[0069] In order to provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inside," and "outside" are based on the directions or positional relationships shown in the accompanying drawings and are constructed and operated in specific directions. They are merely for the purpose of facilitating the description of the present technical solution and do not indicate that the devices or components referred to must have specific directions. Therefore, they should not be understood as limiting the present invention.

[0070] like Figure 1-4As shown, the present invention constructs an electronic atomization device, including a power supply 14, an atomization bin atomization liquid cavity 216 for storing atomized liquid, and also includes a main control board 152 connected to the power supply 14, a heating element circuit and an atomized liquid state detection circuit. Among them, the heating element circuit includes a heating element 222, and a negative electrode connection unit and a first positive electrode connection unit connecting the heating element 222 and the main control board 152. The atomized liquid state detection circuit includes a first conductive member 226, a second conductive member 227, and the negative electrode connection unit and the second positive electrode connection unit connected to the main control board 152. A heating element atomization liquid cavity 2221 connected to the atomization bin atomization liquid cavity 216 is provided at the top of the heating element 222. The first end of the first conductive member 226 is electrically connected to the negative electrode connection unit, the first end of the second conductive member 227 is electrically connected to the second positive electrode connection unit, and the second ends of the first conductive member 226 and the second conductive member 227 are respectively arranged in the heating element atomization liquid cavity 2221. The main control board 152 is used to start and stop the operation of the heating element circuit according to the detection results of the heating element circuit and the atomized liquid state detection circuit.

[0071] In this embodiment, if Figure 2 、 Figure 3 、 Figure 5 As shown, the electronic atomization device includes an atomizer 2 and a power supply device 1 provided with a power supply 14. The negative electrode connection unit includes a first negative electrode connection member 223 provided on the atomizer 2 and a second negative electrode connection member 153 provided on the power supply device 1; the first positive electrode connection unit includes a third positive electrode connection member 224 provided on the atomizer 2 and a fourth positive electrode connection member 154 provided on the power supply device 1; and the second positive electrode connection unit includes a fifth positive electrode connection member 225 provided on the atomizer 2 and a sixth positive electrode connection member 155 provided on the power supply device 1.

[0072] When the second ends of the first conductive member 226 and the second conductive member 227 are simultaneously immersed in the atomized liquid, the atomizer 2 is connected to the power supply device 1 and powered on, and the heating element circuit and the atomized liquid state detection circuit are short-circuited, forming two sets of simultaneous short-circuit loop signals. At this time, the main control board 152 of the power supply device 1 issues a start-up instruction, starting the heating element circuit's heating operation. Conversely, when the atomizer 2 is connected to the power supply device 1 and powered on, the heating element circuit and the atomized liquid state detection circuit are open, the heating element circuit is short-circuited and the atomized liquid state detection circuit is open, or the heating element circuit is open and the atomized liquid state detection circuit is open, and the two circuits cannot simultaneously form short-circuit loop signals, the main control board 152 of the power supply device 1 issues a stop-operation instruction, stopping the heating element circuit's heating operation. In this embodiment, the open heating element circuit is caused by a poor connection between the atomizer 2 and the power supply device 1, and the open atomized liquid state detection circuit is caused by the depletion of atomized liquid in the heating element's atomizing liquid chamber 2221.

[0073] The heating element 222 of the atomizer 2 of the present invention can detect and determine the state of the atomized liquid before it generates heat, and can detect the state of the atomized liquid in real time during the atomization process, thereby solving the problem that the atomizer 2 continues to work when the atomized liquid in the atomizing liquid chamber 216 of the atomizing bin and the atomizing liquid chamber 2221 of the heating element is exhausted during the atomization operation, resulting in a dry burn smell and formaldehyde, or the bubbles generated by the gas-liquid exchange during the atomization operation of the atomizer 2 are stuck in the lower liquid ports 2213 on both sides, resulting in the atomized liquid not being able to reach the atomizing liquid chamber 2221 of the heating element and continuing to work, resulting in a dry burn smell and formaldehyde.

[0074] Specifically, if Figure 6-10 As shown, the power supply device 1 includes a housing 11 , a base assembly 15 , a power supply 14 and a charging plate 13 .

[0075] The shell 11 is a rod-shaped shell with an open end, and at least one air inlet 111 is provided on its side. In some embodiments, two opposing strip-shaped air inlets 111 are provided on its side. A groove 112 connected to the air inlet 111 is provided on the inner side of the shell 11. In some embodiments, the groove 112 is provided around the air inlet 111 and extends to the partition cavity 3. In this embodiment, the smoke delivery channel of the electronic atomization device includes an air inlet channel, an atomization chamber 228, and an air outlet channel that are connected in sequence, and the air inlet 111 and the groove 112 constitute part of the air inlet channel.

[0076] The charging plate 13 is provided with charging plate fixing holes 131 on both sides, through which screws 132 are screwed to the housing fixing holes 114 inside the housing 11. Figure 2 The charging board 13 is connected to the main control board 152 in the base assembly 15 via a wire, and is provided with a charging interface exposed outside the housing 11. In some embodiments, the charging interface is a USB interface.

[0077] The power source 14 is a battery in this embodiment, which is fixed on the upper portion of the charging plate 13 and connected to the main control board 152 of the base assembly 15 via a wire.

[0078] The base assembly 15 is disposed above the power supply 14 and includes an elastic base 151, a main control board 152, a second negative electrode connector 153, a fourth positive electrode connector 154, and a sixth positive electrode connector 155. In some embodiments, the elastic base 151 is made of silicone, and the second negative electrode connector 153, the fourth positive electrode connector 154, and the sixth positive electrode connector 155 are all pogo pins.

[0079] Specifically, the outer side surface of the elastic base 151 is connected with the inner side surface of the outer shell 11 by interference fit. The elastic base 151 of the present invention is made of silicone material, which can seal the mutually assembled parts. It uses its own elasticity to have an interference pressure contact effect on the second negative electrode connector 153, the fourth positive electrode connector 154 and the sixth positive electrode connector 155, and increase the sealing area between the outer side surface of the elastic base 151 and the inner side surface of the outer shell 11. It can also reduce the number of parts, achieve extreme simplification, stability and reliability, reduce parts cost and assembly cost, and be safe, non-toxic, odorless and non-flammable.

[0080] In this embodiment, the main control board 152 is disposed in the elastic base 151. In some implementations, such as Figure 11 As shown, a main control board slot 1511 for interference-inserting the main control board 152 is defined at the bottom of the elastic base 151 .

[0081] The top of the elastic base 151 is provided with three insertion holes, through which the second negative electrode connector 153, the fourth positive electrode connector 154, and the sixth positive electrode connector 155 are respectively inserted through the insertion holes on the top of the elastic base 151 with interference fit, and are connected to the internal main control board 152 via wires. The second negative electrode connector 153, the fourth positive electrode connector 154, and the sixth positive electrode connector 155 are used to respectively make contact and electrically connect with the first negative electrode connector 223, the third positive electrode connector 224, and the fifth positive electrode connector 225 of the atomizer 2.

[0082] In order to prevent the second negative electrode connector 153, the fourth positive electrode connector 154 and the sixth positive electrode connector 155 from falling off in the direction of force, the upper parts of the second negative electrode connector 153, the fourth positive electrode connector 154 and the sixth positive electrode connector 155 are respectively provided with a step 156, which fits with the top surface of the elastic base 151. Figure 6 and 7 shown.

[0083] In this embodiment, in order to further fix the base assembly 15, the power supply device 1 also includes a base positioning member 12, and the side of the shell 11 is also provided with at least two shell positioning holes 113, and the side of the elastic base 151 is also provided with at least two corresponding base positioning holes 1512. The base positioning member 12 passes through the shell positioning hole 113 and the base positioning hole 1512 to fix the elastic base 151.

[0084] Furthermore, to alert the user that the atomizer 2 is low on atomizer liquid or that the power supply 1 is not properly connected to the atomizer 2, the elastic base 151 and the base locating member 12 are both made of transparent material and serve as light guides. The main control board 152 is also provided with at least one indicator light 1521 corresponding to the base locating hole 1512. The indicator light 1521 emits light through the base locating hole 1512 on the transparent silicone base and guides it to the base locating member 12, producing a lighted reminder effect. In some embodiments, to achieve a lighted reminder effect on both base locating members 12, corresponding indicator lights 1521 can be provided on either side of the main control board 152. Alternatively, light guide holes 1522 can be provided on the main control board 152, allowing light emitted by the indicator light 1521 on one side to pass through the light guide holes 1522 and then through the base locating hole 1512 on the transparent silicone base to the other base locating member 12, producing a lighted reminder effect. In some embodiments, the indicator light 1521 is an LED indicator light.

[0085] In addition, if Figure 6 and 7 As mentioned above, in order to further remind the user that the atomizer 2 is low on atomizer liquid or that the power supply unit 1 is not properly connected to the atomizer 2, a vibrator groove 1515 is provided on the side of the elastic base 151, and a vibrator 1524 electrically connected to the main control board 152 is inserted therein. In some embodiments, the vibrator 1524 is a motor.

[0086] In this embodiment, if Figure 12-18 As shown, the atomizer 2 includes an atomizing chamber 21 and an atomizing assembly 22. Figure 13 As shown, the atomizer assembly 22 includes an elastic atomizer seat 221, a heating element 222, a first negative electrode connector 223, a third positive electrode connector 224, a fifth positive electrode connector 225, a first conductive member 226, and a second conductive member 227. In some embodiments, the elastic atomizer seat 221 is made of silicone, the first negative electrode connector 223, the third positive electrode connector 224, and the fifth positive electrode connector 225 are probe connectors, pogo pins, and the first conductive member 226 and the second conductive member 227 are conductive wires.

[0087] Specifically, if Figure 2 and 3 As shown, the outer side surface of the elastic atomizer seat 221 is connected with the inner side surface of the atomizer bin 21 by interference fit. The elastic atomizer seat 221 is made of silicone material, which can seal the mutually assembled parts. It uses its own elasticity to have an interference pressure contact effect on the first negative electrode connector 223, the third positive electrode connector 224, and the fifth positive electrode connector 225, and increase the sealing area between the outer side surface of the elastic atomizer seat 221 and the inner side surface of the atomizer bin 21. It can also reduce the number of parts, achieve extreme simplification, stability and reliability, reduce parts cost and assembly cost, and be safe, non-toxic, odorless, and non-flammable.

[0088] like Figure 13 As shown, the elastic atomizer seat 221 has a housing cavity 2211 for accommodating the heating element 222. The top surface of the heating element 222 is aligned with the top surface of the housing cavity 2211. In some embodiments, stepped heating element slots 2212 are formed on both sides of the housing cavity 2211. Accordingly, the heating element 222 is a convex-shaped heating element, and the heating element 222 is interference-engaged in the heating element slots 2212.

[0089] like Figure 13 and 18 As shown, the top of the heating element 222 is provided with a heating element atomizing liquid chamber 2221 that is connected to the atomizing liquid chamber 216 of the atomizing chamber 21. The top of the accommodating chamber 2211 corresponding to the opening of the heating element atomizing liquid chamber 2221 is provided with at least one lower liquid port 2213 that is connected to the atomizing liquid chamber 216 of the atomizing chamber. In some embodiments, a lower liquid port 2213 is provided at each end of the top of the accommodating chamber 2211.

[0090] like Figure 13 and 16 As shown, three insertion holes are provided at the bottom of the accommodating cavity 2211, and the first negative electrode connector 223, the third positive electrode connector 224 and the fifth positive electrode connector 225 are respectively inserted into the insertion holes at the bottom of the accommodating cavity 2211 by interference. Among them, the first negative electrode connector 223 and the third positive electrode connector 224 are in interference pressure contact with the heating element 2222 at the bottom of the heating element 222, so that it is stably conductive to form a heating element circuit loop. The first negative electrode connector 223, the third positive electrode connector 224 and the fifth positive electrode connector 225 are respectively in contact and electrically connected with the second negative electrode connector 153, the fourth positive electrode connector 154 and the sixth positive electrode connector 155 of the power supply device 1. In some embodiments, as Figure 18 As shown, the heating element 222 is a microporous ceramic body, and the heating element 2222 embedded in the bottom is a resistance steel sheet.

[0091] When a small amount of atomized liquid is used in the atomizer 2, the atomized liquid is easily supported on the top surface of the elastic atomizing seat 221. At this time, at least one liquid guide groove 2219 can be opened on the top of the side wall of the lower liquid port 2213 to play a liquid guide role. In some embodiments, the liquid guide groove 2219 is a V-shaped groove.

[0092] In order to prevent the first negative electrode connector 223, the third positive electrode connector 224, and the fifth positive electrode connector 225 from falling off in the direction of force, the upper portion of the first negative electrode connector 223 and the third positive electrode connector 224 are each provided with a step 156, which fits with the bottom surface of the accommodating cavity 2211. The lower portion of the fifth positive electrode connector 225 is provided with a first boss 2251, and the upper portion of the corresponding insertion hole of the fifth positive electrode connector 225 is provided with a second boss 2220 that contacts the first boss 2251. Figure 19shown.

[0093] The first negative electrode connector 223 and the fifth positive electrode connector 225 are respectively provided with holes for the first end of the first conductive member 226 to be connected to the first negative electrode connector 223, and the first end of the second conductive member 227 to be connected to the fifth positive electrode connector 225, and the second ends of the first conductive member 226 and the second conductive member 227 are respectively arranged in the heating element atomizing liquid cavity 2221. When there is atomizing liquid in the heating element atomizing liquid cavity 2221, an atomizing liquid state detection circuit loop is formed by simultaneous immersion.

[0094] like Figure 3 and 17 As shown, the bottom of the heating element 222 and the bottom surface of the accommodating chamber 2211 define an atomizing chamber 228. The accommodating chamber 2211 is a cavity with an open side. An air flow channel 229 communicating with the atomizing chamber 228 is defined between one side of the heating element 222 and the inner side of the atomizing chamber 21. The atomizer 2 requires gas-liquid exchange during atomization operation. The heating element 222 is a multi-microporous ceramic body inlaid with resistive steel sheets. At this time, one side of the heating element 222 is completely exposed, which facilitates gas-liquid exchange in the atomizer 2 and allows liquid to flow into the heating element atomizing liquid chamber 2221.

[0095] Accordingly, if Figure 13 As shown, two communicating holes 2214 are provided on the side of the elastic atomizing seat 221 corresponding to the opening of the heating element atomizing liquid chamber 2221, which are connected to the heating element atomizing liquid chamber 2221. The second ends of the first conductive member 226 and the second conductive member 227 pass through the communicating holes 2214 after passing through the air flow channel 229 and are bent into the heating element atomizing liquid chamber 2221. Figure 2 Furthermore, the top of the elastic atomizing seat 221 is also provided with an air flow tube 2215 that is in communication with the air flow channel 229. The air flow channel 229 and the air flow tube 2215 constitute a part of the air outlet channel.

[0096] like Figure 2 As shown, a first air outlet pipe 212 is provided in the atomizing chamber 21, and the air inlet end of the first air outlet pipe 212 is connected to the air flow pipe 2215. In some embodiments, the inner side of the first air outlet pipe 212 is interference-fitted with the outer side of the air flow pipe 2215. The air outlet end of the first air outlet pipe 212 is connected to the outside.

[0097] In this embodiment, to separate the condensate droplets from the smoke, the present invention designs a coaxial, long-short dual air pipe. Specifically, the outlet end of the first air outlet pipe 212 is provided with a second air outlet pipe 213, which is shorter than the first air outlet pipe 212. A dam 215 for collecting condensate is formed between the inner wall of the first air outlet pipe 212 and the outer wall of the second air outlet pipe 213. Therefore, the air outlet channel of the electronic atomization device includes an airflow channel 229, an airflow pipe 2215, and a tracheal cavity 214 formed by the first and second air outlet pipes 212, 213.

[0098] When the smoke passes through the first outlet pipe 212, the condensate mist droplets generated by the friction between the hot smoke and the inner wall of the first outlet pipe 212 will fill the inner wall of the first outlet pipe 212. The smoke produced by the atomization work will fill the middle of the tracheal cavity 214. During inhalation, the smoke will be suspended and drawn into the second outlet pipe 213 to flow out. The flow barrier 215 formed by the first and second outlet pipes 212, 213 will collect the condensate mist droplets and prevent them from flowing into the mouth. The coaxial long and short integrated double air pipes of the present invention can effectively separate the condensate mist droplets and smoke in the air, thereby solving the user's unpleasant experience of the bitter and spicy taste of the atomized liquid leaking into the mouth when inhaling.

[0099] like Figure 13 As shown, in order to further fix the outer side surface of the elastic atomizer seat 221 and the inner side surface of the atomizer bin 21 in an interference fit connection, at least one atomizer bin positioning hole 211 is respectively opened on both sides of the atomizer bin 21, and at least one positioning groove 2216 is respectively opened on both sides of the elastic atomizer seat 221. The atomizer 2 also includes an atomizer assembly positioning member 23 for passing through the atomizer bin positioning hole 211 and being snapped into the positioning groove 2216. In some embodiments, the atomizer assembly positioning member 23 is a positioning pin.

[0100] like Figure 2 and 3 As shown, in this embodiment, the inner side surface of the housing 11 of the power supply device 1 and the outer side surface of the atomization chamber 21 are connected by interference fit, so that the bottom end of the first negative electrode connector 223 is pre-pressed with the top end of the second negative electrode connector 153, the bottom end of the third positive electrode connector 224 is pre-pressed with the top end of the fourth positive electrode connector 154, and the bottom end of the fifth positive electrode connector 225 is pre-pressed with the top end of the sixth positive electrode connector 155, thereby connecting the atomizer 2 to the power supply device 1. In some embodiments, the outer side surface of the atomization chamber 21 is provided with ribs, which can achieve interference fit between the inner side surface of the housing 11 and the outer side surface of the atomization chamber 21.

[0101] And, as Figure 2 and 3 As shown, when the atomizer 2 is connected to the power supply device 1 , a partition cavity 3 is formed between the elastic atomizing seat 221 and the elastic base 151 , and the partition cavity 3 is communicated with the air inlet 111 and the groove 112 on the housing 11 .

[0102] The electronic atomization device also includes an air inlet channel connected to the atomization chamber 228, which includes an air inlet 111, a groove 112, a partition chamber 3 on the shell 11, and an air inlet channel opened on the elastic atomization seat 221 and connected to the atomization chamber 228 and the partition chamber 3.

[0103] In this embodiment, the inlet flow path includes an air inlet groove 2218 formed on the outer wall of the elastic atomizing seat 221 and communicating with the partition cavity 3, and an air inlet hole 2217 formed on the side wall of the elastic atomizing seat 221 and communicating with the air inlet groove 2218 and the atomizing cavity 228. The present invention provides one or more air inlet holes 2217 on the elastic atomizing seat 221 below the bottom side of the heating element 222. The air inlet holes 2217 are not directly opposite the atomizing surface of the heating element 222. This prevents the atomized liquid from being ejected into the power supply unit 1 when the heating element 222 is in operation, thereby effectively reducing damage to the power supply unit 1 caused by accumulated liquid.

[0104] The air inlet groove 2218, air inlet hole 2217, atomizing chamber 228, air flow channel 229, air flow tube 2215, and tracheal cavity 214 of the present invention form an N-shaped unidirectional airflow channel. Its advantage is that the direction of the unidirectional airflow in the atomizing chamber 228 is parallel to the atomizing surface, which can effectively reduce airflow intersection and avoid the generation of condensation liquid mist droplets due to alternating hot and cold in the atomizing chamber 228. It can also bring out more mist in a unidirectional and dead-angle-free manner, avoiding the retention of mist caused by airflow intersection, so that the heating element 222 can produce more atomization.

[0105] In this embodiment, if Figure 7 、 9 As shown in Figure 11, the power supply device 1 is also provided with a pneumatic switch, that is, an airflow sensor 1523 provided on the main control board 152, and an airflow sensor positioning groove 1513 is provided in the elastic base 151. The main control board 152 can be fixed in the elastic base 151 by the airflow sensor 1523 being interference fit in the airflow sensor positioning groove 1513. The airflow sensor 1523 is interference fit in the airflow sensor positioning groove 1513, so that it will not fall off and is airtight.

[0106] The elastic base 151 is also provided with an airflow sensing channel 1514 that is connected to the airflow sensor positioning groove 1513 and the partition cavity 3. When the atomizer 2 is connected to the power supply device 1, the airflow of the starting airflow h1 is provided to the airflow sensor 1523 through the gap between the power supply device 1 shell and the charging plate 13 socket, and then collected to the partition cavity 3 through the airflow sensing channel 1514. The airflow of the atomized airflow h2 is from the air inlet 111 and the groove 112 of the shell 11 to the partition cavity 3, and then to the atomizing cavity 228, forming a complete smoke delivery channel with the N-shaped one-way airflow channel. And further, the air inlet groove 2218 on the elastic atomizing seat 221 is directly opposite to the airflow sensing channel 1514, so that the airflow sensor 1523 is more sensitive to start when the user inhales.

[0107] By implementing the present invention, the following beneficial effects are achieved:

[0108] The present invention designs a heating element circuit and an atomizing liquid state detection circuit, so that the heating element of the atomizer can detect and judge the state of the atomizing liquid before it generates heat, and can detect the state of the atomizing liquid in real time during the atomization process, thereby solving the problems that the atomizer continues to work when the atomizing liquid in the atomizing liquid cavity of the atomizing bin and the atomizing liquid cavity of the heating element is exhausted during atomization work, resulting in a dry burning smell and formaldehyde, or bubbles generated by gas-liquid exchange during atomization work of the atomizer are stuck in the liquid lower ports on both sides, resulting in the atomizing liquid not being able to reach the atomizing liquid cavity of the heating element and continuing to work, resulting in a dry burning smell and formaldehyde.

[0109] At the same time, the present invention can seal the mutually assembled parts by designing the elastic atomizer seat and the elastic base, and use its own elasticity to have an interference pressure contact effect on the first negative electrode connector, the third positive electrode connector, the fifth positive electrode connector, the second negative electrode connector, the fourth positive electrode connector and the sixth positive electrode connector, and increase the sealing area between the outer side surface of the elastic atomizer seat and the inner side surface of the atomization bin, and increase the sealing area between the outer side surface of the elastic base and the inner side surface of the outer shell. It can also reduce the number of parts, achieve extreme simplification, stability and reliability, reduce the cost of parts and assembly costs, and be safe, non-toxic, odorless and non-flammable.

[0110] In addition, the present invention can effectively separate the condensate mist droplets and smoke in the air by designing a coaxial long and short integrated double air tube, thereby solving the user's unpleasant experience of the bitter and spicy taste of the atomized liquid leaking into the mouth when inhaling.

[0111] In addition, by designing an N-shaped one-way airflow channel, the alternating hot and cold airflow in the atomizing chamber can be effectively reduced to produce condensation droplets, and more mist can be brought out in a one-way, no-dead-angle manner, making the atomization amount of the heating element more abundant.

[0112] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
