Description

Technical Field

[0001] The present invention relates to the technical field of household cleaning appliances, in particular to an ultra-fine water mist spraying cleaning appliance. Background Art

[0002] Carbonated springs are essentially water dissolved with carbon dioxide. Due to their slightly acidic nature, they not only have cardiovascular benefits but can also improve scalp problems. They are commonly used in skin care and hair cleansing applications. For more information, refer to the relevant information in Announcement No. CN219231038U. For example, a household carbonated spring cleanser uses pressure to spray carbonated springs in the form of nano-water mist, which massages and cleanses pores.

[0003] It should also be noted that the solubility of carbon dioxide in water is directly related to pressure and temperature. The higher the pressure, the higher the solubility. However, as the temperature rises, carbon dioxide will precipitate and reduce the solubility. The carbonated spring used for skin care / head cleansing must first be heated to a suitable temperature. In order to ensure the amount of carbon dioxide dissolved in the carbonated spring, the internal environmental pressure of the structure such as the water storage tank needs to be further increased. However, in the process of releasing the carbonated spring, the internal environmental pressure of the water storage tank is greatly reduced. On the basis of reduced pressure / constant temperature, carbon dioxide precipitates and affects the pH value of the carbonated spring. Due to the change in the pH value of the carbonated spring, the effect of the carbonated spring is negligible. This application proposes a solution to this problem. Summary of the Invention

[0004] The present invention aims to provide an ultra-fine water mist spray washer for household carbonated springs. When carbonated springs are released in the form of nano-water mist, at a constant temperature, the internal pressure environment of the structure storing the carbonated springs changes, causing carbon dioxide to precipitate and affect the pH value of the carbonated springs, resulting in minimal effect of the carbonated springs.

[0005] The object of the present invention can be achieved by the following technical solution: an ultra-fine water mist spray washer, comprising a housing, a control assembly, an air storage tank, and a micro air pump assembly, wherein the control assembly is disposed inside the housing, and a water circulation assembly corresponding to the air storage tank is disposed inside the housing;

[0006] The water circulation assembly includes a water storage tank, a transfer tank and an auxiliary tank. The lower ends of the water storage tank and the auxiliary tank are respectively equipped with a water inlet and a water outlet that penetrate to the outside of the shell. The top end of the gas storage tank is provided with a two-way joint pipe corresponding to the water storage tank and the transfer tank. A partition block is installed at the bottom end of the water storage tank, and a gas-liquid separation piston is slidably installed in the internal position of the transfer tank.

[0007] It is further configured as follows: the micro air pump assembly is installed at a lower side position of the corresponding air storage tank, and the micro air pump assembly is used to increase the pressure inside the air storage tank.

[0008] It is further configured as follows: the double-way joint pipe is composed of a first-stage pipe and a second-stage pipe, the first-stage pipe and the second-stage pipe are respectively installed on the top positions of the water storage tank and the transfer tank, and the air storage tank is connected to the inside of the water storage tank and the transfer tank through the double-way joint pipe.

[0009] It is further configured that: an on-off switch is provided on the first-stage tube and the second-stage tube.

[0010] It is further configured as follows: a liquid blocking piston and a pressure cone cap are respectively provided at the upper and lower positions of the separation block, a liquid guide column is connected between the liquid blocking piston and the pressure cone cap, and the liquid guide column and the separation block are slidably connected.

[0011] It is further configured as follows: a liquid outlet is opened at the upper end position of the liquid-guiding column corresponding to the lower side of the liquid-blocking piston, and the pressure cone cap is in sliding connection with the inner wall of the water storage tank.

[0012] It is further configured as follows: a liquid replenishing tank is provided at the internal position of the lower side of the pressure cone cap corresponding to the water storage tank, the diameter of the middle position of the gas-liquid separation piston is smaller than the inner diameter of the transfer tank, and the interior of the transfer tank is provided with a gas transfer tank, a liquid outlet tank and a liquid transfer tank arranged from top to bottom through the gas-liquid separation piston, and the liquid outlet tank is arranged at the middle position corresponding to the gas-liquid separation piston.

[0013] It is further configured as follows: a through pipe is connected between the liquid replenishment tank and the liquid transfer tank, a two-way pipe is connected between the internal position of the water storage tank corresponding to the upper side of the partition block and the gas transfer tank or the liquid outlet tank, and a three-way pipe corresponding to the transfer tank is installed on the auxiliary tank, and the three-way pipe is connected to the inside of the gas transfer tank or the liquid outlet tank.

[0014] It is further configured that: the intersection positions of the three-way pipe, the two-way pipe and the transfer tank are not on the same horizontal plane.

[0015] The present invention has the following beneficial effects:

[0016] Regarding the release process of carbonated spring application, the transfer tank is the key structure in the carbonated spring circulation process, the water storage tank is used for the storage and preparation of carbonated spring, and the transfer tank is used as an auxiliary structure in the carbonated spring release process. Its essence is to maintain the pressure grouting inside the water storage tank through the transfer tank. Specifically, the liquid transfer tank in the transfer tank and the liquid replenishment tank in the water storage tank are used as the basis. The overall structure only takes the gas pressure inside the water storage tank as the only consideration. However, during the carbonated spring release process, the pressure environment inside the water storage tank is "transferred" through the two-way conversion process of gas and liquid volume.

The movement process of the gas-liquid separation piston is directly related to the gas pressure of carbon dioxide and the liquid pressure of pure water. The key content is to establish a dual-pressure difference model for the release process of carbonated springs. It is based on two pressures and the water replenishment rate of pure water is the key. By limiting the "activity" and "activity mode" of the gas-liquid separation piston, the pressure environment inside the water storage tank is further "spread out". It is mainly used to maintain the pressure environment inside the water storage tank. On the one hand, it reduces the amount of carbon dioxide precipitation in the carbonated spring due to temperature, and also plays a role in stabilizing the release pressure of the carbonated spring.

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: For household carbonated spring spray cleaners, when releasing carbonated spring in the form of nano-water mist, at a constant temperature, the internal pressure environment of the structure storing the carbonated spring changes, causing carbon dioxide to precipitate and affect the pH value of the carbonated spring, resulting in minimal effect of the carbonated spring. The following technical solution is proposed:

[0028] Reference Figures 1 to 6 In this embodiment, an ultra-fine water mist spray washer includes a housing 1, a control assembly 6, an air storage tank 7, and a micro air pump assembly 2. The control assembly 6 is disposed inside the housing 1, and a water circulation assembly corresponding to the air storage tank 7 is disposed inside the housing 1.

[0029] The water circulation component includes a water storage tank 3, a transfer tank 4 and an auxiliary tank 5. The lower ends of the water storage tank 3 and the auxiliary tank 5 are respectively equipped with a water inlet and a water outlet that penetrate into the outside of the shell 1. The top position of the air storage tank 7 is provided with a two-way joint pipe 8 corresponding to the water storage tank 3 and the transfer tank 4. A partition block 9 is installed at the bottom end of the water storage tank 3. A gas-liquid separation piston 10 is slidably installed in the internal position of the transfer tank 4. The micro air pump assembly 2 is installed at the lower side position corresponding to the air storage tank 7, and the micro air pump assembly 2 is used to pressurize the inside of the air storage tank 7. The two-way joint pipe 8 is composed of a first-order pipe and a second-order pipe. The first-order pipe and the second-order pipe are respectively installed at the top positions of the water storage tank 3 and the transfer tank 4. The air storage tank 7 is connected with the inside of the water storage tank 3 and the transfer tank 4 through the two-way joint pipe 8. The first-order pipe and the second-order pipe are provided with an opening and closing switch.

[0030] Basic Principle: A brief explanation of carbonated spring is that its essence is based on a high-pressure environment, which "forces" carbon dioxide to dissolve in water to form carbonated bubble water. Taking the gas tank 7, micro air pump assembly 2 and water tank 3 in the present invention as an example, first, an appropriate amount of pure water is injected into the water tank 3, and then the micro air pump assembly 2 continuously pressurizes the inside of the gas tank 7. The inside of the gas tank 7 serves as a storage structure for carbon dioxide. Therefore, under the pressurizing effect of the micro air pump assembly 2, when carbon dioxide is filled into the water tank 3, the inside of the water tank 3 is also continuously pressurized. It should be added here that the ultra-fine water mist spray washer proposed by the present invention is mainly used in head care work. For this purpose, the pure water in the water tank 3 needs to be heated to a suitable temperature, for example, 30°C. It can be understood that the inside of the water tank 3 mainly serves as a preparation structure and storage structure for carbonated spring.

[0031] During subsequent use, a nozzle can be connected to the water outlet of the auxiliary tank 5, and the carbonated spring stored in the water storage tank 3 is sprayed out through the nozzle under a high-pressure environment. It should be briefly explained that the nozzle structure can be further arranged to ensure that the carbonated spring sprays nano-spray based on high-pressure conditions, which mainly has the effect of cleaning and local massage on the head skin. This part will not be explained in detail. The key content of the present invention lies in the water circulation process of carbonated spring and pure water.

[0032] Example 2: Supplementary explanation of the water circulation process of the water circulation component in Example 1:

[0033] The upper and lower positions of the partition block 9 are respectively provided with a liquid blocking piston 11 and a pressure cone cap 12. A liquid guiding column is connected between the liquid blocking piston 11 and the pressure cone cap 12. The liquid guiding column and the partition block 9 are in sliding connection. A liquid outlet is provided at the upper end position of the liquid guiding column corresponding to the lower side of the liquid blocking piston 11. The pressure cone cap 12 is in sliding connection with the inner wall of the water storage tank 3. A liquid replenishing tank is provided at the internal position of the water storage tank 3 corresponding to the lower side of the pressure cone cap 12. The diameter of the middle section of the gas-liquid separation piston 10 is smaller than the inner diameter of the transfer tank 4. The interior of the transfer tank 4 is connected by a gas-liquid separation piston 10 is provided with a gas transfer bin 402, a liquid outlet bin 403 and a liquid transfer bin 401 arranged from top to bottom. The liquid outlet bin 403 is arranged at the middle position corresponding to the gas-liquid separation piston 10. A through pipe is connected between the liquid replenishment bin and the liquid transfer bin 401. A two-way pipe is connected between the internal position of the water storage tank 3 corresponding to the upper side of the partition block 9 and the gas transfer bin 402 or the liquid outlet bin 403. A three-way pipe corresponding to the transfer tank 4 is installed on the assisting tank 5. The three-way pipe is connected to the inside of the gas transfer bin 402 or the liquid outlet bin 403. The intersection of the three-way pipe, the two-way pipe and the transfer tank 4 is not on the same horizontal plane.

[0034] Solution description: Because the solubility of carbon dioxide in water is directly related to temperature and pressure, the higher the pressure, the higher the solubility of carbon dioxide in water. However, the higher the temperature, the carbon dioxide will also precipitate from the water. The following explanation is provided:

[0035] S1: After the water storage tank 3 is filled with an appropriate amount of pure water, if the internal volume of the water storage tank 3 is V, the replenishment amount of pure inlet water is 2 / 3*V. Since the interior of the gas storage tank 7 is connected to the interior of the water storage tank 3, carbon dioxide is filled into the water storage tank 3. Since the set temperature of the pure inlet water is at a constant state, then only considering the correlation between the pressure condition and the solubility of carbon dioxide, after part of the carbon dioxide dissolves in the water to form carbonated spring, the carbon dioxide will not continue to dissolve in the water, so that the pressure inside the gas storage tank 7 and the water storage tank 3 is at a constant state. However, after the carbonated spring in the water storage tank 3 is discharged, its internal pressure environment is directly reduced, which will also cause the problem of carbon dioxide precipitation. If the internal pressure environment of the water storage tank 3 is simultaneously increased, the spray pressure of the carbonated spring will be too high. This part is the basic content to be solved by the present invention;

[0036] S2: Figure 5 For example, when a fixed amount of carbonated spring is stored in the water tank 3, a stable pressure environment is maintained in the gas tank 7 and the water tank 3, and Figure 6 To illustrate, the upper blocking piston 11 withstands the downward pressure from the carbonated spring and blocks the partition block 9. During this process, the on-off switch on the secondary pipe is simultaneously opened to ensure that the gas transfer chamber 402 is connected to the inside of the gas storage tank 7. It is also necessary to appropriately increase the pressure value inside the gas storage tank 7 to ensure that the pressure environment inside the gas transfer chamber 402, the gas storage tank 7 and the water storage tank 3 is equal.

[0037] However, when the on-off switch is not turned on, pure water is added to the liquid replenishing tank through the water inlet. Due to the blocking effect of the liquid blocking piston 11, the pure water does not directly enter the upper side of the partition block 9 corresponding to the water storage tank 3, but directly enters the liquid transfer tank 401, causing the gas-liquid separation piston 10 to be subjected to upward pressure. Figure 5 Taking the positional relationship in as an example, by limiting the setting position of the gas-liquid separation piston 10, the two-way pipe is not connected to the interior of the transfer tank 4, so that the carbonated spring cannot be released. To solve this problem, the gas-liquid separation piston 10 can be driven upward to connect the middle position of the gas-liquid separation piston 10 with the two-way pipe and the three-way pipe at the same time, so that the carbonated spring is transferred to the auxiliary tank 5 under high pressure and sprayed out. The gas-liquid separation piston 10 can also be further driven downward to connect the two-way pipe and the three-way pipe with the interior of the gas transfer chamber 402, which can also ensure that the carbonated spring is transferred to the auxiliary tank 5 under high pressure and sprayed out.

[0038] S3: In the process of replenishing pure water, on the one hand, the pressure in the internal position on the upper side of the partition block 9 of the water storage tank 3 is reduced, and the pure water provides upward pressure on the pressurized cone cap 12, causing the pressurized cone cap 12 and the liquid blocking piston 11 to move up at the same time, so that the pure water is replenished from the liquid guide port to the upper end position of the partition block 9 of the water storage tank 3. However, in this process, the position of the gas-liquid separation piston 10 also needs to be kept stationary.

[0039] Example 3: The following supplementary explanation is provided based on the technical content of Example 1 and Example 2:

[0040] The present invention is directed to the release process of carbonated springs. The only variable is the pressure change caused by the change in volume. Specifically, after carbon dioxide is continuously charged into the water storage tank 3, when the carbon dioxide cannot dissolve in the pure water, the water storage tank 3 maintains a constant pressure environment. To this end, the peak pressure Vo in the water storage tank 3 is further set according to the solubility of the carbonated spring. After the internal pressure of the water storage tank 3 is maintained at the peak pressure Vo, the connection between the gas storage tank 7 and the water storage tank 3 is first closed by the opening and closing switch, and pure water is further added to the liquid replenishment tank through the water inlet, so that the internal position of the transfer tank 401 reaches the hydraulic peak Qs. Its essence is to ensure that the gas-liquid separation piston 10 is maintained at such a pressure. Figure 5 In the relevant position shown in FIG, because the liquid is difficult to be further compressed, after the on-off switch between the gas storage tank 7 and the transfer tank 4 is opened, the upper end of the gas-liquid separation piston 10 is subjected to the pressure environment from the gas storage tank 7 and the transfer tank 4. Moreover, because the internal pressure environment of the two is also "shared" by the transfer tank 402, the internal pressure environment of the gas storage tank 7 and the transfer tank 4 is reduced. Therefore, it is necessary to further increase the pressure inside the gas storage tank 7 by the micro air pump assembly 2 to continue to maintain the peak pressure Vo;

[0041] To this end, the present invention also requires establishing a dual pressure difference model during the carbonated spring release process through the control assembly 6. During operation, the following steps are included:

[0042] S4: When the carbonated spring needs to be released, a fixed amount of pure water is first discharged through the water inlet of the water storage tank 3. This reduces the peak hydraulic pressure Qs on the lower side of the gas-liquid separation piston 10, causing the gas-liquid separation piston 10 to move downward, connecting the two-way pipe with the interior of the gas transfer chamber 402. At the same time, the on-off switch between the gas storage tank 7 and the water storage tank 3 is opened. During this process, the carbonated spring in the water storage tank 3 first enters the gas transfer chamber 402, but does not enter the auxiliary tank 5 through the three-way pipe until the upper end of the gas-liquid separation piston 10 moves to the lower side of the three-way pipe, at which point the carbonated spring begins to be released.

[0043] S5: Different from S4, the water storage tank 3 and the air storage tank 7 are not connected, but the air storage tank 7 is connected to the transfer tank 4. First, the pressure environment inside the air storage tank 7 is reduced, and pure water is further injected into the liquid replenishment tank and the liquid transfer tank 401, so that the gas-liquid separation piston 10 moves upward, and the two-way pipe and the three-way pipe are connected through the liquid outlet tank 403. During this process, the carbonated spring inside the water storage tank 3 is in a released state, resulting in a decrease in the internal pressure environment. During this process, the air storage tank 7 and the water storage tank 3 can be further pressurized by the micro air pump assembly 2.

[0044] To illustrate with reference to S4 and S5, since the key technical point of the present invention lies in the air pressure value inside the water storage tank 3, the air pressure value Vt inside the water storage tank 3 can be monitored in real time by an air pressure sensor, and the hydraulic pressure value Qt exerted on the lower end of the liquid blocking piston 11 can be reversely calculated based on the water injection volume of the liquid replenishment tank. Specifically, it is expressed as: Qt = k*Ht, where Ht represents the water replenishment rate per unit time in the liquid replenishment tank and the liquid transfer tank 401, and K represents a conversion constant, which is specifically related to the sum of the volumes of the liquid replenishment tank and the liquid transfer tank 401. Therefore, during the process of releasing carbonated spring, the above-mentioned S4 is executed first, followed by S5. In S5, the on / off switches of the first-stage and second-stage pipes are simultaneously opened. To prevent the carbon dioxide in the carbonated spring in the water storage tank 3 from being precipitated, the water storage tank 3 is pressurized by the micro air pump assembly. During this process, because some carbonated spring is released, the air pressure value Vt in the water storage tank 3 needs to be higher than the peak air pressure. The value Vo is present, but to further maintain pressure balance in the water storage tank 3 and the gas storage tank 7, the present invention indirectly controls the pressure via the amount of pure water in the liquid replenishment tank and the liquid transfer tank 401. Specifically, the pressure environment in the water storage tank 3 also directly affects the upper position of the gas-liquid separation piston 10. A conversion method between Vt and k*Ht is established for this purpose. Taking the peak pressure Vo as an example, since the peak pressure Vo is specifically related to the solubility of carbon dioxide and the upper internal volume of the corresponding separator block 9 in the water storage tank 3, the carbonated spring volume in the water storage tank 3 is initially constant and thus maintained at the peak pressure Vo. Based on the peak pressure Vo, Vt is set within a range of 1.09*Vo to 1.59*Vo and substituted into the conversion method between Vt and k*Ht. This aims to further control Ht, both to prevent the precipitation of carbon dioxide from the carbonated spring due to temperature and to prevent excessive release pressure of the carbonated spring due to excessive pressure.

[0045] In summary: For the release process of carbonated spring application, the release process of carbonated spring is optimized based on the water storage tank and the transfer tank. The overall process only includes the change process of gas pressure. The liquid transfer tank in the transfer tank and the liquid replenishment tank in the water storage tank are used as the basis. Through the two-way conversion process of gas volume and liquid volume, in the release process of carbonated spring, the gas-liquid separation piston is first used as the active channel switch in the release process of carbonated spring. The movement process of the gas-liquid separation piston is directly related to the gas pressure of carbon dioxide and the liquid pressure of pure water. Therefore, in the actual operation process, a dual-pressure difference model is established. It is based on the two pressures and the pure water replenishment rate is the key. The key is used to maintain the pressure environment inside the water storage tank. On the one hand, it reduces the amount of carbon dioxide precipitation in the carbonated spring due to temperature, and also plays a role in stabilizing the release pressure of the carbonated spring.
