Description

TECHNICAL FIELD

[0001] The utility model belongs to stationery product technical field, concretely relates to a pen, especially a pen with fragrance. BACKGROUND

[0002] The pen with fragrance is a special type of pen, which integrates the element of fragrance in design, so that various different fragrances can be emitted during use. This kind of pen is usually used to increase the pleasure of writing or to eliminate the fatigue during writing. In the market, the pen with fragrance is loved by many consumers, especially students and young people. The pen with fragrance is various in types and different in fragrance, which can meet the individualized needs of different consumers. They may be characterized by natural fragrances such as flower fragrance, fruit fragrance and grass fragrance, or have other unique fragrances. In addition to adding fragrance, some pens with fragrance also have specific functions. For example, some fragrance pens can repel mosquitoes and inhibit bacteria, which are suitable for use in outdoor or environments with more mosquitoes; some fragrance pens can promote sleep, which are suitable for use before sleep to relax the mood.

[0003] These fragrances are usually achieved by adding spices in the pen barrel, pen grip or ink, etc. For example, the Chinese patent with publication (announcement) number CN202826848U discloses a pen with refreshing function, which comprises a pen and a pen cover. The middle part of the pen cover is provided with a partition plate. A space for storing fragrance water is formed in the pen cover above the partition plate. A cotton ball is arranged in the space for storing fragrance water. A fragrance water dropping inlet and a fragrance water volatilization outlet are arranged on the upper side of the pen cover. A lid is arranged on the fragrance water dropping inlet. The pen is provided with a space for storing fragrance water, which can volatilize the fragrance of the fragrance water to play a refreshing role and help students concentrate on learning. For example, the Chinese patent with publication (announcement) number CN202826848U discloses a novel spice pen, which comprises a body. The body comprises a pen core, a pen tip sleeve and a pen body. The pen tip sleeve is threadedly connected with the bottom of the pen body. The pen tip sleeve and the pen body are sleeved on the pen core. The novel spice pen further comprises a spice bin, a spice rod, a pen holder and a pen cap. The pen cap is a hollow cavity, which is arranged on the top of the pen body and is threadedly connected with the pen body. A plurality of volatilization holes are formed in the surface of the pen cap and are symmetrically arranged on the left and right sides. The spice bin is also a hollow cavity, which is arranged in the interior of the pen cap. A plurality of volatilization windows are symmetrically formed in the surface of the spice bin. The volatilization windows in the spice bin are overlapped with the volatilization holes in the pen cap by rotating the pen holder, so that the volatilization is maximized. Alternatively, only half or less of the volatilization windows are overlapped with the volatilization holes in the case of heavy fragrance, so that the volatilization is reduced. When the volatilization is not needed, the pen holder is rotated to make the volatilization windows and the volatilization holes completely not overlapped, so that the volatilization of the fragrance is minimized. Although the existing pen with fragrance realizes the functions of volatilizing and diffusing fragrance, it still has two main defects:

[0004] Firstly, during the diffusion of fragrance, the fragrance liquid is prone to leakage due to the overturning of the pen when the pen barrel is placed horizontally, inverted or in other states.

[0005] Second, the fragrance time is short, the fragrance is not uniform, especially in the beginning, the fragrance is strong and pungent, and in the later period, the fragrance is very weak and almost not noticeable.

[0054] As shown in FIG. 1, a pen with fragrance comprises: Figures 1-8 a lower pen barrel 3, in which a writing lead 9 is arranged;

[0055]

[0056] ​The upper pen barrel 2 is connected with the lower pen barrel 3, the inside of the upper pen barrel 2 is hollow and forms a containing cavity, a first liquid absorption fragrance diffusion core 4 and a second liquid absorption fragrance diffusion core 5 are arranged in the containing cavity, a second fragrance diffusion hole 204 is arranged on the upper pen barrel 2, the first liquid absorption fragrance diffusion core 4 is located on the side close to the second fragrance diffusion hole 204, and the second liquid absorption fragrance diffusion core 5 is located on the side away from the second fragrance diffusion hole 204; when assembled, the adsorption rate of the fragrance liquid in the first liquid absorption fragrance diffusion core 4 is less than the adsorption rate of the fragrance liquid in the second liquid absorption fragrance diffusion core 5.

[0057] The upper cover 1 is rotatably covered on the upper end of the upper pen barrel 2, and a first fragrance diffusion hole 101 is arranged on the upper cover 1.

[0058] When fragrance diffusion is needed, the upper cover 1 is rotated so that the first fragrance diffusion hole 101 coincides with the second fragrance diffusion hole 204, at this time, the fragrance liquid in the first liquid absorption fragrance diffusion core 4 and the second liquid absorption fragrance diffusion core 5 can communicate with the external atmosphere through the second fragrance diffusion hole 204 and the first fragrance diffusion hole 101 and diffuse outward.

[0059] When fragrance diffusion is not needed, the upper cover 1 is rotated so that the first fragrance diffusion hole 101 is staggered with the second fragrance diffusion hole 204, that is, completely does not coincide, at this time, the fragrance liquid in the first liquid absorption fragrance diffusion core 4 and the second liquid absorption fragrance diffusion core 5 is closed in the upper pen barrel 2 and cannot communicate with the external atmosphere and stop diffusing outward.

[0060] As some examples of the utility model, the first liquid absorption fragrance diffusion core 4 is in a ring structure, the second liquid absorption fragrance diffusion core 5 is in a columnar structure, the first liquid absorption fragrance diffusion core 4 is arranged around the outside of the second liquid absorption fragrance diffusion core 5, and the second fragrance diffusion hole 204 is arranged on the side wall of the upper pen barrel 2, at this time, because the adsorption rate of the fragrance liquid in the first liquid absorption fragrance diffusion core 4 is less than the adsorption rate of the fragrance liquid in the second liquid absorption fragrance diffusion core 5, in use, the fragrance liquid in the first liquid absorption fragrance diffusion core 4 does not reach the saturation state and is not easy to leak, and the fragrance liquid in the second liquid absorption fragrance diffusion core 5 needs to diffuse into the first liquid absorption fragrance diffusion core 4 first and then diffuse to the outside through the second fragrance diffusion hole 204 and the first fragrance diffusion hole 101. In this way, the first liquid absorption fragrance diffusion core 4 can simultaneously play the roles of fragrance diffusion and absorption of the outflow fragrance liquid in the second liquid absorption fragrance diffusion core 5, the structure of the double-stage liquid absorption fragrance diffusion core can prolong the fragrance diffusion time, make the fragrance diffusion concentration relatively stable, and also prevent the fragrance liquid from leaking.

In this way, the total amount of the fragrance liquid stored in the liquid absorption fragrance diffusion core can be increased, the leakage can be prevented at the same time, and the fragrance diffusion time can be prolonged.

[0063] As some examples of the utility model, during assembly, the first liquid absorption fragrance diffusion core 4 can not adsorb or adsorb a small amount of fragrance liquid, such as the adsorption amount of the fragrance liquid in the first liquid absorption fragrance diffusion core 4 ≤0.5*the saturated adsorption amount of the first liquid absorption fragrance diffusion core 4, wherein the adsorption amount of the fragrance liquid=(the weight of the liquid absorption fragrance diffusion core after absorbing liquid-the weight of the liquid absorption fragrance diffusion core before absorbing liquid) / the weight of the liquid absorption fragrance diffusion core before absorbing liquid.
