The present application is described in detail below with reference to the accompanying drawings and examples.

Please refer to fig. 1 to 11. In this embodiment, an atomizer and an electronic atomization device are provided, and the electronic atomization device can be applied to the technical fields of medical treatment, beauty treatment, electronic cigarette and the like, and is used for heating an aerosol generating substrate when being electrified so as to form aerosol. The aerosol-generating substrate may be a liquid formulation, a tobacco tar, or any other liquid suitable for electronic atomization, wherein the drug is dispersed in a liquid solvent. Specifically, the atomizer may include a liquid storage jacket 11, a bracket 33, a base 6, and an atomizing core 5.

As shown in fig. 1 to 6, a liquid storage chamber 11 is provided within the liquid storage sleeve 1, an atomizing chamber 7 is formed between the atomizing core 5 and the base 6, wherein the liquid storage chamber 11 is used for storing an aerosol-generating substrate and is capable of releasing the aerosol-generating substrate to the atomizing core 5, and when the aerosol-generating substrate is heated by the atomizing core 5, the aerosol-generating substrate is atomized in the atomizing chamber 7 to form an aerosol.

Specifically, be provided with stock solution chamber 11 in stock solution cover 1, stock solution cover 1 is connected with base 6, be provided with support 3 and atomizing core 5 in stock solution cover 1, wherein, atomizing core 5 installs on support 3, support 3 installs on base 6, form atomizing chamber 7 between atomizing core 5 and the base 6, be provided with air vent 31 and first condensate holding tank 32 on support 3, air vent 31 and stock solution chamber 11 and first condensate holding tank 32 intercommunication, form condensate and lead out groove 33 between support 3 outer wall and base 6 inner wall, and condensate lead out groove 33 is linked together with first condensate holding tank 32 and atomizing chamber 7. The liquid storage cavity 11 stores aerosol generating matrix, and when the aerosol generating matrix flows into the atomizing core 5 from the liquid storage cavity 11, aerosol can be produced through atomization under the action of the atomizing core 5. Since part of the atomized aerosol remains in the atomizing chamber 7 during use of the atomizer, and then the part of the atomized aerosol is diffused to places with gaps or spaces such as the air vent hole 31 and the first condensate storage groove 32, and is condensed to form aerosol condensate in the places, meanwhile, since the pressure in the liquid storage chamber is reduced after the aerosol generating substrate flows into the atomized core 5 and is atomized, in order to keep the air pressure balance in the liquid storage chamber, the outside air pushes the air vent hole 31 and/or the aerosol condensate in the first condensate storage groove 32 to reach the liquid storage chamber 11 under the action of the atmospheric pressure, and then the air can enter the liquid storage chamber 11, so that the air pressure inside and outside the liquid storage chamber 11 is balanced. However, the aerosol condensate and the aerosol-generating substrate in the liquid storage chamber 11 are easy to deteriorate after being mixed, so in the utility model, the condensate guiding groove 33 is formed between the outer wall of the bracket 3 and the inner wall of the base 6, the condensate guiding groove 33 is communicated with the first condensate storage groove 32 and the atomization chamber 7, and the aerosol condensate in the air vent hole 31 and the first condensate storage groove 32 is guided into the atomization chamber 7 through the condensate guiding groove 33, thereby avoiding the aerosol condensate in the air vent hole 31 and the first condensate storage groove 32 from flowing into the liquid storage chamber 11, and avoiding the aerosol-generating substrate in the liquid storage chamber 11 from being deteriorated and taste due to the influence of the aerosol condensate.

Referring to fig. 1, a vent pipe 12 is disposed in the liquid storage sleeve 1, the vent pipe 12 is communicated with the atomization cavity 7, and when the aerosol is atomized by the atomizing core 5 in the atomization cavity 7, the generated aerosol is outwards dispersed from the vent pipe 12 for a user to inhale. The end face of the support 3 facing the liquid storage cavity 11 is provided with a sealing cover 2, the sealing cover 2 is used for preventing aerosol generating matrixes in the liquid storage cavity 11 from flowing into the ventilation hole 31, and when ventilation is carried out, air pushes up the sealing cover 2 under the action of atmospheric pressure, so that a gap exists between the sealing cover 2 and the ventilation hole 31, and gas can enter the liquid storage cavity 11 through the gap. The first condensate storage groove 32 is arranged on the outer surface of the support 3, a containing groove body is formed between the inner wall of the sealing cover 2 and the first condensate storage groove 32 and is used for containing aerosol remained in the atomization cavity 7, the aerosol is reduced or prevented from entering the air vent hole 31, meanwhile, the aerosol condensate formed after the aerosol is condensed is stored in the containing groove body, and the aerosol condensate in the air vent hole 31 also flows into the containing groove body to be stored, so that the air is prevented from being influenced by the fact that the aerosol condensate blocks the air vent hole 31 and timely enters the liquid storage cavity 11. In the utility model, the shape of the formed accommodating groove is preferably set as an elliptical ring groove, and the shape and the volume of the accommodating groove are not particularly limited in the application because the actual design style and style are different, and can be set according to the actual situation. A condensate outlet groove 33 is provided below the first condensate storage groove 32, and the other end of the condensate outlet groove 33 is communicated with the atomizing chamber 7, so that aerosol condensate in the first condensate storage groove 32 enters the condensate outlet groove 33 and is guided into the atomizing chamber 7 to be stored through the condensate outlet groove 33.

With continued reference to fig. 1, the condensate guiding groove 33 is located between the first condensate storing groove 32 and the atomizing chamber 7, the condensate guiding groove 33 is configured to guide the aerosol condensate in the first condensate storing groove 32 into the atomizing chamber 7, wherein the condensate guiding groove 33 is configured as a first guiding groove 331 and a second guiding groove 332, one end of the first guiding groove 331 is communicated with the lower end of the first condensate storing groove 32, the other end of the first guiding groove 331 is communicated with one end of the second guiding groove 332, and the other end of the second guiding groove 332 is communicated with the atomizing chamber 7. The first lead-out groove 331 is located between the end surface of the base 6 facing the liquid storage chamber 11 and the first condensate storage groove 32, and the second lead-out groove 332 is located between the inner side wall of the base 6 and the outer peripheral surface of the holder 3. The first guiding-out groove 331 and the second guiding-out groove 332 are formed between the base 6 and the support 3, so that the manufacturing and the assembly are facilitated, and the problem that the first guiding-out groove 331 is located at the support 3 and the second guiding-out groove 332 is located at the base 6 so as to be difficult to align is avoided.

The tank volume of the first guiding-out tank 331 is larger than that of the second guiding-out tank 332, so that the condensate guiding-out tank 33 formed by combining the first guiding-out tank 331 and the second guiding-out tank 332 has a funnel-like shape, that is, one end of the first guiding-out tank 331 connected with the first condensate storing tank 32 is a large end, one end of the second guiding-out tank 332 communicated with the atomizing chamber 7 is a small end, and when the aerosol condensate in the first condensate storing tank 32 flows to the condensate guiding-out tank 33, the large end can absorb or quickly guide the aerosol condensate in the first condensate storing tank 32 to flow to the second guiding-out tank 332, so as to prevent more aerosol condensate from being stored in the first condensate storing tank 32. When more aerosol remains in the atomizing chamber 7, the small end of the second guiding-out groove 332 is communicated with the atomizing chamber 7, so that the aerosol is reduced from entering the first condensate storage groove 32 and the air vent hole 31 through the condensate guiding-out groove 33, the aerosol condensate in the first condensate storage groove 32 and the air vent hole 31 is further reduced, and the aerosol condensate is further reduced from being pushed into the oil storage chamber 11. In the present embodiment, the tank volumes of the first lead-out tank 331 and the second lead-out tank 332 are not particularly limited in this application, and may be set according to actual conditions.

In the overall direction, the condensate guiding groove 33 extends longitudinally along the atomizer, so that aerosol condensate in the first condensate storage groove 32 flows out of the condensate guiding groove 33 more easily under the action of gravity, the amount of the aerosol condensate stored in the first condensate storage groove 32 is reduced, and the aerosol condensate is further reduced to be pushed to the liquid storage cavity 11. That is, the aerosol condensate in the first condensate storage tank 32 enters the first guiding-out groove 331 and flows to the second guiding-out groove 332 along the first guiding-out groove 331, and flows into the atomizing chamber 7 rapidly under the action of gravity, so as to avoid excessive aerosol condensate accumulation in the first condensate storage tank 32.

Referring to fig. 3, a ventilation groove 35 is further disposed on the outer peripheral surface of the support 3, a first end of the ventilation groove 35 is communicated with the first condensate storage groove 32, and a second end of the ventilation groove 35 is communicated with the atomization cavity 7, and because the first condensate storage groove 32 is communicated with the ventilation hole 31, air can enter the liquid storage cavity 11 through the atomization cavity 7, the ventilation groove 35, the first condensate storage groove 32 and the ventilation hole 31 in sequence to maintain air pressure balance. When the atomizer works and the first and second lead-out grooves 331 and 332 are used for guiding the aerosol condensate to be conveyed to the atomization cavity 7, air enters the liquid storage cavity 11 through the atomization cavity 7, the ventilation groove 35, the first condensate storage groove 32 and the ventilation hole 31 to maintain air pressure balance, the normal work of the atomizer is maintained, and the aerosol condensate in the first and second lead-out grooves 331 and 332 is prevented from being reversely pushed to the first condensate storage groove 32 and the ventilation hole 31 and even reaching the liquid storage cavity 11. When both the ventilation groove 35 and the condensate outlet groove 33 are used for conveying aerosol condensate to the atomization cavity 7, the ventilation groove 35 or the condensate outlet groove 33 with smaller aerosol condensate amount is automatically selected for pushing by air, so that air enters the liquid storage cavity 11 to maintain air pressure balance, and therefore the aerosol condensate can be reduced or prevented from entering the liquid storage cavity 11, and aerosol generating substrates in the liquid storage cavity 11 are protected. Meanwhile, the balance of the air pressure inside and outside the liquid storage cavity 11 can be maintained, the atomizer works normally, and the aerosol generating substrate has no peculiar smell.

In practical applications, when the first condensate storage tank 32 is full of aerosol condensate, in order to avoid or reduce the aerosol condensate in the first condensate storage tank 32 from entering the liquid storage chamber 11 through the ventilation hole 31 and increase the dredging speed of the first condensate storage tank 32, the aerosol condensate in the first condensate storage tank 32 may be led out into the atomization chamber 7 through the ventilation slot 35 and the condensate guiding-out slot 33, where the ventilation slot 35 guides the aerosol condensate in the first condensate storage tank 32 into the atomization chamber 7, so that the atomization core 5 performs secondary atomization on the aerosol condensate, and since the condensate guiding-out slot 33 is communicated with the ventilation slot 35, in order to avoid the aerosol condensate in the condensate guiding-out slot 33 from flowing back into the ventilation slot 35 and causing the aerosol condensate to accumulate in the ventilation slot 35, in this application, a liquid blocking wall 34 is disposed at a second port of the ventilation slot 35, that is, a port communicating with the atomization chamber 7, and the condensate guiding-out slot 33 and the ventilation slot 35 may not be separated, so that the aerosol condensate in the condensate guiding-out slot 33 enters into the ventilation slot 35.

When the atomizer is used, the air vent hole 31 is matched with the air exchange groove 35 to supplement external air into the liquid storage cavity 11, and the air in the atomizing cavity 7 pushes aerosol condensate in the air exchange groove 35 to move towards the liquid storage cavity 11 under the action of atmospheric pressure, and the first condensate storage groove 32 is arranged between the air vent hole 31 and the air exchange groove 35, so that the aerosol condensate can enter the first condensate storage groove 32 to be stored, or flows into the atomizing cavity 7 from the condensate guide groove 33, and the aerosol condensate is prevented from entering the air vent hole 31.

A second condensate storage groove 36 is provided at the outer circumferential surface of the holder 3, the second condensate storage groove 36 being in communication with the atomizing chamber 7 and the first condensate storage groove 32 such that the remaining aerosol in the atomizing chamber 7 diffuses or flows into the second condensate storage groove 36, for example, when the first condensate storage groove 32 is filled with aerosol, flows into the second condensate storage groove 36 from the condensate outlet groove 33, and is stored in the second condensate storage groove 36 until condensed, reducing the amount of aerosol in the first condensate storage groove 32; it should be noted that the second condensate storage tank 36 may store condensate in addition to the manner described above. Since the holder 3 is provided in the liquid storage jacket 1, there is also a space between the outer circumferential surface of the holder 3 and the inner wall of the liquid storage jacket 1, and when the aerosol-generating substrate is atomized by the atomizing core 5, the generated aerosol flows into the second condensate storage tank 36 through the space, and the aerosol condensate remains in the second condensate storage tank 36 after the aerosol is cooled. Since the second condensate storage tank 36 is communicated with the atomizing chamber 7, aerosol condensate can be introduced into the atomizing chamber 7, and the second condensate storage tank 36 can be provided to better collect and store aerosol condensate.

Referring to fig. 3 to 4, in order to further collect and store the aerosol condensate, the situation that too much aerosol condensate flows into the atomization cavity 7 and leaks from the atomization cavity 7 to the outside of the atomizer is avoided. In this application, the third condensate storage groove 61 is provided on the outer circumferential surface of the base 6, and since the base 6 is installed in the liquid storage sleeve 1, there will be a certain interval between the liquid storage sleeve 1 and the outer circumferential surface of the base 6, when the atomizing core 5 atomizes the aerosol-generating substrate, the generated aerosol will flow into the third condensate storage groove 61 through the interval, and after the aerosol is cooled, the aerosol condensate will be stored in the third condensate storage groove 61. Since the third condensate storage tank 61 is isolated from the atomization cavity 7, the aerosol condensate in the third condensate storage tank 61 cannot directly flow into the atomization cavity 7, and leakage of the aerosol condensate caused by excessive accumulation of the aerosol condensate in the atomization cavity 7 is avoided.

Referring to fig. 6, the atomizing core 5 is mounted at the support 3, specifically, a mounting groove 38 is provided on the support 3, and in order to ensure stability and sealing effect of the atomizing core 5 placed on the mounting groove 38, a sealing seat 4 is sleeved outside the atomizing core 5, and the atomizing core 5 is placed on the mounting groove 38 after being sleeved with the sealing seat 4. Wherein, a condensate adsorption groove 37 is arranged on the inner wall of the mounting groove 38, and the condensate adsorption groove 37 is communicated with the atomizing cavity 7. It should be noted that, when the atomizing core 5 atomizes the aerosol-generating substrate, the aerosol may flow through the condensate adsorption groove 37, and the aerosol condensate formed after the aerosol is cooled may remain in the condensate adsorption groove 37, so the condensate adsorption groove 37 forms a liquid bridge connection with the atomizing core 5 through the aerosol condensate, so that the aerosol condensate may be absorbed by the atomizing core 5 for secondary atomization. A plurality of condensate adsorption grooves 37 are formed in the inner wall of the mounting groove 38 of the bracket 3, the specific number of the condensate adsorption grooves 37 is not particularly limited in the application, the condensate adsorption grooves 37 can be set according to practical situations, and the aerosol condensate can be stored.

Specifically, the condensate adsorption grooves 37 are distributed in the notch area of the condensate guiding groove 33, that is, the condensate guiding groove 33 is taken as a midpoint, and extend towards two sides to form a plurality of condensate adsorption grooves 37, the notch area of the condensate adsorption grooves 37 is smaller than that of the condensate guiding groove 33, so that capillary guiding and adsorption phenomena are realized, aerosol condensate is locked in the condensate adsorption grooves 37, and stable liquid suction guiding can be provided for liquid bridge connection between the condensate adsorption grooves 37 and the atomizing core 5, so that a liquid bridge is not easy to break. The provided condensate adsorption groove 37 can disperse the liquid collecting pressure of the condensate guiding groove 33, so that not only can the aerosol condensate be prevented from being stored in the condensate guiding groove 33 to influence the transportation of the aerosol condensate, but also the aerosol condensate can be smoothly guided out of the first condensate storage groove 32 into the atomizing core 5 for secondary atomization, and the aerosol condensate in the first condensate storage groove 32 is consumed, so that the influence of the aerosol condensate in the liquid storage cavity 11 on the quality guarantee period and taste of the aerosol generating substrate is avoided.

Referring to fig. 1, a liquid guiding gap 71 is formed between the atomizing core 5 and the condensate guiding groove 33, the condensate guiding groove 33 conducts aerosol condensate into the atomizing core 5 through the liquid guiding gap 71, wherein the liquid guiding gap 71 is disposed below the second guiding groove 332, and when the aerosol condensate is conducted to the second guiding groove 332, the aerosol condensate flows from the second guiding groove 332 to the condensate adsorbing groove 37, and finally enters the liquid guiding gap 71 to form a liquid bridge to be connected to the atomizing core 5. At this time, the atomizing core 5 can absorb and secondarily atomize the aerosol condensate, so that not only can the aerosol condensate be stored in the condensate guiding groove 33 be reduced, but also the leakage probability of too much aerosol condensate in the atomizing cavity 7 can be reduced. Since the gap size of the liquid guiding gap 71 is small, the gap size is, for example, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.65mm; because the aerosol condensate has a certain viscosity, the aerosol condensate is not easy to drop in the gap against gravity, so that the aerosol condensate in the second guide-out groove 332 enters the atomization core 5 through capillary drainage generated by the liquid guide gap 71, and the atomization core 5 has an adsorption function after secondary atomization of the aerosol condensate, so that the liquid guide gap 71 can continuously convey the aerosol condensate to the atomization core 5, and the atomization core 5 is convenient for secondary atomization of the aerosol condensate.

When the tapered ventilation holes 311 have aerosol condensate, the aerosol condensate can flow into the first condensate storage groove 32 and the fourth condensate storage groove 3211 through the larger openings, thereby accelerating the flow rate and the circulation speed of the aerosol condensate. As the aerosol condensate enters the fourth condensate holding tank 3211, it flows along the ramp 3212 into the fifth condensate holding tank 3213.

Note that, the liquid guiding medium 72 may be provided with a sponge or other article in addition to cotton, and the liquid guiding medium 72 is not particularly limited in this application and may be set according to actual conditions.

The liquid guiding medium 72 is circumferentially arranged on the outer circumferential surface of the atomizing core 5, and when aerosol condensate enters the atomizing cavity 7, the aerosol condensate needs to pass through the liquid guiding medium 72, and because the aerosol condensate flows from top to bottom and is conducted under the action of gravity, the liquid guiding medium 72 can absorb more aerosol condensate; when the aerosol condensate passes through the liquid guide medium 72, the aerosol condensate can more smoothly enter the atomizing core 5 and the atomizing cavity 7, even if the liquid guide medium 72 is in a saturated state, the aerosol condensate falling into the liquid guide medium 72 smoothly flows into the atomizing core 5 for secondary atomization, so that the carrying capacity of the aerosol condensate in the liquid guide medium 72 is reduced; at the same time, a small amount of aerosol condensate is also stored in the nebulization chamber 7.
