The Benefits of Using smart sensor soap dispenser

Device that dispenses a controlled amount of hand washing liquid

Link to JAKA

An automatic soap dispenser is a device that dispenses a controlled amount of soap solution (or a similar liquid such as a hand sanitizer). They are often used in conjunction with automatic faucets in public restrooms. They function to conserve the amount of soap used and stem infectious disease transmission.

History

[

edit

]

The idea for the first automated dispenser was submitted by Guey-Chuan Shiau to be patented in . The patent was under the name, "Automatic Cleaning-liquid Dispensing Device". The patent was issued in . The patented device was under the following description: "An automatic cleaning-fluid dispensing device includes: a containing structure for containing cleaning fluid; a sensing device disposed on a base member being installed in the lower portion of said containing structure wherein said base member is provided with an outlet, a sensing circuit disposed on a circuit board, a motor arrangement electrically connected to the sensing circuit, an outlet for passing a light source of the sensing circuit therefrom so as to detect the presence of an external object closing on the light source; and a dispensing mechanism, which is composed of a push structure functionally connected with the driving motor and a pumping structure operatively engaged with the push structure, installed on the base member in connection with the sensing device; whereby when an external object closes to the sensing device, a given amount of the contained cleaning fluid in the containing structure will be automatically supplied for cleaning purposes.".[1]

Application

The implementation of automatic washroom supplies has increased dramatically. An increasing number of public locations and private institutions have been incorporating touchless technology into their washrooms.

Public locations

Automatic technology has permeated public washrooms. Journalist Michael Sasso once termed it as, "Hygienic Company Brings Space Age to Bathroom." He wrote in reference of the Tampa International Airport. The first automatic urinal was implemented in and in 16 years, "the airport had 143 automatic urinals, 390 automatic-flush commodes and 276 automatic faucets".[2] Touchless technology has become a regular component of modern washroom facilities.

Hospital setting

A study was conducted in the accession area of the clinical microbiology laboratory and the outpatient dentistry department of the University of Virginia Medical Center. Studies were done to evaluate the particular antiseptic solution and the automatic dispensers in a hospital setting. The study was conducted for two months, at the conclusion, the effectiveness of the solution and dispenser was surveyed. Although the particular alcohol antiseptic was disliked because of the skin-drying effect of the alcohol solution, the dispenser itself was recommended for greater use throughout the healthcare facilities.[3]

The filth, poverty, disease that permeated nineteenth century&#;s society was drastically reduced by revolutionary sanitation movements throughout the twentieth century. Although several other advances... can be etiologically and temporally related to some of these diseases, the causal evidence (e.g., temporal sequence, consistency, biologic plausibility) is consistent with the hypothesis that personal hygiene is one other factor that helped to determine the decline.[4] The advances of hygiene, such as that of the automatic soap dispenser, can be considered as one of the more silent victories of public health and continues to be an important disease prevention strategy, even in this "modern" era when the "gospel of germs" has waned in popularity.[5]

A strong corollary in the decline of the mortality rate is that of hand-washing (National Center for Health Statistics).

Mechanisms

[

When washing hands, the user&#;s hands are placed under the nozzle and before the sensor. The activated sensor will further activate a pump that dispenses a premeasured amount of soap from the nozzle.[6]

Radar-based sensor

[

This kind of sensor sends out bursts of microwave or ultrasound energy and waits for the energy to reflect back. In a stagnant situation, the energy will bounce back in a normal pattern. When hands are placed in the basin, the energy emitted from the sensor will bounce back irregularly which triggers the dispensation of soap.[7] Modern sensors used in electronic faucets, electronic flush valves and electronic soap dispensers use Infrared light with wavelength in the range of 850 nm. The sensor employs an emitter and a collector. The emitter emits pulses of infrared light while the collector, which is positioned to face in the same direction as the emitter, "sits" dormant waiting to sense the emitted pulses. When no hands are present in front of the device, no reflection of light takes place, and therefore, no pulse is sensed. When hands are present in the path of the emitted light, a portions of the emitted infrared light is bounced back in the direction of the collector which then becomes excited by the light (in the event a photodiode is used) and generates voltage to switch the pump on. If a photo transistor is utilized, then the photo transistor, upon sensing the infrared pulse, will simply switch the pump on.[8]

Photo sensor

This mechanism is composed of two parts, a source of focused light (usually a laser beam) and a light sensor. When the user&#;s hands are placed in line of the beam of light, the pump mechanism is activated by the disruption that is sensed by the light sensor.[7]

Passive infrared sensor

[

Infrared sensors detect infrared energy that is emitted by one&#;s body heat. When hands are placed in the proximity of the sensor, the infrared energy quickly fluctuates. This fluctuation triggers the pump to activate and dispense the designated amount of soap.[7]

Touchless

The advancement of the automatic soap dispenser further creates an even more sterile environment. When various individuals use the pump, they will leave behind a variety of bacterial colonies. These colonies will interbreed and lead to a more resistant strain of bacteria that can re-contaminate different hands and would not be completely eliminated by the anti-bacterial soap. Wider spectra or higher levels of resistance, in the colonies that are present, are due to interaction and/or complementation between the resistance genes.[9] Without having a wide variety of individuals touching the pump, bacterial transmission will be eliminated.

Preset increments

[

edit

]

Dispensers will only distribute a set amount of soap per motion activation. A predetermined amount to be dispensed can be set to a highly efficient quantity in which waste will be minimal.

Versatility

[

The mechanisms of the dispenser that work for soap may also work for other liquids: soap, hand sanitizer, lotion, laundry detergent etc. The wide range of possibilities extends the use of the dispenser to various other locations other than the bathroom.
