A drinking water supply device configured to discharge water based on a pressure of water supplied from a water supply source is provided. The drinking water supply device may include at least one discharge flow path that allows water supplied from the water supply source to flow therein, a discharge valve provided in the at least one discharge flow path, at least one cock provided in an end of the at least one discharge valve, the discharge valve including a sensor that generates a discharge signal to open the at least one discharge valve, a lever coupled to the at least one cock and operated by pushing and pulling, and a controller that controls the at least one discharge valve and the sensor. The discharge signal may be generated in the sensor when a switch of the sensor is pressed by a predetermined region of the lever.

1. A drinking water supply device, comprising: at least one discharge flow path that allows water supplied from a water supply source to flow therein;a discharge valve provided in the at least one discharge flow path;at least one cock provided in an end of the at least one discharge flow path, the cock including a sensor that generates a discharge signal to open the at least one discharge valve;a lever coupled to the at least one cock and configured to be pushed or pulled; anda controller that controls the at least one discharge valve and the sensor,wherein the lever includes a manipulator manipulated by a user and a contact that selectively contacts with the sensor, the contact including a first contact configured to press a switch provided in the sensor when the manipulator is pushed and a second contact configured to press a switch provided in the sensor when the manipulator is pulled, andwherein the discharge signal is generated in the sensor when a switch of the sensor is pressed by a predetermined region of the lever. 2. The drinking water supply device of claim 1, wherein the switch of the sensor is pressed by the predetermined region of the lever when the lever is pushed or pulled. 3. The drinking water supply device of claim 1, wherein an end of the lever is configured to press the switch of the sensor when the lever is pushed or pulled at another longitudinal end thereof. 4. The drinking water supply device of claim 1, wherein the at least one cock includes a cock housing and a spring installing portion provided in the cock housing, a spring being provided between a side of the contact and the spring installing portion. 5. The drinking water supply device of claim 4, wherein the manipulator is provided in one end of the lever and the contact is provided in another end of the lever. 6. The drinking water supply device of claim 5, wherein a pair of supporting frames that extend from a width direction at an end of the manipulator are provided in the other end of the lever. 7. The drinking water supply device of claim 6, wherein the first contact extends backwards from a space formed between the pair of the supporting frames, and the second contact extends forwards from the space. 8. The drinking water supply device of claim 7, wherein a width of the first contact is smaller than a width of the space formed between the pair of the supporting frames, and a width of the second contact is larger than or equal to the width of the space formed between the pair of the supporting frames. 9. The drinking water supply device of claim 8, wherein the first contact and the second contact are inclined a preset angle with respect the manipulator, and the contact and the manipulator are integrally formed with each other. 10. The drinking water supply device of claim 7, wherein an upper surface of the second contact is planar and equal to an upper surface of the pair of supporting frames, and an upper surface of the first contact is inclined a preset angle with respect to the upper surface of the pair of supporting frames. 11. The drinking water supply device of claim 5, wherein the cock further includes a sensor installing portion in which the sensor is installed. 12. The drinking water supply device of claim 11, wherein the sensor installing portion and the first contact correspond to each other over the cock housing, and the sensor installing portion extends upwards at a preset angle from a top surface of the cock housing. 13. The drinking water supply device of claim 12, wherein the sensor is inclinedly installed in the sensor installing portion so that a front end of the sensor is higher than a rear end of the sensor. 14. The drinking water supply device of claim 13, wherein the sensor includes: a sensor housing;a switch projected from the sensor housing for signal input; anda leaf spring member provided to cover a free end of the switch, wherein, when the contact presses the leaf spring member, the switch is pressed by the leaf spring member. 15. The drinking water supply device of claim 14, wherein the switch is projected from a lower surface of the sensor housing, and the leaf spring member extends more forward than a front end of the sensor housing and extends a preset angle with respect to the lower surface of the sensor housing. 16. The drinking water supply device of claim 15, wherein the first contact is provided in a region overlapping the sensor along a longitudinal direction of the cock, and the second contact is provided in a region not overlapping the sensor along the longitudinal direction of the cock. 17. The drinking water supply device of claim 16, wherein the first contact or the second contact pushes the leaf spring member toward the switch for the leaf spring member to press the switch when the manipulator is pushed or pulled. 18. The drinking water supply device of claim 5, wherein when the manipulator is pulled to a preset angle or more from an initial location, a rear end of the second contact contacts with an upper surface of the cock housing and the manipulator then maintains a pulled state. 19. The drinking water supply device of claim 18, wherein when the manipulator is pulled to the preset angle or more from the initial location, a rear end of the second contact surface-contacts with an upper surface of the cock housing. 20. The drinking water supply device of claim 18, wherein when the manipulator maintains the pulled state, the second contact keeps pressing the switch of the sensor.
