Embodiment Construction

[0045] according to Figure 1 to Figure 15 As shown, a kind of electronic fireworks bomb described in this embodiment includes a lower base 1 and a mounting plate 31 fixedly connected to the upper end of the lower base 1; the upper end of the mounting plate 31 is uniform along the circumferential direction of the mounting plate 31 A plurality of pressure-bearing cylinders 311 are formed; each of the pressure-bearing cylinders 311 is longitudinally sealed and slidably connected with an inner groove body 34 for pushing out the filler; There is a release drum 4 with a rotating shaft longitudinally arranged coaxially with the installation disc 31; the upper end of the release drum 4 is formed with a lower release groove 41 that allows only one inner tank body 34 to pass upward at the same time .

[0046] The inner bottom ends of each of the pressure-bearing cylinders 311 are respectively formed with a pressure port 3111; the inner bottom ends of each of the pressure-bearing cylin...

Abstract

The invention discloses an electronic display shell. The electronic display shell comprises a lower base and a mounting disc, and a pressure-bearing cylinder is formed on the mounting disc; an inner groove body is slidably connected into the pressure-bearing cylinder; the lower base is rotationally connected with a release rotary drum; a lower release groove is formed in the release rotary drum; a pressurizing opening is formed in the pressure-bearing cylinder; a sealing base is fixedly connected into the pressure-bearing cylinder; a sealing sliding groove is formed in the sealing base. a sealing plate is slidably connected into the sealing sliding groove; a pressurizing air cavity is formed in the mounting disc; an impeller is rotationally connected to the lower base; a pressure release valve is arranged below the mounting disc; an air pump is arranged on the lower base; when the pressure-bearing cylinder is communicated with the pressurizing air cavity, the air pump works to enable the inner groove body to abut against the inner top end of the release rotating cylinder; and when the pressure-bearing cylinder is not communicated with the pressurizing air cavity, the air pump works to push the inner groove body opposite to the lower release groove outwards. The electronic display shell is used as a firecracker; the detonation mode is safer and more reliable; environmental protection and energy conservation are better achieved, and meanwhile, most of the structures can be repeatedly utilized; and the simple structure and easy assembling are achieved.

Description

technical field [0001] The invention belongs to the technical field of fireworks cannons, and in particular relates to an electronic fireworks shell. Background technique [0002] The Chinese patent literature with the document number CN210645111U discloses that the utility model relates to the field of fireworks display, and specifically discloses a fireworks display power structure and an environment-friendly fireworks display with the structure. The fireworks display power structure includes a container with a built-in high-pressure gas The mouth of the container is provided with a flap hinged at one end to the mouth, the other end of the flip is fixed to the mouth of the container by a binding structure, the binding structure is in contact with a lead wire, and the binding structure is made of burnable material become. The detonation method of the power structure of the fireworks cannon is safe, environmentally friendly and economical, and the power structure of the fir...
