[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention of a POS printer that is easy to clean.

[0027] like Figures 1-5As shown, an easy-to-clean POS printer according to an embodiment of the present invention may include a printer body 100, a printhead 106 for printing is disposed within the printer body 100, and the printhead 106 is distributed in a linear array within the printer body 100; a cleaning device 200 for cleaning the printhead 106 is disposed within the printer body 100, the cleaning device 200 includes a cleaning component 220 disposed within the printer body 100 for cleaning the printhead 106, and a driving component 210 for driving the cleaning component 220 to move left and right within the printer body 100; thus, when it is necessary to clean the printhead 106, a micro motor 211 can drive a threaded rod 212 to clean it. The screw plate 222 rotates, and the screw rod 212 in the groove inside the printer body 100 moves to the left. At this time, the cleaning brush 223 in the storage frame 221 can clean several printheads 106 during the movement of the storage frame 221. The cleaned toner is collected and received through the storage frame 221. After cleaning several printheads 106, the left placement slot 108 can be opened through the cover plate 107, the bolt 226 can be loosened and removed from the baffle 224, and the baffle 224 can be removed from the storage frame 221 through the handle 225. The cleaned toner in the storage frame 221 can then be quickly and efficiently cleaned. Therefore, several printheads 106 can be cleaned quickly.

[0028] In one embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the left end of the printer body 100 is provided with a paper outlet 101 for discharging printed paper. Therefore, when the printer body 100 is working, the printed paper can be ejected along the paper outlet 101. A support plate 102 for placing the printed paper is fixedly installed on the left end of the printer body 100. Therefore, the support plate 102 can be used to support the paper coming out of the paper outlet 101.

[0029] Furthermore, a paper inlet 103 is provided at the left end of the printer body 100, and the paper inlet 103 is located directly below the paper outlet 101. A paper tray 104 for placing paper is movably connected inside the paper inlet 103, so the paper to be printed can be placed using the paper tray 104. A connecting plate 105 for connecting to the paper inlet 103 is movably connected inside the paper tray 104, so the paper tray 104 can be lowered from the paper inlet 103 using the connecting plate 105, and paper can be placed into the paper tray 104, so that the printer body 100 can print the paper in the paper tray 104.

[0030] Furthermore, the printer body 100 has two placement slots 108 for placing the cleaning component 220. The two placement slots 108 are symmetrically distributed in the printer body 100. The left end of the printer body 100 is movably connected to a cover plate 107 for opening the left placement slot 108. The cover plate 107 is connected to the left placement slot 108 by a hinge. Therefore, when it is necessary to clean the toner on the cleaning device 200, the left placement slot 108 can be opened through the cover plate 107, so that the toner in the cleaning device 200 can be easily collected and cleaned.

[0031] In one embodiment of this utility model, as shown in the figure, the drive assembly 210 includes a threaded rod 212 disposed within the printer body 100 for driving the cleaning assembly 220 to move left and right. The left and right ends of the threaded rod 212 are connected to the printer body 100 via bearings, thus facilitating the rotation of the threaded rod 212. A micro motor 211 for driving the rotation of the threaded rod 212 is fixedly installed at the right end of the threaded rod 212, wherein the micro motor 211 is connected to the rod end of the threaded rod 212 via a coupling. Therefore, the rotation of the threaded rod 212 can be easily driven when the micro motor 211 is working.

[0032] Furthermore, the cleaning assembly 220 includes a threaded sleeve 222 fitted onto the threaded rod 212 for moving left and right along the threaded rod 212. The threaded sleeve 222 can move within a recess in the printer body 100. Therefore, when the threaded sleeve 222 moves left and right along the threaded rod 212, the recess in the printer body 100 can be used to limit the threaded sleeve 222 to move left and right along the threaded rod 212 without rotation. A storage frame 221 is fixedly installed at the front end of the threaded sleeve 222, and the cross-section of the storage frame 221 is concave. Therefore, the storage frame 221 can be used to prevent toner and dust leakage. A cleaning brush 223 for cleaning the print head 106 is fixedly installed at the bottom of the cavity of the storage frame 221.

[0033] Furthermore, a baffle 224 for opening and closing the storage frame 221 is provided at the left end of the storage frame 221. A handle 225 for driving the baffle 224 to move left and right is fixedly installed at the front end of the baffle 224. A bolt 226 for locking the baffle 224 is provided on the plate body of the baffle 224. Therefore, the bolt 226 can be loosened and removed from the baffle 224, and the baffle 224 can be removed from the storage frame 221 by using the handle 225, so that the cleaned toner in the storage frame 221 can be quickly and centrally cleaned.

[0034] In summary, this utility model provides a POS printer that is easy to clean. When the printhead 106 needs to be cleaned, the micro motor 211 drives the threaded rod 212 to rotate, and the threaded sleeve 222 can move to the left along the threaded rod 212 in the groove inside the printer body 100. At this time, the cleaning brush 223 in the storage frame 221 can clean several printheads 106 during the movement of the storage frame 221, and the cleaned toner will be collected and received through the storage frame 221. After cleaning several printheads 106, the left placement slot 108 can be opened through the cover plate 107, the bolt 226 can be loosened and removed from the baffle 224, and the baffle 224 can be removed from the storage frame 221 through the handle 225. This allows for quick and concentrated cleaning of the toner in the storage frame 221. Therefore, several printheads 106 can be cleaned quickly, thereby solving problems such as printhead clogging and blurry printing caused by toner residue and dust accumulation.
