[0049] Referring to Figure 4 In some embodiments, the air inlet can be provided on the top shell 110, of course, the air inlet can also be provided on the bottom plate 120, or the air inlet can be provided on both the top shell 110 and the bottom plate 120 to improve the inflation efficiency.

[0050] In some embodiments, the outer surface of the shell 210 is provided with an adhesive layer, and the adhesive layer has an adhesive. The shell 210 is attached to the outer surface of the bottom plate 120 through the adhesive layer, which facilitates the connection of the suction accessory 20 and the bottom plate 120.

[0051] In some other embodiments, the shell 210 can also be press-fitted to the outer surface of the bottom plate 120 to form an integrated structure with the bottom plate 120, so that the connection of the suction accessory 20 and the bottom plate 120 is more stable, and the suction accessory 20 will not be separated from the bottom plate 120.

[0052] In some embodiments, the shell 210 comprises an open-ended outer shell 211 and a cover plate 212. The cover plate 212 is located inside the bottom plate 120, the outer shell 211 is located outside the bottom plate 120, and the open end of the outer shell 211 faces the bottom plate 120. The cover plate 212 is fixedly connected through bolt fasteners passing through the bottom plate 120 and the open end of the outer shell 211, thereby fixing the bottom plate 120 between the cover plate 212 and the outer shell 211. The cover plate 212 and the outer shell 211 are fixed together by the bottom plate 120, so that the shell 210 and the bottom plate 120 are integrated, and the connection between the shell 210 and the bottom plate 120 is more secure. The bolt fasteners can be screws, and the bottom plate 120, the cover plate 212, and the open end of the outer shell 211 can correspondingly be provided with screw holes, and the screws can be screwed into the screw holes to fixedly connect the bottom plate 120, the cover plate 212, and the outer shell 211. The vacuumizing device 230 is arranged in the outer shell 211 and located in the space between the bottom plate 120 and the outer shell 211. The through hole is arranged on the outer wall of one end of the outer shell 211 away from the bottom plate 120.

[0053] In some embodiments, a plurality of suction accessories 20 are arranged around the outer edge of the bottom plate 120 to enable the bottom plate 120 to be flatly adsorbed to the external support surface.

[0054] Specifically, when the air cushion lamp needs to be installed, the user only needs to align the bottom plate 120 of the air cushion lamp with the support surface, adsorb the suction disc 220 of the suction accessory 20 to the support surface, and start the vacuumizing device 230. At this time, the plurality of suction accessories 20 can firmly adsorb the air cushion lamp to the support surface in a short time. Since the plurality of suction accessories 20 are arranged around the edge of the bottom plate 120, the weight and pressure of the air cushion lamp can be effectively dispersed, so that the air cushion lamp can be kept flat and is not prone to local loosening or unstable adsorption, thereby improving the installation and fixing effect of the air cushion lamp.

[0055] In addition, the plurality of suction accessories 20 are arranged around the outer edge of the bottom plate 120, so that air cushion lamps of various shapes such as circular, rectangular, or regular polygonal shapes can be fixed to flat wall surfaces, curtain walls, glass doors and windows, or bathroom support surfaces, greatly improving the applicability of the air cushion lamp in various shooting and living scenes.

[0056] Referring to Figure 5 In some embodiments, the lamp body 10 further comprises a heat dissipation adhesive layer 130 arranged between the lamp panel 310 and the top shell 110. The heat dissipation adhesive layer 130 is provided with a plurality of through holes, and each through hole corresponds to a lamp bead 311 on the lamp panel 310. The lamp bead 311 is arranged in the through hole.

[0057] Specifically, the heat dissipation adhesive layer 130 can be a foam adhesive layer, which has certain flexibility and plasticity, can be rolled with the top shell 110 and the bottom plate 120, and can provide certain supporting force after the lamp body 10 is inflated to ensure the flatness of the light emitting surface. The heat dissipation adhesive layer 130 can be bonded with the lamp plate 310, and can dissipate the heat on the lamp plate 310. When multiple lamp plates 310 are arranged side by side, the lamp beads 311 in the multiple lamp plates 310 are arranged on the same heat dissipation adhesive layer 130, and the heat dissipation adhesive layer 130 can shape and position the multiple lamp plates 310.

[0058] In some embodiments, the heat dissipation adhesive layer 130 is provided with a via hole, so that it does not block the light emitted outward by the lamp bead 311, and the problem of light blocking is avoided.

[0059] In some embodiments, the lamp body 10 further comprises a sealing adhesive layer 140. The sealing adhesive layer 140 is arranged between the bottom plate 120 and the lamp plate 310, the two side surfaces of the sealing adhesive layer 140 are bonded with the bottom plate 120 and the lamp plate 310 respectively, and the space between the sealing adhesive layer 140 and the top shell 110 forms a cavity 111. When the bottom plate 120 is made of cloth, the bottom plate 120 itself has small holes, and the bottom plate 120 can be isolated by arranging the sealing adhesive layer 140, thereby enhancing the air tightness of the cavity 111 and preventing air from leaking from the bottom plate 120.

[0060] In some embodiments, the two side surfaces of the sealing adhesive layer 140 are bonded with the bottom plate 120 and the lamp plate 310, and the heat of the lamp plate 310 can be directly transmitted to the bottom plate 120 and dissipated to the external environment through the bottom plate 120, thereby further improving the heat dissipation capacity of the air cushion lamp.

The lamp panel 310 is pressed between the air cushion bottom layer 160 and the cover film layer 170, and the air cushion bottom layer 160 and the top shell 110 are tightly sealed, so that the lamp panel 310 is pressed tightly by the air cushion bottom layer 160 and the cover film layer 170, and the lamp panel 310 is positioned by the cover film layer 170. The cover film layer 170 can be transparent to facilitate light passing through the cover film layer 170.

[0064] In some other embodiments, the bottom plate 120 is connected to the side of the air cushion bottom layer 160 away from the lamp panel 310. The space between the air cushion bottom layer 160 and the top shell 110 forms a cavity 111, and the air cushion bottom layer 160 tightly seals one end of the cavity 111 to improve the sealing effect. In this case, the air inlet can be provided on the top shell 110, and the air nozzle 100 is in communication with the cavity 111 through the air inlet on the top shell 110 to facilitate the inflation and deflation of the cavity 111. The air cushion bottom layer 160 can be a light-blocking material or have a light-reflecting layer on the side facing the top shell 110. In another example, the suction accessory 20 can also be directly attached to the back of the air cushion bottom layer 160 to achieve the function of the bottom plate 120.

[0065] In some other embodiments, the lamp panel 310 can also be a double-sided lamp panel, which has lamp beads on both sides facing the air cushion bottom layer 160 and the top shell 110, and the air cushion bottom layer 160 is a light-transmissive material. The suction accessory 20 can be attached to the back of the air cushion bottom layer 160, so that the lamp body 10 can emit light in multiple directions. When the air cushion lamp is used as a photography lamp, it can create a special light atmosphere. When the air cushion lamp is used for light therapy and beauty, the user can use the suction accessory to attach the lamp body 10 to the bathroom wall, so that the light shines from the top shell 110 to the human body, or use the suction accessory to attach the lamp body 10 to the surface of the human body, so that the light shines from the air cushion bottom layer 160 to the surface of the human body, which can meet the needs of different scenarios and different customers.

The starting piece 250 has a gap between the air suction hole 221 and the hole wall of the through hole. One end of the starting piece 250 protrudes out of the air suction hole 221 and can abut against the surface of the device when the suction cup 220 adsorbs the external device. The other end of the starting piece 250 is connected with the vacuumizing device 230, and the connection mode can be electrical connection or physical connection. The starting piece 250 is configured to control the vacuumizing device 230 to start when it is abutted by the device into the shell 210. After the vacuumizing device 230 starts, the air in the air chamber can be exhausted, so that the outer surface of the suction cup 220 generates negative pressure to adsorb the device on the suction cup 220.

[0073] In some embodiments, by arranging the starting piece 250, the starting of the vacuumizing device 230 can be automatically controlled in real time by using the situation that the device adsorbs the suction cup 220 and simultaneously abuts against the starting piece 250, so as to avoid manual starting of the vacuumizing device 230, improve the automation of the suction accessory 20, and improve the user experience.

[0074] In some embodiments, the starting piece 250 includes a main body 251 and a convex column 253 protruding from one side of the main body 251. The main body 251 and the convex column 253 have elasticity and can be elastically deformed when pressed. The main body 251 and the convex column 253 can be made of rubber or liquid silicone. The main body 251 is clamped between the air passage partition plate 240 and the inner wall of the through hole of the shell 210 and is supported and limited by the air passage partition plate 240 and the inner wall of the shell 210. The convex column 253 is arranged in the through hole and the air suction hole 221, and the end of the convex column 253 away from the body protrudes out of the air suction hole 221 and is used to abut against the external device.

[0075] In some embodiments, since the main body 251 and the convex column 253 have elasticity, when the device abuts against the convex column 253 into the shell 210, the convex column 253 and the main body 251 elastically contract into the shell 210, the convex column 253 and the main body 251 are displaced in the axis direction of the through hole, and the main body 251 controls the starting of the vacuumizing device 230.

[0076] In some embodiments, in order to provide a larger contraction space for the main body 251 and the convex column 253 and make the device more easily abut against the starting piece 250 into the shell 210, a recessed part 252 can be arranged on the side of the main body 251 opposite to the convex column 253. The bottom surface of the recessed part 252 has a gap with the air passage partition plate 240, so as to form a space for the convex column 253 to contract into the shell 210.

[0077] In some embodiments, the part of the ventilation baffle 240 corresponding to the recess 252 can be hollowed out, so that the space in which the convex column 253 is retracted into the shell 210 is larger, and at the same time, the main body 251 can be connected to the vacuum device 230. It should be noted that the area of the main body 251 outside the recess 252 abuts against the ventilation baffle 240, at which time the air chamber is annular and is arranged around the recess 252 to avoid air leakage in the air chamber.

[0078] In some embodiments, a gas pressure or gas sensitive element can be arranged at the hollowed-out part of the recess 252 or the ventilation baffle 240, and the gas pressure or gas sensitive element is electrically connected to the vacuum device 230. When the convex column 253 is retracted into the shell 210 by being abutted by the equipment, the bottom surface of the recess 252 of the main body 251 is deformed to be concave inward, so that the airflow or gas pressure at the hollowed-out part of the recess 252 and the ventilation baffle 240 changes. After the gas pressure or gas sensitive element detects the change in airflow or gas pressure, it can generate a corresponding start signal and transmit it to the vacuum device 230, so as to control the vacuum device 230 to start.

[0079] In some embodiments, a pressure switch can also be arranged in the recess 252, one end of the pressure switch abuts against or maintains a certain distance from the bottom surface of the recess 252. When the convex column 253 is retracted into the shell 210 by being abutted by the equipment, the bottom surface of the recess 252 abuts against the pressure switch, and the pressure switch outputs a start signal to the vacuum device 230 to control the vacuum device 230 to start.

[0080] In some embodiments, a mechanical switch can also be arranged in the recess 252, one end of the mechanical switch is in contact with or maintains a certain distance from the bottom surface of the recess 252, and the other end of the mechanical switch is connected to the start key of the vacuum device 230. When the convex column 253 is retracted into the shell 210 by being abutted by the equipment, the bottom surface of the recess 252 moves the mechanical switch, thereby directly controlling the vacuum device 230 to start.

[0081] In some embodiments, the inner wall of the through hole of the shell 210 is provided with a third ring stopper 214, and the third ring stopper 214 is located in the second ring stopper 213. One side of the main body 251 provided with the convex column 253 is provided with a first ring groove 254, and the first ring groove 254 and the third ring stopper 214 are coaxial, so that the third ring stopper 214 is clamped in the first ring groove 254, which can further limit the position of the main body 251. The first ring groove 254 can also be coaxial with the convex column 253.

[0082] In some embodiments, the first ring groove 254 has two opposite groove walls, one of which extends towards the second ring stop 213 and abuts against the inner side of the second ring stop 213, and the other of which is provided with an opening, which is in communication with the through hole, so as to be in communication with the air outlet of the vacuumizing device 230. The third ring stop 214 is provided with a through hole in communication with the opening. When the device abuts against the convex column 253 and the main body 251 is elastically retracted into the shell 210, the other of the two groove walls, which is close to the convex column 253, forms a gap with the third ring stop 214, and the gap is in communication with the through hole, so that the vacuumizing device 230 can exhaust the air between the outer surface of the suction cup 220 and the device, and the outer surface of the suction cup 220 forms a negative pressure to adsorb the device.

[0083] In some embodiments, the portion of the one of the two groove walls, which extends towards the second ring stop 213, is provided with a notch, and the second ring stop 213 is provided with a clamping portion which is clamped into the notch. By clamping the clamping portion into the notch, the position between the main body 251 and the shell 210 can be positioned, so that after installation, the opening is in communication with the through hole opposite to each other. At the same time, by clamping the clamping portion into the notch, the connection between the main body 251 and the shell 210 can be more firm.

[0084] In some embodiments, since the main body 251 and the convex column 253 are elastic, when the convex column 253 is elastically retracted into the shell 210, the main body 251 is retracted to the side of the ventilation partition plate 240, so that the third ring stop 214 and the other of the two groove walls, which is close to the convex column 253, form a larger gap. The gap can be in communication with the through hole and the air inlet hole 221 through the gap between the main body 251 and the inner wall of the shell 210 at this time, so that the vacuumizing device 230 can exhaust the air in the space between the outer surface of the suction cup 220 and the device. It should be noted that when the convex column 253 is not abutted by the device, the main body 251 is tightly attached between the ventilation partition plate 240 and the inner wall of the shell 210 by its own elasticity, and the third ring stop 214 and the groove wall are tightly attached together. At this time, the through hole is not in communication with the outside, and the air chamber is sealed.

[0085] In some embodiments, the fourth ring barriers 222 are arranged on one side of the suction plate 220 facing the shell 210, and the second ring grooves 215 are arranged on one side of the shell 210 facing the suction plate 220, and the fourth ring barriers 222 are correspondingly clamped in the second ring grooves 215, so that the sealing between the suction plate 220 and the shell 210 in the direction parallel to the outer wall of the shell 210 is improved, and the air at the through hole can hardly leak from the space between the second ring grooves 215 and the fourth ring barriers 222, so that the air in the space between the outer surface of the suction plate 220 and the equipment can be effectively extracted by the vacuum device 230 during operation. In the embodiment, the fourth ring barriers 222 and the second ring grooves 215 can be arranged in pairs, and the fourth ring barriers 222 and the second ring grooves 215 can be coaxial with the convex column 253.

[0086] In some embodiments, the fourth ring barriers 222 can also be arranged on one side of the shell 210 facing the suction plate 220, and the second ring grooves 215 can be arranged on one side of the suction plate 220 facing the shell 210.

[0087] In some embodiments, the suction plate 220 includes a base 223, an outer connecting disc 225 extending from the edges of the base 223 to opposite sides, and a mounting disc 224 for sealingly covering the outer end of the through hole, and the fourth ring barriers 222 can be arranged on one side of the mounting disc 224 facing the shell 210. The edge of the mounting disc 224 can be provided with a fifth ring barrier extending towards the outer wall of the shell 210, and the outer wall of the shell 210 can be provided with a third ring groove 216 matched with the fifth ring barrier, so that the fifth ring barrier is clamped in the third ring groove 216 during installation, and the mounting disc 224 and the outer wall of the shell 210 are firmly connected.

[0088] Meanwhile, the outer connecting disc 225 is used for adsorbing on the equipment, and in the direction from the edge of the base 223 to the edge of the outer connecting disc 225, the outer connecting disc 225 gradually moves away from the mounting disc 224, so that the distance between the edge of the outer connecting disc 225 and the edge of the mounting disc 224 is the largest, and thus the outer surface of the outer connecting disc 225 is formed as an arc surface with a certain curvature. When the outer connecting disc 225 is adsorbed on the equipment, the edge of the outer connecting disc 225 can abut against the surface of the equipment, and the base 223 is spaced apart from the surface of the equipment, so that the base 223 and the outer connecting disc 225 can form a sealed space with the surface of the equipment. After the vacuum device 230 is started, the air in the sealed space can be extracted, so that a negative pressure is formed to firmly adsorb the equipment on the outer connecting disc 225. The air suction hole 221 penetrates the base 223.

[0089] In some embodiments, the outer disc 225 can be made of liquid silicone or rubber, which has a certain elasticity. The outer disc 225 and the mounting disc 224 have a certain distance, so that the outer disc 225 can be deformed when being abutted by the device, and can be firmly adsorbed on the surface of the device.

[0090] In some embodiments, the base 223, the outer disc 225 and the mounting disc 224 can be integrally formed and have a certain elasticity.

[0091] In some embodiments, when the device needs to be removed from the suction cup 220, the edge of the suction cup 220 can be manually spread to allow external air to enter the space between the suction cup 220 and the device, so that the space is balanced with the external air pressure, and the device can be separated from the suction cup 220.

[0092] Referring to FIG. 1, in some embodiments, in order to improve the user experience, a pressure relief member 260 can be provided to help the device to be removed from the suction cup 220. The air outlet of the vacuum device 230 is communicated with the air duct through the air pipe 263, so that the vacuum device 230 can exhaust the gas in the air duct. The pressure relief member 260 is arranged on the air pipe 263, and can communicate the air duct with the external environment to balance the air pressure of the air duct and the external environment, so that the negative pressure state of the outer surface of the suction cup 220 is released, and the suction cup 220 can be easily removed from the device.

[0093] In some embodiments, the pressure relief member 260 includes a pressure relief valve 261 and a pressure relief switch 262, and the air pipe 263 includes a first pipe and a second pipe. The air outlet of the vacuum device 230 is communicated with the pressure relief valve 261 through the first pipe, and the pressure relief valve 261 is communicated with the through hole through the second pipe. Specifically, the pressure relief valve 261 can be communicated with the communication hole. The pressure relief switch 262 is connected with the pressure relief valve 261 to open and close the pressure relief valve 261. When the pressure relief switch 262 closes the pressure relief valve 261, the air outlet of the vacuum device 230 forms a closed air path through the first pipe and the second pipe. After the vacuum device 230 is started, the air in the air duct, i.e., the air chamber, can be exhausted, so that the outer surface of the suction cup 220 forms a negative pressure to adsorb the device.

[0094] When the pressure relief switch 262 opens the pressure relief valve 261, the air outside the pressure relief valve 261 can enter the pressure relief valve 261 to fill the air duct, so that the pressure difference between the air duct and the external environment becomes smaller until zero, so that the negative pressure of the outer surface of the suction cup 220 disappears, the suction force of the suction cup 220 to the device disappears, and the device can be easily separated from the suction cup 220, thereby avoiding the device to be manually and laboriously removed from the suction cup 220, and improving the user experience.

[0095] It should be noted that the pressure relief valve 261 can be a three-way valve, the first pipeline, the second pipeline and the pressure relief switch 262 are connected with the openings of the pressure relief valve 261, and the pressure relief switch 262 can control whether the pressure relief valve 261 is communicated with the outside.

[0096] In some embodiments, one end of the pressure relief switch 262 extends out of the shell 210, and the end extending out of the shell 210 is a control end of the pressure relief switch 262. An external force presses the pressure relief switch 262, so as to control the opening and closing of the pressure relief valve 261. When the pressure relief switch 262 opens the pressure relief valve 261, the air in the shell 210 can enter the pressure relief valve 261, or the air outside the shell 210 can enter the pressure relief valve 261 through the pressure relief switch 262.

[0097] In some embodiments, the suction accessory 20 further comprises a circuit board 264 and an air pressure sensor 265, the vacuumizing device 230 and the air pressure sensor 265 are electrically connected with the circuit board 264, the air pressure sensor 265 is used for detecting the air pressure in the air channel, and the circuit board 264 is used for controlling the vacuumizing device 230 to operate according to the detection value of the air pressure sensor 265. When the air pressure in the air channel changes due to the sealing between the suction cup 220 and the outer wall of the shell 210, and the air channel cannot maintain a negative pressure state, the air pressure sensor 265 transmits the detected detection value to the controller on the circuit board 264, and the controller of the circuit board 264 can send a control signal to the vacuumizing device 230 to make the vacuumizing device 230 operate, continue to extract the air in the air channel, and maintain the negative pressure state in the air channel to maintain the suction force of the suction cup 220 on the device.

[0098] In some embodiments, the detection end of the air pressure sensor 265 can extend into the pressure relief valve 261 to detect the change of the air pressure in the air channel.

[0099] In some embodiments, the vacuumizing device 230 can be a gas pump, and the air inlet of the gas pump is the air outlet of the vacuumizing device 230. The air outlet of the gas pump can be provided with a gas flange 231, and the gas flange 231 is a soft silica gel flange structure and is closed in a normal state. When the gas pump extracts air, the gas flow pushes away the gas flange 231 to exhaust air.

[0100] In summary, the air cushion lamp provided by the present application comprises an inflatable lamp body 10, a light source 30 arranged in the lamp body 10 and a suction accessory 20. The suction accessory 20 forms a negative pressure by extracting the air on the outer surface of the suction cup 220 through the vacuumizing device 230 in the shell 210, so that the lamp body 10 can be adsorbed on the external supporting surface through the suction cup 220. The adsorption function of the suction cup 220 of the suction accessory 20 can enable the air cushion lamp to be quickly and stably adsorbed on the supporting surface or the device. The operation process is simple and fast, which saves the time and energy of the user and improves the use convenience and installation efficiency of the air cushion lamp.
