Technical Field
[0001] The utility model relates to the technical field of leather sponges, and specifically relates to a sponge leather composite product. Background Art
[0002] The current sponge leather composite products are made by stacking up and down. The leather and the sponge are bonded together with glue, and ventilation holes are provided on the leather. Exhaust gas is discharged through the gaps between the ventilation holes and the sponge. The leather and the sponge are connected by planar bonding.
[0003] However, the traditional bonding between the leather and the sponge is planar bonding. Although this bonding method is simple, gaps will be generated between the leather and the sponge during use, and thus the connection between the leather and the sponge is unstable. In addition, foreign objects are likely to fall into the ventilation holes on the leather, making it difficult to clean.
[0004] To solve the above problems, a sponge leather composite product is proposed in this application. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sponge leather composite product, including leather and sponge, the leather and the sponge are bonded and connected by glue, ventilation holes are provided on the leather, and further includes: a fixing strip, the fixing strip is fixedly connected to the lower end of the leather, a fixing groove is provided at the upper end of the sponge, the fixing strip is matched with the fixing groove, glue is also applied in the fixing groove, and the fixing area can be increased through the fixing strip and the fixing groove; a filter screen, the filter screen is arranged between the leather and the sponge, a convex strip is fixedly connected to the upper end of the sponge, and the filter screen is arranged at the upper end of the convex strip.
[0007] A further technical improvement of the utility model is that the ventilation holes penetrate through the sponge and are corresponding to the position of the convex strip.
[0008] A further technical improvement of the utility model is that a groove is provided at the lower end of the leather, the groove is matched with the convex strip, and glue is applied in the groove.
[0009] A further technical improvement of the utility model is that a through communication hole is provided on the side of the sponge, and the communication hole also penetrates through the fixing strip.
[0010] A further technical improvement of the utility model is that the number of the communication holes is multiple, and the communication holes are corresponding to and matched with the positions of the ventilation holes.
[0011] A further technical improvement of the present utility model lies in that the lower end of the fixing strip is arc-shaped.
[0012] Compared with the above background art, the sponge-leather composite provided by this application includes leather and sponge with very mature technologies nowadays, as well as fixing strips and filter meshes as the core components. Its principle relies on increasing the bonding area between the leather and the sponge through the fixing strips, thereby improving the bonding stability. Moreover, foreign objects falling on the leather fall onto the filter mesh through the ventilation holes, preventing foreign objects from entering between the leather and the sponge and facilitating cleaning.
[0013] The embodiment of the present utility model provides a sponge-leather composite, which has the following beneficial effects:
[0014] This new type is applied to the sponge-leather composite. By setting the fixing strips and the filter mesh, a stable bonding effect is formed between the leather and the sponge through the fixing strips and the fixing grooves, as well as the grooves and the protruding strips, preventing the leather and the sponge from delaminating during use, increasing the bonding contact area, and facilitating the cleaning of the leather through the filter mesh. When foreign objects fall onto the filter mesh through the ventilation holes, they will not enter between the leather and the sponge. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a sponge leather composite product, including a fixing strip 7 fixed to the lower end of the leather 1. When the leather 1 and the sponge 2 are adhesively bonded, the fixing strip 7 is inserted into the fixing groove 9. Glue is applied in the fixing groove 9. When the fixing strip 7 is inserted into the fixing groove 9, the glue is squeezed and evenly applied. Thus, the connection stability between the leather 1 and the sponge 2 can be increased through the fixing strip 7 and the fixing groove 9. Ventilation holes 5 are provided on the leather 1, and the ventilation holes 5 penetrate through the leather 1 and the sponge 2. A filter screen 6 is placed at the end of the convex strip 4 on the sponge 2. When foreign objects from the outside fall into the ventilation holes 5 through the ventilation holes 5, they are intercepted by the filter screen 6, preventing the foreign objects from falling between the leather 1 and the sponge 2. In this way, the connection stability between the leather 1 and the sponge 2 is improved, and the filter screen 6 can prevent foreign objects from falling between the leather 1 and the sponge 2, facilitating the cleaning of the leather 1 and the sponge 2.
[0024] In addition, a groove 3 is provided at the lower end of the leather 1, and a convex strip 4 is fixed to the upper end of the sponge 2. The groove 3 matches the convex strip 4, and glue is applied in the groove 3, further improving the stability between the leather 1 and the sponge 2. A communication hole 8 is provided on the side of the sponge 2, and the communication hole 8 penetrates through the sponge 2 and the fixing strip 7, and the communication hole 8 is communicated with the ventilation hole 5. Thus, the air permeability of the sponge 2 and the leather 1 is further improved. The lower end of the fixing strip 7 is arc-shaped. During use, the arc of the fixing strip 7 enables rapid rebound, improving the elasticity of the leather 1 and the sponge 2.
[0025] During manufacturing and use, glue is applied in both the groove 3 and the fixing groove 9. The leather 1 is placed on the sponge 2, and the fixing strip 7 and the convex strip 4 match the fixing groove 9 and the groove 3. In this way, the glue inside the groove 3 and the fixing groove 9 is evenly squeezed, further improving the connection stability between the leather 1 and the sponge 2. A filter screen 6 is placed on the convex strip 4, and the filter screen 6 can be directly seen through the ventilation hole 5 at the upper end of the leather 1. When foreign objects fall on the filter screen 6, it is convenient to clean the leather 1.
