Example two

As shown in fig. 9 to 13, the present invention provides a second embodiment of a dual-grip faucet. As shown in fig. 1 and 9, the double-handle faucet 1a according to the second embodiment is substantially the same as the double-handle faucet 1 according to the first embodiment. The main differences between the present embodiment and the first embodiment are:

as shown in fig. 9 to 11, in the present embodiment, the communication opening 223 is formed on both the bonding surfaces 221 of the inner body 20 a. The communication port 223 can communicate the water inlet 43 arranged at the bottom of the mixing valve core 40 with the cold water inlet channel 23 or the hot water inlet channel 24; the outer peripheral wall of the mixing valve core 40 is provided with at least one water outlet 44, and an annular communication chamber 101 defined between the outer peripheral wall of the mixing valve core 40 and the inner peripheral wall of the corresponding sealing sleeve 30 is communicated with the water outlet 44. The inner body 20a is provided with two communication channels 103, and the communication channels 103 are communicated with the mixed water outlet flow channel 25 and the corresponding communication cavity 101; the communication port 223, the annular communication chamber 101, and the communication channel 103 together form a water passage 100. As shown in fig. 5 and 10, it can be understood that the communication channel 103 provided in the inner body 20a and the communication channel 102 provided in the inner body 20 are slightly different in configuration and arrangement position.

As can be seen from the above, in the present embodiment, the cold water and the hot water respectively flowing from the cold water inlet channel 23 and the hot water inlet channel 24 both mainly flow through the corresponding communication ports 223, then flow through the water inlets 43 at the bottom of the corresponding mixing valve core 40 to enter the mixing valve core 40, and then flow into the communication chamber 101 from the water outlets 44 around the mixing valve core 40.

It can be understood that the cold water and the hot water in the first embodiment enter from the surrounding water inlets of the corresponding mixing valve cores and then flow out from the water outlet at the bottom. As shown in fig. 9, the flow paths of the cold water and the hot water are just opposite, that is, the mixing valve core 40 is bottom water inlet and surrounding water outlet. Although the flow path design and the flow path are slightly different, the water flow path 100 is formed among the mounting valve spool 22, the seal sleeve 30, and the mixing valve body 40, and the water flow path 100 is controlled by the mixing valve body 40.

Alternatively, in the present embodiment, the inner body 20a is an inner body made of plastic. It should be noted that it is necessary to provide a corresponding structure for molding the internal water path of the inner body 20a, particularly the transverse extension of the communication channel 103, by plastic molding so that it communicates with the longitudinal extension of the channel 103 and with the mixed water outlet channel 25. As shown in fig. 11 and 12, alternatively, in the present embodiment, the inner body 20a forms a notch 200 at the outer peripheral wall 21 of the transverse extension of the communication channel 103, and the plug 201 is sealingly embedded at the notch 200. It will be appreciated that the notch 200 facilitates the opening of the mould to form the lateral extension of the communication channel 103; the plug 201 is sealed and inserted in the gap 200, so that the problem of mold opening forming can be solved. Optionally, in this embodiment, the outer circumferential wall of the plug 201 is embedded with a sealing gasket 202 to achieve an embedding sealing effect.

EXAMPLE III

As shown in fig. 14 to 16, the present invention provides a third embodiment of a dual-grip faucet. The water flow passage 100 of the double-handled faucet 1b according to the third embodiment is substantially the same as that of the second embodiment. That is, the paths of the cold water and the hot water flowing along the water flow passage 100 to the mixed water outlet passage 25 in the present embodiment are substantially the same as those in the second embodiment, and the main difference between the present embodiment and the second embodiment is that:

the dual-handle faucet 1b of the present embodiment is a dual-function faucet, i.e., has both faucet water output and spray gun water output functions, so that a common spray gun assembly is provided, which is different from the pull-out faucet of the first and second embodiments.

Further, as shown in fig. 14 to 16, the mixed water outlet flow passage 25a of the present embodiment is slightly different from the mixed water outlet flow passages of the first and second embodiments. Specifically, the mixed water outlet passage 25a includes a mounting chamber 251 and a gun passage 252 communicating with the mounting chamber 251. Wherein, the mounting chamber 251 is respectively communicated with the corresponding communicating chambers 101 through two communicating channels 103. Further, a water divider 253 is installed inside the installation chamber 251, and the water divider 253 has at least one water inlet 254, at least one faucet water outlet 255, and a gun water outlet 256. Wherein the water inlet 254 is communicated with both the two communication channels 103; the faucet water outlet 255 is rotatably mounted at the water outlet elbow 17; the lance outlet 256 communicates with the lance flow passage 252. Further, the water separator 253 can separate the cold water and the hot water from the two communication channels 103 to the faucet water outlet 255 or the gun water outlet 256 according to the water pressure. Further, a lance connection port 257 is formed at the bottom end of the lance flow passage 252, and the lance connection port 257 is connected with a lance connection pipe 258. It will be appreciated that the lance connection tube 258 can be used for assembly connection of the lance assembly. The water distributor 253 and the spray gun assembly are conventional structures, and therefore are not described herein.

Example four

As shown in fig. 17, the present invention provides a fourth embodiment of a two-handle faucet. As shown in fig. 14 and 17, the two-handle faucet 1c of the present embodiment is substantially the same as the two-handle faucet 1b of the third embodiment. The main difference between this embodiment and the third embodiment is:

as shown in fig. 17, the dual-handle water tap 1c of the present embodiment does not have a spray gun assembly, so that the water diversion function of the third embodiment is not required, and it is not necessary to install a water diverter in the installation chamber 251 of the inner body 20 b. Meanwhile, the spray gun connection port does not need to be connected with the spray gun connection pipe, but in order to prevent the mixed water entering the installation cavity 251 from flowing to the spray gun connection port, a mold core can be inserted into the mold, so that a closed wall 259 is integrally formed between the spray gun flow passage 252 of the inner body 20b and the installation cavity 251 through plastic molding and is isolated and blocked from each other.

As can be seen from the above, the inner bodies 20, 20a, 20b of the above embodiments are all cylindrical and are coaxially mounted with the corresponding body 10; the cold water inlet flow channel, the hot water inlet flow channel and the mixed water outlet flow channel of the inner bodies 20, 20a and 20b are all designed to extend longitudinally; meanwhile, a water flowing channel formed by the installation valve groove, the sealing sleeve and the mixing valve core is skillfully utilized to communicate the corresponding cold water inlet channel, the hot water inlet channel and the mixed water outlet channel. Therefore, the whole flow channel planning and configuration is quite ingenious and simple, and enough volume and space are reserved for arranging the guide holes, so that the situation that the known inner body needs to be eccentrically configured is avoided, the symmetry and the attractiveness of the whole appearance can be ensured, meanwhile, a tiny gap is allowed to exist between the inner bodies 20, 20a and 20b and the corresponding outer bodies, the diameters of the corresponding outer bodies are greatly reduced, the material cost can be reduced, and the attractiveness can be improved.

As mentioned above, there is sufficient space within the inner body 20, 20a, 20b to design the corresponding guide holes. Therefore, the drawing hose penetrating the corresponding guide hole can obtain the best guiding sliding effect, thereby ensuring that the drawing and resetting of the sprinkler head are smoother.

While the utility model has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various alternatives and modifications can be made therein in light of the above teachings; 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.

The above are merely examples of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art to which the present application pertains. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
