Description

Technical Field

[0001] The invention relates to a waterway switching structure. Background Art

[0002] Existing waterway switching structures typically include a main body, a switching seat, and a push-type drive mechanism. The main body generally has a switching chamber, a water inlet, and at least two water outlets, with the water inlet and outlets communicating with the switching chamber. The push-type drive mechanism typically employs a ballpoint pen-like push-type switching mechanism. Each press of the push-type drive mechanism causes the switching seat to rotate a predetermined angle, thereby switching the water inlet to communicate with each corresponding water outlet, achieving the water flow switching function. However, when actuating the existing switching seat, it is often necessary to overcome the reaction force of water pressure, resulting in a large driving force and a poor user experience. To address the problem of large driving force due to water pressure, the applicant has proposed a technical improvement, as shown in the Chinese utility model patent with patent publication number CN217108328U, entitled "A Push-Type Water-Saving Waterway Switching Structure." The technical solution disclosed in this patent eliminates the need to overcome water pressure when actuating the push-type drive mechanism, resulting in a labor-saving effect. However, the technical solution disclosed in this patent requires overcoming the friction of the seal 40 when actuating the push-type drive mechanism, resulting in a driving force that still needs to be further improved.

When the water hole corresponds to the water outlet hole, the water outlet hole is opened, and when the water hole is staggered with the water outlet hole, the water outlet hole is closed; the switching seat reset part adopts an elastic part or a magnetic part.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] The present invention designs the switching seat as follows: the switching seat includes a switching piece that cooperates with the switching surface, the switching seat can be rotatably arranged in the switching cavity and can move between a first position and a second position along the axial direction of its own rotation axis. In the first position, the switching piece is sealed and fit with the switching surface, and in the second position, the switching piece is separated from the switching surface. During the pressing process of the pressing drive mechanism, on the one hand, it drives the switching seat to rotate, and on the other hand, it drives the switching seat to move from the first position to the second position. In this way, once the switching piece leaves the first position, the water pressure on the side of the switching piece facing the switching surface and the water pressure on the side facing away from the switching surface can be balanced. Therefore, after the switching piece is separated from the switching surface, the rotation of the switching piece relative to the switching surface does not need to overcome the water pressure, and at the same time, there is no need to overcome the friction between the switching piece and the switching surface, which can save more effort, have a simple structure and reliable function.

[0027] When the pressing drive mechanism of the present invention is not pressed into place and the external force is removed, the pressing drive mechanism will not drive the switching seat to rotate in the opposite direction so that the switching seat can stay at any rotation angle. That is, it can be achieved that when the pressing drive mechanism was not pressed into place the previous time, the switching seat will not rotate and reset as the pressing drive mechanism is reset after being driven to rotate, but will remain at the angle corresponding to the pressing stroke of the pressing drive mechanism (that is, the greater the pressing stroke of the pressing drive mechanism, the greater the rotation angle of the switching seat where it stops). When the pressing drive mechanism is driven into place again for the next time, the switching seat will continue to rotate from the previous stop position until it rotates to a predetermined angle (that is, the next rotation angle of the switching seat = the predetermined angle - the previous rotation angle). That is to say, when the pressing drive mechanism is pressed, regardless of whether it is pressed in place or not, the switching seat can be rotated to an angle and stay at that angle. The angle is proportional to the pressing stroke. This is very suitable for application scenarios that require stepless control of the water flow rate of the water outlet. It is also suitable for adjusting the water outlet ratio between the two water outlets. Compared with the existing common ballpoint pen pressing drive mechanism whose water outlet device only has several fixed switching positions, the water outlet control of the present invention is more flexible and can achieve stepless water outlet adjustment.

[0028] The pressing drive mechanism of the present invention is designed to include a first switching shaft, a second switching shaft and a reset elastic member to achieve segmented drive, that is, the pressing stroke of the pressing drive mechanism has a first driving stroke and a second driving stroke. In the first driving stroke, the switching seat is rotated to a first angle by the inclined surface cooperation of the second switching shaft, and in the second driving stroke, the switching seat is rotated to a second angle by the inclined surface cooperation of the first switching shaft. There is no inclined surface cooperation between the switching seat and the sleeve, but an inclined surface cooperation is formed between the second switching shaft and the sleeve. In this way, the switching seat will not reversely rotate and reset after the external force is removed when the pressing drive mechanism is not pressed into place. The reverse rotation reset is replaced by the second switching shaft, so that the switching seat can stay at any rotation angle. The second switching shaft is set to replace the reverse rotation reset of the existing switching seat (when the pressing drive mechanism is not pressed into place) to achieve the purpose of the switching seat staying at any rotation angle. The conception is ingenious and the structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS

The reset elastic member 33 is used to provide a reset force to the first switching shaft 31 and the second switching shaft 32. The pressing stroke of the pressing drive mechanism 30 has a first driving stroke and a second driving stroke. In the first driving stroke, the first switching shaft 31 drives the second switching shaft 32 to slide axially along the first sliding groove 1212 of the shaft sleeve 121, and the second switching shaft 32 cooperates with the inclined surface of the rotating sleeve 22 to drive the rotating sleeve 22 to rotate a first angle; in the second driving stroke, the second switching shaft 32 exits the first sliding groove 1212 and enters the second sliding groove 222 of the rotating sleeve 22, and the first switching shaft 31 cooperates with the inclined surface of the rotating sleeve 22 to continue to drive the rotating sleeve 22 to rotate in the same direction by a second angle, and the sum of the first angle and the second angle is a predetermined angle; after the external force applied to the pressing drive mechanism 30 is removed, the second switching shaft 32 rotates relative to the shaft sleeve 121 and the rotating sleeve 22 under the action of the reset elastic member 33 and the cooperation with the inclined surface between the shaft sleeve 121 and slides back into the first sliding groove 1212 of the shaft sleeve 121.

[0056] Specifically, the inner wall of the shaft sleeve 121 is provided with a plurality of first protrusions 1211 arranged at equal intervals. The bottom surface of the first protrusion 1211 is formed with a first reset inclined surface 12111 , and a first sliding groove 1212 is formed between two adjacent first protrusions 1211 .

[0057] See also Figure 3 、 Figure 4 and Figure 6 The first switching shaft 31 is located at one end of the body 10 and is provided with a plurality of second protrusions 311 arranged at equal distances. The second protrusions 311 slide in the first sliding groove 1212 , and the bottom surface of the second protrusions 311 is formed with a first switching inclined surface 3111 .

[0058] See also Figure 3 and Figure 7 The outer wall of the second switching shaft 32 is provided with a plurality of third protrusions 321 arranged at equal distances. The top surface of the third protrusion 321 is formed with a second reset inclined surface 3211, and the bottom surface of the third protrusion 321 is formed with a second switching inclined surface 3212. In the first driving stroke, the third protrusion 321 slides in the first sliding groove 1212.

[0059] See also Figure 5 The inner circumferential wall of the rotating sleeve 22 is provided with a plurality of fourth protrusions 221 arranged at equal distances, the top surface of the fourth protrusion 221 is formed with a third switching inclined surface 2211, and a second sliding groove 222 is formed between two adjacent fourth protrusions 221. In the second driving stroke, the third protrusion 321 can slide into the second sliding groove 222, and the top end surface of the rotating sleeve 22 is formed with a plurality of fourth switching inclined surfaces 223 arranged at equal distances.

[0060] In the first driving stroke, the second switching inclined surface 3212 on the second switching shaft 32 cooperates with the third switching inclined surface 2211 of the rotating sleeve 22 to drive the switching seat 20 to rotate the first angle, and then the third protrusion 321 on the second switching shaft 32 slides into the second sliding groove 222, and makes the first switching inclined surface 3111 on the first switching shaft 31 correspond to the fourth switching inclined surface 223, and then in the second driving stroke, the first switching inclined surface 3111 on the first switching shaft 31 cooperates with the fourth switching inclined surface 223 to continue to drive the switching seat 20 is rotated in the same direction by a second angle, and the sum of the first angle and the second angle is a predetermined angle; after the external force applied to the pressing drive mechanism 30 is removed, the first switching shaft 31 and the second switching shaft 32 are reset under the action of the reset elastic member 33, and after the third protrusion 321 of the second switching shaft 32 slides out of the second sliding groove 222, the second reset inclined surface 3211 of the second switching shaft 32 abuts and cooperates with the first reset inclined surface 12111 of the shaft sleeve 121, and the second switching shaft 32 is rotated and reset, so that the third protrusion 321 slides back into the first sliding groove 1212;

[0064] The push-actuation mechanism 30 of this embodiment is an improvement on existing ballpoint pen push-actuation mechanisms. The primary difference is that this embodiment employs a phased push-actuation mechanism (including a first and second drive strokes), whereas existing ballpoint pen push-actuation mechanisms lack first and second drive strokes. This phased push-actuation mechanism allows the switch base 20 to remain in position at any rotational angle. Of course, in other embodiments, the push-actuation mechanism 30 may employ other common push-actuation mechanisms similar to those found in cylindrical pens, which are not detailed here.

[0065] In this embodiment, the top and bottom ends of the rotating sleeve 22 are respectively formed with openings.

[0067] In this embodiment, the switching plate 21 is an annular structure, and a water hole 211 is provided on the switching plate 21. When the water hole 211 corresponds to the water outlet hole 132, the water outlet hole 132 is opened, and when the water hole 211 and the water outlet hole 132 are staggered, the water outlet hole 132 is closed.

[0068] In this embodiment, the switch seat reset member 40 is an elastic member, specifically a compression spring. Alternatively, the switch seat reset member 40 may be a magnetic member (not shown), which uses the magnetic force of the magnetic member to reset the switch seat 20 from the second position to the first position. It is understood that the switch seat reset member 40 may also be other components capable of providing a reset force.

[0069] The following briefly describes the switching action of this embodiment:

[0070] like Figure 2 As shown, at this time, the portion of the first switching shaft 31 extending out of the body 10 (i.e., the driving portion of the driving mechanism) is not pressed. The second protrusion 311 on the first switching shaft 31 and the third protrusion 321 of the second switching shaft 32 are both located in the first sliding groove 1212 of the shaft sleeve 121. The second switching inclined surface 3212 of the second switching shaft 32 corresponds to and mates with the third switching inclined surface 2211 of the rotating sleeve 22. The first switching shaft 31 and the second switching shaft 32 are in contact with each other.

[0071] When the first switching shaft 31 is pressed into place, the first switching shaft 31 drives the second switching shaft 32 to overcome the elastic force of the reset elastic member 33 and move axially inward. Under the cooperation of the second switching inclined surface 3212 of the second switching shaft 32 and the inclined surface of the third switching inclined surface 2211 of the rotating sleeve 22, the switching seat 20 rotates forward by the first angle. Subsequently, the third protrusion 321 of the second switching shaft 32 slides into the second sliding groove 222 of the rotating sleeve 22. Since the switching seat 20 rotates by the first angle, at this time, the first switching of the first switching shaft 31 is The inclined surface 3111 corresponds to the fourth switching inclined surface 223 of the rotating sleeve 22. The first switching shaft 31 is continued to be pressed. Under the cooperation of the first switching inclined surface 3111 of the first switching shaft 31 and the inclined surface of the fourth switching inclined surface 223 of the rotating sleeve 22, the switching seat 20 continues to rotate in the same direction (forward) by a second angle. The first angle plus the second angle is the predetermined angle for each rotation of the switching seat 20. After the switching seat 20 rotates by the predetermined angle, the switching piece 21 switches to open the water outlet 132, so that the two water outlets 15 switch to discharge water.

[0072] When the driving external force applied to the first switching shaft 31 is removed, the first switching shaft 31 and the second switching shaft 32 are reset under the action of the reset elastic member 33. After the third protrusion 321 of the second switching shaft 32 slides out of the second sliding groove 222, the second reset inclined surface 3211 of the second switching shaft 32 abuts and cooperates with the first reset inclined surface 12111 of the shaft sleeve 121, and the second switching shaft 32 rotates and resets so that the third protrusion 321 slides into the first sliding groove 1212 again, so that the second switching inclined surface 3212 of the second switching shaft 32 corresponds to the third switching inclined surface 2211 of the rotating sleeve 22 again, that is, it returns to the position. Figure 2 The initial unpressed position shown is ready for the next switch.

[0073] When the first switching shaft 31 is not pressed into position, the switching seat 20 will stay at a rotation angle corresponding to the pressing stroke of the pressing drive mechanism 30 (the rotation angle is smaller than the predetermined angle) and will not rotate in the reverse direction to reset.
