Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom products, in particular to a pressing switching water outlet structure and a water outlet device. BACKGROUND

[0002] The existing pressing switching water outlet structure usually adopts a ball pen pressing rotation mechanism arranged between a water distribution disc and a switching shaft. Specifically, a first ratchet is arranged on the switching shaft, and a second ratchet is arranged on the water distribution disc. The pressing key is pressed to make the first ratchet press the second ratchet to move downward along a sliding groove. When the second ratchet is disengaged from the meshing position of the sliding groove, the radial force of the first ratchet on the second ratchet forces the water distribution disc to rotate, thereby realizing water path switching. In this scheme, the second ratchet on the water distribution disc needs to move along the sliding groove to realize the ratchet jump, which also means that the water distribution disc needs to move a long distance in the axial direction. The water distribution disc is subjected to the elastic force of the spring and the water flow pressure. During the pressing process, the resistance is large. Therefore, the user feels heavy when pressing the key, which is not convenient for user operation and the experience is poor. In addition, the cylindrical pen pressing rotation mechanism can only jump an angle of one ratchet at a time. With the increase of switching functions, the angle of rotation is smaller each time, which limits the size and position of the water distribution port, affecting the water passing area and the layout of the water outlet channel. SUMMARY

[0003] The present application discloses a pressing switching water outlet structure, which aims to improve the problems of heavy pressing feeling and limited water distribution port design of the existing pressing switching water outlet structure.

[0005] As a further improvement, the transmission member is provided with a transmission tooth, the water distribution disc is provided with an assembly hole, guide teeth are arranged on the inner wall of the assembly hole at intervals, the top of the guide tooth is provided with a guide surface for abutting against the transmission tooth, and the adjacent two guide teeth form a guide groove for embedding the transmission tooth.

[0008] As a further improvement, the bottom of the driving member is alternately provided with a driving tooth and a clamping groove along the circumferential direction, the driving tooth is provided with a first inclined surface arranged to abut against the transmission tooth, and the first inclined surface is arranged to extend along the inclined angle thereof to meet the second inclined surface on the clamping groove.

[0009] As a further improvement, the bottom surface of the driving tooth is provided with a protrusion arranged to abut against the pushing tooth, and the protrusion is arranged to be in the same shape as the bottom surface of the driving tooth.

[0012] As a further improvement, the water distribution disc has an outwardly extending circular boss, and the circular boss is provided with at least two water distribution openings.

[0013] The application further provides a water outlet device, which comprises a water outlet body and the press-switching water outlet structure according to any one of the above-mentioned embodiments, the water outlet body is provided with a water inlet channel communicated with the water inlet passage, and a water outlet channel communicated with each water outlet passage one by one, and the driving member is pressed in an operable manner to switch the water outlet channel communicated with the water inlet channel.

[0014] By adopting the above technical scheme, the application can achieve the following technical effects: 1. The application completes the skip tooth action of the transmission member relative to the driving member, so that the water distribution disc does not need to skip tooth during switching, thereby reducing the resistance of the driving member, and guaranteeing the pressing feeling.

[0021] In combination Figures 1 to 15 The present embodiment provides a pressing switch-out water structure, comprising a water outlet seat 1 and a water distribution disc 2, a driving piece 3 and a transmission piece 4 arranged on the water outlet seat 1; the water outlet seat 1 is provided with a water distribution cavity 11, a water inlet channel 12 and at least two water outlet channels 13 in communication with the water distribution cavity 11; wherein the water distribution disc 2 is arranged in the water distribution cavity 11 and has a pushing tooth 21 and a water distribution port 22 arranged through in the axial direction; by pressing the driving piece 3 to abut against the transmission piece 4 to move along the axial direction and drive the water distribution disc 2 to rotate, the pushing tooth 21 is correspondingly located at a position that can be pressed by the driving piece 3, so that when the driving piece 3 continuously moves along the axial direction to press the pushing tooth 21, the water distribution disc 2 is forced to rotate twice to be located at a preset angle, realizing the selective conduction of the water distribution port 22 with the water outlet channel 13, and at the same time assisting the transmission piece 4 to complete the tooth skipping action relative to the driving piece 3. For example, the driving piece 3 is pressed to abut against the transmission piece 4 to drive the water distribution disc 2 to rotate to a first angle, and in the process of continuous movement of the driving piece 3, the pushing tooth 21 is pressed to drive the water distribution disc 2 to rotate to a second angle, the directions of the first angle and the second angle are the same, and the sum of the two rotation angles is the preset angle of each rotation of the water distribution disc 2.

[0022] It should be noted that in the present embodiment, the tooth skipping action relative to the driving piece 3 is completed by the transmission piece 4, so that the water distribution disc 2 does not need to skip during switching, thereby reducing the resistance of the driving piece 3 to press down and guaranteeing the pressing feeling. At the same time, the arrangement of the pushing tooth 21 can assist the transmission piece 4 to skip smoothly, thereby further reducing the resistance to press down. In addition, when the driving piece 3 is pressed down, the transmission piece 4 drives the water distribution disc 2 to rotate for the first time, the driving piece 3 continuously presses down to drive the pushing tooth 21 to drive the water distribution disc 2 to rotate for the second time, so that the preset angle of the water distribution disc 2 is increased, and correspondingly the size of the water distribution port 22 can be made larger, which is also more conducive to the position setting of the water distribution port 22 and the layout of each water outlet channel 13.

[0023] In a preferred embodiment, the transmission member 4 is provided with a transmission tooth 41, the water distribution tray 2 is provided with an assembly hole 23, and guide teeth 231 are arranged on the inner wall of the assembly hole 23 at intervals. The top of the guide teeth 231 is provided with a guide surface 2311 for abutting against the transmission tooth 41, and a guide groove 232 is formed between two adjacent guide teeth 231 for the transmission tooth 41 to be inserted into. When the transmission member 4 is pressed down, the transmission tooth 41 abuts against the guide surface 2311 to drive the water distribution tray 2 to rotate, and after the transmission tooth 41 falls into the guide groove 232 along the guide surface 2311, the first rotation of the water distribution tray 2 is completed.

[0024] Preferably, the transmission tooth 41 is arranged at intervals along the outer periphery of the transmission member 4, and has a cross-sectional shape tending to be a parallelogram, the top of which abuts against the driving member 3, and the bottom of which abuts against the guide tooth 231. The top and the bottom of the transmission tooth 41 are both arranged as inclined surfaces, the inclined surface of the top ensures that the transmission member 4 can perform a skip tooth action, and the inclined surface of the bottom can cooperate with the guide surface 2311 to drive the water distribution tray 2 to rotate.

[0025] In another embodiment, the top of the water distribution tray 2 is provided with the same number of push teeth 21 as the guide teeth 231 in the circumferential direction of the assembly hole 23, and each push tooth 21 is arranged in a staggered manner with each guide tooth 231. The guide teeth 231 are arranged on the inner wall of the assembly hole 23, and the push teeth 21 are arranged on the top of the water distribution tray 2, so that the structure is more compact, which is conducive to reducing the volume of the pressing switch water outlet structure.

[0026] Further, the bottom of the driving member 3 is alternately provided with a driving tooth 31 and a clamping groove 32 in the circumferential direction, the driving tooth 31 is provided with a first inclined surface 311 for abutting against the transmission tooth 41, and the first inclined surface 311 is arranged to extend along its inclined angle to meet the second inclined surface 321 on the clamping groove 32. The inclined angles of the first inclined surface 311 and the second inclined surface 321 are similar, so as to ensure smooth skip tooth action of the transmission tooth 41.

[0027] In one embodiment, the bottom surface of the driving tooth 31 is provided with a protrusion 312 for abutting against the push tooth 21, which is arranged in a shape following the bottom surface of the driving tooth 31, so as to ensure that the protrusion 312 can abut against the push tooth 21 smoothly in the state that the driving tooth 31 abuts against the transmission tooth 41, avoiding being affected by the transmission tooth 41, and ensuring the rotation angle of the water distribution tray 2 in the second time.

[0028] On the basis of the above-mentioned embodiments, in an optional embodiment of the present application, a first elastic member 5 is arranged between the water distribution disc 2 and the bottom surface of the water distribution cavity 11, a second elastic member 6 is arranged between the transmission member 4 and the bottom surface of the water distribution cavity 11, the water outlet seat 1 is provided with a mounting hole 14, a guide rail 141 and a sliding groove 142 are arranged along the inner wall of the mounting hole 14, the driving member 3 is sleeved in the mounting hole 14, the driving teeth 31 are embedded in the sliding groove 142, and the bottom surface of the guide rail 141 is provided with a reset inclined surface 1411 for driving the transmission member 4 to rotate. The first elastic member 5 and the second elastic member 6 are preferably springs. Under the action of the first elastic member 5, the water distribution disc 2 is kept in close contact with the sealing member 7 to ensure the water distribution effect. During installation, the driving member 3 and the transmission member 4 are sequentially sleeved into the mounting hole 14, and the driving teeth 31 and the transmission teeth 41 are embedded in the sliding groove 142. The assembly hole 23 on the water distribution disc 2 is sleeved into the transmission member 4, and the guide teeth 231 are aligned with the transmission teeth 41.

[0029] With reference to Figure 15 , the driving member 3 is pressed, the driving teeth 31 abut against the transmission teeth 41, at this time, the driving teeth 31 and the transmission teeth 41 are both located in the sliding groove 142, so as to move downward along the sliding groove 142, the bottom of the transmission teeth 41 abuts against the guide teeth 231, so that the water distribution disc 2 rotates, and when the transmission teeth 41 fall into the guide groove 232, the first rotation of the water distribution disc 2 is completed; the driving member 3 continuously moves downward, the driving teeth 31 abut against the pushing teeth 21, so as to push the water distribution disc 2 to drive the transmission member 4 to rotate synchronously, when the top of the transmission teeth 41 is separated from the sliding groove 142, it slides to the second inclined surface 321 along the first inclined surface 311 of the driving teeth 31 under the elastic force of the second elastic member 6 and the auxiliary action of the pushing teeth 21, and is abutted in the clamping groove 32 to complete the skip tooth action, at this time, the second rotation of the water distribution disc 2 is completed, and the transmission teeth 41 are aligned with the guide rail 141. After the driving member 3 is released, the second elastic member 6 abuts against the transmission member 4 to drive the driving member 3 to move upward along the sliding groove 142, when the transmission member 4 moves to abut against the guide rail 141, it slides into the adjacent sliding groove 142 under the action of the reset inclined surface 1411, that is, it returns to the state before the driving member 3 is pressed, so as to prepare for the next pressing.

[0030] Preferably, the transmission teeth 41, the guide teeth 231, the pushing teeth 21, the driving teeth 31 and the guide rail 141 are all arranged in the same number, which is beneficial to the transmission cooperation of the teeth and ensures the stable switching process. Different angles of switching are realized by arranging different numbers of teeth, so that the design of the water distribution port 22 is more flexible.

[0031] In other embodiments, the water distribution disc 2 has a circular boss extending outward, and the circular boss is provided with at least two water distribution ports 22. For example, with reference to Figures 1 to 8The water outlet seat 1 is provided with two water outlet channels 13, which are a first water outlet channel 131 and a second water outlet channel 132, respectively, and the water distribution disc 2 is provided with two water distribution openings 22, which are a first water distribution opening 221 and a second water distribution opening 222, respectively. The number of teeth of various teeth is set to four, and each pressing of the driving piece 3 makes the water distribution disc 2 rotate by 90°, realizing a first water outlet mode in which the first water distribution opening 221 and the second water distribution opening 222 are both in communication with the first water outlet channel 131, a second water outlet mode in which the first water distribution opening 221 is in communication with the second water outlet channel 132 and the second water distribution opening 222 is in communication with the first water outlet channel 131, a third water outlet mode in which the first water distribution opening 221 and the second water distribution opening 222 are both in communication with the second water outlet channel 132, and a fourth water outlet mode in which the second water distribution opening 222 is in communication with the second water outlet channel 132 and the first water distribution opening 221 is in communication with the first water outlet channel 131. The four water outlet modes are switched in turn by pressing the driving piece 3. The second water outlet mode and the fourth water outlet mode have the same water outlet effect, so that the control of three different water outlet effects, i.e., the first water outlet channel 131 water outlet, two-channel simultaneous water outlet and the second water outlet channel 132 water outlet, can be realized. By analogy, Figures 10 to 14 Three water outlet channels 13 are provided, which are a first water outlet channel 131, a second water outlet channel 132 and a third water outlet channel 133, respectively, and the number of teeth of various teeth can be set to three, and the preset rotation angle of the water distribution disc 2 is 120°, so that a first water outlet mode in which the first water distribution opening 221 and the second water distribution opening 222 are both in communication with the first water outlet channel 131, a second water outlet mode in which the first water distribution opening 221 is in communication with the second water outlet channel 132 and the second water distribution opening 222 is in communication with the third water outlet channel 133, and a third water outlet mode in which the first water distribution opening 221 and the second water distribution opening 222 are both in communication with the third water outlet channel 133 can be formed.
