As preferably, described side plate is formed at the opposite sides of front plate, and the two ends of described side plate are equipped with described fixed plate.Also the surrounding of front plate can be made to be respectively provided with side plate, side plate for backlight, LCD display, Pcb plate spacing, be also used for the fixing of front plate and Pcb plate.Side plate two ends are provided with fixed plate and can ensure of the present utility model stable, and incessantly can arrange fixed plate in side plate two ends on side plate, and side plate middle part may also set up fixed plate.The quantitative relation that fixed plate is arranged, to man-hour spent during welding, in the case of ensureing the fixing and own stability of protective cover and Pcb plate, reduces width and quantity, the escapable cost of fixed plate.
As preferably, described fixed plate is welded and fixed with Pcb plate.If carrying out the fixing of protective cover and Pcb plate by securing member, the volume of device will certainly be increased.
As preferably, described side plate includes the epipleural corresponding to LCD display top and corresponding to the lower side panel bottom LCD display, and the length of described epipleural and lower side panel is all higher than or is equal to the length of LCD display.
As preferably, the one-body molded setting of described front plate, side plate and fixed plate.
The LCD display assembly (LCD display, backlight and Pcb plate) assembled can be inserted in the space that two side plates are formed; LCD display is made to be positioned at LCD display installing port; and make LCD display surface be close to front plate dorsal part; being relatively fixed of protective cover and LCD display is realized by being welded and fixed of the fixed plate of protective cover and Pcb plate; Pcb plate is fixed on in the housing of the device at LCD display assembly place again, the installation of protective cover can be completed.
This utility model is applied not only to the LCD display of air purifier; can also be used for other device with LCD display; by protective cover, the charged particle on LCD display is directed on the Pcb plate arranged in pairs or groups mutually with LCD display (or being directly grounded); need not arrange extra means just can avoid charged particle (electrostatic) to damage LCD display; can avoid LCD display flower screen, aging; and this utility model assembling is simple; protective cover is reliably fixed with LCD display, does not deposit the generation of protective cover skew LCD display phenomenon after a long time use.
