Abstract
The utility model relates to a disposable electronic cigarette control circuit with a battery low-voltage alarm indication function. The disposable electronic cigarette control circuit with the battery low-voltage alarm indicating function comprises a control chip; the control chip is provided with an alarm end used for battery low-voltage alarm indication; and the alarm end is connected with an alarm lamp. The following two alarm methods are provided: 1) when an electronic cigarette works, instantaneous voltage when a sampling signal input end is disconnected is lower than a battery low voltage set value, the alarm end is energized, and the alarm lamp instantly flashes quickly to show warning; and 2), when the electronic cigarette does not work, input voltage of a power source access end is lower than the battery low voltage set value, the arm end is energized, and the alarm lamp quickly flashes at intervals to show warning. with the disposable electronic cigarette control circuit adopted, when the electronic cigarette is delivered out from a factory, when the control chip in a standby mode, and voltage is lower than a set value, the alarm lamp quickly flashes at intervals, and therefore, it is convenient for manufacturers, terminal sales and customers to know the electricity shortage situation of the electronic cigarette, and the manufacturers, terminal sales and customers can prevent defective products from flowing out to the market; and the customers can know the low-voltage condition of a battery in a use process by means of the arm function, so that the customers can have enough time to prepare to replacement the electronic cigarette .
Description
Technical field
The utility model relates to a kind of disposable electric cigarette, and specifically a kind of disposable electric smoking set has the control circuit of battery low pressure alarming instruction.
Background technology
Existing market segmentation has point chargeable and disposable two kinds of electronic cigarettes.Chargeable electronic cigarette cost is higher, can repeatedly discharge and recharge battery.Disposable electric cigarette cost is lower, as shown in Figure 1, the control circuit schematic diagram of disposable electric cigarette in conventional art, its control chip adopts application-specific integrated circuit, packing forms is SOT-23-6, and its LED foot control relay indicating light D processed, when consumer aspirates electronic cigarette, this lamp sends ruddiness, simulates smoke point and works sent out light.Disposable electric cigarette is battery full charging before dispatching from the factory, but due to the characteristic of self-discharge of battery, or terminal sale not in time, after a period of time, battery there will be low voltage, causes electronic cigarette can not aspirate or aspirate the situation that number of times is few, this situation is because producer and terminal sale personnel cannot predict, therefore client can return goods or complain, and causes client to reduce the purchase intention of this electronic cigarette, can further affect prestige, the shipment amount of producer when serious.When normal use, client cannot learn when battery electric quantity is used up, and is unfavorable for that client changes.
Therefore, require further improvement.
Utility model content
The purpose of this utility model aims to provide a kind of simplicity of design.Rational in infrastructure, can monitor cell voltage, and the disposable electric smoking set of the instruction of reporting to the police during lower than setting value at voltage has the control circuit of battery low pressure alarming instruction, to overcome weak point of the prior art.
There is the control circuit of battery low pressure alarming instruction by a kind of disposable electric smoking set of this object design, comprise control chip, control chip is provided with for the power access end of electric current access, for the sampled signal input end that is connected with physical switch, for exporting the work indication end that drives the output terminal of electronic cigarette heating wire working current, indicate for working and the earth terminal for control chip ground connection, its architectural feature is the warning end being also provided with on control chip for the instruction of battery low pressure alarming, and the end of reporting to the police is connected with alarm lamp.
Described battery low pressure setting value is 3.8V-4.0V.
Described power access end is connected with the positive pole of battery, and sampled signal input end SW is connected with inductive switch, and output terminal is connected with heating wire, and indication end is connected with portable lamp.
Disposable electric smoking set has an alarm method for the control circuit of battery low pressure alarming instruction, and it comprises the steps:
One, when electronic cigarette is worked, transient voltage when sampled signal input end disconnects is lower than battery low pressure setting value, and the end of reporting to the police is switched on, and the instant quick flashing of alarm lamp is to show warning.
Two,, when electronic cigarette inoperative, the input voltage of power access end is lower than battery low pressure setting value, the end energising of reporting to the police, and alarm lamp interval quick flashing is to show warning.
Described quick flashing number of times is 2-3 time, and be 1-2 hour described interval time.
The utlity model has following beneficial effect:
After disposable electric cigarette dispatches from the factory, control chip is sample detecting cell voltage in the time of standby, voltage is during lower than setting value, alarm lamp interval quick flashing, be conducive to producer, terminal sale, client and learn the situation of its electric weight deficiency, producer, terminal sale can stop the outflow market of defective products, and the situation of avoiding client to return goods and complaining is conducive to improve the prestige of producer; Client's this function of also taking like a shot, by this function, when client in use learns that by the warning of alarm lamp cell voltage is low, has grace time to prepare to change, and facilitates client to change use, further improves its commercial value.
Brief description of the drawings
Fig. 1 is the control circuit schematic diagram of disposable electric cigarette in conventional art.
