Description

Deodorant floor drain with alarming function

Technical Field

The invention belongs to the technical field of articles for daily use, and relates to a floor drain, in particular to a deodorization floor drain with an alarm function.

Background

The floor drain is a device which is frequently used for removing indoor accumulated water in kitchens, toilets, laundries and the like, and a small amount of water on the ground can be drained into a sewer through the floor drain when cleaning is carried out at ordinary times. When the water pipe leaks, bursts and the like, the accumulated water on the ground can be introduced into the drainage system through the floor drain to avoid water logging indoors. However, when the floor drain is actually used, two problems are often encountered.

Firstly, because the floor drain is directly connected with the sewer pipe, in order to prevent toxic and harmful gases in the sewer pipe from flowing backwards into a room, the pipeline below the floor drain is often provided with a bent pipe, and the gas is blocked from flowing backwards by a method of injecting water into the bent pipe. However, in the high-temperature drying season, the evaporation of accumulated water inside the elbow pipe often occurs, so that the elbow pipe loses water and loses the function of blocking gas backflow, and the indoor air is polluted. The solution for the backflow of the floor drain gas mainly comprises the steps of supplementing water into the bent pipe, avoiding the water level from being too low, and achieving the purpose of preventing the gas from flowing backwards, such as the invention patent application with the application number of 201810960396.2, the utility model patent with the patent number of 201620269737.8 and the like.

Secondly, most of the existing floor drains are provided with a plurality of strip-shaped gaps on a cover plate, so that larger objects are prevented from entering a sewer to avoid pipeline blockage. However, the disadvantage of this method is that once the water pipe with a large flow leaks, the strip gaps are easily blocked by foreign matters such as garbage caused by the water flow washing the ground, and the floor drain can not drain water completely, so that water is accumulated in the room.

Detailed Description

As shown in fig. 1 and 2, the deodorization floor drain with the alarm function sequentially comprises a control box 1, a sealing ring 2, a mounting plate 3 and a water leakage basket 4. The center of the mounting plate 3 is provided with a lower water hole, and the side wall of the lower water hole is in a step shape. The side wall and the bottom of the water leakage basket 4 are provided with water leakage holes, and the edge of the top is convex outwards. The water leakage basket 4 is inserted into the lower water hole and is limited by the step and the bulge. The sealing ring 2 is arranged between the control box 1 and the mounting plate 3.

The control box comprises a box body 11 and a box cover 12, the box body 11 and the box cover 12 enclose a working cavity, and a buzzer 5, a button switch 6, a reed switch 7 and a battery 8 which are connected in series are arranged in the working cavity. The bottom of the control box is provided with a plugging bulge 13, and the plugging bulge 13 is in a circular truncated cone shape and is matched with the size of a sewer hole. The side wall of the box body 11 is provided with a through hole 14, and the through hole 14 is parallel to the axial direction of the box body 11. A slide bar 9 is movably arranged in the through hole 14, a magnetic steel 10 is fixedly arranged at the top of the slide bar 9, and the slide bar 9 drives the magnetic steel 10 to move up and down. The reed switch 7 is arranged close to the inner wall of the box body 11, and the position corresponds to the position when the magnetic steel 10 moves to the low point. The reed switch 7 adopts a normally open type reed switch, and when the magnetic steel 10 approaches, the contact of the reed switch 7 is closed. The button switch 6 is closed at ordinary times, and when the floor drain main body needs to be pulled out, the buzzer 5 is temporarily disconnected by pressing the button switch in order to avoid long-time ringing, but the button switch needs to be detected to be in a connected state before being inserted back into the main body.

When no water is accumulated on the ground or the accumulated water amount is small, the plugging bulge 13 of the control box is embedded into the lower water hole under the action of the integral gravity of the control box and is sealed by the sealing ring 2, and the control box cuts off the sewer from the indoor gas circulation. Therefore, no matter the inside of the elbow in the sewer is accumulated with water, the polluted gas can not enter the room through the floor drain. Meanwhile, the slide rod 9 is in a jacked state, and the magnetic steel 10 is in a high position, so that a switch in the reed switch 7 is switched off, and the alarm circuit does not work.

When the indoor ground needs to be cleaned or a small amount of accumulated water is cleaned, the button switch 6 can be pressed to disconnect the circuit, so that the alarm circuit does not work. At the moment, the floor drain main body can be pulled out, and accumulated water is swept into a sewer. After the accumulated water is cleared, the button switch 6 is pressed again to turn on the circuit. At the moment, the buzzer rings, and the buzzer stops ringing after the floor drain main body is inserted into the water drainage hole.

When the water pipe leaks and leads to ground to have a large amount of ponding, when the water level lasts to rise to the certain degree, the control box rises under the effect of buoyancy, leads to sealing washer and mounting panel to break away from, and the protruding 13 of shutoff leaves the lower water hole simultaneously, and ground ponding can flow into sewer pipe through the floor drain rapidly. Meanwhile, as the control box rises, the slide bar descends, and the magnetic steel at the top end of the slide bar is close to the reed switch, the reed switch is closed, so that the buzzer 5 gives an alarm. In order to control the box to be able to rise when water is accumulated on the ground, the overall volume value (m) of the box is controlled³) It is required to be greater than the whole weight value (kg).
