Description

Technical Field

[0001] The invention relates to a faucet, in particular to a faucet with two functions of time delay and normal opening. Background Art

[0002] There are many styles of faucets on the market. The most common ones are traditional faucets with switch and size adjustment functions. Their functions are controlled by piston valves. The handle position is manually adjusted to control the water flow and switch status. At the same time, in order to save water and avoid cross infection, it effectively meets the special needs of public places such as hospitals and schools. However, since the pressure-type delay faucet has a short water flow time and a fixed water volume, it cannot achieve the function of continuous water flow and water volume control when a long water flow is required. Summary of the invention

[0003] The purpose of the present invention is to solve the functional imperfections of the above-mentioned two faucets and to provide a multifunctional delayed faucet, which has the functions of press-delayed water outlet and ordinary rotary water outlet. When the faucet handle is turned counterclockwise, it has the functions of an ordinary faucet, and can control the water flow rate and realize switching on and off at any time; when the upper control handle is pressed, it has the functions of a press-type delayed faucet, realizing the functions of pressing water outlet and delaying the closing of the water flow.

[0004] In order to solve the above technical problems: a multifunctional delayed faucet includes a shell, a valve core and a transmission shaft. A square opening is arranged on the top of the shell, and a water-stop rubber ring is arranged at the opening. A valve core is assembled inside the shell, and a water outlet opening is arranged at the lower part of the shell and is connected to the water outlet pipe. The bottom of the shell is fixedly connected to the base. The valve core is provided with a vertically arranged delayed water outlet hole and a horizontally arranged ordinary water outlet hole. A cavity is formed between the water-stop rubber ring and the shell above the valve core. A reset spring, a water-stop rubber ring and a damper are arranged on the upper end of the valve core. The reset spring is fixedly connected to the lower surface of the upper end of the shell and the upper surface of the valve core by the damper. The shell and the upper surface of the valve core The end plate, the water-stop rubber ring and the water inlet pipe form a water storage chamber. The transmission shaft is a square cross-section column on the upper surface of the shell and a circular cross-section column on the lower surface of the shell. The side length of the square cross-section column of the transmission shaft and the diameter of the circular cross-section column are slightly smaller than the square side length opening of the shell. The top end of the transmission shaft is fixedly connected to the pressing handle, the middle end of the transmission shaft is fixedly connected to the rotating handle, the transmission shaft passes through the upper opening of the shell and is fixedly connected to the top of the valve core. The limiter is located on the transmission shaft and the three protrusions on the bottom surface of the upper end plate of the shell. A protrusion along the normal of the transmission shaft is arranged at the lower part of the transmission shaft, and two protrusions with an angle difference of 90 degrees are arranged on the bottom surface of the upper end plate of the shell.

[0005] The delayed water hole and the ordinary water hole of the valve core are both arc-shaped holes. The delayed water hole is arranged on the valve core in the axial direction, and the delayed water hole of the valve core is located above the water outlet hole axis. The ordinary water hole is arranged on the valve core in the axial direction, and the ordinary water hole of the valve core is located on the right side of the water outlet hole axis. The delayed water outlet hole is on the vertical axis of the valve core, the normal water outlet hole is on the horizontal axis of the valve core, and the water outlet pipe and the water outlet hole of the shell intersect at one point along the axial line. There is a slight gap between the shell and the valve core, and a water-stop rubber ring is arranged on the top of the valve core.

[0006] The protrusion at the bottom of the transmission shaft and the protrusion on the bottom of the upper end plate of the shell form a limiter for limiting the rotation angle of the transmission shaft. When it rotates 90 degrees counterclockwise, the protrusion at the bottom of the transmission shaft rotates to the protrusion on the bottom of the upper end plate of the shell, thereby limiting the maximum counterclockwise rotation angle of the transmission shaft to 90 degrees. When the transmission shaft is reset and rotated clockwise, when it rotates to the initial position, the protrusion at the bottom of the transmission shaft contacts another protrusion on the bottom of the upper end plate of the shell, thereby limiting the maximum clockwise rotation angle of the transmission shaft to the initial test position.

[0007] When the faucet is in the initial state, the cross-section shape of the transmission shaft on the upper surface of the shell is circular, and the cross-section shape of the transmission shaft below the upper surface of the shell is square. After pressing the button, the transmission shaft moves downward, and the square transmission shaft can only move axially through the square hole, that is, it can only be pressed but not rotated. When the handle is rotated, the square on the upper end of the transmission shaft no longer coincides with the square hole, and the transmission shaft cannot move downward but can only rotate, thereby ensuring that the two functions are independent of each other. In the initial state, you can press to use the delayed water outlet function, or rotate the handle to use the normal water outlet function.

[0008] By adopting the above technical scheme, the working principle of the present invention is: when the handle is rotated counterclockwise, the drive shaft is driven to rotate counterclockwise through the rotation of the handle. At this time, the cross-sectional shape of the drive shaft inside the hole of the upper end plate of the shell is circular, and it can rotate in the hole of the upper end plate of the shell with a square cross-sectional shape. The drive shaft can smoothly complete the rotation, thereby driving the valve core connected to the bottom of the drive shaft to rotate counterclockwise, and the horizontally arranged ordinary water outlet hole rotates to coincide with the water outlet hole of the shell at a certain angle. Water flows from the inner cavity through the ordinary water outlet hole of the valve core and coincides with the water outlet hole of the shell to form a water outlet hole, and flows through the water outlet pipe to the outside. The rotation angle of the handle determines the size of the hole formed by the coincidence of the ordinary water outlet hole of the valve core and the water outlet hole of the shell, that is, the rotation angle of the handle controls the size of the water outlet flow rate.

[0009] When the handle is turned clockwise to return to its original position, the transmission shaft is driven to rotate clockwise by the rotation of the handle, and then the valve core connected to the bottom of the transmission shaft is driven to rotate clockwise, the horizontally arranged ordinary water outlet hole and the shell water outlet hole overlap with the angle of the hole formed by the inner cavity through the normal water outlet hole of the valve core and the shell water outlet hole overlap, and the hole formed by the overlap of the normal water outlet hole of the valve core and the shell water outlet hole is reduced, and then the water outlet is reduced. When the ordinary water outlet hole and the shell water outlet hole are completely misaligned, the water outlet is closed.

[0010] When the button is pressed, the cross-sectional dimension of the transmission shaft on the upper surface of the shell is circular, and the transmission shaft can pass through the circular hole in the upper end plate of the shell to realize the vertical movement of the transmission shaft, thereby pushing the valve core and driving the reset spring at the same time. The valve core moves downward under the thrust, and the delay hole on the valve core coincides with the water outlet hole of the shell. Water flows from the inner cavity through the delayed water outlet hole of the valve core and coincides with the water outlet hole of the shell to form a water outlet hole, and flows through the water outlet pipe to the outside. After the pressing action is completed, the water-stop rubber ring and the damper jointly generate damping for the spring reset, and the reset spring is reset due to the damping delay, and the reset spring drives the valve core connected at the lower part to move upward. When the reset spring is reset, the water outlet hole of the shell and the delayed water outlet hole of the valve core are misaligned, and the water outlet of the faucet is closed.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1-2 The present invention is a multifunctional time-delay faucet, comprising a time-delay button 1, a common water outlet handle 2, a transmission shaft 3 fixedly connected with the time-delay button and the common water outlet handle, a circular cross-section column 3.2 at the lower part of the transmission shaft 3 passes through an opening 5.1 on the upper end plate of a shell and is fixedly connected with a piston 10, a water-stop rubber ring 4 is arranged at the opening 5.1 on the upper end plate of the shell to facilitate axial movement and rotation of the transmission shaft 3, a damper 6, 8 with a damping function respectively fixes the two ends of the reset spring to the upper end plate 5 of the shell and the valve core 10, the upper end plate 5 of the shell has two protrusions 5.2 which together with the protrusion 3.3 in the middle of the transmission shaft 3 constitute a limiter for limiting the rotation angle of the transmission shaft, the valve core 10 is provided with a time-delay function water outlet hole 10.1 and a common water outlet hole 10.2, the water outlet hole 11.1 of the shell is fixedly connected with the water outlet pipe 12, and the water pipe inlet base 13 is fixedly connected with the shell 11. Example

[0015] When the handle 2 is turned counterclockwise, the transmission shaft 3 is driven to rotate counterclockwise through the rotation of the handle 2. When the transmission shaft is not pressed, the transmission shaft 3 has a circular cross-sectional shape inside the opening 5.1 of the upper end plate of the shell, and can rotate in the upper end opening 5.1 of the shell with a square cross-sectional shape, thereby driving the valve core 10 connected to the bottom of the transmission shaft to rotate counterclockwise, and the horizontally arranged ordinary water outlet hole 10.2 rotates to coincide with the water outlet hole 11.1 of the shell at a certain angle. Water flows from the inner cavity through the ordinary water outlet hole 10.2 of the valve core and coincides with the water outlet hole 11.1 of the shell to form a water outlet hole, and flows through the water outlet pipe 12 to the outside. The rotation angle of the handle determines the size of the hole formed by the coincidence of the normal water outlet hole of the valve core and the water outlet hole of the shell, that is, the rotation angle of the handle controls the size of the water outlet flow rate. When it is rotated 90 degrees counterclockwise, the protrusion 3.3 in the middle of the transmission shaft 3 contacts the upper end protrusion 5.2 of the upper end plate of the shell to block the transmission shaft from continuing to rotate counterclockwise, that is, the maximum counterclockwise rotation angle is guaranteed to be 90 degrees.

[0016] When the handle 2 is turned clockwise, the transmission shaft 3 is driven to rotate clockwise through the rotation of the handle 2. When the transmission shaft is not pressed, the internal cross-sectional shape of the transmission shaft 3 in the opening 5.1 of the upper end plate of the shell is circular, and it can rotate in the upper end opening 5.1 of the shell with a square cross-sectional shape, thereby driving the valve core 10 connected to the bottom of the transmission shaft to rotate clockwise. The overlapping angle of the horizontally arranged ordinary water outlet hole 10.2 and the shell water outlet hole 11.1 decreases as the valve is rotated clockwise. The rotation angle of the handle determines the size of the hole formed by the overlap of the normal water outlet hole of the valve core and the water outlet hole of the shell, that is, the rotation angle of the handle controls the water outlet flow rate. When rotated 90 degrees clockwise, the protrusion 3.3 in the middle of the transmission shaft 3 contacts the upper end protrusion 5.2 on the upper end plate of the shell to block the transmission shaft from continuing to rotate clockwise, that is, the maximum clockwise rotation angle is guaranteed to the initial position.

[0017] When the button 1 is pressed, the cross-sectional shape of the transmission shaft 3 on the upper surface of the shell is circular, and the cross-sectional shape of the inner part of the shell is square, which can pass through the circular hole 5.1 at the upper end of the shell to realize the vertical movement of the transmission shaft, thereby pushing the valve core 10 and driving the reset spring 7 at the same time. The valve core 10 moves downward under the thrust, and the delay hole 10.1 on the valve core 10 coincides with the water outlet hole 11.1 of the shell 11. The water flows from the inner cavity through the valve core delay water outlet hole 10.1 and coincides with the water outlet hole 11.1 of the shell to form a water outlet hole. The water flows through the outlet pipe 12 to the outside. After the pressing action is completed, the water-stop rubber ring 9 and the dampers 6 and 8 jointly generate damping for the spring reset. The reset spring 7 is delayed by the damping and resets. The reset spring 7 drives the valve core 10 connected at the lower part to move upward. When the reset spring 7 is reset, the shell water outlet hole 12.1 and the valve core delayed water outlet hole 11.1 are misaligned. When the reset spring 7 is completely reset, the delayed water outlet hole 10.1 and the shell water outlet hole 11.1 are completely misaligned, and the formed water outlet channel is closed, and the faucet water outlet is closed.
