Technical Field
[0001] This utility model relates to a floor drain, and more particularly to a floor drain capable of draining water and venting air. Background Technology
[0002] Nowadays, most equipment in cigarette manufacturing workshops requires the use of steam and compressed air. When the pressure of steam and compressed air reaches a certain value, excess gas needs to be discharged to release the pressure. The current exhaust method is to insert the steam or compressed air exhaust pipe into the workshop's sewer system, and cover the exhaust pipe with a floor drain to prevent steam from rising to the ground.
[0003] However, existing floor drain devices can only be connected to the exhaust pipe and do not have a drain outlet. When maintaining equipment, it is difficult for water on the ground to be drained into the sewer through the floor drain device, and dirt easily accumulates in the floor drain, making it difficult to clean.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0017] Embodiments of this utility model: such as Figures 1-3 As shown, a floor drain capable of draining and venting includes a floor drain base 1, an vent hole 2 at the center of the base plate of the floor drain base 1, an vent pipe connection pipe 3 at the center of the base plate, the lower end of the vent pipe connection pipe 3 being connected to the vent hole 2, a plurality of drain holes 4 at the base plate of the floor drain base 1, and two filters 5 installed inside the floor drain base 1.
[0018] The exhaust pipe connection pipe 3 is used to connect the exhaust pipe, allowing steam and compressed gas to be discharged into the sewer through the exhaust pipe and exhaust port 2. Wastewater generated during equipment maintenance can be filtered through filter 5 and then flow into the sewer through drain port 4.
[0019] This application achieves both the emission of excess gas and the discharge of wastewater. Impurities in the wastewater are collected in filter 5, making it easy to dispose of it in a trash can.
[0020] In one specific embodiment, the drain base 1 includes a base plate, a cylindrical side wall 6, and an annular baffle 7. The base plate is fixedly connected to the lower end of the cylindrical side wall 6, and the annular baffle 7 is fixedly mounted on the outer wall of the top end of the cylindrical side wall 6.
[0021] The cylindrical sidewall 6 is used to connect to the drain mounting hole, and the annular baffle 7 is used to contact the ground to prevent the cylindrical sidewall 6 from falling into the drain mounting hole. The outer diameter of the annular baffle 7 is larger than the diameter of the drain mounting hole.
[0022] Several annular rubber rings 8 are provided on the inner wall of the exhaust pipe connecting pipe 3. By providing the annular rubber rings 8, it is possible to prevent gas from returning to the ground through the gap between the inner wall of the exhaust pipe connecting pipe and the outer wall of the exhaust pipe when the exhaust pipe is venting gas.
[0023] The base plate of the drain base 1 has four drainage holes 4. The four drainage holes 4 are arranged at equal intervals. The four drainage holes 4 are used to drain sewage.
[0024] Furthermore, the two filters 5 have a symmetrical structure, both are semi-circular shells with open tops, and both filters 5 have semi-circular recesses 9 for avoiding the exhaust pipe connection pipe 3. Two filter screens 10 are provided on the bottom plate of each filter 5. Magnets 11 are provided on the connecting surfaces of both filters 5.
[0025] Two filters 5 are attracted together by magnet 11. After the two filters 5 are attracted together, the distance between the four filter screens 10 is equal to the distance between the four drain holes 4. When the two filters 5 are rotated, the four filter screens 10 are aligned with the four drain holes 4. At this time, sewage can flow into the sewer through the filter screens 10 and the drain holes 4. When the two filters 5 are rotated so that the positions of the four filter screens 10 and the four drain holes 4 are staggered, the bottom plate of the two filters 5 can block the four drain holes 4. At this time, the gas will not return to the ground through the drain holes 4.
[0026] The two filters 5 adopt a magnetic structure, so there is no need to disassemble the exhaust pipe when removing and installing the filters 5, which saves time and effort.
[0027] The working principle of this utility model is as follows: When the exhaust pipe is inserted into the exhaust pipe connecting pipe 3, it is necessary to ensure that the filter screens 10 on the two filters 5 and the drain hole 4 are misaligned when discharging and compressing the gas into the sewer. At this time, the bottom plate of the filter 5 is used to block the drain hole 4 to prevent the gas from returning to the ground from the drain hole 4.
[0028] When sewage needs to be discharged, rotate the two filters 5 so that the filter screens 10 on the filters 5 are aligned with the drain holes 4. The sewage flows into the sewer, and the impurities are intercepted by the filter screens 10 and remain in the filters 5. When there are many impurities, pull up the two filters 5 to separate them, and then pour the impurities into the trash can. Then, use the magnets 11 to hold the two filters 5 together and insert them into the drain base 1.
[0029] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
