Description

Technical Field

[0001] The utility model relates to the technical field of table lamps, in particular to an eye-protecting table lamp with an insect repellent effect. Background Technique

[0002] An eye-protecting table lamp is usually a lighting fixture with a base placed on a desktop. Generally, an eye-protecting table lamp includes a lampshade, a bracket, and a base. The lampshade is fixed to the base through the bracket. A number of lamp beads and a light-transmitting plate are arranged inside the lampshade. The lamp beads emit light, and the light irradiates the desktop below after passing through the light-transmitting plate.

[0003] However, when a traditional eye-protecting table lamp is used in summer, due to the phototaxis of mosquitoes, the light will attract mosquitoes to fly around the table lamp, causing interference to the user and being unfavorable for the user to concentrate on work or study. At the same time, when a traditional eye-protecting table lamp works continuously for a long time in summer, the heat inside the lampshade is difficult to discharge, causing the lamp beads to operate at a higher temperature and easily resulting in the aging of the circuit. Content of the Utility Model

[0004] In view of the deficiencies existing in the existing eye-protecting table lamps in the background technique during use, the utility model provides an eye-protecting table lamp with an insect repellent effect, which has the advantages of driving away mosquitoes and good heat dissipation, and solves the technical problems put forward in the above background technique.

[0005] The utility model provides the following technical solution: An eye-protecting table lamp with an insect repellent effect includes a base. One side of the upper end surface of the base is fixedly connected with a bracket. One side of the upper end of the bracket is fixedly connected with a fixing block. One side of the fixing block is fixedly connected with a cover plate. The lower end of the cover plate is fixedly sleeved with a lampshade. The lower end of the inner side of the lampshade is fixedly connected with a light-transmitting plate. The upper end of the inner side of the lampshade is fixedly connected with a lamp holder. The upper end surface of the lamp holder is fixedly connected with an annular heat conducting plate. One side of the annular heat conducting plate is fixedly connected with a heat conducting block.

[0006] One side of the lower end of the fixing block is fixedly connected with a liquid storage bottle. The upper end of the liquid storage bottle is fixedly sleeved with a liquid guiding rod. The upper end of the liquid guiding rod is fixedly sleeved with a heating tube. An air inlet groove is opened at the midpoint of the front end surface of the fixing block. An air outlet is opened at the midpoint of the rear end surface of the fixing block. A sound-absorbing cotton sleeve is fixedly sleeved inside the air inlet groove. A micro fan is fixedly connected to the rear end of the inner side of the sound-absorbing cotton sleeve.

[0007] Preferably, a guiding rod is fixedly arranged at the upper end of one side inside the fixing block. A heat dissipation plate is slidably connected to the lower end of the guiding rod. The upper end of one side of the heat dissipation plate is fixedly connected with a connecting plate. A tension spring is fixedly connected to the midpoint of the upper end surface of the connecting plate. One end of the tension spring is fixedly connected with the fixing block.

[0008] Preferably, connection blocks are fixedly connected to the front and rear ends of one side of the lower end inside the fixed block. A conductive block is fixedly connected to one side of the lower end face of the heat dissipation plate. The connection blocks are electrically connected to the heating tube. A permanent magnet is fixedly connected to the other side of the lower end face of the heat dissipation plate. An electromagnet is fixedly arranged on one side of the lower end inside the fixed block. A thermistor is fixedly connected to the upper end of the heat conduction block.

[0009] Preferably, the conductive block, the connection blocks and the heating tube can form a series-parallel connection and be connected to the first circuit. The resistance value of the thermistor increases as its own temperature increases. The electromagnet is electrically connected to the thermistor and is connected to the second circuit. The force between the electromagnet and the permanent magnet is an attractive force, and when the attractive force is the largest, it is greater than the pulling force of the tension spring.

[0010] Preferably, a plurality of lamp beads are fixedly arranged on the lower end face of the lamp holder, and the plurality of lamp beads are evenly distributed on the lower end of the lamp holder.

[0011] The utility model has the following beneficial effects:

[0012] 1. Through the cooperation of the liquid storage bottle, the liquid guide rod and the heating tube, the mosquito repellent liquid in the liquid storage bottle is heated and volatilized through the liquid guide rod, and the micro fan is used to generate an air flow to blow out the volatilized mosquito repellent liquid from the air outlet, improving the volatilization efficiency of the mosquito repellent liquid. At the same time, the sound-absorbing cotton sleeve is fixedly sleeved on the outside of the micro fan to prevent the vibration of the micro fan itself from generating additional noise to interfere with the user.

[0013] 2. The heat on the base is dissipated through the annular heat conduction plate and the heat conduction block, and in cooperation with the micro fan, the heat dissipation efficiency is improved to prevent the circuit from aging due to excessive temperature. When the thermistor on the heat conduction block increases to a preset value during long-term use of the eye protection desk lamp in summer, the resistance value decreases to make the attractive force between the electromagnet and the permanent magnet less than the pulling force of the tension spring, causing the heat dissipation plate to move and come into contact with the heat conduction block and the liquid guide rod at the same time, recycling the heat of the lamp holder, promoting heat dissipation by the volatilization of the mosquito repellent liquid, and at the same time disconnecting the first circuit and turning off the heating tube to reduce energy consumption.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , an eye protection table lamp with an insect repellent effect, including a base 1, one side of the upper end surface of the base 1 is fixedly connected with a bracket 2, one side of the upper end of the bracket 2 is fixedly connected with a fixed block 3, one side of the fixed block 3 is fixedly connected with a cover plate 5, the lower end of the cover plate 5 is fixedly sleeved with a lamp shade 4, the lower end of the inner side of the lamp shade 4 is fixedly connected with a light-transmitting plate 10, the upper end of the inner side of the lamp shade 4 is fixedly connected with a lamp holder 6, a plurality of lamp beads are installed on the lower end surface of the lamp holder 6, and the light emitted by the lamp beads forms an eye protection light source through the light-transmitting plate 10. The upper end surface of the lamp holder 6 is fixedly connected with an annular heat conducting plate 7, and one side of the annular heat conducting plate 7 is fixedly connected with a heat conducting block 8. The annular heat conducting plate 7 and the heat conducting block 8 cooperate to conduct the temperature generated when the lamp beads work.

[0022] Refer to Figure 1 , Figure 4 and Figure 5, one side of the lower end of the fixed block 3 is fixedly connected with a liquid storage bottle 24. The liquid storage bottle 24 is filled with mosquito repellent liquid. The upper end of the liquid storage bottle 24 is fixedly sleeved with a liquid guiding rod 20. One end of the liquid guiding rod 20 is located inside the liquid storage bottle 24, and the other end of the liquid guiding rod 20 is located inside the fixed block 3, which is used to export the mosquito repellent liquid in the liquid storage bottle 24 into the fixed block 3. A heating tube 19 is fixedly sleeved near the upper end of the liquid guiding rod 20. The heating tube 19 is used to heat the upper end of the liquid guiding rod 20, which is convenient for the subsequent volatilization of the mosquito repellent liquid. An air inlet groove 23 is opened at the midpoint of the front end face of the fixed block 3, and an air outlet 25 is opened at the midpoint of the rear end face of the fixed block 3. A sound-absorbing cotton sleeve 22 is fixedly sleeved inside the air inlet groove 23. A micro fan 21 is fixedly connected near the rear end inside the sound-absorbing cotton sleeve 22. The sound-absorbing cotton sleeve 22 is used to absorb the sound generated by the working vibration of the micro fan 21. The rotation of the micro fan 21 is used to generate an air flow. The air flow enters the fixed block 3 from the air inlet groove 23, and the air flow takes out the volatilized mosquito repellent liquid gas from the air outlet 25, improving the volatilization efficiency of the mosquito repellent liquid.

[0023] A guide rod 12 is fixedly arranged at the upper end of one side inside the fixed block 3. The lower end of the guide rod 12 is slidably connected with a heat dissipation plate 11. The heat dissipation plate 11 is in an inverted T shape. One side of the upper end of the heat dissipation plate 11 is attached to the heat conduction block 8. The heat conduction block 8 conducts heat to the heat dissipation plate 11. The heat dissipation plate 11 is located at the rear end of the micro fan 21, and the air flow can take away the heat on the surface of the heat dissipation plate 11, improving the heat dissipation efficiency. One side of the upper end of the heat dissipation plate 11 is fixedly connected with a connecting plate 13. A tension spring 14 is fixedly connected at the midpoint of the upper end face of the connecting plate 13. One end of the tension spring 14 is fixedly connected with the fixed block 3, and the contraction of the tension spring 14 drives the connecting plate 13 to move upward.

[0024] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , connection blocks 18 are fixedly connected at the front and rear of one side of the lower end inside the fixed block 3. One side of the lower end face of the heat dissipation plate 11 is fixedly connected with a conductive block 17. The conductive block 17 is located above the connection block 18. The connection block 18 is electrically connected to the heating tube 19. The conductive block 17, the connection block 18 and the heating tube 19 can form a series-parallel connection and be connected to the first circuit. When the conductive block 17 contacts the connection block 18, the heating tube 19 is connected to the first circuit. When the conductive block 17 is separated from the connection block 18, the heating tube 19 is disconnected from the first circuit. A permanent magnet 16 is fixedly connected to the other side of the lower end face of the heat dissipation plate 11. An electromagnet 15 is fixedly arranged at one side of the lower end inside the fixed block 3. The upper end of the heat conduction block 8 is fixedly connected with a thermistor 9. The resistance value of the thermistor 9 increases with the increase of its own temperature. The electromagnet 15 is electrically connected to the thermistor 9 and is connected to the second circuit. The force between the electromagnet 15 and the permanent magnet 16 is an attractive force, and the maximum attractive force is greater than the pulling force of the tension spring 14.

[0025] When the second circuit works, the electromagnet 15 attracts the permanent magnet 16 to move downward, driving the connection block 18 to contact the conductive block 17, the first circuit is connected, and the heating tube 19 heats the liquid guide rod 20. The heat of the lamp holder 6 is conducted to the thermistor 9 through the annular heat conduction plate 7 and the heat conduction block 8. When the temperature of the thermistor 9 reaches the preset value, the resistance value of the second circuit increases, the current flowing through the electromagnet 15 decreases, the magnetism weakens, and the pulling force of the tension spring 14 is greater than the suction force between the electromagnet 15 and the permanent magnet 16. The tension spring 14 drives the heat dissipation plate 11 to move upward through the connecting plate 13. At the same time, the first circuit is disconnected, and the heat dissipation plate 11 moves to contact the heat conduction block 8. At this time, the lower end of one side of the liquid guide rod 20 fits against the upper surface of the heat dissipation plate 11, and the liquid guide rod 20 guides part of the mosquito repellent liquid to the upper surface of the heat dissipation plate 11. The heat dissipation plate 11 can heat the mosquito repellent liquid, and the volatilization of the mosquito repellent liquid can take away the heat of the heat dissipation plate 11, further improving the heat dissipation efficiency and saving the energy consumption of the heating tube 19. When the temperature of the thermistor 9 returns to low temperature, the first circuit is reconnected.

[0026] The usage method (working principle) of the present utility model is as follows:

[0027] Several lamp beads on the lamp holder 6 cooperate with the light-transmitting plate 10 to form an eye-protecting light source. When mosquito repellent is needed, turn on the first circuit to make the heating tube 19 heat the liquid guide rod 20. The liquid guide rod 20 exports the mosquito repellent liquid in the liquid storage bottle 24 and volatilizes it after heating. At the same time, start the micro fan 21 to generate an air flow to take out the volatilized mosquito repellent liquid through the air outlet, improving the volatilization efficiency of the mosquito repellent liquid. The heat of the lamp holder 6 is conducted to the heat dissipation plate 11 through the annular heat conduction plate 7 and the heat conduction block 8, and the heat is taken out by the air flow generated by the micro fan 21. When the heat conducted by the lamp holder 6 makes the temperature of the thermistor 9 reach the preset temperature, the magnetic force of the electromagnet 15 weakens, making the attraction between the electromagnet 15 and the permanent magnet 16 less than the pulling force of the tension spring 14. The tension spring 14 drives the heat dissipation plate 11 to move upward through the connecting plate 13. At the same time, the conductive block 17 is separated from the connection block 18 to disconnect the first circuit, and the heating tube 19 stops working. The liquid guide rod 20 contacts the heat dissipation plate 11, and the mosquito repellent liquid guided by the liquid guide rod 20 absorbs the heat of the heat dissipation plate 11 and volatilizes, recycling the heat generated by the lamp beads of the lamp holder 6 and improving the heat dissipation efficiency.
