Example one

Example one relates to a foaming device 100 and a water outlet device 1000. The foaming device 100 is used for connecting to the water outlet pipe 200 of the water outlet device 1000 (see fig. 11).

See fig. 1-3. As shown, the frothing device 100 comprises a connecting assembly 10 and a bubbler 3. The connecting assembly 10 includes a mount 1 and a slider 2.

The shape and structure of the mount 1 are shown in fig. 4 and 5. As shown in the drawings, the mount 1 includes a mount body 11 and a mount cover 12. In fig. 4, the mount body 11 includes a housing 111, a mount ring 112, and a plurality of connecting ribs 113. The housing 111 is located at the center of the mounting seat body 11, a mounting ring 112 coaxially surrounds the housing 111, and each connecting rib 113 radially extends to connect the housing 111 and the mounting ring 112 into a whole. The mounting ring 112 is shown in fig. 4, and has an outer wall provided with external threads that mate with internal threads on the inner wall of the outlet pipe 200. The intervals between the respective ribs 113 form a plurality of water passing holes 114. In the present embodiment, the water through holes 114 are radially and symmetrically provided around the housing 111 so that a user can insert a fork tool therebetween symmetrically, fit the mounting ring 112 to the inner wall of the outlet pipe 200 and tighten it. The housing 111 is generally annular in structure as shown in fig. 5, and has a stepped hole along the axial direction, wherein the large hole is located above the small hole, and an upward limiting surface 133 is arranged between the large hole and the small hole. As shown in fig. 4 and 5, the mounting seat cover 12 is disposed on the upper end of the housing 111, and is connected to the housing 111 in a snap fit manner. After the cover 12 is connected to the housing 111, a seat 13 with a downward opening is formed. The holder body 13 is shaped like a cylinder, and the cylindrical cavity of the holder body 13 is divided into two parts by the limiting surface 133, wherein the part above the limiting surface 133 forms the first chamber 131, and the part below the limiting surface 133 forms the second chamber 132. Since the housing 111 is coaxial with the mounting ring 112, and the mounting ring 112 is screw-fitted with the outlet pipe 200, the axis of the seat body 13 coincides with the axis of the outlet pipe 200. The top surface of the mounting seat cover 12 forms a first stop position of the seat body 13, and the limiting surface 133 on the mounting seat body 11 forms a second stop position of the seat body 13.

The slide block 2 includes a slide block 21, a latch 22, and a screw 23 as shown in fig. 3. The structure of the slider 21 is shown in fig. 6. As shown in fig. 6, the slider 21 has a cylinder 211 with an upward opening, the bottom of the cylinder 211 extends downward and is protruded with a connection part 212, and the upper end of the outer wall of the cylinder 211 is protruded with a boss 213. The lower surface of the boss 213 forms a stepped surface 214. A connection hole 215 is provided in the center of the slider 2 so as to penetrate the connection portion 212 and the bottom of the cylindrical body 211, and the connection hole 215 is provided with an internal thread. The outer wall of the boss 213 is provided with a seal ring groove, and a seal ring 216 is arranged in the seal ring groove. The shape of the latch 22 is shown in fig. 7. As shown in fig. 7, the latch 22 is provided with a cylindrical body 221, and the diameter of the body 221 is substantially the same as that of the cylindrical body 211 of the slider 21. Four elastic claws 223 are arranged on the lower surface 222 of the body along the circumferential direction around the axis, the elastic claws 223 are opened outwards under the state of not being pressed, and the free end of the elastic claws 223 is provided with a chuck 224 extending inwards. The body 221 has a through hole in the center. The shape of the screw 23 is shown in fig. 3.

The shape of the bubbler 3 is shown in figure 8. As shown in fig. 8, the bubbler 3 is provided with a push rod 31 extending upward, and a locking groove 32 is provided on a side wall of the push rod 31. The bubbler side wall 33 is provided with an upwardly opening lip seal 34. The upper surface of the bubbler 3 is provided with a water inlet, and the lower surface is provided with a water outlet. The water inlet is adapted to introduce a flow of water through the water through holes 114 and the water outlet is adapted to output bubble water. Since the construction of the bubbler 3 is known and not modified by the present application, it will not be described in detail.

The state of the foaming device 100 after the completion of the connection is shown in fig. 9. Wherein, the screw 23 passes through the through hole on the fixture block 22 and is screwed with the connecting hole 215 on the slide block 21 to fasten the slide block 21 and the fixture block 22 together. The boss 213 of the slider 21 is located in the first chamber 131 of the housing 13, and the cylinder 211 of the slider 21 and the body 221 of the latch 22 extend into the second chamber 132 of the housing 13. The outer wall of the boss 213 is in sliding clearance fit with the side wall of the first chamber 131 with the sealing ring 216 interposed therebetween to increase the friction between the two, enabling the slide 213 to rest. The barrel 211 and body 221 are in sliding clearance fit with the side wall of the second chamber 132. Thereby, the sliding connection relationship between the sliding block 2 and the seat body 13 is established. In fig. 9, the sliding block 2 is at the first position, the upper end surface of the sliding block 21 abuts against the bottom surface of the mounting seat cover 12 (i.e. the first stop position of the seat body 13), the elastic claw 223 retracts into the second cavity 132 of the seat body 13, due to the pressing of the side wall of the second cavity 132 against the outer edge surface of the elastic claw 223, the elastic claw 223 is folded inward and establishes a snap-fit relationship with the snap-fit groove 32 of the bubbler 3, and the bubbler 3 is fixed relative to the mounting seat 1 due to being caught by the elastic claw 223. At this time, the slider 2 does not slide down due to the gravity of the bubbler 3 and the pressure of the water flow due to the friction of the sealing ring 216.

In the foaming device 100, a state in which the connection assembly 10 is separated from the bubbler 3 is shown in fig. 10. In fig. 10, the sliding block 2 is at the second position, the step surface 214 of the boss 213 abuts against the limiting surface 133 of the seat body 13 (i.e. the second stop position of the seat body 13), the elastic claw 223 completely extends out of the second cavity 132 of the seat body 13, and due to the loss of the abutting pressure of the side wall of the second cavity 132, the elastic claw 223 is deformed and restored to be opened outward, and is separated from the clamping relationship with the clamping groove 32 of the bubbler 3, and the bubbler 3 is released due to the loss of the clamping of the elastic claw 223.

The connection assembly 10 is assembled by first placing the slider 21 into the large hole from the top of the mount base body 11 with the connection portion 212 facing downward, and then engaging the mount base cover 12 with the mount base body 11. The latch 22 is inserted into the second chamber 132 with the body 221 facing upward, and the latch 22 is coupled to the slider 21 with the screw 23. At this point, the connection assembly 10 is assembled.

The shape of the water outlet device 1000 is shown in fig. 11. As shown in fig. 11, the water outlet device 1000 includes a water outlet pipe 200 and a foaming device 100. The connection of the outlet pipe 200 to the frothing device 100 is shown in fig. 12 and fig. 13. As shown in fig. 12 and 13, a position of the outlet pipe 200 near the water inlet end and the water outlet end is provided with a limiting ring 201, a water through hole 202 is provided in the center of the limiting ring 201, and an internal thread is provided on the inner wall of the outlet pipe 200 below the limiting ring 201. The external thread of the mounting ring 112 of the connecting assembly 10 is screwed with the internal thread of the water outlet pipe 200, so as to fixedly connect the mounting seat 1 and the water outlet pipe 200 together. In fig. 12, the slider 2 is in the first position, and at this time, the bubbler 3 is captured by the elastic claw 223, one part of which is located in the water outlet pipe 200, the other part of which is located outside the water outlet pipe 200, and the lip-shaped sealing ring 34 is located in the water outlet pipe 200, so that the bubbler 3 and the water outlet pipe 200 are connected in a sealing manner without water leakage. In fig. 13, slider 2 is in the second position, in which bubbler 3 is released by resilient jaws 223, the majority of which is located outside outlet pipe 200, a small portion of which is located inside outlet pipe 200, and lip seal 34 is located outside outlet pipe 200.

The method of mounting the connection assembly 10 to the outlet pipe 200 is as follows: first, the assembly of the connection assembly 10 is completed, and then the connection assembly 10 is inserted into the outlet pipe 200 in a posture in which the mount cover 12 is upward. Until the external thread of the mounting ring 112 touches the internal thread of the outlet pipe 200. The fork-shaped mounting tool is inserted into the symmetrical water through holes 114, and is rotated until the upper end surface of the mounting ring 112 abuts against the lower surface of the limiting ring 201, so that the threaded connection between the mounting ring 112 and the water outlet pipe 200 is completed, and the connecting assembly 10 is mounted to the water outlet pipe 200.

The method of connecting bubbler 3 to connection assembly 10 is as follows: the bubbler 3 is inserted into the water outlet pipe 200 with the push rod 31 facing upward, and the push rod 31 abuts against the lower surface 222 of the body of the latch 22, at this time, the state is shown in fig. 13. The bubbler 3 continues to be pushed upwards, so that the push rod 31 pushes the sliding block 2 to move upwards until the sliding block 2 moves to the first position, and the state at this time is shown in fig. 12, and the connection of the bubbler 3 is completed. After the bubbler 3 is connected, the valve of the water outlet device 1000 is opened, water flows through the water through hole 202 on the limiting ring 201, then through the water through hole 114 to reach the water inlet of the bubbler 3, and then flows out of the water outlet of the bubbler 3 after passing through the bubbler 3. Since the lip seal 34 is interposed between the side wall 33 of the bubbler and the inner wall of the outlet pipe 200, water does not flow out through a gap therebetween.

The method of removing the bubbler 3 from the connection assembly 10 is as follows: the bubbler 3 is grasped to expose the portion of the water outlet pipe 200, and pulled downward, so that the bubbler 3 drives the sliding block 2 to move downward until the sliding block 2 moves to the second position, which is shown in fig. 13. The bubbler 3 is continuously pulled down to completely separate the bubbler 3 from the water outlet pipe 200, and the detachment of the bubbler 3 is completed. Bubbler 3 is removed and back flushed and then connected to connector assembly 10 by the steps described above.

Of course, this embodiment is not the only one, and especially, a downwardly extending pull ring may be provided on the lower surface of the bubbler 3, so that the screw-connection position of the mounting ring 112 and the outlet pipe 200 may be set, and the water outlet of the bubbler 3 is located in the outlet pipe 200, without affecting the user's removal of the bubbler 3. In particular, the bubbler 3 may be removed from the outlet pipe 200 by pulling the aforementioned pull-tab.

As can be seen from the above description, the present embodiment can easily detach the bubbler 3 from the outlet pipe 200.

The lower end surface of the convex ring 43 is provided with an inner inclined surface 46; the lower end face of the projection 44 is provided with an outer bevel 47, in this embodiment the inner bevel 46 and the outer bevel 47 are in the same plane, but the function is different and not necessary. The inner slope 46 is opposite the third slope 218, and the outer slope 47 is opposite the first slope 138 and the second slope 136.

The elastic member 5 in this embodiment includes a spring 51 and a spacer 52 as shown in fig. 3.

The assembled construction of the connector assembly 10 is shown in fig. 19 and 20. As shown, as in the first embodiment, the boss 213 of the slider 21 is located in the first chamber 131 of the housing 13, and the cylinder 211 of the slider 21 and the body 221 of the latch 22 extend into the second chamber 132 of the housing 13. The outer wall of the boss 213 is in sliding clearance fit with the side wall of the first chamber 131, and the cylinder 211 and the body 221 are in sliding clearance fit with the side wall of the second chamber 132, so that the sliding block 2 and the base body 13 are in sliding connection. The difference between this embodiment and the first embodiment is that the rotation stopping block 217 extends into the rotation stopping groove 135 of the seat body 13, so that the rotation stopping fit relationship between the sliding block 2 and the seat body 13 is also established. In this embodiment, the hooking portion 45 of the rotating sleeve 4 is hooked with the hooking portion 219 of the slider 21, so that an axial limit connection is established between the rotating sleeve 4 and the slider 2, that is, the position between the rotating sleeve 4 and the slider is limited, and when the position between the rotating sleeve 4 and the slider reaches the maximum value of the limited range, a force transmission is established between the rotating sleeve 4 and the slider. In this embodiment, the lower end surface of the spacer 52 abuts against the upper end surface of the hooking portion 219 of the slider 21. One end of the spring 51 abuts against the mounting seat cover 12, and the other end abuts against the upper end face of the gasket 52.

The connecting assembly 10 is assembled by first inserting the slider 21 into the large hole from the top of the mount body 11 with the connecting portion 212 facing downward, and inserting the detent 217 into the detent groove 135. The rotary sleeve 4 is inserted into the cylindrical cavity of the cylindrical body 211 of the slider 21 with the hook portion 45 facing downward until the hook portion 45 is hooked to the hook portion 219. The washer 52 is then placed on the upper end surface of the hanging portion 219 through the center hole 42 of the rotating sleeve 4. The lower end of the spring 51 is pushed against the upper end face of the washer 52 through the center hole 42 of the rotating sleeve 4. Then, the mounting seat cover 12 is clamped with the mounting seat body 11, so that the upper end of the spring 51 abuts against the mounting seat cover 12. The latch 22 is inserted into the second chamber 132 with the body 221 facing upward, and the latch 22 is coupled to the slider 21 with the screw 23. At this point, the connection assembly 10 is assembled.

In this embodiment, the bubbler 3 is not different from the bubbler 3 of the first embodiment, and will not be described herein.

Fig. 19 shows the structure of the bubble device 100 in this embodiment when the sliding block 2 is in the first position. As shown in fig. 19, the protrusion 44 of the rotating sleeve 4 stops at the tooth bottom 137 with a higher position, because the sliding block 2 and the rotating sleeve 4 are axially connected in a limited manner, and the sliding block 2 is pushed downward by the elastic member 5, the sliding block 2 stops at the first position, and the elastic claw 223 retracts into the second chamber 132, because the side wall of the second chamber 132 presses against the outer edge surface of the elastic claw 223, the elastic claw 223 draws inward, and establishes a snap-fit relationship with the snap groove 32 of the bubbler 3, and the bubbler 3 is fixed relative to the mounting base 1 because of being caught by the elastic claw 223.

Fig. 20 shows the structure of the foaming device 100 in this embodiment when the sliding block 2 is in the first position. As shown in fig. 20, at this time, the protrusion 44 of the rotating sleeve 4 stops at the lower rotation stopping groove 135, because the sliding block 2 and the rotating sleeve 4 are axially connected in a limited manner, and the sliding block 2 is pushed by the elastic member 5 downward, the sliding block 2 stops at the second position, at this time, the elastic claw 223 completely extends out of the second cavity 132 of the seat body 13, and because the pushing pressure of the side wall of the second cavity 132 is lost, the elastic claw 223 is deformed and restored to be opened outward, and is separated from the clamping relationship with the clamping groove 32 of the bubbler 3, and the bubbler 3 is released because the clamping of the elastic claw 223 is lost.

The method of switching the slider 2 between the first position and the second position is explained in detail below.

The initial position is set such that the slide block 2 is in the second position as shown in fig. 20, and the mount 1 is set to be stationary. At this time, the top bar 31 of the bubbler 3 is pressed against the lower surface 222 of the body, and the elastic claws 223 are in an open state but face the locking grooves 32 on the top bar 31. If a user wants to connect the bubbler 3 to the connecting assembly 10, he can push the bubbler 3 upwards, the push rod 31 pushes the sliding block 2 upwards against the elastic force of the elastic member 5 until the third inclined surface 218 pushes the inner inclined surface 46, the third inclined surface 218 is opposite to the inner inclined surface 46, so that the inclined surfaces are matched to convert the axial pushing force into a rotating force, and the sliding block 2 is in rotation-stopping fit with the mounting seat 1, so that the rotating sleeve 4 is forced to rotate and moves upwards during the rotation process. During this process, the resilient latch 223 has retracted into the second chamber 132, establishing a snap-fit relationship with the latch slot 32. The user no longer pushes up bubbler 3, the elastic restoring force of elastic component 5 acts on, drive sliding block 2 moves down, after the distance between sliding block 2 and rotating sleeve 4 reaches the limit, sliding block 2 drives rotating sleeve 4 to move down until outer inclined plane 47 pushes up to second inclined plane 136, because second inclined plane 136 is opposite to outer inclined plane 47, this inclined plane cooperation, convert axial top to the rotational force, consequently force rotating sleeve 4 to rotate and in the course of rotating upward movement, until protrusion 44 slips into the tooth bottom 137 and stops at the tooth bottom 137 (namely first stops the position). At this time, because the sliding block 2 is axially and limitedly connected with the rotating sleeve 4, the sliding block 2 stops at the first position, and the bubbler 3 is caught by the connecting component 10.

If the user wants to remove the bubbler 3 from the connecting assembly 10 and also pushes the bubbler 3 upwards, the push rod 31 pushes the sliding block 2 upwards against the elastic force of the elastic member 5 until the third inclined surface 218 pushes the inner inclined surface 46, the inclined surfaces are matched because the third inclined surface 218 is opposite to the inner inclined surface 46, the axial pushing force is converted into a rotating force, and the sliding block 2 is in rotation-stopping fit with the mounting seat 1, so that the rotating sleeve 4 is forced to rotate and moves upwards in the rotating process. In this process, the elastic claw 223 is always engaged with the engaging groove 32. The user no longer pushes up and supports bubbler 3, the elastic restoring force of elastic component 5 acts on, drive sliding block 2 downstream, after the distance of sliding block 2 and rotating sleeve 4 reached the limit, sliding block 2 drove rotating sleeve 4 downstream, until outer inclined plane 47 switches to support and presses to first inclined plane 138, because the outer inclined plane 47 of first inclined plane 138 is relative, therefore this inclined plane cooperation, convert axial top to the power of rotating, consequently force rotating sleeve 4 to rotate and at the in-process upward movement of rotating, until protruding 44 slips into only rotating groove 135 and stop in only rotating groove 135 (the second stops the position promptly), be located only rotating block 217 top. The rotation stop block 217 abuts against the limiting surface 133. The slider 2 now rests in the second position. In the above process, the elastic latch 223 extends out of the second chamber 132 and is opened outward to be disengaged from the latch groove 32, and the bubbler 3 is separated from the connecting assembly 10.

The shape of the water outlet device 1000 is shown in fig. 21. As shown in FIG. 21, the outlet device 1000 comprises an outlet pipe 200 and a foaming device 100, wherein the foaming device 100 is completely arranged in the outlet pipe 200 and cannot be seen from the appearance. The connection of the outlet pipe 200 to the frothing device 100 is shown in fig. 22. As shown in fig. 22, a position of the outlet pipe 200 near the water inlet end and the water outlet end is provided with a limiting ring 201, the center of the limiting ring 201 is provided with a water through hole 202, and an inner thread is arranged on the inner wall of the outlet pipe 200 below the limiting ring 201. The external thread of the mounting ring 112 of the connecting assembly 10 is screwed with the internal thread of the water outlet pipe 200, so as to fixedly connect the mounting seat 1 and the water outlet pipe 200 together. At this point, bubbler 3 may be connected to or disconnected from connector assembly 10 in the manner previously described. Fig. 21 shows a simple procedure for establishing a connection with the connection assembly 10. After this process, the slider 2 is in the first position, where the bubbler 3 is gripped by the elastic jaws 223 and is entirely inside the outlet pipe 200. If the user wants to remove bubbler 3 from outlet pipe 200 for cleaning, he simply presses up on bubbler 3, as previously described, which releases bubbler 3 by means of resilient catch 223, and at this point, since slide 2 is in the second, lower position, bubbler 3 is pushed down by lower surface 222 of the body, at least a portion of which is exposed outside outlet pipe 200, and lip-seal 34 is also located outside outlet pipe 200. This is the state shown in the middle of fig. 22. The user simply pulls the bubbler 3 slightly out of the outlet pipe 200.

In this embodiment, the process of installing the connection assembly 10 to the water outlet pipe 200 is completely the same as the installation process of the first embodiment, and is not described herein again.

As can be seen from the above description, in the present embodiment, by providing the ball-point pen bouncing mechanism, the foam maker 3 can be switched between being grasped and being released by the pressing and releasing actions, so that the foam maker 3 can be taken down from the water outlet pipe by the action of pushing against the foam maker from above and releasing, and therefore, the foam maker 3 can be integrally hidden in the water outlet pipe 200 when the connection is completed, so as to avoid a seam from being formed between the foam maker 3 and the water outlet pipe 200.

Of course, similar ball point pen bouncing mechanisms have many variations, not all of which are described herein. The biggest contribution of the embodiment is to combine the extension and retraction of the elastic claw 223 relative to the seat body 13 and the structure of the bouncing mechanism of the ball pen, thus solving the problem that the bubbler 3 is arranged in the water outlet pipe 200, and being convenient to install and remove.

The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting.
