Description
Technical Field
The invention relates to an atomizer of aerosol, in particular to an atomizer which is provided with a plurality of atomizing cores and can automatically adapt to the conversion of oral and pulmonary inhalation volumes.
The invention also relates to a switching control method of the atomizer.
Background
When the electronic smoke sol is sucked, two modes of mouth suction and lung suction exist. By mouth-inhaling is meant simply inhaling the e-smoke aerosol into the inlet chamber and then directly exhaling, the volume of the oral cavity being small and therefore requiring a small amount of aerosol. The electronic cigarette operating conditions required at this time produce a smaller amount of aerosol. By pulmonary inhalation, it is meant that the aerosol is drawn through the mouth into the lungs, filling the alveoli as much as possible, and then exhaled again. Due to the large intrapulmonary volume, the required smoking volume is also large, requiring the electronic cigarette to produce a relatively large amount of aerosol. The state of mouth sucking and lung sucking can be converted, and for a smoker of the electronic cigarette, the electronic cigarette is in a leisure state and is in an arbitrary state, so that the conversion from mouth sucking to lung sucking is probably an occasional idea conversion, the conversion time is short, the paroxysmal is strong, and the conversion can be carried out only after the smoking is started. Therefore, it is generally not time to perform manual or programmed power adjustment, and both manual and programmed power adjustment cannot achieve the function of switching between oral inhalation and pulmonary inhalation at will in time. It is necessary for the electronic cigarette to have a self-detection and self-adaptive adjustment function, and the electronic cigarette is determined as lung inhalation when the user is detected to have large and fast inhalation amount, and is determined as mouth inhalation when the user has small and slow inhalation amount. And the working state is automatically adjusted according to the detection and judgment result, and the function is not really realized in the field of the electronic cigarette at present.
If only be provided with single atomizing core in general atomizer, the electron smog spinning disk atomiser of single atomizing core can only change heating power through changing parameters such as supply voltage, electric current, realizes the regulating action of atomization effect and atomizing volume when using. However, this kind of adjustment method has strong limitations, the length and diameter of the electronic cigarette heater resistor are determined, and the resistance value of the resistor is also determined, and even if the heating power can be changed by adjusting the power supply voltage and current, the general resistor heater is difficult to bear the multiple of the increased voltage or current, otherwise the problem of high temperature fusing is easy to occur, the adjustment amount is limited, the conversion between the aerosol volumes required from mouth inhalation to lung inhalation is generally increased by more than several times, and the heating power is required to be increased by several times. Therefore, the atomizing core of the single heating element can not adapt to the conversion from the mouth inhalation to the lung inhalation of the electronic cigarette at any time even through the self-adaptive adjustment.
In the atomizer that appears later, it can set up a plurality of heat-generating bodies, sets for the quantity that the heat-generating body worked according to the demand of the volume of inhaling, realizes that atomizing volume and volume of inhaling are adjusted. The specific structure is that the atomization core is provided with a plurality of heating wires which are connected in parallel, and the atomization core is provided with a uniform oil inlet hole, an air inlet hole and an air outlet hole. When a heating wire is opened to work under the requirement of common smoking, simple small smoke amount smoking is carried out, and the oil inlet and the air inlet work at the moment. And then need adjust when needing the increase to inhale the food intake and open two or a plurality of heater simultaneous workings, inlet port and the inlet port at this moment still keep same operating condition, still can be with original mode oil feed or admit air. The same air inlet hole and oil inlet hole are used from the heating of one heating wire to the heating of a plurality of heating wires. And to each group of heater, only one most suitable oil inlet air inflow is provided, and the best atomization effect can be achieved only if the oil inlet amount and the air inflow amount are well matched with the working amount of the heater. In the structure of the same oil inlet hole and the same air inlet hole, the oil inlet amount and the air inlet amount are difficult to be in the best working state no matter the size. If the relative oil inlet quantity and the air input quantity are larger when a group of heating wires work, the atomization temperature is insufficient, the atomization effect is influenced, and even the atomization temperature cannot be reached because the group of heating wires are submerged by a large amount of tobacco tar. When the plurality of groups of heating wires work, the problem of small oil inlet amount relatively occurs, and the phenomenon of dry burning caused by insufficient supply of tobacco tar can be caused. The air flow speed is slow when the relative air inflow is small, the aerosol sucking speed is slow, the atomization effect is also influenced, and the problem of too low concentration of atomized aerosol is caused when the relative air inflow is large.
Thus, although a plurality of atomizing heaters are provided, the best atomization is not achieved because independent control is not achieved. Moreover, the on or off of the plurality of heating wires is still realized through manual adjustment or program control, and cannot be automatically adjusted according to the size of the food intake.
The inventor develops an atomizer capable of self-adapting mouth-lung conversion of the food intake based on the defects and combined with the structure of the multiple heating element atomizing core, so as to overcome the defects.

A double-air-passage component 4 is arranged, double air flow passages of the double-air-passage component are of an integral structure and are butted with a double cover body 6, a first air passage 41 and a second air passage 42 are formed inside the double-air-passage component, the first air passage 41 is communicated with a first atomizing core air flow passage 711, and the second air passage 42 is communicated with a second atomizing core air flow passage 721.
The first air passage 41 and the second air passage 42 form a common chamber at the upper end of the double air passages 4, and the air flows of the double air passages are mixed and merged with each other and buffered to form the air flow buffer chamber 3. A negative pressure switch 5 is provided at a communication position of the second air passage 42 and the airflow buffer chamber 3, and the negative pressure switch is a mechanical switch and can sense the pressure state of the airflow buffer chamber 3. The upper end of the double air passage 4 is in sealed butt joint connection with the suction nozzle 1.
The bottom end of the double-shell body 8 is fixedly sealed and arranged on the base 11, the base 11 is provided with a bottom end accommodating space of the double-shell body 8 and is provided with a transverse air inlet hole which is respectively a first air inlet channel 111 and a second air inlet channel 112 which are respectively communicated with the transverse first air inlet hole 91 and the transverse second air inlet hole 92 at the bottom of the double-shell body 8, and the transverse air inlet channel of the base 11 is communicated with the atmosphere. In this embodiment, the hole is formed from the end surface of the base 11 after being bent downward.
In this embodiment, a power control device is further required, and the power control device supplies power to the two electrodes 10 after being abutted to the atomizer, and can be controlled separately. The heating control system of the second atomizing core is linked with the negative pressure switch 5, and when the negative pressure switch 5 is closed, the second double electrode 102 is not powered, namely the second atomizing core does not work. When the negative pressure switch 5 is opened, the second atomizing core works, and the negative pressure switch 5 is set to be in a normally closed state.
As shown in fig. 3, the negative pressure switch 5 of the present embodiment is a mechanical switch, is a spring pressure valve provided at the outlet of the second air passage 42, and is composed of a return spring 51, a valve cover 52, a valve body 53, and a vent hole 54. The valve body 53 is a cylindrical structure and is matched with the inner wall of the second air passage 42 to slide, the cylindrical hollow part of the valve body 53 is communicated with the air passage 42, the wall surface of the valve body 53 is provided with a vent hole 54, the valve cover 52 is arranged at the upper part of the valve body 53 and can integrally cover the valve body 53 and the upper end surface of the second air passage 42, and the reset spring 51 presses the valve cover 52 from the upper side. When the negative pressure of the air flow buffer chamber 3 does not reach the threshold value of the negative pressure switch 5, the pressure of the return spring 51 is greater than the negative pressure, and at this time, the valve cover 52 and the valve body 53 are not operated, and the air flow cannot be communicated with each other in a state where the valve cover 52 covers the air passage 42 and the valve body 53. And once the negative pressure of the airflow buffer cavity is greater than the elastic force of the return spring, the valve body 53 and the valve cover 52 can be moved upwards by overcoming the spring pressure until the vent hole 54 is exposed to the position of the airflow buffer cavity 3, and at the moment, the airflow buffer cavity can be communicated with the air passage 42 through the vent hole 54, so that the ventilation effect of the negative pressure switch is realized.
In the product of this embodiment, after the double electrode 10 and the double case 8 are sealed and butted, the oil conductor 7 and the heating element are installed to electrically connect the heating element and the electrode, the double cover 6 is sealed and covered from the upper side, and the double air duct 4 and the negative pressure switch 5 are installed. Then the integral atomizing core is assembled on the base 11. The housing 2 and the mouthpiece 1 are assembled to form a complete atomiser. When the atomizer is used, tobacco tar is filled and the power supply is switched on, and the smoking function can be realized by turning on the switch.
The atomizer of this embodiment sets up the atomizing core of two sets of mutual independent control in the atomizing cavity, and operating condition can be controlled respectively to two sets of atomizing cores, changes operating condition when needs, makes to be in single atomizing core work and two sets of atomizing core simultaneous working two kinds of states respectively.
The working process of the product of the embodiment is as follows: when starting to open the power and inhale, negative pressure switch 5 is in the normally closed state, and the second atomizing core does not work this moment, and only first atomizing core work is in conventional small amount of mouth sucking state automatically, and single atomizing core electron cigarette is fairly. When the smoking amount of a smoker is increased suddenly, namely the smoking amount and the smoking speed are increased, the air flow speed is also increased, a larger negative pressure is generated at the air flow buffer cavity 3 at the moment, when the threshold value of the negative pressure switch 5 is reached, the negative pressure switch 5 is opened, and the air flow channel of the second atomizing core is unblocked. And a second atomizing core controller linked with the negative pressure switch 5 is turned on to control the second atomizing core to heat. The second atomizing core starts to work to increase the smoke quantity and form a lung-inhaling state with large smoke quantity. When the sucking amount and the sucking speed are restored to the mouth sucking state again, the airflow pressure of the airflow buffer cavity 3 returns to normal, and the airflow buffer cavity is automatically closed when the airflow pressure is lower than the threshold value of the negative pressure switch 5. The second atomization core controller in linkage stops working and restores the mouth suction state. Thereby achieving the function of self-adapting oropulmonary transformation.
Example 2:
the present embodiment is a structural change based on embodiment 1, and the connection structure does not change, but the number of groups of atomizing cores can be increased, and the number of atomizing cores can be increased to three, four or more groups according to the requirement of the overall space of the atomizer. And only the negative pressure switch is arranged at the communication position of the airflow channel of the subsequent atomizing core of the second group of atomizing cores in the airflow buffer cavity, and the threshold value of the negative pressure switch is gradually increased. If the negative pressure switch threshold of the second atomization core is 950 hectopascal, the threshold of the third atomization core is set to 900 hectopascal, etc. The numerical values are merely for illustrative purposes and may be specifically set according to the amount of the food to be sucked.
Example 3:
the basic structure of this embodiment is the same as that of embodiment 1, and in order to realize true adaptive oropulmonary inhalation conversion, a negative pressure switch 5 may be provided at a communication position between the air passage 41 of each group of atomizing cores and the airflow buffer chamber 3, that is, a negative first pressure switch is provided at a communication position between the first air passage 41 and the airflow buffer chamber 3, and a second negative pressure switch is provided at a communication position between the second air passage 42 and the airflow buffer chamber 3. And the negative pressure switches are respectively in linkage control with the heating controllers of the atomization cores, namely when the corresponding negative pressure switches are turned on, the corresponding atomization cores start to heat. The starting threshold values of the first negative pressure switch and the second negative pressure switch are different, and the first starting with the smaller starting threshold value starts working. If the first atomizing core is set to work first, the starting pressure of the first atomizing core can be set to be 1000 hectopascal, and the starting pressure of the second atomizing core can be 950 hectopascal.
Example 4:
the negative pressure switch 5 described in embodiments 1 to 3 is a mechanical switch, and is an elastic valve, and is a normally closed mechanical switch that overcomes the elastic force of the spring 51 when the negative pressure reaches a threshold value, and is compressed to open, and returns to a closed state under the pressure of the spring 51 when the negative pressure is below the threshold value.
If the negative pressure switch is linked with the atomizing core heating controller, the action of the negative pressure switch 5 needs to be converted into an electric signal, so that corresponding devices such as connecting wires and the like need to be added. A more complicated electrical connection structure is required. In order to avoid a complex electrical connection structure, an airflow sensor can be arranged in an airflow channel of each atomization core, and particularly can be arranged at an air inlet 9 of the atomization core, and heating is controlled to be turned on when the airflow passing through the position is sensed. Since the position of the air inlet hole 9 is relatively close to the power supply control device, it is relatively easy to arrange an electric connection structure. Specifically, if the first air intake holes 91 and the second air intake holes 92 are merged at the base 11 to form a common air intake chamber, the airflow sensors are respectively disposed at the communication positions of the airflow passages of the first atomizing core or the second atomizing core and the common air intake chamber. If the first air inlet hole 91 and the second air inlet hole 92 are respectively and independently arranged, the airflow sensors are directly arranged at the first air inlet hole 91 and the second air inlet hole respectively, and the purpose is to realize that the airflow sensors are respectively arranged in the airflow channels of the atomizing cores where the airflow sensors are respectively arranged.
The structure self-adaptability of this embodiment is more strengthened, when just beginning smoking action, is in standby state, and when no air current passes through first atomizing core, the air current sensor perception of the 91 department of first atomizing core air inlet hole can not pass through, and first atomizing core does not heat the work this moment, and when the smoking air current produced, first atomizing core just began to work, and the heating atomization is atomizing core department operating condition when avoiding not smoking. Meanwhile, only after the negative pressure switch 5 is turned on and air flows in the second atomization core, the second atomization core starts to heat, and misoperation is avoided.
Example 5:
on the basis of the above embodiment, more groups of atomizing cores may be provided, and in addition to the first atomizing core and the second atomizing core, third to nth atomizing cores may be provided. Negative pressure switches are arranged at the communicated positions of the air passages of all the atomizing cores and the air flow buffer cavity, and air flow sensors are arranged at the positions of the air inlets of all the atomizing cores. The threshold value of the negative pressure switch of the atomizing core is gradually increased, for example, the threshold value of the first negative pressure switch of the atomizing core is 1000 hectopascal, the threshold value of the second negative pressure switch of the atomizing core is 950 hectopascal, the threshold pressure of the third negative pressure switch of the atomizing core is 900 hectopascal, and the like. Only with this arrangement will a gradual opening occur with increasing suction pressure. And along with the difference of suction pressure, the operating condition of atomizing core also can appear first atomizing core work, and second atomizing core and first atomizing core simultaneous working, third atomizing core and second, first atomizing core simultaneous working wait state.
Example 6:
in the embodiment, an electronic negative pressure switch is used instead of a mechanical negative pressure switch, and specifically, an electronic air pressure gauge may be disposed at the airflow buffer chamber 3, and an airflow valve may be disposed at a position where the airflow passage 41 or 42 communicates with the airflow passage, so as to open or close the airflow passage. The electronic air press is linked with the airflow valve, and when a certain suitable negative pressure value is reached, the corresponding airflow valve is opened, so that self-adaptive control is realized. In the embodiment, an air flow sensor at the air inlet can be omitted, and the current on-off of the atomizing core heating body is controlled by the pressure sensed by the electronic pressure gauge.

firstly, the electronic cigarette switch is turned on, the first atomizing core starts to work, the aerosol generated by the first atomizing core is inhaled, and the electronic cigarette is in a mouth inhalation state. Meanwhile, the negative pressure switch 5 detects the suction pressure of the airflow buffer cavity 3, when the suction pressure reaches the opening negative pressure threshold of the negative pressure switch 5, the negative pressure switch 5 is opened, the second atomization core starts to work, and the second atomization core generates aerosol and is in a lung suction state. When the lung suction state is finished and the suction pressure is reduced, the negative pressure of the airflow buffer cavity 3 is reduced, and when the negative pressure is lower than the opening negative pressure threshold of the negative pressure switch 5, the negative pressure switch 5 is closed again and enters the mouth suction state again. The stop mouthpiece state requires the electronic cigarette switch to be closed.
The atomizer of example 2 of the present invention was operated as follows:
first, open the electron cigarette switch, get into standby state, the negative pressure switch of first atomizing core and second atomizing core all is in the off-state, and the atomizing core is all out of work. When the first mouth starts to suck, the negative pressure switch detects the smoking negative pressure of the airflow buffer cavity 3, when the negative pressure reaches the opening threshold of the first atomizing core negative pressure switch, the first atomizing core negative pressure switch is opened, and the first atomizing core is controlled to be opened to start heating and atomizing. Meanwhile, the second atomization core negative pressure switch detects the negative pressure of the airflow buffer cavity 3, and when the negative pressure is not changed or changed to reach the opening threshold of the second atomization core negative pressure switch, the first atomization core still works and is in a mouth suction state. When the negative pressure of the airflow buffer cavity 3 reaches the opening threshold of the second atomization core negative pressure switch, the second atomization core negative pressure switch is turned on to control the second atomization core to heat, and then the second atomization core is in a lung inhalation state. When the lung suction state is finished and the suction pressure is reduced, the negative pressure of the airflow buffer cavity is reduced, and when the negative pressure is lower than the opening negative pressure threshold of the second negative pressure switch, the second negative pressure switch is closed again to enter a standby state, and then the mouth suction state is entered. When the smoking pressure is continuously reduced to the opening threshold pressure of the first atomization core negative pressure switch, the whole electronic cigarette of the first atomization core negative pressure switch is closed again to enter a standby state.
The structure of embodiment 2 increases the work flow after the airflow sensor is provided.

When beginning first mouth to inhale, the smoking negative pressure of air current cushion chamber 3 is detected to the negative pressure switch, and when negative pressure reached first atomizing core negative pressure switch and opened the threshold value, first atomizing core negative pressure switch opened, and first atomizing core airflow sensor sensing simultaneously has the air current to pass through, and control is opened first atomizing core and is begun to heat the atomizing. Meanwhile, the second atomization core negative pressure switch detects the negative pressure of the airflow buffer cavity 3, and when the negative pressure is not changed or changed to reach the opening threshold of the second atomization core negative pressure switch, the first atomization core still works and is in a mouth suction state. When the negative pressure of the airflow buffer cavity 3 reaches the opening threshold of the second atomization core negative pressure switch, the second atomization core negative pressure switch is opened, the second atomization core airflow sensor detects that the second atomization core has airflow to pass through, the second atomization core is controlled to heat, and the second atomization core is in a lung inhalation state. When the lung suction state is finished and the suction pressure is reduced, the negative pressure of the airflow buffer cavity is reduced, when the negative pressure is lower than the opening negative pressure threshold of the second negative pressure switch, the second negative pressure switch is closed again, meanwhile, the airflow of the second atomizing core disappears, the second atomizing core airflow sensor controls the second atomizing core to stop heating work, the second atomizing core enters a standby state, and the second atomizing core enters the mouth suction state. Smoking pressure continues to reduce when first atomizing core negative pressure switch opens threshold pressure, closes first atomizing core negative pressure switch once more, and first atomizing core air current disappears, and first atomizing core air current sensor control first atomizing core stop work, and whole electron cigarette gets into standby state.

Meanwhile, the second atomization core negative pressure switch detects the negative pressure of the airflow buffer cavity 3, and when the negative pressure is not changed or changed to reach the opening threshold of the second atomization core negative pressure switch, the first atomization core still works and is in a mouth suction state. When the negative pressure of the airflow buffer cavity 3 reaches the opening threshold of the second atomization core negative pressure switch, the second atomization core negative pressure switch is opened, the second atomization core airflow sensor detects that the second atomization core has airflow to pass through, the second atomization core is controlled to heat, and the second atomization core is in a lung inhalation state. When the smoking amount is increased again, the negative pressure of the airflow buffer cavity is increased again until the negative pressure switch threshold value of the Nth atomizing core, the Nth atomizing core is opened to work, and aerosol generated by the work of all the atomizing cores is inhaled.
