Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette structure, specifically to an electronic cigarette air conditioning structure that reduces airflow noise and whistling. Background Technology

[0002] In existing air regulating ports, airflow enters the air regulating channel inside the bottom cover through the air regulating port. Since the air regulating channel inside the bottom cover is a pre-reserved ventilation space on the bottom cover without additional air regulating structure, the product generates a loud whistling and airflow noise during suction, affecting the consumer's suction sensory experience. The existing technical structure has the following defects:

[0003] 1. The air intake stroke is too short. During the airflow process through the air intake, the airflow presents a "slow-fast-slow" rhythm. After the airflow passes through the vent wall, it is easy for the air to swirl and rotate on the inner wall of the ventilation space of the bottom cover, resulting in a whistling sound. Secondly, the rotating air mass also rubs against the direct airflow output from the vent, which further amplifies the airflow sound, resulting in excessive noise and affecting the suction experience.

[0004] 2. Without the airflow shaping structure installed, as more and more air masses rotate in the ventilation space during the suction process, the ventilation space area continuously decreases, and the noise level increases.

[0005] Therefore, in the current e-cigarette air conditioning structure, the air conditioning holes, with their regular shape, will produce more or less whistling and airflow noise at different inhalation rates. This phenomenon will cause the inhalation process to be too loud, reducing the user experience. Utility Model Content

[0012] Furthermore, the switch structure includes a gas regulating switch and a gas regulating silicone fixedly connected to the gas regulating switch. The gas regulating silicone is disposed in the slide groove, and the gas regulating switch can drive the gas regulating silicone to slide in the slide groove, thereby realizing the movement of the gas regulating switch.

[0013] Furthermore, the gas regulating switch has two locking feet on its back, and the gas regulating silicone has locking holes that mate with the locking feet. The gas regulating switch and the gas regulating silicone are engaged by the locking feet and locking holes.

[0014] Furthermore, the airflow shaping structure is disposed at one end of the microphone silicone, the airflow shaping structure includes a first groove surface that mates with the microphone silicone, and the airflow channel is longitudinally disposed in the middle of the first groove surface.

[0015] Furthermore, the airflow channel is an open second groove, which cooperates with the sidewall of the microphone silicone to form a closed channel.

[0016] Furthermore, the height of the airflow channel is 3-4 mm.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by adding an airflow shaping structure made along the outline of the airflow hole around the airflow hole, this utility model optimizes the air intake structure, extends the air intake passage, avoids the generation of swirling air masses, and changes the problem of large whistling and airflow noise caused by the lack of an airflow shaping structure around the airflow hole in the past.

[0023] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0024] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1-4As shown in the preferred embodiment of this utility model, the electronic cigarette air conditioning structure for reducing airflow noise and whistling sounds includes a bottom cover 4 and an air conditioning hole 7 disposed on the bottom cover 4. The bottom surface of the bottom cover 4 is provided with a switch structure that can open or close the air conditioning hole. It also includes an airflow shaping structure 1 disposed inside the bottom cover 4. The airflow shaping structure 1 has an airflow channel 101 that penetrates the airflow shaping structure 1 and corresponds to the position of the air conditioning hole 7. The cross-section and size of the airflow channel 101 match the air conditioning hole. The air conditioning hole 7 and the air intake channel 101 form the air intake channel of the electronic cigarette.

[0027] This invention optimizes the air intake structure and extends the air intake passage by adding an airflow shaping structure 7 made along the outline of the air intake 7 around the air intake 7, thereby avoiding the generation of swirling air masses and changing the problem of large whistling and airflow noise caused by the lack of an airflow shaping structure around the air intake 7 in the past.

[0028] Preferably, the airflow shaping structure in this example is made of high-polymer sound-absorbing cotton, which has the advantages of fewer burrs and curling edges, higher cotton density, less susceptibility to deformation under stress, and easy assembly. In addition, the sound-absorbing cotton can absorb the vibration generated by air friction, further reducing airflow noise and whistling.

[0029] In this example, the height of the sound-absorbing cotton is preferably between 3.5 ± 0.5 mm. When the height of the sound-absorbing cotton is less than 3 mm, a slight whistling sound will occur during suction. When the height of the sound-absorbing cotton is greater than 4 mm, the airway will be extended too much and the cotton height will exceed the height of the bottom cover, which may easily lead to the risk of clogging.

[0030] In this example, the bottom cover also has a charging interface 8 near the switch structure, and a charging circuit board 3 electrically connected to the charging interface 8 is also provided inside the bottom cover 4. This is a conventional structure and will not be described in detail here.

[0031] In this example, a microphone silicone 2 is also provided inside the bottom cover 4. One end of the microphone silicone 2 has a protruding microphone silicone. In this example, the sound-absorbing cotton and the microphone silicone elastically surround the vent hole on the inner side of the bottom cover, improving the stability and sealing performance of the structure. Specifically, the microphone silicone 2 in this example has a sealing ear 203 corresponding to the position of the air regulating hole 7. The sealing ear 203 has a through hole in the middle that matches the air regulating hole. The sealing ear 203 is located between the air regulating hole 7 and the airflow shaping structure 4, and is used to seal the gap between the air regulating hole 7 and the outer periphery of the contact surface of the airflow channel 101.

[0032] Preferably, in this example, the airflow shaping structure 7 is disposed at one end of the microphone silicone 2. The airflow shaping structure 1 includes a first groove surface 102 that mates with the microphone silicone. The airflow channel 101 is an open second groove longitudinally disposed in the middle of the first groove surface 102. The second groove mates with the side wall of the microphone silicone 2 to form a closed channel. Through the elastic interference fit between the first groove surface 102 of the airflow shaping structure 7 and the side wall of the microphone silicone 2, the airflow shaping structure 7 can be quickly assembled and reliably connected to the bottom cover 4.

[0033] Of course, the airflow channel 101 in this example can also be processed into a through hole corresponding to the air regulating hole 7, and then the effect of this utility model can also be achieved by the airflow shaping structure 7 cooperating with the side wall of the microphone silicone 2.

[0034] like Figure 3 and Figure 4 As shown, the bottom surface of the bottom cover in this example is provided with a groove, the air regulating hole 7 and the switch structure are disposed in the groove, and the bottom cover is also provided with a mounting hole 401 for installing the switch structure. The switch structure can slide in the mounting hole 401, thereby opening or covering and closing the air regulating hole.

[0035] Preferably, in this example, the microphone silicone 2 is provided with a positioning groove 202 corresponding to the groove and a sliding groove 201 corresponding to the position of the mounting hole 401, which enables the microphone silicone 2 to be easily fixed in the bottom cover 4. The outer periphery of the sliding groove 201 is reliably sealed to the mounting hole 401. The switch structure in this example includes a gas regulating switch 6 and a gas regulating silicone 5 fixedly connected to the gas regulating switch 6. The gas regulating silicone 5 is disposed in the sliding groove 201. The back of the gas regulating switch 6 is provided with two locking feet 601. The gas regulating silicone 5 is provided with locking holes 501 that cooperate with the locking feet. The gas regulating switch 6 and the gas regulating silicone 5 are engaged by the locking feet 601 and the locking holes 501.

[0036] After the switch structure is installed, the gas regulating silicone 5 in this example overlaps with the slide groove 201 through the outer protrusion 502, thereby realizing the connection of the switch structure. The gas regulating switch 6 can drive the gas regulating silicone 5 to slide in the slide groove 201, thereby realizing the movement of the gas regulating switch.

[0037] In summary, this invention not only avoids the whistling problem caused by air swirling and rotation, but also addresses the issue that in existing technologies, the area of ​​the air intake hole decreases or increases as the airflow switch 6 is moved, causing the airflow noise and whistling sound to decrease or increase accordingly. This invention adds a sound-absorbing cotton around the airflow hole 7, extending the airflow channel, optimizing the airflow direction, and absorbing noise. This effectively reduces the whistling and airflow noise generated by air friction, solving the problem of excessive airflow noise and noise affecting the vaping experience in adjustable draw resistance electronic cigarettes.

[0038] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
