Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an atomizer and electronic atomization device. Background Technology

[0002] Electronic cigarettes and electronic devices used to atomize health care drugs, therapeutic drugs and other substances can be collectively referred to as electronic atomization devices. Currently, most electronic atomization devices on the market generally include an atomizer for generating aerosol and a battery pack for powering the atomizer. As the core component of electronic atomization devices, the atomizer has always been a research focus for those skilled in the art.

[0003] In related technologies, there are some atomizer structures, including a liquid reservoir, an airflow channel, and an atomizing core located in the airflow channel. The airflow channel is located outside the liquid reservoir and is in communication with the outside. The liquid reservoir is pre-filled with atomizing liquid (such as e-liquid), and the atomizing core is in communication with the liquid reservoir.

[0004] However, atomizers with this type of structure generally have the following problems:

[0005] Because the reservoir cup and the atomizer coil are always connected, when the atomizer is not in use (e.g., when the atomizer is in transport or not in a vaping state), the atomized liquid in the reservoir cup may leak from the atomizer coil into the airflow channel, and then leak from the airflow channel to the outside. This leakage problem is more likely to occur when the atomizer is in a non-use state such as high-altitude transport, low temperature, or low pressure. Utility Model Content

[0006] The purpose of this utility model is to provide an atomizer and an electronic atomizing device, which controls the switching between a standby and a used state of the atomizer by allowing the first and second housings in the outer casing to slide relative to each other, aiming to solve the technical problem that the atomizer is prone to leakage when it is not in use.

[0007] To achieve the above objectives, this utility model provides an atomizer, the atomizer comprising:

[0008] The outer casing comprises a first housing and a second housing that are slidably disposed relative to each other.

When the second housing slides relative to the first housing to a first position, the atomizing core is offset from and isolated from the first through hole, thereby isolating the atomizing core from the air intake channel, and the atomizer is in a standby state. When the second housing slides relative to the first housing to a second position, the atomizing core is connected to the first through hole, and the atomizer is in a working state.

[0010] In some optional embodiments, the second housing is further provided with an air outlet channel located on the outer side of the liquid storage cup.

[0018] In some optional embodiments, when the second housing slides completely into the receiving cavity of the first housing from the opening of the first housing, the air outlet is located adjacent to the connecting sidewall of the first housing, which is a sidewall on the first housing opposite to the opening.

[0019] In some optional embodiments, the first height of the opening is less than the height of the second housing, the first height being the height between the upper and lower edges of the first housing forming the opening along the height direction of the first housing, and the second height of the opening is greater than the height of the second housing, the second height being the height of the opening at the starting position of the sliding connection with the second housing along the height direction of the first housing.

[0020] In some alternative embodiments, the atomizer further includes a mouthpiece mounted on one end of the first housing near the top cavity wall, the internal cavity of the mouthpiece communicating with the air outlet.

[0021] In some optional embodiments, the cross-section of the first housing in the direction in which it slides relative to the second housing is rectangular, elliptical, wavy, or irregular, and the second housing is slidably disposed within the receiving cavity of the first housing along the length of the cross-section.

[0022] or,

[0023] The first housing has a circular cross-section in the direction in which it slides relative to the second housing, and the second housing is slidably disposed within the receiving cavity of the first housing along the diameter of the circular cross-section.

[0024] In some optional embodiments, the atomizer further includes at least two spaced-apart first electrodes and at least two spaced-apart second electrodes. Each first electrode is exposed on one end face of the second housing near the bottom cavity wall of the receiving cavity and is electrically connected to the atomizing core. One end of each second electrode is exposed from the bottom cavity wall of the receiving cavity, and the other end is electrically connected to the main power supply.

[0025] When the second housing slides relative to the first housing to the first position, the corresponding electrically connected second electrode and the corresponding first electrode are offset from each other;

[0027] In some optional embodiments, each of the first electrodes has a recessed groove on one end face of the bottom cavity wall near the receiving cavity, and each of the second electrodes is an elastic electrode with one end face of each of the second electrodes being an upwardly arched arc surface. When the second housing slides relative to the first housing to the second position, the end face of the corresponding first electrode is in close contact with the groove wall surface of the corresponding groove.

[0028] And / or, at least one limiting groove is recessed on the bottom surface of the second housing and spaced apart from the atomizing core, wherein when the second housing slides relative to the first housing to the first position, one end of at least one of the second electrodes is engaged in at least one of the limiting grooves.

[0030] In some optional embodiments, the liquid storage cup has at least one liquid outlet hole on one end of the bottom cavity wall near the receiving cavity, the liquid outlet hole is connected to the mounting groove, and the liquid guide covers each of the liquid outlet holes so that the liquid guide is connected to the liquid storage cup through each of the liquid outlet holes.

[0031] To achieve the above objectives, the present invention also provides an electronic atomizing device, which includes the atomizer described in any of the above embodiments.

[0032] Compared with the prior art, the present invention has at least the following beneficial effects:

[0033] The atomizer provided by this utility model includes an outer shell and an atomizing core. The outer shell has a first shell and a second shell that are slidably disposed relative to each other. The first shell has a receiving cavity for accommodating the second shell, and the first shell has an air intake channel that communicates with the outside. The bottom wall of the receiving cavity has a first through hole that communicates with the air intake channel. The second shell has a liquid storage cup. The atomizing core is disposed at the bottom of the liquid storage cup and communicates with the liquid storage cup. When the second shell slides relative to the first shell to a first position, the atomizing core and the first through hole are offset from each other and isolated from each other, so that the atomizing core is isolated from the air intake channel, and the atomizer is in a ready-to-use state. When the second shell slides relative to the first shell to a second position, the atomizing core communicates with the first through hole, and the atomizer is in a used state. Thus, when the atomizer is in standby mode, that is, when the atomizer is not in use, the second housing can be slid relative to the first housing to the first position, causing the atomizer coil to be offset from and isolated from the first through hole, i.e., the atomizer coil is isolated from the air intake channel. At the same time, the liquid reservoir connected to the atomizer coil is also isolated from the outside world. Therefore, both the liquid reservoir and the atomizer coil are in a sealed state isolated from the outside world, which can effectively prevent the risk of leakage of atomized liquid in the liquid reservoir when the atomizer is not in use, especially when the atomizer is transported at high altitudes or at low temperatures. When not in use, such as at low pressure, the reservoir cup is in a closed state isolated from the outside world. Therefore, the internal pressure of the reservoir cup remains constant. That is, the air pressure inside the reservoir cup will not change due to the external environment of the atomizer, thus preventing leakage. When the atomizer needs to be used, the second shell can be slid relative to the first shell to the second position, so that the atomizing core is connected to the first through hole, that is, the atomizing core is connected to the air intake channel. In this way, the atomizer can start to be used and work normally. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] This invention provides an atomizer and an electronic atomizing device. The atomizer can be switched between a standby state and a working state by means of a first shell and a second shell that can slide relative to each other, which can effectively prevent the risk of leakage of atomizing liquid.

[0057] Please refer to Figures 1 to 8 As shown, this embodiment of the present invention provides an atomizer, which includes a housing 100 and an atomizing core 200. The housing 100 has a first shell 110 and a second shell 120 that are slidably disposed relative to each other. The first shell 110 has a receiving cavity 112 for accommodating the second shell 120, and an air intake channel 113 communicating with the outside is provided within the first shell 110. The bottom cavity wall 1121 of the receiving cavity 112 has a first through hole 1122 communicating with the air intake channel 113. The second shell 120 has a liquid storage cup 121, and the atomizing core 200 is disposed at the bottom of the liquid storage cup 121 and communicates with the liquid storage cup 121. Wherein, as... Figure 9 and Figure 10 As shown, the bottom cavity wall 1121 of the receiving cavity 112 is the cavity wall of the receiving cavity 112 near the lower end of the first housing 110.

[0058] When the second housing 120 slides relative to the first housing 110 to the first position, the atomizing core 200 and the first through hole 1122 are offset from each other and isolated from each other, so that the atomizing core 200 is isolated from the air intake channel 113, and the atomizer is in a standby state. When the second housing 120 slides relative to the first housing 110 to the second position, the atomizing core 200 is connected to the first through hole 1122, and the atomizer is in a working state. Here, the "first position" refers to the position where the second housing 120 slides to the point where the atomizing core 200 on the second housing 120 is covered by the bottom cavity wall 1121 of the receiving cavity 112 (e.g., ...). Figure 3 , Figure 5 and Figure 7 As shown), so that the atomizing core 200 and the first through hole 1122 are offset from each other and isolated; "second position" refers to the position where the atomizing core 200 can connect with the first through hole 1122 when the second housing 120 slides onto the second housing 120 (as shown). Figure 4 and Figure 8 (As shown).

[0059] In this embodiment, when assembling the second housing 120 and the first housing 110, it is only necessary to apply force to insert the second housing 120 into the receiving cavity 112 of the first housing 110, which is very convenient to operate.

[0060] In the embodiments of this utility model, based on the above structural design, when the atomizer is in a standby state, that is, when the atomizer is not in use, the second housing 120 can be slid relative to the first housing 110 to a first position (e.g., Figure 3 , Figure 5 and Figure 7As shown), the atomizing core 200 and the first through hole 1122 are offset from each other and isolated from each other, that is, the atomizing core 200 is isolated from the air intake channel 113. At the same time, the liquid reservoir 121 connected to the atomizing core 200 is also isolated from the outside. Therefore, both the liquid reservoir 121 and the atomizing core 200 are in a closed state isolated from the outside, which can effectively prevent the risk of leakage of the atomizing liquid in the liquid reservoir 121 when the atomizer is not in use. Especially when the atomizer is in a non-use state such as high-altitude transportation, low temperature, low pressure, etc., because the liquid reservoir 121 is in a closed state isolated from the outside, the internal pressure of the liquid reservoir 121 is always constant. That is, the air pressure in the liquid reservoir 121 will not be affected by the external environment of the atomizer, thus achieving the effect of preventing the atomizer from leaking. When the atomizer needs to be used, the second housing 120 can be slid relative to the first housing 110 to the second position (e.g., Figure 4 and Figure 8 As shown in the figure, this connects the atomizing core 200 to the first through hole 1122, that is, the atomizing core 200 to the air intake channel 113, so that the atomizer can start to be used and work normally.

[0061] Furthermore, referring to Figures 2 to 8 As shown, the second housing 120 is also provided with an air outlet channel 122, which is located on the outer side of the liquid storage cup 121. The top cavity wall 1123 of the receiving cavity 112 is provided with an air outlet 1124 that maintains communication with the outside. The bottom cavity wall 1121 of the receiving cavity 112 is also provided with a second through hole 1125 spaced apart from the first through hole 1122. The second through hole 1125 is connected to the air inlet channel 113. Figure 9 and Figure 10 As shown, the top cavity wall 1123 of the receiving cavity 112 is the cavity wall of the receiving cavity 112 near the upper end of the first housing 110. That is, along the height direction of the first housing 110, the top cavity wall 1123 and the bottom cavity wall 1121 of the receiving cavity 112 are two opposing cavity walls.

[0062] like Figure 3 , Figure 5 and Figure 7 As shown, when the second housing 120 slides to the first position relative to the first housing 110, the atomizing core 200 is offset from and isolated from the first through hole 1122, and the two ends of the air outlet channel 122 are offset from and isolated from the second through hole 1125 and the air outlet 1124, respectively. In this way, the atomizing core 200 is isolated from the air inlet channel 113 and the air outlet channel 122, so that the atomizing core 200 is in a closed state isolated from the outside world, thereby reducing the risk of liquid leakage of the atomizer.

[0063] like Figure 4 and Figure 8As shown, when the second housing 120 slides to the second position relative to the first housing 110, the atomizing core 200 is connected to the first through hole 1122, and the two ends of the air outlet channel 122 are connected to the second through hole 1125 and the air outlet 1124 respectively. This allows the air inlet channel 113, the first through hole 1122, the second through hole 1125, the air outlet channel 122, and the air outlet 1124 to be sequentially connected, enabling the atomizer to begin normal use and operation. Specifically, as... Figures 3 to 5 , Figure 7 and Figure 8 As shown, the air intake channel 113 provided on the first housing 110 and the air outlet channel 122 provided on the second housing 120 combine to form an airflow channel 101, that is, the airflow channel 101 includes an air intake channel 113 and an air outlet channel 122. In this embodiment, as... Figure 4 and Figure 8 As shown, when the second housing 120 slides to the second position relative to the first housing 110, the airflow channel 101 is L-shaped. When the user inhales the atomizer, the air pressure in the airflow channel 101 decreases, while the liquid reservoir 121 remains at a constant pressure. This results in a negative pressure, where the air pressure in the airflow channel 101 is lower than the air pressure in the liquid reservoir 121. Consequently, the atomized liquid in the liquid reservoir 121 flows into the atomizing core 200 under this negative pressure for heating and atomization. Thus, the atomizer can begin to function normally.

[0064] Furthermore, in order to keep the air intake passage 113 connected to the outside environment, in this embodiment, such as... Figure 1 , Figures 3 to 5 , Figure 7 and Figure 8 As shown, at least one air inlet 114 communicating with the outside is provided on the outer wall of the first housing 110. The air inlet 114 is connected to the air intake channel 113, so that the air intake channel 113 can always be connected to the outside through the air inlet 114.

[0065] It should be noted that, as Figure 1 , Figures 3 to 5 , Figure 7 and Figure 8 As shown, the air inlet 114 can be located on the outer side wall of the first housing 110, or the air inlet 114 can also be located on the bottom wall of the first housing 110 (not shown), as long as the air intake channel 113 can be kept connected to the outside through the air inlet 114, there is no specific limitation here.

[0066] Furthermore, referring to Figures 6 to 9As shown, the atomizer also includes a mounting member 130 installed inside the first housing 110. The mounting member 130 has an air intake channel 113 as described in the above embodiment. The end face of the mounting member 130 near the atomizing core 200 is the bottom cavity wall 1121 of the receiving cavity 112 (e.g., Figure 9 The first through hole 1122 and the second through hole 1125 are spaced apart on one end face of the mounting member 130 near the atomizing core 200 and are both connected to the air intake channel 113. In this way, by setting the mounting member 130, the air intake channel 113 can be easily set in the mounting member 130 before the mounting member 130 is installed in the first housing 110, thereby saving the trouble of machining the air intake channel 113 in the integrally formed first housing 110.

[0067] Furthermore, the material of the mounting member 130 can be plastic, glass, or metal, and the material of the second housing 120 can also be plastic, glass, or metal. Since plastic, glass, and metal are all smooth-surfaced materials, in this embodiment, by setting the materials of both the mounting member 130 and the second housing 120 to plastic, glass, or metal, the frictional resistance between the mounting member 130 and the second housing 120 can be reduced, making the relative sliding between the mounting member 130 and the second housing 120 smoother, thus improving the smoothness of the relative sliding between the first housing 110 and the second housing 120. Of course, in other embodiments, the materials of the mounting member 130 and the second housing 120 can also be other smooth-surfaced materials, as long as the second housing 120 can slide relative to the mounting member 130; this embodiment does not limit this.

[0068] It should be noted that, in order to facilitate users to observe the remaining amount of atomizing liquid in the storage cup 121, the second shell 120 can be made of transparent materials such as glass or plastic, wherein the plastic material can be acrylic.

[0069] In this embodiment, when the second housing 120 is in the second position relative to the first housing 110, a sealing structure made of sealing material such as silicone, rubber or silicone rubber can be provided between the second housing 120 and the first through hole 1122, between one end of the air outlet channel 122 and the second through hole 1125, and between the other end of the air outlet channel 122 and the air outlet hole 1124, so as to prevent air leakage during the use of the atomizer.

[0070] Furthermore, referring to Figure 2 and Figure 6As shown, the side of the first housing 110 that is slidably connected to the second housing 120 is an opening 1126, and the receiving cavity 112 is a cavity that penetrates the two opposite sidewalls of the first housing 110 in a direction perpendicular to the sliding direction of the second housing 120, with one side of the cavity being the aforementioned opening 1126. It should be noted that the side of the first housing 110 that is slidably connected to the second housing 120 is the right side of the first housing 110, that is, in this embodiment, the opening 1126 is located on the right side of the first housing 110.

[0071] Thus, when assembling the second housing 120 and the first housing 110 into one unit, the user can hold the second housing 120 with their hand and insert it into the receiving cavity 112 of the first housing 110 through the opening 1126. Since the receiving cavity 112 is a cavity that penetrates the two opposite side walls of the first housing 110 in a direction perpendicular to the sliding direction of the second housing 120, the user can hold the second housing 120 and slide it left and right relative to the first housing 110. That is, the second housing 120 can slide from the first position to the second position and from the second position to the first position, which makes it easy to switch the atomizer's usage state.

[0072] For ease of understanding, such as Figure 6 As shown, assuming the sliding direction of the second housing 120 is the X-axis direction, the direction perpendicular to the sliding direction of the second housing 120 is the Y-axis direction, and the height direction of the first housing 110 is the Z-axis direction, the receiving cavity 112 in this embodiment is a cavity that penetrates the two opposite side walls of the first housing 110 along the Y-axis direction. When the second housing 120 is assembled into the receiving cavity 112 of the first housing 110 from the opening 1126, the second housing 120 can slide left and right relative to the first housing 110 along the X-axis direction. Specifically, when the second housing 120 slides to the left relative to the first housing 110 along the X-axis, the second housing 120 can slide to a second position relative to the first housing 110. At this time, the second housing 120 is completely inserted into the receiving cavity 112 of the first housing 110, so that the atomizing core 200 is connected to the first through hole 1122, and the two ends of the air outlet channel 122 are connected to the second through hole 1125 and the air outlet 1124 respectively. In this way, the atomizer can start to be used and work normally. When the second housing 120 slides to the left relative to the first housing 110 along the X-axis... When the first housing 110 slides to the right, the second housing 120 can slide to the first position relative to the first housing 110. At this time, the atomizing core 200 is offset from and isolated from the first through hole 1122, and the two ends of the air outlet channel 122 are offset from and isolated from the second through hole 1125 and the air outlet 1124, respectively. In this way, the atomizing core 200 is isolated from the air inlet channel 113 and the air outlet channel 122, so that the atomizing core 200 is in a closed state isolated from the outside world, thereby reducing the risk of liquid leakage of the atomizer.

[0073] Furthermore, referring to Figures 2 to 8 As shown, when the second housing 120 slides fully into the receiving cavity 112 of the first housing 110 from the opening 1126, the air outlet channel 122 is located adjacent to the connecting side wall 1127 of the first housing 110, which is a side wall on the first housing 110 opposite to the opening 1126. Thus, when the second housing 120 moves to the first position relative to the first housing 110, both ends of the air outlet channel 122 are respectively offset from and isolated from the second through hole 1125 and the air outlet 1124. That is, the air outlet channel 122 can be blocked by the top side wall 1123 and the bottom side wall 1121 of the receiving cavity 112, keeping the air outlet channel 122 isolated from the outside world. This prevents dust or other particles from entering the air outlet channel 122, keeping it clean and improving the user's suction experience.

[0074] Furthermore, combined Figures 6 to 10 As shown, the first height H1 of the opening 1126 is less than the height H of the second housing 120, i.e., H1 < H. Here, the first height H1 is the height between the upper frame 1101 and the lower frame 1102 of the first housing 110 forming the opening 1126 along the height direction of the first housing 110 (e.g., ...). Figure 7 and Figure 10 Furthermore, the second height H2 of the opening 1126 is greater than the height H of the second housing 120, i.e., H2 > H, where the second height H2 is the height of the opening 1126 at the starting position of the sliding connection with the second housing 120 along the height direction of the first housing 110 (e.g., ...). Figure 8 and Figure 10 Thus, by setting H2 > H, the user can easily slide the second housing 120 into the receiving cavity 112 of the first housing 110 through the opening 1126, which is opposite to the connecting side wall 1127 of the first housing 110. Furthermore, by setting H1 < H, after the second housing 120 is slid into the receiving cavity 112 of the first housing 110, the top and bottom walls of the second housing 120 along its own height direction will abut against the upper frame 1101 and lower frame 1102 of the first housing 110, thereby preventing the second housing 120 from falling off from the opening 1126 during the process of sliding into the receiving cavity 112 of the first housing 110.

[0075] It should be noted that the height H of the second housing 120 is equal to the distance between the bottom cavity wall 1121 and the top cavity wall 1123 of the receiving cavity 112, that is, the distance between the bottom cavity wall 1121 and the top cavity wall 1123 of the receiving cavity 112 is greater than the first height H1 of the opening 1126, i.e., as Figure 9and Figure 10 As shown, in the height direction of the first housing 110, the lower edge 1102 of the first housing 110 is positioned higher than the bottom cavity wall 1121 of the receiving cavity 112; that is, the lower edge 1102 of the first housing 110 is positioned closer to the top cavity wall 1123 of the receiving cavity 112. Furthermore, as... Figure 10 As shown, in the height direction of the first housing 110, the upper edge 1101 of the first housing 110 extends downwards compared to the position of the top cavity wall 1123 of the receiving cavity 112. That is, the upper edge 1101 of the first housing 110 is located closer to the bottom cavity wall 1121 of the receiving cavity 112. In this way, when the second housing 120 is assembled into the receiving cavity 112 of the first housing 110, the upper edge 1101 and the lower edge 1102 of the first housing 110 can limit the second housing 120, thereby preventing the second housing 120 from falling off from the opening 1126.

[0076] Furthermore, such as Figures 1 to 7 As shown, the atomizer also includes a mouthpiece 140, which is mounted on one end of the first housing 110 near the top cavity wall 1123 of the receiving cavity 112. The internal cavity of the mouthpiece 140 communicates with the air outlet 1124. Thus, when the second housing 120 slides relative to the first housing 110 to the second position, it facilitates the user to inhale from the atomizer through the mouthpiece 140. It should be noted that, as... Figures 3 to 5 , Figure 7 and Figure 8 As shown, the upper end of the first housing 110 is located at the top cavity wall 1123 near the receiving cavity 112, that is, the suction nozzle 140 is installed at the upper end of the first housing 110.

[0077] Further, the cross-section of the first housing 110 in the direction of relative sliding with the second housing 120 can be rectangular, elliptical, wavy, or irregularly shaped, and the second housing 120 is slidably disposed within the receiving cavity 112 of the first housing 110 along the length of the cross-section of the first housing 110; or, the cross-section of the first housing 110 in the direction of relative sliding with the second housing 120 is circular, and the second housing 120 is slidably disposed within the receiving cavity 112 of the first housing 110 along the diameter of the circle of the cross-section. In this embodiment, as... Figure 11 As shown, the cross-section of the first housing 110 in the direction in which it slides relative to the second housing 120 is rectangular, and the second housing 120 is slidably disposed in the receiving cavity 112 of the first housing 110 along the length of the rectangle.

[0078] Furthermore, combined Figures 2 to 8As shown, the atomizer also includes at least two spaced-apart first electrodes 150 and at least two spaced-apart second electrodes 160. Each first electrode 150 is exposed on one end face of the second housing 120 near the bottom cavity wall 1121 of the receiving cavity 112 and is electrically connected to the atomizing core 200. One end of each second electrode 160 is exposed from the bottom cavity wall 1121 of the receiving cavity 112, and the other end of each second electrode 160 is electrically connected to the main power supply. It should be noted that, as... Figures 3 to 5 , Figure 7 and Figure 8 As shown, the end face of the second housing 120 near the bottom cavity wall 1121 of the receiving cavity 112 is the lower end face of the second housing 120, that is, each of the first electrodes 150 is exposed on the lower end face of the second housing 120 and is electrically connected to the atomizing core 200.

[0079] like Figure 3 , Figure 5 and Figure 7 As shown, when the second housing 120 slides to the first position relative to the first housing 110, the corresponding electrically connected second electrode 160 and the first electrode 150 are offset from each other. At this time, the connection between the first electrode 150 and the second electrode 160 is disconnected, and the atomizing core 200 is also isolated from the outside world due to the cover of the bottom cavity wall 1121 of the receiving cavity 112. Therefore, the liquid storage cup 121 will be in a closed state isolated from the outside world, which can effectively reduce the risk of leakage of the atomizing liquid in the liquid storage cup 121 due to changes in external air pressure and other factors during the transportation of the atomizer.

[0080] like Figure 4 and Figure 8 As shown, when the second housing 120 slides to the second position relative to the first housing 110, each second electrode 160 is electrically connected to the corresponding first electrode 150 again. At this time, the atomizing core 200 is connected to the air intake channel 113, and the two ends of the air outlet channel 122 are respectively connected to the air outlet 1124 and the second through hole 1125. Thus, when the atomizer starts working due to the electrical connection between each second electrode 160 and each first electrode 150, outside air enters the air intake channel 113 and mixes with the aerosol generated after the atomizing core 200 is heated and atomized. Under the user's inhalation, the outside air forms a suction airflow, thereby driving the aerosol to flow out of the outside through the second through hole 1125, the air outlet channel 122, and the air outlet 1124 for the user to inhale.

[0081] It should be noted that the "other end of the second electrode 160 is electrically connected to the main power supply" mentioned above refers to the battery element installed in the electronic atomizing device when the atomizer is assembled into the electronic atomizing device. This battery element is used to provide electrical energy to the atomizing core 200 through the second electrode 160 and the first electrode 150 to ensure the normal use of the atomizer.

[0082] Furthermore, referring to Figures 3 to 8 As shown, each first electrode 150 has a recessed groove 151 on one end face near the bottom cavity wall 1121 of the receiving cavity 112. Each second electrode 160 is an elastic electrode, and one end face of each second electrode 160 is an upwardly arched arc surface. In this embodiment, the end face of the first electrode 150 near the bottom cavity wall 1121 of the receiving cavity 112 is the lower end face of the first electrode 150, that is, a recessed groove 151 is provided on the lower end face of the first electrode 150. Wherein, as... Figure 4 and Figure 7 As shown, when the second housing 120 slides to the second position relative to the first housing 110, one end face of the corresponding second electrode 160 is in close contact with the groove wall of the corresponding groove 151. This configuration ensures reliable electrical connection between the first electrode 150 and the second electrode 160, while the groove 251 on the first electrode 150 also limits the movement of the second electrode 160, reducing the risk of shaking or even separation between the first housing 110 and the second housing 120 during atomizer use. Furthermore, when one end of the second electrode 160 (specifically the upper end of the second electrode 160) engages in the groove 151 of the first electrode 150, the elastic second electrode 160 impacts the groove wall to a certain extent, and the sliding resistance of the second housing 120 changes. This allows the user to obtain tactile feedback through the impact vibration or change in sliding resistance, enabling them to clearly perceive whether the second housing 120 has slid to the desired second position relative to the first housing 110, thus improving the user experience.

[0083] It should be noted that, in this embodiment, by setting the second electrode 160 as an elastic electrode and setting one end face of each second electrode 160 as an upwardly arched arc surface, on the one hand, each second electrode 160 can tightly abut against the first electrode 150 through its own elasticity. This improves the reliability of the electrical connection between the first electrode 150 and the second electrode 160 and helps reduce the risk of poor contact between the first electrode 150 and the second electrode 160. On the other hand, when the second housing 210 slides relative to the first housing 110 to the second position, due to the upward arched arc surface of each second electrode 160, The end face is set as an upward-arched arc surface. Therefore, during the sliding process of the second housing 210, the end of the second housing 210 near the bottom cavity wall 1121 of the receiving cavity 112 will contact and compress the end of the second electrode 160 which is set as an arc surface. When the second housing 120 slides to the second position, the second electrode 160 will be electrically connected to the corresponding first electrode 150 under the action of its own rebound force. This can avoid the second electrode 160 from blocking the sliding of the second housing 120, which would make it difficult for the second housing 210 to slide smoothly to the second position, and thus affect the normal use of the atomizer.

[0084] In this embodiment, during specific implementation, refer to Figures 3 to 5 , Figure 7 and Figure 8 As shown, one end of each second electrode 160 protrudes from the first through hole 1122 into the bottom cavity wall 1121 of the receiving cavity 112. This not only eliminates the need for additional slot structures on the bottom cavity wall 1121 of the receiving cavity 112 to expose one end of the second electrode 160, but also allows the second electrode 160 to be directly electrically connected to the first electrode 150 on the atomizing core 200 after one end of the second electrode 160 protrudes from the first through hole 1122 when the atomizing core 200 is correspondingly arranged with the first through hole 1122. This facilitates the electrical connection between the atomizing core 200 and the main power supply.

[0085] Furthermore, in some alternative embodiments, such as Figure 5As shown, at least one limiting groove 123, spaced apart from the atomizing core 200, is recessed on the bottom surface of the second housing 120. When the second housing 120 slides relative to the first housing 110 to the first position, one end of at least one second electrode 160 is engaged in the limiting groove 123. Thus, when the atomizer is in a non-use state, i.e., when the second housing 120 slides relative to the first housing 110 to the first position, the second electrode 160 is engaged in the limiting groove 123, preventing the second housing 120 from sliding out of the first housing 110 and causing the liquid reservoir 121 inside the second housing 120 to communicate with the outside, thereby further reducing the risk of leakage of the atomizing liquid. In addition, during the process of driving the second housing 120 to slide relative to the first housing 110 to the first position, when the second electrode 160 is engaged in the limiting groove 123, the user can also clearly perceive whether the second housing 120 has slid relative to the first housing 110 to the desired first position, thereby further improving the user experience.

[0086] It is understood that the number of the first electrode 150 and the second electrode 160 can be flexibly set according to actual needs. As long as it is ensured that when the second housing 120 slides to the second position relative to the first housing 110, the corresponding second electrode 160 and the corresponding first electrode 150 can be electrically connected, thereby realizing the electrical connection between the main power supply and the atomizing core 200 and ensuring the normal use of the atomizer, this embodiment does not impose specific restrictions on this.

[0087] Furthermore, referring to Figures 3 to 5 , Figure 7 and Figure 8 As shown, a mounting groove 124 is recessed on the end face of the liquid storage cup 121 near the bottom cavity wall 1121 of the receiving cavity 112. In this embodiment, the end face of the liquid storage cup 121 near the bottom cavity wall 1121 of the receiving cavity 112 is the lower end face of the liquid storage cup 121, that is, the mounting groove 124 is recessed on the lower end face of the liquid storage cup 121. The atomizing core 200 includes a liquid guide 210 and a heating element 220. The liquid guide 210 is disposed on the bottom wall of the mounting groove 124 facing the bottom cavity wall 1121 of the receiving cavity 112, and a clearance groove 126 is provided on the end face of the liquid guide 210 away from the bottom wall of the mounting groove 124. The heating element 220 is disposed in the clearance groove 126 and spaced apart from the bottom cavity wall 1121 of the receiving cavity 112. Thus, by fixing the heating element 220 in the relief groove 126 and spaced apart from the bottom cavity wall 1121 of the receiving cavity 112, not only can the friction between the heating element 220 and the bottom cavity wall 1121 of the receiving cavity 112 be avoided during the sliding of the second housing 120 relative to the first housing 110, thus preventing damage to the heating element 220, but also the smoothness of sliding between the second housing 120 and the first housing 110 can be improved.

[0088] In some alternative embodiments, refer to Figures 3 to 5 , Figure 7 and Figure 8 As shown, the liquid storage cup 121 has at least one liquid outlet hole 125 on one end of the bottom cavity wall 1121 near the receiving cavity 112. The liquid outlet hole 125 is connected to the mounting groove 124. The liquid guide 210 covers each liquid outlet hole 125 so that the liquid guide 210 is connected to the liquid storage cup 121 through each liquid outlet hole 125. Furthermore, the heating element 220 and the first electrode 150 are both fixed on the side of the liquid guide 210 facing away from the liquid outlet hole 125, and the heating element 220 is electrically connected to the first electrode 150. It should be noted that, as Figures 3 to 5 , Figure 7 and Figure 8 As shown, the lower end of the liquid storage cup 121 is located near the bottom cavity wall 1121 of the receiving cavity 112, meaning that at least one liquid outlet hole 125 is provided at the lower end of the liquid storage cup 121. The side of the liquid guide 210 facing away from the liquid outlet hole 125 is the lower side of the liquid guide 210. In this embodiment, the heating element 220 and the first electrode 150 are both fixed to the lower side of the liquid guide 210.

[0089] Based on the above structural design, when the second housing 120 slides to the second position relative to the first housing 110, the atomizing core 200 is correspondingly set with the first through hole 1122, and the two ends of the air outlet channel 122 are respectively connected to the second through hole 1125 and the air outlet 1124. Each first electrode 150 is electrically connected to the corresponding second electrode 160. In this way, when the user inhales, the atomized liquid in the liquid storage cup 121 will be conducted to the liquid guide 210 through the liquid outlet 125, and heated and atomized by the heating element 220 to form an aerosol that can be inhaled by the user. The aerosol flows into the air inlet channel 113 through the first through hole 1122. At this time, the outside air will enter the air inlet channel 113 through the air inlet 114 and bring the aerosol in the air inlet channel 113 into the air inlet channel 113. Then, it will be discharged to the outside through the second through hole 1125, the air outlet channel 122, and the air outlet 1124 in sequence for the user to inhale.

[0090] Furthermore, when the second housing 120 slides to the first position relative to the first housing 110, the side of the liquid guide 210 facing away from the liquid outlet 125 is covered by the bottom cavity wall 1121 of the receiving cavity 112 and is isolated from the air inlet channel 113 in the first housing 110. Therefore, both the atomizing core 200 and the liquid storage cup 121 are in a closed state isolated from the outside world, which can effectively reduce the risk of leakage of the atomizing liquid in the liquid storage cup 121 due to changes in external air pressure during the transportation of the atomizer.

[0091] In this embodiment, the material of the liquid conductor 210 includes any one of porous ceramics, blended fibers, fiber cotton, and sponge, and the heating element 220 includes any one of metal heating wire, metal heating mesh, metal heating plate, conductive ceramic heating plate, and conductive ceramic heating mesh. The specific details are not limited here.

[0092] It should be noted that other aspects of the atomizer provided in this embodiment can be found in the prior art, and will not be repeated here.

[0093] Correspondingly, such as Figure 12 As shown in the figure, this utility model embodiment also provides an electronic atomizing device, which includes the above-described... Figures 1 to 11 The atomizer is shown in any of the embodiments illustrated. Optionally, the electronic atomization device is applicable to fields such as electronic cigarette atomization and medical atomization, but is not limited thereto.

It should be noted that other aspects of the electronic atomizing device provided in this embodiment can be found in the prior art, and will not be repeated here either.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
