The present embodiment provides an electric field assembly and a purifier including the same, which treat oil smoke using an ionization principle. As shown in fig. 1, the purifier includes an electric control device 8 and a box 9, and a plurality of electric field assemblies 10 are sequentially arranged on a mounting rail 91 in the box 9. And the electric control device 8 is internally provided with structures such as a power supply, a control component and the like and is used for supplying power to the whole electric field assembly and controlling the operation of the electric field assembly. The electric control device 8 is connected to the electric field assemblies 10 located at the end portions, and the plurality of electric field assemblies 10 are in current conduction with each other, so that all the electric field assemblies 10 can receive power supply and control signals of the electric control device 8.

As shown in fig. 2 and 3, the electric field assembly includes a connecting rod 1, a splicing plug 2, a splicing base 3, a plurality of electric field plates 4 and an end plate 7, wherein the splicing plug 2 and the splicing base 3 are respectively connected to two ends of the connecting rod 1; the electric field pieces 4 arranged at intervals are respectively provided with through holes, and the connecting rod 1 is arranged in the through holes of the electric field pieces 4 in a penetrating way; the end plate 7 is arranged outside the field plate 4. As shown in fig. 5, the splice holder 3 includes a groove 31, and the electrical connection between the splice plug 2 and the splice holder 3 can be realized after the splice plug 2 is inserted into the groove 31.

By inserting the splicing plug 2 into the groove 31, the stable connection between the splicing plug 2 and the splicing base 3 is realized, the splicing plug 2 is prevented from accidentally shaking along the radial direction, the connection reliability is improved, and current can smoothly flow through the splicing plug 2 and the splicing base 3; splicing plug 2 is wrapped up in recess 31, has realized insulating isolation, does not need external insulating block, has reduced end plate 7's size, increases effective purification area, reduces the windage.

As shown in fig. 4 to 6, the splice base 3 includes a base body 32, and the groove 31 is disposed on the base body 32 and opens toward the outer side of the electric field assembly. For example, the splice base 3 is disposed at the right end of the connecting rod 1, and the groove 31 is opened toward the right end, so as to facilitate the splicing of the splice plug 2 disposed on the electric field assembly on the right side.

The splice plug 2 comprises a plug column 21, the top surface of the plug column 21 is abutted against the bottom surface of the groove 31, and the electrical conduction between the splice plug 2 and the splice base 3 is realized. Compared with a spring, the plug post 21 is more stable in shape, has no axial movement and no radial displacement, and the top surface of the plug post 21 is stably maintained in the state of abutting against the bottom surface of the groove 31 and is not easily separated.

In order to reduce the requirement for the machining accuracy, the convex points 5 are provided on one of the bottom surface of the groove 31 and the top surface of the plug post 21, and the concave portions 6 are provided on the other. In this structure, only need to make 5 blocks of bump in concave part 6 can realize splicing plug 2 and splicing base 3's stable connection, need not to process into complete smooth plane with the top surface of plug post 21 and the bottom surface of recess 31, machining efficiency is high, and the processing degree of difficulty is low.

In order to further prevent the splice plug 2 from moving in the radial direction, the side walls of the recess 31 are provided with a resilient member 33 and a contact 34 connected thereto, the resilient member 33 being configured to urge the contact 34 against the peripheral wall 22 of the plug column 21. In this configuration, the diameters of the plug post 21 and the groove 31 do not need to be designed and processed to have the same size, and the difference in diameter between the plug post 21 and the groove 31 is accommodated by the expansion and contraction of the elastic member 33, thereby reducing the requirement for the processing accuracy.

In addition to limiting the radial movement of the plug 21, the resilient member 33 and the contact 34 may also serve to prevent the plug 21 from being removed from the recess 31. To achieve this, the peripheral wall 22 is preferably curved or beveled, with the top surface of the plug post 21 having a diameter greater than the diameter of the middle portion of the plug post 21. During mounting, the peripheral wall 22 presses the elastic member 33 via the contact 34 during insertion of the plug post 21 into the recess 31. After being mounted in place, the elastic member 33 pushes the contact 34 toward the plug post 21 until the contact 34 abuts against the middle portion of the outer peripheral wall 22 (located in a range between both ends of the plug post 21, not specifically a point equidistant from both the head end and the tail end of the plug post 21). If the plug post 21 has a tendency to escape from the recess 31, the contacts 34 are stopped on the peripheral wall 22 closer to the top surface of the plug post 21. Unless the plug post 21 is pulled outward with a relatively large force, the outer peripheral wall 22 cannot press the contacts 34 radially outward, thereby preventing the plug post 21 from coming out of the recess 31.

In order to smoothly insert and remove the plug post 21 and the recess 31, the contact 34 has a spherical surface abutting against the outer peripheral wall 22. During the process of inserting the plug post 21 into the groove 31, the top surface of the plug post 21 can smoothly pass over the hemispherical contact 34, and the elastic member 33 is compressed by the contact 34, so that the plug post 21 is prevented from being blocked by some structures such as edges and the like from extending into the groove 31.

On the basis of the structure, the splicing plug 2 further comprises a connecting end 23 connected with the plug column 21, and the connecting end 23 is detachably connected to the end of the connecting rod 1. Detachably connected mode is convenient for change splicing plug 2, if splicing plug 2 damages need not to change connecting rod 1 in the lump, and it is more convenient to use, and is with low costs.

The concrete connection mode between plug post 21 and connecting rod 1 is not limited, and preferably, the periphery of link 23 is provided with the external screw thread, is provided with the internal thread on the end of connecting rod 1, and link 23 and the end threaded connection of connecting rod 1, the dismouting is efficient, and connection structure is more stable.
