Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] refer to Figures 1 to 6 A steam valve, comprising a valve body 100 and a rubber sleeve 200; The inner cavity of the valve body 100 is provided with a rubber sleeve 200; The valve body 100 has an air outlet 13 at the top and an air inlet 23 at the bottom. The rubber sleeve 200 is provided with a first vent 31 and a second vent 41. The first vent 31 is connected to the air outlet 13, and the second vent 41 is connected to the air inlet 23. The valve body 100 is made of plastic, and the rubber sleeve 200 is made of silicone.

[0016] As a result, steam flows in from the inlet 23 and then flows out from the outlet 13. Because the inner cavity of the valve body 100 is equipped with a silicone sleeve, the steam does not directly contact the inner wall of the valve body 100, but directly contacts the sleeve body 200. This causes the heat of the steam to be transferred to the sleeve body 200 first and then to the valve body 100, thereby reducing the amount of heat transferred to the valve body 100. Consequently, the temperature of the valve body 100 is lowered, improving the working condition of the valve body 100, reducing the aging or pulverization caused by long-term heating, and extending its service life.

[0017] The shape of the rubber sleeve 200 matches the inner cavity of the valve body 100; it can be understood that the inner cavity of the valve body 100 is covered with a silicone layer structure, thereby blocking the heat transfer to a certain extent.

[0018] The air outlet 13 and the air inlet 23 are staggered to prevent external debris from entering through the air outlet 13 and exiting directly through the air inlet 23.

[0019] The valve body 100 is made of PP plastic. Of course, other suitable plastics can also be used.

[0020] refer to Figure 2 and Figure 3The valve body 100 includes an upper shell 1 and a lower shell 2. The upper shell 1 is provided with an air outlet 13 and the lower shell 2 is provided with an air inlet 23. One end of the upper shell 1 is provided with a first buckle 11, which extends downward and has a first buckle hole 111. The other end of the upper shell 1 is provided with a second fastener 12, which extends downward and has a second fastening hole 121; the first fastener 11 and the second fastener 12 are arranged opposite to each other. The lower shell 2 is provided with a first protruding buckle 21 that cooperates with the first buckle hole 111; the lower shell 2 is provided with a second protruding buckle 22 that cooperates with the second buckle hole 121.

[0021] Thus, the internal space formed by the upper shell 1 and the lower shell 2 constitutes the inner cavity. The upper shell 1 and the lower shell 2 are assembled and connected by fastening or snap-fitting, which facilitates assembly and disassembly.

[0022] The width of the first loop 11 is different from that of the second loop 12; for example, the width of the first loop 11 is greater than that of the second loop 12. The outer side of the lower shell 2 is provided with a first guide groove 24 and a second guide groove 25, that is, the first guide groove 24 and the second guide groove 25 are respectively arranged on both sides of the lower shell 2. The first guide groove 24 is provided with a first protrusion 21, and the second guide groove 25 is provided with a second protrusion 22. The first guide groove 24 engages with the first buckle 11, and the second guide groove 25 engages with the second buckle 12.

[0023] Therefore, the width dimensions of the first latch 11 and the second latch 12 are different, and the width dimensions of the corresponding first guide groove 24 and the second guide groove 25 are also different, thereby achieving foolproof and ensuring the correctness of assembly.

[0024] refer to Figure 4 The rubber sleeve body 200 includes an upper rubber sleeve 3 and a lower rubber sleeve 4; The upper rubber sleeve 3 is assembled inside the upper shell 1 of the valve body 100, and the upper rubber sleeve 3 is provided with a first vent 31; The lower rubber sleeve 4 is assembled inside the lower shell 2 of the valve body 100, and the lower rubber sleeve 4 is provided with a second vent 41.

[0025] Thus, the upper rubber sleeve 3 is assembled onto the upper shell 1, and the lower rubber sleeve 4 is assembled onto the lower shell 2. Then, the upper shell 1 and the lower shell 2 are assembled together for easy assembly.

[0026] refer to Figure 4 and Figure 5 The upper rubber sleeve 3 includes a first vent 31 and a first sleeve body 32, and the first vent 31 and the first sleeve body 32 are connected. The outer side of the first vent 31 is provided with a first annular groove 311, and the inner side of the vent 13 is provided with a first flange 131 that cooperates with the first annular groove 311; the first annular groove 311 and the first flange 131 form a fastening or limiting structure to improve the stability of the assembly.

[0027] refer to Figure 5 and Figure 6 The inner side of the upper shell 1 is provided with a limiting protrusion 14, which is located below the edge of the first sleeve 32. The limiting protrusion 14 and the top wall of the upper shell 1 form a space or groove structure that can accommodate the edge of the first sleeve 32. The edge of the first sleeve 32 can be fastened or inserted into the space or groove to further fix the upper sleeve 3.

[0028] refer to Figure 4 and Figure 5 The lower rubber sleeve 4 includes a second vent 41 and a second sleeve body 42, and the second vent 41 and the second sleeve body 42 are connected. The second vent 41 has a second flange 411 on its outer side. The second flange 411 is located below the air inlet 23, thereby achieving a limiting effect.

[0029] Thus, the first set 32 ​​and the second set 42 form a space or channel for steam flow. Steam flows in from the second vent 41 and then flows out from the first vent 31.

[0030] refer to Figure 5 The upper rubber sleeve 3 also includes an inwardly inclined wall 33, which is located at the edge of the first sleeve body 32, that is, it is arranged around the first sleeve body 32. The lower sleeve 4 also includes a third flange 43, which is located at the edge of the second sleeve 42; The outer side of the inclined wall 33 abuts against the third flange 43, thereby achieving a certain degree of sealing connection between the upper rubber sleeve 3 and the lower rubber sleeve 4 through the cooperation of the inclined wall 33 and the third flange 43.

[0031] A heating humidifier includes the aforementioned steam valve. Steam generated by heating is discharged to the outside through the valve.

[0032] Of course, this steam valve can also be used in liquid heaters such as thermos flasks and rice cookers.

[0033] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
