Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an automatic steam generator and steam health appliance. Background Technology

[0002] With advancements in technology and increasing emphasis on healthy eating, steam-based health appliances have emerged. Utilizing steam cooking technology, they better preserve the nutrients and original flavor of ingredients, meeting modern people's demands for health and wellness. Currently, steam-based health appliances mainly consist of two parts: a steam generator and a kettle. The steam generator delivers steam to the kettle through pipes, with steam vents at the ends of the pipes to allow steam to enter the kettle and heat the food. However, this design has a significant problem: during steam delivery, liquid in the kettle can easily flow back into the pipes, affecting the normal operation of the equipment.

[0003] To address the issue of soup backflow, some manufacturers use a twisting pipe method for backflow prevention in existing technologies. However, this method is structurally complex, and the pipe is prone to breakage or detachment after repeated twisting, affecting the stability of the equipment. Other manufacturers use one-way valves in the pipes to prevent backflow. While this can prevent soup from entering the steam generator to some extent, food residue can still enter the front section of the pipe under negative pressure, leading to adhesion or blockage. Therefore, the problems of soup backflow and pipe blockage have not been fundamentally solved, limiting the practicality and user experience of steam health appliances. Utility Model Content

[0004] In order to overcome at least one of the defects described in the prior art, this application provides an automatically opening steam generator that can effectively prevent food from entering the steam pipe.

[0005] An automatic steam generator according to an embodiment of this application includes: a steam generator; a steam pipe, one end of which is provided with a steam outlet, and the other end of which is connected to the steam generator; and a check valve assembly, which includes a plurality of check valves disposed at the steam outlet. When the steam pipe outputs fluid, the fluid will drive the check valves to elastically deform outward to open the steam outlet. When external food attempts to enter the steam outlet, the check valves abut against each other to close the steam outlet.

[0006] In this automatically opening steam generator, the one-way conduction characteristic of the check plate enables the check plate to elastically deform outward when fluid is output from the steam pipe, thereby opening the steam outlet and allowing the fluid to flow out. When external food attempts to enter the steam outlet, the check plates abut against each other, preventing them from deforming inward to close the steam outlet, thus effectively preventing food from entering the steam pipe.

[0007] According to some embodiments of this application, the check sheet is arranged in an outwardly arched arc shape.

[0008] According to some embodiments of this application, the check valve assembly further includes a check valve cylinder with an exhaust port, the check valve cylinder being fixedly connected to one end of the steam pipe, the steam outlet communicating with the exhaust port, and a plurality of the check valve plates being arranged circumferentially along the exhaust port.

[0009] According to some embodiments of this application, the check valve is made of a high-temperature resistant elastic plastic.

[0010] According to some embodiments of this application, a one-way valve is also included, the output end of which is connected to the other end of the steam pipe, and the input end of which is connected to the steam generator.

[0011] According to some embodiments of this application, a plug-in valve is also included, the plug-in valve having a plug-in hole opening upwards, the plug-in hole communicating with the steam generator, the plug-in hole being used to plug into the steam pipe to form a steam passage.

[0012] According to some embodiments of this application, a control air chamber is provided at the lower end of the plug hole. The control air chamber is connected to the steam generator. A switch is provided in the control air chamber. The upper end of the switch extends into the plug hole. When the steam pipe is plugged into the plug hole, the steam pipe will push against the switch, causing the switch to connect the steam pipe to the control air chamber.

[0013] According to some embodiments of this application, the switching element includes a piston rod, a steam inlet, and an elastic element; the piston rod includes a rod portion and a head fixed to the lower end of the rod portion, the head being disposed within the control air chamber, the rod portion having the insertion hole, and the rod portion having a piston cavity opening upwards; the steam inlet is located on the periphery of the rod portion, and the piston cavity communicates with the steam inlet; the elastic element is fixed between the head and the control air chamber; when the steam pipe is inserted into the insertion hole, the steam pipe communicates with the piston cavity, synchronously pushing the piston rod downwards to make the steam inlet communicate with the control air chamber; when the steam pipe is separated from the piston rod, the elastic element will push the piston rod upwards to cut off the steam inlet from the control air chamber.

[0014] According to some embodiments of this application, a sealing element is also included, which is disposed on the inner wall of the insertion hole. When the steam pipe is inserted into the insertion hole, the sealing element will cause the outer wall of the steam pipe to form a sealed connection with the inner wall of the insertion hole.

[0015] Based on the same inventive concept, this application also proposes a steam health appliance, characterized in that it includes an automatically opening steam generator as described above.

[0016] In summary, the automatic steam generator with opening mechanism provided in this application has the following technical advantages:

[0017] By utilizing the unidirectional conduction characteristic of the check valve, when the steam pipe outputs fluid, the fluid can drive the check valve to elastically deform outward to open the steam outlet, allowing the fluid to flow out of the steam outlet. When external food attempts to enter the steam outlet, the check valves abut against each other, preventing the check valves from deforming inward to close the steam outlet, thereby effectively preventing food from entering the steam pipe.

[0030] Example 1:

[0031] See Figure 1 , Figure 2 and Figure 5This embodiment discloses an automatically opening steam generator. The automatically opening steam generator includes a steam generator 1, a steam pipe 2, and a check valve assembly 3. In this embodiment, the steam generator 1 has a steam generator 1; one end of the steam pipe 2 is provided with a steam outlet 21, and the other end of the steam pipe 2 is connected to the steam generator 1; the check valve assembly 3 includes a plurality of check valve plates 31, which are disposed at the steam outlet 21. When the steam pipe 2 outputs fluid, the fluid will drive the check valve plates 31 to elastically deform outward to open the steam outlet 21; when external food attempts to enter the steam outlet 21, the check valve plates 31 abut against each other to close the steam outlet 21. Preferably, by utilizing the unidirectional conduction characteristic of the check valve 31, when the steam pipe 2 outputs fluid outward, the fluid can drive the check valve 31 to elastically deform outward to open the steam outlet 21, allowing the fluid to flow out of the steam outlet 21. Furthermore, when external food attempts to enter the steam outlet 21, the check valves 31 abut against each other, preventing the check valves 31 from deforming inward to close the steam outlet 21, thereby effectively preventing food from entering the steam pipe 2.

[0032] Optionally, the check valve 31 may include a rotating part, a blocking part, and an abutting part. The rotating part is rotatably connected to the steam outlet 21, and the blocking part and the abutting part are both fixed to the rotating part. The blocking part extends from the rotating part towards the central axis of the steam outlet 21, and the abutting part extends from the rotating part into the steam outlet 21, abutting against the inner wall of the steam outlet 21. There is an included angle between the blocking part and the abutting part. When the steam pipe 2 outputs fluid outward, the fluid acts on the blocking part, causing the abutting part to rotate outward through the blocking part, thereby opening the steam outlet 21 and allowing the fluid to flow out of the steam outlet 21. When external food attempts to enter the steam outlet 21, the check valves 31 abut against each other, and the abutting part abuts against the inner wall of the steam outlet 21 to prevent the blocking part from rotating inward, thus sealing the steam outlet 21. In this embodiment, the fluid is steam or water.

[0033] Optionally, a plurality of check plates 31 are arranged circumferentially around the steam outlet 21. The check plates 31 extend obliquely from the side of the steam outlet 21 toward the central axis of the steam outlet 21, so that the plurality of check plates 31 form an outwardly protruding mechanism. When the steam pipe 2 outputs fluid outward, the fluid acts on the check plates 31, causing the check plates 31 to elastically deform outward to open the steam outlet 21, allowing the fluid to flow out of the steam outlet 21. When external food attempts to enter the steam outlet 21, the external food pushes the check plates 31 inward, causing the check plates 31 to abut against each other, blocking the inward deformation of the check plates 31, thereby closing the steam outlet 21 and preventing food from entering the steam pipe 2.

[0034] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the check valve 31 is arranged in an outwardly arched arc shape. Preferably, by arranging the check valve 31 in an outwardly arched arc shape, and having several check valves 31 arranged circumferentially around the steam outlet 21, when the steam pipe 2 outputs fluid, the fluid acts on the check valve 31, causing the check valve 31 to elastically deform outward to open the steam outlet 21, allowing the fluid to flow out of the steam outlet 21. When external food attempts to enter the steam outlet 21, the external food pushes the check valve 31 inward, causing the check valves 31 to come into contact with each other. Furthermore, the outwardly arched check valve 31 can deform itself under the pressure of the external food, causing adjacent check valves 31 to come into full contact, optimizing the effect of preventing the check valve 31 from deforming inward, thereby sealing the steam outlet 21 and preventing food from entering the steam pipe 2.

[0035] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the check valve assembly 3 further includes a check valve cylinder 32 with a vent hole 33. The check valve cylinder 32 is fixedly connected to one end of the steam pipe 2, and the steam outlet 21 communicates with the vent hole 33. A plurality of check valve plates 31 are arranged circumferentially along the vent hole 33. Optionally, the check valve cylinder 32 is fixedly connected to one end of the steam pipe 2 by means of insertion or sleeve, the vent hole 33 penetrates the free end of the check valve cylinder 32, and the steam outlet 21 communicates with the vent hole 33. When the steam pipe 2 outputs fluid, the fluid pushes against the check plate 31 outward through the steam outlet 21, causing the check plate 31 to elastically deform outward to open the vent 33, allowing the fluid to flow out of the vent 33. When external food attempts to enter the steam outlet 21, the external food pushes against the check plate 31 inward, causing the check plates 31 to abut against each other, thereby preventing the check plate 31 from deforming inward, thus sealing the vent 33 and preventing food from entering the steam pipe 2.

[0036] In this embodiment, the check valve 31 is made of a high-temperature resistant elastic plastic. Optionally, the high-temperature resistant elastic plastic can be one or more of thermoplastic elastomer (TPE), high-temperature resistant PC (polycarbonate), and polypropylene (PP), so that the check valve 31 has good elasticity and high-temperature resistance.

[0037] See Figure 4 and Figure 7 In this embodiment, a one-way valve 4 is also included. The output end of the one-way valve 4 is connected to the other end of the steam pipe 2, and the input end of the one-way valve 4 is connected to the steam generator 1. Preferably, by placing the one-way valve 4 between the steam pipe 2 and the steam generator 1, it is ensured that fluid can only flow from the steam generator 1 to the steam pipe 2, effectively preventing fluid from flowing back into the steam generator 1, reducing pressure fluctuations and instability factors within the steam generator 1, thereby ensuring the stable operation of the steam generator 1.

[0038] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, a plug valve 5 is also included. The plug valve 5 is provided with a plug hole 51 that opens upwards. The plug hole 51 is connected to the steam generator 1 and is used to plug into the steam pipe 2 to form a steam passage. Preferably, the steam pipe 2 is connected to the plug hole 51, so that the steam pipe 2, the plug hole 51, and the steam generator 1 form a steam passage. In this way, the fluid output from the steam generator 1 can flow into the steam pipe 2 through the plug hole 51. Furthermore, the steam pipe 2 is housed in the health pot, and the other end of the steam pipe 2 is connected to a plug connector that extends downwards from the health pot. The plug valve 5 is set on the base for placing the health pot. In this way, when the health pot is placed on the base, the plug connector is driven to plug into the plug hole 51, so that the steam pipe 2, the plug hole 51, and the steam generator 1 form a steam passage. Correspondingly, when the health pot is removed from the base, the plug connector is driven to disengage from the plug hole 51, so that the steam pipe 2 is disconnected from the plug hole 51. This optimizes the assembly and disassembly of the steam pipe 2 and the steam generator 1, making it convenient for daily use.

[0039] Example 2:

[0040] See Figure 5 , Figure 6 and Figure 7 This embodiment also discloses an automatically opening steam generator. The main difference between the automatically opening steam generator described in this embodiment and the above-mentioned automatically opening steam generator is that: a control air chamber 52 is provided at the lower end of the insertion hole 51, the control air chamber 52 is connected to the steam generator 1, a switch element 53 is provided in the control air chamber 52, the upper end of the switch element 53 extends into the insertion hole 51, and when the steam pipe 2 is inserted into the insertion hole 51, the steam pipe 2 will push against the switch element 53, causing the switch element 53 to connect the steam pipe 2 with the control air chamber 52. Preferably, the control air chamber 52 is connected to the steam generator 1, and the upper end of the switch 53 extends into the insertion hole 51. When the steam pipe 2 is inserted into the insertion hole 51, the steam pipe 2 can abut against the upper end of the switch 53 and push against the switch 53, causing the switch 53 to connect the steam pipe 2 with the control air chamber 52, so that the steam pipe, the control air chamber 52 and the steam generator 1 form a steam passage. When the steam pipe 2 leaves the insertion hole 51, the switch 53 resets, causing the steam pipe 2 to be cut off from the control air chamber 52.

[0041] See Figure 5 , Figure 6 and Figure 7In this embodiment, the switching element 53 includes a piston rod 531, a steam inlet 532, and an elastic element 533. The piston rod 531 includes a rod portion 5311 and a head 5312 fixed to the lower end of the rod portion 5311. The head 5312 is disposed within the control air chamber 52. The rod portion 5311 is provided with the insertion hole 51, and the rod portion 5311 is provided with a piston cavity opening towards the upper end. The steam inlet 532 is opened on the periphery of the rod portion 5311, and the piston cavity and the steam inlet 532 are connected. The elastic element 533 is fixed between the head 5312 and the control air chamber 52; when the steam pipe 2 is inserted into the insertion hole 51, the steam pipe 2 communicates with the piston chamber and synchronously pushes the piston rod 531 downward to make the steam inlet 532 communicate with the control air chamber 52; when the steam pipe 2 is separated from the piston rod 531, the elastic element 533 will push the piston rod 531 upward to make the steam inlet 532 cut off from the control air chamber 52. Preferably, the rod portion 5311 and the head 5312 of the piston rod 531 can be integrally formed to give the piston rod 531 sufficient strength and improve the durability of the component; optionally, when the steam pipe 2 is inserted into the insertion hole 51, the steam pipe 2 abuts against the upper end of the rod to make the steam pipe 2 communicate with the piston chamber, and simultaneously push the piston rod 531 downward, driving the steam inlet 532 to communicate with the control air chamber 52; optionally, the elastic member 533 is disposed at the lower end of the head 5312 and the inner bottom of the control air chamber 52. When the piston rod 531 moves downward between the walls, it causes the elastic element 533 to undergo compression deformation. When the steam pipe 2 separates from the piston rod 531, the elastic element 533 returns to its original shape and pushes the piston rod 531 upward, so that the upper end of the head 5312 abuts against the inner top wall of the control air chamber 52 and forms a seal, thereby causing the steam inlet 532 to be cut off from the control air chamber 52, and / or, the outer wall of the rod portion 5311 abuts against the inner wall of the insertion hole 51 and forms a seal, so that the steam inlet 532 is cut off from the control air chamber 52.

[0042] See Figure 5 , Figure 6 and Figure 7In this embodiment, a sealing element 54 is also included. The sealing element 54 is disposed on the inner wall of the insertion hole 51. When the steam pipe 2 is inserted into the insertion hole 51, the sealing element 54 will cause the outer wall of the steam pipe 2 to form a sealed connection with the inner wall of the insertion hole 51. Preferably, the sealing element 54 is nested on the inner wall of the insertion hole 51. When the steam pipe 2 is inserted into the insertion hole 51, the sealing element 54 abuts against the outer wall of the steam pipe 2 and the inner wall of the insertion hole 51, thereby causing the outer wall of the steam pipe 2 to form a sealed connection with the inner wall of the insertion hole 51.

[0043] Example 3:

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment discloses a steam health appliance. The steam health appliance includes an automatically opening steam generator as described above. Further, it also includes a health pot and a base. The one-way valve 4 and the steam pipe 2 are assembled in the health pot, and the plug valve 5 and the steam generator 1 are assembled in the base. Preferably, the check valve assembly 3 is disposed at one end of the steam pipe 2, and the one-way valve 4 is disposed at the other end of the steam pipe 2. The input end of the one-way valve 4 is provided with a plug connector. Thus, when the health pot is placed on the base, the plug connector is driven to insert into the plug hole 51. When the plug connector is inserted into the plug hole 51, the input end of the one-way valve 4 communicates with the piston chamber, and the plug connector simultaneously pushes the piston rod 531 downwards, so that the steam inlet 532 communicates with the control air chamber 52. In this way, the steam generator 1, the control air chamber 52, and the steam inlet... 532. The piston chamber, the one-way valve 4, and the steam pipe 2 form a steam passage. When the steam pipe 2 outputs steam, the steam pushes the check plate 31 outward through the steam outlet 21, causing the check plate 31 to elastically deform outward to open the vent hole 33, allowing fluid to flow out of the vent hole 33. When external food attempts to enter the steam outlet 21, the external food pushes the check plate 31 inward, causing the check plates 31 to abut against each other, thereby preventing the check plate 31 from deforming inward, thus sealing the vent hole 33 and preventing food from entering the steam pipe 2.

[0045] Furthermore, when the health pot is removed from the base, the plug is disengaged from the plug hole 51. The elastic element 533 pushes the piston rod 531 upward, causing the upper end of the head 5312 to abut against the inner top wall of the control air chamber 52 and form a seal. This causes the steam inlet 532 to be cut off from the control air chamber 52. Alternatively, the outer wall of the rod 5311 abuts against the inner wall of the plug hole 51 and forms a seal, causing the steam inlet 532 to be cut off from the control air chamber 52, preventing the steam in the control air chamber 52 from continuing to spray outward. At the same time, the one-way valve 4 prevents the steam in the steam pipe 2 from flowing back, preventing the steam in the steam pipe 2 from spraying out from the one-way valve 4. This effectively prevents steam from spraying outward after the health pot is removed from the base, improving the safety of the equipment.

It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
