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 an air path system of a trash can, as shown in fig. 1 and 2, comprising: a dust suction pipeline 1, an exhaust pipeline 2, a laying pipeline 3, a first vacuumizing device 4 and a second vacuumizing device 5.
As shown in fig. 1, 2 and 3, first, the dust collection line 1 includes: an air inlet end 11 communicated with the dust suction nozzle 6 of the garbage can and an air outlet end 12 connected with an air outlet channel 71 of the dust-air separation box 7 of the garbage can. Next, as shown in fig. 3 and 4, the exhaust pipe 2 includes: a return air end 21 connected to the return air passage 72 of the dust-air separation box 7, and an exhaust end 22 communicating with the outside atmosphere. Finally, the laying pipeline 3 has: an air inlet side 31 coaxially arranged with the body 8 of the trash can.
In the present embodiment, as shown in fig. 1 and 2, the first evacuating device 4 is configured to act on the laying pipeline 3 when opened, so that the laying pipeline 3 can generate an air flow into the tub 8 through the tub opening 81 of the tub 8. Meanwhile, as shown in fig. 1 and 2, the second vacuumizing device 5 is used for acting on the dust collection pipeline 1 and the exhaust pipeline 2 when being opened, so that the dust collection nozzle 6 forms negative pressure, and generates air flow entering the air outlet channel 71 through the dust collection pipeline 1, and meanwhile, redundant air flow in the barrel body 8 of the garbage can enters the exhaust pipeline 2 through the air return channel 72.
In addition, as shown in fig. 5, the main control module is respectively connected with the first vacuumizing device 4 and the second vacuumizing device 5 in a communication manner, and is used for receiving a garbage bag paving instruction and opening the first vacuumizing device 4 and the second vacuumizing device 5 after receiving the garbage bag paving instruction.
As can be seen from the above, after the main control module of the garbage can receives the garbage bag paving instruction, the main control module can respectively open the first vacuumizing device 4 and the second vacuumizing device 5, and act on the paving pipeline 3 through the first vacuumizing device 4, so that the paving pipeline 3 can generate air flow entering the can body 8 through the can opening 81; at the same time, the second vacuum device 5 acts on the suction line 1 and the exhaust line 2, so that the suction nozzle 6 forms a negative pressure and an air flow into the air outlet channel 71 is generated through the suction line 1. It can be seen from this that, because the garbage can is laid and sucked by the first vacuum pumping device 4 and the second vacuum pumping device 5 for the garbage bag, the negative pressure is respectively provided for the laying pipe 3 and the dust suction pipeline 1, so that the garbage can has better garbage bag laying performance and better dust suction performance. In addition, when the laying pipeline 3 lays the garbage bag, the second vacuumizing device 5 can generate air flow entering the air outlet channel 71, so that the air outlet channel 71 can exhaust dust particles into the barrel body 8 while exhausting the dust particles into the barrel body 8, and therefore, the laying speed of the garbage bag in the barrel body can be further accelerated by virtue of the air flow exhausted into the barrel body by the air outlet channel 71, and the garbage bag can be laid in the barrel body 8 in a short time.
Specifically, in the present embodiment, as shown in fig. 1, the dust collection pipe 1 includes: a first bottom pipe 13 placed in the base 9 of the dustbin, a first side pipe 14 placed on the side of the dustbin body 6. As shown in fig. 1, the first bottom line 13 has: an air inlet end 11 connected with the dust suction nozzle 6, a first air outlet 15 arranged far away from the air inlet end, and the first air outlet 15 is connected with an air inlet side (not labeled in the figure) of the first vacuumizing device 4. In addition, as shown in fig. 1, the first side pipe 14 has: a first air inlet 16 connected to an air outlet side (not shown) of the first vacuum pumping device 4, an air outlet end 12 connected to the air outlet channel 71, and the air outlet end 12 is disposed away from the first air inlet 16 along an axial direction of the tub 8.
Next, in the present embodiment, as shown in fig. 2, the exhaust pipe 2 includes: a second bottom pipeline 23 arranged at the barrel bottom 82 of the barrel body 8 and a second side pipeline 24 arranged at the side surface of the barrel body 8. As shown in fig. 2, 3 and 4, the second bottom line 23 has: an exhaust end 22 communicating with the outside atmosphere, a second air intake 25 disposed away from the exhaust end 22. Meanwhile, the second side pipe 24 has: the air return end 21 connected to the air return passage 72, the second air outlet 26 connected to the second air inlet 25, and the second air outlet 26 is provided away from the air return end 21 in the axial direction of the tub 8.
Finally, in the present embodiment, as shown in fig. 1, the laying pipeline 3 is provided at the bottom 82 of the bucket body 8 along the axial direction of the bucket body 8. The second vacuumizing device 5 is disposed in the laying pipeline 3, and the direction from the air inlet side (not labeled in the figure) to the air outlet side (not labeled in the figure) of the second vacuumizing device 5 is the axial direction of the barrel 8.
In the present embodiment, as shown in fig. 1, the first vacuum extractor 4 and the second vacuum extractor 5 may each use a blower, but in practical application, the first vacuum extractor 4 and the second vacuum extractor 5 may use other vacuum extractor elements, and in the present embodiment, the types of the first vacuum extractor 4 and the second vacuum extractor 5 are not specifically limited.
In addition, in the present embodiment, as shown in fig. 5, the main control module is configured to sequentially open the first vacuumizing device 4 and the second vacuumizing device 5 after receiving a garbage bag laying instruction. For example, the second vacuumizing device 5 is opened at a predetermined time interval from the first vacuumizing device 4, and the predetermined time interval is shorter than the time interval for paving the garbage bag on the bottom 82 of the barrel body 8. Therefore, the first vacuumizing device 4 and the second vacuumizing device 5 work sequentially, so that after the garbage bags are paved in the barrel body 8 for a certain length, the main control module can open the second vacuumizing device 5, and dust particles discharged from the air outlet channel 71 into the barrel body 8 can be accurately sent into the garbage bags without polluting the inside of the barrel body 8 while the paving efficiency of the garbage bags is not affected.
Example two
A second embodiment of the present invention relates to an air duct system of a trash can, which is substantially the same as the first embodiment, and is mainly different in that in the first embodiment, the opening of the second vacuum pumping apparatus 5 is controlled by timing the opening time of the first vacuum pumping apparatus 4 by the main control module.
In this embodiment, in order to enable the main control module to effectively control the opening of the first vacuum pumping device 4 and the second vacuum pumping device 5, as an alternative, the air path system of this embodiment may further include: the position detecting module 10, and, as shown in fig. 6, the position detecting module 10 is disposed on the inner side surface of the tub 8 and between the tub mouth 81 and the tub bottom 82 of the tub 8. In addition, as shown in fig. 7, the position detection module 10 is also connected with the main control module in a communication manner. In practical application, the position detection module 10 is used for detecting whether the garbage bag 100 exists at a preset position between the bung 81 and the bung bottom 82 after the first vacuumizing device 4 is opened, and once the position detection module detects the garbage bag 100 at the preset position, the second vacuumizing device 5 can be opened by the main control module.
In addition, in the present embodiment, as shown in fig. 6 and 7, the position detection module 10 may specifically include: the light emitting end 101 and the light receiving end 101, wherein the light emitting end 101 and the light receiving end 102 may be disposed on the inner side of the barrel body 1 along the radial direction of the barrel body 8. Meanwhile, the position detection module 10 further includes: the controller is electrically connected with the light emitting end 101, the light receiving end 102 and the main control module respectively, and in practical application, the main control module can open the position detection module 10 after the first vacuumizing device 4 starts to work, so that the light emitting end 101 of the position detection module 10 can emit light along the radial direction of the barrel body 8, when the light receiving end 102 receives the light emitted by the light emitting end 101, the dust bag 100 is not paved at a preset position in the barrel body 8, and when the light receiving end 102 receives the light emitted by the light emitting end 101, the dust bag 100 is paved at a preset position in the barrel body 8, at the moment, an electric signal can be output to the main control module by the controller, and when the main control module receives the electric signal output by the controller, the second vacuumizing device 5 can be opened, so that the second vacuumizing device 5 can achieve the purpose of dust collection by means of a dust collection pipeline, and the dust collection nozzle 6.
As can be seen from the above, the air path system according to the present embodiment can also enable the main control module to sequentially control the opening sequence of the first vacuumizing device 4 and the second vacuumizing device 5 by detecting the laying position of the garbage bag 100 through the position detecting module 10.
In addition, the dust suction pipe 1 may be blocked in the dust suction process, so that the dust suction nozzle 6 cannot generate expected negative pressure, and the garbage can cannot achieve the expected dust suction effect. Therefore, as a preferable aspect, as shown in fig. 7, the wind path system of the present embodiment further includes: the flow detection module is arranged at the air outlet end 12 of the dust collection pipeline 1, and is electrically connected with the main control module as shown in fig. 7; the flow detection module is used for detecting the flow speed of the air flow passing through the dust collection pipeline 1. In practical application, when the second vacuumizing device 5 is turned on, the main control module is further configured to increase the power of the second vacuumizing device 5 within a preset time period when the flow rate of the air flow detected by the flow detection module is smaller than a preset flow rate. Therefore, it is not difficult to find out that when the dust collection pipeline 1 is blocked, the trafficability of the air flow through the dust collection pipeline 1 is affected, so that the flow rate of the air flow is reduced, and therefore, once the flow rate detection module detects that the flow rate of the air flow is smaller than the preset flow rate, the main control module can improve the power of the second vacuumizing device 5, so that the negative pressure of the dust collection pipeline 1 is improved, the negative pressure of the dust collection nozzle 6 is ensured, and meanwhile, the blocking object blocked in the dust collection pipeline 1 is automatically discharged into the dust-air separation box 7 through the higher negative pressure in the dust collection pipeline 1.
Therefore, the flow detection module in the air path system of the embodiment can solve the problem that the dust collection pipeline 1 is blocked to a certain extent, so that the practicability of the garbage can is effectively improved.
Example III
A third embodiment of the invention is directed to a trash can comprising: a tub 8, a base 9, a dust-gas separation box 7, and an air path system as described in the first or second embodiment.
Wherein, staving 8 has along predetermineeing the axis direction: a bung 81, a bung bottom 82 opposite to the bung 81, and a garbage bag is laid in the barrel 8. Next, the base 9 is disposed at the bottom 82 of the tub 8, and the base 9 is provided with the suction nozzle 6 around a predetermined axis direction.
In addition, the dust-gas separation box 7 is provided to the bung 81 of the tub 8, and the dust-gas separation box 7 forms an air passage 73 communicating with the bung 81 in a preset axis direction. As shown in fig. 8 and 9, the dust-gas separation box 7 includes: an inner side wall 74 provided around the air passage 73, an outer side wall 75 opposite to the inner side wall 74, top and bottom plates 76 and 77 connecting the inner side wall 74 and the outer side wall 75, an air outlet passage 71 and an air return passage 72 provided between the inner side wall 74 and the outer side wall 75.
Also, note that, in the present embodiment, as shown in fig. 8 and 9, the outlet passage 71 has: an air outlet 711 provided on the inner side wall, and an air inlet 712 provided on the bottom plate 77. And the return air passage 72 has: an air return hole 721 provided in the inner sidewall 74, and an air discharge hole 722 provided in the bottom plate 77.
Finally, in the present embodiment, as shown in fig. 8 and 9, the air return end 21 of the air discharge duct 2 in the air path system is connected to the air discharge hole 722 of the air return passage 72, and the air discharge end 12 of the dust suction duct 1 in the air path system is connected to the air intake hole 712 of the air discharge passage 71.
From the above, it is apparent that, since the garbage can is laid and sucked by the first vacuum pumping device 4 and the second vacuum pumping device 5 for the garbage bag, the negative pressure is respectively provided to the laying pipeline 3 and the suction pipeline 1, so that the garbage can has both the laying performance of the garbage bag and the suction performance. In addition, when the laying pipeline 3 lays the garbage bag, the second vacuumizing device 5 can generate air flow entering the air outlet channel 71, so that the air outlet channel 71 can exhaust dust particles into the barrel body 8 and can also exhaust the dust particles into the barrel body 8, and therefore, the laying speed of the garbage bag in the barrel body can be further accelerated by virtue of the air flow exhausted into the barrel body by the air outlet channel 71, and the garbage bag can be laid in the barrel body 8 in a short time.
Example IV
A fourth embodiment of the present invention relates to a method for laying a garbage bag using the garbage can according to the second embodiment, as shown in fig. 10, comprising the steps of:
and step 810, receiving a garbage bag paving instruction by the main control module.
In step 820, the main control module opens the first vacuumizing device 4 according to the received garbage bag paving instruction, so that the paving pipeline 3 generates an air flow entering the barrel body 8 through the barrel opening 81 of the barrel body 8.
In step 830, the main control module determines whether the dust-gas separation box 7 is installed at the bung hole 81 of the bung body 8 according to the received garbage bag laying instruction.
In step 840, if the main control module determines that the dust-air separation box 8 is installed at the bung 81 of the barrel 8, the main control module opens the second vacuumizing device 5 according to the received garbage bag laying command, so that the vacuum nozzle 6 forms negative pressure, and generates air flow entering the air outlet channel 71 through the vacuum pipeline 1, and simultaneously causes redundant air flow in the barrel 8 of the garbage can to enter the exhaust pipeline 2 through the air return channel 72.
From the above, it is apparent that, since the second vacuumizing device 5 can generate the air flow entering the air outlet channel 71 when the paving pipeline 3 is paving the garbage bag, so that the air outlet channel 71 can exhaust the dust particles into the barrel 8 and simultaneously exhaust the dust particles into the barrel 8, the paving speed of the garbage bag in the barrel can be further accelerated by the air flow exhausted into the barrel through the air outlet channel 71, and the garbage bag can be paved in the barrel 8 in a short time.
In addition, after the step of determining that the dust-air separation box 7 is mounted at the bung 81 of the bung 8, i.e. after step 830, and before the step of opening the second vacuumizing device 5 by the main control module according to the received garbage bag laying instruction, i.e. before step 840, as shown in fig. 10, the main control module further includes the following steps:
in step 831, the main control module calculates the air extraction duration of the first vacuum extractor 4.
In step 832, the main control module determines whether the air extraction duration of the first vacuum extractor 4 reaches a preset duration.
After determining the air extraction duration of the first vacuumizing device 4 and reaching the preset duration, the main control module executes step 840, i.e. the main control module opens the second vacuumizing device 5 according to the received garbage bag paving instruction. And after judging that the air extraction duration of the first vacuumizing device 4 does not reach the preset duration, the main control module returns to step 831.
In this embodiment, the preset time period is shorter than the time period from the bung 81 to the bottom 82 of the garbage bag. For example, a timing module may be set to time the air-extracting duration after the first vacuumizing device 4 is opened, and meanwhile, the timing module is in communication connection with the main control module and is used for uploading the time duration to the main control module in real time, and the main control module is used for opening the second vacuumizing device 5 according to the garbage bag paving instruction after the time duration timed by the timing module reaches the preset time duration.
In addition, as shown in fig. 10, after the step of determining whether the dust-gas separation box is mounted at the bung 81 of the barrel body 8, that is, after the step 830, the main control module further includes the following sub-steps:
in step 833, if the main control module determines that the dust-gas separation box 7 is not installed at the bung hole 81 of the barrel body 8, the main control module automatically generates and sends out warning information that the dust-gas separation box 7 is not installed at the bung hole 81. Thereby reach and remind the user, install dirt gas separation box 7 in the garbage bin this moment to, when the bung hole 81 department of staving 8 did not install dirt gas separation box 7, main control module can not open second evacuating device 5, make at this moment only first evacuating device 4 act on laying pipeline 3, with the laying of realization disposal bag in staving 8, can effectively avoid dust particle matter such as dust, hair to inhale in staving 8, cause the pollution to other parts in the garbage bin.

In addition, it should be noted that, after the step of opening the second vacuumizing device according to the received garbage bag paving instruction, that is, after step 840, as shown in fig. 10, the garbage bag paving method of the present embodiment further includes the following steps:
in step 850, the main control module determines whether the garbage bag has been laid on the bottom 82 of the bin 8.
In step 860, if the main control module determines that the garbage bag is already laid on the bottom 82 of the barrel 8, the first vacuumizing device 4 and the second vacuumizing device 5 are turned off, so that the garbage can complete the operations of laying the garbage bag and sucking dust. In addition, in order to enable the main control module to accurately determine whether the garbage bag is paved on the bottom 82 of the barrel 8, a detection module may be disposed at the bottom 82 of the barrel 8, where the detection module may employ, for example: the photoelectric sensor consists of a transmitting end, a receiving end and a controller. In practical application, the transmitting end and the receiving end can be oppositely arranged along the radial direction of the barrel bottom of the barrel body 8, meanwhile, the controller is respectively and electrically connected with the transmitting end, the receiving end and the main control module, and when the garbage bag is not paved on the barrel bottom 82 of the barrel body 8, the receiving end can receive the light ray signals emitted by the transmitting end; when the garbage bag is paved on the bottom 82 of the bag barrel body 8, at this time, the garbage bag can obstruct the light signal emitted by the emitting end, so that the receiving end cannot receive the light signal, and the controller can output an electric signal to the main control module, and the main control module respectively closes the first vacuumizing device 4 and the second vacuumizing device 5 according to the electric signal.
In addition, since the suction nozzle 6 is very prone to cause blockage of the suction pipeline 1 when performing the suction operation, the main control module preferably further includes the following steps after opening the second vacuumizing device 5 according to the received garbage bag laying command, i.e. after step 840, and before closing the first vacuumizing device 4 and the second vacuumizing device 5, i.e. before step 860, as shown in fig. 10:
in step 841, the main control module determines whether the dust suction pipeline 1 is blocked.
In step 842, if the main control module determines that the dust collection pipeline is blocked, the second vacuum device 5 is driven at a maximum power greater than the current standard power within a preset period. If the main control module determines that the dust suction pipeline is not blocked, the step 850 is continued.
In this embodiment, in order to enable the main control module to accurately determine whether the dust collection pipeline is blocked, step 841 specifically includes;
the main control module calculates the average flow velocity of the air flow when the air flow passes through the dust collection pipeline.
If the average flow velocity of the air flow calculated by the main control module is smaller than the preset average flow velocity, the main control module judges that the dust collection pipeline 1 is blocked.
If the average flow velocity of the air flow calculated by the main control module is greater than or equal to the preset average flow velocity, the main control module judges that the dust collection pipeline 1 is not blocked.
Specifically, a flow sensor may be disposed at the air outlet end 12 of the dust collection pipe 1, and the flow rate of the air flow may be detected by the flow sensor when the air flow passes through the air outlet end 12 of the dust collection pipe 1. 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 1 at this time, and a sufficient negative pressure is provided. And once the detected airflow speed is smaller than the preset airflow speed, the negative pressure in the dust collection pipeline 1 is too small, so that the dust collection nozzle 6 loses dust collection capacity. At this time, the main control module can judge that the dust collection pipeline 1 is blocked. In addition, once the dust collection pipeline 1 is blocked, the power of the second vacuumizing device 5 can be increased by the main control module, so that the negative pressure of the dust collection pipeline 1 is increased, and the blocking object blocked in the dust collection pipeline 1 can be automatically discharged into the dust-gas separation box 7 through the higher negative pressure in the dust collection pipeline 1 while the negative pressure of the dust collection nozzle 6 is ensured.
