As a further aspect of the present invention: the switch S1 is a tact switch.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses choose for use 30um 7v to become voltage or 40um 7v to become electric capacity at the in-process that discharges, because discharge current's reason can charge to the negative pole, consequently, select higher formation voltage, effectively prevent the damage of electric capacity heavy current discharge to the negative pole.
Drawings
Fig. 1 is a circuit diagram of the present design.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, embodiment 1: the embodiment of the utility model provides an in, a long-life flash light of utilization electric capacity, including power E, resistance R1, electric capacity C1, switch S1 and flash tube S, electric capacity C1 and flash tube S are connected to power E ' S positive pole, and electric capacity C1 and switch S1 are connected to power E ' S negative pole connecting resistance R1, resistance R1 ' S the other end, flash tube S ' S the other end is connected to switch S1 ' S the other end.
The power supply E charges the capacitor C1; after full charging, the switch S1 is closed, and the capacitor C1 discharges the triggered flash tube S, forming a cycle. The purpose of flashing is achieved.
Example 2: on the basis of embodiment 1, the electronic components adopted by the design are all of a patch type, and the electronic components are small in size, convenient to weld and high in integration level.
The flash lamp electric capacity negative pole paper tinsel of ordinary life generally chooses for use 20um 3V to become the specification of voltage, and the utility model discloses choose for use 30um 7V to become voltage or 40um 7V to become electric capacity at the in-process that discharges, because discharge current's reason, can charge to the negative pole, consequently, select higher formation voltage, effectively prevent the electric capacity heavy current to discharge the damage to the negative pole.
The common flash lamp capacitor generally adopts wood pulp paper as insulating paper, but the wood pulp paper has high density and large capacitance internal resistance, and the wood pulp and hemp pulp mixed electrolytic paper is adopted in the design to reduce the capacitance internal resistance, thereby reducing the heating value of the capacitor under the charging and discharging, and reducing the heat accumulation of the capacitor.
The negative foil of the capacitor of the common flash lamp is not connected with the shell, and the design adopts widening of the negative foil to make the negative foil level with electrolytic paper at the bottom of the aluminum shell of the capacitor, so that the negative foil is connected with the bottom of the aluminum shell, the heat dissipation performance of the capacitor is increased, the heat accumulation of the capacitor during charging and discharging is reduced, and the heat balance temperature is reduced.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
