Description

Technical Field

[0001] The utility model relates to the technical field of press pumps, in particular to a full-plastic press pump body. Background Art

[0002] The application of press pumps in daily chemical products has been very extensive, bringing convenience to life. In existing press pumps, metal springs are generally used as the rebound device of the press head, and glass beads are used as one-way seals. Therefore, existing press pumps usually include parts such as plastic, metal and glass. When recycling, the press pumps need to be disassembled and then sorted for recycling. This is inconvenient and also increases the labor cost of recycling. In addition, during the assembly process of existing press pumps, after the bottle lock cap is plugged into the upper end of the pump housing, a locking cap is usually plugged into the upper end of the pump body to fix the bottle lock cap on the pump body to prevent it from loosening. The structure is complex and the assembly process is cumbersome. Therefore, a fully plastic press pump body is proposed to solve the above-mentioned problems. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a fully plastic press pump body in view of the deficiencies in the above-mentioned prior art.

[0011] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. The all-plastic press pump body, whose components are all made of plastic materials, does not need to be disassembled and separated during recycling, reducing the difficulty and cost of recycling. The plastic spring is used to block the wedge-shaped slider, so that the wedge-shaped slider limits the fixing ring and the pump casing, thereby locking the pump casing and the lock bottle cap to prevent the lock bottle cap from loosening. The structure is simple and easier to assemble.

[0013] 2. The all-plastic push pump body, by clamping the sealing gasket in the sealing groove of the sealing plate, uses the sealing gasket and the sealing plate to seal the pump housing and the lock bottle cap to prevent liquid leakage during use and improve the sealing performance. The anti-slip grooves increase the friction between the user's fingers and the push head to prevent the hand from slipping during use. The limit rod blocks the push head to prevent accidental contact with the push head when not in use and cause liquid leakage, making it easy to transport and carry. BRIEF DESCRIPTION OF THE DRAWINGS

The piston is located in the suction channel. By pressing the pressing head 1, the pump rod 3 and the piston are driven to move along the suction channel. At the same time, the pump rod 3 compresses the plastic spring 4. When the plastic spring 4 drives the pump rod 3 to rebound, a negative pressure is generated in the pump chamber 8 when the piston moves. At the same time, the one-way valve on the liquid inlet pipe 7 is opened, and the liquid enters the pump chamber 8 from the liquid inlet pipe 7. At the same time, the liquid is compressed into the channel of the pump rod 3 by the movement of the piston and discharged from the outlet of the pressing head 1, thereby completing the operation. The clamping mechanism 6 includes: a locking slide hole 61 and a fixing ring 62. The locking slide hole 61 is provided above the outer wall of the lock bottle cap 5, and the locking slide hole 61 is set in an "L" shape. The fixing ring 62 is fixedly sleeved on the outer wall of the pump housing 2. The outer wall of the fixing ring 62 is fixedly connected with a wedge-shaped slider 63, and the wedge-shaped slider 63 is slidably connected to the locking slide hole 61. The top of the inner wall of the locking slide hole 61 is fixedly connected with a plastic spring 64, and the plastic spring 64 abuts against the wedge-shaped slider 63. There are two groups of clamping mechanisms 6, and they are equidistantly spaced circumferentially. The setting is that the button head 1, pump housing 2, pump rod 3, plastic spring 4, bottle lock cap 5, fixing ring 62, wedge-shaped slider 63, plastic spring 64, and drainage tube 7 are all made of PP material, and its component parts are all made of plastic material. There is no need to disassemble and separate them during recycling, which reduces the difficulty and cost of recycling. The plastic spring 64 is used to block the wedge-shaped slider 63, so that the wedge-shaped slider 63 limits the fixing ring 62 and the pump housing 2, thereby locking the pump housing 2 and the bottle lock cap 5 to prevent the bottle lock cap 5 from loosening. The structure is simple and easier to assemble.

[0025] Working principle: By pressing the button 1, the pump rod 3 and the piston move along the suction channel, and at the same time, the pump rod 3 compresses the plastic spring 4. When the plastic spring 4 drives the pump rod 3 to rebound, a negative pressure is generated in the pump chamber 8 when the piston moves. At the same time, the one-way valve on the liquid inlet pipe 7 opens, and the liquid enters the pump chamber 8 from the liquid inlet pipe 7. At the same time, the liquid is compressed into the channel of the pump rod 3 through the movement of the piston and discharged from the outlet of the button 1, thereby completing the liquid discharge. By sliding the wedge-shaped slider 63 along the locking slide hole 61, the plastic spring 64 is used to lock the wedge-shaped slider. 63 is blocked, so that the wedge-shaped slider 63 limits the fixing ring 62 and the pump housing 2, thereby locking the pump housing 2 and the lock bottle cover 5 to prevent the lock bottle cover 5 from loosening. Conversely, the plastic spring piece 64 is pulled outward, and the pump housing 2 is rotated at the same time to drive the fixing ring 62 and the wedge-shaped slider 63 to move, so that the wedge-shaped slider 63 slides along the bottom of the inner wall of the locking slide hole 61 to a specified position, and then the wedge-shaped slider 63 is pulled upward to disengage it from the locking slide hole 61, thereby separating the pump housing 2, the fixing ring 62 and the lock bottle cover 5, and they can be disassembled.

[0026] See also Figure 1-5 On the basis of the above embodiment, in another embodiment of the present invention, the inner wall of the bottle lock cover 5 is fixedly connected with a sealing plate 9, the bottom of the fixing ring 62 is fixedly connected with a sealing gasket 10, the top of the sealing plate 9 is provided with a sealing groove, and the sealing gasket 10 is clamped in the sealing groove. By clamping the sealing gasket 10 in the sealing groove of the sealing plate 9, the sealing gasket 10 and the sealing plate 9 are used to seal between the pump housing 2 and the bottle lock cover 5, thereby preventing liquid leakage during use and improving the sealing performance; the top of the pressing head 1 is provided with an anti-slip groove 11, and the number of the anti-slip grooves 11 is several. And they are arranged at equal intervals, and the anti-slip grooves 11 are arranged to increase the friction between the user's fingers and the button 1 to prevent the hand from slipping during use; the top of the fixed ring 62 is connected to the limit rod 12, and the top of the limit rod 12 is close to the bottom of the button 1, and the top of the fixed ring 62 is provided with a slot 13, and the limit rod 12 is inserted into the slot 13. The sealing plate 9, the sealing gasket 10, and the limit rod 12 are all made of PP material. The button 1 is blocked by the limit rod 12, which can prevent the button 1 from accidentally touching and causing liquid leakage when not in use, and is convenient for transportation and carrying.

[0027] Working principle: By clamping the sealing gasket 10 in the sealing groove of the sealing plate 9, the sealing gasket 10 and the sealing plate 9 are used to seal the pump housing 2 and the bottle lock cover 5 to prevent liquid leakage during use.
