Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a modular split-type sealing connection device and a range hood. Background Technology

[0002] A range hood typically includes a smoke inlet assembly and a fan assembly connected above it. The fan assembly is internally divided into a smoke collection chamber and a smoke-free chamber that is not connected to the smoke collection chamber. The fan is located in the smoke collection chamber, while the control circuit board is installed in the smoke-free chamber to achieve oil and electricity separation. The smoke inlet assembly usually has a retractable smoke gathering plate and lighting components. The smoke inlet assembly and the fan assembly are usually connected by a set of connectors, with one having a male connector and the other having a female connector. The connectors are used to provide power and data communication to the smoke inlet assembly, reducing the structural complexity caused by directly routing wires to the smoke inlet assembly.

[0003] However, the existing technology of using connectors to connect the smoke inlet assembly and the fan assembly has the following shortcomings: the oil fumes sucked into the smoke inlet assembly can easily leak into the smokeless chamber of the range hood through the connector, making it difficult to truly achieve zero oil fume leakage in the smokeless chamber; at the same time, the vibration generated by the fan during long-term use of the range hood can easily cause the male and female connectors to loosen, affecting the reliability of operation. Utility Model Content

The second connecting component 2 includes a plug seat 22 with a receiving cavity and a second mating part 25 disposed in the receiving cavity. It also includes a sealing device 13 disposed between the plug 12 and the plug seat 22. The second connecting component 2 also includes a floating seat 24 limited in the receiving cavity by a floating structure, and the second mating part 25 is fixed to the end of the floating seat 24. When the first connecting component 1 and the second connecting component 2 are plugged and connected, the plug 12 is inserted into the plug seat 22, the sealing device 13 forms a seal between the plug 12 and the plug seat 22, and the floating structure generates a floating force on the floating seat 24 in the direction of the first connecting component 1, so that the first mating part 14 and the second mating part 25 are kept coupled and connected.

[0006] In some embodiments, the insertion end of the connector 12 is provided with an outer inclined surface 121, and the cavity of the connector 22 is provided with an inner inclined surface 221.

[0007] In some embodiments, the sealing device (13) is sleeved on the outer wall of the plug (12) or fixed on the inner wall of the receiving cavity; a plurality of protrusions 122 are provided at intervals around the plug 12, the protrusions 122 abut against the inner wall of the receiving cavity, and a sealing gap is formed between the plug 12 and the plug seat 22.

[0008] In some embodiments, the sealing device 13 has a plurality of spaced annular deformation portions 131 on its outer side, and the end of each annular deformation portion 131 is arranged perpendicularly or obliquely relative to the central axis of the connector 12.

[0009] In some embodiments, the plug socket 22 further includes a first fixing seat 220 located on the outer side of the receiving cavity, and a fixed connection is formed between the first fixing seat 220 and the second mounting plate 21 for fixing the plug connector 12 within a preset gap range.

[0010] In some embodiments, the first fixing base 220 is provided with a movable through hole 222, and the second mounting plate 21 is provided with a corresponding second fixing hole 211. The second fixing member 29 passes through the movable through hole 222 and is fixedly connected to the second fixing hole 211, forming a preset gap between the hole wall of the movable through hole 222 and the second fixing member 29.

[0011] In some embodiments, the floating seat 24 includes a second wiring cavity 240 and a set of second fixed seats 241 located on the outer side of the second wiring cavity 240, and the floating structure is disposed between the second fixed seats 241 and the plug seat 22.

[0012] In some embodiments, the floating structure includes a limiting rod 28 that limits the floating seat 24 within the receiving cavity and an elastic member 23 disposed between the floating seat 24 and the insertion seat 22 to generate a floating force on the floating seat 24.

[0013] In some embodiments, a first anti-foolproof structure is provided between the connector 12 and the socket 22; or / and a second anti-foolproof structure is provided between the first mating portion 14 and the second mating portion 25.

[0014] This utility model also discloses a range hood, including a smoke inlet assembly and a fan assembly, and also includes the aforementioned modular split-type sealing connection device. The first connection component 1 is fixed on the smoke inlet assembly, and the second connection component 2 is fixed on the fan assembly. The smoke inlet assembly and the second module form a wired communication connection or a wireless communication connection using the aforementioned modular split-type sealing connection device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The first connecting component 1 and the second connecting component 2 adopt a modular split design. By adding a sealing device 13 to the outer side of the plug 12 of the first connecting component 1, when the plug 12 is inserted into the receiving cavity of the plug seat 22, the sealing device 13 forms a sealed connection between the plug 12 and the plug seat 22, ensuring that the sealing connection device has reliable sealing performance that is waterproof and oil-proof. At the same time, by adding a floating structure in the second connecting component 2, the floating seat 24 is limited and positioned in the receiving cavity of the plug seat 22 by the floating structure. The floating structure generates a floating force on the floating seat 24 in the direction of the first connecting component 1, which helps to keep the first mating part 14 and the second mating part 25 coupled and less likely to loosen due to external interference, thereby further improving the connection reliability of the sealing connection device.

[0026] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0027] Combination Figures 1-7 As shown, this utility model discloses a modular split-type sealing connection device, including a first connecting component 1 and a second connecting component 2 that can be plugged into each other. The first connecting component 1 includes a plug 12, a sealing device 13 sleeved on the outer side of the plug 12, and a first mating portion 14 located at the end of the plug 12. The second connecting component 2 includes a plug seat 22 with a receiving cavity, a floating seat 24 limited in the receiving cavity by a floating structure, and a second mating portion 25 disposed in the receiving cavity and fixed to the end of the floating seat 24. When the first connecting component 1 and the second connecting component 2 are plugged into each other, the plug 12 is inserted into the plug seat 22, the sealing device 13 forms a seal between the plug 12 and the plug seat 22, and the floating structure generates a floating force on the floating seat 24 toward the first connecting component 1, so that the first mating portion 14 and the second mating portion 25 are kept coupled.

[0028] In addition to being sleeved on the outer side of the plug 12, the sealing device 13 can also be fixed on the inner side wall of the receiving cavity of the plug seat 22, and can even be set between the end face of the plug 12 and the end face of the second mating part 25.

[0029] The sealing device 13 forms a seal between the plug 12 and the socket 22, including forming a seal between the contact surfaces of the plug 12 and the socket 22 in the opposite insertion direction, and / or forming a seal between the end face of the plug 12 and the end face of the second mating portion 25, which is not limited thereto.

[0030] By adding a sealing device 13 to the outer side of the plug 12 of the first connecting assembly 1, when the plug 12 is inserted into the receiving cavity of the plug seat 22, the sealing device 13 forms a sealed connection between the plug 12 and the plug seat 22, ensuring that the sealing connection device has reliable sealing performance that is waterproof and oil-proof. At the same time, by adding a floating structure in the second connecting assembly 2, the floating seat 24 is limited and positioned in the receiving cavity of the plug seat 22 by the floating structure. The floating structure generates a floating force on the floating seat 24 in the direction of the first connecting assembly 1, which helps to keep the first mating part 14 and the second mating part 25 coupled and less likely to loosen due to external interference, thereby further improving the connection reliability of the sealing connection device.

[0031] The insertion end of the connector 12 is provided with an outer inclined surface 121, and the cavity of the connector 22 is provided with an inner inclined surface 221. The connector 22 uses the inner inclined surface 221 to provide an insertion guide for the outer inclined surface 121 of the connector 12, making it easier to insert the connector 12 of the first connecting assembly 1 into the connector 22.

[0032] The connector 22 also includes a first fixing seat 220 located on the outer side of the receiving cavity, which forms a movable fixed connection with a second mounting plate 21 for fixing the connector 12 within a preset gap range. The second mounting plate 21 can be a component of the first connecting assembly 1 or a component used to fix the connector 12 in the usage scenario of the first connecting assembly 1, and is not limited here.

[0033] The first fixing base 220 has a movable through hole 222, and the second mounting plate 21 has a corresponding second fixing hole 211. The second fixing member 29 passes through the movable through hole 222 and is fixedly connected to the second fixing hole 211, forming a preset gap between the hole wall of the movable through hole 222 and the second fixing member 29. That is, the diameter of the second fixing hole 211 is larger than the outer diameter of the second fixing member 29 located inside the movable through hole 222, thereby forming a preset gap between the hole wall of the movable through hole 222 and the second fixing member 29.

[0034] The advantage of setting a fixed connection between the connector 12 and the second mounting plate 21 that is movable within a preset gap range is that when the first connecting component 1 and the second connecting component 2 are plugged in, the floating connection between the connector 12 and the second mounting plate 21 that is movable within a preset gap range can quickly correct the misalignment gap between the connector 12 and the socket 22, ensuring that the connector 12 can be quickly inserted into the socket 22.

[0035] The floating seat 24 includes a second wiring cavity 240 and a set of second fixed seats 241 located on the outer side of the second wiring cavity 240. The floating structure is disposed between the second fixed seats 241 and the plug-in seat 22. The floating structure includes a limiting rod 28 that limits the floating seat 24 within the receiving cavity and an elastic member 23 disposed between the floating seat 24 and the plug-in seat 22 to generate a floating force on the floating seat 24.

[0036] For example, the elastic element 23 is a compression spring, which is sleeved on the limiting rod 28 and located between the second fixed seat 241 and the bottom of the receiving cavity. The compression spring generates a floating force on the floating seat 24 in the direction of the cavity opening, pushing the floating seat 24 to move towards the first docking part 14, thereby correcting any gaps that may exist between the first docking part 14 and the second docking part 25, and ensuring that the first docking part 14 and the second docking part 25 maintain a reliable coupling connection and are not prone to loosening.

[0037] An annular groove 125 is provided on the outer side of the connector 12, and the sealing device 13 is sleeved in the annular groove 125, so that when the connector 12 is inserted into the receiving cavity of the connector 22, the sealing device 13 will not move accordingly with the insertion of the connector 12, ensuring that the sealing device 13 can form a reliable sealing fit between the connector 12 and the connector 22.

[0038] In addition, the outer side of the sealing device 13 has a plurality of spaced annular deformation portions 131, the end of each annular deformation portion 131 being perpendicular or inclined relative to the central axis of the plug 12. During the process of inserting the plug 12 into the receiving cavity of the plug seat 22, the end of each annular deformation portion 131 contacts the inner wall of the receiving cavity and deforms in the opposite direction of insertion. The cooperation of the plurality of annular deformation portions 131 ensures a reliable sealing connection between the plug 12 and the inner wall of the receiving cavity of the plug seat 22.

[0039] When the sealing device 13 is sleeved on the outer wall of the connector 12 or fixed on the inner wall of the receiving cavity, in order to avoid uneven local stress on the sealing device 13 and failure of the sealing device 13 after the connector 12 is adjusted and aligned with the connector seat 22 based on a preset gap, the present invention provides a plurality of protrusions 122 at intervals on the periphery of the connector 12. The protrusions 122 abut against the inner wall of the receiving cavity. The plurality of protrusions 122 cooperate to form a sealing gap between the connector 12 and the connector seat 22. The sealing gap provides a preset deformation space for the sealing device 13, ensuring that the sealing device 13 forms a reliable sealing connection between the connector 12 and the connector seat 22.

[0040] Furthermore, in combination Figures 7-9 As shown, the specific implementation of the limit rod 28 is not limited. Figure 7 As shown, the limiting rod 28 is a limiting post with a shrinkage groove on the top cap. The bottom end of the limiting post is fixed to the bottom of the receiving cavity of the plug-in seat 22. When the limiting hole 242 of the second fixed seat 241 of the floating seat 24 is pressed into the limiting rod 28 from top to bottom, the inner wall of the limiting hole 242 squeezes the top cap of the limiting rod 28, causing the shrinkage groove to shrink so that the top cap can pass through the limiting hole 242 upwards, allowing the second fixed seat 241 to be sleeved on the limiting rod 28 to achieve limiting assembly.

[0041] like Figure 8 As shown, the top of the limiting rod 28 is provided with a buckle, and the inner wall of the limiting hole 242 is provided with a spring piece. When the limiting hole 242 of the second fixed seat 241 of the floating seat 24 is aligned with the limiting rod 28 and pressed down for assembly, the buckle squeezes the spring piece and deforms, allowing the buckle to pass upward through the limiting hole 242. Then, the spring piece on the inner wall of the limiting hole 242 limits the bottom end of the buckle, preventing the second fixed seat 241 of the floating seat 24 from coming off the buckle of the limiting rod 28.

[0042] like Figure 9 As shown, the limiting rod 28 is a limiting screw. After passing through the limiting hole 242 of the second fixed seat 241 of the floating seat 24, the limiting screw is threaded and fixed to the bottom of the receiving cavity of the plug seat 22, so that the second fixed seat 241 of the floating seat 24 cannot be pulled upward out of the top nut of the limiting screw.

[0043] The first docking part 14 has a protruding first coupling part 141, and the first coupling part 141 has a plurality of electrical sockets 142. The plug 12 is fixed on the first mounting plate 11. For example, the first mounting plate 11 has a first fixing hole 111, and the first fixing member 19 passes through the first fixing hole 111 and is fixedly connected to the plug 12.

[0044] In addition, the first mounting plate 11 is provided with a first cable outlet hole 112, and the connector 12 has a first cable routing cavity 120 inside. The cable connected to the electrical socket 142 passes through the first cable routing cavity 120 and extends out from the first cable outlet hole 112.

[0045] To improve the waterproof and oil fume-proof performance of the sealing connection device, sealant can be injected into the first cable routing cavity 120 from the first cable outlet 112 to prevent water and oil fumes from entering along the cable, and also to prevent the cable from becoming loose from the electrical socket 142.

[0046] Correspondingly, the second docking part 25 is provided with a recessed second coupling part 251 and a plurality of electrical plugs 252 disposed in the second coupling part 251.

[0047] When the first docking part 14 and the second docking part 25 are coupled together, the first coupling part 141 is inserted into the second coupling part 251, and each electrical plug 252 is plugged into the corresponding electrical socket 142.

[0048] Correspondingly, the cable of the electrical plug 252 passes through the second wiring cavity 240 and exits from the second outlet hole 212 reserved on the second mounting plate 21. Of course, the second wiring cavity 240 can also be sealed with potting compound as needed.

[0049] In addition, to ensure accurate insertion of the first connecting component 1 and the second connecting component 2, a first anti-foolproof structure is provided between the plug 12 and the plug socket 22; or / and, a second anti-foolproof structure is provided between the first mating part 14 and the second mating part 25.

[0050] The first anti-foolproof structure includes an anti-foolproof protrusion on one side of the connector 12 and an anti-foolproof recess on the inner wall of the connector 22. The connector 12 can only be inserted into the connector 22 when the anti-foolproof protrusion of the connector 12 and the anti-foolproof recess of the connector 22 are roughly aligned.

[0051] The second foolproof structure includes setting one end of the first coupling portion 141 to a first shape and the other end to a second shape, for example, setting one end of the first coupling portion 141 to a circle and the other end to a square; the two ends of the second coupling portion 251 have shapes that correspond to and match the first coupling portion 141.

[0052] This utility model also discloses a range hood, including a smoke inlet assembly and a fan assembly, wherein the smoke inlet assembly and the fan assembly are connected by the aforementioned modular split-type sealed connection device. Specifically, a first connecting component 1 is fixed to the smoke inlet assembly, and a second connecting component 2 is fixed to the fan assembly. The smoke inlet assembly and the second module form a wired communication connection or a wireless communication connection using the aforementioned modular split-type sealed connection device.

[0053] Typically, the second connecting component 2 is connected to the power supply and control circuit board inside the smokeless chamber of the fan assembly, while the first connecting component 1 is connected to the lighting and other electrical equipment and sensors inside the smoke inlet assembly. The first connecting component 1 and the second connecting component 2 achieve a reliable sealed connection, eliminating the need for wiring between the power supply and control circuit board inside the smokeless chamber and the smoke inlet assembly. This allows the control circuit board to establish a wired communication connection with the electrical equipment and sensors inside the smoke inlet assembly, enabling the smoke inlet assembly and the fan assembly to adopt a modular design and independent assembly. It also ensures that the fumes entering the smoke inlet assembly will not leak into the smokeless chamber of the fan assembly.

[0054] Of course, in some embodiments, the control circuit board in the fan assembly has wireless communication function, and the smoke inlet assembly is also provided with a wireless communication module. The electrical equipment and sensors in the smoke inlet assembly are connected to the wireless communication module, so that the smoke inlet assembly can wirelessly connect with the control circuit board of the fan assembly through the wireless communication module. In this case, the sealed connection device is equivalent to a power socket, and it is only necessary to provide power to the smoke inlet assembly.

[0055] Of course, when it is a wireless communication connection, the first connection component 1 and the second connection component 2 are communication transceiver circuit components integrated by electronic components, which are respectively set in the smoke inlet component and the fan component in the form of components, or they can be integrated into the circuit board on the smoke inlet component and the circuit board on the fan component, respectively, which is not limited here.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
