Description

Technical Field

[0001] The utility model relates to the technical field of lotion pumps, in particular to an anti-blocking pump core with a ejector pin. Background Art

[0002] At present, washing products such as laundry detergent, shampoo and shower gel are all provided with a plastic bottle body, the bottle body is provided with a lotion pump, the lotion pump is provided with a straw and a pressing head, the straw is used to be inserted into the bottle body, and the pressing head is arranged on the upper side of the bottle body. When the pressing head is repeatedly pressed downward by hand, the pump core piston and the ball valve of the lotion pump cooperate with each other, and the straw can absorb the lotion in the bottle body, so that the lotion is sprayed out from the liquid spray nozzle of the pressing head.

[0003] For example, the public document with application number 202121042038.7 discloses an anti-blocking pump core with a ejector pin. The utility model can achieve that when encountering viscous emulsion or harder emulsion or paste, the ejector pin is pushed by the return of the suction pump and then the rubber filter ring is pushed back by the ejector pin to return it to its position, thereby solving the problem that the rubber filter ring that can disperse and extrude liquid and paste cannot return to its position due to the obstruction of viscous emulsion after being pushed up by negative pressure. However, when the viscous emulsion is transported by this pump core, some accumulated emulsion may produce slight caking in low temperature weather. Although the emulsion is soft after agglomeration, it will get stuck at the ball head valve port of the pump body, causing blockage of the entire pump core, making it difficult to discharge the emulsion stably.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-blocking pump core with a ejector pin is proposed. Utility Model Content

[0005] The utility model aims to provide an anti-blocking pump core with an ejector pin to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-blocking pump core with an ejector, comprising a liquid storage cavity, a liquid inlet is fixedly arranged at the bottom end of the liquid storage cavity, a horizontal plate is fixedly installed on the upper end of the inner surface of the liquid inlet, a fixing rod is fixedly arranged on the middle part above the surface of the horizontal plate, a blade wheel is rotatably arranged on the top end of the fixing rod, a sliding block is fixedly installed on the right side of the surface of the blade wheel, an ejector tube is slidably arranged through the middle part above the surface of the liquid storage cavity, and a spiral groove is opened on the lower part of the inner surface of the ejector tube.

[0007] Preferably, the transverse plate only occupies the middle part of the top end of the liquid inlet and its two sides do not block the liquid inlet, and the middle blades of the impeller are arranged as inclined surfaces.

[0008] Preferably, the blade wheel is extended by a fixing rod and located inside the ejector tube. When the ejector tube is moved upward and reset, the blade wheel can be located exactly at the inner bottom end of the ejector tube. The slider is slidably arranged inside the spiral groove.

[0011] Preferably, a piston is fixedly mounted below the surface of the ejector tube located inside the liquid storage cavity, and the piston is slidably fitted to the inner surface of the liquid storage cavity.

[0012] Preferably, a conical ring plate is fixedly installed above the inner surface of the ejector tube, and a sphere is placed on the surface of the conical ring plate. The liquid inlet is also arranged in an inverted cone shape, and a sphere is also placed inside the liquid inlet.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a blade wheel, a slider, an ejector tube and a spiral groove. When the ejector tube is pressed down or reset and moved up, the spiral groove uses its own spiral texture to push the slider to rotate and move, thereby driving the blade wheel to rotate inside the ejector tube to stir the emulsion, which can effectively prevent the emulsion from being accumulated and blocked during transportation, and greatly improve the stability of the emulsion extrusion transportation;

[0015] 2. The utility model arranges a sealing plate and a tension spring. The tension spring provides the pulling force for resetting the ejector tube through the sealing plate. At the same time, the sealing plate arranges the upper part of the liquid storage chamber as an independent space. Cooperating with the top seal of the liquid storage chamber, the tension spring is placed in an independently sealed internal cavity, so as to avoid contact between the spring and the material body when the emulsion enters the liquid storage chamber, thereby effectively preventing the spring from rusting and contaminating the emulsion material body.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, an anti-blocking pump core with an ejector pin comprises a liquid storage chamber 1, a liquid inlet 2 is fixedly provided at the bottom end of the liquid storage chamber 1, a horizontal plate 3 is fixedly installed on the upper end of the inner surface of the liquid inlet 2, a fixing rod 4 is fixedly provided on the middle part above the surface of the horizontal plate 3, a blade wheel 5 is rotatably provided on the top end of the fixing rod 4, a slider 6 is fixedly installed on the right side of the surface of the blade wheel 5, an ejector tube 7 is slidably provided through the middle part above the surface of the liquid storage chamber 1, a spiral groove 8 is opened at the lower part of the inner surface of the ejector tube 7, the blade wheel 5 is extended by the fixing rod 4 and is located inside the ejector tube 7, and when the ejector tube 7 is moved up and reset, the blade wheel 5 can be just located at the inner bottom end of the ejector tube 7, and the slider 6 is slidably provided inside the spiral groove 8.

[0022] Through the above technical solution, when the ejector tube 7 moves up and down, the spiral groove 8 uses its own upward oblique spiral texture to push the slider 6 to rotate, thereby driving the blade wheel 5 to rotate, and the emulsion transported or temporarily stored inside the ejector tube 7 can be stirred, effectively preventing the ejector tube 7 from being blocked by the emulsion.

[0023] Furthermore, the transverse plate 3 only occupies the middle part of the top end of the liquid inlet 2 and its two sides do not block the liquid inlet 2, and the middle blades of the impeller 5 are set as inclined surfaces.

[0024] Through the above technical solution, the horizontal plate 3 only occupies a small part of the liquid inlet 2 and is flush with the top of the liquid inlet 2, avoiding obstruction of the liquid inlet 2 from conveying the emulsion to the liquid storage chamber 1, and can limit the ball 13 inside the liquid inlet 2.

[0025] Furthermore, a sealing plate 9 is slidably disposed above the inner surface of the liquid storage chamber 1 , and the sealing plate 9 is fixedly connected to the ejector tube 7 located above the inside of the liquid storage chamber 1 .

[0026] Through the above technical solution, the sealing plate 9 isolates a closed space above the inside of the liquid storage chamber 1 to prevent the spring from contacting the material body when the emulsion enters the liquid storage chamber 1.

[0027] Furthermore, a tension spring 10 is fixedly disposed above the surface of the sealing plate 9 , and the top end of the tension spring 10 is fixedly connected to the top end of the inner surface of the liquid storage chamber 1 .

[0028] Through the above technical solution, the tension spring 10 can use the sealing plate 9 to give the ejector tube 7 the ability to automatically reset and rebound.

[0029] Furthermore, a piston 11 is fixedly mounted below the surface of the ejector tube 7 inside the liquid storage chamber 1 , and the piston 11 is slidably fitted to the inner surface of the liquid storage chamber 1 .

[0030] Through the above technical solution, the piston 11 moves up and down following the ejector tube 7, so as to suck the emulsion.

[0031] Furthermore, a conical ring plate 12 is fixedly installed above the inner surface of the ejector tube 7, and a sphere 13 is placed on the surface of the conical ring plate 12. The liquid inlet 2 is also configured as an inverted cone, and a sphere 13 is also placed inside the liquid inlet 2.

[0032] Through the above technical solution, the conical ring plate 12 and the ball 13 inside the conical liquid inlet 2 play the role of a one-way valve. When the piston 11 moves downward, the emulsion can only push the ball 13 inside the ejector tube 7 to discharge. When the piston 11 moves upward, the ball 13 inside the liquid inlet 2 can be sucked up slightly by air pressure, opening the liquid inlet 2 so that the emulsion is sucked into the liquid storage chamber 1 through the liquid inlet 2 to replenish it.

[0033] Working Principle: When using the anti-blocking pump element with ejector pin, first:

[0034] Embodiment 1: Press the ejector tube 7 downward, the ejector tube 7 will drive the sealing plate 9 to move downward, and pull the tension spring 10 to extend. At this time, the piston 11 will follow the ejector tube 7 to move downward and push. The pressure at this time is transmitted to the emulsion at the bottom of the liquid storage chamber 1, but the ball 13 inside the liquid inlet 2 is subjected to the pushing pressure from above, and can only move downward and fit closely to the liquid inlet 2 for blocking. The pressure direction of the emulsion can only move toward the inside of the ejector tube 7, thereby entering the ejector tube 7, pushing the ball 13 inside the ejector tube 7 upward to move up for discharge, and releasing the ejector tube 7. Under the action of the tension spring 10, the ejector tube 7 and the piston 11 will be pulled upward and reset through the sealing plate 9. When moving upward, the piston 11 will use the suction force to pull the ball 13 inside the liquid inlet 2 slightly upward, open the liquid inlet 2, and suck the emulsion in the bottle body into the bottom of the liquid storage chamber 1, so as to prepare to move downward and squeeze out the liquid.

[0035] Embodiment 2: When the ejector tube 7 moves up and down, the spiral groove 8 also moves up and down. The spiral groove 8 uses its own inclined thread pattern to push the slider 6 to rotate, thereby driving the blade wheel 5 to rotate. When the blade wheel 5 rotates inside the ejector tube 7, it stirs the emulsion in the ejector tube 7 to prevent blockage during the emulsion delivery process. This is the working principle of the anti-blocking pump core with an ejector.
