[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Refer to the following Figures 1 to 6 The purification device and the desktop range hood according to some embodiments of the present application are described.

[0038] The present application provides a purification device, such as Figure 1 As shown, the purification device is used for a desktop range hood, which includes a casing and a fan 11 arranged in the casing. The casing is formed with a smoke inlet, and the inlet of the fan 11 is opposite to the smoke inlet. The purification device is arranged in the casing of the desktop range hood and in front of the fan 11, that is, the purification device is located between the smoke inlet of the casing and the inlet of the fan 11, so that after the smoke enters the casing, it needs to be purified by the purification device first and then discharged through the fan 11.

[0039] like Figure 1 and Figure 3 As shown, the purification device includes a first purification unit 1, which is formed with a first filling part 6. The first filling part 6 is used to fill a dehumidification filter element, such as a molecular sieve or silica gel, so that when the flue gas flows through the first filling part 6 of the first purification unit 1, the water vapor in the flue gas can be physically adsorbed by the dehumidification filter element, thereby efficiently removing water vapor from the flue gas.

[0040] The first purification unit 1 is also formed with a second filling portion 7, which is used to fill the deodorizing gel to deodorize the smoke. Specifically, the deodorizing gel can adsorb and decompose the odor molecules in the smoke, and at the same time, the fragrance molecules released by the deodorizing gel can cover and inhibit the undecomposed odor molecules. Compared with the traditional deodorizing method, that is, using an activated carbon fiber net or an activated carbon sponge to physically adsorb the odor molecules in the smoke to achieve deodorization, the deodorizing gel has a better decomposition and purification ability for odors.

[0041] Therefore, the purification device of the present application, by providing a first filling part 6 for filling a dehumidification filter element capable of physically adsorbing and removing water vapor, and providing a second filling part 7 for filling a deodorizing gel capable of adsorbing, decomposing and covering odor molecules, can effectively improve the dehumidification effect and odor removal effect of the purification device on flue gas, thereby enabling the desktop range hood using the purification device to have better dehumidification effect and odor removal effect.

[0042] In one embodiment of the present application, the dehumidification function and the deodorization function of the first purification unit 1 are integrated on the same plate frame.

[0043] In this embodiment, preferably, Figure 3 As shown, the first purification unit 1 includes a first plate frame 5. In the desktop range hood, one side of the first plate frame 5 in the thickness direction faces the smoke inlet of the casing, and the other side of the first plate frame 5 in the thickness direction faces the fan 11; the first plate frame 5 is formed with a plurality of channels, and the plurality of channels all penetrate through both sides of the first plate frame 5 in the thickness direction, and the plurality of channels are arranged in a honeycomb shape on the upper layer of the first plate frame 5.

[0044] A portion of the plurality of channels is used as the first filling portion 6 , and another portion is used as the second filling portion 7 .

[0045] For example, for a plurality of channels located in the same row, the first filling parts 6 and the second filling parts 7 are alternately arranged in sequence.

[0046] For another example, the first plate frame 5 includes a central area and a peripheral area surrounding the central area and close to the edge of the first plate frame 5. The holes located in the central area are used as the first filling part 6 to fill the dehumidification filter element, and the holes located in the peripheral area are used as the second filling part 7 to fill the deodorizing gel.

[0047] When the deodorizing gel is deodorizing the smoke, the deodorizing gel can react with the odor molecules in the smoke by odor diffusion to decompose and purify the odor molecules. When the dehumidification filter is dehumidifying the smoke, the smoke needs to pass directly between the dehumidification filters of the first filling part 6. For the first plate frame 5, the central area is the main area through which the smoke flows. Therefore, the pores in the central area are used as the first filling part 6, and the pores in the outer area are used as the second filling part 7. This can effectively ensure the dehumidification effect on the smoke without affecting the deodorization effect on the smoke.

[0048] In this embodiment, preferably, the deodorizing gel is a semisolid colloid substance, or the deodorizing gel is made into beads.

[0049] In this embodiment, preferably, the filling rate of the dehumidification filter in the first filling part 6 is 50%-60%, and the filling rate of the deodorizing gel in the second filling part 7 is 50%-90%, so that each channel can allow airflow to pass through to ensure smooth flow of smoke.

[0050] In this embodiment, preferably, both sides of the first plate frame 5 in the thickness direction are covered with gauze to ensure that the deodorizing gel in the first filling part 6 and the dehumidification filter in the second filling part 7 will not fall out, and at the same time will not affect the air permeability of the first plate frame 5.

When the dehumidification unit 3 and the deodorization unit 4 are installed at the same time, the dehumidification unit 3 and the deodorization unit 4 are arranged in sequence along the airflow direction of the smoke, that is, the airflow first flows through the dehumidification unit 3 and then flows through the deodorization unit 4.

[0054] In this embodiment, preferably, Figure 4 As shown, the multiple partition spaces of the second plate frame 8 are arranged side by side at intervals, and the vacant partition spaces and the partition spaces used as the filling parts 9 are arranged alternately in sequence, thereby ensuring the smooth flow of smoke and achieving deodorization or dehumidification.

[0055] Preferably, if Figure 5 As shown, when the length direction of the partition space extends along the vertical direction, a plurality of partitions 10 are further provided in the partition space, and the plurality of partitions 10 are spaced apart along the length direction of the partition space, so that when filling the deodorizing gel or the dehumidifying filter, it is possible to avoid the filler from accumulating in the lower part of the partition space and affecting the deodorizing or dehumidifying effect.

[0056] In this embodiment, preferably, Figure 6 As shown, the multiple partition spaces of the second plate frame 8 are arranged in a honeycomb shape, and the multiple partition spaces in the same row, the vacant partition spaces and the partition spaces used as filling parts 9 are arranged alternately in sequence, thereby ensuring both the smooth flow of smoke and a higher deodorization effect or dehumidification effect.

[0057] In this embodiment, preferably, for the second plate frame 8 of the deodorization unit 4, the side of the second plate frame 8 facing the fan 11 is the back side of the second plate frame 8, and the other side is the front side of the second plate frame 8, and a sealing plate is provided on the back side of the filling part 9 of the second plate frame 8 to prevent the deodorizing gel filled therein from falling out under the push of the smoke.

[0058] Preferably, for the second plate frame 8 of the dehumidification unit 3, the front and back sides of the filling portion 9 of the second plate frame 8 are provided with gauze to prevent the dehumidification filter from falling out.

[0060] In this embodiment, the second purification unit 2 is a composite filter, including a coarse filter and a high-efficiency filter. The coarse filter and the high-efficiency filter are arranged in sequence along the airflow direction of the flue gas. The coarse filter is made of a waterproof and breathable material, such as polytetrafluoroethylene, so as to filter large particles and oil and water in the flue gas through the coarse filter. The high-efficiency filter is a carbon-coated or multi-layer fiber filter, etc., so as to further remove particles and some ectopic molecules through the high-efficiency filter.

[0061] In this embodiment, preferably, Figure 1 and Figure 2 As shown, an oil cup 12 is further provided at the lower part of the casing, and the oil and water intercepted by the second purification unit 2 flows into the oil cup 12 under the action of gravity.
