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

[0052] according to Figure 1 to Figure 21 As shown, this embodiment is an inflatable umbrella that is easy to inflate and deflate. It includes an umbrella handle 1, a push tube 2 connected below the umbrella handle, a rotating joint 3 rotatably connected to the upper part of the umbrella handle, fixedly connected to the rotating The gas control part 4 at the upper end of the joint, the umbrella frame fixing part 5 fixedly connected to the upper end of the gas control part, the inflatable support tube 6 arranged on the outer periphery of the umbrella frame fixing part, and the umbrella connected to the upper end of the inflatable support tube Face 7.

[0053] The upper part of the push cylinder is fixedly connected with a piston 22 which is slidably connected to the inner wall of the umbrella handle; the side wall of the push cylinder is located below the piston and is formed with a guide groove 23 arranged along the length of the push cylinder; Evenly distributed in the circumf...

Embodiment 2

[0071] according to Figure 1 to Figure 21 As shown, this embodiment is an inflatable umbrella that is easy to inflate and deflate. It includes an umbrella handle 1, a piston 2 slidably connected to the inner wall of the umbrella handle, and an umbrella surface connector rotatably connected to the upper part of the umbrella handle , And a hollow umbrella surface or a plurality of inflatable support tubes 6 connected to the umbrella surface connector and communicated with the umbrella surface connector; when the umbrella surface connector is connected to an inflatable support tube, each inflatable support tube is connected Umbrella 7;

[0072] The lower end of the outer wall of the umbrella handle is formed with a plurality of splints 17 uniformly arranged in the circumferential direction; a compression gap 171 is formed between the two adjacent splints; the outer side of the lower part of the umbrella handle is threaded with a twisting part 8; The lower part of the inner wall of...

Embodiment 3

[0076] according to Figure 22 As shown, the difference between this embodiment and Embodiment 1 is that the lower part of the inflatable support tube 6 is also connected with a first support rod 6a, a second support rod 6b, and a third support rod 6c from outside to inside; the first support rod 6a. The second support rod 6b and the third support rod 6c are hollow airbags; the inner end 6c of the third support rod is closed, and the other end is connected to the inflatable support tube; one end of the first support rod 6a is connected to the The outer end of the inflatable support tube is in communication, and the other end is in communication with the middle of the second support rod 6b; one end of the second support rod 6b is in communication with the inflatable support tube, and the other end is close to the closed end of the third support rod 6c. The position is connected; after the airbag is inflated, the lower first support rod 6a, the second support rod 6b, and the third...

Abstract

The invention discloses an inflatable umbrella easy to inflate and deflate, comprising a handle portion, a piston portion connected below the handle portion, a rotary connector rotationally connected to the upper portion of the handle portion, a gas control portion fixedly connected to the upper end of the rotary connector, a frame fixture fixedly connected to the upper end of the gas control portion, an inflating support tube disposed around the frame fixture, and an umbrella fabric connected to the upper end of the inflating support tube; a plurality of clamp plates arranged evenly around are formed at the lower end of the outer wall of the handle portion; a compression gap is formed between every two adjacent clamp plates; two symmetrically arranged one-way valves are fixedly mounted at the upper end of the handle portion; upon folding, a push barrel is moved up to a limit position, a knob portion is rotated clockwise, the clamp plates fasten the outer wall of the push barrel, and umbrella folding is achieved.

Description

Technical field [0001] The invention belongs to the field of umbrellas, and particularly relates to an inflatable umbrella that is convenient for inflating and deflating. Background technique [0002] The Chinese patent with the document number CN2386679Y discloses an inflatable and evacuable airbag frame umbrella. Its main purpose is to solve the problem that when the inflatable umbrella is used to wind up the umbrella surface, there is a small amount of air remaining in the airbag frame, which increases the difficulty of winding. . In this solution, the lower end of the storage airbag at the lower end is connected to the intake valve and the exhaust valve. The composite air control head is provided with a pressure relief valve composed of elastic sheets, rubber sheets, flaps, valve cores, etc.; when inflated, the valve core The air outlet and the rubber sleeve sleeved outside the air outlet constitute a one-way valve, which cooperates with the air inlet valve at the lower end ...
