Abstract

The utility model provides a gas projector for colorful fireworks, which comprises a colorful firework drum and an air storage bottle, wherein substances for forming colorful fireworks are arranged in the colorful firework drum, and compressed air is filled in the air storage bottle which is only provided with one air inlet and outlet hole. Thus, the utility model has the advantages of simple structure, low cost, long preservation period, tight sealing, safe use and no pollution to the air, and no matter in a room or outside a room, the utility model can be used.

Description

Firework gas transmitter

The utility model relates to a kind of firework transmitter, particularly a kind of firework gas transmitter.

When carrying out celebration activity, Chinese get used to setting off celebrating atmosphere by contrast by the firecracker of setting off fireworks.But firecracker has bigger danger owing to set off fireworks, and has both damaged health easily, causes fire again easily, and this mode is forbidden in some big and medium-sized cities of China.Like this, people just need a kind of product that can substitute fireworks and firecrackers.

The patent No. is that the Chinese utility model patent of ZL98209379.9 discloses a kind of firework transmitter, and it can be transmitted into sky to various colour bars, color sheet etc., forms multicoloured firework, thereby increases celebrating atmosphere.Though this product security greatly improves, because it still adopts the gunpowder emission, thus also have certain danger, but also can cause air pollution, be not suitable in indoor use.

The patent No. is that the Chinese utility model patent of ZL98232161.9 discloses another kind of firework transmitter, it adopts compressed air emission firework, thereby increased substantially security, and can not cause air pollution, all can relievedly use indoor or outdoor.The caisson of this transmitter has two air inlet/outlets, and promptly bottom is an air admission hole, and last cross is venthole, so there is deficiency in it on air-tightness, and the holding time is not very long, and complex structure, the cost height.

The purpose of this utility model is: provide a kind of air-tightness good, the holding time is long, firework gas transmitter simple in structure.

Above-mentioned purpose is achieved by the following technical solution: a kind of firework gas transmitter, contain a firework tube and a gas bomb, firework is housed in the firework tube forms thing, compressed air is housed in the gas bomb, the bottle mouth position of gas bomb has a pair of " L " shape bayonet socket, a compressing tablet snaps in described " L " shape bayonet socket bottom and pushes down sealing-plug, leaves an air-filled pore on compressing tablet; There is one can stir the tubular shifting part that described compressing tablet rotates in described bottleneck outside; The described firework tube of the outer connection of described tubular shifting part.

In such scheme, compressing tablet and tubular shifting part can be following structure: the middle part of described compressing tablet is circular, and respectively there is an ear on both sides, and stretch out from described " L " shape bayonet socket bottom the end of ear; Described air-filled pore is positioned at the center of compressing tablet; The both sides of the end of each ear respectively have one to dial bar longitudinally, and described group of bar overturn in tube by the middle part of the sidewall of described tubular shifting part and form.

As the improvement of such scheme, an ear of compressing tablet can be connected with the inwall of described firework tube by an elasticity connection cord.

When using this transmitter, described firework tube and gas bomb are relatively rotated, then described group bar is stirred described compressing tablet and is rotated, arrive the vertical component of " L " shape bayonet socket, compressing tablet top loses pressure suddenly, then in gas bomb under the compressed-air actuated effect, the firework in sealing-plug, compressing tablet and the firework tube forms the thing ejection.Firework forms thing and forms multicoloured effect aloft.Air-filled pore on the compressing tablet charges into the air of suitable pressure in gas bomb when supplying to produce, described thus gas bomb is only established an air inlet/outlet, thereby simplifies the structure, and has reduced cost.Because this gas bomb has only an air inlet/outlet, then makes sealing more tight, the holding time is longer.The elasticity connection cord that connects compressing tablet ear and firework tube can retract the compressing tablet that ejects, in case the thing of hurting sb.'s feelings, and recyclable utilization again.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 8 is the schematic diagram of the colored scraps of paper of pentalpha in the utility model firework gas transmitter;

Fig. 9 is the schematic diagram of the quincunx colored scraps of paper in the utility model firework gas transmitter;

Figure 10 is the schematic diagram of colorful film parachute in the utility model firework gas transmitter.

As shown in Figure 1 and Figure 2, the utility model firework gas transmitter contains a firework tube 1 and a gas bomb 2, firework is housed in the firework tube 1 forms thing 11, in the gas bomb 2 compressed air is housed, and a decorative sleeve 8 is arranged outside gas bomb 2.

The bottle mouth position of gas bomb 2 has a pair of " L " shape bayonet socket 21, the concrete shape of this bayonet socket as can be seen from Figure 3.A compressing tablet 3 snaps in described " L " shape bayonet socket 21 bottoms and pushes down sealing-plug 4, the middle part 31 of compressing tablet 3 is circular, respectively there is an

ear

32,33 on both sides, and stretch out from described " L " shape bayonet socket 21 bottoms the end of

ear

32,33, leaves an air-filled pore 34 at the center of compressing tablet 3; Referring to Fig. 4, there is one can stir the tubular shifting part 5 that described compressing tablet 3 rotates in described bottleneck outside; The both sides of the end of each ear respectively have one to dial bar 51 longitudinally, and described group of bar 51 overturn in tube by the middle part of the sidewall of described tubular shifting part 5 and form.The described firework tube 1 of described tubular shifting part 5 outer connections.In the ear 32 of compressing tablet 3 connecting hole 35 is arranged, elasticity connection cord 6 one ends are connected with compressing tablet 3 by connecting hole 35, and the other end is clipped between tubular shifting part 5 and the firework tube 1.

Firework formation thing 11 can be loaded as required in the firework tube 1, commonly used is the colored scraps of paper, chromatics paper ring and firework volume, wherein firework volume can be for as Fig. 5 or colored plastic web paper shown in Figure 6, after this kind plastic web paper is aloft opened, its limit is a zigzag, more more novel than general firework moulding, also can be colored plastic web paper as shown in Figure 7, it is opened the back and is continuous flag-shaped; The colored scraps of paper can for as Fig. 8, pentalpha shown in Figure 9 or quincunx, also can be dove shape, heart, lucky font, good fortune font, like font etc.Also can load colorful film parachute as shown in figure 10 in the firework tube simultaneously, this parachute is made up of canopy 74, umbrella rope 73, umbrella bob 72, vertically hung scroll 71, rope 75 and secondary bob 76.Wherein the weight ratio of canopy and umbrella bob is roughly 5: 7, and secondary effect of weighing down is to make canopy to open fully.

Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also carry out some kinds to this device and improve or modification, these improvement or modification all should be considered as belonging to protection domain of the present utility model.
