Description
Technical field
The utility model belongs to print cartridge technical field, in particular to a kind of print cartridge pressure-regulating valve structure.
Background technique
Currently, in the market existing print cartridge install use when usually because internal pressure be unable to reach with external pressure it is flat
Weighing apparatus, and the ink feeding system that often occurs is abnormal, pressure occur in print procedure excessive causes to lack color, when print procedure is stood
Pressure leakage leads to colour mixture occur, and print performance is unstable, unreliable, and print quality is decreased obviously.
Utility model content
To solve the above-mentioned problems in the prior art, the utility model provides one kind can automatically, precisely, effectively
The entrance of outside air, to adjust Ink Cartridge inner pressure balance, sealing and opening control stable, reliable print cartridge pressure-regulating valve
Structure.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of print cartridge pressure-regulating valve structure, including the air inlet set on cartridge case, mandril, dynamic clamping head and quiet clamping head is arranged in
And sealing ring；Wherein, the mandril is axially and movably inserted in air inlet, and outer end is equipped with for being sealed to air inlet
Seal head is equipped with the sealing ring between the seal head and air inlet；The inner end of the mandril be equipped with the dynamic clamping head and quiet clamping head,
To realize that mandril automatically resets and to the automatic-sealed of air inlet.
Further, the dynamic clamping head and quiet clamping head is arch shrapnel, and the arch shrapnel is mounted on the inner end of mandril, and its two
Side pressure is on shell.
Further, the dynamic clamping head and quiet clamping head is spring, and the spring pocket is on the inner end of mandril, and both ends are pressed in mandril
On shell.
Further, the outer surface of the shell is equipped with and connect with air inlet and concentric sealed groove, described close
The section constitution of end socket and mandril is T-shaped；When the automatic-sealed carried out to air inlet, the seal head and sealing ring are positioned at close
It seals in groove.
The utility model has the beneficial effects that
The utility model through the above technical solutions, can it is automatic, precisely, the entrance of effectively outside air, with adjustment
Ink Cartridge inner pressure balance, sealing and opening control stablize, are reliable, completely solve the confession through often occurring after existing print cartridge installation
Ink system is abnormal, existing print cartridge occurs that pressure is excessive to be caused to lack color, the pressure leakage when print procedure is stood in print procedure
Leading to the problem of colour mixture occur, more preferably, print quality is more preferable for print performance, and structure is simple, ingenious, and production and processing is easy,
Be conducive to high-volume to implement.
Detailed description of the invention
Fig. 1 is to use a kind of structural schematic diagram of print cartridge pressure-regulating valve constructive embodiment described in the utility model；
Fig. 2 is schematic cross-sectional view of the Fig. 1 along A-A；
Fig. 3 is the enlarged structure schematic diagram in the portion B in Fig. 2.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
It is as shown in Figure 1 to Figure 3:
A kind of print cartridge pressure-regulating valve structure described in the utility model embodiment is set on cartridge case 7 including being arranged in
Air inlet 1, mandril 2, dynamic clamping head and quiet clamping head 3 and sealing ring 4；The mandril 2 is axially and movably inserted in air inlet 1, and outer end is set
There is the seal head 5 for being sealed to air inlet 1, the sealing ring 4 is equipped between the seal head 5 and air inlet 1；Institute
The inner end for stating mandril 2 is equipped with the dynamic clamping head and quiet clamping head 3, to realize that mandril 2 automatically resets and to the automatic-sealed of air inlet 1.Its
In, the dynamic clamping head and quiet clamping head 3 can be arch shrapnel, and the arch shrapnel is mounted on the inner end of mandril 2, and its both ends is pressed in shell
On body 7；The outer surface of the shell 7 is equipped with and connect with air inlet and concentric sealed groove 6, the seal head 5 and pushes up
The section constitution of bar 2 is T-shaped；When the automatic-sealed carried out to air inlet 1, the seal head 5 and sealing ring 4 are recessed positioned at sealing
In slot 6.
When print cartridge pressure-regulating valve arrangement works described in the utility model, inflate hole 8 of the printer on cartridge case 7 is beaten
Gas, then (as schemed, after the air that printer is squeezed into enters the air cavity 10 of shell 7, air cavity 10 can be changed the inner end stress of mandril 2
Shape film 11 bulges, balance plate 12 is jacked up, is acted on the inner end of mandril 2, and the spring 13 for connecting balance plate 12 at this time is forced
Contracting.), move axially outward, seal head 5 made to leave the mating surface with sealing ring 4, while dynamic clamping head and quiet clamping head 3 is compressed, outer at this time
Portion's air enters the ink storage chamber 9 in cartridge case 7, internal pressure and the external pressure balance up to print cartridge, and mandril 2 is multiple in elasticity
It is pulled under the action of the part 3 of position, air inlet 1 is closed, is sealed up, finally make print cartridge normally out of ink.
In this way, by the utility model print cartridge pressure-regulating valve structure can it is automatic, precisely, effectively outside air into
Enter, to adjust Ink Cartridge inner pressure balance, sealing and opening control stablize, is reliable, pass through after completely solving existing print cartridge installation
The ink feeding system that often occurs is abnormal, existing print cartridge occurs that pressure is excessive to be caused to lack color, stand in print procedure in print procedure
When pressure leakage lead to the problem of colour mixture occur, more preferably, print quality is more preferable for print performance.
Certainly, the dynamic clamping head and quiet clamping head 3 is also possible to spring, and the spring pocket is on the inner end of mandril, and both ends are pressed in
On mandril and shell.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
