The branch section 164 is bent again in a direction away from the straight portion to form a first pin hole 164H1 at a portion adjacent to the point where the bending extension starts, and a second pin hole 164H2 at the distal end. .

The straight portion 162 of the first force shifting member 160 is inserted between the protrusions 154 of the lever fixing member 150, and the pin holes 156 of the protrusions 154 and the slits of the straight portion 162 ( The pin 132B passing through 162S and the nut 132N coupled to the pin 132B are displaceably coupled between the protrusion 154 of the lever fixing member 150. Accordingly, the lever fixing member 150 and the first force shifting member 160 are slidably rotatably coupled to each other. That is, the pin 132B may slide in the slit 162S of the straight section 162 in a state of being fixed to the lever fixing member 150, whereby the first force shifting member 160 will be described later. It can rotate around the pin (not shown) inserted in the 1st pin hole 164H1.

The side section 124 of the mounting frame 120 is formed with a second pin hole 124H2 corresponding to the first pin hole 164H1 of the first force switching member 160, and these pin holes 164H1 and 124H2. ) Are coupled to each other by pins and nuts (not shown) having substantially the same configuration as the aforementioned pins 132B and nuts 132N.

Thus, the first force diverting member 160 is coupled to the side section 124 of the mounting frame 120 so as to be able to hinge about the first pin hole 164H1.

As specifically shown in FIGS. 8 and 9, the second force diverting member 170 is entirely stepped and consists of a first section 172, a connecting section 174 and a second section 176. The first section 172 includes a slit 172S, an elastic piece 178 therein, and a locking protrusion 180 protruding into the slit 172S at an end of the elastic piece 178 therein. The elastic piece 178 is formed by removing a portion of the first section 172 on one side of the slit 172S, and the locking protrusion 180 is positioned near the middle in the longitudinal direction of the slit 172S. In addition, the first section 172 further includes a pin hole 172H formed adjacent to the connecting section 174. The slit 176S is formed in the second section 176.

The pin 134B is formed in the second pin hole 164H2 of the slit 174S of the second section 176 of the second force switching member 170 and the branching section 164 of the first force switching member 160 corresponding thereto. ) Is inserted and the nut 134N is coupled to the pin 134B. Accordingly, the pin 134B may slide along the slit 174S of the second force switching member 170 while rotating in the second pin hole 164H2 of the first force switching member 160.

A pin 136B is inserted into the slit 172S of the first section 172 of the second force converting member 170 and the slit 112 of the cap 110 corresponding thereto, and the nut 136N is inserted into the pin 136B. Combined with Accordingly, the second force diverting member 170 is slidably rotatable with the cap 110. That is, the pin 136B can slide along the slit 172S of the first section 172 of the second force switching member 170 and the slit 112 of the cap 110 and the second force switching member 170. The cap 110 can rotate relative to each other.

The first and second force conversion members 160 and 170 as described above do not convert the force itself into other forms, but convert the linear motion into the curved motion while simultaneously converting the direction of the force. Accordingly, the first and second force shifting members 160 and 170 may be collectively referred to as “curve force shifting units” different from the push lever 140 and the lever fixing member 150 collectively referred to as linear force transmission units.

Hereinafter, the operation of the cock contamination prevention apparatus 100 of the present invention will be described with reference to FIGS. 11 to 14.

At this time, the first force switching member 160 rotates in the clockwise direction, the second force switching member 170 rotates in the counterclockwise direction to move to the position shown in FIG.

In this state, the user receives the purified water from the cocks 10 and 12 using the cup. The cap 110 then returns to the position of FIG. 10 when the user releases the cup completely from the push lever 140.

In this way, the caps 110 and 12 may be covered and protected by the cap 110, and the cap 110 may be conveniently opened when receiving the purified water, and the caps 110 and 12 may be covered after use. ) Can be moved back to the standby position.

On the other hand, when the cap 110 is in the position of FIG. 11, when the user pushes the cap 110 back by hand, the cap 110 rotates to the position of FIG. 12. When the pushing force is released, the cap 110 attempts to return to the position of FIG. 10 by its own weight, but as shown in FIG. 14, the locking protrusion 180 of the elastic piece 178 contacts the pin 136B. By preventing the pin 136B from moving anymore, the entire cock contamination prevention device 100 stays in the position of FIG. 13.

In this way, the user can conveniently receive the integer without having to press the push button (140 of FIG. 10). This is particularly convenient when receiving large quantities of integers.

After receiving the purified water, the cap 110 is returned to the position of FIG.

In FIG. 12, reference numeral P denotes a completion position. When the connection point (see pin 136B of FIG. 6) between the cap 110 and the second force switching member 170 reaches the completion position P, the cap ( 110 is fully open and the user can receive an integer.

At this time, it has a relationship of B> A. That is, the position of the hinge center (the central axis of the hinge pin 116B) of the second force conversion member 170 and the elastic piece 178 of the first section 172 should be set such that the above relationship holds.

FIG. 15 is a cross-sectional view of the cock contamination preventing apparatus 100-1 according to the second embodiment of the present invention.

This makes the return of the cap 110 elastic and can quickly cover and protect the cock. In addition, the operation of returning from the fixed position of FIG. 13 can be performed more easily.

As such a spring 170, a coil spring is preferable. In addition, other suitable elastic bodies may be used instead of the springs.

FIG. 16 is a cross-sectional view of the cock contamination prevention apparatus 100-2 according to the third embodiment of the present invention. The cock contamination prevention apparatus 100-2 shown in FIG. 16 installs the push button 140a and the actuator 190 instead of the push lever 140 of the first embodiment, and replaces the lever fixing member 150 with a power transmission member ( 150a) is different. That is, when the user presses the push button 140a instead of operating the cap driving mechanism 130 by the force of pushing the push lever 140, the actuator 190 pushes the power transmission member 150a to the left of FIG. 16. Accordingly, the cap 110 is rotated through the first and second force conversion members 160 and 170. In addition, after use, the actuator 190 is driven in the reverse direction to return the cap 110 to its original position. Of course, it can also be configured to recover by the weight of the cap 110 itself.

As the actuator 190 usable, various known ones are possible, and an actuator using electromagnetic force will be preferable.

Thus, using the actuator 190, the cap 110 can be more conveniently rotated between the standby position and the open position.

Although the above has been described with reference to the preferred embodiments of the present invention, those skilled in the art may vary the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It will be understood that modifications and variations can be made.

As described above, according to the present invention, the cock can be easily covered and protected by a cap. In addition, since the drive mechanism is attached, the cap can be conveniently opened when receiving purified water, and the cap can be moved back to the standby position so as to cover the cock after use. In addition, mounting the actuator to the drive mechanism allows for a more convenient rotation of the cap between the standby and open positions.
