Title: Quick-detachable and replaceable wet tissue flap cover

Description:
TECHNICAL FIELD 
     The invention relates to a flap cover, in particular to a quick-detachable and replaceable wet tissue flap cover. 
     DESCRIPTION OF THE RELATED ART 
     Each of existing wet tissue flap covers comprises an upper flap cover and a lower withdrawal cover, and the upper flap cover and the lower withdrawal cover are mainly connected in the following two modes: 
     1. The upper flap cover and the lower withdrawal cover are integrated to form a collapsible connection. The disadvantage is that the connection breaks after repeated turnover or pull. Once the connection breaks, the upper flap cover and the lower withdrawal cover are separated and can not be replaced, thereby seriously affecting the tightness of the wet tissue flap cover. 
     2. The upper flap cover and the lower flap cover are connected by a connecting shaft or connecting rod. After repeated use, the connecting shaft or connecting rod breaks easily, thus, the upper flap cover and the lower flap cover cannot be connected and replaced. 
     The wet tissue flap covers of the above two structures have such problems when used, as a result, the upper flap cover and the lower withdrawal cover are separated and cannot be connected again, which will seriously affect the tightness of the wet wipe flap covers, result in moisture loss of wet tissues, and affect the use effect of wet tissues, resulting in bacteria breeding, and affecting the safety and hygiene of wet tissues. 
     SUMMARY OF THE INVENTION 
     Due to the problems in the prior art, the invention provides a quick-detachable and replaceable wet tissue flap cover to prevent connection failure, moisture loss of wet tissues and bacteria breeding due to separation of an upper flap cover from a lower withdrawal cover. 
     The invention solves the problems by the following technical solution: 
     A quick-detachable and replaceable wet tissue flap cover, comprising an upper flap cover and a lower withdrawal cover, and characterized in that a hinge structure is arranged at a joint between said upper flap cover and said lower withdrawal cover, a clamping slot connected with said hinge structure is arranged at the joint between said lower withdrawal cover and said upper flap cover, said clamping slot is elastically clamped with said hinge structure, and said upper flap cover is reversibly open and closed relative to said lower withdrawal cover. 
     Preferably, said hinge structure comprises two parallel support portions and a hinge shaft with both ends fixed at said support portions respectively, and said support portions are fixed at the joint between the upper flap cover and the lower withdrawal cover; said hinge shaft is a cylindrical rod arranged at a spacing from said upper flap cover, and said clamping slot is extended in the spacing and elastically clamped with said hinge shaft. 
     Preferably, said clamping slot is integrated with said lower withdrawal cover by an elastic material, an opening of said clamping slot faces downward, and said hinge shaft is inserted into or pulled out of the opening. 
     Preferably, an oval wet tissue withdrawal opening is formed on said lower withdrawal cover, a raised ring wall is formed at an edge of said withdrawal opening, and an upper surface of said ring wall is closely fitted with a lower surface of said upper flap cover when said upper flap cover and said lower withdrawal cover are closed, preventing ingress of external dust and impurities, and keeping wet tissues clean and sanitary. 
     With the technical means, the application improves the connecting structure between the upper flap cover and the lower withdrawal cover. The arrangement of the hinge structure and the clamping slot on said upper flap cover and said lower withdrawal cover respectively helps avoid the problems that the upper flap cover and the lower withdrawal cover of an existing wet tissue flap cover break easily and cannot be replaced, and realize quick detachment and replacement of the wet tissue flap cover, thus guaranteeing the tightness, safety and hygiene of the wet tissue flap cover, avoiding bacteria breeding and moisture loss of wet tissues, and guaranteeing the use effect of wet tissues by users.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The technical solution of the invention will be further described in detail in combination with examples and drawings. 
     As shown in  FIG. 1  and  FIG. 2 , a quick-detachable and replaceable wet tissue flap cover of the invention comprises an upper flap cover  1  and a lower withdrawal cover  2 . A hinge structure  11  is arranged at a joint between said upper flap cover  1  and said lower withdrawal cover  2 , a clamping slot  21  connected with said hinge structure  11  is arranged at the joint between said lower withdrawal cover  2  and said upper flap cover  1 , said clamping slot  21  is elastically clamped with said hinge structure  11 , and said upper flap cover  1  is reversibly open and closed relative to said lower withdrawal cover  2 . 
     Said hinge structure  11  comprises two parallel support portions  111  and a hinge shaft  112  with both ends fixed at said support portions  111  respectively, and said support portions  111  are fixed at the joint between the upper flap cover  1  and the lower withdrawal cover  2 ; said hinge shaft  112  is a cylindrical rod arranged at a spacing from said upper flap cover  1 , and said clamping slot  21  is extended in the spacing and elastically clamped with said hinge shaft  112 . 
     Said clamping slot  21  is integrated with said lower withdrawal cover  2  by an elastic material, an opening of said clamping slot  21  faces downward, and said hinge shaft  112  is inserted into or pulled out of the opening. 
     An oval wet tissue withdrawal opening is formed on said lower withdrawal cover  2 , a raised ring wall  22  is formed at an edge of said withdrawal opening, and an upper surface of said ring wall  22  is closely fitted with a lower surface of said upper flap cover  1  when said upper flap cover  1  and said lower withdrawal cover  2  are closed, preventing ingress of external dust and impurities, and keeping wet tissues clean and sanitary. 
     With the technical means, the application improves the connecting structure between the upper flap cover  1  and the lower withdrawal cover  2 . The arrangement of the hinge structure  11  and the clamping slot  21  on said upper flap cover  1  and said lower withdrawal cover  2  respectively helps avoid the problems that the upper flap cover  1  and the lower withdrawal cover  2  of an existing wet tissue flap cover break easily and cannot be replaced, and realize quick detachment and replacement of the wet tissue flap cover, thus guaranteeing the tightness, safety and hygiene of the wet tissue flap cover, avoiding bacteria breeding and moisture loss of wet tissues, and guaranteeing the use effect of wet tissues by users. 
     Such embodiments are only used to describe the invention, but not limit the scope thereof. Any equal changes and modifications made to the invention by a person skilled in the art shall fall into the scope of claims attached to the invention.
