[0033] Reference Figure 1 The connecting piece 4 is a zipper structure, and multiple inflatable strips 3 are fixed to the outer surface of the down jacket body 1 through multiple zippers. By using zippers to connect the inflatable strips 3, the connecting piece 4 and the down jacket body 1, they can be quickly removed and assembled, and the firmness of the inflatable strips 3 and the connecting piece 4 after assembly is ensured.

[0034] The working principle of this embodiment is as follows: the inflatable pillow assembly 2 can be assembled through any connecting piece 4 on the inner surface of the down jacket main body 1, so that the inflatable pillow assembly 2 can be used at any position of the neck or waist. The assembly position can be selected according to different environmental requirements to achieve a supporting effect on the neck or waist and relieve muscle soreness; in addition, by adding multiple inflatable strips 3, the down jacket has a floating effect in water, giving it an anti-drowning function. When sitting for a long time at work, the inflatable strips 3 can also achieve a certain supporting effect, thereby relieving muscle fatigue.

[0035] Example 2:

[0036] Reference Figure 2This embodiment provides an inflatable down jacket, including an inflatable pillow assembly 2, the inflatable pillow assembly 2 includes an inflatable pillow body 21, a push-type air pump 22, and a push-type exhaust valve 23. The two ends of the upper surface of the inflatable pillow body 21 are respectively provided with an air inlet and an air outlet that penetrate into the inner cavity, the push-type air pump 22 and the push-type exhaust valve 23 are respectively fixedly connected at the air inlet and the air outlet; the two ends of the inflatable pillow body 21 are fixedly connected with a snap fastener 5.

[0037] Reference Figure 2 An airtight cover (not shown in the figure) is provided on the top of the push-type air pump 22, and the airtight cover is fixedly connected to the upper surface of the inflatable pillow main body 21; the airtight cover is made of silicone material, and the provision of the airtight cover can improve the sealing performance of the connection between the push-type air pump 22 and the inflatable pillow main body 21; the chemical properties of silicone material are stable and not easy to cause irritation to the human body, and due to its softness, the airtight cover can avoid blocking the operation of the push-type air pump 22.

[0038] Reference Figure 3 The push-type air pump 22 includes a pump body shell 221, the bottom of the inner wall of the pump body shell 221 is fixedly connected to a bottom sealing plate 223, the inner cavity of the pump body shell 221 is slidably sleeved with a sliding cover 222, the top of the inner wall of the sliding cover 222 is transmission-connected to the top of the bottom sealing plate 223 through a first spring 224, the top of the sliding cover 222 is provided with a first ventilation pipe 225 penetrating into the interior, the inner wall of the first ventilation pipe 225 is installed with a first one-way valve 226 that only ventilates to the interior of the sliding cover 222, the top of the bottom sealing plate 223 is provided with a second ventilation pipe 227 that penetrates to the bottom of the bottom sealing plate 223, and the inner wall of the second ventilation pipe 227 is installed with a one-way valve that only ventilates to the bottom sealing plate 22 3. The second one-way valve 228 for bottom ventilation; the first ventilation pipe 225 runs through the top of the airtight cover. By pressing the sliding cover 222 downward, the internal space of the pump body shell 221 is reduced, and the internal air is discharged to the bottom of the bottom sealing plate 223 through the second one-way valve 228, thereby inflating the interior of the inflatable pillow body 21. When the pressure on the sliding cover 222 is released, the sliding cover 222 is lifted by the elastic force of the first spring 224. At this time, the internal space of the pump body shell 221 is increased. Under the influence of external air pressure, air enters the interior of the pump body shell 221 through the first one-way valve 226. This is repeated to achieve the pressing and pumping effect of the push-type air pump 22.

[0039] Reference Figure 3 A positioning slider is provided at the bottom end of the side wall of the sliding cover 222, and a positioning groove is provided on the inner wall of the pump body shell 221. The positioning slider is adapted to the positioning groove. By setting the positioning groove and the positioning slider, the sliding cover 222 can be prevented from falling off from the inside of the pump body shell 221.

By providing the O-ring and the plug cover 229, the air tightness between the pump body shell 221 and the sliding cover 222 and the sealing performance of the connection between the inside and outside of the pump body shell 221 can be improved. When the push-type air pump 22 is used, the plug cover 229 needs to be removed.

[0041] Reference Figure 4 The push-type exhaust valve 23 includes a valve body shell 231, a push cover 232 is slidably sleeved on the inner cavity of the valve body shell 231, and an exhaust nozzle 233 is provided on the side wall of the push cover 232 and is connected to the interior thereof. The bottom of the inner wall of the push cover 232 is fixedly connected to an inner fixing ring 235, and the bottom of the inner wall of the valve body shell 231 is fixedly connected to an inner fixing frame 234. The top of the inner fixing frame 234 is fixedly connected to a connecting column 236 with a diameter smaller than the inner diameter of the inner fixing ring 235. The top of the connecting column 236 passes through the inner cavity of the inner fixing ring 235 and is fixedly connected to a sealing plate 237 with a diameter larger than the inner diameter of the inner fixing ring 235. The top of the inner fixing frame 234 The inner portion is connected to the bottom of the inner fixed ring 235 through a second spring 238, and the top of the inner fixed ring 235 is covered by a sealing plate 237, so that the push-type exhaust valve 23 achieves a closing effect. When the pressing cover 232 is pressed, the inner fixed ring 235 can be driven to move downward, so that a gap is generated between the inner fixed ring 235 and the sealing plate 237. At this time, the gas can pass through the inner cavity of the inner fixed ring 235 into the interior of the pressing cover 232 and be discharged through the exhaust nozzle 233. When the pressing on the pressing cover 232 is cancelled, the inner fixed ring 235 can be reset under the elastic effect of the second spring 238, thereby realizing the exhaust effect of the push-type exhaust valve 23.

[0042] Reference Figure 5 The inflatable pillow main body 21 includes a pump body shell 221, and the outer surface of the pump body shell 221 is provided with a fabric 212; the pump body shell 221 is made of TUP material, and the fabric 212 is made of waterproof cloth. The TUP material has excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, and low temperature resistance. It has good oil resistance, chemical resistance and environmental resistance, and is a non-toxic material, so that the inflatable pillow main body 21 will not cause irritation to the human body and has a long service life.

[0043] The working principle of this embodiment: after the inflatable pillow component 2 is assembled, the inflatable pillow main body 21 can be inflated to form an air pillow by repeatedly pressing the push-type air pump 22, and the inflatable pillow main body 21 can be exhausted by pressing the push-type exhaust valve 23, so that the inflatable pillow main body 21 can be covered and stored conveniently. When the inflatable pillow component 2 is used in the neck position, the two ends of the inflatable pillow main body 21 can be tightened around the human neck by fastening the male and female buckles 5 at both ends of the inflatable pillow main body 21, so that the inflatable pillow component 2 has two loose and tight modes during use, which is convenient for different users.
