The terms used in the description of the present disclosure in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0035] As Figures 1 to 3 shown, a baking atomization device 10 of an embodiment includes a bottom concave heating component 10a based on heat-not-burn. As Figure 4 and Figure 5 shown, in one of the embodiments, the bottom concave heating component 10a based on heat-not-burn includes a heating accommodation cup 100 and a smokeable material accommodation bin 200. The heating accommodation cup 100 is provided with a bin installation groove 101. At least a part of the smokeable material accommodation bin 200 is accommodated in the bin installation groove 101. The smokeable material accommodation bin 200 is provided with a smokeable material placement groove 201 for accommodating the smokeable material. It can be understood that the smokeable material can be a smoke paste, tobacco, herbs or other existing smokeable materials.

[0036] As Figure 5As shown in the figure, further, the smoke generating material accommodating bin 200 includes an enclosing part 210 and an insert part 220. At least part of the enclosing part 210 is accommodated in the bin installation groove 101. A receiving groove 211 is formed in the enclosing part 210. The insert part 220 is recessed and formed at the bottom of the enclosing part 210, so that the insert part 220 is located in the receiving groove 211 and connected to the enclosing part 210. The insert part 220 and the enclosing part 210 jointly limit and form a smoke generating material placement groove 201. In this embodiment, when the smoke generating material is placed in the smoke generating material placement groove 201, the surface of the smoke generating material contacts the enclosing part 210, and the insert part 220 is embedded inside the smoke generating material, so that the inside of the smoke generating material contacts the insert part 220. When baking the smoke generating material, the heating accommodating cup 100 generates heat, and the heat of the heating accommodating cup 100 is conducted to the enclosing part 210 and the insert part 220, so that the enclosing part 210 heats the surface of the smoke generating material, and the insert part 220 heats the inside of the smoke generating material, thereby heating both the surface and the inside of the smoke generating material.

[0037] For the above-mentioned baking type atomizing device 10 and the bottom concave type heating component 10a based on heat-not-burn, when baking the smoke generating material, the heating accommodating cup 100 generates heat, and the heat of the heating accommodating cup 100 is conducted to the enclosing part 210 and the insert part 220. Since the enclosing part 210 contacts the surface of the smoke generating material, specifically, the inner wall of the receiving groove 211 of the enclosing part 210 contacts the surface of the smoke generating material, the surface of the smoke generating material is heated during baking. Also, since the insert part 220 is embedded inside the smoke generating material, the inside of the smoke generating material is heated during baking. In this way, both the surface and the inside of the smoke generating material are heated by the smoke generating material accommodating bin 200, increasing the heating area of the smoke generating material and improving the atomizing efficiency of the smoke generating material.

[0038] As Figure 5 shown, in one embodiment, the heating accommodating cup 100 includes an outer heating part 110 and an inner heating part 120. A receiving groove 111 is formed in the outer heating part 110. The inner heating part 120 is located in the receiving groove 111 and connected to the outer heating part 110. The inner heating part 120 and the outer heating part 110 jointly limit and form a bin installation groove 101. The insert part 220 is provided with a receiving groove 221, and the inner heating part 120 is located in the receiving groove 221, that is, the insert part 220 is sleeved on the inner heating part 120, reducing the distance between the inner heating part 120 and the insert part 220, improving the heating efficiency of the inner heating part 120 on the insert part 220, that is, improving the heating efficiency of the insert part 220 to increase the temperature, and further improving the heating efficiency of the insert part 220 on the inside of the smoke generating material and the atomizing efficiency of the smoke generating material.

[0039] As Figure 5As shown, further, one end of the inner heating part 120 contacts the inner wall of the receiving groove 221, so that the inner heating part 120 is in direct contact with the embedded material part 220, improving the heat conduction efficiency of the inner heating part 120. Further, there is a gap between the peripheral wall of the inner heating part 120 and the peripheral wall of the receiving groove 221 to improve the smoothness of the smoke-emitting material accommodating chamber 200.

[0040] As Figure 5 shown, in one embodiment, the inner heating part 120 is recessed at the bottom of the outer heating part 110, so that the heat-receiving cup 100 is an integrally formed structure, improving the structural strength of the heat-receiving cup 100.

[0041] As Figure 5 shown, in one embodiment, the embedded material part 220 is arranged at the middle of the surrounding part 210, and the inner heating part 120 is located at the middle of the outer heating part 110. In this embodiment, since the embedded material part 220 is arranged at the middle of the surrounding part 210, when the smoke-emitting material fills the smoke-emitting material placement groove 201, the embedded material part 220 is embedded in the middle of the smoke-emitting material, improving the uniformity of heat reception of the smoke-emitting material, suppressing the problem of local overheating of the smoke-emitting material, and suppressing the problem of the smoke-emitting material being charred.

[0042] As Figure 6 shown, in one embodiment, one end of the inner heating part 120 adjacent to the opening of the accommodating groove 111 has a guiding surface 121. In this embodiment, during the process of placing the smoke-emitting material accommodating chamber 200 into the magazine installation groove 101, the guiding surface 121 can guide the embedded material part 220 to be sleeved on the inner heating part 120, improving the efficiency of placing the smoke-emitting material accommodating chamber 200.

[0043] As Figure 6 shown, further, the guiding surface 121 is an arc surface. It can be understood that the guiding surface 121 can also be a conical surface or other existing surfaces with guiding functions.

[0044] As Figure 6 shown, in one embodiment, the embedded material part 220 is arranged at the middle of the surrounding part 210. In this embodiment, since the embedded material part 220 is arranged at the middle of the surrounding part 210, when the smoke-emitting material fills the smoke-emitting material placement groove 201, the embedded material part 220 is embedded in the middle of the smoke-emitting material, improving the uniformity of heat reception of the smoke-emitting material, suppressing the problem of local overheating of the smoke-emitting material, and avoiding the problem of the smoke-emitting material being charred.

[0045] As Figure 5As shown, in one of the embodiments, a bottom clamping cavity 102 is formed between one end of the heat-generating accommodating cup 100 facing away from the opening of the material bin installation groove 101 and one end of the smoke-generating material accommodating bin 200 facing away from the opening of the smoke-generating material placement groove 201. The bottom clamping cavity 102 is used to store the original gas. An expansion gas avoidance hole 202 is provided at one end of the smoke-generating material accommodating bin 200 facing away from the opening of the smoke-generating material placement groove 201. The bottom clamping cavity 102 is communicated with the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202. The gas in the bottom clamping cavity 102 can enter the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202 after being heated and expanded. In this embodiment, when the bottom concave type heating component 10a based on heat-not-burn works, the heat-generating accommodating cup 100 generates heat. The heat-generating accommodating cup 100 conducts the heat to the smoke-generating material accommodating bin 200, so that the smoke-generating material in the smoke-generating material placement groove 201 is heated. At the same time, the gas in the bottom clamping cavity 102 is heated and expanded and enters the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202, so that smoke can be generated in the smoke-generating material placement groove 201.

[0046] As Figure 5 shown, further, the bottom clamping cavity 102 is communicated with the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202. The bottom clamping cavity 102 stores the original gas that can enter the smoke-generating material placement groove 201. Furthermore, the original gas that can enter the containing groove is stored between the heat-generating accommodating cup 100 and the smoke-generating material accommodating bin 200. When the heat-generating accommodating cup 100 generates heat, the original gas is heated and expanded and immediately enters the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202. Larger smoke can be generated without waiting for external air to enter, which improves the atomization efficiency of the smoke-generating material and also makes the amount of smoke generated per unit time larger.

[0047] It can be understood that the original gas is the gas stored by the bottom concave type heating component 10a before the user sucks. That is, the original gas is the gas stored by the bottom concave type heating component 10a before the heat-generating accommodating cup 100 generates heat.

[0048] As Figure 6 and Figure 7As shown, in one embodiment, an air volume expansion groove 103 is formed on the peripheral wall of the bin installation groove 101. The air volume expansion groove 103 is communicated with the bottom clamping cavity 102. The air volume expansion groove 103 is used to store the original gas. After being heated and expanded, the air volume expansion groove 103 can sequentially enter the smoke generating agent placement groove 201 through the bottom clamping cavity 102 and the expansion gas avoidance hole 202. In this embodiment, when the bottom concave heating component 10a based on heat-not-burn works, the heat generating accommodating cup 100 generates heat. The heat generating accommodating cup 100 conducts the heat to the smoke generating agent accommodating bin 200, so that the smoke generating agent in the smoke generating agent placement groove 201 is heated. At the same time, the original gas in the air volume expansion groove 103 and the bottom clamping cavity 102 is heated and expanded, and enters the smoke generating agent placement groove 201 through the expansion gas avoidance hole 202, so that smoke can be generated in the smoke generating agent placement groove 201. Since both the air volume expansion groove 103 and the bottom clamping cavity 102 store the original gas, the original gas in the bottom concave heating component 10a based on heat-not-burn is increased, the atomization efficiency is further improved, and the amount of smoke generated per unit time is further increased.

[0049] As Figure 6 and Figure 7 shown, in one embodiment, the number of the air volume expansion grooves 103 is multiple. The multiple air volume expansion grooves 103 are arranged at intervals along the circumferential direction of the heat generating accommodating cup 100, so that more original gas is stored in the air volume expansion grooves 103.

[0050] As Figure 6 shown, in one embodiment, the air volume expansion groove 103 extends to the opening of the bin installation groove 101, so that the air volume expansion groove 103 is used to communicate with the outside, so that external air can enter from the air volume expansion groove 103, ensuring that the external air supplements air to the air volume expansion groove 103 and the bottom clamping cavity 102, and providing the original gas for the next atomization.

[0051] In one embodiment, the smoke generating agent accommodating bin 200 is made of a metal structure, so that the heat conduction effect of the smoke generating agent accommodating bin 200 is better, and thus the baking efficiency of the smoke generating agent accommodating bin 200 for the smoke generating agent is improved. It can be understood that the smoke generating agent accommodating bin 200 can be an aluminum structure, a copper structure, a steel structure or other existing metal structures.

[0052] As Figure 6 shown, in one embodiment, the bottom concave heating component 10a based on heat-not-burn further includes two conductive pins 300. The two conductive pins 300 are connected to the heat generating accommodating cup 100 at intervals. In this embodiment, the heat generating accommodating cup 100 is heated by energizing the two conductive pins 300.

[0053] As Figure 6As shown, further, the two conductive pins 300 are respectively a first conductive pin 300 and a second conductive pin 300. One end of the first conductive pin 300 is connected to the outer side surface of the outer heating part 110, and one end of the second conductive pin 300 is connected to the inner heating part 120, such that the two conductive pins 300 are respectively connected to the inside and the outer side surface of the heating receiving cup 100. Furthermore, the heating receiving cup 100 heats more uniformly, suppressing the problem of local overheating of the smoking material and the problem of the smoking material being scorched.

[0054] In another embodiment, the bottom concave heating assembly 10a for heat-not-burn includes a heating element, and the heating element is connected to the heating receiving cup 100. In this embodiment, the heating element is energized to generate heat and conducts the heat to the heating receiving cup 100. It can be understood that the heating element can be a heating wire, a heating sheet, a printed circuit, or other existing heating elements.

[0055] As Figure 5 shown, in one of the embodiments, the smoking material receiving chamber 200 further includes a packaging film 230, and the packaging film 230 is hermetically connected to the opening of the smoking material placement groove 201 to enclose the smoking material placement groove 201. In this embodiment, before the bottom concave heating assembly 10a for heat-not-burn is used for the first time, the packaging film 230 covers the smoking material placement groove 201, avoiding the problem of external foreign objects contaminating the smoking material.

[0056] As Figure 5 shown, in one of the embodiments, the smoking material receiving chamber 200 and the heating receiving cup 100 are in clearance fit, such that the smoking material receiving chamber 200 is relatively easy to be installed on the heating receiving cup 100.

[0057] As Figure 3 shown, in one of the embodiments, the baking atomization device 10 further includes a support frame 10b and a fixing assembly 10c. One end of the heating receiving cup 100 facing away from the material bin installation groove 101 is placed on the support frame 10b. One end of the fixing assembly 10c is connected to the support frame 10b, and the fixing assembly 10c also sleeved on the heating receiving cup 100 to limit the heating receiving cup 100. The other end of the fixing assembly 10c abuts against the opening of the heating receiving cup 100 to press the heating receiving cup 100 against the support frame 10b. In this way, the heating receiving cup 100 is fixed on the support frame 10b by the fixing assembly 10c.

[0058] As Figure 3As shown, in one embodiment, the fixing component 10c includes a limiting sleeve 400 and a pressing component 500. The limiting sleeve 400 is connected to the support frame 10b, and the limiting sleeve 400 also sleeved on the heating receiving cup 100 to limit the heating receiving cup 100. An embedding groove 401 is formed between one end of the limiting sleeve 400 facing away from the support frame 10b and one end of the heating receiving cup 100 facing away from the support frame 10b. The pressing component 500 includes an embedding part 510 and a pressing part 520. The embedding part 510 is connected to the pressing part 520. The embedding part 510 is embedded in the embedding groove 401. One end of the pressing part 520 abuts against one end of the heating receiving cup 100 facing away from the support frame 10b, and the other end of the pressing part 520 abuts against one end of the limiting sleeve 400 facing away from the support frame 10b, thus realizing the installation of the heating receiving cup 100.

[0059] As Figure 3 shown, in one embodiment, both the limiting sleeve 400 and the pressing component 500 are annular structures to improve the pressing effect on the heating receiving cup 100.

[0060] As Figure 3 shown, in one embodiment, an air supplement through groove 511 is formed on one side of the pressing part 520 facing away from the embedding part 510. The air supplement through groove 511 extends towards the surrounding part 210, so that the air supplement through groove 511 is communicated with the gap between the surrounding part 210 and the smoke generating agent receiving bin 200, and further the air supplement through groove 511 is communicated with the bottom clamping cavity 102, ensuring that external air supplements the bottom clamping cavity 102 through the air supplement through groove 511, that is, preventing the pressing part 520 from hindering the external air from entering the bottom clamping cavity 102 and providing the original gas for the next atomization.

[0061] As Figure 3 shown, in one embodiment, an air volume expansion groove 103 is formed on the peripheral wall of the material bin installation groove 101. The air volume expansion groove 103 is communicated with the bottom clamping cavity 102. The air volume expansion groove 103 extends to the opening of the material bin installation groove 101, so that the air volume expansion groove 103 is communicated with the air supplement through groove 511, enabling external air to directly enter the air volume expansion groove 103 through the air supplement through groove 511 and improving the efficiency of air supplement.

[0062] As Figure 3 shown, further, the bottom concave type heating component 10a based on heat-not-burn further includes a heat insulation sleeve 600. The heat insulation sleeve 600 is sleeved on the heating receiving cup 100 to insulate the heating receiving cup 100. In this embodiment, the heat insulation sleeve 600 is located between the heating receiving cup 100 and the limiting sleeve 400.

[0063] Compared with the prior art, the present disclosure has at least the following advantages:

[0064] When baking the smoking material, the heat-containing cup 100 generates heat, and the heat of the heat-containing cup 100 is conducted to the surrounding part 210 and the embedding part 220. Since the surrounding part 210 is in contact with the surface of the smoking material, specifically, the inner wall of the receiving groove 211 of the surrounding part 210 is in contact with the surface of the smoking material, the surface of the smoking material is heated during baking. Also, since the embedding part 220 is embedded inside the smoking material, the inside of the smoking material is heated during baking. Thus, both the surface and the inside of the smoking material are heated by the smoking material accommodating chamber 200, increasing the heating area of the smoking material and improving the atomization efficiency of the smoking material.

[0065] The above-described embodiments merely represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
