Description

Eddy current drop head

The present invention relates to a water drop head structure installed at the inlet end of a drain pipe, and more particularly to a drain function having a vortex effect, and can prevent pests or odors such as cockroaches in the drain pipe from invading the falling head of the room.

Press, the floor of the bathroom and the kitchen will be provided with a drain for the discharge of waste water, and a drop head is fixed at the joint between the drain pipe and the ground, and the drop head is usually inherently fixed to the head of the drop head on the floor, and The main body of the falling head is equipped with a drainage device that can block the odor, so that the body of the falling head can only circulate the sewage, and can block the insect ants and the odor.

For example, the new patent No. M448515, "Deodorant and Insect-Reducing Head Structure" is a conventional type of water-falling head. The blocker is locked with a bolt at the flow port, and a spring is placed on the bolt, and the block is The bolt is placed so that one end of the spring abuts against the baffle to form a closing of the flow port to achieve a deodorant and insect proof effect.

However, this customary drop head, although it can prevent insects and deodorants, can not effectively increase the displacement and drainage speed, resulting in slow drainage, poor practicality, and indeed necessary to improve.

This creator has designed the original creation by considering the design and trial sample test and the multiple corrections and improvements in view of the fact that it can prevent the insects from deodorizing the water head and can not effectively increase the displacement and the drainage speed.

The present invention provides a vortex type water drop head, comprising: a base having a water drop chamber inside, a cover body protruding from a center of the water drop chamber, and a tube body having a receiving groove in the center of the cover body. The lower end of the tube body has a stop surface, wherein the peripheral wall of the cover body has a plurality of spaced apart bent pieces, and a drain hole is formed between each bent piece; a closing piece is disposed on the base Below the drainage hole; an elastic stretching unit, the elastic stretching unit is disposed in the receiving groove inside the pipe body, and is connected downwardly to the pipe body and the closing piece, so that the closing piece is subjected to the elastic stretching unit The upper elastic stretch is closely attached to the bottom of the base to close the drain hole, and the sealing piece can be pushed by water pressure to make the drain hole open.

The bent piece is generally in the shape of a fan. When the water flows into the water drop chamber, the drain hole formed by the fan shape can generate a vortex effect, increase the water flow speed and increase the displacement.

In one embodiment, a center of the closing piece is provided with a coupling hole, and a center of the stopping surface is provided with a through hole. The elastic stretching unit comprises a limiting rod and a spring, and the limiting rod is provided with an enlarged head at one end. The other end is provided with an external thread, and the spring is sleeved on the limiting rod and accommodated in the receiving groove of the tubular body, so that the spring is elasticized between the head of the limiting rod and the stop surface of the lower end of the tubular body And the threaded end of the limiting rod is pierced by the perforation in the center of the blocking surface of the tubular body, and passes through the coupling hole of the closing piece and is locked by a screw.

The top of the tube body is further provided with a cover.

The main effect of the creation is that the drainage hole of the water-falling chamber is formed by a fan-shaped bent piece, and the fan-shaped bent piece has the effect of guiding the water flow, so that the water flow in the falling water chamber can be discharged through the drainage hole. The effect of eddy current is generated, the water flow speed is increased, the displacement is increased, and the shortage of the displacement of the insect-proof and deodorant falling head is improved.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please follow the detailed description below:

Referring to Figures 1 and 2, the vortex type water drop head of the present invention comprises: a base 1, a cover 2, a closure piece 3 and an elastic stretching unit 4.

The inside of the base 1 has a water-receiving chamber 11 , and a cover body 12 is protruded from the center of the water-receiving chamber 11 , and a tube body 13 having a receiving groove 131 is defined in the center of the base body 12 , and the lower end of the tube body 13 has a The retaining surface 132 of the through hole 133, wherein the peripheral wall of the cover body 12 has a plurality of bent pieces 121 arranged in a fan-like shape, and a drain hole 122 is formed between each of the bent pieces 121.

The cover 2 is for covering an opening that closes the upper end of the tubular body 13.

The closing piece 3 is disposed below the drainage hole 122 of the base 1 and has a coupling hole 31 at the center.

The elastic stretching unit 4 includes a limiting rod 41 and a spring 42. The limiting rod 41 has an enlarged head 411 at one end and an external thread 412 at the other end. The spring 42 is sleeved on the limiting rod. The 41 is placed in the accommodating groove 131 of the pipe body 13 and the spring 42 is bucked between the head 411 of the limiting rod 41 and the stopping surface 132 of the lower end of the pipe body 13, and the limiting rod 41 is 41 One end of the external thread 412 is provided by the through hole 133 of the blocking surface 132 of the tubular body 13 and is passed through the coupling hole 31 of the closing piece 3 to be locked by a screw A, so that the closing piece 3 is coupled with the limiting rod 41.

Referring to FIG. 3, the vortex type water drop head of the present invention can be coupled to the water drop hole 51 of the drain groove 5. When the drain groove 5 is not drained, the closing piece 3 is restrained by the spring force of the spring 42 by the spring 42. Elastically stretched upwards to make it fit tightly to the bottom of the pedestal 1 to close the drainage hole 122, forming a barrier function, thereby preventing pests from entering the room by the falling head, and preventing the odor in the drainage pipe from being diverged to the insect pest and odor prevention effect in the room. .

When the drainage is performed, as shown in FIG. 4, the water flow in the drainage tank 5 is pushed through the drainage hole 122 of the water discharge chamber 11 to the bottom of the susceptor 1 to be separated from the bottom of the susceptor 1, so that the drainage hole 122 is opened. Since the drain hole 122 is formed by the fan-shaped bent piece 121, the leaf-shaped bent piece 121 has the effect of guiding the water flow, and when the water flow in the water drop chamber 11 is discharged through the drain hole 122, Produces drainage effects such as eddy currents, thus accelerating the displacement and allowing for faster drainage. Further, since the closing piece 3 stretches the stopper rod 41 downward by the water pressure, the head portion 411 of the stopper rod 41 compresses the spring 42 downward to accumulate the elastic force, thereby imparting a normal drainage function. After the drainage is completed, the closing piece 3 can be pushed back by the resilience of the spring 42 to be closely attached to the bottom of the base 1 to close the drainage hole 122, thereby forming a barrier function, thereby constituting the insect-proof and deodorant of the original falling head. And vortex drainage function.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto; that is, the equal changes and modifications made by the majority of the patent application scope of the present invention should still be covered by this patent.
