Description

Technical Field

[0001] This application relates to the field of sparkling water machine technology, and in particular to a pressure safety lock device for a sparkling water machine. Background Technology

[0002] With the continuous development of technology, devices for making soft drinks (commonly known as sparkling water machines) have been widely used, allowing people to make their own soft drinks at home for convenient consumption, improving their living standards and meeting their demands for healthy eating. Sparkling water machines are devices that can generate high pressure; therefore, their use carries certain risks. If the bottle is removed while still under significant pressure, it may fly out, posing a danger to personal safety. Therefore, the purpose of this application is to address how to prevent the bottle from being opened while under high pressure.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0004] Based on this, this application provides a pressure safety lock device for a sparkling water machine to solve one of the above-mentioned technical problems.

[0005] The technical solution adopted by this application to solve its technical problem is a pneumatic safety lock device for a sparkling water machine, comprising: a water bottle lock, which can lock or unlock the water bottle by rotation; a valve body, the valve body having an internal pneumatic channel and a pneumatic chamber, the pneumatic channel being used to receive pneumatic pressure and communicate with the pneumatic chamber, the bottom of the pneumatic chamber having a sliding hole; a valve needle, the valve needle being slidably disposed on the sliding hole and passing through the valve body to restrict the rotation of the water bottle lock, the top of the valve needle having a sliding part, the sliding part being slidably disposed in the pneumatic chamber to block pneumatic pressure and being driven by pneumatic pressure to move the valve needle downward, the valve needle being sleeved with a spring; and a sealing cover, the sealing cover being installed above the pneumatic chamber to seal the pneumatic pressure inside the pneumatic chamber.

[0006] In some embodiments, a first sealing groove is provided on the outer periphery of the sliding part, and a first sealing ring is provided on the first sealing groove.

[0007] In some embodiments, a second sealing groove is provided below the sealing cover, and a second sealing ring is provided in the second sealing groove.

[0008] In some embodiments, the water bottle lock has a locking groove, and when the water bottle lock is in the locked state, the locking groove is directly below the valve needle.

[0009] In some embodiments, the bottom of the sealing cap is fixedly provided with an abutment portion, which abuts against the top of the sliding portion when there is no air pressure. The abutment portion is provided with a cross-shaped air pressure hole.

[0010] In some embodiments, the valve body is mounted above the water bottle lock by screws and the sealing cap is fixed on the valve body.

[0011] The beneficial effect of this application is that when there is a large air pressure in the water bottle, the valve needle will be driven downward by the air pressure. The downward-driven valve needle can pass through the water bottle lock, so that the water bottle lock cannot be turned in the locked state until the air pressure inside the water bottle decreases. At this time, the valve needle will be reset under the action of the spring. At this time, the water bottle lock can be turned to unlock the water bottle, which allows the user to remove the water bottle in a safe state. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-8 As shown, this application provides a pressure safety lock device for a sparkling water machine, mainly including: a water bottle lock 1, which can lock or unlock a water bottle 61 by rotation; a valve body 2, which has an internal pressure channel 21 and a pressure chamber 22, the pressure channel 21 being used to receive pressure and communicate with the pressure chamber 22, and a sliding hole 221 being provided at the bottom of the pressure chamber 22; a valve needle 3, which is slidably disposed on the sliding hole 221 and passes through the valve body 2 to restrict the rotation of the water bottle lock 1, the top of the valve needle 3 being provided with a sliding part 31, the sliding part 31 being slidably disposed in the pressure chamber 22 to block pressure and being driven by the pressure to move the valve needle 3 downward, and a spring 32 being sleeved on the valve needle 3; and a sealing cover 4, which is installed above the pressure chamber 22 to seal the pressure inside the pressure chamber 22.

[0024] Specifically, when the air pressure inside the water bottle 61 is high, the air pressure will enter the air pressure chamber 22 through the air pressure channel 21. The air pressure chamber 22 has a sliding part 31 to block the air pressure. The high air pressure can drive the air pressure chamber 22 to move. At this time, the spring 32 is compressed by the inner wall of the air pressure chamber 22 and the bottom of the sliding part 31. The valve needle 3 passes through the sliding hole 221 and is inserted into the water bottle lock 1. The water bottle lock 1 is restricted by the valve needle 3 and cannot be turned to unlock the water bottle 61. Until the air pressure inside the water bottle 61 is less than 0.3 BAR, the force of the spring 32 is greater than the force of the air pressure inside the water bottle 61 driving the sliding part 31. The spring 32 pushes the sliding part 31 up again until it contacts the abutment part 41 and stops moving upward. At this time, the valve needle 3 no longer contacts the water bottle lock 1, and the water bottle lock 1 can rotate freely.

[0025] The sparkling water machine has a water bottle air inlet base 6: the lower end is used to connect the water bottle 61, and the upper end is used to connect the air inlet pipe, pressure relief pipe, etc. This is existing technology in this field and will not be described in detail.

[0026] The water bottle air inlet base 6 is provided with a connection port 62, which is used to connect with the air inlet channel. A third sealing ring 621 is installed at the connection point. The lower part of the connection port 62 is connected to the water bottle 61, so that the air pressure of the water bottle 61 can be delivered to the air pressure channel 21.

[0027] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0028] Reference Figure 3 As shown, in order to prevent the air pressure in the air pressure chamber 22 from leaking out of the valve body 2 through the gap around the sliding part 31, a first sealing groove 311 is provided on the outer periphery of the sliding part 31, and a first sealing ring 312 is provided on the first sealing groove 311.

[0029] Specifically, in order to prevent the air pressure in the air pressure chamber 22 from leaking out of the valve body 2 through the gap of the sealing cover 4, a second sealing groove 42 is provided below the sealing cover 4, and a second sealing ring 43 is provided in the second sealing groove 42.

[0030] Reference Figure 5 As shown, the water bottle lock 1 has a locking groove 11. When the water bottle lock 1 is in the locked state of the water bottle 61, the locking groove 11 is directly below the valve needle 3. With this setting, the valve needle 3 can automatically enter the locking groove 11 under the drive of a large air pressure, so that the water bottle lock 1 cannot unlock the water bottle 61, preventing the water bottle 61 from being removed under a large air pressure and causing the water bottle 61 to fly out.

[0031] Reference Figure 6As shown, the bottom of the sealing cover 4 is fixedly provided with an abutment part 41. When no air pressure is connected, the abutment part 41 abuts against the top of the sliding part 31. The abutment part 41 is provided with a cross-shaped air pressure hole 411. The abutment part 41 can limit the maximum sliding distance of the sliding part 31 to prevent air pressure leakage. The presence of the cross-shaped air pressure hole 411 allows the air pressure to be guided to apply force to the sliding part 31 more stably to drive the valve needle 3 when air pressure is connected.

[0032] Preferably, the valve body 2 is mounted above the water bottle lock 1 by screws 5 and the sealing cap 4 is fixed on the valve body 2. The screws are used to mount the entire valve body on the water bottle air inlet base 6 and fix the sealing cap.

[0033] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
