Description

Festival string

The utility model relates to an entertainment article for various festive occasions and festivals.

The utility model relates to an improvement of a festival string. The festival string (patent application number 96216266.3) is used as a substitute of the traditional firecrackers, and has the advantage of no harm of flammability and explosiveness of the traditional firecrackers. However, the design of the festival string is still imperfect, mainly: the sounding membrane is in a closed state in the wedding cylinder, so that the sounding is not loud enough; in addition, the method of generating gas is not ideal. In this design, there are two methods of generating gas: one method is to release liquefied gas, and the method has the disadvantages that the use of Freon liquefied gas is not beneficial to the large target of environmental protection, and other non-combustible, non-explosive and pollution-free liquefied gases (such as CO) are used₂、O₂Etc.), the container must withstand relatively high pressures, which can be difficult to implement. Another method of obtaining gas in this design is to subject a compound (e.g., potassium bicarbonate) to thermal decomposition, which has the major disadvantage of requiring a relatively large amount of raw materials to obtain sufficient heat to drive the decomposition of a sufficient amount of the compound. Further, since the starting of the joy sticks is sequentially transmitted from front to back, the sound density of the device in which the sound film is broken (i.e., the number of joy sticks per unit time) is low.

The utility model discloses the purpose is: the shortcomings of the festival string are improved so as to produce a better new product, the updated product has denser and louder sound, and the gas obtaining method is simpler and more convenient. The product can be pulled into a string and lifted like the traditional firecracker when in use, so that the firecracker is more suitable for the use habit of people.

In order to achieve the above purpose, the utility model adopts the following basic concept: firstly, the position of the sound membrane in a closed state in the original design is changed, namely, the sound membrane (3) is arranged on the outer side of one end of the wedding cylinder (11) and is communicated with the outside, so that when the sound membrane is burst by gas, the sound is louder; secondly, all the happiness cylinders in the original device share a total air source, and each happiness cylinder is provided with an independent air source. The basic structure is as follows: (as shown in figure 1 and figure 6) removing the original air tap on the wedding tube and additionally arranging an air hole (7) and a bottom hole (17), respectively placing two materials A and B participating in the reaction in a container a (15) and a container B (12), and controlling the meeting of the materials A and B by a push rod (14) and the like; the third step is that: all the wedding barrels are arranged in a box-shaped starting structure, the structure is composed of an upper cover (27) and a lower cover (25), and a bottom plate (29) of the lower cover is provided with a pressure rod (28). When the upper cover (27) is pressed down, the pressure lever (28) drives the push rods (14) in all the wedding barrels to move upwards relatively, so that all the wedding barrels move simultaneously, and the densest sound is obtained; fourthly, lugs (1) are manufactured on the side wall of the wedding tube (11), so that all the wedding tubes can be lifted into a string by one tube wire (30) to make a sound.

The main advantages of the device are that: the method can obtain the sound which is denser and louder than the festive string, the method for obtaining the gas is simpler and more convenient, the reliability of the whole system is higher, and the use of the system is more in line with the habits of people.

Six embodiments of the device are described below with reference to the drawings.

Fig. 6 is a schematic view showing the assembling position of the wedding cylinder (11) in the first to fifth embodiments. Fig. 7 is a schematic view of the liner frame (26). Fig. 8 is a schematic view of the wedding cylinder (11) in the lower cover (25) according to the first to the fifth embodiments. Fig. 9 is a schematic view (partially) showing the structure of a wedding cylinder (11) and its mounting position in the sixth embodiment. Figure 10 is a schematic view of the device when it is being sounded with the ornament (31).

A first embodiment is shown in figures 1, 6, 8 and 10. In this implementationIn the example, the material A is FeCl₃The material B is K₂CO₃Is a reaction of K₂CO₃Is placed in a container B (12), and FeCl is added₃Dissolving in dilute hydrochloric acid, and then adding FeCl₃The diluted hydrochloric acid solution (hereinafter referred to as solution A) of (1) is placed in a container a (15). The concentration of the dilute hydrochloric acid can be about 2 to 4 percent, and FeCl₃It should be sufficiently dissolved therein. In practical implementation, AlCl can also be used as the material A₃However, it is preferable to use a catalyst at the same time. In practice, the materials A and B can be selected from other materials.

As shown in figure 1, an absorbent body (9) is filled in the upper partition (10), and in this example, the material of the absorbent body is flexible foam. For preventing leakage, a partition layer (6) and a paper pad (8) can be added between the absorbent body (9) and the mascot (5), and the partition layer (6) can be made of disc-shaped flexible foam plastics. The paper pad (8) is composed of a plurality of layers of soft paper. The actions in the device are performed as follows: when all the pressing rods (28) on the bottom plate (29) of the lower cover (25) push the lower pistons (16) in all the wedding cylinders (11) with the same number of pressing rods upwards so that the middle piston (13) enters the container B (12), the solution A and the solution B meet immediately and generate gas, and the chemical reaction formula is as follows:

the gas bursts the acoustic membrane (3) through the gasholes (7) and the like.

A second embodiment is shown in figure 2. It differs from the first embodiment in that: the middle piston (13), the lower piston (16) and the push rod (14) are replaced by a middle partition (18), a sealing ring (20) and a push rod (19). The side wall of the bottom hole (17) of the cartridge is slightly changed corresponding to the ejector rod (19). Alternatively, the middle piston (13) can be replaced by only a septum (18), which can be made of synthetic rubber completely or be attached with synthetic rubber only at the edge to facilitate sealing. When the septum (18) is made in the shape of a cone and B is placed in a particulate form, either the septum (6) or the paper pad (8), or both, may be omitted.

A third embodiment is shown in figure 3. In the figure, the container b (12) may be made wholly or partly of a soft material, and the soft material may be an elastic material such as a rubber film (as shown in fig. 3), or a plastic film, or an aluminum foil material. The air B (22) present in the container B (12) other than the solution B is preferably compressed air. The liquid filling method shown in the figure is as follows: a rubber plug (21) is embedded above the container b (12), and then the solution is injected by a needle. In this example, the container a (15) is a lower cavity of the cartridge (11), and the internal pressure thereof may be normal pressure. When the wedding cylinder (11) is forced to move downwards, the cutting body (24) punctures the container b (12) to cause a series of actions.

A fourth embodiment is shown in figure 4. This is a variation of the third embodiment, and in this case, both the air a (23) and the air b (22) are preferably compressed air. While the cutting edge portion of the cutting body (24) is double. In a fifth embodiment, as shown in fig. 5, the container a (15) and the container b (12) are both made of soft material, and the cutting edge of the cutter (21) can be a blade.

Other alternatives are also contemplated by the above embodiments. For example, in the first, second and third embodiments, the solution A in the container a (15) is replaced with the fine powder of B, while the solution B in the container B (12) is replaced with the solution A. In a fifth embodiment, the solution A can be replaced by the fine powder of A and the solution B can be replaced by the fine powder of B, and meanwhile, the lower cavity of the cartridge (11) is filled with a proper amount of purified water.

The cartridge of the device is typically tens of cartridges, and the first to fifth embodiments are assembled as shown in fig. 6. In the figure, the upper cover (27) and the lower cover (25) are clamped by a horseshoe-shaped lining frame (26), so that the upper cover cannot be pressed downwards. The shape of the liner frame is shown in fig. 7, and the width and the height of the liner frame are determined according to actual size requirements. (in practice, the lining frame (26) and the upper cover (27) and the lower cover (25) should be in proper movable fit). When in use, all the wedding barrels can be lifted by a stick and sounded only by taking off the lining frame (26), pressing down the upper cover (27) and taking off the lining frame immediately after the lining frame is in place (a handle is arranged above the upper cover (27) in actual production). (the situation that the wedding tube (11) is positioned in the lower cover (25) before being sounded is shown in figure 8, one end of the tube wire (30) is led out to be lifted on a stick, and the other end of the tube wire passes through the wire lugs (1) on the outer side of each wedding tube in sequence. Or, the tube wire (30) is provided with a hook structure, and the wire lugs (1) can be hung on the tube wire in sequence.)

What differs from the five embodiments described above is a sixth embodiment, as shown in fig. 9. At this time, the wedding cylinder (11) is in a closed state as a whole because no bottom hole is arranged, and is assembled in a square box consisting of an upper cover (27) and a lower cover (25) by using left and right symmetrical bolts (35) in the direction opposite to the directions of the five embodiments. When the bolt (35) is pulled out and the upper cover (27) is pressed down, the press rod (28) pushes the sounding film (3), the aerosol (4), the mascot (5), the adsorbent (9) (the absorbent paper ring at this time) and the like upwards together, so that the small end of the I-shaped rod (33) slides out of the rubber ring (32), and the solution A meets the material B through a hole in the middle of the rubber ring (32) to cause action. (the disc-shaped big head of the I-shaped rod (33) is provided with a material hole (34) for loading the material B). Thus, the sound film (3) is turned downward in this example. However, in normal times, the whole device (the wedding tube, the upper cover and the lower cover) should be stored upside down. In particular, it is also possible to overlap several devices one above the other and connect the bobbins, and to activate the sound emission in succession.

In order to make the product not only have entertainment but also have decorative effect, the ornament part is added in the device. As shown in fig. 9, a decoration (31) is attached to the upper end of the bobbin thread (30). The ornament (31) can be a three-dimensional character, such as a lucky word eye like 'xi', 'qing', '8', etc., or an article, such as a lucky article like dragon, phoenix, peach, etc. The ornament may be solid; it can also be made hollow and have a light system built in, which has a flashing lamp.

In addition, the outer surface of the wedding tube (11) (the outer surface is red generally) can be printed with golden characters such as 'happy', 'celebration', 'longevity','xi', etc., and can also be printed with various lucky patterns. Each product is preferably printed with only one character or pattern and matched with corresponding ornaments to suit different occasions (note: the diameter of the bottom surface of the wedding cylinder (11) and the height of the cylinder can be properly adjusted according to requirements, for example, the height of the cylinder can be changed between 50-150mm, even higher, and the diameter of the bottom surface of the cylinder can be properly selected.)

In order to increase the pleasure, when the wedding tube (11) is used singly or in a plurality of ways, the wedding tube can be changed into a hand-held form, and the wedding tube can be changed as follows: the lug is removed, the front end of the wedding cylinder (namely the part where the membrane ring (2) is positioned) is lengthened, a plug is added in front of the sound membrane (3), and the mascot (5) and the aerosol (4) are moved between the added plug and the sound membrane (3). Thus, when the snare membrane breaks, the added plug will be thrown out together with the mascot (5) and aerosol (4). The mascot can be a colored ribbon and is connected with the added plug, and a miniature whistle can be further connected with the mascot. Phosphorescent pigments may also be added to the mascot (5). The device thus modified, whose throwout has a certain impulse, must be strictly limited to adult use, or else it is preferable not to make this modification in order to avoid unpleasant consequences. Of course, the impact force of the throwing object can be adjusted to be smaller, a miniature whistle is not needed, but the throwing height is greatly reduced, so that the throwing object becomes another entertainment product.

In the above embodiments, the sound film (3) is located outside one end of the wedding tube (11) and can be fixed by the film ring (2). The sound membrane can be made of a rubber film or a piece of moistureproof paper, the thickness of the sound membrane can be selected from 0.05-0.2 mm according to factors such as product specifications, and other methods can be adopted for replacing the sound membrane without using a membrane ring.

In addition, an aerosol (4) can be added at the position of the mascot (5), and the aerosol can be fine powder prepared by drying plants and can be sprayed with spices.

In order to obtain a flashing effect while sounding, for use at night, a flashing light system may be incorporated in the device, the power (battery) switch of which is preferably designed to be switched on at the start of a sound. (for example, the connection of the battery switch may be interlocked with the pressing operation of the upper cover (27), and the time for starting the flashing of the circuit may be delayed as appropriate). The luminous bodies (such as light emitting diodes) can be arranged in a proper number in a plurality of empty cylinders with the shape similar to that of the wedding cylinder and are arranged in the whole string of products at intervals. The flash frequency may be appropriately selected. These are all established techniques and only need to be configured appropriately.

As the traditional firecrackers are gradually replaced by the device, the huge fire loss and damage accidents caused by the firecracker discharging can be reduced day by day.
