Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0029] The present invention provides a composite pure wood pulp paper as Figures 1-3 shown, which includes a wood pulp paper body 1, an outer layer paper 2, a strengthening mechanism 3 and a protection mechanism 4. The wood pulp paper body 1 is made of wood fiber materials and is used for cleaning liquids. The outer layer paper 2 is arranged at the top and bottom of the wood pulp paper body 1. The outer layer paper 2 is arranged outside the wood pulp paper body 1 and is used for absorbing and cleaning liquids. The strengthening mechanism 3 is arranged inside the wood pulp paper body 1. The strengthening mechanism 3 is used to form a water-absorbing structure inside the wood pulp paper body 1 and absorb and store liquids. By means of the strengthening mechanism 3, the liquid absorption capacity of the wood pulp paper body 1 is improved, and the water absorption performance of the wood pulp paper body 1 is increased. The protection mechanism 4 is arranged on the wood pulp paper body 1. The protection mechanism 4 is used to form a barrier structure on the wood pulp paper body 1 and protect the wood pulp paper body 1. By means of the protection mechanism 4, the tear resistance of the wood pulp paper body 1 is increased, the wood pulp paper body 1 is protected, and the use of the wood pulp paper body 1 is facilitated.

[0030] Specifically, the strengthening mechanism 3 includes an inner layer of paper 31, a water-absorbing paper layer 32, transverse grooves 33, and longitudinal grooves 34. The inner layer of paper 31 is disposed in the middle of the wood pulp paper body 1. The inner layer of paper 31 is disposed between the outer layers of paper 2. The inner layer of paper 31 and the outer layers of paper 2 form the wood pulp paper body 1, which is used to enhance the absorption and storage capacity of the wood pulp paper body 1 for liquids and ensure the convenience of use of the wood pulp paper body 1. The water-absorbing paper layer 32 is disposed at the top and bottom of the inner layer of paper 31. The outer wall of the water-absorbing paper layer 32 is fitted to the inner side wall of the outer layer of paper 2. The water-absorbing paper layer 32 is used to absorb liquids and store the liquids. The transverse grooves 33 are disposed on the outer side wall of the water-absorbing paper layer 32. The inner cavity of the transverse grooves 33 is used to store liquids, thereby increasing the storage capacity of the inner layer of paper 31 for liquids and improving the water absorption performance of the inner layer of paper 31. The transverse grooves 33 are arranged in a straight line at equal intervals. The longitudinal grooves 34 are disposed on the inner side wall of the outer layer of paper 2. The longitudinal grooves 34 are arranged in a straight line at equal intervals. The inner cavity of the longitudinal grooves 34 is used to store liquids, thereby improving the water absorption capacity of the outer layer of paper 2. Moreover, the arrangement of the transverse grooves 33 and the longitudinal grooves 34 ensures the contact area between the outer layer of paper 2 and the inner layer of paper 31 and guarantees the stability of the wood pulp paper body 1. The outer layer of paper 2 outside the wood pulp paper body 1 absorbs liquids, and the liquids enter the inner layer of paper 31 inside the wood pulp paper body 1. The water-absorbing paper layer 32 is used to absorb the liquids and store the liquids in the inner cavities of the transverse grooves 33 and the longitudinal grooves 34, thereby increasing the storage capacity of the outer layer of paper 2 and the inner layer of paper 31 and enhancing the water absorption performance of the wood pulp paper body 1.

[0031] Furthermore, the protection mechanism 4 includes a reinforced paper layer 41, water permeable holes 42, a wet strength coating 43, and a softness coating 44. The reinforced paper layer 41 is disposed at the middle position of the inner layer paper 31. By utilizing the fiber-rich characteristics of coniferous tree fibers, the toughness and tear resistance of the inner layer paper 31 are enhanced, preventing the tearing phenomenon during the use of the wood pulp paper main body 1, improving the practicality of the wood pulp paper main body 1. The reinforced paper layer 41 is disposed between the water absorbent paper layers 32. The water permeable holes 42 are provided on the reinforced paper layer 41. The water permeable holes 42 are evenly distributed at equal intervals and are through holes for the flow of liquid. The liquid flows through the inner cavity of the water permeable holes 42 to ensure the water permeability on both sides of the reinforced paper layer 41. The wet strength coating 43 is disposed on the outer wall of the outer layer paper 2. The wet strength coating 43 is made of PAE wet strength agent material. By dipping the wood pulp paper main body 1 in the PAE wet strength agent solution, a wet strength coating 43 is formed on the outer layer paper 2, improving the water absorption of the wood pulp paper main body 1 and ensuring high wet strength of the wood pulp paper main body 1. The softness coating 44 is disposed on the outer wall of the wet strength coating 43. The softness coating 44 is made of softening agent material. By dipping the wood pulp paper main body 1 in the softening agent solution, a softness coating 44 is formed on the outer layer paper 2, improving the softness of the wood pulp paper main body 1 and ensuring the comfort during the use of the wood pulp paper main body 1. The reinforced paper layer 41 is made of coniferous wood fibers. By utilizing its fiber-rich characteristics, the toughness and tear resistance of the inner layer paper 31 are enhanced, preventing the tearing phenomenon during the use of the wood pulp paper main body 1, improving the practicality of the wood pulp paper main body 1. And the liquid flows through the inner cavity of the water permeable holes 42 to ensure the water permeability on both sides of the reinforced paper layer 41, facilitating the absorption of liquid by the wood pulp paper main body 1.

[0032] Both the outer layer paper 2 and the water absorbent paper layer 32 are made of lignocellulose materials, using the gaps between cellulose to store liquid. The reinforced paper layer 41 is made of coniferous tree fiber materials. The transverse grooves 33 and the longitudinal grooves 34 are perpendicular to each other. The transverse grooves 33 and the longitudinal grooves 34 are formed on the outer layer paper 2 and the water absorbent paper layer 32 by means of die pressing. The outer layer paper 2 and the inner layer paper 31 are connected by adhesion.
