Technical Field
[0001] This utility model relates to the field of mattress technology, and in particular to a combined inflatable foam mattress. Background Technology
[0002] Inflatable foam mattresses have air chambers inside, which provide support and elasticity through inflation. This better distributes pressure, making the mattress less prone to deformation during use, while also enhancing its load-bearing capacity. This allows the mattress to maintain a certain degree of firmness while remaining soft, making it suitable for people with different sleeping habits.
[0003] Chinese Patent Publication No. CN217039486U discloses an inflatable mattress, including a mattress body. The mattress body contains a sponge layer, a waterproof layer, a heating layer, and a covering layer. The covering layer and the waterproof layer are wrapped around the sponge layer. Inside the sponge layer is a layer of sponge with the same cross-sectional area as the mattress body. The sponge has a first longitudinal hole, a second longitudinal hole, a first transverse hole, and a second transverse hole. By providing a connector along the upper edge of the waterproof layer, two inflatable mattresses can be connected together via snap fasteners when needed. The inclusion of a layer of sponge with the same cross-sectional area as the mattress body, and the presence of the first longitudinal hole, second longitudinal hole, first transverse hole, and second transverse hole, reduces the weight of the inflatable mattress, making it lightweight and compact, and easy to move and carry. It has the advantages of being lightweight, easy to use, and having a simple structure.
[0004] The aforementioned technology connects adjacent air mattresses via snap fasteners. During installation, the snap fasteners need to be locked one pair at a time, and each air mattress needs to be inflated individually. The disassembly and assembly process is cumbersome, time-consuming, and labor-intensive. Therefore, this utility model discloses a modular air sponge mattress to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a modular inflatable foam mattress to solve the problems mentioned in the background art, which require locking the male and female buckles one by one during the installation and assembly of traditional modular foam mattresses, and each inflatable mattress needs to be inflated separately, making the disassembly and assembly steps cumbersome, complicated, time-consuming and labor-intensive.
[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a combined inflatable sponge mattress, comprising a sponge mattress cover, wherein multiple sponge mattress covers are arranged side by side, an air valve is fixedly embedded on the side of the first end of the sponge mattress cover, multiple elastic components are installed between the upper and lower inner walls of the sponge mattress cover, and adjacent sponge mattress covers are connected by an inflation locking component.
[0007] The inflatable locking assembly includes a female buckle and a female buckle, which are respectively fixedly embedded on the adjacent sides of the two sponge pad covers. The female buckle has an adapter groove on the side facing the female buckle. Both sides of the female buckle have annular locking grooves. Both sides of the adapter groove and on the outer wall of the female buckle have guide grooves. An air-locking piston is provided in each of the guide grooves. A locking rod is fixedly embedded in the middle of each air-locking piston. A second spring is fixedly connected to the outer side of the locking rod and between the air-locking piston and the inner end wall of the adapter groove. The end of the locking rod away from the air-locking piston extends through the female buckle into the locking groove.
[0008] As a further embodiment of this utility model, a pressure boosting tube is fixedly embedded in the middle of the adapter groove, and a connecting channel is opened in the middle of the sub-buckle, the connecting channel being adapted to the pressure boosting tube.
[0009] As a further embodiment of this utility model, the outer wall of the middle part of the air-sealing piston is provided with an outer concave ring, and an outer sealing ring is sleeved inside the outer concave ring.
[0010] As a further embodiment of this utility model, a concave ring is provided on the inner peripheral wall of the connecting channel, and an inner sealing ring is embedded in the concave ring, with the inner sealing ring being sleeved on the outside of the booster pipe.
[0011] As a further embodiment of this utility model, the end of the booster tube away from the adapter groove is shaped like a shuttle, and through holes are provided on both sides of the shuttle-shaped structure.
[0012] As a further embodiment of this utility model, the elastic component includes positioning platforms fixed on the upper and lower inner walls of the outer cover of the sponge pad, and circular positioning columns are fixedly connected to the adjacent sides of the two positioning platforms. A first spring is sleeved on the outer side of the circular positioning column and located between the two positioning platforms.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model discloses a combined inflatable foam mattress, in which multiple foam pad covers are arranged and aligned in sequence, with snap fasteners embedded in the fitting slots and pressurizing tubes embedded in the connecting channels. Users only need to inflate the first foam pad cover through a valve, and the gas can be transferred to the other foam pad covers through the pressurizing tubes, thus achieving simultaneous inflation of multiple foam pad covers. Users can adjust the air pressure according to their own comfort needs to obtain the ideal mattress elasticity.
[0015] This utility model discloses a modular inflatable foam mattress. During inflation, as the air pressure inside the foam pad cover increases, the air-closing piston slides along the guide groove under the action of the air pressure difference. The locking rod is then inserted into the locking groove, preventing two adjacent foam pad covers from detaching. This ensures that the mattress will not loosen or separate due to accidents during use. Conversely, when the air valve is opened, as the air pressure inside the foam pad cover decreases, the second spring returns to its original position, which can drive the locking rod to be pulled out of the locking groove, thereby realizing the separation of multiple foam pad covers. This facilitates the handling and storage of the foam mattress and makes the assembly and disassembly of the foam mattress quick and easy. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments.
[0023] Please see Figure 1-4 This utility model provides a combined inflatable sponge mattress, including a sponge mattress cover 1. The sponge mattress cover 1 is usually a rectangular air bladder structure. Its main body is an air bladder structure, and high-density sponge or memory foam is attached to the outside of the main body. It has the characteristics of being soft, elastic and having strong sealing.
[0024] Furthermore, multiple sponge pad covers 1 are arranged side by side, and a valve 2 is fixedly embedded on the side of the first end of the sponge pad cover 1;
[0025] Specifically, through the valve 2, the user can use an air pump or a manual inflation device to inflate the outer cover 1 of the first end of the foam mattress, so that the foam mattress reaches the required firmness and elasticity. After inflation, the valve 2 can automatically close, thereby preventing the foam mattress from deflating.
[0026] Furthermore, a plurality of elastic components 3 are installed between the upper and lower inner walls of the sponge pad cover 1. Each elastic component 3 includes a positioning platform 31 fixedly on the upper and lower inner walls of the sponge pad cover 1. A circular positioning post 32 is fixedly connected to the adjacent sides of the two positioning platforms 31. A first spring 33 is sleeved on the outer side of the circular positioning post 32 and located between the two positioning platforms 31.
[0027] Specifically, the first spring 33, through its elastic deformation, can provide elasticity and support to the mattress, so that when the mattress is compressed, the spring absorbs the impact energy and rebounds quickly after the pressure is released. The cushioning efficiency is significantly improved compared to the traditional foam layer. The circular positioning post 32 connects the two positioning platforms 31 and provides support and guidance for the first spring 33.
[0028] Furthermore, adjacent sponge pad covers 1 are connected by an inflatable locking assembly 4. The inflatable locking assembly 4 includes a female buckle 41 and a female buckle 42 respectively fixedly embedded on the adjacent sides of the two sponge pad covers 1. The female buckle 41 has an adapter groove 411 on the side facing the female buckle 42. Both sides of the female buckle 42 have annular locking grooves 421. Both sides of the adapter groove 411 and on the outer wall of the female buckle 41 have guide grooves 412. Each guide groove 412 is provided with an air-sealing piston 413. A locking rod 414 is fixedly embedded in the middle of each air-sealing piston 413. A second spring 415 is fixedly connected to the outer side of the locking rod 414 and between the air-sealing piston 413 and the inner end wall of the adapter groove 411. The end of the locking rod 414 away from the air-sealing piston 413 extends through the female buckle 41 into the locking groove 421.
[0029] Specifically, during inflation, as the air pressure inside the foam pad cover 1 increases, the air-closing piston 413 slides along the guide groove 412 under the action of the air pressure difference, and the locking rod 414 is inserted into the locking groove 421, so that two adjacent foam pad covers 1 will not separate. This allows for the synchronous inflation combination of the foam mattress and adjustment of the elasticity and stiffness of the foam mattress. Conversely, when it is necessary to disassemble the foam mattress, simply open the valve 2 to release the gas inside the foam mattress. As the air pressure inside the foam pad cover 1 decreases, the second spring 415 returns to its original position, which can drive the locking rod 414 to be pulled out of the locking groove 421, thereby realizing the separation of multiple foam pad covers 1, which facilitates the handling of the foam mattress.
[0030] Furthermore, a pressure boosting tube 416 is fixedly embedded in the middle of the adapter groove 411, and a connecting channel 422 is opened in the middle of the sub-buckle 42, the connecting channel 422 being adapted to the pressure boosting tube 416;
[0031] Specifically, when adjacent sponge pad covers 1 need to be connected, the male buckle 42 will be inserted into the adapter groove 411 of the female buckle 41, which can ensure that the adjacent sponge pad covers 1 can be kept in the same plane. At the same time, the pressure tube 416 will be inserted into the connecting channel 422, so that the adjacent sponge pad covers 1 can be connected to each other.
[0032] Furthermore, the outer wall of the middle part of the air-sealing piston 413 is provided with an outer concave ring 4131, and an outer sealing ring 4132 is sleeved inside the outer concave ring 4131.
[0033] Specifically, the outer concave ring 4131 is designed to fix the outer sealing ring 4132, ensuring its stable installation on the outer wall of the air-sealing piston 413 and preventing the outer sealing ring 4132 from shifting or falling off during use. The main function of the outer sealing ring 4132 is to prevent gas from leaking from the gap between the air-sealing piston 413 and the inner wall of the guide groove 412. By tightly fitting the outer wall of the air-sealing piston 413, the outer sealing ring 4132 can effectively prevent gas from leaking from the side during the sliding process of the air-sealing piston 413, thereby improving airtightness.
[0034] Furthermore, a concave ring 4221 is provided on the inner peripheral wall of the connecting channel 422, and an inner sealing ring 4222 is embedded in the concave ring 4221. The inner sealing ring 4222 is sleeved on the outside of the pressure boosting pipe 416.
[0035] Specifically, the concave ring 4221 is designed to fix the inner sealing ring 4222, ensuring its stable installation within the connecting channel 422 and preventing the inner sealing ring 4222 from shifting or falling off during use. The main function of the inner sealing ring 4222 is to prevent gas from leaking from the gap between the connecting channel 422 and the booster pipe 416. By clamping the inner sealing ring 4222 onto the outside of the booster pipe 416, the inner sealing ring 4222 can tightly fit the surface of the booster pipe 416, ensuring that gas can only flow through the through hole 4161 of the booster pipe 416.
[0036] Furthermore, the end of the booster tube 416 away from the adapter groove 411 has a spindle-shaped structure, and through holes 4161 are provided on both sides of the spindle-shaped structure.
[0037] Specifically, one end of the spindle-shaped structure is pointed, which facilitates the insertion of the pressurizing tube 416 into the connecting channel 422 of the buckle 42. The function of the through hole 4161 is to allow gas to flow between the inside and outside of the pressurizing tube 416. When gas is filled into the first end sponge pad cover 1 through the valve 2, the gas can enter other sponge pad covers 1 through the through hole 4161 of the pressurizing tube 416, thereby realizing the synchronous inflation of multiple sponge pad covers 1.
[0038] Working principle: In use, multiple sponge pad covers 1 are arranged and aligned in sequence, and the buckle 42 is inserted into the adapter groove 411. The pressurization pipe 416 is inserted into the connecting channel 422. Air is injected into the first sponge pad cover 1 through the valve 2. The pressurization pipe 416 connects all the sponge pad covers 1, allowing the air pressure inside each sponge pad cover 1 to continuously increase. As the air pressure inside the sponge pad cover 1 increases, the air-closing piston 413 slides along the guide groove 412 under the action of the air pressure difference, and the locking rod... 414 can be inserted into the locking groove 421, so that the two adjacent foam pad covers 1 will not detach, which can realize the synchronous inflation combination of the foam mattress and adjust the elasticity and stiffness of the foam mattress. Conversely, when it is necessary to disassemble the foam mattress, simply open the valve 2 to release the gas inside the foam mattress. As the air pressure inside the foam pad cover 1 decreases, the second spring 415 returns to its original position, which can drive the locking rod 414 to be pulled out of the locking groove 421, thereby realizing the separation of multiple foam pad covers 1, which can facilitate the handling of the foam mattress.
