Description

Technical Field

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

[0002] The atomizer contains an aerosol generating matrix, which is heated and atomized to form an aerosol. This aerosol mixes with the air entering the atomizer and then flows out for the user to inhale.

[0003] The pre-stored atomizing matrix in atomizers has a limited capacity. Currently, disposable atomizers on the market are often discarded indiscriminately after use, leading to environmental pollution and resource waste. Even when some companies set up atomizer recycling systems, they can only recover some parts, which also results in resource waste. Refillable atomizers are currently the most resource-efficient option. However, when users refill atomizers themselves, the process is often too cumbersome and inconvenient. Furthermore, the position is not accurately controlled during adjustment, posing a risk of leakage. Utility Model Content

[0004] The purpose of this application is to provide an atomizer and an electronic atomizing device, which aims to solve the problems that the operation process of replenishing the atomizer with liquid in existing atomizers is often too cumbersome, the position is not accurately controlled during adjustment, and there is a risk of oil leakage.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide an atomizer, comprising: an atomizing shell having a liquid storage chamber for storing an aerosol matrix, the top surface of the atomizing shell having an injection port communicating with the liquid storage chamber; a nozzle assembly slidably disposed on the top surface of the atomizing shell; and a positioning structure including an elastic positioning member disposed on one of the bottom surface of the nozzle assembly or the top surface of the atomizing shell, and at least two positioning holes disposed on the other of the bottom surface of the nozzle assembly or the top surface of the atomizing shell; the nozzle assembly being movable relative to the atomizing shell between a first position and a second position through the cooperation of the positioning member and the positioning holes; in the first position, the nozzle assembly covers the injection port; in the second position, the injection port is exposed to the outside.

[0007] The beneficial effects of the atomizer of this application are as follows: by controlling the sliding of the mouthpiece assembly relative to the atomizing shell, the mouthpiece assembly can slide between a first position and a second position relative to the atomizing shell, allowing the atomizer to switch between a normal use state and a state requiring refilling, making it convenient for users to quickly operate the atomizer and refill; furthermore, by utilizing the positioning cooperation between the elastic positioning element and the positioning hole, the mouthpiece assembly can be precisely positioned; when the mouthpiece assembly is slid to make the elastic positioning element engage with the positioning hole, a crisp sound and tactile feedback will be emitted, making it easy for users to accurately judge the adjustment position and providing users with accurate sliding feedback judgment information.

[0008] In some embodiments, the bottom surface of the nozzle assembly is provided with the positioning hole and a transverse groove formed between two adjacent positioning holes, and the depth of the transverse groove is less than the depth of the positioning hole; the top surface of the atomizing shell is provided with the elastic positioning member, and the elastic positioning member is slidably fitted in the transverse groove.

[0009] By adopting the above technical solution, the transverse groove can guide the elastic positioning component to slide, allowing the elastic positioning component to slide smoothly between the positioning holes; and the elastic positioning component is in a compressed state in the transverse groove. Due to the height difference between the positioning hole and the transverse groove, when the elastic positioning component enters the positioning hole from the transverse groove, it will be elastically locked into the positioning hole, which will produce a clear collision sound, and at the same time, it will also be accompanied by vibration feedback to the thumb, improving the user experience.

[0010] In some embodiments, the elastic positioning element includes a spring bead, the spring bead including a bead holder and a bead elastically connected within the bead holder, the bead being elastically extendable and retractable relative to the bead holder to engage with the positioning hole.

[0011] By adopting the above technical solution, the glass beads are elastically engaged in the positioning hole to achieve precise positioning of the base relative to the atomizing shell during movement.

[0012] In some embodiments, the atomizer further includes a sealing element disposed on the top surface of the atomizing shell, the sealing element including a barrier portion covering the liquid inlet, the barrier portion having a liquid inlet structure.

[0013] By adopting the above technical solution, the barrier section always covers the injection port. During injection, the aerosol matrix is ​​injected into the injection port through the liquid inlet structure of the barrier section, effectively preventing leakage.

[0014] In some embodiments, an air outlet channel is formed inside the atomizing shell, and an air outlet is formed on the top surface of the atomizing shell; an air inlet is formed inside the nozzle assembly, and an air inlet is formed on the bottom surface of the nozzle assembly; a through hole is provided on the sealing member; in the first position, the air outlet channel, the through hole and the nozzle air inlet are interconnected.

[0015] By adopting the above technical solution, the atomizer can be used for normal inhalation in the first position; and the sealing component can also form an effective seal between the air outlet and the air inlet to prevent air leakage.

[0016] In some embodiments, the nozzle assembly includes a nozzle body and a base, the bottom of the nozzle body is provided with a mounting groove, and the base is embedded in the mounting groove; the bottom surface of the base is provided with the positioning hole and the transverse groove.

[0017] By adopting the above technical solution, the base can be pre-slidably engaged with the slide, and then the base can be assembled with the nozzle body, making the assembly process simple and easy to operate.

[0018] In some embodiments, the top surface of the atomizing shell is provided with a slide base, and the slide base is provided with a sliding part; the base is provided with a corresponding sliding engagement part, and the sliding part and the sliding engagement part are slidably engaged.

[0019] By adopting the above technical solution, the slide and the base are slidably engaged through the sliding part and the sliding mating part, so that the base slides smoothly relative to the atomizing shell.

[0020] In some embodiments, the sliding portion includes a protrusion formed on the slide base, and the sliding engagement portion includes a groove provided on the slide base. The protrusion slides into the groove and restricts the base from moving away from the atomizing shell in the vertical direction.

[0021] By adopting the above technical solution, the upward movement of the base is effectively restricted from detaching from the atomizing shell, and the structure is stable.

[0022] In some embodiments, the nozzle assembly is provided with an indicator portion, which is used to indicate the orientation of the nozzle assembly as it moves from the first position to the second position.

[0023] Secondly, this application also provides an electronic atomizing device, including a power supply assembly and an atomizer as described above; the power supply assembly is used to supply power to the atomizer. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0047] Electronic atomizing devices are used to heat the atomizing substrate to generate atomized gas. Some existing atomizers, in order to enrich the vaping experience, have multiple parallel chambers, each containing an atomizing coil. The atomized gas generated in each chamber mixes in the airflow channel before being inhaled by the user. However, the airflow channel is usually small, and the gas flow rate within the channel is fast, resulting in the atomized gas being inhaled before it is fully mixed, affecting the taste and user experience.

[0048] Based on this, in order to solve the above problems, this application designs an atomizer. By setting a mixing chamber between the cover plate and each liquid storage chamber, the atomized gas generated in each liquid storage chamber will be mixed in the mixing chamber and then discharged from the gas outlet. The mixing chamber has a large capacity space, which is conducive to the mixing of each atomized gas and makes the atomized gas more uniform. The fully mixed atomized gas flows out of the atomizing shell, effectively improving the taste.

[0049] This application provides an electronic atomizing device, which includes an atomizer 100 and a power supply component, the power supply component being used to supply power to the atomizer 100.

[0050] Understandably, the atomizer 100 stores an aerosol matrix, and the power supply component is used to supply power to the atomizer 100, so that the atomizer 100 is powered on to heat up and atomize the aerosol matrix to generate atomized gas that can be inhaled by the user.

[0051] refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the atomizer 100 includes an atomizing shell 1 having a liquid storage chamber 110 for storing an aerosol matrix, the top surface 11 of the atomizing shell 1 having an injection port 12 communicating with the liquid storage chamber 110; a nozzle assembly 2, the bottom surface 210 of the nozzle assembly 2 being slidably disposed on the top surface 11 of the atomizing shell 1; a positioning structure including an elastic positioning member 3 disposed on one of the bottom surface 210 of the nozzle assembly 2 or the top surface 11 of the atomizing shell 1, and at least two positioning holes 4 disposed on the other of the bottom surface 210 of the nozzle assembly 2 or the top surface 11 of the atomizing shell 1, the nozzle assembly 2 being movable relative to the atomizing shell 1 between a first position and a second position by positioning and engaging with the positioning holes 4 through the elastic positioning member 3; and a base 21 covering the injection port 12 in the first position and exposing the injection port 12 to the outside in the second position.

[0052] Specifically, refer to Figure 1 The nozzle assembly 2 can slide relative to the atomizing shell 1. In the first position, the nozzle assembly 2 covers the liquid inlet 12, and the atomizer 100 can be used for normal inhalation; Reference Figure 2The nozzle assembly 2 is slidably adjusted from the first position to the second position, exposing the liquid inlet 12 to the outside, facilitating the replenishment of the aerosol matrix into the liquid storage chamber 110 and replenishing the liquid in the atomizer 100. Furthermore, the elastic positioning element 3 and the positioning hole 4 are engaged to precisely adjust the nozzle assembly 2 between the first and second positions, allowing for accurate adjustment and judgment by the user.

[0053] Understandably, the nozzle assembly 2 is slidably positioned at the top of the atomizing shell 1. The position of the nozzle assembly 2 can be adjusted by controlling the overall sliding of the nozzle assembly 2 relative to the atomizing shell 1, thereby selectively covering or opening the liquid injection port 12, making adjustment convenient.

[0054] The elastic positioning element 3 can elastically expand and contract, that is, in the first position and the second position, the elastic positioning element 3 can automatically and accurately engage into the corresponding positioning hole 4 to achieve precise positioning.

[0055] The atomizer 100 of this application allows the mouthpiece assembly 2 to slide relative to the atomizing shell 1 between a first and a second position, enabling the atomizer 100 to switch between a normal use state and a state requiring refilling, facilitating quick refilling by the user. Furthermore, the mouthpiece assembly 2 can be precisely positioned using the positioning engagement between the elastic positioning member 3 and the positioning hole 4. When the mouthpiece assembly 2 slides to engage the elastic positioning member 3 with the positioning hole 4, a crisp sound and tactile feedback are emitted, allowing the user to accurately determine the adjustment position and improving the user experience.

[0056] refer to Figure 3 In some embodiments, the bottom surface 210 of the nozzle assembly 2 is provided with positioning holes 4 and transverse grooves 6 formed between two adjacent positioning holes 4, and the depth of the transverse grooves 6 is less than the depth of the positioning holes 4; the top surface 11 of the atomizing shell 1 is provided with an elastic positioning member 3, which is slidably fitted in the transverse grooves 6.

[0057] Specifically, the transverse groove 6 is connected between the two positioning holes 4. During the sliding process of the nozzle assembly 2 relative to the atomizing shell 1 between the first position and the second position, the transverse groove 6 can guide the sliding trajectory of the elastic positioning member 3, so that the elastic positioning member 3 can slide linearly between the two adjacent positioning holes 4, and the positioning adjustment is more accurate.

[0058] Understandably, the depth of the positioning hole 4 is greater than the depth of the transverse groove 6. The elastic positioning element 3 is in a compressed state within the transverse groove 6 and has a tendency to elastically elongate. Due to the height difference between the positioning hole 4 and the transverse groove 6, when the elastic positioning element 3 slides from the transverse groove 6 into the positioning hole 4, it will elastically engage in the positioning hole 4, producing a clear collision sound. At the same time, it will also be accompanied by vibration feedback to the thumb, giving the user accurate sliding feedback judgment information.

[0059] refer to Figure 3 In some embodiments, there are two elastic positioning elements 3 and four positioning holes 4; and the two elastic positioning elements 3 and the four positioning holes 4 are symmetrically arranged about the central axis of the atomizing shell 1. Then, one elastic positioning element 3 cooperates with two positioning holes 4, and through the cooperation of the elastic positioning elements 3 on both sides with the positioning holes 4, the sliding structure of the nozzle assembly 2 is made more stable and does not jam.

[0060] refer to Figure 3 and Figure 7 In some embodiments, the elastic positioning element 3 includes a spring glass bead, which includes a glass bead seat 310 and a glass bead 320 elastically connected within the glass bead seat 310. The glass bead 320 can elastically extend and retract relative to the glass bead seat 310 to be engaged in the positioning hole 4.

[0061] Specifically, the glass bead 320 can engage with the positioning hole 4 to ensure accurate positioning of the base in the first and second positions.

[0062] In some embodiments, the glass bead 320 is a sphere. During the sliding process of the glass bead 320 along the transverse groove 6, the glass bead 320 rolls to effectively reduce sliding friction, thereby making the sliding of the nozzle assembly 2 smoother.

[0063] refer to Figure 2 and Figure 7 In some embodiments, the atomizer 100 further includes a sealing member 7 disposed on the top surface 11 of the atomizing shell 1. The sealing member 7 includes a blocking portion 71 covering the liquid injection port 12, and the blocking portion 71 is provided with a liquid inlet structure 8.

[0064] Specifically, the barrier 71 covers the injection port 12. When the nozzle assembly 2 is in the second position, the barrier 71 can effectively prevent the aerosol matrix in the atomizing shell 1 from spilling out of the injection port 12. During injection, the aerosol matrix is ​​injected into the injection port 12 through the liquid inlet structure 8 of the barrier 71, making the injection more reliable and preventing leakage.

[0065] For example, the liquid inlet structure 8 can be a liquid injection gap and a liquid injection hole provided on the barrier part 71. Understandably, the seal 7 is made of a flexible material, that is, the liquid injection gap and the liquid injection hole on the barrier part 71 can be flexibly deformed to facilitate liquid injection.

[0066] refer to Figure 1 and Figure 6 In some embodiments, an air outlet channel 5 is formed inside the atomizing shell 1, and an air outlet is formed on the top surface 11 of the atomizing shell 1; a mouthpiece air passage 201 is formed inside the mouthpiece assembly 2, and an air inlet is formed on the bottom surface 210 of the mouthpiece assembly 2; a through hole 10 is provided on the sealing member 7; in the first position, the air outlet channel 5, the through hole 10 and the mouthpiece air passage 201 are connected to each other.

[0067] refer to Figure 6 In the first position, the nozzle assembly 2 covers the liquid inlet 12, effectively preventing leakage. The central axis of the air outlet channel 5 coincides with the central axis of the nozzle air passage 201, that is, the atomized gas generated in the atomizing shell 1 can flow through the air outlet channel 5, the through hole 10 and the nozzle air passage 201 for the user to inhale.

[0068] Furthermore, the seal 7 can effectively seal both the air outlet and the liquid inlet 12, preventing leakage of liquid and air and improving the stability of the atomizer 100.

[0069] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the suction nozzle assembly 2 includes a suction nozzle body 22 and a base 21. The suction nozzle body 22 is provided with a mounting groove 13, and the base 21 is embedded in the mounting groove 13. The bottom surface of the base 21 is provided with a positioning hole 4 and the transverse groove 6.

[0070] Specifically, the nozzle body 22 and the base 21 are separate structures, and they move synchronously in the horizontal direction after assembly. During the assembly process, the base 21 can be pre-slidably engaged with the atomizing shell 1, and then the base 21 is assembled with the nozzle body 22. The assembly steps are simple and easy to operate. In the first position, the base 21 covers the liquid injection port 12; in the second position, the base 21 slides relative to the atomizing shell 1. In this position, the air outlet channel 5 is offset from the nozzle air channel 201, and the liquid injection port 12 is exposed to the outside, so that the aerosol matrix can be replenished into the liquid storage chamber 110 through the liquid injection port 12.

[0071] refer to Figures 3 to 6 In some embodiments, the top surface of the atomizing shell 1 is also provided with a slide 9, and the slide 9 is provided with a sliding part 91; the base 21 is provided with a corresponding sliding engagement part 220, and the sliding part 91 and the sliding engagement part 220 are slidably engaged.

[0072] Specifically, the slide base 9 and the base 21 are slidably engaged through the sliding part 91 and the sliding engagement part 220, so that the base 21 slides smoothly relative to the atomizing shell 1, and can be manually adjusted by the user.

[0073] The sliding part 91 and the sliding mating part 220 can adopt sliding mating methods such as slider and groove mating, slide rail and slide path mating, rolling element and guide groove mating.

[0074] refer to Figure 3 In some embodiments, the sliding part 91 includes a protrusion formed on the slide base 9, and the sliding engagement part 220 includes a groove provided on the slide base. The protrusion slides into the groove and restricts the base 21 from moving away from the atomizing shell 1 in the vertical direction.

[0075] It can be understood that the base 21 and the atomizing shell 1 are slidably engaged through the convex strip and the sliding groove. After the convex strip is slidably engaged on the sliding groove, it effectively restricts the base 21 from moving upward and detaching from the atomizing shell 1, and the structure is stable.

[0076] refer to Figure 1 and Figure 2 In some embodiments, the nozzle assembly 2 is provided with an indicator 23, which is used to indicate the orientation of the nozzle assembly 2 as it moves from the first position to the second position.

[0077] For example, the marking part 23 can be in the shape of an arrow. The direction of the suction nozzle assembly 2 moving from the second position to the second position can be accurately determined by the marking part 23, which is conducive to quick adjustment operation.

[0078] The application does not specify the model of the electronic atomizing device, that is, the shape of the electronic atomizing device can be flask-shaped, rectangular, cylindrical, etc.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
