If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.
Referring to fig. 1, the darkroom assembly of the first embodiment of the present invention comprises a darkroom main body 100, a detecting device 200, a first light shielding member 300 and a first driving mechanism 400, wherein the darkroom main body 100 is used for placing a sample to be detected and is matched with a darkroom door 700 to provide a dark environment required for detection. The detection device 200 is used for detecting a sample. The first light-shielding member 300 can be driven by the first driving mechanism 400, so as to shield the detection end 210 of the detection device 200 when the dark room door 700 is opened, reduce the damage of the external light to the detection end 210, and prolong the service life of the detection device 200.
The darkroom main body 100 is used for placing a sample to be detected, and as shown in the figure, the darkroom main body 100 can be a box body structure with a roughly rectangular shape, a cavity 110 is arranged in the darkroom main body 100, and the sample can be placed in the cavity 110 for detection. The cavity 110 forms a first opening 120 on the darkroom main body 100, and the first opening 120 is used for allowing the sample to enter and exit the first opening 120 of the cavity 110, and the shape of the first opening is similar to the shape of the sample and is slightly larger than the sample, so that the sample can be conveniently entered and exited. It can be understood that the sample is usually stored or attached to a carrier such as a sample container, for example, the gas collection card 900 shown in fig. 2, so that the first opening 120 is a rectangular opening with a corresponding shape, the dimension in the length direction (left-right direction in fig. 2) of the rectangular opening is larger than the dimension in the width direction (left-right direction in fig. 2) of the gas collection card 900, and the dimension in the width direction (front-back direction in fig. 2) of the first opening 120 is larger than the dimension in the thickness direction (front-back direction in fig. 2) of the gas collection card 900, so that the gas collection card can pass through the first opening 120 without being obstructed. In addition, the first opening 120 may be disposed at the top of the darkroom main body 100, so that the gas collecting card 900 may slide in the cavity 110 along the vertical direction under the action of gravity, and the gas collecting card 900 may reach a preset detection position.
Referring to fig. 2 and 3, the darkroom main body 100 further has a detection channel 130 communicated with the cavity 110, the detection channel 130 forms a second opening 131 on the inner wall surface of the darkroom main body 100, wherein the detection channel 130 is disposed corresponding to the detection end 210 of the detection device 200, and has a shape similar to the shape of the detection end 210, for example, when the detection end 210 is a cylinder, the detection channel 130 corresponds to a circular channel. The detecting channel 130 may be slightly larger than the detecting end 210 so that the detecting end 210 can be inserted into the detecting channel 130, and when the detecting end 210 extends into the detecting channel 130, the distal end surface of the detecting end 210 may be flush with the inner wall surface of the darkroom main body 100 having the second opening 131, or may be lower than the inner wall surface, but usually does not extend out of the inner wall surface, so that the first light shielding member 300 achieves a better shielding effect.
Generally, the first opening 120 and the detection channel 130 are disposed on different sides of the darkroom main body 100, for example, the first opening 120 is disposed on the top of the darkroom main body 100, and the detection channel 130 is disposed on the side of the darkroom main body 100, so that the gas collection card 900 falls into the bottom of the cavity 110 due to gravity, thereby facilitating the alignment of the sample-carrying region on the gas collection card 900 with the detection end 210 of the detection device 200.
Referring to fig. 1 and 2, the darkroom main body 100 may be a split structure, and includes a first housing 170 and a second housing 180, wherein the cross sections of the first housing 170 and the second housing 180 are substantially U-shaped, that is, the first housing 170 includes a first base plate and a first side plate, and two opposite sides of the first base plate are connected to the first side plate; correspondingly, the second casing includes second base plate and second curb plate, and the relative both sides of second base plate all are connected with the second curb plate. During assembly, the first side plate is abutted against the corresponding second side plate and is defined by the threaded fastener, so that the cavity 110 and the first opening 120 are enclosed among the first base plate, the first side plate, the second base plate and the second side plate. As shown in the drawing, the sensing passage 130 is formed on the first housing 170, and the sensing device 200 is connected to the first housing 170. Compared with the mode of directly processing the cavity 110, the first shell 170 and the second shell 180 which are designed in a split type can be processed separately, so that the processing difficulty is reduced, a complex structure is conveniently formed on the cavity wall of the cavity 110, and certainly, the darkroom main body 100 can also be an integrated structure.
The detecting device 200 can be a well-known structure, such as a photomultiplier tube, which includes a main structure and a detecting end 210 connected to one end of the main structure, the detecting end 210 usually has a detecting element sensitive to strong light, such as a photocathode, etc., so that the detecting end 210 should be in a weak light or dark environment as much as possible. The detecting end 210 is disposed through the detecting channel 130, and the main structure is located outside the darkroom main body 100. In order to connect the detection device 200 to the darkroom main body 100, the detection device 200 may further include a mounting housing 220, the mounting housing 220 is a cylindrical structure adapted to the shape of the main body, and has a mounting flange 221 at one end facing the darkroom main body 100, and the mounting flange 221 is provided with a threaded hole. When installed, the main structure is located in the installation housing 220, the detection end 210 extends out of the installation housing 220, and the installation flange 221 is engaged with the outer side surface of the darkroom main body and locked by a threaded fastener. The installation flange 221 and the darkroom main body 100 can be shielded from light by a step surface or by additionally arranging a light shielding pad, so that light is prevented from leaking into the cavity 110.
The first light shielding member 300 cooperates with the first driving mechanism 400, the first light shielding member 300 is located in the cavity 110 and connected to the darkroom main body 100, and the first driving mechanism 400 drives the first light shielding member 300 to move to close or open the second opening 131, so as to close or open the detection channel 130. Referring to fig. 4 and 5, when the first light-shielding member 300 closes the second opening 131, strong light outside the dark room door 700 after opening can be prevented from damaging sensitive devices in the detection end 210; when the first light shielding member 300 opens the second opening 131, no obstruction exists between the detecting end 210 and the sample, and the detecting device 200 can detect the sample. The term "the first light shielding member 300 closes or opens the second opening 131" should be understood in a broader sense, and may be that the first light shielding member 300 completely shields the second opening 131, that is, the first light shielding member 300 completely fits to the inner wall surface having the second opening 131, or that a certain gap exists between the first light shielding member 300 and the inner wall surface, the reason for this is that the detection end 210 is located in the cavity 110 of the darkroom main body 100, the wall of the darkroom main body 100 can play a certain role of shading light, even if the dark room door 700 is in an open state, light can enter only from the first opening 120, the amount of entrance is relatively small, when the first light-shielding member 300 is in the closed position shown in fig. 5, most of the light can be shielded, therefore, even if the first light-shielding member 300 is not attached to the inner wall surface and a certain gap exists therebetween, the sensitive device in the detection end 210 is not substantially adversely affected.
It can be understood that the first light-shielding member 300 and the dark room door 700 can be controlled by the controller, that is, the controller controls the first light-shielding member 300 to move from the open position to the closed position before the dark room door 700 needs to be opened; after the darkroom door 700 is completely closed and before detection is needed, the controller controls the first light shielding member 300 to move from the closed position to the open position, so that automatic operation is realized, and errors caused by manual operation are avoided.
Based on the above, the darkroom assembly of the present embodiment utilizes the movable first light-shielding member 300 to open and close the detection channel 130, which does not obstruct the detection of the detection device 200, and can protect the sensitive devices in the detection device 200 when the darkroom door 700 is opened, thereby contributing to prolonging the service life of the detection device 200.
As an improvement to the first embodiment, the darkroom assembly further comprises at least two sensors, wherein the at least two sensors are connected to the darkroom main body 100 along the moving direction of the first light-shielding member 300, and can be triggered by the first light-shielding member 300 moving to different positions, so as to control the position of the first light-shielding member 300. Taking fig. 6 as an example, the darkroom assembly includes two sensors, namely a first sensor 510 and a second sensor 520, the first sensor 510 and the second sensor 520 are both mounted on the darkroom main body 100, specifically, the second housing 180, and the first sensor 510 is located right above the second sensor 520, and the distance between the two sensors is equal to the working stroke of the first light shielding member 300. Referring to fig. 4 and 5, the first light shielding member 300 has a triggering member 340, specifically a triggering sheet connected to the surface of the first light shielding member 300 and extending toward the second housing 180, and the first sensor 510 and the second sensor 520 both use corresponding photoelectric sensors and can be triggered by the passing triggering sheet, specifically, when the triggering sheet triggers the first sensor 510, the first light shielding member 300 moves to the open position shown in fig. 4, and when the triggering sheet triggers the second sensor 520, the first light shielding member 300 moves to the closed position shown in fig. 5, and the position of the first light shielding member 300 can be controlled more accurately through the cooperation of the first sensor 510 and the second sensor 520. It is understood that other types of sensors can be used as the sensor, such as mechanical trigger type, magnetic induction type, etc., and the structure, material, etc. of the trigger 340 can be adjusted according to the type of the sensor.
Generally, the detection portion of the sensor needs to face the cavity 110, and the lead of the sensor needs to be connected to an external power source, so that the installation position of the sensor may have a light leakage problem, and based on this, referring to fig. 7 and 8, the dotted line in the figure indicates the outline of the shielded portion. The darkroom main body 100 has a plurality of through holes 140 and a plurality of first grooves 150 corresponding to the number of the sensors around the wall forming the cavity 110, specifically, two through holes 140 and two first grooves 150 are provided, the through holes 140 penetrate through the second housing 180, and are used for placing the sensors, taking fig. 8 as an example, the through holes 140 are rectangular through holes extending in the left-right direction, it can be understood that the through holes 140 may have other shapes, such as square, circular, and the like, according to the shape of the sensors. The first groove 150 is a routing channel, which is located on the outer surface of the second housing 180 and is communicated with the through hole 140, so that when the sensor is installed in the through hole 140, a wire electrically connected with the sensor can be accommodated in the first groove 150, which is convenient for managing the wire.
In this embodiment, the darkroom main body 100 is further provided with a second groove 160, the second groove 160 is located on the outer surface of the second housing 180, one end of each first groove 150 is communicated with the corresponding through hole 140, and the other end is communicated with the second groove 160, that is, the wires in each first groove 150 can be converged into the second groove 160 and then extend out of the second groove 160, so as to facilitate uniform wire outgoing.
The second groove 160 may have a width equal to that of the first groove 150, and may be machined using the same tool when forming the groove by removing material, for convenience of machining. It will be appreciated that the second groove 160 may also have a different width than the first groove 150, for example wider than the first groove 150, to accommodate convergence of the wires. For similar reasons, the depth of the second groove 160 may be equal to that of the first groove 150, or may be deeper than the first groove 150.
Referring to fig. 7 and 8, the darkroom assembly further includes a second light shielding member 600, the second light shielding member 600 is connected to an outer side of the second housing 180, covers the through holes 140 and the first grooves 150, and extends to at least a portion of the groove segment of the second groove 160, that is, the second light shielding member 600 completely covers the through holes 140 and the first grooves 150, and covers at least a portion of the second groove 160, taking fig. 8 as an example, the second light shielding member 600 covers the first groove segments 161 of the second groove 160 that are communicated with the first grooves 150, the second groove segments 162 of the second groove 160 that are far away from the communication position are exposed outside the second light shielding member 600, and the conductive wires may extend from the second groove segments 162. Based on the above structure, if the external light needs to enter the cavity 110, the external light needs to sequentially pass through the second groove 160, the first groove 150 and the through hole 140, the light path is extended and bent, the light entering the cavity 110 can be effectively reduced, and the dark environment inside the darkroom can be maintained.
The second light-shielding member 600 is attached to the outer surface of the darkroom main body 100 and is locked on the darkroom main body 100 through a plurality of threaded fasteners, specifically, referring to fig. 8, the four corners of the second light-shielding member 600 are all locked through the threaded fasteners, and further, each side of the second light-shielding member 600 can be locked through more than three threaded fasteners, so that the gap between the second light-shielding member 600 and the darkroom main body 100 can be reduced, and the light leakage at the joint of the second light-shielding member 600 and the darkroom main body 100 is reduced.
Referring to fig. 8, each first groove 150 may intersect with the second groove 160, so that light rays need to be bent before entering each first groove 150 from the second groove 160, thereby further ensuring the light shielding effect. Specifically, the two first grooves 150 have the same width, and the central axes thereof are collinear, and can be machined by the same tool. The second grooves 160 are perpendicular to the two first grooves 150, respectively, to form a "T" shape as a whole.
The term "cover" in the above-mentioned scheme may refer to a target area (for example, the through hole 140 and the first groove 150, and the first groove segment 161 of the second groove 160) and a partial area adjacent to the target area, as shown in fig. 8, the first groove 150 is located between the two through holes 140 along the up-down direction, along the left-right direction, and the size of the through hole 140 is larger than that of the first groove 150, so that the second light-shielding member 600 protrudes upward beyond the upper edge of the through hole 140 at the upper end, downward beyond the lower edge of the through hole 140 at the lower end, leftward beyond the left edge of the through hole 140, and rightward beyond the right edge of the through hole 140, thereby reducing light leakage at the joint of the second light-shielding member 600 and the darkroom main body 100. It can be understood that the relative positions of the through hole 140, the first groove 150 and the second groove 160 are not limited to those shown in the drawings, and when other layout patterns are adopted, the shape of the second light shielding member 600 may be adjusted accordingly.
Referring to fig. 9, which shows a schematic diagram of a second embodiment of the present invention, the dotted line in the diagram indicates the outline of the occluded part. The second embodiment differs from the first embodiment in that: in this embodiment, the second groove 160 communicating with each first groove 150 may be omitted, each first groove 150 is not communicated with each other, and the second light shielding member 600 covers the through hole 140 and extends to at least a partial groove section of the first groove 150 communicating with the through hole 140. Specifically, the second light-shielding member 600 completely covers the corresponding through hole 140 and the third groove segment 151 of the first groove 150 communicating with the through hole 140, the fourth groove segment 152 far from the communication position is exposed outside the second light-shielding member 600, and the conductive wire may extend from the fourth groove segment 152.
