Description

Technical Field

[0001] This utility model relates to the field of gas handling electrical appliances, and in particular to a split-type modular gas extraction and exhaust device. Background Technology

[0002] Taking range hoods as an example, existing split-type range hoods separate the main unit and the smoke collection hood, allowing them to be packaged and transported independently. This results in smaller packaging sizes and a smaller transport volume for each range hood, thus saving on transportation costs. In actual use, the main unit and smoke collection hood are assembled first, and then the range hood itself is assembled. Therefore, designing a reasonable assembly structure between the main unit and the smoke collection hood to simplify the assembly process and facilitate user assembly after purchasing the range hood is of great importance.

Detailed Implementation

[0043] 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.

[0044] like Figure 1 As shown, the gas extraction equipment includes a gas-gathering device 1 for drawing in gas and a main unit 2 that works in conjunction with the gas-gathering device 1. The gas-gathering device 1 and the main unit 2 are each designed as separate, modular units, allowing them to be packaged individually. Alternatively, an unlimited number of gas-gathering devices 1 and / or main units 2 can be packaged together in a single box with physical protection and isolation, making full use of the limited space in the box. By adopting a separate, modular, and independent design for the gas-gathering device 1 and the main unit 2, the packaging and transportation flexibility is greatly enhanced, allowing for smaller packaging sizes and saving on transportation costs.

[0045] The main unit 2 and the gas-gathering device 1 adopt a separate modular design, which allows the main unit 2 and the gas-gathering device 1 to be produced independently, packaged and transported separately, which can reduce the packaging size of a single unit and the transportation space occupied; in the end-use environment, the main unit 2 and the gas-gathering device 1 are then assembled into a complete unit.

[0046] The gas extraction equipment also includes a fan for providing gas suction to the gas gathering device and a separation and filtration assembly for separating and purifying the gas drawn into the gas gathering device 1. Both the fan and the separation and filtration assembly can be installed in the gas gathering device 1 and the main unit 2.

[0047] For example, the fan is installed inside the air-gathering device 1, while the separation and filtration assembly is installed inside the main unit 2. Alternatively, both the fan and the separation and filtration assembly are installed inside the air-gathering device 1. Yet another example is that both the fan and the separation and filtration assembly are installed inside the main unit 2.

[0048] Gas extraction and exhaust equipment has a wide range of applications. For example, an actual product is a range hood used to extract and exhaust cooking fumes, which is a type of kitchen appliance. Another example is an air purification device installed in public smoking rooms, offices, or even homes to extract and purify indoor air.

[0049] Gas extraction equipment is exemplified by a kitchen range hood. As is well known, the main unit 2 contains a fan and a separation and filtration assembly, while the gas-gathering device 1 mainly includes a smoke-collecting plate and an air intake channel. After assembling the main unit 2 and the gas-gathering device 1, the fan rotates during operation, creating negative pressure within the air intake channel. The smoke-collecting plate draws external cooking fumes into the air intake channel, where they are separated and filtered by the separation and filtration assembly. Finally, clean gas is discharged, reducing or even preventing cooking fumes from being inhaled by users or from being carelessly discharged, thus polluting the environment.

[0050] This application optimizes and improves the assembly structure of the main unit 2 and the gas-gathering device 1, so that the main unit 2 and the gas-gathering device 1 can be assembled into a complete unit more easily and quickly in the end-use environment, based on the separate design of the main unit 2 and the gas-gathering device 1.

[0051] First embodiment:

[0052] Combination Figures 2-6 As shown, the top side of the housing of the gas gathering device 1 is provided with an assembly slot 11. The shape of the assembly slot 11 is adapted to the bottom shape of the main unit 2, so that the bottom of the main unit 2 can be quickly assembled into the assembly slot 11 of the gas gathering device 1, thereby assembling the main unit 2 and the gas gathering device 1 into a whole.

[0053] As shown in the attached figure, in the embodiment, the assembly slot 11 is designed as a quadrilateral groove structure, and the assembly slot 11 is opened from the back plate 12 of the housing of the gas gathering device 1 towards the front; side support strips 13 are respectively provided above or below the side groove edges 113 on the left and right sides of the assembly slot 11, and the side support strips 13 are mainly used to provide rigid support for the main unit 2.

[0054] Limiting devices 23 are provided on both the left and right sides of the bottom of the main unit 2, a stop plate 24 is provided on the front side of the bottom of the main unit 2, and a locking plate 22 is provided on the rear side of the bottom of the main unit 2.

[0055] In this embodiment, the limiting device 23 is a limiting side plate that extends outward from the left and right sides of the main unit 2. Additionally, the stop plates 24 also extend outward from the front side of the main unit 2. The limiting device 23 and the stop plates 24 can be integrally formed with the outer shell of the main unit 2 or be assembled separately; this is not limited here.

[0056] When assembling the bottom of the main unit 2 with the assembly slot 11 of the gas-gathering device 1, the side groove edges 113 and side support bars 13 of the assembly slot 11 form a vertical and / or horizontal limiting structure for the limiting device 23 of the main unit 2. Specifically, the limiting devices 23 on the left and right sides of the main unit 2 are respectively supported on the corresponding side support bars 13 of the gas-gathering device 1. The side support bars 13 on the left and right sides provide support for the limiting devices 23 on the left and right sides of the main unit 2, and the side groove edges 113 on the left and right sides of the assembly slot 11 form a horizontal limiting abutment with the left and right sides of the bottom of the main unit 2. In addition, a C-shaped groove 15 is formed between each side support bar 13 and the corresponding side groove edge 113. The limiting devices 23 on the left and right sides of the main unit 2 are all located in the C-shaped groove 15. The C-shaped groove 15 forms a vertical limiting structure for the limiting devices 23, allowing the limiting devices 23 to adjust their position in the front and back directions within the C-shaped groove 15.

[0057] After the main unit 2 is assembled with the assembly slot 11 of the gas gathering device 1 at its bottom, the stop plate 24 of the main unit 2 extends below the front groove edge 114 of the assembly slot 11, forming a vertical stop engagement with the front groove edge 114. The front groove edge 114 abuts against the stop plate 24 to prevent it from moving forward, thus preventing the main unit 2 from coming off the assembly slot 11 of the gas gathering device 1. The locking plate 22 of the main unit 2 is located on the outer side of the back plate 12 of the gas gathering device 1. The back plate 12 prevents the locking plate 22 from moving towards the front groove edge 114, and a locking structure is provided between the locking plate 22 and the back plate 12. The locking structure locks the locking plate 22 and the back plate 12 together, so that the stop plate 24 maintains its stop engagement with the front groove edge 114 and does not move backward, thereby achieving a reliable connection and assembly between the main unit 2 and the assembly slot 11.

[0058] The locking structure can employ one of the existing methods, such as a screw-on structure, a snap-on structure, or a magnetic structure. For example, as shown in the attached diagram, the locking structure includes: a plurality of first locking holes 121 on the back plate 12, a plurality of second locking holes 221 on the locking plate 22, and a locking fastener 3 that securely connects the first locking holes 121 to the second locking holes 221. The locking fastener 3 is typically made of screws, resulting in low cost and simple operation.

[0059] In addition, a front support strip 14 is provided inside the assembly slot 11, located below the front slot edge 114. A limiting groove 16 is formed between the front support strip 14 and the front slot edge 114, and a stop plate 24 is inserted into the limiting groove 16. While the limiting groove 16 forms a stop fit with the stop plate 24, the front support strip 14 also provides support for the stop plate 24, which helps to improve the firmness of the assembly structure between the main unit 2 and the gas gathering device 1.

[0060] The specific operation for assembling the bottom of the main unit 2 with the assembly slot 11 of the gas gathering device 1 is as follows: Insert the stop plate 24 of the main unit 2 into the assembly slot 11 from the back plate 12 of the gas gathering device 1, so that the limiting devices 23 on the left and right sides of the main unit 2 are respectively inserted into the C-shaped grooves 15 formed by the side groove edges 113 and the side support bars 13 on the left and right sides of the assembly slot 11. Use the C-shaped grooves 15 to guide the side groove edges 113, and push the main unit 2 to move forward in the assembly slot 11 until the stop plate 24 on the front side of the main unit 2 is inserted below the front groove edge 114 to form a stop fit. At this time, the locking plate 22 on the rear side of the main unit 2 is attached to the outer side of the back plate 12. Use screws or other locking fasteners 3 to pass through the first locking hole 121 and the second locking hole 221 to lock the locking plate 22 to the back plate 12. The assembly operation is very simple.

[0061] Second embodiment:

[0062] Further integration Figures 7-10 As shown, compared with the first embodiment, in the second embodiment, the limiting device 23 extends downward relative to the left and right sides of the host 2, and the limiting device 23 and the shell of the host 2 are integrally formed or separately assembled.

[0063] Similar to the first embodiment, the top side of the housing of the gas gathering device 1 is provided with an assembly slot 11, and side support strips 13 are respectively provided below the side groove edges 113 on the left and right sides of the assembly slot 11. The side support strips 13 and the side groove edges 113 can be integrally formed or separately assembled.

[0064] In this embodiment, the side groove edge 113 and the side support bar 13 form a left-right limiting structure for the limiting device 23 of the main unit 2. Specifically, the limiting devices 23 on the left and right sides of the main unit 2 abut against the side support bar 13, and the side support bar 13 provides support for the side support bar 13; since the side support bar 13 is located below the side groove edge 113, the side groove edge 113 can provide left-right limiting for the left and right sides of the main unit 2.

[0065] Furthermore, a positioning groove 19 is provided on the side support bar 13, and a downwardly extending positioning block 231 is provided on the limiting device 23. The positioning block 231 is inserted into the positioning groove 19, thereby allowing the side support bar 13 to limit the limiting device 23 in the left-right and front-back directions.

[0066] Furthermore, the stop plate 24 on the front side of the main unit 2 also extends outward relative to the front side of the main unit 2. The stop plate 24 can be integrally formed with the outer shell of the main unit 2 or be a separate assembly structure, which is not limited here. The stop plate 24 is inserted into the front groove edge 114 to form a stop fit, which restricts the main unit 2 from coming out of the assembly groove 11 in the vertical direction.

[0067] In some preferred embodiments, in order to further improve the firmness of the stop fit structure between the stop plate 24 and the front groove edge 114, a retaining plate 17 is provided below the front groove edge 114, and a hook is provided at the end of the stop plate 24, which is fastened and connected to the retaining plate 17 through the hook.

[0068] To facilitate the assembly of the bottom of the main unit 2 with the assembly slot 11 of the gas-gathering device 1, a clearance notch 18 is provided between the side support strip 13 and the fastening plate 17. The clearance notch 18 is of sufficient size to allow one end of the limiting device 23 to extend into the clearance notch 18, thereby engaging the hook at the end of the stop plate 24 with the lower end of the fastening plate 17. Figure 8B As shown.

[0069] Furthermore, a forward-sloping guide plate 25 is provided on the rear side of the bottom of the main unit 2. When the main unit 2 is assembled into the assembly slot 11 of the gas gathering device 1, the guide plate 25 and the top surface of the back plate 12 of the gas gathering device 1 form a sloping guide, which helps the rear part of the bottom of the main unit 2 to be inserted into the assembly slot 11 more quickly and accurately under the action of the sloping guide.

[0070] The specific operation of assembling the bottom of the main unit 2 with the assembly slot 11 of the gas gathering device 1 in the second embodiment is as follows: Figure 8A As shown, the stop plate 24 of the main unit 2 is inserted forward from the back plate 12 of the gas-gathering device 1 into the assembly slot 11, so that the limiting devices on the left and right sides of the main unit 2 are respectively located above the side groove edges 113 on the left and right sides of the assembly slot 11; further tilt the front side of the main unit 2 slightly forward so that the stop plate 24 is inserted below the front groove edge 114. At this time, the front part of the limiting device 23 passes through the clearance notch 18, and the hook at the end of the stop plate 24 is fastened and connected to the lower end of the fastening plate 17, as shown. Figure 8B As shown; finally, place the main unit 2 flat in the assembly slot 11, align the positioning block 231 of the limiting device 23 and insert it into the positioning slot 19, and guide the rear part of the main unit 2 smoothly into the assembly slot 11 by the inclined surface formed between the guide plate 25 and the top surface of the back plate 12 of the gas gathering device 1. Finally, use screws or other locking fasteners 3 to pass through the first locking hole 121 and the second locking hole 221 to lock the locking plate 22 and the back plate 12, resulting in the following: Figure 9 The assembly state is shown. Therefore, the entire assembly process is very simple and easy to operate.

[0071] Third embodiment:

[0072] A first electrical connection device is provided inside the gas-gathering device 1, and a second electrical connection device is provided at the bottom of the main unit 2. During the installation process of the gas-gathering device 1 and the main unit 2, the first electrical connection device and the second electrical connection device can be connected manually or automatically.

[0073] For example, the main unit 2 is connected to an external power source via a power plug. A control circuit board is installed inside the main unit 2. The power cord and the control line connected to the control circuit board are both connected to the second electrical connection device. The electrical components inside the gas gathering device 1 are all connected to the first electrical connection device. The first electrical connection device and the second electrical connection device are docked to complete the electrical coupling connection, so that the main unit 2 can control the gas gathering device 1 to work.

[0074] like Figure 11 As shown, based on the first embodiment of the gas extraction and exhaust equipment, a first electrical connection device 4 is provided inside the gas gathering device 1; a second electrical connection device 5 is connected to the bottom of the main unit 2 via a flexible wire 6. The flexible wire 6 is designed with sufficient margin to allow the second electrical connection device 5 of the main unit 2 to be manually plugged into the first electrical connection device 4 inside the gas gathering device 1 during the assembly process of the main unit 2 and the gas gathering device 1.

[0075] Of course, the first electrical connection device 4 and the second electrical connection device 5 can also be designed as magnetic structures. During the assembly of the host 2 and the gas gathering device 1, the first electrical connection device 4 and the second electrical connection device 5 are automatically magnetically attracted and coupled together under the mutual magnetic attraction.

[0076] Of course, the first electrical connection device 4 and the second electrical connection device 5 may not adopt an automatic magnetic attraction structure, but rather a plug-in structure, so that the first electrical connection device 4 and the second electrical connection device 5 can be automatically connected during the assembly process of the main unit 2 and the gas gathering device 1.

[0077] For example, in the first embodiment, the first electrical connection device 4 is positioned below the front groove edge 114 of the gas gathering device 1 and faces rearward, while the second electrical connection device 5 is positioned on the front side of the bottom of the main unit 2 and faces forward. The limiting devices 23 on the left and right sides of the bottom of the main unit 2 are respectively inserted into the C-shaped grooves 15 formed by the side groove edges 113 and the side support bars 13 on the left and right sides of the assembly slot 11 and move forward. When the stop plate 24 on the front side of the main unit 2 is inserted below the front groove edge 114 to form a stop fit, the second electrical connection device 5 and the first electrical connection device 4 complete an accurate docking connection.

[0078] For example, in the second embodiment, the first electrical connection device 4 is positioned upwards near the back plate 12 on the gas-gathering device 1, and the second electrical connection device 5 is positioned downwards at the corresponding position on the bottom of the main unit 2. During the assembly process of the bottom of the main unit 2 into the assembly slot 11 of the gas-gathering device 1, when the rear part of the bottom of the main unit 2 is guided downwards and slids into the assembly slot 11 by the guide plate 25, the first electrical connection device 4 will align with the second electrical connection device 5, and as the bottom of the main unit 2 is assembled in place within the assembly slot 11, the first electrical connection device 4 and the second electrical connection device 5 will also complete the docking connection.

[0079] Combination Figures 12-14 As shown. The first electrical connection device 4 includes a plug 42, a sealing device 43 (usually a sealing ring) sleeved on the outer side of the plug 42, and a first electrical connector 44 located at the end of the plug 42. The first electrical connection device 4 is directly fixed to the gas-gathering device 1 via the plug 42, or the plug 42 is fixed to the first mounting base plate 41, and is fixed to the gas-gathering device 1 via the first mounting base plate 41.

[0080] The second electrical connection device 5 includes a second mounting base plate 51, a plug seat 52 that is floatingly connected to the second mounting base plate 51 and has a receiving cavity, a floating seat 54 that is limited in the receiving cavity by an elastic floating structure, and a second electrical connector 55 that is disposed in the receiving cavity and fixed to the end of the floating seat 54.

[0081] The first electrical connection device 4 and the second electrical connection device 5 are connected to each other. The plug 42 is inserted into the receiving cavity of the plug socket 52. The sealing device 43 forms a seal between the plug 42 and the plug socket 52. The elastic floating structure generates a floating force on the floating seat 54 in the direction of the first electrical connection device 4, so that the first electrical connector 44 and the second electrical connector 55 maintain a reliable electrical coupling connection.

[0082] For example, the first electrical connector 44 includes a plurality of conductive pins, while the second electrical connector 55 correspondingly includes a plurality of conductive holes. When the first electrical connector 44 and the second electrical connector 55 form an electrical coupling connection, each conductive pin is inserted into a corresponding conductive hole.

[0083] The elastic floating structure is located at the bottom of the receiving cavity of the plug-in seat 52. The elastic floating structure includes a limiting post 58 (e.g., a limiting screw structure) that limits the floating seat 54 in the receiving cavity and a compression spring 53 sleeved on the limiting post 58 and located below the floating seat 54. The compression spring 53 generates an upward elastic force on the floating seat 54.

[0084] The connector 52 has a fixing part 521, and a mounting hole 522 is provided in the fixing part 521. The fixing member 59 passes through the mounting hole 522 and limits the connector 52 to the second mounting base plate 51. The diameter of the mounting hole 522 is larger than the outer diameter of the part of the fixing member 59 located inside the mounting hole 522. A movable gap is formed between the hole wall of the mounting hole 522 and the fixing member 59. This movable gap is used to provide automatic position adjustment of the connector 52 relative to the second mounting base plate 51, so that the connector 52 can move relative to the second mounting base plate 51 within the movable gap according to the fixing member 59 to achieve a floating connection.

[0085] By setting this movable gap and utilizing the floating connection between the connector 42 and the second mounting plate 51 within the movable gap range, the misalignment gap between the connector 42 and the socket 52 can be quickly corrected, ensuring that the connector 42 can be quickly and accurately inserted into the socket 52.

[0086] 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.
