DETAILED DESCRIPTION

[0033] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Please refer to Figures 1 to 11 A bubble bullet feeding structure 4 includes: a middle sleeve 47; a magazine 46 connected to the middle sleeve 47; an outer shell 41, which is sleeved outside the middle sleeve 47 and threadedly connected thereto, and the outer shell 41 is provided with a delivery port 411 corresponding to the open end of the magazine 46; and a pressing piece 43, which is distributed between the delivery port 411 and the open end of the magazine 46, and the pressing piece 43 is configured to be able to close or open the magazine 46 as the outer shell 41 rotates relative to the middle sleeve 47, and to be able to approach or move away from the open end of the magazine 46 along the axial direction of the middle sleeve 47 as the outer shell 41 rotates relative to the middle sleeve 47. Specifically, as Figure 3 、 Figure 4 、 Figure 6 and Figure 8 As shown, an external thread 473 is provided on the outer wall of the middle sleeve 47 , and a first internal thread 414 is provided on the inner wall of the outer shell 41 . The first internal thread 414 is adapted to and threadedly connected with the external thread 473 .

[0037] During use, the outer shell 41 is first rotated so that it rotates relative to the middle sleeve 47 through the first internal thread 414 and the external thread 473 and simultaneously moves axially along the middle sleeve 47. During this process, the pressing plate 43 rotates with the outer shell 41 to open the open end of the magazine 46. Next, the bubble bomb 3 is loaded into the magazine 46 through the delivery port 411. The outer shell 41 is then rotated in the opposite direction, at which time the pressing plate 43 rotates with the outer shell 41 to close the magazine 46. Finally, the outer shell 41 is rotated in the same direction so that the pressing plate 43 moves axially along the middle sleeve 47 with the outer shell 41, thereby applying pressure to the bubble bomb 3 at the open end of the magazine 46, driving the bubble bomb 3 to be completely loaded into the magazine 46 until the bubble bomb 3 is punctured by the needle 2 disposed at the bottom of the magazine 46. When the gas inside the bubble bomb 3 is completely released, the outer shell 41 is rotated so that the pressing plate 43 opens the magazine 46, and the used bubble bomb 3 can be removed from the magazine 46 through the delivery port 411.

[0038] The bubble bullet feeding structure 4 here facilitates the disassembly and assembly of the bubble bullet 3, and can quickly lock and fix the bubble bullet 3 loaded into the magazine 46 through the pressing piece 43 and apply pressure to it to cooperate with the pricking needle 2 to release gas. During this process, the bubble bullet 3 is quickly disassembled and used by rotating the outer shell 41 and cooperating with the pressing piece 43. The structure is simple and easy to operate. Through the threaded transmission of the outer shell 41 and the middle sleeve 47, the process of the bubble bullet 3 being punctured by the pricking needle 2 is time-saving and labor-saving, and has strong practicality.

[0039] In this embodiment, when the outer shell 41 and the middle sleeve 47 are assembled, the insertion port 411 is coaxial with the magazine 46. The pressing piece 43 is located between the insertion port 411 and the opening of the magazine 46, thereby closing the magazine 46 by blocking the magazine 46 and / or the insertion port 411. When the pressing piece 43 is offset from the magazine 46 and / or the insertion port 411, the magazine 46 can be opened.

[0040] In this embodiment, in order to install the pressing piece 43, as shown in FIG. Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, it also includes a movable bracket 42 arranged between the outer shell 41 and the middle sleeve 47; one end of the movable bracket 42 slides against the outer shell 41, and the other end slides to the middle sleeve 47; the pressing piece 43 is installed on the movable bracket 42; the outer shell 41 acts on the movable bracket 42 so that it can move toward the magazine 46 in a manner of sliding along the axial direction of the middle sleeve 47. The connection parts between the middle sleeve 47 and the movable bracket 42 here are both cylindrical. In this embodiment, the lower end of the movable bracket 42 is slidably embedded in the upper end of the middle sleeve 47, and the movable bracket 42 can slide along the axial direction of the middle sleeve 47. Further, as Figure 8 As shown, the top inner side of the housing 41 is provided with a slip ring 412, which is arranged around the outside of the delivery port 411. Figure 3 As shown, the slip ring 412 slides against the upper end surface of the movable bracket 42, so that when the outer shell 41 and the middle sleeve 47 are threaded together, the outer shell 41 can apply pressure to the movable bracket 42 along the axial direction of the middle sleeve 47, thereby causing the movable bracket 42 to drive the pressing plate 43 to move axially along the middle sleeve 47 to approach the magazine 46. Here, the slip ring 412 can reduce the contact area between the outer shell 41 and the movable bracket 42 while applying force to the movable bracket 42, helping to reduce friction between the outer shell 41 and the movable bracket 42 and facilitate operation.

[0041] Furthermore, the movable bracket 42 is provided with a clearance hole 429 corresponding to the open end of the magazine 46. The pressing piece 43 is rotatably mounted to the movable bracket 42 and is located above the clearance hole 429. The pressing piece 43 includes an extension portion 432 and a rotating portion connected to each other. The rotating portion includes a rotating disk 431 rotatably connected to the movable bracket 42, and the rotating disk 431 is provided with a plurality of external teeth 434 along its circumference. The inner wall of the outer shell 41 is provided with internal teeth 413 that mesh with the plurality of external teeth 434. When the outer shell 41 rotates about the middle sleeve 47, the internal teeth 413 act on the external teeth 434 to cause the extension portion 432 to rotate about the rotating axis of the rotating disk 431 to close or open the clearance hole 429. When the extension portion 432 closes or opens the clearance hole 429, the internal teeth 413 disengage from the external teeth 434. Preferably, the rotating disk 431, the extension portion 432, and the external teeth 434 are integrally formed. The rotating disk 431 is provided with a shaft hole 433 therethrough.

[0042] The clearance hole 429 is used to connect the delivery port 411 with the opening end of the magazine 46. When in use, the bubble bomb 3 enters the magazine 46 from the delivery port 411 through the clearance hole 429. Figure 4 、 Figure 7 、 Figure 9 and Figure 11As shown, a turntable 424 is provided around the clearance hole 429, and a positioning hole 4241 is provided on the upper end surface of the turntable 424 in a manner extending axially along the movable bracket 42. During use, the turntable 431 slides and fits against the upper end surface of the turntable 424, and the pin 49 passes through both the shaft hole 433 and the positioning hole 4241. The pin 49 is fixedly connected to the turntable 424 through the positioning hole 4241, and is rotationally connected to the turntable 431 through the shaft hole 433. The turntable 431, i.e., the pressing plate 43, can rotate around the pin 49 to block or stagger the clearance hole 429, thereby closing or opening the clearance hole 429. Preferably, the turntable 424 is integrally formed with the movable bracket 42.

[0043] In this embodiment, Figure 8 、 Figure 9 and Figure 10 As shown, during the rotation of the housing 41, when the inner teeth 413 approach and mesh with the outer teeth 434, as the housing 41 continues to rotate, the inner teeth 413 rotate about the axis of the middle sleeve 47, thereby driving the rotating disk 431 where the outer teeth 434 are located to rotate about the pin 49. In this embodiment, to ensure that the outer teeth 434 fully mesh with the inner teeth 413, the tooth width of the inner teeth 413 is greater than the tooth width of the outer teeth 434.

[0044] Furthermore, the movable bracket 42 is configured with a first limit block 425 and a second limit block 426, and an extension portion 432 is located between the first limit block 425 and the second limit block 426. When the extension portion 432 abuts the first limit block 425, the extension portion 432 closes the clearance hole 429; when the extension portion 432 abuts the second limit block 426, the extension portion 432 opens the clearance hole 429. The first limit block 425 and the second limit block 426 are both capable of positioning the extension portion 432. In this embodiment, the first limit block 425 and the second limit block 426 are located around the clearance hole 429, and the turntable 424 is located between the first limit block 425 and the second limit block 426. During use, the inner teeth 413 drive the outer teeth 434 to make the turntable 431, i.e. the pressing plate 43, rotate between the first limit block 425 and the second limit block 426. When the pressing plate 43, i.e. the extension portion 432, abuts against the first limit block 425 or the second limit block 426, the pressing plate 43, i.e. the extension portion 432, reaches the extreme position. At this time, the outer teeth 434 disengage from the inner teeth 413, i.e. when the outer shell 41 continues to rotate, the pressing plate 43 no longer rotates with the outer shell 41.

[0045] In this embodiment, a first slot 4251 is provided on the first limit block 425, and a second slot 4261 is provided on the second limit block 426. Magnets 428 are embedded in both the first slot 4251 and the second slot 4261. Correspondingly, the pressing plate 43, or at least the extension portion 432 of the pressing plate 43, is made of iron, so that it can be attracted and fixed by the magnet 428 when it approaches or abuts against the first limit block 425 and the second limit block 426. When the extension portion 432 is not abutted against the first limit block 425 and the second limit block 426, and the inner teeth 413 and the outer teeth 434 are disengaged, the magnet 428 can magnetically attract the extension portion 432 so that the pressing plate 43 is quickly reset to accurately reach its limit position.

[0046] Furthermore, a baffle 427 is disposed between the first limit block 425 and the second limit block 426. The baffle 427 is disposed opposite to the turntable 424. When the pressing piece 43 is mounted on the turntable 424, the extension portion 432 is located on the lower side of the baffle 427 and slides in contact with the lower side of the baffle 427. Figure 11 As shown, the pressing plate 43 after installation has a cantilever structure, and the baffle 427 can support and limit the extension portion 432, so that its structure is stable when it is subjected to the reaction force of the bubble bomb 3, that is, when the shell 41 rotates, the pressing plate 43 can evenly apply pressure to the bubble bomb 3, and the driving effect is good.

[0047] Furthermore, if Figure 6 and Figure 7 As shown, a guide groove 472 is defined on the inner wall of the middle sleeve 47, and a guide block 423 is disposed on the outer wall of the movable bracket 42, adapted to fit within the guide groove 472. The guide block 423 slides within the guide groove 472. The guide groove 472 extends parallel to the axial direction of the middle sleeve 47. During use, the guide block 423 cooperates with the guide groove 472 to define the movement path of the movable bracket 42 relative to the middle sleeve 47. This prevents the movable bracket 42 from rotating with the outer shell 41 under the action of the slip ring 412, thereby ensuring a stable and reliable structure for the bubble bomb feed structure 4.

[0048] In order to limit the range of movement of the movable bracket 42 relative to the middle sleeve 47 and also to prevent the movable bracket 42 from being separated from the middle sleeve 47, in this embodiment, Figure 6 and Figure 7As shown, the movable bracket 42 is provided with a first clamping block 422, and the middle sleeve 47 is provided with a limiting clamping slot 471. The first clamping block 422 is slidably embedded in the limiting clamping slot 471. Specifically, the sidewall of the movable bracket 42 is provided with a notch, which is located at the lower end of the movable bracket 42. An elastic piece 421 is disposed within the notch. The first clamping block 422 is disposed at the lower end of the elastic piece 421. When the first clamping block 422 is subjected to a force in the radial direction of the movable bracket 42, the elastic piece 421 bends, allowing the first clamping block 422 to move in the radial direction of the movable bracket 42. When the external force is removed, the first clamping block 422 can be reset under the action of the elastic piece 421. Here, the limiting clamping slot 471 corresponds to the guide slot 472, and the guide block 423 corresponds to the first clamping block 422. During use, the lower end of the movable bracket 42 is embedded in the upper end of the middle sleeve 47, the guide block 423 is slidably embedded in the guide groove 472, and the first clamping block 422 is embedded in the limiting clamping groove 471. When the movable bracket 42 slides in the middle sleeve 47, the length of its movement is the axial length of the limiting clamping groove 471 in the middle sleeve 47.

[0049] In this embodiment, a reset member 44 is pressed between the movable bracket 42 and the middle sleeve 47; the reset member 44 acts on the movable bracket 42 to cause it to abut against the outer shell 41. During use, after the bubble bomb 3 is punctured by the needle 2 and deflated, it is necessary to reverse the rotation to remove the used bubble bomb 3. At this point, the pressure exerted by the outer shell 41 on the movable bracket 42 disappears, and the reset member 44 acts on the movable bracket 42, causing it to automatically reset along the axial movement of the outer shell 41 along the middle sleeve 47, thereby maintaining the relative position of the outer teeth 434 and the inner teeth 413, facilitating their engagement. Preferably, the reset member 44 is a spring.

[0050] Specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, the magazine 46 is equipped with a radially extending fixed disk 461. An extension protrusion 462 is provided on the outer edge of the fixed disk 461. A first stop protrusion 463 is provided on the extension protrusion 462. The inner wall of the middle sleeve 47 is equipped with a second internal thread 4741, a second stop protrusion 475, and a stop ring protrusion 474. The second internal thread 4741 is located near the lower end of the middle sleeve 47, the second stop protrusion 475 is located near the upper end of the middle sleeve 47, and the stop ring protrusion 474 is located between the second stop protrusion 475 and the second internal thread 4741.

[0051] When in use, the magazine 46 is embedded in the middle sleeve 47 , and the extended protrusion 462 is distributed between the second limiting protrusion 475 and the limiting ring protrusion 474 , so that the magazine 46 is axially limited and installed in the middle sleeve 47 .

[0052] In this embodiment, a plurality of extension protrusions 462 are provided at intervals, and a plurality of second limiting protrusions 475 are provided at intervals and are distributed one-to-one with the plurality of extension protrusions 462. During use, the magazine 46 is rotated so that the extension protrusions 462 and the second limiting protrusions 475 are staggered circumferentially. At this time, the magazine 46 is inserted into the middle sleeve 47 along the axial direction. When the extension protrusion 462 is between the second limiting protrusion 475 and the limiting ring protrusion 474, the magazine 46 is rotated circumferentially so that the extension protrusion 462 is engaged between the second limiting protrusion 475 and the limiting ring protrusion 474. At this time, the first limiting protrusion 463 cooperates with the second limiting protrusion 475 to prevent the magazine 46 from overrotating, thereby preventing the extension protrusion 462 from disengaging from the second limiting protrusion 475.

[0053] Furthermore, in order to facilitate the installation of the reset member 44, a fixing groove 464 is configured on the upper surface of the fixing plate 461. Figure 3 and Figure 4 As shown, the valve body 45 is assembled in the fixing groove 464, one end of the reset member 44 is connected to the valve body 45, and the other end is connected to the movable bracket 42. In this embodiment, as shown in FIG. Figure 3 As shown, the magazine 46 and the movable bracket 42 are both distributed in the middle sleeve 47 , and the movable bracket 42 is arranged on the upper side of the magazine 46 .

[0054] In order to prevent the outer shell 41 from being separated from the middle sleeve 47 during rotation, the present embodiment further includes a pull ring 48, which is detachably connected to the outer shell 41. Figure 3 、 Figure 8 and Figure 10 As shown, the inner wall of the housing 41 is provided with a third card slot 415, and the third card slot 415 is distributed near the lower end of the housing 41; the pull ring 48 is provided with a second card block 481 that cooperates with the third card slot 415. When in use, after the housing 41 and the pull ring 48 are assembled, the second card block 481 is engaged with the corresponding third card slot 415. Figure 3 As shown, the pull ring 48 is sleeved on the outer sleeve 47, and its inner diameter is smaller than the outer diameter of the external thread 473. The pull ring 48 is distributed on the lower side of the external thread 473 to prevent the housing 41 from being separated from the middle sleeve 47 due to over-rotation from the upper side of the external thread 473.

[0055] In this embodiment, the number of the third card slots 415 and the number of the second card blocks 481 are the same, that is, four.

[0056] Furthermore, if Figure 6As shown, a first stopper 476 is disposed on the outer wall of the middle sleeve 47, and a second stopper (not shown) that cooperates with the first stopper 476 is disposed on the inner wall of the outer shell 41. The second stopper can abut against or disengage from the first stopper 476 by rotating the outer shell 41 around the central axis of the middle sleeve 47. During use, the first stopper 476 cooperates with the second stopper to limit the rotation angle of the outer shell 41, preventing it from overrotating. It should be noted that the first stopper 476 cooperates with the second stopper so that the rotation angle of the outer shell 41 is less than one circle.
