Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet body and a faucet with the faucet body. Background Art

[0002] In the prior art, for example, a Chinese utility model patent with a publication number of CN203594847U discloses a plastic water regulating rack, which has an H-shaped appearance, a "concave"-shaped inner core of a high-fluidity plastic and an H-shaped outer shell of a rigid plastic; the inner core has a horizontal tube and two tubular valve seats extending upward, the middle section of the horizontal tube is provided with an outwardly leading water outlet, and the two ends of the horizontal tube are respectively connected to a valve seat, and the inner hole of the horizontal tube connects its water outlet with the inner cavity of the two valve seats at its two ends; a water inlet is provided at the bottom of each valve seat; a horizontal sleeve is provided in the middle of the outer shell to wrap around the horizontal tube of the inner core and lead its water outlet outward, and vertical tubes are respectively provided at both ends of the horizontal sleeve to wrap around the corresponding valve seats on the inner core, the outer periphery of the upper opening of each vertical pipe is provided with an external thread, and a water inlet pipe with an external thread on the outer periphery extends downward from the lower end of each vertical pipe; each water inlet pipe is connected to the water inlet of the corresponding valve seat of the inner core.

[0003] In the above prior art, the left inner hole 201 of the transverse tube 20 connects the inner hole 211 of the water outlet 21 with the inner cavity 221 of the left end valve seat 22, and the right inner hole 201 of the transverse tube 20 connects the inner hole 211 of the water outlet 21 with the inner cavity 241 of the right end valve seat 24. However, there is no mixing chamber between the left inner hole 201 and the right inner hole 201, and the water outlet end of the left inner hole 201 is directly connected with the water outlet end of the right inner hole 201, so that the water flow from the left end valve seat 22 and the water flow from the right end valve seat 24 directly collide with each other and then flow out of the water outlet 21. Under normal use, cold water enters one of the left valve seat 22 and the right valve seat 24, and hot water enters the other. On the one hand, the direct impact of the cold and hot water flows will cause uneven water mixing, which is not conducive to the stability of the outlet water temperature. On the other hand, the hot water flow generally has a lower water pressure after passing through the heater (especially the solar water heater), while the cold water flow has a higher water pressure. The direct impact of cold water and hot water may cause the hot water to be pressed back by the cold water, and the outlet water temperature may fluctuate significantly due to the instability of the cold water pressure.

[0004] In addition, in the above-mentioned prior art, the plastic water regulating rack needs to be formed by gas-assisted injection molding and secondary injection molding plus a small amount of mechanical processing. The molding process is relatively complicated and the manufacturing cost is still high.

[0005] In view of this, how to avoid obvious fluctuations in the water outlet temperature of the H-shaped faucet body and how to simplify its molding process are technical problems that need to be solved by technical personnel in this field. Utility Model Content

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] 1. The utility model provides a left channel, a right channel, and a mixing chamber between the left channel and the right channel in a horizontal pipe. The mixing chamber is provided with a left inlet, a right inlet, and an outlet. The left channel is connected to the left valve chamber outlet and the left inlet of the mixing chamber, and the right channel is connected to the right valve chamber outlet and the right inlet of the mixing chamber. Thus, by providing the mixing chamber, the water flow of the left channel and the water flow of the right channel will not collide with each other in opposite directions and then directly flow out of the water outlet as in the prior art (CN203594847U), but will flow into the mixing chamber, mix in the mixing chamber, and then flow out of the water outlet. For the mixing of cold and hot water, the stability of the outlet water temperature is beneficial.

[0027] 2. The plane P1 where the axis of the left channel is located is not coplanar with the plane P2 where the axis of the right channel is located. With this design, when the water in the two channels is mixed, the water flows in the left channel and the right channel will not directly collide in opposite directions, thereby having the following beneficial effects: on the one hand, the water flows in the left channel and the right channel can enter the mixing chamber and achieve stable mixing in the mixing chamber regardless of the water pressure; on the other hand, the water flow with higher water pressure (cold water flow) will not directly collide in the opposite direction with the water flow with lower water pressure (hot water flow) as in the prior art and force the water flow with lower water pressure to flow back, thereby effectively improving the problem of obvious fluctuations in the outlet water temperature due to the instability of the cold water pressure (i.e., higher water pressure), which is conducive to more uniform mixing of cold and hot water. In particular, when the outlet of the mixing chamber is connected to a water outlet terminal with a large pipe resistance (such as a water outlet with a bubbler), the plane P1 of this solution is not coplanar with the plane P2 to avoid direct collision of cold and hot water in opposite directions, which can have a particularly obvious effect of reducing the phenomenon of cold water pressing hot water;

[0028] 3. The left water inlet seat, the right water inlet seat and the cross tube are integrally injection molded. The left channel and the right channel are arc-shaped channels and can be formed by injection molding core pulling. The mold core used to form the left channel can be pulled out through the top opening of the left valve cavity, and the mold core used to form the right channel can be pulled out through the top opening of the right valve cavity. With this design, the left channel and the right channel can be formed by injection molding core pulling, which makes molding easier, and no molding holes due to molding the left and right channels will be formed on the faucet body, and there is no need to seal the molding holes. The sealing and strength of the entire faucet body are better, and the manufacturing is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0058] For the convenience of description, the front, rear, left, right, top and bottom directions of the present invention are shown in FIG. Figure 1 , Fig.12 , Fig.13 and Fig.14 The orientation diagram shown in .

[0059] See also Figures 1 to 6 The utility model provides a faucet body 1 of the first embodiment, comprising a left water inlet seat 10, a right water inlet seat 20 and a transverse pipe 30. The left water inlet seat 10 and the right water inlet seat 20 are arranged side by side, and the transverse pipe 30 connects the left water inlet seat 10 and the right water inlet seat 20 in a transverse direction. A left valve cavity 11 is formed in the left water inlet seat 10, and a right valve cavity 21 is formed in the right water inlet seat 20. An opening 111 is formed at the top end of the left valve cavity 11, a left valve cavity inlet 112 is provided at the bottom end, and a left valve cavity outlet 113 is provided on the side wall. An opening 211 is formed at the top end of the right valve cavity 21, a right valve cavity inlet 212 is provided at the bottom end, and a right valve cavity outlet 213 is provided on the side wall.

[0060] The transverse pipe 30 is provided with a left channel 31, a right channel 32, and a mixing chamber 33 located between the left channel 31 and the right channel 32. The mixing chamber 33 is provided with a left mixing chamber inlet 331, a right mixing chamber inlet 332, and a mixing chamber outlet 333. The left channel 31 is connected with the left valve chamber outlet 113 and the left mixing chamber inlet 331, and the right channel 32 is connected with the right valve chamber outlet 213 and the right mixing chamber inlet 332, that is, the left valve chamber outlet 113 constitutes the water inlet end of the left channel 31, and the left mixing chamber inlet 331 constitutes the water outlet end of the left channel 31. Similarly, the right valve chamber outlet 213 constitutes the water inlet end of the right channel 32, and the right mixing chamber inlet 332 constitutes the water outlet end of the right channel 32. By setting up the mixing chamber 33, the water flows of the left channel 31 and the right channel 32 will not collide with each other in opposite directions and then directly flow out of the water outlet as in the prior art (CN203594847U), but will both flow into the mixing chamber 33, mix in the mixing chamber 33 and then flow out of the water outlet, which is beneficial to the stability of the outlet water temperature for mixing cold and hot water.

[0061] The left water inlet seat 10, the right water inlet seat 20 and the cross tube 30 are integrally injection molded, and the left channel 31 and the right channel 32 are both arc-shaped channels and can be formed by injection core pulling. The mold core used to form the left channel 31 can be pulled out through the top opening of the left valve cavity 11, and the mold core used to form the right channel 32 can be pulled out through the top opening of the right valve cavity 21. The design that the left channel 31 and the right channel 32 are both arc-shaped channels is adopted, so that the left channel 31 and the right channel 32 can be formed by injection core pulling, and molding is easier. There is no molding processing hole formed on the faucet body 1 due to molding the left channel 31 and the right channel 32, and there is no need to seal the molding processing hole. The sealing and strength of the entire faucet body 1 are better, and the manufacturing is simpler.

[0062] The plane P1 where the axis of the left channel 31 is located is not coplanar with the plane P2 where the axis of the right channel 32 is located. With this design, when the water in the two channels is mixed, the water flows in the left channel 31 and the right channel 32 will not directly collide with each other in opposite directions, thereby having the following beneficial effects: on the one hand, the water flows in the left channel 31 and the right channel 32 can enter the mixing chamber 33 and achieve stable mixing in the mixing chamber 33 regardless of the water pressure; on the other hand, the water flow with higher water pressure (cold water flow) will not directly collide with the water flow with lower water pressure (hot water flow) in the opposite direction as in the prior art to force the water flow with lower water pressure to flow back, thereby effectively improving the problem of obvious fluctuations in water outlet temperature due to the instability of cold water pressure (i.e., higher water pressure), which is conducive to more uniform mixing of cold and hot water. In particular, when the mixing chamber outlet 333 is connected to a water outlet terminal with a larger pipe resistance (such as a water outlet nozzle with a bubbler), the plane P1 and the plane P2 of the present solution are not coplanar to avoid the cold and hot water directly colliding in opposite directions, which can have a particularly obvious effect of reducing the phenomenon of cold water pressing on hot water.

[0063] Preferably, in this embodiment, the positions of the left inlet 331 of the mixing chamber and the right inlet 332 of the mixing chamber are staggered, and the positions of the two inlets of the mixing chamber 33 are staggered, so as to further ensure that the two streams of water entering the mixing chamber 33 will not directly collide with each other in opposite directions. Of course, it is necessary to explain that the positions of the left inlet 331 of the mixing chamber and the right inlet 332 of the mixing chamber can also be arranged without staggering, and can be located at the same position in both the vertical direction and the front-back direction. Since the plane P1 where the axis of the left channel 31 is located is not coplanar with the plane P2 where the axis of the right channel 32 is located, the water entry directions of the left inlet 331 of the mixing chamber and the right inlet 332 of the mixing chamber will inevitably not be opposite directions. In other words, even if the positions of the left inlet 331 of the mixing chamber and the right inlet 332 of the mixing chamber are not staggered, the water flows will not directly collide with each other in opposite directions. In specific implementation, the two inlets can also be not staggered, as long as the two streams of water entering the mixing chamber 33 will not directly collide with each other in opposite directions.

[0064] See also Figure 3 In this embodiment, the left inlet 331 and the right inlet 332 of the mixing chamber are completely staggered in the front-to-back direction. It can be understood that in other embodiments, the left inlet 331 and the right inlet 332 of the mixing chamber can also be partially staggered in the front-to-back direction, and / or the left inlet 331 and the right inlet 332 of the mixing chamber can also be partially staggered in the vertical direction or completely staggered. The direction in which the left inlet 331 and the right inlet 332 of the mixing chamber are staggered, and whether to adopt a partially staggered setting or a completely staggered setting can be selected according to needs, and there is no limitation on this.

[0065] The plane P1 where the axis of the left channel 31 is located and the plane P2 where the axis of the right channel 32 is located can intersect or be parallel, so that the two planes are not coplanar. Specifically, it can be set as follows: the left inlet 331 of the mixing chamber is located on the plane P2 where the axis of the right channel is located, and the left valve chamber outlet 113 is not on the plane P2 where the axis of the right channel is located; or, the left inlet 331 of the mixing chamber is not on the plane P2 where the axis of the right channel is located, and the left valve chamber outlet 113 is located on the plane P2 where the axis of the right channel is located; or, both the left inlet 331 of the mixing chamber and the left valve chamber outlet 113 are not on the plane P2 where the axis of the right channel is located; or,

[0066] It can also be set as follows: the right inlet 332 of the mixing chamber is located on the plane P1 where the axis of the left channel is located, and the right valve chamber outlet 213 is not on the plane P1 where the axis of the left channel is located; or, the right inlet 332 of the mixing chamber is not on the plane P1 where the axis of the left channel is located, and the right valve chamber outlet 213 is located on the plane P1 where the axis of the left channel is located; or, both the right inlet 332 of the mixing chamber and the right valve chamber outlet 213 are not on the plane P1 where the axis of the left channel is located.

[0067] In this embodiment, see Figure 4 The AA section is the plane P1 where the axis of the left channel 31 is located, and the BB section is the plane P2 where the axis of the right channel is located. The plane P1 where the axis of the left channel 31 is located is parallel to the plane P2 where the axis of the right channel 32 is located, so that the left inlet 331 of the mixing chamber and the left valve chamber outlet 113 are not on the plane P2 where the axis of the right channel is located, and similarly, the right inlet 332 of the mixing chamber and the right valve chamber outlet 213 are also not on the plane P1 where the axis of the left channel is located.

[0068] Preferably, the water flow entering the mixing chamber 33 from the left mixing chamber inlet 331 and the right mixing chamber inlet 332 forms a swirl along the inner circumferential wall of the mixing chamber 33, see Figure 3The arrow in the mixing chamber 33 shows the swirl direction of the water flow. More preferably, in this embodiment, the water flow entering the mixing chamber 33 from the left inlet 331 and the right inlet 332 enters along the tangent direction of the inner wall of the mixing chamber 33. The swirl mixing of the water flow in the mixing chamber 33 can make the water flow mixing more uniform and stable, which is more conducive to the stable control of the outlet water temperature.

[0069] In this embodiment, the left valve cavity 11 is cylindrical, and the plane P1 where the axis of the left channel 31 is located is coplanar with one of the planes passing through the axis of the left valve cavity 11; the right valve cavity 21 is cylindrical, and the plane P2 where the axis of the right channel 32 is located is coplanar with one of the planes passing through the axis of the right valve cavity 21. In this design, the water inlet end (left valve cavity outlet 113) of the left channel 31 is located on one of the planes passing through the axis of the left valve cavity 11 (i.e., the left valve cavity outlet 113 is in the diameter direction of the left valve cavity 11), and similarly, the water inlet end (right valve cavity outlet 213) of the right channel 32 is located on one of the planes passing through the axis of the right valve cavity 21 (i.e., the right valve cavity outlet 213 is in the diameter direction of the right valve cavity 21). When the left channel 31 and the right channel 32 are core-pulling by injection molding, the radial space of the left valve cavity 11 and the right valve cavity 21 can be utilized to the maximum extent, so that the core-pulling is easier and more reliable, and the radial dimensions of the left valve cavity 11 and the right valve cavity 21 can be designed to be smaller.

[0070] In this embodiment, the left valve chamber 11 and the right valve chamber 21 are both cylindrical, and the axis X3 of the mixing chamber outlet 333 is on a plane passing through the axis X1 of the left valve chamber 11 and the axis X2 of the right valve chamber 21, that is, the axis X3 of the mixing chamber outlet 333, the axis X1 of the left valve chamber 11 and the axis X2 of the right valve chamber 21 are on the same plane.

[0071] In this embodiment, a left water inlet pipe 40 is integrally formed at the inlet 112 of the left valve cavity, and a right water inlet pipe 50 is integrally formed at the inlet 212 of the right valve cavity. The left water inlet pipe 40 is coaxially arranged with the left valve cavity 11, and the right water inlet pipe 50 is coaxially arranged with the right valve cavity 21. The outer walls of the left water inlet pipe 40 and the right water inlet pipe 50 are both molded with an external thread sleeve 60 with an external thread, and the external thread sleeve 60 can be made of stainless steel, zinc alloy, aluminum, copper, etc. The strength of the external thread sleeve 60 is greater than the strength of the left water inlet pipe 40 and the right water inlet pipe 50. In other embodiments, the external thread sleeve 60 may not be provided, but the external thread may be directly integrally formed on the outer walls of the left water inlet pipe 40 and the right water inlet pipe 50.

[0072] In this embodiment, a water outlet connector 70 is integrally connected to the outlet 333 of the mixing chamber, that is, the water outlet connector 70 is integrally injection molded with the left water inlet seat 10, the right water inlet seat 20 and the transverse pipe 30. The axis of the water outlet connector 70 is parallel to the axis of the left water inlet pipe 40 and the right water inlet pipe 50. The outer wall of the water outlet connector 70 is provided with an external thread. In some other embodiments, the water outlet connector 70 can also be separately molded and connected to the outlet 333 of the mixing chamber by means of clamping, threaded connection or welding.
