The invention relates to a kettle. The kettle comprises a kettle body made of a metal material, a handle and a water gauge, wherein a window is formed in the kettle body, the water gauge is embedded in the window, and a seal ring is arranged between the window and the water gauge; the handle is detachably and fixedly connected with the kettle body; and the upper end of the window has an open structure which enables the water gauge to be embedded in the window, and the lower end of the window is of a closed structure. Compared with the prior art, the kettle has the advantages that since the upper end of the window has the open structure which enables the water gauge to be embedded into the window and the lower end of the window has the closed structure, the water gauge is pulled out from the window through the upper end of the window having the open structure and is embedded into the window after a new seal ring is changed when the seal ring leaks in the production process or the seal ring is aged and leaks in the using process and needs to be changed; and the seal ring is easy to change, the water gauge is simple and convenient to detach, destructive detachment on the water gauge is not needed, and the water gauge can be used repeatedly and has low maintenance or repairing cost.

A combustion apparatus (100) for a solid fuel, comprising a furnace chamber (10). A solid fuel (5) forms a material-piling layer (1) between a material inlet (11) and a furnace grate (14). An air inlet side (101) is formed at one side of the material-piling layer (1); a combustion side (102) is formed at the other side opposite the air inlet side (101). An open structure that does not limit the lateral shape of the material-piling layer (1) is formed outside the side of the material-piling layer (1) located at the combustion side (102). The combustion apparatus (100) allows for full combustion of a volatile (51).

The invention provides an earphone winding card which is made of hard material and in the shape of a card. The middle area of the earphone winding card is an earphone line winding area; the border area of the earphone winding card is provided with at least one bayonet which is open-structural and the edge of the bayonet is connected with the edge of the earphone winding card. By using the earphone winding card of the invention, earphone lines can be effectively wound and carried, the occupied space is small, the trouble of making knots is avoided, and the earphone winding card is convenient for use, simultaneously, the manufacturing cost is quite low.

The invention discloses a vehicle-mounted folding sunshade. Using the present invention, a foldable sunshade is composed of a roller shutter curtain type structure, which is installed in combination with a car roof rack, and is usually folded and installed on the top of the car. In order to block the sunlight; after use, the curtain sheet is recycled and wound on the rotating shaft, and the pull-out slide rail is retracted and locked. Since the sunshade is erected on the roof rack, and there is a gap between the sunshade and the body of the vehicle body, the sunshade is an open structure, and the sunshade function is completed without affecting the ventilation. And because the sliding rail push-pull method is used to complete the unfolding and folding recovery actions, the convenience in use can be improved compared with the overall wrapping soft-shell car jacket or car cover.

The present invention provides a sewage aeration treatment tower comprising a tower body (10), the top of the tower body (10) is connected with a sewage inlet pipe (11), the bottom of the tower body (10) is connected with an air discharge pipe (12) and an air intake pipe (13), the sewage aeration treatment tower further comprises an accumulation means (20) which is disposed at the middle of the tower body (10), both ends of the accumulation means (20) are opening structures the accumulation means (20) extends in the manner of gradually shrinking from bottom to top; the sewage aeration treatment tower further comprises a mixer (30), and the mixer (30) is arranged in the accumulation means (20). The sewage aeration treatment tower effectively solves the uneven mixing and insufficient contact problems between sewage and a gas in the prior art.
