Description

The automatic jettison gear of a kind of flush toilet

The utility model relates to the automatic jettison gear of a kind of flush toilet.

The flushing of flush toilet at present all is to realize that by the switch that adopts hand to go to spur or push jettison gear there is following shortcoming in this mode: (1) is not easy to old, weak, sick, residual, children's use; (2) easily cause uncivil phenomenon and behavior (mainly finger does not wash); (3) if adopt regularly, quantitatively flushing, then be prone to or wash untimely, or waste water.

The purpose of this utility model is to provide a kind of flush toilet automatic jettison gear, and this device can be realized flush toilet flushing automatically after an action of the bowels, and is both convenient, healthy, using water wisely again.

For achieving the above object, the solution that the utility model adopts is: it is by shell, tooth bar, gear, the band arm gear, compression spring and extension spring are formed, wherein shell is made up of two symmetrical coverboards, there be symmetrical being used to that three holes of gear and band arm gear are installed respectively on two symmetrical coverboards, there are two to be circular hole in these three holes, another hole is to be the arcuate socket at center with one of them circular hole, gear is two, a gear is installed in a circular hole place by axle, another gear can be installed in the arcuate socket place up or down by axle, be meshing with each other between two gears, the band arm gear is installed in another circular hole place by axle, its arm passes the groove on the shell and stretches out outside the housing, there are several to be used for installing and regulating rope on the arm, the aperture of extension spring position, one end of extension spring is fixed on aperture place on the arm of being with arm gear, the other end is connected on the hook of shell, tooth bar can be installed in a side of shell up or down by location structure, with the corresponding shell in its upper end on have a hole, stretch out outside the housing upper end of tooth bar, there is a hole its inside, the first half of compression spring is installed in the hole, and the lower end is placed on the circular arc platform.

Boss before and after above-mentioned location structure is meant on the tooth bar on the two sides, and with shell that boss matches on groove.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is an appearance assumption diagram of the present utility model.

State diagram when Fig. 2 does not work for the utility model.

Fig. 3 is the working state figure of the utility model when human body is sat down.

Fig. 4 plays immediately working state figure for the utility model at human body.

Fig. 5 is mounting structure figure of the present utility model.

From Fig. 1, Fig. 2 as can be known, the utility model is by shell 1, gear 2, gear 3, band arm gear 4, tooth bar 5, extension spring 6 and compression spring 7 are formed, shell 1 is formed by connecting by screw by two symmetrical coverboards, on its two symmetrical coverboards, three symmetrical holes (as shown in Figure 1) are arranged respectively, wherein two is circular hole, be used to install gear 2 and band arm gear 4, another hole is to be the arcuate socket in the center of circle with hole that gear 2 is installed, this arcuate socket is used to install gear 3, tooth bar 5 is installed in a side of shell 1, there is a hole its inside, be used to lay compression spring 7, respectively have one to protrude platform on its two sides, front and back, respectively there is a groove to match on the shell two sides with on the corresponding position of platform with the protrusion platform, but adopting this structure one is stationary rack 5, avoid it to move forward and backward, another is to increase tooth bar 5 and the accuracy of mesh of gear 2 and the distance that moves up and down of restriction tooth bar 5, tooth bar 5 installs its head of back and stretches out shell by the hole on shell 1 end face, this hole both can be used for installing tooth bar 5, tooth bar 5 is moved up and down, during real work, tooth on the tooth bar 5 and gear 2 engagements, thereby kinetic energy is passed to gear 2, gear 3 can move up and down in arcuate socket, rotation direction difference according to gear 2, gear 3 is engageable with band arm gear 4 or separate, band arm gear 4 is installed in another circular hole, its arm stretches out shell by the groove on the shell 1, on stretching out the arm of shell 1, it have several apertures to be used for installing and regulating rope, the position of extension spring 6, from Fig. 2, Fig. 3, Fig. 4 can find out, one end of extension spring 6 is connected on this arm, the other end is connected the one hook place, top of groove on the shell 1, its effect is after band arm gear 4 rotates the pulling rope, make band arm gear 4 return original readiness, its pulling force is less than the reaction force of compression spring 7, an end of rope is connected aperture place on the arm among the figure, the other end links to each other with manual jettison gear or piston by pulley, when band arm gear 4 rotates, it can spur jettison gear or piston, the lavatory is washed automatically, the first half of compression spring 7 is placed in the hole of tooth bar 5 among the figure, the other end is placed on the roundlet arc platform of shell, when tooth bar 5 is subjected to sit pressure under the human body, spring 7 compressions, when human body stands, tooth bar 5 is not subjected to downward power, the reaction force of spring 7 forces on the tooth bar 5 and moves, driven gear 2 work, the reaction force of compression spring 7 is greater than extension spring 6 and open the pulling force sum of the piston that discharges water.

The utility model is installed in the below (as shown in Figure 5) of flush toilet ceramics seat portion, need the flush toilet side bottom that one hole (can reserve when producing flush toilet) is arranged before installing, be used to install the utility model, be that the utility model upper left side need have an aperture below toilet seat, being used for tooth bar 5 stretches out, the head of tooth bar 5 surpasses the height of pottery, and below seat cushion, face (inner face) adhesion mutually be cannot see with the flush toilet below in the top of shell 1.The dead ahead of band arm gear 4 of the present utility model is equipped with a fixed block, and rope is linked in the catch basin manually on jettison gear or the piston by fixed block.

The course of work of the present utility model is as follows:

(1) when the utility model when not working, as shown in Figure 2.

(2) when human body is sat down, tooth bar 5 is subjected to a downward pressure F _Down(make the compression of compression spring 7,7 this moments of spring react on pressure F less than human body _On＜F _Down), and driven gear 2 is to counterclockwise rotating, and driven gear 3 rotates and moves up to clockwise direction, and gear 3 is separated with band arm gear 4, and band arm gear 4 is not worked, as shown in Figure 3.

(3) rise immediately when human body, tooth bar 5 is subjected to downward human pressure and disappears, and downward pressure is zero (F _Down=0), the reaction force maximum of compression spring 7, F _On＞F _DownDrive on the tooth bar 5 this moment moves, and driven gear 2 rotates to clockwise direction, driven gear 3 is to counterclockwise rotating and meshing with band arm gear 4, band arm gear 4 is rotated to clockwise direction, (rope connects on the former cock of water drain pulling rope, compresses the pulling force of the power of spring 7 greater than extension spring 6, F this moment _On＞F _Draw), reach the function that discharges water, as shown in Figure 4.

(4) (F after tooth bar 5 arrives peak _On=F _Down) separate (this position tooth bar 5 is anodontia) with gear 2, this moment extension spring 6 pulling force maximum (F _Draw＞F _On+ F _Down=0), and pulling band arm gear 4 is to counterclockwise rotating, driven gear 3 rotates to clockwise direction, driven gear 2 is to counterclockwise rotating, do not drive tooth bar 5 (because the tooth bar 5 of this moment does not mesh with gear 2), each part is got back to the preparation work state, for following task is got ready, as shown in Figure 2.

The utility model compared with prior art has following advantage: 1. can make water closet just Rear auto-flushing is convenient to old, weak, sick, residual, children's use; 2. can overcome uncivil phenomenon and behavior (mainly finger does not wash); 3. can make the water closet flushing in time, and using water wisely.
