Description

Technical Field

[0001] This application relates to the technical field of X-ray devices, and particularly to a portable X-ray device. Background Art

[0002] X-ray tubes are commonly used in industrial diagnostic systems, medical diagnostic systems, etc., such as for X-ray foreign object inspection and X-ray analysis carried out in industrial fields, etc. X-ray analysis is the component analysis of various materials and the composition analysis of products; currently, X-ray tubes on the market are divided into desktop and handheld types. Desktop X-ray devices cannot be moved and can only be used in a fixed position, while handheld X-ray tube devices can move freely and can switch different application scenarios according to different needs, greatly improving their usability, so they are widely used.

[0003] A portable X-ray device usually includes a detection host and a detection head installed on the detection host. When X-ray detection is required, the detection host is moved to a suitable position, and the detection position of the detection head is adjusted so that the detection head is aligned with the detection point; during the operation of the detection host, after the cathode filament in the detection host is installed with a heating power supply, active electrons are generated. A voltage difference is applied between the anode and the cathode to attract the electrons to collide with the anode at high speed, and then energy conversion occurs. When the electrons are blocked during movement and lose their kinetic energy, part of the energy can be converted into effective X-rays, so as to carry out operations such as X-ray foreign object inspection and X-ray analysis; among them, during the process of the electrons colliding with the anode at high speed, a large amount of heat can be generated. To timely discharge this part of the heat, a cooling fan is usually installed in the detection host, and the cooling fan blows air into the detection host, so as to accelerate the discharge of the heat in the detection host and reduce the possibility of damage to its components caused by too high internal temperature of the detection host.

[0004] Existing portable X-ray devices usually install a dust-proof net at the air inlet of the detection host to block the dust in the air; however, when the X-ray device is in a scene with a large amount of dust, during the process of the cooling fan blowing air into the detection host, the dust-proof net can intercept large particles of dust in the air, while small particles of dust in the air are still likely to enter the detection host through the gaps of the dust-proof net, thus causing pollution to the internal components of the detection host, so further improvement is needed. Summary of the Invention

[0005] In order to reduce the possibility of external dust entering the detection host and polluting the internal components of the detection host, this application provides a portable X-ray device.

[0006] The portable X-ray device provided by this application adopts the following technical solutions:

[0007] A portable X-ray device includes a detection host. An installation chamber is provided inside the detection host, and a detection module for X-ray detection is installed in the installation chamber. A detection head is installed on one side of the detection host. The detection head penetrates the side wall of the detection host and is electrically connected to the detection module. A air supply chamber is provided inside the detection host, and an air duct communicating with the installation chamber is opened on the side wall of the air supply chamber. An air supply groove is opened on the side wall of the detection host adjacent to the detection head. The air supply groove is a through groove penetrating the two opposite side walls of the detection host. A first communication groove communicating with the air supply chamber is opened on the side wall of the air supply groove. Cooling fans for blowing air into the air supply groove are provided at both ends of the air supply groove. A rotating shaft is rotatably installed in the first communication groove. A partition sheet is fixed on the outer peripheral wall of the rotating shaft. The partition sheet is spirally arranged along the length direction of the rotating shaft, and the outer peripheral wall of the partition sheet fits the inner peripheral wall of the first communication groove. A plurality of ventilation holes penetrating the partition sheet are opened on the partition sheet. A rotating member for driving the rotating shaft to rotate is installed on the rotating shaft.

[0008] By adopting the above technical solution, through the arrangement of the rotating shaft and the partition sheet, when cooling the detection host, the cooling fans at both ends of the air supply groove are started to blow air into the air supply groove. The air flow enters the air supply chamber through the first communication groove and flows into the installation chamber through the air duct to take away the heat generated by the detection module. By respectively arranging cooling fans at both ends of the air supply groove, the two cooling fans blow air into the air supply groove at the same time, which can further improve the heat dissipation effect of the installation chamber and reduce the possibility of damage to its components caused by too high internal temperature of the detection host. When the air flow passes through the partition sheet in the first communication groove, the air flow can enter the air supply cavity through the ventilation holes of the partition sheet. Large-particle dust in the air flow can be blocked on the surface of the partition sheet, thereby reducing the possibility of dust entering the installation cavity. During the process of the air flow passing through the first communication groove, the rotating member drives the rotating shaft and the partition sheet to rotate, and forces the conveying direction of the partition sheet to be opposite to the flow direction of the air flow. The partition sheet can play the role of slowing down the air flow velocity and the dust flow velocity in the air flow. The rotating partition sheet has an active fishing effect on small-particle dust in the air, so that the small-particle dust in the air flow can be caught by the partition sheet and deposited on the surface of the partition sheet, reducing the possibility of dust entering the installation cavity, and further reducing the possibility of the components of the detection module in the installation cavity being contaminated by dust.

[0009] Optionally, a second communication groove communicating with the air supply chamber is formed in the side wall of the air supply groove. A blocking plate is slidably installed near the notch of the air supply groove. The blocking plate is normally located at the notch of the second communication groove and closes the second communication groove. The blocking plate is provided with a sliding assembly for driving the blocking plate to slide between the first communication groove and the second communication groove. When the sliding assembly forces the blocking plate to move to the notch of the first communication groove, the blocking plate opens the second communication groove and closes the first communication groove. A collection groove for collecting dust is provided on the side wall of the blocking plate close to the first communication groove.

[0010] By adopting the above technical solution, through the arrangement of the second communication groove and the blocking plate, when a certain amount of dust accumulates on the surface of the partition piece, the sliding assembly forces the blocking plate to move to the notch of the first communication groove and close the first communication groove, so as to open the second communication groove. Then, the cooling fan is started to blow air. The air flow can enter the air supply chamber through the second communication groove and enter the first communication groove through the air supply chamber. After passing through the partition piece, the air flow can blow the dust on the surface of the partition piece towards the collection groove, so as to collect the dust in the collection groove and reduce the possibility of the ventilation holes being blocked due to excessive dust on the surface of the partition piece.

[0011] Optionally, a sliding groove communicating with the air supply groove is formed in the side wall of the detection host adjacent to the cooling fan. The blocking plate is slidably installed in the sliding groove. A discharge groove communicating with the collection groove is formed in the side wall of the blocking plate close to the notch of the sliding groove. A sliding groove is formed at the notch of the sliding groove. The sliding assembly includes a sliding plate and a rotating rod. The sliding plate is slidably installed in the sliding groove. A discharge port penetrating through the sliding plate is formed on the plate surface of the sliding plate close to the sliding groove. When the blocking plate closes the second communication groove, the sliding plate closes the discharge groove. One end of the rotating rod is hinged to the side wall of the sliding plate close to the blocking plate, and the other end is hinged to the side wall of the blocking plate. When the blocking plate closes the first communication groove, the sliding plate slides and forces the discharge port to be aligned with the discharge groove.

[0012] By adopting the above technical solution, through the arrangement of the sliding plate and the rotating rod, the blocking plate is normally closed in the second communication groove. At this time, the sliding plate blocks the discharge groove, and the air flow can flow through the first communication groove to the air supply chamber for cooling the detection module; when it is necessary to clean the dust on the surface of the partition piece, the sliding plate is pulled to force the sliding plate to slide in the sliding groove. Under the action of the rotating rod, the sliding plate drives the blocking plate to slide in the sliding groove. When the blocking plate slides and blocks the first communication groove, the discharge port of the sliding plate is facing the discharge groove at this time, so as to open the discharge groove, and then connect the discharge groove to the outside of the detection host. The cooling fan is started to blow air into the second communication groove. The air flow enters the first communication groove through the air supply chamber and blows the dust to the collection groove, and is discharged outwards through the discharge groove and the discharge port, improving the convenience of cleaning the dust and reducing the possibility of blockage due to excessive dust accumulation on the partition piece.

[0013] Optionally, the discharge groove is gradually flared from the side away from the collection groove to the side close to the collection groove.

[0014] By adopting the above technical solution, the discharge groove is flared, so that the dust collected in the collection groove can enter the discharge groove and be discharged outwards through the discharge groove.

[0015] Optionally, the side walls of the sliding plate are respectively provided with a first positioning hole and a second positioning hole arranged at intervals. A positioning post for inserting into the first positioning hole or the second positioning hole is slidably installed on the side wall of the sliding groove close to the first positioning hole; when the positioning post is inserted into the first positioning hole, the sliding plate is closed to the discharge groove, and when the positioning post is inserted into the second positioning hole, the discharge port is facing the discharge groove. The positioning post is provided with a moving component for driving the positioning post to approach or move away from the sliding plate.

[0016] By adopting the above technical solution, through the arrangement of the first positioning hole and the second positioning hole, the sliding plate is pulled to force the first positioning hole or the second positioning hole to move to a state opposite to the positioning post, and then the positioning post is forced to be inserted into the first positioning hole or the second positioning hole through the moving component, so as to force the sliding plate to maintain the state of being open to the discharge groove or the state of being closed to the discharge groove, and then force the blocking plate to block the first communication groove or the second communication groove. When the sliding plate is driven to slide and the positioning post is forced to be inserted into the second positioning hole, the discharge port of the sliding plate can face the discharge groove, so that the dust in the collection groove can be discharged outwards through the discharge groove. The positioning post inserted into the second positioning hole can play a role in fixing the sliding plate and reduce the possibility that the sliding plate freely slides and blocks the discharge groove, resulting in the dust not being discharged outwards.

[0017] Optionally, a positioning groove is formed in the side wall of the sliding groove close to the first positioning hole. The moving assembly includes a moving block slidably installed in the positioning groove and a first compression spring installed between the positioning groove and the moving block. The positioning post is fixed to the side wall of the moving block close to the sliding plate. One side of the moving block penetrates through the side wall of the positioning groove and extends to the outside of the detection host. The first compression spring normally forces the moving block to move to the notch of the positioning groove.

[0018] By adopting the above technical solution, through the arrangement of the moving block and the first compression spring, when it is necessary to slide the sliding plate, press the moving block and force the positioning post to move into the positioning groove, so as to force the positioning post to disengage from the first positioning hole or the second positioning hole, so that the sliding plate can slide along the sliding groove, and control the baffle to close the first communication groove or the second communication groove, improving the operation convenience of the baffle closing the first communication groove or the second communication groove.

[0019] Optionally, when the positioning post is inserted into the first positioning hole, the sliding plate slides and abuts against one side wall of the sliding groove. When the positioning post is inserted into the second positioning hole, the sliding plate slides and abuts against the other side wall of the sliding groove.

[0020] By adopting the above technical solution, pull the sliding plate to slide in the sliding groove. When the sliding plate moves and abuts against the side walls of the two ends of the sliding groove, the positioning post can be aligned with the first positioning hole or the second positioning hole, so that the positioning post can be quickly aligned and inserted into the first positioning hole or the second positioning hole, improving the operation convenience of the overall structure.

[0021] Optionally, a scraping strip is slidably installed on the outer peripheral wall of one end of the rotating shaft close to the air supply groove. The scraping strip is normally located in the first communication groove. The scraping strip is provided with a sliding assembly for driving the scraping strip to slide along the length direction of the rotating shaft. When the baffle closes the first communication groove, the sliding assembly forces the scraping strip to move into the collection groove.

[0022] By adopting the above technical solution, through the arrangement of the scraping strip, when the baffle closes the first communication groove and the dust raised by the partition sheet blows towards the collection groove, the sliding assembly drives the scraping strip to move into the collection groove, and then drives the rotating shaft to rotate. The rotating shaft can drive the scraping strip to rotate, and the rotating scraping strip can scrape the dust deposited on the side wall of the collection groove, so that the dust can be discharged outwards through the discharge groove.

[0023] Optionally, a sliding sleeve is slidably mounted on the outer peripheral wall of the rotating shaft, the scraping strip is fixed to the outer peripheral wall of the sliding sleeve, the scraping strip is slidably mounted on the rotating shaft through the sliding sleeve, a moving groove is formed in the side wall of the air supply groove, and the moving groove communicates with the first communication groove; the sliding assembly includes a rotating sleeve, a pushing block and a second compression spring, the rotating sleeve is rotatably mounted on the outer peripheral wall of the sliding sleeve, the pushing block is slidably mounted in the moving groove, the side wall of the pushing block away from the air supply groove is fixedly connected to the rotating sleeve, the compression spring is mounted between the moving groove and the pushing block, and in the normal state of the compression spring, the pushing block is partially exposed out of the moving groove and forces the scraping strip to move to the collection groove, and the side wall of the pushing block close to the air supply groove has a guiding surface. When the blocking plate moves towards the second communication groove, the blocking plate forces the pushing block to move into the moving groove and forces the scraping strip to move into the first communication groove.

[0024] By adopting the above technical solution, through the arrangement of the rotating sleeve, the pushing block and the second compression spring, when the blocking plate moves to the notch of the second communication groove, the blocking plate can push the pushing block to move into the moving groove and force the scraping strip to move into the first communication groove. At this time, the pushing block squeezes the second compression spring and forces the second compression spring to store elastic force. When the blocking plate moves to the first communication groove, the blocking plate disengages from the pushing effect on the pushing block, and the compression spring can drive the pushing block to be partially exposed out of the moving groove, thereby driving the rotating sleeve and the sliding sleeve to move towards the side close to the blocking plate, and further forcing the scraping strip to move into the collection groove. When the rotating shaft drives the scraping strip to rotate, the scraping strip can scrape the dust in the collection groove, causing the dust to rise and be discharged outwards through the discharge groove, improving the discharge efficiency of the dust.

[0025] Optionally, a plurality of air ducts are provided and are evenly distributed along the side wall of the air supply chamber close to the installation chamber, and each air duct communicates with the installation chamber.

[0026] By adopting the above technical solution, by providing multiple air ducts, the speed of the air flow entering the installation chamber can be increased, thereby improving the efficiency of the air flow taking away the heat in the installation chamber and reducing the possibility of damage to the detection module caused by excessive temperature in the installation chamber.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. With the setting of the rotating shaft and the partition plate, when cooling the detection host, start the cooling fans at both ends of the air supply trough to blow air into the air supply trough. The air flow enters the air supply chamber through the first communication trough and flows through the air duct into the installation chamber to take away the heat generated by the detection module. By setting cooling fans at both ends of the air supply trough, the two cooling fans blow air into the air supply trough at the same time, which can further improve the heat dissipation effect of the installation chamber and reduce the possibility of damage to its components caused by overheating inside the detection host. When the air flow passes through the partition plate of the first communication trough, the air flow can enter the air supply cavity through the ventilation holes of the partition plate, and large-particle dust in the air flow can be blocked on the surface of the partition plate, thereby reducing the possibility of dust entering the installation cavity. During the process of the air flow passing through the first communication trough, the rotating shaft and the partition plate are driven to rotate by the rotating part, and the conveying direction of the partition plate is forced to be opposite to the flow direction of the air flow. The partition plate can slow down the air flow velocity and the dust flow velocity in the air flow. The rotating partition plate has an active fishing effect on small-particle dust in the air, so that the small-particle dust in the air flow can be caught by the partition plate and deposited on the surface of the partition plate, reducing the possibility of dust entering the installation cavity, and further reducing the possibility of the components of the detection module in the installation cavity being polluted by dust;

[0029] 2. With the setting of the second communication trough and the blocking plate, when a certain amount of dust accumulates on the surface of the partition plate, the blocking plate is forced to move to the notch of the first communication trough and close the first communication trough through the sliding component, thereby opening the second communication trough. Then start the cooling fan to blow air. The air flow can enter the air supply chamber through the second communication trough and enter the first communication trough through the air supply chamber. After passing through the partition plate, the air flow can blow the dust on the surface of the partition plate into the collection trough, thereby collecting the dust in the collection trough and reducing the possibility of blockage of the ventilation holes caused by excessive dust on the surface of the partition plate;

[0030] 3. With the setting of the rotating sleeve, the push block and the second compression spring, when the blocking plate moves to the notch of the second communication trough, the blocking plate can push the push block to move into the moving groove and force the scraping strip to move into the first communication trough. At this time, the push block compresses the second compression spring and forces the second compression spring to have elastic force. When the blocking plate moves to the first communication trough, the blocking plate disengages from the pushing effect on the push block. The compression spring can drive the push block to be partially exposed outside the moving groove, thereby driving the rotating sleeve and the sliding sleeve to move towards the side close to the blocking plate, and further forcing the scraping strip to move into the collection trough. When the rotating shaft drives the scraping strip to rotate, the scraping strip can scrape the dust in the collection trough, causing the dust to rise and be discharged outwards through the discharge trough, improving the discharge efficiency of the dust.

In this embodiment, the air supply chamber 14 is arranged on the side of the installation chamber 11 away from the detection head 13. A plurality of air ducts 141 are opened on the side wall of the air supply chamber 14 close to the installation chamber 11. Each air duct 141 communicates with the installation chamber 11, and all the air ducts 141 are evenly distributed along the side wall of the air supply chamber 14 close to the installation chamber 11; A plurality of first heat dissipation holes 111 are opened on two opposite side walls of the detection host 1 adjacent to the detection head 13, and all the first heat dissipation holes 111 communicate with the installation chamber 11.

[0045] Refer to Figure 1 , Figure 2 , a air supply groove 15 is opened on the side wall of the detection host 1 adjacent to the detection head 13. In this embodiment, the air supply groove 15 is a through groove penetrating two opposite side walls of the detection host 1. The air supply groove 15 is located between the installation chamber 11 and the air supply chamber 14; A first communication groove 151 communicating with the air supply chamber 14 is opened on the side wall of the air supply groove 15 close to the air supply chamber 14. Installation grooves 154 are opened at both ends of the air supply groove 15.

One end of the rotating shaft 3 is rotatably connected to the side wall of the detection host 1 away from the detection head 13, and the other end passes through the air supply chamber 14 and extends into the first communication groove 151. The central axis of the rotating shaft 3 coincides with the central axis of the first communication groove 151; a partition piece 31 located in the first communication groove 151 is fixedly installed on the outer peripheral wall of the rotating shaft 3. In this embodiment, the partition piece 31 is spirally arranged along the length direction of the rotating shaft 3, the outer peripheral wall of the partition piece 31 is attached to the inner peripheral wall of the first communication groove 151, and a plurality of ventilation holes 311 penetrating through the partition piece 31 are formed in the plate surface of the partition piece 31, and all the ventilation holes 311 are evenly distributed along the plate surface of the partition piece 31; the detection host 1 is equipped with a rotating member for driving the rotating shaft 3 to rotate.

[0048] With such a design, by driving the partition piece 31 to rotate through the rotating member, when the cooling fan 2 blows air into the first communication groove 151, the air flow can enter the air supply chamber 14 through the ventilation holes 311 to take away the heat in the installation chamber 11; the dust in the air flow is blocked on the surface of the partition piece 31, and the rotating partition piece 31 can actively capture the dust in the air flow, reducing the possibility of the dust in the air flow entering the air supply chamber 14, thereby reducing the possibility of the dust entering the installation chamber 11 through the air supply chamber 14 and polluting the components in the installation chamber 11.

[0049] Refer to Figure 3 , Figure 4 , in this embodiment, the rotating member is set as a rotating motor 34. The rotating motor 34 is fixedly installed on the side wall of the detection host 1 away from the detection head 13, and the output shaft of the rotating motor 34 is coaxially connected to the rotating shaft 3; starting the rotating motor 34 to drive the rotating shaft 3 to rotate can drive the partition piece 31 to rotate around the central axis of the rotating shaft 3.

The side wall of the blocking plate 4 close to the air supply chamber 14 fits against the side wall of the air supply groove 15 close to the air supply chamber 14. When the blocking plate 4 moves to the notch of the first communication groove 151 close to the air supply groove 15, the blocking plate 4 closes the first communication groove 151 and opens the second communication groove 152. An extension part 43 is integrally arranged on one side of the blocking plate 4. When the blocking plate 4 drives the extension part 43 to move to the notch of the second communication groove 152, the extension part 43 of the blocking plate 4 closes the second communication groove 152 and the blocking plate 4 opens the first communication groove 151.

[0052] Refer to Figure 3 , Figure 5 , a collection groove 41 for collecting dust is formed in the side wall of the blocking plate 4 close to the first communication groove 151. When the blocking plate 4 moves to the notch of the first communication groove 151, the collection groove 41 faces the first communication groove 151. An exhaust groove 42 communicating with the collection groove 41 is formed in the side wall of the blocking plate 4 close to the notch of the sliding groove 16; in this embodiment, the exhaust groove 42 is gradually flared from the side far away from the collection groove 41 to the side close to the collection groove 41; a sliding assembly 5 for driving the blocking plate 4 to slide between the first communication groove 151 and the second communication groove 152 is installed on the blocking plate 4; designed in this way, when blowing air to dissipate heat from the installation chamber 11, the extension part 43 of the blocking plate 4 is driven by the sliding assembly 5 to move to the notch of the second communication groove 152, so as to close the second communication groove 152; then the cooling fan 2 is started to blow air into the air supply groove 15, and the air flow can enter the air supply chamber 14 through the first communication groove 151 to dissipate heat and cool down the installation chamber 11; when a certain amount of dust adheres to the surface of the partition piece 31, the blocking plate 4 is forced to move to the notch of the first communication groove 151 by the sliding assembly 5, so as to close the first communication groove 151 and open the second communication groove 152. At this time, the air flow in the air supply groove 15 can sequentially pass through the second communication groove 152, the air supply chamber 14 and enter the first communication groove 151, so as to blow the dust adhering to the surface of the partition piece 31 into the collection groove 41 and discharge it outwards through the exhaust groove 42, reducing the possibility of excessive dust accumulation and blockage on the surface of the partition piece 31.

The sliding plate 51 is slidably installed in the sliding groove 17. An exhaust port 511 penetrating the sliding plate 51 is formed in the plate surface of the sliding plate 51 close to the sliding groove 16. A handle 514 for driving the sliding plate 51 to slide along the sliding groove 17 is fixedly installed on the plate surface of the sliding plate 51 far from the sliding groove 16.

[0054] Referring to Figure 3 , Figure 4 , the rotating rod 52 is installed in the avoidance groove 173. One end of the rotating rod 52 is hinged to the side wall of the sliding plate 51 close to the blocking plate 4, and the other end is hinged to the side wall of the blocking plate 4 far from the collecting groove 41. When the extending portion 43 of the blocking plate 4 is closed to the second communication groove 152, the sliding plate 51 blocks the notch of the sliding groove 16 and is closed to the notch of the discharge groove 42 far from the collecting groove 41. When the blocking plate 4 is closed to the first communication groove 151, the discharge port 511 of the sliding plate 51 is facing the notch of the discharge groove 42 far from the collecting groove 41; designed in this way, pulling the sliding plate 51 forces the sliding plate 51 to slide in the sliding groove 17 and forces the discharge port 511 to face the notch of the discharge groove 42. The blocking plate 4 can move to the notch of the first communication groove 151 and open to the second communication groove 152 under the drive of the rotating rod 52. The air flow blown out by the cooling fan 2 can blow the dust on the surface of the partition piece 31 towards the collecting groove 41 and discharge it outwards through the discharge groove 42 and the discharge port 511 in sequence, improving the convenience of cleaning the dust on the surface of the partition piece 31.

[0055] Referring to Figure 1 , Figure 6 , first positioning holes 512 and second positioning holes 513 are respectively formed in the side walls of the sliding plate 51. In this embodiment, the first positioning holes 512 and the second positioning holes 513 are arranged at intervals along the sliding direction of the sliding plate 51; a positioning groove 172 is formed in the side wall of the sliding groove 17 close to the first positioning hole 512. A positioning column 171 is slidably installed in the positioning groove 172, and a moving assembly 6 for driving the positioning column 171 to be inserted into the first positioning hole 512 or the second positioning hole 513 is installed in the positioning groove 172; when the moving assembly 6 forces the positioning column 171 to be inserted into the first positioning hole 512, the sliding plate 51 is closed to the discharge groove 42 and forces the blocking plate 4 to be closed to the second communication groove 152. When the positioning column 171 is inserted into the second positioning hole 513, the discharge port 511 of the sliding plate 51 is facing the discharge groove 42; designed in this way, by inserting the positioning column 171 into the first positioning hole 512 or the second positioning hole 513, the blocking plate 4 can be forced to be closed to the second communication groove 152 or the first communication groove 151, facilitating the operator to switch the opening and closing between the first communication groove 151 and the second communication groove 152.

[0056] Reference Figure 1 and Figure 6 , the moving component 6 includes a moving block 61 and a first compression spring 62. The moving block 61 is slidably installed in the positioning groove 172. One side of the moving block 61 penetrates through the side wall of the positioning groove 172 and extends to the outside of the detection host 1. The positioning post 171 is fixedly installed on the side wall close to the sliding plate 51. The first compression spring 62 is installed in the positioning groove 172. One end of the first compression spring 62 is fixedly connected to the bottom of the positioning groove 172, and the other end is fixedly connected to the moving block 61. In the normal state, the first compression spring 62 moves the moving block 61 close to the side wall of the sliding plate 51 to the notch of the positioning groove 172. With such a design, when it is necessary to switch the opening and closing between the first communication groove 151 and the second communication groove 152, by pressing the moving block 61, the positioning post 171 can be forced to move towards the side close to the positioning groove 172 and disengage from the first positioning hole 512 or the second positioning hole 513, so that the sliding plate 51 can slide in the sliding groove 17. When the sliding plate 51 slides and forces the first positioning hole 512 or the second positioning hole 513 to move opposite to the positioning post 171, release the moving block 61, and the elastic force of the first compression spring 62 can force the positioning post 171 to be inserted into the first positioning hole 512 or the second positioning hole 513, so that the blocking plate 4 can switch the opening and closing between the first communication groove 151 and the second communication groove 152.

[0057] Reference Figure 3 and Figure 4 , in this embodiment, when the positioning post 171 is inserted into the second positioning hole 513 to force the discharge port 511 to be directly opposite to the discharge groove 42, one side wall of the sliding plate 51 abuts against one side wall of the sliding groove 17. When the positioning hole is inserted into the first positioning hole 512, the sliding plate 51 abuts against the other side wall of the sliding groove 17. With such a design, the operator pulls the sliding plate 51 to force the side wall of the sliding plate 51 to abut against the side wall of the sliding groove 17, so that the positioning post 171 can be quickly aligned with the first positioning hole 512 or the second positioning hole 513, and further enable the blocking plate 4 to quickly switch between the second communication groove 152 and the first communication groove 151, improving the operation convenience of the overall structure.

[0058] The implementation principle of Embodiment 1 of this application is as follows: During the process of the cooling fan 2 blowing air into the air supply trough 15, the air flow can enter the air supply chamber 14 through the first communication trough 151 and flow to the installation chamber 11 through the air duct 141, so as to accelerate the heat emission speed in the installation chamber 11 and reduce the possibility of damage to the detection module 12 caused by excessive temperature in the installation chamber 11; when the air flow passes through the first communication trough 151, the dust in the air flow can adhere to the surface of the partition piece 31 under the blockage of the partition piece 31, reducing the possibility of dust entering the installation chamber 11 and polluting the detection module 12; on the other hand, when the air flow passes through the first communication trough 151, the rotation motor 34 is started to drive the partition piece 31 to rotate and force the conveying direction of the partition piece 31 to be opposite to the flow direction of the air flow. The partition piece 31 can play the role of slowing down the air flow velocity and the dust flow velocity. At the same time, the rotating partition piece 31 can actively capture the dust in the air flow, so that the small-particle dust in the air flow can be captured on the surface of the partition piece 31, further reducing the possibility of the dust in the air flow entering the installation chamber 11.

[0059] Embodiment 2:

[0060] This application embodiment discloses a portable X-ray device.

[0061] Referring to Figure 7 、 Figure 8 The difference between the portable X-ray device disclosed in this application embodiment and Embodiment 1 is that:

[0062] A sliding sleeve 33 is slidably installed on the outer peripheral wall of one end of the rotating shaft 3 close to the air supply trough 15. An anti-disengagement block 35 for blocking the sliding sleeve 33 is fixedly installed on the end face of the rotating shaft 3 close to the air supply trough 15. A plurality of scraping strips 32 are fixedly installed on the outer peripheral wall of the sliding sleeve 33. All the scraping strips 32 are arranged at intervals around the outer peripheral wall of the sliding sleeve 33; the sliding sleeve 33 is equipped with a sliding assembly 7 for driving the sliding sleeve 33 to slide along the length direction of the rotating shaft 3; when the blocking plate 4 moves to the notch of the second communication trough 152, the sliding assembly 7 forces the scraping strips 32 and the sliding sleeve 33 to move into the first communication trough 151, and when the blocking plate 4 moves to the notch of the first communication trough 151, the sliding assembly 7 forces the scraping strips 32 and the sliding sleeve 33 to move into the collection trough 41.

[0063] Referring to Figure 7 、 Figure 8, a moving groove 153 is formed in the side wall of the air supply groove 15 close to the air supply chamber 14. The moving groove 153 is located between the first communication groove 151 and the second communication groove 152, and the moving groove 153 communicates with the first communication groove 151. The sliding component 7 includes a rotating sleeve 71, a pushing block 72 and a second compression spring 73. The rotating sleeve 71 is rotatably installed on the outer peripheral wall of the sliding sleeve 33. The pushing block 72 is slidably installed in the moving groove 153. A connecting rod 711 is connected between the pushing block 72 and the rotating sleeve 71. One end of the connecting rod 711 is fixedly installed on the pushing block 72, and the other end is fixedly connected to the outer peripheral wall of the rotating sleeve 71.

[0064] Referring to Figure 7 , the second compression spring 73 is installed in the moving groove 153. One end of the second compression spring 73 is fixedly connected to the bottom of the moving groove 153, and the other end is fixedly connected to the moving block 61. In the normal state of the second compression spring 73, the pushing block 72 is partially exposed from the moving groove 153; the side wall of the pushing block 72 close to the air supply groove 15 has a guiding surface. When the blocking plate 4 moves towards the second communication groove 152, the blocking plate 4 forces the pushing block 72 to move into the moving groove 153 and forces the scraping strip 32 to move into the first communication groove 151. When the blocking plate 4 closes the second communication groove 152, the plate surface of the blocking plate 4 close to the air supply chamber 14 closes the notch of the moving groove 153.

[0065] With such a design, when the blocking plate 4 closes the second communication groove 152, at this time, the blocking plate 4 can abut against the guiding surface of the moving block 61 and force the scraping strip 32 and the sliding sleeve 33 to move into the first communication groove 151, reducing the possibility that when the blocking plate 4 moves towards the side close to the first communication groove 151, the scraping strip 32 blocks the blocking plate 4 and the blocking plate 4 cannot close the first communication groove 151; after the blocking plate 4 closes the first communication groove 151, the blocking plate 4 is separated from the blocking effect on the moving groove 153, and the moving block 61 can be partially exposed from the moving groove 153 under the action of the second compression spring 73, so as to force the scraping strip 32 to move into the collection groove 41, and then drive the rotating shaft 3 to rotate, so that the scraping strip 32 can scrape the dust on the side wall of the collection groove 41, so that the dust in the collection groove 41 can quickly be discharged outwards through the discharge groove 42.

[0066] Referring to Figure 7 、 Figure 8, there is a gap between the side wall of the scraping strip 32 away from the sliding sleeve 33 and the side wall of the collection groove 41, and the gap between the side wall of the scraping strip 32 away from the sliding sleeve 33 and the side wall of the collection groove 41 is not less than the depth of the collection groove 41; with such a design, when the blocking plate 4 moves towards the side close to the second communication groove 152, the extending portion 43 of the blocking plate 4 can abut against the guiding surface of the moving block 61 and force the scraping strip 32 to move into the first moving groove 153. The gap between the side wall of the scraping strip 32 away from the sliding sleeve 33 and the side wall of the collection groove 41 can provide an avoidance space, reducing the possibility that the scraping strip 32 collides with the side wall of the collection groove 41 during the movement of the blocking plate 4.

[0067] The implementation principle of Embodiment 2 of this application is as follows: when the blocking plate 4 moves towards the side close to the second communication groove 152, the extending portion 43 of the blocking plate 4 can abut against the guiding surface of the moving block 61 and force the scraping strip 32 to move into the first moving groove 153, thereby forcing the second compression spring 73 to store elastic force; when the blocking plate 4 moves to the notch of the first communication groove 151 and loses the blocking effect on the moving groove 153, the pushing block 72 can partially move out of the moving groove 153 under the action of the second compression spring 73 and force the scraping strip 32 to move into the collection groove 41. By rotating the rotating shaft 3, the scraping strip 32 can be driven to rotate and scrape the dust on the side wall of the collection groove 41, so that the dust in the collection groove 41 can quickly be discharged outwards through the discharge groove 42, reducing the possibility that the dust adheres to the side wall of the collection groove 41 and cannot be blown outwards.

[0068] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
