Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a burner head of an oil stove. Background Art

[0002] The functions of oil stoves are similar to those of gas stoves. In recent years, vegetable oil fuel has been developed as a fuel source, and new fuel alternatives have been developed to further save energy. However, due to the structural design of the current oil stove burner, it is inconvenient to install the air duct. Due to the structural limitations of the burner itself, waste oil aggregates and affects the ignition needle, making the stove accessories easy to break and the service life short.

[0003] Chinese patent CN202321882462.1 discloses a side needle burner, which can avoid the problem of oil leakage at the bottom of the ignition needle, but the nozzle is in a high temperature environment for a long time, the heat dissipation is slow, and the service life of the component is reduced.

[0004] Therefore, how to provide a fuel stove burner with a simple structure, easy installation and use, and long service life of accessories is a problem that technicians in this field need to solve urgently. Utility Model Content

[0005] In view of this, the utility model provides an oil stove burner head with a simple structure, a nozzle that is not easily damaged and a long service life.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fuel stove burner head, comprising an outer shell, an inner bowl, a nozzle and an ignition needle, the bottom wall of the outer shell is a stepped platform structure, a center hole is provided on the stepped platform of the bottom wall of the outer shell, the inner bowl is fixed on the inner side of the outer shell, an ignition needle mounting hole is provided on the side wall of the inner bowl, the ignition needle is fixed in the ignition needle mounting hole, the bottom of the inner bowl is removably connected with a heat-resistant bowl, the middle part of the heat-resistant bowl is provided with a through hole for avoiding the nozzle, the nozzle passes through the center hole and the through hole and enters the inner bowl, the outer side of the bottom wall of the outer shell is removably connected with a bottom air inlet joint, the bottom air inlet joint supplies air to the outer shell and the inner bowl to provide oxygen required for fuel combustion.

[0007] The beneficial effects of the utility model are as follows: the bottom wall of the outer shell is set as a stepped structure, the purpose is to ventilate and cool the nozzle seat and the bottom of the nozzle, avoid the nozzle being in a high temperature environment for a long time, and extend the service life of the components. In addition, the bottom of the inner bowl is detachably connected with a heat-resistant bowl, so that the nozzle is not in direct contact with the inner bowl, so the heat of the inner bowl cannot be easily transferred to the nozzle, thereby extending the service life of the nozzle, and connecting the fan through the bottom air inlet connector. The bottom air inlet connector caters to the customer's usage scenario and is convenient for installation and use. The bottom air inlet connector supplies air to the outer shell and the inner bowl to provide the oxygen required for fuel combustion. The components of this product are not easy to damage, have a long service life, and are easy to install and use.

[0008] Preferably, the stepped platform structure is located on the outer side of the shell, a cold air bin is formed on the inner side of the stepped platform structure, and a nozzle seat for mounting a nozzle is connected to the bottom wall of the cold air bin.

[0009] The resulting technical effect is: compared with the traditional flat design of the bottom of the shell, this product is designed with a cold air chamber, which can air cool the bottom of the nozzle and the nozzle seat to avoid excessive damage caused by the components being in a high temperature environment for a long time.

[0010] Preferably, a plurality of air holes are provided on the bottom wall of the shell and on the peripheral side close to the center hole, the bottom air inlet connector is fixedly connected to the bottom wall of the shell and the air holes are located on the inner side of the bottom air inlet connector.

[0011] The resulting technical effect is: the wind holes are used to take in air, provide the oxygen required for fuel combustion, and ensure the smooth combustion of the fuel. The bottom air inlet joint needs to supply the air output by the fan into the interior of the outer shell and then enter the inner bowl through the wind eyes on the inner bowl. Furthermore, an oil collecting trough can be set on the low platform of the bottom wall of the outer shell to collect waste oil. The oil collecting trough is away from the wind holes, so it will not affect the air intake.

[0012] Preferably, the bottom air inlet connector is a straight cylinder or a curved cylinder structure, and the bottom air inlet connector is used to connect to an external fan.

[0013] The resulting technical effect is that both straight-tube and curved-tube bottom air inlet connectors can achieve bottom-side air inlet, catering to customer usage scenarios.

[0014] Preferably, the bottom air inlet connector is a split wire tube elbow, and the wire tube connector can be directly connected to the air outlet of an external fan.

[0015] The resulting technical effect is: the split wire tube elbow can adapt to the connection angle of the interface, the direction of the elbow can be adjusted arbitrarily as needed, and it can be directly connected to the fan interface without the need for hose transition connection, making it easy to use.

[0016] Preferably, the bottom air inlet connector is a cast iron integrated elbow and is plugged into an external fan outlet.

[0017] The resulting technical effect is: the cast iron one-piece elbow is low-cost and can be directly plugged into the external fan interface without the need for a flexible connecting pipe transition.

[0018] Preferably, the heat-resistant bowl is formed by stretching of stainless steel.

[0019] The resulting technical effect is: the heat-resistant bowl is stretched and formed by stainless steel, which has good heat-resistant properties. The temperature of the inner bowl is transferred to the nozzle as little as possible, and the heat-resistant bowl dissipates heat quickly, reducing the long-term high temperature environment of the nozzle and extending the service life of the nozzle.

[0020] Preferably, a plurality of air holes are provided on the side wall of the inner bowl, and the air holes are used to conduct the airflow inside and outside the inner bowl. The air holes are spaced apart in the circumferential direction and have an inclined angle relative to the side wall of the inner bowl.

[0021] The resulting technical effect is that multiple tuyeres can guide the air between the outer shell and the inner bowl into the inner bowl for fuel combustion. The tuyeres are not arranged perpendicular to the side wall of the inner bowl, but are inclined at a certain angle, which can increase the rotational mixing effect of air and fuel and improve combustion efficiency.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See the attached Figures 1 to 9 According to an embodiment of the utility model, a fuel stove burner includes an outer shell 1, an inner bowl 2, a nozzle 3 and an ignition needle 4. The bottom wall of the outer shell 1 is a stepped platform structure 5. A center hole is provided on the stepped platform of the bottom wall of the outer shell 1. The inner bowl 2 is fixed to the inner side of the outer shell 1. An ignition needle mounting hole is provided on the side wall of the inner bowl 2. The ignition needle 4 is fixed in the ignition needle mounting hole. The bottom of the inner bowl 2 is detachably connected (including detachable and non-detachable) with a heat-resistant bowl 6. The middle of the heat-resistant bowl 6 is provided with a through hole for avoiding the nozzle 3. The nozzle 3 passes through the center hole and the through hole and enters the inner bowl 2. The outer side of the bottom wall of the outer shell 1 is detachably connected (including but not limited to threaded connection, welding, bolt connection, etc.) with a bottom air inlet joint 7. The bottom air inlet joint 7 supplies air to the outer shell and the inner bowl to provide oxygen required for fuel combustion. A nozzle mounting seat is provided on the side wall of the bottom air inlet joint for connecting an external oil supply pipeline.

[0034] The main body of the ignition needle 4 can be inside the shell or outside the shell. When the ignition needle is installed on the inner side of the shell, an ignition needle through-hole is provided on the stepped platform on the bottom wall of the shell 1. The ignition needle 4 is fixed in the ignition needle through-hole and the ignition needle mounting hole, and the ignition needle passes through the bottom wall of the shell; the ignition needle through-hole is arranged on a stepped platform (high position) close to the side wall of the shell 10, so that the ignition needle is installed at a relatively high position to reduce the influence of waste oil on it. In addition, the stepped platform structure of this product can prevent waste oil from agglomerating near the ignition needle, thereby avoiding affecting the normal use of the ignition needle.

[0035] When the ignition needle body is outside the shell, it is necessary to open an ignition needle through hole on the side wall of the shell to form a hanging needle type burner head.

[0036] Specifically, the stepped platform structure 5 is located on the outside of the outer shell, and a cold air bin is formed on the inside of the stepped platform structure 5. A nozzle seat for installing the nozzle is connected to the bottom wall of the cold air bin. The cold air bin can cool the nozzle part and the nozzle seat part located in the bin, avoiding the components from being in a high temperature environment for a long time and extending their service life.

[0037] In other embodiments, a plurality of air holes are provided on the bottom wall of the outer shell 1 and around the center hole, the bottom air inlet connector 7 is connected to the bottom wall of the outer shell 1 (including but not limited to bolt connection, threaded connection, welding) and the air holes are located on the inner side of the bottom air inlet connector 7, and the wind blown by the fan can enter the inner bowl through the outer shell and the wind eyes on the inner bowl to ensure the smooth combustion of the fuel.

[0038] In other embodiments, the bottom air inlet connector 7 is a straight-cylindrical or curved-cylindrical structure. When the straight-cylindrical bottom air inlet connector is connected to the fan, a flexible connecting tube is required for transition. The bottom air inlet connector 7 is used to connect to an external fan, and the bottom air inlet connector facilitates user connection needs.

[0039] In some other embodiments, the bottom air inlet connector 7 is a split wire tube elbow, which specifically includes a connecting pipe portion connected to the housing and a movable head connected to the fan, the connecting pipe portion and the movable head are threadedly connected and the installation angle can be adjusted, and the movable head of the wire tube elbow is directly connected to the air outlet of the external fan. The elbow connection direction of the split wire tube elbow can be adjusted as needed.

[0040] In other embodiments, the bottom air inlet connector 7 is a cast iron one-piece elbow and is plugged into an external fan outlet. The cast iron one-piece elbow has low cost and can be connected to the outer shell using bolts.

[0041] Specifically, the heat-resistant bowl 6 is formed by stretching a stainless steel material, which reduces the heat transfer from the inner bowl to the nozzle, and can also dissipate heat faster, thereby preventing the nozzle from being in a high-temperature environment for a long time and extending the service life of the nozzle.

[0042] In some other embodiments, a plurality of air holes 21 are provided on the side wall of the inner bowl 2. The air holes 21 are used to conduct the airflow inside and outside the inner bowl. The air holes 21 are spaced apart in the circumferential direction and have an inclination angle relative to the side wall of the inner bowl. The air holes can be arranged in multiple rows. The inclination angle, size and distribution of the air holes can be adjusted according to the needs of the stove. The inner bowl in this embodiment is a stepped slope style, such as Figure 3 In addition, the style of the inner bowl can also be changed, it can be a straight slope type, refer to the attached Figure 6 , can be a large slope type, refer to the attached Figure 7 , can be a small straight slope type, refer to the attached Figure 8 , it can also be a platform without slope type, refer to the attached Fig. 9 .

[0043] A fire-emitting member 8 and a fire-collecting ring 9 are arranged on the top of the inner bowl to improve the fire-emitting effect. There are various types of fire-emitting members to choose from, such as plate type, wing type, etc.

[0044] This novel structure is simple and can reduce the temperature of the nozzle. The bottom air inlet mode is convenient for customer scenario needs. The cold air bin formed by the stepped platform structure can cool the nozzle and the nozzle seat, reduce the use of waste oil on the ignition needle, and reduce the failure rate of the ignition needle. The stainless steel heat-resistant bowl dissipates heat quickly, avoiding the high temperature time of the nozzle and extending its service life.

[0045] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
