Description

Technical Field

[0002] Washbasins are generally placed at home or in public places for washing. Washbasins are equipped with hot and cold water switches for adjusting the water temperature. The hot and cold water switches are connected to a hot water source and a cold water source respectively through two water pipes. However, when the hot and cold water switches are turned on to release hot water, the water in the water pipe connecting the hot and cold water switches and the hot water source stops flowing in the water pipe for a long time, causing the hot water in the water pipe to dissipate heat and become cold. When releasing hot water, the cold water in the water pipe will flow out first. Sometimes, people will release the water in the water pipe for convenience, resulting in a waste of water.

[0003] The mop pool is a device used to clean the mop. When using it, water needs to be placed in the mop pool in advance. After use, it is necessary to bend down and manually pull out the plunger on the bottom side of the mop pool to drain the dirty water, which is inconvenient to use.

[0004] On the other hand, the plunger switch at the drain outlet of the mop pool is very likely to shorten the life of its sealing rubber ring due to long-term contact with sewage.

[0005] The present invention designs a device which stores cooled water in a water pipe connected between a hot and cold water switch and a hot water source in a mop pool when a wash basin is used. When the mop needs to be washed, the stored water is used for washing. After washing, a drain outlet at the bottom of the mop pool is directly opened through the lower end of the mop, and sewage is automatically discharged without manual bending over for operation. After the sewage is discharged, the drain outlet at the lower end of the mop pool is automatically closed, which is convenient for the next water storage. At the same time, the plunger switch is improved to extend the life of the sealing rubber ring. Summary of the invention

[0027] Compared with traditional water-saving technology, the beneficial effects of the design of the present invention are as follows:

[0028] 1. The water-saving device designed in the present invention is that when the hot and cold water switches on the wash basin are turned on to release hot water, the water in the hot water pipe connected between the hot water inlet of the hot and cold water switch and the hot water source stops flowing in the water pipe for a long time, causing the hot water in the water pipe to dissipate heat and become cold. When releasing hot water, the cold water in the water pipe will flow out first. Sometimes people will release the water in the water pipe for convenience, resulting in a waste of water. Therefore, before turning on the hot and cold water switches to release hot water, first turn on the control switch to allow the water in the hot water pipe connected between the hot water inlet of the hot and cold water switch and the hot water source to flow out, pass through the control switch and the mop pool outlet pipe, and flow into the mop pool for storage for washing the mop.

[0029] 2. The water-saving device designed in the present invention can directly open the drain outlet at the bottom of the mop pool through the lower end of the mop after cleaning the mop, and the sewage is automatically discharged without the need for manual bending over to operate. After the sewage is discharged, the drain outlet at the bottom of the mop pool will automatically close, which is convenient for the next water storage.

[0030] 3. The present invention designs a first arc-shaped cone surface at the lower end of the mop pool drain outlet, and designs a second arc-shaped cone surface at the upper end of the water-saving valve plunger. Through the cooperation of the first arc-shaped cone surface and the second arc-shaped cone surface, the sealing performance of the mop pool drain outlet in the closed state is improved.

[0031] 4. The mop pool designed in the present invention has a water storage chamber at the lower end, in which a portion of water is filtered and stored in advance. When the water-saving valve plunger moves up and resets, the water in the water storage chamber flows out to clean the impurities stuck on the water-saving valve plunger. In addition, during the cleaning process, the water-saving valve plunger rotates and moves up with the cooperation of the threaded groove on the threaded rod and the spiral slider on the trigger sleeve, thereby improving the cleaning effect and extending the service life of the sealing ring.

[0032] 5. The reason why the drainage direction of the drainage hole of the present invention is designed to be along the tangent direction of the inner circular surface of the mop pool drainage pipe is that the water flowing out through the drainage hole has the effect of spraying around the outer circular surface of the water-saving valve plunger, thereby improving the cleaning effect of the water-saving valve plunger.

[0033] 6. The present invention is designed with a support bar to ensure that when the lower end of the mop is squeezed to trigger the protrusion, a certain gap can be left between the mop and the drain outlet at the lower end of the mop pool for sewage to be discharged. The function of the filter is to filter the sewage flowing into the water outlet cavity. The function of the nested groove is to prevent the mop from lifting the filter together with the filter during the cleaning process, thereby affecting the filtering effect of the water flowing into the water storage cavity.

[0055] When the wash basin 2 is in use, the control switch 6 is first turned on to stop the cooling water in the hot water pipe connected between the hot water inlet of the hot and cold water switch 4 and the hot water source from flowing out, and flows into the mop pool 3 through the control switch 6 and the mop pool outlet pipe 9 for storage for future use; when the cooling water in the hot water pipe has completely flowed out and the hot water in the hot water source has flowed into the hot water pipe, the control switch 6 is turned off and the hot and cold water switch 4 is turned on.

[0056] After the mop pool 3 is used, the water-saving valve 11 is opened directly by squeezing and triggering, so that the sewage in the mop pool 3 is discharged; after the sewage is discharged, the water-saving valve 11 is automatically reset to close the drain outlet.

[0057] like Figure 2 As shown, the wash basin 2 is also equipped with a temperature measuring piece for measuring the temperature of water flowing from the three-way valve into the mop pool outlet pipe 9. The temperature of the water in the water pipe section can be directly observed through the temperature measuring piece, and the control switch 6 can be controlled at any time according to actual needs.

[0058] like Figure 2 As shown, the water pipe connected between the three-way valve and the mop pool water outlet pipe 9 is connected to the mop pool water outlet pipe 9 through a one-way valve 8; the reason for designing the one-way valve 8 is to prevent the water flowing into the water outlet switch 10 from flowing back through the water outlet switch 10 into the water pipe connected between the three-way valve and the mop pool water outlet pipe 9 when the water outlet switch 10 on the upper side of the mop pool 3 is normally opened, causing inconvenience in use.

[0059] like Figure 5 As shown, the lower end of the drain outlet of the mop pool 3 has a first arcuate conical surface 41; because the two mutually matched arcuate conical surfaces have better sealing performance when matched with the straight surface or the inclined surface, the present invention designs the first arcuate conical surface 41 at the lower end of the drain outlet of the mop pool 3, as shown in FIG. Fig.15 As shown, a second arcuate cone surface 42 is designed at the upper end of the water-saving valve plunger 32, and the first arcuate cone surface 41 and the second arcuate cone surface 42 cooperate with each other to improve the sealing performance of the drain outlet of the mop pool 3 in the closed state.

[0060] like Fig.14 As shown, the water-saving valve 11 includes a water-saving valve plunger 32, a water-saving valve housing 33, a support plate 34, a trigger sleeve 35, a mounting housing 37, a drain pipe 38, a trigger protrusion 39, a connecting column 40, a threaded rod 43, a threaded groove 44, a spiral slider 45, a telescopic rod 16, a limit mechanism 17, and a damper 18, wherein as Fig.13 As shown, the lower end of the water-saving valve housing 33 has a drain pipe 38, as shown in FIG. Figure 5As shown, a mounting shell 37 is fixedly mounted on the outer circumferential surface of the water-saving valve housing 33, and the upper end of the water-saving valve housing 33 is detachably mounted on the lower side of the drain outlet of the mop pool 3, and the drain pipe 38 is connected to the sewer pipe; Fig.15 As shown, the upper end of the water-saving valve plunger 32 has a second arc-shaped cone surface 42, and the lower end of the water-saving valve plunger 32 is installed with a threaded rod 43, and the threaded rod 43 is provided with a threaded groove 44, as shown in FIG.

Fig.11 , 12 As shown in FIG. 14 , a plurality of trigger sleeves 35 are respectively installed on the inner side of the water-saving valve housing 33 through three circumferentially evenly distributed support plates 34, and the spiral slider 45 on each trigger sleeve 35 corresponds to the thread groove 44 on the threaded rod 43 in a one-to-one spiral sliding fit; Fig.15 As shown, the upper end of the water-saving valve plunger 32 is installed with a trigger protrusion 39 through a connecting column 40; the trigger sleeve 35 is fixed in the water-saving valve housing 33 by a circumferentially distributed support plate 34, and is stationary relative to the water-saving valve housing 33; in the present invention, in order to realize that when the threaded rod 43 moves downward, the threaded rod 43 can move downward while rotating through the spiral cooperation of the threaded groove 44 opened thereon and the spiral slider 45 on the inner circular surface of the trigger sleeve 35; therefore, under the condition of ensuring that the trigger sleeve 35 is fixed, the spiral lead angle of the threaded groove 44 on the threaded rod 43 and the spiral lead angle of the spiral slider 45 on the trigger sleeve 35 must be guaranteed to be within a certain large range.

[0061] like Fig.16 As shown, the damper 18 includes a damping inner rod 46 and a damping shell 49. The lower end of the damping shell 49 is fixedly mounted on the bottom surface of the mounting shell 37. A second spring 48 is installed between the damping inner rod 46 and the damping shell 49.

[0064] like Figure 6 , 11 As shown in FIG. 12 , a limiting mechanism 17 is also installed on the inner wall surface of the mounting shell 37 to limit the downward movement of the telescopic sleeve 52.

[0065] like Fig.16 As shown, a mounting disc 47 is fixedly mounted on the upper end of the damping inner rod 46 , an upper end of a second spring 48 is fixedly mounted on the lower end of the mounting disc 47 , and a lower end of the second spring 48 is fixedly mounted on the upper end surface of the damping shell 49 .

[0066] like Fig.17 As shown, a clamping block 54 is fixedly mounted on the outer circumferential surface of the lower end of the telescopic sleeve 52 .

[0067] like Fig.18 As shown, the above-mentioned limiting mechanism 17 includes a limiting block 55, a limiting shell 56, a limiting spring 57, a first inclined surface 58, and a second inclined surface 59, wherein one end of the limiting shell 56 is fixedly mounted on the inner wall surface of the mounting shell 37, and the upper and lower sides of one end of the limiting block 55 are respectively provided with a first inclined surface 58 and a second inclined surface 59, and the angle between the first inclined surface 58 and the sliding plane of the limiting block 55 is smaller than the angle between the second inclined surface 59 and the sliding plane of the limiting block 55, and the other end of the limiting block 55 is slidably mounted in the limiting shell 56, and a limiting spring 57 is installed between one end of the limiting block 55 located in the limiting shell 56 and the inner end surface of the limiting shell 56. The purpose of designing the included angle between the first inclined surface 58 and the sliding plane of the limit block 55 to be smaller than the included angle between the second inclined surface 59 and the sliding plane of the limit block 55 is to ensure that the extrusion force on the upper side of the limit block 55 moving into the limit shell 56 is greater than the extrusion force on the lower side of the limit block 55 moving into the limit shell 56.

[0068] One end of the limit block 55 having a first inclined surface 58 and a second inclined surface 59 is matched with the clamping block 54 .

[0069] like Fig.13 As shown, a square slide groove 36 is provided between the mounting shell 37 and the water-saving valve housing 33.

[0071] In order to ensure that the third spring 53 has sufficient pressure to drive the damping inner rod 46 to move downward, the elastic coefficient of the third spring 53 designed in the present invention is greater than the elastic coefficient of the second spring 48.

[0072] In the present invention, in order to ensure that the second spring 48 has sufficient pressure to drive the clamping block 54 to squeeze the limiting block 55 to move inward, the inclination angle between the second inclined surface 59 and the sliding plane of the limiting block 55 is designed to be large enough.

[0073] The present invention uses the damper 18 to achieve the slow upward reset of the telescopic rod 16, that is, the slow upward movement of the water-saving valve plunger 32, in order to increase the time for the sewage to be discharged after the mop is lifted, thereby ensuring that the sewage can be completely discharged.

[0074] The extrusion force exerted by the upper side of the limit block 55 of the present invention toward the limit shell 56 is greater than the extrusion force exerted by the lower side of the limit block 55 toward the limit shell 56, ensuring that the third spring 53 can store sufficient compression force to push the damping inner rod 46 downward and compress the second spring 48.

[0075] like Figure 7 As shown, the lower end of the mop pool 3 has a water storage chamber 60, and the water storage chamber 60 and the bottom surface of the mop pool 3 are intermittently provided with evenly distributed water holes 19; Figure 4 , 8 As shown, a plurality of support bars 12 are evenly installed on the bottom surface of the mop pool 3, and the water holes 19 are located between adjacent support bars 12; nesting grooves 20 sunk into the lower side of the bottom surface of the mop pool 3 are opened between adjacent support bars 12, and a filter screen 13 for filtering impurities is nested and installed in each nesting groove 20.

[0076] The purpose of designing the support bar 12 is to ensure that when the lower end of the mop squeezes the triggering protrusion 39, there is a certain gap between the mop and the drain outlet at the lower end of the mop pool 3 for the sewage to be discharged. The function of the filter 13 is to filter the sewage flowing into the water outlet cavity. The function of designing the nesting groove 20 is to prevent the mop from lifting the filter 13 during the cleaning process, thereby affecting the filtering effect of the water flowing into the water storage cavity 60.

[0077] like Fig. 9 As shown, a plurality of mounting grooves 22 are uniformly opened on the inner circumferential surface of the lower end of the water storage chamber 60, one end of the mounting groove 22 is opened with a control valve slide groove 21, one end of the control valve slide groove 21 is opened with a drainage groove 24, one end of the drainage groove 24 is opened with an arc groove 25 and a drainage hole 2319 that penetrate the drainage pipe 38 of the mop pool 3, and the drainage direction of the drainage hole 2319 is along the tangent direction of the inner circumferential surface of the drainage pipe 38 of the mop pool 3; a switch control valve 14 is installed in each group of mounting grooves 22, control valve slide grooves 21, drainage grooves 24, and arc grooves 25.

[0078] like Fig.10 As shown, the switch control valve 14 includes an arc-shaped push rod 26, a control valve plunger 27, a first spring 28, a guide rod 29, a fixed disc 30, and a first cone 31, wherein the fixed disc 30 having a plurality of leaking holes is fixedly mounted on one end of the mounting groove 22 close to the water storage chamber 60, and two first cones 31 are symmetrically opened at both ends of the control valve plunger 27, and the control valve plunger 27 is slidably mounted in the control valve slide 21 opened at the lower end of the mop pool 3, and the two first cones 31 on the control valve plunger 27 are respectively connected to the corresponding control valve slide 21 The two ends of the control valve plunger 27 cooperate with each other, one end of the control valve plunger 27 is fixedly installed with three guide rods 29 evenly distributed in the circumference, the end of the guide rod 29 away from the control valve plunger 27 is slidably installed on the fixed disc 30, and a first spring 28 is installed between the end of the control valve plunger 27 with the guide rod 29 and the fixed disc 30; the other end of the control valve plunger 27 is fixedly installed with an arc-shaped push rod 26, and the end of the arc-shaped push rod 26 away from the control valve plunger 27 passes through the corresponding arc groove 25 and cooperates with the second arc conical surface 42 on the water-saving valve plunger 32.

[0079] In the initial state of the present invention, the control valve plunger 27 contacts and seals with one end of the control valve slide 21 near the water storage chamber 60 under the action of the water-saving valve plunger 32 on the arc-shaped push rod 26. The reason why the drainage direction of the drainage hole 2319 of the present invention is designed to be along the tangent direction of the inner circular surface of the drainage pipe 38 of the mop pool 3 is that the water flowing out through the drainage hole 2319 is along the tangent direction of the inner circular surface of the drainage pipe 38 of the mop pool 3, and has the effect of spraying around the outer circular surface of the water-saving valve plunger 32, thereby improving the cleaning effect of the water-saving valve plunger 32.

[0080] The trigger protrusion 39 designed in the present invention has its upper end higher than the support bar 12 when the water-saving valve 11 is closed. This design is used to ensure that the mop can smoothly trigger the plunger 32 of the water-saving valve.

[0081] Specific working process: when using the water-saving device designed in the present invention, before turning on the hot and cold water switches 4 to release hot water, first turn on the control switch 6, so that the water in the hot water pipe connected between the hot water inlet of the hot and cold water switches 4 and the hot water source flows out, passes through the control switch 6 and the mop pool outlet pipe 9, flows into the mop pool 3 and is stored for washing the mop.

[0082] When the mop is cleaned, the trigger protrusion 39 is squeezed downward by the lower end of the mop, and the trigger protrusion 39 drives the water-saving valve plunger 32 to move downward through the connecting column 40, so that the second arc-shaped cone surface 42 on the water-saving valve plunger 32 is separated from the first arc-shaped cone surface 41 on the drain outlet of the mop pool 3, and the sewage is discharged from the gap between the two arc-shaped cone surfaces.

[0083] When the water-saving valve plunger 32 moves downward, on the one hand, the water-saving valve plunger 32 will drive the connecting rod 50 to move downward, and the connecting rod 50 moves downward to drive the telescopic inner rod 51 to move downward. At this time, the block 54 installed at the lower end of the telescopic outer sleeve 52 contacts the first inclined surface 58 on the limit block 55, and the limit block 55 limits the telescopic outer sleeve 52; therefore, the downward movement of the telescopic inner rod 51 will squeeze the third spring 53, so that the first spring 28 is compressed, and the third spring 53 is compressed to transmit the downward force to the telescopic outer sleeve 52, and the telescopic outer sleeve 52 squeezes the limit block 55 through the block 54; when the third spring 53 is compressed to a certain extent, the limit block 55 gradually moves toward the limit shell 56 under the action of the first inclined surface 58. When the limit block 55 is completely disengaged from the clamping block 54, the limit block 55 loses the limit on the telescopic cover 52. At this time, the telescopic cover 52 will quickly press down the damping inner rod 46 under the action of the compressed third spring 53, so that the damping inner rod 46 moves downward relative to the damping shell 49. At the same time, the second spring 48 is compressed, and the previously compressed third spring 53 is released. During the release process, the user can judge the end of the squeezing process by the release of the force felt by the mop and the sound of the clamping block 54 breaking through the limit block 55, and lift the mop; when the limit block 55 is disengaged from the downwardly moving clamping block 54, the clamping block 54 moves downward, and the limit block 55 will extend again under the action of the limit spring 57. From the above analysis, it can be seen that the setting of the clamping block 54 and the limit block 55 can enable the user to know the degree of downward pressure to ensure the degree of compression of the damping rod, and then ensure that the recovery time of the damping rod is long enough to ensure that all sewage is discharged.

[0084] On the other hand, when the water-saving valve plunger 32 is pushed down, the control valve plunger 27 will move along the control valve slide groove 21 to the side of the drain hole 2319 under the restoring force of the first spring 28. During the movement, the control valve plunger 27 does not contact the two ends of the control valve slide groove 21, and the water in the water storage chamber 60 flows out through the control valve slide groove 21, the drain groove 24 and the drain hole 2319. When the water-saving valve plunger 32 continues to move downward, the control valve plunger 27 will move toward the drain hole 2319 under the restoring force of the first spring 28. The plug 27 will contact and seal with one end of the control valve slide 21 near the drain hole 2319, and the water in the water storage chamber 60 will no longer continue to flow out; because the control valve plunger 27 moves downward at a relatively fast speed, the amount of water flowing out of the water storage chamber 60 during the downward movement is very small and can be ignored; then the control valve plunger 27 continues to move downward to separate the arc-shaped push rod 26 from the second arc-shaped cone surface 42 of the control valve plunger 27, and the control valve plunger 27 is always in contact and seal with one end of the control valve slide 21 near the drain hole 2319. In the present invention, after the mop is lifted, due to the action of the damper 18, the telescopic rod 16 moves upward at a relatively low speed, that is, the telescopic rod 16 moves upward slowly; in the process of the telescopic rod 16 moving upward, when the block 54 on the telescopic sleeve 52 contacts the second inclined surface 59 on the limit block 55 that is extended again, under the action of the second spring 48, the limit block 55 moves inward again until the block 54 moves to the upper side of the limit block 55, and the limit block 55 extends again under the action of the limit spring 57; and the upward movement of the telescopic rod 16 will drive the water-saving valve plunger 32 to move upward through the connecting rod 50.

[0085] During the upward movement, on the one hand, the second arc-shaped conical surface 42 on the water-saving valve plunger 32 contacts the first arc-shaped conical surface 41 at the lower end of the drain outlet of the mop pool 3, closing the drain outlet of the mop pool 3. Therefore, in the present invention, when the water-saving valve 11 is in a closed state, the drain outlet of the mop pool 3 is in a closed state, and the water flowing into the mop pool 3 will be stored.

[0086] On the other hand, when the control valve plunger 27 moves upward, the upward movement speed is slow due to the action of the damper 18, and the time that the control valve plunger 27 stays in the middle of the control valve slide groove 21 becomes longer. In this way, the amount of water flowing out of the water storage chamber 60 is large enough to clean the impurities stuck on the water-saving valve plunger 32, and during the cleaning process, the water-saving valve plunger 32 rotates and moves upward with the cooperation of the threaded groove 44 on the threaded rod 43 and the spiral slider 45 on the trigger sleeve 35, thereby improving the cleaning effect.
