Embodiment <NUM>: a detachable inflatable sofa with a plurality of air cavities, as shown in <FIG>, includes a sofa cover <NUM> and a plurality of inflatable air cavities, where each adjacent two of the air cavities are detachably connected, and all the air cavities are connected to form a body of the sofa; and
the sofa cover is sleeved on an outer surface of the body.

The sofa cover, on the one hand, plays a role of fixing and shaping the air cavities, so that the assembled sofa does not deform. On the other hand, the inflatable sofa can be detached, i.e., the air cavities can be taken out from the sofa cover, and the air cavities can be detached for facilitating transportation and subsequent assembly; moreover, in the using process, if a certain air cavity is damaged, it can be replaced independently. Compared with an integrated structure with one air cavity, which can only be integrally scrapped after damage, the usage cost is greatly lowered.

When the inflatable sofa is not used or it is necessary to take the inflatable sofa outdoors for use, the air cavities can be taken out, and air is exhausted, so that the space is greatly saved, and it is convenient to store or carry.

In the embodiment, the inflatable sofa further includes an air pump, the air cavities are communicated through an air passage joint <NUM> and are detachably connected, and the air pump is communicated with one of the air cavities.

In the embodiment, any two connected air cavities are defined as a first air cavity and a second air cavity; the air passage joint includes a first connecting tube <NUM>, a second connecting tube <NUM> and a connecting sleeve <NUM>; one end of the first connecting tube is fixed to the first cavity, one end of the second connecting tube is fixed to the first air cavity, and the first connecting tube and the second connecting tube are in abutting joint and are relatively fixed through the connecting sleeve.

In the embodiment, the first connecting tube is provided with an external thread, the connecting sleeve is provided with an internal thread, an end part of the second connecting tube is provided with a flange <NUM> extending radially and outwardly, an end of the connecting sleeve is provided with a step <NUM> extending radially and inwardly, the connecting sleeve is sleeved on a peripheral surface of the second connecting tube, and the connecting sleeve rotates to drive the first connecting tube and the second connecting tube to be in abutting joint and to relatively lock and fix the first connecting tube and the second connecting tube.

Actually, there are many structures where the two connecting tubes are connected together through the connecting sleeve and are then detached, which are not described repeatedly one by one.

The first connecting tube is a rigid tube, and the second connecting tube is a rigid tube or a flexible tube.

In the embodiment, more preferably, the first connecting tube is the rigid tube for the convenience of machining a thread; and the second connecting tube is the flexible tube, and when the first connecting tube and the second connecting tube are in abutting joint, the flexible tube can play a role of increasing seal.

Either the first connecting tube or the second connecting tube can be the rigid tube. To guarantee the sealing property, a sealing structure such as a seal ring can be additionally arranged.

Of course, besides the specific structure of the air passage joint, there may be various structures of the air passage joint. For example, the structure only includes the first connecting tube and the second connecting tube, and the first connecting tube and the second connecting tube can be spliced together forcibly.

In the embodiment, a root of the second connecting tube is high frequency welded to the second air cavity; and.

a root of the second connecting tube is high frequency welded to the second air cavity. Not limited to this, other fixing modes can be adopted as long as the first connecting tube and the first air cavity and the second connecting tube and the second air cavity can be fixed.

In the embodiment, four air cavities are arranged and are a base air cavity <NUM>, a backrest air cavity <NUM>, a left armrest air cavity <NUM> and a right armrest air cavity <NUM> in sequence; the backrest air cavity is communicated with the base air cavity, the left armrest air cavity and the right armrest air cavity simultaneously, and the base air cavity, the left armrest air cavity and the right armrest air cavity are not communicated one another; and the air pump is internally arranged in the backrest air cavity.

The left armrest air cavity <NUM> and the right armrest air cavity <NUM> in the embodiment are distinguished after people sit on the sofa.

Of course, one air cavity neither refers to any one of the four air cavities. For example, the base air cavity and the left armrest air cavity can be made as a whole which is called one air cavity. Then the backrest air cavity and the right armrest air cavity can be made as a whole which is also called one air cavity. The following connecting modes are then adopted in front of the two air cavities. This structural form also falls into the scope of protection of the technique.

The air pump can be designed either internally or externally. Specifically, the air pump is internally arranged in one of the air cavities; internally arranging the air pump in a certain closed cavity belongs to the prior art, and the principle thereof is similar to that of an inflatable mattress with an internal pump. Therefore, the specific structures where the air pump and the air cavities are arranged internally are not described repeatedly one by one.

Or, one of the air cavities is provided with an inflating connector (the position of the sofa cover corresponding to the position can be provided with an opening for facilitating inflation), and the air pump is arranged externally and is capable of being communicated with the one of the air cavities through the inflating connector.

The air pump is an inflator pump or an air pump for inflation and exhaustion (an air pump with inflating and exhausting functions at the same time), and the inflator pump and the air pump for inflation and exhaustion both belong to the prior art, which are not described repeatedly.

In the embodiment, more preferably, the sofa cover is of an integrated structure.

The sofa cover is provided with an opening for the convenience of taking the air cavities out. Size, shape and position of the opening can be designed according to the size of the air cavities and the degree of convenience to take the air cavities.

The opening is connected to the sofa cover through a zipper or a magic tape. Not limited to this, the opening can be opened and then closed.

Of course, the sofa cover can further be of a split structure (spliced by a plurality of sheets), with slightly poor using effect.

Embodiment <NUM>: the structure of a detachable inflatable sofa with a plurality of air cavities is similar to that in the embodiment <NUM>. The difference lies in that as shown in <FIG>, a surface of at least one air cavities is provided with a heating pad <NUM>, and the heating pad is connected to a control panel <NUM>.

After being assembled, the heating pad is located between the surface of the air cavity and the sofa cover.

Of course, for facilitating operation of the control panel, the control panel is inevitably exposed out of the sofa cover.

More preferably, the control panel is located on the upper surface of the left armrest air cavity or the right armrest air cavity for the convenience of operation. More preferably, the heating pad is located on the surface of the backrest air cavity and/or the base air cavity to play an extremely heating role, so as to improve the comfort level.

More preferably, the air pump is internally arranged in the backrest air cavity, so that it can be directly communicated with the residual three air cavities simultaneously with high inflating efficiency and relatively ideal inflating effect; and moreover, compared with a condition that the air pump is located in the base air cavity, the air pump needs not to undertake most weight of a human body, so that the air pump is prevented from unnecessary damage and the like. If the air pump is arranged in the left armrest air cavity or the right armrest air cavity, although the air pump neither undertakes most weight of the human body, the purpose of being directly connected to the residual three air cavities cannot be achieved.

Embodiment <NUM>: the structure of a detachable inflatable sofa with a plurality of air cavities is similar to that in the embodiment <NUM>. The difference lies in that each adjacent two of the air cavities are not communicated, each of the air cavities is independently provided with an inflating connector corresponding thereto (not shown in the drawings), the corresponding air cavity is inflated through the inflating connector, and the sofa cover is sleeved on outer surfaces of the air cavities to realize shaping and detachable connection of all the air cavities.

That is to say, the plurality of air cavities in the embodiment are independent one another and are not communicated by an air passage. Each of the air cavities is independently inflated through the internally or externally arranged air pump, and all the air cavities are fixed and shaped through the sofa cover.

However, the embodiment <NUM> is superior to the embodiment. In the embodiment <NUM>, all the air cavities can be inflated through one internally arranged air pump, so that it is convenient and cost-saving; and in the embodiment, the plurality of air cavities can be inflated through a plurality of internally arranged air pumps, so that the weight of the product increases, and the cost of the product is improved.

Embodiment <NUM>: the structure of a detachable inflatable sofa with a plurality of air cavities is similar to that in the embodiment <NUM>. The difference lies in that a surface of at least one air cavity is provided with a heating pad, and the heating pad is connected to a control panel.
