At present, the amount of garbage bags stored in a garbage can is generally checked by a user, and the stored boxes need to be opened to check the remaining length or number, so that the garbage can is very inconvenient; in some related arts, the components for housing are provided to be transparent for easy observation, but still require user inspection. Some intelligent garbage bins can pack used disposal bags and automatically replace the disposal bags, and the phenomenon of scattering can occur under the condition that no disposal bag exists, so that inconvenience can not be brought to users due to the fact that the disposal bags cannot be supplemented in time.

As shown in fig. 1 to 4, the trash can 10 may include: a containment box 11, a magnet 12 and a measurement and control assembly 13.

Wherein the receptacle 11 may have a cavity 111 for receiving the garbage bag 20, wherein the garbage bag 20 has a magnetic blocking component. The trash bag 20 of the present disclosure may be received in the cavity 111 in a stacked manner or in a rolled manner. The trash bags 20 may be formed into a bag shape, and the bag shape is a ribbon-like set with a certain length formed by connecting the ends of the bag shape, and when the bag shape needs to be taken out, one of the trash bags 20 which is stacked or wound at the outermost end is taken down. The garbage bag 20 stored in the cavity 111 can also be a tube body without closing up, when the previous bag is packed, the bag opening is closed up in a sealing mode through hot melting and the like, the sealing part is the bag opening of the used previous bag on the one hand and the bag bottom of the next bag on the other hand, the bag bottom is formed through sealing, and the continuous tube body is taken out to form a new bag body for containing garbage.

The receiving box 11 may be disposed at an upper portion of the garbage can 10 above the can body 14, and the garbage bag 20 drawn out of the cavity 111 of the receiving box 11 may be conveniently placed in the can body 14 to receive garbage in normal use.

In one embodiment, as shown in fig. 2, the accommodating box 11 may be disposed at one side of the barrel 14 for accommodating the garbage bag 20, an opening 112 is disposed below or at one side of the accommodating box 11, and the garbage bag 20 accommodated in the cavity 111 may extend from the opening 112, be extracted when needed, and be sleeved on the barrel 14. In this embodiment, the trash bag 20 may be a formed bag body, which is formed into a belt shape by being connected end to end, and is accommodated in the cavity 111 inside the accommodating box 11 in a winding or stacking manner.

In another embodiment, as shown in FIG. 1, the accommodating case 11 may have a ring shape, and is circumferentially disposed above the tub 14, and the center of the ring shape of the accommodating case 11 corresponds to the opening of the tub 14. In this embodiment, the cavity 111 for accommodating the box 11 may also be in a ring shape, the garbage bag 20 may be a tubular belt material, which is accommodated in the cavity 111 in a stacking or winding manner, and may extend out through the opening 112 disposed below or on the side of the accommodating box 11, the extended tubular belt material may be closed up by heat melting or other manners, a bottom for accommodating garbage is formed after closing up, the tubular belt material is used as a bag body, when the garbage bag is filled or needs to be discarded, the bag body may be sealed by heat melting, the closed-up portion is separated, a sealed bag body for accommodating garbage is formed below, and the top closed-up portion is used as the bottom of a new bag. Therefore, the garbage bag 20 can be conveniently and automatically taken and placed, and a user does not need to seal the garbage bag by himself or manually place a new garbage bag.

As shown in fig. 3 and 4, the magnet 12 is disposed at one side of the cavity 111 for providing a magnetic field. The magnet 12 may be a permanent magnet or an electromagnet for providing a stable, constant magnetic field strength. Since the remaining amount of the dust bag 20 needs to be determined according to the strength of the magnetic field, providing a stable magnetic field can improve the accuracy of the determination. In some embodiments, calibration may also be performed without placing a garbage bag 20 in the cavity 111, so as to ensure the accuracy of the determination, which is specifically described in the following embodiments. In the case that the garbage bag 20 is placed in the cavity 111, the magnetic field provided by the magnet 12 and capable of passing through the cavity 111 has a certain reduction in the magnetic field strength due to the magnetic blocking component of the garbage bag 20. The more the garbage bags 20 are, the more the magnetic field intensity is reduced, on the contrary, when the garbage bags 20 are reduced, the blocking effect on the magnetic field is gradually reduced, and the magnetic field intensity passing through the cavity 111 is also increased. The measurement and control assembly 13 may be configured to sense the magnetic field strength across the cavity 111 and determine the remaining volume of the trash bag 20 based on the magnetic field strength in accordance with the principles described above. Through the mode of the embodiment of the disclosure, the allowance of the garbage bag can be determined in real time, so that a user can be reminded in time when the garbage bag is insufficient, and the garbage bag can be supplemented in time under the condition that the allowance of the garbage bag is zero.

In some embodiments, as shown in fig. 3 and 4, the measurement and control assembly 13 may include: the magnetic field sensor 131 is disposed on the opposite side of the cavity 111 from the magnet 12, so that the garbage bag 20 is located between the magnet 12 and the magnetic field sensor 131 when being accommodated in the cavity 111, and the magnetic field sensor 131 is configured to sense a magnetic field strength of the magnetic field and output an electrical signal corresponding to the magnetic field strength. The magnetic field sensor 131 may be a hall sensor, or other sensor that will receive magnetic field strength and output an electrical signal in response. Taking the hall sensor as an example, a linear hall sensor can be adopted, and after sensing the magnetic field, the magnetic field intensity of the magnetic field can be converted into a voltage signal. Fig. 5A and 5B schematically show the output voltage of different linear hall sensors in relation to the magnetic field strength, wherein the horizontal axis represents the magnetic field strength and the vertical axis represents the input voltage, as shown in fig. 5A, the output voltage of the linear hall sensor increases with increasing magnetic field strength, and as shown in fig. 5B, the output voltage of the linear hall sensor decreases with increasing magnetic field strength. The output voltage of the two linear Hall sensors can reflect the change of the magnetic field intensity. As mentioned above, the magnet 12 provides a stable magnetic field, and the magnetic field intensity is reduced by the obstruction of the garbage bag 20 with the magnetic resisting material, and the margin is gradually reduced along with the use of the garbage bag 20, the obstruction to the magnetic field is less and less, the magnetic field intensity sensed by the magnetic field sensor 131 is larger, and the corresponding output voltage is larger or smaller, so that the magnitude of the magnetic field intensity can be determined according to the magnitude of the output voltage, and then the margin of the garbage bag 20 is determined.

In an embodiment, as shown in fig. 3, the measurement and control assembly 13 may further include: an analog-to-digital converter 132 for receiving the electrical signal output by the magnetic field sensor 131, converting the electrical signal into a digital signal and outputting the digital signal; a controller 133 for receiving the digital signal and determining the remaining amount of the trash bag 20 based on the digital signal. In this embodiment, the controller 133 may be a Micro Controller Unit (MCU) and is responsible for overall control, the Analog-to-Digital Converter (ADC) 132 may be configured to receive an Analog voltage signal output from the magnetic field sensor 131 (e.g., a linear hall sensor) and convert an Analog quantity into a Digital voltage recognizable by the controller 133, the magnetic field strength detected by the magnetic field sensor 131 is finally reflected in the output voltage value and input to the controller 133, the controller 133 determines the remaining quantity of the trash bag 20, the acquired voltage value may be compared with a preset voltage threshold, if the voltage value is greater than or equal to the voltage threshold, the magnetic field strength is relatively strong, which indicates that the remaining quantity of the trash bag is insufficient, and corresponding processing may be performed according to the current remaining quantity, such as timely reminding a user to replenish the trash bag, if the voltage value is less than the voltage threshold, the magnetic field strength is relatively weak, which indicates that the garbage bag has sufficient margin and does not need to be replaced.

In the embodiment of the present disclosure, the garbage bag 20 contains a magnetic resistance material, which may be made of plastic containing metal components, for example, plastic bags containing ferrite components are mixed during the manufacturing process; alternatively, the garbage bag 20 with the magnetic resistance effect may be formed by attaching a film containing a barrier material to the surface of the bag body.

Fig. 6A and 6B schematically show the garbage bag 20 being accommodated in the cavity 111 by winding, and the garbage bag 20 being accommodated in the cavity, protruding from the opening 112, and being located between the magnet 12 and the magnetic field sensor 131. As shown in fig. 6A, since the garbage bags 20 are initially stored in a large number and long in length, and the diameter of the formed garbage bag roll is larger, the blocking of the magnetic field is also larger, and the garbage bag roll is gradually reduced and thinned in the using process, as shown in fig. 6B, the magnetic shielding performance of the garbage bag roll is also reduced, the magnetic field intensity of the magnetic field generated by the magnet 12 and detected by the magnetic field sensor 131 after passing through the cavity 111 is stronger and stronger, and then the change of the voltage is reflected, and the controller 133 can determine the current remaining amount of the garbage bag 20 and perform corresponding processing.

Fig. 7A and 7B schematically show the garbage bags 20 being accommodated in the cavity 111 in a stacked manner, the garbage bags 20 being accommodated in the cavity, protruding from the opening 112, and being located between the magnet 12 and the magnetic field sensor 131. Unlike the former winding type of storage, the stacked and stored dust bags 20 become thinner only in the thickness direction of the stack (vertical direction in fig. 7A and 7B) and hardly change in the width direction (horizontal direction in fig. 7A and 7B) as they are used, and therefore, in the present embodiment, the magnet 12 and the magnetic field sensor 131 need to be provided on opposite sides of the stack of dust bags 20 in the thickness direction so as to be able to reflect the change in the magnetic field strength when the remaining amount of the dust bags 20 changes. In some embodiments, when the stacked trash bags 20 are placed, the magnet 12 and the magnetic field sensor 131 of the trash can 10 may be placed correspondingly. In other embodiments, the positions of the magnet 12 and the magnetic field sensor 131 may be adjusted, and the positions of the magnet 12 and the magnetic field sensor 131 may be adjusted according to the thickness direction of the stacked trash bags 20, so that the magnet 12 and the magnetic field sensor 131 are disposed on two opposite sides of the stacked trash bags 20 in the thickness direction. As shown in fig. 7A, since the garbage bags 20 are initially stored in a large number and long in length, and the formed garbage bag stacking height is larger, the blocking of the magnetic field is also larger, the garbage bags are gradually reduced and the thickness of the garbage bags is reduced in the using process, as shown in fig. 7B, the magnetic blocking performance of the garbage bags is also reduced, the magnetic field intensity of the magnetic field generated by the magnet 12 and detected by the magnetic field sensor 131 after passing through the cavity 111 is stronger and stronger, and then the change of the voltage is reflected, and the controller 133 can determine the current remaining amount of the garbage bag 20 and perform corresponding processing.

In one embodiment, the trash can 10 may further include: and a prompting device (not shown) for sending a prompting message for prompting the shortage of the remaining amount of the garbage bag 20 when the controller 133 determines that the remaining amount of the garbage bag 20 is insufficient. When the remaining amount of the dust bag 20 is insufficient, the controller 133 causes the presentation device to present the remaining amount. For example, when the controller 133 determines that the remaining number of trash bags 20 is less than 5 bags or other value, a reminder may be issued to the user via the prompting device. The prompting device may be of various types, for example, it may be a speaker mounted on the trash can 10 for providing an audible prompt; or a lamp arranged on the garbage can 10 for prompting by lighting; or a display screen installed on the trash can 10, and prompts are given by displaying corresponding contents; the device can also be a device capable of sending signals, prompt information is sent to other terminals such as mobile phones and wearable equipment of users in a WiFi mode, a Bluetooth mode and the like, and the users can receive the prompt information at the first time.

In one embodiment, the trash can 10 may further include: a garbage bag packing device (not shown) for packing the used garbage bag 20; wherein, when the remaining amount of the garbage bags 20 is zero, the controller 133 prohibits the garbage bag packing device from packing the used garbage bags. In this embodiment, the trash can 10 can seal the used trash bag through the trash bag packaging device, and the seal can also be used as the back cover of the next trash bag. In the case that the controller 133 determines that there are no garbage bags left in the cavity 111, the garbage bag packing device may be prohibited from packing the currently used garbage bag, so as to avoid that the garbage can 10 is not available for use after packing.

In one embodiment, the trash can 10 may further include: a waste bag replenishing device (not shown) comprising: a storage chamber storing a plurality of trash bags; the disposal bag replenishing means is for replenishing the disposal bag to the housing box 11 when the controller 133 detects that the remaining amount of the disposal bag 20 in the housing box 11 is zero. In this embodiment, the trash can 10 may be provided with a trash bag replenishing device, wherein the trash bag replenishing device may store a plurality of trash bags 20 stored in a winding or stacking manner in a storage cavity, and the storage cavity may be located directly above or obliquely above the cavity containing the box 11, and an openable opening may be provided directly below or laterally below the storage cavity, and when the trash bag 20 in the cavity containing the box 11 is zero, the opening of the storage cavity may be opened, so that the lowermost trash bag may enter the cavity containing the box 11 in a manner of falling or sliding in, and the replenishment of the trash bags is completed. In other embodiments, the disposal bag refilling apparatus may also store a plurality of cavities for accommodating the disposal bags 20, and the disposal bag refilling apparatus is adapted to a trash can with replaceable cavities, i.e. the cavities in the accommodating box 11 are independent of the accommodating box 11, and can be detached and replaced. After no disposal bag in the current cavity, can be through changing the cavity that has the disposal bag, the cavity that gets off changed can mend the disposal bag in disposal bag filling device again to change next time. Under the condition that the controller 133 judges that the residual quantity of the garbage bags in the current cavity 111 is zero, a new roll or a stack of garbage bags can be automatically replenished from the garbage bag replenishing device and enter the accommodating box, so that the garbage can be automatically replenished after the previous roll or stack of garbage bags are used up, and the situation that no garbage bag exists in the garbage can is avoided.

Based on the same concept, the embodiment of the present disclosure further provides a garbage bag remaining amount detection method 30, which is applied to the garbage can 10 of any of the foregoing embodiments. As shown in fig. 8, the garbage bag remaining amount detecting method 30 may include: step S31, obtaining the magnetic field intensity, wherein the magnetic field intensity is the magnetic field intensity of the magnetic field passing through the cavity; in step S32, the remaining amount of the dust bag is determined based on the magnetic field intensity. Through magnetic field intensity, confirm the surplus of disposal bag, can confirm the surplus of disposal bag in real time, convenient remind or carry out other controls to the garbage bin, made things convenient for the user, improve user experience, avoid rubbish to lose and spill.

In one embodiment, step S32 may include: acquiring an electric signal corresponding to the magnetic field intensity through a magnetic field sensor; acquiring a voltage value of the electric signal; if the voltage value is smaller than the first threshold value, determining that the margin of the garbage bag is sufficient; and if the voltage value is larger than or equal to the first threshold value, determining that the garbage bag is insufficient in allowance. In the trash can 10, the trash bag 20 has an effect of blocking a magnetic field, when the remaining amount of the trash bag 20 is sufficient, the magnetic field strength sensed at the other end of the cavity 111 is low, as described above, the magnetic field strength is detected by the magnetic field sensor such as the hall sensor, and the magnetic field strength is further converted into a voltage value of a voltage signal by the elements such as the analog-to-digital converter, so that the controller judges according to the voltage value that the voltage value is relatively low when the magnetic field strength is low, and therefore, when the voltage value is smaller than the first threshold value, it can be determined that the remaining amount of the trash bag is sufficient; correspondingly, when the remaining amount of the garbage bag 20 is insufficient, the blocking effect on the magnetic field is also reduced, the sensed magnetic field intensity at the other end of the cavity 111 is increased, the voltage value is also increased, and therefore, the voltage value is greater than or equal to the first threshold value, and it can be determined that the remaining amount of the garbage bag is insufficient.

In an embodiment, step S32 may further include: if the voltage value is larger than or equal to the second threshold value, determining that the garbage bag allowance is zero; wherein the second threshold is greater than the first threshold. On the basis of the previous embodiment, a second threshold higher than the first threshold may be determined, and when the voltage value is greater than or equal to the second threshold, that is, the magnetic field strength is stronger, it may be determined that the remaining quantity of the garbage bag is zero. Through the second threshold value, whether the garbage bag surplus is zero can be judged automatically in real time, corresponding prompt can be carried out under the condition that the garbage bag surplus is zero, operations such as automatic garbage bag supplement can also be carried out, the situation that the garbage bag is left to scatter and the like caused by the fact that no garbage bag is arranged in the garbage can is avoided, convenience is brought to a user, and therefore user experience is improved.

In an embodiment, the method 30 for detecting the remaining amount of the garbage bag further includes: under the condition that a garbage bag is not placed in the cavity, acquiring the vacant magnetic field intensity of the magnetic field; determining a null voltage value based on the null magnetic field strength; based on the idle voltage value, a second threshold is determined. In this embodiment, under the condition that no disposal bag is placed in the cavity, the intensity of the magnetic field, that is, the vacant magnetic field intensity is obtained, the magnetic field intensity during the vacant state is converted into a vacant voltage value through the hall sensor, and the vacant voltage value can be directly used as the second threshold value. The second threshold may be conveniently set in this embodiment, and on this basis, the first threshold may be further set, for example, the idle voltage value is used as the second threshold, and then the intensity value of 90% of the idle voltage value is used as the first threshold. Through the embodiment, the magnetic field can be calibrated, and the problem of inaccurate judgment caused by unstable magnetic field of the magnet 12 is avoided. The user may perform the calibration operation when there is no garbage bag 20 in the cavity 111, or perform the calibration each time when it is detected that the remaining amount of the garbage bag 20 in the cavity 111 is zero, and use the sensed idle voltage value when the remaining amount is zero as a new second threshold.
