Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1 to 4, the nozzle base structure for effectively reducing the temperature provided by the embodiment of the utility model is used for connecting a nozzle 1 and a mixer barrel 2, and can effectively block heat transfer of the mixer barrel 2 to the nozzle 1, so that the service life of the nozzle 1 is prolonged; the nozzle base comprises a base plate 3, a base body 4 and a sealing gasket 5; the seat disc 3 is connected to the mixer cylinder 2 and comprises a first central channel 301, a hollow groove 302 and an edge connecting part 303; the seat body 4 is connected with the edge connecting part 303 of the seat tray 3, a plurality of grooves 401 are formed in the seat body 4, and the grooves 401 are communicated with the hollow grooves 302; the sealing gasket 5 is disposed between the base 4 and the nozzle 1.
