Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically a floor-standing LED lamp. Background Technology

[0002] Many people choose LED desk lamps when working or studying. However, the existing LED desk lamps have relatively traditional and outdated structural designs and light distribution methods, which have many defects. They are prone to creating a large brightness ratio, which can cause glare to people's eyes. A large brightness ratio can also make it difficult to adapt and cause visual fatigue.

[0003] Existing technologies also include some solutions for lighting fixtures. For example, a Chinese patent with application number CN201920855702.6 discloses an LED tabletop and floor lamp, which includes a base that can stand on a table or the ground, a lamp body with a hollow internal structure, a connecting structure connecting the lamp body and the base, and lamp body caps installed at both ends of the lamp body. The upper surface of the lamp body has several light-emitting chambers with openings facing different directions. The bottom of the light-emitting chamber is set as an inclined surface, and the inclination angle of the inclined surface at the bottom of each light-emitting chamber is different. The angle between the inclined surface and the horizontal plane is set between 0 degrees and 90 degrees. An LED light source structure is installed on the inclined surface, so that the LED light source structure emits light at different angles, thereby making the light emission comprehensive and achieving a shadowless lighting effect. The LED tabletop and floor lamp also includes a light-transmitting cover installed on the lamp body, a driving device installed in the hollow structure of the lamp body, an outward-leading wire plug on the base, and a control switch on the base or the wire plug. The wire leading out of the driving device passes through the connecting structure and is electrically connected to the wire plug.

[0004] However, in existing technologies, floor lamps are placed stably on the ground by a bottom counterweight plate. However, due to the need for stability, the counterweight plate requires a large weight and a large area, which often causes a lot of impurities and dust to accumulate in the gap between the outer edge of the counterweight plate and the ground. Indoor automatic sweeping robots cannot complete the cleaning task of the outer edge of the counterweight plate very well, so when cleaning is needed, the lamp must be moved manually and wiped and cleaned, which is time-consuming and laborious.

[0005] Therefore, the present invention provides a floor-standing LED lamp. Summary of the Invention

[0006] To address the shortcomings of existing technologies and solve the problem that while floor lamps are stably placed on the ground using a bottom counterweight plate, the stability requirements necessitate a large weight and floor space for the counterweight plate. This often results in the accumulation of impurities and dust in the gap between the outer edge of the counterweight plate and the ground. Indoor robotic vacuum cleaners cannot effectively clean the outer edge of the counterweight plate, requiring manual movement of the lamp and wiping and cleaning when needed, which is time-consuming and laborious. Therefore, this invention proposes a floor-standing LED lamp.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A floor-standing LED lamp, comprising a lamp body, a lamp post, and a lamp holder; a protective cover with an opening facing downwards is fitted on the top of the lamp holder, and the lamp post passes through the protective cover and is slidably connected to it; a set of electric push rods are evenly distributed between the top of the lamp holder and the protective cover, and the electric push rods are connected to a power source via a controller; a ring-shaped curtain is fixedly connected to the bottom of the protective cover near its inner circumference, and a set of trigger units are evenly distributed on the bottom of the protective cover outside the curtain, and the trigger units are connected to the controller via wires; In operation, existing floor-standing lamps are stably placed on the ground by a bottom counterweight plate, but due to the stability requirements, the counterweight plate needs a large weight and floor space, causing a lot of impurities and dust to accumulate in the gap between the outer edge of the counterweight plate and the ground. Indoor automatic sweeping robots... The original design couldn't effectively clean the outer edge of the counterweight plate, requiring manual movement of the lamp and wiping and cleaning when needed, which was time-consuming and laborious. This invention addresses this by using a protective cover that slides onto the top of the lamp base, along with a curtain, to seal the gap between the lamp base's outer edge and the ground. This reduces dust and water seepage into the corresponding bottom plate of the lamp base. Simultaneously, when a robotic vacuum cleaner passes by, the rotating brush near the bottom triggers a unit, which in turn raises the protective cover. The robotic vacuum cleaner then cleans the dust remaining between the curtain and the lamp base, and wipes away water stains caused by mopping at the contact point between the curtain and the ground. This improves the cleaning effect of the lamp base area, reduces the labor intensity of manual movement, further ensures the cleanliness of the lamp location, and reduces the growth of bacteria and viruses indoors.

[0008] Preferably, the triggering unit includes a sliding rod and a sliding hole; the sliding rod passes through the sliding hole at the bottom of the protective cover and is slidably connected to the sliding hole, and a sliding cavity with a diameter larger than the sliding hole is opened at one end of the sliding hole near the inside of the protective cover; a disk is fixedly connected to one end of the sliding rod located in the sliding cavity, and a set of arc-shaped spring pieces are evenly distributed on the top of the disk, and a contact ball is fixedly connected to the top of the spring pieces; a contact ring is fixedly connected in the sliding cavity at the position corresponding to the contact ball, and the contact ring and the contact ball are both connected to the controller through wires; a set of arc-shaped blades are evenly distributed around the bottom circumference of the sliding rod; when the brush bristles of the sweeping robot near the bottom rotate continuously, they actuate the blades and the sliding rod to rotate, thereby driving the disk to rotate continuously, causing the spring pieces and the contact ball to swing towards the contact ring under the action of centrifugal force, so that the contact ball contacts the contact ring and conducts the circuit, which facilitates sensitive reception of information that the sweeping robot is approaching the lamp holder, and then controls the electric push rod to lift the protective cover in time, increasing the cleaning effect on the bottom of the lamp holder.

[0009] Preferably, a magnet is fixed to the side of the blade near the free end, the magnets between adjacent slide rods attract each other, and the blade ends between adjacent slide rods overlap each other; by the magnets between adjacent slide rods attracting each other, when the blade is not touched and rotated by the sweeping robot, the blades between adjacent slide rods attract each other and overlap, thereby increasing the sealing effect between the blade and the curtain, further reducing the accumulation of dust, and ensuring the cleaning effect of the floor.

[0010] Preferably, the disc is a magnetic disc; a magnetic ring is fixedly connected to the bottom of the sliding cavity, and the sliding rod passes through the magnetic ring and is slidably connected to the magnetic ring; the magnetic ring and the side adjacent to the disc have the same magnetic poles; an insulating gasket is fixedly connected to the bottom of the contact ring; by magnetically repelling the disc, the disc causes the sliding rod to suspend in the sliding hole, further reducing the rotational resistance of the sliding rod, increasing the rotational sensitivity of the sliding rod when the brush of the sweeping robot touches the blade, further improving the lifting efficiency of the protective cover, and increasing the cleaning effect on the ground under the lamp holder.

[0011] Preferably, the lamp holder has a water storage cavity with a closed water inlet at the top; an ultrasonic atomizer is fixedly connected inside the water storage cavity, and the spray hole in the middle of the lamp post is connected to the ultrasonic atomizer through a pipe; the water in the water storage cavity is atomized by the ultrasonic atomizer and sprayed out from the spray hole, further increasing the indoor air humidity, reducing the dryness of indoor air due to prolonged use of air conditioning in winter or summer, and increasing the suitability of indoor air. At the same time, the water storage cavity can effectively reduce the transportation weight of the lamp and reduce transportation costs. Adding water to the water storage cavity increases the weight of the lamp holder, further improving the stability of the lamp.

[0012] Preferably, a set of suction cups are evenly distributed around the bottom circumference of the lamp holder, and a connecting rod fixed to the top of the suction cups passes through the lamp holder and extends into the water storage cavity; the connecting rod is slidably and sealed to the lamp holder; a limiting plate is fixed to the top of the connecting rod, and a compression spring is sleeved on the connecting rod between the limiting plate and the inner wall of the water storage cavity; by adsorbing the ground with the suction cups, the accidental tipping of the lamp is further reduced. At the same time, by connecting rod and compression spring, when the lamp is slightly impacted, one side of the lamp holder tilts up at a small angle, causing one side of the lamp holder to disengage from the ground at a small angle. At this time, the limiting plate and compression spring compress the sliding rod relative to the lamp holder and slide downward a certain distance, preventing the suction cups from quickly disengaging from the ground. After the impact is completed, the lamp holder is quickly straightened and reset by the reset of the compression spring, further increasing the stability of the lamp and reducing the threat of damage and injury caused by the lamp tipping over.

[0013] Preferably, the suction cup has a blind hole, and a rod is slidably connected inside the blind hole. A spring is fixed between the rod and the bottom of the blind hole. A conductive block is fixed to the top of the rod, and a conductive ring is embedded in the inner wall of the blind hole near the bottom. The top of the suction cup is connected to a vacuum pump via an air pipe, and the vacuum pump is connected to a power source via a controller. The conductive ring and the conductive block are connected to the controller via wires. When the suction cup is adhered to the ground for a long time, air leakage at the bottom of the suction cup may occur, reducing the adhesion and fixation effect between the suction cup and the ground. When the suction cup leaks air, the suction cup deforms and the lamp holder is raised one end. Then, the rod slides downward relative to the connecting rod, and the conductive block contacts the conductive ring, controlling the vacuum pump to evacuate the suction cup, further increasing the adhesion between the suction cup and the ground and increasing the stability of the lamp.

[0014] Preferably, a negative pressure hole is provided at the top of the water storage chamber, and a one-way valve is provided inside the negative pressure hole; the negative pressure hole is connected to the air pipe through a pipe; as the water in the water storage chamber is continuously consumed by the ultrasonic atomizer, the air pressure in the water storage chamber is reduced, and then the suction cup is evacuated through the negative pressure hole, further increasing the suction cup's adsorption effect on the ground.

[0015] Preferably, the suction cup has a ring-shaped absorbent sponge around its bottom periphery; the connecting rod has a first hole communicating with the water storage chamber, and the first hole is filled with multiple strands of cotton thread. The bottom end of the cotton thread is split and extends into the absorbent sponge and is fixedly connected to the absorbent sponge; through the capillary action of the cotton thread, the water in the water storage chamber is continuously and slowly transported to the absorbent sponge, so that the absorbent sponge maintains a certain level of moisture, thereby keeping the lower edge of the suction cup moist with the ground, further increasing the long-term stable sealing between the suction cup and the ground, and reducing air leakage from the suction cup.

[0016] Preferably, the top of the cotton thread passes through the first hole and is fixedly connected to the top of the water storage cavity, and the cotton thread is wrapped with an elastic rope; by fixing the cotton thread to the top of the water storage cavity, when the lamp is slightly bumped and shaken, the cotton thread slides in the first hole, which further increases the water conveyance efficiency of the cotton thread, increases the adsorption effect of the suction cup, and reduces the suction cup from falling off the ground.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The floor-standing LED lamp of this invention uses a protective cover that slides on the top of the lamp holder to seal the gap between the outer edge of the lamp holder and the ground, reducing the penetration of dust and water stains into the bottom plate of the lamp holder. Simultaneously, when a robotic vacuum cleaner passes by, the rotating brush near the bottom of the vacuum cleaner triggers a unit, which in turn controls the protective cover to rise. The robotic vacuum cleaner then cleans the dust remaining between the curtain and the lamp holder, and wipes away water stains caused by mopping at the contact point between the curtain and the ground. This improves the cleaning effect of the lamp holder area, reduces the labor intensity of manual handling, further ensures the cleanliness of the lamp holder location, and reduces the growth of indoor bacteria and viruses.

[0019] 2. The floor-standing LED lamp of the present invention uses the capillary action of cotton thread to continuously and slowly transport water in the water storage chamber to the water-absorbing sponge, so that the water-absorbing sponge maintains a certain degree of moisture, thereby keeping the lower edge of the suction cup moist with the ground, further increasing the long-term stable sealing between the suction cup and the ground, and reducing air leakage of the suction cup.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0029] like Figures 1 to 5 As shown, the present invention provides a floor-standing LED lamp, comprising a lamp body 1, a lamp post 11, and a lamp holder 12; a protective cover 13 with an opening facing downwards is fitted on the top of the lamp holder 12, and the lamp post 11 passes through the protective cover 13 and is slidably connected to the protective cover 13; a set of electric push rods 14 are evenly distributed between the top of the lamp holder 12 and the protective cover 13, and the electric push rods 14 are connected to a power source via a controller; a ring-shaped curtain 15 is fixedly connected to the bottom of the protective cover 13 near its inner circumference, and a set of trigger units 16 are evenly distributed on the bottom of the protective cover 13 outside the curtain 15, and the trigger units 16 are connected to the controller via wires; during operation, existing floor-standing lamps are stably placed on the ground by a bottom counterweight plate, but due to the stability requirements, the counterweight plate needs to be relatively heavy and occupy a large area, which often causes a lot of impurities and dust to accumulate in the gap between the outer edge of the counterweight plate and the ground, making it difficult for indoor automatic sweeping robots to effectively clean the floor. The original method of cleaning the outer edge of the counterweight plate was not ideal, as it required manual movement of the lamp and wiping and cleaning when needed, which was time-consuming and laborious. In this case, the protective cover 13, which is slidably connected to the top of the lamp holder 12, and the curtain 15 are used to seal the gap between the outer edge of the lamp holder 12 and the ground, reducing the penetration of dust and water stains into the bottom plate of the lamp holder 12. At the same time, when the robot vacuum passes by, the brushes near the bottom of the robot vacuum continuously rotate and trigger the trigger unit 16, which in turn controls the protective cover 13 to rise. Then, the robot vacuum cleans the dust remaining between the curtain 15 and the lamp holder 12, and wipes the water stains caused by mopping at the contact point between the curtain 15 and the ground, improving the cleaning effect of the lamp holder 12, reducing the labor intensity of manual movement, further ensuring the cleanliness of the lamp location, and reducing the growth of bacteria and viruses indoors.

[0030] The triggering unit 16 includes a slide rod 17 and a sliding hole 18; the slide rod 17 passes through the sliding hole 18 at the bottom of the protective cover 13 and is slidably connected to the sliding hole 18; the end of the sliding hole 18 near the inside of the protective cover 13 has a sliding cavity 19 with a diameter larger than the sliding hole 18; a disk 2 is fixedly connected to one end of the slide rod 17 located in the sliding cavity 19; a set of arc-shaped spring pieces 21 are evenly distributed on the top of the disk 2; a contact ball 22 is fixedly connected to the top of the spring piece 21; a contact ring 23 is fixedly connected in the sliding cavity 19 at a position corresponding to the contact ball 22; the contact ring 23 and the contact ball 22 are connected by wires. The controller includes a set of arc-shaped blades 24 evenly distributed around the bottom circumference of the slide bar 17. When the brush near the bottom of the sweeping robot rotates continuously, it causes the blades 24 and the slide bar 17 to rotate, which in turn drives the disc 2 to rotate continuously. This causes the spring 21 and the contact ball 22 to swing towards the contact ring 23 under the action of centrifugal force. This allows the contact ball 22 to make contact with the contact ring 23 and conduct the circuit, making it convenient and sensitive to receive information that the sweeping robot is approaching the lamp holder 12. This allows the controller to control the electric push rod 14 to lift the protective cover 13 in time, increasing the cleaning effect on the bottom of the lamp holder 12.

[0031] A magnet 25 is fixed to one side of the blade 24 near its free end. The magnets 25 between adjacent slide bars 17 attract each other, and the ends of the blades 24 between adjacent slide bars 17 overlap each other. By attracting each other through the magnets 25 between adjacent slide bars 17, when the blades 24 are not rotated by the sweeping robot, the blades 24 between adjacent slide bars 17 attract each other and overlap, thereby increasing the sealing effect between the blades 24 and the curtain 15, further reducing the accumulation of dust, and ensuring the cleaning effect of the floor.

[0032] The disc 2 is a magnetic disc; a magnetic ring 26 is fixedly connected to the bottom of the sliding cavity 19, and the sliding rod 17 passes through the magnetic ring 26 and is slidably connected to the magnetic ring 26; the magnetic ring 26 and the side adjacent to the disc 2 have the same magnetic poles; an insulating gasket is fixedly connected to the bottom of the contact ring 23; by magnetically repelling the disc 2, the disc 2 causes the sliding rod 17 to suspend in the sliding hole 18, further reducing the rotational resistance of the sliding rod 17, increasing the rotational sensitivity of the sliding rod 17 when the brush of the sweeping robot touches the blade 24, further improving the lifting efficiency of the protective cover 13, and increasing the cleaning effect of the ground under the lamp holder 12.

[0033] The lamp holder 12 has a water storage chamber 3, and the top of the water storage chamber 3 has a closed water inlet. An ultrasonic atomizer 31 is fixedly connected to the water storage chamber 3. The nozzle 32 in the middle of the lamp post 11 is connected to the ultrasonic atomizer 31 through a pipe. The ultrasonic atomizer 31 atomizes the water in the water storage chamber 3 and sprays it out from the nozzle 32, which further increases the indoor air humidity and reduces the dryness of the indoor air caused by prolonged use of air conditioning in winter or summer, thus increasing the suitability of the indoor air. At the same time, the water storage chamber 3 can effectively reduce the transportation weight of the lamp and reduce transportation costs. Adding water to the water storage chamber 3 increases the weight of the lamp holder 12, which further improves the stability of the lamp.

[0034] A set of suction cups 33 are evenly distributed around the bottom circumference of the lamp holder 12. A connecting rod 34 fixed to the top of the suction cups 33 passes through the lamp holder 12 and extends into the water storage cavity 3. The connecting rod 34 is slidably and sealingly connected to the lamp holder 12. A limiting plate 35 is fixed to the top of the connecting rod 34. A compression spring 36 is sleeved on the connecting rod 34 between the limiting plate 35 and the inner wall of the water storage cavity 3. By adsorbing the ground with the suction cups 33, the accidental tipping of the lamp is further reduced. At the same time, by connecting rod 34 and compression spring 36, when the lamp is slightly bumped, one side of the lamp holder 12 tilts up at a small angle, so that one side of the lamp holder 12 is slightly disengaged from the ground. At this time, the limiting plate 35 and compression spring 36 compress the sliding rod 17 relative to the lamp holder 12 and slides downward a certain distance to prevent the suction cups 33 from quickly detaching from the ground. After the collision is completed, the compression spring 36 resets the lamp holder 12 quickly and returns it to its original position, further increasing the stability of the lamp and reducing the threat of damage and injury caused by the lamp tipping over.

[0035] The suction cup 33 has a blind hole 37, and a rod 38 is slidably connected inside the blind hole 37. A spring is fixed between the rod 38 and the bottom of the blind hole 37. A conductive block 39 is fixed to the top of the rod 38, and a conductive ring 4 is embedded in the inner wall of the blind hole 37 near the bottom. The top of the suction cup 33 is connected to a vacuum pump through an air pipe 41, and the vacuum pump is connected to a power source through a controller. The conductive ring 4 and the conductive block 39 are connected to the controller through wires. When the suction cup 33 is attached to the ground for a long time, it is easy for air to leak from the bottom of the suction cup 33, reducing the adhesion and fixation effect between the suction cup 33 and the ground. When the suction cup 33 leaks air, the suction cup 33 deforms and raises the lamp holder 12 by one end. Then the rod 38 slides downward relative to the connecting rod 34, and then the conductive block 39 contacts the conductive ring 4, controlling the vacuum pump to evacuate the suction cup 33, further increasing the adhesion between the suction cup 33 and the ground and increasing the stability of the lamp.

[0036] The top of the water storage chamber 3 is provided with a negative pressure hole 42, and a one-way valve is provided inside the negative pressure hole 42. The negative pressure hole 42 is connected to the air pipe 41 through a pipe. As the water in the water storage chamber 3 is continuously consumed by the ultrasonic atomizer 31, the air pressure in the water storage chamber 3 decreases, and then the suction cup 33 is drawn through the negative pressure hole 42 to further increase the suction effect of the suction cup 33 on the ground. Example

[0037] like Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the suction cup 33 has an annular water-absorbing sponge 43 on its outer periphery at the bottom; the connecting rod 34 has a first hole 44 communicating with the water storage cavity 3, and the first hole 44 is filled with multiple strands of cotton thread 45. The bottom end of the cotton thread 45 is split and extends into the interior of the water-absorbing sponge 43 and is fixedly connected to the water-absorbing sponge 43; through the capillary action of the cotton thread 45, the water in the water storage cavity 3 is continuously and slowly transported to the water-absorbing sponge 43, so that the water-absorbing sponge 43 maintains a certain degree of moisture, thereby keeping the lower edge of the suction cup 33 moist with the ground, further increasing the long-term stable sealing between the suction cup 33 and the ground, and reducing air leakage of the suction cup 33.

[0038] The top of the cotton thread 45 passes through the first hole 44 and is fixedly connected to the top of the water storage cavity 3. An elastic rope is wrapped inside the cotton thread 45. By fixing the cotton thread 45 to the top of the water storage cavity 3, the cotton thread 45 slides in the first hole 44 when the lamp is slightly bumped and shaken, which further increases the water conveying efficiency of the cotton thread 45, increases the adsorption effect of the suction cup 33, and reduces the detachment of the suction cup 33 from the ground.

[0039] During operation, the present invention uses a protective cover 13 slidably connected to the top of the lamp holder 12, along with a curtain 15, to seal the gap between the outer edge of the lamp holder 12 and the ground, reducing dust and water seepage into the bottom plate of the lamp holder 12. Simultaneously, when a robotic vacuum cleaner passes by, the rotating brush near the bottom of the vacuum cleaner triggers a trigger unit 16, which in turn controls the protective cover 13 to rise. The robotic vacuum cleaner then cleans the dust remaining between the curtain 15 and the lamp holder 12, and wipes away water stains caused by mopping at the contact point between the curtain 15 and the ground, improving the cleaning effect of the lamp holder 12 area, reducing the labor intensity of manual handling, and further ensuring the cleanliness of the lamp location. This reduces the growth of bacteria and viruses indoors. When the brush bristles near the bottom of the robot vacuum rotate, they cause the blades 24 and slide bars 17 to rotate, which in turn drives the disc 2 to rotate. This causes the spring 21 and contact ball 22 to swing towards the contact ring 23 under centrifugal force. This allows the contact ball 22 to contact the contact ring 23, activating the circuit and facilitating sensitive reception of the robot vacuum's approach to the light holder 12. This, in turn, controls the electric push rod 14 to promptly lift the protective cover 13, increasing the cleaning effect on the bottom of the light holder 12. Furthermore, the magnets 25 between adjacent slide bars 17 attract each other, causing the blades 24 to overlap and interact even when not activated by the robot vacuum, thus increasing the cleaning efficiency of the blades 24. The sealing effect of the curtain 15 on the ground further reduces dust accumulation and ensures effective floor cleaning. The magnetic repulsion of the disc 2 causes the disc 2 to suspend the slide rod 17 within the sliding hole 18, further reducing the rotational resistance of the slide rod 17 and increasing its rotational sensitivity when the robot vacuum brushes touch the blades 24. This further improves the lifting efficiency of the protective cover 13 and enhances the cleaning effect on the floor beneath the lamp holder 12. The ultrasonic atomizer 31 atomizes the water in the water storage chamber 3 and sprays it out from the nozzle 32, further increasing indoor air humidity and reducing the dryness caused by prolonged air conditioning use in winter or summer, thus increasing indoor air comfort. Simultaneously, the water storage chamber 3 effectively reduces the transportation costs of the lamps. The weight is reduced, and transportation costs are lowered. By adding water to the water storage chamber 3, the weight of the lamp holder 12 is increased, further improving the stability of the lamp. The suction cup 33 adheres to the ground, further reducing the risk of accidental tipping of the lamp. At the same time, through the linkage 34 and the compression spring 36, when the lamp is slightly impacted, one side of the lamp holder 12 tilts up at a small angle, causing one side of the lamp holder 12 to disengage from the ground at a small angle. At this time, the limiting plate 35, in conjunction with the compression spring 36, causes the sliding rod 17 to slide downward relative to the lamp holder 12 a certain distance, preventing the suction cup 33 from quickly disengaging from the ground. After the impact is completed, the compression spring 36 resets the lamp holder 12 quickly, further increasing the stability of the lamp and reducing the threat of damage and injury caused by tipping of the lamp.When the suction cup 33 adheres to the ground for an extended period, air leakage at the bottom of the suction cup 33 can occur, reducing its adhesion and fixation effect. When the suction cup 33 leaks air, it deforms, causing the lamp holder 12 to rise slightly. Then, the insertion rod 38 slides downwards relative to the connecting rod 34, causing the conductive block 39 to contact the conductive ring 4. This then controls the vacuum pump to evacuate the suction cup 33, further increasing its adhesion to the ground and enhancing the lamp's stability. Simultaneously, the water in the water storage chamber 3 is continuously consumed by the ultrasonic atomizer 31, reducing the air pressure within the chamber. This, in turn, evacuates the suction cup 33 through the negative pressure hole 42, further enhancing its adhesion to the ground.
