Description

Technical Field

[0001] The present application relates to the field of electronic devices, and in particular to a waterproof electronic device and a control method of the electronic device. Background Art

[0002] Electronic devices need to have certain waterproof and moisture-proof capabilities. However, due to cost considerations, most of the electronic devices currently on the market, represented by mobile phones, do not have high waterproof performance. Only special triple-proof mobile phones or high-end flagship phones are equipped with IP68 level protection. This is because the waterproof structure usually requires special sealing treatment of the interfaces in the electronic device through glue, such as earphones and USB interfaces, which require the use of glue dispensing and extrusion sealing rubber sleeves, or side buttons that require special silicone extrusion seals. As for the housings, panels, etc. of electronic devices, they generally require multiple glue dispensing seals or large-area foam glue seals to meet the waterproof requirements.

[0003] Furthermore, after the electronic device is assembled, a sealing test is required. This series of measures will result in a pass rate of electronic devices generally lower than 80%. The extensive use of glue will increase the cost of disassembly and maintenance of electronic devices, making rework extremely difficult. In addition, in the daily use of electronic devices, users may also encounter external impacts such as falling, and the aging of internal components of electronic devices after long-term use, which will also affect the long-term reliability of electronic devices, especially the reliability of waterproof design. Summary of the invention

[0004] This application proposes an electronic device with active waterproof capability, which avoids using too much glue inside the electronic device and improves the reliability of the electronic device. This application includes the following technical solutions:

[0005] An electronic device comprises a shell and a boosting device, a humidity sensor and a control device fixed in an inner cavity of the shell, wherein the shell is provided with at least one opening connected to the inner cavity, the humidity sensor is arranged corresponding to the opening and detects the humidity at the opening, the control device is electrically connected to the boosting device and the humidity sensor respectively, and the control device is configured to control the boosting device to inflate and boost the pressure of the inner cavity when the humidity sensor monitors that the humidity of the opening exceeds a preset humidity threshold.

[0006] Among them, the boosting device includes an air storage bin with an air outlet and an air replenishment port, and the boosting device also includes an air deflation mechanism arranged at the air outlet for controlling the air storage bin to inflate and pressurize the inner cavity, and an air replenishment mechanism connected to the air replenishment port for replenishing and pressurizing the air storage bin.

[0007] The deflation mechanism includes a sealing portion for sealing the air outlet, a first elastic member abutting against the sealing portion for providing sealing pressure, and a deflation portion abutting against the sealing portion in the opposite direction relative to the first elastic member to open the air outlet.

[0008] Wherein, the sealing portion is configured as a lever hinged on the gas storage bin, the first elastic member is configured as a compression spring arranged on a side of the sealing portion away from the gas storage bin, or,

[0009] The first elastic member is configured as a torsion spring that abuts against the sealing portion and the air storage bin at the same time.

[0010] Wherein, the deflation portion is constructed as a push rod slidably arranged on one side of the air storage bin.

[0011] Wherein, the air replenishing mechanism includes a piston part and a power source providing working power for the piston part.

[0012] Among them, the piston part includes a piston cavity connected to the air supply port and a piston rod slidably arranged in the piston cavity, and the piston cavity is also provided with a one-way air intake valve connected to the inner cavity. The power source drives the piston rod to reciprocate in the piston cavity to drive the piston rod to push the air entering the piston cavity from the one-way air intake valve into the air storage bin.

[0013] Wherein, a one-way check valve is provided between the piston cavity and the air supply port, and / or between the piston rod and the piston cavity, and the one-way check valve is used to prevent the air in the air storage bin from entering the piston cavity.

[0014] Wherein, the power source is a motor, and the motor drives the piston rod to reciprocate in the piston chamber through a screw mechanism.

[0015] Wherein, the deflation mechanism comprises a sealing portion for sealing the air outlet and a push rod for resisting the sealing portion to open the air outlet, and the push rod is fixed on the screw mechanism.

[0016] The present application also relates to a control method for an electronic device, which specifically comprises the following steps:

[0017] Determining that the humidity of the opening monitored by the humidity sensor exceeds a preset humidity threshold;

[0018] The boosting device is controlled to inflate and boost the pressure of the inner cavity of the electronic device.

[0019] Wherein, before determining that the opening humidity monitored by the humidity sensor exceeds a preset humidity threshold, the method further includes:

[0020] The boosting device is replenished with air to ensure that the boosting device meets the use standards.

[0021] After controlling the boosting device to inflate and boost the pressure of the inner cavity of the electronic device, the method further includes:

[0022] Determining that the humidity of the opening monitored by the humidity sensor is lower than a preset humidity threshold;

[0023] Control the boosting device to stop inflating. The electronic device described in the present application monitors the humidity at the opening position on the shell through a humidity sensor disposed in the inner cavity of the shell, and when the humidity at the opening position exceeds a preset humidity threshold, the control device drives the boosting device also fixed in the inner cavity to inflate the inner cavity, so that the pressure in the inner cavity can be higher than the pressure outside the shell, and prevents water vapor from further entering the inner cavity and causing damage to the electronic device. The electronic device control method described in the present application also adopts a principle similar to that of the electronic device of the present application, so that the electronic device and the control method of the present application both have the function of active boosting to achieve waterproofing. The electronic device of the present application achieves more convenient assembly and disassembly maintenance while ensuring its own waterproof performance, and can meet the reliability requirements for long-term use.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] See also Figure 1 The electronic device 100 shown includes a housing 101. A hollow inner cavity 102 is provided in the housing 101, and a boost device 10, a humidity sensor 20 and a control device 30 are fixedly provided in the inner cavity 102. Usually, a mainboard 104 and a battery 105 are also provided in the electronic device 100. In the electronic device 100 of the present application, the housing 101 is provided with at least one opening 103 that connects the inner cavity 102 to the outside of the housing 101, and the opening 103 can be an external interface of the electronic device 100, such as a USB interface, a Micro-USB interface, a TYPE-C interface, and an earphone interface. Alternatively, the opening 103 can also be used as a socket for a SIM card tray, a microphone port, a radio port, or even a key notch of the electronic device 100. The humidity sensor 20 is arranged at a position corresponding to the opening 103, and is used to monitor and obtain the humidity at the opening 103 in real time.

[0033] It is understandable that when there are multiple openings 103, the electronic device 100 may be provided with the same number of multiple humidity sensors 20, each humidity sensor 20 being used to monitor and obtain the humidity at one opening 103 in real time. When two or more openings 103 are located close to each other, only one humidity sensor 20 may be provided for the multiple openings 103 located close to each other to simultaneously sense and obtain the humidity of the multiple openings 103. The electronic device 100 of the present application is not particularly limited to this.

[0034] Further, the control device 30 can be set as a separate control element, or a processor mounted on the mainboard 104 of the electronic device 100 can be used as the control device 30. The control device 30 is electrically connected to the boost device 10 and the humidity sensor 20 respectively. The control device 30 is configured to receive the humidity at the corresponding opening 103 obtained by the humidity sensor 20. The control device 30 is also configured to determine whether the humidity is greater than a preset humidity threshold after receiving the humidity, that is, the control device 30 determines the magnitude relationship between the humidity and the humidity threshold preset in the control device 30 after receiving the humidity. When the control device 30 determines that the humidity at the opening 103 obtained by the humidity sensor 20 exceeds the humidity threshold preset in the control device 30, the control device 30 controls the boost device 10 to inflate the inner cavity 102 to increase the pressure in the inner cavity 102.

[0035] It can be understood that the humidity threshold preset in the control device 30 can correspond to the scene where the humidity in the environment where the electronic device 100 is located exceeds the standard. When the electronic device 100 is in a normal working environment, the humidity obtained by the humidity sensor 20 is not greater than the humidity threshold preset in the control device 30, and the booster device 10 is in a non-working state. When water vapor infiltrates the opening 103, or the opening 103 is immersed in water, the humidity at the opening 103 obtained by the humidity sensor 20 will be greater than the humidity threshold preset in the control device 30. At this time, the control device 30 triggers the active waterproof protection mechanism, controls the booster device 10 to release the high-pressure gas stored in the inner cavity 102, and then increases the pressure in the inner cavity 102, so that the pressure in the inner cavity 102 is higher than the pressure outside the housing 101, especially higher than the external pressure at the opening 103, thereby blocking water vapor or water from further entering the interior of the electronic device 100 from the opening 103, and preventing the interior of the electronic device 100 from being damaged by water vapor. When the humidity at the opening 103 acquired by the humidity sensor 20 is not greater than the humidity threshold, the boosting device 10 is in a non-working state and stops inflating the inner cavity 102 .

[0036] The electronic device 100 of the present application forms a protective mechanism for triggering its own active waterproofing based on the real-time humidity obtained by the humidity sensor 20 through the setting of the above scheme. The boosting device 10 is driven by the control device 30 to inflate the inner cavity 102 to increase the pressure in the inner cavity 102, thereby achieving the effect of blocking external water vapor or water from invading the inner cavity 102. The electronic device 100 of the present application thus has waterproof performance, and the implementation of the above scheme does not require too much glue, rubber sleeves and other waterproof structures to be set inside the electronic device 100, which also simplifies the difficulty of installation, disassembly and maintenance of the electronic device 100, and can improve the product yield. Furthermore, the electronic device 100 of the present application also avoids the defects of colloid aging and reduced sealing performance after long-term use due to the use of too much glue, rubber sleeves and other waterproof structures. The electronic device 100 of the present application has a longer service life and better sealing reliability.

[0037] It should be pointed out that the problem of reduced sealing performance caused by colloid aging after long-term use inside the electronic device 100 may not only exist at the position where the shell 101 is provided with the opening 103. In some non-opening positions outside the shell 101 that are sealed by bonding and clamping, gaps may also be formed due to aging or deformation after long-term use. When the humidity of the environment outside the electronic device 100 is relatively high, these gaps may also be invaded by water vapor. At this time, because the humidity sensor 20 is provided inside the electronic device 100, the active waterproof protection mechanism of the electronic device 100 can also be triggered after the humidity in the inner cavity 102 exceeds the standard. The high-pressure gas released by the booster device 10 is filled in various areas of the inner cavity 102, so it can also increase the internal pressure of the above-mentioned gap position and be higher than the external environmental pressure, thereby preventing water vapor from entering the inner cavity 102, and also protecting the electronic device 100 from water vapor.

[0038] The opening 103 of the electronic device 100 usually has a certain sealing structure, at least to meet the dustproof requirements. Therefore, water vapor can usually only penetrate into the inner cavity 102 through the partial gap at the opening 103. The gaps formed by aging or deformation of the electronic device 100 are usually small, and it is difficult for water vapor to enter a large area. Therefore, the boosting device 10 does not need to continuously perform large-volume deflation operations to inflate and boost the inner cavity 102. This is beneficial for the electronic device 100 of the present application to control the overall volume of the boosting device 10. It only needs to provide the inner cavity 102 with a stable pressure higher than the external environment for a certain period of time, so as to better achieve the active waterproof effect of the present application.

[0039] The electronic device 100 can be any device with communication and storage functions, such as: tablet computers, mobile phones, e-readers, remote controls, personal computers (PCs), laptops, car equipment, Internet TVs, wearable devices and other smart devices with network functions.

[0040] For an example, see Figure 2-Figure 4 Schematic diagram. In order to realize the function of storing and releasing compressed gas, the boosting device 10 includes an air storage bin 11, an air release mechanism 12 and an air replenishing mechanism 13. Specifically, the air storage bin 11 needs to have an air outlet 111 and an air replenishing port 112. The air release mechanism 12 is arranged corresponding to the air outlet 111 and is used to control the air storage bin 11 to complete the inflation and pressurization of the inner cavity 102. The air replenishing mechanism 13 is connected to the air replenishing port 112 and is used to replenish and pressurize the air storage bin 11. It can be understood that the pressure of the gas stored in the air storage bin 11 needs to be higher than the pressure of the inner cavity 102 and the external environment, that is, higher than the atmospheric pressure. Therefore, between the air release mechanism 12 and the air outlet 111, and between the air replenishing mechanism 13 and the air replenishing port 112, higher sealing conditions are required to meet the air release needs of the electronic device 100 during active sealing.

[0041] In one embodiment, the deflation mechanism 12 includes a sealing portion 121, a first elastic member 122, and a deflation portion 123. The shape of the sealing portion 121 is matched with the shape of the air outlet 111, and the sealing portion 121 is used to seal the air outlet 111. The first elastic member 122 is used to resist the sealing portion 121 and provide pressure for the sealing portion 121 to seal the air outlet 111. It can be understood that the pressure provided by the first elastic member 122 to the sealing portion 121 needs to be greater than the pressure of the gas stored in the gas storage bin 11. The deflation portion 123 functionally needs to provide a force that is opposite to the pressure of the first elastic member 122 acting on the sealing portion 121, which is used to release the sealing fit between the sealing portion 121 and the air outlet 111. Or it can be described as that the deflation portion 123 resists the sealing portion 121 in the opposite direction relative to the first elastic member 122, and is used to open the seal of the sealing portion 121 on the air outlet 111.

[0042] The deflation portion 123 is usually required to be movably arranged, especially slidably arranged in the inner cavity 102, and does not contact the sealing portion 121 when the electronic device 100 does not activate the active protection mechanism, and pushes the sealing portion 121 open by moving, especially sliding, in the inner cavity 102 when waterproof inflation is required. To this end, the sealing portion 121 can be constructed as a lever structure hinged on the gas storage bin 11, and the first elastic member 122 provides pressure toward the air outlet 111 to the sealing portion 121 constructed as a lever structure to drive the sealing portion 121 to form a seal with the air outlet 111. In the illustrated embodiment, the first elastic member 122 is further constructed as a compression spring arranged on the side of the sealing portion 12 away from the gas storage bin 11, one end of the first elastic member 122 abuts against the fixed surface in the inner cavity 102, and the other end of the first elastic member 122 abuts against the sealing portion 121 to provide pressure for the sealing portion 121 to form a seal with the air outlet 111. In other embodiments, the first elastic member 121 may also be constructed as a torsion spring structure that abuts against the sealing portion 121 and the gas storage bin 11 at the same time. The first elastic member 122 constructed as a torsion spring structure may be sleeved at the rotation fulcrum position of the sealing portion 121 constructed as a lever structure, and one end of the torsion arm of the first elastic member 122 abuts against the sealing portion 121, and the other end of the torsion arm abuts against the gas storage bin 11, providing pressure for the two to move toward each other, thereby achieving the effect of driving the sealing portion 121 to seal the gas outlet 111.

[0043] Furthermore, the deflation part 123 is constructed as a push rod structure slidably connected to one side of the gas storage bin 11. One end of the sealing part 121 constructed as a lever structure is connected to the gas storage bin 11, and the other end thereof extends toward the side of the gas storage bin 11 where the deflation part 123 is provided. When the deflation part 123 is in a non-working state, it does not contact the extended end of the sealing part 121 (see Figure 2), and when the humidity obtained by the humidity sensor 20 exceeds the preset humidity threshold and triggers the control device 30 to start the active waterproof mechanism, the control device 30 drives the air release portion 123 to slide toward the end of the sealing portion 121, and continuously presses against the end of the sealing portion 121 to overcome the pressure applied by the first elastic member 122 to the sealing portion 121, so that the sealing portion 121 rotates relative to the air storage bin 11 and releases the sealed connection between the sealing portion 121 and the air outlet 111 (see Figure 3 ). At this time, the compressed gas stored in the gas storage bin 11 can enter the inner cavity 102 and increase the pressure in the inner cavity 102, thereby achieving the effect of preventing water vapor from entering the electronic device 100.

[0044] In another embodiment, the deflation mechanism 12 can also be configured as a solenoid valve (not shown) electrically connected to the control device 30. The deflation mechanism 12 configured as a solenoid valve is in a state of sealing the gas outlet 111 in a non-pressurized scenario, and when the inner cavity 102 needs to be inflated and pressurized, the control device 30 controls the deflation mechanism 12 configured as a solenoid valve to open, so that the high-pressure gas in the gas storage bin 11 is filled into the inner cavity 102, which can also achieve the effect of controlling the sealing and deflation of the gas storage bin 11 similar to the above scheme.

[0045] In one embodiment, the air replenishment mechanism 13 connected to the air replenishment port 112 of the boosting device 10 includes a piston part 131 and a power source 132, wherein the power source 132 provides the piston part 131 with working power for replenishing air in the air storage bin 11, and the piston part 131 pushes gas from the air replenishment port 112 into the air storage bin 11 through piston movement to maintain the air pressure in the air storage bin 11. The power source 132 is electrically connected to the control device 30, and the control device 30 is also configured to control the power source 132 to drive the piston part 131 to replenish air. Specifically, a pressure measuring device (not shown) can also be set in the air storage bin 11 to detect the air pressure value in the air storage bin 11 in real time. The pressure measuring device is also electrically connected to the control device 30, and the control device 30 can preset the air pressure parameters corresponding to the air storage bin 11. When the control device 30 receives the air pressure value in the air storage bin 11 from the pressure measuring device and it is lower than the preset air pressure parameters, the air replenishing mechanism 13 is controlled to replenish air and pressurize the air storage bin 11 from the air replenishing port 112.

[0046] The control device 30 can also control the air replenishing mechanism 13 to replenish and pressurize the air storage bin 11 after the boosting device 10 completes the active waterproof action each time, or after the electronic device 100 is used for a fixed time, to ensure that the air storage bin 11 is in a high-pressure state at any time. On the other hand, because the positions of the openings 103 or the gaps on the housing 101 where water vapor intrudes each time are different, the amount of air released by the air storage bin 11 to inflate and pressurize the inner cavity 102 each time is also different. The control device 30 can also calculate the remaining air pressure in the air storage bin 11 by monitoring the working time of the deflation mechanism 12 each time, and control the air replenishing mechanism 13 to replenish the air storage bin 11 according to the remaining air pressure. In one embodiment, the control device 30 can also calculate the remaining air pressure in the air storage bin 11 by the air pressure value in the air storage bin 11 measured by the pressure measuring device, and control the air replenishing mechanism 13 to replenish the air storage bin 11 according to the remaining air pressure.

[0047] In one embodiment, the piston portion 131 includes a piston cavity 1311 connected to the air supply port 112 and a piston rod 1312 slidably disposed in the piston cavity 1311. The piston rod 1312 reciprocates in the piston cavity 1311 to achieve the function of continuously feeding gas to the air supply port 112. The piston cavity 1311 needs to be provided with a one-way air intake valve 1313 connected to the inner cavity 102, so as to cooperate with the reciprocating motion of the piston rod 1312 to suck the air in the inner cavity 102 into the piston cavity 1311.

[0048] The reciprocating motion of the piston rod 1312 in the piston cavity 1311 is driven by the power source 132. In the diagram, the power source 132 is configured as a combination of a motor 1321 and a lead screw mechanism 1322. The motor 1321 is fixedly connected to the inner cavity 102, and the lead screw mechanism 1322 is movably connected between the motor 1321 and the piston rod 1312, that is, the motor 1321 drives the piston rod 1312 through the lead screw mechanism 1322. The motor 1321 is electrically connected to the control device 30, and the control device 30 drives the motor 1321 to rotate forward and reverse periodically, thereby controlling the lead screw mechanism 1322 to drive the piston rod 1312 to reciprocate relative to the piston cavity 1311.

[0049] Specifically, when the control device 30 drives the motor 1321 to rotate forward, the lead screw mechanism 1322, driven by the motor 1321, drives the piston rod 1312 from the piston chamber 1311 to the far end of the gas replenishment port 112 (see Figure 2 ) moves to the proximal end (i.e., the end where the piston chamber 1311 is connected to the gas supply port 112) (see Figure 4), at this time, the one-way air intake valve 1313 provided on the piston cavity 1311 is in a one-way closed state, and the piston rod 1312 pushes the air in the piston cavity 1311 from the air replenishing port 112 into the air storage bin 11, thereby completing the air replenishing operation for the air storage bin 11. When the control device 30 drives the motor 1321 to reverse, the lead screw mechanism 1322 drives the piston rod 1312 from the proximal end of the piston cavity 1311 to the distal end under the drive of the motor 1321, at this time, the one-way air intake valve 1313 provided on the piston cavity 1311 is in a one-way open state, and the piston rod 1312 can inhale air from the inner cavity 102 through the one-way air intake valve 1313 to replenish the air into the piston cavity 1311. Thus, the air replenishing operation of the air replenishing mechanism 13 for the air storage bin 11 is completed through the periodic forward and reverse control of the motor 1321 by the control device 30.

[0050] In one embodiment, in order to prevent the gas in the gas storage bin 11 from entering the piston chamber 1311 when the piston rod 1312 moves from the proximal end to the distal end of the piston chamber 1311 to inhale, a one-way check valve 133 is further provided between the piston chamber 1311 and the gas replenishment port 112. The one-way check valve 133 only allows air to enter the gas storage bin 11 from one side of the piston chamber 1311 through the gas replenishment port 112, and prevents the gas in the gas storage bin 11 from entering one side of the piston chamber 1311. At the same time, a one-way check valve 133 or a similar valve structure may also be provided between the piston rod 1312 and the piston chamber 1311. In this case, the one-way check valve 133 or a similar valve structure is used to prevent air leakage between the piston rod 1312 and the piston chamber 1311, thereby improving the working efficiency of the gas replenishment mechanism 13.

[0051] In one embodiment, a second elastic member 134 may be sleeved on the piston rod 1312, and the screw mechanism 1322 compresses the second elastic member 134 to a certain compression amount and then pushes the piston rod 1312 through the second elastic member 134 when driving the piston rod 1312 to reciprocate. Such a setting can adjust the air pressure replenishment size and speed of the air replenishment mechanism 13 through the second elastic member 134, and at the same time, the pressure of the gas replenished in the air storage bin 11 is also higher than the air pressure in the inner cavity 102.

[0052] In one embodiment, since the piston rod 1312 performs linear reciprocating motion relative to the inner cavity 102, the deflation part 123 configured as a push rod also performs reciprocating motion relative to the inner cavity 102, and the two have the same motion mode. And by adjusting the placement of the piston part 131 in the inner cavity 102, the motion direction of the piston rod 1312 can be made the same as the motion direction of the deflation part 123 configured as a push rod. Therefore, the deflation part 123 can also be arranged on the screw mechanism 1322 and fixedly connected to the screw mechanism 1322. At this time, the screw mechanism 1322 can act to drive the piston rod 1312 to perform reciprocating motion in the piston cavity 1311 to replenish the air storage bin 11, and at the same time act to drive the deflation part 123 to press against the end of the sealing part 121 extending out to open the air outlet 111. That is, the motor 1321 can provide power for the air replenishment mechanism 13 and the deflation mechanism 12 at the same time. Such a configuration can simplify the internal structure of the electronic device 100 of the present application and reduce the volume occupied by the boost device 10 .

[0053] It should be pointed out that, because the piston rod 1312 and the deflation part 123 are both driven by the screw mechanism 1322 and respectively complete the actions of replenishing and deflation, it is advisable to control the movement stroke of the piston rod 1312 to be smaller than the movement stroke of the deflation part 123. That is, when the piston rod 1312 reciprocates in the piston chamber 1311 to replenish the gas storage bin 11, the deflation part 123 will not abut against the end of the sealing part 121 extending out and cause the deflation action of the gas storage bin 11; and when the control device 30 needs to control the deflation mechanism 12 to deflate, the rotation angle of the motor 1321 driven to deflate is greater than the rotation angle of the piston rod 1312 driven to replenish, so that the deflation part 123 further moves toward the end of the sealing part 121 extending out and abuts to open the deflation port 111. The control device 30 drives the motor 1321 to rotate at different angles during air replenishment and air deflation, respectively. This can be achieved through the driver program of the control device 30, or by setting a position sensor (not shown in the figure) in the piston chamber 1311 to sense the movement position of the piston rod 1312 and stop the further rotation of the screw mechanism 1322 in time.

[0054] Therefore, see Figure 5As shown in the figure, the electronic device 100 of the present application specifically needs to perform a system initialization process in the whole process of the active waterproof solution, and then control the air replenishment mechanism 13 in the boosting device 10 to inflate the air storage bin 11, until the air pressure in the air storage bin 11 reaches the use standard, and then turn on the humidity sensing function of the humidity sensor 20. Then, when the humidity obtained by the humidity sensor 20 is greater than the humidity threshold preset in the control device 30, the control device 30 triggers the active waterproof protection mechanism, controls the boosting device 10 to release the high-pressure gas stored in the inner cavity 102, and quickly increases the pressure in the inner cavity 102, so that the pressure in the inner cavity 102 is higher than the external environmental pressure, and blocks water vapor or water from further entering the interior of the electronic device 100. At this time, the humidity sensor 20 continues to perform the humidity sensing work in the inner cavity 102, and after the humidity in the inner cavity 102 is lower than the preset humidity threshold, the boosting device 10 stops the inflating action of the air storage bin 11, and can also synchronously drive the air replenishment mechanism 13 to replenish the air storage bin 11 to cope with the subsequent possible active waterproof action.

[0055] Based on the above process, this application also provides a control method for an electronic device. Figure 6 , this method specifically comprises the following steps:

[0056] S10, determining that the humidity of the opening 103 monitored by the humidity sensor 20 exceeds a preset humidity threshold;

[0057] S20 , controlling the boosting device 10 to inflate and boost the pressure of the inner cavity 102 of the electronic device 100 .

[0058] Specifically, the method uses the humidity sensor 20 to monitor the humidity of the opening 103, and can obtain the humidity information at the opening 103 in real time. After determining that the humidity of the opening 103 exceeds the preset humidity threshold, the boosting device 10 is immediately started to inflate the inner cavity 102 of the electronic device 100, so that the air pressure in the inner cavity 102 is higher than the external air pressure, thereby preventing water vapor from penetrating into the electronic device 100, thereby achieving the function of controlling the active waterproofing of the electronic device 100.

[0059] For an example, see Figure 7 Before step S10 "determining that the humidity of the opening 103 monitored by the humidity sensor 20 exceeds a preset humidity threshold", the method may further include:

[0060] S9. Replenish air to the boosting device 10 to ensure that the boosting device 20 meets the use standard.

[0061] That corresponds to Figure 5The booster device 10 needs to be filled with gas first, so that the gas pressure stored in the booster device 10 reaches the use standard, so that when the booster device 10 is started, it can ensure that it can inflate the inner cavity 102 and make the gas pressure in the inner cavity 102 higher than the external air pressure.

[0062] In one embodiment, after step S20 of “controlling the boosting device 10 to inflate and boost the pressure of the inner cavity 102 of the electronic device 100”, the method further includes:

[0063] S30, determining that the humidity of the opening 103 monitored by the humidity sensor 20 is lower than a preset humidity threshold;

[0064] S40, controlling the boosting device 10 to stop charging.

[0065] Specifically, the humidity sensor 20 continuously detects the humidity of the opening 103, and whether the boosting device 10 inflates the inner cavity 102 does not affect the monitoring work of the humidity sensor 20. At the same time, the boosting device 10 can also continuously inflate and boost the inner cavity 102, and it is necessary to ensure that after the electronic device 100 leaves the environment with high humidity, the humidity at the opening 103 is lower than the preset humidity threshold, and the boosting device 10 can stop the inflation work, so that the pressure of the inner cavity 102 returns to normal.

[0066] It is understandable that after the method completes an active air replenishment action, the humidity sensor 20 can continue to monitor the humidity of the opening 103 and replenish air to the boost device 10 at the same time to deal with the next time it is determined that the humidity of the opening 103 exceeds the preset humidity threshold.

[0067] The control method of the electronic device 100 of the present application can also be developed based on the various implementations of the electronic device 100 described above, which will not be described one by one here.

[0068] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
