In Figs. 1a and 1b, the cover 1 has been shown transparent so that the internal organs of the device can be viewed. These figures show the cover 2 of the cover 1, provided with a display screen 3. Furthermore, through the cover 1, the waste receptacle 8 for the rinsing water and the empty capsules of components assets.

The lid 2 finally has a slot 9 for the introduction of one or more capsules of active components in a receiving chute 10. These capsules each contain an active component which will be mixed using the device with one or more components. base contained in pots 11 installed in the device by the user, for example by quarter-turn screwing, after opening the lid. The capsules of active components, and possibly the pots of basic components, are identified by color codes detected by optical detectors 12 (FIG. 18) connected to a microprocessor 13. The microprocessor 13 controls the assembly 14 of the motors of the device, 25 as well as the water pump and the display screen 3. Reference will now be made more particularly to FIGS. 2 and 3. It is firstly seen in FIG. 2 the three motors 20, 21 and 22. FIGS. 2 and 3 show two Peltier cooling and ventilation modules 24 for the refrigeration of each of the pots of basic components 11. Such elements are known per se, as are their control and their mode of operation. operation. They will not be described in more detail.

3031463 7 As shown in Figure 18, they are controlled by the microprocessor 13. Finally, we see in these figures the support 25 pots base components 11, which will be described below.

Figure 4 shows the base support member 25 and its drive means. The output shaft 21 of the motor 21 is provided with a toothing which meshes with a toothed wheel 31 which rotates, about a shaft 32, of the support 25 of the pots of basic components. Thus, the motor 21 rotates the support 25 of the basic component pots around the axis of the shaft 32. The output shaft of the motor 20 carries a pulley 36 capable of driving another pulley. 37 mounted on the shaft 32, by means of a belt not shown. The shaft 32 consists of an endless screw cooperating with a threaded bush 38 secured to the support 25 of the pots of basic components. Thus, the motor 20 makes it possible to drive the support 25 of the base component pots in a translation movement parallel to the axis of the shaft 32. In this movement, the support 25 of the basic component pots is guided by stems 39.

Referring now to FIG. 5, the motor 22 and its function. The output shaft 40 of the motor 22 carries a pinion 41 which meshes with a toothed wheel 44. The toothed wheel 44 rotates about an axis 45, diametrically opposite, two supports 46 of connecting rods 47. Each connecting rod 47 carries at its end a piston 50 engaged in a respective cylinder 52, 53 formed in a mixing block 51. Thus, the motor 22 rotates the toothed wheel 44, and through it the pistons 50 in opposite reciprocating motions in the 30 cylinders 52, 53 of the mixing block 51. It can be seen in FIG. 6 that the mixing block 51 comprises two cylindrical ducts 54 and 55 in which are respectively housed a main valve 56 provided with three bores and an auxiliary valve 57 provided with a piercing.

The main valve 56 is rotated by a pinion 58 meshing with a toothed wheel 59 mounted on the output shaft of a motor 60. The auxiliary valve 57 is rotated by a system of links 61 actuated by a motor 62.

As shown in FIG. 9, the support 25 of the base component pots 11 forms, for each base component pot location, a tip 80 capable of sealingly fitting an orifice 81 formed in the wall of the base component pot. cylinder 52 of the mixing block 51. The orifice 81 permits the flow of the contents of the basic component pot into the cylinder 52. FIG. 6 shows a hollow needle 90 carried by a syringe. The hollow needle channel 90 corresponds to a duct 91 (FIG. 7) formed in the wall of the mixing block 51. The duct 91 opens into the cylinder 53 through a hole in the main valve 56 when the latter is placed in the proper angular position. In another angular position of the main valve 56, a washing channel 92 is placed in communication with the mixing block. In a third position of the main valve 56, the cosmetic product can be supplied to a user via a delivery nozzle 20 of the cosmetic product, and in a last position the main valve 56 closes the various orifices. Referring now to FIGS. 10a, 10b and 10c, it can be seen that the receiving chute 10 is pivotally mounted on an axis 100. It furthermore comprises a stop 101 capable of rotating it about its axis when this The abutment is pushed by a protrusion 102 of the support 25 of the pots of basic components. In this movement, the active component capsule 103 located at the bottom of the receiving chute 10 is perforated by the hollow needle 90, so that the active component it contains can be sucked through this needle.

These same figures show the ejector 104 of empty capsules mounted on a pivot 105. This ejector consists essentially of a rod carrying at one of its ends an ejection finger 106, and at its other end an actuating stop. 107, capable of rotating it when this actuating stop is pushed by the projection 102 of the support 25 pots of basic components.

The operation sequencing of the device will now be described, more particularly with reference to FIGS. 10a to 16. This sequencing is performed by the microprocessor 13. The first phase of the process consists in introducing one or more doses of active component into the device. cylinder 53 of the mixing block 51. In a first step, the orifice of the main valve 56 intended for the suction of the asset is put in place in front of the orifice of the needle by means of the motor 60. (Figure 11). The second step consists in putting the auxiliary valve 57 in the cap position using the motor 62, so as to close the orifices 110 (FIG. 8). The piston 50 of the cylinder 53 is then fed by the motor 22 in the bottom course, as shown in FIG. 12. In the third step (FIGS. 10a and 10b), the support 25 of the basic component pots is operated by the motors 20 and 21 so that the projection 102 rotates the receiving chute 10. The needle 90 thus pierces the capsule 103. The motor 22 is then activated so that the piston 50 of the cylinder 52 sucks the contents of the capsule 103 in the cylinder 52. - The fourth step is to eject the empty capsule 103 25 in the waste receptacle 8. This is done by the motor 21 which moves the support 25 pots of basic components so that the protrusion 102 contacts the actuating stop 107. The third and fourth steps are repeated as many as 30 times as there are capsules 103 in the receiving chute. The second phase of the process consists of dosing the basic component or components (FIG. 13). - For this purpose, the main valve 56 is put on the position 35 closing with the aid of the motor 60 and the auxiliary valve 57 is put in the closed position by means of the motor 62. 3031463 10 - With the aid of the motor 21, the base support has the tip 80 of the pot in front of the base dispensing orifice 81, and with the aid of the motor 20 and the worm 32, pulses are made on the pot to dose the base.

The motor 22 is then actuated to deliver to the cylinder 52 the amount of base component selected. -The third phase of the process consists in mixing the basic components and the active components. For this purpose, the auxiliary valve 57 is put in the open position by means of the motor 62. The motor 22 is then actuated so as to pass alternately, by the opposite movement of the pistons 50, the mixture of components of the cylinders 52 to 53 through the conduit 55 (connecting the two orifices 110), which creates disturbances 15 achieving a homogeneous mixture (Figures 14a and 14b). - The fourth phase of the process is to distribute the product manufactured to the user. - The first step is to bring the mixture to the cylinder 52 with the motor 22 (Figure 15). 20 - The secondary valve is then closed (Figure 16). - The motor 22 is actuated so that the piston 50 ejects the product through the nozzle 93. This operation can be triggered by the optical detection of the hands of the user. At the end of the cycle, cleaning of the device is performed by nozzles 25 fed by the water pump. The cleaning water is collected in the waste compartment.
