Abstract
Description
Technical Field
[0001] This invention relates to the field of bathroom equipment technology, and in particular to an overhead shower head. Background Technology
[0002] Currently, during the process of supplying tap water to various water-using locations, various external factors can cause the tap water to contain various impurities. In some older residential areas, guesthouses, rental houses, and other water-using locations, due to inadequate pre-filtration measures (such as the absence of pre-filters), tap water containing impurities is directly supplied to overhead shower heads. Directly using tap water containing impurities for bathing can endanger the health of sensitive groups such as infants, young children, patients with eczema or dermatitis, and users with a history of rhinitis.
[0003] Therefore, a detachable filter cartridge is usually installed between the water supply ball head and the shower panel of the overhead shower head. After the water flows out of the water supply ball head, it quickly flows through the filter cartridge under the action of gravity and water pressure, and then flows into the shower panel, from which the shower water is sprayed. In this way, the contact time between the water flow and the filter medium in the filter cartridge is short and the contact is insufficient, resulting in a very limited filtration effect, and many impurities remain in the sprayed shower water. Summary of the Invention
[0004] To address the aforementioned shortcomings, the present invention aims to provide a top-spray shower head that solves the problem of poor water filtration effect caused by the design flaws in the filtration water path of existing top-spray shower heads.
[0005] To achieve this objective, the present invention adopts the following technical solution: A top-mounted shower head includes a shower panel, a long filter cartridge, and a water supply ball head. The long filter cartridge includes a long cylindrical shell, a long filter element cartridge, and a cap. The long cylindrical shell is horizontally disposed on the top surface of the shower panel from left to right along the length direction of the shower panel. The outlet of the long cylindrical shell is connected to the inner cavity of the shower panel, and the water supply ball head is hinged to the inlet of the long cylindrical shell. The cap and the right end opening of the long cylindrical shell are detachably connected, confining the long filter element inside the long cylindrical shell. The outer wall of the long filter element and the inner wall of the long cylindrical shell cooperate to form an inlet channel and an outlet channel. The inlet channel connects the inlet port and the inlet filter port at the left end of the long filter element, and the outlet channel connects the outlet port and the outlet filter port at the right end of the long filter element.
[0006] Furthermore, the outer wall of the long filter cartridge is provided with a radially spaced partition ring; the partition ring and the inner wall of the long cylindrical shell are tightly abutted against each other, and the left side of the partition ring, the outer wall of the long filter cartridge located on the left side of the partition ring and the inner wall of the long cylindrical shell together form the water inlet channel, and the right side of the partition ring, the outer wall of the long filter cartridge located on the right side of the partition ring and the inner wall of the long cylindrical shell together form the water outlet channel.
[0007] Furthermore, the long filter cartridge includes a housing and a media container; the inlet and outlet water outlets are respectively located at the left and right ends of the media container. The partition ring is provided along the right end of the shell opening. The shell is fitted onto the left part of the medium containing cylinder. The left end of the shell is provided with a shell water inlet corresponding to the water inlet filter. The left side of the partition ring, the outer wall of the shell, and the inner wall of the long cylindrical shell together form the water inlet cavity. The head of the cylinder cover and the right end of the long cylinder are detachably connected, and the tail of the cylinder cover is fitted onto the right end of the medium container cylinder; the right side of the partition ring, the right outer wall of the medium container cylinder and the inner wall of the long cylinder shell together form the water outlet channel.
[0008] Furthermore, a sleeve groove is provided at the tail end of the cylinder cover, and at least a pair of opposing cylinder cover limiting blocks are provided radially along the inner wall of the sleeve groove; the right end of the medium containing cylinder is sleeved in the sleeve groove, and the right end face of the medium containing cylinder abuts against the limiting block inside the cylinder cover. The sleeve groove has a cap outlet that connects to the water outlet channel between the limiting blocks inside the cap.
[0009] Furthermore, the medium container includes a through cylinder, a left end cap of the container, a left filter screen, a right end cap of the container, and a right filter screen; the left end cap of the container is disposed on the left opening of the through cylinder, and the left end cap of the container and the left opening of the through cylinder clamp and fix the left filter screen, the left filter screen serves as the water inlet, and the left end cap of the container has a left end cap water inlet corresponding to the left filter screen; The right end cap of the container is placed over the right opening of the tube. The right end cap of the container and the right opening of the tube clamp and fix the right filter screen. The right filter screen is used as the water outlet. The right end cap of the container has a right end cap water inlet corresponding to the right filter screen.
[0010] Furthermore, the inner bottom surface of the long cylindrical shell is provided with a cross-shaped protrusion and at least one lifting block. The cross-shaped protrusion is located in the center of the inner bottom surface of the long cylindrical shell, and the lifting block is located on the periphery of the cross-shaped protrusion. The height of the cross-shaped protrusion is greater than the height of the lifting block; the cross-shaped protrusion passes through the water inlet of the casing and the water inlet of the left end cover in sequence and abuts against the left filter screen; the lifting block abuts against the left end face of the casing.
[0011] Furthermore, the outer wall of the casing is provided with at least one water inlet channel partition along the length direction, and the side of the water inlet channel partition abuts against the inner wall of the long cylindrical shell.
[0012] Furthermore, the water inlet channel partition and the lifting block are staggered.
[0013] Furthermore, the outer wall of the tail end of the cylinder cover is provided with at least one water outlet channel partition along the length direction, and the side of the water outlet channel partition abuts against the inner wall of the long cylinder shell.
[0014] The technical solution provided by the present invention can include the following beneficial effects: First, the long cylindrical shell is laid flat on the top surface of the shower panel from left to right along the length direction of the shower panel, thereby extending the length of the filter cartridge and using more filter media to filter impurities in the bath water; then, the long filter cartridge is confined inside the long cylindrical shell by a detachable connection between the cylinder cover and the right end of the long cylindrical shell, thereby realizing the detachable installation of the long filter cartridge.
[0015] Based on the horizontal arrangement of the long filter cartridge, to ensure sufficient contact between the water flow and the filter medium for better filtration, an inlet and outlet channel are formed by the cooperation of the outer wall of the long filter cartridge and the inner wall of the long shell. The inlet channel connects the inlet to the left-hand inlet of the long filter cartridge, guiding the water flow from the water supply head to the left-hand inlet of the long filter cartridge. The outlet channel connects the outlet to the right-hand outlet of the long filter cartridge, guiding the water flow from the right-hand outlet of the long filter cartridge to the outlet and injecting it into the inner cavity of the shower panel, where it is sprayed as shower water. Therefore, when using the overhead shower, the water flow first fills the inlet channel, then horizontally fills the inside of the long filter cartridge, and finally fills the outlet channel. This ensures that all the shower water sprayed by the shower panel stays within the long filter cartridge for a long time and is in full contact, resulting in good filtration and almost no residual impurities in the sprayed shower water.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.
[0029] The following is combined Figures 1 to 8 This describes an embodiment of the overhead shower head.
[0030] A top-mounted shower head includes a shower panel 1, a long filter cylinder 2, and a water supply ball head 3. The long filter cylinder 2 includes a long cylindrical shell 21, a long filter element cylinder 22, and a cylinder cover 23. The long cylindrical shell 21 is horizontally arranged on the top surface of the shower panel 1 from left to right along the length direction of the shower panel 1. The water outlet 211 of the long cylindrical shell 21 is connected to the inner cavity of the shower panel 1, and the water supply ball head 3 is hinged to the water inlet 212 of the long cylindrical shell 21. The cylinder cover 23 and the right end of the long cylinder shell 21 are detachably connected, confining the long filter element cylinder 22 inside the long cylinder shell 21. The outer wall of the long filter element cylinder 22 and the inner wall of the long cylinder shell 21 cooperate to form the water inlet channel 4 and the water outlet channel 5. The water inlet channel 4 connects the water inlet 212 and the water inlet filter port 221 at the left end of the long filter element cylinder 22, and the water outlet channel 5 connects the water outlet 211 and the water outlet filter port 222 at the right end of the long filter element cylinder 22.
[0031] In a preferred embodiment of the overhead shower head proposed in this invention, such as... Figure 1 and 2 As shown, firstly, the long cylindrical shell 21 is laid flat on the top surface of the shower panel 1 from left to right along the length direction of the shower panel 1, thereby extending the length of the filter cartridge and allowing more filter media to be used to filter impurities in the bath water; then, the long filter cartridge 22 is confined inside the long cylindrical shell 21 by the detachable connection between the cylinder cover 23 and the right end of the long cylindrical shell 21, thus realizing the detachable installation of the long filter cartridge 22.
[0032] Based on the premise that the long filter cartridge 2 is laid flat, in order to allow the water flow to fully contact the filter medium and achieve a better filtration effect, the outer wall of the long filter cartridge 22 and the inner wall of the long shell 21 are used to form the water inlet channel 4 and the water outlet channel 5. The inlet channel 4 connects the inlet 212 to the inlet 221 at the left end of the long filter cartridge 22, guiding the water flow from the water supply ball head 3 to the inlet 221 at the left end of the long filter cartridge 22. The outlet channel 5 connects the outlet 211 to the outlet 222 at the right end of the long filter cartridge 22, guiding the water flow from the outlet 222 at the right end of the long filter cartridge 22 to the outlet 211, which is then injected into the inner cavity of the shower panel 1, where the shower panel 1 sprays bath water. Thus, when the overhead shower is used, the water flow first fills the inlet channel 4, then horizontally fills the inside of the long filter cartridge 22, and finally fills the outlet channel 5, thereby ensuring that all the bath water sprayed by the shower panel 1 stays in the long filter cartridge 22 for a long time and is fully in contact, resulting in good filtration and almost no residual impurities in the sprayed bath water.
[0033] Specifically, such as Figure 2 As shown, a partition ring 221 is provided radially around the outer wall of the long filter cartridge 22. The partition ring 221 and the inner wall of the long cylindrical shell 21 are tightly abutted to separate the cavities. The outer wall of the long filter cartridge 22 on the left side of the partition ring 221 and the inner wall of the long cylindrical shell 21 enclose the water inlet cavity 4. The outer wall of the long filter cartridge 22 on the right side of the partition ring 221 and the inner wall of the long cylindrical shell 21 enclose the water outlet cavity 5. Thus, within the limited internal space of the long cylindrical shell 21, the partition ring 221 fixes the gap between the inner wall of the long cylindrical shell 21 and the outer wall of the long filter cartridge 22, thereby separating and forming the water inlet cavity 4 and the water outlet cavity 5.
[0034] Furthermore, the long filter cartridge 22 includes a housing 224 and a media container 225; the inlet filter port 221 and the outlet filter port 222 are respectively located at the left and right ends of the media container 225. A partition ring 221 is provided along the right end of the shell opening of the shell 224. The shell 224 is fitted onto the left side of the medium container 225. The left end of the shell 224 is provided with a shell inlet 2241 corresponding to the water inlet filter 221. The left side of the partition ring 221, the outer wall of the shell 224 and the inner wall of the long shell 21 together form a water inlet cavity 4. The head of the cylinder cover 23 and the right end of the long cylinder shell 21 are detachably connected, and the tail of the cylinder cover 23 is fitted onto the right end of the medium container 225; the right side of the partition ring 221, the right outer wall of the medium container 225 and the inner wall of the long cylinder shell 21 together form the water outlet channel 5.
[0035] In this embodiment, as Figures 2 to 4As shown, based on the detachable connection between the head of the cover 23 and the right end of the long cylindrical shell 21 (for example, the right end of the long cylindrical shell 21 has a single-sided open slide, and the outer wall of the head of the cover 23 is provided with a slider that is screwed and limited within the slide to achieve a detachable connection), the tail of the cover 23 needs to be fitted onto the right end of the medium container 225 to limit the right side of the medium container 225. Therefore, a larger radial width space needs to be reserved on the right side of the partition ring 221 so that after the tail of the cover 23 fits onto the right end of the medium container 225, there is a gap between the outer wall of the tail of the cover 23 and the inner wall of the long cylindrical shell 21 to form the water outlet channel 5. Therefore, the left side of the medium container 225 needs to be fitted with an additional shell 224, and then the partition ring 221 is set along the right end of the shell 224 so that the radial width of the water outlet channel 5 is greater than the radial width of the water inlet channel 4.
[0036] Furthermore, a sleeve groove 231 is provided at the tail end of the cylinder cover 23, and at least one pair of oppositely arranged cylinder cover limiting blocks 232 are provided radially along the inner wall of the sleeve groove 231; the right end of the medium containing cylinder 225 is sleeved in the sleeve groove 231, and the right end face of the medium containing cylinder 225 abuts against the limiting block 231 inside the cylinder cover. The sleeve groove 231 has a cylinder cover outlet 233 that connects to the water outlet channel 5 between the inner limiting blocks 231 of the cylinder cover.
[0037] In this embodiment, as Figures 4 to 6 As shown, when the tail of the cylinder cover 23 is a closed sleeve groove 231, in order to ensure that the tail of the cylinder cover 23 is fitted onto the right end of the medium container cylinder 225, the bath water flowing out of the water outlet 222 at the right end of the medium container cylinder 225 can flow into the water outlet channel 5, the cylinder cover limiting block 232 is used to prevent the right end face of the medium container cylinder 225 from hitting the bottom of the sleeve groove 231 and being unable to discharge water. A cylinder cover water outlet 233 is opened between the limiting blocks 231 inside the cylinder cover to connect with the water outlet channel 5. The cylinder cover water outlet 233 is used to allow the bath water flowing out of the water outlet 222 to flow from the sleeve groove 231 to the water outlet channel 5.
[0038] Furthermore, the medium container 225 includes a through cylinder 2251, a left end cap 2252, a left filter screen 2253, a right end cap 2254, and a right filter screen 2255; the left end cap 2252 is placed over the left opening of the through cylinder 2251, and the left end cap 2252 and the left opening of the through cylinder 2251 clamp and fix the left filter screen 2253, which serves as a water inlet 221, and the left end cap 2252 has a left end cap water inlet 22521 corresponding to the left filter screen 2253; The right end cap 2254 of the container is placed on the right opening of the tube 2251. The right end cap 2254 of the container and the right opening of the tube 2251 clamp and fix the right filter screen 2255. The right filter screen 2255 is used as the water outlet 222. The right end cap 2254 of the container has a right end cap water inlet 22541 corresponding to the right filter screen 2255.
[0039] In this embodiment, as Figure 6 and 7 As shown, the left end cap 2252 of the container is attached (e.g., by a snap-fit connection) to the left opening of the tube 2251, and the right end cap 2254 of the container is attached (e.g., by a snap-fit connection) to the right opening of the tube 2251, forming a media container 225 that can be disassembled in both directions, which facilitates the replacement of the left filter screen 2253 and the right filter screen 2255 as well as the replacement of the filter media filled in the tube 2251.
[0040] It should be noted that the filter media can be composite fillers such as calcium sulfite particles, KDF copper-zinc alloy particles, and scale inhibitor filter media; among them, calcium sulfite can quickly decompose residual chlorine and chloramine in hot water and eliminate the irritating odor of disinfectant water; KDF copper-zinc alloy can remove soluble heavy metals and dissolved ferrous ions in water through oxidation-reduction reaction and inhibit bacterial growth in the filter cylinder 2251; scale inhibitor filter media can slowly release scale inhibitor components to form soluble complexes with calcium and magnesium ions, preventing calcium and magnesium ions from crystallizing to form calcium carbonate scale, and avoiding scale adhesion that clogs the left filter screen 2253, right filter screen 2255, and water outlet holes of the shower panel 1.
[0041] Furthermore, the inner bottom surface of the long cylindrical shell 21 is provided with a cross protrusion 213 and at least one lifting block 214. The cross protrusion 213 is located in the center of the inner bottom surface of the long cylindrical shell 21, and the lifting block 214 is located on the periphery of the cross protrusion 213. The height of the cross protrusion 213 is greater than the height of the lifting block 214; the cross protrusion 213 passes through the water inlet 2241 of the casing and the water inlet 22521 of the left end cover in sequence and abuts against the left filter screen 2253; the lifting block 214 abuts against the left end face of the casing 224.
[0042] In this embodiment, as Figure 7 and 8 As shown, the lifting block 214 is used to prevent the bottom surface of the inner cylinder of the outer shell 224 and the long cylinder shell 21 from sticking together, which would prevent water from flowing out of the water inlet filter 221. The cross protrusion 213 is used to support the left filter screen 2253.
[0043] Furthermore, such as Figure 3 As shown, the outer wall of the casing 224 is provided with at least one water inlet channel partition 2242 along the length direction. The side of the water inlet channel partition 2242 abuts against the inner wall of the long cylindrical shell 21. The water inlet channel partition 2242 is used to ensure the radial width of the water inlet channel 4.
[0044] Furthermore, considering that if the inlet channel partition 2242 and the lifting block 214 overlap, it will close the inlet channel 4, therefore... Figure 3 and 8 As shown, the inlet channel partition 2242 and the lifting block 214 need to be staggered. For example, if the lifting block 214 is an oblique strip from the outside of the cross protrusion 213 to the inner wall of the long cylindrical shell 21, then the lifting block 214 will not completely overlap with the end of the inlet channel partition 2242.
[0045] Furthermore, such as Figure 3 As shown, the outer wall of the tail of the cylinder cover 23 is provided with at least one water outlet channel partition 234 along the length direction. The side of the water outlet channel partition 234 abuts against the inner wall of the long cylinder shell 21. The water outlet channel partition 234 is used to ensure the radial width of the water outlet channel 5.
