Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present invention, but is not intended to limit the present invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1-6, the embodiment provides a faucet capable of controlling water outlet time mechanically, which comprises a housing 1 and a handle 4, wherein the housing 1 is divided into a vertical water inlet housing 1a and a horizontal water outlet housing 1b, which are communicated with each other, a water outlet 1c is arranged at the other end of the water outlet housing 1a, a vertical valve rod 2 is arranged in the water inlet housing 1a, a valve cover 3 is arranged at the top of the water outlet housing 1a, the top of the valve rod 2 penetrates through the housing 1 and extends into the valve cover 3, the handle 4 penetrates through the side wall of the valve cover 3 and is fixedly connected with the top of the valve rod 2, a movable water baffle 6 vertical to the handle 2 is fixedly inserted in the middle of the valve rod 2, and when the handle 4 rotates, the handle 4 drives the valve rod 2 and the movable water baffle 6 to rotate around a shaft.
The utility model discloses a valve rod 2, including the casing 1a, be equipped with horizontal fixed breakwater 7 on the casing 1a inner wall of intaking, fixed breakwater 7 is located activity breakwater 6 top, two breakwater all are semi-circular, and be provided with the guiding hole on the fixed breakwater 7 and supply valve rod 2 passes. When the faucet is not in operation, the handle 4 is positioned at an original position, the fixed water baffle 7 and the movable water baffle 6 are staggered and laminated to form a complete circle when seen from a vertical projection direction, and the movable water baffle 6 is pushed upwards by water pressure and is clung to the bottom wall of the fixed water baffle 7, so that fluid is blocked from passing through; when the faucet works, the handle 4 is forced to rotate, and the movable water baffle 6 is driven to deflect by the valve rod 2, so that a gap is formed between the movable water baffle and the fixed water baffle 7, and fluid can pass through the gap.
A fixed rod 10 parallel to the valve rod 2 is arranged in the water inlet shell 1a, specifically, the bottom of the fixed rod 10 is fixed on the fixed water baffle 7, the top of the fixed rod is equal to the valve rod 2 in height, a torsion spring 5 is sleeved on the valve rod 2, one end of the torsion spring 5 is fixedly connected with the valve rod 2, and the other end of the torsion spring 5 is fixedly connected with the fixed rod 10; thereby, the torsion spring 5 provides an automatic reset function for the valve rod 2. Specifically, when the faucet is not in operation, the torsion spring 5 is in a normal state, and no resilience force is generated; when the handle 4 rotates, the compression deformation of the torsion spring 5 is driven, the torsion spring slowly returns to the original state under the rebound action, and the handle 4 is driven to return to the original position, so that the faucet is closed. The telescopic distance of the torsion spring 5 can also be different in time for the faucet handle 4 to restore to the original position, so that the water outlet time of the faucet can be different, the method can be utilized to realize automatic water closing of the faucet, the water outlet time can be controlled, and the design is more in line with the actual water habit of people.
According to the action characteristics of the torsion spring 5, the rotation amplitude of the handle 4 is proportional to the reset time of the torsion spring 5, a user can obtain the desired water outlet time by controlling the rotation angle of the handle 4, after the handle 4 is loosened, the handle 4 and the movable water baffle 6 can realize reverse rotation under the rebound action of the torsion spring 5, the gradual valve closing is automatically realized, the water outlet time in the whole process is flexible and controllable, and no water source is consumed.
Of course, in other embodiments, the fixed rod 10 is not used as a necessary element, the driven end of the torsion spring 5 is fixedly connected with the inner wall of the water inlet housing 1a or the inner wall of the valve cover 3 instead, even as shown in fig. 7 and 8, the driving end of the torsion spring 5 is connected with the tail end of the handle 4, and the driven end is connected with the inner wall of the valve cover 3, so that the automatic reset of the valve rod 2 can be realized, therefore, the installation position of the torsion spring 5 is not limited specifically, and any connection relationship that adopts the torsion spring to enable the valve rod to rotate is within the scope of the technical scheme.
It is further added that any form of torsion spring can be used for the present invention as long as the spring force can be provided, and thus the present invention is not particularly limited to the form of the torsion spring 5.
It should be appreciated that the valve cover 3 is provided with corresponding clearance grooves within the rotation range of the handle 4, so as to ensure the normal operation of the handle 4. On this basis, the outer edge of the bottom of the valve cover 3 is marked with a time scale around the shaft, the time is the time required for the handle 4 to restore to the original position at the position, and the time of water outlet of the water tap is represented, for example, the time scales of water outlet are 5s, 15s and 30s respectively. Therefore, the actual water outlet time is determined by the design parameters of the torsion spring 5, the time spent by rebound recovery of the torsion spring 5 at different positions is the water outlet time at the corresponding position, and the marks of the time scales greatly promote the understanding of a user on the faucet use, so that the device is more concise and understandable.
The valve cover 3 is provided with a concave clamping groove 9 below each time scale, the clamping groove 9 is adapted to the shape and the size of the bottom of the handle 4, preferably, the handle 4 is provided with a vertical flat shape, and the clamping groove 9 is provided with a corresponding grooving form; because of the up-down lamination design of the fixed water baffle 7 and the movable water baffle 6, the handle 4 can move up and down to a limited extent, the handle 4 can be pressed down into the clamping groove 9 to be clamped, at the moment, the valve rod 2 and the movable water baffle 6 are positioned along with the clamping groove, and the water tap can continuously supply water in an equivalent amount; when water is not needed to be discharged, the user lifts the handle 4 upwards, the handle 4 automatically rotates back to the original position, in the process, the water flow is gradually reduced, and the user can utilize the water flow to continue washing hands, so that the condition that the hands are not clean after the user contacts the handle 4 for the second time is avoided.
It is added that the axis of the valve rod 2 and the axis of the valve cover 3 are positioned in the same straight line, and the clamping groove 9 is arranged around the axis, so that the time scale and the orientation of the clamping groove 9 are matched with the position of the handle 4, and the arrangement is convenient for a user to quickly identify and operate.
In this embodiment, a waterproof rubber ring 8 is disposed at the connection between the valve rod 2 and the top wall of the housing 1, so as to prevent fluid leakage when the handle 4 is pulled up and down.
The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
