Description

Technical Field

[0001] The invention relates to an electronic timer, in particular to an electronic timer with the function of eliminating the water hammer effect of an electromagnetic valve. Background Art

[0002] The electronic timer is an automatic control device widely used in garden sprinkler irrigation environments. It can mainly start the water channel for sprinkler irrigation at a fixed time according to the pre-set conditions of the user manager and automatically shut down the water channel at the set time, thereby helping relevant users to achieve the state of automatic control.

[0003] However, in actual use, prior art electronic timers have been found to have the following problems. For example, because electronic timers utilize the action of a solenoid valve to open and close the waterway, and the solenoid valve operates very quickly, switching from open to closed in an instant, this process is prone to water hammer due to the sudden interruption of the high flow rate in the waterway. Excessive water hammer can easily cause joints and weak points in the waterway to rupture and damage due to the high impact, thereby increasing the failure rate and maintenance costs of waterway-related equipment.

[0004] Although some relevant industries have introduced a water hammer damper that can be installed separately at the front of the faucet, for most gardening water pipe configurations, due to the large number of water outlets, it is time-consuming, labor-intensive and expensive to install a water hammer damper one by one. Therefore, it is still not ideal and needs further improvement. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the object of the present invention is to provide an electronic timer with the function of eliminating the water hammer effect of the solenoid valve.

[0006] The technical solution of the present invention is: an electronic timer with the function of eliminating the water hammer effect of the solenoid valve, the electronic timer comprises:

[0007] A housing body, which is a hollow shell and includes an internal accommodating space;

[0008] A water pipe is provided through the housing body, with an inlet portion and an outlet portion provided at both ends of the water pipe for introducing and outlet water flow, respectively. The inlet portion and the outlet portion are connected by a water control section, and the water control section corresponds to the internal accommodation space of the housing body;

[0009] an electromagnetic control valve, provided in the water control section of the water pipe, for switching the water flow of the water pipe on or off;

[0010] A control interface is provided on the housing, the control interface including a plurality of control keys for setting the automatic operation time state of opening or closing the water flow of the water pipe;

[0011] A water hammer buffer is provided between the electromagnetic control valve of the water pipe and the inlet portion. The water hammer buffer includes a water inlet and a buffer component. The water inlet is connected to the water control section to introduce water flow, and the buffer component is used to produce an elastic buffering effect on the water flow, thereby alleviating the water hammer effect generated by the water flow.

[0012] Furthermore, the buffer component of the water hammer buffer includes a pipe seat, a piston, a spring and a cap, wherein the pipe seat is aligned and connected to the outside of the water outlet, a sliding cavity and an installation port are formed in the pipe seat, the piston is slidably arranged in the sliding cavity, the cap is sealed in the installation port, and the spring is assembled between the piston and the cap to elastically support the piston toward the water outlet.

[0013] Furthermore, one end of the piston extends to form a guide rod, so that the cap forms a through hole for the guide rod to pass through.

[0014] Furthermore, the through-hole of the cap is formed with an internal thread section, and an adjusting bolt is provided, including a pressing end, a passive rotating end and an internal avoidance cavity. The pressing end is used to press against the spring, and the outer periphery of the adjusting bolt is provided with an external thread section to be screwed together with the internal thread section, so that the adjusting bolt can be rotated forward and reversely to perform a lifting and lowering movement relative to the cap, thereby adjusting the height of the pressing end to change the supporting elastic force of the spring. The passive rotating end extends to a predetermined position of the shell base, and the shell base is correspondingly provided with an opening to expose the passive rotating end. The passive rotating end is formed with a tool socket for use with existing tools, and the internal avoidance cavity is used for a guide rod formed at one end of the piston member to extend into it and be in a lifting and lowering actuation state.

[0015] The beneficial effect of the present invention is that the present invention can produce an elastic buffering effect on the water flow, thereby alleviating the water hammer effect produced by the water flow, thereby achieving the effect of extending the service life of the electronic timer.

DETAILED DESCRIPTION

[0025] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting description of the features of the present invention is now provided below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 5 As shown, an electronic timer with the function of eliminating the water hammer effect of a solenoid valve, the electronic timer comprises:

[0027] A housing 10 is a hollow shell and includes an internal accommodating space 11;

[0028] A water pipe 20 is provided through the housing 10. The water pipe 20 has an inlet portion 21 and an outlet portion 22 at each end for introducing and discharging water. The inlet portion 21 and the outlet portion 22 are connected by a water control section 23. The water control section 23 corresponds to the internal accommodating space 11 of the housing 10.

[0029] an electromagnetic control valve 30 , provided at the water control section 23 of the water pipe 20 , for switching the water flow of the water pipe 20 on or off;

[0030] A control interface 40 is provided on the top surface of the housing 10. The control interface 40 includes a plurality of control keys 41 for setting the automatic operation time state of opening or closing the water flow of the water pipe 20;

[0031] A water hammer buffer 50 is provided between the electromagnetic control valve 30 of the water pipe 20 and the inlet portion 21. The water hammer buffer 50 includes a water inlet 51 and a buffer member 52. The water inlet 51 is connected to the water control section 23 to introduce water flow, and the buffer member 52 is used to produce an elastic buffering effect on the water flow, thereby alleviating the water hammer effect generated by the water flow.

[0032] like Figure 3-Figure 5 As shown, the buffer component 52 of the water hammer buffer 50 includes a pipe seat 521, a piston 522, a spring 523 and a cap 524, wherein the pipe seat 521 is aligned and connected to the outside of the water outlet 51, and a sliding cavity 525 and a mounting port 526 are formed in the pipe seat 521. The piston 522 is slidably disposed in the sliding cavity 525 (and is sealed by a water stop ring 54), and the cap 524 is sealed in the mounting port 526. The spring 523 is assembled between the piston 522 and the cap 524 to elastically support the piston 522 toward the water outlet 51.

[0033] like Figure 3 、 Figure 4 As shown, one end of the piston 522 extends to form a guide rod 527, so that the cap 524 forms a through hole 528 for the guide rod 527 to pass through. The advantage of the guide rod 527 is that it makes the piston 522 more stable and less likely to deviate during movement.

[0034] like Figure 6 As shown, the through hole 528 of the cap 524 is formed with an internal thread section 529, and an adjusting bolt 53 is provided, which includes a pressing end 531, a passive turning end 532, and an internal avoidance cavity 533. The pressing end 531 is used to press against the spring 523. The outer periphery of the adjusting bolt 53 has an external thread section 534 to be screwed with the internal thread section 529, so that the adjusting bolt 53 can rotate in the forward and reverse directions to move up and down relative to the cap 524, thereby adjusting the height of the pressing end 531 to change the supporting elastic force of the spring 523 (see FIG. Figure 7 and Figure 8The driven rotating end 532 extends to a predetermined position of the shell base 10, and the shell base 10 is correspondingly provided with an opening 12 to expose the driven rotating end 532 (not limited to a convex or concave state). The driven rotating end 532 is formed with a tool socket portion 535 (such as a flat-blade hole, a cross hole, or a hexagonal hole) for use with existing tools (such as a flat-blade screwdriver, a cross screwdriver, a hexagonal wrench, etc., not shown in the figure). The internal avoidance cavity 533 is used for a guide rod 527 formed at one end of the piston member 522 to extend thereinto and be in a lifting and lowering actuation state.

[0035] When the present invention is actually used, Figure 4 As shown in FIG, when the electromagnetic control valve 30 is in the open state, the water flow in the water pipe 20 is relatively smooth. On the contrary, when the electromagnetic control valve 30 is in the closed state, as shown in FIG. Figure 5 As shown, the water flow in the water pipe 20 will be blocked instantly, and the water flow will turn to impact the water outlet 51 of the water hammer buffer 50. At this time, the buffer component 52 will produce an elastic buffering effect on the water flow, thereby alleviating the water hammer effect generated by the water flow, thereby achieving the effect of extending the service life of the electronic timer.

[0036] Of course, the above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All simple modifications and equivalent structural changes made using the contents of the description and drawings of the present invention should be included in the patent protection scope of the present invention.
