Specific embodiment
Embodiment, as shown in Figure 1: single plunger high-pressure spray pump, including valve body 10 and water supply connector 60, motor 70.It should
Water supply connector 60 is connected to water source.
Further say:
The valve body 10 includes valve chamber 11.In the present embodiment, which is extended in the up-down direction, and is preferably in
It is cylindrical.11 top of valve chamber is equipped with intake tunnel 111, right upper portion is equipped with exhalant canal 112.The intake tunnel 111 is furnished with
One-way water inlet valve 20, the exhalant canal 112 are furnished with one-way water outlet valve 30.The upper end of the intake tunnel 111 connects the water supply connector
60.Meanwhile the piston 40 that can be moved up and down is equipped in the valve chamber 11, the lower part of the piston 40 is connected with piston rod 41, the work
The sealing cooperation of stopper rod 41 is pierced by the lower outer of the valve body 10.And the power output shaft of the motor 70 is equipped with bias
Set 71, the eccentric bushing 71 connect the lower end of the piston rod 41.That is, the eccentric bushing 71 rotation, driving should after the motor 70 work
Piston rod 41 moves up and down, which moves back and forth up and down in the valve chamber 11.When the piston 40 moves down, this is unidirectional
Inlet valve 20 is opened, the one-way water outlet valve 30 is closed, and the water in the water supply connector 60 is drawn into the valve chamber 11；When the work
When plug 40 moves up, which is closed, the one-way water outlet valve 30 is opened, and the water in the valve chamber 11 is by the work
After 40 pressurization of plug, sprayed out of this exhalant canal 112.In this way, avoiding the complex component using hydraulic cylinder, and use single living
Plug structure, greatly reduces the complexity of atomizing pump, also reduces the volume and cost of product.
Optimization:
It is arranged with bearing 72 on the eccentric bushing 71, the side of the lower end of the piston rod 41 is equipped with card slot 411, the bearing
72 outer ring is stuck in the card slot 411.In this way, making between the eccentric bushing 71 and the piston rod 41 that friction is small, more favorably
In the movement of piston 40.
The one-way water inlet valve 20 includes: that lower end is located at the water inlet that in the valve chamber 11 and upper end is located in the intake tunnel 111
Valve rod 21 is fixed on 21 upper end of water inlet valve rod in major part 22 that is bowl-shape and matching with the lower ending opening of the intake tunnel 111
Fixing sleeve 23 and both ends are respectively supported at the first back-moving spring between the fixing sleeve 23 and the lower part of the intake tunnel 111
24.Wherein: in order to cooperate with the major part 22, the diameter of the lower ending opening of the intake tunnel 111 is certainly less than the intake tunnel 111
Diameter.That is, the lower ending opening of the intake tunnel 111 is designed using beam mouth, and the major part 22 is located at the intake tunnel 111
The lower section of lower ending opening.The diameter of the major part 22 is greater than the diameter of the water inlet valve rod 21.That is, be greater than should be into for the diameter of the major part 22
The diameter of the lower ending opening of aquaporin 111, the diameter of the water inlet valve rod 21 are identical to the straight of the lower ending opening of the intake tunnel 111
Diameter.Since the lower ending opening of the intake tunnel 111 is designed using beam mouth, so the lower end of the first back-moving spring 24 can prop up
Support is in the top edge of the lower ending opening of the intake tunnel 111.The first back-moving spring 24 make the water inlet valve rod 21 have to
The trend of upper movement.In this way, the major part 22 seals the lower ending opening of the intake tunnel 111 usually；Only when the piston 40 is downward
When mobile, which overcomes the pressure of the first back-moving spring 24 to move down, and the lower ending opening of the intake tunnel 111 is beaten
It opens.
The one-way water outlet valve 30 includes: the gear of left end opening of the longitudinal section in "U" shaped and positioned at the exhalant canal 112
Water bowl 31 makes the water stopping bowl 31 have the second back-moving spring 32 for the trend that is moved to the left.Similarly, the left end of the exhalant canal 112
Opening is also designed using beam mouth.In this way, the second back-moving spring 32 forces the water stopping bowl 31 to seal the exhalant canal usually
112 left end opening；Only after the piston 40 moves up, the water with pressure makes the water stopping bowl 31 overcome the second reset bullet
The pressure of spring 32 and move right, the left end of the exhalant canal 112, which is open, opens.
Water outlet connector 33 is equipped with positioned at the right of the second back-moving spring 32 in the exhalant canal 112.The water outlet connector 33
It can deviate from out of this exhalant canal 112 to avoid the water stopping bowl 31, also can provide support for the right end of the second back-moving spring 32.
The side wall of the left end opening of the exhalant canal 112 is equipped with a pressure release passage 12.The pressure release passage 12 is furnished with pressure release
Valve 50, and the upper end opening of the pressure release passage 12 is connected to the upper end of the intake tunnel 111.
The ball sealer 51 that the relief valve 50 includes: and the lower ending opening of the pressure release passage 12 matches has the ball sealer 51
There is the third reset spring 52 for the trend of moving down.Similarly, the lower ending opening of the pressure release passage 12 is designed using beam mouth.Meanwhile
It is in horizontal step 1111 that the side of the intake tunnel 111, which can be equipped with one, and the upper end of the third reset spring 52 can support
On the step 1111, the lower end of the third reset spring 52 can be supported on a sealed ball seat 511, and the ball sealer 51 can
To be fixed on the lower part of the sealed ball seat 511.In this way, the ball sealer 51 can be upward when the pressure in the valve chamber 11 is excessive
It is mobile, so that the left end opening of the exhalant canal 112 is connected to the upper end of the intake tunnel 111, reduce rapidly in the valve chamber 11
Pressure.
Continue to optimize:
The valve body 10 is prepared using can soften integrally moulded after heating.In this way, further decreasing the difficulty of preparation
Degree.
The oil sealing 412 and/or water seal 413 that the piston rod 41 is equipped with and valve chamber 11 matches.In this way, by relatively simple
Mode realizes the sealing between the piston rod 41 and the lower part of the valve chamber 11.
A sealing body 80 is fixed on the shell of the motor 70.The sealing body 80 passes through " u "-shaped pin 90 and the valve body
10 connections, and the oil sealing 412 and/or water seal 413 are located in the sealing body 80.In this way, since " u "-shaped pin 90 is easy to disassemble,
So reducing the difficulty of product maintenance.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
