[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0032] like Figures 1 to 4 As shown, an electronic humidity control device in one embodiment of the present invention includes a housing 1, a circuit board 2, a knob cap 3, and a cable 4.
[0033] Preferably, the outer shell 1 has a length of 104mm, a width of 76mm, and a height of 36mm.
[0034] The outer shell 1 includes a lower shell 101 and an upper shell 102, and a plurality of first connecting screws 103 are connected between the lower shell 101 and the upper shell 102. The plurality of first connecting screws 103 are used to fix the lower shell 101 and the upper shell 102 through mutual cooperation.
[0035] Preferably, the lower housing 101 is provided with a label for indicating relevant data of the circuit board 2, including the serial number of the circuit board 2 and the rated voltage, such as the rated voltage of the circuit board 2 being 220V.
[0036] In addition, the surface of the upper shell 102 is provided with an indicator scale groove, which corresponds to the knob cap 3, so that the user can know the rotation angle of the knob cap 3 in order to set the dehumidification humidity value, and at the same time improve the adjustment accuracy.
[0037] Specifically, a pair of side sealing plates 104 are connected between the lower shell 101 and the upper shell 102. The pair of side sealing plates 104 are symmetrically arranged on both sides of the lower shell 101, and the side sealing plates 104 play a sealing role.
[0038] In addition, one of the side sealing plates 104 is provided with a through hole 1041 to facilitate the passage of the cable 4 so that the cable 4 can be connected to the circuit board 2.
[0039] like Figures 1 to 4 As shown, circuit board 2 is installed inside housing 1. Circuit board 2 houses a main control chip, a temperature and humidity module, a potentiometer adjustment knob 201, a power connector, and a relay. All components are electrically connected to the main control chip. The temperature and humidity module monitors the ambient temperature and humidity. The main control chip compensates for the humidity measurement based on the temperature data to eliminate the influence of temperature changes on the humidity measurement.
[0040] The circuit board 2 is connected to an ADC converter. The potentiometer adjustment knob 201 is connected to the main control chip through the ADC converter. When the knob cap 3 is rotated, it can drive the potentiometer adjustment knob 201 to rotate. The main control chip can read the rotation angle of the potentiometer adjustment knob 201 and convert the voltage value into a humidity value, i.e., the set humidity value, according to the rotation angle.
[0041] In addition, circuit board 2 is equipped with a GPIO interface. The relay is connected to the main control chip through the GPIO interface, which facilitates the main control chip's control of the relay. That is, when the ambient humidity is higher than the set humidity, the main control chip controls the coil inside the relay to activate and sends a dehumidification signal to the dehumidifier through the signal transmission line, and the dehumidifier starts to run and perform dehumidification.
[0042] This application uses an electronic humidity control device, which, compared with traditional mechanical humidity control devices, eliminates the need for cumbersome mechanical mechanisms, has a longer service life, fewer mechanical structures, is not affected by low-temperature environments, and has a wide operating temperature range; and uses electrical signal transmission, resulting in high humidity control accuracy.
[0043] Specifically, a number of second connecting screws 202 are connected to the circuit board 2, and the circuit board 2 is mounted on the lower shell 101 by the number of second connecting screws 202.
[0044] like Figures 1 to 4 As shown, the knob cap 3 is rotatably mounted on the upper shell 102. The knob cap 3 is connected to the potentiometer adjustment knob 201. The user can rotate the potentiometer adjustment knob 201 by rotating the knob cap 3. The angle of rotation of the potentiometer adjustment knob 201 converts the voltage value into a humidity value, i.e., the set humidity value, under the action of the ADC converter.
[0045] like Figures 1 to 4 As shown, one end of cable 4 passes through through hole 1041 and is connected to the power connector, while the other end of cable 4 is connected to the dehumidifier. Cable 4 is used to transmit power and humidity signals.
[0046] Cable 4 includes a power cable and a signal transmission cable. The signal transmission cable includes a shielding layer to reduce electromagnetic interference and ensure the stability of signal transmission. One end of the signal transmission cable is connected to a relay, and the operation of the coil inside the relay controls whether a humidity signal is output.
[0047] In addition, a mesh tail 401 is provided on the outside of the cable 4. The mesh tail 401 is connected between the cable 4 and the side sealing plate 104 to protect the cable 4 and extend the service life of the cable 4.
[0048] Specifically, the end of cable 4 furthest from the tail 401 is connected to a power connector 402, which is connected to the dehumidifier. The humidity signal is transmitted to the dehumidifier's main control board via the signal transmission line and the tail 401, and the main control board then controls the dehumidifier to start dehumidifying.
[0049] In practical use, the user can preset the dehumidification humidity value by rotating the knob cap 3, which in turn rotates the potentiometer adjustment knob 201. The main control chip on the circuit board 2 can read the rotation angle of the potentiometer adjustment knob 201 and convert the voltage value into a humidity value based on the rotation angle, which is the humidity value set by the user for dehumidification.
[0050] Meanwhile, the temperature and humidity module on circuit board 2 also monitors the ambient humidity. The ambient humidity value monitored by the temperature and humidity module is read by the main control chip, which compares the set humidity value with the ambient humidity value. When the ambient humidity value is higher than the set humidity value, the main control chip controls the coil in the relay to activate and sends a dehumidification signal to the dehumidifier through the signal transmission line, and the dehumidifier starts to run and perform dehumidification. When the ambient humidity value is lower than the set humidity value, the coil in the relay does not activate, and the dehumidifier does not work.
[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
