Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1As shown, an embodiment of the present invention provides a control valve assembly, which includes: a cover body 10 and a one-way valve assembly 20. The cover body 10 has a liquid inlet 10a, a liquid outlet 10b and a first circulation channel. The liquid inlet 10a and the liquid outlet 10b are respectively connected to the first circulation channel. The cover body 10 has a first connection structure 10c. The cover body 10 can be connected to the bottle mouth of the bottle body 60 through the first connection structure 10c. The liquid inlet 10a is used to communicate with the bottle mouth. Through the above structure, the first connection structure 10c can be used to connect with the bottle body 60. The liquid in the bottle body 60 passes through the liquid inlet 10a and the first circulation channel in sequence, and finally flows out from the liquid outlet 10b. The one-way valve assembly 20 is movably arranged in the first circulation channel. The one-way valve assembly 20 has an initial state of blocking the liquid outlet 10b and an open state of opening the liquid outlet 10b. The one-way valve assembly 20 can be used to prevent liquid from flowing out of the bottle body 60 in the initial state. When the bottle body 60 is inverted, the one-way valve assembly 20 is switched to the open state to allow the fluid to flow out. This facilitates the installation of the bottle body 60 and does not affect the normal use of the bottle body 60.

[0029] By using the technical solution provided by the present application, the cover 10 is used to connect with the bottle mouth of the bottle body 60, the one-way valve assembly 20 is arranged in the first circulation channel, and the one-way valve assembly 20 has an initial state of blocking the liquid outlet 10b and an open state of opening the liquid outlet 10b. Through the above device, when the bottle body 60 is inverted, the cover 10 can be installed on the bottle mouth, and the one-way valve assembly 20 can be used to block the liquid outlet to prevent the liquid from spilling out of the bottle mouth when inverted. When the liquid needs to flow out, the one-way valve assembly 20 can be switched to the open state, which is convenient for users to use.

[0030] Furthermore, in the present application, the one-way valve assembly 20 is directly installed in the cover body 10, which can simplify the device structure, reduce production costs, and miniaturize the product.

[0031] In this embodiment, the cover body 10 is configured as a split structure, which can reduce the processing difficulty and cost and facilitate disassembly and assembly by the staff.

[0032] like Figure 2 and Figure 4As shown, the cover body 10 is connected to the bottle body 60 through a threaded structure. Specifically, the first connection structure 10c includes an internal thread. The cover body 10 includes: an upper shell 11 and a lower shell 12. Specifically, an annular groove 113 is provided on the upper shell 11, and an internal thread is provided on the side wall of the annular groove 113. The internal thread is used for threaded connection with the bottle mouth. The middle part of the upper shell 11 has a first communication hole 111, and the first communication hole 111 is located in the inner circle of the annular groove 113. The liquid inlet 10a is provided on the upper shell 11, and the liquid inlet 10a is connected with the first communication hole 111. The lower shell 12 is connected to the upper shell 11, and the middle part of the lower shell 12 has a second communication hole 121. The liquid outlet 10b is provided on the lower shell 12, and the liquid outlet 10b is connected with the second communication hole 121. The second communication hole 121 cooperates with the first communication hole 111 to form a first circulation channel. Specifically, a sealing protrusion 52 is further provided at the bottom of the annular groove 113. The sealing protrusion 52 is provided in an annular shape and is used to fit and seal with the end of the bottle mouth to improve the sealing effect.

[0033] The lower shell 12 and the upper shell 11 may be connected by welding, plug-in structure, threaded structure or other structures.

[0034] Specifically, the one-way valve assembly 20 includes: a valve core 21 and a return spring 22. The valve core 21 is movably arranged in the first circulation channel, and the valve core 21 is located at the liquid outlet 10b. One end of the return spring 22 is connected to the valve core 21, and the other end of the return spring 22 is connected to the inner wall of the first circulation channel. The return spring 22 is used to keep the valve core 21 in the initial state. The above scheme has a simple structure, is easy to design and install, and when it is necessary to switch to the open state, the liquid outlet 10b can be opened by simply pushing the valve core 21 open with external force. When the external force is removed, the valve core 21 presses against the liquid outlet 10b under the action of the elastic force of the return spring 22, so that the one-way valve assembly 20 returns to the initial state. Specifically, the valve core 21 is a sphere.

[0035] In this embodiment, a locking structure 131 is provided on the lower shell 12, and a locking groove 132 is provided on the upper shell 11. The locking structure 131 has a locking position and a disengaging position relative to the locking groove 132. When the locking structure 131 is in the locking position, the locking structure 131 is clamped in the locking groove 132; when the locking structure 131 is in the disengaging position, the locking structure 131 withdraws from the locking groove 132. The upper shell 11 and the lower shell 12 are locked and fixed by the locking groove 132 and the locking structure 131, and the structure is simple and convenient for disassembly and assembly.

[0036] like Figures 2 to 6As shown, the locking structure 131 includes a plurality of locking protrusions arranged at intervals in the annular direction, and the locking groove 132 includes a main groove section 1321 and a matching groove section 1322 which are connected to each other. The main groove section 1321 is arranged around the periphery of the lower shell 12, and the main groove section 1321 is located above the matching groove section 1322; there are a plurality of matching groove sections 1322, and the plurality of matching groove sections 1322 are arranged one by one with the plurality of locking protrusions, and each matching groove section 1322 is adapted to the shape of the locking protrusion, so that each locking protrusion enters the main groove section 1321 after passing through the corresponding matching groove section 1322 for locking. By providing a plurality of locking protrusions, the assembly stability of the upper shell 11 and the lower shell 12 can be improved. Specifically, the plurality of locking protrusions are evenly spaced and arranged on the lower shell 12.

[0037] For ease of assembly, a chamfered structure 133 may be provided on the locking protrusion and / or the locking groove 132 to reduce friction between the locking protrusion and the locking groove. In this embodiment, the chamfered structure 133 is provided at the connection between the matching groove section 1322 and the main body groove section 1321.

[0038] The outer periphery of the first communication hole 111 is provided with an annular avoidance groove 114, and the lower shell 12 is partially inserted in the annular avoidance groove 114. With the above structure, after the lower shell 12 is screwed into the main body groove section 1321 through the locking protrusion, the upper end of the lower shell 12 is inserted in the annular avoidance groove 114, so that the upper shell 11 and the lower shell 12 can be assembled tightly, and the sealing between the first communication hole 111 and the second communication hole 121 is improved.

[0039] In this embodiment, a sealing mechanism 51 is provided between the upper shell 11 and the lower shell 12, so that the sealing performance between the upper shell 11 and the lower shell 12 can be further improved. Specifically, a sealing protrusion is provided in an annular shape on the end surface of the first communication hole 111, and a stepped surface is provided in the second communication hole 121 of the lower shell 12. After the upper shell 11 and the lower shell 12 are assembled through the locking protrusion and the locking groove 132, the sealing protrusion abuts against the stepped surface to complete the sealing between the two.

[0040] The diameter of the liquid inlet 10a is gradually increased in the direction close to the liquid outlet 10b, so that the liquid in the bottle body 60 can be throttled.

[0041] The liquid outlet 10b has a reduced diameter section, the diameter of which gradually decreases in the direction away from the liquid inlet 10a. The valve core 21 is arranged close to the liquid outlet 10b. The reduced diameter section is blocked by the valve core 21, which can improve the blocking effect. When the liquid outlet 10b needs to be opened, the valve core 21 can be easily moved out of the reduced diameter section.

[0042] In this embodiment, an air inlet channel 10d is provided on the cover body 10, one end of the air inlet channel 10d is connected to the outside, and the other end of the air inlet channel 10d is used to communicate with the inside of the bottle. By providing the air inlet channel 10d, the pressure difference between the bottle body 60 and the outside can be reduced, so that the liquid in the bottle can flow out smoothly.

[0043] The air intake passage 10d may be arranged only on the upper shell 11, or may be arranged through the upper shell 11 and the lower shell 12. Specifically, an air intake column 112 is arranged on the upper shell 11, and the air intake column 112 has an air intake hole arranged through it. An air intake groove 122 is arranged on the outer side wall of the lower shell 12, and the air intake groove 122 extends along the axial direction of the lower shell 12.

The air intake hole and the air intake groove 122 do not need to be arranged on a vertical line, and their extension positions may be staggered, as long as they can be connected. In this embodiment, Figure 6 As shown, the lower shell 12 is provided with an avoidance structure 123, and by providing the avoidance structure 123, a gap can be provided between the outer wall of the lower shell 12 and the inner wall of the upper shell 11, so that the air inlet hole and the air inlet groove 122 can be communicated through the avoidance structure 123. Specifically, the avoidance structure 123 is a section structure. In addition, an air guide tube 70 can be provided on the air inlet column 112 to lengthen the length of the air inlet hole through the air guide tube 70, so that the air inlet port is closer to the bottom of the bottle, and liquid is prevented from flowing out of the air inlet port.

[0044] Through the control valve assembly provided in the present application, the one-way valve assembly 20 can be used to block the liquid outlet 10b in the initial state. After the bottle body 60 is inverted, the fluid can be flowed out for use by switching to the open state.
