Description
Technical Field
The utility model relates to a control switch, especially intelligent closestool's novel knob.
Background
The intelligent closestool knob on the market is mainly installed in the side of closestool at present, utilize pressing and the rotation of knob to realize corresponding operation, the knob is rotatory or rely on the suction of two pairs of magnets to produce the restoring force that resets after pressing, these two pairs of magnets produce the sensing signal with two hall element on the circuit board mutual induction simultaneously, microcontroller on the circuit board mainly accepts two hall element and is located the signal of telecommunication of the switch that dabs of knob pivot bottom to through the function of communication interface output button value realization button. The power supply of the knob mainly depends on the 5V power supply of the closestool main controller.
The disadvantages of this design are: after the knob is rotated and loosened, the knob is easy to vibrate by utilizing the handle in the resetting process of the magnet, although the vibration can be reduced by enhancing the magnetism of the magnet and increasing the attraction force, the rotating rotary force of the knob is increased, and the hand feeling of a user is influenced; the use of two pairs of strong magnets results in higher costs.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of above-mentioned background art, provide a novel knob of intelligent closestool, this knob should have the use and feel good, the cost of manufacture low characteristics.
The utility model provides a technical scheme is:
the novel knob for the intelligent closestool comprises a rotating part which is rotatably positioned on a shell seat through a rotating shaft; a small magnet is embedded on the rotating part, a circuit board with two Hall elements is installed on the shell seat, and the installation positions of the two Hall elements are close to two extreme positions of the small magnet when the small magnet rotates along with the circuit board; the method is characterized in that: still install the spring on the novel knob, the both ends of spring apply force respectively in rotating piece and shell seat to the messenger returns pivoted power with the rotation piece that the pivot links to each other.
The spring is a spiral spring which is sleeved on the rotating shaft in a penetrating way, and two ends of the spiral spring are respectively provided with a bending end which is bent towards the outer diameter direction and is embedded on the rotating piece in a clamping way; the shell seat is also provided with a stop block which protrudes towards the rotating part and is inserted between the two bent ends of the spiral spring, so that the rotating part bears the resistance of the spiral spring while being rotated, and the mounting position of the rotating part is positioned at the same time.
The rotating piece is provided with an arc shifting block protruding towards the shell seat, and two bending ends of the spiral spring are respectively clamped at two ends of the arc shifting block so as to realize energy storage of the spiral spring.
And the circuit board is also provided with a touch switch corresponding to the bottom end of the rotating shaft.
The shell seat is fixed on the toilet control panel through a locking ring.
The utility model has the advantages that: the utility model discloses a mode that coil spring holds energy gives pivot automatic re-setting's kinetic energy, and required revolving force is great when not only having solved prior art rotation, the use is felt poor not enough, has reduced the cost of manufacture moreover by a wide margin.
Drawings
Fig. 1 is a schematic perspective view of the present invention (showing the position relationship between the small magnet on the rotating member and the two hall elements on the housing).
Fig. 2 is a second schematic perspective view (showing the installation position of the coil spring) of the present invention.
Fig. 3 is a third schematic view of the three-dimensional structure of the present invention (showing the position relationship between the bottom end of the rotating shaft and the tact switch).
Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
Fig. 1 shows that the utility model discloses contain pivot 7, the rotation piece 1 (being knob handle) that is connected with pivot 7, shell seat 3, install first hall switching device 4 and second hall switching device 6 on the circuit board, install little magnet 5 on the rotation piece (preferably adopt a 9 x 2.5 x 1.65 rectangle little magnet to respond to two hall elements), wear the cover in epaxial spring 2 of pivot (preferably coil spring), install the circuit board that just has microcontroller in shell seat lower part (prior art, omit in the figure).
As can be seen from fig. 2: the spiral spring is sleeved on the rotating shaft in a penetrating mode, bending ends bent towards the outer diameter direction are arranged at two ends of the spiral spring respectively, the rotating piece is provided with a shifting block 1-1 protruding towards the shell seat direction (parallel to the axis direction of the rotating shaft), and two bending ends (a first bending end 2-1 and a second bending end 2-2) of the spiral spring are respectively clamped and embedded at two ends of the shifting block after rotating for a certain angle around the axis of the rotating shaft, so that the energy storage of the spiral spring in advance is achieved. The shell seat is also provided with a stop block 3-1 protruding towards the direction of the rotating piece (parallel to the axial direction of the rotating shaft), and the stop block is inserted between two bent ends of the spiral spring (a radial gap is kept between the stop block and the shifting block) so that the rotating piece can bear the resistance of the spiral spring while being rotated; and the mounting position (relative angle with the shell seat) of the rotating part can be accurately positioned.
When the rotating piece rotates clockwise, the small magnet 5 on the rotating piece 1 also rotates along with the rotation of the rotating piece 1; when the small magnet 5 rotates to the front of the second Hall switch device 6, an induction signal is generated and input to the microcontroller. In a similar way, when the rotating part 1 rotates anticlockwise, the small magnet 5 on the rotating part 1 also rotates along with the rotation of the rotating part 1; when the small magnet 5 rotates to the front of the first hall switching device 4, an induction signal is generated and is output to the microcontroller. When the rotating member 1 is released, the rotating member 1 will automatically return to the position before rotation due to the elastic force of the spring 2 caught on the rotating member 1. Compare in current mode and rely on two pairs of magnet to come automatic re-setting, this kind of mode easy operation, with low costs, and can not reciprocate after reseing and vibrate, feel effectual. A tact switch 9 opposite to the bottom of the rotating shaft 7 is also arranged on the circuit board, and the bottom end of the rotating shaft 7 is contacted with the tact switch. When the rotating member 1 is pressed down, the rotating shaft 7 connected with the rotating member 1 correspondingly slides downwards through the shaft hole on the inner shell 3; when the rotating shaft 7 slides downwards to the bottom of the stroke of the tact switch (the stroke of the tact switch is 0.3mm), the tact switch generates a trigger signal and inputs the trigger signal to the microcontroller, and the microcontroller outputs a corresponding key value according to the trigger signal. When the hand leaves the rotating part, the rotating part is driven to axially move to return to the original position by the recovery elastic force of the tact switch, the rotating shaft 7 and the tact switch return to the original position, and the microcontroller keeps a standby state.
The figure also shows: a locking ring 8 used for fixing the knob on a control panel (the control panel is positioned on the side surface of the whole closestool), and an external thread matched with the locking ring is manufactured on the shell seat.
