Description

A suction device

Technical Field

The present invention relates to the technical field of heat-not-burn tobacco, and in particular to a suction device.

Background technique

Traditional tobacco is generally ignited by a lighter or other igniter to produce an aerosol containing nicotine to satisfy consumers' inhalation. However, relevant studies have shown that the smoke produced by tobacco combustion contains a variety of carcinogens and a large number of other harmful substances, so that when consumers inhale such aerosols, it will affect their own health. For this reason, there are suction devices on the market that use low-temperature baking to heat cigarette bombs or other aerosol-generating products. While being able to produce aerosol containing nicotine to satisfy consumers, it effectively reduces the content of harmful substances contained in the aerosol. However, this type of suction device generally uses peripheral heating to heat cigarette bombs or other aerosol-generating products, that is, the outside of the cigarette bomb or other aerosol-generating products is heated.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

As shown in FIG1 , the present invention proposes a suction device, which includes: a shell 10, wherein the shell 10 has a heating end 12 and a transmission end 11, wherein the heating end 12 is provided with a heating cavity 13, and the transmission end 11 is provided with a transmission cavity 14; a heat transfer component 30, wherein the heat transfer component 30 is located in the shell 10, and wherein the heat transfer component 30 has a heat conductive member 31 (as shown in FIGS. 2 and 3 ) that penetrates from the transmission cavity 14 into the heating cavity 13, wherein the heat conductive member 31 and the inner wall of the heating cavity 13 form an accommodation gap 17 (as shown in FIG4 ); a feeding component 40, wherein the feeding component 40 is connected to the transmission end 11, wherein a combustion space (not marked in the figure) is provided on the feeding component 40, wherein one end of the heat transfer component 30 absorbs heat from the combustion space and transfers the heat to the heat conductive member 31.

In this embodiment, the transmission end 11 of the shell 10 is connected to the feed assembly 40, and the heat transfer assembly 30 is arranged in the shell 10. The heat transfer assembly 30 is provided with a heat conductor 31. The heat conductor 31 penetrates into the heating chamber 13 from the transmission chamber 14 opened on the shell 10. In the heating chamber 13, the heat conductor 31 and the inner wall of the heating chamber 13 form a receiving gap 17, and the receiving gap 17 is used to receive the cigarette cartridge (not shown in the figure). When the cigarette cartridge is located in the receiving gap 17, the heat conductor 31 is inserted into the interior of the cigarette cartridge. The feed assembly 40 is provided with a combustion space, and one end of the heat transfer assembly 30 absorbs the heat generated by the combustion of the fuel from the combustion space, and the heat is transferred to the heat conductor 31. The high temperature on the heat conductor 31 causes the cigarette cartridge inserted on the heat conductor 31 to produce inhalable gas, so as to achieve heating from the inside of the cigarette cartridge and effectively reduce the loss of heat.

In an optional embodiment, the combustion space is located in the transmission chamber 14, the supply assembly 40 stores fuel and transmits the fuel to the combustion space, and the portion of the heat transfer assembly 30 located in the transmission chamber 14 absorbs heat generated by the combustion space and transmits it to the heat conductor 31.

It can be understood that, in order to facilitate the insertion of the cigarette cartridge, the end of the heat conductive member 31 is set to be pointed, and the main body of the heat conductive member 31 is cylindrical, which is conducive to the full contact between the heat conductive member 31 and the cigarette cartridge and improves the heating efficiency. The heat conductive member 31 can pass through the entire cigarette cartridge or only penetrate a part of the cigarette cartridge.

Alternatively, the heat conducting member 31 may not form an accommodation gap 17 with the inner wall of the heating chamber 13, but a accommodation chamber may be directly provided on the heat conducting member 31, and the cigarette cartridge is heated in the accommodation chamber.

Furthermore, as shown in FIG. 4 , the heat transfer assembly 30 further includes a heat collecting member 32 connected to the heat conducting member 31 , and the heat collecting member 32 is disposed above the combustion space.

The heat collecting member 32 is connected to the heat conducting member 31 (as shown in FIG. 2 ). When the combustion space is located in the transmission chamber 14, the heat collecting member 32 is also located in the transmission chamber 14 to absorb the heat generated by the combustion of the fuel from the combustion space. In a specific implementation, a heat collecting chamber (not shown in the figure) is provided on the heat collecting member 32. The heat collecting chamber has an opening, which is arranged toward the combustion space. The heat collecting member 32 is covered above the combustion space, so that the combustion space is located in the heat collecting chamber provided by the heat collecting member 32 to fully absorb the heat. The heat is transferred to the heat conducting member 31 to heat the cigarette cartridge in the accommodating gap 17.

Specifically, as shown in FIG. 5 , the heat collecting member 32 is provided with exhaust holes 34 .

Since the combustion space is located in the heat collecting cavity provided on the heat collecting member 32, in order to immediately discharge the exhaust gas generated in the combustion space, the heat collecting member 32 is provided with an exhaust hole 34, and the combustion products are discharged from the exhaust hole 34. In this embodiment, the fuel used by the suction device can be a gas fuel, such as butane, or a liquid fuel, such as gasoline.

The heat conducting member 31 includes a heat conducting core 35 and a heat transfer shell 33 . The heat conducting core 35 is connected to the heat collecting member 32 , and the heat transfer shell 33 is wrapped around the surface of the heat conducting core 35 .

In one embodiment, the heat conductive element 31 includes a heat conductive core 35 and a heat transfer shell 33. The heat conductive core 35 is connected to the heat collecting element 32. The heat collecting element 32 transfers the absorbed heat to the heat conductive core 35. The heat transfer shell 33 is wrapped around the surface of the heat conductive core 35 to form an inner and outer layer. The inner layer is the heat conductive core 35, and the outer layer is the heat transfer shell 33. The heat transfer shell 33 is in direct contact with the cigarette cartridge to heat the cigarette cartridge to produce inhalable gas.

The heat-conducting core 35 is cylindrical, and has a connecting end 351 and a heat-conducting end 352 . The connecting end 351 is connected to the heat collecting element 32 . The heat-conducting shell 33 is disposed on the heat-conducting end 352 . The diameter of the connecting end 351 is smaller than that of the heat-conducting end 352 .

In a further solution, the heat-conducting core 35 is cylindrical, having a connecting end 351 and a heat-conducting end 352, the connecting end 351 is used to connect the heat collector 32, the heat-conducting shell 33 is wrapped on the heat-conducting end 352, and the heat-conducting end 352 is used to transfer heat to the heat-conducting shell 33. The diameter of the connecting end 351 is smaller than the diameter of the heat-conducting end 352, so that the heat-conducting shell 33 is only in contact with the heat-conducting end 352, not in contact with the connecting end 351, so that the heat-conducting shell 33 only obtains heat from the heat-conducting end 352 to improve the heating efficiency. After the cigarette cartridge is inserted into the accommodating gap 17, the position on the cigarette cartridge close to the connecting end 351 is the end of the cigarette cartridge, and the heat-conducting shell 33 cannot obtain heat from the connecting end 351, which effectively prevents the temperature of the end of the cigarette cartridge from being too high.

As shown in FIG4 , the heat transfer component 30 further includes a heat insulation sheet 36 , which is located between the heat collecting component 32 and the heat transfer shell 33 , and one end of the heat transfer shell 33 close to the heat collecting component 32 abuts against the heat insulation sheet 36 ; the heat insulation sheet 36 is made of ceramic, glass or stainless steel.

As an embodiment, the heat insulating sheet 36 is made of a material with low thermal conductivity, such as ceramic, glass or stainless steel. The heat insulating sheet 36 is located between the heat collecting component 32 and the heat transfer shell 33 to prevent the heat transfer shell 33 from directly obtaining heat from the heat collecting component 32, thereby preventing the temperature of the end of the cigarette cartridge close to the heat collecting component 32 from being too high, thereby improving the user's smoking experience.

It can be understood that in order for the heat conducting member 31 to pass from the transmission chamber 14 into the heating chamber 13 , a through hole (not shown in the figure) needs to be opened on the heat insulating sheet 36 , and the heat conducting member 31 passes through the through hole.

As an embodiment, the heat collecting element 32 and/or the heat conducting core 35 are made of metal with high thermal conductivity, such as copper or copper alloy metal material.

The heat collecting element 32 is connected to the heat conductive core 35 and can be integrally arranged with the heat conductive core 35. The heat collecting element 32 and/or the heat conductive core 35 are made of a metal with a high thermal conductivity coefficient to fully absorb heat and improve the utilization rate of fuel. The metal with a high thermal conductivity coefficient constituting the heat collecting element 32 and/or the heat conductive core 35 can be copper or copper alloy metal material.

The heat transfer shell 33 is made of a metal with a high expansion coefficient, such as aluminum or aluminum alloy, or one or more of stainless steel, nickel or chromium.

The heat transfer shell 33 has expansion properties and is made of a metal with a high expansion coefficient, such as one or more of aluminum or aluminum alloy, stainless steel, nickel or chromium. The expansion property of the heat transfer shell 33 causes the heat transfer shell 33 to expand and deform when the temperature is too high. At this time, the contact area between the deformed heat transfer shell 33 and the heat conductive core 35 becomes smaller, such as changing from the original surface contact to local point contact. After the contact area between the heat transfer shell 33 and the heat conductive core 35 becomes smaller, the heat obtained by the heat transfer shell 33 and the heat conductive core 35 decreases. When the temperature of the heat conductive core 35 drops, the expansion deformation of the heat transfer shell 33 gradually recovers, the contact area between the heat transfer shell 33 and the heat conductive core 35 increases, and the heat obtained by the heat transfer shell 33 and the heat conductive core 35 increases, so as to ensure the temperature stability in the heating chamber 13.

Furthermore, the outer surface of the heat transfer shell 33 is provided with a ceramic film or a glass glaze film coating to prevent the cigarette cartridge from adhering to the heat transfer shell 33. The surface of the heat collector 32 and/or the heat conductive core 35 is coated with an oxide film, which can protect the heat collector 32 and/or the heat conductive core 35 and prevent the heat collector 32 and/or the heat conductive core 35 from oxidation and rust.

In this embodiment, the suction device also includes a feed pipe 43, and a fuel chamber (not shown in the figure) is provided in the feed assembly 40. The feed pipe 43 is connected to the feed assembly 40 to connect the fuel chamber with the combustion space; the feed pipe 43 is penetrated in the transmission cavity 14, and one end of the feed pipe 43 is connected to the feed assembly 40, and the other end is provided with the combustion space.

As shown in FIG. 2 and FIG. 3 , in this embodiment, the fuel chamber stores fuel, such as butane or gasoline, and the delivery pipe 43 is arranged in the transmission chamber 14. One end of the delivery pipe 43 is connected to the fuel chamber, and the other end is provided with the combustion space. The delivery pipe 43 connects the fuel chamber with the combustion space, and the fuel in the combustion chamber enters the combustion space through the delivery pipe 43 for combustion. The combustion space is located in the transmission chamber 14, and the heat collecting member 32 is arranged above the combustion space to obtain the heat of the combustion space and transfer it to the heat conducting member 31.

Furthermore, one end of the feed pipe 43 having the combustion space is a combustion end 431, and the combustion end 431 is provided with an exhaust hole 34 (as shown in FIG. 7 ). A catalyst is provided on the exhaust hole 34 or the inner wall of the combustion space to enable the fuel to burn flamelessly in the combustion space.

The exhaust gas hole 34 on the combustion end 431 is used to discharge the exhaust gas generated by the combustion of the fuel. A catalyst is provided on the exhaust gas hole 34 or the inner wall of the combustion space to enable the fuel to burn flamelessly in the combustion space.

Specifically, the catalyst is loaded on a metal mesh or an asbestos mesh, and the metal mesh or the asbestos mesh is installed in the combustion space; the catalyst is platinum nanoparticles.

The catalyst can be loaded on a metal mesh or asbestos mesh, and then the metal mesh or asbestos mesh is installed in the combustion space to catalyze the combustion of the fuel, so that the fuel undergoes low-temperature flameless combustion. The catalyst can be platinum nanoparticles. In a preferred embodiment, the heat transferred from the heat collector 32 to the heat conductor 31 makes the temperature in the heating chamber 13 lower than 350 degrees Celsius.

Optionally, as shown in Figure 6, the feeding assembly 40 has a feeding part 41 and a storage part 42, the fuel chamber includes a feeding chamber 46 and a storage chamber 47, the feeding chamber 46 is opened in the feeding part 41, and the storage chamber 47 is opened in the storage part 42, and the feeding chamber 46, storage chamber 47 and combustion space are connected in sequence.

The feeding assembly 40 includes a feeding member 41 and a storage member 42. A feeding chamber 46 is provided on the feeding member 41, and a storage chamber 47 is provided on the storage member 42. The storage chamber 47 provides fuel for the combustion space, and the stored fuel can heat one or more cigarette cartridges. In an optional embodiment, the volume of the storage chamber 47 can be used to store the fuel required to heat a cigarette cartridge, or can provide 3-5 minutes of burning time. After the user smokes a cigarette cartridge, the fuel in the storage chamber 47 is exhausted, and the suction device can automatically extinguish, simplifying the user operation. The volume of the feeding chamber 46 is greater than or equal to the volume of the storage chamber 47, and can store more fuel, providing fuel for the storage chamber 47. After the fuel in the storage chamber 47 is exhausted, the fuel in the feeding chamber 46 is filled into the storage chamber 47. The feeding chamber 46, the storage chamber 47 and the combustion space are connected in sequence, that is, the storage chamber 47 is located between the feeding chamber 46 and the combustion space. The volume of the supply chamber 46 is several times, for example, 10 times, the volume of the storage chamber 47 . The fuel in the supply chamber 46 can be used to replenish the storage chamber 47 10 times. When the fuel in the storage chamber 47 is used up, fuel can be injected into the storage chamber 47 through the supply chamber 46 .

In one embodiment, an air valve 60 is provided between the storage element 42 and the material delivery pipe 43 (as shown in FIG. 3 ).

The gas valve 60 is located between the storage element 42 and the feed pipe 43. The fuel in the storage chamber 47 enters the combustion space through the gas valve 60. At the same time, air enters from the gas valve 60 and mixes with the fuel. The mixture of fuel and air burns in the combustion chamber to generate exhaust gas and is discharged from the exhaust hole 34. In a specific implementation, the gas valve 60 is provided with a feed hole (not shown in the figure) and an air inlet hole (not shown in the figure). The feed hole connects the feed pipe 43 and the storage chamber 47. The fuel enters the combustion space through the feed hole. The air inlet hole is located on the side wall of the gas valve 60 and is used to introduce air into the feed pipe 43 so that the fuel and air are fully mixed and can be fully burned. The number of air inlet holes can be set as needed. Generally, the more air inlet holes there are, the more air enters the feed pipe 43. In an optional embodiment, the aperture of the feed hole is of a variable diameter type, for example, the aperture of the inlet end and the outlet end of the feed hole are both larger than the aperture of the middle position of the feed hole, or the aperture of the feed hole gradually decreases from the inlet end to the outlet end. The variable diameter feed hole allows the fuel to be ejected at high speed from the position with the smallest aperture on the feed pipe 43, generating a Venturi effect. The fuel flows at high speed at the position with the smallest aperture to generate low pressure, which has an adsorption effect, and the surrounding air automatically enters the feed pipe 43 from the inlet hole to mix with the fuel.

Specifically, the minimum aperture of the feed hole is greater than or equal to 50 um and less than or equal to 100 um. Any value within this numerical range can cause the Venturi effect when the fuel flows through the minimum aperture, such as 60 um or 80 um.

The transmission end 11 is provided with a switch 16 , the switch 16 is connected to the air valve 60 , and the switch 16 adjusts the opening size of the material delivery hole.

The switch 16 is disposed at the transmission end 11 of the housing 10, and is connected to the gas valve 60, and is used to adjust the opening size of the feed hole. In a specific implementation, the switch 16 adjusts the opening size of the air inlet end of the feed hole. The larger the opening, the more fuel enters the combustion space, the higher the temperature in the heating chamber 13, and the more inhalable gas produced by the smoke bomb. The specific setting form of the switch 16 can be a hand wheel or a dial block.

Optionally, the feeding assembly 40 further includes a connecting member 45 , and the connecting member 45 is located between the feeding member 41 and the storage member 42 .

The connecting member 45 is located between the supply member 41 and the storage member 42 , and is used to connect the supply member 41 and the storage member 42 , and to communicate the storage chamber with the supply chamber 46 . The fuel enters the storage chamber 47 from the supply chamber 46 through the connecting member 45 .

In a further embodiment, the connecting member 45 includes a connecting pipe 452, and the connecting pipe 452 and the storage chamber 47 have a connected state and a disconnected state. The feeding member 41 has a discharge port (not shown in the figure), and an air outlet valve (not shown in the figure) is installed on the discharge port. The storage member 42 is provided with a feed port (not shown in the figure), and an air intake valve (not shown in the figure) is installed on the feed port.

The connecting pipe 452 connects the feeding chamber 46 and the storage chamber 47. The feeding member 41 has a discharge port. The fuel in the feeding chamber 46 is filled into the storage chamber 47 through the discharge port and the feed port. The discharge port can be equipped with an air outlet valve. The feed port of the storage chamber 47 can be equipped with an air charging valve. When the connecting pipe 452 and the storage chamber 47 are in a connected state, the air outlet valve and the air charging valve are opened, and the fuel in the feeding chamber 46 enters the storage chamber 47; when the connecting pipe 452 and the storage chamber 47 are disconnected, the air outlet valve and the air charging valve are closed.
