Definitions

  • the invention firstly relates to an improved device, of the pump or compressor type, for the suction and delivery of a fluid.
  • Such devices are known and usually include a rod system connected to the motor for driving, in a reciprocating motion, a means forming a piston in a pumping chamber.
  • These connecting rod systems appear in particular bulky and impose a relatively bulky overall shape of the device.
  • One of the problems posed in the present case is therefore to produce a fluid dispensing device which has a minimum bulk, in order to be able to be easily integrated into an apparatus supplied with fluid (without having to increase the dimensions of the latter).
  • the coupling means are movable in a relatively small displacement volume, centered on the axis of the device and allow a substantially coaxial mounting of the main organs of the dispenser.
  • the latter is thus particularly compact.
  • the invention also relates to an apparatus for dispersing or diffusing a liquid thanks to the fluid (gas) supplied by the device which is integrated therein.
  • the device in particular, use of the device as a room fragrance diffuser.
  • a complementary characteristic of the invention provides that the outlet passage of the cartridge which can extend the reservoir on one side, will preferably have a convergent / divergent form, the gas blowing duct and the liquid supply means then advantageously interrupting, in the tank, at a level where the passage in question will be convergent.
  • Another characteristic provides, still for this diffusion efficiency, that the device has a blown secondary gas conduit (in particular air) passing through the support body of the device to open around the outlet passage of the cartridge.
  • a blown secondary gas conduit in particular air
  • the apparatus of the invention having been designed so that the quantity of liquid to be dispersed can be easily modulated, another characteristic provides for the integration of a programmable electronic card for controlling the operation of the dispensing device. gas, by triggering and sequentially interrupting the supply of gas to the liquid diffusion means.
  • the device or means for distributing fluid advantageously consists of a pump or compressor of generally elongated shape (and essentially non-angular) along an axis 200 for pumping various fluids , liquids or gases, especially air.
  • This compressor 9 comprises an electric motor 204, a means forming a piston 206, 252 driven by the motor, in an axial reciprocating movement, inside a body 202 (of axis 200) essentially hollow to delimit, with this body , a pumping chamber 208.
  • This chamber communicates, via an inlet orifice 212, with a source of fluid 25 and with a discharge orifice or evacuation duct 21.
  • Means for selectively closing the passages 212, 21 are also associated with this chamber 208.
  • the general operating principle of the pump 9 is such that an axial movement (without rotation) in the direction of the arrow 216 of the piston means causes an increase in volume of the chamber 208, while the selective closing means maintain the fluid inlet passage 212 open and discharge passage 21 closed.
  • a reverse translation movement (arrow 218), the piston means exerts a pressure on the fluid contained in the chamber 208, while the closing means uncover the conduit 21, for the delivery of the fluid, and keep the orifice closed. 212.
  • the body 202 of the device here made of rigid plastic, comprises several essentially hollow and coaxial parts 224, 226, 228, cooperating with each other by defining a cavity 250.
  • the end piece 224 covers the end of the motor leaving its electrical terminals 232, 234 accessible for supply by a preferably autonomous stabilized source, for example at 6, 9 or 12 volts, such as a battery 27.
  • the motor / piston coupling means in this case comprise a metal head 236 provided with a guide path 238 formed on its peripheral external surface and angularly spaced, at least in places, from a plane normal to the axis 200, as well as a drive member 240 adapted to move along the path 238.
  • the head 236, mounted on the drive shaft 242 of the motor, here has the general shape of a directing cylinder (preferably straight) circular and is rotated (in a given direction) around axis 200.
  • the guide path is continuous, closed on itself and essentially follows an oblique path relative to the axis 200. It advantageously consists of a groove or groove 238 formed on the tubular face of the head and having here the general shape d 'a ring essentially inscribed in a plane which forms with the straight line 200 an acute angle ⁇ greater than about 70 ° and less than 90 °.
  • the drive part 240 can consist of a metal pin provided with a pin 240a capable of being introduced with a slight play in the groove 238, while being able to rotate in a part 206 to which it is linked.
  • the coupling means mechanically balance themselves, which is certainly favorable to the efficiency and reliability of the device and to obtaining high fluid flow rates for low consumption.
  • the piston means here comprises the sliding part 206, of circular cylindrical shape, which is hollowed out, at 246, from one of its ends 206a, the open clearance 246 having a shape suitable for the part 206 to be mounted, relatively tightly , on the head 236 with possibility of sliding.
  • This sliding part also comprises, formed in its wall, an opening 248 for housing the pin 240, substantially normal to the axis 200.
  • this piston 206 moves closely essentially in the tubular element 226 of the body 202.
  • This element 226 which is linked at each of its ends to the elements 224 and 228, has an essentially cylindrical inner wall which goes away flaring towards the end 226b for fitting element 226 into element 228, following a surface concavity curve facing the cavity 250.
  • the pumping chamber 208 it is here defined essentially by the piston-forming means, the terminal portion with an inner flared wall of the part 226, and by the element 228.
  • This element 228 has a general form of cap with a part transverse end. 225 extended by a substantially cylindrical tubular skirt 227 of generator parallel to the axis 200, the part 225 having an inner face 225a curved, with concavity turned towards the chamber 208.
  • the latter comprises a fluid-tight membrane 252 which participates in pumping the fluid. This membrane is kept pressed in its central part (substantially perpendicular to the axis 200) against the transverse end face 254 of the piston 206 with which it moves, by a locking disc 264, screwed.
  • This flexible and deformable membrane is advantageously in a natural, unconstrained state, like a disc, plane or curved, with a diameter greater than the cross section of the piston and, here, also greater than the internal diameter of the parts 226 and 228, to advantageously ensure sealing at the level of the fitting zone of these parts 226 and 228.
  • this membrane will be chosen to be thin, with a thickness for example of between a few tenths of a millimeter and a few millimeters (advantageously less than 2 mm) to reduce the resistive torque of this membrane and apparently make it possible to obtain a high flow rate of fluid for low engine consumption.
  • the membrane will be produced by cutting a disc in a sheet, or a tube, from a rubbery elastic material, such as an elastomer.
  • the membrane is fixed to the block 206, once the latter has been placed in the element 226, then is tensioned suitably on the circular end 226b and is here held there by a clamping ring 262.
  • the periphery of the membrane extends against the external interlocking face of the element 226 and then allows a tight connection with the element 228.
  • the peripheral edge of the membrane could be directly kept linked to the body 202 by being clamped and locked between the external and internal faces of fitting elements 226 and 228.
  • this membrane which is fixed relative to the body at its periphery, in this case constitutes the means for locking in rotation relative to the body of the piston-forming means.
  • at least one longitudinal projection and a complementary axial groove could be provided, formed on the part 206 and the element 226.
  • passages 212 and 21 for circulation of the fluid they are in this case formed in the wall of an end piece 230, here essentially full, of the body 202 and in the wall of the part 225 of the element 228, these parts 228 and 230 being fixedly connected by any known fixing means, with interposition between them of the means for selectively closing the orifices 212 and 21, taken closely as a "sandwich".
  • These selective closing means comprise in this case two one-way valves constituted by the tongues 220 and 222 (for example made of fluid-tight rubber).
  • the block 206 is brought back by the drive member, along arrow 216, in the direction of the motor. This creates a depression in the chamber 208 and allows it to be filled.
  • the piston-forming means performs a round trip per revolution of the head 206.
  • a guide path could be designed with a wavy line.
  • the inventors have found that it is possible to obtain high flow rates of fluid, in particular gas, for low pressures and this with low consumption of the engine.
  • gas flow rates of 1.8 liters / minute (on average between about 1.5 and 2 liters / minute) for a pressure of about 200 to 400 millibar, the engine supply (turning for tests between 5000 and 6000 revolutions / minute) being less than 250 milliamps (around 200 milliamps) in 6 Volts.
  • the device 9 could be used for pumping liquids or gases and could advantageously be integrated into the diffusion device 1 shown in FIG. 1. Still within the scope of the invention and to obtain high fluid pressures (greater than 1 bar), a membrane with a thickness greater than 2 mm may be used (for example up to 4 mm) and in the case of liquids, it might be possible not to provide a waterproofing membrane.
  • the device 1 is used to disperse a liquid, such as for example an eau de toilette 3, contained in a refill cartridge 5 (FIG. 2).
  • a liquid such as for example an eau de toilette 3, contained in a refill cartridge 5 (FIG. 2).
  • the device 1, or sprayer essentially comprises a support body 7 made of plastic, containing, in the lower part, the distributor 9 (here gas, in particular air) and, in the upper part, a distribution barrel 17 internally defining a housing 11 for a removable cartridge 5, so that its discharge opening 13 (FIG. 2) is, once the cartridge in place in its housing, extended by an outlet passage 15 defined by the internal conformation of the barrel 17, an interior chamber 19 ensuring in particular the communication between the outlet 21 of the device 9 and the inlet channel 23 of the cartridge 5.
  • the distributor 9 here gas, in particular air
  • the outlet passage 15 will advantageously have a form of convergent / divergent, with successively a convergent 151, an area of constant section 152 and a divergent output 153.
  • the location 11 for the cartridge 5 and the discharge passage 15 which extends it may be surrounded by a channel 29 connected upstream, via a calibrated tube 31, to the chamber 19 and opening downstream around the divergent 153, so that circulates in this passage 29 a secondary gas (air) promoting the dispersion of the main gas (air) flow carrying the liquid to be "vaporized".
  • the flange 153 will be removable and the barrel 17 will have a fixed base 171, in which will be hollowed out the housing, for example parallelepipedal open on its upper face and having an orifice 111 in its opposite lower face for the passage of the nozzle 23, the upper part 172 of the barrel being removable and can for example be made in two half-shells.
  • plastic cartridge-refill 5 of FIG. 2 it can consist of a tank base 33 containing the liquid 3 and surmounted by an outlet neck 35 having a converging part, then an end part of reduced section neck constant 351 corresponding substantially to the reduced section s of passage 15.
  • the cartridge 5 also contains the diffusion means 37 which will therefore advantageously make it possible to disperse the liquid in a very fine mist, all the more easily since this liquid is volatile.
  • the means 37 comprise a single plastic part fixed at the bottom to the base 33 of the cartridge which it passes through to present the abovementioned connection end piece 23.
  • the part 37 has a gas blowing duct 39, which opens in the upper part, above the level L of the liquid, as well as a second duct 41, of reduced section compared to the first, communicating in the lower part with the liquid and opening, in the upper part, facing the first conduit 39, these conduits 39, 41 being calibrated.
  • the capillary duct 41 may for example have an internal diameter of the order of 0.4 mm, for an upper section of the channel 39 which may be between 0.65 and 1.2 mm approximately.
  • the channel 39 will be interrupted, in the reservoir, at a level close to the narrowest end of the converging part of the neck 35, to blow the gas flow received substantially in the vertical central axis 43 of the cartridge. .
  • FIG. 3 shows a possible electrical diagram of this card which could be a programmable card, making it possible to control the operation of the means 9 by triggering and sequentially interrupting the distribution of the gas to the diffusion means 37.
  • the card 45 will be essentially constituted on the basis of an electronic timer, of which we will first consider the outputs 1 and 5 of the eight switches 47.
  • the output 53 of the inverter 55 is at logic level 1.
  • This initialization (reset) when the under tension is then applied to the two flip-flops 57, 59, as well as to the pulse counter 61 (in this case of the "4040" type).
  • the counter as well as the two flip-flops 57, 59 are therefore at logic level 0.
  • the terminals 63 and 65 respectively of the counters 57 and 59 are at level 1: the light-emitting diode (for example red) 67 is then lit and the distributor means for gas 9, connected to connector 69, does not work, no spraying of fluid then existing.
  • the capacity 71 is discharged.
  • a logic level 0 is therefore applied to the input 73 of the second inverter or trigger 75 whose output 77 is then at level 1.
  • This pin 77 then being at 9 volts, the capacitor 71 is charged by the resistor 79 in series with a potentiometer 81.
  • the capacitor 71 discharges into the resistor 79 and the potentiometer 81. Once its voltage is sufficiently low, the inverter 75 switches again, and so on.
  • the inverter 75 is therefore a clock.
  • the output 1 of the series of switches 47 is assumed to be conducting; after 16 pulses on the clock input of counter 61, its output 99 goes to 1. A rising edge is applied to the clock input 101 of flip-flop 59, its output 103 passing to 1, while its exit 65 is no longer busy. The distributor 9 is then no longer supplied, the lighting changing from green to red (diode 67).
  • Counter 83 still counts.
  • the pulses sent to the input 89 of the flip-flop 57 are not taken into account because the pin 87 (reset) is always at 1.
  • Switch 5 of the series of switches 47 is closed.
  • After the 256th pulse on the clock input of the counter 61 its output 105 goes to 1.
  • the output 116 of the trigger therefore goes to 1.
  • the counter 83 is initialized by pin 119 of flip-flop 57, its outputs being at 0. At the first clock pulse, its output 85 goes to 1, flip-flop 57 taking into account the rising edge. and the cycle begins again.
