310 between emptying, the top for holding the part being located at immediately below spray head 1 in space 310, which is opened wide, limits open ports 3a, recyclable device
3 by open ports 3a access satellite ink droplet, and the open ports 3a being arranged as a result, facilitates satellite ink droplet entrance and holds space 310.
Specifically, holding space 310 for example, referring to Fig. 1 including first and holding space 311, first holds space 311
Horizontally disposed, the first left end top for holding space 311, which is opened wide, forms open ports 3a, and open ports 3a is located at the underface of spray head 1.
In practical application, under the airflow function of blowning installation 2, satellite ink droplet can deviate original vertical drippage direction and move right
It is dynamic, to form the motion profile that general shape is curve, therefore open ports 3a be arranged in hold space 310 be located at spray head 1
Behind the top of the part of underface, it can facilitate satellite ink droplet that can be smoothly through open ports 3a entrance and hold space 310 and returned
Receiving apparatus 3 recycles.
Optionally, referring to Fig.1, holding space 310 further includes second holding space 312, and second holds space 312 and first
It holds the right end connection in space 311 and upwardly extends the upper table wall for being through to containing part 31, first, which holds space 311 and second, contains
312 to define general shape jointly be L-shaped to hold space 310 between emptying.
Space 311 is held it is understood that holding space 310 also and can only include first, first holds space 311 to the right
It extends through to the right side wall of containing part 31.
In some embodiments of the invention, the level height of the most significant end of open ports 3a is lower than the air blowing of blowning installation 2
The level height of the least significant end of mouth 2a, thus advantageously ensures that satellite ink droplet can smoothly enter open ports 3a.
Specifically, blowning installation 2 has air blowing space 21 for example, referring to Fig. 1, air blowing space 21 includes the first air blowing
Space 211, the first air blowing space 211 is horizontally disposed, and the first air blowing space 211 is located at 1 lower section of spray head, the first air blowing space 211
Right end extend through to the right to the right side wall of blowning installation 2, so as to form inflatable mouth 2a, the thus gas in blowning installation 2
Stream can be blown out horizontally to the right from inflatable mouth 2a.
For satellite ink droplet, satellite ink droplet drops to the height of inflatable mouth 2a and disturbs with air flow contacts Shi Caihui air-flow
It moves and deviates to the right, therefore in the up-down direction, the level height of the most significant end of open ports 3a is arranged to lower than inflatable mouth 2a
Least significant end level height, advantageously ensure that satellite ink droplet can smoothly enter open ports 3a, avoid the occurrence of satellite ink droplet drop
The case where falling in the partial region of 31 left side wall of containing part being located at below open ports 3a.
Optionally, air blowing space 21 further includes the second air blowing space 212, the second air blowing space 212 and the first air blowing space
211 left end is connected to and upwardly extends the upper table wall for being through to blowning installation 2, the first air blowing space 211 and the second air blowing space
212 define general shape jointly as L-shaped air blowing space 21.
It is understood that air blowing space 21 can also only include the first air blowing space 211, the first air blowing space 211 is to the left
It extends through to the left side wall of blowning installation 2.
In some embodiments of the invention, the side wall of the neighbouring blowning installation 2 of containing part 31 is equipped with and open ports 3a
The escape port 3b of connection.Be conducive to further facilitate satellite ink droplet as a result, and be smoothly through open ports 3a and enter and holds space
310。
Specifically, the level where the roof of the side wall of the neighbouring blowning installation 2 of containing part 31 is high for example, referring to Fig. 1
Degree is lower than the level height where open ports 3a to limit escape port 3b, and structure is simple as a result, and the setting of escape port 3b
Can further facilitate satellite ink droplet can be smoothly through open ports 3a enter hold space 310.
In some embodiments of the invention, the level height of the least significant end of escape port 3b is lower than the air blowing of blowning installation 2
The least significant end level height of mouthful 2a and it is higher than the level height for holding the bottom wall in space 310.
Specifically, for example, referring to Fig. 1, in the up-down direction, the least significant end of escape port 3b is located at the least significant end of inflatable mouth 2a
With hold space 310 bottom wall between, be conducive to be further ensured that satellite ink droplet can smoothly enter open ports 3a as a result, and
And also help and the satellite ink droplet held in space 310 is stopped using the side wall where escape port 3b, it avoids because not setting
It sets the side wall where escape port 3b and satellite ink droplet is caused to flow out in space 310 under flow perturbation and fall on substrate from holding
On, and then be conducive to improve the recovering effect of recyclable device 3.
In some embodiments of the invention, recyclable device 3 can be connected with vacuum source, thus recyclable device 3 can be facilitated to return
Receive satellite ink droplet.
Specifically, holding space 310 for example, referring to Fig. 1 and being connected with vacuum source, therefore holding can shape in space 310

It is a or more than two.
Further, multiple black chambers 13 and multiple piezoelectric materials 11, multiple spray orifices 14, multiple black chambers 13 are equipped in spray head 1
It is corresponded with multiple piezoelectric materials 11, thus may make that the working condition between spray orifice 14 is independent mutually, is independent of each other.
Optionally, blowning installation 2 has multiple inflatable mouth 2a, and multiple inflatable mouth 2a and multiple spray orifices 14 correspond, by
The satellite ink droplet that this each spray orifice 14 sprays can blow to recyclable device 3 by the air-flow of corresponding inflatable mouth 2a.In concrete application, blow
Air-flow can have been blown out at port 2a always.
As some optional embodiments of the invention, blowning installation 2 has an inflatable mouth 2a, and inflatable mouth 2a is along more
The arragement direction (such as front-rear direction in figure) of a spray orifice 14 extends into strip, and thus structure is simple, is easy to implement.
Further, multiple spray orifices 14 are located between the both ends of the length direction of inflatable mouth 2a, thus can avoid having
The case where air-flow that the satellite ink droplet that a little spray orifices 14 spray can not be insufflated mouthful 2a is blown to.
In some optional embodiments of the invention, recyclable device 3 have multiple open ports 3a, multiple open ports 3a with
Multiple spray orifices 14 correspond, and air-flow of the satellite ink droplet that thus each spray orifice 14 is generated when spraying ink in inflatable mouth 2a is made
Corresponding open ports 3a can be entered under.
Optionally, recyclable device 3 has an open ports 3a, and open ports 3a is along the arragement direction (example along multiple spray orifices 14
Front-rear direction in such as figure) strip is extended into, thus structure is simple, is easy to implement.
Further, multiple spray orifices 14 are located between the both ends of the length direction of open ports 3a, thus can avoid having
A little spray orifices 14 spray the case where satellite ink droplet generated when ink cannot be introduced into open ports 3a.
