Technical Field

[0001] The present invention relates to the technical field of intelligent doors and windows, and specifically to an intelligent door and window that can open and close automatically at a fixed time. Background Technique

[0002] With the development of intelligent technology, the use of intelligent doors and windows is becoming more and more widespread. In the weather with large temperature differences between morning and evening, most people will choose to open the doors and windows for ventilation and cooling when sleeping indoors. And during the late night period, they will control the doors and windows to close automatically to avoid getting cold while sleeping. By starting and closing the doors and windows at a fixed time, it can avoid the trouble of getting up in the middle of the night to close the windows for indoor people, and has good application prospects in practical applications. However, the existing intelligent doors and windows have the following problems:

[0003] The use of intelligent doors and windows mostly involves some electronic devices that need to be powered. However, during daily life, power outages may occur. For existing intelligent doors and windows, it is not convenient to switch between manual and automatic opening and closing. Although occasional failure to close automatically at night will not have a great impact, during daily use, power outages will affect the use of indoor ventilation equipment. If the doors and windows cannot be opened manually, it will cause the indoor environment to be stuffy and reduce comfort. At this time, it is very necessary to be able to open the doors and windows manually. At the same time, as an important means to isolate external dust, after long-term use, a large amount of dust will accumulate on the outside of the window glass. If not cleaned in time, it will affect the light transmittance. For existing intelligent doors and windows, it is not convenient to clean the external glass. Cleaning by climbing the window manually is dangerous and the cleaning effect is not good.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original intelligent doors and windows. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent door and window that can open and close automatically at a fixed time, so as to solve the problems in the above-mentioned background technique that the existing intelligent doors and windows are not convenient to switch between manual and automatic opening and closing, and at the same time not convenient to clean the external glass.

The positioning rods are installed in the positioning grooves in a limited sliding manner, and the positioning grooves are formed at the outer side positions on the sides of the window sash. Inside the cleaning seat, a water tank, a water guiding roller and a cleaning roller are arranged from top to bottom. The water tank is embedded in the cleaning seat. The water guiding roller is embedded and fitted and installed in the internal cavity of the cleaning seat in a movable manner, and the cleaning roller is rotatably installed inside the cleaning roller. A gear is connected to the end of the water guiding roller, and a tooth block is engaged with the side of the gear. The tooth blocks are evenly distributed at the outer side positions on the sides of the window sash. Water guiding holes are formed on the outer side of the water guiding roller. A water passing hole is formed at the position between the bottom of the water tank and the water guiding roller, and a water passing hole is also formed at the position between the water guiding roller and the inner side wall of the window sash. The top of the cleaning seat is connected with a limiting head through a high-strength nylon thread. The bottom of the limiting head is installed in a limited manner through two L-shaped rods made of rubber and fixed on the window sash. The top of the limiting head is embedded and placed in the outer cavity of the top cross beam of the window sash.

[0010] Preferably, a telescopic groove is formed at the top edge of the outer side of the window frame, and an installation rod is connected in the telescopic groove through an elastic telescopic rod. A pressure sensor is installed at the bottom of the telescopic groove, and the pressure sensor is located below the installation rod. A water collecting hopper is fixed at the top of the outer side of the installation rod, and a water leakage hole is formed through the outer side of the installation rod. A plugging block is connected in the water leakage hole through a return spring. The water leakage hole is located at the bottom of the water collecting hopper. At the same time, the bottom of the water collecting hopper is provided with a hollow structure. A top rod is arranged below the plugging block, and the top rod is fixed on the outer side of the window frame in an "L" shape to collect rainwater and cooperate with the gravity sensor and the controller to control the automatic closing of the window.

[0011] Preferably, the adjusting roller and the guide rod share the same central axis, and the adjusting roller and the guide rod do not contact each other. The motor drives the guide rod to rotate, and the adjusting roller can be driven to rotate through the positioning sleeve.

[0012] Preferably, the adjusting rod is slidably installed in the adjusting groove in a fitting manner, and the adjusting groove is distributed in a spiral structure on the adjusting roller. When the adjusting roller rotates, it drives the adjusting rod to move, and then the automatic opening and closing of the window sash is realized through the pushing rod.

[0013] Preferably, a pulling rope is fixed on the outer side of the movable sleeve, and one end of the pulling rope penetrates through the interior of the window frame and is connected to a limiting roller. The limiting roller is elastically slidably installed in the outer cavity of the top cross beam of the window sash through a limiting spring. And the pulling rope moves in the window frame through a guide shaft. One end of the limiting roller is located in the limiting groove, and the limiting groove is opened at the side position of the limiting head. When the movable sleeve is moved, the limiting roller is driven to move through the pulling rope. Through the cooperation and separation of the limiting roller and the limiting groove, the switching between the cleaning state and the non-cleaning state is realized.

[0014] Preferably, the docking teeth are evenly angularly distributed on the guide rod, the adjusting roller and the positioning sleeve. The docking teeth on the positioning sleeve are staggeredly distributed with the docking teeth on the guide rod and the adjusting roller. And both sides of the edge end of the docking tooth are designed in an inclined structure. When the movable sleeve and the positioning sleeve are moved, the docking teeth can be used to realize the clamping state of the positioning sleeve with the guide rod and the adjusting roller, which is convenient for the guide rod to rotate and can drive the adjusting roller to rotate. At the same time, the movable sleeve and the positioning sleeve are separated from the adjusting roller, so that the adjusting roller can rotate by itself, which is convenient for manually opening and closing the window sash.

[0015] Preferably, the water guide holes are evenly angularly arrayed on the outer side of the water guide roller, and the distribution positions of the water guide holes correspond to those of the water through holes.

And the diameter of the top of the plugging block is smaller than the width above the water leakage hole. When the gravity of the water in the water collecting hopper increases, it drives the water collecting hopper and the mounting rod to move downward and contact the pressure sensor to realize rainwater induction. At the same time, when the plugging block reaches the top rod, it is jacked up, so that water can flow out of the water leakage hole, which is convenient for the reset of the water collecting hopper and the next use.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention is provided with an automatic and manual opening / closing switching mechanism. When the positioning sleeve is located between the adjusting roller and the guide rod, by using the docking teeth, the guide rod can drive the adjusting roller to rotate through the positioning sleeve. Furthermore, when the motor rotates forward and backward, the guide rod can drive the adjusting roller to rotate, and then cooperate with the adjusting groove, the adjusting rod and the pushing rod to drive the window sash to rotate, realizing automatic opening and closing. In case of a power outage, the cross bar can drive the movable sleeve and the positioning sleeve to move towards the guide rod, so that the positioning sleeve is separated from the adjusting roller. At this time, manually pull the window sash, and drive the adjusting roller to rotate through the pushing rod, the adjusting rod and the adjusting groove. The adjusting roller rotates independently and is not affected by the motor, which is convenient for manually operating the window sash. Through the manual and automatic switching, the need for ventilation when the room is stuffy during a power outage can be effectively solved. At the same time, the switching operation is simple, only the cross bar needs to be moved;

[0019] 2. The present invention is provided with a glass external cleaning mechanism. When manually opening and closing the window sash, switch by moving the cross bar to the left. At this time, the movement of the movable sleeve makes the stretching in a relaxed state. Under the action of the limit spring, the limit roller is inserted into the limit groove to limit the position of the limit head. At this time, when the window sash is opened again, the cleaning seat can be pulled up by the high-strength nylon thread, and the water guide roller is driven to rotate through the tooth block and the gear. Cooperating with the water guide hole and the water passing hole, the water in the water tank can be conveyed to the positions of the glass and the cleaning roller. As the window sash is repeatedly opened and closed manually, driving the up and down movement of the cleaning seat, the stubborn dirt on the external glass of the window sash can be efficiently cleaned, and the operation is simple. During the automatic opening and closing stage of the window sash, the movable sleeve limited by damping can make the limit roller separated from the limit groove through the pull rope. At this time, the movement of the window sash can drive the limit head to move together, and the cleaning seat maintains its original position and will not perform cleaning activities, saving water and reducing the motor loss at the same time. The automatic and manual switching of the window sash can be accompanied by the switching of the cleaning process, with high independent selectivity and at the same time affecting the automatic opening and closing of the window sash;

[0020] 3. The present invention is provided with a rainwater sensing mechanism. When the window sash encounters rainy weather after being opened, the rainwater accumulates in the water collecting hopper, causing the water collecting hopper to move downward under gravity, so that the mounting rod contacts the pressure sensor, which is convenient to cooperate with the single-chip microcomputer in the controller to control the operation of the motor and automatically close the window sash in time. The setting of the water collecting hopper, due to its small volume and capacity, will only accumulate enough rainwater after a large amount of rainfall or a long duration of rain. Therefore, in the early stage of light rain, the window sash will not be automatically closed. A large amount of rain is likely to cause rainwater to enter the room, and a long duration of light rain will be accompanied by a drop in temperature. It is more appropriate to close the window sash at this stage. Description of the Drawings

[0038] Example 3

[0039] See also Figure 1 and Figure 10, a telescopic groove 26 is formed at the top edge of the outer side of the window frame 1, and an installation rod 28 is connected in the telescopic groove 26 through an elastic telescopic rod 27. A pressure sensor 261 is installed at the bottom of the telescopic groove 26, and the pressure sensor 261 is located below the installation rod 28. A water collecting hopper 29 is fixed at the top of the outer side of the installation rod 28, and a water leakage hole 30 is formed through the outer side of the installation rod 28. A plugging block 32 is connected in the water leakage hole 30 through a return spring 31. The water leakage hole 30 is located at the bottom of the water collecting hopper 29. At the same time, the bottom of the water collecting hopper 29 is provided with a hollow structure. A top rod 33 is arranged below the plugging block 32, and the top rod 33 is fixedly arranged on the outer side of the window frame 1 in an "L" shape. The plugging block 32 elastically slides in the water leakage hole 30 through the return spring 31. The bottom of the plugging block 32 is designed as an isosceles trapezoid structure and is in concave-convex fit with the inner wall of the water leakage hole 30. The diameter of the top of the plugging block 32 is smaller than the width above the water leakage hole 30. In rainy weather, the water collecting hopper 29 collects rainwater. When the rainfall is large, the gravity of the water collecting hopper 29 is large, so that the water collecting hopper 29 and the installation rod 28 move downward and contact the pressure sensor 261, which can cooperate with the controller 3 to control the operation of the motor 4 to realize the automatic closing of the window sash 2.

[0040] Working principle: When using the intelligent door and window with timed autonomous opening and closing, such as Figures 1-10In it, first, the timing forward and reverse rotation of the motor 4 can be adjusted through the panel and buttons on the controller 3. The controller 3 includes control components such as a single-chip microcomputer and a timer. The motor 4 starts to drive the guide rod 12 to rotate, drives the positioning sleeve 9 to rotate in the movable sleeve 10 through the docking teeth 13, the positioning sleeve 9 drives the adjusting roller 5 to rotate through the docking teeth 13, drives the adjusting rod 7 to move through the adjusting groove 6, and the adjusting rod 7 can drive the window sash 2 to rotate in the window frame 1 through the movement and rotation of the push rod 8. The opening and closing of the window frame 1 are driven by the forward and reverse rotation of the motor 4. At the same time, when the window sash 2 is opened and closed by electric control, at this time, the limit roller 102 and the limit groove 104 are in a separated state, and the window sash 2 can drive the limit head 25 to move together. At this time, the cleaning seat 14 is at the lowest position and will not rise. When a power outage occurs and the window sash 2 needs to be opened and closed, the cross bar 11 can be manually pulled. The positioning sleeve 9 is driven to move leftward through the cross bar 11 and the movable sleeve 10, so that the positioning sleeve 9 is disengaged from the adjusting roller 5. At this time, the motor 4 is no longer linked with the adjusting roller 5, and the window sash 2 can be opened and closed by pulling the handle conventionally arranged on the window sash 2. The manual opening and closing of the window sash 2 will drive the adjusting roller 5 to rotate through the push rod 8, the adjusting rod 7 and the adjusting groove 6. Then, in the power-on state, the cross bar 11 can be pulled reversely again, and with the cooperation of the docking teeth 13, the positioning sleeve 9 is sleeved on the adjusting roller 5, and the adjusting roller 5 and the guide rod 12 are connected again, facilitating the automatic opening and closing operation. At the same time, when the window sash 2 is manually opened and closed, the movable sleeve 10 moves leftward. At this time, the pull rope 101 is in a relaxed state. Under the action of the limit spring 103, the limit roller 102 pops out and is inserted into the limit groove 104 to limit the position of the limit head 25. At this time, when the window sash 2 is manually opened and closed again, the limit head 25 no longer moves with the window sash 2, and the cleaning seat 14 can be pulled up by the high-strength nylon thread 24. The limit head 25 can adaptively rotate on the limit roller 102, and the positioning rod 15 slides stably in the positioning groove 16. At the same time, the gear 19 meshes with the tooth block 20 to drive the water guide roller 18 to rotate, so that the water in the water tank 17 can reach the water guide holes 21 on the water guide roller 18 through the water passing holes 22. With the rotation of the water guide roller 18, the water in the water guide holes 21 flows through the external water passing holes 22 to the glass and the cleaning roller 23 to clean the glass. When the window sash 2 is reset, the cleaning seat 14 moves downward to its original position under its own gravity. At the same time, the limit head 25 can enter the interior of the two rubber L-shaped rods fixed on the window sash 2 from above under the pull of the high-strength nylon thread 24, maintaining the reset of the position of the limit head 25, facilitating the limit head 25 to move again when the window sash 2 is automatically opened and closed subsequently. When the glass needs to be cleaned, water can be added to the water tank 17 in advance from the top opening of the cleaning seat 14 to clean the glass;

[0041] Next, after the window sash 2 is automatically opened, in case of rainy weather, rainwater enters the water collecting hopper 29. When the rainfall is large, there is more rainwater in the water collecting hopper 29. The rainwater drives the mounting rod 28 to move downward by gravity. The mounting rod 28 contacts the pressure sensor 261. The pressure sensor 261 transmits a signal to the single-chip microcomputer in the controller 3 to control the start of the motor 4, realizing the automatic closing of the window sash 2. At the same time, as the mounting rod 28 moves downward, the ejector rod 33 enters the water leakage hole 30 and pushes up the plugging block 32. At this time, there is a gap in the water leakage hole 30, and the water in the water collecting hopper 29 can flow out from the water leakage hole 30, reducing the weight of the water collecting hopper 29. Under the action of the elastic telescopic rod 27, the mounting rod 28 is reset, facilitating the next use of the water collecting hopper 29.
