The temperature adjusting module 4 is arranged in the first pipe body 1 in the embodiment, so that the water outlet temperature of the water outlet 11 is automatically adjusted through the temperature adjusting module 4, and the user is prevented from being scalded due to overhigh temperature of hot water output from the water outlet 11.

The hot water enters the first pipe body 1 and is output through the water outlet 11, and the entering amount of the cold water in the third pipe body 3 is controlled by the temperature adjusting module 4.
Specifically, the water in the water tank is heated to a set temperature, and the temperature of the water for the user is lower than the temperature of the water in the water tank, so that after the hot water output from the water tank enters the first pipe body 1 through the second pipe body 2, the temperature adjusting module 4 can automatically adjust the mixing amount of the cold water of the third pipe body 3 according to the outlet water temperature of the water outlet of the first pipe body 1, and the first pipe body 1 outputs the water temperature required by the user.

In some embodiments, the shut-off valve 30 may be a manual valve, or the shut-off valve 30 may be an electrically controlled valve. Here, the specific representation entity of the stop valve 30 is not limited or described in detail.
In the second embodiment, as shown in fig. 3 to 9, a specific mechanical automatic temperature adjustment manner of the water mixing mechanism 20 is mainly realized by the temperature adjustment module 4, and the specific structure of the temperature adjustment module 4 includes: the temperature sensing device comprises a plunger 41, a sealing plug 42 and a temperature sensing driving part 43, wherein the plunger 41 is provided with a mounting hole 411 and at least one through hole 412, the through hole 412 is positioned at one side of the mounting hole 411, the temperature sensing driving part 43 comprises a cylinder body 431 and a push rod 432, the push rod 432 is inserted into the cylinder body 431, a temperature sensing cavity is formed between the push rod 432 and the inside of the cylinder body 431, the temperature sensing cavity is filled with a thermal expansion and contraction material (not shown), and the cylinder body 431 is arranged in the mounting hole 411; the sealing plug 42 is arranged on the mounting hole 12, the plunger 41 is slidably arranged in the first tube body 1, a cold water cavity is formed between the plunger 41 and the sealing plug 42 inside the first tube body 1, and the push rod 432 is arranged opposite to the sealing plug 42; the thermal expansion and cold contraction material is used for driving the push rod 432 to move by depending on the change of the outlet water temperature of the water outlet 11, and the push rod 432 is used for matching with the sealing plug 42 to drive the plunger 41 to slide so as to control the second water inlet 14 to be selectively communicated with the cold water cavity.
The specific working process of the temperature adjusting module 4 is as follows: when the outlet water temperature of the water outlet 11 is too high, the thermal expansion and contraction material in the cylinder 431 of the temperature-sensitive driving part 43 expands and makes the push rod 432 abut against the sealing plug 42. The push rod 432 uses the force generated by the thermal expansion and contraction material to push the cylinder 431 to drive the plunger 41 to move towards the water outlet 11, so that the second water inlet 14 arranged on the first pipe body 1 is communicated with the cold water cavity formed inside the first pipe body.
At this time, the cold water introduced by the third tube 3 enters the cold water chamber, and the cold water flows out through the through hole 412 and is mixed with the hot water flowing in from the first water inlet 13, so as to finally reduce the outlet water temperature of the water outlet 11, thereby preventing the user from being scalded.
And the temperature adjusting module 4 changes in volume according to the temperature change by means of the expansion and contraction material to control the push rod 432 to move, so that the second water inlet 14 is controlled to be selectively communicated with the cold water cavity.
In some embodiments, the choice of the expansion/contraction material may be made by using paraffin wax for temperature control in the conventional technology, for example, paraffin wax filling material in a paraffin wax temperature controller may be used, and the specific component ratio of the paraffin wax filling material is not limited herein.
In other embodiments, in order to achieve effective temperature control within a set temperature range, the push rod 432 of the temperature adjustment module 4 is arranged at a certain distance from the sealing plug 42 in an initial state, so as to achieve more accurate temperature control within a certain temperature range.
For example: when the temperature of the outlet water of the water outlet 11 is lower than the first set temperature T1, a gap is formed between the free end of the push rod 432 and the sealing plug 42; when the outlet water temperature of the water outlet 11 is higher than the second set temperature T2, the free end of the push rod 432 abuts against the sealing plug 42.
Specifically, the temperature value of T2 is greater than the temperature value of T1, and in the process of outputting hot water to the outside from the water outlet 11 of the first pipe body 1, when the water temperature is lower than T1, the push rod 432 is in a completely retracted state, and after the water temperature of the water outlet 11 is greater than T1, the push rod 432 gradually extends out relative to the cylinder 431 under the action of the thermal expansion and contraction material, and before the water temperature of the water outlet 11 does not reach T2, the plunger 41 is in an immovable state, so as to keep the second water inlet 14 disconnected from the cold water cavity. Therefore, the hot water can be ensured to be used by the user within the set temperature range, and further the phenomenon that the temperature of the water used by the user is too low due to the fact that cold water is added under the condition that the temperature of the hot water is not high is avoided.
In the practical application process, the values of T1 and T2 are not limited, and T2 is used as a trigger to mix cold water to avoid scalding the temperature trigger value of the user according to the temperature required by the hot water use requirement of the user under different conditions. For example: taking normal household as an example, the value of T1 can be 40 degrees, and the value of T2 can be 50 degrees; when the hot water entering the first pipe 1 is 50 degrees or less, the cold water in the third pipe 3 does not enter the first pipe 1. After the temperature of the water in the first pipe 1 exceeds 50 degrees, in order to prevent the hot water from scalding the user, the cold water delivered from the third pipe 3 enters the first pipe 1 and is mixed with the hot water, so as to reduce the temperature of the water output from the water outlet 11.
In another embodiment, in order to avoid the mutual influence of the water entering the second pipe 2 and the third pipe 3, the temperature regulating module 4 further comprises: and a seal ring 44, wherein the seal ring 44 is sleeved on the plunger 41 and is clamped between the plunger 41 and the inner pipe wall of the first pipe body 1, and the seal ring 44 is positioned between the first water inlet 13 and the second water inlet 14.
Specifically, after the plunger 41 is inserted into the first pipe 1, the sealing ring 44 is tightly attached to the inner wall of the first pipe 1, and the first water inlet 13 and the second water inlet 14 are separated by the sealing ring 44, so as to prevent hot and cold water entering from the first water inlet 13 and the second water inlet 14 from interfering with each other.
In some embodiments, the temperature adjustment module 4 further includes an elastic return member 45, and the elastic return member 45 is used for applying an elastic force to the plunger 41 or the cylinder 431 in a direction toward the sealing plug 42.
Specifically, when the temperature of water in the first pipe body 1 is high, the push rod 432 extends out and abuts against the sealing plug 42 to drive the plunger 41 to move, so that the second water inlet 14 is communicated with the cold water cavity. When the temperature of the water in the first pipe 1 is lowered, in order to avoid the temperature of the water discharged from the water outlet 11 being too low, the water path between the second water inlet 14 and the cold water chamber needs to be timely reduced or cut off. By configuring the elastic resetting member 45, when the push rod 432 retracts by using the elastic force exerted by the elastic resetting member 45, the elastic resetting member 45 can drive the plunger 41 to reset, thereby reducing or cutting off the water path between the second water inlet 14 and the cold water chamber.
In one embodiment, the elastic restoring member 45 may be a spring or a leaf spring. Taking a spring as an example, the spring is located in the first tube 1, one end of the spring abuts against the plunger 41 or the cylinder 431, and the other end of the spring abuts against the first tube 1. Taking the example of the spring abutting against the cylinder 431, the spring can apply a spring force to the cylinder 431, and the direction of the spring force is toward the sealing plug 42. When the temperature of the water outlet 11 is higher than T2 and hot and cold water mixing is required, the push rod 432 abuts against the sealing plug 42 to drive the cylinder 431 and the plunger 41 to move, thereby compressing the spring. And under the condition that the temperature of the water outlet 11 is lower than T2, the push rod 432 retracts, and the spring drives the cylinder 431 to drive the plunger 41 to move reversely and reset, so as to cut off the flow path between the second water inlet 14 and the cold water cavity.
In some embodiments, in order to facilitate the installation of the spring in the first pipe body 1, a position limiting plate 15 is provided inside the first pipe body 1 near the water outlet 11, and the other end of the spring abuts against the position limiting plate 15. Specifically, the stopper plate 15 can support the spring, so that the spring is pressed between the stopper plate 15 and the plunger 41 or the cylinder 431. Wherein, limiting plate 15 can be ring structure, can play good supporting role to the spring on the one hand, and on the other hand ring structure's limiting plate 15 can reduce stopping of rivers to ensure the smooth and easy play water of delivery port 11. In addition, a guide post 433 extending towards the water outlet 11 may be further disposed on the cylinder 431, the spring is sleeved on the guide post 433, and the guide post 433 can support and shape the spring, so that the posture of the spring is not inclined when the spring is compressed, and the assembling reliability is improved.
In a preferred embodiment, for example, to more reliably control the on-off of the flow path between the second water inlet 14 and the cold water chamber through the plunger 41, the sealing plug 42 is provided with a first retaining ring 421, one end surface of the plunger 41 is provided with a second retaining ring 413, and the second retaining ring 413 surrounds the outside of the through hole 412; after the first retaining ring 421 abuts against the second retaining ring 413, the edge of the first retaining ring 421 and the edge of the second retaining ring 413 cooperate with each other to form a sealing water blocking surface.
Specifically, when the flow path between the second water inlet 14 and the cold water cavity needs to be cut off, after the first retaining ring 421 abuts against the second retaining ring 413, a connection portion formed between the first retaining ring 421 and the second retaining ring 413 forms a sealed water blocking surface, so as to cut off the flow path between the second water inlet 14 and the cold water cavity. When the cold water and the hot water entering through the second water inlet 14 are required to be mixed, the plunger 41 moves to make the second retainer ring 413 far away from the first retainer ring 421, so that the flow path between the second water inlet 14 and the cold water cavity is conducted.
Similarly, for better anti-scald purpose, in an embodiment, a step surface 16 may be further disposed in the first pipe body 1, and the step surface 16 is located between the water outlet 11 and the first water inlet 13; one end face of the plunger 41 is provided with a third retaining ring, and a flowing water interval is formed between the third retaining ring and the step face 16. Specifically, when hot and cold water needs to be mixed, the plunger 41 moves towards the water outlet 11, so that the distance between the third retainer and the step surface 16 is reduced, the hot water outflow is reduced, and the water temperature can be adjusted more quickly and efficiently to meet the anti-scalding requirement.
In some embodiments, a positioning plate 422 is further disposed on the sealing plug 42, and the positioning plate 422 can cooperate with the push rod 432 to exert a reverse thrust on the push rod 432.
In the third embodiment, as shown in fig. 8, based on the first and second embodiments, in order to facilitate the user or the operator to adjust the temperature of the triggered mixed water, a screw 423 is threadedly connected to the sealing plug 42, one end of the screw 423 is connected to the positioning plate 422, and the other end of the screw 423 extends to the outside of the sealing plug 42. When the temperature of the trigger mixed water needs to be adjusted, the screw 423 is rotated to adjust the distance between the positioning plate 422 and the push rod 432 in the retraction state, so that the temperature of the trigger mixed water can be adjusted.
