[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] like Figure 1-Figure 9 As shown, an embodiment of the present application provides an electronic atomizer, including a main unit 2 and an oil filling device 1 connected to the main unit 2, wherein a main oil chamber 201 for providing oil to an atomizing assembly 202 is provided in the main unit 2; the oil filling device 1 includes a storage chamber 101, an intermediate chamber 102 and a movable part 105; the storage chamber 101 is used to store standby oil; the intermediate chamber 102 is connected to the storage chamber 101 and the main oil chamber 201, and a first valve 103 is provided between the storage chamber 101 and the intermediate chamber 102, and a second valve 104 is provided between the intermediate chamber 102 and the main oil chamber 201; the movable part 105 compresses and expands the intermediate chamber 102 through reciprocating motion; wherein, when the intermediate chamber 102 is expanded, the first valve 103 is opened and the second valve 104 is closed, so that the oil in the storage chamber 101 flows into the intermediate chamber 102; when the intermediate chamber 102 is compressed, the first valve 103 is closed and the second valve 104 is opened, so that the oil in the intermediate chamber 102 flows into the main oil chamber 201.

[0050] It should be noted that, in the main unit 2, since the aerosol formed by heating the atomizer component 202 is for use by the user, the atomizer component 202 includes a pore structure, for example, the atomizer component 202 includes a porous body and a heating body, wherein the porous body can absorb the oil in the main oil chamber 201 and flow to the heating body, and is heated and atomized by the heating body, wherein the atomizer component 202 can adopt the existing technology, and the present application does not make specific limitations, the atomizer component 202 is connected to the external environment, so when the oil enters the main oil chamber 201 from the intermediate chamber 102, the atomizer component 202 has a certain exhaust effect, so that the oil is smoothly injected into the main oil chamber 201 through the oil injection device 1.

[0051] In other embodiments, in order to avoid excessive pressure in the main oil chamber 201 when injecting liquid into the main oil chamber 201, an exhaust structure connected to the main oil chamber 201 and the external atmosphere may also be provided on the main engine 2, wherein, for example, the exhaust structure may be an exhaust hole, an exhaust channel, an exhaust groove or the like on the main engine 2 that connects the main oil chamber 201 and the external atmosphere, and a one-way valve may also be provided in the exhaust structure to exhaust air to the outside when the pressure in the main oil chamber 201 is greater than a predetermined value, thereby reducing the resistance to liquid injection, wherein the preset value may be set according to the actual air pressure, and the present application does not impose any specific restrictions.

[0052] With such arrangement, the electronic atomizer has its own oil filling device 1, and a large amount of stand-by oil is stored in the storage chamber 101. When there is a lack of oil in the main oil chamber 201 of the main unit 2, the position of the movable part 105 is adjusted to compress and expand the intermediate chamber 102, thereby achieving the goal of sucking part of the oil from the storage chamber 101 into the intermediate chamber 102 and injecting it into the main oil chamber 201. The main oil chamber 201 can accommodate a small amount of oil, and the user can fill the oil in small amounts and multiple times during use, thereby ensuring the quality of the oil and the length of use. In addition, the user can perform the oil filling operation very easily without the need for an additional oil bottle, thereby solving the problem in the prior art that the oil cup of the electronic atomizer cannot both ensure the quality of the oil and facilitate the user's oil filling operation.

[0053] Moreover, the volume change of the middle cavity 102 is repeated compression and expansion, and the stroke of the movable member 105 is also within a fixed range, that is, each oil injection operation is the same as the previous one.

[0054] In some embodiments, the movable member 105 can be reciprocated along the first direction under the force, and the moving position of the movable member 105 includes a first limit position in which the intermediate cavity 102 is expanded to a first volume, and a second limit position in which the intermediate cavity 102 is compressed to a second volume, the second volume being smaller than the first volume; in some possible cases, the second volume can be set to zero volume or almost zero volume. The first limit position and the second limit position constrain the moving range of the movable member 105; when the movable member 105 is at the first limit position, under the action of the limited oil volume of the first volume, the rated amount of oil is drawn from the storage cavity 101 and fills the intermediate cavity 102; when the movable member 105 is at the second limit position, the rated amount of oil is pressed from the intermediate cavity 102 into the main oil cavity 201.

[0055] Among them, Figure 1 As shown in , the first direction may be the axial direction of the electronic atomizer, or the length direction. It is understandable that in other embodiments, the first direction may also be the lateral direction of the electronic atomizer or other directions that are inclined at a certain angle relative to the axial direction, and this application does not impose any specific limitation.

[0056] With such arrangement, the reciprocating movement of the movable part 105 between the two extreme positions can achieve that each oil filling operation is to take out a rated amount of oil from the storage chamber 101 and inject it into the main oil chamber 201. The user does not need to consider the influence of the movement degree of the movable part 105 on the oil filling amount, and can directly move the movable part 105 into place once without considering the operating force. It is simple and convenient.

[0057] For the sake of appearance, the oil filling device 1 also includes an oil filling shell 108 surrounded at the outermost side, and a bracket structure fixedly connected to the oil filling shell 108 is provided in the oil filling shell 108, and the movable part 105 is assembled with the bracket structure to form a sliding connection relationship. In other embodiments, the oil filling shell 108 and the shell of the host 2 can be an integrated structure.

[0058] In another preferred embodiment, the oil injection device 1 further includes a reset member; when the movable member 105 is pressed or pulled, the movable member 105 moves from the first extreme position to the second extreme position; the reset member can move the movable member 105 from the second extreme position to the first extreme position. Specifically, in one case, when the movable member 105 is pressed, the middle cavity 102 is compressed, and the reset member can be a compression spring 106 sleeved on the circumference of the movable member 105, and the two ends of the compression spring 106 apply pressure to the movable member 105 and the support structure respectively, that is, the reset member makes the movable member 105 have a tendency to expand the middle cavity 102; in addition to the compression spring 106, elastic silicone parts, elastic metal sheets, etc. are also feasible, which can be deformed under pressure and can return to their original state after the pressure is removed. In another case, when the movable part 105 is pulled, the middle cavity 102 is expanded, and the reset part can be a tension spring arranged around the movable part 105, and the two ends of the tension spring apply tension to the movable part 105 and the support structure respectively, that is, the reset part makes the movable part 105 have a tendency to compress the middle cavity 102.

[0059] With such arrangement, the user presses the movable part 105 to trigger the movement of the position of the movable part 105, so that the middle cavity 102 is compressed. When the pressing is released, the movable part 105 moves in the opposite direction under the action of the reset member, so that the middle cavity 102 expands. The user's pulling operation on the movable part 105 is similar. In this way, the user only needs to press or pull the movable part 105 during the oil filling operation, thereby further improving the convenience of operation.

[0060] Of course, in addition to the above-mentioned reciprocating movement of the movable part 105 through external operating force and the elastic force of the reset part, the setting of the reset part is cancelled, and the movable part 105 forms a damping assembly connection with the bracket structure. The reciprocating movement of the movable part 105 is also feasible completely through the user's pressing and pulling.

[0061] In some embodiments, the oil filling device 1 also includes an oil filling shell 108 and an operating member 107; the oil filling shell 108 surrounds the storage cavity 101, the middle cavity 102 and the outside of the movable member 105; the operating member 107 is connected to the movable member 105 and extends from the oil filling shell 108 for the user to touch and apply force.

[0062] With such arrangement, the oil filling housing 108 surrounds the outermost side to protect various structures and beautify the appearance. The operating member 107 extends out from the oil filling housing 108 as an obvious operating object. The operating member 107 provides a force application position for the user to press the movable member 105 or lift the movable member 105, which is convenient for the user to operate. Figure 1-Figure 3 The case where the operating member 107 is a pressing member will be described as an example.

[0063] Of course, in addition to the above-mentioned method of setting the operating member 107, it is also feasible to not set the operating member 107, set a packaged silicone member on the oil filling housing 108 at a position opposite to the movable member 105, and the user presses the movable member 105 through the silicone member.

[0064] In a specific embodiment, the first valve 103 and the second valve 104 are both one-way valves; when the middle cavity 102 is expanded, under the action of negative pressure, the first valve 103 opens and the second valve 104 closes; when the middle cavity 102 is compressed, under the action of positive pressure, the first valve 103 closes and the second valve 104 opens.

[0065] Such a configuration, based on the one-way flow characteristic of the one-way valve, uses the positive pressure formed when the intermediate chamber 102 is compressed and the negative pressure formed when it is expanded as the power to promote the flow of oil, without the need for additional control, and is simple and reliable.

[0066] Of course, in addition to the above-mentioned one-way valve implementation method, the first valve 103 and the second valve 104 are set as two miniature solenoid valves, and the two solenoid valves are communicatively connected to the main board of the host 2, and a pressure sensor is set in the middle cavity 102. With the sensing function of the pressure sensor, it is also feasible for the main board controller to control the intermittent on and off of the solenoid valve.

[0067] In some specific embodiments, the storage chamber 101 and the intermediate chamber 102 are separated by a sealing partition 109, and the first valve 103 is arranged in the sealing partition 109; the movable part 105 is provided with an oil injection channel 110 for discharging oil from the intermediate chamber 102, the oil injection channel 110 is connected to the main oil chamber 201, and the second valve 104 is arranged in the oil injection channel 110; the oil injection device 1 also includes an intermediate cylinder 112, the intermediate cylinder 112 is a part of the bracket structure, a sealing ring is provided on the movable part 105 to be sealed and connected with the intermediate cylinder 112, and the movable part 105 can reciprocate along the intermediate cylinder 112 under force, and the sealing partition 109, the first valve 103, the intermediate cylinder 112, the movable part 105 and the second valve 104 surround the intermediate chamber 102.

[0068] With such arrangement, the intermediate cavity 102 is formed by connecting and assembling the various structures in the oil injection device 1, which is beneficial for the compact internal structure of the oil injection device 1 and the small overall volume of the oil injection device 1.

[0069] In an optional embodiment, the sealing spacer 109 is made of silicone, and the first valve 103 is a duckbill valve disposed in the sealing spacer 109, or it can be said that a duckbill valve is formed in the sealing spacer 109. The duckbill valve has a large opening on the storage chamber 101 side and is normally closed on the middle chamber 102 side. When the middle chamber 102 expands, the oil in the storage chamber 101 opens the duckbill valve due to the suction effect of negative pressure. That is, the first valve 103 is a diaphragm one-way valve made of elastic material. In this way, the diaphragm one-way valve deforms under the action of fluid pressure to control the one-way flow of the fluid, and the silicone product component integrating the sealing spacer 109 and the duckbill valve is cheap and easy to obtain, which is conducive to controlling production costs.

[0070] In another optional embodiment, the second valve 104 is an elastic member made of silicone material, and is provided with an arc surface portion 1041 protruding in the direction away from the middle cavity 102, the arc surface portion 1041 is recessed on the side of the middle cavity 102, the arc surface portion 1041 is partially disconnected but not lacking in glue, and the disconnected shape can be a cross or a Y shape. When the middle cavity 102 is compressed, the oil is squeezed and the arc surface portion 1041 is opened to flow out, so that the arc surface portion 1041 can be opened under the positive pressure of the oil in the middle cavity 102. That is, the second valve 104 is a diaphragm one-way valve made of elastic material. In this way, the diaphragm one-way valve is deformed under the action of fluid pressure to control the one-way flow of the fluid. The second valve 104 is completely made of silicone, which is cheap and easy to obtain, which is conducive to controlling production costs.

[0071] In an optional embodiment, the main engine 2 is further provided with an installation space on one side of the main oil chamber 201. The installation space can specifically be a hollow space formed in the oil filling shell 108. The installation space has a first opening and a second opening 117 at both ends in the first direction, or the oil filling shell 108 is through in the first direction. The oil filling device 1 can be installed in the installation space from the first opening, and the movable part 105 is located at one end of the installation space close to the second opening 117, and the operating part 107 extends from the second opening 117.

[0072] With such arrangement, during the process of assembling the oil filling device 1 with the host 2 to form an electronic atomizer, the various components of the oil filling device 1 are sequentially installed into the installation space from the first opening, thereby realizing a detachable connection between the oil filling device 1 and the host 2; moreover, this also provides feasibility for the integrated design of the oil filling housing 108 and the housing of the host 2, which is conducive to the smooth and flat peripheral surface of the entire electronic atomizer and high aesthetics.

[0073] In a more specific embodiment, the oil injection channel 110 is connected to the main oil chamber 201 through an oil guide tube 111. In this way, the existence of the oil guide tube 111 provides multiple possibilities for the positional relationship arrangement between the oil injection device 1 and the main machine 2. As shown in the figure, the main machine 2 and the oil injection device 1 can be arranged side by side. In combination with the installation space, a through hole connected to the main oil chamber 201 is provided in the installation space, one end of the oil guide tube 111 is connected to the through hole, and the other end is connected to the oil injection channel 110 on the movable part 105.

[0074] In an optional embodiment, the oil injection device 1 further includes a storage cylinder 113 and a piston 114. The storage cylinder 113 is part of the support structure. A sealing ring is provided around the piston 114. The piston 114 is sealed and connected to the storage cylinder 113 and cooperates with the storage cylinder 113 to form a storage chamber 101. The piston 114 moves as the oil is discharged. During assembly, the bottom of the storage cylinder 113 is facing upward, the oil is injected, and then the piston 114 is assembled.

[0075] Such an arrangement makes the storage chamber 101 a sealed chamber, thereby ensuring smooth discharge of the oil, preventing the oil from flowing back, and facilitating assembly.

[0076] Of course, in addition to the above-mentioned method, the oil filling device 1 may also include a flexible liquid storage part, in which a storage cavity 101 is provided, and the cavity wall of the storage cavity 101 is configured to change with the volume of the storage cavity 101. The flexible liquid storage part may specifically be a flexible bag or a telescopic bag. With such a configuration, the cavity wall of the storage cavity 101 may not have a fixed shape, and the cavity wall of the storage cavity 101 may deform as the unused oil is continuously discharged, so that the storage cavity 101 shrinks, and the volume of the storage cavity 101 may also change with the remaining amount of the unused oil.

[0077] It should be noted that the intermediate tube 112 and the storage tube 113 are fixedly connected or are an integrated structure, and the sealing spacer 109 is assembled between the intermediate tube 112 and the storage tube 113 .

[0078] In addition, in order to more clearly illustrate the assembly relationship inside the oil filling device 1, the bracket structure includes an upper cover 115 in addition to the intermediate cylinder 112 and the storage cylinder 113. The upper cover 115 covers the intermediate cylinder 112, the movable part 105 and the operating part 107, and a part of the movable part 105 is exposed at the top of the upper cover 115, a part of the operating part 107 extends from the top of the upper cover 115, and the top of the upper cover 115 prevents the operating part 107 from falling out; moreover, a fixed inner ring cylinder 116 is provided at the center position inside the upper cover 115, the inner ring cylinder 116 is sleeved around the movable part 105, the compression spring 106 is sleeved around the movable part 105, and the two ends of the compression spring 106 are against the step surfaces of the inner ring cylinder 116 and the movable part 105, so that the compression spring 106 can apply pressure to the movable part 105 and the inner ring cylinder 116.

[0079] Moreover, for the convenience of assembly, the movable part 105 can also be set as a split assembly structure, and the movable part 105 includes a movable body 1051 and a movable rod 1052 . The movable body 1051 is connected in the middle tube 112 , and the movable rod 1052 passes through the inner ring tube 116 and is plugged into the movable body 1051 .

[0080] Based on the above-mentioned embodiment of the electronic atomizer, it can be known that the first limit position of the movable part 105 is the position where the movable part 105 moves upward to be limited by the top of the upper cover 115, and the second limit position of the movable part 105 is the position where the movable part 105 moves downward to contact the sealing spacer 109.
