Description

toilet free flusher

technical field

The utility model relates to an automatic flusher for toilet flushing, in particular to a pedal type automatic flusher.

Background technique

At present, the flushers on the domestic and foreign markets are mainly divided into two categories: one is mechanical, and the other is induction. Mechanical categories include tank-type manual pull cord flushers and button-type hand (foot) controlled flushers. Sensing categories include voice-activated and light-activated flushers.

The water tank-type manual pull cord flusher generally stores water first and then flushes, and the flushing is realized by pulling the pull cord that controls the opening of the flusher; the hand (foot) push type flusher requires the hand pressure of the toilet user. Or pedal to realize flushing. These two kinds of water flushers all need people's subjective operation to realize the water flushing function. However, many people often do not have the consciousness of actively flushing after defecating, which naturally brings inconvenience to the follow-up and has a certain impact on the environment.

Inductive flushers can perform automatic flushing without human subjective operation, and are easy to use, but they are mainly used in urinals, and have not been well promoted in squatting urinals. And its high cost, inconvenient maintenance and detection, and the use of electric energy, this invisibly limits the range of use of induction flushers.

Patent CN200620065517.X proposes a foot-operated flusher. When a person steps on the foot-operated device, the switch of the water tank is controlled by the connecting wire rod to automatically fill the water tank; when the person leaves the pedal device, the water tank is controlled by the connecting wire rod. The water tank is switched on and off, and the water will flow out automatically to complete the toilet flushing. The flusher realizes flushing through the water tank. The water tank is generally large in size and requires a certain upper space, and the water tank is placed at a high place, which brings inconvenience to maintenance; Added noise in public places.

Utility model content

The technical problem to be solved by the utility model is to provide a flusher which does not need a water tank and has an automatic flushing function.

In order to solve the above-mentioned technical problems, the utility model proposes the following flusher, which is mainly composed of a water valve, a left and right pedal device and a steel wire rope, and flushing is realized through the water valve. The water valve is composed of a valve body, a valve stem, a valve cover and a valve seat. The valve cover is directly connected with the water pipe, and the lower end of the valve stem is connected with the pedal device through a steel wire rope. The valve body has an upper sealing water port and a lower sealing water port; the valve stem is equipped with upper and lower rubber pads for sealing the upper and lower sealing water ports; an overflow groove for slow return is opened on the valve seat. The left and right pedal devices include a box-shaped pedal and a cross mechanism.

When a person steps on the pedal device, the valve stem moves down, and the upper rubber pad seals the upper sealing water port. When the person leaves the pedal device after going to the toilet, the upper sealing water port opens to realize the flushing function. The overflow tank is used to control the flushing time.

The utility model adopts the principle of overflow, and utilizes the necessary process of people stepping on and leaving the pedal device when going to the toilet, which solves the problem that many people often do not flush after using the urinal, which brings inconvenience to subsequent users Problems, and simple structure, energy saving and environmental protection, easy installation and maintenance.

Detailed ways

When a person steps on the pedal device 5, the valve rod 16 in the water valve 1 is driven to move downward quickly through the steel wire rope 3. At this time, the lip-shaped sealing ring 17 deforms and shrinks, and the water in the valve seat cavity 20 is quickly squeezed out. The upper rubber pad 10 seals the upper sealing water port 12, and the lower rubber pad 14 leaves the lower sealing water port 13. During this process, a small amount of water flows into the urinal 4 to moisten the urinal 4, which can reduce the excrement and the urinal 4. Adhesion, which is beneficial to flushing; when leaving the pedal device after entering the toilet, under the spring force of the spring 22, the valve stem 16 moves upward, the upper sealing water port 12 is quickly opened, and the tap water flushes the urinal through the water outlet 15 until the lower The rubber pad 14 seals the lower sealing water port 13, and the flushing is completed.

When the valve stem 16 moves upwards, the lip seal 17 expands due to the hydraulic pressure, the valve seat chamber 20 forms a vacuum, and tap water is sucked in through the overflow groove 19 in the shape of a gap, thereby ensuring that the upper sealing water port 12 is quickly sealed. After opening, the valve stem 16 slowly moves upwards to the initial state, and in the slow return process, the purpose of sufficient flushing water is achieved.

The left and right pedal devices include a box-shaped pedal and a cross mechanism. Cross mechanism is made of upper plate 23, wire rope fixing nut 24, lower plate 25 and spring 26, and upper and lower plates are in a cross shape, wherein lower plate 25 is fixed, and cross mechanism is contained in the described box-shaped foot pedal. When the person steps on the box-shaped pedal, the upper plate 23 moves downward, driving the steel wire rope 3 to pull down, and the spring 26 is in a compressed state. When the person leaves the box-shaped pedal, the upper plate 23 returns to the initial state by the spring force, and then Box pedals are back.
