Description

The application relates to the technical field of micropore atomization, in particular to an atomizer and an electronic atomization device.

Background

In recent years, microporous atomizing devices have been widely used for medical applications. The atomized medicine aerosol is inhaled from mouth and nose to enter trachea, bronchus and lung of patient, and the medicine is applied directly to the treated part to raise the medicine absorbing effect and effect efficiency and reduce the side effect of medicine.

The conventional microporous atomizing apparatus includes a chamber for storing a liquid medicine, and a microporous sheet, in which the liquid medicine is collected at one side of the microporous sheet, and the liquid medicine is atomized by the microporous sheet and then re-ejected from the other side. Generally, the microporous sheet is vibrated by ultrasonic high frequency to make the liquid medicine in the chamber flow to the microporous sheet through a liquid guide channel, and the liquid medicine is sprayed out from the tiny micropores of the microporous sheet to form aerosol.

However, when the outlet of the liquid guiding channel is too small, a large number of bubbles generated when the microporous sheet is ultrasonically vibrated at high frequency tend to accumulate on the side of the outlet of the liquid guiding channel, which results in isolation of the microporous sheet from the liquid discharged from the outlet of the liquid guiding channel and interruption of atomization. If the diameter of the outlet of the liquid guide channel is too large, when the aerosol generation substrate in the chamber is insufficient, the liquid level in the outlet of the liquid guide channel is lower than the microporous sheet, so that the liquid cannot be completely atomized, and the liquid remains in the chamber to nourish bacteria and even cause potential safety hazard.

Referring to fig. 1 to 4, an embodiment of the present application provides an atomizer 100, which includes a housing 10 and an atomizing assembly 50, wherein the housing 10 has a liquid guiding channel 11, the atomizing assembly 50 has an atomizing plate 51 disposed facing an outlet of the liquid guiding channel 11, and a geometric center of the atomizing plate 51 is offset from a geometric center of the outlet of the liquid guiding channel 11.

It will be understood that the geometric center of the atomizing plate 51 is offset from the geometric center of the outlet of the liquid guide passage 11. That is, the atomizing plate 51 is shifted to one side with respect to the outlet of the liquid guide passage 11 and is not located at the center thereof, so as to ensure that the geometric centers of the two are not on the same axis.

In this way, when sufficient aerosol-generating substrate is present in the liquid-conducting channel 11, the level of liquid in the outlet of the liquid-conducting channel 11 is high and the atomizing plate 51 is able to completely atomize the liquid. When aerosol in drain channel 11 generated the substrate not enough, liquid level in the drain channel 11 was lower this moment, because the setting of staggering of the geometric center of atomizing piece 51 and the outlet of drain channel 11, can operate this moment and generate one side that the substrate flows to the export and is close to atomizing piece 51 with aerosol and carry out the liquid down, atomizing piece 51 can atomize the aerosol generation substrate of low liquid level this moment, thereby guarantee also can realize when the liquid level is lower in the atomizing storehouse 12 being atomized, avoid breeding the bacterium that liquid remains the cause, installation hidden danger scheduling problem.

Moreover, at this time, the atomization condition of the atomization device is not interfered by the size of the outlet of the liquid guide channel 11, that is, complete atomization of the liquid can be ensured under various setting sizes of the outlet of the liquid guide channel 11.

In use, when the liquid level is low, the housing 10 may be rotated to cause the aerosol-generating substrate to be concentrated at the side of the opening where the edge of the opening is relatively close to the atomizing sheet 51 for liquid discharge, thereby ensuring that the aerosol-generating substrate can contact the atomizing sheet 51 to be atomized even if the liquid level is low, and achieving no liquid residue.

It will be appreciated that the liquid-conducting channel 11 serves to conduct aerosol-generating substrate to the side of the atomizing plate 51, and that the aerosol-generating substrate may be provided directly by the outer container or may be temporarily stored directly inside the housing 10. Referring to fig. 4, an atomization chamber 12 is provided inside the housing 10 and is in communication with the liquid guide channel 11, and a certain amount of aerosol-generating substrate is temporarily stored in the atomization chamber 12 for convenient use.

In one embodiment, referring to fig. 3, the outlet of the liquid guiding channel 11 and the atomizing plate 51 are both circular, and the atomizing plate 51 is radially and eccentrically arranged relative to the outlet of the liquid guiding channel 11, so that the conventional scheme that the atomizing plate 51 and the outlet of the liquid guiding channel 11 are concentrically arranged is avoided, and the projection of the atomizing plate 51 facing the outlet of the liquid guiding channel 11 at least covers a part of a fan-shaped area of the outlet, and the part forms an effective atomizing area, so that the liquid can be located in the effective atomizing area to be atomized regardless of the liquid level in the liquid guiding channel 11.

The circular liquid guide channel 11 is relatively beneficial to the flowing of liquid and is simple to process. It is understood that in other embodiments, the outlet of the liquid guiding channel 11 and the atomizing plate 51 may be configured in other shapes without limitation.

Further, the atomizing plate 51 is disposed radially eccentrically to one side with respect to the outlet of the liquid guide passage 11, and accordingly, a space between the atomizing plate 51 and the other side in the radial direction with respect to the outlet of the liquid guide passage 11 becomes large, forming an effective exhaust area. A large amount of bubbles generated when the atomizing sheet 51 atomizes the aerosol-generating substrate can be smoothly discharged through the effective exhaust area without being blocked, and smooth exhaust is ensured, so that continuous atomization is ensured, and the interruption of atomization caused by the blockage of the bubbles at the outlet of the liquid guide channel 11 is avoided.

In one embodiment, a mouthpiece is optionally mounted outside of the atomizing assembly 50 to facilitate inhalation of the aerosol gas by a user. Furthermore, the atomizing plate 51 may be ultrasonically vibrated at a high frequency to atomize the aerosol-generating substrate flowing out of the outlet of the liquid guide channel 11. The conventional heating wire, ceramic atomizing core and other resistance heating atomizing modes are avoided, aerosol generated from aerosol generated at the outlet of the liquid guide channel 11 is atomized at low temperature to generate aerosol, and meanwhile, bubbles are generated in a countercurrent mode, so that the atomization is safer and more environment-friendly.

Further, the geometric center of the outlet of the liquid guiding channel 11 is closer to the atomizing chamber 12 relative to the geometric center of the atomizing plate 51, that is, the atomizing plate 51 is eccentrically disposed relative to the liquid guiding channel 11 in the liquid discharging direction of the liquid in the liquid guiding channel 11. Thus, even if the liquid level in the liquid guide channel 11 is too low, the liquid can be collected at the lower side of the outlet for discharging, so that the liquid with the low liquid level can be effectively atomized.

In one embodiment, the geometric center of the atomizing plate 51 is a minimum distance c from the outlet edge of the liquid guiding channel 11, and the direction of the line of the minimum distance c is parallel to the gravity direction, so that the atomizing plate 51 moves downward relative to the liquid guiding channel in the direction parallel to the gravity direction, and sufficient atomization is ensured.

In particular, in some embodiments, the minimum distance c ranges from 1.5mm to 2.5mm, so as to avoid the position of the atomizing plate 51 being too low, and ensure that the lowest liquid level in the liquid guiding channel 11 is also within the effective atomizing area of the atomizing plate 51. On the other hand, the over-high position of the atomizing sheet 51 is avoided, the effective atomizing area is ensured to be closer to the edge of the outlet, and the liquid with low liquid level is effectively and fully atomized, so that the full atomization is realized.

Further, referring to fig. 5, a set of experimental data is provided, the abscissa being data of the minimum distance c in mm and the ordinate being the atomization rate of the atomizing plate 51 with respect to the liquid in the reservoir 11. As can be seen from the figure, when the minimum distance c is 0.5mm to 1.5mm, the atomization rate gradually increases until the minimum distance c is greater than 1.5mm, and the atomization rate gradually stabilizes. The minimum distance c needs to be set to not less than 1.5 mm.

Further, referring to fig. 6, a set of experimental data is provided, with the abscissa representing the data for the minimum distance c in mm and the ordinate representing the amount of drug remaining unaeromized (i.e., the remaining amount of liquid) after each atomization. As can be seen from the figure, when the minimum distance c is greater than 2.5mm, the amount of residual drug gradually increases. Therefore, the minimum distance c needs to be not more than 2.5mm, so that the high atomization rate is ensured on one hand, and the low residual medicine quantity is ensured on the other hand.

Specifically, in some embodiments, the geometric center of the atomizing plate 51 is a maximum distance d from the outlet edge of the liquid guide channel 11, the maximum distance d and the minimum distance c are located on the same straight line, the direction of the straight line where the maximum distance is located is opposite to the direction of gravity, and the maximum distance d is not less than 7mm, so that the effective exhaust area between the atomizing plate 51 and the outlet of the liquid guide channel 11 is large enough to ensure smooth exhaust.

Of course, in other embodiments, the effective air exhaust area may be open, in which case the atomizing plate 51 forms an effective atomizing area on the side opposite to the outlet of the liquid guiding channel 11, and the space on the other side may be freely set according to the structural requirement without being affected by the outlet edge of the liquid guiding channel 11.

Referring to fig. 7, a set of experimental data is provided, taking the diameter of the atomizing plate 51 as an example of 6mm, the abscissa is the diameter of the outlet of the liquid-conducting channel 11 in mm, and the ordinate is the atomizing rate of the atomizing plate 51 to the liquid in the liquid-conducting channel 11. Referring to fig. 8, another set of experimental data is provided, taking the diameter of the atomizing plate 51 as 6mm as an example, the abscissa is the diameter of the outlet of the liquid guiding channel 11 in mm, and the ordinate is the percentage of interruption of the atomization of the liquid in the liquid guiding channel 11 of the atomizing plate 51.

As can be seen from FIG. 7, the diameter of the outlet of the liquid guiding channel 11 is 4mm-7mm, and the atomization rate gradually increases until the diameter of the outlet of the liquid guiding channel 11 is larger than 7mm and then gradually stabilizes. As can be seen in FIG. 8, the data for the percentage of interruption of atomization decreases for a diameter of the exit of drainage channel 11 of 4mm to 7mm, and does not gradually stabilize and approach 0 until the diameter of the exit of drainage channel 11 is greater. Therefore, in order to ensure a high atomization rate and avoid the bubbles generated by the atomization of the atomizing plate 51 from blocking the outlet of the liquid guide channel 11 and interrupting the atomization, it is recommended that the size of the outlet 12 of the liquid guide channel 11 is not less than 8mm.

In summary, the diameter of the atomizing plate 51 can be set to 6mm, the diameter of the outlet of the liquid guiding channel 11 can be set to 9mm, the atomizing plate 51 is radially and eccentrically arranged relative to the outlet of the liquid guiding channel 11, the minimum distance c between the geometric center of the atomizing plate 51 and the outlet edge of the liquid guiding channel is set to 2mm, and the maximum distance d between the geometric center of the atomizing plate 51 and the outlet edge of the liquid guiding channel is set to 7mm.

In one embodiment, referring to fig. 9, the atomization apparatus further includes a liquid level detection assembly 20, the liquid level detection assembly 20 has a detection portion 21 communicated with the liquid guide channel 11, and the detection portion 21 is used for performing a low liquid level warning, for example, when the detection portion 21 extends into the liquid guide channel 11, if the detection portion 21 is completely separated from the liquid in the liquid guide channel 11, the liquid level detection assembly 20 issues a low liquid level warning, which indicates that the amount of aerosol-generating substrate in the liquid guide channel 11 is insufficient and needs to be replenished.

Whether the atomization operation needs to be performed is determined by determining whether or not liquid is present between the detection portion 21 and the atomization sheet 51. When liquid exists between the atomizing sheet 51 and the detecting part 21 and the liquid level of the outlet of the liquid guide channel 11 is higher than the effective atomizing area of the atomizing sheet 51, it is determined that the liquid exists in the liquid guide channel 11 and the atomization is normally performed. When the amount of liquid between the atomizing plate 51 and the detecting part 21 is too small and the liquid level at the outlet of the liquid guiding channel 11 is lower than the effective atomizing area of the atomizing plate 51, it is determined that the liquid in the atomizing chamber 12 is insufficient, atomization is stopped, and an early warning is given to remind a user of liquid supplement.

Thus, the atomization device has smooth exhaust, small liquid residual quantity and normal water level detection work.

In one embodiment, the liquid level detecting assembly 20 may be a water level detecting probe, and the detecting portion 21 is a needle of the water level detecting probe, and the water level detecting probe determines the liquid level in the liquid guiding channel 11 by detecting a resistance value between the water level detecting probe and the atomizing plate 51. When at least part of the needle is immersed in the liquid guiding channel 11, the resistance between the detection probe and the atomizing plate 51 is relatively low due to the conductive effect of the liquid; at this time, the liquid is enough and the liquid level is safe. When the needle head is completely separated from the liquid in the liquid guide channel 11, the liquid is not used as a conductor at this time, and the resistance value between the detection probe and the atomizing plate 51 is large; the liquid is lack at this moment, and the liquid level is crossed lowly, and water level detection probe sends low liquid level early warning this moment, reminds the user through warning light or the mode of warning vibration.

It can be understood that when the aerosol-generating substrate is water, the liquid level in the liquid guiding channel 11 is sufficient and the resistance change is large only when a layer of water film adheres to the inner wall of the liquid guiding channel 11, and at this time, the judgment can be made by the early warning of the liquid level detecting assembly 20. However, when the aerosol-generating substrate is other liquids such as physiological saline, the liquid level in the liquid guiding channel 11 is sufficient, and the resistance change is small when only one layer of water film adheres to the inner wall of the liquid guiding channel 11, and the liquid level cannot be determined by the early warning of the liquid level detecting assembly 20. This application is through the introduction of partition 30, avoids leading the formation of water film on the inner wall of liquid channel 11 to guarantee that the liquid level of liquid level detection subassembly 20 judges the accuracy, can guarantee simultaneously that the atomizer 100 that this application provided can be applicable to the aerosol generation substrate of multiple difference. It is understood that in other embodiments, the resistance signal between the detection probe and the atomization plate 51 can be converted into a voltage signal between the detection probe and the atomization plate 51 for determining whether there is a liquid shortage.

In order to solve the above problem, referring to fig. 9 and 10, the atomization device provided in the present application further includes a partition 30, where the partition 30 is disposed between the detection portion 21 and the atomization plate 51 to partition the liquid adhered to the inner wall of the liquid guide channel 11 between the detection portion 21 and the atomization plate 51, so that the liquid in the liquid guide channel 11 flows to the partition 30, and is unable to flow to the inner wall of the partition 30 to form a complete water film, thereby avoiding a misjudgment phenomenon that the detection portion 21 does not issue a low liquid level warning when the liquid level in the liquid guide channel 11 is too low and the water film formed on the inner wall causes the detection portion 21 to not issue a low liquid level warning, eliminating an influence of the water film adhered to the liquid guide channel 11 on the detection portion 21 on the water level detection, and improving the detection accuracy.

It will be appreciated that the cohesion of the liquid makes it resistant to tensile attraction and the adsorption of the liquid makes it adhere to the inner wall of the liquid-conducting channel 11 due to its cohesion and adsorption. So that a complete water film is easily formed on the inner wall of the liquid guide channel 11. And after the water film is formed, the water film is not easy to be damaged in a stable state due to the action of surface tension. This application forms an exogenic action through partition member 30, acts on the liquid that is just flowing along drain channel 11's inner wall, destroys its adsorption affinity and surface tension, makes it produce when flowing to partition member 30 position and cuts off the flow, and the liquid that is stained with on the drain channel 11 inner wall at this moment can't form a complete water film to the water film that has formed on the inner wall has been avoided and has been leaded to the erroneous judgement phenomenon that detection portion 21 did not send low liquid level early warning.

In one embodiment, the partition 30 includes a partition 31, the partition 31 is protrudingly disposed on the inner wall of the liquid guiding channel 11 and located between the detecting portion 21 and the atomizing plate 51, when the liquid adhered on the inner wall of the liquid guiding channel 11 spreads to the atomizing plate 51 side along the inner wall, the liquid needs to "climb" and then "fall" when flowing through the partition 31, and during the climbing and falling, the adsorption force and surface tension of the liquid are destroyed, thereby generating the flow interruption.

Further, referring to fig. 10, the blocking portion 31 has a blocking sharp corner 33 protruding between the detecting portion 21 and the atomizing plate 51, and the blocking sharp corner 33 is a non-obtuse angle, so that when the liquid adhered to the inner wall of the liquid guiding channel 11 flows through the blocking sharp corner 33, the point of the blocking sharp corner 33 generates a cutting-like acting force, so that the liquid is blocked, and the liquid is prevented from adhering to the inner wall in a sheet form to form a complete water film.

Further, it is preferable to set the blocking sharp angle 33 to be an acute angle so that the blocking sharp angle 33 is sufficiently "sharp" and the cutting force is sufficiently large to ensure effective blocking of the water film attached to the inner wall of the drainage channel 11.

Further, referring to fig. 9 and 10, the partition 30 further includes a flow guide portion 32, and the flow guide portion 32 is disposed between the partition 31 and the atomizing plate 51 along the flowing direction of the liquid. The liquid flowing to the atomizing plate 51 passes through the partition 31 and then flows to the atomizing plate 51 side under the guidance of the flow guide 32. Along the flow direction of liquid, form the obtuse angle contained angle between water conservancy diversion portion 32 and the inner wall of drain channel 11 to guarantee that the liquid after flowing through wall portion 31 can flow away fast, thereby avoid producing the hydrops between wall portion 31 and the water conservancy diversion portion 32 and produce the refluence, lead to the phenomenon that the water film that will be cut off reconnects again.

In one embodiment, referring to fig. 9, the atomizer 100 further comprises an auxiliary element 40, the auxiliary element 40 has a first space 41 communicated with the opening of the liquid guiding channel 11, the auxiliary element 40 is disposed in the liquid storage cavity and has one end connected to the inner wall of the liquid guiding channel 11. The liquid level detection assembly 20 is assembled in the first space 41 and the detection part 21 extends into the liquid guide channel 11.

Through the setting of auxiliary member 40, provide the installation basis for the assembly of liquid level detection subassembly 20, make it can be stable be fixed in drain channel 11 and carry out the liquid level detection.

In addition, the detection part 21 extends into the liquid guide channel 11, so that the low liquid level defined by the liquid level detection assembly 20 cannot be too high, and frequent reminding of the liquid level detection assembly 20 is avoided.

In one embodiment, the portion of the liquid level detection assembly 20 that is fitted in the first space 41 is hollow, so that gas can supplement pressure along the first space 41 in a reverse flow manner while liquid flows toward the atomization sheet 51, thereby preventing negative pressure from being generated at the inlet during liquid consumption and affecting the normal flow of liquid.

In one embodiment, the auxiliary element 40 further has a first space 41 communicating with the liquid guiding channel 11, and the liquid in the outer container or the atomization chamber 12 flows into the liquid guiding channel 11 through a second space 42. In this way, liquid can be replenished into the liquid guide passage 11 through the second space 42.

Further, the first space 41 and the second space 42 are provided with the same extending direction, the auxiliary member 40 can be provided as a hollow round pipe structure, one end of the round pipe extends out of the casing 10 to form a liquid injection port, and the other end is communicated with the liquid guide channel 11.

According to another aspect of the present application, there is provided an electronic atomizer apparatus including the atomizer 100 described in any one of the embodiments above. The atomizing plate 51 of the atomizing assembly 50 is used to atomize the aerosol-generating substrate to form an aerosol for inhalation by a user.

The application provides an electronic atomization device, through the setting of staggering with the geometric centre of the export of the geometric centre of atomizing piece 51 and drain channel 11, make when aerosol generation matrix in the drain channel 11 is not enough, liquid level in the drain channel 11 is lower this moment, because the setting of staggering with the geometric centre of the export of drain channel 11 of atomizing piece 51, can operate this moment and generate the one side that the matrix flows to the export and is close to atomizing piece 51 with aerosol and carry out the time drain, atomizing piece 51 can atomize the aerosol generation matrix of low liquid level this moment, thereby also can realize being atomized when guaranteeing that the liquid level is lower in the atomizing storehouse 12, avoid breeding the bacterium that liquid remains the cause, installation hidden danger scheduling problem.

Moreover, at this time, the atomization condition of the atomization device is not interfered by the size of the outlet of the liquid guide channel 11, that is, complete atomization of the liquid can be ensured under various setting sizes of the outlet of the liquid guide channel 11.
