Description

Technical Field

[0001] This utility model relates to the field of water leakage protection device technology, and in particular to a leak prevention device. Background Technology

[0002] The city's water supply pipelines are old and long, and are prone to corrosion, cracking, and leakage. Therefore, it is necessary to install leak protection devices in the water supply systems of buildings to maintain the safety of household water use and protect the safety of family property.

[0003] Leak protectors are typically installed at points in the pipes prone to leaks. They are the first to detect and cut off the water supply when there is a risk of leakage or when the valve is left on, and they also transmit the information to the user so that the user can replace or repair it in a timely manner.

[0004] Existing water leakage protectors rely on the outflowing water to connect to the positive and negative metal electrodes at the bottom of the unit to detect the leakage signal and send it to the main unit. The main unit then controls the actuator to close the valve to cut off the water circuit, thus achieving the function of water leakage protection. However, the signal transmission process is easily affected by other signals and distance interference, affecting the main unit's signal reception. In addition, the structure is complex and the price is expensive, making it unacceptable for ordinary users.

[0005] Therefore, how to provide a leak-proof device with a simple structure and sensitive response is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0047] The purpose of this invention is to provide a leak-proof device that is simple in structure and highly responsive.

[0048] To achieve the above objectives, the present invention provides the following technical solution:

[0049] Please see Figures 1 to 12 This embodiment provides a leak-proof device, including: a housing assembly, a solenoid valve 200, a control assembly 300, an electrode post 400, and a battery compartment 500; the solenoid valve 200 is installed inside the housing assembly; the control assembly 300 is installed in the housing assembly and connected to the solenoid valve 200, and the control assembly 300 is used to control the opening and closing of the solenoid valve 200; the electrode post 400 passes through the bottom of the housing assembly and is connected to the control assembly 300, and the electrode post 400 is used to support the housing assembly and detect liquid and transmit signals to the control assembly 300; the battery compartment 500 is installed on one side of the housing assembly and is connected to the control assembly 300 and the solenoid valve 200 respectively to provide the energy required for its operation.

[0050] The leak-proof device provided in this embodiment is generally installed at the leak-prone point of the pipeline. Specifically, a solenoid valve 200 is installed inside the housing assembly. The solenoid valve 200 is installed on the water line. The opening and closing of the solenoid valve 200 can realize the unobstructed or cut-off of the water line. When the water line is normal, the solenoid valve will be in the open state. When the leak-proof device detects water leakage, the solenoid valve 200 will close, thereby cutting off the water line.

[0051] Meanwhile, a control component 300 and a battery compartment 500 are also provided on the housing assembly. The battery compartment provides the control component 300 and the solenoid valve 200 with the power required for normal operation. The control component 300 uses a detection element to determine whether there is a water leak in the water circuit, and controls the solenoid valve 200 to close when there is a leak. In this embodiment, the detection element is specifically an electrode post 400, which is installed at the bottom of the housing assembly. The electrode post 400 not only supports the entire leak-proof device, but it is also connected to the control component 300. It can detect whether there is water at the location of the device. If water is detected, it means that there is a water leak in the water circuit. At this time, the control component 300 will quickly cut off the water circuit through the solenoid valve 200. With this configuration, the leak-proof device will quickly cut off the water circuit when water is detected by the electrode post 400, which improves the reaction rate and sensitivity of the leak-proof device. Moreover, the device has a simple structure and low manufacturing cost.

[0052] Preferably, the housing assembly includes an upper housing 110 and a lower housing 120. The upper housing 110 is provided with an inwardly recessed receiving groove 111, and the control assembly 300 is installed in the receiving groove 111.

[0053] Specifically, such as Figures 6 to 8As shown, the housing assembly includes two parts, an upper housing 110 and a lower housing 120, which are joined together to form the outer shell of the leak-proof device. At the top of the upper housing 110, there is a square, inwardly recessed receiving groove 111, and the control component 300 is installed inside the receiving groove 111. The control component 300 can be connected to a circuit control board. By placing the control component 300 on the top of the upper housing 110 and separating it from the other components inside the housing assembly, it can effectively prevent water from entering the control component 300 and causing it to be damaged.

[0054] Preferably, the top of the receiving tank 111 is provided with an operation panel 310, which is connected to the control component 300. The operation panel 310 is provided with a reset button and an indicator light for indicating the status of the solenoid valve 200. The reset button is used to restore the solenoid valve 200 to the open state.

[0055] Furthermore, an operation panel 310 is installed on the topmost layer of the upper housing 110, that is, at the opening of the receiving groove 111. The operation panel 310 is connected to the control component 300 below via a cable. The operation panel 310 is equipped with indicator lights that can emit red and green colors. When the solenoid valve 200 is in the closed state, it indicates that there is a water leak. When the water circuit is normal and the solenoid valve 200 is in the open state, the indicator light is green. In addition, the operation panel 310 is also equipped with a reset button. After the water leak is repaired, the solenoid valve 200 needs to be reopened. Therefore, the solenoid valve 200 can be reset by using the reset button, so that the leak prevention device can work normally again.

[0056] Preferably, the upper housing 110 and the lower housing 120 are mated to form a snap-fit ​​groove 510 for engaging the battery compartment 500, in which several batteries are detachably installed.

[0057] In this embodiment, the battery compartment 500 is an independent part, which is snapped together by the upper shell 110 and the lower shell 120. When installed, the battery compartment 500 is located on one side of the leak-proof device, and several batteries can be installed inside the battery compartment 500. When the battery is depleted, it can be replaced. This design can effectively prevent water from entering the battery in the battery compartment 500, effectively protect the battery from the influence of the external environment, and thus extend the service life of the leak-proof device.

[0058] Preferably, both the inlet and outlet of the solenoid valve 200 are threadedly connected to an adapter 210, and a gasket is installed between the adapter 210 and the solenoid valve 200.

[0059] Specifically, such as Figure 9 and Figure 10As shown in this embodiment, in order to facilitate the connection of the solenoid valve 200 to the water pipe on the water line, an adapter 210 is connected to both the inlet and outlet of the solenoid valve 200. Specifically, the adapter 210 can be a 3-point quick-connect to a 4-point internal thread adapter. The internal thread of the adapter 210 can be connected to the external thread of the inlet and outlet of the solenoid valve 200. In order to ensure good sealing at the connection, a gasket is installed in the groove inside the adapter 210. That is, the gasket is located between the adapter 210 and the inlet and outlet of the solenoid valve 200, which can effectively prevent water leakage.

[0060] Preferably, the upper housing 110 and the lower housing 120 are mated to form a first through hole 220 for engaging the adapter 210.

[0061] In this embodiment, in order to fix the two adapters 210 and prevent them from shaking, a semi-circular groove is provided at the edge of the mating point of the upper housing 110 and the lower housing 120. After the upper housing 110 and the lower housing 120 are mated, the two semi-circular grooves can be spliced ​​together to form a circular first through hole 220. Moreover, the diameter of the first through hole 220 is exactly the same as the outer diameter of the location of the adapter 210. In this way, the adapter 210 can be fixed by the upper housing 110 and the lower housing 120.

[0062] Preferably, the bottom of the lower housing 120 is provided with three second through holes 121 for inserting electrode posts 400, and the three second through holes 121 are distributed in an equilateral triangle.

[0063] In this embodiment, the electrode post 400 is installed at the bottom of the lower housing 120. The lower end of the electrode post 400 will only transmit a signal to the control component 300 when it comes into contact with water. Therefore, the length of the electrode post 400 should be selected according to the actual situation. At the same time, in order to ensure that the leak-proof device can be placed stably, three second through holes 121 are evenly distributed at the bottom of the lower housing 120, and the straight line connecting the three second through holes 121 forms an equilateral triangle. Of course, the number and distribution of the electrode posts 400 can also be selected according to the actual situation, and no specific limitation is made in this article.

[0064] Preferably, a cylindrical receiving portion 122 is provided inside the lower housing 120 and around the second through hole 121. A nut 410 is installed at the end of the electrode post 400 located in the receiving portion 122. The nut 410 is used to tighten the cable used to connect the electrode post 400 and the control component 300.

[0065] Understandably, in order to fix the electrode post 400 and prevent it from moving along its axial direction, and also to prevent the cable distribution from being too messy, a cylindrical receiving part 122 is provided inside the lower housing 120 and around the second through hole 121. The end of the electrode post 400 extends into the receiving part 122. In this embodiment, a nut 410 is also installed in the receiving part 122. The nut 410 can be connected to the threaded section at the end of the electrode post 400, and the nut 410 can also press the cable.

[0066] Preferably, the interior of the receiving part 122 is filled with waterproof adhesive to prevent liquid from entering.

[0067] Furthermore, in this embodiment, waterproof adhesive is also injected into the receiving part 122. The waterproof adhesive can form a sealed structure at the bottom of the lower housing 120, that is, external water cannot enter the leak-proof device through the lower housing 120 and affect the normal operation of other components.

[0068] Preferably, the electrode post 400 is a copper post.

[0069] Understandably, in order to increase the responsiveness of the control component 300, copper pillars with better guidance and reasonable price are chosen for the electrode post 400. Of course, this is only one option, and other conductive materials can also be chosen for the electrode post 400. This article does not make any specific restrictions.

[0070] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
