INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to emulsion pumps', and more particularly to an elastomer-free emulsion pump and a one-way valve employed therein. [Prior Art] In the existing lotion pump, the following problems are ubiquitous. First of all, the existing lotion pumps are equipped with metal springs, which makes the recycling a lot of inconvenience. When the lotion pump is to be recycled, the head must be removed to sort the metal springs. Due to the cumbersome operation, the lotion pump is rarely recycled, which creates obstacles to environmental protection and waste recycling. Secondly, the upper check valve of the existing lotion pump mainly has two structures. One is a one-way valve composed of a piston, a piston head and a connecting conduit. The other is a one-way valve consisting of a piston and a bead. In the former case, the accuracy of the three parts of the piston, the piston head and the cylinder is high. If the accuracy is not up to the requirement, problems such as high air pressure, poor hand feeling or leakage are likely to occur. In the latter case, 'the leak cannot be prevented when the head is open. Moreover, when applied to a high-viscosity occasion, the beads tend to adhere to the inner wall without falling after the upward movement, thereby causing the pump to be inoperable. Further, in the case of the spray pump, in order to have a good spray effect, it is necessary to have a large internal pressure in the entire process from the start of the spray to the stop of the spray. The internal pressure is higher as the spray effect is higher. In the existing spray pump, when an upper check valve consisting of a piston, a piston head and a connecting pipe is used, it is inside the six small springs 4 (four) hours on the piston; two directions: cannot be opened. When the internal money reaches a certain value: gram and the force of the small spring moves to cause the upper bitter to overcome the spray. However, this spray is opened, so that a high defect can be obtained. In order to overcome the above drawbacks, the main object of the present invention is to provide a springless lotion pump which is advantageous for environmental protection. Another object of the invention is to provide a one-way valve for a fluid-filled container that is simple in construction, automatic, and that provides a lotion pump, spray pump, and closure member using the early-direction valve. To this end, the present invention provides a lotion pump comprising: a press head, a head-connecting connecting pipe, a check valve is arranged on the connecting pipe or the pressure head, and a dental sleeve is provided for connecting a container The connection structure of the mouth; a cylinder, the upper end of the cylinder is connected to the mouthpiece, the lower end of the cylinder is provided with a Y check valve; a piston connected or integrally formed with the connecting pipe, the piston reciprocates in the cylinder; characterized in that the emulsion The pump does not have a magazine, and the upper soap valve includes an elastic tube and a valve seat. The valve seat is disposed on the connecting tube or the pressing head, and has a closed top end and an opening provided on the side surface, and the elastic tube is elastic. Covering the side of the valve seat and closing at least one opening 〇 Preferably, the emulsion pump is attached to the mouth of a container, and the container is fixed to a fixture. 1324087 Preferably, at least one protrusion is provided on the valve seat of the upper check valve. Preferably, the head is shaped to facilitate both pressing and pulling. The invention also provides a spray pump, comprising: a pressure head; a nozzle disposed on the pressure head; a piston rod connected to the pressure head, wherein the piston rod or the pressure head is provided with an upper one-way valve; , which is provided with a connection structure for connecting a mouth of a container; a cylinder, the upper end of the cylinder is connected to the mouthpiece,

Other objects, features, and advantages of the present invention will be made apparent DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, wherein like reference numerals refer to the Fig. 1 to Fig. 6 show a springless emulsion pump 1 according to a first embodiment of the present invention. The non-elastic emulsion pump 丨 mainly includes: indenter 2, braces 3, connecting guide 4, piston 5, check valve on cylinder 7, lower check valve 9 straw 9 and gasket ίο β ” The indenter 2 is pressed down and in the state of the lock head. The so-called "lock-like shape" is in the state in which the indenter 2 is locked, and it is not possible to extract the emulsion, and in this case, it is easy to transport and store. The "locking head" is achieved by the engagement of the external thread of the indenter 2, the external thread of the tooth #3. Fig. 2 shows the state in which the indenter is separated from the "lock" and pulled up. As shown in Fig. 1, 9 π- is not, the indenter 2 is connected to one end of the connecting duct 4. The other end of the connecting duct 4 is connected to the piston 5. The piston 5 reciprocates within the cylinder 6. Re-social. As shown in Fig. 3, the mouthpiece 3 is attached to the upper end of the cylinder 6, and has a connection structure 3a for connecting the mouth of the hexagon. The connection structure may take the form of a thread # λ # / a rib/groove, and other structures may be employed. The lower check valve 8 is provided at the lower end of the cylinder 6. The lower check valve 8 includes a bead 81 and a valve seat 61, and the reading frame 61 is integrally formed on the cylinder 6. In addition, the suction pipe 9 is transported to the lower end of the cylinder 6. A further 塾g can be placed in the mouthpiece 3 to form a good seal with the mouth of the barn. Gu Mingsi, lp It, the maximal/inventive of this lotion-free milk Hi with existing springs. Another break is that 'it does not have a check valve 7 for the piston 5 to be reset, and the springless lotion pump 1 is also used. The novel fluid is applied to the lotion pump, and can also be widely used. It is applied to a device cover member or the like, such as a spray-free or packaged springless emulsion spring to be described below. Therefore, there is no bullet in the live 0. Up and down in the cylinder 6 The movement of the ten-handed person by hand is performed by pulling or pressing the head 2 downward. For ease of operation, it is preferable to shape the indenter 2 to facilitate both pressing and pulling. As shown in Figs. 5A to 5D, the indenter 2 can be made into a shape suitable for fitting with a hand, for example, the indenter 2 can have a middle portion 2b and two side flanges 2a located on both sides of the center. As shown in Fig. 6, the operator can use the thumb buckle to fit the middle portion 2b, and the forefinger and the middle finger respectively engage the two side edges 2a so that the pull-up and push-down operations can be easily performed. Further, as shown in Fig. 6, in order to facilitate pulling up the ram 2, it is preferable to fix the yoke A to a fixture such as a wall surface or a table top. There are various ways of fixing, and the adhesive can be used as shown in the figure, or a mechanical fixing device such as a metal bracket can be used. In the springless lotion pump of the present invention, a novel upper check valve 7 is employed. The upper check valve 7 includes an elastic tube 71 and a valve seat cut. The valve seat 4a is a part of the connecting duct 4 having a closed top end and at least one opening 4al provided on the side. The elastic tube 71 is fitted outside the valve seat 4a. Prior to assembly, the inner diameter of the elastic tube 71 is slightly smaller than the outer diameter of the valve seat cut. Therefore, after the assembly is completed, the elastic tube 71 elastically covers the side of a and closes the opening 4a1. The upper check valve 7 is normally at 1. status. When the pressure in the vapor tube 6 reaches a certain value, the elastic tube is opened at the opening 4al, so that the emulsion is pumped through the indenter 2. When the pressure drops below a certain value, the elastic #71 recloses the opening W, thereby stopping the liquid discharge. Further, in order to ensure that the elastic tube 71 does not fall off the partition 4a, it is preferable to provide at least one projection 4 on the valve seat 4a. The basic operation of the springless emulsion pump of the present invention is as follows. When the operator lowers the fortune 2, if the dust force in the steam rainbow 6 reaches a certain value, the upper check valve 7k is opened, the lower check valve 8 is closed, and the emulsion is pumped from the indenter 2. When the field pulls the indenter 2 upwards, the upper check valve 7 is closed, and the inner one-way bamboo emulsion is sucked into the pump chamber by the suction pipe 9, and the sergeant 2 injects the liquid. The emulsion pump of the present invention is easy to recycle and reuse, and is environmentally friendly. In addition, the springless lotion pump is also very suitable for the case where the liquid is highly corrosive to metal springs, such as pumping fluoride toothpaste. In the case where a spring is not provided to the lotion pump, the following problems may occur if the conventional upper check valve consisting of a bead and a valve seat is used. It is possible to stop using the lotion when the indenter is not pressed to the bottom dead center. At this time, since the upper one-way valve must be open (otherwise it will not be discharged), the weight of the indenter, the connecting pipe and the piston, and the weight of the emulsion therein will cause the piston to continue to descend slowly, thereby forming at the nozzle of the indenter. Slow drops. This is not the case with a spring pump, because the spring always presses the piston up and there is no possibility that the piston will automatically descend. In the case of prior art spray pumps, a small spring is placed over the piston which forces the piston down and allows the upper check valve to remain closed. Thus, only when the pump chamber pressure reaches a certain value, this pressure pushes the piston upward against the force of the small spring, thereby opening the upper check valve. However, this still requires the use of a spring and cannot achieve the purpose of no spring. Since the present invention contemplates a novel one-way valve structure for liquid contents, it is possible to achieve the above-mentioned leakage problem by achieving a "springless design" while well achieving 12 丄W4〇87. Figure 7 - Figure 9 shows a spray pump 20 according to a second embodiment of the present invention. The spray pump 20 mainly comprises a nozzle 21, a pressure head 22, a mouthpiece 23, a piston rod 24, a return spring 25, a cylinder 26, an upper check valve 27, The check valve 28, the suction pipe 29 and the gasket 200 are shown in Fig. 7. Fig. 7 shows the state in which the ram 2 is in the upper position. Fig. 8 shows the state in which the ram 2 is pressed. As shown, the nozzle 21 is placed at the pressure. The front end of the head 22. The indenter 22 is coupled to one end of the piston rod 24. The piston rod 24 reciprocates within the cylinder 26. The mouthpiece 23 is coupled to the upper end of the cylinder 26 and has a connection structure 23 for attaching a mouth of the container. A spring 25 is disposed between the ram 22 and the mouthpiece 3 for resetting the piston rod 24 and the ram 22 after being pressurized. The lower check valve 28 is disposed at the lower end of the cylinder 26. The lower unidirectional chamber 28 includes a The bead 281 and the valve seat 261, the valve seat 261 can be integrally formed on the cylinder 26. 29 is attached to the lower end of the cylinder 26. A gasket 2 还 can also be provided in the mouthpiece 23 to form a good seal with the mouth of the container. The spray pump is characterized in that it employs an upper one in accordance with the present invention. The upper 27' is similar to the upper one-way valve in the springless emulsion pump described above. The upper check valve 27 includes an elastic tube 271 and a valve seat 24. The valve seat 241 is a portion of the piston rod 24 having a closed top end And at least one opening 2411 provided on the side. The elastic tube 271 elastically covers the side of the valve seat 241 and closes the opening 241. In addition, in order to ensure that the elastic tube 27 does not fall off the valve seat 241, preferably in the valve At least one protrusion 13 1324087 is provided on the seat 241 from 2412. In the case of the spray pump, the higher the internal pressure, the better the spray effect. In the case of using the upper one-way head 27 according to the present invention, it is possible to produce a comparison in the pump chamber. There is no need to additionally provide a small spring for forcing the piston to descend. The greater the restraining force of the elastic tube 271, the greater the internal pressure in the pump chamber, and the better the effect of the spray.
