[0037] The technical problem of poor steam exhaust effect of the drain hole exists in the prior art.

[0038] Therefore, the present application provides a lampshade, characterized in that it comprises:

[0039] a cover body, the cover body has a containing cavity opening to one side, the containing cavity is used for containing a lighting device, and the containing cavity has a real-time pressure;

[0040] a steam outlet hole, the steam outlet hole penetrates through the cover body and communicates with the containing cavity;

[0041] a one-way valve, the one-way valve is arranged in the steam outlet hole, two ends of the one-way valve in a first direction are respectively provided with a steam inlet and a steam outlet, the steam inlet is arranged in the containing cavity, the steam outlet is arranged outside the cover body, and the one-way valve has a rated pressure; wherein

[0042] when the real-time pressure is greater than the rated pressure, the water vapor in the containing cavity is discharged by the one-way valve.

[0043] Embodiment 1:

[0044] Please refer to the drawings Figure 2 and the drawings Figure 3 , the first direction X is the height direction of the lampshade, that is, the up-down direction of the lampshade, the top of the cover body 100 is up, the bottom of the cover body 100 is down, and the first direction X in the present application can be the direction from the bottom of the cover body 100 to the top of the cover body 100, or the direction from the top of the cover body 100 to the bottom of the cover body 100. The second direction Y is the width direction of the one-way valve 200, that is, the left-right direction of the one-way valve 200, and the second direction Y in the present application can be the direction from the left side of the one-way valve 200 to the right side of the one-way valve 200, or the direction from the right side of the one-way valve 200 to the left side of the one-way valve 200.

[0045] the drawings Figure 1 is a structural diagram of the cover body 100 of the present application. Please refer to the drawings Figure 1As shown, the lampshade of the present application comprises a cover body 100, which is used to cover the lighting device to achieve protection of the lighting device. The cover body 100 has a containing cavity 110 opening to one side, which is used to contain the lighting device. Further, the lighting device enters the containing cavity 110 through the opening.

[0046] In an embodiment, the lighting device is a light bulb.

[0047] In the present application, the lighting device will increase the temperature in the containing cavity 110 under the lighting condition, and further provide the air pressure in the containing cavity 110. At this time, the air pressure in the containing cavity 110 is the real-time air pressure, which changes in real time according to the illumination of the lighting device and the illumination of natural light.

[0048] Specifically, the real-time air pressure when the lighting device is on is higher than that when the lighting device is off. The sunlight on a sunny day is stronger than that on a cloudy day, so the real-time air pressure on a sunny day is higher than that on a cloudy day.

[0049] Please refer to Figure 1 As shown, the cover body 100 of the present application comprises a main light area 120 and a side light area 130. The difference between the main light area 120 and the side light area 130 is that the main light area 120 is arranged corresponding to the lighting device, and the main light area 120 is arranged in the illumination direction of the lighting device, so the main light area 120 receives the main light from the lighting device, and the lighting ability of the lighting device depends on the amount of light passing through the main light area 120. The side light area 130 is arranged at the bottom of the main light area 120, and the side light area 130 is around the electrical connection of the lighting device, so the amount of light passing through the lighting device is much less than that of the main light area 120. The one-way valve 200 is arranged on the side light area 130, thereby reducing the influence of the one-way valve 200 on the lighting ability of the lighting device.

[0050] In an embodiment, the one-way valve 200 is arranged at the bottom of the side light area 130 in the first direction X, in this state, the one-way valve 200 forms an inverted state to avoid the external water vapor or moisture remaining in the one-way valve 200.

[0051] Please refer to the accompanying Figure 1 As shown, the cover body 100 of the present application further comprises a mechanical connecting piece 150, and the cover body 100 is connected with the base through the mechanical connecting piece 150, thereby achieving the closure of the opening of the containing cavity 110. Thus, the containing cavity 110 is ensured to be in a relatively closed space, and further avoids the external water vapor entering the cover body 100. Although the relative closure of the containing cavity 110 can be achieved after the base is arranged, the external water vapor can still enter the containing cavity 110 when the lighting device is replaced or when driving on a bumpy road.

[0052] In an embodiment, the mechanical connector 150 is a clamping block, and the cover 100 is connected to the base by clamping.

[0053] Please refer to the attached Figure 1 The cover 100 of the present application also includes a steam outlet hole 160, which is used to set a one-way valve 200 to discharge the steam in the containing cavity 110.

[0055] In an embodiment, the boss 140 is a cuboid structure.

[0056] The attached Figure 2 is a front view of the lamp cover of the present application. Please refer to the attached Figure 2 The boss 140 includes an inner protrusion 141 and an outer protrusion 142, and the inner protrusion 141 and the outer protrusion 142 are fixedly connected.

[0058] Please refer to the attached Figure 2 The lamp cover of the present application also includes a one-way valve 200, which is set in the steam outlet hole 160. The one-way valve 200 is set with a rated pressure, which can be selected according to different lamp covers. When the real-time pressure in the containing cavity 110 is greater than the rated pressure in the one-way valve 200, the steam in the containing cavity 110 is discharged by the one-way valve 200.

[0059] In an embodiment, the one-way valve 200 and the steam outlet hole 160 are in interference fit.

[0060] In an embodiment, the rated pressure is greater than the standard atmospheric pressure.

Please refer to the attached Figure 3As shown, the one-way valve 200 comprises a through hole 230, the through hole 230 comprises a first through hole 231, an intermediate through hole 232 and a second through hole 233 arranged in sequence along the first direction X, the intermediate through hole 232 is connected with the first through hole 231 and the second through hole 233 respectively, the intermediate through hole 232 forms a stepped hole with the first through hole 231 and the second through hole 233 respectively, the cross-sectional area of the intermediate through hole 232 is greater than the cross-sectional area of the first through hole 231 and the second through hole 233, the steam inlet 210 is arranged on the first through hole 231, and the steam outlet 220 is arranged on the second through hole 233. Further, the steam inlet 210 is located in the accommodation cavity, and the steam outlet is located outside the cover body.

[0062] In an embodiment, the second through hole 233 comprises an inner through hole 233-1 and an outer through hole 233-2, the first end of the inner through hole 233-1 is connected with the intermediate through hole 232, the second end of the inner through hole 233-1 is connected with the outer through hole 233-2, the steam outlet 220 is arranged on the outer through hole 233-2, and the cross-sectional area of the inner through hole 233-1 is greater than the cross-sectional area of the outer through hole 233-2 to form a step.

[0063] In an embodiment, any cross section of the through hole 230 is circular or rectangular.

[0064] Please refer to the accompanying drawings Figure 3 As shown, the one-way valve 200 further comprises a blocking piece 240, the maximum cross-sectional area of the blocking piece 240 is greater than the cross-sectional area of the first through hole 231 and the second through hole 233, the maximum cross-sectional area of the blocking piece 240 is smaller than the cross-sectional area of the intermediate through hole 232, the blocking piece 240 floats up and down in the intermediate through hole 232 along the first direction X, the blocking piece 240 is arranged close to the first through hole 231, and the blocking piece 240 can block the first through hole 231 when the blocking piece 240 abuts against the first through hole 231.

[0065] In an embodiment, the cross section of the blocking piece 240 is circular or rectangular.

[0066] Please refer to the accompanying drawings Figure 3 As shown, the one-way valve 200 further comprises a resilient piece 250 arranged along the first direction X, the first end of the resilient piece 250 abuts against the bottom of the blocking piece 240, and the second end of the resilient piece 250 abuts against the step in the second through hole 233.

[0067] In an embodiment, the resilient piece 250 is a spring or other elastic object.

[0068] Please refer to the accompanying drawings Figure 3As shown, the one-way valve 200 of the present application further comprises an air film 260, the air film 260 is arranged in the outer through hole 233-2, the air film 260 is arranged horizontally along the second direction Y, and the air film 260 is provided with a crack. The air film 260 can realize the state change of the air film 260 breaking and the air film 260 closing according to the change of the real-time pressure due to the existence of the crack. When the air film 260 breaks, due to the existence of the crack, when the real-time air pressure is less than the rated air pressure, the breaking of the air film 260 can be restored to the closing of the air film 260. Because the air film 260 is only opened when the water vapor is outputted outward, and when the water vapor is outputted outward, the output pressure exists in the steam outlet 220, therefore the external water vapor is not easy to enter the second through hole 233. When the air film 260 does not output water vapor to the outside, the air film 260 is in the closed state, and the external water vapor cannot enter the second through hole 233, so as to further avoid that the external water vapor enters the containing cavity 110 through the one-way valve 200.

[0069] In an embodiment, the air film 260 is made of an elastic material.

[0070] In specific work, if the real-time pressure in the containing cavity 110 is greater than the rated pressure of the one-way valve 200, the water vapor pressure in the one-way valve 200 pushes the blocking piece 240 to move downward and compresses the elastic piece 250, so as to open the first through hole 231, the water vapor in the containing cavity passes through the first through hole 231, the intermediate through hole 232 and the second through hole 233 in turn, and the crack of the air film 260 is broken to form the breaking of the air film 260, and finally the water vapor in the containing cavity 110 is discharged. If the real-time pressure in the containing cavity 110 is less than the rated pressure of the one-way valve 200, the elastic piece 250 will push the blocking piece 240 upward and block the first through hole 231, so as to cut off the connection between the containing cavity 110 and the outside.
