Description

Technical Field

[0001] The present invention relates to the technical field of educational supplies, and in particular to a multifunctional educational lighting lamp for school education and a use method thereof. Background Art

[0002] In the education industry, lighting lamps are commonly used lighting accessories that can illuminate educational places such as classrooms at night or in dim weather to facilitate educational activities.

[0003] Since classrooms and other educational places often need to undergo multiple teaching sessions, they need to be used for a long time, so the lighting fixtures in the place often need to be lit for a long time. After being used for a long time, the lamp beads in the lighting lamps will generate a lot of heat due to the thermal effect of the current. At the same time, the indoor ventilation effect is average, so the heat will gradually accumulate and be difficult to dissipate. The lamp beads will be in a high temperature state for a long time, which will greatly reduce the service life of the lighting lamp.

[0010] Preferably, through holes are provided on both sides of the air storage box, and the through holes and the air inlet end of the air guide pipe are respectively arranged on the left and right sides of the sealing plug plate.

[0011] Preferably, the gas storage box is fixedly connected to the side wall of the lamp housing, and electromagnetic control valves are installed at the connection point between the three-way pipe and the air outlet pipe and at the connection point between the three-way pipe and the gas storage box.

[0012] Preferably, an air inlet is provided on the side wall of the air suction cylinder, and the air inlet is communicated with the interior of the lamp housing.

[0013] Preferably, a liquid adding nozzle is fixedly connected to the upper end of the liquid storage tank, and the liquid adding nozzle is communicated with the interior of the liquid storage tank.

[0014] A method for using a multifunctional educational lighting lamp for school education, based on the above-mentioned multifunctional educational lighting lamp for school education, includes the following steps:

[0015] S1. Start the device, so that the LED lamp beads and the small negative pressure fan in the device are powered on and started. After the LED lamp beads are powered on and light up, their light will illuminate through the transparent glass plate on the lower side, and the small negative pressure fan will continue to generate negative pressure airflow after starting, and can inhale cold air from the vents on the side wall of the lamp housing, so as to ventilate and dissipate heat for each LED lamp bead;

[0016] S2. The negative pressure airflow generated by the small negative pressure fan can be discharged to the air outlet pipe and the air storage box through the three-way pipe. When the airflow flows from the inside of the air outlet pipe, it will pass through the liquid inlet pipe inside the liquid storage box. The mosquito repellent in the liquid storage box can enter the liquid inlet pipe through the fine holes, and flow outward with the airflow and finally be discharged from each nozzle;

[0017] S3. Clean the transparent glass plate. The airflow flowing into the air storage box through the three-way pipe will gather between the two sealing plugs. As the air pressure between the two sealing plugs gradually increases and the pressure relief valve in the air guide pipe opens, the air flows into the telescopic airbag along the air guide pipe and forces the telescopic airbag to extend, thereby pushing the guide plate and the U-shaped brush plate to move, and the transparent glass plate on the lower side can be scraped and cleaned;

[0018] S4, reset, the air input into the telescopic airbag will be gradually discharged from the deflation pipe, the air pressure in the telescopic airbag will decrease accordingly, the telescopic airbag will gradually shrink, thereby driving the U-shaped brush plate to move back and reset.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting up a small negative pressure fan, the cold air outside the device can be actively sucked into the lamp housing, so that the cold air can fully contact the internal LED lamp beads, thereby absorbing the heat of the LED lamp beads and then discharging it to the outside, avoiding the LED lamp beads from being in a high temperature state for a long time, and extending the service life of the lighting lamp to a limited extent;

[0021] 2. By setting up the liquid inlet pipe, liquid storage tank and other components, a certain amount of mosquito repellent and clean water can be stored in the two liquid storage tanks respectively. When the airflow flows along the liquid inlet pipe, a pressure difference can be generated at the fine holes on the side wall of the liquid inlet pipe, so that the mosquito repellent and clean water can pass through the fine holes to form a mist and enter the liquid inlet pipe. On the one hand, the atomized liquid can fully absorb the heat in the airflow, thereby improving the heat dissipation and cooling effect. On the other hand, when the atomized mosquito repellent is sprayed from each nozzle, it can be dispersed around the device, effectively driving away mosquitoes attracted by the light, and also preventing the shadow cast by the mosquitoes from affecting the lighting effect;

[0022] 3. By setting the telescopic airbag, the guide plate and the U-shaped brush plate, the two electromagnetic control valves in the three-way pipe can be opened and closed alternately to alternately inject air into the air outlet pipe and the air storage box, so that the air pressure in the air storage box and between the two sealing plugs can gradually increase. When the air pressure rises to a certain value, the air stored in the air storage box is input into the telescopic airbag through the air guide pipe, forcing the telescopic airbag to extend, so as to push the guide plate and the U-shaped brush plate to move, so as to clean the transparent glass plate and maintain the good light transmission effect of the transparent glass plate, thereby ensuring the lighting effect of the device;

[0023] 4. After the telescopic airbag is filled with air, the air can be released from the deflation pipe. On the one hand, the telescopic airbag can be easily retracted after being fully extended, thereby pulling the guide plate and the U-shaped brush plate back to facilitate the next cleaning. On the other hand, the airflow blown out from the deflation pipe can also prevent mosquitoes from approaching and blow away nearby dust to keep the lamp clean. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-8 A multifunctional educational lighting lamp for school education comprises a lamp housing 1, a transparent glass plate 10 is installed at the lower end of the lamp housing 1, and a plurality of LED lamp beads 2 are installed in the lamp housing 1. Figure 3 shown.

[0035] Reference Figure 1 The upper end of the lamp housing 1 is fixedly connected to two liquid storage tanks 7, a side wall of one end of the lamp housing 1 is provided with a plurality of vents 13, and a suction cylinder 3 is fixedly connected to the side wall of the other end of the lamp housing 1, the suction cylinder 3 is connected to the interior of the lamp housing 1, and a small negative pressure fan 21 is installed in the suction cylinder 3. Specifically, in combination with the attached Figure 7 The side wall of the air suction cylinder 3 is provided with an air inlet 22, which is communicated with the interior of the lamp housing 1. When the small negative pressure fan 21 is started, air can be sucked in from the vent 13 on the other side, passed through the interior of the lamp housing 1, and then input into the air suction cylinder 3 along the air inlet 22, and then discharged to the three-way pipe 5.

[0036] The end of the air suction cylinder 3 away from the lamp housing 1 is connected to a three-way pipe 5, the upper end of the three-way pipe 5 is connected to an air outlet pipe 6, and the lower end of the three-way pipe 5 is connected to an air storage box 4. Figure 8 , a liquid inlet pipe 24 is provided in the liquid storage tank 7, and the air outlet pipe 6 is sealed and penetrates the side wall of the liquid storage tank 7 and extends into the liquid storage tank 7, the liquid inlet pipe 24 and the air outlet pipe 6 are connected by a flange and communicate with each other, and a plurality of fine holes 25 are provided on the side wall of the liquid inlet pipe 24, a plurality of heat dissipation fins 9 are fixedly connected to the side wall of the lamp housing 1, a condenser pipe 8 communicating with the inside thereof is fixedly connected to the side wall of the air outlet pipe 6, and a plurality of heat dissipation fins 9 are fixedly connected to the condenser pipe 8, and a plurality of nozzles 12 communicating with the inside thereof are fixedly connected to the side wall of the condenser pipe 8. It should be noted that by setting two liquid storage tanks 7, different liquids, such as mosquito repellent, clean water, air freshener, fragrance, etc., can be put into the two liquid storage tanks 7 to achieve the effects of mosquito repellent, heat dissipation, air purification, and improved breathing experience.

[0037] Specifically, the pores 25 have an extremely small diameter. When the air inside the liquid inlet pipe 24 stops flowing, the pressure difference between the inside and outside of the pores 25 on the side wall of the liquid inlet pipe 24 is small. At this time, under the influence of the surface tension of the liquid, the liquid in the liquid storage tank 7 can form a liquid film at each pore 25, and prevent the liquid in the liquid storage tank 7 from entering the liquid inlet pipe 24. When the air in the liquid inlet pipe 24 starts to flow, since the air flow rate in the liquid inlet pipe 24 is fast and the pressure is relatively small, while the liquid outside the liquid inlet pipe 24 does not flow and the pressure is relatively large, a large pressure difference can be generated inside and outside the pores 25. At this time, the liquid in the liquid storage tank 7 can break the liquid film and allow the liquid in the liquid storage tank 7 to enter the liquid inlet pipe 24. In addition, since the pores 25 have a small diameter, the liquid can form droplets after passing through the pores 25 into the liquid inlet pipe 24, and is diffused into a mist by the air flowing in the liquid inlet pipe 24.

[0038] Reference Figure 5 A guide groove 15 is provided on the side wall of the transparent glass plate 10, a guide plate 16 is slidably connected in the guide groove 15, a U-shaped brush plate 14 is fixedly connected to the lower end of the guide plate 16, a plurality of soft bristles are fixedly connected to the upper end of the U-shaped brush plate 14, and a pushing mechanism for pushing the guide plate 16 to move is installed in the guide groove 15. It should be noted that the soft bristles are in contact with the lower end surface of the transparent glass plate 10, and when the U-shaped brush plate 14 moves, the soft bristles can clean the exposed lower end surface of the transparent glass plate 10.

[0039] The pushing mechanism includes a telescopic airbag 17 fixedly connected to the inner wall of the guide groove 15, and the telescopic airbag 17 is fixedly connected to the guide plate 16. A deflation pipe 26 is fixedly connected to the side wall of the guide plate 16, and the deflation pipe 26 is connected to the inside of the telescopic airbag 17. An injection component for injecting air into the telescopic airbag 17 is installed in the air storage box 4.

[0040] Reference Figure 6 The gas injection assembly includes two sealing plugs 19 that are sealingly and slidably connected in the air storage box 4, and a spring 20 is provided between the two sealing plugs 19, and the two ends of the spring 20 are respectively fixedly connected to the opposite side walls of the two sealing plugs 19. The bottom of the air storage box 4 is fixedly connected with an air guide tube 11 that communicates with the interior thereof, and the end of the air guide tube 11 away from the air storage box 4 communicates with the interior of the telescopic airbag 17, and a pressure relief valve is installed in the air guide tube 11. Through holes 18 are provided on both sides of the air storage box 4, and the through holes 18 and the air inlet end of the air guide tube 11 are respectively provided on the left and right sides of the sealing plug 19. It should be noted that by providing the through holes 18, the left space of the left sealing plug 19 and the right space of the right sealing plug 19 can be connected to the outside, so that the two sealing plugs 19 will not be blocked by air pressure when moving.

[0041] Further, such as Figure 6As shown, the connection between the three-way pipe 5 and the air storage box 4, and the connection between the air storage box 4 and the air duct are both located between the two sealing plug plates 19, so that the air discharged from the three-way pipe 5 into the air storage box 4 can enter between the two sealing plug plates 19, thereby pushing the sealing plug plates 19 to move, and the air is stored between the two sealing plug plates 19. Correspondingly, when the spring 20 pulls the two sealing plug plates 19 to move toward each other, the air will also be discharged from the air duct 11.

[0042] The gas storage box 4 is fixedly connected to the side wall of the lamp housing 1, and electromagnetic control valves are installed at the connection between the three-way pipe 5 and the air outlet pipe 6, and at the connection between the three-way pipe 5 and the gas storage box 4. A liquid filling nozzle 23 is fixedly connected to the upper end of the liquid storage box 7, and the liquid filling nozzle 23 is connected to the inside of the liquid storage box 7.

[0043] The present invention also proposes a method for using a multifunctional educational lighting lamp for school education, which includes the following steps: S1, starting the device, so that the LED lamp beads 2 and the small negative pressure fan 21 in the device are powered on and started, and then after the LED lamp beads 2 are powered on and lighted, their light will pass through the transparent glass plate 10 on the lower side for illumination, and the small negative pressure fan 21 will continue to generate negative pressure airflow after being started, and can inhale cold air from the vents 27 on the side wall of the lamp housing 1, so as to ventilate and dissipate heat for each LED lamp bead 2;

[0044] S2. The lamp repels mosquitoes. The negative pressure airflow generated by the small negative pressure fan 21 can be discharged to the air outlet pipe 6 and the air storage box 4 through the three-way pipe 5. When the airflow flows from the inside of the air outlet pipe 6, it will pass through the liquid inlet pipe 24 inside the liquid storage box 7. The mosquito repellent in the liquid storage box 7 can enter the liquid inlet pipe 24 through the fine hole 25, and finally flow outward with the airflow and be discharged from each nozzle 12;

[0045] S3, cleaning the transparent glass plate 10, the airflow flowing into the air storage box 4 through the three-way pipe 5 will gather between the two sealing plug plates 19, as the air pressure between the two sealing plug plates 19 gradually increases, as the pressure relief valve in the air guide pipe 11 opens, the air flows into the telescopic airbag 17 along the air guide pipe and forces the telescopic airbag 17 to expand, thereby pushing the guide plate 16 and the U-shaped brush plate 14 to move, and the transparent glass plate 10 on the lower side can be scraped and cleaned;

[0046] S4, reset, the air input into the telescopic airbag 17 will be gradually discharged from the deflation pipe 26, the air pressure in the telescopic airbag 17 will decrease accordingly, the telescopic airbag 17 will gradually shrink, thereby driving the U-shaped brush plate 14 to move back and reset.

[0047] Specifically, the use process of this device is as follows: Figure 1 and Figure 2 After the small negative pressure fan 21 in the suction tube 3 is started, negative pressure can be continuously generated, so that the right end of the lamp housing 1 (refer to Figure 2) vent 13 sucks in the cold air from the outside. After the cold air is sucked into the lamp housing 1, it will fully contact with each LED lamp bead 2 inside the lamp housing 1 and absorb the heat of each LED lamp bead 2. The small negative pressure fan 21 discharges the hot air into the right end (refer to Figure 1 ) in the three-way pipe 5. Since the upper and lower ends of the three-way pipe 5 are connected at both ends with electromagnetic control valves, the electromagnetic control valves on the upper and lower sides are alternately opened and closed.

[0048] When the upper electromagnetic control valve is opened, the lower electromagnetic control valve is closed. At this time, the air in the input three-way pipe 5 will be discharged into the upper air outlet pipe 6. When the air containing heat flows along the inside of the air outlet pipe 6, it will enter the liquid inlet pipe 24 in the liquid storage tank 7. Specifically, when the air in the liquid inlet pipe 24 stops flowing, the pressure difference between the inside and outside of the fine holes 25 on the side wall of the liquid inlet pipe 24 is small. At this time, under the influence of the surface tension of the liquid, the liquid in the liquid storage tank 7 can form a layer of liquid film at each fine hole 25, and prevent the liquid in the liquid storage tank 7 from entering the liquid inlet pipe 24. When the air in the liquid inlet pipe 24 starts to flow, because the air in the liquid inlet pipe 24 flows fast and the pressure is relatively small, while the liquid outside the liquid inlet pipe 24 does not flow and the pressure is relatively large, a large pressure difference can be generated inside and outside the fine hole 25. At this time, the liquid in the liquid storage tank 7 can squeeze the liquid film and allow the liquid in the liquid storage tank 7 to enter the liquid inlet pipe 24. Because the aperture of the pores 25 is small, the liquid can form droplets after passing through the pores 25 into the liquid inlet pipe 24, and is diffused into mist by the air flowing in the liquid inlet pipe 24. Finally, the mist liquid can continue to flow with the airflow, flow to the condenser 8 through the outlet pipe 6, and finally be sprayed out from the nozzles 12 on the side walls of the condenser 8. A plurality of heat dissipation fins 9 are connected to the side walls of the condenser 8. The heat generated by the LED lamp beads 2 will also be transferred to the heat dissipation fins 9 through the lamp housing 1. When the mist liquid in the condenser 8 flows with the airflow, it can fully absorb the heat on the heat dissipation fins 9, which can further enhance the heat dissipation and cooling effect of the device.

[0049] Further, such as Figure 1 As shown, mosquito repellent and clean water can be put into the two liquid storage tanks 7 respectively, so that the mosquito repellent and clean water can be mixed into water mist and sprayed out from the nozzle 2, thereby effectively driving away mosquitoes attracted near the lamp, and also preventing the gathered mosquitoes from affecting the lighting effect of the lamp. Alternatively, air fresheners, fragrances, etc. can be put in to improve the air purification level and breathing experience in the classroom.

[0050] In addition, when the electromagnetic control valve on the lower side of the three-way pipe 5 is opened and the electromagnetic control valve on the upper side is closed, the air discharged from the three-way pipe 5 will enter the air storage box 4 and between the two sealing plug plates 19. Since the electromagnetic control valves on the upper and lower sides are opened and closed alternately, the air will be intermittently input into the air storage box 4. As the air input into the air storage box 4 and between the two sealing plug plates 19 continues to increase, the air pressure between the two sealing plug plates 19 continues to rise, and the two sealing plug plates 19 are forced to move away from each other, and the spring 20 is stretched at the same time. When the air pressure between the two sealing plug plates 19 rises to the threshold value of the pressure relief valve in the air guide pipe 11, the pressure relief valve in the air guide pipe 11 is opened, and the spring 20 contracts rapidly and pulls the two sealing plug plates 19 to move toward each other. At this time, the air between the two sealing plug plates 19 can be quickly input into the telescopic airbag 17 through the air guide pipe 11. Figure 5 , part of the air can be discharged from the vent pipe 26, and because the diameter of the vent pipe 26 is very small, the amount of air entering the telescopic airbag 17 is much greater than the amount of air discharged from the vent pipe 26, and the air pressure in the telescopic airbag 17 continues to rise, which can force the telescopic airbag 17 to expand. The expanded telescopic airbag 17 can push the guide plate 16 to move along the guide groove 15, and finally drive the U-shaped brush plate 14 to move synchronously. When the U-shaped brush plate 14 moves, the bristles on its surface can clean the outer surface of the transparent glass plate 10 below to maintain the good light transmittance of the transparent glass plate 10, so that the device has a good lighting effect. In addition, it is worth mentioning that it is not difficult to see from the above that the U-shaped brush plate 14 will only move once and clean it when the pressure relief valve in the air guide pipe 11 is opened. Therefore, the transparent glass plate 10 can be automatically cleaned once at regular intervals in the device, which will not excessively affect the lighting use of the lamp, and can be automatically cleaned without manual intervention.

[0051] When the spring 20 pulls the two sealing plug plates 19 back and reset, the two sealing plug plates 19 also stop moving, and correspondingly, the air supply to the telescopic airbag 17 through the air guide tube 11 also stops. The telescopic airbag 17 gradually shrinks under its own elastic force and releases the air inside it through the air release tube 26. After the telescopic airbag 17 shrinks, it will also pull the guide plate 16 and the U-shaped brush plate 14 back and reset, which is convenient for cleaning next time.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

8. The multifunctional educational lighting lamp for school education according to claim 1, characterized in that: A liquid adding nozzle (23) is fixedly connected to the upper end of the liquid storage tank (7), and the liquid adding nozzle (23) is in communication with the interior of the liquid storage tank (7).

9. A method for using a multifunctional educational lighting lamp for school education, based on the multifunctional educational lighting lamp for school education according to any one of claims 1 to 8, characterized in that: The usage steps include: S1, starting the device, so that the LED lamp beads (2) and the small negative pressure fan (21) in the device are powered on and started, and then the LED lamp beads (2) are powered on and lighted, and their light will pass through the transparent glass plate (10) on the lower side to illuminate, and the small negative pressure fan (21) will continue to generate negative pressure airflow after being started, and can suck cold air from the vents (27) on the side wall of the lamp housing (1), so as to ventilate and dissipate heat for each LED lamp bead (2); S2. The lamp repels mosquitoes. The negative pressure airflow generated by the small negative pressure fan (21) can be discharged to the air outlet pipe (6) and the air storage box (4) through the three-way pipe (5). When the airflow flows from the inside of the air outlet pipe (6), it will pass through the liquid inlet pipe (24) inside the liquid storage box (7). The mosquito repellent in the liquid storage box (7) can enter the liquid inlet pipe (24) through the fine hole (25) and flow outward with the airflow to be discharged from each nozzle (12); S3, cleaning the transparent glass plate (10), the airflow flowing into the air storage box (4) through the three-way pipe (5) will gather between the two sealing plug plates (19), as the air pressure between the two sealing plug plates (19) gradually increases, as the pressure relief valve in the air guide pipe (11) opens, the air flows into the telescopic airbag (17) along the air guide pipe and forces the telescopic airbag (17) to expand, thereby pushing the guide plate (16) and the U-shaped brush plate (14) to move, and the transparent glass plate (10) on the lower side can be scraped and cleaned; S4, reset, the air input into the telescopic airbag (17) will be gradually discharged from the deflation pipe (26), the air pressure in the telescopic airbag (17) will be reduced accordingly, the telescopic airbag (17) will gradually shrink, thereby driving the U-shaped brush plate (14) to move back and reset.
