Description

Technical Field

[0001] The utility model relates to the technical field of mattresses, in particular to a sponge inflatable mattress. Background Art

[0002] Camping is a very popular outdoor leisure activity nowadays. Camping mattresses are also one of the important components of outdoor camping activities. Existing camping mattresses can be roughly divided into pure inflatable mattresses and sponge inflatable mattresses, each meeting the needs of different groups of people.

[0003] Existing sponge air mattresses usually consist of a cover cloth with TPU coated fabric, a PU sponge with a cutting structure inside, a base cloth with TPU coated fabric, some air nozzle valves and other accessories. Compared with pure inflatable products, sponge air mattresses with sponge have the advantages of softness, comfort, and warmth. However, the existing sponge air mattresses have a sponge filling structure inside. When inflated, a certain amount of air can be inhaled through the principle of sponge expansion. When storing, it is necessary to manually squeeze the gas inside the mattress repeatedly to expel the gas, and then store it in the storage bag. This process is very time-consuming and labor-intensive. The difficulty in rolling up and storing sponge air mattresses has become one of the important factors affecting the product experience, causing some users to choose other alternative products that are easier to store, reducing the market share of such products. Utility Model Content

[0004] The utility model aims to provide a sponge air mattress, which can assist the user in rolling up the sponge air mattress, thereby solving the problem that the existing sponge air mattress is difficult to roll up and store.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a sponge inflatable mattress, comprising an outer wrapped body, a sponge pad and an air pump, the outer wrapped body having an inflation cavity, the air pump being connected to the side wall of the outer wrapped body, the air pump being communicated with the inflation cavity, the air pump being used to inflate and deflate the inflation cavity, the sponge pad being arranged in the inflation cavity, the top surface of the sponge pad being concavely provided with a plurality of first grooves, the depth of the first grooves close to the air pump being greater than the depth of the first grooves away from the air pump.

[0007] Furthermore, each of the first grooves extends along a first direction and passes through both sides of the sponge pad along the first direction, the first direction is parallel to the top surface of the sponge pad, and multiple first grooves are arranged in sequence along a second direction, and the second direction is perpendicular to the first direction and parallel to the top surface of the sponge pad.

[0008] Furthermore, in any one of the first grooves, the depth of each location of the first groove is the same.

[0009] Furthermore, the air pump is connected to the side wall of the outer packaging body at one end along the second direction.

[0010] Furthermore, the depths of the first grooves are different, and the closer the first groove is to the air pump, the deeper the first groove is.

[0011] Furthermore, the projection of the inflation cavity toward the top surface of the sponge pad in the inflated state has a long side and a short side, the first direction is parallel to the short side, and the second direction is parallel to the long side.

[0012] Furthermore, the first groove is cut with a cross section perpendicular to the first direction, and the contour line of the shape obtained by cutting the first groove includes a straight line and / or a curve.

[0013] Further, the top surface of the sponge pad is concavely provided with at least one second groove extending along the first direction and / or at least one third groove extending along the first direction;

[0014] The second grooves are arranged between the plurality of first grooves along the second direction;

[0015] The third grooves are arranged between the first grooves along the second direction.

[0016] Furthermore, the bottom surface of the sponge pad is concavely provided with a plurality of fourth grooves extending along the first direction, the plurality of fourth grooves are arranged in sequence along the second direction at intervals, and the depth of each of the fourth grooves is less than the depth of each of the first grooves.

[0017] Furthermore, the outer packaging body includes a top layer, a bottom layer and a side wall, the top layer is connected to the bottom layer through the side wall, and the top layer, the bottom layer and the side wall are arranged to form the inflation cavity, and the air pump is connected to the side wall.

[0018] The sponge air-filled mattress provided by the utility model can produce the following beneficial effects:

[0019] When the sponge air mattress provided by the utility model is inflated, air can be inflated into the air chamber through an air pump, and the air quickly fills the air chamber, thereby realizing the rapid unfolding of the sponge air mattress. When the sponge air mattress needs to be rolled up, the air in the air chamber can be pumped out through an air pump. Since the air in the first groove is easier to be discharged than the air in the small hole in the sponge pad, the first groove is first to reach vacuum, and the side walls of the first groove have a tendency to fit each other. Since the sponge has a greater tension, it reaches vacuum later, resulting in different shrinkage rates between the top and bottom of the sponge air mattress, and the bottom edge is squeezed toward the top edge, so that the sponge bed can achieve the effect of automatically rolling up when air is pumped out, thereby assisting the user in rolling up the sponge air mattress. In addition, since the depth of the first groove close to the air pump is greater than the depth of the first groove far from the air pump, the sponge air mattress can be rolled up to the end, and the side close to the air pump can be wrapped as close as possible on the outside of the rolled-up part, forming a more compact roll structure.

[0020] Compared with the prior art, the sponge air mattress provided by the utility model can assist the user in rolling up the sponge air mattress, thereby solving the pain point of the difficulty in rolling and storing the existing sponge air mattresses and increasing the market share.

[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] This embodiment provides a sponge air mattress, such as Figure 1 to Figure 2 As shown, it includes an outer wrapping body 1, a sponge pad 2 and an air pump 3. The outer wrapping body 1 has an inflation cavity. The air pump 3 is connected to the side wall 13 of the outer wrapping body 1. The air pump 3 is communicated with the inflation cavity. The air pump 3 is used to inflate and discharge air into the inflation cavity. The sponge pad 2 is arranged in the inflation cavity. A plurality of first grooves 21 are concavely provided on the top surface of the sponge pad 2. The depth of the first groove 21 close to the air pump 3 is greater than the depth of the first groove 21 away from the air pump 3.

[0039] When the sponge inflatable mattress is used, air can be inflated into the inflation cavity through the air pump 3, and the air quickly fills the inflation cavity, thereby realizing the rapid expansion of the sponge inflatable mattress.

[0040] When the sponge inflatable mattress needs to be rolled up after use, the air in the inflation cavity can be pumped out by the air pump 3. Since the air in the first groove 21 is easier to be discharged than the air in the small holes in the sponge pad 2, the first groove 21 reaches vacuum first. The side walls of the first groove 21 tend to fit each other. Since the sponge has a greater tension, vacuum is reached later. Figure 3 and Figure 4 As shown, the top and bottom of the sponge inflatable mattress have different shrinkage rates, resulting in a phenomenon in which the bottom edge is squeezed toward the top edge, so that the sponge inflatable mattress can automatically roll up when air is pumped out, thereby assisting the user in rolling up the sponge inflatable mattress.

[0041] In addition, since the depth of the first groove 21 close to the air pump 3 is greater than the depth of the first groove 21 far from the air pump 3, the sponge air mattress can be rolled up to the end. Figure 5 As shown, the side close to the air pump 3 can be wrapped around the outside of the rolled portion as closely as possible to form a tighter rolled structure.

[0042] In an optional embodiment, if Figure 1As shown, each first groove 21 extends along the first direction and passes through both sides of the sponge pad 2 along the first direction. The first direction is parallel to the top surface of the sponge pad 2. Multiple first grooves 21 are arranged in sequence along the second direction. The second direction is perpendicular to the first direction and parallel to the top surface of the sponge pad 2.

[0043] In the above embodiment, each first groove 21 runs through both sides of the sponge pad 2 along the first direction, which can reduce the resistance encountered by the sponge pad 2 when rolling up, and is conducive to the automatic rolling up of the sponge pad 2. Multiple first grooves 21 are arranged in sequence along the second direction, which can make the sponge pad 2 have a more regular shape when rolling up.

[0044] The plurality of first grooves 21 may be arranged at equal intervals or at unequal intervals along the second direction.

[0045] In an optional embodiment, to facilitate the processing of the first groove 21 , in any first groove 21 , the depth of each part of the first groove 21 is the same.

[0046] In an optional embodiment, if Figure 1 As shown, the outer package body 1 has left and right ends along the second direction, and the air pump 3 is connected to the side wall 13 of one end of the outer package body 1 along the second direction.

[0047] by Figure 1 For example, the air pump 3 is connected to the side wall 13 at the left end of the outer package body 1 along the second direction. When in use, with the assistance of the air pump 3, the personnel can first roll up the end of the sponge air mattress away from the air pump 3. As the air pump 3 draws air, the sponge air mattress gradually rolls to the end close to the air pump 3, and the rolling is completed. Compared with the air pump 3 being connected to the side wall 13 at the upper end of the outer package body 1 along the first direction, it can be avoided as much as possible that the air pump 3 is first rolled into the inner layer during the rolling process, ensuring the normal operation of the air pump 3.

[0048] Among them, the air pump 3 can be as follows Figure 1 The device shown is arranged in the inflation cavity, and can also be arranged outside the inflation cavity to assist in completing the inflation and deflation process of the sponge inflatable mattress and reduce human intervention.

[0049] In an optional embodiment, if Figure 2 As shown, the depths of the first grooves 21 are different, and the closer the first groove 21 is to the air pump 3 , the deeper it is, that is, the depth of the first grooves 21 gradually increases as it approaches the air pump 3 .

[0050] In an optional embodiment, in order to facilitate the processing of the sponge air mattress, the depths of the first grooves 21 may also be the same.

[0051] In an optional embodiment, the projection of the inflation cavity toward the top surface of the sponge pad 2 in the inflated state is a rectangle having a long side and a short side, the first direction is parallel to the short side, and the second direction is parallel to the long side.

[0052] The above embodiment enables the sponge pad 2 to be rolled up along the long side of the sponge air mattress when it is automatically rolled up. The axial dimension of the rolled structure formed after rolling up is smaller, which is more convenient for users to store.

[0053] In an optional embodiment, the first groove 21 is cut with a cross section perpendicular to the first direction, and the contour line of the shape of the first groove 21 cut includes a straight line and / or a curve.

[0054] Specifically, the first groove 21 is cut with a cross section perpendicular to the first direction, and the contour line of the shape obtained by cutting the first groove 21 includes a straight line or a curve. Of course, the contour line of the shape obtained by cutting the first groove 21 may include both a straight line and a curve.

[0055] like Figure 2 As shown, the first groove 21 is cut with a cross section perpendicular to the first direction, and the shape of the first groove 21 cut can be a trapezoidal shape with a wide top and a narrow bottom; or as shown in FIG. Figure 6 As shown, the shape of the first groove 21 cut out can be a concave shape that first narrows, then widens, and finally narrows from top to bottom, and the contour line of the first groove 21 is composed of curves; or as shown in FIG. Figure 7 As shown, the shape of the first groove 21 after being cut can be approximately circular, and the arc corresponding to the contour line of the first groove 21 is the major arc.

[0056] Of course, the shape of the first groove 21 is not limited to the above shapes.

[0057] In an optional embodiment, if Figure 8 As shown, the top surface of the sponge pad 2 may also be provided with at least one second groove 22 extending along the first direction or at least one third groove 23 extending along the first direction, or the top surface of the sponge pad 2 may also be provided with at least one second groove 22 extending along the first direction and at least one third groove 23 extending along the first direction.

[0058] The second grooves 22 may be arranged between the plurality of first grooves 21 along the second direction, and the third grooves 23 may be arranged between the plurality of first grooves 21 along the second direction.

[0059] The sponge pad 2 is cut in a cross section perpendicular to the first direction, and the first groove 21, the second groove 22 and the third groove 23 are cut into different shapes. The above arrangement allows the top surface of the sponge pad 2 to be not limited to a groove structure with a single cross-sectional shape.

[0060] The first groove 21 may be cut into a trapezoidal shape that is wide at the top and narrow at the bottom, the second groove 22 may be cut into a rectangular shape, and the third groove 23 may be cut into a trapezoidal shape that is narrow at the top and wide at the bottom.

[0061] Of course, the shapes of the first groove 21 , the second groove 22 and the third groove 23 are not limited to the above examples.

[0062] In an optional embodiment, if Fig. 9 and Fig.10 As shown, the bottom surface of the sponge pad 2 is concavely provided with a plurality of fourth grooves 24 extending along the first direction, and the plurality of fourth grooves 24 are arranged in sequence along the second direction at intervals, and the depth of each fourth groove 24 is less than the depth of each first groove 21, so that after the air pump 3 is evacuated, the sponge pad 2 has a tendency to be squeezed from the bottom edge to the top edge.

[0063] The above arrangement can prevent the sponge pad 2 from being damaged due to the large pulling force on the bottom surface during the repeated winding process.

[0064] The fourth groove 24 may be in a semicircular, trapezoidal, triangular or rectangular shape, etc.

[0065] In a preferred embodiment, Fig.10 As shown, the projection of each fourth groove 24 on the top surface of the sponge pad 2 is located outside the projection of each first groove 21 on the top surface of the sponge pad 2 to prevent the sponge pad 2 from being too thin.

[0066] In an optional embodiment, if Fig.11 As shown, the portion of the sponge pad 2 between two adjacent first grooves 21 may be designed with a hollow structure 25 , and the hollow structure 25 may extend along a first direction and penetrate through both sides of the sponge pad 2 along the first direction.

[0067] The above arrangement can make the weight of the sponge air mattress smaller. When rolling up, the air in the hollow structure 25 can be drawn out first, assisting the sponge pad 2 to automatically roll up.

[0068] The hollow structure 25 is cut along a cross section perpendicular to the first direction, and the cut shape of the hollow structure 25 can be a triangle, a trapezoid, a circle, a square, or the like.

[0069] In a preferred embodiment, Fig.11 As shown, the first groove 21 and the hollow structure 25 are cut with a cross section perpendicular to the first direction. When the first groove 21 is cut into a trapezoidal shape that is narrow at the top and wide at the bottom, the hollow structure 25 is cut into a trapezoidal shape that is wide at the top and narrow at the bottom.

[0070] In an optional embodiment, if Figure 1As shown, the outer packaging body 1 includes a top layer 11, a bottom layer 12 and a side wall 13. The top layer 11 is connected to the bottom layer 12 through the side wall 13, and the top layer 11, the bottom layer 12 and the side wall 13 are arranged to form an inflation cavity, and the air pump 3 is connected to the side wall 13.

[0071] The top layer 11 , the bottom layer 12 and the side wall 13 are all made of existing TPU composite fabric or PVC fabric.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
