DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0027] Embodiment one: a kind of oil fume machine filter screen convenient to install and disassemble, including installation seat 1 and the collecting box 2 of setting in the bottom of installation seat 1, installation seat 1 bottom is provided with disassembly mechanism;

[0028] The dismounting mechanism comprises a mounting column 101, a handle 102, a limiting rod 103, a limiting spring 104, a limiting disc 105, a mounting groove 106, a spring pad 107, a reset spring 108, an extension rod 109, a clamping plate 110 and a reset plate 111, the mounting column 101 is fixedly connected to the bottom of the mounting base 1, the handle 102 is fixedly connected to the bottom of the limiting rod 103, the limiting disc 105 is fixedly connected to the outer surface of the limiting rod 103, the limiting spring 104 is movably connected to the outside of the limiting rod 103, the mounting groove 106 is arranged in the inner wall of the mounting base 1, the spring pad 107 is fixedly connected to the inner wall of the mounting groove 106, the extension rod 109 is fixedly connected to one side of the spring pad 107, the clamping plate 110 is fixedly connected to one side of the extension rod 109, the reset plate 111 is fixedly connected to one side of the clamping plate 110, the reset spring 108 is movably connected to the outside of the extension rod 109, and spring pads are arranged at both ends of the limiting spring 104 and the reset spring 108, which can protect the supporting surfaces at both ends of the limiting spring 104 and the reset spring 108. When the filter screen mounting plate 3 is installed and limited, the filter screen mounting plate 3 is clamped into the square groove arranged in the inner wall of the mounting base 1, and then the filter screen mounting plate 3 is pushed to the inner side of the square groove until the top of the limiting rod 103 is clamped into the limiting hole arranged on one side of the filter screen mounting plate 3, and at this time, the reset spring 108 is in a compressed state. When dismounting, the handle 102 is pulled down, so that the limiting rod 103 completely slides out of the limiting hole arranged on one side of the filter screen mounting plate 3, and at this time, the reset spring 108 in the compressed state generates a rebound force acting on one side of the clamping plate 110 under the action of its own restoring force, so that the reset plate 111 exerts a pushing force on the filter screen mounting plate 3, and at this time, the filter screen mounting plate 3 is pushed out of the sliding groove arranged in the inner wall of the mounting base 1, and the filter screen mounting plate 3 is dismounted.

[0029] In the embodiment one, the collecting mechanism is arranged on one side of the collecting box 2, and comprises a protrusion 201 and a limiting block 202. The protrusion 201 is fixedly connected to one side of the collecting box 2, and the limiting block 202 is fixedly connected to the bottom of the mounting base 1. A groove matched with the protrusion 201 is arranged on one side of the limiting block 202. The collecting box 2 can be installed on the bottom of the mounting base 1 by matching the protrusion 201 with the groove, and the collecting box 2 can be conveniently dismounted for cleaning when it is needed to be cleaned. Since the filter screen mounting plate 3 is arranged in an inclined state, oil stains will be attached to the surface of the filter screen of the filter screen mounting plate 3 after working for a period of time, and will slide down along the inclined surface of the filter screen mounting plate 3 and drop into the collecting box 2 under the action of gravity. The collecting box 2 can be directly dismounted from the limiting block 202 for cleaning.

[0030] The bottom of the mounting base 1 is provided with a filter screen mounting plate 3, and the top of the mounting base 1 is provided with a machine box 4. The filter screen mounting plate 3 is arranged in an inclined state, so that when the range hood is working, the oil stains adhering to the filter screen of the filter screen mounting plate 3 can slowly drip along the inclined surface of the filter screen mounting plate 3 to the collecting box 2 for centralized treatment. The filter screen mounting plate 3 is provided with a detachable filter screen on one side, and the top of the filter screen mounting plate 3 is provided with a limiting hole matched with a limiting rod 103. The filter screen mounting plate 3 is detached, and the filter screen is cleaned and replaced, which is convenient.

[0031] Working principle: first, when installing the filter screen, the filter screen mounting plate 3 is clamped into the inner wall of the groove in the mounting base 1, and the filter screen mounting plate 3 is pushed to the inner side of the groove until the top of the limiting rod 103 is clamped into the limiting hole on one side of the filter screen mounting plate 3, and the filter screen mounting plate 3 is installed and limited, and at this time, the return spring 108 is in a compressed state.

[0032] Further, when disassembling, only the handle 102 needs to be pulled down, so that the limiting rod 103 completely slides out of the limiting hole on the inner wall of one side of the filter screen mounting plate 3. At this time, the return spring 108 in the compressed state will generate a rebound force under the action of its own restoring force, and the rebound force acts on one side of the clamping plate 110, so that the return plate 111 exerts a pushing force on the filter screen mounting plate 3. At this time, the filter screen mounting plate 3 is pushed out of the sliding groove in the mounting base 1, and the filter screen mounting plate 3 can be disassembled.

[0033] Further, the filter screen is arranged on one side of the filter screen mounting plate 3, and the filter screen can be disassembled when cleaning.

[0034] Further, through the setting of the collecting mechanism, because the filter screen mounting plate 3 is arranged in an inclined state, after working for a period of time, oil stains will adhere to the surface of the filter screen of the filter screen mounting plate 3, and under the action of gravity, will slide down along the inclined surface of the filter screen mounting plate 3 and drip into the collecting box 2. The collecting box 2 can be directly detached from the limiting block 202 for cleaning.

[0035] It is to be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components.
