TH4680U - Touchless hand sanitizer dispenser with replaceable bottles. - Google Patents

Abstract

This invented hand sanitizer device utilizes a pump mechanism to dispense sanitizer instead of the hand or body part. A pulling force from a central locking lever, attached to the pump head, activates the dispenser. This pumping mechanism employs an infrared light-blocking system with a light receiver/transmitter on the front of the sanitizer bottle. When the hand to be cleaned is placed in the infrared light path, the device dispenses sanitizer without the need to manually press the pump, thus avoiding contamination and microbial accumulation on the pump head.

Claims (4)

1. The contactless hand sanitizer dispenser with replaceable bottles consists of a housing with a width, height, and thickness to accommodate the sanitizer bottle. The top of the housing is fitted with a plate for mounting the electrical circuit (3), and at the back of the housing is a transformer (1) to convert the building's electrical current to a suitable level for the device, and a battery (2) is installed nearby to store the current for use in the device. The aforementioned electrical circuit (3) controls the operation of the motor (4) and receives signals from sensors (8) or (9). Specifically, on the top of the plate is a motor (4) which is attached to the plate. At the end of the motor (4) is a cam (5) that presses the end onto a metal rod (6) that passes through a hole in the plate and is positioned below the cam. The lower end of the metal rod (6) is placed on the dispensing head of the sanitizer bottle, and between the plate and the cam (5) is a spring (7) fitted onto the metal rod (6), which spring (7) is the It helps the iron rod (6) move up as the height of the cam has passed, and on the front, slightly to the right above the liquid bottle of the container, a sensor (8) is installed to send a signal when there is a blockage from the user's hand under sensor (8), to order the supply of electricity to the motor (4), causing the cam (5) to rotate and press the pump head of the hand sanitizer bottle and dispense the liquid. On the side of the cam (5), a sensor (9) is installed at a distance from the iron rod (6) at a height corresponding to the height of the top edge of the thickest part of the cam (5), to block the light at sensor (9) until the sensor (8) starts working. When the cam (5) rotates half a turn, causing the thinnest part of the cam (5) to rotate up to replace the thickest edge, the blockage at sensor (9) is removed. When sensor (9) is working, sensor (8) stops working, stopping the supply of electricity from the electrical circuit (3) to the motor (4), causing the motor to stop rotating, thus stopping the dispensing of the liquid. And the cam (5) rotates back to the ready position by the compression force of the spring (7) which pulls the iron rod (6) up to rotate the cam (5), causing the thickest part to return to block the light on the sensor (9) as before, and thus stopping the operation of the sensor (9). 2. A contactless hand sanitizer dispenser with replaceable bottles as per claim 1, in which the housing is made of white plastic and measures 12.2 centimeters wide, 14 centimeters long, and 17.9 centimeters high. 3. A contactless hand sanitizer dispenser of the type of replaceable sanitizer bottle according to Patent 1, in which a cam (5) is spherical in shape when viewed from the front and is made of white plastic or polyurethane. 4. A contactless hand sanitizer dispenser of the type of replaceable hand sanitizer bottle according to patent 1, in which the iron rod (6) is made of iron, has a length of 3.1 centimeters, and is placed vertically on the pump head of the hand sanitizer bottle.
