Close and do not exist, the most not within the protection domain of application claims.
The present invention proposes a kind of water purifier.
In embodiments of the present invention, as shown in Figure 4, this water purifier includes multiple filter element 100, connects multiple described filter element
The water route 200 of 100, and connect with described water route 200 and use and think the diaphragm booster pump of filter element 100 supercharging described at least
300；
Referring to figs. 1 through Fig. 3, this 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, filter element 100 classification is connected on water route 200, specifically, from upstream
It is followed successively by downstream, PP cotton filter core, preposition activated charcoal filter element, RO membrane cartridge, post active carbon filter element.
In this embodiment, diaphragm booster pump 300 is with thinking preposition activated charcoal filter element, and RO membrane cartridge, post active carbon is filtered
Core supercharging.In order to realize the control in water route 100, water route 100 is additionally provided with multiple control valve.
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 cover 15；Wherein,

During work, eccentric cam 111 rotates, and escapement 114 moves up and down, and diaphragm 13 opposing pistons valve seat 14 is expanded or receives
Contracting, makes the volume between diaphragm 13 and piston valve base 14 change accordingly, thus is sucked from low pressure water cavity 153 by water,
And extrude feeding high-pressure water chamber 152.
If diaphragm booster pump 300 uses brush direct current motor 2, on the one hand due to output and the profile of brush motor 2
The ratio of size is relatively low, it is ensured that same output, and the volume of brush motor 2 is relatively large.
On the other hand, owing to the brush of brush motor 2 contacts generation spark with diverter, reduce the Electro Magnetic Compatibility of complete machine,
The most also can produce noise；And owing to carbon brush easily weares and teares, and along with the time of use increases, certain carbon dust can be produced, as
This, it is impossible to adapt to the space containing explosion hazard gases.
Diaphragm booster pump 300 of the present invention, by improving the angle between the axle portion of eccentric cam and eccentric pivot hole axis, increases
The amplitude of fluctuation of barrier film, under the requirement of same traffic, required motor speed is low；Meanwhile, by using brushless electric machine to make
For power, owing to the output of motor 2 and the ratio of overall dimensions are high, vibrate little, therefore can directly utilize hold-down support 21
Fixing, reduce noise and assembly cost.
Through experimental verification, the diaphragm booster pump of the present invention, at " voltage 12-24V, electric current≤1.5A, maximal input
Scope 18-36W, operating mode (0.2MPA influent pressure, 0.5Mpa water outlet pressure), range of speeds 1200-1400rpm " experiment condition under,
Flow >=600ml/min, and noise≤40dB.
Further, motor 2 includes shell 22, and is located at the motor stator 23 within shell 22 and rotor 24,
Shell 22 includes:
Body 221, this body 221 is arranged in tubular；
Drive end bearing bracket 222, this drive end bearing bracket 222 is located at one end of body 221, and drive end bearing bracket 222 is positioned at body 221 and pump head 1
Between；
Rear end cap 223, this 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 and arrange with rear end cap 223 split, and use sealing ring to seal, 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 fovea centralis of the internal face of rear end cap 223 is provided with bearing chamber 224；Motor 2 also includes being 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 being fixedly installed on by bearing 26 and arranging with body 221 split is compared
On, bearing 26 is fixedly arranged in the rear end cap 223 of integral type, advantageously ensure that the concentricity between bearing 26 and body 221 or
The cost that person realizes identical concentricity standard is lower.
Preferably, motor 2 also includes that circuit board 27, circuit board 27 are fitted on the internal face of rear end cap 223 and cover axle
Holding 26 Room 224, 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 coordinating of pump head 1, so, can reduce assembly difficulty.
Further, hold-down support 21 is located on body 221.It is understood that body 221 area is relatively large, and
And it is closer to the center of gravity of diaphragm booster pump 300, therefore, more convenient when fixing connection hold-down support 21, and the company of being easily guaranteed that
Connect intensity.
