Healthy life, healthy drinking water in the present. The domestic thermos cup brand "Hals" and Huawei jointly launched a smart water cup to support the connection with Huawei's HiLink smart life APP. However, as a water cup, waterproof is crucial, so how is the waterproof and intelligent part of this cup perfected?
Disassembly steps
The smart part of the Hals smart cup is in the lid of the cup, so it is mainly for the lid part of the cup to be disassembled. The overall appearance of the cup lid is made of plastic material, and there is a metal rod and a coil spring between the upper lid and the lid body, which uses the telescopic force of the spring to automatically bounce the lid when the lock is opened.
The inside of the lid is equipped with a food-grade silicone inner plug, and a magnet is used to detect the opening and closing of the lid.
The drinking fountain is made of food-grade plastic, which can be installed and removed by rotating 90 degrees. The bottom is fitted with a food grade silicone ring and a tea separator. The tea separator is made of food-grade plastic, and silicone rings are used to prevent water and water vapor from penetrating into the internal electronics of the lid.
The cup lid lock is fixed with a small iron rod, there is a spring after the button, the monochrome display is fixed with a snap between the monochrome display and the main shell of the cup lid, and there is translucent waterproof glue on the back of the display. The lid has a plastic seal inside. There are 4 screws under the sealing ring. A waterproof adhesive is applied between the screw and the sealing ring to prevent water vapor from penetrating.
After the screw is removed, gently pry the inside of the main shell, separate the main shell and the inner support shell, and you can see the cup motherboard. The motherboard is crescent-shaped around the water cup outlet, the motherboard uses a plug-in interface to connect the vibrator, battery and temperature sensor respectively, and the water detection coil wire is welded to the side of the motherboard through spot welding. A green PCB Bluetooth module board is also soldered on the front
Inside the main case is a black silicone pad for waterproofing, and the display board is connected to the motherboard through the gap between the housing and the silicone pad. The seam between the soft board and the silicone pad is coated with waterproof adhesive seals.
The motherboard is a double-layer, single-sided motherboard. The 200mAh lithium-ion battery is installed at 90 degrees inside the support case with a layer of foam glue on the surface. Screw the vibrator bracket under the battery. The flat vibrator is fixed to the plastic holder with viscose.
There is a circle of silicone on the periphery of the drinking water mouth, and a layer of copper foil on the inside, which uses the fine current generated by the fine friction between the water flow and the drinking water mouth, and at the same time uses software algorithms to detect the amount of drinking water and the amount of residual water. The back of the temperature sensor is sealed with a waterproof adhesive seal.
The bottom of the cup is covered with a silicone anti-slip pad with double-sided adhesive, and the surface of the non-slip mat has the Hals brand logo.
Motherboard IC information
The main IC on the front of the motherboard (below):
1, Telink- TLSR8232F512ET32 - low power 32-bit Bluetooth 5.0 SOC chip.
2. Lamp control touch chip
3. Micr One-lithium battery charging chip
4. DC-DC boost chip
5. DC-DC boost chip
The Bluetooth module model is: Pippijia BM1032, produced by GCA Digital Drinking Appliance Technology. The interior adopts Tailing Microelectronics Telink TLSR8232F512ET32 32-bit Bluetooth 5.0 SOC.
Summarize the information
Huawei Smart Select Hals Smart Water Cup, the main smart part around the lid part. Therefore, it is mainly to disassemble the cup lid, the overall disassembly is relatively simple, but due to the waterproofness and the need for contact with the human body, the lid uses food-grade silicone materials and waterproof adhesives for sealing and waterproofing. Although it can be restored after disassembly, the tightness cannot be guaranteed.
In the smart part, the chip solution on the Hals smart water cup is a national production solution, mainly the Tailing Microelectronics Telink Bluetooth SoC solution. Tailing Microelectronics' Bluetooth Low Energy SoC also appeared in the Small Body Fat Scale 2 not long ago. (Editor: Judy)
