Specific Implementation To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0012] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0013] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of some inventions, "a plurality of" means two or more, unless otherwise explicitly specified.

[0015] This invention provides a heating mechanism for heating and baking a target substance to produce smoke, which can be inhaled by a user. For example, in possible embodiments, the target substance may be tobacco or the like.

[0016] See Figure 1 The heating mechanism includes a heating element 100 and a hopper assembly 200. The hopper assembly 200 is used to store the target substance, and the heating element 100 heats and bakes the target substance in the hopper assembly 200, causing the target substance to produce smoke.

[0017] See Figure 2 The heating assembly 100 includes a heating control structure 110 and a heating element 120. The heating element 120 is connected to the heating control structure 110 and extends in a direction away from the heating control structure 110. The heating element 120 may extend in a direction away from the heating control structure 110 to protrude from the heating control structure 110. For example, the heating element 120 may extend to form a "columnar" or "needle-like" structure so that the heating element 120 can subsequently act on the hopper assembly 200 to heat the target material.

[0018] The heating control structure 110 is used to control the heating element 120 to generate heat. For example, the heating element 120 can be made of carbon-based materials, metal materials, functional ceramic materials, etc. These materials can generate heat when current flows through the heating control structure 110, thereby controlling whether the heating element 120 generates heat.

[0019] Furthermore, the combination of the heating control structure 110 and the heating element facilitates the control of the heating element's temperature changes through the heating control structure 110. For example, by controlling the magnitude of the current flowing through the heating element, the temperature change of the heating element can be controlled, thereby enabling the selection of a suitable temperature for heating or baking the target material. For instance, the heating control structure 110 can dynamically control the heating temperature of the heating element to achieve dynamic heating and baking of the target material, and the smoke generated by the target material can achieve the desired effect.

[0020] See Figure 3 The hopper assembly 200 may include a hopper body 210, which has an open storage cavity 220 for storing target materials. For example, target materials that have not been heated or baked can be placed into the storage cavity 220, and target materials that have been heated or baked can be poured out of the storage cavity 220.

[0021] Furthermore, when it is necessary to heat the target material, the chamber 210 can be connected to one end of the heating element 120 of the heating control structure 110 through the opening of the storage cavity 220. During the connection between the chamber 210 and the heating control structure 110, the heating element 120 can be inserted into the storage cavity 220 of the chamber 210 to heat the target material. During the heating process, the target material can be baked.

[0022] In the heating mechanism of the present invention, the heating element 120 of the heating assembly 100 is disposed at one end of the heating control structure 110 and extends away from the heating control structure 110. The heating control structure 110 controls the heating element 120 to heat up. The hopper assembly 200 has a storage cavity 220 with an opening, which is used to store the target material. The opening of the storage cavity 220 is used to connect the hopper 210 to the end of the heating control structure 110 that is connected to the heating element 120. When connected, the heating element 120 can be inserted into the storage cavity 220. The heating control structure 110 can control the heating element 120 to heat and bake the target material. This method can realize the heating and baking of the target material, and the heating and baking temperature can be easily controlled by the heating control structure 110. The heating and baking temperature can be adjusted and set according to different target materials and user preferences.

[0023] See Figure 1 In one embodiment, the chamber body 210 and the heating control structure 110 can be connected by a threaded connection, or the chamber body 210 and the heating control structure 110 can be connected by having a retaining groove 250 on one of them (the retaining groove 250 can be an "L" shaped groove) and a retaining block 140 on the other. During connection, the retaining block 140 is held in the "L" shaped groove by inserting and rotating it. Of course, there are many other ways to fix the chamber body 210 and the heating control structure 110 after they are connected, such as snap-fit ​​structures, which will not be described in detail here.

[0024] In one embodiment, the heating control structure 110 may include a power source such as a battery or a PCB control board. The power source can supply power to the PCB control board, and the PCB control board can control the temperature change of the heating element to make the heating element heat up at the expected temperature.

[0025] In one embodiment, when the storage chamber 210 is connected to one end of the heating element 120 of the heating control structure 110 through the opening of the storage cavity 220, the heating element 120 is configured to be inserted into the target material and to make at least a portion of the heating element in contact with the target material. For example, the heating element inserted into the target material may be in complete contact with the target material, or the heating element inserted into the target material may be in partial contact with the target material.

[0026] Optionally, see Figures 7a to 7g The heating element 120 can be a "columnar" or "needle" structure. The side of the heating element can be a regular plane or arc surface. The side of the heating element can be uniformly extended or stepped in a graded manner. The side of the heating element can be spirally extended and twisted, etc.

[0027] See Figure 4In one embodiment, when the heating element 120 is inserted into the storage cavity 220, a first gap 440a is formed between the heating element 120 and the cavity wall of the storage cavity 220, and part of the target material is squeezed into the first gap 440a by the heating element 120. This method allows the heating element 120 to compress or squeeze the target material when inserted into the storage cavity 220, while the first gap 440a provides space for the compressed or squeezed target material. The size of the first gap 440a can be set according to actual needs. When the first gap 440a is larger, the degree of compression or squeezing of the target material by the heating element 120 is lower; when the first gap 440a is smaller, the degree of compression or squeezing of the target material by the heating element 120 is higher. The degree of compression or squeezing of the target material by the heating element 120 results in different degrees of heating and baking of the target material. Specifically, it can be set according to needs, for example, by adjusting the diameter or width of the heating element 120.

[0028] In one embodiment, when the heating element 120 is inserted into the storage cavity 220, a second gap 440b is formed between the heating element 120 and the bottom of the storage cavity 220, and part of the target material is squeezed into the second gap 440b by the heating element 120. The size of the second gap 440b can be set according to actual needs. When the second gap 440b is larger, the degree of squeezing or compression of the target material by the heating element 120 is lower; when the second gap 440b is smaller, the degree of squeezing or compression of the target material by the heating element 120 is higher. The degree of squeezing or compression of the target material by the heating element 120 results in different degrees of heating and baking of the target material by the heating element 120. Specifically, it can be set according to needs, for example, by adjusting the axial length of the heating element 120.

[0029] Combination Figure 1 and Figure 4 The central axis of the heating element 120 and the central axis of the opening of the storage cavity 220 are located on the same axis, that is, the heating element 120 and the opening of the storage cavity 220 are coaxial. In one embodiment, when the chamber body 210 and the heating control structure 110 are connected and fixed by rotation, interference from the heating element 120 during rotation is avoided.

[0030] Optionally, the opening of the storage chamber 220 is coaxial with the storage chamber 220.

[0031] See Figure 1 , Figure 2 , Figures 7a to 7gThe area of ​​the cross-section of the heating element 120, at least at the end furthest from the heating control structure 110, gradually decreases, and the cross-section is perpendicular to the central axis of the heating element 120. It can be understood that this method reduces the contact area between the end of the heating element 120 furthest from the heating control structure 110 and the target material, which is beneficial for the heating element 120 to be inserted into the target material.

[0032] For example, at least one end of the heating element 120 furthest from the heating control structure 110 can be made into a conical surface. It should be noted that the outer surface of the conical surface can be a circular arc or a prismatic bevel, etc., which can be selected according to the requirements.

[0033] In one embodiment, the target substance can be stored in the container 300 for convenient storage and replacement.

[0034] Specifically, see Figure 5 and Figure 6 The container 300 includes a receiving cavity 310. The target substance is stored in the receiving cavity 310. One end of the container 300 is respectively provided with a first through hole 320 and a second through hole 330 communicating with the receiving cavity 310. The container 300 is configured to be installed in the storage cavity 220 through the opening of the storage cavity 220, and when the hopper 210 is sleeved with the heating control structure 110, the end of the container 300 provided with the first through hole 320 and the second through hole 330 faces the heating control structure 110, so that the heating element 120 can be inserted into the receiving cavity 310 through the first through hole 320 to heat the target substance, and the smoke generated by heating the target substance can flow out of the receiving cavity 310 through the second through hole 330.

[0035] In one embodiment, the container 300 can be made of wood or bamboo, which are environmentally friendly and readily available. Once the target material inside the container cavity 310 has been heated and baked, the entire container 300 can be discarded directly.

[0036] Further, see Figure 5 When the target material is stored in the container 300, the heating element 120 can be configured to form a third gap 440c between the heating element 120 and the cavity wall of the container 310 when it is inserted into the storage cavity 220, and part of the target material is squeezed into the third gap 440c by the heating element 120.

[0037] When the target material is stored in the container 300, the heating element 120 is set to be inserted into the storage cavity 220, and a fourth gap 400d is formed between the heating element 120 and the bottom of the container 310, and part of the target material is squeezed into the fourth gap 400d by the heating element 120.

[0038] In one embodiment, in order to facilitate the accurate insertion of the heating element 120 into the receiving cavity 310, the central axis of the first through hole 320 is located on the same axis as the central axis of the heating element.

[0039] For example, when the container 300 is installed into the storage cavity 220, the central axis of the first through hole 320 provided on the container 300 can be exactly on the same axis as the central axis of the opening of the storage cavity 220. Therefore, when the hopper 210 is sleeved with the temperature control structure, the central axis of the first through hole 320 can be exactly on the same axis as the central axis of the heating element.

[0040] Optionally, the storage cavity 220 may be provided with a positioning structure for positioning the container 300, or the shape and size of the storage cavity 220 may be adapted to the container 300. For example, the storage cavity 220 may be configured as a flared structure. When the container 300 is installed in the storage cavity 220, the end of the storage cavity 220 away from the opening may be clamped and fixed to the outer peripheral surface of the container 300, so that when the container 300 is installed in the storage cavity 220, the central axis of the first through hole 320 provided on the container 300 may be exactly on the same axis as the central axis of the opening of the storage cavity 220.

[0041] See Figure 6 In one embodiment, the heating component 100 may further include a kit 130, which is connected to the heating control structure 110. The heating element 120 is located inside the kit 130. When the housing 210 is sleeved with the heating control structure 110, the kit 130 sleeves and limits the receiving body 300, which helps to ensure that the heating element can be accurately inserted into the first through hole 320.

[0042] For example, the first through hole 320, the container 300 and the receiving cavity 310 are on the same axis, and the kit 130 can be coaxial with the heating element. When the kit 130 is sleeved with the container 300, the kit 130 and the container 300 are coaxial. This method can facilitate the accurate insertion of the heating element into the first through hole 320.

[0043] See Figure 4 or Figure 5The hopper assembly 200 may also include a button 230, which is movably disposed at the end of the hopper body 210 away from the heating control structure 110. When the container 300 is installed in the storage cavity 220, the button 230 abuts against the end of the container 300 away from the heating control structure 110. During the process of the hopper body 210 and the heating control structure 110 being fitted together, the heating control structure 110 abuts against the end of the container 300 away from the button 230 and restricts the movement of the container 300. At the same time, the button 230 can be actuated by the container 300 to protrude from the end face of the hopper body 210 away from the heating control structure 110. Understandably, when the chamber 210 containing the container 300 is connected to the temperature control structure, the button 230 can protrude from the end face of the chamber 210 away from the heating control structure 110 under the action of the container 300. Therefore, if it is necessary to replace the container 300, after separating the chamber 210 from the temperature control structure, the button 230 can be pressed to squeeze the container 300 out of the receiving cavity 310 a certain distance, making it convenient to remove the container 300 and replace the container 300.

[0044] For example, in one embodiment, button 230 is configured to move a preset distance along the central axis of storage cavity 220 on the hopper 210. The length of the container 300 is set to a first preset length, and the length of storage cavity 220 is set to a second preset length. The sum of the preset distance and the second preset length is greater than the first preset length, and the difference between the preset distance and the second preset length is less than the first preset length. This arrangement allows the container 300 to be completely contained within storage cavity 220, enabling storage cavity 220 to be fitted with the temperature control structure after the container 300 is installed, avoiding interference from the container 300. Furthermore, when the container 300 needs to be replaced, pressing button 230 moves the container 300, allowing the end of the container 300 away from button 230 to protrude from storage cavity 220, facilitating replacement of the container 300.

[0045] Specifically, in one embodiment, see [reference] Figure 4 A limiting groove 260 can be provided on the outer peripheral surface of the button 230. The button 230 is held on the compartment 210 by the limiting groove 260. The length of the limiting groove 260 along the axial direction parallel to the button 230 is equal to the preset moving distance, so that the button 230 can move relative to the compartment 210 under the action of the limiting groove 260. At the same time, the groove walls at both ends of the limiting groove 260 along the axial direction parallel to the button 230 can stop the compartment 210 to prevent the button 230 from falling off the compartment 210.

[0046] See Figure 5In one embodiment, the end of the container 300 away from the first through hole 320 may also be provided with a feed inlet 340 communicating with the receiving cavity 310. When the container 300 is installed in the storage cavity 220, the feed inlet 340 can be blocked by the button 230. It should be noted that the feed inlet 340 can be partially blocked by the button 230. For example, the button 230 may be provided with an air inlet 240, which can communicate with the feed inlet 340. In this case, the area where the air inlet is located on the button 230 does not block the feed inlet 340.

[0047] See Figure 8 and Figure 9 This application also provides an inhalation device, including a mouthpiece 500 and a heating mechanism according to the embodiments of this application. The mouthpiece 500 is connected to the end of the heating control structure 110 away from the heating element 120. The heating control structure 110 is provided with an airway. One end of the airway is connected to the storage chamber 220, and the other end of the airway is connected to the mouthpiece 500.

[0048] Specifically, the heating control structure 110 controls the heating element 120 to heat up and bake the target material, and the resulting smoke can be inhaled by the user through the storage chamber 220, the air passage and the mouthpiece 500.

[0049] Furthermore, in one embodiment, the target substance is contained in the containment cavity 310 of the containment body 300, and a first through hole 320 and a second through hole 330 communicating with the containment cavity 310 are respectively provided at one end of the containment body 300.

[0050] The container 300 is configured to be installed in the storage cavity 220 through the opening of the storage cavity 220. When the container body 210 is sleeved with the heating control structure 110, one end of the container 300 with the first through hole 320 and the second through hole 330 faces the heating control structure 110, so that the heating element 120 can be inserted into the container cavity 310 through the first through hole 320 to heat the target substance. The smoke generated by heating the target substance can flow out of the container cavity 310 into the storage cavity 220 through the second through hole 330. The smoke in the storage cavity 220 is inhaled by the user in sequence through the air passage and the mouthpiece 500.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the invention should be included within the protection scope of the invention.
