Description

Technical Field

[0001] The present invention relates to the technical field of sterilization of beauty refrigerators, and in particular to a sterilization module and method of a beauty refrigerator, and a beauty refrigerator. Background Art

[0002] Beauty refrigerators are a new type of product used to store skin care products and cosmetics. They are used in homes and dressing rooms. Beauty refrigerators are gradually being used in homes and dressing rooms. As people pay more and more attention to beauty and skin care, the types and quantity of beauty products are also increasing. At present, beauty refrigerators on the market have hardly considered the sterilization of cosmetics, and most of the existing beauty refrigerators lack sterilization functions.

[0003] The existing sterilization method usually adopts ozone sterilization. On the one hand, the ozone concentration is difficult to detect under home conditions. There is a lack of professional detection equipment in the home environment, and it is difficult for users to judge whether the ozone concentration is appropriate. On the other hand, ozone itself has two sides. Excessive ozone concentration will cause harm to human health, such as irritating the respiratory tract and damaging the skin. Too low ozone concentration will not have a sterilization effect. These two situations make it difficult to choose the layout of the sterilization module in the beauty refrigerator. If the sterilization module is not designed properly, it will not only fail to effectively sterilize, but may also cause adverse effects on users due to problems such as ozone leakage. At the same time, when designing a beauty refrigerator, its appearance also needs to be considered. As a product placed in a more conspicuous location such as a home or dressing room, its appearance design is very important, so a sterilization module design that can ensure the control function without affecting the appearance is needed. Therefore, it is urgent to develop a beauty refrigerator with a sterilization function to meet the diverse needs of users.

[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] Embodiment 1 This embodiment provides a sterilization module for a beauty refrigerator. Figure 2 and Figure 3 , the sterilization module comprises: A fan cover 1, and an ion generator 3 and a fan 2 arranged in layers in the fan cover 1; The controller is connected to the ion generator 3 and the fan 2 respectively, and is used to control the sterilization mode of the ion generator 3 and the fan 2.

[0022] See also Figure 2 and Figure 3In the sterilization module 4 of this embodiment, the ion generator 3 is used to generate ozone. Ozone is a strong oxidant with a sterilization function. Its core component is a high-voltage power supply that can generate high voltage. The high voltage is usually between several thousand volts and tens of thousands of volts. The high voltage generated by the high-voltage power supply is released into the air through a discharge needle (also called a corona needle). In this process, electrons are stripped from the discharge needle and enter the surrounding air. When these free electrons meet oxygen molecules in the air, they will be captured by the oxygen molecules to form negatively charged oxygen ions, i.e., negative oxygen ions, i.e., ozone; the fan 2 is used to accelerate the expansion of ozone, so that ozone can diffuse more quickly inside the beauty refrigerator 5, thereby improving the sterilization effect. The controller is used to control the sterilization mode of the ion generator 3 and the fan 2, which greatly improves the intelligence of the present invention, solves the technical problem that most existing beauty refrigerators lack sterilization function, and greatly improves the availability and reliability of the present invention.

[0023] Specifically, the internal space of the fan cover 1 includes adjacent inner accommodating chamber and outer accommodating chamber along the central axis direction; The ion generator 3 is arranged in the inner accommodating chamber, and the fan 2 is arranged in the outer accommodating chamber.

[0024] Furthermore, the fan cover 1 serves as a protective cover and is located in the outermost layer to prevent foreign objects from entering the area where the fan 2 and the ion generator 3 are located. It also serves as an isolation to prevent ozone from leaking into the external environment. The fan 2 and the ion generator 3 are respectively arranged in the inner and outer accommodating chambers of the fan cover 1, so that the ozone generated by the ion generator 3 can be quickly and evenly distributed inside the beauty refrigerator 5 under the action of the fan. At the same time, the existence of the fan cover 1 also ensures safety and stability during use.

[0025] It should be noted here that the present embodiment provides a sterilization module for a beauty refrigerator. The ion generator generates ozone for sterilization, and the fan accelerates the diffusion of ozone. The two work together to improve the sterilization efficiency. The fan cover protects the internal components and prevents ozone leakage, ensuring safe and stable use. This sterilization module solves the problem that most beauty refrigerators have no sterilization function, so that the inside of the refrigerator can be sterilized quickly and evenly, greatly improving the usability and reliability of the beauty refrigerator, and meeting the needs of users for sterilizing beauty products.

[0026] Embodiment 2 See also Figure 3 This embodiment provides a beauty refrigerator, and the beauty refrigerator 5 includes the sterilization module 4 in the first embodiment.

[0027] Specifically, the sterilization module 4 is arranged on one side of the top of the beauty refrigerator 5.

[0028] It should be noted here that the present embodiment provides a beauty refrigerator. By arranging the sterilization module on one side of the top of the beauty refrigerator 5, it can maximize the efficiency of ozone generation and ensure the sterilization function without affecting the appearance and user use. It solves the technical problem that the ozone concentration is difficult to detect under home conditions and there is a lack of professional detection equipment in the home environment, making it difficult for users to judge whether the ozone concentration is appropriate, making it difficult to select the layout of the sterilization module inside the beauty refrigerator. This greatly improves the practicality and reliability of the beauty refrigerator of the present invention.

[0029] Embodiment 3 See also Figure 1-Figure 5 The present embodiment provides a sterilization method for a beauty refrigerator, the method comprising: obtaining the power-on time of the beauty refrigerator 5; according to the power-on time, controlling the sterilization module 4 to work in different sterilization modes, which solves the problem of bacteria breeding during the storage of cosmetics, and most of the existing beauty refrigerators 5 lack a sterilization function. The existing ozone sterilization method has a technical problem that the ozone concentration is difficult to detect under home conditions. Through logical control, the ozone concentration is kept within an effective and safe range without adding an ozone concentration detection device, and the sterilization module 4 is arranged on one side of the top of the beauty refrigerator 5, which can maximize the efficiency of ozone generation without affecting the appearance, thereby greatly improving the intelligence, usability and reliability of the present invention.

[0030] See also Figure 1 In the sterilization method of this embodiment, the method includes: S100, obtaining the power-on time of the beauty refrigerator 5; S200 , controlling the sterilization module 4 to operate in different sterilization modes according to the power-on time.

[0031] In some specific embodiments, the ozone concentration in a certain beauty refrigerator is defined as Y, in ppb. Through experimental measurements, it is found that the ozone concentration Y in the beauty refrigerator can only effectively sterilize when it reaches 100. When the value of Y is greater than 150, it will cause harm to the human body. Therefore, in the absence of ozone detection, the ozone concentration Y inside the beauty refrigerator needs to be kept at around 100.

[0032] Furthermore, common ozone detection methods include: chemical colorimetry, ultraviolet absorption spectroscopy, electrochemical sensor method, chemiluminescence method, laser induced fluorescence method, etc., among which the electrochemical sensor method is more suitable. Its working principle is to measure the ozone concentration by detecting the current change generated by the chemical reaction between ozone and the sensor electrode. It has the following advantages: fast response speed, high sensitivity, and low cost. The electrochemical sensor method can be used to detect ozone for experimental measurements.

[0033] Specifically, controlling the sterilization module 4 to work in different sterilization modes according to the power-on time includes: If the power-on time is longer than the first preset threshold and the beauty refrigerator 5 is in a closed door state, the sterilization mode is entered; In the sterilization mode, the first sterilization mode is executed and then ends after the first preset time, and then the interval time is counted. After the second preset time, the second sterilization mode is executed.

[0034] See also Figure 4 In the sterilization method of the present embodiment, the first preset threshold is preferably set to 24 hours, that is, when the beauty refrigerator 5 is powered on for 24 hours in a closed-door state, the residual ozone inside will all dissipate. This is because the beauty refrigerator 5 is not in a sealed state when the door is powered on, and the fan 2 in the sterilization module 4 is controlled to rotate for five minutes every twenty minutes to accelerate the air circulation. Therefore, regardless of whether the door is open or closed, after a period of time (24 hours), the ozone in the refrigerator can all dissipate. The ozone concentration can be tested by the electrochemical sensor method. Its working principle is to measure the ozone concentration by detecting the current change generated by the chemical reaction between ozone and the sensor electrode. It has a fast response speed and high sensitivity. After a large number of actual tests by the technicians of the present invention, the ozone has all dissipated after 24 hours in a closed-door state. Therefore, when the beauty refrigerator 5 is in a closed-door state, the preset sterilization condition can be reached after the power-on time reaches 24 hours, that is, the first sterilization mode is started, and ozone begins to be generated inside the beauty refrigerator for sterilization, which can further improve the sterilization efficiency and ensure the timeliness and safety of the sterilization inside the refrigerator.

[0035] Furthermore, it is not suitable to perform sterilization operations when the door is open, because the entry of outside air will affect the sterilization effect. Therefore, it helps to save energy when the door is closed, because the sterilization module does not need to work all the time and will only be started when specific conditions are met. At the same time, it can also perform sterilization operations accurately at the right time, which can effectively ensure that the interior of the beauty refrigerator is always in a relatively clean and sterile state.

[0036] See also Figure 4In the sterilization method of this embodiment, the second preset time refers to the time when the beauty refrigerator 5 is in a closed state and the sterilization module is turned off, and the internal ozone concentration is reduced from 100 to 95. The second preset time can be detected by chemical colorimetry, ultraviolet absorption spectroscopy, electrochemical sensor method, chemiluminescence method, laser induced fluorescence method and other methods. That is, when the first sterilization mode is completed, the ozone concentration inside the beauty refrigerator 5 is 100, and the ozone concentration at this time can effectively sterilize. However, after the door is closed for a period of time, the ozone inside the refrigerator will escape to a certain extent. Therefore, when the first sterilization mode is executed after the second preset time, it is necessary to start the second sterilization mode to restore the ozone concentration inside the refrigerator from 95 to about 100. After experimental verification, the second preset time T can be set to 8 minutes, thereby further ensuring the sterilization function inside the beauty refrigerator 5 and preventing bacteria from growing, making the present invention safer and more reliable.

[0037] It should be further explained that when the preset sterilization conditions are not triggered, the sterilization module 4 remains in a closed state. At the same time, when the door of the beauty refrigerator 5 is open, the sterilization module 4 also remains in a closed state.

[0038] Specifically, the first sterilization mode includes: The power of the ion generator 3 in the sterilization module 4 is set to the first preset power, the rotation speed of the fan 2 in the sterilization module 4 is set to the first preset rotation speed, and the execution time of the first sterilization mode is the first preset time.

[0039] In the sterilization method of the present embodiment, in the first sterilization mode, the power of the ion generator 3 and the speed of the fan 2 in the sterilization module 4 are set respectively, so that they operate at high power and high speed. This mode is a process in which the ozone concentration Y inside the beauty refrigerator 5 changes from 0 to 100. High power generally refers to the ion generator 3 working at the rated power. Therefore, in the present embodiment, the first preset power is preferably the rated power of the beauty refrigerator, for example, 42W. In the present embodiment, the first preset speed of the fan 2 is preferably 1200r / min. The first preset duration refers to the first sterilization mode, that is, when the power of the ion generator 3 and the speed of the fan 2 are the first preset power and the first preset speed respectively, the ozone concentration Y inside the beauty refrigerator 5 changes from 0 to 100, and the sterilization module 4 operates for a time t1. The first preset duration can be measured by chemical colorimetry or ultraviolet absorption spectroscopy. Methods such as method, electrochemical sensor method, chemiluminescence method, laser induced fluorescence method, etc., are used. When the power of the ion generator 3 and the speed of the fan 2 are respectively the first preset power and the first preset speed, experimental measurements are carried out to obtain the results. In this embodiment, the experimental measurement shows that t1 is approximately 20 minutes. Therefore, the present invention preferably sets the first preset time length to 20 minutes. The present invention does not further limit the values ​​of the first preset power, the first preset speed, and the second preset time length. As long as it can adapt to the sterilization method of the beauty refrigerator described in the present invention, by setting the first preset power and the first preset speed in the first sterilization mode, as well as the execution time of the first sterilization mode, it can be ensured that the first sterilization mode is started in time after the beauty refrigerator reaches the sterilization conditions, so that the ozone concentration inside the refrigerator is increased to a concentration that can effectively sterilize, thereby further ensuring the safety inside the beauty refrigerator.

[0040] Specifically, the second sterilization mode includes: The power of the ion generator 3 in the sterilization module 4 is set to the second preset power, the speed of the fan 2 in the sterilization module 4 is set to the second preset speed, and the execution time of the second sterilization mode is the third preset time. The second preset power is less than the first preset power, and the second preset speed is less than the first preset speed.

[0041] In the sterilization method of this embodiment, in the second sterilization mode, the power of the ion generator 3 and the speed of the fan 2 in the sterilization module 4 are set respectively, so that they operate at normal power and normal speed. This mode is a process of maintaining the ozone concentration Y inside the beauty refrigerator 5 at about 100. The normal power, that is, the second preset power can be set to 80% of the rated power, that is, in this embodiment, the second preset power of the ion generator 3 is preferably 34W, and the second preset speed of the fan 2 is preferably 800r / min. The third preset time refers to the second sterilization mode, that is, the power of the ion generator 3 and the speed of the fan 2 are respectively the second preset power and the second preset speed. The ozone concentration Y inside the refrigerator 5 is maintained at about 100 (95-100), and the running time of the sterilization module 4. Similarly, the third preset time t2 can be obtained through experiments. In this embodiment, the third preset time t2 is preferably 2 minutes. The present invention does not further limit the values ​​of the second preset power, the second preset speed, and the third preset time. As long as it can adapt to the sterilization method of the beauty refrigerator described in the present invention, by setting the second preset power and the second preset speed in the second sterilization mode, as well as the execution time of the second sterilization mode, the ozone concentration inside the beauty refrigerator is maintained at a concentration that can effectively sterilize, which largely ensures the sterilization effect and improves the usability of the present invention.

[0042] Specifically, the sterilization method further includes: Determine whether the beauty refrigerator 5 is in an open door state during the execution of the first sterilization mode. If so, interrupt the execution of the first sterilization mode. When the running time of the beauty refrigerator 5 after closing the door is greater than the first preset threshold, execute the first sterilization mode again. If not, the first sterilization mode continues to be executed until the first sterilization mode is completed.

[0043] See also Figure 5 In some specific embodiments, if the door is opened, an interrupt signal is sent by the proximity switch to interrupt any execution operation. If the process is interrupted in the first sterilization mode, that is, the door is opened, the sterilization module is restarted, that is, the beauty refrigerator 5 is powered on and runs for 24 hours again. When the beauty refrigerator 5 is in a closed door state, the first sterilization mode is started. This can effectively prevent the beauty refrigerator 5 from failing to reach an effective sterilization concentration due to the door opening during the execution of the first sterilization mode. The door opening state further accelerates the escape of ozone. Therefore, it is necessary to restart the first sterilization mode to ensure that the ozone concentration inside the refrigerator can reach an effective sterilization concentration.

[0044] Specifically, the sterilization method further includes: Determine whether the beauty refrigerator 5 is in an open door state after the first sterilization mode is executed. If so, interrupt the timing of the interval time after the first sterilization mode is finished, and record the door opening time of the beauty refrigerator 5 from opening the door to closing the door again, and determine whether the door opening time is greater than a fourth preset time. If so, automatically execute the first sterilization mode, and the execution time is the first preset time; If not, determining whether the door opening time is greater than a fifth preset time, and determining whether to automatically execute the second sterilization mode according to the determination result; The fourth preset time length is greater than the fifth preset time length.

[0045] See also Figure 5 In the sterilization method of this embodiment, if the sterilization module performs the door opening operation after the first sterilization mode is completed, the recording of the timing time t in the closed door state will be interrupted, and the door opening time tx will be recorded at the same time, and the recording will end after the door is closed again. At this time, it is necessary to judge the door opening time of the beauty refrigerator, so as to determine the degree of ozone concentration in the refrigerator when the door is open. In order to maintain the ozone concentration in the refrigerator at an effective sterilization concentration, it is necessary to determine whether to restart the first sterilization mode or the second sterilization mode according to the statistical door opening time of the refrigerator; In some specific embodiments, see Figure 6 , fitting the curve of the internal ozone concentration Y of the beauty refrigerator 5 with the door open over time, defining Figure 6 Point A is the curvature inflection point. After time tn, the ozone concentration inside the refrigerator reaches point A. After time t0, the ozone concentration inside the refrigerator drops to 0. The first straight line is fitted before point A, and the second straight line is fitted after point A. In fact, the more straight lines are fitted, the more accurately the amount of ozone concentration inside the refrigerator can be grasped. After the door is opened, the ability of the ozone concentration inside the refrigerator to maintain around 100 is more stable. Therefore, the fourth preset time is set to Figure 6 In the t0, the fourth preset time t0 is set to 1h in this embodiment, that is, the ozone concentration inside the refrigerator is reduced to 0 after 1h. Therefore, when the door is closed again, it is necessary to re-execute the first sterilization mode to make the ozone concentration inside the refrigerator reach the effective sterilization concentration. If the door opening time is less than or equal to 1h, the inflection point time is judged to avoid the ozone concentration inside the refrigerator being 0 due to the refrigerator door being opened for too long, and to ensure that when the door is opened for too long, the first sterilization mode can be performed in time to increase the ozone concentration inside the refrigerator to the effective sterilization concentration.

[0046] Specifically, the determining whether the door opening time is greater than a fifth preset time, and determining whether to automatically execute the second sterilization mode according to the determination result, includes: If the door opening time is longer than the fifth preset time, the second sterilization mode is automatically executed, and the execution time of the second sterilization mode is the sixth preset time; In some specific embodiments, see Figure 6 , the fifth preset time length is set to tn. In this embodiment, the fifth preset time length tn is preferably 33 minutes. When the ozone concentration inside the refrigerator decreases to the inflection point, the second sterilization mode is executed to restore the ozone concentration inside the refrigerator to the effective sterilization concentration. At this time, the execution time of the second sterilization mode can be calculated according to the ozone concentration and the time for the sterilization module 4 to execute sterilization. The specific calculation method is as follows: The ozone concentration Y is substantially proportional to the execution time t of the second sterilization mode, which can be expressed as: Y=k v t, Among them, k v Indicates the speed of ozone concentration increase in the refrigerator. Fit the straight line of ozone concentration rising with the execution time of sterilization mode before the inflection point tn. Fit the curve of ozone concentration Y1 changing with time before the inflection point tn with a straight line. The fitting result is: Y1=k a t+b1, Among them, k a is the slope of the fitted line, k a <0, b1 is the constant coefficient of the straight line before fitting tn, it can be concluded that ΔY1=k a *Δt (absolute value); Among them, ΔY1 is the change of ozone concentration within Δt time. Since the time t for executing the second sterilization mode can be expressed as: t=ΔY / kv, Then, in the straight line before the fitting inflection point tn, substitute ΔY1=k a *Δt (absolute value), we can get: t=k a *Δt / kv (absolute value); If the straight line between the inflection points tn-t0 is fitted, the curve of the ozone concentration Y2 changing with time between the inflection points tn-t0 is linearly fitted, and the fitting result is: Y2=k c t+b2, Among them, k c is the slope of the fitted line, k c <0, b2 is the constant coefficient of the straight line between the fitting inflection points tn-t0, it can be concluded that ΔY2=k c *Δt (absolute value); Among them, ΔY2 is the change of ozone concentration within Δt time. Since the time t for executing the second sterilization mode can be expressed as: t=ΔY / kv, Then fit the straight line between the inflection points tn-t0, and substitute ΔY2=k c *Δt (absolute value), we can get: t=k c *Δt / kv (absolute value); Therefore, according to the above calculation process, when the door opening time tx is less than or equal to t0, the inflection point time is judged. If the door opening time tx is greater than tn, the time t3 for executing the second sterilization mode at this time can be calculated, that is, the sixth preset time, which is specifically expressed as follows: t3=K2*(tx-tn)+K1*tn; Where K1=k a * / kv (absolute value), K2=k c * / kv (absolute value).

[0047] It is understandable that when the refrigerator door is open for 33 minutes, that is, Figure 6 At tn in the figure, the second sterilization mode is executed, and the execution time is t3, so that the ozone concentration inside the refrigerator is maintained at a concentration that is effective for sterilization, which greatly improves the sterilization effectiveness and safety of the present invention.

[0048] If the door opening time is less than the fifth preset time, determine whether the door opening time is greater than the seventh preset time, and if so, automatically execute the second sterilization mode, and the execution time of the second sterilization mode is the eighth preset time, the sixth preset time is greater than the eighth preset time, and the fifth preset time is greater than the seventh preset time; If not, the second sterilization mode is not executed.

[0049] See also Figure 5 In some specific embodiments, if the refrigerator door is opened for a short time, that is, the door opening time is less than the fifth preset time and greater than the seventh preset time, where the seventh preset time ty is less than or equal to the fifth preset time, the ozone concentration in the refrigerator is reduced, but the reduced concentration is small. In this embodiment, the seventh preset time ty is set to 17 minutes, that is, when the refrigerator door is opened for 17 minutes, the second sterilization mode is executed, and the execution time of the eighth preset time t4 is less than the sixth preset time t3. The calculation of t4 is the same as the calculation process of t3 above, and it can be obtained that: t4=K3*tx, where K3=k d * / kv (absolute value), where k dIt represents the slope of the fitting line when the door opening time tx is less than the fifth preset time and greater than the seventh preset time. When the door opening time is less than the seventh preset time ty, that is, the door opening time is extremely short, the impact on the ozone concentration in the refrigerator can be ignored. At this time, the door continues to record the closed time t and executes the closed state logic. The above judgment on the seventh preset time effectively avoids the energy waste caused by the long time required to execute the sterilization module when the door opening time is too short, while ensuring that the ozone concentration inside the refrigerator is maintained within the effective concentration range.

[0050] See also Figure 5 In some specific embodiments, in order to avoid the ozone concentration inside the refrigerator being too high to cause harm to the human body when the sterilization mode is executed, a control logic can be added: when the execution time of the first sterilization mode or the second sterilization mode is greater than the ninth preset time tk, the execution operation of the sterilization mode is interrupted, and the sterilization mode is restarted after 24 hours. In this embodiment, the ninth preset time tk is set to 20 minutes, that is, when the execution time of the first sterilization mode or the second sterilization mode is greater than 20 minutes, the execution operation of the sterilization mode is interrupted, and the sterilization mode is restarted after 24 hours. The above setting can further ensure the safety of the sterilization mode in the present invention.

[0051] It should be noted here that the present embodiment provides a sterilization method for a beauty refrigerator, which uses ozone sterilization through a sterilization module inside the beauty refrigerator, sets a first sterilization mode and a second sterilization mode, and obtains the power-on time of the beauty refrigerator; according to the power-on time, the sterilization module is controlled to work in different sterilization modes, thereby solving the problem of bacteria breeding during the storage of cosmetics, and the technical problem that most of the existing beauty refrigerators lack a sterilization function, and that the ozone concentration of the existing ozone sterilization method is difficult to detect under home conditions.
