The deodorizing and drying device 1000 is also used for spraying heated airflow to a human body in a drying working state, drying water stains on the human body and improving user experience.

[0048] Please refer to Figures 1 to 9 The application discloses a deodorizing and drying device 1000, which comprises a shell assembly 100, a fan 20, a deodorizing assembly 30 and a heating assembly 40. The shell assembly 100 can be integrally formed or spliced by multiple shell parts. The shell assembly 100 is formed with an air duct 10, a first air inlet 101, a second air inlet 102, a first air outlet 103 and a second air outlet 104 which are sequentially arranged along an air supply direction and communicate with the air duct 10.

[0049] The deodorizing component 30 is arranged in the air duct 10 and located between the first air inlet 101 and the second air inlet 102, and is used to treat the odor gas flowing through the deodorizing component 30, so that the odor of the air flow flowing through the deodorizing component 30 is reduced. The specific type of the deodorizing component 30 is not limited, for example, it can be used to absorb odor components by using filter material, or it can be used to treat odor components by using ionization method, etc. The heating component 40 is arranged in the air duct 10 and located between the first air outlet 103 and the second air outlet 104, and is used to heat the air flow flowing therethrough. The heating component 40 is also not limited, in an embodiment, it can be heated by using an electric heating wire. The valve component 50 is arranged in the housing component 100, and includes a first valve 51 arranged between the deodorizing component 30 and the second air inlet 102, and a second valve 52 arranged between the first air outlet 103 and the heating component 40, and is used to control the on-off of the air flow in the air duct 10.

[0050] In the present embodiment, the specific structure and on-off control mode of the first valve 51 and the second valve 52 are not limited, the second air inlet 102 and the first air outlet 103 have an on-off control component to control the on-off state of the second air inlet 102 and the first air outlet 103, and the specific structure and control mode of the on-off control component are also not limited. Please refer to Figures 3 to 5 , the deodorizing and drying device 1000 has a deodorizing working state in which the first valve 51, the first air inlet 101 and the first air outlet 103 are opened, and the second valve 52 and the second air inlet 102 are closed. Please refer to Figure 5 , Figure 5 The dashed arrows in the figure indicate the direction of air flow, in the deodorizing working state, the air flow flows from the first air inlet 101, flows through the deodorizing component 30, and after the odor components are effectively treated, the air flow flows out from the first air outlet 103. Please refer to Figures 6 to 8 , the deodorizing and drying device 1000 also has a drying working state in which the second valve 52, the second air inlet 102, and the second air outlet 104 are opened, and the first valve 51 and the first air outlet 103 are closed. Please refer to Figure 8 , Figure 8 The dashed arrows in the figure indicate the direction of air flow, in the deodorizing working state, the air flow flows from the first air inlet 101, flows through the deodorizing component 30, and after the odor components are effectively treated, the air flow flows out from the first air outlet 103. Please refer to

[0051] It can be understood that in the present embodiment, the first air inlet 101 and the second air outlet 104 can be always open, and the flow direction of the air flow is controlled only by the opening and closing of the first valve 51 and the second valve 52 in combination with the opening and closing of the second air inlet 102 and the first air outlet 103. The first air inlet 101 and the second air outlet 104 can also be provided with an opening and closing control assembly to control the opening and closing state thereof.

[0052] In the present embodiment, the deodorizing and drying functions share the fan 20 and part of the air duct 10, and the deodorizing and drying device 1000 is switched between the deodorizing state and the drying state by controlling the opening and closing state of the valve assembly 50 and the second air inlet 102 and the first air outlet 103. In the deodorizing working state, the air flow is completely isolated from the heating assembly 40 by the blocking of the second valve 52, and no humidity is brought to the heating assembly 40, thereby prolonging the service life of the heating assembly 40. In the drying working state, the air flow is completely separated from the deodorizing assembly 30 by the blocking of the first valve 51, and the air flow is not contaminated by the deodorizing assembly 30, so that the air flow flowing through the heating assembly 40 has no odor, thereby improving the user experience.

[0053] The way of controlling the second air inlet 102 and the first air outlet 103 can be various, for example, a separate air door is arranged at the second air inlet 102 and the first air outlet 103 respectively, or a movable air duct 10 is arranged to be connected to them. However, this arrangement is complex in structure, not only increases the production cost, but also is easy to cause improper cooperation in use, resulting in failure of the deodorizing and drying device 1000. In the preferred embodiment, please refer to Figures 2 to 8 , the shell assembly 100 includes a first shell 11 and a second shell 12 connected in sliding mode, the first shell 11 is provided with a first opening 111 and a second opening 112 arranged in sequence along the air supply direction, the second shell 12 is provided with a third opening 121 and a fourth opening 122 arranged in sequence along the air supply direction, in the relative sliding stroke of the first shell 11 and the second shell 12, the first opening 111 and the third opening 121, and the second opening 112 and the fourth opening 122 are staggered with each other or at least partially coincide with each other, the coinciding part of the first opening 111 and the third opening 121 constitutes the second air inlet 102, and the coinciding part of the second opening 112 and the fourth opening 122 constitutes the first air outlet 103. Specifically, please refer to Figure 5 , in the deodorizing working state, the first opening 111 and the third opening 121 are staggered, and the second opening 112 and the fourth opening 122 at least partially coincide with each other, so that the second air inlet 102 is closed and the first air outlet 103 is opened, and the air flow flowing into the air duct 10 flows out after flowing through the deodorizing module and the fan 20. In the drying working state, please refer toFigure 8 , the first opening 111 and the third opening 121 at least partially coincide, and the second opening 112 and the fourth opening 122 are staggered, so that the second air inlet 102 is opened, the first air outlet 103 is closed, and the airflow flowing into the air duct 10 flows out after passing through the fan 20 and the heating module.

[0054] In this embodiment, by sliding the first shell 11 and the second shell 12 relative to each other, the second air inlet 102 is controlled to open and close by the mutual coincidence or staggering of the first opening 111 and the third opening 121, and the first air outlet 103 is controlled to open and close by the mutual coincidence or staggering of the second opening 112 and the fourth opening 122. On the one hand, the structure is relatively simple, and the production cost is low. On the other hand, the opening and closing states of the second air inlet 102 and the first air outlet 103 are coordinated by the cooperation of the first shell 11 and the second shell 12, and the actions are synchronized, so that there is no coordination failure, and the deodorizing and drying device 1000 is avoided to be disabled.

[0055] Based on the previous embodiment, please continue to refer to Figure 2 , Figure 4 and Figure 7 . The valve assembly 50 is movably arranged in one of the first shell 11 and the second shell 12, and is in driving connection with the other one of the first shell 11 and the second shell 12, so that the first valve 51 and the second valve 52 switch the opening and closing states with the relative sliding of the first shell 11 and the second shell 12. In this embodiment, by linking the opening and closing actions of the valve assembly 50 with the sliding actions of the first shell 11 and the second shell 12, the opening and closing actions of the first valve 51 and the second valve 52 are linked with the opening and closing actions of the second air inlet 102 and the first air outlet 103, the opening and closing states are coordinated, and the actions are synchronized, so that there is no coordination failure, and the deodorizing and drying device 1000 is avoided to be disabled.

Please refer to Figure 9It can be seen that the second shell 12 provides a drying air flow when it is extended forward, and the outlet is closer to the human body, so the drying effect is better. It should be noted that in the present application, the upward and downward directions are generally parallel to the direction of gravity, the front and rear directions and the lateral directions are generally perpendicular to the upward and downward directions, and the front and rear directions and the lateral directions are perpendicular to each other, wherein the front and rear directions refer to the extension direction of the second shell 12.

In the present embodiment, it can be seen that the air duct 10 is arranged to have a bent shape, the air flow enters the first air duct section 110 and flows from front to back, flows to the second air duct section 120, and flows from back to front in the second air duct section 120, and finally flows out of the air duct 10. In this way, the first air inlet 101 and the second air outlet 104 are both located at the front end of the shell assembly 100, the first air inlet 101 is arranged downward and is closer to the odor source, and the second air outlet 104 is arranged upward and is closer to the human body, so that the deodorizing and drying effects of the deodorizing and drying device 1000 are better, and the power required for the operation of the fan 20 is also relatively reduced.

[0058] Please continue to refer to Figure 2 , Figure 4 and Figure 7 , the valve assembly 50 includes a rotating shaft 53 extending in the lateral direction, the rotating shaft 53 is rotatably installed in the first shell 11 and penetrates the baffle 60, the shaft section of the rotating shaft 53 located in the first air duct section 110 is fixedly connected with the first valve 51, the shaft section of the rotating shaft 53 located in the second air duct section 120 is fixedly connected with the second valve 52, the first valve 51 and the second valve 52 are arranged in a plate shape perpendicular to each other, so that the valve assembly 50 is switched between a first opening and closing state in which the first valve 51 is rotated to be opened and the second valve 52 is rotated to be closed, and a second opening and closing state in which the first valve 51 is rotated to be closed and the second valve 52 is rotated to be opened. In the present embodiment, the first valve 51 and the second valve 52 are connected together through the rotating shaft 53, and the opening and closing actions of the two are linked, so that when the first valve 51 is opened, the second valve 52 is closed, and when the first valve 51 is closed, the second valve 52 is opened, the actions of the two are linked, the states are coordinated, and there is no coordination failure, so that the deodorizing and drying device 1000 is not disabled.

[0059] In the preferred embodiment, in order to realize the linkage between the opening and closing states of the valve assembly 50 and the sliding action of the second shell 12, the second shell 12 is provided with a transmission member, and the rotating shaft 53 is provided with a transmission matching member, the transmission member and the transmission matching member are matched, and the rotating shaft 53 rotates in linkage with the sliding of the second shell 12, so as to switch the valve assembly 50 between the first opening and closing state and the second opening and closing state.

In this way, the first limiting protrusion and the second limiting protrusion play a role in limiting the closing positions of the first valve 51 and the second valve 52 on the one hand, so as to enhance the sealing performance of the first valve 51 and the second valve 52, and on the other hand, the buffer members play a role in correcting the position of the rotating shaft 53, so as to increase the fault tolerance of the cooperation between the transmission member and the transmission matching member and reduce the processing difficulty.

[0062] It can be understood that the above two embodiments can be implemented separately or in combination.

[0063] Please continue to refer to Figures 3 to 8, the first air inlet 101 is arranged on the first shell 11, and the second air outlet 104 is arranged on the second shell 12, the second shell 12 is sleeved on the front end of the first shell 11, and the front end is formed with a through hole extending along the front and back directions, in the drying working state, the second shell 12 covers the first air inlet 101, and in the deodorization working state, the first shell 11 extends out of the second shell 12 from the through hole, so that the first air inlet 101 is opened.
