As shown in fig. 18 to 21, the present invention further provides a second embodiment of a bowl tap 1, the bowl tap 1 being substantially the same as the bowl tap 1 of the first embodiment, with the only difference:

the inner outlet pipe 60a in this embodiment is formed by inserting a hose 65 between the water inlet joint 63a and the water outlet head 64 a.

The inner body 30a of this embodiment is not designed with the adapter 314 of the first embodiment, so that a portion of the water inlet 63a of this embodiment is directly inserted into the mixed water outlet 313.

In addition, since the hose 65 has no rigid characteristics of rigid material, even if the outlet head 64a can be inserted and fixed in the outer body 10 as in the first embodiment, the water inlet joint 63a inserted into the mixed water outlet 313 cannot be released. Therefore, the inner body 30a of the embodiment is provided with a hook block 344 protruding from the outer peripheral wall of the water inlet portion 32 near the bottom end, and is matched with a hose limiting sheet 35, the hose limiting sheet 35 has a plate portion 351, a limiting insertion sheet 352 formed by extending and bending from the front end of the plate portion 351, and a positioning hook portion 353 formed by extending and bending from the rear end of the plate portion 351, and the positioning hook portion 353 is provided with a hook hole 354 for hooking and positioning the hook block 344; two sets of catch grooves 355 are formed on the plate body part 351 and can be respectively nested and positioned on the opposite peripheral walls of the cold water inlet pipe 41 and the hot water inlet pipe 42 of the water inlet pipe group 40; this spacing inserted sheet 352 has a spacing groove 356, can supply nested in the hose 65 is close to this water supply connector 63 a's periphery wall, supports simultaneously this water supply connector 63 a's lateral wall 63b, so, can prevent this water supply connector 63a to break away from this mixed water delivery port 313, and then solves this interior outlet pipe 60a and adopts hose 65 probably causes the unable firm problem of equipment.

In this embodiment, the inner water outlet pipe 60a is assembled by three pieces, namely, the water inlet joint 63a, the water outlet head 64a and the hose 65, and compared with the inner water outlet pipe 60 integrally molded by plastic material in the first embodiment, the inner water outlet pipe has to be molded by multiple times in a sectional manner, so that the production and manufacturing are easier and faster, and a higher product yield can be obtained, so the production and manufacturing cost is lower.

In this embodiment, two protruding columns 23 are protruded on the inner wall of the slot at the boundary between the longitudinal housing cover 21 and the upper housing half 22 of the upper housing cover 20, as shown in fig. 22, and a screw hole 231 is respectively disposed on the protruding columns 23. Two fastening bolts 24 are further provided and are respectively screwed with the screw holes 231 of the protruding columns 23, and a portion of the head portion 241 is pressed against the edge of the plate portion 351, so as to effectively prevent the hose limiting piece 35 from separating from the bottom of the inner body 30 a.

While the present invention has been described in detail and with reference to the embodiments thereof, it will be apparent to one skilled in the art that various alternatives and modifications can be made in accordance with the above description; accordingly, all such alternatives and modifications as may be devised based on the disclosure herein are intended to be included within the spirit and scope of the present claims.
