Description

Technical field:

[0001] The utility model relates to a quilt drying device installed at the head of a bed, which is a bracket of an ultraviolet lamp and a control circuit. Background technology:

[0002] There are two ways to dry quilts: outdoor drying and balcony drying. Outdoor drying works best when the weather is fine, but the disadvantage is that it is easy to get wet in the rain if the weather changes, so it is only suitable for families with people at home all the time. Balcony drying is not as effective because the quilt will not be fully exposed to the sun, and there is still a risk of being hit by rain when the window is open. When the window is closed, the effect is greatly reduced because ultraviolet rays cannot pass through the glass. Summary of the invention:

[0003] In order to overcome the above disadvantages, the utility model discloses a bedside quilt drying device, which can dry the quilt by laying the quilt flat on the bed. The principle is to install two movable ultraviolet lamps at the bedside, which are usually folded on the wall on one side of the bedside, unfolded and placed in the center of the bed when in use, and turned on at a fixed time. After the quilt is irradiated by the ultraviolet lamp for a period of time, the sterilization and mite removal effect is better than the outdoor drying effect. Its structure is: in the center line direction of the bed, on the wall on one side of the bedside, at a height of 0.6 to 1.5 meters from the bed surface, a support is fixedly installed, a first joint is fixedly connected in front of the support, a vertical rotatable shaft is arranged in the first joint, a first ultraviolet lamp fixedly connected to the shaft and capable of swinging left and right is arranged in front, a second joint is arranged at the tail end of the lamp, and the second joint also has a vertical shaft, the upper end of the joint is fixedly connected to the tail end of the first ultraviolet lamp, and the lower end is fixedly connected to one end of the second ultraviolet lamp, so that the two ultraviolet lamps can be folded together one up and one down when not in use, and flatly attached to the wall.

[0004] Because ultraviolet rays are harmful to human eyes and skin, when the ultraviolet lamp of the utility model is turned on, no one is allowed to be in the room. To ensure safety, the utility model ensures safety from two aspects in circuit design: first, an infrared sensor is installed. When the utility model is powered on, if the infrared sensor senses that there is someone in the room, it will automatically cut off the power supply of the two ultraviolet lamps. After the person in the room leaves, the two ultraviolet lamps will be powered on after a delay. Second, in order to prevent children from opening the door and not entering the room, and seeing the glowing ultraviolet lamp outside, the utility model also installs a door magnetic switch composed of a reed switch and a magnet on the bedroom door frame. Only when the bedroom door is completely closed can the ultraviolet lamp be powered on. As long as the bedroom door is opened even a crack, the ultraviolet lamp will be immediately powered off. The two switches logically form an "and" (circuit equivalent to series) relationship, thereby ensuring safety.

[0005] The main technical features for which protection is sought in the utility model are: a first joint is installed at the front of the support, a vertical column fixedly connected to ultraviolet lamp No. 1 is installed inside the first joint, the ultraviolet lamp No. 1 can rotate horizontally, and the other end of the ultraviolet lamp No. 1 is fixedly connected to a second joint, the upper part of the second joint is fixedly connected to the ultraviolet lamp No. 1, and the lower movable part is fixedly connected to one end of the ultraviolet lamp No. 2, and the ultraviolet lamp No. 2 can rotate horizontally around the axis of the second joint.

[0006] The secondary technical features for which protection is requested by the utility model are as follows: the power plug is electrically connected to the power cord, the power cord is electrically connected to the power supply board, the power supply board is electrically connected to the computer board, the computer board is electrically connected to the switch button, the computer board is electrically connected to the indicator light, the computer board is electrically connected to the infrared sensor, the computer board is electrically connected to the control circuit, the control circuit is electrically connected to the jack, the jack is electrically connected to the plug, the plug is electrically connected to the door magnetic switch reed switch, the door magnetic magnet is used in conjunction with the door magnetic switch reed switch, the control circuit is electrically connected to the first ultraviolet lamp ballast and the second ultraviolet lamp ballast, the first ultraviolet lamp ballast and the second ultraviolet lamp ballast are electrically connected to the two ultraviolet lamp tubes, and the electrical working principle is: when the power plug is inserted into the socket, 220V mains electricity enters the power supply board through the power cord, and the power supply board provides the computer board with It is used for low-voltage direct current. A microprocessor integrated block is installed on the computer board to receive signal instructions from the switch button and infrared sensor, and send the calculation result to the control circuit. At the same time, the working status is indicated by the indicator light. The control circuit is a switch to control the on and off of the ultraviolet lamp. When in use, first move the No. 1 ultraviolet lamp and the No. 2 ultraviolet lamp to the working position in the center of the bed, plug in the power plug, and the indicator light will be always green, indicating that the power is connected and in standby mode. At this time, just press the switch button, and the indicator light will flash, indicating that the system default one-hour timing program is about to begin. When people leave the room, the indicator light will flash blue, and after 30 seconds, the indicator light will turn red. At the same time, the two ultraviolet lamps will light up together, and will go out after the timing time is up, restoring the standby mode with the indicator light always green.

[0007] The main support tube is a metal cylinder with a main support installed inside. The main support tube is fixedly connected to the support plate. An upper rocker arm is installed between the two nuts behind the main support. The hole at the big end of the upper rocker arm is sleeved on the male thread at the tail end of the main support and is clamped by two nuts to form a fixed connection. The small head is fixedly connected to the upper rod shaft, and the upper rod shaft is sleeved with a connecting rod. The circular hole at the upper end of the connecting rod is sleeved on the upper rod shaft of the upper rocker arm to form a hinge connection, and the circular hole at the lower end is sleeved on the lower rod shaft of the lower rocker arm to form a hinge connection. The small head end of the upper rocker arm is fixedly connected with a stop magnet to fix it. The stop reed switch connected to the support reinforcement plate cooperates to ensure that the main support can stop only when the ultraviolet lamp is directly below it during the shaking process; a shaking motor is also fixedly connected to the lower right side of the support reinforcement plate, and a lower rocker arm is fixedly connected to the output shaft of the shaking motor. The lower rocker arm is a plate-shaped metal part with round holes at both ends, and the big end is fixedly connected to the output shaft of the shaking motor, and the small end is riveted with a lower rod shaft, and a connecting rod is movable on the lower rod shaft; two spring pins must be installed outside the lamp shades of the No. 1 ultraviolet lamp and the No. 2 ultraviolet lamp, one The latch of the No. 1 UV lamp is installed outside the lamp shade. When the center line of the No. 1 UV lamp is perpendicular to the wall, the latch is inserted into the round hole reserved on the first joint, thereby achieving locking. If you want to restore free rotation, you must manually turn the plate to the left to force the latch to be pulled out of the round hole reserved on the first joint to unlock and rotate freely. The latch of the No. 2 UV lamp is also installed outside the lamp shade. When the center line of the No. 2 UV lamp is consistent with the center line of the No. 1 UV lamp, the latch passes through the reserved round hole of the rotating cylinder under the second joint and is inserted into the second joint. When in use, first manually move the No. 1 and No. 2 ultraviolet lamps to the center of the bed, and then press the switch button once to start the default one-hour timing. The ultraviolet lamp will start to glow 30 seconds after the person leaves the room and closes the bedroom door, and it will start to shake its head one minute after the glow. One minute before the set time, the shaking head stops when it reaches the lower position, and the ultraviolet lamp will also stop emitting light when the time is up. This is all controlled by a single-chip computer program.

[0008] A valve controller motor is installed below the first joint and above and below the second joint, respectively. The male thread at the lower end of the vertical column is changed to a cut-edge oblong with the same size as that on the ball valve of the electric ball valve. The bottom of the first joint is made into a male thread, and a connecting screw bowl is added. The connecting screw bowl is a bowl-shaped part with knurling on the outside and a female thread matching the male thread at the bottom of the first joint on the inside of the large end. A through hole is opened in the center of the bowl bottom, and a male thread matching the connecting screw sleeve is machined on the outside of the bowl bottom; a male thread is added to the top of the second joint, and a flange is added to the bottom; a flange is added to the top of the rotary cylinder under the second joint, and a male thread is added to the bottom; the upper and lower ends of the center rod of the second joint must be made into valves similar to those of the electric ball valve. The cut-edge oblong of the same size needs to be equipped with a connecting clamp. The connecting clamp is a circular ring with a "U"-shaped cross-section, which is sawn into two halves along the diameter direction, and a small ear with a hole is welded on both sides of each half. It is fixed into a whole again through two sets of bolts and nuts. The purpose of this is to allow the second joint and the rotating cylinder under the second joint to have relative rotation without being separated. When in use, just press the switch button, and the rest will be automatically completed by the device: the deployment of the No. 1 ultraviolet lamp and the No. 2 ultraviolet lamp takes 8 to 15 seconds, and the ultraviolet lamp tube will light up 30 seconds after the person leaves the bedroom.

[0034] A lower lift plate 34 is fixedly connected to the outside above the lower rotating cylinder 33 of the second joint. The size and specifications of this part are exactly the same as those of the upper lift plate 29. The connection method between this part and the second ultraviolet lamp 5 is also exactly the same as the connection method between the first ultraviolet lamp 3 and the second joint 4, which will not be repeated here.

[0035] The circuit principle of the utility model is shown in Fig.12 , its electrical connection is as follows: the power plug 56 is electrically connected to the power line 57, the power line 57 is electrically connected to the power supply board 58, the power supply board 58 is electrically connected to the computer board 59, the computer board 59 is electrically connected to the switch button 20, the computer board 59 is electrically connected to the indicator light 35, the computer board 59 is electrically connected to the infrared sensor 36, the computer board 59 is electrically connected to the control circuit 64, the control circuit 64 is electrically connected to the jack 60, the jack 60 is electrically connected to the plug 61, the plug 61 is electrically connected to the door magnetic switch reed switch 62, the door magnetic magnet 63 is used in conjunction with the door magnetic switch reed switch 62, the control circuit 64 is electrically connected to the first ultraviolet lamp ballast 65 and the second ultraviolet lamp ballast 66, and the first ultraviolet lamp ballast 65 and the second ultraviolet lamp ballast 66 are electrically connected to the two ultraviolet lamp tubes 26. All electrical components and circuit boards, except the power line 57, the power plug 56, the plug 61, the door magnetic switch reed switch 62, and the door magnetic magnet 63, are installed in the support 1.

[0036] The electrical working principle is: when the power plug 56 is inserted into the socket, the 220V mains electricity enters the power supply board 58 through the power cord 57. The power supply board 58 provides low-voltage direct current to the computer board 59, the indicator light 35, and the infrared sensor 36. At the same time, a fuse (not shown in the figure) is installed to prevent the circuit from short-circuiting and causing a fire, and it also serves as a path for alternating current. The computer board 59 is equipped with a microprocessor integrated block, which receives the signal instructions of the switch button 20 and the infrared sensor 36, and sends the calculation results to the control circuit 64. At the same time, the working state is indicated by the indicator light 35. The indicator light 35 is a three-primary color light-emitting diode, so one lamp can indicate multiple working states. The control circuit 64 is a switch, and one of the three options can be used: relay, bidirectional thyristor (thyristor), and IGBT. The input is provided by the computer board 59, and the signal output to the first ultraviolet lamp ballast 65 and the second ultraviolet lamp ballast 66 is the on and off of the mains. The ultraviolet lamp tube 26 is lit when the power is on, and the ultraviolet lamp tube 26 is off when the power is off.

[0037] The signal provided by the computer board 59 passes through the jack 60, which is a commercially available 3.5mm two-core jack, used in conjunction with the plug 61, which is a commercially available 3.5mm two-core plug, and its two cores are respectively connected (electrically connected) to the two ends of the door magnetic switch reed switch 62 through wires. The door magnetic switch reed switch 62 is installed above the bedroom door frame, and the door magnetic magnet 63 matched therewith is installed above the bedroom door. The jack 60 is installed at the bottom of the support housing 7. When the plug 61 is not inserted, the two pins of the jack 60 are connected together. After the plug 61 is inserted, the door magnetic switch reed switch 62 is connected in series between the two pins of the jack 60. Only when the door magnetic magnet 63 is close to the door magnetic switch reed switch 62, that is, when the bedroom door is completely closed, the two electrodes of the reed switch 62 are attracted together, the circuit is turned on, the control signal can enter the control circuit 64, and the two ultraviolet lamps can work. In other words, after the plug 61 is inserted, the bedroom door must be closed, and the ultraviolet lamp will light up. When the plug 61 is not inserted, the ultraviolet lamp is only controlled by the infrared sensor 36 and the switch button 20 and has nothing to do with the bedroom door.

[0038] When in use, first move the No. 1 ultraviolet lamp 3 and the No. 2 ultraviolet lamp 5 to the working position in the center of the bed 6, plug in the power plug 56, and the indicator light 35 is always green, indicating that the power is on and enters the standby state. At this time, just press the switch button 20, and the indicator light 35 will be short green for 0.5 seconds (off for 0.5 seconds), long white for 1.5 seconds (off for 0.5 seconds) in a cycle, indicating that the system default one-hour timing program is about to enter. When the person leaves the room, the indicator light 35 turns blue and flashes, on for 0.5 seconds and off for 0.5 seconds for a total of 30 times, then the indicator light 35 turns red and always lights up, and the two ultraviolet lamp tubes 26 light up together, and turn off after one hour, and the indicator light 35 is restored to the standby state of being always green. During this period, if the bedroom door is opened, the two ultraviolet lamp tubes 26 will turn off immediately, but will light up again when the door is closed. When the infrared sensor 36 senses that someone is in the bedroom, the two ultraviolet lamps 26 are immediately extinguished, but will not light up again after the person leaves. The indicator light 35 returns to the green standby state, and can only be delayed and lit up again by pressing the switch button 20 once.

[0039] If you want to increase the drying time, you can press and hold the switch button 20 for two seconds or longer and then release it. The indicator light 35 will turn yellow and the system will enter the timing adjustment state. At this time, as long as you press the switch button 20 once, the indicator light 35 will change from yellow and constant to short green light for 0.5 seconds and long white light for 1.5 seconds for one hour. Press the switch button 20 again, and the indicator light 35 will turn short cyan light for 0.5 seconds twice and long white light for 1.5 seconds for two hours. If you press the switch button 20 again, the indicator light 35 will turn short purple light for 0.5 seconds three times and long white light for 1.5 seconds for three hours. Press the switch button 20 again, and the indicator light 35 will turn short yellow light for 0.5 seconds four times and long white light for 1.5 seconds for four hours. If you press it again, the one-hour timing will be restored; if you press it again, the two-hour timing will be restored... and so on. If a person has been in the room, the indicator light 35 will flash in two colors in a cycle. When the person leaves, the indicator light 35 will immediately turn blue and flash for 30 seconds before turning red and lighting up steadily. The two ultraviolet lamps 26 will also light up simultaneously from the moment the indicator light 35 turns red and lighting up steadily.

[0040] Embodiment 2: Sliding solution. The above basic type is only suitable for double beds. For single beds, the bed head and one side are against the wall, and the bed center is only 0.5 meters away from one side wall. However, the length of one ultraviolet lamp tube 26 of the utility model is more than 0.9 meters, which makes it impossible to fold against the wall. Solution: A slide rail can be fixed horizontally on the wall 8 on the side of the bed head, and the support 1 can be installed on the slide rail. When not in use, the support 1 can be slid to the corner of the wall and then folded to solve the problem.

[0041] Embodiment 3: Shaking head solution. Since the ultraviolet lamp 26 is placed in the center of the bed 6 and is far away from both sides of the bed 6, a shaking head solution can be adopted to make the irradiation uniform. Figure 8 First, a key part is to be added, that is, the main support tube 46. The main support tube 46 is a metal cylinder, and the inner diameter is slidably matched with the main support 16. The main support tube 46 is fixedly connected (welded or riveted) to the support plate 14, and two rolling bearings can also be installed inside so that the rotation will be easier. An upper rocker arm 39 is sandwiched between the two nuts behind the main support 16. The upper rocker arm 39 is a metal plate with holes at both ends, one end is large and the other end is small. The hole at the large end is sleeved on the male thread at the tail end of the main support 16, and is clamped by two nuts to form a fixed connection. The small end is fixedly connected with an upper rod shaft 43a. The upper rod shaft 43a is a stepped circular shaft, and a connecting rod 42 is sleeved on it. The connecting rod 42 is a strip-shaped metal plate with round holes at both ends. The upper end round hole is sleeved on the upper rod shaft 43a of the upper rocker arm 39 for hinge connection, and the lower end round hole is sleeved on the lower rod shaft 43 of the lower rocker arm 44 for hinge connection. The small end of the upper rocker arm 39 is fixedly connected with a stop magnet 41, which cooperates with the stop reed switch 40 fixedly connected to the support reinforcement plate 11, so that the main support 16 can only stop when the ultraviolet lamp tube 26 is directly below it during the shaking process.

[0042] At the lower right of the support reinforcement plate 11, there is also a oscillating motor 45 fixedly connected. The oscillating motor 45 is a commercially available product, that is, the oscillating motor of an ordinary wall-mounted remote control fan. The output shaft of the motor is fixedly connected with a lower rocker arm 44. The lower rocker arm 44 is a plate-shaped metal part with round holes at both ends. The big head is fixedly connected (riveted) with a metal sleeve. The metal sleeve is drilled with holes along the diameter direction and tapped with female threads. A screw is screwed into the female thread. The screw is pushed into the small hole on the output shaft of the oscillating motor 45 to achieve a fixed connection. The small head of the lower rocker arm 44 is riveted with a lower rod shaft 43. The lower rod shaft 43 and the upper rod shaft 43a are the same large-head stepped cylindrical parts. The lower rod shaft 43 is movably sleeved with a connecting rod 42.

[0043] In order to prevent the first ultraviolet lamp 3 or the second ultraviolet lamp 5 from hanging down during the shaking process, thereby affecting the normal operation of the swing head, two spring latches must be installed outside the lamp shades 23 of the first ultraviolet lamp 3 and the second ultraviolet lamp 5 (the latches may not be present in the basic model without shaking head, but must be present in the swing head model). The structure of the spring latches is shown in FIG. Fig. 9The bolt 51 is placed in the spring bolt bracket 47. The bolt 51 is a stepped cylindrical metal part with a thin left side and a thick right side. The thick end is a round head or a pointed head. A part of the thickest part in the middle is cut off below to prevent it from rotating. A spring 50 is sleeved on the left side. A pick plate 49 is fixedly connected (riveted or welded) at the left end. The pick plate 49 is a strip-shaped metal plate with a round hole at the lower end. It is fixedly connected to the left end of the bolt 51 and has a bend at the upper end to facilitate finger movement. The spring 50 is an ordinary spiral spring wound with steel wire. The left side of the spring 50 is pressed against the folded part on the left side of the spring bolt bracket 47, and the right side of the spring 50 is pressed against the thickest step in the middle of the bolt 51. The spring bolt bracket 47 is a "U"-shaped part folded from a metal plate. There are round holes at both ends and both sides. The left hole is slidably matched with the thinner part on the left side of the bolt 51, and the right hole is slidably matched with the thicker part on the right side of the bolt 51; the holes on both sides are fixedly connected to the spring bolt support plate 48 through screws and nuts. The spring latch support plate 48 is a curved strip-shaped metal plate with the same curvature as the lamp shade 23 . The lower part of the upper end is fixedly connected to the top surface of the lamp shade through the lamp shade fixing screws 24 , and the lower end is fixedly connected to the spring latch bracket 47 .

[0044] The latch 51 of the first ultraviolet lamp 3 is installed outside the lamp shade 23. When the center line of the first ultraviolet lamp 3 is perpendicular to the wall 8, the latch 51 is inserted into the reserved circular hole on the first joint 2, thereby achieving locking. If you want to restore free rotation, you must manually turn the plate 49 to the left, forcing the latch 51 to overcome the elastic force of the spring 50 and pull it out of the reserved circular hole on the first joint 2 to unlock and rotate freely.

[0045] The latch 51 of the second ultraviolet lamp 5 is also installed outside the lamp shade 23. When the center line of the second ultraviolet lamp 5 is consistent with the center line of the first ultraviolet lamp 3, the latch 51 passes through the reserved round hole of the second joint lower rotating cylinder 33 and is inserted into the reserved round hole on the thinner cylinder at the lower end of the second joint 4, thereby achieving locking. If you want to restore free rotation, you must also manually turn the plate 49 to the left to pull the head of the latch 51 out of the reserved round hole on the thinner cylinder at the lower end of the second joint 4 to release the lock, so that the second ultraviolet lamp 5 can be folded to the wall 8.

[0046] When folded to the wall 8, a shallow hole can also be drilled at the corresponding position on the thinner cylinder at the lower end of the first joint 2 and the second joint 4. When folded into place, it has a self-locking effect. When unfolded for use, there is no need to pull the plate 49, and the lamp shade 23 can be directly pulled.

[0047] When in use, first manually move the No. 1 UV lamp 3 and the No. 2 UV lamp 5 to the center of the bed 6, and then press the switch button 20 once to start the default one-hour timing or select the timing duration (press for more than 2 seconds and release to select the timing duration, up to 4 hours). When the person leaves the room and closes the bedroom door, the UV lamp 26 will start to emit light 30 seconds later, and start shaking the head one minute after the light is emitted; when the head shakes to the right position one minute before the set time, the shaking action stops, and the UV lamp 26 stops emitting light when the time is up. All of these are controlled by a single-chip computer program.

[0048] After stopping use, if folding is needed, the corresponding pull plate 49 can be folded against the wall by hand.

[0049] Embodiment 4: Fully automatic solution. As long as a valve controller motor 54 (also known as an electric ball valve actuator, available on Taobao) is installed below the first joint 2 and above and below the second joint 4, full automation can be achieved. See the specific solution structure for details. Fig.10 , Fig.11 First, the vertical column 28 must be changed, the original male thread must be changed to a cut-edge oblong with the same size as the ball valve of the electric ball valve, and the bottom of the first joint 2 must be made into a male thread, and a key part must be added: a connecting screw bowl 52, which is a bowl-shaped part with knurling on the outside, a female thread that matches the male thread at the bottom of the first joint 2 on the inside of the large end, a through hole at the center of the bowl bottom, and a male thread that matches the connecting screw sleeve 53 on the outside of the bowl bottom. The connecting screw sleeve 53 is a part that comes with the valve controller motor 54, which is made by the valve manufacturer and used as a connector between the valve (ball valve) and the motor.

[0050] The valve controller motor 54 is divided into two categories: low-voltage DC motor and high-voltage AC motor. In terms of control method, there are two types: two-wire and three-wire. Low-voltage DC motors are all two-wire, which are turned on by forward power (small motor deceleration, the opening time is 8 to 15 seconds, and the power is cut off after turning on), and turned off by reverse power (power is cut off after closing). However, AC does not distinguish between positive and negative poles, and reversing is useless. The two-wire control method is: turn on by connecting the live wire, and turn off by disconnecting the live wire (using its own stored electrical energy). In addition to the live wire and the neutral wire, the three-wire also has a control wire. When in use, the live wire and the neutral wire are often connected to the circuit. The control wire is turned on when it is connected to the live wire, and the control wire is turned off when it is connected to the neutral wire. The utility model uses a low-voltage DC type, which is safe. Secondly, it already has a low-voltage DC power supply, and does not increase cost and complexity.

[0051] The modified structure of the second joint 4 is shown in Fig.11, there is no need to add a thin tube inside the second joint 4, but a male thread should be added to the top and a flange should be added to the bottom; the second joint lower rotary cylinder 33 is just the opposite, with a flange added to the top and a male thread added to the bottom. The second joint center rod 32 should be thickened, and both the upper and lower ends should be made into a cut-edge oblong with the same valve size as the electric ball valve, and the specific structure is exactly the same as the lower part of the first joint 2. The original second joint center rod 32, as a connecting piece, is now fully floating and has lost its connecting function, so another connecting piece is added: a connecting snap ring 55. The connecting snap ring 55 is a circular ring with a "U" shape in section, which is sawn into two halves along the diameter direction, and a small ear with a hole is welded on both sides of each half. It is fixed again into a whole through two sets of bolts and nuts. The purpose of this is to allow the second joint 4 and the second joint lower rotary cylinder 33 to have relative rotation without being separated. For lightness, one or two thrust bearings can be added inside.

[0052] Because the valve controller motor 54 can only rotate the output shaft 90 degrees, it is just right to use the first joint 2, and the direction from the center line of the bed 6 to the parallel direction of the wall 8 is exactly 90 degrees. However, it cannot be used on the second joint 4, because it needs to fold the No. 2 ultraviolet lamp 5 under the No. 1 ultraviolet lamp 3, and it needs to rotate 180 degrees. Therefore, two valve controller motors 54 must be used to work together to complete it.

[0053] When in use, just press the switch button 20, and the rest is automatically completed by the device. The first ultraviolet lamp 3 and the second ultraviolet lamp 5 take 8 to 15 seconds to unfold, and the ultraviolet lamp tube 26 emits light 30 seconds after the person leaves the bedroom. When the irradiation time is up, the first ultraviolet lamp 3 and the second ultraviolet lamp 5 automatically retract toward the wall 8.

[0054] Embodiment 5: Fully automatic shaking head solution. As long as the above two solutions are implemented at the same time, it is a fully automatic shaking head style, but please note that the spring latch does not need to be installed.

[0055] Embodiment 6: Networking solution: As long as a Wifi module is installed in the support 1 of the above embodiment 5, a wireless connection can be achieved through the router and the Internet at home, so that the quilt can be remotely controlled at home from thousands of miles away through a mobile phone.
