Description

Technical Field

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

[0002] Electronic atomizers generally consist of a reservoir, a coil, an airflow channel, an airflow channel, and electrodes. The coil comprises a liquid guide and a heating element. The heating element heats the atomized liquid, and the liquid guide connects the reservoir and the heating element, located within the airflow channel, thus guiding the atomized liquid from the reservoir to the heating element. The liquid guide of the coil is typically made of materials such as liquid-conducting cotton or liquid-conducting ceramic.

[0003] The working principle of an atomizer is as follows: When the heating element is working, it heats the atomizing liquid flowing from the atomizing guide. The reservoir continuously replenishes the atomizing liquid from the guide. As the atomizing liquid in the reservoir is consumed, the liquid level drops, and the air pressure inside the reservoir decreases. As a result, the negative pressure value of the air pressure inside the reservoir relative to the atmospheric pressure of the air in the airway increases. When the negative pressure value becomes large enough, the atmospheric pressure of the air in the airway exceeds the resistance of the guide liquid to the outside air entering the reservoir. Therefore, the air in the airway will pass through the guide liquid into the reservoir, which is commonly known as "return air". This creates a static balance of air pressure between the reservoir and the airway. The air pressure inside the reservoir then increases again, causing the negative pressure value of the air pressure inside the reservoir relative to the airway to decrease. Because a certain negative pressure is always maintained inside the reservoir, the atomizing liquid in the reservoir will not leak.

[0004] However, in most atomizers on the market, the outlet of the atomizer coil is directly connected to the reservoir. The atomizer controls the liquid inlet and return of the atomizer coil to the reservoir mainly by the resistance generated by the tightness or porosity of the liquid guide, as well as the negative pressure in the reservoir relative to the air pressure in the airway. This makes it difficult to reconcile liquid inlet control and leakage prevention during use. Sometimes, if the liquid guide is tight enough to press the outlet, it can effectively prevent gas from entering the reservoir, but it can also cause excessive resistance, making it difficult for the atomized liquid to flow into the airway. On the other hand, if the liquid guide is too loose to press the outlet, although the reservoir can return air normally, leakage is likely to occur.

[0005] Specifically, relying solely on the tightness and porosity of the liquid guide to control liquid inflow and leakage can easily lead to the following problems:

[0006] 1. The atomizer coil holder typically has two or more liquid inlet holes on its side wall. These inlet holes connect to the liquid outlet holes on the reservoir. If the atomizer is in an abnormal usage position, such as being laid flat, tilted, or upside down, the liquid inlet holes on the coil holder will be exposed above the liquid surface. At this time, due to the reduced or zero gravity of the liquid and the reduced resistance from the liquid guide, the static pressure balance between the reservoir and the airway is broken. The air pressure in the airway is much greater than the air pressure in the reservoir. As a result, the air in the airway enters the reservoir through the liquid guide and the inlet holes, making the air pressure in the reservoir equal to the atmospheric pressure in the airway. In other words, the negative pressure of the reservoir relative to the airway decreases or even becomes almost zero, causing the liquid in the reservoir to flow into the airway through the liquid guide, resulting in leakage. Furthermore, when the amount of atomizing liquid in the reservoir cup decreases to a certain level, the air pressure inside the reservoir cup also decreases. As a result, the negative pressure value of the reservoir cup relative to the air passage also becomes larger, and air in the air passage will also enter the reservoir cup through the liquid guide and liquid inlet, causing leakage.

[0007] 2. When using water-based atomizing fluid in the atomizer, the high surface tension of the water-based atomizing fluid requires more energy to break the water molecule bonds during the conduction process to the guide fluid. The excessive surface tension of the water-based atomizing fluid makes it difficult for it to conduct to the guide fluid, which can easily lead to insufficient liquid supply to the atomizer coil and dry burning. When not in use, the low viscosity of the water-based atomizing fluid makes it easy for it to leak into the air passage, resulting in leakage.

[0008] 3. Whether the liquid inlet on the atomizer core holder is immersed in the atomizing liquid. Because the level of atomizing liquid in the reservoir cup varies, there may be visual errors. This may lead to the user using the atomizer when there is insufficient atomizing liquid, resulting in dry burning. Summary of the Invention

[0014] An atomizing core, disposed inside the outer shell, includes a heating element, a liquid guide, and an atomizing core shell.

[0044] To achieve the above objectives, this application also provides an electronic atomizing device, including the atomizer described in any one of the above claims.

[0045] The beneficial effects of the atomizer and electronic atomization device provided in this application are:

[0046] 1. The atomizer provided in this application embodiment has a plurality of capillaries spaced apart from each other in at least a portion of the side wall of the liquid inlet tube control. The capillaries are at least radially spaced from the liquid inlet hole to form a gap. Due to the capillary action of the capillaries, even when the surface tension of the atomizing liquid is relatively high, the atomizing liquid in the reservoir cup can flow into the gap along the capillaries. Furthermore, due to the surface tension of the atomizing liquid itself, the atomizing liquid entering the gap between the capillaries and the liquid inlet hole... A layer of atomized liquid film will form at this gap. In this way, if the weight of the atomized liquid itself and the air pressure in the reservoir cup decrease, such as when the atomizer is laid flat or upside down, or when the atomized liquid in the reservoir cup decreases, the reservoir cup can increase the resistance of external gas to entering the reservoir cup through the atomized liquid film. That is, the atomized liquid film blocks the air in the air passage from entering the reservoir cup through the liquid guide and liquid inlet, thereby ensuring that the atomized liquid in the reservoir cup is difficult to flow into the air passage through the liquid inlet and liquid guide, and avoiding liquid leakage from the atomizer.

[0047] 2. When the atomizer uses a water-based atomizing liquid, in this embodiment, a capillary is provided on the inlet pipe control, allowing the water-based atomizing liquid in the reservoir cup to enter the gap along the capillary through capillary action. When the reservoir cup is full of atomizing liquid, the water-based atomizing liquid can break the water-based atomizing liquid film formed in the gap due to its own gravity and the large air pressure in the reservoir cup. That is, it can break the surface tension of the large water molecule bonds in the water-based atomizing liquid, allowing the water-based atomizing liquid to be smoothly conducted through the inlet hole to the guide liquid and then heated and atomized by the heating element, avoiding dry burning. In addition, by setting the capillary at least radially spaced from the inlet hole and forming a gap with the inlet hole, and by forming a water-based atomizing liquid film after the capillary and the gap are filled with water-based atomizing liquid, it can prevent the water-based atomizing liquid from easily leaking into the air passage even when the atomizer is not in use, due to the low viscosity of the water-based atomizing liquid. This can prevent leakage.

[0048] 3. Since the capillaries in this embodiment are all connected to the liquid storage cup and can store a portion of the atomizing liquid, even if there is no continuous flow of atomizing liquid into the capillaries for a short period of time, the atomizing liquid stored in the capillaries can still be heated and atomized through the liquid inlet and the liquid guide to the heating element. This avoids the phenomenon of dry burning due to insufficient liquid, such as the user's visual error causing a lack of atomizing liquid during use, and extends the service life of the atomizer.

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

[0077] Please refer to Figure 1-13This application provides an atomizer, which includes a housing 100, a sleeve 200, a base 300, an atomizing coil 400, and a liquid inlet control 500. The sleeve 200 is connected to the inside of the top side of the housing 100, and the base 300 is connected to the bottom side of the housing 100. The atomizing coil 400 is disposed inside the housing 100, and the atomizing coil 400 includes an atomizing coil shell 420, a liquid guide 430, and a heating element (not shown). The heating element and the liquid guide 430 are interconnected and sleeved in the atomizing coil shell 420, and one side of the liquid guide 430 is connected to the inner wall of the atomizing coil shell 420. The two ends of the atomizing core shell 420 are connected to the sleeve 200 and the base 300, respectively. A liquid storage cup 600 is formed between the outer side wall of the sleeve 200, the outer side wall of the atomizing core shell 420, and the inner side wall of the outer shell 100. At least one liquid inlet hole 410 communicating with the liquid storage cup 600 is provided through the side wall of the atomizing core shell 420. The liquid inlet tube control 500 is located at the bottom inside the liquid storage cup 600 and is sleeved on the outer periphery of the atomizing core shell 420. The liquid inlet tube control 500 is hollow cylindrical. At least a portion of the side wall of the liquid inlet tube control 500 is provided with a plurality of capillaries 510 spaced apart from each other. The capillaries 510 are at least radially spaced from the liquid inlet hole 410 to form a gap 520.

[0078] Among them, such as Figure 4 , 8 As shown in Figure 12, the outer shell 100 and the sleeve 200 can be separate structures (not shown), that is, the outer shell 100 has a first mounting hole 110, and the sleeve 200 is fitted onto the top side of the outer shell 100 through the first mounting hole 110 and extends toward the interior of the outer shell 100. Of course, the outer shell 100 and the sleeve 200 can also be an integral structure, that is, the sleeve 200 is integrally formed inside the top side of the outer shell 100 (e.g., Figure 4 , 8 (as shown in Figure 12), no limitation is made here.

[0079] The outer casing 100 also has a second mounting hole 120 opposite to the first mounting hole 110, and the base 300 is mounted on the bottom side of the outer casing 100 through the second mounting hole 120. Here, the top and bottom sides of the outer casing 100 are only relative to the current placement of the atomizer in the figure, and should not be construed as limiting the orientation of the sleeve 200 and the base 300. For example, in other embodiments, the sleeve 200 is mounted inside the bottom side of the outer casing 100, and the base 300 is mounted on the top side of the outer casing 100, which is not limited here.

[0080] Of course, the base 300 and the outer casing 100 can be connected by a snap-fit ​​method, or by other methods, such as a threaded connection. The connection between the base 300 and the outer casing 100 is a sealed connection to ensure the sealing performance of the liquid storage cup 600.

[0081] Alternatively, the base 300 and the outer casing 100 can also be an integral structure.

[0082] Furthermore, such as Figure 3-4 As shown in Figures 7-8 and 11-12, the base 300 has a liquid injection hole 310, through which external atomizing liquid is injected into the storage cup 600. The base 300 also has a liquid injection hole plug 320, which is inserted into the liquid injection hole 310 to prevent the atomizing liquid in the storage cup 600 from flowing out through the liquid injection hole 320. When it is necessary to add atomizing liquid, simply remove the liquid injection hole plug 320 and add liquid to the storage cup 600.

[0083] like Figure 2 , 6 As shown in Figure 10, the atomizing core 400 also includes an atomizing core holder 440, which is mounted on the base 300. One end of the atomizing core shell 420 is connected to the sleeve 200, and the other end is connected to the atomizing core holder 440. The heating element and the guiding liquid 430 are disposed within the atomizing core shell 420 and connected to the guiding liquid 430. A liquid storage cup 600 is formed between the outer wall of the sleeve 200, the outer wall of the atomizing core shell 420, and the inner wall of the outer shell 100. At least one liquid inlet hole 410 communicating with the liquid storage cup 600 is provided through the side wall of the atomizing core shell 420, allowing the atomizing liquid in the liquid storage cup 600 to be introduced into the guiding liquid 430 through the liquid inlet hole 410, and then conducted to the heating element through the guiding liquid 430 for heating and atomization to form an aerosol.

[0084] The atomizer also includes a mouthpiece 700, which is mounted on the sleeve 200 and connected to the space inside the sleeve 200 to form an air passage 710. The air passage 710 is used to conduct the aerosol formed after being heated and atomized by the heating element.

[0085] Furthermore, in order to seal the gap between the atomizing core shell 420 and the sleeve 200, the atomizer in this embodiment also includes a sealing ring 800, which is disposed at the connection between the atomizing core shell 420 and the sleeve 200. The sealing ring 800 serves two purposes: firstly, it prevents the atomizing liquid in the reservoir 600 from leaking into the air passage 710 when the liquid level in the reservoir 600 exceeds the connection between the atomizing core shell 420 and the sleeve 200, thus preventing leakage from the atomizer; secondly, it prevents air from entering the reservoir 600 from the connection between the atomizing core shell 420 and the sleeve 200 when the liquid level in the reservoir 600 is lower than the connection between the atomizing core shell 420 and the sleeve 200. This prevents the atomizing liquid in the reservoir 600 from flowing into the air passage 710 through the liquid inlet 410 and the guide liquid 430, thus preventing leakage from the atomizer, as the air pressure in the reservoir 600 becomes equal to the atmospheric pressure in the air passage 710 (i.e., the negative pressure in the reservoir 600 is reduced relative to the air passage 710). Regardless of whether the atomizing liquid in the reservoir cup 600 is sufficient, the sealing ring 800 provided between the atomizing core shell 420 and the sleeve 200 can further ensure that the atomizing liquid in the reservoir cup 600 will not leak from the connection between the atomizing core shell 420 and the sleeve 200 or from the liquid inlet 410 into the air passage 710.

[0086] It should be noted that the atomizing core 400 in this application embodiment does not only include the atomizing core shell 420, the liquid guide 430, the heating element and the atomizing core seat 440, but also includes structures such as electrodes and insulating seats. That is, the structure of the atomizing core 400 in this application embodiment has not been improved. In other words, the atomizing core 400 is not limited to the structure of the atomizing core 400 described above.

[0087] In this embodiment, the liquid inlet tube control 500 is sleeved on the outer periphery of the atomizing core shell 420 and located at the bottom inside the liquid storage cup 600. The bottom inside the liquid storage cup 600 is the side of the liquid storage cup 600 closest to the base 300, that is, the liquid inlet tube control 500 is located on the side of the liquid storage cup 600 closest to the base 300 and is connected to the base 300. Of course, the liquid inlet tube control 500 can also be connected to the atomizing core holder 440, which is not limited here.

[0088] Specifically, at least a portion of the sidewall of the liquid inlet pipe control 500 is provided with a plurality of spaced-apart capillaries 510, and the plurality of capillaries 510 are connected to the liquid storage cup 600. In one embodiment of this application, as Figure 3 , Figure 4As shown, a capillary 510 is provided on a portion of the sidewall of the liquid inlet tube control 500, and the capillary 510 on this portion of the sidewall is arranged radially and spaced apart from the liquid inlet hole 410 to form a gap 520. There are also some cases not shown, such as the portion of the inner sidewall of the liquid inlet tube control 500 that is offset from the liquid inlet hole 410, which can be attached to the outer sidewall of the atomizing core shell 420, or it can be arranged with a certain gap, or it can also be provided with a capillary 510 that can contact the outer sidewall of the atomizing core shell 420, or it can be arranged with a gap 520 formed relative to the outer sidewall of the atomizing core shell 420. The specific details are not limited here.

[0089] Furthermore, capillaries 510 can be provided on all sidewalls of the liquid inlet pipe control 500. The capillaries 510 located at the liquid inlet hole 410 are arranged opposite to the liquid inlet hole 410 to form a gap 520. The capillaries 510 at other locations can be arranged opposite to the outer sidewall of the atomizing core shell 420 to form a gap 520, or they can be attached to the outer sidewall of the atomizing core shell 420.

[0090] It should be noted that one of the functions of the capillary 510 is that, due to its capillary structure, it can guide the atomized liquid from the reservoir cup 600 into itself through capillary action. This is analogous to placing a hair on a droplet; the droplet, initially hemispherical, will move some of its liquid along the hair. Since the atomized liquid has a certain surface tension, especially high-water-content liquids like water-based liquids, the capillary 510 can disrupt this surface tension, continuously guiding the liquid from the reservoir cup 600 into the capillary 510. From there, the liquid flows through the capillary 510 to the gap 520 and into the liquid inlet 410 of the atomizing core shell 420, ultimately flowing into the guide liquid 430. In this way, the capillary 510 enables the atomizing liquid in the reservoir 600 to flow into the guide liquid 430 more quickly and smoothly, so as to provide heating and atomization for the heating element connected to the guide liquid 430. This not only prevents dry burning, but also continuously produces sufficient smoke, thereby improving the taste of the smoke and enhancing the user experience.

[0091] Furthermore, it should be noted that the function of gap 520 is that when gap 520 is filled with atomizing liquid, due to the surface tension of the atomizing liquid itself and the relatively narrow space of gap 520, an atomizing liquid film will form at gap 520. Thus, when the weight of the atomizing liquid itself and the air pressure inside the reservoir 600 decrease—for example, when the atomizer is placed horizontally or inverted, or when the atomizing liquid in the reservoir 600 decreases—the atomizing liquid film can increase the external pressure. The resistance to gas entering the reservoir 600, that is, the atomizing liquid film can block the air (i.e., the outside atmosphere) in the air passage 710 from entering the reservoir 600 through the liquid inlet 410. This can prevent the atomizing liquid in the reservoir 600 from flowing into the air passage 710 through the liquid inlet 410 and the guide liquid 430 due to the air pressure in the reservoir 600 being equal to the atmospheric pressure in the air passage 710 (that is, the negative pressure of the reservoir 600 relative to the air passage 710 being reduced), thus preventing the atomizing liquid in the reservoir 600 from flowing into the air passage 710 through the liquid inlet 410 and the guide liquid 430, causing the atomizer to leak.

[0092] In this embodiment, as described above, the capillary 510 is used to guide the atomizing liquid. When the atomizer is used, when the atomizing liquid in the reservoir 600 is sufficient, not only is the air pressure in the reservoir 600 greater than the air pressure in the air passage 710, but also due to the capillary effect of the capillary 510 and the greater gravity of the atomizing liquid in the reservoir 600, the atomizing liquid in the reservoir 600 can quickly flow through the capillary 510 and into the gap 520. In this case, even if an atomizing liquid film is formed at the gap 520, the atomizing liquid can continuously flow from the reservoir 600 into the gap 520. That is, the atomizing liquid can also break the surface tension of the atomizing liquid film and flow smoothly to the guide liquid 430 and the heating element, so that the heating element heats and atomizes the atomizing liquid. In other words, when the atomizing liquid in the reservoir 600 is sufficient, the atomizing liquid can flow more quickly and in greater quantities to the heating element through the capillary 510 for heating and atomization, thus continuously producing a large amount of smoke. This not only prevents dry burning but also enhances the user experience and the taste of inhalation.

[0093] When the atomizer is placed flat, tilted, or inverted, or when the amount of atomizing liquid in the reservoir 600 decreases, the air pressure in the reservoir 600 decreases, and the weight of the atomizing liquid in the reservoir 600 decreases. At this time, the atomizing liquid film formed at the gap 520 between the capillary 510 and the liquid inlet 410 due to the surface tension of the atomizing liquid can prevent air from entering the reservoir 600 through the liquid guide 430 and the liquid inlet 410 when the amount of atomizing liquid in the reservoir 600 decreases to a certain level, that is, when the air pressure in the reservoir 600 decreases accordingly (and the negative pressure value of the reservoir 600 relative to the air passage 710 also becomes larger). This ensures that the internal air pressure of the reservoir 600 will not be almost equal to the atmospheric pressure in the air passage 710, thus preventing leakage. In other words, when the atomizing liquid is placed horizontally, at an angle, or upside down, or when the atomizing liquid in the storage cup 600 decreases, the atomizing liquid film formed at the gap 520 can play its role in preventing air in the air passage 710 from entering the storage cup 600 through the liquid guide 430 and the liquid inlet 410, thus preventing leakage caused by the internal air pressure of the storage cup 600 being almost equal to the atmospheric pressure in the air passage 710.

[0094] Furthermore, the capillary 510 also has another function: it can store a portion of the atomizing liquid. So even when the liquid reservoir 600 is low, when the user uses the atomizer, the capillary 510 can guide the liquid 430 and the heating element to provide the stored atomizing liquid, which can temporarily alleviate the dry burning phenomenon.

[0095] The functions and working principles of the capillary 510 and the gap 520 in the embodiments of this application have been described in detail above. Based on the above description, the embodiments of this application are further described in detail below.

[0096] In some structural designs of the atomizer provided in the embodiments of this application, please refer to... Figures 2 to 5At least a portion of the sidewall of the liquid inlet pipe control 500 is provided with a plurality of mutually spaced capillaries 510, and the capillaries 510 are arranged at least radially spaced from the liquid inlet hole 410 to form a gap 520. Due to the capillary action of the capillaries 510, even when the surface tension of the atomizing liquid is relatively high, the atomizing liquid in the liquid storage cup 600 can flow into the gap 520 along the capillaries 510. Furthermore, due to the surface tension of the atomizing liquid itself, the atomizing liquid entering the gap 520 between the capillaries 510 and the liquid inlet hole 410 will form an atomizing liquid film at the gap 520. In this way, when the weight of the atomizing liquid and the air pressure inside the reservoir 600 decrease, such as when the atomizer is placed horizontally, at an angle, or upside down, or when the amount of atomizing liquid in the reservoir 600 decreases, the resistance of external gas entering the reservoir 600 can be increased through the atomizing liquid film. That is, the atomizing liquid film blocks the air in the airway from entering the reservoir 600 through the liquid guide 430 and the liquid inlet 410, thereby ensuring that the air pressure inside the reservoir 600 is maintained at a sufficiently negative pressure relative to the air pressure in the airway. This makes it difficult for the atomizing liquid in the reservoir 600 to flow into the airway through the liquid inlet 410 and the liquid guide 430, thus preventing the atomizer from leaking.

[0097] Furthermore, when the atomizer uses a water-based atomizing liquid, in this embodiment, a capillary 510 is provided on the inlet pipe control 500, allowing the water-based atomizing liquid in the reservoir 600 to have its surface tension broken by the capillary action of the capillary 510, thus allowing the water-based atomizing liquid to enter the gap 520 along the capillary 510. When the water-based atomizing liquid in the reservoir 600 is sufficient, the water-based atomizing liquid can break the water-based atomizing liquid film formed in the gap 520 by its own gravity and the relatively large air pressure in the reservoir 600, that is, it can break the surface tension of the large water molecule bonds in the water-based atomizing liquid, allowing the water-based atomizing liquid to be smoothly conducted through the inlet hole 410 to the guide liquid 430 and then heated and atomized by the heating element, avoiding dry burning.

[0098] Furthermore, by setting the capillary 510 to be at least radially spaced from the liquid inlet hole 410 in the liquid inlet pipe control 500 and forming a gap 520, and by forming a water-based atomizing liquid film after the capillary 510 and the gap 520 are filled with water-based atomizing liquid, it is possible to prevent the water-based atomizing liquid from easily leaking into the air passage even when the atomizer is not in use due to its low viscosity, thereby preventing leakage.

[0099] Furthermore, as mentioned above, since the capillaries 510 in this embodiment are all connected to the liquid storage cup 600, and a portion of the atomizing liquid can be stored in the capillaries 510, even if there is no continuous flow of atomizing liquid into the capillaries 510 for a short period of time, the atomizing liquid stored in the capillaries 510 can still flow to the heating element through the liquid inlet 410 and the liquid guide 430 for heating and atomization. This avoids the phenomenon of dry burning caused by insufficient liquid when the atomizer is used due to a lack of atomizing liquid, such as the user's visual error (i.e., mistakenly believing that the atomizing liquid is sufficient when it is actually insufficient). This extends the service life of the atomizer.

[0100] In this embodiment, the liquid inlet tube control 500 can be hollow cylindrical, that is, the liquid inlet tube control 500 is a hollow cylindrical body that is enclosed, and the hollow cylindrical liquid inlet tube control 500 is sleeved on the outer periphery of the atomizing core shell 420 near the base 300. The capillary portion 510 is provided on the inner sidewall of the liquid inlet tube control 500.

[0101] The area on the inner wall of the liquid inlet pipe control 500 that is misaligned with the liquid inlet hole 410 can be spaced apart or fitted to the outer wall of the atomizing core shell 420. Continuous or discontinuous capillaries 510 (not shown) can be provided on this inner wall; of course, this inner wall can also be left untreated. Alternatively, the area on the inner wall of the liquid inlet pipe control 500 that is misaligned with the liquid inlet hole 410 can be hollowed out (e.g., ...). Figure 3-5 (As shown), no limitation is made here.

[0102] Furthermore, the capillary portion 510 can be configured as a capillary groove extending from top to bottom along the length direction of the inlet pipe control 500 on the inner wall of the inlet pipe control 500, with the capillary grooves spaced apart from each other along the circumference of the inlet pipe control 500. Since the inlet pipe control 500 is a hollow cylinder, that is, the length direction of the inlet pipe control 500 is either the axial direction or the height direction of the inlet pipe control 500, meaning that the capillary groove extends along the axial direction or the height direction of the inlet pipe control 500 into the inner wall of the inlet pipe control 500, but does not penetrate the outer wall of the inlet pipe control 500. In other words, the capillary groove extends from top to bottom along the length direction of the inlet pipe control 500 into the inner wall of the inlet pipe control 500.

[0103] Specifically, the outer wall of the liquid inlet pipe control 500 can be spaced apart from the inner wall of the housing 100 (e.g., Figure 2As shown in the figure, since the inlet tube control 500 is located at the bottom inside the liquid storage cup 600 and a capillary 510 is provided on the side wall of the inlet tube control 500, the atomizing liquid in the liquid storage cup 600 will be introduced into the gap 520 along the capillary 510, so that both the capillary 510 and the gap 520 will be filled with atomizing liquid. In addition, the outer side wall of the inlet tube control 500 can also be abutted against the inner side wall of the outer casing 100 (not shown), and the inlet tube control 500 is still located at the bottom inside the liquid storage cup 600. At this time, the atomizing liquid in the liquid storage cup 600 can also be introduced into the gap 520 along the capillary 510, so that both the capillary 510 and the gap 520 will be filled with atomizing liquid.

[0104] When the outer wall of the inlet pipe control 500 abuts against the inner wall of the outer casing 100, in order to prevent the inlet pipe control 500 from blocking the external atomizing liquid from being injected into the storage cup 600 from the injection hole 310, in this embodiment, a liquid passage hole 530 is also provided on the inlet pipe control 500 at the position corresponding to the injection hole 310 (see reference). Figure 9 The position of the liquid passage hole is offset from that of the capillary 510. The liquid passage hole 530 is used to connect the liquid injection hole 310 and the liquid storage cup 600.

[0105] In this embodiment, the width of the capillary groove can be set to 0.1mm to 1.2mm. Further, the width of the capillary groove can be set to 0.2mm to 0.5mm.

[0106] Furthermore, the width of the capillary groove is set to 0.3mm to 0.4mm.

[0107] It should be noted that, because the capillary groove can store atomizing liquid, when the atomizer is inverted, the atomizing liquid stored in the capillary groove can still be retained in the capillary groove due to the capillary effect, and will not flow back into the liquid storage cup 600. When the atomizing liquid in the liquid storage cup 600 is insufficient, the atomizing liquid stored in the capillary groove can be introduced into the liquid guide 430 through the liquid inlet 410 and then heated and atomized by the heating element to prevent dry burning.

[0108] In this embodiment, the capillary groove is also used to guide the atomizing liquid into the gap 520. That is, the atomizing liquid in the storage cup 600 will flow along the capillary groove to the gap 520. After the gap 520 is filled with atomizing liquid, an atomizing liquid film is formed. When the atomizing liquid in the storage cup 600 decreases, the atomizing liquid film in the gap 520 can prevent the negative pressure in the storage cup 600 from decreasing due to the external atmospheric pressure being greater than the pressure inside the storage cup 600. This would prevent gas from entering the storage cup 600 through the liquid inlet 410, causing the atomizing liquid to flow from the capillary groove to the liquid guide 430, thus causing leakage.

[0109] When the atomizer is in use and the liquid reservoir 600 contains sufficient atomized liquid, a negative pressure is created within the air passage 710. This means the external atmospheric pressure within the air passage 710 is less than the sum of the atmospheric pressure within the liquid reservoir 600 and the weight of the atomized liquid. This causes the atomized liquid in the liquid reservoir 600 to flow along the capillary groove into the gap 520, overcoming the surface tension of the atomized liquid film within the gap 520. It then flows through the inlet hole 410 into the guide liquid 430, where it is heated and atomized by the heating element. When the atomizer is in use and the liquid reservoir 600 contains insufficient atomized liquid, the capillary groove provides the guide liquid 430 and the heating element with the stored atomized liquid, temporarily alleviating the dry-burning phenomenon.

[0110] Of course, in order to enable the capillary groove to store more atomizing liquid and to allow the atomizing liquid to flow more smoothly into the vicinity of the heating element in the air passage 710 after flowing into the capillary groove, the longitudinal depth of the capillary groove in this embodiment can be greater than 0.5 mm. Specifically, it can be set according to the size of the liquid storage cup 600. The greater the longitudinal depth of the capillary groove, the more liquid it stores and the better the liquid storage effect.

[0111] Optionally, the depth of the capillary groove is 2mm to 8mm.

[0112] Since the capillary groove can store atomizing liquid, when the atomizer is used, the atomizing liquid in the reservoir 600 will flow along the capillary groove into the gap 520 under the capillary action and flow towards the liquid inlet 410, thereby disrupting the atomizing liquid film formed at the gap 520. In order to ensure that the atomizing liquid in the reservoir 600 flows smoothly into the gap 520 along the capillary groove, in this embodiment, the distance between two adjacent capillary grooves is 0.1mm to 2.0mm. That is, by reasonably distributing the distance between the capillary grooves, the effect of smooth liquid guidance is achieved.

[0113] Furthermore, the spacing between two adjacent capillary grooves is 0.2mm to 0.5mm, which allows for smoother liquid flow and achieves better liquid flow effect.

[0114] In this embodiment, the capillary 510 and the liquid inlet 410 are spaced apart to form a gap 520. In order to form an atomized liquid film after the gap 520 is filled with atomizing liquid, the radial dimension of the gap 520 along the liquid inlet control 500 is 0.1mm to 1.5mm. If the radial dimension of the gap 520 along the liquid inlet control 500 is less than 0.1mm, the process is difficult to implement and it is not easy to guide the liquid; if the radial dimension of the gap 520 along the liquid inlet control 500 is greater than 1.5mm, it is difficult to form an atomized liquid film after the gap 520 is filled with atomizing liquid.

[0115] Furthermore, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.2mm to 0.8mm.

[0116] Furthermore, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.3mm to 0.5mm. The smaller the radial dimension of the gap 520 along the liquid inlet pipe control 500, the greater the surface tension of the atomized liquid film formed, meaning that it is less likely for gas to break the atomized liquid film and enter the liquid storage cup 600, thus preventing leakage of the atomized liquid in the liquid storage cup 600.

[0117] In this embodiment, the radial dimension of the gap 520 along the liquid inlet pipe control 500 can be uniformly equal throughout the circumference of the entire liquid inlet pipe control 500. Alternatively, the radial dimension of the gap 520 along the liquid inlet pipe control 500 can gradually increase or decrease in the direction toward the sleeve 200, as long as the radial dimension of the gap 520 along the liquid inlet pipe control 500 satisfies the condition that the gap 520 can form an atomized liquid film after being filled with atomizing liquid.

[0118] The capillary groove can be a straight groove, a curved groove, a wavy groove, or an irregularly shaped groove. Of course, in other embodiments, the capillary groove can also be other types of grooves, such as a combination of straight and curved grooves, or a combination of straight and wavy grooves, etc., and is not limited here.

[0119] In this embodiment, the dimension of the gap 520 along the axial direction of the liquid inlet pipe control 500 is greater than or equal to the diameter of the liquid inlet hole 410. That is, the dimension of the capillary 510 in the height direction (axial direction) of the liquid inlet pipe control 500 is greater than or equal to the diameter of the liquid inlet hole 410, thereby ensuring that the capillary 510 is at least spaced apart from the liquid inlet hole 410 to form a gap 520.

[0120] Please refer to the following: Figure 6-9 As shown, Figures 6 to 9 This is a schematic diagram of some other structural designs in embodiments of this application. Capillaries 510 are provided on the entire inner wall of the liquid inlet tube control 500. As mentioned above, the capillary action of the capillaries 510 guides the atomizing liquid from the storage cup 600 to flow rapidly into the capillaries 510. Furthermore, the capillaries 510, the outer wall of the atomizing core shell 420, and the position of the liquid inlet hole 410 are radially spaced apart in the liquid inlet tube control 500, forming a gap 520. The capillary 510 and the outer wall of the atomizing core shell 420 are respectively spaced apart to form gaps 520, so that when the gap 520 is filled with atomizing liquid, an atomizing liquid film will be formed between the capillary 510 and the liquid inlet 410. This atomizing liquid film is used to increase the resistance of air entering the liquid storage cup 600. That is, the atomizing liquid film blocks the air in the air passage from entering the liquid storage cup 600, thereby ensuring that the internal air pressure of the liquid storage cup 600 is not equal to the atmospheric pressure of the air in the air passage, thus preventing the atomizer from leaking liquid.

[0121] Furthermore, such as Figures 2 to 5In the embodiments described, the capillary 510 can be configured as a capillary groove extending from top to bottom along the length direction of the liquid inlet pipe control 500 on the inner sidewall of the liquid inlet pipe control 500, and the capillary grooves are spaced apart from each other along the circumference of the liquid inlet pipe control 500. The specific details will not be elaborated here.

[0122] In this embodiment, the outer wall of the liquid inlet pipe control 500 abuts against the inner wall of the outer casing 100, while the liquid inlet pipe control 500 remains at the bottom of the liquid storage cup 600. This means that the atomizing liquid in the liquid storage cup 600 is introduced into the capillary 510 and the gap 520, filling them with atomizing liquid. The width of the capillary groove, the longitudinal depth of the capillary groove, the spacing between two adjacent capillary grooves, and the radial dimension of the gap 520 along the liquid inlet pipe control 500 are all consistent with the above description and will not be repeated here.

[0123] like Figure 10-13 As shown, the capillary portion 510 can be a capillary groove formed circumferentially on the side wall of the inlet pipe control 500, and the capillary grooves are spaced apart from each other along the length direction of the inlet pipe control 500. Alternatively, the capillary portion 510 can also be a capillary groove formed axially on the side wall of the inlet pipe control 500, and the capillary grooves are spaced apart from each other along the circumferential direction of the inlet pipe control 500. Alternatively, the capillary portion 510 can also be a capillary groove formed at an angle to the axial direction of the inlet pipe control 500 on the side wall of the inlet pipe control 500, and the capillary grooves are spaced apart from each other along the circumferential direction of the inlet pipe control 500.

[0124] The outer wall of the liquid inlet pipe control 500 is spaced apart from the inner wall of the outer casing 100. Since the liquid inlet pipe control 500 is located at the bottom of the liquid storage cup 600, the atomized liquid in the liquid storage cup 600 is introduced into the gap 520 along the capillary 510, so that both the capillary 510 and the gap 520 are filled with atomized liquid. The capillary groove is a narrow strip-shaped through hole opened on the side wall of the liquid inlet pipe control 500, in which the atomized liquid can be stored.

[0125] In this embodiment, the width of the capillary channel is set to 0.1mm to 1.2mm.

[0126] Furthermore, the width of the capillary channel is set to 0.2mm to 0.5mm.

[0127] Furthermore, the width of the capillary channel is set to 0.3mm to 0.4mm.

[0128] It should be noted that capillary channels can achieve the same technical effects as described above, which will not be repeated here. Furthermore, the smaller the width of the capillary channel, the better its flow-guiding effect.

[0129] In this embodiment, the distance between two adjacent capillary channels is 0.1mm to 2.0mm. That is, by reasonably distributing the distance between the capillary channels, the effect of smooth liquid flow can be achieved.

[0130] Furthermore, the spacing between two adjacent capillary channels is 0.2mm to 0.5mm, which allows for smoother liquid flow and achieves a better liquid flow effect.

[0131] In this embodiment, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.1mm to 1.5mm.

[0132] Furthermore, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.2mm to 0.8mm.

[0133] Furthermore, the radial dimension of the gap 520 along the inlet pipe control 500 is 0.3mm to 0.5mm.

[0134] It should be noted that gap 520 can achieve the same technical effect as described above, which will not be repeated here. Furthermore, the smaller the radial dimension of gap 520 along the liquid inlet pipe control 500, the greater the surface tension of the atomized liquid film formed. This means that gas is less likely to break the atomized liquid film and enter the liquid storage cup 600, thus preventing a reduction in negative pressure within the liquid storage cup 600 and resulting in leakage of the atomized liquid.

[0135] The capillary channel can be a straight channel, a bent channel, a wavy channel, or an irregular channel. Of course, in other embodiments, the capillary channel can also be other types of channels, such as a combination of a straight channel and a bent channel, or a combination of a straight channel and a wavy channel, etc., and is not limited here.

[0136] It should be understandable that Figure 2-5 , Figure 6-9 as well as Figure 10-13 Although the liquid inlet tube control 500 in these three embodiments is labeled "500", the liquid inlet tube control 500 differs in structure and capillary 510 setting method, but the effect achieved is the same.

[0137] Based on all the above embodiments, please refer to Figure 10-12 As shown, the atomizer may also include a liquid guide sleeve 900 (wherein, Figure 2-4The liquid guide sleeve 900 (not shown in Figures 6-8) is a hollow cylindrical sleeve fitted into the gap 520 between the capillary 510 and the outer wall of the atomizing core shell 420. During assembly, the liquid guide sleeve 900 is first fitted onto the outer wall of the atomizing core shell 420, with the inner wall of the liquid guide sleeve 900 fitting snugly against the outer wall of the atomizing core shell 420. Then, the liquid inlet pipe control 500 is fitted onto the outer wall of the liquid guide sleeve 900, with the inner wall of the liquid inlet pipe control 500 fitting snugly against the outer wall of the liquid guide sleeve 900. This completes the installation of the liquid inlet pipe control 500, the liquid guide sleeve 900, and the atomizing core 400, achieving an easy assembly effect. The purpose of providing the liquid guide sleeve 900 is that, in some embodiments, softer materials such as silicone can be used as the material for the liquid inlet tube control 500. This makes it difficult to form a gap 520 between the inner wall of the liquid inlet tube control 500 and the inner wall of the atomizing core shell 420 when the liquid inlet tube control 500 is sleeved outside the atomizing core shell 420. However, by sleeved with a liquid guide sleeve 900 having multiple through holes or through grooves on its side wall, a gap can be maintained between the inner wall of the liquid inlet tube control 500 and the outer wall of the atomizing core shell 420, and the atomizing liquid and gas can flow through the liquid guide sleeve 900.

[0138] In this embodiment, the thickness of the liquid guide sleeve 900 is equal to the radial dimension of the gap 520 along the liquid inlet pipe control 500. Thus, after assembling the liquid inlet pipe control 500, the liquid guide sleeve 900, and the atomizing core 400, it can be ensured that the radial dimension of the gap 520 along the liquid inlet pipe control 500 meets the conditions for forming an atomized liquid film after the gap 520 is filled with atomizing liquid (greater than or equal to 0.1 mm and less than or equal to 1.5 mm). In other words, as long as the liquid guide sleeve 900 and the liquid inlet pipe control 500 are sequentially sleeved on the outer wall of the atomizing core shell 420, the radial dimension of the gap 520 along the liquid inlet pipe control 500 can be controlled.

[0139] Of course, since the liquid guiding sleeve 900 is set inside the gap 520, in order to fill the gap 520 with atomizing liquid, as mentioned above, the sidewall of the liquid guiding sleeve 900 in this embodiment is porous, mesh or slit, etc., and is not limited here.

[0140] When the liquid guide sleeve 900 is porous, that is, through holes arranged in an array are opened on the side wall of the liquid guide sleeve 900. The more through holes there are, the greater the surface tension of the atomized liquid film formed after the through holes are filled with atomized liquid, which can better block the air in the air passage 710 from flowing towards the liquid storage cup 600.

[0141] Optionally, the material of the fluid guide sleeve 900 may be metal, silicone, or ceramic, etc., and there is no limitation on it.

[0142] Based on all the above embodiments, the material of the liquid inlet tube control 500 is metal, silicone or ceramic, etc., and is not limited here.

[0143] The reason for placing the liquid guide sleeve 900 between the atomizing core shell 420 and the liquid inlet tube control 500 is that when the material of the liquid inlet tube control 500 is silicone, the softness of silicone makes it impossible to control the size of the gap 520 between the liquid inlet tube control 500 and the outer wall of the atomizing core shell 420. In this embodiment, to ensure the size of the gap 520, the liquid guide sleeve 900 (with a thickness equal to the size of the gap 520) is placed on the outer wall of the atomizing core shell 420, and the liquid inlet tube control 500 is then placed on the liquid guide sleeve 900, thus accurately controlling the size of the gap 520. Of course, when the material of the liquid inlet tube control 500 is other types of material (such as metal, ceramic, etc.), the liquid guide sleeve 900 can also be placed on the outer wall of the atomizing core shell 420.

[0144] This application also provides an electronic atomizing device, including the atomizer in any of the above embodiments. Optionally, the electronic atomizing device is applicable to fields such as electronic cigarette atomization, medical atomization, and herbal atomization, and is not limited thereto.

[0145] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
