Description

The useful model belongs to the field of keeping pets. The automatic feeder for pets with a clock mechanism is designed to automatically provide pets (cats, dogs, etc.) with dry food according to a specified schedule, and allows solving the problem of portioned feeding during the absence of the owner of the pet for some time.

Currently, there are automatic feeders that perform the function of automatically dispensing feed at the time specified by the user. For example, Mo patents CM2673085U, I52005066905(A1),

ОШ5О560834(82), И57650855(82), however, they contain electronic components: microcontrollers, display, electric motors or servo drives, which makes such devices expensive and energy-intensive. The closest in terms of functionality to this useful model is the automatic feeder for pets according to Mo UORbBZ-302258 and 54981106 patents, which has a cylindrical container with food compartments located in a body with a hole, each of which has a door. Also in the body of the feeder is a clock mechanism with a disc and removable pins located on it. The clock mechanism transmits torque to the feed container by engaging the pins of the disc with the feet of the container. When the door of one of the feed compartments aligns with the hole in the body, it opens and a portion of the feed is poured out of the compartment. At the same time, it is possible to pre-program the activation of the feeder one or more times during the day at certain moments of time by setting the pins on the disc of the clock mechanism in the required position.

The disadvantage of such a device is the large force of friction between the moving parts (the container with feed and the body), which requires considerable effort to activate the device, which means a high torque for the clock mechanism used in it. At the same time, the force of friction between the parts of the device will be greater, the more the feeder is loaded with dry feed, because the doors of the feed-filled compartments create a large pressure on the bottom of the body of such a feeder. Especially for large pets, such as cats or dogs, the food has a significant weight, so it puts a lot of pressure on the parts of the device. However, the battery-operated clock movements in common use do not have enough power to power such a device. In addition, another disadvantage is the need to use a watch

From a mechanism with a 24-hour cycle. All this makes the manufacture of such a device problematic due to the need to use a specific clock mechanism with a 24-hour cycle and a very high torque, and such clock mechanisms are not widely used and require separate development and manufacture.

The useful model is based on the task of improving an automatic feeder with a clock mechanism in such a way as to minimize the frictional forces between the parts moving relative to each other. This will make it possible to use as a driving mechanism a conventional clock mechanism of the electromechanical type, which works on a battery and has a low torque.

The task is solved by the fact that in the feeder, which contains a housing with a lid, which has an opening for dispensing portions of feed, an electromechanical clock mechanism that operates on a battery, a container that has one of the following shapes: a cylinder, a regular prism, a truncated cone or a truncated regular pyramid located on an axis with the possibility of rotation and having feet along the perimeter, inside which there are compartments located along the perimeter, each of which has a door at the bottom, a disc with removable wings attached to the perimeter, which is located on an axis with the possibility of rotation and is intended for torque transmission from the clock mechanism to the container due to the engagement of the wings of the disk with the feet of the container, according to the useful model, each compartment of the container except for the door has a movable locking element, which is designed to lock or unlock the door of the compartment and has the ability to change its state (unlocked / closed) when interacting with other parts of the device.

At the same time, the disk is connected to the clock mechanism thanks to a system of gears or a worm gear with a gear ratio that is selected in such a way that the disk makes exactly 1 revolution in 24 hours.

At the same time, there is a platform under the container, which is parallel to the lower plane of the container and has a cut-out sufficient for the door of one of the container compartments, which is above the cut-out, to open, there is a gap between the container and the platform, and as a locking element of each compartment of the container, a locking lever is used, the movable end of which is in contact with the platform, and the plane of rotation of which is perpendicular to the lower plane of the container. because A latch lever is used as a locking element of each compartment of the container,

the plane of rotation of which is parallel to the lower plane of the container.

At the same time, the door of each compartment of the container has a lever for closing, which allows you to close the door when this lever interacts with other elements of the device.

At the same time, the doors of each compartment of the container have at least one spring, which allows them to open under the weight of the feed when the corresponding locking element is opened, but to close automatically under the action of the spring after the compartment is released from the feed.

The essence of the useful model is explained by the drawings, which show: in Fig. 1 - a general view of one of the variants of the implementation of the feeder, in particular according to paragraphs 2, From the formula of the useful model (for better clarity, some design elements are shown translucent); in Fig. 2 - different versions of the container: Fig. 2a - in the form of a cylinder, Fig. 26 - in the form of a regular prism,

Fig. 2c - in the form of a truncated cone, Fig. 2d - in the form of a truncated regular pyramid; in Fig. C - variant of the implementation of locking elements in the form of a locking lever; in Fig. 4 - a variant of the implementation of locking elements in the form of a latch lever; in Fig. 5 - the doors of the container compartments, which have a lever for closing; in Fig. b - the doors of the container compartments, which have a spring for closing.

Automatic feeder for pets with a clock mechanism has a case (1) with a cover (11), which has an opening (12) for dispensing portions of feed, inside the case are the device details: a clock mechanism (2) of the electromechanical type, powered by a battery; container (3) in the form of a cylinder (Fig. 2a), or a regular prism (Fig. 2b), or a truncated cone (Fig. 2c), or a truncated regular pyramid (Fig. 2c), which is located on an axis with the possibility of rotation and has legs (31) along the perimeter, compartments (32) are located inside the container along its perimeter, each of which has a door (33) at the bottom; disk (4), on the perimeter of which removable wings (41) are fixed, which is located on an axis with the possibility of rotation and is designed to transmit torque from the clock mechanism to the container due to the engagement of the wings of the disk with the legs of the container; and differs in that each compartment of the container, except for the door, has a movable locking element (34), which is designed to lock or unlock the door of the compartment and has the ability to change its state (unlocked/closed) when interacting with other parts of the device.

The driving leash of the device is a clock mechanism (2) of the electromechanical type, which

Zo works on a battery. The torque from the clock mechanism is transmitted to the disc (4) with removable wings (41) fixed around its perimeter. At the same time, the disk can be fixed both directly on the axis of the clock mechanism (in this case, a clock mechanism with a 24-hour cycle is used), and on an axis separate from the clock mechanism (in this case, the torque from the clock mechanism is transmitted to the disk thanks to a system of gears or worm gear (21) with a gear ratio that is selected so that the disc makes exactly 1 revolution in 24 hours, so this allows the use of a clock mechanism with a 12-hour cycle). Removable wings (41) are fixed around the perimeter of the disc. The location of the wings in different places on the perimeter of the disk will determine the time in a 24-hour interval at which the feeder will dispense portions of feed. The number of wings attached to the disc will determine the number of feedings during the day. The disc with the vanes attached to it transmits the torque from the clockwork to the container by engaging the disc wings with the container feet, which rotates the container on its axis. A feed container is a container that has one of the following shapes: cylinder, regular prism, truncated cone, truncated regular pyramid.

Inside the container along the perimeter are compartments (32) with doors (33) in their lower plane. At the same time, the inner and/or outer wall of each compartment relative to the central axis of the container should be made at an angle (as shown in Fig. 2), so that the compartments have a larger area in the horizontal cross-section from above than from below.

This will reduce the load from the feed on the doors and locking elements of the compartments, and will also make the process of loading the feeder with portions of feed more convenient, since the compartments will have a larger volume. Separate portions of dry feed are loaded by the user in advance into the container compartments, and are issued automatically according to the specified schedule. The number of compartments in the container may be sufficient to automatically feed the animal without human intervention from one to several times a day for several days. For example, a feeder with a container that has 12 compartments will allow feeding an animal without human intervention 2 times a day for 6 days, or 3 times a day for 4 days, etc. At any time, the user can add food to the empty feeder compartments. A distinctive feature of the useful model is the movable locking elements (34), designed to lock the doors of each compartment of the container and unlock the doors to open them at the right time. This design allows the food through the door of the compartment not to create strong pressure on other parts of the device relative to which the container with food moves. Thanks to this, the friction between the moving parts of the device is significantly reduced. Locking elements can have the form of a locking lever (Fig. 3), which opens in the direction opposite to the opening of the door of the compartment, and the plane of rotation of such locking levers is perpendicular to the lower plane of the container. Or they can take the form of a latch lever (Fig. 4), the plane of rotation of which is parallel to the lower plane of the container. To open the door of the feed compartment at the right time, the locking element of the corresponding compartment must open. A different mechanism can be used for this. For example, in one version of the device, there may be a platform with a cutout (5) located under the feed container at a short distance from the bottom plane of the container. Then the locking elements in the form of a locking lever contact the platform with a movable end. When the container rotates around its axis, the locking lever aligns with the cutout in the platform and opens, unlocking the compartment door, which in turn opens under the weight of the feed. A portion of feed comes out of the container compartment and is directed to the outlet of the feeder, falling into the food bowl (7), which is located next to the feeder near the outlet. To prevent the food bowl from moving relative to the feeder outlet, the bowl can be attached to the feeder. A hopper (6) fixed inside the feeder housing can be used to direct feed to the outlet. The door of the compartment, after the portion of feed has left it, is closed either thanks to the lever (35), which is attached to the door and contacts other elements of the device during further rotation of the container, or thanks to the spring (36), which can be present in the design of the door of the compartment. The locking lever, in contact with the platform, closes and blocks the door of the compartment during further rotation of the container. Another variant of the construction is a device in which there is no platform under the container. In this case, the locking elements can be made in the form of a latch lever that opens and closes upon contact with other structural elements of the device during container rotation, and the plane of rotation of the latch lever is parallel to the bottom plane of the container. And the doors of the compartment, after they are opened and a portion of feed is dispensed, are closed either thanks to the spring installed in them (36), or during the further rotation of the container when interacting with other parts of the device structure directly or through a lever (35) attached to the door. All the details of the device are compact

They are located in the body of the feeder. For example, the clock mechanism can be placed under the container, the disk - in a vertical position next to the container, so the feeder has compact dimensions. In order to prevent a situation where, in the absence of the owner, the battery of the watch mechanism will discharge and the feeder will stop working, the device can be equipped with an electronic or arrow indicator of the battery charge level. This will allow you to check the battery charge in advance before leaving your pet for a while, and if necessary, replace it. Such a check of the battery charge level can be done every time the feeder is loaded with new portions of feed. An electronic battery status indicator can also be used, which checks the charge level constantly or with a certain frequency, and signals the need to replace the battery by lighting up or flashing the LED.
