Description

Technical Field

[0001] This utility model relates to the field of water jet technology, specifically a water bag water jet. Background Technology

[0002] Existing water bag dispensers typically use a straight-through tube with an independent valve core or plug to control the flow. The procedure is as follows: first, open the dispenser on the water bag; then, quickly connect the female connector of the water supply device (such as a water dispenser or booster pump) to the inlet of the dispenser and maintain a seal; subsequently, turn on the water supply device to fill the soft water bag; after filling, the operator must first disconnect the female connector from the dispenser's plug or threaded connection, and then rotate or push / pull the valve core on the dispenser to shut off the water flow. This type of device is widely used in scenarios such as filling household hot water bags, and it has a simple structure and low manufacturing cost.

[0003] However, in the application of soft or hot water bags, the above sequence of first disconnecting the female connector and then closing the valve is prone to causing the hose to deform and pull due to the release of pressure inside the water bag, resulting in water leakage or even splashing. When transporting high-temperature liquids, the leaked hot water may cause scalding. In addition, it increases the operation time and the probability of malfunction. If the valve core is not aligned or the sealing surface is worn, water leakage may occur, leading to scalding and wasting water resources. There is an urgent need for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a water bag pump head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water bag dispenser head, comprising: a connecting seat for connecting to a water bag; a water injection pipe vertically installed above the connecting seat, with a water permeable hole at the connection point between the water injection pipe and the connecting seat; a water inlet hole, comprising a first water inlet section and a second water inlet section, both the first and second water inlet sections being located inside the water injection pipe, a cap being installed at the first water inlet section, and the second water inlet section communicating with the water permeable hole; and a sealing assembly capable of rotating around the axis of the water injection pipe and displacing axially to selectively open and close the water permeable hole.

[0006] In one feasible implementation, the first water inlet section and the second water inlet section are stepped transitions in the axial direction, with the stepped surface forming the abutment end.

[0007] In one feasible implementation, the sealing assembly includes: a spiral guide groove, two spiral guide grooves respectively formed on the outer side of the outer wall of the connecting seat; a rotating cap, two sliders are provided on the inner side of the rotating cap, and the rotating cap is movably disposed at the two spiral guide grooves via the two sliders; a plug, one end of the plug is fixedly installed on the inner side of the rotating cap, the outer edge of the plug is tightly fitted with the second water inlet section, and the other end of the plug can selectively abut against the abutment end.

[0008] In one feasible implementation, the inner side of the abutting end and the rotating cap is provided with a rubber gasket to increase sealing.

[0009] In one feasible implementation, each end of the two spiral guide grooves is provided with a locking block for locking the rotating cap.

[0010] In one feasible implementation, a positioning disk is coaxially connected to the outer side of the connecting seat. The diameter of the positioning disk is larger than the diameter of the connecting seat, and the positioning disk is used to form a stop and position when connected and pressed against the water bag, thereby improving the sealing reliability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This device designs the first and second water inlet sections as axial stepped transitions, so that the stepped surfaces naturally form the abutment ends, thereby providing a stable stop reference for the plug body during opening and closing. With the spiral guide groove and slider of the sealing component, synchronous rotation and axial displacement can be achieved under a single rotational action, which not only ensures precise and controllable opening and closing stroke, but also avoids multiple operations; the outer edge of the plug body continuously fits against the second water inlet section, and a seal is established at the abutment surface under the elastic compensation of the rubber gasket; the locking block at the end of the spiral guide groove locks immediately after the rotating cap is in place, preventing vibration and loosening and providing a clear closing position; water can be quickly injected or blocked without multiple adjustments or additional fasteners, so the operation is simple, and it has a highly reliable seal, clear opening and closing positioning and anti-loosening, ensuring safe, efficient and leak-free operation of water flow during injection and blocking.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a water bag water dispenser, comprising: a connecting seat 1, a water injection pipe 2, a water inlet 3, and a sealing assembly. The connecting seat 1 is used to connect to the water bag; the water injection pipe 2 is vertically installed above the connecting seat 1, and a water permeable hole 9 is provided at the connection between the water injection pipe 2 and the connecting seat 1; the water inlet 3 includes a first water inlet section 31 and a second water inlet section 32, both of which are located inside the water injection pipe 2. A cap 10 is also installed at the first water inlet section 31, and the second water inlet section 32 communicates with the water permeable hole 9; the sealing assembly can rotate around the axis of the water injection pipe 2 and move axially to selectively open and close the water permeable hole 9.

[0019] It should be noted that during use, the cap 10 on the first water inlet section 31 is pulled out, and the female connector of the water dispenser or other water supply device is inserted and sealed onto the first water inlet section 31 on the water injection pipe 2. After the connection is completed, the sealing component is rotated. The sealing component rotates along the axis of the water injection pipe 2, generating axial displacement and opening the passage between the first water inlet section 31 and the water permeable hole 9. The water flow output from the female connector then flows into the water permeable hole 9 through the first water inlet section 31 and is continuously injected into the water bag cavity until the water bag is completely filled. After filling, the sealing component is rotated in the opposite direction to reseal the water permeable hole 9, the water supply is stopped, the female connector is pulled out, and the cap is moved to the end of the first water inlet section 31. The whole process ensures reliable sealing and convenient operation, while realizing the rapid and safe water filling operation of the water bag.

[0020] In some examples, the first inlet section 31 and the second inlet section 32 are further connected in a stepped manner in the axial direction, with the stepped surface forming the abutment end. The sealing assembly includes: a spiral guide groove 5 and a rotating cap 6. The two spiral guide grooves 5 are respectively opened on the outer side of the outer wall of the connecting seat 1; two sliders are provided on the inner side of the rotating cap 6, and are movably disposed at the two spiral guide grooves 5 by means of the two sliders; a plug 7, one end of which is fixedly installed on the inner side of the rotating cap 6, the outer edge of which is tightly fitted with the second inlet section 32, and the other end of which can selectively abut against the abutment end.

[0021] It should be noted that when filling the water bag, the first water inlet section 31 first draws water and guides the water flow to the second water inlet section 32 in the axial direction. The stepped surface formed between them, which is the abutment end, serves as the stop surface of the plug 7. The operator rotates the rotating cap 6, and the two sliders inside the rotating cap 6 rotate and move synchronously along the spiral guide groove 5 on the outer wall of the connecting seat 1, causing the rotating cap 6 to rotate in a controlled manner and move axially. During this process, the plug 7 fixed inside the rotating cap 6 always fits circumferentially against the inner wall of the second water inlet section 32 and moves horizontally with the rotating cap 6. When the end face of the plug 7 leaves the abutment end, the first water inlet section 31 and the water permeable hole 9 are connected and opened. The water flows from the first water inlet section 31 through the second water inlet section 32 to the water permeable hole 9. When the end face of the plug 7 approaches and presses against the abutment end again, the passage is closed, realizing precise control and sealing of the opening and closing switching.

[0022] In some examples, furthermore, rubber gaskets are provided on the inner side of the contact end and the rotating cap 6 to enhance sealing. After the water bag is filled with water, the rotating cap 6 gradually approaches the contact end axially. The rubber gasket located inside the rotating cap 6 is first compressed and elastically deformed, and then the rubber gasket on the contact end is compressed synchronously, and the two rubber gaskets are adhered at the contact interface. When the compression reaches the predetermined stroke, the rebound force of the rubber gasket actively fills the micro gap, forming the main seal and blocking the water permeable hole 9. When it is necessary to release the seal, the rotating cap 6 retracts in the opposite direction, and the inner rubber gasket gradually unloads the pressure with the displacement. The rubber gasket at the contact end also rebounds accordingly, the adhesion interface separates, and the water permeable hole 9 is unobstructed again. In the entire opening and closing cycle, the two rubber gaskets repeatedly establish and release the seal by relying on elastic deformation and rebound, ensuring both instantaneous water stoppage and long-term reliability.

[0023] In some examples, further, each end of the two spiral guide grooves 5 is provided with a locking block 8, which is used to lock the rotating cap 6. During adjustment, the rotating cap 6 rotates and advances along the spiral trajectory of the two spiral guide grooves 5. When it rotates to the end of the spiral guide groove 5, it touches the locking block 8 at the end. The circumferential edge of the rotating cap 6 overcomes the elastic inclined surface thrust of the locking block 8 and passes over the locking block 8, thus locking the rotating cap 6. The rotating cap 6 is thus firmly held in the limit position. If water needs to be injected, simply apply torque in the opposite direction to disengage the rotating cap 6 from the locking block 8. The rotating cap 6 can then run in the opposite direction along the spiral guide groove 5 to complete the unlocking. The locking block 8 provides a definite stop, anti-loosening retention and clear positioning feedback throughout the entire opening and closing cycle, achieving a stable seal.

[0024] In some examples, a positioning disc 4 is coaxially connected to the outer side of the connecting seat 1. The diameter of the positioning disc 4 is larger than that of the connecting seat 1, and the positioning disc 4 is used to form a stop and positioning when pressed against the water bag to improve sealing reliability. The connecting seat 1 first fits against the end face of the water bag. Because the diameter of the positioning disc 4 is larger than that of the connecting seat 1, it first makes pressing contact with the end face of the water bag or its sealing gasket. The annular stop of the positioning disc 4 restricts the water bag, thereby significantly improving the sealing reliability of the joint area without adding additional fasteners and preventing the sealing gasket in the water bag from deforming and failing due to over-assembly.

[0025] After the water injection operation is completed, this device can close the water inlet 9 with a single rotation, immediately cutting off the water flow and forming a reliable seal before disassembling the female connector. This avoids the risks of hose rebound and kinking, hot water backflow and leakage caused by the traditional water pumping method of "disassembling the female connector first and then closing the valve". Therefore, it can significantly reduce water splashing and waste, prevent hot water from scalding the operator, simplify the operation steps, shorten the downtime, and improve the safety and ease of use of the overall water injection and cut-off process.
