DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0031] like Figure 1-Figure 10 As shown, the present invention provides a liquid cooling pipeline conversion stop joint, comprising: a connector 1, and a male head body 2 arranged at one end of the connector 1; the connector 1 is mainly used to connect the present invention with a water nozzle, and the connector 1 can be as follows Figure 4 The male connector shown in the figure may also be a female connector. In order to increase the application scenarios of the present invention, the following is usually adopted: Figure 4 The male head shown in the figure is provided with a female conversion joint on it, and the two together constitute a connecting piece 1. According to the actual situation of the faucet, it is selected to directly connect with the (female) faucet, or to install the female conversion joint and then plug the connecting piece 1 with the (male) faucet. The male head body 2 is tubular and connected with the connecting piece 1. The outer wall of the male head body 2 is provided with a limit assembly for connecting with the female joint. The male head body 2 is provided with a first reset member 3 and a male head valve head 4. The male head valve head 4 is located at the opening of the male head body 2 and is connected to the connecting piece 1 through the first reset member 3. Figure 1As shown, under normal conditions, the male valve head 4 seals the male body 2 under the action of the first reset member 3. In this state, the present invention only needs to be installed on the faucet through the connector 1 to achieve the effect of liquid cutoff. The combined action of the liquid and the first reset member 3 can increase the firmness of the seal between the male valve head 4 and the male body 2, so that the male valve head 4 will not be easily pushed. When the present invention is connected to the female connector, a female valve stem 7 is required to be provided in the female connector, such as Figure 4 As shown, it is used to push the male valve head 4, such as Figure 5 As shown, the force exerted by the female valve stem 7 on the male valve head 4 is opposite to the direction of liquid flow. Figure 3 As shown in , when the present invention is connected to the female connector, the female valve stem 7 will allow the male valve head 4 to compress the first reset member 3, and the liquid can flow to the female connector through the present invention. The inner diameter of the male body 2 is larger than the inner diameter of the connector 1, so that the interior of the male body 2 can form a card table for the first reset member 3 to abut. A limit ring 21 is provided on the inner side wall of the male body 2, and the limit ring 21 is located at the opening of the male body 2, and the inner diameter of the limit ring 21 is smaller than the inner diameter of the male body 2, and the male valve head 4 is movably connected to the limit ring 21. The male valve head 4 is composed of a sealing portion 41 movably connected to the limiting ring 21, and a clamping portion 42 arranged on the outer wall of the sealing portion 41. The diameter of the sealing portion 41 is adapted to the inner diameter of the limiting ring 21, so that the sealing portion 41 can be inserted into the limiting ring 21. The outer diameter of the clamping portion 42 is adapted to the inner diameter of the male body 2. One end of the first reset member 3 abuts against the connecting member 1, and the other end abuts against the clamping portion 42, so that under the action of the first reset member 3 and the liquid pressure, the male valve head 4 will not fall out of the male body 2. The outer wall of the sealing portion 41 is provided with an annular groove, and a first sealing member 43 is arranged in the annular groove. The first sealing member 43 can be a sealing ring, which is sleeved on the outside of the sealing portion 41 to increase the sealing performance. The end of the clamping portion 42 away from the sealing portion 41 is provided with an annular clamping groove, and a clamping ring 44 is provided in the clamping groove. The end of the first reset member 3 abuts against the clamping ring 44, and the clamping ring 44 provides an abutting position for the first reset member 3. Figure 1 , 2 shown.

[0032] When the liquid cut-off function of the present invention is needed, the present invention only needs to be directly installed on the faucet. Under the dual forces of the liquid pressure and the first reset member 3, the clamping portion 42 abuts against the limiting ring 21. At this time, the sealing portion 41 is located inside the limiting ring 21, thereby preventing the liquid from flowing out.

[0033] When the present invention needs to pass water, it is only necessary to plug the female connector with the female valve stem 7 into the male body 2. After plugging, the female valve stem 7 can push the male valve head 4 into the male body 2, compressing the first reset member 3. At this time, the male body 2 is connected to the female connector. After the female connector is removed, under the action of the first reset member 3 and the liquid pressure, the sealing part 41 is inserted into the limit ring 21 again to achieve liquid cutoff.

[0034] In the previous embodiment, we mentioned that the male valve head 4 can be pushed by the female valve stem 7. Because the male valve head 4 is subjected to the dual forces of the first reset member 3 and the liquid pressure, a large force is required to push the male valve head 4, and it is usually necessary to use a tool to push it to move. When the present invention is used as a plug, if you want to confirm whether there is liquid in the container or tube installed with the present invention, you can use the push of the male valve head 4 to observe whether there is liquid flowing out as a judgment standard. However, after the male valve head 4 is pushed into the male body 2, if there is liquid (in the container or tube), or the liquid pressure is large, the liquid will be sprayed along the central axis direction of the male body 2, and its spraying amount and spraying pressure are large, which can easily cause pollution to the surrounding environment of the present invention, for example, spraying on the wall or adjacent equipment. Therefore, a test device can be set on the sealing part 41 as another embodiment to confirm whether there is liquid in the container or tube connected by the present invention, and at the same time, it will not cause spraying. When the outer wall of the sealing part 41 is sealed and connected to the inner wall of the limit ring 21, the interior of the male body 2 is selectively connected to the outside through the test device. That is, when it is necessary to confirm whether there is liquid, it is only necessary to operate the test device.

[0035] In this embodiment, we provide a testing device as a second implementation of the present invention. The testing device is a first testing device 5. The sealing portion 41 is provided with a first flow groove 411 and a second flow groove 412 which are connected to each other. The first testing device 5 is composed of a second reset member 51 and a movable member 52. The opening of the first flow groove 411 faces the first reset member 3, and the opening of the second flow groove 412 faces the direction away from the first reset member 3. The inner diameter of the first flow groove 411 is smaller than the inner diameter of the second flow groove 412, and the inner diameter of the second flow groove 412 is smaller than the outer diameter of the sealing portion 41. The inner diameter of the connection between the first flow groove 411 and the second flow groove 412 is smaller than the inner diameter of the first flow groove 411, and the interior of the first flow groove 411 is provided with an inclined surface with a gradually decreasing diameter, such as Figure 7As shown, through the inclined surface, the inner diameter of the first circulation groove 411 is gradually reduced to the inner diameter of the connection point between the first circulation groove 411 and the second circulation groove 412. One end of the movable member 52 is located in the first circulation groove 411, and the other end extends into the second circulation groove 412 and is connected to the second circulation groove 412 through the second reset member 51. The movable member 52 is composed of a sealing end 521 located in the first circulation groove 411, a limiting end 522 located in the second circulation groove 412, and a connecting section 523, as shown in FIG. Figure 8 As shown, the sealing end 521 is hemispherical, one end of the connecting section 523 is connected to the arc-shaped end of the sealing end 521, and the other end is connected to the limiting end 522. The limiting end 522 is centered on the connecting section 523 and extends radially away from the connecting section 523. A support leg extending in the direction of the first flow groove 411 is provided at the end of the limiting end 522. The second reset member 51 is sleeved on the connecting section 523 and is located in the second flow groove 412. When using the first test device 5, a tool can be used or the limiting end 522 can be directly pressed with a finger until the support leg of the limiting end 522 abuts against the inner end surface of the second flow groove 412. The area of ​​the second flow groove 412 can be adapted to the size of the thumb of an adult. The elastic force of the second reset member 51 is much smaller than the elastic force of the first reset member 3. Its function is to reset the sealing end 521 when there is no liquid pressure (that is, there is no liquid in the container or pipeline equipped with the present invention). The sealing end 521 abuts against the inclined surface of the first circulation groove 411, and can achieve sealing by relying on liquid pressure. Since the circulation area of ​​the first circulation groove 411 is small, the pressure generated on the sealing end 521 is relatively small. Therefore, only the pressing of a finger can make the limiting end 522 squeeze the second reset member 51, so that the connecting section 523 moves horizontally, thereby pushing the sealing end 521 away from the inclined surface of the first circulation groove 411. Since the opening area of ​​the second circulation groove 412 is adapted to the size of an adult's fingertip, after pressing, the ejected liquid will accumulate in the second circulation groove 412. When the finger is removed, the sealing end 521 is pushed to reset under the liquid pressure, and then by checking whether there is liquid in the second circulation groove 412, it can be judged whether there is liquid in the container or pipeline installed with the present invention.

[0036] In the second embodiment, we provide a test device that can be pressed by hand to determine whether there is liquid in the container or pipeline installed with the present invention. However, the above embodiment is only for liquids that will not cause harm to the human body. For some toxic and harmful liquids, the above embodiment will cause damage to the human body. Therefore, for some liquids that are harmful to the human body, we provide a third embodiment. In this embodiment, the test device is a second test device 6, and the side wall of the limit ring 21 is provided with at least one first through hole 211, such as Fig. 9As shown, the sealing portion 41 is connected to the clamping portion 42 through the second testing device 6, and the second testing device 6 is composed of an outer connecting portion 61 connected to the sealing portion 41 and the clamping portion 42, and an inner connecting portion 62 arranged inside the outer connecting portion 61. Fig.10 As shown, the outer communication part 61 is provided with a second through hole 611, the inner communication part 62 is provided in the second through hole 611, and is movably connected to the sealing part 41 through a transmission member 63, one end of the transmission member 63 is connected to the end of the inner communication part 62, and the other end is connected to the sealing part 41 through a rotating component such as a friction pair or a bearing. Usually, a card slot is provided at the end of the transmission member 63, and the card slot can be a straight line, such as Fig.10 As shown, it is a cross or a hexagon, so that the transmission part 63 can be rotated by a corresponding screwdriver or hexagonal wrench to rotate the internal connecting part 62. The side wall of the external connecting part 61 is provided with at least one third through hole 612 adapted to the first through hole 211, and the internal connecting part 62 is provided with a fourth through hole 621 connected to the inside of the male head body 2, and at least one fifth through hole 622 adapted to the third through hole 612. The external connecting part 61 is used for the installation of the sealing part 41 and the clamping part 42. Although the external connecting part 61 may not be provided, and the connection and fixation of the clamping part 42 and the sealing part 41 are directly completed through the internal connecting part 62, if the embodiment without the external connecting part 61 is adopted, when the internal connecting part 62 is rotated, the clamping part 42 will also rotate together, which may cause the first reset member 3 to be twisted, thereby affecting its service life. Therefore, a dual connection mode of the inner connecting part 62 and the outer connecting part 61 is usually adopted. When the inner connecting part 62 rotates, the liquid can flow out from the fourth through hole 621, the fifth through hole 622, the third through hole 612, and the first through hole 211. By adjusting the axial spray in the first embodiment to radial spray, it is avoided that the liquid splashes on the person when it flows out, causing harm to the person. After solving the problem of the liquid outflow direction, this embodiment also optimizes the liquid outflow speed to avoid the liquid from being sprayed out. The outer wall and the inner wall of the outer connecting part 61 are both provided with a second sealing member 613. In addition to the sealing function, the second sealing member 613 reserves a rectangular release hole at the position of the second through hole 611, such as Fig.10 As shown, the opening area of ​​the release hole is larger than the cross-sectional area of ​​the second through hole 611. During the rotation of the inner communication part 62, the fifth through hole 622 will be connected to the third through hole 612 through the release hole. At this time, the liquid ejected from the fifth through hole 622 will first hit the inner wall of the outer communication part 61 to release the kinetic energy, and then slowly flow out from the third through hole 612. The principle is the same as the kinetic energy release principle inside the faucet. In this embodiment, the kinetic energy of the liquid is released by adding a release hole on the second sealing member 613 to prevent the liquid from being ejected.
