[0003] The existing pure drinking machine does not set a related low water level detection device in the raw water tank, so the user needs to manually observe the remaining water, which leads to poor operation experience. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a water level detection device and cooked water pure drinking machine, which can remind the user that the raw water tank is in a low water level state.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a water level detection device, comprising:

[0006] A raw water tank is provided with a raw water cavity, and a water outlet hole is arranged at the bottom of the raw water cavity;

[0008] A self-priming pump is provided with a self-priming inlet and a self-priming outlet, and the self-priming inlet is communicated with the water outlet hole;

[0009] A current detection module is electrically connected with the self-priming pump, and the current detection module detects the current of the self-priming pump;

[0010] A reminding module is electrically connected with the current detection module;

[0011] When the water level of the raw water tank is lower than the flow guide inlet, the self-priming pump is in a low load state, at this time, the current detection module detects that the current of the self-priming pump is a low load current, and the current detection module controls the reminding module to issue a low water level alarm reminder.

[0012] Further, the reminding module is a control indicator light, and when the current of the self-priming pump is a low load current, the control indicator light is a red light.

[0013] Furthermore, when the water level in the raw water tank is higher than the flow inlet, the self-priming pump is in a high-load state. At this time, the current detection module detects that the current of the self-priming pump is a high-load current, and the reminder module issues a normal water level reminder.

[0014] Furthermore, the reminder module is a control indicator light, and when the self-priming pump current is a high load current, the control indicator light is green.

[0015] Furthermore, it also includes a filter element, which has a filter element inlet and a filter element outlet, and the self-priming outlet is connected to the filter element inlet.

[0020] Furthermore, the kettle is equipped with a high water level probe and a low water level probe. When the high water level probe is triggered, the self-priming pump stops pumping water, and when the low water level probe is triggered, the self-priming pump starts pumping water.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) Due to the setting of the guide sleeve, when the position in the original water chamber is lower than the guide inlet of the guide sleeve, the self-priming pump is in a low load state (that is, there is no water for the self-priming pump to pump). At this time, the current detection module detects that the self-priming pump current is a low load current, and the reminder module issues a low water level alarm. The user can observe the reminder and know that the water level in the original water chamber is low, which makes it easier for the user to perform subsequent operations without the user having to actively check the water level.

[0023] (2) Users can determine whether water needs to be poured by controlling the color of the indicator light, which is very convenient to observe;

[0024] (3) the wastewater enters into the raw water cavity through the flushing valve and the water inlet, impurities of the wastewater are more and therefore inconvenient for the user to drink, usually need to be poured away, when the water level of the raw water tank is lower than the height of the flow guide sleeve, the low water level alarm reminding module can send a low water level alarm reminding, reminding the user to pour away the remaining water;

[0025] (4) the kettle is provided with a high water level probe and a low water level probe, when the high water level probe is triggered, the self-priming pump is closed to stop pumping, when the low water level probe is triggered, the self-priming pump starts to pump, so that automatic water filling into the kettle can be realized, and the kettle can be automatically heated when full of water.
