Price: $9.17 ($5.99 on sale)
This dispenser is designed to automatically squeeze out a portion of soap on the hand. It’s suitable for both bathroom and kitchen.
If I still doubted to buy it or not to, the discount of almost 40% did the trick. I was also attracted by the lack of external "chrome" parts as in other models. It seems to me that its current appearance is more calm and appropriate than in chrome.
Unboxing
Everything is standard here. A plastic zip bag with some bubble wrap on the inside.
Inside, there was a box with a dispenser. The cardboard box is thick, but not enough. On the sides it was a bit flattened during transfer, although the appearance was’nt particularly affected.
Inside the box there was a dispenser additionally placed in the package of bubble wrap. There was also a user manual. That's the whole content.
The dispenser is’nt very large in size, at 400ml of liquid. Size is 20 x 12 x 8cm. Side walls made of transparent plastic, so you can see the level of liquid in the dispenser.
The dispenser is electronic, reacting to the touch of the hand or any object to it. Powered by 4 AAA batteries. The battery pack is located at the bottom of the dispenser and it’s easy to open. The lower position of the batteries is also convenient in that the empty dispenser will stand safely on the surface without tilting. Soft legs additionally help to stand safely on any surface without sliding.
The item has the bottom switch. There are 3 modes – “off”, “on”, “on + beep”. If it’s on the simple «mode on», the dispenser quietly give a portion of soap, but on the “on+beep” it beeps additionally, indicating that a portion of soap was given.
In this picture, there following components (from left to right) – a sound speaker, a screw, an IR signal receiver, a dispenser nozzle from where the liquid comes out.
Schematically, there is an IR led at the bottom of the front panel, and in the upper part of the dispenser there is an IR receiver. If an object interrupts the beam from the led to the receiver, the electronics are triggered, and the dispenser switch on a pump that squeezes out a portion of soap.
There is the neck on top of the dispenser which soap is poured into. On the lid there is a rubber stopper, which hermetically closes the container with liquid.
The inner capacity of the bulb, which will be filled with soap.
The user manual from the kit. It is printed only on the one side of the sheet.
Disassembly
Let’s examine the dispenser. We start with the dispensor on top.
I remove the lid. There is a visible liquid container under the lid, the speaker (with a green base) fixed with a drop of black glue. Further, a big black drop holds the IR receiver, and at the very end there is a dispenser tube, which the liquid leaves through.
Let's examine the base of the dispenser.
There is a battery pack for 4 AAA batteries and a board with a controller attached to it.
Through connectors the board is attached to the motor, which rotates the pump. The second loop wires goes to the top of the dispenser to the speaker and receiver. The wires are laid inside the body and cannot be seen from the outside. The IR transmitter is hidden under the black drop in the last picture.
Use
I decided to use the dispenser in the kitchen. So I poured there a jar of soup.
When putting a hand or a washcloth close to the dispenser, it starts working, and gives a portion of soap with a quiet buzzing.
Now about specific of the device.
It faces some difficulties when it has to deal with thick liquids. The image shows a portion of soap. I think you need to dilute soap with water or use more liquid one. But I don’t think this is the disadvantage of the device, it’s more “savings”.
By the way, I think that it will be comfortable for children. With it, handwashing will be much easier and cleaner, as the child will get the necessary amount of soap.
