Description

Technical Field

[0001] This utility model relates to the field of alcohol purification technology, specifically providing an ultrasonic alcohol purification device with lower noise. Background Technology

[0002] Alcoholic beverages (or simply alcohol) refer to ethanol-containing drinks made from fermented starchy or sugary substances such as grains and fruits. They have a rich history and cultural significance, and moderate consumption can relax the mind and body and relieve stress. There are many types of alcoholic beverages, which can generally be divided into different categories such as baijiu (Chinese white liquor), beer, wine (red wine), and huangjiu (yellow wine) based on different production processes.

[0003] A wine purifier is a device used to purify wine. It typically removes impurities and off-flavors through filtration, adsorption, and ion exchange, resulting in a purer, fresher wine with a smoother, more rounded taste, and extended shelf life. Wine purifiers equipped with ultrasonic transducers can break down large molecular clusters in the wine into smaller ones, accelerating esterification, promoting the combination of ethanol and water, altering the wine's taste and quality, removing impurities and off-flavors, improving purity and flavor, and accelerating the aging process, making the wine more mellow and aromatic.

[0004] To facilitate the commercial application of ultrasonic wine purifiers, an ultrasonic wine purifier with an inner tank was designed. Several ultrasonic transducers are installed on one side of the inner tank. In use, liquid is filled into the inner tank, and the wine is placed in a wine container (such as a wine bottle). The wine container is then placed in the liquid. The ultrasonic transducers are activated, and the ultrasonic waves generated by the transducers are transmitted through the liquid to the wine in the wine container, achieving the purpose of treating the wine with ultrasound. During this process, the liquid remains stationary, resulting in more efficient transmission of ultrasonic waves. However, preliminary trials revealed that the ultrasonic wine purifier generates significant noise during the ultrasonic treatment process, leading to a poor user experience and hindering large-scale commercial promotion and application in restaurants, hotels, and other similar settings. This issue urgently needs to be addressed. Summary of the Invention

[0005] The first aspect of this utility model addresses the problem of further reducing the noise of ultrasonic wine purifiers and improving user experience. It provides a novel ultrasonic wine purifying device that effectively reduces noise during operation, making the device quieter and improving user experience, thus better meeting market demands. The main concept is as follows:

[0006] An ultrasonic wine purification device with lower noise includes a housing, an ultrasonic transducer, and an active noise reduction module. The housing contains an inner tank for containing liquid, and the ultrasonic transducer is positioned on the outside of the inner tank, corresponding to the inside of the inner tank.

[0007] The active noise reduction module is used to agitate the liquid in the inner tank, dispersing the cavitation molecules generated during the operation of the ultrasonic transducer. In this solution, by configuring an inner tank to hold the liquid, the beverage container can be placed in the liquid within the inner tank during actual use. This allows the ultrasonic waves generated by the transducer to be transmitted efficiently and with low loss to the beverage in the container, thus facilitating better ultrasonic processing results. The active noise reduction module agitates the liquid in the inner tank, preventing it from remaining stagnant and instead creating a continuous flow. This constant agitation disperses the cavitation molecules generated during the operation of the ultrasonic transducer, effectively reducing the amount of cavitation molecules near the transducer. This prevents cavitation molecules from accumulating near the transducer, thus reducing noise caused by cavitation accumulating and further reducing noise during processing. This results in quieter operation, improving user experience and meeting market demands, making this equipment suitable for large-scale commercial promotion and application in restaurants, hotels, and other similar settings.

[0008] To address the issue of effectively disturbing the liquid within the inner tank and preventing excessive noise caused by the aggregation of cavitation molecules, some solutions include a circulation pump in the active noise reduction module. The inlet and outlet of the circulation pump are connected to the inner tank, and the pump drives the circulation of the liquid within the tank. In this solution, by configuring a circulation pump and using it to drive the circulation of the liquid within the inner tank, the liquid is kept in a continuous flow rather than a static state. This disperses the cavitation molecules generated during the operation of the ultrasonic transducer, effectively reducing noise.

[0009] To better agitate the liquid inside the inner tank, the active noise reduction module further includes an inlet for inputting liquid into the inner tank and an outlet for outputting liquid from the inner tank. The inlet and outlet are connected to the inner tank, and the circulation pump is connected to both the inlet and outlet, with the inlet positioned higher than the outlet. This allows the liquid to fall into the inner tank from a higher position, agitating the liquid not only using the circulation pump but also utilizing its own gravity, thus achieving a better agitation effect and effectively reducing noise.

[0010] To address the issue of effectively disturbing the liquid within the inner tank and preventing excessive noise caused by the aggregation of cavitation molecules, some solutions include an active noise reduction module that incorporates a stirrer. This stirrer keeps the liquid in the inner tank constantly flowing, preventing it from remaining stagnant. This disperses the cavitation molecules generated during the operation of the ultrasonic transducer, effectively reducing noise.

[0011] Preferably, the agitator includes a motor and a stirring paddle disposed in the inner tank. The motor is connected to the stirring paddle for driving the stirring paddle to rotate, thereby agitating the liquid and reducing noise.

[0012] Furthermore, the device also includes a controller, which is electrically connected to both the ultrasonic transducer and the active noise reduction module. This allows for precise control of the ultrasonic transducer and the active noise reduction module, making the device easier to use.

[0013] In some designs, the ultrasonic transducer is positioned on the outer surface of the inner liner. This not only results in a simple structure and easy assembly, but also allows the ultrasonic waves generated by the transducer to be transmitted through the inner liner to the liquid inside, and then act on the beverage in the beverage container via the liquid.

[0014] Preferably, the inner liner is square in shape. This facilitates both the placement and removal of beverage containers and the assembly of ultrasonic transducers.

[0015] The second aspect of this invention addresses the problem of improving processing effect and efficiency. Specifically, it includes two sets of ultrasonic transducers, each set comprising at least one ultrasonic transducer, with the two sets having different vibration frequencies. In this solution, by configuring two sets of ultrasonic transducers with different vibration frequencies, it not only becomes applicable to different types of alcoholic beverages, improving versatility, but also allows for alternating operation of the two transducers during use. This achieves better processing results and quickly excites cyanide in the alcoholic beverage into gas, thereby rapidly and effectively reducing the cyanide content, mitigating the harmful effects of cyanide, reducing the toxicity of the alcoholic beverage, and improving its safety.

[0016] To achieve better processing and faster reduction of cyanide content, one set of ultrasonic transducers operates at a frequency of 28 kHz, while the other set operates at a frequency of 40 kHz. The combination of these two frequencies allows for rapid reduction of cyanide content in the beverage and achieves better processing results.

[0017] To further reduce the noise of this device, a lid is also included. The housing has an opening for taking out and putting in beverage containers, and the inner liner is connected to the opening. The lid is used to open or close the opening. Not only can beverage containers be taken out through the opening for greater convenience, but the lid also protects the inner liner and the beverage containers inside. Furthermore, it covers the beverage containers during operation, effectively preventing noise from the housing from escaping, thus further reducing the noise of the device.

[0018] The third aspect of this utility model addresses the problem of further reducing the noise of an ultrasonic wine purifier. Specifically, a sound-insulating layer is provided on the inner surface of the housing, and / or a sound-insulating layer is provided on the outer surface of the inner liner, and / or a sound-insulating layer is provided on the inner surface of the lid. This utilizes the sound-insulating layer to isolate internal noise, effectively preventing noise from being transmitted outside the housing, thereby achieving sound insulation and noise reduction, making the device quieter.

[0019] Compared with existing technologies, the ultrasonic wine purification device provided by this utility model has lower noise, which can effectively reduce noise during operation, making the device quieter and improving the user experience. It is more in line with market demand and is conducive to the large-scale commercial promotion and application of this device in restaurants, hotels and other places. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 2 and Figure 3 This embodiment provides an ultrasonic wine purification device, including a housing 1, an inner liner 12, an ultrasonic transducer 3, and an active noise reduction module, wherein...

[0034] The shape of the housing 1 can be determined according to actual needs. In this embodiment, the housing 1 can be square, such as... Figure 2 and Figure 3 As shown, in practice, the shell 1 can also be a common shape such as a cylinder.

[0035] In this embodiment, the shell 1 has a hollow structure, resulting in an internal cavity. The inner liner 12 is disposed within the shell 1, and the shell 1 supports the inner liner 12. The upper end of the inner liner 12 is open to accommodate liquids and also to accommodate beverage containers (such as wine bottles, flasks, and jars). Accordingly, the shell 1 is constructed with an opening 11 for taking out and placing beverage containers, such as... Figure 2 and Figure 3 As shown, the inner liner 12 is connected to the opening 11, and the opening at the upper end of the inner liner 12 can be located below the opening 11, such as... Figure 3 and Figure 4 As shown, it can also be located inside the access port 11, allowing the user to retrieve beverage containers from the inner liner 12 through the access port 11. In a more complete design, the device is also equipped with a lid 2, such as... Figures 2-4 As shown, the lid 2 is used to open or close the access port 11. The lid 2 serves to protect the inner liner 12 and the beverage container inside it. In some situations, it can also cover the beverage container, effectively preventing noise transmission from the housing 1, thus further reducing the noise of the device. In implementation, the lid 2 can be rotatably connected to the housing 1 using an existing hinged structure. Alternatively, the lid 2 can be attached to the housing 1 using an existing snap-fit ​​structure, magnetic structure, etc., for easy opening and closing. The lid 2 is equipped with a handle for convenient operation.

[0036] In implementation, the shape of the inner liner 12 can be determined according to actual needs. For example, in this embodiment, the inner liner 12 is constructed as a square, such as... Figure 3 and Figure 4 As shown, this makes it easier to pick up and put down seeds. After the inner liner 12 is installed on the shell 1, the inner liner 12 can be used to divide the internal cavity of the shell 1 into an inner cavity 13 and an outer cavity 14. The space inside the inner liner 12 is the inner cavity 13, and the space outside the inner liner 12 is the outer cavity 14. In implementation, the circuit boards, controllers, power modules and other components required by this device can be set in the outer cavity 14. These will not be listed here.

[0037] In this embodiment, the ultrasonic transducer 3 is disposed in the outer cavity 14, such as... Figure 4 As shown, the ultrasonic transducer 3 is disposed on the outer side of the inner liner 12 and corresponds to the interior of the inner liner 12; that is, the emitting end of the ultrasonic transducer 3 corresponds to the inner cavity 13 of the inner liner 12. In implementation, the ultrasonic transducer 3 can be disposed on the outer surface of the inner liner 12, such as... Figure 4 As shown, for example, the ultrasonic transducer 3 can be directly attached to the outer surface of the inner liner 12, or it can be fixed to a bracket connected to the inner liner 12 or the shell 1, with the transmitting end of the ultrasonic transducer 3 contacting (or abutting) the outer surface of the inner liner 12. In use, the ultrasonic waves generated by the ultrasonic transducer 3 can be transmitted through the side wall of the inner liner 12 to the interior of the inner liner 12, and can also be transmitted through the liquid in the inner liner 12 to the beverage container. For example, in this embodiment, the ultrasonic transducer 3 is disposed on the side of the inner liner 12, such as... Figure 4 As shown, this is to better apply ultrasound to the beverage inside the container.

[0038] In a more complete solution, the device also includes a controller, which is located in the outer cavity 14 and electrically connected to the ultrasonic transducer 3, so as to accurately control the start and stop, working time, etc. of the ultrasonic transducer 3, making it easier to use the device.

[0039] When using this device, the inner liner 12 is filled with liquid. The user first places the beverage container into the liquid in the inner liner 12, ensuring that the liquid covers at least the bottom of the beverage container. The beverage container is filled with beverage. Then, the user can activate the ultrasonic transducer 3. The ultrasonic waves generated by the ultrasonic transducer 3 act on the beverage in the beverage container through the liquid, thereby purifying the beverage and improving its taste.

[0040] However, in the initial practical trials, it was found that during the operation of the ultrasonic transducer 3, if the liquid inside the inner tank 12 was in a stagnant state, the noise during the process was greater. Conversely, if the liquid inside the inner tank 12 was allowed to flow, the noise during the process was significantly reduced, especially eliminating some sharper noises. Based on this, analysis revealed that the main reason for this phenomenon is that the ultrasonic waves generated by the ultrasonic transducer 3 produce a cavitation effect in the liquid as they pass through it. The cavitation molecules 5 generated by this cavitation effect accumulate near the ultrasonic transducer 3, such as... Figure 1 As shown, the aggregated cavitation molecules 5 significantly increase the noise during the processing. Therefore, to effectively reduce the noise of this device, the ultrasonic wine purifier provided in this embodiment is also equipped with the aforementioned active noise reduction module. The active noise reduction module is mainly used to disturb the liquid in the inner tank 12 during the operation of the ultrasonic transducer 3, so that the cavitation molecules 5 generated during the operation of the ultrasonic transducer 3 are dispersed in the liquid. That is, by using the active noise reduction module to disturb the liquid in the inner tank 12, the liquid in the inner tank 12 is not in a static state, but in a continuously flowing state. Through continuous disturbance, the cavitation molecules 5 generated during the operation of the ultrasonic transducer 3 can be dispersed in the liquid, thereby effectively reducing the amount of cavitation molecules 5 near the ultrasonic transducer 3. This prevents the cavitation molecules 5 from all accumulating near the ultrasonic transducer 3, thereby effectively reducing the noise caused by the aggregation of cavitation molecules 5, achieving the purpose of further reducing the noise during the processing, making the device quieter to use, thus effectively improving the user experience, better meeting market demands, and facilitating the large-scale commercial promotion and application of this device in restaurants, hotels, and other places.

[0041] To utilize the active noise reduction module to agitate the liquid in the inner tank 12, the active noise reduction module can be implemented in various ways. For example, in one implementation, the active noise reduction module may include a circulation pump 41, such as... Figure 3As shown, the inlet and outlet of the circulation pump 41 are respectively connected to the inner liner 12. The circulation pump 41 drives the liquid inside the inner liner 12 to circulate, ensuring that the liquid inside the inner liner 12 is not static but constantly flowing. This disperses the cavitation molecules 5 generated during the operation of the ultrasonic transducer 3, effectively reducing noise. In a specific implementation, the inlet and outlet of the circulation pump 41 can be connected to the inner liner 12 via pipes 44 to form a circulation loop, allowing the liquid to circulate. In implementation, the active noise reduction module also includes an inlet 43 for inputting liquid into the inner liner 12 and an outlet 42 for outputting liquid from the inner liner 12. The inlet 43 and outlet 42 are respectively connected to the inner liner 12, and the circulation pump 41 is connected to both the inlet 43 and outlet 42. In implementation, the outlet 42 can be constructed within the inner liner 12 or as a drain connector connected to the inner liner 12. Correspondingly, in implementation, the inlet 43 can be constructed within the inner liner 12 or not. For example, the inlet 43 can be the outlet of a pipe 44, the outlet of which corresponds to the inner liner 12. The pipe 44 is connected to a circulation pump 41, which also enables liquid circulation. To better agitate the liquid within the inner liner 12, in implementation, the inlet 43 can be higher than the outlet 42, such as... Figure 3 As shown, this allows the liquid to fall into the inner liner 12 from a higher position. This not only utilizes the circulation pump 41 to agitate the liquid but also leverages the liquid's own gravity, achieving a better agitation effect and effectively reducing noise. In a more specific embodiment, when the inner liner 12 is square, its four sidewalls are designated as a first sidewall 121, a second sidewall 122, a third sidewall 123, and a fourth sidewall 124. The first sidewall 121 faces the third sidewall 123, and the second sidewall 122 faces the fourth sidewall 124. Figures 3-5 As shown, the ultrasonic transducer 3 can be disposed on the first side wall 121. In some embodiments, the inlet 43 and outlet 42 can be disposed on the second side wall 122 and the fourth side wall 124, respectively. Figure 3 As shown, the inlet 43 and outlet 42 can also be set on the first side wall 121 and the third side wall 123 respectively, which is conducive to achieving better noise reduction effect. Examples will not be given here.

[0042] For example, in another embodiment, the active noise reduction module may further include a stirrer, such as... Figure 6As shown, the agitator is used to stir the liquid in the inner liner 12, ensuring that the liquid is not stagnant but continuously flowing. This disperses the cavitation molecules 5 generated during the operation of the ultrasonic transducer 3, effectively reducing noise. As an example, the agitator may include a motor 45 and a stirring paddle 47 disposed within the inner liner 12. The motor 45 is driven by the stirring paddle 47 to rotate, thus stirring the liquid in the inner liner 12. Preferably, the motor 45 can be installed in the outer cavity 14 and fixed to the outer surface of the inner liner 12. The motor 45 is connected to the stirring paddle 47 via a drive shaft 46 extending into the inner liner 12, thus positioning the stirring paddle 47 within the inner liner 12. In implementation, the drive shaft 46 can be arranged vertically. In this case, the stirrer can be positioned at the bottom of the inner liner 12 to stir the liquid within it from the bottom. In a more refined embodiment, a horizontally arranged partition with several mesh openings can be installed at the bottom of the inner liner 12. The upper part of the partition can support the placed beverage container, and the stirrer can be positioned below the partition so that the placed beverage container does not interfere with the stirrer below. Furthermore, in implementation, the drive shaft 46 can be arranged horizontally, for example, as... Figure 6 As shown, the stirrer can preferably be located at the third side wall 123, with the drive shaft 46 perpendicular to the third side wall 123. Of course, the stirrer can also be located at the second side wall 122 and the fourth side wall 124. In implementation, the number of stirrers can be one, two, or more, in order to achieve a better disturbance effect.

[0043] It is understandable that, during implementation, the active noise reduction module can also be configured with the circulation pump 41 and the agitator at the same time, so as to stir the liquid in the inner tank 12 while driving the liquid circulation flow, which is conducive to the cavitation molecules 5 being more evenly dispersed in the liquid, thereby reducing the noise caused by the aggregation of cavitation molecules 5 and making the whole device quieter.

[0044] In addition, the active noise cancellation module can also be implemented in other ways. For example, the active noise cancellation module may include an air pump and an air tube. The air pump is connected to the inner liner 12 through the air tube, and the air pump delivers gas into the inner liner 12, thereby achieving noise reduction by disturbing the liquid in the inner liner 12. Other implementations of the active noise cancellation module will not be described in detail here.

[0045] In practice, the controller is also electrically connected to the active noise cancellation module so that the controller can precisely control the start and stop of the active noise cancellation module. For example, during use, the controller can be used to control the active noise cancellation module and the ultrasonic transducer 3 to start synchronously, making it easier to use the device.

[0046] To further reduce the noise of the ultrasonic wine purifier, in a more refined solution, a sound-insulating layer is provided on the inner surface of the housing 1, and / or, a sound-insulating layer can also be provided on the outer surface of the inner liner 12, and / or, a sound-insulating layer can also be provided on the inner surface of the lid 2. This allows the sound-insulating layer to isolate internal noise and effectively prevent noise from being transmitted outside the housing 1, thereby achieving sound insulation and noise reduction, making the device quieter. In implementation, the sound-insulating layer can be implemented using existing technology; for example, in this embodiment, the sound-insulating layer is made of sound-insulating cotton.

[0047] Example 2

[0048] To address the issues of improving processing effectiveness and efficiency, the main difference between this embodiment 2 and embodiment 1 is that the ultrasonic wine purification device provided in this embodiment includes two sets of ultrasonic transducers 3, each set of ultrasonic transducers 3 including at least one ultrasonic transducer 3, such as... Figures 4-6 As shown, the two sets of ultrasonic transducers 3 have different vibration frequencies. In this embodiment, by configuring two sets of ultrasonic transducers 3 with different vibration frequencies, it can not only be applied to different types of alcoholic beverages, improving versatility, but also control the two ultrasonic transducers 3 to operate alternately during use. This can achieve better processing results and quickly excite cyanide in the alcoholic beverage into gas, thereby rapidly and effectively reducing the cyanide content in the alcoholic beverage, reducing the harm of cyanide, reducing the toxicity of the alcoholic beverage, and improving the safety of the alcoholic beverage.

[0049] In implementation, the vibration frequency of each set of ultrasonic transducers 3 can be matched according to actual needs. Through preliminary experiments, to achieve better treatment and rapid reduction of cyanide content, in a more preferred embodiment, the vibration frequency of one set of ultrasonic transducers 3 is 28KHz. Figures 4-6 As shown, this group of ultrasonic transducers 3 includes two ultrasonic transducers 3 with a vibration frequency of 28KHz, which can be referred to as the first ultrasonic transducer 31. The other group of ultrasonic transducers 3 has a vibration frequency of 40KHz, as shown in the figure. Figures 4-6 As shown, this set of ultrasonic transducers 3 includes two ultrasonic transducers 3 with a vibration frequency of 40KHz, which can be referred to as the second ultrasonic transducer 32. Both sets of ultrasonic transducers 3 can have a power of 60W. Through the combination of these two frequencies, the cyanide content in the beverage can be rapidly reduced, achieving a better treatment effect. Specifically, in practical use, this configuration can reduce the cyanide content in the beverage to below 0.01mg / L within 3-5 minutes, with a very significant effect. Furthermore, it also makes the beverage taste smoother and more rounded.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
