Abstract
Description
Technical Field
[0001] This utility model relates to a floor drain, and more particularly to a split-type floor drain. Background Technology
[0002] With increasingly stringent hygiene standards, the food industry is also raising its requirements for wastewater discharge. Currently available floor drains are not fully clean or equipped with detachable water seals. These drains vary in style, and most components are assembled using welding. 1. Excessive welds in the drain body create hygiene problems (accumulation of dirt and grime) and production risks (incomplete welds, weld porosity). 2. In floor drains, the water seal consists of upper and lower parts. Currently, the water seal is held in place by contacting the support sealing ring through the edge of the upper part. This welding fixation makes it difficult to clean, or it may be connected with bolts and nuts for easy disassembly and cleaning. However, the threads at the connection point still trap dirt and grime, failing to meet high hygiene standards. Furthermore, the support sealing ring needs to support the water seal, and the rubber material of the ring poses a risk of the water seal falling off. In actual use, this problem frequently occurs in acidic, alkaline, or high-temperature environments. Current high-level floor drain manufacturing processes involve machining individual components using molds and then assembling them by welding. The presence of welds creates unsanitary areas in the drain, and the more welds there are, the greater the manufacturing errors. Uneven welds, incomplete welds, and weld porosity all contribute to substandard hygiene during subsequent use. To solve this problem, firstly, it's crucial to maximize the use of molds to directly machine the raw parts; secondly, it's essential to minimize welding processes during product manufacturing to meet usage requirements. Utility Model Content
[0003] The purpose of this utility model is to provide a split-type floor drain to solve the problem of dirt and grime accumulating easily in the existing split-type floor drains where the upper and lower water seal bodies are assembled by welding or threaded connection.
[0004] To solve the above problems, the split-type floor drain involved in this utility model adopts the following technical solution: A split-type floor drain includes a floor drain shell for installation at a sewer inlet. The upper part of the floor drain shell has an outwardly flared fixed plate edge. A water seal lower body is supported and placed in the inner hole of the floor drain shell. The lower part of the water seal lower body has a water-holding section. The upper circumferential surface of the water seal lower body has a water outlet. A water seal upper body is inserted into the water seal lower body. The lower end of the water seal upper body is open and extends to the lower edge of the water outlet. The upper port of the water seal upper body has an outwardly flared edge. The outwardly flared edge is supported and set on the water seal lower body. A sealing ring is set between the outwardly flared edge and the water seal lower body. The sealing ring is sealed and fitted with the inner wall of the floor drain shell. A debris basket is supported and set inside the water seal upper body. A cover plate grate is set on the top of the debris basket. The cover plate grate is pressed on the fixed plate edge.
[0005] The drain housing is provided with at least three support feet on its outer periphery. Support legs are threaded onto the support feet. The lower end of the support legs is used to support the drain opening, and the upper end of the support legs is provided with a screwdriver screwing mechanism.
[0006] The bottom of the support leg is equipped with a support part for rotational anti-detachment. The support part is plate-shaped and has fixing holes at both ends.
[0007] The drain housing has a deformable part on its peripheral wall that deforms inward to form an inner protrusion and forms a groove on the outer side. The water seal lower body has an outward flange on its upper edge, and the water seal lower body is supported on the inner protrusion of the drain housing by the outward flange.
[0008] A lifting rod is provided at the opening of the upper body of the water seal, and the two ends of the lifting rod are rotatably mounted on the peripheral wall of the upper body of the water seal.
[0009] The water outlets are square and are evenly distributed on the periphery of the lower body of the water seal.
[0010] The lower surface of the outward-flared edge is a conical surface with an upward-flaring opening, and the edge of the outward-flared edge is a conical surface that matches and cooperates with the outward-flared edge.
[0011] The sealing ring is fitted onto the lower surface of the outward-flared edge, and the upper part of the sealing ring has an annular groove, into which the edge of the outward-flared edge is embedded.
[0012] The fixed plate has a water inlet structure with a high edge and a low center.
[0013] The fixed plate is square, and a tapering edge is provided around the perimeter of the fixed plate. The cover plate and grate are fitted and locked inside the tapering edge.
[0014] The lower water seal body of this invention is supported inside the drain housing, while the upper water seal body is supported on the lower water seal body via an outward-flaring edge, and a sealing ring is used to achieve a seal and prevent odor backflow. In this way, the entire drain is installed through support contact, eliminating the need for welding or threaded connections. The structure is simple and does not easily accumulate dirt. Furthermore, there is no connection between the upper and lower water seal bodies, making disassembly and cleaning convenient. Simultaneously, both the upper and lower water seal bodies are rigidly supported on the drain housing, preventing the water seal from falling off.
[0015] The drain housing of this invention is provided with at least three support feet on its outer periphery. Support legs are threaded onto the support feet, with the lower end of each support leg used to support the drain opening. The upper end of each support leg is equipped with a screwdriver-operated tightening mechanism. By tightening the support legs, the position of the drain housing can be adjusted vertically to adapt to different construction environments.
[0016] The bottom of the support leg of this utility model is equipped with a support part for rotational anti-detachment. The support part is plate-shaped and has fixing holes at both ends, which can realize the stable installation of the drain shell and prevent displacement.
[0017] The drain housing of this utility model has a deformable part on its peripheral wall that deforms inward to form an inner protrusion and forms a groove on the outer side. The upper edge of the water seal lower body has an outward flange. The water seal lower body is supported on the inner protrusion of the drain housing by the outward flange. The support structure is stable and reliable and easy to install.
[0018] The water seal upper body of this utility model is provided with a lifting rod at the opening. The two ends of the lifting rod are rotatably assembled on the peripheral wall of the water seal upper body, which can easily lift the water seal upper body for easy disassembly and cleaning.
[0019] The fixing plate of this utility model has a water inlet structure with high edges and low center, which can facilitate the water flow into the drain shell and eventually into the sewer.
[0020] The lower surface of the outward-flaring edge of this invention is a conical surface with an upward-flaring opening, and the fixing plate, near the inner hole of the drain housing, has a conical surface that matches and fits with the outward-flaring edge. This provides stable support.
[0021] The sealing ring of this invention is fitted onto the lower surface of the outward-flared edge. The upper part of the sealing ring has an annular groove, and the edge of the outward-flared edge is embedded in the annular groove. The presence of the annular groove makes the assembly between the sealing ring and the upper body of the water seal reliable and prevents the sealing ring from falling off.
