Description

Applicable drainage pipe structure

The present invention relates to a technical field concerning the drainage of a sink or a washing machine, in particular, a water-dropping structure is attached to the drain pipe to prevent foreign matter from entering backwards, and it is easy to maintain the sanitation of the surrounding environment of the drain pipe.

According to the water tank or the washing machine, the water pipe or the snake-shaped drain pipe is installed at the water discharge port, and the end of the drain pipe is inserted into the water outlet arranged on the ground, and the sewage to be discharged is drained by the drain pipe. However, there are several problems that often occur when using:
1. Since the drain pipe is often only inserted into the water outlet by its end, it is often caused by accidental collision of the drain pipe during the placement of the surrounding material, so that the end of the drain pipe is more easily separated from the water outlet, causing the sewage discharge to be out of alignment with the water outlet. Instead, it vents to the ground, creating the problem of leaving the area of sewage.
2. Drainage pipe mouth No matter whether there is discharge of sewage, the diameter of the pipe mouth is always open and aligned with the water outlet, so the foreign body of the outside world produces a bad smell, and it is easier to go up the drain pipe with the water outlet, which is easy to be around the end of the drain pipe. It smells bad and affects environmental hygiene.
3.Because the drain pipe mouth is discharged or not, the diameter of the nozzle is open and aligned with the water outlet. Therefore, insects and insects such as cockroaches will go up into the gap between the drain pipe and the water outlet with the water outlet. When you go to the floor in the room, it is easy to invade the pathogens around the water outlet, which may adversely affect the environment. Therefore, it is really necessary to improve the above problems.

In view of the foregoing problems, the creator further studies and develops. Therefore, the main purpose of the present invention is to provide a water-falling structure suitable for a drain pipe, which is installed at the end of the drain pipe, is stable in positioning, and provides a one-way drainage effect. The sewage is restricted from being discharged into the water outlet only in one direction, and the foreign matter from the water outlet is blocked, so that in order to achieve the foregoing purpose, the technical means used in the present invention is to provide a water-falling structure suitable for the drain pipe. The system contains:
a pipe joint, which is in a hollow state, includes axial ends, respectively a first end and a second end, and a through hole is formed along the first end and the second end for the first end Correspondingly, a drain pipe is disposed, a toroidal shoulder ring wall is formed outside the first end, and a slot for inserting the drain pipe is formed between the inner side of the shoulder ring wall and the outer side of the first end;
a back tube, starting from one end, sequentially extending a shoulder edge, a tubular body, a valve flap that can change the opening and opening of the nozzle, wherein the outer diameter of the shoulder edge is smaller than the body Larger, the shoulder edge and the inside of the body have a flow port, the flow port is inserted and positioned by the second end of the pipe joint to combine the pipe joint with the check pipe, the check pipe a valve disc extending from one end of the body, the valve flaps respectively forming a movable wall having a conical shape on the two side walls, and a valve opening that can be opened and closed is formed between the ends of the two movable walls; The through hole and the sewage sent out from the flow port can force the valve opening to be opened, and the sewage is discharged.
Therefore, according to the technical means of this creation, a brief description of the functions that can be obtained by this creation is as follows:
1. This creation effectively prevents foreign objects from entering in reverse. The pipe joint is connected with the check pipe, and the check pipe has a valve flap which can be opened and closed, and the force of the discharge water can be used to push the two movable walls of the valve bevel, and the force of pushing the cone surface can be expanded. When the two movable walls open the valve port, the sewage can be discharged from the valve port. If the valve port is closed in the normal state, foreign objects, or insects, etc., will not easily enter the drain pipe. The utility model has the design of the anti-reverse and one-way drainage, and thus it is easy to maintain the environmental sanitation around the water outlet. Since the foreign matter is prevented from entering the drainage pipe in reverse, it is not easy to generate odor in the drainage pipe, and the practicality of the creation is excellent.
2. This creation is positioned by the slot of the pipe joint for the drain pipe, so the drain pipe will not fall off due to a slight collision, so that the drain pipe has a good positioning property.

This creation is a water-falling structure suitable for drain pipes. As shown in the first and second figures, the water-falling structure (100) of this creation contains:
A pipe joint (10), which is in a hollow state, includes axial ends, which are first and second ends (11) (12), respectively, and the first end (11) has an outer diameter slightly larger than the second end (12) The first end and the second end (11) (12) are provided with a through hole (13) in a through shape, and the first end (11) is corresponding to the drain pipe to be connected, and the sewage is allowed to pass through the through hole (12). Discharge out, please extend the outer side of the first end (11) to extend a larger diameter shoulder ring wall (14) with the shoulder ring wall (14) axially parallel to the first end (shown in Figures 2 and 5). 11), forming an annular slot (14) between the outer side of the first end (11) and the inner side wall of the shoulder ring wall (14), using the slot (14) for the drain pipe (30) to be inserted, and along The shoulder ring wall (14) is equally divided into a plurality of tabs (15), and the free end of the tab (15) extends obliquely toward the outside of the first end (11);
The drain pipe (30) surrounds the outer side of the first end (11) and is inserted into the slot (141). Also, because of the force applied by the insert, the free end of the tab (15) is forced to move outward until the drain pipe (30) The tube end can abut against the inner bottom surface of the slot (141), allowing the small elastic restoring force of the tab piece (15) to extend back obliquely toward the inner side, so that the card is suitable for the outside of the drain pipe (30). , providing multi-point card positioning and anti-shedding effect;
a back pipe (20), as shown in the second, third, and fourth figures, starting from one end, sequentially extending a ring shoulder (21), a tubular body (22), and a changeable tube The valve flap (25) with the mouth closed and opened, wherein the outer diameter of the shoulder edge (21) is larger than that of the body portion (22), and the shoulder edge (21) and the body portion (22) have a flow hole having a communication hole shape ( 23), the inner diameter of the flow port (23) is equivalent to the outer diameter of the second end (12), and the inner side wall protrudes from the number of ring ribs (24), whereby the outer diameter of the second end (12) of the pipe joint (10) corresponds Inserted into the flow port (23), the card rib (24) is pressed against the outer side of the second end (12), and the pipe joint (10) is combined with the check tube (20) as a body, and the anti-reverse The tube (20) is located at one end of the body (22) and extends a relatively flexible and tapered valve flap (25). The valve flap (25) is symmetrical with respect to the two side walls and forms a tapered surface toward the center of the check tube (20). The movable wall (261) (262) causes the two movable walls (261) (262) to be planar as seen in the third to fifth figures, respectively, but as shown in the first, third and sixth figures, It is a triangular pyramid shape from the other two opposite sides, and between the ends of the two movable walls (261) (262), a valve port (27) that can be opened and closed is formed, and the valve port (27) At the same time, the junction is like a line. When the valve port (27) is opened, the sewage is discharged through the through hole (13) and the flow port (23), and the water flow is directed toward the two movable walls of the valve flap (25). 261) (262) inside, the valve port (27) between the two movable walls (261) (262) is forced to open, as shown in the seventh figure, so that the sewage is discharged from the valve port (27).
Therefore, as shown in the fifth and sixth figures, in the normal state, the check valve (20) is inserted into the water outlet (40), so that the shoulder edge (21) can abut against the water outlet (40), the body ( 22) and the valve flap (25) is located inside the water outlet (40). Due to this state, the two movable walls (261) (262) of the valve flap (25) are tapered such that the valve port (27) at the boundary between the two movable walls (261) (262) is in a closed line, thus the outlet water ( 40) The foreign body on the lower side, insects, etc., will be closed by the two movable walls (261) (262), and there is no space to enter the flow port (23) of the check tube (20), and the tube The through hole (13) of the joint (10) can effectively block the foreign matter from entering the pipe joint (10) and the drain pipe (30), thereby maintaining the cleanliness of the ground.
If there is discharged sewage, as shown in the sixth and seventh figures, when the drain pipe (30) is sent out, it will flow downward through the through hole (13) and the flow port (23), and the water will flow downward, which will affect the valve. The tapered surface of the two movable walls (261) (262) of the flap (25) generates a positive impulse. Since the valve flap (25) is flexible, the impulse causes the two movable walls (261) (262) to expand outward. Overcoming the state in which the two movable walls (261) (262) originally close the valve port (27), forcing the two movable walls (261) (262) to be separated to the outside, releasing the closed engagement state, thereby exposing the valve port (27) and The passage of the flow port (23) and the through hole (13) allows the sewage to be smoothly discharged through the through hole (13), the flow port (23), and the valve port (27); when the discharge is completed, the two movable arms (261) (262) Return to the engaged state according to its elastic restoring force, and close the valve port (27).
As shown in the eighth and ninth diagrams, the body (221) of the check tube (20) may be of an elongated type, and on the circumference side of the body (22), the radial direction is equally divided along the axial direction. Outriggers (28) (281) with different outer diameters, and larger diameter collars (28), suitable for plugging in larger diameter outlets (41), smaller diameter collars (281) ), can be applied and plugged into the smaller diameter of the water outlet (42), in order to meet the different sizes of the water outlet (41) (42), so that the check tube (20) can be applied.
The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of this creation. Therefore, the scope of protection of this creation should be as listed in the patent application scope mentioned later. .
