Description

Technical Field

[0001] The present invention relates to the technical field of shower heads, and more particularly to a water purification shower head for a solar water heater. Background Art

[0002] A shower head refers to a shower nozzle, also known as a shower head or a shower nozzle, which sprays water through multiple small holes to facilitate uniform rinsing of the body during bathing. It is usually used in conjunction with a shower and is connected to a solar water heater through a tubular bracket, so that the water in the solar water heater is mixed with cold water and then sprayed out from the shower head.

[0003] In the prior art, a Chinese patent with the application number CN201610572977.X discloses a shower head, which includes a handle and a water purification component. The water purification component is arranged inside the handle and includes a filter element and a sterilization filter element. The filter element is used to filter out impurities in the water. The sterilization filter element is arranged in the water outlet direction of the filter element and is connected to the filter element. The sterilization filter element is used to filter out bacteria in the water. The water purification component is used to make the water flow through the filter element and then into the sterilization filter element. The filter element can filter out large particle substances such as sediment, rust, and colloid in the water, can also filter out free chlorine in the water, and can also remove some organic substances in the water, such as chloroform and carbon tetrachloride, and can also remove some heavy metals in the water, such as lead, mercury, cadmium, and arsenic. The sterilization filter element can be used to filter out bacteria in the water. In this way, the water flowing out of the shower head is clean and hygienic, ensuring the safety of the user's bathing water.

[0004] Again, in the prior art, a Chinese patent with the application number CN201810697194.3 discloses a household water purification shower head, which includes a shower head body. The shower head body is provided with a nozzle, the nozzle is connected with a bent pipe, the bent pipe is provided with an internal thread port, the internal thread port is connected with a handle water pipe, the handle water pipe is provided with an external thread port and an internal thread port one, the handle water pipe is sleeved with a handle protection sleeve, the nozzle is provided with spraying fine holes and spraying round holes, the nozzle is provided with a detachable spraying panel, and the detachable spraying panel is provided with a detaching pull head. By connecting the bent pipe and the handle water pipe through the internal thread port and the external thread port, the shower head can be connected. Through the internal thread port one, it can be connected with the thread port of an external water pipe. The water is conveyed to the handle water pipe through the external water pipe, and the water is conveyed to the nozzle through the bent pipe and then sprayed out.

[0005] For another example, in the prior art, a Chinese patent with the application number CN202220511207.5 discloses a water purification shower head, which includes a housing. The upper end of the housing has a water inlet, and the housing has an inner cavity. Inside the housing, a movable plate, a flow conversion plate, and a filter cartridge are installed in sequence from top to bottom. A filter element is installed inside the filter cartridge. The flow conversion plate divides the inner cavity into an upper cavity and a lower cavity. The upper cavity is communicated with the water inlet. The flow conversion plate has a first through hole and a second through hole. The upper cavity is communicated with the first through hole or the second through hole. The first through hole is communicated with the lower cavity, and the second through hole is communicated with the filter cartridge. A blocking member for blocking the first through hole or the second through hole is installed on the movable plate. A button for connecting the movable plate and driving the movable plate to rotate is installed on the outer side of the upper end of the housing. The bottom of the housing has a raw water outlet hole and a purified water outlet hole. The raw water outlet hole is communicated with the lower cavity, and the purified water outlet hole is communicated with the filter cartridge.

[0006] Combined with the above materials, it can be seen that in the prior art, in order to prevent the water outlet holes of the shower head from being blocked, a water purification component can be added inside to filter impurities in the water. However, in the actual use process, the filtering component is generally a filter screen or filler, which has an upper limit of service time. After reaching the limit, it needs to be replaced or disassembled and cleaned due to blockage. Replacing increases costs, and disassembling and cleaning is time-consuming and laborious. Summary of the Invention

[0007] The purpose of the present invention is to provide a water purification shower head for a solar water heater to solve the problem that the filtering component needs to be replaced or disassembled and cleaned regularly as mentioned in the above background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A water purification shower head for a solar water heater, including a support frame made of a metal pipe. A shower head body is installed at the top of the support frame. An outlet baffle is fixedly installed below the shower head body by a fixing bolt. A water purifier is fixedly installed between the support frame and the shower head body. The water purifier is set as a hollow columnar structure; A commutator is installed inside the water purifier. The commutator is integrally set as a hollow spherical structure. Two filter plates are fixedly installed on the outer surface of the commutator. A rotating handle extending to the outside of the water purifier is fixedly installed on the side of the commutator. A through hole for switching the water inlet direction is opened on the side of the commutator. A connecting pipe is fixedly installed at the middle position of the upper surface of the shower head body. Telescopic mechanisms are provided at both the connecting pipe and the top of the support frame; A circulation box is fixedly installed on the upper surface of the shower head body. The circulation box is located behind the water purifier. Two storage cylinders are fixedly installed inside the circulation box. Block-shaped cleaning materials are contained inside the storage cylinders. The cleaning materials are acidic. Using acidity can better dissolve water scale and achieve the best cleaning effect.

[0009] Preferably, a sewage pipe communicated with it is fixedly installed on the side of the water purifier, and the sewage pipe is located below the commutator.

[0010] Preferably, the commutator rotates in conformity with the arc-shaped structure of the inner wall of the water purifier, and the maximum rotation angle of the commutator is 90°.

[0011] Preferably, the telescopic mechanism includes a first sleeve installed at the top end of the support frame and a second sleeve installed at the top end of the communicating pipe, and the first sleeve and the adsorption magnet are magnetically adsorbed to each other, and the adsorption magnet is fixedly installed outside the through hole. By adsorbing the first sleeve with the adsorption magnet, the first sleeve is closer to the surface of the commutator, achieving a better sealing effect.

[0012] Preferably, the first sleeve and the support frame form a nested sliding structure, a first spring is fixedly installed between the outer part of the first sleeve and the support frame, and a sealing ring is fixedly installed on the lower surface of the first sleeve. The sealing ring is used to further improve the sealing effect.

[0013] Preferably, the second sleeve and the communicating pipe form a nested sliding structure, and a second spring is fixedly installed between the outer part of the second sleeve and the communicating pipe.

[0014] Preferably, a first connecting pipe and a second connecting pipe are fixedly installed at the upper end of the circulation box, and the tops of the first connecting pipe and the second connecting pipe are both communicated with the inside of the water purifier, and the upper ends of the first connecting pipe and the second connecting pipe are higher than the commutator. The first connecting pipe and the second connecting pipe are used to enable the water in the water purifier to circulate in the circulation box, so as to be mixed with the cleaning material.

[0015] Preferably, a connecting shaft is fixedly installed at the rear end of the commutator, and the connecting shaft penetrates into the circulation box, and a sealing block is fixedly installed on the outer part of the connecting shaft.

[0016] Preferably, the sealing block is made of soft rubber material, the position of the sealing block corresponds to the bottoms of the first connecting pipe and the second connecting pipe, and a one-way valve is fixedly installed on the outer part of the second connecting pipe.

[0017] Preferably, a stirring plate is rotatably installed inside the shower head main body, the stirring plate corresponds to the position of the communicating pipe, and an axial flow fan blade is fixedly installed at the rotating position of the stirring plate. The axial flow fan blade is located inside the communicating pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The water purifying shower head for the solar water heater adopts a novel structural design, and the specific content is as follows: 1. The water of the solar water heater flows into the water purifier through the support frame (at this time, the commutator is in a horizontal position, that is, the two filter plates are located on the upper and lower sides). After being filtered by the filter plates, the water enters the inside of the shower head main body through the connecting pipe and then sprays out, avoiding the blockage of the holes in the water outlet baffle of the shower head main body by impurities in the water. During this process, the arc-shaped structure on the inner wall of the water purifier seals the through holes; Further, this device is set as a structure that does not require replacement and cleaning. When it is necessary to clean the filter plates, the commutator is rotated 90° by turning the handle. At this time, the two filter plates rotate to the left and right sides, and the through holes rotate to the position corresponding to the top of the support frame, so that the water in the support frame enters the inside of the commutator through the through holes and then discharges from the position of the filter plates. At this time, the water flow direction is opposite to the filtering direction, so as to achieve the purpose of flushing the filter plates and cleaning the impurities accumulated on the surface of the filter plates. At this time, the lower surface of the commutator blocks the connecting pipe to prevent sewage from entering the inside of the shower head; Furthermore, when cleaning the filter screen, the first sleeve is adsorbed downward to the position close to the surface of the commutator by the adsorption effect of the adsorption magnet, so as to achieve a better sealing effect. At the same time, under the elastic pushing action of the second spring, the second sleeve moves upward to the position close to the outer surface of the commutator, improving the sealing effect between the connecting pipe and the commutator.

[0019] 2. When cleaning the filter plates, the commutator drives the sealing block to rotate 90° synchronously through the connecting shaft, so that the sealing block disengages from the sealing effect on the first connecting pipe and the second connecting pipe. At this time, the water in the water purifier enters the inside of the circulation box through the first connecting pipe, and then is discharged into the water purifier from the second connecting pipe after being mixed with the acidic cleaning material. After dissolving the dirt with acid, the cleaning effect is improved.

[0020] 3. When the water enters the shower head main body through the connecting pipe, the axial flow blades are driven to rotate under the action of the water flow, so that the axial flow blades drive the stirring plate to rotate. The stirring plate stirs the incoming water flow to improve the mixing uniformity of cold and hot water and avoid the situation of sudden cold and sudden heat during showering.

Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Please refer to Figures 1 - 3 , in order to achieve the purpose of purifying the water of the solar water heater in this embodiment, the following technical solutions are provided, specifically disclosed: a support frame 1 made of a metal pipe, a shower head body 2 is installed at the top of the support frame 1, a water outlet baffle 3 is fixedly installed below the shower head body 2 by a fixing bolt 301, and a water purifier 4 is fixedly installed between the support frame 1 and the shower head body 2. The water purifier 4 is set as a hollow columnar structure; a commutator 5 is installed inside the water purifier 4, and the commutator 5 is integrally set as a hollow spherical structure, and two filter plates 6 are fixedly installed on the outer surface of the commutator 5. A stirring plate 25 is rotatably installed inside the shower head body 2, and the stirring plate 25 corresponds to the position of the connecting pipe 13, and an axial flow fan blade 26 is fixedly installed at the rotating position of the stirring plate 25. The axial flow fan blade 26 is located inside the connecting pipe 13.

[0025] Connect the support frame 1 to the solar water heater. When taking a shower, turn on the switch, and the water in the solar water heater is mixed with tap water and enters the inside of the support frame 1. Finally, it sprays out from the inside of the shower head body 2 at the top of the support frame 1. At this time, the water flow is dispersed by the water outlet baffle 3 below the shower head body 2. Before the shower water is discharged from the shower head body 2, it first enters the water purifier 4. At this time, the water is filtered by the filter plate 6 in the commutator 5 (the commutator 5 is in a horizontal position, that is, the two filter plates 6 are located on the upper and lower sides). The filtered water enters the shower head body 2 through the connecting pipe 13. Under the action of the water flow, the axial flow fan blade 26 inside the connecting pipe 13 is driven to rotate, so that the axial flow fan blade 26 drives the stirring plate 25 to rotate. The stirring plate 25 is used to stir the water flow to improve the mixing uniformity of cold and hot water.

[0026] Embodiment 2: Please refer to Figures 4 - 8 , in order to achieve the purpose of realizing the filter component without replacement and disassembly in this embodiment, the following technical solutions are provided. Specifically disclosed are: a rotating handle 7 is fixedly installed on the side of the commutator 5 and extends outside the water purifier 4, and a through hole 8 for switching the water inlet direction is opened on the side of the commutator 5. A connecting pipe 13 is fixedly installed at the middle position of the upper surface of the shower head body 2, and telescopic mechanisms are provided at both the connecting pipe 13 and the top end of the support frame 1. A sewage discharge pipe 16 communicated therewith is fixedly installed on the side of the water purifier 4, and the sewage discharge pipe 16 is located below the commutator 5. The commutator 5 is in rotational fit with the arc-shaped structure on the inner wall of the water purifier 4, and the maximum rotation angle of the commutator 5 is 90°. The telescopic mechanism includes a first sleeve 10 installed at the top end of the support frame 1 and a second sleeve 14 installed at the top end of the connecting pipe 13. The first sleeve 10 and the adsorption magnet 9 are magnetically adsorbed to each other, and the adsorption magnet 9 is fixedly installed outside the through hole 8. The first sleeve 10 and the support frame 1 form a nested sliding structure, and a first spring 12 is fixedly installed between the outside of the first sleeve 10 and the support frame 1. The second sleeve 14 and the connecting pipe 13 form a nested sliding structure, and a second spring 15 is fixedly installed between the outside of the second sleeve 14 and the connecting pipe 13. And a sealing ring 11 is fixedly installed on the lower surface of the first sleeve 10.

[0027] When the filter plate 6 needs to be cleaned after being used for a period of time, first rotate the commutator 5 inside the water purifier 4 by turning the handle 7, so that the commutator 5 rotates 90°. At this time, the two filter plates 6 follow the commutator 5 and rotate to the side, and at the same time, the through holes 8 rotate to the position above the top end of the support frame 1. Under the magnetic adsorption of the adsorption magnet 9, the first sleeve 10 at the top end of the support frame 1 is adsorbed downward, so that the sealing ring 11 on the lower surface of the first sleeve 10 is close to the outer surface of the commutator 5, thereby improving the sealing effect between the support frame 1 and the commutator 5. At the same time, the non-perforated side of the commutator 5 rotates to the lower position corresponding to the communicating pipe 13, and under the elastic pushing action of the second spring 15, the second sleeve 14 is moved upward, so that the second sleeve 14 is close to the surface of the commutator 5 to achieve the purpose of sealing. Then, the water entering the water purifier 4 in the support frame 1 enters the commutator 5 through the through holes 8, and then is discharged from the positions of the filter plates 6 on the left and right sides to achieve the purpose of backwashing the filter plate 6. After that, since the position of the communicating pipe 13 is sealed, the flushing sewage will be discharged from the sewage pipe 16.

[0028] Embodiment 3: Please refer to Figures 1 - 3 , in order to achieve the purpose of improving the cleaning effect in this embodiment, the following technical solutions are provided, and specifically disclosed: A circulation box 17 is fixedly installed on the upper surface of the shower head body 2, and the circulation box 17 is located behind the water purifier 4. Two storage cylinders 23 are fixedly installed inside the circulation box 17. A block-shaped cleaning material 24 is contained inside the storage cylinder 23, and the cleaning material 24 is acidic. A first connecting pipe 18 and a second connecting pipe 19 are fixedly installed at the upper end of the circulation box 17, and the tops of the first connecting pipe 18 and the second connecting pipe 19 are both communicated with the inside of the water purifier 4. The upper ends of the first connecting pipe 18 and the second connecting pipe 19 are higher than the commutator 5. A connecting shaft 21 is fixedly installed at the rear end of the commutator 5, and the connecting shaft 21 penetrates into the circulation box 17. A sealing block 22 is fixedly installed outside the connecting shaft 21. The sealing block 22 is made of soft rubber material, and the position of the sealing block 22 corresponds to the bottoms of the first connecting pipe 18 and the second connecting pipe 19. A one-way valve 20 is fixedly installed outside the second connecting pipe 19.

[0029] When turning the handle 7 to drive the commutator 5 to rotate (that is, when the filter plate 6 needs to be backwashed), the connecting shaft 21 at the rear side of the commutator 5 is used to drive the sealing block 22 to rotate synchronously, so that the sealing block 22 is separated from the sealing between the first connecting pipe 18 and the second connecting pipe 19 (the sealing block 22 seals the first connecting pipe 18 and the second connecting pipe 19 during normal shower use). At this time, the water in the water purifier 4 enters the circulation box 17 through the first connecting pipe 18. The entering water dissolves part of the cleaning material 24, and the water with the cleaning material 24 is discharged back into the water purifier 4 through the second connecting pipe 19 under the action of water pressure. Finally, the acid of the cleaning material 24 is used to dissolve the water scale to achieve a better cleaning effect.
