AI Technical Summary
Existing faucets make it difficult to visually determine the rotation status of the valve core, resulting in the valve core not being fully opened or closed, affecting the water flow control effect. This is especially true in environments with insufficient light or obstructed vision, where it is difficult to accurately determine the rotation position. Furthermore, long-term use can increase the difficulty of judgment due to valve core wear or scale accumulation.
A rotary positioning mechanism is designed, including a housing, a first valve core, a positioning ball, and an elastic component. The elastic component drives the positioning ball to move in the receiving hole, aligning it with the positioning groove to generate a collision sound, thereby achieving the positioning of the knob by rotation. The force is transmitted to the valve core through the screw-in connector to ensure accurate positioning.
It enables accurate positioning of the valve core rotation position in environments with insufficient light or obstructed vision, avoiding incomplete opening or closing of the valve core, improving water flow control accuracy, and reducing water waste.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom technology, and in particular to a rotary positioning mechanism and a faucet. Background Technology
[0002] A common problem in the design and application of existing faucets is that users find it difficult to visually determine the rotation status of the valve core and whether it has been fully rotated during operation. Traditional faucets typically rely on the user's feel and experience to estimate the rotation angle. This method is not only inaccurate but may also result in the valve core not being fully opened or closed, thus affecting water flow control and even wasting water. This is especially true in low-light or obstructed environments, where users find it even harder to accurately judge the faucet's rotation position. Furthermore, long-term use can lead to valve core wear or scale buildup, which can alter the rotation resistance and further complicate judgment. Therefore, we provide a rotary positioning mechanism and faucet to address these issues. Utility Model Content

[0031] like Figure 1— Figure 6 The example shown.
[0032] This application provides a rotary positioning mechanism, including a housing 100, a first valve core 200, a positioning ball 300, and an elastic component 400.
[0033] In some embodiments, the first valve core 200 is fixedly mounted on the housing 100, and a fixed wheel 210 is fixedly mounted on the outer end of the first valve core 200. The fixed wheel 210 has a receiving hole 211. A knob 220 is mounted on the drive shaft of the first valve core 200. A positioning groove 230 is provided on the end face of the knob 220 facing the first valve core 200. The positioning ball 300 is located in the receiving hole 211. The elastic component 400 is disposed in the receiving hole 211. The elastic component 400 drives the positioning ball 300 to be partially located outside the receiving hole 211.
[0034] See Figure 1 and Figure 2 As shown, both the positioning ball 300 and the elastic component 400 are located in the receiving hole 211. Under the elastic force of the elastic component 400, the positioning ball 300 is driven to move toward the knob 220. During the rotation of the knob 220, the positioning ball 300 can move due to the force it receives in the receiving hole 211. Therefore, when the positioning groove 230 touches the side wall of the positioning groove 230, the positioning ball 300 will move away from the knob 220 and move in the receiving hole 211 due to the force from the knob 220. After the positioning groove 230 rotates to the position of the positioning ball 300, the positioning ball 300 will partially protrude from the receiving hole 211 into the positioning groove 230 under the elastic force of the elastic component 400, thereby achieving positioning. When the positioning ball 300 partially enters the positioning groove 230, a collision will occur, which will produce a collision sound, thus confirming that the knob 220 has rotated to the predetermined position.
[0035] The fixed wheel 210 has a radially distributed fixed plate 212 inside, the receiving hole 211 axially penetrates the fixed plate 212, the positioning ball 300 is located inside the receiving hole 211, and the positioning ball 300 can move in the receiving hole 211 under force.
[0036] Please continue reading. Figure 2 As shown, in order to open the receiving hole 211 in the fixed wheel 210, a fixing plate 212 is provided in the radial direction inside the receiving hole 211. It can be understood that the fixing plate 212 is integrally formed with the fixed wheel 210, and the receiving hole 211 is opened through in the axial direction. It should be noted that the receiving hole 211 is not coaxial with the fixed wheel 210. That is to say, the receiving hole 211 is opened at the eccentric position of the fixing plate 212, so that it can correspond to the position of the positioning groove 230 on the knob 220.
[0037] The elastic component 400 includes a first elastic element 420 that blocks the port of the receiving hole 211 away from the knob 220. The first elastic element 420 is also provided in the receiving hole 211. The first elastic element 420 is located between the fixing stud 410 and the positioning ball 300. One end of the first elastic element 420 abuts against the positioning ball 300, and the end of the first elastic element 420 away from the positioning ball 300 abuts against the fixing stud 410.
[0038] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, in order to prevent the positioning ball 300 from dislodging in the receiving hole 211, a fixing stud 410 is installed in the opening of the receiving hole 211 away from the knob 220 for sealing and limiting. The size of the other opening of the receiving hole 211 is smaller than that of the positioning ball 300, and the first elastic member 420 is located between the fixing stud 410 and the positioning ball 300. Therefore, under the elastic force of the first elastic member 420, the positioning ball 300 partially protrudes out of the receiving hole 211.
[0039] In one embodiment, the first elastic element 420 may be a compression spring. It is understood that the first elastic element 420 may also be other elastic components, which are not limited here.
[0040] The knob 220 includes a driven housing 221 and a rotating block 222. The rotating block 222 is located on the end face of the driven housing 221 away from the first valve core 200. A connecting post 2211 is provided at the center of the driven housing 221. A connecting hole 223 is provided through the center of the driven housing 221 along the axis, and the connecting hole 223 extends to the outside of the rotating block 222.
[0041] A screw-on connector 224 is provided in the connection hole 223, and the screw-on connector 224 passes through the connection hole 223 to the first valve core 200 and is connected to the first valve core 200. The driven housing 221 is connected to the first valve core 200 through the screw-on connector 224.
[0042] Please continue reading. Figure 2 As shown, in order to transmit the turning force to the first valve core 200 via the knob 220, a connecting hole 223 is axially opened at the center position of the driven housing 221 and the rotating block 222, according to the attached diagram. Figure 2It can be seen that the connecting hole 223 passes through the connecting post 2211 and the rotating block 222 to achieve axial penetration. The connecting hole 223 is a stepped hole. The rotating connector 224 is placed in the connecting hole 223 and rotated until the rotating connector 224 is rotated into the first valve core 200. At this time, the stepped surface of the connecting hole 223 abuts against the stepped surface of the rotating connector 224 to achieve a limit, thereby realizing the transmission connection between the driven shell 221 and the shell 100. Furthermore, at this time, the rotating block 222 can be rotated to drive the driven shell 221 to rotate, thereby transmitting force to the shell 100 to achieve force transmission.
[0043] It is understandable that when the rotating block 222 drives the driven shell 221 to rotate and transmits force to the shell 100, the driven shell 221 will also drive the positioning groove 230 to rotate. When the positioning groove 230 and the positioning ball 300 are aligned, it indicates that the driven shell 221 and the rotating block 222 have rotated to the predetermined position and the screwing is completed.
[0044] A plug 225 is provided at the opening of the connection hole 223 away from the first valve core 200.
[0045] Please continue reading. Figure 2 As shown, in order to prevent foreign objects from entering the connection hole 223, a plug 225 is provided at the opening of the connection hole 223 away from the fixed wheel 210 to seal it and prevent foreign objects from entering the connection hole 223.
[0046] The diameter of the opening of the receiving hole 211 facing the knob 220 is L, and the diameter of the positioning ball 300 is D, satisfying that: D>L.
[0047] See Figure 5 As shown, in order to prevent the positioning ball 300 from detaching from the opening of the receiving hole 211 in the direction away from the fixing stud 410, the diameter of the positioning ball 300 needs to be larger than the diameter of the opening of the receiving hole 211 in the direction away from the fixing stud 410, so as to ensure that the positioning ball 300 can protrude partially without detaching from the receiving hole 211.
[0048] It should be noted that the opening of the receiving hole 211 facing away from the fixing stud 410 and the opening of the receiving hole 211 facing the knob 220 are the same opening. For details, please refer to [reference needed]. Figure 5 As shown.
[0049] The housing 100 is further equipped with a second valve core 500. A button seat 600 is provided at the end of the second valve core 500 away from the housing 100. A button body 800 is provided at the end of the button seat 600 away from the second valve core 500. A second elastic member 700 is provided between the button seat 600 and the button body 800.
[0050] Please see Figure 1 and Figure 6 As shown, pressing the button body 800 drives the second valve core 500 to dispense water. Pressing the button body 800 again stops the water dispensing from the second valve core 500. To ensure that the button body 800 returns to its initial position after each press and to prevent positional wobble during pressing, a button seat 600 is provided on the second valve core 500 to guide the button body 800. A second elastic element 700 is provided between the button body 800 and the button seat 600. The elastic force of the second elastic element 700 drives the button body 800 to rebound after each press, thus returning to its initial position and preventing jamming during pressing.
[0051] This application embodiment also provides a faucet, which includes the rotary positioning mechanism described above.
