[0047] The fixing assembly 4 further comprises an operating mechanism 5 which overcomes the elastic force of the elastic member 42 and pushes the fixing plate 41 to move out of the mounting base 3.

[0048] In some embodiments, the structure and working principle of the filter core body 1 refer to the prior art.

[0049] Referring to Figs. 1 to 7 In some embodiments, the fixed object is the mounting position of the spray-melting filter core, which is usually a plate-shaped structure or a box-shaped structure. The target position where the spray-melting filter core assembly is mounted on the fixed object usually has a mounting groove, which has a fixing groove inside. The spray-melting filter core assembly is fixed in the mounting groove when the fixing plate 41 extends into the fixing groove. When the fixing plate 41 is disengaged from the fixing groove, the spray-melting filter core assembly is disengaged from the mounting groove, and at this time, the spray-melting filter core assembly can be conveniently taken out.

[0050] Referring to Figs. 1 to 7 In some embodiments, the mounting base 3 is provided with a cavity 31, and the fixing plate 41 is arranged in the cavity 31.

[0051] The cavity 31 is used to accommodate the fixing plate 41 and part of the operating mechanism 5. The cavity 31 provides space for the displacement of the fixing plate 41, so that the fixing plate 41 can protrude out of the side wall of the mounting base 3, or the fixing plate 41 can retreat back into the mounting base 3.

[0052] In some embodiments, the fixing plate 41 is provided with a protruding plate 43, one end of the elastic member 42 is fixed to the protruding plate 43, and the other end of the elastic member 42 is fixed to the side wall of the mounting base 3.

[0058] It can be understood that the driving portion 51 has the arc surface, the sliding portion 52 has the driving surface 521, and the driving surface 521 is arranged in an inclined manner. When the driving surface 521 is in contact with the arc surface, the arc surface divides the force applied by the driving surface 521 into two components, one of which overcomes the elastic force of the elastic member 42 to push the fixed plate 41 to displace.

[0059] Referring to Figs. 1 to 7 In some embodiments, the operating mechanism 5 further includes a rod member 53, the filter element body 1 is provided with a through hole matched with the rod member 53, the mounting seat 3 is provided with a matching hole matched with the rod member 53, the rod member 53 is fixedly connected with the sliding portion 52, the end cover 2 is provided with a threaded hole, the rod member 53 is provided with an external thread matched with the threaded hole, and an upper end of the rod member 53 extends out of the threaded hole.

[0060] In some embodiments, the cross-sectional shape of the rod member 53 can also be circular. Alternatively, the cross-sectional shape of the rod member 53 can also be polygonal. When the cross-sectional shape of the rod member 53 is polygonal, the rod member 53 has higher bending strength.

[0061] It can be understood that when the cross-sectional shape of the rod member 53 is polygonal, the part of the rod member 53 provided with the external thread still has a circular cross-sectional shape.

[0062] In some embodiments, an upper end of the rod member 53 is provided with a handle 531 facilitating rotation of the rod member 53, and the handle 531 is installed on the rod member 53 through key connection.

[0063] In some embodiments, the end cover 2 is provided with a recess accommodating the handle 531, and the recess is communicated with the threaded hole.

[0066] In some embodiments, the guide column 522 and the sliding part 52 are in an integrated structure.

[0067] In some embodiments, the fixing plate 41 is at least two, and the at least two fixing plates 41 are evenly distributed along the circumferential direction of the mounting seat 3.

[0068] It can be understood that the more the number of the fixing plates 41 is, the larger the contact area of the fixing plates 41 with the fixed object is. Therefore, the number of the fixing plates 41 can be determined according to the fixing strength requirement.

[0069] Meanwhile, the more the number of the fixing plates 41 is, the more uniform the stress of the mounting seat 3 is, and the mounting seat 3 is less likely to produce stress concentration, thereby making the mounting seat 3 less likely to be damaged.

[0070] The above has introduced the subject technical scheme of the utility model and the corresponding details, and it can be understood that the above introduction is only some implementation of the subject technical scheme of the utility model, and some details can be omitted in the specific implementation.

[0071] In addition, in some implementation of the above utility model, a plurality of implementation schemes can be combined, and various combination schemes are not listed one by one due to the length. The person skilled in the art can freely combine the above implementation schemes according to the needs in the specific implementation to obtain better application experience.

[0072] The person skilled in the art can obtain other detailed configurations or drawings according to the subject technical scheme of the utility model and the drawings in the implementation of the subject technical scheme of the utility model. Obviously, these details still belong to the range covered by the subject technical scheme of the utility model without departing from the subject technical scheme of the utility model.
