Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to an atomizer and an electronic atomization device. Background Art

[0002] Electronic cigarettes and electronic devices used for atomizing health care drugs, therapeutic drugs, etc. can be collectively referred to as electronic atomization devices. The atomizer in the electronic atomization device usually includes a liquid storage cup and an atomization core. The liquid storage cup is used to store the substance to be atomized. The atomization core includes a liquid guide and a heating element that are interconnected. The atomization process of the atomization core is generally as follows: the substance to be atomized in the liquid storage cup first penetrates into the liquid guide with capillary pores, and then is transferred to the heating element of the atomization core for heating and evaporation, forming an aerosol that can be inhaled by the user.

[0003] At present, at room temperature, the substance to be atomized stored in the liquid storage cup of the atomizer is generally in liquid state. However, in order to avoid leakage during the storage and transportation of the atomizer, the substance to be atomized can also be in solid or semi-solid state.

[0004] However, when using a solid or semi-solid substance to be atomized, it is necessary to convert the solid or semi-solid substance to be atomized into a liquid substance to be atomized with higher fluidity through a preheating treatment to prevent dry burning due to lack of liquid in the heating element of the atomizer core, or even damage the atomizer core. There are some existing preheating treatments that add a preheating device to the periphery of the liquid storage cup. When the atomizer enters the preheating mode, the preheating device set on the periphery of the liquid storage cup starts to work, so that the solid or semi-solid substance to be atomized is heated and converted into a liquid substance to be atomized. However, since the heat generated by the preheating device is conducted from the periphery of the liquid storage cup to the shell 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 relatively slow, thereby increasing the preheating time. In addition, the heat generated by the preheating device is indirectly conducted to the solid or semi-solid substance to be atomized in the liquid storage cup, which will cause the loss of part of the heat during the conduction process, thereby increasing the energy consumption of the preheating device. Summary of the invention

[0005] The utility model aims to provide an atomizer and an electronic atomization device to solve the technical problem that when the preheating device preheats solid or semi-solid atomized material, the heat conduction process is relatively slow, thereby increasing the preheating time and increasing the energy consumption of the preheating device.

[0023] The beneficial effects of the atomizer and the electronic atomization device provided by the utility model are:

[0024] In the atomizer provided by the utility model, a preheating element is arranged in the storage chamber inside the inner shell so that the preheating element directly contacts the substance to be atomized in the storage chamber, thereby preheating the substance to be atomized through the preheating element. In this way, when the preheating element preheats the solid or semi-solid substance to be atomized in the storage chamber, the heat generated by the preheating element can be directly transferred to the solid or semi-solid substance to be atomized, thereby shortening the heat conduction process, reducing the preheating time of the substance to be atomized, and allowing the solid or semi-solid substance to be atomized to be quickly converted into a liquid substance to be atomized; in this process, since the heat on the preheating element is directly transferred to the solid or semi-solid substance to be atomized in the storage chamber, the heat loss during the conduction process can be reduced, thereby reducing the energy consumption of the preheating element.

[0025] In addition, since the preheating part includes a first preheating part, a second preheating part and a connecting part, and the first preheating part and the second preheating part are arranged relative to each other to form a gap, one end of the first preheating part and one end of the second preheating part both extend into the storage cavity and are connected as a whole through the connecting part, and the other end of the first preheating part and the other end of the second preheating part both penetrate the inner shell and are respectively sealed and connected to the inner shell, so that the first preheating part can be electrically connected to the second preheating part through the connecting part to form a current path.

After the preheating element quickly converts the solid or semi-solid substance to be atomized into a liquid substance to be atomized, the liquid substance to be atomized can quickly flow into the heating element through the first through hole and the liquid guide element for atomization due to its low viscosity and higher fluidity, so that the atomizer can produce more smoke per unit time, thereby improving the user's smoking taste. Moreover, since a steady supply of liquid substance to be atomized can be maintained around the heating element, the risk of dry burning due to lack of liquid during use of the atomizer can be effectively reduced.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] Please refer to Figure 1-4The utility model provides an atomizer, which includes an outer shell 100, an inner shell 200, a liquid guide 300, a heating element 400 and a preheating element 500. The inner shell 200 is arranged in the outer shell 100, and a storage cavity 210 for storing a substance to be atomized is arranged inside the inner shell 200, and at least one first through hole 220 is opened at the bottom of the inner shell 200. The liquid guide 300 is arranged at the bottom of the inner shell 200 and is located outside the storage cavity 210, and the liquid guide 300 is connected to the storage cavity 210 through the first through hole 220. The heating element 400 is connected to the end surface of the liquid guide 300 away from the storage cavity 210. The preheating component 500 comprises a first preheating portion 510, a second preheating portion 520 and a connecting portion 530. The first preheating portion 510 and the second preheating portion 520 are arranged relative to each other to form a gap 540. One end of the first preheating portion 510 extends into the storage cavity 210, and the other end of the first preheating portion 520 penetrates the inner shell 200 and is sealed and connected to the inner shell 200. One end of the second preheating portion 530 extends into the storage cavity 210 and is connected to one end of the first preheating portion 510 through the connecting portion 530. The other end of the second preheating portion 530 penetrates the inner shell 200 and is sealed and connected to the inner shell 200.

[0055] In some application scenarios, the atomized substance may be a substance with high viscosity and low fluidity, such as a solid or semi-solid substance, so as to avoid leakage of the atomized substance during storage and transportation of the atomizer.

[0056] In this embodiment, during specific implementation, the shape of the preheating component 500 can be flexibly set according to actual needs. For example, the preheating component 500 can be set to a sheet shape, a column shape (such as a cylindrical shape, a prism shape), as long as it can meet the use requirements. This embodiment does not make specific restrictions on this.

[0057] In this embodiment, based on the above structural design, by arranging a preheating member 500 in the storage chamber 210 inside the inner shell 200, the preheating member 500 is directly in contact with the substance to be atomized in the storage chamber 210, so that the substance to be atomized is preheated by the preheating member 500. In this way, when the preheating member 500 preheats the solid or semi-solid substance to be atomized in the storage chamber 210, the heat generated by the preheating member 500 can be directly transferred to the solid or semi-solid substance to be atomized, thereby shortening the heat conduction process, reducing the preheating time of the substance to be atomized, and enabling the solid or semi-solid substance to be atomized to be quickly converted into a liquid substance to be atomized; in this process, since the heat on the preheating member 500 is directly transferred to the solid or semi-solid substance to be atomized in the storage chamber 210, the heat loss during the conduction process can be reduced, thereby reducing the energy consumption of the preheating member.

[0058] In addition, since the preheating member 500 includes the first preheating portion 510, the second preheating portion 520 and the connecting portion 530, and the first preheating portion 510 and the second preheating portion 520 are arranged relatively spaced apart to form a gap 540, one end of the first preheating portion 510 and one end of the second preheating portion 520 both extend into the storage chamber 210 and are connected as a whole through the connecting portion 530, and the other end of the first preheating portion 510 and the other end of the second preheating portion 520 both penetrate the inner shell 200 and are respectively sealed and connected to the inner shell 200, so that the first preheating portion 510 can be connected to the second preheating portion 520 through the connecting portion 530. The two preheating parts 520 are electrically connected to form a current path. Therefore, when the preheating part 500 is working, the current can flow along the first preheating part 510, the connecting part 530 and the second preheating part 520, so that the heat will be evenly distributed on the first preheating part 510, the second preheating part 520 and the connecting part 530, and will not be concentrated in a certain part of the preheating part 500, that is, the preheating part 500 can directly and evenly generate heat as a whole, thereby improving the preheating uniformity of the preheating part 500, which is conducive to uniformly and quickly preheating the solid or semi-solid substance to be atomized into a liquid substance to be atomized. After the preheating element 500 quickly converts the solid or semi-solid substance to be atomized into a liquid substance to be atomized, the liquid substance to be atomized can quickly flow into the heating element 400 through the first through hole 220 and the liquid guide element 300 for atomization due to its low viscosity and higher fluidity, so that the atomizer can produce more smoke per unit time, thereby improving the user's smoking taste. Moreover, since a continuous supply of liquid substance to be atomized can be maintained around the heating element 400, the risk of insufficient liquid and dry burning of the atomizer during use can be effectively reduced.

[0059] Further, in some optional embodiments, the material of the preheating element 500 may be a conductive ceramic, which may be a mixture of at least one of silicon carbide, silicon oxide, aluminum oxide, and zirconium oxide and 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.

[0060] Of course, in other optional embodiments, the material of the preheating element 500 can be metal.

[0061] However, in the present embodiment, during the specific implementation, the material of the preheating element 500 is preferably conductive ceramic. Compared with the preheating element 500 made of metal material, since the conductive ceramic material itself has no odor and will not generate odor during the heating process, the liquid substance to be atomized will not carry any odor during the process of preheating the solid or semi-solid substance to be atomized into a liquid substance to be atomized by the preheating element 500 made of conductive ceramic material, thereby reducing the risk of odor generation after the liquid substance to be atomized is atomized, which is beneficial to improving the user's smoking taste.

[0062] Furthermore, if Figure 2 as well as Figures 5 to 7 As shown, the gap 540 formed by the relative spacing between the first preheating part 510 and the second preheating part 520 can effectively reduce the risk of short circuit between the first preheating part 510 and the second preheating part 520 during the power-on process. In this embodiment, it should be noted that in the specific implementation, the specific setting of the gap 540 can be flexibly set according to actual needs, as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this. For example, in some embodiments, such as Figure 6 As shown, when the preheating element 500 is in sheet form, a slit 540 penetrating the preheating element 500 may be provided on the side of the preheating element 500, that is, the first preheating portion 510 is arranged relative to the second preheating portion 520 in the thickness direction of the preheating element 500 to form the slit 540; for example, in other embodiments, Figure 7 As shown, when the preheating element 500 is in sheet form, a slit 540 penetrating the preheating element 500 may be provided on the front and back sides of the preheating element 500, that is, the first preheating portion 510 is arranged relative to the second preheating portion 520 along the width direction of the preheating element 500 to form the slit 540; for example, in some other embodiments, Figure 5 As shown, when the preheating element 500 is in a columnar shape, a gap 540 penetrating the preheating element 500 may be opened along the radial direction of the preheating element 500 , that is, the first preheating portion 510 is arranged relative to the second preheating portion 520 along the radial direction of the preheating element 500 to form the gap 540 .

[0063] For further information, please refer to Figure 2As shown, in some optional embodiments of the present invention, an insulating member 600 made of an insulating, heat-resistant and odorless material is provided in the gap 540 of the preheating member 500. With such a configuration, on the first hand, the first preheating part 510 can be insulated from the second preheating part 520 by the insulating member 600, thereby improving the insulation between the first preheating part 520 and the second preheating part 520, thereby further reducing the risk of short circuit between the first preheating part 510 and the second preheating part 520 during the power-on process; on the second hand, the overall structural strength of the preheating member 500 can be improved, which is beneficial to reducing the preheating member 500. The risk of breakage or damage during installation; on the third aspect, it can provide convenience for adding functional design to the atomizer. For example, a temperature sensor can be provided in the insulating part 600 to detect the working temperature of the preheating part 500, which can be used as a reference for designing relevant temperature control functions; on the fourth aspect, since the preheating part 500 quickly converts the solid or semi-solid substance to be atomized into a liquid substance to be atomized, the liquid substance to be atomized has a low viscosity and a higher fluidity. Therefore, the setting of the insulating part 600 can also prevent the liquid substance to be atomized from flowing out of the storage chamber 210 from the gap 540 and causing leakage.

[0064] In this embodiment, in order to prevent the liquid substance to be atomized from flowing out of the storage chamber 210 from the gap 540 and causing leakage, an insulating member 600 may be provided in the entire gap 540; or, an insulating member 600 may be provided in the gap 540 located in the storage chamber 210; or, an insulating member 600 may be provided in the gap 540 located outside the storage chamber 210; or, an insulating member 600 may be provided in both a portion of the gap 540 located in the storage chamber 210 and a portion of the gap 540 located outside the storage chamber 210, and this is not limited in this embodiment.

[0065] It should be noted that the above-mentioned insulating, heat-resistant and odorless material can be insulating ceramics, glass fibers, etc. When the material of the insulating component 600 is insulating ceramics, the insulating component 600 can be sintered together with the preheating component 500.

[0066] Further, in some optional embodiments of the present invention, combined with Figures 2 to 4 As shown, the atomizer further includes a nozzle 700, a bottom cover 800, a base 900 and a plug body 1200. The nozzle 700 is connected to one end of the outer shell 100. An air outlet channel 230 communicating with the nozzle 700 is formed between the inner circumferential wall of the outer shell 100 and the inner circumferential wall of the inner shell 200 (illustratively, as shown in FIG. Figure 2 and Figure 4As shown, the air outlet channel 230 is formed between the outer peripheral wall of the inner shell 200 and the inner peripheral wall of the inner shell 200), the bottom cover 800 is fixed to the bottom of the inner shell 200 and is located outside the storage cavity 210, and at least one air hole 810 connected to the air outlet channel 230 and at least one second through hole 820 connected to the first through hole 220 are provided on the bottom cover 800, the base 900 is connected to the other end of the outer shell 100 away from the suction nozzle 700, and an air inlet channel 910 connected to the air hole 810 is provided in the base 900, one end of the liquid guide 300 is connected to the bottom cover 800 and is arranged corresponding to each second through hole 820, the other end of the liquid guide 300 is connected to the base 900, the heating element 400 is exposed in the air inlet channel 910, and the plug body 1200 is sealed and matched with the top port of the inner shell 200.

[0067] In this embodiment, it can be understood that if Figure 2 As shown, the air inlet channel 910 on the base 900, the air hole 810 on the bottom cover 800, the air outlet channel 230 on the inner shell 200 and the inner cavity of the nozzle 700 are connected in sequence to form an air flow channel of the atomizer.

[0068] Based on the above structural design, in some application scenarios of assembling an atomizer containing a substance to be atomized, the inner shell 200 can be first set in the outer shell 100, and one end of the preheating component 500 can be set in the storage cavity 210, the other end of the preheating component 500 passes through the inner shell 200 and is sealed and connected to the inner shell 200, and then the bottom cover 800, the liquid guide component 300 and the heating component 400 are sequentially matched in the lower end of the outer shell 100, and then the base 900 is set at the lower end of the outer shell 100, and then the solid or semi-solid substance to be atomized is loaded into the storage cavity 210 of the inner shell 200 from the top port of the inner shell 200, and then the plug body 1200 is sealed and matched with the top port of the inner shell 200, and finally the nozzle 700 is installed on the upper end of the outer shell 100. The entire assembly process does not require the use of additional tools, and the assembly is very convenient.

[0069] Further, in some optional embodiments of the present invention, such as Figure 2 and 4As shown, the other end of the first preheating part 510 and the other end of the second preheating part 520 both pass through the bottom of the inner shell 200, the liquid guide 300 and the heating element 400 in sequence, and the other end of the first preheating part 510 and the other end of the second preheating part 520 are both insulated from the heating element 400 (in a specific implementation, in order to achieve mutual insulation between the other end of the first preheating part 510 and the heating element 400 and the other end of the second preheating part 520 and the heating element 400, the first preheating part 510 can be The other end of the first preheating part 510 and the other end of the second preheating part 520 are both spaced apart from the heating element 400. For example, the heating element 400 can be set as a ring structure with a through hole in the middle). Such a setting, on the one hand, can reduce the risk of short circuit between the other end of the first preheating part 510, the other end of the second preheating part 520 and the heating element 400 during power-on; on the other hand, after the other end of the first preheating part 510 and the other end of the second preheating part 520 pass through the heating element 400, it is convenient to subsequently electrically connect with the host power supply. In this embodiment, in order to facilitate the electrical connection between the first preheating part 510, the second preheating part 520, and the heating element 400 and the host power supply respectively in some application scenarios, the atomizer also includes a first electrode assembly 920 and a second electrode assembly 930 fixed on the base 900, the first electrode assembly 920 includes a first positive electrode 921 and a first negative electrode 922 arranged relatively at intervals, the second electrode assembly 930 includes a second positive electrode 931 and a second negative electrode 932 arranged relatively at intervals, one end of the first positive electrode 921 and one end of the first negative electrode 931 are respectively electrically connected to the heating element 400, the other end of the first positive electrode 921 and the other end of the first negative electrode 931 are respectively exposed from the bottom surface of the base 900, one end of the second positive electrode 922 is electrically connected to the other end of the first preheating part 510, one end of the second negative electrode 932 is electrically connected to the other end of the second preheating part 520, and the other end of the second positive electrode 922 and the other end of the second negative electrode 932 are respectively exposed from the bottom surface of the base 900. It should be noted that the other end of the first positive electrode 921, the other end of the first negative electrode 931, the other end of the second positive electrode 922, and the other end of the second negative electrode 932 can be electrically connected to the corresponding electrodes of the host power supply through electrical contact or the like. In some actual application scenarios, the heating element 400 and the preheating element 500 can be powered on to generate heat at the same time, or the preheating element 500 can be powered on to generate heat first, and then the heating element 400 can be powered on to generate heat. This embodiment does not impose any specific restrictions on this.

[0070] Further, in some optional embodiments of the present invention, combined with Figures 2 to 4As shown, the atomizer further includes a metal conductive sleeve 940 and a first metal wire 950 and a second metal wire 960 which are arranged at a relatively interval. The metal conductive sleeve 940 is sleeved on the outer wall of the other end of the first preheating part 510 and the second preheating part 520. The materials of the second positive electrode 931 and the second negative electrode 932 are both metal materials. One end of the first metal wire 950 is welded to the outer wall of the metal conductive sleeve 940, and the other end of the first metal wire 950 is welded to the second positive electrode 931. One end of the second metal wire 960 is welded to the outer wall of the metal conductive sleeve 940, and the other end of the second metal wire 960 is welded to the second negative electrode 932. In this way, by providing the metal conductive sleeve 940, the first metal wire 950 and the second metal wire 960, the convenience and reliability of the electrical connection between the second positive electrode 931 and the first preheating part 510, and between the second negative electrode 932 and the second preheating part 520 can be improved, that is, the convenience and reliability of the electrical connection between the second electrode assembly 930 and the preheating member 500 are improved.

[0071] In some optional embodiments, in order to further reduce the risk of aerosols with odors generated after the liquid substance to be atomized is atomized, the material of the liquid guide 300 may be porous ceramics, and the material of the heating element 400 may be conductive ceramics. In this way, the liquid guide 300, the heating element 400, and the preheating element 500 are all odor-free ceramic materials, so that no odor will be generated during the process of converting the solid or semi-solid substance to be atomized into the liquid substance to be atomized, and during the process of the liquid substance to be atomized flowing into the liquid guide 300 and passing through the heating element 400 for atomization, thereby further improving the user's smoking taste. Furthermore, considering that when the material of the liquid guide 300 is porous ceramics, when one end of the liquid guide 300 is connected to the bottom cover 800, the liquid guide 300 is easily damaged by collision with the bottom cover 800 due to factors such as improper installation, therefore, in this embodiment, combined with Figures 2 to 4 As shown, the atomizer also includes a liquid-conducting cotton 1000. A mounting groove 830 connected to the second through hole 820 is recessed on one side of the bottom cover 800 facing the liquid-conducting member 300. The liquid-conducting cotton 1000 is installed in the mounting groove 830 and covers each second through hole 820. One end of the liquid-conducting member 300 away from the base 900 extends into the mounting groove 830 and is in close contact with the liquid-conducting cotton 1000.

[0072] Based on the above structural design, by arranging the liquid-conducting cotton 1000 between the liquid-conducting member 300 and the bottom cover 800, on the first hand, the risk of damage to the liquid-conducting member 300 and the bottom cover 800 due to collision during installation can be reduced; on the second hand, the liquid-conducting cotton 1000 can reduce the fluidity of the atomized liquid, play a buffering role for the atomized liquid, and thus can reduce the flow rate of the atomized liquid introduced into the liquid-conducting member 300 per unit time, so that the liquid-conducting member 300 is not easy to reach a saturated state, thereby reducing the risk of leakage of the atomizer; on the third hand, when the liquid-conducting cotton 1 After absorbing the atomized liquid to a saturated state, since a certain amount of atomized liquid is stored in the liquid-conducting cotton 1000, when the user uses the atomizer to inhale, when the atomized liquid in the liquid-conducting part 300 is consumed, the atomized liquid in the liquid-conducting cotton 1000 can be replenished to the liquid-conducting part 300 in time through capillary action and atomized through the heating element 400, thereby effectively reducing the risk of the atomizer being dry-burned due to lack of liquid; Fourthly, considering that the liquid-conducting performance of the liquid-conducting part 300 made of porous ceramic material is better than that of porous materials such as fiber cotton, non-woven fabrics, and blended fibers, The liquid conducting speed is relatively poor (i.e., the liquid conducting speed is slow). Therefore, if porous ceramic is selected as the material of the liquid conducting part of the atomizer, the liquid conducting part 300 may fail to conduct the atomized liquid to the heating part 400 in time during the operation of the atomizer, resulting in the problem of lack of liquid and dry burning of the heating part 400. Based on this consideration, in this embodiment, on the basis of selecting porous ceramic as the material of the liquid conducting part 300, liquid conducting cotton 1000 is further provided, and the liquid conducting cotton 1000 is stacked on the side of the liquid conducting part 300 facing away from the heating part 400. In this way, due to the liquid conducting performance of the liquid conducting cotton 1000, the liquid conducting performance of the liquid conducting cotton 1000 is improved. The liquid conducting performance of the liquid conducting part 300 is significantly better than that of the liquid conducting part 300 made of porous ceramic material. Therefore, compared with using porous ceramic as the material of the entire liquid conducting part 300, it is beneficial to improve the liquid conducting performance of the entire atomizer. That is, under the same thickness condition, by setting the liquid conducting part of the atomizer to a composite layer structure including liquid conducting cotton 1000 and the liquid conducting part 300, compared with a single-layer structure of the liquid conducting part 300 made only of porous ceramic material, it can make up for the problem of the heating element 400 being prone to lack of liquid and dry burning when the material of the entire liquid conducting part is porous ceramic.

[0073] Further, in some optional embodiments of the present invention, such as Figures 2 to 4As shown, the atomizer also includes a seal 1100 with at least one third through hole 1110, the seal 1100 is sandwiched between the bottom of the inner shell 200 and the bottom cover 800, and the seal 1100 is sealed on the outer wall of the first preheating part 510 and the second preheating part 520, and the third through hole 1110 is respectively connected with the first through hole 220 and the second through hole 820. Such a configuration can not only ensure that the atomized liquid flows into the liquid guide part 300 from the first through hole 220, the third through hole 1110 and the second through hole 820 in sequence, so as to be atomized by the heating element 400, but also reduce the risk of leakage of the atomized liquid from the gap between the first preheating part 510 or the second preheating part 520 and the inner shell 200 and the bottom cover 800.

[0074] Correspondingly, the present invention also provides an electronic atomization device, such as Figure 8 and 9 As shown, the electronic atomization device includes a host 1 and an atomizer in any of the above embodiments. The host 1 includes a host housing 11 and a host battery 12 disposed in the host housing 11, the housing 100 is connected to the host housing 11, and the heating element 400 and the preheating element 500 are electrically connected to the host battery 12 respectively.
