[0033] The preferred implementation of the present application is described below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, a heating device 100 with a cleaning function is shown in one embodiment of the present application, which can be applied to low-temperature roasted tobacco electronic cigarettes.

[0035] like Figure 1 As shown, the heating device with cleaning function 100 includes a housing 110 , a battery assembly 180 , a heating assembly 120 , a sealing assembly 130 and a tar collecting member 140 .

[0036] The housing 110 is a hollow structure with a cigarette insertion port 113 at one end, which is used to protect the battery assembly 180, the heating assembly 120, the sealing assembly 130 and the tar collecting member 140 located inside the housing 110. Figure 1 As shown, the housing 110 includes a casing 111 and an end cover 112, wherein the end cover 112 covers the casing 111 and is provided with a cigarette insertion port 113. The cigarette insertion port 113 is used to place tobacco into the interior of the heating device 100 and inhale the aerosol generated by the heating device 100.

[0037] The battery assembly 180 is located inside the housing 110 and is used to store and release electrical energy, and can provide electrical energy for the heating device 100 to heat tobacco to generate aerosol.

[0038] like Figure 1 As shown, the heating component 120 is located inside the housing 110. Figure 1 and Figure 2 As shown, the heating component 120 includes a heating element 121 and a bracket 122. A cigarette insertion channel 123 connected to the cigarette insertion port 113 is provided in the bracket 122, and the cigarette insertion channel 123 is used to place tobacco. The heating element 121 surrounds the outside of the bracket 122. The heating element 121 is connected to the battery assembly 180 so that the battery assembly 180 provides electrical energy to the heating element 121. A through hole 1221 is provided at the top of the side wall of the bracket 122.

[0039] As a cleaning method, the battery assembly 180 can provide electrical energy to the heating element 121, so that the heating element 121 generates a high temperature of 450°C or above to bake the heating component 120, thereby vaporizing and volatilizing the tar, thereby achieving the purpose of cleaning the tar on the surface of the heating component 120.

[0040] like Figure 2 As shown, the sealing component 130 is located inside the housing 110, and the sealing component 130 is enclosed outside the heating component 120 to isolate the heating component 120 and the housing 110, so that the tar formed by the heating component 120 heating the tobacco cannot flow out of the sealing component 130. When cleaning the heating component 120, a cleaning liquid can be poured into the cigarette insertion channel 123, and the tar on the surface of the bracket 122 and the heating element 121 can be flushed by the cleaning liquid, and the sealing component 130 prevents the cleaning liquid from flowing out of the sealing component 130.

[0041] like Figure 1 and Figure 2As shown, the tar collecting member 140 is located inside the sealing assembly 130. The tar collecting member 140 is detachably mounted on one end of the cigarette insertion passage 123 away from the cigarette insertion port 113. The tar collecting member 140 is disposed toward the cigarette insertion port 113. When the aerosol generated by the heating device 100 is inhaled from the cigarette insertion port 113, the cigarette insertion port 113 is disposed upward. Under the action of gravity, the tar formed by the heating component 120 heating the tobacco can flow into and collect in the tar collecting member 140. Since the tar collecting member 140 is disposed toward the cigarette insertion port 113, the tar collecting member 140 can be wiped and cleaned by inserting a cotton swab or the like without disassembling the tar collecting member 140. The tar collecting member 140 is detachably mounted on the cigarette insertion passage 123. When the tar collecting member 140 is used for a long time, the tar collecting member 140 can be disassembled and replaced to achieve the purpose of cleaning the tar.

[0042] According to some embodiments of the present application, the tar collecting member 140 is optionally made of a flexible material. In this embodiment, the tar collecting member 140 is made of a silicone material to facilitate the removal and installation of the tar collecting member 140. In other embodiments, the tar collecting member 140 may also be made of other resin materials.

[0043] According to some embodiments of the present application, optionally, the tar collecting piece 140 is provided with a pin (not shown in the figure) facing the cigarette insertion port 113, and the pin and the tar collecting piece 140 are fixedly connected or an integral structure, and the pin extends along the inner side wall of the bracket 122 toward the cigarette insertion port 113 to facilitate clamping the pin and thereby driving the tar collecting piece 140 to be removed.

[0044] The above scheme can seal the heating component 120 by providing the sealing component 130, so that the heating component 120 is only connected to the cigarette insertion port 113, so that when cleaning the heating component 120, the cleaning liquid is poured into the cigarette insertion channel 123, and the tar on the surface of the bracket 122 and the heating element 121 is washed by the cleaning liquid. The sealing component 130 prevents the cleaning liquid from flowing out of the sealing component 130 to avoid damaging the battery component 180, etc. The tar collecting member 140 facing the cigarette insertion port 113 is also provided, so that the tar formed by the heating component 120 heating tobacco can flow into and collect in the tar collecting member 140, so that the tar collecting member 140 can be wiped and cleaned by inserting a cotton swab or the like without removing the tar collecting member 140, and the tar collecting member 140 is detachably installed in the cigarette insertion channel 123, and when the tar collecting member 140 is used for a long time, the tar collecting member 140 can be removed and replaced to clean the tar.

[0045] like Figure 2 and Figure 5As shown, according to some embodiments of the present application, optionally, the sealing assembly 130 includes an isolation column 131, an upper sealing member 132 and a lower sealing member 133. The isolation column 131 is sleeved on the outside of the heating component 120, a heating chamber 135 is formed between the isolation column 131 and the bracket 122, and the upper sealing member 132 and the lower sealing member 133 are respectively connected to the upper and lower ends of the bracket 122. In this embodiment, the upper sealing member 132 and the lower sealing member 133 are both made of rubber material.

[0046] like Figure 1 and Figure 2 As shown, the isolation column 131, the upper seal 132 and the lower seal 133 surround the heating component 120, and the upper seal 132 is an annular structure to connect the cigarette insertion channel 123 with the cigarette insertion port 113. The lower seal 133 is also an annular structure to place the tar collection member 140.

[0047] The through hole 1221 of the bracket 122 communicates with the heating chamber 135 and the cigarette insertion channel 123, so as to provide an air flow channel when the aerosol generated by the heating device 100 is inhaled, thereby achieving gas flow. Figure 1 and Figure 2 As shown, the through hole 1221 is located at the top end of the side wall of the bracket 122 .

[0048] like Figure 3 As shown, according to some embodiments of the present application, optionally, the tar collecting member 140 is a hollow cylindrical structure, so that the tar is collected and gathered at the bottom of the tar collecting member 140. The top side wall of the tar collecting member 140 is provided with a through hole 141, and the through hole 141 connects the heating chamber 135 and the cigarette insertion channel 123, so as to provide an air flow channel when the aerosol generated by the heating device 100 is inhaled, so as to realize gas flow.

[0049] like Figure 3 and Figure 4 As shown, a tar barrier strip 143 is convexly disposed on the inner side of the side wall of the tar collecting member 140. The tar barrier strip 143 surrounds the through hole 141 to prevent tar from flowing into the through hole 141. Figure 3 and Figure 4 In the illustrated embodiment, the tar blocking strips 143 extend along the inner side of the side wall of the tar collecting member 140 to the bottom. There are gaps between adjacent tar blocking strips 143, and the gaps are used for tar to flow into the interior of the tar collecting member 140.

[0050] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, optionally, the sealing assembly 130 further includes a support member 134, and the support member 134 is connected to one end of the isolation column 131 close to the tar collecting member 140, such as Figure 2As shown, except for the hole through which the heating element 121 penetrates the sealing component 130 to connect the battery component 180, the support member 134 closes the bottom end of the isolation column 131, so that the sealing component 130 is only connected to the top cigarette insertion port 113, and is not connected to other spaces in the housing 110. The tar collecting member 140 is placed on the support member 134.

[0051] It is understandable that, although the heater 121 penetrates the sealing assembly 130 to connect the battery assembly 180 and needs to set corresponding holes in the lower sealing member 133 and the support member 134, the lower sealing member 133 has a certain degree of elasticity, and the lower sealing member 133 and the heater 121 can be used in an interference fit manner to achieve a sealing effect, so that the heater 121 penetrates the sealing assembly 130 without affecting the sealing effect. In other embodiments, a sealing member, such as a sealing ring, can also be set at the connection between the heater 121 and the lower support member 134 to achieve a sealing effect, so that the heater 121 penetrates the sealing assembly 130 without affecting the sealing effect.

[0052] like Figure 2 As shown, a support protrusion 1341 facing the cigarette insertion port 113 is provided on one side of the support member 134 located inside the isolation column 131. The support protrusion 1341 penetrates the lower sealing member 133. Preferably, there are multiple support protrusions 1341, which are arranged circumferentially along the central axis of the tar collecting member 140, and the multiple support protrusions 1341 are arranged at intervals. The gap between adjacent support protrusions 1341 is adapted to the position of the through hole 141, so that the through hole 141 can connect the heating chamber 135 and the cigarette insertion channel 123. A support ring 142 is provided at the top of the tar collecting member 140, as shown in FIG. Figure 2 and Figure 3 As shown, the support ring 142 is formed by the outward turn of the top end of the tar collecting member 140, and the support ring 142 is adapted to the support protrusion 1341 so that the support ring 142 of the tar collecting member 140 can be placed on the support protrusion 1341. At this time, the support ring 142 abuts against the support protrusion 1341, so that the support member 134 can support the tar collecting member 140.

[0053] like Figure 1 and Figure 2 As shown, the support member 134 also supports the bracket 122, and a step groove is provided at the connection between the support protrusion 1341 and the bracket 122. The bottom end of the inner wall of the bracket 122 is provided with a step groove that matches the step groove. The step groove is embedded in the step groove so that the support member 134 supports the bracket 122 and limits the bracket 122 in the circumferential direction of the central axis to prevent the bracket 122 from displacement.

[0054] like Figure 1 , Figure 2 and Figure 5According to some embodiments of the present application, optionally, the heating device 100 with a cleaning function further includes a supporting assembly 150, which is located inside the shell 110 and is sleeved on the outside of the sealing assembly 130, and serves to support the sealing assembly 130 and the heating assembly to prevent the heating assembly and the sealing assembly 130 from shifting inside the shell 110.

[0055] According to some embodiments of the present application, optionally, the support assembly 150 includes a support column 151, a lower support platform 152 and an upper support platform 153, the sealing assembly 130 is located inside the support column 151 and mounted on the lower support platform 152, and the upper support platform 153 is located at the top of the sealing assembly 130. Figure 1 and Figure 2 As shown, the support member 134 of the sealing assembly 130 is mounted on the lower support platform 152. Figure 1 and Figure 2 In the illustrated embodiment, the lower support platform 152 is provided with an annular protrusion axially arranged along the central axis, the bottom end radius of the support member 134 gradually decreases to match the annular protrusion, and the bottom end of the support member 134 is inserted into the annular protrusion so that the lower support platform 152 axially supports the support member 134, and the annular protrusion can limit the support member 134 in the circumferential direction of the central axis to prevent displacement.

[0056] like Figure 1 , Figure 2 and Figure 5 As shown, according to some embodiments of the present application, optionally, a top seal 160 is provided between the upper support platform 153 and the end cover 112, and the top seal 160 is used to seal the cigarette insertion channel 123 and the cigarette insertion port 113, so that the cigarette insertion port 113 is not connected to the space inside the shell 110 outside the cigarette insertion channel 123, so that when inhaling the aerosol, it is not affected by other airflows in the shell 110.

[0057] like Figure 1 , Figure 2 and Figure 5As shown, according to some embodiments of the present application, optionally, the heating element 121 penetrates the sealing assembly 130 and the lower support platform 152 to connect the battery assembly 180, and the lower support platform 152 is provided with a hole adapted to the heating element 121, so that the heating element 121 penetrates the lower support platform 152. The lower support platform 152 is provided with a hole position corresponding to the heating element 121, and is provided with an annular seal 170 adapted to the heating element 121. The annular seal 170 has a certain degree of elasticity, so that the sealing effect is achieved by the interference fit between the annular seal 170 and the heating element 121, so that the heating element 121 penetrates the lower support platform 152 but does not affect the sealing effect. It can be understood that the function of the annular seal 170 is to seal the lower support platform 152 to prevent the lower seal 133 from being damaged when the heating component 120 is cleaned with cleaning fluid, causing the cleaning fluid to flow into between the support component 150 and the sealing component 130. At this time, the annular seal 170 can isolate the cleaning fluid inside the support component 150 and prevent it from flowing into the battery component 180 and causing damage to the battery.
