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, 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 view of this, how to avoid obvious fluctuations in the water outlet temperature of the H-shaped faucet body is a technical problem that needs to be solved by technical personnel in this field. Utility Model Content

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] 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.

[0032] 2. A flow baffle is provided in the mixing chamber between the left inlet and the right inlet of the mixing chamber, so as to block the water flow entering the left inlet of the mixing chamber and the water flow entering the right inlet of the mixing chamber from forming a collision. 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 with each other 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 with the water flow with lower water pressure (hot water flow) in the opposite direction as in the prior art and force the water flow with lower water pressure to flow back, thereby effectively improving the problem of obvious fluctuation of 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 outlet of the mixing chamber is connected to a water outlet terminal with a larger pipe resistance (such as a water outlet nozzle with a bubbler), the baffle of the present solution is used to avoid the cold and hot water from directly colliding in opposite directions, which can have a particularly obvious effect of reducing the phenomenon of cold water pressing on hot water.

[0054] 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.

[0055] For the convenience of description, the front, rear, left, right, top and bottom directions of the present invention are shown in FIG. Figure 1 , Figure 2 and Fig. 9 The orientation diagram shown in .

[0056] See also Figures 1 to 4 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.

[0057] 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.

[0058] A flow blocking member 34 is provided in the mixing chamber 33 between the left inlet 331 and the right inlet 332 of the mixing chamber, so as to block the water flow entering the left inlet 331 and the water flow entering the right inlet 332 of the mixing chamber through the flow blocking member 34 to form a counteraction. Figure 4The dotted arrows are used to indicate the water flow path. 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 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 in the opposite direction with the water flow with lower water pressure (hot water flow) 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 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 333 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 baffle 34 of this solution is used to avoid the cold and hot water from directly colliding in opposite directions, which can have a particularly obvious effect of reducing the phenomenon of cold water pressing hot water.

[0059] In this embodiment, preferably, the projection of the baffle 34 at the left inlet 331 of the mixing chamber along the axial direction of the left inlet 331 of the mixing chamber covers the left inlet 331 of the mixing chamber; the projection of the baffle 34 at the right inlet 332 of the mixing chamber along the axial direction of the right inlet 332 of the mixing chamber covers the right inlet 332 of the mixing chamber. With this design, the blocking effect of the baffle 34 is better, and the water flow can be basically blocked. If the projection of the baffle 34 at the left inlet 331 of the mixing chamber along the axial direction of the left inlet 331 of the mixing chamber does not completely cover the left inlet 331 of the mixing chamber, or the projection of the baffle 34 at the right inlet 332 of the mixing chamber along the axial direction of the right inlet 332 of the mixing chamber does not completely cover the right inlet 332 of the mixing chamber, the baffle 34 may not be able to block the water flow flowing out of the uncovered part. Although it also has a blocking effect, the blocking effect is poor.

[0060] In this embodiment, preferably, the mixing chamber outlet 333 is opened at the top of the mixing chamber 33, the mixing chamber left inlet 331 and the mixing chamber right inlet 332 are arranged relatively to each other, and the axes of the mixing chamber left inlet 331 and the mixing chamber right inlet 332 coincide with each other. Of course, in other embodiments, the axes of the mixing chamber left inlet 331 and the mixing chamber right inlet 332 do not necessarily coincide, and the two may also be parallel or intersecting to a certain extent.

[0061] In this embodiment, preferably, the baffle 34 is a baffle 34, and the baffle 34 is formed by vertically extending upward from the bottom wall of the mixing chamber 33. Preferably, the baffle 34 is vertically extended upward from the bottom wall of the mixing chamber 33 to at least above the top of the left inlet 331 of the mixing chamber and the top of the right inlet 332 of the mixing chamber, so that the baffle 34 has a better effect of blocking the water flow collision of the two inlets of the mixing chamber 33. The top of the baffle 34 can extend to the position of the mixing chamber outlet 333, or it can be lower than the position of the mixing chamber outlet 333.

[0062] In this embodiment, preferably, one baffle 34 is provided, and both ends of the baffle 34 have flow gaps with the inner circumferential wall of the mixing chamber 33. Figure 4 The cross section of the baffle 34 is in the shape of a straight line.

[0063] In this embodiment, the baffle 34 is centrally disposed between the left inlet 331 of the mixing chamber and the right inlet 332 of the mixing chamber. Of course, in some other embodiments, the baffle 34 may be disposed closer to the one with a higher water pressure between the left inlet 331 and the right inlet 332 of the mixing chamber, so that the baffle 34 can more effectively block the water flow with a higher water pressure, thereby making the two water flows mix more evenly. For example, when the left inlet 331 of the mixing chamber is used to provide cold water with a higher water pressure, and the right inlet 332 of the mixing chamber is used to provide hot water with a lower water pressure, it is preferred that the baffle 34 be disposed closer to the left inlet 331 of the mixing chamber.

[0064] In this embodiment, 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. In addition, no molding processing holes due to molding the left channel 31 and the right channel 32 will be formed on the faucet body 1, and there is no need to seal the molding processing holes. The sealing and strength of the entire faucet body 1 are better, and the manufacturing is simpler.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] In this embodiment, the baffle 34 is integrally formed in the mixing chamber 33. In other embodiments, the baffle 34 can also be formed separately and then fixedly connected in the mixing chamber 33 by common fixed connection methods such as clamping, bonding or welding.

[0069] See also Figure 5The second embodiment of the utility model provides a faucet body 1, which is mainly different from the first embodiment in that: in the first embodiment, the cross section of the baffle 34 is a straight line; while in the present embodiment, the cross section of the baffle 34 is similar to an S shape. The S-shaped shape can guide the water flow more smoothly, thereby achieving a better mixing effect of the two water flows.

[0070] See also Figure 6 The third embodiment of the faucet body 1 provided by the utility model is mainly different from the first embodiment in that: in the first embodiment, only one baffle 34 is provided. In the present embodiment, two baffles 34 are provided, namely a left baffle 341 and a right baffle 342.

[0071] See also Figure 6 , one end of the left baffle 341 is connected to the rear side of the left inlet 331 of the mixing chamber, and the other end extends toward the right inlet 332 of the mixing chamber; one end of the right baffle 342 is connected to the front side of the right inlet 332 of the mixing chamber, and the other end extends toward the left inlet 331 of the mixing chamber; the left baffle 341 is used to guide the water flow entering the left inlet 331 of the mixing chamber toward the inner wall of one side of the mixing chamber 33; the right baffle 342 is used to guide the water flow entering the right inlet 332 of the mixing chamber toward the inner wall of the other side of the mixing chamber 33. Of course, it can also be replaced by: one end of the left baffle 341 is connected to the front side of the left inlet 331 of the mixing chamber, and the other end extends toward the right inlet 332 of the mixing chamber; one end of the right baffle 342 is connected to the rear side of the right inlet 332 of the mixing chamber, and the other end extends toward the left inlet 331 of the mixing chamber.

[0072] In this embodiment, the projection of the left baffle 341 at the mixing chamber left inlet 331 along the axis direction of the mixing chamber left inlet 331 covers the mixing chamber left inlet 331; the projection of the right baffle 342 at the mixing chamber right inlet 332 along the axis direction of the mixing chamber right inlet 332 covers the mixing chamber right inlet 332. This design can more fully block the water flow and achieve a better blocking effect.

[0073] In this embodiment, the left baffle 341 and the right baffle 342 are not only integrally connected to the bottom wall of the mixing chamber 33, but also integrally connected to the inner wall of the mixing chamber 33, so that the baffles have better strength and are easier to shape.

[0074] See also Figure 7The fourth embodiment of the faucet body 1 provided by the utility model is mainly different from the third embodiment in that: in the third embodiment, the projection of the left baffle 341 at the left inlet 331 of the mixing chamber along the axis direction of the left inlet 331 of the mixing chamber covers the left inlet 331 of the mixing chamber; the projection of the right baffle 342 at the right inlet 332 of the mixing chamber along the axis direction of the right inlet 332 of the mixing chamber covers the right inlet 332 of the mixing chamber. In addition, one end of the left baffle 341 is connected to the rear side of the left inlet 331 of the mixing chamber, and one end of the right baffle 342 is connected to the front side of the right inlet 332 of the mixing chamber.

[0075] In this embodiment, the projection of the left baffle 341 at the mixing chamber left inlet 331 along the axis direction of the mixing chamber left inlet 331 covers half of the mixing chamber left inlet 331, and the projection of the right baffle 342 at the mixing chamber left inlet 331 along the axis direction of the mixing chamber left inlet 331 covers the other half of the mixing chamber left inlet 331; the projection of the left baffle 341 at the mixing chamber right inlet 332 along the axis direction of the mixing chamber right inlet 332 covers half of the mixing chamber right inlet 332, and the projection of the right baffle 342 at the mixing chamber right inlet 332 along the axis direction of the mixing chamber right inlet 332 covers the other half of the mixing chamber right inlet 332. In addition, one end of the left baffle 341 is connected to the front side of the mixing chamber left inlet 331, and the other end extends toward the mixing chamber right inlet 332, and one end of the right baffle 342 is connected to the rear side of the mixing chamber right inlet 332, and the other end extends toward the mixing chamber left inlet 331.

[0076] Similarly, in this embodiment, the left baffle 341 and the right baffle 342 are not only integrally connected to the bottom wall of the mixing chamber 33, but also integrally connected to the inner wall of the mixing chamber 33, so that the baffles have better strength and are easier to shape.

[0077] See also Figure 8 The fifth embodiment of the utility model provides a faucet body 1, which is mainly different from the first embodiment in that: in the first embodiment, the baffle 34 is only a simple straight cross section. In this embodiment, the baffle 34 and the inner wall of the mixing chamber 33 form a venturi channel 35, and the flow cross-sectional area of ​​the venturi channel 35 gradually decreases along the water flow direction. The venturi channel 35 is used to guide the water flow entering from one of the left inlet 331 and the right inlet 332 of the mixing chamber to the other of the two and generate a venturi effect at the other of the two to suck the water flow of the other of the two.

[0078] Specifically, in this embodiment, the water flow entering the right inlet 332 of the mixing chamber is selected to be cold water with a relatively high water pressure, and the water flow entering the left inlet 331 of the mixing chamber is selected to be hot water with a relatively low water pressure. The cold water flow at the right inlet 332 of the mixing chamber forms a Venturi effect after passing through the Venturi channel 35 to suck the hot water flow at the left inlet 331 of the mixing chamber, thereby promoting the hot water at the left inlet 331 of the mixing chamber to enter the mixing chamber. This solution is particularly suitable for the case where a solar water heater is used to provide hot water to a faucet, and even if the hot water pressure is relatively low, it can stably and reliably flow into the mixing chamber 33.

[0079] In this embodiment, the portion of the venturi channel 35 corresponding to the left inlet 331 of the mixing chamber guides the water flow to flow through the left inlet 331 of the mixing chamber along the circumference of the mixing chamber 33. This can make the venturi effect more obvious and the suction effect of hot water better.

[0080] In this embodiment, the baffle 34 is located on one side of the Venturi channel 35 and is a smoothly transitioned arc surface 343, and the arc surface 343 gradually approaches the inner wall of the mixing chamber 33 along the water flow direction. Specifically, the arc surface is a U-shaped surface, and the Venturi channel 35 is a U-shaped channel.

[0081] More preferably, in this embodiment, the baffle 34 also forms a drainage channel 36 with the inner wall of the mixing chamber 33, and the drainage channel 36 connects the right inlet 332 of the mixing chamber and the Venturi channel 35, and the water flow at the right inlet 332 of the mixing chamber is drained to the Venturi channel 35 through the drainage channel 36.

[0082] It is understandable that in other embodiments, it can also be replaced by: the water flow entering the left inlet 331 of the mixing chamber is selected to be cold water with a relatively large water pressure, and the water flow entering the right inlet 332 of the mixing chamber is selected to be hot water with a relatively small water pressure, and the cold water flow at the left inlet 331 of the mixing chamber forms a Venturi effect after passing through the Venturi channel 35 to suck the hot water flow at the right inlet 332 of the mixing chamber, thereby promoting the hot water at the right inlet 332 of the mixing chamber to enter the mixing chamber 33. Correspondingly, the drainage channel 36 connects the left inlet 331 of the mixing chamber with the Venturi channel 35.

[0083] See also Fig. 9 and Fig.10 The sixth embodiment of the utility model provides a faucet, comprising an H-shaped faucet body 1, a left valve core 2, and a right valve core 3. The faucet body 1 is the faucet body 1 described in any of the above embodiments. The left valve core 2 is disposed in the left valve chamber 11, the right valve core 3 is disposed in the right valve chamber 21, the left valve chamber inlet 112 is connected to a hot water source, the right valve chamber inlet 212 is connected to a cold water source, and the mixing chamber outlet 333 is connected to a curved water outlet pipe 4. The left valve core 2 and the right valve core 3 can adopt existing known structures. The left valve core 2 is used to control the on-off between the left valve chamber inlet 112 and the left valve chamber outlet 113, and the right valve core 3 controls the on-off between the right valve chamber inlet 212 and the right valve chamber outlet 213.
