DETAILED DESCRIPTION
[0040] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0041] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0042] The timing pipette provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0043] like Figures 1 to 8 As shown, an embodiment of the present application provides a timing pipette, including a gun body 100, an elastic suction nozzle 200, a suction head 300, and a detachment button 400. The elastic suction nozzle 200 is fixedly arranged at the end of the gun body 100, the suction head 300 is detachably arranged at the end of the elastic suction nozzle 200 away from the gun body 100, and the detachment button 400 is fixedly arranged at the end of the gun body 100 away from the elastic suction nozzle 200 and can be pressed to control the suction head 300 to detach from the elastic suction nozzle 200.
[0044] The detachable button 400 is provided with a timer 500 detachably, and the timer 500 is provided with a warning unit.
[0045] In an embodiment of the present application, the above-mentioned timing pipette is used, and the calibration period of the pipette is timed by a timer 500. When the calibration period of the pipette expires, the warning unit can promptly remind the staff to avoid the risk of overdue. At the same time, the timer 500 is detachably set on the detachable button 400 and does not occupy the surface space of the gun body 100, which is convenient for the operator to set the calibration period. It not only ensures the integrity of the pipette and does not interfere with the control components on the gun body 100, but also is conducive to the miniaturization of the pipette.
[0046] In a preferred embodiment, Figures 1 to 8As shown, a slot 430 capable of being plugged into the timer 500 is provided at one end of the detachment button 400 away from the gun body 100 , and a clamping hole 440 penetrating the corresponding side end surface of the detachment button 400 is provided on the inner wall of the slot 430 away from the elastic suction nozzle 200 .
[0047] Among them, a latching protrusion 510 is elastically and retractably provided on the end surface of the timer 500 away from the elastic suction nozzle 200. When the timer 500 and the slot 430 are plugged in, the latching protrusion 510 can be latched in the latching hole 440 and extend away from one end of the timer 500 to the outside of the detachment button 400.
[0048] It can be understood that during the process of inserting the timer 500 into the slot 430, the end of the latch 510 away from the timer 500 abuts against the inner wall of the slot 430 away from the elastic suction nozzle 200, and the latch 510 is in a compressed state and has elastic potential energy to extend; when the timer 500 is fully inserted into the slot 430, the latch 510 is just located at the corresponding position of the latch hole 440, and since the top pressure of the latch 510 is released, the latch 510 is reset under the action of the elastic force, and the latch 510 extends through the latch hole 440 to the outside of the detachment button 400.
[0049] Similarly, when the timer 500 is removed from the slot 430, the operator only needs to press the protruding piece 510 to retract it, thereby releasing the engagement between the timer 500 and the detachment button 400, thereby achieving the detachment of the timer 500 from the slot 430, which will not be elaborated here.
[0050] It is understandable that the detachable connection method between the release button 400 and the timer 500 is not limited to the above-mentioned one. For example, a magnetic attraction device can be directly set between the two. As long as the detachable connection between the two can be achieved and the connection reliability can be guaranteed, it will not be elaborated here.
[0051] In a preferred embodiment, Figure 4 As shown, a sliding hole 520 is provided on the end surface of the timer 500 away from the elastic suction nozzle 200, and a protrusion 510 is slidably set in the sliding hole 520, and a locking elastic member 530 is fixed between the end of the protrusion 510 close to the elastic suction nozzle 200 and the inner wall of the sliding hole 520 close to the elastic suction nozzle 200.
[0052] It is understandable that the elastic telescopic structure of the convex part 510 on the timer 500 is not limited to the above-mentioned one, as long as the convex part 510 can be snap-fitted with the clamping hole 440, which will not be elaborated here.
[0053] In a preferred embodiment, Figure 4 , Figure 5As shown, a disassembly elastic member 450 capable of abutting against the timer 500 is fixedly provided on the inner wall of the slot 430 close to the gun body 100 .
[0054] It can be understood that when the timer 500 is inserted into the slot 430 and the latch protrusion 510 is engaged with the latch hole 440, the timer 500 abuts against the disassembly elastic member 450, and the disassembly elastic member 450 is compressed and has elastic potential energy to push the timer 500 out of the slot 430. When the timer 500 is disassembled, the operator presses the latch protrusion 510 to release the engagement with the latch hole 440, and the timer 500 can automatically pop out of the slot 430 under the elastic force of the disassembly elastic member 450, thereby improving the disassembly efficiency of the timer 500.
[0055] In a preferred embodiment, Figure 7 As shown, a groove 570 is provided on the end surface of the timer 500 close to the locking protrusion 510 .
[0056] It is understandable that when the timer 500 automatically pops out of the slot 430 under the elastic force of the disassembly elastic member 450, the extraction groove 570 is located outside the slot 430. At this time, the operator can pull the timer 500 out of the slot 430 as a whole through the extraction groove 570, thereby reducing the difficulty of disassembling the timer 500.
[0057] In a preferred embodiment, Figures 4 to 6 As shown, a guide groove 420 capable of slidingly connecting with the locking protrusion 510 is provided on the inner wall of the slot 430 away from the elastic suction nozzle 200 , and both ends of the guide groove 420 are respectively connected with the locking hole 440 and the corresponding side end surface of the detachment button 400 .
[0058] It is understandable that when the timer 500 is inserted into the slot 430 , the guide groove 420 can guide the latching protrusion 510 , and the latching protrusion 510 is in a compressed state due to the resistance of the inner wall of the guide groove 420 away from the elastic suction nozzle 200 .
[0059] In a preferred embodiment, Figures 4 to 6 As shown, first chamfers are respectively provided on the inner wall of the guide groove 420 on the side away from the elastic suction nozzle 200 and about the ends of the guide groove 420 .
[0060] The end of the convex part 510 away from the timer 500 is provided with a second chamfer that can abut and cooperate with the first chamfer.
[0061] It can be understood that when the timer 500 is inserted into the slot 430 or the latch 510 is disengaged from the latch hole 440, the first chamfer on the guide groove 420 and the second chamfer on the latch 510 can be abutted to guide the latch 510 telescopically, thereby reducing interference with the detachment button 400 during loading and unloading, thereby improving the overall loading and unloading efficiency.
[0062] In a preferred embodiment, Figures 4 to 8 As shown, a through slot 410 is provided on the inner wall of the slot 430 close to the elastic suction nozzle 200 , and both ends of the through slot 410 are respectively connected to the outer surface of the detachment button 400 .
[0063] The warning unit includes a probe 580 fixedly arranged on an end surface of the timer 500 away from the protruding part 510 , and a warning light 540 is fixedly arranged on the probe 580 .
[0064] The probe 580 can be slidably connected to the through slot 410 , and when the timer 500 and the detachable button 400 are connected, the warning light 540 can emit warning light to the outer surface of the gun body 100 through the opening of the through slot 410 .
[0065] It is understandable that when the time limit set on the timer 500 expires, the warning light 540 is triggered and emits warning light to the outer surface of the gun body 100. After seeing the warning light on the surface of the gun body 100, the operator can know the time limit status of the pipette gun and perform subsequent calibration in time.
[0066] In a preferred embodiment, Figure 1 , Figure 3 As shown, a light guide bar 600 is fixedly provided on the outer surface of the gun body 100 close to the timer 500 .
[0067] The warning light 540 can emit warning light toward the end of the light guide bar 600 close to the detachment button 400 .
[0068] It is understandable that, after the warning light 540 emits warning light to the end of the light guide bar 600 , the light can be reflected inside the light guide bar 600 , so that the light guide bar 600 is illuminated as a whole, thereby improving the warning effect.
[0069] Specifically, the light guide bar 600 can be configured as an optical fiber structure, so that light can be totally reflected inside the light guide bar 600 , thereby achieving light transmission.
[0070] In a preferred embodiment, Figure 7 As shown, a display screen 550 and a control button 560 are provided on the end surface of the timer 500 close to the card protrusion 510.
[0071] Among them, the control button 560 is used to restart the countdown function after calibration, and the display screen 550 is used to display the countdown days. It displays "365 days" on the current day, and automatically jumps to "364 days" after 24 hours, and so on until it displays "0 days".
[0072] In a preferred embodiment, a transparent area is provided on the end surface of the detachment button 400 away from the elastic suction nozzle 200 .
[0073] It is understandable that when the timer 500 is inserted into the slot 430, the display information on the display screen 550 can be directly observed through the transparent area on the detachment button 400, further improving the operator's control over the calibration period of the pipette.
[0074] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.
[0075] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
