Description

Technical Field

[0001] This utility model relates to massage products, and in particular to a valve core and a massage air cushion. Background Technology

[0002] Currently, the most cost-effective valve cores are generally rubber valve cores. Their main principle is that during inflation, external air pressure expands the valve core, allowing gas to enter the air cushion; when inflation stops, the valve core automatically contracts to prevent gas backflow and ensure stable air pressure. However, this type of valve core has some drawbacks. As it ages, its contraction becomes insufficient, leading to deflation. Furthermore, it requires specific equipment for inflation, which is generally unavailable in ordinary households. Therefore, an inflation device must be purchased along with the valve core, resulting in higher costs and lower inflation efficiency. This is especially true for massage air cushions, which are typically used by young people who need to inflate quickly to achieve arousal and avoid prolonged use that could affect sexual pleasure. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a valve core and a massage air cushion that solve at least one of the above problems.

[0004] A valve core includes a core body and a sealing gasket. The core body has a through-hole forming a vent hole. The sealing gasket is disposed on the vent hole at one end of the core body and is connected to the core body. A first limiting ring is disposed inside the core body, and the inner side of the sealing gasket abuts against the first limiting ring. A second limiting ring is disposed at the other end of the core body, and the outer diameter of the second limiting ring corresponds to the inner diameter of the air outlet of a blower.

[0005] By setting a first limiting ring, during use, the atmospheric pressure difference drives the sealing gasket to abut against the first limiting ring, thereby sealing one end of the vent hole and preventing air leakage.

[0006] By setting a second limiting ring, the air outlet of the hair dryer can be directly attached to the second limiting ring, and then the massage air cushion on the other side of the air hole can be inflated by the hair dryer. The inflation efficiency is higher, and there is no need to use special inflation equipment, which reduces costs. Attached Figure Description

[0022] Please see Figure 1-6 A valve core 10 according to an embodiment of the present invention includes a core body 100 and a sealing gasket 200. The core body 100 has a through-hole 130 formed in the middle. The sealing gasket 200 is disposed on the through-hole 130 at one end of the core body 100 and is connected to the core body 100. A first limiting ring 110 is disposed inside the core body 100, and the inner side of the sealing gasket 200 abuts against the first limiting ring 110.

[0023] The other end of the core 100 is provided with a second limiting ring 120, the outer diameter of which corresponds to the inner diameter of the air outlet of the blower.

[0024] In this embodiment, by setting the first limiting ring 110, during use, the atmospheric pressure difference drives the sealing gasket 200 to abut against the first limiting ring 110 to block one end of the vent 130, thereby preventing air leakage.

[0025] By setting a second limiting ring 120, the air outlet of the hair dryer can be directly attached to the second limiting ring 120, and then the massage air cushion 20 on the other side of the vent 130 can be inflated by the hair dryer. The inflation efficiency is higher, and there is no need to use special inflation equipment, which reduces costs.

[0026] The valve core 10 is installed on the air inlet and outlet of the massage air cushion 20. The sealing gasket 200 is located inside the vent 130 and within the massage air cushion 20. The second limiting ring 120 is located outside the vent 130. When inflation is required, align the air outlet of the blower with the second limiting ring 120 and fasten it. Turn on the blower to start inflation. At this time, the external air pressure lifts the sealing gasket 200 and quickly inflates it through the space opened between the sealing gasket 200 and the first limiting ring 110. After inflation is complete, turn off the blower. At this time, due to the pressure difference between the inside and outside, the sealing gasket 200 will return to the position of abutting against the first limiting ring 110, achieving a sealing effect. When the massage air cushion 20 needs to be stored, simply insert your finger into the vent 130 and open a certain gap between the sealing gasket 200 and the first limiting ring 110 to release the air from the massage air cushion 20, and then fold it for storage.

[0027] The second limiting ring with an outer diameter of 120 can be made in various specifications, which can be set according to the inner diameter of the air outlet of different hair dryers.

[0028] Among them, the sealing gasket 200 can be not just one set, but also two or three sets, etc., depending on the number of holes in the vent 130 on the side near the sealing gasket 200.

[0029] The sealing gasket 200 can be made of rubber, or it can be made of plastic or metal in the middle and rubber around the perimeter. The rubber will protrude a certain distance from the plane where the sealing gasket 200 is located, thereby achieving the purpose of increasing the sealing effect by squeezing the rubber. At the same time, it will not have a shorter service life due to the fact that the whole is made of rubber, and the middle is prone to sinking and affecting the seal. In this setting, the plastic or metal part in the middle at least partially abuts against the first limiting ring 110. The specific setting can be determined according to the actual situation.

[0030] In one embodiment, the first limiting ring 110 is at a first distance from one end of the core 100, and the first distance is equal to or greater than the vertical length of the sealing gasket 200.

[0031] In this embodiment, when the sealing gasket 200 abuts against the first limiting ring 110 and is in a sealed state, the bottom plane of the sealing gasket 200 will not protrude from the bottom plane of the core 100, thus avoiding accidental contact with the sealing gasket 200 during use, which could lead to misalignment of the sealing gasket 200. It can also further enhance the limiting effect and improve the sealing effect.

[0032] In one embodiment, a notch is provided on some of the core 100 of the sealing gasket 200. The bottom of the notch is flush with the top of the first limiting ring 110. A pressing part 320 is provided in the notch. At least one fixing member 310 is provided on the pressing part 320. The fixing member 310 extends vertically from one side of the pressing part 320, passing through the pressing part 320 and the first limiting ring 110 in sequence, and is fixed to the core 100.

[0033] In this embodiment, by fixing the gasket 200 to the notch via the fixing part 430 and the pressing part 320, when the gasket 200 needs to be replaced, it can be removed directly by removing the fixing part 310, thus achieving the continuous development of the valve core 10.

[0034] The fixing of the fastener 310 can be a conventional fixing method, such as setting a buckle groove on the core 100 and setting a buckle body at the end of the fastener 310. By inserting the end of the fastener 310 into the buckle groove, the purpose of buckling and fastening is achieved. The specific setting can be made according to the actual situation.

[0035] In one embodiment, the pressing part 320 is provided with a limiting groove, the sealing gasket 200 is partially disposed in the limiting groove, and the vertical length of the limiting groove is greater than the vertical length of the sealing gasket 200.

[0036] In this embodiment, the vertical length of the limiting groove is greater than the vertical length of the sealing gasket 200, so that the sealing gasket 200 does not need to be made of rubber that is more prone to aging, and creases do not need to be set. This is because after the sealing gasket 200 is subjected to external force, it can be displaced vertically to achieve the purpose of inflation or deflation. This setting method has higher material durability.

[0037] If the vertical length of the limiting groove is equal to the vertical length of the sealing gasket 200, the sealing gasket 200 cannot be directly displaced vertically and can only be flipped. In this working mode, the sealing gasket 200 set in the notch can be made of rubber or plastic with creases that can be flipped. This setting method makes the sealing gasket 200 flippable and the opening is more direct. The specific setting can be determined according to the actual situation.

[0038] In one embodiment, a seal 400 is provided at the other end of the core 100.

[0039] In this embodiment, the sealing effect is improved by setting the sealing element 400.

[0040] In one embodiment, the sealing member 400 includes a fixing part 430 and a flipping part 410 that is rotatably connected to the fixing part 430. The fixing part 430 is movably sleeved on the core 100, and the flipping part 410 is provided with an air plug 420 corresponding to the diameter of the vent hole 130.

[0041] In this embodiment, after inflation, the flip-over part 410 can be flipped over and its air plug 420 can be fastened onto the vent hole 130 to achieve a sealing purpose.

[0042] In one embodiment, a sealing ring 450 is provided around the gas plug 420.

[0043] In this embodiment, the sealing effect is further enhanced by setting a sealing ring 450.

[0044] In one embodiment, the flipping portion 410 is provided with an extended handhold portion 440.

[0045] In this embodiment, by providing a handheld part 440, when it is necessary to remove the air plug 420, the flipping part 410 can be flipped by applying force to the handheld part 440.

[0046] In one embodiment, the core 100 at the lower part of the second limiting ring 120 is provided with an inwardly recessed annular groove, and the fixing part 430 is provided with an annular collar corresponding to the annular groove, the annular collar being sleeved on the annular groove.

[0047] A massage air cushion 20 includes the aforementioned valve core 10 and the massage air cushion 20, wherein the valve core 10 is disposed on the massage air cushion 20 and provides an inflation port for the massage air cushion 20.

[0048] The sealing gasket 200 on the valve core 10 is located inside the massage air cushion 20.
