DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the air duct connection assembly and connector of the range hood of the present invention are specifically described below in combination with embodiments and drawings.

[0028] <Example 1>

[0029] Figure 1 This is one of the structural diagrams of the air duct connection assembly of the utility model.

[0030] Figure 2 It is a structural explosion diagram of the air duct connection assembly of the utility model.

[0031] This embodiment provides a range hood air duct connection assembly 100, which is used to be installed on the range hood body to absorb and exhaust oil fumes. Figure 1 and Figure 2 As shown, the air duct connection assembly 100 includes a connector 10, an exhaust duct 20 and a sealing member 30. One end of the connector 10 is fixedly mounted on the body of the range hood by bolts or screws, and the other end cooperates with the exhaust duct 20 to connect it to the exhaust duct 20. The sealing member 30 is clamped between the exhaust duct 10 and the connector 20, thereby installing the exhaust duct 20 on the body.

[0032] Figure 3 It is a front view of the connector of the utility model.

[0033] Figure 4 It is a stereogram of the connector of the utility model.

[0034] like Figure 3 and Figure 4As shown, the connector 10 includes a connecting portion 11, a mounting portion 12 and a guide portion 13. The connecting portion 11 is used to connect to the exhaust duct 20, the mounting portion 12 is used to be fixed to the body, and a slot 14 for inserting the exhaust duct 20 is provided between the guide portion 13 and the connecting portion 11. The mounting portion 12 is a rectangular plate-like structure with rounded corners, having a pair of long sides parallel to each other and a pair of short sides parallel to each other. Mounting holes are provided at the four corners of the mounting portion 12 for fixing to the body by bolts or screws. The middle part of the mounting portion 12 is protruded toward one side to form a connecting portion 11, and guide portions 13 are formed on both sides of the connecting portion 11. Among them, the connecting portion 11 is also in the shape of a rectangular ring with rounded corners as a whole, and there are two guide portions 13, which are respectively located on the short sides of the mounting portion 12, that is, located on the left and right sides of the connecting portion 11 in the figure (in the width direction of the rectangle). The connecting portion 11 comprises a main body portion 111 and an abutting portion 112. The main body portion 111 is used to be inserted into the exhaust pipe 20. The abutting portion 112 comprises an abutting surface 113 protruding from the main body portion. The abutting surface 113 is used to abut against the end surface of the exhaust pipe 20. That is to say, the abutting surface 113 is also the bottom of the slot 14. When installing the exhaust pipe 20, it can be directly inserted into the slot 14 beside the guide portion 13, which is very convenient and quick.

[0035] Figure 5 A cross-sectional view of an air duct connection assembly of the utility model.

[0036] Figure 6 yes Figure 5 A partial enlarged view of point A.

[0037] like Figure 3 and Figure 4 As shown, the guide portion 13 is provided with a limiting protrusion 131, and the limiting protrusion 131 is used to cooperate with the abutting surface 113 to limit the exhaust pipe 20 inserted into the slot 14. Figure 5 and Figure 6 The limiting protrusion 131 is an elastic block, one end of which is connected to the guide part 13, and the other end is suspended so that the limiting protrusion 131 has a certain elasticity, and a guiding inclined surface 132 is provided on the side of the elastic block facing the slot 14. When the exhaust pipe 20 is inserted into the slot 14, the end face of the exhaust pipe 20 is first inserted along the guiding inclined surface 132. Under the action of the exhaust pipe 20, the elastic block will slightly swing toward the side where the guide part 13 is located, so that the exhaust pipe 20 can be inserted into the slot 14. When the end face of the exhaust pipe 20 is attached to the abutting surface 113, the limiting protrusion 131 is reset to abut against the exhaust pipe 20. The limiting protrusion 131 and the abutting surface 113 form a limit for the front and rear ends of the exhaust pipe 20, thereby limiting the exhaust pipe 20 between the limiting protrusion 131 and the abutting surface 113, preventing the exhaust pipe 20 from being separated from the connector 10, and ensuring the stability of the connection structure.

[0038] Figure 7 This is the second structural diagram of the air duct connection assembly of the utility model.

[0039] The connector 10 further includes a blocking portion 15, which is in a long strip structure, one end of which is connected to the long side of the mounting portion 12, and the other end protrudes from the abutting portion 112, so that a gap is formed between the blocking portion 15 and the main body portion 111 for inserting the exhaust pipe 20, and the gap is also part of the slot 14. In this embodiment, Figure 7 As shown, two blocking parts 15 are provided and located on the side of the mounting part in the length direction, which can be used to block the long side of the exhaust pipe 20 in the length direction to prevent the exhaust pipe from bulging after being compressed and affecting the sealing effect.

[0040] Figure 8 It is a structural diagram of the exhaust duct of the utility model.

[0041] like Figure 8 As shown, the exhaust pipe 20 comprises: a pipe body portion 21, a plug-in portion 22 and a clamping portion 23. Figure 5 and Figure 6 As shown, the plug-in portion 22 is formed with one end of the tube portion 21 and is used to be inserted into the slot 14. The clamping portion 23 is used to be clamped on the end of the main portion 111 away from the abutting portion 112. The sealing member 30 is provided between the clamping portion 23 and the main portion 111. A limiting surface 24 protruding from the outer surface of the tube portion 21 is also provided between the plug-in portion 22 and the tube portion 21. When the exhaust pipe 20 is installed on the connector 10, as shown in FIG. Figure 5 and Figure 6 As shown, one end surface ( Figure 5 The lower end surface of the plug-in portion 22 is in contact with the abutment surface 113 of the abutment portion 112, and the other end surface ( Figure 5 The upper end surface of the plug-in connector (also the limiting surface 24) abuts against the limiting protrusion 131, so that the plug-in portion 22 is limited between the limiting protrusion 131 and the abutting surface 113. In this embodiment, the limiting protrusion 131 abuts against the limiting surface 24. In actual situations, the limiting protrusion 131 may not abut against the limiting surface. As long as the distance between the bottom of the limiting protrusion 131 and the abutting surface 113 is greater than the length of the plug-in portion 22, the plug-in portion 22 can be prevented from being disengaged.
