Improvement-based ink droplet charging small character nozzle device

Abstract

The invention provides an improvement-based ink droplet charging small character nozzle device. The device comprises a nozzle body and a constant temperature sleeve; the constant temperature sleeve fixedly sleeves the nozzle body; an adjusting sleeve fixedly sleeves the middle part of the constant temperature sleeve; an atomizing sleeve fixedly sleeves the bottom of the constant temperature sleeve; and an annular cold water cavity, an annular hot water cavity and an annular equipment cavity are formed in the adjusting sleeve. The improvement-based ink droplet charging small character nozzle device is reasonable in design, and the annular hot water cavity and the annular cold water cavity in the adjusting sleeve can continuously convey hot water or cold water to a constant temperature watercavity in the constant temperature sleeve; and when the external environment temperature is not within a working temperature range of the nozzle body, the temperature can be adjusted immediately, sothat the nozzle body can be always within the working temperature range, and the nozzle is prevented from being blocked due to adverse effects of excessively high or excessively low external temperature on ink.

Description

technical field [0001] The invention belongs to the technical field of printers, in particular to an improved ink drop charging small character spray head device. Background technique [0002] The stability of the ink determines the use of the nozzle of the inkjet printer, and the stability of the ink is determined by factors such as the viscosity, surface tension, volatility and fluidity of the ink. Therefore, a sharp change in temperature and humidity will affect the stability of the ink. Therefore, when the inkjet printer leaves the factory, each inkjet printer manufacturer will have a specific temperature and humidity limit for the use environment of the inkjet equipment, which generally requires 20°C-28°C. If the nozzle is not cleaned at the time, the ink may dry up and adhere to the nozzle if the machine is not used for a long time, or the dust in the working environment may cause more dust to adhere to the nozzle, and it is easy to clean or difficult to clean. Some s...

[0002] The stability of the ink determines the use of the nozzle of the inkjet printer, and the stability of the ink is determined by factors such as the viscosity, surface tension, volatility and fluidity of the ink. Therefore, a sharp change in temperature and humidity will affect the stability of the ink. Therefore, when the inkjet printer leaves the factory, each inkjet printer manufacturer will have a specific temperature and humidity limit for the use environment of the inkjet equipment, which generally requires 20°C-28°C. If the nozzle is not cleaned at the time, the ink may dry up and adhere to the nozzle if the machine is not used for a long time, or the dust in the working environment may cause more dust to adhere to the nozzle, and it is easy to clean or difficult to clean. Some small-character nozzles cannot adjust the ambient temperature of the small-character nozzles, which is not conducive to the normal operation of the small-character nozzles, and has low adaptability to the environment. Moreover, the existing small-character nozzles cannot clean the nozzles. Softening the nozzle is not conducive to the cleaning of small character nozzles. Therefore, the present invention proposes an improved ink droplet charging small character nozzle device
