Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization devices, and more particularly to an atomization device. BACKGROUND

[0002] The atomization device includes an atomization main machine and an atomization assembly. The atomization assembly is usually used to contain and heat atomization liquid, and a user sucks aerosol formed after the atomization liquid in the atomization assembly is heated. The atomization main machine is used to control the atomization assembly and provide power. After the atomization liquid in the atomization assembly is consumed, it needs to be replaced. Therefore, the atomization main machine and the atomization assembly usually need to be matched to avoid problems such as short circuit, internal device damage caused by unsuitable power supply or connection structure.

[0003] In the prior art, when the atomization device detects whether the atomization assembly is matched with the atomization main machine, the internal circuit structure is complex, and a circuit is shared between the circuit elements, which causes the atomization device to fail when supplying power and detecting whether the atomization assembly is matched with the atomization main machine. At the same time, the atomization core needs to allow gas in the external environment to enter it to drive the aerosol generated thereby to be sucked by the user. In the prior art, when the air passage of the atomization device is connected to the atomization assembly and the atomization main machine, the gap between the atomization assembly and the atomization main machine caused by the detachable connection therebetween can cause gas leakage.

[0050] Various embodiments of the present application can exist in the form of a range; it should be understood that the description in the form of a range is merely for the convenience and brevity, and should not be understood as a hard limit on the scope of the present application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single values within the range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. In addition, whenever a numerical range is indicated in the present application, it refers to any cited number (fraction or integer) within the indicated range.

[0051] Please refer to Figures 1 to 6 , Figure 2 The direction of the arrow in the figure shows the flow path of the airflow in the atomization assembly 200. The present application provides an atomization device 10, which comprises:

[0052] The atomization main machine 100 is provided with a first electrode group 110 and a detection piece 120, and the detection piece 120 is provided with an air channel 20;

[0053] The atomization assembly 200 is connected to the atomization main machine 100 and is provided with a second electrode group 210 and a conductive piece 220, the second electrode group 210 is electrically connected with the first electrode group 110, for forming a power supply circuit, the detection piece 120 is inserted into the atomization assembly 200 and is connected to the conductive piece 220, for forming a detection circuit to detect the resistance of the conductive piece 220, and the air channel 20 is communicated with the atomization assembly 200 and the atomization main machine 100.

[0054] In the embodiment, the atomization host 100 and the atomization assembly 200 are electrically connected through the first electrode group 110 and the second electrode group 210, so that the atomization host 100 can control and supply power to the atomization assembly 200 to start the atomization assembly 200 to generate aerosol; after the detection piece 120 is connected to the conductive piece 220, a detection circuit is formed between the detection piece 120 and the conductive piece 220, and the resistance value of the conductive piece 220 is detected through the detection circuit. The resistance values of the conductive pieces 220 of different atomization assemblies 200 are different, so that the atomization host 100 and the atomization assembly 200 can be matched through resistance value detection.

[0055] Because the power supply circuit and the detection circuit are separated, the atomization device 10 will not fail when supplying power to generate aerosol or detecting whether the atomization assembly 200 is matched with the atomization host 100, thereby improving the use efficiency of the atomization assembly 200. In summary, the atomization host 100 and the atomization assembly 200 of the present application can confirm whether they are matched through resistance value, avoid the atomization host 100 being adapted to other models of atomization assemblies 200, and play the role of encrypting the atomization device 10; at the same time, the power supply and detection failure of the atomization assembly 200 can also be avoided.

[0056] At the same time, the detection piece 120 is also provided with the air passage 20, and the detection piece 120 is inserted into the atomization assembly 200, so that the detection piece 120 can serve as a narrow body of the air passage 20 to guide the gas from the external environment into the atomization assembly 200 from the atomization host 100, so that the aerosol generated in the atomization assembly 200 can be sucked by the user. Compared with the prior art, the air passage 20 of the present application is integrated in the detection piece 120, so that it does not occupy the remaining space in the atomization host 100 and the atomization assembly 200, and does not need to additionally add a pipeline structure with an air passage, so that the space utilization rate of the atomization device 10 is high and the production cost is low.

[0057] It should be understood that the circuit relationship between the atomization host 100 and the atomization assembly 200 can be that the resistance value of the conductive piece 220 is first detected to determine whether the atomization assembly 200 and the atomization host 100 are matched, and then the first electrode group 110 and the second electrode group 210 are connected to form a power supply circuit to supply power to the atomization assembly 200. The detection circuit can be formed separately, that is, the conductive piece 220, the detection piece 120, and the remaining structures on the atomization host 100 and the atomization assembly 200 form a complete circuit; at the same time, the detection circuit can also be formed by the conductive piece 220, the detection piece 120, and each electrode of the first electrode group 110 and the second electrode group 210, for example, as Figure 4 and Figure 5As shown, the conductive piece 220, the detection piece 120, the first negative electrode 112, and the second negative electrode 212 are connected, and thus a complete circuit is formed. Since the detection circuit only uses one electrode from the first electrode group 110 and the second electrode group 210, the detection circuit will not affect the power supply circuit during the detection process. The detection piece 120 can be a spring needle, a conductive column, or the like.

[0058] Further, referring to Figures 1 to 5 , one end of the conductive piece 220 abuts against the second electrode group 210, and the other end is connected to the detection piece 120. The conductive piece 220, the second electrode group 210, and the detection piece 120 form a detection circuit.

[0059] In this embodiment, the detection circuit can be separately formed, that is, the conductive piece 220, the detection piece 120, and the rest of the structures on the atomization host 100 and the atomization assembly 200 form a complete circuit. At the same time, the conductive piece 220 and the second electrode group 210 in the detection circuit can also directly abut against each other, so that the conductive piece 220, the second electrode group 210, and the detection piece 120 collectively form a detection circuit. At this time, the second electrode group 210 and the conductive piece 220 do not need to be connected by a wire, so the space utilization rate of the atomization assembly 200 and the atomization device is improved, and the production cost is reduced. The detection piece 120 can be a spring needle, a conductive column, or the like.

[0060] Further, referring to Figures 1 to 6 , the atomization host 100 is provided with a first contact surface 101, and the first electrode group 110 is arranged on the first contact surface 101. The atomization assembly 200 is provided with a second contact surface 201, and the second electrode group 210 and the conductive piece 220 are arranged on the second contact surface 201. The first contact surface 101 abuts against the second contact surface 201.

[0061] The conductive piece 220 is arranged on the second contact surface 201 and is provided with a conductive hole 221. At least part of the detection piece 120 is arranged in the conductive hole 221.

[0062] In this embodiment, when the first contact surface 101 and the second contact surface 201 are connected, the first electrode group 110 and the second electrode group 210 are in contact. At this time, the detection piece 120 also needs to be aligned with the conductive hole 221 and inserted into the conductive hole 221, and the atomization assembly 200 can be assembled with the atomization host 100. Therefore, the atomization host 100 and the atomization assembly 200 of the present application need to match the resistance value and the size and position of the conductive hole 221 and the detection piece 120 to be assembled, so that the atomization host 100 and the atomization assembly 200 can be matched through double matching, and the atomization device 10 is further encrypted.

[0063] Further, referring to Figure 8 and Figure 9The conductive hole 221 comprises a first sub-conductive hole 2211 and a second sub-conductive hole 2212 in sequence along a direction from the atomization main machine 100 to the atomization assembly 200, the first sub-conductive hole 2211 has a larger diameter than the second sub-conductive hole 2212, and the diameter of the second sub-conductive hole 2212 gradually decreases.

[0064] In the embodiment, when the detection piece 120 is inserted into the conductive hole 221, the detection piece 120 can enter the conductive hole 221 more easily due to the larger diameter of the first sub-conductive hole 2211 than the second sub-conductive hole 2212, and then accurately matches the conductive hole 221 through the second sub-conductive hole 2212 with a smaller diameter. In this process, the diameter relationship between the first sub-conductive hole 2211 and the second sub-conductive hole 2212 can guide the insertion of the detection piece 120 into the atomization assembly 200, thereby reducing the assembly difficulty of the atomization assembly 200 and the atomization main machine 100 and improving the assembly efficiency of the two. It should be understood that the diameter of the detection piece 120 can be matched with the diameter of the second sub-conductive hole 2212. At this time, the diameter of the second sub-conductive hole 2212 can contact the detection piece 120, thereby fixing the detection piece 120 and forming a detection circuit between the detection pieces 120.

[0065] Further, referring to Figures 8 to 9 The cross-sectional area of the detection piece 120 gradually decreases along a direction from the atomization main machine 100 to the atomization assembly 200.

[0066] The inner wall of the conductive hole 221 is provided with a first protrusion 222, and the first protrusion 222 is in interference fit with the outer side wall of the detection piece 120.

[0067] In the embodiment, the arrangement direction of the cross section of the detection piece 120 is the Z direction in the figure. Due to the gradually decreasing cross-sectional area of the detection piece 120, the end of the detection piece 120 close to the atomization assembly 200 does not directly contact the conductive piece 220 during the insertion of the detection piece 120 into the atomization assembly 200. Instead, the outer side wall of the detection piece 120 contacts the first protrusion 222 and forms a detection circuit when the detection piece 120 enters the atomization assembly 200 to a certain extent (for example, after the first contact surface 101 and the second contact surface 201 contact). The arrangement of the embodiment can avoid the formation of a circuit by the conductive piece 220 when the atomization assembly 200 and the atomization main machine 100 are not assembled, so as to avoid the user being electrocuted due to the accidental contact of the circuit.

[0068] Further, referring to Figure 1 and Figure 2 The atomization main machine 100 comprises a first shell 130 and a knob 103, the first shell 130 is provided with an accommodation cavity 240, an air inlet hole 104 and the knob 103, the air channel 20 communicates the accommodation cavity 240 and the atomization assembly 200, and the air inlet hole 104 communicates the accommodation cavity 240 and the external environment.

[0069] The toggle member 103 is movably connected to the first housing 130 and is used to shield or open the air inlet hole 104.

[0070] In this embodiment, the toggle member 103 can shield or open the air inlet hole 104 by moving itself relative to the air inlet hole 104, so as to allow the atomization device 10 to allow gas to enter to drive aerosol when needed, and avoid gas from entering to affect the stability of the internal circuit when not needed, thereby improving the service life of the atomization device 10.

[0071] Further, referring to Figure 1 and Figure 2 , the liquid suction member 270 is further arranged in the atomization assembly 200, and is arranged on the conductive member 220 in the direction from the atomization main machine 100 to the atomization assembly 200. The detection member 120 penetrates through the liquid suction member 270. The air channel 20 is provided with an air outlet hole at the end away from the atomization main machine 100. The hole of the air outlet hole is higher than the upper surface of the liquid suction member 270.

[0072] In this embodiment, when the air channel 20 is open to the inside of the atomization assembly 200, it needs to drive the aerosol to flow out, so there will be some liquid substances, such as aerosol and / or liquid carried in the air channel 20 and / or atomization liquid (used for heating to generate aerosol) stored in the atomization assembly 200, moving towards the conductive member 220 due to condensation or flow, etc. At this time, the liquid suction member 270 can prevent the above-mentioned liquid substances from contacting the conductive member 220 to cause the detection circuit to be short-circuited. At the same time, when the hole of the air outlet hole is higher than the upper surface of the liquid suction member 270, the liquid substances absorbed in the liquid suction member 270 will be difficult to flow into the air channel 20 from the air outlet hole, thereby being able to avoid the gas in the air channel 20 being blocked by the liquid, and avoiding the liquid substances causing the detection circuit to be short-circuited.

[0073] Further, referring to Figures 11 to 12 , the detection member 120 is provided with an abutting portion 121 at the end away from the atomization main machine 100. The conductive member 220 is located on the movement path of the detection member 120 and abuts against the abutting portion 121.

[0074] The atomization main machine 100 is provided with a first magnetic attraction member 102, and the atomization assembly 200 is provided with a second magnetic attraction member 202. The first magnetic attraction member 102 and the second magnetic attraction member 202 are magnetically attracted and connected.

[0075] In this embodiment, since the conductive member 220 is located on the movement path of the detection member 120, when the atomization assembly 200 and the atomization main machine 100 are assembled, the abutting portion 121 will abut against the conductive member 220, thereby naturally realizing the electrical connection between the conductive member 220 and the detection member 120, and improving the connection stability and connection efficiency of the conductive member 220 and the detection member 120.

[0076] Further, referring to Figures 11 to 12 , the side wall of the detection piece 120 is provided with a through hole 122 for connecting the air channel 20 and the inside of the atomization assembly 200.

[0077] In this embodiment, the through hole 122 can ensure the smooth connection of the air channel 20 between the atomization main machine 100 and the atomization assembly 200 without affecting the contact between the abutting portion 121 and the conductive piece 220.

[0078] Further, referring to Figure 4 and Figure 5 , the atomization assembly 200 is provided with a second mounting hole 203, the second electrode group 210 includes a second positive electrode 211 and a second negative electrode 212 arranged at intervals, the second positive electrode 211 is arranged in the second mounting hole 203, the second negative electrode 212 is sleeved on the second positive electrode 211, and the second negative electrode 212 is connected to the side wall of the second mounting hole 203.

[0079] The first electrode group 110 includes a first positive electrode 111 and a first negative electrode 112, the first positive electrode 111 and the first negative electrode 112 are arranged at intervals, and the first negative electrode 112 is connected to the second negative electrode 212, and the first positive electrode 111 is connected to the second positive electrode 211.

[0080] The nested design of the second positive electrode 211 and the second negative electrode 212 can increase the matching range of the first positive electrode 111 and the second positive electrode 211, that is, the first positive electrode 111 can contact the second positive electrode 211 within the annular range formed by the second positive electrode 211 to realize the connection, thereby providing a margin for the installation of the first positive electrode 111, ensuring that the installation position of the first positive electrode 111 can contact the second positive electrode 211 in most positions, and reducing the production cost of the atomization device 10.

[0081] It should be understood that the conductive piece 220 can have multiple, and the resistivity of the multiple conductive pieces 220 can be the same, at this time, when the user assembles the atomization main machine 100 and the atomization assembly 200, the power of the atomization device 10 is the same (the rate of aerosol generation or the amount of aerosol generated) after the user installs it in the right way or reversely. The resistivity of the conductive piece 220 can also be different, at this time, when the user installs it in the right way or reversely, the power of the atomization device 10 is different, thereby allowing the user to quickly adjust the power of the atomization device 10 to obtain different smoking experiences.

[0082] Further, referring to Figure 11 and Figure 12 , the atomization main machine 100 is provided with a limiting groove and a mounting hole, the mounting hole is located at the groove bottom of the limiting groove, one end of the detection piece 120 is arranged in the mounting hole, the other end extends away from the limiting groove, and the outer side wall of the detection piece 120 is provided with a limiting protrusion which is clamped in the limiting groove.

[0083] The conductive piece 220 is provided with a connecting surface on the side facing the atomization host 100, and the connecting surface abuts against the limiting protrusion.

[0084] In the embodiment, the limiting protrusion can rivet the detection piece 120 and the atomization host 100, and the limiting protrusion can be provided on the side wall of the detection piece 120, so as to improve the connection stability between the detection piece 120 and the atomization host 100. When the atomization assembly 200 and the atomization host 100 are connected through the first magnetic attraction piece 102 and the second magnetic attraction piece 202, the connecting surface will abut against the limiting protrusion, which can effectively seal the conductive hole 221, and at the same time, improve the contact area of the conductive piece 220 and the detection piece 120, so as to further improve the accuracy of the detection circuit when detecting whether the atomization assembly 200 and the atomization host 100 are matched.

[0085] Further, the conductive piece 220 is silica gel or silica gel doped with metal or rubber, and the metal is at least one selected from nickel, copper, aluminum, gold and silver; and / or,

[0086] The surface resistance value of the conductive piece 220 is less than 10 ohms.

[0087] In the embodiment, after the silica gel is doped with metal, the silica gel can have higher elasticity and smaller resistance, so as to avoid that the resistance of the detection circuit is too large to affect the detection result. When the surface resistance value of the conductive piece 220 is less than 10 ohms, the conductive piece 220 belongs to a conductive structure, can have the shielding function of the battery 400, and is convenient for detection.

[0088] Further, please refer to Figures 2 to 7 The atomization device 10 further includes a battery 400 and a circuit board 300, the first positive electrode 111 and the first negative electrode 112 are connected to the circuit board 300, the circuit board 300 is connected to the battery 400, and the circuit board 300 is used for controlling a power supply circuit and a detection circuit. The atomization assembly 200 can include a base 250 and a second shell 260, and the base 250 and the second shell 260 are combined to form a containing cavity 240. The second protrusion 251 and the atomization core 230 are arranged on the base 250.

[0089] Further, please refer to Figures 2 to 7 The length direction of the atomization core 230 is the Z direction. Figure 10 The atomization assembly 200 further includes the atomization core 230 and is provided with the containing cavity 240, and the atomization core 230 and the conductive piece 220 are located in the containing cavity 240.

[0090] The inner wall of the containing cavity 240 is provided with the second protrusion 251, the protruding direction of the second protrusion 251 is toward the length direction of the atomization core 230, the conductive piece 220 abuts against the side wall of the atomization core 230, and is provided with a positioning hole, and the second protrusion 251 is inserted into the positioning hole.

[0091] In the embodiment, the conductive piece 220 abuts against the sidewall of the atomization core 230, which can prevent the conductive piece 220 from shaking (moving in a plane perpendicular to the Z axis) in the accommodation cavity 240, thereby improving the stability of the conductive piece 220; the second protrusion 251 can also prevent the conductive piece 220 from being displaced when the atomization core 230 is installed or replaced, thereby improving the assembly efficiency of the atomization assembly 200 and the structural stability of the atomization device 10.

[0092] Further, the conductive piece 220 abuts against the sidewall of the atomization core 230 and directly contacts the electrode of the atomization core 230.

[0093] In the embodiment, since the conductive piece 220 directly contacts the atomization core 230, the electrically connecting device such as a wire can be omitted, thereby improving the space utilization of the accommodation cavity 240 and reducing the production cost of the atomization device 10. It should be understood that the conductive piece 220 and the atomization core 230 can be integrally formed, which can prevent the electrical connection between the conductive piece 220 and the electrode of the atomization core 230 from being poor in electrical property and reduce the assembly process of the conductive piece 220 and the atomization core 230, thereby improving the assembly efficiency of the atomization device 10. The conductive piece 220 and the second protrusion 251 can also be integrally formed, thereby further improving the assembly efficiency of the atomization device 10.

[0094] Further, please refer to Figures 2 to 3 , the second negative electrode 212 is provided with a first buckle 2121 at an end away from the first negative electrode 112, and the first buckle 2121 is buckled to the aperture of the second mounting hole 203; and / or,

[0095] The second negative electrode 212 is provided with a third mounting hole, and the third mounting hole includes a first sub-mounting hole 2122, a second sub-mounting hole 2123 and a third sub-mounting hole 2124 connected in sequence in a direction away from the first negative electrode 112, the hole diameters of the first sub-mounting hole 2122 and the third sub-mounting hole 2124 are greater than that of the second sub-mounting hole 2123, and the second positive electrode 211 is provided with a second buckle 2111 at an end away from the first positive electrode 111, and the second buckle 2111 is buckled to the aperture of the second sub-mounting hole 2123; and / or,

[0096] A sealing piece is further arranged between the second negative electrode 212 and the second positive electrode 211, and the sealing piece is in interference fit with the second negative electrode 212 and the second positive electrode 211.

[0097] In the embodiment, the clamping of the first buckle 2121 and the orifice of the second mounting hole 203 can avoid the second negative electrode 212 from being pulled out of the atomization assembly 200 along the Z direction in the drawing; similarly, the clamping of the second buckle 2111 and the orifice of the second sub-mounting hole 2123 can avoid the second positive electrode 211 from being pulled out of the atomization assembly 200, and because the hole diameter of the first sub-mounting hole 2122 is larger than that of the second sub-mounting hole 2123, when the first positive electrode 111 abuts against the second positive electrode 211, the orifice of the first sub-mounting hole 2122 can avoid the first positive electrode 111 from being pushed into the accommodating cavity 240 along the Z direction in the drawing. The seal between the second negative electrode 212 and the second positive electrode 211 can be a silica gel ring, which can avoid the atomization liquid in the atomization assembly 200 from leaking.
