Description

Full-invisible square bottle soap dispenser

Technical Field

The application relates to the technical field of daily necessities, in particular to a full-invisible square bottle soap dispenser.

Background

At present, in industries such as hotels or aviation, independent toilets and washrooms are generally arranged, and cleaning products such as shampoo or bath foam are usually placed in the washrooms for direct use when people wash.

However, when these cleaning products are placed, a placing frame is generally installed on the wall of a bathroom, and then the bottle containing the cleaning products is directly placed on the placing frame, so that people can directly squeeze the bottle for use when bathing. However, when some tenants leave the hotel, the cleaning products in the hotel can be directly taken away along the hotel, so that certain loss can be caused to the hotel. The bottle can be taken at will, and certain potential safety hazards can be caused.

The chinese patent document CN215533883U provides a soap dispenser device for locking a soap bottle, which comprises a soap bottle, a bracket and a locking assembly, wherein by setting the soap bottle and the bracket, after the soap bottle is placed in a limiting ring on a supporting plate, a fixing piece is rotated, a clamping part on the fixing piece is clamped into a clamping groove at the bottom of the soap bottle, and the free end of the fixing piece is fixed on the supporting plate through the locking assembly, so that the soap bottle can be stably fixed on a bottom plate, and by using the locking assembly, magnetic force attraction is applied to a magnetic rod through an external magnetic object to control the magnetic rod to move downwards and unlock, so that when the locking assembly is not opened, the soap bottle cannot be separated from the supporting plate, thereby avoiding people from directly taking the soap bottle away; however, the device has a complex structure, and has the problems of space occupation and poor appearance, which results in poor user experience.

In addition, there are some soap dispenser devices on the market, including an L-shaped metal lock and a soap bottle, where the vertical surface of the L-shaped metal lock is fixedly connected to a wall, and the lateral surface of the L-shaped metal lock is disposed between the pump head and the bottle body of the soap bottle, which has the disadvantages of large volume and occupying space, and the intention of "locking" the bottle is obvious, so that the user has negative psychological implications such as "protected", "taken as a thief", etc., and the sense of protection may be uncomfortable for the user, and further result in poor user experience.
