In addition, the terms "first" and "second" are only used for differentiation in description and have no special meaning.
[0040] Such as Figures 1 to 7As shown in the figure, the present utility model provides a pressure stabilizing valve assembly. The pressure stabilizing valve assembly 10 includes a valve body 1, a valve core 2, and an elastic member 4. The valve body 1 is provided with a through cavity; at least a part of the valve core 2 is movably arranged in the through cavity. The valve core 2 has a first state and a second state that can be switched with each other. A through first hole 21 is formed in the valve core 2; a gap 7 is provided between the valve core 2 and the valve body 1, and a sealing member 3 is provided around the valve core 2; the elastic member 4 is arranged in the through cavity, one end of the elastic member 4 is connected to the valve body 1, and the other end of the elastic member 4 is connected to the valve core 2; in the first state, the valve core 2 compresses the elastic member 4, and the sealing member 3 seals the gap 7; in the second state, the sealing member 3 opens the gap 7; the elastic member 4 has a tendency to keep the valve core 2 in the second state.
[0041] With the above structure, as Figure 2 and Figure 3 shown, when the pressure received by the valve core 2 increases, the valve core 2 compresses the elastic member 4, and the elastic member 4 stores energy; and the gap 7 between the valve core 2 and the valve body 1 is sealed by the sealing member 3. At this time, the communication at both ends of the pressure stabilizing valve assembly 10 is realized by the first hole 21 on the valve core 2; when the pressure received by the valve core 2 decreases, the valve core 2 is subjected to the restoring force of the elastic member 4 and changes from the first state to the second state. When in the second state, the sealing member 3 opens the gap 7. At this time, the communication at both ends of the pressure stabilizing valve assembly 10 is jointly completed by the first hole 21 on the valve core 2 and the gap 7 between the valve core 2 and the valve body 1. Furthermore, the water output can be automatically adjusted according to the water pressure, ensuring a large water output at low pressure and stabilizing the water output flow within a certain range at high pressure, thereby improving comfort.
[0042] In some embodiments, as Figures 2 to 5 shown, in order to provide an installation position for the elastic member 4, the valve body 1 is provided with a support seat 11. The support seat 11 is located in the through cavity, and the elastic member 4 is placed on the support seat 11; of course, in order to prevent the support seat 11 from closing the above-mentioned through cavity, the support seat 11 is provided with a plurality of second holes 12. Exemplarily, the elastic member 4 can but is not limited to a spring. In the current embodiment, the elastic member 4 is a spring, and the spring has better strength and corrosion resistance. Further, in order to better install the above spring, mounting protrusions 6 are provided on the surfaces of the support seat 11 opposite to the valve core 2, and the spring is sleeved on the above mounting protrusions 6.
[0043] Furthermore, since there is a gap 7 between the valve core 2 and the valve body 1, when the valve core 2 moves in the through cavity, in order to maintain the stability of the movement of the valve core 2, the support seat 11 is also provided with a guide hole 13. The guide hole 13 is in the same direction as the through cavity, and a guide shaft 22 is provided on the side of the valve core 2 facing the support seat 11. In the current embodiment, the guide hole 13 is opened on the mounting protrusion 6 of the support seat 11, and a mounting groove is opened on the mounting protrusion 6 of the valve core 2. The guide shaft 22 is installed at the bottom of the mounting groove, that is, the spring is sleeved outside the two mounting protrusions 6. The guide shaft 22 is located inside the spring and is movably inserted into the guide hole 13, so as to ensure the stability of the movement.
[0044] In some embodiments, the valve body 1 is further provided with a plurality of limiting protrusions 14. The plurality of limiting protrusions 14 are circumferentially spaced on the inner wall of the through cavity. The limiting protrusions 14 are arranged above the support seat 11. When the valve core 2 compresses the elastic member 4, that is, when the valve core 2 transitions from the second state to the first state, the valve core 2 can abut against the above-mentioned limiting protrusions 14 to prevent it from moving excessively. Further, in order to make the contact between the valve core 2 and the limiting protrusions 14 stable, inclined surfaces that cooperate with each other in abutment are provided on the sides of the limiting protrusions 14 and the valve core 2 facing each other. Through the contact of the two inclined surfaces, the contact area between the two is increased.
[0045] In some embodiments, as Figures 4 to 6 shown, when the valve core 2 transitions from the first state to the second state by the restoring force of the elastic member 4, in order to prevent the valve core 2 from detaching, the valve core 2 is further provided with a limiting strip 23. The limiting strip 23 corresponds to the limiting protrusion 14 one by one. The first end of the limiting strip 23 is connected to the side of the valve core 2 facing the elastic member 4, and the second end extends in a direction away from the valve core 22, that is, the limiting strip 23 is strip-shaped; and a clamping protrusion 24 is provided at the second end of the limiting strip 23. The clamping protrusion 24 protrudes from the limiting strip 23. Thus, when the valve core 2 is subjected to the restoring force of the elastic member 4, the clamping protrusion 24 can abut against the lower side of the limiting protrusion 14, and thus can be limited by the limiting protrusion 14 to limit the valve core 2 from detaching from the valve body 1. Further, in order to avoid unnecessary interference, the second holes 12 on the support seat 11 are provided corresponding to the limiting strips 23 one by one, and the aperture of the second holes 12 can allow the limiting strips 23 and the clamping protrusions 24 to pass through; it should be noted that the second holes 12 with a larger aperture are also more convenient for liquid passage.
[0046] In some embodiments, as Figure 2 、 Figure 3 and Figure 7As shown in the figure, on the side of the valve core 2 facing away from the elastic member 4, there is an annular groove 26. A plurality of the first holes 21 are opened at the bottom of the annular groove 26. A flow limiting ring 5 is also embedded in the annular groove 26. It can be understood that in order not to block the first holes 21, the size of the flow limiting ring 5 is smaller than that of the annular groove 26. In the current embodiment, the flow limiting ring 5 is an O-ring. Thus, when water flow needs to pass through the first holes 21, it will hit the flow limiting ring 5, thereby squeezing the flow limiting ring 5, increasing the diameter of the flow limiting ring 5, partially blocking the first holes 21, and thus restricting the flow rate.
[0047] In some embodiments, as Figures 4 to 7 shown, a circumferential placement groove 25 is formed on the outer periphery of the valve core 2, and the seal 3 is arranged in the placement groove 25. In the current embodiment, the seal 3 is a sealing ring. The upper wall of the placement groove 25 protrudes from the lower wall of the placement groove 25, that is, the outer diameter of the upper wall of the placement groove 25 is larger than the outer diameter of the lower wall of the placement groove 25; in addition, the outer diameter of the lower wall of the placement groove 25 is smaller than the inner diameter of the through cavity, so that a gap 7 is formed between the valve core 2 and the valve body 1, so that the lower wall of the placement groove 25 can be placed in the through cavity; and the outer diameter of the upper wall of the placement groove 25 is larger than the inner diameter of the through cavity. Thus, when the pressure received by the valve core 2 is less than the elastic force of the elastic member 4, the valve core 2 is in the second state, the seal 3 is above the valve body 1, and there is a gap 7 between the lower wall of the placement groove 25 and the inner wall of the through cavity, so that water can flow through; when the pressure received by the valve core 2 is greater than the elastic force of the elastic member 4, when the valve core 2 moves downward, the lower wall of the placement groove 25 is located in the through cavity, and the upper wall of the placement groove 25 will jointly clamp the seal 3 with the valve body 1, thereby sealing the gap 7 between the valve core 2 and the valve body 1. There is a gap 7 between the lower wall of the placement groove 25 and the inner diameter of the through cavity and water cannot flow through, and only the first holes 21 on the valve core 2 can be used for water flow through.
[0048] As Figure 8 shown, the present invention also provides a water outlet mechanism, which includes a water outlet head 20, a water pipe 30, and the above-mentioned pressure stabilizing valve assembly 10; the water pipe 30 is connected to the water outlet head 20, and the pressure stabilizing valve assembly 10 is arranged in the water pipe 30 or the inlet of the water outlet head 20. Thus, when the water pressure in the water pipe 30 increases, when the pressure increases, the valve core 2 compresses the elastic member 4, and the elastic member 4 stores energy; and the gap 7 between the valve core 2 and the valve body 1 is closed by the seal 3, and the water flow passes through the first holes 21 on the valve core 2; when the pressure received by the valve core 2 decreases, the seal 3 opens the gap 7, and the water flow passes through the first holes 21 on the valve core 2 and the gap 7 between the valve core 2 and the valve body 1 together, so that the water output can be automatically adjusted according to the water pressure, and a large amount of water can be ensured at low pressure, and the water output flow rate can be stabilized within a certain range at high pressure. Exemplarily, the water outlet head 20 can be but is not limited to a shower head, a faucet, etc.
[0049] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here.
