Description

Technical Field

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

[0002] Electronic atomizing devices utilize the thermal effect of electronic heating elements to heat and atomize an atomizing substrate, thereby generating volatile substances such as aerosols. An electronic atomizing device includes an atomizer, which contains an atomizing component and stores the atomizing substrate. The atomizing component heats the atomizing substrate to produce an aerosol. However, the atomizer has a limited volume, resulting in a small mass of atomizing substrate that can be stored. Therefore, frequent atomizer replacements or replenishment of the atomizing substrate are necessary.

[0003] In related technologies, a liquid storage bottle (or liquid storage container) is connected to the atomizer to replenish the atomizing matrix, thereby solving the problem of insufficient atomizing matrix. However, in this device, since the atomizing matrix is ​​replenished through a single channel between the liquid storage bottle and the atomizer, a state of pressure balance between the liquid storage bottle and the external environment can easily occur. This can lead to the liquid storage bottle being unable to continue supplying liquid to the atomizer, ultimately resulting in wick clogging due to insufficient liquid supply. At the same time, the remaining atomizing matrix in the liquid storage bottle cannot be supplied to the atomizer, which can also easily lead to waste. Utility Model Content

[0036] It should be further noted that the atomizing matrix in this article is a liquid matrix.

[0037] This application provides an electronic atomizing device capable of heating the aforementioned atomizing matrix to form an aerosol for user use.

[0038] Please see Figures 1 to 8 The electronic atomizing device includes an atomizer 100, a liquid reservoir 200, and a power supply assembly 300. The atomizer 100 includes a first housing 110 and an atomizing assembly 120. The first housing 110 has a first liquid reservoir 111 for storing the atomizing matrix. The atomizing assembly 120 is disposed within the first housing 110 and communicates with the first liquid reservoir 111 for heating the atomizing matrix to form an aerosol. The exterior of the first housing 110 has two liquid inlet channels 130 along a first direction Y, which communicate with the first liquid reservoir 111. The liquid reservoir 200 includes a second housing 200. 10. The second housing 210 is provided with a second liquid storage chamber 211, which is used to store the atomizing matrix; the exterior of the second housing 210 is provided with two liquid supply channels 220 along the first direction Y, which are connected to the second liquid storage chamber 211; the power supply component 300 is used to provide power to the atomizing component 120; the atomizer 100 and the liquid storage 200 are detachably connected. When the atomizer 100 is connected to the liquid storage 200, the liquid inlet channel 130 is connected to the liquid supply channel 220 in a one-to-one correspondence, so that the atomizing matrix in the second liquid storage chamber 211 can be replenished to the first liquid storage chamber 111.

[0039] By providing the reservoir 200, the atomizing matrix can be replenished into the atomizer 100, overcoming the small capacity limitation of traditional atomizers 100 and improving the battery life and lifespan of the electronic atomization device. The reservoir 200 and the atomizer 100 are two independent structures. The first housing 110 and the second housing 210 are also independent of each other. The first housing 110 forms the overall appearance of the atomizer 100, and its interior provides space for assembling the atomizer 100 and also forms the first reservoir 111, used for directly storing the atomizing matrix or storing intermediate media containing the atomizing matrix (such as reservoir cotton). The second housing 210 forms the overall appearance of the reservoir 200, and its interior forms the second reservoir 211, used for storing the direct atomizing matrix.

[0040] The liquid inlet channel 130 is located on one side of the first housing 110, with one end penetrating through the first housing 110 and communicating with the first liquid storage chamber 111 inside it, while the other end protrudes from the first housing 110. The liquid inlet channel 130 can be integral with the first housing 110 or detachably connected to it. When connecting the liquid reservoir 200 and the atomizer 100, the liquid inlet channel 130 is installed between the liquid reservoir 200 and the atomizer 100. The liquid inlet channel 130 can be inserted into the liquid supply channel 220 to achieve liquid circuit communication. When not in use, the liquid inlet channel 130 can be disassembled for easy storage or cleaning. The liquid supply channel 220 is located on the second housing 210 and penetrates through the second housing 210, communicating with the second liquid storage chamber 211.

[0041] In some embodiments, the first liquid storage chamber 111 is provided with a liquid inlet, and one end of the liquid inlet channel 130 can be detachably connected to the liquid inlet.

[0042] When a single liquid inlet channel 130 is set, the liquid reservoir 200 may be unable to continuously supply liquid to the atomizer 100 due to the imbalance of internal and external air pressure, resulting in insufficient replenishment of atomizing matrix, which may easily cause the risk of caking. It also means that when the liquid level is lower than the liquid inlet channel 130, the remaining atomizing matrix is ​​wasted.

[0043] This application provides two liquid inlet channels 130, which are arranged side by side along a first direction Y, which is the vertical direction when the electronic atomizing device is in use. The two liquid inlet channels 130 are arranged vertically, and the inside of the liquid reservoir 200 is also connected to the outside. When supplying liquid, the pressure of the upper liquid inlet channel 130 is greater than that of the lower liquid inlet channel 130. The pressure difference is used to guide the atomizing matrix through the lower liquid inlet channel 130 into the first liquid reservoir 111, which effectively ensures the continuous replenishment of the atomizing matrix, avoids the occurrence of clogging, and improves the service life and endurance of the electronic atomizing device.

[0044] Correspondingly, two liquid supply channels 220 are also provided, which are also arranged vertically along the first direction Y (vertical direction) and correspond to the position of the liquid inlet channel 130. The liquid inlet channel 130 can be recessed on the second housing 210 so that when the first housing 110 and the second housing 210 are connected, there is no protruding area on their connecting surface, which increases the contact area and reduces the space occupied.

[0045] In this article, the second direction X is the assembly direction of the atomizer 100 and the reservoir 200. When in use, it is a horizontal direction perpendicular to the vertical direction, which facilitates the disassembly and assembly of the atomizer 100 and the reservoir 200. The liquid inlet channel 130 extends along the second direction X, which can also prevent the atomizing matrix from leaking through the liquid inlet channel 130 under the action of gravity during disassembly or installation.

[0046] Please see Figure 2 and Figure 3 In some embodiments, the reservoir 200 and the atomizer 100 are arranged side by side along the second direction X, and the second direction X and the first direction Y are perpendicular to each other; the reservoir 200 and the atomizer 100 can be separated or assembled along the second direction X. During the assembly process, the liquid inlet channel 130 extending along the second direction X can be conveniently connected to the liquid supply channel 220.

[0047] Please see Figure 4 and Figure 5 In some embodiments, the first housing 110 is provided with a docking groove 112, and the second housing 210 is provided with a docking portion 212. The docking portion 212 protrudes in a direction away from the second housing 210 and is detachably disposed within the docking groove 112. Specifically, both the docking portion 212 and the docking groove 112 are oriented towards the second direction X. The docking portion 212 and the docking groove 112 are matched to achieve an effective connection between the atomizer 100 and the liquid reservoir 200. Of course, in other embodiments, the positions of the docking portion 212 and the docking groove 112 can be interchanged.

[0048] In some embodiments, the liquid supply channel 220 is disposed on the docking portion 212, and the liquid inlet channel 130 protrudes from the docking groove 112 in a direction away from the first housing 110. During assembly, the liquid inlet channel 130 is directly connected to the liquid supply channel 220 and the second liquid storage chamber 211.

[0049] In some embodiments, the reservoir 200 further includes a seal 230 for blocking the liquid supply channel 220; when the atomizer 100 is connected to the reservoir 200, the liquid inlet channel 130 punctures the seal and communicates with the liquid supply channel 220.

[0050] In some embodiments, two seals 230 are provided, and are provided one-to-one with two liquid supply channels 220. The two seals 230 are connected as an integral structure for easy installation.

[0051] In some embodiments, the sealing element is made of elastic sealing silicone, a readily available material with good elasticity and sealing performance.

[0052] Please see Figure 6 In some embodiments, the seal 230 includes two elastic arms 231 and a thinning portion 232. The two elastic arms 231 are symmetrically arranged on both sides of the thinning portion 232. The thinning portion 232 helps to reduce the difficulty of puncturing the seal 230, thereby improving the assembly efficiency of the electronic atomizing device. The elastic arms 231 can seal and wrap the liquid inlet channel 130, preventing leakage during the liquid supply process.

[0053] Please see Figure 7 In some embodiments, the liquid inlet channel 130 includes a conical puncture portion 131. The puncture portion 131 can reduce the contact area with the seal 230, thereby increasing the pressure and helping to puncture the seal 230 with less effort during assembly, so as to achieve the connection between the liquid supply channel 220 and the liquid inlet channel 130.

[0054] In some embodiments, the distance between the two inlet channels 130 or the two supply channels 220 in the first direction Y is 0.5mm-50mm, which can effectively ensure that the pressure difference completely guides the atomized matrix in the reservoir 200 into the first reservoir chamber 111 along the inlet channel 130. Optionally, the distance between the two inlet channels 130 or the two supply channels 220 in the first direction Y is 0.5mm, 1mm, 5mm, 10mm, 20mm, 30mm, 40mm or 50mm.

[0055] In some embodiments, a first magnetic member 113 is provided on the first housing 110 and a second magnetic member 213 is provided on the second housing 210. The first magnetic member 113 is used to magnetically connect with the second magnetic member 213 so that the atomizer 100 and the liquid reservoir 200 can be detachably connected.

[0056] In other embodiments, the atomizer 100 and the reservoir 200 may also be detachably connected by means of threads, adhesive, plugs or snaps.

[0057] In some embodiments, the power supply assembly 300 and the liquid reservoir 200 are arranged side by side along a first direction Y, the second housing 210 is provided with a first connecting portion, the power supply assembly 300 is provided with a second connecting portion, and the first connecting portion and the second connecting portion are detachably connected.

[0058] In some embodiments, the first connecting portion is a connecting protrusion, and the second connecting portion is a connecting groove. The connecting groove and the connecting protrusion cooperate to achieve a detachable connection between the power supply component 300 and the reservoir 200. Specifically, the connecting groove can be formed by a vertical recess in the second housing 210, and the connecting protrusion can be formed by a vertical protrusion in the power supply component 300. Of course, in other embodiments, the positions of the connecting protrusion and the connecting groove can be interchanged.

[0059] In some embodiments, the power supply component 300 is detachably connected to the atomizer 100, and the power supply component 300 and the atomizer 100 are arranged sequentially along the second direction X. The power supply component 300 is provided with a conductive part for electrical connection with the atomizer component 120. This also helps to divide the electronic atomizing device into three independent structures, namely the power supply component 300, the liquid reservoir 200 and the atomizer 100, so as to facilitate the individual replacement of each structure, thereby reducing the cost of using the electronic atomizing device. It also facilitates free combination with different models of various structures to achieve different functions. For example, the atomizer 100 can be selected from different models with a single heating element or two or more heating elements to meet the user's different atomization volume requirements.

[0060] In some embodiments, the power supply assembly 300 and the atomizer 100 may be connected using the magnetic attraction of an electromagnetic element.

[0061] In other embodiments, the power supply component 300 and the atomizer 100 may also be an integral structure. The power supply component 300 is disposed on one side of the atomizer 100 along the second direction X, and the atomizer 100 and the power supply component 300 form an installation space to facilitate the installation of the liquid reservoir 200.

[0062] Please continue reading. Figure 7 In some embodiments, at least one capillary channel 132 is provided on the inner wall of the liquid inlet channel 130. Because multiple capillary channels 132 are provided on the inner wall of the liquid inlet channel 130, air bubbles cannot be formed on the inner wall of the liquid inlet channel 130 to block the liquid inlet channel 130, thus ensuring smooth and stable liquid supply to the liquid inlet channel 130. At the same time, under the capillary effect of the capillary channel 132, the flow of the atomizing matrix can be effectively guided, and the gas inside the liquid inlet channel 130 can be discharged so that the gas passes quickly along the capillary channel 132, thereby promoting the smoothness of the flow of the atomizing matrix, ensuring the stability of the liquid supply to the liquid reservoir 200, and effectively avoiding the occurrence of core clogging.

[0063] In some embodiments, at least one capillary channel 132 is uniformly arranged along the circumference of the liquid inlet channel 130, so that the gas is discharged uniformly and the atomizing matrix can be uniformly and quickly guided from the second liquid storage chamber 211 to the first liquid storage chamber 111.

[0064] In some embodiments, the inner wall of the liquid inlet channel 130 is provided with a plurality of protrusions 133, which are spaced apart along the circumference of the liquid inlet channel 130 to form a capillary channel 132 between two adjacent protrusions 133. The protrusions 133 are integrally formed with the liquid inlet channel 130. Of course, the capillary channel 132 can also be formed by forming a groove on the inner wall of the liquid inlet channel 130. The surface of the protrusion 133 facing the center of the liquid inlet channel 130 is planar, and the cross-section of the protrusion 133 in the axial direction of the liquid inlet channel 130 is rectangular, trapezoidal, semi-circular, or triangular.

[0065] In some embodiments, the protrusion 133 is a strip-shaped structure extending axially along the liquid inlet channel 130. The liquid inlet channel 130 includes a first end and a second end. The first end is connected to the first liquid storage chamber 111, and the second end is connected to the second liquid storage chamber 211. The protrusion 133 is a strip-shaped structure that can guide the atomizing matrix to flow from the second end to the first end along the axial direction of the liquid inlet channel 130, and guide the gas to be discharged from the second end to the first end.

[0066] Please see Figure 8 In some embodiments, the capillary channel 132 has a depth D, a width W, and a length L. The depth D of the capillary channel 132 in the radial direction of the liquid inlet channel 130 is defined as the depth D, the width W of the capillary channel 132 in the circumferential direction of the liquid inlet channel 130 is defined as the width W, and the length L of the capillary channel 132 in the axial direction of the liquid inlet channel 130 is defined as the length L. The depth D of the capillary channel 132 in the radial direction of the liquid inlet channel 130 is 0.1 mm to 2 mm; and / or, the width W of the capillary channel 132 in the circumferential direction of the liquid inlet channel 130 is 0.1 mm to 2 mm; and / or, the length L of the capillary channel 132 in the axial direction of the liquid inlet channel 130 is 0.1 mm to 10 mm.

[0067] In some embodiments, the number of capillary channels 132 is 1-10. The number of capillary channels 132 and the size of the capillary channels 132 are also related, designed to ensure smooth liquid supply and convenient cutting. Optionally, the number of capillary channels 132 is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.

[0068] In some embodiments, the axis of the liquid inlet channel 130 is a straight line extending in the assembly direction of the liquid reservoir 200 and the atomizer 100, which reduces the resistance to liquid flow and gas discharge, and further effectively ensures stable and sufficient liquid supply.

[0069] This application also provides an atomizer 100, including a first housing 110 and an atomizing component 120. The atomizer 100 has been described in detail above and will not be repeated here.

[0070] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
