Description

Technical Field

[0001] This utility model relates to the field of household range hood technology, and in particular to a range hood with dual activated carbon adsorption function. Background Technology

[0002] Chinese patent application number "CN201810677363.7" proposes a range hood that features a detachable air purification module and exhaust device, which facilitates cleaning and maintenance and improves user experience.

[0003] The aforementioned patent achieves the effect of filtering oil fumes through the set activated carbon module. However, in use, such as when stewing, the amount of irritating oil fumes produced is small, and there is no need to filter the oil fumes through activated carbon at this time. Since the existing technology cannot switch the use state of activated carbon, the activated carbon is always filtering, which causes the lifespan of the activated carbon to decrease too quickly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot switch the activated carbon usage state, and to propose a range hood with dual activated carbon adsorption function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The design includes a range hood body with dual activated carbon adsorption function, the upper end of which is connected to a device housing. The housing has openings at the top and bottom, and a top cover and a bottom cover are respectively fitted to the openings. Both the bottom cover and the top cover have through-holes for oil fume and air vents. The air vent located inside the bottom cover is also connected to a filter box.

[0007] Preferably, it further includes two sets of airflow switching components, which are respectively disposed inside the top cover and the bottom cover. Each airflow switching component includes a sliding cover, and the outer walls of the top cover and the bottom cover are equipped with slide rails. The sliding cover is connected to the free end of the slide rail.

[0008] Preferably, the fume vent is located in the middle of the top cover and the bottom cover, and the air vent is provided on each side of the fume vent.

[0009] Preferably, two sets of sliding covers are arranged opposite each other. When the two sets of sliding covers are in contact, they can seal the fume vent. When the two sets of sliding covers are separated, they can seal the air vent.

[0010] Preferably, the bottom cover has a double-layer structure, and the sliding cover slides inside the double-layer bottom cover.

[0011] Preferably, a cover plate is fastened to one side of the device housing.

[0012] Preferably, an activated carbon adsorption box is fitted inside the filter box.

[0013] The range hood with dual activated carbon adsorption function proposed in this utility model has the following advantages:

[0014] The filter box has a top cover and a bottom cover, both of which have fume vents and air vents. By changing the opening and closing of the fume vents and air vents, the filter box can be switched to different operating states, thereby improving its service life. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figures 1-5 A range hood with dual activated carbon adsorption function includes a range hood body 1. The upper end of the range hood body 1 is connected to a device housing 2. The housing has openings at the top and bottom. The top and bottom openings of the housing are respectively covered by a top cover 3 and a bottom cover 4. Both the bottom cover 4 and the top cover 3 have through openings for oil fume vents 5 and air vents 6. The air vent 6 located inside the bottom cover 4 is also connected to a filter box 7.

[0024] Furthermore, refer to Figures 2-5It also includes two sets of airflow switching components, which are respectively set in the top cover 3 and the bottom cover 4. The airflow switching components include a sliding cover 9. The outer walls of the top cover 3 and the bottom cover 4 are equipped with slide rails 8. The sliding cover 9 is connected to the free end of the slide rail 8. The fume vent 5 is opened in the middle of the top cover 3 and the bottom cover 4. The air vent 6 is located on both sides of the fume vent 5, and one set is opened on each side.

[0025] Furthermore, there are two sets of sliding covers 9 facing each other. When the two sets of sliding covers 9 are in contact, they can seal the fume vent 5. When the two sets of sliding covers 9 are separated, they can seal the air vent 6.

[0026] Furthermore, the bottom cover 4 has a double-layer structure, and the sliding cover 9 slides inside the double-layer bottom cover 4.

[0027] Furthermore, a cover plate 10 is fastened to one side of the device housing 2, and an activated carbon adsorption box is fastened inside the filter box 7.

[0028] Working principle:

[0029] When the sliding cover 9 in the top cover 3 covers the oil fume vent 5 and the sliding cover 9 in the bottom cover 4 covers the oil fume vent 5, it can be used in non-oil fume scenarios. Air is drawn in from the air vent 6 in the bottom cover 4, passes through the filter box 7 for filtration, and is discharged through the air vent 6 in the top cover 3, thus achieving the effect of air purification.

[0030] When the sliding cover 9 in the top cover 3 covers the air vent 6 and the sliding cover 9 in the bottom cover 4 covers the air vent 6, it can be used in the case of oil fume. Oil fumes are drawn in from the oil fume vent 5 in the bottom cover 4 and discharged from the oil fume vent 5 in the top cover 3, achieving a simple oil fume extraction effect.

[0031] When the sliding cover 9 in the top cover 3 covers the air vent 6 and the sliding cover 9 in the bottom cover 4 covers the oil fume vent 5, it can be used in oil fume scenarios. Oil fumes are drawn in from the air vent 6 in the bottom cover 4, pass through the filter box 7 for filtration, and are discharged through the oil fume vent in the top cover 3, thus achieving the effect of purifying and discharging oil fumes.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
