Description

Technical Field

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

[0002] Carbonated spring is essentially water dissolved with carbon dioxide. Because it is weakly acidic, it is not only good for cardiovascular health, but also can improve scalp problems. It is commonly used in skin care / head cleaning. Please refer to the relevant content in the announcement number CN219231038U. Take the household carbonated spring cleaner as an example. Its essence is to spray carbonated spring in the form of nano-water mist under pressure, which plays the role of pore massage and cleaning.

[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. Carbonated springs used for skin care / head cleaning need to be heated to a suitable temperature first. In order to ensure the amount of carbon dioxide dissolved in the carbonated spring, the internal environmental pressure of structures such as water storage tanks needs to be further increased. However, in the process of releasing carbonated springs, 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 carbonated springs. Due to the change in the pH value of carbonated springs, the effect of carbonated springs is minimal.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide an ultra-fine water mist spray cleaning device. For household carbonated spring spray cleaning devices, when carbonated spring is released in the form of nano water mist, on the basis of a constant temperature, the internal pressure environment of the structure storing the carbonated spring changes, causing carbon dioxide to precipitate and affecting the pH value of the carbonated spring, resulting in minimal effect of the carbonated spring.

[0010] It is further configured as follows: an on-off switch is provided on the first-stage tube and the second-stage tube.

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 key content is to establish a dual pressure difference model for the process of carbonated spring release. It is based on two pressures and the 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". 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 precipitated in the carbonated spring due to temperature, and also plays a role in stabilizing the release pressure of the carbonated spring.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: For household carbonated spring spray cleaning devices, when carbonated spring is released 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 affecting the pH value of the carbonated spring, resulting in minimal effect of the carbonated spring. The following technical solution is proposed:

[0029] 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 arranged inside the housing 1, and a water circulation assembly corresponding to the air storage tank 7 is arranged inside the housing 1;

[0030] 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 provided with a water inlet and a water outlet that penetrate to the outside of the shell 1. The top end of the air storage tank 7 is provided with a double-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 component 2 is installed at the lower side position corresponding to the air storage tank 7, and the micro air pump component 2 is used for pressurizing the inside of the air storage tank 7. The double-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 ends 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 double-way joint pipe 8. The first-order pipe and the second-order pipe are provided with an opening and closing switch.

[0031] Basic principle: A brief description of carbonated spring is that its essence is based on a high-pressure environment, "forcing" 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 inject an appropriate amount of pure water into the water tank 3, and then continuously pressurize the inside of the gas tank 7 through the micro air pump assembly 2, and the inside of the gas tank 7 is used as a storage structure for carbon dioxide. Therefore, under the pressurization 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 will also be continuously pressurized. It should be supplemented here that the ultra-fine water mist spray washer proposed by the present invention is mainly used in head care work, and for this purpose, the pure water in the water tank 3 needs to be heated to a suitable temperature, such as 30°C. It can be understood that the inside of the water tank 3 is mainly used as a preparation structure and storage structure for carbonated spring;

[0032] In the subsequent use process, 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 high pressure. 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.

[0033] Embodiment 2: Supplementary explanation of the water circulation process of the water circulation component in Embodiment 1:

[0034] A liquid blocking piston 11 and a pressure cone cap 12 are respectively arranged at the upper and lower positions of the partition block 9, a liquid guiding column is connected between the liquid blocking piston 11 and the pressure cone cap 12, a liquid guiding column and the partition block 9 are slidably connected, 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, a slidably connected between the pressure cone cap 12 and the inner wall of the water storage tank 3, a liquid replenishing bin is arranged at the inner position of the water storage tank 3 corresponding to the lower side of the pressure cone cap 12, and the diameter of the middle section of the gas-liquid separation piston 10 is smaller than the inner diameter of the transfer tank 4;

[0035] The interior of the transfer tank 4 is provided with a gas transfer bin 402, a liquid outlet bin 403 and a liquid transfer bin 401 arranged from top to bottom through the gas-liquid separation piston 10. 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 on the upper side of the dividing block 9 of the water storage tank 3 and the gas transfer bin 402 or the liquid outlet bin 403. The assisting tank 5 is installed with a three-way pipe corresponding to the transfer tank 4, and the positions where the three-way pipe, the two-way pipe and the transfer tank 4 intersect are not on the same horizontal plane.

[0036] 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, but the higher the temperature, the carbon dioxide will also precipitate from the water. The following explanation is made for this:

[0037] S1: After a proper amount of pure water is filled into the water storage tank 3, if the internal volume of the water storage tank 3 is V, the amount of pure inlet water added is 2 / 3*V, because 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. Because the setting temperature of the pure inlet water is in a constant state, only the correlation between the pressure condition and the solubility of carbon dioxide is considered. After part of the carbon dioxide is dissolved in the water to form a 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 in a constant state. However, after the carbonated spring inside the water storage tank 3 is discharged, its internal pressure environment is directly reduced, so there will also be a problem of carbon dioxide precipitation. If the internal pressure environment of the water storage tank 3 is increased simultaneously, the spray pressure of the carbonated spring will be too high. This part is the basic content that the present invention needs to solve;

[0038] 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 explain, the liquid blocking piston 11 at the upper side bears the downward pressure from the carbonated spring and blocks the partition block 9, and in this process, the opening and closing switch on the second-stage pipe is opened synchronously to ensure that the gas transfer bin 402 is connected to the inside of the gas storage tank 7, and the pressure value inside the gas storage tank 7 needs to be appropriately increased to ensure that the pressure environment inside the gas transfer bin 402, the gas storage tank 7 and the water storage tank 3 is equal;

[0039] 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 water storage tank 3 corresponding to the partition block 9, 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 inside of the transfer tank 4, so that the carbonated spring will not be released. For this, the gas-liquid separation piston 10 can be driven to move upward, so that the middle position of the gas-liquid separation piston 10 is connected to 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 conditions and sprayed out, and the gas-liquid separation piston 10 can be further driven to move downward, so that the two-way pipe and the three-way pipe are connected to the inside of the gas transfer warehouse 402, which can also ensure that the carbonated spring is transferred to the auxiliary tank 5 under high pressure conditions and sprayed out;

[0040] 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 an 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.

[0041] Embodiment 3: The following supplementary explanation is made based on the technical contents in Embodiment 1 and Embodiment 2:

[0042] The only variable in the release process of carbonated springs of the present invention is the pressure change caused by the change in volume, which is specifically manifested as follows: after carbon dioxide is continuously charged into the water storage tank 3, when carbon dioxide cannot be dissolved in pure water, a constant pressure environment is maintained in the water storage tank 3. For this, 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 liquid transfer tank 401 reaches the hydraulic pressure peak Qs;

[0043] The essence is to ensure that the gas-liquid separation piston 10 is maintained at Figure 5 In the relevant position shown in the figure, 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, and because the internal pressure environment of the two is also "shared" through the transfer tank 402, the internal pressure environment of the gas storage tank 7 and the transfer tank 4 is reduced. For this, it is necessary to further pressurize the inside of the gas storage tank 7 through the micro air pump assembly 2 to continue to maintain the peak pressure Vo;

[0044] For this purpose, the present invention also needs to establish a dual pressure difference model in the process of carbonated spring release through the control assembly 6, and during operation, the following process is included:

[0045] S4: When it is necessary to release the carbonated spring, a certain amount of pure water is first discharged through the water inlet in the water storage tank 3, so that the hydraulic peak value Qs borne by the lower side of the gas-liquid separation piston 10 is reduced, causing the gas-liquid separation piston 10 to move downward, so that the two-way pipe is first connected with the inside of the gas transfer bin 402, and the opening and closing switch between the gas storage tank 7 and the water storage tank 3 is opened synchronously. In this process, the carbonated spring in the water storage tank 3 first enters the gas transfer bin 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, and the carbonated spring begins to be released;

[0046] S5: Different from S4, the water storage tank 3 is not connected to the air storage tank 7, but the air storage tank 7 is connected to the inside of 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 up, and the two-way pipe and the three-way pipe are connected through the liquid outlet tank 403. In 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. In this process, the air storage tank 7 and the water storage tank 3 can be further pressurized by the micro air pump assembly 2.

[0047] In combination with 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 the air pressure sensor, and the hydraulic pressure value Qt borne by the lower end of the blocking piston 11 can be reversely calculated according to the water injection amount of the liquid replenishing tank, which is specifically expressed as: Qt=k*Ht, wherein Ht represents the water replenishment rate per unit time in the liquid replenishing 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 replenishing tank and the liquid transfer tank 401;

[0048] Therefore, in the process of releasing the carbonated spring, the above-mentioned S4 content is first executed, and then the S5 content is executed. In S5, the on-off switches in the first-stage tube and the second-stage tube are opened at the same time. In order 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. In this process, because part of the carbonated spring is released, the air pressure value Vt in the water storage tank 3 needs to be higher than the air pressure peak value Vo. However, in order to further maintain the pressure balance in the water storage tank 3 and the air storage tank 7;

[0049] The present invention specifically controls indirectly through the amount of pure water in the liquid replenishment tank and the liquid transfer tank 401, which is specifically manifested as follows: the pressure environment in the water storage tank 3 will also directly act on the upper position of the gas-liquid separation piston 10, and a conversion method between Vt and k*Ht is established for this, and the peak pressure Vo is taken as an example. Because the peak pressure Vo is specifically related to the solubility of carbon dioxide and the internal volume of the upper side of the partition block 9 corresponding to the water storage tank 3, in the initial state, the capacity of the carbonated spring inside the water storage tank 3 is a constant value, so as to maintain it in the peak pressure Vo. The range of Vt is set to 1.09*Vo~1.59*Vo based on the peak pressure Vo, and it is substituted into the conversion method of Vt and k*Ht. The purpose is to further control Ht therein, on the one hand to avoid the precipitation of carbon dioxide in the carbonated spring due to temperature, and also to avoid excessive release pressure of the carbonated spring due to excessive pressure.

[0050] In summary: for the release process in the application of carbonated springs, the release process of carbonated springs is optimized based on the water storage tank and the transfer tank. The overall process only includes the change process of gas pressure. For this, 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 springs, the gas-liquid separation piston is first used as the active channel switch in the release process of carbonated springs, and 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. For this, in the actual operation process, a dual pressure difference model is established. It is based on two pressures and the replenishment rate of pure water is the key. The key is to maintain the pressure environment inside the water storage tank. On the one hand, it reduces the precipitation of carbon dioxide in the carbonated spring due to temperature, and also plays a role in stabilizing the release pressure of the carbonated spring.
