DETAILED DESCRIPTION

[0038] In this embodiment, if Figures 1 to 14The soap dispenser shown in the figure can be automatically sealed when the liquid storage bottle is removed, and the soap dispenser includes a housing 1, a fixing seat 3, a pump head 5 and a liquid storage bottle 2, wherein the liquid storage bottle 2 is installed at one end inside the housing 1, and the pump head 5 is installed at the other end of the housing 1, and the pump head 5 is installed on the fixing seat 3, and the liquid inlet pipe 51 of the pump head 5 is connected to the liquid storage bottle 2 and the liquid outlet pipe 52 of the pump head 5 passes through the housing 1; a stop valve is arranged in the liquid storage bottle 2, and the stop valve includes a positioning cover 22 and a stop valve stem 26; the positioning cover 22 is installed on the bottleneck 21 of the liquid storage bottle 2 , a butt joint pipe 221 is arranged on one side of the positioning cover 22 close to the liquid inlet pipe 51, and the liquid inlet pipe 51 is located in the butt joint pipe 221; the stop valve stem 26 is arranged on the other side of the positioning cover 22, and when the liquid storage bottle 2 is separated from the pump head 5, the stop valve stem 26 is pressed against and sealed against the butt joint pipe 221 through the third elastic member 27; when the liquid storage bottle 2 is connected to the pump head 5, the liquid inlet pipe 51 pushes the stop valve stem 26 away from the butt joint pipe 221, and the liquid inlet pipe 51 is connected to the inner cavity of the liquid storage bottle 2 through the butt joint pipe 221. When the liquid storage bottle 2 is removed to replenish the cleaning liquid, after the liquid storage bottle 2 is separated from the pump head 5, the stop valve stem 26 is pressed against and sealed against the butt joint pipe 221 through the third elastic member 27, so that the inner cavity of the liquid storage bottle 2 is isolated from the outside, and the residual liquid in the liquid storage bottle 2 will not flow out, and after the cleaning liquid is replenished, the liquid storage bottle 2 can be directly installed upside down in the housing 1, without worrying about the problem of pouring out the cleaning liquid, and it is more convenient and quick to use.

[0039] In this embodiment, if Fig.10 and 13 As shown, a limiting cover 25 is concentrically arranged on one side of the butt joint pipe 221 away from the pump head 5, a stop valve stem 26 is arranged between the butt joint pipe 221 and the limiting cover 25, and a third elastic member 27 is arranged between the stop valve stem 26 and the limiting cover 25; a plurality of liquid inlet holes are provided on the limiting cover 25, and the liquid in the liquid storage bottle 2 enters the butt joint pipe 221 through the liquid inlet holes. The stop valve stem 26 includes a tapered section 261, an overflow section and a straight rod section 262, and the outer diameter of the large end of the tapered section 261 is larger than the inner diameter of the butt joint pipe 221; one end of the straight rod section 262 away from the tapered section 261 passes through the limiting cover 25, and a third elastic member 27 is sleeved on the straight rod section 262, and the third elastic member 27 is located between the limiting cover 25 and the tapered section 261. The overflow section is arranged on the end face of the small end of the conical section 261; an overflow groove 2611 is opened on the overflow section, the outer diameter of the overflow section is equal to the inner diameter of the butt joint pipe 221 and is located inside the butt joint pipe 221. When the liquid storage bottle 2 is installed on the pump head 5, the pipe mouth of the liquid inlet pipe 51 is connected with the interior of the liquid storage bottle 2 through the overflow groove 2611.

[0040] In this embodiment, the butt joint 221 and the bottleneck 21 are concentrically arranged, and a sealing ring is mounted on the liquid inlet pipe 51. The outer diameter of the liquid inlet pipe 51 is slightly smaller than the inner diameter of the butt joint 221. After the liquid inlet pipe 51 enters into the butt joint 221, the sealing ring seals the gap between the outer wall of the liquid inlet pipe 51 and the inner wall of the butt joint 221, so that the cleaning liquid can only be discharged from the liquid inlet pipe 51 after passing through the liquid inlet hole and the overflow groove in sequence.

[0041] When installing the liquid storage bottle 2, align the liquid inlet pipe 51 with the docking pipe 221, then push the liquid inlet pipe 51 into the docking pipe 221, and make the liquid inlet pipe 51 push the tapered section 261 of the stop valve stem 26 away from the docking pipe, so that the docking pipe 221 is no longer isolated from the inner cavity of the liquid storage bottle 2; when the liquid storage bottle 2 is installed in place, the overflow groove 2611 connects the liquid inlet pipe 51 with the inner cavity of the liquid storage bottle 2.

[0042] When the liquid storage bottle 2 is removed, as the liquid inlet tube 51 is gradually pulled out of the docking tube 221, the stop valve stem 26 rebounds toward the docking tube 221 under the action of the third elastic member 27, and pushes the overflow section completely into the docking tube 221, and makes the conical section 261 block the docking tube 221, so that the docking tube 221 is isolated from the inner cavity of the liquid storage bottle 2.

[0043] In this embodiment, the third elastic member 27 is a spring sleeved outside the straight rod section 262 , and two ends of the third elastic member 27 abut against the conical section 261 and the limiting cover 25 respectively.

[0044] In this embodiment, if Fig.14 As shown, a filling port 28 is provided at one end of the liquid storage bottle 2 away from the pump head 5. When filling the cleaning liquid, the filling is performed through the filling port 28. The filling port 28 is equipped with a corresponding sealing cover. After the filling is completed, the filling port 28 can be covered.

[0045] In other embodiments, the filling port 28 may not be provided, and the cleaning liquid is filled into the liquid storage bottle 28 through a pipeline, connected to the docking pipe 221 through the pipeline, and the stop valve stem 26 is pushed to communicate with the inner cavity of the liquid storage bottle 2 to achieve filling.

[0046] In other embodiments, the liquid storage bottle 2 is a disposable item, and the entire liquid storage bottle 2 and the cleaning liquid are directly replaced together without filling, and thus the filling port 28 does not need to be provided.

[0047] Embodiment 2:

[0048] Based on the first embodiment, this embodiment provides a quick disassembly and assembly structure for the liquid storage bottle and the pump head.

[0049] In this embodiment, if Figures 1 to 9The soap dispenser shown can be automatically sealed when the liquid storage bottle is removed, and comprises a shell 1, a pump head 5, a fixing seat 3, a lifting mechanism 4 and a liquid storage bottle 2, wherein the liquid storage bottle 2 is mounted at one end inside the shell 1, the pump head 5 is mounted at the other end of the shell 1, the pump head 5 is mounted on the fixing seat 3, the liquid inlet pipe 51 of the pump head 5 is connected to the liquid storage bottle 2 and the liquid outlet pipe 52 of the pump head 5 passes through the shell 1; the lifting mechanism 4 comprises a pressing block 41, a connecting rod 42 and a clamping seat 43, the clamping seat 43 and the pressing block 41 are connected by the connecting rod 42; the clamping seat 43 is slidably mounted on the bottom of the fixing seat 3, the connecting rod 42 passes through the fixing seat 3, and the pressing block 41 and the top surface of the fixing seat 3 are provided with a first elastic member 421; the fixing seat 3 is provided with a second elastic member 33, and the second elastic member 33 is clamped on the side of the top surface of the clamping seat 43 away from the liquid storage bottle 2. When the soap dispenser is in normal use, the liquid storage bottle 2 pushes the second elastic member 33 to disengage from the clamping seat 43. After the clamping seat 43 loses the limit of the second elastic member 33, the first elastic member 421 pushes the pressing block 41 upward, thereby driving the clamping seat 43 to press against the liquid storage bottle 2; when the cleaning liquid needs to be replaced, the pressing block 41 is pressed, and the clamping seat 43 moves down and disengages from the liquid storage bottle 2, so that the liquid storage bottle 2 is no longer clamped, and the liquid storage bottle 2 can be directly pulled out of the pump head 5. After the liquid storage bottle 2 is pulled out, the second elastic member 33 automatically rebounds under the action of elastic force and is clamped on the clamping seat 43. The clamping seat 43 sinks below the top wall of the fixing seat 3 at this time and no longer blocks the liquid storage bottle 2. After the cleaning liquid in the liquid storage bottle 2 is replenished, the liquid storage bottle 2 is docked with the pump head 4, and the liquid storage bottle 2 pushes the second elastic member 33 away from the clamping seat 43, so that the clamping seat 43 moves upward under the action of the first elastic member 421 and clamps the liquid storage bottle 2, completing the fixation of the liquid storage bottle 2. When the utility model replenishes the cleaning liquid, it is only necessary to press the pressing block 41 to remove the liquid storage bottle 2. After the cleaning liquid is replenished, it is only necessary to align the liquid storage bottle 2 with the pump head 5 and push the second elastic member 33 away from the clamping seat 43. Then the first elastic member 421 drives the pressing block 41 and the clamping seat 43 to automatically rebound and lock the liquid storage bottle 2. The disassembly and installation are extremely simple and the use is extremely convenient.

[0050] Embodiment three:

[0051] In this embodiment, based on any of the above embodiments, the specific structure of the lifting mechanism provides an optional solution.

[0052] In this embodiment, if Figures 4 to 8 As shown, the middle of the top surface of the clamping seat 43 has an arc-shaped area 44, the second elastic member 33 is clamped on one side of the arc-shaped area 44, and a clamping protrusion 45 is provided on the other side of the arc-shaped area 44; a positioning cover 22 is provided on the bottleneck 21 of the liquid storage bottle 2.

[0053] In normal use, the positioning cover 22 is located in the arc-shaped area 44 and is pressed against the second elastic member 33, and the clamping protrusion 45 is located between the positioning cover 22 and the body of the liquid storage bottle 2 and is pressed against the neck 21. At this time, the positioning cover 22 of the liquid storage bottle 2 is located in the arc-shaped area 44, and the center of the positioning cover 22 is connected to the inside of the liquid storage bottle 2. After the positioning cover 22 pushes the second elastic member 33 to disengage from the clamping seat 43, the liquid outlet pipe 53 is also clamped into the neck 21, thereby communicating with the inner cavity of the liquid storage bottle 2.

[0054] When disassembling the liquid storage bottle 2, the pressing block 41 is pressed, and the clamping protrusion 45 moves toward the bottom of the fixing seat 3 until the clamping protrusion 45 sinks below the top surface of the fixing seat 3. At this time, the clamping protrusion 45 no longer clamps the neck 21 of the liquid storage bottle 2. The liquid storage bottle 5 can be removed by pulling the liquid storage bottle 2 toward the end away from the pump head 5. After the liquid storage bottle 2 is pulled out, the second elastic member 33 automatically rebounds and clamps on the clamping seat 43, so that the first elastic member 421 cannot rebound. Therefore, when installing the liquid storage bottle 2 again, the center of the positioning cover 22 is directly aligned with the liquid inlet pipe 51 and then pushed toward the pump head 5 to make the second elastic member 33 disengage from the clamping seat 43, and the first elastic member 421 automatically rebounds and drives the clamping seat 43 to clamp the neck 21.

[0055] In this embodiment, the pump head 5 includes a pressing rod 53, and a pressing plate 11 is hingedly installed at one end of the upper shell of the shell 1, and the pressing plate 11 is in contact with the pressing rod 53. When the cleaning liquid is needed, pressing the pressing plate 11 can synchronously push the pressing rod 53 to move, so that the liquid inlet pipe 51 and the liquid outlet pipe 52 are connected, and the cleaning liquid in the liquid storage bottle 2 can flow out from the liquid outlet pipe 52. The pump head mentioned in this application can refer to the pump head disclosed in the utility model patent with patent number ZL202320678895.9, and its structure and principle are not repeated here.

[0056] In this embodiment, if Figure 4 and Figure 8 As shown, a clamping wall 46 is provided on one side of the arc-shaped area 44 away from the clamping protrusion 45 , and the second elastic member 33 is clamped on the clamping wall 46 .

[0057] Embodiment 4:

[0058] This embodiment provides an optional solution for the specific structure of the fixing seat based on any of the above embodiments.

[0059] In this embodiment, if Figures 3 to 6 As shown, a mounting groove 31 is provided at the bottom of the fixing seat 3, and the clamping seat 43 can be slidably installed in the mounting groove 31. Through holes 35 are provided on both sides of the top wall of the fixing seat 3, and the connecting rod 42 passes through the through holes 35 to connect the clamping seat 43 and the pressing block 41 together. The first elastic member 421 is arranged between the pressing block 41 and the top wall of the fixing seat 3.

[0060] In this embodiment, the first elastic member 421 is a spring sleeved on the outside of the connecting rod 42 .

[0061] In this embodiment, if Figure 5 and Figure 6 As shown, a metal spring piece 37 is installed at the bottom of the fixing seat 3 , and the metal spring piece 37 is pressed against the second elastic member 33 .

[0062] Specifically, a mounting hole 34 is provided on one side of the fixing seat 3 away from the clamping block 43 , and the metal spring 37 and the pump head 5 are respectively mounted at the upper and lower ends of the mounting hole 34 .

[0063] In this embodiment, the second elastic member 33 is an L-shaped sheet, and the metal spring sheet 37 provides elasticity for the L-shaped sheet. After the liquid storage bottle 2 is pulled out from the pump head 5, the elasticity of the metal spring sheet 37 pushes the top end of the L-shaped sheet to be clamped on the clamping wall 46, thereby completing the limiting of the clamping seat 43.

[0064] In this embodiment, if Figures 3 to 6 and Fig. 9 As shown, a positioning foot 36 is provided at the bottom of the fixing seat 3, and a plurality of positioning ribs 13 are provided on both sides of the inner cavity of the lower shell 12 of the shell 1.
