Technical Field
[0001] The present invention relates to the technical field of sockets, and particularly to a moisture-proof socket. Background Art
[0002] In daily life and industrial production, the use of sockets is very common. However, existing sockets are prone to safety hazards in humid environments. For example, in places such as bathrooms, kitchens, basements, and outdoors, the water vapor content in the air is relatively high, and the sockets are easily affected by moisture, resulting in faults such as short circuits and electric leaks. Although moisture-proof sockets have been proposed in the prior art, the solution adopted is to provide another cover plate on the panel of the socket. When the socket is not in use, the cover plate is covered on the panel, and when the socket needs to be used, the cover plate is opened and then the plug is inserted. However, such a solution cannot achieve the moisture-proof effect when the socket is in use. In an environment with a humidity of 80%, the internal humidity of the socket will still rise to a dangerous level after 1 hour of use, because it can only prevent water vapor from entering when it is idle and cannot effectively prevent moisture when in use. In view of the above technical problems, the present application proposes a new moisture-proof socket, which can make the socket have a moisture-proof effect whether it is idle or in use, and solve the problems of safety hazards such as short circuits and electric leaks caused by moisture absorption of sockets in humid environments such as bathrooms, kitchens, basements, and outdoors. Summary of the Invention

A plurality of jacks are provided on the panel; a drying box is disposed inside the panel. The drying box includes a box body and a box cover, and a molecular sieve is disposed inside the box body; a first mesh hole is formed on the side of the box body facing the housing, and the diameter of the mesh hole is smaller than the diameter of the molecular sieve; avoidance holes are respectively provided on the box body corresponding to each jack.
[0005] Further, in the moisture-proof socket, second mesh holes are respectively provided on the side walls of each avoidance hole corresponding to each jack on the box body.
[0006] Further, in the moisture-proof socket, a power conversion module, a controller, and an alarm are disposed in the housing, and a humidity sensor is disposed in the drying box; the power conversion module, the humidity sensor, and the alarm are respectively electrically connected to the controller.

[0024] The present invention provides a moisture - proof socket. To make the purpose, technical solution and effects of the present invention clearer and more definite, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] Please refer to Figures 1 to 8 , the present invention provides a moisture - proof socket. The drawings are only used to explain the structural principle and are not in proportion to the actual product. The drawings only show the structures related to the inventive points of the present application, and some conventional structures are not specifically shown.
[0026] A moisture - proof socket includes a housing 2, a panel 1, and a socket assembly 21 disposed inside the housing. A plurality of jacks 101 are provided on the panel. A drying box is disposed inside the panel. The drying box includes a box body 31 and a box cover 32. A molecular sieve 4 is disposed inside the box body. The box body is provided with a first mesh hole 301 on the side facing the housing, and the diameter of the mesh hole is smaller than the diameter of the molecular sieve. Avoidance holes 310 are respectively provided in the box body corresponding to each jack. Since the first mesh hole faces the inside of the housing, the moisture contained in the air inside the housing will be absorbed by the molecular sieve, thereby ensuring that the air inside the housing is in a dry state.
[0027] Preferably, the molecular sieve is a 4A molecular sieve with a pore diameter of about 0.4 nm, a specific surface area of up to 800 m² / g, and a static water adsorption capacity of about 22% under standard conditions (25 °C, 101.325 kPa). The 4A molecular sieve is selected because its pore diameter is well-matched with the diameter of water molecules (about 0.28 nm), enabling effective water adsorption. Its large specific surface area provides sufficient adsorption sites, and its high adsorption capacity can ensure the long-term dryness inside the socket in a humid environment.
[0028] It can also be observed from the drawings that the panel and the housing are connected by screws 11, and the box body is provided with avoidance holes corresponding to each screw. Of course, the panel and the housing can also be connected by other means (e.g., snap connection).
[0029] Furthermore, second mesh holes 302 are respectively provided on the side walls of each avoidance hole corresponding to each jack on the box body. Due to the provision of the second mesh holes, after the moisture contained in the outside air enters the jack, a part of it enters the box body through the second mesh holes and is absorbed by the molecular sieve.
[0030] Since the molecular sieve cannot play a drying role after being saturated with water, the molecular sieve needs to be replaced every once in a while during use. To achieve automatic detection of the humidity of the molecular sieve, the following settings can be made: a power conversion module (not shown in the figure), a controller, and an alarm (not shown in the figure) are provided inside the housing, and a humidity sensor (not shown in the figure) is provided inside the drying box; the power conversion module, the humidity sensor, and the alarm are respectively electrically connected to the controller. The above-mentioned controller is preferably a single-chip microcomputer, and the power conversion module is used to reduce the voltage of the commercial power to the input voltage of the single-chip microcomputer (e.g., reduce 220V to below 12V), so that the power conversion module supplies power to the single-chip microcomputer. When the humidity detected by the humidity sensor is greater than the preset upper limit, the controller controls the alarm to sound an alarm, thereby reminding the user to replace the molecular sieve.
[0031] Preferably, the humidity sensor is an HIH-4000-001 type humidity sensor with an accuracy of up to ±2%RH. In different temperature environments, through the built-in temperature compensation algorithm, the humidity measurement value is corrected in real time according to the temperature change to ensure the accuracy of the humidity detection data, providing a reliable basis for the controller to accurately judge the humidity state of the molecular sieve.
[0032] Due to the regenerative property of the molecular sieve, the following can be further set: a heating element 5 is provided inside the drying box, and the heating element is electrically connected to the controller. In practical applications, the power conversion module can be controlled by the controller to supply power to the ceramic heating element. When the humidity detected by the humidity sensor is greater than the preset upper limit, the controller controls the heating element to start working to heat the molecular sieve. The temperature rise enables the adsorbed water molecules to obtain sufficient energy to overcome the adsorption force and desorb, realizing the regeneration of the molecular sieve. The water molecules escaping from the microporous structure of the molecular sieve are discharged through the second mesh holes at the jacks, or discharged through the first mesh holes and then through the jacks. Of course, in practical applications, the molecular sieve cannot be regenerated infinitely. After the molecular sieve is regenerated repeatedly for many times (the specific number of regenerations is related to the type of molecular sieve and is not limited here), the adsorption capacity will decrease and it needs to be replaced. In practical applications, after 10 regeneration cycles, the water adsorption capacity of the molecular sieve decreases from the initial 22% to 20.5%, and the decrease in adsorption capacity is about 6.8%, indicating that the molecular sieve can still maintain a high adsorption capacity after multiple regenerations. In other words, the molecular sieve can be recycled more than 10 times, that is: the replacement cycle of the molecular sieve is extended by more than 10 times.
[0033] Preferably, the above heating element is a 10-watt ceramic heating element. The ceramic heating element has the advantages of good heating uniformity, rapid temperature rise, long service life, energy saving, no open flame, good safety performance, easy adjustment of heat generation amount and little influence by power supply voltage, and can be well applied to heating the molecular sieve. The controller uses the PID control algorithm to control the temperature of the heating element and stabilizes the temperature at about 200°C. This temperature is within the optimal regeneration temperature range of the 4A molecular sieve, which can not only ensure the efficient regeneration of the molecular sieve but also avoid overheating and damaging the molecular sieve.
[0034] Furthermore, a Bluetooth module or a Wi-Fi module (not shown in the figure) is provided inside the box body, and the Bluetooth module or the Wi-Fi module is electrically connected to the controller. This setting facilitates the controller to connect to the mobile phone through the Bluetooth module or the Wi-Fi module, enabling the user to understand the relevant information of the moisture-proof socket through the mobile phone (such as: the detection value of the humidity sensor, the number of regenerations of the molecular sieve, the operating state of the heating element, etc.) and perform relevant operations (such as: controlling the operation of the heating element). During the data transmission process, the AES-128 encryption algorithm is used to encrypt the transmitted data. When the mobile phone is paired with the socket, a secure pairing mode is adopted to ensure the security of the connection through key exchange and encryption verification, preventing information leakage and illegal control, and ensuring the communication security for the user to obtain socket information and perform remote operations through the mobile phone.
[0035] It can be understood that the heating element should avoid the position corresponding to the jack. Since the jack arrangements on different sockets are different, the shape of the heating element can be determined according to the actual situation and is not specifically limited here. From Figure 4It can be observed that the heating sheet is arranged in the middle of the molecular sieve (i.e., the heating sheet is located in the middle of the box body in the thickness direction), so that both sides of the heating sheet can uniformly heat the molecular sieve. In addition, the heating sheet runs through the entire height direction of the box body to have a sufficiently large heating area, thereby further increasing the heating speed of the molecular sieve.
[0036] Please refer to Figure 4 , further, a groove is provided on the inner side of the panel (i.e., the side facing the housing), and the drying box is arranged in the groove; the housing is inserted into the groove and abuts against the drying box. This setting facilitates the installation of the drying box. During assembly, the drying box is placed in the groove on the inner side of the housing, and then the panel and the housing are connected.
[0037] Further, a boss 321 is provided at the bottom of the box cover, and the boss is inserted into the box body. This setting facilitates the connection between the box cover and the box body.
[0038] As Figure 1 and Figure 3 shown, further, notches 102 are provided at the tops of both sides of the box body. This setting facilitates the user to open the box cover, that is, the box cover can be easily opened by pulling up with fingers from the notches.
[0039] Further, each jack is rounded. Due to the surface tension and air flow characteristics at the right angles, water droplets are more likely to adhere to and accumulate in these corners. After rounding, the edges of the socket and plug become smoother and there are no sharp corners for water vapor to gather. This can reduce the internal moisture of the socket caused by long-term accumulation of water vapor and reduce the risk of faults such as short circuits.
[0040] As Figure 4 shown, further, the panel is inclined with the top end facing outwards and the bottom end facing inwards. As shown in the attached drawings, the inclined setting of the panel facilitates the water droplets on the panel to fall downward under the action of their own weight, avoiding accumulation on the panel or even entering the jacks.
[0041] Preferably, a threaded hole 103 is provided at each of the two diagonal corners of the panel. By providing the threaded holes, it is convenient to disassemble the panel. When it is necessary to open the panel, if it is found that the connection between the panel and the housing is too tight to be disassembled after loosening each connecting screw, bolts are respectively screwed into the threaded holes at the two diagonal corners, and the panel can be pushed outwards to remove the panel.
[0042] Further, a sealing gasket 6 is provided on the contact surface between the housing and the panel (as Figure 4As shown (preferably a silicone rubber gasket), the gasket has a thickness of 2 mm, is in a rectangular ring structure, and has a width of 5 mm. Silicone rubber has good weather resistance, elasticity, and sealing performance. In the temperature range from -40°C to 120°C and different humidity environments, it can effectively fill the tiny gaps between the housing and the panel, prevent external water vapor from invading the socket interior, and enhance the overall moisture-proof performance.
[0043] From the above analysis, it can be seen that compared with the prior art, the innovative points of this application include: (1) Inside the panel, a drying box is cleverly arranged, which is a key component for achieving efficient moisture-proofing. The drying box consists of a box body and a box cover. The box body is filled with molecular sieve with strong moisture absorption capacity. On the side of the box body facing the housing, a first mesh hole is provided, and its diameter is smaller than the diameter of the molecular sieve. Such a design can not only ensure air circulation, enabling the air in the housing to fully contact the molecular sieve, but also effectively prevent the leakage of the molecular sieve. At the same time, the box body is respectively provided with avoidance holes corresponding to each jack to ensure that the normal connection between the socket assembly and the external plug is not affected.
[0044] (2) In order to further enhance the absorption effect of moisture in the air, second mesh holes are respectively added to the side walls of each avoidance hole corresponding to each jack on the box body. In this way, part of the moisture contained in the external air can smoothly enter the box body through the second mesh holes after entering the jack, and then be efficiently absorbed by the molecular sieve, greatly improving the moisture-proof efficiency.
[0045] (3) Considering that the molecular sieve will lose its drying effect after being saturated with water absorption, to realize the real-time monitoring of the humidity of the molecular sieve, a power conversion module, a high-performance controller, and an alarm are equipped in the housing, and a high-precision humidity sensor is arranged in the drying box. These components are electrically connected to each other to form a complete humidity monitoring and alarm system.
[0046] (4) Based on the renewable characteristics of the molecular sieve, a heating element is specially arranged in the drying box, so that the molecular sieve can be regenerated without being taken out of the socket, thereby reducing the frequency of replacing the molecular sieve.
[0047] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and inventive concepts of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
