Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an air purification system based on ecological-grade negative oxygen ions and its usage method. Background Technology

[0002] A fresh air system is a ventilation and air exchange device that supplies fresh air to a room mechanically or naturally while expelling stale air. Its main functions are ventilation when windows are closed and purification of the air brought into the room. Often referred to as the "breathing system of a house," fresh air systems provide residents with a healthy and comfortable indoor air environment through their unique working principle. With the continuous development of the economy and society, people have increasingly higher demands for quality of life, leading to the emergence of the concept of air purification. This system purifies the incoming fresh air while replacing indoor air, thereby achieving a healthier air environment.

[0003] Ecological-grade negative oxygen ions are equivalent to natural air negative ions. They are small-diameter negative oxygen ions, also called light ions or small ions, and are characterized by high activity and long migration distance. They can easily penetrate the blood-brain barrier and play an important role in human health. Therefore, negative oxygen ions are often used in some fresh air systems.

[0004] Existing fresh air systems tend to use negative ions in a rigid manner, with the amount and timing of ion input typically set manually. However, in real-world environments, indoor air quality is affected by factors such as the number of people, their activities, and the daily temperature and humidity, meaning existing fresh air systems cannot adjust themselves to meet actual needs.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-11 The present invention provides a technical solution: an air purification system based on ecological-grade negative oxygen ions, including an air purification box 1. The air purification box 1 is provided with several partitions 11. The partitions 11 divide the area inside the air purification box 1 into an input area 12, a purification area 13, a power area 14, and an output area 15. The input area 12 is connected to the indoor and outdoor environments respectively and is used to input indoor or outdoor air. The purification area 13 is used to purify the input air. The power area 14 is used to extract air. The output area 15 is connected to the indoor environment and is used to output purified air into the room. A mounting frame 2 is installed in the purification zone 13. An ultraviolet lamp 3 is fixed on the mounting frame 2. A fixed inner cylinder 4 is installed outside the ultraviolet lamp 3. Several windows 41 are opened around the surface of the fixed inner cylinder 4. A movable outer cylinder 5 is fitted outside the fixed inner cylinder 4. A window 51 matching the window 41 is opened around the surface of the movable outer cylinder 5. A side tooth 52 is provided on one side of the movable outer cylinder 5. A driving component is installed in the side tooth 52. The driving component is connected to a negative oxygen ion component.

[0025] In one embodiment, such as Figure 3 As shown, the drive assembly includes a motor 61. The drive shaft of the motor 61 is fitted with a drive gear 62 and a drive gear 63 in sequence. The drive gear 63 cooperates with the side gear 52 to drive the movable outer cylinder 5 to rotate. The drive gear 62 is connected to the driven gear 64 via a belt.

[0026] like Figure 4 As shown, the negative oxygen ion component includes a fixed base 71, a screw 72 is internally threaded onto the fixed base 71, the screw 72 is engaged with the driven tooth 64, an ion output cylinder 73 is fixed to one end of the screw 72, several output holes 731 are opened on the surface of the ion output cylinder 73, a negative oxygen ion generator is installed inside the ion output cylinder 73, and a sealing cylinder 74 is fixed to one side of the driven tooth 64.

[0027] The following is a supplementary explanation based on the above structure: The overlap between the fixed inner cylinder 4 and the movable outer cylinder 5 can be used to control the illumination range of the ultraviolet lamp 3, thereby adjusting the irradiation intensity of the ultraviolet lamp 3. The irradiation intensity of the ultraviolet lamp 3 is directly proportional to the degree of overlap between window one 41 and window two 51. When window one 41 and window two 51 are completely offset, the fixed inner cylinder 4 and the movable outer cylinder 5 form a closed structure, isolating the light from the ultraviolet lamp 3 from the outside world; when window one 41 and window two 51 are completely overlapped, the window area connected to the outside world formed by the fixed inner cylinder 4 and the movable outer cylinder 5 is the largest, and at this time, the illumination range of the ultraviolet lamp 3 is the largest, that is, the irradiation intensity is the greatest.

[0028] In actual operation, motor 61 drives the movable outer cylinder 5 to rotate via drive gear 63, thereby adjusting the overlap between window 41 and window 51. Motor 61 drives driven gear 64 to rotate via drive gear 62, which in turn drives screw 72 to rotate, causing screw 72 to move forward or backward relative to fixed base 71, thus pushing ion output cylinder 73 out of sealed cylinder 74. Ions produced by the negative ion generator enter the air through output port 731. The extent to which ion output cylinder 73 extends out of sealed cylinder 74 determines the number of output ports 731 that communicate with the outside, thus corresponding to the rate at which negative ions are emitted into the air. Furthermore, the extent to which ion output cylinder 73 extends out of sealed cylinder 74 corresponds to the degree of overlap between window 41 and window 51; that is, when window 41 and window 51 are completely offset, output cylinder 73 is completely retracted into sealed cylinder 74; when window 41 and window 51 are completely overlapped, output cylinder 73 is completely extended out of sealed cylinder 74.

[0029] like Figure 6 As shown, a connecting plate 42 is provided at the bottom of the fixed inner cylinder 4, and a circular groove 43 is provided on the outer periphery of the connecting plate 42.

[0030] like Figure 7 As shown, the circular groove 43 is connected to the movable inner cylinder 81. The movable inner cylinder 81 includes two circular frames 811 at both ends and several supports 812 that connect the circular frames 811. A brush 813 is provided on the inward side of the support 812.

[0031] like Figure 5 As shown, a positioning frame 53 is provided on the other side of the movable outer cylinder 5 relative to the side tooth 52.

[0032] Furthermore, such as Figures 8-10 As shown, the positioning frame 53 is equipped with a connecting seat 82, the connecting seat 82 is equipped with a first connecting area 821, the connecting seat 82 is equipped with a second connecting area 822, the connecting seat 82 is equipped with a circular frame 811, the first connecting area 821 is equipped with several magnetic blocks 823, and the second connecting area 822 is equipped with magnetic modules.

[0033] A torsion spring 83 is connected to the bottom of the connecting seat 82, and a movable seat 84 is connected to the other end of the torsion spring 83. The inner diameter of the movable seat 84 matches the outer diameter of the connecting seat 82, and the movable seat 84 and the connecting seat 82 are rotatably engaged. An electric push rod 85 is connected to the bottom of the movable seat 84. The electric push rod 85 is fixed on the inner wall of the clean area 13, and several guide rods 86 are provided between the electric push rod 85 and the movable seat 84.

[0034] The following is a supplementary explanation based on the above structure: Connection area 1 821 is used to attract the positioning frame 53, thereby connecting it to the movable outer cylinder 5; Connection area 2 822 is used to attract the circular frame 811, thereby connecting it to the movable inner cylinder 81. When the magnetic block 823 and the magnetic module are energized, they generate magnetic attraction. The positioning frame 53 and the circular frame 811 are made of materials suitable for attraction by default. When the electric push rod 85 pushes the moving seat 84, the connection area 1 821 and the connection area 2 822 are energized with the positioning frame 53, the circular frame 811, the magnetic block 823, and the magnetic module, respectively, thus connecting them to each other. At this time, when the movable outer cylinder 5 rotates, it will synchronously drive the connection seat 82 and the movable inner cylinder 81 to rotate. When the magnetic block 823 is de-energized, the torsion spring 83 will drive the connection seat 82 and the movable inner cylinder 81 to reset.

[0035] In one embodiment, a ring of brushes 741 is provided on the open side of the sealing cylinder 74 for cleaning each output hole 731. That is, when the ion output cylinder 73 is pulled back into the sealing cylinder 74, the brushes 741 come into contact with the surface of the ion output cylinder 73 and remove the attached impurities. When the ion output cylinder 73 is completely pulled back into the sealing cylinder 74, the brushes 741 can act as a sealing ring to cooperate with the sealing cylinder 74 to isolate the ion output cylinder 73 from the outside world and prevent external impurities from seeping in.

[0036] Furthermore, brushes 824 are provided on both sides of the magnetic block 823 to clean the adsorption position of the positioning frame 53. That is, when the connecting seat 82 rotates, the brushes 824 will clean the rotation path of the magnetic block 823, which can reduce the wear of the magnetic block 823 caused by impurities.

[0037] It should be noted that brush 1 (813) is used to clean the surface of the UV lamp 3 to prevent impurities from affecting the light intensity of the UV lamp 3. Brush 1 (813), brush 2 (741), and brush 3 (824) are the cleaning modules for the purification zone 13.

[0038] like Figure 11 As shown, the purification zone 13 is equipped with several filter plates 131 relative to the air output side to filter out impurity particles in the circulating gas. A temperature sensor is installed in the purification zone 13 to detect the real-time temperature.

[0039] The input area 12 has inlet 121 and inlet 122, corresponding to indoor and outdoor air respectively. A valve body 123 is installed within the input area 12, and a motor 124 is connected to the valve body 123. In actual operation, the valve body 123 can block either inlet 121 or inlet 122. The motor 124 controls the deflection of the valve body 123, thus switching between indoor and outdoor air input.

[0040] A fixed frame 16 is provided between the power zone 14 and the output zone 15. A fan 141 is provided in the power zone 14. The output end of the fan 141 is connected to the fixed frame 16. The fixed frame 16 is equipped with a mesh window in conjunction with the fan 141. A pressure sensor is provided in the mesh window to detect the pressure of the air output by the fan 141.

[0041] The output area 15 has an outlet 151 that connects to the interior. A valve body 152 is installed inside the output area 15, and a motor 153 is connected to the valve body 152. In actual operation, the valve body 152 is used to open and close the outlet 151. Optionally, several filter plates 131 are installed on the outside of the outlet 151 to isolate external impurities.

[0042] The specific implementation method is as follows: In this case, the air purification system mainly includes two modes: indoor-indoor air circulation and outdoor-indoor air circulation.

[0043] ①Indoor-Indoor: Valve 123 turns to inlet 2 122, sealing the passage between air purification box 1 and the outside. Fan 141 starts, and indoor air is introduced into purification zone 13 through inlet 121. After being disinfected by ultraviolet lamp 3, the air carrying negative oxygen ions produced by the negative oxygen ion component is filtered through filter plate 131 and then output to the indoor air through outlet 151, forming a purification cycle of indoor air.

[0044] ②Outdoor-Indoor: When it is necessary to introduce outdoor air into the room, valve body 123 turns to inlet 121, opening the passage between air purification box 1 and the outside. The remaining steps are the same as ①, to achieve the purpose of purifying the outdoor airflow.

[0045] Furthermore, the intensity of the ultraviolet lamp 3 and the output of negative oxygen ions are adjusted according to the airflow input pressure.

[0046] Specifically, assuming the pressure value monitored by the pressure sensor in real time is F1, the power of the fan 141 remains unchanged, and the ideal pressure limit value is set to F0.

[0047] When F1≥F0, it indicates that the impurity content in the airflow is within the ideal range, and the proportion of clean airflow in the introduced airflow is high, so that the airflow can quickly pass through the filter plate 131. At this time, the demand for the light of the ultraviolet lamp 3 and the negative oxygen ions is relatively small, and the light range and the output of negative oxygen ions of the ultraviolet lamp 3 can be adjusted to a lower range.

[0048] When F1 < F0, it indicates that the impurity content in the airflow exceeds the ideal range, and the proportion of impurities in the introduced airflow is high, making it impossible for the airflow to pass through the filter plate 131 quickly. At this time, the demand for the light and negative oxygen ions of the ultraviolet lamp 3 is greater. F1 can be graded according to the demand, and the light range and negative oxygen ion output of the ultraviolet lamp 3 can be adjusted according to the actual needs.

[0049] For example: Introduce the grading parameters a and b, 0 < a < b < 1. When F1 < a * F0, the airflow purification requirement level is I, which corresponds to the highest requirement. At this time, the illumination range of the ultraviolet lamp 3 and the output of negative oxygen ions need to be adjusted to the maximum. When a*F0≤F1≤b*F0, the airflow purification requirement level is Level II, which corresponds to medium requirement. At this time, the illumination range of UV lamp 3 and the output of negative oxygen ions need to be adjusted to 2 / 3. When F1 > b*F0, the airflow purification requirement level is Level III, corresponding to a low requirement. At this time, the illumination range of UV lamp 3 and the output of negative oxygen ions need to be adjusted to 1 / 3.

[0050] Furthermore, based on the above control methods, a temperature parameter is introduced. As the temperature increases, the luminous efficiency and radiation intensity of the ultraviolet lamp typically increase. Therefore, a temperature-influencing parameter T0 is set. When the real-time temperature T detected by the temperature sensor within the purification zone 13 is greater than the temperature-influencing parameter T0, the temperature within the purification zone 13 can significantly affect the irradiation intensity of the ultraviolet lamp, and the purification requirement level should be downgraded.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0052] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
