The inventor of the present application has found through research that the reason why the conventional atomizer is difficult to suck is that: in traditional atomizer, the atomizer includes the casing and locates on the casing and air inlet and the gas outlet that set up perpendicularly each other, and the air current gets into in the casing from the air inlet, takes away the aerosol in the atomizing district in the casing, flows from the gas outlet, and this in-process air current flow direction can take place to change by a wide margin before getting into the atomizing district, and very easily produce the vortex and cause the energy loss of air current great, leads to the resistance of sucking the in-process great, and then leads to traditional atomizer to suck comparatively difficultly.
In order to solve the comparatively difficult problem of traditional atomizer suction, this application has designed an atomizer, and the atomizer includes air inlet channel and the atomizing district that communicates each other, makes the air current that flows in from the air inlet along air inlet channel's lateral wall flow through the design to stepwise adjust the direction and flow to the atomizing district, avoid the air current to flow the direction and can take place to change by a wide margin before getting into the atomizing district, reduce the production of vortex, make the energy loss of air current less, can inhale the aerosol that this air current carried more easily.
Fig. 1 shows a schematic structural view of an atomizer 10 in an embodiment of the present application.
Referring to fig. 1 in combination with fig. 2, an atomizer 10 according to an embodiment of the present disclosure includes a housing 110, wherein the housing 110 is provided with an air inlet 111 and an air outlet 112 facing different directions, and an air flow passage communicating between the air inlet 111 and the air outlet 112.
The air flow passage includes an air intake passage 113 and an atomization zone 114 communicating with each other, it being understood that an end of the air intake passage 113 remote from the atomization zone 114 communicates with the air intake port 111, and an end of the atomization zone 114 remote from the air intake passage 113 communicates with the air outlet port 112.
The air flow flows into the air inlet channel 113 from the air inlet 111, and the air inlet channel 113 is configured to extend from one end close to the air inlet 111 to one end close to the atomization zone 114 in a bending manner, so that the air flow flowing in from the air inlet 111 can flow along the side wall of the air inlet channel 113, gradually adjust the direction and flow towards the atomization zone 114, the air flow is prevented from being changed greatly before entering the atomization zone 114, the generation of vortex flow can be reduced, the energy loss of the air flow is small, the air flow is facilitated to flow from the atomization zone 114 towards the air outlet 112, aerosol at the side wall of the atomization zone 114 is taken away, and the air flow resistance is small, so that the aerosol can be sucked more easily.
In some embodiments, the air intake passage 113 is configured to curve arcuately from an end proximate to the air intake 111 to an end proximate to the atomization zone 114.
It will be appreciated that the side wall of the air inlet channel 113 extends in an arc-shaped manner, so that the air flow entering the air inlet channel 113 can well flow along the side wall of the air inlet channel 113, that is, the side wall of the air inlet channel 113 can guide the air flow to gradually adjust the flowing direction, the generation of vortex is well reduced, the energy loss of the air flow is smaller, and aerosol can be absorbed more easily.
In some embodiments, referring to fig. 2 and 3, the air inlet channel 113 includes a first channel 1131 having one end communicating with the air inlet 111, a second channel 1132 having one end communicating with the atomization zone 114 and extending along the axial direction of the atomization zone 114, and an arc-shaped channel 1133 communicating between the first channel 1131 and the second channel 1132.
By using the arc-shaped channel 1133, the airflow entering the first channel 1131 can gradually change the flowing direction when passing through the arc-shaped channel 1133, by using the second channel 1132 extending along the axis direction of the atomization area 114, the airflow entering the second channel 1132 can flow to the atomization area 114 approximately along the axis direction of the atomization area 114, and by using the arc-shaped channel 1133 to form arc transition, the generation of vortex can be reduced, the energy loss of the airflow is smaller, the carrying capacity of the airflow to aerosol can be improved, and the sucking effect can also be improved.
In some embodiments, the first channel 1131 has a first communication port 11311 that communicates with the arcuate channel 1133, and the flow area of the inlet 111 is greater than the flow area of the first communication port 11311.
In this way, in the process that the air flow entering the first channel 1131 through the air inlet 111 flows to the first communication port 11311, there is a deceleration process, so that the air flow can flow relatively smoothly to the first communication port 11311, which is more beneficial to reducing the generation of vortex, reducing the energy loss of the air flow, and further improving the sucking effect and the carrying capacity of the air flow to aerosol.
In some embodiments, the air inlet 111 extends arcuately around the first communication port 11311.
It is appreciated that the front projection of the first channel 1131 onto the bottom end of the housing 110 is generally fan-shaped (as can be appreciated in connection with fig. 4).
Under the condition that the occupied volume of the housing 110 is not increased, the air inlet 111 is curved and extended in an arc shape around the first communication port 11311, so that the flow area of the air inlet 111 is increased, the air flow entering the air inlet 111 can flow towards the first communication port 11311 along the radial direction of the air inlet 111, can flow to the first communication port 11311, gradually changes the flow direction of the air flow through the arc-shaped channel 1133, and finally flows to the atomization area 114, so that on one hand, the air inflow can be increased, the aerosol generated at the side wall of the atomization area 114 can be timely taken away, the carrying capacity of the air flow to the aerosol can be improved, on the other hand, the energy loss of the air flow is smaller, and the sucking effect is better.
In some embodiments, referring to fig. 3, the air inlet 111 has an arcuate edge 1111, the center of the arcuate edge 1111 coinciding with the central axis of the atomizing area 114.
It will be appreciated that the air inlet 111 extends arcuately around the centre line of the atomising region 114.
The air flow entering the air inlet channel 113 through the air inlet 111 can gradually change direction and flow to the atomization area 114, and can timely carry away the aerosol generated at the side wall of the atomization area 114, and as the circle center of the arc-shaped edge 1111 coincides with the central line of the atomization area 114, the air flow and the aerosol carried by the air flow can gradually get close to the center of the atomization area 114 in the process of flowing from the atomization area 114 to the air outlet 112, thereby being more beneficial to conveying the aerosol to the air outlet 112.
In this embodiment, the side wall of the first channel 1131 includes a radial extension extending in the radial direction of the arcuate edge 1111 to facilitate the flow of air converging along the radial extension to the first communication port 11311.
In some embodiments, referring to fig. 2, the second channel 1132 has a first side wall 11321, and the atomizing area 114 has a second side wall 1141 extending along the extending direction of the first side wall 11321, and the second side wall 1141 is flush with the first side wall 11321.
Because the second side wall 1141 continues to extend along the extending direction of the first side wall 11321 and is flush with the first side wall 11321, the air flow flowing to the atomization area 114 along the axis direction of the atomization area 114 through the second channel 1132 can flow along the first side wall 11321 and continue to flow along the second side wall 1141, which is beneficial to the air flow to take away the aerosol generated at the side wall of the atomization area 114, reduces the energy loss of the air flow, and can improve the carrying capacity of the air flow to the aerosol and improve the sucking effect.
In some embodiments, referring to fig. 2, an end of the air inlet channel 113 near the atomization region 114 has a second communication port 11322 communicating with the atomization region 114, and the second communication port 11322 is closer to a sidewall of the atomization region 114 than a central axis of the atomization region 114 along a radial direction of the atomization region 114.
It is understood that the second communication port 11322 is disposed at an end of the second channel 1132 remote from the arc-shaped channel 1133.
In this way, the second communication port 11322 is close to the side wall of the atomization area 114, so that the air flow entering the air inlet channel 113 can better contact with the aerosol generated at the side wall of the atomization area 114 after entering the atomization area 114, and timely take away the aerosol generated at the side wall of the atomization area 114, thereby being beneficial to improving the carrying capacity of the air flow to the aerosol, enhancing the heat exchange of the wall surface, avoiding the local high temperature generation of carbon deposition and scorched smell, and improving the sucking concentration of the aerosol.
In some embodiments, the central axis of the second communication port 11322 and the central axis of the atomization zone 114 are parallel to each other, the cross-sectional shape of the second communication port 11322 is circular, and the cross-sectional shape of the atomization zone 114 is circular.
The contact area between the airflow and the side wall of the second communication port 11322 and between the airflow and the side wall of the atomization zone 114 can be increased, so that the aerosol generated at the side wall of the atomization zone 114 can be better taken away, and the carrying capacity of the airflow to the aerosol can be improved.
In some embodiments, the radial dimension of the second communication port 11322 is less than the radial dimension of the atomization zone 114.
In this way, the air flow in the air inlet channel 113 enters the atomization zone 114 with a larger caliber through the second communication port 11322 with a smaller caliber, a speed increasing process can occur, and the second communication port 11322 is combined to be closer to the side wall of the atomization zone 114 along the radial direction of the atomization zone 114, so that the air flow can more rapidly take away the aerosol generated at the side wall of the atomization zone 114, the local high temperature is avoided from generating carbon deposition and coke smell, and the carrying capacity of the air flow on the aerosol is also more beneficial to be improved.
In some embodiments, the second communication port 11322 is spaced a from the central axis of the atomizing area 114 in the radial direction of the atomizing area 114, the second communication port 11322 has a radial dimension B, and a is greater than or equal to B.
If a is equal to B, the second communication port 11322 is not only closer to the sidewall of the atomization area 114 along the radial direction of the atomization area 114, but also the flow area of the second communication port 11322 is ensured, which is beneficial to improving the carrying capacity of the airflow to the aerosol.
If a is greater than B, the second communication port 11322 is closer to the sidewall of the atomization region 114 along the radial direction of the atomization region 114, which is more beneficial to improving the carrying capacity of the airflow to the aerosol.
In some embodiments, the central axis of the air outlet 112 and the central axis of the atomization zone 114 coincide with each other.
So arranged, the airflow in the atomizing area 114 and the aerosol carried by the airflow are more advantageously delivered to the air outlet 112.
In some embodiments, the housing 110 is further provided with an exhaust passage 115 communicating between the atomizing area 114 and the air outlet 112, the radial dimension of the exhaust passage 115 being greater than the radial dimension of the atomizing area 114.
With this arrangement, the airflow flowing from the atomization area 114 to the exhaust passage 115 presents a speed increasing process, which is more beneficial to the airflow in the atomization area 114 and the aerosol carried by the airflow to be conveyed to the air outlet 112.
In some embodiments, the exhaust channel 115 includes an outlet section proximate the air outlet 112, with the radial dimension of the outlet section of the exhaust channel 115 gradually increasing in the direction of the atomizing area 114 toward the air outlet 112.
It is advantageous to increase the speed of the outward flow of the air flow in the outlet section of the exhaust channel 115 so that the user can better inhale the aerosol at the air outlet 112.
In some embodiments, the airflow channel includes at least two air inlet channels 113 spaced about a central axis of the atomization zone 114, the atomization zone 114 being in communication with the second communication port 11322 of each air inlet channel 113, respectively.
The air flow can flow into the atomization zone 114 through the air inlet channels 113 respectively, and aerosol generated at the side wall of the atomization zone 114 can be taken away in time while the air inflow is increased, so that the carrying capacity of the air flow to the aerosol is higher.
In some embodiments, the air inlet 111 has a preset flow area S.
If the flow area of the air inlet 111 is too small, the air intake amount and the sucking effect of the atomizer 10 will be affected, and if the flow area of the air inlet 111 is too large, the air flow will be too close to the air outlet 112 when the air flow is collected at the center of the flow channel at a preset flow rate, which is not beneficial to earlier collection of aerosol. Therefore, the air inlet 111 needs to have a preset flow area S, so that on one hand, the flow area of the air inlet 111 can be increased to increase the air intake amount, and on the other hand, the concentration of the aerosol can be increased due to the earlier accumulation of the aerosol.
In some embodiments, the preset flow area S is satisfied toThe following conditions were: 3.54mm 2 ≤S≤7.07mm 2 。
Illustratively, the air inlet 111 extends in an arc-like curve around the central axis of the atomization zone 114, the central angle α of the arc-shaped edge 1111 of the air inlet 111 takes 30 °, 60 °, 90 °, 120 ° and 150 ° (the central angle α of the arc-shaped edge 1111 can be understood in conjunction with fig. 4), the dimension of the air inlet 111 in the axial direction of the atomization zone 114 is a (can be understood in conjunction with fig. 5), the radial dimension of the atomization zone 114 is 2R (can be understood in conjunction with fig. 5), the ratio of a to R is 0.5, R is 1.3mm, the distance between the air inlet 111 and the central axis of the atomization zone 114 in the radial direction of the atomization zone 114 is R (can be understood in conjunction with fig. 5), R is 2.6mm, the flow rate of the air outlet 112 is constantly 18.3ml/s, the inlet relative pressure is 0Pa, and the air pressure is consistent. As can be seen from table 1 below, as the central angle of the arc-shaped edge 1111 increases gradually, the flow area of the air inlet 111 increases gradually, but the position Z along the axis direction of the atomizing area 114 increases gradually when the air flow is concentrated at the center of the flow channel (the flow channel includes the atomizing area 114 and the exhaust passage 115) at the preset flow rate, which results in too close distance from the air outlet 112 when the air flow is concentrated at the center of the flow channel at the preset flow rate, which is disadvantageous for earlier concentration of aerosol.
Therefore, the central angle α of the arc-shaped edge 1111 may be set to 60 ° or more and 120 ° or less, and the preset flow area S may be set to satisfy the following conditions: 3.54mm 2 ≤S≤7.07mm 2 Therefore, the air inflow can be improved, and the earlier aggregation of the aerosol is facilitated, so that the concentration of the aerosol is improved, and a better sucking effect can be achieved.
Table 1 a list of flow areas and Z of the inlet 111 in the case of different values of the central angle α of the arcuate edge 1111
In some embodiments, the dimension of the air inlet 111 along the axial direction of the atomizing area 114 is a, the radial dimension of the atomizing area 114 is 2r, and the ratio of a to r is a preset value b.
The ratio of a to r is too small, so that the earlier aggregation of the aerosol is not facilitated, and the carrying capacity of the airflow to the aerosol is influenced due to the fact that the ratio of a to r is too large.
In some embodiments, the preset value b satisfies the following condition: b is more than or equal to 0.3 and less than or equal to 0.5.
Illustratively, b is 0.2, 0.3, 0.4, 0.5, and 0.6, respectively, the central angle α of the arcuate edge 1111 may be set to 60 °, r is 1.3mm, r is 2.6mm, the flow rate at the air outlet 112 is constant at 18.3ml/s, and the inlet relative pressure is 0Pa, consistent with atmospheric pressure. As can be seen from table 2, when the preset value b is gradually increased, the position Z along the axis direction of the atomizing area 114 when the airflow is collected at the center of the flow channel at the preset flow rate gradually decreases, that is, the farther the airflow is collected at the center of the flow channel from the air outlet 112 at the preset flow rate, the earlier the concentration of the aerosol is more beneficial to the collection of the aerosol, so that the concentration of the aerosol can be increased, but the radial distance between the high-speed area of the airflow and the side wall of the atomizing area 114 along the atomizing area 114 gradually increases, so that the carrying capacity of the airflow to the aerosol can be reduced. Therefore, the preset value b needs to satisfy the following conditions: b is more than or equal to 0.3 and less than or equal to 0.5, so that the carrying capacity of air flow to aerosol is not influenced, the concentration of the aerosol can be increased, and a better sucking effect is achieved.
TABLE 2A list of distances along the radial direction of the atomizing area 114 between the high velocity region of the Z and the gas stream and the sidewall of the atomizing area 114 for different values of the ratio of a to r
In some embodiments, referring to fig. 6, a heating element 120 is disposed in the housing 110, the atomizing area 114 is formed on an inner wall of the heating element 120, a liquid storage cavity 130 for accommodating aerosol matrix is defined between an outer wall of the heating element 120 and the inner wall of the housing 110, the heating element 120 is configured to receive the aerosol matrix in the liquid storage cavity 130 and atomize the received aerosol matrix in the atomizing area 114, that is, the heating element 120 atomizes the aerosol matrix to form aerosol, and the aerosol can be generated at a side wall of the atomizing area 114.
After the air flow enters the corresponding air inlet channel 113 through the air inlet 111, the air flow can well flow along the side wall of the air inlet channel 113, vortex is not easy to generate, energy loss is extremely low, and after the air flow enters the atomization zone 114 with a larger caliber from the first communication port 11311 with a smaller caliber, the air flow can rapidly pass through the side wall of the atomization zone 114, so that a high-speed zone formed by the air flow can be concentrated at the side wall of the atomization zone 114, that is, the high-speed zone formed by the air flow can be concentrated at the area for generating the aerosol, and the aerosol generated by atomization is timely taken away.
In some embodiments, the airflow channel includes two air inlet channels 113 symmetrically arranged with respect to a central axis of the atomizing area 114, and the preset flow area S satisfies the following condition: 3.54mm 2 ≤S≤7.07mm 2 And the preset value b satisfies the following condition: b is more than or equal to 0.3 and less than or equal to 0.5. For example, arcuate edge 1111 has a central angle α of 60 °, and a predetermined flow area S of 3.54mm 2 B is 0.5 respectively, the central angle alpha of the arc edge 1111 can be set to be 60 degrees, r is 1.3mm, R is 2.6mm, the flow of the air outlet 112 is constant to be 18.3ml/s, the inlet relative pressure is 0Pa, and the air outlet is consistent with the atmospheric pressure.
Fig. 7 shows velocity distribution diagrams of the air flow, fig. 8 shows a graph of sectional velocity distribution data of the air flow (4 sections are selected in the direction of the central axis of the atomizing area 114, and the coordinates of the 4 sections in the direction of the central axis of the atomizing area 114 are z=0, z=0.2, z=0.4, and z=0.6, respectively), and as can be seen from fig. 7 and 8, the atomizer 10 can flow along the streamline wall surface of the air inlet channel 113 before the air flow enters the atomizing area 114 by using the coanda effect in aerodynamic, is not easy to generate vortex, and has little energy loss. In fig. 8, the abscissa represents the distance between the air flow and the side wall of the atomization area 114 along the radial direction of the atomization area 114, the ordinate represents the speed of the air flow, obviously, the high-speed area of the air flow is concentrated at a position 1mm away from the center of the atomization area 114, and as the combination r is 1.3mm, the high-speed area of the air flow is concentrated near the side wall of the atomization area 114, so that after the air flow enters the atomization area 114, the high-speed area of the air flow is concentrated near the side wall of the atomization area 114, the air flow is beneficial to timely taking away the aerosol generated by atomization, and the high-speed area of the air flow gradually gathers towards the center of the exhaust channel 115 along with the gradual flow of the air flow towards the air outlet 112, on one hand, the air flow is beneficial to conveying the aerosol towards the air outlet 112, and on the other hand, the high-speed air flow can timely take away the heat of the atomization area 114, and the local excessive temperature is avoided to generate carbon deposition and coke smell.
