Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and more particularly to an atomizer and an electronic cigarette having the atomizer. Background Technology

[0002] The atomizer is a crucial component of e-cigarettes, working by heating the absorbed e-liquid to produce vapor. Currently, atomizers on the market generally offer two filling methods: top-filling and bottom-filling. Bottom-filling is more complex, requiring the atomizer to be inverted and the base unscrewed for filling, which is not only cumbersome but also prone to spillage. While top-filling systems offer various designs and are generally more convenient than bottom-filling, they still have drawbacks, remaining somewhat inconvenient to use when filling the atomizer. Summary of the Invention

[0003] This application provides an atomizer and an electronic cigarette having the atomizer to solve the problem of inconvenient liquid filling of the atomizer.

[0004] In a first aspect, this application provides an atomizer, including a housing and a cover. The housing has a liquid storage chamber for storing e-liquid. The top of the housing has an injection hole communicating with the liquid storage chamber. The cover is movably connected to the housing and can block the injection hole. A buckle is detachably installed on the outer periphery of the cover. A retaining part is provided on the outer periphery of the top of the housing. The buckle and the retaining part cooperate to lock the cover closed. The cover can be opened by triggering the buckle or the retaining part to disengage them.

[0005] Furthermore, the cover is rotatably or detachably connected to the housing.

[0006] Furthermore, the buckle is a snap ring structure, which includes a fixing ring fixed to the cover and a hook formed on the fixing ring, the hook cooperating with the holding part to lock it in place.

[0007] Furthermore, a fixing groove is provided around the periphery of the cover, and the fixing ring is locked in the fixing groove.

[0008] Furthermore, the cover is fixed with a hinge, which is arranged opposite to the hanging ear. The outer peripheral wall at the top of the housing has a protrusion, and the hinge is rotatably connected to the protrusion.

[0009] Furthermore, the hinge is integrally connected to the side of the fixing ring opposite the lug, and the fixing ring, the lug, and the hinge are integrally connected to form the snap ring structure.

[0010] Furthermore, the snap ring structure is formed by bending metal wire, and the broken end of the metal wire is located in the middle of the hinge and is rotatably disposed in the protrusion.

[0011] Furthermore, an air outlet is provided at the top of the housing, and a suction nozzle communicating with the air outlet is provided on the cover.

[0012] Furthermore, a sealing element is provided between the cover and the injection hole.

[0013] Secondly, this application provides an electronic cigarette, including the aforementioned atomizer.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The atomizer provided in this application embodiment features a cover movably connected to the housing, a latching element on the cover, and a retaining part on the outer periphery of the top of the housing that engages with the latching element. During use, the cover tightly seals the injection hole, preventing leakage, thanks to the engagement of the latching element and the retaining part. When adding e-liquid to the reservoir, simply triggering the latching element or the retaining part disengages the two, opening the cover and exposing the injection hole for e-liquid injection. After injection, simply closing the cover causes the latching element to engage with the retaining part, sealing the injection hole. This simple operation facilitates easy replenishment of e-liquid into the reservoir through the injection hole, improving the user experience. The atomizer with this structure only requires a latching element on the cover and a retaining part on the outer periphery of the top of the housing, resulting in a rational design, simple assembly, reduced production costs, and increased production efficiency.

[0016] The electronic cigarette using the atomizer described above, as provided in this application embodiment, allows for easy opening of the cover via a movable button and injection of e-liquid into the housing through the filling hole, simplifying operation and improving the user experience. This design results in a rational electronic cigarette structure, simple assembly, reduced production costs, and increased production efficiency. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0032] Example 1

[0033] like Figures 1 to 5 As shown in the figure, this application provides an atomizer, including a housing 1 and a cover 2. The housing 1 is provided with a liquid storage chamber 10 for storing e-liquid. The top of the housing 1 is provided with an injection hole 11 communicating with the liquid storage chamber 10. The cover 2 is movably connected to the top of the housing 1 and can block the injection hole 11. The outer periphery of the cover 2 is provided with a fastener 3, and the outer periphery of the top of the housing 1 is provided with a retaining part 4. The fastener 3 and the retaining part 4 cooperate to lock and close the cover 2. By triggering the fastener 3 or the retaining part 4, the two are disengaged to open the cover 2.

[0034] The atomizer provided in this application embodiment features a cover 2 movably connected to the housing 1, a latching member 3 on the cover 2, and a retaining part 4 on the outer peripheral wall of the top of the housing 1 that movably engages with the latching member 3. During use, the cover 2, under the engaging action of the latching member 3 and the retaining part 4, tightly seals the injection hole 11, preventing leakage. When it is necessary to add e-liquid to the storage chamber 10, simply triggering the latching member 3 or the retaining part 4 disengages them, opening the cover 2 and exposing the injection hole 11 for e-liquid injection. After e-liquid injection, simply closing the cover 2 causes the latching member 3 to engage with the retaining part 4, thus sealing the injection hole 11. This simple operation facilitates easy replenishment of e-liquid into the storage chamber 10 through the injection hole 11, improving the user experience. The atomizer with the above-mentioned structural design only needs to have a buckle 3 on the cover 2 and a retaining part 4 on the outer peripheral wall of the top of the shell 1. In this way, the structural design is reasonable, the assembly is simple, the production cost of the atomizer is reduced, and the production efficiency of the atomizer is improved.

[0035] like Figure 5 and Figure 6As shown, in one embodiment of this application, the housing 1 includes a cylindrical body 12, a first end cap 13, and a second end cap 14. The first end cap 13 and the second end cap 14 are respectively disposed at the two ends of the cylindrical body 12, forming a storage chamber 10 for storing e-liquid. To improve the sealing performance of the connection between the first end cap 13 and the second end cap 14 and the cylindrical body 12, a first sealing element 15 is provided between the first end cap 13 and the cylindrical body 12, and the first end cap 13 is secured to the first end of the cylindrical body 12 by the first sealing element 15. A second sealing element 16 is provided between the second end cap 14 and the cylindrical body 12, and the second end cap 14 is secured to the second end of the cylindrical body 12 by the second sealing element 16. Preferably, both the first sealing element 15 and the second sealing element 16 are silicone sealing rings, which have the advantages of being non-toxic, odorless, chemically stable, and having good sealing performance. Preferably, the cylindrical body 12 is made of glass, which facilitates observation of the amount of e-liquid inside the cylindrical body 12, allowing for the addition of e-liquid according to the amount of e-liquid. In other embodiments, the cylinder 12 may also be made of other transparent tubes.

[0036] like Figure 5 and Figure 7 As shown, specifically, the injection hole 11 is opened on the end wall of the first end cap 13, and a sealing sleeve 17 is provided around the injection hole 11. When the cap 2 is closed, it abuts against the sealing sleeve 17 to seal the injection hole 11 and prevent the liquid from leaking out from the gap of the injection hole 11.

[0037] like Figure 5 and Figure 6 As shown, in one embodiment of this application, the first end cap 13 has an air outlet 130, and the cap 2 has a mouthpiece 5 communicating with the air outlet 130. The air outlet 130 is used to guide the aerosol generated by atomization to the mouthpiece 5 for inhalation. The cylinder 12 has an atomizing core 6, which is immersed in the e-liquid in the liquid storage chamber 10 and generates smoke by heating the absorbed e-liquid. The air inlet end of the atomizing core 6 is installed on the second end cap 14, and the air outlet end of the atomizing core 6 is installed on the first end cap 13 and communicates with the air outlet 130 and the mouthpiece 5.

[0038] In one embodiment of this application, the cover 2 is rotatably connected to the first end cap 13, allowing the cover 2 to be rotated open on the first end cap 13, after which the cover 2 remains connected to the first end cap 13. It is understood that in another embodiment, the cover 2 may also be detachably connected to the first end cap 13, and the cover 2 may be separated from the first end cap 13 after opening. The following description uses the example of the cover 2 being rotatably connected to the first end cap 13.

[0039] like Figure 6 and Figure 8As shown, in one embodiment of this application, the fastener 3 is a snap ring structure. The snap ring structure includes a fixing ring 31 fixed to the cover 2 and a hook 32 formed on the fixing ring 31. The hook 32 extends downward and cooperates with the holding part 4 to lock it in place. The hook 32 is hooked on the holding part 4 to lock the cover 2 in place. Specifically, the hook 32 is a U-shaped bent structure, and the holding part 4 passes through the U-shaped bent structure to lock the cover 2 onto the housing 1.

[0040] To facilitate the rotatable connection between the housing 1 and the cover 2, the cover 2 is fixed with a hinge 33, which is arranged opposite to the lug 32. The outer peripheral wall of the top of the housing 1 has a protrusion 34, and the hinge 33 is rotatably connected to the protrusion 34. This design is simple and easy to assemble, ensuring that the cover 2 and the housing 1 are coaxially aligned. When the cover 2 is closed, one side of the cover 2 is hinged and fixed to the protrusion 34 through the hinge 33, and the other side of the cover 2 is engaged with the retaining part 4 through the lug 32. This ensures that the cover 2 is firmly attached to the housing 1, guaranteeing the sealing of the injection hole 11 and preventing leakage.

[0041] Preferably, the hinge portion 33 is integrally connected to the fixed ring 31 on the side opposite to the lug 32. Both the lug 32 and the hinge portion 33 are approximately perpendicular to the plane of the fixed ring 31. The fixed ring 31, the lug 32, and the hinge portion 33 are integrally connected to form the retaining spring structure. The retaining spring structure is formed by bending metal wire. The broken end of the metal wire is located in the middle of the hinge portion 33 and is rotatably disposed within the protrusion 34. The protrusion 34 has the function of constraining the broken end of the metal wire, preventing the broken end of the metal wire from spreading out. In this way, the broken end of the metal wire does not need to be welded, which is convenient for manufacturing and assembly, and the production cost is low. The broken end of the metal wire is hidden and fixed within the protrusion 34, avoiding exposure, making the appearance simpler and more beautiful. In order to facilitate the stable installation of the fixing ring 31 on the cover 2, the cover 2 is provided with a fixing groove 20 around its perimeter that is adapted to the fixing ring 31. The fixing ring 31 is locked in the fixing groove 20. This can improve the fixing strength between the fixing ring 31 and the cover 2 and prevent the fixing ring 31 from detaching from the cover 2, causing the cover 2 to open accidentally and leak liquid.

[0042] like Figure 5 , Figure 8 and Figure 9As shown, preferably, the hinge portion 33 includes two connecting segments 331 and a hinge shaft 332. One end of the two oppositely arranged connecting segments 331 is fixed to the cover 2 (specifically, the two connecting segments 331 are integrally connected to the fixing ring 31, and then fixed to the cover 2 by the fixing ring 31). The other ends are connected to the hinge shaft 332 (i.e., formed by the broken end of a metal wire) with a break 330, forming two symmetrically arranged L-shaped structures. A shaft hole is opened on the protrusion 34, and the hinge shaft 332 is rotatably inserted into the shaft hole. The two connecting segments 331 are respectively located on both sides of the protrusion 34. In this embodiment, there are two shaft holes arranged axially at intervals, respectively located on both sides of the protrusion 34. It can be understood that the shaft holes can also be axially continuous as one. The hinge shaft 332 with a break 330 is easy to insert into the shaft hole from both ends through the break 330. The hinge part 33 is formed by two connecting sections 331 and the hinge shaft 332 with a break 330. In this way, the hinge shaft 332 for the cover 2 to rotate is fixedly connected to the fixing ring 31 through the two connecting sections 331. The rotation connection and locking of the cover 2 are integrated into the snap ring structure, which reduces the related parts of the rotation connection of the cover 2, reduces the manufacturing cost, and makes assembly more convenient. It has the advantages of simple structure, compactness and easy manufacturing.

[0043] It is understood that in other embodiments, the fastener 3 may omit the fixing ring 31, and the hanging ear 32 and hinge portion 33 may be fixed to the cover 2.

[0044] In other embodiments, the latching member 3 is not limited to the aforementioned snap ring structure. The latching member 3 can also be a lock integrally connected to the cover 2, the lock being U-shaped and having a locking hole. The retaining part 4 is engaged within the locking hole, thereby closing the cover 2. This lock is formed by a U-shaped tubular component enclosing the locking hole, but the lock is not limited to a U-shape; it can also be annular, trapezoidal, or square, etc. Furthermore, the latching member 3 can also be a block integrally connected to the cover 2 with a locking hole.

[0045] like Figure 6 and Figure 8As shown, in one embodiment of this application, the retaining part 4 is a movable button, which has a switchable retaining position and a disengaging position for closing and opening the cover 2 respectively. Preferably, the movable button includes a key body 41, an elastic element 42, and a limiting element 43. The outer peripheral wall of the top of the housing 1 (specifically the outer peripheral wall of the first end cover 13) is provided with a key groove 18 that matches the shape and size of the key body 41. The elastic element 42 is disposed in the key groove 18. One end of the key body 41 is disposed in the key groove 18 and abuts against the elastic element 42 to form an elastic abutting end. The other end of the key body 41 extends out of the housing 1 to form a pressing end for passing through the hanging ear 32. The limiting element 43 of the key body 41 is disposed at the top of the housing 1 to limit the reciprocating stroke of the key body 41, that is, the stroke between the retaining position and the disengaging position, to prevent the key body 41 from disengaging from the key groove 18. In this embodiment, the limiting member 43 is disposed on the top wall of the housing 1 (specifically, the end wall of the first end cover 13). A limiting groove 44 is provided on the key body 41 to slide and engage with the limiting member 43. The limiting member 43 can slide through the limiting groove 44 along its extension direction. The two end faces of the limiting groove 44 abut against the limiting member 43 to limit the travel of the key body 41. The pressing end of the key body 41 has an inclined surface to allow the lug 32 to slide smoothly downwards along the inclined surface and engage with the pressing end of the key body 41. In use, when the cover 2 is closed, the pressing end of the key body 41 engages with the lug 32, the elastic member 42 is in an extended state, and the limiting member 43 abuts against the left end face of the limiting groove 44 for limiting. At this time, the active button is in the engaged position. By pressing the key body 41, the engaged position is switched to the disengaged position. When the cover 2 needs to be opened to replenish e-liquid, the pressing end of the key body 41 is pressed, and the elastic element 42 is compressed under the pressing force. The key body 41 slides inward along the extension direction of the keyway 18. When the key body 41 slides to the right end face of the limiting element 43 and the limiting groove 44, the pressing end of the key body 41 disengages from the hanging ear 32, thereby allowing the cover 2 to be rotated open to replenish e-liquid. The movable button uses the key body 41, elastic element 42 and limiting element 43 in combination, which makes the structure simple and compact, and easy to implement the pressing action on small parts. During assembly, it is only necessary to open the keyway 18 on the peripheral wall of the first end cover 13, place the elastic element 42 and the key body 41 in the keyway 18 in sequence, and let the limiting element 43 pass through the top wall of the first end cover 13 and pass through the limiting groove 44 of the key body 41. This assembly is convenient, which helps to improve production efficiency and reduce production costs.

[0046] In this embodiment, the limiting member 43 is a pin, which has a simple structure, is easy to install, and facilitates sliding engagement with the limiting groove 44. In other embodiments, the limiting member 43 can also adopt other structural forms, such as providing a stepped limiting part on the key body 41 and a limiting protrusion at the outer end of the keyway 18, with the limiting protrusion cooperating with the stepped limiting part to achieve limiting. It is understood that the limiting member 43 can also adopt other structural forms, as long as it can limit the stroke of the key body 41, which will not be listed here. In this embodiment, the elastic member 42 is a spring, which provides the elastic force for the key body 41 to return to its original position. In addition, the elastic member 42 can also adopt other elastic structures such as a spring sheet or elastic colloid, which are not limited here.

[0047] like Figure 1 and Figure 8 As shown in the embodiment of this application, the atomizer also includes a base 7, which is connected to the second end cap 14. Specifically, the base 7 and the second end cap 14 are screwed together. A rotatable airflow regulating ring 8 is fitted around the outer periphery of the base 7, and the airflow regulating ring 8 is rotatably mounted on the outer periphery of the base 7 via a pressure cap 9. The airflow volume is adjusted by rotating the airflow regulating ring 8. A positive electrode 71 and a negative electrode 72 are mounted on the base 7 for electrical connection with the heating element of the atomizing core 6.

[0048] The atomizer provided in this application embodiment also includes a cover tube 61 disposed in the housing 1. The two ends of the cover tube 61 are respectively connected to the first end cap 13 and the second end cap 14. The atomizing core 6 is located inside the cover tube 61, and the cover tube 61 has a liquid inlet hole for the e-liquid to flow into the atomizing core 6.

[0049] Example 2

[0050] like Figure 10 As shown, this application provides an atomizer, including a housing 1 and a cover 2. The housing 1 has a liquid storage chamber 10 for storing e-liquid. The top of the housing 1 has an injection hole 11 communicating with the liquid storage chamber 10. The cover 2 is movably connected to the top of the housing 1 and can seal the injection hole 11 (same as above). Figure 7 The cover 2 is provided with a buckle 3 on its outer periphery, and the top outer periphery of the housing 1 is provided with a retaining part 4. The buckle 3 and the retaining part 4 cooperate to lock the cover 2 closed. The cover 2 can be opened by triggering the buckle 3 or the retaining part 4 to disengage them.

[0051] The atomizer provided in this application embodiment features a cover 2 movably connected to the housing 1, a latching member 3 on the cover 2, and a retaining part 4 on the outer peripheral wall of the top of the housing 1 that movably engages with the latching member 3. During use, the cover 2, under the engaging action of the latching member 3 and the retaining part 4, tightly seals the injection hole 11, preventing leakage. When it is necessary to add e-liquid to the storage chamber 10, simply triggering the latching member 3 or the retaining part 4 disengages them, opening the cover 2 and exposing the injection hole 11 for e-liquid injection. After e-liquid injection, simply closing the cover 2 causes the latching member 3 to engage with the retaining part 4, thus sealing the injection hole 11. This simple operation facilitates easy replenishment of e-liquid into the storage chamber 10 through the injection hole 11, improving the user experience. The atomizer with the above-mentioned structural design only needs to have a buckle 3 on the cover 2 and a retaining part 4 on the outer peripheral wall of the top of the shell 1. In this way, the structural design is reasonable, the assembly is simple, the production cost of the atomizer is reduced, and the production efficiency of the atomizer is improved.

[0052] In this embodiment, the retaining part 4 is a boss fixed to the outer peripheral wall of the top end of the housing 1. The boss cooperates with the fastener 3 to secure the cover 2. Preferably, the boss is integrally connected to the outer peripheral wall of the top end of the housing 1, which simplifies assembly and makes the structure more robust. Alternatively, the boss can be separately connected to the outer peripheral wall of the top end of the housing 1, specifically by means of screwing or snap-fit. Preferably, the boss has an inclined surface, so that the fastener 3 can smoothly slide down the inclined surface and be retained on the boss. The retaining part 4 adopts a fixed boss, which further simplifies the structure, reduces assembly steps, and lowers manufacturing costs compared to the movable button in embodiment one.

[0053] The remaining parts of the atomizer in this embodiment can adopt the corresponding structure in the atomizer embodiment, and will not be described in detail here.

The electronic cigarette equipped with the aforementioned atomizer allows for easy opening of the cover 2 and injection of e-liquid into the housing 1 through the injection hole 11, simplifying operation and improving the user experience.
