The known cold and hot water mixing valve device is shown in Figure 13 and Figure 14, which includes a valve seat 30' and a valve core 40'. The valve seat 30' has a water inlet 30A' and a water outlet 30B'; and the valve seat 30' has a cold water channel 31', a hot water channel 32', a water outlet channel 33' and a valve core sleeve 34' . The cold water channel 31' has a cold water channel water inlet 311' and a cold water channel water outlet 312', the cold water channel water inlet 311' is located adjacent to the water inlet 30A', and the cold water channel water outlet 312' is adjacent to the valve core sleeve 34' set up. The hot water channel 32' has a hot water channel inlet 321' and a hot water channel outlet 322', the hot water channel water inlet 321' is adjacent to the water inlet 30A', and the hot water channel outlet 322 is adjacent to the valve core Set of 34' settings. The water outlet channel 33' has a water outlet channel water inlet 331' and a water outlet channel water outlet 332', the water outlet channel water inlet 331' is adjacent to the valve core sleeve 34', and the water outlet channel water outlet 332' is connected to the water outlet 30B'. Moreover, the spool 40' is arranged in the spool sleeve 34' and is arranged in a positive direction, which means that it is in a shape corresponding to the cold water channel outlet 312', the hot water channel outlet 322' and the water outlet channel inlet 331'. Inverted triangle configuration. The spool 40' is used to control the mixing ratio of the cold water in the cold water passage 31' and the hot water in the hot water passage 32', so that The mixed water after mixing the cold water and the hot water is output (water supply) from the water outlet channel 33' (the assembling corresponding relationship between the aforementioned valve seat 30' and the valve core 40' is a known technology, and will not be described in detail.).

In addition, the spool cover 34' has a virtual boundary line L', which divides the spool cover 34' into a first half 341' and a second half 342', the first half 341' is between Between the virtual boundary L' and the water inlet 30A'; the second half 342' is between the virtual boundary L' and the water outlet 30B'. Both the cold water passage 31' and the hot water passage 32' extend from the first half 341' to the second half 342', so that the cold water outlet 312' and the hot water outlet 322' are located on the second half 342' Inside. As for the water outlet channel 33', it extends from the second half 342' to the first half 341', so that the water inlet 331' of the water outlet channel is located in the first half 341'.

In the above-mentioned design, the water outlet channel 33' is located between the cold water channel 31' and the hot water channel 32', and is adjacent to each other, and must maintain a predetermined distance, thus making the diameter of each channel limited (for example: the largest possible Only 5mm), the relative amount of water that can be supplied is also limited. That is to say, the wall thickness between the cold water channel 31' (or hot water channel 32') and the water outlet channel 33' of the traditional cold and hot water mixing valve device is quite limited (for example: the maximum may only be 0.5~1mm), if simply increasing the cold water channel 31' (or the hot water channel 32') and the water outlet channel 33' will make the wall thickness between the channels thinner, resulting in insufficient structural strength. Therefore, the cross-sectional area of the cold water channel 31' (or the hot water channel 32') and the water outlet channel 33' is still limited, and it is impossible or difficult to solve the problem of increasing the water supply by simply enlarging the channel.

In addition, older apartments are usually 4-story buildings, and the water tower is usually installed on the top of the 4th floor. After years of use, scale may accumulate in the water pipes between the water tower and each floor, reducing the water flow. If the user is on the 4th or 3rd floor, the water output will be small due to the small drop and low water pressure. Unless an additional pressurized motor is added to increase the water output, it will face the annoying problem of small water output.

In between, it can avoid the problem that the channel is easy to break when drilling holes in the traditional process, can increase the wall thickness and pipe diameter of each channel at the same time, and does not need to install a pressurized motor to save costs, etc. In particular, the problem to be solved by the present invention is that the building wall pipes are easy to accumulate scale and reduce the water flow after years of use.

The part to be specially explained here is that the known structure of the mixing valve seat has the following disadvantages: 1. The older apartments or mansions are usually buildings on the 4th floor, and the water tower is usually located on the 4th floor. On the top surface, if the user is on the 4th or 3rd floor, the water pressure is likely to be low due to the small drop. 2. After years of use, scale may accumulate in the water pipes between the water tower and the floors and reduce the water flow. 3. The diameter of the end pipeline at the end of the user and used to install the hot and cold water mixing valve device is usually 5mm, and the water volume that can flow through its cross-sectional area is roughly estimated to be only 5 ² (mm)=25 units (the water output is relatively small) Small).

Design of the present invention is aimed at the various factors that aforementioned water flow is less, and has following characteristics. The first feature is that the valve seat 10 commonly used in the market is redesigned during the manufacturing process to have a separation distance S between the first channel 11 and the second channel 12 in the valve structure 10, and the first channel 11 has a first tube diameter ψ1, the second channel 12 has a second pipe diameter ψ2, the outlet channel 13 has an outlet pipe diameter ψ3, and the first pipe diameter ψ1, the second pipe diameter ψ2, and the outlet pipe diameter ψ3 are all greater than the distance S.

And wherein the second feature is that the valve core sleeve 14 has a virtual boundary line L, which is parallel to the water inlet 10A and the water outlet 10B, and divides the valve core sleeve 14 into a first half 141 and a second half 141. Two halves 142. The first half 141 is between the virtual boundary L and the water inlet end 10A, and the second half 142 is between the virtual boundary L and the second end 10B of the valve structure. The water outlet 112 of the first channel and the water outlet 122 of the second channel are both located in the first half 141 , and the water inlet 131 of the water outlet channel is located in the second half 142 . Thereby, the first pipe diameter ψ1, the second pipe diameter ψ2 and the outlet pipe diameter ψ3 can all be increased to 7mm. That is, because the water outlet channel water inlet 131 is set above the first channel water outlet 112 and the second channel water outlet 122, so that the first channel 11 and the second channel 12 are not adjacent to and staggered with the water outlet channel 13, and the second channel The water outlet 112 of the first channel, the water outlet 122 of the second channel and the water inlet 131 of the water outlet channel are arranged in an upright triangle, so not only the wall thickness between the first channel 11, the second channel 12 and the water outlet channel 13 can be increased; The pipe diameters of the first channel 11 , the second channel 12 and the outlet channel 13 . Such a design, even if compared with the pipe diameter of the end pipeline of the conventional cold and hot water mixing valve device, is only 5mm, but because the pipe diameter of the present invention can reach at least 7mm, then 7 ² /5 ² =49 /25=1.96, which is equivalent to the water output from the water outlet 132 of the water outlet channel, which is about 1.96 times the water output of the conventional water pipe, which means that the water output is approximately doubled.

In summary, the advantages and effects of the present invention can be summarized as follows.

First, it is very convenient to increase the water output without changing the diameter of the water pipe. The first pipe diameter, the second pipe diameter and the outlet pipe diameter of the present invention can all be 7mm. Even if the floor close to the water tower has a small water output due to the small drop, and the diameter of the end pipeline installed with the conventional hot and cold water mixing valve device is only 5mm, it can be used as long as the valve seat and the faucet of the present invention are installed. The water output at the household end has changed from 5 ² (mm)=25 units to at least 7 ² (mm)=49 units, and the water output is 7 ² /5 ² =49/25=1.96 times. Therefore, it is very convenient to increase the water output without changing the diameter of the water pipe.

Second, the water outlet channel of the valve seat structure does not need to be inserted between the cold and hot water channels. The present invention can apply the existing technology of manufacturing valve seat, but the length of each channel in the manufacturing process, the position of the water inlet of the first channel, the position of the water inlet of the second channel, and the position of the water inlet of the water outlet channel are different from the existing manufacturing valve seat technology. The configuration is completely different. Therefore, the valve seat of the present invention can avoid the problem that the channel wall is easily broken during the traditional process of drilling.

Third, the wall thickness and pipe diameter of each channel can be increased at the same time. Because the water inlet of the water outlet channel of the present invention is set above the water outlet of the first channel and the water outlet of the second channel, so that the first channel and the second channel are not adjacent to and staggered with the water outlet channel, and the water outlet of the first channel, the second channel The water outlet of the two channels and the water inlet of the water outlet channel are arranged in an upright triangle, so not only the wall thickness between the first channel, the second channel and the water outlet channel can be increased, but also the pipes between the first channel, the second channel and the water outlet channel can be increased path. Therefore, the wall thickness and pipe diameter of each channel can be increased at the same time.

Fourth, there is no need to install a pressurized motor to save costs (costs). The most common way to increase water pressure today is to install a pressurized motor, which additionally generates installation costs and maintenance costs (ie costs). The present invention completely does not need to install any electronic pressurizing devices (including those requiring power supply), which can save related expenses (costs). Therefore, there is no need to install a pressurized motor to save expenses (cost).

The above is only a detailed description of the present invention through preferred embodiments, and any simple modifications and changes made to the embodiments will not depart from the spirit and scope of the present invention.
