Description

Technical Field

[0001] This utility model belongs to the field of hardware and sanitary ware technology, specifically a shower head drain connector. Background Technology

[0002] Shower heads are commonly used devices for daily showering. They need to be connected to the faucet and shower head pipe through a special connector to ensure a stable flow of water from the faucet to the shower head, thus guaranteeing the water supply for showering. As a key connecting component of the bathroom system, the rationality of the shower head connector directly affects the water flow transmission effect. It is a basic component to ensure the normal use of the shower head and to connect the upstream and downstream water lines of the bathroom.

[0003] Current showerheads have the following drawbacks: they require manual operation to drain residual water, water can easily stagnate due to forgetting to do so, some connectors with drainage functions rely solely on gravity for slow drainage, residual water in the pipes can easily breed bacteria causing skin problems, form scale leading to pipe corrosion and shortening service life, and users need to drain cold or smelly water before the next use, resulting in a poor showering experience; therefore, a showerhead drainage connector is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing showerheads, a showerhead drain connector is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The shower head drain connector of this utility model includes a connector body assembled between the shower head pipe and the shower head body. The connector body is provided with a first boss and a second boss, and a flow channel is formed between the two. A baffle is rotatably assembled in the connector body by a torsion spring. The baffle initially blocks the outlet of the flow channel. A drainage channel is provided on one side of the connector body. A blocking block is provided on the baffle that seals with the inlet of the drainage channel. When the baffle is pushed to rotate by the liquid in the flow channel, the blocking block blocks the drainage channel. When the baffle blocks the flow channel, the blocking block disengages from the inlet of the drainage channel.

[0006] Preferably, the flow channel is a Venturi tube structure, and the flow channel includes a large-diameter section near the faucet and a small-diameter section near the shower head pipe.

[0007] Preferably, an arc-shaped bevel is provided between the large-diameter section and the small-diameter section.

[0008] Preferably, the first protrusion has a channel that connects the small-diameter section to the drainage channel. When the faucet is turned on and fluid flows through the channel, the air in the drainage channel is drawn out through the channel by Bernoulli's principle, creating a negative pressure inside.

[0009] Preferably, a first check valve is provided on the inner wall of the drainage channel near the outlet, the first check valve allowing fluid to be discharged from the drainage channel to the outside.

[0010] Preferably, a second one-way valve is provided in the channel, which allows air in the drainage channel to enter the flow channel.

[0011] Preferably, the drainage channel has a cavity.

[0012] Preferably, the two ends of the connector body are connected to the shower head body and the shower pipe through internal threads.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a shower drain connector that, through the synergistic effect of a mechanical linkage structure and a negative pressure suction structure in the Venturi tube flow channel, automatically switches between sealing the drain channel during showering to ensure water supply and opening the channel to drain residual water after use, without manual operation. Simultaneously, the Venturi tube flow channel generates and accumulates negative pressure, significantly increasing the suction speed and drainage efficiency of residual water compared to relying solely on gravity drainage. This reduces water accumulation in the shower pipe, preventing bacterial growth and skin problems caused by residual water, preventing scale and corrosion, and extending the lifespan of pipes and connectors. Furthermore, there is no need to pre-drain cold or odorous water for the next use, significantly improving shower convenience and comfort. The overall structure is simple and reliable, compatible with most faucets and shower pipes, and easy to promote and apply. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-3The present invention discloses a shower head drain connector, comprising a connector body 1 assembled between a shower head pipe 02 and a shower head body 03. Both ends of the connector body 1 are connected to the shower head body 03 and the shower head pipe 02 via internal threads. The connector body 1 has a first boss 2 and a second boss 3, forming a flow channel 4 between them. A baffle 5 is rotatably mounted inside the connector body 1 via a torsion spring. The baffle 5 initially blocks the outlet of the flow channel 4. A drainage channel 6 is provided on one side of the connector body 1. A blocking block 7 is provided on the baffle 5 to seal the inlet of the drainage channel 6. When the baffle 5 is blocked by the flow channel 4... When the liquid pushes the rotation, the block 7 blocks the drain channel 6. When the baffle 5 blocks the flow channel 4, the block 7 disengages from the inlet of the drain channel 6. During operation, when the faucet 01 is closed and there is no water flow, the torsion spring is in a natural deformation state. Its elasticity will keep the baffle 5 in its initial position. At this time, the baffle 5 tightly fits and blocks the outlet of the flow channel 4, blocking the water flow in the shower body 03 from the path of the flow channel 4. At the same time, the block 7 on the baffle 5 is completely separated from the inlet of the drain channel 6, and the drain channel 6 and the shower body 03 are in a smooth state. At this time, the water remaining in the upper part of the shower body 03 and the connector body 1 will flow along the drain channel 6 under the action of gravity. Drainage channel 6 drains naturally; when faucet 01 is opened, water flows into the flow channel 4 of connector body 1, and the water flow exerts a continuous thrust on baffle 5. This thrust is greater than the elastic force of the torsion spring, causing baffle 5 to rotate around the rotation axis. As baffle 5 rotates, its blockage of the outlet of flow channel 4 gradually dissipates, and water can flow normally through flow channel 4 to shower body 03, meeting shower needs. At the same time, the block 7 on baffle 5 moves synchronously towards the inlet of drainage channel 6 until the block 7 is completely sealed to the inlet of drainage channel 6, blocking drainage channel 6 and preventing water leakage from drainage channel 6. When faucet 01 is closed again, the water thrust disappears, and the torsion spring... The spring force will cause the baffle 5 to rotate in the opposite direction and reset, re-blocking the outlet of the flow channel 4 and causing the block 7 to disengage from the inlet of the drainage channel 6, thus reopening the drainage channel 6 and realizing the automatic discharge of residual water. Through the mechanical linkage of water flow thrust and torsion spring force, the drainage channel can be blocked during showering to ensure water supply, and the drainage channel can be opened automatically after use to discharge residual water, preventing residual water from becoming a breeding ground for bacteria and mold, reducing the occurrence of skin diseases. At the same time, it can prevent residual water from forming scale and rusting the inner wall, extending the service life of the shower body 03. Moreover, there is no need to drain cold water or odorous water first when using it next time, and the water at a suitable temperature will come out directly, improving the comfort of showering.

[0024] Furthermore, the flow channel 4 is a Venturi tube structure, comprising a large-diameter section 401 near the shower head pipe 02 and a small-diameter section 402 near the shower head body 03. An arc-shaped bevel is provided between the large-diameter section 401 and the small-diameter section 402. A channel 11 is provided on the first boss 2, connecting the small-diameter section 402 to the drainage channel 6. When the faucet 01 is turned on and fluid flows through the flow channel 4, the Bernoulli principle draws air out of the drainage channel 6 through the channel 11, creating a negative pressure inside. A first one-way valve 8 is provided on the inner wall of the drainage channel 6 near the outlet. The first check valve 8 allows fluid to be discharged from the drain channel 6 to the outside. A second check valve 9 is provided in the channel 11. The second check valve 9 allows air in the drain channel 6 to enter the flow channel 4. The first boss 2 is provided with an assembly part for assembling the second check valve 9. The first check valve 8 and the second check valve 9 have the same structure. During operation, when the faucet 01 is opened, water flows into the flow channel 4 from the large diameter section 401. Due to the reduced cross-sectional area of ​​the small diameter section 402, the water flow velocity will significantly increase. According to Bernoulli's principle, the higher the fluid velocity, the lower the pressure. The pressure will be lower than the pressure in the drainage channel 6, creating a negative pressure difference. This negative pressure difference will exert a suction effect on the drainage channel 6 through the channel 11. At this time, the second one-way valve 9 in the channel 11 will open under the negative pressure, and the air in the drainage channel 6 will be continuously drawn into the flow channel 4, mixed with the water flow, and then flow to the shower body 03. At the same time, the first one-way valve 8 at the outlet of the drainage channel 6 will close due to the negative pressure in the channel, completely sealing the outlet of the drainage channel 6 and preventing external air from entering. As the air is continuously drawn out, the negative pressure in the drainage channel 6 will gradually increase. During this process, the water flow thrust will push the baffle. 5. Rotate to block the inlet of the drain channel 6 with the block 7, preventing water from entering the drain channel 6 and ensuring that the negative pressure only accumulates in the drain channel 6. When the faucet 01 is closed, the water flow thrust disappears, and the torsion spring drives the baffle 5 to reset. At the same time, the baffle 5 re-blocks the outlet of the flow channel 4, and the block 7 disengages from the inlet of the drain channel 6, connecting the drain channel 6 with the shower body 03. At this time, the negative pressure accumulated in the drain channel 6 will generate a suction effect, quickly drawing the residual water in the shower body 03 into the drain channel 6, and then quickly discharging it through the outlet of the drain channel 6. Compared with gravity drainage, the residual water suction speed is increased.

[0025] Furthermore, a cavity 10 is provided in the drainage channel 6; during operation, the cavity 10 in the drainage channel 6 can buffer the air flow when the faucet is turned on and negative pressure is accumulated, avoid sudden drops in local pressure and turbulent noise, and make the negative pressure rise steadily. When the faucet is turned off and residual water is sucked up, the negative pressure can be evenly transmitted to prevent it from being instantly canceled out by the influx of water, so that the residual water is drained more thoroughly.

[0026] The conventional valve core structure, sealing material, and opening pressure threshold of the first one-way valve 8 and the second one-way valve 9 in this utility model are all conventional technologies in the field. The commonly used manufacturing materials of the connector body 1, such as brass and engineering plastics, and the conventional sealing types that are compatible with the first one-way valve 8 and the second one-way valve 9 are all well known to those skilled in the art. They are not the innovation of this utility model, so they will not be described in detail here.
