[0041] The adjustment valve 40 is slidably disposed on one side of the rear housing 20, and the adjustment valve 40 is provided with a plurality of adjustment air holes 410. Among them, when the adjustment valve 40 is in different positions, the plurality of adjustment air holes 410 and the plurality of rear ventilation holes 210 form air flow channels with different pore diameters.

[0042] Specifically, the regulating valve 40 has a regulating plate 41 and a pair of pushing portions 42. The regulating plate 41 is in an inverted U shape, forming a hollow portion 43. The outer shape of the hollow portion 43 corresponds to the outer shape of the puncturing member 24. The puncturing member 24 can penetrate through the hollow portion 43 and pierce into the fragrance packet 50. A row of regulating air holes 410 is formed on each side of the regulating plate 41. The pair of pushing portions 42 are oppositely connected to both sides of the regulating plate 41 and are respectively slidably disposed in a pair of sliding grooves 224 on the rear side wall 22. In this embodiment, there are five columns of regulating air holes 410 from top to bottom, having the same spacing. Each regulating air hole 410 is rectangular, but is not limited thereto.

[0043] The assembly and positioning mechanism of the rear housing 20 and the regulating valve 40 is described as follows. As Figure 1 and Figure 8 shown, the rear housing 20 has a pair of holding arms 23 and a positioning projection 232. The holding arms 23 are perpendicular to the rear wall plate 21 and are located inside the rear side wall 22. The positioning projection 232 is formed at the bottom end of the holding arms 23. Two positioning grooves 412 are formed on each side edge of the regulating plate 41 of the regulating valve 40. The holding arms 23 clamp the regulating plate 41. The positioning projection 232 can alternatively be located in one of the positioning grooves 412 to position the regulating valve 40 in the open state (as Figure 7 shown) or the closed state (as Figure 8 shown).

[0044] When a user uses the fragrance device, first combine the fragrance packet 50 with the adapter cassette 30 and insert the fragrance packet 50 from the rear of the adapter cassette 30. Then place the adapter cassette 30 and the fragrance packet 50 together into the space between the front housing 10 and the rear housing 20 from the top of the fragrance device. After completion, as Figure 4 shown.

[0045] As Figures 5 to 6 shown, respectively are cross-sectional views of the puncturing member of the fragrance device of the present utility model in the non-pressed state and the pressed state. The fragrance packet 50 has at least one accommodation shell 51, a rupturable film 54 and an elastic microporous film 55. A stepped portion 52 and a peripheral portion 53 are formed around the accommodation shell 51. The accommodation shell 51 contains a volatile liquid. The elastic microporous film 55 covers the peripheral portion 53 of the accommodation shell 51. The elastic microporous film 55 forms many breathable micropores. The material of the elastic microporous film 55 has elasticity and cannot be pierced by the puncturing member 24. The rupturable film 54 covers around the stepped portion 52 and is located inside the elastic microporous film 55. The material of the rupturable film 54 is air-impermeable, such as aluminum foil or air-impermeable kraft paper. In the unused state, the rupturable film 54 seals the fragrance packet 50.

[0046] As Figure 6As shown, after the fragrance packet 50 is installed in the adapter box 30, the user presses the pressing part 243 of the puncturing member 24 towards the fragrance packet 50, so that the puncturing plate 241 of the puncturing member 24 faces the fragrance packet 50. The puncturing plate 241 pushes the elastic microporous membrane 55 and abuts against the rupturable membrane 54. The elastic microporous membrane 55 is elastic and will not rupture during the pushing process. Then, the puncturing plate 241 punctures the rupturable membrane 54 of the fragrance packet 50 to form a puncture hole.

[0047] As Figure 7 and Figure 8 , they are respectively schematic diagrams of the rear housing and the regulating valve of the fragrance device of the present utility model in a permeable state and in a closed state. As Figure 7 shown, the regulating air hole 410 of the regulating valve 40 is aligned with the rear air permeable hole 210 of the rear housing 20 to provide an air flow channel with the largest aperture. As Figure 8 shown, the regulating valve 40 moves downward to the bottom, that is to say, the pushing part 42 slides to the bottom of the sliding groove 224. The regulating air hole 410 of the regulating valve 40 is completely staggered from the rear air permeable hole 210 of the rear housing 20, and they block each other to reduce the air flow channel. Thereby, the evaporation rate of the internal liquid of the fragrance packet 50 can be adjusted.

[0048] [Advantages of the Embodiment]

[0049] One of the advantages of the present utility model is that the fragrance device provided by the present utility model can activate the fragrance packet 50 through the puncturing member 24 and hold the fragrance packet 50 through the adapter box 30, reducing the situation where the user directly contacts the fragrance packet. In addition, the fragrance device of the present utility model can also adjust the evaporation rate of the internal liquid of the fragrance packet 50 through the regulating valve 40.
