Abstract
Description
Technical Field
[0001] This application relates to the field of waterproof and breathable valve technology, and in particular to a waterproof and breathable valve and electronic device. Background Technology
[0002] Currently, most electronic devices use waterproof vent valves to balance the internal and external air pressure, preventing moisture from entering and damaging the device. However, research has found that even with waterproof vent valves, water molecules can still enter the device after prolonged use. These water molecules tend to accumulate on highly hygroscopic components. When the device is running, the heat generated by these components causes the accumulated water molecules to evaporate into steam. Since the steam temperature is higher than the ambient temperature, condensation can easily form on the device's casing, affecting its performance. Summary of the Invention
[0003] This application provides a waterproof and breathable valve and an electronic device to solve the problem in related technologies where water molecules accumulate inside electronic devices, causing condensation during use and affecting the performance of the electronic devices.
[0004] In a first aspect, this application provides a waterproof and breathable valve, comprising:
[0005] A first housing has a gas passage having a first port and a second port opposite to each other;
[0006] A waterproof and breathable membrane is located at the first port of the first housing;
[0007] The moisture-absorbing component is located within the gas channel;
[0008] An adjustment component, at least partially located within the gas channel, has a first state and a second state. In the first state, the adjustment component blocks the communication between the first port and the second port, thereby dividing the gas channel into a first sub-channel near the first port and a second sub-channel near the second port. The moisture-absorbing component is located in the first sub-channel and / or oriented towards the first port, allowing the moisture-absorbing component to expel moisture via the waterproof and breathable membrane at the first port. In the second state, the first port is connected to the second port via the gas channel, allowing the moisture-absorbing component to absorb water molecules within the gas channel and to balance the internal and external air pressure of the gas channel via the waterproof and breathable membrane.
[0009] Secondly, this application provides an electronic device, comprising:
[0010] The second housing has a receiving cavity and an opening communicating with the receiving cavity;
[0011] The aforementioned waterproof and breathable valve is disposed at the opening of the second housing, and the second port of the waterproof and breathable valve is connected to the receiving cavity.
[0012] The waterproof and breathable valve and electronic device of this application, by incorporating a moisture-absorbing component, allow water molecules inside the first housing and the electronic device to accumulate on the moisture-absorbing component, reducing the water molecule content in the electronic device and ensuring its performance. By incorporating an adjustment component with a first state and a second state, when the adjustment component is in the first state, the moisture-absorbing component can release the absorbed water molecules through the waterproof and breathable membrane at the first port. When the adjustment component is in the second state, the first port is connected to the second port via a gas channel. In this state, the waterproof and breathable membrane can balance the internal and external pressure, and the moisture-absorbing component can effectively absorb water molecules inside the first housing and the electronic device.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0028] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0029] This application provides a waterproof and breathable valve 100. Please refer to... Figure 1 The waterproof and breathable valve 100 includes a first housing 110 and a waterproof and breathable membrane 120. The first housing 110 has a gas channel 111, which has a first port 1111 and a second port 1112. The waterproof and breathable membrane 120 can be connected to the first port 1111 of the first housing 110.
[0030] The waterproof and breathable membrane 120 has a dense microporous structure; for example, the pore size of the waterproof and breathable membrane 120 can be greater than or equal to 0.1 μm and less than or equal to 10 μm. Since air molecules have a diameter of only 0.0004 μm, they can freely pass through the waterproof and breathable membrane 120, while water molecules have a diameter of approximately 400 μm, which is much larger than the pore size of the waterproof and breathable membrane 120, and will be obstructed by the membrane. Thus, the waterproof and breathable valve 100 can compensate for gas pressure while ensuring liquid sealing, achieving pressure balance inside and outside the gas channel 111.
[0031] It should be noted that even though the pore size of the waterproof and breathable membrane 120 is much smaller than the diameter of water molecules, research has found that after long-term use, some water molecules will still permeate through the waterproof and breathable membrane 120 and enter the gas channel 111 of the first housing 110. Thus, when the waterproof and breathable valve 100 is used in electronic devices, the water molecules entering through the waterproof and breathable membrane 120 will further enter the electronic device and accumulate on highly hygroscopic components. When the electronic device is running, the heat generated by the components causes the accumulated water molecules to evaporate into steam. Since the steam temperature is higher than the ambient temperature, condensation easily forms on the housing of the electronic device, affecting its performance. To solve this problem, the waterproof and breathable valve 100 of this embodiment may further include a moisture-absorbing component 130 located within the gas channel 111 for absorbing water molecules. The moisture-absorbing component 130 can be made of a highly hygroscopic material so that water molecules inside the first housing 110 and the electronic device can accumulate on the moisture-absorbing component 130 for centralized treatment.
[0032] Optionally, the waterproof and breathable valve 100 may further include an adjusting component 140 located at least partially within the gas channel 111. Specifically, the adjusting component 140 may have a first state and a second state. In the first state, the adjusting component 140 can block the connection between the first port 1111 and the second port 1112 of the gas channel 111. In the second state, the first port 1111 can be connected to the second port 1112 via the gas channel 111. The adjusting component 140 blocking the connection between the first port 1111 and the second port 1112 can be considered as the gas channel 111 being divided into two independent sub-channels by the adjusting component 140. For example, the gas channel 111 may be divided by the adjusting component 140 into a first sub-channel 1113 near the first port 1111 and a second sub-channel 1114 near the second port 1112. Thus, when the regulating component 140 is in the first state, the moisture-absorbing component 130 can be located within the first sub-channel 1113 and / or positioned towards the first port 1111, so that the moisture-absorbing component 130 can release the absorbed water molecules through the waterproof and breathable membrane 120 at the first port 1111. For example, the absorbed water molecules can be evaporated by heating and released through the waterproof and breathable membrane 120, as will be described in more detail below. When the regulating component 140 is in the second state, please refer to... Figure 2 The first port 1111 is connected to the second port 1112 via the gas channel 111. At this time, the waterproof and breathable membrane 120 can balance the internal and external pressure, and the moisture absorption component 130 can absorb water molecules inside the first housing 110 and the electronic device.
[0033] In one exemplary solution, see [reference] Figure 1 and Figure 2 The moisture-absorbing component 130 can be installed on the adjusting component 140, so that when the adjusting component 140 switches between the first and second states, the moisture-absorbing component 130 can switch positions under the action of the adjusting component 140, thereby achieving moisture removal and absorption. In another exemplary embodiment, see [reference needed]. Figure 3 and Figure 4 The moisture-absorbing component 130 can be installed on the first housing 110 and located in the first sub-channel 1113. Thus, when the adjusting component 140 is in the first state, the moisture-absorbing component 130 can expel moisture, and when the adjusting component 140 is in the second state, the moisture-absorbing component 130 can absorb moisture.
[0034] In one exemplary solution, see [reference] Figure 4The adjustment assembly 140 may include an adjustment member 141, which can be directly and movably connected to the first housing 110 to achieve switching between a first state and a second state. For example, one end of the adjustment member 141 can be rotatably connected to the first housing 110. The adjustment member 141 can be designed as an integral elastic structure, or only its outer periphery can be designed as an elastic structure to allow the adjustment member 141 to rotate smoothly within the first housing 110.
[0035] In another exemplary solution, see [reference] Figure 5 The adjustment component 140 may include an adjustment member 141 and a mounting member 142. The mounting member 142 may be located inside the gas channel 111 and connected to the first housing 110. The mounting member 142 may divide the gas channel 111 into a first sub-channel 1113 and a second sub-channel 1114. The mounting member 142 may be provided with a through hole 1421 that connects the first sub-channel 1113 and the second sub-channel 1114. In the first state, the adjustment member 141 may close the through hole 1421 to block the connection between the first port 1111 and the second port 1112. In the second state, the adjustment member 141 may open the through hole 1421 to connect the first port 1111 and the second port 1112. The adjustment assembly 140 is designed to include an adjustment member 141 and a mounting member 142, and the on / off adjustment of the gas channel 111 is converted into the on / off adjustment of the through hole 1421 on the mounting member 142 within the gas channel 111. Since the diameter of the through hole 1421 is reduced compared to the diameter of the gas channel 111, the structure of the adjustment member 141 can be made smaller, so that the adjustment member 141 will not contact the inner wall surface of the gas channel 111 when switching between the first state and the second state, and will not be obstructed by the inner wall surface of the gas channel 111, which facilitates the smooth movement of the adjustment member 141.
[0036] Further optionally, in one exemplary embodiment, the adjusting member 141 can open and close the through hole 1421 by rotation. For example, the adjusting member 141 can be rotatably connected to the mounting member 142 or the first housing 110. In another exemplary embodiment, the adjusting member 141 can also open and close the through hole 1421 by translation. For example, the adjusting member 141 can be slidably connected to the mounting member 142 or the first housing 110. Specifically, the adjusting member 141 can be slidably connected to the first housing 110 and can move along the axis of the through hole 1421; or, the adjusting member 141 can be slidably connected to the mounting member 142 and can move along a direction perpendicular to the axis of the through hole 1421. The embodiments of this application do not limit the movement mode and connection mode of the adjusting member 141.
[0037] Specifically, when the adjusting member 141 opens and closes the through hole 1421 by rotation, in one exemplary embodiment, the adjusting member 141 may include a first rotating plate 1411. The first rotating plate 1411 may be located on the side of the mounting member 142 near the second port 1112 and rotatably connected to the mounting member 142. In a first state, the first rotating plate 1411 closes the through hole 1421, and in a second state, the first rotating plate 1411 opens the through hole 1421. At this time, the moisture-absorbing component 130 may be disposed on the surface of the first rotating plate 1411 facing the mounting member 142 or within the first sub-channel 1113. Designing the adjusting member 141 to include a single rotating plate results in a simple structure and convenient assembly, allowing for flexible adjustment according to specific usage requirements during actual assembly.
[0038] It should be noted that the adjustment component 140 can also have a third state. In the third state, the adjustment component 140 can block the connection between the first port 1111 and the second port 1112, and the moisture-absorbing component 130 is located in the second sub-channel 1114 and / or facing the second port 1112. When the adjustment component 140 is in the third state, the moisture-absorbing component 130 is located in the second sub-channel 1114 and / or facing the second port 1112, which allows water molecules inside the first housing 110 and the electronic device to quickly gather on the highly hygroscopic moisture-absorbing component 130, thereby accelerating the removal rate of water molecules from the first housing 110 and the devices inside the electronic device.
[0039] When the adjusting member 141 opens and closes the through hole 1421 by rotation, and the adjusting assembly 140 has a first state, a second state, and a third state, please refer to [the relevant documentation]. Figure 6 The adjusting member 141 may include a first rotating plate 1411 and a second rotating plate 1412 connected to the first rotating plate 1411. The first rotating plate 1411 may be located on the side of the mounting member 142 near the second port 1112, and the second rotating plate 1412 may be located on the side of the mounting member 142 near the first port 1111. A moisture-absorbing component 130 may be provided on the surface of the first rotating plate 1411 facing the mounting member 142 and / or the surface of the second rotating plate 1412 facing the mounting member 142. The first rotating plate 1411 and / or the second rotating plate 1412 may be rotatably connected to the mounting member 142 so that in a first state, the first rotating plate 1411 closes the through hole 1421. (See reference...) Figure 7 In the second state, both the first rotating plate 1411 and the second rotating plate 1412 have through holes 1421 open, as can be seen in the reference. Figure 6 In the third state, the second rotating plate 1412 closes the through hole 1421, as can be seen in the following reference. Figure 8The adjusting component 141 is designed to include a first rotating plate 1411 and a second rotating plate 1412 located on both sides of the mounting component 142, such that the adjusting component 140 has a first state in which the first rotating plate 1411 closes the through hole 1421 and a third state in which the second rotating plate 1412 closes the through hole 1421. When the adjusting component 140 is in the third state, the first port 1111 and the second port 1112 are disconnected and the moisture-absorbing component 130 is oriented towards the second port 1112. At this time, the waterproof and breathable valve 100 is mainly used to absorb water molecules in the electronic device through the moisture-absorbing component 130. Compared with the adjusting component 140 absorbing water molecules in the electronic device through the moisture-absorbing component 130 when it is in the second state, the water absorption efficiency is higher.
[0040] It should be noted that you should refer to [link / reference]. Figure 7 In the first state, the first rotating plate 1411 closing the through hole 1421 can be achieved by the following: the surface of the first rotating plate 1411 facing the mounting member 142 is in contact with the surface of the mounting member 142 facing the first rotating plate 1411, and the first rotating plate 1411 covers the through hole 1421. For details, please refer to... Figure 7 and Figure 9 The first rotating plate 1411 may include a first part 1413 corresponding to the through hole 1421 and a second part 1414 surrounding the first part 1413. In the first state, the first part 1413 is used to close the through hole 1421.
[0041] To improve the sealing performance of the first rotating plate 1411 when closing the through hole 1421, a first sealing element 143 may be provided on the surface of the first rotating plate 1411 facing the mounting member 142 and / or the surface of the mounting member 142 facing the first rotating plate 1411. This allows the first rotating plate 1411 and the mounting member 142 to compress the first sealing element 143 when the first rotating plate 1411 closes the through hole 1421, thereby improving the sealing effect of the adjusting assembly 140. Optionally, the first sealing element 143 may be generally annular. When the first sealing element 143 is provided on the first rotating plate 1411, it may be located on the second portion 1414 of the first rotating plate 1411. When the first sealing element 143 is provided on the mounting member 142, it may be arranged around the periphery of the through hole 1421.
[0042] Similarly, please refer to Figure 8 In the third state, the second rotating plate 1412 can close the through hole 1421 by having the surface of the second rotating plate 1412 facing the mounting member 142 adhere to the surface of the mounting member 142 facing the second rotating plate 1412, and the second rotating plate 1412 covering the through hole 1421. For details, please refer to... Figure 8 and Figure 10The second rotating plate 1412 may include a third part 1415 corresponding to the through hole 1421 and a fourth part 1416 surrounding the third part 1415. In the first state, the third part 1415 is used to close the through hole 1421.
[0043] To improve the sealing performance of the second rotating plate 1412 when closing the through hole 1421, a second sealing element 144 may be provided on the surface of the second rotating plate 1412 facing the mounting member 142 and / or the surface of the mounting member 142 facing the second rotating plate 1412. This allows the second rotating plate 1412 and the mounting member 142 to compress the second sealing element 144 when the second rotating plate 1412 closes the through hole 1421, thereby improving the sealing effect of the adjusting assembly 140. Optionally, the second sealing element 144 may be generally annular. When the second sealing element 144 is provided on the second rotating plate 1412, it may be located in the fourth portion 1416 of the second rotating plate 1412. When the second sealing element 144 is provided on the mounting member 142, it may be arranged around the periphery of the through hole 1421.
[0044] Please see Figure 9 and Figure 10 The moisture-absorbing assembly 130 may include a first moisture-absorbing portion 131 mounted on the surface of the first rotating plate 1411 facing the mounting member 142; and / or, the moisture-absorbing assembly 130 may include a second moisture-absorbing portion 132 mounted on the surface of the second rotating plate 1412 facing the mounting member 142. The first moisture-absorbing portion 131 may correspond to the first portion 1413 of the first rotating plate 1411, and the second moisture-absorbing portion 132 may correspond to the third portion 1415 of the second rotating plate 1412. Preferably, the moisture-absorbing assembly 130 includes both the first moisture-absorbing portion 131 and the second moisture-absorbing portion 132 to increase the design area of the moisture-absorbing portion and improve the moisture-absorbing performance of the moisture-absorbing assembly 130. The moisture-absorbing assembly 130 may use a desiccant, desiccant, etc., and this embodiment does not limit the choice of desiccant.
[0045] The first rotating plate 1411 and the mounting part 142 can be rotatably connected as follows: (See reference) Figure 11 One of the first rotating plate 1411 and the mounting component 142 is provided with a first rotating shaft 1451, and the other of the first rotating plate 1411 and the mounting component 142 is provided with a first rotating groove 1452. The first rotating shaft 1451 is located in the first rotating groove 1452 and can rotate within the first rotating groove 1452. The rotational connection between the first rotating plate 1411 and the mounting component 142 is achieved by the relative rotation of the first rotating shaft 1451 and the first rotating groove 1452. The connection method is simple and easy to manufacture.
[0046] Optionally, to improve the connection stability between the first rotating plate 1411 and the mounting member 142, a first mounting groove 1453 communicating with the first rotating groove 1452 may be provided on one of the first rotating grooves 1452, and a first mounting part 1454 connected to the first rotating shaft 1451 may be provided on one of the first rotating shafts 1451. The first mounting part 1454 may be located in the first mounting groove 1453.
[0047] For example, a first mounting groove 1453 may be provided on the surface of the mounting member 142 facing the first rotating plate 1411. A first rotating groove 1452 communicating with the first mounting groove 1453 may be provided on the inner sidewall of the first mounting groove 1453. A first mounting part 1454 located in the first mounting groove 1453 and a first rotating shaft 1451 located in the first rotating groove 1452 may be provided on the first rotating plate 1411. By providing the first mounting groove 1453 on the mounting member 142 and the first rotating groove 1452 being provided on the inner sidewall of the first mounting groove 1453, the structural design of the first rotating groove 1452 is more concealed and less prone to damage; and the connection reliability between the first rotating plate 1411 and the mounting member 142 can be improved.
[0048] The number of first rotating shafts 1451 can be one or more. Preferably, there can be two first rotating shafts 1451, which are spaced apart. The number of first rotating slots 1452 can be equal to the number of first rotating shafts 1451, and each first rotating shaft 1451 is located in one first rotating slot 1452. By setting two first rotating shafts 1451 and two first rotating slots 1452, the manufacturing cost can be reduced while improving the connection stability between the mounting component 142 and the first rotating plate 1411.
[0049] It should be noted that when there are two first rotating shafts 1451, both first rotating shafts 1451 can be simultaneously disposed on the first rotating plate 1411, or simultaneously disposed on the mounting member 142, or one rotating shaft can be disposed on the first rotating plate 1411 and the other on the mounting member 142. This embodiment of the application does not limit this. When there are two first rotating shafts 1451, the number of first mounting parts 1454 and the number of first mounting slots 1453 can both be two. Each first rotating shaft 1451 can be connected to one first mounting part 1454, and each first mounting part 1454 can be located within one first mounting slot 1453.
[0050] Similarly, the rotational connection between the second rotating plate 1412 and the mounting component 142 can be the same as the connection between the first rotating plate 1411 and the mounting component 142. For example, the rotational connection can be achieved through the second rotating shaft and the second rotating groove. This embodiment of the application will not elaborate further on this.
[0051] Optionally, please refer to [the relevant document / reference]. Figures 7 to 10 The adjusting member 141 may also include a connecting structure 146. One end of the connecting structure 146 can be connected to the first rotating plate 1411, and the other end of the connecting structure 146 can pass through the through hole 1421 and connect to the second rotating plate 1412. Designing the connecting structure 146 that connects the first rotating plate 1411 and the second rotating plate 1412 to pass through the through hole 1421 to achieve the connection between the two can reduce or even avoid friction between the connecting structure 146 and the mounting member 142 during the rotation of the adjusting member 141, thus ensuring the smooth operation of the adjusting member 141.
[0052] Optionally, at least one of the first rotating plate 1411 and the second rotating plate 1412 may be detachably connected to the connecting structure 146. In this way, when assembling the adjusting member 141 with the mounting member 142, the connection between one of the first rotating plate 1411 and the connecting structure 146 can be first disconnected, allowing the connecting structure 146 to pass through the through hole 1421 before assembling the adjusting member 141, thus improving assembly efficiency.
[0053] Please see Figure 12 The waterproof and breathable valve 100 may further include a drive member 150 for driving the adjusting member 141 to rotate relative to the mounting member 142. This enables the adjusting member 141 to switch between a first state and a second state under the action of the drive member 150, or to switch between a first state, a second state, and a third state under the action of the drive member 150, thus achieving intelligent switching.
[0054] Optionally, the driving component 150 may include a first motor, and the output shaft of the first motor is connected to the first rotating plate 1411 to drive the first rotating plate 1411 to rotate relative to the mounting component 142. Optionally, the driving component 150 may include a second motor, and the output shaft of the second motor is connected to the second rotating plate 1412 to drive the second rotating plate 1412 to rotate relative to the mounting component 142. Driving the first rotating plate 1411 or the second rotating plate 1412 to rotate relative to the mounting component 142 via the output shaft of the motor provides a simple connection method and low cost.
[0055] Optionally, the driving component 150 may include a first coil, a second coil, and a magnet. The first coil may be connected to a first rotating plate 1411, the second coil may be connected to a second rotating plate 1412, and the magnet may be connected to a mounting component 142. Thus, when the first coil is energized, a magnetic field is generated around it. This magnetic field couples with the magnetic field generated by the magnet, allowing the first rotating plate 1411 to attract the mounting component 142, placing the adjusting component 141 in a first state. When the second coil is energized, a magnetic field is generated around it. This magnetic field couples with the magnetic field generated by the magnet, allowing the second rotating plate 1412 to attract the mounting component 142, placing the adjusting component 141 in a third state. When both the first and second coils are energized, magnetic fields are generated around them. These magnetic fields, in conjunction with the magnetic field generated by the magnet, allow both the first and second rotating plates 1411 and 1412 to open their through holes 1421, placing the adjusting component 141 in a second state.
[0056] It should be noted that the magnet can be a separate device and can be mounted on the mounting part 142 by means of bonding, snap-fitting, or other methods. The magnet can also be integrated with the mounting part 142; for example, at least a portion of the mounting part 142 can be made of magnetic material to form a magnet.
[0057] Optionally, the driving component 150 may include a first electromagnet, a second electromagnet, and a magnet. The first electromagnet may be connected to a first rotating plate 1411, the second electromagnet may be connected to a second rotating plate 1412, and the magnet may be connected to a mounting component 142. Thus, when the first electromagnet is energized, it generates magnetism and attracts the magnet, placing the adjusting component 141 in a first state. When the second electromagnet is energized, it generates magnetism and attracts the magnet, placing the adjusting component 141 in a third state. When both the first and second electromagnets are energized, the cooperation of the first electromagnet, the second electromagnet, and the magnet allows both the first rotating plate 1411 and the second rotating plate 1412 to open the through holes 1421, i.e., placing the adjusting component 141 in a second state.
[0058] It should be noted that the magnet can be a separate device and can be mounted on the mounting part 142 by means of bonding, snap-fitting, or other methods. The magnet can also be integrated with the mounting part 142; for example, at least a portion of the mounting part 142 can be made of magnetic material to form a magnet.
[0059] In one exemplary embodiment, when the regulating component 140 has a first state and a second state, optionally, when the electronic device is not in use, the regulating component 140 can be in the second state, so that the moisture-absorbing component 130 can absorb water molecules inside the electronic device, and the communication between the first port 1111 and the second port 1112 can maintain the internal and external air pressure balance of the waterproof and breathable valve 100, as can be seen in [reference]. Figure 2 and Figure 4 When the electronic device is running, the adjustment component 140 can switch to the first state, as detailed in [reference needed]. Figure 1 , Figure 3 and Figure 5 After the adjustment component 140 is switched to the first state, the water molecules on the moisture absorption component 130 can be evaporated by heating and released through the waterproof and breathable membrane 120.
[0060] In another exemplary embodiment, when the regulating component 140 has a first state, a second state, and a third state, optionally, when the electronic device is not in use, the regulating component 140 can be in the third state, so that the moisture-absorbing component 130 can continuously absorb water molecules inside the electronic device. (See also...) Figure 8 During operation of the electronic device, the regulating component 140 can quickly switch from the third state through the second state to the first state. When the regulating component 140 passes through the second state, the internal and external air pressures of the electronic device can be balanced via the waterproof and breathable membrane 120. (See reference...) Figure 6 After the adjustment component 140 is switched to the first state, the water molecules on the moisture-absorbing component 130 can be evaporated by heating or other means and released through the waterproof and breathable membrane 120. (See reference...) Figure 7 .
[0061] One possible heating method is the heat generated by certain components within the electronic device during operation. Another possible heating method is: [Please refer to...] Figure 12 The waterproof and breathable valve 100 also includes a heating component 160, which generates heat by controlling its operation. When the heat generated during the operation of the electronic device causes the moisture-absorbing component 130 to expel moisture, no additional components are needed, reducing production costs and facilitating rapid heat dissipation, thus ensuring the normal operation of the electronic device. When the heat generated by the heating component 160 causes the moisture-absorbing component 130 to expel moisture, the heating component 160 can be connected to the adjusting component 140 and / or the first housing 110 to bring the heating component 160 closer to the moisture-absorbing component 130, making it easier for heat to be transferred to the moisture-absorbing component 130 and improving the moisture expulsion speed of the moisture-absorbing component 130.
[0062] Optionally, the heating assembly 160 can be disposed on the first rotating plate 1411 and / or the second rotating plate 1412. When the heating assembly 160 is disposed on one of the first rotating plate 1411 and the second rotating plate 1412, in order to facilitate the dehumidifying portion on the other of the first rotating plate 1411 and the second rotating plate 1412 to also dehumidify by heating, the first rotating plate 1411, the second rotating plate 1412, and the connecting structure 146 connecting the first rotating plate 1411 and the second rotating plate 1412 can be made of a material with high thermal conductivity. For example, the first rotating plate 1411, the second rotating plate 1412, and the connecting structure 146 can all be made of materials such as metal.
[0063] Optionally, when the first rotating plate 1411 is provided with a first rotating shaft 1451 and a first mounting portion 1454, the heating component 160 can be disposed on the first rotating shaft 1451 and / or the first mounting portion 1454. This avoids the wiring entanglement of the heating component 160 when the first rotating plate 1411 rotates, compared to directly disposing of the heating component 160 on the first rotating plate 1411. Further optionally, the heating component 160 can include a positive electrode and a negative electrode. When the first rotating plate 1411 is provided with two first mounting portions 1454, the positive and negative electrodes can be respectively mounted on the two first mounting portions 1454. In this case, the first rotating plate 1411 can be made of metal, so that the first rotating plate 1411 can generate heat after the heating component 160 is powered on, thereby causing the moisture-absorbing component 130 on the first rotating plate 1411 to expel moisture.
[0064] The waterproof and breathable valve 100 may include a controller 170, which is electrically connected to the drive component 150 and the heating component 160, and is used to control the opening and closing of the drive component 150 and the heating component 160. For example, when the regulating component 140 is in a first state, the controller 170 can control the heating component 160 to turn on so that the moisture-absorbing component 130 can dehumidify. The controller 170 can control the drive component 150 to drive it to the first state when the electronic device is turned on, and can control the drive component 150 to drive it to the second or third state when the electronic device is turned off.
[0065] Optionally, the waterproof and breathable valve 100 may further include a pressure detector 180, which may be electrically connected to the controller 170. Thus, when the pressure value detected by the pressure detector 180 exceeds a first preset range, the controller 170 may control the actuator 150 to activate, causing the regulating component 140 to be in a second state, thereby connecting the first port 1111 and the second port 1112, allowing the pressure in the gas channel 111 to be balanced with the external pressure via the waterproof and breathable membrane 120. Conversely, when the pressure value detected by the pressure detector 180 is within the first preset range, the controller 170 may control the actuator 150 to activate, causing the regulating component 140 to be in either a first or third state. Optionally, the pressure detector 180 may be located within the second sub-channel 1114.
[0066] Optionally, the waterproof and breathable valve 100 may further include a first humidity detector 191, which may be electrically connected to the controller 170. The first humidity detector 191 may be located within the second sub-channel 1114. Thus, when the humidity value detected by the first humidity detector 191 exceeds a second preset range, the controller 170 may control the drive unit 150 to activate, causing the adjustment component 140 to be in a second or third state, to absorb water molecules within the electronic device. Conversely, when the humidity value detected by the humidity detector is within the second preset range, the controller 170 may control the drive unit 150 to activate, causing the adjustment component 140 to be in a first state.
[0067] Optionally, the waterproof and breathable valve 100 may further include a second humidity detector 192, which may be electrically connected to the controller 170. The second humidity detector 192 may be located near the moisture-absorbing component 130. Thus, the controller 170 may control the drive unit 150 to open when the humidity value detected by the second humidity detector 192 exceeds a third preset range, thereby placing the regulating component 140 in a first state; and when the humidity value detected by the second humidity detector 192 is within the third preset range, the controller 170 may control the drive unit 150 to activate, thereby placing the regulating component 140 in a second or third state.
[0068] The waterproof and breathable membrane 120 can be made of expanded polytetrafluoroethylene (E-PTFE). E-PTFE has good weather resistance, chemical resistance, structural stability, and oleophobicity. In addition, the E-PTFE membrane material has a very low surface energy, and the surface tension will cause water droplets attached to it to transform into larger water droplets, making it difficult for them to enter the gas channel 111 of the first shell 110, thereby improving the performance of the waterproof and breathable valve 100 in blocking pollutants such as oil and dust.
[0069] The waterproof and breathable membrane 120 and the first shell 110 can be bonded together using processes such as injection molding, welding, bonding, and hot melting. To improve the reliability of the connection between the waterproof and breathable membrane 120 and the first shell 110, please refer to [the relevant documentation]. Figure 11 The first housing 110 may be provided with a receiving groove 112, and the waterproof and breathable membrane 120 may be partially located in the receiving groove 112 and connected to the first housing 110. For example, the receiving groove 112 may be provided on the inner wall surface of the first housing 110.
[0070] Optionally, a raised edge 113 may be provided on the outer surface of the first housing 110. The waterproof and breathable valve 100 can be connected to external components through the raised edge 113. The raised edge 113 may be provided in the middle of the first housing 110 or in the part of the first housing 110 near the second port 1112. The specific location of the raised edge 113 on the first housing 110 is not limited in this embodiment.
[0071] Alternatively, a sealing groove 1131 may be provided on the flange 113, and the waterproof and breathable valve 100 may also include a sealing ring provided in the sealing groove 1131 to improve the sealing performance when the waterproof and breathable valve 100 is connected to external components.
[0072] It should be noted that the first housing 110 can also be connected to the external components by means of bonding, ultrasonic welding, or metal welding, and this application embodiment does not limit this. Preferably, when both the first housing 110 and the external components are made of metal materials, the first housing 110 and the external components can be connected by metal welding to improve the sealing between them.
[0073] Please see Figure 13 The first housing 110 can be generally cylindrical to facilitate assembly with external components. It should be noted that the first housing 110 can also be generally prismatic or similar, and this embodiment does not limit it in this respect.
[0074] Secondly, embodiments of this application provide an electronic device. The electronic device may include a second housing and a waterproof and breathable valve 100. The second housing may have a receiving cavity and an opening communicating with the receiving cavity. The waterproof and breathable valve 100 may be disposed at the opening of the second housing, and its second port 1112 communicates with the receiving cavity. The electronic device may be any device that requires maintaining internal and external air pressure balance, such as a sensor device or a lidar device; embodiments of this application do not limit this.
[0075] Optionally, the electronic device can be an optical sensor. By setting a waterproof and breathable valve 100 on the optical sensor, fogging of the optical cover can be avoided, which would affect the light detection results.
[0076] Optionally, an opening can be provided at any position on the second housing to install the waterproof and breathable valve 100. Preferably, an opening can be provided on the part of the second housing corresponding to the highly absorbent device, so that the waterproof and breathable valve 100 can fully exert its moisture absorption and venting performance when installed at this opening.
[0077] The above disclosure is only a preferred embodiment of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
