Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a direct-insertion valve device and a burner. Background Technology

[0002] Existing burners include a direct-insertion valve and an injector tube. The direct-insertion valve is inserted into the injector tube, and the connection between the valve and the tube is open, resulting in a large injection space and insufficient injection efficiency. The injector tube opening is unprotected, allowing insects to easily crawl into the nozzle, causing blockage and affecting injection performance. Furthermore, the nozzle is prone to overheating during use, which also leads to higher valve body temperatures, shortening the lifespan of the direct-insertion valve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing burner, such as poor ejection effect and easy entry of insects into the nozzle, which leads to nozzle blockage. This utility model provides a direct-insertion valve device and a burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a direct insertion valve device, which includes an ejector tube, a nozzle, and a damper component;

[0006] The damper component includes a damper plate and an enclosure structure. The damper plate covers the opening of the ejector tube. The damper plate is provided with a nozzle hole and a damper hole. The nozzle is inserted into the nozzle hole.

[0007] The enclosure structure is fitted onto the outer periphery of the nozzle to form an ejector cavity between the nozzle and the enclosure structure. One end of the ejector cavity is connected to the damper hole, and the other end of the ejector cavity is provided with a first air inlet, which is located on the outer periphery of the nozzle.

[0008] In this design, one end of the ejector chamber is connected to a ventilation door, and the other end has a first air inlet. During use, the nozzle injects gas into the ejector tube, and the ejecting air enters the ejector chamber through the first air inlet, then passes through the ventilation door into the interior of the ejector tube. Because of the ejector chamber, which is smaller than an open space, the air inside is quickly consumed after ejection. The pressure difference inside and outside the ejector chamber accelerates the ejection air speed, improving the ejection effect. Simultaneously, the ejector chamber provides stronger airflow, and its location on the outer periphery of the nozzle allows for continuous airflow that effectively cools the nozzle, extending its lifespan. The enclosing structure also provides protection, preventing insects from crawling into the nozzle and causing blockages.

[0009] Preferably, the enclosure structure includes a first portion, the cross-sectional area of ​​which gradually decreases in the direction from near the ejector tube to away from the ejector tube.

[0010] In this design, by gradually reducing the cross-sectional area of ​​the first part in the direction away from the ejector tube box, the size of the first air inlet at the end away from the ejector tube is made smaller, resulting in a better shielding effect and better preventing insects from crawling to the nozzle and causing nozzle blockage.

[0011] Preferably, the enclosure structure further includes a second part, which is located on the side of the first part away from the ejector tube, and the second part is connected to the first part;

[0012] The cross-sectional area of ​​the second portion gradually increases in the direction from the ejector tube toward the ejector tube.

[0013] In this scheme, by setting a second part on the side of the first part away from the ejector tube and connecting the second part to the first part, the cross-sectional area of ​​the enclosure structure first decreases and then increases in the direction from near the ejector tube to away from the ejector tube, so that the shape of the enclosure structure imitates the structure of the ejector tube, which has the function of strengthening the ejection and improving the ejection effect of the direct insertion valve device.

[0014] Preferably, the damper further includes a handle, the enclosure structure is connected to the damper plate, the handle is connected to the enclosure structure, and the handle extends from the enclosure structure to the outside of the enclosure structure.

[0015] In this design, the damper also includes a handle. The enclosure structure is connected to the damper plate, and the handle is connected to the enclosure structure. When the handle is turned, it drives the enclosure structure to rotate, which in turn drives the damper plate to rotate. This allows adjustment of the overlap area between the damper opening and the ejector tube opening, thereby regulating the airflow rate. By extending the handle from the enclosure structure to the outside of the enclosure structure, it makes it easier for the user to operate the handle to adjust the airflow.

[0016] Preferably, the handle is located at the end of the enclosure structure away from the ejector tube.

[0017] In this design, by placing the handle at the end of the enclosure structure away from the ejector tube, the handle is further away from the ejector tube, resulting in a lower handle temperature and preventing burns during adjustment. It also makes it more convenient for users to perform adjustment operations.

[0018] Preferably, the enclosure structure is ring-shaped.

[0019] In this scheme, by setting the enclosure structure to be annular, the flow of gas within the enclosure structure becomes smoother, the gas flow velocity is increased, and the ejection effect and heat dissipation effect are further improved.

[0020] Preferably, the nozzle has a nozzle cavity inside, and the nozzle also has an air guide hole, which connects the nozzle cavity and the ejection cavity.

[0021] In this scheme, by setting an air duct at the nozzle to connect the nozzle cavity and the ejection cavity, ejection is added in the nozzle cavity in addition to being carried out through the ejection cavity. At the same time, the air duct can also dissipate heat from the nozzle by increasing the gas flow, further enhancing the ejection effect and heat dissipation effect.

[0022] Preferably, the air intake hole is located at the end of the ejector cavity away from the ejector tube.

[0023] In this design, by placing the air intake hole at the end of the ejector cavity away from the ejector tube, it is easier for the air intake hole to draw outside air into the ejector cavity, thereby further enhancing the ejection effect and heat dissipation effect.

[0024] This utility model also provides a burner, which includes the aforementioned direct-insertion valve device.

[0025] Preferably, the burner further includes a chassis, on which a second air inlet is provided, the second air inlet being located below the first air inlet.

[0026] In this design, by opening a second air inlet on the chassis, outside air enters the chassis through the second air inlet, then enters the ejector cavity, and finally enters the ejector tube. By placing the second air inlet below the first air inlet, it is easier for air to flow from the second air inlet to the first air inlet, and then enters the ejector tube through the ejector cavity, thereby further improving the ejection effect and heat dissipation effect.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] During operation, the nozzle injects gas into the ejector tube. The ejector air enters the ejector chamber through the first air inlet and then passes through the damper hole into the interior of the ejector tube. Due to the ejector chamber, which is smaller than an open space, the air inside is rapidly consumed after ejection. The pressure difference between the inside and outside of the ejector chamber accelerates the ejector air's speed, improving the ejection effect. Simultaneously, the ejector chamber allows for stronger airflow. Positioning the ejector chamber and the first air inlet on the outer periphery of the nozzle ensures continuous airflow, effectively cooling the nozzle and extending its lifespan. The enclosing structure also provides protection, preventing insects from crawling into the nozzle and causing blockages. Attached Figure Description

[0054] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0055] Example 1

[0056] like Figures 1-4 As shown, this embodiment provides a burner 100, which includes a direct-insertion valve device 200.

[0057] The direct-insertion valve device 200 includes an ejector tube 300, a nozzle 400, and a damper component 500. The damper component 500 includes a damper plate 510 and a protective structure 520. The damper plate 510 covers the opening of the ejector tube 300 and has a nozzle hole 511 and a damper hole 512. The nozzle 400 is inserted into the nozzle hole 511. The protective structure 520 is sleeved on the outer periphery of the nozzle 400 so that an ejector cavity 600 is formed between the nozzle 400 and the protective structure 520. One end of the ejector cavity 600 is connected to the ventilation door hole 512, and the other end of the ejector cavity 600 is provided with a first air inlet 700, which is located on the outer periphery of the nozzle 400.

[0058] During use, nozzle 400 injects gas into ejector tube 300. Ejected air enters ejector chamber 600 through first air inlet 700, and then enters the interior of ejector tube 300 through damper hole 512. Due to the smaller space of ejector chamber 600 compared to an open space, the air inside ejector chamber 600 is rapidly consumed after ejection. The pressure difference inside and outside ejector chamber 600 accelerates the ejected air speed, improving the ejection effect. Simultaneously, the airflow within ejector chamber 600 is stronger, and the placement of ejector chamber 600 and first air inlet 700 on the outer periphery of nozzle 400 allows the airflow to continuously scour nozzle 400, effectively cooling it and extending its service life. The enclosure structure 520 provides a shielding effect, preventing insects from crawling into nozzle 400 and causing blockage.

[0059] The enclosure structure 520 includes a first part 521. The cross-sectional area of ​​the first part 521 gradually decreases in the direction from near the ejector tube 300 to away from the ejector tube 300, thereby making the size of the first air inlet 700 at the end away from the ejector tube 300 smaller, resulting in a better shielding effect and better preventing insects from crawling to the nozzle 400 and causing the nozzle 400 to become clogged.

[0060] The damper assembly 500 also includes a handle 530. The enclosure structure 520 is connected to the damper plate 510, and the handle 530 is connected to the enclosure structure 520. The handle 530 extends outward from the enclosure structure 520, so that when the handle 530 is turned, it can drive the enclosure structure 520 to rotate, which in turn drives the damper plate 510 to rotate. This allows adjustment of the overlap area between the damper hole 512 and the opening of the ejector tube 300, thereby adjusting the airflow rate. By extending the handle 530 outward from the enclosure structure 520, it makes it easier for the user to operate the handle 530 to adjust the airflow.

[0061] The handle 530 is located at the end of the enclosure structure 520 away from the ejector tube 300. On the one hand, this makes the handle 530 farther away from the ejector tube 300 and the temperature of the handle 530 lower, avoiding burns during adjustment. On the other hand, it also makes it more convenient for users to perform adjustment operations.

[0062] The enclosure structure 520 is annular, which makes the gas flow more smoothly within the enclosure structure 520, increases the gas flow speed, and further enhances the ejection effect and heat dissipation effect.

[0063] In this embodiment, the enclosure structure 520 is conical. In other embodiments, other suitable shapes for the enclosure structure 520 may also be selected.

[0064] The burner 100 also includes a chassis 800, on which a second air inlet 810 is provided, located below the first air inlet 700. By providing the second air inlet 810 on the chassis 800, outside air enters the chassis 800 through the second air inlet 810, then enters the ejector chamber 600, and finally enters the ejector tube 300. By positioning the second air inlet 810 below the first air inlet 700, it facilitates air flow from the second air inlet 810 to the first air inlet 700, and then through the ejector chamber 600 into the ejector tube 300, further improving the ejection and heat dissipation effects.

[0065] Example 2

[0066] The structure of this embodiment is basically the same as that of embodiment 1, and the same structure will not be described in detail. The difference is that:

[0067] like Figure 5 and Figure 6As shown, the enclosure structure 520 also includes a second part 522, which is located on the side of the first part 521 away from the ejector tube 300 and is connected to the first part 521. The cross-sectional area of ​​the second part 522 gradually increases in the direction from near the ejector tube 300 to away from it, making the shape of the enclosure structure 520 mimic the structure of the ejector tube 300, thus enhancing the ejection effect and improving the ejection efficiency of the direct-insertion valve device 200.

[0068] The nozzle 400 has a nozzle cavity 410 inside and an air duct 420. The air duct 420 connects the nozzle cavity 410 and the ejection cavity 600. Thus, in addition to ejection through the ejection cavity 600, ejection is also added in the nozzle cavity 410. At the same time, the air duct 420 can also dissipate heat from the nozzle 400 by increasing the gas flow, further enhancing the ejection effect and heat dissipation effect.

[0069] The air intake hole 420 is located at the end of the ejector cavity 600 away from the ejector tube 300, which makes it easier for the air intake hole 420 to draw outside air into the ejector cavity 600, further enhancing the ejection effect and heat dissipation effect.
