[0002] In daily life, people often use shampoo or detergent. Their pump heads are composed of a push-type pump head, a pump tube, a bottle mouth joint and a pressure pump. One end of the pump tube is connected to the pressure pump, and the other end is connected to the liquid outlet pipe of the push-type pump head. The pressure pump works by applying downward pressure to the push-type pump head, sucking the liquid in the bottle into the pump tube and flowing it out from the liquid outlet pipe. The pump head with this structure has a fixed liquid output and is more convenient to use.

[0003] In the current technologies for controlling the amount of liquid discharged, most of them involve modification of the pump tube, such as adding limit blocks, limit buckles, threads, stops, etc. However, these designs first require modification of the original pump tube to meet the rigid conditions for matching with additional components, such as thickness, length, thickness, strength, etc., which increases the process and increases the cost. Secondly, such designs will change the original product appearance design, which will affect the inherent appearance design of the brand to a certain extent, and thus affect the choice of consumers. Therefore, the utility model provides a push-type pump head that can control the amount of liquid discharged. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example

[0022] like Figure 1-2 As shown, a push-type pump head capable of controlling the amount of liquid discharged comprises a bottle body 1, a bottle mouth joint 2, a liquid discharge pump head 3 and a pump tube 4, the outer circumferential surface of the bottle body 1 is threadedly connected with the bottle mouth joint 2, the upper end of the bottle mouth joint 2 is embedded with the liquid discharge pump head 3, the inner wall of the liquid discharge pump head 3 is provided with a thread groove 1 31, a pump tube 4 is arranged in the bottle mouth joint 2, the pump tube 4 extends into the bottle body 1, a catheter 5 is slidably connected in the pump tube 4, a thread groove 2 51 is arranged on the outer circumferential surface of the upper end of the catheter 5, the upper end of the catheter 5 is threadedly connected with the liquid discharge pump head 3 through the thread groove 2 51 and the thread groove 1 31, a piston 6 is fixedly connected to the outer circumferential surface of the catheter 5, the outer circumferential surface of the piston 6 is in close contact with the inner wall of the pump tube 4, a spring 1 7 is fixedly connected to the lower end of the catheter 5, a ball valve 8 is fixedly connected to the lower end of the spring 1 7, a valve port 41 is arranged on the inner wall of the pump tube 4, and the valve port 41 matches the ball valve 8.

[0023] When in use, the area where the outer circumferential surface of the spring 17 in the pump tube 4 is located is a temporary liquid storage bin. When a person presses the liquid outlet pump head 3, the liquid outlet pump head 3 drives the conduit 5 and the piston 6 to squeeze the temporary liquid storage bin. Subsequently, the liquid in the temporary liquid storage bin will flow out of the liquid outlet pump head 3 through the conduit 5. After the liquid in the temporary liquid storage bin is discharged, the piston 6 rises with the elastic force of the spring 17. Under the action of the air pressure difference, the ball valve 8 will move upward, thereby opening the valve port 41. As the liquid enters the temporary liquid storage bin, the air pressure difference is compensated, and the ball valve 8 will reset and block the valve port 41. This is a liquid discharge process.

[0024] The personnel can rotate the liquid discharge pump head 3 clockwise or counterclockwise to make the internal thread groove 1 31 combined with the upper thread groove 2 51 of the catheter 5 drive the catheter 5 to move up and down. After the catheter 5 moves up and down, its spring 1 7 will also stretch or contract to different degrees. When the spring 1 7 stretches or contracts to different degrees, when the user presses the liquid discharge pump head 3, the actual contraction and rebound length of the spring 1 7 will also be affected, thereby realizing the increase or decrease of the liquid discharge amount.

[0025] Assuming that the length of the second thread groove 51 is L1, the initial length of the spring 1 7 is L0, and the length of the spring 1 7 after compression is L2, it should be ensured that L1>ΔL=L0-L2, so that the function of locking the pressing pump head can be achieved, and the full flow control from the maximum amount to the minimum amount can be achieved, and at the same time, it is ensured that the liquid discharge pump head 3 will not be disengaged from the catheter 5;

[0026] The lower part of the conduit 5 is in an inverted basin shape, which improves the stability of the connection with the spring 7.

[0027] like Figure 1 As shown, a vertical guide groove 42 is formed on the inner wall of the pump tube 4 , and a limiting strip 52 is fixedly connected to the outer circumferential surface of the conduit 5 , and the limiting strip 52 corresponds to the vertical guide groove 42 .

[0028] During use, when the liquid discharge pump head 3 is rotated, due to the limitation of the limiting block 52 and the vertical guide groove 42, the conduit 5 does not rotate relatively when it moves up and down with the rotation of the liquid discharge pump head 3.

[0029] like Figure 2 As shown, the lower end of the liquid discharge pump head 3 is fixedly connected with a limit buckle 32.

[0030] When in use, the limit buckle 32 is used to prevent the liquid discharge pump head 3 from being pressed by the elastic force of the spring 7 and falling off.

[0031] like Figure 2 As shown, a pressure ring 43 is fixedly connected to the outer circumferential surface of the pump tube 4 , a sealing ring 44 is provided on one side of the pressure ring 43 , and the sealing ring 44 is clamped between the pressure ring 43 and the bottle body 1 .

[0032] When in use, after the bottle mouth connector 2 is tightened, the pressure ring 43 will squeeze the sealing ring 44, thereby improving the sealing effect.

[0033] like Figure 1 As shown, the lower end of the liquid discharge pump head 3 is fixedly connected with a spring 9 , and the lower end of the spring 9 is fixed to the pump tube 4 .

[0034] When in use, the spring 2 9 can assist the liquid discharge pump head 3 to rebound.

[0035] In summary, the specific working process of this scheme is as follows: in the pump tube 4, the area where the outer circumferential surface of the spring 1 7 is located is a temporary liquid storage bin. When a person presses the liquid outlet pump head 3, the liquid outlet pump head 3 drives the conduit 5 and the piston 6 to squeeze the temporary liquid storage bin. Subsequently, the liquid in the temporary liquid storage bin will flow out of the liquid outlet pump head 3 through the conduit 5. After the liquid in the temporary liquid storage bin is discharged, when the piston 6 rises with the elastic force of the spring 1 7, the ball valve 8 will move upward under the action of the air pressure difference, thereby opening the valve port 41. As the liquid enters the temporary liquid storage bin, the air pressure difference is compensated, and the ball valve 8 will reset and block the valve port 41. This is a liquid discharge process.

[0036] Among them, when the personnel rotates the liquid discharge pump head 3 clockwise or counterclockwise, the internal thread groove 31 is combined with the upper thread groove 51 of the catheter 5 to drive the catheter 5 to move up and down. After the catheter 5 moves up and down, its spring 17 will also stretch or contract to different degrees. When the spring 17 stretches or contracts to different degrees, when the user presses the liquid discharge pump head 3, the actual contraction and rebound length of the spring 17 will also be affected, thereby achieving an increase or decrease in the amount of liquid discharged.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
