By accompanying drawing as can be known, structure of the present utility model comprises that casing is the stainless steel water bath cabinet (1) of laminated heat-preserving structure, console (12) is equipped with through the stainless steel work top in its top, described water bath (1) is equipped with the cartridge (4) with removable top cover and is positioned at the tubular type heating (3) of one side, and the catheter (8) that extends cartridge (4) bottom is connected with the peristaltic pump (7) that is installed on the console (12); Its design feature is, the jet flow stirring pump (2) that is suspended in about 1/2nd At The Heights with connecting rod (9) is housed in water bath (1), be contained in this water pump (2) with the impeller in the pump case of (referring to arrow E position among Fig. 3, and arrow E represents the direction of intaking) of inlet opening through rotating shaft (10) link to each other with the motor power axle that is contained on the console (12), described impeller has upper strata blade (14) and lower leave (13) (referring to Fig. 3), have horizontal tangential groove (42) corresponding to upper strata blade (14) height and position place on the pump case sidewall and it has perforate to be connected with the upper end of lower sparge pipe (11) corresponding to lower leave (13) height and position place, the lower end of lower sparge pipe (11) extends lower box and it has one to make the ejection current point to the elbow (referring to Fig. 2 and Fig. 3 arrow B place, this arrow B represents the water outlet direction) of cartridge (4) horizontal tangent direction.

Design principle of the present utility model and the course of work are, water bath (1) fills with clear water the soup of packing in the cartridge (4), the power supply of connecting tubular type heating (3) makes clear water in its heating water bath cabinet (1), and then cartridge (4) herb liquid produces heat exchange with clear water and is heated through barrel; Plugged makes jet flow stirring pump (2) work, then the water that pumps of upper strata blade (14) by in the groove (42) according to the tangential direction ejection, form the current that circulate around cartridge (4) (in referring to Fig. 2 and Fig. 3 shown in the arrow A) in cartridge mid-height position; And the water of lower sparge pipe (11) ejection forms the current that circulate around this cylindrical shell in cartridge (4) bottom, (referring among Fig. 2 and Fig. 3 shown in the arrow B), form thus current that circulate around cartridge (4) integral body, and liquid level upper, middle and lower layer each several part velocity of circulation reaches unanimity, make tube (4) herb liquid obtain homogeneous heating, make its temperature rise fast, the temperature field is even, thereby overcomes the deficiency of prior art. Peristaltic pump (7) is in order to realize perfusion.

As known from the above, the utility model is a kind of big capacity temp-constant medicinal liquid filling instrument, the cartridge of big volume is arranged and its heating soup temperature rise is fast, temperature evenly, filled up the blank of prior art.
