[0002] With the continuous development of technology, printer technology, especially rotary printers, is also constantly progressing.

[0003] Taking a rotary printer as an example, the printers in the prior art mainly consist of a motor and an ink cartridge unit. The output end of the motor is connected to the ink cartridge unit and can drive it to rotate. The ink cartridge unit can print on a printing medium in a rotating state, such as printing an official seal. Among them, the ink cartridge unit includes an ink cartridge unit body and a printing nozzle. The ink cartridge unit body has an ink storage chamber and a drain hole that can communicate with the ink storage chamber. The printing nozzle is arranged at the bottom of the ink cartridge unit body, and the printing nozzle has an ink jet hole that can communicate with the drain hole.

[0004] However, the moisture in the ink of the printing nozzle is likely to volatilize. If people do not use the printer for a period of time, after the moisture in the ink volatilizes, the ink will become viscous or even dry up, which will cause the ink jet hole to be blocked. Once the ink jet hole is blocked, the ink cannot be ejected normally, directly affecting the printing effect, resulting in problems such as blurred printing, broken lines or completely unable to print, and at the same time reducing the printing efficiency.

[0059] Figures 1 to 21 The base 1 provided by the present utility model is shown. As can be seen from the figure, the present utility model provides a base 1 applied to a printer 2. The printer 2 has a printing end 220, and the printing end 220 has an inkjet area 221. There is at least one inkjet hole on the printing end 220 and located in the inkjet area 221. The base 1 includes a support housing 11 and a cleaning mechanism 12. The cleaning mechanism 12 is arranged on the support housing 11 and can clean the blockage at the inkjet hole in the state where the printer 2 is connected to the support housing 11.

[0060] In specific implementation, the base 1 and the printing system of the present utility model mainly aim at the technical problem that after the printer 2 has not been used for a long time, the ink becomes viscous or even dries up due to the volatilization of water, resulting in the blockage of the inkjet holes, and provides an innovative solution. This base 1 is specially designed with a support housing 11 and a cleaning mechanism 12. When the printer 2 is connected to the support housing 11 of the base 1, the cleaning mechanism 12 can effectively remove the blockage in the inkjet holes. Through this design, the base 1 can not only support the printer 2, but also perform the maintenance and cleaning of the inkjet holes when the printer 2 is connected thereto, avoiding printing quality problems caused by blocked nozzles, such as blurred printing, broken lines or inability to print, etc., thus significantly improving the printing efficiency and printing quality. The application of this technology makes users more worry-free when using the printer 2, reduces the frequency and cost of maintaining the printer 2, and at the same time extends the service life of the printer 2, ensuring the continuity and stability of printing work.

[0061] In this embodiment, the printer 2 can be an existing rotary printer 2, and the rotary printer 2 can be columnar. The rotary printer 2 can be analogous to a floor washer, and the base 1 can be analogous to the base station of the floor washer. When the floor washer is not in use, it can be placed on the base station. Similarly, when the rotary printer 2 is not in use, the rotary printer 2 can be placed on the base 1. The printing end 220 can be located at the lower end of the printer 2. The inkjet area 221 can be rectangular, and reference can be made to Figure 4 the area enclosed by the center dash line. The number of inkjet holes can exceed 300. The support seat body can be in the shape of a regular frustum of a cone. The printer 2 can be placed vertically at the small-diameter end of the support seat body and be snap-connected.

[0062] According to an embodiment of the present utility model, the cleaning mechanism 12 includes a suction structure 121. The suction structure 121 is arranged on the support housing 11. The suction structure 121 can generate negative pressure. The suction structure 121 has a suction port 12041. In the state where the printer 2 is connected to the support housing 11, the suction port 12041 can suck the blockage at the inkjet holes.

[0063] In specific implementation, the suction structure 121 is ingeniously installed on the support housing 11 and has a suction port 12041 dedicated to sucking the blockage in the inkjet holes. When the printer 2 is placed on the base 1 and connected to the support housing 11, the suction structure 121 starts to work. Through the action of negative pressure, the suction port 12041 can efficiently suck away the blockage in the inkjet holes, just like using a vacuum cleaner, but the present utility model is aimed at the inkjet holes of the printer 2. This design not only improves the cleaning efficiency, but also ensures the accuracy of the cleaning process, avoiding the damage or omission that may be caused by manual cleaning.

[0064] As Figures 3 to 6As shown, according to an embodiment of the present utility model, the support housing 11 has a cavity 1111 and an insertion hole 1121; the cavity 1111 is located inside the support housing 11; the insertion hole 1121 is located on the surface of the support housing 11, and the insertion hole 1121 can communicate with the cavity 1111; the inkjet area 221 is located inside the insertion hole 1121 when the printer 2 is connected to the support housing 11; the suction structure 121 is arranged inside the cavity 1111; the suction port 12041 faces the inkjet area 221 when the printer 2 is connected to the support housing 11.

[0065] In specific implementation, the cavity 1111 is located inside the support housing 11, while the insertion hole 1121 is on the surface of the support housing 11 and can communicate with the cavity 1111. This design enables the inkjet area 221 of the printing end 220 to be exactly located inside the insertion hole 1121 when the printer 2 is connected to the support housing 11, ensuring that the suction structure 121 can effectively clean the inkjet holes on the inkjet area 221. The suction structure 121 is arranged inside the cavity 1111, and its suction port 12041 directly faces the inkjet area 221 when the printer 2 is connected to the support housing 11, enabling the negative pressure suction function to directly act on the inkjet holes and effectively suck out the blockages. This design not only improves the accuracy and efficiency of cleaning but also makes the cleaning process more automated and simple through the built-in spatial layout. The user of the printer 2 only needs to connect the printer 2 to the base 1, such as placing it thereon, to perform the cleaning work of the inkjet holes, greatly reducing the complexity and time cost of manual maintenance, and at the same time reducing the risk of damage to the printer 2 caused by improper maintenance, further enhancing the usability and stability of the printer 2.

[0066] In this embodiment, the insertion hole 1121 can be located at the top of the support housing 11, and the insertion hole 1121 can be rectangular.

[0067] As Figure 3 and Figure 4 shown, according to an embodiment of the present utility model, the printer 2 includes an ink cartridge unit 20, and the ink cartridge unit 20 includes an ink cartridge unit main body 21 and a print head 22; the ink cartridge unit main body 21 has an ink supply end 211 for supplying ink to the print head 22; the print head 22 is arranged on the ink supply end 211; the print head 22 has the printing end 220; the suction port 12041 faces the inkjet area 221 when the ink supply end 211 is connected to the support housing 11.

[0068] During specific implementation, the main body 21 of the ink cartridge unit is designed with an ink supply end 211, which is responsible for supplying ink to the print head 22. The print head 22 is installed on the ink supply end 211 and has a printing end 220, that is, the location where the inkjet area 221 is located. When the ink supply end 211 is connected to the support housing 11 of the base 1, the suction port 12041 of the suction structure 121 arranged in the support housing 11 faces the inkjet area 221. By using the negative pressure suction function, it directly aims at the inkjet holes for cleaning, effectively sucking out the blockages in the holes.

[0069] In this embodiment, the main body 21 of the ink cartridge unit has an ink storage chamber and an ink outlet hole; the ink storage chamber is located inside the main body 21 of the ink cartridge unit; the ink outlet hole is located at the bottom of the main body 21 of the ink cartridge unit.

[0070] As Figure 7 、 Figure 8 and 18 shown, according to an embodiment of the present invention, the suction structure 121 includes a suction component 1211 and a collection component 1212; the suction component 1211 has the suction port 12041 and a discharge port; the collection component 1212 has a receiving chamber and a through hole 12121; the receiving chamber can accommodate the blocked hole matter; the discharge port communicates with the receiving chamber through the through hole 12121.

[0071] During specific implementation, the suction component 1211 is the part that directly interacts with the inkjet holes. It includes a suction port 12041, which is the starting point of the negative pressure suction process, and a discharge port for transporting the sucked blocked hole matter from the suction port 12041 to the collection component 1212. The collection component 1212 is responsible for receiving and storing these sucked blocked hole matters. It includes a receiving chamber for storing the cleaned impurities and a through hole 12121 connecting the discharge port and the receiving chamber to ensure that the blocked hole matter can be smoothly transported from the inkjet holes to the receiving chamber. This design not only improves the cleaning efficiency but also effectively collects and stores the cleaned impurities.

[0072] As Figure 7 shown, according to an embodiment of the present invention, the suction component 1211 includes a suction pump 12111 and a straw component 12112; the suction pump 12111 has a pump inlet and the discharge port; the straw component 12112 has the suction port 12041, a channel, and a discharge outlet 12031; the suction port 12041 is sequentially communicated with the pump inlet through the channel and the discharge outlet 12031.

[0073] During specific implementation, the suction pump 12111 is the core component that generates negative pressure and drives the entire suction process. It has a pump inlet and a discharge port, and the discharge port is connected to the discharge port of the suction component 1211 to form a discharge channel for the blockage. The suction pipe component 12112 includes a suction port 12041, a channel, and a discharge port 12031. The suction port 12041 directly faces the inkjet holes of the printer 2, is connected to the discharge port 12031 through the channel, and finally communicates with the pump inlet of the suction pump 12111, ensuring that the blockage can be effectively sucked out from the inkjet holes and transported to the collection component 1212. The collection component 1212 is equipped with a receiving cavity and a through hole 12121. The receiving cavity is used to store the blocked hole materials sucked out, and the through hole 12121 is responsible for introducing the blocked hole materials discharged by the suction pump 12111 into the receiving cavity.

[0074] As Figures 7 to 9 shown, according to an embodiment of the present invention, there are multiple inkjet holes, and the multiple inkjet holes are arranged at intervals on the inkjet area 221; the cleaning mechanism 12 further includes a driving structure 122, the driving structure 122 is arranged in the cavity 1111, the driving structure 122 is connected to the suction pipe component 12112, and can drive the suction pipe component 12112 to move relative to the printing end 220, so that the suction port 12041 can suck the blockage in each of the inkjet holes.

[0075] During specific implementation, in order to effectively clean these inkjet holes, the cleaning mechanism 12 of the base 1 not only includes the aforementioned suction component 1211 and collection component 1212, but also adds a driving structure 122. This driving structure 122 is cleverly arranged in the cavity 1111 of the support shell 11 and is connected to the suction pipe component 12112. Through the action of the driving structure 122, the suction pipe component 12112 can move relative to the printing end 220, so that the suction port 12041 can sequentially align with and suck the blockage in each inkjet hole. Such a design not only improves the coverage and efficiency of the cleaning work, but also helps to maintain the consistency of the printing quality by ensuring that each inkjet hole receives the same attention. By integrating the driving structure 122, the base 1 can automatically provide precise cleaning services for each inkjet hole of the print head 22, reducing manual intervention and reducing printing problems caused by inkjet hole blockage, thus significantly improving the reliability of the printing operation and the overall performance of the printer 2.

[0076] As Figure 9 shown, in this embodiment, the driving structure 122 can perform reciprocating linear motion along the first direction F; the first direction F is parallel to the end face of the printing end 220.

The linear motion assembly 1223 has a plurality of transmission teeth; the plurality of transmission teeth are arranged in sequence along the first direction F, and the transmission teeth are engaged with the gear 1222.

[0078] During specific implementation, the motor 1221 serves as a power source.

[0085] In this embodiment, the bottom of the nozzle 12104 can be snap-fitted at the mounting hole 12321. The delivery pipe 12103 can be a silicone hose.

[0086] As Figures 5 to 7 shown, according to an embodiment of the present invention, the support housing 11 includes a receiving housing 111 and a top cover 112; the receiving housing 111 has the cavity 1111 and a sliding hole 1112 that can communicate with the cavity 1111; the sliding hole 1112 is located at the top of the receiving housing 111 and is arranged along the first direction F; the top cover 112 is provided on the top of the receiving housing 111, and the top cover 112 has the insertion hole 1121, and the insertion hole 1121 communicates with the cavity 1111 through the sliding hole 1112; the connecting plate 12232 is located in the sliding hole 1112, and the edge of the connecting plate 12232 is slidably connected to the hole wall of the sliding hole 1112; the inkjet area 221 is located at the insertion hole 1121 in a state where the ink supply end 211 is connected to the top cover 112.

[0087] During specific implementation, a cavity 1111 is designed inside the accommodation shell 111, which is the space for placing and protecting the cleaning mechanism 12.

The top cover 112 is installed on the top of the accommodation shell 111 and is provided with a protruding hole 1121. The protruding hole 1121 communicates with the cavity 1111 through the sliding hole 1112, so that when the printer 2 is placed on the base 1, the inkjet area 221 of the print head 22 can be accurately located at the protruding hole 1121, ensuring that the inkjet area 221 can be effectively accessed by the cleaning mechanism 12. The connecting plate 12232 is arranged in the sliding hole 1112, and its edge can slide along the hole wall of the sliding hole 1112. Such a design allows the connecting plate 12232 and the connected straw assembly 12112 to smoothly move to directly above the inkjet area 221 when the print head 22 is connected to the top cover 112 of the support housing 11, ensuring the stable operation of the cleaning mechanism 12.

[0090] In another feasible embodiment, the hole wall of the sliding hole 1112 has a limiting groove 12322 arranged along the first direction F, and the edge of the connecting plate 12232 has a limiting strip 11120 matching the shape of the limiting groove 12322. The limiting strip 11120 is located in the limiting groove 12322 and can be slidably connected to the groove wall of the limiting groove 12322.

[0091] According to an embodiment of the present invention, the driving structure 122 further includes a controller, which is connected to the motor 1221 and can control the rotation of the motor 1221.

[0092] As Figures 4 to 7As shown, according to an embodiment of the present invention, the inkjet area 221 has a first end 2211 and a second end 2212 that are oppositely arranged along the first direction F; the driving structure 122 further includes a first optoelectronic switch 1224 and a second optoelectronic switch 1225; the controller is connected to the first optoelectronic switch 1224 and the second optoelectronic switch 1225; the first optoelectronic switch 1224 and the second optoelectronic switch 1225 are arranged in the cavity 1111 and can detect the position of the linear motion assembly 1223; wherein, the linear motion assembly 1223 is located between the first optoelectronic switch 1224 and the second optoelectronic switch 1225 and can move between the first optoelectronic switch 1224 and the second optoelectronic switch 1225, so that the nozzle 12104 moves between the first end 2211 and the second end 2212.

[0093] In specific implementation, the inkjet area 221 is defined as having two opposite end points, namely the first end 2211 and the second end 2212, which are arranged along the first direction F in which the cleaning mechanism 12 moves. To ensure that the nozzle 12104 can accurately move between these two end points of the inkjet area 221, a first optoelectronic switch 1224 and a second optoelectronic switch 1225 are added to the driving structure 122. These two optoelectronic switches are installed in the cavity 1111 of the support housing 11 and are connected to the controller. Their function is to detect the current position of the linear motion assembly 1223. When the linear motion assembly 1223, that is, the part that drives the straw assembly 12112 to move, is located between the two optoelectronic switches, its position will be accurately detected, so as to ensure that the nozzle 12104 can accurately move between the first end 2211 and the second end 2212 of the inkjet area 221 to perform the cleaning task.

Through this intelligent control, the maintenance of the printer 2 becomes more automated and simple, significantly improving the printing quality and the service life of the printer 2.

[0094] As Figures 16 to 18 As shown, according to an embodiment of the present invention, it further includes a humidifying mechanism 13. The humidifying mechanism 13 is arranged in the cavity 1111. The humidifying mechanism 13 can release moisture in the state where the ink supply end 211 is connected to the support housing 11 to increase the humidity of the air at the insertion hole 1121.

[0095] During specific implementation, the humidifying mechanism 13 is placed inside the cavity 1111 of the support housing 11. When the ink supply end 211 of the printer 2 is connected to the support housing 11, the humidifying mechanism 13 starts to work, releasing water molecules to increase the humidity of the air inside the insertion hole 1121. This design is crucial for maintaining the inkjet area 221 of the print head 22 because it can prevent the ink from evaporating excessively due to long-term exposure to a dry environment, resulting in the drying up or clogging of the inkjet holes. By maintaining an appropriate humidity level. In addition, this also reduces the frequent cleaning or replacement required due to nozzle clogging, extends the service life of the print head 22, and reduces the maintenance cost of the printer 2. In short, the addition of the humidifying mechanism 13 provides a humid working environment for the printer 2, thereby improving the printing efficiency and reliability.

[0096] In a feasible implementation manner, the humidifying mechanism 13 includes a moisture-retaining packet.

[0097] During specific implementation, this moisture-retaining packet is part of the humidifying mechanism 13, and its main function is to provide continuous moisture retention for the inkjet area 221 of the print head 22 when the printer 2 is not working. The moisture-retaining packet is usually made of materials with high water absorption, such as gels or superabsorbent polymers, which can lock in moisture and release it slowly to maintain the humidity of the inkjet area 221. By integrating the moisture-retaining packet inside the cavity 1111 of the base 1, the risk of the inkjet holes drying up due to long-term exposure to air can be effectively reduced, preventing the ink from becoming viscous or clogged, and ensuring that the printer 2 can quickly return to a good printing state after being idle for a long time. This design improves the maintenance efficiency of the printer 2, reduces printing quality problems caused by environmental factors, and also reduces the need for users to perform frequent maintenance on the printer 2, extends the service life of the printer 2, and enhances the user experience. In addition, the structure of the moisture-retaining packet is simple.

[0098] In this implementation manner, it can be an existing cigar moisture-retaining packet.

The humidifying cover 131 has a mist outlet 1312 that can communicate with the liquid storage cavity 1311; the mist outlet 1312 exposes the insertion hole 1121; the atomization sheet 132 is arranged in the liquid storage cavity 1311 and can emit mist through the mist outlet 1312.

[0100] During specific implementation, the humidifying mechanism 13 consists of two parts: a humidifying cover 131 and an atomizing sheet 132. Among them, the humidifying cover 131 is installed at the bottom of the cavity 1111, and together with the bottom of the cavity 1111, it encloses a liquid storage cavity 1311 for storing the moisture required for humidification. The humidifying cover 131 is designed with a mist outlet 1312, and this mist outlet 1312 penetrates into the insertion hole 1121, enabling the mist generated during humidification to directly enter the inkjet area 221 of the printer 2. The atomizing sheet 132 is placed in the liquid storage cavity 1311 and is responsible for converting the moisture in the liquid storage cavity 1311 into fine mist and releasing it to the outside through the mist outlet 1312.

One end of it is immersed in the bottom of the liquid storage cavity 1311, directly contacting the stored moisture, while the other end extends to the top of the liquid storage cavity 1311 and contacts the atomizing sheet 132 located at the top. Such a layout allows the porous liquid guiding structure 133 to fully absorb the moisture in the liquid storage cavity 1311 and continuously supply liquid to the atomizing sheet 132 for it to be converted into mist.

[0104] According to an embodiment of the present invention, the porous liquid guiding structure 133 is a structural member made of cotton or sponge.

[0107] In specific implementation, the scraping structure 123 is prominently arranged outside the suction nozzle 12104. When the ink supply end 211 of the printer 2 is connected to the support housing 11, the scraping structure 123 can directly contact the inkjet area 221 of the print head 22. Driven by the drive structure 122, the scraping structure 123 moves along the inkjet area 221, and the clogging matter around the inkjet holes is removed by physical scraping. This mechanical cleaning method can be a powerful supplement to the suction structure 121, especially suitable for stubborn blockages that are difficult to be sucked by negative pressure. Through the scraping action, the dried ink or impurities at the edge of the inkjet holes can be effectively removed, thus ensuring the smoothness of the inkjet holes. This design significantly improves the cleaning ability of the cleaning mechanism 12, enables the printer 2 to still maintain the best printing state after long-term use, avoids printing quality problems caused by nozzle blockage, reduces the workload of the user in maintaining the printer 2, and improves the operating efficiency and service life of the printer 2.
