DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0034] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "left", and "right" in the directional descriptions refer to the left and right directions shown in the specific corresponding schematic diagrams, which may or may not be the left and right directions in normal use; "outside" and "inside" are both directions in normal use.

[0035] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0036] The utility model provides three types of atomizers. These three types of atomizers 1A, 1B, and 1C can all be used in the fields of medical treatment, beauty, and electronic cigarettes, and can store aerosol atomization substrates (including liquid medicines, plant leaf liquids), and can atomize the aerosol atomization substrates into aerosols that can be inhaled by people by heating.

[0037] The structure of the first atomizer 1A is described below, and in the process of description, the structures of the second atomizer 1B, the third atomizer 1C and other atomizers are combined to expand and illustrate the embodiments.

[0038] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the atomizer 1A includes a housing 11 (refer to Figure 1 ), elastic top cover 12, base 13 and heating assembly 14. The housing 11 has a liquid storage chamber 100 and an air outlet channel 200. The liquid storage chamber 100 is used to contain the aerosol atomization matrix, and the air outlet channel 200 is used to guide the aerosol in the atomizer 1A for the user to inhale. The elastic top cover 12 is elastic. Exemplarily, the material of the elastic top cover 12 is silicone. The elastic top cover 12 is arranged at one end of the liquid storage chamber 100, and the elastic top cover 12 is provided with a liquid inlet hole 120 for introducing the aerosol atomization matrix (refer to Figure 5 and Figure 6 ). Specifically, when the atomizer 1A is normally used by the user, the direction of the atomizer 1A is similar to Figure 1 , Figure 2 and Figure 3 In the orientation shown, the liquid storage chamber 100 is located above the elastic top cover 12, and the liquid inlet hole 120 is located below the liquid storage chamber 100, so that the aerosol atomized matrix in the liquid storage chamber 100 can automatically flow into the liquid inlet hole 120 under the action of gravity.

[0039] like Figure 2 As shown, the base 13 is arranged on a side of the elastic top cover 12 away from the liquid storage chamber 100, and the base 13 and the elastic top cover 12 form an atomizing chamber 300 connected to the liquid inlet hole 120. The atomizing chamber 300 has an air inlet 301 and an air outlet 302, the air inlet 301 is used to introduce the outside air into the atomizing chamber 300, and the air outlet 302 is used to guide the aerosol in the atomizing chamber 300 out of the atomizing chamber 300. Specifically, the air inlet 301 is connected to the outside air, and the air outlet 302 is connected to the air outlet channel 200. In the process of the user sucking the air outlet channel 200, the outside air flows through the air outlet 302, the atomizing chamber 300, the air outlet 302 and the air outlet channel 200 in sequence, and finally enters the user's oral cavity; the aerosol in the atomizing chamber 300 enters the user's oral cavity along with the air flow.

[0040] like Figure 2 and Figure 3 As shown, one end of the heating component 14 extends into the interior of the atomizing chamber 300 and is located below the liquid inlet hole, and the other end is used to connect the power supply component 2, which supplies power to the heating component 14. Among them, the way in which the heating component 14 is located below the liquid inlet hole 120 includes at least the following two types, the first is that the heating component 14 extends into the liquid inlet hole 120, and the second is that the heating component 14 abuts against the inner wall of the elastic top cover 12 without extending into the liquid inlet hole 120. The aerosol atomization matrix in the liquid storage chamber 100 enters the heating component 14 under the action of gravity (the heating component 14 can have a large number of micropores to absorb the aerosol atomization matrix. Exemplarily, the heating component 14 is a matrix made of porous glass, porous ceramics, honeycomb ceramics, etc.). Under the heating action of the heating component 14, the aerosol atomization matrix entering the heating component 14 is heated and evaporated and converted into an aerosol, and enters the atomizing chamber 300.

[0041] Among them, the shell 11, the base 13 and the heating component 14 are respectively in contact with the elastic top cover 12 to seal each other; contact can be understood as mutual extrusion or mutual abutment, and sealing can be understood as the two objects are connected together without a gap between the mutually abutting parts. It can be understood that the hardness of the shell 11, the base 13 and the heating component 14 is higher than the hardness of the elastic top cover 12. Then, after the shell 11, the base 13 and the heating component 14 are respectively in contact with the elastic top cover 12, the surface of the elastic top cover 12 is deformed, so that the gaps between the inner wall of the shell 11 and the surface of the elastic top cover 12, between the surface of the base 13 and the surface of the elastic top cover 12, and between the surface of the heating component 14 and the surface of the elastic top cover 12 are filled, thereby achieving sealing.

[0042] like Figure 2 and Figure 3As shown, the sealing connection formed by the elastic top cover 12 abutting against the inner wall of the housing 11 eliminates the need to set a sealing member between the elastic top cover 12 and the housing 11, and prevents the aerosol atomization matrix in the liquid storage chamber 100 from passing through the abutment between the elastic top cover 12 and the housing 11, and cannot reach the outside of the housing 11 and / or the atomization chamber 300. The sealing connection formed by the elastic top cover 12 abutting against the base 13 eliminates the need to set a sealing member between the elastic top cover 12 and the base 13, and prevents the aerosol in the atomization chamber 300 and / or the aerosol atomization matrix liquefied by cooling the aerosol from passing through the outer wall of the base 13, and cannot leak out of the base 13. The sealed connection formed by the elastic top cover 12 and the heating assembly 14 abuts against each other, eliminating the need to set a seal between the elastic top cover 12 and the heating assembly 14, and making it impossible for the aerosol atomized matrix in the liquid storage chamber 100 to pass through the abutment between the elastic top cover 12 and the heating assembly 14 after reaching the liquid inlet hole 120, but can only enter the micropores of the heating assembly 14, so as to be heated by the heating assembly 14; that is, the aerosol atomized matrix in the liquid storage chamber 100 cannot enter the atomization chamber 300 in the form of liquid, but can only enter the atomization chamber 300 in the form of aerosol. Therefore, the setting of the elastic top cover 12 not only forms a sealing effect, but also eliminates the need to set multiple seals.

[0043] It should be noted that in the embodiment of the present utility model, the structure and abutment form of the elastic top cover 12 and the base 13 are not limited to Figures 2 to 4 The mutually nested manner shown can also have other structures and abutment forms. Example 1, reference Figure 7 The plate-shaped elastic top cover 12' and the base 13' with a U-shaped cross section are in contact with each other. When assembled, the top surface M1 of the elastic top cover 12' forms a liquid storage chamber 100 (refer to Figure 2 ), the bottom surface M2 of the elastic top cover 12' abuts against the base 13', and the outer peripheral wall M3 of the elastic top cover 12' abuts against the housing 11 (reference Figure 2 ), the outer peripheral wall M4 of the base 13 ′ also abuts against the housing 11 (reference Figure 2 ). Example 2, reference Figure 8 The cross section of the elastic top cover 12" with an inverted U shape and the plate-shaped base 13" are in contact with each other. When assembled, the top surface M5 of the elastic top cover 12" forms a liquid storage chamber 100 (refer to Figure 2 ), the inner wall M6 of the elastic top cover 12″ abuts against the outer peripheral wall M7 of the base 13″, and the outer peripheral wall M8 of the elastic top cover 12″ abuts against the shell 11 (reference Figure 2 ). Example 3, reference Fig. 9 The elastic top cover 12'' with an inverted U-shaped cross section and the base 13'' with a U-shaped cross section abut against each other. When assembled, the top surface M9 of the elastic top cover 12'' forms a liquid storage chamber 100 (refer to Figure 2), the edge of the elastic top cover 12″′ and the edge of the base 13″′ are relatively abutted, and the outer peripheral wall M10 of the elastic top cover 12″′ and the outer peripheral wall M11 of the base 13″′ are both abutted against the shell 11.

[0044] The atomizer provided by the embodiment of the utility model includes a shell, an elastic top cover, a base and a heating assembly; the interior of the shell has a liquid storage chamber for accommodating an aerosol atomization matrix and an air outlet channel for guiding out the aerosol; the elastic top cover is arranged at one end of the liquid storage chamber, and the elastic top cover is provided with a liquid inlet hole for introducing the aerosol atomization matrix; the base is arranged on the side of the elastic top cover away from the liquid storage chamber, the base is connected to the elastic top cover and forms an atomization chamber connected with the liquid inlet hole, the atomization chamber has an air inlet and an air outlet, and the air outlet is connected with the air outlet channel; the heating assembly is located in the atomization chamber; wherein the shell, the base and the heating assembly are respectively abutted with the elastic top cover to seal each other. The embodiment of the utility model not only forms a sealing effect by arranging an elastic top cover, and making the shell, the base and the heating assembly abut against the elastic top cover respectively, but also eliminates the setting of multiple seals, thereby reducing the number of parts of the atomizer, helping to reduce material costs and improve assembly efficiency.

[0045] In some embodiments, Figure 2 and Figure 3 As shown, the elastic top cover 12 includes a top 121 and a first side 122, the top 121 is arranged at one end of the liquid storage chamber 100 and abuts the shell 11, and the first side 122 is arranged at the edge of the top 121 and protrudes in the direction away from the liquid storage chamber 100. The base 13 includes a bottom 131 and a second side 132, and the second side 132 is arranged at the edge of the bottom 131 and protrudes in the direction of the liquid storage chamber 100. Among them, the first side 122 abuts between the shell 11 and the second side 132 to seal each other; the liquid inlet hole 120 passes through the top 121. In this way, the elastic top cover 12 and the base 13 are mutually set to form an atomization chamber 300. Since the hardness of the second side 132 and the shell 11 is higher than the hardness of the first side 122 sandwiched between the second side 132 and the shell 11, the first side 122 is deformed under the extrusion of the second side 132 and the shell 11, and an annular seal will be formed. In the embodiment of the utility model, the first side portion 122 is sandwiched between the second side portion 132 and the housing 11 , so that the atomizing chamber 300 is annularly sealed by the elastic top cover 12 , thereby reducing the risk of aerosol in the atomizing chamber 300 leaking to the outside of the first side portion 122 .

[0046] In some embodiments, Figure 2 As shown, the air inlet 301 passes through the bottom 131, and the air outlet 302 passes through the second side portion 132 and the first side portion 122 in sequence (refer to Figure 3), the air outlet channel 200 is arranged outside the liquid storage chamber 100. Since the air outlet channel 200 is located outside the liquid storage chamber 100, the sealing requirement between the air outlet channel 200 and the liquid storage chamber 100 is eliminated, which helps to reduce the risk of leakage of the aerosol atomized matrix in the liquid storage chamber 100, and reduces the risk of leakage of the aerosol in the air outlet channel 200 to other parts inside the nebulizer 1.

[0047] The extending direction of the air outlet channel 200 is not limited in the embodiment of the present utility model. For example, Figure 2 As shown, parallel to the first direction a, a first atomizer 1A is formed; Fig.10 The second type of atomizer 1B is formed perpendicular to the first direction a. The advantages and disadvantages of these two types of atomizers are described in detail as follows:

[0048] like Figure 2 The first type of atomizer 1A shown is more in line with human behavior habits, specifically because: the overall extension direction of the atomizer 1A (the length direction of the atomizer), the extension direction of the air outlet channel 200 and the liquid storage chamber 100 are all parallel to the first direction a. According to human behavior habits, users usually hold the atomizer 1A in the extension direction of the atomizer 1A, so that the opening 201 of the air outlet channel 200 faces upward, so as to facilitate the suction action; and during the suction process, the liquid storage chamber 100 is always above the liquid inlet hole 120, so that the aerosol atomized matrix (liquid) in the liquid storage chamber 100 flows into the liquid inlet hole 120 under the action of gravity. Therefore, the embodiment of the utility model can facilitate the user's suction by setting the extension direction of the air outlet channel 200.

[0049] like Fig.10 The second type of atomizer 1B shown in the figure has fewer turns in the internal airflow and a smooth airflow. The specific reason is that the extension direction of the air outlet channel 200 is perpendicular to the extension direction of the liquid storage chamber 100. In this way, the airflow enters the atomizing chamber 300 from the air inlet 301 and then flows out from the air outlet 302. The airflow of the second type of atomizer 1B is compared with Figure 2 The airflow of the first type of atomizer 1A shown has fewer turns and flows more smoothly, so it is easier to carry the aerosol in the atomization chamber 300 into the user's oral cavity, thereby helping to improve the user's experience.

[0050] In some embodiments, forming Fig.11 The third type of atomizer 1C is shown. The air inlet 301 of the third type of atomizer 1C passes through the bottom 131, the air outlet 302 passes through the top 121, and the air outlet channel 200 is arranged outside the liquid storage chamber 100. The air outlet channel 200 passes through the top 121 of the elastic top cover 12 to guide the aerosol in the atomization chamber 300 into the user's oral cavity.

[0051] In some embodiments, the fourth atomizer is not shown in the figure, but for ease of understanding, reference can be made to Fig.11 The air inlet 301 of the fourth type of atomizer passes through the bottom 131, the air outlet 302 passes through the top 121, and the air outlet channel 200 passes through the liquid storage chamber 100. The air outlet channel 200 passes through the top 121 of the elastic top cover 12 to guide the aerosol in the atomization chamber 300 into the user's mouth.

[0052] The common features of the structures of the above-mentioned various atomizers are described below.

[0053] In some embodiments, Figure 2 , Fig.10 and Fig.11 As shown, the air inlet 301 and the air outlet 302 are far apart in the radial direction of the atomizing chamber 300, that is, the air inlet 301 and the air outlet 302 are respectively close to the two end points of the diameter of the atomizing chamber 300. The radial direction of the atomizing chamber 300 is perpendicular to the first direction a. Since the cross section perpendicular to the first direction a can be circular or non-circular; accordingly, the diameter of the atomizing chamber 300 can be understood as a straight line passing through the center of the atomizing chamber 300. In this way, the airflow passes through the atomizing chamber 300 along a long path, thereby taking away more aerosol in the atomizing chamber 300.

[0054] In some embodiments, Figure 2 and Figure 3 As shown, an extension column 1311 extending toward the top 121 is provided on the inner side of the bottom 131, and the air inlet 301 passes through the extension column 1311. Since the inner side of the bottom 131 forms the wall of the atomizing chamber 300, the aerosol in the atomizing chamber 300 will form a liquid after condensation. In the embodiment of the utility model, the extension column 1311 is provided, and the extension column 1311 is along the vertical direction a in the normal use state, so that the liquid in the atomizing chamber 300 accumulates to a certain amount, until it exceeds the height of the extension column 1311, and then it will flow out over the extension column 1311.

[0055] In some embodiments, Figure 5 and Figure 6 As shown, the liquid inlet hole 120 includes a first sub-hole 1201 and a second sub-hole 1202 that are sequentially connected along a first direction, and the first sub-hole 1201 and the second sub-hole 1202 are connected by a first step surface 1203. The heating component 14 (refer to Figure 2 and Figure 3 ) extends into the second sub-hole 1202 along the first direction and abuts against the first step surface 1203. The number, shape and size of the first sub-hole 1201 and the second sub-hole 1202 are not limited; specifically, one first sub-hole 1201 can be connected to one second sub-hole 1202, or multiple first sub-holes 1201 can be connected to the second sub-holes 1202 respectively. For example, refer to Figure 5 Two first sub-holes 1201 are provided, and one second sub-hole 1202 is provided, and the two first sub-holes 1201 are connected to the second sub-hole 1202 respectively.

[0056] Among them, reference Figure 3 The heating assembly 14 includes a heating element 141 and an ejector pin 142. The heating element 141 extends into the second sub-hole 1202 and fills the second sub-hole 1202. A heating wire (not shown) is provided inside the heating element 141 or on the surface facing the atomization chamber 300, and these heating wires are electrically connected to the ejector pin 142 to generate heat. The material of the substrate of the heating element 141 can be ceramic or a cotton core, but no matter what material the heating element 141 is made of, a large number of micropores are formed inside the substrate of the heating element 141.

[0057] The embodiment of the utility model extends the heating element 141 into the second sub-hole 1202 and fills the second sub-hole 1202 to abut against the elastic top cover 12, which is beneficial to reducing the flow path of the aerosol atomization matrix and reducing the loss of the aerosol atomization matrix. The aerosol generated after heating directly enters the atomization chamber 300 and is carried to the air outlet 302 by the gas entering the atomization chamber 300, which is beneficial to full utilization of the aerosol.

[0058] In some embodiments, Figure 5 and Figure 6 As shown, the inner wall of the second sub-hole 1202 is provided with a first annular protrusion 1204, and the first annular protrusion 1204 is arranged circumferentially along the inner wall of the second sub-hole 1202. Compared with the main body of the elastic top cover 12, the first annular protrusion 1204 can be compressed more densely, thereby increasing the tightness of the sealing connection between the elastic top cover 12 and the heating element 141, referring to Figure 3 , which improves the sealing effect between the elastic top cover 12 and the heating element 141.

[0059] In some embodiments, Figure 5 and Figure 6 As shown, the inner wall of the second sub-hole 1202 is provided with a connecting groove 1205, one end of the connecting groove 1205 is connected to the atomizing chamber 300, and the other end is connected to the first sub-hole 1201. Specifically, the connecting groove 1205 can penetrate the first annular protrusion 1204, so that the first annular protrusion 1204 forms a small notch 1206 as shown in the figure; or it can not penetrate the first annular protrusion 1204, so that the first annular protrusion 1204 and the inner wall of the second sub-hole 1202 form a small hole.

[0060] like Figure 2 and Figure 5As shown, since the aerosol atomized matrix in the liquid storage chamber 100 flows out under the action of gravity, if the interior of the liquid storage chamber 100 is a closed environment, as the aerosol atomized matrix continues to flow out, the air pressure in the liquid storage chamber 100 becomes smaller and smaller, and becomes smaller to a certain extent, so that the gravity of the aerosol atomized matrix cannot overcome the atmospheric pressure and cannot flow out. Therefore, the connection groove 1205 is provided to balance the atmospheric pressure inside and outside the liquid storage chamber 100, so that the aerosol atomized matrix can flow out normally.

[0061] In some embodiments, Figure 3 As shown, a first connection structure 123 is disposed on the outer side of the first side portion 122 , and a second connection structure 133 is disposed on the outer side of the second side portion 132 . The first connection structure 123 and the second connection structure 133 are connected to each other.

[0062] Exemplarily, the first connection structure 123 is formed with a card slot 1231, and the second connection structure 133 is formed with a card connection portion 1331. In this way, the connection between the elastic top cover 12 and the base 13 is more firmly established, and the sealing effect between the elastic top cover 12 and the base 13 is improved. In one embodiment, the card connection direction between the card connection portion 1331 and the card connection slot 1231 is the same as the sleeve connection direction between the first side portion 122 and the second side portion 132. When the first side portion 122 and the second side portion 132 are sleeved with each other during assembly, the card connection between the card connection portion 1331 and the card slot 1231 is completed at the same time, that is, the convenience of assembly is improved.

[0063] In one embodiment, if Figure 2 and Figure 3 As shown, the first connection structure 123 and the second connection structure 133 both extend into the air outlet channel 200, the first connection structure 123 covers the second connection structure 133, and the first connection structure 123 abuts against the housing 11. In this way, the top of the second connection structure 133 is sealed by the first connection structure 123, so that the aerosol at the air outlet 302 cannot pass through the abutment between the first connection structure 123 and the housing 11, thereby reducing the risk of aerosol leakage from the periphery of the air outlet 302.

[0064] In some embodiments, Figure 3 As shown, a second step surface 111 is provided in the housing 11, and the elastic top cover 12 abuts against the second step surface 111. On the one hand, the second step surface 111 plays a positioning role for the elastic top cover 12; on the other hand, it extends the leakage path of the aerosol generating matrix in the liquid storage chamber 100, that is, reduces the leakage risk.

[0065] In some embodiments, Figure 6As shown, the outer wall of the elastic top cover 12 is provided with a second annular protrusion 1207, and the second annular protrusion 1207 abuts against the inner wall of the housing 11. Compared with the main body of the elastic top cover 12, the second annular protrusion 1207 can be compressed more densely, thereby increasing the tightness of the sealing connection between the elastic top cover 12 and the housing 11, referring to Figure 2 , which improves the sealing effect between the elastic top cover 12 and the shell 11.

[0066] The present utility model also provides three electronic atomization devices. The first electronic atomization device is as follows: Fig.12 Shown, including Figures 1 to 9 The atomizer 1A shown in any of the figures, and the power supply assembly 2, the power supply assembly 2 is electrically connected to the atomizer 1A, and is used to supply power to the atomizer 1A.

Fig.14 Shown, including Fig.11 The atomizer 1C shown, and the power supply assembly 2, the power supply assembly 2 is electrically connected to the atomizer 1C for supplying power to the atomizer 1C.

[0067] Specifically, the power supply assembly 2 includes a battery 21, a microphone 22, a circuit board 23, etc.; the battery 21 is electrically connected to the heating assembly 14 to supply power to the heating assembly 14; the microphone 22 and the circuit board 23 are used to sense the internal airflow of the atomizer 1A / 1B / 1C to realize automatic opening and closing of the atomizer 1A / 1B / 1C.
