Description

Technical Field

[0001] This utility model belongs to the field of floor lamp technology, specifically relating to an eye-protecting lamp with negative ions. Background Technology

[0002] A floor lamp with negative ion air purification function disclosed in the technical solution of reference application number CN202422371440.X includes: a support rod, a lamp head detachably fixed to the top of the support rod, and a base detachably fixed to the bottom of the support rod; the lamp head includes: a lamp head frame, two first LED light sources, a buffer sheet, reflective paper, a light guide plate, a diffusion film, an acrylic plate, an acrylic plate, and a mounting back plate. The lamp head frame extends inward to form an abutment boss. After the mounting back plate is installed on the back of the lamp head frame, the buffer sheet, reflective paper, light guide plate, diffusion film, acrylic plate, and acrylic plate are sequentially pressed against the abutment boss from top to bottom. The two first LED light sources are installed on both sides of the lamp head frame facing the side of the light guide plate to emit light. The lamp head also includes: a negative ion generator, which is installed on the back of the mounting back plate. The back of the mounting back plate is provided with a first wire hole, and the power cord from the lamp head is connected to the negative ion generator through the first wire hole.

[0003] However, the structure of the negative ion generator in this technology is independent of the overall floor lamp, which disrupts the consistency and continuity of the overall design. The independent structure means that the negative ion generator cannot rely on the lamp head shell to form protection, and its protection level is disconnected from the main body of the floor lamp. It is susceptible to dust, water stains, and external impact corrosion. In addition, it needs to be connected to the lamp body through an additional auxiliary fixing device, which not only poses a safety hazard of loose fixing and falling off, but may also damage the original structural integrity of the lamp body. Furthermore, the external generator will occupy additional external space of the lamp body, which can easily interfere with surrounding furniture and reduce the spatial adaptability of the floor lamp. Utility Model Content

[0004] In order to overcome at least some of the shortcomings of the prior art, this utility model provides an eye-protecting lamp with negative ions.

[0005] The technical solution provided by this utility model is as follows: A floor lamp with negative ions includes a floor lamp body and a negative ion generating component. The floor lamp body includes a lamp base, a lamp post, and a lamp head. One end of the lamp post is installed on the lamp base, and the lamp head is installed on the other end of the lamp post. The lamp head has a lamp groove and a negative ion groove. The negative ion groove extends outward from the lamp groove. An air outlet is provided in the center of the negative ion groove. A fan mounting wall is provided around the air outlet. The fan mounting wall is installed on the inner side of the negative ion groove. The negative ion generating component includes a power supply board, a high-voltage generator, a fan, needles, and an air inlet cover. The power supply board is fixed to the inner side of the negative ion groove by a snap-fit ​​structure. The fan is installed on the inner side of the fan mounting wall. A plurality of high-voltage generators are evenly and symmetrically distributed on the outer side of the fan. The fan mounting wall is equipped with the same number of needles as the high-voltage generators. The air inlet cover is installed on the negative ion groove. The power supply board is connected to the high-voltage generator through a circuit, and the high-voltage generator is connected to the needles through a circuit.

[0006] Furthermore, the needle includes a positive electrode needle, a negative electrode needle, and a mounting plate. The positive electrode needle and the negative electrode needle are symmetrically distributed on the horizontal arm of the mounting plate, and their needle tips face the same direction. The needle tip areas of the positive electrode needle and the negative electrode needle form a negative ion generating area, and the fan is located below the negative ion generating area.

[0007] Furthermore, the mounting plate is provided with a cross arm and a web plate, and the mounting plate is generally T-shaped. The web plate is provided with mounting holes for connecting to the fan mounting wall.

[0008] Furthermore, the air inlet top cover is provided with an air guide groove and an air inlet, with the air inlets densely arranged at the end area of ​​the air guide groove.

[0009] Furthermore, the air inlets are distributed in an array pattern.

[0010] Furthermore, the air guide trough has an inclined structure.

[0011] Furthermore, the air outlet is a circularly distributed honeycomb array of air outlets.

[0012] Furthermore, an anti-slip pad is connected to the bottom of the lamp holder, and the anti-slip pad is completely in contact with the bottom surface of the lamp holder.

[0013] Furthermore, it also includes a threaded sleeve, which is connected between the lamp post and the lamp holder, with its two ends respectively engaging with the bottom end of the lamp post and the top end of the lamp holder.

[0014] Furthermore, the lamp head also includes an upper cover, an upper lampshade, a lower lampshade, a main lamp, and an ambient lamp. The ambient lamp is installed upward in the lamp groove, the upper lampshade covers the outside of the ambient lamp, the main lamp is installed downward in the lamp groove, the lower lampshade covers the outside of the main lamp, and the upper cover is installed in the lamp groove.

[0015] The beneficial effects of this utility model are as follows: A negative ion groove extends forward from the lamp head as the installation position for the negative ion generating component, completely hiding and integrating the negative ion generating component inside the lamp head. This gives the floor lamp a simple appearance without any obtrusive structure, perfectly matching the aesthetic needs of home furnishings. At the same time, the negative ion generating component is protected by the lamp head shell, ensuring that its protection level is consistent with that of the main body of the floor lamp, effectively preventing external environmental corrosion of the component. Furthermore, this hidden structure does not require additional auxiliary fixing devices. The component can be accurately positioned and securely installed through the pre-set installation position in the empty groove, without occupying external space of the lamp head and avoiding potential interference with surrounding furniture.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0024] See Figures 1 to 6 This embodiment discloses an eye-protecting lamp with negative ions, including a floor lamp body 1 and a negative ion generating component 2. The negative ion generating component 2 is installed inside the floor lamp body 1. The floor lamp body 1 is composed of a lamp base 11, a lamp post 12, and a lamp head 13. One end of the lamp post 12 is installed on the lamp base 11, and the other end is installed on the lamp head 13. The lamp head 13 has a lamp groove 131 and a negative ion groove 132, and the lamp groove 131 extends outward to form the negative ion groove 132. The negative ion generating component 2 includes a power supply board 21, a high-voltage generator 22, a fan 23, a needle 24, and an air inlet top cover 25. The negative ion groove 132 has a circular honeycomb-shaped air outlet 1321 in the center, which is composed of multiple small honeycomb-shaped holes evenly arranged. The overall structure is a circular air outlet with uniform and densely distributed holes, which can ensure the smooth flow of air rich in negative ions and can also make the airflow uniformly diffused through the honeycomb structure. The air is blown outwards. The air outlet 1321 is surrounded by a fan mounting wall 1322 adapted to the size of the fan 23. The fan 23 is tightly installed inside the air outlet 1321, and the mounting plane is flush with the end face of the air outlet 1321. This structure ensures that when the fan 23 rotates, it efficiently draws the ionized air in the negative ion tank 132 and quickly exits it through the air outlet 1321. At the same time, the inner wall of the fan mounting wall 1322 fits tightly with the outer contour of the fan 23 without obvious gaps, which can effectively prevent airflow from leaking from gaps and ensure that the wind force of the fan 23 is all applied to the negative ion air to improve the air delivery efficiency. With the help of the combined structure of the air outlet 1321 and the fan mounting wall 1322, the ionized negative ion-rich air can flow out of the lamp head 13 and blow towards the irradiation area of ​​the main lamp 137, so that the negative ions are concentrated to cover the user's usage range and ensure that the user is in contact with the negative ion air to the maximum extent during the lighting process.

[0025] The power supply board 21 is fixed to the inner side of the negative ion tank 132 by a snap-fit ​​structure. The installation position avoids the airflow channel. The snap-fit ​​structure can ensure that the power supply board 21 is firmly attached to the tank wall, the force is even, and it will not loosen after long-term use. At the same time, this installation position does not affect the airflow path in the negative ion tank 132 and can also avoid the airflow directly impacting the power supply board 21, which would cause dust accumulation. Several high-voltage generators 22 are evenly and symmetrically distributed on the outer side of the fan 23. The fan mounting wall 1322 is equipped with needles 24 in the same number as the high-voltage generators 22, and the needles 24 are connected to the high-voltage generators 22 one by one. The installation position of the needles 24 is aligned with the core area of ​​the airflow channel to ensure that the external air entering the negative ion tank 132 can flow directly through the high-voltage electric field area around the needles 24 and be fully ionized to improve the negative ion generation efficiency.

[0026] In this embodiment, the needle 24 consists of a positive electrode needle 241, a negative electrode needle 242, and a mounting plate 243. The mounting plate 243 has a horizontal arm 2431 and a web 2432, forming an overall T-shape. The positive electrode needle 241 and the negative electrode needle 242 are symmetrically distributed on the horizontal arm 2431 of the mounting plate 243, and their tips face the same direction to ensure the symmetry and uniformity of the ionization region. This type of needle is made of stainless steel and relies on high-voltage corona discharge technology to achieve ionization. This technology uses a high-voltage electric field to ionize the air around the needle tip to generate negative ions, which has the advantages of low cost, simple structure, and small size. The web 2432 has mounting holes for fixing the needle 24 to the fan mounting wall 1322. This mounting position ensures that unionized external air can flow fully through the needle 24 for ionization after reaching the negative ion tank 132 along a preset path.

[0027] It is worth noting that the positive electrode needle 241 and the negative electrode needle 242 must maintain a preset reasonable distance. This distance directly affects the ionization effect and the safety of the device. If the two are in contact or the distance is too close, it will cause a short circuit in the output circuit of the high voltage generator 22, which will not only damage the high voltage generator 22 but may also cause internal circuit failures in the device. Maintaining a preset reasonable distance can enable the needle tip area to form a stable high voltage electric field, meet the technical conditions of high voltage corona discharge, and achieve efficient and stable air ionization. If the distance exceeds the preset range, the electric field strength in the needle tip area will be insufficient, and the electric field threshold required for air ionization will not be reached, resulting in a significant decrease in the negative ion generation efficiency and affecting the core function of the device. In addition, the horizontal arm 2431 is located in the high voltage electric field outlet area. This structure can ensure that the positive electrode needle 241 and the negative electrode needle 242 are completely in the high voltage electric field environment, ensuring that the needle tip continuously and stably ionizes the air flowing out of the high voltage electric field area to ensure the negative ion output performance.

[0028] In this embodiment, the air inlet cover 25 is provided with an air guide groove 251 and an air inlet 252. The air guide groove 251 adopts a sloping structure, and its sloping angle is adapted to the internal space of the negative ion tank 132, which can form a smooth and unobstructed airflow channel. It guides the external air smoothly and directionally to the air inlet 252 along a preset flow direction, effectively avoiding the generation of vortices or turbulence during airflow guidance, and ensuring smooth airflow and controllable direction. The air inlets 252 are arranged in an array, densely distributed at the end area of ​​the air guide groove 251, and fully correspond to the air intake area of ​​the fan 23. This structure can maximize the introduction of external air for the negative ion generator. The generating component 2 provides ample air supply to meet the continuous ionization requirements. It also divides the airflow into multiple uniform and fine airflows through a uniformly distributed perforated structure. This ensures that the airflow is evenly dispersed after entering the negative ion tank 132, avoiding excessively high local wind speeds that would result in insufficient contact time between the air and the needle tip 24 and incomplete ionization, or excessively low local wind speeds that would cause negative ion accumulation and poor output. Ultimately, it ensures that the air entering the negative ion tank 132 can flow smoothly and evenly through the area between the high-voltage generator 22 and the needle tip 24, fully contacting and ionizing with the needle tip. This significantly improves the uniformity and stability of negative ion generation, ensuring a balanced concentration of negative ions within the area illuminated by the eye-protection lamp.

[0029] In this embodiment, the lamp holder 11 is integrally cast from cast iron, with an anti-slip pad 14 attached to the bottom to improve placement stability. The lamp post 12 is made of aluminum alloy profile and anodized to form a wear-resistant and corrosion-resistant layer on the surface, extending its service life. The lamp post 12 is vertically installed on the lamp holder 11 by several sets of internal hexagonal bolts. The bolts are completely embedded in the pre-set threaded sleeves 15 inside the lamp post 12, achieving fully concealed bolt installation and effectively avoiding exposed fasteners from compromising the minimalist appearance of the product.

[0030] In this embodiment, the lamp head 13 includes an upper cover 133, an upper lampshade 134, a lower lampshade 135, a main lamp 136, and an ambient lamp 137. The ambient lamp 137 is installed upward within the lamp groove 131, and the upper lampshade 134 covers the outside of the ambient lamp 137. The main lamp 136 is installed downward within the lamp groove 131, and the lower lampshade 135 covers the outside of the main lamp 136. The upper cover 133 is bolted into the lamp groove 131. Furthermore, both the upper lampshade 134 and the lower lampshade 135 employ a frosted finish, which softens the light, prevents glare, and protects the main lamp 136 and the ambient lamp 137. The connection between the upper cover 133 and the lamp groove 131 is a concealed structure, with the bolts fully embedded in the pre-drilled mounting holes in the lamp groove 131. This ensures a stable connection while preventing the bolts from protruding and compromising the clean appearance of the lamp head 13.

[0031] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
