Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.
The terms "first," "second," and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.
Referring to fig. 1 to 4, a water outlet device 100 includes two water inlet pipes 1, the water inlet pipes 1 are respectively connected to a cold and hot water source, the water outlet device 100 further includes a control assembly 2 communicated with the two water inlet pipes 1, the control assembly 2 mixes a ratio of cold and hot water, the water outlet device 100 further includes a water outlet pipe 3 communicated with the control assembly 2, and water enters the control assembly 2 from the water inlet pipe 1 and then flows out to the water outlet pipe 3 from the control assembly 2.
Waterproof hammer subassembly 4 still includes the slip subassembly, the slip subassembly is including sliding in the pressure release channel sliding block 421 with push up to be in the casing with elastic component 422 between the sliding block 421, the slip subassembly still includes along the circumference of sliding block 421 sets up and pushes up to the sealing member 423 of pressure release channel's inner wall, in this embodiment, pressure release channel with sliding block 421 is circular shape cross section, sealing member 423 is O type sealing washer, when sliding block 421 receives the water pressure effect to slide along the direction of keeping away from water channel 411, elastic component 422 accumulates elasticity, the elastomer is the spring, pressure release channel is in sliding block 421 receives the opposite side of water pressure still is provided with through-hole 4123 with external intercommunication.
The pressure relief channel comprises a first pressure relief channel 4121 and a second pressure relief channel 4122 extending from the first pressure relief channel 4121 to be far away from the water passing channel 411, the inner diameter of the second pressure relief channel 4122 is smaller than that of the first pressure relief channel 4121, the first pressure relief channel 4121 is communicated with the water passing channel 411, the pressure relief channel extends at a certain angle with the water passing channel 411, the axis of the pressure relief channel intersects with that of the water passing channel 411, and a first limiting step 413 which is radially retracted is further arranged at the connection position of the first pressure relief channel 4121 and the water passing channel 411, and because the inner diameter of the second pressure relief channel 4122 is smaller than that of the first pressure relief channel 4121, the high-low pressure relief difference between the first pressure relief channel 4121 and the second pressure relief channel 4122 can be used as a second limiting step 414.
When the sliding block 421 is not under the action of water pressure, the sliding block 421 is pressed against the first limit step 413 by the elastic member 422. When the sliding block 421 is under the action of water pressure, the sliding block 421 slides in the direction away from the water passage 411 and abuts against the second limit step 414 at most, and the sliding block 421 slides between the first limit step 413 and the second limit step 414. The first limit step 413 and the second limit step 414 can limit the sliding range of the sliding block 421, and can prevent the elastic element 422 from being overloaded, resulting in the occurrence of the situations such as the elastic element 422 being stuck, and thus, the service life of the elastic element 422 can be effectively prolonged.
The housing includes a main body 415 defining the water passing passage 411 and the first pressure relief passage 4121, and the housing further includes a cover 416 defining the second pressure relief passage 4122, wherein the main body 415 and the cover 416 are detachably connected.
The main body 415 is provided with a first fastening member 4151 at the outlet of the first pressure relief channel 4121 along the circumferential direction, and the cover 416 is provided with a first fastening fitting 4161 fitted with the first fastening member 4151. The cover 416 further has a through hole 4123 communicating the second pressure relief passage 4122 with the outside, the first fastening member 4151 is of an external thread structure, and the first fastening fitting member 4161 is of an internal thread structure.
When the sliding block 421 slides in a direction away from the water passage 411 under the action of water pressure, the through hole 4123 can extrude air in the pressure relief space out of the through hole 4123, so as to prevent the air compression in the pressure relief space from generating a reaction force on the sliding block 421, thereby reducing the effect of a water hammer.
The main body 415 is further provided with a second fastening member 4152 along the water outlet 4112 of the first water passage 411, and the water inlet pipe 1 is provided with a second fastening fitting (not shown), in this embodiment, the water inlet pipe 1 is a hose. When the control component 2 controls to make the water outlet device 100 in a water outlet state, water enters the water passage 411 from the water inlet 4111 of the water passage 411 through the check valve component 4113, and at this time, the sliding block 421 abuts against the first limit step 413 under the action of the elastic member 422. Water enters the water inlet pipe 1 from the water outlet 4112 of the water passage 411, then enters the control assembly 2, and then enters the water outlet pipe 3. When the control component 2 controls the water outlet device 100 to be closed in the water outlet state, because water flows in the water passage 411 and the water inlet pipe 1 with inertia, the water flow is stopped suddenly under the condition that the downward flow of the water inlet pipe 1 is cut off, and the water pressure can be increased temporarily due to the inertia, at this time, if the water hammer preventing component 4 is not arranged, the water pressure is increased suddenly, so that the water passage 411 and the water inlet pipe 1 shake greatly, particularly, the water inlet pipe 1 is a hose, the shaking is more severe, and thus, the water inlet pipe 1 can be damaged more.
Have under the condition of waterproof hammer subassembly 4, hydraulic sudden increase can make the entering water channel 411's water pressure also increases, because at this moment sliding block 421 can be along keeping away from water channel 411's direction slides, sliding block 421 is pushed away this moment, and water can get into in the pressure release channel, the inertial action of this kind of water just is reduced, and the shake of inlet tube 1 also slows down, and the noise reduces. When the sliding block 421 slides in a direction away from the water passage 411, the air in the second pressure relief passage is discharged from the through hole 4123, so that the air in the second pressure relief passage does not affect the sliding of the sliding block 421.
The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
