Description

Technical Field

[0001] The invention belongs to the technical field of compression pumps, in particular to a quantitative manual pressure-boosting compression pump. Background Art

[0002] A press pump is a common liquid delivery device that squeezes liquid out of a container by manual pressure. It is widely used in various occasions, such as packaging of liquid products such as cosmetics, medicines, detergents, lubricants, etc.

[0003] Existing press pumps are usually composed of components such as a pump body, a piston, a spring and a valve. When the pump body is pressed, the piston moves downward, squeezing the liquid in the pump body to make it flow out through the valve. When the pump body is released, the spring pushes the piston back to its original position. During long-term use and observation, it is found that during actual use, the existing press pumps will cause the amount of liquid squeezed out to be more or less due to the different lengths of the pressing stroke, making it difficult to control the amount of liquid squeezed out.

When it is necessary to extrude the liquid quantitatively, the lock buckle 17 can be opened to both sides and then aligned with a limiting groove 16 on the liquid collection tube 13. Then, the lock buckle 17 is stuck in the limiting groove 16 under the rebound action of the torsion spring. When the pressure head 14 is pressed to drive the liquid collection tube 13 to move into the pump body 11, the lock buckle 17 and the baffle 18 will be driven to move toward the top of the threaded lock cover 1. At this time, the baffle 18 will be stuck on the top of the lock buckle 17, thereby limiting the distance that the liquid collection tube 13 descends, thereby controlling the extrusion amount of the liquid. Through the above structure, the limiting groove 16 is set to cooperate with the lock buckle 17 and the baffle 18, so as to limit the extrusion amount of the liquid, and achieve the effect of quantitative liquid discharge, so as to reduce the situation where the liquid extrusion amount is more or less difficult to control.

[0028] like Figure 3 As shown, the side wall of the lock buckle 17 is provided with a fixing groove 2; the side wall of the fixing groove 2 is provided with a fixing hole 21; a fixing belt 22 is fixedly connected to a side wall of the fixing groove 2 away from the fixing hole 21; the fixing belt 22 is made of flexible material; a plug rod 23 is fixedly connected to the side wall of the fixing belt 22; the plug rod 23 faces the side of the fixing groove 2; when working, after the lock buckle 17 is stuck on the limit groove 16, the fixing belt 22 is pulled to drive the plug rod 23 to approach one side of the fixing groove 2, and then the plug rod 23 is inserted into the fixing groove 2, at this time, the opening of the lock buckle 17 can be fixed, and when the lock buckle 17 needs to be opened, the plug rod 23 is taken out of the fixing groove 2 to release the fixation of the lock buckle 17. Through the above structure, the fixing belt 22, the plug rod 23 and the fixing groove 2 are set, and the opening position of the lock buckle 17 can be fixed to improve the stability of the position of the lock buckle 17 and reduce the situation where the lock buckle 17 is opened and falls off during use.

[0029] like Figure 3 and Figure 4As shown, a pair of limiting holes 3 are opened on the inner side wall of the lock buckle 17; the pair of limiting holes 3 are symmetrical in structure; a pair of limiting rods 31 are fixedly connected to the side wall of the limiting groove 16; the limiting rods 31 are arranged corresponding to the limiting holes 3; during operation, when the lock buckle 17 is stuck in the limiting groove 16, the limiting holes 3 on both sides of the lock buckle 17 are aligned with the limiting rods 31 on the limiting groove 16, and after the lock buckle 17 is stuck on the limiting groove 16, the limiting rods 31 will be inserted into the limiting holes 3 to fix the position of the lock buckle 17 on the limiting groove 16. Through the above structure, the limiting rods 31 and the limiting holes 3 are set, and the lock buckle 17 can be fixed on the limiting groove 16 to reduce the self-rotation of the lock buckle 17 on the limiting groove 16, which leads to greater wear.

[0030] like Figure 3 As shown, the end of the liquid outlet pipe 15 is fixedly connected with a sleeve 4; the end of the sleeve 4 is hinged with a pair of sealing plates 41 through a torsion spring; the sealing plate 41 is a semicircular structure; during operation, when liquid is squeezed out of the liquid outlet pipe 15, the sealing plate 41 will open under the squeezing action of the liquid, and after the liquid is squeezed out, the sealing plate 41 will reset under the elastic force of the torsion spring, thereby covering the outlet of the liquid outlet pipe 15. Through the above structure, the sleeve 4 and the sealing plate 41 are arranged, so that the liquid can be squeezed out normally and the port of the liquid outlet pipe 15 can be covered at the same time, so as to reduce the liquid remaining in the liquid outlet pipe 15, which will harden and block the liquid outlet pipe 15 due to contact with the outside air.

[0031] like Figure 1 and Figure 5 As shown, a guide plate 5 is fixedly connected to the bottom of the conduit 12; a plurality of shunt pipes 51 are connected to the side wall of the guide plate 5; the shunt pipes 51 are made of flexible material; during operation, when the conduit 12 is inserted into the container, the guide plate 5 and the shunt pipes 51 are driven into the container, at which time the shunt pipes 51 are in contact with the bottom of the container, and when the liquid in the container enters the conduit 12, it enters the plurality of shunt pipes 51 respectively, and then converges into the conduit 12. Through the above structure, the guide plate 5 and the shunt pipes 51 are arranged, which can reduce the situation in which the liquid in the container cannot be sucked into the conduit 12 and causes waste due to a large distance difference between the liquid and the conduit 12 when the liquid touches the bottom.

[0032] like Figure 5 As shown, the side wall of the guide plate 5 is fixedly connected with a support rod 6; the end of the support rod 6 is fixedly connected to the side wall of the shunt tube 51; the support rod 6 is made of elastic material; during operation, when the shunt tube 51 and the support rod 6 are inserted into the container along with the conduit 12, the support rod 6 can be squeezed to gather inward, and after being inserted into the container, the support rod 6 rebounds to open the shunt tube 51, so that the shunt tube 51 contacts the bottom edge of the container. Through the above structure, the support rod 6 is arranged to open the shunt tube 51 to increase the contact range between the shunt tube 51 and the bottom of the container, so as to reduce the possibility of the shunt tube 51 being rolled up and entangled.

[0033] like Figure 2 As shown, the top of the pressure head 14 is fixedly connected with an anti-skid pad 7; the top of the anti-skid pad 7 is provided with anti-skid grooves; when working, when the pressure head 14 is pressed, it will contact the anti-skid pad 7 on its top. Through the above structure, the anti-skid pad 7 is provided to connect the pressure head 14, which can increase the friction when the pressure head 14 is pressed, so as to reduce slipping and improve stability during use.

[0034] like Figure 3 As shown, an anti-vibration pad 8 is fixedly connected to the bottom of the baffle 18; the anti-vibration pad 8 is of the same size as the baffle 18; during operation, when the pressing head 14 drives the baffle 18 to move toward the top of the threaded lock cover 1, the anti-vibration pad 8 at the bottom of the baffle 18 will contact the top of the threaded lock cover 1. Through the above structure, the anti-vibration pad 8 is arranged to connect the baffle 18, which can reduce the impact force between the baffle 18 and the top of the threaded lock cover 1, thereby reducing the loose connection and playing a buffering and vibration reduction role.

[0035] Working principle: Connect the threaded lock cap 1 with the container, then press the pressure head 14 to drive the piston in the pump body 11, suck the liquid in the container from the conduit 12, then enter the cavity in the pressure head 14 through the liquid collection tube 13, and finally discharge it from the liquid outlet tube 15. When it is necessary to extrude the liquid quantitatively, the lock buckle 17 can be opened to both sides, and then aligned with a limit groove 16 on the liquid collection tube 13, and then the lock buckle 17 is stuck on the limit groove 16 under the rebound action of the torsion spring. When the pressure head 14 is pressed to drive the liquid collection tube 13 to move into the pump body 11, the lock buckle 17 will be driven to align with the limit groove 16. The baffle 18 moves toward the top of the threaded lock cover 1, and at this time the baffle 18 will be stuck on the top of the lock buckle 17, thereby limiting the distance that the liquid extraction tube 13 descends, thereby controlling the amount of liquid extruded. After the lock buckle 17 is stuck on the limiting groove 16, the fixing belt 22 is pulled to drive the insertion rod 23 to approach one side of the fixing groove 2, and then the insertion rod 23 is inserted into the fixing groove 2. At this time, the opening of the lock buckle 17 can be fixed. When the lock buckle 17 needs to be opened, the insertion rod 23 is taken out from the fixing groove 2 to release the fixation of the lock buckle 17. When the lock buckle 17 is stuck in the limiting groove 16, the two sides of the lock buckle 17 are The limiting hole 3 is aligned with the limiting rod 31 on the limiting groove 16. After the lock buckle 17 is stuck on the limiting groove 16, the limiting rod 31 will be inserted into the limiting hole 3 to fix the position of the lock buckle 17 on the limiting groove 16. When the liquid is squeezed out from the liquid outlet pipe 15, the sealing plate 41 will open under the squeezing effect of the liquid. After the liquid is squeezed out, the sealing plate 41 will reset under the elastic force of the torsion spring, thereby covering the outlet of the liquid outlet pipe 15. When the catheter 12 is inserted into the container, it will drive the guide plate 5 and the shunt pipe 51 into the container. At this time, the shunt pipe 51 will contact with the bottom of the container. When the liquid in the container enters the conduit 12, it will enter the multiple shunt tubes 51 respectively, and then gather into the conduit 12. When the shunt tubes 51 and the support rod 6 are inserted into the container along with the conduit 12, they can be gathered inward by squeezing the support rod 6. After being inserted into the container, the support rod 6 rebounds and opens the shunt tube 51, so that the shunt tube 51 contacts the bottom edge of the container, and contacts the anti-slip pad 7 on the top when the pressure head 14 is pressed. When the pressure head 14 is pressed to drive the baffle 18 to move toward the top of the threaded lock cover 1, the anti-vibration pad 8 at the bottom of the baffle 18 contacts the top of the threaded lock cover 1.
