Description

TECHNICAL FIELD

[0001] The utility model relates to electronic equipment dehumidification technical field especially, relate to a kind of electronic humidity control device and electronic equipment. BACKGROUND

[0002] In order to better prolong service life, the closed sensitive electronic equipment shell often needs to open a vent hole in the shell, and "breathes". When the closed shell needs to meet a certain protection level, back adhesive type breathable film, welding type breathable film, air valve and other ways are usually used to block the ventilation, so as to ensure the micro-breathable and make the protection level of the shell meet the specific actual use requirements.

[0003] No matter back adhesive type breathable film, welding type breathable film, air valve and other ways, they can effectively balance the internal and external pressure difference of closed shell, prevent excessive condensation phenomenon, the main reason is that when the electronic equipment cools down, the negative pressure generated by the temperature reduction can be effectively compensated by waterproof breathable product, so that the closed shell always keeps the pressure inside and outside the shell in a balanced state, so that the external water vapor cannot be absorbed by the negative pressure formed by the system.

[0004] However, when the temperature of the system reaches room temperature, the entire sensitive electronic component system is in a natural balance state, that is, the temperature, humidity, pressure and other factors inside the shell are in a natural state. When the humidity outside is too large, such as a humid basement, plum rain season, rainy day, etc., the humidity inside the closed electronic component in such environment will reach the state of balance with the outside humidity, and if the moisture is condensed, the water droplets generated may damage the circuit board of sensitive electronic components.

[0005] To address similar issues, CN 215311347 U describes a dehumidification device for vehicle lights. This device includes a humidity sensor, an electrostatic dehumidifier, a desiccant, and a drive assembly. It primarily uses the drive assembly to control the sensor and electrostatic dehumidifier, working in conjunction with the desiccant to absorb water vapor inside the vehicle light, thereby ensuring dry air inside the light and reducing the likelihood of fogging. This can extend the lifespan of electronic components within the light and improve driving safety. A problem with this structure is that the electrostatic dehumidifier is directly connected to the outside environment, and since the dehumidifier itself also conducts moisture, when it is not working, it can actually increase the humidity inside the light. Patent CN 206890716 describes a photovoltaic integrated electrolyte membrane dehumidification air conditioning system. This system uses photovoltaic modules and a battery to continuously provide DC voltage to the electrostatic dehumidification system, effectively eliminating moisture inside the photovoltaic modules. A problem with this structure is that continuous operation of the electrolytic element can severely affect the lifespan of the membrane electrode in the electrostatic dehumidifier, thus impacting the lifespan of the entire assembly. This problem poses a significant challenge to the repair of electronic components located at high altitudes, remote mountainous areas, and will increase repair costs, necessitating improvements.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more understandable, the utility model will be described in further detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0036] Referring to Figures 3-14 The utility model discloses electronic humidity control device, including shell body 1, electrolytic dehumidifier 2, humidity sensor 3, humidity controller 4, air permeation membrane 5 and cover plate 6, wherein electrolytic dehumidifier 2, humidity sensor 3, humidity controller 4 and air permeation membrane 5 are all arranged in shell body 1. Figure 1 , Figure 2 As shown in the figure, when using, electronic humidity control device is fixed on the closed shell 7 of electronic equipment above.

[0037] The both sides in the shell body 1 are provided with dehumidification cavity 12 and through air permeation channel 16 respectively. The bottom entrance 11 is arranged at the bottom of the dehumidification cavity 12 of the shell body 1, to be used for the installation of electrolytic dehumidifier 2, and the first screw thread 111 is formed in the inner side wall of the bottom entrance 11, and the second screw thread 21 is formed in the outer side surface of electrolytic dehumidifier 2, and electrolytic dehumidifier 2 is screw-connected and installed in the bottom entrance 11. Therefore, electrolytic dehumidifier 2 and the shell body 1 are not only firmly installed, but also have the advantage of convenient disassembly. The membrane electrode is arranged in electrolytic dehumidifier 2, and the moisture formed by electrolysis of electrolytic dehumidifier 2 is discharged into the dehumidification cavity 12.

[0038] Referring to Figure 5 and Figure 6In order to enable the humidity sensor 3 and the humidity controller 4 to be firmly installed in the shell body 1, a first accommodating groove 13 and a second accommodating groove 14 are formed on one side surface of the shell body 1, so that a partition plate 18 is formed between the first accommodating groove 13 and the second accommodating groove 14. The humidity sensor 3 is arranged in the first accommodating groove 13 and is fixed to the shell body 1 by bolting, and the humidity controller 4 is arranged in the second accommodating groove 14 and is fixed to the shell body 1 by bolting. Thus, the humidity sensor 3 and the humidity controller 4 are not only firmly fixed to the shell body 1, but also are convenient to disassemble. The humidity sensor 3 is electrically connected to the humidity controller 4. The humidity controller 4 can be directly connected to an external DC power supply, or a battery or other power supply is integrated in the humidity controller 4 to supply power to the humidity controller 4. The humidity controller 4 can be a common humidity controller 4 on the market (for example, a humidity controller with a model number H6062). The humidity controller 4 controls whether to supply power to the electrolytic dehumidifier 2. The humidity sensor 3 continuously maintains a working state and can monitor the humidity inside the closed shell 7 at any time.

[0039] With reference to Figure 7 , Figure 8 and Figure 9 , an installation groove 15 is formed on the upper portion of the shell body 1. The air-permeable film 5 is installed in the installation groove 15 of the shell body 1, so that the air-permeable film 5 covers the upper portion of the dehumidification cavity 12 and the air-permeable passage 16. A through groove 17 is arranged on the upper portion of the shell body 1. A plurality of first support strips 171 are vertically arranged in the through groove 17. The top end surface of each first support strip 171 is flush with the bottom surface of the installation groove 15. A plurality of second support strips 121 are arranged on the inner side wall of the dehumidification cavity 12. The top end surface of each second support strip 121 is also flush with the bottom end surface of the installation groove 15. After the air-permeable film 5 is arranged in the installation groove 15, the air-permeable film 5 is lapped on the first support strips 171 and the plurality of second support strips 121, so as to avoid the phenomenon of collapse of the middle portion of the air-permeable film 5.

[0040] In order to enable the air-permeable film 5 to be stably positioned in the installation groove 15 of the shell body 1, a cover plate 6 is arranged on the upper portion of the shell body 1. A clamping plate 61 is arranged on the bottom end of the cover plate 6. The shape and size of the clamping plate 61 are matched with those of the installation groove 15. Exhaust holes 62 are formed on the surface of the cover plate 6 and the clamping plate 61. When the cover plate 6 is installed, the clamping plate 61 on one side of the cover plate 6 is clamped and installed in the installation groove 15 of the shell body 1, so that the clamping plate 61 presses the air-permeable film 5.

[0041] With reference to Figures 11-14The electrolytic dehumidifier 2 is electrically connected with the humidity controller 4, and the electrolytic dehumidifier 2 is controlled by the humidity controller 4 to enter the working state. When the electrolytic dehumidifier 2 is in the working state, the moisture on the anode side of the electrolytic dehumidifier 2 is electrolyzed to form hydrogen ions and oxygen, and then the hydrogen ions react with the oxygen in the air to form water vapor, so that the dehumidification purpose is achieved. The water vapor generated by the electrolytic dehumidification is discharged after passing through the air-permeable film 5. For the electrolytic dehumidifier 2, the air-permeable film 5 can effectively prevent the moisture absorbed by the membrane electrode in the dehumidification element from entering the inside of the sealed shell 7, that is, effectively block the electrolytic dehumidifier 2, and play a protective role for the dehumidification element.

[0042] In order to further balance the pressure difference between the inside and outside of the sealed shell 7, so as to prevent the sealed shell 7 from forming excessive negative pressure, causing the water vapor in the outside to enter the inside of the sealed shell 7 through the air-permeable film 5. The air-permeable passage 16 is vertically and throughly formed in the partition plate 18, and the air-permeable passage 16 penetrates the upper and lower ends of the shell body 1.

[0043] As shown in Figure 13 , Figure 14 , in order to avoid the water vapor formed by electrolysis in the dehumidification cavity from entering the air-permeable passage 16 and returning to the inside of the sealed shell 7 again, a sealing layer 51 is arranged at the bottom of the air-permeable film 5. The sealing layer 51 is arranged at least between the dehumidification cavity 12 and the air-permeable passage 16, so as to separate the dehumidification cavity 12 from the air-permeable passage 16. Figure 14 The sealing layer 51 is arranged between the dehumidification cavity 12 and the air-permeable passage 16, so as to separate the dehumidification cavity 12 from the air-permeable passage 16. Figure 13 The sealing layer 51 is arranged around the periphery of the dehumidification cavity 12 to seal the dehumidification cavity 12. The sealing layer 51 is a sealing ring or a sealing glue. When the sealing layer 51 is selected as the sealing glue, it is coated at the bottom of the air-permeable film 5. The air-permeable film 5 is fixedly adhered to the inner side of the periphery of the dehumidification cavity 12 by the sealing glue, so that the air-permeable passage 16 and the dehumidification cavity 12 are not communicated with each other, so as to avoid the water vapor from entering the air-permeable passage 16 from the dehumidification cavity 12. The arrangement of the air-permeable passage 16 has a better balancing effect on the pressure difference between the inside and outside of the sealed shell 7.

[0044] As shown in Figure 1 , Figure 2 , the utility model discloses an electronic equipment, including sealed shell 7 and electronic humidity control device, form the installation mouth 71 on the upper surface of sealed shell 7, and the electronic humidity control device is fixedly installed in installation mouth 71, and the electronic humidity control device plays the role of dehumidification to the electronic element in sealed shell 7. The electronic equipment can be a car lamp, a lithium battery pack, a stage lamp, a camera, an electronic camera, a power cabinet, an electrical control cabinet, a switch cabinet and the like which are sensitive to humidity.

[0045] Referring to Figure 10After the electronic humidity control device is installed in the installation port 71 of the closed shell 7, in order to make the electronic humidity control device be installed firmly at the installation port 71 of the closed shell 7. A plurality of installation portions 65 are arranged on the circumferential side of the cover plate 6, and a plurality of installation screw holes 63 are formed in the installation portions 65, and installation bolts 64 are screwed in each installation screw hole 63, and the installation bolts 64 are fixed on the installation port 71 of the closed shell 7.

[0046] The specific implementation principle of the utility model is: connecting the humidity controller 4 with the power supply, monitoring the humidity inside the closed shell 7 through the humidity sensor 3, transmitting the humidity value monitored by the humidity sensor 3 to the humidity controller 4, and the humidity controller 4 judges whether to provide flow voltage for the electrolytic dehumidifier 2 to control the electrolytic dehumidifier 2 to work.

[0047] Combining Figure 11 As shown in the figure, when it is detected that the humidity in the closed shell 7 is high (that is, greater than a certain humidity value), the humidity controller 4 controls the electrolytic dehumidifier 2 to enter the working state, and the electrolytic dehumidifier 2 effectively electrolyzes the humidity inside the closed shell 7, and discharges the humidity into the dehumidification cavity 12, and then discharges the water vapor into the atmosphere through the breathable film 5. When the humidity inside the closed shell 7 is low (that is, reduced to a certain humidity value), the humidity sensor 3 generates a signal again, and the humidity controller 4 disconnects the circuit of the electrolytic dehumidifier 2, and the electrolytic dehumidifier 2 stops working.

[0048] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, as long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, and the protection of the utility model is obtained.
