363 volumes are small as far as possible, to minimize the occupied space of eccentric stiffener 36, and then are conducive to reduce the body of pump unit 30
Product can further make to use the jetting machine of the pump unit 30 more compact, easy to carry.
In the present embodiment, high-pressure chamber 34 includes the first chamber 341 and second chamber 342 that 31 both ends of the pump housing are arranged in,
The first chamber 341 and second chamber 342 are connected with water inlet 32 and water outlet 33.Under the drive of eccentric stiffener 36,
The both ends of plunger 35 respectively in first chamber 341 and second chamber 342 in it is reciprocating, plunger 35 is handed in reciprocating motion
The extruding first chamber 341 and second chamber 342 replaced, thus make pump unit 30 it is lasting there is water to pump out, the setting is compared to list
The efficiency of the plunger pump of a chamber, water pumping is doubled, and makes pump always have a chamber to be in one cycle and is extruded
State, realize lasting water pumping.
In the present embodiment, in the side perpendicular to 35 length direction of plunger, plunger 35 is provided with the company of connection eccentric shaft 362
Socket part 351, eccentric shaft 362 are connected by interconnecting piece 351 with plunger 35, and interconnecting piece 351 is located substantially at 35 length direction of plunger
Middle position, specifically, interconnecting piece 351 is the cavity being recessed inwardly, eccentric shaft 362 passes through connection bearing 366 and interconnecting piece
351 connections, connection bearing 366 are set in the cavity of plunger 35, and eccentric shaft 362 is formed with the outer surface for connecting bearing 366 and rolled
Dynamic friction is to drive the both ends of plunger 35 reciprocating in first chamber 341 and second chamber 342.Eccentric shaft 362 and company
The connection type of socket part 351 is not limited to connection bearing 366, also may include the modes such as flat cooperation, spline fitted.In other realities
It applies in example, interconnecting piece 351 may be set to be the protrusion in the side perpendicular to 35 length direction of plunger, and eccentric shaft 362 passes through
It is connect with protrusion, straight reciprocating motion is made in first chamber 341 and second chamber 342 in the both ends of driving plunger 35.
As shown in Figure 3 and Figure 4, in the present embodiment, transmission mechanism 40 includes deceleration mechanism 401, specific deceleration mechanism 401
Planetary gear speed-reduction structure is driven to make circumference fortune when the motor output shaft 201 of motor 20 rotates for planetary gear speed-reduction structure
It is dynamic, and then planetary gear speed-reduction structure drives eccentric stiffener 36 to be rotated around its shaft, using planetary gear speed-reduction structure,
It, can be by deceleration mechanism 401 in the case where reduction ratio is certain since its sun wheel and motor output shaft 201 are fixedly installed
Volume minimization, thus keep jetting machine more compact, it is easy to carry.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
