Description

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on June 5, 2024, with application number 2024107199490 and application name “A bag control method, system and intelligent trash can thereof”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of intelligent trash cans, and more particularly, to a bagging control method and system and an intelligent trash can thereof. Background Art

[0003] A smart trash can is a trash can that can automatically pack and change bags. It has an independent control module inside. By integrating some software control programs into the control module, it can realize intelligent control of the lid opening and closing function, packing function and bag changing function of the smart trash can, thereby realizing the intelligence of the smart trash can.

[0004] An existing Chinese invention patent, patent publication number CN108438612A, discloses a garbage bag laying device that uses a bag-laying fan to draw air and lay the bags. This suction creates a negative pressure inside the trash can, forcing the bags downward. The bag-laying fan begins operating when power is supplied, and the higher the supply voltage and the faster the fan speed, the better the suction performance and the higher the bag-laying completion rate. However, when the supply voltage to the bag-laying fan is low, the success rate of laying the garbage bags can be too low, affecting the user experience.

[0005] To improve the success rate of garbage bag laying, existing technologies typically require a relatively high power supply voltage for the bag laying blower. While this significantly improves the laying of some difficult-to-place garbage bags and ensures a near-100% success rate, it also accelerates battery power consumption within the smart trash can, reducing its battery life. Summary of the Invention

[0006] In response to the technical problem of how to extend the battery life of the product raised in the background technology, the present invention controls the working power of the bag-laying fan according to the remaining amount of the current garbage bags in the smart trash can. That is, when the remaining amount of the garbage bags decreases, the working power of the bag-laying fan is controlled to decrease. Therefore, compared with the situation in the prior art where the working power of the bag-laying fan remains unchanged, the technical solution of the present invention saves the power consumption of the smart trash can and improves the battery life of the product.

[0007] The present invention provides the following technical solution 1:

[0008] A bagging control method comprises the following steps:

[0009] A quantitative correspondence between a residual parameter of the garbage bags remaining in the garbage bag box and the operating power of the bag-laying fan is defined, and a qualitative correspondence between the two is that the smaller the residual parameter, the smaller the operating power;

[0010] Receive bag laying instructions from the user;

[0011] Get the remaining parameters of the garbage bags in the garbage bag box;

[0012] Selecting the operating power of the bag-laying blower corresponding to the margin parameter;

[0013] The bag-laying fan is controlled to complete the bag-laying operation under the selected working power conditions.

[0014] Through the above technical solution, the present invention controls the working power of the bag-laying fan according to the remaining amount of the current garbage bags in the smart trash can, that is, when the remaining amount of the garbage bags decreases, the working power of the bag-laying fan is controlled to decrease. Therefore, compared with the situation in the prior art where the working power of the bag-laying fan remains unchanged, the technical solution of the present invention saves the power consumption of the smart trash can and improves the product's endurance.

[0015] The present invention further comprises: after the bag laying fan starts to lay the bags, adding a garbage bag detection step to determine whether the garbage bags are laid;

[0016] If yes, the bag laying fan is controlled to cut off power in advance and stop working, and the bag laying is successful;

[0017] If not, determine whether the preset bag laying time is met;

[0018] If yes, the bag laying fan is controlled to cut off the power in advance and stop working, and the bag laying fails;

[0019] If not, the bagging fan continues to work.

[0020] The above technical solution adds a garbage bag detection step. After the bag-laying fan begins operating, the smart trash can begins to determine whether the garbage bag has been laid, thereby determining whether the laying of the garbage bag is successful or unsuccessful. If the garbage bag detection step is not added, the smart trash can controls the bag-laying time to be the preset bag-laying time. After the preset bag-laying time has passed, it is assumed that the bag laying is successful. When confirmation of bag laying is required, the smart trash can can only be manually opened to check. Furthermore, by adding the garbage bag detection step, the bag-laying fan can be controlled to stop operating in advance when the garbage bag laying is detected to be complete, further saving power consumption.

[0021] The present invention provides the following technical solution 2:

[0022] A bag making control system includes a bag making fan, a garbage bag remaining amount detection device, a controller and a power supply. The garbage bag remaining amount detection device is communicatively connected to the controller, the controller is control-connected to the bag making fan, the power supply and the bag making fan are electrically connected to supply power to the bag making fan, the controller is used to control the working power of the bag making fan, and the controller controls the bag making fan to operate under a working power condition corresponding to the remaining amount parameter of the garbage bag detected by the garbage bag remaining amount detection device. The corresponding relationship between the remaining amount parameter and the working power is that the smaller the remaining amount parameter, the smaller the working power.

[0023] Through the above technical solution, the garbage bag balance detection device of the present invention detects the remaining balance information of the garbage bag, and the controller controls the working power of the bag-laying fan according to the remaining balance information of the current garbage bag in the smart trash can, that is, when the remaining balance of the garbage bag decreases, the working power of the bag-laying fan is controlled to decrease. Therefore, compared with the situation in the prior art where the working power of the bag-laying fan remains unchanged, the technical solution of the present invention saves the power consumption of the smart trash can and improves the product's endurance.

[0024] The present invention further comprises a garbage bag detection device, which is used to detect the laying status of the garbage bag, and the garbage bag detection device is communicatively connected to the controller; when the garbage bag detection device detects that the laying of the garbage bag is completed, the controller controls the bag-laying fan to cut off the power and indicates that the bag-laying is successful; when the garbage bag detection device detects that the laying of the garbage bag is not completed, the controller further determines whether it is in a preset laying cycle, if so, the controller continues to control the bag-laying fan to work, if not, the controller controls the bag-laying fan to cut off the power and indicates that the bag-laying is unsuccessful.

[0025] The present invention further provides that: the garbage bag detection device is equipped with an infrared transmitter and an infrared receiver.

[0026] The above technical solution adds a garbage bag detection device. After the bag-laying fan begins operating, the smart trash can begins detecting whether the garbage bag has been laid, thereby determining whether the bag has been laid successfully or not. Without the garbage bag detection step, the smart trash can controls the bag-laying time to a preset time. After the preset time, it is assumed that the bag has been laid successfully. To confirm whether the bag has been laid, the smart trash can can only be manually opened to check. Furthermore, by adding the garbage bag detection step, the bag-laying fan can be stopped in advance upon detecting that the garbage bag has been laid, further saving power.

[0027] The present invention provides the following technical solution three:

[0028] A smart trash can applies the aforementioned bag spreading control method to control the bag spreading fan, or is equipped with the aforementioned bag spreading control system.

[0029] In summary, the present invention has the following beneficial effects:

[0030] (1) The present invention controls the operating power of the bag-laying fan according to the remaining amount of garbage bags in the smart trash can. That is, when the remaining amount of garbage bags decreases, the operating power of the bag-laying fan is controlled to decrease. Compared with the prior art in which the operating power of the bag-laying fan remains unchanged, the technical solution of the present invention saves the power consumption of the smart trash can and improves the endurance of the product.

[0031] (2) The present invention adds a garbage bag detection device, thereby being able to determine whether the garbage bag is laid successfully or unsuccessfully;

[0032] (3) By adding a garbage bag detection step, the present invention can also control the bag-laying fan to stop working in advance when it is detected that the garbage bags are laid, which can further save power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be further described in detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0038] like Figure 1 As shown, a bag laying control method of the present invention comprises the following steps:

[0039] (1) Define the quantitative relationship between the remaining parameters of garbage bags and the operating power of the fan. That is, define the quantitative correspondence between the remaining parameters of garbage bags in the garbage bag box and the operating power of the bag-laying fan. The quantitative correspondence refers to the correspondence between the specific value (or value range) of the remaining parameters and the specific value (or value range) of the operating power (see below). The qualitative correspondence between the two is positively correlated, that is, the smaller the remaining parameters, the smaller the operating power, and the larger the remaining parameters, the greater the operating power.

[0040] (2) Receive bag laying instructions from the user;

[0041] (3) Obtaining the remaining parameters of the garbage bags in the garbage bag box;

[0042] (4) Select the working power of the bagging fan corresponding to the margin parameter;

[0043] (5) Control the bag-laying fan to complete the bag-laying operation under the selected working power conditions.

[0044] The remainder parameter in step (1) of the above control method varies depending on the detection method of the garbage bag. The first implementation scheme is to determine the remainder parameter by detecting the weight of the garbage bag, that is, weighing the garbage bag box. When the garbage bags are used successively, the total weight of the garbage bag box gradually decreases. Therefore, in this implementation scheme, the remainder parameter is based on the weight parameter of the garbage bag box. The second implementation scheme is to infer the remaining number of uses of the garbage bag box by detecting the number of times the garbage bag is used (the number of times it is packed). Therefore, in this implementation scheme, the remainder parameter is the remaining number of uses. For example, a new garbage bag box can be estimated to be used 100 times. Each time the smart trash can packs a garbage bag, the remaining number of uses is reduced by one. The third implementation scheme is to determine the remaining length parameter by detecting the remaining length of the garbage bag. For example, the total length of the new garbage bag box is 5000 cm. The laying length is detected each time the garbage bag is laid, and the remaining length parameter can be obtained. Of course, other remainder parameters can also be used, and the purpose is to detect the remaining remainder of the garbage bag.

[0045] In the present invention, the remainder parameter is defined as a ratio parameter, that is, the ratio value of the remaining remainder divided by the total amount. The ratio method varies in different implementations. For example, when the remainder parameter is a remainder parameter based on the remaining weight of the garbage bag, the remainder parameter refers to the ratio parameter between the remaining weight of the garbage bag and the initial total weight of the garbage bag; when the remainder parameter is a remainder parameter based on the remaining number of garbage bags, the remainder parameter refers to the ratio parameter between the remaining number of garbage bags and the initial total number of garbage bags; when the remainder parameter is a remainder parameter based on the remaining length of the garbage bag, the remainder parameter refers to the ratio parameter between the remaining length of the garbage bag and the initial total length of the garbage bag.

[0046] In step (4) of the control method, the operating power of the bag-making blower is varied by varying the duty cycle of the power supply voltage within a power supply cycle, assuming the power supply voltage of the bag-making blower remains constant (assuming the power supply is 10V). Thus, the average power supply voltage within the power supply cycle can be varied, thereby varying the average operating power of the bag-making blower.

[0047] In one embodiment of the present invention, the corresponding relationship between the ratio parameter and the duty cycle ratio can be defined as:

[0048] When the ratio parameter is greater than or equal to 95%, the duty cycle of the supply voltage during the power supply cycle is 100%, and the average supply voltage during the power supply cycle is 10V. When the ratio parameter is greater than or equal to 80% and less than 95%, the duty cycle of the supply voltage during the power supply cycle is 85%, and the average supply voltage during the power supply cycle is 8.5V. When the ratio parameter is greater than or equal to 60% and less than 80%, the duty cycle of the supply voltage during the power supply cycle is 75%, and the average supply voltage during the power supply cycle is 7.5V. When the ratio parameter is greater than or equal to 50% and less than 60%, the duty cycle of the supply voltage during the power supply cycle is 70%, and the average supply voltage during the power supply cycle is 7.0V. When the ratio parameter is greater than or equal to 0 and less than 50%, the duty cycle of the supply voltage during the power supply cycle is 65%, and the average supply voltage during the power supply cycle is 6.5V.

[0049] In addition, in order to further save power consumption and accurately judge whether the bag laying is completed, the present invention Figure 2 As shown, the bag spreading control method of the present invention adds a garbage bag detection step after the bag spreading fan starts to spread the bags, that is, after the bag spreading fan starts to spread the bags, it is determined whether the garbage bags are laid;

[0050] If so, the bag laying fan is controlled to cut off power in advance and stop working, and the bag laying is successful.

[0051] If not, determine whether the preset bag laying time is met.

[0052] If so, the bag laying fan is controlled to cut off power in advance and stop working, and the bag laying fails.

[0053] If not, the bagging fan continues to work.

[0054] The above bagging control method needs to be based on a bagging control system as hardware support, such as Figure 3 As shown, the bag spreading control system includes a bag spreading blower 1, a garbage bag remaining amount detection device 2, a controller 3, and a power supply 4. The garbage bag remaining amount detection device 2 is communicatively connected to the controller 3, which is controllably connected to the bag spreading blower 1. The power supply 4 is electrically connected to the bag spreading blower 1 for supplying power to the bag spreading blower 1. The controller 3 is used to control the operating power of the bag spreading blower 1. The controller 3 controls the bag spreading blower 1 to operate under an operating power condition corresponding to a remaining amount parameter of the garbage bag remaining amount detected by the garbage bag remaining amount detection device 2. The corresponding relationship between the remaining amount parameter and the operating power is that the smaller the remaining amount parameter, the lower the operating power.

[0055] As mentioned above, I will not repeat it here. The margin parameter is actually a ratio parameter, and the change in operating power is actually to change the duty cycle of the power supply voltage during the power supply cycle, thereby changing the average power supply voltage during the power supply cycle, and then changing the operating power.

[0056] Therefore, the controller 3 controls the bagging blower 1 to operate under the corresponding operating power conditions. For example, when the ratio parameter is greater than or equal to 95%, the controller 3 controls the duty cycle of the bagging blower 1's supply voltage to 100% during the power cycle, and the average supply voltage during the power cycle is 10V. When the ratio parameter is greater than or equal to 80% and less than 95%, the controller 3 controls the duty cycle of the bagging blower 1's supply voltage to 85% during the power cycle, and the average supply voltage during the power cycle is 8.5V. When the ratio parameter is greater than or equal to 60% and less than 80%, the controller 3 controls the duty cycle of the bagging blower 1's supply voltage to 75% during the power cycle, and the average supply voltage during the power cycle is 7.5V. When the ratio parameter is greater than or equal to 50% and less than 60%, the controller 3 controls the duty cycle of the bagging blower 1's supply voltage to 70% during the power cycle, and the average supply voltage during the power cycle is 7.0V. When the ratio parameter is greater than or equal to 0 and less than 50%, the controller 3 controls the duty cycle of the power supply voltage of the bag-making blower 1 to be 65% during the power supply cycle, and the average power supply voltage during the power supply cycle is 6.5V.

[0057] To further conserve power and accurately determine bag laying completion, the bag laying control system of the present invention includes a garbage bag detection device 5 for detecting the bag laying status. The garbage bag detection device 5 is communicatively connected to the controller 3. When the garbage bag detection device 5 detects that the bag laying is complete, the controller 3 controls the bag laying blower 1 to power down and indicate successful bag laying. When the garbage bag detection device 5 detects that the bag laying is incomplete, the controller 3 further determines whether the bag laying cycle is within a preset cycle. If so, the controller 3 continues to control the bag laying blower 1; if not, the controller 3 controls the bag laying blower 1 to power down and indicates unsuccessful bag laying. The garbage bag detection device 4 is configured with an infrared transmitter and an infrared receiver. The garbage bag detection device 5 can be configured as a weight sensor, a counting sensor, or other device.

[0058] Finally, the present invention discloses an intelligent trash can, which applies the aforementioned bag laying control method to control the bag laying fan to achieve garbage bag laying. Alternatively, the intelligent trash can is configured with the aforementioned bag laying control system to control the bag laying fan to achieve garbage bag laying.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
