Description

Technical Field

[0001] This invention relates to the field of water heater safety equipment technology, and more specifically, to a safety protection device for a gas water heater. Background Technology

[0002] Gas water heaters consume a large amount of air during operation, and the flue gas products after combustion are mostly CO2 and a very small amount of CO. In winter, due to the enclosed environment, incomplete combustion often produces a large amount of CO, which can lead to poisoning or injury to people indoors. Therefore, safety protection devices for gas water heaters are particularly important when in use.

[0003] A search of existing published literature revealed that patent publication number CN212930493U discloses a safety protection device for gas water heaters. This device addresses the issue that most existing water heaters are installed in kitchens and lack protective structures, making them prone to grease and dust accumulation, which can damage internal parts and reduce their lifespan. Therefore, a corresponding technical solution is needed to solve these problems. This device can provide waterproof and dust-proof protection for gas water heaters, detect leaks, and allow for gas exhaust, thus improving safety. However, this safety protection device has the following drawbacks.

[0004] While this safety device can detect gas leaks and vent them through the exhaust structure, the airflow is relatively small during the venting process. Therefore, if a large amount of gas leaks or carbon monoxide is produced, it is difficult to expel it quickly. Moreover, the exhaust structure remains open for extended periods, which can lead to cold indoor temperatures in winter. Users will eventually close the exhaust structure, making the safety device inconvenient to use and affecting its safety performance for the gas water heater. Therefore, a new safety device for gas water heaters is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety protection device for gas water heaters.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for a gas water heater, comprising a controller, wherein a distance sensor is connected to the input end of the controller, a window opening mechanism is provided on one side of the distance sensor, and a detection component is provided below the controller;

[0007] The window opening mechanism includes a sensing block disposed on one side of the distance sensor, and an L-shaped connecting plate is installed on one side of the sensing block. A first threaded collar block and an adjusting screw are provided below the L-shaped connecting plate, and a servo reduction motor is coaxially connected to one end of the adjusting screw. A pressure-relieving component is provided on one side of the L-shaped connecting plate. The distance sensor and the sensing block are on the same horizontal plane, and the sensing block and the L-shaped connecting plate are welded and fixed. The outer wall of the adjusting screw is threaded at the position of the inner wall of the first threaded collar block, and both the first threaded collar block and the adjusting screw are made of stainless steel.

[0008] Preferably, a rectangular frame plate is horizontally slidably connected to the outside of the first threaded collar block, and a locking hole is provided through the top of the rectangular frame plate and near its four corners, and the cross-sectional shape of the locking hole is circular.

[0009] Preferably, a collar support block is fixed to the outside of the distance sensor by hot melt adhesive, and a mounting block is welded to one side of the collar support block near its top. Two mounting holes with a vertical cross-sectional shape of a circle are embedded on one side of the mounting block.

[0010] Preferably, the detection component includes a gas water heater positioned below the controller. A concave connecting pipe is provided on the outer side of the gas water heater. Multiple suction pipes are welded to the inner wall of the concave connecting pipe at equal intervals. A connecting support block is welded to the inner wall of the concave connecting pipe near one end. A second threaded collar block is welded to one side of the connecting support block. A linkage screw is connected inside the second threaded collar block, and the top end of the linkage screw is coaxially connected to a drive motor for vertically moving the second threaded collar block. A connecting hose is threadedly connected to the top end of the concave connecting pipe near the connecting support block, and an intake fan is threadedly connected to the top end of the connecting hose. The output end of the extraction fan is welded to an injection pipe. One end of the injection pipe is connected to a container for collecting air. A collar cover plate is fixedly connected to the top of the container. A combustible gas sensor and a carbon monoxide sensor are sequentially connected through the top of the collar cover plate from right to left. A vent hole is provided on one side between the combustible gas sensor and the carbon monoxide sensor. The second threaded collar block is threadedly connected to the linkage screw, and the top of the linkage screw is welded to the output end of the drive motor. A guide frame plate is provided on the outside of the drive motor to provide vertical guidance for the second threaded collar block, and the inner wall of the guide frame plate is vertically slidably connected to the outside of the second threaded collar block.

[0011] Preferably, the pressure-relieving component includes a rubber strip and a support plate arranged sequentially from left to right on one side of an L-shaped connecting support plate. Multiple sleeve rings are arranged in an L-shape at equal intervals on one side of the support plate. Each sleeve ring has a support groove embedded on one side. A support column is fixedly bonded inside the support groove. The two sides of the support plate are respectively bonded to one side of the rubber strip and one end of the support column by hot melt adhesive. Both the rubber strip and the support column are made of rubber.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention employs a window opening mechanism. When the gas water heater is turned on, the geared motor drives the adjusting screw to rotate forward. The adjusting screw drives the first threaded collar block to move to the left under the action of the thread. The L-shaped connecting support plate drives the sensing support block to move to the left. When the sensing distance between the distance sensor and the sensing support block is 20 cm, the controller can stop the servo geared motor drive. When the gas water heater is turned off, the controller starts the servo geared motor to drive the adjusting screw to rotate in reverse, causing the L-shaped connecting support plate to move the window to the right and close the window. The window can be automatically opened when the gas water heater is in use to ensure that the gas water heater is in a ventilated environment. When the gas water heater is finished using, the window can be automatically closed to increase the indoor temperature. This makes the gas water heater safety protection device more convenient to use and ensures that the safety protection function can operate normally.

[0014] 2. This invention uses a detection component to draw air from outside the gas water heater into a concave connecting pipe. After detection by combustible gas sensors and carbon monoxide sensors, it can be determined whether there is a gas leak or a large amount of carbon monoxide gas being produced outside the gas water heater. Then, the drive motor is started to drive the linkage screw to rotate forward. The linkage screw drives the second threaded collar block to move vertically upward along the inside of the guide frame plate under the action of the thread. Multiple air suction pipes can play a comprehensive role in checking for gas leaks outside the gas water heater, making safety protection more comprehensive.

[0015] 3. The present invention uses a pressure-reducing component. When the L-shaped connecting support plate moves to the right, the sleeve ring supports the support column inside the support groove. The support column supports the support plate. In this way, the rubber strip and the support column can play a double buffering role, ensuring that the L-shaped connecting support plate drives the window to close stably and improving the stability of the safety protection device.

[0016] In summary, through the interaction of the above-mentioned multiple functions, firstly, the windows can be automatically opened when the gas water heater is in use to ensure a well-ventilated environment; secondly, the windows can be automatically closed after the gas water heater is finished to raise the indoor temperature; thirdly, multiple air intake pipes can comprehensively check for gas leaks outside the gas water heater; and finally, the rubber strips and support columns can provide a double buffering effect, ensuring that the L-shaped connecting plate drives the window to close stably. In conclusion, the safety protection device is more convenient to use and can effectively ensure the safety protection of the gas water heater. Attached Figure Description

[0028] In some embodiments, as shown in the appendix Figure 1-3 As shown, a rectangular frame plate 8 is horizontally slidably connected to the outside of the first threaded collar block 5.

The rectangular frame plate 8 is installed at the position of the kitchen window, and the installation block 11 is fixed to one side of the inner wall of the window by bolts inserted into the installation holes 12. In this way, the installation block 11 supports the collar support block 10, and the collar support block 10 supports the distance sensor 2.

[0029] In some embodiments, as shown in the appendix Figure 1-6As shown, the detection assembly includes a gas water heater 13 located below the controller 1. A concave connecting pipe 14 is provided on one side of the gas water heater 13. Multiple suction pipes 15 are welded to the inner wall of the concave connecting pipe 14 at equal intervals. A connecting support block 16 is welded to the inner wall of the concave connecting pipe 14 near one end. A second threaded collar block 17 is welded to one side of the connecting support block 16. A linkage screw 18 is connected inside the second threaded collar block 17, and a drive motor 19 for vertically moving the second threaded collar block 17 is coaxially connected to the top end of the linkage screw 18. A connecting hose 20 is threadedly connected to the top end of the concave connecting pipe 14 near the connecting support block 16, and an intake fan 21 is threadedly connected to the top end of the connecting hose 20. An injection pipe 22 is welded to the output end of the blower 21. One end of the injection pipe 22 is connected to a housing 23 for collecting air. A collar cover plate 24 is fixedly connected to the top of the housing 23. A combustible gas sensor 25 and a carbon monoxide sensor 26 are sequentially connected from right to left to the top of the collar cover plate 24. A vent hole 27 is provided on one side between the combustible gas sensor 25 and the carbon monoxide sensor 26. The second threaded collar block 17 is threadedly connected to the linkage screw 18. The top of the linkage screw 18 is welded to the output end of the drive motor 19. The drive motor 19 is provided with a guide frame plate 28 for vertically guiding the second threaded collar block 17. The inner wall of the guide frame plate 28 is vertically slidably connected to the outer wall of the second threaded collar block 17.

[0030] In some embodiments, as shown in the appendix Figure 1-7 As shown, the pressure relief assembly includes rubber strips 29 and support plates 30 arranged sequentially from left to right on one side of the L-shaped connecting support plate 4. Multiple sleeve rings 31 are arranged in an L-shape at equal intervals on one side of the support plate 30. Each sleeve ring 31 has a support groove 32 embedded on one side. A support column 33 is fixedly bonded inside the support groove 32. The two sides of the support plate 30 are respectively bonded to one side of the rubber strip 29 and one end of the support column 33 by hot melt adhesive. Both the rubber strip 29 and the support column 33 are made of rubber.

[0031] The working principle of this invention is as follows:

[0032] When the window automatically opens for ventilation, while someone is showering in the bathroom, the rectangular frame plate 8 can be installed at the kitchen window position by inserting screws into the locking hole 9. Then, the mounting block 11 is fixed to one side of the window's inner wall by inserting bolts into the mounting hole 12. The mounting block 11 supports the collar support block 10, which in turn supports the distance sensor 2. The back of the L-shaped connecting plate 4 is then glued to the window with hot melt adhesive. The controller 1 is set to open the window 20 cm each time the gas water heater 13 is used. When the gas water heater 13 is turned on, the controller 1 activates the servo reduction motor 7, which drives the adjustment... When the adjusting screw 6 rotates forward, the adjusting screw 6 drives the first threaded collar block 5 to move to the left under the action of the thread. The first threaded collar block 5 moves to the left along the inner wall of the rectangular frame plate 8. The first threaded collar block 5 drives the L-shaped connecting support plate 4 to move to the left. The L-shaped connecting support plate 4 drives the sensing support block 3 to move to the left. In this way, the distance between the sensing support block 3 and the distance sensor 2 begins to change. When the sensing distance between the distance sensor 2 and the sensing support block 3 is 20 cm, the servo reduction motor 7 can be stopped by the controller 1. In this way, the L-shaped connecting support plate 4 drives the window to move and open. Every time the gas water heater 13 is used, the window in the kitchen position can be opened automatically to avoid closing the window.

[0033] During gas leak detection, the intake fan 21 is activated, causing multiple intake pipes 15 to generate suction. This draws air from outside the gas water heater 13 into the concave connecting pipe 14. The air then flows through the concave connecting pipe 14 into the connecting hose 20, which then delivers the air to the injection pipe 22 and finally into the housing 23. The combustible gas sensor 25 and the carbon monoxide sensor 26 detect whether there is a gas leak or a large amount of carbon monoxide being produced outside the gas water heater 13. The detected gas is then discharged upwards through the vent 27 on the collar cover plate 24. Finally, the drive motor 19 is activated, driving the linkage screw 1... 8. When rotating forward, the linkage screw 18 drives the second threaded collar block 17 to move vertically upward along the inside of the guide frame plate 28 under the action of the thread. In this way, the second threaded collar block 17 drives the connecting support block 16 to move the concave connecting pipe 14 upward. In this way, the concave connecting pipe 14 drives the suction pipe 15 to move vertically upward along the outer wall of the gas water heater 13. In this way, multiple suction pipes 15 can comprehensively check for gas leaks on the outside of the gas water heater 13. When no gas leak is found and the gas water heater 13 is turned off, the servo reduction motor 7 can be started by the controller 1 to drive the adjusting screw 6 to reverse. In this way, the first threaded collar block 5 drives the sensing support block 3 to move to the right, and at the same time, the L-shaped connecting support plate 4 drives the window to move to the right and close.

[0034] During the buffering process, when the L-shaped connecting plate 4 moves to the right, it presses against the rubber strip 29. The sleeve ring 31 supports the support column 33 inside the support groove 32, and the support column 33 supports the support plate 30. In this way, the rubber strip 29 and the support column 33 can play a double buffering role, avoiding damage to the L-shaped connecting plate 4 from impact and collision, and ensuring that the L-shaped connecting plate 4 drives the window to close stably.

[0035] When the carbon monoxide sensor 26 and the combustible gas sensor 25 detect carbon monoxide and combustible gas, an alarm will be triggered by the buzzer on the controller 1. The controller 1 will also start the servo reduction motor 7, which will drive the adjusting screw 6 to rotate forward. The adjusting screw 6 will drive the first threaded collar block 5 to move to the left under the action of the thread. The sensing distance between the sensor 2 and the sensing support block 3 will be 50 cm, and the opening size will be 50 cm wide. In this way, the combustible gas and carbon monoxide can be quickly replaced and diluted with the outside air, which will play a safety protection role for the gas water heater.

[0036] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be elaborated on here.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
