Side, the valve seat 1 further include a threaded connector 11, and the threaded connector 11 and the tubular structure of valve seat 1 are connected through a screw thread,
And threaded connector 11 is pressed on the other side of through-hole, to which valve seat 1 to be fixed on the bowl side of closestool.
Spool 2 therein is for acquiring urine or blocking urine, which is located in the hollow cavity of valve seat 1, and and valve
Seat 1 is slidably connected, and in specific setting, which is the structure of one end open, and open end is located at outside toilet basin, spool 2
End sealing, and collection port 13 is provided on the side wall of spool 2；In 2 upward sliding of spool, the collection port 13 of spool 2
It is exposed at outside valve seat 1, at this point it is possible to urine is collected by collection port 13, and the urine collected is connected from the open end of spool 2
Pipeline flow to urine detection mechanism and be detected.In 2 slide downward of spool, spool 2 is retracted in valve seat 1, collection port 13
It is blocked by valve seat 1, to avoid the urine that need not be acquired from flowing into spool 2.
When 2 opposite valve seat 1 of spool slides, slided by driving device 3 to provide power drive spool 2, the drive
Dynamic device 3 specifically includes：Driving motor 36, worm and gear component and auger device, wherein the output of driving motor 36
Axis makes the output shaft connecting worm 35 of worm screw 35 or driving motor 36, worm gear 31 be sleeved on the lateral wall of valve seat 1 and with
Valve seat 1 is rotatablely connected, and in specific setting, can be connected by bearing between worm gear 31 and valve seat 1, be existed between the two with reducing
Frictional force when rotation.The auger device includes two parts, and a part is the drive ring 34 coaxial with worm gear 31, the driving
It is fixedly connected, or in specific setting worm gear 31 is arranged with drive ring 34 into a single integrated structure between ring 34 and worm gear 31.Its
In, spiral chute 33 is provided on the drive ring 34, as shown in Figure 1, spiral chute 33 is arranged around the axis of drive ring 34.It is another
Part is sliding block 32, which is slidedly assemblied in the spiral chute 33, and is fixedly connected between the sliding block 32 and spool 2.
When driving motor 36 works, spiral chute 33 is driven to rotate, is located at the sliding block 32 in spiral chute 33 with movable valve plug 2 in valve seat
Sliding in 1, and when spool 2 rises to setting position, collection port 13 is exposed at outside valve seat 1.It is rotated backward in driving motor 36
When, the decline of spool 2 is contracted in valve seat 1.
In order to facilitate the connection understood between above-mentioned spool 2, valve seat 1 and driving device 3, below camera illustrate several portions
Structure between part in specific connection.
Firstly for for being slidably connected of valve seat 1 and spool 2, spool 2 and valve seat 1 are opposite slide when, pass through setting
Slide construction realize being slidably connected between the two, which includes protrusion and groove can adopt in specific setting
With different modes, as hollow cavity side wall on be provided with sliding slot, be provided on spool 2 be slidedly assemblied in it is convex in sliding slot
It rises；Or sliding slot is provided on spool 2, the protrusion being slidedly assemblied in sliding slot is provided on the side wall of hollow cavity.Pass through sliding slot
Cooperation with protrusion realizes being slidably connected between spool 2 and valve seat 1.Sliding slot to be arranged on valve seat 1, it is arranged on spool 2 convex
For rising, which can directly be process on the side wall of the hollow cavity of valve seat 1, such as direct by lathe or milling machine
It is processed, can also be cast directly on valve seat 1 when valve seat 1 is cast and form the sliding slot.Similarly, the protrusion on spool 2
It the equipment to form groove may be used is processed and form or be directly integrally cast with spool 2.In specific prepare, it is
Improve the stability when sliding of spool 2 opposite valve seat 1.Preferably, the number of the sliding slot is two, and of corresponding protrusion
Number is also two, and on the side wall of two sliding slots hollow cavity for being symmetricly set on valve seat 1.
In addition, for driving device 3, is realized by the cooperation of spiral chute 33 and sliding block 32 and spool 2 is pushed to slide
Effect, stability when in order to ensure that spool 2 lifts, in specific setting, the spiral angle of the spiral chute 33 is between 30
~45 ° such as 30 °, 35 °, 40 °, 45 ° of different angles.To avoid the spiral angle of spiral chute 33 is excessive from causing sliding block 32
The resistance being subject in sliding improves stability of the spool 2 in sliding.Rising to further improve spool 2
Or stability when declining, in specifically setting spiral chute 33, the number of spiral chute 33 is two, and two spiral chutes
The axisymmetrical of 33 opposite hollow cavitys is arranged；The number of sliding block 32 is two, and two sliding blocks 32 are symmetricly set on spool 2
On side wall.Improve the stability that driving device 3 drives spool 2 to slide.
In the present embodiment, in order to improve the sealing effect of spool 2 when not in use, the top of the spool 2 be provided with
The gasket that valve seat 1 coordinates.So that spool 2 when not in use, urine may not flow into spool 2, improves spool 2 and exists
Leakproofness when not in use, and then improve the accuracy of acquisition urine.
When the pipeline that the urine of collection is connected from the open end of spool 2 flows to urine detection mechanism and is detected, pass through
Channel in spool 2, and at least one channel being connected to collection port 13 is provided in spool 2.When for a channel, this is logical
Road is to collect the channel of urine, while the also urethra as backwash, and when needing to backwash, cleaning device is by pipeline by water
It is filled into the channel and is rinsed.In another specific embodiment, the number in channel is two, and one of those
Channel is to collect urine passageway 14, another channel is backwash channel 15.When in use, it will be rinsed by backwashing channel 15
The water that device provides is punched into spool 2, and two channel connections, and water, which is flowed into, to be collected in urine passageway 14 and along urine
Pipeline is gradually cleaned in the channel of collection, further improves accuracy of the spool 2 when collecting urine.
It can be seen from the above description that driving the sliding in valve seat 1 of spool 2 by driving device 3, and specifically make
Used time, when needing to collect urine, spool 2 is stretched out out of valve seat 1, is collected urine.When urine need not be collected, spool
2 are contracted in valve seat 1, and the collection port 13 on spool 2 is blocked by valve seat 1, to avoid collection port 13 contaminated, improve
Collect accuracy when urine.
The utility model embodiment additionally provides a kind of closestool, which includes closestool body, and is arranged in closestool sheet
The scheme in above-mentioned each embodiment may be used in internal urine sampling valve, sampling valve.The urine sampling valve is filled by driving
The sliding in valve seat 1 of 3 driving spools 2 is set, and when specifically used, when needing to collect urine, spool 2 is stretched out of valve seat 1
Go out, is collected urine.When that need not collect urine, spool 2 is contracted in valve seat 1, and 13 quilt of collection port on spool 2
Valve seat 1 blocks, and to avoid collection port 13 contaminated, improves accuracy when collecting urine.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
