[0013] Compared with the prior art, the present utility model has the following beneficial effects:
[0014] 1. For this instant liquid heater, by pulling upward the extension block on the outer wall of the locking piece, the locking piece moves upward on the inner wall of the mounting shell. At this time, the upward movement of the mounting shell drives the first spring to contract, so that the locking piece is separated from the rectangular groove on the top of the mounting piece.

[0015] 2. For this instant liquid heater, water flows into the inside of the mounting shell from the water inlet, and then enters between the upper shell and the lower shell of the heating chamber through the opening on the top of the upper shell of the heating chamber. At this time, the water impacts the sliding piece, so that the sliding piece moves. At this time, due to the movement of the sliding piece, the second spring contracts, and the second spring increases the pressure on the pressing block, so that the pressing block triggers the pressure sensor, and the pressure sensor sends an electrical signal to the circuit interruption device, so that the circuit interruption device is powered on. Then, the circuit interruption device transmits power to the heating sheet through the power-on head and the second connecting wire. When the pressure sensor is not triggered, the pressure sensor does not send a signal to the circuit interruption device, so that the circuit interruption device is in an open circuit state to prevent dry burning.
[0016] 3. When the liquid enters between the upper shell of the heating chamber, the liquid inlet speed is buffered through the water passing trough provided between the upper shell of the heating chamber and the lower shell of the heating chamber, so that the initial speed of the liquid when entering between the upper shell of the heating chamber and the lower shell of the heating chamber is reduced. By the liquid flowing inside the water passing trough between the upper shell of the heating chamber and the lower shell of the heating chamber, the flow rate of the liquid between the upper shell of the heating chamber and the lower shell of the heating chamber is reduced, so that the residence time of the liquid outside the heating sheet becomes longer, and the heating effect of the liquid becomes better.

[0030] In a preferred embodiment, a rectangular groove is provided at the top of the mounting piece 10, and the size of the rectangular groove is adapted to the size of the bottom of the locking piece 16.

[0033] In a preferred embodiment, an extension block is provided at the bottom of the sliding piece 19, and the extension block is penetrated by the guide rail 18.

[0034] Working principle: When using this device, water flows into the interior of the installation shell 1 through the water inlet 5. At this time, the water flows into the space between the upper heating chamber shell 8 and the lower heating chamber shell 9 through the notch at the top of the lower heating chamber shell 9. Then the water impacts the sliding piece 19, causing the sliding piece 19 to move. At this time, due to the movement of the sliding piece 19, the second spring 20 contracts, increasing the pressure of the pressing block 21 by the second spring 20, thereby triggering the pressure sensor 17 by the pressing block 21. The pressure sensor 17 sends an electrical signal to the circuit interruption device 3, causing the circuit interruption device 3 to be powered on. Then the circuit interruption device 3 transmits electricity to the heating sheet 11 through the power connection head 13 and the second connecting wire 12. After receiving the electricity, the heating sheet 11 starts to heat up, heating the water between the upper heating chamber shell 8 and the lower heating chamber shell 9. The water enters the inner wall of the water outlet 4 through the notch at the top of the upper heating chamber shell 8. The temperature sensor 6 inside the water outlet 4 detects the liquid temperature and transmits it to an external device through the first connecting wire 7 and the signal transmission head 14. When the heating sheet 11 needs to be replaced, pull up the extension block on the outer wall of the lock piece 16, causing the lock piece 16 to move upward on the inner wall of the installation shell 1. At this time, the contraction of the first spring 15 is driven by the upward movement of the installation shell 1, causing the lock piece 16 to disengage from the rectangular groove at the top of the installation piece 10. Then remove the two power connection heads 13 from the top of the circuit interruption device 3, hold the heating sheet 11 and pull it outwards, causing the heating sheet 11 to drive the installation piece 10 to be pulled out from the inner wall of the installation shell 1, and then it can be replaced.
