Automatic and manual toilet flushing device
A toilet flushing device comprises a valve assembly, an automatic control device and an manual control device. The automatic control device has a control circuit and causes flushing of the toilet upon an external signal. The manual control device allows manual flushing of the toilet. Thus bot automatic and manual flushing of the toilet are possible. A scent box provides disinfection and good odor.
The present invention relates to a toilet flushing device, particularly to a toilet flushing device which is both automatically and manually operated and provided with a filter grid and a scent box for filtering, disinfection, eliminating bad odor and adding scent.
BACKGROUND OF THE INVENTIONIn contemporary life, automatically and manually operated toilet flushing devices are indispensable for restoring a used toilet to a clean state.
Conventional toilet flushing devices are either manually or automatically operated, but not both. A manual toilet flushing device requires contact of a user's hand, implying risk of transmitting germs or infection. An automatic toilet flushing device does not work upon failure of power supply or other defects, so that the toilet remains unclean and unhygienic after use.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a toilet flushing device which is both automatically and manually operated.
It is a further object of the invention to provide a toilet flushing device which is connected to a flushed water pipe and provides desinfection, eliminating of bad odor and adding of scent.
Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the present invention.
As shown in
For convenient installation on the toilet bowl 12, the valve assembly 20, the automatic control device 50 and the manual control device 60 are housed in an outer case 15.
Referring to
For adjusting the length and the weight of the first magnet 33, an extension pin 331 is placed between the first magnet 33 and the silicon tip 39. The extension pin 331 is preferably made of PVC.

As shown in
The control circuit 53 works as follows: A. The sensor 51 receives an external signal for about 6 seconds. B. The coil 52, passed through by electric current, causes water to be released for 3 seconds. C. The sensor 51 having for 4 seconds received a continuous external signal, goes into a standby state. D. The sensor 51 receives no external signal. E. The coil 52, passed through by electric current, causes water to be released for 3-6 seconds.
As shown in
As further shown in
For assessing a need to use the manual control device 60, the automatic control device 50 has a light indicator 56, signalling a defect thereof or a lack of electrical power, so a user knows that the manual control device 60 has to be employed for flushing.

While preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
Claims
1. A toilet flushing device, operated both automatically and manually, comprising:
- a valve assembly, connected with a water supply apparatus and a toilet bowl;
- an automatic control device, which upon receiving of an external signal, causes said valve assembly to switch from a closed state to an open state to release flushing water into said toilet bowl; and
- a manual control device, which upon manual operation, causes said valve assembly to switch from a closed state to an open state to release flushing water into said toilet bowl.
2. The toilet flushing device of claim 1, wherein said valve assembly comprises:
- an inlet pipe, connected with said water supply apparatus;
- an outlet pipe, connected with said toilet bowl; and
- a valve, further comprising: a fixing tube, oriented in a vertical direction, having an inside with a pressure chamber, a rubber base plate, placed between said inlet pipe and said outlet pipe, having an inlet opening and an outlet opening, a first magnet, which is movable in a vertical movement inside said pressure chamber, with an amplitude of said vertical movement being determined by a length and a weight, further having a higher end leaning against a first spring, thereby being pressed downward, and a lower end carrying a silicon tip, which closes said outlet opening of said rubber base plate, a second magnet, mounted on an upper side of said fixing tube, and a second spring, pulling said second magnet away from said first magnet;
- wherein, in said closed state of said valve assembly, said silicon tip closes said water outlet opening, whereas in said opened state of said valve assembly, said automatic control device or said manual control device cause said second magnet to pull said first magnet upward, so that, for balancing pressure on upper and lower sides of said rubber base plate, said said rubber base plate rises, enabling outflow of flushing water.
3. The toilet flushing device of claim 2, wherein said automatic control device comprises: a sensor, receiving an external signal; a coil, mounted on an upper side of said fixing tube and generating a magnetic field when flown through by an electric current; a control circuit, connected with said sensor, said coil and an electrical power source; and a shifting assembly, having an upper plate, fastened to said coil, and a lower plate, which is made of magnetizable material and has a lower edge fastened to said second magnet; wherein, when said sensor receives an external signal, said control circuit causes electric current to flow through said coil, which in turn attracts said lower plate, so that said second magnet is brought close to said first magnet, causing water to flow out through said water outlet pipe.
4. The toilet flushing device of claim 3, wherein said electrical power source is a regular power source.
5. The toilet flushing device of claim 3, wherein said electrical power source is a solar panel.
6. The toilet flushing device of claim 3, wherein said control circuit works in steps as follows: A. receiving of an external signal by said sensor for about 6 seconds; B. flowing of electric current through said coil to release flushing water for 3 seconds; C. said sensor, after having for 4 seconds received a continuous external signal. going into a standby state; D. no external signal arriving at said sensor; E. flowing of electric current through said coil to release flushing water for 3-6 seconds.
7. The toilet flushing device of claim 3, wherein a connecting assembly connects said second magnet with said lower plate, having a first lobe, fastened to said second magnet, a second lobe, fastened to said lower plate, and a pin, passing through said first and second lobes.
8. The toilet flushing device of claim 2, wherein said manual control device comprises: a casing, housing said valve assembly; a rod, which passes through said casing, having an inner end, which is connected with said second magnet, and an outer end, which projects outward from said casing; and a third spring, connected with said casing and said rod at a certain location thereof; wherein, when said rod, by pressure on said outer end thereof, is manually pushed inward, said second magnet is moved close to said first magnet, causing outflow of water through said outlet pipe, and with no pressure on said outer end of said rod, said third spring presses said rod outward into an original position.
9. The toilet flushing device of claim 2, wherein of said first and second magnets, one is made of magnetic material and one is made of magnetizable material.
