That is, unless specifically described, each feature is only an example in a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0045] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific implementation manners.

[0046] In this embodiment, a magnetic filter and a heating device including the magnetic filter are proposed. The magnetic filter is used for magnetically filtering magnetic impurities in the fluid flowing in the heating device, avoiding damage to other structures in the heating device. The structure of the magnetic filter is compact, with a high degree of integration and low cost. Among them, the magnetic filter can also be used in other devices that require magnetic filtering, not limited to being used in heating devices only.

[0047] Specifically, asFigures 1 to 4 As shown, the magnetic filter includes a filter assembly 1, a valve body assembly 2 and a sewage discharge assembly 3; wherein the filter assembly 1 includes an outer shell 11 and a magnetic filter element 12, a receiving chamber 14 is formed in the outer shell 11, and the magnetic filter element 12 is located in the receiving chamber 14; the valve body assembly 2 has at least a fluid inlet 211, a fluid outlet 212 and a connecting port 213, is coupled to the outer shell 11 through the connecting port 213, and can fill the receiving chamber 14 with fluid through the fluid inlet 211, so that the magnetic filter element 12 filters the magnetic impurities in the fluid, and discharges the filtered fluid to the outside through the fluid outlet 212; the sewage discharge assembly 3 is integratedly installed in the outer shell 11 and is located below the magnetic filter element 12, when the magnetic filter element 12 is pulled out of the receiving chamber 14, the sewage discharge assembly 3 is in an open state, so that the magnetic impurities are discharged to the outside of the outer shell 11 through the sewage discharge assembly 3.

[0048] A magnetic filter element 12 is arranged in the accommodating cavity 14 of the outer shell 11, and fluid is filled into the accommodating cavity 14 through the fluid inlet, so that the magnetic filter element 12 magnetically filters the magnetic impurities in the fluid; at the same time, the sewage discharge component 3 is integrated and installed on the outer shell 11 and is located below the magnetic filter element 12; when the magnetic filter element 12 is pulled out of the accommodating cavity 14, the sewage discharge component 3 is in an open state, so that the magnetic impurities are discharged to the outside of the outer shell 11 through the sewage discharge component 3.

[0049] Compared with the prior art, the magnetic filter in this embodiment changes the installation method of the sewage discharge component 3 on the outer shell 11; by integrating the sewage discharge component 3 into the outer shell 11, the sewage discharge component 3 and the filter component 1 form an integrated structure. Compared with the prior art in which the sewage discharge component 3 is installed on the outer shell 11 as a separate structural module, the structure of the entire magnetic filter can be compact and the integration level is high; and, since the integrated structure is adopted, the installation structure in the sewage discharge component 3 can be omitted, the sewage discharge component 3 includes fewer parts, thereby reducing the cost of the magnetic filter.

[0050] Furthermore, if Figures 1 to 3 As shown, the valve body assembly 2 includes a valve body 21 and a valve core 22. A connecting port 213 is provided on the valve body 21 so that the valve body 21 is sealedly connected to one side of the outer shell 11 through the connecting port 213. The valve core 22 extends from the fluid inlet 211 to the accommodating chamber 14, so that the valve core 22 is used to fill the accommodating chamber 14 with fluid so as to filter magnetic impurities in the fluid through the magnetic filter element 12.

[0051] By extending the length of the valve core 22 into the accommodation cavity 14, the side of the valve core 22 close to the magnet filter 12 is made closer, thereby reducing the distance between the valve core 22 and the magnet filter 12. On the one hand, it can prevent the fluid in the valve core 22 from flowing out through the gap between the valve core 22 and the valve body 21 before reaching the magnet filter 12, ensuring that most of the fluid in the valve core 22 can flow to the magnet filter 12 for filtration, thus ensuring a better filtration effect of the magnetic filter on the fluid. On the other hand, since most of the fluid in the valve core 22 will flow to the magnet filter 12, the flow rate of the fluid flowing to the magnet filter 12 is relatively large, which can increase the pressure of the fluid, ensuring that the filtered fluid can still flow out through the gap between the valve core 22 and the valve body 21 with a relatively large pressure.

[0052] It should be noted that here, there is no limitation on the specific extended length of the valve core 22, as long as the length of the valve core 22 can be extended so that the valve core 22 can be located in the accommodation cavity 14, and the specific position of the valve core 22 in the accommodation cavity 14 is not limited.

[0053] Furthermore, as Figures 1 to 5 shown, a water inlet joint 23 is connected to one end of the valve core 22 where the fluid inlet 211 is located. The fluid in the water inlet joint 23 is filled into the accommodation cavity 14 through the valve core 22, and the filtered fluid in the accommodation cavity 14 flows out to the fluid outlet 212 successively through the gap between the valve core 22 and the outer housing 11 and the gap between the valve core 22 and the valve body 21, so that the fluid flows out of the magnetic filter through the fluid outlet 212. Among them, the water inlet joint 23 is located in the valve body 21, and a second sealing ring 47 is connected between the water inlet joint 23 and the valve body 21.

[0054] Specifically, as Figures 1 to 4 shown, the outer housing 11 includes a main body 111 and a base 112; among them, the valve body 21 is sealingly connected to one side of the main body 111; the base 112 is sealingly connected to the lower part of the main body 111 to form an accommodation cavity 14 in the main body 111 and the base 112, and the sewage discharge assembly 3 is integrally installed on the base 112. Among them, a first sealing ring 46 is connected between the base 112 and the main body 111.

[0055] Furthermore, as Figures 1 to 3As shown, the main body 111 includes a connected main body portion 1111 and a connecting portion 1112. The accommodation cavity 14 is arranged inside the main body portion 1111. The connecting portion 1112 is used for sealing connection with the connection port 213 of the valve body 21. The main body portion 1111 is connected to the base 112. The valve core 22 passes through the connecting portion 1112 and extends into the main body portion 1111, making the length of the valve core 22 longer to prevent the valve core 22 from passing through the valve body 21 and being located within the connecting portion 1112. Among them, the filtered fluid in the accommodation cavity 14 flows through the gap between the valve core 22 and the connecting portion 1112 and then to the gap between the valve core 22 and the valve body 21 in sequence. In this embodiment, the main body portion 1111 and the connecting portion 1112 are of an integrally formed structure.

[0056] Specifically, a snap ring is connected between the connecting portion 1112 and the connection port 213 of the valve body 21 to enable snap connection between the connecting portion 1112 and the valve body 21. And a first sealing gasket is connected between the connecting portion 1112 and the valve body 21, and the valve body 21 and the connecting portion 1112 are connected through a connection cap 24. Among them, the snap ring and the first sealing gasket are respectively located inside the connection cap 24.

[0057] Specifically, as Figure 3 and Figure 4 、 Figure 6 and Figure 7 shown, the sewage discharge assembly 3 includes a valve rod 31 and a hollow sealing ball 32. Among them, the hollow sealing ball 32 is sealed and rotatably arranged inside the base 112. The valve rod 31 is inserted along one side of the base 112 and connected to the hollow sealing ball 32. Rotating the valve rod 31 can drive the hollow sealing ball 32 to rotate to connect or disconnect the hollow sealing ball 32 from the accommodation cavity 14, so that the sewage discharge assembly 3 is in an open state or a closed state. Among them, two third sealing rings 48 are connected between the valve rod 31 and the base 112 at intervals.

[0058] When filtering the fluid, rotate the valve rod 31 to drive the hollow sealing ball 32 to rotate, so that the hollow sealing ball 32 rotates to be disconnected from the accommodation cavity 14, and the filtered fluid in the accommodation cavity 14 flows out to the fluid outlet 212 through the gap between the valve core 22 and the connecting portion 1112 and the gap between the valve core 22 and the valve body 21 in sequence. When the filtering is over, rotate the valve rod 31 again to drive the hollow sealing ball 32 to rotate, so that the hollow sealing ball 32 rotates to be connected to the accommodation cavity 14. At this time, the magnetic impurities filtered in the accommodation cavity 14 can fall outside the outer housing 11 through the hollow sealing ball 32.

[0059] Specifically, as Figure 6 and Figure 7As shown, the sewage discharge assembly 3 further includes a handle 33. The handle 33 is connected to the part of the valve stem 31 located outside the base 112, so that the valve stem 31 can be driven to rotate synchronously by rotating the handle 33, making the rotation operation of the valve stem 31 simple, convenient, time-saving and labor-saving.

[0060] Further, as Figure 6 and Figure 7 shown, the sewage discharge assembly 3 further includes a mounting seat 34 and a sewage discharge interface 35; wherein, the mounting seat 34 is sealingly and detachably connected to the bottom end of the base 112. A second sealing gasket 42 is connected between the mounting seat 34 and the base 112, and the mounting seat 34 is threadedly connected to the bottom end of the base 112; the hollow sealing ball 32 is sealingly arranged on the mounting seat 34. A third sealing gasket 43 is connected between the hollow sealing ball 32 and the mounting seat 34, and a fourth sealing gasket 44 is connected between the hollow sealing ball 32 and the base 112, so that the third sealing gasket 43 and the fourth sealing gasket 44 can seal the hollow sealing ball 32; the sewage discharge interface 35 is sealingly and detachably connected to the mounting seat 34, and the hollow sealing ball 32 rotates to connect or disconnect the accommodating cavity 14 and the sewage discharge interface 35, so that the sewage discharge assembly 3 is in an open state or a closed state; and, a fifth sealing gasket 45 is connected between the sewage discharge interface 35 and the mounting seat 34, and the sewage discharge interface 35 is threadedly connected to the bottom end of the mounting seat 34.

[0061] Specifically, by rotating the hollow sealing ball 32 to connect the accommodating cavity 14 and the sewage discharge interface 35, the magnetic impurities filtered in the accommodating cavity 14 can sequentially pass through the hollow sealing ball 32 and the sewage discharge interface 35 and fall outside the outer housing 11, realizing the discharge of the magnetic impurities.

[0062] It should be noted that since the above-mentioned mounting seat 34 and the base 112 are detachably connected, and the mounting seat 34 and the sewage discharge interface 35 are also detachably connected, and the handle 33 can be directly detached from the valve stem 31, so as to facilitate the removal of the valve stem 31 from the base 112, that is, the entire sewage discharge assembly 3 is detachably arranged relative to the base 112, so that the sewage discharge assembly 3 can be disassembled and assembled according to actual use requirements, making the disassembly, assembly and use of the sewage discharge assembly 3 more flexible and convenient.

[0063] Further, as Figures 1 to 4As shown in the figure, the magnet filter element 12 includes a limit sleeve 122, a base 121, and a plurality of magnets 123. Among them, the limit sleeve 122 is non-magnetic. One end of the limit sleeve 122 is disposed in the accommodation cavity 14, and the other end of the limit sleeve 122 extends upward along the Z-axis out of the main body 111. The plurality of magnets 123 are stacked in the limit sleeve 122 along the Z-axis so that the magnets 123 magnetically adsorb magnetic impurities to the outer peripheral surface of the limit sleeve 122. One end of the base 121 extends outside the main body 111, and the other end of the base 121 passes through the limit sleeve 122 and is connected to each magnet 123. Moreover, the base 121 can drive each magnet 123 to be pulled out of the main body 111 upward along the Z-axis relative to the limit sleeve 122 to release the magnetic adsorption of the magnets 123 on the magnetic impurities. At this time, the sewage discharge assembly 3 is in an open state, that is, the hollow sealing ball 32 communicates the accommodation cavity 14 and the sewage discharge interface 35. Thus, each magnetic impurity magnetically adsorbed on the outer peripheral surface of the limit sleeve 122 automatically falls downward under its own gravity to the hollow sealing ball 32 and the sewage discharge interface 35 in the sewage discharge assembly 3, so that the magnetic impurities are discharged out of the magnetic filter through the sewage discharge interface 35. In this embodiment, as Figure 2 shown, three magnets 123 are stacked in the limit sleeve 122, and a magnetic conduction block 125 is provided between the base 121 and the topmost magnet 123, and the base 121, the magnetic conduction block 125, and the three magnets 123 are connected by screws 124.

[0064] Furthermore, as Figure 2 and Figure 4 shown, the filter assembly 1 further includes a mesh filter element 13. The mesh filter element 13 is located in the accommodation cavity 14 and is disposed around the outer periphery of the magnetic sleeve of the magnet filter element 12. The mesh filter element 13 is used to filter the flocculent impurities in the fluid, so that the filtering effect on the fluid in the accommodation cavity 14 is better. Among them, the mesh filter element 13 is specifically a buffer mesh.

[0065] It should be noted that by providing the mesh filter element 13 in the accommodation cavity 14, when the fluid passes through the mesh filter element 13, the flow pressure and flow rate of the fluid are buffered. That is, the flow rate of the fluid in the accommodation cavity 14 can be made slower, so that the flow time of the fluid in the accommodation cavity 14 is longer, which is conducive to filtering out more impurities through the mesh filter element 13 or the magnet filter element 12, and further ensuring a better filtering effect of the mesh filter element 13 and the magnet filter element 12 on the fluid.

[0066] The specific working process of the magnetic filter in this embodiment is as follows. The initial state of the sewage discharge assembly 3 is a closed state, and at this time, the magnet filter element 12 is located in the accommodation cavity 14:

[0067] First, the fluid in the water inlet joint 23 is filled into the accommodation cavity 14 through the valve core 22. After the fluid in the accommodation cavity 14 is magnetically adsorbed by the magnet 123, the magnetic impurities in the fluid are adsorbed onto the outer peripheral surface of the limit sleeve 122. And the fluid in the accommodation cavity 14 passes through the mesh filter element 13 to enable the mesh filter element 13 to filter the floccular impurities in the fluid.

[0068] After that, the filtered fluid in the accommodation cavity 14 sequentially flows through the gap between the valve core 22 and the connecting portion 1112, and the gap between the valve core 22 and the valve body 21 to the fluid outlet 212 of the valve body 21, and flows out of the magnetic filter through the fluid outlet 212 of the valve body 21, so as to realize the filtration of the fluid.

[0069] After the filtration is completed, the handle 33 is rotated again to drive the valve stem 31 and the hollow sealing ball 32 to rotate, so that the hollow sealing ball 32 connects the accommodation cavity 14 and the sewage interface 35, so that the sewage component 3 is in an open state. At the same time, the base 121 is pulled out upward along the Z axis to drive each magnet 123 to be pulled out upward along the Z axis relative to the limit sleeve 122 to the outside of the main body 111, so as to release the magnetic adsorption of the magnet 123 on the magnetic impurities, so that each magnetic impurity magnetically adsorbed on the outer peripheral surface of the limit sleeve 122 automatically falls downward from the accommodation cavity 14 under its own gravity to the hollow sealing ball 32 and the sewage interface 35, so that the magnetic impurities can be discharged out of the magnetic filter through the sewage interface 35, so as to realize the automatic discharge of the magnetic impurities.

[0070] In the magnetic filter of this embodiment, by forming an integrated structure of the sewage component 3 and the filter component 1, the structure of the entire magnetic filter can be made compact and the integration degree is relatively high. Moreover, the integrated manner of the integrated structure can reduce the cost of the magnetic filter.

[0071] And, in the magnetic filter of this embodiment, by extending the length of the valve core 22 into the accommodation cavity 14, it can be ensured that most of the fluid in the valve core 22 can flow to the magnet filter element 12 for filtration, so as to ensure that the magnetic filter has a good filtration effect on the fluid. At the same time, it can ensure that the pressure of the fluid in the accommodation cavity 14 is relatively large, and further ensure that the filtered fluid can still flow out through the gap between the valve core 22 and the valve body 21 with a relatively large pressure.

[0072] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
