[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In this utility model, terms such as "first," "second," and the like are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of various embodiments may be combined with one another, but only if they are achievable by persons of ordinary skill in the art. If a combination of technical solutions contradicts or cannot be implemented, such combination shall be deemed non-existent and outside the scope of protection claimed by this utility model.

[0046] An embodiment of the utility model provides an atomizer. Figure 1 This is a three-dimensional exploded diagram of an embodiment of the atomizer of the present invention, with some structures hidden. Figure 2 This is a top view of an embodiment of the atomizer of the present invention, with some structures hidden. Figure 3 This is a cross-sectional schematic diagram of an embodiment of the atomizer of the present invention, with some structures hidden. Figure 6 This is a three-dimensional schematic diagram of an embodiment of the atomizer of the present invention from one perspective. Figures 1 to 3 and Figure 6 As shown, the atomizer 100 includes a nozzle 150 , an oil cup 110 , an air flow tube 120 and an atomizing assembly 130 .

[0047] The oil cup 110 includes an oil reservoir R1 and a first seal 112. The first seal 112 seals the end of the oil reservoir R1 near the suction nozzle 150. The first seal 112 is provided with a first opening H1. The suction nozzle 150 is detachably connected to the oil cup 110. When connected to the oil cup 110, the first seal 112 is enclosed and blocks the first opening H1.

[0048] The airflow tube 120 extends through the oil reservoir R1 along a first direction X. One end of the airflow tube 120, located near the mouthpiece 150 along the first direction X, has an aerosol outlet 121 for discharging aerosol. The atomizer assembly 130 is disposed within the airflow tube 120 and is in fluid communication with the oil reservoir R1 through the airflow tube 120.

[0049] In this embodiment, the first seal 112 forms the first end surface S1 of the oil cup 110 , and the first opening H1 and the mist outlet 121 are arranged on the same side of the first end surface S1 . In this embodiment, the first end surface S1 is the end of the oil cup 110 away from the atomizer assembly 130 .

[0050] Figure 4 The figure is a schematic top view of the first opening of an embodiment of the atomizer of the present invention. The first opening H1 includes a first region H11 and a second region H12. The first region H11 is used for the oil injection needle to penetrate, and the second region H12 is connected to the first region H11. The second region H12 is used to discharge gas from the oil storage chamber R1. In some embodiments, the second region H12 is located circumferentially outside the first region H11. When the oil injection needle is inserted into the first region H11, the second region H12 is still exposed outside the oil injection needle. At this time, the oil storage chamber R1 is connected to the external environment through the second region H12. When the atomizing medium is replenished and injected into the oil storage chamber R1, the second region H12 is used to discharge gas from the oil storage chamber R1 to maintain the air pressure balance in the oil storage chamber R1.

[0051] According to the atomizer 100 of the embodiment of the present invention, the oil cup 110 of the atomizer 100 includes an oil storage chamber R1 and a first sealing member 112. The first sealing member 112 is provided with a first opening H1. The suction nozzle 150 is detachably connected to the oil cup 110, and when the oil cup 110 is connected, it encloses the first sealing member 112 and blocks the first opening H1, thereby preventing the atomized medium in the oil storage chamber R1 from leaking out. The first sealing member 112 forms the first end face S1 of the oil cup 110, and the first opening H1 and the mist outlet 121 are arranged on the same side of the first end face S1, that is, the first opening H1 is equivalent to being arranged at the top of the oil cup 110, which can avoid the problem of damaging the structural design integrity of the oil storage chamber R1 caused by the first opening H1 being arranged at the bottom or side of the oil cup 110. In addition, the bottom end of the oil cup 110 is typically provided with an electrical connector 140 for electrically connecting the atomizing assembly 130 to a power supply. In the atomizer 100 of the present embodiment, the first opening H1 is equivalent to being provided at the top end of the oil cup 110. This can reduce the adverse effects of atomized medium leaking out of the oil cup 110 when replenishing the atomized medium through the first opening H1 on the electrical connector 140, thereby alleviating the problem of atomized medium contaminating and corroding the electrical connector 140. According to the atomizer 100 of the present embodiment, the first opening H1 includes a first region H11 and a second region H12. The first region H11 is used to allow the oil injection needle to penetrate. When the oil injection needle penetrates the first opening H1, the second region H12 is exposed outside the oil injection needle. The oil storage chamber R1 is maintained in communication with the external environment through the second region H12. During oil injection, the second region H12 is used to allow gas within the oil storage chamber R1 to be discharged to maintain air pressure balance within the liquid storage chamber R1. This atomizer only requires a single first opening H1 to achieve smooth oil injection. Therefore, the atomizer 100 further simplifies the structure while enabling convenient replenishment of the atomizing medium, thereby further improving the reliability of the atomizer 100 .

[0052] In some embodiments, the atomizing assembly 130 includes an oil guide member 131 and a heating member 132. The side wall of the airflow tube 120 may be provided with an oil guide hole 122 that connects the atomizing assembly 130 with the oil storage chamber R1. The atomizing medium in the oil storage chamber R1 enters the oil guide member 131 through the oil guide hole 122, and the heating member 132 can heat and atomize the atomizing assembly 130 adsorbed in the oil guide member 131 to obtain an aerosol. When used for inhalation, the airflow in the airflow tube 120 carries the aerosol to flow in the direction of the mist outlet 121. The oil guide member 131 is, for example, oil guide cotton, and the heating member 132 is, for example, a heating wire. In some specific examples, the oil guide body 131 and the heating member 132 are hollow columnar structures, wherein the hollow structure forms at least a part of the atomizing channel of the atomizing assembly 130.

[0053] In some embodiments, the second area H12 is located on at least one side of the first area H11 along the second direction Y, where the second direction Y is perpendicular to the first direction X. By way of example, the first direction X is the longitudinal direction of the atomizer 100 , and the second direction Y is the transverse direction of the atomizer, such as the width direction, but is not limited thereto.

[0054] In some specific embodiments, the second region H12 is located on one side of the first region H11 along the second direction Y. In other specific embodiments, the second region H12 is located on both sides of the first region H11 along the second direction Y.

[0055] In some embodiments, the cross-section of the first opening H1 along a direction perpendicular to the first direction X is elliptical. In this embodiment, the second region H12 is located on either side of the first region H11 along the second direction Y, with the major axis of the elliptical cross-section of the first opening H1 being parallel to the second direction Y. In this embodiment, in the cross-section of the first opening H1 along the direction perpendicular to the first direction X, the first region H11 is circular, facilitating the insertion of and accommodating the oil injection needle. The second region H12 is symmetrically located on either side of the first region H11, facilitating the uniform discharge of gas from the oil reservoir R1 through the second region H12 when the atomized medium is injected into the oil cup 110.

[0056] In some embodiments, the outer end surface of the oil cup 110 facing away from the mist outlet 121 is the second end surface S2. In some embodiments, the second end surface S2 is provided with an electrical connector 140 electrically connected to the atomization assembly 130, and the electrical connector 140 can be electrically connected to a power supply device.

[0057] The shape of the first end surface S1 is configured such that its extension in the third direction Z is greater than its extension in the second direction Y. The third direction Z is perpendicular to both the second direction Y and the first direction X. The major axis of the first opening H1 with an elliptical cross section is parallel to the second direction Y. In the above embodiment, the shape of the first end surface S1 extends longer in the third direction Z. The major axis of the first opening H1 with an elliptical cross section is parallel to the second direction Y. That is, the minor axis of the first opening H1 with an elliptical cross section is parallel to the third direction Z, in which the first end surface S1 extends longer. This makes the structure of the first end surface S1 more compact and prevents the first end surface S1 from being excessively extended overall.

[0058] Figure 5This is a perspective schematic diagram of the first sealing member in one embodiment of the atomizer of the present invention. In some embodiments, the inner surface of the first sealing member 112 facing the oil reservoir R1 is provided with an air guide groove 1121, which communicates with the second region H12. The air guide groove 1121 can extend from the location of the first opening H1 to other locations, thereby facilitating the directing of air from other locations to the second region H12 of the first opening H1. This further improves the smoothness of the discharge of air from the oil reservoir R1 when the atomizing medium is injected into the oil cup 110.

[0059] In this embodiment, the second region H12 is located on both sides of the first region H11 along the second direction Y. There are two air guide grooves 1121 , which are connected to the second region H12 in a one-to-one correspondence. In other embodiments, the number of air guide grooves 1121 may be other.

[0060] In some embodiments, the total cross-sectional area of ​​the first region H11 is greater than the total cross-sectional area of ​​the second region H12. In some embodiments, in a cross section of the first opening H1 perpendicular to the first direction X, the ratio of the total cross-sectional area of ​​the second region H12 to the total cross-sectional area of ​​the first region H11 is 3:5 to 4:5. For example, the specific ratio is 3:5, 7:10, or 4:5. By setting the ratio of the total cross-sectional area of ​​the second region H12 to the total cross-sectional area of ​​the first region H11 to this ratio, the injection rate of the atomized medium into the oil cup 110 is balanced with the exhaust rate of gas from the oil cup 110, thereby ensuring efficient injection of the atomized medium through the first opening H1.

[0061] In some embodiments, the oil cup 110 further includes an identification portion 113 provided on the first end surface S1, and the identification portion 113 indicates the first area H11. In one example, the identification portion 113 is a convex structure provided in a raised manner relative to the first end surface S1. In other embodiments, the identification portion 113 may be other structures capable of producing an identification effect, such as a recessed structure, an embedded component structure, etc. In this embodiment, the identification portion 113 is a triangular convex structure, one corner of which points to the first area H11. By providing the identification portion 113, the user can quickly identify the position of the first area H11 in the first opening H1 during the use of the atomizer 100, thereby improving the convenience of using the atomizer 100.

[0062] Figure 6 、 Figure 7 They are three-dimensional schematic diagrams of different viewing angles of an embodiment of the atomizer of the utility model, Figure 8 This is a schematic exploded perspective view of an embodiment of the atomizer of the present invention. Figure 9The figure is a perspective schematic diagram of a mouthpiece according to one embodiment of the atomizer of the present invention. In some embodiments, the mouthpiece 150 includes a support portion 151 and a blocking portion 152. The support portion 151 is removably disposed on the end of the oil reservoir R1 near the mouthpiece 150. The blocking portion 152 is disposed on the surface of the support portion 151 facing the oil reservoir R1. The blocking portion 152 matches the shape of the first opening H1, allowing it to be inserted into and block the first opening H1.

[0063] In some embodiments, the support portion 151 is in the form of a cover, capable of covering the first end surface S1. When the atomizer 100 is in normal use, the nozzle 150 is connected to the oil cup 110. The blocking portion 152 is inserted into and blocks the first opening H1, thereby preventing the atomized medium in the oil cup 110 from leaking from the first opening H1 during normal use. To replenish the atomized medium in the oil cup 110, the nozzle 150 can be separated from the oil cup 110, allowing the blocking portion 152 to move away from the first opening H1. This exposes the first opening H1 on the first end surface S1, facilitating oil filling.

[0064] In some embodiments, the first opening H1 includes two hole units connected in sequence along the first direction X, wherein the aperture of the hole unit close to the oil storage chamber R1 is larger than the aperture of the hole unit away from the oil storage chamber R1, so that a step surface is formed between the two hole units, that is, the first opening H1 is set as a stepped hole set along the first direction X, and the hole unit with a small aperture forms the above-mentioned step surface on the side facing the first end surface S1, and the blocking portion 152 is penetrated in the two hole units, and the blocking portion 152 is interference fit with at least one hole unit, and the blocking portion 152 abuts against the step surface to form an end face seal, thereby reducing the risk of leakage of the atomized medium.

[0065] As an example, the hole unit with a small aperture is an elliptical hole, and the hole unit with a large aperture is a circular hole. The elliptical hole and the circular hole are coaxially arranged, and the sealing portion 152 is passed through the elliptical hole and the circular hole, and the inner circumferential wall of the circular hole is interference fit, and the sealing portion 152 is in sealing contact with the end face of the step surface. In this way, it is only necessary to consider whether the sealing portion 152 is compatible with the part of the circular hole, without considering whether it is compatible with the elliptical hole. That is, the sealing portion 152 can be set to a cylindrical stepped shaft structure. In this way, the sealing requirements are guaranteed and the structural complexity of the sealing portion 152 can be reduced.

[0066] It is understandable that, in some alternative embodiments, the blocking portion 152 may also be interference-fitted with the two hole units at the same time, and the blocking portion 152 is also in sealing contact with the step surface.

[0067] In some embodiments, the suction nozzle 150 and the oil cup 110 are detachably connected via a snap-fit ​​structure. In other embodiments, the suction nozzle 150 and the oil cup 110 can be detachably connected via other means such as a magnetic connection and a threaded connection.

[0068] In some embodiments, the nozzle assembly 150 further includes a suction port 153 disposed on the support portion 151. The suction port 153 is spaced apart from the mist outlet 121 along the first direction X and is in air communication with the mist outlet 121. In some embodiments, the atomizer 100 further includes an oil suction member 160. The oil suction member 160 is at least partially located between the plane of the suction port 153 and the plane of the mist outlet 121, and is located on one side of the outer side of the mist outlet 121. By placing the oil suction member 160 on one side of the outer side of the mist outlet 121, the oil suction member 160 can absorb condensed liquid in the suction port 153 while saving material costs.

[0069] In some embodiments, the oil cup 110 further includes an oil cup body 111 and a second sealing member 114. The oil storage chamber R1 is provided in the oil cup body 111. The oil cup body 111 further includes a connecting chamber 1111, a first air flow channel 1113, a second air flow channel 1114, and an air inlet 1112. The connecting chamber 1111 is located on a side of the oil storage chamber R1 away from the mist outlet 121 and is configured to have a second opening. The first air flow channel 1113 and the second air flow channel 1114 are respectively provided on different sides of the oil storage chamber R1. The air inlet 1112 connects the first air flow channel 1113 with the outside of the oil cup body 111. The air flow tube 120 penetrates the connecting chamber 1111 and is connected to the first air flow channel 1113 through the connecting chamber 1111. The second air flow channel 1114 is used to connect to the air path of the air flow sensor.

[0070] In some embodiments, the second sealing member 114 includes a connecting portion 1141 and a blocking portion 1142 . The connecting portion 1141 covers the second opening, and the blocking portion 1142 is connected to the connecting portion 1141 . The blocking portion 1142 is used to separate the second airflow channel 1114 from the connecting cavity 1111 .

[0071] The airflow sensor is used to generate a signal when the user takes a suction action from the mouthpiece 150. For example, the airflow sensor is a microphone.

[0072] In some embodiments, the air inlet 1112 is located on the side of the oil cup 110. In some embodiments, the air inlet 1112 is located on the first end surface S1 of the oil cup 110. In some embodiments, the second air flow channel 1114 extends to pass through the first end surface S1. In some embodiments, the second air flow channel 1114 is directly or indirectly connected to the outer surface of the suction nozzle 150, for example, the second air flow channel 1114 is directly or indirectly connected to the suction port 153 of the suction nozzle 150. By providing the blocking portion 1142, the second air flow channel 1114 is separated from the air path of the connecting cavity 1111, thereby separating the gas path of the air flow sensor in the atomizer 100 from the gas path for carrying the aerosol generated by the atomization of the atomizing medium, thereby ensuring the effectiveness of each gas path.

[0073] In some embodiments, the blocking portion 1142 can be inserted into the second airflow channel 1114. The blocking portion 1142 is in the shape of a hollow prism, and the inner circumference of the end of the second airflow channel 1114 facing the blocking portion 1142 matches the outer circumference of the blocking portion 1142. The blocking portion 1142 has a connecting channel R2 inside for connecting the second airflow channel 1114 to the airflow sensor air path.

[0074] In this embodiment, the cross-sectional outer contour of the barrier portion 1142 is triangular. In other embodiments, the cross-sectional outer contour of the barrier portion 1142 may be a quadrilateral, a pentagon, or other shapes. Because the barrier portion 1142 is in the shape of a hollow prism, when the second seal 114 is positioned over the second opening, the prismatic barrier portion 1142 mates with the inner circumference of the second airflow channel 1114, restricting the rotational movement of the second seal 114, reducing the shaking of the second seal 114 relative to the oil cup 110, and improving the stability of the second seal 114 after installation on the oil cup 110.

[0075] The embodiment of the present utility model also provides an electronic atomization device. Figure 10 、 Figure 11 、 Figure 12 The three-dimensional schematic diagram, exploded three-dimensional schematic diagram, and cross-sectional schematic diagram of an embodiment of the electronic atomization device of the present invention are shown respectively. The electronic atomization device includes a power supply device 200 and an atomizer 100 of any of the aforementioned embodiments, and the atomizer 100 is connected to the power supply device 200.

[0076] The atomizer 100 includes a nozzle 150, an oil cup 110, an airflow tube 120, and an atomizing assembly 130. The oil cup 110 includes an oil storage chamber R1 and a first sealing member 112. The first sealing member 112 covers one end of the oil storage chamber R1 close to the nozzle 150. The first sealing member 112 is provided with a first opening H1. The nozzle 150 is detachably connected to the oil cup 110, and when the oil cup 110 is connected, the first sealing member 112 is enclosed and the first opening H1 is blocked. The airflow tube 120 is provided in the oil storage chamber R1 along the first direction X, and the airflow tube 120 has an atomizing port 121 for outputting aerosol at one end close to the nozzle 150 along the first direction X. The atomizing assembly 130 is provided in the airflow tube 120, and is connected to the liquid path of the oil storage chamber R1 through the airflow tube 120. The first seal 112 forms the first end surface S1 of the oil cup 110. The first opening H1 and the mist outlet 121 are located on the same side of the first end surface S1. In this embodiment, the first end surface S1 is the end of the oil cup 110 away from the atomizer assembly 130. The first opening H1 includes a first area H11 and a second area H12. The first area H11 is used to allow the oil injection needle to penetrate. The second area H12 connects to the first area H11 and is used to discharge gas from the oil reservoir R1.

[0077] In some embodiments, the power supply device 200 includes a housing 210, a power supply unit 220, and a circuit board 230. The power supply unit 220 and circuit board 230 are mounted within the housing 210. The housing 210 has a mounting portion 211 at one end thereof along the first direction X. The atomizer 100 can be mounted on the mounting portion 211, thereby being detachably connected to the power supply device 200. In this embodiment, the mounting portion 211 is a slot formed at one end of the housing 210 along the first direction X. The atomizer 100 is inserted into the slot to achieve connection with the power supply device 200.

[0078] The power supply 220 is, for example, a battery, which may be a secondary battery and thus rechargeable. The circuit board 230 is used to control the electrical components of the electronic atomization device. The circuit board 230 is electrically connected to the power supply 220 and to the atomization assembly 130, thereby controlling the operation of the atomization assembly 130.

[0079] In some embodiments, the power supply device 200 further includes an electrical connector 240 mounted on the mounting portion 211 of the housing 210. The electrical connector 240 is electrically connected to the circuit board 230 and is configured to electrically connect to the electrical connector 140 at the bottom of the oil cup 110. When the atomizer 100 is connected to the power supply device 200, the electrical connector 140 at the bottom of the oil cup 110 mates with the electrical connector 240, thereby electrically connecting the atomizer assembly 130 of the atomizer 100 to the circuit board 230 of the power supply device 200.

[0080] In some embodiments, the power supply device 200 further includes an airflow sensor 250, which is mounted on the mounting portion 211 of the housing 210. When the atomizer 100 is connected to the power supply device 200, the second airflow channel 1114 of the atomizer 100 communicates with the airflow sensor 250 via the connecting channel R2 within the blocking portion 1142. The airflow sensor 250 is configured to generate a signal when a user takes a puff from the mouthpiece 150. For example, the airflow sensor 250 is a microphone. The circuit board 230 is configured to control the atomization assembly 130 to activate atomization when the airflow sensor 250 senses a puff.

[0081] According to an embodiment of the present invention, the electronic atomization device includes an atomizer 100 and a power supply device 200, wherein the oil cup 110 of the atomizer 100 includes an oil storage chamber R1 and a first sealing member 112. The first sealing member 112 is provided with a first opening H1. The suction nozzle 150 is detachably connected to the oil cup 110, and when the oil cup 110 is connected, it encloses the first sealing member 112 and blocks the first opening H1, thereby preventing the atomized medium in the oil storage chamber R1 from leaking out. The first sealing member 112 forms the first end face S1 of the oil cup 110, and the first opening H1 and the mist outlet 121 are arranged on the same side of the first end face S1, that is, the first opening H1 is equivalent to being arranged at the top of the oil cup 110, which can avoid the problem of damaging the structural design integrity of the oil storage chamber R1 caused by the first opening H1 being arranged at the bottom or side of the oil cup 110. In addition, the bottom end of the oil cup 110 is typically provided with an electrical connector 140 for electrically connecting the atomizing assembly 130 to a power supply. In the atomizer 100 of the present embodiment, the first opening H1 is equivalent to being provided at the top end of the oil cup 110. This can reduce the adverse effects of atomized medium leaking out of the oil cup 110 when replenishing the atomized medium through the first opening H1 on the electrical connector 140, thereby alleviating the problem of atomized medium contaminating and corroding the electrical connector 140. According to the atomizer 100 of the present embodiment, the first opening H1 includes a first region H11 and a second region H12. The first region H11 is used to allow the oil injection needle to penetrate. When the oil injection needle penetrates the first opening H1, the second region H12 is exposed outside the oil injection needle. The oil storage chamber R1 is maintained in communication with the external environment through the second region H12. During oil injection, the second region H12 is used to allow gas within the oil storage chamber R1 to be discharged to maintain air pressure balance within the liquid storage chamber R1. This atomizer only requires a single first opening H1 to achieve smooth oil injection. Therefore, the atomizer 100 further simplifies the structure while being able to conveniently replenish the atomizing medium, thereby further improving the reliability of the atomizer 100 and the electronic atomization device.
