Description

Technical Field

[0002] There are various types of negative ion generators. Its basic principle is to ionize the molecules in the air by using high-voltage electricity to form negative ions with negative charges.

In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0032] Combined with Figure 1 and Figure 2As shown in the figure, the present utility model provides a negative ion generator, which specifically includes an insulating partition 1, a first electrode plate 2, a second electrode plate 3, a protective upper cover 4 and a protective lower cover 5. The first electrode plate 2 and the second electrode plate 3 are respectively located on the upper and lower sides of the insulating partition 1. The protective upper cover 4 is detachably connected to the upper side of the insulating partition 1 to fix the first electrode plate 2 on the upper side of the insulating partition 1. A first limiting seat 12 is provided on the lower side of the insulating partition 1. The upper end of the second electrode plate 3 is detachably connected to the first limiting seat 12, and the lower end of the second electrode plate 3 abuts against the protective lower cover 5. The protective lower cover 5 is detachably connected to the lower side of the insulating partition 1, so that the second electrode plate 3 is limited and assembled between the lower side of the insulating partition 1 and the protective lower cover 5.

[0033] Among them, the first electrode plate 2 is connected to the high voltage of an external power supply, and the second electrode plate 3 is connected to the DC positive low voltage or grounded of the external power supply. A high-voltage electric field is formed between the first electrode plate 2 and the second electrode plate 3 to ionize the air to generate negative ions.

[0034] In the present utility model, the first electrode 2 and the second electrode plate 3 are respectively assembled on the upper and lower sides of the insulating partition 1, and the protective upper cover 4 and the protective lower cover 5 are respectively used to limit and fix the first electrode 2 and the second electrode plate 3. Moreover, the upper end of the second electrode 2 is assembled and positioned by the first limiting seat 12 on the lower side of the insulating partition 1. Then, when the protective lower cover 5 is detachably connected to the lower side of the insulating partition 1, the lower end of the second electrode 2 is abutted and limited, so as to facilitate the rapid assembly of the second electrode 2, and it is convenient to regularly disassemble the protective lower cover 5 during use and then remove the second electrode 2 to clean the adsorbed dust, reduce the shielding on the surface of the second electrode 2, and thus is beneficial to improving the negative ion generation efficiency of the negative ion generator.

[0035] The insulating partition 1 is provided with a plurality of first through holes 11. The first electrode plate 2 has a plurality of discharge ends 231 extending into the first through holes 11. The protective upper cover 4 is provided with a plurality of first air-permeable grooves 41. The protective lower cover 5 is provided with a plurality of second air-permeable grooves 51. The second electrode plate 3 is provided with a plurality of purification grooves 30 corresponding to the first through holes 11.

[0036] When the first air-permeable grooves 41, the first through holes 11, the purification grooves 30 and the second air-permeable grooves 51 are all arranged in one-to-one correspondence, that is, when the first air-permeable grooves 41, the first through holes 11, the purification grooves 30 and the second air-permeable grooves 51 are all on a straight-line channel, the air permeability is smooth, which is convenient for quickly taking out the negative ions generated by ionizing the air between the first electrode plate 2 and the second electrode plate 3, so that the negative ion generator can be in a better working state.

[0037] There are multiple first limit seats 12, and the first limit seats 12 are arranged on the connecting arms between multiple adjacent first through holes 11, so that the first limit seats 12 will not block the first through holes 11, which is conducive to ensuring that the negative ion generator is in a better working state.

[0038] In some preferred embodiments, see Figure 1 and Figure 4 As shown, a second limiting seat 52 is provided on the upper side of the protective lower cover 5, and the lower end of the second electrode plate 3 is detachably connected to the second limiting seat 52. That is, the upper end of the second electrode plate 3 is positioned by the first limiting seat 12, and the lower end of the second electrode plate 3 is positioned by the second limiting seat 52 on the upper side of the protective lower cover 5, and when the protective lower cover 5 is assembled to the insulating partition 1, the second electrode plate 3 is fixedly assembled between the insulating partition 1 and the protective lower cover 5.

[0039] In some preferred embodiments, the first limiting seat 12 and the second limiting seat 52 are both plug-in seats, so that the end of the second electrode plate 3 can be inserted into the plug-in seat, thereby simplifying the positioning and assembly operations and facilitating the disassembly and assembly of the second electrode plate 3.

[0040] The second electrode plate 3 can cooperate with the first electrode 2 to generate a high-voltage electric field to ionize the air. At the same time, the second electrode plate 3 generates static electricity when it is grounded or connected to a DC low voltage, which adsorbs dust particles with negative ions in the air, reduces floating dust particles in the air, and enhances the air purification efficiency of the negative ion generator.

[0041] A plurality of purification slots 30 are arranged on the second electrode plate 3 so that the second electrode plate 3 has a larger electrostatic adsorption surface area, which is beneficial to improving the adsorption performance of the second electrode plate 3 on dust particles floating in the air.

[0042] The purification tanks 30 of the second electrode plate 3 can be arranged in different shapes as needed. For example, the purification tanks 30 of the second electrode plate 3 can be arranged in a strip grid shape, a square grid shape, a circular grid shape, an elliptical grid shape or a honeycomb shape.

[0043] In some preferred embodiments, the plurality of purification tanks 30 of the second electrode plate 3 are arranged in a strip grid shape as an example. Figure 6 As shown, the second electrode plate 3 includes a plurality of first conductive sheets 31 arranged side by side and evenly spaced, and a long strip purification tank 30 is formed between any two adjacent first conductive sheets 31. At this time, the plurality of parallel purification tanks 30 of the second electrode plate 3 are arranged in a strip grid shape, and any long strip purification tank 30 corresponds to a plurality of first through holes 11 arranged in a straight line directly above it.

[0044] In some preferred embodiments, the plurality of purification tanks 30 of the second electrode plate 3 are arranged in a square grid shape as an example. Figure 6As shown, the second electrode plate 3 includes a plurality of first conductive sheets 31 arranged side by side at uniform intervals in a first direction and a plurality of second conductive sheets 32 arranged side by side at uniform intervals in a second direction. The first direction is orthogonal to the second direction. Each first conductive sheet 31 is connected to a plurality of second conductive sheets 32. Any two adjacent first conductive sheets 31 and any two adjacent second conductive sheets 32 enclose a square purification tank 30.

[0045] To facilitate the assembly of the plurality of first conductive sheets 31 and the plurality of second conductive sheets 32 into the second electrode plate 3, a first slot 311 with an opening facing downward is provided at the lower end of the first conductive sheet 31, and a second slot 321 with an opening facing upward is provided at the upper end of the second conductive sheet 32. The first slot 311 of the first conductive sheet 31 is inserted and connected to the second slot 321 of the second conductive sheet 32, thereby achieving rapid assembly, as shown in Figure 6 shown.

[0046] As shown in Figure 5 , Figure 7 and Figure 8 shown, the first electrode plate 2 includes a plurality of conductive strips 21 arranged at uniform intervals and connecting strips 22 that fixedly connect the plurality of conductive strips 21. A plurality of discharge parts 33 are evenly spaced on each conductive strip 21. At both ends of each discharge part 33, there are discharge ends 231 extending toward the first through holes 11 of the insulating partition 1.

[0047] Among them, the lengths of each discharge end 231 are equal, and it is preferably that each discharge end 231 respectively passes downward through one of the first through holes 11 and extends out of the lower side of the insulating partition 1. Since the discharge part of the discharge end 231 is mainly concentrated at its lower tip, when the discharge end 231 extends downward out of the lower side of the insulating partition 1, the lower tip of the discharge end 231 will not be blocked by the hole side wall of the first through hole 11, which is beneficial to enabling each discharge end 231 to achieve the best discharge efficiency, so that the negative ion generator is in a better working state.

[0048] On the conductive strip 21 or / and the connecting strip 22, a plurality of second fixing holes 24 are provided; on the upper side of the insulating partition 1, a plurality of limiting posts are provided, and each limiting post passes through one of the second fixing holes 24 to quickly position and assemble the first electrode 2 on the upper side of the insulating partition 1.

[0049] In addition, the protective upper cover 4 and the protective lower cover 5 can respectively be detachably connected to the insulating partition 1 by any existing detachable structure.

[0050] For example, a plurality of first buckles 42 are provided on the periphery of the protective upper cover 4, and the protective upper cover 4 is buckled and connected to the insulating partition 1 by the first buckles 42; a plurality of second buckles 53 are provided on the periphery of the protective lower cover 5, and the protective lower cover 5 is buckled and connected to the insulating partition 1 by the second buckles 52.

[0051] In order to make the fixation of the lower protective cover 5 and the insulating partition 1 more firm, and to prevent the lower protective cover 5 from loosening, which may cause changes in the relative position parameters between the first electrode plate 2 and the second electrode plate 3 and affect the working performance of the negative ion generator, a plurality of studs 13 are provided on the lower side of the insulating partition 1, and a plurality of screw holes 54 are correspondingly provided on the lower protective cover 5. Screws are used to pass through the screw holes 54 and engage with the studs 13 to lock the lower protective cover 5 and the insulating partition 1 together.

[0052] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
