Description

Technical Field

[0001] The utility model relates to the technical field of inflatable mattresses, in particular to a self-inflating and press-inflating mattress. Background Art

[0002] Existing inflatable mattresses mainly consist of a fabric, air chambers, drawstrings, an inflation nozzle, and a deflation nozzle. The air chambers are used to divide the load-bearing areas of the air cushion, such as dividing the load-bearing areas of the pillow, body, and foot of the air cushion; drawstrings are used to limit the expansion range of the left-right width and up-down thickness of the mattress; the fabric is used to limit the outer shape. Another inflator is provided to inflate the inflation nozzle to expand the air chambers. The left-right width and up-down thickness of the mattress are restricted by the drawstrings, and it can be inflated into various shapes such as a seat cushion, a mattress, a mattress with a pillow, a seat cushion with a rectangular shape as a whole, and an automotive mattress customized according to the interior space of a vehicle.

[0003] The industry has tried to combine a press-inflating component with the air chambers so that there is no need to separately provide an inflator to inflate the seat cushion (mattress). For example, CN209677953U discloses a press-inflating seat cushion (mattress). The specification records: This embodiment provides a press-inflating seat cushion, including a body 1 made of rubber, specifically made of TPU rubber. A plurality of airbag cavities 2 are formed on the body 1, and each of the airbag cavities 2 is communicated through a channel 4. An inflation airbag 3 is further provided on the body 1. One end of the inflation airbag 3 is placed outside the main body 1, and the other end is placed inside the airbag cavity 2. The multiple airbag cavities 2 communicate with each other, so that it is not necessary to provide multiple inflation ends to achieve overall inflation; moreover, an inflation airbag 3 is integrated in one of the airbag cavities 2, so that direct press-inflation can be carried out during use without connecting other inflation devices. Therefore, it is convenient to carry outdoors, convenient for users to fold and use accordingly, and this embodiment can also be placed inside some products for use, such as inside a blanket, an automotive seat cushion, a mattress, and other products with cavities. Although CN209677953U does not need to additionally configure an inflator, and an inflation airbag 3 is integrated in one of the airbag cavities 2, only this inflation airbag 3 is used to inflate the entire inflatable seat cushion (mattress). The volume ratio of the inflation airbag to the entire seat cushion (mattress) is too small, and the press-inflation molding will be very long, affecting the experience effect.

[0004] The following problems exist in existing seat cushions or mattresses and need to be solved:

[0005] 1). An external inflator or a separately provided press-inflating device. The external inflator has a small power, a slow inflation speed, and it is difficult to fully inflate. A high-power inflator is heavy and inconvenient to carry; when using a press-inflating device for inflation, the press-inflation molding will be very long, affecting the experience effect.

[0006] 2). The drawstring, as an inflatable auxiliary forming component, is often pulled by force during long-term use. It is generally sewn into the fabric, prone to thread breakage and damage, and is also prone to cracking and damage itself. Once the drawstring is damaged, it will affect the shape of the air cushion, such as a protrusion or other deformation in a certain area compared to the adjacent area.

[0007] 3). The strength of the drawstring is limited. Without inflation, it simply cannot automatically support the preliminary forming and must be inflated to form.

[0008] In view of the deficiencies of the prior art, it is of great significance to provide an inflatable mattress that can automatically inflate and form, further quickly replenish air, is lightweight and easy to store. Summary of the Utility Model

[0009] The purpose of the present utility model is to provide a self-inflating and pressing inflatable mattress to avoid the deficiencies of the prior art.

[0010] The above object of the present utility model is achieved by the following technical means:

[0011] A self-inflating and pressing inflatable mattress, comprising: a sealed air chamber 1 formed by combining an upper fabric 11 and a lower fabric 12. The sealed air chamber 1 is provided with more than one air inlet valve 2 and an air release valve 3. A high resilience layer 4 with a reduced specific gravity is provided inside the sealed air chamber 1;

[0012] The inflatable mattress is further provided with a pressing inflating member 5. The pressing inflating member 5 has a pressing and rebounding airbag 51, a one-way air replenishing valve 52, and a one-way inflating valve 53. The one-way inflating valve 53 communicates with the sealed air chamber 1.

[0013] Optionally, the pressing and rebounding airbag 51 of the pressing inflating member 5 is arranged inside the sealed air chamber 1, and the one-way air replenishing valve 52 extends outside the sealed air chamber 1.

[0014] Optionally, the pressing and rebounding airbag 51 of the pressing inflating member 5 protrudes from the sealed air chamber 1.

[0015] Optionally, the pressing and rebounding airbag 51 of the pressing inflating member 5 is arranged outside the sealed air chamber 1, and the one-way inflating valve 53 communicates with the sealed air chamber 1 through one of the air inlet valves 2.

[0016] Optionally, the upper fabric 11 is provided with a recess matching the pressing and rebounding airbag 51. The recess is provided with an air inlet. The pressing and rebounding airbag 51 is arranged in the recess, and the one-way inflating valve 53 communicates with the sealed air chamber 1 through the air inlet.

[0017] Preferably, the air inlet valve 2 and the air release valve 3 are the same air valve.

[0018] Preferably, the air inlet valve 2 and the air release valve 3 are separately arranged air valves.

[0019] Preferably, the intake valve 2 is a one-way intake valve.

[0020] Optionally, the high-resilience layer 4 is a polymer spinning material pad 41. The polymer spinning material pad 41 reduces its specific gravity by thinning the spun fibers and / or increases voids by reducing the spinning density to lower the specific gravity.

[0021] Optionally, the high-resilience layer 4 is a sponge PU material pad 42. The sponge PU material pad 42 reduces its specific gravity by punching large areas on the front and / or side surfaces of the material pad.

[0022] Advantages of adopting the above technical solutions:

[0023] 1). For the high-resilience layer described in this application, it is mainly considered that after reducing the specific gravity, it can basically support the upper fabric to make the air chamber bulge and inflate automatically, without considering human pressure. Although the specific gravity of the high-resilience layer of this inflatable mattress is reduced, it can still be automatically inflated and formed; after deflation, the quality of the inflatable mattress is mainly determined by the fabric and the high-resilience layer. Considering that the specific gravity of the high-resilience layer is reduced, the quality of this inflatable mattress is very light after deflation, and the high-resilience layer with reduced specific gravity is easier to compress and convenient for storage.

[0024] 2). In this application, when the specific gravity of the high-resilience layer is reduced to 30%-70%, the inflatable mattress can still recover to 80%-60% of the saturated state, and it only needs to be press-supplemented with air by 20%-40% to fully inflate the inflatable mattress, saving time and quickly supplementing air.

[0025] 3). Compared with traditional inflatable mattresses, this inflatable mattress uses a high-resilience layer to replace the traditional drawstring. The high-resilience layer is not sewn to the fabric, is not easily damaged and does not cause the inflatable mattress to deform. The processing is simpler. The high-resilience layer can not only support the automatic inflation of the inflatable mattress but also assist in the formation of the inflatable mattress, achieving unexpected technical effects.

[0026] 4). This inflatable mattress is a lightweight household item. Due to its characteristics of being able to automatically restore the mattress shape, convenient and fast air replenishment, easy storage, and portability, it can be used as a temporary mattress for cars, camping, and outdoor activities, etc., and can also be used as an emergency mattress for military, schools, hospitals, etc. Of course, this inflatable mattress can also serve as a seat cushion and has a wide range of uses.

Specific implementation manners

[0040] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0041] Embodiment 1.

[0042] As Figure 1-10 shown, there is provided a self - filling and pressing inflatable mattress, including: a sealed air chamber 1 formed by combining an upper fabric 11 and a lower fabric 12, the sealed air chamber 1 being provided with more than one air inlet valve 2 and air outlet valve 3, and a high resilience layer 4 for reducing the specific gravity being provided inside the sealed air chamber 1;

[0043] The inflatable mattress is also provided with a press-type inflating member 5. The press-type inflating member 5 has a press-and-rebound airbag 51, a one-way air supplement valve 52, and a one-way inflation valve 53. The one-way inflation valve 53 is communicated with the sealed air chamber 1.

[0044] Generally, the upper fabric 11 and the lower fabric 12 are selected from TPU fabrics with cloth or PVC fabrics with cloth. Or other soft materials that are wear-resistant, comfortable, skin-friendly, and have good sealing performance can be selected.

[0045] Usage state: Open the air inlet valve 2, and unfold the inflatable mattress in the storage state at the usage site. When the high-resilience layer 4 resumes a certain supporting strength and propping up the sealed air chamber 1, gas is inhaled from the air inlet valve 2 to automatically inflate the sealed air chamber 1. As Figure 1 and Figure 7 shown, after reaching a certain saturation state, the inflatable mattress is automatically formed. Continue to press for air supplement or directly use the inflatable mattress. If directly using the inflatable mattress, then close the air inlet valve 2;

[0046] Press for air supplement: Press the press-and-rebound airbag 51. The gas in the rebound airbag 51 is supplemented to the sealed air chamber 1 through the one-way inflation valve 53. When the rebound airbag 51 resumes bulging, gas is inhaled from the one-way air supplement valve 52 to inflate the rebound airbag 51. In this way, the sealed air chamber 1 is continuously supplemented with air; As Figure 8 shown in the fully inflated state of the inflatable mattress; after air supplement, close the air inlet valve 2.

[0047] Storage state: As Figure 9 shown, open the air release valve 3, and fold the inflatable mattress in the usage state according to the storage habit. During the folding process, manually press the sealed air chamber 1 to compress the high-resilience layer 4, so that the gas in the sealed air chamber 1 is automatically released from the air release valve 3.

[0048] For the high-resilience layer described in this application, it is mainly considered that after reducing the specific gravity, it can basically support the upper fabric to make the air chamber bulge and inflate automatically, without considering the human body pressure. Although the specific gravity of the high-resilience layer of this inflatable mattress is reduced, it can still be automatically inflated and formed; the quality of the inflatable mattress after deflation is mainly determined by the fabric and the high-resilience layer. Considering that the specific gravity of the high-resilience layer is reduced, the quality of this inflatable mattress after deflation is very light, and the high-resilience layer with reduced specific gravity is easier to be compressed and convenient for storage.

[0049] Of course, the size of the reduction in the specific gravity of the high-resilience layer 4 is inversely proportional to the saturation state of the automatic formation of the inflatable mattress, but it can still resume a large proportion of the saturation state when there is no body weight pressure. For details, please refer to the following inflatable mattress saturation state test table.

[0050]

[0051] The above inflatable mattress saturation state test form uses the high resilience layer that can restore more than 95% saturation as the standard specific gravity for the standard reference object of the high resilience layer.

[0052] In this application, when the specific gravity of the high resilience layer is reduced to 30%-70%, the inflatable mattress can still restore the saturation state to 80%-60%. By pressing to supplement air by 20%-40%, the inflatable mattress can be fully inflated, saving time and quickly supplementing air.

[0053] Secondly, compared with the traditional inflatable mattress, this inflatable mattress uses a high resilience layer to replace the traditional drawstring. The high resilience layer is not sewn to the fabric, is not easily damaged and does not cause the inflatable mattress to deform. The processing is simpler. The high resilience layer can not only support the automatic inflation of the inflatable mattress but also assist in the shaping of the inflatable mattress, achieving unexpected technical effects.

[0054] This inflatable mattress is a portable household item. Due to its characteristics such as being able to automatically restore the mattress shape, convenient and fast air replenishment, easy storage, and portability, it can be used as a temporary mattress for cars, camping, and outdoor activities, etc., and can also be used as an emergency mattress for military, schools, hospitals, etc. Of course, this inflatable mattress can also serve as a seat cushion and has a wide range of uses.

[0055] Embodiment 2. This embodiment is one of the alternative embodiments of the press-type inflating member 5. As Figure 1 and Figure 4-7 shown, the press-and-rebound airbag 51 of the press-type inflating member 5 is arranged in the sealed air chamber 1, and the one-way air replenishing valve 52 extends out of the sealed air chamber 1.

[0056] Embodiment 3. This embodiment is the second alternative embodiment of the press-type inflating member 5. As Figure 1 shown, the press-and-rebound airbag 51 of the press-type inflating member 5 protrudes from the sealed air chamber 1.

[0057] Embodiment 4. This embodiment is the third alternative embodiment of the press-type inflating member 5, not shown in the figure. The press-and-rebound airbag 51 of the press-type inflating member 5 is arranged outside the sealed air chamber 1, and the one-way inflation valve 53 communicates with the sealed air chamber 1 through one of the intake valves 2. In this embodiment, the press-type inflating member 5 can be independently carried and can inflate other inflatable items including this inflatable mattress. When in use, connect the one-way inflation valve 53 to one of the intake valves 2.

[0058] Embodiment 5. This embodiment is the fourth alternative embodiment of the press-type inflating member 5, not shown in the figure. The upper fabric 11 is provided with a recess matching the press-and-rebound airbag 51. The recess is provided with an air inlet. The press-and-rebound airbag 51 is arranged in the recess, and the one-way inflation valve 53 communicates with the sealed air chamber 1 through the air inlet.

[0059] Embodiment 6. In this embodiment, the same valve is used for inflation and deflation. AsFigure 10-12 As shown, the intake valve 2 and the exhaust valve 3 are the same valve, which makes processing simpler. As Figure 12 shown, when this valve is opened, the inflated mattress in the stored state is unfolded on the usage site. During the process that the high-resilience layer 4 restores a certain supporting strength to prop up the sealed air chamber 1, gas is inhaled from this valve to automatically inflate the sealed air chamber 1. After reaching a certain saturation state, the inflated mattress is automatically formed. If continuing to press for supplementary inflation or directly using the inflated mattress, then as Figure 11 shown, close this valve; when deflation is needed, open this valve.

[0060] Embodiment 7. In this embodiment, the inflation valve and the deflation valve are separately arranged. As Figure 1 shown, the intake valve 2 and the exhaust valve 3 are separately arranged valves.

[0061] Embodiment 8. As Figure 1 、 4 -6 shown, the intake valve 2 is a one-way intake valve. The one-way intake valve is separately arranged from the exhaust valve. The one-way intake valve only intakes air and does not exhaust air. When the inflated mattress in the stored state is unfolded on the usage site, during the process that the high-resilience layer 4 restores a certain supporting strength to prop up the sealed air chamber 1, gas is inhaled from the one-way intake valve to automatically inflate the sealed air chamber 1. After reaching a certain saturation state, the inflated mattress is automatically formed. If continuing to press for supplementary inflation or directly using the inflated mattress; when deflation is needed, open the exhaust valve.

[0062] Embodiment 9. This embodiment shows one type of high-resilience layer. As Figure 2 、 6 shown, the high-resilience layer 4 is a polymer spunlace material pad 41. The polymer spunlace material pad 41 reduces its specific gravity by thinning the spunlace, and / or increases voids by reducing the spunlace density to reduce the specific gravity. The spunlace with reduced specific gravity is easier to be flattened for folding compared with the spunlace or spring of conventional thickness, and also has a certain supporting strength.

[0063] Embodiment 10. This embodiment shows another type of high-resilience layer. As Figure 3-5 shown, the high-resilience layer 4 is a sponge PU material pad 42. The sponge PU material pad 42 reduces its specific gravity by punching large areas on the front and / or side surfaces of the material pad. As Figure 3 shown, the sponge PU material pad 42 reduces its specific gravity by punching large areas on the front surface of the material pad. As Figure 4 shown, the sponge PU material pad 42 reduces its specific gravity by punching large areas on the side surface of the material pad. Of course, the sponge PU material pad 42 can maximize the reduction of specific gravity by punching large areas on both the front and side surfaces of the material pad.

[0064] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
