New description: [New technical field] The present invention relates to a faucet, especially to a self-cleaning faucet. [Prior Art] Referring to Figure 1, the conventional faucet 丨 generally includes a body 丨丨The switch unit 12 is connected to the main body 11. The main body u includes a water outlet U1. The switch unit 12 is located above the water outlet U1. The switch unit 12 can be operated to control whether the water outlet is out of water. When the hand washing operation is performed, the switch unit 12 is first turned on to discharge the water outlet, and the switch unit 12 is turned off after the hand is washed. However, when the switch unit 12 is turned on, the hand that has not been cleaned may contaminate the switch single 12, so in order to avoid cross-infection, the water tap is first washed with water after washing the hand. The switch unit 12 prevents the cleaned hand from coming into contact with the sweat-dyed switch unit 12 and is again contaminated. However, there are the following shortcomings: —: Hand holding the water to clean the switch unit 12 This action must first take the hand _ Quantitative water and then hold the water to the top of the unit 12 and pour it down to clean, if necessary, a lot of water Flushing also needs to repeat the trouble of using the water several times, & s + + & + 贞 and in this private faucet i still continue to effluent, resulting in a lot of waste of water source, the water source is increasingly dry Today, the waste of water sources is quite serious and must be improved immediately. '[New content] Therefore, the purpose of the present invention is to provide a self-cleaning faucet that can conveniently and economically save the switch of the 3 M412288 cleaning faucet. Thus, the present self-clearing water shovel - a flying faucet pack 3 - a body, a switch unit ' and a catheter single it. The body is hollow and has a first open end, a second open end, and a third open end, connected to the water source. The switch is pre-set at the second open end for the user to determine whether the first open end and the third open end are connected or not. The conduit unit is disposed at the third open end and has a water outlet. When the first open end and the third open end are in communication, the water source flows out through the water outlet to generate a water outlet located above the switch unit. The water outlet is provided for the user to guide by hand to flow through the switch unit. The effect of the novel is that the user can guide the flow of water through the switch unit, thereby easily washing the switch unit, thereby preventing the father from being infected more easily, and saving water during the washing process. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 2 and 3, a preferred embodiment of the self-cleaning faucet comprises a body 2, a switch unit 3, and a duct unit 4. The body 2 is hollow and has a first open end 21, a second open end 22, and a third open end 23 connected to a water source (not shown). The switch unit 3 is disposed at the second open end 22' for the user to determine whether the first open end 21 and the third open end 23 are connected. The duct unit 4 is disposed at the third open end 23' and includes a universal joint 4, a water outlet head 42, a water outlet 43, and a gauze 44. One end of the guide is disposed at the third open of the body 2. The other end of the guide S 41 is connected to the water outlet head 42. The water outlet 43 of the duct unit 4 is formed on the water outlet head 42 and located above the switch unit 3. The gauze 44 is disposed at The water outlet 43. When the first open end 21 is in communication with the third open end 23, the water source flows out from the water outlet 43 through the gauze 44, and the water flow is multi-channel by the gauze 44, and the water flow is increased. The area is used to improve the washing effect and achieve water saving purposes. More importantly, 'Refer to Figure 4' when the hand washing action is completed, ready to close, switch unit 3 'because the water flow generated by the water outlet 43 is flowing out from the switch 7G 3 early', the person only needs to guide with the hand to Flowing through the switch unit 3', the switch unit 3 can be cleaned by a clean money line, and the switch unit 3 contaminated by the hand before washing is washed, and the switch unit 3 can be turned off without being contaminated after washing. Since the switch unit 3 is directly guided by the water flow during the cleaning process, water waste caused by washing the conventional faucet with the hand holding water does not occur, and in addition, it is not necessary to repeat the water washing after repeated washing with a large amount of water. The action of the present invention is quite convenient when cleaning the switch unit 3. It is worth mentioning that since the water outlet head 42 is attached to one end of the universal duct 41, the position of the water outlet 43 can be adjusted by adjusting the universal duct 41. The user can thereby adjust the water outlet 43. The position is more convenient for use in accordance with the user's body shape or usage habits. M412288 In summary, the position of the water outlet 43 is located above the switch unit 3, and the user can guide the water flow through the switch single A 3 to clean the water by hand, which is convenient and saves water resources. The shirt can achieve the purpose of this new type. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the novel patent application scope and the new description content are all It is still within the scope of this new patent.
