Description

Technical Field

[0001] The invention relates to a multifunctional switching water channel. Background Art

[0002] The nozzles of the existing extractable kitchen faucets are often equipped with more than two functional water splashes to meet the needs of use in different occasions. The two-function nozzles are generally configured as bubble water and shower water, and bubble water is the commonly used default water. The three-function nozzles are generally configured as bubble water, shower water + a special function water splash, and bubble water is the commonly used default water. As the functional water splash increases, more buttons must be designed on the nozzle for switching the water splashes. Analyzing from the existing products, the two-function extractable nozzles generally use two buttons or a seesaw-type independent button to achieve switching between water splashes. Generally, the two water splashes can be switched freely, and both can maintain the water discharge state. After the water is cut off, the bubble water function is reset to the bubble water function. The next time the water is turned on, the bubble water can be defaulted. The three-function extractable nozzles generally use a seesaw-type independent button + an ordinary long-press button. Generally, each water splash can be switched freely. The bubble water and shower water can maintain the water discharge state. The functional water splash needs to be long pressed to maintain the water discharge state. After the water is cut off, it has the function of resetting to the bubble water.

[0003] In view of the above analysis, the 3-function shower head can bring more choices and experiences to users, and the user scalability will be relatively strong, which is a more valuable product. However, the button usage logic of the above 3-function shower head is not the optimal solution. The seesaw-type button makes the water splash selection unclear during use, and the human-computer experience is not good. The functional water splash needs to be pressed for a long time instead of pressed once to maintain the water state, and the experience is not good. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Reference Manual Attached Figure 1-2 A multifunctional switching waterway comprises a waterway component, a control valve component, a switching valve component and a linkage, wherein two ends of the waterway component are respectively arranged as an inlet end and an outlet end.

[0031] Reference Manual Attached Figure 3-5A main channel is arranged in the water channel assembly, a first valve hole is arranged between the main channel and the inlet end, the control valve assembly is installed in the first valve hole, a second valve hole and a third valve hole are also arranged between the first valve hole and the outlet end of the main channel, a second channel and a third channel are arranged in the second valve hole and the third valve hole respectively, and the switching valve assembly is installed in the second valve hole and the third valve hole respectively; the control valve assembly is used to control the pressure of the second channel and the third channel, the switching valve assembly is used to switch the connection between the main channel and the second channel or the third channel, and the switching valve assembly can realize the function of mutual driving and switching through a linkage.

[0032] Reference Manual Attached Figure 6-7 The switching valve assembly includes a first elastic member and a first center bolt assembly. The first center bolt assembly includes a first outer ring and a first center bolt located in the first outer ring. The first outer ring is relatively fixed to the waterway assembly. The center of the first center bolt can move up and down along the axis under the interaction of the external force and the first elastic member. The switching valve assembly includes a first pressure-bearing surface and a second pressure-bearing surface. The area of ​​the first pressure-bearing surface is larger than the second pressure-bearing surface. Since the first pressure-bearing area is larger than the second pressure-bearing area, when there is liquid flowing in the waterway, after the external force is removed, the first center bolt maintains a downward position along the axis under the action of hydraulic pressure, so that the corresponding flow channel remains connected with the main flow channel; when the liquid is disconnected and the hydraulic pressure disappears, the first center bolt maintains an upward position along the axis under the action of the first elastic member, so that the main flow channel is restored to be connected with the corresponding outlet end.

[0033] Reference Manual Attached Figure 8-9 , the control valve assembly controls the pressure of the second and third flow channels by controlling the size of the liquid passage of the main flow channel; the control valve assembly includes a second elastic member and a second center plug assembly, the second center plug assembly includes a second outer ring and a second center plug located in the second outer ring, the second outer ring is relatively fixed to the water channel assembly, and the second center plug can move up and down along the axis in the second outer ring under the interaction of external force and the second elastic member, and the second center plug assembly includes a third pressure-bearing surface and a fourth pressure-bearing surface, and the axial projection areas of the third and fourth pressure-bearing surfaces are equal. Since the areas of the third and fourth pressure-bearing surfaces are equal, even when there is liquid flowing in the flow channel, after the external force is removed, under the action of the second elastic member, the second center plug will always maintain an upward posture along the axis, so that the inlet end and the main flow channel are always connected.

[0034] Reference Manual Attached Figure 10-11 , a first key cap is disposed above the control valve assembly, and a second key cap and a third key cap are disposed above the switching valve assembly. Figure 4 and 11The outlet end further comprises a main outlet end located at the center of the outlet end, second outlet ends located at both sides of the main outlet end, and a third outlet end arranged around the main outlet end. The main outlet end corresponds to the outlet of the main flow channel, the second outlet end corresponds to the outlet of the second flow channel, and the third outlet end corresponds to the outlet of the third flow channel.

[0035] When the key cap 603 corresponding to the switching valve near the outlet is pressed, refer to the attached manual. Fig.12 At this time, water flows out of the third outlet, and the water is cut off from the main outlet. Release the key cap corresponding to the switching valve closest to the outlet, and the third outlet keeps flowing out water.

[0036] When the key cap 602 corresponding to the switching valve near the inlet end is pressed, refer to the attached manual. Fig.13 , water flows out of the second outlet, release your hand, the second outlet continues to flow water, and at the same time, the water to the switching valve assembly installed in the third valve hole is disconnected, and the center bolt of the switching valve assembly in the third valve hole rebounds to the initial position.

[0037] When the key cap 601 corresponding to the control valve is pressed, refer to the attached manual. Fig.14 , the water flowing to the switching valve assembly is completely reduced or cut off, and the center plugs corresponding to the switching valve assembly all rebound to the initial position. Release your hand, and the control valve assembly returns to the initial position under the action of the second elastic member. At this moment, the water outflow state of the main outlet is still maintained.

[0038] The switching valve assembly where the third keycap and the second keycap are located can switch with each other during water use because of the existence of a linkage part, thereby realizing the switching between the third outlet port and the second outlet port, and once the water is cut off, the water path defaults to: from the main channel to the main outlet port, thereby realizing the default water function. The above scheme not only realizes the default water outlet mode of the pull-out sprinkler, but also realizes independent control and switching between different outlet ports, and can ensure that each outlet port can maintain a continuous water outlet state.

[0039] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
