Description

Technical Field

[0001] This utility model relates to the field of car air freshener technology, and in particular to a leak-proof structure for a car perfume container. Background Technology

[0002] Car air fresheners are fragrance products specifically designed for the interior environment of cars, primarily used to improve air quality, create a comfortable atmosphere, and help alleviate driving fatigue. Currently, car air fresheners on the market are mainly divided into three categories: first, vent air fresheners that clip onto the air conditioning vents; second, air freshener holders or bottles that are fixed to the center console or dashboard using adhesive; and third, hanging air fresheners that suspend from the rearview mirror. These products typically rely on absorbent cotton wicks and / or scented cotton pads to absorb the fragrance liquid, which is then directly exposed to the air for natural evaporation.

[0003] However, during vehicle operation, the vehicle is subject to frequent starts and stops, turns, and bumps, and the interior temperature fluctuates greatly (such as during high temperatures in summer). Existing air freshener containers generally have simple sealing structures and insufficient leak-proof performance, which makes it easy for the fragrance liquid to overflow, drip, or even splash from the cotton wick interface or bottle gaps. This may not only contaminate the interior surface but also pose safety hazards, affecting the driving experience and user satisfaction. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof structure for a car perfume container in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A leak-proof structure for a car perfume container includes a lower cover connected to the perfume container. The lower end of the inner wall of the lower cover is integrally formed with a funnel-shaped protrusion and a stepped tube. The funnel-shaped protrusion has multiple first leakage grooves around its central axis. The stepped tube has a second leakage groove between its inner and outer walls around its central axis. One end of the first leakage groove passes through the funnel-shaped protrusion's inclined surface, and the other end of the first leakage groove connects to the second leakage groove. An absorbent cotton core is inserted into the stepped tube, and a first fragrance-dispersing cotton pad is placed at the top of the stepped tube. An upper cover is threadedly connected to the lower cover. The upper cover has multiple odor dispersing openings, and a pressure ring that abuts against the first fragrance-dispersing cotton pad is fixedly connected to the bottom of the upper cover.

[0006] As a further description of the above technical solution: The pressure ring includes a connecting ring fixedly connected to the upper cover, and an inwardly opening V-shaped ring fixedly connected to the connecting ring.

[0007] As a further description of the above technical solution: The pressure ring also includes an annular boss that is fixedly connected to the outside of the V-shaped ring, and a second fragrance cotton pad is sleeved on the annular boss.

[0008] As a further description of the above technical solution: The bottom of the second leakage tank has a constricted opening structure.

[0009] As a further description of the above technical solution: The odor vent is a V-shaped opening facing the center of the top cover.

[0010] As a further description of the above technical solution: The stepped tube is fitted with a sealing ring that mates with the lower cap and the perfume container.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, when the vehicle is bumpy, the temperature rises and the fragrance evaporates too quickly or the cotton core is saturated, the excess fragrance may overflow from the first fragrance cotton pad and drip onto the surface of the funnel-shaped protrusion below. The overflowing liquid collects along the inclined surface of the funnel, flows into the second leakage channel through the first leakage channel, and finally slowly flows back into the perfume container through the constricted bottom end, realizing the automatic recovery of the overflowing fragrance and significantly reducing the risk of leakage.

[0012] 2. In this utility model, the absorbent cotton core continuously absorbs the fragrance liquid from the perfume container, rises to the top through capillary action, and the fragrance is released by the first fragrance diffuser cotton pad. The fragrance is evenly diffused into the car through the V-shaped vent on the top cover. A small amount of splashing or vapor condensation is blocked by the V-shaped ring and absorbed by the second fragrance diffuser cotton pad. This not only prevents the liquid from contacting the inner wall of the top cover and causing pollution, but also uses the cotton pad for secondary slow-release diffusion, thereby improving the stability and longevity of the fragrance.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a leak-proof structure for a car perfume container, including a lower cover 5, which is screwed onto the perfume container body and serves as a base for liquid containment and diversion; an upper cover 1 is screwed onto the lower cover 5, and the upper cover 1 has several V-shaped venting openings 101 (opening towards the center), which facilitates aroma diffusion and reduces external liquid splashing; a funnel-shaped protrusion 8 and a stepped tube 9 are integrally formed on the lower end of the inner wall of the lower cover 5, the funnel-shaped protrusion 8 guides the overflowing liquid to flow in a concentrated direction, an absorbent cotton core 4 is inserted into the stepped tube 9, and a first fragrance-diffusing cotton sheet 3 is placed at the top of the stepped tube 9 as the main fragrance-diffusing layer, and a sealing ring 6 is fitted on the stepped tube 9 to cooperate with the lower cover 5 and the perfume container to ensure the overall sealing after screwing and prevent the fragrance liquid from leaking from the interface.

[0017] Specifically, such as Figure 2 and Figure 3 As shown, multiple first leakage channels 801 are formed around the central axis inside the funnel-shaped boss 8, and a second leakage channel 901 is formed between the inner and outer walls of the stepped tube 9 around the central axis. The upper end of the first leakage channel 801 passes through the funnel-shaped boss 8, and the lower end connects to the second leakage channel 901. The bottom end of the second leakage channel 901 has a constricted structure to form a slow flow damping and prevent the backflow liquid from splashing again due to shaking.

[0018] Specifically, such as Figure 2 and Figure 3As shown, the bottom of the upper cover 1 is fixedly connected to a pressure ring 7 that abuts against the first fragrance diffuser 3. The pressure ring 7 includes a connecting ring 71 fixedly connected to the upper cover 1, and an inwardly opening V-shaped ring 72 fixedly connected to the connecting ring 71. The V-shaped ring 72 expands the space above the first fragrance diffuser 3 to prevent liquid from splashing due to capillary action or shaking. An annular boss 73 is fixedly connected to the outside of the V-shaped ring 72. A second fragrance diffuser 2 is fitted on the annular boss 73 to absorb any excess fragrance liquid that may overflow and to assist in diffuser diffusion, thereby improving the stability and longevity of the fragrance.

[0019] Working principle: When in use, firstly, the absorbent cotton core 4 continuously absorbs the fragrance liquid from the perfume container, rises to the top through capillary action, and the fragrance is released by the first fragrance diffuser cotton 3. The fragrance is evenly diffused into the car through the V-shaped vent 101 of the top cover 1. Secondly, when the vehicle is bumpy, the temperature rises and the fragrance evaporates too quickly or the cotton core is saturated, the excess fragrance may overflow from the first fragrance cotton pad 3 and drip onto the surface of the funnel-shaped protrusion 8 below. The overflowing liquid collects along the slope of the funnel, flows into the second leakage tank 901 through the first leakage tank 801, and finally slowly flows back into the perfume container through the constricted bottom end, realizing the automatic recovery of the overflowing fragrance and significantly reducing the risk of leakage. A small amount of splashed or condensed liquid is blocked by the V-shaped ring 72 and absorbed by the second fragrance diffuser pad 2. This not only prevents the liquid from contacting the inner wall of the top cover 1 and causing contamination, but also uses the pad for secondary slow-release diffusion of fragrance, thereby improving the stability and longevity of the fragrance.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
