Description

Technical Field

[0001] The present application relates to the field of air purification equipment, and in particular to an electrostatic air purifier. Background Art

[0002] The core components of an electrostatic air purifier are an electrostatic generator and a particle collector. The electrostatic generator ionizes the air through high voltage, so that the particles in the air carry positive charges, while the particle collector is usually connected to negative high voltage electricity, so that a negative high voltage electric field is formed inside the particle collector. When the positively charged particles flow through the negative high voltage electric field with the air, the particles are adsorbed in the collector, thereby achieving the effect of purifying the air.

[0003] Generally, the electrostatic generator needs to be connected to a positive DC high voltage of 10-20kv, and the particle collection device usually needs to be connected to a negative DC high voltage of 2-10kv. Due to the working nature of the electrostatic air purifier, after working for a period of time, the electrostatic generator and collection device will need to be disassembled, cleaned, maintained or replaced due to the accumulation of particles.

[0047] The present application provides an electrostatic air purifier, such as Figures 1 to 16 As shown, the electrostatic air purifier includes a housing 1, a high-voltage circuit control module 2, an electrostatic generating module 3 and a collecting module 4, and the high-voltage circuit control module 2 is fixed on the outer wall of the housing 1; three fixing holes are provided on the housing 1, and the high-voltage circuit control module 2 includes three conductive components 6, and the three conductive components 6 extend into the interior of the housing 1 from the fixing holes respectively, and the conductive components 6 are sleeved with an insulating sleeve 91, and the insulating sleeve 91 abuts against the hole wall of the fixing hole, one of the conductive components 6 is connected to the electrostatic generating module 3, and the other two conductive components 6 are connected to the collecting module 4. In the electrostatic air purifier of the present application, three fixing holes are provided on the housing 1, and the high-voltage circuit control module 2 is connected to the electrostatic generating module 3 and the collecting module 4 inside the housing 1 through the three conductive components 6, and the conductive components 6 are sleeved with an insulating sleeve 91, and the insulating sleeve 91 abuts against the hole wall of the fixing hole, so as to achieve the isolation between the housing 1 and the conductive components 6. In this way, the formation of electric spark patterns in the housing 1 caused by leakage of the conductive component 6 is avoided, thereby avoiding the short circuit problem caused by the high voltage breakdown of the housing 1.

[0048] In addition, the conductive component 6 extends into the interior of the housing 1 and is connected to the static electricity generating module 3 and the collecting module 4, which can avoid rust and aging problems caused by the conductive component 6 being exposed.

[0049] In the embodiments of the present application, Figure 2As shown, the housing 1 includes a first fixing plate 11, a second fixing plate 12, a third fixing plate 13 and a fourth fixing plate 14, the first fixing plate 11 is parallel to the second fixing plate 12, and the third fixing plate 13 is parallel to the fourth fixing plate 14. The first fixing plate 11, the third fixing plate 13, the second fixing plate 12 and the fourth fixing plate 14 are connected in sequence, the high-voltage circuit control module 2 is fixed on the outer side wall of the first fixing plate 11 facing away from the second fixing plate 12, and the three conductive components 6 extend into the interior of the housing 1 through the first fixing plate 11 to facilitate connection with the static electricity generating module 3 and the collecting module 4. An opening 121 is provided on the second fixing plate 12, so that the static electricity generating module 3 and the collecting module 4 can be fixed to the interior of the housing 1 through the opening 121. A door body is provided on the opening 121, and the door body is detachably connected to the opening 121. The third fixing plate 13 is provided with a first fixing bar 15, a second fixing bar 16 and a third fixing bar 17 on one side facing the fourth fixing plate 14, and the fourth fixing plate 14 is also provided with a first fixing bar 15, a second fixing bar 16 and a third fixing bar 17 on one side facing the third fixing plate 13. When installing the static electricity generating module 3, the lower end of the static electricity generating module 3 is abutted against the two first fixing bars 15, and the upper end of the static electricity generating module 3 is abutted against the two second fixing bars 16, and then the static electricity generating module 3 is pushed to slide until the static electricity generating module 3 is connected to a conductive component 6, thereby fixing the static electricity generating module 3.

In this way, the connection between the static electricity generating module 3 and the collecting module 4 and the conductive needle 61 can be achieved by pushing the static electricity generating module 3 and the collecting module 4, thereby improving the convenience of installing the static electricity generating module 3 and the collecting module 4.

[0050] Furthermore, the bottom of the shell 1 has an air inlet, the top of the shell 1 has an air outlet, and a fan 5 is provided on the top of the shell 1. The electrostatic air purifier is generally installed through a support frame so that the bottom of the electrostatic air purifier is suspended. Driven by the fan 5, air flows into the interior of the shell 1 from the air inlet at the bottom, and the particles are positively charged when passing through the high-voltage electric field formed by the electrostatic generating module 3. When flowing through the negative electric field formed by the collecting device, the particles are adsorbed into the interior of the collecting device, and then the air flows out from the air outlet, forming an air purification effect.

[0051] like Fig.14As shown, the high-voltage circuit control module 2 includes a positive DC high-voltage output terminal 21, a negative DC high-voltage output terminal 22 and a ground output terminal 23. The positive DC high-voltage output terminal 21, the negative DC high-voltage output terminal 22 and the ground output terminal 23 are respectively connected to three conductive needles 61. The conductive needle 61 connected to the positive DC high-voltage output terminal 21 is connected to the static electricity generating module 3, and the conductive needle 61 connected to the negative DC high-voltage output terminal 22 and the conductive needle 61 connected to the ground output terminal 23 are connected to the collection module 4.

[0052] In the embodiments of the present application, Figures 12 to 17 As shown, the conductive component 6 includes a conductive pin 61, a terminal and a rubber-coated portion 63. The end of the conductive pin 61 has a thread. One end of the terminal is connected to the high-voltage circuit control module 2 through a cable 62. The other end of the terminal is provided with a threaded countersunk hole to facilitate the connection between the terminal and the conductive pin 61. The terminal and the cable 62 can be molded together by rubber coating, and the rubber coating is cured to form the rubber-coated portion 63. By providing the rubber-coated portion 63, it is possible to avoid the sharp parts on the conductive pin 61 from discharging under high voltage, which can greatly improve the insulation and reliability of the conductive pin 61 and prevent the problem of high-voltage static leakage and creepage.

[0053] Preferably, the rubber-coated portion 63 may be made of PVC (Polyvinyl chloride) or Teflon through rubber-coated injection molding. The rubber-coated portion 63 formed in this way has good waterproof and dustproof effects.

[0054] like Fig.17 As shown, the terminal block may include a first hole and a second hole, the first hole and the second hole are respectively recessed from two surfaces of the terminal block that are opposite to each other to the inside of the terminal block, and a thread is provided on the hole wall of the first hole, so as to realize the connection between the terminal block and the conductive pin 61. The terminal block and the conductive pin 61 are threadedly connected, which can facilitate the replacement of the conductive pin 61. The cable 62 is inserted into the second hole, so as to realize the connection between the cable 62 and the terminal block. The rubber-coated part 63 covers the entire terminal block and part of the conductive pin 61, and the insulating sleeve 91 is sleeved on the outside of the rubber-coated part 63, and part of the conductive pin 61 is also covered on the outside of the insulating sleeve 91. Through the cooperation of the insulating sleeve 91 and the rubber-coated part 63, the conductive pin 61 will not be exposed except for the part used to connect with the connector 8 described below, which further improves the insulation of the conductive pin 61.

[0055] In addition, the outside of the cable 62 is provided with a heat shrink tube 65, which is sleeved on the outside of the cable 62, with part of the heat shrink tube 65 located inside the rubber coating portion 63, and the other part of the heat shrink tube 65 exposed outside the rubber coating portion 63. The heat shrink tube 65 is used to insulate the cable 62, and the heat shrink tube 65 has a higher adhesion to the rubber coating portion 63, which can avoid the appearance of a gap between the rubber coating portion 63 and the cable 62, thereby improving the insulation of the connection between the cable 62 and the wiring component.

[0056] Furthermore, the three cables 62 are respectively connected to the positive DC high voltage output terminal 21 , the negative DC high voltage output terminal 22 and the ground output terminal 23 , thereby realizing the connection between the three conductive needles 61 and the positive DC high voltage output terminal 21 , the negative DC high voltage output terminal 22 and the ground output terminal 23 .

[0057] like Fig.13 , Fig.14 and Fig.15 As shown, three mounting members 18 are arranged on the outer wall of the first fixed plate 11, and the three mounting members 18 correspond to the three fixing holes respectively. The mounting members 18 surround a limiting cavity, and the limiting cavity is connected to the corresponding fixing hole. Each mounting member 18 is correspondingly provided with two fixing columns 19, and the conductive component 6 also includes a fixing cover 64.

The axis of the limiting cavity coincides with the axis of the conductive component 6. By setting the mounting member 18, the installation accuracy of the conductive component 6 can be improved. At the same time, by setting the fixing cover 64, the conductive component 6 is completely sealed in the mounting member 18, which can effectively prevent the conductive needle 61 from leaking, discharging and creeping on the first fixed plate 11, thereby improving the stability of the operation of the electrostatic air purifier.

[0058] In the embodiments of the present application, Figure 3 As shown, the electrostatic air purifier further includes an insulating pad 7, one side of the insulating pad 7 is in contact with the inner side wall of the first fixed plate 11, and the other side of the insulating pad 7 is in contact with the static electricity generating module 3 and the collecting module 4 respectively, and the three conductive components 6 all pass through the insulating pad 7, so as to facilitate the connection of the three conductive components 6 with the static electricity generating module 3 and the collecting module 4. The conductive component 6 located between the first fixed plate 11 and the static electricity generating module 3 and the conductive component 6 located between the first fixed plate 11 and the collecting module 4 are insulated by the insulating pad 7, which can effectively prevent the overflow of high-voltage static electricity and the occurrence of creepage when the electrostatic air purifier is working.

[0059] Furthermore, the collection module 4 includes a collection component and a grounding component, and the electrostatic air purifier also includes three connectors 8. The collection component, the grounding component and the electrostatic generating module 3 are respectively connected to the three conductive components 6 through the three connectors 8, and the three connectors 8 are all located on the side of the insulating pad 7 facing away from the housing 1. The three connectors 8 can be separated from the first fixing plate 11 by the insulating pad 7, so that the overflow of high-voltage static electricity can be avoided.

[0060] Optionally, the insulating pad 7 includes a main body 71, a first partition 72, a second partition 73, and a third partition 74. The main body 71 is in the shape of a plate, and the first partition 72, the second partition 73, and the third partition 74 are in the shape of a block. The first partition 72 and the second partition 73 are respectively connected to the two ends of the main body 71, and the third partition 74 is located in the middle of the main body 71. When the static electricity generating module 3 and the collecting module 4 are respectively connected to the three conductive needles 61, the static electricity generating module 3 is located between the first partition 72 and the third partition 74, and the collecting module 4 is located between the second partition 73 and the third partition 74.

[0061] In addition, the electrostatic air purifier further includes two insulating plates 92, which are respectively attached to the third fixing plate 13 and the fourth fixing plate 14, so as to achieve insulation between the electrostatic generating module 3 and the collecting module 4 and the third fixing plate 13 and the fourth fixing plate 14. Optionally, the two insulating plates 92 can be integrally formed with the insulating pad 7.

[0063] Furthermore, if Figure 4 As shown, the collecting assembly further includes a first side plate 45, a second side plate 46, a top frame 47 and a base 48. The base 48 and the top frame 47 are located at the ends of the whole formed by the collecting plate 41 and the grounding plate 43. The two ends of the collecting plate 41 are supported by the top frame 47 and the base 48 respectively, and the two ends of the grounding plate 43 are supported by the top frame 47 and the base 48 respectively. In this way, the grounding plate 43 and the collecting plate 41 are fixed by the top frame 47 and the base 48. The top frame 47 has a first fixing cavity 471 and a second fixing cavity 472. The connector 8 connected to the grounding assembly passes through the first fixing cavity 471 and is connected to the conductive component 6 connected to the grounding output terminal 23. The connector 8 connected to the collecting assembly passes through the second fixing cavity 472 and is connected to the conductive component 6 of the negative DC high voltage output terminal 22.
