The present application provides a nebulizer 100 for atomizing a liquid matrix to generate an aerosol. As shown in FIGS. 1 to 4 , the nebulizer 100 includes a shell 10 and a base 20. The shell 10 has a first end 11 and a second end 12 that are opposite to each other along its length direction. The first end 11 is formed with a mouthpiece 111 for a user to inhale the aerosol. The second end 12 is open. At least a portion of the base 20 extends into the shell 10 through the opening of the second end 12 to support components in the shell 10.

A liquid storage chamber 13 is formed in the shell 10, and the liquid storage chamber 13 is used to store atomizable liquid matrix. An air guide tube 14 extends longitudinally in the liquid storage chamber 13, and the air guide tube 14 is connected to the mouthpiece 111. The air guide tube 14 is used to transmit the atomized aerosol to the mouthpiece 111 for the user to inhale.

The liquid storage chamber 13 is provided with a first liquid guide member 15 surrounding the inner wall of the shell 10. The first liquid guide member 15 divides the liquid storage chamber 13 into a first part 131 and a second part 132 distributed longitudinally. The first part 131 is hollow and is used to store liquid matrix. The second part 132 is filled with a liquid storage member 16. The first liquid guide member 15 is in contact with the liquid storage member 16, so that the first liquid guide member 15 is used to absorb the liquid matrix in the first part 131 and transfer the liquid matrix to the liquid storage member 16 for storage.

The first liquid-conducting member 15 and the liquid-storing member 16 may include flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or include porous materials with microporous structures, such as porous ceramics, so that the first liquid-conducting member 15 and the liquid-storing member 16 can absorb the liquid matrix and transfer the liquid matrix through the internal voids or microporous structures.

Fig. 5 is an exploded schematic diagram of the atomizing assembly of the atomizer in Fig. 3 at a viewing angle. Fig. 6 is an exploded schematic diagram of the atomizer in Fig. 3 .

As shown in FIGS. 5 and 6 , the liquid storage member 16 is provided with a first through hole 161 which runs longitudinally, and an atomization assembly 17 is provided in the first through hole 161. The atomization assembly 17 includes a second liquid guide member 171 and a heating element 172 which is coupled to the second liquid guide member 171. Specifically, the second liquid guide member 171 is formed with a second through hole 1711 which runs longitudinally, so that the second liquid guide member 171 has an outer surface 1712 and an inner surface 1713. The heating element 172 is coupled to the inner surface 1713. The outer surface 1712 contacts the liquid storage member 16 to absorb the liquid matrix in the liquid storage member 16, and transfer the liquid matrix to the heating element 172 on the inner surface. The heating element 172 heats and atomizes the liquid matrix to generate an aerosol, and releases the aerosol into the second through hole 1711. That is to say, the second through hole 1711 is the atomization chamber 1714 of the atomizer 100.

The second liquid guide member 171 can also be made of flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or made of porous materials with microporous structures, such as porous ceramics, so that the second liquid guide member 171 can absorb the liquid matrix from the liquid storage member 16 and transfer the liquid to the inner surface 1713, and then transfer it to the heating element 172 for heating and atomization. Accordingly, the heating element 172 can be combined with the second liquid guide member 171 by printing, deposition, sintering or physical assembly, or wound on the second liquid guide member 171.

As shown in FIG2 , the base 20 is provided with an air inlet 22 and an electrode hole. The air inlet 22 is used to provide an air flow inlet for external air to enter the atomizer 100. An electrical connection terminal 21 is provided in the electrode hole. The electrical connection terminal 21 is electrically connected to the electrode lead 1721 of the heating element 172. A portion of the electrical connection terminal 21 is exposed to the end surface of the base 20, so that it is electrically connected to the power supply mechanism through the exposed portion, and the power supply mechanism provides electrical energy to the heating element 172.

As shown in Figures 4 and 6, the first liquid guiding member 15 is formed with a third through hole 151, and the air guide tube 14 passes through the third through hole 151 and extends into the first through hole 161. When the user inhales at the mouthpiece 111, negative pressure is generated inside the atomizer 100, and external air enters the atomizer 100 through the air inlet 22, and further flows into the atomization chamber 1714, and then carries the aerosol generated in the atomization chamber 1714 to flow into the air guide tube 14, and finally flows to the mouthpiece 111 through the air guide tube 14 for the user to inhale.

The atomizer 100 provided in this embodiment divides the liquid storage chamber 13 into a first portion 131 and a second portion 132 distributed longitudinally, and then conducts the liquid matrix in the first portion 131 to the liquid storage member 16 in the second portion 132 for storage through the first liquid guide member 15, and then the liquid storage member 16 further transmits the liquid matrix to the atomizing assembly 17 for heating and atomization to generate aerosol, so that the liquid matrix in the liquid storage chamber 13 can be Instead of being completely adsorbed on the liquid storage member 16 , the liquid matrix can still exist independently in the first portion 131 in liquid form, thereby effectively improving the space utilization of the liquid storage cavity 13 , so that more liquid matrix can be accommodated in the liquid storage cavity 13 .

As shown in FIG. 4 , in some embodiments, the length dimension of the first liquid guide member 15 in the transverse direction is greater than the length dimension in the longitudinal direction, and the length dimension of the liquid storage member 16 in the longitudinal direction is greater than the length dimension in the transverse direction, so that the thickness of the first liquid guide member 15 is thinner, and the thickness of the liquid storage member 16 is thicker, and the first liquid guide member 15 can quickly transfer the liquid matrix to the liquid storage member 16, and more liquid matrix can be stored in the liquid storage member 16. In addition, in some embodiments, the volume of the first part 131 is greater than the volume of the second part 132, so that more liquid matrix can be stored in the first part 131 to increase the total liquid volume of the liquid storage chamber 13.

As shown in FIG. 3 and FIG. 6 , in some embodiments, a receiving member 30 is further provided in the second portion 132, and the receiving member 30 forms a receiving chamber 31, and the liquid storage member 16 is received in the receiving chamber 31. In some examples, the receiving member 30 is non-transparent, and when the housing 10 is designed to be transparent so that the remaining liquid in the liquid storage chamber 13 can be observed through the housing 10, since the color of the liquid storage member 16 changes due to the infiltration of the liquid matrix, when the liquid storage member 16 is received in the receiving chamber 31, the receiving member 30 can shield the liquid storage member 16, and the liquid storage member 16 can be prevented from being observed through the transparent housing 10, thereby avoiding visual discomfort to the user.

As shown in FIG3 , in some embodiments, the receiving member 30 has a first end and a second end that are arranged opposite to each other in the longitudinal direction, and both the first end and the second end are arranged openly, and the first end supports the first liquid guide member 15, and then the first liquid guide member 15 can conduct the liquid matrix in the first part 131 to the liquid storage member 16 through the opening of the first end 11, and the opening of the second end is used to allow external air to enter the atomization chamber 1714. Although the liquid storage member 16 has a certain liquid locking function, with the long-term use of the atomizer 100, a small amount of liquid matrix will still seep out of the liquid storage member 16, and then leak through the opening of the second end. Therefore, in order to prevent the liquid matrix from leaking in this way, the atomizer 100 is further provided with a sealing member 40, and the sealing member 40 is at least partially located in the receiving chamber 31, and then interference fits with the inner wall of the receiving chamber 31 to seal the receiving chamber 31, and prevent the liquid matrix from leaking out of the receiving chamber 31.

In some further embodiments, the base 20 and the receiving member 30 are fixedly connected, and the liquid storage member 16 is positioned in the receiving member 30, and the atomizing assembly 17 is positioned in the liquid storage member 16, so that the base 20, the receiving member 30, the liquid storage member 16 and the atomizing assembly 17 can be formed into an independent assembly through the fixed connection between the base 20 and the receiving member 30. When assembling, the housing 10 is first inverted, and then the first liquid guide member 15 is installed to The housing 10 is then loaded with the independent component, and finally the base 20 is pressed into the housing 10 to complete the assembly, which effectively improves the assembly efficiency. In addition, the base 20, the receiving member 30, the liquid storage member 16 and the atomizing component 17 are formed into an independent component, which can also facilitate the customers of the atomizer 100 manufacturer to inject the liquid matrix themselves. After the customer has injected the liquid matrix, the independent component can be directly loaded into the housing 10.

FIG. 7 is another exploded schematic diagram of the atomizer in FIG. 3 .

In a preferred embodiment as shown in Figure 7, the base 20 is formed with a longitudinally extending plug-in portion 23, and the sealing member 40 is formed with a first plug-in hole 41 adapted to the plug-in portion 23. The plug-in portion 23 is inserted into the first plug-in hole 41 and is interference fit with the hole wall of the first plug-in hole 41, so that the sealing member 40 forms an interference connection with the base 20, and the sealing member 40 is also interference connected with the inner wall of the receiving member 30, and the base 20 and the receiving member 30 can be fixedly connected through the sealing member 40, so that the base 20, the receiving member 30, the liquid storage member 16 and the atomization assembly 17 form an independent assembly.

In some embodiments, please continue to refer to Figures 3 and 7. The seal 40 is also formed with a second plug hole 42, and the electrical connection terminal 21 is inserted into the second plug hole 42. During assembly, the electrode lead 1721 of the heating element 172 can be bent and assembled into the second plug hole 42, so that the electrode lead 1721 is electrically connected to the electrical connection terminal 21. Compared with bending the electrode lead 1721 and assembling it into the electrode hole of the base 20, since the base 20 is a hard plastic part, it is more convenient to assemble the electrode lead 1721 into the second plug hole 42 of the soft plastic part, which can improve the assembly efficiency.

Further in some embodiments, as shown in Figures 3 and 6, the first through hole 161 of the liquid storage member 16 has an air outlet port and an air inlet port that are relatively arranged. The air outlet port is used to allow the aerosol in the atomization chamber 1714 to escape from the liquid storage member 16, and the air inlet port is used to allow external air to enter the atomization chamber 1714. A tubular body 162 extends between the atomization chamber 1714 and the air outlet port, and the air guide tube 14 partially extends into the tubular body 162, so that the aerosol in the atomization chamber 1714 can flow into the air guide tube 14 through the tubular body 162. By setting the tubular body 162, the liquid matrix in the liquid storage member 16 above the atomization assembly 17 can be prevented from leaking into the atomization chamber 1714, so that the user inhales the liquid matrix when the user inhales, affecting the user's experience.

Furthermore, in some embodiments, as shown in FIG. 6 , an air hole 1621 is provided on the wall of the tubular body 162, and external air can enter the liquid storage component 16 through the air hole 1621, and then flow to the first part 131 of the liquid storage cavity 13 through the gaps or micropores in the liquid storage component 16, thereby effectively alleviating the negative pressure generated in the first part 131, so that the liquid matrix in the first part 131 can flow smoothly into the liquid storage component 16, thereby making the air hole 1621 serve as an air channel to guide external air into the liquid storage cavity 13.

In some embodiments, as shown in FIG. 3 , an outer wall of the air guide tube 14 has an abutment boss 141 extending laterally therefrom. The abutment boss 141 abuts against the first liquid guide member 15 , and the abutment boss 141 applies a certain squeezing force to the first liquid guide member 15 , thereby positioning the first liquid guide member 15 in the liquid storage chamber 13 .

The receiving member 30a is formed with a receiving chamber 31a for receiving the liquid storage member 16a, and the sealing member 40a is interference fit with the inner wall of the receiving chamber 31a to seal the receiving chamber 31a to prevent the liquid matrix seeping out of the liquid storage member 16a from leaking out of the receiving chamber 31a.

In some embodiments, as shown in Figures 8-10, the receiving member 30a is formed with an air-guiding element 32a extending longitudinally toward the liquid storage member 16a, and the sealing member 40a is formed with a through hole 41a for the air-guiding element 32a to pass through. The air-guiding element 32a and the inner wall of the through hole 41a define an air channel, which is used to guide external air into the liquid storage member 16a, and then enter the first part 131a of the liquid storage cavity through the liquid storage member 16a, thereby alleviating the negative pressure in the first part 131a, so that the liquid matrix in the first part 131a can flow smoothly into the liquid storage member 16a.
