Description

Technical Field

[0001] The present invention relates to the field of bathroom faucets, and more particularly to a bathroom faucet. Background Art

[0002] As an indispensable component in bathroom decoration, bathroom faucets bear important responsibilities. They are usually composed of four parts: the water outlet, the control part, the fixed part and the water inlet. In the water outlet link, in order to meet different washing needs, current bathroom faucets are usually equipped with a bubble net at the water outlet to reduce the occurrence of splashing after water outlet. However, the water inlet of the bathroom faucet generally comes from the municipal water supply. The cations contained in tap water will harden the water quality and cause the bubble net to become blocked and lose its corresponding effect. Therefore, it is necessary to clean and dredge the surface scale of the bubble net in the water outlet of the bathroom faucet.

[0003] In the prior art, when cleaning and unblocking scale on the surface of the bubble net, the rotation of the beam is mostly used to drive the rotation of the internal impeller blade group, which then rubs against the surface of the bubble net to achieve a cleaning effect. However, the size of the scale after friction cleaning is still larger than the diameter of the bubble net. This makes it difficult to remove the scale that has been cleaned and peeled off from the bathroom faucet, and it still remains in the pipe, threatening the water flow inside the bathroom faucet and is not conducive to achieving effective and convenient bathroom faucet cleaning operations.

[0004] To this end, we have proposed a bathroom faucet. Based on friction cleaning, it drives the movement of the friction cleaning component to create a gap between the foaming net mounting part and the inner wall of the pipe, so that the scale that has been peeled off and cleaned can be transferred out of the pipe of the water outlet part of the bathroom faucet along the reserved gap under the influence of water flow, thereby achieving the purpose of effective and convenient foaming net cleaning and dredging. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a bathroom faucet, which can be cleaned and unblocked through the cleaning unit. When cleaning the No. 1 bubble net, the tail end water outlet is rotated to drive the transmission rod to rotate so that the upper No. 2 bubble net moves downward. At this time, the water outlet is in a closed state, and the movable slider is disengaged from the annular hoop under the driving action of the connecting rod, so that a gap is generated between the annular hoop and the inner wall of the water outlet, and the surface friction between the upper No. 2 bubble net and the No. 1 bubble net is used to clean the scale on the surface of the No. 1 bubble net. After that, water is supplied to the inside of the water outlet, and then the scale is caused to flow out through the gap with the help of the water flow and then flow out through the tail end water outlet, thereby realizing the discharge and cleaning of the scale and reducing the residue after scale cleaning. At the same time, with the help of the flocculation mixture flowing out from the liquid storage cavity, the suspended particles remaining in the water outlet are flocculated and discharged in a concentrated manner, thereby improving the quality of scale cleaning.

[0011] The tail end of the water outlet faucet is rotatably connected to a tail end water outlet component, and the net diameter of the tail end water outlet component is larger than the No. 2 bubble net.

[0012] Furthermore, the impeller blade group and the second foaming net are installed in two groups, and the impeller blade group is a twisted design.

[0013] Furthermore, a pressurized water outlet is provided inside the impeller blade group, and the cross-section of the pressurized water outlet is a trapezoidal structure that is wide at the top and narrow at the bottom.

[0014] Furthermore, the annular hoop is made of rubber material, the surface of the annular hoop is covered with a protective coating, a liquid storage cavity is provided inside the annular hoop, and flocculant is stored inside the liquid storage cavity, and a liquid outlet is provided on the surface of the liquid storage cavity that contacts the movable slider.

[0015] Furthermore, the diameter of the liquid outlet hole is 0.1-0.3 mm, and the flocculant is a mixed liquid of an inorganic high molecular polymer flocculant and a coagulant aid.

[0016] Furthermore, a transmission rod is installed at the center position of the tail end water outlet member, the outer surface of the transmission rod is sleeved with a transmission member, and the top end of the transmission member is fixedly connected to the tail end of the movable screw.

[0017] Furthermore, the end of the water faucet away from the tail water outlet is connected to a water supply metal hose, and the tail end surface of the water supply metal hose is sleeved with a telescopic movable rod, and the length of the telescopic movable rod is the same as the length of the water supply metal hose in the retracted state, and the tail end surface of the telescopic movable rod is connected to a piston ring, the outer side of the piston ring is sleeved with a fixed transmission rod, and the inner wall of the fixed transmission rod is slidably connected to the piston ring.

[0018] Furthermore, the surface of the fixed transmission rod is penetrated and connected with a symmetrically arranged cold water inlet and a hot water inlet, and the tail ends of the cold water inlet and the hot water inlet both extend into the interior of the water supply metal hose.

[0019] Furthermore, the arrangement area of ​​the threads on the surface of the movable screw is located in the middle of the two groups of No. 2 foaming nets.

[0020] Furthermore, a one-way plug is installed on the inner wall of the water outlet faucet, and the one-way plug is located above the cleaning and dredging unit.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) This solution is equipped with a cleaning and unblocking unit. When cleaning the No. 1 bubble net, the tail end water outlet is rotated to drive the transmission rod to rotate so that the upper No. 2 bubble net moves downward. At this time, the water faucet is in a closed state. The movable slider is driven by the connecting rod to separate from the annular hoop, so that a gap is formed between the annular hoop and the inner wall of the water faucet. After the upper No. 2 bubble net approaches the surface of the No. 1 bubble net, as the movable screw continues to move downward, the upper No. 2 bubble net still rotates with the movable screw but is intercepted by the No. 1 bubble net, and then rubs against the surface of the No. 1 bubble net, thereby cleaning the scale on the surface of the No. 1 bubble net. After that, water is supplied to the inside of the water faucet, and then the scale is discharged through the gap with the help of the water flow and then flows out through the tail end water outlet, thereby cleaning the scale and reducing the residue after cleaning.

[0024] (2) This solution is equipped with two sets of No. 2 bubble nets and two sets of impeller blades. When the tail end water outlet is rotated, the two sets of impeller blades rotate, and then rub the surface of the No. 2 bubble net in contact with them, thereby cleaning the scale on the surface of the No. 2 bubble net and dropping it through the mesh of the No. 2 bubble net to the surface of the No. 1 bubble net. It is then discharged in a concentrated manner through the gap exposed by the moving slider. In addition, the two sets of impeller blades can play a supplementary cleaning effect on the surface of the No. 2 bubble net when rotating. On the premise of ensuring that this bathroom faucet has multiple bubble effects, the comprehensiveness of the scale cleaning on the surface of the bubble net is guaranteed.

[0025] (3) This solution is equipped with a pressurized water inlet. When the water flows through the impeller blade group, it flushes the surface of the No. 2 bubble net through the inside of the pressurized water inlet, thereby allowing the scale remaining on the surface of the No. 2 bubble net after friction cleaning to be flushed away, thereby enhancing the scale cleaning ability. At the same time, the porous design is used to reduce the resistance of the impeller blade group to the water flow.

[0026] (4) This solution is equipped with a liquid outlet and a liquid storage chamber. After the slider moves away from the surface of the annular hoop, the liquid storage chamber is squeezed by the impact of the water flow, so that the mixed liquid inside the liquid storage chamber flows out with the water flow. By checking the scale particles suspended in the water flow and flocculating them into agglomerates, it can be judged whether the scale inside the faucet is completely cleaned. At the same time, the suspended particles remaining inside can be settled, making the scale inside the faucet cleaned more completely. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1:

[0043] See also Figures 1-8 A bathroom faucet includes a water outlet faucet 4 and a cleaning and unblocking unit 8. The cleaning and unblocking unit 8 is installed inside the water outlet faucet 4. The cleaning and unblocking unit 8 includes a movable screw 801, an impeller blade group 802, an annular hoop 803, a connecting rod 804, a movable slider 805, a No. 1 bubble net 806 and a No. 2 bubble net 807;

[0044] The faucet 4 is provided with a hollow annular hoop 803 on the inner wall near the tail end, and a No. 1 bubbling net 806 is installed on the inner side of the annular hoop 803, and an arc-shaped movable slider 805 is slidably installed on the outer side of the annular hoop 803, and the movable slider 805 and the annular hoop 803 form a complete circle, and an L-shaped connecting rod 804 is installed on the top of the movable slider 805 through a rotating joint, and the tail end of the connecting rod 804 is connected to the No. 2 bubbling net 807, and the net diameter of the No. 2 bubbling net 807 is larger than that of the No. 1 bubbling net 806, and a movable screw 801 is threadedly connected through the center position of the No. 1 bubbling net 806, and the surface of the movable screw 801 is sleeved with an impeller blade group 802, and the impeller blade group 802 is located on the side of the No. 2 bubbling net 807 away from the No. 1 bubbling net 806, and the threaded area on the surface of the movable screw 801 is located in the middle of the two groups of No. 2 bubbling nets 807;

[0045] The tail end of the water outlet faucet 4 is rotatably connected to the tail end water outlet part 9. The net diameter of the tail end water outlet part 9 is larger than the No. 2 bubble net 807. A transmission rod 901 is installed at the center position of the tail end water outlet part 9. The outer surface of the transmission rod 901 is sleeved with a transmission part 902, and the top end of the transmission part 902 is fixedly connected to the tail end of the movable screw 801.

[0046] Specifically, the two groups of No. 1 bubbling nets 806 and the impeller blade group 802 are not symmetrically arranged about the No. 1 bubbling net 806, but the diameters of the No. 1 bubbling net 806 and the No. 2 bubbling net 807 are the same, and the bottom end of the surface of the impeller blade group 802 is in contact with the surface of the No. 1 bubbling net 806. The No. 1 bubbling net 806 is slidably connected to the surface of the movable screw 801, and the surface of the movable screw 801 is provided with a limiter, which is located on both sides of the impeller blade group 802.

[0047] When cleaning the No. 1 foaming net 806, the tail end water outlet part 9 is rotated to drive the transmission rod 901 to rotate. The transmission rod 901 rotates and drives the surface transmission part 902 to rotate and move downward. At this time, the water tap 4 is in a closed state. The movable slider 805 is driven by the connecting rod 804 to break away from the annular hoop 803, so that the structure of the original whole circular block and the inner wall of the water tap 4 have a gap. After that, after the No. 2 foaming net 807 above is close to the surface of the No. 1 foaming net 806, as the movable screw 801 continues to move downward, the water tap 4 is in a closed state. The movable screw 801 moves, and the upper No. 2 bubbling net 807 still rotates with the movable screw 801 but is intercepted by the No. 1 bubbling net 806, and then rubs against the surface of the No. 1 bubbling net 806, so as to clean the scale on the surface of the No. 1 bubbling net 806, and then the water outlet 4 is opened to supply water inside the water outlet 4, and then with the help of the water flow, the cleaned scale is carried away through the gap left by the movement of the movable slider 805 and the inner wall of the water outlet 4, and then flows out through the tail end water outlet part 9, so as to realize the discharge and cleaning of the scale and reduce the residue after the scale cleaning.

[0048] At the same time, when the tail end water outlet part 9 is rotated in the opposite direction, the downward moving slider 805 can be moved upward until the moving slider 805 is completely fitted with the surface of the annular hoop 803 and the thread movement distance of the movable screw 801 reaches the limit, and no longer drives the upper No. 2 foaming net 807 to move upward. At this time, the surface of the lower No. 2 foaming net 807 is fitted with the surface of the No. 1 foaming net 806, and the complete splicing operation of the annular hoop 803 is achieved;

[0049] When the tail end water outlet member 9 is rotated, both impeller blade groups 802 rotate, thereby rubbing the surface of the second bubbling net 807 in contact therewith, thereby cleaning the scale on the surface of the second bubbling net 807 and dropping it through the mesh of the second bubbling net 807 to the surface of the first bubbling net 806, and then being discharged in a centralized manner through the gap exposed by the moving slider 805;

[0050] By setting two sets of No. 2 bubble nets 807 and one set of No. 1 bubble net 806, a triple bubble design is set to enhance the bubble effect of the bathroom faucet;

[0051] During the upward movement of the slider 805, the second bubbling net 807 below rubs and cleans the bottom surface of the first bubbling net 806 under the action of rotation, thereby achieving double-sided cleaning of the first bubbling net 806 and improving the scale cleaning quality of the first bubbling net 806;

[0052] Since the flushing direction of the water flow is in the same axial direction as the installation direction of the impeller blade group 802, the rotational pushing effect on the impeller blade group 802 when the water flows through is not obvious, which can reduce the scale cleaning caused by the rotation cleaning of the impeller blade group 802 when the water flows through, and avoid the presence of scale impurities in the water, which affects the water quality.

[0053] See also Figure 9 The impeller blade group 802 and the second bubble net 807 are installed in two groups, among which the impeller blade group 802 is a twisted design, and a pressurized water outlet 8021 is provided inside the impeller blade group 802, and the cross-section of the pressurized water outlet 8021 is a trapezoidal structure that is wide at the top and narrow at the bottom.

[0054] Specifically, when the water flows through the impeller blade group 802, it flushes the surface of the No. 2 bubble net 807 through the inside of the pressurized water outlet 8021, so that the scale remaining on the surface of the No. 2 bubble net 807 after friction cleaning can be flushed away, thereby enhancing the scale cleaning ability. At the same time, the porous design is used to reduce the resistance of the impeller blade group 802 to the water flow.

[0055] See also Figure 10The annular hoop 803 is made of rubber material, and the surface of the annular hoop 803 is covered with a protective coating. A liquid storage chamber 8032 is provided inside the annular hoop 803, and flocculant is stored inside the liquid storage chamber 8032. A liquid outlet hole 8031 ​​is provided on the surface of the liquid storage chamber 8032 in contact with the movable slider 805. The diameter of the liquid outlet hole 8031 ​​is 0.1-0.3 mm. The flocculant is a mixed liquid of an inorganic polymer flocculant and a coagulant aid.

[0056] Specifically, after the moving slider 805 leaves the surface of the annular hoop 803, the liquid storage chamber 8032 is squeezed by the impact of the water flow, thereby increasing the diameter of the liquid outlet hole 8031, causing the mixed liquid inside the liquid storage chamber 8032 to flow out along with the water flow, thereby flocculating the scale particles suspended in the water flow into clumps. When cleaning, the cleaning personnel will briefly let the water flowing out of the water faucet 4 stand, and then check whether there are clumps in the water body to determine whether the scale on the surface of the No. 1 bubble net 806 and the No. 2 bubble net 807 is completely cleaned. At the same time, the suspended particles remaining inside can be settled, so that the scale inside the water faucet 4 is cleaned more completely. After the moving slider 805 moves up, the liquid outlet hole 8031 ​​is blocked by the moving slider 805, thereby preventing the outflow of the internal mixed liquid.

[0057] The use of coagulant aids can accelerate the flocculation rate of inorganic polymer flocculants and shorten the standing time.

[0058] See also Figure 1 The end of the water faucet 4 away from the tail water outlet part 9 is connected to the water supply metal hose 3, and the tail end surface of the water supply metal hose 3 is sleeved with a telescopic movable rod 2, and the length of the telescopic movable rod 2 is the same as the length of the water supply metal hose 3 in the retracted state. The tail end surface of the telescopic movable rod 2 is connected with a piston ring, and the outer side of the piston ring is sleeved with a fixed transmission rod 1, and the inner wall of the fixed transmission rod 1 is slidably connected to the piston ring.

[0059] Specifically, after pulling the water supply metal hose 3 out of the telescopic movable rod 2, the water outlet radius of the faucet 4 can be extended, and the wash basin and other parts of the washbasin inside the bathroom can be cleaned. By lengthening the telescopic movable rod 2, the water outlet height of the faucet 4 can be adjusted, so that the user can wash his hair and other washing operations at the washbasin.

[0060] The surface of the fixed transmission rod 1 is penetrated and connected with a symmetrically arranged cold water inlet 5 and a hot water inlet 6 , and the tail ends of the cold water inlet 5 and the hot water inlet 6 both extend into the interior of the water supply metal hose 3 .

[0061] Specifically, the cold water inlet 5 and the hot water inlet 6 respectively provide cold water and hot water for the bathroom faucet to meet different bathing temperature requirements.

[0062] See also Figure 2 A one-way plug 7 is installed on the inner wall of the water outlet faucet 4, and the one-way plug 7 is located above the cleaning and dredging unit 8.

[0063] Specifically, the use of the one-way plug 7 can ensure the one-way flow of water in the water tap 4 and reduce the backflow of external water.

[0064] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
