Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating device, in particular to a heating and atomizing assembly, an atomizer and an aerosol generating device. BACKGROUND

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

[0003] Among them, the main machine has a battery for supplying power to the atomizer, and the atomizer includes an atomizing core for heating and atomizing, which generally includes a liquid absorbing member and a heating body. The heating body can heat and evaporate the liquid substrate into an aerosol 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, mainly composed of a columnar cotton column and a heating wire arranged on the inner wall of the cotton column. This assembly method is difficult to produce and process, and the heating wire is prone to deformation when placed in the cotton column, resulting in high assembly failure rate. Secondly, because external airflow needs to be introduced to generate aerosol flow to achieve the effect of smoking, the atomizing core has openings on the upper and lower parts for gas flow. The bottom opening method may cause the liquid substrate absorbed in the atomizing core to seep out of the atomizing core and the condensed liquid after atomization to 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 aerosol.

[0005] The existing atomizing core also adopts a blocky structure, which is placed horizontally in the atomizer for heating and atomizing.

[0044] Example 1

[0045] like Figures 1-4 As shown in the figure, the heating atomizing component 3 of this embodiment includes a metal fixing sleeve 5, a liquid suction member 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 suction member 31 is detachably disposed within the cavity 50 and is clamped by the heating element 32 and the fixing sleeve 5. That is, the upper and lower surfaces of the liquid suction member 31 are in contact with the heating element 32 and the fixing sleeve 5, respectively. 1 is used to draw up liquid matrix and transport it upward to the heating element 32 to be heated and atomized into an aerosol for human inhalation. The fixed sleeve 5 has four liquid guiding holes 51 at the end away from the heating element 32 that are connected to the cavity 50. When the heating and atomizing component is used in the atomizer, the liquid matrix in the atomizer is guided to the liquid drawing part 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.

[0046] In the above, the fixing sleeve, the heating body and the liquid absorbing member are assembled and fixed in a detachable manner, the production and assembly process is simple, and the fixing sleeve supports the liquid absorbing member and the heating body to avoid deformation and other problems of the heating body during assembly. The liquid guiding hole is provided at one end of the heating and atomization assembly, which can be directly placed horizontally in the inside of the atomization core, and the liquid matrix is sucked from bottom to top for atomization, thereby avoiding the pollution of the atomizer caused by the downward dripping of the condensed liquid after atomization.

[0047] As preferred, the heating and atomization assembly 3 further comprises a locking assembly for locking the heating body 32 and the fixing sleeve 5. Through the fixation of the locking assembly, the displacement and falling off of the heating body and the liquid absorbing member during use are avoided. The locking assembly comprises a positive column 52 and a positive ring 53. The positive column 52 is vertically arranged between the heating body 32, the liquid absorbing member 31 and the fixing sleeve 5. The positive ring 53 is connected and fixed with the end of the positive column 52 away from the heating body 32, preferably in a threaded connection manner. The end of the positive column 52 close to the heating body 32 is radially provided with a stop ring table 55. Thus, the heating body 32, the liquid absorbing member 31 and the fixing sleeve 5 are locked by the stop ring table 55 and the positive ring 53. The insulating ring 54 is arranged between the positive column 52 and the fixing sleeve 5 to separate them. The positive column 52 is used as a conductive positive electrode of the heating body through the intermediate contact and conduction with the heating body 32. The outer periphery of the heating body is provided with a protrusion 33 arranged on the end face of the fixing sleeve 5, so that a stable and reliable contact connection relationship is formed between the fixing sleeve 5 and the outer periphery of the heating body 32. In the embodiment, the fixing sleeve 5 is made of metal and is used as a conductive negative electrode of the heating body after being connected with the heating body 32. After the heating and atomization assembly is arranged in the atomizer, the positive column and the fixing sleeve are only required to be in contact with the positive probe and the negative probe in the atomizer, without additional wiring. The installation and connection structure is simple and reliable.

[0048] As preferred, the middle part of the heating body 32 is recessed towards the cavity 50 and is provided with a protrusion 35 for pressing the liquid absorbing member 31. This can reduce the deformation of the heating body caused by the locking assembly during locking, and ensure the sufficient and close contact between the heating body 32 and the liquid absorbing member 31.

[0049] In an embodiment, the liquid absorbing member 31 is composed of at least one sheet-shaped cotton sheet. Through the multi-layer structure, cotton sheets with different thickness specifications can be selected to form the liquid absorbing member to meet the assembly requirements.

[0050] In other embodiments, the heating element is made of porous metal; in some alternative implementations, the porous metal is preferably metal felt, foam metal, or heating cloth; wherein, the metal felt is formed by weaving multiple metal fibers, so that the metal felt body has multiple weaving holes, which are used to realize the functions of liquid absorption and liquid conduction, and also to enable the suction airflow to carry out the aerosol in the weaving holes during the suction process, further ensuring the taste of the aerosol; the foam metal has multiple foam pores (i.e., the fine pores and / or micro pores mentioned above), the diameter of which can reach the millimeter level, and the foam pores on the foam metal are almost or all interconnected, which can also realize the function of liquid conduction and enable the aerosol on the foam metal to be carried out as much as possible.

[0051] Example 2

[0052] like Figures 1-10 As shown in this embodiment, an atomizer 100 includes a liquid storage chamber 1, an air guide 2, and a heating atomization assembly 3 as described in Embodiment 1. The liquid storage chamber 1 has a liquid storage cavity 10 for containing a liquid matrix. The air guide 2 is a hollow structure, passing through one end of the liquid storage chamber 1. The inner end of the air guide 2 is an opening communicating with the liquid storage cavity 10, and the outer end of the air guide 2 protrudes outward to form a suction nozzle 20. The liquid storage chamber 1 has an air inlet 11 communicating with the air guide 2 at one end near the suction nozzle 2. The heating atomization assembly 3 is horizontally positioned at the inner end of the air guide 2 to close the opening at the inner end of the air guide 2. The end of the liquid guide hole 51 near the opening communicates with the liquid storage cavity 10 to absorb the liquid matrix in the liquid storage cavity 10 and heat and atomize it. When inhaling at the suction nozzle, air enters from the air inlet and enters the air guide 2. After entering the air guide 2, the aerosol generated by the heating and atomizing component 3 is brought out. In this structure, by placing the heating and atomizing component directly horizontally on the inner end of the air guide, the liquid matrix in the liquid storage chamber is directly discharged from the upper nozzle after being heated and atomized by the heating and atomizing component. The heating and atomizing component draws liquid from bottom to top and conducts it to the heating element, resulting in an even overall liquid supply and avoiding the problems of burnt smell and high-temperature mist caused by insufficient local liquid supply. In addition, the air inlet is located at the end of the liquid storage chamber near the nozzle and is directly connected to the air guide. The liquid storage chamber forms a sealed space. The condensate deposited on the air guide can only be repeatedly absorbed and heated and atomized by the heating and atomizing component after falling off, and will not fall from the bottom of the liquid storage chamber, overflow, or enter the lower power supply component. Moreover, the air inlet is located at the top, so the condensate cannot flow out from the upper air inlet and cause pollution.

[0053] As preferred, the atomizer further comprises an air guide pipe 4 located in the air guide member 2, one end of the air guide pipe 4 is sleeved in the suction nozzle 20, and the other end extends above the heating and atomizing assembly 3 to communicate the heating and atomizing assembly 3 and the suction nozzle 20, and an air inlet channel 21 is formed among the air guide pipe 4, the air guide member 2 and the heating and atomizing assembly 3 to communicate the air inlet hole 11 and the air guide pipe 4, so that the air entering from the air inlet hole needs to flow inward along the air inlet channel to the heating and atomizing assembly 3, and then flow into the air guide pipe 4 from the end of the air guide pipe 4 close to the heating and atomizing assembly, so as to ensure that the aerosol generated after heating and atomization is brought out, and avoid that the air flow flows out from the suction nozzle after not contacting the aerosol because the air inlet hole 11 is too close to the suction nozzle 20.

[0054] As preferred, the end of the air guide pipe 4 above the heating and atomizing assembly 3 is a horn shape with a large outer diameter and a small inner diameter, which can better make the air flow enter and accommodate more aerosol by expanding the aperture; the inner wall of the air guide member 2 is provided with a frustum 22 arranged around the air guide pipe 4 in a spaced manner, and the frustum 22 and the inner wall of the air guide member 2 form a liquid blocking groove 23 with an opening facing the heating and atomizing assembly 3, which can stop the condensate from flowing out to the air inlet hole, that is, when the atomizer is tilted, the condensate on the atomizing core will be stored in the liquid blocking groove, thereby avoiding the problem of condensate flowing out.

[0055] As preferred, the atomizer further comprises a positive electrode elastic needle 12 and a negative electrode elastic needle 13 penetrating the liquid storage bin 1 away from the suction nozzle 2, the positive electrode elastic needle 12 abuts against the positive electrode ring 53, and the negative electrode elastic needle 13 abuts against the fixed sleeve 5, so as to realize the electrical connection between the heating body 32 and the outside, and the positions of the fixed sleeve 5 and the positive electrode ring 53 cannot be moved, so that the electrical connection structure is firm and reliable.

[0056] As preferred, the atomizer further comprises an air adjusting ring 6, which is rotationally arranged in the liquid storage bin 1 close to the suction nozzle 2, and the air adjusting ring 6 is provided with a through hole 61, when the air adjusting ring 6 rotates relative to the liquid storage bin 1, the through hole 61 and the air inlet hole 11 at least partially correspond to the conduction or misalignment sealing, that is, after rotation, the opening and closing of the air inlet hole will have three states, including the fully open state formed by the overall conduction of the air inlet hole 11 and the through hole 61, the half open and half closed state formed by the partial conduction of the air inlet hole 11 and the through hole 61, and the fully closed state formed by the complete misalignment of the air inlet hole 11 and the through hole 61.

[0057] As preferred, the atomizer further comprises an elastic locking member arranged between the air adjusting ring 6 and the liquid storage bin 1, the elastic locking member comprising a sliding member 7 slidingly arranged on the liquid storage bin 1 and an elastic member 8 arranged between the sliding member 7 and the liquid storage bin 1, and an arc-shaped groove 62 is concavely arranged on the inner wall of the air adjusting ring 6 and engaged with the outer end of the sliding member 7; when the arc-shaped groove 62 corresponds to the sliding member 7, the sliding member 7 is clamped into the arc-shaped groove 62 under the action of the elastic member 8, forming a limiting effect, and when a certain pressure is applied to the air adjusting ring 6 to make it rotate, the sliding member 7 can slide out of the arc-shaped groove 62 and compress the elastic member by using the characteristics of the arc-shaped groove 62, so as to realize the rotation of the air adjusting ring 6; it can be understood that the elastic member 8 is preferably a spring.
