Abstract
A kind of onboard charger; it is characterized in that: comprise charger body (1); with the internal circuit of charger body (1), described internal circuit comprises and connects relay (2) and current sensing means (3), described charger body (1) is provided with cigarette lighter plug (4); Described charger body (1) is provided with USB jack (5); Described charger body (1) is provided with anion generator (6).
Description
Technical field
The utility model relates to a kind of onboard charger.
Background technology
Along with the development of science and technology, various portable electronic apparatus (such as mobile phone, MP3, navigator) is more and more applied in daily life, and these electronic apparatuss need can charge easily in various occasion.Conveniently consumer gives the charging of various electronic apparatus when driving a vehicle, and just needs onboard charger.
The conventional onboard charger being used for automobile storage battery (car 12V, truck 24V) and powering, is used in the lithium cell charging field of various portable, portable equipment in a large number, such as: mobile phone, and PDA, GPS etc.; Car fills the actual demand (constant voltage CV, constant current CC, overvoltage protection OVP) should considering lithium cell charging, takes into account the adverse circumstances (transient peak voltage, system switching noise jamming, EMI etc.) of vehicular power-bottle again; Therefore the power management IC that car fills scheme selection must meet simultaneously: high pressure resistant, high efficiency, high reliability, the switching power source chip of low frequency (being conducive to the design of EMI); Existing product generally has overload protection; short-circuit protection; high input voltage is protected; high temperature protection; quadruple safety protection function, guarantees to use safely, but due to previous reasons; still can inevitably run into vehicle power instability at onboard charger, voltage exports the prominent height of peak value and burns out mobile phone.
In addition, conventional onboard charger function singleness, does not have air-cleaning function.
Summary of the invention
For solving the problem, the utility model proposes a kind of onboard charger.
The technical solution of the utility model is: a kind of onboard charger, comprises the internal circuit of charger body and charger body, and described internal circuit comprises relay and current sensing means; Described charger body is provided with cigarette lighter plug; Described charger body is provided with USB jack; Described charger body is provided with anion generator.
Low-voltage rises to as negative direct current high voltage by booster circuit by described anion generator, utilize the most advanced and sophisticated high direct voltage of carbon hairbrush to produce high corona, the electronics that releasing is at a high speed a large amount of, and electronics also cannot be present in air for a long time, can be caught by the oxygen molecule in air at once, form anion.Because anion mostly is oxonium ion and hydration hydroxyl ion etc., the little negative oxygen ion in air or be referred to as little negative oxygen ion group, has good biologically active, has good effect to health.Described anion generator is commercially available, and its structure and operation principle are known by technical staff, and correction here repeats.
Further, described internal circuit also comprises overload protecting circuit, short-circuit protection circuit, high input voltage protective circuit, high-temperature protection circuit.
The utility model compared with prior art, it has following beneficial effect: onboard charger of the present utility model, in use, not only there is overload protection, short-circuit protection, high input voltage is protected, high temperature protection, quadruple safety protection function, and on this basis, also add a heavy defencive function, when mobile phone is full of electricity, people usually can forget he is pulled out, and let alone continuation and insert power supply, as long as the time not longly can not damage mobile phone inside common such as household electrical source, but for the evil slightly environment of vehicular power-bottle, still power supply is pulled out as early as possible as well, the current sensing means of this utility model carries out detecting in time no current or Weak current being detected by being namely full of electricity to electric current, relay is deenergization just, protection mobile phone, avoid unnecessary injury.In addition, described charger body is provided with anion generator, low-voltage rises to as negative direct current high voltage by booster circuit by anion generator, the most advanced and sophisticated high direct voltage of carbon hairbrush is utilized to produce high corona, the electronics that releasing is at a high speed a large amount of, and electronics also cannot be present in air for a long time, can be caught at once by the oxygen molecule in air, form anion, have good effect to health.It also offers automatic circuit break function, have safe and reliable, protection mobile phone, the advantage of energy savings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is current detection circuit schematic diagram of the present utility model.
Fig. 3 is relay deenergizing schematic diagram of the present utility model.
Embodiment
Consult a kind of onboard charger of Fig. 1, Fig. 2 and Fig. 3, comprise the internal circuit of charger body 1 and charger body 1, described internal circuit comprises relay 2 and current sensing means 3, and described charger body 1 is provided with cigarette lighter plug 4; Described charger body 1 is provided with USB jack 5; Described charger body 1 is provided with anion generator 6.
Low-voltage rises to as negative direct current high voltage by booster circuit by described anion generator 6, utilize the most advanced and sophisticated high direct voltage of carbon hairbrush to produce high corona, the electronics that releasing is at a high speed a large amount of, and electronics also cannot be present in air for a long time, can be caught by the oxygen molecule in air at once, form anion.Because anion mostly is oxonium ion and hydration hydroxyl ion etc., the little negative oxygen ion in air or be referred to as little negative oxygen ion group, has good biologically active, has good effect to health.Described anion generator 6 is commercially available, and its structure and operation principle are known by technical staff, and correction here repeats.
Further, described internal circuit also comprises overload protecting circuit, short-circuit protection circuit, high input voltage protective circuit, high-temperature protection circuit.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept, the various modification that this area ordinary person makes the technical solution of the utility model and improvement, all should drop into protection range of the present utility model.
