Technical Field

[0001] The utility model relates to the field of valves, in particular to a double-water-outlet switching valve body structure. Background Art

[0002] The existing single-inlet and single-outlet faucets have a fixed water outlet effect due to the single water channel inside, and cannot meet the user's demand for multiple water outlet effects (i.e., the effect of conventional water outlet and the effect of water outlet foaming). Therefore, due to the above-mentioned usage requirements, single-inlet and double-outlet faucets have also appeared on the market, but such faucets are mostly integrated structures, which not only increases the difficulty of manufacturing parts and components, but also increases the difficulty of assembly. At the same time, it is not easy to repair in subsequent use, and there is a situation where the overall replacement and repair increase the cost of use. Utility Model Content

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0030] See also Figure 1-Figure 8The present embodiment provides a dual-outlet switching valve body structure, including a valve body 1 and a switching member 2. The valve body 1 is provided with a first water outlet chamber 11 and a second water outlet chamber 12. The first water outlet chamber 11 and the second water outlet chamber 12 are both provided with a water inlet 13 and a water outlet 14. The water inlet 13 of the first water outlet chamber 11 is provided with a mounting member 3. The mounting member 3 is a structure with openings at both ends. The mounting member 3 is detachably connected to the valve body 1 and a water inlet joint 51 is detachably mounted thereon via a buckle assembly 4. A connecting port 15 is provided on a water outlet chamber 11, and the second water outlet chamber 12 can be connected to the connecting port 15 through the water inlet 13 thereon to achieve communication with the first water outlet chamber 11. The switching member 2 is rotatably connected to the valve body 1 and is driven by an external force to rotate relative to the valve body 1. A three-way channel 21 is provided on the switching member 2, and the three-way channel 21 is located in the first water outlet chamber 11. The water inlet 13 of the first water outlet chamber 11 is connected to the water outlet 14 or the connecting port 15 thereon through the three-way channel 21.

[0031] In this embodiment, the mounting member 3 and the valve body 1 are connected by threaded fitting, and the three-way channel 21 is in a T-shaped structure, which reduces the difficulty of opening the three-way channel 21 on the switching member 2, reduces manufacturing losses, and ensures manufacturing efficiency.

[0032] See also Figure 1 The water inlet 13 and the connecting port 15 of the second water outlet chamber 12 are on the same horizontal plane and are located on the same side of the valve body 1, thereby improving the convenience of connection between the water inlet 13 and the connecting port 15 of the second water outlet chamber 12.

[0033] In this embodiment, the water inlet 13 of the second water outlet chamber 12 and the connecting port 15 can be directly connected by a water pipe, so as to realize the communication between the first water outlet chamber 11 and the second water outlet chamber 12, or the connection can be realized through a filter (that is, the water inlet of the filter is connected to the connecting port 15, and the water outlet of the filter is connected to the water inlet 13 of the second water outlet chamber 12), so as to improve the quality of the water output.

[0034] See also Figure 1 , Figure 2 The water inlet 13 and the connecting port 15 of the second water outlet chamber 12 are both provided with a connector 52, and the water outlet 14 of the second water outlet chamber 12 is provided with a rotating joint 53, which improves the connection convenience and also enables the water outlet faucet connected to the second water outlet chamber 12 to rotate relative to the valve body 1, so as to adjust the water outlet position. Figure 8 as shown in .

[0035] See also Figure 2-Figure 5The buckle assembly 4 includes a limit sleeve 41 and a plurality of steel balls 42. The limit sleeve 41 is sleeved on the mounting. A spring 43 is provided between the limit sleeve 41 and the valve body 1. The two ends of the spring 43 respectively abut against the limit sleeve 41 and the valve body 1. A limit portion 44 is provided on the water inlet joint 51 for preventing the limit sleeve 41 from being separated from the mounting member 3. A plurality of through holes 45 are provided on the mounting member 3 along the axis thereof at equal angles. The through holes 45 correspond to the steel balls 42 one by one. The depth of the through holes 45 is less than the diameter of the steel balls 42. A groove 46 for accommodating the inner end of the steel ball 42 is provided on the outer surface of the water inlet joint 51. When the water inlet joint 51 is inserted and installed on the mounting member 3, the inner end of the steel ball 42 is located in the groove 46 and its two ends abut against the limit sleeve 41 and the water inlet joint 51 respectively.

[0036] The limiting sleeve 41 limits the movable space of the steel ball 42 under the action of the spring 43, thereby ensuring the stability of the connection between the water inlet joint 51 and the mounting member 3, and also facilitating the disassembly and replacement of the water inlet joint 51 (i.e., the limiting sleeve 41 is pushed, the spring 43 is compressed, so that the limiting sleeve 41 is shifted to release the restriction on the movement of the steel ball 42, so that when the water inlet joint 51 is pulled out from the mounting member 3, the steel ball 42 can move outward through the through hole 45, the inner end of the steel ball 42 is disengaged from the groove 46, and the connection between the water inlet joint 51 and the mounting member 3 is released), thereby improving the flexibility and scope of application of the device.

[0037] See also Figure 3 , Figure 4 A water outlet head 6 is detachably mounted on the water outlet 14 of the first water outlet chamber 11, and a plurality of separation rings 61 are sandwiched between the water outlet head 6 and the valve body 1. A plurality of stacked metal meshes 62 are sandwiched between the water outlet head 6 and the separation rings 61 and between adjacent separation rings 61, which can filter the output water flow while slowing down the output water flow, reduce the impact force, and improve the effect of water outlet use.

[0038] In this embodiment, the water outlet head 6 and the valve body 1 are connected by threaded fitting.

[0039] See also Figure 4 , Figure 5 An annular groove 31 for accommodating the outer end of the steel ball 42 is provided on the inner side surface of the top of the limiting sleeve 41. When the limiting sleeve 41 is pushed to release the restriction on the movement of the steel ball 42, the outer end of the steel ball 42 can enter the annular groove 31 from the through hole 45, so that the steel ball 42 is located between the limiting sleeve 41 and the mounting member 3, reducing the risk of the steel ball 42 falling off and missing, and ensuring the integrity of the device.

[0040] See also Figure 5 , Figure 6The valve body 1 is provided with a slider 7, which is located between the mounting member 3 and the switching member 2. A slide groove 71 for the slider 7 to slide is provided on the outer surface of the switching member 2 along its circumferential direction. The slider 7 and the slide groove 71 are used in conjunction with each other to improve the control of the rotation of the switching member 2, thereby ensuring the smoothness and effectiveness of the switching operation.

[0041] See also Figure 6 , Figure 7 A damping block 22 is embedded in the switching member 2 and sandwiched between the switching member 2 and the valve body 1, so that the damping block 22 can limit the rotation of the switching member 2 relative to the valve body 1 when no external force is applied, thereby ensuring the stability of the switching member 2 and the valve body 1 in a relatively static state.

[0042] In this embodiment, in order to ensure the sealing effect of the valve body structure, sealing rings 8 are provided between the water inlet joint 51 and the mounting member 3, between the mounting member 3 and the valve body 1, between the switching member 2 and the valve body 1, between the water outlet head 6 and the valve body 1, and between the rotating joint 53 and the valve body 1.
