Abstract

This invention relates to a flushometer for toilet or urinal driven with an electronic valve fed with a dry cell. Which is activated electronically when perceiving an object or a person at a pre-established distance. The object of this invention is to provide an electronically operated flushometer whose power source is independent of the electrical current.

Description

•• IMPROVEMENTS IN FLUXOMETERS FOR TOILETS AND MINGITORIES, POWERED BY ELECTRONIC VALVE POWERED BY PILA " BACKGROUND OF THE INVENTION The flushometers that are installed in the bathrooms of public buildings and in some Institutions of the sector Health, they are operated with levers, pedals, buttons and in some cases they are powered by an electronic valve powered by electric current. So if the person who makes use of the toilet or urinal does not operate the lever, pedal or button; the toilet or urinal remains as a source of infection and bad smells. And in the case of the flushometers powered by an electronic valve powered by electric current, when there are faults in the electrical current, the flushometers are not activated, leaving the source of infection and bad odors. Therefore the present application was developed, since it is a flushometer for toilets and urinals, operated with an electronic valve fed with a dry cell.

DESCRIPTION OF THE INVENTION The present invention relates to a flushometer for toilets or urinals, which unlike those already known, is automatically activated by an electronic sensor, connected to an electrovalve and also the energy to activate the sensor and the solenoid valve is supplied by a dry battery.

SHEET - l - As it is known, flushometers for toilets or urinals are water dosing valves, used for cleaning sanitary furniture; The fluxometers that were initially manufactured are operated by manual mechanisms such as: pedals, buttons and handles.

Subsequently, the flushometers were activated by electronic sensors connected to a solenoid valve and a 120-volt electrical network. The fluxometers operated by mechanical means are new for the operating cycle they present, since to work it is necessary to break the hydrostatic balance presented by the flow control plunger of the flushometer, this balance is broken by moving a rod that protrudes from the plunger of flow control with which water is allowed to leave the chamber of the dome of the flushometer. When water comes out of the chamber of the dome, the plunger moves allowing the passage of water to the cabinet; When the chamber of the dome is filled with water again, the plunger is displaced blocking the passage of water to the sanitary furniture. The present invention has the advantage over the flushometers operated by mechanical means that the drive is performed automatically and electronically; and has the advantage over those driven by electronic sensors connected to a solenoid valve and a 120 volt electrical network, that the power supply to the electronic system is carried out by means of a dry battery, for which no electrical installation is required.

The details and characteristics of this fluxometer are clearly shown in the following description of the accompanying drawings. Figure number 1 is a perspective where the electronic elements of the model can be clearly seen in detail with their proportional design tracings. Figure number 2 is a top view of the aforementioned design. Figure 3 is a front view in section, showing the operating mechanism of the flushometer in the closed position. Figure number 4 is a front view in section, showing the operating mechanism of the flushometer with the activated solenoid valve, diaphragm, actuator piston and discharge piston. Figure number 5 is a front view in section, where the operating mechanism of the flushometer with the displaced main piston is shown, whereby the discharge is directed to the toilet or urinal. With reference to said figures, in figure 1 the electronic control card (b) is shown, composed of the following main parts: a sensor (a :), a pilot focus (c) and a potentiometer (h). Also shown is a housing (e) housing the electronic system and the power system, a battery (g), a battery holder (f), a battery cover (i) and a cover (d) to cover the electronic system The sensor (a) is composed of an infrared ray emitter (invisible to the eye) and a receiver thereof, the range length of the infrared ray can be regulated by the potentiometer (h) placed on the electronic card (b). The cycle begins when the sensor perceives an object or a person by reflecting the infrared ray emitted by the emitter of the sensor (a), and the flushometer will discharge under the following condition: The object or the person must remain 10 seconds as minimum in front of the sensor. The flushometer performs the discharge when the object or the person is removed from the sensor as indicated: First the solenoid valve is activated releasing the central hole of the diaphragm (t), as shown in figure 4, the water that was in the camera (p) passes to the camera (j) and immediately the diaphragm (t) is driven by the new pressure difference of the water contained in the chamber (m) and in the chamber (p), therefore the water continues its passage from the chamber () to the chamber (j), displacing the actuator piston (k). In its stroke the actuator plunger (k) causes an oscillatory movement to the discharge valve (1), and with this movement the water contained in the chamber () is released, generating an inequality of pressures between the chamber (o) located in the dome of the flushometer (u) and the chamber (n), so that it moves upwards from the body of the flushometer (v) the flow control plunger (ñ), and the water passes to the toilet or urinal through the space that I let the flow control plunger (ñ) rise as shown in figure 5. Once the flow control plunger (ñ) is raised, the discharge plunger (1) returns to its closed position, by the direct action of the spring that is in the chamber (m) and the water continues to pass to the chamber (o) through a hole (9.) / generating greater pressure in the chamber (o) so that the flow control piston (ñ) tends to lower again, blocking the passage of water from the chamber (n) to the toilet or urinal, as shown in figure 3. The actuator piston (k) returns to its resting position after 2 seconds of being activated, since the solenoid valve is activated with opposite load and forces the core (r) to block the central hole of the diaphragm (), and the water in the chamber (m) continues to pass through the chamber (p) through two small holes (s), generating the necessary pressure to block the water flow from the chamber (m) to the chamber (j) and the spring of the actuator piston (k) returns it to its resting position.
