Description

Technical Field

[0001] This utility model relates to the field of sensor probes, and more specifically, to a sealed composite sensor probe. Background Technology

[0002] The core component of photoacoustic imaging is the photoacoustic sensor probe, which includes an ultrasonic transducer assembly and an optical component arranged side by side with the ultrasonic transducer assembly. The laser emitted by the optical component illuminates the area below the ultrasonic transducer. To ensure that as much of the area below the ultrasonic transducer as possible is illuminated by the laser emitted by the optical component, a reflector is provided on the optical component.

[0003] A search revealed that Chinese patent CN221750415U discloses a "photoacoustic sensor probe," comprising an ultrasonic transducer assembly, a first optical component arranged side-by-side with the ultrasonic transducer assembly, and a housing that fixes the ultrasonic transducer assembly and the first optical component together. The ultrasonic transducer assembly includes an ultrasonic transducer, and the first optical component includes a first light source, a first lens, and a first reflector. Laser light generated by the first light source is focused by the first lens and then shines onto the first reflector, which deflects the light to illuminate the area directly below the ultrasonic transducer. The position of the first reflector is adjustable to change the distance in the height direction between the laser light reflected by the first reflector and the ultrasonic transducer. However, the following drawbacks still exist:

[0004] (1) The existing sensor probe's sealing structure is an integral part of the sensor. After long-term use, the sealing structure will age, affecting the sealing performance. The sealing structure cannot be replaced separately, which affects the sealing performance in subsequent use.

[0005] (2) Dust will remain on the surface of the existing sealing structure, which cannot be cleaned directly and thoroughly by hand, causing obstruction to the probe and affecting the accuracy of the probe.

[0006] Therefore, we made improvements and proposed a sealed composite sensor probe. Utility Model Content

[0007] The purpose of this invention is to address the current problems of the probe sealing structure not being able to be replaced individually and the surface dust not being able to be thoroughly cleaned.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A sealed composite sensor probe was developed to address the aforementioned issues.

[0010] The present invention is as follows:

[0011] Includes a probe head, a sealing assembly disposed inside the upper side of the probe head, and a cleaning assembly disposed on the upper surface of the probe head;

[0012] The sealing assembly includes a slot opened inside the upper end of the probe, and a sealing plate is detachably inserted into the slot;

[0013] The cleaning component includes sliding grooves on both sides of the upper end of the probe, with a sliding plate movably disposed inside the sliding groove, a connecting plate connecting the two sliding plates, and a brush plate disposed at the lower end of the connecting plate.

[0014] As a preferred technical solution of this utility model, a central groove is provided at the center of the front and rear sides of the sealing plate. A first bevel gear is provided on the inner wall of the upper end of the central groove. A knob is connected to the upper end of the first bevel gear. Twisting the knobs on both sides drives the first bevel gear connected to it to rotate, and meshes with it to drive the second bevel gear to rotate.

[0015] As a preferred technical solution of this utility model, the inner walls on both sides of the central groove are provided with second bevel gears that cooperate with the first bevel gear. When the first bevel gear rotates, the meshing drives the second bevel gear to rotate.

[0016] As a preferred technical solution of this utility model, slots are provided on the outer sides of both ends of the central groove, and a screw is provided inside the slot. A retaining plate is fitted on the outer wall of the screw, and a retaining groove is provided on the side wall of the slot to cooperate with the retaining plate. When the screw rotates, it engages and drives the retaining plate to slide in the slot. With the limiting plate embedded in the limiting groove, the retaining plate is stably inserted into the aligned retaining groove, thus completing the installation of the sealing plate.

[0017] As a preferred technical solution of this utility model, the slotted sidewall is provided with a limiting groove, and the card plate sidewall is provided with a limiting plate that cooperates with the limiting groove. With the limiting plate embedded in the limiting groove, the card plate is stably inserted into the aligned card groove, thus completing the installation of the sealing plate.

[0018] As a preferred technical solution of this utility model, the side wall of the slide groove is provided with a side groove, and the side wall of the slide plate is provided with a side plate that cooperates with the side groove. The side plate slides in the side groove to compress and retract the telescopic rod and the spring, while making the brush plate stick to the surface of the sealing plate to brush away the dust. After brushing, the tension on the connecting plate is released, and the telescopic rod and the spring push the side plate to drive the brush plate to reset so that it can be pulled again to perform the brushing operation.

[0019] As a preferred technical solution of this utility model, a telescopic rod is installed on the side wall of the side groove, and a spring is fitted on the outer wall of the telescopic rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. With the sealing plate, first bevel gear, second bevel gear, clamping plate and limiting plate set up, when it is necessary to seal the opening of the probe, the sealing plate is inserted into the slot, the knobs on both sides are turned to drive the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate, which in turn drives the clamping plate to slide in the slot. With the limiting plate embedded in the limiting slot, the clamping plate is stably inserted into the aligned clamping slot, thus completing the installation of the sealing plate and achieving the sealing of the probe;

[0023] 2. With the help of the sliding plate, brush plate, side plate, telescopic rod, and spring, when it is necessary to clean the dust on the surface of the sealing plate, simply pull the connecting plate and slide it into the sliding groove on both sides. This causes the side plate to slide in the side groove, squeezing and contracting the telescopic rod and spring. At the same time, the brush plate is pressed tightly against the surface of the sealing plate to brush away the dust. After brushing, the tension on the connecting plate is released, and the telescopic rod and spring push the side plate to reset the brush plate, so that it can be pulled again for brushing. This ensures the cleanliness of the probe. Attached Figure Description

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a sealed composite sensor probe, including a probe head 1, a sealing assembly disposed inside the upper side of the probe head 1, and a cleaning assembly disposed on the upper surface of the probe head 1.

[0036] The sealing assembly includes a slot 201 opened inside the upper end of the probe 1, and a sealing plate 202 is detachably inserted into the slot 201;

[0037] The cleaning component includes slide grooves 301 on both sides of the upper end of the probe 1, slide plates 302 are movably arranged inside the slide grooves 301, connecting plates 303 are connected between the two slide plates 302, and brush plates 304 are arranged at the lower end of the connecting plates 303.

[0038] like Figure 2 As shown, a central groove 203 is provided at the center of the front and rear sides of the sealing plate 202. A first bevel gear 204 is provided on the inner wall of the upper end of the central groove 203. A knob 205 is connected to the upper end of the first bevel gear 204. Twisting the knobs 205 on both sides will drive the first bevel gear 204 connected to it to rotate, which will mesh and drive the second bevel gear 206 to rotate, and drive the screw 208 connected to it to rotate.

[0039] like Figure 2 As shown, the inner walls on both sides of the central groove 203 are provided with second bevel gears 206 that cooperate with the first bevel gear 204. When the first bevel gear 204 rotates, it meshes and drives the second bevel gear 206 to rotate, which in turn drives the screw 208 connected to it to rotate. The meshing causes the clamping plate 209 to slide in the slot 207.

[0040] like Figure 2 As shown, slots 207 are provided on the outer sides of both ends of the central groove 203. A screw 208 is provided inside the slot 207. A retaining plate 209 is fitted on the outer wall of the screw 208. A retaining groove 212 is provided on the side wall of the slot 201 to cooperate with the retaining plate 209. When the screw 208 rotates, it engages and drives the retaining plate 209 to slide in the slot 207. Under the limit of the limiting plate 211 embedded in the limiting groove 210, the retaining plate 209 is stably inserted into the aligned retaining groove 212, thus completing the installation of the sealing plate 202.

[0041] like Figure 2 As shown, a limiting groove 210 is provided on the side wall of the slot 207, and a limiting plate 211 is provided on the side wall of the clamping plate 209 to cooperate with the limiting groove 210. Under the limiting of the limiting plate 211 embedded in the limiting groove 210, the clamping plate 209 is stably inserted into the aligned clamping groove 212, thus completing the installation of the sealing plate 202 and realizing the sealing of the probe.

[0042] like Figure 5 As shown, the side wall of the slide 301 is provided with a side groove 305, and the side wall of the slide plate 302 is provided with a side plate 306 that cooperates with the side groove 305. When it is necessary to clean the dust on the surface of the sealing plate 202, the connecting plate 303 is pulled directly and slides in the slide 301 on both sides of the slide plate 302, which drives the side plate 306 to slide in the side groove 305, and compresses and contracts the telescopic rod 307 and the spring 308.

[0043] like Figure 5 As shown, a telescopic rod 307 is installed on the side wall of the side groove 305. A spring 308 is fitted on the outer wall of the telescopic rod 307. When the telescopic rod 307 and the spring 308 are compressed and contracted, the brush plate 304 is pressed tightly against the surface of the sealing plate 202 to brush away the dust. After brushing, the tension on the connecting plate 303 is released, and the telescopic rod 307 and the spring 308 push the side plate 306 to reset the brush plate 304 so that it can be pulled again for brushing.

[0044] Specifically, when using this probe: If sealing of the opening of the probe head 1 is required, insert the sealing plate 202 into the slot 201, turn the knobs 205 on both sides to rotate the first bevel gear 204 connected to it, which in turn rotates the second bevel gear 206, causing the screw 208 connected to it to rotate. This rotation causes the locking plate 209 to slide within the slot 207. With the limiting plate 211 embedded in the limiting groove 210, the locking plate 209 is stably inserted into the aligned locking groove 212, thus completing the installation of the sealing plate 202 and achieving… The probe is sealed. When it is necessary to clean the dust on the surface of the sealing plate 202, the connecting plate 303 is pulled directly and slides in the sliding groove 301 on both sides of the sliding plate 302. This causes the side plate 306 to slide in the side groove 305, which compresses and contracts the telescopic rod 307 and the spring 308. At the same time, the brush plate 304 is pressed against the surface of the sealing plate 202 to brush away the dust. After brushing, the pulling force on the connecting plate 303 is released, and the telescopic rod 307 and the spring 308 push the side plate 306 to reset the brush plate 304 so that it can be pulled again for brushing. This ensures the cleanliness of the probe.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
