In order to better understand the embodiments of the present disclosure, the solutions of the embodiments of the present disclosure will be further described below. It should be noted that, in case of no conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

Numerous specific details are set forth in the following description to facilitate a thorough understanding of the embodiments of the present disclosure, but the embodiments of the present disclosure can also be implemented in other ways different from those described here. Obviously, the embodiments described in the specification are merely a part of, rather than all of, the embodiments of the present disclosure.

Referring to FIG. 1 to FIG. 13, the embodiment provides an air treatment device. The air treatment device includes a housing 1. The housing 1 is provided with an air inlet 111, a top of the housing 1 is provided with an first air outlet 121 communicated with the air inlet 111, and a side part of the housing 1 is provided with a second air outlet 112 communicated with the air inlet 111.

In other words, an air flow channel is formed between the air inlet 111 and the first air outlet 121, and an air flow channel is also formed between the air inlet 111 and the second air outlet 112. In practice, for example, a fan may be arranged in the housing 1, and outside air may enter the housing 1 from the air inlet 111 under a negative pressure formed by the fan.

For example, the air treatment device may be a heater, for example, for a user to perform operations such as heating. The air treatment device may also be a humidifier, an air purifier and the like.

When the air treatment device is a heater, the housing 1 is internally provided with a heating member 6, and the heating member 6 can heat the air entering into the housing 1 to form hot air. In practice, when the first air outlet 121 on the top of the housing 1 is opened, the hot air flows out from the top of the housing 1 and rises rapidly, which is convenient for heating the top and also achieves rapid temperature rise in a three-dimensional space. When the second air outlet 112 on the side part of the housing 1 is opened, the hot air is forced to flow from the side part of the housing 1 to surrounding of the housing 1 firstly, and then continues to flow upward, and effects of heating a plurality of people surrounding a furnace and then three-dimensional heating are achieved.

Referring to FIG. 1 and FIG. 4, the housing 1 is further provided with a control structure 7. The control structure 7 may be, for example, a control knob, a control key and the like. The control structure 7 is electrically connected with the heating member 6 above, and is configured for controlling a heating state of the heating member 6 (for example, controlling the heating member 6 to start heating, stop heating, increase heating power, decrease heating power, and the like).

The housing 1 is provided with a sealing structure 2, and the sealing structure 2 moves relative to the housing 1 to adjust opening and closing states of at least one of the first air outlet 121 and the second air outlet 112. In one embodiment, the opening and closing states include an opening state or a closing state; and the opening state includes a fully opening state or a partially opening state.

With the arrangement, by controlling movement of the sealing structure 2, the opening and closing states of the first air outlet 121 may be adjusted, or the opening and closing states of the second air outlet 112 may be adjusted, or the opening and closing states of the first air outlet 121 and the second air outlet 112 may be adjusted at the same time, which may enable the air treatment device discharging air from different directions, and limitation of air outlet of the air treatment device is low.

When the opening and closing states of the first air outlet 121 and the second air outlet 112 are adjusted at the same time, for example, one of the first air outlet 121 and the second air outlet 112 may be in the opening state and the other one of the first air outlet 121 and the second air outlet 112 may be in the closing state, to achieve switch between top air outlet and side air outlet. For example, both the first air outlet 121 and the second air outlet 112 may be in the opening state.

In the air treatment device provided by the embodiment, the sealing structure 2 is arranged on the housing 1, and the sealing structure 2 can move relative to the housing 1 to adjust the opening and closing states of at least one of the first air outlet 121 on the top of the housing 1 and the second air outlet 112 on the side part of the housing 1. That is to say, by moving the sealing structure 2, for example, adjusting the opening and closing of the first air outlet 121 or the second air outlet 112, or adjusting the opening and closing of the first air outlet 121 and the second air outlet 112 at the same time, the air treatment device can discharge air from different directions, and thus achieving the flexible adjustment and switch air outlet directions of the air treatment device to a certain extent, reducing limitation of air outlet of the air treatment device, meeting different use requirements of the user for the air treatment device, and realizing good user experience.

In some embodiments, referring to FIG. 1 to FIG. 13, the sealing structure 2 moves relative to the housing 1 to adjust the opening and closing states of at least one of the first air outlet 121 and the second air outlet 112.

In other words, by controlling the sealing structure 2 to move upward and downward relative to the housing 1, the air outlet direction of the air treatment device can be adjusted flexibly, which reduces the limitation of air outlet of the air treatment device and meets the different use requirements of the user for the air treatment device.

In some embodiments, referring to FIG. 1 to FIG. 13, an elastic member 3 is arranged between the housing 1 and the sealing structure 2. One end of the elastic member 3 is fixed relative to the housing 1, and the other end of the elastic member 3 is fixed relative to the sealing structure 2, and the sealing structure 2 moves upward under an elastic force of the elastic member 3 to open at least part of the first air outlet 121.

The arrangement can improve convenience when the sealing structure 2 moves upward to open at least part of the first air outlet 121, adjust the opening and closing states of the first air outlet 121 conveniently, and improve moving convenience of the sealing structure 2.

In some embodiments, referring to FIG. 2 to FIG. 8, the housing 1 is provided with a first locking member 124, and the sealing structure 2 is provided with a second locking member 231. The first locking member 124 is configured for cooperating with the second locking member 231 to lock the sealing structure 2 on the housing 1 when the sealing structure 2 moves downward to shield at least part of the first air outlet 121.

With the arrangement, when the sealing structure 2 moves downward and shields the first air outlet 121, the sealing structure 2 can be locked on the housing 1 through the cooperating of the first locking member 124 and the second locking member 231, which may improve a position stability of the sealing structure 2 when covering the first air outlet 121 to a certain extent, and obtain a better covering effect on the first air outlet 121.

For example, when the sealing structure 2 is pressed to move downward until the first locking member 124 and the second locking member 231 are matched and locked together, the sealing structure 2 is locked on the housing 1 and shields at least part of the first air outlet 121. Meanwhile, when the sealing structure 2 is pressed again, the first locking member 124 and the second locking member 231 are disengaged, and the sealing structure 2 can be ejected upward under the elastic force of the elastic member 3 to make at least part of the first air outlet 121 be opened, which may achieve pressing rebound between the housing 1 and the sealing structure 2 and a high convenience of adjusting and using the air outlet direction.

In some embodiments, referring to FIG. 2, FIG. 3, FIG. 5 and FIG. 8, the first locking member 124 is a locking groove arranged on the housing 1, and the second locking member 231 is a locking cam arranged on the sealing structure 2 and clamped into the locking groove.

With the arrangement, it may achieve the locking and unlocking between the sealing structure 2 and the housing 1 through clamping the locking cam in the locking groove and removing the locking cam out of the locking groove, and thus achieve the adjustment of the opening and closing states of the first air outlet 121 by the sealing structure 2, and the convenience of adjusting the air outlet direction.

In some other embodiments, the first locking member 124 may also be a locking groove arranged on the sealing structure 2, and the second locking member 231 is a locking cam arranged on the housing 1 and clamped into the locking groove.

In some other embodiments, the sealing structure 2 can move upward and downward relative to the housing 1 by threaded fit between the sealing structure and the housing 1.

In some embodiments, referring to FIG. 1 to FIG. 13, the sealing structure 2 includes a top sealing member 21 and a side sealing member 22. The top sealing member 21 is located outside the top of the housing 1 and moves upward and downward relative to the housing 1 to adjust the opening and closing states of the first air outlet 121. The side sealing member 22 is located inside the housing 1 and moves upward and downward relative to the housing 1 to adjust the opening and closing states of the second air outlet 112.

That is to say, it can achieve the adjustment of a top air outlet state by the upward and downward movement of the top sealing member 21, and the adjustment of a side air outlet state by the upward and downward movement of the side sealing member 22, and thus adjust the air outlet direction of the air treatment device to a certain extent, which is flexible and convenient to use.

For example, by adjusting upward and downward movement distances of the top sealing member 21 and the side sealing member 22 relative to the housing 1, it can enable the top sealing member 21 and the side sealing member 22 being located at different positions relative to the first air outlet 121 and the second air outlet 112, and thus achieve the adjustment of air outlet areas and air outlet volumes of the air treatment device during top air outlet and side air outlet to a certain extent.

In some other embodiments, the side sealing member 22 may also be an annular sealing member with two open ends and sleeved outside the housing 1. For example, at least two connecting supporting members may be arranged between the top sealing member 21 and the side sealing member 22, and the at least two connecting supporting members are arranged at intervals along a circumferential direction of the side sealing member 22, and air holes are formed between the two adjacent connecting supporting members.

For example, when the sealing structure 2 moves upward relative to the housing 1, the side sealing member 22 is shielded at the second air outlet 112 on the side part of the housing, and the air hole described above is communicated with the first air outlet 121 on the top of the housing 1 to achieve top air outlet. When the sealing structure 2 moves downward relative to the housing 1, the side sealing member 22 is shielded at the first air outlet 121 on the top of the housing, and the air hole described above is communicated with the second air outlet 112 on the side part of the housing 1 to achieve side air outlet.

In some embodiments, referring to FIG. 1 to FIG. 13, the sealing structure 2 further includes a connecting bracket 23. The top sealing member 21 is arranged on a top of the connecting bracket 23, the top of the housing 1 is provided with an avoidance hole 125, and the connecting bracket 23 penetrates through the avoidance hole 125 to be connected with the side sealing member 22.

Connecting the top sealing member 21 and the side sealing member 22 together by the connecting bracket 23 can enable the top sealing member 21 and the side sealing member 22 moving upward and downward at the same time, which may achieve the adjustment of the opening and closing states of the first air outlet 121 and the second air outlet 112 at the same time, and a more convenience and more flexible adjustment of the air outlet direction.

For example, when the sealing structure 2 moves downward, the top sealing member 21 moves toward a direction close to the top of the housing 1 to shield at least part of the first air outlet 121, and meanwhile, the side sealing member 22 also moves downward together to expose at least part of the second air outlet 112, thus adjusting the air outlet direction of the air treatment device.

In some embodiments, referring to FIG. 2 to FIG. 6, the connecting bracket 23 is provided with a hollow cavity 233 with a bottom opening, and the elastic member 3 is located in the hollow cavity 233. The second locking member 231 is arranged in the hollow cavity 233.

The arrangement can protect the elastic member 3 and the second locking member 231 to a certain extent, ensure normal operation of the elastic member 3, the first locking member 124 and the first locking member 231, and improve the stability and convenience of the sealing structure 2 when adjusting the air outlet direction.

In some embodiments, referring to FIG. 2 to FIG. 6, the hollow cavity 233 is internally provided with a guide post 4, and the elastic member 3 is a spring sleeved on the guide post 4.

The arrangement may have a good guiding for the lifting movement of the sealing structure 2 relative to the housing 1, and ensure the stability in a lifting process, which may improve the stability and reliability when adjusting the air outlet direction to a certain extent.

In one embodiment, for example, a bottom end of the guide post 4 may be fixed in a fixing hole of the housing 1 by a screw, and an avoidance via hole for a top end of the guide post 4 to penetrate through is formed in a top cavity wall of the hollow cavity 233. When the top end of the guide post 4 is connected with a gasket 8 and the sealing structure 2 moves upward to expose the first air outlet 121, the gasket 8 abuts against one side of the top cavity wall of the hollow cavity 233 away from the first air outlet 121 to prevent the guide post 4 from coming out of the hollow cavity 233.

In some other embodiments, the elastic member 3, for example, may also be a gas spring, an elastic rope, an elastic strip, and the like.

In some other embodiments, the movement of the sealing structure 2 relative to the housing 1 described above may also refer to the rotation of the sealing structure 2 relative to the housing 1. For example, the sealing structure 2 rotates around a vertical rotating shaft to adjust the opening and closing states of the first air outlet and the second air outlet. For example, the sealing structure 2 includes a top shielding part and a side shielding part which are connected, and the top shielding part and the side shielding part can rotate around the vertical rotating shaft relative to the housing 1. The top shielding part can shield the first air outlet 121 or is staggered from the first air outlet 121 to expose at least part of the first air outlet 121. The side sealing member can shield the second air outlet 112 or is staggered from the second air outlet to expose at least part of the second air outlet 112. In this way, it may achieve the adjustment of the air outlet direction by the rotation of the sealing structure 2 relative to the housing 1.

In some embodiments, referring to FIG. 1 to FIG. 8, the top sealing member 21 is a sealing plate. With the arrangement, on one hand, it may improve a covering effect of the top sealing member 21 on the first air outlet 121 to a certain extent, and meanwhile, enable the top sealing member 21 being not limited by the arrangement of the first air outlet 121 when covering the first air outlet 121 for a covering range being wider. On the other hand, the user can also use the sealing plate as a bearing panel to place food for cooking, heating and keeping warm the food placed on the sealing plate through contact heat transfer.

In some embodiments, referring to FIG. 1 to FIG. 5, the first air outlet 121 is located in an area surrounded by a projection of the top sealing member 21 on the top of the housing 1. With the arrangement, when the top sealing member 21 descends to shield the first air outlet 121, the top sealing member 21 can completely cover the first air outlet 121, which make the covering effect on the first air outlet 121 be good.

Meanwhile, when the top sealing member 21 moves downward to shield the first air outlet 121, it can prevent the dust and the like from entering an inner chamber of the housing 1 to a certain extent, improve the cleanliness of the air treatment device to a certain extent, and ensure the air treatment effect.

In some embodiments, referring to FIG. 1 to FIG. 10, at least two first air outlets 121 are arranged, and the at least two first air outlets 121 are arranged at intervals along a circumferential direction of the top of the housing 1.
