DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0057] Reference Figures 1 to 13 As shown, this embodiment provides an air treatment device. The air treatment device includes a housing 1, an air inlet 111 is provided on the housing 1, a first air outlet 121 connected to the air inlet 111 is provided on the top of the housing 1, and a second air outlet 112 connected to the air inlet 111 is provided on the side of the housing 1.

[0058] That is, 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 specific implementation, for example, a fan can be arranged in the housing 1, so that external air can enter the housing 1 through the air inlet 111 under the action of the negative pressure formed by the fan.

[0059] Exemplarily, the air treatment device may be a heater, for example, for users to perform heating operations, etc. Of course, the air treatment device may also be a humidifier, an air purifier, etc.

[0060] Among them, when the air handling device is a heater, a heating element 6 is provided in the shell 1, and the heating element 6 can heat the air entering the shell 1 to form hot air. In specific implementation, when the first air outlet 121 at the top of the shell 1 is opened, the hot air flows out from the top of the shell 1 and rises quickly, which is convenient for heating the top and also realizes rapid temperature rise in the three-dimensional space. When the second air outlet 112 on the side of the shell 1 is opened, the hot air is forced to flow from the side of the shell 1 to the surrounding of the shell 1, and then continue to flow upward, thereby realizing the effect of multiple people heating around the stove first and then three-dimensional temperature rise.

[0061] Reference Figure 1 and Figure 4 As shown, a control structure 7 is also provided on the housing 1, and the control structure 7 can be, for example, a control knob, a control button, etc. The control structure 7 is electrically connected to the heating element 6 and is used to control the heating state of the heating element 6 (for example, control the heating element 6 to start heating, end heating, increase heating power, reduce heating power, etc.).

[0062] The housing 1 is provided with a sealing structure 2, which can move relative to the housing 1 to adjust the opening and closing state of at least one of the first air outlet 121 and the second air outlet 112. Specifically, the opening and closing state here includes an open state or a closed state; wherein the open state includes fully open or partially open.

[0063] With such an arrangement, the movement of the sealing structure 2 can be controlled to adjust the opening and closing state of the first air outlet 121, or the opening and closing state of the second air outlet 112, or the opening and closing states of the first air outlet 121 and the second air outlet 112 can be adjusted at the same time, so that the air treatment device can discharge air from different directions. In this way, the air outlet limitation of the air treatment device is low.

[0064] Among them, 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 can be placed in an open state, and the other of the first air outlet 121 and the second air outlet 112 can be placed in a closed state, thereby realizing switching between top air outlet and side air outlet; for example, both the first air outlet 121 and the second air outlet 112 can be placed in an open state.

[0065] The air treatment device provided in this embodiment is provided with a sealing structure 2 on the shell 1 so that the sealing structure 2 can move relative to the shell 1 to adjust the opening and closing state of at least one of the first air outlet 121 opened on the top of the shell 1 and the second air outlet 112 opened on the side of the shell 1. That is to say, by moving the sealing structure 2, for example, the opening and closing of the first air outlet 121 can be adjusted, or the opening and closing of the second air outlet 112 can be adjusted, or the opening and closing of the first air outlet 121 and the second air outlet 112 can be adjusted at the same time, so that the air treatment device can discharge air from different directions, thereby realizing flexible adjustment and switching of the air outlet direction of the air treatment device to a certain extent, reducing the limitations of the air outlet of the air treatment device, meeting the different usage requirements of the user for the air treatment device, and providing a good user experience.

[0066] In some embodiments, reference Figures 1 to 13 As shown, the sealing structure 2 can move up and down relative to the housing 1 to adjust the opening and closing state of at least one of the first air outlet 121 and the second air outlet 112 .

[0067] That is to say, by controlling the sealing structure 2 to move up and down relative to the shell 1, the air outlet direction of the air treatment device can be adjusted. The adjustment method is flexible, which reduces the limitations of the air outlet of the air treatment device and meets the different usage requirements of users for the air treatment device.

[0068] In some embodiments, reference Figures 1 to 13 As shown, an elastic member 3 is provided between the housing 1 and the sealing structure 2. One end of the elastic member 3 is relatively fixed to the housing 1, and the other end of the elastic member 3 is relatively fixed to the sealing structure 2, so that the sealing structure 2 moves upward under the elastic force of the elastic member 3, so that at least part of the first air outlet 121 is opened.

[0069] This arrangement can improve the convenience when the sealing structure 2 moves upward to open at least part of the first air outlet 121, and the opening and closing state of the first air outlet 121 is convenient to adjust, thereby improving the convenience of moving the sealing structure 2.

[0070] In some embodiments, reference Figures 2 to 8 As shown, a first locking member 124 is provided on the shell 1, and a second locking member 231 is provided on the sealing structure 2. The first locking member 124 is used to cooperate with the second locking member 231 to lock the sealing structure 2 on the shell 1 when the sealing structure 2 moves downward to cover at least part of the first air outlet 121.

[0071] With such arrangement, when the sealing structure 2 moves downward and covers the first air outlet 121, the sealing structure 2 can be locked on the shell 1 through the cooperation of the first locking member 124 and the second locking member 231, thereby improving the stability of the position of the sealing structure 2 when covering the first air outlet 121 to a certain extent, and achieving a good covering effect on the first air outlet 121.

[0072] 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 locked together, the sealing structure 2 is locked on the housing 1 and covers at least part of the first air outlet 121. At the same time, 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, so that at least part of the first air outlet 121 is opened, thus realizing the pressing rebound between the housing 1 and the sealing structure 2, and the air outlet direction is adjusted with high convenience.

[0073] In some embodiments, reference Figure 2 , Figure 3 as well as Figure 5 and Figure 8 As shown, the first locking member 124 is a locking groove provided on the housing 1 , and the second locking member 231 is a locking protrusion provided on the sealing structure 2 and can be inserted into the locking groove.

[0074] With this arrangement, the locking and unlocking between the sealing structure 2 and the shell 1 can be achieved by snapping the locking protrusion into and out of the locking groove, thereby achieving the adjustment of the opening and closing state of the first air outlet 121 by the sealing structure 2, and the air outlet direction is easy to adjust.

[0075] Of course, in other embodiments, the first locking member 124 may also be a locking groove provided on the sealing structure 2 , and the second locking member 231 may be a locking protrusion provided on the housing 1 and capable of being inserted into the locking groove.

[0076] In some other embodiments, the sealing structure 2 and the shell 1 may be threadedly matched to achieve the vertical movement of the sealing structure 2 relative to the shell 1 .

[0077] In some embodiments, reference Figures 1 to 13 As shown, the sealing structure 2 includes a top sealing member 21 and a side sealing member 22. The top sealing member 21 is located on the outside of the top of the housing 1 and can move up and down relative to the housing 1 to adjust the opening and closing state of the first air outlet 121. The side sealing member 22 is located on the inside of the housing 1 and can move up and down relative to the housing 1 to adjust the opening and closing state of the second air outlet 112.

[0078] That is to say, the top air outlet state is adjusted by moving the top sealing member 21 up and down, and the side air outlet state is adjusted by moving the side sealing member 22 up and down, thereby adjusting the air outlet direction of the air treatment device to a certain extent, which is flexible and convenient to use.

[0079] Exemplarily, by adjusting the up and down movement distance of the top sealing member 21 and the side sealing member 22 relative to the shell 1, the top sealing member 21 and the side sealing member 22 are located at different positions relative to the first air outlet 121 and the second air outlet 112, thereby being able to achieve a certain degree of adjustment of the air outlet area and air volume when the air treatment device is discharged from the top and sides.

[0080] In other implementations, the side sealing member 22 can also be an annular sealing member with open ends, and can be sleeved on the outside of the shell 1. For example, at least two connecting supports can be arranged between the top sealing member 21 and the side sealing member 22, and at least two connecting supports can be arranged at intervals along the circumference of the side sealing member 22, and air holes are formed between two adjacent connecting supports.

[0081] For example, when the sealing structure 2 moves upward relative to the housing 1, the side sealing member 22 covers the second air outlet 112 at the side of the housing, and the air hole is connected to the first air outlet 121 at the top of the housing 1 to achieve top air outlet. When the sealing structure 2 moves downward relative to the housing 1, the top sealing member 21 covers the first air outlet 121 at the top of the housing, and the air hole is connected to the second air outlet 112 at the side of the housing 1 to achieve side air outlet.

[0082] In some embodiments, reference Figures 1 to 13 As shown, the sealing structure 2 further includes a connecting bracket 23. The top sealing member 21 is arranged on the top of the connecting bracket 23, and a avoiding hole 125 is opened on the top of the shell 1. The connecting bracket 23 passes through the avoiding hole 125 to connect with the side sealing member 22.

[0083] In this way, the top sealing member 21 and the side sealing member 22 are connected together by the connecting bracket 23, so that the top sealing member 21 and the side sealing member 22 can be moved up and down at the same time, so that the opening and closing states of the first air outlet 121 and the second air outlet 112 can be adjusted at the same time, and the adjustment of the air outlet direction is more convenient and more flexible.

[0084] Exemplarily, when the sealing structure 2 moves downward, the top sealing member 21 moves toward the top of the shell 1 to cover at least part of the first air outlet 121, and at the same time, the side sealing member 22 also moves downward to expose at least part of the second air outlet 112, thereby adjusting the air outlet direction of the air treatment device.

[0085] In some embodiments, reference Figures 2 to 6 As shown, the connecting bracket 23 has a hollow cavity 233 with an opening at the bottom, and the elastic member 3 is located in the hollow cavity 233. The second locking member 231 is disposed in the hollow cavity 233.

[0086] This arrangement can protect the elastic member 3 and the second locking member 231 to a certain extent, ensure the normal operation of the elastic member 3, the first locking member 124 and the second locking member 231, and improve the stability and convenience of the sealing structure 2 when adjusting the air outlet direction.

[0087] In some embodiments, reference Figures 2 to 6 As shown, a guide column 4 is further provided in the hollow cavity 233 , and the elastic member 3 is a spring sleeved on the guide column 4 .

[0088] Such an arrangement can well guide the lifting and lowering movement of the sealing structure 2 relative to the shell 1, ensuring stability during the lifting process, thereby improving the stability and reliability of the air outlet direction adjustment to a certain extent.

[0089] Specifically, the bottom end of the guide column 4 can be fixed in the fixing hole of the shell 1 by screws, and an avoidance hole for the top end of the guide column 4 to pass through is opened on the top cavity wall of the hollow cavity 233. The gasket 8 is connected to the top end of the guide column 4, and when the sealing structure 2 is moved upward to expose the first air outlet 121, the gasket 8 abuts against the side of the top cavity wall of the hollow cavity 233 away from the first air outlet 121 to prevent the guide column 4 from falling out of the hollow cavity 233.

[0090] Of course, in other embodiments, the elastic member 3 may also be, for example, a gas spring, an elastic rope, an elastic strip, etc.

[0091] In other embodiments, the above-mentioned movement of the sealing structure 2 relative to the shell 1 may also refer to the rotation of the sealing structure 2 relative to the shell 1, for example, the sealing structure 2 rotates around a vertical axis, so as to adjust the opening and closing state of the first air outlet and the second air outlet. Exemplarily, the sealing structure 2 includes a top shielding portion and a side shielding portion connected to each other, and the top shielding portion and the side shielding portion can rotate relative to the shell 1 around a vertical axis. Among them, the top shielding portion can block the first air outlet 121, or staggered with the first air outlet 121 to reveal at least part of the first air outlet 121. The side shielding portion can block the second air outlet 112, or staggered with the second air outlet 112 to reveal at least part of the second air outlet 112. In this way, the adjustment of the air outlet direction is achieved by rotating the sealing structure 2 relative to the shell 1.

[0092] In some embodiments, reference Figures 1 to 8 As shown, the top sealing member 21 is a sealing flat plate. This arrangement, on the one hand, can improve the covering effect of the top sealing member 21 on the first air outlet 121 to a certain extent, and at the same time, the top sealing member 21 is not limited by the arrangement of the first air outlet 121 when covering the first air outlet 121, and the covering range is wider; on the other hand, the user can also use the sealing flat plate as a bearing panel to place food, etc., so as to cook, heat, and keep warm the food placed on the sealing flat plate by contact heat transfer.

[0093] In some embodiments, reference Figures 1 to 5 As shown, the first air outlet 121 is located in the area surrounded by the projection of the top sealing member 21 on the top of the housing 1. With this arrangement, when the top sealing member 21 descends to cover the first air outlet 121, the top sealing member 21 can completely cover the first air outlet 121, and the covering effect of the first air outlet 121 is good.

[0094] At the same time, when the top sealing member 21 moves downward to cover the first air outlet 121, it can also prevent dust and the like from entering the inner cavity of the shell 1 to a certain extent, thereby improving the cleanliness of the air treatment device to a certain extent and ensuring the air treatment effect.

[0095] In some embodiments, reference Figures 1 to 10 As shown, there are at least two first air outlets 121, and at least two first air outlets 121 are arranged at intervals along the circumferential direction of the top of the housing 1. This arrangement can improve the uniformity of air outlet from the top of the air treatment device to a certain extent, and the air treatment effect is good.

[0096] In some embodiments, reference Figures 1 to 13 As shown, the side sealing member 22 is an annular sealing plate, which is circumferentially arranged along the inner wall of the shell 1.

[0097] This arrangement can improve the covering effect of the side sealing member 22 on the second air outlet 112 to a certain extent. At the same time, the side sealing member 22 is not limited by the arrangement of the second air outlet 112 when covering the second air outlet 112, and the covering range is wider.

[0098] In some embodiments, reference Figures 1 to 13 As shown, the height dimension of the projection of the side sealing member 22 on the vertical plane is not less than the height dimension of the projection of the opening area of ​​the second air outlet 112 on the vertical plane. Figure 1 The area defined between the upper edge and the lower edge of the second air outlet 112 in the vertical direction of the middle air handling device. The above-mentioned height dimension specifically refers to the absolute height of the corresponding projection.

[0099] This arrangement enables the side sealing member 22 to completely cover the second air outlet 112 in the vertical plane, thereby improving the covering effect of the second air outlet 112 to a certain extent, and the adjustment range of the air outlet area is larger.

[0100] In some embodiments, reference Figures 1 to 6 As shown, there are at least two second air outlets 112, and at least two second air outlets 112 are arranged at intervals along the circumference of the shell 1. This arrangement can improve the uniformity of the air outlet from the side of the air treatment device to a certain extent, and the air treatment effect is good. For example, when the air treatment device is a heater, the above arrangement can achieve the heating effect of the user around the stove, and the heat dissipation range is large.

[0101] In some embodiments, reference Figures 1 to 6 As shown, the housing 1 is a hollow cylindrical housing. This arrangement can improve the smoothness of air flow in the housing 1 and the uniformity of the air flow field to a certain extent, and the air treatment effect is good.

[0102] In some embodiments, reference Figures 1 to 10 As shown, the housing 1 includes a hollow barrel body 11 with an opening at the top and a top cover 12 covering the opening, at least part of the air inlet 111 is opened on the barrel body 11, and at least part of the second air outlet 112 is opened on the side wall of the barrel body 11. In specific implementation, for example, the barrel body 11 can be a hollow cylindrical barrel body. Among them, at least part of the first air outlet 121 is opened on the top cover 12.

[0103] For example, at least part of the air inlet 111 can be opened at the bottom of the side wall of the barrel body 11; of course, at least part of the air inlet 111 can also be opened at the bottom wall of the barrel body 11. For example, at least part of the second air outlet 112 can be opened at the top of the side wall of the barrel body 11. Among them, the top cover 12 can be detachably connected to the barrel body 11 by screws, etc., or the two can be integrally formed.

[0104] In some embodiments, reference Figures 1 to 10 As shown, the top cover 12 has a receiving groove 123 that is recessed in a direction away from the top sealing member 21, a portion of the connecting bracket 23 is located in the receiving groove 123, and the connecting bracket 23 can move up and down along the receiving groove 123, the avoidance hole 125 is provided at the bottom of the receiving groove 123, and at least a portion of the first air outlet 121 is located outside the receiving groove 123. In other words, at least a portion of the first air outlet 121 is provided on a portion of the top cover 12 where the receiving groove 123 is not provided.

[0105] With such an arrangement, when the connecting bracket 23 is moved up and down relative to the shell 1, the accommodating groove 123 can guide the connecting bracket 23 to a certain extent, thereby improving the stability and reliability of the up and down movement of the sealing structure 2, making it convenient and stable to adjust the air outlet direction of the air conditioning device, and the air outlet of the air treatment device is stable.

[0106] Specifically, for example, the bottom end of the guide column 4 , the bottom end of the spring, and the first locking member 124 may be relatively fixed on the bottom groove wall of the accommodating groove 123 .

[0107] Exemplarily, the avoidance hole 125 may also be provided on the side wall of the accommodating groove 123 . In this case, the avoidance hole is a strip-shaped hole extending along the groove depth direction of the accommodating groove 123 .

[0108] When the sealing structure 2 and the shell 1 are threadedly matched to achieve the vertical movement of the sealing structure 2 relative to the shell 1, an internal thread can be provided on the outer wall of the connecting bracket 23, and an external thread matching the internal thread can be provided on the groove wall of the accommodating groove 123, and the avoidance hole 125 can be arranged along the circumferential direction of the groove bottom of the accommodating groove 123, and can allow the connecting bracket 23 to rotate along the axial direction of the shell 1. In this way, when the sealing structure 2 is screwed, the sealing structure 2 can be driven to move up and down relative to the shell 1.

[0109] In some embodiments, reference Figures 1 to 13 As shown, the connecting bracket 23 includes a frame body 234 and a supporting platform 235 disposed on the top of the frame body 234 , the top sealing member 21 is disposed on the supporting platform 235 , and the frame body 234 is located in the receiving groove 123 .

[0110] This arrangement enables the support platform 235 to achieve stable support and good bearing capacity for the top sealing member 21, thereby improving the stability of the top sealing member 21 to a certain extent, so that the top sealing member 21 has a good covering effect on the first air outlet 121, and can also well bear the food on the top sealing member 21, thereby achieving good cooking heating and heat preservation effects.

[0111] In some embodiments, reference Figures 1 to 8 As shown, the bottom surface of the support platform 235 matches the top surface shape of the top cover 12. This arrangement enables the support platform 235 to stably support the top sealing member 21 while also being able to cooperate with the top sealing member 21 to cover the first air outlet 121 well, thereby ensuring stable adjustment of the air outlet direction.

[0112] In some embodiments, reference Figures 2 to 13 As shown, the connecting bracket 23 is provided with a connecting protrusion 232 extending toward the side sealing member 22 , the connecting protrusion 232 passes through the avoidance hole 125 , and the side sealing member 22 is provided with a positioning hole 221 for the connecting protrusion 232 to be inserted.

[0113] In this way, the connection between the connecting bracket 23 and the side sealing member 22 is achieved through the matching between the connecting protrusion 232 and the positioning hole 221, and the connection and assembly are simple and efficient.

[0114] In some embodiments, reference Figures 2 to 13 As shown, a connecting plate 222 is connected to the bottom of the annular sealing plate, a ventilation gap 223 communicating with the air inlet 111 is formed between the connecting plate 222 and the inner cavity of the annular sealing plate, and a positioning hole 221 is provided on the connecting plate 222 .

[0115] By such arrangement, external air enters the inner cavity of the shell 1 through the air inlet 111 and is processed by the heating element 6 etc., and then flows to the outside of the air treatment device through the ventilation gap 223, the inner cavity of the annular sealing plate and then through at least one of the first air outlet 121 and the second air outlet 112, so as to provide heating for the user.

[0116] Reference Figure 8 and Fig.12 As shown, the connecting plate 222 may be a U-shaped plate, for example, and the two ends of the opening of the U-shaped plate may be respectively connected to the top end surface of the annular sealing plate to form the above-mentioned ventilation gap 223 between the U-shaped plate and the inner cavity of the annular sealing plate.

[0117] In some embodiments, reference Figures 1 to 8 As shown, a lifting portion 5 for lifting is provided on the top sealing member 21. This arrangement facilitates the user to perform operations such as lifting and pressing the sealing structure 2 through the lifting portion 5, and is convenient to use.

[0118] In some embodiments, reference Figures 1 to 13 As shown, the top cover 12 has a downwardly recessed cavity 122 , and the first air outlet 121 is provided on the cavity wall of the cavity 122 . When the top sealing member 21 moves downward to cover the first air outlet 121 , the top surface of the top sealing member 21 does not protrude from the top edge of the top cover 12 .

[0119] In this way, when the top sealing member 21 covers the first air outlet 121, the entire air treatment device has a better appearance. At the same time, when the top sealing member 21 is provided with the lifting portion 5, it is possible to ensure the appearance of the air treatment device while facilitating the corresponding operation of the sealing structure 2 through the lifting portion 5 to adjust the air outlet direction of the air treatment device, which is convenient to use.

[0120] Specifically, for example, the bottom of the cavity wall of the cavity 122 may be recessed downward to form the aforementioned accommodation groove 123 .

[0121] In some embodiments, reference Figures 1 to 13 As shown, the first air outlet 121 is arranged to extend obliquely in the direction from the center of the concave cavity 122 to the edge of the concave cavity 122. In this way, when the first air outlet 121 is opened, the first air outlet 121 can guide the air to a certain extent, so that the air treated by the air treatment device can flow out from the first air outlet 121 in a timely and rapid manner, and the air flow rate is high, thereby improving the efficiency of air treatment to a certain extent.
