Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 to 6 schematically show a liquid-sealed insect-proof and odor-proof washbasin drainer according to an embodiment of the invention. As shown in the figure, the device comprises a front cover 1 and a body 2 which penetrates through a water drainage hole of the hand washing basin and is in threaded connection with the front cover 1.
Wherein, a valve core 3 is also arranged in the body 2.
The valve core 3 is cylindrical and provided with a through hole at the bottom, and the valve core 3 is directly inserted into the inlet side of the body 2 from the inside of the front cover 1.
The body 2 is internally provided with a liquid seal device. The liquid seal device realizes the one-way conduction of the water flow in the body 2 from top to bottom by storing water with a certain height in the liquid seal device.
The liquid seal device is composed of a liquid seal pipe 21 arranged in the body 2 and an outer sleeve 31 arranged outside the bottom of the valve core 3.
The liquid seal pipe 21 is inserted into the lower portion of the outer sleeve 31.
The upper part of the outer sleeve 31 is provided with a plurality of through holes 32, water flows out of the through holes 32, and the lower part of the outer sleeve 31 forms a blind end through a closed clapboard.
The distance between the liquid seal pipe 21 and the inner side wall of the body 2 is greater than the thickness of the corresponding position of the outer sleeve 31, the upper end of the liquid seal pipe 21 is inserted into the blind end of the outer sleeve 31, and the outer side wall of the lower end is connected with the inner side wall of the body 2 in a sealing manner.
The water flow flows out from the through hole 32 from the upper part, then enters the liquid seal pipe 21 from the upper part along the gap between the liquid seal pipe 21 and the outer sleeve 31, and finally flows out from the outlet side of the body 2 through the liquid seal pipe.
As shown in fig. 4, the height of the liquid seal pipe 21 is H, and the accumulated water with the height H is normally stored at the position of the liquid seal pipe 2.
The distance that the upper end of the liquid seal pipe 21 is inserted into the blind end of the outer sleeve 31 is h, and h is the liquid seal height of the liquid seal device.
Gas or liquid below the liquid seal pipe 21 generally needs to overcome the pressure corresponding to the water pressure h to enter the valve core from the liquid seal pipe.
Furthermore, a friction pad 6 and a sealing pad 5 are arranged between the front cover 1 and the body 2, and the friction pad 6 and the sealing pad 5 are respectively positioned at the inner side and the outer side of the lower water hole of the hand basin.
Further, an on-off valve 4 for controlling water flow is provided inside the valve core 3. The water storage and the water drainage of the hand basin can be realized through the switch valve 4.
Preferably, the on-off valve 4 is a push-on valve.
Specifically, the switch valve 4 mainly comprises a button 41 and a mandrel 45 connected with the button 41 through a hook 42, the mandrel 45 penetrates through a mandrel sleeve 46 and can slide up and down along the mandrel sleeve 46, the button 41 is connected with the mandrel sleeve 46 through a spring 43, two ends of the spring 43 are respectively connected with the button 41 and the mandrel sleeve 46, the outer diameter of the button 41 is matched with the inner diameter of the front cover 1, and the lower end of the mandrel sleeve 46 is connected with the bottom of the valve core 3.
The mandrel sleeve 46 may act as a lock for the mandrel 45.
When the button 41 is pressed to the bottom, the core shaft 45 is locked, the button 41 and the front cover 1 form a seal, and water can be stored in the hand basin;
when the button 41 is pressed again, the spindle 45 is unlocked, the button 41 pops up under the action of the spring 43, and the water stored in the hand basin is drained.
Specifically, the lower end of the spool sleeve 46 is connected with the bottom of the spool 3 through threads. Thereby pressing the on-off valve more conveniently for assembly and maintenance.
Further, the button 41 is connected to a screen 44, and the mandrel sleeve 46 passes through the bottom of the screen 44. When the switch valve 4 is opened, the button 41 pops out, water in the hand basin flows into the valve core 3 through the filter screen 44 through a gap between the button 41 and the front cover 1, and then flows out from the water outlet side of the body 2 through the duckbill valve 7 through the through hole at the bottom of the valve core 3. The filter screen 44 can filter out larger impurities in the water to prevent the larger impurities from blocking the sewer.
The liquid seal type insect-proof and odor-proof hand washing basin drainer adopting the technical scheme adopts the liquid seal device as a one-way opening valve device, can ensure that water flow falls and is discharged smoothly, and can also seal a water outlet hole when no water flow or the water flow is reversed, so that odor or cockroaches in a sewer can not go upwards reversely through the liquid seal device. Therefore, the functions of blocking the upward return of sewer odor and preventing insects can be realized. Compared with the existing similar products, the device has the advantages of simple structure, low price and small volume, and can save the installation space and further maximally utilize the space of the basin bottom of the hand basin.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
