Definitions

  • the invention relates to an electronic dispenser of nebulized liquid products, such as perfumes and/or deodorizing, disinfecting or medicinal products, especially suitable for installing in the passenger compartment of cars and other motor vehicles.
  • the dispenser according to the invention is characterized by small size and by the use of replaceable or refillable canisters containing the product to be dispensed, which are not under pressure and are therefore safe and environmetally friendly.
  • the pump that dispenses the product contained inside the canister is actuated by an electromagnet, whose power and progressive action simulate perfectly the action of a person's finger, thus ensuring that the product dispensed through the pump is completely nebulized.
  • the dispenser has means for adjusting and programming the interval of time that lapses between successive dispensed doses of product, and has signalling means to warn the user when the canister is nearly empty.
  • the dispenser comprises a section 1 containing the entire electronic programming, controlling and signalling components of the device, and a section 2 containing the electromechanical part which dispenses the product.
  • the said two sections 1 and 2 are assembled in a single body 3.
  • the said two section may be separated, and connected only through electrical cables, and thus for example section 1 may be fitted to the dashboard of the motor vehicle, and section 2 may be installed anywhere in the passenger compartment of the motor vehicle.
  • the section 2 of the device contains a pushing electromagnet 4 having a fixed body (see below) arranged preferably with its axis parallel with the longitudinal direction of the container 3, and mounted on its movable member is a flanged disc 5 into which the base of the canister 6 containing the liquid product to be dispensed is inserted and centred.
  • the axis of the canister 6 is also parallel with the long dimension of the container 3.
  • the cannister 6 is in communication with the pump 7 that dispenses through the spray nozzle 45 the doses of product. With particular reference to Figure 3, the pump 7 will be described.
  • the said pump comprises a cylinder 107 closed at one end, and provided at the opposite end with a port through which the rod 46 of a piston 47 slidably mounted in the cylinder 107 is passed.
  • the cylinder 107 is further provided near its closed end with a radially projecting nozzle 45, communicating with the cylinder 107 in the manner which will be described later.
  • the closed end of the cylinder 107 is centred in a seat 8 formed for example integrally with a wall of the container 3 and provided with a projection 108 that engages a corresponding recessed part 48 of said cylinder 107, so as to assure that the nozzle 45 be pointed correctly towards a window 9 formed in the side wall of the container 3.
  • the numeral 10 indicates an annular seal disposed around the nozzle 45 in the region of the window 9, in order to insulate these means from the internal volume of the container 3.
  • the rod 46 of the piston is made tubular, and is provided at an intermediate portion with a flange 49 bearing against the outer surface of the bottom wall of the cannister 6.
  • the said rod 46 penetrates through a boring in the bottom wall of the cannister 6 into said cannister, and is provided at its free end with a tubular extension 207 formed by a flexible tube extending in the bottommost part of the canister 6 in order to ensure that all the product contained inside the canister be dispensed.
  • the piston 47 in turn, is provided with an axial through-boring, communicating at one end with the tubular duct of the rod 46 through a suitable non-return valve 50 urged by spring means against a valve seat, and at its other end with the cylinder 107.
  • the piston is constantly urged in one direction by a spring 51 disposed between the piston head and the bottom wall of the cylinder 107.
  • a second non-return valve 52 is disposed so as to close the port 53 between the cylinder and the spray nozzle 45.
  • the container 3 will be provided with a door (not shown) and all such means as will simplify insertion and removal of the canister 6 into and from its use position.
  • the dispenser is installed in the passenger compartment of the motor vehicle in a horizontal or inclined position, though always with the window 9 pointing down, or else in a vertical position, in which case there is no restriction as to the direction in which said window points.
  • the canister 6 is moved towards the cylinder 107 which is held stationary by the seat 8, thereby executing the compression stroke of the pump 7 and consequently dispensing through the nozzle 45 and through the window 9 a dose of the product contained inside the canister.
  • the electromagnet 4 is de-energized, the spring means 51 of the pump 7 return the piston 47 to its starting position, thus sucking through the tubular extension 207, the hollow rod 46 of the piston, and the non return valve 50 a new dose of product in the cylinder 107.
  • the electromagnet 4 is returned to the rest position.
  • the unit 7, 107 is not in line with the axis of the body of the canister but located in the bottom of the canister in a horizontal position so as to be very close to the window 9.
  • the electromagnet 4 may for example be securely fitted by means of its own body in a housing defined by projections 11 integral with a wall of the container 3 and is held in this housing by a band 12 fastened by means of screws 13.
  • the piston 47 of the pump 7 must be able to be worked by a great enough force, progressively, so that the product dispensed is completely nebulized.
  • this component has been carefully designed and its construction will now be described with reference to the detail of Figure 2.
  • the numeral 14 indicates the can of insulating material, wound around which is the coil of enamelled copper wire 15, which is then enclosed in the casing 16, integral with which at one end is a fixed ferromagnetic core 17 which extends a certain distance into the axial cavity of the can, where it terminates in a tapered frustoconical end 18.
  • the ferromagnetic core 19 Mounted so as to slide in the other free part of the axial cavity of the can is the ferromagnetic core 19 whose inner end is a frusto-conical recess 20 complementary to the end 18 of the fixed core.
  • the movable core is guided by the parts 21, 22 and is also guided by a ring 23 of a non-magnetic material located on the base of the casing 16, in which it is locked by a springy ring 24.
  • the electromagnet When the electromagnet is at rest owing to the action of the springy means 51 of the pump 7 of the canister 6, the disc 5 is pressed against the fixed core 17 and the movable core is in the position of maximum distance from the fixed core and of maximum extension from the assembly 14, 15.
  • the coil 15 When the coil 15 is energized, the movable core 19 is attracted into the can both by the direct action of the magnetic flux produced by the electric current passing through the coil, and by the force of attraction which this flux creates between the ferromagnetic parts 17 and 19, whose opposing inner surfaces are of opposite magnetic polarities.
  • the conical shaping 18 and 20 of the two cores 17 and 19 has the dual function of augmenting the surface area by which the two cores attract each other and of making the strength of this attraction more gradual and suitable for the purpose in question. If the dimensions of the play between the movable parts 19, 21 and the associated fixed guiding parts 14, 17 are properly calculated, it will be possible to achieve a choking effect that will suitably control the outflow of air from the chamber 114 during the active stroke of the core 19, in order to ensure a gradual actuation of the pump 7 and complete nebulization of the product which the latter dispenses as a result of the energizing of the electromagnet 4.
  • the electromechanical dimensions of the electromagnet are not considered here as these may vary as a function of the elastic properties of the pump 7 and because they can easily be worked out by those skilled in the art.
  • Figure 2 shows that the electronic part assembled in section 1, and entirely of low-consumption MOSFET technology, comprises a timer that can be programmed from 10 minutes to 99 minutes.
  • the program can be selected manually by pressing the cylinders 125 and 126 of the blocks 25 and 26 and is passed to the timer 27 by the logic switches 28, 29.
  • the block 27 repeats this until the program is changed.
  • the timer 27 produces a pulse which temporarily triggers the two monostables 30, 31, the last of which sends a control signal to the transistor 32 which passes the necessary current through the electromagnet 4 to activate the pump 7 and dispense one dose of product, as already discussed with reference to Figure 1.
  • the monostable 30 sends a control signal to the decoder-driver 33, 34 which shows in the low-consumption display 35, 135 a value representing the time programmed in. After a few hundred milliseconds, the function of 31 terminates and after one minute that of 30 also terminates.
  • a counter formed by the components 37, 38 with their memory unit 39 senses the number of actuations of the electromagnet 4 and when this number approaches a predetermined number stored in block 39, corresponding to almost complete exhaustion of the product in the canister 6, it illuminates a yellow LED 40 indicating the reserve level and the need to replace the assembly 6, 7 in the near future.
  • FIG. 41 indicates, purely by way of an example, a possible mounting in volume 1 of the aforesaid LEDs 40, 42, 43, the two displays 35, 135 and the cylinders 36, 41 and 125, 126.
