Detailed Description
In the technical scheme provided by the invention, when liquid enters a space formed by the upper shell and the lower shell from the liquid inlet and gradually flows to the liquid outlet through the tortuous liquid passage, the upper heater and the lower heater heat the liquid, so that when the liquid reaches the liquid outlet, the temperature of the liquid reaches a preset proper value, and therefore, when people, especially infants, bathe or wash hair, the liquid smeared on the body has a certain temperature, so that the liquid cannot feel cold and cannot catch cold.
Secondly, when the liquid is not heated, the deformable valve plate keeps the original shape and position, so that the gap is in a closed state, and the liquid cannot flow out through the liquid outlet; when the liquid is heated, the temperature of the liquid rises to start volume expansion, and the deformable valve plate is pressed downwards by the liquid so as to adapt to the expansion of the liquid, and the gap is still not opened; when the liquid is heated to a proper temperature, the volume of the liquid is further expanded, at the moment, the deformable valve plate is further pressed downwards under the pressure of the liquid, and the deformation action is carried out, so that the gap is opened, and then the liquid flows out through the gap, so that the purpose of self-adaptive liquid control is realized. That is, when the heated liquid is required to flow out, the liquid can smoothly flow out through the slit, and when the liquid is not heated or slightly heated but does not reach the required temperature, the slit is not opened, thereby avoiding improper liquid flow out.

a motor 300 disposed on the pipe 400; a kind of electronic device with high-pressure air-conditioning system
And a control circuit 500 electrically connected to the motor 300 and the bottle cap heating device 100.
The control circuit 500 drives the motor 300 such that the motor 300 pumps the liquid in the liquid container 200 into the bottle cap heating apparatus 100 via the pipe 400. Specifically, the liquid enters the space defined by the upper and lower cases 10 and 30 through the liquid inlet 36 shown in fig. 1 to 7, and when the liquid entering the bottle cap heating device 100 needs to be heated, the control circuit 500 controls the upper and lower heaters 20 and 40 to be electrically heated, and when the liquid gradually flows to the liquid outlet from the meandering liquid path, the upper and lower heaters 20 and 40 disposed under the upper and lower cases 10 and 30 heat the liquid in the flowing process, so that the temperature of the liquid reaches a predetermined proper value when the liquid reaches the liquid outlet 38, and thus the liquid smeared on the body, especially infants, has a certain temperature, so that the infants do not feel cold and the infants do not catch cold to cause health problems.
Further, with particular reference to fig. 8, when the liquid in the space is not heated, the deformable valve plate 52 maintains its original shape and position, so that the slit 56 is in a closed state and the liquid cannot flow out through the liquid outlet.
Referring next to fig. 9, as the liquid begins to heat, the liquid increases in temperature and begins to expand in volume, whereupon the deformable valve plate 52 is pressed downwardly by the liquid to accommodate the expansion of the liquid, while the slit 56 remains unopened.
Finally, referring to fig. 10, when the liquid is heated to a suitable temperature, the volume of the liquid is further expanded, at this time, the deformable valve plate 52 is further pressed downward under the pressure of the liquid, and the deformation is accompanied, so that the slit 56 is opened, and then the liquid flows out through the slit 56, thereby achieving the purpose of adaptive liquid control.

Preferably, at least the deformable valve plate 52 of the automatic fluid control valve 50 is made of an elastic silicone material, so that the deformable valve plate 52 can be more protruded and deformed downward under the external pressure, thereby opening the slit 56 and facilitating the fluid flowing out of the slit 56.
Preferably, the slit 56 formed on the deformable valve plate 52 of the automatic liquid control valve 50 is a straight slit 56 or a cross slit 56. Both slits 56 facilitate rapid opening under external pressure, thereby facilitating fluid flow from the slits 56.

Preferably, a temperature sensor 39 for detecting the temperature of the liquid in the vicinity of the liquid outlet 38 is provided on the bottom wall 31 at a position close to the liquid outlet 38. Still further preferably, the bottom wall 31 is provided with a positioning hole 37 at a position close to the liquid outlet 38, a sealing sleeve 392 is disposed in the positioning hole 37, a positioning sleeve 394 is disposed in the sealing sleeve 392, and the temperature sensor 39 is installed in the positioning sleeve 394. The sealing sleeve 392 serves as a seal to prevent the liquid in the space formed by the fastened upper and lower housings 10 and 30 from flowing out of the positioning hole 37 or to prevent external moisture from entering the space from the positioning hole 37. The positioning sleeve 394 is used to fix the temperature sensor 39.
Preferably, the upper heater 20 includes an upper heating wire 22 aligned with the liquid passage 35 on the bottom wall 31 of the lower housing 30, and an upper positive electrode 24 and an upper negative electrode 26 connected to both ends of the upper heating wire 22.
