Description

Liquid type washing agent automatic throw-in equipment

Technical field

The utility model relates to a kind of liquid type washing agent automatic throw-in equipment, especially a kind of liquid type washing agent automatic throw-in equipment that improves structure.

Background technology

In the prior art about the liquid type washing agent automatic throw-in equipment of gear pump; Can't realize the input of accurate quantification; The liquid type washing agent, like liquid detergent, softener, disinfectant etc., its viscosity has nothing in common with each other because of kind and brand; The changes in flow rate scope that general gear pump or other pumps are influenced in its certain hour by viscosity all is very big, has no idea to realize accurately to control input amount.

So, need a kind of new technical scheme to address the above problem.

The utility model content

The purpose of the utility model is the deficiency that exists to prior art, provides a kind of and realizes the accurate liquid type washing agent automatic throw-in equipment of throwing in of liquid type washing agent.

For realizing above-mentioned purpose, the utility model liquid type washing agent automatic throw-in equipment can adopt following technical scheme:

A kind of liquid type washing agent automatic throw-in equipment; Comprise washing agent case, the pump that links to each other with the washing agent case, the driving mechanism that links to each other with pump; Said driving mechanism is connected with the hall sensing device; Said hall sensing device comprises hall sensor and is connected the spinner member on the driving mechanism; Said spinner member rotates along with the rotation of driving mechanism, and this liquid type washing agent automatic throw-in equipment also has electronic controller, and this electronic controller is connected with hall sensor and driving mechanism.

Compare with background technology; The electronic controller of the utility model liquid type washing agent automatic throw-in equipment through the hall sensing device being set and connecting hall sensing device and driving mechanism; Make the hall sensing device induce the revolution of driving mechanism and feed back to electronic controller; Electronic controller judges whether the revolution of needs adjustment driving element according to the revolution signal of this feedback, and the revolution that makes driving element is based on proper level, thereby makes the accurately quantitative input of liquid type washing agent.

Fig. 1 is the structural representation of the utility model liquid type washing agent automatic throw-in equipment.

Fig. 2 is the interactively figure of each several part in the utility model liquid type washing agent automatic throw-in equipment.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment; Further illustrate the utility model; Should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.

See also Fig. 1 and shown in Figure 2; The utility model discloses a kind of liquid type washing agent automatic throw-in equipment 100, and this liquid type washing agent automatic throw-in equipment 100 comprises washing agent case 20, the pump 30 that links to each other with washing agent case 20, the driving mechanism 40, the hall sensing device 50 that is connected with driving mechanism 40 and the electronic controller 60 that link to each other with pump 30.Outputting power is provided 40 pairs of pumps 30 of said driving mechanism so that pump 30 work.Said hall sensing device 50 comprises hall sensor 51 and is connected the spinner member 52 on the driving mechanism 40.Said driving mechanism 40 comprises motor (not shown), and selectablely has a reducing gear (not shown), and said spinner member 52 is connected with the rotating shaft (not shown) of motor, makes spinner member 52 rotate along with the rotation of driving mechanism 40.Said electronic controller 60 is connected with hall sensor 51 and driving mechanism 40.In this embodiment; Said spinner member 52 is a runner; And at least one magnet (not shown) is installed on this runner, and hall sensor 51 detects the magnet of processes and calculates the revolution of motor, and the revolution signal of feedback motor is to controlling driving mechanism 40.Whether electronic controller 60 can move according to the feedback signal control driving mechanism 40 of hall sensor 51, whether pump 30 outputting powers is made pump 30 work with control driving mechanism 40.The utility model is through the revolution of hall sensor 51 feedback motors; Can carry the flow of liquid type washing agent according to the revolution control pump 30 of motor; Thereby make the commentaries on classics of 60 pairs of driving mechanisms 40 of electronic controller stop controlling, make pump 30 carry the flow of liquid type washing agent accurate more and stable.

Pump 30 in the utility model is the positive displacement gear pump.Positive displacement pump is a type of pump; It is the cyclically-varying that relies on the seal operation spatial volume that contains liquid; Energy cycle property pass to liquid, the pressure of liquid is increased to liquid is discharged by force, can be divided into reciprocating pump and drum pump again according to the forms of motion of workpiece.And the positive displacement gear pump belongs to a kind of of drum pump, relies between gear pump body and meshing gear formed swept volume to change and moves and carry liquid or make the liquid supercharging.With one group of working gear is example, and a pair of pitch wheel and gear cavity separate suction chamber and discharge side; When gear rotated, the suction chamber side gear teeth between cog volume of disengagement place each other increased gradually, and pressure reduces, and liquid gets between cog under the effect of pressure reduction; Along with the rotation of gear, the liquid of between cog is brought into discharge side one by one, and at this moment the between cog volume of discharge side side wheel tooth engagement place dwindles gradually, and liquid is discharged.The characteristics of positive displacement gear pump are that the fluid flow of being carried is stable when rotating a circle, and are irrelevant with the velocity of rotation of pump, so can under the control of electronic controller 60, carry the liquid type washing agent more accurately.And since hall sensor 51 feedback be the motor revolution; So can determine the flow that the positive displacement gear pump is carried the liquid type washing agent accurately according to the motor revolution; Make the judgement of 60 pairs of flows of electronic controller more accurate, and system is only needed to confirm the scope of a suitable revolution, and detected revolution signal is rotated the number of turns with preset driving mechanism carry out; The commentaries on classics of control driving mechanism stops, and makes that the computational process of system is easier.
