Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, and in particular to a portable ejector feeding device. Background Technology

[0002] Material dispensing devices are typically used for storing and dispensing food items such as candy and chewing gum. These devices include storage space that can hold multiple units. Traditional dispensing devices usually use simple plastic boxes or aluminum foil packaging. While these packaging methods meet the basic needs of preserving and carrying food items like chewing gum and candy, users often need to manually open the packaging to retrieve food items from the storage space, and then reseal it after each item is taken out. This frequent manual opening and closing of the packaging is particularly inconvenient when one-handed operation or multitasking is required, resulting in a poor user experience.

[0003] To address the aforementioned issues, existing technology provides a candy box where the lid and base can be opened and closed via a magnetic connection. During use, a gentle press ejects the candy from the container, making it relatively convenient. However, the candy still encounters significant resistance when being ejected from the container, making it difficult to guarantee a smooth and rapid ejection.

[0004] Therefore, there is an urgent need to design a portable ejection device to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this invention is to provide a portable ejection device that can further improve the efficiency of material ejection and the reliability of ejection, thereby enhancing the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A portable ejector feeding device includes a storage box and a lid rotatably hinged to the storage box. The storage box has a communicating storage cavity and an ejector outlet. The storage cavity is used to store material. The lid is provided with a first magnetic attraction structure and a pressing pusher. The first magnetic attraction structure magnetically engages with the storage box to seal the ejector outlet. The storage box is also provided with a guide slope that gradually slopes in the direction from the ejector outlet to the outside of the ejector outlet. When the lid is pressed to rotate relative to the storage box, the first magnetic attraction structure can release its magnetic connection with the storage box, and the pressing pusher can eject the material from the storage box via the guide slope in the direction toward the ejector outlet.

[0008] Preferably, the storage box includes a storage body, a connecting part, and a supporting part, wherein:

[0009] The storage body has the storage cavity;

[0010] Two connecting parts are provided and are spaced apart at the top opening of the storage body, and the top ends of the two connecting parts are simultaneously connected to the support part;

[0011] The storage body, the connecting part, and the supporting part are respectively connected to form the ejector outlet and the opening space on both sides of the storage body. The opening space is connected to the ejector outlet. The box cover is rotatably hinged to the supporting part so that the extrusion pusher is rotatably disposed in the opening space. The bottom of the supporting part is provided with the guide slope.

[0012] Preferably, the bottom of the support portion is provided with a guide wing plate protruding outwards, and the bottom surface of the guide wing plate is inclined to form the guide slope.

[0013] Preferably, two guide vanes are provided, and the two guide vanes are spaced apart at the bottom of the support.

[0014] Preferably, the support portion has a stop on the side facing the extrusion pusher.

[0015] Preferably, the support is provided with a pivot, and the inside of the cover is provided with a transition slot. The pivot is rotatably inserted into the transition slot to achieve a rotatable hinged connection between the cover and the support.

[0016] Preferably, the support portion has a notch on the side away from the stop block, and the inside of the lid has a positioning protrusion. When the pressing force on the lid is removed and the lid rotates relative to the support portion, the positioning protrusion can be inserted into the notch.

[0017] Preferably, the support portion is provided with a second magnetic structure with the opposite magnetic pole to the first magnetic structure, and the second magnetic structure is disposed opposite to the first magnetic structure. The first magnetic structure can release its magnetic connection with the second magnetic structure to expose the ejector outlet; or, the first magnetic structure can magnetically connect with the second magnetic structure to cover the ejector outlet.

[0018] Preferably, the portable ejector discharge device further includes a side housing, which is located on one side of the storage body. The storage body has a movable groove in the vertical direction on the side facing the side housing. An elastic support is slidably provided inside the side housing, and one end of the elastic support extends into the storage cavity. The material in the storage cavity can move up and down in the storage cavity under the action of the elastic support.

[0019] Preferably, the support portion includes a slider, a support body, and an elastic element. The slider is slidably disposed on the side housing and connected to the support body. One end of the support body extends into the storage cavity. One end of the elastic element is connected to the support body, and the other end of the elastic element is connected to the end of the side housing. The elastic element is configured to have an elastic preload that drives the support body to rise toward the spring outlet.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model provides a portable ejector feeding device. In use, simply pressing the lid opens it. Releasing the pressure allows the lid to automatically snap onto the storage box under the magnetic attraction of a first magnetic structure. Compared to existing methods using latches and springs, this eliminates the need for latches and springs, resulting in a simpler overall structure. Furthermore, the presence of a guide ramp on the storage box helps the extruder push material out of the ejector outlet more quickly, allowing for smoother and faster material removal and preventing jamming at the outlet. This improves efficiency and reliability, enhancing the user experience. Attached Figure Description

[0040] The specific solutions provided by this utility model will be described below with reference to the accompanying drawings and detailed embodiments.

[0041] Combination Figures 1 to 7 As shown, this embodiment provides a portable ejector dispensing device, which includes a storage box 1 and a lid 2 rotatably hinged to the storage box 1. The storage box 1 has a communicating storage cavity 101 and an ejector outlet 102. The storage cavity 101 extends vertically to store materials, such as chewing gum, candy, or pills in block or pellet form. The materials can exit the storage box 1 through the ejector outlet 102 for consumption or distribution by the user. The lid 2 is provided with a first magnetic attraction structure 21 and a pressing pusher 22. The first magnetic attraction structure 21 is preferably a magnet. The first magnetic attraction structure 21 magnetically engages with the storage box 1 to seal the ejector outlet 102, preventing materials from falling out of the ejector outlet 102 during normal carrying, thus achieving material storage. When the lid 2 is pressed to rotate relative to the storage box 1 and expose the ejector outlet 102, the extrusion pusher 22 can push the material out in the direction of the ejector outlet 102, and the material stored in the storage cavity 101 can be taken out.

[0042] Specifically, in this embodiment, reference is made to... Figures 3 to 5 As shown, the storage box 1 includes a storage body 11, a connecting part 12, and a supporting part 13. The storage body 11 has the aforementioned storage cavity 101. Two connecting parts 12 are provided, which are spaced apart at the top opening of the storage body 11. The top ends of the two connecting parts 12 are simultaneously connected to the supporting part 13 to form an "n"-shaped structure. The storage body 11, the connecting part 12, and the supporting part 13 are respectively connected to form an opening space 103 and a spring outlet 102 on both sides of the storage body 11. The opening space 103 and the spring outlet 102 are connected. The box cover 2 is rotatably hinged to the supporting part 13 so that the pressing push block 22 is rotatably disposed in the opening space 103. When the box cover 2 is pressed to rotate relative to the supporting part 13, the spring outlet 102 is exposed, and the pressing push block 22 can push the material to push the material out of the spring outlet 102.

[0043] To achieve a hinged connection between the lid 2 and the support 13, one embodiment of this invention is as follows: (Refer to...) Figure 5 , Figure 6 As shown, two rotating shafts 131 are arranged opposite to each other on the support part 13, and two connecting slots 23 are recessed opposite to each other on the inner side wall of the cover 2. The connecting slots 23 and the rotating shafts 131 are arranged opposite to each other, and the rotating shafts 131 are rotatably inserted into the opposite connecting slots 23, thereby realizing the rotatable hinged connection between the cover 2 and the support part 13. Through the above arrangement, not only is the connection stability between the support part 13 and the cover 2 improved, but the structure is also simple and easy to implement, effectively simplifying the construction of the device.

[0044] Further, refer to Figure 4 , Figure 6 As shown, the support part 13 is also provided with a second magnetic structure 14 with the opposite magnetic pole to the first magnetic structure 21. The second magnetic structure 14 is arranged opposite to the first magnetic structure 21. When the lid 2 is pressed to rotate relative to the storage body 11, the first magnetic structure 21 can release the magnetic connection between the second magnetic structure 14 to expose the ejector outlet 102. Alternatively, when the pressing force on the lid 2 is removed, the first magnetic structure 21 can drive the lid 2 to rotate in the direction toward the storage body 11 under the magnetic force of the second magnetic structure 14, so that the first magnetic structure 21 restores the magnetic connection with the second magnetic structure 14, thereby closing the ejector outlet 102.

[0045] Furthermore, a stop 132 is provided on the side of the support 13 facing the pressing push block 22. The stop 132 can limit the rotation range of the lid 2 by restricting the rotation angle range of the pressing push block 22. If the rotation angle of the lid 2 is too large, the magnetic attraction between the second magnetic structure 14 and the first magnetic structure 21 will be reduced too much or even disappear, resulting in the lid 2 not being able to automatically return to its original position after the pressing force of the lid 2 is removed, thus affecting its use. By setting the stop 132, the rotation angle of the lid 2 can be controlled within a suitable range, ensuring that after the pressing force of the lid 2 is removed, the second magnetic structure 14 can still restore the magnetic connection with the first magnetic structure 21 through the magnetic attraction, thereby realizing the automatic return function of the lid 2 and ensuring the user's user experience.

[0046] Furthermore, in this embodiment, a guide slope 133 is provided at the bottom of the support part 13. The guide slope 133 is gradually inclined in the direction from the ejector outlet 102 to the outside of the ejector outlet 102. The extrusion pusher 22 can push the material out of the storage body 11 in the direction towards the ejector outlet 102 through the action of the guide slope 133. The guide slope 133 ensures that the material can smoothly slide along the slope when pushed by the extrusion pusher 22, reducing the resistance encountered by the material during ejection, thereby further reducing the difficulty of material removal and improving material ejection efficiency. This allows the device to accommodate thicker and larger materials, effectively expanding the applicability of the device. Of course, it is understood that the inclination of the guide slope 133 can be adjusted according to the characteristics of different materials to adapt to different types and viscosities of materials, ensuring that the material is pushed out smoothly and accurately each time.

[0047] In one embodiment of this invention, a guide wing plate 134 protrudes from the bottom of the support portion 13. The bottom surface of the guide wing plate 134 is inclined, so that the bottom surface of the guide wing plate 134 forms the aforementioned guiding slope 133. Since the support portion 13 provided in this embodiment has a plate-like structure, the provision of the guide wing plate 134 not only meets the requirement of providing a guiding slope 133 on the support portion 13, but also effectively improves the structural strength of the support portion 13, preventing deformation or damage to the support portion 13 during use, thereby increasing the service life of the entire device.

[0048] Preferably, two guide vanes 134 are provided, and the two guide vanes 134 are spaced apart at the bottom of the support 13, so that the material can slide more smoothly along the guide slope 133 and be pushed out.

[0049] Furthermore, in this embodiment, reference is made to... Figure 5 , Figure 6 As shown, a notch 135 is provided on the side of the support 13 away from the stop block 132, and a positioning protrusion 24 is provided inside the lid 2. When the pressing force on the lid 2 is removed, allowing the lid 2 to rotate relative to the support 13, the positioning protrusion 24 can be inserted into the notch 135 to ensure that the lid 2 can automatically return to the initial closed position. The cooperation between the positioning protrusion 24 and the notch 135 gives the lid 2 a good positioning effect when closed, avoiding shaking or misalignment of the lid 2 during the closing process, and ensuring the long-term reliability of the device.

[0050] Optionally, the storage box 1 provided in this embodiment also includes a side housing 3. The side housing 3 is located on one side of the storage body 11. The storage body 11 is provided with a movable groove 111 in the vertical direction on the side facing the side housing 3. An elastic support part 4 is slidably provided inside the side housing 3. One end of the elastic support part 4 extends into the storage cavity 101. The material in the storage cavity 101 can move up and down in the storage cavity 101 under the action of the elastic support part 4, so that when the ejector outlet 102 is opened, the material is pushed upward under the action of the elastic support part 4, thereby facilitating the removal of the material in the storage cavity 101.

[0051] Furthermore, a bottom support block 5 is provided at the bottom of the side housing 3. The bottom support block 5 is preferably integrally formed with the side housing 3 so that the side housing 3 and the bottom support block 5 can be connected to form an "L" shaped structure. The bottom support block 5 makes the connection between the storage body 11 and the bottom support block 5 more stable.

[0052] Specifically, in this embodiment, reference is made to... Figure 7 As shown, the elastic support part 4 includes a slider 41, a support body 42, and an elastic member 43. The slider 41 is slidably disposed on the side cover housing 3 and connected to the support body 42. One end of the support body 42 away from the slider 41 extends through the movable groove 111 and is disposed in the storage cavity 101. One end of the elastic member 43 is connected to the support body 42, and the other end of the elastic member 43 is connected to the end of the side cover housing 3. The elastic member 43 has an elastic preload force that drives the support body 42 to rise toward the spring outlet 102.

[0053] For example, in one embodiment of this invention, the elastic element 43 is a coil spring, the supporting body 42 is a long strip-shaped structure, and a slider 41 is provided on each side of the supporting body 42. The bottom of the supporting body 42 is fixedly connected to one end of the coil spring, and the other end of the coil spring is connected to the top of the side cover shell 3. In actual use, when materials are placed into the storage cavity 101 in sequence, the materials will press down on the supporting body 42 until the storage cavity 101 is full of materials. At this time, the supporting body 42 is pressed to the bottom position, and the coil spring has an elastic preload force to drive the supporting body 42 to rise. Then, when the box cover 2 is opened to expose the ejector outlet 102, the materials at the top of the storage cavity 101 can be taken out from the ejector outlet 102. When one piece is taken out, the coil spring will contract after losing a certain pressure, thereby lifting the subsequent materials upward through the supporting body 42, and then lifting the materials below to the top of the storage cavity 101. Finally, release the pressure on the lid 2. At this time, the lid 2 can be reset and the pop-out outlet 102 will be sealed. With the above settings, the material can be easily taken out from the storage cavity 101.

[0054] Furthermore, the side wall of the side housing 3 is provided with a limiting groove 31 in the vertical direction. The slider 41 is slidably disposed in the limiting groove 31. The limiting groove 31 makes the supporting body 42 move up and down more stably inside the side housing 3, preventing shaking.

[0055] Optionally, the portable ejector feeding device provided in this embodiment also includes an outer box 6, which has a receiving space 61 for accommodating the storage box 1, so as to facilitate carrying and use, and at the same time plays a role in protecting the storage box 1 and the materials, thus improving safety.

[0056] The working principle of this utility model is as follows: Taking a piece of chewing gum as an example, the chewing gum is placed in the storage cavity 101. When the chewing gum needs to be taken out, the lid 2 is pressed, and the lid 2 will drive the insertion slot to rotate relative to the support part 13. At this time, the first magnetic attraction structure 21 on the lid 2 and the second magnetic attraction structure 14 on the support part 13 will be demagnetized. Therefore, the pop-out outlet 102 and the storage cavity 101 will be exposed as the lid 2 rotates. Since the lid 2 is provided with a pressing push block 22, the lid 2 will drive the pressing push block 22 to rotate synchronously during the rotation. During the rotation, the pressing push block 22 will push the chewing gum from the storage cavity 101 to the pop-out outlet 102. During the movement of the chewing gum towards the pop-out outlet 102, since the bottom of the support part 13 is provided with a guide slope 133, the guide slope 133 can assist the chewing gum to slide smoothly towards the pop-out outlet 102, thereby enabling the chewing gum to be taken out quickly. After removing the chewing gum block at the top, release the pressing force on the lid 2. At this time, the lid 2 will cause the insertion slot to rotate relative to the storage body 11 until the first magnetic structure 21 and the second magnetic structure 14 are magnetically connected, so that the lid 2 closes the ejector outlet 102 and the storage cavity 101 again.

[0057] With the above-mentioned configuration, the portable ejector feeding device of this application can be used by simply pressing lightly to open the lid 2. After the pressing force is released, the lid 2 can automatically close onto the storage box 1 under the magnetic attraction of the first magnetic structure 21 and the second magnetic structure 14. Compared with the existing method of opening and closing the lid 2 through a latch structure and spring, the latch structure and spring are eliminated, making the overall structure simpler. More importantly, under the action of the guide slope 133, the guide slope 133 can help the extrusion pusher 22 push the material out of the ejector outlet 102 more quickly, so that the material can be taken out more smoothly and quickly, avoiding the situation where the material is stuck at the ejector outlet 102. The extraction efficiency and reliability are higher, thereby further improving the user experience.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
