Description

Technical Field

[0001] The invention relates to a ceiling-mounted wall-mounted high-concentration negative ion shielding device for preventing black walls, and belongs to the technical field of fresh air purification. Background Art

[0002] In the context of increasingly high requirements for ventilation and indoor environments. Based on the needs of fresh air purification and health, more and more ultra-high concentration negative ion devices have emerged. In particular, ultra-high concentration negative ion devices such as ceiling-mounted and wall-mounted types have emerged in the health industry. Because ceiling-mounted outlet negative ion devices and pure ceiling-mounted negative ion devices do not affect the wall space and indoor space layout, they have also been selected for more applications, but this must be matched with very high concentration negative ion devices, resulting in the formation of a radioactive black wall phenomenon at the negative ion emission end when the ultra-high concentration negative ion device's own corona field has a large enough influence. Especially in an environment where most ceilings are dominated by white ceilings, the appearance of this black ceiling will bring a very bad experience to customers. Because the ceiling or wall formed by the corona field is driven by a large number of electrons, a phenomenon of gradually deepening from the center point is formed. The ultra-fine dust in the air is quickly attached to the negative ion emission head by the force of the electron corona field, and the closer to the emission head, the darker it is. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a ceiling-mounted wall-mounted high-concentration negative ion shielding device for preventing black walls, which solves the problem of black walls appearing around the negative ion emission head. At the same time, the cost of regular maintenance and replacement of the device is greatly reduced, and it also plays a beautifying and decorative role.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0005] A ceiling-mounted and wall-mounted high-concentration negative ion shielding device for preventing black walls, comprising a mounting body and a negative ion device, and also comprising a protective film, a shielding metal ring and a conductive part;

[0007] The shielding metal ring is embedded in the inner wall of the protective film, and the shielding metal ring is arranged around the negative ion device, and the height of the bottom edge of the shielding metal ring is lower than the height of the emission head of the negative ion device;

[0008] The shielding metal ring is connected to a plurality of conductive parts, and the plurality of conductive parts are evenly distributed at the outer edge of the protective film, so as to reduce the secondary divergence effect of the corona formed by its own potential voltage.

[0009] As a preferred example, the conductive part includes a fixing piece and a ground wire, wherein the fixing piece is used to fix the protective film on the installation body, and the ground wire passes through the installation body and is electrically connected to the shielding metal ring.

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0032] like Figure 1 , Figure 2 and Figure 8 As shown, the ceiling-mounted wall-mounted high-concentration negative ion shielding device for preventing black walls includes a mounting body 1 and a negative ion device 2. The mounting body 1 is a structure for mounting negative ion devices on ceilings, walls, etc., and also includes a protective film 3, a shielding metal ring 4, and a conductive part;

[0033] The negative ion device 2 is arranged on the installation body 1, and the protective film 3 is sleeved on the negative ion device 2, and the protective film 3 and the installation body 1 are arranged closely, and the protective film 3 and the installation body 1 are isolated from air. In this way, there are not enough ultrafine particles to form a close-range strong electric potential driving effect with the installation body 1 and adhere to the installation body 1, forming a black halo and black wall phenomenon.

[0034] The shielding metal ring 4 can be a ring-shaped shielding ring formed by materials such as copper wire and iron wire, or it can be a shielding ring formed by a metal sheet. The shielding metal ring 4 is embedded in the inner wall of the protective film 3, and the shielding metal ring 4 is arranged around the negative ion device 2. The bottom edge of the shielding metal ring 4 is lower than the height of the emission head of the negative ion device 2. The metal part of the shielding metal ring 4 is also covered by the protective film 3 and does not contact a large amount of air in the outside space. Only a little air in the protective film 3 contacts the metal part. This greatly reduces the degree of dirtiness of the shielding cover metal ring 4. At the same time, the lower edge of the shielding metal ring 4 can prevent the electron rays directly formed by the spherical corona field emitted from the negative ion device 2 from directly affecting the installation body 1.

[0035] The shielding metal ring 4 is connected to a plurality of conductive parts, and the plurality of conductive parts are evenly distributed at the outer edge of the protective film 3, so as to reduce the secondary divergence effect of the corona formed by its own potential voltage.

[0036] The conductive part includes a fixing part 5 and a ground wire 6. The fixing part 5 should be made of non-conductive material, such as an insulating bolt or a silicone rod. The silicone rod can be designed to be three or four, so that the protective film 3 can be quickly fixed on the installation body 1. The ground wire 6 is a special ground wire, which is used to guide the free charge emitted by the negative ion device 2 received by the shielding metal ring 4 to avoid the formation of a concentrated effect. This ground wire 6 should be avoided from being connected to the same line as the power lines of other electrical appliances, or connected to the power lines and ground wires of other electrical appliances in a special way; the ground wire 6 passes through the installation body 1 and is electrically connected to the shielding metal ring 4. In the preferred embodiment, the ground wire 6 should pass through the fixing part 5 and be connected to the shielding metal ring 4 to reduce the number of openings.

[0037] The threading points of multiple fixings 5 ​​and multiple ground wires 6 are all located within the outer edge of the protective film 3, and are within the air isolation range, and are as far away from the position of the negative ion device 2 emitter head as possible. The importance here is to reduce the increase of the new corona field formed by the metal material of the shielding metal ring 4 as much as possible. Because the metal shielding material has a gathering effect, when continuously receiving free electrons, a new corona field will gradually be formed to form a high potential driving force of a new high voltage on the periphery, thereby forming a new effect of expanding the black wall range. Although it will no longer be as fast as the black wall speed caused by the original negative ion emitter head, as time goes by, the black wall effect will also be more obvious. When these shielding metal conductor materials are connected to the ground wire 6, the voltage level will be instantly reduced to a very low level, and the corona radiation field formed by the negative ion device 2 emitter head will also be changed to cause a truncation effect at the level of the installation body 1, so it will no longer directly act on the potential driving force formed by the installation body 1 contacting with the air, and the ultrafine particles in the air will be strongly gathered.

[0038] All shielding metal materials including the shielding metal ring 4 and the wires connected to the shielding metal ring 4 must maintain an effective and safe distance from the emitter of the negative ion device 2. This distance includes several levels. First, this distance cannot produce a direct arc discharge effect, because once an arc is formed, new hazards will be formed, including ozone and circuit instability caused by new excessive current, as well as the possibility of forming a fire point; second, this only plays a shielding role, not a mandatory role in reducing negative ions, so this safe distance must have enough space, just to minimize and eliminate the truncation of the linear corona field caused by the spherical emission of the emitter corona field to the installation body 1 level, but the negative ion formation mechanism of the emitter downward cannot be significantly weakened due to the close distance.

[0039] This safe distance is determined by combining the actual application of negative ion energy level and the design position of the emitter head. For example, when we use our own negative ion device, a 200 million level (Note: Shanghai Biaohui Technology Co., Ltd. corporate standard, the emitter head voltage is between -25kv and -30kv) emitter head negative ion device, this effective distance is generally controlled at about 25 cm, or a larger distance, and the limit distance is adjusted to about 20 cm. At this time, it is necessary to cooperate with the vent negative ion device, because there is a strong wind, and the corona field is affected by the wind and the ability of lateral scattering is reduced.

[0040] like Figure 3-7 As shown, the protective film 3 includes a fixing point 33, a groove 34 for placing the shielding metal ring 4, a fitting surface 32 for isolating the air and an air-avoiding hole 31 for housing the negative ion device 2. The air-avoiding hole 1 matches the ventilation hole of the ventilation negative ion device, and its shape and size correspond to the ventilation hole. The purpose is also to fit the installation body 1 to prevent air leakage here; the cross-sectional shape of the groove 34 is set to any one of V-type, trapezoidal or W-type; the overall shape of the protective film 3 is set to any one of circular, polygonal or irregular. The above-mentioned shapes of the protective film 3 can be arbitrarily selected according to customer needs or actual conditions, but one thing to be guaranteed is that the protective film 3 must be tightly arranged on the installation body 1, and an area isolated from air must be formed between the two.

[0041] The material of the protective film 3 is an insulating material, and the material of the protective film 3 is any one of PET, PP, PS, and PVC materials. The protective film 3 is a transparent material, and preferably a transparent PET material. The thickness of the protective film 3 is determined according to the size and practical feasibility, as well as the comprehensive cost factors.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
