[0035] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0036] As shown in Figures 1 to 3, a baking-type atomizer device 10 according to one embodiment includes a bottom-concave heating assembly 10a based on heat-without-combustion. As shown in Figures 4 and 5, in one embodiment, the bottom-concave heating assembly 10a based on heat-without-combustion includes a heating cup 100 and a smokable substance storage bin 200. The heating cup 100 defines a hopper mounting groove 101, and at least a portion of the smokable substance storage bin 200 is accommodated within the hopper mounting groove 101. The smokable substance storage bin 200 defines a smokable substance placement groove 201 for receiving smokable substance. It is understood that the smokable substance can be tobacco paste, tobacco, herbs, or other existing smokable substances.

[0037] As shown in FIG5 , the smoking material storage bin 200 further includes an enclosure 210 and an inlay portion 220. At least a portion of the enclosure 210 is accommodated in the bin mounting groove 101. The enclosure 210 is formed with a receiving groove 211. The inlay portion 220 is concavely formed at the bottom of the enclosure 210, so that the inlay portion 220 is located within the receiving groove 211 and connected to the enclosure 210. The inlay portion 220 and the enclosure 210 are jointly limited to form a smoking material placement groove 201. In this embodiment, when a smoking material is placed in the smoking material placement groove 201, the surface of the smoking material contacts the enclosure 210, and the inlay portion 220 is embedded in the smoking material, so that the interior of the smoking material contacts the inlay portion 220. When the smoking material is baked, the heating container cup 100 generates heat, and the heat of the heating container cup 100 is transferred to the surrounding portion 210 and the embedded portion 220, so that the surrounding portion 210 heats the surface of the smoking material, and the embedded portion 220 heats the inside of the smoking material, thereby heating both the surface and the inside of the smoking material.

[0038] The above-mentioned baking-type atomization device 10 and the bottom-concave heating component 10a based on heating without burning, when baking the smoking material, the heating container cup 100 heats up, and the heat of the heating container cup 100 is transferred to the surrounding portion 210 and the embedded portion 220. Since the surrounding portion 210 is in contact with the surface of the smoking material, specifically the inner wall of the receiving groove 211 of the surrounding portion 210 is in contact with the surface of the smoking material, the surface of the smoking material is heated during baking, and since the embedded portion 220 is embedded in the interior of the smoking material, the interior of the smoking material is heated during baking. In this way, the surface and interior of the smoking material are both heated by the smoking material storage chamber 200, which increases the heating area of ​​the smoking material and improves the atomization efficiency of the smoking material.

[0039] As shown in FIG5 , in one embodiment, the heating container 100 includes an outer heating portion 110 and an inner heating portion 120. The outer heating portion 110 is formed with a receiving groove 111. The inner heating portion 120 is located in the receiving groove 111 and is connected to the outer heating portion 110. The inner heating portion 120 and the outer heating portion 110 are jointly limited to form a hopper mounting groove 101. The embedded material portion 220 is provided with a receiving groove 221. The inner heating portion 120 is located in the receiving groove 221, that is, the embedded material portion 220 is sleeved on the inner heating portion 120, which reduces the distance between the inner heating portion 120 and the embedded material portion 220, improves the heating efficiency of the inner heating portion 120 on the embedded material portion 220, that is, improves the heating efficiency of the embedded material portion 220, thereby improving the heating efficiency of the embedded material portion 220 on the inside of the smoking material and improving the atomization efficiency of the smoking material.

[0040] As shown in Figure 5 , one end of the internal heating portion 120 is in contact with the inner wall of the receiving groove 221, allowing the internal heating portion 120 to directly contact the insert portion 220, thereby improving the heat conduction efficiency of the internal heating portion 120. Furthermore, a gap exists between the peripheral wall of the internal heating portion 120 and the peripheral wall of the receiving groove 221 to improve the smoothness of the smokable material storage chamber 200.

[0041] As shown in FIG. 5 , in one embodiment, the inner heating portion 120 is concavely formed at the bottom of the outer heating portion 110 , so that the heating container cup 100 is an integrally formed structure, thereby improving the structural strength of the heating container cup 100 .

[0042] As shown in FIG5 , in one embodiment, the insert portion 220 is disposed in the middle of the surrounding portion 210, and the inner heating portion 120 is located in the middle of the outer heating portion 110. In this embodiment, because the insert portion 220 is disposed in the middle of the surrounding portion 210, when the smoking material placement slot 201 is filled with smoking material, the insert portion 220 is embedded in the middle of the smoking material, thereby improving the uniformity of heating of the smoking material, preventing local overheating of the smoking material, and preventing the smoking material from burning.

[0043] As shown in Figure 6, in one embodiment, the inner heating portion 120 has a guide surface 121 at one end adjacent to the opening of the accommodating groove 111. In this embodiment, when the smokable material accommodating bin 200 is placed into the bin mounting groove 101, the guide surface 121 can guide the inserting portion 220 into the inner heating portion 120, thereby improving the efficiency of placing the smokable material accommodating bin 200.

[0044] As shown in Figure 6, further, the guide surface 121 is an arc surface. It is understood that the guide surface 121 can also be a conical surface or other existing surfaces with a guiding function.

[0045] As shown in FIG6 , in one embodiment, the insert portion 220 is disposed in the middle of the surrounding portion 210. In this embodiment, since the insert portion 220 is disposed in the middle of the surrounding portion 210, when the smokable material placement groove 201 is filled with smokable material, the insert portion 220 is embedded in the middle of the smokable material, thereby improving the uniformity of heating of the smokable material, suppressing the problem of local overheating of the smokable material, and avoiding the problem of smokable material burning.

[0046] As shown in Figure 5, in one embodiment, a bottom clamping cavity 102 is formed between the end of the heating containing cup 100 away from the opening of the silo mounting groove 101 and the end of the smoking material containing bin 200 away from the opening of the smoking material placement groove 201. The bottom clamping cavity 102 is used to store the original gas, and an expansion gas avoidance hole 202 is provided at the end of the opening of the smoking material containing bin 200 away from the smoking material placement groove 201. The bottom clamping cavity 102 is connected to the smoking material placement groove 201 through the expansion gas avoidance hole 202. The gas in the bottom clamping cavity 102 can enter the smoking material placement groove 201 through the expansion gas avoidance hole 202 after being heated and expanded. In this embodiment, when the bottom-concave heating component 10a based on heating without burning is working, the heating accommodating cup 100 generates heat, and the heating accommodating cup 100 transfers the heat to the smoke-generating material accommodating chamber 200, so that the smoke-generating material in the smoke-generating material placement groove 201 is heated, and at the same time, the gas in the bottom clamping cavity 102 expands due to the heat, and enters the smoke-generating material placement groove 201 through the expansion gas avoidance hole 202, so that smoke is generated in the smoke-generating material placement groove 201.

[0047] As shown in FIG5 , the bottom clamping cavity 102 is further connected to the smokable material placement groove 201 via the expansion gas avoidance hole 202. The bottom clamping cavity 102 stores raw gas that can enter the smokable material placement groove 201, thereby storing raw gas that can enter the storage groove between the heating container 100 and the smokable material storage chamber 200. When the heating container 100 heats up, the raw gas expands due to the heat and immediately enters the smokable material placement groove 201 through the expansion gas avoidance hole 202. A large amount of smoke can be generated without waiting for external air to enter, thereby improving the atomization efficiency of the smokable material and increasing the amount of smoke generated per unit time.

[0048] It can be understood that the original gas is the gas stored in the bottom concave heating component 10a before the user inhales, that is, the original gas is the gas stored in the bottom concave heating component 10a before the heating accommodating cup 100 heats up.

[0049] As shown in Figures 6 and 7, in one embodiment, a gas expansion groove 103 is formed on the peripheral wall of the silo mounting groove 101. The gas expansion groove 103 is connected to the bottom clamping cavity 102. The gas expansion groove 103 is used to store raw gas. After the gas expansion groove 103 is heated and expanded, it can enter the smokable material placement groove 201 through the bottom clamping cavity 102 and the expansion gas avoidance hole 202 in sequence. In this embodiment, when the bottom concave heating component 10a based on heat without combustion is in operation, the heating cup 100 generates heat, and the heating cup 100 transfers the heat to the smokable material storage bin 200, causing the smokable material in the smokable material placement groove 201 to be heated. At the same time, the raw gas in the gas expansion groove 103 and the bottom clamping cavity 102 is heated and expanded, and enters the smokable material placement groove 201 through the expansion gas avoidance hole 202, so that the smokable material placement groove 201 produces smoke. Since both the gas expansion groove 103 and the bottom clamping cavity 102 store original gas, the original gas in the bottom concave heating component 10a based on heating without combustion is increased, the atomization efficiency is further improved, and the amount of smoke generated per unit time is further increased.

[0050] As shown in FIG6 and FIG7, in one embodiment, there are multiple gas expansion grooves 103, and the multiple gas expansion grooves 103 are arranged around the circumference of the heat containing cup 100 at intervals, so that more original gas is stored in the gas expansion grooves 103.

[0051] As shown in Figure 6, in one embodiment, the gas expansion groove 103 extends to the opening of the silo mounting groove 101, so that the gas expansion groove 103 is used to communicate with the outside, so that external air can enter from the gas expansion groove 103, ensuring that the external air replenishes the gas expansion groove 103 and the bottom clamping cavity 102 to provide original gas for the next atomization.

[0052] In one embodiment, the smokable material storage bin 200 is a metal structure, which improves the heat conduction effect of the smokable material storage bin 200 and thereby improves the efficiency of baking the smokable material in the smokable material storage bin 200. It is understood that the smokable material storage bin 200 can be an aluminum structure, a copper structure, a steel structure, or other existing metal structures.

[0053] As shown in FIG6 , in one embodiment, the bottom recessed heating assembly 10a based on heating without burning further includes two conductive pins 300, which are spaced apart and connected to the heating container 100. In this embodiment, the heating container 100 is heated by energizing the two conductive pins 300.

[0054] As shown in Figure 6, 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 of the external heating part 110, and one end of the second conductive pin 300 is connected to the inner heating part 120, so that the two conductive pins 300 are respectively connected to the inner and outer sides of the heating containing cup 100, thereby making the heating containing cup 100 heat more evenly, suppressing the problem of local overheating of the smoking material and suppressing the problem of burning of the smoking material.

[0055] In another embodiment, a bottom-recessed heating assembly 10a based on heat without combustion includes a heating element connected to a heating container 100. In this embodiment, the heating element generates heat when powered and transfers the heat to the heating container 100. It is understood that the heating element can be a heating wire, a heating sheet, a printed circuit, or other existing heating elements.

[0056] As shown in FIG5 , in one embodiment, the smoking material storage chamber 200 further includes a packaging film 230, which covers and connects to the opening of the smoking material placement groove 201 to seal the smoking material placement groove 201. In this embodiment, before the heat-not-burn bottom-recessed heating assembly 10a is used for the first time, the packaging film 230 covers the smoking material placement groove 201 to prevent the smoking material from being contaminated by external foreign matter.

[0057] As shown in FIG. 5 , in one embodiment, the smokable substance storage chamber 200 and the heating accommodating cup 100 are clearance-fitted, so that the smokable substance storage chamber 200 is easily installed in the heating accommodating cup 100 .

[0058] As shown in Figure 3, in one embodiment, the baking-type atomization device 10 also includes a support frame 10b and a fixing component 10c. The end of the heating accommodating cup 100 facing away from the silo mounting groove 101 is placed on the support frame 10b, and one end of the fixing component 10c is connected to the support frame 10b. The fixing component 10c is also sleeved on the heating accommodating cup 100 to limit the heating accommodating cup 100. The other end of the fixing component 10c abuts against the opening of the heating accommodating cup 100 to press the heating accommodating cup 100 onto the support frame 10b. In this way, the heating accommodating cup 100 is fixed to the support frame 10b by the fixing component 10c.

[0059] As shown in FIG3 , in one embodiment, the fixing assembly 10c includes a limiting sleeve 400 and a pressing member 500. The limiting sleeve 400 is connected to the support frame 10b. The limiting sleeve 400 is also sleeved on the heating accommodating cup 100 to limit the heating accommodating cup 100. An embedding groove 401 is formed between the end of the limiting sleeve 400 away from the support frame 10b and the end of the heating accommodating cup 100 away from the support frame 10b. The pressing member 500 includes an embedding portion 510 and a pressing portion 520. The embedding portion 510 is connected to the pressing portion 520. The embedding portion 510 is embedded in the embedding groove 401. One end of the pressing portion 520 abuts against the end of the heating accommodating cup 100 away from the support frame 10b, and the other end of the pressing portion 520 abuts against the end of the limiting sleeve 400 away from the support frame 10b, thereby achieving the installation of the heating accommodating cup 100.

[0060] As shown in FIG. 3 , in one embodiment, the limiting sleeve 400 and the pressing member 500 are both annular structures to improve the pressing effect on the heating accommodating cup 100 .

[0061] As shown in Figure 3, in one embodiment, the pressing portion 520 is provided with an air-supply groove 511 on the side away from the embedded portion 510, and the air-supply groove 511 extends toward the surrounding portion 210, so that the air-supply groove 511 is connected to the gap between the surrounding portion 210 and the smoke-generating material storage chamber 200, and further the air-supply groove 511 is connected to the bottom clamping cavity 102, ensuring that the external air is supplied to the bottom clamping cavity 102 through the air-supply groove 511, that is, avoiding the pressing portion 520 blocking the external air from entering the bottom clamping cavity 102, providing the original gas for the next atomization.

[0062] As shown in FIG3 , in one embodiment, an air volume expansion slot 103 is formed on the peripheral wall of the silo mounting slot 101, and the air volume expansion slot 103 is connected to the bottom clamping cavity 102. The air volume expansion slot 103 extends to the opening of the silo mounting slot 101, so that the air volume expansion slot 103 is connected to the air supply slot 511, allowing external air to directly enter the air volume expansion slot 103 through the air supply slot 511, thereby improving the efficiency of air supply.

[0063] As shown in FIG3 , the bottom recessed heating assembly 10a based on heating without burning further includes a heat insulating sleeve 600, which is sleeved on the heating accommodating cup 100 to insulate the heating accommodating cup 100. In this embodiment, the heat insulating sleeve 600 is located between the heating accommodating cup 100 and the limiting sleeve 400.

[0064] Compared with the prior art, the present disclosure has at least the following advantages:

[0065] When the smoking material is being baked, the heating container 100 generates heat, and the heat from the heating container 100 is transferred to the surrounding portion 210 and the embedded portion 220. Because the surrounding portion 210 contacts the surface of the smoking material, specifically the inner wall of the receiving groove 211 of the surrounding portion 210 contacts the surface of the smoking material, the surface of the smoking material is heated during baking. Furthermore, because the embedded portion 220 is embedded in the interior of the smoking material, the interior of the smoking material is also heated during baking. In this way, both the surface and the interior of the smoking material are heated by the smoking material container 200, increasing the heated area of ​​the smoking material and improving the atomization efficiency of the smoking material.

[0066] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
