DETAILED DESCRIPTION OF THE EMBODIMENTS



[0042] In order to better understand the above objects, features and advantages of 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.

[0043] 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.

[0044] Referring to FIG. 1 to FIG. 13, the embodiment provides an air treatment device. The air treatment device comprises 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.

[0045] 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, so that outside air may enter the housing 1 from the air inlet 111 under a negative pressure formed by the fan.

[0046] For example, the air treatment device may be a heater, for example, for a user to perform operations such as heating. Certainly, the air treatment device may also be a humidifier, an air purifier and the like.

[0047] 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, so that effects of heating a plurality of people surrounding a furnace and then three-dimensional heating are achieved.

[0048] 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 used 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).

[0049] 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. Specifically, the opening and closing states comprise an opening state or a closing state; wherein the opening state comprises a fully opening state or a partially opening state.

[0050] 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, so that limitation of air outlet of the air treatment device is low.

[0051] 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, so as 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.

[0052] In the air treatment device provided by the embodiment, the sealing structure 2 is arranged on the housing 1, so that 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.

[0053] 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.

[0054] 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.

[0055] 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, so that 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.

[0056] 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.

[0057] 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 used 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] Certainly, 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.

[0063] 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.

[0064] In some embodiments, referring to FIG. 1 to FIG. 13, the sealing structure 2 comprises 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.
