Referring to fig. 1 to 3, an embodiment of the present invention discloses a waterproof vent valve, in which the waterproof vent valve 100 can be installed in an electronic device to balance the internal and external air pressures of the electronic device, so as to prevent the failure of pressure-sensitive devices in the electronic device, thereby ensuring the continued use. Specifically, the waterproof and breathable valve 100 may include a valve body 1, a movable member 2 and an electro-deformable member 3, the valve body 1 having a through passage 11, the passage 11 having a first opening 111 and a second opening 112, the first opening 111 being for communicating with the inside of the electronic device, the movable member 2 being capable of sealing the second opening 112 of the passage 11 to form a sealed state, wherein the sealed state is a state of preventing the communication between the air inside the electronic device and the air outside the electronic device. Alternatively, the movable member 2 may form an open state with the second opening 112, wherein the open state is a state that allows communication between air inside the electronic apparatus and air outside the electronic apparatus to balance air pressures inside and outside the electronic apparatus. The electro-deformation component 3 is arranged on the valve body 1, the electro-deformation component 3 can deform when being electrified, the electro-deformation component 3 is connected to the movable component 2, and the electro-deformation component 3 is used for enabling the movable component 2 to move relative to the second opening 112 of the channel 11 so as to switch between a sealing state and an opening state.

The waterproof and air-permeable valve 100 provided by this embodiment includes the electrical deformation component 3 capable of deforming when being energized, and the movable component 2 connected to the electrical deformation component 3, so that it is possible to control the movable component 2 to move between the sealed state and the opened state relative to the second opening 112 of the valve body 1 by controlling whether the electrical deformation component 3 is energized, that is, the waterproof and air-permeable valve 100 provided by this embodiment may be controlled to switch between the sealed state and the opened state, so as to prevent the circulation between the air inside the electronic device and the air outside the electronic device, or allow the circulation between the air inside the electronic device and the air outside the electronic device. Compared with a conventional passive waterproof breathable film, the waterproof breathable valve 100 in the embodiment can be actively opened to exhaust air so as to actively achieve air pressure balance between the inside and the outside of the electronic device, and particularly can be configured to perform air pressure balance between the inside and the outside of the electronic device in a specific scene, for example, the waterproof breathable valve 100 is switched from a sealed state to an open state in the specific scene, so as to allow air inside and outside the electronic device to circulate; and is not easily blocked to ensure the waterproof and breathable functions of the waterproof and breathable valve 100.

The electronic device to which the waterproof and breathable valve 100 is applied in the present application may be, but is not limited to, a mobile phone, a wearable device (e.g., a smart watch, a smart bracelet), and the like. The waterproof breather valve 100 disclosed in the present application is particularly effective for electronic devices with a compact interior space (e.g., smart watches), because the electronic components included in the electronic devices with a compact interior space are intensively arranged in the compact interior space, which is disadvantageous for heat dissipation, and particularly in some situations, the electronic components with high load may generate a large amount of heat in a short time. The heat accumulation in the compact space causes a rapid temperature rise, and thus a rapid air pressure rise inside the electronic device, which may cause some electronic components inside the electronic device to be in an unfavorable working environment, for example, the internal air pressure rise may cause the air pressure sensor to not accurately detect the air pressure outside the electronic device, and for example, the internal air pressure rise may cause the speaker to not output an optimal sound effect or even to not work normally, and so on. Therefore, the waterproof vent valve 100 disclosed by the application has a compact structure and small occupied space, and can effectively balance the internal air pressure and the external air pressure of the electronic equipment.

The overall shape of the waterproof breather valve 100 in the present application may be, but is not limited to, a columnar structure (e.g., a cylindrical structure, a square columnar structure), a block-like structure, and the like. For example, the overall shape of the waterproof breather valve 100 may be a cylindrical structure, and in particular, the valve body 1 may be a cylindrical structure, the movable member 2 may be a circular plate-shaped structure, and the electro-deformable member 3 may be a cylindrical structure, for example, the electro-deformable member 3 may be a spring structure.

In some embodiments, the material of the electrical deformation component 3 may be a memory metal or a piezoelectric material, so that when the interior of the electronic device needs to be communicated with the outside, the electrical deformation component 3 is connected with an electric current, and after the electrical deformation component 3 is connected with the electric current, the electrical deformation component 3 can be deformed to drive the movable component 2 to move in a direction away from the second opening 112 (e.g., in an x direction in fig. 2 and 3) to form an open state with the second opening 112, so that the interior of the electronic device can be communicated with the exterior of the electronic device through the channel 11 of the valve body 1 to keep air circulation, thereby balancing the air pressure inside the electronic device and the air pressure outside the electronic device; when the inside of the electronic device needs to be isolated from the outside, the current of the electro-deformation component 3 is cut off, and after the power of the electro-deformation component 3 is cut off, the electro-deformation component 3 recovers to deform to drive the movable component 2 to move along the direction (y direction in fig. 2 and 3) facing the second opening 112, so as to form a sealing state with the second opening 112, so as to seal the inside of the electronic device, and prevent external liquid from entering the inside of the electronic device. It can be seen that the waterproof breather valve 100 that this application provided can initiatively open and exhaust to make inside and outside keeping the circulation of air of electronic equipment, thereby realize the atmospheric pressure balance between inside and the outside of electronic equipment, in order to maintain the inside and outside atmospheric pressure balance of electronic equipment, avoid losing efficacy to the sensitive device of pressure.

Preferably, the material of the electro-deformable component 3 may be a memory metal, which stretches when heated and contracts when heat is dissipated, so as to drive the movable component 2 to move in a direction away from the second opening 112 (x direction in fig. 2 and 3) or in a direction close to the second opening 112 (y direction in fig. 2 and 3) by utilizing the stretching and contraction of the memory metal, so as to switch the movable component 2 between the sealed state and the opened state. That is, after the current is introduced to the electro-deformation component 3, the electro-deformation component 3 can be rapidly heated, so that the electro-deformation component 3 extends to push the movable component 2 open to form an open state, and thus the inside of the electronic device and the outside of the electronic device can be communicated through the channel 11 of the valve body 1, so that the communication of the air inside and outside the electronic device is realized, and the balance of the pressure inside and outside the electronic device is maintained; after the current of the electro-deformation component 3 is cut off, the electro-deformation component 3 can recover the original length to drive the movable component 2 to close the second opening 112 of the channel 11, so as to form a sealed state, and perform a closing function, so that the inside of the electronic device and the outside of the electronic device are in a closed non-conducting state, and external liquid is prevented from entering the inside of the electronic device through the channel 11 of the valve body 1.

When liquid enters from the outside, the movable part 2 can be firmly pressed against the valve body 1 by the pressure of the liquid, and the second opening 112 of the channel 11 is sealed to play a role of closing.

Further, this movable part 2's material can include elastic material and/or flexible material, and promptly, movable part 2 can take place deformation when the atress to when encapsulated situation, movable part 2 can suitably deform the interference and compress tightly valve body 1, makes the theoretical zero clearance of clearance accomplish between movable part 2 and the valve body 1, seals up the second opening 112 of passageway 11 well, improves the sealing performance of waterproof ventilation valve 100 when encapsulated situation.

That is, when the movable member 2 is in the sealed state, the first through hole 21 of the movable member 2 is shielded and sealed by the valve body 1, so that the first through hole 21 is isolated from the second opening 112 of the channel 11, and thus the interior of the electronic device is not communicated with the exterior of the electronic device through the first channel 11, the channel 11, and the exterior of the electronic device is prevented from entering the interior of the electronic device through the channel 11 of the valve body 1. And when the movable part 2 was located the open mode, there was the gap between the first through-hole 21 of movable part 2 and the valve body 1, and the first through-hole 21 of movable part 2 no longer was sheltered from by valve body 1 sealedly promptly for first through-hole 21 can communicate with the second opening 112 of passageway 11, thereby makes inside this first passageway 11, passageway 11 and the electronic equipment outside of passing through of electronic equipment intercommunication, in order to realize that the inside and outside air of electronic equipment switches on, and then keeps the internal and external pressure balance of electronic equipment.

Further, the number of the first through holes 21 may be plural, for example, in the embodiment shown in fig. 4, the number of the first through holes 21 may be four, the plural first through holes 21 are arranged at intervals along the circumferential direction of the movable member 2, and each first through hole 21 is arranged to be staggered with respect to the second opening 112 of the passage 11, so that when the movable member 2 is in the sealed state, each first through hole 21 is sealed by the valve body 1 and isolated from the second opening 112 to form the sealed state, and when the movable member 2 is in the opened state, each first through hole 21 may be communicated with the second opening 112 to form the opened state.

In some embodiments, as shown in fig. 2 to 4, the waterproof breather valve 100 may further include a valve cover 4, the valve cover 4 covers the outer periphery of the valve body 1, the movable member 2 is located between the valve cover 4 and the valve body 1, and the valve cover 4 is provided with a through second through hole 41, that is, the second through hole 41 is always in communication with the outside of the electronic device, and the second through hole 41 is in communication with the first through hole 21, so that in an open state, the inside of the electronic device can be in communication with the outside of the electronic device through the second through hole 41, the first through hole 21, the second opening 112 of the passage 11, and the first opening 111.

Illustratively, the bonnet 4 may include a base 42 and a wall 43 surrounding an edge of the base 42, the base 42 being provided with the aforementioned second through hole 41, and the one end of the valve body 1 and the movable member 2 being accommodated in a space defined by the wall 43. The valve cover 4 is provided to protect the valve body 1 and the movable member 2 by the valve cover 4.

Further, the second through hole 41 may be disposed corresponding to the first through hole 21, that is, the second through hole 41 may be disposed opposite to the first through hole 21. In this way, it can be ensured that the second through hole 41 and the first through hole 21 are always kept communicated, so as to ensure that the electronic device can be communicated with the outside of the electronic device through the second through hole 41, the first through hole 21, the second opening 112 of the channel 11 and the first opening 111 when in the open state, so that the air inside the electronic device can flow to the outside of the electronic device after sequentially passing through the first opening 111 and the second opening 112 of the channel 11, the first through hole 21 and the second through hole 41.

Further, the number of the second through holes 41 may be plural, for example, in the embodiment shown in fig. 4, the number of the first through holes 21 may be four, and the number of the second through holes 41 may be four, the plurality of second through holes 41 may be arranged at intervals along the circumferential direction of the base portion 42, and each of the second through holes 41 may be arranged opposite to the corresponding first through hole 21, so that each of the second through holes 41 may communicate with the corresponding first through hole 21 when the movable member 2 is in the open state.

In some embodiments, as shown in fig. 2 to 4, the valve body 1 may be provided with a receiving groove 12 surrounding the outer periphery of the channel 11, the receiving groove 12 has a third opening 121 facing the second opening 112, and the electro-deformable member 3 is disposed in the receiving groove 12 and surrounds the outer periphery of the channel 11. Through hiding the electric deformation part 3 and establishing in the holding tank 12 of valve body 1, not only can protect electric deformation part 3, can also make waterproof ventilation valve 100's overall structure compacter simultaneously, be favorable to waterproof ventilation valve 100's miniaturized design. In addition, the electro-deformation component 3 also surrounds the periphery of the channel 11, so that the side wall of the channel 11 can be used to guide the deformation of the electro-deformation component 3, so that the electro-deformation component 3 can deform according to a preset path, and thus it is ensured that the movable component 2 can move to form an open state with the second opening 112 along a direction away from the second opening 112 under the action of the electro-deformation component 3, or it is ensured that the movable component 2 can move to seal the second opening 112 to form a sealed state along a direction close to the second opening 112 under the action of the electro-deformation component 3.

It can be understood that since the second opening 112 is located in the accommodating groove 12 and is communicated with the third opening 121, when the movable member 2 seals the third opening 121 of the accommodating groove 12, the communication between the accommodating groove 12 and the outside of the electronic device is isolated, and the second opening 112 of the channel 11 can be sealed to isolate the communication between the inside of the electronic device and the outside of the electronic device. Similarly, when a gap is formed between the movable member 2 and the third opening 121, the third opening 121 communicates with the second opening 112 through the gap, so that the inside of the electronic device can communicate with the outside of the electronic device through the second through hole 41, the first through hole 21, the third opening 121, the gap, the second opening 112 of the passage 11, and the first opening 111.

In some embodiments, a surface of the movable member 2 facing the third opening 121 is provided with a guide portion 22, the guide portion 22 is movably connected to the receiving groove 12 to switch between a state of moving to be located outside the third opening 121 and a state of moving to be located inside the third opening 121 relative to the receiving groove 12, that is, when the sealed state is switched to the open state, the guide portion 22 moves to be located outside the third opening 121 relative to the receiving groove 12, and when the open state is switched to the sealed state, the guide portion 22 moves to be located inside the third opening 121 relative to the receiving groove 12, so that the cooperation between the guide portion 22 and the receiving groove 12 can be used to guide the movement of the movable member 2.

In some embodiments, the waterproof and air-permeable valve 100 further comprises a liquid detection assembly (not shown) disposed on the valve body 1, and the liquid detection assembly is mainly used for detecting whether liquid enters the channel 11. Therefore, when liquid is detected to flow into the channel 11, the electric deformation component 3 is favorable for being connected with current in time, and the movable component 2 can be moved along the direction close to the second opening 112 relative to the second opening 112 of the channel 11 in time to be switched from the open state to the sealed state, so that the liquid is prevented from flowing into the electronic equipment through the channel 11 of the waterproof ventilation valve 100, and the electronic elements in the electronic equipment are favorable for being protected.

As an alternative embodiment, the sensor 203 may be a pressure sensor, and when the sensor 203 detects that the air pressure inside the casing 201 is greater than the air pressure outside the casing 201, the sensor 203 sends a command signal to the main board 202, so that the main board 202 controls the electrical deformation component to switch on the current, so that the movable component moves relative to the second opening of the channel in a direction away from the second opening, and is switched from the sealed state to the open state, so as to allow air inside and outside the casing 201 to circulate, and balance the air pressure inside and outside the casing 201. Of course, in other embodiments, when the electronic device 200 is in water, in other embodiments, when the sensor 203 detects that the air pressure inside the housing 201 is smaller than the air pressure outside the housing 201, the sensor 203 also sends a command signal to the main board 202, so that the main board 202 controls the current for cutting off the electrostrictive component, so that the movable component moves in the direction close to the second opening relative to the second opening of the channel, and is switched from the open state to the sealed state, so as to isolate the air circulation inside and outside the housing 201, prevent the external liquid from entering the inside of the housing 201 through the waterproof breather valve 100, and enhance the use effect of the electronic device 200 in a severe environment.

As another alternative, the sensor 203 may be a temperature sensor, for example, when the temperature inside the casing 201 is increased during a video call, the sensor 203 may send a command signal to the main board 202 when the sensor 203 detects that the temperature inside the casing 201 is higher than the temperature outside the casing 201, so that the main board 202 controls the electrical deformation component to switch on the current, so that the movable component moves relative to the second opening of the channel in a direction away from the second opening, and is switched from the sealed state to the open state, so as to allow air circulation inside and outside the casing 201, balance the air pressure inside and outside the casing 201, release the internal heat, dissipate the heat, and enhance the use effect of the electronic device 200 in a harsh environment.
