Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the invention is further explained by combining the specific embodiments and the drawings.

As shown in fig. 1 to 3, the ceramic valve core of the faucet regulating valve convenient for temperature control comprises a valve core shell 1 and a valve core base 2, wherein the valve core shell 1 and the valve core base 2 are fixedly connected to form an accommodating space, and a handle 3, a rotary seat 4, a ceramic cover 5, a movable ceramic piece 6 and a static ceramic piece 7 are arranged in the accommodating space from top to bottom. The handle 3 is hinged with the rotary seat 4, the top end of the handle 3 extends out of the valve core shell 1, and the bottom end of the handle 3 is in linkage fit with the ceramic cover 5. The ceramic cover 5 is detachably and fixedly connected with the movable ceramic piece 6, the movable ceramic piece 6 is attached to the static ceramic piece and sealed through sealing oil, the static ceramic piece 7 is fixedly installed in the accommodating space, the static ceramic piece 7 and the valve core base 2 are respectively provided with a hot water inlet hole 21, a cold water inlet hole 22 and a water outlet hole 23, the lower end face of the static ceramic piece 7 is respectively provided with a hot water guide hole 71, a cold water guide hole 72 and a water outlet guide hole 73, and the upper end face of the static ceramic piece 7 is respectively provided with a hot water adjusting groove 711 and a cold water adjusting groove 722. The hot water inlet hole 21 is communicated with the hot water guide hole 71 and the hot water adjusting groove 711 to form a hot water inlet channel, the cold water inlet hole 22 is communicated with the cold water guide hole 72 and the cold water adjusting groove 722 to form a cold water inlet channel, the water outlet guide hole 73 penetrates through the whole static ceramic plate 7, and the water outlet guide hole 73 is communicated with the water outlet hole 23 to form a water outlet channel. The lower end surface of the movable ceramic plate 6 is provided with a water passing groove 61 which is always communicated with the water channel.

When in use, the handle 3 is rotated to rotate on the upper end surface of the static ceramic plate 7 through the water tank 61, so that the area ratio between the hot water adjusting tank 711 and the cold water adjusting tank 722 is changed, and the water outlet temperature of the water outlet guide hole 73 is further changed; when the handle 3 is pressed by a user, the water tank 61 is arranged on the upper end surface of the static ceramic plate 7

And slides back and forth, thereby changing the total area of the water passing groove 61 communicating with the hot water adjustment groove 711 and the cold water adjustment groove 722, and further changing the size of the discharged water from the discharged water guide hole 73.

Preferably, in order to make the structure of the present invention simpler and the manufacturing process more reasonable, the hot water adjusting groove 711 and the cold water adjusting groove 722 of the static ceramic plate 7 are both arc holes, but in order to make the hot water adjusting groove 711 and the cold water adjusting groove 722 have a certain angle of staggered parts and cannot interfere with each other, and also to ensure the compact structure, the radii of the arc holes of the hot water adjusting groove 711 and the cold water adjusting groove 722 should be different. The method specifically comprises the following steps: the angle of the staggered section is about 45 deg., and the handle 3 can be rotated through an angle of 90 deg..

The accuracy of the temperature control of the ceramic valve core of the faucet convenient for temperature control and the temperature control accuracy of the ceramic valve cores of other common faucets on the market are quantitatively analyzed.

Assuming that the hot water is at a constant temperature of 60 ℃, the water passing groove 61 of the moving ceramic plate 6 at a constant temperature of 20 ℃ for cold water occupies an angle of approximately 45 ℃ in the rotating work, and assuming that the temperature of the water outlet 23 is only related to the proportion of the cold water and the hot water in the angle occupied by the moving ceramic plate 6 and the temperature of the cold water and the hot water in order to simplify the outstanding characteristics of the model.

the accuracy of the three different configurations of the static ceramic plates 7 of fig. 4 to 6 with respect to the outlet water temperature control was analyzed in the context of the above assumptions.

For the shape of the circular hole static ceramic piece 8 shown on the left side of fig. 4, in order to meet the requirement that the rotation angle of the movable ceramic piece 6 is at least 45 degrees under two special conditions of only hot water outlet and only cold water outlet, when the initial position of the handle 3 is positioned in the middle and is adjusted towards the direction of hot water, the area occupied by the circular hole hot water adjusting groove 81 is rapidly increased, and the area occupied by the circular hole cold water adjusting groove 82 is rapidly decreased, so that the water outlet temperature of the circular hole water outlet guide hole 83 is rapidly cooled and heated when the proper water temperature is adjusted for bathing, the requirement of temperature control precision of daily face washing, bathing and the like of people is difficult to meet, and the specific function.

For the shape of the circular arc hole static ceramic plate 9 shown on the left side of fig. 5, the rotating angle of the movable ceramic plate 6 is at least 45 degrees in order to meet the special conditions of only hot water and only cold water. For the sake of calculation, we assume that the area ratio between the circular arc hole hot water regulation groove 91 and the circular arc hole cold water regulation groove 92 is its arc ratio. When the initial position of the faucet handle 3 is located at the hot water end and is adjusted towards the warm water direction, assuming that the rotated angle is a and a e [0 °,22.5 ° ], the water outlet temperature t of the circular arc hole water outlet guide hole 93 is 60 ℃x (45-a)/45+20 ℃xa/45 at this time, and a specific function image is shown on the right side of fig. 5. The function is a linear function, the slope k is 0.89, and the physical meaning of the function is that the water outlet temperature of the circular hole water outlet guide hole 93 is reduced by 0.89 ℃ when the handle 3 is turned from the circular hole hot water adjusting groove 91 to the circular hole cold water adjusting groove 92 every 1 DEG. The same analysis can obtain that the temperature of the outlet water of the arc hole outlet water guide hole 93 rises by 0.89 ℃ when the handle 3 rotates 1 degree from the arc hole cold water adjusting groove 92 to the arc hole hot water adjusting groove 91. The normal person adjusts the angular resolution of the handle 3 to about 5 deg., so that the temperature changes by 4.45 deg. per 5 deg. of rotation.

For the shape of the stationary ceramic plate 7 shown on the left in fig. 6, the angle of the cross section is about 45 °, and the angle of the moving ceramic plate 6 is at least 90 ° +45 ° -135 ° in order to satisfy the special case of only hot water and only cold water. For the sake of calculation, we also assume that the area ratio between the hot water adjustment tank 711 and the cold water adjustment tank 722 is its arc ratio. When the initial position of the handle 3 is located at the hot water end and is adjusted to the direction of the hot water, assuming that the rotated angle is a and a e [0 °,45 ° ], the outlet water temperature t of the outlet water guide hole 73 is 60℃ × 45/(45+ a) +20℃ × a/(45+ a), and the specific function image is shown on the right side of fig. 6. The slope of the function in the warm water area is very gentle, fine adjustment of the water temperature is very convenient during bathing, the theoretical calculation is that when the rotation angle is changed from 44 degrees to 45 degrees, the water temperature is changed from 40.22 degrees to 40.00 degrees, and the temperature change is only 0.22 degrees. The angle resolution of the normal people adjusting the faucet wrench is about 5 degrees, and then the water temperature is calculated to be changed from 41.18 ℃ to 40.00 ℃ when the rotating angle is changed from 40 degrees to 45 degrees, and the temperature is changed to be 1.18 ℃. In the same way, the initial position of the handle 3 can be analyzed to be positioned at the cold water end, and the temperature change is realized when the temperature is adjusted towards the warm water direction.

the comfortable temperature of people in summer is 37-40 ℃ and the comfortable temperature of people in winter is 39-42 ℃, so that the structure of the round hole static ceramic piece 8 and the circular arc hole static ceramic piece 9 is difficult to ensure the control precision of the temperature in bathing, the static ceramic piece 7 can easily reach the resolution of 1.18 ℃, and the regulation of the bathing temperature is very convenient and practical.

In conclusion, the structure of the static ceramic plate 7 is subversively optimized on the basis of not changing the appearance of the valve core of the existing water faucet, and the hot water adjusting groove 711 and the cold water adjusting groove 722 which are arranged on the upper end surface of the static ceramic plate 7 are changed into the staggered parts which are approximately in the asymmetric arrangement of arc holes and have certain angles. The optimization fundamentally solves the problem of low temperature adjustment precision of the ceramic valve core of the water tap, shortens the time of the temperature adjustment process, saves a large amount of water resources, has the same use method as that of the current mainstream water tap, and is convenient for users to accept.
