The foot cups 6 are fixed to the bottom of the first seat 5 and the bottom of the second seat 10, and casters (not shown) are fixed for movement, and the casters are preferably universal wheels. The first seat 5 and the second seat 10 are hollow structures so as to install a driving mechanism of the stool 1 therein, which will be described in the following paragraphs.

The stool 1 is placed on the top of the first and second seat bodies and supported by the first and second seat bodies, and the mouth of the stool 1 is butted with the mouth of the toilet bowl 9.

In one embodiment, the left side of the stool 1 is further locked and fixed with a left armrest 2, the right side of the stool is further locked and fixed with a right armrest 12, and a user can hold two arms on the two armrests after sitting on the stool 1.

The driving mechanisms of the stool 1 are arranged in the first seat body 5 and the second seat body 10, and the driving mechanisms in the two seat bodies move synchronously to drive the stool 1 to lift and incline. The driving mechanism of the stool 1 will be described below by taking the first seat 5 as an example.

Referring to fig. 2 and 3, a sliding plate 13 is fixed to a side wall of the interior of the first seat 5, two first rollers 14 and two second rollers 15 are respectively fixed to the sliding plate 13 through shafts, the two first rollers 14 are distributed in an arc shape, the two second rollers 15 are also distributed in an arc shape, and an arc track is formed between the two first rollers 14 and the two second rollers 15. An arc-shaped guide rail 18 is fixed in the arc-shaped track, and the arc-shaped guide rail 18 is in sliding fit with the arc-shaped track and can lift along the arc-shaped track. Furthermore, grooves are formed in the circumferential surfaces of the first roller and the second roller along the circumferential direction, the inner edge of the arc-shaped guide rail 18 is embedded with the grooves in the circumferential surface of the first roller 14, and the outer edge of the arc-shaped guide rail 18 is embedded with the grooves in the circumferential surface of the second roller 15, so that the arc-shaped guide rail 18 and the rollers can be prevented from being separated. It is understood that the same effect can be achieved by providing grooves on the inner and outer edges of the arc-shaped guide rail 18 and fitting the first and second rollers 14 and 15 into the grooves of the arc-shaped guide rail 18. Preferably, the second roller 15 is an eccentric roller, so that the gap between the arc-shaped guide rail 18 and the arc-shaped track can be adjusted by adjusting the eccentric roller, thereby ensuring the stable lifting of the stool 1.

The position of the arc-shaped guide rail 18 close to the bottom end is hinged with a second connecting rod 19, the other end of the second connecting rod 19 is hinged with a first connecting rod 16, the other end of the first connecting rod 16 is hinged with a connecting rod support of the first seat body 5, the body part of the electric push rod 17 is hinged with the bottom of the first seat body 5, and the power output end of the electric push rod 17 is hinged with the middle part of the first connecting rod 16.

The top end of the arc-shaped guide rail 18 is locked and fixed with the stool 1, and the fixing mode can be clamping, welding, screw connection and the like. The lifting motion of the arc-shaped guide rail 18 drives the stool 1 to lift synchronously. The arc-shaped guide rail 18 is matched with the arc-shaped track, so that the stool 1 is inclined towards the front of the toilet bowl in the lifting process, or the stool 1 is lifted and moved towards the front upper part of the toilet bowl.

In fig. 2, the electric push bar 17 is in a retracted state in which the arc-shaped guide rail 18 and the stool 1 are in an unraised state. In fig. 3, the electric push rod 17 is in an extended state in which the arc-shaped guide rail 18 and the stool 1 are in a raised state. Wherein, the stroke of the electric push rod 17 is smaller than the lifting stroke of the arc-shaped guide rail 18 and the stool 1.

As can be seen from the above, by providing the first and second connecting rods, the electric push rod 17 can realize a relatively large lifting stroke and a relatively large inclination angle of the stool 1 through a relatively short stroke. The lifting stroke and the inclination angle of the bench 1 are larger the more the hinge point of the electric push rod 17 and the first connecting rod 16 is lifted.

Referring to fig. 2 and 3 again, the controller is hermetically installed in the control box 22, the control box 22 is locked and fixed in the first seat 5, a wire hole is formed in the rear side wall of the first seat 5, and a waterproof rubber sleeve 21 is installed in the wire hole. The top of the first base 5 is provided with a through hole for the arc-shaped guide rail 18 to pass through, the through hole is provided with a waterproof felt 20, and the joint part of the main body part of the first base 5 and the cover plate is provided with waterproof glue. In addition, the electric push rod 17 is selected to have a protection grade above IP54, and the lifting control switch 3 and the alarm switch 11 are sleeved with waterproof rubber sleeves. So that the whole water-proof performance of the auxiliary equipment of the toilet bowl is good.

The use method of the toilet bowl auxiliary equipment comprises the following steps: after the user presses the lifting control switch 3 on the handrail, the controller controls the two paths of electric push rods 17 to simultaneously extend out or retract, and the arc-shaped guide rails 18 are driven to lift according to the arc-shaped tracks, so that the sitting stool 1 is driven to lift, and the function of assisting the user in bending to sit down or standing up is realized. After the lifting control switch 3 is released, the electric push rod 17 stops rotating, and the stool 1 can stop at any position, and has a self-locking function. An upper travel limit switch and a lower travel limit switch are installed in the first seat body and/or the second seat body, and the arc-shaped guide rail 18 stops moving when moving to the travel limit switches, so that the safety of users and equipment is protected. When the user presses the alarm switch 11 on the armrest, a signal is generated to make a buzzer mounted in the control box 22 generate an alarm sound.

And an encoder is arranged at the motor end of the electric push rod 17 and is electrically connected with the controller, and the detected rotation angle is fed back to the controller to realize the closed-loop control of the rotation speed. The encoder may for example employ a combination of a grating disc and a photo-sensor.

In one embodiment, the electric push rod 17 has a reduction ratio of 1 to 29, and a push rod lead of 1.75 mm/rotation.

As another embodiment, the reduction ratio of the electric putter 17 is also preferably not less than 1: preferably, the lead is less than 2 mm/revolution 20.

A controller block diagram of an embodiment is shown in fig. 4.

In one embodiment, the controller is powered by a dual power wide voltage input. One path of power supply is 24V direct current power supply input, and a switching power supply is preferred. The other power supply is a battery input, preferably a 12V or 18V battery. When two paths of power supplies are simultaneously connected to the control box, the direct-current power supply can be automatically identified and preferentially used for supplying power. Fig. 5 shows a specific power supply circuit.

As shown in fig. 5, the connector U1 is connected to a switching power supply, the connector U2 is connected to a battery, an output terminal of the switching power supply is connected to an anode of a diode D1, a cathode of the diode D1 is connected to a voltage bus, and an anode of the diode D1 is further connected to a resistor R1 and an indicator light LED1 to ground; the output end of the battery is connected with the anode of the diode D4, the cathode of the diode D4 and the anode of the diode D2 are connected with two ends of a normally closed contact of the relay K1, the cathode of the diode D2 is connected with a voltage bus, the anode of the diode D2 is also connected with the resistor R2 and the indicator light LED2 to the ground, and the coil of the relay K1 is connected with the output end of the switching power supply. When the switch power supply has input, the switch power supply supplies power to the voltage bus, and the coil of the relay K1 is electrified, the normally closed contact enters a disconnection state, and the battery is automatically disconnected from the voltage bus. When the switch power supply is not input, the coil of the relay K1 loses power, the normally closed contact returns to a closed state, and the battery supplies power to the voltage bus.

In one embodiment, the auxiliary device further comprises an under-voltage detection circuit, an over-current detection circuit and a short-circuit protection circuit.

The undervoltage detection circuit is electrically connected with the voltage bus, and can protect the over-discharge of the battery. A voltage dividing resistor is connected to a voltage bus, an ADC (analog to digital converter) port of a single chip microcomputer (controller) is connected to a voltage dividing position, and voltage at the voltage dividing position is sampled. The single chip microcomputer obtains input voltage feedback in real time, a current voltage value is calculated, when the feedback voltage is lower than a set under-voltage value, the single chip microcomputer controls to close a load, and the electric quantity lamp is only normally on by the red lamp beads.

The overvoltage detection circuit can protect the load from being damaged by overvoltage. The detection principle is the same as that of undervoltage detection, and when the fed-back voltage is higher than the set overvoltage voltage, the load is controlled to be closed by the single chip microcomputer.

The over-current detection circuit can protect the load from being damaged by exceeding the maximum current. The main principle is as follows: the current is converted into voltage and then compared with the reference voltage to judge the maximum current. And a low-resistance sampling resistor is connected in series in the voltage bus. When the maximum current flows through the sampling resistor, the resistor is unchanged, and the voltage on the sampling resistor increases with the current. In order to reduce the bus impedance, the resistance value of the sampling resistor is very low, so the voltage at two ends of the sampling resistor is also very low. In order to obtain a recognizable voltage, the sampled voltage needs to be amplified by an operational amplifier. At the maximum current, the voltage amplified by the operational amplifier is the overcurrent voltage. The amplified over-current voltage can be adjusted by adjusting the multiple of the operational amplifier. In order to reduce interference, the output voltage of an LDO (low dropout regulator) is used as a reference voltage, and the amplification factor of an amplifier is adjusted to make the over-current voltage slightly larger than the LDO voltage. Then, the two paths of voltages are connected into a comparator, when the voltages do not flow, the amplified voltage is lower than the reference voltage of the LDO, and the comparator outputs high level; when overcurrent occurs, the amplification voltage is higher than the LDO reference voltage, and the comparator outputs low level. And the singlechip receives the low level and controls to close the load. Fig. 6 shows an overcurrent detection circuit, in which the resistor R56 is a sampling resistor, the operational amplifier U9A and its peripheral components C24, C26, R50, R57 and R58 form an amplifying circuit, the chip U8A is a comparator, the chip U7 is an LDO, and the comparator U8A is provided with a reference voltage. The voltage at the two ends of the sampling resistor R56 is amplified by the amplifying circuit and then is input into the comparator U8A, the comparator U8A compares the voltage with the reference voltage provided by the U7 to output low level or high level, and when the comparator U8A outputs the low level, overcurrent is indicated.

The short-circuit protection circuit can protect against damage due to short-circuits. The principle is the same as that of the over-current detection circuit.

In an embodiment, this auxiliary assembly further includes the temperature-sensing ware, and the temperature-sensing ware sets up in the highest region of toilet bowl auxiliary assembly's temperature, and the temperature feedback of collection is to the singlechip, and the singlechip discerns the temperature and is higher than when setting up the temperature, closes the load, protects, can avoid because the continuous operation is too of a specified duration, leads to the temperature rise too high, causes the potential safety hazard.

In order to eliminate the deviation, in an embodiment, the auxiliary device further includes a zero position sensor, specifically, the zero position sensor is disposed at the top and the bottom of the electric push rod 17, the optional zero position sensor includes but is not limited to a photoelectric switch, a hall switch, a micro switch, a proximity switch, and the like, when the electric push rod extends to a maximum position or retracts, the zero position sensor is triggered to output a signal, and after the single chip identifies the signal of the zero position sensor, an error generated by each movement of the arc-shaped guide rail 18 is cleared.
