned air outlet and then flows through the outdoor exhaust port. In the dust removal mode, the dust on the filter screen is cleaned, and the air with dust enters the ventilation module from the dust removal port and is discharged to the outside from the outdoor exhaust port. In addition, in the process of guiding the dusty air to the outdoor exhaust port, it is first introduced into the dust box from the inlet of the dust box (specifically, the fourth air guide port hereinafter) and guided to the outdoor exhaust port after being filtered by the filter screen in the dust box. In the fresh air mode, the outdoor airflow is introduced into the ventilation module from the outdoor exhaust port and introduced into the room from the indoor exhaust port.

[0069] In exhaust mode, the first air guide port and the second air guide port need to be connected to each other, and the third air guide port and the fourth air guide port need to be closed to each other. In dust removal mode, the third air guide port and the fourth air guide port need to be connected to each other, and the first air guide port and the second air guide port need to be closed to each other. In fresh air mode, the first air guide port, the second air guide port, the third air guide port and the fourth air guide port need to be closed to each other. In the related art, either four valves are used to open and close the four air guide ports respectively to achieve the above functions (this solution requires four motors to drive the four valves respectively), or two components are used to work together to open and close the four air guide ports to achieve the above functions (this solution requires two motors to drive the four valves respectively). The above structures all require the provision of multiple drive motors, which results in a large number of parts in the ventilation module and a high material cost.

[0070] In view of this, see Figure 1-Figure 20The present application provides a valve assembly 100, which is used in a ventilation module 10. The ventilation module 10 is a device capable of gas exchange. The ventilation module 10 can have a ventilation mode, a dust removal mode, and a fresh air mode. Figure 8 The ventilation module 10 is provided with a first air guide port 210, a second air guide port 220, a third air guide port 230 and a fourth air guide port 240. The specific arrangement positions of the first air guide port 210, the second air guide port 220, the third air guide port 230 and the fourth air guide port 240 in the ventilation module 10 depend on actual needs. The first air guide port 210, the second air guide port 220, the third air guide port 230 and the fourth air guide port 240 are opened and closed respectively according to different modes of the ventilation module 10.

[0071] It should be noted that in different embodiments, the first air guide port 210, the second air guide port 220, the third air guide port 230 and the fourth air guide port 240 in different modes of the ventilation module 10 may have different arrangement positions and different opening and closing logics. For ease of description, the following embodiment exemplarily shows the opening and closing logic of one of the air guide ports. Specifically, see Figure 8-Figure 10 Under this opening and closing logic, in the ventilation mode of the ventilation module 10, the first air guide port 210 and the second air guide port 220 are connected to each other, and the third air guide port 230 and the fourth air guide port 240 are closed to each other; in the dust removal mode of the ventilation module 10, the third air guide port 230 and the fourth air guide port 240 are connected to each other, and the first air guide port 210 and the second air guide port 220 are closed to each other; in the fresh air mode of the ventilation module 10, the first air guide port 210, the second air guide port 220, the third air guide port 230 and the fourth air guide port 240 are all closed to each other.

[0072] See also Figure 1-6 as well as Figure 8 The valve assembly 100 includes a first component 110 and a second component 120. The first component 110 is configured to switch between a first position and a second position after being driven, that is, the first component 110 can be driven and move from the first position to the second position, or can be driven and move from the second position to the first position. In some embodiments, the first component 110 can also be driven and move to other positions, which will not be described in detail here. Figure 12-14 , the first component 110 can be translated along a straight line to switch between the first position and the second position, or the first component 110 can be translated along a curve to switch between the first position and the second position. Figure 8-Figure 10The first component 110 rotates around the axis to switch between the first position and the second position. The first component 110 has a first channel 112. The first channel 112 forms a first opening 1121 and a second opening 1122 on the outer wall of the first component 110. The airflow can enter and exit the first channel 112 through the first opening 1121 and / or the second opening 1122.

[0073] The driving method of the first component 110 depends on actual needs. In some embodiments, the first component 110 can be driven by the driving motor 130. In other embodiments, the first component 110 can be provided with a driving mechanism, and the user can manually rotate the first component 110 or manually push the first component 110 through the driving mechanism. In this embodiment, the first component 110 is configured to be driven by the driving motor 130. When the first component 110 is driven by the driving motor 130, the valve assembly 100 may include the driving motor 130 or may not include the driving motor 130 (in this case, the driving motor 130 may be a component of the ventilation module 10).

[0074] The second component 120 is configured to be driven by the first component 110 to the third position or the fourth position during the process of the first component 110 switching positions. In other embodiments, the second component 120 can also be driven by the first component 110 to other positions, which will not be described in detail here. Since the second component 120 is driven by the first component 110, when the first component 110 is driven by the driving motor 130, the second component 120 can be considered to be indirectly driven by the driving motor 130 driving the first component 110. And the first component 110 drives the second component 120 during the process of switching positions. Specifically, the first component 110 can drive the second component 120 during the process of moving from the first position to the second position, and the first component 110 can also drive the second component 120 during the process of moving from the second position to the first position. The first component 110 can also drive the second component 120 during the process of switching positions at other positions. The second component 120 has a second channel 122 . The second channel 122 and the outer wall of the second component 120 form a third opening 1221 and a fourth opening 1222 . Airflow can enter and exit the second channel 122 through the third opening 1221 and / or the fourth opening 1222 .

[0075] The driving method of the first component 110 driving the second component 120 depends on actual needs. In some embodiments, the driving relationship between the first component 110 and the second component 120 is fixed. For example, after the first component 110 moves from the first position to the second position, the first component 110 must drive the second component 120 from the third position to the fourth position. In other embodiments, the driving relationship between the first component 110 and the second component 120 is not fixed. For example, during the process of the first component 110 moving from the first position to the second position, the first component 110 may drive the second component 120 from the third position to the fourth position, or may not drive the second component 120. The specific driving method in this embodiment is described below.

[0076] See also Figure 1-Figure 6 as well as Figure 8-Figure 10 In some embodiments, since the first component 110 has two positions and the second component 120 has two positions, the first channel 112 of the first component 110 and the second channel 122 of the second component 120 may have different conduction modes when the first component 110 and the second component 120 are in different positions, and the different conduction modes of the first channel 112 and the second channel 122 may correspond to different states of the valve assembly 100. Specifically, the valve assembly 100 has a first state and a second state.

[0077] See also Figure 8 In the first state of the valve assembly 100, the first component 110 is driven to move to the first position, and the second component 120 is driven by the first component 110 to the third position, so that the first channel 112, the second channel 122, the first guide port 210 and the second guide port 220 are interconnected, and the valve assembly 100 is suitable for covering the third guide port 230 and the fourth guide port 240. The first state of the valve assembly 100 may correspond to one of the modes of the ventilation module 10. For example, in this embodiment, the state corresponding to the exhaust mode of the ventilation module 10 is taken as an example for description. When the ventilation module 10 is in exhaust mode, the first guide port 210 may be an indoor air inlet of the ventilation module 10, and the second guide port 220 may be an air outlet connected to the outdoor exhaust port 260 of the ventilation module 10. The airflow enters the ventilation module 10 from the first guide port 210, and after being connected by the valve assembly 100, the airflow is guided out of the ventilation module 10 through the second guide port 220 and the outdoor exhaust port 260 of the ventilation module 10. At this time, the valve assembly 100 connects the first guide port 210 and the second guide port 220, and closes the third guide port 230 and the fourth guide port 240 to prevent the airflow from flowing turbulently in the ventilation module 10.

[0078] See also Fig. 9In the second state of the valve assembly 100, the first component 110 is driven to move to the second position, and the second component 120 is driven to the fourth position by the first component 110, so that the first channel 112, the second channel 122, the third guide port 230 and the fourth guide port 240 are interconnected, and the valve assembly 100 is suitable for covering the first guide port 210 and the second guide port 220. The second state of the valve assembly 100 may correspond to another mode of the ventilation module 10. For example, in this embodiment, the dust removal mode of the ventilation module 10 corresponding to this state is taken as an example for description. When the ventilation module 10 is in the dust removal mode, the third guide port 230 may be the dust removal port of the ventilation module 10 (when the ventilation module 10 automatically removes dust, the air mixed with dust enters the ventilation module 10 from the dust removal port and is discharged to the outside), and the fourth guide port 240 may be the inlet of the dust collecting box 270, which is connected to the aforementioned outdoor exhaust port 260. The airflow enters the ventilation module 10 from the third guide port 230, and after being turned on by the valve assembly 100, it enters the dust collecting box 270 through the fourth guide port 240. The air mixed with dust is filtered by the filter screen of the dust collecting box 270, and then is guided out of the ventilation module 10 from the outdoor exhaust port 260 of the ventilation module 10. At this time, the valve assembly 100 connects the third guide port 230 and the fourth guide port 240, and closes the first guide port 210 and the second guide port 220, so as to prevent the airflow from flowing turbulently in the ventilation module 10 and prevent the air mixed with dust from being guided into the room from the first guide port 210.

[0079] In this embodiment, the valve assembly 100 is used in the ventilation module 10, and is used to perform corresponding opening and closing control on each guide port of the ventilation module 10 in at least two working modes of the ventilation module 10. Specifically, the first component 110 of the valve assembly 100 can be driven to switch positions between the first position and the second position, and in particular, the first component 110 can drive the second component 120 to switch positions between the third position and the fourth position during the position switching process. When the first component 110 is located at the first position and the second component 120 is located at the third position, the first component 110 and the second component 120 jointly conduct the first guide port 210 and the second guide port 220, and close the third guide port 230 and the fourth guide port 240. In the above state of the valve assembly 100, the ventilation module 10 can have the first working mode (the specific working mode depends on the specific arrangement position of each guide port). When the first component 110 is located at the second position and the second component 120 is located at the fourth position, the first component 110 and the second component 120 jointly conduct the third guide port 230 and the fourth guide port 240, and close the first guide port 210 and the second guide port 220. The valve assembly 100 in the above state can enable the ventilation module 10 to have a second working mode (the specific working mode depends on the specific arrangement position of each guide port). Since the second component 120 is driven by the first component 110, the valve assembly 100 in this embodiment only needs one drive motor 130 or one drive mechanism to be driven. Compared with the structure in the related art that uses two motors to drive the first component 110 and the second component 120 respectively, or uses four motors and four components to control the opening and closing of the four guide ports of the ventilation module 10, the number of drive components is reduced and the material cost is reduced.

[0080] In some embodiments, the valve assembly 100 can also adapt to the third mode of the ventilation module 10, specifically, see Fig.10The valve assembly 100 also has a third state. In the third state, the first component 110 is driven to move to the second position to cover the first guide port 210 and the second guide port 220, and the second component 120 is driven to move to the third position to cover the third guide port 230 and the fourth guide port 240. The third state of the valve assembly 100 can be adapted to the third mode of the ventilation module 10. For example, the third state of the valve assembly 100 can be adapted to the fresh air mode of the ventilation module 10. In this mode, the second guide port 220 and the fourth guide port 240 are both connected to the indoor exhaust port 250 of the ventilation module 10. Since the first guide port 210, the second guide port 220, the third guide port 230 and the fourth guide port 240 are all closed, the airflow can enter the ventilation module 10 from the outdoor exhaust port 260 and enter the room from the indoor exhaust port 250. The airflow will not be directed to the first guide port 210 and the third guide port 230, which is convenient for controlling the direction of the airflow. Moreover, in this embodiment, the valve assembly 100 can simultaneously realize the opening and closing switching of the guide port in the three states of the ventilation module 10, and the adaptability of the valve assembly 100 is higher; at the same time, during the switching process of the three states of the ventilation module 10, the valve assembly 100 can be driven by only one drive motor 130 or drive mechanism, thereby reducing the number of drive motors 130 or drive mechanisms and reducing the material cost of the ventilation module 10.

[0081] See also Fig.11 In other embodiments, in the third state of the valve assembly 100, the first component 110 and the second component 120 may have other arrangement positions. Specifically, in the third state, the first component 110 is driven to move to the first position to cover the third guide port 230 and the fourth guide port 240, and the second component 120 is driven to move to the fourth position to cover the first guide port 210 and the second guide port 220.

During the rotation of the first peripheral wall plate 111, the positions of the first opening 1121 and the second opening 1122 are switched, that is, when the first peripheral wall plate 111 rotates to the first position, the first opening 1121 and the second opening 1122 have a relative position with the first guide port 210 and the second guide port 220, and when the first peripheral wall plate 111 rotates to the second position, the first opening 1121 and the second opening 1122 have another relative position with the first guide port 210 and the second guide port 220. The internal structure of the first channel 112 depends on actual needs, and the first channel 112 can extend along a straight line or a curve. In this embodiment, the first channel 112 passes through the first peripheral wall plate 111 in a straight line to form a first opening 1121 and a second opening 1122. The first opening 1121 and the second opening 1122 can both be air inlets or air outlets. For ease of description, in this embodiment, the first opening 1121 is used as an air inlet and the second opening 1122 is used as an air outlet.

The second component 120 is configured to rotate around the axis of the second peripheral wall plate 121 after being driven (specifically driven by the first component 110). During the rotation of the second peripheral wall plate 121, the positions of the third opening 1221 and the fourth opening 1222 are switched, that is, when the second peripheral wall plate 121 rotates to the third position, the third opening 1221 and the fourth opening 1222 have a relative position with the first guide port 210 and the second guide port 220, and when the second peripheral wall plate 121 rotates to the fourth position, the third opening 1221 and the fourth opening 1222 have another relative position with the first guide port 210 and the second guide port 220. The internal structure of the second channel 122 depends on actual needs. The second channel 122 can extend along a straight line or a curve. In this embodiment, the second channel 122 passes through the second peripheral wall plate 121 along a straight line to form a third opening 1221 and a fourth opening 1222. The third opening 1221 and the fourth opening 1222 can both be air inlets or air outlets. For ease of description, in this embodiment, the third opening 1221 is used as an air inlet and the fourth opening 1222 is used as an air outlet. The second peripheral wall plate 121 can be mounted outside the first peripheral wall plate 111 or inserted into the first peripheral wall plate 111. See Figure 7In one embodiment, the second peripheral wall plate 121 is inserted into the first peripheral wall plate 111, that is, the second peripheral wall plate 121 is at least partially located in the first channel 112 and can rotate in the first channel 112. In one embodiment, the second peripheral wall plate 121 is sleeved outside the first peripheral wall plate 111, that is, the first peripheral wall plate 111 is at least partially located in the second channel 122 and can rotate in the second channel 122. The axis of the first peripheral wall plate 111 is parallel to or coincides with the axis of the second peripheral wall plate 121. The following description is based on the example that the second peripheral wall plate 121 is inserted into the first peripheral wall plate 111, and the axis of the first peripheral wall plate 111 coincides with the axis of the second peripheral wall plate 121.

In other embodiments, see Fig.11 In the third state of the valve assembly 100, the first peripheral wall plate 111 can be located at the first position and the second peripheral wall plate 121 can be located at the fourth position. At this time, the first peripheral wall plate 111 covers the third guide port 230 and the fourth guide port 240, and the second peripheral wall plate 121 covers the first guide port 210 and the second guide port 220. Figure 8-Figure 11 In each embodiment, since the first component 110 and the second component 120 are both switched by rotation, the driving is more convenient. At the same time, the first component 110 and the second component 120 are in a sleeve relationship, so that the opening and closing logic between the first opening 1121, the second opening 1122, the third opening 1221 and the fourth opening 1222 is easier to implement.

[0085] See also Figure 12-14 In other embodiments, the first component 110 and the second component 120 may also be in the form of plates, and the two components are stacked, and the first component 110 and the second component 120 are both translated along a straight line to switch positions. Fig.12 When the valve assembly 100 is in the first state, the first component 110 is in the first position, and the second component 120 is in the third position. At this time, the first channel 112 and the second channel 122 are connected, the first guide port 210 and the second guide port 220 are connected to each other, the third guide port 230 is closed by the first component 110, and the fourth guide port 240 is closed by the second component 120.

[0086] See also Figure 8-Figure 10 In some embodiments, the first opening 1121 and the second opening 1122 are distributed along the circumference of the first peripheral wall plate 111, so as to facilitate the position arrangement of the first guide port 210, the second guide port 220, the third guide port 230 and the fourth guide port 240. The first guide port 210, the third guide port 230, the second guide port 220 and the fourth guide port 240 can be arranged in sequence around the first peripheral wall plate 111, and there will be no position interference between the guide ports. Figure 8-Figure 10 In some embodiments, the third opening 1221 and the fourth opening 1222 are distributed along the circumference of the second peripheral wall plate 121, thereby further enhancing the adaptability of the positions of each guide port. In other embodiments, the first opening 1121 and the second opening 1122 can also be distributed along the axial direction of the first peripheral wall plate 111. In this case, the first guide port 210 and the third guide port 230 can be distributed along the axial direction of the first peripheral wall plate 111, the first guide port 210 and the second guide port 220 can be distributed along the circumference of the first peripheral wall plate 111, and the second guide port 220 and the fourth guide port 240 can be distributed along the circumference of the first peripheral wall plate 111.

[0087] See also Figure 8-Figure 10In some embodiments, the first opening 1121 and the second opening 1122 are symmetrically distributed about the axis of the first peripheral wall plate 111. In this solution, in one processing method of the first peripheral wall plate 111, the first opening 1121 and the second opening 1122 can be processed simultaneously by penetrating the first peripheral wall plate 111, so that the processing of the first opening 1121 and the second opening 1122 is more convenient; in another processing method of the first peripheral wall plate 111, the first peripheral wall plate 111 can be processed by an integral injection molding method. In this processing method, when the first opening 1121 and the second opening 1122 are symmetrically distributed, it is easier to demold the first peripheral wall plate 111. Similarly, the third opening 1221 and the fourth opening 1222 can also be symmetrically distributed about the axis of the second peripheral wall plate 121, so that the processing of the second peripheral wall plate 121 is more convenient.

[0088] See also Figure 7-10In some embodiments, the second peripheral wall plate 121 is inserted into the first peripheral wall plate 111. The first peripheral wall plate 111 includes a first curved plate 1111 and a second curved plate 1112 distributed along the circumferential direction. One side of the first curved plate 1111 and one side of the second curved plate 1112 jointly define a first opening 1121, and the other side of the first curved plate 1111 and the other side of the second curved plate 1112 jointly define a second opening 1122. When the first opening 1121 and the second opening 1122 are symmetrically distributed about the axis of the first peripheral wall plate 111, the first curved plate 1111 and the second curved plate 1112 are also symmetrically distributed about the axis of the first peripheral wall plate 111. In some embodiments, the first curved plate 1111 and the second curved plate 1112 may be spaced apart from each other at both ends along the circumference of the first peripheral wall plate 111, and the first opening 1121 and the second opening 1122 are gaps between the first curved plate 1111 and the second curved plate 1112. In this embodiment, the first curved plate 1111 and the second curved plate 1112 are connected to each other at both ends along the circumference of the first peripheral wall plate 111, and the first opening 1121 is provided at one of the intersections of the first curved plate 1111 and the second curved plate 1112, and the second opening 1122 is provided at another intersection of the first curved plate 1111 and the second curved plate 1112. Further, the first curved plate 1111 and the second curved plate 1112 may be provided integrally, thereby facilitating the processing of the first peripheral wall plate 111. In this embodiment, when the first component 110 is in the first position, the first curved plate 1111 is suitable for covering the third guide port 230, and the second curved plate 1112 is suitable for covering the fourth guide port 240. When the first component 110 is in the second position, the first curved plate 1111 is suitable for covering the first guide port 210, and the second curved plate 1112 is suitable for covering the second guide port 220. In other words, the first guide port 210, the third guide port 230, the second guide port 220 and the fourth guide port 240 can be distributed in sequence along the circumference of the first peripheral wall plate 111, and the first guide port 210 and the second guide port 220 are arranged relative to each other, and the third guide port 230 and the fourth guide port 240 are arranged relative to each other, so that the arrangement of each guide port is more compact, and the overall occupied space of the valve assembly 100 is reduced.

[0089] See also Figure 7-10In some embodiments, the second peripheral wall plate 121 includes a third curved plate 1211 and a fourth curved plate 1212 distributed along the circumferential direction, one side of the third curved plate 1211 and one side of the fourth curved plate 1212 jointly define a third opening 1221, and the other side of the third curved plate 1211 and the other side of the fourth curved plate 1212 jointly define a fourth opening 1222. When the third opening 1221 and the fourth opening 1222 are symmetrically distributed about the axis of the second peripheral wall plate 121, the third curved plate 1211 and the fourth curved plate 1212 are also symmetrically distributed about the axis of the second peripheral wall plate 121. In some embodiments, the third curved plate 1211 and the fourth curved plate 1212 may be spaced apart from each other at both ends along the circumferential direction of the second peripheral wall plate 121, and the third opening 1221 and the fourth opening 1222 are gaps between the third curved plate 1211 and the fourth curved plate 1212. In this embodiment, both ends of the third curved plate 1211 and the fourth curved plate 1212 along the circumference of the second peripheral wall plate 121 are connected to each other, and the third opening 1221 is provided at one of the intersections of the third curved plate 1211 and the fourth curved plate 1212, and the fourth opening 1222 is provided at the other intersection of the third curved plate 1211 and the fourth curved plate 1212. Further, the third curved plate 1211 and the fourth curved plate 1212 can be provided as a whole, so as to facilitate the processing of the second peripheral wall plate 121. In this embodiment, the structure of the second component 120 is more consistent with the structure of the first component 110, and it is more convenient for the first component 110 to drive the second component 120 to the corresponding position.

[0090] See also Figure 7-10 In some embodiments, in the third state of the valve assembly 100, the first arc plate 1111 covers the third opening 1221, the second arc plate 1112 covers the fourth opening 1222, the third arc plate 1211 covers the second opening 1122, and the fourth arc plate 1212 covers the first opening 1121. In addition, the first arc plate 1111 covers the first guide port 210, the second arc plate 1112 covers the second guide port 220, the third arc plate 1211 covers the third guide port 230, and the fourth arc plate 1212 covers the fourth guide port 240. In this solution, each arc plate is used to cover a guide port and an opening, which has a more compact structure and a better sealing effect. See Fig.11 In other embodiments, in the third state of the valve assembly 100, the first arc plate 1111 covers the fourth opening 1222, the second arc plate 1112 covers the third opening 1221, the third arc plate 1211 covers the second opening 1122, and the fourth arc plate 1212 covers the first opening 1121. In addition, the first arc plate 1111 covers the third guide port 230, the second arc plate 1112 covers the fourth guide port 240, the third arc plate 1211 covers the first guide port 210, and the fourth arc plate 1212 covers the second guide port 220.

[0091] In other embodiments, the ventilation module 10 may be provided with other guide ports along the circumference of the first peripheral wall plate 111. For example, the ventilation module 10 may be provided with a fifth guide port, and the first peripheral wall plate 111 of the valve assembly 100 may be driven to move to a position where the first channel 112 is connected to the fifth guide port and to a position where the fifth guide port is covered, thereby realizing the opening and closing of the fifth guide port. In order to match the number of guide ports, more than three openings may be provided on the first peripheral wall plate 111 and the second peripheral wall plate 121.

[0092] The two ends of the first peripheral wall plate 111 along its own axial direction can be closed or open. Whether the two ends of the first peripheral wall plate 111 along its own axial direction are closed or open depends on the processing cost and the sealing performance requirements. Figure 1-Figure 7 In some embodiments, the second peripheral wall plate 121 is inserted into the first peripheral wall plate 111. The first peripheral wall plate 111 has a first port 113 and a second port 114 that are arranged opposite to each other along its own axial direction, and the first component 110 also includes a first end plate 115 covering the first port 113. That is, one of the ports of the first peripheral wall plate 111 along its own axial direction is closed by the first end plate 115, thereby improving the sealing effect of the first peripheral wall plate 111, so that when the first channel 112 conducts airflow, the airflow will not overflow from the first port 113. The two ends of the second peripheral wall plate 121 along its own axial direction can be closed or open. Whether the two ends of the second peripheral wall plate 121 along its own axial direction are closed or open depends on the processing cost and the sealing performance requirements. See Figure 1-Figure 7 In some embodiments, the second peripheral wall plate 121 has a third port 123 and a fourth port 124 arranged opposite to each other along its own axial direction, the third port 123 is located on the side of the second peripheral wall plate 121 away from the first port 113, and the fourth port 124 is located on the side of the second peripheral wall plate 121 close to the first port 113, and the second component 120 further includes a second end plate 125 covering the third port 123. That is, one of the ports of the second peripheral wall plate 121 along its own axial direction is closed by the second end plate 125, thereby improving the sealing effect of the second peripheral wall plate 121, so that when the second channel 122 conducts airflow, the airflow will not overflow from the first port 113. In addition, the second end plate 125 can also form a certain seal on the second port 114, further reducing the amount of airflow overflowing in the first channel 112 when the first channel 112 is conducted.

[0093] When the second peripheral wall is inserted into the first peripheral wall, the fourth port 124 of the second peripheral wall can be covered by the inner wall of the first end plate 115, thereby forming a seal for the fourth port 124. In order to improve the sealing performance of the fourth port 124, see Figure 1-Figure 7In some embodiments, the second component 120 further includes a third end plate 126 covering the fourth port 124 .

[0094] The driving method between the first component 110 and the second component 120 depends on actual needs. In some embodiments, the first component 110 is provided with a driving structure 117, and the second component 120 is provided with a driven structure 127. Within the range of the driving structure 117 rotating along the circumferential direction of the first peripheral wall plate 111, the driving structure 117 can move to abut against the driven structure 127 and push the driven structure 127 to rotate along the circumferential direction of the first peripheral wall plate 111, so as to drive the second component 120 to rotate. The specific arrangement positions of the driving structure 117 and the driven structure 127 can be set accordingly according to actual needs. In some embodiments, see Figure 1-Figure 7 , a driven structure 127 is provided on the side of the third end plate 126 facing away from the second end plate 125, and a driving structure 117 is provided on the side of the first end plate 115 facing the third end plate 126. Within the travel of the driving structure 117 rotating along the circumferential direction of the first peripheral wall plate 111, the driving structure 117 can move to abut against the driven structure 127 and push the driven structure 127 to rotate along the circumferential direction of the first peripheral wall plate 111, so as to drive the second component 120 to rotate. That is, in this embodiment, the driving structure 117 and the driven structure 127 are arranged between the first end plate 115 and the third end plate 126. Compared with the structure in which the driving structure 117 and the driven structure 127 are arranged between the first peripheral wall plate 111 and the second peripheral wall plate 121, the radial occupied space of the first peripheral wall plate 111 and the second peripheral wall plate 121 can be reduced, thereby reducing the volume of the valve assembly 100. In other embodiments, the driving structure 117 and the driven structure 127 can also be arranged between the first peripheral wall plate 111 and the second peripheral wall plate 121. In this solution, the abutting position of the driving structure 117 and the driven structure 127 after abutting is located on the outer periphery of the second peripheral wall plate 121, so that the driving force generated by the driving structure 117 is greater and the driving efficiency of the driving structure 117 is higher.

[0095] The specific structures of the driving structure 117 and the driven structure 127 depend on actual needs. In some embodiments, see Figure 1-Figure 7 as well as Figure 18-Figure 20, the driving structure 117 is in the shape of a plate, and the radial dimension of the driving structure 117 along the first peripheral wall plate 111 may be less than or equal to the radius of the third end plate 126. The driving structure 117 is arranged along the radial direction of the first end plate 115. The driven structure 127 is in the shape of a plate, and the radial dimension of the driving structure 117 along the second peripheral wall plate 121 may be less than or equal to the radius of the third end plate 126. The driven structure 127 is arranged along the radial direction of the third end plate 126. When the first component 110 rotates along the first circumferential direction, the driving structure 117 can rotate to abut against one side of the driven structure 127, and during the subsequent rotation of the first component 110, the driving structure 117 can push the driven structure 127 to move along the first circumferential direction. When the driving structure 117 abuts against the driven structure 127 during the aforementioned driving process, if the first component 110 rotates along the second circumferential direction opposite to the first circumferential direction, the driving structure 117 separates from the driven structure 127, so that the driving structure 117 releases the driving of the driven structure 127. When the first component 110 continues to rotate along the second circumferential direction until the driving structure 117 abuts against the other side of the driven structure 127, the driving structure 117 can drive the driven structure 127 to rotate along the second circumferential direction when the first component 110 continues to rotate along the second circumferential direction. In other embodiments, the driving structure 117 can be a first magnet and the driven structure 127 can be a second magnet. The first magnet and the second magnet repel each other, so that when the first magnet rotates in a direction close to the second magnet, the second magnet can be pushed to rotate, and when the first magnet rotates in a direction away from the second magnet, the drive to the second magnet is canceled.

[0096] During the driving process of the driving motor 130 or the driving mechanism for the first component 110 and the second component 120, the driving motor 130 or the driving mechanism first drives the second component 120 to the corresponding position through the first component 110, and then drives the first component 110 to the corresponding position. Exemplarily, in the actual driving process, when the driving motor 130 drives the valve assembly 100 (when the valve assembly 100 does not include the driving motor 130) to move to the first state, the first component 110 needs to be driven to the first position, and the second component 120 needs to be driven to the third position. At this time, it is first determined whether the second component 120 is located in the third position. If the second component 120 is located in the third position, the driving motor 130 directly drives the first component 110 to be in the first position; if the second component 120 is not located in the third position, the driving motor 130 drives the first component 110 to rotate along the first circumferential direction, thereby indirectly driving the second component 120 to be located in the third position. After the second component 120 is located in the third position, the driving motor 130 drives the first component 110 to be located in the first position. If the first component 110 drives the second component 120 to be located in the third position and the first component 110 is already located in the first position, the driving motor 130 stops driving; if the first component 110 drives the second component 120 to be located in the third position and the first component 110 is not located in the first position, the driving motor 130 drives the first component 110 to rotate to the first position along a second circumferential direction opposite to the first circumferential direction.

[0097] In some embodiments, see Figure 1-Figure 7 as well as Figure 15-17 The first component 110 includes a first rotating shaft 116, which is connected to the side of the first end plate 115 away from the second port 114, and the second component 120 includes a second rotating shaft 128, which is connected to the side of the second end plate 125 away from the fourth port 124. The first rotating shaft 116 and the second rotating shaft 128 of the valve assembly 100 are respectively hinged to the shell body 200 of the ventilation module 10, so as to realize the positioning of the first component 110 and the second component 120. In this solution, the first component 110 is provided with a rotating shaft, that is, it is hinged to the shell body 200, and the second component 120 is provided with a rotating shaft, that is, it is hinged to the shell body 200. Compared with the structure in which both the first component 110 and the second component 120 are provided with two rotating shafts, there are fewer parts and a simpler structure; compared with the structure in which two rotating shafts are provided at both ends of the second component 120, the two rotating shafts are passed through the two ends of the first peripheral wall plate 111, and the first component 110 is positioned on the second component 120, in this solution, the first component 110 and the second component 120 are both positioned on the shell body 200 of the ventilation module 10 by using rotating shafts, and the positioning effect is better.

[0098] The driven part of the first component 110 depends on actual needs. In some embodiments, the first component 110 obtains driving force by using the first rotating shaft 116. Specifically, the first rotating shaft 116 can pass through the shell body 200 of the ventilation module 10, and the part where the first rotating shaft 116 passes through the shell body 200 is used to obtain driving force. In some embodiments, a rotating dial is provided at the part where the first rotating shaft 116 passes through the shell body 200. The user can manually turn the rotating dial from the outside to drive the first component 110 to rotate, that is, the driving force in this embodiment comes from the user. In other embodiments, see Figure 1-Figure 7 as well as Figure 15-17 The driving force comes from the driving motor 130. Specifically, the valve assembly 100 further includes the driving motor 130, which is connected to the first component 110 and is used to drive the first component 110 to switch between the first position and the second position. The driving motor 130 can be connected to the first rotating shaft 116 of the first component 110, and the first rotating shaft 116 is driven by the driving motor 130 to drive the first component 110 and the second component 120 to rotate.

[0099] In addition to the first rotating shaft 116 of the first component 110 being able to obtain driving force, in other embodiments, the first peripheral wall plate 111 of the first component 110 can obtain driving force. Exemplarily, the outer peripheral wall outside the first peripheral wall plate 111 can be provided with external teeth, and the ventilation module 10 is provided with a gear assembly, which meshes with the external teeth outside the first peripheral wall plate 111. The gear assembly includes an input shaft, which passes through the shell body 200 of the ventilation module 10. The user can manually rotate the input shaft to drive the first component 110 to rotate, or the driving motor 130 of the valve assembly 100 drives the input shaft to drive the first component 110 to rotate.

[0100] In order to improve the sealing effect of the first component 110 and the second component 120, in some embodiments, the outer wall of the first peripheral wall plate 111 is provided with a sealing layer, and the material of the sealing layer includes rubber, silicone or felt. After the outer wall of the first peripheral wall plate 111 is provided with a sealing layer, when the first peripheral wall plate 111 is located in the first position, the first peripheral wall plate 111 has a better sealing effect on the third guide port 230 and the fourth guide port 240; when the first peripheral wall plate 111 is located in the second position, the first peripheral wall plate 111 has a better sealing effect on the first guide port 210 and the second guide port 220. In some embodiments, the outer wall of the second peripheral wall plate 121 is provided with a sealing layer, and the material of the sealing layer includes rubber, silicone or felt. After the outer wall of the second peripheral wall plate 121 is provided with a sealing layer, when the second peripheral wall plate 121 is located at the third position and the first peripheral wall plate 111 is located at the second position, the second peripheral wall plate 121 has a better sealing effect on the third guide port 230 and the fourth guide port 240, and a better sealing effect on the first opening 1121 and the second opening 1122; when the second peripheral wall plate 121 is located at the fourth position and the first peripheral wall plate 111 is located at the first position, the second peripheral wall plate 121 has a better sealing effect on the first guide port 210 and the second guide port 220, and a better sealing effect on the first opening 1121 and the second opening 1122. In addition, when the first peripheral wall plate 111 is located at the first position and the second peripheral wall plate 121 is located at the third position, and when the first peripheral wall plate 111 is located at the second position and the second peripheral wall plate 121 is located at the fourth position, the sealing effect of the gap between the first peripheral wall plate 111 and the second peripheral wall plate 121 is better.

The first guide port 210, the second guide port 220, the third guide port 230 and the fourth guide port 240 can be any four guide ports in the shell body 200 for conducting airflow and are simultaneously opened and closed by the valve assembly 100. In this embodiment, the first guide port 210 is the indoor air inlet of the ventilation module 10, the second guide port 220 is the air outlet connected to the outdoor exhaust port 260, the third guide port 230 is the dust removal port, and the fourth guide port 240 is the entrance of the dust box 270 connected to the indoor exhaust port 250. In view of the improvement of the valve assembly 100, the ventilation module 10 in this embodiment has the technical effects of the valve assembly 100 in any of the aforementioned embodiments, which will not be elaborated here.

[0102] See also Figure 8-Figure 11 as well as Figure 15-17In some embodiments, the shell body 200 further includes an outlet for guiding out air (specifically, the indoor exhaust port 250 and / or the outdoor exhaust port 260 mentioned above), and the ventilation module 10 further includes a dust box 270 disposed in the shell body 200. The first air guide port 210 is suitable for introducing air into the shell body 200, the second air guide port 220 is connected to the outlet, the third air guide port 230 is suitable for introducing dust into the shell body 200, and the fourth air guide port 240 is connected to the inlet of the dust box 270. A filter net may be provided in the dust box 270, and the filter net is used to filter dust, so that dust in the air mixed with dust is not easy to pass through the dust box 270, thereby protecting the internal components of the ventilation module 10 and preventing dust from accumulating on the internal components of the ventilation module 10, thereby affecting the operation of the internal components.

[0103] In order to drive the second component 120 to the third position and the fourth position more accurately, referring to the figure, in some embodiments, the second component 120 includes a second rotating shaft 128, the shell body 200 includes a positioning hole 280, the second rotating shaft 128 is penetrated by the positioning hole 280, and the second rotating shaft 128 includes a first elastic column 1281 and a second elastic column 1282 arranged relatively in a direction perpendicular to its own axis. The first elastic column 1281 can elastically move in a direction close to or away from the second elastic column 1282, and the second elastic column 1282 can elastically move in a direction close to or away from the first elastic column 1281, so that the distance between the first elastic column 1281 and the second elastic column 1282 can be reduced or enlarged. The positioning hole 280 includes four positioning recesses 281 distributed along the circumference of the second rotating shaft 128, and the first elastic column 1281 and the second elastic column 1282 can be positioned in two opposite positioning recesses 281 one by one. For example, along the circumference of the second rotating shaft 128, the four positioning recesses 281 are named as the first positioning recess, the second positioning recess, the third positioning recess and the fourth positioning recess respectively. When the first elastic column 1281 is positioned in the first positioning recess, the second elastic column 1282 is positioned in the third positioning recess; when the first elastic column 1281 rotates to be positioned in the second positioning recess, the second elastic column 1282 rotates together to be positioned in the fourth positioning recess. That is, the second rotating shaft 128 has four stable positioning positions in the positioning hole 280, and the four stable positioning positions include the third position and the fourth position. The following definition of "stable positioning position" is made as follows: the second component 120 cannot spontaneously escape from the target positioning position under the premise of not being driven by the first component 110, and when the second component 120 is driven by the first component 110 to a positioning position within a preset range beside the target positioning position, after the driving force is withdrawn, the second component 120 will spontaneously return to the target positioning position, and the target positioning position is called a stable positioning position.
