Description

Technical Field

[0001] This utility model relates to the field of fragrance evaluation technology, specifically a device for evaluating the diffusion properties of fragrances and aromatherapy products. Background Technology

[0002] In the research and development of fragrances and aromatherapy products, aroma evaluation is often involved. Currently, the commonly used aroma evaluation methods are mainly as follows: 1. Using a smelling stick to apply a small amount of fragrance and bring it close to the nose to evaluate the pleasantness and intensity of the fragrance or liquid aromatherapy product; 2. Preparing the fragrance into a liquid or solid aromatherapy product, placing it in a small bottle, opening the sealed cap, and bringing it close to the nose to evaluate the pleasantness and intensity of the aromatherapy product; 3. Preparing the fragrance into a liquid or solid aromatherapy product, placing it in an aroma evaluation room for a certain period of time, and evaluating the intensity of the aroma through a small window in the aroma evaluation room.

[0003] The above-mentioned fragrance evaluation methods mainly focus on the overall pleasantness and intensity of the fragrance, as well as the performance of the aromatherapy product when opened and in a small space. They do not provide a more objective evaluation of the diffusion properties of the fragrance or aromatherapy product.

[0004] During use, it is often found that even fragrances and aromatherapy products that pass product testing still receive reviews indicating insufficient aroma intensity. This actually relates to the issue of aroma diffusion distance. These problems are often related to the diffusion of the aroma. If the aroma diffuses well, consumers can still perceive the fragrance from a greater distance from the source, resulting in a better consumer experience.

[0005] However, this part of the evaluation is difficult to conduct using objective data within a limited space. In order to evaluate the diffusion performance of fragrances or aromatherapy products in space, it is necessary to develop a device for evaluating the diffusion performance of fragrances and aromatherapy products. Utility Model Content

[0006] The purpose of this invention is to provide a device for evaluating the diffusion properties of fragrances and aromatherapy products, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fragrance and aromatherapy product diffusion evaluation device, comprising: a fragrance or aromatherapy product storage container, wherein the upper opening of the fragrance or aromatherapy product storage container is connected to an aroma diffusion tube; the aroma diffusion tube is perpendicular to the ground, and multiple aroma-smelling ports are vertically arranged along the central axis of the aroma diffusion tube, and sealing caps are provided at the outlets of the multiple aroma-smelling ports; a top fan is provided above the end of the aroma diffusion tube away from the fragrance or aromatherapy product storage container, and the airflow direction of the top fan outlet is perpendicular to the aroma diffusion tube; a timer is provided next to the aroma diffusion tube.

[0008] Preferably, the plurality of aroma-smelling openings, from bottom to top, include a first aroma-smelling opening, a second aroma-smelling opening, a third aroma-smelling opening, a fourth aroma-smelling opening, and a fifth aroma-smelling opening. The distance between the first aroma-smelling opening and the second aroma-smelling opening is 250-300mm, the distance between the first aroma-smelling opening and the third aroma-smelling opening is 500-550mm, the distance between the first aroma-smelling opening and the end furthest from the storage container of the fragrance or aromatherapy product is 2000-2050mm.

[0009] Preferably, the connection between the top opening of the fragrance or aromatherapy product storage container and the aroma diffusion tube is made by a quick-release buckle, and a sealing gasket is provided between the top opening of the fragrance or aromatherapy product storage container and the aroma diffusion tube.

[0010] Preferably, the aroma diffusion tube is made of food-grade stainless steel, the diameter of the aroma diffusion tube is 20-25mm, and the diameter of the aroma-smelling port is 15-20mm.

[0011] Preferably, the storage container for the fragrance or aromatherapy product is a narrow-mouthed glass container, including but not limited to a 50mL ground glass flask, a 50mL conical flask, or a 50mL eggplant flask.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by horizontally setting a top fan at the top of the aroma diffusion tube and connecting the bottom of the aroma diffusion tube to a storage container for fragrance or aromatherapy products, creates a weak air pressure difference between the top and bottom of the aroma diffusion tube due to the horizontal airflow caused by the top fan. The air at the bottom carries the aroma to the top due to the pressure difference. As time changes, the aroma of the fragrance or aromatherapy product storage container will be successively detected at the smelling ports at different heights. By testing different fragrances or aromatherapy products under the same conditions and recording the time it takes for the aroma to reach the smelling ports at different heights using a timer, the diffusion of the tested sample can be evaluated more objectively.

[0013] Compared with a fragrance evaluation room, this utility model provides a fragrance and aromatherapy product diffusion evaluation device that occupies less space and can quickly and objectively evaluate the diffusion of fragrances and aromatherapy products. It can better judge the spatial performance of fragrances and aromatherapy products in a limited space, helping perfumers and product developers to quickly, intuitively and objectively evaluate the diffusion of products and guide the modification of fragrances and finished products.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 This utility model provides a technical solution: a fragrance and aromatherapy product diffusion evaluation device, comprising: a fragrance or aromatherapy product storage container 1, the top opening of the fragrance or aromatherapy product storage container 1 being connected to an aroma diffusion tube 3; the aroma diffusion tube 3 being perpendicular to the ground, having multiple smelling ports vertically arranged along its central axis, and having sealing caps 10 at the outlets of the multiple smelling ports; a top fan 9 being provided above the end of the aroma diffusion tube 3 away from the fragrance or aromatherapy product storage container 1, the airflow direction of the top fan 9 being perpendicular to the aroma diffusion tube 3; and a timer 12 being provided beside the aroma diffusion tube 3.

[0018] Specifically, the multiple aroma-smelling openings, from bottom to top, include a first aroma-smelling opening 4, a second aroma-smelling opening 5, a third aroma-smelling opening 6, a fourth aroma-smelling opening 7, and a fifth aroma-smelling opening 8. The distance between the first aroma-smelling opening 4 and the second aroma-smelling opening 5 is 250-300mm, the distance between the first aroma-smelling opening 4 and the third aroma-smelling opening 6 is 500-550mm, the distance between the first aroma-smelling opening 4 and the fourth aroma-smelling opening 7 is 1000-1050mm, the distance between the first aroma-smelling opening 4 and the fifth aroma-smelling opening 8 is 1500-1550mm, and the distance between the first aroma-smelling opening 4 and the end furthest from the storage container 1 of the fragrance or aromatherapy product is 2000-2050mm.

[0019] It's important to note that smelling nozzles at different heights can be used to compare the intensity of the aroma at different locations in space. Due to the diffusion and dilution of aroma molecules in the air, the intensity of the aroma decreases with increasing distance from the source. By comparing the aroma intensity at different smelling nozzles, the persistence and diffusion ability of the aroma can be assessed.

[0020] The connection between the top opening of the fragrance or aromatherapy product storage container 1 and the aroma diffusion tube 3 is made by a quick-release buckle 2, and a sealing gasket 11 is provided between the top opening of the fragrance or aromatherapy product storage container 1 and the aroma diffusion tube 3.

[0021] It should be noted that the quick-release buckle 2 allows for easy replacement of the fragrance or aromatherapy product storage container 1, and the main function of the sealing gasket 11 is to prevent gas leakage at the connection point, forming a leak-proof seal.

[0022] The aroma diffusion tube 3 is made of food-grade stainless steel. The diameter of the aroma diffusion tube 3 is 20-25mm, and the diameter of the aroma mouth is 15-20mm. The fragrance or aromatherapy product storage container 1 is a small-mouth glass container.

[0023] This invention features a top fan horizontally positioned at the top of an aroma diffuser tube, with a fragrance or aromatherapy product storage container connected to the bottom. The horizontal airflow created by the top fan generates a weak pressure difference between the top and bottom of the diffuser tube, causing the air at the bottom to carry the aroma towards the top. Over time, the aroma from the fragrance or aromatherapy product storage container is detected at different olfactory openings. By testing different fragrances or aromatherapy products under identical conditions and recording the time it takes for the aroma to reach different olfactory openings using a timer, the diffusion of the tested sample can be evaluated more objectively.

[0024] Example 1

[0025] Flameless aromatherapy diffuser A consists of 20% white tea flavoring, 20% dipropylene glycol methyl ether acetate, and 60% isododecane; flameless aromatherapy diffuser B consists of 20% white tea flavoring and 80% dipropylene glycol methyl ether acetate. Take 1 mL of each sample and place it in the fragrance or aromatherapy product container 1. Connect the fragrance or aromatherapy product container 1 to the aroma diffusion tube 3 using the quick-release clip 2. Turn on the top fan 9 and start timing using timer 12. Record the aroma of each fragrance every 20 minutes. The test results are shown in the table below.

[0026]

[0027] The experimental results show that flameless aromatherapy diffuser A has a better diffusion effect and a wider fragrance range in the product.

[0028] Compared with a fragrance evaluation room, this utility model occupies less space and can quickly and objectively evaluate the diffusion properties of fragrances and aromatherapy products. It can better judge the spatial expressiveness of fragrances and aromatherapy products in a limited space, helping perfumers and product developers to quickly, intuitively and objectively evaluate the diffusion properties of products and guide the modification of fragrances and finished products.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
