[0053] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0054] See also Figure 1 and Figure 2 In the related art, the concealed faucet 1 generally includes a concealed valve body 11, which includes a mixing seat 111, a hot water inlet pipe and a cold water inlet pipe, and the hot water inlet pipe and the cold water inlet pipe are both connected to the mixing seat 111. The hot water in the hot water inlet pipe and the cold water in the cold water inlet pipe are transported to the mixing seat 111, and are mixed in the mixing seat 111 and then output.

[0055] However, in actual application, the cold water and hot water in the water mixing seat 111 are not mixed evenly, resulting in the output warm water having a temperature that cannot meet the demand.

[0056] After in-depth research, the researchers of this application found that the key factor leading to uneven mixing of hot water and cold water is that the mixing time of cold water and hot water is too short, so the cold water and hot water cannot be fully mixed.

[0057] Example 2: Please refer again Figures 2 to 9 Based on this, in order to alleviate the problem of uneven mixing of cold water and hot water, the applicant designed a concealed valve body 11, which includes a mixing seat 111, a connecting component 112, a water distribution seat 113, a first water inlet pipe 114, a second water inlet pipe 115, a first water outlet pipe 116 and a second water outlet pipe 117.

[0058] by Figures 6 to 9 As shown, the water mixing seat 111 includes a water mixing chamber 1111, and a first water inlet hole 1112 and a second water inlet hole 1113 both connected to the water mixing chamber 1111, and the first water inlet hole 1112 and the second water inlet hole 1113 are arranged along the axial direction of the water mixing chamber 1111 (such as Figure 3 and Figure 6 The second water inlet hole 1113 is arranged as indicated by the arrow X in the middle, and there is a height difference between the two, such as the second water inlet hole 1113 is far away from the opening of the mixing chamber 1111 relative to the first water inlet hole 1112.

[0059] Moreover, the water mixing seat 111 is fixedly connected with the first water inlet pipe 114 and the second water inlet pipe 115 and communicates with each other. For example, the water mixing seat 111 is integrally arranged with the first water inlet pipe 114 and the second water inlet pipe 115, and the first water inlet pipe 114 has a first water inlet flow channel 1141, and the second water inlet pipe 115 has a second water inlet flow channel 1151. The first water inlet flow channel 1141 communicates with the water mixing chamber 1111 through the first water inlet hole 1112, and the second water inlet flow channel 1151 communicates with the water mixing chamber 1111 through the second water inlet hole 1113. The first water inlet pipe 114 is one of the cold water inlet pipe and the hot water inlet pipe, and the second water inlet pipe 115 is the other of the cold water inlet pipe and the hot water inlet pipe.

[0060] For ease of explanation, the following embodiments are described by taking the first water inlet pipe 114 as a cold water inlet pipe, the first water inlet channel 1141 flowing with cold water, the second water inlet pipe 115 as a hot water inlet pipe, and the second water inlet channel 1151 flowing with hot water as an example.

[0061] As an example, the shape of the first water inlet flow channel 1141 is the same as the shape of the second water inlet flow channel 1151. For example, the first water inlet flow channel 1141 and the second water inlet flow channel 1151 can be formed by the same processing method and the same mold. It can be understood that the shape of the first water inlet flow channel 1141 is the same as the shape of the second water inlet flow channel 1151, which can be understood as the shape of the first water inlet flow channel 1141 and the shape of the second water inlet flow channel 1151 are substantially the same, and there is a processing error.

[0062] In actual operation, the first water inlet channel 1141 inputs cold water into the mixing water chamber 1111 through the first water inlet hole 1112, and the second water inlet channel 1151 inputs hot water into the mixing water chamber 1111 through the second water inlet hole 1113. The cold water and the hot water are mixed in the mixing water chamber 1111 and then output from the mixing water chamber 1111. Since the first water inlet hole 1112 and the second water inlet hole 1113 are arranged along the axial direction of the mixing water chamber 1111 and there is a height difference between the two, under such a design, the time that the cold water and the hot water stay in the mixing water chamber 1111 is increased, so that the cold water and the hot water can be fully mixed, the mixing is more uniform, and the temperature of the warm water formed after mixing meets the demand.

[0063] Please refer again Figures 2 to 6 , and also see Fig.10 and Fig.11The water diversion seat 113 includes a water diversion chamber 1131, and a first water outlet hole 1132 and a second water outlet hole 1133 both connected to the water diversion chamber 1131. The connecting component 112 connects the water mixing seat 111 and the water diversion seat 113. The connecting component 112 includes a connecting channel 1121, and the connecting channel 1121 connects the water diversion chamber 1131 and the water mixing chamber 1111. The connecting component 112 is used to connect the water mixing seat 111 and the water diversion seat 113 to achieve the fixation between the water mixing seat 111 and the water diversion seat 113, such as the water mixing seat 111, the connecting component 112 and the water diversion seat 113 are integrally arranged. Moreover, the connecting component 112 is also used to connect the water mixing seat 111 and the water diversion seat 113, and can input the mixed warm water in the water mixing chamber 1111 into the water diversion chamber 1131.

[0064] Among them, there are height differences among the first water inlet hole 1112 , the second water inlet hole 1113 , and the end of the connecting channel 1121 communicating with the mixing water chamber 1111 , and the end of the connecting channel 1121 communicating with the mixing water chamber 1111 is far away from the opening of the mixing water chamber 1111 .

[0065] During the actual mixing process, the cold water input into the mixing water chamber 1111 through the first water inlet hole 1112 is fully mixed to form mixed water when it flows through the flow path of the hot water input into the mixing water chamber 1111 through the second water inlet hole 1113, and then flows to the connecting channel 1121. In this way, not only the time that the cold water and the hot water stay in the mixing water chamber 1111 is increased, but also the flow paths of the cold water and the hot water input into the mixing water chamber 1111 through the first water inlet hole 1112 and the second water inlet hole 1113 partially overlap, which is conducive to the full mixing of the cold water and the hot water, and the mixing is more uniform, which can meet the water temperature requirements. In addition, in this embodiment, the design that the end of the connecting channel 1121 that is connected to the mixing water chamber 1111 is far away from the opening of the mixing water chamber 1111 also helps to reduce the risk of mixed water overflowing from the valve port, and is more reliable to use.

[0066] In the present application, in order to facilitate the forming of the water diversion chamber 1131 , a water diversion groove may be firstly provided on the water diversion seat 113 , and then the notch of the water diversion groove may be blocked by the plug 118 to form the water diversion chamber 1131 .

[0067] In some optional embodiments of this application, please refer again to Figures 2 to 6 Furthermore, the first water inlet hole 1112, the second water inlet hole 1113, and the end of the connecting channel 1121 communicating with the water mixing chamber 1111 are arranged along the circumference of the water mixing chamber 1111 (such as Figure 3The first water inlet channel 1141, the second water inlet channel 1151 and the connecting channel 1121 are also staggered along the circumference of the mixing water chamber 1111, so that the first water inlet pipe 114, the second water inlet pipe 115 and the connecting component 112 can also be staggered along the circumference of the mixing water chamber 1111, and finally the first water inlet pipe 114, the second water inlet pipe 115 and the connecting component 112 are staggered and installed without interfering with each other.

[0068] In some optional embodiments of this application, please refer again to Figures 2 to 6 , wherein the cavity wall of the water mixing chamber 1111 is raised and structured to form a first separation ring 1116 and a second separation ring 1117, the first water inlet hole 1112 and the second water inlet hole 1113 are separated by the first separation ring 1116, and the second water inlet hole 1113 and the end of the connecting channel 1121 away from the water separation seat 113 are separated by the second separation ring 1117. For example, the first water inlet hole 1112 is located on the side of the first separation ring 1116 facing the opening of the water mixing chamber 1111, the second water inlet hole 1113 is located between the first separation ring 1116 and the second separation ring 1117, and the end of the connecting channel 1121 away from the water separation seat 113 is located on the side of the second separation ring 1117 facing away from the opening of the water mixing chamber 1111. Alternatively, it can also be as follows Figure 6 As shown, the first water inlet 1112 is located on the side of the opening of the first separation ring 1116 facing the mixing chamber 1111, the second water inlet 1113 is located between the first separation ring 1116 and the second separation ring 1117, and the end of the connecting channel 1121 away from the water separation seat 113 is located on the second separation ring 1117.

[0069] Combination Fig.11 The water mixing chamber 1111 can accommodate a water mixing valve core 12, and the water mixing valve core 12 is used to control the water inlet ratio of the first water inlet hole 1112 and the second water inlet hole 1113 to achieve water temperature regulation.

[0070] The first spacer ring 1116 and the second spacer ring 1117 are used to support and install the water mixing valve core 12. During actual installation, the water mixing valve core 12 is synchronously inserted into the center holes of the first spacer ring 1116 and the second spacer ring 1117, and contacts the hole walls of the center holes of the first spacer ring 1116 and the second spacer ring 1117. Due to the existence of the first spacer ring 1116 and the second spacer ring 1117, an installation gap is formed between the water mixing valve core 12 and the cavity wall of the water mixing chamber 1111, so as to avoid the water mixing valve core 12 and the cavity wall of the water mixing chamber 1111 being too tightly attached to each other, so that the cold water of the first water inlet hole 1112 and the hot water of the second water inlet hole 1113 cannot flow smoothly into the water mixing chamber 1111, thereby ensuring the reliability of the input of cold water and hot water.

[0071] In the embodiment in which one end of the connecting channel 1121 away from the water diversion seat 113 is located on the second separation ring 1117, the water mixing valve core 12 is in close contact with the hole wall of the center hole of the second separation ring 1117, resulting in a slowdown in the flow of warm water to the connecting channel 1121. Therefore, the flow rate of cold water and hot water is also slowed down. In this way, the cold water and hot water stay in the mixing chamber 1111 for a longer time and are mixed more fully.

[0072] In some optional embodiments of the present application, the water mixing seat 111 further includes a first guide port 1114 communicating with the water mixing chamber 1111 and the first water inlet hole 1112, and the size of the first guide port 1114 gradually increases from a side close to the first water inlet pipe 114 toward a side away from the first water inlet pipe 114; and / or

[0073] The water mixing seat 111 further includes a second guide port 1115 communicating with the water mixing chamber 1111 and the second water inlet hole 1113 . The size of the second guide port 1115 gradually increases from a side close to the second water inlet pipe 115 to a side away from the second water inlet pipe 115 .

[0074] Preferably, the mixing seat 111 also includes a first guide port 1114 connecting the mixing chamber 1111 and the first water inlet hole 1112, and the size of the first guide port 1114 gradually increases from the side close to the first water inlet pipe 114 toward the side away from the first water inlet pipe 114; and the mixing seat 111 also includes a second guide port 1115 connecting the mixing chamber 1111 and the second water inlet hole 1113, and the size of the second guide port 1115 gradually increases from the side close to the second water inlet pipe 115 toward the side away from the second water inlet pipe 115.

[0075] It can be understood that the cold water from the first water inlet hole 1112 enters the mixing water chamber 1111 through the first guide port 1114 , and the hot water from the second water inlet hole 1113 enters the mixing water chamber 1111 through the second guide port 1115 .

[0076] The size of the first guide port 1114 gradually increases from the side close to the first water inlet pipe 114 to the side away from the first water inlet pipe 114, which can be understood as the cross-sectional area of ​​the first guide port 1114 gradually increases from the side close to the first water inlet pipe 114 to the side away from the first water inlet pipe 114, or the inner diameter gradually increases, etc. The size of the second guide port 1115 gradually increases from the side close to the second water inlet pipe 115 to the side away from the second water inlet pipe 115, which can be understood as the cross-sectional area of ​​the second guide port 1115 gradually increases from the side close to the second water inlet pipe 115 to the side away from the second water inlet pipe 115, or the inner diameter gradually increases, etc.

[0077] Specifically, the size of the first water inlet hole 1112 is much smaller than the size of the water mixing chamber 1111. When cold water is directly input into the water mixing chamber 1111 from the first water inlet hole 1112, a bursting feeling will be generated due to the sudden increase in space, and the impact force on the water mixing valve core 12 will be too large. In this embodiment, the size of the first guide port 1114 gradually increases from the side close to the first water inlet pipe 114 to the side away from the first water inlet pipe 114. In the process of the cold water in the first guide port 1114 flowing into the water mixing chamber 1111, the space for the cold water to flow gradually increases. In this way, the cold water continuously diffuses in the first guide port 1114 and then flows into the water mixing chamber 1111, which can reduce the impact force of the cold water on the water mixing valve core 12 and extend the service life of the water mixing valve core 12.

[0078] Similarly, the size of the second water inlet hole 1113 is much smaller than the size of the water mixing chamber 1111. When hot water is directly input into the water mixing chamber 1111 through the second water inlet hole 1113, the impact force on the water mixing valve core 12 is too large. In this embodiment, the size of the second guide port 1115 gradually increases from the side close to the second water inlet pipe 115 to the side away from the second water inlet pipe 115. Therefore, hot water continuously diffuses in the second guide port 1115 and then flows into the water mixing chamber 1111, which can reduce the impact force of hot water on the water mixing valve core 12 and further extend the service life of the water mixing valve core 12.

[0079] In some optional embodiments of the present application, the first water inlet pipe 114 includes a first installation groove 1142 and a third guide port 1143, the first installation groove 1142 is used to install the first one-way valve 13, the first water inlet channel 1141 is connected to the first installation groove 1142, the third guide port 1143 is connected to the first installation groove 1142, and the size of the third guide port 1143 gradually decreases from the side away from the mixing seat 111 to the side close to the mixing seat 111;

[0080] The second water inlet pipe 115 includes a second installation groove 1152 and a fourth guide port 1153. The second installation groove 1152 is used to install the second one-way valve 14. The second water inlet channel 1151 is connected to the second installation groove 1152. The fourth guide port 1153 is connected to the second installation groove 1152. The size of the fourth guide port 1153 gradually decreases from the side away from the mixing water seat 111 to the side close to the mixing water seat 111.

[0081] In actual operation, cold water flows into the mixing chamber 1111 through the first water inlet channel 1141, the first mounting groove 1142, the third flow guide 1143, the first water inlet hole 1112 and the first flow guide 1114 in sequence. Hot water flows into the mixing chamber 1111 through the second water inlet channel 1151, the second mounting groove 1152, the fourth flow guide 1153, the second water inlet hole 1113 and the second flow guide 1115 in sequence.

[0082] For example, the first mounting groove 1142 and the second mounting groove 1152 have the same shape and are equal in size, and the third guide port 1143 and the fourth guide port 1153 have the same shape and are equal in size. In this way, the first mounting groove 1142 and the second mounting groove 1152 can be processed and formed by the same processing method and the same mold, and the third guide port 1143 and the fourth guide port 1153 can be processed and formed by the same processing method and the same mold.

[0083] A first one-way valve 13 is installed in the first installation groove 1142, and a second one-way valve 14 is installed in the second installation groove 1152. Both the first one-way valve 13 and the second one-way valve 14 are check valves, which can prevent the backflow of water in the first water inlet channel 1141 and the second water inlet channel 1151. On the one hand, the reliability of the inlet of cold water and hot water is guaranteed. On the other hand, it is also helpful to reduce the noise caused by the backflow of water and improve the noise reduction effect.

[0084] According to fluid mechanics, when the flow rate remains unchanged, the smaller the cross-sectional area, the faster the flow rate. The size of the third guide port 1143 gradually decreases from the side away from the mixing water seat 111 to the side close to the mixing water seat 111. Therefore, when the same flow of cold water enters the third guide port 1143, the size of the third guide port 1143 gradually narrows, which speeds up the flow of cold water, thereby helping to reduce the time for cold water to flow into the mixing water chamber 1111. Similarly, the size of the fourth guide port 1153 gradually decreases from the side away from the mixing water seat 111 to the side close to the mixing water seat 111, and the flow rate of hot water flowing into the mixing water chamber 1111 is also increased. Therefore, the response sensitivity of the valve body is also higher.

[0085] Please refer again Fig.10 and Fig.11 In some optional embodiments of the present application, the concealed valve body 11 includes at least a groove 1122 opened on the connecting component 112 , and the opening of the groove 1122 is connected to the water diversion chamber 1131 and is not connected to the water mixing chamber 1111 .

[0086] For example, the groove 1122 may be a strip groove, a circular groove or other groove structures.

[0087] The opening of the groove 1122 is not connected to the water mixing chamber 1111, so that the mixed water in the water mixing chamber 1111 can only flow into the water diversion chamber 1131 through the connecting channel 1121. The opening of the groove 1122 is connected to the water diversion chamber 1131, so a small part of the mixed water transported to the water diversion chamber 1131 by the connecting channel 1121 flows into the groove 1122, so the water pressure in the water diversion chamber 1131 can be reduced, and the service life of the water diversion seat 113 can be extended.

[0088] In addition, in order to improve the mechanical strength of the connection between the water separation seat 113 and the water mixing seat 111, it is necessary to increase the width of the connecting component 112 in the axial direction of the water mixing chamber 1111. However, this design will increase the material of the connecting component 112, and the weight of the entire valve body will also increase accordingly. Therefore, in this case, a groove 1122 can be designed. The design of the groove 1122 can appropriately reduce the weight of the connecting component 112 while ensuring that the connecting component 112 has a high connection strength with the water mixing seat 111 and the water separation seat 113, which is conducive to achieving lightweight valve body.

[0089] Further, in some optional embodiments of the present application, the groove 1122 is opened in the water diversion seat 113 and the connecting part 112, and ends at the connection between the water mixing seat 111 and the connecting part 112; or, the groove 1122 is opened in the water diversion seat 113 and the connecting part 112, and ends at the part of the connecting part 112 close to the water mixing seat 111.

[0090] That is, the groove 1122 extends along the length direction of the connecting member 112 and occupies at least a majority of the length direction of the connecting member 112. It can be understood that the greater the length of the groove 1122, the better the weight reduction effect, thereby further achieving the purpose of lightweighting the valve body.

[0091] In some optional embodiments of the present application, the opening of the groove 1122 is located on the same end face as and adjacent to the end of the connecting channel 1121 away from the water mixing seat 111. Under this design, after the mixed water input from the connecting channel 1121 into the water diversion chamber 1131 enters the water diversion chamber 1131, it quickly passes through the opening of the groove 1122 and enters the groove 1122 for diversion, which reduces the bursting feeling caused by the sudden increase in space when the warm water enters the water diversion chamber 1131, weakens the water pressure on the wall of the water diversion chamber 1131, and is conducive to extending the service life of the valve body.

[0092] As an example, the axis of the groove 1122 and the axis of the connecting channel 1121 are inclined to each other to form an acute angle.

[0093] As an example, the axis of the groove 1122 is substantially perpendicular to the axis of the water mixing chamber 1111, and the connecting channel 1121 is arranged to be inclined downward from the water diversion seat 113 to the water mixing seat 111 relative to the axis of the groove 1122. In this case, after the water mixing seat 111 achieves the mixing of cold water and hot water, the mixed water is transported to the water diversion chamber 1131 of the water diversion seat 113 through the connecting channel 1121 of the connecting component 112. On the one hand, the mixed water needs to overcome a certain gravity, which can reduce the water pressure, and on the other hand, a part of the mixed water entering the water diversion seat 113 can flow into the groove 1122. Therefore, combined with being able to reduce the water pressure and ensuring the strength of the connection part 112 and the water diversion seat 113 and the water mixing seat 111, it can also effectively reduce weight, save materials, and reduce costs.

[0094] In some optional embodiments of the present application, the diameter of the groove 1122 is substantially equal to the diameter of the connecting channel 1121 ; and / or the height of the connecting component 112 along the axis of the water mixing chamber 1111 is slightly smaller than the height of the water diversion seat 113 along the axis of the water mixing chamber 1111 .

[0095] The diameter of the groove 1122 is substantially equal to the diameter of the connecting channel 1121 , so during the machining process, the same machining parts can be used to machine the groove 1122 and the connecting channel 1121 , without the need to use a variety of machining parts, thus facilitating machining.

[0096] The height of the connecting component 112 along the axial direction of the water mixing chamber 1111 is slightly smaller than the height of the water diversion seat 113 along the axial direction of the water mixing chamber 1111, which can be understood as the connecting component 112 slightly retracts relative to the water diversion seat 113 in the axial direction of the water mixing chamber 1111. For example, the connecting component 112 retracts relative to the water diversion seat 113 in the axial direction of the water mixing chamber 1111 by 1 mm, 1.5 mm, etc. In this way, while ensuring that the connecting component 112 has a better connection strength with the water diversion seat 113 and the water mixing seat 111, the connecting component 112 will not be too heavy. In other words, under this design, both the connection strength can be improved and the valve body can be lightweight.
