When the valve is in the closed position, the communication between the water inlet hole 131 and the first water outlet hole 132 and the communication between the water inlet hole 131 and the second water outlet hole 133 can be blocked respectively, so that the cold water from the cold water inlet pipe 20 is completely blocked by the valve core 50; in the cold water position, only the water inlet hole 131 is allowed to communicate with the second water outlet hole 133, so that the cold water from the cold water inlet pipe 20 through the cold water inlet channel 101 can be controlled to flow to the second water outlet hole 133, and then flow to the water outlet channel 42 through the mixing chamber 400, thereby forming cold water outlet; in the hot water position, only the water inlet hole 131 is allowed to communicate with the first water outlet hole 132, so that the cold water from the cold water inlet pipe 20 via the cold water inlet channel 101 can be controlled to flow to the first water outlet hole 132, then flow to the heater 32 via the cold water outlet channel 102 and the cold water outlet pipe 31 for heating to form hot water, and then flow to the mixing chamber 400 via the hot water inlet pipe 33 and the hot water inlet channel 103, and then flow to the water outlet channel 42 to form hot water outlet; in the mixed water position, the inlet hole 131 is allowed to be communicated with the first outlet hole 132 and the second outlet hole 133 at the same time, so that the cold water from the cold water inlet pipe 20 through the cold water inlet channel 101 is controlled to flow to the second outlet hole 133 and the first outlet hole 132 respectively, and a cold water and a hot water respectively flow into and converge in the mixing chamber 400 to mix the cold water and the hot water, and then flow to the outlet flow channel 42 to form a mixed water outlet.

In the present embodiment, the operating handle 60 can be pulled up and down within a predetermined angle range, can be pulled down within a predetermined angle range, and can be in a closed position when it is pulled down and positioned in an open position when it is pulled up and positioned in an open position, and can be pulled left and right within a predetermined angle range, for example, can be in a hot water position when it is pulled to the leftmost side, can be in a cold water position when it is pulled to the rightmost side, and can be in a mixed water position when it is pulled to the middle, and as for the mixed ratio of cold and hot water, the mixed ratio determines the temperature of the mixed water when it is viewed from the end near the left or right side. In addition, the amount of the discharged water, whether it is cold water, hot water or mixed water, can be determined by the angle of the operating handle 60 pulled upward, i.e., the opening amount. It should be noted that the operation of controlling the water flow and adjusting the mixing ratio of the cold water and the hot water by operating the handle 60 and linking the valve core 50 belongs to the prior art, and is not the key point of the present application, and therefore, it is not described herein in detail.

In the present embodiment, as shown in fig. 2 and 5, the outer casing 40 has a cylindrical portion 40a, and a water outlet pipe portion 40b extending from the outer peripheral wall of the cylindrical portion 40 a; a mounting chamber 41 is formed in the cylindrical portion 40 a; a water outlet flow passage 42 is formed in the water outlet pipe portion 40b, a water spray opening 421 is formed at the water outlet end of the water outlet flow passage 42, and a communication opening 43 is formed on the outer peripheral wall of the cylindrical portion 40a and is communicated with the water inlet end of the water outlet flow passage 42. The water jet 421 of the present embodiment is also provided with a water wave device 44.

In the present embodiment, as shown in fig. 3 and 5, the first oil seal 15 and the second oil seal 16 are respectively nested on the outer peripheral wall of the inner body 10 at the upper and lower sides relative to the mixing chamber 400 for abutting against and sealing the opposite inner peripheral wall of the mounting chamber 41, so as to prevent the cold water, the hot water or the mixed water entering the mixing chamber 400 from leaking outwards.

In the present embodiment, the outer peripheral wall of the inner body 10 is nested with the packing ring 17 above the third oil seal 15 for packing against the opposite inner peripheral wall of the mounting chamber 41, so that the outer housing 40 can keep rotating relative to the inner body 10 under a predetermined resistance, thereby ensuring that the outer housing 40 has good rotating tightness and feel.

The faucet 1 of the present embodiment further includes a fixing device 70, as shown in fig. 3 to 5, the fixing device 70 includes a screw 71, a packing nut 72, a packing assembly 73, and a metal fixing member 74 that can be inserted and positioned on the inner body 10 from the side; the table top 2 is provided with a mounting hole 2 a; the top end of the screw rod 71 can be connected with the metal fixing piece 74 after passing through the tightening component 73 and the mounting hole 2 a; the tightening nut 72 can be screwed on the screw rod 71, and the tightening assembly 73 is pressed against the bottom wall surface 2b of the table top 2 around the mounting hole 2a, so as to press and fix the bottom of the inner body 10 on the table top 2. Because the faucet 1 is directly attached to the table top 2 by the bottom of the inner body 10, a base is not needed, the number of components can be effectively reduced, the overall structure is simplified, and the production and manufacturing cost is reduced.

In the present embodiment, as shown in fig. 4, 5 and 7, the metal fixing member 74 is a screw member; the inner body 10 has a positioning groove 124 formed in a lateral direction thereof near the bottom end 12, so that the metal fixing member 74 can be inserted into the positioning groove 124 in a limited rotation manner, and the bottom end 12 of the inner body 10 has a rod groove 125 formed therethrough and communicating with the positioning groove 124, so that the top end of the screw rod 71 can be screwed with the metal fixing member 74 through the rod groove 125.

It should be noted that, because the inner body 10 can be integrally formed by plastic material, and because the structural strength of the plastic material itself is lower than that of the metal material, if a screw hole is directly formed on the inner body 10 to replace the metal fixing member 74, when a user screws the screw rod 71 into the screw hole, or screws the fastening nut 72 into the screw rod 71, so that the fastening component 73 abuts against and fastens the bottom wall surface 2b of the tabletop 2, the screw hole may be broken and damaged once the force is applied excessively, so that the above-mentioned problems can be effectively solved by using the nesting design of the metal fixing member 74.

It can be easily understood that the metal fixing member 74 is not limited to the above-mentioned screw member, but can also be an engaging member, so that the engaging member can be inserted into and positioned in the positioning groove 124 in a rotation-limited manner, so that the top end of the screw rod 71 can be engaged with the engaging member via the rod groove 125, and the above-mentioned problem can be solved effectively.

In the present embodiment, as shown in fig. 10 to 12, the tightening assembly 73 includes a tightening seat 73a and two spacers 73 b; the pressing seat 73a has a penetrating hole 731, an upper surface 732 and a lower surface 733, the penetrating hole 731 is used for the cold water inlet pipe 20, the cold water outlet pipe 31, the hot water inlet pipe 33 and the screw 71 to pass through, a gasket mounting groove 734 is respectively formed around the penetrating hole 731 on the upper surface 732 and the lower surface 733, a pressing part 735 is formed around the penetrating hole 731 on the pressing seat 73a to abut against the bottom wall surface 2b of the table top 2 around the mounting hole 2 a; the two gaskets 73b are respectively embedded and positioned in the gasket mounting groove 734, and are respectively formed with a through hole 736 and a concave portion 737, the through hole 736 is used for the screw rod 71 to pass through, the gasket 73b can avoid the cold water inlet pipe 20, the cold water outlet pipe 31 and the hot water inlet pipe 33 by the concave portion 737, the gasket 73b positioned above can be used for abutting against the bottom wall surface 2b tightly surrounding the mounting hole 2a, and the gasket 73b positioned below can be abutted against and tightly pressed by the pressing nut 72.

In this embodiment, as shown in fig. 3 and 5, the first water inlet 121, the water outlet 122 and the second water inlet 123 of the inner body 10 are respectively provided with a metal screwing member 18, which can be screwed and fixed to opposite ends of the cold water inlet pipe 20, the cold water outlet pipe 31 and the hot water inlet pipe 33, and the metal screwing member 18 can be pre-embedded to be coated on the first water inlet 121, the water outlet 122 and the second water inlet 123 by plastic injection, so as to ensure structural strength of screwing and avoid damage in screwing process, compared with a screwing structure directly forming a screw hole on the inner body 10.

In the embodiment, a limiting ring groove 19 is concavely arranged on the outer peripheral wall of the inner body 10 near the bottom end part 12; the cylindrical portion 40a of the outer housing 40 is provided with a screw hole 45, as shown in fig. 13, a limit bolt 46 can be screwed, and the end of the limit bolt 46 can be inserted into the limit ring groove 19, as shown in fig. 5, so that the outer housing 40 can be axially and movably sleeved outside the inner body 10 in a limited manner to rotate around the whole circumference or within a predetermined angle range, and can be rotated by a user according to the use requirement.

In this embodiment, a pressure reducing valve may be further installed in the cold water inlet pipe 20 to reduce the pressure of the cold water entering the heater 32, so as to prevent the heater 32 from being damaged or the service life of the heater 32 from being reduced due to high water pressure.

In order to prevent the hot water entering the mixing chamber 400 from being directly thermally conducted from the inner peripheral wall of the outer casing 40 to the outer peripheral wall thereof, which may cause a user to be inadvertently burned, the inner body 10 may be locally provided with an insulating member 80, such as an insulating collar, at either the outer peripheral wall of the mixing chamber 400 or the inner peripheral wall of the mounting chamber 41 of the outer casing 40 relative to the mixing chamber 400, as shown in fig. 14, so as to appropriately block the heat conduction and further reduce the temperature of the outer peripheral wall of the outer casing 40 close to the mixing chamber 400, thereby preventing the user from being inadvertently burned during the operation.

As can be seen from the above description, the faucet 1 of the present application has the following main features and advantages:

Secondly, by installing a pressure reducing valve in the cold water inlet pipe 20, the pressure of the cold water entering the heater 32 can be reduced, so as to prevent the heater 32 from being damaged or the service life of the heater 32 from being reduced due to high water pressure.

Thirdly, a mixing chamber 400 for mixing cold and hot water may be formed at a portion other than the valve core 50 by using a special channel and pipe design, so as to prevent the valve core 50 from directly contacting the hot water, thereby prolonging the service life of the valve core 50.

Fourthly, the fixing strength and firmness of the fixing device 70 can be ensured by the design of the additional metal fixing piece 74; similarly, the strength and firmness of the screw connection between each pipe fitting and the inner body 10 can be ensured by utilizing the design of the pre-embedded metal screw connection piece 18.

Fifthly, the design that the bottom of the inner body 10 is directly fixed on the table top 2 is utilized, so that the design of a base can be omitted, the structure is simplified, and the cost is reduced; by utilizing the design of the packing ring 17, the outer shell 40 can be ensured to have good rotating hand feeling; by using the design of the limit bolt 46 and the limit ring groove 19, the outer housing 40 can be axially limited in the inner body 10, and can rotate in a full circle or within a predetermined angle range, so that a user can rotate and position the outer housing 40 as desired to change the angular position of the water outlet.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
