The invention discloses a multistage combined secondary distillation heat control ultra-pure water continuous generator, relating to the technical field of high-purity water preparation. The multistage combined secondary distillation heat control ultra-pure water continuous generator is characterized in that a distiller main body is a cylinder body, and is separated into three regions of a primary distiller, a secondary distiller and a high-purity water storage chamber by an upper partitioning layer and a lower partitioning layer; the upper partitioning layer and the lower partitioning layer are circular glass with diameters equal to the diameter of the cylinder body as the distiller main body, and peripheries of the upper partitioning layer and the lower partitioning layer are adhered and connected with the inner wall of the distiller main body; a V-shaped condensing pipe is located at the upper part of the primary distiller; an outlet pipe of the primary condensing pipe and an inlet pipe of the primary condensing pipe respectively protrude out of the wall of the distiller main body, and the pipe wall and the wall of the distiller main body are adhered together; a quartz heating pipe is U-shaped, a U-shaped opening end of the quartz heating pipe protrudes out of the wall of the distiller, and the pipe wall and the wall of the distiller are adhered together; a secondary electric heating wire is connected with a secondary pressure regulator. According to the multistage combined secondary distillation heat control ultra-pure water continuous generator, the problem of secondary pollution of high-purity water of the prior art is solved; the heat efficiency is increased; the multistage combined secondary distillation heat control ultra-pure water continuous generator is small in volume, high in condensing efficiency and low in cost.

The invention provides a wet tissue heater convenient to operate. The wet tissue heater comprises a box body and a cover body; a first heating piece is arranged in the cover body; the box body is connected with the cover body through a connecting structure; and a limiting hook is arranged on the lower end face of the cover body. The connecting structure comprises a support housing, a rotating shaft rotationally connected into the support housing, a clamping hook matched with the limiting hook and a button. The clamping hook and the button are positioned on two sides of the rotating shaft respectively to form a warped plate structure; the upper end face of the support housing is provided with a through opening allowing the clamping hook to extend out; the side wall of the box body is provided with a window allowing the button to be exposed; the button is pressed to drive the clamping hook to rotate to separate the clamping hook from the limiting hook, and therefore, the cover body and the box body are separated in a matched mode, and separation operation is easy, convenient and labor-saving.
