Description

Technical Field

[0001] This utility model belongs to the field of integrated bathroom technology, and in particular relates to an odor-proof floor drain that is easy to maintain. Background Technology

[0002] Integrated bathrooms are convenient to install and have a wide range of applications, widely used in large-scale construction projects and rural bathroom renovation projects. However, the installation height of the drainage pipes under integrated bathrooms is limited, and traditional odor-proof floor drains have the following problems during use: First, they often use a single sealing structure, resulting in poor sealing performance. For example, water seals lose their sealing effect after prolonged periods of non-use due to water evaporation, and silicone one-way valve seals are prone to freezing in cold outdoor winter environments, leading to loss of sealing performance. Second, damaged one-way valve seals are difficult to maintain and require complete replacement, resulting in high maintenance and repair costs. Third, their height is relatively high, making them unsuitable for the installation height of integrated bathrooms, thus limiting their applicability. Utility Model Content

[0003] In view of this, the present invention aims to provide an odor-proof floor drain that is easy to maintain, in order to solve at least one of the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0047] The inner tube 3 is installed at its lower end inside the connecting pipe 102. A first water-permeable hole 301 is opened on the upper side wall of the inner tube 3. A partition ring is provided on the outer side of the upper end of the inner tube 3. The outer side of the partition ring is bent downward to form a bent part 303. The lower end of the bent part 303 is lower than the lower end face of the first water-permeable hole 301.

[0048] Cover plate 2, with a strip-shaped through hole 201, is installed on the inner side of the upper end of cylinder 1;

[0049] A one-way valve assembly is located between the cover plate 2 and the inner tube 3.

[0050] A square plate 101 is fixed on the outer side of the upper end of the cylinder 1, which facilitates engineering construction.

[0051] The one-way valve assembly includes an inner ring 6 and an outer ring 5. The outer side of the inner ring 6 is bent downward to form a first inclined portion 602, and a first fitting portion 601 is fixed at the lower end of the first inclined portion 602.

The inner sidewall of the second fitting portion 501 fits against the outer sidewall of the first fitting portion 601.

[0052] An annular mounting boss 103 is provided on the inner side of the cylinder body 1, and a pressure plate 4 is provided on the inner side of the upper end of the cylinder body 1. The pressure plate 4 is threadedly connected to the cylinder body 1, and an outer ring 5 is installed between the pressure plate 4 and the annular mounting boss 103. A second water-permeable hole 401 corresponding to the one-way valve assembly is opened on the pressure plate 4. An inner ring 6 is installed between the upper end face of the inner tube 3 and the pressure plate 4. An annular positioning boss 304 is provided at the upper end of the inner tube 3. The outer diameter of the annular positioning boss 304 matches the inner diameter of the inner ring 6. The inner ring 6 is installed on the outer side of the annular positioning boss 304, and the pressure plate 4 seals the upper opening of the inner tube 3. The pressure plate 4 is threadedly connected to the inner side of the cylinder body, which facilitates the replacement of the inner ring 6 and the outer ring 5, improving maintenance and repair efficiency.

[0053] The thickness of the inner ring 6 decreases from the inside to the outside, and the thickness of the outer ring 5 decreases from the outside to the inside; both the inner ring 6 and the outer ring 5 are structural components made of silicone.

[0054] An installation tube 402 is fixedly mounted on the upper end of the pressure plate 4; a positioning tube 202 is fixedly mounted on the lower end of the cover plate 2. The outer diameter of the positioning tube 202 matches the inner diameter of the installation tube 402, and the positioning tube 202 is installed inside the installation tube 402.

[0056] The lower end of the inner tube 3 is fixed with a connector 302. The outer diameter of the connector 302 is smaller than the outer diameter of the inner tube 3. The outer diameter of the connector 302 matches the inner diameter of the connecting tube 102. The connector 302 is installed on the inner side of the connecting tube 102. The design of the connector 302 plays a positioning role for the inner tube 3, which facilitates assembly.

[0057] Work process:

[0058] When this plan is implemented, if Figure 3 As shown in the figure, the arrows indicate the direction of water flow, and the dots below represent water. When the water flows in the following direction, it flows through the strip-shaped through-hole 201 of the cover plate 2 to the space between the cover plate 2 and the pressure plate 4, and flows downward through the second permeable hole 401. Under the action of gravity, the first inclined part 602 of the inner ring 6 and the second inclined part 502 of the outer ring 5 move downward, and the first fitting part 601 and the second fitting part 501 separate. The water flows to the space between the inner tube 3 and the cylinder 1. Since the lower end of the bend 303 of the inner tube 3 is lower than the lower end of the first permeable hole 301, the bend 303 divides this space into a U-shaped structure. The water flows through the U-shaped structure and the first permeable hole 301 to the inside of the inner tube 3, and connects to the drain pipe via the insertion pipe 302 and the connecting pipe 102. The water level between the inner pipe 3 and the cylinder 1 is higher than the lower end of the bend 303, forming a water seal as the first sealing structure. The one-way valve assembly composed of the inner ring 6 and the outer ring 5 is in a sealed state when there is no water flow, forming a second sealing structure. The two sealing structures play a multiple sealing role, preventing the odor in the drain pipe from flowing into the bathroom. When the bathroom is not used for a long time, the water between the inner pipe 3 and the cylinder 1 evaporates and the water seal loses its function. The one-way valve assembly can still play a sealing role. Moreover, the overall structure is compact and requires little installation height, which is convenient for the use of integrated bathrooms.
