Description

Technical Field

[0001] The invention relates to the field of vertical drainage sealing, and in particular to a vertical floor drain device which utilizes a gravity balance plate to automatically open and close, has the functions of preventing insects, deodorizing, and draining water smoothly, and is easy to install and has the characteristics of low manufacturing cost. Background Art

[0002] There are mainly the following types of vertical floor drains on the market. For example, the floor drains rely on gravity balance to open and close to one side at the bottom of the floor drain. This type of floor drain generally reduces the diameter of the floor drain pipe so that the balance plate will not be blocked by the outer drainage pipe wall when it is opened, or it will not be completely opened diagonally downward. In addition, the counterweight part is generally a horizontally placed structure, which occupies a small part of the drainage diameter of the floor drain pipe. The water seal floor drain does not drain smoothly. When encountering a large amount of water, water will accumulate on the top. Moreover, when it is not used for a long time, the water in the water seal will dry up and it will not be able to prevent odor and insects. There are also floor drains that use the principle of magnetic levitation. A plug is hung under the circular tube of the floor drain. Under the repulsive force of two magnets, the plug pushes up to block the drain outlet. When there is water in the floor drain, the gravity of the water presses the plug down to drain. Since the magnetic levitation plug needs to be hung on the upper floor drain pipe, the drain outlet must be reduced. In addition, when draining, the plug is at the bottom, which hinders drainage. There is also another type that is made of silicone mold, which is pressed into a flat shape at the bottom. When water flows through, the outlet is flushed open, and when there is no water, it returns to a flat shape. The disadvantage is that the drainage outlet is small and not smooth enough. Summary of the invention

[0003] The invention provides a vertical floor drain device which automatically opens and closes by utilizing a gravity balance plate. The device has a simple structure, is easy to install and disassemble, and has the functions of preventing insects, deodorizing, and draining water smoothly.

[0004] The technical solution adopted by the present invention is: according to the circular pipe of the floor drain, two balancing sealing plates with counterweights are designed, and the counterweight end is flatly designed to reduce the space occupied by the pipe; two counterweight balancing sealing plates with complementary rotating shafts are installed into the floor drain pipe, and the two sealing plates are inclined downward, and the angle is less than 180 degrees, and then an axis is passed through the middle of the pipe wall and the balancing sealing plate, and the counterweight balancing sealing plate is fixed inside the floor drain, and the counterweight balancing sealing plate can be folded and opened freely. When there is no water flow, the sealing plate end is upwardly tilted and pressed on the pipe wall under the gravity of the counterweight end, and a sealing effect is achieved. When there is water flow, the counterweight end is upwardly buoyant, and the sealing plate is downwardly subjected to the gravity of the water. Under the action of the two forces, the counterweight balancing sealing plate rotates along the axis to open the drain port, and the larger the water flow, the larger the drain port is opened. In addition, the bottom of the pipe can also be cut into an inverted V shape, and the two balancing sealing plates below are slightly larger than the pipe opening. When sealing, the balancing sealing plate is against the bevel below the floor drain pipe to achieve a sealing effect.

[0005] Based on the above technical solutions, the present invention adds a blocking device above the counterweight balancing plate to prevent foreign objects such as hair from hanging on the counterweight balancing sealing balancing plate and causing functional failure. In the middle of the blocking device is a vertical baffle plate. There is a staggered counterweight movable cavity on both sides of the baffle plate. The counterweight movable cavity is only open at the bottom. The counterweight end of the flat counterweight sealing plate below extends into the cavity and can move freely up and down in the cavity. There are at least two fixing holes at both ends of the blocking plate, which are fixed to the floor drain pipe by shafts or screws. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The technical solution of the present invention will be described below in conjunction with the accompanying drawings. The described embodiment is one of the embodiments of the present invention, rather than all the embodiments. The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed, but merely represents selected embodiments of the present invention.

[0008] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5As shown, a vertical floor drain device that automatically opens and closes using a gravity balance plate. An axis is passed through the balance sealing plate through-axis hole 3 of the two balance sealing plates and fixed in the tube wall fixing device hole 5 on the floor drain pipe 6. The two sealing plates 1 are inverted V-shaped and face downward, with an angle of less than 180 degrees. The blocking plate 7 and the counterweight movable cavity 4 are an integrally formed blocking device, which is fixed in the tube wall fixing device hole 5 on the floor drain pipe 6 through two groups of upper and lower blocking plate fixing holes 8. The tube wall fixing device holes 5 are opened on both sides of the floor drain pipe 6, 3 on each side, arranged vertically, and the internal device is fixed by the axis passing through the hole. When there is no water passing through the floor drain, the balance weight 2 tilts the sealing plate 1 at the other end downward and presses it against the wall of the floor drain pipe 6, sealing the floor drain pipe 6 to prevent insects and deodorize; when water passes through the floor drain, the balance weight 2 is subjected to buoyancy, and the sealing plate 1 at the other end is opened downward by the gravity of the water, driving the balance weight 2 to tilt upward for smooth drainage.

[0009] As attached Figure 6 , Attachment Figure 7 , Attachment Figure 8 As shown, in order to prevent foreign objects such as hair from hanging on the counterweight balance sealing plate, resulting in opening and closing failure or loose sealing, a blocking device is installed above the counterweight balance sealing plate. The blocking device is integrally formed, with a blocking plate 7 in the middle. The blocking plate 7 has blocking plate fixing holes 8 on the upper and lower sides, and is fixed to the floor drain pipe 6 through the shaft or screw passing through the pipe wall fixing device hole 5. There are offset counterweight movable cavities 4 on both sides of the blocking plate 7. The bottom of the counterweight movable cavity 4 is open, and the other sides are closed. The balance counterweight 2 below extends into the counterweight movable cavity 4 and can move freely up and down.

[0010] As attached Figure 2 As shown, the bottom of the floor drain pipe 6 can also be cut into an inverted V shape, with a small piece reserved on each side of the middle position for opening a pipe wall fixing device hole 5. The sealing plate 1 is slightly larger than the bottom opening of the floor drain pipe 6. When there is no water sealing, the sealing plate 1 is close to the bottom edge of the floor drain pipe 6 without entering the interior of the floor drain pipe 6.
