Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an atomizer, a power supply component and an electronic atomization device. Background Art

[0002] There are dozens of carcinogens in tobacco smoke, such as tar, which is very harmful to human health. The smoke fills the air and forms secondhand smoke, which can also cause harm to the body when inhaled by people around. Therefore, smoking is prohibited in most public places. Electronic atomizers have a similar appearance and taste to ordinary cigarettes, but usually do not contain tar, suspended particles and other harmful ingredients in cigarettes. Therefore, electronic atomizers are widely used as substitutes for cigarettes.

[0003] For traditional electronic atomization devices, the suction resistance (abbreviated as suction resistance) is usually constant. When the user's required single puff volume is relatively large, the user will feel that the puffing time is long and strenuous when the suction resistance is large. When the user's required single puff volume is relatively small, the user will feel that the single puff volume is too large and cannot meet the expectation of a smaller puff volume when the suction resistance is small. Therefore, traditional electronic atomization cannot adapt to the puff volume of different users. Summary of the invention

[0004] A technical problem solved by the present invention is how to change the suction resistance of the electronic atomization device to adapt to different suction volumes.

[0005] An electronic atomization device comprises a detachably connected power supply assembly and an atomizer, wherein the power supply assembly is provided with a housing chamber for accommodating the atomizer; the atomizer has different installation positions relative to the power supply assembly, and an air guide channel is formed when the atomizer is inserted into the housing chamber, wherein the air guide channel is used to transport external gas to the atomizer, and the sizes of the air guide channels at different installation positions are different.

[0006] In one of the embodiments, at least one air inlet hole connecting the outside and the accommodating chamber is formed on the shell of the power supply assembly, and when the atomizer is inserted into the accommodating chamber, the air inlet hole is connected to the air guide channel.

[0007] In one of the embodiments, at least two grooves are formed on the shell of the atomizer, the cross-sectional dimensions of the grooves are different and are arranged at intervals along the circumference of the atomizer, and when the atomizer is inserted into the accommodating cavity, the grooves and the shell of the power supply assembly form the air guide channel.

[0008] In one of the embodiments, the cross-section of the accommodating cavity is square, the number of the grooves is four, and an air inlet hole connecting the outside and the accommodating cavity is opened on the power supply assembly. At each installation position, the air inlet hole transports external gas to the atomizer through one of the grooves.

[0009] In one of the embodiments, the atomizer includes an inserting portion. When the atomizer is inserted into the accommodating cavity, the inserting portion is located in the accommodating cavity, and the inserting portion is adapted to a shape of the accommodating cavity.

[0010] In one embodiment, the cross section of the accommodating cavity is a regular polygon or a circle.

[0011] In one of the embodiments, at each installation position, a plurality of channels are formed between the atomizer and the power supply assembly, at least one channel forms the air guide channel, and the air guide channel is isolated from other channels.

[0012] In one of the embodiments, an air intake channel is provided in the atomizer, and a cache channel connected to the air intake channel is formed between the atomizer and the power supply assembly; at each installation position, external gas enters the air intake channel through the air guide channel and the cache channel in turn.

[0013] In one embodiment, the atomizer has an end face facing the power supply assembly, the atomizer includes a first annular electrode and a second annular electrode installed on the end face, the second annular electrode is arranged around the first annular electrode, and the power supply assembly includes a first ejector pin and a second ejector pin; at different installation positions of the atomizer, the first ejector pin abuts against different parts of the first annular electrode, and the second ejector pin abuts against different parts of the second annular electrode.

[0014] An atomizer for an electronic atomization device is used to be connected to a power supply assembly of the electronic atomization device. The atomizer has different installation positions relative to the power supply assembly. After the atomizer is inserted into a receiving cavity of the power supply assembly, an air guide channel is formed between the power supply assembly and the atomizer. The air guide channel is used to transport external gas to the atomizer. The sizes of the air guide channels formed at different installation positions are different.

[0015] In one embodiment, the atomizer has an end surface facing the power supply assembly, the first electrode is a first annular electrode, the second electrode is a second annular electrode arranged around the first annular electrode, and the first annular electrode and the second annular electrode are both arranged on the end surface.

[0016] In one of the embodiments, at least two grooves are formed on the shell of the atomizer, the cross-sectional dimensions of the grooves are different and are arranged at intervals along the circumference of the atomizer, and when the atomizer is inserted into the accommodating cavity, the grooves and the shell of the power supply assembly form the air guide channel.

[0017] A power supply assembly for an electronic atomization device is used to cooperate with an atomizer. The power supply assembly includes a shell. The shell cooperates with the atomizer to have at least two installation positions. After the atomizer is connected to the shell, an air guide channel is formed between the shell and the atomizer, and the air guide channels formed at different installation positions have different sizes.

[0018] In one embodiment, the installation positions are distributed along the circumference of the shell, and after the power supply assembly and the atomizer are removed from one installation position, the power supply assembly and the atomizer can be connected at another installation position after rotating the shell around the axial direction by a predetermined angle.

[0020] In one of the embodiments, the power supply assembly further has a mounting surface facing the atomizer, and a first annular electrode and a second annular electrode are disposed on the mounting surface, and the second annular electrode surrounds the first annular electrode.

[0021] A technical effect of an embodiment of the present invention is: when the user needs a larger suction volume, the atomizer is placed in an installation position corresponding to a relatively large air guide channel, thereby reducing the flow resistance generated by the gas flowing through the relatively large air guide channel, that is, reducing the suction resistance of the electronic atomization device, and then increasing the gas flow entering the atomizer per unit time, and finally ensuring that the electronic atomization device is suitable for a relatively large suction volume. Conversely, when the user needs a smaller suction volume, the atomizer is placed in an installation position corresponding to a relatively small air guide channel, ensuring that the electronic atomization device is suitable for a relatively small suction volume. Therefore, only the installation position of the atomizer needs to be changed to change the suction resistance of the electronic atomization device to suit different suction volumes. This setting also makes the adjustment of the suction resistance and suction volume applicability simpler and more convenient, and makes full use of the existing installation structure of the atomizer and the power supply assembly, without adding other additional adjustment components, so that the structure of the electronic atomization device is more compact, which is in line with the development trend of miniaturization design of electronic atomization devices.

[0031] See also Figure 1 , Figure 2 and Figure 3The electronic atomization device 10 provided by an embodiment of the present invention is used to atomize an aerosol-generating matrix represented by a liquid, and the liquid can be oil or the like. The electronic atomization device 10 includes a power supply assembly 200 and an atomizer 100, and the power supply assembly 200 and the atomizer 100 are detachably connected. A liquid storage chamber 102 for storing liquid is provided in the atomizer 100, and the atomizer 100 includes an atomization core, and the atomization core is electrically connected to the power supply assembly 200 and can absorb liquid from the liquid storage chamber 102. The power supply assembly 200 is used to supply power to the atomization core, and the atomization core converts electrical energy into heat energy, and the heat energy atomizes the liquid cached inside the atomization core to form smoke that can be inhaled by the user.

[0032] See also Figure 2 , Figure 3 and Figure 4 , an air inhalation channel 101 is provided in the atomizer 100, and the air inhalation channel 101 can extend along the axial direction of the atomizer 100, and the user inhales smoke at the end of the air inhalation channel 101. The atomizer 100 has different installation positions relative to the power supply assembly 200. At each installation position, an air guide channel 130b is formed between the atomizer 100 and the power supply assembly 200. The air guide channel 130b is used to transport external gas to the air inhalation channel 101, and the cross-sectional size a of the air guide channel 130b at different installation positions is different. When the atomizer 100 is in a specific installation position, external gas enters the air inhalation channel 101 through the air guide channel 130b.

[0033] See also Figure 2 , Figure 3 and Figure 5 In some embodiments, a receiving chamber 220 is provided on the power assembly 200, and the atomizer 100 is inserted into the receiving chamber 220, so as to realize a detachable connection between the power assembly 200 and the atomizer 100. Specifically, the power assembly 200 includes a housing 210, a convex strip 240, a first ejector pin 251, and a second ejector pin 252. A receiving chamber 220 is provided at the end of the housing 210, and the receiving chamber 220 extends a certain length along the axial direction of the power assembly 200, and the atomizer 100 is inserted into the receiving chamber 220. The power assembly 200 has a mounting surface 230 and an inner side surface 212. The mounting surface 230 is horizontally arranged, and the inner side surface 212 is located on the housing 210. The inner side surface 212 is vertically arranged and surrounds the mounting surface 230. The mounting surface 230 and the inner side surface 212 jointly define the boundary of the receiving chamber 220. In other words, the mounting surface 230 and the inner side surface 212 jointly enclose the receiving chamber 220. The cross section of the accommodating cavity 220 is square, so that the housing 210 of the power supply assembly 200 can be a regular quadrangular prism structure. Of course, the housing 210 of the power supply assembly 200 can also be cylindrical or a regular triangular prism.

[0034] The first ejector pin 251 and the second ejector pin 252 extend in the vertical direction, and both are accommodated in the accommodating cavity 220. The first ejector pin 251 and the second ejector pin 252 protrude upwards by a certain length relative to the mounting surface 230. The first ejector pin 251 and the second ejector pin 252 are used to be electrically connected to the atomizer 100 to realize the power supply assembly 200 to supply power to the atomizer core. A sensing hole 253 can also be provided on the mounting surface 230, so that the microphone of the power supply assembly 200 can sense the negative pressure generated by the user's suction through the sensing hole 253. Therefore, when suction is used, a negative pressure is generated in the sensing hole 253, causing the microphone to send a feedback signal, and then the power supply assembly 200 supplies power to the atomizer core to atomize the liquid.

[0035] The convex strip 240 is connected to the mounting surface 230 and is located in the accommodating cavity 220. The convex strip 240 protrudes from the mounting surface 230 by a certain length in the vertical direction relative to the mounting surface 230. When the atomizer 100 is inserted into the accommodating cavity 220, the atomizer 100 abuts against the top of the convex strip 240, so that the atomizer 100, the convex strip 240 and the mounting surface 230 together form a cavity 243. The cavity 243 has only one notch 243a in its circumference. The cavity 243 can be used as a cache channel 243b for gas circulation. The cache channel 243b is directly connected to the air inhalation channel 101. In fact, the cache channel 243b can be regarded as a part of the accommodating cavity 220. In order to be applicable to the structure of the accommodation cavity 220 with a square cross section, the convex strip 240 includes two first connecting segments 241 and a second connecting segment 242, both of which are straight lines, the two first connecting segments 241 are parallel to each other and arranged at intervals, the second connecting segment 242 is perpendicular to the first connecting segment 241, one end of the second connecting segment 242 is connected to the end of one of the first connecting segments 241, and the other end of the second connecting segment 242 is connected to the end of another first connecting segment 241, so that the entire convex strip 240 forms a U-shaped structure, at which time, the cross section of the cache channel 243b is roughly rectangular. Of course, the convex strip 240 can also be located in an arc-shaped structure, etc., and the curvature of the convex strip 240 can be greater than 180°, at which time, the cross section of the cache channel 243b is roughly arc-shaped. The convex strip 240 is disposed around the sensing hole 253 , the first ejector pin 251 and the second ejector pin 252 . In other words, the convex strip 240 surrounds the sensing hole 253 , the first ejector pin 251 and the second ejector pin 252 .

[0036] The housing 210 of the power supply assembly 200 is provided with an air inlet hole 211, and the number of the air inlet hole 211 is one. Of course, the number of the air inlet holes 211 can be two or more according to the actual needs. The air inlet hole 211 penetrates the inner side surface 212 of the housing 210, so that the air inlet hole 211 can communicate with the outside and the accommodating cavity 220. At the same time, the above-mentioned notch 243a can be directly opposite to the inner side surface 212 provided with the air inlet hole 211.

[0037] In other embodiments, the accommodating cavity 220 may be provided on the atomizer 100, and the power supply assembly 200 may be inserted into the accommodating cavity 220 of the atomizer 100, so that a detachable connection between the power supply assembly 200 and the atomizer 100 may also be achieved. The cross section of the accommodating cavity 220 may be circular, or a regular polygonal structure such as a regular hexagon.

[0038] See also Figure 2 , Figure 3 and Figure 6 In some embodiments, the atomizer 100 includes an inserting portion 120 and a suction portion 110, the inhalation channel 101 is located in the inserting portion 120 and the suction portion 110, the inserting portion 120 cooperates with the accommodating chamber 220 and is located inside the accommodating chamber 220, and the suction portion 110 is located outside the accommodating chamber 220, and the user contacts the upper end of the suction portion 110 to inhale smoke from the inhalation channel 101. The lower end of the suction portion 110 has a bottom surface 111, and the bottom surface 111 is arranged toward the power supply assembly 200. The inserting portion 120 is connected to the middle part of the bottom surface 111 and protrudes a certain length relative to the bottom surface 111 in the vertical direction, and the edge portion of the bottom surface 111 forms a step surface 111a, and the step surface 111a surrounds the inserting portion 120. In other words, the insertion portion 120 covers the middle portion of the bottom surface 111, and the edge portion of the bottom surface 111 is not covered by the insertion portion 120 to form a step surface 111a. When the insertion portion 120 is completely received in the accommodating cavity 220, the step surface 111a abuts against the upper end of the housing 210, thereby positioning the installation of the atomizer 100 and forming a good sealing effect on the accommodating cavity 220.

[0039] The shape of the insertion portion 120 is adapted to the shape of the accommodating chamber 220. When the cross section of the accommodating chamber 220 is a square, the insertion portion 120 is a regular quadrangular prism structure. Therefore, the insertion portion 120 has four outer side surfaces 130. With reference to the air inlet hole 211 on the housing 210 of the power assembly 200, when the air inlet hole 211 faces one of the outer side surfaces 130, the atomizer 100 forms one installation position relative to the power assembly 200. When the air inlet hole 211 faces different outer side surfaces 130, the atomizer 100 forms different installation positions relative to the power assembly 200. Since the insertion portion 120 has four outer side surfaces 130, the atomizer 100 can form a total of four installation positions relative to the power assembly 200. In other embodiments, when the cross section of the accommodating chamber 220 is a regular hexagon, the atomizer 100 can form a total of six installation positions relative to the power assembly 200. When the cross section of the accommodating chamber 220 is a circle, the atomizer 100 can form three, four, five or even more installation positions relative to the power assembly 200. When the installation position of the atomizer 100 needs to be changed, the atomizer 100 can be directly pulled out of the accommodating chamber 220, and then the atomizer 100 is rotated relative to the power assembly 200 by a certain angle outside the accommodating chamber 220, and then the atomizer 100 is inserted into the accommodating chamber 220, so that another different outer side surface 130 can be set directly opposite the air inlet hole 211, and finally the installation position of the atomizer 100 is changed.

[0040] See also Figure 2 , Figure 4 and Figure 6, for the four outer side surfaces 130 of the insertion portion 120, each outer side surface 130 is recessed with a groove 130a, and the groove 130a extends in the vertical direction. At this time, four grooves 130a are formed on the insertion portion 120, and the four grooves 130a are arranged at intervals along the circumference of the atomizer 100. For the convenience of description, the four grooves 130a are respectively recorded as the first groove 131, the second groove 132, the third groove 133 and the fourth groove 134, and the recess depths of the first groove 131, the second groove 132, the third groove 133 and the fourth groove 134 increase, that is, the cross-sectional dimensions of the first groove 131, the second groove 132, the third groove 133 and the fourth groove 134 increase, and it is obvious that the cross-sectional dimensions of the four grooves 130a are different. When the first groove 131 is facing the air inlet hole 211 and connected to each other, the atomizer 100 is in the first installation position; when the second groove 132 is facing the air inlet hole 211 and connected to each other, the atomizer 100 is in the second installation position; when the third groove 133 is facing the air inlet hole 211 and connected to each other, the atomizer 100 is in the third installation position; when the fourth groove 134 is facing the air inlet hole 211 and connected to each other, the atomizer 100 is in the fourth installation position. In other embodiments, the outer side surface 130 of the insertion portion 120 is not recessed to form the groove 130a, and the groove 130a is formed by the inner side surface 212 of the housing 210 being recessed.

[0041] When the insertion portion 120 cooperates with the accommodating chamber 220, a certain amount of pressure is formed between the unrecessed portions of the four outer sides 130 and the inner side 212 of the housing 210, so that the insertion portion 120 forms a tight fit relationship with the accommodating chamber 220, thereby improving the stability and reliability of the installation of the atomizer 100. At the same time, the inner side 212 of the housing 210 closes the openings of the four grooves 130a, so that the four grooves 130a form four channels 130c with different cross-sectional dimensions a. In fact, the four channels 130c can be regarded as part of the accommodating chamber 220. Moreover, one of the channels 130c can form an air guide channel 130b. Since the insertion portion 120 forms a tight fit relationship with the accommodating chamber 220, the four grooves 130a can be formed into a mutually isolated relationship that is not connected to each other, and then the air guide channel 130b is not connected to other channels 130c and is isolated from each other.

[0042] See also Figure 3 and Figure 4Since the cache channel 243b is directly connected to the air inlet channel 101, and the insertion portion 120 forms a tight fit with the accommodating chamber 220, when the atomizer 100 is in the first installation position, the cache channel 243b is connected to the first groove 131 through its own notch 243a, and the cache channel 243b cannot be connected to the second groove 132, the third groove 133 and the fourth groove 134 and are isolated from each other. At this time, the first groove 131 forms the air guide channel 130b, and the external gas enters the air inlet channel 101 through the air inlet hole 211, the first groove 131 and the cache channel 243b in sequence. When the atomizer 100 is in the second installation position, the cache channel 243b is connected to the second groove 132 through its own notch 243a, and the cache channel 243b cannot be connected to the first groove 131, the third groove 133 and the fourth groove 134 and are isolated from each other. At this time, the second groove 132 forms an air guide channel 130b, and the external gas passes through the air inlet hole 211, the second groove 132 and the cache channel 243b in sequence to enter the air inlet channel 101. When the atomizer 100 is in the third installation position, the cache channel 243b is connected to the third groove 133 through its own notch 243a, and the cache channel 243b cannot be connected to the first groove 131, the second groove 132 and the fourth groove 134 and are isolated from each other. At this time, the third groove 133 forms an air guide channel 130b, and the external gas passes through the air inlet hole 211, the third groove 133 and the cache channel 243b in sequence to enter the air inlet channel 101. When the atomizer 100 is in the fourth installation position, the cache channel 243b is connected to the fourth groove 134 through its own notch 243a, and the cache channel 243b cannot be connected to the first groove 131, the second groove 132 and the third groove 133 and are isolated from each other. At this time, the fourth groove 134 forms the air guide channel 130b, and the external gas enters the air inlet channel 101 through the air inlet hole 211, the fourth groove 134 and the cache channel 243b in sequence. Therefore, the air inlet hole 211, the air guide channel 130b, the cache channel 243b and the air inlet channel 101 together form the entire air flow channel for gas circulation. Since the cross-sectional dimensions of the air inlet channel 101, the cache channel 243b and the air inlet hole 211 are constant, it is only necessary to change the cross-sectional dimension of the air guide channel 130b to adjust the cross-sectional dimension of the entire air flow channel.

[0043] When the user needs a larger suction volume, the atomizer 100 can be placed in the fourth installation position or the third installation position. Specifically, due to the large cross-sectional dimensions of the third groove 133 and the fourth groove 134, the flow resistance of the gas in the entire airflow channel can be reduced, thereby reducing the suction resistance of the entire electronic atomization device 10, and then increasing the gas flow rate entering the inhalation channel 101 per unit time, so that the user can easily obtain a larger amount of gas in a shorter time, and finally ensure that the electronic atomization device 10 is suitable for a relatively large suction volume. When the user needs a smaller suction volume, the atomizer 100 can be placed in the first installation position or the second installation position. Specifically, due to the small cross-sectional dimensions of the first groove 132 and the second groove 132, the flow resistance of the gas in the entire airflow channel can be increased, thereby increasing the suction resistance of the entire electronic atomization device 10, and then reducing the gas flow rate entering the inhalation channel 101 per unit time, so that the user can obtain a relatively small amount of gas from a unit time, and finally ensure that the electronic atomization device 10 is suitable for a relatively small suction volume.

[0044] Therefore, the cross-sectional size of the entire airflow channel can be adjusted by simply changing the installation position of the atomizer 100, thereby changing the suction resistance of the electronic atomization device 10 to adapt to different suction volumes, and ultimately satisfying the user's experience of different suction volumes. The above setting only requires pulling out the atomizer 100 and rotating it outside the power supply assembly 200 by a certain angle, and then inserting the atomizer 100 into the power supply assembly 200 to change the installation position of the atomizer 100, so that the adjustment of the suction resistance and the applicability of the suction volume is simpler and more convenient. Obviously, each installation position is distributed at intervals along the circumference of the atomizer 100. And make full use of the existing installation structure of the atomizer 100 and the power supply assembly 200, without adding other additional adjustment components, thereby saving the manufacturing cost generated by installing additional adjustment components, and at the same time eliminating the installation space occupied by the adjustment components, making the structure of the electronic atomization device 10 more compact, which is in line with the development trend of miniaturization design of the electronic atomization device 10.

[0045] See also Figure 5 , Figure 6 and Figure 7In some embodiments, the atomizer 100 has an end face 140 facing the power assembly 200, the end face 140 is located on the insertion portion 120, and the cache channel 243b is surrounded by the end face 140, the convex strip 240 and the mounting surface 230. The inhalation channel 101 passes through the end face 140 and is interconnected with the cache channel 243b. The atomizer 100 also includes a first electrode and a second electrode. At each mounting position, the first electrode and the second electrode can form an electrical connection relationship with the power assembly 200. Specifically, the first electrode is a first annular electrode 151, and the second electrode is a second annular electrode 152. Both the first annular electrode 151 and the second annular electrode 152 may be annular, and the second annular electrode 152 is arranged around the first annular electrode 151. With the radial direction of the first annular electrode 151 as a reference, the first annular electrode 151 and the second annular electrode 152 are arranged at intervals along the radial direction to prevent the first annular electrode 151 and the second annular electrode 152 from being connected to each other and causing a short circuit. The surfaces of the first annular electrode 151 and the second annular electrode 152 may also be flush with the end surface 140 of the atomizer 100. Of course, both the first electrode and the second electrode may also adopt an ejector-like structure similar to the first ejector 251 and the second ejector 252, that is, the first annular electrode 151 may be replaced by the first ejector 251, and the second annular electrode 152 may be replaced by the second ejector 252. When the atomizer 100 is located in the accommodating chamber 220, the first ejector pin 251 abuts against the first annular electrode 151, and the second ejector pin 252 abuts against the second annular electrode 152, thereby realizing the electrical connection between the atomizer 100 and the power supply assembly 200. When the atomizer 100 is in different installation positions, the first ejector pin 251 abuts against different parts of the first annular electrode 151, and the second ejector pin 252 abuts against different parts of the second annular electrode 152. Therefore, no matter how the atomizer 100 changes its installation position, the first ejector pin 251 always abuts against the first annular electrode 151, and the second ejector pin 252 always abuts against the second annular electrode 152, finally realizing a stable and reliable electrical connection between the atomizer 100 and the power supply assembly 200.
