Description

ANIMAL FOOD DISPENSER

FIELD OF THE INVENTION

The invention relates to an animal feed dispenser. The invention particularly relates to a food dispenser for use in pet shops where the animals are raised in bins stored on shelves (or racks).

STATE OF THE ART

Some fish, such as zebrafish (Danio rerio), are increasingly used in research as model organisms. These fish possess an interesting genetic heritage with similarities to that of humans. In addition, zebrafish have excellent reproductive abilities and their embryos are transparent, making them suitable for use in optogenetics and optopharmacology.

These fish are usually raised in research laboratories, dedicated pet shops, or commercial pet shops, which can include several tens of thousands of individuals. In these pet shops, the fish are distributed in bins, the bins being arranged on racks. Each bin typically contains between one and fifty individuals.

Several times a day, operators must deliver food to the fish. The food may be solid food, in the form of powder or granules, or liquid food containing small living organisms (eg Artemia or Rotifera).

However, because it is done manually, the feeding is extremely long and tedious.

In particular, the liquid food must be delivered with the help of wash bottles. However, the repeated actuation of the washers by the operators over a prolonged period causes musculoskeletal disorders, severe inflammation of the arms, including tendonitis, and chronic pain in the arms and shoulders. Moreover, it is not possible to accurately control the amount of solid or liquid food delivered. This lack of control can lead to inadequate doses of food. However, an insufficient amount of food can cause growth problems in fish. On the other hand, a too large dose causes the food to be not entirely consumed by the fish and causes water pollution, which can also have a negative effect on the health status of the fish.

The document EP 2 263 452 describes an automated food distribution system in an animal facility comprising bins arranged in rows, not requiring direct intervention by an operator. The described system comprises a gantry formed of a series of vertical pillars and a horizontal beam, the gantry being installed in front of the rows of bins. The system further includes a carriage capable of moving along the horizontal beam (in a first horizontal direction X), a vertical rod attached to the carriage, and a food delivery device capable of moving along the rod ( in a second vertical direction Y). The food dispensing device can thus be moved motorized in the horizontal and vertical directions. The dispensing device includes a support head and a bottle containing food to be dispensed. The food distribution device is positioned successively automatically in front of each tray and the bottle is inclined relative to the support head by means of a motorized arm to pour food into the tray.

The advantage of such a system is that it allows to precisely control the amount of food distributed.

However, because of its large size, such a system can not be installed in all pet stores.

In addition, because of its complexity, the system is expensive and requires significant maintenance. This maintenance can only be performed by specialized technicians. Moreover, the distribution of liquid food requires in any case the presence of operators because the liquid food must be prepared at the last moment, just before distribution.

Finally, during feeding, operators usually want to be able to observe the fish visually, in order to be able to detect any anomaly or to make sure of their state of health, which is not possible with this system.

DETAILED DESCRIPTION OF AN EMBODIMENT

Figures 1 and 2 schematically illustrate a feed dispenser 1 for animals according to a possible embodiment of the invention.

In the embodiment illustrated in these figures, the food dispenser 1 has two configurations: a first configuration, illustrated in Figure 1, wherein the food dispenser 1 allows the distribution of solid food, such as food in form of powder or granules, and a second configuration, illustrated in Figure 2, wherein the food dispenser 1 allows the distribution of liquid food, such as food in the form of a solution containing small living organisms.

In the first configuration (Figure 1), the food dispenser 1 is formed of a control module 100 (or main module) and a first food distribution module 200, removably attached to the control module 100 . In the second configuration (Fig. 2), the food dispenser 1 is formed of the same control module 100 and a second food delivery module 300, different from the first food delivery module 200, and releasably attached to the control module 100.

Figures 3 to 6 show more precisely the control module 100.

The control module 100 has the shape of a gun. It comprises a handle 101 suitable for being gripped by an operator, and a housing 102 extending substantially perpendicularly to the handle 101.

The control module 100 further comprises an electronic control card 103, one or more battery (s) 104, a detection member 105, a light source 106, a reader 107 and a display screen 108.

The electronic control board 103 is housed inside the housing 102. The electronic control board 103 is electrically connected to the battery (s) 104, to the detection element 105, to the light source 106. to the reader 107, and to the display screen 108.

The handle 101 has a generally cylindrical shape. It comprises a cylindrical body 109 delimiting an internal cavity 110 and an opening 111. The internal cavity 111 is adapted to receive the battery or batteries 104 for supplying electrical energy to the food dispenser. The battery (s) 104 may be inserted into the internal cavity 110 via the opening 111. The control module 100 further comprises a spring 112 and a plug 113 for closing the opening 111. The battery (s) 104 are held in place in the internal cavity 110 between the spring 112 and the plug 113. The plug 113 can be fixed on the body 109 of the handle 101 by screwing. The plug 113 can be unscrewed to allow replacement of the battery (s) 104. As can be seen in Figure 4, the plug 113 further comprises a notch for inserting a screwdriver to facilitate unscrewing.

The control module 100 further comprises a first connector 114 also connected to the control electronic card 103. In the embodiment illustrated in FIGS. 3 to 6, the detection member 105 comprises a trigger 115 having a first end 116 extending inside the housing 102 and a second end 117 extending outside. of the housing 102.

The trigger 115 is rotatably mounted relative to the housing 102 at its first end 116. For this purpose, the control module 100 comprises a first part 118 fixed to the housing 102 and a second part 119 fixed to the trigger 115, the one of the first piece 118 and the second piece 119 having a groove 120 and the other of the first piece 118 and the second piece 119 having a pin 121 extending inside the groove 120. The pin 121 is rotatably mounted inside the groove 120.

In the embodiment illustrated in Figures 3 to 6, the second end 117 of the trigger 115 has a clean C shape to bear on an annular flange surrounding an opening of an enclosure containing animals.

However, the trigger 115 may be replaced by another trigger having a second end 117 of different shape. The first piece 118 and the second piece 119 form in effect a connecting mechanism arranged to receive interchangeably and indifferently a trigger of a first type or a trigger of a second type, different from the first type.

The detection member 105 further comprises a switch 122 housed inside the housing 102 and electrically connected to the electronic control board 103. The trigger 115 is mounted movably relative to the housing 102 between a first position in which the trigger 115 does not solicit the switch 122 and a second position in which the trigger 115 requests the switch 122. The switch 122 is able to generate a detection signal when it is triggered by the trigger 115 and to transmit the signal of detection at the electronic control board 103.

The electronic control board 103 is able to control the light source 106, the reader 107 and the display screen 108, and to transmit an activation signal to the first connector 114, when it receives the detection signal.

The control module 100 further comprises a first fixing member 123 adapted to cooperate with a second fixing member 223 of the first food distribution module 200 or with a second fixing member 323 of the second food distribution module 300 for interchangeably attaching the first module 200 or the second food delivery module 300 to the control module 100. The first attachment member 123 comprises rails projecting from a flat upper surface 124 of the housing 102 for receiving a housing. food distribution module.

Figures 7 to 9 schematically represent the first food distribution module 200.

The first food distribution module 200 comprises a housing 202 adapted to be fixed to the housing 102 of the control module 100, a tank support 203, a food tank 204 and a second electrical connector 214.

The housing 202 of the first food distribution module 200 comprises a second fixing member 223, adapted to cooperate with the first fixing member 123 to fix the first food distribution module 200 on the control module 100. fastener 223 includes slides in a flat bottom surface 224 of the housing 202. The rails are slidably engageable in the rails to secure the food delivery module 200 to the control module 100.

The first electrical connector 114 and the second electrical connector 214 are arranged to be engaged with each other when the first food distribution module 200 is attached to the control module 100.

More specifically, the rails of the first fastener 123 are slidable in the slideways of the second fastener 223 in a sliding direction, and the second electrical connector 214 is adapted to engage first electrical connector 114 in a direction parallel to the sliding direction.

Once the second electrical connector 214 is in engagement with the first electrical connector 114, the control electronic card 103 of the control module 100 detects the presence of the first food distribution module 200. For this purpose, the first food distribution module 200 comprises a first resistor located on an electronic board 225 having a first value. The control module 100 and the food distribution module 200 form a voltage divider circuit capable of detecting the value of the first resistor when the first food distribution module 200 is attached to the control module 100.

The reservoir 204 is suitable for containing solid food to be dispensed. The reservoir 204 comprises a tube 205 and a stopper 206. The tube 205 has a cylindrical side wall 207 delimiting a cavity 208 for receiving the food, and a bottom wall 209 of conical shape. The cavity 208 may have a volume equal for example to 60 milliliters. The tube 205 has a dispensing orifice 210 formed at the top of the bottom wall 209. The dispensing orifice 210 has a diameter of between 1 and 4 millimeters, for example 2.4 millimeters. The diameter of the dispensing orifice 210 may vary depending on the size of the food grains to be dispensed.

The wall 207 of the tube 205 has graduations 211 for visualizing the amount of food contained in the reservoir 204 at the time of filling the reservoir.

The plug 206 is adapted to be aimed on the tube 205 to close the reservoir 204 after filling.

The reservoir support 203 is adapted to receive the reservoir 204. For this purpose, the reservoir support 203 comprises a tubular body 212 into which the reservoir 204 can be inserted. The body 212 has an opening 213 making it possible to leave the graduations 211 visible. when the reservoir 204 is received in the support 203, which allows an operator to controlling the amount of food remaining in the tank 204. The tank 204 can be easily replaced by another tank.

The tank support 203 is rotatably mounted on the housing 202 through a pivot connection 215. The pivot connection 215 has an axis of rotation substantially perpendicular to the sliding direction of the rails in the rails. The axis of the pivot connection 215 is also substantially perpendicular to the axis of the handle 101 when the first food distribution module 200 is fixed on the control module 100.

The first food distribution module 200 further comprises an actuator 216 and a damping block 217.

In the case of the first food distribution module 200, the actuator 216 comprises a vibrator 218 attached to the tank support 203. The vibrator 218 is electrically connected to the second electrical connector 214 via the electronic module 225. When activated , the vibrator 218 is able to impart to the tank 204 mechanical vibrations causing a flow of food from the inside of the tank 204 to the outside of the tank through the dispensing orifice 210.

The damping block 217 is disposed between the housing 202 of the food distribution module 200 and the tank support 203 and serves to damp the vibration of the vibrator 218.

The pivot connection 215 between the tank support 203 and the housing 202 makes it possible to limit the transmission of the vibrations of the support 203 towards the housing 202.

In the first configuration of the food dispenser, the first food dispensing module 200 is attached to the control module 100 (Fig. 1).

When an operator wishes to deliver solid food into an enclosure 400 containing animals to feed, the operator grasps the handle 101 and approaches the trigger 1 15 of the enclosure 400. As illustrated in Figure 10, the operator comes position the C-shaped end 1 17 of the trigger 1 15 against an annular flange 417 surrounding a opening 418 of the enclosure 400 containing the animals. In this position, the dispensing opening 210 of the reservoir 204 is above the opening of the enclosure. The C-shaped end of the trigger thus allows the operator to correctly position the dispensing opening 210 relative to the opening 418 of the enclosure 400.

The operator uses the weight of the distributor 1 to rotate the trigger 1 15 relative to the housing 102 of the control module 100.

The trigger 1 15 thus passes from the first position in which the trigger 1 15 does not bias the switch 122 to the second position in which the trigger 1 15 solicits the switch 122.

When the trigger 1 15 requests the switch 122, the switch 122 generates a detection signal which is transmitted to the control electronic card 103.

The food dispenser 1 is able to function selectively according to two modes of operation: a first mode of operation (or "manual" operating mode) and a second mode of operation (or "automatic" mode of operation).

According to the first mode of operation, when the electronic control board 103 receives the detection signal, the electronic control board 103 is programmed to perform the following steps:

the control electronic card 103 transmits to the actuator 216 an activation signal via the first connector 1 14 and the second connector 214,

simultaneously, the control electronic card 103 controls the display screen 108 to display a value of quantity of food distributed, and

- Simultaneously, the electronic control board 103 controls the light source 106 so that the light source 106 emits light, as long as the activation signal is transmitted to the actuator.

When the actuator 216 receives the activation signal, the actuator 216 triggers a flow of food through the dispensing orifice 210. More specifically, the activation signal has the effect of activating the vibrator 218 so that the vibrator 218 generates vibrations. The vibrations imparted to the food tank 204 have the effect that food contained in the tank 204 flows through the dispensing orifice 210 to the enclosure 400.

As long as the trigger 115 biases the switch 122, the control electronic board 102 activates the actuator 216 and feed is continuously dispensed at a constant rate. The display screen 108 displays in real time the amount of food distributed. For example, the amount of food dispensed may be displayed as a volume value of food, weight of food, and / or number of fed animals.

When the desired amount of food has been dispensed, the operator ends the distribution. To this end, it moves the trigger 115 away from the enclosure 400, so that the trigger 115 stops requesting the switch 122. The actuator 216 no longer receives an activation signal, the vibrator 218 no longer includes tank 204 vibration and food distribution ceases.

According to the second mode of operation, when the electronic control board 103 receives the detection signal, the electronic control board 103 is programmed to perform the following step:

the control electronic card 103 controls the reader 107 so that the reader 107 reads information identifying the enclosure and / or information relating to the number of animals contained in the enclosure.

The reader 107 may for example be an optical reader, such as a barcode reader for example. In this case, the speaker 400 has a label on which is inscribed the information, in the form of a bar code for example. The information on the enclosure 400 may be representative of a code identifying the enclosure 400 or a number of animals contained in the enclosure 400, this information being adapted to be read by the optical reader 107. Alternatively, the reader 107 may be a radio frequency reader, RFID type. In this case, the speaker 400 has an RFID tag in which the information is recorded. When it receives a radiofrequency excitation signal emitted by the RFID reader 107, the RFID tag is able to generate a response signal representative of a code identifying the enclosure 400 or a number of animals contained in the enclosure 400.

The reader 107 generates a signal representative of the information read and transmits the signal to the control electronic card 103.

The control electronic card 103 is programmed to perform the following steps:

the electronic control card 103 calculates a value of quantity of food to be dispensed as a function of the information read, for example the information relating to the number of animals contained in the enclosure,

the control electronic card 103 transmits to the actuator 216 an activation signal via the first electrical connector 114 and the second electrical connector 214,

simultaneously, the electronic control board 103 controls the light source 106 so that the light source 106 emits light, the light being emitted as long as the activation signal is transmitted to the actuator 216,

when the dispensed food quantity value reaches the previously calculated quantity value, the control electronic card 103 stops transmitting the activation signal for the food distribution to cease.

In a variant, the electronic control card 103 is programmed to perform the following steps: the electronic control card 103 calculates a duration of the activation signal as a function of the information read, for example information relating to the number of animals contained in the enclosure 400,

simultaneously, the electronic control board 103 controls the light source 106 so that the light source 106 emits light, as long as the activation signal is transmitted to the actuator 216,

when the duration of the activation signal reaches the duration of the activation signal calculated previously, the control electronic card

103 stops transmitting the activation signal for the food distribution to stop.

As long as the actuator 216 receives the activation signal, the actuator 216 generates a flow of food through the dispensing orifice. More specifically, the activation signal has the effect of activating the vibrator 218 so that the vibrator 218 generates vibrations. The vibrations imparted to the food tank 204 have the effect that food contained in the tank 204 flows continuously and with a controlled flow through the dispensing orifice 210 to the enclosure 400.

In this second mode of operation (or "automatic" mode of operation), the food distribution stops automatically when an appropriate quantity of food has been dispensed, this quantity being a function of the information read by the reader 107.

However, the flow of food can be interrupted if the operator impromptuely moves the trigger 115 of the enclosure 400 and the trigger 115 stops to solicit the switch 122 being dispensed. During the food distribution, the display screen 108 displays in real time the quantity of food dispensed.

The light source 106 makes it possible to illuminate the surface of the water contained in the enclosure 400 in a grazing manner so that the operator can visualize the food dispensed during dispensing.

The control electronic card 103 may include a memory for recording feeding data as the distribution proceeds. These feeding data may include, for example, an identifier of the enclosure 400 in which the food has been delivered, the date and time of feeding and the quantity of food delivered. This data can be transmitted to an external computer server and archived for health monitoring.

The control electronic card 103 may further detect when an enclosure 400 has already been recently dispensed and inhibit the activation signal to prevent triggering of the distribution. Conversely, the distributor can warn the operator when an enclosure has not received food at the end of the feeding process. In this way, feeding errors can be reduced. In addition, the use of the food dispenser 1 is more flexible since the distribution can be interrupted and then taken over by another operator without risk of error.

Figures 1 1 and 12 schematically show the second food distribution module 300.

The second food delivery module 300 comprises a housing 302, a food dispensing nozzle 303, an actuator 316 and a second electrical connector 314.

Like the first food distribution module 200, the housing 302 of the second food distribution module 300 comprises a second fixing member 323, able to cooperate with the first fixing member 123 for detachably fixing the second dispensing module 300 food on the control module 100. The second fastener 323 includes slides, the rails of the control module 100 being adapted to be engaged by sliding in the slides 123 to fix the second food distribution module 300 on the control module 100.

The first electrical connector 114 and the second electrical connector 314 are arranged to be engaged with each other when the second food distribution module 300 is attached to the control module 100.

More specifically, the rails of the first fastener 123 are slidable in the slideways of the second fastener 323 in a sliding direction, and the second connector 314 is adapted to engage with the first connector 114 in a direction parallel to the direction of sliding.

Once the second electrical connector 314 is in engagement with the first electrical connector 114, the electronic control board 103 of the control module 100 detects the presence of the second food distribution module 300. For this purpose, the second food distribution module 300 includes a second resistor located on an electronic pad 325 and having a second value different from the first value. The voltage divider circuit formed by the control module 100 and the second food distribution module 300 is able to detect the value of the second resistor when the second food distribution module 300 is attached to the control module 100.

A dispensing channel 304 extends inside the dispensing nozzle 303 to a dispensing orifice 310. The dispensing channel may be formed by a pipe extending inside the dispensing nozzle 303. The dispensing nozzle 303 and the hose can be replaced if necessary.

The actuator 316 comprises a valve 318 having a closed position in which the valve 318 prohibits a flow of food in the dispensing channel 304 and an open position in which the valve 318 allows a flow of food in the dispensing channel 304. The valve 318 is electrically connected to the second electrical connector 314, via the electronic card 325. In this way, the opening of the valve 318 can be controlled by the electronic control board 103 of the control module 100 when the second connector 314 is engaged with the first connector 114.

As illustrated in FIG. 14, the distribution channel 304 is able to be connected to an external tank 500 containing liquid food to be dispensed via a connecting tube 319.

Figures 15 and 16 schematically show the food tank 500 clean to be connected to the second food distribution module 300.

The reservoir 500 comprises walls 501 delimiting a cavity adapted to contain liquid food. The cavity may for example contain 8 liters of liquid food.

The reservoir 500 further comprises a compartment 502, adjacent to the cavity, and a pump 503, a battery 504 and a stirrer 505 contained in the compartment 502.

The battery 504 is suitable for supplying the pump 503 and the stirrer 505 with electrical energy.

When activated, the pump 503 is adapted to inject the liquid food from the interior of the tank 500 to the dispensing channel 304 via the connecting tube 319. The pump 503 may include a pressure regulator which has the effect that the pump 503 is triggered automatically when the pressure in the connecting tube 319 is below a predetermined pressure threshold, and stops when the pressure in the connecting tube 319 reaches the pressure threshold.

The stirrer 505 is adapted to mix the liquid food contained within the cavity 501 of the reservoir 500. The stirrer 505 may be a magnetic stirrer, comprising a first magnet rotated by a motor. The first magnet in rotation generates a rotating magnetic field which causes the rotation of a second magnet disposed inside the cavity 501. The stirrer 505 ensures homogenization of the liquid food to maintain a concentration of living organisms homogeneous.

The tank 500 may further have rollers 506 to facilitate movement of the tank 500 between the racks.

In the second configuration of the food dispenser 1, the second food dispensing module 300 is attached to the control module 100 (Fig. 2).

When an operator wishes to deliver food into an enclosure 400 containing animals, he grasps the handle 101 of the control module 100 and approaches the trigger 115 of the enclosure 400 containing animals to feed. As illustrated in FIG. 13, the operator bears the C-shaped end 117 of the trigger 115 on an annular flange 417 surrounding an opening 418 of the enclosure 400 containing the animals. In this position, the dispensing orifice 310 of the nozzle 303 is located above the opening 418 of the enclosure 400. The C-shaped end 117 of the trigger 115 thus allows the operator to position correctly the dispensing orifice 310 relative to the enclosure 400.

As in the first configuration, the operator uses the weight of the distributor 1 to rotate the trigger 115 relative to the housing 102 of the control module 100.

The trigger 115 moves from the first position in which the trigger does not solicit the switch 122 to the second position in which the trigger 115 requests the switch 122.

When the trigger 115 requests the switch 122, the switch 122 generates a detection signal which is transmitted to the control electronic card 103.

The food dispenser 1 is able to operate according to the two operating modes previously described: a first operating mode (or "manual" operating mode) and a second operating mode (or "automatic" operating mode).

According to the first mode of operation, when it receives the detection signal, the control electronic card 103 is programmed to perform the following steps: the control electronic card 103 transmits to the actuator 316 an activation signal via the first connector 114 and the second connector 314,

the control electronic card 103 controls the display screen 108 to display a value of quantity of food distributed, and

the control electronic board 103 controls the light source 106 so that the light source 106 emits light, as long as the activation signal is transmitted to the actuator 316.

When the actuator 316 receives the activation signal, the actuator

316 triggers a flow of food through the dispensing orifice 310. More specifically, the activation signal has the effect of moving the valve 318 from the closed position to the open position. Once the valve 318 in the open position, food contained in the tank 500 is injected by the pump 503 via the connecting tube 319 and the distribution channel 304 to the dispensing orifice 310. This has the effect that the food contained in the tank 500 flows through the connecting tube 319, the distribution channel 304, and through the dispensing orifice 310 to the enclosure 400.

As long as the trigger 115 biases the switch 322, the control electronic card 103 activates the actuator 316 and food is dispensed. The display screen 108 displays in real time the amount of food distributed. The amount of food value can be displayed in the form of a volume value of food, weight of food and / or number of fed animals.

When the desired amount of food has been dispensed, the operator moves the trigger 115 away from the enclosure 400, so that the trigger 115 stops urging the switch 122. In the absence of an activation signal, the valve 318 moves from the open position to the closed position and the food distribution stops.

According to the second operating mode ("automatic" operating mode), when it receives the detection signal, the electronic control board 103 is programmed to execute the following step:

the control electronic card 103 controls the reader 107 for the reader 107 to read information identifying the speaker 400 and / or information relating to the number of animals contained in the chamber.

The optical reader 107 generates a signal representative of the information read and transmits the signal to the control electronic card 103.

The control electronic card 103 is programmed to perform the following steps:

the electronic control card 103 calculates a value of quantity of food to be dispensed according to the information read, for example information relating to the number of animals contained in the enclosure 400,

the control electronic card 103 transmits to the actuator

316 an activation signal via the first connector 114 and the second connector 314,

simultaneously, the electronic control board 103 controls the light source 106 so that the light source 106 emits light, as long as the activation signal is transmitted to the actuator 316,

when the dispensed food quantity value reaches the previously calculated quantity value, the control electronic card 103 stops transmitting the activation signal so that the valve 318 moves from the open position to the closed position and the dispensing food stops.

Alternatively, the control electronic card 103 is programmed to perform the following steps: the electronic control card 103 calculates a duration of the activation signal as a function of the information read, for example information relating to the number of animals contained in the enclosure 400,

the control electronic card 103 transmits to the actuator 316 an activation signal via the first connector 114 and the second connector 314,

simultaneously, the electronic control board 103 controls the light source 106 so that the light source 106 emits light, as long as the activation signal is transmitted to the actuator 36,

when the duration of the activation signal reaches the duration of the activation signal calculated previously, the electronic control board 103 stops transmitting the activation signal so that the distribution of food ceases.

As long as the actuator 316 receives the activation signal, the actuator 316 generates a flow of food through the dispensing orifice 310. More specifically, the activation signal has the effect of keeping the valve 318 in the open position. so that food contained in the tank 500 flows continuously and with controlled flow through the dispensing orifice 310 to the enclosure 400.

In this second mode of operation, the food distribution stops automatically when an appropriate amount of food has been dispensed, which is a function of the information read by the reader.

However, the flow of food may be interrupted if the operator impromptuously moves the trigger 105 away from the enclosure 400 and the trigger 115 stops urging the switch 122 being dispensed.

The display screen 108 displays in real time the quantity of food distributed. In the embodiment which has just been described with reference to FIGS. 1 to 16, the food dispenser 1 comprises a control module 100 (or main module) and at least one food distribution module 200 or 300, separated from the control module 100. The food distribution module 200 or 300 can be removably attached to the control module 100. In particular, in this embodiment, the dispensing module 200 or 300 comprises a housing 202 or 302, separate from the housing 102 of the control module 100, and can be fixed thereto by means of fasteners 123 and 223 or 323.

However, in another embodiment, the food dispenser 1 may comprise a control unit 100 and a food distribution module 200 (or 300) inseparable. In particular, the two modules may comprise a common box (instead of two separate boxes).

In the case where the food dispenser 1 is a solid food dispenser, the food dispenser 1 comprises a housing which contains the electronic control board 103, the battery (s) 104, the detection member 105, the light source 106, the reader 107 and the display screen 108, and on which is fixed the tank support 203 for receiving the reservoir for the food 204.
