Description

Technical Field

[0001] The utility model relates to a water outlet structure, in particular to a water outlet structure with a teeth washer. Background Art

[0002] Tooth washer, also known as water flosser, dental scaler or water flosser, is commonly used to clean the oral cavity. The main principle is to use a soft pulse of water to flush the gaps between teeth to remove residues and clean the tongue. Existing tooth washer is generally a separate component, mainly including the tooth washer body and a water tank. Before use, the water tank needs to be filled with water before the tooth washing process can be carried out. Therefore,

[0003] In the prior art, there is a tooth washer that is directly connected to the water path of a water outlet device such as a faucet, a shower, etc. For example, Chinese patent CN208907490U discloses an oral hygiene device with a faucet function. Since the tooth washer in this scheme is directly connected to the water path, it is no longer necessary to configure a water tank. However, when using this tooth washer, the water outlet to the water outlet of the faucet and the water outlet to the main body core block of the oral hygiene device are controlled by controlling the different rotation directions of the valve core operating handle. That is, when using the tooth washer, it is also necessary to operate the handle on the faucet, which is still inconvenient when using it. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] like Figure 1 and Figure 2 As shown, the water outlet structure with a tooth washer of the utility model takes a water outlet faucet as an example, and the water outlet structure includes a tooth washer 1, a water outlet pipe 2, a water outlet body 3, a left switch 61, a right switch 62, a water inlet mechanism 6, a pressure reducing valve 7, a pull-out hose 81 and a heavy hammer assembly 82.

[0044] See also Figures 3 to 5 The water outlet body 3 includes a water outlet pipe valve core 4 and a fixing device 31 arranged side by side. The water outlet pipe valve core 4 can be installed in a valve core cavity 32 arranged on the front side of the fixing device 31 of the water outlet body 3. The water outlet pipe 2 is installed on the water outlet body 3 and connected to the water outlet pipe valve core 4. The water outlet pipe 2 can be a curved pipe, and the tooth washer 1 can be removably inserted into the fixing device 31.

[0045] The fixing device 31 of this embodiment is a hole opened in the water outlet body 3. Of course, the fixing device 31 can be any structure as long as it can place the tooth washer 1 without falling off.

[0046] A control piston 42 is provided in the water outlet valve core 4. When the tooth washer 1 is inserted into the fixing device 31, the control piston 42 is driven to move and open the water path S inside the water outlet valve core 4. After the tooth washer 1 is separated from the fixing device 31, the control piston 42 is reset to close the water path S inside the water outlet valve core 4.

[0047] At the same time, the tooth washer 1 is connected to the pull-out hose 81, and the pull-out hose 81 and the water outlet pipe valve core 4 are both connected to the water inlet mechanism 6, and water is supplied by the water inlet mechanism 6 at the same time, and the water inlet mechanism 6 controls the water outlet by the left switch 61 and / or the right switch 62.

[0048] Therefore, when the water inlet mechanism 6 supplies water, the water outlet pipe 2 supplies water synchronously, and the water path of the tooth washer 1 is connected at the same time. After the tooth washer 1 is picked up from the fixing device 31, the water outlet of the tooth washer 1 can be achieved by operating the control button 11 of the tooth washer 1 itself, without the need to additionally switch the left switch 61 and / or the right switch 62. After the tooth washer 1 is picked up, the control piston 42 is controlled to simultaneously close the water path of the water outlet pipe valve core 4, so that the water outlet pipe 2 automatically stops supplying water, and the water of the water inlet mechanism 6 is uniformly supplied to the tooth washer 1, ensuring that the water pressure of the tooth washer 1 is sufficient.

[0049] Moreover, after use, the water outlet of the tooth washer 1 is turned off and then put back into the fixing device 31. At this time, the control piston 42 is activated to open the water path of the water outlet pipe valve core 4, and the water outlet pipe 2 starts to discharge water again, thereby reminding the user to control the left switch 61 and / or the right switch 62 to turn off the water outlet of the water inlet mechanism 6, so as to avoid the tooth washer 1 being damaged due to long-term pressure buildup and inability to observe the water path status due to the fact that the tooth washer 1 does not discharge water.

[0050] See also Figure 8 The water inlet mechanism 6 may include a left switch 61, a right switch 62 and a four-way joint 63. The left switch 61 and the right switch 62 may be distributed on the left and right sides of the water outlet body 3. The input ends of the left switch 61 and the right switch 62 may be connected to the hot water pipe and the cold water pipe respectively, and the output ends of the left switch 61 and the right switch 62 may be connected to the left and right joints of the four-way joint 63 respectively, thereby directly realizing the mixed water outlet of hot and cold water inside the four-way joint 63.

[0051] The upper joint of the four-way joint 63 can be connected to the input end of the water outlet valve core 4 through the connecting pipe 5, and the output end of the water outlet valve core 4 is connected to the water outlet pipe 2. The lower joint of the four-way joint 63 can be connected to one end of the pull hose 81. Therefore, the water outlet pipe 2 and the tooth washer 1 are supplied with water by the water inlet mechanism 6 at the same time.

[0052] The left, right and upper joints of the four-way joint 63 can be respectively configured as quick-connect joints to facilitate quick connection with the output ends of the connecting pipe 5 , the left switch 61 and the right switch 62 .

[0053] The water inlet mechanism 6 of this embodiment is an example of a four-way joint 63, a left switch 61, and a right switch 62, which has a simple structure and low cost. Of course, the water inlet mechanism 6 can also be other water inlet structures such as a hot and cold water mixing valve, and the left switch 61 and the right switch 62 are integrated into the switch of the mixing valve, and the hot and cold water output of the water inlet mechanism 6 is directly controlled by the switch.

[0054] like Figure 1 and Figure 2 The other end of the pulling hose 81 can movably pass through the bottom of the water outlet body 3 and be fixedly connected to the input end of the tooth washer 1 in the fixing device 31 , and the heavy hammer assembly 82 is installed on the pulling hose 81 .

[0055] Therefore, when taking out the tooth washer 1 from the fixing device 31, the pull-out hose 81 can be pulled out at the same time, and water can be directly supplied by the pull-out hose 81 and the water inlet mechanism 6. A control button 11 is provided on the body of the tooth washer 1. The water can be discharged by directly pressing the control button 11 by holding the tooth washer 1. At the same time, the weight hammer assembly 82 can provide a gravity pulling force to restore the tooth washer 1 to its original position, thereby ensuring that the tooth washer 1 is accurately reset in the fixing device 31 and ensuring that the control piston 42 opens the water path of the water outlet pipe valve core 4.

[0056] like Figures 5 to 7 As shown, the water outlet pipe valve core 4 includes a valve core body 41 and the control piston 42. The valve core body 41 includes an upper joint chamber 411 and a lower joint chamber 412. The upper joint chamber 411 and the lower joint chamber 412 are respectively connected to the water outlet pipe 2 and the connecting pipe 5.

[0057] The piston chamber 413 is located between the upper joint chamber 411 and the lower joint chamber 412. The piston chamber 413 includes a left chamber 414 and a right chamber 415 which are arranged laterally. The left chamber 414 and the right chamber 415 are respectively connected to the upper joint chamber 411 and the lower joint chamber 412. A connecting hole 416 is located between the left chamber 414 and the right chamber 415.

[0058] The control piston 42 can be laterally reciprocated in the piston chamber 413. The right end of the control piston 42 is a radially outwardly protruding closed end 421. The closed end 421 can move back and forth left and right in the right chamber 415. A sealing ring O can be provided on the closed end 421. The leftward movement of the control piston 42 can drive the closed end 421 to block the connecting hole 416, thereby blocking the conduction between the upper joint chamber 411 and the lower joint chamber 412, that is, closing the internal water path S of the water outlet pipe valve core 4. The rightward movement of the control piston 42 can cause the closed end 421 to leave the connecting hole 416, thereby opening the internal water path S of the water outlet pipe valve core 4.

[0059] The left end of the control piston 42 is a stopper 422 whose outer diameter is smaller than the inner diameter of the connecting hole 416. The stopper 422 can pass through the left chamber opening 4141 at the left end of the left chamber 414 of the piston chamber 413 and be exposed on the left side of the valve core body 41, so that the stopper 422 can be pushed to the right by the tooth washer 1 inserted in the fixing device 31, thereby driving the closed end 421 to move right to open the internal water path S of the outlet pipe valve core 4.

[0060] Specifically, a transmission member 9 can be hinged between the valve core body 41 and the fixing device 31, and a movable hole 311 is provided on the side wall of the fixing device 31. The upper end of the transmission member 9 is hinged to the hinge hole 33 of the water outlet body 3, and the left side of the lower end of the transmission member 9 is a left contact portion 91 that can extend into the fixing device 31 from the movable hole 311, and the right side is a right contact portion 92 that abuts against the top portion 422 of the control piston 42. When the tooth washer 1 is inserted into the fixing device 31, the side wall of the tooth washer 1 squeezes the left contact portion 91 of the transmission member 9 out of the movable hole 311, and the transmission member 9 rotates to make the right contact portion 92 abut against the top portion 422 of the control piston 42 and move to the right, thereby driving the closed end 421 to move to the right, thereby realizing the opening of the internal water path S of the outlet pipe valve core 4.

[0061] At the same time, an ejection spring 43 is provided between the right end of the closed end 421 and the right chamber 415 of the piston chamber 413. When the tooth washer 1 is taken out from the fixing device 31, the left contact portion 91 of the transmission member 9 is not subjected to force, and the closed end 421 of the control piston 42 is moved to the left by the elastic force to close the connecting hole 416, thereby realizing the closure of the internal water path S of the water outlet valve core 4. At the same time, the top portion 422 moves to the left and extends out of the left chamber opening 4141 to push against the movement of the right contact portion 92 of the transmission member 9. The transmission member 9 rotates, so that the left contact portion 91 extends from the movable hole 311 into the fixing device 31.

[0062] In this embodiment, the top surface 93 of the left contact portion 91 of the transmission member 9 can be an inclined surface or an arc-shaped surface, so that the transmission member 9 can be smoothly squeezed out when the tooth washer 1 is inserted into the fixing device 31 to avoid getting stuck.

[0063] In order to prevent water leakage in the left chamber 414, a sealing ring O may be sleeved on the abutting top portion 422 inside the left chamber opening 4141, and a sealing ring O mounting groove may be recessed on the abutting top portion 422 to facilitate the fixing and assembly of the sealing ring O; and a retaining edge 4142 may be radially protruded from the inner wall of the left chamber opening 4141 to prevent the sealing ring O from falling out of the left chamber opening 4141. At the same time, in order to facilitate installation and assembly, a mounting hole 4151 may be provided at the right end of the right chamber 415, so that the control piston 42 can be inserted through the mounting hole 4151 and assembled in the right chamber 415 and the left chamber 414, and the mounting hole 4151 may be sealed and blocked by the mounting plate 417.

[0064] In this embodiment, by setting a transmission member 9 to cooperate with the control piston 42 to extend the abutting top 422 of the piston chamber 413, the rightward movement operation of the control piston 42 can be realized. Of course, other transmission methods can also be used. For example, the abutting top 422 extending out of the piston chamber 413 is replaced by an abutting top 422 with a magnetic attraction structure (not shown in the figure) that is movable in the left chamber 414 of the piston chamber 413, and the valve core body 41 is made to be close to the side wall of the fixing device 31, and then a circle of magnetic rings (not shown in the figure) is set at the corresponding position of the outer wall of the tooth washer 1. When the tooth washer 1 is inserted into the fixing device 31, the magnetic ring can magnetically repel the abutting top 422 with a magnetic attraction structure of the control piston 42, so as to achieve the purpose of moving the abutting top 422 and the closed end 421 to the right. In cooperation with the ejection spring 43, the opening and closing operation of the internal waterway S of the outlet pipe valve core 4 can also be realized.

[0065] Of course, the magnetic ring and the magnetic end may also attract each other, and the piston chamber 413 may be turned upside down and the closed end 421 may become the magnetic end.

[0066] like Figure 8 and Fig. 9 As shown, in order to ensure that the water pressure of the oral irrigator is not too high, a pressure reducing valve 7 can be provided between the water inlet mechanism 6 and the oral irrigator. In this embodiment, the pressure reducing valve 7 is provided at the lower joint of the four-way joint 63 of the water inlet mechanism 6.

[0067] The input end of the pressure reducing valve 7 is connected to the lower joint of the four-way joint 63 , and the output end of the pressure reducing valve 7 is connected to the pulling hose 81 .

[0068] For details, see Figures 9 to 12 As shown, the utility model provides a pressure reducing valve 7, including a valve seat 71, a valve core 72 and an elastic member 73.

[0069] The valve core 72 and the elastic member 73 are installed in the valve seat cavity 711 inside the valve seat 71; the two ends of the valve seat cavity 711 are respectively the valve seat water inlet end 712 and the valve seat water outlet end 713. The valve core 72 has a valve core channel 721 inside, and the two ends of the valve core channel 721 are respectively provided with a valve core water inlet end 722 and a valve core water outlet end 723 corresponding to the valve seat water inlet end 712 and the valve seat water outlet end 713.

[0070] The valve core 72 can reciprocate between the valve seat water inlet end 712 and the valve seat water outlet end 713 , and the elastic member 73 provides elastic force for the valve core 72 to move away from the valve seat water inlet end 712 . The elastic member 73 is a valve core spring 731 .

[0071] By this, after the water inlet end 712 of the upper valve seat of the pressure reducing valve 7 of the utility model is connected to the water inlet pressure of the water inlet mechanism 6 with a larger pressure, the water flows through the valve core water inlet end 722, the valve core channel 721 and the valve core water outlet end 723 in sequence, and can be output from the valve seat water outlet end 713 to the pull-out hose 81 with a smaller set water outlet pressure.

[0072] Specifically, when the water inlet pressure is relatively large or the pressure increases, the water pressure receiving area of ​​the valve core water inlet end 722 may be smaller than the water pressure receiving area of ​​the valve core water outlet end 723, which will cause the thrust acting on the valve core water outlet end 723 to change, thereby causing the valve core 72 to overcome the elastic force of the elastic member 73 and move toward the valve seat water inlet end 712, thereby reducing the water flow area between the valve seat water inlet end 712 and the valve core water inlet end 722, and ultimately adjusting the outlet water pressure to maintain a set value within a certain range, thereby achieving the functions of reducing pressure and stabilizing the outlet water pressure.

[0073] The outlet water pressure of the valve seat outlet end 713 of the pressure reducing valve 7 of the utility model is a set value within a certain range, and the set value can be adjusted by adjusting the elastic force of the valve core spring 731. When the elastic force of the valve core spring 731 is greater, the elastic force that the valve core 72 needs to overcome is greater, and the corresponding set value of the outlet water pressure is greater. The elastic force of the valve core spring 731 can be adjusted by setting the stiffness coefficient of the valve core spring 731 at the factory.

[0074] The valve seat water inlet end 712 of the valve seat 71 is also provided with an end cover 74, and the valve core 72 can reciprocate between the end cover 74 and the valve seat water outlet end 713, and the elastic member 73 provides elastic force for the valve core 72 to move away from the end cover 74; the end cover 74 has a shielding portion 741 directly opposite to the valve core water inlet end 722, and the end surface periphery of the valve core water inlet end 722 and the inner end surface periphery of the shielding portion 741 form a variable gap 75; the outer periphery of the shielding portion 741 has an end cover channel 742 that connects the outside and the variable gap 75.

[0075] The utility model provides an end cover 74 at the water inlet end 712 of the valve seat, and can utilize the shielding portion 741 of the end cover 74 to directly withstand the pressure of the water pressure of the water inlet. The end cover 74 can be made of high-strength material to withstand greater water pressure and be durable. The valve core 72 facing the shielding portion 741 will not be directly affected by the high-pressure water pressure on the water inlet side, thereby effectively improving the durability and service life of the pressure reducing valve 7.

[0076] In this embodiment, the outer periphery of the shielding portion 741 of the end cover 74 is the end cover outer edge 743 , and the end cover channel 742 can be five through holes 7421 circumferentially spaced on the end cover outer edge 743 , and the through holes 7421 pass through the front and rear ends of the end cover outer edge 743 .

[0077] In this embodiment, the valve seat includes a front joint 717 and a rear joint 718, and the front joint 717 and the rear joint 718 are rotatably engaged. The front end face of the front joint 717 is the valve seat water inlet end 712, and the rear end face of the rear joint 718 is the valve seat water outlet end 713. The valve core 72 and the elastic member 73 are installed in the valve seat cavity 711 formed between the front joint 717 and the rear joint 718.

[0078] The front inner wall of the valve seat cavity 711 near the valve seat water inlet end 712 radially protrudes a circle of retaining wall 714. The retaining wall 714 of this embodiment is located in the front joint 717. The front end surface of the retaining wall 714 near the valve seat water inlet end 712 forms an annular front retaining wall 7141, and the end cover channel 742 of the end cover outer edge 743 is opposite to the front retaining wall 7141. The front end portion 724 of the valve core where the valve core water inlet end 722 is located can be movably arranged in the middle of the retaining wall 714, so that the water pressure of the valve seat water inlet end 712 will not directly impact the valve core 72, but will impact the front retaining wall 7141 from the end cover channel 742 and then return to enter the variable gap 75.

[0079] At the same time, the inner diameter of the retaining wall 714 may not be larger than the outer diameter of the shielding portion 741 , so that the front end portion 724 of the valve core is completely shielded by the shielding portion 741 .

[0080] The rear end surface of the shielding portion 741 of the end cover 74 close to the valve core water inlet end 722 may be concavely provided with a receiving groove 7411, so that the water flow that impacts the front baffle wall 7141 can be turned back and enter the valve core water inlet end 722, thereby guiding the water flow.

[0081] The outer wall of the front end portion 724 of the valve core may be provided with a sealing ring O that seals with the inner wall of the retaining wall 714. Specifically, a sealing ring O is provided at intervals on the front and rear sides of the front end portion 724 of the valve core, so that the valve core 72 can maintain a sealing effect with the retaining wall 714 when it moves forward and backward, thereby facilitating the forward and backward movement of the valve core 72.

[0082] The rear end face of the retaining wall 714 is formed with an annular rear retaining wall 7142, and the outer wall of the rear end portion 725 of the valve core is radially protruding outward with a valve core retaining edge 726, and the outer wall of the valve core retaining edge 726 is sealed to fit the inner wall of the valve seat cavity 711 close to the valve seat water outlet end 713. Specifically, a sealing ring O may be provided on the outer wall of the valve core retaining edge 726 to seal with the inner wall of the valve seat cavity 711.

[0083] The elastic member 73 may be a valve core spring 731, which is sleeved on the valve core 72, and whose two ends respectively abut against a retaining edge front wall 7261 formed by the rear side of the rear retaining wall 7142 of the front retaining wall 714 and the front end surface of the valve core retaining edge 726, so as to push the valve core 72 to move in a direction away from the end cover 74.

[0084] When the valve core 72 is affected by the change in water pressure and continuously pushes against the compressed valve core spring 731, the water inlet end 722 of the valve core can eventually be brought into contact with the shielding portion 741 of the end cover 74, so that the size of the variable gap 75 becomes zero, thereby shutting off the water to the water inlet end 722 of the valve core. In the initial state, the valve core 72 is moved toward the water outlet end 713 of the valve seat by the action of the valve core spring 731, and the push limit is located at the inner end of the water outlet end 713 of the valve seat.

[0085] The valve core 72 of the present embodiment may be a columnar body with a radially outwardly convex rear end, so as to facilitate movement in the valve seat cavity 711; the valve core channel 721 runs through the interior and both ends of the columnar body, and the inner diameter of the valve core water outlet end 723 of the valve core channel 721 may be larger than the inner diameter of the valve core water inlet end 722, and the valve core water outlet end 723 is directly opposite to the valve seat water outlet end 713 to facilitate the outflow of water.

[0086] The end cover 74 of this embodiment can be made of a high-strength material alone, and snap-fitted to the front end of the front connector 717 .

[0087] At the same time, the outer contours of the front joint 717 and the rear joint 718 of this embodiment may respectively have hexagonal contour surfaces to facilitate the threaded connection of the front joint 717 and the rear joint 718.

[0088] In summary, the utility model adopts a purely mechanical structure, and utilizes the cooperation between the tooth washer 1 and the control piston 42 to realize a convenient water outlet operation of the tooth washer 1, and can ensure that the water supply pressure of the tooth washer 1 is sufficient, and can also avoid the situation where the water inlet mechanism 6 forgets to cut off the water, resulting in a long-term pressure buildup in the tooth washer 1, and protect the tooth washer 1 from being damaged by the high pressure at the front end for a long time. At the same time, a pressure reducing valve 7 is provided to avoid the situation where the water outlet pressure of the tooth washer 1 is too high.
