[0047] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] As Figures 1 to 4 shown, the embodiment of the present application provides an atomizing bracket, and the provided atomizing bracket can be used for an atomizer. As Figures 5 to 8 shown, the atomizer includes an oil cup 200, the oil cup 200 has an inner cavity, and the atomizing bracket 100 includes a bracket body 110 and a ventilation structure 120.

[0049] Among them: The outer wall of the bracket body 110 has a sealing connection area, and the sealing connection area is used for sealing contact with the inner wall of the inner cavity and for sealingly connecting the atomizing bracket 100 and the oil cup 200 to enclose a liquid storage cavity 210. The liquid storage cavity 210 is used for storing an atomizing medium (such as e-liquid or liquid medicine). The atomizing bracket 100 and the oil cup 200 are sealingly connected to prevent the atomizing medium in the liquid storage cavity 210 from leaking.

[0050] The ventilation structure 120 is arranged on the bracket body 110, and the ventilation structure 120 is used to cooperate with the inner wall of the inner cavity to form a ventilation channel connecting the liquid storage cavity 210 and the external atmosphere. When the atomizing bracket 100 is used for an atomizer, the ventilation channel can balance the air pressure in the liquid storage cavity 210 of the oil cup 200 and ensure the normal operation of the atomizer.

[0051] Optionally, the number of the ventilation structures 120 can be one or more.

[0052] In the embodiment of the present application, the bracket body 110 has a sealed connection area with sealing performance. The air exchange structure 120 is used to cooperate with the oil cup 200 to form an air exchange channel. Therefore, when the atomization bracket 100 in the embodiment of the present application is applied to an atomizer, after the atomization bracket 100 is assembled to the oil cup 200, the sealed connection area of the bracket body 110 can be in sealed contact with the inner wall of the inner cavity, enclosing a sealed liquid storage cavity 210. The air exchange structure 120 can cooperate with the inner wall of the inner cavity to form an air exchange channel, eliminating the need for additional sealing silica gel, reducing the material cost and assembly cost of the atomizer. Thus, it can be seen that the embodiment of the present application can solve the problem of high cost of atomizers in the prior art.

[0053] In addition, in the prior art, the atomization bracket 100 and the oil cup 200 are sealed and connected by sealing silica gel. Then, there may be gaps between the atomization bracket 100 and the sealing silica gel, and between the sealing silica gel and the oil cup 200. The existence of the gaps may cause the atomization medium in the liquid storage cavity 210 to have a risk of leakage. When the atomization bracket 100 in the embodiment of the present application is used in an atomizer, there is no need to use sealing silica gel between the atomization bracket 100 and the oil cup 200. While reducing the number of components, it also reduces the generation of gaps between the atomization bracket 100 and the oil cup 200, which is more conducive to the sealing of the atomizer and improves the sealing reliability of the atomizer.

[0054] The air exchange structure 120 may include a buffer groove 121, an air exchange port, and an air exchange hole 123. The flow-through area of the buffer groove 121 is larger than the flow-through areas of the air exchange port and the air exchange hole 123. The buffer groove 121 may be provided on the outer side wall of the bracket body 110. Both the air exchange port and the air exchange hole 123 communicate with the internal space of the buffer groove 121.

[0055] The edge of the buffer groove 121 that encloses the groove opening is used to contact the inner wall of the inner cavity and is used to cooperate with the inner wall of the inner cavity to enclose a buffer cavity. The air exchange port is used to communicate with the liquid storage cavity 210, that is to say, the air exchange port is used to communicate the liquid storage cavity 210 and the buffer cavity. The air exchange hole 123 is used to communicate with the external atmosphere, that is to say, the air exchange hole 123 is used to communicate the buffer cavity and the external atmosphere.

[0056] When the atomization bracket 100 is used in an atomizer, the external atmosphere can be sequentially communicated with the liquid storage cavity 210 through the air exchange hole 123, the buffer cavity, and the air exchange port, enabling the gas in the external atmosphere to enter the inside of the liquid storage cavity 210 through the air exchange hole 123, the buffer cavity, and the air exchange port, achieving the purpose of air exchange.

[0057] It should be noted that the flow-through area refers to the area through which the structure itself can allow air to pass, that is, the cross-sectional area of the cross-section perpendicular to the air flow direction inside the structure itself. For example, the flow-through area of the buffer groove 121 refers to the area through which the buffer groove 121 can allow air to pass, that is, the cross-sectional area of the cross-section perpendicular to the air flow direction inside the buffer groove 121.

[0058] Since the buffer groove 121 of the atomization bracket 100 can cooperate with the inner wall of the inner cavity to form a buffer cavity, when the atomizer performs the air exchange operation, the gas (such as air) in the buffer cavity forms a bubble. Since the buffer cavity is communicated with the external atmosphere through the air exchange hole 123, the air pressure of the bubble in the buffer cavity is equal to the external atmospheric pressure. For the bubble in the liquid storage cavity 210, as the atomization medium in the liquid storage cavity 210 is consumed, the bubble becomes larger and the pressure becomes smaller, forming a negative pressure. At this time, the air pressure in the buffer cavity will push the atomization medium at the air exchange port or located in the buffer cavity back into the liquid storage cavity 210, making it difficult for the atomization medium to leak to the outside through the air exchange channel, so that the air exchange channel is not easy to leak the atomization medium.

[0059] In addition, when the atomization medium in the liquid storage cavity 210 seeps into the buffer cavity through the air exchange port, according to fluid mechanics, when the liquid passes through a small cross-section into a large cross-section, both the speed and the pressure will decrease. Therefore, the atomization medium seeping into the buffer cavity will not directly rush into the air exchange hole 123. At the same time, in cooperation with the pressure difference between the buffer cavity and the liquid storage cavity 210, the atomization medium is pushed back into the liquid storage cavity 210, further playing a role in preventing leakage.

[0060] There are various structures of the air exchange port. In an optional embodiment, the air exchange port can be a through hole provided on the groove wall of the buffer groove 121. One side port of the through hole is used to communicate with the liquid storage cavity 210, and the other side port of the through hole communicates with the internal space of the buffer groove 121.

[0061] In another preferred embodiment, a ventilation notch 122 can be provided on the edge of the buffer groove 121 surrounding the notch. The air exchange port can include the ventilation notch 122. The ventilation notch 122 can cooperate with the inner wall of the inner cavity to form a ventilation slit. The ventilation slit communicates the liquid storage cavity 210 and the buffer cavity. One side port of the air exchange hole 123 is formed in the buffer groove 121. Compared with processing the through hole structure, the processing difficulty of the ventilation notch 122 is lower, which is more convenient for processing the atomization bracket 100.

[0062] In the embodiment of the present application, the flow-through area of the ventilation gap 122 (which is equal to the flow-through area of the ventilation slit) is smaller than the flow-through area of the ventilation hole 123. In such a structure, when the atomization bracket 100 is used in an atomizer, relatively speaking, the gas in the external atmosphere can smoothly enter the buffer cavity through the ventilation hole 123, while the atomization medium in the liquid storage cavity 210 is difficult or even unable to enter the buffer cavity through the ventilation slit. Or, the atomization medium entering the buffer cavity is easily pushed back into the liquid storage cavity 210 by the bubbles in the buffer cavity, further preventing the leakage of the atomization medium through the ventilation channel.

[0063] The atomization bracket 100 in the embodiment of the present application can be processed by die forming (optionally, when the atomization bracket 100 in the embodiment of the present application is made of elastic plastic material, the atomization bracket 100 can be formed by a plastic mold). It is very difficult to form a hole with a cross-sectional area less than 0.1 mm on the atomization bracket 100 by die forming (because the hole is too small, the steel material corresponding to the part of the mold used for processing the hole is too thin and easily breaks), while for a hole with a cross-sectional area greater than 0.1 mm 2 , the atomization medium (such as e-liquid) can easily pass through. 2

[0064] In the above embodiment of the present application, the ventilation opening can be the ventilation gap 122. When the atomization bracket 100 is processed by die forming, a ventilation gap 122 with a flow-through area less than 0.1 mm 2 can be processed.

[0065] Therefore, in a further technical solution, the minimum flow-through area of the ventilation gap 122 can be 0.02 - 0.07 mm 2 , for example, 0.02 mm 2 , 0.04 mm 2 , 0.07 mm 2 .

[0066] If the flow-through area of the ventilation gap 122 is greater than this size range, it is easy to cause the leakage of the atomization medium through the ventilation channel. If the flow-through area of the ventilation gap 122 is less than this size range, it is difficult to achieve the production process precision of the mold or the cost is too high. The ventilation gap 122 within this size range makes the atomization medium not easy to pass through, can effectively prevent the leakage of the atomization medium through the ventilation channel, and the production process precision of the mold can meet this requirement.

[0067] Along the air guiding direction of the ventilation gap 122, that is, along the air flow direction in the ventilation gap 122, optionally, the flow-through area of the ventilation gap 122 can change, or the flow-through area of the ventilation gap 122 can be equal everywhere.

[0068] The minimum flow-through area of the air vent 123 can be 0.1 to 0.4 mm 2 , for example, 0.1 mm 2 , 0.19 mm 2 , 0.2 mm 2 , 0.25 mm 2 , 0.3 mm 2 , 0.4 mm 2 . Along the air guiding direction of the air vent 123, that is, along the air flow direction in the air vent 123, the air vent 123 can be a hole with a constant diameter or a hole with a variable diameter (such as a stepped hole or a tapered hole).

[0069] There are various ways to provide the buffer groove 121 on the outer sidewall of the bracket body 110. In an alternative embodiment, a part of the outer wall of the bracket body 110 can be recessed inward to form the buffer groove 121.

[0070] In another preferred embodiment, the outer sidewall of the bracket body 110 can be provided with a recessed area 170, and the recessed area 170 can extend to the first surface of the bracket body 110 that is used to be exposed in the liquid storage cavity 210, so that the atomization medium in the liquid storage cavity 210 can enter the recessed area 170. A surrounding bone 160 can be protruded in the recessed area 170, and the surrounding bone 160 can enclose the buffer groove 121. The surrounding bone 160 is used to cooperate with the cavity wall of the inner cavity to enclose a buffer cavity. The air vent (such as the air vent gap 122 in the above embodiment) can be opened on the surrounding bone 160, and one side port of the air vent 123 can be located in the area enclosed by the surrounding bone 160.

[0071] Setting the surrounding bone 160 in the recessed area 170 can avoid the problem that the surrounding bone 160 protrudes too much from the outer surface of other areas of the atomization bracket 100, resulting in the sealing connection area being unable to effectively seal with the cavity wall of the inner cavity.

[0072] In a further technical solution, the surrounding bone 160 can be provided with air guiding strips 130 extending in the direction towards the first surface. The number of the air guiding strips 130 can be multiple, for example, two. The multiple air guiding strips 130 can be distributed around the air vent, and the multiple air guiding strips 130 are used to cooperate with the cavity wall of the inner cavity to form an air guiding space that can guide the gas flowing out of the air vent out of the recessed area 170 and towards the liquid storage cavity 210.

[0073] In this case, the bubbles overflowing from the air vent can flow out of the recessed area 170 relatively quickly under the guiding action of the air guiding space, enter the liquid storage cavity 210, and pass through the atomization medium in the liquid storage cavity 210 to reach the area with gas in the liquid storage cavity 210, accelerating the speed of air replacement and improving the air replacement efficiency.

[0074] In some embodiments, the flow-through area of the buffer groove 121 gradually decreases from the middle towards the ventilation gap 122 and the ventilation hole 123, so that when relatively large bubbles are formed in the buffer cavity, they can be stuck between the ventilation gap and the ventilation hole 123 to prevent the bubbles from directly blocking the ventilation gap 122 and the ventilation hole 123, resulting in abnormal air return.

[0075] In some embodiments, a three-dimensional structure may also be provided in the buffer groove 121. The three-dimensional structure may be a convex point 125 arranged in an array formed on the inner surface of the buffer groove 121. When bubbles are formed in the buffer groove 121, an over-flow gap may be formed between the convex points 125 arranged in an array and the surface of the bubbles to ensure the air return effect. Specifically, the convex point 125 may be a spherical segment with a spherical surface, and the spherical crown surface of the spherical segment is the surface in contact with the bubbles.

[0076] In some specific embodiments, the surface of the buffer groove 121 is a curved surface, and the gap between the inner surface of the oil cup 200 and the inner surface of the buffer groove 121 is a capillary gap. In this way, by setting the inner surface of the buffer groove 121 as a curved surface, the adhesion of the liquid to the inner surface of the buffer groove 121 is increased, and the risk of the liquid flowing from the buffer groove 121 to the outside through the ventilation hole 123 is reduced, thereby reducing the risk of the atomization medium flowing from the buffer groove 121 to the outside through the ventilation hole 123. An atomizer is a device that can be used by users to inhale. Therefore, the atomizer further includes an air inlet channel and an air outlet channel 220. The bracket body 110 has an installation chamber 111. The port of the ventilation hole 123 away from the buffer groove 121 may be located on the inner wall of the inner chamber of the installation chamber 111 and communicate with the installation chamber 111. The installation chamber 111 is used to communicate with the air inlet channel, and the port of the ventilation hole 123 away from the buffer groove 121 is used to communicate with the outside atmosphere through the installation chamber 111 and the air inlet channel.

[0077] In this case, when the atomization bracket 100 is used in the atomizer, the ventilation hole 123 communicates with the air inlet channel through the installation chamber 111, and then communicates with the outside atmosphere through the air inlet channel, realizing the communication between the ventilation hole 123 and the outside atmosphere.

[0078] In the specific structure of the atomizer, the oil cup 200 has an opening communicating with the inner cavity. The air outlet channel 220 of the atomizer is arranged in the oil cup 200. The atomization bracket 100 may be provided with a communication hole 112, and the communication hole 112 communicates the air outlet channel 220 and the installation chamber 111. Except for the oil cup 200, the atomizer includes an atomization assembly including the atomization bracket 100, the base 300, and the atomization core.

[0079] Among them, at least part of the atomization component enters the inner cavity through the opening of the oil cup 200 and is connected to the inner cavity in a matching manner. It is hermetically connected to the oil cup 200 through the sealing connection area of the atomization bracket 100 to form a sealed liquid storage cavity 210. Part of the base 300 extends into the installation chamber 111, is connected to the installation chamber 111, and blocks the opening of the installation chamber 111. The part of the base 300 located outside the installation chamber 111 can be snap-connected to the oil cup 200 and block the opening of the oil cup 200. The air inlet channel is opened on the base 300. The atomization core can be installed in the installation chamber 111 of the atomization bracket 100 by means of snap connection or the like. The atomization core is used to atomize the atomization medium. The installation chamber 111 is communicated with the air outlet channel 220 of the oil cup 200. When using the atomizer, the gas in the external atmosphere enters the air inlet channel and flows in the direction of the air outlet channel 220. When passing through the atomization core, the gas is mixed with the atomized atomization medium to form an aerosol. The aerosol enters the air outlet channel 220 through the communication hole 112 and then flows out through the air outlet channel 220 for the user to inhale.

[0080] In the embodiment of the present application, the inner wall of the installation chamber 111 has an atomization core installation area for installing the atomization core. The port of the air exchange hole 123 far from the buffer groove 121 is located in the atomization core installation area, is used to contact the atomization core, and is used to communicate with the external atmosphere through the atomization core, the installation chamber 111, the air inlet channel in sequence.

[0081] When the atomization bracket 100 is used in the atomizer, the port of the air exchange hole 123 far from the buffer groove 121 contacts the atomization core. When the atomizer exchanges air, the gas in the external atmosphere sequentially passes through the air inlet channel, the atomization core, the air exchange hole 123, the buffer cavity, and the air exchange notch 122 to enter the liquid storage cavity 210 to complete the air exchange.

[0082] In this structure, even if the atomization medium in the liquid storage cavity 210 leaks through the air exchange notch 122, the buffer cavity, and the air exchange hole 123 in sequence, the leaked atomization medium will enter the atomization core, and the atomization medium entering the atomization core will participate in the aerosol generation process, thereby preventing the atomization medium from leaking outside the atomizer and further improving the anti-leakage performance of the atomization channel.

[0083] Specifically, the atomization core may include an oil guiding body and a heating body. The oil guiding body can be installed in the atomization core installation area of the installation chamber 111, and the atomization medium leaking through the air exchange channel enters the oil guiding body and participates in the aerosol generation process.

[0084] The atomization bracket 100 is also provided with a liquid passing port 140, which is opposite to a partial area of the atomization core installation area. The liquid passing port 140 penetrates through one side wall of the installation bin 111 and is used to connect the liquid storage cavity 210 and the atomization core, so that the atomization medium in the liquid storage cavity 210 enters the atomization core, enabling the atomization core to atomize the atomization medium. The air exchange structure 120 and the liquid passing port 140 can be located on the same side wall of the bracket body 110. In this positional relationship, the air exchange hole 123 and the liquid passing port 140 are adjacent in position, facilitating the processing of the air exchange hole 123, and thus facilitating the processing of the atomization bracket 100.

[0085] When the number of the air exchange structures 120 is multiple, the multiple air exchange structures 120 can be distributed on both sides of the liquid passing port 140. Of course, in other embodiments, the multiple air exchange structures 120 can also be distributed on the same side of the liquid passing port 140.

[0086] In the above embodiment, the buffer groove 121 is used to cooperate with the inner wall of the liquid storage cavity 210 to form a buffer cavity, and the buffer cavity can prevent the atomization medium in the liquid storage cavity 210 from leaking out through the air exchange channel.

[0087] In a further technical solution, at least one spacer 124 can be arranged in the buffer groove 121. The spacer 124 can be a spacer rib. All the spacers 124 divide the buffer groove 121 into multiple buffer areas. A communication gap 1241 is provided on the surface of each spacer 124 facing away from the bracket body 110. The communication gap 1241 communicates two adjacent buffer areas. The air exchange hole 123 is communicated with the air exchange port through each buffer area and each communication gap 1241. The minimum flow-through area of the communication gap 1241 can be 0.02 - 0.07 mm 2 。

[0088] The surface of the spacer 124 facing away from the bracket body 110 is used to contact the wall of the inner cavity and is used to divide the buffer cavity into multiple sub-buffer cavities communicated through the communication gap 1241.

[0089] When the atomization bracket 100 is used in an atomizer, the buffer cavity is divided into multiple sub-buffer cavities by the spacer. Adjacent sub-buffer cavities are communicated through the communication gap 1241. The air exchange hole 123 is communicated with the liquid storage cavity 210 through each sub-buffer cavity, each communication gap 1241 and the air exchange port.

[0090] In this case, the atomization medium in the liquid storage cavity 210 can be blocked by the air exchange gap 122 and can also be blocked by the communication gap 1241, further improving the anti-leakage effect of the air exchange channel formed by the cooperation of the air exchange structure 120 of the atomization bracket 100 and the liquid storage cavity 210.

[0091] Optionally, a plurality of spacers 124 may be arranged in sequence along the direction from the ventilation holes 123 to the ventilation ports, and the distances from each communication notch 1241 to the ventilation ports may gradually decrease, so as to make the ventilation process smoother.

[0092] In the above embodiment, a sealing connection area is provided on the outer side wall of the bracket body 110. In an alternative embodiment, at least one annular protrusion 150 may protrude from the outer side wall of the bracket body 110, and the annular protrusion 150 may form a sealing connection area. In the atomization bracket 100, at least the annular protrusion 150 is made of elastic plastic material.

[0093] In another alternative embodiment, the bracket body 110 may include a first part and a second part distributed in a stepped manner. After the atomization bracket 100 is assembled to the oil cup 200, the first part is closer to the opening of the oil cup 200, the outer side wall of the first part forms a sealing connection area, and the ventilation structure is arranged on the second part. The second part is closer to the air outlet channel 220 of the oil cup 200. In such an atomization bracket 100, at least the first part is made of elastic plastic material.

[0094] Certainly, in the embodiments of the present application, the entire atomization bracket 100 may be made of elastic plastic material. In this way, the atomization bracket 100 can not only use the soft characteristics of the elastic plastic for sealing, but also use the hard body characteristics of the elastic plastic as a hard support for the atomization component.

[0095] Optionally, the elastic plastic material of the atomization bracket 100 in the embodiments of the present application may be TPE (Thermoplastic Elastomer), TPEE (thermoplastic polyester elastomer, also known as polyester rubber, which is a linear block copolymer containing PBT (polybutylene terephthalate) polyester hard segments and aliphatic polyester or polyether soft segments), PVC (Polyvinyl chloride), TPU (thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, which is a (AB)n type block linear polymer, A is a polyester or polyether with a high molecular weight (1000 - 6000), B is a diol containing 2 - 12 straight-chain carbon atoms, and the chemical structure between the AB chain segments is a diisocyanate). Of course, the material of the atomization bracket 100 may also be other types of elastic plastic, and the present application does not limit this.

[0096] Please refer to Figures 5 to 8, based on the above atomization bracket, the embodiment of the present application further provides an atomizer, which can be used in an electronic cigarette. The atomizer includes an oil cup 200 and the above atomization bracket 100. The oil cup 200 has an inner cavity, and the atomization bracket 100 is located inside the inner cavity. The sealing connection area of the bracket body 110 is in sealing contact with the inner wall of the inner cavity, so that the atomization bracket 100 and the oil cup 200 enclose a liquid storage cavity 210. The air exchange structure 120 of the atomization bracket 100 cooperates with the inner wall of the inner cavity to form an air exchange channel, and the air exchange channel communicates the liquid storage cavity 210 with the external atmosphere. For the structure of the air exchange channel, please refer to the above content and will not be elaborated here.

[0097] Since the atomizer has the above atomization bracket, for the beneficial effects brought by the atomization bracket to the atomizer, please refer to the above content and will not be elaborated here.

[0098] As can be seen from the atomization bracket 100 in the above content, the air exchange structure 120 includes a buffer groove 121, an air exchange port, and an air exchange hole 123. The buffer groove 121 is located on the outer side wall of the bracket body 110. The notch of the buffer groove 121 is in contact with the inner wall of the inner cavity, so that the buffer groove 121 and the inner wall of the inner cavity cooperate to enclose a buffer cavity. The air exchange port communicates the liquid storage cavity 210 with the buffer cavity, and the air exchange hole 123 communicates the liquid storage cavity 210 with the external atmosphere. Along the air flow direction from the air exchange hole 123 to the air exchange port, the distance from the air exchange port to the liquid storage cavity 210 is less than the distance from the air exchange hole 123 to the liquid storage cavity 210, so as to prevent large-angle reversion of the air flow during the air exchange process, thereby ensuring the smoothness of the air exchange process.
