Title: Double-waterway faucet structure

Description:
RELATED APPLICATIONS 
     This application claims priority to Chinese patent application number 202122635780.5, filed on Oct. 29, 2021. Chinese patent application number 202122635780.5 is incorporated herein by reference. 
     FIELD OF THE DISCLOSURE 
     The present disclosure relates to a double-waterway faucet structure. 
     BACKGROUND OF THE DISCLOSURE 
     The traditional faucet only has a single water path structure, and the single water path structure is controlled by a single valve to achieve switching, which has a relatively simple water outlet function. 
     For example, Chinese patent application number 201921346078.3 discloses a dual-purpose faucet for kitchen and water purification, comprising a faucet body, a water purifier, a touch screen assembly, a handle, and a control valve. The faucet body comprises a tap water path and a purified water path. The control valve is installed on the faucet body and can control a turning ON and OFF of the tap water path and a flow rate of water that is flowing in the tap water path. The handle can move relative to the faucet body and is operatively coupled to the control valve. The touch screen assembly comprises a touch screen, a control circuit for the touch screen, and a solenoid valve. The purified water path passes through the water purifier and the solenoid valve. The touch screen is fixed on the faucet body, is located outside the control valve, and is arranged coaxially with the control valve. The control circuit is installed on the faucet body and is electrically connected to each of the touch screen and the solenoid valve. The solenoid valve is electrically connected with the water purifier. Although the dual-purpose faucet has two independent water passages, the faucet body is fixed, the two water passages cannot be rotated according to the required positions, and the two water passages cannot be pulled out for changing a water outlet direction of the two independent water passages, which is inconvenient for a user. 
     BRIEF SUMMARY OF THE DISCLOSURE 
     The present disclosure provides a double-waterway faucet structure to solve the deficiencies in the background. 
     In order to solve the technical problem, a technical solution of the present disclosure is as follows. 
     A double-waterway faucet structure comprises a faucet body, a rotating bracket, a pull-out head, a solenoid valve, and a control valve. The faucet body comprises a first water inlet passage, a second water inlet passage, and a first water outlet passage configured to be in communication with the first water inlet passage. The first water outlet passage is connected to the pull-out head. The control valve is disposed on the faucet body and is configured to control a turning ON and OFF between the first water inlet passage and the first water outlet passage. The rotating bracket is rotatably disposed on the faucet body and comprises a second water outlet passage configured to be in communication with the second water inlet passage, and the solenoid valve is disposed on the second water inlet passage to control a turning ON and OFF of the second water outlet passage. 
     In a preferred embodiment, the faucet body comprises a housing body, a valve body, and a fixed sleeve. The valve body is fixedly connected in the housing body. The control valve is disposed in the housing body and matched with the valve body. The fixed sleeve is fixedly connected to the housing body. The rotating bracket comprises a rotating sleeve extending along a vertical direction and a supporting rod fixedly connected to the rotating sleeve and extending along a lateral direction, and the rotating sleeve is rotatably sleeved on an outer periphery of the fixed sleeve. A water-passing passage is defined between the rotating sleeve and the fixed sleeve, the supporting rod comprises the second water outlet passage, and the water-passing passage is in communication with each of the second water inlet passage and the second water outlet passage. 
     In a preferred embodiment, the double-waterway faucet structure comprises a supporting spring. The supporting spring is fixedly connected to a top end of the rotating sleeve and is configured to rotate with rotation of the rotating sleeve, and the first water outlet passage passes through the housing body, the fixed sleeve, and the supporting spring to extend out of the supporting spring to be connected to the pull-out head. 
     In a preferred embodiment, the double-waterway faucet structure comprises a first bushing. A top end of the housing body comprises a fixed protrusion extending upward, and a bottom end of the fixed sleeve is disposed in the fixed protrusion. The first bushing is sleeved on an outer periphery of the fixed protrusion, and a bottom end of the rotating sleeve is sleeved on an outer periphery of the first bushing. 
     In a preferred embodiment, the double-waterway faucet structure comprises a second bushing. The outer periphery of the fixed sleeve comprises a position-limiting protrusion. The second bushing is sleeved on the outer periphery of the fixed sleeve, and a bottom end of the second bushing abuts the position-limiting protrusion. The top end of the rotating sleeve is sleeved on an outer periphery of the second bushing. 
     In a preferred embodiment, the double-waterway faucet structure comprises a connecting sleeve. An inner wall of the top end of the rotating sleeve comprises a stepped surface, and the connecting sleeve is fixedly connected to the inner wall of the top end of the rotating sleeve. A bottom end of the connecting sleeve abuts the stepped surface, and a bottom end of the supporting spring is sleeved outside the connecting sleeve. 
     In a preferred embodiment, a distal end of the supporting rod comprises a snapping ring having an opening, and the pull-out head is configured to be detachably snapped to the snapping ring. 
     In a preferred embodiment, a water purification filter is disposed on the second water inlet passage. 
     In a preferred embodiment, the first water inlet passage comprises a cold water inlet passage and a hot water inlet passage, and the control valve is configured to control a temperature of water flowing in the first water outlet passage. 
     Compared with the existing techniques, the technical solution has the following advantages. 
     1. The double-waterway faucet structure not only has two independently controlled water outlet passages, but also the first water outlet passage is connected to the pull-out head. That is, the double-waterway faucet structure also has a pull-out function, which is more convenient for users to use. At the same time, the second water outlet passage can rotate with rotation of the rotating bracket, and a water outlet direction of the second water outlet passage can be changed according to a position of a water sink, which is more convenient to use. 
     2. The bottom end of the rotating sleeve is sleeved on the outer periphery of the first bushing, and the top end of the rotating sleeve is sleeved on the outer periphery of the second bushing, which can prevent the rotating sleeve from shaking. 
     3. The pull-out head can be detachably snapped to the snapping ring, which makes it more convenient to use the pull-out head. When a user has finished using the pull-out head, the pull-out head can be snapped to the snapping ring for positioning. 
     4. The water purification filter is disposed on the second water inlet passage, so that the second water outlet passage can output purified water.
