Description

TECHNICAL FIELD

[0001] The utility model relates to soap dispenser related technical field, especially a kind of induction type automatic foam soap dispenser. BACKGROUND

[0002] Foam soap dispenser is a device that can be used for hand washing by pressing pump head. In order to improve the enthusiasm of children to wash their hands, a foam spraying molding member is usually connected to the outlet position of the soap dispenser. The foam is output from the foam spraying molding member and presents a specific shape foam pattern to attract children. The existing foam soap dispenser generally generates foam through an internal foaming pump. The foam generated by the foaming pump is transported to the foam spraying molding member through a foam connecting pipe and a foam output hole. The specific shape foam is output through the foam spraying molding member. Since the foam is transported through the foam connecting pipe for a certain distance, it is easy to cause partial foam water, and the stability is poor. When the generated foam pattern is placed on the hand and the palm is turned over, the foam is easy to fall off from the hand, which reduces the playability and the enthusiasm of children to wash their hands. Therefore, it is an urgent technical problem to design a foam soap dispenser that can uniformly and stably generate foam, has clear foam pattern outline, can maintain the three-dimensional feeling of foam pattern and is not easy to collapse quickly, and has good foam adhesion.
