The flow control valve 500 may be a solenoid valve.
The cleaning solution supply mechanism 100 is provided with a liquid outlet 111, the cleaning mechanism 200 is provided with a cleaning cavity 231, a cleaning port 232 and a liquid inlet 233 which are communicated, two ends of the first infusion tube 300 are respectively connected with the liquid outlet 111 and the liquid inlet 233, the first liquid level detector 400 is arranged on the cleaning mechanism 200 and is used for detecting the liquid level of cleaning solution in the cleaning cavity 231, the flow control valve 500 is arranged on the first infusion tube 300 and is connected with the first liquid level detector 400, and the flow control valve 500 controls the flow of the cleaning solution in the first infusion tube 300 according to the signal of the first liquid level detector 400.
The dispensing needle head can extend into the cleaning cavity 231 from the cleaning opening 232 and then be pulled out from the cleaning cavity 231, so that the dispensing needle head can be stained with cleaning liquid in the cleaning cavity 231, the cleaning liquid covers the peripheral surface of the dispensing needle head, the cleaning liquid can corrode glue on the dispensing needle head, and residual glue on the dispensing needle head can be easily removed by wiping the dispensing needle head.
According to the cleaning solution supply mechanism 100 of the embodiment of the invention, the liquid outlet 111 is provided in the cleaning solution supply mechanism 100, the cleaning mechanism 200 is provided with the cleaning cavity 231, the cleaning port 232 and the liquid inlet 233 which are communicated, and two ends of the first infusion tube 300 are respectively connected with the liquid outlet 111 and the liquid inlet 233, so that when the dispensing needle cleaning device 1 does not work, cleaning solution can be stored in the cleaning solution supply mechanism 100, leakage of the cleaning solution is avoided, oxidation of the cleaning solution is avoided, and the cleaning solution can be prevented so as to ensure the dirt removing effect of the cleaning solution, and when the dispensing needle cleaning device 1 works, the cleaning solution can flow from the liquid outlet 111 to the liquid inlet 233, so that the cleaning solution fills the cleaning cavity 231, and the dispensing needle can be easily dipped in the cleaning solution, and the cleaning efficiency is high.
In addition, the first liquid level detector 400 is installed on the cleaning mechanism 200, and is used for detecting the liquid level of the cleaning liquid in the cleaning cavity 231, the flow control valve 500 is arranged on the first infusion tube 300 and connected with the first liquid level detector 400, and the flow control valve 500 controls the flow of the cleaning liquid in the first infusion tube 300 according to the signal of the first liquid level detector 400.
Thus, the first liquid level detector 400 can feed back the liquid level of the cleaning liquid in the cleaning cavity 231 to the flow control valve 500, when the liquid level of the cleaning liquid in the cleaning cavity 231 is lower than the cleaning port 232, the flow control valve 500 can increase the flow rate of the cleaning liquid to increase the flowing pressure of the cleaning liquid, so that the liquid level of the cleaning liquid in the cleaning cavity 231 is increased, and the dispensing needle head can be completely dipped into the cleaning liquid, so that the cleaning effect of the dispensing needle head is improved; when the cleaning liquid in the cleaning cavity 231 overflows from the cleaning port 232, the flow control valve 500 can reduce the flow of the cleaning liquid to reduce the flow pressure of the cleaning liquid, so that the liquid level of the cleaning liquid in the cleaning cavity 231 is reduced, and the cleaning liquid is prevented from overflowing, so that the cleaning liquid is prevented from polluting the root of the dispensing needle, and the cleaning effect of the dispensing needle is further improved.
Like this, through the cooperation of first liquid level detector 400 and flow control valve 500, can supply the cleaning solution when the liquid level of cleaning solution is lower, can in time reduce the liquid level of cleaning solution when the cleaning solution overflows, make the liquid level of cleaning solution maintain at a stable liquid level, guaranteed the cleaning effect to the dispensing syringe needle promptly and avoided the cleaning solution to cause the pollution again, with low costs.
Thus, the cleaning device 1 for the dispensing needle head according to the embodiment of the invention not only can avoid overflow of cleaning liquid, but also has the advantages of stable liquid level of the cleaning port 232, good cleaning effect and the like.
In some embodiments of the present invention, as shown in fig. 1 and 2, the dispensing needle cleaning device 1 further comprises a one-way valve 510.
The check valve 510 is connected to the first infusion tube 300, the liquid inlet 233 is located below the cleaning chamber 231, the cleaning opening 232 is located above the cleaning chamber 231, and the check valve 510 allows the cleaning liquid to flow from the liquid outlet 111 to the cleaning chamber 231 and prevents the cleaning liquid from flowing from the cleaning chamber 231 to the liquid outlet 111.
It can be appreciated that after the cleaning solution enters the cleaning cavity 231 from the liquid inlet 233, the cleaning solution has a downward flowing trend under the influence of gravity, and the cleaning opening 232 is formed above the cleaning cavity 231, so that the cleaning solution cannot overflow from the cleaning opening 232 when the liquid level of the cleaning solution is not higher than that of cleaning, the cleaning cavity 231 can accommodate more cleaning solution, and the dispensing needle head is generally dispensed downwards, so that the lower end of the dispensing needle head is more required to be cleaned, and the lower end of the dispensing needle head is easier to extend into the cleaning cavity 231 through the cleaning opening 232, thereby facilitating cleaning of the dispensing needle head.
In addition, by providing the check valve 510, the cleaning liquid does not flow back to the cleaning liquid supply mechanism 100 after flowing through the check valve 510, that is, the cleaning liquid in the cleaning cavity 231 does not flow back, so that the liquid level of the cleaning liquid in the cleaning cavity 231 can be maintained near the cleaning port 232 more stably, the liquid level of the cleaning liquid is kept stable, and the dispensing needle is convenient to pick up the cleaning liquid.
Further, as shown in fig. 1 and 2, the check valve 510 is located between the flow control valve 500 and the cleaning chamber 231, so that the flow control valve 500 can control the flow of the first infusion tube 300 according to the signal fed back by the first liquid level detector 400, the quantitative cleaning liquid can enter the cleaning chamber 231 through the check valve 510, and when the flow of the cleaning liquid pumped out by the liquid outlet 111 is large, the flow control valve 500 can directly seal off the excessive cleaning liquid, so that the cleaning liquid can return to the cleaning liquid supply mechanism 100 through the liquid outlet 111, thereby avoiding the excessive cleaning liquid from being blocked between the flow control valve 500 and the check valve 510, and being more beneficial to controlling the liquid level in the cleaning chamber 231.
In some embodiments of the present invention, as shown in fig. 1 and 2, the cleaning mechanism 200 includes a main body 210, a liquid reservoir 220, and a cleaning tube 230.
The liquid storage tank 220 is mounted on the main body 210 and is configured with a liquid storage cavity 221 and an opening 222 communicated with the liquid storage cavity 221, the cleaning pipe 230 is positioned in the liquid storage cavity 221 and is configured with a cleaning cavity 231, a cleaning port 232 and a liquid inlet 233, the liquid inlet 233 penetrates through the bottom wall of the liquid storage cavity 221, and the cleaning port 232 is exposed from the opening 222.
Specifically, the cleaning solution directly enters the cleaning cavity 231 through the first infusion tube 300 and the liquid inlet 233, the cleaning port 232 is exposed from the opening 222, the dispensing needle head can extend into the cleaning cavity 231 through the opening 222 and the cleaning port 232 to be dipped with the cleaning solution, when the cleaning solution overflows the cleaning port 232, the cleaning solution can flow into the liquid storage cavity 221 of the liquid storage tank 220 through the opening 222, so that the cleaning solution is prevented from polluting the ground, polluting other parts of the dispensing needle head cleaning device 1 or parts of the dispensing needle head, which do not need cleaning.
For example, the cleaning tube 230 may be integrally formed with the bottom wall of the liquid storage chamber 221, or the cleaning tube 230 and the liquid storage tank 220 may be separately manufactured and assembled together, and the connection between the cleaning tube 230 and the liquid storage tank 220 is kept sealed, and the liquid storage chamber 221 is used for collecting the cleaning liquid overflowed from the cleaning opening 232 and preventing the cleaning liquid from leaking.
In some embodiments of the present invention, as shown in fig. 1 and 2, the inner diameter of the opening 222 is greater than the outer diameter of the cleaning tube 230.
That is, the inner circumferential surface of the opening 222 is spaced apart from the outer circumferential surface of the cleaning tube 230 such that a gap exists between the side wall of the opening 222 and the cleaning tube 230, and when the cleaning liquid overflows from the cleaning port 232, the cleaning liquid can flow into the liquid storage chamber 221 through the gap between the side wall of the opening 222 and the cleaning tube 230, preventing the cleaning liquid from flowing to the outside of the liquid storage tank 220.
Also, the upper surface of the liquid storage tank 220 is not lower than the upper end surface of the cleaning tube 230, that is, the upper side surface of the opening 222 is not lower than the cleaning port 232, for example, the upper side surface of the opening 222 may be flush with the cleaning port 232, or the upper side surface of the opening 222 may be higher than the cleaning port 232, so that the cleaning liquid overflowed from the opening 222 may be lower than the opening 222, thereby allowing the cleaning liquid to flow from the opening 222 into the liquid storage chamber 221, and further reducing the possibility of the cleaning liquid overflowing.
In some embodiments of the present invention, as shown in fig. 4, the liquid storage tank 220 further includes a liquid drain port 223, wherein the liquid drain port 223 is provided at the bottom wall of the liquid storage tank 220 and is in communication with the liquid storage chamber 221, and the liquid drain port 223 is in communication with the return port 112 of the cleaning liquid supply mechanism 100 through the second liquid delivery pipe 310.
Specifically, the liquid outlet 223 can be arranged at the lowest position of the bottom wall of the liquid storage tank 220, and the liquid outlet 223 and the liquid inlet 233 are arranged at intervals, so that the liquid outlet 223 and the liquid inlet 233 are prevented from being interfered, and therefore cleaning liquid in the liquid storage cavity 221 can be gathered to the liquid outlet 223 and flows back to the cleaning liquid supply mechanism 100 through the liquid outlet 223 and the second liquid conveying pipe 310, recovery of the cleaning liquid is achieved, waste of the cleaning liquid is reduced, the cleaning liquid cannot stay in the liquid storage cavity 221 for too long time, excessive accumulation and overflow of the cleaning liquid in the liquid storage cavity 221 are avoided, and pollution caused by the cleaning liquid is further avoided.
Further, as shown in fig. 4, the cross-sectional area of the drain port 223 gradually decreases in a direction away from the liquid reservoir 220. That is, the sidewall of the liquid outlet 223 may be inclined, so that on one hand, the cross-sectional area of the upper end of the liquid outlet 223 may be increased, and the cleaning liquid may more easily enter the liquid outlet 223, on the other hand, the sidewall of the liquid outlet 223 may have a flow guiding function, so as to increase the flow rate of the cleaning liquid, thereby increasing the backflow efficiency of the cleaning liquid in the liquid storage cavity 221, and enabling the cleaning liquid to quickly flow back to the cleaning liquid supply mechanism 100.
Further, as shown in fig. 1, 2 and 4, the cleaning mechanism 200 further includes a second liquid level detector 410, where the second liquid level detector 410 is disposed in the liquid storage tank 220, and is configured to detect the liquid level of the cleaning liquid in the liquid storage chamber 221.
For example, the second liquid level detector 410 may be provided with a preset value, where the liquid level corresponding to the preset value is higher than the liquid inlet 233 and lower than the opening 222, and when the liquid level of the cleaning liquid in the liquid storage cavity 221 reaches the preset value, an alarm is sent, and a worker can determine that the cleaning liquid in the cleaning cavity 231 stays through the alarm, that is, the cleaning liquid in the cleaning cavity 231 is not timely discharged through the liquid outlet 223, and check the liquid storage tank 220 and the second liquid delivery pipe 310, so as to avoid the blockage of the liquid outlet 111 or the second liquid delivery pipe 310, and thus more reliably prevent the cleaning liquid from overflowing from the liquid storage cavity 221.
In some embodiments of the present invention, as shown in FIG. 4, the cleaning tube 230 includes a main body section 234 and a deflector section 235.
The main body section 234 extends in a vertical direction and defines a liquid inlet 233, the flow guiding section 235 is connected with an upper end of the main body section 234 and defines a cleaning opening 232, and an outer contour of a cross section of the flow guiding section 235 gradually decreases in a direction away from the main body section 234. Wherein the cleaning chamber 231 penetrates the main body section 234 and the deflector section 235.
Thus, the main body section 234 can increase the length of the cleaning tube 230, so that the cleaning tube 230 can penetrate through the liquid storage cavity 221 and be exposed from the opening 222, and the space of the cleaning cavity 231 is large enough, so that when the dispensing needle can extend into the cleaning tube 230, the cleaning cavity 231 can completely accommodate the portion of the dispensing needle, which needs cleaning, so that the dispensing needle can be fully stained with the cleaning liquid in the cleaning cavity 231. Moreover, the outer peripheral surface of the guiding section 235 can guide the cleaning liquid, if the cleaning liquid overflows from the cleaning opening 232, the cleaning liquid can flow to the opening 222 and enter the liquid storage cavity 221 along the outer peripheral surface of the guiding section 235 under the action of gravity, so that the cleaning liquid is further prevented from flowing to the outside of the liquid storage tank 220, and the cleaning liquid is prevented from polluting the dispensing needle cleaning device 1.
In addition, the end of the guiding section 235 facing away from the main body section 234 may be a horizontal plane, that is, the end of the guiding section 235 facing away from the main body section 234 may be flush with the cleaning opening 232, so that when the liquid level of the cleaning liquid is flush with the cleaning opening 232, the horizontal plane structure of the end of the guiding section 235 facing away from the main body section 234 may keep the liquid level, thereby stabilizing the liquid level of the cleaning liquid.
In some embodiments of the present invention, as shown in fig. 4 and 6, the outer circumferential surface of the 235 deflector segment is gradually inclined from bottom to top toward the central axis of the cleaning tube 230.
