Description

Technical Field

[0001] This utility model relates to the field of steam equipment technology, and in particular to a steam generating device. Background Technology

[0002] Steam cleaners utilize high temperatures to quickly soften oil stains and dissolve stubborn dirt, making them widely used in cleaning equipment. The steam vaporizes rapidly upon contact with the surface, preventing water residue and making it particularly suitable for cleaning water-sensitive materials such as electronic equipment and wooden floors. Existing steam cleaners typically use electric heating, generating steam through a steam generator for user use. Existing patent application CN120488206A discloses an electric steam generator with a waste heat recovery device, relating to the field of steam generator technology. It includes a main body, with a heating chamber fixedly connected to its inner side. Multiple electric heating tubes are fixedly connected to the inner side of the main body and around the heating chamber. A recovery unit is arranged on the outer side of the main body. A water inlet pipe is fixedly connected to the upper side of the main body, and a steam exhaust pipe and a gas pipeline are fixedly connected to the right side of the main body. The recovery unit includes a fixing frame fixedly connected to the outer side of the main body. This is an electric steam generator with a waste heat recovery device.

[0003] However, the above-mentioned electric steam generator has the following disadvantages: water flows directly into the heating chamber from the inlet pipe and is heated only once by multiple electric heating tubes, resulting in low heating efficiency and insufficient heating. This makes the final steam contain more water droplets, affecting the steam quality. Utility Model Content

[0004] The purpose of this invention is to provide a steam generator that provides sufficient heating, high heating efficiency, and high-quality steam.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steam generating device, comprising a device body and an end cap disposed on the device body, a heating element disposed inside the device body, the heating element circumferentially enclosing to form a first heating cavity, a second heating cavity communicating with the first heating cavity being disposed between the heating element and the device body, the end cap being provided with a water inlet pipe, the water inlet pipe forming a water inlet channel, the water inlet pipe being provided with a multi-directional water outlet structure, and the multi-directional water outlet structure of the water inlet pipe extending into the first heating cavity.

[0006] By adopting the above technical solution, when heating water, water flows in from the inlet pipe, exits from the end of the inlet pipe to all sides through the multi-directional water outlet structure, and enters the first heating chamber. Under the action of water pressure, part of the water is sprayed to the side through the multi-directional water outlet structure to the inner wall of the heating chamber. The water flows down the inner wall of the heating chamber to the bottom of the first heating chamber. During the downward flow of the water, the inner wall of the heating chamber directly heats the water, improving the heating efficiency of the water in the first heating chamber. Moreover, the steam formed by the initial heating is heated again through the second heating chamber, reducing the water droplets mixed in the steam, improving the steam quality, and achieving full heating.

[0007] A further feature of this invention is that the multi-directional water outlet structure includes a plurality of water outlet grooves formed on the water inlet pipe, the water outlet grooves being arranged at intervals on the side wall of the water inlet pipe.

[0008] By adopting the above technical solution, multiple water outlet grooves are set at the end of the water inlet pipe. The water flows out from the water outlet grooves to the surrounding areas, so that the water flow is dispersed from one stream into multiple streams and sprayed onto the inner wall of the heating body, thereby improving the heating efficiency of the water in the first heating chamber, fully heating the water, and improving the quality of the steam after the initial heating.

[0009] A further feature of this invention is that the multi-directional water outlet structure includes a plug, which is detachably installed at the end of the water inlet pipe away from the end cap.

[0010] By adopting the above technical solution, a plug can be detachably installed at the end of the water inlet pipe to prevent water from flowing straight down into the bottom of the first heating chamber. In addition, after long-term use of the equipment, scale is easily generated inside the water inlet pipe. By removing the plug, it is easy to clean the inside of the water outlet pipe and improve the service life of the equipment.

[0011] A further feature of this invention is that a connecting channel is formed between the heating element and the end cap, and the first heating cavity is connected to the second heating cavity through the connecting channel.

[0012] By adopting the above technical solution, during the heating process, steam is generated from the first heating chamber and moves towards the side closer to the end cover. The first heating chamber is continuously heated, which increases the pressure inside the chamber. The steam flows to the second heating chamber through the connecting channel, which facilitates the secondary heating of the steam.

[0013] A further feature of this invention is that the heating body has a concave portion, the end cap has an annular flow-blocking protrusion, the annular flow-blocking protrusion abuts against the heating body, and a connecting channel is formed between the concave portion and the annular flow-blocking protrusion.

[0014] By adopting the above technical solution, the top of the heating element is concave to form a concave part, and the end cover is provided with an annular baffle protrusion. When the heating element is heated, the annular baffle protrusion of the end cover abuts against the upper surface of the heating element, reducing the direct contact area between the end cover and the heating element, avoiding excessive temperature of the end cover, and at the same time ensuring that the steam flows to the second heating chamber only through the connecting channel, preventing steam from leaking from the top of the heating element to the surrounding areas into the second heating chamber, ensuring that the steam has the same heating path and is heated evenly.

[0015] A further feature of this invention is that the heating body is provided with a plurality of heating fins, the heating fins are arranged at intervals, the heating fins are disposed on the side wall of the heating body, and the ends of the heating fins extend to the upper surface of the heating body. The heating fins include inner fins and outer fins, the inner fins are disposed on the inner side wall of the heating body, and the outer fins are disposed on the outer side wall of the heating body.

[0016] By adopting the above technical solution, the spaced heating fins increase the surface area of ​​the heating body, thereby increasing the heating area and improving the heating efficiency of the heating body on the first and second heating chambers, thus reducing water droplets in the steam and improving the steam quality.

[0017] A further feature of this invention is that the device body is provided with an air outlet pipe, one end of which is connected to the second heating chamber, and the other end of which extends out of the device body. The upper opening of the air outlet pipe is located on the device body near the end cap.

[0018] By adopting the above technical solution, the steam is heated twice in the second heating chamber and then sent out of the main body of the device through the outlet pipe. Since the upper opening of the outlet pipe is close to the top of the second heating chamber in the main body of the device, the water droplets in the steam fall to the bottom of the second heating chamber under the action of gravity and are reheated during the process of the steam flowing to the outlet pipe, thereby reducing the water droplets in the steam output from the outlet pipe and improving the steam quality.

[0019] A further feature of this invention is that the second heating chamber is annular in shape, and the second heating chamber forms a heating path that is greater than 3 / 4 of a circle, with steam entering the outlet pipe along the second heating chamber.

[0020] By adopting the above technical solution, the steam has a sufficient heating path when heated in the second heating chamber, the heating time is increased, the steam is fully heated, and the steam quality is improved.

[0021] A further feature of this invention is that: a positioning protrusion is provided on the lower surface of the end cap, and a positioning groove is provided on the main body of the device corresponding to the positioning protrusion, wherein the positioning protrusion and the positioning groove are positioned and engaged.

[0022] By adopting the above technical solution, when installing the steam generator, the positioning protrusion on the lower surface of the end cover is inserted into the positioning groove, which makes positioning convenient and facilitates the installation of the end cover. At the same time, it prevents the end cover from shifting horizontally and improves the stability of the end cover installation.

[0023] A further feature of this invention is that a sealing ring is provided between the positioning protrusion and the positioning groove, and the positioning protrusion of the end cap is sealed and installed in the positioning groove by the sealing ring.

[0024] By adopting the above technical solution, when the positioning protrusion is inserted into the positioning groove, the sealing ring achieves a seal between the positioning protrusion and the positioning groove, thereby improving the sealing performance of the end cover and the main body of the device and preventing steam leakage, which would affect the normal use of the device.

[0025] In summary, this utility model has the following beneficial effects: 1. The water inlet pipe has a multi-directional water outlet structure at the end, which allows water to be discharged from the side of the water inlet pipe and sprayed onto the inner wall of the heating body, thus ensuring sufficient heating and improving heating efficiency.

[0026] 2. By adopting a connecting channel between the heating element and the end cap, water droplets in the steam can remain in the first heating chamber under the action of gravity, and the steam can flow into the second heating chamber, which has the effect of fully heating and reducing water droplets in the steam.

[0027] 3. The second heating chamber is annular in shape, and a heating path with a diameter greater than 3 / 4 of the circle is formed in the second heating chamber. This increases the heating time, achieves full heating of steam, and improves steam quality. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] A steam generating device, such as Figure 1 , 2 As shown in Figure 4, the device includes a main body 1 and an end cap 2 mounted on the main body 1. A heating element 3 is located inside the main body 1, and a heating tube is coiled inside the heating element 3. The heating tube generates heat to increase the temperature of the heating element 3. The heating element 3 circumferentially encloses a first heating cavity 4. A second heating cavity 5, communicating with the first heating cavity 4, is located between the heating element 3 and the main body 1. The end cap 2 has a water inlet pipe 21, which forms a water inlet channel. A fixing bracket is provided on the outside of the water inlet pipe 21, and the fixing bracket is fixed to the end cap 2 by screws. The water inlet pipe 21 has a multi-directional water outlet structure 6, which extends into the first heating cavity 4. During water heating, water flows in from the inlet pipe 21 and exits from the end of the inlet pipe 21 to all sides through the multi-directional water outlet structure 6, entering the first heating chamber 4. Under water pressure, part of the water is sprayed to the side through the multi-directional water outlet structure 6 to the inner wall of the heating body 3, achieving water outlet from all sides. The water flows down the inner wall of the heating body 3 to the bottom of the first heating chamber 4. During the downward flow of the water, the inner wall of the heating body 3 directly heats the water, so that the water is preheated when it falls into the bottom of the first heating chamber 4, improving the heating efficiency of the water in the first heating chamber 4. Moreover, the steam formed by the initial heating is reheated by the second heating chamber 5, reducing the water droplets mixed in the steam, improving the steam quality, and achieving full heating.

[0037] like Figure 2 , 4As shown, the multi-directional water outlet structure 6 includes water outlet channels 61 formed on the water inlet pipe 21 and plugs 62 detachably installed at the end of the water inlet pipe 21. The water outlet channels 61 are spaced apart at the lower end of the water inlet pipe 21 and have different opening directions. When the water is heated, it is sprayed from several water outlet channels 61 onto the inner wall of the heating body 3 and flows down along the inner wall of the heating body 3 for heating, so that the water flow is dispersed from one stream into multiple streams, which makes it easier to heat up and improves the heating efficiency. In addition, in this embodiment, the plugs 62 are pan head screws and the end of the water inlet pipe 21 is provided with internal screws. The plug 62 is threaded with the end of the water inlet pipe 21 to seal it, preventing water from flowing directly downwards into the bottom of the first heating chamber 4. After long-term use, scale is easily generated inside the water inlet pipe 21. By removing the plug 62, it is easy to clean the inside of the water inlet pipe 21, thus improving the service life of the equipment. In addition, as the pan head screw goes into the water inlet pipe 21, the opening of the water outlet trough 61 is reduced due to the sealing effect of the pan head screw. Users can adjust the length of the pan head screw entering the water inlet pipe 21 to adjust the size of the opening of the water outlet trough 61 and adjust the water inlet speed.

[0038] like Figure 4 , 5 As shown in Figures 6 and 7, in this embodiment, heating fins 32 are provided on both the inner and outer sidewalls of the heating body 3. The heating fins 32 include inner fins 321 located inside the heating body 3 and outer fins 322 located outside the heating body 3. The inner fins 321 increase the heating area of ​​the first heating cavity 4, and the outer fins 322 increase the heating area of ​​the second heating cavity 5, thereby improving the heating efficiency of the heating body 3. The heating fins 32 extend from the sidewall to the upper surface of the heating body, further increasing the coverage area. The upper surface of the heating body 3 is concave to form a concave portion 31, and an annular baffle is provided on the lower surface of the end cap 2. A connecting channel 7 is provided between the flow protrusion 22, the annular flow-blocking protrusion 22 and the concave portion 31 for steam to flow to the second heating chamber 5. During heating, the annular flow-blocking protrusion 22 of the end cover 2 abuts against the upper surface of the heating body 3, reducing the direct contact area between the end cover 2 and the heating body 3, and preventing the end cover 2 from overheating. In addition, when the steam flows, it is blocked by the annular flow-blocking protrusion 22, so that the steam flows to the connecting channel 7. The steam only flows to the second heating chamber 5 through the connecting channel 7, preventing the steam from leaking from the top of the heating body 3 to the surrounding areas into the second heating chamber 5, ensuring that the steam has the same heating path and is heated evenly.

[0039] like Figure 2 , 5As shown, in this embodiment, the main body 1 of the device is provided with an exhaust pipe 11. One end of the exhaust pipe 11 is connected to the second heating chamber 5, and the other end of the exhaust pipe 11 extends out of the main body 1. The upper opening of the exhaust pipe 11 is located near the end cap 2 of the main body 1. After the steam is heated twice in the second heating chamber 5, it is sent out of the main body 1 through the exhaust pipe 11. Since the upper opening of the exhaust pipe 11 is close to the top of the second heating chamber 5 in the main body 1, the water droplets in the steam fall to the bottom of the second heating chamber 5 under the action of gravity and are heated again during the process of the steam flowing to the exhaust pipe 11. This reduces the number of water droplets output by the exhaust pipe 11 and improves the steam quality. In addition, the second heating chamber is designed to be annular. The second heating chamber 5 forms a heating path greater than 3 / 4 of the circle. The steam enters the exhaust pipe 11 along the second heating chamber 5, so that the steam has a sufficient heating path when heated in the second heating chamber 5, increasing the heating time and achieving full heating of the steam, thereby improving the steam quality.

[0040] like Figure 2 , 4 As shown in Figure 5, the lower surface of the end cap 2 is provided with a positioning protrusion ring 23, and the main body 1 of the device is provided with a positioning groove 12 corresponding to the positioning protrusion ring 23. When the end cap 2 is installed, the positioning protrusion ring 23 and the positioning groove 12 are positioned and engaged, which is convenient for positioning and facilitates the installation of the end cap 2. At the same time, it prevents the end cap 2 from shifting in the horizontal direction and improves the stability of the end cap 2 installation. A sealing ring 8 is provided between the positioning protrusion ring 23 and the positioning groove 12. The positioning protrusion ring 23 of the end cap 2 is sealed and installed in the positioning groove 12 through the sealing ring 8. The sealing ring 8 achieves the sealing between the positioning protrusion ring 23 and the positioning groove 12, improves the sealing performance of the end cap 2 and the main body 1 of the device, and prevents steam leakage.

[0041] The basic working principle of this utility model is as follows: The main body 1 of the device is provided with a heating body 3, which forms a first heating chamber 4 in a circumferential manner. After the end cover 2 is closed, the water inlet pipe 21 extends into the first heating chamber 4. The end of the water inlet pipe 21 is provided with a multi-directional water outlet structure 6. When heating, the water flows through the multi-directional water outlet structure 6 and flows out to the side. Some of the water is sprayed onto the inner wall of the heating body 3. While the water flows along the inner wall of the heating body 3 towards the bottom of the first heating chamber 4, it heats up by directly contacting the heating body 3. Moreover, the water is more easily heated after being dispersed by the multi-directional water outlet structure 6, so that the water has a certain temperature when it falls into the bottom of the first heating chamber 4, thereby improving the heating efficiency, reducing water droplets in the steam, improving the steam quality, and achieving full heating.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
