Background

Some portable electronic devices (e.g., smartwatches, cell phones) have waterproof capabilities that achieve waterproof functions through a sealed structure. The sealing structure also isolates the ventilation of the inside and outside of the portable electronic device.

The embodiment of the invention discloses a portable electronic device, which is provided with a ventilation valve, wherein the ventilation valve can be controlled to be switched between a normally closed state and an open state, the normally closed state of the ventilation valve prevents ventilation between air inside a shell and air outside the shell, and the open state of the ventilation valve allows ventilation between the air inside the shell and the air outside the shell. As such, the portable electronic device may be configured to perform air pressure balancing between the inside and the outside in a particular scenario. Compared with the conventional passive waterproof breathable film, the breathable valve disclosed by the embodiment of the invention can realize the air pressure balance between the inside and the outside of the portable electronic device and is not easy to block. The technical scheme of the invention will be further described with reference to the examples and the accompanying drawings.

Referring to fig. 1-4, in one embodiment, a portable electronic device 100 includes a housing 10, a vent valve 20, and a controller 30. A ventilation valve 20 is connected to the housing 10, the ventilation valve 20 being in a normally closed state, wherein the normally closed state prevents communication between air inside the housing and air outside the housing. The controller 30 is electrically connected to the breather valve 20 for controlling the breather valve 20 to be switched from the normally closed state to the open state, so that communication between the air inside the housing 10 and the air outside the housing 10 is allowed to balance the air pressure inside and outside the housing 10.

The portable electronic device 100 may be a cell phone, a wearable device (e.g., a smart watch), etc., but is not limited thereto. The technical solutions disclosed in the above embodiments may be used to actively balance the air pressure inside and outside the portable electronic device, for example, to switch the ventilation valve 20 from a normally closed state to an open state in a specific scenario, so as to allow air inside and outside the electronic device to circulate.

The technical solution disclosed in the above embodiments of the present invention has a more obvious effect on portable electronic devices (such as smartwatches) with compact internal space, because the electronic components contained in the portable electronic devices are intensively arranged in the compact space, which is not beneficial to heat dissipation, and particularly, in some situations, high-load electronic components can generate a large amount of heat in a short time. Heat is concentrated in a compact space causing a rapid rise in temperature and thus in the air pressure inside the portable electronic device. This may cause some electronic components in the portable electronic device to be in a disadvantageous working environment, for example, the air pressure sensor cannot accurately detect the air pressure outside the portable electronic device due to the rise of the internal air pressure, and the speaker may not output the optimal sound effect due to the rise of the internal air pressure, or even not work normally. In addition, higher internal air pressures relative to external air pressures can also stress the seal and even cause seal failure or shell rupture. The ventilation valve can provide a much larger and less prone to blockage passage than the micro-holes of the passive waterproof and breathable membrane in the open state, thereby more efficiently achieving air pressure balance between the inside and the outside of the portable electronic device.

In one embodiment, the breather valve 20 includes a valve body 21, a moving member 22 connected to the valve body 21, and a driving member 23. One of the valve body 21 and the moving member 22 is connected to the housing 10, when the breather valve 20 is in a normally closed state, the valve body 21 and the moving member 22 cooperate with each other to form a sealed state, preventing the circulation between the air inside the housing 10 and the air outside the housing 10, and the driving member 23 is electrically connected to the controller 30, and the driving member 23 is configured to drive the moving member 22 such that at least a portion of the moving member 22 moves relative to the valve body 21, thereby forming a gap 24 between the valve body 21 and the moving member 22, and allowing the air inside the housing 10 and the air outside the housing 10 to circulate through the gap 24. The ventilation valve 20 may be implemented in a number of different embodiments, each of which will be described in detail below.

Example 1

In the present embodiment, the breather valve 20 is disposed inside the housing 10, for example, the inner surface of the housing 10 is provided with a housing chamber 11, the housing chamber 11 communicates with the inner space of the housing 10, and includes an opening facing the inner space of the housing 10, and the breather valve 20 is housed in the housing chamber 11. The housing 10 is further provided with a first through hole 12 communicating with the outside thereof, the first through hole 12 extending inwardly from the outer surface of the housing 10 until communicating with the receiving cavity 11. When the ventilation valve 20 is in a normally closed state, air inside the casing 10 cannot flow outward. When the ventilation valve 20 is in the open state, air inside the casing 10 can flow out of the casing 10 through the gap 24 and the first through hole 12.

With the above arrangement, the ventilation valve 20 is disposed near the first through hole 12, so that air inside the housing 10 passes through the ventilation valve 20 and then rapidly flows to the outside of the housing 10, which is beneficial to rapidly realizing air pressure balance inside and outside the housing 10.

Those having ordinary skill in the art will appreciate that the arrangement of the breather valve 20 relative to the housing 10 is necessary to ensure that air within the housing 10 flows out of the housing 10 after passing through the gap 24. The arrangement of the ventilation valve 20 with respect to the housing 10 is not limited to the above-described manner, and may be changed according to actual needs. For example, the receiving cavity 11 may extend directly from the inner surface of the housing 10 to the outer surface of the housing 10, with one end of the breather valve 20 being substantially flush with the outer surface of the housing 10. At this time, the end of the air-permeable valve 20 is directly exposed, and the housing 10 no longer needs to be provided with the first through hole 12. Other arrangements of the ventilation valve 20 are not described in detail herein.

In this embodiment, the portable electronic device 100 includes a dust-proof net 40, where the dust-proof net 40 is connected to the housing 10 and covers the first through hole 12, so as to prevent particles such as dust from entering the first through hole 12, and thus has an opportunity to enter the housing 10. Specifically, the first through hole 12 may be a stepped hole, that is, two holes having different diameters and communicating with each other, and the dust-proof net 40 is accommodated in the hole having the larger diameter and covers the hole having the smaller diameter.

In this embodiment, the moving member 22 is connected to the housing 10, the moving member 22 is located between the housing 10 and the valve body 21, the moving member 22 and the valve body 21 are respectively provided with a second through hole 221 and a third through hole 211, the second through hole 221 communicates with the first through hole 12, and the third through hole 211 communicates with the interior of the housing 10. In the normally closed state of the breather valve 20, the valve body 21 and the moving member 22 cooperate with each other to isolate the third through hole 211 from the second through hole 221. In the open state of the breather valve 20, the third through hole 211 communicates with the second through hole 221 through the gap 24, thereby allowing the air inside the housing 10 to flow outside the housing 10 after passing through the third through hole 211, the gap 24, the second through hole 221, and the first through hole 12 in order.

In this embodiment, the breather valve 20 further includes a valve cover 25, and the moving member 22 is fixed to the housing 10 through the valve cover 25. Specifically, the moving member 22 is fixed to the valve cover 25, and the valve cover 25 is fixed to the bottom surface of the housing chamber 11 of the housing 10. In the present embodiment, the valve cover 25 includes a base 251 and a wall portion 252 surrounding an edge of the base 251, and one end of the valve body 21 and the mover 22 are accommodated in a space defined by the wall portion 252. The outer end surface of the base 251 is fixed to the bottom surface of the housing chamber 11. The valve body 21 and the valve cover 25 may be connected to each other by conventional connection means, such as screws, glue, mechanical snap-fit, etc., as may the connection between the valve cover 25 and the housing 10.

In the present embodiment, the valve cover 25 is provided with the fourth through hole 253, and the fourth through hole 253 and the first through hole 12 communicate with each other through the gap 26 between the outer end surface of the base 251 and the inner surface of the housing 10. In other embodiments, the fourth through hole 253 may be disposed opposite to the first through hole 12, and in this case, the gap 26 may be omitted. In the opened state of the air-permeable valve 20, air inside the casing 10 flows to the outside of the casing 10 after passing through the third through hole 211, the gap 24, the second through hole 221, the fourth through hole 253, and the first through hole 12 in this order.

The valve cover 25 can protect the valve body 21 and the mover 22, and can serve as a reference for positioning the mover 22 by the base 251 and the wall 252 of the valve cover 25. It should be noted that in other embodiments, the valve cover 25 may be omitted, and the moving member 22 and/or the valve body 21 may be directly connected to the inner surface of the housing 10 by conventional connection methods, as desired.

In the present embodiment, the elastic sealing ring 50 is provided between the base 251 of the valve cover 25 and the inner surface of the housing chamber 11, and the elastic sealing ring 50 is elastically deformed by being pressed by the base 251 and the inner surface of the housing chamber 11, thereby forming a sealing structure to seal between the base 251 and the inner surface of the housing chamber 11, and preventing a gap from being present between the base 251 and the inner surface of the housing chamber 11 to allow liquid/air to pass therethrough. It will be appreciated that an elastomeric seal (not shown) may also be provided between the valve body 21 and the inner surface of the wall portion 252 of the valve cover 25 to prevent a gap from being present between the valve body 21 and the inner surface of the wall portion 252 of the valve cover 25 to allow liquid/air to pass therethrough.

In the present embodiment, the valve body 21 is entirely cylindrical, and the third through hole 211 extends from one end (top end in fig. 3) of the valve body 21 to the opposite end (bottom end in fig. 3). The moving member 22 is located at the top end of the valve body 21. The moving member 22 may be arranged in a number of different ways. For example, in the first arrangement, the edge of the moving member 22 is fixedly connected to the edge of the valve body 21, the remaining portions are not connected to each other except at the fixedly connected edges, and the end surfaces of the moving member 22 and the valve body 21 where the third through hole 211 is formed are kept in close contact to form a seal, thereby isolating the third through hole 211 from the second through hole 221 and preventing air from flowing from the third through hole 221 to the second through hole 221. The moving member 22 has an elastic deformation capability, and a part of the moving member 22 can move relative to the valve body 21. When driven by the driving member 23, the moving member 22 is elastically deformed so that a portion thereof in close contact with the end surface of the valve body 21 where the third through hole 211 is formed is separated from the end surface, thereby forming a gap 24. In this way, the moving member 22 can return to the sealing state with the valve body 21 by means of its own elastic deformation, without providing an additional elastic return member, which is advantageous in simplifying the structure. In the second arrangement, the moving member 22 is not connected to the valve body 21, and the whole thereof is movable relative to the valve body 21, thereby allowing a gap 24 to be formed between the moving member 22 and the valve body 21. With this arrangement, the movable member 22 does not need to be fixed, which is advantageous in simplifying the manufacturing process and saving costs. The function of the above-described construction of the valve body 21 and the moving member 22 will be more clear from the following detailed description of the driving member 23.

In this embodiment, the driving member 23 is an electromagnet, the moving member 22 includes a magnet 222, and after the current is applied, a repulsive force is generated between the driving member 22 and the magnet 222, and the repulsive force pushes the moving member 22 to generate the gap 24. Specifically, the mover 22 includes a base plate 223 having elastic deformability. The edge of the base plate 223 is fixedly connected to the edge of the valve body 21, the rest is not connected to each other except at the fixedly connected edge, and the end surfaces of the base plate 223 and the valve body 21 where the third through hole 211 is formed are kept in close contact to form a seal. The magnet 222 is fixed to the base plate 223, and the magnet 222 is located between the base plate 223 and the inner surface of the base 251 of the end cap 25. There is a gap between the magnet 222 and the inner surface of the base 251 that allows the magnet 222 to move toward the inner surface of the base 251 until it contacts the inner surface of the base 251. The repulsive force can push the magnet 222 to move away from the valve body 21, and drive the base plate 223 to elastically deform, so that the gap 24 is formed between the valve body 21 and the base plate 223 of the moving member 22. When the repulsive force generated by the electromagnet disappears, the base plate 223 returns to the original shape, and thus returns to close contact with the end surface of the valve body 21 where the third through hole 211 is formed, thereby forming a seal.

The moving member 22 may also be arranged in different ways. For example, as shown in fig. 5, the base plate 223 is not connected to the valve body 21, and the edge of the base plate 223 is tightly sandwiched between the valve body 21 and the valve cover 25 so as not to move, for example, by bringing the bottom surface of the base plate 223 into contact with the edge of the valve body 21 at the edge thereof, the top surface of the base plate 223 is further formed with a projection 224 at the edge thereof, and the projection 224 is brought into contact with the inner surface of the valve cover 25, so that the edge of the base plate 223 is tightly sandwiched between the valve body 21 and the valve cover 25. When the driving member 23 generates a repulsive force to the magnet 222, the magnet 222 moves away from the valve body 21, and drives the base plate 223 to elastically deform, so that the gap 24 is formed between the valve body 21 and the base plate 223 of the moving member 22. For another example, the base plate 223 is not connected to the valve body 21, and the entire base plate 223 is movable with respect to the valve body 21. When the driver 23 generates a repulsive force against the magnet 222, the base plate 223 moves away from the valve body 21 under the guide of the inner surface of the wall 252 of the valve cover 25 until the magnet 222 contacts the inner surface of the base 251 of the valve cover 25. In order that the base plate 223 can be restored to the original position and closely contacted with the end surface of the valve body 21 to form a seal after the repulsive force generated by the electromagnet is removed, one or more springs (not shown) may be provided between the base plate 223 and the base 251 of the end cap 25, both ends of which respectively collide with the base plate 223 and the base 251, the springs being in a compressed state, and the springs pushing the base plate 223 to be restored to the original position and closely contacted with the end surface of the valve body 21 to form a seal after the repulsive force generated by the electromagnet is removed. The base plate 223 is made of a material capable of being elastically deformed (e.g., silicone), and is elastically deformed by the urging force of the spring, so that a seal is formed between the base plate 223 and the end face of the valve body 21 in contact therewith.

As shown in fig. 3, in the present embodiment, the end surface of the valve body 21 where the third through hole 211 is formed is a plane, and the bottom surface of the moving member 22 that engages with the end surface is also a plane, and the bottom surface of the moving member 22 is closely adhered to the end surface of the valve body 21. It is to be understood that the construction of the valve body 21 and the moving member 22 is not limited thereto, as long as a seal can be formed between the moving member 22 and the valve body 21. For example, as shown in fig. 6 and 7, the valve body 21 is provided with a first positioning portion facing the moving member 22, and the moving member 22 is correspondingly provided with a second positioning portion, and the second positioning portion and the first positioning portion cooperate to form the sealed state. Specifically, the first positioning portion is a recess formed in the valve body 21 and communicating with the inside of the housing 10, and the second positioning portion is a projection 225 provided on a side of the moving member 22 facing the valve body 21. The protrusion 225 may be truncated cone (see fig. 6), and the third through hole 211 may be a recess, and the protrusion 225 may be elastically deformed by being pressed by the inner surface of the third through hole 211 after being received in the third through hole 211, thereby forming a seal preventing the ventilation of the inside and outside of the housing 10. The protrusion 225 may also have a hemispherical shape (see fig. 7), in which case the recess communicates with the third through hole 211 and has a spherical inner surface, and the protrusion 225 is elastically deformed by being pressed by the spherical inner surface after being received in the recess, thereby forming a seal preventing ventilation of the inside and outside of the housing 10.

In this embodiment, the driving member 23 is an electromagnet, which includes a coil 231 and an iron core surrounded by the coil 231. For simplicity of construction, the valve body 21 is made of magnetically conductive material, and the iron core is a part of the valve body 21. Specifically, the valve body 21 further includes an annular receiving space 212 surrounding the third through hole 211, so that a cylinder 213 separating the third through hole 211 from the receiving space 212 is formed, the cylinder 213 serves as an iron core, a coil 231 is received in the receiving space 212, and both ends of the coil 231 extend into the housing 10 respectively around the outer surface of the cylinder 213, and current can flow in from one end thereof and flow out from the other end thereof. It will be appreciated that the core may also be a separately manufactured element which may be connected to the valve body 21 by conventional connection means. When the coil 231 is energized under the control of the controller 30, the coil 231 cooperates with the iron core to generate a repulsive force to the magnet 222, which is vanished when the coil 231 is energized under the control of the controller 30. In the present embodiment, since the valve body 21 is made of a magnetically conductive material, the repulsive force is eliminated, and the attractive force between the magnet 222 and the valve body 21 also drives the moving member 22 to move toward the valve body 21 until both return to the original sealed state. The electromagnet-based driving piece 23 is simple and reliable in structure, and the driving piece 23 can be controlled to be switched between a normally closed state and an open state only through on-off of current. In addition, the ventilation valve 20 is normally closed based on the driving member 23, that is, the ventilation valve 20 is normally closed to isolate the inside and the outside of the casing 10, and the ventilation valve 20 is switched to the open state only by powering the driving member 23 in a specific scene, which is beneficial to reducing the power consumption of the portable electronic device.

Example two

Referring to fig. 8, compared with the ventilation valve shown in fig. 3, only the elastic member 27 is added to the ventilation valve in this embodiment, and the other elements are the same, and the same reference numerals are used for the same elements. The present embodiment will be described in detail below.

In the present embodiment, the magnet 222 may be replaced by a metal member that can be attracted by magnetic force, and for convenience of description, the magnet 222 and the metal member that can be attracted by magnetic force are collectively referred to as a mating portion. After the coil 231 is energized, a suction force is generated between the coil 231 and the engaging portion, the suction force causes the moving member 22 and the valve body 21 to be engaged with each other to form a sealed state, after the coil 231 of the driving member 23 is de-energized, the suction force disappears, and the elastic member 27 drives the moving member 22 to move in a direction away from the valve body 21, thereby generating the gap 24.

In a specific scenario, the controller 30 controls the coil 231 to be de-energized to switch the air-permeable valve 20 to an open state to allow communication between the air inside the housing 10 and the air outside the housing 10 to equalize the air pressure inside and outside the housing 10. When necessary, the controller 30 controls the coil 231 to be energized, and the suction force generated after the energization overcomes the acting force exerted by the elastic member 27 on the moving member 22 to drive the moving member 22 to move until the valve body 21 returns to the sealing state, so as to switch the ventilation valve 20 to the normally closed state.

In the present embodiment, the elastic member 27 is provided between the base plate 223 and the valve body 21. Specifically, the end surface of the valve body 21 provided with the third through hole 211 is provided with a receiving hole 214, one end of the elastic member 27 is received in the receiving hole 214, the other end thereof is in contact with the bottom surface of the substrate 223 facing the valve body 21, and the elastic member 27 is in a compressed state for applying a pushing force to the substrate 223.

It will be appreciated that the elastic member 27 is also disposed between the base plate 223 and the end cap 25, and both ends thereof are respectively fixed to the base plate 223 and the end cap 25, which serve to apply a tensile force to the base plate 223. When the coil 231 is powered off, the substrate 223 is pulled away from the valve body 21 by the pulling force of the elastic piece 27 to form a gap 24, and when the coil 231 is powered on, the attractive force generated by the cooperation of the coil 231 and the iron core overcomes the pulling force of the elastic piece 27 to drive the substrate 223 to move until the substrate 223 and the valve body 21 are mutually matched to form a sealing state.

Example III

Unlike the first and second embodiments, in which the switching of the state of the breather valve 20 involves the power-off of the coil 231, in this embodiment, the coil 231 is always kept in the energized state during the switching of the state of the breather valve 20.

The ventilation valve of this embodiment and the ventilation valve disclosed in example one have exactly the same construction, and like elements are denoted by like reference numerals. Referring to fig. 9, a current direction control circuit 31 is connected between the coil 231 and the controller 30, and the controller 30 can change the direction of the current flowing into the coil 231 through the current direction control circuit 31, so that the coil 231 and the iron core cooperate to generate repulsive force or attractive force to the magnet 222 according to the requirement. In a specific scenario, the controller 30 controls a current in a first direction to flow into the coil 231, and the cooperation of the coil 231 and the iron core generates a repulsive force to the magnet 222, pushing the substrate 223 to move away from the valve body 21, thereby forming the gap 24 between the substrate 223 and the valve body 21. When necessary, the controller 30 controls the current in the second direction to flow into the coil 231, and the coil 231 and the iron core cooperate to generate attraction force to the magnet 222, so that the substrate 223 is pulled to move toward the valve body 21 until the substrate 223 and the valve body 21 cooperate with each other to form a sealed state.

It will be appreciated that modifications to the coil 231 of the ventilation valve disclosed in example one may also be made to the ventilation valve of this embodiment. Specifically, in the embodiment one of the ventilation valve disclosed, two sets of coils 231 are disposed on the outer surface of the cylinder 213, and the winding directions of the two sets of coils 231 are opposite. In a specific scenario, the controller 30 controls the current to flow into the first set of coils 231 and de-energizes the second set of coils 231, and the cooperation of the first set of coils 231 and the iron core generates a repulsive force to the magnet 222, pushing the substrate 223 to move away from the valve body 21, thereby forming the gap 24 between the substrate 223 and the valve body 21. When necessary, the controller 30 controls the current to flow into the second set of coils 231 to cut off the power to the first set of coils 231, the second set of coils 231 and the iron core cooperate to generate the attraction force to the magnet 222, and the substrate 223 is pulled to move towards the direction approaching the valve body 21 until the substrate 223 and the valve body 21 cooperate to form a sealing state.

Example IV

In the ventilation valve of this embodiment, a linear actuator is used instead of the electromagnet type driving unit shown in fig. 3, and the remaining elements are the same, and the same reference numerals are used for the same elements. The present embodiment will be described in detail below.

Referring to fig. 10, the driving member 23 in the present embodiment is a linear actuator, and includes a body 232, a guide rod 233 extending from one end of the body, and a slider 234 capable of sliding along the guide rod 233. The driver 23 is fixed in the third through hole 211 of the valve body 21. The body 232 includes a motor for driving the guide rod 233 to rotate, and the slider 234 connected to the guide rod 233 can move linearly along the guide rod 233 under the driving of the guide rod 233.

The slider 234 is in contact with the moving member 22, and movement of the slider 234 drives at least a portion of the moving member 22 to move relative to the valve body 21, thereby forming a gap 24 between the valve body 21 and the moving member 22. In this embodiment, the slider 234 is fixed to the moving member 22, and the slider 234 can push at least a portion of the moving member 22 away from the valve body 21, and can also pull at least a portion of the moving member 22 to move toward the valve body 21 until the moving member 22 and the valve body 21 cooperate with each other to form a sealed state.

It will be appreciated that the slider 234 may not be fixed to the moving member 22, and that the slider 234 may only push at least a portion of the moving member 22 away from the valve body 21 to form the gap 24. At this time, the breather valve 20 further includes an elastic restoring member (not shown) for applying a pushing force or a pulling force to the moving member 22, which is used for driving the moving member 22 to return to cooperate with the valve body 21 to form a sealed state after the sliding block 234 is out of contact with the moving member 22.

Example five

Referring to fig. 11, compared with the ventilation valve shown in fig. 3, the ventilation valve in this embodiment adjusts the position of the moving member, and the other elements are the same, and the same reference numerals are used for the same elements. The present embodiment will be described in detail below.

In the present embodiment, the valve body 21 has one end (top end in fig. 11) near the housing 10 and one end (bottom end in fig. 11) near the inner space of the housing 10, and the moving member 22 is located at the bottom end of the valve body 21. The valve body 21 is connected to the housing 10, for example by a valve cover 25 to the housing 10. I.e. the valve body 21 is located between said housing 10 and said moving 22, the first through hole 12 communicates with both said housing exterior and said third through hole 211, and the second through hole 221 communicates with the housing 10 interior. In the normally closed state, the valve body 21 and the moving member 22 cooperate with each other to isolate the third through hole 211 from the inside of the housing 10, and in the open state, the third through hole 211 communicates with the second through hole 221 through the gap 24 and thus communicates with the inside of the housing 10.

The relationship of the moving member 22 and the valve body 21 can be referred to the relationship of the moving member 22 and the valve body 21 disclosed in the first embodiment. For example, the edge of the moving member 22 is fixedly connected to the edge of the valve body 21, the remaining portions are not connected to each other except at the fixedly connected edges, and the end surfaces of the moving member 22 and the valve body 21 where the third through hole 211 is formed are kept in close contact to form a seal, thereby isolating the third through hole 211 from the second through hole 221. The moving member 22 has an elastic deformation capability, and a part of the moving member 22 can move relative to the valve body 21. When driven by the driving member 23, the moving member 22 is elastically deformed so that a portion thereof in close contact with the end surface of the valve body 21 where the third through hole 211 is formed is separated from the end surface, thereby forming a gap 24. The relationship between the moving member 22 and the valve body 21 is not limited thereto, and the relationship between the moving member 22 and the valve body 21 has been described in detail in the foregoing embodiment, and will not be described here again.

It can be understood that the driving member 23 in this embodiment may be an electromagnet driving member disclosed in the second embodiment, the second embodiment or the third embodiment, or a linear driving member disclosed in the fourth embodiment, which is not described herein.

Example six

Referring to fig. 12, compared with the ventilation valve shown in fig. 3, the ventilation valve in this embodiment adjusts the position of the moving member, and the other elements are the same, and the same reference numerals are used for the same elements. The present embodiment will be described in detail below.

In the present embodiment, the valve body 21 is connected to the housing 10, and may be connected to the housing 10 through a valve cover 25, for example. The first through hole 12 communicates with the outside of the housing 10, and the third through hole 211 communicates with the inside of the housing. The moving member 22 is located in the third through hole 211, and in the normally closed state of the air vent valve 20, the moving member 22 prevents air from passing through the third through hole 211, and in the open state of the air vent valve 20, the first through hole 12 and the third through hole 211 communicate.

In this embodiment, the third through hole 211 is a stepped hole, that is, includes two holes having different diameters and communicating with each other, and the moving member 22 is located in the hole having the larger diameter and is located near one end (top end in fig. 12) of the first through hole 12, and the moving member 22 located in the third through hole 211 blocks the third through hole, so that air can be prevented from passing through the third through hole 211. There is a space that can accommodate the mover 22 between the end surface of the valve body 21 where the third through hole 211 is formed and the end cover 25, or between the case 10 when the end cover 25 is omitted. When driven by the driving member 23, the moving member 22 moves in a direction away from the third through hole 211 until contacting the valve cover 25 or the housing 10, at which time a gap 24 is formed between the edge of the moving member 22 and the edge of the third through hole 211. The first through hole 12 communicates with the third through hole 211 through a gap, thereby allowing air communication between the inside and the outside of the housing 10.

It will be appreciated that the movable member 22 may be located at other positions in the third through hole 211, for example, at one end (bottom end in fig. 12) near the inner space of the housing 10, and at this time, another end cap (not shown) may be provided, which may be connected to the valve body 21 or the housing 10, with a space for accommodating the movable member 22 being provided between the inner surface of the end cap and the end surface of the valve body 21 where the third through hole 211 is formed. When driven by the driving member 23, the moving member 22 moves away from the third through hole 211 until contacting the valve cover. It is understood that the skilled person in this embodiment may set the moving member 22 at other positions in the third through hole 211 according to actual needs, which will not be described herein.

In this embodiment, the breather valve 20 may further include an elastic restoring member (not shown), which may be a spring, one end of which is fixed to the valve body 21 and the other end of which is fixed to the moving member 22. The elastic restoring member is used to apply a pulling force to the moving member 22, and when the driving member 23 no longer applies a repulsive force to the moving member 22, the pulling force of the elastic restoring member pulls the moving member 22 back into the third through hole 211.

It can be understood that the driving member 23 in this embodiment may be an electromagnet driving member disclosed in the second embodiment, the second embodiment or the third embodiment, or a linear driving member disclosed in the fourth embodiment, which is not described herein.

Referring again to fig. 4, the controller 30 disclosed in this embodiment is capable of reading computer readable instructions stored in the memory of the portable electronic device 100, which can cause the controller 30 to perform control of the breather valve 20 and other elements. The controller 30 may be a Central Processing Unit (CPU) of the portable electronic device 100, an Application Specific Integrated Chip (ASIC), other microcontrollers, or the like.

In one embodiment, the controller 30 controls the ventilation valve 20 to switch from the normally closed state to the open state in response to an event meeting a preset condition. In this embodiment, the portable electronic device 100 further includes a speaker 90 electrically connected to the controller 30, and the speaker 90 needs to operate normally under a predetermined range of air pressure. When the internal space of the portable electronic device 100 is compact and electronic components are densely arranged in the internal space, in some scenarios, some electronic components (e.g., a central processing unit) may generate a large amount of heat under a high load, and the large amount of heat may increase the air pressure inside the portable electronic device 100 above the air pressure of the external environment, which may affect the normal operation of the speaker 90, so that the output of the speaker is distorted. To solve the above problem, the event meeting the preset condition may be the activation of the speaker 90, i.e., the controller 30 controls the speaker 90 to output sound. Thus, as long as the controller 30 detects a scene (e.g., voice call, video call) in which the speaker needs to be started, the controller 30 switches the ventilation valve 30 from the normally closed state to the open state, so that air inside and outside the housing 10 can circulate, and air pressure balance inside and outside the housing 10 is achieved. So that the speaker 90 can always operate within the normal air pressure range. It will be appreciated that the event meeting the preset condition is not limited to the foregoing situation, for example, it may be a situation where a voice call, a video call, etc. lasts for a preset time, so that it is beneficial to exclude a scenario where a voice call, a video call, etc. lasts for a short time, and the scenario generally does not generate a lot of heat. The event meeting the preset condition may be other situations that can cause the internal temperature of the portable electronic device 100 to rise rapidly, for example, the portable electronic device 100 plays the video for a preset time, the cpu runs the game for a preset time under a high load, etc.

In an embodiment, the portable electronic device 100 further includes an input device 70 electrically connected to the controller 30, wherein the input device 70 is configured to receive input from a user, and may be a touch display, a mechanical button, a touch response button, or the like. An event meeting the preset condition may also be the controller 30 receiving a specific command input by the user through the input device 70. This allows, when a user finds an abnormality, such as when the volume of sound output from the speaker 90 is significantly lower than the past normal volume, a command is sent through the input device 70 to switch the ventilation valve 30 from the normally closed state to the open state, so that air inside and outside the housing 10 can circulate, and air pressure balance inside and outside the housing 10 is achieved.

In one embodiment, the portable electronic device 100 further includes a sensor assembly 80 electrically connected to the controller 30, and the sensor assembly 80 may include various sensors, such as a temperature sensor, a barometric sensor, and the like. The temperature sensor is used for detecting the temperature inside the shell, and the air pressure sensor is used for detecting the air pressure inside the shell. The controller 30 may monitor the temperature and air pressure inside the case 10 according to the outputs of the temperature sensor and the air pressure sensor. The event meeting the preset condition may be a change of the temperature inside the housing 10 meeting a specific rule, or a change of the air pressure inside the housing 10 meeting a specific rule. Specifically, the change in the temperature inside the case 10 satisfying a specific rule may be: the temperature value exceeds the preset value, and the speed of temperature rise (temperature rise value per unit time) reaches the preset value. The change in the temperature inside the housing 10 satisfying a specific rule may be: the air pressure value exceeds the preset value, and the speed of air pressure rise (the temperature rise value per unit time) reaches the preset value. It will be appreciated that the variation of the temperature/air pressure inside the housing 10 that satisfies the specific law is not limited to the foregoing, and can be adjusted according to the actual needs. The above-mentioned technical solution may enable the portable electronic device 100 to perform internal and external air pressure balancing in response to a change of the external environment, for example, when the air pressure detected by the air pressure sensor continuously decreases, the controller 30 may evaluate that the user may travel to a high altitude location, and at this time, the controller 30 may switch the ventilation valve 20 to an open state, so that air inside and outside the housing 10 can circulate, so that the output of the air pressure sensor more accurately reflects the air pressure of the external environment.

Referring again to fig. 4, the controller 30 is further configured to control the vent valve 20 to switch from the open state to the normally closed state in response to a specific event, wherein the specific event includes detecting that liquid is entering between the housing 10 and the vent valve 20. Specifically, the breather valve 20 further includes a liquid detection component 60, where the liquid detection component 60 is disposed on the valve body 21 or the moving member 22, and the liquid detection component 60 is in communication with the outside of the housing 10, and is used for detecting whether a liquid enters between the housing 10 and the breather valve 20. Referring to fig. 13, in the present embodiment, the liquid detecting assembly 60 includes two electrodes 61 spaced apart from each other and a resistance detecting unit 62 electrically connected to air, the resistance detecting unit is used for detecting a resistance value between the two electrodes 61, and the controller 30 determines whether a liquid is introduced between the housing 10 and the air-permeable valve 20 according to the resistance value between the two electrodes 61.

The liquid detection assembly 60 operates on the following principle: normally, the resistance detection unit 61 detects that the resistance between the electrodes 61 is infinity; when liquid enters between the housing 10 and the breather valve 20, both electrodes 61 are in contact with the liquid, and the resistance between the electrodes 61 decreases. The controller 30 determines whether or not liquid has entered between the housing 10 and the air-permeable valve 20 based on the change in resistance between the electrodes 61. In the present embodiment, the electrode 61 is a wire provided in the housing space 212 (see fig. 3) of the valve body 21. The second through hole 221 and the fourth through hole 253 are located right above the accommodating space 212. The receiving space 212 communicates with the first through hole 12 through the second through hole 221 and the fourth through hole 253. After the night drip flows into the first through hole 12, it can flow into the receiving space 212 through the fourth through hole 253 and the second through hole 221. A part of the electrode 61 is located in the accommodating space 212, and the other part extends to the inside of the case 10 through the bottom of the accommodating space 212 and is connected to the resistance detecting unit 61. Thus, when the liquid flowing into the accommodating space 212 contacts both of the electrodes 61, the controller 30 can detect that the liquid flows between the housing 10 and the air-permeable valve 20 according to the change of the resistance between the electrodes 61. In the above-mentioned scheme, when the liquid flowing into the space between the housing 10 and the ventilation valve 20 is detected, the ventilation valve 20 is switched from the open state to the normally closed state, so that the liquid is prevented from flowing into the housing 10 through the ventilation valve 20, and the protection of the electronic components in the housing 10 is facilitated. The electrode 61 is disposed in the receiving space 212 of the valve body 21, and can detect the liquid flowing in from the first through hole 12 more accurately, because most of the liquid flowing in from the first through hole 12 flows into the receiving space 212.

In one embodiment, the housing 10 is provided with a sound outlet (not shown) for allowing the sound outputted from the speaker 90 to propagate to the outside of the housing 10. Some conventional electronic devices passively balance the internal and external air pressures simultaneously using the sound outlet of the speaker. The embodiment of the present invention actively balances the internal and external air pressure through the ventilation valve 20, and the air inside the housing 10 may flow into the outside of the housing 10 through the first through hole 12 or directly through the ventilation valve 20 (the first through hole 12 is omitted).

The present invention further provides a wearable electronic device, which includes the portable electronic device 100 and a connection portion, wherein the connection portion is connected with the housing 10, and the connection portion is used for detachably connecting the portable electronic device 100 to a preset target. For example, the wearable electronic device is a smart watch, and the connection portion is a wristband that connects the portable electronic device 100 to the wrist of the user.

Referring to fig. 14, the present invention further provides a control method of the portable electronic device 100, which includes the following steps:

step 101: monitoring whether an event meeting a preset condition occurs;

step 201: when an event meeting a preset condition occurs, the controller 30 of the portable electronic device 100 controls the ventilation valve 20 to be switched from the normally closed state to the open state so as to balance the air pressure inside and outside the housing 10.

According to the method, the portable electronic device can be configured to actively switch the air-permeable valve from the normally closed state to the open state, and air pressure balance between the inside and the outside of the portable electronic device can be achieved.

The portable electronic device, the wearable electronic device and the control method thereof disclosed in the embodiments of the present invention are described in detail, and specific examples are applied to the description of the principles and the implementation modes of the present invention, and the description of the above embodiments is only used for helping to understand the portable electronic device, the wearable electronic device, the control method and the core ideas of the present invention; meanwhile, as those skilled in the art will vary in the specific embodiments and application scope according to the idea of the present invention, the present disclosure should not be construed as limiting the present invention in summary.
