[0023] To enable those skilled in the art to better understand the technical solution of this application, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-4 As shown, in this embodiment, the flow channel assembly 100 is provided with a flow channel E. The flow channel assembly 100 includes a first component 101 and a second component 102. The first component 101 and the second component 102 have grooves with openings facing each other, and the wall forming the flow channel E is located in the groove. The first component 101 and the second component 102 are stacked.

[0025] The first component 101 includes a first wall portion 1011 and a second wall portion 1012, wherein the second wall portion 1012 is located away from the flow channel E relative to the first wall portion 1011.

[0026] The second component 102 includes a third wall portion 1021 and a fourth wall portion 1022, the fourth wall portion 1022 being located away from the flow channel E relative to the third wall portion 1021.

[0027] There is a first gap F between the second wall portion 1012 and the first wall portion 1011, and between the fourth wall portion 1022 and the third wall portion 1021.

[0028] The stacking direction of the first component 101 and the second component 102 is defined as the first direction. The ends of the first component 101 and the second component 102 that are close to each other are defined as the first end, and the ends that are far apart are defined as the second end. The first end of the first wall portion 1011 is welded to the first end of the third wall portion 1021 to form a first welded portion A. The first end of the second wall portion 1012 is welded to the first end of the fourth wall portion 1022 to form a second welded portion B.

[0029] The first welded part A and the second welded part B are located within the first gap F, and the first welded part A and the second welded part B abut against each other in the first direction.

[0030] The aforementioned flow channel assembly 100 includes a first wall portion 1011, a second wall portion 1012, a third wall portion 1021, and a fourth wall portion 1022. A first gap F is formed between the first wall portion 1011 and the second wall portion 1012, and between the third wall portion 1021 and the fourth wall portion 1022. The first wall portion 1011 and the third wall portion 1021 are welded to form a first weld portion A, and the second wall portion 1012 and the fourth wall portion 1022 are welded to form a second weld portion B. The first weld portion A and the second weld portion B are located within the first gap F. The first weld portion A and the second weld portion B abut against each other in the stacking direction of the first component 101 and the second component 102. The interaction between the first weld portion A and the second weld portion B will prevent the first component 101 and the second component 102 from separating in the stacking direction, thereby improving the pressure resistance performance of the flow channel assembly.

[0031] Specifically, such as Figure 2 As shown, in this embodiment, the first wall portion 1011, the second wall portion 1012, the third wall portion 1021, and the fourth wall portion 1022 all extend along a first direction. The first wall portion 1011 circumferentially surrounds the flow channel E, the second wall portion 1012 circumferentially surrounds the first wall portion 1011, the third wall portion 1021 circumferentially surrounds the flow channel E, and the fourth wall portion 1022 circumferentially surrounds the third wall portion 1021. Along the first direction, the first wall portion 1011 protrudes towards the second component 102 relative to the second wall portion 1012; that is, the first end of the first wall portion 1011 extends beyond the first end of the second wall portion 1012 in the direction towards the second component 102. Along the first direction, the third wall portion 1021 is recessed away from the first component 101 relative to the fourth wall portion 1022; that is, the first end of the fourth wall portion 1022 extends beyond the first end of the third wall portion 1021 in the direction towards the first component 101. In this way, it is easier to control the weld penetration during welding to form a structure in which the first weld portion A and the second weld portion abut each other in the first direction. Alternatively, the first end of the second wall portion 1012 may extend beyond the first end of the first wall portion 1011 in a direction close to the second component 102, and the first end of the third wall portion 1021 may extend beyond the first end of the fourth wall portion 1022 in a direction close to the first component 101.

[0032] Specifically, such as Figure 2 As shown, in this embodiment, the wall forming the first gap F includes a first wall surface N1 and a second wall surface N2. The first wall surface N1 is located on the side of the first wall portion 1011 and the third wall portion 1021 away from the flow channel E, and the second wall surface N2 is located on the side of the second wall portion 1012 and the fourth wall portion 1022 close to the flow channel E. Figure 4 The first welding part A protrudes from the first wall surface N1 in the direction of the first gap F, and the second welding part B protrudes from the second wall surface N2 in the direction of the first gap F. The positions of the first welding part A and the second welding part B are staggered in the first direction.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the second end of the first wall portion 1011 is provided with a first end wall portion 1014, and the second end of the third wall portion 1021 is provided with a third end wall portion 1024. The wall forming the flow channel E includes the first wall portion 1011, the third wall portion 1021, the first end wall portion 1014, and the third end wall portion 1024.

[0034] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the first component 101 is provided with a channel portion 1016, the inner cavity of the channel portion 1016 is connected to the flow channel E, and the wall of the channel portion 1016 forming the inner cavity protrudes from the first end wall portion 1014 in a direction away from the second component 102.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, in this embodiment, the first end of the first wall portion 1011 is welded to the first end of the third wall portion 1021 to form a third weld portion C, and the first end of the second wall portion 1012 is welded to the first end of the fourth wall portion 1022 to form a fourth weld portion D. The third weld portion C protrudes from the side wall of the first wall portion 1011 and the third wall portion 1021 near the flow channel E in the direction of the flow channel E, and the fourth weld portion D protrudes from the side wall of the second wall portion 1012 and the fourth wall portion 1022 away from the flow channel E in the direction away from the flow channel E.

[0036] Specifically, such as Figure 4 As shown, in this embodiment, the second end of the first wall portion 1011 extends beyond the second wall portion 1012 in a direction away from the second component 102, and the second end of the third wall portion 1021 extends beyond the fourth wall portion 1022 in a direction away from the first component 101, which can ensure the formation of a flow channel E with a large volume.

[0037] Specifically, such as Figure 4 As shown, in this embodiment, a second end wall 1015 is provided at the second end of the second wall portion 1012, and the second end wall 1015 connects the second wall portion 1012 and the first wall portion 1011 into one unit. A fourth end wall 1025 is provided at the second end of the fourth wall portion 1022, and the fourth end wall 1025 connects the third wall portion 1021 and the fourth wall portion 1022 into one unit.

[0038] like Figures 5-7 As shown, this embodiment is in Figures 1-4 The illustrated embodiment further includes an exhaust channel X. The exhaust channel X connects the first gap F to the external space and is located in the second wall portion 1012 and / or the fourth wall portion 1022. This allows for timely pressure relief through the exhaust channel X when air in the first gap F expands, preventing the flow channel assembly 100 from deforming or even cracking due to excessive pressure in the first gap F.

[0039] Specifically, Figures 5-7 In the illustrated embodiment, the exhaust groove X includes a first exhaust groove portion 1012a and a second exhaust groove portion 1022a. The first exhaust groove portion 1012a is located in the second wall portion 1012, and the second exhaust groove portion 1022a is located in the fourth wall portion 1022. Figure 6As shown, before the first component 101 and the second component 102 are welded, the first venting groove 1012a has a first slot K1 on the side near the fourth wall 1022. The second venting groove 1022a has a second slot K2 on the side near the second wall 1012, thus facilitating the integral molding of the first component 101 and the second component 102 by means of a mold. Alternatively, the first venting groove 1012a and the second venting groove 1022a can also be through-hole structures with complete peripheral walls. Alternatively, either the first venting groove 1012a or the second venting groove 1022a can be selected.

[0040] Specifically, the number of first exhaust grooves 1012a can be one or more, and the multiple first exhaust grooves 1012a are arranged alternately in the circumferential direction. The number of second exhaust grooves 1022a can also be one or more, and the multiple second exhaust grooves 1022a are arranged alternately in the circumferential direction. The first slot K1 of each first exhaust groove 1012a and the second slot K2 of each second exhaust groove 1022a are aligned with each other in the first direction.

[0041] like Figures 8-11 As shown, this embodiment is in Figures 1-4 Based on the embodiment shown, a fifth wall portion 1013 and a sixth wall portion 1023 are further provided. Alternatively, they can also be provided in... Figures 5-7 The embodiment shown is further provided with a fifth wall portion 1013 and a sixth wall portion 1023.

[0042] Specifically, such as Figure 9 As shown, in this embodiment, the fifth wall portion 1013 belongs to the first component 101, and is located on the side of the first wall portion 1011 near the flow channel E, circumferentially surrounding the flow channel E. The sixth wall portion 1023 belongs to the second component 102, and is located on the side of the third wall portion 1021 near the flow channel E, circumferentially surrounding the flow channel E. Figure 11 As shown, the first end of the fifth wall portion 1013 and the first end of the sixth wall portion 1023 are connected. The connection method is not limited; for example, it can be a surface contact connection, bonding, or a sealed connection with a sealing gasket between them. There is a second gap G between the fifth wall portion 1013 and the first wall portion 1011, and between the sixth wall portion 1023 and the third wall portion 1021. The aforementioned third welded portion C is located within the second gap G. In this way, the third welded portion C can be prevented from being directly exposed in the flow channel E, thus avoiding affecting the fluid flow resistance and cleanliness in the flow channel E.

[0043] Specifically, such as Figure 9As shown, in this embodiment, a first end wall portion 1014 is disposed at the second end of a fifth wall portion 1013, and a third end wall portion 1024 is disposed at the second end of a sixth wall portion 1023. The wall forming the flow channel E includes the fifth wall portion 1013, the sixth wall portion 1023, the first end wall portion 1014, and the third end wall portion 1024. A second end wall portion 1015 is disposed at the second end of the first wall portion 1011 and the second wall portion 1012, and the first wall portion 1011, the second wall portion 1012, and the fifth wall portion 1013 are connected as one unit through the second end wall portion 1015. A fourth end wall portion 1025 is disposed at the second end of the third wall portion 1021 and the fourth wall portion 1022, and the third wall portion 1021, the fourth wall portion 1022, and the sixth wall portion 1023 are connected as one unit through the fourth end wall portion 1025.

[0044] Specifically, such as Figure 9 As shown, in this embodiment, the second end of the fifth wall portion 1013 extends beyond the second ends of the first wall portion 1011 and the second wall portion 1012 in a direction away from the second component 102, and the second end of the sixth wall portion 1023 extends beyond the second ends of the third wall portion 1021 and the fourth wall portion 1022 in a direction away from the first component 101. In this way, a flow channel E with a large volume can be formed.

[0045] In some embodiments, the flow channel assembly 100 is a plastic part, in which case the first component 101 and the second component 102 can be injection molded. The first component 101 and the second component are welded together, and the welding method includes, but is not limited to, hot plate welding, infrared welding, and friction welding.

[0046] In some embodiments, the first component 101 is a plug and the second component 102 is a pipe fitting.

[0047] The above examples illustrate the principles and implementation methods of this application. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
