Embodiment 2
On the basis of the embodiment 1, as shown in fig. 1-2 and fig. 5-7, a sponge block II 2010 is further included; four sponge blocks II 2010 are fixedly connected to the sponge block I209, and greasy dirt clamped in the groove I91 is erased through the sponge block II 2010, so that residues are avoided.
The device also comprises a supporting component; the first sponge block 209 is connected with a supporting component; the support assembly comprises a first 2011 and a second 2012; a first supporting block 2011 is fixedly connected inside each second sponge block 2010, the first supporting block 2011 is fixedly connected with the first sponge block 209, and the first supporting block 2011 is used for supporting the second sponge block 2010 to avoid the concave deformation of the second sponge block 2010; every two adjacent support blocks one 2011 are welded with a support block two 2012, and the support block two 2012 is fixedly connected with the sponge block one 209.
A scraper 2013 is also included; two ends of each second sponge block 2010 are fixedly connected with a scraping block 2013, and the scraping block 2013 is fixedly connected with a corresponding first supporting block 2011.
Also included is a round bar 2014; at least five round bars 2014 are welded on the inner side of each scraping block 2013, and an even number of grooves two 92 are formed in each round bar 2014.
In order to install the sealing ring conveniently, the sealing ring is arranged at the edge of the clamping groove of the valve 8 corresponding to the sealing ring, so that after the sealing ring is installed, a first groove 91 is formed on the upper side and the lower side of the sealing ring, and the first sponge block 209 is difficult to clean oil stains remained in the first groove 91, therefore, in the process of attaching the first sponge block 209 to the valve 8, the first sponge block 209 drives the second sponge block 2010 to move into the first groove 91 through the second sponge block 2010, and then when the electric turntable 205 drives the valve 8 to rotate, the oil stains remained in the first groove 91 are cleaned through the second sponge block 2010, so that the oil stains are prevented from being remained to influence the detection operation.
Because the sponge block two 2010 is relatively soft, the sponge block one 209 drives the sponge block two 2010 to move into the groove one 91, the sponge block two 2010 can rub with the surface of the sealing ring of the valve 8, so that the sponge block two 2010 is sunken to one side far away from the valve 8, and further the sponge block two 2010 cannot be completely inserted into the groove one 91, and the cleaning effect is low.
Because recess one 91 is easy to block and is hidden the greasy dirt of caking, and sponge piece one 209 can't erase the greasy dirt of caking, therefore, when electric turntable 205 drove valve 8 and rotated, strike off the greasy dirt of caking of blocking in recess one 91 through scraping the piece 2013, the greasy dirt of striking off is piled up and is adhered in scraping the piece 2013 inboard, during the use, will block the greasy dirt of caking of blocking in recess one 91 through scraping the piece 2013 and clear away, further improves greasy dirt cleaning efficiency.

Embodiment 3
On the basis of the embodiment 2, as shown in fig. 1-2 and fig. 8-9, an auxiliary component is also included; the connection block 208 is connected with an auxiliary component; the auxiliary component comprises an air pump II 2015, a pipeline IV 2016, a housing 2017, an elastic telescopic rod 2018, a sealing ring 2019 and a shifting block 2020; the connecting block 208 is provided with an air pump II 2015; the output end of the air pump II 2015 is communicated with two pipelines IV 2016; each of the four pipes 2016 is communicated with a housing 2017, wherein the housing 2017 can be square, and the housing 2017 can be round; four elastic telescopic rods 2018 are fixedly connected to the connecting blocks 208, and telescopic ends of the elastic telescopic rods 2018 are fixedly connected with corresponding housings 2017; each housing 2017 is fixedly connected with a sealing ring 2019, and the sealing rings 2019 are contacted with the connecting blocks 208; two shifting blocks 2020 are welded on each housing 2017, and each shifting block 2020 is made of alloy materials; a plurality of through holes 93 are formed among the connecting block 208, the first sponge block 209 and the second support block 2012.
Also included is a ring 2021; a plurality of circular rings 2021 are fixedly connected to the first sponge block 209, and the circular rings 2021 are positioned at the inner end parts of the corresponding through holes 93.
After the sponge block one 209 is used for a period of time, the greasy dirt on the sponge block one 209 needs to be cleaned, after cleaning, water absorbed in the sponge block one 209 needs to be extruded to enable the sponge block one 209 to be dried quickly, and the supporting block one 2011 and the supporting block two 2012 can interfere extrusion operation, so that the water at the position of the sponge block one 209 corresponding to the supporting block two 2012 cannot be extruded completely, and the drying effect is affected, therefore, the air pump two 2015 is started, the air pump two 2015 conveys air to the housing 2017 through the pipeline four 2016, and the air flows out of the through hole 93, so that the position of the sponge block one 209 corresponding to the supporting block two 2012 is air-dried through the air, and the drying effect of the sponge block one 209 is guaranteed.
The elastic telescopic rod 2018 is always in a stretching state, during the process of extruding the sponge block one 209, part of clear water flows into the housing 2017 from the through hole 93, so that the pulling block 2020 is manually pulled to move, the pulling block 2020 drives the housing 2017 to move, the elastic telescopic rod 2018 is further stretched, the housing 2017 drives the sealing ring 2019 to be far away from the connecting block 208, so that clear water in the housing 2017 is discharged, the pulling block 2020 is manually stopped, and the elastic telescopic rod 2018 rebounds to drive the housing 2017 and the sealing ring 2019 to move back to the original position.
Because the sealing washer on the valve 8 is made by the mould injection molding, consequently can form the burr on the sealing washer, remove the back with the burr still can remain a small amount of mild arch on the sealing washer, when sponge piece one 209 slides on the sealing washer, protruding motion to the through-hole 93 middle part stir its marginal motion, and then tear sponge piece one 209, consequently, through setting up ring 2021 at the inboard edge of through-hole 93, avoid protruding stirring sponge piece one 209 motion, and then protect sponge piece one 209, avoid appearing damaging the phenomenon.
It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the invention in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the invention.
