- a serial bus port 52 for the transfer of data between the CPU 46 and the memories 28a, 28b, 28c, 29a, 29b, 29c of the reservoir 2, 3 (reading the data contained in these memories, sending signals for the destruction of tokens, etc.), each memory having an address given to it by the location of the reservoir in the device, an input / output port 54 for the transfer of data between a keyboard 44b accessible by the user and the CPU 46, and thus between the solenoid valve system 19 and said CPU 46 via a power stage 63, - an input / output port 49 for the transfer of data between the remote control means 45 and the CPU 46, the preceding elements being, in a known manner , connected together by a bus called backplane bus comprising a power bus 56, connected to the mains or to a battery 65 by means of a power supply stabilizer 60, and by a control bus 57 , an address bus 58 and a data bus 59, for data transfer.
- backplane bus comprising a power bus 56, connected to the mains or
- the device comprises means for measuring the quantity of fluid present in each tank, such as an electric gauge for example.
- These means can be carried by the reservoir 2, 3, 4 or associated with it during its installation in the device.
- the measurement of the quantity of fluid can be continuous or periodic.
- each reservoir comprises, among its storage means 28, 29, 30, a memory accessible in read and write (of the EEPROM type) in which the quantity of fluid present in each tank, as determined by the corresponding measuring means, is constantly or periodically stored.
- the quantity of fluid measured by the measurement means is recorded in a memory accessible in read and write of the control means 1, with reference to the reservoir concerned.
- the memory 28b, 29b of the reservoir 2, 3 comprises for example a prerecorded identification number of the reservoir, which is used as a reference when the value of the quantity of fluid is recorded in the memory provided for. this effect.
- Each new measurement of the quantity of fluid in a reservoir is compared with the last measurement stored in said memory. If the new measurement is less than the last measurement, the latter is recorded in place of the last measurement. Otherwise corresponding to an increase in the amount of fluid present in the reservoir, the control means 1 are adapted to control the closing of the solenoid valve (system 19) controlling the air supply to the spraying member. 11, 12, 13 associated with said reservoir, and said last measurement is not recorded in the memory provided for this purpose. In the particular case where the last measurement is zero (empty tank), the control means 1 also controls the closing of the solenoid valve and the measurement is recorded. This embodiment makes it possible to detect in real time the filling of a reservoir by the user and to immediately inhibit the diffusion means associated with the reservoir.
- the spraying member associated with a reservoir is integral with the latter and therefore removable.
- said spraying member is fixedly mounted at the end of the pipe 14, 15, 16 for outputting the mist of microdroplets, and only the reservoir is removable.
- only a part (venturi for example) of the spraying member is integral with the reservoir and therefore removable.
- the memory 28b, 29b dedicated to the information relating to the reservoir includes data defining the diffusion means carried by the removable reservoir and allowing the control means 1 to check the compatibility of said means with the diffusion means already present on the fixed part of the device of the invention.
- a plurality of removable tanks is connected to a single spraying member, by means making it possible, according to predetermined conditions and under control of the control means, to authorize or prohibit the fluid contained in each tanks access to the spraying device.
