Description

Technical Field

[0001] This application relates to the field of cleaning, and more specifically, to a method for detecting the remaining amount of paper towels. Background Technology

[0002] Current tissue dispensers include center-pull tissue dispensers, which dispense tissues from the center of a roll. However, center-pull tissue dispensers are prone to center collapse during use, which can easily lead to false alarms in tissue status detection. Summary of the Invention

[0003] This application proposes a method for detecting the remaining amount of paper towels to solve the above-mentioned technical problems.

[0004] The above objectives are achieved through the following technical solutions in the embodiments of this application.

[0005] This application provides a method for detecting the remaining amount of tissue paper, applied to a center-flush tissue dispenser, characterized in that the method includes: A sensor and a central tissue are provided in the central tissue dispenser, and a predetermined distance is provided between the side ends of the sensor and the central tissue. Set the maximum detection distance of the sensor to the predetermined distance.

[0006] In one embodiment, the central tissue dispenser includes a housing with a first sidewall for securing the central tissue dispenser to an ambient space, and the sensor is disposed between the central tissue dispenser and the first sidewall.

[0007] In one embodiment, the sensor is positioned below.

[0008] In one embodiment, the predetermined distance is between 1cm and 2cm.

[0009] In one embodiment, the preferred distance of the predetermined distance is 1.3cm-1.5cm.

[0010] In one embodiment, the sensor is an infrared sensor.

[0011] In one embodiment, the sensor includes a first detection point, a second detection point, a third detection point, and a fourth detection point, which are arranged sequentially from top to bottom. When the first detection point is triggered, the central tissue box is full of tissues; when the second and third detection points are triggered, the central tissue box has tissues; when the fourth detection point is triggered, the central tissue box has few tissues; and when the fourth detection point is not triggered, the central tissue box is empty.

[0012] In one implementation, the central tissue box is determined to be in a paper-containing state only when the first detection point is triggered three times consecutively with a 50-second interval between each trigger.

[0013] In one implementation, the detection threshold of the first detection point is higher than the detection thresholds of the second, third, and fourth detection points.

[0014] In one embodiment, the detection threshold of the first detection point is 30% higher than the detection thresholds of the second, third, and fourth detection points.

[0015] Compared with existing technologies, this application provides a method for detecting the remaining amount of tissue paper. A sensor and a central tissue paper are installed in the center tissue dispenser, with a predetermined distance between the sensor and the side end of the central tissue paper. The maximum detection distance of the sensor is set to the predetermined distance. Using this method, even if the center tissue paper collapses during use, the usage status of the central tissue paper can be accurately determined. Attached Figure Description

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0023] Please see Figure 1 and Figure 2 This application provides a central tissue dispenser 100. Figure 1 The central tissue dispenser 100 conceals the front housing. The central tissue dispenser 100 includes a housing 1, which contains a central tissue 2. The housing 1 is provided with a paper outlet 3. The central tissue 2 is drawn out from the paper outlet 3. During the process of the central tissue 2 being drawn out, the tissue in the upper center will collapse downwards.

[0024] The center tissue dispenser 100 also includes a sensor 4, which is at a predetermined distance from the side end 21 of the center tissue 2. The maximum detection distance of the sensor 4 is set to this predetermined distance, so that even if the center tissue collapses during use, the usage status of the center tissue can be accurately determined, such as whether there is paper or no paper.

[0025] Sensor 4 has a transmitter and a receiver. Assuming the detection distance of sensor 4 is set to 3cm, and an obstruction is placed within this distance, for example, at a distance of 2cm, the signal emitted by the transmitter will be reflected by the obstruction and then received by the receiver, thus allowing the detection of the obstruction. However, if an obstruction is placed outside the detection distance, for example, at a distance of 4cm, it will not be detected because it is beyond the detection range.

[0026] Assuming the predetermined distance between sensor 4 and the side end 21 of the central tissue box 2 is 2cm, and the maximum detection distance of sensor 4 is also set to 2cm, even if the tissue box at the top center of the central tissue box 4 collapses downwards, sensor 4 will not detect the collapsed tissue box, so it can accurately determine whether the central tissue box has paper or not.

[0027] Understandably, the maximum detection distance of sensor 4 does not necessarily need to be precisely set to the predetermined distance between sensor 4 and the side end 21 of the central tissue 2. It can also have slight deviations, which do not affect the sensor 4's ability to sense the usage status of the central tissue.

[0028] In one embodiment, the housing 1 includes a first sidewall 11 for fixing the central tissue dispenser 100 in an environmental space, such as a toilet or kitchen. The sensor 4 is disposed between the central tissue dispenser 2 and the first sidewall 11. This arrangement can more accurately determine the usage status of the central tissue dispenser.

[0029] In one embodiment, sensor 4 is positioned below. Assuming the central tissue box 2 has a virtual center line, sensor 4 is positioned below the center line, which allows for more accurate determination of the tissue box's usage status.

[0030] In one embodiment, the predetermined distance between the sensor 4 and the side end 21 of the central tissue box 2 is set to 1cm-2cm. As the central tissue box 2 is gradually pulled out, the tissue in the upper center will collapse downwards. The extent of the collapse is uncertain. Sometimes the tissue in the upper center will slightly protrude towards the side end 21 of the central tissue box 2. After multiple tests, the predetermined distance between the sensor 4 and the side end 21 of the central tissue box 2 is set to 1cm-2cm, which allows the usage status of the central tissue box to be accurately determined regardless of where the tissue in the upper center of the central tissue box 4 collapses.

[0031] In one embodiment, the preferred distance between the sensor 4 and the side end 21 of the central tissue 2 is 1.3cm-1.5cm, which allows for a more accurate determination of the usage status of the central tissue 4 regardless of which direction the tissue at the top center collapses.

[0032] In one embodiment, sensor 4 is an infrared sensor. The infrared sensor has a transmitter and a receiver. The signal emitted by the transmitter is reflected by the obstruction and then received by the receiver, thereby enabling the determination that there is an obstruction.

[0033] In one embodiment, the sensor 4 includes a first detection point 41, a second detection point 42, a third detection point 43, and a fourth detection point 44, arranged sequentially from top to bottom. When the first detection point 41 is triggered, the signal emitted by the transmitter can be received by the receiver, and the central tissue box 2 is in a full state. When the second detection point 42 and the third detection point 43 are triggered, the central tissue box 2 is in a state with paper, but the remaining amount of paper is different. The remaining amount of paper detected at the second detection point 42 is higher than that detected at the third detection point 43. When the fourth detection point 44 is triggered, the central tissue box 2 is in a state with less paper. When the fourth detection point 44 is not triggered, the central tissue box 2 is in a state without paper.

[0034] In one implementation, the first detection point 41 is triggered three times consecutively with a 50-second interval between each trigger before the central tissue box 2 is determined to be in a paper-containing state. For example, the first detection point 41 is triggered at the 1st second, at the 51st second, and at the 101st second. This avoids the sensor 4 detecting collapsed tissue paper and allows for a more accurate determination of the paper-containing state at the center of the central tissue box 4, regardless of where the tissue paper at the top center of the central tissue box 4 collapses.

[0035] In one embodiment, the detection threshold of the first detection point 41 is higher than the detection thresholds of the second detection point 42, the third detection point 43, and the fourth detection point 44. This can further improve the accuracy of determining whether the central portion of the tissue box contains paper or not.

[0036] In one embodiment, the detection threshold of the first detection point 41 is 30% higher than the detection thresholds of the second detection point 42, the third detection point 43, and the fourth detection point 44.

[0037] In one implementation, such as Figure 3 and Figure 4 The tissue dispenser also includes roll paper dispenser 200 and stack paper dispenser 300. Roll paper dispenser 200 has roll paper 20, which gradually consumes tissue paper from the outer periphery of the roll paper 20 towards the center. Stack paper dispenser 300 has stack paper 30, which is stacked one sheet at a time from top to bottom. Sensor 4 can not only detect the center tissue dispenser 100, but also adaptively detect the roll paper dispenser 200 and the stack paper dispenser 300. That is, sensor 4 can adapt to the detection of the remaining tissue paper in the roll paper dispenser 200 and the stack paper dispenser 300.

[0038] When the tissue dispenser is the roll paper dispenser 200, the detection distance of the sensor 4 is adjusted to the first detection distance; when the tissue dispenser is the stacked paper dispenser 300, the detection distance of the sensor 4 is adjusted to the second detection distance; when the tissue dispenser is the center drawer dispenser 100, the detection distance of the sensor 4 is adjusted to the third detection distance, wherein the third detection distance is less than the first detection distance and the second detection distance.

[0039] As the central tissue box 2 is gradually drawn out, the tissue in the upper center will collapse downwards. This collapse can cause misjudgment of the remaining tissue. Even if the tissue in the center is used up, it can still lead to a false judgment that there is still tissue. However, the roll paper dispenser 200 and the stack paper dispenser 300 do not have the problem of the central tissue collapsing. Therefore, the third detection distance is set to be less than the first and second detection distances, so that the sensor 4 can adaptively sense the remaining tissue in the central tissue box dispenser 100, the roll paper dispenser 200, and the stack paper dispenser 300.
