Background

Atomizer among the electron atomizing device includes stock solution cup and atomizing core usually, and the stock solution cup is used for storing and treats the atomizing material, and the atomizing core is including interconnect's leading liquid and heat-generating body, and the atomizing process of atomizing core generally is: the material to be atomized in the liquid storage cup firstly permeates into the liquid guide body with capillary pores, and then is transferred to the heating body of the atomizing core for heating and evaporation, so that aerosol for a user to suck is formed.

At present, under a normal temperature state, a substance to be atomized stored in a liquid storage cup of an atomizer is generally in a liquid state. However, to avoid leakage during storage and transportation of the atomizer, the substance to be atomized may also be in a solid or semi-solid state.

However, when the solid or semi-solid substance to be atomized is used, the solid or semi-solid substance to be atomized needs to be converted into a liquid substance to be atomized with higher fluidity by means of preheating treatment, so as to prevent dry burning of the heating element of the atomizing core due to liquid shortage and even damage to the atomizing core. The preheating treatment is generally to add a heating device on the periphery of the liquid storage cup, and when the atomizer enters a preheating mode, the heating device arranged on the periphery of the liquid storage cup starts to work, so that the solid or semisolid substance to be atomized is heated and converted into the liquid substance to be atomized. However, since the heat generated by the heating device is conducted from the periphery of the liquid storage cup to the housing of the liquid storage cup and then indirectly conducted to the solid or semi-solid substance to be atomized in the liquid storage cup, the heat conduction process is slow, and the preheating time is increased. Moreover, the heat generated by the heating device is indirectly transferred to the solid or semi-solid substance to be atomized in the liquid storage cup, which results in partial heat loss during the transfer process, thereby increasing the energy consumption of the heating device.

Referring to fig. 1 to 7, the present invention provides an atomizer, which includes an outer housing 100, an inner housing 200, and an atomizing core 300. The inner shell 200 is arranged in the outer shell 100, at least one air outlet channel 210 is formed between the inner wall of the outer shell 100 and the outer wall of the inner shell 200, a liquid storage cup 220 for storing a substance to be atomized is formed by enclosing the inner wall of the inner shell 200, and the atomizing core 300 is communicated with the liquid storage cup 220. Here, it should be noted that the liquid storage cup 200 may be a liquid storage structure enclosed by the inner wall of the inner housing 200; alternatively, the reservoir cup 200 may be a separate reservoir structure (not shown) disposed in the inner housing 200, such as: a reservoir, a pouch, etc., and is not limited herein.

In this embodiment, as shown in fig. 1 to 3, the atomizing core 300 includes a first heating element 310 and a second heating element 320, a first end 311 of the first heating element 310 is connected to the bottom of the inner housing 200, and a second end 312 of the first heating element 310 extends into the liquid storage cup 220 to contact with the substance to be atomized. The second heating element 320 is a porous conductive heating element, the first end face 321 of the second heating element 320 is arranged at the bottom of the inner shell 200, the space between the second end face 322 opposite to the first end face 321 and the air outlet channel 210 forms an atomizing cavity 323, and a plurality of pores are distributed on the whole second heating element 320 and used for guiding liquid and circulating air.

It should be noted that the substance to be atomized has high viscosity and low fluidity, such as: solid or semi-solid substances to be atomized and the like, so that the situation that the substances to be atomized leak in the storage and transportation process of the atomizer is avoided.

Because the first heating element 310 is directly contacted with the solid or semi-solid substance to be atomized in the liquid storage cup 220, the heat in the first heating element 310 can directly heat the solid or semi-solid substance to be atomized, so that the solid or semi-solid substance to be atomized can be rapidly converted into the liquid substance to be atomized with low viscosity and higher fluidity. Therefore, the liquid substance to be atomized can rapidly permeate into the second heating element 320 for atomization, so that the atomizing core 300 can generate more smoke in unit time, and the smoking taste of the user is effectively improved.

The utility model provides a technical scheme is connected the setting through the first end 311 with first heating body 310 and the bottom of interior casing 200, and the second end 312 of first heating body 310 extends to and contacts with the material of waiting to atomize in the stock solution cup 220 for first heating body 310 can carry out direct contact with the material of waiting to atomize in the stock solution cup 220, thereby treats the material of atomizing and heats through first heating body 310. Thus, when the first heating body 310 heats the solid or semi-solid substance to be atomized, the heat can be directly conducted to the solid or semi-solid substance to be atomized, so that the heat conduction process is shortened, the preheating time of the substance to be atomized is shortened, and the solid or semi-solid substance to be atomized can be rapidly converted into the liquid substance to be atomized. And because the heat on the first heat-generating body 310 is directly conducted to the solid or semi-solid substance to be atomized, the loss of heat in the conduction process can be reduced, and the energy consumption of the first heat-generating body 310 is reduced.

In addition, after the first heating element 310 rapidly converts the solid or semisolid substance to be atomized into the liquid substance to be atomized, the liquid substance to be atomized can rapidly permeate into the second heating element 320 for atomization due to low viscosity and high fluidity of the liquid substance to be atomized, so that the atomizing core 300 can generate more smoke in unit time, the smoking taste of a user is effectively improved, and the atomizing core 300 can continuously maintain the atomized liquid converted into the liquid state, so that the risk of insufficient liquid dry burning of the atomizing core 300 in the using process can be effectively reduced.

Further, in this embodiment, the entire outer wall of the inner housing 200 is spaced apart from the inner wall of the outer housing 100, and at this time, an air outlet channel 210 is formed between the inner wall of the outer housing 100 and the outer wall of the inner housing 200, and the air outlet channel 210 is an annular air outlet channel; or, two short sides or two long sides of the inner housing 200 are spaced apart from the inner wall of the outer housing 100, and at this time, two air outlet channels 210 (as shown in fig. 2) are formed between the inner wall of the outer housing 100 and the outer wall of the inner housing 200; alternatively, only one air outlet channel 210 may be formed between an inner wall of the inner side of the outer casing 100 and an outer wall of the inner casing 200, which is not limited herein. It should be noted that, the number of the outlet channels 210 may also be 3 or more than 3, for example, one short side of the inner casing 200 is disposed at an interval with the inner wall of the outer casing 100, one outlet channel 210 is formed between the short side of the inner casing 200 and the inner wall of the outer casing 100, and the outlet channel 210 may also be divided into a plurality of outlet channels by partition structures such as partitions.

The structure of the gas outlet channel 210 is provided with eight quincuncial doors, the gas outlet channel 210 in the embodiment is designed as shown in fig. 1 to 3, and the purpose is that smoke generated in the atomizing cavity 323 can rapidly come out from the gas outlet channels 210 on two sides of the atomizer for rapid smoking of a user, compared with the design structure which is only provided with one gas outlet channel 210, more smoke can reach the outlet of the atomizer through a shorter path, and therefore the smoking experience of the user is improved.

Further, in this embodiment, the material selected for the first heating element 310 and the connection relationship between the first heating element 310 and the second heating element 320 may include the following conditions. First, the first end 311 of the first heating element 310 and the second heating element 320 are connected in an insulated manner, and the first heating element 310 is made of an electrically and thermally conductive material, so that the first heating element 310 can directly generate heat after being electrified, and heat can be generated, and therefore a substance to be atomized can be preheated, or the substance to be atomized can be directly heated and atomized, or the substance to be atomized can be preheated and heated and atomized in different time periods. Second, the first heat generating body 310 may also be an insulating heat conductor with good heat conductivity, and after another heat generating body, for example, the second heat generating body 320 is electrified to generate heat, the first heat generating body 310 connected with the second heat generating body 320 can quickly conduct the heat on the second heat generating body 320 to the first heat generating body 310. According to the description of the second case, the first end 311 of the first heating element 310 and the first end face 321 of the second heating element 320 can be directly connected to each other, and there can be various conventional combination structures regarding the manner of the direct connection arrangement, which will not be described herein in detail. In this case, the first heating element 310 is made of a heat-conducting and non-conducting material, so that after the second heating element 320 is powered on to work and generate heat, the heat generated by the second heating element 320 can be conducted to the first heating element 310 to rapidly heat the solid or semi-solid substance to be atomized, thereby obtaining the liquid substance to be atomized with low viscosity and higher fluidity.

In the second case, the first heat generating body 310 is preferably made of an insulating material with good thermal conductivity. Specifically, in some structural designs, taking the first heat generating body 310 made of a heat conducting and electrically non-conducting material, and the first end 311 of the first heat generating body 310 and the first end face 321 of the second heat generating body 320 being connected with each other as an example, since the first end 311 of the first heat generating body 310 is connected with the bottom of the inner case 200, and the first end face 321 of the second heat generating body 320 is arranged at the bottom of the inner case 200, that is, in the present embodiment, as shown in fig. 3, the first end 311 of the first heat generating body 310 and the first end face 321 of the second heat generating body 320 are directly connected with each other. And the first heating element 310 is made of a heat-conducting and non-conducting material, and the second heating element 320 is a porous heat-conducting heating element, so that after the second heating element 320 is electrified to generate heat, the first heating element 310 is used for preheating and/or heating and atomizing a substance to be atomized by heat conducted to the first heating element 310 through the second heating element 320. In other words, the heat of the first heat generator 310 can quickly transform the solid or semi-solid substance to be atomized in contact with the first heat generator into a liquid substance to be atomized with low viscosity and higher fluidity; or, after the heat of the first heat generating body 310 rapidly converts the solid or semi-solid substance to be atomized into the liquid substance to be atomized, the liquid substance to be atomized is heated and atomized; alternatively, the substance to be atomized can be heated and atomized by the heat of the first heat generating body 310, and at this time, the substance to be atomized is a liquid atomized substance of the substance to be atomized with high viscosity and low fluidity.

It should be noted that in this embodiment, the operation mode of the second heating element 320 can be switched by adjusting the heating power of the second heating element 320, where the second heating element 320 has two operation modes, specifically including a preheating mode and a heating and atomizing mode, the preheating mode is that heat generated by electrifying and heating the second heating element 320 is conducted to the first heating element 310, so that the solid or semi-solid substance to be atomized contacting with the first heating element 310 is converted into a liquid substance to be atomized; the heating atomization mode is to heat and atomize the liquid substance to be atomized, which is conducted to the second heating element 320, so as to form aerosol which can be sucked by a user. Wherein, the heating power of the second heating element 320 in the preheating mode is less than the heating power of the second heating element 320 in the heating atomization mode.

The heat conductive and electrically nonconductive material of the first heat generating body 310 may be a ceramic material, specifically, at least one of silicon carbide, silicon oxide, aluminum oxide, and zirconium oxide, and may also be a metal, which is not limited herein. It should be noted that the first heating element 310 may be a dense ceramic body or a porous ceramic body, and the dense ceramic body is different from the porous ceramic body in that: the porous ceramic body is a ceramic structure with a pore structure inside, and the compact ceramic body is a ceramic structure without a pore structure inside.

In this embodiment, since the first heat generating body 310 is at least partially disposed in the liquid storage cup 220, so that the first heat generating body 310 is in direct contact with the substance to be atomized in the liquid storage cup 220, preferably, the first heat generating body 310 is entirely inserted into the liquid storage cup 220, so as to heat the substance to be atomized more sufficiently and rapidly. In this way, the first heating element 310 is preferably a dense ceramic body, which has a higher thermal conduction speed than the porous ceramic body, and after the substance to be atomized is heated to be a liquid substance to be atomized, the liquid substance to be atomized does not enter the first heating element 310.

Because the ceramic heating element of silicon carbide is larger than the ceramic heating element of other materials in thermal conductivity, that is, in order to increase the thermal conductivity of the first heating element 310 in this embodiment, the first heating element 310 is preferably made of a silicon carbide material, so that the thermal conductivity of the first heating element 310 is faster, that is, the heat generated after the second heating element 320 is electrified and heated can be more quickly conducted into the first heating element 310, thereby quickly preheating and/or heating and atomizing the substance to be atomized, which is in contact with the first heating element 310, reducing the preheating time, and improving the atomization effect of the atomization core.

In this embodiment, the second heat-generating body 320 is a porous conductive heat-generating body. Specifically, the porous conductive heating element 320 is a porous conductive ceramic heating element, which is a conductive ceramic structure body sintered at a high temperature and having a large number of pore structures communicating with each other in the body and also communicating with the surface of the material. The material of the porous conductive ceramic heating body may be a mixture of at least one of silicon carbide, silicon oxide, aluminum oxide, and zirconium oxide with a conductive powder, and the material of the conductive powder may be at least one of titanium nitride, zirconium nitride, titanium carbonitride, titanium carbide, zirconium carbide, thallium carbide, hafnium carbide, titanium boride, zirconium boride, thallium boride, hafnium boride, molybdenum silicide, and tungsten carbide.

In order to increase the heat conductivity of the second heat-generating body 320, the second heat-generating body 320 is also preferably a ceramic heat-generating body made of a silicon carbide material so that the heat conduction between the first heat-generating body 310 and the second heat-generating body 320 is faster. Alternatively, the first heat generating body 310 and the second heat generating body 320 are co-fired into one body.

Further, as shown in fig. 1 to 3, the atomizing core 300 further includes a pair of electrodes 330, and the electrodes 330 may include a positive electrode and a negative electrode, which are electrically connected to the second end face 312 of the second heat-generating body 320, respectively. The other ends of the positive and negative electrodes are electrically connected to a main power supply (not shown) so that a power supply path is formed among the electrode 330, the second heating element 320, and the main power supply, and the second heating element 320 is electrically heated.

Alternatively, the electrode 330 may be made of metal. For example, the metal material may specifically include, but is not limited to, copper, aluminum, silver, etc., and in this case, the electrode 330 may be fixed on the second end 312 of the second heating element 320 by welding.

The material of the electrode 330 may be conductive ceramic. For example, the material of the electrode 330 may be a mixture of at least one of silicon carbide, silicon oxide, aluminum oxide, and zirconium oxide and a conductive powder, and the material of the conductive powder may be at least one of titanium nitride, zirconium nitride, titanium carbonitride, titanium carbide, zirconium carbide, thallium carbide, hafnium carbide, titanium boride, zirconium boride, thallium boride, hafnium boride, molybdenum silicide, and tungsten carbide. In specific implementation, the electrode 330 may be made of the same material as the second heating element 320 and co-sintered and molded; alternatively, the electrode 330 is formed by sintering separately a material different from that of the second heating element 320 and then co-sintering, but the present application is not limited thereto.

When the electrode 330 and the second heating element 320 both adopt conductive ceramic materials, the difference between the two is as follows: the resistivity of the ceramic electrode 200 is smaller than that of the conductive ceramic heating element 100, and the resistivity of the ceramic electrode 200 and that of the conductive ceramic heating element 100 can be adjusted by changing the mass ratio of the zirconia material and the titanium nitride material, which is not limited herein.

Since the ceramic heating element made of alumina has a smaller thermal conductivity than the ceramic heating element made of other materials or metals, that is, the electrode 330 in this embodiment is preferably made of alumina material, so as to reduce the thermal conductivity of the electrode 330, in this case, the heat generated by the second heating element 320 after being heated by electricity is more conducted into the first heating element 310.

Of course, in this embodiment, the second heating element 320 may further include a porous body (not shown) and a heating element (not shown) connected to the porous body, in which case, the heating element is connected to the second end surface 322 of the second heating element 320 (i.e., the porous body), and the electrode 330 is electrically connected to the heating element on the second end surface 322 of the second heating element 320. The porous body is porous ceramic, porous carbon fiber, porous quartz, diatomite, or the like, and the heating element may be a heating structure such as a heating net, a heating wire, or a heating sheet, which is not limited herein.

In other structural designs, the atomizing core 300 may include 4 electrodes, which are two positive electrodes and two negative electrodes, wherein 1 positive electrode and 1 negative electrode are electrically connected to the second end surface 322 of the second heat-generating body 320, and the other positive electrode and the other negative electrode are electrically connected to the first end 311 and the second end 312 of the first heat-generating body 310. That is, two current paths may be formed among the 4 electrodes, the first heating element 310 and the second heating element 320, so that both the first heating element 310 and the second heating element 320 may generate heat.

Alternatively, the atomizing core 300 may include 3 electrodes, at least one of which is a negative electrode and at least one of which is a positive electrode, the 3 electrodes being electrically connected to the first and second heaters 310 and 320, respectively, so that the first and second heaters 310 and 320 form two separately controllable parallel circuits.

Further, the atomizer further comprises a suction nozzle 14, the suction nozzle 14 is connected to one end of the inner housing 200 far away from the atomizing core 300, and an inner space of the suction nozzle 14 is communicated with the air outlet channel 210, so that the smoke in the air outlet channel 210 can be conducted to the suction nozzle 14 for the user to suck. Specifically, at least one air outlet 141 is disposed on the suction nozzle 14, and the air outlet 141 is used for communicating the air outlet channel 210 with the external environment, so that the smoke in the air outlet channel 210 can be conducted to the outside through the air outlet 141.

In this embodiment, the second collecting cotton 15 is disposed in the suction nozzle 14, and is used for collecting the condensed liquid drops formed by condensing the smoke when the smoke contacts the inner wall of the suction nozzle 14 with a lower temperature, so that the condensed liquid drops are not sucked into the oral cavity of the user from the suction nozzle 14, and the experience of the user is poor.

Based on the above-mentioned embodiment, as shown in fig. 1, 2, 5 and 6, the inner housing 200 is further provided with a first mounting hole 230 (see fig. 5) communicating with the liquid storage cup 220.

Wherein, a supporting plate 143 for supporting the mounting post 142 is further provided in the suction nozzle 14 to reinforce the strength of the mounting post 142.

Before the first sealing member 500 seals the upper end of the liquid storage cup 220, the liquid substance to be atomized needs to be injected into the liquid storage cup 220, and then the first sealing member 500 is inserted into the first mounting hole 240, that is, the first sealing member 500 is inserted into the upper end of the liquid storage cup 220. At this moment, in the process that the first sealing element 500 is inserted into the first mounting hole 240, the first sealing element 500 presses the external air into the liquid storage cup 220, so that the air pressure in the liquid storage cup 220 is increased, which results in the reduction of the negative pressure in the liquid storage cup 220 relative to the external air pressure or the atmospheric pressure of the atomizing cavity 323, and thus, the liquid substance to be atomized injected into the liquid storage cup 200 is easily leaked into the atomizing cavity 323 along the atomizing core 300, which is not beneficial to the transportation and use of the atomizer. In view of the above technical problems that may occur, in the present embodiment, the first seal member 500 is structurally improved.

The exhaust hole 510 also has a function of: when the atomizer worked, the liquid material of treating atomizing in the stock solution cup 220 was constantly consumed, and at this moment, atmospheric pressure in the stock solution cup 220 can constantly reduce, leads to the atmospheric pressure increase of atmospheric pressure in the stock solution cup 220 for external atmospheric pressure or atomizing chamber 323, so, the liquid material of treating atomizing conducts the speed that reaches second heat-generating body 320 and will become slowly, leads to the second heat-generating body 320 to appear owing to the liquid condition of dry combustion method. In this embodiment, because the vent 510 communicates with the inner space of the suction nozzle 14, when the air pressure in the liquid storage cup 220 can be continuously reduced, the air return to the liquid storage cup 220 through the inner space of the suction nozzle 14 and the vent 510 of the external air, so that the air pressure in the liquid storage cup 220 is increased, thereby maintaining the balance between the air pressure in the liquid storage cup 220 and the external atmospheric pressure or the atmospheric pressure of the atomizing cavity 323, and ensuring that the liquid substance to be atomized can be continuously, rapidly and smoothly conducted to the second heat-generating body 320 for heating and atomizing.
