Description

Technical Field

[0001] The technical field of this utility model relates to, in particular to, an aromatherapy bottle. Background Technology

[0002] Aroma diffusers, as a common household item, are widely used for indoor fragrance control and air purification. Traditional aroma diffusers typically use a single-layer structure, slowly releasing the fragrance liquid into the air through a wick or diffuser. However, this structure has a significant drawback: when the diffuser is accidentally dropped or tilted, the fragrance liquid inside is prone to leakage, causing waste and potentially staining furniture or floors. This leakage problem is particularly severe when using highly volatile fragrance liquids.

[0003] Existing leak-proof designs often employ methods such as increasing the seal at the bottle opening or using leak-proof valves. However, these methods are often complex and costly, and their effectiveness in practical use is limited. Furthermore, while some designs can prevent leakage to some extent, they can affect the normal evaporation of the fragrance liquid, leading to uneven or excessively slow fragrance release. Therefore, there is an urgent need for a new type of fragrance bottle design that can effectively prevent leakage without affecting the normal evaporation of the fragrance liquid. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a two-stage leak-proof system that can prevent leakage when an aromatherapy bottle is dropped.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an aromatherapy bottle, including a bottle body, a bottle cap, and a leak-proof component disposed at the opening of the bottle cap. The leak-proof component includes a primary sleeve, a primary sealing cylinder, a secondary sleeve, and a secondary sealing cylinder connected in sequence downwards. A primary sealing strip is provided with an inwardly protruding bottom edge of the primary sleeve, and a secondary sealing strip is provided with an inwardly protruding bottom edge of the secondary sleeve. A primary sealing ball is disposed inside the primary sealing cylinder, and a secondary sealing ball is disposed inside the secondary sealing cylinder. The primary sealing ball and the secondary sealing ball are respectively able to move up and down within the primary sealing cylinder and the secondary sealing cylinder due to gravity.

[0006] Preferably, the diameters of the primary sleeve, the primary sealing ball, the secondary sealing cylinder, and the secondary sealing ball are the same.

[0007] Preferably, the diameters of both the primary sealing strip and the secondary sealing strip are smaller than the diameter of the primary sealing ball.

[0008] Preferably, the primary sealing cylinder and the secondary sealing cylinder have the same diameter, and both of their diameters are larger than the diameters of the primary sleeve and the secondary sleeve.

[0009] Preferably, a primary support ring and a secondary support ring are respectively provided at the bottom of the primary sealing cylinder and the secondary sealing cylinder; the diameter of the primary support ring and the secondary support ring is smaller than the diameter of the primary sealing ball.

[0010] Preferably, both the primary sealing cylinder and the secondary sealing cylinder are provided with limiting sleeves; the primary sealing ball and the secondary sealing ball are disposed within the limiting sleeves and slide up and down by gravity.

[0011] Preferably, the limiting sleeve includes an upper ring, a lower ring, and a connecting post; the upper ring is disposed at the bottom of the first-stage sleeve, the lower ring is disposed at the bottom of the first-stage sealing cylinder, and the two ends of the connecting post are respectively connected to the upper ring and the lower ring.

[0012] Preferably, the upper ring is fitted and sleeved on the outside of the primary sealing strip, and the lower ring is sleeved on the outside of the primary support ring and the secondary support ring.

[0013] Preferably, the lower ring and the first-stage support ring are connected to the first-stage sealing cylinder via a transverse column.

[0014] Preferably, the primary sealing cylinder and the secondary sealing cylinder each have a first sealing cavity and a second sealing cavity.

[0015] The beneficial effects of this invention are: double leak-proof protection. The inverted, two-stage leak-proof aromatherapy bottle adopts a double-layer leak-proof structure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model. Example

[0024] Reference Figure 1-7 As illustrated, this embodiment proposes an aromatherapy bottle that achieves automatic sealing through a double-layer leak-proof structure and gravity, effectively preventing leakage when the bottle is dropped or tilted. Its structure is simple, easy to use, and suitable for various types of aromatherapy liquids. The specific implementation of this embodiment is described in detail below with reference to the accompanying drawings. This embodiment's inverted two-stage leak-proof aromatherapy bottle includes a bottle body 100, a cap 200, and a leak-proof component 300 disposed at the opening of the cap 200.

[0025] The bottle body 100 is the main part of the aromatherapy bottle, used to hold the aromatherapy liquid. The bottle body 100 is typically made of a transparent or semi-transparent material, such as glass or highly transparent plastic, so that the user can observe the remaining amount of aromatherapy liquid. The top of the bottle body 100 has a threaded connection for attaching to the cap 200. The bottom of the bottle body 100 can be designed to be flat or curved to ensure the aromatherapy bottle can be placed stably.

[0026] The bottle cap 200 is used to seal the bottle body 100 and has an internal leak-proof component 300. The outer side of the bottle cap 200 may be designed with a smooth surface or with anti-slip texture to facilitate tightening or loosening by the user. The inner side of the bottle cap 200 has threads that match the threaded interface of the bottle body 100, ensuring that the bottle cap 200 can be securely fixed to the bottle body 100.

[0027] The bottle body 100 and the bottle cap 200 are connected by threads to ensure sealing and stability. During assembly, the user simply aligns the bottle cap 200 with the threaded interface of the bottle body 100 and tightens it by rotating it clockwise. To prevent the bottle cap 200 from loosening, a sealing ring or sealant can be added to the threaded connection to further improve the sealing effect.

[0028] Furthermore, the leak-proof component 300 is the core part of this embodiment, employing a double-layer leak-proof structure and achieving automatic sealing through gravity. The leak-proof component 300 includes a primary sleeve 301, a primary sealing cylinder 302, a secondary sleeve 303, and a secondary sealing cylinder 304. The structure and function of each part are described in detail below.

[0029] The leak-proof assembly 300 includes a primary sleeve 301, a primary sealing cylinder 302, a secondary sleeve 303, and a secondary sealing cylinder 304 connected sequentially downwards; wherein a primary sealing strip 301a is provided with an inwardly protruding primary edge at the bottom edge of the primary sleeve 301, a secondary sealing strip 303a is provided with an inwardly protruding secondary edge at the bottom edge of the secondary sleeve 303, a primary sealing ball 302a is provided inside the primary sealing cylinder 302, and a secondary sealing ball 304a is provided inside the secondary sealing cylinder 304; the primary sealing ball 302a and the secondary sealing ball 304a can move up and down in the primary sealing cylinder 302 and the secondary sealing cylinder 304 respectively due to gravity.

[0030] The primary sleeve 301, primary sealing ball 302a, secondary sealing cylinder 304, and secondary sealing ball 304a have the same diameter. The diameters of the primary sealing strip 301a and secondary sealing strip 303a are both smaller than the diameter of the primary sealing ball 302a. The primary sealing cylinder 302 and secondary sealing cylinder 304 have the same diameter, and both have a larger diameter than the primary sleeve 301 and secondary sleeve 303.

[0031] In one optimized embodiment, a primary support ring 302b and a secondary support ring 304b are respectively provided at the bottom of the primary sealing cylinder 302 and the secondary sealing cylinder 304. The diameters of the primary support ring 302b and the secondary support ring 304b are smaller than the diameter of the primary sealing ball 302a.

[0032] Both the primary sealing cylinder 302 and the secondary sealing cylinder 304 are equipped with limiting sleeves 305; the primary sealing ball 302a and the secondary sealing ball 304a are set inside the limiting sleeves 305 and slide up and down by gravity.

[0033] Furthermore, the limiting sleeve 305 includes an upper ring 305a, a lower ring 305b, and a connecting post 305c. The upper ring 305a is located at the bottom of the primary sleeve 301, and the lower ring 305b is located at the bottom of the primary sealing cylinder 302. The connecting post 305c connects the upper ring 305a and the lower ring 305b at both ends. The upper ring 305a is fitted snugly to the outside of the primary sealing strip 301a, and the lower ring 305b is spaced out to the outside of the primary support ring 302b and the secondary support ring 304b. The lower ring 305b and the primary support ring 302b are connected to the primary sealing cylinder 302 via a transverse post 306.

[0034] It should be noted that the primary sleeve 301 is the upper structure of the leak-proof assembly 300, and its bottom edge protrudes inward to form a primary sealing strip 301a. The diameter of the primary sealing strip 301a is smaller than the diameter of the primary sealing ball 302a, and it is used to form a seal when the primary sealing ball 302a falls due to the force of the impact after the bottle is dropped. Similarly, the secondary sleeve 303 is located below the primary sealing sleeve 302, and its bottom edge protrudes inward to form a secondary sealing strip 303a. The diameter of the secondary sealing strip 303a is smaller than the diameter of the secondary sealing ball 304a, and it is used to form a seal when the secondary sealing ball 304a falls.

[0035] The primary sealing cylinder 302 is located below the primary sleeve 301, and a primary sealing ball 302a is disposed inside it. The primary sealing ball 302a can move up and down under the action of gravity. A primary support ring 302b is provided at the bottom of the primary sealing cylinder 302 to limit the falling position of the primary sealing ball 302a. Similarly, the secondary sealing cylinder 304 is located below the secondary sleeve 303, and a secondary sealing ball 304a is disposed inside it. The secondary sealing ball 304a can move up and down under the action of gravity. A secondary support ring 304b is provided at the bottom of the secondary sealing cylinder 304 to limit the falling position of the secondary sealing ball 304a.

[0036] Furthermore, a limiting sleeve 305 is disposed within the primary sealing cylinder 302 and the secondary sealing cylinder 304 to limit the movement range of the primary sealing ball 302a and the secondary sealing ball 304a. The limiting sleeve 305 includes an upper ring 305a, a lower ring 305b, and a connecting post 305c.

[0037] The upper ring 305a is fitted over the outer side of the primary sealing strip 301a to ensure that the primary sealing ball 302a does not block the primary sleeve 301 under normal conditions. The lower ring 305b is fitted over the outer side of the primary support ring 302b and the secondary support ring 304b to limit the falling position of the primary sealing ball 302a and the secondary sealing ball 304a. The connecting post 305c is connected to the upper ring 305a and the lower ring 305b at both ends to ensure the stability of the limiting sleeve 305 and that the diameter of the moving cylindrical space of the limiting sleeve 305 is equal to the diameter of the primary sealing ball 302a and the secondary sealing ball 304a.

[0038] The transverse column 306 connects the lower ring 305b and the primary support ring 302b to enhance the stability of the limiting sleeve 305 and prevent the primary sealing ball 302a and the secondary sealing ball 304a from shifting during movement.

[0039] In this embodiment, the primary sealing cylinder 302 and the secondary sealing cylinder 304 each have a first sealing cavity 302c and a second sealing cavity 304c. Specifically, the primary sealing cylinder 302 and the secondary sealing cylinder 304 each have a first sealing cavity 302c and a second sealing cavity 304c. When the aromatherapy bottle is in a normal upright position, the primary sealing ball 302a and the secondary sealing ball 304a are located at the top of the first sealing cavity 302c and the second sealing cavity 304c, respectively, and the aromatherapy liquid evaporates normally through the evaporation core. When the aromatherapy bottle is dropped or tilted, the primary sealing ball 302a and the secondary sealing ball 304a fall under the action of gravity, blocking the primary sealing strip 301a and the secondary sealing strip 303a, respectively, forming a double seal to prevent liquid leakage.
