Description of the Related Art

There are many situations where it is desired to dispense liquid chemicals or other liquids into a receptacle having water or other liquid therein. There are also other situations where it is desirable to mix the liquid chemicals with water prior to the mixture being discharged into a receptacle. There are also situations wherein both of the above methods are required to be performed at one station where there is a need for injecting liquid chemicals into a first receptacle having water or other liquid therein and there is a need for mixing liquid chemicals with water prior to being discharged into another receptacle.

In each of those situations, the liquid chemicals are in a container such as a bottle with the chemicals being drawn therefrom by a pump or other means. Usually, the liquid chemical containers are not closely monitored as to the amount of liquid chemical remaining in the liquid chemical container. If the liquid chemical container becomes ernpty, the proper amount of chemical will not be supplied to the receptacle. Further, if the pumps run empty, they may become damaged.

There is therefore a need to provide an electronic detection system which includes an alarm which may audibly, visually or data indicate that the liquid chemical container is empty or some other disruption in the flow has occurred. There is also a need for remotely controlling the systems by way of a computer, a lap top, a tablet or a cell phone.

The co-pending application Ser. No. 15/443,106 filed Feb. 27, 2017 entitled AN AUTOMATIC DETECTION SYSTEM FOR DETECTING DISRUPTIONS IN THE FLOW TO A DISPENSING APPARATUS represents an improvement in the art. The instant invention represents a further improvement in the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

The first embodiment of the automatic detection system for detecting disruptions in the flow to a dispensing apparatus is referred to by the reference numeral 10 and is depicted in schematic form in FIG. 1. The numeral 12 refers to a liquid container, such as a bottle, which will usually contain chemicals but could contain other liquids. An insert 14 is inserted into the neck of the container 12 and may be of the type such as shown in my earlier insert patents, namely U.S. Pat. Nos. 9,242,847; 9,126,725; and 8,708,203 the disclosures of which are incorporated herein to complete this disclosure if necessary.

A flexible tube 16 extends from insert 14 of container 12 for supplying liquid to a valve module 18 which is available in the marketplace. Valve module 18 will usually be mounted on a vertically disposed support such as a wall, bracket, etc. Valve module 18 includes a first liquid intake port 20, a second liquid intake port 22, which is not utilized in the FIG. 1 embodiment and a liquid outlet port 24. A short tube 26 has its outlet end in fluid communication with the liquid outlet port 24. It should be noted that the container 12 may be positioned above valve module 18.

Valve module 18 includes an electrically operated valve 28 of conventional design and an electrically operated valve 30 of conventional design, which is not utilized in the FIG. 1 embodiment. The intake end of tube 26 is in fluid communication with the tube 31 which extends between the discharge side of valve 28 and the discharge side of valve 30. As seen, tube 16 is fluidly connected to the first liquid intake port 20 of valve module 18. When valve 28 is in its open position, liquid may pass therethrough so that the liquid is supplied to tube 31, the tube 26 and the outlet port 24. When valve 28 is closed, liquid may not pass therethrough.

A flexible tube 32 has its discharge end thereof fluidly connected to the liquid intake port 33 of pump 34. In this embodiment, the pump 34 is a peristaltic hose pump. However, other pumps such as a radial piston pump, a gear pump, a vane pump, a lobe pump, a piston pump, a Venturi pump, etc., could be used. A flexible tube 35 has its liquid intake end fluidly connected to port 24. The discharge side 36 of pump 34 has a hose, tube or pipe 38 extending therefrom to a receptacle 40 such as a sink, a tub, etc.

The valves 28 and 30 of module 18 are electrically connected to a conventional power source 42 by leads 44 and 45 respectively. The liquid intake end of tube 32 is fluidly connected to an optical sensor 46 positioned within an alarm module 48. The discharge end of tube 35 is fluidly connected to the liquid intake side of sensor 46. Optical sensor 46 will be described in greater detail hereinafter. Although it is preferred that the optical sensor 46 be positioned within alarm module 48, it could be located outside of alarm module 48. Alarm module 48 and optical sensor 46 are electrically connected to the power source 42 by a lead or leads 50. Alarm module 48 includes a visual signal device such as a light 52. Alarm module 48 also includes an audible signaling or warning device 54. Alarm module 48 will usually include a data alarm. Optical sensor 46 and alarm module 48 are configured to activate the devices 52, 54 and the data alarm upon the optical sensor 46 detecting a disruption of liquid flow through sensor 46 as will be described hereinafter. The alarm module 48 also includes a lighted reset button 56.

The numeral 58 refers to a computer driven controller which is electrically connected to the power source 42 by a lead or leads 60. Controller 58 is electrically connected to pump 34 by a lead or leads 62. Controller 58 is electrically connected to valve module 18 by a lead or leads 63. Controller 58 is electrically connected to the alarm module 48 and optical sensor 46 by a lead or leads 64.

The second system of FIG. 2 is identical to the system of FIG. 1 except that a second liquid container 12′ is utilized. Container 12′ is identical to liquid container 12. Container 12′ is fluidly connected to the liquid intake port 22 which is fluidly connected to the intake side of valve 30 by tube or pipe 65. It should be noted that the liquid containers 12 and 12′ may be positioned above the valve module 18.

Optical sensor 46 will now be described in greater detail. Optical sensor 46 includes a housing or box 66 having an interior 68. Housing 66 includes side walls 70, 72, 74 and 76. A cover 78 selectively closes the front of the housing 66. A liquid inlet fitting 80 is positioned in wall 76 with the fitting 80 being fluidly connected to the discharge end of tube 35. A liquid outlet fitting 82 is positioned in wall 74 with the fitting 82 being fluidly connected to the intake end of tube 32.

The sensor 46 includes an elongated optical tube 84 which has its ends fluidly connected to fittings 80 and 82. Tube 84 is clear or transparent. Sensor 46 includes a circuit board 86 in the interior thereof which is operatively electrically connected to the power source 42 by way of the lead 50. Circuit board 86 includes a transmitter or emitter 88 which extends from circuit board 86. Circuit board 86 also includes a receiver 90 which extends from circuit board 86 and which is spaced from transmitter 88. As seen, the optical tube 84 is positioned between the transmitter 88 and the receiver 90.

The exterior side of cover 78 has a power light 92, an empty light 94, a calibration successful light 96 and a calibration button or knob 98, all of which are electrically connected to the circuit board 86.

The sensor 46 will now be described in more detail. The sensor 46 is manufactured by TT Electronics. The part numbers of the TT Electronics sensor are OP550B and OP240B. Initially, the sensor 46 must be calibrated. The valve 28 is opened by the controller 58. The pump 34 is then actuated so that the liquid from container 12 is drawn through the open valve 28 and through tube 35 into the intake side of sensor 46 and through the optical tube 84. When the optical tube 84 is full, the calibration button 98 is depressed. This causes the system to calibrate the chemical that is being dispensed. After the calibration, the calibration successful light 96 will be lighted. The alarm system will be activated if there is a change in the liquid flow in the optical tube 84. If the optical sensor 46 detects a change in the liquid flow be it bubbles, lack of chemical or different chemicals, the alarm system will be activated. The alarm will continue until the problem is resolved.

The operation of the automatic detection system of FIG. 1 will now be described. A container 12 having the desired liquid therein is placed into position. The controller 58, at predetermined times, will activate alarm module 48, optical sensor 46, module 18, the valve 28 and the pump 34. At that time, valve 28 will be moved to its open position. The operation of the pump 34 draws liquid from the container 12 by way of the tube 16, port 20, valve 28, tube 31, port 24, tube 35, optical sensor 46 and tube 32. The pump 34 discharges the liquid therefrom by way of the discharge side 36 and hose or tube 38 into the receptacle 40. At a predetermined time, as controlled by controller 58, the system will halt the pumping of liquid into the receptacle 40.

If the container 12 becomes empty or some malfunction occurs in the system, the flow of liquid to the pump 34 will be disrupted. When such disruption of flow occurs, the optical sensor 46 will sense the disruption of flow through the optical tube 84. The change in the flow or liquid through the optical tube 84 of optical sensor 46 will cause the visual, data and audible signaling devices to be activated. The controller 58 will then close valve 28 and shut down pump 34. The visual, data and audible devices will alert the operator or attendant that a disruption has occurred. The controller 58 may also alert personnel by cell phone or other means that the disruption has occurred.

The attendant will then place a filled liquid container in place and connect the container to the module 18. The attendant will then press the reset button 56 to restart the system.

The system of FIG. 2 is identical to the system of FIG. 1 except that a second liquid container 12′ will be placed into the system. Container 12′ is fluidly connected by tube 65 to the second liquid intake port 22 of the module 18 and the valve 30 will become functional. The containers 12 and 12′ will normally contain the same liquid but they could contain different liquids. Thus, the controller 58 may place either bottles 12 or 12′ into operation. Normally, the container 12 will be in operation before the container 12′. At any time, the controller 58 may switch the system taking one container out of operation and placing the other container into operation.

Thus it can be seen that the invention accomplishes at least all of its stated objectives.

Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
