Abstract
Description
Technical Field
[0001] This utility model belongs to the field of atomization technology, and in particular relates to an atomizer. Background Technology
[0002] An atomizer is a device that atomizes a liquid to generate an aerosol. An atomizer generally includes a shell, a liquid reservoir, an atomizing chamber, a liquid guiding structure, and an atomizing core. The liquid reservoir and atomizing chamber are formed inside the shell. The liquid guiding structure directs the liquid from the liquid reservoir to the atomizing core, which heats the atomizing matrix to generate an aerosol. In related technologies, when large-capacity atomizers are manufactured and shipped from ordinary areas, the internal and external air pressures are equal. However, when transported to high-altitude areas and used until a certain amount of liquid remains, leakage may occur due to pressure imbalance. Furthermore, when using the atomizer in cold regions, the gas in the liquid reservoir may increase the pressure inside the oil cup due to thermal expansion and contraction, leading to leakage. Utility Model Content
[0003] The technical objective of this utility model is to provide an atomizer that aims to solve the problem of leakage when atomizers are used in high-altitude or cold regions.
[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: Firstly, an atomizer is provided, comprising: an oil cup, an isolation tube, an integrated cotton, and an atomizing core; the top of the oil cup is provided with an air outlet communicating with the atmosphere, and the bottom of the oil cup is provided with a fixing seat; the isolation tube is fixed inside the oil cup, and the isolation tube, the oil cup, and the fixing seat together form a liquid storage chamber, and the isolation tube also has mutually spaced air exchange ports and liquid guide ports, with the air exchange ports positioned higher than the liquid guide ports in the axial direction; the integrated cotton is fixed inside the isolation tube, and the integrated cotton defines an air outlet channel that extends through both ends in the axial direction and communicates with the air outlet, and an air exchange channel extending in the axial direction and communicating with the air exchange port is formed between the outer periphery of the integrated cotton and the isolation tube, and an air passage connecting the air exchange channel and the air outlet is also provided between the top of the integrated cotton and the oil cup; and the atomizing core is disposed within the air outlet channel of the integrated cotton.
[0005] Furthermore, the isolation pipe has at least two mutually spaced air vents along its axial direction.
[0006] Furthermore, an elastomer is connected between the oil cup and the inner top of the isolation tube. A spring is provided on the elastomer, and among the multiple air exchange ports, some air exchange ports located near the air outlet are blocked by the spring.
[0007] Furthermore, the integrated cotton includes a first section and a second section arranged along the axial direction. The first section is located at the end near the air outlet, and the density of the first section is less than that of the second section.
[0008] Furthermore, it also includes a support tube, which abuts against the side of the integrated cotton away from the isolation tube, and the support tube encloses to form at least part of the air outlet channel, with the atomizing core disposed inside the support tube.
[0009] Furthermore, a liquid-blocking component is fixed at the end of the support tube away from the air outlet, and an atomizing chamber is provided inside the atomizing core. An air passage hole communicating with the atomizing chamber is opened on the liquid-blocking component; a liquid guiding hole is opened on the support tube corresponding to the liquid-blocking component, and a flow guiding part is formed at the end of the liquid-blocking component near the atomizing core. The flow guiding part gradually slopes downward from the inside of the end face of the liquid-blocking component to the edge.
[0010] Furthermore, the middle area of the liquid-blocking component near the atomizing core also has an upwardly protruding oil-avoiding structure.
[0011] Furthermore, the support tube has multiple spaced liquid guiding holes.
[0012] Furthermore, the diameter of the return air hole is 0.5–1.0 mm.
[0013] Furthermore, the atomizer also includes a battery assembly that is electrically connected to the atomizer core.
[0014] Compared with existing technologies, the atomizer of this invention has the following advantages: An air exchange channel is opened on the outer periphery of the integrated cotton, and a connecting return air hole is opened on the isolation tube. The top of the integrated cotton and the oil cup form an air passage connecting the air exchange channel and the air outlet. This design allows the atomizer to maintain internal and external air pressure balance even when the e-liquid is consumed to a certain extent. It also prevents leakage caused by increased air pressure in the reservoir when the ambient temperature drops suddenly. In other words, an air exchange path is formed between the oil cup, isolation tube, and integrated cotton, connecting the reservoir to the outside. During use, the gas in the reservoir can enter the air exchange channel along the return air hole, and then reach the outside along the air passage and the air outlet. This achieves the purpose of automatically maintaining air pressure balance between the reservoir and the outside, effectively preventing leakage caused by external factors such as high altitude or sudden temperature changes.

[0024] Example:
[0025] like Figure 1-5As shown, in this embodiment, the atomizer includes: an oil cup 1, an isolation tube 2, an integrated cotton 3, and an atomizing core 4; the top of the oil cup 1 is provided with an air outlet 13 communicating with the atmosphere, and the bottom of the oil cup 1 is provided with a fixing seat 12; the isolation tube 2 is fixed inside the oil cup 1, and the isolation tube 2, the oil cup 1, and the fixing seat 12 together form a liquid storage chamber 11. The isolation tube 2 also has mutually spaced air exchange ports 21 and liquid guide ports 22. In the axial direction, the position of the air exchange port 21 is higher than that of the liquid guide port 22; the integrated cotton 3 is fixed inside the isolation tube 2, and the integrated cotton 3 defines an air outlet channel 32 that runs through both ends of the axial direction and communicates with the air outlet 13. An air exchange channel extending in the axial direction and communicating with the air exchange port 21 is formed between the outer periphery of the integrated cotton 3 and the isolation tube 2. An air passage 14 communicating with the air exchange channel and the air outlet 13 is also provided between the top of the integrated cotton 3 and the oil cup 1; the atomizing core 4 is disposed in the air outlet channel 32 of the integrated cotton 3.
[0026] Specifically, during the process of the e-liquid (e-liquid) reaching the atomizer core 4 from the reservoir 11, an integrated cotton 3 is used to lock in the e-liquid, resulting in good e-liquid retention. Simultaneously, an air exchange groove 31 is formed on the outer periphery of the integrated cotton 3. The air exchange groove 31 and the inner wall of the isolation tube 2 enclose the aforementioned air exchange channel. A return air hole is formed on the isolation tube 2, and the top of the integrated cotton 3 and the e-liquid cup 1 enclose an air passage 14 connecting the air exchange groove 31 and the air outlet 13. This design allows the atomizer to maintain internal and external air pressure balance even when the e-liquid is consumed to a certain extent. To prevent the increase in air pressure inside the liquid storage chamber 11 when the ambient temperature drops suddenly, a ventilation path is formed between the oil cup 1, the isolation tube 2, and the integrated cotton 3, connecting the liquid storage chamber 11 to the outside. During use, the gas in the liquid storage chamber 11 can enter the ventilation groove 31 along the ventilation port 21, and then reach the outside along the air passage 14 and the air outlet 13. This achieves the purpose of automatically maintaining the air pressure balance between the liquid storage chamber 11 and the outside, effectively avoiding leakage caused by external factors such as high altitude or sudden temperature changes.
[0027] In this embodiment, the isolation tube 2, together with the inner wall of the oil cup 1 and the top of the fixing seat 12, defines the liquid storage chamber 11. The liquid storage chamber 11 can be used to store atomizing liquid. The liquid guide port 22 opened on the isolation tube 2 can guide the atomizing liquid in the liquid storage chamber 11 to the integrated cotton 3. Thus, the integrated cotton 3 can further transport the atomizing liquid downward to the atomizing core 4, so that the atomizing core 4 can heat and atomize the atomizing liquid to form an aerosol.
[0028] In this embodiment, the isolation tube 2 has at least two mutually spaced vents 21 along the axial direction. That is, multiple mutually spaced vents 21 are arranged along the axial direction. This stepped vent design ensures that no matter how much atomizing liquid is consumed, there is always a vent 21 above the liquid surface, thereby effectively balancing the air pressure above the liquid surface in the storage chamber 11 and outside the atomizing chamber 41, achieving effective leak prevention. In this embodiment, the inner wall of the isolation tube 2 and the venting groove 31 enclose a venting channel connecting the vents 21 and the air passage 14. One or more venting grooves 31 can be symmetrically arranged, that is, one or more venting channels can be symmetrically arranged. When multiple venting channels are provided, each venting channel can be connected to multiple spaced vents 21, which is not limited here.
[0029] In this embodiment, an elastic body 5 is connected between the inner top of the oil cup 1 and the isolation tube 2. A spring plate 51 is provided on the elastic body 5. Among the multiple air exchange ports 21, some air exchange ports 21 located near the air outlet 13 are blocked by the spring plate 51. Specifically, the elastic body 5 can be a silicone sealant. A limiting part extending downwards from the top is provided inside the oil cup 1, and the air outlet 13 passes through the limiting part. The elastic body 5 abuts against the inner top wall of the isolation tube 2 and the outer side of the limiting part to ensure the sealing stability between the oil cup 1 and the isolation tube 2. A spring plate 51 is also provided on the bottom side of the elastic body. The spring plate 51 abuts against the inner side of the air exchange port 21 at the top of the isolation tube 2 to act as a one-way valve. It only opens when the gas pressure in the liquid storage chamber 11 is high (i.e., it is pushed open by the gas). This design can further improve the leak-proof effect of the atomizer and effectively balance the internal and external pressure difference of the oil cup 1.
[0030] In this embodiment, the integrated cotton 3 includes a first section 3a and a second section 3b arranged axially. The first section 3a is located near the air outlet 13, and its density is less than that of the second section 3b. Specifically, in the axial direction, the less dense first section 3a is located at the upper end, and the more dense second section 3b is located at the lower end. When the product is inhaled, most of the condensate is concentrated in the first section 3a, and most of the condensate is absorbed by the low-density first section 3a. If the low-density first section 3a becomes saturated, the excess e-liquid will be further absorbed into the high-density second section 3b. Meanwhile, the e-liquid in the second section 3b is constantly being consumed and is in an unsaturated state, so the second section 3b can continuously absorb the e-liquid from the first section 3a. In this way, by absorbing the leaked e-liquid through the first section 3a and then consuming the leaked e-liquid through the second section 3b during inhalation, the leak-proof performance of the atomizer can be further improved.
[0031] In this embodiment, the diameter of the return air hole is 0.5–1.0 mm. For example, the diameter of the return air hole can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc., and is not limited thereto. This embodiment also includes a support tube 6, which abuts against the side of the integrated cotton 3 facing away from the isolation tube 2, and the support tube 6 forms at least a partial air outlet channel 32. The atomizing core 4 is disposed within the support tube 6. Specifically, the integrated cotton 3 is clamped and fixed by the isolation tube 2 and the support tube 6, ensuring the assembly stability of the integrated cotton 3.
[0032] In this embodiment, a liquid-blocking component 7 is fixed at the end of the support tube 6 away from the air outlet 13. An atomizing chamber 41 is provided inside the atomizing core 4. An air passage 71 communicating with the atomizing chamber 41 is provided on the liquid-blocking component 7. A liquid guiding hole 61 is provided on the support tube 6 corresponding to the liquid-blocking component 7. A flow guiding part 72 is formed at the end of the liquid-blocking component 7 near the atomizing core 4. The flow guiding part 72 gradually slopes downward from the inside of the end face of the liquid-blocking component 7 to the edge. In this embodiment, due to the presence of the liquid-blocking component 7, when the liquid leaked from the atomizing core 4 reaches the liquid-blocking component 7, it can flow along the flow guiding part 72 and accumulate between the liquid-blocking component 7 and the support tube 6, or flow back into the integrated cotton 3 through the liquid guiding hole 61 and be reabsorbed and utilized by the integrated cotton 3, thereby preventing the liquid from flowing out.
[0033] In some specific embodiments, the atomizing core 4 includes an oil-guiding cotton abutting against the inner wall of the support tube 6, a heating element fixed to the side opposite to the oil-guiding cotton, and an electrode electrically connected to the heating element. An atomizing chamber 41 is formed inside the heating element. An air inlet can be provided on the fixing base 12, which connects the atomizing chamber 41 and the air outlet channel 32. When the atomizer is working, the atomized liquid in the integrated cotton 3 can pass through the support and reach the heating element along the oil-guiding cotton. After the heating element is energized, it can heat and atomize the atomized liquid to form an aerosol. The generated aerosol mixes with the air entering along the air inlet and the air outlet 71 in the atomizing chamber 41, and then reaches the outside of the atomizer along the air outlet channel 32 and the air outlet 13 for the user to inhale.
[0034] Furthermore, in this embodiment, an upwardly protruding oil-avoiding structure 73 is formed in the middle region of the liquid-blocking member 7 near the atomizing core 4. The presence of the oil-avoiding structure 73 can further guide the leakage, allowing the leakage to be reabsorbed by the integrated cotton 3, preventing the leakage from entering the atomizing chamber 41. In this embodiment, multiple spaced liquid guiding holes 61 are provided on the support tube 6, which is beneficial to further improve the effect of leakage reabsorption.
[0035] In this embodiment, the atomizer also includes a battery assembly 8, which is electrically connected to the atomizing core 4. Specifically, the battery assembly 8 can supply power to the heating element of the atomizing core 4 through electrodes.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
