Abstract
Description
Technical Field
[0001] This invention relates to the field of oxygen concentrator technology, and more specifically to control methods, control devices, and computer-readable storage media for oxygen concentrators. Background Technology
[0002] With an aging population and increased health awareness, the demand for home oxygen concentrators is growing. Regular cleaning or replacement of the filter cotton is necessary to protect critical components such as the compressor and molecular sieve, thus extending the concentrator's lifespan. However, users often forget to replace the filter cotton or remove the old filter cotton and forget to install the new one, affecting both the overall lifespan of the machine and the user experience. Summary of the Invention
[0003] In view of this, the present invention provides a control method, control device and computer-readable storage medium for an oxygen concentrator to solve the problem of forgetting to replace the filter cotton or forgetting to install the new filter cotton after removing the old filter cotton.
[0004] In a first aspect, the present invention provides a control method for an oxygen concentrator, the oxygen concentrator including a storage box and a recycling box, the control method comprising:
[0005] Get the current cumulative working time of the filter cotton;
[0006] When the accumulated working time reaches the preset time, the control conveying device will convey the current filter cotton to the recycling box and convey the filter cotton in the storage box to the filter cotton installation position.
[0007] Beneficial effects: By acquiring the cumulative working time of the current filter cotton, when the cumulative working time reaches the preset time, it means that the current filter cotton has been used for a long time and needs to be replaced with a new filter cotton. At this time, the conveying device will transport the current filter cotton to the recycling box and transport the filter cotton in the storage box to the filter cotton installation position for automatic replacement. No user operation is required, which avoids users forgetting to replace the filter cotton and improves the user experience.
[0008] In one optional embodiment, a first detection structure is provided at the filter cotton installation position, the first detection structure being capable of detecting whether the filter cotton is installed in place, and the control method further includes:
[0009] Check if the filter cotton is installed correctly;
[0010] If so, reset the current accumulated working time of the filter cotton to zero and restart the timer;
[0011] If not, issue an alarm.
[0012] Beneficial effects: By setting a first detection structure at the filter cotton installation position, after the filter cotton is replaced, it is detected whether the filter cotton is installed in place. If it is installed in place, the current cumulative working time of the filter cotton is reset to zero and the timer is restarted. If it is not installed in place, an alarm is issued to remind the user that the filter cotton is not installed in place and needs to be adjusted, so as to avoid affecting the use effect of the oxygen concentrator due to the filter cotton not being installed in place.
[0013] In one optional embodiment, the storage box is provided with a second detection structure, which can detect whether there is filter cotton in the storage box; the recycling box is provided with a third detection structure, which can detect whether the recycling box is full; and the step of controlling the conveying device to convey the current filter cotton to the recycling box and convey the filter cotton in the storage box to the filter cotton installation position when the accumulated working time reaches a preset time includes:
[0014] When the accumulated working time reaches the preset time, it is determined whether there is filter cotton in the storage box and whether the recycling box is full;
[0015] If there is filter cotton in the storage box and the recycling box is not full, the control conveying device will convey the current filter cotton to the recycling box and convey the filter cotton in the storage box to the filter cotton installation position.
[0016] An alarm will be triggered if there is no filter cotton in the storage box and / or the recycling box is full.
[0017] Beneficial effects: When the cumulative working time of the current filter cotton reaches the preset time, the system first checks whether there is filter cotton in the storage box and whether the recycling box is full. If there is filter cotton in the storage box and the recycling box is not full, it means that a new filter cotton can be replaced and the old filter cotton can be recycled into the recycling box. At this time, the control conveyor will transport the current filter cotton to the recycling box and the filter cotton in the storage box to the filter cotton installation position. If there is no filter cotton in the storage box or the recycling box is full, it means that the replacement of the new filter cotton cannot be completed and the next operation cannot be performed, and an alarm prompt will be issued.
[0018] In an optional implementation, the control method further includes:
[0019] After powering on, check if the filter cotton is installed correctly;
[0020] If so, it will enable the entire machine to operate;
[0021] If not, issue an alarm.
[0022] Beneficial effects: Each time the oxygen concentrator is turned on, it first checks whether the filter cotton is installed in place. The machine will only run when the filter cotton is installed in place. If the filter cotton is not installed in place, the machine will not run and will issue an alarm. This can prevent the oxygen production effect from being affected when the filter cotton is not installed in place.
[0023] In one optional implementation, the first detection structure is a first photoelectric sensor detection module, including a first transmitter and a first receiver, with the first transmitter and the first receiver respectively located on both sides of the filter cotton installation position.
[0024] Beneficial effects: The first transmitter emits a light signal. Since the first transmitter and the first receiver are respectively located on both sides of the filter cotton installation position, when filter cotton is installed at the filter cotton installation position, the filter cotton is located between the first transmitter and the first receiver. The first receiver cannot receive the light signal emitted by the first transmitter or the received light signal is weak. When there is no filter cotton at the filter cotton installation position, the first receiver can receive the light signal emitted by the first transmitter normally. Therefore, the first photoelectric sensor detection module can accurately detect whether the filter cotton is installed in place.
[0025] In one optional embodiment, the oxygen generator is provided with a structural component for installing filter cotton. The structural component has a groove, and the filter cotton is installed in the groove. A first transmitter and a first receiver are provided at both the upper and lower ends of the inner wall of the groove.
[0026] Beneficial effects: When neither of the upper nor lower first receivers receives the light signal emitted by the first transmitter, or the received light signal is weak, it indicates that the filter cotton is installed correctly. When one of the first receivers does not receive the light signal emitted by the first transmitter, or the received light signal is weak, it indicates that the filter cotton is not fully installed.
[0027] In one optional embodiment, the second detection structure is a second photoelectric sensor detection module, including a second transmitter and a second receiver, with the second transmitter and the second receiver respectively located on the upper and lower sides of the storage box.
[0028] Beneficial effects: The second transmitter emits light signals. Since the second transmitter and the second receiver are located on the upper and lower sides of the storage box respectively, when there is filter cotton in the storage box, the filter cotton is located between the second transmitter and the second receiver. The second receiver cannot receive the light signal emitted by the second transmitter or the received light signal is weak. When there is no filter cotton in the storage box, the second receiver can receive the light signal emitted by the second transmitter normally. Therefore, the second photoelectric sensor detection module can accurately detect whether there is filter cotton in the storage box.
[0029] In one optional implementation, the third detection structure is a third photoelectric sensor detection module, including a third transmitter and a third receiver, which are horizontally and relatively disposed at the top of the recycling box.
[0030] Beneficial effects: The third transmitter and the third receiver are horizontally and relatively positioned at the top of the recycling box. When the filter cotton in the recycling box is full, the filter cotton at the top of the recycling box is located between the third transmitter and the third receiver. The third receiver cannot receive the light signal emitted by the third transmitter or the received light signal is weak. When the filter cotton in the recycling box is not full, the third receiver can receive the light signal emitted by the third transmitter normally. Therefore, the third photoelectric sensor detection module can accurately detect whether the filter cotton in the recycling box is full.
[0031] Secondly, the present invention also provides a control device for an oxygen concentrator, the oxygen concentrator including a storage box and a recycling box, the control device comprising:
[0032] The first acquisition module is used to acquire the current cumulative working time of the filter cotton;
[0033] The first execution module is used to control the conveying device to convey the current filter cotton to the recycling box and to convey the filter cotton in the storage box to the filter cotton installation position when the accumulated working time reaches the preset time.
[0034] Thirdly, the present invention also provides a computer-readable storage medium storing computer instructions for causing a computer to perform the control method described above. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0047] With an aging population and increased health awareness, the demand for home oxygen concentrators is growing. Regular cleaning or replacement of the filter cotton is necessary to protect critical components such as the compressor and molecular sieve, thus extending the concentrator's lifespan. However, users often forget to replace the filter cotton or remove the old filter cotton and forget to install the new one, affecting both the overall lifespan of the machine and the user experience.
[0048] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.
[0049] According to embodiments of the present invention, in a first aspect, a control method for an oxygen generator is provided, such as... Figure 1 As shown, the oxygen concentrator includes a storage box 2 and a recovery box 3, and the control method includes:
[0050] Get the current cumulative working time of filter cotton 1;
[0051] When the accumulated working time reaches the preset time, the control conveying device will convey the current filter cotton 1 to the recycling box 3, and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10.
[0052] In this embodiment, by obtaining the cumulative working time of the current filter cotton 1, when the cumulative working time reaches the preset time, it indicates that the current filter cotton 1 has been used for a long time and needs to be replaced with a new filter cotton 1. At this time, the conveying device will convey the current filter cotton 1 to the recycling box 3 and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10 for automatic replacement. No user operation is required, which avoids the user forgetting to replace the filter cotton 1 and improves the user experience.
[0053] Specifically in one embodiment, such as Figure 2 As shown, clamping and fixing parts 4 are provided on the left and right sides of the filter cotton installation position 10. The clamping and fixing parts 4 can extend or retract and hide. When the clamping and fixing parts 4 extend, they can clamp the filter cotton 1 at the filter cotton installation position 10. When the clamping and fixing parts 4 retract and hide, they lose the clamping of the filter cotton 1, and the filter cotton 1 can leave the filter cotton 1 installation position under the conveyor belt.
[0054] Further reference Figure 2 The conveying device includes an intermediate transfer zone 5, a first conveyor belt 6, a second conveyor belt 7, a third conveyor belt 8, and a fourth conveyor belt 9. The intermediate transfer zone 5 is equipped with drive motors for operating the first conveyor belt 6, the second conveyor belt 7, the third conveyor belt 8, and the fourth conveyor belt 9. The first conveyor belt 6 connects the intermediate transfer zone 5 to the filter cotton installation position 10; the second conveyor belt 7 connects the intermediate transfer zone 5 to the storage box 2; the third conveyor belt 8 is located on one side of the intermediate transfer zone 5, connecting the bottom and top of the intermediate transfer zone 5; one end of the fourth conveyor belt 9 is connected to the third conveyor belt 8 via a steering wheel 11, and the other end connects to the top of the recycling box 3; first separating gears 12 are respectively provided on both sides of the bottom of the intermediate transfer zone 5; and a third separating gear 24 is provided between the left side of the intermediate transfer zone 5 and the third conveyor belt 8.
[0055] The first conveyor belt 6 is provided with a first clamping head 14 on each of its left and right sides. The first clamping head 14 can open and close automatically and can clamp the filter cotton 1.
[0056] When waste filter cotton needs to be recycled, the two clamping and fixing structures 23 spring back and hide. The first clamping heads 14 on the two first conveyor belts 6 clamp the filter cotton 1 and drive the first conveyor belts 6 back under the reverse action of the drive motor until it enters the intermediate transfer area 5. The first rolling shaft 15 on the left side of the conveying device starts to work. At the same time, the first separating gear 12 and the third separating gear 24 rotate. The two second clamping heads 16 at the horizontal position of the third conveyor belt 8 clamp and fix the filter cotton 1, so that the filter cotton 1 enters the path of the third conveyor belt 8 and is transported under the action of the third conveyor belt 8. Then, it enters the fourth conveyor belt 9 through the action of the steering wheel 11 until the filter cotton 1 falls into the recycling box 3. At the same time, the two second clamping heads 16 at the horizontal position of the third conveyor belt 8 reverse and fall back to the bottom of the third conveyor belt 8, and repeat the same action next time.
[0057] When a new filter cotton 1 needs to be replaced, there is a sloping groove opening at the bottom of the storage box 2, and two second separating gears 13 below the sloping groove opening. The second separating gears 13, together with the pressure roller 17 and the second rolling shaft 18, drive the filter cotton 1 into the second conveyor belt 7 until it is transported into the intermediate transfer area 5. The second rolling shaft 18 of the intermediate transfer area 5 starts to work, and at the same time, the second separating gears 13 rotate. The two first clamping heads 14 on the first conveyor belt 6 clamp and fix the filter cotton 1. Under the action of the first conveyor belt 6, the filter cotton 1 enters the first conveyor belt 6 until the filter cotton 1 is transported to the position of the limiter 19 and the first conveyor belt 6 stops working. The two clamping and fixing structures 23 pop out and fix the filter cotton 1.
[0058] It should be noted that the first conveyor belt 6 is constructed with conveyor belts on the left and right sides and a hollow center. When it is conveyed to the filter cotton installation position 10, it allows air to enter the oxygen generator after passing through the filter cotton 1.
[0059] In one embodiment not shown in the figure, the conveying device may include a robotic arm. When the filter cotton 1 needs to be replaced, the robotic arm picks up the filter cotton 1 at the filter cotton installation position 10 and puts it into the recycling box 3, and picks up the filter cotton 1 in the storage box 2 and puts it into the filter cotton installation position 10.
[0060] In one embodiment, a first detection structure is provided at the filter cotton installation position 10, the first detection structure can detect whether the filter cotton 1 is installed in place, and the control method further includes:
[0061] Check if filter cotton 1 is installed correctly;
[0062] If so, reset the current accumulated working time of filter cotton 1 to zero and restart the timer;
[0063] If not, issue an alarm.
[0064] In this embodiment, a first detection structure is set at the filter cotton installation position 10. After the filter cotton 1 is replaced, it is detected whether the filter cotton 1 is installed in place. If it is installed in place, the current cumulative working time of the filter cotton 1 is reset to zero and the timing is restarted. If it is not installed in place, an alarm prompt is issued to remind the user that the filter cotton 1 is not installed in place and needs to be adjusted to avoid affecting the use effect of the oxygen generator due to the filter cotton 1 not being installed in place.
[0065] Specifically, the system acquires the cumulative working time of the current filter cotton 1. When the cumulative working time reaches the preset time, it indicates that the current filter cotton 1 has been used for the required time and needs to be replaced with a new filter cotton 1. At this time, the conveying device will transfer the current filter cotton 1 to the recycling box 3 and transfer the filter cotton 1 in the storage box 2 to the filter cotton installation position 10. The system will check whether the filter cotton 1 is installed in place. If it is installed in place, the cumulative working time of the current filter cotton 1 will be reset to zero and the timing will start again. If it is not installed in place, an alarm will be issued to prevent the user from forgetting to replace the filter cotton 1 and also to prevent the user from forgetting to install a new filter cotton 1, thus improving the user experience.
[0066] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0067] In one embodiment, a second detection structure is provided at the storage box 2, which can detect whether there is filter cotton 1 in the storage box 2. A third detection structure is provided at the recycling box 3, which can detect whether the recycling box 3 is full. When the accumulated working time reaches a preset time, the control conveying device conveys the current filter cotton 1 to the recycling box 3, and conveys the filter cotton 1 in the storage box 2 to the filter cotton installation position 10, including:
[0068] When the accumulated working time reaches the preset time, it is determined whether there is filter cotton 1 in storage box 2 and whether recycling box 3 is full;
[0069] If there is filter cotton 1 in storage box 2 and recycling box 3 is not full, the control conveying device will convey the current filter cotton 1 to recycling box 3 and convey the filter cotton 1 in storage box 2 to filter cotton installation position 10.
[0070] An alarm will be issued if there is no filter cotton 1 in storage box 2 and / or recycling box 3 is full.
[0071] In this embodiment, when the cumulative working time of the current filter cotton 1 reaches the preset time, it is first determined whether there is filter cotton 1 in the storage box 2 and whether the recycling box 3 is full. If there is filter cotton 1 in the storage box 2 and the recycling box 3 is not full, it means that a new filter cotton 1 can be replaced and the old filter cotton 1 can be recycled into the recycling box 3. At this time, the control conveying device will convey the current filter cotton 1 to the recycling box 3 and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10. If there is no filter cotton 1 in the storage box 2 or the recycling box 3 is full, it means that the replacement of the new filter cotton 1 cannot be completed and the next operation cannot be performed, and an alarm prompt is issued.
[0072] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0073] Specifically, when the accumulated working time of filter cotton 1 reaches the preset time, the system first checks whether there is filter cotton 1 in storage box 2 and whether the recycling box 3 is full. If there is filter cotton 1 in storage box 2 and recycling box 3 is not full, it means that a new filter cotton 1 can be replaced, and the old filter cotton 1 can be recycled into recycling box 3. At this time, the control conveyor will transfer the current filter cotton 1 to recycling box 3 and transfer the filter cotton 1 in storage box 2 to filter cotton installation position 10. It will then check whether filter cotton 1 is installed correctly. If it is installed correctly, the accumulated working time of the current filter cotton 1 will be reset to zero and the timer will start again. If it is not installed correctly, an alarm will be issued. If there is no filter cotton 1 in storage box 2 or recycling box 3 is full, it means that the replacement of filter cotton 1 cannot be completed, the next operation cannot be performed, and an alarm will be issued.
[0074] In one embodiment, the control method further includes:
[0075] After powering on, check if filter cotton 1 is installed correctly;
[0076] If so, it will enable the entire machine to operate;
[0077] If not, issue an alarm.
[0078] In this embodiment, the oxygen generator first checks whether the filter cotton 1 is installed in place each time it is turned on. The whole machine will only run when the filter cotton 1 is installed in place. If the filter cotton 1 is not installed in place, the whole machine will not run and will issue an alarm. This can avoid running when the filter cotton 1 is not installed in place, which would affect the oxygen generation effect.
[0079] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0080] In one embodiment, the first detection structure is a first photoelectric sensor detection module, including a first transmitter 2001 and a first receiver 2002, which are respectively located on both sides of the filter cotton installation position 10.
[0081] In this embodiment, the first transmitter 2001 emits an optical signal. Since the first transmitter 2001 and the first receiver 2002 are respectively located on both sides of the filter cotton installation position 10, when filter cotton 1 is installed at the filter cotton installation position 10, the filter cotton 1 is located between the first transmitter 2001 and the first receiver 2002. The first receiver 2002 cannot receive the optical signal emitted by the first transmitter 2001 or the received optical signal is weak. When there is no filter cotton 1 at the filter cotton installation position 10, the first receiver 2002 can normally receive the optical signal emitted by the first transmitter 2001. Therefore, the first photoelectric sensor detection module can accurately detect whether the filter cotton 1 is installed in place.
[0082] Specifically in one embodiment, such as Figure 5 As shown, the oxygen generator has a structural component 23 for installing filter cotton 1. The structural component 23 has a groove, and the filter cotton 1 is installed in the groove. A first transmitter 2001 and a first receiver 2002 are provided at both the upper and lower ends of the inner wall of the groove. That is, the first transmitter 2001 and the first receiver 2002 are respectively located on the left and right sides of the upper end of the inner wall of the groove, and the first transmitter 2001 and the first receiver 2002 are respectively located on the left and right sides of the lower end of the inner wall of the groove. When neither of the two first receivers 2002 receives the light signal emitted by the first transmitter 2001, or the received light signal is weak, it indicates that the filter cotton 1 is installed correctly. When one of the first receivers 2002 does not receive the light signal emitted by the first transmitter 2001, or the received light signal is weak, it indicates that the filter cotton 1 is not fully installed.
[0083] In one embodiment not shown in the figure, the first detection structure may be a pressure sensor, which determines whether the filter cotton 1 is installed in place by detecting whether there is pressure at the filter cotton installation position 10.
[0084] In one embodiment, such as Figure 6 As shown, the second detection structure is a second photoelectric sensor detection module, including a second transmitter 2101 and a second receiver 2102, which are respectively located on the upper and lower sides of the storage box 2.
[0085] In this embodiment, the second transmitter 2101 emits an optical signal. Since the second transmitter 2101 and the second receiver 2102 are respectively located on the upper and lower sides of the storage box 2, when there is filter cotton 1 in the storage box 2, the filter cotton 1 is located between the second transmitter 2101 and the second receiver 2102. The second receiver 2102 cannot receive the optical signal emitted by the second transmitter 2101 or the received optical signal is weak. When there is no filter cotton 1 in the storage box 2, the second receiver 2102 can normally receive the optical signal emitted by the second transmitter 2101. Therefore, the second photoelectric sensor detection module can accurately detect whether there is filter cotton 1 in the storage box 2.
[0086] In one embodiment not shown in the figure, the second detection structure can be a weight sensor, which determines whether there is filter cotton 1 in the storage box 2 by detecting the weight of the storage box 2.
[0087] In one embodiment, such as Figure 7 As shown, the third detection structure is a third photoelectric sensor detection module, including a third transmitter 2201 and a third receiver 2202, which are horizontally and relatively disposed at the top of the recycling box 3.
[0088] In this embodiment, the third transmitter 2201 and the third receiver 2202 are horizontally and oppositely disposed at the top of the recycling box 3. When the filter cotton 1 in the recycling box 3 is full, the filter cotton 1 at the top of the recycling box 3 is located between the third transmitter 2201 and the third receiver 2202. The third receiver 2202 cannot receive the light signal emitted by the third transmitter 2201 or the received light signal is weak. When the filter cotton 1 in the recycling box 3 is not full, the third receiver 2202 can normally receive the light signal emitted by the third transmitter 2201. Therefore, the third photoelectric sensor detection module can accurately detect whether the filter cotton 1 in the recycling box 3 is full.
[0089] In one embodiment not shown in the figure, the third detection structure may be a weight sensor, which determines whether the filter cotton 1 inside the recycling box 3 is full by detecting the weight of the recycling box 3.
[0090] According to an embodiment of the present invention, in a second aspect, a control device for an oxygen concentrator is provided. The oxygen concentrator includes a storage box 2 and a recovery box 3. The control device includes:
[0091] The first acquisition module is used to acquire the cumulative working time of the current filter cotton 1;
[0092] The first execution module is used to control the conveying device to convey the current filter cotton 1 to the recycling box 3 and to convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10 when the accumulated working time reaches the preset time.
[0093] In this embodiment, the first acquisition module obtains the cumulative working time of the current filter cotton 1. When the cumulative working time reaches the preset time, it means that the current filter cotton 1 has been used for a long time and needs to be replaced with a new filter cotton 1. At this time, the first execution module controls the conveying device to convey the current filter cotton 1 to the recycling box 3 and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10 for automatic replacement. No user operation is required, which avoids the user forgetting to replace the filter cotton 1 and improves the user experience.
[0094] Specifically in one embodiment, such as Figure 2As shown, clamping and fixing parts 4 are provided on the left and right sides of the filter cotton installation position 10. The clamping and fixing parts 4 can extend or retract and hide. When the clamping and fixing parts 4 extend, they can clamp the filter cotton 1 at the filter cotton installation position 10. When the clamping and fixing parts 4 retract and hide, they lose the clamping of the filter cotton 1, and the filter cotton 1 can leave the filter cotton 1 installation position under the conveyor belt.
[0095] Further reference Figure 2 The conveying device includes an intermediate transfer zone 5, a first conveyor belt 6, a second conveyor belt 7, a third conveyor belt 8, and a fourth conveyor belt 9. The intermediate transfer zone 5 is equipped with drive motors for operating the first conveyor belt 6, the second conveyor belt 7, the third conveyor belt 8, and the fourth conveyor belt 9. The first conveyor belt 6 connects the intermediate transfer zone 5 to the filter cotton installation position 10; the second conveyor belt 7 connects the intermediate transfer zone 5 to the storage box 2; the third conveyor belt 8 is located on one side of the intermediate transfer zone 5, connecting the bottom and top of the intermediate transfer zone 5; one end of the fourth conveyor belt 9 is connected to the third conveyor belt 8 via a steering wheel 11, and the other end connects to the top of the recycling box 3; separation gears are respectively provided on both sides of the bottom of the intermediate transfer zone 5.
[0096] The first conveyor belt 6 is provided with a first clamping head 14 on each of its left and right sides. The first clamping head 14 can open and close automatically and can clamp the filter cotton 1.
[0097] When waste filter cotton needs to be recycled, the two clamping and fixing structures 23 spring back and hide. The first clamping heads 14 on the two first conveyor belts 6 clamp the filter cotton 1 and drive the first conveyor belts 6 back under the reverse action of the drive motor until it enters the intermediate transfer area 5. The first rolling shaft 15 on the left side of the conveying device starts to work. At the same time, the first separating gear 12 rotates and the two second clamping heads 16 at the horizontal position of the third conveyor belt 8 clamp and fix the filter cotton 1, so that the filter cotton 1 enters the path of the third conveyor belt 8 and is transported under the action of the third conveyor belt 8. Then, it enters the fourth conveyor belt 9 through the action of the steering wheel 11 until the filter cotton 1 falls into the recycling box 3. At the same time, the two second clamping heads 16 at the horizontal position of the third conveyor belt 8 reverse and fall back to the bottom of the third conveyor belt 8, and repeat the same action next time.
[0098] When a new filter cotton 1 needs to be replaced, there is a sloping groove opening at the bottom of the storage box 2, and two second separating gears 13 below the sloping groove opening. The second separating gears 13, together with the pressure roller 17 and the second rolling shaft 18, drive the filter cotton 1 into the second conveyor belt 7 until it is transported into the intermediate transfer area 5. The second rolling shaft 18 of the intermediate transfer area 5 starts to work, and at the same time, the second separating gears 13 rotate. The two first clamping heads 14 on the first conveyor belt 6 clamp and fix the filter cotton 1. Under the action of the first conveyor belt 6, the filter cotton 1 enters the first conveyor belt 6 until the filter cotton 1 is transported to the position of the limiter 19 and the first conveyor belt 6 stops working. The two clamping and fixing structures 23 pop out and fix the filter cotton 1.
[0099] It should be noted that the first conveyor belt 6 is constructed with conveyor belts on the left and right sides and a hollow center. When it is conveyed to the filter cotton installation position 10, it allows air to enter the oxygen generator after passing through the filter cotton 1.
[0100] In one embodiment not shown in the figure, the conveying device may include a robotic arm. When the filter cotton 1 needs to be replaced, the robotic arm picks up the filter cotton 1 at the filter cotton installation position 10 and puts it into the recycling box 3, and picks up the filter cotton 1 in the storage box 2 and puts it into the filter cotton installation position 10.
[0101] In one embodiment, a first detection structure is provided at the filter cotton installation position 10, the first detection structure being able to detect whether the filter cotton 1 is installed in place, and the control device further includes:
[0102] The first detection module is used to detect whether filter cotton 1 is installed in place;
[0103] The second execution module is used to reset the current cumulative working time of filter cotton 1 to zero and restart the timing when filter cotton 1 is installed in place;
[0104] The third execution module is used to issue an alarm when filter cotton 1 is not installed in place.
[0105] In this embodiment, a first detection structure is set at the filter cotton installation position 10. After the filter cotton 1 is replaced, it is detected whether the filter cotton 1 is installed in place. If it is installed in place, the current cumulative working time of the filter cotton 1 is reset to zero and the timing is restarted. If it is not installed in place, an alarm prompt is issued to remind the user that the filter cotton 1 is not installed in place and needs to be adjusted to avoid affecting the use effect of the oxygen generator due to the filter cotton 1 not being installed in place.
[0106] Specifically, the first acquisition module acquires the cumulative working time of the current filter cotton 1. When the cumulative working time reaches the preset time, it means that the current filter cotton 1 has been used for a long time and needs to be replaced with a new filter cotton 1. At this time, the first execution module controls the conveying device to convey the current filter cotton 1 to the recycling box 3 and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10. The first detection module detects whether the filter cotton 1 is installed in place. If it is installed in place, the second execution module resets the cumulative working time of the current filter cotton 1 to zero and restarts the timing. If it is not installed in place, the third execution module issues an alarm prompt to prevent the user from forgetting to replace the filter cotton 1 and also to prevent the user from forgetting to install a new filter cotton 1, thus improving the user experience.
[0107] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0108] In one embodiment, the storage box 2 is provided with a second detection structure, which can detect whether there is filter cotton 1 in the storage box 2, and the recycling box 3 is provided with a third detection structure, which can detect whether the recycling box 3 is full. The first execution module specifically includes:
[0109] The first judgment module is used to determine whether there is filter cotton 1 in the storage box 2 and whether the recycling box 3 is full when the accumulated working time reaches the preset time.
[0110] The first execution submodule is used to control the conveying device to convey the current filter cotton 1 to the recycling box 3 and to convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10 when there is filter cotton 1 in the storage box 2 and the recycling box 3 is not full.
[0111] The second execution submodule is used to issue an alarm when there is no filter cotton 1 in the storage box 2 and / or the recycling box 3 is full.
[0112] In this embodiment, when the cumulative working time of the current filter cotton 1 reaches the preset time, the first judgment module first determines whether there is filter cotton 1 in the storage box 2 and whether the recycling box 3 is full. When there is filter cotton 1 in the storage box 2 and the recycling box 3 is not full, it means that a new filter cotton 1 can be replaced and the old filter cotton 1 can be recycled into the recycling box 3. At this time, the first execution submodule controls the conveying device to convey the current filter cotton 1 to the recycling box 3 and convey the filter cotton 1 in the storage box 2 to the filter cotton installation position 10. If there is no filter cotton 1 in the storage box 2 or the recycling box 3 is full, it means that the replacement of the new filter cotton 1 cannot be completed and the next operation cannot be performed. The second execution submodule issues an alarm prompt.
[0113] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0114] Specifically, when the accumulated working time of filter cotton 1 reaches the preset time, the first judgment submodule first determines whether there is filter cotton 1 in storage box 2 and whether the recycling box 3 is full. If there is filter cotton 1 in storage box 2 and recycling box 3 is not full, it means that a new filter cotton 1 can be replaced, and the old filter cotton 1 can be recycled into recycling box 3. At this time, the first execution submodule controls the conveying device to convey the current filter cotton 1 to recycling box 3 and convey the filter cotton 1 in storage box 2 to filter cotton installation position 10. The first detection module detects whether filter cotton 1 is installed in place. If it is installed in place, the second execution module resets the accumulated working time of the current filter cotton 1 to zero and restarts the timing. If it is not installed in place, the third execution module issues an alarm prompt. If there is no filter cotton 1 in storage box 2 or recycling box 3 is full, it means that the replacement of new filter cotton 1 cannot be completed and the next operation cannot be performed. The second execution submodule issues an alarm prompt.
[0115] In one embodiment, the first detection module is further configured to detect whether the filter cotton 1 is installed in place after power-on, and the control device further includes:
[0116] The fourth execution module is used to make the whole machine run when the filter cotton 1 is installed in place;
[0117] The fifth execution module is used to issue an alarm when filter cotton 1 is not installed in place.
[0118] In this embodiment, the oxygen generator first checks whether the filter cotton 1 is installed in place each time it is turned on. The whole machine will only run when the filter cotton 1 is installed in place. If the filter cotton 1 is not installed in place, the whole machine will not run and will issue an alarm. This can avoid running when the filter cotton 1 is not installed in place, which would affect the oxygen generation effect.
[0119] Specifically, alarm prompts can be issued through an audible sound from a buzzer or by displaying a fault code.
[0120] In one embodiment, the first detection structure is a first photoelectric sensor detection module, including a first transmitter 2001 and a first receiver 2002, which are respectively located on both sides of the filter cotton installation position 10.
[0121] In this embodiment, the first transmitter 2001 emits an optical signal. Since the first transmitter 2001 and the first receiver 2002 are respectively located on both sides of the filter cotton installation position 10, when filter cotton 1 is installed at the filter cotton installation position 10, the filter cotton 1 is located between the first transmitter 2001 and the first receiver 2002. The first receiver 2002 cannot receive the optical signal emitted by the first transmitter 2001 or the received optical signal is weak. When there is no filter cotton 1 at the filter cotton installation position 10, the first receiver 2002 can normally receive the optical signal emitted by the first transmitter 2001. Therefore, the first photoelectric sensor detection module can accurately detect whether the filter cotton 1 is installed in place.
[0122] Specifically in one embodiment, such as Figure 5As shown, the oxygen generator has a structural component 23 for installing filter cotton 1. The structural component 23 has a groove, and the filter cotton 1 is installed in the groove. A first transmitter 2001 and a first receiver 2002 are provided at both the upper and lower ends of the inner wall of the groove. That is, the first transmitter 2001 and the first receiver 2002 are respectively located on the left and right sides of the upper end of the inner wall of the groove, and the first transmitter 2001 and the first receiver 2002 are respectively located on the left and right sides of the lower end of the inner wall of the groove. When neither of the two first receivers 2002 receives the light signal emitted by the first transmitter 2001, or the received light signal is weak, it indicates that the filter cotton 1 is installed correctly. When one of the first receivers 2002 does not receive the light signal emitted by the first transmitter 2001, or the received light signal is weak, it indicates that the filter cotton 1 is not fully installed.
[0123] In one embodiment not shown in the figure, the first detection structure may be a pressure sensor, which determines whether the filter cotton 1 is installed in place by detecting whether there is pressure at the filter cotton installation position 10.
[0124] In one embodiment, the second detection structure is a second photoelectric sensor detection module, including a second transmitter 2101 and a second receiver 2102, with the second transmitter 2101 and the second receiver 2102 respectively disposed on the upper and lower sides of the storage box 2.
[0125] In this embodiment, the second transmitter 2101 emits an optical signal. Since the second transmitter 2101 and the second receiver 2102 are respectively located on the upper and lower sides of the storage box 2, when there is filter cotton 1 in the storage box 2, the filter cotton 1 is located between the second transmitter 2101 and the second receiver 2102. The second receiver 2102 cannot receive the optical signal emitted by the second transmitter 2101 or the received optical signal is weak. When there is no filter cotton 1 in the storage box 2, the second receiver 2102 can normally receive the optical signal emitted by the second transmitter 2101. Therefore, the second photoelectric sensor detection module can accurately detect whether there is filter cotton 1 in the storage box 2.
[0126] In one embodiment not shown in the figure, the second detection structure can be a weight sensor, which determines whether there is filter cotton 1 in the storage box 2 by detecting the weight of the storage box 2.
[0127] In one embodiment, the third detection structure is a third photoelectric sensor detection module, including a third transmitter 2201 and a third receiver 2202, which are horizontally and relatively disposed at the top of the recycling box 3.
[0128] In this embodiment, the third transmitter 2201 and the third receiver 2202 are horizontally and oppositely disposed at the top of the recycling box 3. When the filter cotton 1 in the recycling box 3 is full, the filter cotton 1 at the top of the recycling box 3 is located between the third transmitter 2201 and the third receiver 2202. The third receiver 2202 cannot receive the light signal emitted by the third transmitter 2201 or the received light signal is weak. When the filter cotton 1 in the recycling box 3 is not full, the third receiver 2202 can normally receive the light signal emitted by the third transmitter 2201. Therefore, the third photoelectric sensor detection module can accurately detect whether the filter cotton 1 in the recycling box 3 is full.
[0129] In one embodiment not shown in the figure, the third detection structure may be a weight sensor, which determines whether the filter cotton 1 inside the recycling box 3 is full by detecting the weight of the recycling box 3.
[0130] According to an embodiment of the present invention, in a third aspect, a computer-readable storage medium is also provided, the computer-readable storage medium storing computer instructions for causing a computer to perform the control method described above.
[0131] The storage medium can be a magnetic disk, optical disk, read-only memory (ROM), random access memory (RAM), flash memory, hard disk drive (HDD), or solid-state drive (SSD), etc.; the storage medium can also include a combination of the above types of memory.
[0132] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
