Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a purification device for removing peculiar smell from air. Background Art

[0002] Air purifier, also known as air freshener or purifier, refers to a household appliance that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air. It is mainly divided into household, commercial, industrial, building, etc. There are many different technologies and media in air purifiers, enabling it to provide users with clean and safe air.

[0003] Most of the existing air purifiers have fixed air inlets. For example, an indoor odor purifier disclosed in announcement number CN218722075U needs to be moved when deodorizing a specific location because the air inlet is fixed, which is troublesome.

[0004] Therefore, we propose a purification device for removing air odor in order to solve the above-mentioned problems. Utility Model Content

[0010] The changing mechanism comprises a sliding sleeve slidably mounted on the outer side of the shell and an extension tube coiled on the sliding sleeve. The sliding sleeve is provided with a through hole connected to the extension tube, and the side wall of the shell is provided with a connecting port corresponding to the through hole.

[0011] Furthermore, the purification mechanism includes a fan, an activated carbon layer, an aromatherapy layer and a negative oxygen ion generator which are arranged in sequence from bottom to top.

[0012] Furthermore, the inner wall of the sliding sleeve is provided with a plurality of flexible rubber blocks which are engaged with the air inlet holes.

[0013] Furthermore, a filter is provided below the fan.

[0014] Preferably, a plurality of U-shaped clamping rings for clamping with the extension tube are arranged outside the sliding sleeve, and the clamping openings of the U-shaped clamping rings are converged inwards.

[0015] Preferably, a push plate is provided on the sliding sleeve.

[0016] Preferably, the outer wall of the shell is provided with a plurality of guide strips, and the inner wall of the sliding sleeve is provided with guide grooves slidably connected to the guide strips.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] By arranging a changing mechanism on the outside of the shell, the changing mechanism is normally located above the shell, and air is taken in through the air inlet. When air suction purification is required at a specific position, the extension tube is removed, the tube mouth is extended to the air suction position, and then the sliding sleeve is slid down to close the air inlet, and air is sucked in through the extension tube. The purification mechanism of the shell purifies the air and then discharges it. There is no need to move the purifier, and it is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 As shown, the utility model provides a purification device for removing odor from the air, comprising a housing 1, the housing 1 is preferably cylindrical, a plurality of air inlet holes 3 are provided on the bottom side wall of the housing 1, a plurality of air outlet holes are provided on the top of the housing 1, a purification mechanism 2 is provided inside the housing 1, and a change mechanism 4 is provided outside the housing 1;

[0026] The purification mechanism 2 includes a fan 21 , an activated carbon layer 22 , an aromatherapy layer 23 and a negative oxygen ion generator 24 which are arranged in sequence from bottom to top, and a filter 5 is arranged below the fan 21 .

[0027] After the fan 21 is started, the gas is sucked into the housing 1 through the air inlet 3, and the filter 5 blocks and filters large particles in the air. Then the gas passes through the activated carbon layer 22, and the activated carbon particles absorb the odor molecules in the air to achieve deodorization. The aromatherapy layer 23 volatilizes the aroma, and the negative oxygen ion generator 24 further improves the air quality by generating negatively charged oxygen ions.

[0028] The changing mechanism 4 includes a sleeve 41 slidably mounted on the outside of the shell 1 and an extension tube 42 coiled on the sleeve 41 . The sleeve 41 is provided with a through hole 43 connected to the extension tube 42 . The side wall of the shell 1 is provided with a connecting port 44 corresponding to the through hole 43 .

[0029] As a preferred technical solution of the utility model: a plurality of U-shaped clamping rings 6 are arranged outside the sliding sleeve 41 to be clamped with the extension tube 42, and the clamping mouths of the U-shaped clamping rings 6 are converged inwards, and the U-shaped clamping rings 6 play a fixing role on the extension tube 42 under normal conditions.

[0030] As a preferred technical solution of the utility model: a push plate 7 is provided on the sliding sleeve 41 , and the push plate 7 is convenient for the user to push and pull the sliding sleeve 41 .

[0031] As a preferred technical solution of the utility model: the inner wall of the sliding sleeve 41 is provided with a plurality of flexible rubber blocks 45 which are clamped with the air inlet hole 3. The flexible rubber blocks 45 fix the sliding sleeve 41 under normal conditions to prevent it from sliding down. After the sliding sleeve 41 slides down, the sealing between the sliding sleeve and the air inlet hole 3 can be strengthened.

[0032] As a preferred technical solution of the utility model: a plurality of guide strips 8 are arranged on the outer wall of the shell 1, and a guide groove 9 slidably connected to the guide strips 8 is opened on the inner wall of the sliding sleeve 41. The arrangement of the guide groove 9 and the guide strip 8 enables the sliding sleeve 41 to slide vertically only, preventing the through hole 43 from deviating from the connecting port 44 when the sliding sleeve 41 slides down.
