[0034] Combine the following Figures 1 to 4 The detection device for preventing wall-mounted objects from falling of the present application is described.

[0035] See also Figures 1 to 4In a first aspect of the present application, a detection device for preventing a wall-mounted object from falling is provided, the detection device comprising a housing 1, a channel 2 disposed inside the housing 1, a ball 3 contained in the channel 2, a control panel 6, and a signal transmitting component 4, a signal receiving component 5, and an alarm component 7 respectively connected to the control panel 6. The channel 2 has a bend 22, so that the front portion 23 of the channel 2 is in a form of being low in front and high in the back, and the rear portion 21 of the channel 2 is in a form of being high in front and low in the back, and the positions of the signal transmitting component 4 and the signal receiving component 5 are arranged as follows:

[0036] In the first form, when the housing 1 is in a substantially horizontal position, the signal emitted by the signal emitting component 4 in a straight line can be received by the signal receiving component 5; and when the housing 1 is tilted together with the wall-mounted object and exceeds a certain angle, the ball 3 falls from the front end 24 of the channel 2 to the rear end 25 of the channel 2, thereby blocking the signal emitted by the signal emitting component 4 to the signal receiving component 5, so that the control board 6 controls the alarm component 7 to alarm; or, in the second form, when the housing 1 is in a substantially horizontal position, the ball 3 blocks the signal emitted by the signal emitting component 4 to the signal receiving component 5 in a straight line. When the housing 1 is tilted together with the wall-mounted object and exceeds a certain angle, the ball 3 rolls from the front end 24 of the channel 2 to the rear end 25 of the channel 2, thereby enabling the signal emitted by the signal emitting component 4 to be received by the signal receiving component 5, so that the control board 6 controls the alarm component 7 to alarm.

[0037] The present application provides a detection device for preventing wall-mounted objects from falling. When the wall-mounted object tilts or falls, the detection device will also tilt. At this time, the ball 3 inside the housing 1 will roll from the front end 24 of the channel 2 to the rear end 25 of the channel 2. The signal emitted by the signal transmitting component 4 is cut off by the ball 3. At this time, the signal receiving component 5 sends a signal to the control board 6. The control board 6 controls the alarm component 7 to sound an alarm according to the signal sent by the signal receiving component 5, so as to prompt the user that the wall-mounted object tilts and falls, thereby preventing the wall-mounted object from falling and injuring people.

[0038] Optionally, the signal transmitting component 4 is a light emitting component, preferably an LED light emitting diode. The signal receiving component 5 is a photosensitive component, preferably a phototransistor, a photoresistor or a photodiode, any one of which can be selected according to specific circumstances.

[0039] The signal emitted by the signal emitting component 4 may be light, and the signal receiving component 5 may be exposed to light.

[0040] See also Figures 1 to 4In the preferred embodiment of the above-mentioned wall-mounted object anti-fall detection device, the housing 1 is generally a rectangular body, preferably made of a light-shielding material, such as stainless steel, iron, black plastic, or a transparent plastic with a light-shielding film bonded to the outside to prevent external light sources from interfering with the signal receiving component 5. The channel 2 and the housing 1 are integrally formed, and the channel 2 is cylindrical in shape, which is convenient for the ball 3 to roll inside the channel 2. The control board 6 is fixed to the partition 81 of the housing 1 by screws and glue, and is placed in the interlayer 8. The control board 6 is respectively connected to the signal transmitting component 4, the signal receiving component 5 and the alarm component 7 through lines. It should be noted that the control board 6 is an existing conventional control board, which has a control program inside and can be connected to a home wireless network to achieve a communication connection.

[0041] See also Figures 1 to 4 As shown, in the preferred embodiment of the above-mentioned detection device for preventing wall-mounted objects from falling, one of the signal receiving component 5 and the signal emitting component 4 is arranged at the front end 24 of the channel 2, and the other is arranged near the rear end 25 of the channel 2. When the housing 1 is in a substantially horizontal position, the signal emitted by the signal emitting component 4 in a straight line can be received by the signal receiving component 5. When the housing 1 is tilted together with the wall-mounted object and exceeds a certain angle, the ball 3 rolls down from the front end 24 of the channel 2 to the rear end 25 of the channel 2, and thus blocks one of the signal receiving component 5 and the signal emitting component 4, so that the signal receiving component 5 cannot receive the signal emitted by the signal emitting component 4.

[0042] In this way, when the wall-mounted object exceeds a certain angle, the ball 3 can block the signal emitted by the signal emitting component 4. At this time, the signal receiving component 5 sends a signal to the control panel 6. After receiving the signal, the control panel 6 controls the alarm component 7 to alarm, so as to remind the user that the wall-mounted object is tilted and falls, thereby preventing the wall-mounted object from falling and injuring people.

[0043] See also Figure 1 and Figure 2 In the preferred embodiment of the above-mentioned detection device for preventing a wall-mounted object from falling, the signal receiving component 5 and the signal transmitting component 4 are coaxially arranged so that the signal receiving component 5 is located within the signal range of the signal transmitting component 4. By coaxially arranging the signal receiving component 5 and the signal transmitting component 4, the signal emitted by the signal transmitting component 4 can be directly irradiated onto the signal receiving component 5 to obtain sufficient signals, and the signal receiving component 5 can send signals to the control panel 6 in real time, that is, at this time, the wall-mounted object is in a stable state without tilting.

[0044] Optionally, the signal receiving component 5 and the signal transmitting component 4 may also be staggered and arranged in different axes, as long as it is ensured that the signal of the signal transmitting component 4 can be received by the signal receiving component 5 .

[0045] See also Figures 1 to 4As shown, in the preferred embodiment of the above-mentioned detection device for preventing wall-mounted objects from falling, one of the signal receiving component 5 and the signal transmitting component 4 is arranged at the rear end 25 of the channel 2, and the other is arranged at the front end 24 of the channel 2. When the housing 1 is in a substantially horizontal position, the ball 3 blocks one of the signal receiving component 5 and the signal transmitting component 4, so that the signal receiving component 5 cannot receive the signal emitted by the signal transmitting component 4 in a straight line. When the housing 1 is tilted together with the wall-mounted object by more than a certain angle, the ball 3 rolls down from the front end 24 of the channel 2 to the rear end 25 of the channel 2, and thus no longer blocks one of the signal receiving component 5 and the signal transmitting component 4, so that the signal receiving component 5 can receive the signal of the signal transmitting component 4.

[0046] In this way, when the wall-mounted object exceeds a certain angle, the ball 3 no longer blocks the signal emitting component 4. At this time, the signal receiving component 5 can receive the signal sent by the signal emitting component 4. At this time, the signal receiving component 5 sends a signal to the control panel 6. After receiving the signal, the control panel 6 controls the alarm component 7 to alarm, so as to remind the user that the wall-mounted object is tilted and falls, thereby preventing the wall-mounted object from falling and injuring people.

[0047] See also Figures 1 to 4 In the preferred embodiment of the above-mentioned wall-mounted object anti-falling detection device, the alarm component 7 generally includes a buzzer (not shown in the figure) and / or a light source (not shown in the figure) installed inside the housing 1 for prompting. The buzzer and the light source are provided to remind the user that the wall-mounted object is tilted and there is a risk of falling, so that the user can repair it in time.

[0048] Specifically, the buzzer and the light source are arranged inside the interlayer 8 and fixed to the inner wall of the housing 1 by glue or screws. A sound-transmitting hole is opened at the position of the housing 1 corresponding to the buzzer so that the sound of the buzzer can be transmitted more widely, and a light-shielding cloth is bonded to the sound-transmitting hole to prevent the external light source from irradiating the signal receiving component 5. A through hole is opened at the position of the housing 1 corresponding to the light source so that the light source extends to the outside of the through hole, and light-shielding glue is applied to the through hole to fix the light source while preventing the light source from irradiating the signal receiving component 5.

[0049] See also Figure 1 and Figure 2 In the preferred embodiment of the above-mentioned detection device for preventing the wall-mounted object from falling, the control board 6 is connected to the chip inside the socket connected to the wall-mounted object so as to cut off the power supply, and the control board 6 is also connected to the user's mobile phone for communication so as to prompt. When the wall-mounted object tilts or falls, the control board 6 sends a signal to the chip inside the socket to control the socket to cut off the power supply, thereby avoiding personal injury caused by leakage.

[0050] Specifically, the socket is an existing socket with a chip, and the control board 6 and the chip are connected through a signal to drive the socket to automatically power off.

[0051] See also Figures 1 to 4 As shown, in the preferred embodiment of the above-mentioned detection device for preventing wall-mounted objects from falling, the interior of the housing 1 is further provided with an interlayer 8, and the interlayer 8 includes a partition 81, which is arranged at the inner rear part of the housing 1, and the interlayer 8 is formed between the partition 81 and the inner rear part of the housing 1. Among them, the interior of the interlayer 8 is provided with one of the signal receiving component 5 and the signal transmitting component 4, as well as the alarm component 7 and the control board 6. The inner rear part of the housing 1 is separated into an interlayer 8 by the partition 81, which is used to install the signal receiving component 5, the alarm component 7 and the control board 6, so as to avoid the need to open more holes on the partition 81 to achieve line connection when the signal receiving component 5, the alarm component 7 and the control board 6 are installed at other positions of the housing 1, thereby reducing the signal receiving component 5 receiving the signal of the signal transmitting component 4 when it is not appropriate from time to time.

[0052] Optionally, the partition 81 and the housing 1 are integrally formed by a mold, and the shape of the partition 81 is consistent with the cross-sectional shape of the housing 1 to avoid the generation of gaps.

[0053] As an implementable embodiment, a battery compartment (not shown in the figure) is also installed inside the interlayer 8, and a replaceable battery (not shown in the figure) is installed inside the battery compartment. The battery compartment and the signal transmitting component 4, the signal receiving component 5, the control board 6, and the alarm component 7 are connected through lines to supply power.

[0054] It should be noted that the detection device for preventing wall-mounted objects from falling in the present application can be set inside the wall-mounted object, outside the wall-mounted body, or in the gap between the wall-mounted object and the wall. Those skilled in the art can determine it according to actual conditions.

[0055] Continue reading Figure 1 and Figure 2 In the preferred embodiment of the above-mentioned detection device for preventing a wall-mounted object from falling, the housing 1, both sides of the partition 81 and the outer surface of the channel 2 are all bonded with an opaque plastic film. By bonding the opaque plastic film on the partition 81 and the channel 2, it is avoided that when the ball 3 falls to the rear end 25 of the channel 2, the signal of the signal emitting component 4 cannot be transmitted, that is, the light is blocked, thereby preventing the signal emitting component 4 from being cut off from sending the signal to the signal receiving component 5.

[0056] Continue reading Figures 1 to 4In the preferred embodiment of the above-mentioned detection device for preventing wall-mounted objects from falling, a light-transmitting structure 9 is further provided inside the housing 1. The light-transmitting structure 9 generally includes a first through hole 91 and a second through hole 92. The first through hole 91 is provided on the partition 81 so that the signal receiving component 5 can abut against it. The second through hole 92 is provided on the side of the rear end 25 of the channel 2 and corresponds to the first through hole 91. The first through hole 91, the second through hole 92 and the signal emitting component 4 are coaxially arranged. By providing the first through hole 91 and the second through hole 92, the signal of the signal emitting component 4 can be directly received by the signal receiving component 5, which is conducive to completely cutting off the signal of the signal emitting component 4 when the ball 3 falls to the rear end 25 of the channel 2.

[0057] Specifically, the first through hole 91 is opened at the lower part of the partition 81, and the end of the signal receiving component 5 is inserted into the first through hole 91 for receiving the light from the emitting component 4. The diameter of the first through hole 91 is the same as the diameter of the end of the signal receiving component 5, so that the signal receiving component 5 can fully receive the signal of the signal emitting component 4.

[0058] Furthermore, the end of the signal receiving component 5 is not exposed outside the first through hole 91 to avoid being damaged by being hit by the ball 3 .

[0059] In this embodiment, the first through hole 91 and the second through hole 92 are generally circular holes, which can be the same shape as the end of the signal receiving component 5. The diameters of the first through hole 91 and the second through hole 92 are smaller than the diameter of the ball 3. In this way, when the ball 3 rolls to the rear end 25 of the channel 2, the signal of the signal transmitting component 4 can be completely cut off to avoid failure in cutting off the signal.

[0060] Continue reading Figures 1 to 4 In the preferred embodiment of the above-mentioned detection device for preventing wall-mounted objects from falling, the diameter of the ball 3 is equal to the cross-sectional diameter of the channel 2, and the diameter of the ball 3 is larger than the diameters of the first through hole 91 and the second through hole 91. In this way, the ball 3 rolls smoothly in the channel 2, avoiding the problem of jamming when the ball 3 rolls from the front end 24 of the channel 2 to the rear end 25 of the channel 2.

[0061] Continue reading Figure 1 and Figure 2 In a preferred embodiment of the above-mentioned wall-mounted object anti-fall detection device, the angle of the bend 22 is 5° to 45°, and preferably the angle of the bend 22 is 30°.

[0062] Specifically, the angle of the bend 22 is 5°. When the household appliance is slightly tilted, that is, the housing 1 is also slightly tilted, at this time, the ball 3 will roll from the front end 24 of the channel 2 to the rear end 25 of the channel 2 to cut off the signal of the signal transmitting component 4, and the signal will no longer be received by the signal receiving component 5. The sensitivity to the slight tilt of the wall-mounted object is high. The angle of the bend 22 is 45°. When the wall-mounted object is greatly tilted, that is, the housing 1 is also greatly tilted, at this time, the ball 3 will roll from the front end 24 of the channel 2 to the rear end 25 of the channel 2 to cut off the signal of the signal transmitting component 4, and the signal will no longer be received by the signal receiving component 5. The sensitivity to the large tilt of the wall-mounted object is high. The angle of the bend 22 is 30°. When the household appliance is moderately tilted, that is, the housing 1 is also moderately tilted, at this time, the ball 3 will roll from the front end 24 of the channel 2 to the rear end 25 of the channel 2 to cut off the signal of the signal transmitting component 4, and the signal will no longer be received by the signal receiving component 5. The sensitivity to the moderate tilt of the wall-mounted object is high.

[0063] In a second aspect, the present invention provides a household appliance, comprising the device for detecting anti-falling of wall-mounted objects as described in the first aspect.

[0064] The household appliance of this technical solution includes the detection device for preventing wall-mounted objects from falling of any technical solution of the present invention, and thus has all the technical effects of the detection device for preventing wall-mounted objects from falling of any technical solution of the present invention.

[0065] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
