Description

Sealing assembly and bubble water machine

Technical Field

The utility model belongs to the field of sealing elements, and particularly relates to a sealing assembly and a bubble water machine.

Background

With the increasing enthusiasm of people for self-making drinks and foods, various article manufacturing equipment enter the market of users after being miniaturized.

The working principle of the bubble water machine is as follows: the valve of the carbon dioxide gas bottle is opened through the key pressing rod and the thimble of the gas inlet valve, compressed carbon dioxide gas in the gas bottle is conveyed into the gas charging connector through the gas inlet pipe, and is injected into purified water or other beverage products of the pressure-resistant bottle from a small hole at the lower end of a nozzle pipe of the gas charging connector at an increased speed, so that bubble water is prepared.

At present, the sealing part and the fixing part of the pressure-resistant bottle of the bubble water machine on the market are both installed and fixed on the whole machine body and are not detachable and cleanable parts. Compared with a sealing part which is not detachable, the inflation connector or the sub-machine which is designed to be detachable and cleaned needs to be connected to the whole machine through a buckle or a thread, a sealing gasket is arranged between the inflation connector or the sub-machine and the whole machine, and the inflation connector or the sub-machine and the whole machine are sealed through the sealing gasket; the gasket is placed over the nozzle tube by a double snap fit.

However, in practical use, the compressed carbon dioxide in the gas cylinder has higher pressure before entering the inflation joint, so that the gas cannot be completely sealed, the gas leaks from the edge of the bottom of the sealing gasket, and the two buckles of the sealing gasket are easily extruded and released, so that the sealing gasket is arched and falls off; simultaneously because the exhaust hole also sets up at the coaxial center of buckle, the exhaust hole is blockked up when the buckle drops like this, and bubble water machine can't normally exhaust, and the gas of resisting pressure bottle in the in-process of inflating can't discharge, and the pressure of resisting pressure bottle constantly rises, leads to resisting pressure bottle inflation deformation.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, a sealing assembly and a bubble water machine according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the sealing assembly of the present invention includes a holder 1 and a joint 2, and a gasket 3 interposed between the holder 1 and the joint 2. Taking the bubbling water machine as an example, the fixing seat 1 is a fixing seat 1 on the machine body of the bubbling water machine, the joint 2 is an inflation joint 2, the joint 2 is connected to the fixing seat 1 in a threaded manner and is inserted into the pressure bottle 5, and the inflation joint 2 inflates the pressure bottle 5, so that the bubbling water is produced. Instead of a screw connection, a bayonet connection can also be used.

Referring to fig. 3 and 4, specifically, the joint 2 is provided with two air paths, one for entering and one for exiting. An intake passage 21 is provided at the center of the joint 2 for pumping high-pressure gas into the pressure bottle 5. And the air outlet channel 22 is eccentrically arranged on the joint 2 and used for discharging excessive air through the pressure regulating valve, thereby preventing the pressure of the pressure resistant bottle 5 from exceeding the standard. The outlet passage 22 may be provided in two or even more.

Accordingly, a through hole 31 is formed at the center of the gasket 3, and the through hole 31 communicates with the air intake passage 21. The sealing gasket 3 is eccentrically provided with a gas passing hole 32, and the gas passing hole 32 is communicated with the gas outlet channel 22. Thereby ensuring the communication of the air passages.

In order to rotatably mount the joint 2, which causes misalignment of the gasket 3, the gasket 3 and the joint 2 are circumferentially fixed. Specifically, the center of the gasket 3 is formed with a guide boss 33, the through hole 31 penetrates the guide boss 33, the side surface of the guide boss 33 is formed with a protruding positioning rib 331, the joint 2 is formed with a guide groove 23, and the guide groove 23 is inserted by the guide boss 33 and the positioning rib 331, thereby circumferentially fixing the gasket 3 and the joint 2. Further, the guide projection 33 may be provided on the joint 2, the guide groove 23 may be provided on the gasket 3, or a plurality of eccentrically provided guide projections 33 may be provided, and circumferential fixation may be achieved.

The aperture of the air passing hole 32 of the sealing gasket 3 is larger than the aperture of the port of the air outlet channel 22; the port of the air outlet passage 22 is positioned inside the air passing hole 32 of the packing 3 as the joint 2 rotates and is mounted on the joint 2. Considering the offset direction of the sealing gasket 3 due to the rotation installation, the air passing hole 32 is a kidney-shaped hole (or a straight hole or a long round hole), and two side walls of the air passing hole 32 are overlapped with two side edges of the port of the air outlet channel 22.

In order to ensure that the sealing gasket 3 is tightly connected with the joint 2, the sealing gasket 3 is stuck on the end surface of the joint 2 through the viscose in the glue grooves 4, at least two circles of glue grooves 4 are arranged on the end surface of the joint 2 from inside to outside, each circle of glue groove 4 comprises at least two arc grooves 41, a spacing part 42 is formed between the end parts of the adjacent arc grooves 41, and a radian included angle is formed between the spacing parts 42 of the circles. Generally, the included angle of the radian is 90 degrees, so that the spacing parts 42 of the two inner arc-shaped grooves 41 are vertically distributed, and the problem of local adhesion and arching caused by the fact that the spacing parts 42 are in the same direction can be effectively solved. The glue groove 4 is not required to be designed too deep, and is generally 0.1-0.3mm, so that the use amount of glue can be reduced, and the glue can conveniently overflow the glue groove 4 to form large-area sealing with the sealing gasket 3.

In addition, if the water machine is not a bubble water machine, the inlet passage 21 and the outlet passage 22 may be interchanged, or only one of them may be provided.

The utility model also comprises a bubble water machine which comprises the sealing assembly. The sealing assembly of the utility model can be arranged on the connecting parts of other air passages and water passages besides the bubble water.
