Detailed Embodiments

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to the attached drawings of the specification, a switching structure includes a body (10). A water distribution part (20) is provided on the body (10). One end of the water distribution part (20) is connected to a first water passage (30), and the other end of the water distribution part (20) is connected to a second water passage (40). The first water passage (30) is connected to a first water outlet (51), and the second water passage (40) is connected to a second water outlet (52). It is characterized in that: a plug switch (60) is provided in the first water passage (30), a cavity (70) is provided between the first water passage (30) and the second water passage (40), and a movable control member (80) is provided in the cavity (70). The control member (80) realizes switching control of the water outlet of the first water outlet (51) or the second water outlet (52) by moving in the cavity (70). With the above structure, the present invention realizes the switching of two waterways by one control member (80).

[0023] Furthermore, a first water inlet (91) is provided between the plug switch (60) and the control member (80), and a second water inlet (92) is provided between the other end of the water distribution part (20) and the control member (80). The user controls the plug switch (60) to close or open the first water inlet (91). When the plug switch (60) closes the first water inlet (91), the water source cannot enter the first water passage (30), so that the control member (80) cannot be impacted, and thus the rightward movement of the control member (80) cannot be realized, and the opening of the first water outlet (51) cannot be realized. At this time, the first water outlet (51) does not discharge water. When the plug switch (60) is not in contact with the first water inlet (91), that is, the first water inlet (91) is opened, at this time, the water source can enter the first water passage (30), so as to impact the control member (80), causing the control member (80) to move to the right, thereby realizing the opening of the first water outlet (51). At this time, the first water outlet (51) discharges water.

[0024] Furthermore, the control member (80) includes a pressing shaft (81) and a switching bolt (82). A spring (85) is provided between the pressing shaft (81) and the switching bolt (82), and a sealing ring (83) is provided on the switching bolt (82).

[0025] Furthermore, a limiting surface (811) is provided at one end of the pressing shaft (81), a first convex column (812) is provided at the other end of the pressing shaft (81), a sunk groove (821) is provided at one end of the switching bolt (82), and a second convex column (822) is provided at the other end of the switching bolt (82). One end of the spring (85) is sleeved on the first convex column (812), and the other end of the spring (85) is nested in the sunk groove (821).

[0026] Further, a mating surface (10a) that mates with the limiting surface (811) is provided inside the body (10), and a groove (10b) that mates with the second convex post (822) is provided inside the body (10). When the limiting surface (811) contacts the mating surface (10a), a limit value of the movement of the control member (80) within the cavity (70) is reached; when the second convex post (822) contacts the bottom of the groove (10b), another limit value of the movement of the control member (80) within the cavity (70) is reached.

[0027] Further, the sealing ring (83) includes a first sealing ring (831) and a second sealing ring (832). The first sealing ring (831) ensures the sealing performance of the second water inlet (92), and the second sealing ring (832) ensures the sealing performance between the first water passage (30) and the second water passage (40). When the plug switch (60) is opened, water from the water source enters the first water passage (30), and the water source impacts the control member (80), causing the control member (80) to move rightward within the cavity (70). The first sealing ring (831) seals the second water inlet (92), thereby achieving no water flow from the second water outlet (52); the provision of the second sealing ring (832) prevents water leakage between the first water passage (60) and the second water passage (70) after the water source enters the cavity (70), ensuring that the first water outlet (51) and the second water outlet (52) do not discharge water simultaneously.

[0028] During use, when there is no water inlet in the main body (10), under the action of the spring (85), the limiting surface (811) contacts the mating surface (10a), the second convex post (822) contacts the bottom of the groove (10b), and the compressed length of the spring (85) is H1. At this time, the elastic force provided by the spring (85) is F = K*(H - H1), where K is the elastic coefficient of the spring (85) and H is the free length of the spring (85); when the plug switch (60) is opened, that is, the plug switch (60) does not contact the first water inlet (91), the first water passage (30) is opened. After the water source enters the main body (10), it flows into the first water passage (30) through the first water inlet (91), and then the water source impacts the pressure shaft (81) of the control member (80), causing the control member (80) to move to the right in the cavity (70). The first sealing ring (831) completely blocks the second water inlet (92), and the water source flows out from the first water outlet (51), forming the first water outlet state. At this time, the compressed length of the spring (85) is H2, so the elastic force provided by the spring (85) at this time is F1 = K*(H - H2); when the plug switch (60) is closed, that is, the plug switch (60) contacts the first water inlet (91), the first water passage (30) is closed, and the water source cannot enter the first water passage (30) to impact the pressure shaft (81). Therefore, the water source flows in the direction of the second water passage (40), impacts the switching bolt (82) on the control member (80), and under the impact of the water source, the control member (80) moves to the left in the cavity (70) until the limiting surface (811) contacts the mating surface (10a). At this time, the compressed length of the spring (85) is H3, and the elastic force provided by the spring (85) at this time is F2 = K*(H - H3). When the plug switch (60) is opened, the water pressure impacting the pressure shaft (81) is greater than the water pressure impacting the switching bolt (82). Therefore, when the plug switch (60) is opened, the control member (80) is still located at the rightmost end of the cavity (70), and the second water outlet (52) does not discharge water.

[0029] As shown in the attached Figure 2-4 specification, the compressed length of the spring (85) is H > H1 > H3 > H2. Therefore, the elastic force provided by the compressed spring (85) is F < F2 < F1. Therefore, in the second water outlet state, only a little bit of the elastic force of the spring (85) needs to be overcome to make the first sealing ring (831) not block the second water inlet (92), so as to realize the water discharge of the second water outlet (52); while in the first water outlet state, the spring (85) provides a greater elastic force. Therefore, the first sealing ring (831) can tightly block the second water inlet (92). Even if the switching bolt (82) is impacted by high pressure, the failure of the water passing state will not occur, thus ensuring the reliability of high-pressure water and low-pressure water.
