Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an atomizer nozzle. Background Art

[0002] Electronic cigarettes are electronic products that use atomization technology to convert liquid into smoke and use it to replace cigarettes. At present, electronic cigarettes consist of two parts: electronic cigarette devices and smoke oil. Among them, smoke oil generally includes glycerin, propylene glycol, nicotine, sweeteners, cooling agents, acidifiers, edible flavors and other additives. Among the main components of smoke oil, glycerin is the main smoke-generating agent, that is, it produces smoke; propylene glycol is the main solvent, which is used to dissolve nicotine, sweeteners, cooling agents, acidifiers, edible flavors and other additives; nicotine is a substance that refreshes consumers; sweeteners are used to produce sweetness; cooling agents are used to produce a cool feeling; acidifiers are used to produce a sour feeling; and edible flavors are used to produce various flavors or aromas. Most of the existing electronic cigarettes place smoke oil mixed with other additives such as flavors in an atomizer for heating and atomization, and additives such as flavors are easily decomposed by heat to produce harmful substances, which brings certain health risks to consumers.

[0003] To solve the above problems, the industry has proposed a solution to use a smoke oil without flavoring, and flavors and other additives are supplied through a mouthpiece. For example, the Chinese utility model patent with the authorization announcement number CN211721891U discloses an electronic atomization cigarette mouthpiece, which includes a mouthpiece cover that can be nested on the mouthpiece of the electronic cigarette and is in a sleeve-shaped shape. A composite carrier for acting as a filter is provided in the mouthpiece cover, and a number of bursting beads are filled in the composite carrier. An air port is provided on the mouthpiece cover, and the air port, the composite carrier and the mouthpiece of the electronic cigarette cooperate to form an air path. The edible flavors and nicotine in the original electronic cigarette are made into bursting beads and placed in the oil-absorbing cotton in the mouthpiece cover, and are used in the mouthpiece of the electronic atomization cigarette, thereby avoiding the edible flavors and nicotine in the electronic cigarette from being heated together like the traditional structure. However, in actual use, we found that since the structure needs to break the bursting beads filled in the composite carrier, the dispersion of the flavor fluctuates greatly from breaking the bursting beads to the end of electronic cigarette smoking, which affects the taste absorbed by consumers. Summary of the invention

[0004] The main purpose of the utility model is to solve the technical problems that the dispersion fluctuation of the flavor of the existing electronic cigarette mouthpiece is large, which affects the taste absorbed by consumers, and the flavors and other additives are stored in the popping beads, so that consumers can only choose the corresponding taste and cannot mix it by themselves.

[0005] To achieve the above object, the present utility model first proposes an atomizer nozzle, which includes a housing. A receiving cavity and an air flow channel are provided inside the housing. The air flow channel communicates from the bottom of the housing to the top of the housing. Diffusion through holes are provided on the side wall of the air flow channel, and the air flow channel communicates with the receiving cavity through the diffusion through holes. A suction part is provided at the top of the housing, and an atomizer connection part is provided at the bottom of the housing. The air flow channel communicates from the suction part to the atomizer connection part.

[0006] Optionally, an annular inward protrusion is provided on the inner wall of the air flow channel, and the diffusion through hole communicates from the top of the annular inward protrusion to the receiving cavity.

[0007] Optionally, the cross section of the annular inward protrusion is an arc-shaped ridge structure.

[0008] Optionally, the number of diffusion through holes in the air flow channel is several, and the number of annular inward protrusions on the inner wall of the air flow channel is several. The diffusion through holes are radially symmetrically distributed on the annular inward protrusions along the axial direction of the air flow channel.

[0009] Optionally, the housing includes an upper cover and a base that are connected by covering each other. The upper cover is covered and connected to the base by threads or buckles.

[0010] Optionally, a sealing gasket is provided at the covering connection part of the upper cover and the base.

[0011] Optionally, the air flow channel is composed of several branch air flow channels, and diffusion through holes are provided on the side walls of the branch air flow channels.

[0012] Optionally, the receiving cavity is divided into several unit cavities by a partition, and the unit cavities communicate with the air flow channel through the diffusion through holes on the side wall of the air flow channel.

[0013] Optionally, a feeding through hole is provided in the upper part of the housing, and a hole cover is covered and connected to the feeding through hole.

[0014] Optionally, the atomizer connection part is a tubular structure in which the air flow channel extends downward.

[0015] The beneficial effects of the present utility model are:

[0016] (1)The atomizer nozzle of the present utility model can be filled with fragrance filler (the fragrance filler is fragrance liquid or paste, etc.) in the accommodating cavity, and is connected to the atomizer nozzle through the atomizer connecting part. When the electronic cigarette is turned on, the atomizer of the electronic cigarette works to generate atomized smoke. The smoker sucks through the sucking part of the nozzle, and the negative pressure brought by the sucking is transmitted to the air passage of the electronic cigarette atomizer through the air flow channel. The negative pressure brings out the atomized smoke of the atomizer to form a smoke flow. The smoke flow enters the smoker's mouth through the air flow channel. During the process of the smoke flow passing through the air flow channel, the fragrance filler in the accommodating cavity escapes fragrance gas. The fragrance gas escapes to the air flow channel through the escape holes, mixes with the atomized smoke and enters the smoker's mouth. Thus, the atomized smoke sucked by the smoker is the target taste smoke. Since the atomizer nozzle of this embodiment provides fragrance gas to the air flow channel through the escape through holes communicating with the accommodating cavity, the fluctuation of the fragrance content during the sucking process is small (no taste attenuation). Therefore, it can effectively solve the technical problem in the prior art that from the breaking of the popping bead to the end of the electronic cigarette smoking, the escape of the fragrance fluctuates greatly, affecting the taste absorbed by the consumer.

[0017] (2)The inner diameter of the air flow channel is narrowed by the annular inward protrusion, so that the Venturi effect is generated when the smoke flow passes through the annular inward protrusion during the sucking process, thereby increasing the negative pressure of the escape through holes and increasing the rate of the fragrance gas escaping from the escape through holes.

[0018] (3)The escape through holes of the atomizer nozzle in another embodiment of the present utility model are evenly distributed in the circumferential direction of the annular inward protrusion and form an escape unit. Usually, 1 escape unit is provided on the inner wall of the air flow channel. In the case of a particularly large fragrance content (such as a strong mint flavor), multiple escape units are provided on the inner wall of the air flow channel. Description of the Drawings

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0033] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, for the terms "and / or" or "and / or" that appear throughout the text, their meanings include three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the premise that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] Figures 1 - 11 This is one type of atomizer mouthpiece of the present utility model, which includes a housing 01. An accommodation cavity 02 and an air flow channel 05 are provided inside the housing 01. The air flow channel 05 communicates from the bottom of the housing 01 to the top of the housing. A diffusion through-hole 051 is provided on the side wall of the air flow channel 05. The air flow channel 05 communicates with the accommodation cavity 02 through the diffusion through-hole 051. A suction part 011 is provided at the top of the housing 01, and an atomizer connection part 012 is provided at the bottom of the housing 01. The air flow channel 05 is communicated from the suction part 011 to the atomizer connection part 012. During use, a fragrance filler (the fragrance filler is a fragrance liquid or paste, etc.) is filled in the accommodation cavity. It is connected to the mouthpiece of the atomizer through the atomizer connection part. When the electronic cigarette is turned on, the atomizer of the electronic cigarette works to generate atomized smoke. The smoker sucks through the suction part of the mouthpiece. The negative pressure brought by the suction is transmitted to the air passage of the electronic cigarette atomizer through the air flow channel. The negative pressure brings out the atomized smoke of the atomizer to form a smoke flow. The smoke flow enters the smoker's mouth through the air flow channel. During the process of the smoke flow passing through the air flow channel, the fragrance filler in the accommodation cavity dissipates fragrance gas. The fragrance gas escapes into the air flow channel through the diffusion holes and mixes with the atomized smoke and enters the smoker's mouth. Thus, the atomized smoke inhaled by the smoker is the target taste smoke. Since the atomizer mouthpiece of this embodiment provides fragrance gas to the air flow channel through the diffusion through-holes communicating with the accommodation cavity, the fluctuation of the fragrance content during suction is small, and the fragrance filler filled in the accommodation cavity can be selected according to the smoker's own preference. Therefore, it can effectively solve the technical problem in the prior art that from breaking the popping bead to the end of smoking the electronic cigarette, the dissipation of the fragrance fluctuates greatly, affecting the taste absorbed by the consumer.

[0036] Specifically, in order to increase the dissipation rate of the fragrance gas through the diffusion through-holes, an annular inward protrusion 052 is provided on the inner wall of the air flow channel 05. The diffusion through-hole 051 communicates from the top of the annular inward protrusion 052 to the accommodation cavity 02. This annular inward protrusion narrows the diameter of the air flow channel inward, causing the Venturi effect to occur when the smoke flow passes through the annular inward protrusion during suction, thereby increasing the negative pressure of the diffusion through-holes and increasing the dissipation rate of the fragrance gas through the diffusion through-holes.

[0037] Specifically, the cross-section of the annular inward protrusion 052 is an arc-shaped ridge structure, and the inner surface of the arc-shaped ridge structure is an arc surface, with smoother air flow changes.

[0038] In one embodiment, as Figures 4 - 7 shown, the number of the dissipation through holes 051 of the air flow channel 05 is several, the number of the annular inward protrusions 052 on the inner wall of the air flow channel 05 is several, and the dissipation through holes 051 are radially symmetrically distributed on the annular inward protrusions 052 along the axial direction of the air flow channel. It can be understood that the dissipation through holes are evenly distributed in the circumferential direction of the annular inward protrusion and form a dissipation unit. Usually, one dissipation unit is arranged on the inner wall of the air flow channel. In the case of requiring a particularly high flavor content (such as a strong mint flavor), multiple dissipation units are arranged on the inner wall of the air flow channel.

[0039] For the convenience of filling the flavor filler in the accommodation cavity, in one embodiment, the housing 01 includes an upper cover 013 and a base 014 that are hermetically connected. The upper cover is hermetically connected to the base 014 through a thread 015 or a snap 016. Through this structure, it is also convenient for the smoker to independently prepare different flavors of flavors.

[0040] To prevent the flavor from escaping through the gap between the upper cover and the base, a sealing gasket 017 is provided at the hermetically connected joint of the upper cover 013 and the base 014. Specifically, the sealing gasket 017 is provided at the inner wall of the top of the upper cover 013 or the inner side wall of the lower edge of the upper cover 013.

[0041] Specifically, the upper cover 013 further includes a suction part through hole 020, and a sealing gasket 017' is provided on the inner wall of the suction part through hole 020 for the hermetic connection between the upper cover and the suction part.

[0042] As another implementation manner to increase the flavor gas content during the suction process of the atomizer nozzle (see Figures 8 - 10 ), the air flow channel 05 is composed of several branch air flow channels 053, and the side walls of the branch air flow channels 053 are provided with dissipation through holes 051. That is, the air flow channel 05 branches downward from the suction part into branch air flow channels and then converges at the atomizer connection part. By dissipating and mixing the flavor gas through multiple branch air flow channels, the flavor gas content during the suction process of the atomizer nozzle can be greatly increased.

[0043] In another embodiment, the accommodation cavity 02 is divided into several unit cavities 022 by a partition 021, and the unit cavities 022 are communicated with the air flow channel 05 through the dissipation through holes 051 on the side wall of the air flow channel 05. Different flavor fillers can be filled in different unit cavities through several unit cavities to meet different requirements of the smoker for the taste.

[0044] To further facilitate the addition of fragrance filler into the accommodation cavity, a feeding through-hole 018 is provided at the upper part of the housing 01, and a hole cover 019 is connected and covered on the feeding through-hole 018. When it is necessary to add fragrance filler into the accommodation cavity, the hole cover is pulled out, and the fragrance filler is added into the accommodation cavity through the feeding through-hole. After the addition, the hole is covered to prevent the fragrance gas from escaping through the feeding through-hole.

[0045] To facilitate the connection between the atomizer nozzle and the atomizer, the atomizer connection part 012 is a tubular structure extending downward from the air flow channel 05.

[0046] As described in the above multiple embodiments, the housing can be in various shapes such as cylindrical or rectangular, and whether to set the split structure of the upper cover and the base can be combined according to actual needs. These combination schemes also fall within the protection scope of the present invention, and these combination methods will not be elaborated one by one.

[0047] As another embodiment, as Figure 11 shown, the housing 01 and the air flow channel 05 are independent components, wherein the air flow channel 05 is an extended tubular structure of the suction part 011, and it is fixedly connected to the housing through fixing methods such as adhesion. The escape through-hole 051 passes through the side walls of the air flow channel 05 and the housing 01 and communicates with the accommodation cavity 02. This embodiment is a configuration of a single-sided accommodation cavity.

[0048] It is worth noting that the atomizer applying the atomizer nozzle structure of the above various embodiments is also within the protection scope of the present invention.

[0049] The above are only optional embodiments of the present invention, and thus do not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
