Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of negative ion purification devices, in particular to a negative ion purification device for indoor environment. BACKGROUND

[0002] With the continuous acceleration of modernization process, people's stay in indoor environment continues to increase, and the influence of indoor air quality on human health is therefore increasingly prominent. When the air quality is poor, not only will it interfere with the comfort of daily life, but also will pose a substantial threat to human health. Long-term exposure to such an environment may cause respiratory discomfort, decreased immunity and a series of problems. In this context, improving indoor environmental quality with the help of negative ion purification devices has become an urgent need to protect people's quality of life and health.

[0003] Although the existing negative ion purification device can meet the basic needs of daily indoor air purification, in the actual operation process, the core component, the negative ion generator, is always in a continuous discharge state. This uninterrupted discharge process is accompanied by a large amount of energy conversion, part of which is released in the form of heat, causing the temperature of the generator itself to gradually rise. Long-term high-temperature environment can have multiple effects on the internal structure of the negative ion generator: the electrode material may be oxidized or aged due to continuous high temperature, shortening the effective service life of the electrode; internal circuit components such as capacitors, resistors, etc. may gradually lose their insulation performance under long-term high-temperature baking, and even cause short circuits and other faults; in addition, high temperature may also accelerate the aging and cracking of the insulating glue inside the generator, further increasing the risk of equipment damage. This component wear caused by continuous high temperature directly shortens the overall service life of the negative ion purification device, which often experiences a sharp decline in purification efficiency, an increase in operating noise, or even complete shutdown after frequent use for a few months. Not only does this increase the user's replacement cost, but it also affects the continuity and stability of air purification, thereby making the overall use of the negative ion purification device less effective.

After completing this initialization operation, the whole device can rely on pure mechanical structure to realize stable movement operation in the subsequent operation process, without additional manual intervention.

[0021] In the embodiment, the middle part of the driving frame 13 is fixed on the upper end of the fixed rod 11, a plurality of driving grooves 14 are penetrated in the middle part of the driving frame 13, the outer surface of the driving rod 30 is in contact with the inner wall of one of the driving grooves 14, the upper end of the driving rod 30 is fixed on the lower end of the frame body 28, the outer surface of the frame body 28 is slidingly connected with the inner wall of the frame groove 27, the vertical section of the frame body 28 is T-shaped, the proximal ends of the two second springs 29 are fixed on the two sides of the frame body 28, the distal ends of the two second springs 29 are fixed on the inner walls of the two ends of the frame groove 27, the outer surface of the stabilizing block 23 is slidingly connected with the inner wall of the stabilizing groove 16, the horizontal section of the stabilizing block 23 is cross-shaped, the stabilizing groove 16 is penetrated in the upper middle part of the sliding block 15, the lower ends of the two supporting rods 25 are fixed on the two sides of the stabilizing groove 16, the outer surfaces of the two supporting rods 25 are slidingly connected with the inner walls of the two recesses 24, the vertical sections of the two supporting rods 25 are T-shaped, the lower ends of the two first springs 26 are fixed on the upper ends of the two supporting rods 25, the upper ends of the two first springs 26 are fixed on the upper end inner walls of the two recesses 24, the outer surface of the sliding block 15 is slidingly connected with the inner wall of the sliding groove 8, the upper surface of the sliding block 15 is in contact with the lower surface of the supporting frame 17, the horizontal section of the supporting frame 17 is T-shaped, the two negative ion generators 18 are oppositely arranged, the two limiting grooves 22 are penetrated in the two sides of the supporting frame 17, the upper ends of the two temperature-sensitive magnetic steels 19 are fixed on the lower surfaces of the two negative ion generators 18, the outer surfaces of the two temperature-sensitive magnetic steels 19 are arranged on the upper end openings of the two limiting grooves 22, the lower surfaces of the two temperature-sensitive magnetic steels 19 are in contact with the upper surfaces of the two permanent magnets 20, the middle parts of the two permanent magnets 20 are fixed on the upper ends of the two extrusion frames 21, the outer surfaces of the two extrusion frames 21 are slidingly connected with the inner walls of the two limiting grooves 22, the lower surfaces of the two extrusion frames 21 are in contact with the upper surface of the stabilizing block 23, and the middle part of the stabilizing block 23 is protruding, as shown in Figure 1 Figure 11

[0022] The specific implementation process is as follows: the high temperature generated by the negative ion generator 18 is conducted to the temperature-sensitive magnetic steel 19, the temperature-sensitive magnetic steel 19 loses magnetism after being heated and is separated from the permanent magnet 20. Under the action of gravity, the permanent magnet 20 moves downward along the limiting groove 22, and simultaneously drives the extrusion frame 21 fixed in the middle to move downward synchronously, and finally falls on the stabilizing block 23 below. In cooperation with the extrusion frame 21 which has fallen on the stabilizing block 23 before, the two extrusion frames 21 all fall on the stabilizing block 23, and the stabilizing block 23 moves downward along the stabilizing groove 16 in the middle of the sliding block 15 under the joint action of the gravity of the two extrusion frames 21 and the two permanent magnets 20. In the process of moving downward, the stabilizing block 23 is supported by the supporting rod 25 fixed on the two sides of the stabilizing groove 16, and the first spring 26 is compressed, and the frame groove 27 is driven to move downward by the limiting action of the middle part, and the frame body 28 drives the driving rod 30 fixed on the lower end to slide on the surface of the driving frame 13; ​​When the driving motor 10 drives the fixed rod 11 to rotate, the fixed rod 11 will drive the driving frame 13 fixed at the upper end to rotate synchronously. At this time, the driving rod 30 on the upper surface of the driving frame 13 will fall into the driving groove 14 in the middle part, and the rotating driving frame 13 will extrude the driving rod 30 through the driving groove 14, so that the driving rod 30 drives the frame body 28 fixed at the upper end to slide along the sliding groove 8 under the cooperation of the inner wall of the frame groove 27 of the stabilizing block 23 and the two fixed second springs 29. When the sliding block 15 slides to the other side, the protruding part in the middle of the stabilizing block 23 will move to the lower surface of the other extrusion frame 21, so as to drive the extrusion frame 21 to drive the permanent magnet 20 fixed at the upper end to contact the temperature-sensitive magnetic steel 19 which is in the cooling process. At this time, the magnetism of the permanent magnet 20 is transmitted to the temperature-sensitive magnetic steel 19, and the two are connected by magnetic adsorption. The extrusion force of the extrusion frame 21 on the stabilizing block 23 disappears instantaneously, and the first spring 26 which is compressed drives the stabilizing block 23 to move upward, and the driving rod 30 synchronously slides out of the driving groove 14 of the driving frame 13, thereby realizing the effect of dynamically adjusting the air duct. Under the control of the PLC in the shell 1, when the heating negative ion generator 18 stops working, the air duct will automatically shift to the side of the other negative ion generator 18, effectively avoiding the problems of sudden drop in purification efficiency, increase in running noise, and even complete stop caused by continuous operation of a single generator, thereby improving the use effect of the purification device.

[0023] Example two: When a single generator is continuously operated for a long time, the internal core components will continuously accumulate heat due to the energy conversion process, which will cause the overall temperature of the equipment to continuously rise. This high-temperature environment not only accelerates the aging speed of the components, but also may cause potential faults such as insulation performance decline and circuit short circuit, and in severe cases, the core module may be burned out, directly affecting the stable operation of the entire purification system. Therefore, it is necessary to quickly cool the generator generating high temperature during work, so as to prolong the service life of the purification device.

[0024] Please refer to Figure 1 - Figure 11 As shown in FIG. 1, the function of efficient cooling is added on the basis of example one; Please refer to Figure 1 - Figure 11 As shown in FIG. 1, the first through hole 31 is formed on both sides of the support frame 17, the second through hole 32 is formed on both sides of the sliding block 15, the two second through holes 32 penetrate the two sides of the sliding block 15, the two first through holes 31 penetrate the two sides of the support frame 17, the two first through holes 31 are oppositely arranged, and each first through hole 31 is V-shaped.

[0025] The specific implementation process is as follows: the high temperature generated by the negative ion generator 18 is conducted to the temperature-sensitive magnetic steel 19. As the temperature gradually rises, the temperature-sensitive magnetic steel 19 will change its physical state due to the thermal induction characteristics, thereby driving the extrusion frame 21 to move. In this process, the extrusion frame 21 cooperates with the stabilizing block 23 to smoothly slide the sliding block 15 along the preset trajectory by driving the transmission of the driving frame 13. When the sliding block 15 slides to a specific position, the second through hole 32 formed on the surface of the sliding block 15 will be precisely connected with the first through hole 31 of the corresponding component, and an complete heat dissipation channel is formed at once. At this time, the high temperature accumulated in the negative ion generator 18 which stops working can be quickly dissipated outward through the channel, achieving the effect of efficient cooling. This dynamic cooling mechanism can timely suppress the temperature rise of the equipment, effectively avoid the problems of internal component aging, performance degradation, and even burning caused by continuous high temperature, and thus achieve the effect of prolonging the service life of the purification device.

[0026] In the process of purifying the air by the purification device, the guide plate 35 needs to be adjusted in angle by a specific drive to ensure that the airflow flows efficiently along the preset path. In the current design scheme, an independent power source needs to be additionally provided to provide driving force for the guide plate 35, which not only increases the number of internal components of the device, but also increases the complexity of the overall structure. From the cost point of view, the purchase, installation and subsequent maintenance of the additional power source will directly increase the initial cost of the purification device; at the same time, the energy consumption generated by the operation of the independent power source will also significantly increase the long-term use cost of the device. Therefore, it is particularly necessary to explore a scheme for controlling the guide plate 35 by relying on the original power system of the purification device. Through reasonable transmission structure design, the existing power of the device is utilized, which can not only realize precise control of the guide plate 35, but also save the investment of additional power source, thereby reducing the cost of the purification device while reducing the energy consumption expenditure in daily operation, effectively reducing the use cost.

[0027] Please refer to Figure 1 - Figure 11 As shown in FIG. 1, the automatic adjustment function is added on the basis of the embodiment one. Please refer to Figure 1 - Figure 11 Figure 1 Figure 11As shown, the upper end of the shell 1 is detachably installed with the upper cover 33 through bolts, the middle part of the upper cover 33 is fixed with a plurality of connecting rods 34, the outer surfaces of the plurality of connecting rods 34 are all rotationally connected with the flow guides 35, the middle parts of the plurality of flow guides 35 are rotationally connected with the connecting blocks 36, the upper ends of the two sides of the sliding block 15 are both fixed with the fixed blocks 37, the two ends of the plurality of connecting rods 34 are fixed in the middle part of the upper cover 33, the outer surfaces of each connecting rod 34 are rotationally connected in the middle part of each flow guide 35, the middle part of the connecting block 36 is rotationally connected in the middle part of the lower end of the plurality of flow guides 35, the vertical section of the connecting block 36 is T-shaped, the lower ends of the two fixed blocks 37 are fixed in the two sides of the sliding block 15, and the vertical sections of each fixed block 37 are all L-shaped, and the outer surfaces of the two fixed blocks 37 are in contact with the outer surfaces of the connecting blocks 36.

[0028] The specific implementation process is as follows: the high temperature generated by the negative ion generator 18 is conducted to the temperature-sensitive magnetic steel 19, as the temperature gradually rises, the temperature-sensitive magnetic steel 19 will change the physical state due to the thermal induction characteristics, and then drive the extrusion frame 21 to move. In this process, the extrusion frame 21 cooperates with the stabilizing block 23, and by the transmission of the driving frame 13, the sliding block 15 is pushed to slide smoothly along the preset track; So that when the sliding block 15 slides, the two fixed blocks 37 fixed on the upper ends of the two sides will move synchronously, the moving fixed blocks 37 extrude the connecting blocks 36, so as to drive the connecting blocks 36 to drive the flow guides 35 to complete the angle adjustment operation under the support of the connecting rods 34, realize the effect of automatic adjustment, without the need of additional power source for driving, and the purchase and maintenance cost of the independent power device is saved from the structural design, so as to reduce the cost of the purification device and the use cost.
