[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does 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 construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] As Figures 1-3 shown, it is a preferred embodiment of the quick-release joint of the present invention. This quick-release joint is suitable for the rapid installation of the radiator fins of the electric heating oil radiator. The structure of this quick-release joint is simple, the connection is firm, the operation is convenient, and the fastening connection can be quickly realized.

[0053] This quick-release joint includes: a connecting member 1 and two fastening rings 2. Among them, the connecting member 1 is a columnar structure with openings at both ends. In this embodiment, the inner diameter of the middle section of the connecting member 1 is smaller than the inner diameters of the openings at both ends. The two fastening rings 2 are respectively connected to the two ends of the connecting member 1 through an elastic rotation fastening mechanism. Specifically, through the elastic rotation fastening mechanism, the inner wall of the fastening ring 2 is connected to the outer wall of the openings at both ends of the connecting member 1.

[0054] Furthermore, as Figure 4 、 5As shown in the figure, the elastic rotational fastening mechanism includes a number of first elastic bevel terminals 101 and second elastic bevel terminals 201 that are inserted and matched with each other. A number of first elastic bevel terminals 101 are evenly and spacedly arranged on the outer wall of the two open ends of the connecting member 1 along the circumferential direction. A number of second elastic bevel terminals 201 are evenly and spacedly arranged on the inner wall of the fastening ring 2 along the circumferential direction. The second elastic bevel terminal 201 can apply a radially inward fastening force to the first elastic bevel terminal 101, so that the inner diameter of the two open ends of the connecting member 1 becomes smaller, thereby realizing the fastening connection between the connecting member and the fitting to be installed. In this embodiment, the number of both the first elastic bevel terminals 101 and the second elastic bevel terminals 201 is 36, and the fitting to be installed is the fixed heat sink oil package 4011 and the split heat sink oil package 501.

[0055] Further, the first elastic bevel terminal 101 extends outward from the outer wall of the two open ends of the connecting member 1 along the radial direction of the connecting member 1. The first elastic bevel terminal 101 includes a first long straight surface portion 1011, a first short straight surface portion 1012, and a first inclined surface portion 1013. The first long straight surface portion 1011 and the first short straight surface portion 1012 are arranged along the radial direction of the connecting member 1, and the outer ends of the first long straight surface portion 1011 and the first short straight surface portion 1012 are connected by the first inclined surface portion 1013. Since the structure of the top of the first elastic bevel terminal 101 (i.e., the end far from the outer wall of the end of the connecting member 1) is relatively small in size, in order to improve the structural strength and facilitate processing and forming, the first elastic bevel terminal 101 further includes a first flat surface portion 1014, and the outer end of the first long straight surface portion 1011 is connected to the first inclined surface portion 1013 through the first flat surface portion 1014.

[0056] Similarly, the second elastic bevel terminal 201 extends inward from the inner wall of the fastening ring 2 along the radial direction of the fastening ring 2. The second elastic bevel terminal 201 includes a second long straight surface portion 2011, a second short straight surface portion 2012, and a second inclined surface portion 2013. The second long straight surface portion 2011 and the second short straight surface portion 2012 are arranged along the radial direction of the fastening ring 2, and the outer ends of the second long straight surface portion 2011 and the second short straight surface portion 2012 are connected by the second inclined surface portion 2013. Similarly, since the structure of the top of the second elastic bevel terminal 201 (i.e., the end far from the outer wall of the end of the connecting member 1) is relatively small in size, in order to improve the structural strength and facilitate processing and forming, the second elastic bevel terminal 201 further includes a second flat surface portion 2014, and the outer end of the second long straight surface portion 2011 is connected to the second inclined surface portion 2013 through the second flat surface portion 2014.

[0057] The first inclined surface portion 1013 and the second inclined surface portion 2013 are in contact with each other and can move relative to each other along their interface. Specifically, when the fastening ring 2 is assembled onto the outer wall of the end portion of the connecting member 1, the first inclined surface portion 1013 and the second inclined surface portion 2013 are in contact. When the fastening ring 2 is rotated, the second inclined surface portion 2013 can move in a direction away from or towards the bottom of the first inclined surface portion 1013 (i.e., the end connected to the outer wall of the end portion of the connecting member 1). When the second inclined surface portion 2013 moves towards the bottom of the first inclined surface portion 1013, the inner diameter of the openings at both ends of the connecting member 1 becomes smaller and tightens inwardly, and the connecting member 1 is tightly connected to the fitting to be assembled. When the second inclined surface portion 2013 moves away from the bottom of the first inclined surface portion 1013, the inner diameter of the openings at both ends of the connecting member 1 returns to its original size, and the connecting member 1 is loosened from the fitting to be assembled.

[0058] Both the first elastic inclined platform terminal 101 and the second elastic inclined platform terminal 201 are made of elastic materials such as rubber. Extrusion deformation can occur between the two. When the first inclined surface portion 1013 and the second inclined surface portion 2013 are extruded against each other, a supporting force is generated. Through mechanical analysis, it can be known that when the component forces of gravity and the supporting force along the inclined surface are equal to the frictional force, the first inclined surface portion 1013 and the second inclined surface portion 2013 will exhibit a stable stationary phenomenon at this time, thus forming a self-locking, that is, it can ensure the tightly locked state of the connecting member 1 and the fitting to be assembled. In addition, for the convenience of rotational operation and to ensure structural strength, except for the first elastic inclined platform terminal 101, the other parts of the connecting member 1 are made of metal materials. Similarly, except for the second elastic inclined platform terminal 201, the other parts of the fastening ring 2 are made of metal materials.

[0059] Furthermore, the quick-change joint further includes two first sealing rings 3, which are respectively arranged on the inner walls of the connecting member 1 near its two ends of the openings, so as to ensure the structural sealing after the quick-change joint is connected to the fitting to be assembled and prevent leakage of liquids such as heat-conducting oil.

[0060] As Figure 6 shown, this embodiment also provides a heat sink assembly, which includes a fixed heat sink assembly 4 and at least one split heat sink 5. The split heat sink 5 is connected to the fixed heat sink assembly 4 and between adjacent split heat sinks 5 through the quick-change joint provided in this embodiment. Heat-conducting oil is provided in both the fixed heat sink assembly 4 and the split heat sink 5.

[0061] The number of the split heat sinks 5 in this heat sink assembly can be changed and set according to actual usage needs. When the area of the room to be heated is relatively large, the number of the split heat sinks 5 can be increased to increase the heat dissipation area and the volume of the heat-conducting oil. When the area of the room to be heated is relatively small, the number of the split heat sinks 5 can be reduced to decrease the heat dissipation area and the volume of the heat-conducting oil, so that the heat sink assembly can meet different usage needs of users. Moreover, the volume of each split heat sink 5 is small, which is convenient for storage when not in use.

[0062] Further, as Figure 7 、 8 shown, at the upper and lower fixed heat sink oil bags 4011 of the fixed heat sink 401 on at least one side outside of the fixed heat sink assembly 4, a detachable connection sealing assembly 6 is provided. One end of the connecting member 1 of the quick-release joint is detachably connected to the fixed heat sink oil bag 4011. In this embodiment, at the upper and lower fixed heat sink oil bags 4011 of the fixed heat sink 401 on both sides outside of the fixed heat sink assembly 4, a detachable connection sealing assembly 6 is provided, that is, the split heat sinks 5 can be connected to both sides of the fixed heat sink assembly 4. Of course, according to different needs, it can also be designed that at the upper and lower fixed heat sink oil bags 4011 of the fixed heat sink 401 on one side outside of the fixed heat sink assembly 4, a detachable connection sealing assembly 6 is provided, that is, the split heat sink 5 can be connected to this side of the fixed heat sink assembly 4.

[0063] Correspondingly, at the upper and lower split heat sink oil bags 501 on at least one side of the split heat sink 5, a detachable connection sealing assembly 6 is provided. The other end of the connecting member 1 is detachably connected to the split heat sink oil bag 501. In this embodiment, at the upper and lower split heat sink oil bags 501 on both sides of the split heat sink 5, a detachable connection sealing assembly 6 is provided, that is, the split heat sink 5 can be connected to the fixed heat sink assembly 4 on both sides. Of course, according to different needs, it can also be designed that at the upper and lower split heat sink oil bags 501 on one side outside of the split heat sink 5, a detachable connection sealing assembly 6 is provided, that is, the split heat sink 5 can be connected to the fixed heat sink assembly 4 on this side.

[0064] Further, the sealing assembly 6 includes a sealing cover 601 and a second sealing ring 602. A fixing ring 7 is fixedly connected to the openings of the fixed heat sink oil bag 4011 and the split heat sink oil bag 501. The installation part of the sealing cover 601 is detachably connected to the fixing ring 7, and the second sealing ring 602 is sleeved on the installation part to ensure the seal between the sealing cover 601 and the fixing ring 7 and prevent the leakage of heat-conducting oil. Specifically, the fixing ring 7 is fixed to the inner walls of the fixed heat sink oil bag 4011 and the split heat sink oil bag 501, and the installation part of the sealing cover 601 is detachably connected to the fixing ring 7 through a threaded structure. This connection method of the threaded structure is simple to operate and can achieve quick disassembly and assembly.

[0065] In this embodiment, the heat sink assembly includes two split heat sinks 5 to meet the heating requirements. Sealing assemblies 6 that are detachably connected are provided at the upper and lower split heat sink oil bags 501 on both sides of the split heat sinks 5, and the two split heat sinks 5 are connected through a quick-change joint.

[0066] This embodiment also provides a splittable electric oil radiator, including the heat sink assembly provided in this embodiment. When users need to use it in rooms of different areas, they can choose to increase or decrease the number of split heat sinks according to the size of the room area, so as to meet the heating needs of rooms of different areas, meet the personalized needs of users, and provide a good user experience. Of course, the splittable electric oil radiator in this embodiment also includes other components and structures that existing electric oil radiators all have. Since these components and structures are not involved in the present invention, they will not be elaborated here.

[0067] For this splittable electric oil radiator, when users need to use it in rooms of different areas, they can choose to increase or decrease the number of split heat sinks according to the size of the room area, so as to meet the heating needs of rooms of different areas, meet the personalized needs of users, and provide a good user experience.

[0068] This embodiment also provides an assembling method for the heat sink assembly in this embodiment, including:

[0069] Step (1), remove the sealing assembly 6 at the fixed heat sink oil bag 4011 and the split heat sink oil bag 501 to be connected;

[0070] In this embodiment, there are two split heat sinks 5 to be installed, and the two split heat sinks 5 can be installed on the same side or both sides of the fixed heat sink assembly 4. Specifically, in this embodiment, the two split heat sinks 5 are installed on the same side of the fixed heat sink assembly 4.

[0071] Remove the sealing components 6 at the upper and lower fixed radiator oil bags 4011 on one side of the fixed radiator assembly 4, remove the sealing components 6 at the upper and lower split radiator oil bags 501 on both sides of one of the split radiators 5, and remove the sealing components 6 at the upper and lower split radiator oil bags 501 on one side of the other split radiator 5 for subsequent installation.

[0072] Step (2): Set one end of the connecting piece 1 of the quick-release joint outside the fixed radiator oil bag 4011 and the other end outside the split radiator oil bag 501; or set both ends of the connecting piece 1 outside the split radiator oil bags 501 of the two split radiators 5 respectively;

[0073] In this embodiment, two split radiators 5 need to be installed, so four quick-release joints are required for installation. Taking the installation process of connecting the fixed radiator oil bag 4011 and the split radiator oil bag 501 with one of the quick-release joints as an example, set one end of the connecting piece 1 of the quick-release joint outside the fixed radiator oil bag 4011 and the other end outside the split radiator oil bag 501. Similarly, when connecting the two split radiators 5, both ends of the connecting piece 1 of the quick-release joint are respectively set outside the split radiator oil bags 501 of the two split radiators 5 for subsequent tight connection.

[0074] Step (3): Rotate the fastening rings 2 at both ends of the connecting piece 1 so that the second inclined surface part 2013 of the second elastic inclined platform terminal 201 moves towards the bottom of the first inclined surface part 1013 of the first elastic inclined platform terminal 101, and fasten and fix the connecting piece 1 with the fixed radiator oil bag 4011 and the split radiator oil bag 501, or fasten and fix the connecting piece 1 with the split radiator oil bags 501 of the two split radiators 5.

[0075] Taking the fastening process of connecting the fixed radiator oil bag 4011 and the split radiator oil bag 501 with one of the quick-release joints as an example, rotate the fastening rings 2 at both ends of the connecting piece 1 of the quick-release joint so that the second inclined surface part 2013 of the second elastic inclined platform terminal 201 moves towards the bottom of the first inclined surface part 1013 of the first elastic inclined platform terminal 101, and the inner diameter of the opening at the end of the connecting piece 1 becomes smaller, thereby fastening and fixing the connecting piece 1 with the fixed radiator oil bag 4011 and the split radiator oil bag 501.

[0076] Similarly, when fastening the two split radiators 5, rotate the fastening rings 2 at both ends of the connecting piece 1 of the quick-release joint to fasten and fix the connecting piece 1 of the quick-release joint with the split radiator oil bags 501 of the two split radiators 5.

[0077] This assembly method is simple, fast, easy to operate, has a wide range of applications, and can enable the electric oil radiator to meet different usage requirements.

[0078] In other embodiments, according to different usage requirements, the heat sink assembly may further include three, four, five or other numbers of split heat sinks 5.

[0079] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
