[0033] Please see Figures 1 to 4This utility model provides an electronic atomizing device, including a mouthpiece 1, a main unit 2, and a grinding structure 3. The main unit 2 has a heating chamber 21 with one end open, and the mouthpiece 1 is detachably inserted into the heating chamber 21. The grinding structure 3 includes a grinding seat 31 disposed at the open end of the heating chamber 21 and a grinding head 32 connected to the end of the mouthpiece 1 facing the main unit 2. A connector 4 is disposed between the mouthpiece 1 and the main unit 2. The connector 4 can move relative to the mouthpiece 1 to a first position or a second position. When the connector 4 is in the first position of the mouthpiece 1, the mouthpiece 1 is fixedly connected to the main unit 2. When the connector 4 is in the second position of the mouthpiece 1, the mouthpiece 1 can drive the grinding head 32 to move relative to the grinding seat 31 to perform a grinding operation.

[0034] In this embodiment of the invention, the electronic atomizing device includes a mouthpiece 1, a main unit 2, a grinding structure 3, and a connector 4. The connector 4 and the mouthpiece 1 can have two possible connection positions: when the connector 4 is in the first position of the mouthpiece 1, the mouthpiece 1 and the main unit 2 are fixedly connected, making the positions of the mouthpiece 1 and the heating chamber 21 relatively fixed, thus forming an electronic atomizing device for heating; when the connector 4 is in the second position of the mouthpiece 1, the mouthpiece 1 can drive the grinding head 32 of the grinding structure 3 to move relative to the grinding base 31, meaning the user can perform grinding operations relative to the main unit 2 by operating the mouthpiece 1. This configuration integrates grinding and heating, allowing for on-the-go grinding and heating, making it convenient to carry and reducing operating costs; furthermore, simply adjusting the position of the connector 4 relative to the mouthpiece 1 allows for quick switching between grinding and heating, making operation convenient.

[0035] Furthermore, in some embodiments, the connector 4 is sleeved outside the suction nozzle 1 and can move axially relative to the suction nozzle 1 to a first position or a second position; the connector 4 is provided with a first limiting structure, and the suction nozzle 1 is provided with a second limiting structure, the first limiting structure and the second limiting structure cooperate to fix the connector 4 in the first position or the second position of the suction nozzle 1.

[0036] Specifically, the first limiting structure and the second limiting structure can have different connection relationships. When they are in one of the connection relationships, the connector 4 is fixed to the first position of the nozzle 1; when they are in another connection relationship, the connector 4 is fixed to the second position of the nozzle 1.

[0037] For example, the axial direction can be parallel to Figure 1 and Figure 2 The Z-axis direction in the equation.

[0038] Furthermore, one of the first limiting structure and the second limiting structure is a protrusion, and the other is a groove that mates with the protrusion.

[0039] Specifically, the protrusion can engage with the groove, and the two work together to fix the connector 4 to the nozzle 1. Furthermore, the connector 4 can be fixed at the first position and the second position of the nozzle 1 according to the specific structure of the groove.

[0040] For example, the second limiting structure may include a positioning protrusion 11 disposed on the nozzle 1 near the grinding head 32, and the positioning protrusion 11 extends axially; the first limiting structure may include a first sliding groove 41 and a second sliding groove 42 disposed on the inner side of the connector 4, the first sliding groove 41 and the second sliding groove 42 being arranged circumferentially spaced apart, wherein the axial extension dimension of the first sliding groove 41 is greater than the axial extension dimension of the second sliding groove 42; when the connector 4 is in the first position of the nozzle 1, the positioning protrusion 11 is engaged with the first sliding groove 41; when the connector 4 is in the second position of the nozzle 1, the positioning protrusion 11 is engaged with the second sliding groove 42.

[0041] Specifically, the nozzle 1 is mainly cylindrical. The outer periphery of the portion of the nozzle 1 away from the grinding head 32 has a smooth outer surface. The outer periphery of the portion of the nozzle 1 near the grinding head 32, in addition to the outer surface, also includes a positioning protrusion 11 protruding from the outer surface. The positioning protrusion 11 can extend axially to the side of the grinding head 32 facing the nozzle 1, or it can extend partially axially. The inner surface of the connector 4 is mainly adapted to the outer surface of the nozzle 1, and there can be a small gap between the inner surface of the connector 4 and the outer surface of the nozzle 1, so that the connector 4 and the nozzle 1 can rotate relative to each other when the nozzle 1 is away from the grinding head 32. At the same time, the connector 4 also has a first groove 41 and a second groove 42 that are recessed relative to each other on their inner surfaces. The axial dimension of the first groove 41 is larger than that of the second groove 42. In this way, when the positioning protrusion is in the first groove 41, the connector 4 can be closer to the grinding head 32, and ultimately the connector 4 can be connected to the host 2; when the positioning protrusion is in the second groove 42, the connector 4 cannot be connected to the host 2.

[0042] With this configuration, when the electronic atomizing device needs to be used for heating, the connector 4 can be positioned axially at the part of the nozzle 1 away from the grinding head 32. Then, the connector 4 can be rotated so that the first groove 41 of the connector 4 is aligned with the positioning protrusion 11 of the nozzle 1. Next, the connector 4 can be moved axially so that the positioning protrusion 11 passes through the first groove 41 and engages with the first groove 41, thereby achieving a fixed connection between the connector 4 and the nozzle 1. At the same time, the connector 4 is connected to the main unit 2, thus achieving a fixed connection between the nozzle 1 and the main unit 2. When grinding is required, the connector 4 can be moved axially so that the connector 4 is located at the part of the nozzle 1 away from the grinding head 32; then the connector 4 is rotated so that the second groove 42 of the connector 4 is aligned with the positioning protrusion 11 of the nozzle 1; then the connector 4 is moved axially so that the positioning protrusion 11 is engaged with the second groove 42, so that the connector 4 and the nozzle 1 are relatively fixed, and the connector 4 and the main unit 2 can be separated, so that the grinding head 32 can be moved relative to the grinding seat 31 through the nozzle 1 and the connector 4 to perform the grinding operation.

[0043] It should be noted that the first groove 41 may penetrate the top and bottom sides of the connector 4 along the axial direction, and may also include an opening and groove wall arranged opposite each other along the axial direction, wherein the opening faces the grinding head 32; while the second groove 42 includes an opening and groove wall arranged opposite each other along the axial direction, wherein the opening faces the grinding head 32.

[0044] Understandably, the second limiting structure may include a first and a second sliding groove disposed near the grinding head 32 on the nozzle 1. The first and second sliding grooves are arranged circumferentially, and the axial extension dimension of the first sliding groove is greater than that of the second sliding groove. The first limiting structure may include a positioning protrusion disposed on the inner side of the connector 4, and the positioning protrusion extends axially. Similarly, when the connector 4 is in the first position of the nozzle 1, the positioning protrusion 11 engages with the first sliding groove 41; when the connector 4 is in the second position of the nozzle 1, the positioning protrusion 11 engages with the second sliding groove 42. This also allows for quick switching between the first and second positions of the connector 4 on the nozzle 1, making the switching process convenient and fast.

[0045] Furthermore, in some specific embodiments, the connector 4 includes a cover portion 43 and a clamping portion 44 connected to the cover portion 43 and extending axially. When the connector 4 is in the first position of the nozzle 1, the cover portion 43 covers the opening of the main unit 2, and the clamping portion 44 is clamped between the main unit 2 and the nozzle 1.

[0046] Specifically, the side of the connector 4 away from the grinding head 32 is a cover part 43. The cover part 43 extends towards the grinding head 32 to form a clamping part 44. When the positioning protrusion 11 of the nozzle 1 and the first sliding groove 41 of the connector 4 are engaged, the cover part 43 of the connector 4 can cover the opening of the heating chamber 21, and the clamping part 44 is clamped between the main unit 2 and the nozzle 1. In this way, the main unit 2 can be sealed by the connector 4, so that the electronic atomizing device can be used for heating and atomizing.

[0047] In some specific embodiments, the connector 4 includes a detachably connected cover 45 and a seal 46, wherein the cover 45 has an annular groove and the seal 46 is partially disposed in the annular groove; and the cover 45 has a through hole extending vertically along the axial direction, so that the suction nozzle 1 can pass through the through hole of the cover 45; wherein a sealing portion 43 is formed in the cover 45; and the seal 46 has a sealing portion on the side away from the sealing portion 43, the sealing portion protruding from the annular groove, so that when the connector 4 is in the first position of the suction nozzle 1, the sealing portion can be clamped between the suction nozzle 1 and the main unit 2; the first sliding groove 41 and the second sliding groove 42 are mainly formed in the cover 45, and the sealing portion can have two relief grooves connecting the first sliding groove 41 and the second sliding groove 42, so that the positioning protrusion 11 can be engaged with the first sliding groove 41 or the second sliding groove 42 through the relief grooves.

[0048] Furthermore, in some specific embodiments, the grinding base 31 has a receiving groove 311 with an opening facing away from the heating cavity 21, and the grinding base 31 also has a mesh 312 that connects the heating cavity 21 and the receiving groove 311.

[0049] Specifically, the receiving groove 311 of the grinding base 31 can be used to receive solids. During the grinding operation, the positional relationship between the nozzle 1, the connector 4, and the main unit 2 can be adjusted first, and then solids such as solid flower balls can be placed into the receiving groove 311. The nozzle 1 then drives the grinding head 32 to grind the solids to form powder. The powder then passes through the mesh 312 into the heating chamber 21 for heating. In addition, when the main unit 2 is positioned so that the opening of the receiving groove 311 faces upward, after grinding, the fine powder can freely fall into the heating chamber 21 through the mesh 312, quickly filling the heating chamber 21 and ensuring grinding efficiency.

[0050] Furthermore, in some specific embodiments, the grinding seat 31 is arc-shaped and gradually narrows axially from the opening of the receiving groove 311 to the bottom of the heating chamber 21, so that the receiving groove 311 gradually narrows axially from the opening, and the grinding head 32 matches the grinding seat 31.

[0051] Specifically, the inner side of the receiving groove 311 is arc-shaped and gradually tapers from the opening to the bottom, and the outer periphery of the grinding head 32 matches the receiving groove 311. This increases the contact area between the grinding head 32 and the solid or powdery material, resulting in more thorough grinding. Furthermore, because the grinding base 31 and the grinding head 32 are arc-shaped, and there is a constant upward and downward squeezing force during the grinding process, the powdery material in the heating chamber 21 gradually accumulates through the mesh 312 as grinding progresses. Therefore, during the grinding process, the powdery material in the receiving groove 311 and the mesh 312 continuously squeeze the powdery material in the heating chamber 21, compacting it and resulting in good heat conduction and a better heating effect.

[0052] In some specific embodiments, the receiving groove 311 can be a conical groove, and the outer periphery of the grinding head 32 is also conical. In this way, when the host 2 is placed so that the opening of the receiving groove 311 faces upward, the tip of the bottom side of the grinding head 32 can first crush the solid from the middle to the periphery of the receiving groove 311. With continuous operation, the grinding head 32 and the receiving groove 311 move relative to each other so that the solid is continuously squeezed and ground.

[0053] Understandably, the receiving groove 311 and the grinding head 32 may both be hemispherical, etc. In some embodiments, the receiving groove 311 and the grinding head 32 may also have mismatched shapes. For example, the receiving groove 311 may be arc-shaped, and the grinding head 32 may be rod-shaped.

[0054] Furthermore, in some specific embodiments, the grinding head 32 is provided with a plurality of spaced protrusions 321 on the side facing the receiving groove 311.

[0055] Specifically, the outer periphery of the grinding head 32 can also be provided with multiple protrusions 321. In this way, during grinding, the solid in the receiving groove 311 can be continuously crushed by the protrusions 321 on the outer periphery of the grinding head 32, and finally formed into powder. This can speed up the grinding rate and further improve the grinding effect.

[0056] Furthermore, in some specific embodiments, the distribution of the multiple protrusions 321 is adapted to the arrangement of the mesh 312. Thus, as the grinding proceeds, the powdery material in the heating chamber 21 will gradually accumulate through the mesh 312. Moreover, there is always an upward and downward squeezing force during the grinding process. This allows the powdery material in the heating chamber 21 to be continuously squeezed through the through holes via the protrusions 321, thereby better compacting the powdery material in the heating chamber 21. This results in good heat conduction during heating and achieves a better heating effect.

[0057] Understandably, the shape of the protrusion 321 is not limited; for example, it may be conical or hemispherical, etc.

[0058] Furthermore, in some specific embodiments, the host 2 has an air inlet 22 that communicates with the heating chamber 21, and when the connector 4 is in the first position of the nozzle 1, there is a gap between the grinding seat 31 and the grinding head 32 that communicates with the mesh 312.

[0059] Specifically, the main unit 2 is provided with an air inlet 22 that connects to the outside and the heating chamber 21. When the connector 4 is in the first position of the nozzle 1, there is a gap between the grinding seat 31 and the grinding head 32 located at the opening of the heating chamber 21. The gap connects to the mesh 312. Therefore, when the electronic atomizing device is used for heating, the external airflow can flow through the air inlet 22 to the heating chamber 21, and then drive the atomized gas in the heating chamber 21 to flow through the mesh 312 to the gap.

[0060] Furthermore, in some specific embodiments, the nozzle 1 has a communicating gap and an external air outlet channel 12.

[0061] Specifically, the mouthpiece 1 includes a main body and a base 13. The main body has a positioning protrusion 11 on its outer side for switching between heating and grinding functions of the electronic atomizing device. An air outlet channel 12 is provided on the inner side of the main body, communicating with a gap. The base 13 is connected to the grinding head 32, thus fixing the grinding head 32 and the base 13 relatively together. When the electronic atomizing device is used for heating, external airflow can flow through the air inlet 22 to the heating chamber 21, then drive the atomized gas in the heating chamber 21 through the mesh 312 to the gap, and then through the gap to the air outlet channel 12.

[0062] Furthermore, in some specific embodiments, the electronic atomizing device also includes a filter screen 5, which is disposed between the mouthpiece 1 and the grinding head 32 so that the airflow flows through the gap through the filter screen 5 and then flows to the air outlet channel 12.

[0063] Specifically, a filter screen 5 can be connected between the nozzle 1 and the grinding head 32. Thus, when the electronic atomizing device is used for heating, external airflow can flow through the air inlet 22 to the heating chamber 21, then drive the atomized gas in the heating chamber 21 through the mesh 312 to the gap, then through the gap to the filter screen 5, and finally through the filter screen 5 to the air outlet channel 12. The filter screen 5 can filter dust from the air passage.

[0064] Furthermore, in some specific embodiments, the mouthpiece 1 includes a base 13, and the electronic atomizing device also includes an air passage 6 detachably connected to the base 13. The assembly space formed by the base 13 and the air passage 6 is provided with an air passage hole that connects the gap and the air outlet 12. Thus, when the electronic atomizing device is used for heating, the external airflow can flow through the air inlet 22 to the heating chamber 21, and then drive the atomized gas in the heating chamber 21 to flow through the mesh 312 to the gap, and then through the gap to the air passage hole, so as to flow to the filter screen 5, and finally through the air passage hole to the air outlet 12.

[0065] Furthermore, in some embodiments, the grinding head 32 is detachably connected to the nozzle 1; and / or, the grinding seat 31 is detachably connected to the opening of the heating chamber 21.

[0066] For example, the base 13 of the nozzle 1 can be connected to the grinding head 32 via a snap-fit ​​structure. The grinding seat 31 can also be connected to the opening of the heating chamber 21 via a snap-fit ​​structure. This configuration allows for easy replacement of the worn-out grinding head 32 and grinding seat 31 after grinding.

[0067] Furthermore, in some specific embodiments, the outer periphery of the connector 4 is provided with an anti-slip structure 47.

[0068] For example, the anti-slip structure 47 can be a pleated structure, etc., which can not affect the connection 4 being clamped between the nozzle 1 and the main unit 2, and can also increase the friction between the user and the connection 4, thereby making it easier for the user to perform grinding operations.

[0069] In some specific embodiments, the connector 4 includes a cover 45 and a seal 46. The seal 46 is disposed in the annular groove of the cover 45. The main body of the nozzle 1 passes through the through hole of the cover 45. The anti-slip structure 47 can be disposed on the outer periphery of the cover 45. This does not affect the cover 45 being clamped between the nozzle 1 and the main unit 2. It can also increase the friction between the user and the cover 45, thereby facilitating the user to perform grinding operations.

[0070] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0071] The above is a description of the technical solution provided by this utility model. For those skilled in the art, based on the idea of ​​the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
