spraying a first linear water flow to the anus from the rectum flushing nozzle, modifying the relative position between the rectum flushing nozzle and the user's anus so that the first linear water flow aims at the anus; spraying the anus with a second linear water flow from the rectum flushing nozzle to pass through the anus and into the rectum; spraying continuously the second linear water flow and stopping spray of the second linear water flow when the user has a desire to defecate, then the user discharges the substance in the rectum. ## Claims ### Claim 1 A method for emptying a rectum by using a retractable human body flushing means of an electronic sanitary appliance which is arranged on a toilet, the electronic sanitary appliance comprises a main body unit, a toilet seat, and a retractable human body flushing means which extends out to locate underneath of the toilet seat and retracts into the main body unit, the human body flushing means comprising a nozzle head with one rectum flushing nozzle for producing one first straight aiming water column for aiming at an anus of a user and for producing one second straight rectum-entering water column for entering into the rectum for a distance, the method comprising: 1) extending out the rectum flushing nozzle of the nozzle head so that it locates underneath of the anus of a user who is seated on the toilet seat; 2) generating the first straight aiming water column by the rectum flushing nozzle, spraying it to the anus, and adjusting the position between the rectum flushing nozzle and the user's anus so that the first straight aiming water column aims at the anus and the first straight aiming water column aligns with the anus; 3) then spraying the anus with a straight water column, which does not enter into the anus and is formed by increasing the pressure of the first straight aiming water column, so as to relax the muscle of the anus; 4) spraying the anus with the second straight rectum-entering water column from the rectum flushing nozzle which is formed by increasing relative water-pressure of the straight water column in step 3), so that the second straight rectum-entering water column passes through the anus in a straight line and enters into the rectum; 5) spraying continuously the second straight rectum-entering water column and stopping spray of the second straight water column when the user has a desire to defecate, so that the user evacuates substance in the rectum, wherein the rectum flushing nozzle is provided with a bore having a conical shape so that its diameter gradually reduces from its inlet diameter to its outlet diameter. ### Claim 2 (depends on 1) The method for emptying the rectum by using an electronic sanitary appliance according to claim 1, wherein the first straight aiming water column is sprayed under a relative pressure in the range from 0.03 MPa to 0.055 MPa, and the second straight rectum-entering water column is sprayed under a relative pressure in the range from 0.07 MPa to 0.14 MPa. ### Claim 3 (depends on 2) The method for emptying the rectum by using an electronic sanitary appliance according to claim 2, wherein the second straight rectum-entering water column is sprayed under a relative pressure which increases in a stepwise way. ### Claim 4 (depends on 3) The method for emptying the rectum by using an electronic sanitary appliance according to claim 3, wherein the relative pressure difference of the second straight rectum-entering water column between adjacent two relative pressures is in the range from 0.01 MPa to 0.06 MPa. ### Claim 5 (depends on 1) The method for emptying the rectum by using an electronic sanitary appliance according to claim 1, wherein in step 5), after evacuating substance in the rectum, the user continues to sit on the toilet seat for a certain time and evacuates at least one time. ### Claim 6 (depends on 1) The method for emptying the rectum by using an electronic sanitary appliance according to claim 1, wherein the distance between the rectum flushing nozzle and the anus is in the range from 5 mm to 150 mm, the outlet diameter of the rectum flushing nozzle is in the range from 0.8 mm to 2.5 mm, and a ratio between the outlet diameter and the length of the nozzle bore is in the range of 1:3 to 1:20. ### Claim 7 (depends on 1) The method for emptying the rectum by using an electronic sanitary appliance according to claim 1, wherein the temperature of the first straight aiming water column and the second straight rectum-entering water column is in the range from 25° C. to 41° C. ### Claim 8 A method for emptying a rectum by using a retractable human body flushing means of an electronic sanitary appliance, wherein the electronic sanitary appliance comprises a main body unit, a toilet seat, and a retractable human body flushing means which extends out to locate below the toilet seat and retracts into the main body unit, the human body flushing means comprising a nozzle head with one rectum flushing nozzle for producing one first straight aiming water column for aiming at an anus of a user and for producing one second straight rectum-entering water column for entering into the rectum for a distance, wherein the method comprises: 1) extending out the rectum flushing nozzle of the nozzle head so that it locates below the anus of a user sitting on the toilet seat; 2) generating the first straight aiming water column by the rectum flushing nozzle, spraying it to the anus, and adjusting the position between the rectum flushing nozzle and the user's anus so that the first straight aiming water column aims at the anus and the first straight aiming water column aligns with the anus; 3) then spraying the anus with a straight water column, which does not enter into the anus and is formed by increasing the pressure of the first straight aiming water column, so as to relax the muscle of the anus; 4) spraying the anus with the second straight rectum-entering water column from the rectum flushing nozzle which is formed by increasing relative water-pressure of the straight water column in step 3), so that the second straight rectum-entering water column passes through the anus in a straight line and enters into the rectum; 5) spraying the anus with the second straight rectum-entering water column and stopping spray of the second straight water column when the user has a desire to defecate, so that the user evacuates substance in the rectum, wherein the rectum flushing nozzle is provided with a bore having a conical shape so that its diameter gradually reduces from its inlet diameter to its outlet diameter. ### Claim 9 (depends on 8) The method for emptying the rectum by using an electronic sanitary appliance according to claim 8, wherein the first straight aiming water column is sprayed under a relative pressure in the range from 0.03 MPa to 0.055 MPa, and the second straight rectum-entering water column is sprayed under a relative pressure in the range from 0.07 MPa to 0.14 MPa. ### Claim 10 (depends on 8) The method for emptying the rectum by using an electronic sanitary appliance according to claim 8, wherein the distance between the rectum flushing nozzle and the anus is in the range from 5 mm to 150 mm, the outlet diameter of the rectum flushing nozzle is in the range from 0.8 mm to 2.5 mm, and a ratio between the outlet diameter and length of the nozzle bore is in the range of 1:3-1:20. ### Claim 11 (depends on 8) The method for emptying the rectum by using an electronic sanitary appliance according to claim 8, wherein the second straight rectum-entering water column of step 4) is sprayed for at least 2 seconds. ### Claim 12 (depends on 11) The method for emptying the rectum by using an electronic sanitary appliance according to claim 11, wherein the second straight rectum-entering water column of step 4) is sprayed for between 30 seconds and 70 seconds.
