Description
Technical Field
[0001] The present invention relates to the field of clothing processing devices, and in particular to a clothing processing device and a control method for the clothing processing device. Background Art
[0002] Laundry handling devices are common household appliances, and a variety of them bring numerous conveniences to people's lives. In daily use, users must open the door, place clothes into the laundry inlet, then close the door and start the cycle. However, in practice, the door often remains open, or users close the door before fully inserting clothes into the laundry inlet.
[0003] If the door is not closed tightly or a program is started after clothes are trapped between the machine body and the door, the rotation of the drum will inevitably pull on the trapped clothes, causing damage to the clothes. Furthermore, the trapped clothes will also squeeze the machine body and door, causing deformation and wear. Therefore, users should check whether the clothes are properly placed after loading.
[0004] However, after closing the door, users often have no idea whether it's fully closed, let alone whether clothes are trapped in it. This is especially true for front-loading washing machines, such as drum washing machines, where the loading opening is located relatively low, making it inconvenient for users to bend down and check. Therefore, a clothing handling device that can detect whether the door is closed is urgently needed.
[0005] In view of this, the present invention is proposed. Summary of the Invention

[0043] At the same time, if the machine door is not closed tightly or laundry is clamped between the machine door and the machine body, there will be no direct contact between the first conductor and the second conductor, and there will even be a certain gap between the first conductor and the second conductor. In this way, due to the reduction in the contact area between the first conductor and the second conductor, the electrical signal strength of the conductive circuit is reduced, so that it is possible to judge whether the machine door is closed tightly and whether the machine door clamps laundry based on the conductivity of the conductive circuit. There is no need for the user to look through the door and window to check whether the laundry is clamped by the machine door, which ensures that the laundry is put in place and avoids the situation where the clothing processing device is activated when the laundry is clamped between the machine door and the machine body, causing damage to the laundry, the machine body, and the machine door, thereby improving the user experience and the service life of the product.
[0044] In general, the conductive circuit of the present invention has a simple structure, is easy to assemble, has low cost, and is easy to promote. It can accurately determine the conductivity of the conductive circuit. If the electrical signal of the conductive circuit is absent or the intensity is reduced, the clothing processing device is controlled to suspend operation to avoid damage to the laundry, the machine door, and the machine body.

DETAILED DESCRIPTION
[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0062] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.
[0063] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0064] The present invention will be further described in detail below with reference to the embodiments.
[0065] The present invention provides a clothes processing device 100. For example, the clothes processing device 100 can be a drum washing machine, a pulsator washing machine, a dryer, a washer-dryer, etc., without specific limitation herein. The present invention is particularly applicable to a front-opening clothes processing device 100.
[0066] The following is a detailed explanation using a drum washing machine as an example. Figure 1 and Figure 2 As shown, the drum washing machine includes a body 110 and a door 120. Specifically, the body 110 includes multiple system modules such as a box module, a front panel 113 module, a drum module, and a control module. The drum module is arranged in the box module. The drum module is used to hold laundry and washing water. The front panel 113 module is connected to the box module. The front panel 113 module and the box module together constitute the clothing loading port 111 of the drum washing machine. The control module is used to control the operation of the drum washing machine.
[0067] In detail, such as Figure 3 、 Figure 4 and Figure 9 As shown, the machine body 110 has a clothing inlet 111, and a first conductor 112 is provided on the machine body 110. A door 120 is openably and closably provided at the clothing inlet 111, and a second conductor 121 is provided on the door 120. The clothing processing device 100 also includes a power supply 130, and the first conductor 112 and the second conductor 121 are electrically connected to the power supply 130 respectively. When the door 120 closes the clothing inlet 111, the first conductor 112 and the second conductor 121 are at least partially in contact, so that the first conductor 112, the second conductor 121, and the power supply 130 form a conductive loop.
[0068] In the clothing processing device 100 provided by the present invention, the first conductor 112 and the second conductor 121 are respectively electrically connected to the power supply device 130. In this way, when the machine door 120 closes the clothing input port 111, the first conductor 112 and the second conductor 121 are at least partially in contact, so that the conductive circuit is conductive. When the machine door 120 opens the clothing input port 111, the first conductor 112 and the second conductor 121 are separated, so that the conductive circuit is disconnected, thereby realizing the judgment of the open and closed state of the machine door 120 based on the on-off state of the conductive circuit.
[0069] At the same time, if the machine door 120 is not closed tightly or laundry is clamped between the machine door 120 and the machine body 110, there will be no direct contact between the first conductor 112 and the second conductor 121, and there may even be a certain gap between the first conductor 112 and the second conductor 121. In this way, due to the reduction in the contact area between the first conductor 112 and the second conductor 121, the electrical signal strength of the conductive circuit is reduced, so that whether the machine door 120 is closed tightly and whether laundry is clamped by the machine door 120 can be judged according to the conductivity of the conductive circuit. The user does not need to look through the door window 122 to check whether the laundry is clamped by the machine door 120, thereby ensuring that the laundry is put in place and avoiding the situation where the clothing processing device 100 is started when laundry is clamped between the machine door 120 and the machine body 110, causing damage to the laundry, the machine body 110, and the machine door 120, thereby improving the user experience and the service life of the product.
[0070] In general, the conductive circuit of the present invention has a simple structure, is easy to assemble, has low cost, and is easy to promote. It can accurately determine the conductivity of the conductive circuit. If the electrical signal of the conductive circuit is absent or the intensity is reduced, the clothing processing device 100 is controlled to suspend work to avoid damage to the laundry, the machine door 120, and the machine body 110.
[0071] It is worth noting that the present invention can also be applied to detecting the compatibility between the door 120 and the body 110. For example, during the production and assembly phase, the use phase, or the maintenance phase of the product, the operator closes the door 120 and checks the electrical signal of the conductive circuit to determine the compatibility between the door 120 and the body 110. If the electrical signal of the conductive circuit exceeds a preset threshold, it indicates that the door 120 and the body 110 are not properly compatible, the sealing is poor, and there is a risk of water (wind) leakage.
[0072] In some embodiments, as Figure 7 and Figure 8 As shown, the first conductor 112 is provided on the machine body 110 and extends along the circumference of the clothing inlet 111 .
[0073] In some embodiments, as Figure 5 and Figure 6 As shown, the second conductor 121 is disposed on the door 120 and extends along the circumference of the door 120 .
[0074] Preferably, at least a portion of the first conductive body 112 is disposed opposite to the second conductive body 121 .
[0075] For example, the first conductor 112 and / or the second conductor 121 are made of a conductive material, such as one or more of metal, graphite, and a metal compound.
[0076] In some embodiments, the body 110 includes a front plate 113 having a clothing inlet 111 . A contact seal is provided on the front plate 113 in a circumferential direction surrounding the clothing inlet 111 , and the first conductor 112 is provided on the contact seal.
[0077] In this embodiment, when the machine door 120 closes the clothing loading port 111, the machine door 120 contacts and abuts against the contact seal, and the first conductor 112 is arranged on the contact seal, which is conducive to ensuring the reliability of direct contact between the first conductor 112 and the second conductor 121 and reducing errors.
[0078] Preferably, the second electrical conductor 121 contacts at least the lower region of the contact seal, and the first electrical conductor 112 is located on the lower region of the contact seal.
[0079] It can be understood that when the laundry is thrown into the drum, under the action of gravity, the laundry is more easily clamped in the lower area of the clothing inlet 111, and the second conductor 121 is arranged to contact the lower area of the contact seal, that is, the second conductor 121 is arranged in the lower area of the machine door 120, and the first conductor 112 is located in the lower area of the contact seal. While ensuring the detection of the closing status of the machine door 120 and whether the laundry is clamped, the sizes of the first conductor 112 and the second conductor 121 are relatively reduced, which reduces the difficulty of assembly and reduces the cost, and is conducive to ensuring the sealing effect of the upper part of the machine door 120.
[0080] In addition, the first conductor 112 and the second conductor 121 are respectively located in the lower area, so that the first conductor 112 and the second conductor 121 are relatively distributed, increasing the effective contact area between the two, thereby further expanding the detection area and further reducing the risk of clothing being clamped.
[0081] Preferably, the second conductor 121 contacts at least the lower half of the contact seal, and the first conductor 112 is located on the lower half of the contact seal.
[0082] In some embodiments, when the door 120 closes the clothing loading port 111 , the second conductor 121 contacts the contact seal and the first conductor 112 simultaneously.
[0083] In this embodiment, the second conductor 121 is provided to contact the seal and the first conductor 112 at the same time. In this way, while detecting the closing status of the machine door 120 and whether the laundry is clamped, the sealing effect of the machine door 120 is ensured, water leakage (wind) is avoided, and the reliability of the product is improved.
[0084] Preferably, the width of the second conductor 121 is greater than the width of the first conductor 112 , so that when the door 120 closes the clothing inlet 111 , the second conductor 121 contacts the seal and the first conductor 112 simultaneously.
[0085] In some embodiments, the peripheral wall of the front panel 113 surrounding the clothing loading port 111 is formed as a contact seal, that is, when the machine door 120 closes the clothing loading port 111, the edge of the machine door 120 contacts the front panel 113, wherein the area where the front panel 113 contacts the machine door 120 is formed as a contact seal, and the first conductor 112 is arranged in the area where the front panel 113 contacts the machine door 120.
[0086] In some embodiments, the contact seal is a window gasket 114 (or door seal) provided at the clothing loading port 111 . The window gasket 114 has a protrusion 1141 protruding from the front surface of the front plate 113 , and the first conductor 112 is provided on the protrusion 1141 .
[0087] It can be understood that in order to ensure the sealing between the machine door 120 and the machine body 110 and reduce vibration and noise when closing the door, a part of the window gasket 114 is arranged to extend out from the front surface of the front panel 113, so that the machine door 120 and the window gasket 114 are sealed against each other, and the sealing effect is better. The first conductor 112 is arranged on the protrusion 1141. When closing the door, the machine door 120 pushes back to squeeze the window gasket 114. The elasticity of the window gasket 114 is used to make the first conductor 112 protrude relative to the window gasket 114, further ensuring the contact between the first conductor 112 and the second conductor 121, avoiding the risk of false alarm.
[0088] In some embodiments, a portion of the first conductor 112 protrudes from the window gasket 114. In this way, when the machine door 120 closes the clothing inlet 111, the machine door 120 first contacts the first conductor 112 and applies a thrust to the first conductor 112, so that the first conductor 112 and the second conductor 121 maintain contact. At the same time, due to the elasticity of the window gasket 114, the first conductor 112 retreats and further squeezes the window gasket 114, so that the second conductor 121 contacts and contacts the first conductor 112 while the machine door 120 can contact and contact the window gasket 114, thereby ensuring the sealing reliability between the machine door 120 and the machine body 110.
[0089] In some embodiments, as Figure 4 and Figure 8 As shown, the window gasket 114 has a first lip 1142 and a second lip 1143 connected to the first lip 1142, the first lip 1142 is suitable for abutting against the door window 122 of the machine door 120, and the second lip 1143 is arranged opposite to the second conductor 121, wherein the first conductor 112 is arranged on the second lip 1143.
[0090] In this embodiment, a window gasket 114 is provided with a first lip 1142 and a second lip 1143. When the machine door 120 closes the clothing inlet 111, the first lip 1142 abuts against the door window 122 of the machine door 120, and the second lip 1143 abuts against the door frame of the machine door 120, forming a double sealing effect, thereby improving the sealing reliability between the machine door 120 and the machine body 110. At the same time, the first conductor 112 is provided on the second lip 1143. In this way, while realizing the detection of the closing status of the machine door 120 and whether the laundry is clamped, the sealing effect of the machine door 120 is guaranteed, water leakage (wind) is avoided, and the reliability of the product is improved.
[0091] For example, the first lip 1142 and the second lip 1143 together form a bifurcated structure with an opening at one end. The bifurcated structure has two branches. A portion or all of the first lip 1142 forms one branch of the bifurcated structure, and a portion or all of the second lip 1143 forms the other branch of the bifurcated structure. The opening of the bifurcated structure faces the door 120.
[0092] In this way, when the door 120 closes the clothing loading port 111, the first lip 1142 abuts against the door window 122 of the door 120, and the second lip 1143 abuts against the door frame of the door 120, wherein the door window 122 applies a force to the first lip 1142, so that the first lip 1142 and the door window 122 maintain abutment and sealing. At the same time, part of the force can be further applied to the second lip 1143 through the first lip 1142, causing the second lip 1143 to have a tendency to tilt toward the door 120, thereby pushing the door frame provided at the bottom of the door 120. The first conductor 112 of the second lip 1143 allows the first conductor 112 to better adhere to the second conductor 121, achieving a more reliable seal between the first lip 1142 and the door and window 122 and a more reliable contact between the first conductor 112 and the second conductor 121, and the rebound force generated by the second lip 1143 is in turn applied to the first lip 1142, which can further promote the abutment between the first lip 1142 and the door and window 122, and further improve the sealing reliability of the machine door 120 at the first lip 1142.
[0093] In some embodiments, the first conductor 112 is located on the front surface of the second lip 1143, and the rear surface of the second lip 1143 abuts against the front panel 113. When the machine door 120 closes the clothing inlet 111, the front panel 113 and the second conductor 121 clamp the second lip 1143 and the first conductor 112.
[0094] In this embodiment, when the machine door 120 closes the clothing inlet 111, the second lip 1143 abuts against the door frame of the machine door 120, wherein the door frame of the machine door 120 applies a force to the second lip 1143, so that the second lip 1143 tends to retreat. In order to avoid the unreliable contact between the first conductor 112 and the second conductor 121 due to the retreat of the second lip 1143, thereby causing a false alarm, the rear surface of the second lip 1143 is arranged to abut against the front plate 113, and the front plate 113 is used to support the second lip 1143, so that the front plate 113 and the second conductor 121 clamp the second lip 1143 and the first conductor 112, thereby further achieving more reliable contact between the first conductor 112 and the second conductor 121.
[0095] Furthermore, the second lip 1143 is bent from front to back to form a slot 1144, into which a portion of the front panel 113 extends. This further ensures the connection reliability between the front panel 113 and the second lip 1143, improves the installation reliability of the window gasket 114, and further strengthens the effect of the front panel 113 supporting the second lip 1143.
[0096] In some embodiments, the first conductor 112 and the window gasket 114 are separate components and are pluggably mated with each other, thereby achieving the replaceability of the first conductor 112 .
[0097] For example, the window gasket 114 has a groove, and a portion of the first conductive body 112 extends into the groove. Preferably, the first conductive body 112 and the window gasket 114 are tightly fitted.
[0098] For example, an adhesive connection may be provided between the first conductor 112 and the window gasket 114 .
[0099] In other embodiments, the portion of the window gasket 114 that contacts the second conductor 121 may be made of a conductive material, and the portion of the window gasket 114 made of a conductive material may be formed as the first conductor 112. For example, the first conductor 112 may be embedded in the window gasket 114 during the injection molding process.
[0100] In some embodiments, the machine door 120 includes a door window 122 , an outer door frame 123 and an inner door frame 124 , the inner door frame 124 is connected to the outer door frame 123 , and the inner door frame 124 and the outer door frame 123 clamp and lock the door window 122 , wherein the second conductor 121 is provided on the inner door frame 124 .
[0101] In this embodiment, the second conductor 121 is provided on the inner door frame 124. On the one hand, the clamping force between the door frame and the body 110 is utilized to improve the reliability of the contact between the first conductor 112 and the second conductor 121 and reduce the risk of error. On the other hand, the second conductor 121 is avoided from the door and window 122 to prevent the second conductor 121 from affecting the viewing effect of the door and window 122.
[0102] Preferably, a portion of the second conductor 121 protrudes from the inner door frame 124. Thus, when the door 120 closes the clothing inlet 111, the second conductor 121 first contacts the first conductor 112 and applies a thrust to the first conductor 112, maintaining contact between the first conductor 112 and the second conductor 121, further improving the reliability of the contact between the first conductor 112 and the second conductor 121.
[0103] In some embodiments, the second conductor 121 and the inner door frame 124 are separate components and the second conductor 121 and the inner door frame 124 are plug-fitted together to achieve the replaceability of the second conductor 121 .
[0104] For example, the inner door frame 124 has a groove, and a portion of the second conductor 121 extends into the groove. Preferably, the second conductor 121 and the inner door frame 124 are tightly fitted.
[0105] For example, an adhesive connection may be provided between the second conductor 121 and the inner door frame 124 .
[0106] In other embodiments, a portion of the inner door frame 124 is made of a conductive material, and the portion of the inner door frame 124 made of the conductive material is formed as the second conductor 121 .
[0107] For example, the second conductor 121 is arranged along the lower half of the inner door frame 124 , the outer surface of the second conductor 121 is exposed, and is embedded in the inner door frame 124 during the injection molding process.
[0108] In some embodiments, the laundry treating apparatus 100 further includes a detection device 140 and a control device 150 .
[0109] Specifically, the detection device 140 is arranged in the conductive circuit. The detection device 140 includes a detection module and a sending module. The detection module is suitable for detecting the electrical parameters of the conductive circuit and generating a detection signal according to the detection results. The sending module sends a detection signal. The control device 150 is connected to the detection device 140. The control device 150 is suitable for receiving the detection signal and controlling the operation of the clothing processing device 100 according to the detection signal.
[0110] In some embodiments, the detection device 140 is connected in series between the power supply device 130 and the first conductor 112 and / or the detection device 140 is connected in series between the power supply device 130 and the second conductor 121 .
[0111] In some embodiments, the detection device 140 and the control device 150 communicate wirelessly. This eliminates the need for wiring between the detection device 140 and the control device 150, further simplifying the structure of the product.
[0112] For example, the electrical parameters include any one or more of resistance, current, and voltage.
[0113] For example, the power supply device 130 is a driving board.
[0114] In some embodiments, the laundry processing apparatus 100 further includes an alarm device 160, which is connected to the control device 150. When the control device 150 fails to receive a detection signal or the received detection signal exceeds a preset threshold, the control device 150 controls the alarm device 160 to issue an alarm message. The alarm message issued by the alarm device 160 provides a timely reminder to the user, allowing the user to close the door 120 again after finishing the laundry. Preferably, the alarm message includes any one or more of an audio prompt, a text prompt, and a visual prompt.
[0115] It is worth noting that the preset threshold is the value of the detection signal of the conductive circuit when the door 120 is tightly closed and no laundry is clamped between the door 120 and the body 110. This embodiment does not make any specific limitation on the preset threshold.
[0116] Furthermore, “overflowing the preset threshold” may mean that the detection signal received by the control device 150 is lower than the preset threshold, or may mean that the detection signal received by the control device 150 is higher than the preset threshold.
[0117] The present invention further provides a control method for a clothes treating apparatus 100, which is applicable to the clothes treating apparatus 100 of any of the above embodiments, and comprises the following steps:
[0118] S101: Detecting electrical parameters of the conductive circuit of the laundry treatment device 100;
[0119] S102: Generate and send a detection signal according to the detection result;
[0120] S103: Determine whether the detection signal meets the preset operating conditions;
[0121] S104: If the detection signal meets the preset operating condition, the clothes treating apparatus 100 is controlled to pause the working program; otherwise, the clothes treating apparatus 100 is controlled to run the working program;
[0122] The preset operating condition is that the conductive circuit is not conducting or the detection signal of the conductive circuit exceeds a preset threshold.
[0123] The control method of the clothing processing device 100 provided by the present invention detects the electrical parameters of the conductive circuit. In this way, when the machine door 120 closes the clothing input port 111, the conductive circuit is connected, and when the machine door 120 opens the clothing input port 111, the conductive circuit is disconnected. The open and closed states of the machine door 120 are judged based on the on-off state of the conductive circuit. The judgment method is simpler and the judgment accuracy is higher.
[0124] At the same time, if the machine door 120 is not closed tightly or the laundry is clamped between the machine door 120 and the machine body 110, the electrical signal strength of the conductive circuit will be reduced, so that whether the machine door 120 is closed tightly and whether the machine door 120 is clamping the laundry can be judged according to the conductivity of the conductive circuit. The user does not need to look through the door window 122 to see whether the laundry is clamped by the machine door 120, which ensures that the laundry is put in place and avoids the situation where the working program is started when the laundry is clamped by the machine door 120 and the machine body 110, causing damage to the laundry, the machine body 110, and the machine door 120, thereby improving the user experience and the service life of the product.
[0125] In general, the present invention can accurately determine the conductivity of the conductive circuit. If the electrical signal of the conductive circuit is absent or the electrical signal strength is reduced, the clothing processing device 100 is controlled to suspend operation to avoid damage to the laundry, the machine door 120, and the machine body 110.
[0126] In a specific embodiment:
[0127] This embodiment provides a drum washing machine that can realize self-checking of the laundry loading status. The drum washing machine is composed of multiple systems such as a box module, a front panel 113 module, a drum module, a machine door 120, and a control module.
[0128] like Figure 1 As shown, the door module is installed on the front plate 113, and a rubber window gasket 114 is installed between the front plate 113 and the outer drum. The front plate 113, the inner drum and outer drum of the drum module and the window gasket 114 together constitute the clothing loading port 111 of the drum washing machine.
[0129] The machine door 120 includes an inner door frame 124, on which a second conductor 121 is installed. The second conductor 121 is arranged along the lower half of the inner door frame 124, and the outer surface of the second conductor 121 is exposed and visible. The second conductor 121 can be embedded in the inner door frame 124 during the injection molding process, or can be installed by snapping, gluing, etc. during the assembly process of the machine door 120.
[0130] The window gasket 114 is provided with a first conductor 112 on the area corresponding to the second conductor 121 installed on the inner door frame 124. Similarly, the first conductor 112 is also exposed and visible. The first conductor 112 can be embedded in the window gasket 114 during the injection molding process, or assembled later by gluing or other methods.
[0131] A signal transmission module is installed inside the front panel 113 , one end of which is electrically connected to the first conductor 112 on the window gasket 114 , and the other end of which is connected to the driving board of the washing machine through a wiring harness.
[0132] A signal transmission module is also provided on the inner side of the machine door 120 . Similarly, one end of the signal transmission module is electrically connected to the second conductor 121 on the inner door frame 124 , and the other end is connected to the driving board of the drum washing machine.
[0133] If the laundry is properly loaded, after the door 120 is closed, the second conductor 121 on the inner door frame 124 contacts the first conductor 112 on the window gasket 114, generating an electrical signal. This signal is transmitted via the signal transmission module inside the front panel 113 to the drum washing machine's control module. Once the control module determines that the laundry is loaded properly, it starts the washing process.
[0134] If the clothes are not properly placed and are outside the window mat 114, the exposed clothes will prevent the second conductor 121 on the inner door frame 124 from contacting the first conductor 112 on the window mat 114, resulting in no electrical signal or a reduced signal strength between the two. Similarly, this electrical signal is transmitted to the washing machine's control module via the signal transmission module. At this time, the control module recognizes that the clothes are not in the ideal state and will not start the washing process. Instead, it will remind the user to rearrange the clothes by flashing a light or sounding an alarm.
[0135] Preferably, in order to ensure sufficient contact between the second conductor 121 on the inner door frame 124 and the first conductor 112 on the window gasket 114 , both conductors protrude a certain distance from the product surface.
[0136] Preferably, after the door 120 is closed, the contact surfaces of the two conductors have a certain amount of interference, such as Figure 5 Since the window gasket 114 is made of rubber, it will deform and move backward when subjected to force, so the outer surfaces of the two conductors are in close contact after actual assembly.
[0137] The drum washing machine capable of self-checking the laundry loading status of the present invention has the following advantages:
[0138] By monitoring and providing feedback on the laundry loading status, damage to the laundry and the window gasket 114 caused by starting the washing program while the laundry is sandwiched between the door and the window gasket 114 is avoided. This improves the user experience and the life of the washing machine itself, reduces user complaints, and lowers the product's market defect rate.
[0139] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
