[0002] In recent years, with the widespread use of outdoor lighting equipment, the problem of surface pollution of lamps caused by mosquitoes gathering towards light has become increasingly prominent. Excessive mosquito pollution will affect the brightness of lighting fixtures.

[0003] Traditional mosquito repellent lamps mostly use physical barriers (such as gauze) or chemical mosquito repellents. Although screens, insect nets and other devices can block mosquitoes, after long-term use, these devices are prone to dust accumulation and residual mosquito corpses, which in turn affects the light transmittance of the lighting fixtures. The use of chemical mosquito repellents requires manual regular replenishment of the agent, which has high maintenance costs. In addition, chemical residues may harm the environment and human health.

[0004] Therefore, there is an urgent need for an integrated lighting fixture that integrates mosquito prevention, self-cleaning and lighting functions. Summary of the Invention

[0033] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please refer to Figures 1 to 12 , a lighting fixture for preventing mosquito interference provided by the present invention includes a lamp body, a connecting pipe 52, and a driving mechanism. Specifically, the connecting pipe 52 is rotatably arranged on the lamp body, and the connecting pipe 52 is provided with a flow channel 10 with an open end along its axial extension direction. The tube wall of the connecting pipe 52 is provided with a spray hole 521 on the side facing the lamp body. The spray hole 521 is connected to the flow channel 10. The open end of the flow channel 10 is used to input gas with a certain flow rate. The gas flows to the spray hole 521 through the flow channel 10 and is ejected from the spray hole 521. The driving mechanism is connected to the connecting pipe 52 in a transmission manner. When the driving mechanism is in a working state, the driving mechanism drives the connecting pipe 52 to rotate around the lamp body. When the connecting pipe 52 rotates, the spray hole 521 always faces the lamp body, so that the gas ejected from the spray hole 521 can blow the entire outer surface of the lamp body, thereby blowing away impurities such as insect corpses, dust particles, etc. on the outer surface of the lamp body.

[0037] It should be noted that the number of nozzles 521 can be one, two, or three, etc. The specific number of nozzles 521 needs to be set to ensure that the gas ejected from the nozzles 521 can cover the entire outer surface of the lamp body. In addition, to ensure that the gas ejected from the connecting tube 52 can completely cover the entire outer surface of the lamp body when the connecting tube 52 rotates, it is also necessary to design the connecting tube 52 to match the shape of the lamp body. For example, the lamp body is spherical or nearly spherical as a whole, and the connecting tube 52 is designed to be semicircular. The connecting tube 52 is then rotated around the central axis of the lamp body. In this way, the gas ejected from the nozzles 521 can completely cover the entire outer surface of the lamp body with each rotation of the connecting tube 52.

[0038] In some optional embodiments, such as Figure 1 、 Figure 2 As shown, the lamp body includes a lamp holder 3 and a lampshade 4. The lampshade 4 covers the lamp holder 3. One end of the lamp holder 3 is fixed to the base 1 through a fixing rod 2. The closed end of the connecting pipe 52 is rotatably set on the fixing rod 2 through a sleeve 51.

[0039] In some optional embodiments, such as Figure 3 、 Figure 4As shown, the drive mechanism includes a rotary motor 53 and a transmission box 5. The housing of the rotary motor 53 is fixed to the base 1, and the rotating shaft 64 of the rotary motor 53 is driven to connect the sleeve 51 through the transmission box 5. Optionally, the transmission box 5 is a cascaded multi-stage gear set, which converts the low output torque of the rotary motor 53 at a high speed into a high output torque at a low speed for the sleeve 51, thereby ensuring that the connecting pipe 52 operates in a suitable state.

[0040] In some environments, impurities stuck on the outer surface of the lamp body cannot be blown away by the gas ejected from the nozzle 521. For example, powdery substances on insects stick to the outer surface of the lamp body and form stubborn stains after being exposed to wind and sun for a long time. These stains not only affect the appearance of the lamp, but also affect the lighting brightness of the lamp. To this end, in some optional embodiments, the lighting fixture for preventing mosquito interference also includes a water supply component, which is used to input a cleaning liquid, such as clean water, into the flow channel 10. The cleaning liquid is ejected from the nozzle 521 through the flow channel 10. Specifically, Figure 6 As shown, the water delivery assembly includes an air inlet pipe 55, an on-off valve, and an opening and closing device. Specifically, the open end of the connecting pipe 52 is pivotally mounted on the air inlet pipe 55 via a connecting pipe 56, and the open end of the connecting pipe 52 is connected to the air inlet pipe 55, thereby connecting the flow channel 10 to the air inlet pipe 55. The on-off valve is mounted on the air inlet pipe 55, and the inlet end of the on-off valve is connected to the water supply pipe 61, which is used to connect to external water delivery equipment. The opening and closing device is used to open and close the on-off valve. When the opening and closing device opens the on-off valve, the on-off valve is connected to the flow channel 10, and the external cleaning liquid passes through the on-off valve, the air inlet pipe 55, the connecting pipe 52, and finally is ejected from the spray hole 521. When the opening and closing device closes the on-off valve, the on-off valve is disconnected from the flow channel 10.

[0041] In some optional embodiments, such as Figure 2 As shown, the air intake pipe 55 is fixed on the base 1. The base 1 supports the air intake pipe 55, so that the air intake pipe 55 supports the left end of the connecting pipe 52. Since the base 1 also supports the right end of the connecting pipe 52, the connecting pipe 52 rotates more smoothly.

[0042] In some optional embodiments, in order to ensure that the connecting pipe 52 has high stability when rotating, as shown in FIG. Figure 3 As shown, the air inlet pipe 55 is also rotatably arranged on the lamp holder 3.

[0043] In some optional embodiments, such as Figure 6 As shown, a one-way valve 62 is also connected in series between the switch valve and the air inlet pipe 55. By providing the one-way valve 62, the backflow of the cleaning liquid input into the air inlet pipe 55 can be avoided, and the gas input into the air inlet pipe 55 can be avoided from entering the switch valve and affecting the opening and closing of the switch valve.

[0044] It can be understood that in this embodiment, gas and cleaning liquid can be delivered to the air intake pipe 55 at the same time, or gas can be delivered to the air intake pipe 55 first and then cleaning liquid is delivered to the air intake pipe 55, or cleaning liquid can be delivered to the air intake pipe 55 first and then gas is delivered to the air intake pipe 55.

[0045] In some optional embodiments, such as Figure 5 、 Figure 6 As shown, the opening and closing device includes a first gear 65, a rack 68, and a driver 67. Specifically, the first gear 65 is rotatably mounted on the housing of the switch valve and is connected to the valve body 63 in the housing of the switch valve via a rotating shaft 64. The rack 68 is engaged with the first gear 65, and the driver 67 is used to drive the rack 68 to move horizontally.

[0046] In this embodiment, for example, Figure 5 As shown, when the driver 67 drives the rack 68 to move horizontally to the left, the first gear 65 drives the valve body 63 of the switch valve to rotate clockwise, and the switch valve is in the open state; when the driver 67 drives the rack 68 to move horizontally to the right, the first gear 65 drives the valve body 63 of the switch valve to rotate counterclockwise, and the switch valve is in the closed state.

[0047] In some optional embodiments, the driver 67 includes a telescopic motor, the housing of which is fixed to the base 1, and the telescopic rod of the telescopic motor is connected to the rack 68. When the telescopic rod of the telescopic motor moves linearly, it drives the rack 68 to move linearly, causing the first gear 65 engaged with the rack 68 to rotate. The first gear 65 then drives the valve body 63 to rotate via the rotating shaft 64, thereby achieving the purpose of opening and closing the valve.

[0048] In some optional embodiments, in order to protect the first gear 65, the rack 68, and the driver 67, as shown in FIG. Figure 5 As shown, a first protective shell 6 is provided on the base 1 .

[0049] In some environments, impurities stuck on the outer surface of the lamp body cannot be swept away by the gas and water jetted from the nozzle 521. For example, highly viscous substances may stick to the outer surface of the lamp body. Therefore, in some optional embodiments, the lighting fixture for preventing mosquito interference further includes a sweeping brush assembly, which contacts the outer surface of the rotating lamp body through the sweeping brush assembly to forcibly remove these substances. Specifically, Figures 7 to 9As shown, the sweeping brush assembly includes a slider 73, a cleaning brush 77, a toggle mechanism, and a first reset mechanism. The slider 73 is slidably mounted on the connecting tube 52, and the cleaning brush 77 is slidably mounted on the connecting tube 52. For example, the lamp body is spherical or nearly spherical, and the connecting tube 52 is semicircular. The slider 73 is provided with an inclined plate 74. The cleaning brush 77 is slidably mounted on one end surface of the connecting tube 52 along the radial direction of the connecting tube 52. The bottom of the cleaning brush 77 forms an oblique wedge fit with the inclined plate 74. When the slider 73 moves along the circumferential extension of the connecting tube 52, the upper inclined surface of the inclined plate 74 pushes against the bottom of the cleaning brush 77, causing the cleaning brush 77 to move up and down along the radial direction of the connecting tube 52. Preferably, to ensure a more stable oblique wedge fit between the bottom of the cleaning brush 77 and the inclined plate 74, a limiting groove is provided on the upper inclined surface of the inclined plate 74. The bottom of the cleaning brush 77 is limited in its movement within the limiting groove. The toggle mechanism is used to periodically drive the slider 73 to move along the circumferential extension path of the connecting tube 52, so that the slider 73 drives the cleaning brush 77 to approach and move away from the lamp body. The first reset mechanism is arranged between the connecting tube 52 and the slider 73. When the cleaning brush 77 approaches the lamp body and the toggle mechanism does not work, the first reset mechanism drives the slider 73 to move on the connecting tube 52, so that the slider 73 drives the cleaning brush 77 away from the lamp body. In this way, the cleaning brush 77 periodically contacts and moves away from the outer surface of the lamp body, so that the stains on the outer surface of the lamp body are cleaned.

[0050] In some optional embodiments, such as Figure 9 、 Figure 10 As shown, the first return mechanism includes a first slide rail 75 and a first spring 76. Both ends of the first slide rail 75 are fixed to the connecting pipe 52. One end of the slider 73 slides over the first slide rail 75 via a baffle. The first spring 76 is sleeved on the first slide rail 75 and is located between the end of the first slide rail 75 away from the baffle and the baffle. When the slider 73 moves along the path extending from the circumference of the connecting pipe 52, the first spring 76 compresses and expands.

[0051] In some optional embodiments, in order to protect the slider 73, as Figure 1 As shown, a second protective shell 9 is provided on the connecting pipe 52 .

[0052] In some optional embodiments, such as Figure 7 、 Figure 8 、 Figure 10As shown, the toggle mechanism includes a push rod 66, a cam plate 7, a toggle lever 11, and a second return mechanism 72. Specifically, one end of the push rod 66 is connected to the first gear 65, and the other end is located on one side of the cam plate 7. When the first gear 65 rotates, the other end of the push rod 66 rotates accordingly, moving away from and toward the cam plate 7. The cam plate 7 is mounted on the intake pipe 55 so that it slides axially along the intake pipe 55. The cam plate 7 is radially constrained to the intake pipe 55, so that the cam plate 7 can only slide left and right along the axial direction of the intake pipe 55. The toggle lever 11 is connected to a slider 73 and is located on the other side of the cam plate 7 from the push rod 66. The second return mechanism 72 is located between the connecting pipe 52 and the cam plate 7 to provide an elastic restoring force that prevents the cam plate 7 from approaching the toggle lever 11. When the first gear 65 rotates to open the switch valve, the push rod 66 pushes the cam plate 7 toward the side of the lever 11 away from one end of the first gear 65, so that the cam plate 7 moves to the right along the axial direction of the intake pipe 55 until the raised portion of the cam plate 7 overlaps with the rotation path of the lever 11. When the rotating lever 11 touches the raised portion of the cam plate 7, the cam plate 7 squeezes the lever 11, so that the slider 73 moves along the circumferential extension path of the connecting pipe 52, so that the slider 73 drives the cleaning brush 77 to approach the lamp body. At this time, the second reset mechanism 72 provides an elastic restoring force to prevent the cam plate 7 from approaching the lever 11. When the rotating lever 11 moves away from the raised portion of the cam plate 7, the elastic restoring force provided by the second reset mechanism 72 drives the cam plate 7 to move leftward along the axial direction of the intake pipe 55 until the raised portion of the cam plate 7 does not overlap with the rotation path of the lever 11. The elastic restoring force provided by the first reset mechanism drives the slider 73 to move in the opposite direction along the circumferential extension path of the connecting pipe 52, so that the slider 73 drives the cleaning brush 77 away from the lamp body.

[0053] In some optional embodiments, the second reset mechanism 72 is a spring sleeved on the intake pipe 55 . When the cam plate 7 approaches the shift lever 11 , the spring is stretched, thereby generating an elastic restoring force that prevents the cam plate 7 from approaching the shift lever 11 .

[0054] In some optional embodiments, when the end of the push rod 66 away from the first gear 65 pushes the cam plate 7, the push rod 66 can move smoothly relative to the left end surface of the cam plate 7, such as Figure 6 As shown, a roller 71 is provided at one end of the push rod 66 away from the first gear 65. The roller 71 is in rolling contact with the left end face of the cam plate 7 to reduce friction between the two during relative movement, making it easier for the first gear 65 to drive the push rod 66 to rotate.

[0055] In some optional embodiments, when the cleaning brush 77 periodically contacts and moves away from the outer surface of the lamp body, in order to facilitate the cleaning brush 77 to clean the protruding stains on the outer surface of the lamp body, such as Figure 10As shown, a shock absorber 79 is provided between the cleaning brush 77 and the connecting pipe 52. Through the buffering effect of the shock absorber 79, when the cleaning brush 77 touches the protruding stains, the cleaning brush 77 can be prevented from strongly colliding with the stains, thereby protecting the cleaning brush 77 from being damaged by the impact of sticky and stubborn stains.

[0056] In some optional embodiments, the lighting fixture for preventing mosquito interference further includes a flow regulating component for periodically adjusting the size of the spray hole 521 to improve the purging effect. Figure 11 、 Figure 12 As shown, the flow regulating assembly includes a cover plate 8 and a reciprocating drive assembly. Specifically, the cover plate 8 is slidably mounted on the connecting tube 52. The cover plate 8 is provided with an opening 81 aligned with the nozzle 521. The reciprocating drive assembly is used to drive the cover plate 8 to reciprocate along the circumferential extension of the connecting tube 52 as the connecting tube 52 rotates, causing the opening 81 and the nozzle 521 to periodically shift and align. When the opening 81 and the nozzle 521 are misaligned, the effective area of ​​the nozzle 521 is reduced, and the pressure of the airflow and / or water flow ejected from the nozzle 521 increases. When the opening 81 and the nozzle 521 are aligned, the effective area of ​​the nozzle 521 is increased, and the pressure of the airflow and / or water flow ejected from the nozzle 521 is reduced. In this way, by controlling the pressure of the airflow and / or water flow ejected from the nozzle 521, the impact force of the airflow and / or water flow on the outer surface of the lamp body is adjusted, so that stains are dispersed by the periodically changing impact force, thereby quickly removing stubborn stains.

[0057] In some optional embodiments, such as Figure 11 、 Figure 12 As shown, the reciprocating drive assembly includes a corrugated block 85, a connecting rod 82, and a third reset mechanism. Specifically, the corrugated block 85 is provided on the connecting tube 52, and when the connecting tube 52 rotates, the corrugated block 85 rotates around a certain rotation axis. Preferably, the corrugated block 85 is rotatably provided on the fixed rod 2, and the corrugated block 85 is connected to the connecting tube 52, so that the corrugated block 85 rotates around the center axis of the fixed rod 2. The circumferential edge of the corrugated block 85 is provided with arc-shaped protrusions 851 at intervals, the lower end of the connecting rod 82 is connected to the cover plate 8, and the upper end of the connecting rod 82 abuts against the circumferential edge of the corrugated block 85. The third reset mechanism is provided between the connecting tube 52 and the cover plate 8, and is used to provide an elastic restoring force that drives the position of the opening 81 to be aligned with the nozzle 521.

[0058] In this embodiment, when the waveform block 85 rotates, when the arc-shaped protrusion 851 pushes the connecting rod 82 downward, the connecting rod 82 pushes the cover plate 8 to move on the connecting pipe 52, so that the opening 81 and the spray hole 521 are misaligned. When the recessed area between adjacent arc-shaped protrusions 851 corresponds to the upper end position of the connecting rod 82, under the action of the elastic restoring force provided by the third reset mechanism, the cover plate 8 is pushed to move on the connecting pipe 52, so that the opening 81 and the spray hole 521 are aligned. During this process, the upper end of the connecting rod 82 moves upward until it rests on the recessed area between adjacent arc-shaped protrusions 851. In this way, by periodically adjusting the relative position between the opening 81 and the spray hole 521, the pressure of the airflow and / or water flow ejected from the spray hole 521 can be controlled, and then the impact force of the airflow and / or water flow impacting the outer surface of the lamp body can be adjusted, so that the stains are dispersed by the periodically changing impact force, thereby quickly removing stubborn stains.

[0059] In some optional embodiments, such as Figure 11 、 Figure 12 As shown, the third return mechanism includes a second slide rail 83 and a second spring 84. Both ends of the second slide rail 83 are fixed to the connecting pipe 52. One end of the cover plate 8 slides over the second slide rail 83 via a stopper. The second spring 84 is mounted on the second slide rail 83 and is located between the end of the second slide rail 83 away from the stopper and the stopper. When the cover plate 8 moves along the path extending from the circumference of the connecting pipe 52, the second spring 84 compresses and expands.

[0060] In some optional embodiments, a second gear (not shown in the drawings) is provided at the end of the connecting tube 52, and the driving mechanism is connected to the second gear through a multi-stage gear set in the transmission box 5. In this way, the high-speed and low-torque driving mechanism is reduced in speed by the gear set to form a low-speed and high-torque, thereby efficiently driving the second gear to rotate, and then driving the connecting tube 52 to rotate on the base 1 and the fixed rod 2.
