Description

Atomizer and electronic atomization device

Technical Field

The utility model belongs to the technical field of the electronic atomization technique and specifically relates to an atomizer and electronic atomization device are related to.

Background

The electronic atomizer generally comprises a liquid storage cup, an atomizing core, an air outlet channel, an air inlet channel, an electrode and the like. The atomizing core comprises leading liquid and heat-generating body, and the heat-generating body is used for heating atomizing liquid, leads liquid intercommunication stock solution cup and sets up the heat-generating body in the air flue to leading-in the heat-generating body from the stock solution cup with atomizing liquid. The liquid-guiding body of the atomizing core is generally made of liquid-guiding cotton or liquid-guiding ceramic and other materials.

The working principle of the atomizer is as follows: when the heating body works, the atomized liquid guided by the atomized liquid can be heated, the liquid storage cup continuously supplies the atomized liquid to the liquid guide, the liquid level is reduced along with the continuous consumption of the atomized liquid in the liquid storage cup, the air pressure in the liquid storage cup can be continuously reduced, so that the negative pressure value of the air pressure in the liquid storage cup relative to the air pressure in the air passage can be increased, when the negative pressure value is increased to a certain degree, the air pressure value of the air pressure in the air passage can exceed the resistance of the liquid guide to the external atmosphere to enter the liquid storage cup, and then the air in the air passage can pass through the liquid guide to enter the liquid storage cup, namely commonly called 'return air', so that the static balance of the air pressure between the liquid storage cup and the air passage is formed, so that the air pressure in the liquid storage cup is increased again, the air pressure in the liquid storage cup is reduced relative to the negative pressure value of the air pressure in the air passage, and a certain negative pressure is maintained in the liquid storage cup all the time, so that the atomized liquid in the liquid storage cup can not leak.

However, most atomizing cores in the market are directly communicated with liquid outlet holes of a liquid storage cup, and liquid inlet and air return of the atomizing cores in an air passage to the liquid storage cup are controlled by an atomizer mainly through resistance generated by the elasticity or porosity of liquid guide and negative pressure relative to air pressure in the air passage in the liquid storage cup, so that the problems of difficulty in blending and compromise are caused in the process of liquid inlet control and liquid leakage prevention in the using process, sometimes the liquid guide presses the liquid outlet holes tightly enough, and although gas can be well prevented from entering the liquid storage cup, the problems that the resistance is too large and the atomizing liquid is difficult to flow into the air passage are easily caused; and sometimes if the liquid guiding hole is too loose when the liquid guiding hole is pressed, the liquid storage cup can return air normally, but the liquid leakage is easy to happen.

Specifically, the control of liquid inlet and leakage by only the elasticity and porosity of the liquid is liable to have the following problems:

1. the lateral wall of an atomizing core support of the atomizing core is generally provided with more than two liquid inlet holes, the liquid inlet holes are communicated with the liquid outlet holes on the liquid storage cup, if the atomizer is in an abnormal use posture, if the atomizer is horizontally placed, obliquely placed or inverted, the liquid inlet holes arranged on the atomizing core support can be exposed above the liquid level of atomized liquid, at the moment, the gravity of the atomized liquid is reduced or completely becomes zero, and the resistance generated by liquid guiding is reduced, so that the static balance of air pressure between the liquid storage cup and the air passage before is broken, the air pressure in the air passage is far greater than the air pressure in the liquid storage cup, then the air in the air passage enters the liquid storage cup through the liquid guiding and the liquid inlet holes, the air pressure in the liquid storage cup is kept level with the atmospheric pressure in the air passage, namely, the liquid storage cup is reduced relative to the negative pressure of the air passage or even nearly zero, so that the atomized liquid in the liquid storage cup flows to the air passage through the liquid guiding, and liquid leakage is caused. In addition, when the atomized liquid in the liquid storage cup is reduced to a certain amount, the air pressure in the liquid storage cup is reduced, so that the negative pressure value of the liquid storage cup relative to the air passage is increased, and the air in the air passage can enter the liquid storage cup through the liquid guide hole and the liquid inlet hole to cause liquid leakage.

2. When the atomizer adopts the water-based atomized liquid, the water-based atomized liquid has the characteristic of large surface tension, so that in the process of conducting the water-based atomized liquid to the liquid guide body, more energy is needed to destroy the water molecular bonds in the water-based atomized liquid, the surface tension of the water-based atomized liquid is too large, the water-based atomized liquid is not easily conducted to the liquid guide body, and the phenomenon of dry burning due to unsmooth liquid supply of an atomizing core is easily caused; when the water-based atomization liquid is not used, the water-based atomization liquid has the characteristic of low viscosity, and the water-based atomization liquid is easy to leak into an air passage, so that liquid leakage is caused.

3. Whether feed liquor hole on the atomizing core support soaks in the atomized liquid, because height-hour is low when the atomized liquid in the stock solution cup, consequently has the error in visual sense at some times, leads to probably to appear under the state that lacks the atomized liquid, and the user uses the atomizer to take place the condition of dry combustion method.

Further, as shown in FIGS. 3-4 and 7-8, a liquid injection hole 310 is formed in the base 300, and the atomized liquid from the outside is injected into the liquid storage cup 600 through the liquid injection hole 310. The base 300 is further provided with a liquid injection hole plug 320, and the liquid injection hole plug 320 is arranged in the liquid injection hole 310 to prevent the atomized liquid in the liquid storage cup 600 from flowing out of the liquid injection hole 320 to the outside. When the atomized liquid needs to be added, the liquid injection hole plug 320 is pulled out, and the liquid is injected into the liquid storage cup 600.

Further, in order to seal the gap between the atomizing core housing 420 and the sleeve 200, the atomizer of the present embodiment is further provided with a sealing ring 800 at the junction between the atomizing core housing 420 and the sleeve 200. Among them, the sealing ring 800 has two functions: one function is that when the liquid level of the atomized liquid in the liquid storage cup 600 exceeds the joint between the atomizing core shell 420 and the sleeve 200, the atomized liquid in the liquid storage cup 600 can be prevented from leaking into the air channel 710 from the joint between the atomizing core shell 420 and the sleeve 200, namely, the atomizer is prevented from leaking liquid; the other function is that when the liquid level of the atomized liquid in the liquid storage cup 600 is lower than the connection between the atomizing core housing 420 and the sleeve 200, the air in the air passage 710 can be prevented from entering the liquid storage cup 600 from the connection between the atomizing core housing 420 and the sleeve 200, so that the phenomenon that the atomized liquid in the liquid storage cup 600 flows into the air passage 710 through the liquid inlet hole 410 and the liquid guide body 430 to cause liquid leakage of the atomizer due to the fact that the air pressure in the liquid storage cup 600 is equal to the atmospheric pressure in the air passage 710 (that is, the negative pressure of the liquid storage cup 600 relative to the air passage 710 is reduced) can be prevented. That is, whether the atomized liquid in the reservoir 600 is sufficient or not, the seal ring 800 disposed between the atomizing core housing 420 and the sleeve 200 can further ensure that the atomized liquid in the reservoir 600 does not leak from the connection between the atomizing core housing 420 and the sleeve 200 or from the liquid inlet 410.

It should be noted that the atomizing core 400 in the embodiment of the present invention does not include only the atomizing core case 420, the liquid guiding body 430, the heating body and the atomizing core holder 440, but also includes the structure of the electrode, the insulating holder, etc., that is, the structure of the atomizing core 400 is not modified in the embodiment of the present invention, that is, the atomizing core 400 is not limited to the structure of the atomizing core 400.

In this embodiment, the liquid inlet pipe control 500 is sleeved on the periphery of the atomizing core housing 420 and is located at the bottom of the liquid storage cup 600. The bottom of the liquid storage cup 600 is the side of the liquid storage cup 600 close to the base 300, i.e. the liquid inlet pipe control 500 is arranged on the side of the liquid storage cup 600 close to the base 300 and connected with the base 300. Of course, the liquid inlet pipe control 500 may also be connected to the atomizing core holder 440, and is not limited herein.

Specifically, a plurality of capillary portions 510 are disposed at least in a partial region of the sidewall of the liquid inlet pipe control 500, and the capillary portions 510 are in communication with the liquid storage cup 600. In an embodiment of the present invention, as shown in fig. 3 and fig. 4, a capillary portion 510 is disposed on a part of the sidewall of the liquid inlet pipe control 500, and the capillary portion 510 disposed on the part of the sidewall is disposed at a radial relative interval with the liquid inlet hole 410 of the liquid inlet pipe control 500 to form a gap 520. For example, the inner sidewall of the liquid inlet pipe control 500 and the liquid inlet hole 410 may be mutually staggered, and may be attached to the outer sidewall of the atomizing core housing 420, or may be arranged with a certain gap therebetween, or may further be provided with a capillary portion 510, and the capillary portion 510 may be in contact with the outer sidewall of the atomizing core housing 420, or may be arranged with a certain gap therebetween and form a gap 520, which is not limited herein.

Further, the capillary portion 510 may be disposed on all sidewalls of the liquid inlet pipe control 500, the capillary portion 510 located at the liquid inlet hole 410 is disposed opposite to the liquid inlet hole 410 to form a gap 520, and the capillary portions 510 at other positions may be disposed opposite to the outer sidewall of the atomizing core casing 420 to form the gap 520, or may be attached to the outer sidewall of the atomizing core casing 420.

It should be noted that one of the functions of the capillary portion 510 is that, because the capillary portion 510 is in a capillary structure, the capillary portion 510 can guide the atomized liquid from the liquid storage cup 600 to the capillary portion 510 through capillary action. This is as if a hair line were placed on a droplet, which is originally hemispherical, but because of the placement of a hair line, some of the liquid in the droplet will move some distance along the hair line. Due to the surface tension of the atomized liquid, especially the atomized liquid with high water content such as water-based atomized liquid, the surface tension of the atomized liquid is increased, so that the capillary portion 510 can break the surface tension of the atomized liquid, and the atomized liquid in the reservoir cup 600 is continuously guided to the capillary portion 510, then flows to the gap 520 through the capillary portion 510, and flows into the liquid inlet hole 410 of the atomizing core housing 420, and then flows into the liquid guide 430. Like this, capillary portion 510 has just played and has made the atomized liquid in the stock solution cup 600 flow into more fast more smoothly and lead in liquid 430, supply with to lead the atomizing effect of the heat-generating body heating that liquid 430 is connected, has not only prevented the dry combustion method, can continuously produce sufficient smog moreover to promote the taste of smog, promoted user's use and experienced.

In addition, it should be noted that the gap 520 has a function that, when the gap 520 is filled with the atomized liquid, due to the surface tension of the atomized liquid itself and the gap 520 has a certain narrow space, the atomized liquid forms a layer of atomized liquid film at the gap 520, so that, under the condition that the gravity of the atomized liquid itself and the air pressure in the liquid storage cup 600 are reduced, for example, when the atomizer is laid flat or turned upside down or the atomized liquid in the liquid storage cup 600 is reduced, the resistance of the external air entering the liquid storage cup 600 can be increased by the atomized liquid film, that is, the layer of atomized liquid film can block the air (i.e., the external air) in the air passage 710 from entering the liquid storage cup 600 through the liquid inlet hole 410, so as to prevent the atomized liquid in the liquid storage cup 600 from flowing into the air passage 710 through the liquid inlet hole 410 and the liquid guiding body 430 to cause liquid leakage of the atomizer due to the fact that the air pressure in the liquid storage cup 600 is equal to the atmospheric pressure in the air passage 710 (i.e., the negative pressure of the liquid storage cup 600 relative to the air passage 710 is reduced).

In this embodiment, the capillary 510 is used to guide the atomized liquid, as previously described. When the atomizer is used, when the atomized liquid in the liquid storage cup 600 is sufficient, not only the air pressure in the liquid storage cup 600 is larger than the air pressure in the air passage 710, but also the atomized liquid in the liquid storage cup 600 can rapidly flow through the capillary part 510 and enter the gap 520 due to the capillary action of the capillary part 510 and the large gravity of the atomized liquid in the liquid storage cup 600, in this case, even if an atomized liquid film is formed at the gap 520, the atomized liquid can continuously flow into the gap 520 from the liquid storage cup 600, that is, the atomized liquid can also break the surface tension of the atomized liquid film and smoothly flow to the liquid guiding body 430 and the heating body, so that the heating body heats and atomizes the atomized liquid. That is to say, when the atomizing liquid in the stock solution cup 600 is sufficient, the atomizing liquid can flow to the position of heat-generating body through capillary portion 510 more fast, more in a large number and heat the atomizing, consequently can continuously produce a large amount of smog, not only can prevent dry combustion method, can promote user's use moreover and experience and inhale the taste.

When the atomizer is in a flat, inclined or inverted state or after the atomized liquid in the liquid storage cup 600 is reduced, because the air pressure in the liquid storage cup 600 is reduced and the weight of the atomized liquid in the liquid storage cup 600 is reduced, the atomized liquid film formed by the surface tension of the atomized liquid in the gap 520 formed between the capillary part 510 and the liquid inlet hole 410 can be prevented from entering the liquid storage cup 600 through the liquid guiding 430 and the liquid inlet hole 410 when the atomized liquid in the liquid storage cup 600 is reduced to a certain amount, namely the air pressure in the liquid storage cup 600 is reduced (the negative pressure value of the liquid storage cup 600 relative to the air passage 710 is also increased), thereby ensuring that the air pressure in the liquid storage cup 600 is not almost equal to the atmospheric pressure in the air passage 710 and liquid leakage occurs. That is, when the atomized liquid is in a flat, inclined, or inverted state, or after the atomized liquid in the liquid storage cup 600 is reduced, the atomized liquid film formed at the gap 520 can play its role, so as to prevent the air in the air channel 710 from entering the liquid storage cup 600 through the liquid guiding 430 and the liquid inlet hole 410, and prevent the liquid leakage caused by the nearly even internal air pressure of the liquid storage cup 600 and the atmospheric pressure in the air channel 710.

Moreover, the capillary portion 510 also has a function of storing a part of the atomized liquid in the capillary portion 510, so that even if the liquid in the liquid storage cup 600 is insufficient, the capillary portion 510 can provide the atomized liquid stored in the liquid guide 430 and the heating element to the heating element when the user uses the atomizer, thereby temporarily alleviating the occurrence of dry burning.

The operation and the operation principle of the capillary 510 and the gap 520 in the embodiment of the present invention are explained in detail above. The embodiments of the present invention will be described in detail based on the above description.

In some structural designs of the atomizer that the embodiment of the utility model provides, please refer to fig. 2 to 5, at least some regions of the lateral wall of feed liquor pipe control 500 are provided with a plurality of capillary portions 510 at intervals each other, and capillary portion 510 sets up and is formed with clearance 520 at feed liquor pipe control 500's footpath relative interval with feed liquor hole 410 at least, because of capillary 510's capillary action, even under the surface tension of atomized liquid is great condition, atomized liquid in the stock solution cup 600 also can flow into in clearance 520 along capillary portion 510. And, the atomized liquid entering the gap 520 between the capillary part 510 and the liquid inlet 410 forms an atomized liquid film at the gap 520 again due to the surface tension of the atomized liquid itself. Like this, under the circumstances of the gravity of atomized liquid and the atmospheric pressure in the stock solution cup 600 reduce, for example the atomizer is kept flat, put to one side, or when inverting, or the atomized liquid in the stock solution cup 600 reduces the back, can increase the resistance that external gas enters into the stock solution cup 600 through the atomized liquid film, block the air in the air flue through the atomized liquid film promptly and pass through and lead liquid 430, feed liquor hole 410 enters into the stock solution cup 600 in, thereby can guarantee that the atmospheric pressure in the stock solution cup 600 maintains abundant negative pressure state for the atmospheric pressure in the air flue, and then make the atomized liquid in the stock solution cup 600 be difficult to pass through feed liquor hole 410, lead liquid 430 inflow air flue, avoid the atomizer to appear the weeping.

In addition, when the atomizer adopted water base atomized liquid, the embodiment of the present invention provides a capillary portion 510 through setting up on feed liquor pipe control 500 for water base atomized liquid in the liquid storage cup 600 can destroy the surface tension of water base atomized liquid through the capillary action of capillary portion 510, make water base atomized liquid enter into in the clearance 520 along capillary portion 510. And when the water base atomized liquid in the liquid storage cup 600 is sufficient, the water base atomized liquid can destroy the water base atomized liquid film formed in the gap 520 through the gravity of the water base atomized liquid and the large air pressure in the liquid storage cup 600, that is, the large surface tension of the water molecular bond in the water base atomized liquid can be destroyed, so that the water base atomized liquid can be smoothly conducted to the liquid guiding body 430 through the liquid inlet hole 410 and then heated and atomized through the heating body, and the dry burning is avoided.

And, the embodiment of the utility model provides a through set up capillary portion 510 at least with feed liquor hole 410 at feed liquor pipe control 500 footpath relative separation and be formed with clearance 520 to and form water base atomizing liquid film after being full of water base atomizing liquid in capillary portion 510 and clearance 520, can prevent because water base atomizing liquid viscosity is low, even when the atomizer is in non-user state, water base atomizing liquid is also difficult to leak in the air flue, thereby can prevent the emergence of weeping. Further, as mentioned before, because the utility model discloses in the embodiment capillary portion 510 all communicates with stock solution cup 600, and can store some atomized liquid in the capillary portion 510, even do not have atomized liquid to flow in capillary portion 510 continuously in short period like this, the atomized liquid that stores in the capillary portion 510 also can flow to heat the atomizing to heat body department through feed liquor hole 410, lead liquid 430, thereby when having avoided oweing liquid, for example the user directly perceived visual error (think that the atomized liquid is sufficient promptly and owe liquid in fact) leads to lacking the atomized liquid and take place the phenomenon of dry combustion method when the atomizer uses, the life of atomizer has been prolonged.

The sealing ring 800 is arranged between the atomizing core shell 420 and the sleeve 200, so that when the liquid level of the atomized liquid in the liquid storage cup 600 exceeds the joint between the atomizing core shell 420 and the sleeve 200, the atomized liquid in the liquid storage cup 600 can be prevented from leaking into the air passage 710 from the joint between the atomizing core shell 420 and the sleeve 200, namely, the atomizer is prevented from leaking liquid; or, when the liquid level of the atomized liquid in the liquid storage cup 600 is lower than the connection between the atomizing core housing 420 and the sleeve 200, the air in the air passage 710 can be prevented from entering the liquid storage cup 600 from the connection between the atomizing core housing 420 and the sleeve 200, so that the occurrence of liquid leakage of the atomizer due to the fact that the air pressure in the liquid storage cup 600 is equal to the atmospheric pressure in the air passage 710 (that is, the negative pressure of the liquid storage cup 600 relative to the air passage 710 is reduced) and the atomized liquid in the liquid storage cup 600 flows into the air passage through the liquid inlet hole 410 and the liquid guide body 430 can be prevented.

In this embodiment, the liquid inlet pipe control 500 may be a hollow cylinder, that is, the liquid inlet pipe control 500 is a hollow cylinder formed by enclosing, and the liquid inlet pipe control 500 of the hollow cylinder is sleeved on the periphery of the atomizing core housing 420 close to the base 300. Wherein, capillary 510 is set up on the inside wall of feed liquor pipe control 500.

The area of the inner sidewall of the liquid inlet pipe control 500, which is dislocated from the liquid inlet hole 410, may be disposed at intervals or may be disposed in a fitting manner with respect to the outer sidewall of the atomizing core housing 420, and a continuous or discontinuous capillary portion 510 (not shown) may be disposed on the inner sidewall, which, of course, may not be processed; alternatively, the inner sidewall of the inlet pipe control 500 may be provided with a hollowed-out portion (as shown in fig. 3-5) in a position offset from the inlet hole 410, which is not limited herein.

Further, the capillary portion 510 may be a capillary groove that is formed on the inner sidewall of the liquid inlet pipe control 500 from top to bottom along the length direction of the liquid inlet pipe control 500, and the capillary grooves are arranged at intervals along the circumferential direction of the liquid inlet pipe control 500. Because feed liquor pipe controlling part 500 is the cavity barrel, and the length direction of feed liquor pipe controlling part 500 is the axial direction or the direction of height of feed liquor pipe controlling part 500 promptly, that is to say, the capillary groove runs through the inside wall of locating feed liquor pipe controlling part 500 along the axial direction or the direction of height of feed liquor pipe controlling part 500, and this moment, the capillary groove does not run through the lateral wall of feed liquor pipe controlling part 500. In other words, the capillary groove is disposed through the inner sidewall of the liquid inlet pipe control 500 from top to bottom along the length direction of the liquid inlet pipe control 500.

Specifically, the outer sidewall of the liquid inlet pipe control 500 may be spaced apart from the inner sidewall of the housing 100 (as shown in fig. 2), and since the liquid inlet pipe control 500 is located at the bottom of the liquid storage cup 600 and the sidewall of the liquid inlet pipe control 500 is provided with the capillary portion 510, the atomized liquid in the liquid storage cup 600 is guided into the gap 520 along the capillary portion 510, so that the capillary portion 510 and the gap 520 are both filled with the atomized liquid. In addition, the outer sidewall of the liquid inlet pipe control 500 may be abutted against the inner sidewall of the housing 100 (not shown), and the liquid inlet pipe control 500 is still located at the bottom of the liquid storage cup 600, at this time, the atomized liquid in the liquid storage cup 600 may also be guided into the gap 520 along the capillary portion 510, so that the capillary portion 510 and the gap 520 are filled with the atomized liquid.

When the outer sidewall of the liquid inlet pipe control 500 is abutted against the inner sidewall of the housing 100, in order to prevent the liquid inlet pipe control 500 from blocking the external atomized liquid from being injected into the liquid storage cup 600 from the liquid injection hole 310, in this embodiment, a liquid passing hole 530 (refer to fig. 9, the position of the liquid passing hole is staggered from the capillary 510) is further formed in the liquid inlet pipe control 500 corresponding to the liquid injection hole 310, and the liquid passing hole 530 is used for communicating the liquid injection hole 310 with the liquid storage cup 600.

In this embodiment, the groove width of the capillary groove may be set to 0.1mm to 1.2mm. Further, the width of the capillary groove is set to be 0.2 mm-0.5 mm.

Further, the groove width of the capillary groove is set to be 0.3mm to 0.4mm.

It should be noted that, since the capillary groove can store the atomized liquid, when the atomizer is in an inverted state, the atomized liquid stored in the capillary groove can still be retained in the capillary groove due to the capillary action of the capillary groove, and will not flow back into the liquid storage cup 600. When the atomizing liquid is insufficient in the liquid storage cup 600, the atomizing liquid stored in the capillary groove can be heated and atomized through the heating body after being guided into the liquid guiding body 430 through the liquid inlet hole 410, and dry burning is prevented.

In this embodiment, the capillary groove is still arranged in guiding the atomized liquid to flow into clearance 520, the atomized liquid in the stock solution cup 600 can flow into clearance 520 department along the capillary groove promptly, form the atomized liquid film after being filled with the atomized liquid in clearance 520, the atomized liquid film in clearance 520 reduces the back when stock solution cup 600, the atomized liquid film in clearance 520 can prevent to be greater than the pressure in the stock solution cup 600 because of external atmospheric pressure, gas gets into stock solution cup 600 through feed liquor hole 410 and leads to the negative pressure reduction in the stock solution cup 600, make the atomized liquid flow to lead liquid 430 from the capillary groove, thereby the phenomenon of weeping takes place.

When the atomizer is used and the atomized liquid in the liquid storage cup 600 is sufficient, a negative pressure is formed in the air passage 710, namely the external atmospheric pressure in the air passage 710 is smaller than the sum of the atmospheric pressure in the liquid storage cup 600 and the gravity of the atomized liquid, so that the atomized liquid in the liquid storage cup 600 flows into the gap 520 along the capillary groove and breaks through the surface tension of the atomized liquid film in the gap 520, and flows into the liquid guide body 430 through the liquid inlet hole 410, and then is heated and atomized through the heating body. When the atomizer is used and the atomized liquid in the liquid storage cup 600 is insufficient, the capillary groove can provide the atomized liquid stored in the liquid guide 430 and the heating element, and the dry burning phenomenon can be temporarily relieved.

Certainly, in order to make more atomizing liquid of capillary groove storage and make more unobstructed near the heat-generating body that flows in air flue 710 after the atomizing liquid flows into the capillary groove, the vertical depth of capillary groove in this embodiment can be greater than 0.5mm, specifically can set up according to the size of stock solution cup 600, and the vertical depth of capillary groove is big more, and its stock solution is more, and the stock solution effect is also better.

Optionally, the capillary groove has a longitudinal depth of 2mm to 8mm.

Since the capillary grooves can store the atomized liquid, when the atomizer is used, the atomized liquid in the liquid storage cup 600 flows into the gap 520 along the capillary grooves and flows toward the liquid inlet hole 410, thereby damaging the atomized liquid film formed in the gap 520. In order to enable the atomized liquid in the liquid storage cup 600 to smoothly flow into the gap 520 along the capillary grooves, in the embodiment, the distance between two adjacent capillary grooves is 0.1mm to 2.0mm, that is, the distance between the capillary grooves is reasonably distributed, so as to achieve the effect of smooth liquid guiding.

Furthermore, the distance between two adjacent capillary grooves is 0.2 mm-0.5 mm, so that the liquid can be guided more smoothly, and a better liquid guiding effect is achieved.

In this embodiment, the capillary 510 and the liquid inlet hole 410 are spaced apart from each other to form a gap 520, and in order to fill the gap 520 with the atomized liquid and then form an atomized liquid film, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.1mm to 1.5mm. If the radial size of the gap 520 along the liquid inlet pipe control 500 is less than 0.1mm, the process is difficult to realize and liquid cannot be easily guided; if the size of the gap 520 in the radial direction of the liquid inlet pipe control 500 is greater than 1.5mm, the atomized liquid film is difficult to form after the gap 520 is filled with the atomized liquid.

Further, the radial dimension of the gap 520 along the liquid inlet pipe control 500 is 0.2 mm-0.8 mm.

Further, the gap 520 has a size of 0.3mm to 0.5mm in the radial direction of the liquid inlet pipe control 500. Wherein, the smaller the radial size of clearance 520 along feed liquor pipe control 500, the greater the surface tension of the atomized liquid film that forms, gaseous being difficult to destroy the atomized liquid film more promptly and entering into the stock solution cup 600 in, avoid the atomized liquid in the stock solution cup 600 to appear leaking.

In this embodiment, the radial dimension of the gap 520 along the liquid inlet pipe control 500 may be equal in the circumferential direction of the whole liquid inlet pipe control 500, or the radial dimension of the gap 520 along the liquid inlet pipe control 500 may be gradually increased or decreased in the direction toward the sleeve 200, as long as it is ensured that the radial dimension of the gap 520 along the liquid inlet pipe control 500 satisfies the condition that the atomized liquid film can be formed after the gap 520 is filled with the atomized liquid.

The capillary groove is a straight groove, a curved groove, a wavy groove or an irregular groove and the like. Of course, in other embodiments, the capillary groove may be other types of grooves, such as: the combination of the straight groove and the curved groove, the combination of the straight groove and the wave-shaped groove, and the like are not limited herein.

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 portion 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, so as to ensure that the capillary portion 510 is at least spaced from the liquid inlet hole 410 and forms the gap 520.

Referring to fig. 6-9, fig. 6-9 are schematic views of other structural designs according to embodiments of the present invention. The capillary part 510 is disposed on the entire inner sidewall of the liquid inlet pipe control 500, and as mentioned above, the atomized liquid in the liquid storage cup 600 can be guided to flow into the capillary part 510 rapidly by the capillary action of the capillary part 510. The capillary 510 is spaced from the outer sidewall of the atomizing core housing 420 and the liquid inlet hole 410 in the radial direction of the liquid inlet pipe control 500 to form a gap 520. That is between the lateral wall of capillary 510 and atomizing core casing 420, homogeneous phase is to the interval setting and is formed with clearance 520 between capillary 510 and the feed liquor hole 410, so that when being full of the atomized liquid in clearance 520, can form the atomized liquid film between capillary 510 and feed liquor hole 410, this atomized liquid film is used for increasing the resistance that the air entered into stock solution cup 600, block the air in the air flue through the atomized liquid film promptly and enter into stock solution cup 600 in, thereby can guarantee that stock solution cup 600's inside atmospheric pressure can not keep level with the air atmosphere in the air flue, and then avoid the atomizer weeping to appear.

Further, as described in the embodiments of fig. 2 to fig. 5, the capillary portion 510 may be a capillary groove that is formed on the inner sidewall of the liquid inlet pipe control 500 from top to bottom along the length direction of the liquid inlet pipe control 500, and the capillary grooves are arranged at intervals along the circumferential direction of the liquid inlet pipe control 500, which is not described herein again.

In this embodiment, the outer sidewall of the liquid inlet pipe control 500 abuts against the inner sidewall of the housing 100, and the liquid inlet pipe control 500 is still located at the bottom of the liquid storage cup 600, i.e. the atomized liquid in the liquid storage cup 600 is guided into the capillary portion 510 and the gap 520, so that the capillary portion 510 and the gap 520 are filled with the atomized liquid. The groove width of the capillary groove, the longitudinal depth of the capillary groove, the distance between two adjacent capillary grooves, and the radial dimension of the gap 520 along the liquid inlet pipe control 500 are all the same as those described above, and are not described in detail herein.

As shown in fig. 10 and 11, the atomizer of the present invention may further include a liquid guiding sleeve 900, which is a hollow cylinder and is disposed in the gap 520 between the capillary portion 510 and the outer sidewall of the atomizing cartridge 420. And in the assembling process, can overlap the drain cover 900 earlier and establish on the lateral wall of atomizing core shell 420 for the inside wall of drain cover 900 and the lateral wall of atomizing core shell 420 laminate the setting each other, then overlap feed liquor pipe control 500 cover on the lateral wall of drain cover 900, make the inside wall of feed liquor pipe control 500 laminate the setting with the lateral wall of drain cover 900 each other, thereby accomplish the installation between feed liquor pipe control 500, drain cover and the atomizing core 400, reach the effect of easily assembling. The purpose of setting up drain cover 900 is because can regard as the material of feed liquor pipe controlling part 500 with softer materials such as silica gel in some embodiments, when leading to feed liquor pipe controlling part 500 cover to establish outside atomizing core shell 420, be difficult to form clearance 520 between feed liquor pipe controlling part 500 inner wall and atomizing core shell 420 inner wall, and the cover establishes the drain cover 900 that the lateral wall was equipped with a plurality of through-holes or leads to the groove, just can keep the clearance between feed liquor pipe controlling part 500 inner wall and atomizing core shell 420 outer wall, and enable atomized liquid and gaseous through leading the formation of liquid cover 900 and circulate.

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

Of course, the liquid guide sleeve 900 is disposed in the gap 520, that is, in order to fill the gap 520 with the atomized liquid, as described above, the sidewall of the liquid guide sleeve 900 in the present embodiment is porous, mesh, slit, or the like, and is not limited thereto.

When the liquid guiding sleeve 900 is porous, that is, the side wall of the liquid guiding sleeve 900 is provided with through holes arranged in an array manner, wherein the more the number of the through holes is, the greater the surface tension of an atomized liquid film formed after the through holes are filled with the atomized liquid is, and the air in the air passage 710 can be better prevented from flowing towards the direction of the liquid storage cup 600.

Optionally, the material of the drainage sleeve 900 is metal, silicon, ceramic, or the like, which is not limited herein.

Based on all the above embodiments, the material of the liquid inlet pipe control 500 is metal, silica gel, or ceramic, and is not limited herein.

The liquid guide sleeve 900 is sleeved between the atomizing core casing 420 and the liquid inlet pipe control 500, because the liquid inlet pipe control 500 is made of silica gel, the material of the silica gel is soft, so that when the liquid inlet pipe control 500 is arranged on the periphery of the atomizing core 400, the size of the gap 520 between the liquid inlet pipe control 500 and the outer side wall of the atomizing core casing 420 cannot be controlled, at this time, in order to ensure the size of the gap 520, the liquid guide sleeve 900 (the thickness of which is equal to the size of the gap 520) is sleeved on the outer side wall of the atomizing core casing 420 in the embodiment, and the liquid guide sleeve 900 is sleeved with the liquid inlet pipe control 500, so that the size of the gap 520 can be accurately controlled. Of course, when the material of the liquid inlet pipe control 500 is other types of materials (such as metal, ceramic, etc.), the liquid guiding sleeve 900 may be sleeved on the outer sidewall of the atomizing core casing 420.

The utility model also provides an electronic atomization device, including the atomizer in above-mentioned arbitrary one embodiment. Alternatively, the electronic atomization device is suitable for the fields of electronic atomization, medical atomization, herbal atomization, and the like, and is not limited herein.
