Therefore, when suction is applied, a negative pressure is generated in the sensing hole 253, so that the microphone sends a feedback signal, and then the power supply assembly 200 supplies power to the atomizing core to atomize the liquid.

The protrusion 240 is connected to the mounting surface 230 and located in the receiving cavity 220, the protrusion 240 protrudes from the mounting surface 230 by a certain length in a vertical direction relative to the mounting surface 230, when the atomizer 100 is inserted into the receiving cavity 220, the atomizer 100 abuts against a top end of the protrusion 240, so that the atomizer 100, the protrusion 240 and the mounting surface 230 jointly enclose a cavity 243, the cavity 243 has only one notch 243a in a circumferential direction, the cavity 243 can be used as a buffer channel 243b for gas to flow through, the buffer channel 243b is directly communicated with the suction channel 101, in fact, the buffer channel 243b can be regarded as a part of the receiving cavity 220, in order to adapt to the receiving cavity 220 structure with a square cross section, the protrusion 240 includes two first connecting sections 241 and a second connecting section 242, the first connecting sections 241 and the second connecting section 242 are both linear, the two first connecting sections 241 are parallel to each other and are spaced, the second connecting sections 242 are perpendicular to each other, one end of the second connecting section 242 is connected to one of the first connecting section 241, the buffer section 241 is connected to the end of the first connecting section 241, the second connecting section 240 and the protrusion 240 b is located around the protrusion 240, in a circular arc shape, and the first connecting section 240 b is larger than the first connecting section 251 b, in the first connecting section 240, in a circular arc shape, in other, so that the first connecting section 35240 and the first connecting section 240 and the second connecting section 240 form a sensing structure, in the shape of the thimble structure, in the thimble structure.

The housing 210 of the power module 200 is provided with one air inlet 211, and the number of the air inlets 211 is one, but of course, the number of the air inlets 211 may be two or more according to the requirement of the actual situation. The air inlet holes 211 penetrate through the inner side surface 212 of the housing 210, so that the air inlet holes 211 can communicate the outside with the accommodating chamber 220. Meanwhile, the gap 243a may face the inner side surface 212 where the air intake hole 211 is formed.

In other embodiments, the receiving cavity 220 may be opened on the atomizer 100, and the power supply module 200 is inserted into the receiving cavity 220 of the atomizer 100, so that the power supply module 200 and the atomizer 100 can be detachably connected. The cross section of the accommodating cavity 220 may be circular, or regular polygonal structure such as regular hexagon, etc.

Referring to fig. 2, 3 and 6, in some embodiments, the atomizer 100 includes an insertion portion 120 and a suction portion 110, the air suction channel 101 is located in the insertion portion 120 and the suction portion 110, the insertion portion 120 is located in the receiving cavity 220 in cooperation with the receiving cavity 220, the suction portion 110 is located outside the receiving cavity 220, and the user contacts with the upper end of the suction portion 110 to suck the smoke in the air suction channel 101. The lower end of the suction part 110 has a bottom surface 111, the bottom surface 111 is disposed toward the power module 200, the insertion part 120 is connected to a middle portion of the bottom surface 111 and protrudes a certain length in a vertical direction with respect to the bottom surface 111, and an edge portion of the bottom surface 111 forms a stepped surface 111a, the stepped surface 111a surrounding the insertion part 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 the stepped surface 111 a. When the insertion portion 120 is completely received in the receiving cavity 220, the stepped surface 111a abuts against the upper end of the housing 210, thereby positioning the atomizer 100 and providing a good sealing effect for the receiving cavity 220.

The shape of the insertion part 120 is matched with the shape of the accommodating cavity 220, and when the cross section of the accommodating cavity 220 is square, the insertion part 120 has a regular quadrangular prism structure. Therefore, the insertion portion 120 has four outer side surfaces 130, and with reference to the air inlet holes 211 on the housing 210 of the power module 200, when the air inlet holes 211 are aligned with one of the outer side surfaces 130, the atomizer 100 forms one mounting position relative to the power module 200, and when the air inlet holes 211 are aligned with different outer side surfaces 130, the atomizer 100 forms different mounting positions relative to the power module 200, and because the insertion portion 120 has four outer side surfaces 130, the atomizer 100 can form four mounting positions relative to the power module 200 in total. In other embodiments, when the cross-section of the receiving cavity 220 is a regular hexagon, the nebulizer 100 may form six mounting positions with respect to the power module 200, and when the cross-section of the receiving cavity 220 is a circle, the mounting positions of the nebulizer 100 with respect to the power module 200 may be three, four, five, or more. When the installation position of the atomizer 100 needs to be changed, the atomizer 100 can be directly pulled out of the accommodating cavity 220, then the atomizer 100 is rotated by a certain angle relative to the power supply assembly 200 outside the accommodating cavity 220, and then the atomizer 100 is inserted into the accommodating cavity 220, so that another different outer side surface 130 can be arranged opposite to the air inlet hole 211, and finally the installation position of the atomizer 100 is changed.

Referring to fig. 2, 4 and 6, for the four outer side surfaces 130 of the insertion part 120, a groove 130a is concavely formed on each outer side surface 130, and the groove 130a extends in a vertical direction. At this time, four grooves 130a are formed on the insertion portion 120, and the four grooves 130a are provided at intervals in the circumferential direction of the nebulizer 100. For convenience of description, the four grooves 130a are respectively denoted as a first groove 131, a second groove 132, a third groove 133 and a fourth groove 134, and the depression depths of the four

grooves

131, 132, 133 and 134 are increased, that is, the cross-sectional dimensions of the four

grooves

131, 132, 133 and 134 are increased, and obviously, the cross-sectional dimensions of the four grooves 130a are different from each other. When the first grooves 131 face the air intake holes 211 to communicate with each other, the atomizer 100 is in a first installation position; when the second grooves 132 face the air intake holes 211 to communicate with each other, the atomizer 100 is in the second installation position; when the third grooves 133 are communicated with each other just opposite to the air intake holes 211, the atomizer 100 is in a third installation position; when the fourth grooves 134 are in communication with each other facing the air intake holes 211, the atomizer 100 is in the fourth installation position. In other embodiments, the groove 130a is not recessed on the lateral side 130 of the insertion portion 120, and the groove 130a is recessed from the medial side 212 of the housing 210.

When the inserting portion 120 is matched with the accommodating cavity 220, a certain resisting pressure is formed between the non-recessed portions of the four outer side surfaces 130 and the inner side surface 212 of the housing 210, so that the inserting portion 120 and the accommodating cavity 220 form a close fit relationship, and the mounting stability and reliability of the atomizer 100 are improved. Meanwhile, the inner side surface 212 of the housing 210 closes the openings of the four grooves 130a, so that the four grooves 130a form four passages 130c having different cross-sectional dimensions a. In fact, the four channels 130c can be considered as part of the receiving cavity 220. Moreover, one of the channels 130c may form an air guide channel 130b, and since the insertion part 120 and the accommodation cavity 220 form a close fit relationship, the four grooves 130a may form a mutual isolation relationship that is not communicated with each other, and then the air guide channel 130b and the other channels 130c may be separated from each other without being communicated with each other.

Referring to fig. 3 and 4, since the buffer channel 243b is directly communicated with the air suction channel 101, and the insertion part 120 and the accommodating cavity 220 form a close fit relationship, when the atomizer 100 is located at the first installation position, the buffer channel 243b is communicated with the first groove 131 through the notch 243a, and the buffer channel 243b cannot be communicated with the second groove 132, the third groove 133 and the fourth groove 134 to be isolated from each other, at this time, the first groove 131 forms an air guide channel 130b, and the external air sequentially enters the air suction channel 101 through the air inlet hole 211, the first groove 131 and the buffer channel 243 b. When the atomizer 100 is at the second installation position, the buffer channel 243b is communicated with the second groove 132 through the notch 243a, and the buffer channel 243b cannot be communicated with the first groove 131, the third groove 133 and the fourth groove 134 to be isolated from each other, at this time, the second groove 132 forms the air guide channel 130b, and the external air enters the air suction channel 101 through the air inlet hole 211, the second groove 132 and the buffer channel 243b in sequence. When the atomizer 100 is at the third installation position, the buffer channel 243b is communicated with the third groove 133 through the notch 243a, and the buffer channel 243b cannot be communicated with the first groove 131, the second groove 132 and the fourth groove 134 to be isolated from each other, at this time, the third groove 133 forms the air guide channel 130b, and the external air enters the air suction channel 101 through the air inlet hole 211, the third groove 133 and the buffer channel 243b in sequence. When the atomizer 100 is located at the fourth installation position, the buffer channel 243b is communicated with the fourth groove 134 through the notch 243a of the buffer channel 243b, and the buffer channel 243b cannot be communicated with the first groove 131, the second groove 132 and the third groove 133 to be isolated from each other, at this time, the fourth groove 134 forms an air guide channel 130b, and the external air enters the air suction channel 101 through the air inlet hole 211, the fourth groove 134 and the buffer channel 243b in sequence. Therefore, the air inlet hole 211, the air guide passage 130b, the buffer passage 243b, and the suction passage 101 together form the entire air flow passage through which air flows. Since the cross-sectional sizes of the air suction channel 101, the buffer channel 243b and the air inlet hole 211 are constant, the function of adjusting the cross-sectional size of the whole air flow channel can be achieved only by changing the cross-sectional size of the air guide channel 130 b.

When a user desires a greater amount of suction, the nebulizer 100 can be placed in the fourth mounting position or the third mounting position. Specifically, since the cross-sectional dimensions of the third groove 133 and the fourth groove 134 are larger, the flow resistance of the gas in the whole gas flow channel can be reduced, so as to reduce the suction resistance of the whole electronic atomization device 10, and then increase the gas flow rate entering the suction channel 101 in a unit time, so that a user can easily obtain a larger gas amount in a shorter time, and finally ensure that the electronic atomization device 10 is suitable for a larger suction amount. When a user requires a smaller amount of suction, the nebulizer 100 can be placed in the first mounting position or the second mounting position. Specifically, since the cross-sectional dimensions of the first groove 132 and the second groove 132 are smaller, the flow resistance of the gas in the whole gas flow channel can be increased, so as to increase the suction resistance of the whole electronic atomizer 10, and then reduce the gas flow rate entering the suction channel 101 per unit time, so that the user can obtain a relatively small gas amount per unit time, and finally ensure that the electronic atomizer 10 is suitable for a relatively small suction amount.

Therefore, the cross-sectional dimension of the whole airflow channel can be adjusted only by changing the installation position of the atomizer 100, so that the function of changing the suction resistance of the electronic atomization device 10 to adapt to different suction volumes is achieved, and finally, the experience of users on different suction volumes is met. In the above arrangement, the atomizer 100 is pulled out and rotated by a certain angle outside the power supply module 200, and then the atomizer 100 is inserted into the power supply module 200 to change the installation position of the atomizer 100, so that the adjustment of the suction resistance and the suction amount applicability is simpler and more convenient, and obviously, the installation positions are distributed at intervals along the circumferential direction of the atomizer 100. And the existing mounting structures of the atomizer 100 and the power supply module 200 are fully utilized, and other additional adjusting components are not needed, so that the manufacturing cost generated by mounting the additional adjusting components is saved, meanwhile, the mounting space occupied by the adjusting components can be eliminated, the structure of the electronic atomization device 10 is more compact, and the development trend of miniaturization design of the electronic atomization device 10 is met.

Referring to fig. 5, 6 and 7, in some embodiments, the atomizer 100 has an end surface 140 facing the power module 200, the end surface 140 is located on the insertion portion 120, and the buffer passage 243b is defined by the end surface 140, the protruding strips 240 and the mounting surface 230. The suction passage 101 penetrates the end surface 140 to communicate with the buffer passage 243 b. The atomizer 100 further comprises a first electrode and a second electrode, each of which is capable of being brought into an electrically connected relationship with the power module 200 at each mounting location. Specifically, the first electrode is a first annular electrode 151, the second electrode is a second annular electrode 152, both the first annular electrode 151 and the second annular electrode 152 may be annular, the second annular electrode 152 is disposed around the first annular electrode 151, and the first annular electrode 151 and the second annular electrode 152 are disposed at an interval in a radial direction of the first annular electrode 151 with reference to the radial direction, so as to prevent the first annular electrode 151 and the second annular electrode 152 from being connected to each other to cause a short circuit. The surfaces of both the first and second

annular electrodes

151 and 152 may also be flush with the end face 140 of the atomizer 100. Of course, both the first electrode and the second electrode may also adopt a thimble-like structure similar to the first thimble 251 and the second thimble 252, that is, the first annular electrode 151 may be replaced by the first thimble 251, and the second annular electrode 152 may be replaced by the second thimble 252. When the atomizer 100 is located in the accommodating cavity 220, the first thimble 251 abuts against the first annular electrode 151, and the second thimble 252 abuts against the second annular electrode 152, so that the atomizer 100 is electrically connected to the power supply module 200. When the atomizer 100 is located at different mounting positions, the first thimble 251 abuts against different portions of the first annular electrode 151, and the second thimble 252 abuts against different portions of the second annular electrode 152, so that no matter how the atomizer 100 changes its mounting position, the first thimble 251 and the first annular electrode 151 always abut against each other, and the second thimble 252 and the second annular electrode 152 always abut against each other, and finally, stable and reliable electrical connection between the atomizer 100 and the power supply module 200 is achieved.

Referring to fig. 6 and 7, the present invention further provides an atomizer 100, wherein the atomizer 100 includes an insertion portion 120, a suction portion 110, a first annular electrode 151, and a second annular electrode 152. For the detailed structure and connection relationship, please refer to the related description in the electronic atomization device 10, which is not described herein again.
