Description

Technical Field

[0001] This application relates to the field of atomizer technology, and in particular to an atomizer holder and an atomizer. Background Technology

[0002] An atomizer includes an oil cup, an atomizing bracket, and an atomizing coil. The atomizing coil is mounted on the atomizing bracket and is used to absorb the oil in the oil cup's reservoir into the atomizing coil and heat it for atomization. As the amount of oil in the reservoir is continuously consumed, negative pressure can easily form in the reservoir, reducing the oil extraction efficiency and causing problems such as dry burning of the atomizing coil and the production of a burnt smell, which affects the normal operation of the atomizer. Summary of the Invention

[0003] Therefore, it is necessary to provide an atomizing bracket and atomizer that can improve the oil output efficiency and enhance the stability of the atomizer's operation.

[0004] In a first aspect, embodiments of this application provide an atomizing bracket, comprising:

[0005] The bracket body is used to be installed inside the oil cup. The bracket body has a first groove, a second groove, and a vent hole. The first groove is used to communicate with the liquid storage chamber of the oil cup, and the second groove is used to install the atomizing core. The oil outlet penetrates the bottom wall of the second groove and communicates with the first groove. The vent hole is used to connect the liquid storage chamber with the external environment so that external air can enter the liquid storage chamber through the vent hole.

[0006] In one embodiment, in a first direction, one end of the bracket body is provided with a first through hole, one end of the first through hole in the first direction is connected to the second groove, and the other end of the first through hole in the first direction is used to connect to the air outlet channel of the oil cup, and the first direction is parallel to the axial direction of the bracket body.

[0007] In one embodiment, the support body has an air exchange channel, which is connected to the end of the second groove away from the first through hole in the first direction, and the air exchange channel is used to communicate with the outside air.

[0008] In one embodiment, on a projection plane perpendicular to the first direction, the projection of the air exchange channel is a curve or broken line structure with alternating concave and convex shapes.

[0009] In one embodiment, a reflux groove is provided on the support body, one end of the reflux groove is connected to the first through hole, and the other end of the reflux groove is connected to the second groove.

[0010] In one embodiment, the outer peripheral wall of the support body has a first annular sealing portion, and the side of the support body facing the opening of the first groove has a second annular sealing portion, with the first through hole located inside the second annular sealing portion; the oil cup includes a first annular wall and a second annular wall located inside the first annular wall;

[0011] Wherein, the outer wall of the first annular sealing part is used to abut and seal against the inner wall of the first annular wall, and the inner wall of the second annular sealing part is used to abut and seal against the outer wall of the second annular wall, so that the liquid storage cavity is formed inside the oil cup.

[0012] In one embodiment, the outer peripheral wall of the support body is provided with an oil inlet notch, which communicates with the first groove.

[0013] In one embodiment, the outer peripheral wall of the support body is provided with a plurality of condensation grooves for storing condensate.

[0014] In one embodiment, the number of oil outlets is plurality of, and the plurality of oil outlets are spaced apart in a second direction, the second direction being perpendicular to the axial direction of the support body; and / or,

[0015] The oil outlet is a strip-shaped hole, and the length direction of the oil outlet is parallel to the axial direction of the bracket body.

[0016] Secondly, embodiments of this application also provide an atomizer, including an atomizing core and an atomizing bracket as described in any one of the first aspects. The atomizing core includes an oil guide and a heating element. The oil guide is installed in the second groove and is used to guide the oil in the liquid storage chamber. The heating element is attached to the side of the oil guide facing away from the bottom wall of the second groove and is used to atomize the oil in the oil guide.

[0017] The aforementioned atomizing bracket includes a bracket body, which is installed inside an oil cup. The bracket body has a first groove, a second groove, an oil outlet, and a vent. The first groove communicates with the liquid storage chamber of the oil cup, and the second groove is used to house the atomizing coil. The oil outlet penetrates the bottom wall of the second groove and communicates with the first groove, guiding the oil in the storage chamber to the atomizing coil for heating and atomization. The vent on the bracket body connects the storage chamber to the external environment. As the atomizing coil continuously consumes the oil in the storage chamber, external air can enter the storage chamber through the vent, maintaining a dynamic pressure balance between the storage chamber and the external environment, improving oil extraction efficiency, and enhancing the stability of the atomizer. Furthermore, only the vent on the bracket is needed to improve oil extraction efficiency without requiring additional parts for a venting structure, thus reducing production costs.

[0034] See Figure 1 and Figure 2 and Figure 8 An embodiment of this application provides an atomizing bracket, including a bracket body 1, which is installed inside an oil cup 2. The bracket body 1 has a first groove 110, a second groove 120, an oil outlet 130, and a ventilation hole 140. The first groove 110 communicates with the liquid storage chamber 210 of the oil cup 2, the second groove 120 is used to install the atomizing core 3, and the oil outlet 130 penetrates the bottom wall of the second groove 120 and communicates with the first groove 110. The oil in the liquid storage chamber 210 can be guided to the atomizing core 3 through the first groove 110 and the oil outlet 130 for heating and atomization. The ventilation hole 140 is used to connect the liquid storage chamber 210 with the external environment so that external air can enter the liquid storage chamber 210 through the ventilation hole 140.

[0035] The aforementioned atomizing bracket includes a bracket body 1, which is installed inside the oil cup 2. The bracket body 1 has a first groove 110, a second groove 120, an oil outlet 130, and a ventilation hole 140. The first groove 110 communicates with the liquid storage chamber 210 of the oil cup 2, and the second groove 120 is used to install the atomizing core 3. The oil outlet 130 penetrates the bottom wall of the second groove 120 and communicates with the first groove 110, enabling the oil in the liquid storage chamber 210 to flow to the atomizing core 3 for heating and atomization. The ventilation hole 140 on the bracket body 1 connects the liquid storage chamber 210 with the external environment. When the atomizing core 3 continuously consumes the oil in the liquid storage chamber 210, external air can enter the liquid storage chamber 210 through the ventilation hole 140, so that the liquid storage chamber 210 maintains a dynamic air pressure balance with the external environment, improving the oil output efficiency and enhancing the stability of the atomizer operation. In addition, the oil discharge efficiency can be improved simply by opening a vent hole 140 on the bracket, without the need for additional parts to set up a venting structure, thus reducing production costs.

[0036] It should be noted that the atomizing bracket in this application is used in an atomizer, and the mist generated in the atomizer can be inhaled by the user.

[0037] Further, see Figure 2To facilitate the extraction of atomized aerosol from the second groove 120 for user inhalation, in one embodiment, a first through hole 150 is provided at one end of the support body 1 in a first direction. One end of the first through hole 150 in the first direction communicates with the second groove 120, and the other end communicates with the air outlet channel 220 of the oil cup 2. The first direction is parallel to the axial direction of the support body 1. That is, after the atomizing core 3 heats the oil, it generates atomized aerosol in the second groove 120. The atomized aerosol can flow directionally into the air outlet channel 220 of the oil cup 2 through the first through hole 150, and is ultimately delivered to the mouthpiece for user inhalation. The second groove 120, acting as an atomizing chamber and communicating with the first through hole 150, allows the atomized aerosol to quickly enter the air delivery path, reducing the residence time of smoke in the second groove 120, effectively improving the inhalation response speed and the stability of smoke output, and ensuring the consistency of smoke volume and taste during continuous inhalation.

[0038] It should be noted that the first direction (the X-axis direction in the figure) is parallel to the axial direction of the bracket body 1. Furthermore, in some embodiments, the oil outlet 130 and the vent 140 are located on opposite sides of the first through hole 150 to avoid the distance between the oil outlet 130 and the vent 140 being too close, thus reducing the impact of the vent 140 on the oil outlet 130. If the distance between the oil outlet 130 and the vent 140 is too close, under the user's suction, the high-speed airflow will wash away the oil guide interface at the oil outlet 130, affecting the stability of the oil supply. The shape of the vent 140 can be circular, polygonal, or irregular, such as... Figure 1 , Figure 2 As shown, in one embodiment, the ventilation hole 140 is circular in shape, reducing the difficulty of manufacturing. The shape of the ventilation hole 140 can be adaptively adjusted according to actual ventilation requirements.

[0039] Furthermore, in some embodiments, the cross-section of the first through hole 150 is D-shaped, such as... Figure 2 As shown, the first through hole 150 includes an arc-shaped wall 151 and a flat wall 152. The flat wall 152 is flush with the end face of the oil guide 31 of the atomizing core 3 away from the bottom wall of the second groove 120. That is, the flat wall 152 and the end face of the oil guide 31 of the atomizing core 3 away from the bottom wall of the second groove 120 are on the same vertical plane, so as to shield the oil guide 31 in the first direction, which can reduce the risk of oil on the oil guide 31 splashing into the air outlet channel 220.

[0040] Further, see Figure 2The second groove 120 serves as an atomizing chamber. During the process of heating and atomizing the oil within the second groove 120, the atomizing core 3 needs to continuously replenish air to form a complete airflow circulation. To ensure smooth gas exchange between the second groove 120 and the external environment and fully meet the air intake requirements for atomization, in some embodiments, the support body 1 is provided with an air exchange channel 160. The air exchange channel 160 is connected to the end of the second groove 120 away from the first through hole 150 in a first direction. The air exchange channel 160 is used to communicate with the external air, providing a stable external air intake path for the second groove 120.

[0041] Furthermore, see Figure 2 To improve the ventilation efficiency within the second groove 120, in one embodiment, the projection of the ventilation channel 160 on a projection plane perpendicular to the first direction is a curved or polygonal structure with alternating concave and convex shapes. For example... Figure 2 As shown, the opening of the air exchange channel 160 has a serrated structure, forming multiple air exchange gaps at the bottom of the atomizing core 3. This effectively increases the air exchange area and improves the air exchange efficiency of the atomizing core 3. Furthermore, the multiple air exchange gaps allow air to diffuse evenly across the entire heating surface of the atomizing core 3, improving the uniformity of oil atomization and the quality of the vapor. Moreover, the multiple air exchange gaps prevent the air intake from failing due to condensation or leaked oil clogging a single gap, effectively improving the reliability of the airflow path and its long-term stability.

[0042] Further, see Figure 3 and Figure 4 Because the atomized aerosol easily condenses when cooled in the first through-hole 150 and the air outlet channel 220, forming condensate, if the condensate continues to accumulate in the air outlet channel 220, it can easily be inhaled into the user's mouth by the suction airflow, causing an unpleasant taste, choking, and other adverse experiences. To directionally recover the condensate and prevent its accumulation in the air outlet channel 220, in one embodiment, a return channel 170 is provided on the support body 1. One end of the return channel 170 is connected to the first through-hole 150, and the other end is connected to the second groove 120. The air outlet channel 220 is located above the return channel 170. The condensate generated in the air outlet channel 220 and the first through-hole 150 can flow into the second groove 120 through the return channel 170 under gravity, enabling the secondary use of the condensate and reducing oil loss. In addition, an oil-absorbing cotton is provided under the bracket body 1 in the atomizer to absorb the condensate, which can further prevent the condensate from spreading and leaking into the assembly gaps around the bracket body 1 and the electrode 33 connection area of ​​the atomizing core 3, thus avoiding electrical failure or appearance pollution.

[0043] Further, see Figure 2 and 8In this application, the support body 1 can be sealed and fitted with the internal structure of the oil cup 2 to jointly enclose and form a liquid storage cavity 210, while simultaneously separating the liquid storage cavity 210 from the vent channel 220. In one embodiment, the outer peripheral wall of the support body 1 has a first annular sealing portion 12, and the side of the support body 1 facing the opening of the first groove 110 is provided with a second annular sealing portion 13, and the first through hole 150 is located inside the second annular sealing portion 13; the oil cup 2 includes a first annular wall 21 and a second annular wall 22 located inside the first annular wall 21; wherein, the outer wall of the first annular sealing portion 12 is used to abut and seal against the inner wall of the first annular wall 21, and the inner wall of the second annular sealing portion 13 is used to abut and seal against the outer wall of the second annular wall 22, so that a liquid storage cavity 210 is formed inside the oil cup 2. Through the coordinated operation of two annular sealing structures, an independent and sealed liquid storage chamber 210 is formed inside the oil cup 2, which simultaneously isolates the liquid storage chamber 210 from the air outlet channel 220, preventing unatomized oil from directly entering the air outlet channel 220 and affecting the suction experience. Furthermore, the two annular seals are integrated into the bracket body 1, eliminating the need for additional independent seals and reducing production costs.

[0044] Furthermore, such as Figure 8 As shown, in order to restrict the gas path entering the liquid storage chamber 210 through the ventilation hole 140, in one embodiment, the atomizing component further includes a flow guide 4. The flow guide 4 is disposed in the second groove 120 and abuts against the oil guide 31 and the first annular wall 21. The flow guide 4 has a flow channel 41, which is connected to the external environment. When the user inhales, the external gas enters the liquid storage chamber 210 through the ventilation hole 140 via the flow channel 41 (the dashed arrow in the figure indicates the gas flow path). The external air enters the liquid storage chamber 210 through a specific path, improving the stability of the gas pressure balance in the liquid storage chamber 210. The flow guide 4 can be removed or added according to the gas pressure balance requirements of the liquid storage chamber 210.

[0045] Further, see Figure 1 To increase the volume of the liquid storage chamber 210, in some embodiments, an oil inlet notch 180 is provided on the outer peripheral wall of the support body 1, and the oil inlet notch 180 communicates with the first groove 110. Providing the oil inlet notch 180 reduces the volume occupied by the support body 1 within the liquid storage chamber 210, thereby increasing the volume of the liquid storage chamber 210. Furthermore, the communication between the oil inlet notch 180 and the first groove 110 reduces the obstruction of the oil by the outer peripheral wall of the support body, optimizes the oil supply path, and further improves the stability of the oil supply from the atomizing core 3.

[0046] Furthermore, in some other embodiments, the support body 1 and the oil cup 2 are further fixed by ultrasonic welding. In order to increase the welding strength between the support body 1 and the oil cup 2, the oil inlet notch 180 can be removed to increase the contact area between the support body 1 and the inner wall of the oil cup 2. Whether or not to set the oil inlet notch 180 can be adaptively adjusted according to the actual application requirements of the support body 1.

[0047] Furthermore, in some embodiments, the outer peripheral wall of the support body 1 is provided with a plurality of condensation grooves 11, which are used to store condensate. Figure 1 and Figure 2 As shown, multiple condensation grooves 11 are symmetrically arranged on opposite sides of the second groove 120 to store some of the condensate that condenses on the bracket body 1. This increases the amount of condensate stored inside the atomizer, thereby reducing the frequency of condensate cleaning and improving the user experience. In addition, the bracket body can be injection molded, and the condensation grooves 11 can also reduce the amount of material used in the bracket body, thus reducing the production cost of the atomizer.

[0048] Furthermore, such as Figure 2 As shown, in some embodiments, to control the output of oil in the reservoir 210 and the oil supply to the atomizing core 3, multiple oil outlets 130 are provided. These multiple oil outlets 130 are spaced apart in a second direction (the Y-axis direction in the figure), which is perpendicular to the axial direction of the support body 1. The dispersed arrangement of multiple oil outlets 130 in the second direction allows the oil in the reservoir 210 to be supplied to multiple areas of the atomizing core 3 simultaneously from multiple points, expanding the oil supply coverage, improving the uniformity of oil intake at the heating end face of the atomizing core 3, and avoiding problems such as dry burning and scorching caused by insufficient local oil supply. Furthermore, by adjusting the number and opening area of ​​the oil outlets 130, it can be adapted to meet the oil consumption needs under different atomization powers.

[0049] Furthermore, such as Figure 2 As shown, in order to increase the oil intake of the atomizing core 3, in one embodiment, the oil outlet 130 has a strip-shaped hole structure, and the length direction of the oil outlet 130 is parallel to the axial direction of the support body 1. By adopting a strip-shaped hole structure with the length direction parallel to the axial direction, the opening area of ​​the oil outlet 130 can be precisely controlled by adjusting the axial length of the strip-shaped hole to adapt to oils of different viscosities and diverse atomization conditions.

[0050] Based on the same concept, this application also provides an atomizer, including an atomizing core 3 and an atomizing bracket. (See also...) Figure 5 , Figure 6 and Figure 7The atomizing core 3 includes an oil guide 31 and a heating element 32. The oil guide 31 is installed in the second groove 120 and is used to guide the oil in the reservoir 210. The heating element 32 is attached to the side of the oil guide 31 facing away from the bottom wall of the second groove 120 and is used to atomize the oil in the oil guide 31. The oil guide 31 can be made of absorbent cotton. Furthermore, in order to reduce the volume of the heating element 32 and facilitate its fit with the absorbent cotton, the heating element 32 is made of heating wire. The main body of the heating wire has a mesh structure that can completely cover the heating surface of the absorbent cotton. The bottom of the heating wire is also provided with a connecting seat for connecting to the electrode 33 of the atomizing core 3. When the atomizer of this application is applied to an electronic cigarette, the electronic cigarette also includes a battery main unit. The battery main unit is connected to the electrode 33 and can supply power to the heating wire to atomize the oil in the oil guide 31.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
