Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a perfume mixing bottle with multiple independent storage chambers, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A perfume mixing bottle with multiple independent chambers includes: a support frame, a bottle body mounted on the support frame, a stirring assembly mounted inside the bottle body, a discharge assembly connected to the bottom of the bottle body, multiple feeding assemblies connected to the top of the bottle body, and a filter element connected to the tail of the discharge assembly.

[0008] The bottle contains a mixing chamber and multiple sector-shaped storage chambers. The sector-shaped storage chambers are located above the mixing chamber. The lower part of the stirring assembly rotates and fits inside the mixing chamber. The discharge assembly is connected to the mixing chamber, and the feeding assembly is connected to the corresponding sector-shaped storage chamber. A filling hole is provided between the sector-shaped storage chamber and the mixing chamber. A pressing component corresponding to the sector-shaped storage chamber is elastically fitted on the top of the bottle. A lifting column is installed on the lower end face of the pressing component. The lifting column vertically passes through the filling hole. An annular liquid extraction groove is provided around the lifting column and is connected to the sector-shaped storage chamber.

[0009] Optionally, the support frame includes a fixing ring installed around the bottle body, four support legs installed on the side of the fixing ring, and a base plate installed on the lower end face of the support legs, the base plate being located below the discharge assembly and the filter element.

[0010] Optionally, the lifting column is equipped with two sealing rings on its periphery, and the annular liquid collection groove is located between the upper and lower sealing rings. One sealing ring is located in the fan-shaped storage chamber, and the other sealing ring is located in the mixing and blending chamber and is in contact with the upper surface of the mixing and blending chamber wall.

[0011] Optionally, the pressing component includes an extension rod installed on the upper end face of the lifting column, the upper end of the extension rod extending through to the outside of the bottle body, a pressing head provided on the upper end face of the extension rod, the pressing head being located above the bottle body, a limiting cylinder installed on the upper side of the fan-shaped storage chamber, the limiting cylinder being located around the extension rod, an annular extrusion plate slidably fitted within the limiting cylinder being provided around the extension rod, a spring being provided between the annular extrusion plate and the lower end face of the inner wall of the limiting cylinder, the spring being sleeved around the extension rod.

[0012] Optionally, the discharge assembly includes an L-shaped bend connected to the bottom of the bottle body, the L-shaped bend being connected to the mixing chamber, a first valve being provided on the L-shaped bend, and a filter element being connected to one end of the L-shaped bend.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] The layered layout of the mixing and blending chamber and multiple fan-shaped storage chambers facilitates the independent storage of different perfume raw materials and enables unidirectional flow control. The pressing component drives the lifting column, which in turn moves the annular liquid dispensing tank through the filling hole, facilitating the quantitative release of perfume raw materials from the fan-shaped storage chambers into the mixing and blending chamber, thus improving the convenience of perfume blending. The lifting column seals the filling hole, reducing the risk of excessive leakage of perfume raw materials from the fan-shaped storage chambers due to a single press of the pressing component. Combined with the stirring component, the perfume raw materials in the mixing and blending chamber are rotated and stirred, improving the uniformity of mixing. At the same time, the combined design of the discharge component and the filter component facilitates the interception of impurities in the perfume.

Detailed Implementation

[0027] 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.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the field of perfume blending, existing technologies often employ a single mixing chamber structure. For example, a traditional blending tank typically consists of a tank body, a stirrer, and an inlet. During operation, different raw materials must be manually measured and sequentially added into the tank through the inlet for mixing. While this design fulfills the basic mixing function, it has significant limitations in practical applications: First, because the raw materials need to be pre-packaged in external containers, perfumers must repeatedly weigh and transfer the liquid, which is not only cumbersome but also prone to errors leading to imbalances in the proportions. Second, the proportions of raw materials cannot be adjusted in real time during mixing; if too much is added, the mixture must be re-blended, resulting in material waste. Some improved devices attempt to enhance operational convenience by adding multiple inlet pipes, such as several independent inlets on the top of the tank, allowing simultaneous connection to different raw material containers. However, this design still relies on external storage devices, and liquid residue at pipe connections can easily lead to cross-contamination. Furthermore, it lacks a quantitative control mechanism, requiring manual intervention in the actual amount added, making it difficult to meet the demands of high-precision formulations.

[0030] To further optimize mixing, some existing devices have incorporated dynamic stirring structures. For example, a double-layered stirring blade design uses a motor-driven shaft to rotate the blades, creating vortices within the tank to accelerate mixing. While this structure improves mixing uniformity, the shear forces generated during stirring can damage volatile components in the perfume ingredients, affecting the aroma's complexity. Furthermore, bubbles generated during stirring, if not promptly eliminated, can remain in the finished product, reducing transparency. To address this, some devices add a circulating filtration system at the bottom of the tank. A pump draws the mixture to an external filter to remove impurities and bubbles, before returning it to the tank. However, such external circulation systems not only increase equipment complexity and energy consumption but also pose a risk of leakage at pipe connections. Additionally, the filters require frequent disassembly and cleaning, resulting in high maintenance costs.

[0031] Regarding raw material storage, existing technologies have attempted to combine storage functions with mixing chambers. For example, a surround-type storage tank design is used, with multiple independent chambers arranged around the mixing tank, each connected to the main mixing chamber via valves. During operation, solenoid valves control the timing and flow rate of raw material release from different chambers. While this design allows for temporary storage of raw materials, it relies on an electronic control system, resulting in a complex structure and extremely high sealing requirements; even a minor valve malfunction can lead to cross-contamination or leakage. Furthermore, the switching accuracy of solenoid valves is significantly affected by liquid viscosity. For high-viscosity liquids such as essential oils commonly found in perfume raw materials, flow fluctuations or residue issues are prone to occur, making stable volume control difficult. In addition, these devices are often made of hard metal or plastic, making it difficult to observe the remaining raw material level within the chambers. Manual replenishment requires external measuring tools, compromising operational convenience.

[0032] To address the issue of impurity filtration, existing technologies commonly employ multi-stage filtration schemes. For example, removable filters are installed at the outlet, or a sedimentation zone is set up at the bottom of the mixing chamber to collect particulate matter. However, filter structures are easily clogged by fine impurities, requiring frequent shutdowns for cleaning, while sedimentation zone designs are only suitable for denser impurities, offering limited effectiveness in intercepting suspended particles. Some high-end equipment attempts to integrate centrifugal separation technology, using centrifugal force generated by high-speed rotation to separate impurities. However, such solutions involve bulky equipment, high energy consumption, and stringent requirements on liquid flowability, making them unsuitable for the low-flow-rate, high-precision operations common in perfume blending. Furthermore, the heat generated during centrifugation may accelerate the dissipation of volatile components in the perfume, affecting the longevity of the finished fragrance.

[0033] From a user experience perspective, existing blending devices are largely geared towards industrial production scenarios, with large equipment sizes and complex user interfaces, making them unsuitable for small studios or individual perfumers. For example, common large blending tanks exceed one meter in height, requiring fixed installation and relying on external power, resulting in insufficient mobility and flexibility. Although some portable devices simplify their structure by reducing size, they often sacrifice raw material storage capacity or mixing efficiency. For instance, single-chamber designs can only blend one formula at a time, failing to enable parallel preparation of multiple formulas or rapid switching of raw materials. Furthermore, the cleaning and maintenance processes for existing equipment are cumbersome, especially for models with complex piping or electronic components, where disassembly and reassembly are time-consuming, impacting continuous operation efficiency.

[0034] It is worth noting that some existing technologies are beginning to focus on the digital management of raw material proportions, such as monitoring the injection volume through flow sensors and automatically adjusting valve openings in conjunction with a control system. While such intelligent solutions can improve proportioning accuracy, they rely on precision sensors and a stable power supply, leading to decreased reliability in humid or vibrating environments and significantly increased manufacturing costs, making them difficult to popularize among small and medium-sized users. Furthermore, the introduction of electronic components challenges the equipment's waterproof and dustproof performance, especially in the mixing process where frequent contact with liquids poses a high risk of circuit board corrosion, thus limiting equipment lifespan. Therefore, how to achieve precise quantity control while simplifying the structure and reducing costs remains a challenge that existing technologies have not yet effectively solved.

[0035] In summary, existing perfume blending equipment still faces multiple technical bottlenecks in core aspects such as raw material storage, quantitative release, mixing efficiency, and impurity handling. Most devices rely on external storage containers, resulting in insufficient precision in raw material addition during mixing; filtration systems are complex and difficult to maintain; and intelligent solutions are costly and have poor environmental adaptability. These shortcomings make it difficult for existing equipment to meet the core demands of modern perfumery processes for efficiency, precision, and convenience. Especially in personalized customization and small-batch production scenarios, users urgently need an integrated device that can independently store multiple raw materials, achieve precise proportions, and simultaneously complete mixing and filtration.

[0036] Please see Figure 1-4 As shown, this embodiment provides a perfume mixing bottle with multiple independent chambers, including: a support frame, a bottle body 1 is provided on the support frame, a stirring assembly is provided inside the bottle body 1, a discharge assembly is connected to the bottom of the bottle body 1, multiple feeding assemblies are connected to the top of the bottle body 1, and a filter element is connected to the tail of the discharge assembly.

[0037] The bottle body 1 is provided with a mixing and blending chamber 12 and multiple sector-shaped storage chambers 11. The sector-shaped storage chambers 11 are located above the mixing and blending chamber 12. The lower part of the stirring assembly is rotatably fitted in the mixing and blending chamber 12. The discharge assembly is connected to the mixing and blending chamber 12, and the feeding assembly is connected to the corresponding sector-shaped storage chamber 11. A filling hole 13 is provided between the sector-shaped storage chamber 11 and the mixing and blending chamber 12. A pressing component corresponding to the sector-shaped storage chamber 11 is elastically fitted on the top of the bottle body 1. A lifting column 20 is installed on the lower end face of the pressing component. The lifting column 20 vertically penetrates the filling hole 13. An annular liquid extraction groove 21 is provided around the lifting column 20. The annular liquid extraction groove 21 is connected to the sector-shaped storage chamber 11.

[0038] One application of this embodiment is as follows: In use, different perfume raw materials are first injected into the corresponding fan-shaped storage chambers 11 through multiple feeding components. When mixing is required, the pressing component at the top of the corresponding fan-shaped storage chamber 11 is pressed, causing it to push the lower lifting column 20 downward. At this time, the annular liquid-collecting groove 21 on the side of the lifting column 20 enters the filling hole 13 as it descends. The annular liquid-collecting groove 21 contains a certain amount of perfume raw materials. After the annular liquid-collecting groove 21 passes through the filling hole 13 and connects with the mixing chamber 12, the perfume in the annular liquid-collecting groove 21 flows into the lower mixing chamber 12. After releasing the pressing component, the lifting column 20 rises back to its original position under the action of elasticity, carrying the annular liquid-collecting groove 21. Then, the stirring component is activated, causing its lower part to rotate and stir the perfume raw materials in the mixing chamber 12. After mixing is completed, the perfume flows out through the bottom discharge component and is filtered through the tail filter. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.

[0039] The layered layout of the mixing chamber 12 and multiple fan-shaped storage chambers 11 facilitates the independent storage of different perfume raw materials and enables unidirectional flow control. The lifting column 20 is driven by the pressing component to drive the annular liquid dispensing tank 21 through the filling hole 13, which facilitates the quantitative release of perfume raw materials in the fan-shaped storage chambers 11 into the mixing chamber 12, improving the convenience of perfume blending. The lifting column 20 closes the filling hole 13, reducing the risk of excessive flow of perfume raw materials in the fan-shaped storage chambers 11 due to a single press of the pressing component. Combined with the stirring component, the perfume raw materials in the mixing chamber 12 are rotated and stirred to improve the uniformity of mixing. At the same time, the combined design of the discharge component and the filter component facilitates the interception of impurities in the perfume.

[0040] like Figure 1 , 2 As shown, the support frame in this embodiment includes a fixing ring 8 installed around the bottle body 1. Four support legs 9 are installed on the side of the fixing ring 8. A base plate 10 is installed on the lower end face of the support legs 9. The base plate 10 is located below the discharge assembly and the filter element. The support frame structure formed by the fixing ring 8, the support legs 9, and the base plate 10 facilitates stable support of the bottle body 1 and the discharge assembly, reduces the risk of equipment tipping over, and increases the contact area between the support legs 9 and the ground by the base plate 10, thereby improving the stability of the equipment during use.

[0041] like Figure 2 , 4As shown, in this embodiment, the lifting column 20 is equipped with two sealing rings 22 around its periphery. The annular liquid dispensing groove 21 is located between the upper and lower sealing rings 22. One sealing ring 22 is located in the fan-shaped storage chamber 11, and the other sealing ring 22 is located in the mixing chamber 12 and is in contact with the upper end face of the inner wall of the mixing chamber 12. Through the upper and lower distributed sealing rings 22, it is convenient to reduce the probability of perfume raw materials leaking along the gap between the lifting column 20 and the dispensing hole 13 by utilizing the contact effect between the two sealing rings 22 and the inner wall of the fan-shaped storage chamber 11 and the mixing chamber 12, respectively, after pressing and when not pressing.

[0042] like Figure 2 , 4 As shown, the pressing component in this embodiment includes an extension rod 23 mounted on the upper end face of the lifting column 20. The upper end of the extension rod 23 extends to the outside of the bottle body 1. A pressing head 24 is provided on the upper end face of the extension rod 23. The pressing head 24 is located above the bottle body 1. A limiting cylinder 26 is installed on the upper side of the fan-shaped storage chamber 11. The limiting cylinder 26 is located around the extension rod 23. An annular extrusion plate 25 is provided around the extension rod 23 and is slidably fitted inside the limiting cylinder 26. A spring 27 is provided between the annular extrusion plate 25 and the lower end face of the inner wall of the limiting cylinder 26. The spring 27 is sleeved around the extension rod 23. The annular extrusion plate 25 cooperates with the limiting cylinder 26 to limit the lifting stroke of the extension rod 23. At the same time, it cooperates with the spring 27 to facilitate the rapid upward reset after the pressing head 24 is released.

[0043] like Figure 1 , 2 As shown, the discharge assembly of this embodiment includes an L-shaped bend 2 connected to the bottom of the bottle body 1. The L-shaped bend 2 is connected to the mixing chamber 12. A first valve 3 is provided on the L-shaped bend 2. A filter element is connected to one end of the L-shaped bend 2. The L-shaped bend 2 and the first valve 3 cooperate to facilitate the control of the discharge start and stop of the mixing chamber 12.

[0044] like Figure 1 , 2 As shown, the filter element in this embodiment includes a cylinder 4. One end face of the cylinder 4 is provided with an external screw cylinder 5 that is threaded into an L-shaped bend 2. A filter plate 6 is provided on the inner wall of the cylinder 4. A plurality of anti-slip textures 7 are evenly provided on the circumference of the cylinder 4. The external screw cylinder 5 is threadedly connected to the L-shaped bend 2, which facilitates the disassembly of the cylinder 4 for cleaning or replacement, thereby improving the maintenance efficiency of the filter element. At the same time, the anti-slip textures 7 enhance the grip friction during operation and reduce the risk of slipping during disassembly.

[0045] like Figure 1-3As shown, the feeding assembly of this embodiment includes a replenishment pipe 17 connected to the upper end face of the bottle body 1. The replenishment pipe 17 is connected to the corresponding sector-shaped storage chamber 11. A second valve 18 is provided on the replenishment pipe 17. A flange 19 is provided on the upper periphery of the replenishment pipe 17. By cooperating with the second valve 18, it is convenient to independently control the replenishment of perfume raw materials into each sector-shaped storage chamber 11. The flange 19 can be used to connect the replenishment pipe 17 to an external feeding pipeline.

[0046] like Figure 2 , 3 As shown, the stirring assembly in this embodiment includes a motor 14 disposed inside the bottle body 1, a fan-shaped storage chamber 11 located on the side of the motor 14, a shaft 15 fixedly connected to the output shaft of the motor 14, and a plurality of stirring rods 16 disposed on the side of the shaft 15. The lower end of the shaft 15 and the stirring rods 16 are rotatably engaged in the mixing chamber 12. The motor 14 drives the shaft 15 to drive the stirring rods 16 to rotate in the mixing chamber 12, thereby improving the uniformity and efficiency of mixing the perfume raw materials.
