[0037] An embodiment of the present application provides an atomizer 100, such as Figure 1-Figure 4As shown, the atomizer 100 includes a mouthpiece 10, a liquid storage portion 20 and an electrode holder 30. The liquid storage portion 20 has a first end and a second end that are arranged opposite to each other along its length direction. The mouthpiece 10 is connected to the first end, and the electrode holder 30 is connected to the second end. The electrode holder 30 is connected to an adapted power supply mechanism to provide electric energy to the atomizer 100. After obtaining electric energy, the atomizer 100 can atomize the liquid matrix stored therein to generate an aerosol. The mouthpiece 10 is provided with an air outlet 11 for the aerosol to escape from the atomizer 100. The user can inhale the aerosol by inhaling at the air outlet 11.

[0038] The liquid storage portion 20 is hollow to form a liquid storage cavity 21, and the liquid storage cavity 21 is used to store a liquid matrix that can be atomized. When the liquid matrix stored in the liquid storage cavity 21 is a medicinal solution, the atomizer 100 can be used as a medical atomizer for treating respiratory diseases; and when the liquid storage cavity 21 stores electronic cigarette atomizing liquid, the atomizer 100 can be used as an electronic cigarette.

[0039] The liquid storage part 20 is provided with a holding space 22, and the holding space 22 holds an atomizing assembly 23, and the atomizing assembly 23 can be fixed in the holding space 22 by means of interference fit with the holding space 22. The atomizing assembly 23 includes a liquid guiding element 231 made of porous ceramics, and the liquid guiding element 231 has a liquid absorbing surface 2311 and an atomizing surface 2312 which are arranged opposite to each other in the longitudinal direction, the liquid absorbing surface 2311 faces the liquid storage cavity 21 to receive the liquid matrix, and the atomizing surface 2312 is combined with a heating element 232, and the liquid guiding element 231 can transfer the liquid matrix from the liquid absorbing surface 2311 to the atomizing surface 2312 through the internal microporous structure, and then the heating element 231 on the atomizing surface 2312 can heat the liquid matrix to atomize it and generate an aerosol.

[0040] The heating element 232 can be combined with the liquid-conducting element 231 by printing, deposition, sintering or physical assembly, or wound on the liquid-conducting element 231. The heating element 232 is preferably formed on the atomizing surface 2312 by mixing conductive raw material powder with a printing aid into a slurry, printing it according to a suitable pattern and then sintering it, so that all or most of its surface is tightly combined with the atomizing surface 2312, with high atomization efficiency, less heat loss, and anti-dry burning or greatly reducing dry burning. Suitable materials for the heating element 232 can be nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy or titanium.

[0041] The heating element 232 may be a Figure 5In the square wave shape shown in, or in some other embodiments, the heating element 232 can also be a heating net, a disc-shaped heating element formed by a heating wire spiral, a heating film, and other shapes. In addition, a third sealing member 28 is also provided between the atomizing assembly 23 and the inner wall of the holding space 22. The third sealing member 28 elastically abuts between the atomizing assembly 23 and the inner wall of the holding space 22, thereby sealing the assembly gap between the inner wall of the holding space 22 and the atomizing assembly 23, and preventing the liquid matrix in the liquid storage chamber 21 from leaking through the assembly gap. The third sealing member 28 can be any one of silicone, rubber, or latex.

[0042] The electrode holder 30 is provided with an electrical connection portion of the atomizer 100 , and the electrical connection portion is used to connect to an external power supply component, so as to conduct the electrical energy of the external power supply component to the atomization component 23 .

[0043] Specifically, Figure 3 As shown, the electrode holder 30 includes a central electrode 32, which is disposed inside the electrode holder 30 as a first electrical connection portion. The housing portion of the electrode holder 30 is made of a conductive material, and the conductive housing is formed with a threaded electrode 33, which is disposed on the outer surface of the electrode holder 30 as a second electrical connection portion. The central electrode 32 and the threaded electrode 33 are used to electrically connect to an external power supply component. Figure 5 As shown, the atomizer assembly 23 also includes two conductive leads 233, one of which is electrically connected to the positive electrode of the atomizer assembly 23, and the other is electrically connected to the negative electrode of the atomizer assembly 23. The two conductive leads 233 are electrically connected to the center electrode 32 and the threaded electrode 33 respectively, so that electrical energy can be transmitted to the atomizer assembly 23 through the conductive leads 233, and the heating element 232 on the atomizer assembly 23 can heat the liquid matrix to generate an aerosol.

[0044] like Figure 2 As shown, the electrode holder 30 is also provided with an air inlet 31 for external air to enter the atomizer 100. When the user inhales at the air outlet 11, the external air enters the atomizer 100 through the air inlet 31, and carries the aerosol generated by heating and atomizing the atomizer 100 through the air flow channel inside the atomizer 100 to the air outlet 11, and the user can inhale the aerosol at the air outlet 11.

[0045] In this embodiment, the heating element 232 in the atomizer assembly 23 and the electrical connection portion on the electrode holder 30 are connected by the wire lead 233, and there is no need to use the rigid electrode column used in the prior art to conduct electrical energy to the atomizer assembly 23, thereby saving the cost of the electrode column itself on the one hand, and saving the cost of the bracket used to fix the electrode column on the other hand, thereby reducing the manufacturing cost of the atomizer 100. In addition, in this embodiment, by keeping the atomizer assembly 23 in the holding space 22 of the liquid storage part 20, there is no need to rely on the electrode column to provide support for the atomizer assembly 23.

[0046] In some embodiments, Figure 3 and Figure 6 As shown, the atomizer 100 further includes a first seal 24, which is arranged opposite to the atomizing surface 2312, so that the first seal 23 and the atomizing surface 2312 define an atomizing chamber 2313, and the aerosol escaping from the atomizing surface 2312 is released therein. An air inlet channel is formed between the air inlet 31 and the atomizing chamber 2313, and external air can enter the atomizing chamber 2313 through the air inlet channel. The first seal 24 seals the air inlet channel to prevent external air from flowing to other places. Similarly, the first seal 24 can be any one of silicone, rubber or latex.

[0047] Further in some embodiments, Figure 3 and Figure 6 As shown, a through hole 241 is formed on the first sealing member 24 , and the conductive lead 233 passes through the through hole 241 and is electrically connected to the center electrode 32 and the threaded electrode 33 .

[0048] And, in some embodiments, as Figure 4 As shown, the liquid storage portion 20 also includes a spacing beam 26 that separates the liquid storage chamber 21 and the atomization chamber 2313, and the retaining space 22 is arranged on the side of the spacing beam 26 close to the liquid storage chamber 21, so that when the atomization component 23 is retained in the retaining space 22, the spacing beam 26 can provide support for the atomization component 23, and there is no need to set a support member in the atomization chamber 2313 to support the atomization component 23.

[0049] In addition, it is worth mentioning that when the atomizer assembly 23 is held in the holding space 22 , the liquid suction surface 2311 faces the liquid storage chamber 21 and is completely exposed to the liquid storage chamber 21 , thereby increasing the receiving area of ​​the liquid suction surface 2311 .

[0050] Further in some embodiments, Figure 4 As shown, the inner surface of the holding space 22 is provided with a capillary groove 221. When the atomizer assembly 23 is assembled into the holding space 22, the capillary groove 221 and the surface of the atomizer assembly 23 define an air channel. Figure 4The airflow path indicated by the arrow R4 is used to guide the external air into the liquid storage chamber 21 to relieve the negative pressure in the liquid storage chamber 21 caused by suction, so that the liquid matrix in the liquid storage chamber 21 can continue to flow smoothly to the atomization assembly 23.

[0051] Alternatively, in some embodiments, a capillary groove may be provided on the surface of the liquid guide member 231 of the atomizing assembly 23 , and the air channel is defined by the inner wall of the holding space 22 and the capillary groove on the liquid guide member 231 .

[0052] And, in some embodiments, please continue to see Figure 3 and Figure 6 A receiving groove 242 is also formed on the first sealing member 24. When external cold air enters the atomization chamber 2313, it will mix with the high-temperature aerosol in the atomization chamber 2313 to form condensate. The condensate will drip into the receiving groove 242. The receiving groove 242 collects the dripping condensate to prevent the condensate from dripping and leaking out of the atomizer 100.

[0053] Further in some embodiments, Figure 3 and Figure 6 As shown, the first sealing member 24 is also formed with an air vent 243 as a part of the air inlet passage, the air vent 243 extends to the atomization chamber 2313 and is then communicated with the atomization chamber 2313, and external air enters the atomization chamber 2313 through the air vent 243, and the air vent 243 deviates from the central area of ​​the atomization chamber 2313, thereby preventing external air from directly impacting the central area of ​​the atomization surface 2313 when entering the atomization chamber 2313, which is beneficial to improving the taste of aerosol inhalation.

[0054] In some embodiments, Figure 3 and Figure 4 As shown, the liquid storage part 20 also includes a liquid injection port 211 for injecting a liquid matrix into the liquid storage chamber 21, and the atomizer 100 includes a second sealing member 25 for sealing the liquid injection port 211. Before the atomizer 100 is sold, the manufacturer or distributor of the atomizer 100 can inject the liquid matrix into the liquid storage chamber 21 through the liquid injection port 211, and then seal the liquid injection port 211 with the second sealing member 25, and finally install the nozzle on the liquid storage part 20, which is convenient for assembly, and does not require additional riveting equipment or clamps for assembly. Similarly, the second sealing member 25 can be any one of silicone, rubber or latex.

[0055] Please continue reading Figure 3, an air outlet channel is formed between the air outlet 11 and the atomizing chamber 2313, and the aerosol released in the atomizing chamber 2313 can be transmitted to the air outlet through the air outlet channel, and the air outlet channel includes a first part R2 and a second part R3 which are connected in sequence, one end of the first part R2 is connected to the atomizing chamber 2313, and the other end is connected from the second part R3, one end of the second part R3 is connected to the air outlet 11, and an air inlet channel R1 is formed between the air inlet 31 and the atomizing chamber 2313. Furthermore, according to the above content, when the user inhales at the air outlet 11, the external air first enters the atomizing chamber 2313 through the air inlet channel R1, and then carries the aerosol in the atomizing chamber 2313 through the first part R2 and the second part R3 of the air outlet channel to the air outlet 11, thereby forming a complete airflow channel of the atomizer 100.

[0056] In some embodiments, Figure 3 and Figure 4 As shown, the second portion R3 is defined by the suction nozzle 10 and the second sealing member 25 , and the first portion R2 is defined by the liquid storage portion 20 .

[0057] Specifically, Figure 4 As shown, the liquid storage portion 20 includes a longitudinally extending partition wall 27, which is combined with the inner wall of the liquid storage portion 20, and the partition wall 27 and the inner wall of the liquid storage portion 20 enclose a first portion R2, and the liquid storage cavity 21 and the first portion R2 are respectively located on both sides of the partition wall 27.

[0058] And, in some embodiments, as Figure 3 As shown, the second portion R3 extends in an arc shape. Since the first portion R2 is formed by the partition wall 27 and the inner wall of the liquid storage portion 20, the first portion R2 deviates from the axis of the atomizer 100. Usually, the gas outlet 11 is located on the axis of the atomizer 100. Therefore, the second portion R3 is arranged in an arc shape to connect the gas outlet 11 and the first portion R2, so that the aerosol can be quickly transmitted to the gas outlet 11 after escaping from the first portion R2.

[0059] An embodiment of the present application also provides an electronic atomization device, such as Figure 7As shown, the electronic atomization device includes the atomizer 100 described in the above embodiment and a power supply mechanism 200 electrically connected to the atomizer 100, the power supply mechanism 200 is formed with a chamber 250, the electrode holder 30 of the atomizer 100 can be accommodated in the chamber 250 to be electrically connected to the power supply mechanism 200, and the power supply mechanism 200 is provided with a battery cell 230, a main board 220 electrically connected to the battery cell 230, an airflow sensor 240 electrically connected to the main board 220, and a first electrical connection terminal 210a and a second electrical connection terminal 210a electrically connected to the main board 220. Terminal 210b, the first electrical connection terminal 210a is an internal thread formed on the inner wall of the chamber 250, and the internal thread is threadedly electrically connected to the threaded electrode 33 of the atomizer 100, and the second electrical connection terminal 210b extends axially into the chamber 250, and is used to be inserted into the central electrode 32 of the atomizer 100 to maintain electrical connection, so that the atomizer 100 can be provided with electrical energy through the first electrical connection terminal 210a and the second electrical connection terminal 210b. After obtaining the electrical energy, the atomizer 100 can heat the liquid matrix to generate an aerosol that can be inhaled.

[0060] In addition, the power supply mechanism 200 also has an air inlet hole (not shown) for external air to enter the electronic atomization device. When the user uses the electronic atomization device to inhale, negative pressure is generated inside the electronic atomization device. The airflow sensor 240 senses the internal air pressure and generates a sensing signal. The sensing signal is sent to the controller on the main board 220. The controller controls the battery cell 230 to provide electrical energy to the atomizer 100. After obtaining the electrical energy, the atomizer 100 begins to heat and atomize the liquid matrix to generate an aerosol. At the same time, the external air flows from the power supply mechanism 200 to the atomizer 100, and carries the aerosol generated by the atomizer 100 out of the electronic atomization device, and the user can inhale the escaped aerosol.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
