Description
Technical Field
The invention relates to an aerosol atomizer, in particular to an atomizer with multiple atomizing cores, which can automatically adapt to oral-pulmonary intake conversion.
The invention also relates to a control method of the atomizer.
Background
When the electronic smoke sol is sucked, two modes of oral suction and lung suction exist. By oral inhalation is meant that only the electronic aerosol is inhaled into the inlet chamber and then directly exhaled, and the volume of the oral cavity is small, so that the amount of aerosol required is also small. The desired e-cigarette operating conditions at this time produce a smaller amount of aerosol. Pulmonary inhalation is the inhalation of aerosols into the lungs through the mouth and filling the alveoli as much as possible, followed by exhalation. Because of the large internal volume of the lung, the required intake is also large, and the electronic cigarette is required to generate a large amount of aerosol. The mouth sucking and lung sucking states can be converted, and for an electronic cigarette smoker, the electronic cigarette is easy to suck and is in a random state, so that the conversion from mouth sucking to lung sucking is likely to be an occasional idea conversion sometimes, the conversion time is quick, the burst is strong, and the conversion can be performed just after the start of sucking. Therefore, the manual adjustment and the program adjustment are not convenient to perform, and the manual adjustment and the program adjustment can not achieve the function of freely switching between oral inhalation and pulmonary inhalation in time. This requires the electronic cigarette to have a self-detecting and self-adapting function, and to determine lung inhalation when the user is detected to have a large inhalation amount and to determine mouth inhalation when the user is detected to have a small inhalation amount and to have a slow inhalation amount. And the working state is automatically adjusted according to the detection and judgment result, so that the function is not really realized in the current electronic cigarette field.
If only be provided with single atomizing core in the general atomizer, the electron smog spinning disk atomiser of single atomizing core can only be through changing the heating power of parameter change such as power supply voltage, electric current when using, realizes the regulation effect of atomizing effect and atomizing volume. However, the adjusting mode has strong limitation, the length and the diameter of the resistance of the heating wire of the electronic cigarette are determined, the resistance value of the resistance is also determined, even though the heating power can be changed through adjustment of the power supply voltage and the current, the common resistance heating wire is difficult to bear the voltage or the current which are increased by multiple, otherwise, the problems of high temperature fusing and the like are easy to occur, the adjusting quantity is limited, the transformation between the aerosol volume required by sucking the mouth to the lung is generally increased by more than several times, and the heating power is also required to be increased by several times. Therefore, the atomization core of the single heating body can not adapt to the instant conversion from mouth suction to lung suction of the electronic cigarette even through self-adaptive adjustment.
In the later atomizer, a plurality of heating elements can be arranged, the working quantity of the heating elements is set according to the demand of the intake, and the atomization amount and the intake are adjusted. The atomizing core is provided with a plurality of heating wires which are connected in parallel, and the atomizing core is provided with a uniform oil inlet hole, an uniform air inlet hole and an uniform air outlet hole. When a heating wire is opened to work in general smoking demands, simple small smoke sucking is carried out, and the oil inlet and the air inlet are both in work. When the intake needs to be increased, two or more heating wires need to be adjusted to be opened for simultaneous operation, and the oil inlet and the air inlet at the moment still keep the same working state, and oil or air can be fed in an original mode. The same air inlet hole and oil inlet hole are used from heating of one heating wire to heating of a plurality of heating wires. For each group of heating wires, only one most suitable oil inlet air inflow is needed, and only the oil inlet amount and the air inflow are matched with the working quantity of the heating wires, the best atomization effect can be achieved. In the structure of the same oil inlet and the same air inlet, the oil inlet amount and the air inlet amount are difficult to be in the optimal working state no matter the sizes. If the relative oil inlet amount and air inlet amount of a group of heating wires during operation can be larger, the atomization temperature can be insufficient, the atomization effect is affected, and even a large amount of tobacco tar is submerged, so that the atomization temperature can not be reached. The problem of small oil inlet amount can occur relatively when a plurality of groups of heating wires work, and the phenomenon of dry combustion can occur due to insufficient tobacco tar supply. The air flow speed is low when the relative air inflow is small, the aerosol sucking speed is low, the atomization effect is also affected, and the problem of too low concentration of the atomized aerosol is caused by the large relative air inflow.
Therefore, although a plurality of atomizing heating wires are provided, the best atomizing purpose is not achieved because independent control cannot be realized. Moreover, the switching on or off of the heating wires is still realized through manual adjustment or program control, and cannot be automatically adjusted according to the size of the intake.
The inventor combines the structure of multiple atomizing cores according to the defects, and develops an atomizer capable of self-adapting to the inhalation amount and switching between mouth and lung so as to overcome the defects.

The first heating body and the second heating body may be heating resistance wire spirals or cylindrical heating wire meshes, and although the structures of the first heating body and the second heating body are not shown in the drawings of the present embodiment, it is entirely conceivable to those skilled in the art.
The upper side of the double shell 8 is provided with a double cover 6, the double cover 6 is in sealing butt joint with the double shell 8, the first oil guide body 71 and the second oil guide body 72 are sealed in the double shell 8 after being in sealing butt joint with the double shell 8, an independent first atomization core and an independent second atomization core are respectively formed, and a first air outlet channel and a second air outlet channel are arranged on the double cover 6.
The double air passage assembly 4 is arranged, the double air passage assembly is in an integral structure and is in butt joint with the double cover body 6, a first air passage 41 and a second air passage 42 are formed in the double air passage assembly, the first air passage 41 is communicated with the first atomization core air passage 711, and the second air passage 42 is communicated with the second atomization core air passage 721.
The first air passage 41 and the second air passage 42 form a common chamber at the upper end part of the double air passage 4, and the air flows of the double air passages are mixed, converged and buffered to form an air flow buffer chamber 3. A negative pressure switch 5 is arranged at the communication position of the second air passage 42 and the air flow buffer cavity 3, and the negative pressure switch is a mechanical switch and can sense the pressure state of the air flow buffer cavity 3. The upper end of the double air passages 4 is in sealing butt joint with the suction nozzle 1.

This embodiment is perforated from the end face of the base 11 after being bent downward.
In this embodiment, a power supply control device is also required, and after the power supply control device is in butt joint with the atomizer, power is respectively supplied to the double electrodes 10, and the power supply control device can be respectively controlled. 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, that is, the second atomizing core does not work. When the negative pressure switch 5 is turned on, 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 cap 52, a valve body 53, and a vent hole 54. The valve body 53 is of a cylindrical structure and slides in cooperation with the inner wall of the second air passage 42, the cylindrical hollow part of the valve body 53 is communicated with the air passage 42, a vent hole 54 is arranged on the wall surface of the valve body 53, the valve cover 52 is arranged on the upper part of the valve body 53, the whole can cover the upper end surfaces of the valve body 53 and 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 larger than the negative pressure, at this time, the valve cover 52 and the valve body 53 do not act, and the air flow cannot be communicated at this time in a state that the valve cover 52 covers the air passage 42 and the valve body 53. Once the negative pressure of the air flow buffer cavity is larger than the elastic force of the return spring, the valve body 53 and the valve cover 52 can be moved upwards against the spring pressure until the vent hole 54 is exposed to the position of the air flow buffer cavity 3, and at the moment, the air flow buffer cavity and the air channel 42 can be communicated through the vent hole 54, so that the ventilation effect of the negative pressure switch is realized.
When the product of this embodiment is assembled, after the double electrode 10 is in sealing butt joint with the double shell 8, the oil guide body 7 and the heating body are installed, the heating body is electrically connected with the electrode, the double cover 6 is sealed and covered from the upper side, and the double air passage 4 and the negative pressure switch 5 are installed. The integral atomizing core is then assembled to the belt base 11. The housing 2 and the mouthpiece 1 are assembled to form a complete atomizer. When the atomizer is used, the cigarette oil is poured and the power supply is turned on, and the smoking function can be realized by turning on the switch.
The atomizer of this embodiment sets up two sets of mutually independent control's atomizing core in the atomizing chamber, and two sets of atomizing cores can control operating condition respectively, change operating condition when needs, make be in single atomizing core work and two sets of atomizing core simultaneous working two kinds of states respectively.
The working procedure of the product of this example is as follows: when the power supply starts to be turned on for sucking, the negative pressure switch 5 is in a normally closed state, the second atomization core does not work at the moment, only the first atomization core works, and the electronic cigarette is automatically in a conventional small-amount sucking state and is equivalent to a single atomization core electronic cigarette. When the smoker suddenly increases the smoke suction amount, namely the smoke suction amount and the smoke suction speed are increased, the air flow speed is also increased, at the moment, larger negative pressure is generated at the air flow buffer cavity 3, and when the threshold value of the negative pressure switch 5 is reached, the negative pressure switch 5 is turned on, and the air flow channel of the second atomization core is smooth. The second atomizing core controller which is linked with the negative pressure switch 5 is opened to control the heating work of the second atomizing core. The second atomizing core starts to work, the smoke quantity is increased, and a lung sucking state with large smoke quantity is formed. When the sucking quantity and the sucking speed are restored to the sucking state again, the air flow pressure of the air flow buffer cavity 3 returns to normal, and is automatically closed when the air flow pressure is lower than the threshold value of the negative pressure switch 5. The linked second atomizing core controller stops working and restores the mouth sucking state. Thereby achieving the function of self-adaptive oral-pulmonary conversion.
Example 2:
the present embodiment is a structural change based on embodiment 1, the connection structure is not changed, but the number of groups of atomizing cores can be increased, and the number of atomizing cores can be increased to three groups, four groups or more groups according to the overall space requirement of the atomizer. And a 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 and the airflow buffer cavity, and the threshold value of the negative pressure switch is gradually increased. If the threshold value of the negative pressure switch of the second atomizing core is 950 hundred pascals, the threshold value of the third atomizing core is 900 hundred pascals, and the like. The numerical values herein are merely illustrative of the principles, and may be specifically set according to the intake amount.
Example 3:
the basic structure of this embodiment is the same as that of embodiment 1, and in order to realize the real self-adaptive oral-pulmonary inhalation conversion, a negative pressure switch 5 may be further disposed at the communication position of the air passage 41 of each group of atomizing cores and the air flow buffer cavity 3, that is, a negative first pressure switch is disposed at the communication position of the first air passage 41 and the air flow buffer cavity 3, and a second negative pressure switch is disposed at the communication position of the second air passage 42 and the air flow buffer cavity 3. And the negative pressure switches are respectively in linkage control with the heating controllers of the atomizing cores, namely when the corresponding negative pressure switches are turned on, the corresponding atomizing cores start to heat. The starting threshold values of the first negative pressure switch and the second negative pressure switch are generally different, and the first starting with the small starting threshold value starts to work. If the first atomizing core is arranged to work first, the starting pressure of the first atomizing core can be set to be 1000 hundred Pa, and the starting pressure of the second atomizing core can be set to be 950 hundred Pa.
Example 4:
the negative pressure switch 5 described in embodiments 1 to 3 is a mechanical switch, is an elastic valve, overcomes the elastic force of the spring 51 when the negative pressure reaches a threshold value, is compressed and opened, and returns to the closed state under the pressure of the spring 51 when the negative pressure is below the threshold value, and is a normally closed mechanical switch.
If the negative pressure switch is linked to the atomizing core heating controller at this time, the action of the negative pressure switch 5 needs to be converted into an electric signal, and thus a corresponding device such as a connecting wire or the like needs to be added. A more complex electrical connection structure is required. In order to avoid a complex electrical connection structure, an air flow sensor can be arranged in the air flow channel of each atomizing core, and the air flow sensor can be particularly arranged at the air inlet hole 9 of the atomizing core, and heating is controlled to be opened when sensing that air flow passes through the air flow channel. Since the position of the air inlet 9 is relatively close to the power control means, it is relatively easy to provide an electrical connection. Specifically, if the first air intake hole 91 and the second air intake hole 92 are merged at the base 11 to form a common air intake chamber, the air flow sensor is disposed at a communication position of the air flow passage of the first atomizing core or the second atomizing core, respectively, with 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 air flow sensor is directly arranged at the first air inlet hole 91 and the second air inlet hole respectively, and the purpose is to respectively arrange in the air flow channels of the atomizing cores.
The self-adaptive capability of the structure of this embodiment is more strengthened, when just starting smoking action, is in standby state, and when no air current passed through first atomizing core, the air current sensor of 91 department of first atomizing core air current inlet port was unable to be perceived the air current and is passed through, and first atomizing core is not heated the work this moment, and when smoking air current produced, first atomizing core just begins to work, heats the atomizing, avoids the atomizing core department operating condition when not smoking. Meanwhile, only after the negative pressure switch 5 is opened, when air flows through the second atomization core, the second atomization core starts to heat, so that misoperation is avoided.
Example 5:
on the basis of the above embodiment, more groups of atomizing cores may be provided, and a third through nth atomizing cores may be provided in addition to the first and second atomizing cores. Negative pressure switches are arranged at the communication 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, such as a first atomizing core negative pressure switch threshold value of 1000 hundred Pa, a second atomizing core negative pressure switch threshold value of 950 hundred Pa, a third atomizing core negative pressure switch threshold value of 900 hundred Pa and the like. Only if so arranged will a gradual opening occur with increasing suction pressure. And along with the difference of suction pressure, first atomizing core work can also appear in the operating condition of atomizing core, and second atomizing core and first atomizing core simultaneous working, and the state such as third atomizing core and second, first atomizing core simultaneous working.
Example 6:
in this embodiment, an electronic negative pressure switch is used instead of a mechanical negative pressure switch, specifically, an electronic air pressure gauge may be disposed at the air flow buffer cavity 3, and an air flow valve is disposed at a position where the air flow channel communicates with the air flow channel through the air flow channel 41 or 42, so as to open or close the air flow channel. And the electronic air press is linked with the air flow valve, and the corresponding air flow valve is opened when a certain proper negative pressure value is reached, so that self-adaptive control is realized. In this embodiment, an air flow sensor at the air inlet hole can be omitted, and the pressure sensed by the electronic pressure gauge is used to control the current on-off of the atomizing core heating body.

firstly, an electronic cigarette switch is turned on to start sucking, a first atomization core starts working, aerosol generated by the first atomization core is sucked, and the electronic cigarette is in a mouth sucking state. Meanwhile, the negative pressure switch 5 detects the suction pressure of the airflow buffer cavity 3, when the suction pressure reaches the negative pressure starting threshold value of the negative pressure switch 5, the negative pressure switch 5 is started, the second atomization core starts to work, aerosol is generated by the second atomization core, and the second atomization core is in a lung suction state. When the lung sucking state is finished and the sucking 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 value of the negative pressure switch 5, the negative pressure switch 5 is closed again and the sucking state is entered again. Stopping the mouth suction state requires closing the electronic cigarette switch.
The atomizer of example 2 of the present invention works as follows:
firstly, an electronic cigarette switch is turned on, a standby state is entered, negative pressure switches of a first atomization core and a second atomization core are in a closed state, and the atomization cores do not work. When the first mouth sucking starts, the negative pressure switch detects the smoking negative pressure of the airflow buffer cavity 3, and when the negative pressure reaches the opening threshold value of the first atomization core negative pressure switch, the first atomization core negative pressure switch is opened, and the first atomization core is controlled to be opened to start heating atomization. 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 does not reach the opening threshold value of the second atomization core negative pressure switch, the second atomization core negative pressure switch still works and is in a mouth sucking state. When the negative pressure of the airflow buffer cavity 3 reaches the opening threshold value of the second atomization core negative pressure switch, the second atomization core negative pressure switch is turned on, and the second atomization core is controlled to heat, so that the lung sucking state is achieved. When the lung sucking state is finished and the sucking pressure is reduced, the negative pressure of the airflow buffering cavity is reduced, and when the negative pressure is lower than the opening negative pressure threshold value of the second negative pressure switch, the second negative pressure switch is closed again and enters a standby state, and then the air flow buffering cavity is also in the sucking state. When the smoking pressure continues to be reduced to the opening threshold pressure of the first atomization core negative pressure switch, the first atomization core negative pressure switch is closed again, and the whole electronic cigarette enters a 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 does not reach the opening threshold value of the second atomization core negative pressure switch, the second atomization core negative pressure switch still works and is in a mouth sucking state. When the negative pressure of the air flow buffer cavity 3 reaches the opening threshold value of the second atomization core negative pressure switch, the second atomization core negative pressure switch is turned on, the second atomization core air flow sensor detects that the second atomization core passes through the air flow, and the second atomization core is controlled to heat and work, so that the air flow buffer cavity is in a lung suction state. When the lung sucking state is finished and the sucking pressure is reduced, the negative pressure of the air flow buffer cavity is reduced, when the negative pressure is lower than the opening negative pressure threshold value of the second negative pressure switch, the second negative pressure switch is closed again, meanwhile, the second atomization core air flow disappears, the second atomization core air flow sensor controls the second atomization core to stop heating, the second atomization core air flow sensor enters a standby state, and the second atomization core air flow sensor enters the sucking state again.
