Description
Technical Field
The invention relates to the field of electronic atomization, in particular to an electronic atomizer capable of reducing condensate and an atomization method.
Background
The basic principle of the electronic atomizer is that the liquid is heated by the electronic heating device and atomized to form aerosol, and a user applies negative air pressure to the suction port of the atomizer, so that the aerosol is extracted from the electronic heating device for use. Electronic atomizers find wide application in medical, recreational, and electronic cigarette products.
The existing electronic atomizer is characterized in that the air pressure drop in the atomizer is detected by an air flow sensor to control the start and stop of the atomization process: if the air pressure in the electronic atomizer is lower than a certain threshold value P, judging that the electronic atomizer is in a sucked process, and at the moment, switching on a circuit of the electronic heating device by a control circuit, and heating the electronic heating device to start an atomization process; when the air pressure is higher than the threshold value P, the end of the sucking process is judged, the control circuit cuts off the power supply of the electronic heating device, and the atomization process is ended.
However, after the electronic heating device is powered off, there is still residual temperature, which can cause the atomization process to last for a period of time, but because the suction process is finished at this time, the aerosol atomized by the residual temperature cannot be discharged out of the atomizer, and condensate residues are finally formed. The condensate residue not only influences the use experience and causes waste, but also gradually accumulates along with the increase of the use times, and leakage is easily caused.

Detailed Description
Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention.
Reference is made to the accompanying drawings. It should be noted that, the illustrations provided in the present embodiment merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complex. Unless otherwise indicated, terms such as "upper", "lower", "left", "right", and the like, as used herein, refer to the perspective of the viewer of the drawings.
Fig. 1 is a logical block diagram showing the basic structure of the electronic atomizer of the present invention. The electronic atomizer of the invention comprises an air pressure sensor 1 for detecting air pressure changes in the atomizer and forming a signal to be sent to a control circuit 2. The control circuit 2 is generally composed of an embedded system, a programmable logic device, etc., and is used for receiving a control signal and running a control program to control the working state of the electronic heating device 3, such as on-off of a circuit or the magnitude of power supply. The electronic heating device 3 is used for heating the liquid to form an aerosol.
Control logic in the control circuit 2 will be described in connection with fig. 2-3, wherein fig. 2 shows control logic of the control circuit 2. Fig. 3 is a graph showing the variation of air pressure in the atomizer during use. The primary use process of the atomizer starts from applying negative pressure to the suction port, the negative pressure is gradually increased from small to large in the use process, the negative pressure becomes smaller after reaching the vertex, and the primary use process of the negative pressure returns to zero is finished. Without loss of generality, the curves C1 (solid line) and C2 (dashed line) in fig. 3 represent the use process of two different durations and forces, respectively.
S1: the air pressure sensor monitors whether the air pressure in the atomizer is less than the start point air pressure P1, and if so, steps S21 and S21' are simultaneously performed. As mentioned above, the use of the atomizer starts with applying a negative pressure to the suction opening, so that the value of the negative pressure in the atomizer can characterize the beginning of the atomizer use. The threshold value of the start point P1 obviously needs to be higher than the air pressure peak (lowest point), but if the setting is too high, erroneous judgment is easily caused, and if the setting is too low, the use affects the use experience, and is generally set between-100 Pa and-400 Pa.
S21': the heating circuit is started. Specifically, the operating circuit of the electronic heating device 3 is started to keep a heated state to heat the liquid so as to generate aerosol.
S21: and dynamically detecting the air pressure peak. The step is to monitor the air pressure change in the atomizer, find the peak value of the negative pressure, and then execute step S22. As in fig. 3, vertex 1 is found for curve C1 and vertex 2 is found for curve C2.
S22: the turn-off point threshold value used this time is calculated from the negative pressure vertex, and then step S23 is executed. It is readily understood that: for the purpose of utilizing the residual temperature of the electric heater and reducing condensate, the turn-off point should be lower than the start-up point air pressure P1. In this example, the threshold of the turn-off point is calculated by multiplying the negative pressure peak value by a percentage, preferably 30% -50%.
The steps S21 and S22 are preferable steps, and the process is not exactly the same for each use (suction) of the nebulizer, and the air pressure vertex in the nebulizer is uncertain for each use in this scenario, so the steps S21 and S22 need to be performed for dynamic detection, so that the closing point is finely calculated for each use. However, if the application scenario is that the usage (pumping) process is homogeneous, such as a medical spray generator, each pumping is machine or program controlled, and the vertex is determined, the air pressure threshold of the turn-off point can be directly calculated through the vertex, and the special dynamic detection of the vertex is not necessary each time.
S23: monitoring and judging whether the air pressure in the atomizer is higher than the threshold value of the turn-off point, and if so, executing step S24; otherwise, continuing to monitor.
S24: the heating circuit is turned off.
In the above steps S23 and 24, the control circuit 2 turns off the operation circuit of the electronic heating device 3 at the off-point. As shown in fig. 3, for the use process C1, the use process is not finished when the point 1 is turned off, the heating circuit of the electronic heater 3 is turned off, and during the use process after the point 1 is turned off, the liquid is atomized by the residual temperature of the electronic heater 3, and at this time, the aerosol atomized by the residual temperature is pumped out of the atomizer because the inside of the atomizer is still under negative pressure, so that condensate is greatly reduced. Similar is true for use procedure C2: at the off-point 2 the heating circuit of the electronic heater 3 is turned off, after which the process uses the electronic heater residual temperature for atomization.
The present invention also provides an atomization method, the flow of which can be shown in fig. 2, and the descriptions of the steps are the same as above, and are not repeated.
As described above, according to the electronic atomizer and the atomization method of the present invention, by selecting different thresholds for turning on and off the heating circuit, the heating device is powered off before the end of the use process, so that the aerosol generated by the remaining temperature of the heater can be discharged out of the atomizer to the maximum extent, and condensate is reduced. According to a preferred embodiment, an optimal closing threshold can be calculated for each use, further optimizing the use.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention, e.g., the control circuit may only control the on and off states of the electric heating device circuit. In practice, the control logic can be further refined, for example, a control circuit adopts machine learning and artificial intelligence technology to analyze the characteristics of each use, the working circuit of the electronic heating device is not directly disconnected at the disconnection point, but only the output power of the electronic heating device is gradually reduced until the heating is finally closed, so that the atomization process is controlled more precisely. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
