Description

Technical Field

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

[0002] Due to various factors such as cost and regulations, the amount of liquid matrix stored inside electronic atomizing devices is generally relatively small. When the liquid matrix is ​​depleted, it can be used again by refilling the liquid or replacing the atomizer, or it can be discarded directly. These methods, on the one hand, cause inconvenience to users and reduce their user experience, and on the other hand, increase their operating costs.

[0003] One solution is to use a larger-capacity liquid reservoir to replenish the liquid matrix to the main body of the electronic atomizer, thereby reducing user costs and improving the user experience. However, this solution has a problem: the liquid matrix in the reservoir cannot flow smoothly to the main body of the atomizer, resulting in issues such as cloying or a dry taste when vaping. Utility Model Content

[0004] This application aims to provide an electronic atomizing device to avoid problems such as burnt vaping or dry vaping sensation.

[0005] This application provides an electronic atomizing device, comprising:

[0006] A first housing, wherein a first liquid storage chamber for storing a liquid matrix is ​​formed within the first housing;

[0007] An atomizing core is disposed in the first housing and in fluid communication with the first liquid storage chamber. The atomizing core is used to atomize a liquid matrix to generate an aerosol.

[0008] A liquid storage medium is disposed in the first liquid storage chamber, and the liquid storage medium is used to hold the liquid matrix;

[0009] A connector is provided on the first housing;

[0010] The second housing has a second liquid storage chamber formed therein for storing the liquid matrix;

[0011] A liquid guiding column is disposed in the second housing. The open end of the liquid guiding column is in fluid communication with the second liquid storage chamber. The closed end of the liquid guiding column protrudes from the second housing. A liquid outlet hole is provided on the side wall of the liquid guiding column. A drainage groove extending from the liquid outlet hole to the closed end is also provided on the outer surface of the liquid guiding column.

[0012] The liquid guide column can be inserted into the insertion interface, thereby establishing a connection channel between the first liquid storage chamber and the second liquid storage chamber; when the liquid guide column is inserted into the insertion interface, the liquid guide column remains in contact with the liquid storage medium.

[0013] In the above electronic atomizing device, the liquid guide column is kept in contact with the liquid storage medium. Through the drainage groove on the outer surface of the liquid guide column, the liquid matrix in the second liquid storage chamber can be smoothly guided to the first liquid storage chamber, avoiding problems such as smearing or dry taste when vaping, thus improving the user's vaping experience.

[0030] As used here, the terms “up,” “down,” “left,” “right,” “inner,” “outer,” and similar expressions are used for illustrative purposes only.

[0031] As used herein, the terms “first,” “second,” etc., are used to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, particular order, or primary or secondary relationship of the indicated technical features.

[0032] like Figures 1-4 As shown, an embodiment of this application provides an electronic atomizing device including a device body 100 and a liquid storage component 200.

[0033] The main body 100 of the device includes a first housing 101, which may be composed of multiple components, such as a main housing 101a and a secondary housing 101b at least partially covering the top of the main housing 101a; the first housing 101 may also be integrally formed. The first housing 101 has a receiving cavity 101c, which communicates with the outside of the first housing 101 through an opening 101d provided at the top of the first housing 101. The liquid storage component 200 is at least partially removably received in the receiving cavity 101c through the opening 101d.

[0034] A first reservoir 102 for storing a liquid matrix is ​​formed within the first housing 101. The liquid matrix may be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavor components. Flavorings may include ingredients capable of providing the user with a variety of fragrances or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. In addition, the liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0035] The first liquid storage chamber 102 contains a liquid storage medium 103, which is made of, for example, a fibrous material or a porous material. Figure 5 As shown, the liquid storage medium 103 is generally tubular in shape, with a through hole 103a at its center and a venting groove 103b on its outer surface. The liquid storage medium 103 can adsorb and retain the liquid matrix. After injection, when the liquid storage medium 103 reaches saturation, the content of the liquid matrix in the liquid storage medium 103 is between 0.1 ml and 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml, etc.

[0036] The receiving cavity 101c and the first liquid storage cavity 102 are arranged sequentially along the longitudinal direction of the first housing 101, and the receiving cavity 101c and the first liquid storage cavity 102 are arranged on one side of the width direction of the first housing 101, for example... Figure 4 As shown on the left side, the first liquid storage chamber 102 is located below the receiving chamber 101c. A sealing member 104 is also provided inside the first housing 101. The sealing member 104 is disposed between the receiving chamber 101c and the first liquid storage chamber 102, thereby separating the receiving chamber 101c from the first liquid storage chamber 102.

[0037] like Figures 6-7As shown, the sealing element 104 is sheet-shaped, and its edge abuts against the protrusion 101e on the inner surface of the first housing 101, thereby separating the receiving cavity 101c from the first liquid storage cavity 102. The sealing element 104 is provided with a through hole 104a and an insertion interface 104b, both of which penetrate the upper and lower end faces of the sealing element 104. There are two insertion interfaces 104b, located on either side of the through hole 104a. A venting groove 104a1 is provided on the inner surface of the through hole 104a. A gap 102a exists between the upper end face of the liquid storage medium 103 and the lower surface of the sealing element 104 facing the first liquid storage cavity 102. One end of the venting groove 104a1 communicates with this gap 102a, and the other end of the venting groove 104a1 communicates with the through hole 104a. The upper surface of the seal 104 facing the receiving cavity 101c is also provided with one or more liquid storage tanks 104c for storing leaked liquid matrix.

[0038] A sealing element 105 is also provided inside the first housing 101, and the sealing element 105 is disposed near the lower end face of the liquid storage medium 103. A gap 102b is also provided between the lower end face of the liquid storage medium 103 and the upper surface of the sealing element 105 facing the first liquid storage cavity 102. The gap 102a between the upper end face of the liquid storage medium 103 and the lower surface of the sealing element 104 facing the first liquid storage cavity 102 can communicate with the gap 102b between the lower end face of the liquid storage medium 103 and the upper surface of the sealing element 105 facing the first liquid storage cavity 102 through a vent groove 103b. A through hole 105a is provided on the sealing element 105.

[0039] The first housing 101 is provided with an atomizing core 106, which is used to atomize the liquid matrix to generate an aerosol.

[0040] like Figure 8 As shown, the atomizing core 106 includes a liquid guiding element 106a and a heating element 106b. The liquid guiding element 106a can absorb the liquid matrix in the liquid storage medium 103 and transfer the liquid matrix to the heating element 106b. The heating element 106b can be heated by an electric current supply and transfers heat to the liquid matrix in contact with the heating element 106b to heat the liquid matrix, thereby generating an aerosol.

[0041] The liquid-conducting element 106a is configured as a tubular structure. Alternatively, in other examples, the liquid-conducting element 106a is configured as a plate-like structure or other regular or irregular shapes. The liquid-conducting element 106a can be made of a flexible fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the liquid-conducting element 106a can also be a rigid porous body, such as porous ceramics or porous glass. In the example shown in the figure, the outer surface of the liquid-conducting element 106a has a radially outward protrusion 106a1.

[0042] The heating element 106b is disposed near the inner surface of the liquid guiding element 106a and can abut against the inner surface of the liquid guiding element 106a. Alternatively, in other examples, the heating element 106b is partially or completely embedded in the liquid guiding element 106a. The heating element 106b can be a resistance heating mesh, a resistance heating coil, etc. The heating element 106b can be made of a material with suitable temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In the example shown in the figure, the heating element 106b is wound from a sheet or mesh substrate, and the wound heating element 106b is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length of the device body 100. Conductive leads 106c and conductive leads 106d are welded or arranged at both ends of the heating element 106b for guiding current in the heating element 106b. In other examples, the heating element 106b can be configured as a structure wound around the liquid guiding element 106a.

[0043] A connecting pipe 107 is also provided inside the first housing 101. The connecting pipe 107 extends along the axial direction of the first liquid storage chamber 102. The connecting pipe 107 is disposed in the through hole 103a, and the liquid storage medium 103 is sleeved on the connecting pipe 107. The upper end of the connecting pipe 107 is inserted into the through hole 104a of the sealing member 104, and the lower end of the connecting pipe 107 is inserted into the through hole 105a of the sealing member 105. The connecting pipe 107 is preferably made of a relatively thin rigid material, such as glass fiber or stainless steel.

[0044] In a preferred embodiment, the inner diameter of the liquid storage medium 103 is slightly smaller than the outer diameter of the connecting pipe 107, so that the liquid storage medium 103 is tightly fitted onto the connecting pipe 107. The atomizing core 106 is disposed inside the connecting pipe 107. The atomizing core 106 is coaxially disposed with the connecting pipe 107. The side wall of the connecting pipe 107 also has a liquid guide port 107a disposed near the lower end of the connecting pipe 107. The liquid storage medium 103 covers the liquid guide port 107a, and part of the liquid guiding element 106a is exposed in the first liquid storage chamber 102 through the liquid guide port 107a, so that this part of the liquid guiding element 106a is disposed close to the liquid storage medium 103 and keeps in contact with the liquid storage medium 103, thereby allowing the liquid matrix in the first liquid storage chamber 102 to flow into the atomizing core 106 through the liquid guide port 107a, that is, to be absorbed by the liquid guiding element 106a and atomized by the heating element 106b to generate an inhalable aerosol.

[0045] A notch 107b is also provided on the side wall of the connecting pipe 107, extending from the upper end of the connecting pipe 107 toward the lower end. The protruding portion 106a1 of the liquid guiding element 106a extends into the notch 107b, thereby exposing it in the first liquid storage chamber 102. After assembly, the liquid storage medium 103 remains in contact with a portion of the protruding portion 106a1, thereby facilitating the liquid guiding element 106a to absorb the liquid matrix.

[0046] An air inlet 101f is provided at the bottom of the first housing 101. (Reference) Figure 4 As shown in the airflow channel S1, external air flows into the first housing 101 through the air inlet 101f, then flows into the connecting pipe 107 after passing through the through hole 105a of the seal 105. After mixing with the aerosol generated by the atomizing core 106, it flows out from the through hole 104a of the seal 104. The ventilation groove 104a1 is connected to the airflow channel S1. Through the ventilation groove 104a1 and the ventilation groove 103b, the air pressure between the first liquid storage chamber 102 and the outside can be better balanced, ensuring that the liquid matrix can be smoothly guided to the atomizing core 106.

[0047] The first housing 101 also contains a circuit 108, which controls the overall operation of the electronic atomizing device. Specifically, the circuit 108 controls not only the operation of the battery 109 and the atomizing coil 106, but also the operation of other components in the electronic atomizing device. Furthermore, the circuit 108 can determine whether the electronic atomizing device is operational by checking the status of its components.

[0048] Circuit 108 includes at least one control unit. The control unit may include a logic gate array, or may include a combination of a general-purpose microcontroller and memory for storing programs executable in the microcontroller. Furthermore, those skilled in the art will understand that circuit 108 may include another type of hardware.

[0049] The battery cell 109 provides power for operating the electronic atomizing device. For example, the battery cell 109 can provide power to heat the atomizing coil 106 and can provide the power required to operate the circuitry 108. Furthermore, the battery cell 109 can provide power required to operate other components provided in the electronic atomizing device. The battery cell 109 can be a rechargeable battery or a disposable battery. The battery cell 109 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery cell 109 can be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. In the example shown in the figure, the battery cell 109 is arranged on the opposite side of the width direction of the first housing 101, as shown on the right side of the figure.

[0050] It should be noted that only components relevant to this embodiment are shown in the figures. Those skilled in the art will understand that the device body 100 may also include, in addition to... Figures 1-6 Other common components besides those shown. For example, a suction detector 110 may also be provided inside the first housing 101 to detect the user's suction action and generate a corresponding electrical signal, i.e., to detect whether the electronic atomizing device is being suctioned, so that the circuit 108, such as the control unit, controls the operation of the battery 109, atomizing core 106, etc., according to the electrical signal. For example, it controls the battery 109 to provide power to the atomizing core 106 so that the atomizing core 106 heats and atomizes the liquid matrix. The suction detector 110 can be a common pressure sensor, differential pressure sensor, airflow sensor, etc. The upper surface of the suction detector 110 is connected to the airflow channel S1, and the lower surface of the suction detector 110 is connected to the outside through the through hole 101g on the bottom wall of the first housing 101, so that changes in the suction airflow can be sensed when the user is suctioning.

[0051] The liquid storage component 200 includes a second housing 201. The second housing 201 may be composed of multiple components, such as a main housing 201a and a bottom cover 201b. The main housing 201a is connected to the bottom cover 201b. In a preferred embodiment, a portion of the bottom cover 201b extends into the main housing 201a, and the main housing 201a and the bottom cover 201b are detachably connected, for example, by a snap-fit ​​connection.

[0052] A second liquid storage chamber 202 for storing a liquid matrix is ​​formed within the second housing 201. In a preferred embodiment, a sealing element 203 is also provided within the second housing 201, with at least a portion of the sealing element 203 sandwiched between the bottom cover 201b and the main housing 201a, to reduce the risk of leakage of the liquid matrix from the gap between the bottom cover 201b and the main housing 201a.

[0053] Similarly, the liquid matrix stored in the second reservoir 202 can be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavorings. Flavorings may include ingredients capable of providing the user with a variety of aromas or flavors. Vitamin mixtures may be substances containing at least one of vitamins A, B, C, and E, but are not limited to. Additionally, the liquid matrix stored in the second reservoir 202 may include aerosol forming agents such as glycerin and propylene glycol.

[0054] It should be noted that the liquid matrix stored in the second reservoir 202 may have different or the same composition or properties as the liquid matrix stored in the first reservoir 102. For example, in some examples, the liquid matrix stored in the second reservoir 202 may have a different composition or concentration than the liquid matrix stored in the first reservoir 102. In other examples, the liquid matrix stored in the second reservoir 202 may have the same composition as the liquid matrix stored in the first reservoir 102. In still other examples, the liquid matrix stored in the second reservoir 202 may be part of a liquid formulation, while the liquid matrix stored in the first reservoir 102 may be another part of the same liquid formulation. In yet another example, the liquid matrix stored in the second reservoir 202 may be introduced into the first reservoir 102 as a supplementary source to the liquid matrix stored in the first reservoir 102, thereby increasing the number of puffs in the electronic atomizing device.

[0055] Generally, the volume of the liquid matrix stored in the second liquid storage chamber 202 is between 0.1 ml and 10 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, 2 ml, 4 ml, 5 ml, 6 ml, 8 ml, 10 ml, etc. In a preferred embodiment, the volume of the second liquid storage chamber 202 is larger than the volume of the first liquid storage chamber 102. Typically, no liquid storage medium is placed in the second liquid storage chamber 202.

[0056] The second housing 201 is also provided with liquid guiding columns 201b1. The number of liquid guiding columns 201b1 is the same as the number of insertion ports 104b. In the example in the figure, there are two liquid guiding columns 201b1 and two insertion ports 104b. It is understandable that it is also feasible for the number of liquid guiding columns 201b1 and the number of insertion ports 104b to be one or more.

[0057] In the example shown in the figure, a liquid guiding column 201b1 is formed on the bottom cover 201b. One end of the liquid guiding column 201b1 is an open end 201b11, which is close to and in fluid communication with the second liquid storage chamber 202. The other end of the liquid guiding column 201b1 is a closed end 201b12, which protrudes from the bottom wall of the second housing 201. A liquid outlet hole 201b13 is provided on the side wall of the liquid guiding column 201b1, which is located close to the closed end 201b12. The outer surface of the liquid guiding column 201b1 is also provided with a drainage groove 201b14, which extends from the liquid outlet 201b13 to the closed end 201b12. The drainage groove 201b14 may be located only on the side wall of the liquid guiding column 201b1, or it may be located on both the side wall of the liquid guiding column 201b1 and the end face of the closed end 201b12. The number of liquid outlets 201b13 and drainage grooves 201b14 is not limited here.

[0058] The top of the second housing 201 is provided with a suction nozzle 201c; a transmission pipe 201a1 is provided inside the second housing 201, preferably integrally formed with the main housing 201a; a through hole 201b2 is provided on the bottom cover 201b. One end of the transmission pipe 201a1 is in fluid communication with the suction nozzle 201c, and the other end of the transmission pipe 201a1 is inserted into the through hole 201b2 and is in fluid communication with the outside of the second housing 201. Figure 4 As shown in the airflow channel S2, external air can flow into the transfer tube 201a1 from the other end of the transfer tube 201a1, and then flow out from the suction nozzle 201c after passing through the transfer tube 201a1, for example, being inhaled by the user. It is understood that at least part of the seal 203 is sandwiched between the bottom cover 201b and the transfer tube 201a1 to reduce the risk of leakage of the liquid matrix from the gap between the bottom cover 201b and the transfer tube 201a1; in a preferred embodiment, the seal 203 has through holes corresponding to the liquid guide column 201b1 and the transfer tube 201a1.

[0059] The liquid storage component 200 is independent of the device body 100. For example, when the product is in a packaged or unused state, the liquid storage component 200 is separate from the device body 100. Before use, the user can assemble the liquid storage component 200 onto the device body 100.

[0060] In one example, the liquid storage component 200 is detachably connected to the device body 100, that is, the second housing 201 is detachably connected to the first housing 101. In a preferred embodiment, the second housing 201 is provided with a snap-fit ​​buckle 201a2, and the inner surface of the receiving cavity 101c is provided with a snap-fit ​​hole 101h. The snap-fit ​​connection between the second housing 201 and the first housing 101 can be achieved through the snap-fit ​​buckle 201a2 and the snap-fit ​​hole 101h.

[0061] In one example, a guide post 101i is provided on the inner surface of the receiving cavity 101c, and a guide groove 201a3 is provided on the second housing 201. The guide post 101i and the guide groove 201a3 facilitate the assembly of the second housing 201 to the first housing 101.

[0062] refer to Figures 11-12 As shown, when the second housing 201 is connected to the first housing 101, a connecting channel can be established between the first liquid storage chamber 102 and the second liquid storage chamber 202. Specifically, the liquid guide column 201b1 can be inserted into the insertion interface 104b to establish the connecting channel. In this way, the liquid matrix stored in the first liquid storage chamber 102 can flow in from the opening end 201b11 of the liquid guide column 201b1, and after passing through the liquid guide column 201b1, flow out from the outlet hole 201b13 to the second liquid storage chamber 202.

[0063] When the liquid guide column 201b1 is inserted into the insertion interface 104b, the liquid guide column 201b1 and the liquid storage medium 103 are kept in contact. For example, the end face of the closed end 201b12 of the liquid guide column 201b1 is in contact with the upper end face of the liquid storage medium 103. In this way, the liquid matrix flowing out from the liquid outlet 201b13 can be guided to the liquid storage medium 103 through the drainage groove 201b14 (as shown in S3 in the figure). In this way, it can be ensured that the liquid matrix stored in the first liquid storage chamber 102 flows smoothly to the liquid storage medium 103, avoiding problems such as stickiness or dry taste when sucked.

[0064] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
