Description

Technical Field

[0001] The utility model belongs to the technical field of bedding, in particular to an inflatable cushion. Background Art

[0002] At present, with the acceleration of the pace of modern life, it has become normal for people to sit for a long time while working and studying. This change in lifestyle has led to a growing concern for health issues in society, especially in the context of rapid development of science and technology and society, individuals pay more attention to body care than ever before. Therefore, choosing a cushion that is both comfortable and can effectively alleviate the negative effects of long-term sitting has become a consensus among many people.

[0003] For example, our company has previously applied for an adjustable inflatable hollow cushion (Announcement No.: CN 220676266 U), which includes a cushion, a cushion body, a hollow area and an airbag assembly; the cushion body corresponds to the user's buttocks; the hollow area is arranged on the cushion body, and the hollow area includes at least one hollow; the airbag assembly includes at least one airbag, which is arranged on the side of the cushion body away from the user's buttocks. The airbag can be inflated or deflated, and the inflation amount of the airbag can be changed during the patient's long-term sitting process to achieve the product's hardness and support adjustment, and personalized adjustment to the most comfortable state. It can not only meet the postoperative recovery of hemorrhoid patients, but also meet the personalized needs of ordinary users.

[0004] However, since this inflatable cushion only contains one airbag, the softness, hardness and support provided by the inflation level of the airbag are contradictory. If the inflation pressure reaches the maximum, the airbag can provide the maximum support and its hardness also reaches the maximum, resulting in a lack of comfort in the cushion. On the contrary, when the inflation pressure is insufficient, the entire cushion will easily sink, which cannot meet the postoperative recovery needs of hemorrhoid patients. Utility Model Content

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] See attached Figures 1 to 4 , an inflatable seat cushion, comprising: an airbag 100, a cushion body 200 and a detachable inflating device 300.

[0028] The airbag 100 includes a first accommodating chamber 110, a second accommodating chamber 120 and a third accommodating chamber 130 formed on the upper part of the first accommodating chamber 110 and located on both sides of the first accommodating chamber 110, respectively, a first air inlet and a second air inlet arranged on the second accommodating chamber 120 and the third accommodating chamber 130, and a one-way valve 140 allowing fluid to flow from the second accommodating chamber 120 and / or the third accommodating chamber 130 to the first accommodating chamber 110; the cushion body 200 is detachably mounted on the upper part of the second accommodating chamber 120 and the third accommodating chamber 130, corresponding to the user's buttocks. Whether inflated through the first air inlet or the second air inlet, the gas will first enter the first accommodating chamber until the first accommodating chamber reaches the maximum pressure state, and the second accommodating chamber 120 and the third accommodating chamber 130 will gradually inflate to a suitable hardness, so as to adjust the hardness of the inflatable cushion, thereby improving the comfort of the cushion and satisfying the postoperative recovery of hemorrhoid patients.

[0029] In a further embodiment, the pad body 200 includes: a main body 210, a leg guard 220 which is located near the user's knee and is bent downward along the airbag 100 to completely cover the side of the airbag 100. On the one hand, the leg guard 220 can release the pressure of the buttocks supporting alone, relieve the discomfort of the contact between the legs and the airbag 100, and increase the overall comfort; on the other hand, it can avoid long-term friction between the legs and the airbag 100, which affects the service life of the airbag 100.

[0030] In a further embodiment, the cushion body 200 is fixed to the outer surface of the airbag 100 by a connector, and the connector is a common connection method such as Velcro, a cloth cover structure, a hidden button, an elastic band, etc., which is convenient for storing and accommodating the inflatable seat cushion, and will not fall off during use. Specifically, the bottom of the main body 210 is fixedly connected to the upper surface of the airbag 100 by Velcro; the leg guard 220 is fixedly connected to the side surface of the airbag 100 by Velcro. The connection of multiple Velcros can ensure the connection stability between the cushion body 200 and the airbag 100.

[0031] In a further embodiment, the first air inlet and the second air inlet are equipped with a quick-insert female connector 160. The detachable inflatable device 300 is connected to the quick-insert female connector 160 via the quick-insert male connector 330 to inflate the second accommodating chamber 120 and / or the third accommodating chamber 130. When the quick-insert female connector 160 is disconnected from the quick-insert male connector 330, the quick-insert female connector 160 has a flow cutoff function to form a circuit breaker; when the quick-insert female connector 160 is connected to the quick-insert male connector 330, the quick-insert female connector 160 and the quick-insert male connector 330 are connected to form a passage. The coordinated use of the quick-insert female connector 160 and the quick-insert male connector 330 is not only convenient for users to quickly inflate and deflate, but also automatically closes when not connected, thereby avoiding accidental gas leakage and improving the convenience and safety of the inflatable seat cushion. See the attached Figure 4 The detachable inflatable device 300 includes: a connecting hose 310, an inflatable device 320 disposed on one side of the connecting hose 310, and a quick-insert male connector 330 disposed on the other side of the connecting hose 310. The inflatable device 320 can be a manually inflatable airbag 100 or a small electric blower.

[0032] In a further embodiment, the horizontal cross-section of the first accommodating chamber 110 in a fully inflated state is elliptical or approximately elliptical; the horizontal cross-section of the second accommodating chamber 120 and the third accommodating chamber 130 in a fully inflated state is semicircular or approximately semicircular. The second accommodating chamber 120 and the third accommodating chamber 130 form a hollow structure, which corresponds to the hemorrhoidal part of most patients, avoids problems such as excessive local pressure and poor blood circulation caused by sitting for a long time, does not aggravate the problem of the affected part of the hemorrhoids, and is more conducive to the recovery after hemorrhoid surgery.

[0033] In a further embodiment, the first accommodating chamber 110 is provided with an air outlet, and a detachable sealing plug 150 is provided at the air outlet to discharge the gas in the airbag 100, so as to facilitate the storage of the user.

[0034] In order to facilitate understanding of the technical solution of the inflatable seat cushion, a brief description of its working principle is given: during use, the detachable inflatable device 300 is connected to the quick-insert female connector 160 through the quick-insert male connector 330, and the second accommodating chamber 120 and / or the third accommodating chamber 130 are inflated. Whether inflating through the first air inlet or the second air inlet, the gas will preferentially enter the first accommodating chamber until the first accommodating chamber reaches the maximum pressure state, and the horizontal cross-section of the first accommodating chamber 110 in the fully inflated state is elliptical or approximately elliptical; then continue to inflate the second accommodating chamber 120 and / or the third accommodating chamber 130 until the hardness of the second accommodating chamber 120 and the third accommodating chamber 130 reaches a suitable degree, so as to adjust the hardness of the inflatable seat cushion, thereby improving the comfort of the seat cushion and satisfying the postoperative recovery of hemorrhoid patients.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
