Detailed Description
The present invention will now be described with reference to the accompanying drawings, which are shown by way of example, and not by way of limitation.
Referring to fig. 1 to 5, an electronic candle 100 of the present invention includes a support 101, a flame shape element 102, a sensing element 103, a control circuit 104, and a light emitting element 105. The flame-shaped element 102, the sensor element 103, the control circuit 104, and the light-emitting element 105 are disposed on the support 101. The term "on" of the support 101 herein refers to being directly or indirectly mounted on the support 101, i.e., directly or indirectly attached to the support 101, and not referring to an upper direction, including but not limited to, the flame shape element 102, the sensing element 103, the control circuit 104, and/or the light emitting element 105 may be disposed on an inner surface, an outer surface, an upper surface, or a lower surface of the support 101, or in an interior space on the support 101 through other components. The sensing element 103 is used for receiving external input, converting the received external input into an electric signal and inputting the electric signal into the control circuit 104; the control circuit 104 is configured to output a control signal according to the number n of consecutive effective waveforms in the electrical signal, where the effective waveforms are waveforms of a single period that satisfy a predetermined condition; the light emitting element 105 is configured to receive a control signal and control the light delivered to the flame shaped element based on the control signal.
The electronic candle 100 according to the present invention, wherein the sensing element 103 processes and converts the collected external input into an electrical signal, and the control circuit 104 analyzes and processes the electrical signal therein. Different from the prior art and the related technology, other input sources which possibly cause misjudgment, such as signals generated by speaking voice or sudden vibration, are discriminated according to the number of continuous effective waveforms in the electric signals, so that the possibility of misjudgment in the prior art is greatly reduced, and the normal work and the interestingness of the electronic candle are ensured. The valid waveform, i.e., the single waveform that the control circuit recognizes as corresponding to the insufflation input, whether the valid waveform is formed depends on whether the single waveform satisfies a predetermined condition, which may be related to waveform parameters, for example, whether the waveform parameters include any one or a combination of a high level length h, a low level length l, a frequency f, a waveform peak value m of the single periodic waveform is a predetermined value or within a predetermined range, and whether sudden vibration causes instantaneous power failure to power the power supply.
In one embodiment of the present invention, the control circuit 104 of the electronic candle 100 further comprises a low voltage detection unit (not shown) for detecting the voltage level received by the control circuit 104 from the power supply, and the meeting of the predetermined condition comprises that the output of the low voltage detection unit is at a high level at the time corresponding to the single periodic waveform, and/or that the value of any one or the combination of the high level length h, the low level length l, the frequency f, and the waveform peak value m of the single periodic waveform is a corresponding predetermined value or is within a predetermined range. The low voltage detection unit is used to detect the actual power supply condition of the power supply of the electronic candle 100 to the control circuit 104, for example, when the power supply is low, the low voltage detection unit outputs a low level, and when the actual power supply provided by the power supply to the interior of the electronic candle is substantially equal to the power supply voltage, the low voltage detection unit outputs a high level. In the embodiment of the present invention, the low voltage detection circuit may detect whether the external input is external vibration, and when the external input is external vibration, the voltage actually supplied to the control circuit 104 by the power source of the electronic candle 100 oscillates accordingly, thereby generating a momentary low level, which the low voltage detection unit detects. In addition, in the embodiment of the invention, only the electric signal waveform which can possibly coincide with the blowing airflow can satisfy the predetermined condition, and belongs to the effective waveform, and the electric signal waveform which does not coincide with the blowing airflow is not considered to satisfy the predetermined condition and not belong to the effective waveform.
In an embodiment of the present invention, the output of the low voltage detection unit and/or any one or a combination of specific waveform parameters, such as the high level length h, the low level length l, the frequency f, and the waveform peak m, may be selected to distinguish the effective waveforms, so as to perform more accurate identification, so as to solve the problem of accurate identification to be solved by the present invention. In another preferred embodiment of the present invention, the output of the low voltage detection unit, the low level length l and the high level length h are simultaneously selected as the basis for analysis, so that more accurate recognition can be achieved. The invention is based on the multi-dimensional and multi-angle quantitative analysis and judgment, thereby furthest reducing the possibility of misjudgment of the electronic candle when the candle is extinguished by using a blowing mode.
According to a preferred embodiment of the invention, the support 101 of the invention is hollow or semi-hollow, and the flame shape element 102, the sensing element 103, the control circuit 104, and the light emitting element 105 are disposed on the support 101. The flame-shaped element 102 and the support 101 simulate the shape of a candle, but the invention is not limited thereto, and the flame-shaped element 102 may be a sheet, or in another embodiment, may be a three-dimensional structure, with a sharp upper portion, a circular cross-section with a certain radius in the middle portion, and a circular cross-section with a gradually decreasing radius in the lower portion. The shape of the supporting portion 101 may be a cylinder, a cylinder with a cross section of a triangle, a quadrangle, and other polygons, a truncated cone, a special shape with a certain curved or bent shape, and the like. The flame-shaped element 102 may be arranged on the support 101 by means of a rigid or flexible support part, and the sensing element 103, the control circuit 104, the light-emitting element 105 may be arranged directly on the support 101, one or more of which may also be arranged on the support 101 by means of a bracket. The light emitting element 105 may be arranged in the inner or outer space of the support 101 to be able to transmit light to the flame shaped element 102. The sensing element 103 is preferably disposed on the upper surface of the support 101 near the flame-shaped element 102, or in an airflow collecting cavity (not shown) on the support 101 to capture the airflow blowing the candle, and the sensing element 103 may be embodied in a form including, but not limited to, a microphone, or a microphone capable of converting an external input into an electrical signal. The control circuit 104 may be disposed in an inner or outer space of the support 101, and in a preferred embodiment, the control circuit 104 is disposed in an inner space of the support 101. The control circuit 104 is used for controlling and processing the whole electronic candle 100, and in one embodiment of the present invention, it may be a PCB (printed circuit board) board, in which different circuit units may be contained, for example, in one embodiment, a low voltage processing unit and/or a micro control unit is contained in the control circuit 104, and in another embodiment of the present invention, the control circuit 104 may also be an integrated chip, which integrates all the units/modules and components that may be contained in the control circuit 104 of the present invention together to fully utilize space and integrate processing.
In a preferred embodiment of the present invention, the control circuit 104 further includes an effective waveform determining unit (not shown) for determining whether the single periodic waveform is an effective waveform and outputting a determination result, if the output of the low voltage detecting unit is at a low level, the determination result is that the corresponding single waveform is an ineffective waveform, if the output of the low voltage detecting unit is at a high level, the control circuit further determines whether the high level length h of the single periodic waveform and the low level length l of the single periodic waveform are respectively a corresponding predetermined value or within a predetermined range, if both the high level length h and the low level length l are respectively a corresponding predetermined value or within a predetermined range, the control circuit determines that the single periodic waveform is an effective waveform, otherwise, the control circuit determines that the single periodic waveform is an ineffective waveform. Based on above-mentioned effective waveform judging unit, can discern whether external input is the vibration fast, promoted judgement efficiency. When the output of the low-voltage detection unit is at a low level, the waveform of the electric signal is considered to be caused by external vibration, and the external input is not blowing air flow, so that whether the waveform parameter meets a preset condition is not judged any more, and only when the output of the low-voltage detection unit is at a high level, the waveform parameter is detected again, for example, the length h of the high level and the length l of the low level are detected, and whether the waveform is an effective waveform is judged. Therefore, the detection mode avoids the workload increase and the efficiency reduction which are possibly brought by simultaneously detecting all judgment bases.
In a preferred embodiment of the present invention, the control circuit 104 comprises a counter, and referring to fig. 5, the control circuit 105 outputting the control signal according to the number of consecutive active waveforms in the electrical signal comprises: setting an initial value of a counter, wherein the counter performs counting operation when the waveform detected by the control circuit 104 is an effective waveform, and restores the current value of the counter to the initial value when the waveform detected by the control circuit 104 is an ineffective waveform; and when the current value of the counter meets the set condition, outputting the control signal to enable the light-emitting element 105 to generate corresponding action, otherwise, when the current value of the counter does not meet the set condition, continuing to judge the waveform of the next period. In the embodiment of the present invention, the initial value of the counter may be set to zero, or may be set to another value to facilitate counting. In another embodiment of the present invention, the counting operation may be set to be one or other number of values, and the condition that the current value of the counter needs to satisfy may be set according to the accuracy requirement for accurately identifying the electronic candle, for example, the number of the continuous effective waveforms may be set to be greater than or equal to 5 or 10, or if there is a higher requirement for accuracy, the number of the continuous effective waveforms may be set to be greater than or equal to 15, and then the control signal is sent out to make the light emitting element 105 generate the corresponding action. In one embodiment of the present invention, different conditions may be set to correspond to different actions of the candle, for example, different conditions may be set to cause the electronic candle to perform any one or combination of actions including, but not limited to, extinguishing, blinking at different speeds/directions, extinguishing after blinking, returning to a normally lit state after blinking, and the like.
In a preferred embodiment of the invention, wherein the low level length l of the effective waveform is set in the range of [1.5ms,10ms ], the advantage of setting such a range is that it is possible to accurately distinguish the blowing air flow from external inputs of sound, vibration, etc. in the waveform parameters. In another preferred embodiment of the present invention, the high level length h of the effective waveform is set in the range of [2ms,300ms ], which is advantageous in that the range can avoid the influence of the interference wave in the high level while enhancing the sensitivity of the remote blowing. In another preferred embodiment of the present invention, when the number n of consecutive effective waveforms is a positive integer greater than or equal to 5, the control circuit outputs a control signal to cause the light emitting element to operate accordingly. In a preferred embodiment, n is a positive integer greater than or equal to 15, i.e., the number of consecutive active waveforms is set to be greater than or equal to 15 before the control signal is output. In the above-described embodiments, such an arrangement may allow the electronic candle to more accurately recognize the blow-up airflow input, thereby properly actuating the light-emitting element 105 without similarly reacting to other inputs.
According to another preferred embodiment of the invention, the control circuit 104 of the invention comprises a memory for storing at least one of the conditions that the low level length l, the high level length h and the number n of consecutive active waveforms of said active waveform should satisfy. In another preferred embodiment, the memory is a programmable memory to enable a user to change and/or increase or decrease at least one of the conditions stored therein that should be satisfied including the low level length l, the high level length h, and the number n of consecutive active waveforms of the active waveform. The memory of the present invention is a programmable memory including, but not limited to, PROM, EPROM, EEPROM and/or flash memory, whereby the set conditions stored therein may be altered by the user to meet different accuracy requirements.
The invention also provides a control method of the electronic candle, wherein the electronic candle comprises a support part 101, a flame-shaped element 102, a light-emitting element 103, a sensing element 104 and a control circuit 105, wherein the flame-shaped element 102, the light-emitting element 103, the sensing element 104 and the control circuit 105 are arranged on the support part 101; the control method comprises the following steps: inputting an external input into the sensing element 103, wherein the sensing element 103 converts the received external input into an electric signal and inputs the electric signal into the control circuit 104; the control circuit 104 outputs a control signal according to the number n of continuous effective waveforms in the electric signal, wherein the effective waveforms are waveforms of a single period meeting a preset condition; the light emitting element 105 receives the control signal and controls the light delivered to the flame shaped element in accordance with the control signal.

Unlike the prior art and the related art, the control circuit 104 of the electronic candle of the present invention discriminates other input sources that may cause erroneous determination, such as signals generated by speaking sounds or sudden vibrations, according to the number of consecutive effective waveforms in the electrical signal, thereby greatly reducing the possibility of erroneous determination encountered in the prior art and ensuring the normal operation and interest of the electronic candle. The valid waveform, i.e., the single waveform that the control circuit recognizes as corresponding to the insufflation input, whether the valid waveform is formed depends on whether the single waveform satisfies a predetermined condition, which may be related to waveform parameters, for example, whether the waveform parameters include any one or a combination of a high level length h, a low level length l, a frequency f, a waveform peak value m of the single periodic waveform is a predetermined value or within a predetermined range, and whether sudden vibration causes instantaneous power failure to power the power supply.

The low voltage detection unit is used to detect the actual power supply condition of the power supply of the electronic candle 100 to the control circuit 104 thereof, for example, when the power supply is low, the low voltage detection unit outputs a low level, and when the actual power supply provided by the power supply to the interior thereof is substantially equal to the power supply voltage, the low voltage detection unit outputs a high level. In the embodiment of the present invention, the low voltage detection circuit may detect whether the external input is external vibration, and when the external input is external vibration, the voltage actually supplied to the control circuit 104 by the power source of the electronic candle 100 oscillates accordingly, thereby generating a momentary low level, which the low voltage detection unit detects. In addition, in the embodiment of the invention, only the electric signal waveform which can possibly coincide with the blowing airflow can satisfy the predetermined condition, and belongs to the effective waveform, and the electric signal waveform which does not coincide with the blowing airflow is not considered to satisfy the predetermined condition and not belong to the effective waveform.
In an embodiment of the present invention, the output of the low voltage detection unit and/or any one or a combination of specific waveform parameters, such as the high level length h, the low level length l, the frequency f, and the waveform peak m, may be selected to distinguish the effective waveforms, so as to perform more accurate identification, so as to solve the problem of accurate identification to be solved by the present invention. In another preferred embodiment of the present invention, the output of the low voltage detection unit, the low level length l and the high level length h are simultaneously selected as the basis for analysis, so that more accurate recognition can be achieved. The invention is based on the multi-dimensional and multi-angle quantitative analysis and judgment, thereby furthest reducing the possibility of misjudgment of the electronic candle when the candle is extinguished by using a blowing mode.
