Specifically, insulator mounting holes 204 are respectively opened at the front side wall of the electric control box body 202 corresponding to the first spring 31 and the second spring 32 of the power-on spring 3, and four second insulators are fixed through the mounting holes by plastic insulating bolts, and the center of the second insulator has a conductive screw connected to the positive and negative poles of the power supply 203, respectively, and the voltage is transmitted to the conductive metal sheet near the side of the electric control box 200 through the second insulator, and the free ends of the first spring 31 and the second spring 32 are respectively connected to the corresponding high-voltage end and low-voltage end in a touch manner. The high voltage and the low voltage of the grounding wire are insulated by insulators.

It should be noted that the "U"-shaped structural member 2 can be single-layer or multi-layer. It should be noted that the multi-layer structure is provided with structures of different materials such as filter cotton or filter fiber on the right or left side of the "U"-shaped structural member 2 for filtering. It is also possible to set filter cotton or filter fiber between the double-layer "U"-shaped structural member 2 to achieve a better filtering effect.

[0066] It should also be noted that the blocking plate 21 can be any one of a straight-line, “V”-shaped, wavy or arc-shaped plate-shaped structure.

[0067] In addition, when only one "U"-shaped structural member 2 is installed in the electric field frame body 1, the sealing plate 21 can be directly connected to the grounded conductive frame 11 to form a "U"-shaped structural member 2 with the grounded conductive frames 11 on both sides, saving the first baffle plate 22 and the second baffle plate 23 and the connecting plate 24, thereby reducing costs.

In the present embodiment, the through holes 211 are provided on the three plates of the blocking plate 21, the first baffle plate 22 and the second baffle plate 23. When the airflow passes through the through holes 211 on the three plates of the blocking plate 21, the first baffle plate 22 and the second baffle plate 23, the three plates of the blocking plate 21, the first baffle plate 22 and the second baffle plate 23 can achieve the dual effect of electrostatic adsorption and filtration of particulate matter. Of course, some through holes 211 can also be provided on the blocking plate 21, the first baffle plate 22 or the second baffle plate 23. And the through holes 211 on the blocking plate 21, the first baffle plate 22 and the second baffle plate 23 are of the same size, mainly to evenly distribute the airflow, which is conducive to improving the capture efficiency of particulate matter. At the same time, the purpose of setting the through hole 211 on the first baffle 22 and the second baffle 23 is to increase the flow path of the smoke and extend the flow time of the smoke, thereby ensuring a better adsorption effect. Furthermore, the angle between the first baffle 22 and the second baffle 23 and the blocking plate 21 is between 95° and 115°. The purpose of setting at a certain angle is to cooperate with the cleaning method of the cleaning unit 301 to clean the dead corner, thereby achieving better cleaning effect, simple design and low cost. Of course, the angle between the two baffles and the blocking plate 21 can also be set to 90° here, and the cleaning effect can be ensured by using a nozzle with a rotating function.

[0069] Further, the discharge electrode is connected to the high-voltage conductive connecting rod 14 through a limiting structure. Specifically, the limiting member is used to control the axial position of multiple linear high-voltage electrodes 4 on the high-voltage conductive connecting rod 14. In this embodiment, the limiting member can be a groove arranged along the axial interval of the high-voltage conductive connecting rod 14, and the two ends of the linear high-voltage electrode 4 are set with spring hooks and clamped in the groove for axial limiting. Of course, it can also be set as an aluminum tube set on the high-voltage conductive connecting rod 14, and an annular groove for limiting the axial position of the linear high-voltage electrode 4 is formed between adjacent aluminum tubes. The first baffle and the second baffle of the "U"-shaped structural member 2 are fixed to the grounding conductive connecting rod 15 through the aluminum tube. The aluminum tube plays a limiting role (not shown in the figure). The discharge electrode is composed of a group of linear high-voltage electrodes 4 arranged in parallel at equal intervals and hung on the high-voltage conductive connecting rod 14. A high-voltage direct current is passed to form a high-voltage electric field to charge the particles in the airflow. Of course, a fixing groove can also be opened on the high-voltage conductive connecting rod 14 to fix the linear high-voltage electrode 4. The dust collecting electrode is composed of a "U"-shaped structural member 2 and two grounded conductive connecting rods 15. The right side of the "U"-shaped structural member 2 is connected to the mounting assembly. Specifically, the mounting assembly is two welding plates, that is, the "U"-shaped structural member 2 is welded with the two welding plates. The grounded conductive connecting rod 15 passes through the two welding plates on the rear side wall of the blocking plate 21 of the "U"-shaped structural member 2. There is an aluminum tube between the grounded conductive connecting rod 15 and the "U"-shaped structural member 2 to achieve the effect of isolation and fixation, and at the same time ensure that the "U"-shaped structural member 2 is distributed in parallel with equal spacing on the grounded conductive connecting rod 15. Therefore, the charged particles are captured by the "U"-shaped structural member 2 under the attraction, which has a good adsorption effect.

[0070] Furthermore, filters 500 are provided at both the air inlet 106 and the air outlet 107 .

[0071] In this embodiment, the cleaning mechanism 300 is arranged in the housing 100, and the cleaning mechanism 300 includes a plurality of cleaning units 301, and the cleaning units 301 are arranged one by one corresponding to the electrostatic dust removal electric field 400, and can respectively perform regular cleaning on the electrostatic dust removal electric field 400. Of course, the cleaning unit 301 can also be arranged between two adjacent electrostatic dust removal electric fields 400, and a plurality of atomizing nozzles 3013 are installed in both the left and right directions of the liquid distributing pipe 3012 of the cleaning unit 301, that is, cleaning can be performed from both sides of the electrostatic dust removal electric field 400, which greatly improves the cleaning effect.

[0072] Furthermore, the cleaning mechanism 300 includes an "L"-shaped liquid supply pipe 3011, and the lateral portion of the liquid supply pipe 3011 is arranged along the front to rear direction of the box body 100, and the vertical portion of the liquid supply pipe 3011 passes through the top wall 105 upward to communicate with the external box body containing cleaning liquid. The cleaning mechanism 300 also includes a plurality of liquid distribution pipes 3012 connected to the liquid supply pipe 3011, and the plurality of liquid distribution pipes 3012 are arranged on the liquid supply pipe 3011 at intervals. The liquid distribution pipes 3012 are arranged along the longitudinal direction of the "U"-shaped structural member 2 of the electrostatic precipitator field 400, and a plurality of atomizing nozzles 3013 are spaced apart on the outer wall of the liquid distribution pipe 3012 close to one side of the "U"-shaped structural member 2, and the atomizing nozzles 3013 can spray water toward the "U"-shaped structural member 2. Three atomizing nozzles 3013 are evenly distributed on each liquid distribution pipe 3012, which can achieve full coverage of the electric field and a more comprehensive cleaning effect.

[0073] It should be noted that one end of the liquid supply pipe 3011 is connected to a water pump, which extracts external cleaning liquid (the cleaning liquid is water in this embodiment), sends the water to the liquid distribution pipe 3012 through the liquid supply pipe 3011, and finally sprays it through the atomizing nozzle 3013 to spray and clean the electrostatic dust removal electric field 400. It is to be emphasized here that although the cleaning mechanism 300 sprays clean water, because this embodiment is cleaned regularly, this cleaning method can meet the subsequent demand for particle adsorption, and compared with the existing manual cleaning, it saves a lot of tasks and cleaning costs.

[0074] Furthermore, it also includes a track support 600 disposed on the inner side of the bottom wall 103 of the box body 100 and a sliding track 700 disposed on the track support 600. The track support 600 is arranged along the bottom wall 103 from front to back, the sliding track 700 is equal in length to the track support 600, and the bottom of the electric field frame body 1 of the electrostatic precipitator electric field 400 is slidably connected to the sliding track 700. The track support 600 is a U-shaped groove. The track support 600 is located on the upper end surface of the bottom wall 103 and the lower end surface of the top wall 105 of the box body 100, and the track support 600 on the upper and lower end surfaces are correspondingly arranged. The track support 600 is welded and fixed to the box body 100. The sliding track 700 is placed on the track support 600 and is arranged in parallel from the air inlet 106 to the air outlet 107, and is used to place the electrostatic dust removal field 400. Among them, four small tracks are formed between the sliding track 700 and the track support 600. The small track near the air inlet 106 and the air outlet 107 is used to place the filter net, the purpose is to prevent large foreign matter from entering the purifier with the air flow; the electrostatic dust removal field 400 is placed in the box body 100 from the front of the box body 100. By setting the sliding track 700, it can be ensured that the electrostatic dust removal field 400 and the filter net 500 will not shake or deviate, thereby ensuring the effect of adsorption and dust removal.

[0075] In this embodiment, the controller is arranged in the electric control box 200, and the controller is electrically connected to the electric control box 200, and is used to control the power supply of the electrostatic dust removal electric field 400. The controller is electrically connected to the water pump of the cleaning mechanism 300, and is used to control the cleaning of the electrostatic dust removal electric field 400. The controller can be composed of a plc or a single-chip microcomputer, and the controller can automatically control the power supply, fan and water pump of the electrostatic dust removal electric field 400. When the restaurant is closed at night, the controller cuts off the power supply of the electrostatic dust removal electric field 400, controls the water pump to open, and extracts water to self-clean the electric field through the spray cleaning device. After cleaning for 10 minutes (the cleaning time can be adjusted according to actual conditions), the spray cleaning device is turned off, and the controller automatically controls the fan to dry the electric field. The specific drying time is adjusted according to actual conditions to ensure that the insulating parts of the purifier are completely dry and do not affect subsequent use. Of course, in order to ensure the normal operation of the purifier during the day, this purifier is generally cleaned regularly at night.

[0076] It should be noted here that the cleaning liquid includes water, but is not limited to water. In order to improve the cleaning effect, the cleaning liquid can also be alkaline solution or steam to improve the cleaning effect.
