DETAILED DESCRIPTION

[0041] The utility model will be described in further detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, and not limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0042] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0043] In the utility model, unless otherwise explicitly specified and limited, the first feature "on" or "below" the second feature can include that the first and second features are in direct contact, or the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0044] In the description of the embodiment, the terms "up", "down", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0045] In the mechanical field, there are frequent scenarios where a first workpiece and a second workpiece need to be inserted and sealed. The first workpiece has an interface and a first channel that are angled and connected. The second workpiece has a second channel with several partitions arranged axially within it, dividing the second channel into several sub-channels. The second workpiece is inserted into the interface and extends into the first channel, dividing the first channel into a first cavity and a second cavity. One sub-channel communicates with either the first or second cavity. Understandably, a seal is needed to seal the first and second workpieces, ensuring that a sub-channel communicates with only one of the first or second cavities. However, because several sub-channels are angled to the second channel, and multiple sub-channels must also be sealed and not interconnected, traditional O-ring seals cannot achieve a seal with a single O-ring. Furthermore, attempting to use multiple O-rings for sealing presents assembly difficulties.

[0046] To address the aforementioned problems, this embodiment provides a three-dimensional sealing component 1, such as... Figure 1 As shown, this three-dimensional sealing assembly 1 includes a first sealing element 11, a plurality of second sealing elements 12, and a plurality of third sealing elements 13. The first sealing element 11 is sleeved on the outer periphery of the second workpiece to seal the first workpiece and the second workpiece along the axial direction of the second workpiece. One end of the plurality of second sealing elements 12 is connected to the first sealing element 11, and the second sealing elements 12 extend along the axial direction of the second workpiece to seal the first workpiece and the second workpiece along the axial direction of the first workpiece. Both ends of the plurality of third sealing elements 13 are respectively connected to the corresponding second sealing elements 12, and the third sealing elements 13 are sandwiched between the bottom wall of the second workpiece and the first workpiece to seal the first workpiece and the second workpiece along the axial direction of the first channel.

[0047] The first sealing element 11 forms an axial seal along the outer wall of the first workpiece, effectively blocking the medium permeation path along the insertion direction, preventing leakage between the second workpiece and the interface inner wall when the medium flows axially along the second channel. The second sealing element 12 forms a radial seal along the outer wall of the second workpiece, effectively blocking the medium permeation path along the first channel, preventing leakage between the second workpiece and the inner wall of the first channel when the medium flows axially along the first channel. The third sealing element 13 is sandwiched between the bottom wall of the second workpiece and the first workpiece, effectively blocking the medium permeation path along the first channel, preventing leakage between the bottom wall of the second workpiece and the inner wall of the first channel when the medium flows axially along the second channel, thus forming an end face seal in the first channel axial direction. This three-dimensional sealing assembly 1 ensures good sealing after the first and second workpieces are inserted, ensuring that the medium flows along the preset path without leakage. This integrated three-dimensional sealing assembly 1 can replace the traditional multi-ring stacking scheme, and sealing in all directions can be completed with a single press-in during installation, making installation simple and quick.

[0048] In an optional embodiment, the first seal 11, the second seal 12 and the third seal 13 are integrally formed. The integrally formed design makes the three-dimensional sealing assembly 1 seamlessly connected, forms a continuous sealing surface, and can completely block the medium leakage path; the integrally formed design does not need to be connected complicatedly, reduces the production time consumption; the integrally formed design has stronger durability and longer service life due to the complete structure and firm connection.

[0049] In another optional embodiment, the first seal 11, the second seal 12 and the third seal 13 are separately formed and then fixed to form the three-dimensional sealing assembly 1.

[0050] As shown in Figures 2-7 , the embodiment also provides a water inlet valve, which comprises a first valve body 2, a second valve body 3 and the three-dimensional sealing assembly 1 described above. The first valve body 2 has an inlet and outlet water interface 21 and a communication water cavity 22 which are arranged at an angle and are communicated; the second valve body 3 comprises an inlet and outlet water branch pipe 31 which is inserted into the inlet and outlet water interface 21 and extends into the communication water cavity 22 to divide the communication water cavity 22 into a water inlet cavity 221 and a water outlet cavity 222, and the inlet and outlet water branch pipe 31 is provided with a partition 311 in the axial direction thereof to divide the inner hole channel of the inlet and outlet water branch pipe 31 into a water inlet channel 312 and a water outlet channel 313, the water inlet cavity 221 and the water inlet channel 312 are communicated, the water outlet cavity 222 and the water outlet channel 313 are communicated, and the three-dimensional sealing assembly 1 is used for sealing insertion of the inlet and outlet water branch pipe 31 and the first valve body 2.

[0051] When the medium flows in the first valve body 2 and the second valve body 3 of the water inlet valve, the flow path thereof is shown by the arrow direction in Figure 3 , specifically from the water inlet cavity 221 to the water inlet channel 312, from the water inlet channel 312 to the water outlet channel 313, and from the water outlet channel 313 to the water outlet cavity 222. It should be noted that the top ends of the water inlet channel 312 and the water outlet channel 313 are communicated through a communication port 315 at this time, so that the medium can flow from the water inlet channel 312 to the water outlet channel 313. The medium in the embodiment can be water.

[0052] It can be understood that the first valve body 2 and the second valve body 3 at this time are the aforementioned first workpiece and second workpiece. When the three-dimensional sealing assembly 1 is used to plug seal the water inlet and outlet branch pipe 31 and the first valve body 2, the first sealing element 11 is sleeved on the outer periphery of the water inlet and outlet branch pipe 31, and at this time the first sealing element 11 is clamped between the water inlet and outlet branch pipe 31 and the inner wall of the water inlet and outlet interface 21 of the first valve body 2. When the medium flows along the water inlet channel 312 or the water outlet channel 313, the medium cannot penetrate and leak between the water inlet and outlet branch pipe 31 and the inner wall of the water inlet and outlet interface 21 of the first valve body 2. The second sealing element 12 is connected to the first sealing element 11 and extends along the axial direction of the water inlet and outlet branch pipe 31, and at this time at least part of the second sealing element 12 is clamped between the outer peripheral wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2. When the medium flows along the water inlet cavity 221 or the water outlet cavity 222, the medium cannot penetrate and leak between the outer peripheral wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2. The two ends of the third sealing element 13 are respectively connected to the corresponding second sealing element 12 and clamped between the bottom wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2. When the medium flows along the water inlet cavity 221 or the water outlet cavity 222, the medium cannot penetrate and leak between the bottom wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2. Through the three-dimensional sealing assembly 1, the first valve body 2 and the second valve body 3 can be effectively plug sealed, so that the medium can flow along the preset path when flowing in the first valve body 2 and the second valve body 3, and no external leakage occurs.

[0053] Compared with the prior art, the water inlet valve in the embodiment uses the three-dimensional sealing assembly 1 to plug seal between the first valve body 2 and the second valve body 3, solves the problem that the traditional sealing scheme is difficult to cope with the complex flow channel structure in the water inlet valve, ensures that the medium can flow along the preset path without any external leakage, and can be assembled at one time with a single piece, and the assembly time is short.

[0054] Specifically, as shown in Figure 6 , the side wall of the water inlet and outlet branch pipe 31 is provided with a first opening 316 and a second opening 317, the water inlet cavity 221 and the water inlet channel 312 are communicated through the first opening 316, and the water outlet cavity 222 and the water outlet channel 313 are communicated through the second opening 317. It can be understood that the first opening 316 and the second opening 317 are respectively located on the two sides of the water inlet and outlet branch pipe 31 delimited by the partition 311.

[0055] In the embodiment, as shown in Figure 1 , Figure 3 , Figure 4As shown, the number of the second seal 12 is two, and the two second seals 12 are located at the same horizontal plane as the partition 311 and on both sides of the partition 311; the number of the third seal 13 is one, and the third seal 13 is located at the same horizontal plane as the partition 311 and on the bottom side of the partition 311. The two seals are respectively located on both sides of the partition 311 to achieve isolation of the water inlet cavity 221 and the water outlet cavity 222, so that the water flowing from the water inlet cavity 221 can only enter the water inlet passage 312 and cannot leak into the water outlet cavity 222 or the water outlet passage 313 through the gap between the outer peripheral wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2; the third seal 13 is located on the bottom side of the partition 311 to achieve isolation of the water inlet cavity 221 and the water outlet cavity 222 and / or isolation of the water inlet passage 312 and the water outlet passage 313, so that the water flowing from the water inlet cavity 221 can only enter the water inlet passage 312 and cannot leak into the water outlet cavity 222 or the water outlet passage 313 through the gap between the bottom wall of the water inlet and outlet branch pipe 31 and the inner wall of the communication water cavity 22 of the first valve body 2, or so that the water in the water inlet passage 312 can only flow into the water outlet passage 313 through the top communication port 315 and cannot leak into the water outlet passage 313 through the gap between the bottom wall of the partition 311 and the inner wall of the communication water cavity 22 of the first valve body 2.

[0056] Specifically, the outer periphery of the water inlet and outlet branch pipe 31 is provided with a plurality of accommodating grooves, and the first seal 11, the second seal 12 and the third seal 13 are respectively accommodated in the corresponding accommodating grooves. The accommodating grooves provide accurate installation positions for the first seal 11, the second seal 12 and the third seal 13, ensuring that the positions of the three are consistent with the positions described above; the accommodating grooves can form fixed limiting positions for the first seal 11, the second seal 12 and the third seal 13, preventing displacement of the three; the accommodating grooves provide clear guidance for the installation of the first seal 11, the second seal 12 and the third seal 13, and during assembly, the first seal 11, the second seal 12 and the third seal 13 only need to be pressed into the corresponding accommodating grooves, thereby improving assembly efficiency.

[0057] Specifically, as shown, Figure 6 the accommodating grooves include a first accommodating groove 3141, a second accommodating groove 3142 and a third accommodating groove 3143, the first seal 11 is accommodated in the first accommodating groove 3141, the second seal 12 is accommodated in the second accommodating groove 3142, and the third seal 13 is accommodated in the third accommodating groove 3143. Among them, the first accommodating groove 3141 extends along the circumference of the water inlet and outlet branch pipe 31, the number of the second accommodating groove 3142 is two, the two second accommodating grooves 3142 extend along the axis of the water inlet and outlet branch pipe 31 and are located on both sides of the partition 311, and the third accommodating groove 3143 extends along the radial direction of the water inlet and outlet branch pipe 31 and is located on the bottom side of the partition 311.

[0058] Specifically, the cross-sectional area of the water inlet channel 312 is S1, and the cross-sectional area of the water outlet channel 313 is S2, wherein S1 / S2 < 1. That is, the water flow path of the water inlet channel 312 is smaller than that of the water outlet channel 313, thereby reducing the water resistance in the water outlet channel 313.

[0059] Specifically, as shown in Figure 2 、 Figure 3 、 Figure 5 The first valve body 2 has a water inlet interface 23 and a heat exchange inlet interface 24. The water inlet interface 23 is in communication with the water inlet cavity 221, the water outlet cavity 222 is in communication with the heat exchange inlet interface 24, and the heat exchange inlet interface 24 is connected to the heat exchange structure. The external water source enters the water inlet cavity 221 through the water inlet interface 23, then flows to the water inlet channel 312 through the water inlet cavity 221, flows to the water outlet channel 313 through the top communication port 315, and then flows to the water outlet cavity 222, and finally flows to the water supply channel of the heat exchange structure through the heat exchange inlet interface 24. The hot water in the heat exchange channel of the heat exchange structure exchanges heat to form warm water, and then flows to the water outlet valve, and finally flows to the bathroom pipeline from the outlet of the bathroom pipeline of the water outlet valve to provide domestic water for the user.

[0060] Specifically, a flow detection assembly is arranged between the water outlet cavity 222 and the heat exchange inlet interface 24. The flow detection assembly can monitor the water flow from the water outlet cavity 222 to the heat exchange inlet interface 24 in real time, and the detection data can monitor the flow anomaly in real time.

[0061] In this embodiment, as shown in Figure 5 The flow detection assembly includes an impeller and a flow sensor, and the first valve body 2 is provided with an impeller cavity 25 in communication with the water outlet cavity 222 and the heat exchange inlet interface 24. The impeller is arranged in the impeller cavity 25, and the flow sensor is in communication connection with the impeller. After the water flows out of the water outlet channel 313, it enters the impeller cavity 25 through the water outlet cavity 222. The water flows through the blades of the impeller to rotate the impeller, so that the flow sensor outputs a water flow signal to detect the water flow entering the heat exchange inlet interface 24, thereby facilitating accurate monitoring of the flow. Finally, the water enters the heat exchange structure through the outlet of the heat exchange inlet interface 24.

[0062] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For ordinary skilled persons in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application.
