DETAILED DESCRIPTION

[0028] The utility model will be further explained in detail below in combination with the drawings.

[0029] The specific embodiment is only the explanation of the utility model, and it is not the limitation of the utility model, and the person skilled in the art can make the modification without the creative contribution according to the need after reading the present specification, but as long as in the right claim range of the utility model, it is protected by the patent law.

[0030] The embodiment relates to a connecting structure of a filter device, referring to Figures 1-4 , comprising: a main shell body 100, an interface part 200, a switch part 300 and a mounting part 400.

[0031] The main shell body 100 is the basic structure of the whole filter device, which is used to accommodate the filter 110. It provides a closed space for the filtration process, ensuring that the water flow can effectively remove impurities when passing through the filter 110. The interface part 200 is located at one end of the main shell body 100, which is provided with a water inlet 210 and a water outlet 220, used to connect the water source and the target output point, so that untreated water can enter the filter device through the water inlet 210, and clean water flows out from the water outlet 220 after filtration. The switch part 300 is located at the other end of the main shell body 100, which is mainly used to control the connection state of the filter device. Therefore, when the switch part 300 is actuated in a direction, it drives the mounting part 400 to rotate and fit into the mounting hole on the refrigerator, and the water inlet 210 and the water outlet 220 are connected to the refrigerator pipeline, and the water flow is filtered by the filter 110 to remove impurities. The user only needs to actuate the switch part 300 to complete the entire installation process without using additional tools or performing complex screwing operations, simplifying the installation steps. Through simple operation, the mounting part 400 can quickly and accurately screw into the mounting hole on the refrigerator, reducing the installation time. After the water inlet 210 and the water outlet 220 are correctly connected to the pipeline of the refrigerator, the water flow can smoothly pass through the filter device. The water inlet 210 introduces unfiltered raw water, which is purified by the filter 110 and flows out from the water outlet 220 as clean water. The filter 110 can effectively remove impurities, suspended solids and other pollutants in the water, providing clean and safe drinking water. Therefore, the filter device not only effectively purifies the water, but also greatly simplifies the installation steps of the user, improving the use convenience. The user only needs to actuate the switch part by a certain external force, without the help of additional tools, to complete the installation and removal of the filter, and thus there is no problem of water leakage caused by loose connection, which has the advantages of simple connection operation and quick assembly.

[0032] In this embodiment, reference is made to Figures 3-5The switch part comprises a shell, a fixed shaft, a shaft sleeve, a lever switch, a first gear and a second gear. The shell 310 is used to accommodate the internal mechanical components, ensuring that the components are not affected or damaged by the external environment during normal operation. The fixed shaft 320 serves as a support point, allowing the shaft sleeve 330 and the lever switch 340 to rotate around it. Specifically, the connection between the fixed shaft 320 and the shell 310 is provided with several convex points 321, which can increase the connection strength between the two to prevent the shaft sleeve 330 and the lever switch 340 from loosening or rotating during rotation. The shaft sleeve 330 is rotatably assembled on the fixed shaft 320, and the lever switch 340 is arranged on the shaft sleeve 330. Specifically, the shaft sleeve 330 and the lever switch 340 are integrally formed. Therefore, when the user pulls the lever switch 340, the manual pulling force is directly transmitted to the shaft sleeve 330, causing the shaft sleeve 330 to rotate around the fixed shaft 320, thereby driving the mounting part 400 to rotate and changing the connection state of the filter device. The first gear 350 is fixedly sleeved and assembled with the shaft sleeve 330, so when the lever switch 340 is pulled, the first gear 350 will also rotate. The switch part 300 is also provided with a bearing 380 fixedly connected with the first gear 350. The second gear 360 is fixedly assembled with the mounting part 400 and is engaged with the first gear 350. When the first gear 350 rotates due to the pulling of the lever switch 340, it will drive the second gear 360 to rotate. Since the second gear 360 is connected to the mounting part 400, it will in turn drive the mounting part 400 to rotate. The mounting part 400 penetrates the entire main shell body 100 and is connected to the second gear 360 at one end and protrudes from the interface part 200 at the other end. When the lever switch 340 is pulled and acts on the mounting part 400 through gear transmission, it can make the mounting part 400 rotate and insert into the mounting hole reserved in the refrigerator, thereby realizing the quick installation or disassembly of the filter device on the refrigerator. The user does not need to use the screwing method, thereby avoiding the situation that the screwing is not in place, causing connection failure and water leakage, which reflects the simplicity of the connection method.

[0033] In the present embodiment, reference is made to Figure 2, the first gear 350 is arranged perpendicularly to the second gear 360, so that the rotation axes are perpendicular to each other. When the lever switch 340 is actuated, the first gear 350 is driven to rotate in the horizontal direction, and the first gear 350 in turn drives the second gear 360 to rotate in the vertical direction through the meshing relationship. The force in the horizontal direction is converted into the force in the vertical direction, so that the user can control the mounting portion 400 to be screwed into or out of the mounting hole of the refrigerator by simply actuating the switch piece left or right or up and down. At the same time, by arranging the gears vertically, the various components can be effectively arranged in a limited space, so that the entire device is more compact and is convenient for integration into the refrigerator or other devices. In other embodiments, a locking mechanism can be provided at a specific position, and the switch piece can be pushed back to the original position only when the mounting portion 400 is completely screwed into place, thereby preventing accidental loosening.

[0034] In the present embodiment, with reference to Figures 4-5 , the inner circumferential side of the first gear 350 is provided with a first protruding portion 351, and the shaft sleeve 330 is provided with an insertion groove 331 for inserting the first protruding portion 351. By inserting the first protruding portion 351 into the insertion groove 331, when the shaft sleeve 330 rotates, the first gear 350 can rotate synchronously with the shaft sleeve 330. It is ensured that the user's operation of the lever switch 340 can be directly and accurately transmitted to the first gear 350, thereby further driving the second gear 360 and the mounting portion 400 to perform corresponding actions.

[0035] In the present embodiment, the housing 310 is provided with a stroke groove 370 for the lever switch 340 to be actuated back and forth. The stroke groove 370 provides a clear movement path and limit for the lever switch 340, and can accurately control the position change of the lever switch 340, thereby accurately adjusting the installation or disassembly action of the filter device.

[0036] In the present embodiment, with reference to Figures 2-4 , the side of the lever switch 340 is provided with a second protruding portion 341, and the stroke groove 370 is provided with a clamping portion 371 on the side facing the lever switch 340, which abuts against the second protruding portion 341. When the lever switch 340 moves to a specific position, the second protruding portion 341 will contact and lock with the clamping portion 371, thereby ensuring that the lever cannot easily move out of the set position. Specifically, when the second protruding portion 341 contacts the clamping portion 371, the user can feel a clear resistance or "click" sound through the sense of touch, which provides a feedback signal for the user to operate in place. This feedback signal helps to confirm that the lever switch 340 has been correctly moved to the predetermined position, at which the mounting portion is clamped on the mounting hole of the refrigerator, avoiding the problem of water leakage. At the same time, the clamping portion 371 can effectively prevent the lever switch 340 from accidentally sliding due to vibration, accidental touch, etc., thereby causing connection failure and leading to the problem of water leakage.

[0037] In the embodiment, referring to Figure 4 , the side of the abutting portion 371 abutting against the second protruding portion 341 is provided as an abutting surface 3711, and the side of the abutting portion 371 away from the abutting surface 3711 is provided with a guide inclined surface 3712. The abutting surface 3711 ensures that the second protruding portion 341 can firmly contact the abutting surface 3711 when the lever switch 340 moves to a specific position, further preventing the lever switch 340 from accidentally sliding due to external force or vibration. The guide inclined surface 3712 can guide the second protruding portion 341 to smoothly enter the abutting position, reducing the resistance feeling during operation. At the same time, it can also avoid the second protruding portion 341 directly impacting the abutting portion 371, thereby reducing the wear between the two. In other embodiments, a layer of lubricant can be applied to the surface of the guide inclined surface 3712, reducing friction and further reducing wear between the two.

[0038] In the embodiment, the bottom of the stroke groove 370 is also provided with a recessed portion 372 for facilitating the operation of the lever switch 340, which provides additional space for the user's fingers, making it easier for the user to grasp and operate the lever switch 340.

[0039] In particular, in the embodiment, referring to Figure 5 , the upper and lower sides of the lever switch 340 are provided with a first recessed surface 342 and a second recessed surface 343, which provide better gripping points or force points for the user's fingers, making it more labor-saving and comfortable to operate the lever switch 340. More specifically, the first recessed surface 342 is provided with a locked state mark (not shown), and the second recessed surface 343 is provided with an unlocked state mark (not shown). In other embodiments, the first recessed surface 342 can also be in the unlocked state, and the second recessed surface 343 can be in the locked state, which is not limited here.

[0040] In the embodiment, referring to Figure 6 , the mounting portion 400 includes a connecting rod 410 passing through the second gear 360 and a mounting head 420 fixedly assembled to the end of the connecting rod 410 away from the second gear 360. Specifically, a plurality of protruding points (not shown) are provided at the connection between the connecting rod 410 and the mounting head 420 to enhance the connection strength between the two. The connecting rod 410 passes through and is fixedly connected to the second gear 360. When the second gear 360 rotates, it drives the connecting rod 410 to rotate together. The connecting rod 410, as a key component for transmitting torque, ensures that the movement between the switch and the mounting head 420 can be smoothly performed. The mounting head 420 is provided in a shape (such as threads, buckles, etc.) that can be inserted into the reserved hole of the refrigerator. Through the rotation of the connecting rod 410, the mounting head 420 can be screwed into or out of the mounting hole on the refrigerator, achieving quick installation or disassembly of the filtering device.

[0041] In the embodiment, referring to Figure 6The mounting head 420 is provided with a boss 421 outwardly protruding at the connection with the interface part 200, and the interface part 200 is provided with a convex strip 230 in an arc shape matched with the boss 421. When the lever switch 340 is actuated in one direction, the boss 421 is driven to abut one end of the convex strip 230; when the lever switch 340 is actuated in the other direction, the boss 421 is driven to abut the other end of the convex strip 230. Through the cooperation of the boss 421 and the convex strip 230, when the lever switch 340 is actuated in different directions, the boss 421 will slide and finally stop at the two ends of the convex strip 230, thereby ensuring that the mounting head 420 can only rotate within a specific angle range, and the mounting head 420 can be accurately controlled to not exceed the predetermined position when being screwed into the mounting hole. In this way, the problem of poor sealing caused by screwing in too deep or insufficient can be avoided, and the problem of water leakage can be prevented.

[0042] The above is only used to illustrate the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skilled in the art should be covered in the scope of the claims of the utility model, as long as they do not deviate from the spirit and scope of the technical scheme of the utility model.
