Because the amount of the mixed liquid used for filling the pipeline inside the product for descaling is very small each time, the procedure can be circulated for a plurality of times until the descaling agent saturated solution inside the cavity at the upper part of the descaling device body is completely diluted by the inlet water. Or the user can regularly remove the scale for a plurality of times in the subsequent product using process under the condition of additionally installing the scale removing particles for one time, so that the aim of conveniently using the scale removing particles for a plurality of times by additionally installing the scale removing particles for one time by the user is fulfilled.

An isolation screen 16 is placed at the bottom of the descaling agent cavity 12 of the shell 14 to isolate the descaling particles from blocking the saturated solution outlet pipe formed at the bottom of the shell between the periphery of the shell water inlet pipe 11 and the inner cavity wall of the shell 14. The end 15 is preferably a round end, the excircle of the end is preferably provided with a spiral structure and a fixing buckle so as to be detachably connected with the descaling device body fixing seat 2, the inner hole of the round end is separated into an inner layer space and an outer layer space, the hollow part is a shell water inlet pipe 11, and the periphery of the water inlet pipe is communicated with a clearance descaling saturated solution outlet 22 formed between the inner cavity wall of the shell 14.

The descaling device body fixing seat 2 and the solenoid valve fixing seat 4 are integrated into a whole through a locking structure to save space, and the descaling device body fixing seat 2 is provided with an inner spiral groove matched with a saturated solution outlet end of a body shell and a fixing structure to fix the body shell 14. The inside of the fixed seat 2 of the descaling device body comprises a water inlet cavity 23 and a solution outlet cavity 24 which have different diameters, and the water inlet cavity 23 and the solution outlet cavity 24 are respectively in sealing fit with the shell water inlet pipe 11 at the outer lower end of the descaling device body 1 and the water inlet pipe sealing ring 111 and the end sealing ring 151 on the end head 15 to form two separated water inlet cavities 23 and solution outlet cavities 24.

The electromagnetic switch valve 3 is a switch for opening and closing the descaling device, when the electromagnetic switch valve is opened for descaling initialization, the opening time of the electromagnetic switch valve is controlled, so that a certain volume of product water flow enters a shell water inlet pipe in the middle of the inner cavity of the outer shell of the descaling device body, then enters the inner cavity of the shell, is mixed with descaling particles sealed in the inner cavity of the outer shell, and forms saturated dissolution. When the descaling function is formally started, the electromagnetic switch valve is opened again, the saturated solution in the shell of the descaling device body is extruded out from the output port at the bottom of the shell by the new inflow water flow, and is mixed with the product water flow in a certain proportion after passing through the external one-way valve, and flows through the subsequent components along with the product water flow for descaling, and when the electromagnetic switch valve is closed, the descaling function is stopped.

The electromagnetic valve fixing seat 4 is provided with an electromagnetic switch valve fixing seat water inlet 41 and a descaling mixed liquid water outlet 42, a structure similar to a three-way valve is integrated inside the electromagnetic switch valve fixing seat 4, and a part of water flow of the electromagnetic switch valve fixing seat water inlet 41 enters the descaling device body 1 through the body fixing seat water inlet 21 under the control of the electromagnetic switch valve 3. The descaling saturated solution flowing through the one-way valve 5 after flowing out of the descaling device body 1 is mixed with the water flow of the water inlet 41 of the electromagnetic switch valve fixing seat in the three-way structure space arranged in the electromagnetic switch valve fixing seat 4, then flows out of the descaling mixed liquid outlet 42 and flows through the subsequent parts along with the water flow of the product to descale. Of course, if space permits, a separate three-way valve may be provided around the periphery of the device so that the product influent mixes with the saturated descaling solution and then flows through the subsequent components.

When the product descales, the mixed descaling liquid flow can flow through each pipeline inside the product and flow out from the nozzle, and the water supply of the product is stopped when the mixed descaling liquid is filled in each pipeline inside the product for a certain time, so that the mixed descaling liquid stays in the pipeline inside the product for a certain time, and the mixed descaling liquid fully reacts with the scale integrated inside the pipeline to decompose the scale. Because the amount of the mixed liquid used for filling the pipeline inside the product for descaling is very small each time, the procedure can be circulated for a plurality of times until the descaling agent saturated solution inside the cavity at the upper part of the descaling device body is completely diluted by the inlet water. Or the user can regularly remove the scale for a plurality of times in the subsequent product using process under the condition of additionally installing the scale removing particles for one time, so that the aim of conveniently using the scale removing particles for a plurality of times by additionally installing the scale removing particles for one time by the user is fulfilled.

When the descaling is finished, the product is restarted to feed water, on one hand, the water scale residue after the inner pipeline of the product is decomposed by the new water supply of the product can be flushed out through the nozzle holes, on the other hand, the residual fixed particle descaling agent in the descaling device body can be completely dissolved, and the inner cavity of the shell of the descaling device body is cleaned and dried.

When the descaling particles stored in the descaling agent cavity 12 are exhausted, the user can take the descaling device body 1 out of the descaling device body fixing seat 2 by rotating and upwards, open the outer cover and add the descaling particles again so as to start a new descaling round.

According to the invention, through the independent descaling device which can be conveniently dismounted from the product, the problem that the descaling of internal parts cannot be realized in the existing electronic toilet without an internal water tank and a water pump is solved, and a user can conveniently dismount the descaling device body from the product, add descaling particles and reassemble the descaling device body on the product for use.
