Description

Technical Field

[0001] The utility model relates to the technical field of daily utensils, in particular to a nozzle matching cover and a nozzle assembled therewith. Background Art

[0002] The nozzles of existing water cups or milk bottles are of the air-return type, and generally have structures such as a V-shaped one-way valve, a corrugated valve, and a through hole. For example, the technical solution disclosed in Chinese Patent CN208541061U: a splash-proof, leak-proof and breathable water cup, the cup cover body further includes an exhaust assembly, and the exhaust assembly includes an elastic exhaust link, an exhaust hose and an exhaust valve; an exhaust groove is provided on the flip cover, a link through hole is provided at the bottom of the exhaust groove, an exhaust hole is opened on the rotary cover, and the exhaust hole is directly below the link through hole; the exhaust valve is installed in the exhaust hole and is connected to the straw assembly through the exhaust hose; the elastic exhaust link is located in the link through hole, and the lower end of the elastic exhaust link is in contact and cooperation with the exhaust valve.

[0003] The above-mentioned prior art not only increases the production cost of the water cup by separately setting a valve, but also makes the nozzle structure complex and easy to damage. Therefore, a nozzle with air-return and water leakage prevention that can effectively block the reverse flow of water droplets and water flow in the air-return channel and the air-return channel will not be blocked during assembly is designed. However, when there is a negative pressure formed by hot water in the newly designed nozzle cup, it will cause the overall air-return of the nozzle to collapse towards the space area, which may deform the air-return hole and may cause the air-return function to fail. Therefore, a structure that can effectively prevent the deformation of the air-return hole needs to be designed. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a nozzle matching cover that can effectively play a supporting role and has a guiding assembly function, and a nozzle assembled therewith. To solve the above technical problems, the utility model provides the following technical solutions:

[0005] A nozzle matching cover, the matching cover is assembled on a nozzle adapted thereto, a fitting is provided on the lower surface inside the matching cover, and when the matching cover and the nozzle are in an assembled state, the fitting is inserted into a reserved channel of the nozzle and blocks the upper end opening of the reserved channel.

[0006] The shape and size of the fitting are matched with the shape and size of the corresponding nozzle, the height protruding downward is matched with the designed space depth of the nozzle, and there is a certain distance from the baffle of the nozzle. Among them, the fitting can be a cylindrical structure or a spherical structure, as long as the matching function can be realized.

[0007] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions:

[0008] The mating cover is provided with a through hole for the straw of the nozzle to extend out, and the bottom surface of the fitting is inclined downward from the side close to the through hole to the side far from the through hole. The above design has a cooling effect on the water vapor, causing the water vapor to condense into water droplets here and directly fall back into the bottle along the inclined surface, without dripping onto the baffle.

[0009] The inner bottom surface of the mating cover is a horizontal plane. The above planar design cooperates with the nozzle to achieve the effect of secondary water sealing, preventing water from seeping between the nozzle flange and the plastic part.

[0010] The outer surface of the upper part of the mating cover is also provided with a threaded outer cover, and the inner surface of the threaded outer cover is closely attached to the outer surface of the mating cover. Due to controlling the shrinkage degree in the product appearance of the mating cover, the threaded structure of this mating cover and the traditional water cup needs to be separated parts. The form of separation can be a structural cooperation such as a buckle, or secondary overmolding.

[0011] The threaded outer cover and the mating cover are mutually buckled, or the threaded outer cover and the mating cover are integrally formed by secondary overmolding.

[0012] The inside of the mating cover is provided with an internal thread.

[0013] On the other hand, the present utility model also simultaneously provides the following technical solutions:

[0014] A nozzle, the nozzle is adapted to the mating cover as described above. The nozzle is provided with a backflow mechanism, and the backflow mechanism includes a backflow channel that penetrates up and down and a backflow structure provided in the backflow channel. When the mating cover is assembled on the nozzle, the fitting of the mating cover is inserted into the backflow channel.

[0015] The inner surface of the upper part of the backflow channel is provided with a baffle protruding into the backflow channel. When the mating cover and the nozzle are in the assembled state, the lower end surface of the fitting of the mating cover does not contact the baffle.

[0016] The outer peripheral edge of the upper opening of the backflow channel is provided with an upward protruding annular rib. When the mating cover and the nozzle are in the assembled state, the annular rib abuts against the inner bottom surface of the mating cover. To achieve the effect of secondary water sealing and prevent water from seeping between the nozzle flange and the plastic part.

[0017] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0018] The design of the mating cover of the present utility model can not only prevent the deformation of the nozzle silicone rubber assembled with it and play a supporting role for the nozzle, but also play a guiding assembly role during the actual use of the product when installing the nozzle. At the same time, during the process of assembling the water cup after the mating cover and the nozzle are assembled, the assembled parts of the mating cover also play a positioning role, which can effectively prevent the torsional deformation of the entire nozzle flange.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In combination with the drawings, a nozzle mating cover provided by the present utility model and the nozzle assembled therewith will be further described.

[0029] Embodiment 1, as Figures 1-3 shown, a nozzle mating cover can be assembled with the nozzle 3.

[0030] Among them, an assembly part is provided on the inner lower surface of the mating cover 1. In this embodiment, the assembly part is a columnar structure, namely the assembly column 11.

[0031] Further, a through hole 12 for the straw 35 of the nozzle 3 to extend out is formed on the mating cover 1. The bottom surface of the assembly column 11 slopes downward from the side close to the through hole 12 to the side far from the through hole 12, forming an inclined surface 13, so as to form a cooling effect on the water vapor, causing the water vapor to condense into water droplets here and directly fall back into the assembled bottle body along the inclined surface, without dripping onto the baffle 33 of the nozzle 3.

[0032] Further, the inner bottom surface 14 of the mating cover 1 is a horizontal plane, which is mated with the nozzle 3 to achieve the effect of secondary water sealing.

[0033] Further, an internal thread 15 is provided inside the mating cover 1 for screwing and closing with the external thread of the bottle mouth of the bottle body adapted thereto.

[0034] As Figures 4-5 shown, it is a schematic diagram of the mating cover 1 and the screw-threaded outer cover 2 in a fixed state. Among them, the screw-threaded outer cover 2 is provided on the upper part of the mating cover 1, and the inner surface of the screw-threaded outer cover 2 is closely attached to the outer surface of the mating cover 1. Due to controlling the shrinkage degree in the product appearance of the mating cover 1, the mating cover 1 and the screw-threaded structure of the traditional water cup need to be separated parts.

[0035] Further, the screw-threaded outer cover 2 and the mating cover 1 are mutually buckled, or the screw-threaded outer cover 2 and the mating cover 1 are integrally formed by two-shot overmolding. It is only necessary to firmly fix the screw-threaded outer cover 2 and the mating cover 1. For example, when the buckling method is adopted, a clamping block can be provided inside the screw-threaded outer cover 2, and a clamping groove can be provided on the mating cover 1, and the mating cover 1 and the screw-threaded outer cover 2 are fixed by the form that the clamping block is clamped in the clamping groove.

[0036] As Figures 6-8 shown, it is a schematic diagram of the nozzle 3 assembled on the mating cover 1 and the screw-threaded outer cover 2. Among them, the nozzle 3 is provided with a gas return mechanism, and the gas return mechanism includes a gas return channel 31 that penetrates up and down and a gas return structure 32 provided in the gas return channel 31. When the mating cover 1 is assembled on the nozzle 3, the assembly column 11 of the mating cover 1 is inserted into the gas return channel 31 and inserted at the upper opening of the gas return channel 31.

[0037] Specifically, the gas return structure 32 can be a structure such as a silica gel film with a notch, as long as it has the gas return function.

[0038] Further, a baffle 33 protruding into the gas return channel 31 is provided on the inner surface of the upper part of the gas return channel 31. When the mating cover 1 and the nozzle 3 are in the assembled state, the lower end surface of the assembly column 11 of the mating cover 1 does not contact the baffle 33, that is, there is a certain distance between the assembly column 11 of the mating cover 1 and the baffle 33.

[0039] Further, an annular rib 34 protruding upward is provided along the outer periphery of the opening on the air return passage 31. When the mating cover 1 and the suction nozzle 3 are in the assembled state, the annular rib 34 abuts against the inner bottom surface of the mating cover 1, achieving the effect of secondary water sealing and preventing water from seeping between the suction nozzle flange and the plastic part.
