[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 4 As shown, the pointed nozzle combined round core PE stop valve pipe cover provided in this embodiment includes a hose 1, a stop valve port 2 is opened at the upper end of the hose 1, and a pointed nozzle 3 is arranged above the hose 1, a stop valve valve 4 is slidably connected to the lower end of the pointed nozzle 3, and the stop valve valve 4 corresponds to the stop valve port 2, a discharge port 5 is opened at the upper end of the pointed nozzle 3, and a stop valve spring 6 is arranged between the hose 1 and the pointed nozzle 3, one end of the stop valve spring 6 is fixedly connected to the hose 1, and the other end of the stop valve spring 6 is fixedly connected to the pointed nozzle 3, and the outer side of the pointed nozzle 3 is provided with a stop valve 4. A tube cover 7 is provided, and the tube cover 7 is unscrewed. The pointed nozzle 3 pinches the hose 1 downward with force, and the paste flows to the stop valve port 2. The stop valve port 2 is squeezed open by the pressure of the paste, and the stop valve valve 4 slides toward the inside of the pointed nozzle 3, and the paste flows out. When the hose 1 is not released forcefully, the stop valve port 2 is squeezed by the pressure of the stop valve spring 6, so that the stop valve valve 4 and the stop valve port 2 are abutted against each other, and the stop valve port 2 is closed. At this time, the paste will not flow out, and air, dust, bacteria, etc. can be prevented from entering the tube, so that consumers have a better experience when using the product.

[0023] Further, such as Figure 1-Figure 4 As shown, a slide groove 8 is provided at the upper end of the hose 1, and the slide groove 8 is slidably connected to one end of the nozzle 3. The nozzle 3 slides on the slide groove 8, so that the nozzle 3 can adapt to different usage scenarios and needs.

[0024] Further, such as Figure 1-Figure 4 As shown, a slot 9 is provided on the tube cover 7, and the slot 9 abuts against the end of the tip 3 away from the hose 1. When the slot 9 abuts against the tip 3, the tip 3 can be fixed and protected to prevent it from being damaged by collision during transportation or storage.

[0025] Further, such as Figure 1-Figure 4 As shown, a plug 10 is fixedly installed on the tube cover 7, and the plug 10 abuts against the discharge port 5. When the tube cover 7 and the hose 1 are closed, the plug 10 abuts against the discharge port 5, thereby blocking the discharge port 5 to prevent the paste inside the hose 1 from leaking, thereby enhancing the overall sealing.

[0026] Further, such as Figure 1-Figure 4 As shown, an external thread 11 is provided at one end of the hose 1 near the nozzle 3, and an internal thread 12 is provided on the inner side of the tube cover 7. The internal thread 12 corresponds to the external thread 11, and the tube cover 7 and the hose 1 are tightly combined through the threaded connection to enhance the sealing performance and prevent leakage of the material in the tube; at the same time, the threaded connection method makes the tube cover 7 easy to install and disassemble, and is convenient for using and storing the paste in the tube.

[0027] like Figure 1-Figure 4 As shown, the principle of the pointed combined round core PE stop valve pipe cover provided in this embodiment is as follows:

[0028] When in use, first unscrew the tube cover 7, and use the pointed nozzle 3 to pinch the hose 1 downward, so that the paste flows to the stop valve port 2. The stop valve port 2 is squeezed open by the pressure of the paste, and the stop valve valve 4 slides toward the inside of the pointed nozzle 3, so that the paste flows out. When the hose 1 is not released forcefully, the stop valve port 2 is squeezed by the pressure of the stop valve spring 6, so that the stop valve valve 4 and the stop valve port 2 are against each other, so that the stop valve port 2 is closed. At this time, the paste will not flow out, thereby preventing air, dust, bacteria, etc. from entering the tube, allowing consumers to have a better experience when using the product.

[0029] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0030] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0031] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
