阅读说明：本技术 免清理洁具下水件 (Cleaning-free sanitary ware drainage piece ) 是由 廖真荣 于 2020-07-02 设计创作，主要内容包括：目前市场上普遍提供的卫生间洗手盆、浴缸下水件,主要有翻板开闭式、上下运动开闭式(弹跳式、提拉杆式、钢丝拉推式)等。由于这些下水件的开闭或限位装置件与下水件主体连接的结构,会在使用过程中钩挂混入水中的头发等线状物。这些头发缠绕集聚在下水件的结构上,致使排水缓慢直至堵塞,需经常清理,同时由于杂物长时间的停留集聚,会滋生大量细菌,清理时很臭。再有经常装卸下水构件增加了漏水的风险,本申请的技术方案通过取消固定结构,改为限位方式,这样过水通道是连续的,无固定的结构横在过水截面里,避免了水中混入的头发等杂物的多次累积集聚,彻底解决了上述下水件容易堵塞的技术缺陷,长期保持畅通,可以做到无需清理。(The drainage parts of washroom wash basins and bathtubs which are generally provided in the market at present mainly comprise flap opening and closing type, up-and-down motion opening and closing type (bounce type, lifting rod type, steel wire pulling and pushing type) and the like. Due to the opening and closing of the drain member or the structure in which the stopper member is connected to the drain member main body, threads such as hairs mixed into the water are caught during use. The hairs are wound and gathered on the structure of the drainage piece, so that the drainage is slow until the drainage is blocked, the drainage needs to be cleaned frequently, and meanwhile, because sundries stay and gather for a long time, a large amount of bacteria can be bred, and the hairs are smelly during cleaning.

Background

The drainage parts of washroom wash basins and bathtubs which are generally provided in the market at present mainly comprise flap opening and closing type, up-and-down motion opening and closing type (bounce type, lifting rod type, steel wire pulling and pushing type) and the like. Because the opening and closing device or the limit opening and closing device is structurally connected with the lower water part main body, namely after the closing cover and the connecting rod of the closing cover are removed, the water passing channel of the lower water part has a structure which is transverse to the middle of the water passing channel or when the closing cover descends and is closed, the jacking rod and the connecting rod of the closing cover cannot be separated, and therefore, part of threads such as hairs mixed into water can be hooked on the two sides of the turning plate or wound on the structures in the using process. Therefore, the flap-type drain outlet is sometimes not closed tightly or opened difficultly due to hair clamping, and the rubber sealing ring is damaged and is not closed tightly or even falls off after a long time. The mechanical up-and-down motion type is characterized in that a large amount of hair is wound and gathered on the structure of the drainage piece after a period of time, so that drainage is slow and even blocked, frequent cleaning is needed, meanwhile, a large amount of bacteria can be bred due to long-time staying and gathering of sundries, and the drainage device is smelly and unsanitary during cleaning. The drainage member is frequently assembled and disassembled, so that the risk of water leakage is increased, the drainage member is changed into a limiting mode by canceling a fixed structure, the drainage channel is continuous, the non-structure is transversely arranged in the drainage cross section, the repeated accumulation and gathering of sundries such as hair mixed in water are avoided, the technical defect that the drainage member is easy to block is thoroughly overcome, the drainage member is kept smooth for a long time, and the drainage member can be cleaned without any need.

Detailed Description

The cleaning-free sanitary ware drainage piece can be made of metal and plastic, and in order to prevent water leakage, the joint of the rotating shaft (8 in the figure) and the drainage piece (1 in the figure) needs to be subjected to waterproof sealing treatment, so that water is prevented from leaking out of the drainage piece. In the aspect of angle control of rotation of the rotating shaft (8 in the figure), when the rotating piece (7 in the figure) ascends, the section of the rotating piece, which is in contact with the positioning rod, is horizontal; when the rotating plate (7 in the figure) is driven to descend by the rotation of the rotating shaft (8 in the figure), the section of the rotating plate, which is contacted with the positioning rod, is basically in a vertical state, so that sundries such as hair and the like hung on the rotating plate (7 in the figure) are ensured to slide into the water discharging piece and flow away along with water flow when water is next passed. The gap distance between the limiting wings of the positioning rod and a limiting ring (12 in the figure) arranged on an upper part (4 in the figure) of the lower water piece and the lower part of the lower water piece is proper, the positioning rod is ensured to be basically kept in a vertical state when being lifted, if the positioning rod cannot fall and close smoothly under the action of self gravity, the gap cannot be too small, if the hair and other sundries cannot pass through the gap smoothly, the gap width is controlled to be 4-7 times of the hair diameter, the positioning rod is as thin as possible, the space between the positioning rod and the limiting ring as well as the lower part of the lower water piece is larger, the water flowing area is large, the water drainage speed is ensured to be faster, 3-5 limiting wings are arranged, the positioning wings are ensured to be kept in balance and stable when being lifted and not to be too large, the positioning wings are basically in a vertical state, the occupied space; the insertion opening (15 in the figure) of the bayonet is in a horn shape, the insertion opening (15 in the figure) is smaller from outside to inside and is smaller than the width of the bayonet (14 in the figure) when being intersected with the bayonet, and the small size is proper, namely, the rotating piece can be ensured to be smoothly clamped, and the rotating piece can be clamped and separated from the rotating piece after being clamped.
