Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive beauty technology, and more specifically, to a sponge for automotive interiors. Background Technology
[0002] With the rapid development of the automotive industry, the cleaning and maintenance of car interiors are receiving increasing attention from car owners. Now, sponges are being used as cleaning tools to clean car interiors.
[0003] For example, the cleaning sponge disclosed in patent announcement number CN216932907U includes at least two first sponge layers and at least two second sponge layers, wherein the at least two first sponge layers and the at least two second sponge layers are staggered and stacked along a first direction, and the water absorption of the second sponge layer is stronger than that of the first sponge layer.
[0004] As mentioned above, when it is necessary to clean the air conditioning vents on the car interior, the sponge in this patent has a flat surface, while the air conditioning vents are uneven, making it impossible for the sponge to fit the air conditioning vents and remove the dust from them, resulting in poor cleaning effect. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sponge wiper for automotive interiors that improves wiping effect.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A sponge for automotive interiors includes a filter sponge, seaweed sponge, and wood pulp sponge.
[0008] The filter sponge and wood pulp foam were placed on either side of the seaweed foam.
[0009] Both the filter sponge and the wood pulp sponge are glued and fixed to the seaweed sponge.
[0010] The filter sponge has several raised layers, which are glued to the filter sponge.
[0011] Several grooves are formed on the raised layer.
[0012] The filter sponge has several slots, which are placed between adjacent grooves.
[0013] The present invention is further configured such that the inclination angle of the groove is smaller than the inclination angle of the slot opening.
[0014] The present invention is further configured such that both the protrusion and the groove are inclined.
[0015] The present invention is further configured such that the distance between the groove and the filter sponge is greater than the depth of the groove opening.
[0016] The present invention is further configured such that: one side of the filter sponge, seaweed sponge and wood pulp sponge are provided with an opening, and the other side is provided with a connecting layer, the opening is arc-shaped and the connecting layer is planar.
[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0018] By setting a raised layer, the raised layer can wipe the inner wall of the air conditioner vent more deeply. The grooves on the raised layer and the slots on the filter sponge allow the sides of the grooves and slots to better fit the air conditioner vent, wiping away the dust on the air conditioner vent and thus improving the wiping effect. Because the distance between the grooves and the filter sponge is greater than the depth of the slots, the contact area with the air conditioner vent is increased. Attached Figure Description
[0019] Figure 1 This is a perspective view of an embodiment of the present utility model;
[0020] Figure 2 This is a bottom view of an embodiment of the present utility model.
[0021] Filter sponge 1, seaweed sponge 2, wood pulp sponge 3, raised layer 4, groove 5, slot 6, opening 7, connecting layer 8. Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] like Figures 1 to 2 As shown, the sponge wiper used for automotive interiors includes a filter sponge 1, a seaweed sponge 2, and a wood pulp sponge 3. The seaweed sponge 2 is located between the filter sponge 1 and the wood pulp sponge 3. One side of the seaweed sponge 2 is glued to the filter sponge 1, and the other side is glued to the wood pulp sponge 3.
[0025] The first layer of filter sponge effectively blocks impurities from entering the sponge, extending its service life. The third layer of wood pulp sponge provides excellent softness and absorbency, improving the wiping effect. The second layer of seaweed sponge improves the sponge's liquid absorption and retention, resulting in a more even distribution of liquid during wiping.
[0026] The filter sponge 1, seaweed sponge 2 and wood pulp sponge 3 each have an opening 7 on one side and a connecting layer 8 on the other side. The opening 7 is arc-shaped and the connecting layer 8 is flat. The connecting layer 8 wipes the flat surface of the car interior, and the opening 7 wipes the uneven parts of the car interior surface.
[0027] The filter sponge 1 has several raised layers 4, which are glued to the filter sponge 1. Several grooves 5 are formed on the raised layers 4, and several slots 6 are formed on the filter sponge 1. The slots 6 are placed between adjacent grooves 5. Because the user holds the sponge at an angle during wiping and wipes the air conditioner vent, the wiping is more even because both the raised layers 4 and the slots 6 are angled.
[0028] The raised layer 4, the groove 5 and the slot 6 form an undulating surface. The inclination angle of the groove 5 is smaller than that of the slot 6, which further improves the wiping effect. The distance between the groove 5 and the filter sponge 1 is greater than the depth of the slot 6, which increases the contact area with the air conditioner outlet.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
