Detailed Description

For further illustration of the various embodiments, the utility model is provided with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present utility model. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

Referring to fig. 1 to 17, the utility model discloses a horizontal floor drain, which comprises a shell 1 and a plurality of first water inlets 10 arranged in the edge area of the shell 1, wherein a cover plate 2 is arranged at the top of the shell 1, a water outlet 20 is arranged at the bottom end of the shell 1, a plurality of drainage channels 30 are formed between the shell 1 and the cover plate 2, the drainage channels 30 are communicated with at least one first water inlet 10 and water outlet 20, a check valve 3 is respectively arranged in each drainage channel 30, and the check valve 3 is used for opening the drainage channels 30 under the action of water flow or closing the drainage channels 30 under the action of gravity.

The edge area of the casing 1 is an area close to the edge of the casing and far from the center of the casing, so that the distance between the first water inlets 10 is further, the arrangement range of the first water inlets 10 is enlarged, the ground drainage path is shortened, and the drainage speed is improved.

The water flowing into each first water inlet 10 is discharged to the water outlet 20 through the corresponding water discharge passage 30 and then discharged to the sewer through the water outlet 20, and the height of the water discharge passage 30 formed between the cover plate 2 and the housing 1 is increased to be able to provide the check valve 3 at the water discharge passage 30. Any one of odor, germs and crawlers of the sewer is likely to enter the room through any one of the drainage channels 30 and the corresponding first water inlet 10 from the water outlet 20, in order to prevent any one of odor, germs and crawlers of the sewer from entering the room, each drainage channel 30 is respectively provided with a check valve 3, and the check valve 3 can open the drainage channel 30 under the action of water flow or close the drainage channel 30 under the action of gravity. When water passes through, the water flow overcomes the gravity of the check valve 3 to drive the check valve 3 to open, and the direction of the water flow is from the first water inlet 10 to the water outlet 20, so that odor, germs, crawlers and the like in the sewer are difficult to enter the room against the water flow. When the water flow is stopped, the check valve 3 closes the drain passage 30 under the action of gravity, and odor, germs, crawlers, etc. of the sewer are difficult to enter the room under the blocking of the check valve 3.

Further, since the check valve 3 is provided in the drain passage 30, the height of the drain passage 30 may be higher than that of the related art. The floor drain has limited floor thickness, and the height of the drainage channel 30 is required to be correspondingly compressed in order to be matched with the floor drain core of the vertical floor drain, while the non-return valve 3 can meet the deodorizing function of the floor drain, so that a reserved space is not required to be reserved for installing the floor drain core, and the height of the drainage channel 30 can be correspondingly increased. The increase in the height of the drain passage 30 increases the cross-sectional area of the drain passage 30 accordingly, and even if a filter screen for intercepting foreign matters is provided in the drain passage 30, it is not easily blocked.

Referring to fig. 5 to 6, the inner side wall of the housing 1 is provided with a water blocking portion 11 located in the drain channel 30, the water blocking portion 11 is provided with a drain opening 111, the check valve 3 includes a valve body portion 31 and a rotating shaft portion 32 which are integrally connected, a lower arc-shaped groove 112 is formed at the top end of the water blocking portion 11, the rotating shaft portion 32 is rotatably arranged in the lower arc-shaped groove 112 to form the check valve 3, the check valve is rotatably arranged in the drain channel 30, and the rotating shaft portion 32 drives the valve body portion 31 to open the drain opening 111 so as to open the drain channel 30 or close the drain opening 111 so as to close the drain channel 30.

The rotating shaft part 32 is arranged at the top end of the water retaining part 11, water flows from the bottom end of the water retaining part 11 under the action of gravity, and the position of the water flow acting on the valve body part 31 is close to the position of the valve body part 31 away from the rotating shaft part 32, so that the moment of the water flow acting on the check valve 3 can be increased, and the check valve 3 is more easily jacked up by the water flow. The rotation shaft portion 32 of the check valve 3 is provided in the arc-shaped groove 111 at the tip of the water blocking portion 11, and the drain port 111 can be completely opened when the check valve 3 rotates, thereby increasing the drain diameter of the drain port 111 and increasing the drain speed.

Referring to fig. 7 to 8, the cover plate 2 is provided with a water retaining flange 21 abutting against the water retaining portion 11, the water retaining flange 21 is provided with an upper arc-shaped groove 211, the upper arc-shaped groove 211 and the lower arc-shaped groove 112 cooperate to form a rotation limiting structure of the rotating shaft portion 32, and the water retaining flange 21 cooperates with the water retaining portion 11 and the check valve 3 to form a partition structure of the drainage channel 30. The water retaining part 11 and the water retaining flange 21 are abutted to enable two sides of the water retaining part 11 to be communicated only by means of the water outlet 111, when the water outlet 111 is closed by the check valve 3, the two sides of the water retaining part 11 are also isolated, so that the water retaining flange 21, the water retaining part 11 and the check valve 3 are matched to form a partition structure of the water drainage channel 30, and odor, germs, crawlers and the like of a sewer are prevented from entering a room through the floor drain. In addition, the lower arc-shaped groove 112 of the water retaining part 11 and the upper arc-shaped groove 211 of the water retaining flange 21 cooperate to form a rotating space of the rotating shaft part 32, and can also play a limiting role on the rotating shaft part 32, so that the rotating shaft part 32 is prevented from being separated from the lower arc-shaped groove 112 in the rotating process, and the reliability of the check valve 3 is ensured.

Referring to fig. 5, a sealing piece 33 made of rubber or silica gel is provided at the edge of the valve body 31, and the valve body 31 is abutted against the water blocking portion 11 through the sealing piece 33, so that the tightness between the check valve 3 and the water blocking portion 11 is ensured, and the reliability of the partition structure of the drainage channel 30 is improved.
