Description

Electronic atomization device

Technical Field

The invention relates to the technical field of electronic atomization, in particular to an electronic atomization device.

Background

Electronic atomization devices, as a nicotine delivery system, require the atomization of tobacco tar into small droplets to effect the delivery process. The atomization methods are different, and the existing atomization technologies include heating atomization, ultrasonic mesh vibration atomization, airflow impact atomization, electrospray atomization and the like.

Due to different atomization principles, the particle sizes of the formed aerosols are different, and the aerosols with different sizes also affect the mouthfeel of the electronic atomization device. Further, the deposition of aerosol on human body and the absorption efficiency of nicotine are affected.

Generally, aerosol generated by heating and atomizing has smaller particle size (less than 1 μm), so that the aerosol can more easily enter the lung of a human body through the oral cavity and the respiratory tract. Therefore, the method is the atomization technology of the electronic atomization device which is most widely applied at present. It also has certain problems such as difficulty in depositing in the mouth to form a moist, sweet mouthfeel. During the high-temperature atomization process of the tobacco tar, flavor substances added inside the tobacco tar can be changed, so that the aroma feeling of the tobacco tar during the smoking process is different from the aroma feeling of the tobacco tar.

On the other hand, aerosol generated by using an ultrasonic screen hole vibration atomization mode has larger particle size (more than 1 mu m) and is easier to deposit in the oral cavity, so that moist and sweet mouthfeel can be brought, and on the other hand, chemical components in the tobacco tar are always kept in a relatively stable state in the liquid drop crushing process, so that the feeling of the tobacco tar is close to the feeling of the tobacco tar. However, the atomization method has some problems, such as low smoke temperature, cool smoke felt by users, and insufficient smoke felt by people due to less smoke generated.

With the development of electronic atomization device products, the demands of consumers on the smoke mouthfeel of the electronic atomization device are more and more diversified, part of consumers like dry and smooth mouthfeel, and part of consumers like wet, fragrant and sweet mouthfeel. On the other hand, even the same user may have directional demand for the taste when changing the flavor of tobacco tar, and the demand becomes a problem to be solved urgently in the field of electronic atomization devices.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic view of an electronic atomization device according to an embodiment of the present invention, the electronic atomization device includes: a reservoir 1 for storing an aerosol-generating substrate; a first aerosol-generating unit 2 for atomizing the aerosol-generating substrate within the liquid storage chamber 1 to generate a first aerosol of a first average particle size; a second aerosol-generating unit 3 for generating a second aerosol of a second average particle size; the suction nozzle 4 is used for discharging the first aerosol and the second aerosol to the outside independently or after being mixed; wherein the first average particle size ranges from 0.1 to 10 μm, and the second average particle size ranges from 20um to 50 μm. For solving the single problem of electron atomizing device smog taste, set up first aerosol among the electron atomizing device of this application and produced unit 2 and second aerosol and produce unit 3 respectively for produce the aerosol that the average particle size is different, and discharge through suction nozzle 4 after mixing the aerosol that the average particle size is different, reach the user oral cavity, thereby make the smog particle size that gets into the user oral cavity different. As described in the background art, different particle sizes of aerosols can provide different user experiences, so that the smoke has various tastes. The electronic atomization device of the present application will be described in detail below.

The liquid storage cavity 1 is used for storing aerosol generating substrates, the aerosol generating substrates can be tobacco tar, health and medical atomization medicaments or chemical medicaments and the like, and the aerosol generating substrates are converted into aerosols with different particle sizes through the first aerosol generating unit 2 and the second aerosol generating unit 3. In order to control the proportion of the aerosols with different particle sizes in the smoke, the particle sizes of the aerosols converted by the first aerosol generating unit 2 and the second aerosol generating unit 3 are respectively within a preset range and are close to an average value. If the first average particle size of the first aerosol is predetermined to be 3.5 μm, the first aerosol-generating unit 2 is set so that the range of the number of particles formed by atomizing the first aerosol-generating unit 2 is controlled to be about 3.5 μm or 3.5 μm, such as 3.3 μm, 3.4 μm, 3.6 μm, 3.7 μm, and the like, so that the first average particle size of the first aerosol is 3.5 μm. The second average particle size of the second aerosol is controlled as above. The first aerosol and the second aerosol generated by the first aerosol generating unit 2 and the second aerosol generating unit 3, respectively, enter the mouthpiece 4 and reach the user's mouth either individually or after mixing in the mouthpiece 4. If the first aerosol or the second aerosol independently reaches the oral cavity of the user, smoke with single mouthfeel is formed, and if the first aerosol and the second aerosol are mixed and then reach the oral cavity of the user, the formed smoke with rich mouthfeel meets various requirements of the user.

Experiments show that partial particles inhaled into a human body through the nasal cavity and the oral cavity can be deposited on each part of a respiratory tract according to the particle size through human breath, and the deposition conditions of smoke with different particle sizes in human organs are as follows: filtering and blocking particles with particle size of more than 10 μm in oral cavity, depositing particles with particle size of 7-10 μm in nasal cavity, depositing particles with particle size of 5-7 μm in pharynx and larynx, depositing particles with particle size of 3-5 μm in trachea and main bronchus, depositing particles with particle size of 1-3 μm in bronchiole in lung, and depositing particles with particle size of less than 1 μm in alveolus. The numerical range of the first average particle size of the first aerosol is set to be 0.1-10 mu m, the first average particle size cannot be deposited in the oral cavity, the first average particle size is directly deposited in a respiratory tract and an alveolus through a respiratory system of a human body, the human body feels dry and soft when smoke is generated, the numerical range of the second average particle size of the second aerosol is set to be larger than 10 mu m, the particle size is large, the second average particle size is filtered and blocked by the oral cavity, and the second average particle size can be deposited in the oral cavity of the human body to form wet, fragrant and sweet taste. When the first aerosol and the second aerosol are mixed and then enter the oral cavity of a human body, the advantages of the two tastes are combined, various experiences are brought to users, and the use requirements of different users are met.

Preferably, the second average particle size of the second aerosol is set to a value in the range of 20 to 50 μm in this embodiment. Referring to fig. 2, fig. 2 is a schematic diagram illustrating the passing efficiency of aerosols with different particle sizes in human oral cavity, and it can be seen from fig. 2 that the aerosol with particle size less than 10 μm has a large passing rate in oral cavity, low deposition efficiency, small particle size and low deposition quality, and it is difficult to achieve a sufficient amount of aerosol to form a sweet taste. Experiments show that the smoke containing aerosol with the particle size of 3-4 mu m in a certain proportion almost has no sweet taste. Simulation results show that 20 μm size aerosols deposit in the human mouth at a rate of about 9.5%, whereas 20 μm size aerosols deposit at a rate of up to 40%, and therefore the preferred second aerosol should have a second mean particle size in the range of greater than 20 μm.

Meanwhile, the second average particle size of the second aerosol cannot be too large, the aerosol with the too large particle size cannot fly out along with the airflow due to too much deposition under the action of gravity, and the function of adjusting the mouthfeel cannot be achieved. According to a typical electronic atomization device air passage structure, the movement track of large-particle-size aerosol is researched, the flow parameter is 55ml within 3 seconds of standard, the length of the air passage is 20cm, the length of a large-particle-size aerosol atomization source is about 6mm, and the large-particle-size aerosol gradually settles and is lost on the wall surface of the electronic atomization device air passage structure along with the flowing of air flow. Based on the data, the length of the second aerosol atomization source in the embodiment is less than 6mm, so that the second aerosol atomization source is prevented from being too large, condensing and gathering on the inner wall of the air passage of the suction nozzle 4 in the use process, and being incapable of reaching the oral cavity of the user.

Still referring to fig. 2, when the particle size of the aerosol is increased to 100 μm, the passing efficiency is less than 30%. When a large amount of aerosol is deposited on the inner wall of the air passage, the taste is not improved, and liquid leakage is caused along with more and more accumulation. According to the difference of the aerosol passing efficiency, the upper limit of the aerosol particle size is preferably 50 μm, and the passing efficiency of the aerosol in the air passage of the electronic atomization device is about 70%.

In summary, the second average particle size of the second aerosol is set to a value in the range of 20 to 50 μm. In the range, the second aerosol has a large particle size and is filtered and blocked by the oral cavity, the passing efficiency in the oral cavity is about 40% -70%, part of the second aerosol can be deposited in the oral cavity of a human body to form a wet and sweet taste, the problem that the small-particle size aerosol with the particle size of less than 20 microns is not high in deposition efficiency and difficult to reach a sufficient amount to form the sweet taste is solved, and the large-particle size aerosol with the particle size of more than 50 microns is too low in passing efficiency and easy to deposit on the inner wall of an air passage and cannot reach the oral cavity of the human body.

Since the current single taste smoke cannot satisfy the user's various needs, the first aerosol has a first average particle size in the range of 0.1 to 10 μm, and the second aerosol has a second average particle size in the range of 20 to 50 μm. The particle size of the first aerosol is small, the aerosol with the small particle size is low in oral cavity deposition efficiency, small in particle size, low in quality and dry and astringent in taste, and the sweet taste is hardly formed in a sufficient amount. The second aerosol has larger particle size, and the aerosol with larger particle size is easier to deposit in the oral cavity, so the second aerosol can bring moist and sweet mouthfeel, but the smoke temperature is low, the smoke amount is less, and the smoke is not full. The utility model provides an electron atomizing device mixes above-mentioned two kinds of aerosols according to certain proportion, forms plump gentle and agreeable while the sweet and fragrant smog of taste, combines the advantage of two kinds of different particle diameter aerosols, improves the taste of smog.

Referring to fig. 3, fig. 3 is a schematic diagram of a separation interval between the particle size and the mouth feel of the aerosol, and through further study, when the particle size of the aerosol is located on the left side of the separation line in the diagram, that is, when the particle size of the aerosol is located in an interval of 0.01-2.7 μm, most of the aerosol particles will be deposited in the respiratory tract and alveoli of the human body when the aerosol enters the oral cavity of the human body, so that the human body feels dry and pure mouth feel. When the particle size of the aerosol is located at the right side of the separation line in the figure, namely the particle size of the aerosol is located in the interval of 2.7-mu m, most aerosol particles are deposited in the oral cavity of a human body, so that the human body can feel wet and sweet taste. When the proportion of the first aerosol to the second aerosol is different, the feeling of the human body is changed, so that the smog with different mouthfeel is formed.

Based on the relationship between the aerosol particle size and the taste, in this embodiment, the first average particle size ranges from 0.1 μm to 2 μm, and the second average particle size ranges from 30 μm to 50 μm, so that the smoke generated by the first aerosol generating unit 2 has a dry and clean taste, and the smoke generated by the second aerosol generating unit 3 has a moist and sweet taste. Because the values of the first average particle size and the second average particle size are relatively extreme, the mouthfeel is stronger, and the mouthfeel characteristics of the aerosol with the particle sizes can be better reflected.

The first aerosol in the present invention is generated by atomizing the aerosol-generating substrate in the atomized liquid storage chamber 1, and preferably, the first aerosol-generating unit 2 is a resistance atomizing device that heats and atomizes the aerosol-generating substrate to form the first aerosol. There are many ways in which the second aerosol can be formed, and two examples will be provided for specific description in this application.

The first embodiment is as follows:

the second aerosol in this embodiment is formed by atomisation of the second aerosol-generating unit 3, atomising the aerosol-generating substrate in the reservoir 1 to generate a second aerosol of a second average particle size. The second aerosol generating unit 3 is an ultrasonic atomizing device, and is atomized by ultrasonic screen hole vibration, and the second average particle size of the formed second aerosol is relatively large.

The working principle of the ultrasonic atomization device is that the ultrasonic vibration sheet drives the sieve pores to atomize liquid, and the particle size of aerosol formed by atomization is related to physical parameters (such as viscosity, surface tension and the like), vibration frequency and sieve pore diameter of a liquid medium. After the type of the atomized liquid is determined, the parameters such as viscosity, surface tension and the like are basically determined, and the vibration frequency and the mesh diameter of the ultrasonic atomization device are further controlled, so that the size of the particle diameter of the formed liquid drop can be determined, and a better aerosol generation effect is achieved.

The aerosol outlet of the resistance atomization device and the aerosol outlet of the ultrasonic atomization device are both communicated with the suction nozzle 4, so that the aerosol is mixed in the space of the suction nozzle 4 and reaches the oral cavity of a user through the suction nozzle 4.

The content ratio of the first aerosol and the second aerosol in each mixed smoke inhaled by a user determines the mouthfeel. The content ratio of the first aerosol and the second aerosol is adjusted, so that the smog with different mouthfeel can be formed. Therefore, a first drive device is provided in the first aerosol-generating unit 2, the first drive device being used to adjust the atomization power of the first aerosol-generating unit 2. A second drive device is provided in the second aerosol-generating unit 3 for adjusting the atomization power of the second aerosol-generating unit 3. The first driving device and the second driving device operate independently, and mixed smoke can be obtained by starting the first driving device and the second driving device simultaneously. When the power of the first driving device and the second driving device is adjusted, the atomization power of the first aerosol generating unit 2 and the atomization power of the second aerosol generating unit 3 are changed, so that mixed smoke containing the first aerosol and the second aerosol in different proportions is obtained, various tastes are combined, and users feel different experiences. The user can adjust first aerosol generating unit 2 and second aerosol generating unit 3 according to self demand, makes the mixed smog that certain specific electron atomizing device produced accord with self taste.

Referring to fig. 4, fig. 4 is a schematic view showing the particle size and mass of the aerosol formed by the resistance atomization device and the ultrasonic atomization device, and the particle size distributions of the first aerosol and the second aerosol formed by the resistance atomization device and the ultrasonic atomization device are as shown in fig. 4, the first average particle size of the first aerosol formed by the resistance atomization device is small, and the peak particle size of the mass distribution is concentrated on about 0.7 μm. The mouth feel of the cigarette is dry, clean and close to real cigarette after being sucked by an artificial article. The particle size of aerosol generated by optimizing the taper hole and the frequency of the ultrasonic atomization source is larger, and the peak value is concentrated at about 30 mu m, so that the second aerosol is easy to deposit in the oral cavity, and a moist, fragrant and sweet taste is formed.

Preferably, the aerosol-forming pore size of the ultrasonic atomizing device is set between 30-50 μm in order to form larger aerosol droplets.

Example two:

the second aerosol in this embodiment is formed by changing the particle size of a part of the first aerosol, and the second aerosol-generating unit 3 is a physical particle size-adjusting mechanism for changing a part of the first aerosol into a second aerosol of a second average particle size.

Referring to fig. 5, fig. 5 is a schematic structural diagram of another embodiment of the electronic atomization device of the present invention, in which the first aerosol generating unit 2 is a resistance atomization device, the second aerosol generating unit 3 is a physical particle size adjusting mechanism, a first aerosol discharge port of the resistance atomization device is directly communicated with the suction nozzle 4, a second aerosol discharge port of the resistance atomization device is directly communicated with the physical particle size adjusting mechanism, and an aerosol discharge port of the physical particle size adjusting mechanism is communicated with the suction nozzle 4. And part of the first aerosol discharged from the first aerosol discharge port enters a physical mode particle size adjusting structure, and the particle size of the first aerosol is changed through the physical mode particle size adjusting structure, so that the particle size of the part of the first aerosol is converted into a second average particle size from a first average particle size. The portion of the first aerosol is converted to a second aerosol as the particle size changes. And the second aerosol formed after conversion is mixed with the first aerosol discharged from the first aerosol discharge port to form mixed smoke containing aerosols with different particle sizes.

The physical mode particle size adjusting mechanism in this application includes ultrasonic vibration piece and sieve mesh, and the ultrasonic vibration piece drives the sieve mesh motion and makes the second aerosol of the collision reunion formation second average particle size of first aerosol. In this embodiment, the particle size of first aerosol is less than the second aerosol, and the supersound trembler drives the sieve mesh motion, and the first aerosol of small particle size is driven by the supersound trembler and is collided the reunion, and at this in-process, particle size increase after a plurality of first aerosols reunion forms the second aerosol, discharges to the outside through the sieve mesh.

The content ratio of the first aerosol and the second aerosol in each mixed smoke inhaled by a user determines the mouthfeel. The content ratio of the first aerosol and the second aerosol is adjusted, so that the smog with different mouthfeel can be formed. Therefore, a first drive device is provided in the first aerosol-generating unit 2, the first drive device being used to adjust the atomization power of the first aerosol-generating unit 2. A second driving device is provided in the second aerosol-generating unit 3, and the second driving device is used for adjusting the particle size adjusting power of the second aerosol-generating unit 3. The first driving device and the second driving device operate independently, and mixed smoke can be obtained by starting the first driving device and the second driving device simultaneously. When the powers of the first driving device and the second driving device are adjusted, the atomization power of the first aerosol generating unit 2 and the particle size adjusting power of the second aerosol generating unit 3 are changed, so that mixed smoke containing different proportions of the first aerosol and the second aerosol is obtained, and a user feels different tastes. The user can adjust first aerosol generating unit 2 and second aerosol generating unit 3 according to self demand, makes the mixed smog that certain specific electron atomizing device produced accord with self taste.

In the gas formed by mixing the first aerosol and the second aerosol, the content interval of the first aerosol is 1-20mg per mouth, and the content interval of the second aerosol is 1-10mg per mouth. In order to form mixed smoke suitable for most of the tastes of users, the first driving device and the second driving device are arranged in the embodiment, so that the working efficiency of the first aerosol generating unit 2 and the working efficiency of the second aerosol generating unit 3 are differentiated, and the contents of the first aerosol and the second aerosol generated by the electronic atomization device in the same time are different. On different electronic atomization devices, in each mouth of smoke inhaled by a user, the content interval of the first aerosol is 1-20mg, and the content interval of the second aerosol is 1-10mg, in one specific embodiment, the content of the first aerosol in each mouth of smoke inhaled by the user is 15mg, the content of the second aerosol is 8mg, at the moment, the content of the first aerosol is higher, and the mouth feel of the smoke felt by the user is drier, more comfortable and purer.
