In this embodiment, the vent section 5441 and the socket section 5442 are integrally formed. It will be appreciated that in other embodiments, not shown, vent section 5441 and socket section 5442 are two separate pieces that are joined together when in use.

The liquid guide piece 5452 is made of porous materials, the porous materials have air permeability, air can be discharged, when the liquid guide piece 5452 is in an adsorption saturation state, smoke liquid can not be further adsorbed, the smoke liquid in the liquid storage cavity 510 is sealed, and after the heat generating piece 5451 heats the smoke liquid on the liquid guide piece 5452, the liquid guide piece 5452 can adsorb the smoke liquid in the liquid storage cavity 510 again. In this embodiment, the liquid guiding member 5452 is coated outside the heat generating member 5451, and the corresponding liquid inlet 5445 is attached to the inner wall of the sleeve joint section 5442, so that the tobacco liquid in the liquid storage cavity 510 is adsorbed into the atomizing cavity 5444 through the liquid absorbing member 5452 via the liquid inlet 5445. The heat generating member 5451 has two pins, the upper ends of the first electrode 546 and the second electrode 547 are both open, one of the pins is inserted into the opening of the first electrode 546, then the clamping force is applied to the first electrode 546 so that the opening of the first electrode 546 is contracted inward to clamp the pin, and similarly, the other pin is inserted into the opening of the second electrode 547 so that the opening of the second electrode 547 is contracted inward to clamp the other pin.

Referring to fig. 20, 21 and 22, the battery assembly 60 includes a battery case 61, a battery holder 62 accommodated in the battery case 61, a battery 63 mounted on the battery holder 62, and a control board 64 mounted on the battery holder 62.

The battery case 61 has a substantially hollow cylindrical structure with an opening at the upper end, the inner cavity of the battery case 61 forms a housing cavity 611, and the lower end of the cartridge case 51 of the cartridge 50 is removably mounted in the upper end of the housing cavity 611. In the present embodiment, the upper end surface of the battery case 61 is recessed downward along the axial direction of the battery case 61 to form the guide grooves 612, and the lower end surface of the mouthpiece 53 is extended downward along the axial direction of the mouthpiece 53 to form the guide ribs 536 engaged with the guide grooves 612. During the process of loading the cartridge 50 into the receiving cavity 611, the two sides of the guiding rib 536 can slide along the two opposite walls of the guiding groove 612, thereby guiding the installation of the cartridge 50. When the cartridge 50 is mounted in place, the cartridge housing 51 is shielded by the battery case 61 and only the mouthpiece 53 is exposed. In order to facilitate the penetration of the amount of the smoke in the reservoir 510, the mouthpiece 53 is made of a transparent or translucent material, so that the amount of the smoke in the reservoir 510 can be observed through the mouthpiece 53 and the cartridge case 51 in this order. It will be appreciated that in other embodiments, not shown, it is also possible to provide a window in the battery case 61, corresponding to the cartridge housing 51, through which the cartridge housing 51 can be exposed when the cartridge 50 is in place.

The battery holder 62 is accommodated in the accommodating cavity 611 and located below the cartridge 50, and a mounting cavity (not shown) is provided on the battery holder 62, and the battery 63 is mounted in the mounting cavity to fix the battery 63. A first terminal 621 and a second terminal 622 are mounted on the upper end of the battery holder 62, wherein the first terminal 621 is electrically connected to one of the positive and negative electrodes of the battery 63, and the second terminal 622 is electrically connected to the other of the positive and negative electrodes of the battery 63. When the cartridge 50 and the battery assembly 60 are mounted in place, the first terminal 621 contacts and electrically connects to the first electrode 546, the second terminal 622 contacts to the conductive sheet 543, and the second terminal 622 is electrically connected to the second electrode 547 through the conductive sheet 543, so that the battery assembly 60 can electrically drive the heat generating element 5451. In addition, the first magnetic member 623 is mounted on the upper end surface of the battery bracket 62 corresponding to the second electrode 547, and the first magnetic member 623 can be attracted to the second electrode 547, so that the reliability of connection between the cartridge 50 and the battery assembly 60 is increased. In this embodiment, the first magnetic member 623 is a magnet. By providing the conductive sheet 543, the arrangement of the first electrode 546, the second electrode 547, the first terminal 621, and the second terminal 622 is more flexible. In this embodiment, when the cartridge 50 is mounted in place, the sensor 6131 is directly under the second electrode 547, the second terminal 622 cannot pass through the sensor 6131 and then is electrically connected to the battery 63, and the conducting strip 543 is provided, so that the second terminal 622 can be arranged on the other side of the battery holder 62 to avoid the sensor 6131. In order to further increase the reliability of the connection between the cartridge 50 and the battery assembly 60 and to make the best use of the space on the upper end surface of the battery holder 62, a second magnetic member (not shown) is sleeved outside the second terminal 622, and the second magnetic member is magnetically connected with the conducting plate 543. It will be appreciated that in other embodiments, not shown, one of the first and second

magnetic members

623, 623 may be omitted, or alternatively, both the first and second

magnetic members

623, 623 may be omitted, and the e-cigarette may be secured to the cartridge 50 and battery assembly 60 by other means, such as by snapping the cartridge 50 and battery assembly 60 together.

A second connecting column (not shown) is also convexly arranged at the upper end of the battery support 62, the second connecting column corresponds to the sensing notch 5414, and a sensing through groove 624 is formed in the second connecting column along the axial direction of the battery support 62. An induction gap 613 is reserved between the battery support 62 and the battery 63, and the induction gap 613 is communicated with the induction through groove 624. When the cartridge 50 and the battery assembly 60 are mounted in place, the second connecting post is inserted into the sensing notch 5414, and the sensing through groove 624 is communicated with the sensing through hole 5426, so that the sensing gap 613 is communicated with the sensing channel 5161. The second connection post can ensure that the cartridge 50 can only be inserted in a single direction, i.e., the cartridge 50 can only be inserted into the battery assembly 60 with the sensing notch 5414 facing the second connection post. Otherwise, the cartridge 50 cannot be inserted into the battery assembly 60 smoothly under the abutting action of the second connecting column. In this manner, the sensing gap 613 is ensured to communicate with the sensing channel 5161 when the cartridge 50 is installed in place.

The control board 64 is provided with a USB jack 641, the control board 64 is electrically connected to the battery 63, and an opening is provided on the lower end surface of the battery case 61 corresponding to the USB jack 641, so that the USB jack 641 is exposed through the opening, and a user can charge the battery 63 through the USB jack 641. Because the opening is located on the lower end face of the battery shell 61, the opening is hidden, so that the electronic cigarette is attractive. The control board 64 is provided with the charge state indicating circuit according to the first embodiment, and can accurately indicate the charge state of the battery assembly 60 during charging. In addition, the USB jack 641 is connected to the sensing gap 613 and the outside atmosphere. A sensor 6131 is installed in the sensing gap 613, and the sensor 6131 is electrically connected with the control board 64. When a user sucks through the mouthpiece 53, the external air enters the sensing gap 613 through the USB socket 641, flows through the sensor 6131, and then flows out through the sensing through groove 624, the sensing notch 5414, the sensing through hole 5426, the sensing channel 5161, the sensing hole 5241, the sensing groove 528 and the smoke outlet 532 in sequence. The sensing notch 5414, the sensing through hole 5426, the sensing channel 5161, the sensing hole 5241, and the sensing groove 528 together form a sensing channel. In this embodiment, the sensor 6131 is an airflow sensor, when the airflow sensor detects an airflow, a start signal is generated and transmitted to the control board 64, and the control board 64 controls the battery 63 to supply power to the heat generating element 5451 after receiving the start signal. It is understood that in other embodiments, not shown, the sensor 6131 may also be an air pressure sensor, one side of the air pressure sensor is communicated with the outside through the USB socket 641, and maintains a normal pressure, and the other side of the air pressure sensor generates a negative pressure under the suction effect, the air pressure sensor generates an activation signal when a pressure difference is generated between the two sides, the air pressure sensor transmits the activation signal to the control board 64, and the control board 64 can also control the battery 63 to supply power to the heat generating element 5451 after receiving the activation signal. It will be appreciated that in other embodiments, not shown, the sensing gap 613 may be in communication with the outside atmosphere by other means, such as, for example, by providing an opening in the battery case. It will be appreciated that in other embodiments, not shown, to prevent false triggering due to disturbance of the airflow, a threshold value may also be set, and the sensor 6131 may generate the activation signal only when the intensity of the airflow is greater than or equal to the threshold value, or only when the difference in air pressure between the two sides is greater than or equal to the threshold value.

In the present embodiment, it is advantageous for the sensor 6131 to detect the suction of the user to dispose the sensor 6131 below the upper end surface of the battery holder 62, specifically, to dispose the sensor 6131 in a sensor mounting groove (not labeled) opened on the lower surface of the upper end of the battery holder 62, the sensor mounting groove being communicated with the sensing through groove 624, such that the sensor 6131 is close to the sensing through groove 624 and opposite to the sensing through groove 624. For the airflow sensor, since the airflow sensor is far from the USB socket 641, as long as the user does not suck through the mouthpiece 53, after the external atmosphere enters the sensing gap 613 through the USB socket 641 under disturbance, it is difficult to further flow through the airflow sensor through the long sensing gap 613, so that the airflow sensor generates an activation signal, and thus false triggering can be prevented. The passage through which the air pressure sensor communicates with the mouthpiece 53 is shortened in the case of the air pressure sensor, and thus, sealing of the passage is facilitated, so that it is ensured that the air in the passage is drawn out by the user, so that a negative pressure is generated on the side of the air pressure sensor corresponding to the passage. It is understood that the longer the passage, the more difficult it is to ensure the airtightness of the passage, and when the passage is less airtight, it may cause an interfering airflow into the passage, making it difficult for the side of the air pressure sensor corresponding to the passage to generate a negative pressure.

The battery case 61 is provided with a plurality of glue stealing ports 615, so that the weight is reduced, and meanwhile, the materials are saved, in addition, the side wall of the battery case 61 is provided with a decorative plate 614 corresponding to the glue stealing ports 615, and the decorative plate 614 shields the glue stealing ports 615, so that the product is attractive, and meanwhile, the consistency of the product appearance is ensured. In the present embodiment, two decorative plates 614 are provided, and are attached to opposite side surfaces of the battery case 61.

When a user sucks the electronic cigarette through the cigarette holder 53, outside air enters the atomizing cavity 5444 through the air inlet 535, the air inlet 517, the air inlet cavity 513, the air inlet groove 5417, the ventilation gap 5420 and the air inlet gap 5423 in sequence, is mixed with generated smoke, and then flows into the mouth of the user through the smoke outlet channel 5443, the smoke outlet gap 5151, the smoke outlet 522, the through hole 5252, the gap between the protrusions 533, the opening 534, the air guide groove 527, the liquid injection groove 526 and the smoke outlet 532 in sequence. Wherein, the air inlet 535, the air inlet 517, the air inlet chamber 513, the air inlet slot 5417, the ventilation gap 5420 and the air inlet gap 5423 together form an air inlet channel (not shown). It can be seen that the sensing channel is isolated from both the air inlet channel and the smoke outlet channel 5443, so that smoke does not enter the sensing channel, thereby not affecting the sensor 6131. In addition, because the cigarette outlet channel 5443 is arranged inside the liquid storage cavity 510, partial heat of the airflow flowing through the cigarette outlet channel 5443 can be transferred to the cigarette liquid in the liquid storage cavity 510, so that the cigarette liquid has a certain temperature in the atomizing cavity 5444, the atomizing efficiency is improved, the energy consumption is reduced, meanwhile, the temperature of the airflow flowing out through the cigarette outlet 532 is also reduced, and the user is prevented from being scalded. In addition, a sealing ring 625 is interposed between the battery holder 62 and the battery case 61, and the sealing ring 625 can effectively prevent air flow from leaking between the battery holder 62 and the battery case 61, thereby affecting the sensitivity of the sensor 6131. It is understood that the sealing ring 625 is a rubber ring or a silicone ring. In addition, the upper end face of the battery support 62 is matched with the sealing ring 625 to seal the battery support 62, the battery 63 and the control panel 64, so that the danger caused by the fact that children touch the parts is prevented, and the situation that the use of the electronic cigarette is influenced due to the fact that a user modifies a circuit at will is avoided.

Referring to fig. 23, during liquid injection, the cigarette cartridge 50 is turned upside down, the liquid injection needle 70 penetrates through the cigarette holder 53 through the cigarette outlet 532 and then pierces the sealing member 52, so that one end of the liquid injection needle 70 extends into the liquid storage cavity 510 to inject liquid into the liquid storage cavity 510. The upside-down state of the cartridge 50 is a state in which the end of the electronic cigarette having the smoke outlet 532 is positioned downward. In the liquid injection process, air in the liquid storage cavity 510 enters the atomizing cavity 5444 through the liquid inlet 5445 and the liquid guide piece 5452, and is discharged through the air inlet channel or the smoke outlet channel 5443, or is discharged through the air inlet channel and the smoke outlet channel 5443 simultaneously. The reason for invert the cartridge 50 when annotating the liquid lies in, if the cartridge 50 is just putting, then the tobacco juice can flow to the part that stock solution chamber 510 is close to atomizing part 545 earlier under the action of gravity, so, the tobacco juice forms the liquid seal to inlet 5445, leads to the unable smooth discharge of gas in the stock solution chamber 510, and then makes the tobacco juice can't be full of the stock solution chamber, if discharge by force, then the tobacco juice probably leaks under great pressure. In order to prevent the liquid seal of the liquid inlet 5445 by the smoke cartridge 50, the liquid can be injected after the smoke cartridge is horizontally placed. Or, the liquid storage cavity 510 is filled with a liquid storage part made of a porous material, so that the cigarette cartridge 50 can be placed at will during liquid injection, and even if the cigarette cartridge 50 is placed right, liquid seal of the liquid inlet 5445 by the cigarette liquid is difficult to form. This is because the smoke is difficult to flow downward under the force of gravity under the blockage of the liquid storage member, and the smoke is locked in the liquid storage member, so that a liquid seal is not formed for the liquid inlet 5445. When the cigarette liquid atomizing device is used, the cigarette liquid in the liquid storage part can be adsorbed by the atomizing part 545. Only in the process of liquid injection, the gas in the liquid storage chamber 510 can be discharged through the liquid inlet 5445. In addition, the sealing part 523 and the smoke outlet 532 of the sealing element 52 are symmetrically arranged about the axis of the cartridge 50, so that the material arrangement is convenient, and automatic liquid injection is realized. Specifically, after the cigarette cartridge 50 is assembled, only the cigarette cartridge 50 needs to be inverted through material arranging equipment such as a vibrating screen and a vibrating tray, the orientations of the two sides of the cigarette cartridge 50 do not need to be adjusted, the liquid injection needle head 70 can be always aligned to the sealing part 523, and the liquid injection efficiency is improved. The sealing member 52 is a resiliently deformable member that may be made of a soft material having resilient deformability, may be a high-elasticity polymer such as rubber or silicone, or may be made of a free-healing material. Thus, the sealing member 52 can form a seal again after the injection needle 70 is pulled out, thereby closing the liquid storage chamber 510 and preventing the smoke liquid from flowing out. The opening of the injection groove 526 reduces the thickness of the part to be punctured on the sealing element 52, which is beneficial to the puncturing operation of the injection needle head 70. It will be appreciated that in other embodiments, not shown, instead of the priming hole 5152 being provided at the upper end of the cartridge case 51, the priming hole 5152 may be provided at other portions of the cartridge case 51, for example, the side wall of the cartridge case 51 or the lower end of the cartridge case 51, with the sealing member 52 sealing against the priming hole 5152. That is, the positions of the liquid injection hole 5152 and the sealing member 52 are not limited, and it is only necessary to ensure that the smoke liquid can be smoothly injected into the liquid storage chamber 510 and the air in the liquid storage chamber 510 can be smoothly discharged when the liquid is injected.

In the cigarette cartridge 50 provided by the second embodiment of the invention, after the cigarette cartridge 50 is assembled, the liquid injection needle 70 is utilized to pierce the sealing element 52 for liquid injection, after the liquid injection is completed, the liquid injection needle 70 is pulled out, and the sealing element 52 automatically restores to be sealed, so that the liquid injection operation is convenient for users and manufacturers, the automatic liquid injection is convenient for the manufacturers to realize, the process can be realized without disassembling the cigarette cartridge 50, and the operation is simple and the use is convenient.

In addition, referring to fig. 2-1, 2-2 and 2-3, the electronic cigarette is a long strip shape as a whole as seen from the electronic cigarette, and the outer peripheral surface of the electronic cigarette includes a first surface 91 and a second surface 92 which are oppositely arranged, and a third surface 93 and a fourth surface 94 which are oppositely arranged. The first surface 91 and the second surface 92 are symmetrical with respect to the central axis of the e-cigarette, and the third surface 93 and the fourth surface 94 are also symmetrical with respect to the central axis of the e-cigarette. The first surface 91 and the third surface 93 are connected by a fifth surface 95, the first surface 91 and the fourth surface 94 are connected by a sixth surface 96, the second surface 92 and the third surface 93 are connected by a seventh surface 97, and the second surface 92 and the fourth surface 94 are connected by an eighth surface 98. The fifth surface 95, the sixth surface 96, the seventh surface 97, and the eighth surface 98 are all arc surfaces. The top end of the outer peripheral surface of the electronic cigarette is closed by a top surface 910 (the upper end surface of the cartridge 50), and the bottom end of the outer peripheral surface of the electronic cigarette is closed by a bottom surface 920 (the lower end surface of the battery pack 60). The first surface 91 and the second surface 92 are wide surfaces, the width of the first surface 91 and the width of the second surface 92 are 10mm-20mm, the distance between the first surface 91 and the second surface 92 is 5mm-15mm, the design of the wide surfaces and the distance between the first surface 91 and the second surface 92 are narrow, so that a user can easily hold the electronic cigarette, and the user can directly hold the first surface 91 and the second surface 92, so that the electronic cigarette can be smoked. It can be understood that some users prefer to hold the electronic cigarette, when the user holds the electronic cigarette, the thumb of the user can be placed on any one of the fifth surface 95, the sixth surface 96, the seventh surface 97 and the eighth surface 98, and since the fifth surface 95, the sixth surface 96, the seventh surface 97 and the eighth surface 98 are all arc surfaces, the transition between the surfaces is eased, so that the thumb of the user is more comfortable, and the user experience is better. The first surface 91 to the eighth surface 98 of the electronic cigarette are gradually shrunk inward at the end near the top surface 910 to form a suction end (not shown) of the mouthpiece 53, so that the suction end is better experienced by the user when the suction end is placed in the mouth of the user due to the rounded transition and the small thickness. The first surface 91 and the second surface 92 are flat surfaces, and the electronic cigarette can be placed on the table top through one of the first surface 91 and the second surface 92 without any tumbling.

The electronic cigarette according to the second embodiment of the present invention has all the technical features of the cartridge 50, and therefore has the same technical effects as the cartridge 50.

The cartridge 500 differs from the cartridge 50 of the second embodiment in that in this embodiment, the seal 52 attached to the top end of the cartridge case 10 is omitted, and the atomizing member 545 is different in structure.

In this embodiment, only the smoke outlet gap 5151 and the sensing opening 5153 are formed in the top of the shell 51, the smoke outlet gap 5151 is communicated with the smoke outlet 532 and the smoke outlet passage 5443, and the sensing opening 5153 is communicated with the smoke outlet 532 and the sensing passage 5161.

The lower end opening of the cartridge case 51 serves as a liquid injection hole, and the sealing plug 542 constitutes a sealing member for sealing the liquid storage chamber 510, and liquid injection is performed through the sealing plug 542. In this way, the step of opening the cartridge housing 51 can be eliminated, and the seal 52 can be eliminated. Specifically, the bottom wall of the base 541 is provided with a communication opening 548, and the injection needle 70 penetrates through the base 541 through the communication opening 548 to pierce the sealing plug 542, so that the injection needle 70 extends into the liquid storage chamber 510 to inject liquid into the liquid storage chamber 510. The material of the sealing plug 542 is the same as that of the sealing member 52 in the second embodiment, so that the sealing plug 542 can automatically restore the sealing function after the injection needle head 70 is pulled out. During liquid injection, the cartridge 500 also needs to be inverted, and the liquid will fill the end of the liquid storage chamber 510 away from the atomizing member 545 under the action of gravity, so that a liquid seal is not formed. In the present embodiment, since only one communication port 548 is provided and is not provided at the central axis position of the cartridge 500, the communication port 548 does not necessarily face the injection needle 70 after the cartridge 500 is loaded. Therefore, the bottom of the base 541 is provided with the magnetic element 5418, the magnetic element 5418 has magnetism or can be magnetically attracted, after the cartridge 500 is inverted, the material arranging device can make the orientation of the cartridge 500 consistent through the magnetic action, so that the communicating opening 548 on the cartridge 500 after material arrangement is opposite to the liquid injection needle 70. In this embodiment, the magnetic member 5418 is a magnet. It is understood that in other embodiments not shown, the magnetic element 5418 may be omitted, and manual material arrangement may be performed, or, referring to the second embodiment, two communicating ports 548 symmetrically arranged about the central axis of the cartridge 500 may be provided. The sealing plug 542 is provided with a liquid injection groove (not shown), and the thickness of the part of the sealing plug 542 to be penetrated is also reduced to facilitate the penetration of the liquid injection needle 70.

To avoid the communication port 548 communicating with the communication gap 5420 and thereby causing gas to leak through the communication port 548, a vent seal 5428 is mounted within the communication port 548, the vent seal 5428 separating the communication gap 5420 from the communication port 548. It is understood that the material of the vent seal 5428 includes, but is not limited to, silicone or rubber.

In this embodiment, the atomizing member 545 is a ceramic heating member, and the ceramic heating member has both functions of guiding liquid and heating, i.e., the atomizing member 545 is both a liquid guiding member and a heating member. The ceramic heating element comprises porous ceramic and a heating element sintered in the porous ceramic. The lower end of the atomizing member 545 is connected to the sealing plug 542, and the upper end of the atomizing member 545 is connected to the vent pipe 544. The atomizing member 545 is provided with an atomizing chamber 5444 along the axial direction of the atomizing member 545. In the liquid injection process of the cartridge 500, air in the liquid storage chamber 510 enters the atomizing chamber 5444 through the atomizing member 545, and is discharged through the air inlet channel or the smoke outlet channel 5443, or is discharged through the air inlet channel and the smoke outlet channel 5443 at the same time. After the liquid injection is completed, the atomizing member 545 can prevent the smoke liquid from leaking. In addition, a sealing gasket 5446 is installed on the ventilation pipe 544, the lower end of the ventilation pipe 544 is inserted into the upper end of the sealing gasket 5446 in a sealing manner, and the upper end of the atomizing member 545 is inserted into the lower end of the sealing gasket 5446 in a sealing manner, so that the smoke liquid is prevented from leaking through the joint of the ventilation pipe 544 and the atomizing member 545. The material of the sealing pad 5446 includes, but is not limited to, silicone or rubber. Further, the atomizing member 545 in the present embodiment can be applied to example two, and the atomizing member 545 in example two can be applied to the present embodiment. Note that, in the present embodiment, the mouthpiece 53 does not cover the air inlet hole 517, and therefore the mouthpiece 53 is not provided with the corresponding air inlet 535. Because the air inlet hole 517 is disposed near the lower end of the cartridge housing 51, the air inlet hole 517 may be shielded by the battery case 61 when the cartridge 50 is inserted into the battery assembly 60, in one embodiment, the air inlet opening 535 is opened on the battery case 61, and in another embodiment, a flange is disposed on the inner wall of the battery case 61 and/or the outer wall of the cartridge housing 51, so that after the cartridge 50 is inserted into the battery assembly 60, a gap is left between the cartridge housing 51 and the battery case 61, and the gap communicates the air inlet hole 517 with the external atmosphere.

The battery assembly of the third embodiment has the same structure as the battery assembly 60 of the second embodiment, and the description thereof is omitted. It will be appreciated that in other embodiments not shown, the cartridge 500 of the third embodiment may also be coupled to other power supply devices other than the battery assembly 60.

In the second embodiment, the mouthpiece 53 is used as a shielding member, and the smoke outlet 532 is used as a communication port, so that the user can not directly contact the sealing member 52, the sealing member 52 can be prevented from being detached by children, and the adult user can insert the injection needle 70 into the sealing member 52 through the smoke outlet 532 to inject liquid. In the third embodiment, the base 541 is used as a shielding member, and the base 541 is connected to the cartridge housing 51 and is not detachable, so as to prevent children from contacting the sealing plug 542, and arbitrarily detach the sealing plug 542 to contact the smoke liquid. On the other hand, because the shielding member is fixedly connected with the cartridge housing 51, the sealing member (the sealing member 52 in the second embodiment and the sealing plug 542 in the third embodiment) is located between the shielding member and the cartridge housing 51, and the shielding member constitutes a part of the outer contour of the

cartridge

50, 500, therefore, the sealing member is shielded by the shielding member, so that a child cannot randomly contact the sealing member, and the sealing member cannot randomly shake under the clamping action of the shielding member and the cartridge housing 51, and the sealing member is prevented from being driven to cause liquid leakage when the injection needle 70 is pulled out. The essential parts of the

cartridges

50, 500, namely the mouthpiece 51 and the base 541, are used as the shielding piece, so that one part has multiple functions, and the structural arrangement is more reasonable.

In the second embodiment, the filling process using the sealing plug 542 can be performed in the same manner as in the third embodiment. In one embodiment, the sensing notch 5414 is used as a communication port, and the injection needle 70 penetrates into the sealing plug 542 after passing through the sensing notch 5414 and then extends into the liquid storage chamber 510 for injection; in another embodiment, the position of the air inlet hole 517 is changed, the air inlet hole 517 is opened on the base 541, at this time, both the air inlet chamber 513 and the air inlet opening 535 can be omitted, the air inlet hole 517 is communicated with the ventilation gap 5420, the air inlet hole 517 is used as a communication port, during liquid injection, the liquid injection needle 70 penetrates the sealing plug 542 after sequentially passing through the air inlet hole 517 and the ventilation gap 5420, and then, extends into the liquid storage chamber 510 for liquid injection.

In light of the foregoing description of preferred embodiments in accordance with the invention, it is to be understood that numerous changes and modifications may be made by those skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the contents of the specification, and must be determined according to the scope of the claims.
