[0093] As used herein, the terms 'upstream' and 'downstream' describe the relative positions of components, or parts of components, in the electronic atomization device in the direction of the flow of the suction airflow.

[0094] like Figure 1-Figure 4 As shown, the electronic atomization device 100 provided in one embodiment of the present application includes a shell assembly 101. The shell assembly 101 can be composed of multiple components, such as a main shell, a top cover arranged at the top end of the main shell, and a bottom cover arranged at the bottom end of the main shell. The shell assembly 101 can also be formed in one piece.

[0095] A nozzle 102 is provided at the top of the housing assembly 101. The nozzle 102 and the housing assembly 101 may be formed integrally or separately. The nozzle 102 is used for the user to inhale the aerosol generated by atomization.

[0096] The housing assembly 101 is formed with a liquid storage chamber 103 that is used to store the first liquid matrix. The first liquid matrix can be a liquid that comprises a tobacco-containing substance that contains volatile tobacco flavor components, or can be a liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture. Spices can comprise menthol, European mint, spearmint oil, various fruity fragrance components etc., but are not limited to this. Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be a material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but are not limited to this. In addition, the first liquid matrix can comprise an aerosol forming agent such as glycerine and propylene glycol.

[0097] Generally, the volume of the first liquid matrix stored in the liquid storage chamber 103 is between 0.1 ml and 2 ml, such as 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, etc. It can be understood that the volume of the liquid storage chamber 103 is slightly larger than the volume of the first liquid matrix stored. In this way, after the first liquid matrix is ​​stored in the liquid storage chamber 103, it can be divided into two parts, such as Figure 5 As shown, one part is the air part A1 above the liquid surface A, and the other part is the liquid matrix part A2 below the liquid surface A.

[0098] An atomizing assembly 104 is also disposed in the housing assembly 101 , and the atomizing assembly 104 is used to atomize the liquid matrix to generate an aerosol.

[0099] In one example, the atomization assembly 104 includes a liquid delivery unit and a heating element.

[0100] The liquid transfer unit can transfer the liquid matrix in the liquid storage chamber 103 to the heating element. For example, the liquid transfer unit can be a porous material such as cotton fiber, ceramic fiber, glass fiber or porous ceramic, porous glass, etc., but is not limited thereto. The liquid transfer unit can be configured as a tubular structure, a plate structure or other regular or irregular shapes.

[0101] The heating element is used to heat the atomized liquid matrix to generate an aerosol.

The heating element can be heated by supplying an electric current, and transfers heat to the liquid matrix in contact with the heating element to heat the liquid matrix, thereby generating an aerosol.

[0102] It should be noted that the atomizing assembly 104 is not limited to the above-mentioned embodiments. In other examples, the heating element may also be a sensor that can be penetrated by a changing magnetic field and generate heat, or an infrared heater that radiates infrared rays. In another example, an ultrasonic atomizer may be used instead.

[0103] An air flow channel 105 is also provided in the housing assembly 101 to transmit the aerosol generated by the atomization assembly 104 to the mouthpiece 102 for inhalation by the user.

[0104] In one example, the lower end of the air flow channel 105 is connected to the air inlet, which can be provided at the bottom end of the housing assembly 101; the upper end of the air flow channel 105 is connected to the suction nozzle 102, that is, it is connected to the air outlet (the dotted arrow in the figure is the air flow direction in part of the air flow channel 105). The liquid storage chamber 103 is arranged around at least part of the air flow channel 105. The atomization assembly 104 is arranged in the air flow channel 105, or the atomization assembly 104 is configured as a tubular structure, and its internal hollow portion defines a part of the air flow channel 105. A liquid hole is provided on the air flow channel 105 to connect the liquid storage chamber 103 and the atomization assembly 104, so that the liquid matrix in the liquid storage chamber 103 can be transferred to the atomization assembly 104 and atomized.

[0105] A circuit 106 is also provided in the housing assembly 101, and the circuit 106 can control the overall operation of the electronic atomization device 100. In detail, the circuit 106 not only controls the operation of the battery cell 107 and the atomization assembly 104, but also controls the operation of other components in the electronic atomization device 100. In addition, the circuit 106 can determine whether the electronic atomization device 100 can be operated by checking the status of the components of the electronic atomization device 100.

[0106] The circuit 106 includes at least one controller. The controller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. In addition, those skilled in the art will appreciate that the circuit 106 may include another type of hardware.

[0107] The battery cell 107 provides power for operating the electronic atomization device 100. For example, the battery cell 107 can provide power to heat the heating element and can provide power required to operate the circuit 106. In addition, the battery cell 107 can provide power required to operate other components provided in the electronic atomization device 100.

[0108] The battery cell 107 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery cell 107 may be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. The battery cell 107 may be a rechargeable battery or a disposable battery.

[0109] It should be noted that the figure only shows the components related to this embodiment. A person skilled in the art should understand that the electronic atomization device 100 may also include Figure 1-Figure 4 Other common components other than those shown. For example, a puff detector may be provided in the housing assembly 101 to detect the user's puffing action and generate a corresponding electrical signal, that is, to detect whether the electronic atomization device 100 is puffed, so that the circuit 106, such as a controller, controls the operation of the battery cell 107, the heating element, etc. according to the electrical signal, for example, controls the battery cell 107 to provide power to the heating element, so that the heating element heats the atomized liquid matrix. The puff detector may be a common pressure sensor, a pressure difference sensor, an airflow sensor, etc.

[0110] It should also be noted that Figure 1-Figure 4 In the example, the above components are formed in one piece, and the electronic atomization device 100 is a common one-piece device. In other examples, the electronic atomization device includes an atomizer and a power supply assembly detachably connected to the atomizer, the atomizer is usually also called a cigarette cartridge, and the power supply assembly is usually also called a cigarette rod; wherein the circuit 106, the battery cell 107, and the puff detector are in the power supply assembly; the nozzle 102, the liquid storage chamber 103, and the atomization assembly 104 are in the atomizer, which is also feasible.

[0111] Please refer to Figure 1-Figure 4 The liquid storage component 200 provided in one embodiment of the present application includes a housing assembly 201, and the housing assembly 201 is composed of a main body 201a and a top cover 202. The main body 201a is a barrel-shaped structure, and the top cover 202 is arranged on the top of the main body 201a.

[0112] The housing assembly 201 is formed with a liquid storage chamber 202 that is used to store the second liquid matrix. Similar to the first liquid matrix, the second liquid matrix can be a liquid that comprises a tobacco-containing substance that contains volatile tobacco flavor components, or can be a liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture. Spices can comprise menthol, European mint, spearmint oil, various fruity fragrance components etc., but is not limited to this. Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be a material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this. In addition, the second liquid matrix can comprise an aerosol forming agent such as glycerine and propylene glycol.

[0113] It should be noted that the properties of the second liquid matrix and the first liquid matrix may be different or the same. For example, the second liquid matrix and the first liquid matrix have different components, or the second liquid matrix and the first liquid matrix have different concentrations. The second liquid matrix may be part of a certain formula, and the first liquid matrix may be another part of a certain formula.

[0114] The volume of the liquid storage chamber 202 is larger than that of the liquid storage chamber 103. Generally, the volume of the second liquid matrix stored in the liquid storage chamber 202 is between 2ml and 10ml, such as 4ml, 5ml, 6ml, 8ml, etc. It can be understood that the volume of the liquid storage chamber 202 is slightly larger than the volume of the stored second liquid matrix. In this way, after the liquid storage chamber 202 stores the second liquid matrix, it can be divided into two parts, one part is the air part above the liquid surface, and the other part is the liquid matrix part below the liquid surface. This can be referred to Figure 5 To understand.

[0115] The liquid storage component 200 is independent of the electronic atomization device 100.

The inner wall of the receiving cavity 108 is provided with a snap connector 108a, and the outer wall of the housing assembly 201 is provided with a snap connector 201c. The snap connector 108a cooperates with the snap connector 201c to realize the snap connection between the housing assembly 201 and the housing assembly 101. It can be understood that the connection method between the housing assembly 201 and the housing assembly 101 is not limited to the above situation.

[0117] When the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 103 and the liquid storage chamber 202 are arranged in sequence substantially along the width direction of the electronic atomization device 100. The liquid storage chamber 103 is arranged near the right end of the electronic atomization device 100, and the liquid storage chamber 202 is arranged near the left end of the electronic atomization device 100.

[0118] When the shell assembly 201 is connected to the shell assembly 101, the air part above the liquid surface of the liquid storage chamber 103 is connected to the air part above the liquid surface of the liquid storage chamber 202, and the liquid matrix part below the liquid surface of the liquid storage chamber 103 is connected to the liquid matrix part below the liquid surface of the liquid storage chamber 202.

[0119] Specifically, please combine Figure 6-Figure 7 It is understood that the housing assembly 101 further includes a through hole 109 and a through hole 110 arranged at intervals. One end of the through hole 109 is in communication with the liquid matrix portion below the liquid surface of the liquid storage chamber 103, and the other end of the through hole 109 extends to the right end of the inner wall of the receiving chamber 108. The through hole 110 is located above the through hole 109, and one end of the through hole 110 is in communication with the air portion above the liquid surface of the liquid storage chamber 103, and the other end of the through hole 110 extends to the right end of the inner wall of the receiving chamber 108.

[0120] The housing component 201 further includes a through hole 203 and a through hole 204 arranged at intervals. One end of the through hole 203 is in communication with the liquid matrix portion below the liquid surface of the liquid storage chamber 202, and the other end of the through hole 203 protrudes from the outer surface of the right side end of the housing component 201. The through hole 204 is located above the through hole 203, one end of the through hole 204 is in communication with the air portion above the liquid surface of the liquid storage chamber 202, and the other end of the through hole 204 protrudes from the outer surface of the right side end of the housing component 201.

[0121] When the shell component 201 is connected to the shell component 101, at least a portion of the wall defining the through hole 203 extends into the through hole 109, so that the liquid matrix portion below the liquid surface of the liquid storage chamber 103 is connected with the liquid matrix portion below the liquid surface of the liquid storage chamber 202; at least a portion of the wall defining the through hole 204 extends into the through hole 110, so that the air portion above the liquid surface of the liquid storage chamber 103 is connected with the air portion above the liquid surface of the liquid storage chamber 202.

[0122] In this case, the through hole 203 and / or the through hole 109 define a liquid channel (first channel), one end of which is in communication with the liquid matrix portion below the liquid surface of the liquid storage chamber 103, and the other end of which is in communication with the liquid matrix portion below the liquid surface of the liquid storage chamber 202. The through hole 204 and / or the through hole 110 define an air channel (second channel), one end of which is in communication with the air portion above the liquid surface of the liquid storage chamber 103, and the other end of which is in communication with the air portion above the liquid surface of the liquid storage chamber 202. The air pressure of the liquid storage chamber 103 and the liquid storage chamber 202 can be balanced through the air channel, so that the second liquid matrix stored in the liquid storage chamber 202 can flow smoothly to the liquid storage chamber 103 through the liquid channel, and the consumed liquid matrix can be replenished to the liquid storage chamber 103 in time.

[0123] In further implementation, please combine Figure 4It is understood that the through hole 203 is arranged close to the bottom wall of the housing component 201, the bottom wall of the housing component 201 is inclined toward the through hole 203, or the bottom wall of the housing component 201 has an inclined surface 201a1 inclined to the through hole 203. In this way, the liquid matrix in the liquid storage chamber 202 can flow into the liquid storage chamber 103 better, rather than accumulating in the liquid storage chamber 202, thereby avoiding waste of the liquid matrix.

[0124] In further implementation, please combine Figure 8 It is understood that the electronic atomization device 100 also includes a puncturable film member 111 and a film member 112. The film member 111 is disposed in the through hole 109 and is disposed near the other end of the through hole 109 or the receiving cavity 108, and the film member 111 is used to close the through hole 109; the film member 112 is disposed in the through hole 110 and is disposed near the other end of the through hole 110 or the receiving cavity 108, and the film member 112 is used to close the through hole 110.

[0125] The liquid storage component 200 further includes a puncturable film 205 and a film 206. The film 205 is disposed in the through hole 203 and close to the other end of the through hole 203, and is used to close the through hole 203; the film 206 is disposed in the through hole 204 and close to the other end of the through hole 204, and is used to close the through hole 204.

[0126] The film pieces 111, 112, 205 and 206 are all made of flexible materials, such as silicone. The thickness of the film piece needs to be set to consider the sealing of the through hole to prevent the liquid matrix from leaking, and to make it relatively easy for the user to puncture.

[0127] In actual use, the liquid storage component 200 can be connected to the electronic atomization device 100 at any time before the first liquid matrix in the liquid storage chamber 103 is consumed. Before the liquid storage component 200 is connected to the electronic atomization device 100, that is, before the shell component 201 is connected to the shell component 101, the film component 111, the film component 112, the film component 205 and the film component 206 can be pierced by a separate piercing member, and then the shell component 201 is connected to the shell component 101.

[0128] In a preferred implementation, Figure 8As shown, the electronic atomization device 100 also includes a piercing member 113 and a piercing member 114. One end of the piercing member 113 extends into the through hole 109 and is arranged close to the film member 111, and the other end of the piercing member 113 can be fixedly connected to the components in the housing assembly 101; one end of the piercing member 113 is in a needle-like or knife-like structure. One end of the piercing member 114 extends into the through hole 110 and is arranged close to the film member 112, and the other end of the piercing member 114 can be fixedly connected to the components in the housing assembly 101; one end of the piercing member 114 is in a needle-like or knife-like structure. In this way, when the other end of the through hole 203 extends into the through hole 109, the other end of the through hole 203 squeezes the film member 111 to deform it toward one end of the piercing member 113. When it continues to extend, the piercing member 113 can pierce the film member 111 and the film member 205 in sequence; similarly, when the other end of the through hole 204 extends into the through hole 110, the other end of the through hole 204 squeezes the film member 112 to deform it toward one end of the piercing member 114. When it continues to extend, the piercing member 114 can pierce the film member 112 and the film member 206 in sequence.

[0129] In further implementation, please combine Figure 8 It is understood that a first sealing member is provided between the through hole 109 and the through hole 203 to seal the gap between the through hole 109 and the through hole 203; a second sealing member is provided between the through hole 110 and the through hole 204 to seal the gap between the through hole 110 and the through hole 204. Both the first sealing member and the second sealing member are made of a flexible material, such as silicone.

[0130] Specifically, the first seal includes a seal 115 and a seal 207, wherein the seal 115 is arranged on the inner surface of the wall defining the through hole 109, and the seal 207 is arranged on the outer surface of the wall defining the through hole 203. In a preferred embodiment, the seal 115 extends along the circumferential direction of the inner surface of the wall defining the through hole 109, such as a ring-shaped seal; the seal 207 extends along the circumferential direction of the outer surface of the wall defining the through hole 203, such as a ring-shaped seal. When the wall defining the through hole 203 extends into the through hole 109, the seal 207 and the seal 115 squeeze each other to form a good sealing effect. Specifically, the seal 207 is sandwiched between the seal 115 and the outer surface of the wall defining the through hole 203, such as the ring-shaped seal 207 is at least partially accommodated in the ring-shaped seal 115. Similarly, the second seal includes a seal 116 and a seal 208. The seal 116 is arranged on the inner surface of the wall defining the through hole 110, and the seal 208 is arranged on the outer surface of the wall defining the through hole 204. When the wall defining the through hole 204 extends into the through hole 110, the seal 208 and the seal 116 are squeezed against each other to form a good sealing effect.

[0131] It should be noted that the sealing member 207 and the film member 205 can be formed in one piece or in separate pieces. Similarly, the sealing member 208 and the film member 206, the sealing member 115 and the film member 111, and the sealing member 116 and the film member 112 can also be arranged in the same manner.

[0132] It should be noted that the above-mentioned electronic atomization device 100 and liquid storage component 200 are independent of each other. Before the electronic atomization device 100 and the liquid storage component 200 are not connected (that is, before the shell component 201 is not connected to the shell component 101), the electronic atomization device 100 can be used alone and sucked, and the atomization component 104 only atomizes the first liquid matrix. After the electronic atomization device 100 and the liquid storage component 200 are connected (that is, after the shell component 201 is connected to the shell component 101), the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix. The combination of the electronic atomization device 100 and the liquid storage component 200 can also be collectively referred to as an electronic atomization device.

[0133] It should also be noted that there can be multiple liquid storage components 200.

[0134] The following combination Figure 9-Figure 14 , an electronic atomization device provided in another embodiment of the present application is described. Figure 9-Figure 14 In the example, Figure 1-Figure 8 For the same reference numerals, please refer to the aforementioned parts.

[0135] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example, the electronic atomization device cannot be used and inhaled before the housing component 201 is connected to the housing component 101. That is, the electronic atomization device can be used and inhaled only after the housing component 201 is connected to the housing component 101, and the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix.

[0136] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example shown in FIG. 1 , the suction nozzle 102 ′ is disposed on the housing assembly 201 .

[0137] exist Figure 1-Figure 8 In the example, no air flow channel is provided in the housing assembly 201 .

[0138] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14In the example, the airflow channel includes a first airflow channel 105a and a second airflow channel 105b. The first airflow channel 105a is arranged in the housing assembly 101, and the second airflow channel 105b is arranged in the housing assembly 201. When the housing assembly 201 is connected to the housing assembly 101, the first airflow channel 105a is communicated with the second airflow channel 105b to transmit the aerosol generated by the atomization assembly 104. Among them, the liquid storage chamber 103 is arranged around at least part of the first airflow channel 105a, and the liquid storage chamber 202 is arranged around at least part of the second airflow channel 105b. The lower end of the first airflow channel 105a is communicated with the air inlet (for example, it can be arranged on the bottom wall of the housing assembly 101), and the upper end of the first airflow channel 105a is communicated with the lower end of the second airflow channel 105b, for example, the upper end of the first airflow channel 105a can extend into the second airflow channel 105b, and the upper end of the second airflow channel 105b is connected to the nozzle 102', that is, it is communicated with the air outlet.

[0139] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example, when the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 103 and the liquid storage chamber 202 are arranged in sequence approximately along the length direction of the electronic atomization device. The liquid storage chamber 103 is arranged near the bottom end of the electronic atomization device, and the liquid storage chamber 202 is arranged near the top end of the electronic atomization device.

[0140] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example, one end of the through hole 109 is connected to the liquid matrix part under the liquid surface of the liquid storage chamber 103, and the other end of the through hole 109 protrudes from the top wall of the shell assembly 101; one end of the through hole 110 is connected to the air part above the liquid surface of the liquid storage chamber 103, and the other end of the through hole 110 protrudes from the top wall of the shell assembly 101.

[0141] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example, one end of the through hole 203 is connected to the liquid matrix portion below the liquid surface of the liquid storage chamber 202, and the other end of the through hole 203 protrudes from the bottom wall of the housing assembly 201. One end of the through hole 204 passes through the liquid storage chamber 202 and is connected to the air portion above the liquid surface of the liquid storage chamber 202, and the other end of the through hole 204 extends to the bottom wall of the housing assembly 201.

[0142] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14In the example, when the shell component 201 is connected to the shell component 101, the other end of the through hole 203 extends into the through hole 109, so that the liquid matrix part under the liquid surface of the liquid storage chamber 103 is connected with the liquid matrix part under the liquid surface of the liquid storage chamber 202; the other end of the through hole 110 extends into the through hole 204, so that the air part on the liquid surface of the liquid storage chamber 103 is connected with the air part on the liquid surface of the liquid storage chamber 202.

[0143] and Figure 1-Figure 8 The difference in the example is that Figure 9-Figure 14 In the example, the number of through holes 110 and through holes 204 are both two and they are spaced apart along the thickness direction of the electronic atomization device. Through multiple air channels, the air pressure of the liquid storage chamber 103 and the liquid storage chamber 202 can be better balanced.

[0144] and Figure 1-Figure 8 Similarly, the housing assembly 101 is further provided with a receiving cavity 108 for receiving part of the housing assembly 201. It is understandable that in other examples, the housing assembly 201 is provided with a receiving cavity for receiving or accommodating at least part of the housing assembly 101, which is also feasible.

[0145] It should be noted that in Figure 1-Figure 8 The other features shown in the examples also apply to Figure 9-Figure 14 For example, Figure 1-Figure 8 Examples include membranes, piercing elements, sealing elements, etc.

[0146] The following combination Fig.15 , an electronic atomization device provided in another embodiment of the present application is described. Fig.15 In the example, Figure 1-Figure 8 For the same reference numerals, please refer to the aforementioned parts.

[0147] and Figure 1-Figure 8 The difference in the example is that Fig.15 In the example of FIG. 1 , when the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 202 is arranged around at least a portion of the liquid storage chamber 103. One end of the air channel C is communicated with the air portion above the liquid surface of the liquid storage chamber 103, and the other end of the air channel C is communicated with the air portion above the liquid surface of the liquid storage chamber 202. One end of the liquid channel D is communicated with the liquid matrix portion below the liquid surface of the liquid storage chamber 103, and the other end of the liquid channel D is communicated with the liquid matrix portion below the liquid surface of the liquid storage chamber 202.

[0148] The following combination Figure 16-Figure 19 , an electronic atomization device provided in another embodiment of the present application is described. Figure 16-Figure 19 In the example, Figure 1-Figure 8 For the same reference numerals, please refer to the aforementioned parts.

[0149] and Figure 1-Figure 8 The difference in the example is that Figure 16-Figure 19 In the example, the housing assembly 101 of the electronic atomization device is provided with a liquid storage chamber 103, an atomization assembly 104 and an air flow channel 105. The air flow channel 105 transmits the aerosol generated by the atomization assembly 104 to the mouthpiece (the upper end of the housing assembly 101) so that it can be inhaled by the user. However, components such as the circuit, the battery cell and the puff detector are not provided in the housing assembly 101. Therefore, Figure 16-Figure 19 The electronic atomization device shown in the figure may also be called an atomizer, a cigarette cartridge, etc. Figure 16-Figure 19 The electronic atomization device shown is used in combination with a power supply assembly (or a cigarette rod), wherein the power supply assembly (or the cigarette rod) is provided with components such as a circuit, a battery cell, and a puff detector.

[0150] and Figure 1-Figure 8 The difference in the example is that Figure 16-Figure 19 In the example, a connecting member 300 is further included, one end of the connecting member 300 is detachably connected to the shell component 101, and the other end of the connecting member 300 is detachably connected to the shell component 201; when the connecting member 300 is connected to the shell component 101 and the shell component 201, the liquid storage chamber 103 can be connected to the liquid storage chamber 202.

[0151] Specifically, the connector 300 can be configured as a tubular structure, and its two ends can be needle-shaped or knife-shaped structures. The length of the connector 300 is not limited, and it can be appropriately made longer. One end of the connector 300 can extend into the through hole 109, thereby communicating with the through hole 109, that is, communicating with the liquid matrix part under the liquid surface of the liquid storage chamber 103; the other end of the connector 300 can extend into the through hole 203, thereby communicating with the through hole 203, that is, communicating with the liquid matrix part under the liquid surface of the liquid storage chamber 202. The hollow portion inside the connector 300 also defines a partial liquid channel (first channel).

[0152] It is understandable that, in other examples, it is also feasible that one end of the through hole 109 extends into the connector 300 (i.e., one end of the connector 300 is arranged around at least part of the through hole 109), and one end of the through hole 203 extends into the connector 300 (i.e., the other end of the connector 300 is arranged around at least part of the through hole 203).

[0153] It should be noted that in Figure 16-Figure 19 In the example of FIG. 1 , only through hole 109 and through hole 203 are provided. In other examples, Figure 1-Figure 8 Similarly, through hole 110 and through hole 204 may also be provided.

[0154] and Figure 1-Figure 8 Similar examples, in Figure 16-Figure 19In the example of , a seal 207 and a film 205, a seal 115 and a film 111 are also provided. When in use, the film 205 and the film 111 can be pierced by the connector 300, and a seal is formed between the seal 207 (or the seal 115) and the connector 300.

[0155] and Figure 1-Figure 8 The difference in the example is that Figure 16-Figure 19 In the example, a stopper 209 is also included. The stopper 209 is arranged in the housing assembly 201. The stopper 209 can be a baffle arranged in the housing assembly 201. In this way, when the other end of the connector 300 extends into the through hole 203, the stopper 209 can limit the other end of the connector 300, which can prevent the connector 300 from being completely inserted into the housing assembly 201 on the one hand, and can also enable the user to confirm that the connector 300 is inserted into the housing assembly 201 on the other hand. It can be understood that the stopper can also be arranged in the housing assembly 101, or in both the housing assembly 101 and the housing assembly 201.

[0156] It should be noted that Figure 16-Figure 19 The connector 300 and its associated features in the example are also applicable to Figure 1-Figure 8 For example, or Figure 9-Figure 14 .

[0157] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments are not used as additional limitations on the content of the present application.
