Description

Technical Field

[0001] The invention relates to the technical field of bathroom devices, and in particular to a shower device capable of draining water stored inside. Background Art

[0002] Common shower devices include shower faucets, shower heads and shower kits. After the valves of these shower devices are closed after use, water will remain in the internal cavity and pipes of the shower devices. When in use, the residual cold water inside will flow out and spray onto the user, causing discomfort. In addition, the water retained inside will easily produce scale, breed bacteria or rust and damage internal parts if it remains in the pipes for a long time. In areas with low temperatures, the accumulated water inside will easily freeze and cause pipe ruptures.

[0003] In order to solve these problems, many peers have made some improvements to the existing shower devices. For example, patent number 202010869498.0 and patent name are a shower faucet with drainage function. A constant temperature valve core and a water diversion valve core are arranged in the faucet body. A rotating seat, a fixed valve plate and a moving valve plate are arranged in the water diversion valve core. At least three water outlets are opened on the fixed valve plate. The bathtub water outlet, the overhead shower assembly and the handheld spray head assembly are respectively connected to the corresponding water outlet holes. A connecting groove is opened on the lower surface of the moving valve plate. When the shower faucet is closed, the connecting groove is connected to the bathtub water outlet, the overhead shower assembly and the handheld spray head assembly. The three water outlets corresponding to the shower head assembly and the handheld nozzle assembly are all connected. When the shower faucet is closed, the three water outlets corresponding to the bathtub outlet, the overhead shower head assembly and the handheld nozzle assembly are interconnected through the connecting groove. At this time, the accumulated water in the corresponding pipes of the shower head and the shower head are collected in the connecting groove through their respective water outlets, and the bathtub outlet is located lower than the shower head and the shower head. The water in the connecting groove is discharged outward through the bathtub outlet, so that the accumulated water inside the faucet body and the pipes corresponding to the overhead shower head assembly and the handheld nozzle assembly are discharged outward through the bathtub outlet, so that the shower faucet is automatically drained when it is closed.

[0004] The above structure solves the problem that the accumulated water in the shower kit cannot be drained after the faucet is turned off. However, this faucet still uses a more traditional rotary-controlled water diversion valve core. When in use, the water diversion valve core can only be rotated to different positions by the switching rod to supply or drain water to the overhead shower assembly and the handheld shower assembly. It is inconvenient to operate and use. Users often rotate and adjust the position to the wrong position, resulting in chaotic water discharge from the overhead shower or handheld shower. At present, shower bodies with multiple key valve cores (commonly known as piano keys) have been widely popularized in the market, and the water diversion valve core in the above structure cannot be modified to be suitable for piano keys to be independently installed in the key valve core shower body for drainage, which cannot meet consumer needs.

[0005] Moreover, this rotary water-dividing valve core needs to control the water outlet and drainage of the overhead shower, hand-held showerhead and bathtub at the same time, and too many water outlet holes need to be opened on its fixed valve plate. This water-dividing valve core is usually designed with side water inlet (at least three water inlet holes are opened on the side wall of the shell) and bottom water outlet mode, which leads to a complex structure of the water-dividing valve core, and sealing failure problems are prone to occur between the fixed valve plate and the moving valve plate. The sealing connection between the water-dividing valve core and the shower body is also difficult to handle. Poor sealing can easily lead to water cross-talk between different water channels.

[0006] In addition, in the above structure, the water inlet of the handheld spray head assembly is downwardly arranged at the bottom of the faucet body, and its interface position is lower than the bathtub spout. The accumulated water at the elbow of the handheld spray head assembly connecting pipe cannot be discharged through the bathtub spout, and a large amount of accumulated water will remain in the pipe of the handheld spray head assembly. Summary of the invention

[0023] The control valve 5 is an independent component that is easy to be installed in the shower body 1, and is easy to be independently controlled and operated through the control button. The control valve 5 is provided with a valve core seat 51, a fixed valve plate 52, a movable valve plate 53, an operating rod 54, a mounting cylinder 55 and a lever seat 56. The valve core seat 51 is sealed and connected to the bottom surface of the valve cavity 12. The valve core seat 51, the fixed valve plate 52 and the lever seat 56 are fixedly connected to the mounting cylinder 55.
