Compared with the prior art, the utility model discloses can block the key hole when the door is closed the state to prevent that external dust from getting into in the key hole, lead to the key hole to rust or sensitivity reduces.

According to the scheme II, the scheme is the optimization of the basic scheme, the face recognition equipment is arranged on the middle upper portion of the door body, and therefore the situation that children touch the face recognition equipment with curious hands is avoided, and the equipment is damaged.

And in the third scheme, the face recognition unit is preferably connected with the support column at an angle between 20 and 90 degrees, so that the face recognition unit can collect face images of shorter people only by raising heads.

Scheme four, this is the preferred of basic scheme, the bottom of baffle is equipped with the plastic strip, can effectually avoid damaging the baffle because of rubbing between baffle and the spout, and then influences the fender effect that separates of baffle.

And a fifth scheme is preferable as the basic scheme, and the buffer spring is arranged on the right side surface of the baffle plate, so that the collision sound of the baffle plate and the second electromagnet can be weakened.

And the power supply comprises a battery tank and two lithium batteries, the lithium batteries have high energy density, high voltage platforms of the lithium batteries and light weight, and the battery power supply pack is convenient to form.

And a seventh scheme is the optimization of the first or sixth scheme, and a lithium battery low-power reminding device is further arranged on the inner surface of the door body, wherein the low-power of the lithium battery is 2.1-2.6V, so that a user can be reminded of replacing the battery when the battery is low in power.
