Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarettes, and in particular relates to an electronic cigarette with a hidden air regulating valve. Background Art

[0002] In the current e-cigarette market, end customers are very picky about the taste of e-cigarettes, and they are not the same, especially for the inhalation resistance (suction resistance). There are different methods such as mouth inhalation, lung inhalation, and half-lung inhalation. Therefore, in order to meet the needs of different customers, e-cigarettes are often designed with air regulating valves, and air inlet holes of different diameters are opened on the air regulating valves. The aperture of the air inlet hole is changed by sliding the air regulating valve to adjust the inhalation resistance.

[0003] The mainstream electronic cigarette products on the market that can adjust the airflow often have a flat or relatively flat curved surface at the air inlet position, and then design a piece of silicone inside. Holes are opened in the silicone corresponding to the air hole position of the air regulating valve. The sealing is achieved through the interference fit between the silicone and the plane of the air regulating valve, and air is taken in through the two air holes, thereby achieving the adjustment of the inhalation resistance.

[0004] The iteration speed of products in the e-cigarette market is very fast. In order to attract customers’ attention, industrial designers will also design product shapes with large surface transitions and require the installation of air regulating valves on them. However, technical personnel are often conservative and are forced to abandon this appearance plan after receiving feedback that it is technically difficult to achieve. Utility Model Content

Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model. Components of the embodiments of the present utility model described and shown in the drawings herein can generally be arranged and designed in a variety of different configurations.

[0023] In the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] As Figures 1 to 9 shown, an electronic cigarette with a hidden air regulating valve in this embodiment includes a housing 1. Inside the housing 1, there is a lower silica gel 2 and a sealing silica gel 3. A cavity 4 is formed between the lower silica gel 2 and the sealing silica gel 3. The cavity 4 is connected to an atomization airway 5. A microphone 6 is provided on the sealing silica gel 3, and the microphone 6 is connected to the cavity 4; a large through hole 18 and a small through hole 19 are provided on the sealing silica gel 3; an air regulating valve 7 is provided below the sealing silica gel 3. The air regulating valve 7 is provided with a large air inlet hole 8 and a small air inlet hole 9. A dial block 10 at the bottom of the air regulating valve 7 is located in an adjustment hole 11 opened at the bottom of the housing 1. The air regulating valve 7 is also provided with a large indicating hole 12 and a small indicating hole 13, and the large indicating hole 12 and the small indicating hole 13 are located on both sides of the dial block 10.

[0026] An electronic cigarette also includes a PCBA board, a battery cell, a heating wire, an oil storage cotton and other functional parts. When the user sucks from the mouthpiece, the air flow enters the cavity 4 through the large air inlet hole 8 or the small air inlet hole 9. When the air flow flows through the cavity to the bottom of the heating wire in the atomization airway 5, the microphone 6 will be triggered to start by negative pressure. At this time, the battery cell discharges, and the heating wire starts to work, atomizing the e-liquid in the oil storage cotton into smoke.

[0027] The air regulating valve 7 is provided with an arc-shaped convex rib 16, and the large indicating hole 12, the small indicating hole 13 and the equalizing block 10 are arranged on the arc-shaped convex rib 16; the arc-shaped convex rib 16 of the air regulating valve 7 is designed to be in imitation of the sliding surface of the curved surface. Since the sliding surface will be exposed outside, the large indicating hole 12 and the small indicating hole 13 are opened. These two holes are only for users to check the state of the air regulating valve. The large air inlet hole 8 or the small air inlet hole 9 is arranged on one side plane of the air regulating valve. The large air inlet hole 8 or the small air inlet hole 9 is hidden inside the housing 1 and is not exposed on the surface of the housing 1. It is in interference fit with the sealing silica gel 3 to play the roles of sealing and air regulation; a hollow groove 17 is arranged inside the arc-shaped convex rib 16. After the two sides of the air regulating valve 7 are squeezed, it can elastically deform towards the middle, which is convenient for assembly.

[0028] A first limiting plate 14 is arranged inside the housing 1. The two first limiting plates 14 are located above the air regulating valve 7 and are used to limit the air regulating valve 7 in the up and down directions. A second limiting plate 15 is arranged inside the housing 1. The two second limiting plates 15 are located on both sides of the arc-shaped convex rib 16 to limit the air regulating valve 7 in the front and back directions. The first limiting plate 14 and the second limiting plate 15 limit the degrees of freedom of the air regulating valve in the up and down directions and the front and back directions, ensuring that the air regulating valve can only slide left and right. During assembly, directly press the air regulating valve from above, and it can be snapped in by using the elastic deformation of the plastic. Then fix the sealing silica gel above, which is in interference fit with the plane of the air regulating valve, and large through holes 18 and small through holes 19 are respectively opened at the positions corresponding to the large air inlet hole 8 and the small air inlet hole 9 to facilitate the entry of air flow.

[0029] As Figures 4 - 6 shown, when the air regulating valve is adjusted to the large hole state, the gap between the left side of the air regulating valve and the inside of the housing is relatively large. Therefore, the left end of the air regulating valve needs to be extended for a section to prevent the internal structure from being exposed outside. Since the right side edge of the air regulating valve contacts the right side edge of the hole position of the outer shell, the air regulating valve cannot slide further. At this time, the large indicating hole 12 is exposed outside, and the large air inlet hole 8 corresponds to the large through hole 18.

[0030] As Figures 7 - 9 shown, when the air regulating valve is adjusted to the small hole state, there is no interference with the side edge of the curved surface. Since the left side edge of the air regulating valve contacts the left side edge of the hole position of the outer shell, the air regulating valve cannot slide further. At this time, the small indicating hole 13 is exposed outside, and the small air inlet hole 9 corresponds to the small through hole 19.

[0031] The present utility model is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they are all within the protection scope of the present utility model.
