Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating device, in particular to an atomizer capable of guiding airflow and an aerosol generating device. BACKGROUND

[0002] The aerosol generating device can heat the aerosol substrate and atomize to generate aerosol. At present, the split type aerosol generating device is mainly composed of an atomizer and a host for power supply, and the integrated type aerosol generating device assembles the atomizing part and the power supply part on the same shell.

[0003] Among them, the host has a battery for supplying power to the atomizer, and the atomizer includes a heating atomizing core, which generally includes a liquid absorbing member and a heating body. The heating body can heat and evaporate the liquid substrate into gas mist when powered on, for the user to inhale into the mouth.

[0004] The deficiencies of the existing atomizing core are as follows: the atomizing core generally adopts a vertical columnar structure. Since external airflow needs to be introduced to generate airflow and achieve the effect of smoking, the upper and lower parts of the atomizing core are open for airflow. The liquid in the atomizing core may seep out of the atomizing core and the condensed liquid after atomization may also exist backflow, and then the liquid may drip down from the lower opening of the atomizing core, causing pollution of the atomizer. In addition, the columnar structure may cause uneven liquid supply in the liquid absorbing member, that is, the amount of liquid in the liquid absorbing member above the liquid guide hole is less than that at the lower end. Under the high temperature of the heating body, local liquid supply may be insufficient, causing a burnt taste and easy inhalation of high temperature gas mist.

[0005] Some existing atomizing cores adopt a horizontal atomizing core to solve the above-mentioned vertical atomizing core problem, but most of the existing horizontal atomizing cores have unreasonable air inlet channel design, which causes the airflow to not fully contact the atomizing core. First, it may affect the amount of aerosol carried by the airflow, and second, the atomized aerosol may not be fully carried out, and the remaining part may easily condense into condensed liquid.

[0016] A liquid suction member is arranged in the containing cavity to be clamped by the heating body and the fixing sleeve.

[0017] Further, the atomizing core further comprises a locking assembly for locking the heating body and the fixing sleeve, the locking assembly comprises a positive pole column penetrating the heating body, the liquid suction member and the fixing sleeve, and a positive pole ring connected to the end of the positive pole column away from the heating body, and an insulating ring is arranged between the positive pole column and the fixing sleeve to separate them.

[0018] Further, a convex edge of the heating body is arranged on the end face of the fixing sleeve, and a convex part of the heating body is recessed towards the containing cavity to press the liquid suction member.

[0019] Further, the liquid absorbing member is composed of at least one sheet-shaped cotton sheet.

[0020] Further, the atomizer capable of guiding airflow further comprises a positive needle and a negative needle penetrating into the liquid storage bin away from the suction nozzle end, the positive needle abuts against the positive ring, and the negative needle abuts against the fixed sleeve.

[0021] Further, the atomizer further comprises an air adjusting ring, which is rotationally arranged at the end of the liquid storage bin close to the suction nozzle, and the air adjusting ring is provided with a through hole, when the air adjusting ring rotates relative to the liquid storage bin, the through hole and the air inlet hole at least partially correspond to the open or misaligned closed state.

[0022] Further, the atomizer further comprises an elastic locking member arranged between the air adjusting ring and the liquid storage bin, the elastic locking member comprises a sliding member sliding on the liquid storage bin and an elastic member arranged between the sliding member and the liquid storage bin, and the inner wall of the air adjusting ring is concavely provided with an arc-shaped groove matched with the outer side end of the sliding member.

[0023] In the second aspect, the present application also provides an aerosol generating device, which comprises a host for power supply and the atomizer capable of guiding airflow according to any one of the first aspect.

[0024] The present application has the following beneficial effects:

[0025] The atomizer in the present application changes the direction of airflow through the first guiding part and the second guiding part arranged in sequence in the air inlet channel, first, the first guiding part converges the airflow to the center, through the converging mode, one is to concentrate the airflow, which is convenient for guiding control, and the other is to improve the pressure and speed of the airflow, and then the second guiding part guides the airflow to the inner wall of the suction nozzle, and then the rebounding effect of the inner wall of the suction nozzle makes the airflow contact the atomizing core in a diagonal direction, which ensures that the airflow can contact the entire surface of the atomizing core, so as to control the transmission process of the airflow to achieve the purpose of guiding the entire surface of the aerosol, which improves the guided amount of the aerosol after atomization and avoids the condensation problem caused by the aerosol residue on the surface of the atomizing core.

[0026] Secondly, the atomizing core is directly placed in the inside of the air guiding member, so that the liquid matrix in the liquid storage bin is directly discharged from the suction nozzle after being heated and atomized by the atomizing core, the air inlet hole is arranged at the end of the liquid storage bin close to the suction nozzle and directly communicates with the suction nozzle, the liquid storage cavity forms a closed space, the condensed liquid deposited on the air guiding member can only be repeatedly absorbed and heated and atomized, and cannot fall from the bottom of the liquid storage bin or enter the lower power supply assembly, and the air inlet hole is located above, so the condensed liquid cannot flow out from the air inlet hole above to cause pollution.

[0027] Furthermore, the fixing sleeve, heating element, and liquid intake component in this atomizing core are assembled and fixed in a detachable manner, simplifying the manufacturing and assembly process. The fixing sleeve supports the liquid intake component and heating element, preventing defects such as deformation of the heating element during assembly. Moreover, the atomizing core draws liquid from the bottom up and conducts it to the heating element, ensuring even liquid supply and avoiding issues such as burnt taste or high-temperature aerosol caused by insufficient liquid supply in certain areas. The inverted truncated cone and the resulting liquid-blocking groove inside the mouthpiece prevent condensate from flowing out to the air inlet. That is, when the atomizer is tilted, the condensate on the atomizing core will be contained in the liquid-blocking groove, thus preventing the condensate from overflowing.

[0046] Example 1

[0047] As Figures 1-11As shown, the atomizer 100 capable of guiding airflow shown in the embodiment includes a liquid storage bin 1, a gas guiding member 2 and an atomizing core 3. The liquid storage bin 1 is internally provided with a liquid storage cavity 10 for accommodating liquid matrix. The gas guiding member 2 is a hollow structure, and the gas guiding member 2 is arranged at one end of the liquid storage bin 1. The inner end of the gas guiding member 2 is an opening in communication with the liquid storage cavity 10. The outer end of the gas guiding member 2 outwardly protrudes to form a suction nozzle 20. The liquid storage bin 1 is provided with an air inlet hole 11 in communication with the gas guiding member 2 at the end close to the gas guiding member 2. The atomizing core 3 is horizontally arranged at the opening of the inner end of the gas guiding member 2 and is in communication with the liquid storage cavity 10, so as to absorb the liquid matrix in the liquid storage cavity 10 and heat and atomize. When air is inhaled at the suction nozzle 20, the air is inhaled from the air inlet hole 11 and enters the gas guiding member. After the airflow enters the gas guiding member 2, the aerosol generated by the heating and atomization of the atomizing core 3 is carried out. The atomizing core is a flat planar structure. In the structure, the atomizing core is directly horizontally arranged at the opening of the inner end of the gas guiding member, so that the liquid matrix in the liquid storage bin 1 is directly discharged from the suction nozzle 20 after being heated and atomized by the atomizing core 3. The air inlet hole 11 is arranged at the end of the liquid storage bin 1 close to the suction nozzle 20 and is directly in communication with the gas guiding member 2. The condensed liquid and the like deposited on the atomizing core 3 can only be repeatedly absorbed and heated and atomized, and cannot fall from the bottom of the liquid storage bin and overflow or enter the lower power supply assembly. The air inlet hole 11 is located above, and the condensed liquid cannot flow out from the air inlet hole 11 above to cause pollution.

[0048] As preferred, the atomizer further comprises an air guide pipe 4 arranged in the air guide member 2, one end of the air guide pipe 4 is sleeved in the suction nozzle 20, the other end extends above the atomizing core 3 to communicate the atomizing core 3 and the suction nozzle 20, and there is a certain height difference between the atomizing core 3 and the air guide pipe 4 to form a fault to prevent the air guide pipe from tilting and avoid large particle substances flowing out from the air guide pipe; the air guide pipe 4, the air guide member 2 and the atomizing core 3 enclose an air inlet channel 21 which communicates the air inlet hole 11 and the air guide pipe 4, so that the air entering from the air inlet hole 11 needs to flow inward along the air inlet channel to the atomizing core 3 first, and then flows into the air guide pipe 4 from the end of the air guide pipe 4 close to the atomizing core 3 to ensure that the aerosol generated after heating and atomization is carried out, and to avoid the air flow from the suction nozzle after the air flow is not in contact with the aerosol because the air inlet hole 11 is too close to the suction nozzle 20; in order to control the flow direction of the air flow, the first guide part 22 which guides the air flow to the outer wall of the air guide pipe 4 and the second guide part 41 which guides the air flow to the inner wall of the air guide member 2 are arranged in the air inlet channel 21 in sequence according to the direction of the air flow, so that the air flow rebounds and contacts the entire surface of the atomizing core; it can be understood that the air guide pipe 4 is located in the middle of the air guide member 2, so that the first guide part 22 converges the air flow to the center, and through the converging mode, the air flow is concentrated, which is convenient for guiding and controlling, and the pressure and speed of the air flow are improved; the second guide part 41 is located below the gap between the air guide pipe 4 and the first guide part 22, so as to guide the converged air flow to the inner wall of the air guide member 2 by the second guide part 41, and then use the rebounding effect of the inner wall of the air guide member 2 to make the air flow contact the atomizing core 3 in an oblique direction to ensure that the air flow can contact the entire surface of the atomizing core 3 (as shown in Figure 6 ), so as to achieve the purpose of guiding out the entire surface aerosol by controlling the transmission process of the air flow, improve the guiding amount of the aerosol after atomization, and avoid the condensation problem caused by the residual aerosol on the surface of the atomizing core.

[0049] As preferred, the first guide part 22 is an inverted circular truncated cone arranged around the air guide pipe 4 to form a first inclined surface on the inner wall of the inverted circular truncated cone which guides the air flow to the outer wall of the air guide pipe 4; the end of the air guide pipe 4 above the atomizing core 3 is provided with a second guide part 41 in the shape of a horn, which expands the aperture, one is to better enable the air flow to enter and accommodate more aerosol, and the other is to form a second inclined surface on the outer side of the end of the air guide pipe 4 close to the atomizing core 3 which guides the air flow to the inner wall of the air guide member 2.

[0050] As preferred, the first guide part 22 and the inner wall of the air guide member 2 form a liquid blocking groove 23 with an opening facing the atomizing core 3, which can stop the condensed liquid from flowing out to the air inlet hole, that is, when the atomizer is tilted, the condensed liquid on the atomizing core will be stored in the liquid blocking groove, thereby avoiding the problem of outflow and overflow of the condensed liquid.

[0051] As preferred, as shown in Figures 8 to 11As shown, the atomizing core 3 includes a metal fixing sleeve 5, a liquid-absorbing component 31, and a heating element 32. A groove is provided at one end of the fixing sleeve 5. The heating element is detachably mounted on the grooved end of the fixing sleeve 5, forming a cavity 50 between the fixing sleeve 5 and the heating element 32. The liquid-absorbing component 31 is detachably disposed within the cavity 50 and is clamped by the heating element 32 and the fixing sleeve 5. Specifically, the upper and lower surfaces of the liquid-absorbing component 31 are in contact with the heating element 32 and the fixing sleeve 5, respectively. The liquid-absorbing component 31 is used to absorb the liquid matrix and transport it upwards to the heating element 32, where it is heated and atomized into an aerosol for inhalation. The fixing sleeve 5 is located away from the heating element. One end of the body 32 is provided with four liquid guiding holes 51 that communicate with the cavity 50. When the heating atomizing component is used in the atomizer, the liquid matrix in the atomizer is introduced to the liquid suction component 31 through the liquid guiding holes 51. Several air guiding holes 34 are provided through the heating element 32. The heated and atomized aerosol flows out from the air guiding holes 34 and comes into contact with the air, and then the air carries the aerosol outward. In this structure, the fixing sleeve, heating element and liquid suction component are assembled and fixed in a detachable manner. The production and assembly process is simple. The fixing sleeve supports the liquid suction component and heating element, avoiding problems such as deformation of the heating element during assembly.

The locking assembly prevents the heating element and the liquid-absorbing component from shifting or falling off during use. The locking assembly includes a positive electrode post 52 and a positive electrode ring 53. The positive electrode post 52 passes vertically between the heating element 32, the liquid-absorbing component 31, and the fixing sleeve 5. The positive electrode ring 53 is connected and fixed to the end of the positive electrode post 52 furthest from the heating element 32, preferably using a threaded connection. A stop ring 55 is radially protruding from the end of the positive electrode post 52 closest to the heating element 32. This, along with the positive electrode ring 53, locks the heating element 32, the liquid-absorbing component 31, and the fixing sleeve 5. An insulating ring 54 is provided between the 2 and the fixed sleeve 5 to separate them. The positive electrode post 52 and the heating element 32 are connected by intermediate contact, so that the positive electrode post is used as the conductive positive electrode of the heating element. The outer periphery of the heating element is provided with a protrusion 33 that overlaps one end face of the fixed sleeve 5, so that a stable and reliable contact connection is formed between the fixed sleeve 5 and the outer periphery of the heating element 32. In this embodiment, the fixed sleeve 5 is made of metal and is used as the conductive negative electrode of the heating element after being connected to the heating element 32. After the heating atomizing component is placed in the atomizer, it is only necessary to make the positive electrode post and the fixed sleeve contact and connect with the positive electrode probe and the negative electrode probe in the atomizer respectively. No additional wiring is required. The installation and connection structure is simple and reliable.

[0053] As preferred, the middle part of the heating body 32 is concave towards the cavity 50 and is provided with a convex part 35 for pressing the liquid suction member 31, which is to reduce the deformation of the heating body caused by the locking assembly when it is locked, and to ensure the full and close contact between the heating body 32 and the surface of the liquid suction member 31.
