1. Field of the Invention
The present invention relates to a flow rate stabilizer with a connecting tube, which is provided for fresh water pipes to make the flow rate stabilized.
2. Description of the Prior Art
Conventional flow rate stabilizer, as disclosed in TW 1338756, is provided for being installed in the flow way by using an elastic member to abut against a slidable fulcrumor plunger. The stabilizer has an elastic member for pushing a sliding plunger and fulcrum. When the water pressure of the water supply is increased, the plunger is pushed by water. The plunger is then moved to obstruct the flow way partially. As such, increment of flow rate is slashed even the water pressure is suddenly increased. When the water pressure of the water supply is decreased, the plunger is pushed by the elastic member. The plunger is then moved forward to open the flow way. As such, decrement of flow rate is minimized. The flow rate is stabilized overall. Therefore, the flow rate stabilizer can be applied to be disposed in faucets, shower nozzles, and normal water pipes.
However, when disposing the flow rate stabilizer in faucets or shower nozzles, the fixing method of inserting and compressing is inconvenient to disassemble.
Furthermore, speaking of the situation that an inner dimension of an installing hole is too small, the flow rate stabilizer would not be applicable.
The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages.
The main object of the present invention is to provide a connecting tube with a flow rate stabilizer which has a function of stabilizing a water flow and an ability of adapting to various sizes of water pipes and shower nozzles.
To achieve the above and other objects, a connecting tube with a flow rate stabilizer of the present invention includes a flow rate stabilizer and a connecting portion.
The flow rate stabilizer has a main body and an elastic ring. The main body is formed with a top surface and a bottom surface, the main body is formed with an annular guiding wall, an annular abutting wall, and an annular bottom wall. The annular receiving groove is defined by the guiding wall, the abutting wall, and the bottom wall. The receiving groove extends axially from the top surface, having an opening. The guiding wall extends conically from the opening to the bottom wall, and the abutting wall extends axially form the opening to the bottom wall. The bottom wall has an arc-shaped cross-section. The main body is formed with a plurality of penetrating holes which extend axially and communicate axially with the receiving groove. At least a part of a figure of each penetrating hole covers a figure of the guiding wall axially.
The elastic ring is received in the receiving groove. Parts of the elastic ring near the penetrating holes are movable between a first position and a second position along the bottom wall, abutting against to the bottom wall when the elastic ring is located at the first position. The elastic ring abuts against the bottom wall and moves into the penetrating holes when the elastic ring is located at the second position. As a result, a part of each penetrating hole is blocked by the elastic ring when the elastic ring is located at the second position. Also, the elastic ring has a tendency to move back to the first position at anytime.
The connecting portion is divided into a first part and a second part. The first part has a first opening, and the second part has a second opening. The first opening communicates with the second opening. The flow rate stabilizer is disposed between the first part and the second part.
By what is mentioned above, the present invention provides a connecting tube with a flow rate stabilizer. The connecting tube with the flow rate stabilizer uses the elastic ring moving in the receiving groove. Therefore, the elastic ring is able to move in the receiving groove so as to obstruct the flow way partially making the flow rate stabilized. The structure of the connecting portion enables the present invention to be adapted to various water pipes. As such, manufacturing is uncomplicated, and lifetime is prolonged.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

The main body 10 is further formed with a plurality of penetrating holes 14. Each penetrating hole 14 extends axially and communicates axially with the receiving groove 13. That is, each penetrating hole 14 has an outline which is enclosed in an outline of the receiving groove 13. In other words, outlines of the penetrating holes 14 are located in the outline of the receiving groove 13, and do not pass through the outline of the receiving groove 13. At least a part of a figure of each penetrating hole 14 covers a figure of the guiding wall axially. Preferably, the guiding wall 131 has an outline which is adjacent to the opening touches tangentially with outlines of the penetrating holes 14. That is, the penetrating holes 14 are arranged inside of an outer periphery of the receiving groove 13. Each penetrating hole 14 has a considerable size. Preferably, each penetrating hole 14 has a figure covering both figure of the guiding wall 131 and figure of the bottom wall 133, as shown in
The elastic ring 3 is received in the receiving groove 13. The abutting wall 132 extends axially form the opening to the bottom wall 13 so that a radius is getting smaller when the abutting wall 132 is getting closer to the bottom wall 13. For the sake of elasticity of the elastic ring 3, the elastic ring 3 stays in a smaller radius area of the receiving groove 13 without affecting by external force in order to avoid that the elastic ring 3 falls from the receiving groove 13. A part of the elastic ring 3 which is near to the penetrating holes is able to move between a first position and a second position along the bottom wall 133. Precisely, the elastic ring 3 is flexible, so the elastic ring 3 is able to stretch. A part of the elastic ring 3 which is closed to penetrating holes 14 can move to each penetrating hole 14 along the bottom wall 133, abutting against the bottom wall 133 and approaching each penetrating hole 14. Therefore, each penetrating hole 14 is blocked by the elastic ring 3 partially. For the sake of elasticity of the elastic ring 3, the elastic ring 3 has a tendency of moving back to the first position when the elastic ring 3 does not affect by external force.
Accordingly, the flow rate stabilizer 1 of the present invention can be disposed in a flow way. The top surface 11 is made toward the water source. When water is closed or is not entered, or the water pressure is low, the position of the elastic ring 3 is mainly determined by the elastic force of the elastic ring 3. The elastic ring 3 is located at the first position. The elastic ring 3 is located in the receiving groove 13 so that the elastic ring 3 is near to the bottom wall 133, as shown in
When water pressure or the speed of water flow is increased, water would push the elastic ring 3 to move along the bottom wall 133 toward the second position, as shown in
In order to adapt the stabilizer to various sizes of water pipes or shower nozzles, the present invention is further comprising a connecting portion which is adaptable for various sizes of water pipes or shower nozzles. The connecting portion is divided into a first part 21 and a second part 22. The first part 21 has a first opening, and the second part has a second opening. The first opening communicates with the second opening. The stabilizer 1 is disposed between the first part 21 and the second part 22. The stabilizer 1 and the connecting portion 2 can be fabricated together after being manufactured separately. Also, the stabilizer 1 and the connecting portion 2 can be formed integrally in a process of production. There are three kinds of the connecting portion 2 described as the followings: Firstly, the first part 21 has an outer thread, and the second part 22 has an outer thread, as shown in
When disposing the connecting tube of the present invention in the flow way, the first part 21 and the second part 22 are positioned in the corresponding pipe size respectively, and then functions can be carried out by the connecting portion 2 with the stabilizer 1. To be clearer, when an inner dimension of the water pipe is larger than that of the connecting portion 2, the water pipe can be screwed to the connecting portion 2 by the outer thread of the connecting portion 2. When an inner dimension of the water pipe is smaller than that of the connecting portion 2, the water pipe can be screwed to the connecting portion 2 by the inner thread of the connecting portion 2.
To conclude, the present invention arranges the stabilizer 1 in the connecting portion 2. With the suitable connecting portion 2, the present invention can be disposed in various flow ways or shower nozzles. And using only the main body 10 and the elastic ring 3 in the stabilizer 1 reaches purposes of keeping the supplement of the water flow stabilized and keeping the water flow stabilized in the flow way. Accordingly, the present invention is simplified in structure. The stabilizer 1 and the connecting portion 2 can also be formed integrally, leading whole structure to be more stable, and lifetime is prolonged also. On the other hand, manufacturing and producing the flow rate stabilizer is easier without other complex structures. As a result, the cost of production can be well-controlled to gain better market competition.
