Summary of the invention
The present invention proposes a kind of heater for hemodialysis apparatus, in the water inlet of the top of water tank, solves the technical problem that there is the risk of leaking in existing heater.
The present invention adopts following technical scheme to realize: a kind of heater for hemodialysis apparatus, and it comprises: water tank; Be arranged on the heating rod of water tank inner bottom part; Be arranged on the water entering section in water tank, comprise vertically disposed the first conduit and the second conduit that is horizontally set on the water tank inner bottom part, the top end of the first conduit arranges water inlet tap, on the second conduit, sets out water nozzle, and the end of the second conduit is protruding upward arranges a support portion; Being arranged on Qie Yi support portion, support portion is the driving section that supporting-point rotates; In driving section, wherein an end is fixedly installed ball float, and another end downside in driving section protrudes the force section that faucet is exerted pressure is set downwards.
in a preferred embodiment, driving section comprises connecting rod and supporting plate; One end of connecting rod connects supporting plate, and another end of connecting rod arranges force section.
?in a preferred embodiment, the supporting plate dual-side all connects side plate is set, and the two ends of ball float are fixed by screws in respectively on the side plate of supporting plate dual-side.
?wherein, water entering section is L shaped.
?in a preferred embodiment, the bottom in water tank, be fixedly installed several water-line target sections arranged vertically at certain intervals.
Compared with prior art, the present invention has following beneficial effect:
the heater that the present invention proposes, arrange L shaped water entering section, and in the water inlet of the top of water tank and coordinate ball float automatically to control feed liquor, water tank, water entering section be all without thorough sealing, thereby can stop the risk of radiator leak; And it is more directly perceived, quick that the water-line target section be fixedly installed regulates liquid level.In addition, the present invention has advantages of simple in structure, safe and reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing heating chamber;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the enlarged diagram of regional A in Fig. 2.
The specific embodiment
Shown in Fig. 2 and Fig. 3, the heater that the present invention proposes comprises: water tank 1; Be arranged on the heating rod 2 of the bottom in water tank 1, the water for dialysis in 2 pairs of water tanks 1 of heating rod is heated; For L shaped water entering section 3, the second conduit 32 that it comprises vertically disposed the first conduit 31 and is horizontally set on water tank 1 inner bottom part, wherein, the end of the first conduit 31 arranges water inlet tap 311, the end of the second conduit 32 is protruding upward arranges a support portion 321, and also sets out water nozzle 322 on the second conduit 32; Take support portion 321 as supporting-point, be arranged on 321Shang driving section, support portion 4, this driving section 4 comprises connecting rod 41 and supporting plate 42, one end of connecting rod 41 connects supporting plate 42, the downward protrusion of the downside of another end of connecting rod 41 arranges 411，Gai force section, force section 411 and can exert pressure to faucet 322; Be fixedly installed on the ball float 5 on supporting plate 42, these supporting plate 42 dual-sides all arrange side plate 421, and two ends of ball float 5 are fixed on the side plate 421 of supporting plate 42 dual-sides by screw 422 respectively.In addition, the bottom in water tank 1, be fixedly connected with several water-line target sections 6 arranged vertically at certain intervals be set, and liquid level regulated more directly perceived, quick.
Operation principle of the present invention is as follows:
When 1, the liquid level in water tank 1 is relatively lower, now, self gravitation due to ball float 5, ball float 5 presses to supporting plate 42 on heating rod 2, drivening rod 41 be take support portion 321 as supporting, and the force section 411 that is arranged on connecting rod 41 ends upwarps, thereby can't be exerted pressure to faucet 322 in force section 411, make water for dialysis enter water entering section 3 from water inlet tap 311, be expelled to the inside of water tank 1 from faucet 322 through the first conduit 31, the second conduit 32 successively.
2, along with the liquid level in water tank 1 rises, ball float 5 starts floating under buoyancy, driving supporting plate 42 upwarps, the connecting rod 41 be connected with supporting plate 42 be take support portion 321 as support motion, is arranged on the force section 411 of connecting rod 41 ends and presses motion, until force section 411 is pressed on faucet 322 fully, faucet 322 is exerted pressure, faucet 322 is blocked fully, and water for dialysis cannot continue to discharge from faucet 322, thereby makes the liquid level of water tank 1 inside maintain certain altitude.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
