Definitions

  • the present invention relates to a sprayer of the type used in both agriculture and gardening, provided with an electric pump powered by a rechargeable electrical battery, to propel the product out, through a spear ending in the corresponding spray nozzle.
  • the object of the invention is to obtain a sprayer with optimal functional performance, that is, one allowing to perfectly control the amount of product to be dosed and also resulting in a reduced energy consumption, with the ensuing increase in sprayer operation time, that is, in the time periods between battery charging.
  • sprayers In spraying liquid phytosanitary products in the field of gardening and agriculture, sprayers are used which consist of a back-pack type tank loaded on the operator's back, from which a conduct emerges which through an opening and shut-off valve is connected to a nozzle by which the spray is produced and dosed on the plants to be treated.
  • a sprayer of this type is for example described in utility model no. 9302324 of the applicant.
  • utility model no. 9000610 also of the same applicant describes a opening and shut-off check valve for sprayers and the like, consisting of a long hollow body in which is housed a filter the front of which ends in a disc and the back of which is constantly pushed towards a set position by a spring, so that when it moves due to the action of the release lever it opens and liquid is allowed to pass from the conduct communicated to the tank to the tube with the spear ending in the spray nozzle, while when the lever is released the spring pushes the filter in the opposite direction, resulting in a liquid-tight seal which prevents liquid from passing.
  • the activation handle acts as a valve which opens or closes the liquid passage from the tank to the spraying spear.
  • these sprayers are naturally provided with a pressure pump to adequately pressurize the inside of the tank, so that the phytosanitary liquid leaves the tank with the required pressure.
  • Normally activation pumps are of manual type, operated with an external lever, while in the present for high-range sprayers electrical pumps are used, fed by a rechargeable electrical battery conveniently housed in the sprayer.
  • the sprayer proposed in the invention which incorporates an electrical pump as means of propulsion of the phytosanitary liquid, whether with glands or gears, and an opening and closing valve performing in the manner described in utility model no. 9000610, centers its characteristics in an electronic control system which on one hand provides a simpler and more efficient operation and also a substantial saving of energy.
  • the sprayer proposed is provided with an electronic control board to govern the electrical pump which in turn is commanded by a small electronic card located in the spear itself and related to the electronic control unit by cables housed in a tube placed parallel to and joint to the phytosanitary liquid outlet.
  • the electronic card placed in the spear includes a reed relay to activate the command circuit, which is performed with the aid of a magnet conveniently attached to the handle, said card also aided by two potentiometers, one to control the time of operation of the electrical pump, so that it operates at preset intervals set through this potentiometers, while the second potentiometer allows controlling the operation pressure, specifically acting on a chopper which chops the voltage signal acting on the electrical pump thus changing its velocity of rotation.
  • An LED diode mounted next to the aforementioned potentiometers on the base of the spear shows the charge status of the battery and together with a protection circuit for said battery prevents excessive discharging, which may damage it. For this reason, when the battery charge reaches a minimum preset value the LED lights and the electrical pump power is shut off, this situation being preceded by a blinking LED which warns of the need to recharge the battery.
  • the sprayer proposed consists of a tank (1) of adequate capacity, from the lower side of which emerges a conduct (2) for liquid outlet, obviously flexible, which in its free end ends in a spear (3) finished in a spray nozzle (4), said spear having a base (5) which makes up a handle provided with a lever (6) which acts as a valve element, allowing or not the liquid to pass outside, propelled by a classical electrical pump (7) fed by a rechargeable battery not shown in the figures.
  • the characteristics of the invention center on tank (1) incorporating an electronic control board (8) for the electrical pump (7), board (8) being connected by electrical leads (9) to a control card (10) placed in the base (5) of the spear, said cables (9) being housed in a hose (11) which lies along the outlet hose (2) for the liquid to which it is attached by one of its generatrices.
  • a single hose may be used with two inner conducts, one for the liquid and another for the electrical cables.
  • Control card (10) is aided by a reed relay (12) clearly seen in figure 3, by a pair of potentiometers (13) and (14) and by an LED diode (15), with a permanent magnet (16) aiding the reed relay, conveniently located in lever (6) opposite reed relay (12) as seen by the arrow in figure 2, so that when lever (6) swings towards the valve-open position relay (12) is activated and therefore electrical pump (7) is activated.
  • potentiometers (13) and (14) mentioned above the activation of electrical pump (7) is also controlled by control card (10) by potentiometers (13) and (14) mentioned above, of which potentiometer (13) acts as a timer device, automatically varying the dosing time of the sprayer when allowed by a general switch (17) which can enable or disable its timer function, while potentiometer (14) which acts as a pressure controller, does so by chopping the voltage signal acting on the motor thus varying its rotation velocity and therefore the pressure supplied by the electrical pump.
  • Potentiometer (13) acts on a timer so that after the time set is over the circuit cuts off power supply to the electrical pump interrupting the outlet of liquid.
  • the timer allows to continuously vary application time between 1 and 10 seconds regardless of the position of the other potentiometer that is, regardless of the pressure supplied at the electrical pump.
  • action of the lever is irrelevant, and it must be released to open the reed relay (12) and pressed again to begin a new application cycle which will last exactly the time set by the timer potentiometer.
  • Regulation by potentiometers (13) and (14) can be performed at all times, even during application, so that it is not necessary to stop spraying to change from one situation to another or to change the pressure or dosage time.
  • the sprayer is also provided with a battery protection circuit, with a warning system consisting of an LED (15), also associated to card (10), this circuit preventing an excessive discharge of the battery, specifically at a minimum charge of 10.2 volts, when power to the electrical pump is stopped and LED (15) indicates this situation by lighting, blinking first in order to warn that, although the sprayer is operational, it the battery is about to be exhausted and therefore its recharging is required.

  • the electronic sprayer of the invention incorporates the following advantages with respect to conventional sprayers:
