Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic valve control, and in particular to a wireless valve control device. Background Technology

[0002] Solenoid valves are installed near the pipe connection, while gas alarms are typically installed on the wall or ceiling within a 1.5-meter radius of the gas source in the kitchen. Gas alarms are usually installed by drilling holes and screwing them in, or by directly attaching them to the wall with 3M adhesive or nail-free adhesive. There is a significant gap between the gas alarm and the solenoid valve when installed on the wall or ceiling. Existing gas alarms and solenoid valves typically achieve wireless connection via optical principles such as infrared or laser. This means the solenoid valve can wirelessly interconnect with newer infrared or laser-based gas alarm products, allowing the gas alarm to control the solenoid valve.

[0003] However, some older residential areas still use old-style solenoid valves in their gas pipelines. These old-style solenoid valves cannot be wirelessly interconnected with newer infrared or laser-based optical gas alarms. They usually require a valve wire to connect to the gas alarm, which is typically installed on the wall or ceiling within a 1.5-meter radius of the gas source in the kitchen. Because of the large distance between the gas alarm and the solenoid valve, the valve wire becomes too long, affecting the cleanliness and aesthetics of the kitchen. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes a wireless valve control device, which solves the technical problem that the large distance between the existing gas alarm and the solenoid valve leads to excessively long valve wires, affecting the cleanliness and aesthetics of the kitchen.

[0005] The technical solution of this utility model is implemented as follows: A wireless valve control device includes a housing, within which is an energized circuit board. The circuit board has a control element connected to a solenoid valve via a valve wire, and a signal receiving element connected to a gas alarm via an electrical signal. The control element and the signal receiving element are connected. By placing the wireless valve control device of this application between the gas alarm and the solenoid valve, and connecting the wireless valve control device to the solenoid valve via a valve wire and the wireless valve control device to the gas alarm via an electrical signal, a signal can be transmitted from the gas alarm to the wireless valve control device when a gas leak is detected. This achieves the purpose of closing the solenoid valve while significantly reducing the length of the valve wire, avoiding the situation where the valve wire is too long and affects the cleanliness and aesthetics of the kitchen. This solves the technical problem of existing gas alarms and solenoid valves having large gaps, resulting in excessively long valve wires that affect the cleanliness and aesthetics of the kitchen.

[0006] The control element can be an MCU chip, and the signal receiving element can be an HC-05 Bluetooth module. The MCU chip and HC-05 Bluetooth module are soldered and electrically connected on the circuit board. The gas alarm is connected to the HC-05 Bluetooth module via Bluetooth signal, and the MCU chip is electrically connected to the solenoid valve via a valve wire. When a gas leak occurs, the leaking gas is detected by the gas alarm and transmits a signal to the HC-05 Bluetooth module. The HC-05 Bluetooth module sends an electrical signal to the MCU chip, which then transmits the signal to the solenoid valve via the valve wire, controlling the solenoid valve to close.

[0007] Preferably, the signal receiving element is connected to the gas alarm via Bluetooth. Bluetooth is chosen because it consumes less power, extending the device's battery life, and it effectively reduces interference from other signals, ensuring a stable signal connection.

[0008] Preferably, a battery is housed within the housing, and the battery is connected to the circuit board. The battery provides power for the operation of the control components and signal receiving components.

[0009] Preferably, the housing is provided with screws or adhesive. When the wireless valve control device of this application needs to be hung on the kitchen wall, the wireless valve control device can be installed by screws after drilling holes or directly pasted to the wall with 3M adhesive or nail-free adhesive.

[0010] Preferably, the housing is provided with a connector that snaps onto a pipe near the solenoid valve. This application achieves the purpose of directly snapping the wireless valve control device onto a pipe near the solenoid valve by using a connector on the housing, thus enabling convenient installation of the wireless valve control device.

[0011] The housing includes an upper housing and a lower housing. The upper housing has a boss and the lower housing has a groove. The upper housing and the lower housing are connected by the engagement of the boss and the groove. The connector is detachably connected to the lower housing.

[0012] It should be noted that the pipeline near the solenoid valve described in this application refers to any pipeline located near the solenoid valve that can be snapped into the connector, even if it is snapped into a gas pipeline. This is because the wireless valve control device of this application is relatively lightweight and will not affect the normal use of the gas pipeline, as this was considered and verified during the design process. The connector has also been rounded before use to prevent damage to the gas pipeline when it is snapped into the gas pipeline.

[0013] The housing and the connector are detachably connected. The detachable connection is designed to facilitate the removal of the connector from the housing. Furthermore, the detachable connection means that the housing and the connector are molded separately, which helps reduce the molding difficulty of the housing and the connector.

[0014] Preferably, the housing is provided with a fixing groove, and a fixing block is provided on the inner wall of the fixing groove. The connector engages with the fixing block. The fixing groove provides space for the insertion of the connector, and the fixing block enables the connector inserted into the fixing groove to engage with the fixing block, thereby achieving a detachable connection between the housing and the connector. The fixing block is a protrusion provided on the inner wall of the fixing groove.

[0015] Preferably, the connector includes a connecting portion that snaps into a pipe near the solenoid valve. The connecting portion has a connecting protrusion that engages with a fixing block. At least two fixing blocks are provided on the inner wall of the fixing groove, and corresponding connecting protrusions are provided on the connecting portion. The connecting portion is designed to snap into the pipe near the solenoid valve, and the connecting protrusions are designed to engage with the fixing blocks, thus achieving the engagement between the connector and the fixing blocks. The connecting portion and the connecting protrusions are integrally connected. At least two fixing blocks correspond one-to-one with at least two connecting protrusions. This arrangement ensures uniform force distribution when the connector engages with the fixing blocks and also helps maintain the stability of the engagement between the housing and the connector. When the connecting protrusions need to engage with the fixing blocks, the two connecting protrusions are first pressed together, causing elastic deformation. Then, the elastically deformed connecting protrusion is inserted along the fixing groove. After insertion, the connecting protrusion moves in the opposite direction, recovers its deformation, and engages with the fixing block, thus achieving the engagement between the housing and the connector.

[0016] Preferably, the connecting part is provided with a C-groove adapted to the pipeline near the solenoid valve; the C-groove is an interference fit with a DN15 or DN20 pipeline. The C-groove helps ensure a close fit between the connecting part and the pipeline near the solenoid valve. The diameter of the C-groove is smaller than the diameter of the pipeline near the solenoid valve, thus ensuring an interference fit and guaranteeing that the connecting part is securely fitted onto the outside of the pipeline near the solenoid valve, preventing insecure connection of the wireless valve control device after adaptation to the pipeline.

[0017] This application features two types of C-grooves on its connection part, each with an interference fit with either a DN15 or DN20 pipe. This ensures the connection part can be connected to either DN15 or DN20 pipes. The appropriate C-groove can be selected based on the pipe specifications near the solenoid valve, thus improving the applicability of this application's connection part to pipes near both solenoid valves. A DN15 pipe corresponds to a 15mm diameter, and a DN20 pipe corresponds to a 20mm diameter. It should be noted that pipe specifications in kitchens are typically DN15 and / or DN20. In actual sales, each wireless valve control device of this application is equipped with either one interference fit connector for a DN15 pipe or one interference fit connector for a DN20 pipe.

[0018] Preferably, the opening of the C-shaped groove is provided with a guide portion; two guide portions are arranged opposite each other at the opening of the C-shaped groove in a figure-eight shape. The guide portion is provided to guide the connection between the connecting part and the pipeline near the solenoid valve, which facilitates the secure mounting of the connecting part on the outside of the pipeline near the solenoid valve. The guide portion is integrally connected to the groove wall of the C-shaped groove. A guide portion is provided on the groove wall at both the beginning and end of the C-shaped groove, and the two figure-eight-shaped guide portions guide the secure mounting of the connecting part on the outside of the pipeline near the solenoid valve.

[0019] The beneficial effects of this utility model are: This application installs a wireless valve control device between a gas alarm and a solenoid valve. The wireless valve control device is connected to the solenoid valve via a valve wire, and the wireless valve control device is connected to the gas alarm via an electrical signal. Thus, when a gas leak is detected, the gas alarm can transmit a signal to the wireless valve control device, thereby achieving the purpose of closing the solenoid valve while greatly reducing the length of the valve wire and avoiding the situation where the valve wire is too long and affects the cleanliness and aesthetics of the kitchen.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: A wireless valve control device, such as Figure 1 and Figure 2 As shown, the device includes a housing 1, within which is an electrically powered circuit board 9. The circuit board 9 has a control element connected to a solenoid valve 15 via a valve wire 14, and a signal receiving element connected to a gas alarm 16 via an electrical signal. The control element and the signal receiving element are connected. By placing the wireless valve control device 13 of this application between the gas alarm 16 and the solenoid valve 15, and connecting the wireless valve control device 13 to the solenoid valve 15 via the valve wire 14, and the wireless valve control device 13 to the gas alarm 16 via an electrical signal, a signal can be transmitted from the gas alarm 16 to the wireless valve control device 13 when a gas leak is detected. This achieves the purpose of closing the solenoid valve 15 while significantly reducing the length of the valve wire 14, avoiding the situation where the valve wire is too long and affects the cleanliness and aesthetics of the kitchen. This solves the technical problem of existing gas alarms and solenoid valves having large gaps, resulting in excessively long valve wires that affect the cleanliness and aesthetics of the kitchen.

[0029] It should be noted that in the "wireless valve control device" of this application, "wireless" means that the wireless valve control device 13 receives the electrical signal of the gas alarm 16 through the signal receiving element. Typically, the wireless valve control device 13 can be connected to the electrical signal of the gas alarm 16 through Bluetooth wireless communication technology or Star Flash wireless communication technology.

[0030] Taking an example where the control element is an MCU chip and the signal receiving element is an HC-05 Bluetooth module, the MCU chip and the HC-05 Bluetooth module are soldered and electrically connected on circuit board 9. The gas alarm 16 is connected to the HC-05 Bluetooth module via Bluetooth signal, and the MCU chip is electrically connected to the solenoid valve 15 via valve line 14. When a gas leak occurs, the leaking gas is detected by the gas alarm 16 and transmits a signal to the HC-05 Bluetooth module. The HC-05 Bluetooth module sends an electrical signal to the MCU chip, and the MCU chip transmits a signal to the solenoid valve 15 via valve line 14, controlling the solenoid valve 15 to close.

[0031] Example 2, based on Example 1, provides a wireless valve control device, such as... Figure 1 and Figure 2 As shown, the signal receiving element is connected to the gas alarm 16 via Bluetooth.

[0034] Example 5, based on any one of Examples 1 to 3, a wireless valve control device, such as... Figure 2 and Figure 3 As shown, the housing 1 is provided with a connector 2 that snaps onto a pipe near the solenoid valve. This application achieves the purpose of directly snapping the wireless valve control device 13 onto the pipe near the solenoid valve 15 by using the connector 2 provided on the housing 1, thus realizing convenient installation of the wireless valve control device 13.

[0035] The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 is provided with a boss, and the lower housing 12 is provided with a groove. The upper housing 11 and the lower housing 12 are snapped together by the engagement of the boss and the groove. The connector 2 is detachably connected to the lower housing 12.

[0036] It should be noted that the pipeline near the solenoid valve described in this application refers to any pipeline located near the solenoid valve 15 that can be snapped into the connector 2, even if it is snapped into a gas pipeline. This is because the wireless valve control device 13 of this application is relatively lightweight and will not affect the normal use of the gas pipeline, as this was considered and verified during the design process. The connector 2 has also been rounded before use to prevent damage to the gas pipeline when it is snapped into the gas pipeline.

[0037] Example 6, based on Example 5, a wireless valve control device, such as... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing 1 and the connector 2 are detachably connected. The detachable connection is designed to facilitate the removal of the connector 2 from the housing 1. Furthermore, the detachable connection between the housing 1 and the connector 2 means that the housing 1 and the connector 2 are molded separately, which helps reduce the molding difficulty of the housing 1 and the connector 2.

[0038] Example 7, based on Example 6, provides a wireless valve control device, such as... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing 1 has a fixing groove 3, and a fixing block 4 is provided on the inner wall of the fixing groove 3. The connector 2 is engaged with the fixing block 4. The fixing groove 3 is provided to provide space for the insertion of the connector 2, and the fixing block 4 is provided to enable the connector 2 inserted into the fixing groove 3 to engage with the fixing block 4, thereby achieving a detachable connection between the housing 1 and the connector 2. The fixing block 4 is a protrusion provided on the inner wall of the fixing groove 3.

[0039] Example 8, based on Example 7, provides a wireless valve control device, such as... Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the connector 2 includes a connecting part 5 that snaps into a pipe near the solenoid valve. The connecting part 5 has a connecting protrusion 6, which engages with a fixing block 4. At least two fixing blocks 4 are provided on the inner wall of the fixing groove 3, and corresponding connecting protrusions 6 are provided on the connecting part 5. The connecting part 5 is designed to snap into the pipe near the solenoid valve, and the connecting protrusions 6 are designed to engage with the fixing blocks 4, thereby achieving the engagement between the connector 2 and the fixing blocks 4. The connecting part 5 and the connecting protrusions 6 are integrally connected. The at least two fixing blocks 4 correspond one-to-one with the at least two connecting protrusions 6. This arrangement ensures uniform force distribution when the connector 2 is engaged with the fixing blocks 4, and also helps maintain the stability of the engagement between the housing 1 and the connector 2. When it is necessary to connect the protrusion 6 and the fixing block 4, firstly, the two connecting protrusions 6 are pressed towards each other, and the connecting protrusion 6 is found to be elastically deformed. Then, the connecting protrusion 6 that has been elastically deformed is inserted along the fixing groove 3. After insertion, the connecting protrusion 6 moves in the opposite direction and restores its deformation. The connected protrusion 6 that has restored its deformation is connected with the fixing block 4, so as to realize the connection between the housing 1 and the connector 2.

[0040] Example 9, based on Example 8, provides a wireless valve control device, such as... Figure 3 and Figure 5 As shown, the connecting part 5 is provided with a C-shaped groove 7 adapted to the pipe near the solenoid valve; the C-shaped groove 7 is an interference fit with a DN15 or DN20 pipe. The setting of the C-shaped groove 7 helps to ensure a close fit between the connecting part 5 and the pipe near the solenoid valve 15. The diameter of the C-shaped groove 7 is smaller than the diameter of the pipe near the solenoid valve 15, thereby ensuring an interference fit between the C-shaped groove 7 and the pipe near the solenoid valve 15. This helps to ensure that the connecting part 5 is securely fitted to the outside of the pipe near the solenoid valve, preventing the wireless valve control device 13 from being loosely connected after being adapted to the pipe near the solenoid valve 15.

[0041] The connecting part 5 of this application is provided with two specifications of C-grooves 7. These two specifications of C-grooves 7 are respectively interference-fitted with DN15 or DN20 pipes to ensure that the connecting part 5 can be connected to either DN15 or DN20 pipes. The connecting part 5 with the corresponding C-groove 7 can be selected according to the specifications of the pipes near the solenoid valve 15, thereby improving the applicability of the connecting part 5 to pipes near the two specifications of solenoid valves. The DN15 specification pipe corresponds to a pipe diameter of 15 mm, and the DN20 specification pipe corresponds to a pipe diameter of 20 mm. It should be noted that the pipe specifications in kitchens are usually DN15 and / or DN20 specifications. In actual sales, one set of the wireless valve control device 13 of this application is connected to a connector 2 that is interference-fitted with a DN15 pipe or a connector 2 that is interference-fitted with a DN20 pipe.

[0042] Example 10, based on Example 9, provides a wireless valve control device, such as... Figure 3 and Figure 5 As shown, the opening of the C-shaped groove 7 is provided with a guide portion 8; two guide portions 8 are arranged opposite each other at the opening of the C-shaped groove 7 in a figure-eight shape. The guide portions 8 are provided to guide the connection between the connecting portion 5 and the pipeline near the solenoid valve 15, which facilitates the secure mounting of the connecting portion 5 on the outside of the pipeline near the solenoid valve 15. The guide portions 8 are integrally connected to the groove wall of the C-shaped groove 7. A guide portion 8 is provided on the groove wall at both the beginning and end of the C-shaped groove 7, and the two guide portions 8 arranged in a figure-eight shape guide the secure mounting of the connecting portion 5 on the outside of the pipeline near the solenoid valve 15.

[0043] In Example 10, a circuit board 9 with control and signal receiving elements, a battery 10, an upper housing 11, a lower housing 12, and a connector 2 are prepared and soldered. The circuit board 9 and battery 10 are then installed onto the lower housing 12, and the upper housing 11 is then fastened onto the lower housing 12. A connector 2 is selected according to the specifications of the pipe near the solenoid valve 15. Two connecting protrusions 6 are then pressed together, causing elastic deformation. The elastically deformed connecting protrusion 6 is then inserted into the fixing groove 3. After insertion, the connecting protrusion 6 moves in the opposite direction and recovers its deformation. The recovered connecting protrusion 6 engages with the fixing block 4, achieving the engagement between the housing 1 and the connector 2, thus forming the present application.

Use the valve cable 14 to connect the wireless valve control device 13 to the solenoid valve 15. The wireless valve control device 13 can be connected to the gas alarm 16 in the kitchen via Bluetooth signal to complete the connection between the wireless valve control device 13, the solenoid valve 15 and the gas alarm 16.

[0045] When a gas leak occurs, the leaking gas is detected by the gas alarm 16 and a signal is transmitted to the signal receiving element. The signal receiving element sends an electrical signal to the control element, and the control element transmits a signal to the solenoid valve 15 through the valve line 14 to control the solenoid valve 15 to close.
