[0001] The utility model relates to the technical field of material injection, in particular to an ejection flower cavity. Background Art
[0002] In wedding ceremonies, opening ceremonies or other festive occasions, people use various ejection flower cavities to express blessings; compressed air is provided at the lower end of the middle part of the ejection flower cavity. During use, by rotating the tail of the ejection flower cavity to open the valve, the compressed air will quickly eject colored shredded paper strips, so as to achieve the purpose of adding color to the wedding activities.
[0003] Since the power of the ejection flower cavity is provided by compressed air, and the user cannot fill it by himself after the compressed air is released, this results in that the ejection flower cavity cannot be used for a second time, and a large number of cavities will be discarded after wedding ceremonies, opening ceremonies and other occasions, which not only causes trouble to the cleaning staff, but also causes waste of resources.
[0004] As can be seen from the above, the prior art obviously has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0026] Refer to Figure 1 , the present utility model provides an embodiment 1 of an ejection flower cavity here, including a cavity 1, an elastic member 2, an ejecta 3 and a drive rod 4; wherein, the elastic member 2 is arranged inside the cavity 1, and the ejecta 3 is placed inside the cavity 1; in addition, the drive rod 4 is rigid, and one end of the drive rod 4 is connected to the elastic member 2; thereby, when the present utility model is in use, the user pulls the drive rod 4 by hand, and after the drive rod 4 is stressed, it pulls the elastic member 2 to deform. When the user releases the drive rod 4, the force applied to the drive rod 4 is lost, and the resilience generated by the elastic member 2 acts on the ejecta 3, thereby pushing out the ejecta 3 inside the cavity 1; and the drive rod 4 is also affected by the resilience of the elastic member 2 and will push back the ejecta 3, so that the acting force of the elastic member 2 when ejecting the ejecta 3 is greater than the acting force of using the elastic member 2 alone, the ejecta 3 is ejected farther, and the ejection effect is better; and the ejection of the ejecta 3 does not rely on gas. After the first use, the ejecta 3 can be refilled into the cavity 1 and used again. It is easy to operate, meets the requirement of multiple uses, and reduces resource waste.
[0027] It should be noted that the elastic member 2 in Embodiment 1 is an elastic leather pad or an elastic rubber pad, and those skilled in the art can select other elastic members 2 according to the actual situation.
[0028] It should be noted that the ejecta 3 in Embodiment 1 are colored ribbons and colored paper pieces, and those skilled in the art can select other ejecta 3 according to the actual situation.
[0029] See Figure 2 、 Figure 3 Based on Embodiment 1, the present utility model proposes an Embodiment 2: In this Embodiment 2, the elastic member 2 is no longer connected to one end of the driving rod 4, but is connected to the middle section of the driving rod 4; in addition, a carrier plate 11 is provided in the cavity 1 between the ejecta 3 and the driving rod 4; the inside of the driving rod 4 is hollow and a first chute 41 is opened at two opposite positions on the inner side wall, and a first sliding rod 5 is provided inside the driving rod 4. A first sliding shaft 51 corresponding to the number and position of the first chute 41 is provided on the outer edge of one end of the first sliding rod 5; the inside of the first sliding rod 5 is hollow and two second sliding shafts 52 are oppositely arranged in the middle section of the inner side wall, and a second sliding rod 6 is provided inside the first sliding rod 5. A second chute 61 corresponding to the number and position of the second sliding shafts 52 is provided on the outer side wall of the second sliding rod 6;
[0030] Further, in the non-stretched state of the elastic member 2, the two end portions of the driving rod 4 are correspondingly marked as a static end point a and a static end point b, and convex rings 12 are wound around the inner side wall of the cavity 1 at positions corresponding to the static end point a and the static end point b; and the radial cross-section of the carrier plate 11 is larger than the inner diameter of the convex ring 12 and smaller than the outer diameter of the convex ring 12; thereby, this Embodiment 2 has two usage modes according to different ejecta 3:
[0031] One, place the end of the cavity 1 close to the static end point a upward, place the carrier plate 11 on the convex ring 12 at the static end point a, and then place the ejecta 3 on the carrier plate 11; at this time, the first sliding shaft 51 of the first sliding rod 5 is blocked by the first chute 41 and cannot extend out of the driving rod 4; and the second sliding rod 6 slides downward under the influence of natural gravity until the second chute 61 is stopped by the second sliding shafts 52, so that the end of the second sliding rod 6 exposes out of the cavity 1 for the user to pull; thereby, a relatively large loading space is formed above the carrier plate 11, and the distance from the carrier plate 11 to the end face of the cavity 1 is far; when the ejecta 3 are light objects such as colored ribbons and colored paper pieces, this method can carry more ejecta 3, with a better visual effect and more festive (but this method is not applicable to the case where the ejecta 3 are heavy objects such as coins and candies; because the distance from the carrier plate 11 to the end face of the cavity 1 is far, the resilience of the elastic member 2 may not be able to push objects such as coins and candies out of the deeper cavity 1).
[0032] II. Place the end of the cavity 1 close to the static end point b facing upwards, place the carrier plate 11 on the convex ring 12 at the static end point b, and then place the ejecta 3 on the carrier plate 11. At this time, affected by natural gravity, the first sliding rod 5 slides downwards along the first chute 41 with its first sliding shaft 51, and at the same time, the second sliding rod 6 also slides downwards under the influence of natural gravity until the second chute 61 is stopped by the second sliding shaft 52, so that the end of the second sliding rod 6 exposes out of the cavity 1 for the user to pull. Thus, a smaller loading space is formed above the carrier plate 11, and the distance from the carrier plate 11 to the end face of the cavity 1 is close. When the ejecta 3 is a heavy object such as a coin or a candy, this method can meet the short-distance ejection of the heavy ejecta 3 for sprinkling coins, wedding candies, etc. on festive occasions, with more uses (however, this method is not applicable to light ejecta such as ribbons and colored paper; because the loading space is small, the visual effect during ejection is not ideal).
[0033] It should be noted that the ejecta 3 of the present utility model is not limited to the coins, candies, ribbons, colored paper, etc. mentioned in Embodiment 1 and Embodiment 2, and those skilled in the art can select other ejecta 3 according to the actual situation.
[0034] It should be noted that both ends of the cavity 1 of the present utility model are sealed with fireworks paper at the factory.
[0035] In summary, the present utility model provides an ejection flower cavity. The ejecta is jointly pushed by the elastic member and the driving rod, so that the acting force of the elastic member when ejecting the ejecta is greater than the acting force of using the elastic member alone, the ejecta is ejected farther, and the ejection effect is better; and the ejection of the ejecta does not rely on gas. After the first use, the ejecta can be refilled into the cavity for reuse. It is easy to operate, meets the requirement of multiple uses, and reduces resource waste; by using the end of the cavity close to the static end point a facing upwards, a larger loading space is formed above the carrier plate, and the distance from the carrier plate to the end face of the cavity is far; when the ejecta is a light object such as a ribbon or colored paper, this method can carry more ejecta, with a better visual effect and more festive atmosphere; by using the end of the cavity close to the static end point b facing upwards, a smaller loading space is formed above the carrier plate, and the distance from the carrier plate to the end face of the cavity is close; when the ejecta is a heavy object such as a coin or a candy, this method can meet the short-distance ejection of the heavy ejecta for sprinkling coins, wedding candies, etc. on festive occasions, with more uses.
[0036] Of course, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
