Description

Technical Field

[0001] This utility model relates to the technical field of temperature monitoring devices, specifically to an online temperature monitoring device for shaped clay embryos with wireless charging function. Background Technology

[0002] Currently, in order to ensure the quality and effectiveness of fermentation, the internal temperature of the fermentation room needs to be monitored during the fermentation process. There are generally two types of traditional monitoring devices.

[0003] One type is an offline temperature detection device: This device is generally equipped with a dry cell battery or a button battery. During testing, the tester actively triggers the temperature collection and manually records the test data by reading the meter. However, the offline temperature detection device has a single function, requires manual triggering of data collection and recording, and cannot achieve timed collection and storage of large amounts of data.

[0004] Another type is an IoT wired charging online temperature detection device: the device can collect temperature data at regular intervals and transmit the data to the server via wireless communication. The device has a built-in high-capacity lithium battery and needs to be charged regularly through the wired charging port, requiring an external charging port.

[0005] The curing room is a high-temperature and high-humidity environment. It is difficult for any of the temperature detection devices mentioned above to prevent water vapor or liquid condensate from entering the equipment. If water vapor or liquid condensate enters the equipment, it can easily cause a short circuit and permanent damage to the product. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a wireless charging circuit board inside the casing, which works in conjunction with a wireless charging coil. When an external wireless charger approaches the waterproof end cover, it induces an electromagnetic current with the wireless charging coil inside the waterproof end cover. Under the influence of an alternating magnetic field, the wireless charging coil generates an induced current.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment discloses an online temperature monitoring device for mold blanks with wireless charging function, including a housing 1 and a lithium battery 2 assembled inside the housing 1. A waterproof end cap 3 is threadedly connected to one end of the housing 1, and a sealing ring 8 is fitted at the threaded interface between the waterproof end cap 3 and the housing 1. Figure 1 and Figure 2 As shown, in this application, the outer shell 1 and the waterproof end cap 3 are connected by threads. The outer shell 1 is made of stainless steel, which can improve the corrosion resistance of the outer shell 1. Two sealing rings 8 are fitted at the threaded interface between the outer shell 1 and the waterproof end cap 3 to seal and waterproof the connection between the outer shell 1 and the waterproof end cap 3. The lithium battery 2 is fixedly installed inside the outer shell 1 to power the entire device.

[0022] More specifically, the interior of the outer casing 1 houses a wireless charging circuit board 4. A charge / discharge management module 5 for charging and discharging the lithium battery 2 is soldered onto the surface of the wireless charging circuit board 4. One end of the wireless charging circuit board 4 has a wireless charging coil 6, and a magnetic shielding sheet 7 that engages with the wireless charging circuit board 4 is mounted on one side of the wireless charging coil 6. The coil connector of the wireless charging coil 6 is soldered to the wireless charging circuit board 4, as shown below. Figure 1 , Figure 2 and Figure 3 As shown in this application, the wireless charging coil 6 is designed at one end of the wireless charging circuit board 4 and is located inside the waterproof end cover 3. The wireless charging coil 6 is used to receive the magnetic energy emitted by the transmitter of the wireless charger. The wireless charging coil 6 generates electromagnetic induction and produces an induced current under the action of the alternating magnetic field. The magnetic shielding sheet 7 is designed at one end of the wireless charging circuit board 4 and is clipped onto the wireless charging circuit board 4. The wireless charging coil 6 is glued and fixed to the magnetic shielding sheet 7, which can increase the magnetic flux, concentrate the magnetic field, optimize the magnetic field distribution, and improve the charging efficiency. The wireless charging circuit board 4 is fixed inside the outer shell 1 with bolts to rectify and stabilize the coupled magnetic energy. At the same time, the wireless charging circuit board 4 also integrates a charge and discharge management module 5 for charging and discharging the lithium battery 2, which can control the charging and discharging of the lithium battery 2.

[0023] Furthermore, a sensor interface 9 is mounted on the top of the outer casing 1, and a sensor probe 10 is threaded onto the surface of the sensor interface 9. A sensor main control board 12 is soldered onto the wireless charging circuit board 4, and the sensor main control board 12 and the sensor interface 9 are connected by wires, such as... Figure 1 and Figure 2 As shown, the sensor interface 9 is designed at the bottom of the housing 1 for mounting and fixing the sensor probe 10. The temperature data detected by the sensor probe 10 can be transmitted to the sensor main control board 12 through the sensor interface 9, and then transmitted to the cloud server through the sensor main control board 12 to complete the detection of the temperature of the entire room.

[0024] Furthermore, a heat sink 11 is embedded in the surface of the waterproof end cap 3. The heat sink 11 works in conjunction with the wireless charging circuit board 4. The surface of the sensor main control board 12 integrates a standby module 13, a timed wake-up module 14, a temperature sampling module 15, and a wireless transmission module 16, respectively. Figure 1 and Figure 3 As shown, the heat sink 11 is designed on the surface of the waterproof end cover 3, and part of the heat sink 11 extends into the interior of the waterproof end cover 3. When the operating temperature of the wireless charging circuit board 4 rises, the temperature of the space formed between the waterproof end cover 3 and the outer shell 1 also rises. When the temperature of this separate space is higher than the outside temperature, the heat sink 11 can frequently exchange heat with the outside environment temperature, thereby reducing the temperature of the separate space. The standby module 13 is soldered to the surface of the sensor main control board 12. When the temperature monitoring device does not need to work, it can control the device to enter sleep mode, so that it is in an ultra-low power standby state under normal conditions, reducing power consumption. The timed wake-up module 14 is used to control the device to wake up automatically at regular intervals. It works in conjunction with the temperature sampling module 15. The timed wake-up module 14 wakes up the sensor main control board 12. The sensor main control board 12 performs data acquisition through the temperature sampling module 15. The wireless transmission module 16 is used to transmit the data collected by the sensor main control board 12 to an external terminal and upload the data.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
