Problems solved by technology
[0002] In traditional inkjet printers, the electrical connection between the nozzle and the carriage circuit board is realized through the reed connector and the contact belt. This connection structure is easy to cause some contacts to be damaged due to the large number of contacts. Poor contact is also prone to misalignment between the contacts and the reed connector, causing the printer to be unable to perform printing work; in addition, especially when the nozzle or the word car circuit board is damaged and needs to be replaced, if you are not careful during the operation If the ink is stained on the contacts, once the printer is powered on, the circuit board connected to the contacts and the main board inside the printer will be burnt out, which brings a great deal of trouble to the printer in the process of disassembling and replacing accessories. risk; and because of the high process requirements of the reed connector and the contact strip structure, the cost of printer production is increased

Embodiment Construction
[0015] refer to Figure 1~Figure 4 , a printer nozzle structure of the present invention, it comprises nozzle 1, and the bottom end of nozzle 1 is provided with nozzle hole, is connected with the data flat line 2 that is used for being electrically connected with character car circuit board 4 on the described nozzle hole, and data flat wire The other end of 2 is plugged into the wiring slot 41 of the character car circuit board 4, and the character car circuit board 4 is bonded to the nozzle 1 through screw connection or glue coating. When the printer is printing, the printer main board inside the printer Send the printing information to the character car circuit board 4, and the character car circuit board 4 controls the opening and closing of the nozzle holes on the nozzle 1 through the data cable 2 according to the requirements of the printing information, and finally forms the characters or patterns to be printed. This abandons the structure in the traditional technolo...

The invention discloses a printer nozzle structure, which comprises a nozzle, wherein the bottom end of the nozzle is provided with an orifice; and a data flat cable which is used for being electrically connected with a transport circuit board is connected to the orifice. The data flat cable is arranged on the orifice of the nozzle, so that the data flat cable is electrically connected with the transport circuit board, an electric connection structure through a reed communicator and a contact strip in the prior art is abandoned, and a phenomenon that the transport circuit board and a printer motherboard are burnt because ink stains the contact when a user replaces the nozzle or the transport circuit board is avoided; meanwhile, because the data flat cable is manufactured by the conventional process, the process cost is low, and the production and use cost of the whole printer is reduced. The printer nozzle structure is simple and reasonable in structure and low in process cost, and the transport circuit board and the printer can be effectively prevented from being burnt.
