Description

Technical Field

[0001] The invention belongs to the technical field of sanitary ware and relates to a faucet body, in particular to a faucet body in a pre-buried faucet assembly. Background Art

[0002] At present, with the pursuit of beauty and personalization, more and more people choose to use pre-buried wall-mounted faucets, that is, the main body of the faucet is buried in the wall, and only the handle and the water spout are exposed outside the wall, which looks simple and high-grade. For example, the patent application No. 201710256666.7 discloses a split-type wall-mounted basin faucet, which includes a pre-buried box body with a front opening, a spirit level, a faucet and a panel. The faucet includes a main body, a valve core assembly and a water spout. The panel is provided with a valve assembly hole and a water spout fixing hole. The front opening of the pre-buried box is provided with a sleeve with selectable length, and the front opening of the sleeve is provided with a detachable cover. The main body of the faucet is arranged horizontally and includes a cold water inlet at one end and a hot water inlet in the middle. An interface, a mixing water valve core seat on the main body between the cold water inlet and the hot water inlet interface, and a mixing water interface at the other end of the main body, the axis of the cold water inlet coincides with the center line of the main body, the axis of the hot water inlet interface is perpendicular to the horizontal plane and the main body, the axis of the mixing water outlet interface is parallel to the horizontal plane and perpendicular to the center line of the main body, a cold water inlet hole, a hot water inlet hole and a mixing water outlet hole are arranged on the mixing water valve core seat, the valve core assembly includes a valve body, a combined valve core and a handle, and a water outlet joint is arranged at the water inlet end of the water outlet.

[0003] However, the split-type wall-mounted basin faucet also has some shortcomings: the valve core assembly is matched with the hot water inlet hole, cold water inlet hole and mixed water outlet hole on the water mixing valve core seat through the three holes at the bottom. Therefore, when the valve core assembly is connected to the water mixing valve core seat, the setting direction and swing direction of the handle are fixed and cannot be changed. For example, the handle is usually oriented downward and swung upward to switch. As a result, it is easy to be restricted by the surrounding installation environment during the actual decoration process, such as the low height from the basin, and the applicability is poor. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems existing in the prior art, and to propose a faucet main body and a pre-buried faucet assembly to solve the problem of poor applicability.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The faucet body includes a block-shaped valve seat, and the side of the valve seat is provided with three water holes. The characteristic is that the faucet body also includes a connecting seat that can be connected to the upper side of the valve seat, and the top of the connecting seat is provided with three water holes. The upper side of the valve seat is provided with a guide hole 1, an inner annular groove 1 and an outer annular groove 1 which are concentrically arranged and connected to the three water holes one-to-one, and the lower side of the connecting seat is correspondingly provided with a guide hole 2, an inner annular groove 2 and an outer annular groove 2 which are concentrically arranged and connected to the three water holes one-to-one. The connecting seat and the valve seat are detachable so that the connecting seat can be connected to the valve seat after changing the angle with the center line of the guide hole 1 as the center of the circle.

[0007] The connecting seat is connected to the valve seat, and then the valve core of the faucet is installed on the connecting seat. When the valve seat is connected to the connecting seat, two annular channels will be formed between the inner annular groove 1 and the inner annular groove 2 and between the outer annular groove 1 and the outer annular groove 2, respectively, and the guide hole 1 and the guide hole 2 are connected to form a direct current channel. When the faucet is used, two of the water holes are used for water inlet (i.e., one for hot water and one for cold water) and the remaining water hole is used for water outlet (i.e., mixed water), and two of the water holes are used for water outlet (i.e., one for hot water and one for cold water) and the remaining water hole is used for water inlet (i.e., mixed water). Now, take the two water holes connected with the inner annular groove 1 and the outer annular groove 1 for water inlet and the two water holes connected with the inner annular groove 2 and the outer annular groove 2 for water outlet as an example: when the handle is opened, hot water and cold water flow in from the two water holes for water inlet respectively, and then enter the two annular channels formed by the inner annular groove 1 and the inner annular groove 2 and the outer annular groove 1 and the outer annular groove 2 respectively (that is, hot water flows into one of the annular channels, and cold water flows into the other annular channel), and then flows into the valve core through the two water holes for water outlet to be mixed; after the hot water and the cold water are mixed in the valve core to form mixed water, they flow back from the valve core through the water holes for water outlet into the main body of the faucet, specifically, the mixed water first flows into the connecting seat through the water holes for water outlet, and then flows out through the direct current channel composed of the guide hole 2 and the guide hole 1 and the remaining water holes in sequence for use.

[0008] The main body of the faucet is added with a connecting seat, and an inner annular groove 1, an outer annular groove 1 and a guide hole 1 are arranged on the valve seat, and an inner annular groove 2, an outer annular groove 2 and a guide hole 2 are arranged on the connecting seat. Since the inner annular groove 1, the outer annular groove 1 and the guide hole are arranged concentrically, no matter how the angle of the connecting seat changes along the circumferential direction, the normal inlet of hot and cold water and outlet of mixed water can be achieved by relying on the cooperation of the inner annular groove 1 and the inner annular groove 2, the outer annular groove 1 and the outer annular groove 2, and the cooperation of the guide hole 1 and the guide hole 2. In this way, the installation angle of the valve core can be changed by changing the angle of the connecting seat along the circumferential direction, thereby changing the setting direction and swing direction of the handle, so as to ensure more flexibility during installation and improve applicability. Moreover, the method of providing the inner annular groove 1 and the outer annular groove 1 on the valve seat and the inner annular groove 2 and the outer annular groove 2 on the connecting seat is simpler and more convenient for processing technology.

[0009] In the above-mentioned faucet body, the guide hole 1 is laterally connected to the corresponding water hole, and two water diversion holes are also provided in the valve seat, one of which connects the inner annular groove 1 with the corresponding water hole, and the other connects the outer annular groove 1 with the corresponding water hole.

[0010] The water through hole is arranged on the side of the valve seat, while the inner annular groove 1 and the outer annular groove 1 are arranged on the upper side of the valve seat. Therefore, by processing two water inlet holes in the valve seat, the inner annular groove 1 and the outer annular groove 1 can be connected with the corresponding water through holes, thereby ensuring that the installation angle of the valve core can be changed by changing the circumferential angle of the connecting seat to improve applicability.

[0011] In the above-mentioned faucet body, the water inlet hole is opened along the center line direction of the guide hole 1, one end opening of the two water inlet holes is respectively connected to the corresponding water through hole laterally, and the other end openings of the two water inlet holes respectively penetrate the bottom walls of the inner annular groove 1 and the outer annular groove 1.

[0012] During processing, the corresponding water diversion holes are formed by directly using a drill bit to process downward from the bottom wall of the outer annular groove 1 and the bottom wall of the inner annular groove 1. This arrangement can improve applicability while making the processing technology simpler and the structural reliability higher.

[0013] In the above-mentioned faucet body, three independent water flow chambers are provided in the connecting seat, and the three water holes are connected one-to-one with the three water flow chambers, one of the water flow chambers is connected with the second guide hole, and the inner annular groove 2 and the outer annular groove 2 are connected one-to-one with the remaining two water flow chambers respectively.

[0014] By setting up the three water flow chambers, the inner annular groove 2, the outer annular groove 2 and the guide hole 2 and the three water holes can be connected one-to-one, thereby ensuring that the cold water and hot water flowing into the annular channel composed of the inner annular groove 1 and the inner annular groove 2 and the outer annular groove 1 and the outer annular groove 2 can smoothly flow through the water flow chamber to the corresponding water flow holes, ensuring that the installation angle of the valve core can be changed by changing the angle of the connecting seat along the circumferential direction, so as to improve applicability.

[0015] In the above-mentioned faucet body, the depths of the guide hole 2, the inner annular groove 2 and the outer annular groove 2 are all different, and the three water flow chambers are distributed along the circumferential direction. The entrance of one water flow chamber passes through the top wall of the inner annular groove 2, the entrance of another water flow chamber is connected to the upper port of the guide hole 2, and the entrance of the remaining water flow chamber passes through the inner edge groove wall of the outer annular groove 2.

[0016] Here, the orientation of the top wall and the upper port refers to the direction from the valve seat to the connecting seat. This opening method can make full use of the volume of the connecting seat, and the structure is more compact and the design is more reasonable while ensuring smooth water flow.

[0017] In the above-mentioned faucet body, sealing ring 1, sealing ring 2 and sealing ring 3 are embedded on the upper side of the valve seat or the lower side of the connecting seat. When the valve seat is connected to the connecting seat, sealing ring 1 and sealing ring 2 are located on both sides of the outer annular groove 1, sealing ring 2 and sealing ring 3 are located on both sides of the inner annular groove 1, and guide hole 1 is located on the inner side of sealing ring 3.

[0018] The provision of sealing ring 1, sealing ring 2 and sealing ring 3 can prevent cross-flow between the two annular channels formed by inner annular groove 1 and inner annular groove 2 and between outer annular groove 1 and outer annular groove 2, and the direct current channel formed by guide hole 1 and guide hole 2, thereby improving applicability and ensuring structural reliability.

[0019] In the above-mentioned faucet body, the valve seat has a plurality of connection holes 1 evenly distributed along the circumference, and the connection seat has a plurality of connection holes 2 evenly distributed along the circumference. The valve seat and the connection seat can be connected by screws passing through the connection holes 1 and the connection holes 2 in sequence. The circumference where each connection hole 1 is located is concentrically arranged with the guide hole, and the circumference where each connection hole 2 is located is concentrically arranged with the guide hole 2.

[0020] The connecting hole 1 is evenly distributed along the circumference of the valve seat, and the connecting hole 2 is evenly distributed along the circumference of the connecting seat, so that no matter how the angle of the connecting seat along the circumference changes, the inner annular groove 1 and the inner annular groove 2 will not be staggered, the outer annular groove 1 and the outer annular groove 2 will not be staggered, and the guide hole 1 and the guide hole 2 will not be staggered, thereby ensuring that the installation angle of the valve core can be changed by changing the angle of the connecting seat along the circumference to improve applicability.

[0021] The valve seat and the connecting seat are connected by screws passing through the connecting hole 1 and the connecting hole 2, and the circumference of each connecting hole 1 is concentrically arranged with the guide hole, and the circumference of each connecting hole 2 is concentrically arranged with the guide hole 2, which can ensure that no matter how the angle of the connecting seat along the circumferential direction is changed, the inner annular groove 1 and the inner annular groove 2 are opposite to each other, the outer annular groove 1 and the outer annular groove 2 are opposite to each other to form an annular channel, and the guide hole 1 and the guide hole 2 are opposite to each other to form a direct current channel, thereby changing the installation angle of the valve core by changing the angle of the connecting seat along the circumferential direction.

[0022] In the above-mentioned faucet body, the upper side of the valve seat is a square connecting plate 1, and each connecting hole 1 is located near the vertex position of the connecting plate 1. The lower side of the connecting seat is a square connecting plate 2, and each connecting hole 2 is located near the vertex position of the connecting plate 2.

[0023] Through the above arrangement, the connecting seat has four installation angles in the circumferential direction, and the handle can have four directions accordingly, namely, up, down, left and right directions.

[0024] In the above-mentioned faucet body, the upper side of the connecting seat is a circular protrusion, the circular protrusion is provided with an external thread, three water holes are provided at the top of the circular protrusion, and the top of the circular protrusion is also provided with two plug holes.

[0025] The embedded faucet assembly comprises a faucet body, a water outlet and a valve core. The faucet body comprises a valve seat, a water outlet joint connected to the water outlet and a water pipe connected between the two valve seats and the water outlet joints. The side of the valve seat is provided with three water through holes, and one end of the water through pipe is connected with one of the water through holes. The characteristic is that the faucet body also comprises a connecting seat which can be connected to the upper side of the valve seat, the top of the connecting seat is provided with three water through holes and two plug holes which can cooperate with the two pins at the bottom of the valve core, the upper side of the valve seat is provided with a guide hole 1, an inner annular groove 1 and an outer annular groove 1 which are concentrically arranged and connected with the three water through holes one to one, the lower side of the connecting seat is correspondingly provided with a guide hole 2, an inner annular groove 2 and an outer annular groove 2 which are concentrically arranged and connected with the three water through holes one to one, the connecting seat and the valve seat are detachable so that the connecting seat can be connected to the valve seat after changing the angle with the center line of the guide hole 1 as the center of the circle.

[0026] Compared with the prior art, the faucet body and the embedded faucet assembly of the present invention add a connecting seat on the basis of the valve seat, and by arranging an inner annular groove 1, an outer annular groove 1 and a guide hole 1 on the valve seat, and arranging an inner annular groove 2, an outer annular groove 2 and a guide hole 2 on the connecting seat, no matter how the angle of the connecting seat along the circumferential direction changes, the normal inlet and outlet mixing of cold and hot water can be achieved by relying on the cooperation of the inner annular groove 1 and the inner annular groove 2, the outer annular groove 1 and the outer annular groove 2, and the guide hole 1 and the guide hole 2, so that the installation angle of the valve core can be changed by changing the circumferential angle of the connecting seat, and then the setting direction and swing direction of the handle can be changed, so as to ensure greater flexibility during installation and improve applicability.

[0039] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0040] Embodiment 1

[0041] like Figure 1-Figure 3 As shown, the embedded faucet assembly includes an embedded box 1, a faucet body 16, a water outlet 3, a valve core 4 and a handle. The embedded box 1 has openings on both sides, and one of the openings is connected to a mounting plate 14, and the other opening is connected to a cover plate 2. The faucet body 16 is fixed in the embedded box 1, the valve core 4 and the water outlet 3 are both connected to the faucet body 16, and the handle is connected to the valve core 4, and the handle and the water outlet 3 are both located outside the cover plate 2. Among them, the faucet body 16 includes a valve seat 6, a water outlet joint 7, and a water pipe 8 connected therebetween. The water outlet joint 7 is connected to a connector 9, which extends out of the cover plate 2 and one end of the water outlet 3 is connected to the outside of the connector 9.

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the valve seat 6 is block-shaped, and three water holes 6a are provided on the side of the valve seat 6. One of the three water holes 6a is used for water discharge, and the remaining two are used for water intake, that is, one corresponds to cold water intake and the other corresponds to hot water intake. In this embodiment, the two water holes 6a for water intake are arranged on the same center line, and the side of the valve seat 6 has a water outlet interface 6h, which is opened in the same direction as the water hole 6a for water discharge and the two are connected. The water outlet interface 6h is used to connect the water pipe 8, that is, one end of the water pipe 8 is inserted into the water outlet interface 6h and is connected to the water hole 6a for water discharge, and the center line of the water hole 6a for water discharge is perpendicular to the center line of the water hole 6a for water intake. The side of the valve seat 6 also has two water inlet interfaces 6b, one of which is opened in the same direction as one of the water holes 6a for water inlet and the two are connected, and the other water inlet interface 6b is opened in the same direction as the other water hole 6a for water inlet and the two are connected. The two water inlet interfaces 6b extend out of the embedded box 1 respectively for connection with the hot water pipe and the cold water pipe.

[0043] Furthermore, if Figure 2-Figure 6 As shown, the faucet body 16 also includes a connection seat 10 that can be connected to the upper side of the valve seat 6. The top of the connection seat 10 (the top in the embodiment refers to the direction facing the opening of the embedded box 1) is provided with three water holes 10a and two plug holes 10b. Two of the water holes 10a are used for water discharge, that is, one corresponds to cold water discharge and the other corresponds to hot water discharge, and the remaining water hole 10a is used for water intake. The two plug holes 10b are used for inserting two pins 4a at the bottom of the valve core 4 to ensure that the two water holes 10a for water discharge can smoothly supply hot water and cold water into the valve core 4 for mixing, and ensure that the mixed water can smoothly flow back from the valve core 4 through the water hole 10a for water intake to the faucet body 16. The upper side of the connection seat 10 is a circular protrusion, and the outer surface of the circular protrusion is provided with an external thread. The outer surface of the valve core 4 is provided with a valve sleeve 15, and one end of the valve sleeve 15 is threadedly connected to the outside of the circular protrusion to limit the valve core 4.

[0044] like Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the upper side of the valve seat 6 is provided with a concentrically arranged guide hole 6c, an outer annular groove 6d and an inner annular groove 6e, the guide hole 6c is connected to one of the water holes 6a (used for water outlet in the present embodiment), the inner annular groove 6e is connected to one of the water holes 6a (used for water inlet in the present embodiment), and the outer annular groove 6d is connected to the remaining water hole 6a (used for water inlet in the present embodiment). The lower side of the connection seat 10 is correspondingly provided with a concentrically arranged flow guide hole 2 10c, an outer annular groove 2 10d and an inner annular groove 2 10e. The flow guide hole 2 10c is connected to one of the water holes 10a (used for water inlet in this embodiment), the inner annular groove 2 10e is connected to one of the water holes 10a (used for water outlet in this embodiment), and the outer annular groove 2 10d is connected to the remaining water hole 10a (used for water outlet in this embodiment). The connection seat 10 and the valve seat 6 are detachable so that the connection seat 10 can be connected to the valve seat 6 after changing the angle with the center line of the flow guide hole 1 6c as the center of the circle. The upper side of the valve seat 6 is embedded with a sealing ring 1 11, a sealing ring 2 12 and a sealing ring 3 13. The sealing ring 11 and the sealing ring 2 12 are located on both sides of the outer annular groove 1 6d, the sealing ring 2 12 and the sealing ring 3 13 are located on both sides of the inner annular groove 1 6e, and the flow guide hole 1 6c is located on the inner side of the sealing ring 3 13.

[0045] Specifically, if Figure 8-Figure 11 As shown, the flow guide hole 1 6c is laterally connected to the corresponding water through hole 6a, and two water guide holes 6f are also provided in the valve seat 6, one of which connects the inner annular groove 1 6e to the corresponding water through hole 6a, and the other water through hole 6f connects the outer annular groove 1 6d to the corresponding water through hole 6a. Both water guide holes 6f are opened along the center line direction of the flow guide hole 1 6c, one end of the two water guide holes 6f is laterally connected to the corresponding water through hole 6a, and the other end of the two water guide holes 6f penetrates the bottom wall of the outer annular groove 1 6d and the inner annular groove 1 6e, that is, one of the water guide holes 6f penetrates the bottom wall of the outer annular groove 1 6d, and the other water guide hole 6f penetrates the bottom wall of the inner annular groove 1 6e. Three independent water flow chambers 10f are arranged in the connection seat 10, and the openings at one end of the three water holes 10a are connected to the three water flow chambers 10f one-to-one, one of the water flow chambers 10f is connected to the guide hole 10c, and the inner annular groove 10e and the outer annular groove 10d are connected to the remaining two water flow chambers one-to-one. In this embodiment, the opening depths of the outer annular groove 10d, the inner annular groove 10e and the guide hole 1 6c are all different, and the three water flow chambers 10f are distributed along the circumferential direction. The three water flow chambers 10f are distributed along the circumferential direction, and the entrance of one of the water flow chambers 10f passes through the top wall of the inner annular groove 10e, the entrance of another water flow chamber 10f is connected to the upper port of the guide hole 10c, and the entrance of the remaining water flow chamber 10f passes through the inner edge groove wall of the outer annular groove 10d. This opening method can make full use of the volume of the connection seat 10, and the structure is more compact and the design is more reasonable while ensuring smooth water flow.

[0046] like Figure 2-Figure 5 As shown, the valve seat 6 has a plurality of connection holes 1 6g evenly distributed along the circumference, and the connection seat 10 has a plurality of connection holes 2 10g evenly distributed along the circumference. The valve seat 6 and the connection seat 10 can be connected by screws 17 that pass through the connection holes 1 6g and the connection holes 2 10g in sequence. The circumference where each connection hole 1 6g is located is concentric with the guide hole 1 6c, and the circumference where each connection hole 2 10g is located is concentric with the guide hole 2 10c. Specifically, the upper side of the valve seat 6 is a square connection plate 1, and each connection hole 1 6g is located at each vertex position close to the connection plate 1. The lower side of the connection seat 10 is a square connection plate 2, and each connection hole 2 10g is located at each fixed point position close to the connection plate 2.

[0047] When the valve seat 6 is connected to the connecting seat 10, two annular channels are formed between the outer annular groove 1 6d and the outer annular groove 2 10d and between the inner annular groove 1 6e and the inner annular groove 2 10e, respectively, and the guide hole 1 6c is directly connected to the guide hole 2 10c. The water discharge process of the embedded faucet assembly is as follows:

[0048] When the handle is opened, hot water and cold water flow in from the two water holes 6a for water inlet respectively, and then flow into the two annular channels formed by the inner annular groove 1 6e and the inner annular groove 2 10e and the outer annular groove 1 6d and the outer annular groove 2 10d respectively through the two water diversion holes 6f (that is, the hot water flows into one of the annular channels, and the cold water flows into the other annular channel), and then flow into the corresponding two water flow chambers 10f and flow into the valve core 4 through the two water holes 10a for water outlet to be mixed; the hot water and the cold water are mixed in the valve core 4 to form mixed water, and then flow back from the valve core 4 through the water holes 10a for water outlet to the faucet body 16, specifically, the mixed water first flows into the corresponding water flow chamber 10f in the connecting seat 10 through the water holes 10a for water outlet, and then flows into the water pipe 8 through the guide hole 2 10c and the guide hole 1 6c in turn, and finally flows out from the water outlet 3 for use.

[0049] In the embedded faucet assembly, a connecting seat 10 is added, and an outer annular groove 1 6d, an inner annular groove 1 6e and a flow guide hole 1 6c are arranged on the valve seat 6, and an outer annular groove 2 10d, an inner annular groove 2 10e and a flow guide hole 2 10c are arranged on the connecting seat 10. Since the outer annular groove 1 6d, the inner annular groove 1 6e and the flow guide hole 1 6c are arranged concentrically, no matter how the angle of the connecting seat 10 changes along the circumferential direction, the normal cold and hot water inlet and mixed water outlet can be achieved by the cooperation of the inner annular groove 1 6e and the inner annular groove 2 10e, the outer annular groove 1 6d and the outer annular groove 2 10d, and the flow guide hole 1 6c and the flow guide hole 2 10c. In this way, the installation angle of the valve core 4 can be changed by changing the circumferential angle of the connecting seat 10, thereby changing the setting direction and swing direction of the handle, so as to ensure more flexibility during installation and improve applicability.
