The panel assembly 100 is disposed on the housing 300 for a user to perform corresponding control operations on the air purifier.

Referring to fig. 2 to 4, fig. 2 is a schematic structural view of a panel assembly of the air purifier shown in fig. 1, fig. 3 is a top view of the panel assembly shown in fig. 2, and fig. 4 is a sectional view of the panel assembly shown in fig. 3 along a direction a-a. The panel assembly 100 may include a case 11, a control panel 12, a light source 13, and a first light guide plate 14. The housing 11 includes a bottom wall 111 and a side wall 112 disposed around the bottom wall 111, the bottom wall 111 and the side wall 112 enclose to form a mounting cavity 113, an opening of the mounting cavity 113 is located at an end of the housing 11 away from the bottom wall 111, or the opening of the mounting cavity 113 is disposed upward as shown in fig. 4. The sidewall 112 has a light transmissive region 114 and a light opaque region such that light can be directed through the sidewall 112 through the light transmissive region 114 of the sidewall 112. The control panel 12 is connected to the side wall 112, and the control panel 12 closes the opening of the installation cavity 113. The light source 13 is disposed in the mounting cavity 113, and the light source 13 is located on one side of the control panel 12 facing the bottom wall 111, so that the light emitted from the light source 13 can be limited from exiting from the opening of the mounting cavity 113 through the control panel 12. The first light guide plate 14 is disposed between the control panel 12 and the bottom wall 111. And at least a part of the light incident surface of the first light guide plate 14 faces the light source 13, so that the emergent light of the light source 13 can enter the first light guide plate 14 through the light incident surface of the first light guide plate 14. At this time, at least a part of the light emitting surface of the first light guide plate 14 faces the light transmitting region 114, so that the light emitted from the light source 13 into the first light guide plate 14 can finally be emitted through the light transmitting region 114.

On one hand, the light of the light source 13 is incident on the first light guide plate 14 and then emitted, so that the emergent light emitted by the light source 13 and finally emitted from the light-transmitting region 114 is softer and more uniform, the appearance of the user is better, and the probability that the eyes of the user feel uncomfortable due to stimulation caused by local over-brightness of the emergent light of the light source 13 can be reduced.

On the other hand, when the user operates the control panel 12, the user's eyes usually look at the control panel 12, and the light emitted from the light source 13 is emitted from the light-transmitting region 114 on the sidewall 112. Or, the user's eyes are seen along the upward and downward inclined direction shown in the figure, and the outgoing light of the panel assembly is emitted from the horizontal direction, so the panel assembly 100 of the embodiment of the present application can reduce the probability that the user's eyes are directly irradiated by the outgoing light of the light source 13 to a certain extent, thereby reducing the probability that the user's eyes feel uncomfortable due to stimulation.

Illustratively, in conjunction with fig. 1, a side of the housing 11 of the panel assembly 100 facing away from the base 200 may be provided with a mounting structure. For example, the top of the housing 300 is provided with a mounting groove, and an opening of the mounting groove extends from the top end surface of the housing 300 to the outer side wall 112. At this time, the housing 300 of the panel assembly 100 may be inserted into the mounting groove and fixed to the housing 300. Wherein, the control panel 12 is located on one side of the bottom wall 111 opposite to the base 200, or the control panel 12 is disposed upward; accordingly, the light-transmitting region 114 of the housing 11 faces horizontally.

As shown in fig. 4, the control panel 12 may include a circuit board 121 and keys 122. The circuit board 121 is connected to the inner wall, such as the circuit board 121 is directly fixed on the side wall 112, or the circuit board 121 is indirectly fixed on the side wall 112 through other components. The circuit board 121 may also be connected to the bottom wall 111, such as a screw stud disposed on the bottom wall 111 for screw fastening the circuit board 121, which is not limited in the embodiment of the present application. The key 122 is disposed on a side of the circuit board 121 opposite to the bottom wall 111 and electrically connected to the circuit board 121, so that the key 122 can be disposed upward, thereby facilitating a user to perform a corresponding touch operation.

As shown in fig. 4, the control panel 12 may further include a light shield 123. The light shield 123 covers the circuit board 121 and is located on a side of the circuit board 121 opposite to the bottom wall 111. A peripheral annular flange 115 may be formed on the side wall 112 and the outer edge of the light shield 123 may be superposed on the annular flange 115. Furthermore, the light shield 123 can further prevent the light of the light source 13 from being emitted through the circuit board 121 and/or the gap between the circuit board 121 and the sidewall 112, i.e. the control panel 12 is not subject to light leakage and the like, so that the control panel 12 has better appearance. Of course, the light shield 123 has an accommodating hole 124, and the key 122 is disposed through the accommodating hole 124, so that the user can operate the key 122 conveniently.

As shown in fig. 4, in order to improve the aesthetic appearance of the panel assembly 100, the control panel 12 may further include a cover 125 disposed on a side of the light shield 123 opposite to the circuit board 121, wherein the cover 125 closes the receiving hole 124, so that the surface of the control panel 12 has no opening, and is more aesthetic. The cover 125 may be made of a material having a certain elastic deformation capability, so that when the user presses the cover 125, the cover 125 may find a certain amount of elastic deformation, so that the user can indirectly press the key 122.

Of course, in some embodiments, a touch screen or a touch capacitive switch may be used instead of the above-mentioned key 122, and the side of the circuit board 121 opposite to the bottom wall 111 is provided.

With continued reference to fig. 5 and 6, fig. 5 is an enlarged view of a portion of the panel assembly shown in fig. 4 at X, and fig. 6 is an exploded view of the panel assembly shown in fig. 2. The light source 13 is disposed on a side of the circuit board 121 facing the bottom wall 111, and the light source 13 is electrically connected to the circuit board 121. For example, the light source 13 may be one or more LED beads disposed on the circuit board 121. The light source 13 may be used as an atmosphere lamp, or may be used to indicate the operating state of the control panel 12 or the fan 400, or may be used to indicate the operating state of a sterilization device such as an ultraviolet lamp, a plasma emitter, a negative ion emitter, etc. disposed inside the air purifier, which is not limited in this embodiment of the present application.

The first light guide plate 14 may be made of transparent PC (Polycarbonate), so that it has the advantages of high light transmittance and easy production.

As shown in fig. 5, the light incident surface of the first light guide plate 14 may include a first surface 141. The first surface 141 is located on a side of the light source 13 facing the bottom wall 111, or the light source 13, the first surface 141, and the bottom wall 111 are arranged in sequence along an axial direction (an up-down direction in fig. 5) of the mounting cavity 113. When the light emitted from the light source 13 enters the first light guide plate 14, the light can propagate in the first light guide plate 14 along the radial direction (horizontal direction in fig. 5) of the mounting cavity 113, and finally, the light emitted from the light source 13 exits the housing 11 after passing through the light exit surface of the first light guide plate 14 to the light transmissive region 114.

As shown in fig. 5, the light incident surface of the first light guide plate 14 may also include a second surface 142. The second surface 142 is located between the light source 13 and the light-transmitting region 114. When the light emitted from the light source 13 enters the first light guide plate 14, the light can propagate in the first light guide plate 14 along the radial direction (horizontal direction in fig. 5) of the mounting cavity 113, and finally, the light emitted from the light source 13 exits the housing 11 after passing through the light exit surface of the first light guide plate 14 to the light transmissive region 114.

According to the internal spatial layout of the mounting cavity 113, the light incident surface of the first light guide plate 14 may include only the first surface 141, only the second surface 142, or both the first surface 141 and the second surface 142. The technical solution of the embodiment of the present application is further explained and explained by taking the light incident surface of the first light guide plate 14 as an example, that is, the light incident surface includes the first surface 141 and the second surface 142.

As shown in fig. 5, the first light guide plate 14 may include a horizontal portion 143 and a vertical portion 144. The horizontal portion 143 is substantially perpendicular to the side wall 112. Alternatively, the horizontal portion 143 is substantially parallel to the bottom wall 111. The horizontal portion 143 is located between the light source 13 and the bottom wall 111, and a surface of the horizontal portion 143 facing the light source 13 serves as the first surface 141. The vertical portion 144 may be substantially vertically disposed to the horizontal portion 143. The vertical portion 144 is located between the light source 13 and the light-transmitting area 114 of the sidewall 112 to block the light source 13 from the light-transmitting area 114 of the sidewall 112. At this time, a side of the vertical portion 144 facing the light source 13 serves as the second surface 142, and a side of the vertical portion 144 facing the light transmission region 114 serves as a light emitting surface of the first light guide plate 14.

In order to make the light emitted from the light source 13 exit the housing 11 through the light exit surface of the first light guide plate 14, the orthographic projection of the vertical portion 144 on the side wall 112 covers the light transmission region 114. Accordingly, a side surface of the vertical portion 144 facing away from the light source 13 is used as a light emitting surface, and an orthographic projection of the light emitting surface on the sidewall 112 also covers the light transmitting area 114, so that the light emitted from the light transmitting area 114 of the housing 11 is uniform and soft.

As shown in fig. 5, in order to improve the light extraction efficiency of the light source 13, the first light guide plate 14 is provided with a reflective layer 16 on a side facing the bottom wall 111, or the horizontal portion 143 is provided with a reflective layer 16 on a side facing the bottom wall 111. Specifically, the reflective layer 16 may be a silver reflective film attached to the horizontal portion 143, or a white ink layer printed on the horizontal portion 143, which is not limited in this embodiment. It can be understood that, in the process of the outgoing light of the light source 13 propagating and diffusing in the horizontal portion 143 along the radial direction (horizontal direction in fig. 5) of the mounting cavity 113, the outgoing light emitted from the horizontal portion 143 toward one side surface of the bottom wall 111 can be reflected back into the horizontal portion 143 by the reflective layer 16, so that the loss of the outgoing light of the light source 13 can be reduced to improve the light extraction efficiency of the light source 13.

As shown in fig. 2 or fig. 6, the housing 11 may be made of an opaque material, and the sidewall 112 is provided with a notch to form a light-transmitting region 114.

Illustratively, the housing 11 includes a bottom shell 116 and an aluminum ring 117. The bottom case 116 has a bottom plate forming the bottom wall 111 and side plates disposed around the bottom plate. The aluminum ring 117 is an annular structure made of aluminum. The aluminum ring 117 is sleeved on the side plate, and the aluminum ring 117 and the side plate are surrounded to form the side wall 112. The side plate and/or the aluminum ring 117 are provided with the above-mentioned notches to form the light-transmitting region 114.

As shown in fig. 4, the panel assembly 100 may further include a second light guide plate 15, and the second light guide plate 15 closes the gap. At least a part of the light incident surface of the second light guide plate 15 faces the light emergent surface of the first light guide plate 14, so that the emergent light emitted from the first light guide plate 14 can be incident into the second light guide plate 15. At least a part of the light emitting surface of the second light guide plate 15 is exposed, so that the emitted light entering the second light guide plate 15 can be emitted out of the housing 11. It can be understood that, by providing the second light guide plate 15, the emergent light of the light source 13 finally emitted out of the housing 11 can be further made softer and more uniform.

For example, as shown in fig. 5, the second light guide plate 15 may include a light guide part 151 and a fixing part 152. The light guide portion 151 is configured to guide the outgoing light emitted from the first light guide plate 14 to the outside of the case 11. The fixing portion 152 is used to be connected and fixed to the housing 11. For example, the fixing portion 152 may be directly connected with the housing 11. Alternatively, the fixing portion 152 may be connected to other components in the mounting cavity 113, and then connected to the housing 11 by the components, so as to realize indirect connection between the fixing portion 152 and the housing 11.

In some embodiments, as shown in fig. 5, light guide 151 is embedded in the notch to close the notch. A surface of the light guide part 151 away from the mounting cavity 113 (or an outer surface of the light guide part 151) may serve as a light exit surface of the second light guide plate 15. At this time, the outer surface of the light guide part 151 may be flush with the outer surface of the housing 11, so that the appearance surface of the control panel 12 is more flat and beautiful. A surface of the light guide part 151 on a side facing the axis of the mounting cavity 113 (or an inner surface of the light guide part 151) may serve as a light entrance surface of the second light guide plate 15.

As shown in fig. 5, the fixing portion 152 is connected to the light guide portion 151. The fixing portion 152 is interposed between the first light guide plate 14 and the bottom wall 111. Furthermore, the horizontal portion 143 of the first light guide plate 14 can be matched with the bottom wall 111 to clamp the fixing portion 152, and at this time, a mutually matched positioning structure can be further disposed between the fixing portion 152 and the bottom wall 111 for positioning, such as a positioning hole disposed on the fixing portion 152, and a positioning column inserted into the positioning hole disposed on the bottom wall 111. The first light guide plate 14 is clamped and fixed to the bottom wall 111. For example, the bottom wall 111 is provided with a claw 118, so that the bottom wall 111 is fastened to the horizontal portion 143 of the first light guide plate 14 by the claw 118.

The second light guide plate 15 may be made of transparent PC (Polycarbonate), so that it has the advantages of high light transmittance and easy production.

Of course, the bottom wall 111, the fixing portion 152 of the second light guide plate 15, the horizontal portion 143 of the first light guide plate 14, the circuit board 121, and the light shield 123 may be screwed and fixed at the same time, which is not limited in the embodiment of the present application.
