[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] First, see Figures 1 to 3The present application provides an atomizer 100, including an oil cup 10, a flexible bracket 20, an atomizing core 30 and a fixing member 40. The oil cup 10 includes a shell 11 and a vent pipe 12 disposed in the shell 11. One end of the shell 11 is connected to the vent pipe 12, and the other end is set as an open end. A liquid storage chamber 13 is formed between the outer peripheral side of the vent pipe 12 and the inner wall of the shell 11. The flexible bracket 20 is set at the open end. The flexible bracket 20 includes a main body 23 and a first sealing part 21 and a second sealing part 22 disposed on the main body 23. The first sealing part 21 is sealed and connected to the vent pipe 12, and the second sealing part 22 is sealed and connected to the inner wall of the shell 11. The main body 23 is provided with a accommodating chamber 231 and an oil lowering structure. The accommodating chamber 231 is connected to the liquid storage chamber 13 through the oil lowering structure. The accommodating chamber 231 passes through one of the side surfaces of the main body 23, and a mounting window 232 is formed on the side surface. The atomizer core 30 and the fixing member 40 are sequentially arranged in the accommodating cavity 231 , a portion of the fixing member 40 is against the atomizer core 30 , the fixing member 40 and the atomizing surface of the atomizer core 30 form an atomizing cavity 41 , the atomizing cavity 41 is connected to the ventilation pipe 12 , and the surface of the fixing member 40 away from the atomizer core 30 is sealed with the installation window 232 .
[0031] By utilizing the elasticity of the flexible bracket 20, the flexible bracket 20 can have a certain deformation ability, which helps the flexible bracket 20 to fit with the oil cup 10, thereby achieving a sealing effect. Specifically, the first sealing portion 21 of the flexible bracket 20 is sealed and connected to the vent pipe 12, and the second sealing portion 22 is connected to the inner wall of the shell 11, so as to achieve a sealed installation of the flexible bracket 20 and the oil cup 10, prevent the atomized medium in the liquid storage chamber 13 from leaking, and avoid the atomized medium from leaking from the matching position of the oil cup 10 and the flexible bracket 20, thereby improving the anti-leakage effect. In this way, the atomizer 100 does not need to be additionally provided with a seal (such as a sealing ring or other structure), thereby reducing the number of parts of the entire atomizer 100. On the one hand, it can reduce the number of matching points between the various parts, reduce the risk of oil leakage, and improve the reliability of the atomizer 100. On the other hand, it can simplify the internal structure of the atomizer 100 and improve assembly efficiency.
[0032] By setting the installation window 232 on the side of the flexible bracket 20, it is convenient to assemble the atomizer core 30 and the fixing member 40 into the accommodating chamber 231 through the installation window 232 in sequence. The fixing member 40 can not only encapsulate the atomizer core 30 in the accommodating chamber 231 to achieve the installation and fixation of the atomizer core 30, but also seal the installation window 232 to prevent the atomized medium from penetrating into the accommodating chamber 231 from the installation window 232, and prevent the atomized aerosol from leaking from the installation window 232 to ensure that the gas flows out of the vent pipe 12. The seal between the periphery of the fixing member 40 and the installation window 232 can also utilize the elastic characteristics of the flexible bracket 20, so that the two can be closely matched to achieve sealing, without the need to additionally set a sealing member to seal the installation window 232, further reducing the number of parts and improving the sealing effect. Exemplarily, the periphery of the fixing member 40 is connected with the installation window 232 by interference fit, so that the fixing member 40 itself can achieve self-fixation, and there is no need to additionally set other structures to fix the fixing member 40, thereby simplifying the assembly steps and improving the assembly efficiency.
[0033] Optionally, the atomizing core 30 includes a heating element 31 and an oil-conducting body 32, the oil-conducting body 32 is used to absorb and store the atomizing medium from the oil-passing hole, the heating element 31 can be arranged on the surface or inside of the oil-conducting body 32, and the heating element 31 can heat the atomizing medium in the oil-conducting body 32 and form an aerosol after being energized. Exemplarily, the oil-conducting body 32 can be made of porous ceramics, porous glass, oil-conducting cotton, hemp and other materials. The surface of the atomizing core 30 that produces the aerosol is the atomizing surface, and the fixing member 40 or the atomizing core 30 can be arranged at intervals to form an atomizing chamber 41, and the atomizing chamber 41 has a certain space for the aerosol to flow. Exemplarily, a part of the fixing member 40 can be concave to form the atomizing chamber 41, which helps to set the atomizing surface as a plane and simplify the setting of the atomizing core 30. The atomizing chamber 41 is connected to the vent pipe 12 to transport the aerosol to the nozzle end of the oil cup 10. The atomizer 100 further includes a base 40 and an electrode 60. The base 40 is mounted on the bottom of the flexible bracket 20 to encapsulate the flexible bracket 20 in the housing 11. The electrode 60 is disposed on the base 40 and penetrates the flexible bracket 20 to achieve electrical connection with the heating element 31.
[0034] In some embodiments, at least a portion of the side of the main body 23 away from the accommodating chamber 231 is spaced apart from the inner wall of the shell 11 to form a lower oil channel 234, the lower oil channel 234 is connected to the liquid storage chamber 13, the lower oil structure includes a lower oil hole 233, the side of the main body 23 away from the accommodating chamber 231 is formed as a lower oil surface, and the lower oil hole 233 is arranged on the lower oil surface. The lower oil channel 234 and the lower oil hole 233 can be used to connect the liquid storage chamber 13 with the accommodating chamber 231, the atomizing medium in the liquid storage chamber 13 flows to the lower oil channel 234 through the open end of the oil cup 10, and enters the accommodating chamber 231 through the lower oil hole 233 under the guidance of the lower oil surface, and the atomizing core 30 in the accommodating chamber 231 can heat the atomizing medium and atomize it to form an aerosol for the user to inhale. The accommodating chamber 231 and the oil lowering channel 234 are respectively arranged on two sides of the main body 23, so that the accommodating chamber 231 and the oil lowering channel 234 can independently realize their functions without interfering with each other. The accommodating chamber 231 and the oil lowering channel 234 are arranged opposite to each other in the main body 23, which can make full use of the space of the main body 23 and make the structure inside the atomizer 100 more compact.
[0035] For example, the main body 23 can be set inwardly through a part of the structure, and a certain space can be formed between the concave part and the inner wall surface of the shell 11, and the atomized medium uses the space to flow to the lower oil hole 233, and the space is formed as the lower oil channel 234. Of course, in other examples, the inner wall surface of the shell 11 can also be set to bulge outward, so that there is a certain space between the inner wall surface of the shell 11 and the main body 23 of the flexible bracket 20, and the lower oil channel 234 is formed by using the space, which is not limited here.
[0036] In order to balance the air pressure in the liquid storage chamber 13 so that the atomized medium can flow out continuously and automatically, please refer to Figures 3 to 5In some embodiments, the lower oil surface is further provided with an air return hole 2341, and the air return hole 2341 is connected to the accommodating chamber 231. Along the oil discharge direction, the air return hole 2341 is located upstream of the lower oil hole 233. The air return hole 2341 enables air to enter the liquid storage chamber 13, so that the liquid storage chamber 13 can achieve a balance of internal and external air pressures by replenishing air after a portion of the atomized medium flows out. After the gas enters the air return hole 2341, it will flow in the liquid atomized medium in the form of bubbles until the liquid surface of the atomized medium emerges. During the flow of bubbles, in order to avoid problems such as bubbles blocking the lower oil hole 233 and causing poor oil discharge, a certain distance can be set between the air return hole 2341 and the lower oil hole 233, and the bubbles avoid the lower oil hole 233 during the movement. Optionally, the air return hole 2341 is arranged upstream of the lower oil hole 233 along the oil discharge direction. In this way, since the moving direction of the air bubbles is opposite to the oil discharge direction, the air bubble moving path does not pass through the lower oil hole 233, thereby avoiding the problem of the air bubbles blocking the lower oil hole 233 and ensuring that the lower oil hole 233 is unobstructed. It can be understood that the oil discharge direction is related to the orientation of the flexible bracket 20 in the use state, and the upstream and downstream position relationship is relative to the position of the lower oil hole 233. For example, in this example, when the atomizer 100 is used, the flexible bracket 20 is arranged in a roughly vertical direction, and the atomized medium flows from top to bottom along the lower oil channel 234 to the lower oil hole 233. Therefore, the air return hole 2341 can be arranged above the lower oil hole 233 (including directly above, not directly above, such as Figure 6 As shown), the bubbles will not pass through the lower oil hole 233 when flowing upward, thereby avoiding clogging of the lower oil hole 233.
[0037] In order to further ensure that the bubbles can avoid the lower oil hole 233 when flowing, in some embodiments, a retaining wall structure is protruded from the periphery of the air return hole 2341, and the retaining wall structure is used to guide the bubbles to flow in a direction away from the lower oil hole 233. The retaining wall structure is protruded from the periphery of the air return hole 2341, so that after bubbles are formed in the air return hole 2341, the bubbles can change the direction of movement under the blocking effect of the retaining wall structure, so as to move in a direction away from the lower oil hole 233, further improving the patency and reliability of the oil supply from the lower oil hole 233.
[0038] Optionally, the retaining wall structure can specifically achieve a blocking effect by setting steps. In one example, a first step structure 2343 is provided on the lower oil surface. Along the height direction of the lower oil channel 234, the first step structure 2343 is arranged on the lower side of the return air hole 2341, and the first step structure 2343 is formed as a retaining wall structure. In this way, the first step structure 2343 can block the bubbles from moving downward, thereby guiding the bubbles to flow upward to avoid the position of the lower oil hole 233. Even when the atomizer 100 is inverted, the first step can also block the bubbles from approaching the lower oil hole 233 to ensure that the lower oil hole 233 is not blocked. In addition, the wall thickness of the main body 23 at the position of the first step structure 2343 is increased, which is beneficial to improve the strength of the flexible bracket 20 and reduce the risk of deformation of the flexible bracket 20. In another example, the return air hole 2341 and the lower oil hole 233 are connected in the width direction of the lower oil surface (for example Figure 4 The second step structure 2344 is formed as a retaining wall structure. In this way, when the atomizer 100 is placed horizontally, the second step structure 2344 can block the air bubbles from approaching the lower oil hole 233, thereby guiding the air bubbles to move in a direction away from the lower oil hole 233. The above two steps can be set at the same time, or only one of them can be set separately, which is not limited here. When the two steps are set at the same time, no matter what posture the atomizer 100 is placed in, the air bubbles can move in a direction away from the lower oil hole 233 under the simultaneous guidance of the first step structure 2343 and the second step structure 2344.
[0039] In some embodiments, the lower oil surface includes an oil guide surface 2340, and the oil guide surface 2340 is inclined relative to the axis of the vent pipe 12. The inclined oil guide surface 2340 has a slope effect, and the atomized medium can flow along the slope to the lower oil hole 233, thereby improving the fluidity and continuity of the oil discharge.
[0040] Since the main body 23 of the flexible bracket 20 is provided with a receiving chamber 231, the wall thickness of the main body 23 at this position is reduced accordingly, and there is a risk of reduced strength. In order to avoid the problem of easy deformation due to insufficient wall thickness of the receiving chamber 231, and to avoid the lower oil surface being squeezed and deformed after the fixing member 40 abuts against the atomizer core 30, in some embodiments, a reinforcement structure is also provided on the back of the receiving chamber 231. Specifically, a transition slope 2345 is also provided between the outer peripheral side wall of the first sealing portion 21 and the oil guide surface 2340. The transition slope 2345 is inclined relative to the axis of the ventilation pipe 12, and the inclination direction of the transition slope 2345 is opposite to the inclination direction of the oil guide surface 2340. The transition slope 2345 and the oil guide surface 2340 constitute a reinforcement structure, and the reinforcement structure is located on the back of the receiving chamber 231. The oil guide surface 2340, the transition slope 2345, and the inner wall surface of the housing 11, which are inclined in opposite directions, form a triangular structure, which helps to improve the structural strength of the main body 23 of the flexible bracket 20. Figure 4 The wall thickness of the reinforcing structure decreases first and then increases, thereby forming a certain arch structure, improving the structural strength of the back of the accommodating chamber 231, preventing the fixing member 40 from squeezing the bottom wall of the accommodating chamber 231 and deforming it when abutting against the atomizer core 30, avoiding the problem of sealing failure caused by deformation of the accommodating chamber 231, ensuring that the lower oil surface is not squeezed and allowing the lower oil channel 234 to have enough oil discharge space to ensure the smoothness of oil discharge.
[0041] In some embodiments, the first sealing portion 21 includes a sealing step, the sealing step is arranged at the top of the main body 23, a part of the vent pipe 12 is inserted into the sealing step, and a plurality of reinforcing portions 211 are arranged at intervals on the periphery of the sealing step. By inserting a part of the vent pipe 12 into the sealing step, the contact area between the vent pipe 12 and the sealing step can be increased, and the sealing effect can be improved. The reinforcing portion 211 can improve the structural strength of the sealing step and avoid the sealing failure caused by the deformation of the sealing step. Exemplarily, the reinforcing portion 211 can be arranged as a reinforcing block protruding from the outer peripheral side or top surface of the sealing step to increase the structural thickness of the part. Optionally, one of the reinforcing ribs is arranged in the direction of the transition slope 2345 extending toward the liquid storage chamber 13, and is formed as a part of the transition slope 2345, and the reinforcing rib can be raised and abutted against the inner wall surface of the shell 11 to improve the strength of the first sealing portion 21 and the transition slope 2345.
[0042] In some embodiments, the second sealing portion 22 is disposed at the bottom of the main body 23, and the second sealing portion 22 includes a sealing rib arranged around the outer peripheral side of the main body 23, and the sealing rib is sealed and connected to the inner wall surface of the housing 11. The sealing rib can be convexly arranged on the outer periphery of the main body 23 to increase the contact area between the main body 23 and the inner wall of the housing 11, thereby improving the sealing effect. Optionally, the sealing rib is arranged circumferentially along the outer periphery of the main body 23, and a plurality of sealing ribs can be arranged, and the plurality of sealing ribs are distributed and arranged along the axial direction of the main body 23, thereby further improving the sealing effect.
[0043] Optionally, the first sealing portion 21 and the second sealing portion 22 are integrally formed in the main body 23, so that the flexible bracket 20 itself can be sealed and connected to the ventilation pipe 12 and the shell 11 of the oil cup 10 respectively, without the need for an additional sealing structure, thereby reducing the number of parts, and improving the sealing reliability and assembly efficiency of the atomizer 100.
[0044] In some embodiments, please refer to Figure 6 The main body 23 includes a mounting portion 235 and a bracket portion 236. The mounting portion 235 is arranged inside the bracket portion 236. A gap 2351 is arranged between the outer periphery of the mounting portion 235 and the inner wall of the bracket portion 236. The accommodating cavity 231 is arranged on the mounting portion 235. When the fixing member 40 is installed in the accommodating cavity 231, the side wall of the mounting portion 235 can be deformed toward the gap 2351. By utilizing the gap 2351, the size of the accommodating cavity 231 can be set slightly smaller than the size of the fixing member 40, and the fixing member 40 can be interference-fitted with the accommodating cavity 231 to improve the sealing effect. When the fixing member 40 is assembled in the accommodating cavity 231, the slight deformation of the side wall of the mounting portion 235 can make it bend toward the gap 2351. The squeezing force of the outer periphery of the fixing member 40 on the side wall of the mounting portion 235 and the elastic force of the mounting portion 235 itself interact with each other, so that the two can achieve the purpose of sealing.
[0045] In the second aspect, the present application further provides an electronic atomization device, which includes the atomizer 100 provided in the first aspect and a power supply assembly (not shown), which is connected to the atomizer 100. Exemplarily, the power supply assembly can be a battery rod, which can be connected to the atomizer 100 by mutual plugging, threading or snapping, and the power supply assembly is used to provide electrical energy for the use of the atomizer.
