Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom technology, in particular to a water outlet buffering structure and a water outlet device. BACKGROUND

[0002] At present, there are various types of water outlet devices in the prior art, including faucets, shower heads, spray guns, etc. The water outlet device often uses a control valve to control the opening and closing of the waterway. Some control valves are electrically controlled, and some are purely mechanical. Taking an induction faucet as an example, the induction faucet generally uses a solenoid valve as a water opening and closing control device, and combines infrared induction or laser induction to control whether the solenoid valve is powered on or not, thereby achieving the function of an induction switch. In the induction faucet, a water outlet pipe is usually connected between the water outlet end of the electric control valve (i.e. the solenoid valve) and the bubbler of the water outlet nozzle. When the solenoid valve of the induction faucet is instantaneously opened or closed, the water pressure in the water outlet pipe will instantaneously rise and fall. The greater the water inlet pressure of the induction faucet, the greater the instantaneous rise and fall of the water pressure in the water outlet pipe. The water outlet pipe is usually made of metal or plastic, which has a relatively high hardness and cannot be elastically deformed. When the water pressure instantaneously rises, the water will impact the inner wall of the water outlet pipe. Therefore, the existing induction faucet often produces different degrees of water impact sound when the induction switch is turned on, which is commonly known as water noise (similar to the sound of sea waves hitting the shore). The water noise occurs simultaneously with each induction switch, and the sound is loud, which seriously affects the user's experience. Some public washrooms have a serious water noise echo problem. The instantaneous rise and fall of the water pressure in the water outlet pipe also causes serious impact damage to the solenoid valve, the bubbler and other accessories, thereby seriously affecting the service life of the induction faucet, which is the main reason why the service life of the induction faucet is shorter than that of the conventional mechanical faucet. In addition, the instantaneous change in water pressure in the water outlet pipe also causes the connection between the two ends of the water outlet pipe to easily leak and seep, which seriously affects the quality stability and reputation of the induction faucet. Moreover, due to the instantaneous rise in water pressure, the water outlet flow rate will first increase and then decrease slowly, resulting in unstable water outlet flow rate (the water outlet flow rate changes rapidly, and the water pressure in the pipe rises rapidly). When the faucet uses a purely mechanical control valve and is operated quickly, the above problems will also occur. In addition to faucets, other water outlet devices that use electrically controlled control valves or mechanically controlled control valves will also have the above problems if they are operated quickly.

[0034] Please see Figures 1-9 As shown, a water outlet buffer structure of the present invention includes a support body, and,

[0035] The flexible hose has an inlet end and an outlet end. The flexible hose is housed within the support body and has one or more buffer sections. These buffer sections are bent into a predetermined shape within the support body, forming one or more corners. Each corner is a point of elastic deformation for the flexible hose. "Multiple" refers to two or more.

[0036] In this embodiment, the support body is provided with a positioning guide groove 111 whose shape is adapted to the buffer section 51. The buffer section 51 is installed in the positioning guide groove 111, and the positioning guide groove 111 and the outer side of each corner of the buffer section 51 are respectively provided with clearance notches 112, such as... Figure 7 As shown, this allows the flexible hose 5 to elastically deform outwards at each corner. The depth of the positioning guide groove 111 is greater than or equal to half the outer diameter of the flexible hose 5, ensuring that the buffer section 51 of the flexible hose 5 can be fixed along the shape of the positioning guide groove 111. The width of the positioning guide groove 111 is the same as or substantially the same as the outer diameter of the flexible hose 5. The positioning guide groove 111 and its clearance notch 112 ensure effective positioning of the buffer section 51 of the flexible hose 5, while not hindering the elastic deformation of the flexible hose 5 at its elastic deformation point.

[0037] In this embodiment, the buffer segment 51 is S-shaped, and each corner is rounded. The buffer segment 51 roughly forms three corners 511, 512, and 513, as shown below. Figure 5 As shown. Therefore, the positioning guide groove 111 is also S-shaped, and the positioning guide groove 111 is provided with three clearance notches 112. These three clearance notches 112 are distributed sequentially along the length direction of the buffer section 51 and correspond one-to-one with the three corners 511, 512, and 513 of the buffer section 51. The number of clearance notches 112 and corners is not limited to three. The S-shaped shape of the buffer section 51 simplifies the shape design of the buffer section 51 and achieves the purpose of multiple corners and multiple absorption points. On the other hand, it ensures that the corners are rounded, thereby ensuring that the radial cross-sectional area of ​​each position of the elastic hose 5 is not large and will not affect the water flow area. In other embodiments, the buffer section is W-shaped or other curved shape with corners.

[0038] In this embodiment, the Shore hardness of the flexible hose 5 is 40° to 75°; the wall thickness of the flexible hose 5 is 1 to 2.5 mm, ensuring that the hose will not break due to high water pressure, while maintaining its elasticity.

[0039] Specifically, the elastic hose 5 is a silicone tube or a rubber tube, etc., which has good elastic deformation ability. Combined with the positioning guide groove 111, it restricts the buffer section 51 of the elastic hose 5, which satisfies the fixed shape and restricts the elastic expansion space, leaving only the corners as buffer points to absorb pressure. This absorption and buffering effect is optimal.

[0040] In this embodiment, the support body is provided with a water inlet and / or a water outlet. The water inlet is connected to the water inlet end of the elastic hose, and the water outlet is connected to the water outlet end of the elastic hose. The support body is the device body of a water outlet device or a water outlet pipe, etc. Specifically, the water outlet device is a faucet; therefore, the device body is the faucet body 1, and the elastic hose constitutes the water outlet pipe of the faucet.

[0041] In the water outlet buffer structure of this invention, during application, when the water pressure in the elastic hose 5 rises instantaneously, the instantaneously rising water pressure will successively expand the elastic hose 5 outward at the three corners of the buffer section 51, forming protrusions 514, 515, and 516. The deformation of protrusion 514 at the first corner 511 is the largest, the deformation of protrusion 516 at the third corner 513 is the smallest, and the deformation of protrusion 515 at the second corner 512 is in the middle. Figure 9 As shown. Therefore, the elastic hose 5 resists the instantaneous rise in water pressure through elastic deformation, which is equivalent to releasing and absorbing the impact force brought by the instantaneous pressure increase, thereby eliminating water noise, solving the problem of unstable water flow from large to small, ensuring that the water flow is constant, and solving the problem of water pressure impacting the control valve, aerator, etc. of the water outlet device, causing short service life and leakage and seepage, thus greatly improving the service life of the water outlet device.

[0042] Please see Figures 1-9 As shown, a water outlet device of the present invention includes a device body, the device body having a water outlet portion, and a water outlet buffer structure as described above. The device body constitutes the support body, or the support body is disposed within the device body, and the water outlet portion is connected to the water outlet end of the elastic hose. In this embodiment, the water outlet device of the present invention is a faucet; therefore, the device body is the faucet body 1. In other embodiments, the water outlet device is a shower head, and the device body is the shower head body; or, the water outlet device is a spray gun, and the device body is the spray gun body. The faucet body 1 constitutes the support body, but is not limited thereto. In other embodiments, the support body and the device body (i.e., the faucet body 1) are separate from each other, and the support body is disposed within the faucet body 1.

[0043] In this embodiment, the water outlet device of the present invention further includes a control valve, which is disposed on the device body (i.e., faucet body 1) and is used to control whether water is discharged from the elastic hose; the water inlet end of the elastic hose is connected to the water outlet end of the control valve. The control valve is electrically controlled and is a solenoid valve 21, but is not limited thereto. In other embodiments, the control valve is a mechanical control valve, etc.

[0044] In this embodiment, the water outlet device of the present invention further includes a temperature regulating valve core 22. The outlet end of the temperature regulating valve core 22 is connected to the inlet end of the control valve (i.e., solenoid valve 21). The inlet end of the temperature regulating valve core 22 is connected to an inlet section 3, which includes a cold water inlet pipe 31 and a hot water inlet pipe 32. The control valve (i.e., solenoid valve 21) and the temperature regulating valve core 22 are integrated together to form a control valve assembly 2. The valve stem 221 of the temperature regulating valve core 22 is connected to a temperature regulating handle 222, which is located outside the faucet body 1. The temperature regulating handle 222 can be replaced by a temperature regulating handwheel. In other embodiments, the water outlet device of the present invention does not include a temperature regulating valve core. The inlet end of the control valve is connected to an inlet section, which is a single inlet type. Therefore, the inlet section includes one inlet pipe.

[0045] In this embodiment, the two ends of the flexible hose 5 are respectively connected to the water outlet and the control valve (i.e., the solenoid valve 21) by flexible clamps 6. The flexible clamps 6 can also be called spring steel clamps, etc., and their structure is as follows: Figure 6 As shown, the elastic clamp 6 includes an annular body 61 and two legs 62 extending from both ends of the annular body 61 and intersecting each other. When the two legs 62 are pressed and brought together, the inner diameter of the annular body 61 increases, making it easier to pass through the elastic hose 5. When the two legs 62 are released, the annular body 61 returns to its original position, making its inner diameter smaller than that of the elastic hose 5, thereby tightening the elastic hose 5.

[0046] In this embodiment, the faucet body 1 is provided with a sensing window (not shown in the figure) for sensing a human hand to control whether the solenoid valve 21 is opened or closed. A power supply battery 7 is fixed inside the device body 1 by a battery clip 71, and the power supply battery 7 supplies power to the solenoid valve 21.

[0047] In this embodiment, the faucet body 1 includes a valve body 11 and a panel 12. The valve body 11 is inverted L-shaped, with its vertical portion extending vertically and housing the control valve 2. The upper end of the horizontal portion of the valve body 11 is open, and the buffer section 51 of the flexible hose 5 is located within the horizontal portion of the valve body 11. Therefore, the horizontal portion of the valve body 11 is provided with the positioning guide groove 111. The water outlet 4 is located at the end of the horizontal portion of the valve body 11 away from the vertical portion. The panel 12 is snap-fitted to the upper open portion of the valve body 11 and covers the upper opening of the vertical portion. The water outlet 4 specifically includes a water outlet connector 41 and an aerator 42 located at the water outlet end of the water outlet connector 41. The water inlet end of the water outlet connector 41 is connected to the other end of the flexible hose 5.

[0048] In this embodiment, the water outlet device of the present invention further includes an installation assembly for fixing the device body 1 to the table surface. The installation assembly includes a pipe connector 9, a lock nut 10, a rubber gasket 91, and a washer 92. A base 8 is provided at the bottom of the vertical portion of the valve body 11. The base 8 is used to fix and support the control valve 2, and the base 8 is provided with internal threads. During installation, the pipe connector 9 is threadedly connected to the internal threads of the base 8, and the pipe connector 9 passes downward through the table surface, the rubber gasket 91, and the washer 92 before being threadedly tightened and fixed with the lock nut 10.

[0049] In a water outlet device of the present invention, when the solenoid valve 21 opens or closes instantaneously, the water pressure in the elastic hose 5 increases instantaneously. This instantaneous increase in water pressure successively expands the elastic hose 5 outwards at the three corners of the buffer section 51, forming protrusions 514, 515, and 516. The deformation of protrusion 514 at the first corner 511 is the largest, the deformation of protrusion 516 at the third corner 513 is the smallest, and the deformation of protrusion 515 at the second corner 512 is moderate. Figure 9 As shown. Therefore, the elastic hose 5 resists the instantaneous rise in water pressure through elastic deformation, which is equivalent to releasing and absorbing the impact force brought by the instantaneous pressure increase, thereby eliminating water noise, solving the problem of unstable water flow from large to small, ensuring that the water flow is constant, and solving the problem of short service life and leakage caused by water pressure impact on solenoid valve 21, aerator 42, etc., greatly improving the service life of the faucet.
