[0123] according to Figures 1 to 9 As shown in , the device body 100 also includes:

[0124] The connector 151 at least partially penetrates or extends from the device body 100 to the holding space 150; the connector 151 is arranged to be connected to the liquid source 200 to establish fluid communication between the liquid source 200 and the first liquid storage chamber and / or the liquid holding element 23 of the device body 100, so that the liquid source 200 replenishes the liquid matrix to the device body 100. The connector 151 is basically configured to be a hollow tubular shape. A sealing ring 152 is arranged on the connector 151, and then after the connector 151 is inserted into the liquid source 200, a seal is provided between them.

[0125] according to Figures 1 to 9 As shown in the figure, the first tubular element 21 has a connecting portion 28 extending toward the second side 140; one end of the connector 151 surrounds and is coupled to the connecting portion 28, so that the connector 151 is connected and fixed to the first tubular element 21 through the connecting portion 28 and communicates with the first liquid storage chamber and / or the liquid retaining element 23. After assembly, at least a portion of the connector 151 is exposed in the retaining space 150, and the connector 151 has a port 153 exposed in the retaining space 150.

[0129] In some embodiments, the first capillary element 154 includes or is made of flexible fibers such as cotton fibers, non-woven fabrics or sponges, etc. In use, when the liquid matrix of the liquid source 200 flows to the first liquid storage chamber and / or the liquid retaining element 23 via the connector 151, the first capillary element 154 can absorb and buffer the liquid matrix through capillary action to adjust the flow rate of the liquid matrix from the liquid source 200 to the first liquid storage chamber and / or the liquid retaining element 23, which can prevent the liquid matrix from flowing too fast to cause leakage, and release the liquid matrix to ensure the supply rate when the liquid matrix flows slowly. Furthermore, due to the air pressure difference between the first liquid storage chamber and the second liquid storage chamber 214 of the liquid source 200 during suction, the first capillary element 154 replenishes the air in the first liquid storage chamber to the second liquid storage chamber 214 of the liquid source 200 during the suction process of the device body 100 or after the suction is completed. The air passes through the micropores of the first capillary element 154 to generate bubbles in the liquid source 200, thereby facilitating the liquid matrix in the second liquid storage chamber 214 of the liquid source 200 to pass from the liquid to the first liquid storage chamber.

[0130] according to Figures 1 to 9 As shown in the figure, in order to facilitate the air in the first liquid storage chamber to pass through the first capillary element 154; a groove or air groove 29 extending in the longitudinal direction is arranged on one side of the liquid holding element 23.

Therefore, when the liquid source 200 is combined with the device body 100, the air in the first liquid storage chamber enters the second liquid storage chamber 214 through the groove or air groove 29 and the micropores in the first capillary element 154. In some embodiments, the upper end of the groove or air groove 29 is connected to the gap between the liquid holding element 23 and the first sealing element 24; and the lower end of the air channel defined by the groove or air groove 29 is connected to the first capillary element 154. Alternatively, the air passage defined by the groove or air slot 29 is arranged to extend between the first capillary element 154 and the gap between the liquid retaining element 23 and the first sealing element 24 in the longitudinal direction of the device body.

[0131] according to Figures 1 to 9 As shown in FIG. , the liquid source 200 comprises:

[0132] An outer body 210 defines a shell or outer surface of the liquid source 200; the outer body 210 is defined by a first shell portion 211 and a second shell portion 212;

[0133] a flexible sealing element 213 at least partially located between the first housing portion 211 and the second housing portion 212 to provide a seal therebetween;

[0134] A second liquid storage chamber 214 for storing a liquid matrix;

[0135] The second shell portion 212 defines an insertion port 220; when the liquid source 200 is combined with the device body 100, the connector 151 is inserted into the insertion port 220, thereby establishing liquid communication between the second liquid storage chamber 214 of the liquid source 200 and the first liquid storage chamber of the device body 100, thereby allowing the liquid matrix in the second liquid storage chamber 214 to replenish or flow to the first liquid storage chamber of the device body 100.

[0136] according to Figures 1 to 9 As shown, the liquid source 200 also includes:

[0137] The liquid transfer mechanism 230 is movably disposed in the liquid source 200 and can move between a first position and a second position. Figure 4 and Figure 6 FIG. 2 shows a schematic diagram of the liquid transfer mechanism 230 in the first position; in the first position, the liquid transfer mechanism 230 prevents the liquid matrix in the second liquid storage chamber 214 from leaving or flowing out. Figure 5 and Figure 7 Schematic diagram of the liquid transfer mechanism 230 in the second position is shown in FIG. 2 ; in the second position, the liquid transfer mechanism 230 allows the liquid matrix in the second liquid storage chamber 214 to leave or flow out.

[0138] Specifically, the liquid transfer mechanism 230 is at least partially located in the insertion port 220 when in the first position. When the liquid source 200 is coupled to the device body 100, the connector 151 can be inserted into the insertion port 220 to actuate the liquid transfer mechanism 230, thereby moving the liquid transfer mechanism 230 from the first position to the second position. Figure 7 As shown by the arrow P1 , the liquid transfer mechanism 230 can move from a first position to a second position along the width direction of the liquid source 200 .

[0139] In use, the user can operate the liquid source 200 on the second side 140 and press the liquid source 200 toward the first side 130 when the plug port 220 is aligned with the connector 151, such as Figure 6 As shown by the middle arrow P2 , the liquid source 200 is then combined with the device body 100 .

[0140] In some variant embodiments, the device body 100 is further provided with structures such as guide rails or slide grooves exposed in the holding space 150. The guide rails or slide grooves may be arranged horizontally, for example; when the liquid source 200 moves from the second side 140 of the device body 100 toward the first side 130 and then combines with the holding space 150, the liquid source 200 provides guidance on the guide rails or slide grooves. In addition, when the liquid source 200 is combined with the device body 100, the liquid source 200 is at least partially embedded or extended into the guide rails or slide grooves to form a snap connection, thereby preventing the liquid source 200 from falling or forming separation during use.

[0141] according to Figures 4 to 7 As shown, the liquid transfer mechanism 230 includes:

[0142] A substantially cylindrical sealing valve 231, with a through hole 232 arranged on the wall of the sealing valve 231;

[0143] The second capillary element 233 is located inside the sealing valve 231 .

[0144] The sealing valve 231 can move from the first position to the second position, and then change from the closed state to the open state; the sealing valve 231 prevents the liquid matrix of the second liquid storage chamber 214 from flowing out in the closed state, and allows the liquid matrix of the second liquid storage chamber 214 to flow out in the open state. Specifically, the sealing valve 231 disconnects the fluid communication between the second capillary element 233 and the second liquid storage chamber 214 in the closed state; the sealing valve 231 conducts the fluid communication between the second capillary element 233 and the second liquid storage chamber 214 in the open state.

[0145] In some embodiments, the second capillary element 233 includes or is made of flexible fibers such as cotton fibers, non-woven fabrics, or sponges.

[0146] When the liquid transfer mechanism 230 is located at the first position, the through hole 232 of the sealing valve 231 does not extend into the second liquid storage chamber 214, the second capillary element 233 and the second liquid storage chamber 214 are liquid-isolated, and the sealing valve 231 closes or seals the second liquid storage chamber 214. When the liquid transfer mechanism 230 moves to the second position, the sealing valve 231 at least partially extends into the second liquid storage chamber 214, and the through hole 232 of the sealing valve 231 is exposed to the second liquid storage chamber 214, so that the liquid matrix in the second liquid storage chamber 214 can flow through the through hole 232 to the second capillary element 233 to be absorbed, as shown in FIG. Figure 5 and Figure 7 As shown by the arrow R31.

[0147] In use, when the liquid matrix in the second liquid storage chamber 214 flows to the device body 100 via the sealing valve 231, the second capillary element 233 can adjust the flow rate of the liquid matrix from the liquid source 200 to the first liquid storage chamber and / or the liquid retaining element 23 by capillary adsorption and buffering of the liquid matrix, so as to prevent the liquid matrix from flowing too fast to cause leakage, and release the liquid matrix to ensure the supply rate when the liquid matrix flows slowly.

[0148] and according to Figure 7 As shown in FIG. 1 , when the liquid source 200 is coupled to the device body 100 , the first capillary element 154 and the second capillary element 233 are in contact; thus, they regulate the flow rate of the liquid medium in the liquid transfer channel established by the connector 151 and the sealing valve 231 .

[0149] In some embodiments, the volume of the first liquid storage chamber in the device body 100 is smaller than the volume of the second liquid storage chamber 214 of the liquid source 200. The amount of liquid matrix that can be absorbed and stored by the first liquid storage chamber is smaller than the amount of liquid matrix that can be absorbed and stored by the second liquid storage chamber 214 of the liquid source 200. For example, in some specific embodiments, the first liquid storage chamber in the device body 100 can absorb and store 0.5 to 3 mL of liquid matrix, more specifically, 2 mL; the second liquid storage chamber 214 of the liquid source 200 can store 5 to 20 mL of liquid matrix, more specifically, 10 mL.

[0162] In some embodiments, the air flow channel of the device body 100a is defined by a plurality of components to define an air flow path for air to pass through the device body 100a and deliver the aerosol to the air outlet 111a. An air inlet is defined by an assembly gap or hole of the housing 10a of the device body 100a to allow external air to enter during inhalation. Fig.13 In the airflow path indicated by the middle arrow R2, the air entering the device body 100a passes through the supporting element 52a and the second sealing element 51a in sequence and then enters the middle hole of the liquid guiding element 30a, and carries the aerosol to be output from the second tubular element 22a and the aerosol output tube 112a to the air outlet 111a. The absorption element 25a is used to absorb the aerosol condensate of the air delivered to the air outlet 111a, or absorb the aerosol condensate falling from the inner surface of the aerosol output tube 112a.

The first capillary element 154a extends from the joint 151a through the elbow 155a to the first liquid storage chamber or the liquid retaining element 23a.

[0168] In some embodiments, the first capillary element 154a may be formed by a part of a capillary material that is bent and passed through the joint 151a and the elbow 155a in sequence. Alternatively, in some other embodiments, the first capillary element 154a may be composed of or defined by two parts of capillary materials; for example, one capillary material passes through a part of the elbow 155a in the width direction, and another capillary material passes through the joint 151a and another part of the elbow 155a in the longitudinal direction, and then the two capillary materials are in contact at the bend of the elbow 155a to form the first capillary element 154a.

[0169] In this embodiment, according to Figures 10 to 13 As shown, the liquid source 200a includes:

[0170] An outer body 210a, comprising a shell or outer surface defining the liquid source 200a; the outer body 210a is defined by a first shell portion 211a and a second shell portion 212a;
