Atomizing core and be equipped with its atomizing device

Technical Field

The utility model relates to an atomizing technical field especially relates to an atomizing core and be equipped with its atomizing device.

Background

An aerosol is a colloidal dispersion system formed by dispersing small solid or liquid particles in a gaseous medium, and since the aerosol can be absorbed by the human body through the respiratory system, an atomizing device that generates an aerosol by heating an aerosol-generating substrate such as medical liquid or electronic cigarette liquid is used in various fields such as medical treatment and tobacco substitute products, and delivers the aerosol for inhalation to a user.

In order to allow the air flow to flow in the atomizing device to carry away the aerosol generated by atomizing the atomized liquid, an air flow channel is usually provided in the atomizing device, and the outside air enters the atomizing device through the air flow channel and then flows through the heating component to carry away the aerosol generated by the heating component. At present, the common air intake mode of the air flow channel in the atomization device adopts a bottom air intake mode and a side air intake mode.

The bottom of the atomizing device adopting the bottom air inlet mode is provided with a bottom air inlet, and the bottom air inlet is over against the lower surface of the heating body. When a user sucks the atomizing device, external air flow directly impacts the lower surface of the heating body after entering the atomizing device through the bottom air inlet hole, and then aerosol generated by atomization is taken out of the atomizing device. The inventor discovers in research that the atomized liquid stored on one side of the heating body is easy to leak through the bottom air inlet hole because the bottom air inlet hole directly faces to the lower surface of the heating body, thereby influencing the use experience of the atomization device.

And the lateral side of the atomizing device adopting the lateral air inlet mode is provided with a lateral side air inlet, and the lateral side air inlet is over against the lateral side of the heating body. When a user sucks the atomizing device, external air flow enters the atomizing device through the side air inlet hole and then reaches the heating body through the inner cavity of the atomizing device, and aerosol generated by atomization is taken out of the atomizer. The inventors have found that, in the side air intake method, although leakage of the atomized liquid can be prevented to some extent, the temperature of the surface of the heating element cannot be rapidly lowered due to the long flow path and the slow flow rate of the side air intake airflow, which affects the taste of the aerosol generated by atomization, and further affects the use experience of the atomization apparatus.

Referring to fig. 1 to 3, an embodiment of the present invention provides an atomizing device, which includes an atomizing core 100 and a power supply assembly connected to one end of the atomizing core 100, wherein the power supply assembly is used for supplying power to the atomizing core 100, and the atomizing core 100 is used for storing and heating atomized liquid, so that the atomized liquid is atomized to form aerosol for a user to inhale. Can be connected, and the specific structure of the power supply assembly is not described herein since the structure of the power supply assembly does not belong to the main invention point of the present invention.

The atomizing core 100 includes a base 10, a sealing seat 30, a heating element 50, an air outlet rod 60 and a liquid storage tube 72, the base 10, the sealing seat 30, the heating element 50, the air outlet rod 60 and the liquid storage tube 72 define an air flow channel allowing air flow to flow through, and the air flow entering the air flow channel can take away the aerosol generated by heating the atomized liquid by the heating element 50.

Specifically, the base 10 is provided with an air outlet channel 61 communicated with the external environment, a first intermediate air passage cavity 20 communicated with the air outlet channel 61 is defined between the sealing seat 30 and the base 10, a second intermediate air passage cavity 40 communicated with the first intermediate air passage cavity 20 is defined between the sealing seat 30 and the heating element 50, and the air outlet rod 60 is connected to the heating element 50 in a matching mode and forms the air outlet channel 61 communicated with the second intermediate air passage cavity 40. In this way, air outlet channel 61, first intermediate air duct cavity 20, second intermediate air duct cavity 40 and air outlet channel 61 are communicated with each other to form a complete air flow channel.

Above-mentioned atomizing core 100, the setting of seal receptacle 30 has formed the first middle air flue chamber 20 and the second middle air flue chamber 40 of intercommunication each other in its both sides to form a double-deck airflow channel, kept apart inlet channel 121 and outlet channel 61, consequently can prevent that the atomizing liquid from the inlet channel 121 of outlet channel 61 inflow, and then effectively avoid atomizing core 100 to take place the atomizing liquid and leak in the use. Moreover, since the air inlet channel 121 is opened on the base 12, the atomizing core 100 has a higher flow speed of the air flow compared to the side air inlet in the prior art, and thus the cooling rate of the heating element 50 is not increased.

Referring to fig. 1 to fig. 3, the base 10 has a cylindrical structure with an opening at one end, and includes a base bottom wall 12 and a base side wall 14, wherein the thickness direction of the base bottom wall 12 is a first direction, the length direction of the base bottom wall 12 is a second direction, and the base side wall 14 extends from the edge of the base bottom wall 12 toward the same side of the base bottom wall 12 along the first direction and circumferentially surrounds the base bottom wall 12. Air inlet channel 121 and two first electrode mounting holes 123 are formed in base bottom wall 12, air inlet channel 121 and first electrode mounting holes 123 penetrate through base bottom wall 12 along a first direction, air inlet channel 121 is located at the center of base bottom wall 12, and two first electrode mounting holes 123 are located on two opposite sides of air inlet channel 121 in the first direction respectively. The side of the base sidewall 14 away from the base bottom wall 12 is provided with two mounting protrusions 16, the two mounting protrusions 16 are disposed on two opposite sides of the base sidewall 14 at an interval in the second direction, and the mounting protrusions 16 are adapted to mate with the sealing seat 30.

The seal receptacle 30 includes seal receptacle diapire 32 and seal receptacle lateral wall 34, and the thickness direction of seal receptacle diapire 32 extends along the first direction, and the length direction of seal receptacle diapire 32 extends along the second direction, and seal receptacle lateral wall 34 extends and encircles seal receptacle diapire 32 along circumference respectively towards the both sides of seal receptacle diapire 32 from the edge of seal receptacle diapire 32 along the first direction, and seal receptacle lateral wall 34 offers the protruding 16 complex mounting groove of installation with base 10 towards one side of base 10. The seal receptacle is sleeved on one side of the base 10, the seal receptacle side wall 34 is in interference fit with the base side wall 14, the mounting protrusion 16 of the base 10 is inserted into the mounting groove of the seal receptacle side wall 34, and the seal receptacle bottom wall 32 and the base bottom wall 12 are spaced in the first direction to define a first middle air passage cavity 20 communicating with the air inlet passage 121.

Further, the seal seat bottom wall 32 is opened with a seal seat air inlet hole 321, the seal seat air inlet hole 321 penetrates through the seal seat bottom wall 32 along the first direction to communicate with the first middle air passage cavity 20, a second electrode mounting hole 323 is further opened on one side of the seal seat bottom wall 32 facing the base 10, and two second electrode mounting holes 323 are respectively disposed on two opposite sides of the seal seat air inlet hole 321 in the second direction. Thus, the air flow flowing in from the air inlet passage 121 enters the first intermediate air passage chamber 20 and then flows out through the seal holder air inlet holes 321, and the electrode 80 protruding out of the base 10 protrudes into the second electrode mounting hole 323.

Preferably, in some embodiments, the seal seat bottom wall 32 defines two seal seat air inlet holes 321, and the two seal seat air inlet holes 321 are spaced apart in the second direction. In this way, the two seal seat air inlet holes 321 are on two sides of the first middle air passage cavity 20, and the air flow in the first middle air passage cavity 20 flows towards two sides along the second direction until flowing out through the seal seat air inlet holes 321. It can be understood that the number and the opening positions of the air inlet holes 321 of the seal seat are not limited, and can be set as required to meet different requirements.

Further, the sealing seat 30 includes a first sealing section and a second sealing section which are connected to each other in the first direction, the second sealing section is connected to one end of the first sealing section facing the base 10, the inner diameter of the first sealing section is smaller than that of the second sealing section, and a step surface for limiting the heating element 50 is formed between the first sealing section and the second sealing section.

The heating element 50 is accommodated in the first sealing section and abuts against the step surface, the heating element 50 is in interference fit with the side wall 34 of the sealing seat, a heating surface 54 perpendicular to the first direction is formed on the surface of one side of the heating element 50 facing the second sealing section, and a gap is formed between the heating surface 54 and the bottom wall 32 of the sealing seat to define a second middle air passage cavity 40 communicated with the air inlet 321 of the sealing seat. In this way, the two opposite sides of the seal seat bottom wall 32 in the first direction form a first intermediate air passage cavity 20 and a second intermediate air passage cavity 40, respectively, and the air flow flowing out from the first intermediate air passage cavity 20 enters the second intermediate air passage cavity 40 through the seal seat air inlet hole 321.

Furthermore, a heating element air outlet 52 communicated with the second middle air duct cavity 40 penetrates through the center position of the heating element 50 along the first direction, and the central axis of the heating element air outlet 52 coincides with the central axis of the air inlet channel 121. Thus, the air flow flowing out of the seal holder air intake hole 321 enters the second intermediate air duct chamber 40, and then enters the heat generator air outlet hole 52 from the second intermediate air duct chamber 40.

The gas outlet rod 60 is of a hollow tubular structure, one end of the gas outlet rod 60 is inserted into the heating element gas outlet hole 52, the other end of the gas outlet rod 60 extends in the direction away from the heating element 50 along the first direction, the gas outlet rod 60 defines a gas outlet channel 61 communicated with the heating element gas outlet hole 52, and the central axis of the gas outlet channel 61 is coincident with the central axis of the gas inlet channel 121. Thus, the air flow entering the heat-generating body air outlet hole 52 flows out of the atomizing core 100 through the air outlet passage 61.

In the atomizing core 100, the central axis of the air inlet channel 121 and the central axis of the air outlet channel 61 coincide with each other, the central axis of the air inlet hole 321 of the seal seat is arranged in a staggered manner relative to the central axes of the air outlet channel 61 and the air inlet channel 121, the orthographic projection of the air inlet hole 321 of the seal seat on the plane of the heating surface 54 is located in the area of the heating surface 54, and the orthographic projection of the air inlet hole 321 of the seal seat on the plane of the heating surface 54 does not intersect with the air outlet hole 52 of the heating body. Therefore, the airflow flowing in from the air intake passage 121 meanders in the first intermediate air passage chamber 20 and the second intermediate air passage chamber 40, which is different from the prior art that the airflow always flows in the first direction, so that the atomized liquid is prevented from flowing out through the air intake passage 121, and the leakage of the atomized liquid is effectively prevented. Moreover, since the air inlet hole 321 of the sealing seat faces the heating surface 54 of the heating element 50, the air flow flowing out of the air inlet hole 321 of the sealing seat can cool the heating surface 54 rapidly and uniformly, thereby effectively avoiding the over-high temperature of the heating surface 54 and further effectively improving the taste of the aerosol.

In some embodiments, the atomizing cartridge 100 further includes a retaining sleeve 74, a reservoir 72, and a suction nozzle 76. The fixed sleeve 74 is sleeved outside the base 10, the liquid storage tube 72 is a hollow tubular structure with two open ends, the inner wall of one end of the liquid storage tube 72 is in interference fit with the outer wall of the sealing seat 30, the other end of the liquid storage tube 72 extends along the first direction and surrounds the air outlet rod 60, and the air outlet rod 60 defines a liquid storage cavity communicated with the heating body 50 together. The suction nozzle 76 is coupled to an end of the reservoir tube 72 remote from the retaining sleeve 74 and communicates with the air outlet passage 61 of the air outlet stem 60. Specifically, in one embodiment, the reservoir tube 72 and the air outlet stem 60 are integrally formed.

Referring to fig. 4, fig. 4 is a schematic view illustrating an assembly of the electrode 80 and the conductive wire 90 according to an embodiment of the present invention.

In some embodiments, in order to electrically connect the heating element 50 with the power supply assembly, the atomizing core 100 further includes two electrodes 80 and two conductive wires 90. One end of each electrode 80 is inserted into the first electrode mounting hole 123 of the base 10, and the other end of each electrode 80 is inserted into the second electrode mounting hole 323 of the sealing seat 30. One end of each conductive wire 90 is connected to the heating element 50, and the other end of each conductive wire 90 passes through the sealing seat 30 to contact the electrode 80. In this way, the current output by the power supply assembly is transmitted to the heating element 50 through the electrode 80 and the conductive wire 90, and the heating element 50 heats the atomized liquid to generate aerosol.

Further, in order to ensure the reliability of the contact between the conductive wire 90 and the electrode 80, two limiting portions 325 are convexly disposed on one side of the bottom wall 32 of the sealing seat facing the base 10, the two limiting portions 325 are disposed at intervals in the second direction, the two second electrode mounting holes 323 are disposed between the two limiting portions 325, and a limiting groove is disposed on one side of each limiting portion 325 away from the other limiting portion 325 to limit the conductive wire 90. Thus, the conductive wire 90 passing through the bottom wall 32 of the sealing seat is retained in the retaining groove and bent along the retaining groove until contacting the electrode 80.

Specifically, in some embodiments, the limiting groove includes a first limiting section, a second limiting section and a third limiting section which are sequentially connected, the first limiting section extends from the bottom wall 32 of the sealing seat toward the base 10 along the first direction, one end of the second limiting section is connected to the first limiting section, the other end of the second limiting section extends toward the other limiting portion 325 along the second direction, one end of the third limiting section is connected to the second limiting section, and the other end of the third limiting section extends toward the bottom wall 32 of the sealing seat along the first direction and is connected to the hole wall of the second electrode mounting hole 323.

Thus, one end of the conductive wire 90 passing through the bottom wall 32 of the sealing seat extends along the first direction and is limited in the first limiting section, then bends along the second direction toward the other limiting portion 325 and extends and is limited in the second limiting section, and finally extends along the first direction toward the direction away from the base 10 and is limited in the third limiting section to contact with the electrode 80. It can be understood that the shape of the limiting groove and the bending mode of the conductive wire 90 are not limited, and can be set as required to meet different limiting requirements.

Furthermore, for the convenience of operation, the bottom wall 32 of the sealing seat is further provided with an avoiding surface 327 on one side of any one of the limiting portions 325 facing to the other limiting portion 325, and the avoiding surface 327 is recessed inward to leave a sufficient operating space for an operator to bend the conductive wire 90. It is understood that in some embodiments, the conductive line 90 may be bent directly without the limiting portion 325.

The airflow flow path of the atomizing core 100 is as follows:

the air flow first flows from the environment into the inlet channel 121 and then flows in a first direction into the first intermediate air duct chamber 20. The air flow entering the first intermediate air passage cavity 20 flows in the second direction towards both ends of the first intermediate air passage cavity 20 to enter the seal seat air inlet holes 321, and the air flow flowing out of the seal seat air inlet holes 321 enters the second intermediate air passage cavity 40. Since the air inlet hole 321 of the sealing seat is opposite to the heat-generating surface 54, the heat-generating surface 54 can be rapidly and uniformly cooled, then flows towards the middle part of the second middle air channel cavity 40 along the first direction, then enters the air outlet channel 61 of the air outlet rod 60 through the air outlet hole 52 of the heat-generating body, and finally is discharged out of the atomizing core 100 through the suction nozzle 76.

Above-mentioned atomizing core 100 and be equipped with its atomizing device, through setting up of seal receptacle 30 the separation inlet channel 121 and air outlet channel 61, and inlet channel 121 and the seal receptacle inlet port 321 interval setting on the seal receptacle 30 to utilize interval and the dislocation in the space effectively to prevent that atomized liquid or condensate from leaking through inlet channel 121. Moreover, the sealing seat air inlet hole 321 faces the heating surface 54 of the heating element 50, so that the air flow flowing out of the sealing seat air inlet hole 321 can cool the heating surface 54 quickly and uniformly, thereby avoiding the damage to the taste of the aerosol caused by the overhigh temperature of the heating surface 54.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
