[0025] Reference Manual Attached Figure 1 To Attachment Figure 6 A convenient and adjustable temperature valve core comprises a housing 1, a temperature control knob 2, a switching assembly 3 and a central bolt 4. The housing 1 comprises a main body 11 and a waterway 12 arranged in an upper and lower manner. The main body 11 and the waterway 12 are both provided with sealing rings on their outer peripheries. The main body 11 is provided with at least one narrow slot 11a. Preferably, the number of the narrow slots 11a is two and the two are arranged oppositely. The waterway 12 is provided with a hot water inlet 121 and a cold water inlet 122. At the same time, a mixed water channel 123 is formed inside the waterway 12. A through hole 21 is provided in the middle of the temperature control knob 2. The side of the temperature control knob 2 has a first protrusion 22. The first protrusion 22 is snapped into the narrow slot 11a to cooperate with it, and can also control the rotation path of the temperature control knob 2. The thermostat 2 is preferably provided with a slot 11b at the top of the body 11, and the slot 11b is correspondingly arranged at the upper end of the slot 11a. The thermostat 2 is also provided with a second protrusion 23 that matches the slot 11b. The double cooperation between the protrusions and the slot or the slot 11b can not only reliably fix the thermostat 2 on the housing 1, but also the thermostat 2 can rotate around the housing 1 under the cooperation of the protrusion and the slot or the slot, and limit the rotation distance of the thermostat, so that the thermostat 2 can drive the center bolt to control the water inlet of hot water and adjust the water to a suitable water temperature. In addition, the bottom end of the thermostat 2 is also extended with a clamping portion 2b.

[0026] The switching assembly 3 includes a switching rod 31 and a switching disk 32. The switching rod 31 is arranged through the through hole 21 of the temperature control knob. The switching disk 32 is axially sleeved in the switching rod 31. A spring is arranged between the switching disk 32 and the switching rod 31. The switching assembly 3 adopts a ballpoint pen-type structure to control whether the valve core discharges water. Specifically, a plurality of spring teeth 31a (the spring teeth are serrated) are distributed circumferentially at the bottom of the switching rod 31 and a plurality of convex walls 31b are arranged on the circumferential side close to the spring teeth. The convex walls 31b limit the switching rod 31 on the temperature control knob 2. A plurality of ratchet teeth 32a cooperating with the spring teeth 31a are arranged circumferentially on the switching disk 32. When the switching rod 31 is pressed, the spring teeth 31a at the bottom of the switching rod cooperate with the ratchet teeth 32a on the switching disk, so that the switching disk can drive the center bolt 4 to move axially to control whether the valve core discharges water; at the same time, a limiting groove 32b is also arranged at the bottom of the switching disk 32, and the center bolt 4 is inserted into the limiting groove 32b.

[0027] See attached Figure 3 and attached Figure 4The center bolt 4 is located in the shell 1, and the center bolt 4 includes a joint portion 41, a disk body 42 and a piston portion 43. The joint portion 41 is located at the top of the center bolt 4, and the joint portion 41 is inserted into the limiting groove 32b of the switching disk; a card groove 42a is provided around the disk body 42, and the card groove 42a is engaged with the card groove 42b of the temperature adjustment knob, so that when the temperature adjustment knob 2 is rotated, the temperature adjustment knob can drive the center bolt 4 to rotate. Furthermore, a fixing plate 13 is also provided in the body 11 of the shell, and the fixing plate 13 is located at the bottom of the body 11. The fixing plate 13 cooperates with the body 11 to form a groove 13a, and a reset spring 5 is provided between the body 11 and the center bolt 4. , wherein one end of the reset spring 5 abuts against the groove body 13a, and the other end abuts against the center pin 4, the reset spring 5 cooperates with the disc body 42 of the center pin, and then the reset spring can drive the center pin to reset; the piston part 43 includes an upper piston part 43a and a lower piston part 43b, and the outer peripheries of the upper piston part 43a and the lower piston part 43b are both provided with grooves, and the upper sealing ring a and the lower sealing ring b are respectively sleeved in the grooves. Preferably, a plurality of ribs are also arranged at intervals in the waterway 12, and the ribs are located at the lower end of the lower piston part 43b, that is, the ribs are located between the lower piston part and the water outlet, and the ribs can prevent the lower sealing ring b from being washed out by water, thereby further ensuring the sealing performance. The upper piston part 43a is arranged in the body 11 and movably cooperates with one side of the fixed plate 13 in the body, that is, the upper piston part can move up and down along the fixed plate while maintaining the sealing of the two. The center plug 4 is provided with an adjustment wall 44 corresponding to the hot water inlet 121. For example, at least one adjustment wall 44 is extended from the bottom end of the upper piston part 43a of the center plug. Preferably, the number of the adjustment walls is two and the two are arranged opposite to each other, so that the flow rate can be ensured while the temperature can be quickly adjusted. Figure 5When the temperature adjustment knob 2 is rotated, the temperature adjustment knob 2 drives the center bolt 4 to rotate through its clamping part 2b, and then the adjustment wall 44 can control the hot water inlet 121 by blocking part or all of the hot water inlet 121, thereby controlling the final water outlet temperature; the lower piston part 43b is located at the bottom of the water channel 12 of the shell, and the lower piston part 43b selectively seals with the water channel 12 to control the water flow or water cutoff of the mixed water waterway 123. Preferably, the cross-sectional area of ​​the upper piston part 43a and the lower piston part 43b are equal, so that the water sealing cross-sectional area of ​​the valve core can be guaranteed to be the same. When switching to a high water pressure state, the pressing force will not increase with the increase of water pressure, and will not affect the user's pressing feel, so as to achieve normal function switching. Further, the area of ​​the upper sealing ring a of the piston part can be larger than the area of ​​the lower sealing ring b, so that the overall sealing of the valve core can be further guaranteed and the working performance can be improved. A convenient temperature-adjustable valve core of the present invention integrates both temperature adjustment and water discharge functions with a simple structure, realizing both functions on one valve core at the same time. The valve core is relatively small in size, which can not only greatly reduce the production cost, but also has a small pressing stroke for the valve core of this structure, and the flow rate is not affected by the pressing stroke, and the pressing feel is good, which can greatly improve the user experience.

[0028] The working process of the valve core will be described in detail below. Fig. 7A When the valve core is in the closed state, the lower piston portion 43b and the water channel 12 are sealed to block the mixed water channel 123. At this time, the valve core does not discharge water; refer to the attached Figure 7B When the switching rod 31 is pressed, the switching assembly will drive the center plug 4 to move downward. At this time, the lower piston part 43b of the center plug also moves downward, the mixed water channel 123 in the waterway 12 is opened, and the valve core starts to discharge water; when the temperature needs to be adjusted, the temperature adjustment knob 2 is rotated. At this time, the temperature adjustment knob 2 drives the center plug 4 to rotate, and the adjustment wall 44 on the center plug 4 also rotates accordingly, and then the water inlet 121 is controlled by the blocking degree of the adjustment wall 44 and the hot water inlet 121, so as to achieve the purpose of adjusting the outlet water temperature. In addition, the valve core of this structure only needs one temperature adjustment operation to achieve the original water temperature for each subsequent use, avoiding the tedious steps of frequent water temperature adjustment, simple operation, time-saving, and high comfort.
