Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a device for ionizing condensed water to generate charged water particles in the air. Background Art

[0002] The products currently on the market produce charged water particles, i.e. water ions, by ionizing condensed water in the air. The high-voltage ionization of air is accompanied by the production of ozone O3, and ozone + condensed water produce highly active hydroxyl radicals OH under the action of the high-voltage electric field. Therefore, water ions contain electrons, water particles and hydroxyl radicals. Therefore, water ions have the characteristics of removing bacteria, mold, deodorizing, inhibiting allergens, and decomposing harmful gases, and are gradually used in products such as air purifiers, hair dryers, air conditioners, and disinfection machines.

[0003] This type of products on the market all achieve the functional effect of ionizing water molecules by discharging the needle tip to the ring, such as CN200580010614 electrostatic atomization device, CN201710238050 nano water ion generation method and device without adding water, CN201821546206 a nano small molecule water generation device, and CN202010555721 composite ion generation device and method. These patented solutions are to condense air moisture at the needle tip, pass high voltage between the needle tip and the metal ring, and ionize the moisture at the needle tip when ionizing the air, thereby generating charged water particles. These solutions can only ionize at the needle tip, and single-point charged water particles are generated, which is inefficient and has a low concentration of charged water particles. Therefore, the functional effect of products using this technology to generate water ions is not good and the market acceptance is poor.

[0004] In addition, these patent solutions simply use semiconductor refrigeration elements such as cooling sheets to reduce the temperature of the metal needle tip of the condensing element to condense air moisture, but do not consider the factors that affect the condensation effect, such as the temperature of the metal needle tip of the condensing element, the temperature and humidity in the air, which either results in excessive moisture at the needle tip, hindering the generation of ionization, resulting in the inability to generate charged water particles or reducing the concentration of charged water particles. Or, because the dew point temperature cannot be reached, condensed water cannot be generated, and charged water particles cannot be ionized.

[0005] These patented solutions all expose high-voltage metal electrodes to the air. Under the influence of multiple factors such as air moisture, oxygen, high voltage and air pollutants, the high-voltage metal electrodes are easily oxidized and corroded and fail. Summary of the invention

[0006] The purpose of the utility model is to provide a device for ionizing condensed water to produce charged water particles in the air. During the use of the ionized air, the high-voltage electrode is not easy to oxidize, corrode, and rust, has good working stability and durability, and can generate charged water particles in the air reliably, durable, with a simple structure and stable effect.

[0011] According to the optimization scheme, a temperature sensor is also provided near the reference ground electrode plate of the ionization sheet. Furthermore, a plurality of temperature sensors are arranged in sequence and spaced apart along the length direction of the ionization sheet. Furthermore, a detection probe of the temperature sensor is wrapped by a thermally conductive insulator, and the outer surface of the thermally conductive insulator contacts the reference ground electrode plate.

[0012] According to the optimization scheme, a temperature and humidity sensor is also arranged near the ionization plate, and the temperature and humidity sensor is far away from the semiconductor refrigeration plate.

[0013] According to an optimized solution, a plurality of fans are provided near the ionization sheet and are arranged in sequence and spaced apart along the length direction of the ionization sheet, and the air outlet ends of the fans face the ionization sheet.

[0014] According to an optimization scheme, the reference ground electrode plate is a hollow grid structure having a plurality of mesh holes, and the conductive layer is a grid structure arranged in a one-to-one correspondence with the reference ground electrode plate.

[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] Example

[0028] refer to Figures 1 to 6 , a device for ionizing condensed water to generate charged water particles in the air, comprising an ionization sheet 1, wherein the ionization sheet 1 is a long strip-shaped sheet structure having a conductive layer 11, a reference ground electrode plate 12 and a dielectric barrier 13, wherein the dielectric barrier 13 is located between the conductive layer 11 and the reference ground electrode plate 12. In this embodiment, Figure 3 , the dielectric barrier 13 adopts a ceramic carrier material, the conductive layer 11 is coated on one side surface of the dielectric barrier 13, and the reference ground electrode plate 12 is fixedly connected to the other side surface of the dielectric barrier 13. The reference ground electrode plate 12 is a hollow grid structure with a plurality of mesh holes, and the conductive layer 11 is a grid structure arranged one-to-one with the reference ground electrode plate 12. Furthermore, the ionization sheet 1 also has another dielectric barrier 13 along the thickness direction, and the conductive layer 11 is arranged between the two dielectric barriers 13. Furthermore, the conductive layer 11 is sintered inside the ceramic carrier between the two dielectric barriers 13, isolated from the external space, and the ceramic carrier plays an insulating and sealing role for the high-voltage electrode, which is safe and reliable. For the specific structure, please refer to the Chinese utility model patent application number 202322315345.3 of the applicant.

[0029] The ionization plate 1 is provided with a semiconductor cooling plate 2 near the reference ground electrode plate 12 . The two ends of the semiconductor cooling plate 2 have a cold side and a hot side respectively. The cold side is provided near the reference ground electrode plate 12 .

[0030] In the above structure, the cold side of the semiconductor refrigeration plate 2 is close to the reference ground electrode plate 12 to exchange heat with the air, so as to cool the reference ground electrode plate 12 so as to condense water from the surrounding air on the reference ground electrode plate 12. Condensed water is generated on the surface of the reference ground electrode plate 12, and an electric potential difference is formed between the conductive layer 11 to ionize the air and generate charged water particles.

[0031] In order to improve the cooling effect of the reference ground electrode plate 12, as Figure 6 , and further contact the cold side of the semiconductor refrigeration plate 2 with the reference ground electrode plate 12.

[0032] The device further includes a heat sink 3, which is attached to the hot side of the semiconductor cooling plate 2. In this embodiment, the heat sink 3 is specifically a comb-shaped aluminum alloy material, which is in contact with the hot side of the semiconductor cooling plate 2 to dissipate its heat into the air, thereby improving the cooling efficiency of the semiconductor cooling plate 2.

[0033] The ionization sheet 1 is also provided with a temperature sensor 4 near the reference ground electrode plate 12. Furthermore, the detection probe of the temperature sensor 4 is wrapped by a thermally conductive insulator (not shown in the figure), and the outer surface of the thermally conductive insulator contacts the reference ground electrode plate 12. In the above structure, the thermally conductive insulator is made of a high thermal conductivity insulating silicone material, which plays a role of heat conduction and insulation, and contacts the reference ground electrode plate 12 and the detection probe of the temperature sensor 4 respectively, so that the reference ground electrode plate 12 and the temperature detection probe are insulated and isolated, but can also conduct heat. The heat on the reference ground electrode plate 12 is first conducted to the high thermal conductivity insulating silicone, and then the high thermal conductivity insulating silicone conducts the heat to the temperature detection probe, thereby achieving insulation isolation between the temperature detection probe and the reference ground electrode plate 12, and detecting the condensation temperature on the reference ground electrode plate 12.

[0034] A temperature and humidity sensor 5 is also provided near the ionization sheet 1, and the temperature and humidity sensor 5 is far away from the semiconductor refrigeration sheet 2. In the above structure, the temperature and humidity sensor 5 is used to detect the real-time temperature and humidity values ​​of the ambient air and is electrically connected to the main board of the device to transmit the detected temperature and humidity parameters to the main board.

[0035] The operating principle of the device for generating charged water particles in the air by ionizing condensed water in this embodiment is as follows:

[0036] 1. The semiconductor cooling sheet 2 is a device that uses the thermoelectric effect of semiconductors to produce cooling, and is divided into a cold side and a hot side. The cold side cools the reference ground electrode plate 12 and condenses moisture in the surrounding air on the reference ground electrode plate 12. The hot side contacts the radiator 3 and transfers heat to the radiator 3.

[0037] 2. Use a high-voltage power supply to apply high voltage to the conductive layer 11 and the reference ground electrode plate 12 to form a potential difference between the two. The grid of the conductive layer 11 discharges to the grid on the reference ground electrode plate 12 to ionize the air. The condensed water on the reference ground electrode plate 12 is ionized, atomized, and miniaturized, thereby generating charged water particles, which are carried out by the airflow generated by the fan 6 and enter the indoor environment air where the device is used.

[0038] 3. During the cooling process of the reference ground electrode plate 12 by the semiconductor refrigeration plate 2, the temperature is lower the closer to the semiconductor refrigeration plate 2 and higher the farther away from the semiconductor refrigeration plate 2, so the condensation temperature on the reference ground electrode plate 12 is not consistent. In order to achieve uniform generation of condensed water on the reference ground electrode plate 12, the surface temperature of the reference ground electrode plate 12 must be adjusted in different regions so that the surface temperature of each region approaches or is lower than the dew point temperature.

[0039] In this embodiment, the reference ground electrode plate 12 is divided into four ionization areas as an example, and the temperature detection is performed on each ionization area on the reference ground electrode plate 12 to obtain the real-time temperature. The four ionization areas correspond to four temperature sensors 4 and four fans 6 with independently controlled speeds, respectively. Specifically, the four temperature sensors 4 are arranged in sequence along the length direction of the ionization sheet 1. And four fans 6 are arranged in sequence along the length direction of the ionization sheet 1 near the ionization sheet 1, and the air outlet of the fan 6 is directly facing the ionization sheet 1. The lower the surface temperature of the partition, the faster the speed of the corresponding fan 6, which accelerates the heat exchange between the ionization area corresponding to the reference ground electrode plate 12 and the air, and promotes the dissipation of cold and the increase of temperature in the ionization area. On the contrary, the higher the surface temperature of the partition, the slower the speed of the corresponding fan 6, which reduces the heat exchange between the ionization area corresponding to the reference ground electrode plate 12 and the air, reduces the dissipation of cold and the temperature of the ionization area, and thus makes the condensation temperature of each ionization partition relatively consistent.

[0040] 4. Because electric charges will accumulate on the reference ground electrode plate 12 during the process of ionizing the air, the electric charges will damage the detection probe of the temperature sensor 4. Therefore, the temperature detection probe cannot be directly used to contact the electrode plate to detect the temperature. Therefore, the temperature detection probe is wrapped with high thermal conductivity insulating silica gel. High thermal conductivity insulating silica gel plays the role of heat conduction and insulation, and contacts the reference ground electrode plate 12 and the temperature detection probe respectively, so that the reference ground electrode plate 12 and the temperature detection probe are insulated and isolated, but can also conduct heat. The heat on the reference ground electrode plate 12 is first conducted to the high thermal conductivity insulating silica gel, and then the high thermal conductivity insulating silica gel conducts the heat to the temperature detection probe, thereby realizing the insulation isolation between the temperature detection probe and the reference ground electrode plate 12, and the condensation temperature on the reference ground electrode plate 12 can be detected. The temperature sensor 4 detects the temperature T1 (°C) of the high thermal conductivity insulating silicone, thereby indirectly detecting the condensation temperature T2 (°C) on the reference ground electrode plate 12, and transmits the temperature data to the main board, where the T1 value is approximately equal to the T2 value, that is, the T1 value detected by the temperature sensor 4 can be used as the condensation temperature T2 (°C) value on the reference ground electrode plate 12 very accurately.

[0041] like Figure 1 As shown, the temperature and humidity sensor 5 is fixed in the device to detect the real-time temperature and humidity values ​​of the ambient air, and transmit the detected temperature and humidity parameters to the main board. After the ambient air temperature T (℃) and the relative humidity (RH%) of the air are detected, the approximate value of the dew point temperature Td (℃) can be calculated by the Magnus-Tetens approximation method:

[0042]

[0043] ln is the natural logarithm. Constants a = 17.27, b = 237.7.

[0044] After the mainboard calculates the real-time dew point temperature Td (°C) through the above formula, the mainboard adjusts the cooling power by adjusting the power supply duty cycle of the semiconductor refrigeration plate 2, and adjusts the surface heat exchange layer of the "reference ground electrode plate 12" in each ionization area by controlling the speed of each ionization partition fan 6, thereby controlling the surface temperature of the "reference ground electrode plate 12" in each ionization partition, so that the surface temperature of the "reference ground electrode plate 12" in each ionization partition is driven to the theoretically calculated dew point temperature, thereby accurately controlling the amount of condensed water, improving the ionization effect, and producing high-concentration charged water particles. The temperature T1 (°C) on the surface of the electrode plate in each ionization area is controlled to be lower than the dew point temperature Td (°C) under the real-time environmental parameters, ensuring the occurrence of condensation, accurately controlling the amount of condensed water, and improving the ionization effect, thereby producing high-concentration charged water particles in the ionization area.

[0045] In order to produce an appropriate amount of water on the reference ground electrode plate 12 by condensation and ensure the stable generation of the ionization phenomenon, the device was tested in a laboratory environment, and a T1 (℃) temperature comparison table was obtained under different room temperatures and different indoor relative humidity (such as Figure 7 ), and the corresponding line graph is obtained through computer conversion (such as Figure 8 ). When the temperature T1 (℃) reaches the temperature in the reference table, the test shows that the amount of water produced by condensation on the reference ground electrode plate 12 is appropriate, and the ionization phenomenon occurs stably. Further, by comparing the dew point temperature Td (℃) obtained by theoretical calculation with the temperature T1 (℃) obtained by experiment, it is concluded that the temperature T1 (℃) is equal to the dew point temperature Td (℃)-1.5±0.5℃, and the deviation value is set to a, and a is 1.5±0.5℃. When the temperature and humidity sensor 5 detects the indoor temperature and humidity and outputs the data to the mainboard MCU, the MCU theoretically calculates the dew point temperature Td (℃) and calculates the theoretical value of the temperature T1 (℃) according to the above calculation model "Td (℃)-a=T1 (℃)". At this time, the theoretical value T1 (℃) is the most suitable condensation temperature. The mainboard adjusts the surface temperature of the ionization partition to the most suitable condensation temperature T1 (℃) by adjusting the cooling power of the semiconductor refrigeration plate 2 and the speed of the fan 6, so as to achieve a better condensation amount and a better ionization effect.
