Description

Technical Field

[0001] The invention relates to the technical field of water-using sanitary ware, and in particular to an adaptive water-saving faucet. Background Art

[0002] Traditional faucets are simple in design and lack effective water-saving mechanisms, which leads to a waste of water resources. For example, old-fashioned spiral faucets are not tightly closed, have insensitive induction, close slowly, and have little water-saving effect. In addition, the water supply pressure of most faucets causes the flow rate to increase under high water pressure even if they are designed to save water. There is a serious overpressure outflow phenomenon, and a large amount of water is lost in vain. At the same time, traditional faucets have a single water outlet mode and cannot adjust the water outlet mode according to the usage scenario, resulting in a comfortable user experience in situations where a gentle water flow is required (such as washing hands and vegetables). In addition, the design of the water outlet often ignores the dynamic characteristics of the water flow, resulting in the water flow impact being too large or too small, affecting the use effect. Summary of the invention

[0003] The main purpose of the present invention is to solve the technical problems described in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides an adaptive water-saving faucet, which includes a shell, the shell includes a water inlet and a water outlet, and the shell is provided with a first pressure cover, a spring sheet, a second pressure cover, a sphere and a filter screen in sequence from the water inlet to the water outlet, the first pressure cover and the second pressure cover are provided with a central through hole, and the side of the second pressure cover in contact with the spring sheet is provided with a groove for placing the spring sheet, and the sphere is suspended and fixed in the shell.

[0032] The present invention provides an adaptive water-saving faucet, referring to Figure 1-9 In one embodiment, the adaptive water-saving faucet includes a shell 1, the shell 1 includes a water inlet and a water outlet, and the shell 1 is provided with a first gland 2, a spring 3, a second gland 4, a sphere 5 and a filter 6 in sequence from the water inlet to the water outlet, the first gland 2 and the second gland 4 are provided with a central through hole 7, and the side of the second gland 4 in contact with the spring 3 is provided with a groove for placing the spring 3, and the sphere 5 is suspended and fixed in the shell 1.

[0033] Among them, the spring sheet 3 is a metal sheet, which can deform to different degrees when subjected to water with different water pressures to control the water output; the sphere 5 is suspended and fixed, which means that the sphere 5 is kept at a distance from the upper component (the second pressure cover 4) and the lower component (the filter 6), and the sphere 5 cannot move.

[0034] Specifically, water flows into the adaptive water-saving faucet S from the water inlet, and flows through the first gland 2, the spring 3, the second gland 4, the ball 5 and the filter 6 in sequence.

[0035] In this embodiment, by setting a spring piece 3, a fixed sphere 5 and a filter 6 in the adaptive water-saving faucet, the spring piece 3 can automatically adjust the water volume according to the water pressure and usage conditions to achieve the effect of water saving. The fixed sphere 5 can make the water flow more stably when passing through the sphere 5, and the filter 6 can make the water flow out of the faucet more uniform, thereby amplifying the effect of the water flow and saving water resources.

[0036] In the prior art, the solution is to only suspend the sphere. The present application, on the one hand, adds a leakage net to make the water flow more uniform, further enhancing the water outlet effect. On the other hand, a suspended and fixed sphere 5 is provided. The sphere 5 is suspended and fixed in the adaptive water-saving faucet by a sphere fixing ring 51 with a serrated outer ring, and the length of the sphere fixing ring 51 is shortened, which enhances the water outlet effect, increases the total water outlet area, and plays a role in guiding flow, ensuring the stability of the water flow direction when the water pressure changes and the atomization is uneven. At the same time, the present application simplifies the parts and components, and sets the adaptive water-saving faucet into a segmented structure, which is easy to disassemble and has a lower cost than the technical solutions of the prior art.

[0037] In one embodiment, referring to Figure 1 and Figure 2 The ball 5 is fixed in the housing 1 by a ball fixing ring 51, and the outer ring of the ball fixing ring 51 is serrated.

[0038] The cross-sectional area of ​​the sphere 5 can be substantially equal to the maximum area of ​​water ejected from the second gland 4 (or the first cylinder 11); the sphere 5 can be connected and fixed to the sphere fixing ring 51 through a connecting column, and the sphere fixing ring 51 is connected to the sphere 5 through at least one connecting column, such as Figure 6 Shown are 3 connection posts.

[0039] In this embodiment, the outer ring of the ball fixing ring 51 is serrated to improve the water outlet effect, increase the total water outlet area and play a role in diversion. The ball 5 will not contact other parts due to water pressure, thereby reducing the water outlet effect.

[0040] In one embodiment, referring to Figure 1-4 The housing 1 includes a first cylinder 11 and a second cylinder 12 that are detachably connected, the first pressure cover 2, the spring 3 and the second pressure cover 4 are arranged in the first cylinder 11, and the ball 5 and the filter 6 are arranged in the second cylinder 12.

[0041] In this embodiment, a vent hole / ventilation gap is provided between the first cylinder 11 and the second cylinder 12. In other embodiments, the first cylinder 11 and the second cylinder 12 are not connected in a closed manner.

[0042] In this embodiment, by providing the first cylinder 11 and the second cylinder 12, the faucet is easy to disassemble and repair, and when problems such as blockage occur inside the faucet, they can be handled conveniently and quickly.

[0043] In one embodiment, referring to Figure 1-4A connecting portion 111 is provided at one end of the first cylinder 11 close to the second cylinder 12, and an external thread is provided on the connecting portion 111. An internal thread matching the external thread is provided at one end of the second cylinder 12.

[0044] In this embodiment, there is a gap between the connecting portion 111 and the first cylinder 11. In other embodiments, the connecting portion 111 can be directly provided on the first cylinder 11 (ie, an end of the first cylinder 11 close to the second cylinder 12 is provided with an external thread).

[0045] In this embodiment, a connecting portion 111 is provided to connect the first cylinder 11 with the second cylinder 12, so that the faucet can be easily disassembled and air can flow in at the same time without specially designing a vent hole. In addition, the first pressure cap 2, the spring 3 and the second pressure cap 4 are arranged in the first cylinder 11, so that the first cylinder 11 has the function of adjusting the water volume according to the water pressure and usage conditions. The ball 5 and the filter 6 are arranged in the second cylinder 12 so that the second cylinder 12 has the effect of amplifying the water output and uniformly outputting water. When the faucet fails or parts need to be replaced, the first cylinder 11 and the second cylinder 12 of the faucet can be targetedly processed according to the failure condition or the required replacement parts. The use of the faucet is more convenient and the use time of the faucet is extended, and there is no need to replace the entire faucet due to partial failure.

[0046] In one embodiment, referring to Figure 1-4 The connecting portion 111 is provided with an external thread, and the second cylinder 12 is provided with an internal thread matching the external thread.

[0047] In this embodiment, the first cylinder 11 and the second cylinder 12 are connected by a thread (detachable), so that the installation and maintenance of the faucet are more convenient.

[0048] In one embodiment, referring to Figure 1 and 3 The filter screen 6 is provided with a filter screen fixing ring 61 , and the filter screen 6 is fixed to the housing 1 through the filter screen fixing ring 61 .

[0049] The filter screen 6 may also be directly installed / fixed on the bottom of the second cylinder 12 .

[0050] In this embodiment, the filter 6 is stably fixed on the outer shell 1 by setting a filter fixing ring 61, and is not easy to fall off; in other embodiments, the filter 6 can also be directly installed on the bottom of the second cylinder 12, or the filter 6 and the second cylinder 12 can be formed integrally.

[0051] In one embodiment, referring to Figure 3 and Fig. 9The ball 5 is suspended and fixed in the filter fixing ring 61 by the ball fixing ring 51 .

[0052] Among them, you can refer to Figure 6 , Figure 7 and Fig. 9 The filter fixing ring 61 includes an upper part and a lower part, and the upper part and the lower part are connected by a connecting rib. The inner diameter formed by the connecting rib is smaller than the outer diameter of the ball fixing ring 51, which provides support for the ball fixing ring 51 so that the ball fixing ring 51 is fixed to the upper part. The height of the ball fixing ring 51 is equal to the height of the upper part. The center points of the sphere 5 and the sphere fixing ring 51 are located on the same plane, that is, the sphere 5 is at a certain distance from the lower end of the first cylinder 11 and the filter 6. At the same time, the outer ring of the sphere fixing ring 51 is serrated, and the sphere fixing ring 51 and the upper part are clamped with each other, so that the filter fixing ring 61 (filter 6) is not easy to fall off from the second cylinder 12; in another embodiment, a retaining ring is provided at one end of the upper part close to the water outlet, and the retaining ring is installed in the internal thread of the second cylinder 12, so that the filter 6 is fixed in the second cylinder 12.

[0053] In this embodiment, the ball fixing ring 51 is provided to fix the ball 5 relative to the faucet, and the ball 5 will not be displaced due to the magnitude of the water pressure, resulting in unstable water flow.

[0054] In one embodiment, referring to Figure 1-3 and Figure 5 The second gland 4 includes a first part 41 and a second part 42 , the first part 41 is embedded in the lower end of the first gland 2 , the outer diameter of the first part 41 is smaller than the outer diameter of the second part 42 , and the groove is set on the first part 41 .

[0055] The spring piece 3 is a stainless steel spring piece 3 . The spring piece 3 used in the faucet has a small area and is deformed toward the central circular hole of the second part 42 under the impact of the water flow, thereby allowing the water flow to pass through.

[0056] In this embodiment, the outer diameter of the second part 42 is larger than the outer diameter of the first part 41. The first part 41 is embedded in the first pressure cover 2 so that the groove forms a sealed space, and throttling is started. After the first pressure cover 2 is pressed on the second pressure cover 4, the stainless steel spring 3 is located at the center of the second part 42, and the flow of water passing through will be reduced due to pressure.

[0057] In one embodiment, referring to Figure 1-2 The outer diameters of the spring piece 3 and the first part 41 are equal, the groove matches the shape of the spring piece 3, and a notch is provided on the groove.

[0058] In this embodiment, the notch is provided to prevent water from being completely blocked from passing through the central through hole 7 of the first truncated cone due to the blockage of the spring sheet 3. Due to the characteristics of water, water can still pass through the gap between the central through hole 7 and the spring sheet 3 in the notch, so that when the water pressure is too low to deform the stainless steel sheet, the water can pass through the stainless steel spring sheet 3 and the notch, thereby ensuring that there is enough water flowing through.

[0059] In one embodiment, referring to Figure 5 , notches are arranged on both sides of the groove, and the notches are semicircular.

[0060] The notch area needs to be larger than the diameter of the first end of the second gland 4.

[0061] In this embodiment, by setting the shape of the notch, the spring piece 3 ensures that the water flow area automatically adapts to the water flow pressure under the impact pressure of the water flow, that is, the flow area is small when the water pressure is high and the flow area is large when the water pressure is low, so that the final water flow rate remains basically consistent.

[0062] In one embodiment, the height of the spring piece 3 is equal to the height of the groove, and the length of the spring piece 3 is equal to the diameter of the first part 41. The width of the spring piece 3 can be adjusted as needed (the relationship between the width of the spring piece 3 and the diameter of the first end of the second cylinder 12 is adjusted) to control the water outflow rate, thereby being able to target different water use conditions.

[0063] In this embodiment, the width of the spring piece 3 is greater than the diameter of the circular water flow holes of the upper and lower glands (the first gland 2 and the second gland 4).

[0064] In one embodiment, the central through hole 7 of the second gland 4 includes a first end close to the water inlet and a second end close to the water outlet, and the diameter of the first end is smaller than the diameter of the second end.

[0065] The central through hole 7 of the second gland 4 is an inverted cone / truncated cone (see Figure 3 ), on the one hand, it can guide the water flow into a reasonable direction, and on the other hand, it is convenient for the water flow rate to be the same after the spring piece 3 is impacted by the water pressure.

[0066] In one embodiment, a retaining ring is provided at one end of the first cylinder 11 close to the second cylinder 12. Figure 4 The retaining ring confines the components in the first cylinder 11 in the first cylinder 11 , and the outer diameter of the retaining ring is equal to the outer diameter of the first cylinder 11 and the inner diameter is greater than the diameter of the second end of the second gland 4 .

[0067] In the case where the connecting portion 111 is provided, a retaining ring is provided at one end of the first cylinder 11 close to the second cylinder 4 , and a retaining ring is also provided inside the connecting portion 111 .

[0068] In this embodiment, the inner diameter of the retaining ring is larger than the diameter of the second end of the second gland 4, so that the pressure on the water flow when passing through this place is reduced, the area for water outflow is increased, and the water outlet effect is enhanced.

[0069] In one embodiment, referring to Figure 8 , the filter screen 6 is a spider web filter screen 6.

[0070] In this embodiment, the use of the spider web-type filter 6 can efficiently filter water, improve the cleanliness of the water, and make the water flow out of the water outlet more evenly.

[0071] In one embodiment, referring to Figure 1-3 An internal thread is provided at one end of the first cylinder 11 close to the water outlet, and the internal thread is used to install the adaptive water-saving faucet on an external water pipe.

[0072] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
