Description

Technical Field

[0001] The utility model relates to an inflatable mattress and belongs to the technical field of inflatable mattresses. Background Art

[0002] Inflatable mattresses can be inflated and used as beds and mattresses, and can also be folded up when not in use for easy storage, getting rid of the defects of traditional mattresses that are bulky and difficult to store. Therefore, inflatable mattresses have been favored by consumers because of their good comfort, light weight, foldability, and easy carrying.

[0003] The existing inflatable mattresses generally control the air pressure inside the inflatable mattress through an inflation mechanism when in use, and the hardness of the mattress can be adjusted through the inflation mechanism. However, the hardness of the inflatable mattress is mainly adjusted in the middle area of ​​the inflatable mattress. The edges of the inflatable mattress often collapse during use, and the body may even slip off. In order to solve the problem of edge collapse of the inflatable mattress, a bed guard made of sponge, plastic, wood or other materials with higher hardness is generally set on the periphery of the inflatable mattress, and the inflatable mattress is placed in the bed guard. Although the body can be prevented from slipping off by the bed guard with higher hardness, when the body touches the edge of the inflatable mattress, the inflatable mattress will still have the problem of partial collapse, affecting the comfort of the inflatable mattress. The bed guard with higher hardness will also affect the overall aesthetics of the inflatable mattress, and it is not convenient to store and organize the inflatable mattress. Summary of the invention

[0004] The utility model aims at the deficiencies in the prior art and provides an air-filled mattress.

[0005] The utility model solves the above technical problems with the following technical solutions: an inflatable mattress, comprising a mattress body and an inflatable mechanism for supplying air to the mattress body, the mattress body comprising an inflatable cushion and an inflatable bed surround arranged on the side of the inflatable cushion, the inflatable mechanism being connected to the inflatable cushion through an air supply pipeline;

[0006] A connecting pipeline is provided between the inflatable cushion and the inflatable bed surround, and a pipeline valve is provided on the connecting pipeline. The pipeline valve is used to allow the gas of the inflatable cushion to enter the inflatable bed surround and prevent the gas of the inflatable bed surround from flowing back into the inflatable cushion.

[0007] The beneficial effects of the utility model are as follows: when the body is located at the edge of the inflatable mattress, that is, when the body acts on the inflatable bed surround, the air pressure in the inflatable bed surround surges, the connecting pipeline between the inflatable bed surround and the inflatable cushion can be closed, and the high-pressure state of the inflatable bed surround is maintained. The edge of the inflatable mattress and the contact part of the body still maintain the original surface tension and air pressure, the edge of the inflatable mattress does not collapse, and is sufficient to effectively support the body; the inflatable mattress structure eliminates the need for a harder bed surround, and the inflatable bed surround and the inflatable cushion can be folded, and the volume of the logistics transportation packaging will be effectively reduced.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the inflatable mattress is of a rectangular structure; the inflatable bed surround is arranged at one side of the inflatable mattress, and the inflatable bed surround is in a straight-line structure; or, the inflatable bed surround is arranged at two adjacent sides of the inflatable mattress, and the inflatable bed surround is in an L-shaped structure; or, the inflatable bed surround is arranged at three adjacent sides of the inflatable mattress, and the inflatable bed surround is in a U-shaped structure.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the inflatable bed surround can be set on one side, two adjacent sides and three sides of the inflatable mattress with a rectangular structure, which can meet the needs of various different placement positions of the inflatable mattress. For example, when the inflatable mattress is placed in a structure with three walls, an inflatable bed surround with a straight-line structure can be used to ensure that the side of the inflatable mattress that the body can contact does not collapse; if the inflatable mattress is placed in a position with two adjacent walls, an inflatable bed surround with an L-shaped structure can be used to ensure that the two edges of the inflatable mattress do not collapse; of course, an inflatable bed surround with a U-shaped structure can also be used, which is set on three sides of the inflatable mattress to ensure that the three edges of the inflatable mattress do not collapse and can effectively support the body; the remaining one side of the inflatable mattress can be used as the head position, and the pipeline connection between the inflatable mattress and the inflation mechanism, and the inflatable mattress and the inflatable bed surround can be set here, which also facilitates the maintenance of the pipeline, valves and inflation mechanism.

[0011] Furthermore, the inflation mechanism includes an inflation pump, and the inflation pump is connected to the inflatable cushion through the air supply pipeline.

[0012] The beneficial effect of adopting the above further solution is that the air pump can supply air to the inflatable cushion through the air supply pipeline, thereby meeting the air supply demand of the inflatable mattress.

[0013] Furthermore, the pipeline valve adopts a non-return one-way valve, and the reverse cut-off opening pressure of the non-return one-way valve is 0.5-1.5 KPa.

[0014] The beneficial effect of adopting the above further scheme is that the pipeline valve can adopt a non-return one-way valve, and the minimum reverse pressure of the non-return one-way valve is set, that is, the reverse cut-off opening pressure. When the difference between the air pressure in the inflatable bed enclosure and the air pressure in the inflatable cushion is greater than the reverse cut-off opening pressure of the pipeline valve, the pipeline valve will prevent the gas in the inflatable bed enclosure from flowing to the inflatable cushion. Under normal circumstances, the air pressure in the inflatable bed enclosure and the inflatable cushion is balanced. Only when the body acts on the inflatable bed enclosure, such as pressing on the inflatable bed enclosure, the pressure difference between the inflatable bed enclosure and the inflatable cushion will quickly exceed the minimum reverse pressure, which plays a role in keeping the inflatable mattress from collapsing and being able to support the body.

[0015] Furthermore, the pipeline valve is a stop valve.

[0016] The beneficial effect of adopting the above further scheme is that the pipeline valve can also adopt a stop valve, and the stop valve is in a normally open state. After the inflatable cushion is inflated, the human body presses on the inflatable cushion, so that the air pressure in the inflatable bed surround rises, and then the stop valve is closed, so that the inflatable bed surround is in a relatively high-pressure state. When the human body contacts the inflatable bed surround, the inflatable bed surround can not collapse, so as to achieve the function of supporting the body. When the air pressure in the inflatable bed surround decreases for some reason, the above action can be repeated, that is, the stop valve is opened, the human body presses on the inflatable cushion, so that the air pressure in the inflatable bed surround rises, and then the stop valve is closed, so that the pressure in the inflatable bed surround is in a relatively high-pressure state compared with the inflation pressure; when the stop valve is used without load and the temperature change is small, the air pressure in the inflatable bed surround is maintained relatively unchanged, avoiding excessive load changes of the inflatable cushion, such as the influence of two people on the same bed, and maintaining the inflatable bed surround with appropriate hardness.

[0017] Furthermore, the inflatable bed surround and the inflatable cushion are an integrated structure.

[0018] The beneficial effect of adopting the above further solution is that the inflatable mattress has an integrated structure, and the connection between the inflatable bed guard and the inflatable cushion is better, and the two are not easily separated.

[0019] Furthermore, a separator is provided in the mattress body, and the separator separates the mattress body into the inflatable bed surround and the inflatable cushion.

[0020] The beneficial effect of adopting the above further solution is that, for an inflatable mattress with an integrated structure, an inflatable bed guard and an inflatable cushion can be formed by separation of a partition sheet, so that the edge of the inflatable mattress does not collapse and can support the body.

[0021] Furthermore, two mattress bodies are provided, each of which includes an inflatable cushion with a rectangular structure and an inflatable bed surround with an L-shaped structure. The two mattress bodies are connected by the inflatable cushion, and two inflatable bed surrounds with L-shaped structures are spliced ​​to form an inflatable bed surround with a U-shaped structure. The inflation mechanism is connected to the two inflatable cushions through air supply pipelines.

[0022] The beneficial effect of adopting the above further scheme is that the inflatable mattress can be spliced ​​into a large inflatable mattress by splicing two inflatable mattresses according to usage requirements. For example, a single inflatable mattress can be spliced ​​into an inflatable mattress for double use.

[0023] Furthermore, adjacent inflatable cushions are connected by zippers.

[0024] The beneficial effect of adopting the above further solution is that adjacent inflatable cushions can be spliced ​​together by zippers, which is not only convenient for connection but also for subsequent maintenance.

[0025] Furthermore, adjacent inflatable cushions are glued and spliced ​​together.

[0026] The beneficial effect of adopting the above further solution is that adjacent inflatable cushions can also be glued together to achieve connection between adjacent inflatable cushions. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Embodiment 1, as Figure 1 and Figure 2 As shown, an inflatable mattress comprises a mattress body and an inflatable mechanism for supplying air to the mattress body, wherein the mattress body comprises an inflatable cushion 1 and an inflatable bed surround 2 arranged on the side of the inflatable cushion 1, and the inflatable mechanism is connected to the inflatable cushion 1 through an air supply pipeline 6;

[0034] A connecting pipe 3 is provided between the air chamber of the inflatable cushion 1 and the air chamber of the inflatable bed surround 2. A pipe valve is provided on the connecting pipe 3. The pipe valve is used to allow the gas of the inflatable cushion 1 to enter the inflatable bed surround 2 and prevent the gas of the inflatable bed surround 2 from flowing back into the inflatable cushion 1.

[0035] The inflatable mattress is of a rectangular structure; the inflatable bed surround is arranged at one side of the inflatable mattress, and the inflatable bed surround is in a straight line structure; or, the inflatable bed surround is arranged at two adjacent sides of the inflatable mattress, and the inflatable bed surround is in an L-shaped structure; or, the inflatable bed surround is arranged at three adjacent sides of the inflatable mattress, and the inflatable bed surround is in a U-shaped structure. The inflatable bed surround can be set on one side, two adjacent sides and three sides of the inflatable mattress with a rectangular structure, which can meet the needs of various different placement positions of the inflatable mattress. For example, when the inflatable mattress is placed in a structure with three walls, an inflatable bed surround with a straight-line structure can be used to ensure that the side of the inflatable mattress that the body can contact does not collapse; if the inflatable mattress is placed in a position with two adjacent walls, an inflatable bed surround with an L-shaped structure can be used to ensure that the two edges of the inflatable mattress do not collapse; of course, an inflatable bed surround with a U-shaped structure can also be used, which can be set on three sides of the inflatable mattress to ensure that the three edges of the inflatable mattress do not collapse and can effectively support the body; the remaining one side of the inflatable mattress can be used as the head position, and the pipeline connection between the inflatable mattress and the inflation mechanism, and the inflatable mattress and the inflatable bed surround can be set here, which also facilitates the maintenance of the pipeline, valves and inflation mechanism.

[0036] The inflation mechanism includes an inflation pump 5, and the inflation pump 5 is connected to the inflatable cushion 1 through an air supply pipeline 6. The inflation pump 5 can supply air to the inflatable cushion 1 through the air supply pipeline 6, and can meet the air supply demand of the inflatable mattress.

[0037] The pipeline valve adopts a check valve 4, and the reverse cut-off opening pressure of the check valve 4 is 0.5-1.5KPa. The pipeline valve can adopt a check valve 4, and the minimum reverse pressure of the check valve 4 is set, that is, the reverse cut-off opening pressure. When the difference between the air pressure in the inflatable bed enclosure 2 and the air pressure in the inflatable cushion 1 is greater than the reverse cut-off opening pressure of the pipeline valve, the pipeline valve will prevent the gas in the inflatable bed enclosure 2 from flowing to the inflatable cushion 1. After setting the minimum reverse pressure of the check valve 4 to 1Kpa, under normal circumstances, the air pressure in the inflatable bed enclosure 2 and the inflatable cushion 1 is balanced. Only when the body acts on the inflatable bed enclosure 2, such as pressing on the inflatable bed enclosure 2, the pressure difference between the inflatable bed enclosure 2 and the inflatable cushion 1 will quickly exceed the set reverse pressure of 1Kpa, which plays a role in keeping the inflatable mattress from collapsing and achieving the function of supporting the body.

[0038] The inflatable bed surround 2 is an integrated structure with the inflatable mattress 1. The inflatable mattress has an integrated structure, and the connection effect between the inflatable bed surround 2 and the inflatable mattress 1 is better, and the two are not easily separated.

[0039] The mattress body is provided with a separator, which separates the mattress body into an inflatable bed surround 2 and an inflatable cushion 1. For an inflatable mattress with an integrated structure, the inflatable bed surround 2 and the inflatable cushion 1 can be separated by the separator, so that the edge of the inflatable mattress does not collapse and can support the body.

[0040] Embodiment 2, as Figure 3 and Figure 4 As shown, the mattress body is provided with two, each of which includes the inflatable cushion 1 of rectangular structure and the inflatable bed surround 2 of L-shaped structure, the two mattress bodies are connected by the inflatable cushion 2, the two inflatable bed surrounds 2 of L-shaped structure are spliced ​​to form the inflatable bed surround 2 of U-shaped structure, and the inflatable mechanism is respectively connected to the two inflatable cushions 1 through the air supply pipeline 6. The inflatable mattress can be formed according to the use requirements, such as connecting two single inflatable cushions 1 through the middle inflatable cushion to form a double mattress. The air pump supplies air to one inflatable cushion through an air supply pipeline, and supplies air to another inflatable cushion through another air supply pipeline. The inflatable cushion of each mattress body is connected to its L-shaped inflatable bed surround through a connecting pipeline, and there is a pipeline valve on the connecting pipeline.

[0041] The adjacent inflatable cushions 1 are spliced ​​together by zippers 7. The adjacent inflatable cushions 1 can be spliced ​​together by zippers 7, which is not only convenient for connection, but also convenient for subsequent maintenance.

[0042] The adjacent inflatable cushions 1 are pasted and spliced ​​together. The adjacent inflatable cushions 1 can also be glued together to achieve the connection between the adjacent inflatable cushions 1.

[0043] In Example 3, the pipeline valve adopts a stop valve. The pipeline valve can also adopt a stop valve, which is in a normally open state. After the air cushion is inflated, the human body presses on the air cushion, causing the air pressure in the air cushion to rise, and then the stop valve is closed, so that the air cushion is in a relatively high-pressure state. When the human body contacts the air cushion, the air cushion will not collapse, so as to support the body. When the air pressure in the air cushion decreases for some reason, the above-mentioned action can be repeated, that is, the stop valve is opened, the human body presses on the air cushion, causing the air pressure in the air cushion to rise, and then the stop valve is closed, so that the pressure in the air cushion is in a relatively high-pressure state compared with the inflation pressure; when the stop valve is used without load and the temperature change is small, the air pressure in the air cushion is kept relatively unchanged to avoid excessive load changes of the air cushion, such as the influence of two people on the same bed, and the hardness of the air cushion is maintained appropriately. The remaining structure is the same as that of Example 1, and will not be described here.

[0044] The research results show that when a person sleeps on an air mattress, the gravity acting on the body is balanced by the uniform force of the air pressure in the air mattress and the surface tension of the air mattress, wherein the surface tension of the air mattress depends on the thickness and air pressure of the air mattress. When the body is located at the edge of the air mattress, the air mattress in contact with the body becomes thinner, loses part or all of the surface tension, and is insufficient to support the body, causing the air mattress to collapse. The combined force of the partial air pressure at another part of the air mattress in contact with the body and the combined force of the surface tension cause the body to slide down. When the body of the utility model is located at the air mattress enclosure 2, the non-return one-way valve 4 or stop valve is provided between the air mattress enclosure 2 and the air cushion 1, so that the gas in the air mattress enclosure 2 is restricted from flowing to the air mattress, and the air pressure rises sharply. Assume that when the body is not on the inflatable bed surround 2, the air pressure is P1, the temperature is T1, and the volume is V1; and when the body is on the inflatable bed surround 2, the air pressure is P2, the temperature is T2, and the volume is V2. According to the gas state equation theory, P2=T2 / T1*P1*V1 / V2. If the two states are regarded as isothermal changes (T1=T2), the change of P2 is inversely proportional to the change of V2, that is, when the inflatable bed surround 2 is compressed, the air pressure rises, and the smaller V2 is, the higher P2 is. In fact, because V1 is small, the partial derivative of P2 with respect to V2 is relatively large, and P2 increases sharply as V2 decreases. Therefore, the thickness of the edge of the inflatable mattress can be prevented from becoming excessively thin, the surface tension and air pressure supporting force of the inflatable mattress can be maintained, and the collapse of the inflatable mattress can be prevented.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
