Example 1
Please refer to fig. 1-7.
A sampling device 100 comprises a sampling mechanism 12 for connecting an external sampler 40, a positioning module 20 for acquiring position information of a sample, and a driving mechanism 30 for receiving the position information and driving the sampling mechanism 12 to rotate towards the position of the sample according to the position information.
The sampling mechanism 12 may be connected to the external sampler 40 and drive the sampler 40 to move, and specifically, the external sampler 40 may be composed of two parts. For example, a two-section sampling tube has one end provided with a protective housing and the other end provided with a sampling end, and is fixedly arranged at one end serving as the protective housing, and one end serving as a sampling end 42 is connected with the sampling mechanism 12 for the sampling mechanism 12 to pull out.
The positioning module 20 scans and positions excrement in the toilet and transmits scanned position information to the driving mechanism 30. Specifically, the positioning module 20 may be an infrared scanning module or a visual scanning module, which mainly recognizes the kind of excrement (such as feces or urine) in the toilet, recognizes the position of the excrement, generates position information indicating the position of the excrement, and transmits the position information to the driving mechanism 30.
The driving mechanism 30 drives the sampling mechanism 12 and the sampler 40 connected with the sampling mechanism 12 to rotate towards the position of the excrement sample according to the position information sent by the positioning module 20, so that the sampling mechanism 12 finishes collecting the excrement sample. It will be appreciated that the driving mechanism 30 may drive the sampling mechanism 12 to rotate, that is, the driving mechanism 30 is connected to the end of the sampling mechanism 12 and uses the end of the sampling mechanism 12 as a fixed position, and drives the front end of the sampling mechanism 12 (i.e. the end connected with the sampler) to rotate towards the position of the sample, so that the driving mechanism 30 may indirectly drive the external sampler 40 to sample the excrement sample. Therefore, the sampling device 100 of the present embodiment does not require a person to sample the excrement sample by hands, so that the sampling of the sample is more automated, intelligent, sanitary and convenient.
In this embodiment, the sampling apparatus 100 further includes a stabilizing mechanism 11, where the stabilizing mechanism 11 is connected to the fixed end 41 of the sampler 40, the sampling mechanism 12 is connected to the sampling end 42 of the sampler 40, the stabilizing mechanism 11 and the sampling mechanism 12 separate the fixed end 41 from the sampling end 42, and the sampling mechanism 12 is connected to the driving mechanism 30.
On the basis of the above structure, a sampling apparatus 100 may further include a fixing mechanism 11, and the fixing mechanism 11 is connected to the fixed end 41 of the sampler 40.
In a specific embodiment, the securing mechanism 11 may include a snap ring, a catch, or the like to secure the fixed end 41 of the sampler 40. The sampling mechanism 12 is connected with the sampling end 42 of the sampler 40, and the sampling mechanism 12 drives the sampling end 42 to move so as to pull out the sampling end 42 from the connection part of the fixed end 41.
For example, in the above process, the fixing mechanism 11 fixes the fixing end 41 of the sampler 40, and the sampling mechanism 12 moves and drives the sampling end 42 to move, so that the sampling end 42 is separated from the connection with the fixing end 41. The driving mechanism 30 is connected with the sampling mechanism 12, and drives the sampling mechanism 12 to drive the sampling end 42 to move towards the excrement.
In another specific embodiment, the securing mechanism 11 may include a snap ring, a catch, or the like to secure the fixed end 41 of the sampler 40. The sampling mechanism 12 is fixedly connected with the sampling end 42 of the sampler 40, the fixing mechanism 11 drives the fixing end 41 to move, and the fixing end 41 is pulled out of the connection position of the sampling end 42.
For example, in the above process, the sampling mechanism 12 fixes the sampling end 42 of the sampler 40, and the fixing mechanism 11 moves and drives the fixing end 41 to move. The driving mechanism 30 is connected with the sampling mechanism 12 and drives the sampling mechanism 12 to drive the sampling end 42 to rotate towards the excrement.
In yet another embodiment, the fixing mechanism 11 and the sampling mechanism 12 can drive the fixing end 41 and the sampling end 42 to move in combination respectively, so as to separate the fixing end 41 and the sampling end 42.
Example 2
Please refer to fig. 1-7.
In this embodiment, the sampling mechanism 12 is fixedly connected to the sampling end 42, and the fixing mechanism 11 drives the fixing end 41 to move along the axial direction of the sampler 40 so as to separate the fixing end 41 from the connection with the sampling end 42.
As described above, the sampling mechanism 12 of the present embodiment can pull out the external sampler 40, the positioning module 20 scans and positions the excrement in the toilet, and sends the scanned position information to the driving mechanism 30, and the driving mechanism 30 drives the sampling mechanism 12 and/or the connected sampler 40 to rotate toward the position of the excrement sample according to the position information, so that the sampling mechanism 12 completes the collection of the excrement sample.
As described above, the securing mechanism 11 may include a snap ring, a catch, or the like to secure the fixed end 41 of the sampler 40. The sampling mechanism 12 is fixedly connected with the sampling end 42 of the sampler 40, the fixing mechanism 11 drives the fixing end 41 to move, and the fixing end 41 is pulled out of the connection position of the sampling end 42.
For example, in the above process, the sampling mechanism 12 fixes the sampling end 42 of the sampler 40, and the fixing mechanism 11 moves and drives the fixing end 41 to move. The driving mechanism 30 is connected with the sampling mechanism 12, and drives the sampling mechanism 12 to drive the sampling end 42 to move towards the excrement.
In this embodiment, the stabilizing mechanism 11 includes a screw 113, a slider 112 mounted on the screw 113, a locking buckle 111 mounted on the slider 112 for fixedly mounting the fixed end 41, and a power feeding motor 114 for driving the slider 112 to move along the axial direction of the screw 113.
In this embodiment, the sampling mechanism 12 includes an outer sleeve 121 and a power mechanism 123 for driving the outer sleeve 121 to rotate;
the sampling end 42 is arranged in the inner cavity 1212 of the outer sleeve and fixedly clamped at the opening of the inner wall 1213 of the outer sleeve;
the power mechanism 123 drives the outer sleeve 121 to rotate, and the outer sleeve 121 drives the sampling end 42 to rotate relative to the fixed end 41 to unscrew the sampling end 42 from the fixed end 41.
In the embodiment, the sampling mechanism 12 includes an outer sleeve 121 and a power mechanism 123, and the sampling end 42 of the sampler 40 is clamped in the inner cavity 1212 of the outer sleeve and fixedly connected with the inner wall 1213 of the outer sleeve. The power mechanism 123 may drive the outer sleeve 121 to rotate, thereby driving the sampling end 42 to rotate.
The sampling end 42 and the fixed end 41 may be threaded. Therefore, when the sampling end 42 rotates, the fixed end 41 which is screwed together can move away from the sampling end 42 under the driving of the stabilizing mechanism 11. Thus, the sampling end 42 is pulled out.
Further, in this embodiment, the distal end of the outer sleeve 121 may be coupled to the drive mechanism 30 such that the drive mechanism 30 drives the sampling end 42 of the outer sleeve lumen 1212 in rotation.
In this embodiment, the outer surface of the outer sleeve 121 is provided with teeth 1211, and the power mechanism 123 is connected to the teeth 1211 to drive the outer sleeve 121 to rotate.
The power mechanism 123 may be coupled to the teeth 1211 of the outer sleeve 121 via gears, thereby driving the outer sleeve 121 to rotate.
In this embodiment, the sampling mechanism 12 further includes an inner sleeve 122 fixedly mounted to the outer sleeve lumen 1212, and the sampling end 42 is mounted to the inner sleeve lumen 1221;
the sampling end 42 comprises a needle tube 421 and a push rod 422, and the tail end 4212 of the needle tube is in threaded connection with the rod body of the push rod 422;
the front end 4211 of the needle tube is fixedly clamped with the opening of the inner sleeve wall 1213, and the push rod 422 is fixedly clamped with the inner sleeve wall 1222;
when the outer sleeve 121 drives the needle 421 to rotate, the push rod 422 moves axially along the inner sleeve wall 1222 to draw sample from the needle 421.
Where the sampling end 42 is tubular, the sampling mechanism 12 further includes an inner sleeve 122 fixedly mounted to the outer sleeve cavity 1212, it should be noted that the inner sleeve 122 is fixedly mounted to the outer sleeve cavity 1212, that means the inner sleeve 122 is fixed in the outer sleeve cavity 1212, the inner sleeve 122 does not rotate with rotation of the outer sleeve 121, and the outer sleeve 121 and the inner wall of the inner sleeve 122 may not be in direct contact.
Specifically, the needle 421-shaped sampling end 42 includes a needle 421 and a push rod 422, where the push rod 422 is in the inner cavity 1221 of the inner sleeve and is fixedly connected to the inner wall 1222 of the inner sleeve, and the fixed connection may be by a buckle connection with a concave-convex slot. The end 4212 of the needle cannula is threaded with the push rod 422, the needle cannula 421 may not directly contact the inner wall 1222 of the inner sleeve, and the front end 4211 of the needle cannula is fixedly connected with the inner wall 1213 of the outer sleeve in a manner of being clamped with each other through concave-convex grooves.
Thus, when the outer sleeve 121 is driven to rotate by the power mechanism 123, the outer sleeve 122 simultaneously drives the needle cannula 421 to rotate; also because the push rod 422 is fixedly connected to the inner sleeve 122, the inner sleeve 122 is stationary relative to the outer sleeve 121, so is the push rod 422. Because the connection between the push rod 422 and the needle tube 421 is a threaded connection, the push rod 422 will move backward due to the action of the threaded rotation, and the orifice of the needle tube 421 will form a negative pressure cavity to adsorb the sample due to the back-pulling of the push rod 422.
In this embodiment, the sampling device 100 further comprises a locking mechanism 50 for fixedly mounting the inner sleeve 122 to the inner cavity of the outer sleeve 121.
Based on the above structure, the sampling apparatus 100 further includes a locking mechanism 50 for securing the inner sleeve 122 within the inner cavity of the outer sleeve 121 without relative rotation of the inner sleeve 122.
In this embodiment, the locking mechanism 50 includes a locking button 51, an elastic member 52, and an inner sleeve connecting rod 53, one end of the inner sleeve connecting rod 53 is fixedly connected with the locking button 51 through the elastic member 52, and pressing of the locking button 51 drives the other end of the inner sleeve connecting rod 53 to abut against the top end of the inner sleeve 122.
The specific locking mechanism 50 includes an inner sleeve connecting rod 53 that fixes the inner sleeve 122, an elastic member 52 having one end connected to the inner sleeve connecting rod 53 and the other end connected to the locking button 51. When the locking button 51 is depressed, the inner sleeve connecting rod 53 abuts the top end of the inner sleeve 122 to lock the inner sleeve 122 stationary. When the locking button 51 is removed, the force exerted by the spring on the inner sleeve connecting rod 53 is removed and thus the inner sleeve connecting rod 53 does not lock the inner sleeve 122.
In this embodiment, the driving mechanism 30 drives the sampling mechanism 12 to perform spherical motion to reach the position of the sample according to the position information.
The above-mentioned means that the driving mechanism 30 drives the sampling mechanism 12 to make a spherical motion, specifically means that the driving mechanism 30 is connected to the end of the sampling mechanism 12, for example, the driving mechanism 30 is connected to the end of the outer sleeve 121 of the sampling mechanism 12, the connecting point is taken as a sphere center, the length of the outer sleeve 121 is taken as a radius, and the front end of the outer sleeve 121 is driven to make a spherical motion, so that the driving mechanism 30 can indirectly drive the sampling end 42 installed in the inner cavity 1212 of the outer sleeve to make a spherical motion, so that the sampling end 42 can reach the sample position more accurately to complete the sampling.
The driving mechanism 30 and the power mechanism 123 may be motors.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
