Description

[Technical Field]

[0001] The present invention relates to a toy dispenser for companion animals, and more particularly to a toy dispenser that can selectively dispense toys by appropriately controlling the rotation angle and direction of a motor. [Background technology]

[0002] Generally, companion animals such as dogs and cats experience stress symptoms such as separation anxiety when their owners are away from home, and in severe cases, they may damage household items or furniture or exhibit bowel problems. Therefore, there is a need for a method to attract the attention of companion animals and appropriately relieve stress while their owners are away, and as a result, there has been growing interest recently in devices that automatically provide food and toys periodically. For example, Patent Document 1 introduces a device that automatically supplies nosework balls for companion dogs at set times. However, the ball supplying device of Patent Document 1 has the following problems. First, a caterpillar conveyor is used to transport a plurality of loaded nose work balls one by one to the discharge port, but the caterpillar conveyor occupies a very large area, which limits the miniaturization of the device. Second, conventional devices have the limitation of not being able to determine the size of the pet and the size of the ball, and therefore are unable to provide a nose work ball of an appropriate size that fits the size of the pet. In addition, companion animals can become stressed and overly sensitive when exposed to new sounds, and socialization education to alleviate this is necessary. For example, it could be the sound of an elevator in an apartment hallway, or the sound of footsteps in the hallway. However, conventional ball dispensers only dispense nose work balls and are unable to perform the function of socializing companion animals. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Korean Patent No. 10-2354771 (Announced 2022.01.21) Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been devised in light of the above background, and its object is to provide a play equipment dispenser that can quickly and effectively dispense equipment while minimizing the size and reducing the installation area. Another object of the present invention is to provide a device that can determine the size of a companion animal and / or the size of a toy and provide a toy of an appropriate size that fits the size of the companion animal. A further object of the present invention is to provide a device that performs the socialization function of companion animals. [Means for solving the problem]

[0005] To achieve this object, one aspect of the present invention provides a companion animal toy supplying device, including: a housing having an outlet; a storage container installed inside the housing and having at least one outlet hole formed between its center and edge; a propeller having at least one pocket for storing items and rotating to move items stored in the at least one pocket toward the side where the outlet hole is formed; a door for opening and closing the outlet hole of the storage container; an outlet guide for guiding items that have been seated in the pocket and then discharged through the outlet hole of the storage container to move to the outlet of the housing; a drive unit for rotating the propeller; and a control unit for controlling the operation of the drive unit. In one aspect of the present invention, in a companion animal plaything supply device, the propeller is configured to rotate inside the storage container and includes a central block and a plurality of support posts extending radially from the central block, and the pockets can be formed between adjacent support posts. In one aspect of the present invention, the door of the pet plaything supply device may be rotatably coupled to the center of the container, and the container may be provided with a stopper for limiting the range of rotation of the door.

In addition, in the companion animal toy supplying device according to one aspect of the present invention, the external stimulating sound may be generated by playing a sound file received and stored by the user. [Effects of the Invention]

[0006] According to the present invention, since the playthings can be transported to the discharge hole by a propeller system, the device can be made compact and the installation area can be reduced. In addition, by linking the propeller and the door together, the number of motors used can be reduced, which in turn makes it possible to make the device smaller and reduce power consumption. Furthermore, since the size of the companion animal and the size of the toy can be grasped, toys of an appropriate size that fits the size of the companion animal can be provided. Furthermore, when a toy is dispensed, a preset sound signal is sent to the speaker so that the corresponding sound is emitted to the outside, thereby carrying out socialization education that reduces negative reactions to external noises that cause negative reactions, such as elevator sounds and footsteps in the hallway. In particular, the type of sound to be emitted can be directly specified by the user in consideration of the characteristics of each companion animal, thereby enabling personalization of the companion animal.

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In this specification, when a component is connected or coupled to another component, this includes not only the case where the component is directly connected or coupled to the other component, but also the case where the component is indirectly connected or coupled through an intermediate element. Furthermore, when a component is directly connected or coupled to another component, it does not mean that there is an intermediate element. Furthermore, unless otherwise specified, when a part includes or comprises a certain element, it does not mean that the other element is excluded, but that the part may further include or comprise the other element. Furthermore, although some parts in the drawings attached to this specification are exaggerated and different from the actual size, this is for the convenience of explanation and understanding only, and it should not be construed as limiting or distorting the scope of the present invention. <First Example> As shown in the front perspective view of FIG. 1a and the rear perspective view of FIG. 1b, the toy supply device 100 according to the first embodiment of the present invention includes a housing 110 enclosing an internal space, a cover 120 coupled to the top of the housing 110, and an outlet 116 formed at the bottom end of one side of the housing 110. Although the housing 110 is shown in the drawings as having a conical shape, it is not limited to this and may have various shapes such as a truncated cone, a prism, a truncated pyramid, or a hemisphere. The cover 120 may include a circular housing coupling part 121 detachably coupled to the upper end of the housing 110, a transparent cover 122 coupled to the upper part of the housing coupling part 121, and an upper end cover 123 detachably coupled to the upper end of the transparent cover 122. Referring to Figures 2 and 3, which show the state in which the cover 120 is separated from the housing 110, inside the cover 120 are installed a storage container 130 capable of storing a plurality of toys, a propeller 140 installed to rotate inside the storage container 130, and a door 150 for opening and closing a discharge hole 138 formed at the bottom of the storage container 130. 4 and 5, a horizontal partition wall 114 is formed inside the housing 110, and the receiving container 130 is installed on the upper surface of the horizontal partition wall 114. As shown in FIG. The horizontal partition 114 has a through hole 115 formed therein, which is connected to the discharge hole 138 of the receiving container 130 , and a motor mounting part 170 , a speaker 174 , an LED 176 , etc. may be installed at the bottom of the horizontal partition 114 . A motor (not shown in the drawings) for rotating the propeller 140 is installed in the motor mounting portion 170 . A rotating shaft 172 is installed at the center of the horizontal bulkhead 114 and the storage container 130, and the upper end of the rotating shaft 172 is fixedly connected to the center of the propeller 140. The lower end of the rotating shaft 172 may be directly connected to the motor shaft or indirectly connected to the motor shaft using a gear, pulley, wire, belt, chain, etc. The motor mounting unit 170, which includes the motor and a gear connected to the motor shaft to transmit power, may correspond to a driving unit that rotates the propeller under the control of the control unit 200, which will be described later. Also, inside the housing 110, a discharge guide 180 is installed to guide the items that pass through the discharge hole 138 of the receiving container 130 and the through-hole 115 of the horizontal partition wall 114 and fall to the discharge port 116. The bottom of the discharge guide 180 is preferably formed with a smooth curved surface so that the items can move without getting caught. The specific specifications of the discharge guide 180, such as the height and curvature, can be appropriately selected in consideration of the size, weight, discharge speed, and discharge distance of the items to be discharged. A discharge detection sensor 178 for detecting whether or not an article has passed through may be installed on the bottom or side wall of the discharge guide 180. The discharge detection sensor 178 is preferably installed in a position close to the discharge opening 116. The type of the discharge sensor 178 is not particularly limited. For example, an optical sensor consisting of a pair of a light receiving part and a light emitting part, an infrared sensor, a laser sensor, or the like may be used, or a proximity sensor that detects changes in electromagnetic characteristics such as capacitance, resistance, or magnetic field to determine contact or proximity of an object may be used. In addition, a power supply unit 118 and a function button 119 may be installed at the bottom of the housing 110. The power supply unit 118 may include power components such as a power socket and an AC / DC converter for connecting to an external power source, and may also include a rechargeable or non-rechargeable battery. The function buttons 119 may include at least one of a power button, an operation mode selection button, an LED on / off button, and a speaker on / off button. In addition, an animal detection sensor 190 for detecting the approach and size of a companion animal may be installed in the housing 110. A plurality of animal detection sensors 190 may be installed around the housing 110, or a plurality of animal detection sensors 190 may be installed along the height direction of the housing 110. The type of animal detection sensor 190 is not particularly limited, and various types of sensors may be selectively used, or two or more types of sensors may be used in combination, just like the discharge detection sensor 178. In addition, the animal detection sensor 190 may be a ToF type sensor that detects the distance to an object using the time of flight of infrared rays, lasers, etc. If multiple animal detection sensors 190 are installed on the outer surface of the housing 110, for example, if an animal is detected by one sensor, it can be determined to be a small animal, and if an animal is detected by two or more sensors, it can be determined to be a large animal. The receiving container 130, the propeller 140, and the door 150 will be described in detail below. The storage container 130 is for storing a plurality of toys, and as shown in the perspective view of FIG. 6 and the cross-sectional view of FIG. 7, includes a circular bottom 131, side walls 132 formed at a predetermined height on the edge of the bottom 131, and guide slits 133 formed at a predetermined angle along the inner surface of the side walls 132. The bottom 131 and the sidewall 132 may be manufactured separately and then detachably joined together, or may be manufactured as a single unit. At least one item detection sensor 192 may be installed inside the side wall 132. The item detection sensor 192 is for detecting the number and size of items stored in the storage container 130, and the type thereof is not particularly limited. The item detection sensor 192 may selectively use various types of sensors, or may use two or more types of sensors in combination, just like the discharge detection sensor 178. Also, the item detection sensor 192 may use a ToF type sensor that detects the distance to an object using the time of flight of infrared rays, lasers, etc. It is desirable that the bottom 131 be formed with a slope that decreases in height from the center toward the side wall 132. This has the advantage that the stored items can be detected more accurately using the item detection sensor 192 as they move toward the side wall 132. A circular pipe 137 is formed at the center of the bottom 131, and the upper and lower ends of the circular pipe 137 may protrude from the top and bottom of the bottom 131 by a predetermined height. A rotating shaft 172 is inserted into the through-hole 136 of the circular pipe 137. However, it is preferable that the receiving container 130 is installed so as not to be rotated by the rotating shaft 172. The bottom 131 has a discharge hole 138 formed between the circular pipe 137 and the side wall 132 for discharging items downward. The propeller 140 is installed inside the container 130 and serves to move a plurality of items to the discharge hole 138 sequentially or selectively. Referring to the perspective view of FIG. 8 and the bottom perspective view of FIG. 9, the propeller 140 includes a central block 141 having a shaft coupling hole 142 to which a rotating shaft 172 is coupled, and a plurality of support pillars 145 arranged radially with one end coupled to the central block 141, and the space formed between two adjacent support pillars 145 is used as a pocket for storing items. Therefore, when the propeller 140 is rotated with items stored in the pockets, the stored items are pushed by the support posts 145 surrounding the corresponding pockets and move in the direction of rotation. Since the support pillars 145 have the role of pushing and moving the stored items, they must be manufactured with an appropriate height and thickness, taking into consideration the type, size, and weight of the items. If the height of the support pillars 145 is too low, the items pushed by the support pillars 145 may move to other pockets. In the present embodiment, five support columns 145 are installed on the propeller 140, forming first to fifth pockets (S1, S2, S3, S4, S5) inside the propeller 140. However, the number of support columns 145 and pockets is not limited to this, and any other number can be manufactured. In other words, the number and spacing of the support columns 145 should be determined taking into consideration the size of the products to be stored and the size of the discharge hole 138. The central block 141 may have locking grooves 143 formed on its side, into which the locking protrusions 165 of the locking members 160 attached to the door 150 are inserted. The central block 141 may have one locking groove 143 formed at each position corresponding to the center of each pocket (S1, S2, S3, S4, S5). On the other hand, in the embodiment of the present invention, the ends of the radially arranged support columns 145 are connected to each other using pocket frame members 147. The pocket frame member 147 connects the ends of two adjacent support columns 145 to each other and serves to surround the inner pocket. It is desirable that the pocket frame member 147 has a curvature similar to that of the discharge hole 138 through which the goods are discharged. In this way, when the propeller 140 is rotated at the discharge angle, the goods to be discharged can be accurately positioned above the discharge hole 138, thereby greatly reducing the possibility of malfunction. On the other hand, if adjacent support columns 145 are connected using pocket frame members 147 having a curvature similar to that of the discharge holes 138, empty spaces are generated outside each pocket, and debris may accumulate in these areas. To prevent this, it is desirable to install frame covers 149 between adjacent pocket frame members 147 to eliminate spaces where dirt may accumulate. However, the pocket frame member 147 and frame cover 149 may be omitted if necessary. The door 150 is installed inside the receiving container 130 and serves to open and close the discharge hole 138 . Referring to the perspective view of FIG. 10 and the side view of FIG. 11, the door 150 includes a roughly fan-shaped plate 151, a ring-shaped connecting member 154 formed on one side of the plate 151, a side wall 152 formed on the other side of the plate 151, and a lateral protrusion 153 protruding outward from the upper end of the side wall 152. The coupling member 154 has a circular through-hole 155 into which the circular pipe 137 of the receiving container 130 is inserted. Therefore, the door 150 can rotate around the circular pipe 137. The plate 151 may have a slope that decreases in height toward the sidewall 152, similar to the bottom 131 of the receiving container . An inwardly cutout 159 may be formed on one side edge of the plate 151. By forming the cutout 159 in this manner, even when the door 150 covers the discharge hole 138 as shown in FIG. If a portion of the discharge hole 138 is open in this manner, the debris and dirt that has fallen inside the container 130 can be pushed by the support pillar 145 and discharged to the outside through the discharge hole 138 as the propeller 140 rotates clockwise. A lateral protrusion 153 formed on the edge of the plate 151 is inserted into a guide slit 133 formed in a side wall 132 of the receiving container 130, and the rotation range of the door 150 is limited by a first stopper 134 and a second stopper 135 formed at both ends of the guide slit 133. The first and second stoppers 134 and 135 may be the side wall 132 formed at both ends of the guide slit 133, respectively, or may be separately formed locking structures. For example, as shown in FIG. 12, when the door 150 rotates clockwise and stops at the second stopper 135 of the guide slit 133, the plate 151 of the door 150 covers the discharge hole 138. On the other hand, as shown in FIG. 13, when the door 150 rotates counterclockwise and stops at the first stopper 134 of the guide slit 133, the discharge hole 138 is opened. The side walls 152 and the side projections 153 of the door 150 may be omitted if necessary. In this case, the edge of the plate 151 may be inserted directly into the guide slit 133. Meanwhile, the door 150 and the propeller 140 can be operated independently using separate motors, but in the first embodiment of the present invention, the door 150 is operated in a non-powered manner in conjunction with the propeller 140. Specifically, the door 150 is operated using a locking member 160 selectively coupled to the propeller 140. For this purpose, a locking member coupling part 156 is formed on the door 150. Referring to Figure 14, the locking member coupling part 156 includes a U-shaped side wall 1561 that protrudes from the top of the plate 151 and is open toward the rotation center, a top plate 1562 whose edge is coupled to the top end of the side wall 1561, a cutout 1563 that is cut inward from the edge of the top plate 1562 near the rotation center, an insertion space 1565 formed in the bottom of the top plate 1562, and at least one coupling post 1567 whose bottom end is coupled to the top plate 1562, protrudes upward, and whose side protrudes toward the rotation center from the cutout inner edge of the top plate 1562. In addition, a fixing hole 1568 into which a fixing protrusion 168 formed at the lower end of the locking member 160 is inserted may be formed in the front of the plate 151 on the rotation center side of the locking member coupling part 156. As shown in FIG. 15, the locking member 160 includes a base 161, an elastic member 163 protruding from the top of the base, a locking protrusion 165 protruding from one side of the elastic member 163, and a coupling groove 167 formed on the other side of the elastic member 163. The base 161 preferably has a thickness that allows it to be inserted into the insertion space 1565 of the locking member coupling portion 156 . The elastic member 163 contracts and recovers in a direction perpendicular to the direction of rotation of the door 150, and in this embodiment of the present invention, an elliptical cylindrical elastic member 163 having a predetermined height and thickness is used. The material of the elastic member 163 is not limited, and materials such as polyurethane, rubber, synthetic resin, and metal can be used without limitation as long as they can exert the required elastic force. The locking protrusion 165 is inserted into the locking groove 143 of the propeller 140, and repeats the action of being inserted into or removed from the locking groove 143 depending on the rotation angle of the propeller 140. The coupling groove 167 is formed in the height direction on the side of the elastic member 163, and a portion of the coupling post 1567 of the locking member coupling part 156 is inserted into the coupling groove 167. When the coupling post 1567 is inserted into the coupling groove 167, the elastic member 163 can be prevented from swinging in the rotation direction of the propeller 140. A fixing protrusion 168 is formed on the bottom surface of the base 161 so as to protrude therefrom. When the fixing protrusion 168 is inserted into a fixing hole 1568 of the plate 151 of the door 150, the locking member 160 is fixed to the door 150. FIG. 16 is a diagram showing the state in which the locking protrusion 165 of the locking member 160 is inserted into the locking groove 143 formed in the center block 141 of the propeller 140, and FIG. 17 is a diagram showing that the opposing inner surfaces 143a and 143b of the locking groove 143 and both sides 165a and 165b of the locking protrusion 165 have corresponding shapes. As shown in the drawings, when the center block 141 of the propeller 140 rotates clockwise, the downstream inner surface 143a of the locking groove 143 is formed at an angle close to perpendicular to the tangent direction of the center block 141, and the upstream inner surface 143b of the locking groove 143 is formed at a much smaller angle to the tangent direction than the downstream inner surface 143a. For example, the upstream inner surface 143b of the locking groove 143 may be formed at an angle of about 30 to 60 degrees to the tangent direction. In addition, the downstream side surface 165a of the locking protrusion 165 of the locking member 160 can be formed at an angle equal to the downstream inner surface 143a of the locking groove 143, and the upstream side surface 165b of the locking protrusion 165 of the locking member 160 can be formed at an angle equal to the upstream inner surface 143b of the locking groove 143. On the other hand, if the locking protrusion 165 of the locking member 160 is inserted into the locking groove 143 of the propeller 140 and the door 150 is not caught by either of the stoppers 134, 135, the door 150 can rotate in the same direction as the propeller 140 regardless of which way the propeller 140 rotates. However, after the rotating door 150 engages with the stoppers 134 and 135, the door 150 cannot rotate further in the clockwise direction, but the propeller 140 can continue to rotate in the clockwise direction due to the engagement groove 143 and the gently inclined surface of the engagement protrusion 165. For example, as illustrated in FIG. 18, if the propeller 140 continues to rotate clockwise while the door 150 is caught by the second stopper 135 and cannot rotate further clockwise, the door 150 will be stopped by the second stopper 135, but the upstream inner wall 143b of the locking groove 143 of the propeller 140 will apply pressure to the inclined upstream side surface 165b of the locking protrusion 165 at which the door 150 is stopped. As a result, the elastic member 163 of the locking member 160 gradually contracts toward the opposite side of the rotation center, and eventually the locking protrusion 165 comes out of the locking groove 143 of the propeller 140 (see FIG. 18(a)). If the propeller 140 continues to rotate in this state, the locking protrusion 165 will maintain contact with the side surface of the center block 141 of the propeller 140 due to the restoring force of the elastic member 163 (see FIG. 18(b)). Then, when the propeller 140 rotates further and reaches the next locking groove 143, the locking protrusion 165 is inserted into the locking groove 143 by the restoring force of the elastic member 163 (see FIG. 18(c)). As the propeller 140 continues to rotate, the above process is repeated. On the other hand, if the propeller 140 rotates counterclockwise while the door 150 is caught by the second stopper 135 and cannot rotate clockwise, the inner wall 143a of the locking groove 143 applies pressure to the side surface 165a of the locking protrusion 165, as illustrated in FIG. 19, causing both the propeller 140 and the door 150 to rotate counterclockwise. However, if the door 150 hits the first stopper 134 of the guide slit 133 while the propeller 140 and the door 150 are both rotating counterclockwise, not only the door 150 but also the propeller 140 cannot rotate any further. This is because the inner surface 143a of the locking groove 143, which receives pressure in the rotation direction, and the side surface 165a of the locking protrusion 165, which receives pressure, are both nearly perpendicular to the rotation direction, so the locking protrusion 165 cannot come out of the locking groove 143. Therefore, when rotating the propeller 140 counterclockwise, it is desirable to stop the propeller 140 just before the door 150 engages with the first stopper 134 to prevent damage to the motor and related components. Hereinafter, the operation of the plaything supplying device 100 according to the first embodiment of the present invention will be described with reference to FIG. First, for ease of explanation, it is assumed that the propeller 140 has five pockets, each containing one nosework ball. It is also assumed that at the beginning of operation, the door 150 is in a position that hides the discharge hole 138 and cannot rotate further clockwise due to the second stopper 135, and the locking protrusion 165 of the locking member 160 is inserted into the locking groove 143 of the propeller 140. In this state, if a command to eject ball No. 1 is generated or received, the device's control unit (200 in FIG. 24) controls the motor 220 to rotate the propeller 140 clockwise (forward). In this case, as shown in FIG. 18, the door 150 cannot rotate any further and the propeller 140 continues to rotate, so the locking protrusion 165 may be removed from the locking groove 143 and then inserted into the next locking groove 143, and this process may be repeated (see FIG. 20(a)). Next, the control unit 200 stops the propeller 140 after the first pocket containing the first ball passes through the discharge hole 138 and before the adjacent second pocket passes through the discharge hole 138. Preferably, the propeller 140 is stopped at a position where the center line of the second pocket (a virtual line connecting the rotation center of the propeller 140 and the center of the pocket frame member 147 of the second pocket) and the center line of the discharge hole 138 (a virtual line connecting the rotation center of the propeller 140 and the center of the discharge hole) coincide with each other. Meanwhile, it is preferable that the locking protrusion 165 of the door 150 is inserted into the locking groove 143 of the propeller 140 again at the position where the propeller 140 stops, but this is not necessarily limited to this. (See (b) of FIG. 20) Subsequently, when the control unit 200 rotates the propeller 140 counterclockwise (reverse direction), the door 150 rotates counterclockwise (reverse direction) from the position where the locking protrusion 165 is inserted into the locking groove 143, and the discharge hole 138 is opened. Therefore, when the first pocket continues to rotate counterclockwise (reverse direction), the first ball pushed by the support pillar 145 falls through the discharge hole 138 and is discharged to the discharge port 116 at the bottom. On the other hand, if the propeller 140 and the door 150 continue to rotate counterclockwise without any restriction after the first ball is discharged through the discharge hole 138, the discharge hole 138 will remain open, and the fifth and fourth balls stored in the adjacent pockets will be discharged in sequence. To prevent this phenomenon, it is preferable that the control unit 200 stops the propeller 140 at a position where the center line of the first pocket coincides with the center line of the discharge hole 138. It is also preferable to form the first stopper 134 of the guide slit 133 at a position where the door 150 can stop immediately after rotating counterclockwise (reversely) and fully opening the discharge hole 138. On the other hand, when the door 150 rotates counterclockwise (reverse direction), as explained above, the contact surfaces 143a, 165a of the locking groove 143 and the locking protrusion 165 are almost perpendicular to the tangential direction, so the locking member 165 does not come out of the locking groove 143. Therefore, the rotation angle of the motor 220 must be precisely controlled to prevent damage to related parts. For example, if the number of pockets is N, the rotation range of the door 150 can be set to 360 / N degrees. In the first embodiment of the present invention, since the propeller 140 has five pockets, the distance between the center lines of the pockets is 72 degrees, and the distance between the open position and the closed position of the door 150 is designed to be 72 degrees so that the door 150 can rotate back and forth within the corresponding range. However, the present invention is not limited to this, and the rotation range of the door 150 and the length of the guide slit 133 can be appropriately determined in consideration of the ejection procedure and ejection method (see FIG. 20(c)). Subsequently, when a command to eject the second ball is generated, the control unit 200 controls the motor 220 to rotate the propeller 140 again in the clockwise direction (forward direction), and since the locking protrusion 165 is inserted into the locking groove 143, the door 150 also rotates in the clockwise direction (forward direction) until it engages with the second stopper 135, thereby hiding the ejection hole 138. If the propeller 140 continues to rotate clockwise (positive direction), the door 150 cannot rotate any further, and the locking protrusion 165 may come out of the locking groove 143 and then be inserted into the locking groove 143 again. The control unit 200 stops the propeller 140 after the second pocket containing the second ball passes through the discharge hole 138 and before the adjacent third pocket passes through the discharge hole 138. Preferably, the propeller 140 is stopped at a position where the center line of the third pocket coincides with the center line of the discharge hole 138 and the locking protrusion 165 is re-inserted into the locking groove 143 of the propeller 140 (see FIG. 20(d)). Next, when the control unit 200 rotates the propeller 140 counterclockwise (reverse direction), the door 150 rotates counterclockwise (reverse direction) from the position where the locking protrusion 165 is inserted into the locking groove 143, and the discharge hole 138 is opened. Therefore, when the second pocket continues to rotate counterclockwise (reverse direction), the second ball pressed against the support pillar 145 falls through the discharge hole 138 and is discharged to the discharge port 116 at the bottom (see FIG. 20(e)). Subsequently, if a command to eject ball No. 3 is generated, the control unit 200 controls the motor 220 to rotate the propeller 140 in a clockwise (forward) direction, and the door 150 also rotates in a clockwise (forward) direction until it contacts the second stopper 135, thereby hiding the ejection hole 138. Next, the control unit 200 stops the propeller 140 after the pocket 3 containing the ball 3 passes through the discharge hole 138 but before the adjacent pocket 4 passes through the discharge hole 138, and then rotates the propeller 140 counterclockwise (reverse direction) to discharge the ball 3 (see FIG. 20(f)). Meanwhile, the toy supply device 100 according to the embodiment of the present invention can check whether toys are present in each pocket of the propeller 140 by using the toy detection sensor 192 installed in the storage container 130. At this time, if a plurality of toy detection sensors are installed vertically, the size of each toy can also be determined. Referring to Figures 21 and 22, first and second item detection sensors 192a and 192b are installed vertically spaced apart on the side wall 132 of the storage container 130, and the propeller 140 can be rotated clockwise at the start of operation and / or at set intervals to detect items inside the pocket. That is, as illustrated in FIG. 21, if an object is detected by the first item detection sensor 192a installed on the lower side but not by the second item detection sensor 192b installed on the upper side, it can be determined that a relatively small first item 10a is stored in the corresponding pocket. Also, as illustrated in Figure 22, if an object is detected by both the first and second item detection sensors 192a, 192b, it can be determined that a relatively large second item 10b is stored in the corresponding pocket. If neither the first nor the second item detecting sensors 192a, 192b detects an object, it can be determined that no item is stored in the corresponding pocket. Meanwhile, although two product detection sensors 192a and 192b are shown installed along the vertical direction in Figures 21 and 22, more product detection sensors may be installed for more precise measurements. 21 and 22 show that the item detection sensors 192a and 192b are installed on the side wall 132 of the storage container 130, but the installation location is not necessarily limited to this. Therefore, as shown in FIG. 23, at least one item detection sensor may be installed on the inner wall of the housing 110. Also, at least one item detection sensor may be installed on the inner wall of the cover 120. FIG. 24 is a block diagram illustrating the control system of the play item dispenser 100 according to the first embodiment of the present invention. Referring to the drawings, the toy supply device 100 according to the first embodiment of the present invention may include a control unit (MCU: Microcontroller Unit) 200, a motor 220, a communication unit 230, a speaker 174, an LED 176, an ejection detection sensor 178, an animal detection sensor 190, a toy detection sensor 192, a bus 290, etc. The MCU 200 includes a processor 210 and a memory 212. The processor 210 executes a computer program stored in the memory 212 to perform predetermined calculations and data processing. The type of memory 212 is not particularly limited, and various types such as ROM, RAM, register, and cache memory may be used selectively or in combination. The processor 210 and the memory 212 may be fabricated or packaged on a single chip, or may be mounted on a board while being separated from each other. The memory 212 stores various control programs, various parameters, data, etc. for the operation of the toy supplying device 100. The memory 212 may also store message data or sound data to be output through the speaker 174 or transmitted through the communication unit 230. The control program stored in the memory 212 may include an operating system, middleware, an application, or an application programming interface (API) as a set of instructions executed by the processor 210 . On the other hand, in terms of functionality, the MCU 200 may include a motor control unit 251, an item detection and judgment unit 252, an animal detection and judgment unit 253, an ejection target determination unit 254, an ejection or not judgment unit 255, a message transmission unit 256, an audiovisual effect control unit 257, etc., as shown in the block diagram of Figure 25. When a product discharge command is generated or received, the motor control unit 251 controls the motor 220 to rotate the propeller 140 in the forward or reverse direction by a set angle. Since the rotation angle of the motor 220 varies depending on the position of the article to be discharged, it is preferable to store the reference position information of each pocket of the propeller 140 in the memory 212 when setting up the device. As described in relation to Figures 21 and 22, the item detection and judgment unit 252 detects the position of items using the item detection sensor 192 at the beginning of operation and / or at set intervals, or determines whether items are present inside each pocket or the size of the items. The animal detection and determination unit 253 determines whether an animal is present around the device or the size of the animal using the animal detection sensors 190 installed around the housing 110 . The discharge target determination unit 254 plays a role in determining the type and size of the product to be discharged according to the set conditions. For example, if the animal detection and determination unit 253 determines that a small animal is relatively close, the position of the small item set for the small animal can be confirmed based on the determination result of the item detection and determination unit 252, and the item to be discharged can be determined based on the position of the small item set for the small animal based on the determination result of the item detection and determination unit 252. Also, if there are two or more small items, the item that can be discharged the fastest can be determined as the item to be discharged. The discharge determination unit 255 determines whether the items have been properly discharged using the discharge detection sensor 176 installed in the discharge guide 180. If the discharge detection sensor 176 does not detect the discharge of items within a set time from the time the door 150 rotates and the discharge hole 138 opens, it can generate a discharge error message and transmit it to the message transmission unit 256. The message transmission unit 256 generates a predetermined message according to the set conditions and sends it through the communication unit 230. For example, when all the items are used up or an error occurs in the discharge, an error message can be sent through the communication unit 230 to the user's portable terminal or a wall pad installed in the home. The audiovisual effect control unit 257 can generate audiovisual effects by controlling the speaker 174 or the LED 176 according to the set conditions. For example, when the item release period has arrived, an audio signal to call the pet can be output through the speaker 174, and when the item is released, a visual effect can be generated by controlling the LED 176. At least one of the functions of the MCU 200 may be provided in the form of a program stored in the memory 212 and executed by the processor 210. Also, at least one of the components may be provided in the form of hardware specially designed for high-speed operation, or may be provided in the form of an integration of software and hardware. Meanwhile, the communication unit 230 may be designed to support various communication methods regardless of whether they are wired or wireless, and regardless of the type of communication protocol. For example, the communication unit 230 may be configured to be connected to at least one of a short-range wireless communication network (such as Wi-Fi, Bluetooth, SIGBEE, Z-Wave, or IrDA), a low-power long-range communication network (such as LoRa, LTE-M, LTE Cat. M1, or NB-IoT), an Internet network, a mobile communication network, a dedicated communication network, or a private communication network. The bus 290 is a path for transmitting data or electrical signals between the components of the toy supply device 100, and can be provided in the form of a circuit pattern or a cable. In addition, in the above description, it was explained that the MCU, i.e., the control unit 200, can send audiovisual effects through the speaker 174 or LED 176 depending on the set conditions, and here the set conditions can correspond to the occurrence of the release of items (i.e., toys). That is, when the control unit 200 controls the motor 220 etc. to discharge the product through the discharge hole 138, it can control the speaker 174 to send a predetermined sound signal to emit a corresponding sound to the outside. At this time, the sound emitted through the speaker 174 may be, for example, the sound of an elevator, footsteps in a hallway, etc. That is, every time a nose work ball, which is a toy, is discharged through the outlet, the external stimulating sound that normally stimulates the pet is emitted through the speaker 174, thereby gradually reducing stress caused by the external stimulating sound and reducing the pet's sensitivity to the external stimulating sound. If a plurality of external stimulus sounds are stored, the control unit 200 can select them randomly or in a preset order, and the type and sequence of the sounds can be specified by the user. For example, the above-mentioned communication unit 230 can communicate with a communication terminal (not shown) operated by the user, and the control unit 200 can store an external stimulation sound file received from the corresponding communication terminal through the communication unit 230, and then play the stored external stimulation sound file and emit it through the speaker 174 every time the nose work ball is discharged. In particular, the control unit 200 can adjust the frequency of emitting the external stimulus sound over time. For example, at the beginning of the operation of the control unit 200, the companion animal is not yet accustomed to the external stimulation sound, so the external stimulation sound can be emitted occasionally (e.g., once every 10 ejections of the nose work ball), and as time passes, the frequency of the external stimulation sound emission can be gradually increased (e.g., once every 5 ejections of the nose work ball → once every 2 ejections of the nose work ball). Furthermore, the control unit 200 may discontinue emission of the stimulus sound once the companion animal has become accustomed to the external stimulus sound and no longer shows any negative reactions. In addition, the control unit 200 can adjust the volume of the external stimulus sound when it is emitted according to a predetermined condition. For example, the volume of the external stimulus sound may be low at the beginning of the operation of the control unit 200 and may be increased over time. <Second Example> The second embodiment of the toy supply device 100a of the present invention differs from the first embodiment in that, as illustrated in FIG. 26, first and second discharge holes 138a, 138b are formed in the storage container 130 and first and second doors 150a, 150b are installed to open and close each discharge hole 138a, 138b. The container 130 and the propeller 140 are the same as those in the first embodiment, so a description thereof will be omitted. By forming the two discharge holes 138a and 138b as described above, products can be discharged in more various ways than in the first embodiment. The first door 150a and the second door 150b are each rotatably installed inside the receiving container 130 by connecting a ring-shaped connecting member 154 around a circular pipe 154 provided at the center of the receiving container 130, similar to the door 150 of the first embodiment. In addition, a first locking member 160a and a second locking member 160b are attached to the first door 150a and the second door 150b, respectively, and the first and second locking members 160a and 160b each have the same shape as the locking member 160 of the first embodiment and are connected to each door 150a and 150b in the same manner. Figure 27 shows the state with the propeller 140 removed, and the side wall 132 of the storage container 130 is formed with a first guide slit 133a into which the edge of the first door 150a is inserted and a second guide slit 133b into which the edge of the second door 150b is inserted. Therefore, the rotation range of the first door 150a is limited by the first stopper 134a and the second stopper 135a provided on one side and the other side of the first guide slit 133a, respectively. Similarly, the rotation range of the second door 150b is limited by a first stopper 134b and a second stopper 135b provided on one side and the other side of the second guide slit 133a, respectively. In the second embodiment of the present invention, it is preferable that the lengths of the first and second guide slits 133a and 133b are longer than the guide slit 133 of the first embodiment. This is because, in order to prevent the two discharge holes 138a and 138b from being opened at the same time, the first door 150a and the second door 150b need to be rotated within a different angle range from that in the first embodiment. On the other hand, if two discharge holes 138a and 138b are formed in this manner, two discharge guides 180a and 180b communicating with each of the discharge holes 138a and 138b must be installed inside the housing 110 as illustrated in FIG. 28. In this case, the lower ends of the two discharge guides 180a and 180b can be connected to separate discharge ports 116, or as shown in the drawing, they can be connected to a single discharge guide 180 inside the housing 110 and products can be discharged through a single discharge port 116. The operation of the play item supplying device 100a according to the second embodiment of the present invention will be described below with reference to FIG. For ease of explanation, it is assumed that the propeller 140 has five pockets, each containing one nosework ball. It is also assumed that, at the beginning of operation, the first door 150a and the second door 150b are in positions that hide the first discharge hole 138a and the second discharge hole 138b, respectively, and are unable to rotate further clockwise due to the second stoppers 135a and 135b. Also, to prevent the two discharge holes 138a, 138b from being opened simultaneously, it is assumed that the center line of the first discharge hole 138a coincides with the center line of any pocket at the beginning of operation, while the center line of the second discharge hole 138a coincides with the center line of the support post 145 between the pockets. In this case, as shown in Figure 29(a), the first locking member 160a of the first door 150a hiding the first discharge hole 138a has its locking protrusion 165 inserted into the locking groove 143 of the propeller 140, and the second locking member 160b of the second door 150b hiding the second discharge hole 138b has its locking protrusion 165 removed from the locking groove 143 of the propeller 140. In this state, if a command to eject ball No. 1 is generated, the device's control unit 200 controls the motor 220 to rotate the propeller 140 clockwise (forward). In this case, the first door 150a and the second door 150b are caught by the second stoppers 135a and 135b, respectively, and cannot rotate any further, and the process of the locking protrusions 165 of the locking members 160a and 160b being released from the locking grooves 143 and then inserted into the locking grooves 143 can be repeated (see FIG. 29(a)). Next, the control unit 200 stops the propeller 140 after the No. 1 pocket containing the No. 1 ball passes through the first discharge hole 138a and before the adjacent No. 2 pocket passes through the second discharge hole 138a. Preferably, the center line of the second pocket and the center line of the first discharge hole 138a are aligned, and the propeller 140 is stopped at a position where the locking protrusion 165 is inserted into the locking groove 143 of the propeller 140 again (see (b) of FIG. 29). Subsequently, when the control unit 200 rotates the propeller 140 counterclockwise (reverse direction), the first door 150a rotates counterclockwise together with the propeller 140 because the locking protrusion 165 of the first locking member 160a is inserted into the locking groove 143. As a result, the first discharge hole 138a is opened, and the first ball pressed against the support post 145 falls through the first discharge hole 138a and is discharged to the discharge port 116 at the bottom. On the other hand, since the locking protrusion 165 of the second locking member 160b is out of the locking groove 143, the second door 150b is stopped at the beginning of the counterclockwise (reverse) rotation of the propeller 140, and after the propeller 140 rotates approximately 36 degrees and the locking protrusion 165 is inserted into the locking groove 143, the second door 150b begins to rotate counterclockwise together with the propeller 140. Now, assuming that the propeller 140 rotates 72 degrees, which corresponds to the centerline distance between the pockets, the first door 150a rotates 72 degrees while the second door 150b rotates only 36 degrees, so that the first discharge hole 138a is fully opened while the second discharge hole 138b is only half-open. Therefore, if each pocket contains more than half the size of each of the discharge holes 138a and 138b, the items will be discharged through the first discharge hole 138a in the above case (see FIG. 29(c)). Subsequently, when a command to eject the second ball is generated, the control unit 200 controls the motor 220 to rotate the propeller 140 again in the clockwise direction (forward direction), and during this process, the first and second doors 150a and 150b rotate clockwise together with the propeller 140 because the locking members 165 of the first and second locking members 160a and 160b, respectively, are engaged in the locking grooves 143. During this process, the first discharge hole 138a, which was fully opened, and the second discharge hole 138b, which was only half opened, are hidden by the first door 150a and the second door 150b, respectively. When the propeller 140 is rotated clockwise (forward), the second door 150b rotates clockwise by approximately 36 degrees and then engages the second stopper 135b, preventing it from rotating any further. At this time, the locking protrusion 165 of the second locking member 160b is released from the locking groove 143. After rotating clockwise by approximately 72 degrees, the first door 150a is stopped by the second stopper 135a and cannot rotate any further. The control unit 200 stops the propeller 140 after the second pocket containing the second ball passes through the first discharge hole 138a and before the adjacent third pocket passes through the first discharge hole 138. Preferably, the propeller 140 is stopped at a position where the center line of the third pocket coincides with the center line of the first discharge hole 138 and the locking protrusion 165 of the first locking member 160a is inserted into the locking groove 143 of the propeller 140 again (see (d1) in FIG. 29). Next, when the control unit 200 rotates the propeller 140 counterclockwise (reverse direction) by about 72 degrees, the first door 150a rotates counterclockwise together with the propeller 140 because the locking protrusion 165 of the first locking member 160a is inserted into the locking groove 143. As a result, the first discharge hole 138a is opened, and the second ball pressed against the support pillar 145 falls through the first discharge hole 138a and is discharged to the discharge port 116 at the bottom. Meanwhile, since the locking protrusion 165 of the second locking member 160b of the second door 150b is out of the locking groove 143, the propeller 140 rotates counterclockwise (backward) by approximately 36 degrees, and the locking protrusion 165 rotates counterclockwise together with the propeller 140 from the position where it was inserted into the locking groove 143, thereby opening the second discharge hole 138b only halfway (see FIG. 29(e)). According to the above-described discharging method, the products are discharged only through the first discharge hole 138a, so there is no significant difference from the first embodiment. However, the plaything dispenser 100a according to the second embodiment of the present invention can also dispense items in a manner different from that of the first embodiment. That is, after the propeller 140 is rotated 72 degrees counterclockwise (reverse direction) in step (c) of Figure 29 to discharge ball No. 1 through the first discharge hole 138a, if the propeller 140 is rotated another 36 degrees counterclockwise (reverse direction), the second discharge hole 138b, which was only half-open in the previous step, is fully opened, and ball No. 3 in pocket No. 3 can be discharged through the second discharge hole 138b. At this time, since the first discharge hole 138a is only half-open due to the first door 150a, no balls are discharged through the first discharge hole 138a (see (d2) of Figure 29). This process assumes that the locking protrusion 165 can be removed from the locking groove 143 when additional rotation in the reverse direction (counterclockwise) occurs even though the stopper is engaged. Therefore, according to the second embodiment of the present invention, by appropriately selecting the methods (d1) and (d2) of FIG. 29, it is possible to discharge the products in a more diverse sequence than in the first embodiment. On the other hand, when two discharge holes, i.e., a first discharge hole 138a and a second discharge hole 138b, are formed in the positions shown in FIG. 28, the nose work ball 10 falling through the first discharge hole 138a slides down along the right discharge guide 180a and is discharged through the discharge port 116, and the nose work ball 10 falling through the second discharge hole 138b slides down along the left discharge guide 180b, collides with the left discharge guide 180b, slows down, and then slides down again to be discharged through the discharge port 116. That is, the nose work balls 10 dropping through the second discharge hole 138b are discharged through the discharge port 116 at a slower speed than the nose work balls 10 dropping through the first discharge hole 138a. By discharging the nose work balls 10 at various speeds in this way, it is possible to provide a sense of enjoyment to the companion animal and also to improve the learning efficiency of the companion animal. <Third Example> The toy supplying device 100' according to the third embodiment of the present invention may be configured by adding a configuration for controlling the speed at which the toys are dispensed to the first embodiment. That is, in the previous second embodiment, the nose work balls 10 were discharged through the discharge port 116 at different speeds by dropping them through two discharge holes 138a and 138b, but in this third embodiment, a configuration has been added to allow the nose work balls 10 to be discharged at different speeds from just one discharge hole 138, as in the first embodiment. For this purpose, the ejection guide 180 may further include a locking portion 181 formed on the ejection guide 180 and a locking driver 182 for performing a protruding operation of the locking portion. Here, the latching portion 181 is formed in one area of ​​the discharge guide 180, and may be provided in the middle of the discharge guide 180 as shown in FIGS. For reference, FIG. 30 is a cross-sectional view and FIG. 31 is a perspective view. That is, the latching portion 181 may be formed to almost exactly fit the size of the through-groove 183 formed in the discharge guide 180 and may be in contact with one side of the corresponding through-groove 183 . The locking portion 181 can rotate around one side as a central axis, and can stay in a position (position A) that is aligned with the surface of the discharge guide 180 as shown in Figure 32, or in a position (position B) where the other side is raised at a predetermined angle from the surface of the discharge guide 180. In particular, when the nose work ball 10 is at position B, it descends along the discharge guide 180 and collides with the stopper 181, causing its speed to slow down. The degree of deceleration varies depending on the degree (angle) at which the other side of the stopper 181 rises outward. A locking driver 182 is provided for the operation of the locking part 181, and can be configured to include a motor 1821 and a long shaft 1823 connected to the shaft 1822 of the motor 1821 as shown in FIG. 31. Here, although the cross section of the long shaft 1823 is not clearly shown in Figure 31, it can be connected to the motor shaft, penetrate the side of the discharge guide 180, and then penetrate and inserted into one side of the locking portion 181. As a result, the rotational power of the motor is transmitted to one side of the locking part, causing rotational motion around that side, resulting in movement of the locking part as shown in Figure 32. The rotational movement of the motor 1821 is controlled by the control unit 200, which controls the operation of the locking drive unit 182 to adjust the degree to which the other side of the locking unit 181 protrudes outward, i.e., the degree to which it rises upward. Meanwhile, a friction-inducing member may be attached to the upper end surface of the stopper 181 in order to further reduce the moving speed of the nose work ball 10 that hits the stopper. For example, as shown in FIG. 33, a plurality of filament-type members 1811 may be attached to the upper surface of the latching portion 181. In this case, more friction is generated during the movement of the nose work ball 10 compared to a slippery surface, which significantly reduces the speed of the nose work ball 10. FIG. 34 shows the operating state of the locking part 181 to which the wool-type member 1811 is attached. Meanwhile, in the above-described embodiment, the other side of the locking portion 181 is protruded from the surface of the discharge guide 180 by a rotational movement centered on one side of the locking portion 181, but the protrusion operation can also be performed by the entire locking portion 181 moving up and down at the same time. Such an example is shown in FIGS. As shown in the drawings, a through groove 183' is formed in a portion of the middle of the discharge guide 180', and the engaging portion 181' has a size corresponding to the through groove 183' of the discharge guide 180' and moves up and down in a direction perpendicular to the surface of the corresponding discharge guide 180'. At this time, the locking driver 182' is coupled with at least a part of the locking part 181' to perform a protruding operation above the through groove of the locking part 181'. Of course, such an operation of the locking drive unit 182' is performed by the control unit 200 described above. That is, the control unit 200 can adjust the degree of outward protrusion of the locking portion 181' by controlling the operation of the locking driver 182'. Referring to FIG. 35, a long shaft 1823' is connected to a motor 1821' of the locking driving part 182, and the long shaft 1823' is attached to the bottom surface of the locking part 181'. The motor 1821' of FIG. 35 includes a gearbox (not shown) that converts rotary motion into linear motion, and the up and down motion of the long shaft 1823' can be generated by a control signal from the control unit 200. FIG. 36 shows a state in which the locking portion 181' has moved vertically with respect to the surface of the discharge guide 180' due to such upward movement of the long shaft 1823'. That is, due to the protruding movement of the stopper 181', the nose work ball 10 descending along the discharge guide 180' collides with a part of the stopper 181', thereby slowing down. In particular, as shown in Figures 35 and 36, if a friction-inducing member (for example, a plurality of wool-type members) is attached to the upper surface of the engaging portion 181', the nose work ball 1010 can be decelerated even more significantly. The process of deceleration while passing through the wool-type member is shown in Figure 37. <Fourth Example> As shown in the block diagram of FIG. 38, the plaything dispenser 100 according to the fourth embodiment of the present invention includes a first motor 220a for rotating the propeller 140 and a second motor 220b for rotating the door 150, and the control unit 200 can operate the first motor 220a and the second motor 220b individually. In this way, when the door 150 and the propeller 140 are rotated independently, the locking member 160 that functions to link the door 150 and the propeller 140 in the first to third embodiments can be omitted. In addition, when there are two or more doors 150, a plurality of motors 220 for individually operating the plurality of doors 150 may be included. Although the preferred embodiment of the present invention has been described above, the present invention is not limited thereto and can be variously modified or altered in the course of specific applications. For example, in the embodiment described above, a plurality of locking grooves 143 are formed in the center block 141 of the propeller 140 and locking protrusions 165 are formed in the locking member 160, but this is not necessarily limited to this. Conversely, locking protrusions may be formed protruding from the center block 141 of the propeller 140 and corresponding locking grooves may be formed in the locking member 160. However, even in this case, it is of course preferable that both side surfaces of the locking protrusions and both inner side surfaces of the locking grooves have different inclinations. As another example, in the embodiment described above, the door 150 rotates together with the propeller 140 only when the propeller 140 rotates counterclockwise (reverse direction), but this is not necessarily limited to this. For example, by forming gentle slopes at opposite positions on the locking groove 143 and the locking protrusion 165 and adjusting the position of the guide slit 133 of the receiving container 130, the door 150 and the propeller 140 can rotate together only when the propeller 140 rotates clockwise (forward direction). As another example, in the above-described embodiment, guide slits 133 of a predetermined length are formed along the inner wall of receiving container 130 to limit the rotation range of door 150, but the present invention is not limited to this. For example, a stopper that limits the rotation range of door 150 may be formed as a protrusion on the bottom of receiving container 130, in which case side wall 132 of receiving container 130 and guide slits 133 may be omitted. As another example, although the door 150 is installed inside the receiving container 130 in the above-described embodiment, it is not limited to this and can be installed at the bottom of the receiving container 130. However, in this configuration, the center block 141 of the propeller 140, in which the locking groove 143 is formed, must protrude to the bottom of the receiving container 130, which makes the structure somewhat complicated. As another example, although the motor 220 is installed at the bottom of the storage container 130 in the embodiment described above, this is not necessarily limited to this, and the motor 220 can also be installed at the top of the storage container 130, i.e., inside the cover 120. As another example, although the circular pipe 137 having a predetermined height is formed in the center of the receiving container 130 in the above-described embodiment, the present invention is not limited to this. For example, only the through-hole 136 may be formed in the center of the receiving container 130, and a circular pipe inserted into the through-hole 136 may be formed in the ring-shaped connecting member 156 of the door 150. As another example, although the toy dispensers 100, 100a, and 100b according to the embodiments of the present invention are developed for dispensing nose work balls, their applications are not necessarily limited to this, and they can also be used for dispensing other types of toys or toys.
