Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] At present, refrigerators are usually provided with an ice-making device for making ice. The refrigerator includes a box body and a refrigeration door body rotatably connected to the box body. An equipment compartment for accommodating a refrigeration system and a driving fan is provided in the box body, and a first air duct connected to the equipment compartment is also formed. The refrigeration door body is provided with an ice-making compartment for accommodating the ice-making device, and a second air duct connected to the ice-making compartment is also formed. A sealing ring is provided between the first air duct and the second air duct. When the refrigeration door body is closed, the first air duct and the second air duct are sealed and connected through the sealing ring. The wind generated by the driving fan circulates in the ice-making compartment and the equipment compartment via the connected first air duct and the second air duct, so as to release the cold energy generated by the refrigeration system into the ice-making compartment for use by the ice-making device. However, the sealing ring in the related art has poor sealing performance and is prone to cold energy leakage. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator that can solve the technical problem in the related art that the sealing performance of the sealing ring is poor and easily causes cold leakage.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0005] A box body is provided with a refrigeration compartment; a first air duct is arranged inside the box body, the first air duct is connected with the refrigeration compartment, and the first air duct forms a first air outlet on the surface of the refrigeration compartment;

[0006] A refrigeration door body is rotatably connected to the box body and is used to open or close the refrigeration compartment. The refrigeration door body is configured with an ice-making compartment. A second air duct is arranged inside the refrigeration door body, and the second air duct is connected to the ice-making compartment. The second air duct forms a second air outlet on the surface of the refrigeration door body. A connecting groove is arranged on one side of the refrigeration door body having the second air outlet, and the connecting groove is spaced apart from the second air outlet and surrounds the second air outlet.

[0007] A sealing ring, which is configured to seal and connect the first air outlet and the second air outlet when the refrigeration door is closed; the sealing ring includes:

[0008] An annular clamping portion, which is clamped in the connecting groove;

[0009] The sealing body comprises a fixed end and a movable end opposite to each other, wherein the fixed end is connected to the clamping portion; the movable end is closer to the second air outlet than the fixed end, and the movable end is connected to an extension portion, which extends into the second air duct.

[0010] In the refrigerator of the embodiment of the present application, the extension portion is capable of blocking the air in the second air inlet channel and extending the leakage path of the air in the second air inlet channel, reducing the amount of air entering between the annular clamping portion and the side wall of the connecting groove, thereby reducing the amount of air flowing out from between the fixed end and the side wall of the refrigeration door body, improving the sealing performance of the sealing ring, and further reducing the amount of leaked cold.

[0011] In some embodiments of the present application, the annular clamping portion has a first side and a second side relative to each other, and the first side is farther away from the second air outlet than the second side; the sealing ring also includes a first connecting portion and a second connecting portion; the first connecting portion connects the first side and the fixed end, and abuts against the refrigeration door body; the second connecting portion is connected to the second side, and abuts against the refrigeration door body.

[0012] In this way, by setting the first connection part and the second connection part, the length of the sealing ring and the refrigeration door body is the sum of the length of the first connection part and the refrigeration door body and the length of the second connection part and the refrigeration door body. Compared with the related art, the effective sealing length between the sealing ring and the refrigeration door body in the embodiment of the present application is longer and the sealing performance is better.

[0013] In some embodiments of the present application, the sealing body, the first connecting portion, the annular clamping portion and the second connecting portion are arranged to form a first deformation space having an opening, and the opening is adjacent to the second air outlet.

[0014] With such arrangement, when the refrigeration door is closed, the refrigeration door squeezes the sealing body, which can increase the deformation of the sealing body, thereby increasing the contact area between the sealing body and the side wall of the refrigeration compartment, and improving the reliability of the sealing connection between the first air inlet and the second air inlet.

[0015] In some embodiments of the present application, a second deformation space is provided in the annular clamping portion, and the second deformation space is communicated with the first deformation space.

[0016] In this way, by setting a second deformation space in the annular clamping part, when the annular clamping part is inserted into the connecting groove, the groove wall of the connecting groove squeezes the annular clamping part, which can increase the deformation of the annular clamping part, thereby increasing the contact area between the annular clamping part and the groove wall of the connecting groove, improving the connection strength between the annular clamping part and the groove wall of the connecting groove, and preventing the annular clamping part from detaching from the connecting groove.

[0017] In some embodiments of the present application, the annular clamping portion has a first clamping protrusion on one side of the groove wall facing the connecting groove; the side wall of the connecting groove is provided with a second clamping protrusion, and the side of the second clamping protrusion facing away from the notch of the connecting groove abuts against the side of the first clamping protrusion facing the sealing body.

[0018] In this way, by providing the first clamping protrusion and the second clamping protrusion that abut against each other, the connection strength between the annular clamping part and the groove wall of the connecting groove can be improved to prevent the annular clamping part from detaching from the connecting groove.

[0019] In some embodiments of the present application, an extension direction of the first clamping protrusion is along the annular clamping portion and points toward the sealing body and away from the annular clamping portion.

[0020] Such an arrangement can make the abutment force applied by the first clamping protrusion to the second clamping protrusion point to the notch of the connecting groove, so that the abutment force applied by the second clamping protrusion to the first clamping protrusion points to the bottom of the connecting groove, thereby preventing the annular clamping part from detaching from the connecting groove.

[0021] In some embodiments of the present application, a first guide surface is provided on the side of the annular clamping portion facing the bottom of the connecting groove, and an extension direction of the first guide surface is along the annular clamping portion pointing toward the sealing body and away from the annular clamping portion; a second guide surface is provided on the side of the second clamping protrusion facing the notch of the connecting groove, and an extension direction of the second guide surface is the same as an extension direction of the first guide surface.

[0022] With such arrangement, when the annular clamping portion is inserted into the connecting groove, the first guide surface can slide along the second guide surface, so that the annular clamping portion can be inserted into the connecting groove more smoothly.

[0023] In some embodiments of the present application, the annular clamping portion and the sealing body are an integral structure.

[0024] Such arrangement can improve the connection strength between the annular clamping part and the sealing body, thereby improving the structural reliability of the sealing ring. Moreover, the annular clamping part and the sealing body can be formed in one piece by injection molding or other methods, thereby reducing the difficulty of processing the sealing ring.

[0025] In some embodiments of the present application, the refrigeration compartment includes a separate article storage section and an equipment storage section, and the article storage section is closer to the refrigeration door body than the equipment storage section; the first air duct includes a first air inlet channel and a first return air channel that are spaced apart, and the first air inlet channel and the first return air channel are both connected to the equipment storage section; the first air inlet channel forms a first air inlet on the surface of the article storage section; the first return air channel forms a first return air outlet on the surface of the article storage section, and the first return air outlet and the first air inlet form the first air outlet.

[0026] In this way, by setting the first air inlet channel and the first return air channel at intervals, the air inlet path and the return air path can be separated to prevent heat exchange between the return air path with a higher temperature and the air inlet path with a lower temperature, thereby reducing cooling loss.

[0027] In some embodiments of the present application, the second air duct includes a second air inlet channel and a second air return channel arranged at intervals, and the second air inlet channel and the second return air channel are both connected to the ice making compartment; the second air inlet channel forms a second air inlet on the surface of the refrigeration door body; the second return air channel forms a second return air outlet on the surface of the refrigeration door body, and the second return air outlet and the second air inlet form the second air outlet.

[0028] In this way, by setting the first air inlet channel and the first return air channel at intervals, the air inlet path and the return air path can be separated to prevent heat exchange between the return air path with a higher temperature and the air inlet path with a lower temperature, thereby reducing cooling loss.

[0063] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0064] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0065] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0066] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0067] The terms "first", "second" and the like are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined with "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0068] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0069] In related technologies, such as Fig.10 As shown, the second air duct 110' forms a second air inlet 111' on the side wall of the refrigeration door body 100', and a connecting groove 120' surrounding the second air inlet 111' is provided on the outer side of the side wall of the refrigeration door body 100'. At least one clamping protrusion 130' is provided on the two opposite side walls of the connecting groove 120'. The sealing ring 200' includes a sealing body 210' and an annular clamping portion 220' connected to the sealing body 210'. The annular clamping portion 220' is inserted into the connecting groove 120' and is mutually clamped with the clamping protrusion 130'. The sealing body 210' includes a fixed end 211' and a movable end 212' arranged opposite to each other. The fixed end 211' is connected to the annular clamping portion 220' and is away from the second air inlet 111'. The movable end 212' is close to the second air inlet 111', and has a gap 213' between it and the side wall of the refrigeration door body 100'.

[0070] However, the above sealing ring has a technical problem of poor sealing performance. The inventors have found that the reason is: Fig.10 As shown by the small and medium arrows, since there is a gap 213' between the movable end 212' and the refrigeration door body 100', the air in the second air duct 110' will pass through the gap 213' and enter between the annular clamping portion 220' and the side wall of the connecting groove 120'. If the fixed end 211' and the side wall of the refrigeration door body 100' are not tightly fitted, air will easily flow out between the fixed end 211' and the side wall of the refrigeration door body 100', resulting in poor sealing performance of the sealing ring, thereby causing a technical problem of cold leakage.

[0071] In view of this, the refrigerator in the embodiment of the present application is provided with a sealing ring, which has an extension portion at its movable end that extends into the second air duct. The extension portion can block the air in the second air duct and extend the leakage path of the air in the second air duct, thereby reducing the amount of air entering between the annular clamping portion and the side wall of the connecting groove, thereby reducing the amount of air flowing out from between the fixed end and the side wall of the refrigeration door body, improving the sealing performance of the sealing ring, and further reducing the amount of leaked cold.

[0072] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] refer to Figure 1 and Figure 2 , an embodiment of the present application provides a refrigerator, which may include a box body 100 and a refrigeration door body 200. The box body 100 may be configured with a refrigeration compartment 110. Exemplarily, the box body 100 may include a box shell 120 and a box liner 130, and the box shell 120 is used to define the outer boundary of the refrigerator. The box liner 130 is arranged in the box shell 120 and may be configured with a refrigeration compartment 110. The refrigeration compartment 110 can be used to place items such as food. The number of refrigeration compartments 110 may be one or more. Multiple refrigeration compartments 110 may be divided into a refrigeration compartment, a temperature-changing chamber, a freezing compartment, etc. The refrigeration compartment, the temperature-changing chamber, and the freezing compartment may be arranged from top to bottom along the height direction of the box body 100. The refrigeration compartment 110 may also include a separate article storage portion and an equipment storage portion. For example, a partition 131 may be provided in the refrigerator, and the partition 131 may be parallel to the rear side wall of the box liner 130 and connected to the box liner 130 to separate the refrigerator into an item storage portion and an equipment storage portion. The item storage portion may be closer to the refrigeration door 200 than the equipment storage portion, so as to facilitate taking and placing items from the item storage portion, thereby improving the convenience of using the refrigerator. The item storage portion may be used to store items. The equipment storage portion may be used to install other parts of the refrigerator.

[0074] The refrigeration door body 200 is rotatably connected to the cabinet 100 and is used to open or close the refrigeration compartment 110. One refrigeration door body 200 may be provided corresponding to the same refrigeration compartment 110. Alternatively, two refrigeration door bodies 200 may be provided corresponding to the same refrigeration compartment 110. Exemplarily, the refrigeration door body 200 may include a door shell 210 and a door liner 220. The door shell 210 is rotatably connected to the cabinet 100. The door liner 220 may be connected to a side of the door shell 210 facing the cabinet 100 when the refrigeration door body 200 is closed.

[0075] refer to Figure 3 The refrigerator of the embodiment of the present application may also include a refrigeration system and a driving fan (not shown in the drawings), and the refrigeration system is used to provide cold capacity. At least part of the refrigeration system and the driving fan may be installed in the equipment storage part. Exemplarily, the refrigeration system may include a compressor, a condenser, a capillary tube and an evaporator. The compressor is used to compress the refrigerant vapor to generate high-temperature and high-pressure vapor, and transport the refrigerant vapor to the condenser. The condenser is used to liquefy the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant cold liquid, and transport the refrigerant cold liquid to the capillary tube. After the capillary tube reduces the pressure of the refrigerant cold liquid, the high-pressure and low-temperature liquid is converted into a low-pressure and low-temperature refrigerant, and the low-pressure and low-temperature refrigerant is transported to the evaporator. After receiving the low-pressure and low-temperature refrigerant, the evaporator boils it under isobaric conditions, absorbs heat and vaporizes it to generate cold capacity. The driving fan drives the air to flow, carrying at least part of the cold capacity generated by the refrigeration system from the equipment storage part into the item storage part to cool the items.

[0076] refer to Figure 4 The refrigerator of the embodiment of the present application may also include an ice-making device 300, which is used to generate and output ice to meet the user's ice needs and improve the user experience. Exemplarily, the refrigeration door body 200 may be configured with an ice-making compartment 230. For example, the side of the door liner 220 facing away from the door shell 210 may be configured with an ice-making compartment 230. The door liner 220 may also be connected to an ice-making door body 231, which is used to open or close the ice-making compartment 230. The ice-making device 300 may be arranged in the ice-making compartment 230 to reduce the space volume of the article storage part occupied by the ice-making device 300, thereby increasing the article capacity of the refrigerator.

[0077] Exemplarily, the ice making device 300 may include an ice maker 310 and an ice storage bucket 320. The ice maker 310 is used to produce ice, and the ice storage bucket 320 is located below the ice maker 310. The ice storage bucket 320 has an upper opening for holding ice separated from the ice maker 310. In some possible implementations of the embodiment of the present application, the ice making device 300 may also include a dispenser 330, which is used to allow the user to take ice from the outside of the refrigerator without opening the refrigeration door body 200, thereby improving the convenience of the user when using ice. Exemplarily, the dispenser 330 may be arranged on the side of the door housing 210 facing away from the door liner 220. The bottom side of the ice making compartment 230 may be provided with an ice outlet, and the ice outlet may be connected to the dispenser 330. The ice storage bucket 320 has a lower opening, and an ice delivery assembly is disposed in the ice storage bucket 320, which can deliver the ice in the ice storage bucket 320 in the form of complete ice cubes or crushed ice from the lower opening of the ice storage bucket 320. The delivered ice enters the dispenser 330 through the first ice outlet.

[0078] The cold capacity required by the ice-making device 300 can be provided by the refrigeration system. Exemplarily, a first air duct may be provided inside the box 100. For example, the first air duct may be provided between the box shell 120 and the box liner 130. The first air duct may form a first air outlet on the surface of the refrigeration compartment 110. A second air duct may be provided inside the refrigeration door body 200. For example, the second air duct may be provided between the door shell 210 and the door liner 220. The second air duct is connected to the ice-making compartment 230. The second air duct may form a second air outlet on the surface of the refrigeration door body 200. When the refrigeration door body 200 is closed, the first air outlet is connected to the second air outlet so that the first air duct and the second air duct are connected, so that heat exchange can be performed between the ice-making compartment 230 and the refrigeration compartment 110, and at least part of the cold capacity generated by the refrigeration system can be provided to the ice-making device 300.

[0079] Exemplarily, the first air duct may include a first air inlet channel 140 and a first air return channel 150 which are arranged at intervals, and the first air inlet channel 140 and the first air return channel 150 are both connected to the equipment storage part. The first air inlet channel 140 forms a first air inlet 141 on the surface of the article storage part. The first air return channel 150 forms a first air return port 151 on the surface of the article storage part, and the first air return port 151 and the first air inlet 141 form a first air port. The wind generated by the driving fan enters the first air inlet channel 140 from the equipment storage part, then enters the second air duct from the first air inlet 141 and the second air port of the refrigeration door body 200, and then enters the ice making compartment 230 to form an air inlet path. The air inlet path can carry at least part of the cold energy generated by the refrigeration system into the ice making compartment 230 to provide cold energy for the ice making device 300. After providing cold air for the ice-making device 300, the air inlet path is heated up, enters the second air duct, enters the first return air channel 150 through the second air port and the first return air port 151, and then returns to the equipment storage part to form a return air path. By setting the first air inlet channel 140 and the first return air channel 150 at intervals, the air inlet path and the return air path can be separated to prevent heat exchange between the return air path with a higher temperature and the air inlet path with a lower temperature, thereby reducing the loss of cold air.

[0080] For example, reference Figure 3The second air duct may include a second air inlet channel 240 and a second air return channel 250 arranged at intervals, and the second air inlet channel 240 and the second air return channel 250 are both connected to the ice making compartment 230. The second air inlet channel 240 forms a second air inlet 241 on the surface of the refrigeration door body 200. The second air return channel 250 forms a second air return port 251 on the surface of the refrigeration door body 200, and the second air return port 251 and the second air inlet 241 form a second air port. When the refrigeration door body 200 is closed, the second air inlet 241 may be connected to the first air inlet 141, and the second air return port 251 may be connected to the first air return port 151. The air inlet path may enter the second air inlet channel 240 through the first air inlet 141 and the second air inlet 241 connected to each other, and then enter the ice making compartment 230. The return air path can enter the second return air passage 250 from the ice making room 230, and enter the first return air passage 150 through the second return air port 251 and the first return air port 151 connected to each other, and then return to the equipment storage part. By setting the first air inlet passage 140 and the first return air passage 150 at intervals, the inlet air path and the return air path can be separated, preventing the return air path with a higher temperature from exchanging heat with the inlet air path with a lower temperature, thereby reducing the loss of cooling capacity.

[0081] The refrigerator of the embodiment of the present application further includes a sealing ring 400, which is configured to seal the first air outlet and the second air outlet when the refrigeration door 200 is closed to prevent cold leakage. Figure 4 and Figure 5 As shown, a connection groove 260 may be provided on one side of the refrigeration door body 200 having the second air outlet, and the connection groove 260 may be spaced apart from the second air outlet and surround the second air outlet. The sealing ring 400 may be detachably connected to the connection groove 260. The user may remove the sealing ring 400 for cleaning to prevent the sealing ring 400 from depositing stains and bacteria, thereby improving the safety of the refrigerator.

[0082] Exemplarily, there may be two connecting grooves 260, and the two connecting grooves 260 may be respectively arranged corresponding to the second air inlet 241 and the second air return outlet 251. There may be two sealing rings 400, one of which is used to seal the first air inlet 141 and the second air inlet 241, and the other sealing ring 400 is used to seal the first air return outlet 151 and the second air return outlet 251. The technical solution of the embodiment of the present application is described below by taking the sealing ring 400 that seals the first air inlet 141 and the second air inlet 241 as an example.

[0083] For example, reference Figure 6 , Figure 7 , Figure 8 and Fig. 9, the sealing ring 400 may include an annular clamping portion 410 and a sealing body 420. The annular clamping portion 410 is clamped in the connecting groove 260. The sealing body 420 includes a fixed end 421 and a movable end 422 opposite to each other, and the fixed end 421 is connected to the annular clamping portion 410. The movable end 422 is closer to the second air outlet than the fixed end 421, for example, the movable end 422 is closer to the second air inlet 241. The movable end 422 may be connected to an extension portion 423, and the extension portion 423 extends into the second air duct, for example, the extension portion 423 may extend into the second air inlet channel 240. When the refrigeration door body 200 is closed, part of the door liner 220 extends into the article storage portion of the refrigeration compartment 110, and the second air inlet 241 is opposite to the first air inlet 141. The sealing ring 400 surrounds the first air inlet 141, and the sealing body 420 of the sealing ring 400 is squeezed by the side wall of the object storage portion and deformed, so that the sealing body 420 fits tightly with the door liner 220 and the side wall of the object storage portion, thereby realizing a sealed connection between the first air inlet 141 and the second air inlet 241.

[0084] In the refrigerator of the embodiment of the present application, the extension portion 423 can block the air in the second air inlet channel 240 and extend the leakage path of the air in the second air inlet channel 240, reducing the amount of air entering between the annular clamping portion 410 and the side wall of the connecting groove 260, thereby reducing the amount of air flowing out from between the fixed end 421 and the side wall of the refrigeration door body 200, improving the sealing performance of the sealing ring 400, and thereby reducing the amount of leaked cold.

[0085] like Figure 6 As shown, the annular clamping portion 410 may have a first side and a second side relative to each other, and the first side is farther away from the second air outlet than the second side. The sealing ring 400 may also include a first connecting portion 430 and a second connecting portion 440. The first connecting portion 430 connects the first side and the fixed end 421, and abuts against the refrigeration door body 200. The second connecting portion 440 is connected to the second side, and abuts against the refrigeration door body 200. By setting the first connecting portion 430 and the second connecting portion 440, the length of the fit between the sealing ring 400 and the refrigeration door body 200 is the sum of the fitting length between the first connecting portion 430 and the refrigeration door body 200 and the fitting length between the second connecting portion 440 and the refrigeration door body 200. In other words, the effective sealing length between the sealing ring 400 and the refrigeration door body 200 is L1+L2. However, as Fig.10 As shown, the effective sealing length between the sealing ring 200' and the refrigeration door body 100' in the related art is L1. Compared with the related art, the effective sealing length between the sealing ring 400 and the refrigeration door body 200 in the embodiment of the present application is longer and the sealing performance is better.

[0086] Exemplarily, the sealing body 420 and the first connecting portion 430, the annular clamping portion 410 and the second connecting portion 440 can be surrounded by a first deformation space 450 having an opening, and the opening is adjacent to the second air outlet. In this way, when the refrigeration door body 200 is closed, the refrigeration door body 200 squeezes the sealing body 420, which can increase the deformation of the sealing body 420, thereby increasing the contact area between the sealing body 420 and the side wall of the refrigeration chamber 110, and improving the reliability of the sealing connection between the first air inlet 141 and the second air inlet 241.

[0087] Exemplarily, a second deformation space 460 may be provided in the annular clamping portion 410, and the second deformation space 460 is communicated with the first deformation space 450. By providing the second deformation space 460 in the annular clamping portion 410, when the annular clamping portion 410 is inserted into the connecting groove 260, the groove wall of the connecting groove 260 squeezes the annular clamping portion 410, which can increase the deformation amount of the annular clamping portion 410, thereby increasing the contact area between the annular clamping portion 410 and the groove wall of the connecting groove 260, improving the connection strength between the annular clamping portion 410 and the groove wall of the connecting groove 260, and preventing the annular clamping portion 410 from detaching from the connecting groove 260.

[0088] Continue to refer Figure 8 and Fig. 9 The annular clamping portion 410 may have a first clamping protrusion 411 on one side facing the groove wall of the connecting groove 260. The side wall of the connecting groove 260 may be provided with a second clamping protrusion 261, and the side of the second clamping protrusion 261 facing away from the notch of the connecting groove 260 abuts against the side of the first clamping protrusion 411 facing the sealing body 420. By providing the first clamping protrusion 411 and the second clamping protrusion 261 abutting against each other, the connection strength between the annular clamping portion 410 and the groove wall of the connecting groove 260 can be improved to prevent the annular clamping portion 410 from being separated from the connecting groove 260. Exemplarily, the two opposite side walls of the connecting groove 260 are provided with the second clamping protrusion 261, and the two sides of the annular clamping portion 410 facing the two groove walls are provided with the first clamping protrusion 411 to further improve the connection strength between the annular clamping portion 410 and the groove wall of the connecting groove 260.

[0089] Exemplarily, the extension direction of the first clamping protrusion 411 may be directed toward the sealing body 420 and away from the annular clamping portion 410 along the annular clamping portion 410. In this way, the abutting force applied by the first clamping protrusion 411 to the second clamping protrusion 261 may be directed toward the notch of the connecting groove 260, thereby causing the abutting force applied by the second clamping protrusion 261 to the first clamping protrusion 411 to be directed toward the groove bottom of the connecting groove 260, thereby preventing the annular clamping portion 410 from being separated from the connecting groove 260.

[0090] Exemplarily, a first guide surface 412 may be provided on one side of the annular clamping portion 410 facing the groove bottom of the connecting groove 260, and the extension direction of the first guide surface 412 points to the sealing body 420 along the annular clamping portion 410 and away from the annular clamping portion 410. A second guide surface 262 may be provided on one side of the second clamping protrusion 261 facing the notch of the connecting groove 260, and the extension direction of the second guide surface 262 is the same as the extension direction of the first guide surface 412. When the annular clamping portion 410 is inserted into the connecting groove 260, the first guide surface 412 may slide along the second guide surface 262, so that the annular clamping portion 410 can be inserted into the connecting groove 260 more smoothly.

[0091] For example, the annular clamping portion 410 and the sealing body 420 may be an integral structure. This arrangement can improve the connection strength between the annular clamping portion 410 and the sealing body 420, thereby improving the structural reliability of the sealing ring 400. Moreover, the annular clamping portion 410 and the sealing body 420 may be formed in an integral molding manner such as injection molding, thereby reducing the difficulty of processing the sealing ring 400.
