Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to an integrated waterproof hammer device for smart toilets. Background Technology

[0002] In pressurized pipelines, a sudden change in water flow rate can occur due to external factors (such as a valve suddenly closing, a faucet turning off, or a water pump suddenly stopping), resulting in water hammer. This hydraulic phenomenon is called water hammer or water slugging, and it can easily cause pipe bursts and damage to terminal electronic devices (such as smart toilets).

[0003] Existing waterproof hammer devices have complex structures, making them inconvenient to install and disassemble with the water inlet pipe and solenoid valve of smart toilets, thus increasing maintenance costs and time. Summary of the Invention

[0004] This application provides an integrated waterproof hammer device for smart toilets. It only requires connecting both sides of the connecting housing to the water inlet pipe and the solenoid valve. In terms of maintenance, since the device structure is easy to disassemble, users can easily inspect and repair it, reducing maintenance costs and time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated waterproof hammer device for a smart toilet. The smart toilet includes a water inlet pipe and a solenoid valve. The waterproof hammer device is disposed between the water inlet pipe and the solenoid valve. The waterproof hammer device includes a connecting shell and a buffer shell disposed at the upper end of the connecting shell. A connecting channel is provided inside the connecting shell. The two sides of the connecting channel are connected to the water inlet pipe and the solenoid valve. A buffer cavity is provided inside the buffer shell. The upper end of the connecting channel is connected to the buffer cavity. A buffer component is provided inside the buffer cavity.

[0006] Compared with the prior art, the advantages of this utility model are:

[0007] The installation process of this device is simple and quick. Just connect the two sides of the connecting housing to the water inlet pipe and the solenoid valve. In terms of maintenance, because the device structure is easy to disassemble, users can easily inspect and repair it, reducing maintenance costs and time.

[0008] When the solenoid valve suddenly closes, due to inertia, the kinetic energy generated by the water flow has nowhere to go, forming a high-pressure shock wave in the connecting channel, i.e., the water hammer effect. This high-pressure shock wave will propagate in the opposite direction along the connecting channel to the buffer chamber. By setting up a buffer component, the water flow passes through the connection between the connecting channel and the buffer chamber and pushes the buffer component upward, absorbing and dispersing the impact force, thereby slowing down the water flow speed and reducing the impact of the water hammer effect on the pipes and solenoid valve, thus effectively preventing water hammer damage to the pipes and equipment.

[0009] As an improvement, a threaded post is provided on the upper end of the connecting housing corresponding to the buffer cavity. The side wall of the buffer cavity is provided with internal threads, and the outer peripheral wall of the threaded post is provided with external threads. The internal thread of the buffer cavity is threadedly connected to the external thread of the threaded post. The lower end face of the buffer assembly abuts against the upper end face of the threaded post, which facilitates the assembly and disassembly of the buffer housing and the connecting housing, while ensuring tight contact between the connecting housing and the threaded post, thereby effectively preventing liquid or gas leakage from the connection.

[0010] As an improvement, the inner wall of the interface on one side of the connecting housing is provided with internal threads, and the outer peripheral wall of the water inlet pipe is provided with external threads. The internal threads of the connecting housing and the external threads of the water inlet pipe are threaded together. The threaded connection can be tightly joined to form a reliable seal, which can facilitate the disassembly and assembly of the water inlet pipe and the connecting housing. This connection method can withstand greater pressure and prevent liquid or gas leakage.

[0011] As an improvement, a plug is provided on one side of the interface on the other side of the connecting housing, and the solenoid valve is provided with a slot corresponding to the plug. The plug and slot are inserted into each other, which facilitates the disassembly and assembly of the solenoid valve and the connecting housing. At the same time, it can effectively reduce the space occupied by the system. This compact structural design makes the whole system more compact and easy to install and use in a limited space.

[0012] As an improvement, the diameter of the connection housing interface near the solenoid valve is smaller than that of the connection housing interface near the inlet pipe. Because the T-joint interface near the solenoid valve is thinner, water will generate a certain resistance when passing through it. This can limit the degree of turbulence in the water flow, make the water flow more stable, and prevent pressure fluctuations caused by excessive water flow.

[0013] As an improvement, the buffer assembly includes a buffer column and a buffer spring. The upper end of the buffer spring abuts against the upper wall of the buffer cavity, and the lower end of the buffer spring abuts against the upper end of the buffer column, so that the lower end of the buffer column abuts against the upper end of the threaded column. The water flows through the connection channel and the connection point of the buffer cavity and pushes the buffer column upward. The impact force is absorbed and dispersed by the elastic deformation of the buffer spring. As the water hammer effect weakens and disappears, the buffer spring will gradually return to its original shape and push the buffer column back to its initial position.

[0014] As an improvement, the outer peripheral wall of the buffer column is recessed with several mounting grooves. The waterproof hammer device also includes several sealing rings. The inner side of the sealing ring is embedded in the mounting groove, and the outer side of the sealing ring abuts against the side wall of the buffer cavity. This forms an effective sealing barrier. This design can greatly prevent water leakage from the gap between the buffer column and the shell, thereby improving the sealing performance of the entire waterproof hammer device.

[0015] As an improvement, the lower end of the buffer column is recessed inward and has a buffer groove. The presence of the buffer groove provides an additional buffer space for the water flow. When the water flow suddenly stops or changes direction, the impact energy generated can be absorbed by the air or liquid in the buffer groove, thereby reducing the intensity of the water hammer effect. By setting the buffer groove, the weight of the buffer column is reduced, making it easier for the water flow to push the buffer column upward.

[0016] As an improvement, the upper end of the buffer groove is set in a hemispherical shape. The hemispherical structure can more effectively disperse and absorb the impact force from the upper end. When the impact force acts on the upper end of the hemispherical buffer groove, the force will be evenly distributed along the curved surface, thereby reducing the pressure per unit area and improving the buffering effect.

[0023] like Figures 1 to 3As shown, an integrated waterproof hammer device for a smart toilet is disclosed. The smart toilet includes a water inlet pipe 1 and a solenoid valve 2. The waterproof hammer device 3 is disposed between the water inlet pipe 1 and the solenoid valve 2. The waterproof hammer device 3 includes a connecting housing 3.1 and a buffer housing 3.2 disposed on the upper end of the connecting housing 3.1. The connecting housing 3.1 has a connecting channel 3.1.1 inside, and the two sides of the connecting channel 3.1.1 are connected to the water inlet pipe 1 and the solenoid valve 2. The buffer housing 3.2 has a buffer cavity 3.2.1 inside, and the upper end of the connecting channel 3.1.1 is connected to the buffer cavity 3.2.1. The buffer cavity 3.2.1 has a buffer component inside.

[0024] The upper end of the connecting housing 3.1 is provided with a threaded post 3.1.2 protruding from the buffer cavity 3.2.1. The side wall of the buffer cavity 3.2.1 is provided with an internal thread, and the outer peripheral wall of the threaded post 3.1.2 is provided with an external thread. The internal thread of the buffer cavity 3.2.1 is threadedly connected to the external thread of the threaded post 3.1.2. The lower end face of the buffer assembly abuts against the upper end face of the threaded post 3.1.2.

[0025] The inner wall of the interface on one side of the connecting housing 3.1 is provided with an internal thread, and the outer peripheral wall of the water inlet pipe 1 is provided with an external thread. The internal thread of the connecting housing 3.1 is threadedly connected to the external thread of the water inlet pipe 1.

[0026] A strip 3.1.3 is provided on one side of the interface of the other side of the housing 3.1. The solenoid valve 2 is provided with a slot 2.1 corresponding to the strip 3.1.3. The strip 3.1.3 is inserted into the slot 2.1.

[0027] The diameter of the interface part of the connecting housing 3.1 located near the solenoid valve 2 is smaller than that of the interface part of the connecting housing 3.1 located near the water inlet pipe 1.

[0028] The buffer assembly includes a buffer post 3.3 and a buffer spring 3.4. The upper end of the buffer spring 3.4 abuts against the upper wall of the buffer cavity 3.2.1, and the lower end of the buffer spring 3.4 abuts against the upper end of the buffer post 3.3, so that the lower end of the buffer post 3.3 abuts against the upper end of the threaded post 3.1.2.

[0029] The outer peripheral wall of the buffer column 3.3 is recessed inward and has several mounting grooves 3.3.1. The waterproof hammer device 3 also includes several sealing rings 3.5. The inner side of the sealing ring 3.5 is embedded in the interior of the mounting groove 3.3.1, and the outer side of the sealing ring 3.5 abuts against the side wall of the buffer cavity 3.2.1.

[0030] The lower end of the buffer column 3.3 is recessed inward and has a buffer groove 3.3.2.

[0031] The upper end of the buffer groove 3.3.2 is set in a hemispherical shape.

[0032] When solenoid valve 2 suddenly closes, due to inertia, the water flow will form a high-pressure shock wave in the connecting channel 3.1.1. This high-pressure shock wave will propagate in the opposite direction along the connecting channel 3.1.1 to the buffer chamber 3.2.1. By setting the buffer column 3.3 and the buffer spring 3.4, the water flow passes through the connection between the connecting channel 3.1.1 and the buffer chamber 3.2.1 and pushes the buffer column 3.3 upward through the buffer groove 3.3.2. Then, the elastic deformation of the buffer spring 3.4 absorbs and disperses the impact force. As the water hammer effect weakens and disappears, the buffer spring 3.4 will gradually return to its original shape, pushing the buffer column 3.3 back to its initial position. At this time, the device returns to a balanced state and waits for the next water flow.

[0033] During installation, the buffer column 3.3 and the buffer spring 3.4 are placed inside the buffer cavity 3.2.1. The internal thread of the buffer cavity 3.2.1 is threadedly connected to the external thread of the threaded column 3.1.2. The internal thread of the connecting housing 3.1 is threadedly connected to the external thread of the water inlet pipe 1. The insert 3.1.3 on the other side of the connecting housing 3.1 is inserted into the slot 2.1 of the solenoid valve 2, thereby completing the installation of the integrated waterproof hammer device 3 and the waterproof hammer device 3 with the water inlet pipe 1 and the solenoid valve 2.

[0034] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
