[0034] Before this, it needs to be explained that, in order to facilitate the description, and in order to enable the person skilled in the art to quickly understand the technical solutions of the present application, the following text only describes the technical features which are relatively strong (directly related or indirectly related) in connection with the technical problems and / or technical concepts to be solved by the present application, and does not further describe the technical features which are relatively weak in connection with the technical problems and / or technical concepts to be solved by the present application. Since the technical features which are relatively weak in connection belong to the common knowledge in the art, the present application will not lead to insufficient disclosure even if it does not describe the relatively weak features.

[0035] As shown in Figure 1 and Figure 2 , in the first embodiment of the present application, the garbage can 100 of the present application can sterilize the garbage in the garbage can 100 to avoid the bacteria breeding in the can due to the long storage time of the garbage. The garbage can 100 includes a lid 1, a body 2, a weighing device 3, a sterilizing agent spraying module 4, a fan 5 and a controller 6. The weighing device 3 is arranged on the body 2 and is used to detect the garbage information of the garbage put by the user. The sterilizing agent spraying module 4 is arranged on the lid 1 and is used to release sterilizing agent to sterilize the garbage in the garbage can 100. The fan 5 is arranged on the lid 1 to perform fresh air treatment in the garbage can 100, so that the garbage can 100 does not produce unpleasant odor at the moment when the user opens the garbage can 100.

[0036] As shown in Figure 1 , the lid 1 is arranged above the body 2 and is used to close the garbage can 100. The lid 1 can be arranged on one side of the front part of the body 2 by hinging, so that the lid 1 can open and close the garbage can 100 by pivoting. The lid 1 includes a switch 11, a ventilation port 12 and an exhaust port 13.

[0037] Continuing to refer to Figure 1 , the switch 11 is arranged on the front side of the garbage can 100. When the user needs to open the lid 1, the switch 11 can be pressed to open the lid 1 of the garbage can 100.

[0038] Continuing to refer to Figure 1 , the ventilation port 12 penetrates the lid 1 of the garbage can 100. One end of the ventilation port 12 communicates with the inside of the garbage can 100, and the other end communicates with the outside air. The ventilation port 12 is used to guide the outside air into the garbage can 100.

[0039] Continuing to refer to Figure 1The exhaust port 13 penetrates the lid 1 of the garbage can 100, and is used to exhaust the gas in the garbage can 100 to the outside of the garbage can 100. Preferably, the exhaust port 13 is arranged on the side of the lid 1 of the garbage can 100 away from the ventilation port 12, so as to avoid the problem that the wind just blown out of the exhaust port 13 of the garbage can 100 is introduced into the garbage can 100 through the ventilation port 12, and the fresh air effect of the garbage can 100 is poor. Of course, the person skilled in the art can arrange the exhaust port 13 on the rear wall of the barrel body 2 of the garbage can 100 away from the exhaust port 13 according to the needs. Specifically, the exhaust port 13 is arranged at the position of the rear wall of the barrel body 2 close to the lid 1 of the garbage can 100, so as to avoid that the exhaust port 13 is blocked by the garbage in the garbage can 100, and the fresh air effect cannot be achieved.

[0040] Further, although not shown in the figure, in the second embodiment of the present application, the person skilled in the art can also arrange a damper (not shown in the figure) at the exhaust port 13 according to the needs, which is used to guide the air in the garbage can 100 to the outside of the garbage can 100. Preferably, the damper is a one-way damper, so that the air passing through the exhaust port 13 is only unidirectionally guided out of the garbage can 100.

[0041] Continuing to refer to Figure 1 The weighing device 3 is arranged at the bottom of the garbage can 100, and is used to weigh the garbage in the garbage can 100. The weighing device 3 comprises a weighing disc 31 and a weighing sensor 32. The weighing disc 31 is used to hold the garbage thrown by the user, and the weighing sensor 32 is arranged below the weighing disc 31, and is used to weigh the garbage on the weighing disc 31.

[0042] Continuing to refer to Figure 1 The sterilizing agent spraying module 4 is arranged on the inner side of the lid 1 of the garbage can 100, and is used to spray the sterilizing agent into the garbage can 100 to sterilize the garbage can 100. The sterilizing agent spraying module 4 comprises a sterilizing agent spraying port 41, a sterilizing agent and a driving pump. The sterilizing agent spraying port 41 is arranged on the inner side of the lid 1 of the garbage can 100, and is used to spray the sterilizing agent in the sterilizing agent spraying module 4 into the garbage can 100. The sterilizing agent comprises a sterilizing substance and a deodorizing substance. The driving pump is used to drive the sterilizing agent spraying module 4 to spray the sterilizing agent, wherein the driving pump can be arranged as an electric pump or a gas pump, and the driving principle of the driving pump has been disclosed in the prior art, which will not be described here.

[0043] Further, the form of the sterilizing agent can be aerosol or liquid. Specifically, the driving pump sprays the sterilizing agent in the form of liquid, such as atomization. Preferably, the driving pump sprays the sterilizing agent in the form of aerosol in the present application, and the aerosol-shaped sterilizing agent can adhere to the surface of the garbage, so that the sterilization of the garbage in the barrel is more sufficient.

[0044] As Figure 1 andFigure 2 As shown, the fan 5 is arranged on the lid 1 of the garbage can 100, and a ventilation hole is arranged below the fan 5 for air supply into the garbage can 100. Specifically, the fan 5 can be configured to be started after sterilization in the garbage can 100 is completed, so that external air can enter the garbage can 100 through the ventilation hole 12, and the air in the garbage can 100 is discharged to the outside of the garbage can 100 through the exhaust hole 13, so as to realize the fresh air function of the garbage can 100, and thus when the user opens the garbage can 100, the garbage can 100 will not produce a pungent smell. Further, the fan 5 can also be configured to be started when the sterilizing agent is put into the garbage can 100, and the fan 5 rotates at a set speed change frequency, so that the fan 5 provides the garbage can 100 with air waves with high and low pressure changes, so as to make the air waves vibrate the sterilizing agent and the garbage in the garbage can 100, and thus accelerate the penetration of the sterilizing agent to the garbage.

[0045] The control method of the garbage can 100 of the present application will be described in detail below Figures 3 to 5 in combination with the sterilization mode of the garbage can 100.

[0046] As shown in the first embodiment of the present application, the control method of the garbage can 100 includes: Figure 3

[0047] In step S110, the current weight of the garbage in the garbage can 100 is obtained. The weighing device 3 is configured to detect the weight of the garbage in the garbage can 100 and send the detected weight of the garbage to the controller 6, so that the controller 6 determines whether sterilization in the garbage can 100 is needed.

[0048] In step S120, it is determined whether the current weight reaches a preset threshold. When the current weight of the garbage reaches the preset threshold, it means that the garbage in the garbage can 100 is more, and the sterilizing agent spraying module 4 can sterilize the garbage in the can; when the current weight of the garbage in the garbage can 100 does not reach the preset threshold, it means that the garbage in the garbage can 100 is less, and the garbage can 100 does not need to be sterilized. At this time, the number of weight values detected by the weighing device 3 is recorded, and when the current weight of the garbage in the garbage can 100 is detected again and does not reach the preset threshold, the number of weight values recorded in the previous time is added, until the weighing device 3 detects that the current weight of the garbage in the garbage can 100 reaches the preset threshold, the final number of weight values is obtained, and the specific spraying amount of the sterilizing agent is obtained according to the number of weight values.

[0049] In step S130, if it is reached, the sterilizing agent spraying module 4 sprays the sterilizing agent to sterilize the garbage. According to the spraying amount of the sterilizing agent obtained, the sterilizing agent spraying module 4 releases the sterilizing agent to start the sterilization mode of the garbage can 100. ​

[0050] As Figure 4 shown in the first embodiment of the present application, the control method for determining the sterilizing agent spraying amount by the garbage can 100 comprises:

[0051] Step S210, the current weight of the garbage in the garbage can 100 is obtained.

[0052] Step S220, it is judged whether the current weight reaches the preset threshold value.

[0053] Step S230, if the current weight is less than or equal to the preset threshold value, the number of weight values detected by the weighing sensor 32 is recorded. Each time the weight in the garbage can 100 changes (i.e. each time the user puts garbage into the garbage can 100) and the current weight of the garbage in the garbage can 100 does not reach the preset threshold value, the number of weight values of the garbage in the garbage can 100 is recorded (i.e. the number of times the user puts garbage is recorded), and when the current weight of the garbage in the garbage can 100 is detected again and the current weight of the garbage in the garbage can 100 does not reach the preset threshold value, the number of weight values recorded last time is added, until the weighing device 3 detects that the current weight of the garbage in the garbage can 100 reaches the preset threshold value.

[0054] Step S240, if the current weight is greater than the preset threshold value, the number of weight values of the garbage detected by the weighing device 3 is obtained.

[0055] Step S250, the sterilizing agent spraying amount is determined according to the number of weight values. Wherein, the sterilizing agent spraying amount is determined according to the number of weight values, assuming that the number of weight values is n, the garbage can 100 can allow the user to put garbage at most 10 times, the sterilizing agent releasing amount of the sterilizing agent spraying module 4 is 5ml each time, and the final sterilizing agent releasing amount of the garbage can 100 is

[0056] Step S260, the sterilizing agent spraying module 4 sprays the sterilizing agent with the spraying amount, the weight value is cleared, and the user is reminded that the sterilization is in progress and not to open. After the sterilizing agent spraying amount is determined, the controller 6 controls the sterilizing agent spraying module 4 to release a certain spraying amount of sterilizing agent. At the same time, the number of weight values is cleared in order to record the spraying amount of the sterilizing agent next time, and the user is reminded that the garbage can 100 is in sterilization, so as to avoid opening the garbage can 100 during the sterilization process, so that the sterilizing agent is scattered to the air and causes unnecessary waste.

[0057] As Figure 5 shown in the first embodiment of the present application, after step S260, the following steps are included:

[0058] Step S261, while the sterilizing agent spraying module 4 sprays the sterilizing agent, the fan 5 is controlled to rotate at a set rotating speed and frequency conversion, so that the fan 5 provides the garbage can 100 with air waves with high and low pressure conversion, so that the air waves vibrate the sterilizing agent and the garbage, and further accelerate the penetration of the sterilizing agent to the garbage.

[0059] Step S262, after the sterilizing agent spraying is completed, the fan 5 is controlled to stop running.

[0060] Step S263, the garbage can 100 is left for a period of time.

[0061] Step S264, it is judged whether the sterilizing agent spraying module 4 stops working for a preset time length. After the sterilizing agent spraying module stops working, the sterilizing agent still floats in the air and has not completely settled. When the sterilizing agent spraying module stops working for the preset time length, it is judged that the sterilizing agent has completely settled and adsorbed on the garbage in the garbage can, that is, the garbage can sterilization mode is completed; when the sterilizing agent spraying module stops working for a time length that does not reach the preset time length, it is judged that the sterilizing agent has not completely settled, and the garbage can is left and the working time length of the sterilizing agent spraying module is detected.

[0062] Step S265, if it is reached, the fan 5 is controlled to run to discharge the air in the garbage can 100 to the outside of the garbage can 100; if it is not reached, step S263 is executed.

[0063] Step S266, in the process of the fan 5 running, the fragrance sprayer sprays the fragrance.

[0064] Step S267, the fan 5 is controlled to stop running, and the user is reminded that the sterilization is completed and the garbage can 100 is cleaned in time.

[0065] In the third embodiment of the application, the upper part of the garbage can 100 is further provided with a display screen for displaying prompt information to the user. Of course, the skilled in the art can remind the user to clean the garbage through voice reminder, vibration reminder or short message reminder.

[0066] In the fourth embodiment of the application, the switch 11 is arranged on the display screen, and the switch 11 can be a touch switch 11. When the user has something in his hand and is not convenient, he can directly touch the switch 11 to open the garbage can 100.

[0067] In the fifth embodiment of the present invention, an indicator light (not shown in the figure) is provided on the trash can 100. The indicator light is used to indicate whether the trash can 100 is in a sterilization state. Specifically, the indicator light can indicate whether the trash can 100 is in sterilization processing mode or whether the trash can 100 has completed sterilization by being lit or not. When the trash can 100 starts sterilization, the indicator light is lit to indicate to the user that sterilization is in progress inside the trash can 100; when sterilization is completed inside the trash can 100, the indicator light is turned off to indicate to the user that sterilization is complete inside the trash can 100 and the user can clean the trash can 100. Alternatively, those skilled in the art can set the indicator light to different colors as needed so that the user can distinguish the sterilization status inside the trash can 100. More specifically, a red indicator light indicates that sterilization is in progress inside the trash can 100; a yellow indicator light indicates that the trash can 100 is undergoing fresh air exchange; a green indicator light indicates that both sterilization and fresh air exchange are complete inside the trash can 100, and the user should clean the trash inside the trash can 100 in a timely manner.

[0068] like Figure 6 As shown, the trash can 100 is also equipped with a controller 6. The controller 6 is electrically connected to the weighing device 3, the disinfectant spraying module 4, the fan 5, and the switch 11, respectively. When the switch 11 is turned on, the controller 6 controls the weighing device 3 to start detecting the weight of the trash in the can and to determine whether the trash can 100 has met the sterilization conditions. If the sterilization conditions are met, the controller controls the disinfectant spraying module 4 to release disinfectant into the trash can 100. After the disinfectant is released, the controller controls the fan 5 to turn on so that the trash can 100 can start the fresh air exchange mode.

[0069] Furthermore, the controller 6 can be implemented using an industrial computer, embedded controller 6, or other electronic control system with certain network transmission capabilities and data storage and processing capabilities. The controller 6 may include a memory 61 and a processor 62, wherein the memory 61 stores a computer program, which, when executed by the processor 62, can perform any of the control methods in this embodiment to complete functions such as sterilization mode, fresh air exchange mode, data transmission, and internal control.

[0070] Those skilled in the art will understand that the present invention uses a weighing sensor 32 inside the trash can 100 to detect the weight of the trash inside and determines the amount of trash inside the trash can 100 to control the disinfectant spraying module 4 to spray disinfectant. Specifically, the weighing device 3 detects the weight of the trash inside the trash can 100, and then the controller 6 determines the weight of the trash inside the can, thereby controlling the disinfectant spraying module 4 to spray disinfectant to disinfect the trash inside the trash can 100. Therefore, the present invention overcomes the problem of bacterial growth caused by the long storage time of trash inside the trash can 100, and effectively disinfects the trash inside the trash can 100.

[0071] Further, while the sterilizing agent spraying module 4 sprays the sterilizing agent in the garbage can 100, the fan 5 is controlled to rotate at a set rotating speed and frequency conversion, so that the sterilizing agent can be quickly adsorbed on the surface of the garbage, and the sterilizing efficiency of the sterilizing agent spraying module 4 is improved.

[0072] Further, after the fan 5 of the lid 1 introduces air into the garbage can 100 for circulation, the gas is discharged outside the can through the air outlet 13, so that the garbage can 100 also has the function of replacing fresh air, so that the garbage can 100 will not produce a foul smell at the moment when it is opened by the user.

[0073] Further, by setting the fragrance at the air outlet 13 of the garbage can 100, the fragrance can be diffused into the air together with the air discharged from the garbage can 100, avoiding bringing a pungent odor to the surrounding personnel.

[0074] So far, the technical solutions of the present application have been described in combination with the foregoing embodiments, but those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Without deviating from the technical principles of the present application, those skilled in the art can split and combine the technical solutions in the above-mentioned embodiments, or make equivalent changes or replacements to the related technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.
