The traditional soap dispenser does not have the ability to automatically detect the stock of soap, so it takes a lot of manpower to conduct inspections from time to time, resulting in waste of human resources and increased management costs; [0004] 2.

The soap dispenser liquid level sensing device 100' includes a capacitance sensing unit 10', a control unit 20', and a liquid level determiner 30'. The capacitance sensing unit 10' has a substrate 102' and a capacitance sensor 104' wired on the substrate 102'. The capacitance sensor 104' generates a capacitance value C'. The control unit 20' is electrically connected to the capacitance sensing unit 10', and receives the capacitance value C' of the capacitance sensor 104' to generate a capacitance conversion calculation value. In this embodiment, the capacitance conversion calculation value is A cycle count value Nos is taken as an example. The liquid level determiner 30' is electrically connected to the control unit 20' to receive the cycle count value Nos generated by the control unit 20', and is compared with a preset capacitance conversion calculation threshold. The capacitance conversion calculation critical value is an example of a period critical value, thereby generating at least one output control signal So. [0014] Please refer to the second figure, which is a circuit block diagram of the first embodiment of the liquid level sensing device for the soap dispenser. The soap dispenser liquid level sensing device 100' includes a capacitance sensing unit 10', a control unit 20', and a liquid level determiner 30'. The capacitance sensing unit 10' has a substrate 102' and the capacitance sensor 104' wired on the substrate 102', wherein the capacitance sensor 104' generates a capacitance value C'. Moreover, the electric 10021·^·single number A0101 page 5/total 31 page 1013009145-5-0 M424905 _^ 01/01/2011, the shuttle replacement page sensor 104' layout is set at the position of the substrate 102' Can be determined for a specific level sensing. That is, the capacitive sensor 104' can be disposed at a lower half of the substrate 102' to provide the liquid level sensing device 100' for the liquid level sensing; The capacitive sensor 104' can be disposed at an upper half of the substrate 102' for providing the liquid level sensing device 100' for the liquid level sensing, but not for The capacitive sensor 104' is provided with an elastic layout setting, depending on the actual application and needs. [0015] The at least one control unit 20' is electrically connected to the at least one capacitive sensing unit 10'. Each of the control units 20' includes an oscillator 204' and a counter 206'. The oscillator 204' is electrically coupled to the capacitive sensor 104' of the capacitive sensing unit 10' to receive the induced capacitance value C' and to generate an oscillating signal Sos in conjunction with a resistor Ros and a capacitor Cos. The counter 206' is electrically connected to the oscillator 204' to receive the oscillating signal Sos, and counts the oscillation period of the oscillating signal Sos, thereby generating a period count value Nos. Taking this embodiment as an example, when the Nos is less than or equal to the preset period threshold value Nth, it indicates that the liquid level of the soap liquid in the soap dispenser is normal, but if the Nos is greater than the preset period threshold When the value is Nth, it indicates that the liquid level of the soap liquid in the soap dispenser is insufficient, and the liquid level determiner 30' outputs a control signal So to perform a subsequent procedure such as warning. [0016] Referring to the fourth figure, it is a schematic diagram of the use of the capacitance sensing unit of the first embodiment of the liquid level sensing device for a soap dispenser. In the present embodiment, the soap dispenser liquid level sensing device 100' includes a capacitance sensing unit / 10'. The capacitance sensing unit 10' is attached to one side of the soaping machine. 1002 face 0 No. A 〇 101 Page 6 / Total 31 page 1013009145-0 M424905 _ January 01, 2011 Shuttle is replacing the page surface. As is clear from the fourth figure, the capacitance sensing unit 10 0 is attached to the height of one side of the outer surface of the soap container, and has a capacitance sensor 104 ′ for sensing the inside of the soap dispenser. The liquid level Ls of the soap liquid Lq is determined to determine whether the liquid level Ls of the soap liquid Lq in the soaping machine is too low. It is worth mentioning that the soap container is a non-conductive material container, such as glass or plastic material, so that when the capacitance sensing unit 10' is attached to the outer surface of one side of the soaping machine, the shielding can be avoided. The interference generated by the effect affects the sensing accuracy of the capacitive sensing unit 10'. In this embodiment, the capacitive sensor 104' is disposed at a lower half of the substrate 102' for providing the liquid level sensing device 100' for the liquid level sensing. . In addition, the capacitive sensor 1 0 4 ′ can also be disposed at an upper half of the substrate 102 ′ for providing the liquid level sensing device 100 ′ for the liquid level height sensing. . [0017] Referring to the third figure, it is a schematic diagram of the operation of the control unit of the first embodiment of the liquid level sensing device for the soap dispenser. When the soaping machine is filled with soap, and the liquid level Ls of the soap liquid Lq in the soaping machine is only below the set height of the capacitive sensor 104', the capacitive sensor 104' generates a The fixed sensing capacitor value C', therefore, the sensing capacitor value C' forms the equivalent capacitance value with the capacitor Cos of the oscillator 204', so that the oscillation signal Sos generated by the oscillator 204' has an oscillation period. Therefore, the counter 206' counts the cycle count value Nos generated by the oscillation signal Sos. Taking the illustration as an example, it is assumed that the counter 206' counts the cycle count value Nos as 155 times in the interval between the first time t1 and the second time t2; further, the liquid level determiner 30' The cycle count value Nos can be compared with a predetermined one cycle threshold value Nth.

In the present embodiment, the soap dispenser level sensing device 1 comprises an array type capacitance sensing unit 10.

The liquid level height is below the set height of the second capacitive sensor 104_2. In this embodiment, for example, since the cycle count value Nos (=140) is less than the preset period threshold value Nth (=145), the liquid level determiner 30 determines the liquid of the soap liquid Lq in the soap dispenser. The height of the surface Ls is equal to the set height of the second capacitive sensor 104_2 or above. [0025] In addition, the liquid level determiner 30 can generate at least one output control signal So to control an external display device, such as a light-emitting diode, a liquid crystal panel (LCD panel) or a sound device, etc. a functional device for indicating a warning of a low level or a low level of the liquid surface Ls of the soap liquid Lq in the soaping machine; or, when the liquid level Ls of the soap liquid Lq in the soaping machine is lower than a certain critical height, the system The soaping function of the soap dispenser will be automatically stopped, thereby reducing the waste of power resources and the abrasion of the soaping machine; even when the liquid level Ls of the soap liquid Lq in the soaping machine is lower than a certain critical height, the system This message will be automatically transmitted to the building control center, prompting the supervisor to immediately dispatch maintenance personnel to the soap replenishment operation, so as to effectively use human resources and avoid the situation that no soap is available for cleaning. [0026] Referring to FIG. 9 , it is a schematic diagram of the use of the array type capacitance sensing unit of the third embodiment of the liquid level sensing device of the present invention, wherein the calculation result of the capacitance conversion generated by the control unit 20 is Taking the cycle count value as an example, the preset capacitance conversion calculation threshold value of the liquid level determination unit 30 is exemplified by the cycle threshold value Nth. As shown in the ninth figure, the third embodiment and the aforementioned 1013009145-0 page 12 / 31 pages M424905 January 09, 101 nuclear replacement page The second embodiment (see the eighth figure with the greatest difference) In this embodiment, there are two array capacitive sensing units (a first array capacitive sensing unit 10 and a second array capacitive sensing unit 10). In this embodiment, the first array of capacitive sensing units 10 and the second array of capacitive sensing units 10 are respectively disposed on the one outer side surface and the other outer surface in a longitudinally spaced manner, that is, The first array type capacitive sensing unit 10 and the second array type capacitive sensing unit 10 are symmetrically attached at an interval of 180 degrees. Similarly, if the embodiment has three array-type capacitance sensing units, the array-type capacitive sensing units are symmetrically placed at an interval of 120 degrees in an equidistant manner. Moreover, each of the array type capacitive sensing units 10 is electrically connected to a control unit (not shown), and is respectively output through the corresponding multiplexer 202, the corresponding oscillator 204, and the corresponding counter 206 as described above. Two cycle count values Nos. In this way, by calculating the two cycle count values Nos by an arithmetic average operation or other numerical operations, such as interpolation (interpolation, extrapolation), etc., to obtain an average cycle count value, the accuracy can be obtained more accurately. The liquid level Ls of the soap liquid Lq in the soap machine is raised. It is worth mentioning that the main purpose of using multiple array capacitive sensing units (not limiting the above two array capacitive sensing units 10) is to provide an inevitable action (such as replenishing liquid) when using the soaping machine for human operation. Process) or the user accidentally collides, causing the soap liquid in the soap machine to sway, as shown in the figure IX, at a certain moment of shaking, the liquid level of the liquid is equal to the right side of the second array capacitor The sensing unit 10, at this time, is sensed to be lower than a low liquid level H- of a threshold liquid level Hth, so that the external display device will have a message that needs to be replenished (but in fact, this malfunctioning factor) Human error caused by the operation; and, the liquid level of the liquid is equal to the left side of the first array of capacitive sensing 1002 brain P number delete 1 page 13 / a total of 31 pages 1010309145-0 M424905 101 January 01 shuttle Replacing the page unit 10, at this time, it is sensed that it is higher than a high liquid level point H+ of a threshold liquid level Hth, so that no liquid needs to be replenished (in fact, the liquid level is still the wrong liquid) Bit information)The reverse is also true, and will not be repeated here. In short, both of the above cases result in an increased chance of malfunction of the soap dispenser level sensing device 100. Therefore, the present invention further proposes to utilize at least two of the array type capacitive sensing units 10, and cooperate with the two cycle count values Nos by an arithmetic average operation or other numerical operations, such as interpolation (interpolation, extrapolation). ... and so on, an average liquid level Havg is obtained, and thus, the actual liquid surface Ls height of the soap liquid Lq in the soaping machine can be obtained, and the misjudgment caused by the sloshing phenomenon of the soap liquid in the soaping machine can be avoided. [0027] Referring to the tenth figure, it is a schematic diagram of the use of the array type capacitive sensing unit of the fourth embodiment of the liquid level sensing device for soap dispensers. The difference between the fourth embodiment and the foregoing second embodiment (see FIG. 8 for the cooperation) is that the array type capacitive sensing unit 10 is installed in the interior of the soap dispenser (not with the soap). The liquid container is in contact with each other. Therefore, the array type capacitive sensing unit 10 further includes a waterproof insulating structure to provide the array type capacitive sensing unit 10 for sensing the liquid level Ls height of the soap liquid L q in the soaping machine. Waterproof insulation function while avoiding short circuit malfunction. In addition, since the array type capacitive sensing unit 10 is installed in the soap dispenser, the interference caused by the shielding effect does not affect the sensing accuracy of the array capacitive sensing unit 10. Therefore, the soap container is It may not be limited to a non-conductive material container, such as glass or plastic material, or a conductive material container. [0028] Referring to FIG. 11 , it is a schematic diagram of the use of the capacitance sensing unit of the fifth embodiment of the liquid level sensing device for a soap dispenser. The fifth embodiment and 10021928#single number A〇101 page 14/total 31 page 10103009145-0 M424905 January 01, 2011 correction replacement page The first difference of the first embodiment (see the fourth figure) is that the biggest difference lies in The capacitor sensing unit 10' is installed in the interior of the soaping machine (not in contact with the container containing the soap). Therefore, the capacitive sensing unit 10' further includes a waterproof insulating structure to provide The capacitance sensing unit 10' is used for sensing the waterproof insulation function of the liquid level Ls of the soap liquid Lq in the soap dispenser, and avoids short circuit malfunction. In addition, since the capacitance sensing unit 10' is installed in the soaping machine, the interference caused by the shielding effect does not affect the sensing accuracy of the capacitance sensing unit 10'. Therefore, the soap container is not limited. It is a non-conductive material container, such as glass or plastic material, and can also be a container of conductive material. [0029] In summary, the present invention has the following advantages: [0030] 1. When the liquid level Ls of the soap liquid Lq in the soaping machine is lower than a certain critical height, the system will automatically stop the soaping machine. The soap function is used to reduce the waste of electricity and power resources and the abrasion of the soaping machine, thereby further extending the service life. [0031] 2.
