Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

Example 1

A first embodiment of the present invention relates to a dust collection method for a trash can, as shown in fig. 1, comprising the steps of:

step 110, detecting the concentration of particles in the air within a preset range from the garbage can in real time after receiving the opening and closing instruction of the can cover.

Step 120, determining whether the concentration of particulate matter is greater than a preset concentration.

And 130, if the concentration of the particulate matters is determined to be greater than the preset concentration, opening a vacuumizing device of the garbage can to enable at least one dust collection opening of the garbage can to form negative pressure, and generating air flow entering the can body of the garbage can from the at least one dust collection opening.

According to the method, after the opening instruction of the barrel cover is received, the concentration of the particles in the air in the preset range can be detected in real time, whether the concentration of the particles in the air is larger than the preset concentration is judged, and once the concentration of the particles in the air is judged to be larger than the preset concentration, the fact that dust emission phenomenon occurs due to the fact that the surrounding environment of the dustbin is quite likely to be put in garbage is indicated, so that the vacuumizing device of the dustbin is opened, at least one dust suction opening of the dustbin can form negative pressure under the action of the vacuumizing device, air flow entering the dustbin body from the dust suction opening can be generated, particles, hairs and other substances in the surrounding environment of the dustbin can be sucked into the dustbin body through the dust suction opening, and secondary pollution to the surrounding environment of the dustbin due to the dust emission phenomenon can be effectively avoided.

Specifically, in this embodiment, in order to detect the concentration of particulate matters in the surrounding environment of the trash can, as shown in fig. 2, a particulate matter detection module 6 may be disposed on the trash can, and the concentration of particulate matters in the air within a preset range from the trash can may be detected by the particulate matter detection module 6. Meanwhile, in order to form a negative pressure at the dust suction opening 31 of the dustbin after the vacuum apparatus 1 is opened, in this embodiment, as shown in fig. 3 and 4, the vacuum apparatus 1 is a blower, and of course, in practical application, the vacuum apparatus 1 may also use other apparatuses, such as: and a vacuum pump. In addition, a dust suction pipeline 5 connected with the vacuumizing device 1 can be arranged between the dust suction port 31 and the barrel port 21 of the barrel body 2 of the garbage can, wherein the dust suction pipeline 5 is provided with an inlet 51 communicated with the dust suction port 31 and an outlet 52 communicated with the barrel port 21 of the barrel body 2. Therefore, the negative pressure is formed at the dust collection opening 31 through the dust collection pipeline 5, and then the air flow entering the barrel body 2 is generated, so that the purpose of dust collection can be achieved.

In addition, as a preferred aspect, after determining that the concentration of the particulate matter is greater than the preset concentration, i.e. after step 120, and before opening the vacuuming device of the trash can, i.e. before step 130, as shown in fig. 1, the dust collection method of the present embodiment further includes the steps of:

step 121, judging whether the barrel cover closes the barrel opening of the garbage can.

If it is determined that the lid is closed, step 130 is performed, i.e. the vacuum extractor 1 of the trash can is opened.

Therefore, it is not difficult to find that the opening of the vacuumizing device 1 is performed after the barrel cover closes the barrel opening 21 of the barrel body 2, so that the garbage sucked into the dust suction pipeline 5 can be directly blocked by the barrel cover when discharged through the outlet 52 of the dust suction pipeline 5, and the garbage can directly fall into the garbage bag laid in the barrel body 2, and therefore, the secondary dust-raising phenomenon caused by the fact that the barrel opening 2 is in an open state in the process of feeding the particles such as dust and hair sucked into the dust suction pipeline 5 into the barrel body 2 through the barrel opening 21 can be effectively avoided, and the cleanliness of the surrounding environment of the garbage can be further improved.

In addition, it should be noted that, in this embodiment, after the vacuum device of the garbage can is opened to form a negative pressure at least one dust suction port of the garbage can, and an airflow is generated from the at least one dust suction port into the can body of the garbage can, that is, after step 130, as shown in fig. 1, the method further includes the following steps:

and 140, continuing to detect the concentration of the particles in the air within a preset range from the garbage can.

Step 150, judging whether the concentration of the particulate matter is less than a preset concentration.

And step 160, if the concentration of the particulate matters is less than the preset concentration, closing the vacuumizing device of the garbage can.

Because after opening the evacuating device 1, the concentration of the particulate matters in the air within the preset range of the dustbin can be continuously detected, once the detected concentration of the particulate matters in the air is smaller than the preset concentration, the dust emission phenomenon in the environment around the dustbin is basically solved, and the evacuating device can be closed at the moment, so that the energy consumption of the dustbin can be effectively reduced, and the dustbin has longer service life.

Further, preferably, after determining whether the concentration of the particulate matter is less than the preset concentration, i.e., after step 150, as shown in fig. 1, the following sub-steps are further included:

step 170, if the particulate matter concentration is not less than the preset concentration, calculating the vacuumizing duration of the vacuumizing device, and judging whether the vacuumizing duration of the vacuumizing device is greater than the preset duration.

And 180, if the vacuumizing time of the vacuumizing device is longer than the preset time, continuing to judge whether the dust collection pipeline is blocked. If it is determined that the vacuumizing duration of the vacuumizing device is not longer than the preset duration, the process returns to step 170.

Step 190, if it is determined that the suction line is blocked, the vacuum device is continuously driven at a maximum power greater than the current standard power for a preset period of time. If it is determined that the suction line is not blocked, the process returns to step 140.

As can be seen from the above, since it is still necessary to continuously determine whether the vacuumizing duration of the vacuumizing device 1 is longer than the preset duration after determining that the concentration of the particulate matter is not less than the preset concentration, when it is determined that the vacuumizing duration is longer than the preset duration, it is stated that the dust collection is likely to be performed due to the fact that the dust collection of the dust particles around the garbage can is not completed, or the dust collection pipeline is likely to be blocked, so that the dust collection port cannot generate the expected negative pressure, and the continuous phenomenon of dust collection is caused. Therefore, when the time period of vacuum pumping is longer than the preset time period, whether the dust collection pipeline 5 is blocked needs to be further judged, once the dust collection pipeline 5 is judged to be blocked, the power of the vacuum pumping device 1 can be increased within the preset time period, so that the vacuum pumping device 1 can work with the maximum power, the negative pressure in the dust collection pipeline 5 is further increased, and therefore the blocking object blocking the dust collection pipeline 5 can be discharged into a garbage bag paved on the barrel body 2 from the outlet 52 of the dust collection pipeline 5 as much as possible.

In order to accurately determine whether the dust collection line 5 is clogged, in the step of determining whether the dust collection line 5 is clogged, that is, step 180 specifically includes:

the flow rate of the air flow when it passes through the outlet of the suction line 5 is detected when the vacuum is opened.

If the detected flow velocity of the air flow is smaller than the preset flow velocity, judging that the dust collection pipeline is blocked.

If the detected flow velocity of the air flow is greater than or equal to the preset flow velocity, judging that the dust collection pipeline is not blocked.

Specifically, a flow sensor may be disposed at the outlet 52 of the dust collection pipe 5, and the flow rate of the airflow may be detected by the flow sensor when the airflow passes through the outlet 52 of the dust collection pipe 5. Therefore, when the detected flow rate of the airflow is greater than or equal to the preset flow rate, it indicates that no blockage phenomenon occurs in the dust collection pipeline 5 at this time, and a sufficient negative pressure is provided. And once the flow rate of the air flow is detected to be smaller than the preset flow rate, the negative pressure in the dust collection pipeline 5 is too small, so that the dust collection port 31 loses the dust collection capability.

Further, preferably, after continuing to drive the vacuum pumping apparatus at the maximum power greater than the current standard power for the preset period of time, that is, after step 190, as shown in fig. 1, the method further includes the steps of:

step 200, judging whether the dust collection pipeline is still blocked.

Step 210, if it is determined that the dust collection pipeline is still blocked, the vacuum pumping device is turned off, and an alarm prompt is sent. If it is determined that the suction line is not blocked, the process returns to step 140.

If the vacuum apparatus 1 is continuously driven at the maximum power within the preset period, the vacuum pipe 5 is still blocked, which means that the blocking phenomenon of the vacuum pipe 5 cannot be eliminated by increasing the power of the vacuum apparatus 1. At this time, the vacuum-pumping device can be directly turned off, so that the vacuum-pumping device 1 is protected, and the influence on the service life of the vacuum-pumping device 1 due to the fact that the vacuum-pumping device 1 operates at the maximum power for a long time is avoided. Meanwhile, an alarm prompt can be sent out to remind a user of eliminating the blockage phenomenon of the dust collection pipeline 5 in a manual mode. In addition, in this embodiment, in order to enable the trash can to send out an alarm prompt, an acoustic alarm module may be disposed on the trash can, for example: a buzzer; alternatively, an optical alarm module is provided, such as: the alarm lamp, or alternatively, the audible alarm module and the visual alarm module can be set at the same time to achieve the aim of audible and visual alarm. However, in practical application, other methods for sending out the alarm prompt may be adopted, for example: the user is alerted in the form of an error code, but in this embodiment, the manner in which the alert is issued is not specifically limited.

In order to accurately determine whether the dust collection pipe 5 is still blocked, in the step of determining whether the dust collection pipe 5 is still blocked, that is, step 200 specifically includes:

the average flow rate of the airflow as it passes through the outlet of the suction line is calculated.

If the calculated average flow rate of the air flow is smaller than the preset average flow rate, judging that the dust collection pipeline is still blocked.

If the calculated average flow velocity of the air flow is greater than or equal to the preset average flow velocity, judging that the dust collection pipeline is not blocked.

Specifically, the flow sensor disposed at the outlet 52 of the dust collection pipeline 5 can continuously detect the airflow velocity at the outlet 52 of the dust collection pipeline 52 within a preset period, so that the flow sensor can detect the flow velocity of a plurality of airflows within the preset period, and the main control module of the garbage can calculate the average flow velocity of the airflows within the preset period according to the airflow velocities detected by the flow sensor, once the calculated average flow velocity is still smaller than the preset average flow velocity, the dust collection pipeline 52 is still in a blocking state, and when the calculated average flow velocity is larger than or equal to the preset average flow velocity, the blocking object in the dust collection pipeline 52 is discharged into the garbage bag paved in the garbage can 2.

Example two

A second embodiment of the present invention relates to a dust collection method of a dust bin, which is a further improvement on the basis of the first embodiment, and is mainly improved in that, as shown in fig. 6, in the present embodiment, a plurality of dust collection openings 31 may be provided, and each dust collection opening is circumferentially arranged around the dust bin, so as to further improve the dust collection effect of the dust bin, and reduce the energy consumption of the dust bin during dust collection, and after the particulate matter concentration is determined to be greater than the preset concentration, i.e., after step 120, as shown in fig. 5, the dust collection method of the present embodiment further includes the following sub-steps:

step 220, determining dust collection direction in which the concentration of the particulate matters is larger than the preset concentration within a preset range from the garbage can. Wherein, each dust collection opening 31 corresponds to one dust collection direction.

Step 230, opening the dust collection openings corresponding to the dust collection directions with the particle concentration larger than the preset concentration, and closing the dust collection openings corresponding to the dust collection directions with the particle concentration not larger than the preset concentration.

It is apparent from the above that, since the dust generated by throwing the garbage generally does not have directivity, that is, the dust may spread in the same direction or may spread around the garbage can, in order to improve the dust collection effect of the garbage can, it is necessary to determine the spreading direction of the dust after determining that the concentration of the particulate matters is greater than the preset concentration, that is, determine the dust collection direction in which the concentration of the particulate matters is greater than the preset concentration. Then, according to the determined dust collection direction, the dust collection opening 31 corresponding to each dust collection direction with the particle concentration larger than the preset concentration is opened, and meanwhile, the dust collection opening 31 corresponding to each dust collection direction with the particle concentration not larger than the preset concentration is closed, so that the dust collection range of the garbage can is enlarged while the dust collection capacity of each dust collection opening 31 is not affected, and meanwhile, the negative pressure of each opened dust collection opening 31 can be effectively improved, and the dust collection work of the garbage can be completed rapidly.

Specifically, in order to accurately determine the dust collection direction in which the concentration of the particulate matters is greater than the preset concentration, in this embodiment, as shown in fig. 5, the dust collection openings 31 are adjacent to the garbage can, and the particulate matter detection modules 6 are further disposed respectively, and each of the particulate matter detection modules 6 is used for detecting the concentration of the particulate matters in the air. Therefore, in the step of determining the dust collection direction in which the concentration of the particulate matter is greater than the preset concentration within the preset range from the trash can, that is, step 210 specifically includes:

and acquiring the concentration of the particles detected by each particle detection module.

In addition, it should be noted that, in order to open the dust collection openings 31 corresponding to the dust collection directions in which the concentration of the particulate matter is greater than the preset concentration, the dust collection openings 31 corresponding to the dust collection directions in which the concentration of the particulate matter is not greater than the preset concentration are closed. In this embodiment, electromagnetic valves may be respectively disposed in each dust collection port 31, and each electromagnetic valve is in communication connection with a main control module of the dustbin, and the control of each electromagnetic valve by the main control module can control the opening and closing of each dust collection port 31.

Example III

A third embodiment of the present invention relates to a trash can, as shown in fig. 7, 8 and 9, comprising: barrel body 2, base 3, evacuating device 1, particulate matter detection module 6.

As shown in fig. 7 and 8, the tub 2 has, along a predetermined axis direction: a bung 21 and a bung bottom 22. The base 3 is provided at the bottom 22 of the tub 2, and the base 3 has at least one suction port 31, and each suction port 31 communicates with the tub 21.

Next, in the present embodiment, as shown in fig. 7, the vacuum apparatus 1 acts on each of the suction ports 31, and when opened, the vacuum apparatus is configured to cause at least one of the suction ports 31 to form a negative pressure, thereby generating an air flow from the at least one suction port 31 into the body 2 of the trash can. In addition, the particulate matter detection module 6 is configured to detect the concentration of particulate matter in the air within a predetermined range from the tub 2.

And, referring to fig. 10, the main control module is respectively connected with the particulate matter detection module 6 and the vacuumizing device 1 in a communication manner. In practical application, the main control module is used for opening the particle detection module 6 after receiving the opening and closing instruction of the barrel cover, so that the particle detection module 6 detects the concentration of particles in the air within a preset range from the dustbin in real time. The main control module is further used for judging whether the concentration of the particles detected by the particle detection module 6 is greater than a preset concentration or not, and for opening the vacuumizing device 1 when judging that the concentration is greater than the preset concentration, so that substances such as particles and hairs in the surrounding environment of the garbage can be sucked into the barrel body 2 through the dust suction opening 31, and secondary pollution to the surrounding environment of the garbage can caused by dust raising is effectively avoided.

Specifically, in the present embodiment, as shown in fig. 9, a plurality of dust collection ports 31 are provided and circumferentially disposed around the chassis 3, and in order to allow each of the dust collection ports 31 to communicate with the bung 21 of the bung 2, the trash can of the present embodiment further includes: a suction line 5, and the suction line 5 has an outlet 52 communicating with the tub mouth 21, and an inlet 51 communicating with the suction port 31. In the present embodiment, as shown in fig. 9, a plurality of particulate matter detection modules 6 may be provided, and the number of particulate matter detection modules 6 is the same as the number of dust collection ports 31 and is provided so as to correspond to one another. In addition, each particulate matter detection module 6 is disposed adjacent to the only corresponding dust collection opening 31, and each particulate matter detection module 6 is used for detecting the concentration of particulate matters in the air.

In addition, as a preferable scheme, since the dust generated by throwing garbage generally does not have directivity, that is, the dust may spread in the same direction, and may spread around the garbage can, the main control module is further configured to determine the dust direction, that is, determine the dust collection direction of the garbage can, after detecting that the concentration of the particulate matters in the air is greater than the preset concentration by the particulate matter detection module 6, as shown in fig. 10. Meanwhile, since the dust collection openings 31 are arranged around the axis of the base 3, so that different dust collection openings 31 can have different dust collection directions, in order to improve the dust collection efficiency of the garbage can, the garbage can of the embodiment further comprises: a plurality of electromagnetic valves (not labeled in the figure), the number of the electromagnetic valves is the same as that of the dust collection openings 31, and the electromagnetic valves are arranged in the dust collection openings 31 which are uniquely corresponding to each other, and are used for opening or closing the dust collection openings 31 which are uniquely corresponding to each other. And, as shown in connection with fig. 10, each solenoid valve is also in communication connection with the main control module.

In practical application, as shown in fig. 10, when the main control module determines that the concentration of the particulate matters detected by any one particulate matter detection module 6 is greater than the preset concentration, the dust collection direction of the garbage can be directly determined, the electromagnetic valve uniquely corresponding to the dust collection direction is controlled, so that the electromagnetic valve can be opened to uniquely corresponding dust collection port 31, meanwhile, the main control module can also control the electromagnetic valve corresponding to the dust collection port 31 in the dust collection direction with the concentration of the particulate matters smaller than the preset concentration, so that the electromagnetic valves can be directly closed to uniquely corresponding dust collection port 31, therefore, the dust collection range of the garbage can be enlarged while the dust collection capacity of each dust collection port 31 is not influenced, and meanwhile, the negative pressure of the opened dust collection port 31 can be effectively improved, so that the dust collection work can be rapidly completed.

As can be seen from the foregoing, this embodiment is an example of a trash can corresponding to the first and second embodiments, and can be implemented in cooperation with the first and second embodiments. The related technical details mentioned in the first and second embodiments are still valid in this embodiment, and in order to reduce repetition, a detailed description thereof is omitted.
