The utility model proposes a kind of water purifier.

In this utility model embodiment, as shown in figure 4, the water purifier includes multiple filter elements 100, connects multiple filters The water route 200 of core 100, and connect with the water route 200 and to be at least described in one filter element 100 supercharging diaphragm booster pump 300；

Referring to figs. 1 to Fig. 3, the diaphragm booster pump 300 includes pump head 1, and the motor 2 being tightly connected with pump head 1, motor 2 is brushless electric machine, and the outer surface of motor 2 is provided with hold-down support 21.

In the present embodiment, specifically, with reference to Fig. 4, the classification of filter element 100 is connected on water route 200, specifically, from upstream It is followed successively by downstream, PP cotton filter cores, preposition activated carbon filtration core, RO membrane cartridges, post active carbon filter element.

In this embodiment, diaphragm booster pump 300 is to for preposition activated carbon filtration core, RO membrane cartridges, post active carbon filter Core is pressurized.In order to realize the control in water route 100, multiple control valves are additionally provided with water route 100.

Please with reference to Fig. 4 and Fig. 5, pump head 1 include escapement holder assembly 11, pedestal 12, diaphragm 13, piston valve base 14, Upper lid 15；Wherein,

Eccentric cam 111 includes the body 111a near motor 2, and is convexly equipped in body 111a away from the one side of motor 2 Axle portion 111b, eccentric cam 111 has the eccentric pivot hole through body 111a and axle portion 111b, the axis and axle portion of eccentric pivot hole Angular range between the axis of 111b is 3.3-3.5 degree, in Fig. 5It is shown；

Eccentric cam 111 is set in the rotating shaft 25 of motor 2 by eccentric pivot hole, and escapement bearing 112 is set in axle portion On 111b, escapement seat 1113 is set on escapement bearing 112；

Upper lid 15 is in hollow setting, and inner wall surface thereof is convexly equipped with downwards tube wall 151；

The lower end of tube wall 151 seals against with piston valve base 14, so as to by the cavity between upper lid 15 and piston valve base 14 It is partitioned into high-pressure water chamber 152 and low pressure water cavity 153.

It is fixedly connected by screw between upper lid 15, pedestal 12, the three of drive end bearing bracket 222 of motor 2.

During work, eccentric cam 111 rotates, and escapement 114 moves up and down, and the opposing pistons valve seat 14 of diaphragm 13 is expanded or received Contracting, accordingly makes the volume between diaphragm 13 and piston valve base 14 change, so as to water be sucked from low pressure water cavity 153, And extrude feeding high-pressure water chamber 152.

If diaphragm booster pump 300 adopts brush direct current motor 2, on the one hand due to the output and profile of brush motor 2 The ratio of size is relatively low, it is ensured that same output, the volume of brush motor 2 is relatively large.

On the other hand, because the brush of brush motor 2 contacts generation spark with diverter, the Electro Magnetic Compatibility of whole machine is reduced, Can also produce noise simultaneously；And because carbon brush easily weares and teares, and as use time increases, certain carbon dust can be produced, such as This, it is impossible to adapt to the space containing explosion hazard gases.

Angle between axle portion and eccentric pivot hole axis that this utility model diaphragm booster pump 300 passes through improvement eccentric cam, The amplitude of fluctuation of barrier film is increased, under the requirement of same traffic, required motor speed is low；Meanwhile, by using brushless electricity , used as power, because the output of motor 2 and the ratio of overall dimensions are high, vibration is little for machine, therefore can directly using fixed Seat 21 is fixed, and reduces noise and assembly cost.

Through experimental verification, diaphragm booster pump of the present utility model, in " voltage 12-24V, electric current≤1.5A, maximum input The experiment bar of power bracket 18-36W, operating mode (0.2MPA influent pressures, 0.5Mpa water outlet pressures), range of speeds 1200-1400rpm " Under part, flow >=600ml/min, and noise≤40dB.

Further, motor 2 includes shell 22, and the motor stator 23 and rotor 24 inside shell 22, Shell 22 includes：

Body 221, the body 221 is cylindrical in shape setting；

Drive end bearing bracket 222, the drive end bearing bracket 222 is located at one end of body 221, and drive end bearing bracket 222 is located at body 221 and pump head 1 Between；

Rear end cap 223, the rear end cap 223 is located at the other end of body 221, and rear end cap 223 integrally sets with body 221 Put.

In the present embodiment, compare existing body 221 to arrange with the split of rear end cap 223, and sealed using sealing ring, will Rear end cap 223 is wholely set with body 221, it is possible to reduce amount of parts and technique process, reduces cost, and improves motor 2 Sealing.

Further, the central authorities of the internal face of rear end cap 223 are arranged with bearing chamber 224；Motor 2 is also included located at bearing chamber 224 and the bearing 26 that is set on the output shaft 25 of motor 2.

In the present embodiment, the existing rear end cap 223 for bearing 26 being fixedly installed on and being arranged with the split of body 221 is compared On, bearing 26 is fixedly arranged in the rear end cap 223 of integral type, advantageously ensure that concentricity between bearing 26 and body 221 or Person realizes that the cost of identical concentricity standard is lower.

Preferably, motor 2 also includes circuit board 27, and circuit board 27 is fitted on the internal face of rear end cap 223 and covers axle 26 Room 224 are held, circuit board 27 is provided with the via worn for output shaft 25.Circuit board 27 is provided with drive circuit and/control electricity Road.

Further, motor stator 23 is set in the periphery of rotor 24, and with the internal face tight fit of body 221, I.e. motor 2 is inner rotor motor, and inner rotor motor is simpler with the cooperation of pump head 1, thus, assembly difficulty can be reduced.

Further, hold-down support 21 is on body 221.It is understood that the area of body 221 is relatively large, and And the center of gravity of diaphragm booster pump 300 is closer to, therefore, it is more convenient when hold-down support 21 is fixedly connected, and the company of being easily guaranteed that Connect intensity.
