Description

Technical Field

[0001] The utility model relates to the technical field of sanitary wares, and particularly to a descaling shower head. Background Art

[0002] After the shower head is used daily, scale is likely to adhere to the water outlet. If the water outlet is not cleaned for a long time, the scale will completely block the water outlet, thus affecting the normal use of the shower head. Although there are already shower heads with descaling functions, there are still many deficiencies in their structures, which cause inconvenience to users. Traditional shower heads, although having descaling functions, are not perfect in structure, complex and cumbersome in design, and cannot completely solve the problem.

[0003] In the case of an automatic descaling shower head and a method for self-descaling of a shower head with the application number 201610585060.3, a driving member drives a transmission member to rotate and drives a descaling plate to move. Such a concave-convex abutting fit is used to drive the up-and-down movement of the descaling plate, and a reset device is required to correspondingly drive the descaling structure back to the initial position, resulting in a cumbersome configuration of internal structural components of the shower head and unable to achieve simplicity and high efficiency.

[0004] In the case of a shower head with a descaling mechanism with the application number 202311563427.8, a piston and a spring member are correspondingly provided on the descaling needle plate. While switching the water outlet, hydraulic power is used for descaling to achieve automatic descaling. And the descaling needle plate with a spring is directly pressed up and down by the water pressure of the water outlet. On the one hand, it is limited by the factor of water pressure magnitude, and on the other hand, the structure still cannot be made simple and is difficult to meet the production and manufacturing requirements.

[0029] Embodiment

[0030] Combined with Figures 1 to 7 , this embodiment provides a descaling shower head, which includes a shower head body 1, a water outlet face cover 2, and a descaling plate 3. The shower head body 1 is provided with a water inlet 4, the water outlet face cover 2 is provided with a water outlet, and the front surface of the descaling plate 3 is provided with descaling needles 7 corresponding to the water outlet. The water outlet face cover 2 is movably arranged on the shower head body 1, the descaling plate 3 is arranged in the cavity of the shower head body 1 and can move relative to the water outlet face cover 2. A connecting member 8 is provided on the back surface of the descaling plate 3, and a guiding member 9 for hanging and guiding the connecting member 8 is correspondingly provided in the cavity of the shower head body 1. After the water outlet face cover 2 rotates, it can drive the connecting member 8 to move relative to the guiding member 9 to control the relative position of the descaling plate 3 and the water outlet face cover 2, and correspondingly guide the descaling needles 7 of the descaling plate 3 to insert into or away from the water outlet.

[0031] For the above descaling shower head, by switching the movement of the water outlet face cover 2, the descaling needles 7 can automatically insert into one of the water outlets (such as the first water outlet 5 described below) to remove the accumulated water scale, without the need for the user to manually disassemble and clean, greatly improving the cleaning efficiency. Regular automatic descaling can prevent the water outlet from being blocked due to the accumulation of water scale, thereby extending the service life of the shower head.

[0032] A connecting member 8 is provided on the back surface of the descaling plate 3, a guiding member 9 is correspondingly provided in the cavity of the shower head body 1, and after the water outlet face cover 2 rotates, it can drive the connecting member 8 to move relative to the guiding member 9 to control the relative position of the descaling plate 3 on the water outlet face cover 2, quickly realizing the descaling operation and avoiding water discharge. Through the hanging and guiding of the guiding member 9 on the connecting member 8, the descaling plate 3 is directly driven to move up and down, without the need to additionally provide a reset structure, greatly simplifying the effective driving of the descaling plate 3, and the hanging and guiding method makes the driving conduction more efficient and stable.

[0033] Such as Figures 2 to 4As shown, in this embodiment, the water outlet cover 2 can rotate relative to the shower head body 1. The shown connecting member 8 can follow the rotation of the water outlet cover 2 and is controlled by the guiding member 9 to drive the descaling plate 3 to move relatively in the up and down directions. Among them, when the water outlet cover 2 rotates, it correspondingly drives the connecting member 8 and the descaling plate 3 to rotate. At the same time, after the rotating connecting member 8 is hung and guided by the guiding member 9, it can further move vertically up and down, so as to move upward until the descaling plate 3 is separated from the water outlet cover 2 to allow the water outlet to be used for water discharge. Correspondingly, when the water outlet cover 2 rotates back to the initial position, it correspondingly drives the connecting member 8 to move downward until the descaling needle 7 of the descaling plate 3 is inserted into and engaged with the water outlet of the water outlet cover 2. At this time, the descaling operation is carried out and the water outlet is blocked from discharging water.

[0034] Specifically, the guiding member 9 has a low position height that limits the connecting member 8 to the first position, a middle position height that limits the connecting member 8 to the second position, and a high position height that limits the connecting member 8 to the third position. The water outlet cover 2 is at least provided with a first water outlet 5 and a second water outlet 6, and when in the low position height, the descaling needle 7 is inserted into the first water outlet 5. It should be mentioned that the above three heights are directly formed on the guiding member 9, and each height corresponds to a relative position state of the connecting member 8 and its descaling plate 3. In the low position height, at this time the descaling plate 3 is at the lower limit position to abut against the water outlet cover 2 so that the descaling needle 7 is inserted into the first water outlet 5. In the middle position height, at this time the descaling plate 3 moves relatively upward to the middle position (located between the water outlet cover 2 and the following water distribution plate 14). In the high position height, at this time the descaling plate 3 is at the upper limit position (abutting against the following water distribution plate 14) to be away from the water outlet cover 2.

[0035] In this embodiment, the connecting member 8 is configured as a convex column 10 integrally formed on the back surface of the descaling plate 3, and the guiding member 9 is configured as a engaging portion 12 provided on the shower head body 1 and extending obliquely to form a guide rail 11. The convex column 10 is provided with a bayonet 13 that is engaged and adapted with the guide rail 11 of the engaging portion 12. Preferably, the bayonet 13 is formed with an outwardly expanding notch on one side to facilitate quick sliding and engagement on the guide rail 11. By hanging the bayonet 13 of the convex column 10 on the guide rail 11 of the engaging portion 12, the bayonet 13 is slidably arranged on the guide rail 11, so that the convex column 10 can move correspondingly in the horizontal oblique direction to drive the descaling plate 3 to move up and down.

[0036] Specifically, the engaging portion 12 is formed as a convex block on the inner wall of the shower head body 1, and the guide rail 11 is configured as an inclined rib. The low position height and the high position height are correspondingly formed at both ends of the guide rail 11. Specifically, the guide rail 11 protrudes from the side wall of the convex block, and the guide rail 11 has at least a gentle slope in the middle section.

[0037] In other embodiments, the clamping part 12 is in the shape of a strip groove and is obliquely disposed on the inner wall of the shower body 1, and the low height and the high height are correspondingly formed on the two ends of the clamping part 12. The lower end of the clamping part 12 is defined by the guide rail 11, and the strip-shaped clamping part 12 forms a corresponding moving path for the protruding column 10, and the descaling plate 3 is hung on the guide rail 11 of the clamping part 12 through the bayonet 13 of the protruding column 10, so as to realize the support connection of the descaling plate 3 in the shower body 1. In addition, the two ends of the clamping part 12 correspondingly limit the protruding column 10 from continuing to move upward or downward.

[0038] Preferably, at least two bosses 10 are arranged opposite to the descaling plate 3, and a clamping portion 12 is provided to cooperate with the bosses 10. The two bosses 10 are arranged on the back edge of the descaling plate 3 to achieve a more stable hanging connection, and the descaling plate 3 can be driven and guided efficiently.

[0039] like Figures 5 to 7 As shown, in this embodiment, the descaling shower head further includes a water separation plate 14 disposed in the shower body 1. The descaling plate 3 is movably accommodated between the water separation plate 14 and the water outlet surface cover 2 and allows the connecting member 8 to pass through the water separation plate 14. The water separation plate 14 is used to control the water flow of the water inlet 4 to input the first water outlet 5 and the second water outlet 6, or the first water outlet 5. Preferably, the water separation plate 14 and the descaling plate 3 cooperate with each other to realize the selective water outlet of each water outlet.

[0040] In this embodiment, the water outlet cover 2 is provided with an operating member 15 for switching the panel rotation. Preferably, the operating member 15 is configured as a toggle structure formed on the water outlet cover 2, so that the user can directly toggle the water outlet cover 2 to rotate. When the operating member 15 is in the initial position, the descaling plate 3 is located between the water outlet cover 2 and the water diversion plate 14 (the connecting member 8 is limited to the second position), and water is discharged to the first water outlet 5 and the second water outlet 6. The operating member 15 rotates clockwise along the initial position until the descaling plate 3 is switched to move until the descaling needle 7 is inserted into the first water outlet 5 (the connecting member 8 is limited to the first position), and the water is switched to the second water outlet 6. The operating member 15 rotates counterclockwise along the initial position until the descaling needle 7 is away from the first water outlet 5 (the connecting member 8 is limited to the third position), and the water is switched to the first water outlet 5.

[0041] Furthermore, the water separation plate 14 is installed and configured on the water outlet surface cover 2, and the two are relatively linked and coordinated. Thus, the water separation plate 14 cooperates with the descaling plate 3 to turn the water outlet on and off. When the descaling plate 3 abuts against the water outlet surface cover 2, the first water outlet 5 is blocked by the descaling needle 7, and the descaling plate 3 is separated from the water separation plate 14. The water corresponding to the water input into the water separation plate 14 along the water inlet 4 can only be transmitted to the second water outlet 6, and the water outlet from the second water outlet 6 is implemented. When the descaling plate 3 is centrally arranged between the water outlet surface cover 2 and the water separation plate 14, the water input into the water separation plate 14 along the water inlet 4 can be transmitted to the second water outlet 6 and the first water outlet 5, and the first water outlet 5 and the second water outlet 6 are implemented to discharge water together. When the descaling plate 3 abuts against the water separation plate 14, the descaling plate 3 cooperates with the water separation plate 14 to block the water flow entering the second water outlet 6, and the water outlet from the first water outlet 5 is implemented.

[0042] It should be mentioned that the first water outlet 5 is configured to outlet shower water, and the second water outlet 6 is correspondingly configured to outlet granular water, thereby realizing the multifunctional switching water outlet of the shower.

[0043] like Figure 5 and Figure 7 As shown, in this embodiment, the descaling shower head also includes a positioning pin 16 for elastically abutting against the water diversion plate 14, and the water diversion plate 14 can rotate with the water outlet cover 2. At least two matching positions are correspondingly provided on the water diversion plate 14, and the matching positions and the positioning pin 16 are mutually aligned to define the position of the descaling plate 3 on the water outlet cover 2. Among them, at least one of the matching positions can define the position where the descaling plate 3 abuts against the water outlet cover 2, so as to realize the use of granular water outflow from the second water outlet 6. At least another matching position can define the position where the descaling plate 3 abuts against the water diversion plate 14, so as to realize the use of shower water outflow from the first water outlet 5. Furthermore, between the two matching positions, the descaling plate 3 is located at any position between the water outlet cover 2 and the water diversion plate 14, so as to realize the use of shower water and granular water together.

[0044] like Figure 5 As shown, in this embodiment, a plurality of cat's eye pads 17 are correspondingly arranged on the water separation plate 14, and the cat's eye pads 17 are configured as a water separation leather cup structure. In addition, the protrusion 10 of the descaling plate 3 is penetrated by the V-shaped ring 18 of the water separation plate 14, and the sealing performance of the water separation plate 14 is improved through the V-shaped ring 18.

[0045] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
