Problems solved by technology

[0002] The Chinese patent with the document number CN2386679Y discloses an inflatable and pumpable airbag skeleton umbrella, the main purpose of which is to solve the problem that when the inflatable umbrella is rolled up after use, a small amount of air remains in the airbag skeleton, which increases the difficulty of winding.
In this scheme, the lower end of the air storage bag at the lower end is connected to the intake valve and the exhaust valve, and the composite air control head is provided with a pressure relief valve composed of elastic sheet, rubber sheet, mouth cover, valve core, etc.; The air outlet and the rubber sleeve set outside the air outlet constitute a one-way valve, which cooperates with the intake valve at the lower end of the air storage bag. When the air storage bag is pulled down, the pressure in the air storage bag decreases, and the intake valve opens (the exhaust valve closes). ), the air enters the air storage bag, when the air storage bag is pushed upward, the air is discharged from the air outlet into the composite air control head; when the inflatable umbrella is used, the exhaust valve is opened (the intake valve is closed), and the air storage bag is pushed upward, the air storage bag The air is discharged from the exhaust valve, but when the air storage bag is pulled down, the one-way valve formed by the air outlet on the valve core and the rubber sleeve set outside the air outlet cannot be conducted from the composite air control head to the air storage bag. , that is: the pressure relief device in the composite air control head cannot realize the exhaust function when the pressure in the airbag frame does not exceed the limit
[0003] Those skilled in the art should know that when it is necessary to achieve multiple inflation or pumping, two one-way valves with opposite conduction directions are required to achieve it. The solutions in the above patent documents cannot achieve the technical problems to be solved. Those skilled in the art also can't realize its scheme according to the record of its description

Embodiment 1

[0046] according to Figure 1-Figure 18 As shown, the present embodiment is an inflatable umbrella with a self-contained pump, including an umbrella shaft part 1, an inflating rod 2 connected under the umbrella shaft part, and an umbrella frame fixing part 5 fixedly connected to the umbrella shaft part, which is arranged on the The inflatable support tube 6 on the periphery of the umbrella frame fixing part, and the umbrella surface 7 connected to the upper end of the inflatable support tube.

[0047] The lower end of the umbrella shaft is fixedly sleeved with a limiting ring 25, and the lower end of the limiting ring is formed with a protruding ring, and the protruding ring is sleeved on the inflating rod.

[0048] The upper part of the side wall of the inflating rod is fitted with more than one rubber ring a21, and the diameter of the rubber ring is larger than the diameter of the protruding ring of the limiting ring; Gas leaks from the gap between the rubber ring a and the...

Embodiment 2

[0068] according to Figure 19 As shown, the difference between this embodiment and Embodiment 1 is that the bottom of the inflatable support tube 6 is also connected with the first support rod 6a, the second support rod 6b, and the third support rod 6c from the outside to the inside; the first support rod 6a, the second support rod 6b, and the third support rod 6c are hollow air bags; the inner end 6c of the third support rod is closed, and the other end communicates with the inflatable support tube; one end of the first support rod 6a is connected to the The outer end of the inflatable support tube communicates, and the other end communicates with the middle part of the second support rod 6b; one end of the second support rod 6b communicates with the inflatable support tube, and the other end communicates with the third support rod 6c near the closed end. The position is communicated; after the airbag is inflated, the first support rod 6a, the second support rod 6b, and the ...

Embodiment 3

[0070] according to Figure 20 , Figure 21 As shown, the difference between this embodiment and Embodiment 1 is that the umbrella frame fixing part 5 includes a lower fixing part 5a and an upper fixing part 5b fixedly sleeved; The film is formed; the two plastic films are an upper film 71 and a lower film 72, and a connecting port 721 is provided in the middle of the lower film, and the outer periphery of the connecting port of the lower film is clamped and fixedly connected to the upper fixing member and the lower fixing member between, and the upper fixing part and the lower fixing part are fixed by glue bonding or threaded connection.

[0071] The umbrella surface is formed with radial support tubes 73 in the radial direction, and each radial support tube is connected in the middle of the umbrella surface; the umbrella surface is formed with a circumferential support tube 74 between two adjacent radial support tubes; On both sides of each radial support tube are two radi...

Abstract

The invention discloses an inflatable umbrella with an inflator. The inflatable umbrella comprises an umbrella pole part, an inflating rod connected under the umbrella pole part, an umbrella stand fixing part fixedly connected to the umbrella pole part, inflating support pipes arranged at the periphery of the umbrella stand fixing part and an umbrella fabric connected to the upper ends of the inflating support pipes; a rotation shaft is molded in the center of the bottom of the inflating rod, and a positioning ring of which the diameter is larger than that of the rotation shaft is molded at the lower end of the rotation shaft; a rotating reversing part is rotatably connected to the rotation shaft in a sleeving mode. A user can change the switching-on direction of a one-way valve fixedly installed in an inner channel by rotating the rotating reversing part, and then the inflating support pipes can be inflated and deflated.
