Technical Field

The invention relates to the field of liquid outlets, in particular to an induction type liquid outlet device.

Background

The liquid outlet device is a common liquid supply device in life, and liquid such as disinfectant, hand sanitizer or cleaning solution can be stored in the liquid outlet device and discharged when needed for users to use.

Common liquid outlet devices can be roughly divided into contact type liquid outlet devices and non-contact type liquid outlet devices, and when the contact type liquid outlet devices are used, a user needs to discharge liquid through pressing or other contact type operations; when the contact type liquid outlet device is used, a user does not need to contact with the liquid outlet device, and liquid in the liquid outlet device can be automatically discharged after the human body is sensed.

Compared with a contact type liquid outlet device, the non-contact type liquid outlet device can prevent a user from contacting with the liquid outlet device, so that bacteria or viruses can be prevented from being transmitted among the users through the liquid outlet device. Therefore, non-contact liquid discharge devices are widely used.

The traditional non-contact liquid outlet device has the working principle that the sensing assembly senses the appearance of a human body and then drives liquid to be discharged in a motor driving mode. It should be pointed out that, traditional non-contact goes out liquid device and at work, need pass through three processes of human appearance of response subassembly response, transmission of sensing signal and motor drive liquid discharge, the discharge of liquid has certain time delay, and the human liquid discharge that appears can take longer time.

On the other hand, the conventional non-contact liquid outlet device usually needs to be connected with an external power supply during working so that the motor works to drive liquid to be discharged. That is to say, in the places without external power supply, such as outdoor temporary activity places, temporarily-built cleaning and/or disinfection places, external power supply can not be provided for the traditional non-contact liquid outlet device, so that the traditional non-contact liquid outlet device can not be normally used.

In view of the above, there is a need for an improvement of the conventional non-contact liquid outlet device.
