Example 1
Referring to fig. 1, an embodiment of the present invention provides a detection method for a printer, the printer including a printer main body and an ink cartridge 101, the ink cartridge 101 being detachably mounted in a mounting chamber 105 of the printer main body, a signal transmitting device 106 and a signal receiving portion being provided in the mounting chamber 105 of the printer main body, the signal receiving portion being configured to receive a signal transmitted from the signal transmitting device 106, a housing chamber 102 and a detection device 103 being provided in a main body portion of the ink cartridge 101, the housing chamber 102 housing ink, the detection device 103 being configured to enable the signal receiving portion to receive the signal when the ink cartridge 101 reaches a set position in the mounting chamber 105 and a liquid level of the ink in the housing chamber 102 has a first set value, and the detection device 103 being configured to disable the signal receiving portion to receive the signal when the ink cartridge 101 reaches the set position in the mounting chamber 105 and the liquid level of the ink in the housing chamber 102 has a second set value, the second set value being larger than the first set value, the detection method for a printer comprising:
Step S101, adjusting the liquid level of the ink in the accommodating chamber 102 so that the liquid level has the first set value.
Thus, when the ink cartridge 101 reaches the set position in the mounting chamber 105, the detection device 103 can cause the signal receiving portion to receive a signal if the detection device 103 is in a normal state, thereby preparing for detection by the detection device 103.
Step S201, moving the ink cartridge 101 to a set position in the mounting chamber 105, and detecting whether the signal receiving portion receives the signal.
At this time, the signal receiving unit indicates that the detection device 103 is in a normal state when receiving a signal, and indicates that the detection device 103 is in an abnormal state when not receiving a signal, whereby detection of the detection device 103 can be achieved.
Preferably, the ink cartridge 101 reaches the set position in a state of being mounted in place. Thus, the detection of the detection device 103 is realized in the state where the ink cartridge 101 is in place, and the ink cartridge 101 is positioned relative to the printer main body in the state where the ink cartridge 101 is in place, so that the stability and accuracy of the detection are improved.
Preferably, the ink cartridge 101 reaches the set position during loading into the mounting cavity 105. Thus, detection of the detecting device 103 is achieved during the mounting of the ink cartridge 101, and when the detection result of the detecting device 103 is abnormal, use of the ink cartridge 101 can be stopped or maintenance of the ink cartridge 101 can be performed, so that the subsequent unnecessary mounting operation can be omitted.
In step S301, the liquid level of the ink in the accommodating chamber 102 is adjusted so that the liquid level reaches the second set value.
At this time, if the signal receiving portion cannot receive the signal, it is indicated that the liquid level of the ink in the accommodating chamber 102 reaches the second set value. The second set value may be a liquid level of the ink in the accommodating cavity 102 in a full state, so that when the signal receiving portion cannot receive the signal, it may be indicated that the ink in the accommodating cavity 102 reaches the full state, thereby completing detection of the full state of the ink.
Since the detection device 103 can be detected before the detection of the full ink state is performed, when the detection result of the detection device 103 is in an abnormal state, the use of the ink cartridge 101 can be stopped or the maintenance of the ink cartridge 101 can be performed, so that the influence on the subsequent printing operation can be avoided, and the reliability of the printer can be improved.
Example two

In this embodiment, since the liquid level of the ink in the accommodation chamber 102 has the first set value in the initial state, when the ink cartridge 101 reaches the set position in the mounting chamber 105, the detection device 103 can cause the signal receiving portion to receive the signal if the detection device 103 is in the normal state. In the process of loading the ink cartridge 101 into the mounting chamber 105, when the ink cartridge 101 reaches a set position in the mounting chamber 105, whether the signal receiving portion receives a signal or not can be detected, and if the signal receiving portion receives a signal, the detection device 103 is in a normal state, and if the signal receiving portion does not receive a signal, the detection device 103 is in an abnormal state, whereby detection of the detection device 103 can be achieved. After the detection by the detection device 103 is completed, the liquid level of the ink in the accommodating chamber 102 may be adjusted by the liquid level adjustment device so that the liquid level reaches the second set value, and at this time, if the signal receiving portion cannot receive the signal, it is indicated that the liquid level of the ink in the accommodating chamber 102 reaches the second set value. The second set value may be a liquid level of the ink in the accommodating cavity 102 in a full state, so that when the signal receiving portion cannot receive the signal, it may be indicated that the ink in the accommodating cavity 102 reaches the full state, thereby completing detection of the full state of the ink. Since the detection device 103 can be detected before the detection of the full ink state is performed, when the detection result of the detection device 103 is in an abnormal state, the use of the ink cartridge 101 can be stopped or the maintenance of the ink cartridge 101 can be performed, so that the influence on the subsequent printing operation can be avoided, and the reliability of the printer can be improved.
In the present embodiment, it is preferable that the ink cartridge 101 reaches the set position in a state of being mounted in place. Thus, the detection of the detection device 103 is realized in the state where the ink cartridge 101 is in place, and the ink cartridge 101 is positioned relative to the printer main body in the state where the ink cartridge 101 is in place, so that the stability and accuracy of the detection are improved.
Referring to fig. 6 and 7, in the present embodiment, the setting positions preferably include a first setting position and a second setting position, the first setting position and the second setting position are disposed at intervals along the length direction of the mounting cavity 105, the ink cartridge 101 reaches the first setting position during the process of being mounted in the mounting cavity 105, and the ink cartridge 101 reaches the second setting position in a state of being mounted in place; the liquid level adjustment device 104 is configured to adjust a liquid level of the ink in the accommodating chamber 102 so that the liquid level reaches the second set value when the ink cartridge 101 reaches the second set position. Thus, the ink cartridge 101 reaches the first setting position during the process of being loaded into the mounting chamber 105, and the detection of the detection device 103 can be achieved during the process of mounting the ink cartridge 101. When the detection result of the detection device 103 is an abnormal state, the use of the ink cartridge 101 may be stopped or the ink cartridge 101 may be repaired, so that the subsequent unnecessary mounting operation can be omitted. When the detection result of the detection device 103 is a normal state, the ink cartridge 101 may be continuously installed, and the ink cartridge 101 reaches the second setting position in the installed state, and at this time, the liquid level adjustment device 104 adjusts the liquid level of the ink in the accommodating chamber 102 to the second setting value, thereby completing the detection of the full-ink state.
Referring to fig. 6 and 7, in the present embodiment, it is preferable that the signal emitting device 106 includes a first emitting portion 107 and a second emitting portion 108, where the first emitting portion 107 and the second emitting portion 108 are sequentially disposed along the length direction of the mounting cavity 105, the first emitting portion 107 is configured to emit the signal to the detecting device 103 when the ink cartridge 101 reaches the first setting position, and the second emitting portion 108 is configured to emit the signal to the detecting device 103 when the ink cartridge 101 reaches the second setting position. Thus, the detection of the detection device 103 can be achieved by detecting whether the signal receiving section receives a signal when the ink cartridge 101 reaches the first setting position, and the detection of the full ink state can be achieved by detecting whether the signal receiving section receives a signal when the ink cartridge 101 reaches the second setting position. The accuracy of detection is improved.
Example III

Thus, in the initial state, the detection device 103 is positioned above the liquid surface of the ink in the accommodating chamber 102, and therefore, when the ink cartridge 101 reaches the set position in the mounting chamber 105, the detection device 103 can receive a signal and transmit the signal to the signal receiving portion if it is in the normal state. Therefore, when the ink cartridge 101 reaches the set position in the mounting chamber 105 during the process of mounting the ink cartridge 101 in the mounting chamber 105, it is possible to detect whether the signal receiving portion receives a signal, and if the signal receiving portion receives a signal, it is indicated that the detection device 103 is in a normal state, and if the signal receiving portion does not receive a signal, it is indicated that the detection device 103 is in an abnormal state, whereby the detection of the detection device 103 can be achieved. After the detection by the detection device 103 is completed, the liquid level of the ink in the accommodating chamber 102 may be adjusted by the liquid level adjustment device so that the detection device 103 is located below the liquid level of the ink in the accommodating chamber 102, and at this time, the ink in the accommodating chamber 102 can block or change the path of the signal so that the signal cannot be received by the signal receiving portion, so that if the signal cannot be received by the signal receiving portion, it is indicated that the liquid level of the ink in the accommodating chamber 102 has reached the second set value.
Example IV
Referring to fig. 4 and 5, in the second embodiment, the detecting device 103 includes a baffle 109, where the baffle 109 is configured to reach a first position when a liquid level of ink in the accommodating chamber 102 has the first set value, so that the baffle 109 can avoid the signal when the ink cartridge 101 reaches the set position in the mounting chamber 105, and the signal receiving portion can receive the signal; the shutter 109 is configured to reach a second position when the liquid level of the ink in the accommodating chamber 102 has the second set value, so that the shutter 109 can block or change the path of the signal when the ink cartridge 101 reaches the set position in the mounting chamber 105, so that the signal cannot be received by the signal receiving section. Thus, when the detection device 103 is in a normal state, the shutter 109 is in the first position in the initial state, and when the ink cartridge 101 reaches the set position in the mounting chamber 105, the shutter 109 can avoid the signal, so that the signal can be transmitted to the signal receiving portion. Therefore, when the ink cartridge 101 reaches the set position in the mounting chamber 105 during the process of mounting the ink cartridge 101 in the mounting chamber 105, it is possible to detect whether the signal receiving portion receives a signal, and if the signal receiving portion receives a signal, it is indicated that the detection device 103 is in a normal state, and if the signal receiving portion does not receive a signal, it is indicated that the detection device 103 is in an abnormal state, whereby the detection of the detection device 103 can be achieved. When the detection by the detection device 103 is completed and the detection result by the detection device 103 is in a normal state, the liquid level of the ink in the accommodating chamber 102 can be adjusted by the liquid level adjustment device so that the shutter 109 reaches the second position, and at this time, the shutter 109 can block or change the path of the signal so that the signal cannot be received by the signal receiving portion, so that if the signal cannot be received by the signal receiving portion, it is indicated that the liquid level of the ink in the accommodating chamber 102 reaches the second set value.

In this embodiment, since the liquid level of the ink in the accommodation chamber 102 has the first set value in the initial state, when the ink cartridge 101 reaches the set position in the mounting chamber 105, the detection device 103 can cause the signal receiving portion to receive the signal if the detection device 103 is in the normal state. In the process of loading the ink cartridge 101 into the mounting chamber 105, when the ink cartridge 101 reaches a set position in the mounting chamber 105, whether the signal receiving portion receives a signal or not can be detected, and if the signal receiving portion receives a signal, the detection device 103 is in a normal state, and if the signal receiving portion does not receive a signal, the detection device 103 is in an abnormal state, whereby detection of the detection device 103 can be achieved. After the detection by the detection device 103 is completed, the liquid level of the ink in the accommodating chamber 102 may be adjusted so that the liquid level reaches the second set value, and at this time, if the signal receiving portion cannot receive the signal, it is indicated that the liquid level of the ink in the accommodating chamber 102 reaches the second set value. The second set value may be a liquid level of the ink in the accommodating cavity 102 in a full state, so that when the signal receiving portion cannot receive the signal, it may be indicated that the ink in the accommodating cavity 102 reaches the full state, thereby completing detection of the full state of the ink. Since the detection device 103 can be detected before the detection of the full ink state is performed, when the detection result of the detection device 103 is in an abnormal state, the use of the ink cartridge 101 can be stopped or the maintenance of the ink cartridge 101 can be performed, so that the influence on the subsequent printing operation can be avoided, and the reliability of the printer can be improved.
