Description

Technical Field

[0001] This application relates to the technical field of biological detection. Specifically, it relates to a detection instrument. Background Art

[0002] In the field of biological detection, detection instruments usually require a light-shielded environment when performing detection functions. Therefore, operators need to load the sample into the instrument, close the lid, and then start the detection function, or end the detection function before opening the lid and taking out the sample. To assist operators in starting or interrupting the detection, detection instruments are usually equipped with detection buttons on the outside to assist in starting and closing the detection work of the instrument.

[0003] However, relying solely on operators to follow the operating specifications and click the detection button to start the detection work after confirming that the detection instrument lid is closed is unreliable. When the instrument is in the open-lid state, operators may accidentally touch the detection button when loading or taking out the sample, resulting in the incorrect start of the detection work; after loading the sample, operators may also forget to close the lid and click the detection button. If the detection instrument is started and performs detection work in a non-light-shielded environment, it will cause incorrect detection results and affect the detection quality.

[0004] Therefore, there is an urgent need for a new type of detection instrument that will not directly start the detection work even if the detection button is accidentally touched in the open-lid state, so as to improve the detection quality and the reliability of the detection work. Utility Model Content

[0005] The purpose of this application is to provide a detection instrument that can cooperate with the lid-closed detection component and the detection switch component to reduce the problem of incorrect start of the detection work due to accidental touch of the switch in the open-lid state of the detection instrument, and effectively improve the detection quality and work reliability of the detection instrument.

[0031] The technical solution of the present application will be described in detail below with reference to the drawings.

[0032] Please refer to Figures 1 to 3 , Figure 1 which is a schematic diagram of the overall structure of the detection instrument 1 shown in an embodiment of the present application in the cover-closed state; Figure 2Schematic diagram of the overall structure of the detection instrument 1 in the open cover state shown in an embodiment of the present application; Figure 3 Schematic cross-sectional view of the overall detection instrument 1 shown in an embodiment of the present application. As Figures 1 to 3 shown, the present application provides a detection instrument 1, including a body 11, a machine cover 12, a biological detection component 40, a detection switch component 20, and a cover closing detection component 30.

[0033] Among them, the machine cover 12 is pivotally mounted on the body 11 in an openable and closable manner; the biological detection component 40 is arranged in the body 11; the detection switch component 20 is arranged on the body 11 and / or the machine cover 12, and the detection switch component 20 is electrically connected to the biological detection component 40; the cover closing detection component 30 is arranged on the body 11 and is electrically connected to the biological detection component 40, and the cover closing detection component 30 has the function of identifying the closing of the detection instrument 1.

[0034] In the embodiment of the present application, the detection instrument 1 identifies whether it is in the closed cover state through the cover closing detection component 30, that is, it means that the detection instrument 1 detects whether the machine cover 12 is accurately buckled or accurately mounted on the body 11 through the cover closing detection component 30. When the detection instrument 1 identifies that it is in the closed cover state through the cover closing detection component 30, the detection instrument 1 will control the biological detection component 40 to start the detection work (or maintain the closed state) according to the electrical signal sent by the detection switch component 20. Thus, in the above technical solution, the detection instrument 1 can reduce the probability of mis-starting the detection work caused by accidental pressing of the detection switch in the open cover state through the coordinated setting of the cover closing detection component 30 and the detection switch component 20, and improve the detection quality and detection reliability of the detection instrument 1.

[0035] In some embodiments, the machine cover 12 can be pivotally connected to one side edge of the body 11 through a rotating shaft, and the machine cover 12 can also be set as a separable cover body, and then detachably buckled on one end of the body 11. In some embodiments, the detection switch component 20 can be connected to the body 11, can be connected to the machine cover 12, or can be partially arranged on the body 11 and partially arranged on the machine cover 12. The detection switch component 20 can select various types of switch components such as a push-type induction button, a touch-type induction button, an infrared induction switch, or a photoelectric induction switch. In some embodiments, the detection instrument 1 provided by the present application can be applied to various detection application scenarios such as single test tube, 4 test tubes, 8 test tubes, 24 test tubes, 96 test tubes, etc., and the specific size of the detection instrument 1 can be determined according to the test tube capacity.

[0036] In some embodiments, the pressing trigger direction A corresponding to the detection switch component 20 is perpendicular to the placement surface 100 of the body 11. The placement surface refers to the surface that plays a supporting role or a connection and fastening role when the detection instrument 1 is actually placed or installed at a certain fixed position. Figure 3For example, when the detection instrument 1 is placed independently at a certain position, the placement surface 100 is the bottom surface of the body that serves as a support. When the side wall of the body of the detection instrument 1 is connected to a side-standing wall or other side-standing mounting plate through fasteners such as bolts, the placement surface of the detection instrument 1 is the side wall of the body that serves as a connection and fastening function. At this time, the pressing trigger direction corresponding to the detection switch assembly 20 can also be perpendicular to the placement surface.

[0037] In the embodiment of the present application, when the switch type selected for the detection switch assembly 20 is a push-type induction button, the pressing trigger direction corresponding to the detection switch assembly 20 is perpendicular to the placement surface 100 of the body 11, which is beneficial for the operator to click the button more conveniently and can reduce the occurrence of the detection instrument 1 moving or shaking, improving the connection reliability or placement stability of the body 11; further, the above technical solution can also improve the situation of the sample shaking or even splashing out, improving the detection quality. For the detection instrument 1 provided in the present application, the operator can perform the button clicking action with one hand without using the other hand to hold the body 11 of the detection instrument 1 to reduce movement or shaking. In addition, as Figures 1 to 3 shown, when the detection switch assembly 20 is provided on the top of the body 11, the exposed end face 200 of the detection switch is easier to identify, which is beneficial for the operator to find and operate.

[0038] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the detection switch assembly 20 shown in an embodiment of the present application. Please combine with Figures 3 to 4 shown, the detection switch assembly 20 includes a movable button 21 and an elastic button 22. Among them, the elastic button 22 is arranged inside the body 11, and the movable button 21 is movably arranged on one side of the elastic button 22; when the movable button 21 moves towards the elastic button 22 and abuts against the elastic button 22, the elastic button 22 is pressed and can generate a start trigger signal.

[0039] In the embodiment of the present application, when the movable button 21 is in a pressed state, it moves towards the elastic button 22 and abuts against the elastic button 22, so that the elastic button 22 is pressed to generate a start trigger signal. When the movable button 21 is not pressed, it automatically returns to the initial position through the elastic action of the elastic button 22 for the next click, which can improve the convenience of using the detection instrument 1. In the above technical solution, the overall structure of the detection switch assembly 20 is simple and compact, which is beneficial for arranging and installing in all directions of the detection instrument 1.

[0040] Please combine with Figures 3 to 4 shown, in some embodiments, the movable button 21 is movably arranged on the machine cover 12, and the elastic button 22 is arranged inside the body 11; when the machine cover 12 is buckled with the body 11, the axes of the movable button 21 and the elastic button 22 coincide.

[0041] In the embodiment of the present application, the axes of the movable button 21 and the elastic button 22 coincide, so that when the detection instrument 1 is in the closed cover state, the movable end and the sensing end of its detection switch assembly 20 can be exactly aligned to achieve the transfer of pressing force, and there is no need for wire connection when the movable end and the sensing end of the detection switch assembly 20 are respectively arranged on the machine cover 12 and the machine body 11. Thus, there is no need to additionally arrange a circuit board 23 or wires in the machine cover 12 of the detection instrument 1, effectively reducing the weight of the machine cover 12; when the machine cover 12 and the machine body 11 are pivotally connected by a rotating shaft, there is no need to arrange wires to pass through the pivoting area, thereby reducing problems such as wire aging, breakage, and poor durability caused by repeated pulling of wires during the opening and closing of the detection instrument 1, reducing the maintenance times of the detection instrument 1, extending the service life of the detection instrument 1, and improving the use efficiency of the detection instrument 1.

[0042] Please refer to Figures 5 to 6 , Figure 5 is a partial cross-sectional view of the detection instrument 1 when the movable button 21 is not pressed as shown in an embodiment of the present application; Figure 6 is a partial cross-sectional view of the detection instrument 1 when the movable button 21 is pressed as shown in an embodiment of the present application. Please refer to Figures 3 to 6 As shown, the machine cover 12 includes a machine cover housing 121 and a sealing plate 122, and the sealing plate 122 is arranged on the side of the machine cover housing 121 close to the machine body 11; the machine body 11 includes a machine body 111 and a machine body cover plate 112, and the machine body cover plate 112 is arranged on the side of the machine body 111 close to the machine cover 12. Among them, the machine cover housing 121 and the sealing plate 122 form a first empty space 120, and the machine body cover plate 112 and the machine body 111 form a second empty space 110 capable of accommodating the biological detection component 40. In some embodiments, the machine body cover plate 112 and the machine body 111 can be integrally formed, and the machine cover housing 121 and the sealing plate 122 can be connected by a buckle.

[0043] In some embodiments, the closed cover detection component 30 includes a Hall detection component 31 and a magnetic component 32. Among them, the Hall detection component 31 can be connected to the machine body 11, and the magnetic component 32 can be connected to the machine cover 12; when the machine cover 12 and the machine body 11 are accurately buckled, the Hall detection component 31 can exactly sense the magnetic component 32 and generate a closed cover trigger signal.

[0044] In the embodiments of the present application, the magnetic member 32 can be a magnetic steel. The magnetic member 32 can be disposed in the first vacant position 120 and connected to the sealing plate 122; the magnetic member 32 can also be disposed on the surface of the detection plate close to the body 11 and connected to the detection plate. In some embodiments, only when the machine cover 12 is completely fastened to the body 11 can the Hall detection member 31 detect the magnetic member 32, that is, only at this time is the magnetic member 32 within the sensing range of the Hall detection member 31. In the above technical solution, the detection instrument 1 determines whether it is in the closed cover state according to whether the Hall detection member 31 can sense the magnetic member 32, so as to alleviate or even solve the problem of incorrect start of the detection work caused by accidental pressing or touching of the elastic button 22 or the detection switch assembly 20 in the open cover state, thereby improving the detection quality and reliability of the detection instrument 1.

[0045] In some embodiments, the movable button 21 includes a button unit 211 and an elastic member 212. One end of the elastic member 212 abuts against the button unit 211, and the other end of the elastic member 212 abuts against the sealing plate 122. In the embodiments of the present application, the movable button 21 itself can also be automatically reset by the elastic member 212. The above technical solution can improve the problem that the movable button 21 cannot be completely reset due to the limited rebound stroke of the elastic button 22 itself, improve the flexibility of the compression and rebound of the movable button 21, and improve the user experience. In some embodiments, the elastic member 212 can be a spring, and the spring can be sleeved outside the connecting rod portion 2112. One end of the spring abuts against the button portion 2111, and the other end abuts against the sealing plate 122. After the movable button 21 is assembled to the machine cover 12, the spring can be in a semi-compressed state without external force.

[0046] In some embodiments, the button unit 211 includes a button portion 2111 and a connecting rod portion 2112. Among them, one end of the connecting rod portion 2112 is coaxially connected to the button portion 2111, and the other end of the connecting rod portion 2112 passes through the first through hole 1220 on the sealing plate 122 and is close to (abutting or adjacent to) the elastic button 22. The outer diameter of the button portion 2111 is greater than the inner diameter of the first through hole 1220. In the embodiments of the present application, the button unit 211 can realize the force conduction from the movable button 21 to the elastic button 22 through the arrangement that the connecting rod portion 2112 passes through the first through hole 1220; the inner diameter of the first through hole 1220 is smaller than the outer diameter of the button portion 2111, so that the button unit 211 will not fall off from the machine cover 12 into the body 11 through the first through hole 1220 when being pressed excessively.

[0047] In some embodiments, along the axial direction of the button portion 2111, the height h3 of the first vacant space 120 located between the machine cover housing 121 and the sealing plate 122 is less than the height h1 of the button portion 2111. In the embodiments of the present application, the height of the button portion 2111 being greater than the height of the first vacant space 120 can reduce the probability that the key unit 211 is stuck by the inner wall of the machine cover housing 121 and is difficult to be restored after being pushed into the first vacant space 120, and improve the rebound reliability of the movable button 21.

[0048] In some embodiments, the machine cover housing 121 has a second through hole 1210, and one end of the button portion 2111 is movably received in the second through hole 1210, and the other end of the button portion 2111 abuts against the machine cover housing 121 through a limiting step surface 2110 or a limiting protrusion 2113. In the above technical solution, the arrangement of the limiting step surface 2110 or the limiting protrusion 2113 limits the movable distance of the key unit 211 rebounding towards the outside of the machine body 11, thereby reducing the probability that the movable button 21 falls off the detection instrument 1 from inside the machine cover 12 through the second through hole 1210, and improving the connection reliability and stability of the detection switch assembly 20.

[0049] In some embodiments, along the axial direction of the button portion 2111, the height h2 between the exposed end surface 200 of the button portion 2111 and the limiting step surface 2110 or the limiting protrusion 2113 does not exceed the height h4 of the second through hole 1210. Specifically, the height h2 between the exposed end surface 200 of the button portion 2111 and the limiting step surface 2110 or the limiting protrusion 2113 can be equal to the height h4 of the second through hole 1210, so that when the movable button 21 is in an un-pressed state, its exposed end surface 200 is flush with the outer surface of the machine cover 12.

[0050] In the embodiments of the present application, the exposed end surface 200 of the button portion 2111 is the exposed end surface of the detection switch assembly 20. The exposed end surface 200 of the button portion 2111 generally refers to the surface directly touched when the user clicks or contacts the detection switch, or can also refer to the surface exposed outside the detection instrument 1 by the detection switch. The height between the exposed end surface 200 and the limiting protrusion 2113 generally refers to the axial distance between the position or area on the limiting protrusion 2113 that substantially plays a limiting and abutting role and the exposed end surface 200. In the above technical solution, the height between the exposed end surface 200 and the limiting step surface 2110 or the limiting protrusion 2113 not exceeding the height of the second through hole 1210 makes the exposed end surface 200 of the button portion 2111 lower than the outer surface of the machine body 11 or the machine cover 12, or makes the exposed end surface 200 of the button portion 2111 flush with the outer surface of the machine body 11 or the machine cover 12, thereby reducing the probability that the detection switch assembly 20 is accidentally touched and causing the detection work to be accidentally started, and improving the reliability of the detection instrument 1 in use.

[0051] In some embodiments, the elastic key 22 can directly select the trigger key 221 with a rebound function; in some embodiments, the elastic key 22 can also include a trigger key 221 and a key gasket 222. Among them, the trigger key 221 is connected to the circuit board 23, and the circuit board 23 is disposed in the second vacant position 110 and connected to the body cover 112. When the machine cover 12 and the machine body 11 are accurately aligned and fully latched, the trigger key 221, the key gasket 222, and the key unit 211 are coaxially arranged.

[0052] In some embodiments, a third through hole 1120 is provided on the body cover 112, and the key gasket 222 is disposed between the trigger key 221 and the connecting rod portion 2112, and the key gasket 222 is limited between the body cover 112 and the trigger key 221 by the step surface in the third through hole 1120. In some embodiments, the trigger key 221 can be a small-stroke key, which can generate a start trigger signal and make a clicking sound only after receiving a certain pressure. After the trigger key 221 is pressed, if no pressure is continuously applied thereto, it will automatically rebound and return to its original position.

[0053] In some embodiments, the Hall detection component 31 and the trigger key 221 are connected to the same circuit board 23, and the circuit board 23 is electrically connected to the controller of the biological detection component 40 or the main control chip of the detection instrument 1. The detection instrument 1 will only control the biological detection component 40 to start the detection work when both the start trigger signal and the lid-closure trigger signal are received.

[0054] Please refer to Figures 1 to 6 As shown, in the non-working state, each part in the detection switch assembly 20 is in the initial position and the initial state. The elastic member 212 is in a semi-compressed state. Under the combined action of the limit step surface 2110 (or the limit protrusion 2113) and the elastic member 212 in the movable key 21, the limit step surface 2110 (or the limit protrusion 2113) of the key unit 211 in the movable key 21 abuts against the inner wall of the machine cover housing 121, and the exposed end surface 200 is flush with the outer surface of the machine cover 12. The top surface of the key gasket 222 is flush with the body cover 112 under the supporting action of the trigger key 221 and the limiting action of the step surface in the third through hole 1120.

[0055] When using the detection instrument 1, turn or move the machine cover 12 away from the machine body 11 to open the machine cover 12, place the test tube containing the sample into the biological detection component 40 in the second vacant position 110, and then accurately align and fully latch the machine cover 12 to the machine body 11 so that the detection instrument 1 is in the lid-closed state. At this time, the Hall detection component 31 can detect the magnetic member 32 and generate a lid-closure trigger signal, and the Hall detection component 31 sends the lid-closure trigger signal to the controller of the biological detection component 40 or the main control chip of the detection instrument 1 through the circuit board 23.

[0056] When it is necessary to start the detection work of the detection instrument 1, the button unit 211 can be pressed to move it towards the trigger button 221. During the process of the button unit 211 moving towards the trigger button 221, the elastic member 212 is compressed, and the connecting rod portion 2112 abuts against the button gasket 222, and then the pressure is transmitted towards the trigger button 221 through the button gasket 222. When the pressure received by the trigger button 221 reaches a certain magnitude or the trigger button 221 reaches a certain stroke, it is triggered, generating a start trigger signal and making a sound. The trigger button 221 transmits the start trigger signal to the controller of the biological detection component 40 or the main control chip of the detection instrument 1 through the circuit board 23. When the controller of the biological detection component 40 or the main control chip of the detection instrument 1 receives the start trigger signal and the lid closing trigger signal simultaneously, it will control the biological detection component 40 to start the detection work.

[0057] When the button unit 211 is released and no pressure is applied to it anymore, the automatic rebound function of the trigger button 221 makes itself return to the initial state. At the same time, the button gasket 222 is pushed to the initial position by the rebound force of the trigger button 221. During the process of the elastic member 212 rebounding to restore to the initial semi-compressed state, it pushes the button unit 211 to move in the direction away from the trigger button 221. The button unit 211 abuts against the inner wall of the machine cover housing 121 again through the limit protrusion 2113 or the limit step surface 2110 under the action of the thrust, and the button unit 211 returns to the initial position, and its exposed end face 200 is flush with the outer surface of the machine cover 12.

[0058] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
