Description

Technical Field

[0001] This invention relates to the field of smart homes, specifically to a smart home windowsill. Background Technology

[0002] Smart home is a residential platform that integrates facilities related to home life using comprehensive wiring technology, network communication technology, security technology, automatic control technology, and audio-visual technology. It builds an efficient management system for residential facilities and daily household affairs, improves home security, convenience, comfort, and aesthetics, and achieves an environmentally friendly and energy-saving living environment.

[0003] Different people often have their own different comfort spaces, and everyone's comfort space environment settings are different. Currently, existing home windowsills are mostly shaded by curtains, blinds, and other forms of blocking light. However, the above-mentioned light-blocking methods are difficult to achieve sensitive gradient adjustment in environments with direct sunlight. That is, it is difficult to choose a suitable light intensity in light and darkness, so there is still room for improvement in people's satisfaction.

[0004] Therefore, a smart home windowsill is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a smart home windowsill to solve the problem mentioned in the background art that existing home windowsills mostly use curtains, blinds and other forms of shading to block light. However, the above-mentioned light-blocking methods are difficult to achieve sensitive gradient adjustment in environments with direct sunlight. That is, it is difficult to choose a suitable light intensity in light and darkness, so there is still room for improvement in people's satisfaction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smart home windowsill, including a light-blocking mechanism, the light-blocking mechanism including a first light-blocking member and a second light-blocking member, the inner sides of the first light-blocking member and the second light-blocking member are provided with a plurality of evenly distributed hollow spaces, the first light-blocking member and the second light-blocking member are slidably disposed, the hollow spaces on the first light-blocking member and the hollow spaces on the second light-blocking member can overlap or be staggered, the first light-blocking member and the second light-blocking member are both made of transparent material;

[0007] The inner sides of both the first and second light-shielding components are fixedly provided with circulation pipes and housings. The housings have inlets and outlets at both ends, which are connected to the two ends of the circulation pipes. The circulation pipes are arranged in a curved and extended shape. Both the circulation pipes and the housings are filled with antifreeze. Light-shielding factors are provided inside the circulation pipes and the housings. Light blocking is achieved by circulating the light-shielding factors within the circulation pipes and the housings.

[0008] The light-blocking structure in this invention can be placed on the window. This invention can achieve indoor ventilation while blocking light, and can also adjust the light-blocking intensity. The voice recognition device, light sensor and central controller in this invention are used for voice recognition, automatic light sensing and control. They are existing technologies and will not be described in detail here.

[0009] When ventilation is performed, the first motor in this invention is started. The rotation of the first motor drives the rotation of the screw, which in turn drives the movement of the slider. The movement of the slider allows the second light-shielding member to move. When the hollow space in the second light-shielding member overlaps with the hollow space on the first light-shielding member, indoor ventilation is achieved.

[0010] In the initial state of this invention, the first filter completely blocks the inside of the housing, and the light-blocking factor is located on the side near the return water inlet. When the light is blocked, the slotted space in the second light-blocking component is offset from the slotted space on the first light-blocking component, so that the first filter opens the inside of the housing. The water pump works, and the water in the housing enters the inside of the circulation pipe along the inlet, and then flows back to the inside of the housing through the return water inlet to achieve circulation. During the circulation process, the light-blocking factor on the inside of the housing flows with the water flow in the inside of the circulation pipe, and the light-blocking effect is achieved through the light-blocking factor on the inside of the circulation pipe.

[0011] Because different light-shielding effects are required in different scenarios, this invention can adjust the light-shielding effect of the light-shielding factor. The light-shielding effect of the light-shielding structure is controlled by controlling the amount of light-shielding factor in the water flow. The control method is as follows: the second motor is started, the rotation of the second motor drives the rotation of the worm gear, the rotation of the worm gear drives the rotation of the worm wheel, and the rotation of the worm wheel drives the rotation of the second filter screen. When the second filter screen rotates downward, the angle formed between the second filter screen and the inner side of the shell gradually decreases and becomes an acute angle. Some of the light-shielding factor will be intercepted in the semi-enclosed space formed at the acute angle, which reduces the amount of light-shielding factor participating in the circulation pipe, reduces the density of light-shielding factor in the circulation pipe, and weakens the light-shielding ability.

[0012] When the second filter rotates upward, the angle formed between the second filter and the inner side of the shell gradually increases to an obtuse angle. More light-blocking factors can flow into the circulation pipe with the water flow. When the angle of the obtuse angle is larger, the number of light-blocking factors will be greater, the density of light-blocking factors in the circulation pipe will decrease, and the light-blocking ability will be weakened, thereby achieving the effect of adjusting the light-blocking ability.

[0013] When light protection is not required, the first filter can be controlled to completely block the housing. The light-blocking factors in the circulation pipe can be intercepted by the first filter on one side of the housing, eliminating the light-blocking factors flowing in the circulation pipe and achieving a light-transmitting effect.

[0014] As an optional solution for the smart home windowsill described in this invention, the inner side of the housing is provided with a water pump, a second filter, and a first filter in sequence from the water inlet to the water outlet. The water pump is fixedly installed on the inner side of the housing. The first filter can completely block the inner side of the housing. The second filter forms an angle with the inner side of the housing. By changing the size of the angle, the amount of light-blocking factor involved can be controlled. The second filter can partially block the inner side of the housing.

[0015] As an optional solution for a smart home windowsill according to the present invention, wherein: the density of the light-blocking factor is the same as the density of the antifreeze, the light-blocking factor is black particles, the diameter of the light-blocking factor is 0.2mm-0.8mm, and the water pump is a plunger pump.

[0016] Under the above settings, the density of the light-shielding factor in this invention is the same as the density of the antifreeze, so that the light-shielding factor can be suspended in the antifreeze and flow with the flow of the antifreeze. The diameter of the light-shielding factor is 0.2mm-0.8mm. This setting is used to prevent the light-shielding factor from being too large and affecting the normal use or life of the water pump. The light-shielding factor is made of black particles to prevent light from being reflected behind the light-shielding factor.

[0017] As an optional solution for the smart home windowsill described in this invention, the outer side of the housing is fixedly provided with a first drive housing and a second drive housing, the inner side of the first drive housing is fixedly provided with an electric push rod, the output end of the electric push rod is fixedly connected with a rack, the first drive housing is also provided with a gear, the center of the gear is fixedly connected to the rotating shaft in the first filter, the gear and the rack mesh, and the extension stroke of the electric push rod is one-quarter of the circumference of the gear.

[0018] When the electric push rod is activated, the movable end of the electric push rod moves downward, driving the rack to move. The rack's movement drives the gear to rotate, causing the first filter screen to rotate synchronously for angle adjustment. When the first filter screen opens the housing, the light-blocking factor can flow along the water flow inside the circulation pipe.

[0019] Under the above configuration, the extension stroke of the electric push rod in this invention is one-quarter of the circumference of the gear. This configuration enables the first filter to rotate 90° after each stroke of the electric push rod, thereby opening or closing the first filter inside the housing. When the first filter opens the housing, the light-blocking factor can flow inside the housing and the circulation pipe.

[0020] As an optional solution for the smart home windowsill described in this invention, a second motor is fixedly installed on the inner side of the second drive housing, a worm gear is fixedly connected to the output end of the second motor, a connecting plate is fixedly installed on the lower side of the second drive housing, the upper side of the connecting plate is rotatably connected to the bottom end of the worm gear, a worm wheel is also installed inside the second drive housing, the center of the worm wheel is fixedly connected to the rotating shaft of the second filter screen, and the worm gear meshes with the worm wheel.

[0021] As an optional solution for a smart home windowsill according to the present invention, the second filter includes an inner layer and an outer layer, the outer side of the inner layer is slidably connected to the inner side of the outer layer, a spring is fixedly connected between the top of the outer side of the inner layer and the bottom of the inner side of the outer layer, and an inclined portion is provided at the bottom of the outer layer.

[0022] With the above configuration, the outer side of the inner layer and the inner side of the outer layer are slidably connected, which can play a role in distance compensation. When the inner and outer layers rotate and approach the inner wall of the shell, the inner layer will touch the inner wall of the shell and retract to the inner side of the outer layer. When the inner and outer layers rotate and move away from the inner wall of the shell, the inner layer will slide to the outer side of the outer layer under the action of the spring. The inclined part is provided to reduce the gaps that appear at the connection between the inner and outer layers and prevent the light-blocking factor from getting stuck here.

[0023] As an optional solution for a smart home windowsill according to the present invention, the first light-shielding member has a groove at its top end, a screw is rotatably arranged on the inner side of the groove, a slider is spirally arranged on the outer side of the screw, one side of the slider is fixedly connected to the second light-shielding member, a first motor is fixedly arranged on the inner side of the first light-shielding member, and the output end of the first motor is fixedly connected to one end of the screw.

[0024] As an optional solution for the smart home windowsill described in this invention, an expansion ball is provided on the upper side of the housing, and the inner side of the expansion ball is connected to the inner side of the housing.

[0025] Under the above configuration, because the antifreeze in the shell and circulation pipe has a certain coefficient of thermal expansion, the expansion ball can play a role in spatial compensation when the temperature is too high or too low, preventing stress from occurring in the shell and circulation pipe.

[0026] As an optional solution for the smart home windowsill described in this invention, the first light-shielding member is further equipped with a voice recognizer, a light sensor, and a central controller. The voice recognizer is used by the user to control the degree of light blocking according to voice commands, and the light sensor is used to detect the current ambient light inside the room.

[0027] A method for using a smart home windowsill, the steps of which are as follows:

[0028] Step 1: Start the first motor to make the slotted space on the first light-shielding component overlap with the slotted space on the second light-shielding component to achieve ventilation;

[0029] Step 2: Start the water pump and electric actuator to open the housing of the first filter screen, allowing the light-blocking agent to participate in the circulation of the pipe;

[0030] Step 3: Start the second motor, change the angle of the second filter, and adjust the intensity of light blocking.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. In this smart home window sill, when ventilation is required, the first motor of the invention is activated. The rotation of the first motor drives the rotation of the screw, which in turn drives the movement of the slider. The movement of the slider allows the second light-shielding member to move. When the perforated space in the second light-shielding member overlaps with the perforated space on the first light-shielding member, indoor ventilation is achieved.

[0033] 2. In this smart home window sill, when light is blocked, the perforated space in the second light-blocking component is offset from the perforated space on the first light-blocking component, causing the first filter to open the inside of the housing. The water pump works, and the water inside the housing enters the inside of the circulation pipe through the inlet, and then flows back to the inside of the housing through the return outlet to achieve circulation. During the circulation process, the light-blocking factor on the inside of the housing flows with the water flow in the circulation pipe, and the light-blocking effect is achieved through the light-blocking factor on the inside of the circulation pipe.

[0034] 3. This smart home windowsill, because the required light-blocking effect varies in different scenarios, can adjust the light-blocking effect of the light-blocking factor. The light-blocking effect of the light-blocking structure is controlled by controlling the amount of light-blocking factor in the water flow. The control method is as follows: the second motor is started, the rotation of the second motor drives the rotation of the worm gear, the rotation of the worm gear drives the rotation of the worm wheel, and the rotation of the worm wheel drives the rotation of the second filter screen. When the second filter screen rotates downward, the angle formed between the second filter screen and the inner side of the shell gradually decreases and becomes an acute angle. Some of the light-blocking factor will be intercepted in the semi-enclosed space formed at the acute angle, reducing the amount of light-blocking factor participating in the circulation pipe, reducing the density of light-blocking factor in the circulation pipe, and weakening the light-blocking ability.

[0035] 4. In this smart home windowsill, when the second filter rotates upward, the angle formed between the second filter and the inner side of the shell gradually increases to an obtuse angle. More light-blocking factors can flow into the circulation pipe with the water flow. When the angle of the obtuse angle is larger, the number of light-blocking factors will be greater, the density of light-blocking factors in the circulation pipe will decrease, and the light-blocking ability will be weakened, thereby achieving the effect of adjusting the light-blocking ability.

[0036] 5. This smart home windowsill, when light blocking is not required, can control the first filter to completely block the shell, and the light-blocking factors in the circulation pipe can be intercepted by the first filter on one side of the shell, eliminating the light-blocking factors flowing in the circulation pipe and achieving a light transmission effect.

[0037] 6. In this smart home windowsill, the density of the light-blocking factor is the same as that of the antifreeze, allowing the light-blocking factor to be suspended in the antifreeze and flow with the flow of the antifreeze. The diameter of the light-blocking factor is 0.2mm-0.8mm. This setting is used to prevent the light-blocking factor from being too large and affecting the normal use or lifespan of the water pump. The light-blocking factor is made of black particles to prevent light from being reflected behind the light-blocking factor.

[0038] 7. In this smart home windowsill, the outer side of the inner layer and the inner side of the outer layer are slidably connected, which can play a role in distance compensation. When the inner and outer layers rotate and approach the inner wall of the shell, the inner layer will touch the inner wall of the shell and retract to the inner side of the outer layer. When the inner and outer layers rotate and move away from the inner wall of the shell, the inner layer will slide to the outer side of the outer layer under the action of the spring. The inclined part is designed to reduce the gaps that appear at the connection between the inner and outer layers and prevent the light-blocking factor from getting stuck here.

[0039] 8. This smart home window sill, because the antifreeze in the shell and circulation pipe has a certain coefficient of thermal expansion, can play a role in space compensation when the temperature is too high or too low, preventing stress in the shell and circulation pipe.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1, please refer to Figure 1 and 2 This invention provides a technical solution: a smart home windowsill, including a light-blocking mechanism, comprising a first light-blocking component 1 and a second light-blocking component 2. The inner sides of both the first and second light-blocking components 1 and 2 are provided with a plurality of evenly distributed perforated spaces 7. The first and second light-blocking components 1 and 2 are slidably disposed, and the perforated spaces 7 on the first and second light-blocking components 1 and 2 can overlap or be staggered. Both the first and second light-blocking components 1 and 2 are made of transparent material. The light-blocking structure of this invention can be placed on the window frame. This invention can achieve both light blocking and indoor ventilation, and can also adjust the light-blocking intensity.

[0054] When ventilation is performed, the first motor 5 in this invention is started. The rotation of the first motor 5 drives the rotation of the screw 3. The rotation of the screw 3 drives the movement of the slider 4. The movement of the slider 4 enables the second light-shielding member 2 to move. When the hollow space 7 in the second light-shielding member 2 overlaps with the hollow space 7 on the first light-shielding member 1, indoor ventilation is achieved.

[0055] Specifically, the top of the first light-shielding member 1 is provided with a groove 3, a screw 6 is rotatably provided on the inner side of the groove 3, a slider 4 is spirally provided on the outer side of the screw 6, one side of the slider 4 is fixedly connected to the second light-shielding member 2, a first motor 5 is fixedly provided on the inner side of the first light-shielding member 1, and the output end of the first motor 5 is fixedly connected to one end of the screw 6.

[0056] Example 2 is a further improvement upon Example 1. Please refer to [link / reference]. Figure 1-11 The inner sides of the first light-shielding member 1 and the second light-shielding member 2 are both fixedly provided with a circulation pipe 8 and a housing 15. The housing 15 has an inlet 11 and an outlet 12 at both ends. The inlet 11 and the outlet 12 are respectively connected to the two ends of the circulation pipe 8. The circulation pipe 8 is arranged in a curved extension shape. The interior of the circulation pipe 8 and the housing 15 is filled with antifreeze. The interior of the circulation pipe 8 and the housing 15 is provided with a light-shielding factor 13. Light blocking is achieved by the circulation flow of the light-shielding factor 13 in the circulation pipe 8 and the housing 15.

[0057] In the initial state of the present invention, the first filter screen 17 completely blocks the inside of the housing 15, and the light-blocking factor 13 is located on the side near the return water inlet 12. When the light is blocked, the slotted space 7 in the second light-blocking member 2 is offset from the slotted space 7 on the first light-blocking member 1, so that the first filter screen 17 opens the inside of the housing 15. The water pump 14 works, and the water in the housing 15 enters the inside of the circulation pipe 8 along the water inlet 11, and then flows back to the inside of the housing 15 through the return water inlet 12 to achieve circulation. During the circulation process, the light-blocking factor 13 on the inside of the housing 15 flows with the water flow in the inside of the circulation pipe 8, and the light-blocking effect is achieved by the light-blocking factor 13 on the inside of the circulation pipe 8.

[0058] Example 3 is a further improvement on Example 2. Please refer to Example 2. Figure 1-11 The inner side of the housing 15 is provided with a water pump 14, a second filter screen 16 and a first filter screen 17 in sequence from the water inlet 11 to the water outlet 12. The water pump 14 is fixedly installed inside the housing 15. The first filter screen 17 can completely block the inner side of the housing 15. The second filter screen 16 forms an angle 25 with the inner side of the housing 15. The amount of participation of the shading factor 13 can be controlled by changing the size of the angle 25. The second filter screen 16 can partially block the inner side of the housing 15.

[0059] Because different light-shielding effects are required in different scenarios, this invention can adjust the light-shielding effect of the light-shielding factor 13. The light-shielding effect of the light-shielding structure is controlled by controlling the amount of light-shielding factor 13 in the water flow. The control method is as follows: the second motor 18 is started, the rotation of the second motor 18 drives the rotation of the worm gear 19, the rotation of the worm gear 19 drives the rotation of the worm wheel 20, and the rotation of the worm wheel 20 drives the rotation of the second filter screen 16. When the second filter screen 16 rotates downward, the angle 25 formed between the second filter screen 16 and the inner side of the shell 15 gradually decreases and becomes an acute angle. A portion of the light-shielding factor 13 will be intercepted in the semi-enclosed space formed at the acute angle, reducing the amount of light-shielding factor 13 participating in the circulation pipe 8. The density of the light-shielding factor 13 in the circulation pipe 8 decreases, thus weakening the light-shielding ability.

[0060] When the second filter 16 rotates upward, the angle 25 formed between the second filter 16 and the inner side of the housing 15 gradually increases to an obtuse angle, and more light-blocking factors 13 can flow into the circulation pipe 8 with the water flow. When the angle of the obtuse angle is larger, the number of light-blocking factors 13 will be greater, and the density of light-blocking factors 13 in the circulation pipe 8 will decrease, making the light-blocking ability weaker, thereby achieving the effect of adjusting the light-blocking ability.

[0061] When light protection is not required, the first filter 17 can be controlled to completely block the housing 15. The light-blocking factor 13 in the circulation pipe 8 can be intercepted by the first filter 17 on one side of the housing 15, eliminating the light-blocking factor 13 flowing in the circulation pipe 8 and achieving a light transmission effect.

[0062] Specifically, the density of the aforementioned light-shielding factor 13 is the same as that of the antifreeze, the aforementioned light-shielding factor 13 is a black particle, the aforementioned light-shielding factor 13 has a diameter of 0.2mm-0.8mm, and the aforementioned water pump 14 is a plunger pump.

[0063] Under the above configuration, the density of the light-shielding factor 13 in this invention is the same as the density of the antifreeze, so that the light-shielding factor 13 can be suspended in the antifreeze and flow with the flow of the antifreeze. The diameter of the light-shielding factor 13 is 0.2mm-0.8mm. This configuration is used to prevent the light-shielding factor 13 from being too large and affecting the normal use or lifespan of the water pump 14. The light-shielding factor 13 is a black particle that can prevent light from being reflected after hitting the light-shielding factor 13.

[0064] Specifically, a first drive housing 9 and a second drive housing 10 are fixedly disposed on the outer side of the aforementioned housing 15. An electric push rod 22 is fixedly disposed on the inner side of the aforementioned first drive housing 9. A rack 24 is fixedly connected to the output end of the aforementioned electric push rod 22. A gear 23 is also disposed inside the aforementioned first drive housing 9. The center of the aforementioned gear 23 is fixedly connected to the rotating shaft in the first filter screen 17. The aforementioned gear 23 and rack 24 mesh with each other. The extension and retraction stroke of the aforementioned electric push rod 22 is one-quarter of the circumference of the gear 23.

[0065] When the electric push rod 22 is activated, the movable end of the electric push rod 22 moves downward, driving the rack 24 to move. The movement of the rack 24 drives the gear 23 to rotate, causing the first filter screen 17 to rotate synchronously to adjust the angle. When the first filter screen 17 opens the housing 15, the light-blocking factor 13 can flow along the water flow inside the circulation pipe 8.

[0066] Under the above configuration, the extension stroke of the electric push rod 22 in this invention is one-quarter of the circumference of the gear 23. This configuration enables the first filter 17 to rotate 90° after each stroke of the electric push rod 22, thereby opening or closing the first filter 17 within the housing 15. When the first filter 17 opens the housing 15, the light-blocking factor 13 can flow within the housing 15 and the circulation pipe 8.

[0067] Specifically, a second motor 18 is fixedly installed inside the second drive housing 10, and a worm gear 19 is fixedly connected to the output end of the second motor 18. A connecting plate 21 is fixedly installed on the lower side of the second drive housing 10, and the upper side of the connecting plate 21 is rotatably connected to the bottom end of the worm gear 19. A worm wheel 20 is also installed inside the second drive housing 10, and the center of the worm wheel 20 is fixedly connected to the rotating shaft of the second filter screen 16. The worm gear 19 meshes with the worm wheel 20.

[0068] Specifically, the second filter 16 includes an inner layer 16b and an outer layer 16a. The outer side of the inner layer 16b is slidably connected to the inner side of the outer layer 16a. A spring 16c is fixedly connected between the top outer side of the inner layer 16b and the bottom inner side of the outer layer 16a. An inclined portion 29 is provided at the bottom of the outer layer 16a.

[0069] Under the above configuration, the outer side of the inner layer 16b and the inner side of the outer layer 16a are slidably connected, which can play a role in distance compensation. When the inner layer 16b and the outer layer 16a rotate closer to the inner wall of the housing 15, the inner layer 16b will touch the inner wall of the housing 15 and retract to the inner side of the outer layer 16a. When the inner layer 16b and the outer layer 16a rotate away from the inner wall of the housing 15, the inner layer 16b will slide to the outer side of the outer layer 16a under the action of the spring 16c. The inclined part 29 is provided to reduce the gaps that appear at the connection between the inner layer 16b and the outer layer 16a and prevent the light-blocking factor 13 from getting stuck here.

[0070] Specifically, an expansion ball 26 is provided on the upper side of the housing 15, and the inner side of the expansion ball 26 is connected to the inner side of the housing 15.

[0071] Example 4 is a further improvement on Example 2. Please refer to Example 2. Figure 1-11Under the above configuration, since the antifreeze in the housing 15 and the circulation pipe 8 has a certain coefficient of thermal expansion, the expansion ball 26 can play a role in space compensation when the temperature is too high or too low, preventing stress from occurring in the housing 15 and the circulation pipe 8.

[0072] Specifically, the first light-shielding component 1 is also equipped with a voice recognizer 27, a light sensor 28, and a central controller 30. The voice recognizer 27, light sensor 28, and central controller 30 in this invention are used for voice recognition, automatic light sensing, and control, and are existing technologies, so they will not be elaborated further here.

[0073] This invention also discloses a method for using a smart home windowsill, the steps of which are as follows:

[0074] Step 1: Start the first motor 5 so that the hollow space 7 on the first light-shielding member 1 overlaps with the hollow space 7 on the second light-shielding member 2 to achieve ventilation;

[0075] Step 2: Start the water pump 14 and the electric push rod 22 to open the housing 15 with the first filter screen 17, so that the light-blocking factor 13 can participate in the circulation of the circulation pipe 8;
