[0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium.

[0003] At present, a general aerosol generating device can only hold one aerosol substrate. When the aerosol substrate is used up, the aerosol generating device needs to be disassembled. Since an aerosol substrate has a short service life, it is very troublesome to replace the aerosol substrate. If an external substrate box is installed outside the aerosol generating device, the volume of the aerosol generating device is easily increased, which greatly affects the user experience. Summary of the invention

[0014] Furthermore, a bullet outlet and a bullet pushing port are arranged on the side wall of the bullet outlet nozzle adjacent to the main body, and the bullet outlet and the bullet pushing port are arranged opposite to each other.

[0015] Furthermore, a clearance groove communicating with the redirection channel is provided at one end of the ejection nozzle away from the main body, and two ends of the clearance groove are respectively communicated with the ejection port and the ejection port; a limit block for preventing the aerosol substrate from escaping from the clearance groove is provided on one side of the clearance groove close to the ejection port.

[0016] Furthermore, the pushing member is an elastic member, one end of the elastic member is connected to the elastic supporting member, and one end of the elastic member away from the elastic supporting member is connected to the side wall of the accommodating cavity.

[0036] Example

[0037] like Figures 1 to 5 As shown, the present invention provides an aerosol substrate automatic filling mechanism, which includes:

[0038] A body 10, wherein the body 10 is provided with a receiving cavity 11;

[0039] A bullet ejection nozzle 20 disposed on the body 10;

[0040] A pushing assembly 30 disposed in the accommodating chamber 11, the pushing assembly 30 comprises a bullet-holding member 31 slidably disposed in the accommodating chamber 11 and a pushing member 32 for controlling the bullet-holding member 31 to approach or move away from the bullet-discharging nozzle 20;

[0041] A spiral direction-changing channel 23 is provided between the ejection nozzle 20 and the accommodating chamber 11 , and the direction-changing channel 23 is used to rotate the direction of the aerosol substrate 40 .

[0042] The reason why the aerosol substrate 40 needs to be rotated is that in the aerosol generating device, in order to facilitate the realization of the smoke airway in the up and down directions, air holes are set on the upper and lower end surfaces of the cylindrical aerosol substrate 40. After the aerosol substrate is heated, the airflow enters the interior of the aerosol substrate from the lower end surface of the aerosol substrate 40, driving the smoke out from the upper end surface of the aerosol substrate 40, and then inhaled by the user. The aerosol substrate 40 is placed horizontally in the accommodating chamber 11. Compared with the vertical placement, the number of aerosol substrates 40 that can be stored is larger, and the structure of the pushing component 30 can also be relatively simple. Because of the vertical placement, there may be only one row of aerosol substrates 40, so there are relatively few aerosol substrates 40; if two or more rows are to be placed, a very complex structure may be required to achieve the push-out of aerosol substrates 40 in different rows. The aerosol substrate automatic filling mechanism can place the aerosol substrate 40 in the accommodating chamber 11, and then the aerosol substrate 40 can be pushed out from the ejection nozzle 20 through the pushing component 30. The aerosol substrate 40 is output in the simplest, most reliable and stable manner on the basis of reasonable ergonomics. The aerosol substrate automatic filling mechanism has a large storage capacity and stable loading, which can significantly reduce production costs and maintenance costs.

[0043] like Figure 3 and Figure 5 As shown, the ejection direction of the ejection nozzle 20 intersects with the sliding direction of the ejection support member 31, and a push channel 12 is provided between the deflection channel 23 and the accommodating chamber 11, and the push channel 12 is used to guide the aerosol substrate 40 in the accommodating chamber 11 to slide to the ejection nozzle 20 under the action of the push assembly 30. Specifically, the ejection direction of the ejection nozzle 20 is the relative movement direction of the aerosol substrate 40 in the ejection nozzle 20. Specifically, the ejection direction of the ejection nozzle 20 is perpendicular to the sliding direction of the ejection support member 31. The ejection nozzle 20 is connected to the body 10 in an L-shape, which can reduce the volume of the whole machine, ensure the strength and reliability of the automatic filling mechanism of the aerosol substrate, and solve the problem that the internal space of the whole smoke machine is large and difficult to hold due to the direction of the ejection nozzle 20 of the automatic filling mechanism of the aerosol substrate.

[0044] Combination Figure 3 As shown, the thickness of the push channel 12 gradually decreases from the accommodating cavity 11 to the bullet outlet nozzle 20, and the bending part of the push channel 12 is a smooth arc surface; in this embodiment, the thickness of the push channel 12 gradually decreases from the accommodating cavity 11 to the bullet outlet nozzle 20, and finally only a single aerosol substrate 40 is allowed to enter the bullet outlet nozzle 20, thereby preventing the aerosol substrate 40 from being blocked and stuck in the bullet outlet nozzle 20.

[0045] Preferably, the accommodating chamber 11 is provided with at least one filling dummy bullet 13 having the same shape as the aerosol substrate 40, the thickness of the push channel 12 on the side close to the accommodating chamber 11 is greater than the outer diameter of the filling dummy bullet 13, and the thickness of the push channel 12 on the side close to the bullet outlet 20 is equal to the outer diameter of the filling dummy bullet 13. In this embodiment, the filling dummy bullet 13 is exactly the same shape as the aerosol substrate 40, the thickness of the accommodating chamber 11 is greater than the diameter of one aerosol substrate 40 and less than the diameter of two aerosol substrates 40, the width of the accommodating chamber 11 is equal to the length of the aerosol substrate 40, and the aerosol substrate 40 is stacked and placed in the accommodating chamber 11, which can make full use of the space of the accommodating chamber 11, reduce the volume of the whole machine, and facilitate the aerosol substrate 40 to slide to the push channel 12 along the length direction of the accommodating chamber 11. The filling dummy bullet 13 can be used to fill the space of the push channel 12 to prevent the last aerosol substrate 40 from remaining in the push channel 12 and being unable to detach from the bullet outlet 20. In this embodiment, two layers of aerosol substrates 40 can be placed in the accommodating cavity 11, and the upper and lower stacked aerosol substrates 40 are staggered. The advantage of the staggered arrangement is that it can avoid jamming, such as two aerosol substrates 40 being stuck in the pushing channel 12. In other embodiments, there can also be more layers of aerosol substrates 40.

[0046] In this embodiment, in order to achieve the above-mentioned vertically offset arrangement of the sol substrate 40, a slope is provided on the side of the elastic support member 31 away from the pushing member 32. By utilizing this slope, when the aerosol substrate 40 is pushed outward, the remaining aerosol substrate 40 can effectively maintain the vertically offset stacking state.

[0047] like Figures 1 to 4 As shown, a bullet outlet 21 and a bullet push port 22 are provided on the side wall of the bullet outlet 20 adjacent to the body 10, and the bullet outlet 21 and the bullet push port 22 are arranged opposite to each other. Specifically, after the aerosol substrate 40 enters the bullet outlet 20, the aerosol substrate 40 can be pushed out of the bullet outlet 21 and sent into the heating cup by the ejector pin of the main unit, which is beneficial to reducing the volume of the main unit.

[0048] Specifically, the ejection direction of the ejection port 21 is the same as the direction in which the ejection support 31 pushes the aerosol substrate 40. A direction-changing channel 23 for changing the direction of the aerosol substrate 40 is provided in the ejection nozzle 20. The direction-changing channel 23 is spiral-shaped, and one end of the direction-changing channel 23 is connected to the pushing channel 12. In this embodiment, when the aerosol substrate automatic filling mechanism is installed on the host, the body 10 is attached to the host, and the length direction of the body 10 is parallel to the length direction of the host. At this time, the length direction of the aerosol substrate 40 is perpendicular to the length direction of the host. Through the direction-changing channel 23, the aerosol substrate 40 can change its direction when it is separated from the ejection nozzle 20, so that the length direction of the aerosol substrate 40 is in the same direction as the length direction of the host. Therefore, the redirecting channel 23 is spiral and can only allow one aerosol substrate 40 to pass through. Under the action of the pushing component 30, the aerosol substrate 40 enters the redirecting channel 23 from the accommodating chamber 11 through the 90-degree bend of the pushing channel 12. Then, under the action of the pushing component 30, the aerosol substrate 40 rotates 90 degrees in the redirecting channel 23, and the length direction of the aerosol substrate 40 is in the same direction as the length direction of the main machine.

[0049] In this embodiment, if Figures 2 to 4 As shown, the bullet discharge nozzle 20 includes a shell 24, a first guide block 25 and a second guide block 26 arranged in the shell 24, the bullet discharge port 21 and the bullet push port 22 are located on the shell 24, and the direction of the line connecting the bullet discharge port 21 and the bullet push port 22 is in the same direction as the length direction of the main body 10. The shell 24 is provided with a latching tooth 241 that is engaged with the external host, so as to facilitate the installation of the aerosol substrate automatic filling mechanism on the host. The first guide block 25 and the second guide block 26 are respectively located on both sides of the push channel 12, and a spiral turning channel 23 is formed between the first guide block 25 and the second guide block 26. The aerosol substrate 40 passes through the push channel 12 from the accommodating chamber 11, bends 90 degrees to enter the turning channel 23, and then under the action of the push assembly 30, as shown in detail. Figure 4Taking the perspective as an example, the first guide block 25 and the second guide block 26 are provided with a slide groove to form a spiral redirection channel 23. When the aerosol substrate 40 enters the redirection channel 23, the aerosol substrate 40 crosses the first guide block 25 and the second guide block 26 and is located at the top of the slide groove (assuming that the end of the aerosol substrate 40 that contacts the second guide block 26 is the top of the aerosol substrate 40, and the end that contacts the first guide block 25 is the bottom of the aerosol substrate 40). A force is applied to the aerosol substrate 40, and the top of the aerosol substrate 40 slides to the left along the slide groove of the second guide block 26; the bottom of the aerosol substrate 40 slides to the right along the slide groove of the first guide block 25. Finally, the aerosol substrate 40 is located between the first guide block 25 and the second guide block 26. The aerosol substrate 40 rotates 90 degrees in the redirection channel 23, and the length direction of the aerosol substrate 40 is in the same direction as the length direction of the host. By providing the casing 24 , the first guide block 25 and the second guide block 26 , the nozzle 20 can be easily assembled.

[0050] In this embodiment, the sleeve 24, the first guide block 25 and the second guide block 26 are integrally injection molded by injection molding technology, so that the direction-changing channel 23 is integrated with the push channel 12. In other embodiments, the nozzle 20 can also be assembled by gluing or ultrasonic welding.

[0051] like Figure 1 As shown, the end of the ejection nozzle 20 away from the body 10 is provided with a clearance groove 27 communicated with the redirection channel 23, and the two ends of the clearance groove 27 are respectively communicated with the ejection port 21 and the ejection port 22; the side of the clearance groove 27 close to the ejection port 22 is provided with a stop block 28 for preventing the aerosol substrate 40 from escaping from the clearance groove 27. Specifically, the end of the sleeve 24 away from the body 10 is provided with an opening to form the clearance groove 27. Two stop blocks 28 are provided, and are respectively located on the first guide block 25 and the second guide block 26. When the aerosol substrate 40 slides to the end of the ejection nozzle 20, the end close to the ejection port 21 has no stop block 28, and the aerosol substrate 40 partially protrudes from the ejection nozzle 20, which is convenient for entering the main unit; the end of the aerosol substrate 40 close to the ejection port 22 is blocked by the stop block 28, which can prevent the aerosol substrate 40 from escaping from the aerosol substrate automatic filling mechanism when the main unit is not connected. Furthermore, through this arrangement, it is convenient to load bullets from the bullet outlet 20 and the bullets can be used repeatedly.

[0052] like Figure 2 and Figure 3As shown, the pushing member 32 is an elastic member, one end of the elastic member is connected to the spring-supporting member 31, and the end of the elastic member away from the spring-supporting member 31 is connected to the side wall of the accommodating cavity 11. The spring-supporting member 31 matches the shape of the pushing channel 12. When the elastic member is in a natural state, the spring-supporting member 31 is located in the pushing channel 12. Specifically, the elastic member can be a spring, and the cross section of the spring is square, which is not easy to loosen in the accommodating cavity 11, and automatic loading can be completed under the action of the spring.

[0053] In this embodiment, in order to facilitate the assembly of the push assembly and the loading of the bullet, the body 10 is provided with an opening communicating with the accommodating chamber 11, and the opening is located on the side of the accommodating chamber 11 away from the pushing channel 12. The body 10 is detachably connected with a sealing cover 14 for closing the opening, and one end of the elastic member away from the bullet-supporting member 31 is connected to the sealing cover 14. A card slot is provided at one end of the body 10 away from the bullet-discharging nozzle 20, and the sealing cover 14 is provided with a card block engaged with the card slot. In other embodiments, the sealing cover 14 and the body 10 can be connected by threads to facilitate the removal of the sealing cover 14. A supporting plate 15 is provided in the sealing cover 14 to facilitate the fixing of the end of the spring.

[0054] like Figure 1 As shown, the body 10 is provided with a magnetic member 16, and the magnetic member 16 and the ejection nozzle 20 are located on the same side of the body 10. The magnetic member 16 can be attracted to the host, and the automatic filling mechanism of the aerosol substrate is installed on the host more stably.

[0055] The present embodiment also relates to an aerosol generating device, comprising a main unit and the above-mentioned aerosol substrate automatic filling mechanism detachably connected to the main unit.

[0056] It can be understood that the working principle of this aerosol substrate automatic filling mechanism is roughly as follows: when the aerosol substrate 40 slides to the end of the bullet outlet 20, the end close to the bullet outlet 21 has no limit block 28, so the aerosol substrate 40 partially protrudes out of the bullet outlet 20, which is convenient for entering the main unit. The end of the aerosol substrate 40 close to the push port 22 is blocked by the limit block 28, which can prevent the aerosol substrate 40 from detaching from the aerosol substrate automatic filling mechanism when the main unit is not connected. Specifically, a heating cup and an aerosol substrate ejector pin are provided on the main unit. After the aerosol substrate 40 comes out of the aerosol substrate automatic filling mechanism, the aerosol substrate ejector pin is pulled upward to push the aerosol substrate 40 into the heating cup. Then, the heating cup is controlled to work so as to heat the aerosol substrate to generate smoke. The aerosol substrate firing pin can be connected to a spring and can slide the aerosol substrate firing pin up and down. In a natural state, under the action of the spring, the aerosol substrate firing pin can cover the ejection nozzle 20. The ejection nozzle 20 can be exposed by pulling down the firing pin. The firing pin rebounds upward to push the aerosol substrate 40 at the end of the ejection nozzle 20 into the heating cup. The heating body is connected to the filter tip of the main unit. After inhaling an aerosol substrate 40, the filter tip is removed and the aerosol substrate can be poured out from the filter tip.

[0057] In summary, compared with the prior art, the aerosol substrate automatic filling mechanism has at least the following beneficial effects:

[0058] First, the aerosol substrate automatic filling mechanism can place the aerosol substrate 40 in the accommodating chamber 11, and then push the aerosol substrate 40 out of the ejection nozzle 20 through the pushing component 30, and output the aerosol substrate 40 in the simplest, most reliable and stable manner on the basis of reasonable ergonomics. The aerosol substrate automatic filling mechanism has a large storage capacity and stable ejection, and has the advantages of significantly reducing production costs and maintenance costs;

[0059] Secondly, the automatic filling mechanism of the aerosol substrate does not require a large number of transmission parts to support it, so it is low in cost and simple to process;

[0060] Thirdly, the nozzle is connected to the body 10 in an L shape, which can reduce the volume of the whole machine, ensure the strength and reliability of the aerosol substrate 40 box, and solve the problem that the internal space of the whole smoke machine is large and difficult to hold due to the direction of the ejection port 21 of the automatic filling mechanism of the aerosol substrate.

[0061] All technical features in this embodiment can be freely combined according to actual needs.

[0062] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
