Problems solved by technology
However, for an air bed with an inflatable table, it is necessary to inflate and discharge the air bed and the inflatable table separately, that is to say, it is necessary to install an air pump on the air bed and the inflatable table, which will inevitably increase the manufacturing cost of the air bed. Moreover, inflating separately will also cause inconvenience in use.

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 , 2 The vent valve shown includes a valve body 5 and a bonnet 2 buckled on the valve body 5, the space enclosed by the valve body 5 and the bonnet 2 is a valve chamber, and the valve body 5 is provided with an inlet communicating with the valve chamber. Air holes 51 and air outlet holes 52, such as Figure 8 As shown, the valve cover 2 is provided with a vent hole 21, such as figure 1 As shown, the gas channel formed between the air inlet 51 and the air outlet 52 is the first gas channel, and the gas channel formed between the air leakage hole 21 and the air outlet 52 is the second gas channel, and the valve cavity is also provided with The air hole adapter 4 is connected with the knob 1 on the valve cover 2, and the rotation of the air hole adapter 4 can be realized by turning the knob 1. The air hole adapt...

The invention provides a vent valve, which comprises a valve body and a valve cap fastened on the valve body. The valve body and the valve cap enclose to form a valve cavity, the valve body is provided with an air inlet hole and an air outlet hole which are communicated with the valve cavity, the valve cap is provided with an air releasing hole, a first air passage is formed between the air inlet hole and the air outlet hole, and a second air passage is formed between the air releasing hole and the air outlet hole. An air hole adaptor which is capable of rotating is arranged in the valve cavity and provided with through holes corresponding to the air inlet hole and the air releasing hole. The air hole adaptor is positioned at three state positions during rotating, when the air hole adaptor is positioned at a first state position, the first air passage is on while the second air passage is off; when the air hole adaptor is positioned at a second state position, the first air passage is off while the second air passage is on; and when the air hole adaptor is positioned at a third state position, the first air passage and the second air passage are both off. The vent valve is simple in structure, convenient in operation, safe, reliable, excellent in sealing and low in cost.
Description
technical field [0001] The present invention relates to a vent valve, in particular to a vent valve for inflatable products; the present invention also relates to an inflatable product provided with the vent valve. Background technique [0002] Traditional beds on the market generally cannot be folded, and the bed board is made of hard materials. When using it, a soft mattress needs to be laid on the bed board. limit. [0003] The appearance of the inflatable bed overcomes the defects of the traditional bed body being bulky and not easy to carry, and can be placed at will indoors or outdoors. The air bed generally includes an air pump and an inflation valve. When in use, the air bed should be inflated with the air pump, and the air should be deflated through the inflation valve after use. However, for an air bed with an inflatable table, it is necessary to inflate and discharge the air bed and the inflatable table separately, that is to say, it is necessary to install an a...
