[0022] Figure 2 A schematic diagram of the structure of a new valve proposed by the utility model Figure 2 . DETAILED DESCRIPTION

[0023] Reference Figure 1-2 The utility model proposes a new type of valve, comprising:

[0024] Valve stem 1, valve stem 1 comprises a first tube body portion 11 with a central hole and a first seat body portion 12 connected to the first tube body portion 11, the top of the central hole is open, and the bottom is blocked by the first seat body portion 12, and at least one opening connected to the central hole is opened on the side wall of the bottom of the first tube body portion 11. Bowl body 2, bowl body 2 has a through flow guide hole, bowl body 2 is a bowl-shaped structure comprising a first annular side portion 21 and a first bottom portion 22, an annular portion 23 with a first mounting hole extends from the bowl mouth of bowl body 2, the first tube body portion 11 is sleeved in the first mounting hole and the first seat body portion 12 is received in the bowl body 2, and the first seat body portion 12 has a first annular sealing surface that forms a seal with the annular portion 23. Sealing cup 3, sealing cup 3 is a cup-shaped structure comprising a second annular side portion and a second bottom, the top of the second annular side portion is folded outward to form an annular groove 31 that can be assembled to the open part of a container, the center of the second bottom has a second mounting hole that penetrates the second bottom, and the annular portion 23 is annularly sealed and clamped in the second mounting hole.

[0025] When in use, the annular groove 31 is assembled to the open mouth of the container to seal the mouth of the container. The valve stem 1 is pressed down to open the valve. At this time, the first seat body 12 is separated from the annular portion 23, and the opening on the side wall of the first tube body 11 enters the interior of the bowl body 2. The liquid in the container enters the bowl body 1 through the guide hole at the bottom of the bowl body 1, and enters the middle hole of the first tube body 11 through the opening on the side wall of the first tube body 11, and is sprayed out from the top of the middle hole; the valve stem 1 moves up to reset the valve to close. At this time, the first annular sealing surface of the first seat body 12 abuts against the annular portion 23 again and forms a seal on the abutting surface of the two.

[0026] In a further embodiment, a second annular sealing surface 231 is provided between the inner wall of the first hole section of the first mounting hole and the outer wall of the first tube body portion 11. When the valve is opened, the first seat body portion 12 is separated from the annular portion 23, so that the material in the tank enters the valve stem 1 through the opening on the side wall of the valve stem 1 and is discharged from the valve stem 1, while the second annular sealing surface 231 blocks the material from flowing out from the outside of the valve stem 1. When the valve is closed, the first seat body portion 12 contacts the annular portion 23 again.

[0027] In a further embodiment, a sealing member 4 is sleeved on the first tube body 11, the sealing member 4 is located above the annular portion 23, and the lower end of the sealing member 4 abuts against the annular portion 23. The sealing member 4 also forms a new seal above the second annular sealing portion 231 to further enhance the sealing performance between the valve stem 1 and the external space.

[0028] In a further example, an elastic member 5 is further included to provide elastic support for the valve stem 1 in the axial direction thereof.

[0029] Specifically, the elastic member 5 is sleeved on the first tube body 11 and its top end abuts against the limiting cap 6 arranged on the first tube body 11, and its bottom end abuts against the second seat body 42. Figure 1 Alternatively, the elastic member 5 is disposed in the bowl body 2 and abuts against the first seat portion 12 and the bottom of the bowl body 2, as shown in FIG. Figure 2 shown.

[0030] When the elastic member 5 is sleeved on the first tube body portion 11 and its top end abuts against the limiting cap 6 arranged on the first tube body portion 11, the specific structure of the sealing member 4 is: it has a second tube body portion 41 and a second seat body portion 42 connected to the second tube body portion 41, the first mounting hole also includes a second hole section connected to the first hole section and located above the first hole section, the second tube body portion 41 is received in the gap between the inner wall of the second hole section and the outer wall of the first tube body portion 11, and abutment is formed between the lower wall of the second seat body portion 42 and the top wall of the annular portion 23. When the valve stem 1 is pressed down to enter the open state, the elastic body 5 applies pressure to the second seat body portion 42 to transfer the pressure to the annular portion 23 through the second seat body portion 42, thereby causing the annular portion 23 to be squeezed so that the second annular sealing surface 231 firmly holds the valve stem 1, thereby effectively avoiding the problem of peripheral leakage of the valve stem 1; at the same time, it can also assist the compression spring 7 to provide assistance for the resetting of the valve stem 1.

[0031] When the elastic member 5 is arranged in the bowl body 2, the sealing sleeve 6 is made of a soft plastic member, and its top end is limited by a matching cap 7 assembled on the valve stem 1. When the valve stem 1 is pressed down to enter the open state, the sealing sleeve 6 also enters a compressed state, so that its inner hole shrinks, and then its inner wall tightly hugs the valve stem 1, thereby effectively avoiding the problem of peripheral leakage of the valve stem 1; at the same time, it can also assist the compression spring 7 to provide assistance for the valve stem 1 to reset.

[0032] In a further embodiment, the top wall of the first seat body 12 blocking the middle hole and the first annular sealing surface thereof are arranged at a high and low position, the first seat body 12 has a truncated cone located between the top wall and the first annular sealing surface thereof, and the annular portion 23 has a plurality of sealing ribs 8 that can form a third annular sealing surface with the side wall of the truncated cone, so as to further increase the sealing effect and reduce the risk of leakage.

[0033] In a further embodiment, the bottom end of the first seat body portion 12 has a groove to make the groove wall thickness uniform, so as to ensure uniform force on the first seat body portion 12 .

[0034] In a further embodiment, the first bottom portion 22 is detachably connected to the first annular side portion 21, and an annular seal is formed between the first bottom portion 22 and the first annular side portion 21. This structural design allows the bottom of the bowl body 2 to be opened, so that the valve stem 1 can be installed and removed from the lower end of the bowl body 2.

[0035] Specifically: the first bottom 22 includes a bottom surface located at the bottom of the first annular side portion 21 and an annular surface attached to the outer circumferential surface of the first annular side portion 21; the outer circumferential surface of the first annular side portion 21 is provided with an annular outer groove, and the annular surface of the first bottom 22 is provided with an inner groove opposite to the outer groove and cooperating with the outer groove to form an annular cavity therebetween, and a sealing ring 10 is provided in the annular cavity, so that the sealing ring 10 can be used to realize the detachable assembly of the first bottom 22 and the first annular side portion 21 and form a seal.

[0036] In a further embodiment, a guide hole is opened on the first bottom 22 , and a guide tube 9 communicating with the guide hole is installed on the first bottom 22 . When the valve is opened, the material in the tank enters the bowl body 1 through the guide tube 9 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
