[0028] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0029] An embodiment of the present invention provides a straw box device. Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the straw box device includes a storage box 10 for storing straws and a driving mechanism 30. The storage box 10 includes a first side wall 11 and a second side wall 12 which are oppositely arranged, a first end 13 and a second end 14 which are oppositely arranged, and a bottom plate at the bottom. The side walls and the ends enclose a storage space for storing straws. The storage space includes a transition space 101 for storing the straws to be discharged. An outlet 131 for the straws to pass through is provided on the first end 13, and the outlet 131 is opposite to the transition space 101. The driving mechanism 30 includes a power source and a connecting rod 32 mechanism. The first end of the connecting rod 32 mechanism is drivingly connected to the power source. The second end of the connecting rod 32 mechanism passes through the second end 14 and extends into the storage space, and the second end of the connecting mechanism is arranged opposite to the transition space 101 to push the straws to be discharged out of the outlet 131 along the axial direction of the straws. The straw box device of the present invention has a simple structure and is convenient for picking up straws.

[0030] It should be noted that the straws to be discharged refer to the straws to be pushed out of the outlet 131 next time. For example, assuming that the straw box device can discharge 1 straw at a time, then the 1 straw about to be pushed out of the outlet 131 is the straw to be discharged. Of course, according to needs, the size of the outlet 131 can also be set larger to push out 2 straws at a time. In this embodiment, since the straws are pushed out along the axial direction of the straws, it is very convenient to pick up. In this way, it can be ensured that one or a small number of straws can be picked up in one operation, avoiding the disadvantages that many straws are stacked together in the prior art, which are easy to be contaminated and inconvenient to pick up.

[0031] It should be noted that the "first side wall 11" and the "second side wall 12" are only for the convenience of description to distinguish their names, and the names of the two can be swapped with each other. The first side wall 11 can be an integral structure or composed of multiple plates spliced together. The first side wall 11 can be a flat plate structure, an arc plate or other shapes. Similarly, the second side wall 12 can be an integral structure or composed of multiple plates spliced together. The second side wall 12 can be a flat plate structure, an arc plate or other shapes.

[0032] The "first end 13" and the "second end 14" are only for the convenience of description to distinguish their names, and the names of the two can be swapped with each other.

[0033] In the present invention, there is no particular limitation on the specific shapes of the "first end 13" and the "second end 14", which may be a flat plate, an arc or other shapes. The first end 13 may be an integral structure with the "first side wall 11" and the "second side wall 12", or a split structure connected together. The second end 14 may be an integral structure with the "first side wall 11" and the "second side wall 12", or a split structure connected together.

[0034] In order to facilitate the straws to gather downward in the container, the first side wall 11 can be set to be inclined alone, the second side wall 12 can be set to be inclined alone, or the first side wall 11 and the second side wall 12 can be set to be inclined at the same time. Figure 2 In this embodiment, the first side wall 11 is arranged to be inclined.

[0035] The first side wall 11 has an opening, and a panel 111 is provided at the opening. The panel 111 covers the opening, and the upper end of the panel 111 is rotatably connected to the inner side of the first side wall 11, that is, when the outer side of the panel 111 is pushed, the panel 111 can be pushed up.

[0036] The driving mechanism 30 is disposed outside the second end portion 14. The connecting rod 32 mechanism includes a rotating disk 31, a connecting rod 32, and a straw punch. The rotating disk 31 is connected to the power source for driving, and the power source drives the rotating disk 31 to rotate. One end of the connecting rod 32 is connected to the rotating disk 31 for eccentric rotation. That is, one end of the connecting rod 32 ( Figure 1 The left end in the figure) is connected to the disk surface of the rotating disk 31 through a rotating shaft and avoids the rotation center (i.e., the eccentric position) of the rotating disk 31, and the length direction of the connecting rod 32 is approximately perpendicular to the rotating shaft, so that the rotation of the rotating disk 31 can be converted into the translational motion of the connecting rod 32, and the other end of the connecting rod 32 is rotatably connected to one end of the straw punch 33, and the other end of the straw punch 33 passes through the second end portion 14 and extends into the transition space 101, and the straw punch 33 can be moved along the axial direction of the straw ( Figure 1 left and right directions).

[0037] It should be noted that the rotating disk 31 may be a circular disk structure or a cam structure shape.

[0038] Since the connecting rod 32 is eccentrically connected to the rotating disk 31, when the rotating disk 31 rotates, the rotating motion of the rotating disk 31 drives the connecting rod 32 to follow the motion, and the connecting rod 32 drives the straw punch 33 to move left and right. Figure 1Taking the state shown and the counterclockwise rotation of the rotary disk 31 as an example, when the rotary disk 31 rotates counterclockwise, the connecting rod 32 drives the straw punch 33 to move to the right. When the rotary disk 31 rotates counterclockwise by a certain angle (less than 90 degrees) such that the connection point of the connecting rod 32 and the rotary disk 31 is at the rightmost position, the straw punch 33 pushes the straw to be discharged out of the discharge port 131. Thereafter, the rotary disk 31 continues to rotate counterclockwise, and the connecting rod 32 drives the straw punch 33 to move to the left. When the straw punch 33 moves to a certain position, the next straw falls into the transition space 101 and waits to be pushed out of the discharge port 131 next time.

[0039] Further, the straw box device further includes a controller and a microswitch 60. The controller is signal-connected to the microswitch 60 and the power source. The microswitch 60 has a micro-touch rod 601. An extension 311 is provided on the outer edge of the rotary disk 31. When the rotary disk 31 rotates to a preset position (such as Figure 1 above in ), the extension 311 touches the micro-touch rod 601, and the microswitch 60 sends a signal to the controller. The controller controls the power source to stop moving according to this signal. In this embodiment, the power source is a motor.

[0040] The straw box device includes a material-dispensing mechanism 40, which includes a cam plate 41, a connecting rod 42, and a lifting unit. The cam plate 41 is rotatably connected to the power source. In this embodiment, the cam plate 41 and the rotating plate 31 are coaxially connected to the power source, that is, the power source drives the cam plate 41 to rotate together with the rotating plate 31. One end of the connecting rod 42 is in contact with the rim of the cam plate 41, and the other end of the connecting rod 42 passes through the second end plate. The lifting unit is located below the panel 111, and includes a mounting portion 431, a contact portion, and a lifting portion 433. The mounting portion 431 is rotatably connected to the outer side of the first side wall 11, and the contact portion is fixedly connected to the mounting portion 431. The contact portion has a contact slope 432 that contacts the end of the connecting rod 42. The contact slope 432 has an acute angle with the axial direction of the connecting rod 42, and the position of the contact slope 432 on the side close to the second end 14 is higher than the position on the side away from the second end 14. The bottom end of the lifting portion 433 is fixedly connected to the contact slope 432, and the top end of the lifting portion 433 keeps in contact with the outer side of the panel 111. In this way, when the connecting rod 42 moves to the left under the drive of the cam plate 41, the connecting rod 42 lifts the contact slope 432, thereby causing the lifting portion 433 to lift the panel 111 upward. The panel 111 is pushed upward to loosen the straws stored in the accommodation space, thereby preventing the straws stored in the accommodation space from being closely aligned and unable to fall into the transition space 101 .

[0041] Of course, in order to facilitate the installation of the driving mechanism 30, the straw box device includes a mounting base 20, and the mounting base 20 is fixedly connected to the second end 14. The driving mechanism 30, the material dispensing mechanism 40, the micro switch 60 and the power source can all be installed on the mounting base 20.

[0042] Furthermore, the toggle mechanism further includes a limit portion 45, the limit portion 45 is mounted on the mounting base 20, the limit portion 45 includes an avoidance notch, the connecting rod 42 is inserted into the avoidance notch, so that the connecting rod 42 cannot move up and down, but can only move along its axial direction ( Figure 1 At the same time, the limiting portion 45 also plays a role of installing and supporting the connecting rod 42.

[0043] In order to reduce the friction between the connecting rod 42 and the contact inclined surface 432, a roller is provided at the end of the connecting rod 42, so that the movement between the end of the connecting rod 42 and the contact inclined surface 432 becomes rolling friction, which greatly reduces the friction force and increases the movement smoothness of the material dispensing mechanism 40.

[0044] Further, the material pushing mechanism 40 further includes a return spring 44. One end of the return spring 44 is connected to the second end portion 14, and the other end of the return spring 44 is connected to the end portion of the connecting rod 42 on the side close to the lifting unit. Thus, when the connecting rod 42 moves leftward to the extreme position under the action of the cam disk 41, the return spring 44 is subjected to a tensile stress. Subsequently, the cam disk 41 loses its acting force on the connecting rod 42, and the connecting rod 42 moves rightward under the action of the return spring 44 to keep in contact with the rim of the cam disk 41.

[0045] The straw box device includes an empty tube detection switch 62, a tube outlet detection switch 64, and a display board (not shown in the figure). The empty tube detection switch 62 is disposed on the first side wall 11 or the second side wall 12. In this embodiment, the empty tube detection switch 62 is disposed on the second side wall 12. When there is no straw in the accommodation space, the empty tube detection switch 62 sends an empty material signal to the controller, and the controller issues an empty material warning message. The display board is provided with a display structure capable of displaying the empty material warning message, such as a colored signal lamp, or a buzzer capable of emitting a sound, etc. The tube outlet detection switch 64 is disposed at a position close to the discharge port 131 for detecting whether a straw is pushed out of the discharge port 131. When no straw is pushed out of the discharge port 131, the tube outlet detection switch 64 sends an empty tube signal to the controller, and the controller issues an empty tube signal. The display board is provided with an empty tube signal warning structure, such as a colored signal lamp, or a buzzer capable of emitting a sound, etc.

[0046] It should be noted that the controller of the present invention can be integrated in the display board. The display board can be disposed on one side of the first end portion 13.

[0047] The working principle of the straw box device in this embodiment is as follows:

[0048] When the straw box device is on standby, the protruding part 311 remains in contact with the microswitch 60; when straw discharging is required, the power source starts to drive the rotating disk 31 and the cam disk 41 to rotate. The rotating disk 31 rotates counterclockwise. After the connection point of the connecting rod 32 and the rotating disk 31 passes the lowest point below, the connecting rod 32 moves to the right, driving the straw punching rod to translate to the right. When the connection point of the connecting rod 32 and the rotating disk 31 is near the rightmost vertex, the straw punching rod pushes the straw with the discharging opening out of the discharging port 131; the rotating disk 31 continues to rotate counterclockwise, and the connecting rod 32 starts to move to the left, driving the straw punching rod to move to the left. When the straw punching rod moves to a certain position to the left, the next straw with the discharging opening falls into the transition space 101. When the rotating disk 31 rotates to the protruding part 311 in contact with the microswitch 60, the microswitch sends a signal to the controller, and the controller controls the power source to stop moving, and the rotating disk 31 also stops moving accordingly. That is, for each discharging, the rotating disk 31 stops after rotating one week.

[0049] Similarly, when the cam disk 41 rotates, the cam disk 41 can convert its circular motion into the axial motion of the connecting rod 42, and the connecting rod 42 moves to the left in Figure 2 the left direction, and the lifting part 433 moves upward under the action of the connecting rod 42 and the contact inclined surface 432, thereby lifting the panel 111 upward (i.e., into the accommodating space), and loosening the straws stored in the accommodating space.

[0050] It should be noted that the straw box device of the present invention can be used alone or in cooperation with machinery, such as being integrated with a vending machine, so as to make the sale and use of beverages more convenient.

[0051] The above has described in detail a preferred embodiment of the present invention in conjunction with the drawings. However, it is not limited to the specific details in the above embodiment. Within the technical concept scope of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
