Description

[Technical field]

[0001] The present invention relates to the field of mattresses, and in particular to ultra-thin mattresses. [Background technology]

[0002] In recent years, breathable mattresses have gradually become more popular among users, and have an air passage layer pre-installed inside and an air supply device attached to the outside, which introduces outside air into the air passage, forming a ventilation airflow in the mattress and realizing functions such as heating, cooling, and dust mite extermination.

[0003] However, due to the design of the air passage layer, the user is likely to feel a sudden sensation when lying down on the mattress, so in the prior art, a cushion layer made of a material such as sponge is laid on top of the air passage layer to improve sleeping comfort.

[0004] The thickness of the breathable mattress increases significantly compared to that of a normal mattress due to the increase in the number of air passage layers and cushion layers, etc. Furthermore, a breathable mattress capable of realizing a heating function needs to have an additional heat shielding layer in the air passage to prevent burns to the user, which makes the breathable mattress thicker. Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide an ultra-thin breathable mattress that is thin and does not affect the comfort of sleeping on it. [Means for solving the problem]

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: The ultra-thin mattress includes a ventilation layer having a plurality of air holes and a cushion body having an upper surface, the cushion body having a cutout opening used for installing a housing, the housing including a cushion layer having a cavity for accommodating an air supply device, an attachment opening whose opening faces the outside of the mattress, and at least one air outlet. The cushion body further has a first passage recessed from an upper surface of the cushion body. A main air duct is attached within the first passage. The main air duct is connected to an air outlet of the housing and receives an airflow from a ventilation device. The cushion body further has a second passage recessed from the upper surface of the cushion body. A ventilation branch pipe is attached within the second passage. The ventilation branch pipe receives the airflow from the main ventilation pipe and releases the airflow through an exhaust hole of the ventilation branch pipe to the plurality of ventilation holes, thereby supplying the airflow to the supine portion of the ventilation layer. The ventilation layer is disposed above the cushion layer. The distances from the bottom surface of the ventilation layer to the top surface of the ventilation main pipe, the bottom surface of the ventilation layer to the top surface of the ventilation branch pipe, and the bottom surface of the ventilation layer to the top surface of the cushion body are approximately equal, and the ventilation layer fits smoothly onto the cushion layer. The ventilation main pipe is made of a heat insulating material and / or has a top heat insulating chamber. The housing further includes an air passage. The air passage has one end communicating with the air outlet of the housing and the other end communicating with a ventilation connection port or joint of the housing, and receives the airflow from the air supply device. In comparison with the prior art, in the present invention, the ventilation main pipe and ventilation branch pipes are installed in the first and second passages, so that the airflow from the ventilation device passes through the ventilation main pipe and ventilation branch pipe and escapes to the ventilation layer through the exhaust hole, thereby realizing ventilation of the mattress. Since the ventilation main pipe and ventilation branch pipe are installed in the first and second passages recessed from the upper surface of the cushion body, the thickness of the mattress of the present invention can be reduced to a certain extent.

[0007] Furthermore, the vent main is made of a heat insulating material and / or has a top heat insulating chamber, so that the vent main of the present invention fits directly and smoothly onto the ventilation layer, preventing burns to the user. Therefore, in the mattress of the present invention, no heat insulating layer is installed on top of the vent main, further reducing the thickness of the mattress.

[0008] Furthermore, the distance from the upper surface of the ventilation branch pipe to the bottom surface of the ventilation layer and the distance from the upper surface of the cushion body to the bottom surface of the ventilation layer are approximately equal, and the ventilation layer fits smoothly onto the cushion layer. Therefore, when a user lies down on the ventilation layer, he or she is supported simultaneously by the upper surface of the cushion body and the upper surface of the ventilation branch pipe, effectively ensuring a comfortable sleep.

[0009] In one preferred embodiment, the first passage extends along the width direction of the cushion body and includes a bottom wall, an outer wall, and an inner wall. One side of the cushion body adjacent to the inner wall is a reclining portion, and one side of the cushion body adjacent to the outer wall is a heat insulating portion. The air main is attached within the first passage. The outer surface of the air main is received by the heat insulating portion of the cushion body by contacting the outer wall of the first passage.

[0010] In a preferred embodiment, the ventilation main pipe includes a gas passage and a ventilation connection port or joint opened on the inner surface. Airflow from the ventilation device flows into the ventilation branch pipe from the ventilation connection port or joint via the gas passage. The ventilation main pipe further includes a groove recessed from the upper surface of the ventilation main pipe and a top plate provided at an opening above the groove. The top plate is connected to the groove to form a top heat shielding chamber, or divides the groove into two top heat shielding chambers, upper and lower.

[0011] In one preferred embodiment, the heat insulating material is a resin.

[0012] In one preferred embodiment, the ventilation branch is a single pipe, and the size of the second passage corresponds to the size of the single pipe.

[0013] Further, the size of the ventilation branch pipe gradually decreases from the intake end along the longitudinal direction of the ventilation branch pipe, and / or the size of the second passage gradually decreases from its end along the longitudinal direction of the second passage.

[0014] Furthermore, the number of exhaust holes provided in the ventilation branch pipe gradually increases from the intake end along the longitudinal direction of the ventilation branch pipe.

[0015] In one preferred embodiment, the outlet is airtightly connected to the inlet of the air main, the cross section of the outlet corresponding to the cross section of the inlet.

[0016] In one preferred embodiment, the second passage extends along the longitudinal direction of the cushion body and is located in the supine portion of the cushion body. An end of the second passage is located on the inner wall of the first passage. The inner surface of the main ventilation pipe contacts the inner wall of the first passage. A ventilation connection or fitting is provided on the inner surface of the main ventilation pipe. The ventilation connection or fitting is located opposite the end of the second passage and / or is located on the same horizontal plane as the branch ventilation pipe attached to the second passage.

[0017] In one preferred embodiment, the cushion body further includes a third passage recessed from an upper surface of the cushion body, and a ventilation branch pipe is attached within the third passage, the ventilation branch pipe receives the airflow from the air passage, and releases the airflow to the plurality of ventilation holes via an exhaust hole of the ventilation branch pipe.

[0020] In order to better describe the present invention, the present invention will now be described in more detail with reference to the drawings.

[0021] As shown in Figures 1 to 8, the present invention provides an ultra-thin mattress 1. The ultra-thin mattress includes a base material 10, a cushion layer 20 disposed on the base material, and a ventilation layer 30 disposed on the cushion layer. The ventilation layer 30 has a number of ventilation holes, which are not shown unless they affect the understanding of the present invention.

[0022] The cushion layer 20 includes a cushion body 200 having an upper surface 210. The cushion body has a cutout 220, a first passageway 230 recessed from the upper surface of the cushion body, and a second passageway 240 recessed from the upper surface of the cushion body.

[0023] The cutout is used to install the housing 40. The housing is used to attach the air supply device. Specifically, after the cushion layer 20 is placed on the substrate 10, a groove is formed at the cutout and the upper surface of the substrate. The groove has an upward opening and an opening facing the outside of the mattress. The housing is attached by inserting the housing into the groove through the upward opening or the opening facing the outside of the mattress. The housing 40 has a cavity 41 for accommodating the air supply device and an attachment opening 42 whose opening direction faces the outside of the mattress. The air supply device can be attached into the cavity or removed from the cavity through the attachment opening.

[0024] An air main 50 is mounted within the first passageway 230. The air main is connected to the housing and receives airflow from a fan. Specifically, when the fan is operating, air flows from outside the mattress through the attachment port into the fan and is sent into the air main.

[0025] A ventilation branch pipe (not shown) is attached in the second passage 240. The ventilation branch pipe receives the airflow from the main ventilation pipe, and releases the airflow to the plurality of ventilation holes via the exhaust hole of the ventilation branch pipe, thereby supplying the airflow to the supine portion of the ventilation layer. Specifically, a plurality of ventilation connection ports or joints 51 are opened in the main ventilation pipe. The cushion layer has a plurality of second passages 240 recessed from the upper surface of the cushion body. A ventilation branch pipe is attached in each second passage 240. One ventilation branch pipe corresponds to one ventilation connection port or joint.

[0026] In the present invention, by installing the ventilation main duct 50 and ventilation branch ducts in the first passage 230 and the second passage 240, it is possible for the airflow from the ventilation device to escape through the exhaust hole to the ventilation layer via the ventilation main duct and ventilation branch duct, thereby realizing ventilation of the mattress. Since the ventilation main duct and ventilation branch ducts are installed in the first passage and the second passage recessed from the upper surface of the cushion body, the thickness of the mattress of the present invention is made thinner to a certain extent.

[0027] In order to further reduce the thickness of the mattress, the ventilation main 50 of the present invention is made of a heat insulating material and / or has a top heat insulating chamber 52. Even if the ventilation main 50 of the present invention fits directly and smoothly into the ventilation layer, it is possible to prevent burns to the user. Therefore, in the mattress of the present invention, no heat insulating layer is installed on the top of the ventilation main 50, thereby further reducing the thickness of the mattress. Preferably, the heat insulating material is a resin.

[0028] Furthermore, since there is no need to install a heat insulating layer on the top of the main ventilation duct 50, when the ventilation layer is disposed above the cushion layer 20, the distance from the bottom surface of the ventilation layer 30 to the top surface 501 of the main ventilation duct, the distance from the bottom surface 502 of the ventilation layer to the top surface 501 of the branch ventilation duct, and the distance from the bottom surface of the ventilation layer 30 to the top surface 210 of the cushion body are approximately equal, and the ventilation layer 30 fits smoothly onto the cushion layer 20. When a user lies down on the ventilation layer 30, he or she can be supported simultaneously by the top surface 210 of the cushion body and the top surface of the branch ventilation duct, effectively ensuring comfort.

[0029] The cushion body, main ventilation pipe 50, branch ventilation pipes and housing 40 of the ultra-thin mattress of the present invention will be described in detail below.

[0030] The cushion body 200 of the present invention has an upper surface 210, a first passageway 230 recessed from the upper surface 210 of the cushion body, and a second passageway 240 recessed from the upper surface 210 of the cushion body. The first passage 230 extends along the width direction of the cushion body 200 and includes a bottom wall 231, an outer wall 232 and an inner wall 233. One side of the cushion body 200 adjacent to the inner wall 233 is a reclining portion 260, and one side of the cushion body 200 adjacent to the outer wall 232 is a heat insulating portion 270.

[0031] The second passage 240 extends along the width direction of the cushion body 20 and is located in the supine portion of the cushion body 20 .

[0032] Preferably, the first passage 230 is divided into a left passage 234 and a right passage 235. The cutout 220 of the cushion body 20 is located between the left passage 234 and the right passage 235.

[0033] The lying portion 260 of the cushion body 20 is divided into a left lying area 261 and a right lying area 262. The left lying area 261 and the right lying area 262 each have a plurality of second passages 240 recessed from the upper surface 210 of the cushion body. The left ventilation main 54 attached to the left passage supplies airflow to the left lying area 261 through a ventilation branch pipe of the left lying area 261. The right ventilation main 55 attached to the right passage supplies airflow to the right lying area 262 through a ventilation branch pipe of the right lying area 262.

[0034] The cushion body 200 further includes a middle lying area 263 located between the left lying area 261 and the right lying area 262. In some specific embodiments, the cushion body 200 further includes a third passage 250 recessed from the upper surface 210 of the cushion body. Specifically, the middle lying area 263 includes a plurality of third passages 250 recessed from the upper surface 210 of the cushion body. A ventilation branch pipe is installed in the third passage 250 of the middle lying area 263.

[0035] The vent main 50 of the present invention includes a gas passageway 53, a vent connection or fitting 51. The vent main 50 includes a top surface 501, a bottom surface 502, an inner surface 504 and an outer surface 503.

[0036] The ventilation main 50 is attached in the first passage 230. The bottom surface 502 contacts the bottom wall 231 of the first passage 230. The outer side surface 503 contacts the outer side wall 232 of the first passage 230 and is received by the heat insulating portion 270 of the cushion body 200. The inner side surface 504 contacts the inner side wall 233 of the first passage 230. The ventilation connection port or joint 51 is opened on the inner side surface 504. Airflow from the ventilation device passes through the gas passage 53 and flows from the ventilation connection port or joint 51 into the ventilation branch pipe.

[0037] The air main 50 further includes a groove 521 recessed from the upper surface 501 of the air main, and a top plate 522 provided at the upper opening of the groove. The top plate is connected to the groove to form a top heat shielding chamber 52. In another embodiment, the top plate is connected to the groove to divide the groove into two top heat shielding chambers, upper and lower. The upper heat shielding chamber 523 has an upward opening, and the lower heat shielding chamber 524 is a partition layer. In addition, the height of the upper heat shielding chamber 523 is lower than the height of the lower heat shielding chamber 524. Preferably, the lower heat shielding chamber further has an opening facing the outside of the mattress.

[0038] After being heated by the air supply device, the air flows into the gas passage 53 of the air main 50 and transfers heat to the outer surface 503 and the upper surface 501 of the air main 50. The outer surface 503 of the air main is received by the heat shielding portion 270 of the cushion body 200, so that burns to the user can be effectively prevented. The upper surface 501 of the air main is separated by the top heat shielding chamber 52, so that burns to the user can be effectively prevented as well. Preferably, in an embodiment using two top heat shielding chambers, one above the other, the heat transferred to the top is first blocked by the lower heat shielding chamber, and a small amount of residual heat is blocked again by the upper heat shielding chamber.

[0039] Preferably, the ventilation main 50 is made of a heat insulating material such as resin, etc. In this case, the heat insulating effect is more excellent.

[0040] Preferably, the air main 50 is partitioned into a left air main 54 and a right air main 55. The left air main 54 and the right air main 55 are located in the left passage 234 and the right passage 235, respectively.

[0041] It is preferable that the main ventilation pipe 50 of the present invention is an independent pipe, and the size of the second passage corresponds to the size of the independent pipe. By installing in this way, the size of the second passage 240 can be effectively reduced, and the sudden feeling when lying down due to the size of the second passage 240 being too large can be suppressed, and the comfort of the mattress of the present invention can be further improved.

[0042] However, because the cross section of the single piping is small, the amount of air flowing into the ventilation branch pipe 50 is small, and after the airflow passes through the long and thin ventilation branch pipe, the amount of airflow that escapes from the mattress is also small. In particular, at one end away from the ventilation main pipe 50 and close to the bed board, the amount of airflow that escapes is smaller, which affects the ventilation effect of the mattress.

[0043] The mattress can be ventilated while ensuring the comfort of the mattress. The housing 40 of the present invention includes at least one air outlet 43. The air outlet is airtightly connected to the air inlet 56 of the air main. Preferably, the embodiment of the present invention has two air outlets 43, one on the left and one on the right, which are airtightly connected to the left air main 54 and the right air main 55, respectively.

[0044] Specifically, the housing 40 has a blow-out plug 44 that can be directly inserted into the connecting end of the ventilation main duct 50. A seal ring 45 is provided around the connecting end of the blow-out plug 44 and the ventilation main duct 50. This can prevent air leakage between the housing 40 and the ventilation main duct 50 at the connecting point, and increases the air flow rate into the ventilation main duct 50.

[0045] Preferably, the cross section of the outlet 43 corresponds to the cross section of the inlet 56, ensuring that the airflow emitted by the air supply device is directed at maximum into the ventilation main 50, thereby increasing the airflow rate.

[0046] Preferably, an end of the second passage 240 is located on the inner wall of the first passage 230. The ventilation connection port or joint 51 is installed opposite to the end of the second passage 240. Preferably, the ventilation connection port or joint 51 is located on the same horizontal plane as the ventilation branch pipe, and the airflow flows in a straight line from the ventilation connection port or joint 51 into the ventilation branch pipe of the second passage, improving ventilation efficiency and increasing the amount of ventilation to the ventilation branch pipe.

[0047] In order to further improve the sleeping comfort of the mattress according to the present invention, the ventilation branch pipe 50 of the present invention is made elongated. Preferably, the size of the second passage 240 gradually decreases from its end along the longitudinal direction of the second passage 240. The size of the second passage 240 at one end close to the bed board is smaller than the size of the second passage 240 at one end close to the foot board. This improves the comfort when the user lies down.

[0048] Furthermore, in order to ensure the airflow rate of the bed board, the number of exhaust holes in the ventilation branch pipe gradually increases from the intake end along the longitudinal direction of the ventilation branch pipe, thereby increasing the outflow airflow rate. Meanwhile, the size of the ventilation branch pipe gradually decreases from the intake end along the longitudinal direction of the ventilation branch pipe, and the inflow speed of the airflow increases toward the rear, thereby increasing the outflow airflow rate.

[0049] An air passage 46 is provided in the housing 40. One end of the air passage 46 communicates with the air outlet 43 of the housing 40, and the other end communicates with a ventilation connection port or joint 47 of the housing. The air passage 46 receives the airflow from the air supply device.

[0050] Specifically, an air duct of the present invention is attached in the third passage 250. The air duct receives the airflow from the air passage and releases the airflow to the plurality of vent holes via an exhaust hole of the air duct.

[0051] Those skilled in the art can make appropriate changes and modifications to the above embodiments based on the disclosure and teachings of the above specification. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also be included in the scope of protection of the claims of the present invention.
