Full-automatic closed floor drain

Abstract

The invention discloses a floor drain which comprises an upper cover and an outer frame surrounding the outer side of the upper cover. A certain amount of running water gaps are arranged above the upper cover, and a floor drain body is arranged below the upper cover. A middle layer board is further arranged in the outer wall of the floor drain body, and the upper cover is connected with the middle layer board through a connection pillar. A clamping position provided with a concave portion extends upwards from the edge of the middle layer board, and a water seal can be formed by the clamping position and the downwards-protruding portion of the outer frame. A containing cavity for containing accumulated water is formed by the middle layer board, and a supporting pillar extends downwards from the bottom of the inner side of the middle layer board. A drainage hole is further formed in the middle layer board, the clamping position with a concave portion is arranged outside the drainage hole, and a water seal can be formed by the clamping position and the protruding portion of the bottom end of a drainage valve. Portions, opposite in position, of the middle layer board and the upper cover are provided with two sets of magnets respectively, wherein the magnets are opposite in magnetic pole. The magnet located below is provided with a guiding pillar, and a containing pillar is arranged on the outer side of the guiding pillar. The floor drain can be automatically opened according to the drainage amount, and the good water sealing and leakage preventing effects are achieved.

Description

technical field [0001] The invention relates to a floor drain, which can be automatically opened and closed according to the amount of water discharge, and is airtight when it is not in use, has a good deodorizing effect, and has the function of preventing leakage, and can meet the requirements of high-power drainage. needs. Background technique [0002] Most of the drainage floor drains currently used in the city, such as those installed in toilets or laundry rooms, have a simple structure, including a screen-like metal cover and a sewer pipe below. [0003] The floor drain of this structure has the defects of the following aspects: 1. The sewer pipe of the floor drain is at a vertical angle to the horizontal plane of the indoor ground, as shown in the attached manual. figure 1 As shown, in such a floor drain design, the sewer pipe 2 is at a vertical angle to the horizontal plane of the ground waterproof layer 1; at present, the waterproof treatment of the floor drain is u...

Problems solved by technology

[0003] The floor drain of this structure has the defects of the following aspects: 1. The sewer pipe of the floor drain is at a vertical angle to the horizontal plane of the indoor ground, as shown in the attached manual. figure 1 As shown, in such a floor drain design, the sewer pipe 2 is at a vertical angle to the horizontal plane of the ground waterproof layer 1; at present, the waterproof treatment of the floor drain is usually realized by brushing the waterproof layer on the sewer pipe 2, because the sewer pipe 2 is perpendicular to the ground, brushing The waterproof layer is not easy to operate, and the protection of the waterproof layer is often not comprehensive when brushing the waterproof layer, so that water leaks from the junction of the sewer pipe of the floor drain and the ground waterproof layer 1; When the floor drain is not used for a long time, the water seal of the floor drain will dry up, and the floor drain will no longer have the anti-odor function; third, in order to achieve the anti-odor function, the original floor drain often has other structures in the sewer pipe, which in fact reduces the amount of sewage. The effect of the drainage cross section of the pipeline reduces the drainage effect. At present, the floor drains on the market all have the disadvantage that when the deodorization effect is strong, the drainage speed becomes slow, and when the drainage speed is strong, the deodorization function will decline; 4. The existing floor drains do not have The function of filtering small items such as hair, while the floor drain filter needs to filter hair, so a high-mesh filter must be used. Currently, the filter used in the market is usually a filter with a size of less than 10 mesh, which can only intercept larger foreign objects. It can't intercept small objects such as hair at all
