[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 3A shower hose comprises a filter device 1 and a tube body 2, wherein the filter device 1 comprises a shell 11 and a filter element 12, wherein the filter element 12 is arranged in the shell 11, one end of the tube body 2 is connected to the shower head, and the other end is connected to the shell 11; a threaded structure is arranged at one end of the shell 11 away from the tube body 2.

[0024] From the above description, it can be seen that the beneficial effects of the utility model are: by integrating the tube body 2 with the filter device 1, it is possible to achieve water filtering when the shower is running, wherein the filter element 12 can be adjusted to a sterilization filter element 12, an aromatherapy filter element 12, etc. according to needs on the basis of filtering impurities and foreign matter, thereby improving the safety and reliability of shower water; the shell 11 is arranged at the end of the tube body 2, which can avoid increasing the mass of the shower head and improve the convenience of taking and placing the shower; the shell 11 also serves as a connecting structure between the tube body 2 and the water outlet device, and is designed with an internal thread for quick connection with a faucet or other water outlet device.

[0025] Furthermore, a through hole 111 is provided at one end of the shell 11 close to the tube body 2 , and one end of the tube body 2 passes through the through hole 111 and is provided with a docking joint 21 , wherein the diameter of the docking joint 21 is greater than the diameter of the through hole 111 .

[0026] As can be seen from the above description, the tube body 2 passes through the through hole 111 so that one end of the tube body 2 is placed in the housing 11 to match the filter element 12 ; the diameter design of the joint 21 can prevent the tube body 2 from falling out of the housing 11 .

[0027] Furthermore, one end of the tube body 2 is movably disposed in the housing 11 and abuts against the filter element 12 .

[0028] It can be seen from the above description that, through the pressure between the filter element 12 and the tube body 2 and the abutment between the docking joint 21 of the tube body 2 and the through hole 111 due to the diameter design, the tube body 2 and the shell 11 can be fixed while the filter element 12 is fixed; and the movable setting of the tube body 2 makes it possible to push the tube body 2 toward the inside of the shell 11 to push out the filter element 12 when disassembling and replacing the filter element 12, so as to facilitate the replacement of the filter element 12.

[0029] Furthermore, the shell 11 includes an installation shell 112 and a fixing cover 113, the lower end of the installation shell 112 is connected to the tube body 2, the upper end of the installation shell 112 is provided with a fixing port 114, the fixing port 114 is provided with an external thread, and the fixing cover 113 is threadedly connected to the fixing port 114; the fixing cover 113 is provided with an internal thread at one end away from the fixing port 114.

[0030] As can be seen from the above description, the detachable arrangement of the housing 11 is realized by the cooperation between the fixing cover 113 and the mounting housing 112. When the filter element 12 needs to be replaced, the fixing cover 113 can be unscrewed to expose the fixing port 114, and the filter element 12 can be taken out from the fixing port 114 at this time; the fixing cover 113 is used to close the fixing port 114 to prevent the filter element 12 from falling out, and is also designed as an internal thread for connecting the water outlet device; at the same time, the external thread design on the fixing port 114 and the internal thread design of the fixing cover 113 can ensure that when a single thread structure is connected and matched, the other thread structure will not be affected and released, that is, after the mounting housing 112 and the fixing cover 113 are tightened in the first direction, when the combined overall structure is tightened and connected to the water outlet device in the first direction, the former cooperation will not produce a change of release.

[0031] Furthermore, the filter element 12 includes a core body 121, a water passage is provided inside the core body 121, a water inlet hole is provided on the circumference of the core body 121, a water outlet hole is provided at the lower end of the core body 121, and the water inlet hole, water passage, water outlet hole and through hole 111 are connected.

[0032] From the above description, it can be seen that when water passes through the filter element 12, the water flows into the water passage inside the core body 121 through the water inlet holes on the circumference of the core body 121, during which the water flow is filtered by the core body 121; then the water flows into the water outlet holes through the water passage and finally enters the tube body 2; especially for the tubular structure of the tube body 2, in order to match it without being abrupt, the core body 121 is also usually tubular, and the tubular structure has a larger circumference, which is suitable for large-area water passing and filtering. The water inlet hole design on the circumference can effectively increase the water passing and filtering area.

[0033] Furthermore, the filter element 12 further includes an upper fixing member 122 , which is connected to the upper end of the core body 121 and blocks the upper end surface of the core body 121 .

[0034] It can be known from the above description that the connection between the upper fixing member 122 and the upper end of the core body 121 can prevent water from directly entering the upper end surface of the core body 121 and preventing water from entering from the surrounding surface to achieve filtering.

[0035] Furthermore, a protrusion 124 is provided on the upper end surface of the upper fixing member 122 , and the protrusion 124 abuts against the inner wall of the fixing cover 113 .

[0036] It can be seen from the above description that, through the design of the protrusion 124 on the upper fixing member 122 abutting against the inner wall of the fixing cover 113, the water flow space between the fixing cover 113 and the upper fixing member 122 can be increased, the water flow rate can be improved, and it can be avoided that after the fixing cover 113 is installed, the upper end surface of the upper fixing member 122 is directly pressed, which causes the water flow gap between the upper fixing member 122 and the fixing cover 113 to be reduced, thereby affecting the water flow rate.

[0037] Furthermore, a slow flow groove 125 is provided in the middle of the upper fixing member 122 .

[0038] From the above description, it can be seen that through the design of the slow flow groove 125 in the middle of the upper fixing part 122, when water flows in from the fixing cover 113, the water flows into the slow flow groove 125, reducing the flow rate, and then overflows evenly around the slow flow groove 125 and then flows evenly to the peripheral surface of the core 121, thereby improving the filtration efficiency and filtration effect.

[0039] Furthermore, a step structure is protruded from the inner wall of one end of the shell 11 connected to the tube body 2 , and the step structure encloses the inner wall of the through hole 111 ; an inclined guide surface is provided at the edge of one end of the step structure close to the filter element 12 .

[0040] From the above description, it can be seen that the design of the step structure enables the filter element 12 to be inserted and fixed in the through hole 111 of the shell 11 in an inserted manner; and the inclined guide surface on the step structure can guide the filter element 12 when it is inserted, so that it falls accurately into the through hole 111 and remains coaxial with the through hole 111 and the shell 11.

[0041] Furthermore, a filter screen 115 is provided at one end of the shell 11 away from the tube body 2 .

[0042] It can be seen from the above description that the filter screen 115 designed at the end of the shell 11 away from the tube body 2 can be used as a primary filtering structure to filter large particle impurities, and then further filtered through the filter element 12.

[0043] Embodiment 1:

[0044] Application scenario: In the filtration design of bathroom shower water, there is a design in the prior art that filters the shower water to output high-quality spray water, but this type of design mostly sets the filtering structure on the shower head or externally on the shower and its hose, and does not use it as a shower component. The former shower head design easily makes the shower too heavy and inconvenient to take and put, while the latter external treatment causes the inconvenience of equipment connection, layout and replacement of the filtering structure.

A slow flow groove 125 is provided in the middle of the upper fixing member 122. A protrusion 124 is provided on the upper end surface of the upper fixing member 122, and the protrusion 124 abuts against the inner wall of the fixing cover 113. Specifically, a sealing gasket is provided between the upper fixing piece 122 and the fixing cover 113. On the one hand, the sealing gasket ensures that after the fixing cover 113 is locked into the fixing port 114, the upper fixing piece 122 can be pressed to fix the filter element 12, thereby playing a role in adjusting and adapting the size and process errors of the upper fixing piece 122. On the other hand, the gap between the fixing cover 113 and the fixing port 114 can be sealed by its side.

[0048] Specifically, the inner wall of the end of the housing 11 connected to the tube body 2 protrudes with a step structure, and the step structure encloses the inner wall of the through hole 111; the edge of the step structure close to the filter element 12 is provided with an inclined guide surface.
