Description

Thing networking temperature/humidity changer that can wirelessly charge

Technical Field

The utility model relates to a thing networking field, concretely relates to thing networking temperature/humidity changer that can wirelessly charge.

Background

The internet of things is a network which connects any object with the internet through various sensing technologies (RFID, sensors, GPS, cameras, laser scanners … …) and various communication means (wired, wireless, long-distance and short-distance … …) so as to realize remote monitoring, automatic alarming, control, diagnosis and maintenance and further realize the integration of management, control and operation.

The temperature/humidity transmitter is a common device in the internet of things, temperature/humidity data is a common and important physical parameter, and is necessary in the field of smart home, for example, temperature/humidity monitoring of a refrigerator and the like. When the power cord is used in a refrigerator, the power cord is led out of the refrigerator from the inside of the refrigerator, and holes are often required to be drilled and then sealed. Although the technical problem can be solved to a certain extent, the refrigerator is still used on the basis of the damage and repair of the original refrigerator structure. If the power cord is not used, and a battery is used, the endurance is also deficient.

Alternatively, the temperature/humidity sensor probe is typically placed inside the refrigerator, and the main unit is placed outside the refrigerator, but the refrigerator still needs to be removed from the hole.

SUMMERY OF THE UTILITY MODEL

In view of this, for solving the above-mentioned technical problem, the utility model aims at providing a thing networking temperature/humidity changer that can wirelessly charge can realize need not to destroy former refrigerator structure, the technological effect that again can be real-time wireless to charge.

The adopted technical scheme is as follows:

the wirelessly-chargeable Internet of things temperature/humidity transmitter comprises a shell and a power adapter, wherein a first circuit board is arranged in the shell and is electrically connected with a first coil module; the power adapter is provided with a second circuit board, a second coil module electrically connected with the second circuit board and a power connector electrically connected with the second circuit board, and the first coil module and the second coil module form an electromagnetic induction type wireless charging module; when the refrigerator is used, the shell is arranged in the refrigerator; the power adapter is externally arranged outside the refrigerator.

Further, a storage battery is electrically connected to the first circuit board.

Further, the temperature/humidity sensor is a single-temperature, double-temperature or triple-temperature sensor.

The beneficial effects of the utility model reside in that:

through making first coil module and second coil module form the wireless module of charging of electromagnetic induction formula to can produce the wireless function of charging, just so avoid destroying the derivation power cord or the probe of repairing the refrigerator formula. But can directly arrange the power adapter outside the refrigerator, can charge the thing networking temperature/humidity transducer in the refrigerator in real time.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 and 2, the wirelessly chargeable internet of things temperature/humidity transmitter comprises a housing 10, wherein a temperature/humidity sensor 20, an a/D conversion module 30, an MCU 40 and a wireless communication module 50 are arranged in the housing 10; the temperature/humidity sensor 20 is electrically connected to the a/D conversion module 30, and is configured to convert the acquired temperature/humidity analog signal into a digital signal through the a/D conversion module 30, the a/D conversion module 30 is electrically connected to the MCU 40, and is configured to transmit the digital signal to the MCU for processing, and the MCU 40 is electrically connected to the wireless communication module 50, and is configured to wirelessly transmit the processed digital signal through the wireless communication module 50. The MCU can adopt the existing singlechip of the ultra-low power consumption product. The A/D conversion module can adopt the existing digital-to-analog converter.

The a/D conversion module 30, the MCU 40, and the wireless communication module 50 are integrated on the first circuit board 1. The first circuit board 11 is electrically connected with a first coil module 12.

The internet of things temperature/humidity transmitter capable of being wirelessly charged is also provided with a power adapter 2, the power adapter 2 is provided with a second circuit board 21, a second coil module 22 electrically connected with the second circuit board 21 and a power connector 23 electrically connected with the second circuit board 21, and the first coil module 11 and the second coil module 23 form an electromagnetic induction type wireless charging module; when used in a refrigerator, the housing 10 is built in the refrigerator 60; the power adapter 2 is externally disposed outside the refrigerator 60.

The principle of electromagnetic induction wireless charging is that a primary coil (a second coil module) obtains alternating current with a certain frequency (a power supply connector is connected with an alternating current power supply), and certain current is generated in a secondary coil (a first coil module) through electromagnetic induction, so that energy (current) is transferred to a receiving end (an internet of things temperature/humidity transmitter) from a transmission end (a power supply adapter).

Therefore, when the temperature/humidity sensor is used, the shell 10 is arranged in the refrigerator 60, the power adapter 2 is arranged outside the refrigerator 60, and the temperature/humidity sensor of the internet of things can be charged in real time in a wireless charging mode. Meanwhile, the structure of the original refrigerator is not required to be damaged.

The utility model discloses a temperature/humidity transducer can be single temperature, two temperature or three temperature sensor, also can be humidity transducer or temperature and humidity sensor to form different embodiments.

The utility model discloses a temperature/humidity sensor includes but is not limited to and is equipped with temperature/humidity sensor 20, AD conversion module 30 and MCU 40. This is the most basic arrangement in the temperature/humidity sensor, and more functional modules can be added on the basis of this, which should be included in the protection scope of the present invention.

It is worth mentioning that A/B includes three meanings: a exists alone, A and B exist simultaneously, and B exists alone. That is the thing networking temperature/humidity transducer contain three kinds of transmitters: the system comprises an Internet of things temperature transmitter, an Internet of things humidity transmitter and an Internet of things temperature and humidity transmitter. I.e. "/" means "and/or".
