Description

e-cigarette

The present invention relates to vaporization devices for personal use, such as electronic cigarettes. In particular, the present invention relates to an electronic cigarette which is configured to receive a disposable cartridge containing vaporizable material.

Electronic cigarettes are substitutes for conventional cigarettes. Instead of generating combustion smoke, the electronic cigarette vaporizes the liquid that can be inhaled by the user. Liquids typically include aerosol forming substances, such as glycerin or propylene glycol that generates vapor. Other common substances in liquids are nicotine and many different flavors. There are several different types of e-cigarettes, and generally they can be divided into liquid vaporizers, heated tobacco vaporizers, or combinations thereof (ie, mixing devices).

Electronic cigarettes are typically palm-type inhaler systems, including a mouthpiece part and a power supply part. E-cigarettes are usually configured to receive disposable cartridges containing vaporizable materials, and are further provided with a power supply part and cartridge holders for accommodating the cartridges and for heating the substrate to generate inhalable vapor to be sucked through the mouthpiece .

There are many problems with this known device. One problem is that since a certain number of functional components must be assembled together in the housing, which may be a time-consuming process and requires significant skills, the manufacture and assembly of the device are not simple. Slight changes in the corresponding positioning of the functional components during assembly can also cause performance changes between devices. In addition, the arrangement of known devices cannot provide sufficient protection to prevent accidental damage, such as preventing the device from falling.

Another problem is that in known devices, air often enters the device through multiple openings (eg, charging ports) in the housing during inhalation, in addition to the expected air inlets. This may cause the pressure change due to inhalation to vary from device to device, which may cause problems with reliably configuring the air flu detector to trigger the heater during inhalation.

An object of the present invention is to provide an electronic cigarette that solves some of these problems.

According to a first aspect of the present invention, there is provided an electronic cigarette, the electronic cigarette comprising: an outer casing sleeve having an open end and a closed end, with an air inlet positioned towards the closed end; a functional insert The functional insert includes an electrical component and a cartridge holder arranged to receive a removable cartridge, the electrical components include a power source, wherein the functional insert is arranged to be introduced through the open end of the outer casing sleeve And is held in the outer casing sleeve; an air passage plug, the air passage plug is arranged in the outer casing sleeve, between the closed end of the outer casing sleeve and the functional insert, the air passage plug It includes an air passage arranged to provide at least a part of an air flow path connecting the air inlet to the cartridge holder.

By providing an air channel plug at the closed end in the base of the outer casing sleeve, further protection is provided for the electronic components, making the device more resistant to accidental damage. In addition, the air flow path from the air inlet to the device is better defined because the air passage plug blocks the air from entering the device instead of through the air inlet and air passage, so that the air is correctly delivered to the cartridge holder. This reduces the empty volume of the device, which may result in a lack of responsiveness of the air flu detector. By providing an airflow channel from the air inlet, the pollution of the airflow before reaching the cartridge, such as pollution from other internal components of the device, is further reduced.

The functional insert preferably includes the power source, the cartridge holder, and an electrical connection for connecting the power source to the heater in the cartridge.

The applicant has realized that providing a functional insert for integrating each of the main electrical components including the power supply and the cartridge holder into a single unit achieves many technical advantages. In particular, the assembly process is greatly simplified, because the assembled functional insert can be easily sleeved in the outer casing sleeve, and tolerances are reduced by including an elastic air passage plug that rests against the functional insert The elastic air passage is plugged. In addition, since all major electrical components are integrated into the functional insert, the air channel plug can provide them with greater protection, thereby providing a more robust device.

As a result, significant progress has been made with respect to prior art devices, which use some form of removable inserts during assembly but do not integrate each of these major electrical components into functional inserts Therefore, these prior art devices are still affected by more complicated assembly procedures, and when all the sensitive components are not sheathed together against the air channel plug in the housing, the sensitive components are more susceptible to impact damage.

Therefore, the movement of the lever 72 in the horizontal direction of the electronic cigarette 1 should be reduced. Therefore, the hinge mechanism 70 may be designed to provide a combined rotational movement and linear movement of the nozzle portion 30 when the nozzle portion 30 is moved to the open position.

The hinge mechanism 70 may be configured to enable the suction nozzle portion 30 to both rotate and axially move away from the functional insert 20, which allows the opening 26 of the first cartridge holder 21 to be exposed with a reduced degree of rotation of the suction nozzle portion 30, Therefore, the space required for the hinge mechanism 70 is reduced. In order to achieve the rotational movement and linear movement of the suction nozzle portion 30, a receiving portion 77 in the form of an elongated axial groove 77 is shown in FIG. 2B, in which a rotary joint 76 at the rotating end 76 of the lever 72 is held . The linear groove 77 and the lever 72 are held so that the rotating end of the lever 72 can rotate within the groove 77 and move linearly in a direction corresponding to the long axis of the groove 77. In this way, when the nozzle portion 30 is moved to the open position, the lever 72 can both rotate and translate.

Therefore, the linear groove 77 defines an end position including the limit of linear motion, wherein the end position corresponds to the position of the rotary joint 76 when the suction nozzle portion 30 is in the closed position and the open position, respectively. Therefore, as shown in FIG. 2B, when the nozzle portion is in the closed position, the joint 76 at the rotating end of the lever 72 is located at the lower end of the linear groove, and as shown in FIG. 4, when the nozzle portion 4 is in the open position, the joint 76 is located at the lower end of the linear groove. 76 is located in the upper end of the linear groove 77.

The restricting surface S shown in FIG. 2B may be provided on the axial extension connected to the functional insert 20 and meet the corresponding surface of the lever 72 when reaching the fully open position, thereby restricting further rotation of the lever 72. In other words, the functional insert 20 includes an inner surface S that is arranged to meet the lever when the lever 72 rotates to prevent further rotation at a specific point. The surface S may be provided as a part of the first end 24 of the functional insert, which portion extends along the long axis of the functional insert 20 in the direction toward the suction nozzle 30.

The linear movement of the mouthpiece portion 30 makes it possible to release the opening 26 of the main cartridge holder 21 with the smallest degree of rotation of the mouthpiece portion 30, so that the first cartridge 40 can be introduced. This also reduces the space required for the hinge mechanism 70 in the functional insert 20.

Preferably, one or more holding elements 88 in the form of magnetic elements may be positioned to facilitate the rotational movement and linear movement of the nozzle portion 30 provided by the hinge mechanism 70. In particular, the magnetic element 88b (see FIG. 2B) may be provided on the restricting surface S, and the corresponding magnetic material 88a may be provided on the opposite surface of the lever 72, so that when the user initially opens the mouthpiece portion 4, the lever is promoted 72 rotates and moves linearly upward so that the corresponding magnets meet, and then the suction nozzle portion 30 is maintained in a stable open position.

As shown in FIG. 3, the lever 72 is substantially L-shaped and includes a horizontal portion 73, a vertical portion 75 and a joint 76. The L shape allows a point toward the center of the lower side of the suction nozzle portion 30 to be connected to a point near the radial end of the upper surface of the first end of the functional insert 20. This allows an internal lever mechanism to be provided, and to enhance the displacement of the suction nozzle portion 30 from the functional insert with a smaller degree of rotation.

Figures 5A and 5B show further details of the functional insert 20. As shown in FIGS. 5A and 5B, the functional insert includes a housing 50 that houses various electronic components of the functional insert 20. In particular, the case 50 includes a first case part 51 and a second case part 52. The first shell part 51 and the second shell part 52 are arranged so that they are connected along a longitudinal interface that extends along the long axis of the functional insert 20. The first shell part 51 and the second shell part 52 thus enclose the functional electrical components in the shell 50. The first shell portion 51 and the second shell portion 52 include a thermoplastic material, thereby allowing the first shell portion 51 and the second shell portion 52 to be welded along the longitudinal interface to seal the shell 50 around the internal electronic components. In other examples of the present invention, the first shell portion 51 and the second shell portion 52 may include corresponding engagement structures configured to be attached to each other, thereby allowing the first shell portion 51 and the second shell portion 52 to releasably engage with each other To seal electronic components. For example, the engagement structure may allow a snap lock or friction fit connection between the shell parts 51, 52.

One or more parts of the housing parts 51, 52 may be removable to allow internal electrical components to be serviced, replaced, or repaired. The housing 50 of the functional insert 20 also includes a circumferential rim 53 extending around the outer surface of the housing 50 at the first end 24 of the functional insert 20. The functional insert rim 53 engages with corresponding features in the outer casing 10 to illustrate the retention of the functional insert 20 in the correct position within the outer casing 10, as will be described. As shown in FIG. 5B, the functional insert 20 further includes a longitudinal groove 54 extending along the outer surface of the shell in a direction corresponding to the long axis of the functional insert 20.

As shown in FIG. 5C, the first shell portion 51 and the second shell portion 52 may be offset relative to each other when assembled together. In other words, at least one of the distal ends of the first shell portion 51 and the second shell portion 52 is offset with respect to the other.

For example, as shown in FIG. 5D, one of the shell portions 51, 52 may be shorter than the other shell portion 51, 52. For example, the length distance can be between 50% and 75%. This allows some components to remain exposed when the first shell part 51 and the second shell part are assembled with each other. The exposed parts can be removed more easily when replacement is required, or can be assembled on the insert after the first shell part 51 and the second shell part 52 are attached to each other.

In this embodiment, only one of the shell parts 51, 52 contacts the bottom part of the shell sleeve. This also makes it possible to arrange a separate component in the bottom of the casing sleeve, such as an air channel piece or plug 300, as will be described in more detail in conjunction with FIGS. 7-9.

As shown in FIG. 6, the outer casing sleeve 10 further includes a circumferential protrusion 13 (ie, an inner rim on the inner surface of the casing) that extends radially inwardly from the inner surface of the outer casing sleeve 10 and It extends around the circumference of the inner surface near the first open end 11 of the outer casing sleeve 10. The circumferential protrusion 13 is arranged to meet the corresponding edge 53 of the functional insert 20 when the functional insert 20 is inserted into the outer casing sleeve 10 so that the functional insert 20 is retained in the outer casing sleeve 10. This ensures that the functional insert is held in the correct position along the length of the housing, for example to ensure that the cartridge holder opening 26 is aligned with the open end of the housing 10.

FIG. 6 also shows a guide rail 14 that extends along the long axis of the outer casing 10 along the inner surface from the circumferential protrusion 13 downward toward the closed end 12 in the outer casing sleeve 10. The guide rail 14 is configured to engage with a corresponding groove 54 in the outer surface of the housing 50 of the functional insert 20 shown in FIG. 5B. In this way, the functional insert 20 must be inserted into the outer housing 10 in the correct orientation so that the guide rail 14 engages the groove 54 to guide the functional insert 20 into the housing 10 so that it is held in the correct position . For example, this can be used to ensure that the functional insert 20 is correctly oriented in the device, and that, for example, the air inlet and charging port in the functional insert are correctly aligned with the corresponding orifices in the closed end 12 of the outer casing 10 . A plurality of guide rails 14 may be positioned around the circumference of the inner surface of the outer housing 10, wherein corresponding grooves 54 are arranged on the functional insert 20 to receive the guide rails. In the example of FIGS. 5 and 6, two guide rails 14 are provided on opposite surfaces in the outer housing 10, wherein corresponding grooves 54 are provided on the opposite surfaces along the long axis of the functional insert 20.

The outer casing sleeve 10 and the functional insert preferably further include means for fastening the functional insert 20 to the outer casing sleeve when the functional insert 20 is correctly received in the correct position in the outer casing sleeve 10. . In the example shown in Figures 5 and 6, both the outer casing sleeve 10 and the functional insert include fastening features in the form of apertures 15, 55. In particular, the orifice 15 is provided on the top surface of the guide rail 14 in the outer casing sleeve, and the corresponding orifice 55 is provided on the edge 53 of the functional insert, wherein the orifices 15, 55 are positioned as functional The insert 20 is aligned when received in the correct position within the outer casing sleeve 10. Then, the functional insert 20 can be fixed to the outer casing sleeve by fasteners such as screws, which are engaged through the two sets of apertures 15, 55. In this way, the functional insert 20 can be fixed within the outer casing sleeve 10 with a minimum of fastening means, thereby allowing the functional insert to be removed in a simple manner. FIG. 4 shows fasteners, in this case screws, which are positioned in the functional insert aperture 55 on the upper surface of the functional insert below the suction nozzle 30. In this way, the screws can be easily evaluated, thereby allowing the electronic cigarette 1 to be assembled in a simple manner.

As shown in FIG. 5B, the first end 24 of the functional insert 20 is preferably angled to provide a greater longitudinal length of the functional insert along the portion of the insert 20 that includes the cartridge holder 21. In other words, the functional insert 20 is shaped to have a varying length in the direction of elongation from the first end 24 to the second end 25. In particular, the inclined surface at the first end 24 provides a greater longitudinal length of the functional insert in the area including the cartridge holder 21. This allows the cartridge holder 21 to occupy a larger volume of the device, thereby allowing the device to receive a larger cartridge 40 for a longer duration of use. As mentioned above, the first cartridge holder 21 and the battery 22 are preferably positioned side by side in the functional insert 20. The battery and the first cartridge holder can be aligned along the long axis functional insert 20, thereby providing the most effective way to maximize the volume of the battery 22 and the elongate cartridge holder 21 in the functional insert 20 of a given size .

Figures 7 and 8 show alternative examples of the electronic cigarette 1 according to the present invention. As in the previous example, the electronic cigarette 1 includes an outer sleeve 100 having an open end and an opposite closed end 102. As in the previous embodiment, the outer casing 100 has an air inlet 117 positioned on the closed end. The electronic cigarette 1 further includes a functional insert 200 shown in FIG. 7A, which includes electronic components including a cartridge holder 221 arranged to receive a movable cartridge 40, wherein the functional insert 200 is arranged The component is introduced through the open end 101 of the outer casing sleeve 100 and is held in the casing sleeve 100 to form the electronic cigarette 1.

The examples of FIGS. 7 to 9 are different from the previously described electronic cigarette 1 in that they further include an air passage plug 210 which is arranged at the closed end 102 of the outer casing sleeve 100 and the functional insert 200 between the outer casing and the sleeve 100. The air passage plug 300 includes an air passage 310 that provides at least a part of the air flow path connecting the air inlet 117 of the outer casing 100 to the cartridge holder 221. The air passage plug 300 is a material plug that occupies a portion of the internal volume of the outer casing 100 at the first end 102. In particular, the air passage plug 300 may include a material piece that substantially fills the inner volume of the closed end 102 of the outer casing sleeve 100 and extends a certain length L1 from the closed end 102 toward the open end 101.

The air passage plug 300 serves a variety of purposes. First, the air passage plug is used to only allow air to flow into the device 1 through the defined air flow path 310. In some devices that do not include such air channel plugs, air can enter the device through openings in the cover (for example, the charging port), which results in a reduction in the pressure drop when inhaled through the suction nozzle, and may affect the production of aerosols and Correctly trigger the pressure sensor to activate the device. In addition, the air passage plug 300 may be used to protect the electrical components of the functional insert 200 by preventing contact between the functional insert 200 and the closed end in the outer casing sleeve 100.

By managing the air flow path through the air channel 310 in the air channel plug 300 into the device, it can be ensured that the airflow pressure applied by the suction at the mouthpiece is guided to the sensor, and the sensor is not passed through the air flu sensor The airflow from the opening at the base of the upper device is triggered. It also reduces the free internal volume of the device, which may cause the sensor to lack responsiveness. The air channel plug 300 is preferably made of an elastic deformable material such as an elastic material, which deforms into the shape of the internal volume in the outer casing 100 and provides shock absorption in the device to protect the electrical of the functional insert 200 part. The air passage plug 300 also provides a seal on the cross-section of the inner volume of the outer casing 100 so that the air flow into the outer casing 100 is restricted in addition to passing through the air passage 310. The air passage plug 300 preferably extends from the closed end 102 of the outer casing sleeve toward the open end over a length L1, which is equivalent to 25% of the total length L2 of the casing measured from the closed end 102 to the open end 101 above. This provides sufficient shock absorption to prevent damage due to accidental dropping of the device, and also has the advantage that the cartridge holder 221 can be appropriately placed and the cartridge air inlet can be arranged in the device.

The air channel 310 is preferably arranged so that it passes through the air channel plug 300, that is, the air channel passes through a deformable block of elastomeric material in the center. The air passage 310 and the air passage plug 300 containing the air passage can extend upward from the closed end of the device, so as to be sufficiently engaged with the inlet at the base of the cartridge holder, so that the air passage directly connects the air inlet of the outer shell 100 to the cartridge holder 221 air inlet (not shown). In other examples (such as the example shown in FIG. 7A), the elastomer material forming the air passage plug 300 may only extend a certain distance along the length of the housing, so that the air passage plug 300 and the air inlet of the cartridge holder 221 There is a gap and the open internal volume of the shell.

The functional insert 200 preferably contacts the air passage plug 300 within the outer casing sleeve to provide shock absorption and prevent significant contact between the functional insert and the outer casing sleeve, which may provide sufficient force to damage the components. More preferably, the functional insert 200 is engaged with the air passage plug 300 so that they are attached together, and the functional insert 200 and the air passage plug 300 can be assembled as an integral assembly, and then the integral assembly can be inserted and combined. It is fixed in the outer casing sleeve 100. In terms of simplicity of manufacture, this provides a significant advantage.

The connection between the functional insert 200 and the air passage plug 300 can be achieved in many different ways. In the example of FIG. 7A, the PCB 220 extends from the connection of the device with the battery 222 and the cartridge holder 221 along the long axis of the device 1 toward the second base end 102, where it is connected to the air passage plug 300 at the second base end. The groove 301 is engaged. In this way, the PCB 220 connected to the electronic component of the functional insert 200 extends downwardly along the long axis toward the closed end of the housing 100, and extends in the groove positioned in the air passage plug 300 holding the PCB, thereby A mechanical connection is provided between the functional insert 200 and the air passage plug 300.

The electronic cigarette 1 described above and in relation to FIGS. 7 and 8 may also include a charging port 302 to allow the device to be connected to a mains power source to charge the battery 222. In the example of FIGS. 7 and 8, the charging port 302 is provided in the air passage plug 300 and is connected to the electronic components of the functional insert 200 through the electrical circuit 303. This provides another connection between the air passage plug 300 and the functional insert 200. In particular, the charging port 302 is usually a metal orifice arranged to receive a power charger, and can be positioned wholly or partly within the elastomeric material of the air channel plug 300, with the open end of the charging port extending out of the base such that The charging port protrudes sufficiently to align with the aperture at the closed end 102 of the outer casing 100. The charging port 302 may be connected to the PCB 220 in the slot 301 in the air passage plug 300. In this way, using the existing features of these components, that is, without any additional fixing components, a mechanical and electrical connection is provided between the functional insert 200 and the air passage plug 300.

When the functional insert 200 and the connected air passage plug 300 are positioned in the outer casing sleeve 100 shown in FIG. 7B, the lower end 304 of the air passage plug 300 including the charging port 302 and the closed end of the outer casing sleeve 100 102's internal joints. The charging port 302 is aligned with a corresponding opening in the base of the outer casing 100, and the opening 217 of the air passage 310 of the air passage plug 300 is aligned with the air inlet 117 at the base of the closed end 102 of the outer casing 100.

As described above, in the example of FIGS. 7A and 7B, the nozzle portion 30 is provided at the first end 224 of the functional insert 200, wherein the nozzle portion 30 is hingedly connected to the functional insert, so that when the function is inserted When the piece 200 is received in the outer sleeve 100, the suction nozzle can move between the open position and the closed position shown in FIG. 7A. In the closed position, the open end 101 of the outer sleeve is sealed, and the second The cartridge holder 32 is connected to the first cartridge holder 221 of the functional insert 200. These components are described above with respect to FIGS. 1 to 6.

FIG. 8 schematically shows another example of the electronic cigarette 1, which includes a functional insert 200 and an air passage plug 300, and the air passage plug is received in the outer casing sleeve 100 to form the electronic cigarette 1. As described above, the air passage plug 300 includes a plug of elastic material positioned in the outer casing sleeve at the closed end to separate the inner surface of the closed end from the functional insert 200, and to provide shock absorption performance and countermeasures from the outer casing. The air flow path from the air inlet 117 at the closed end 102 of the sleeve 100 to the first cartridge holder 221 is controlled. As described above, the PCB 220 connected to the functional insert 200 extends downward along the long axis of the electronic cigarette 1 to engage with the groove 301, thereby providing a mechanical connection between the air passage plug 300 and the functional insert 200.

Fig. 8 further shows the gas and flu detector housing 240, which houses the gas and flu detector (shown in Fig. 9) in an internal cavity arranged to hold the gas and flu detector. The internal cavity of the holding air flu detector is in fluid communication with the first cartridge holder 221, so that the air flu detector is triggered when the user inhales at the mouthpiece 30. The air flu detector is also connected to the power source to switch on the power from the battery to the heater when a change in air pressure corresponding to the user's inhalation at the device is detected. As shown in FIG. 8, the air flue detector housing 240 also includes a separate air flow passage 241 that is not connected to the internal chamber. The air flow is connected to the air flow passage 310 in the air passage plug 300 through the passage 241. Therefore, the air flow through passage 241 of the air flue detector housing 240 and the air passage 310 of the air passage plug together provide an air flow path from the air inlet 117 of the outer casing 100 to the cartridge holder 221. The air flu detector housing 240 may also include a material similar to the air channel plug 300, such as an elastic deformable material such as an elastic material. The air passage plug 300 and the flue detector housing 240 together provide an air flow path from the inlet to the cartridge holder 221 and ensure that this does not pass through the flue detector. This prevents the inhalation detector from being triggered by the airflow through the inlet 117, but only by the decrease in the air pressure inhaled by the user at the mouthpiece, which is directly delivered to the inhalation detector housing The internal chamber. These features are described in more detail with reference to FIG. 9.

FIG. 9 shows an enlarged part of the base end 102 of the electronic cigarette 1 opposite to the mouth end 101. FIG. 9 shows the air passage plug 300 positioned between the functional insert 200 and the inner surface of the closed base end 102 of the outer shell 100. Similarly, the PCB 220 connected to the functional insert 200 extends down into the slot 301 of the air passage plug 300, and is connected to the charging port 302 via the electrical circuit 303, which is embedded in the air passage plug and can pass through the outer casing. The orifice at the base of the sleeve 100 enters.

FIG. 9 depicts the air flow path from the inlet 117 in the outer shell 100 to the cartridge holder 221 with a series of arrows A. FIG. 9 also shows the air flu sensor 242 positioned in the internal cavity 243 within the surrounding air sensor housing 240. As shown in the cross-sectional view of FIG. 9, the air flow detector cavity 243 is connected to the air flow path leading to the suction nozzle via the air flow cavity inlet 244. The air flow cavity inlet 244 extends upward from the cavity 243 in the sensor housing 240 toward the cartridge holder 221, for example, the pressure change caused by the user's inhalation is transmitted to the air flu detector cavity 243.

FIG. 9 also shows the air flow passage 241 passing through the air flue detector housing 240 from the air inlet 117. As clearly shown in the figure, the air flow is separated from the air flow detector chamber 243 through the passage 241 so that the air flow passing through the path does not pass through the air flow detector 242. This ensures improved functionality of the air flu detector 242, especially improved responsiveness.

In this example, the air passage plug 300 extends upward from the closed end 102 of the housing to meet the air flu detector housing 240. In addition, the air flow passage 310 provided in the air passage plug 300 directly connects the air inlet 117 in the outer casing 100 to the air flow passage 241 in the air flue detector housing 240. Therefore, the air passage plug 300 and the air flu detector housing 240 together form an air flow path from the air inlet to the cartridge holder 221. In particular, as shown by arrow A, air enters the air inlet 117, passes through the air flow channel 310 of the air channel plug 300, and the air flow entering the air flu detector housing 240 passes through the channel 241, and is guided to the base of the cartridge holder 221 In order to extract the vapor generated therein and carry it to the suction nozzle 30. Because there is no direct airflow through the airflow sensor from the inlet, the airflow sensor is more sensitive to changes in airflow pressure caused by inhalation at the mouthpiece.
