Description

Technical Field

[0001] The utility model relates to the technical field related to fog machines, and in particular to a threaded electric fuel injector. Background Art

[0002] Fog machines, also known as cold fog machines, are widely used in pest control and high-efficiency fertilizer spraying of crops such as cotton, wheat, rice, corn, greenhouse crops, fruit trees, forests, tea gardens, etc. However, fog machines are no longer only used for pest control and fertilization in agriculture, forestry, greenhouse fruit trees, etc., but are also widely used in urban sanitation, animal husbandry, mosquito control, control of vectors such as flies and cockroaches, warehousing and logistics, grain and oil food processing plants, garbage and sewage treatment plants, large-scale disease control and epidemic prevention, and disinfection and sterilization of public places.

[0003] The fuel spraying structure of the existing smoke machine adopts an evaporation net plus a pipeline structure. The fuel in the pipeline is sprayed into the combustion chamber through the evaporation net. However, the carbon deposits from the combustion of the fuel easily clog the oil outlet, resulting in a small amount of fuel output or even complete blockage of the oil outlet, and a high failure rate. Therefore, it is necessary to design a threaded electric fuel injector. Utility Model Content

[0004] In view of the above technical problems, the purpose of the utility model is to overcome the problem in the prior art that the evaporation network plus pipeline structure is easily blocked by carbon deposits and causes failures.

[0005] In order to achieve the above object, the utility model provides a threaded electric fuel injector, comprising: a fuel injector body and a threaded mounting sleeve which is assembled on the fuel outlet of the fuel injector body and can be threadedly assembled on the combustion chamber.

[0006] Preferably, a polygonal protrusion is protrudingly provided on the outer wall of the threaded mounting sleeve.

[0007] Preferably, an oil inlet connector is mounted on the oil inlet of the fuel injector body.

[0008] Preferably, a blocking portion is protrudingly provided on the outer wall of the oil inlet connector.

[0009] Preferably, the oil inlet connector is a pagoda connector.

[0010] Preferably, the threaded mounting sleeve is made of one of copper alloy, aluminum alloy and alloy steel.

[0011] According to the above technical scheme, the utility model provides a threaded electric fuel injector, which has the following beneficial effects when in use: the use of the electric fuel injector can not only improve the spray uniformity of the fuel, but also facilitate the control of the fuel spray amount; the threaded mounting sleeve on the electric fuel injector is threadedly assembled on the combustion chamber, which is not only convenient for disassembly and cleaning, but also convenient for replacing the electric fuel injector, which is beneficial for later repair and maintenance, and regular cleaning can effectively solve the failure rate caused by blockage.

[0019] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0020] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0021] like Figure 1-3As shown, a threaded electric fuel injector comprises: a fuel injector body 1 and a threaded mounting sleeve 2 which is assembled on the fuel outlet of the fuel injector body 1 and can be threadedly assembled on the combustion chamber.

[0022] The use of an electric fuel injector installed on the combustion chamber can not only improve the uniformity of fuel spraying, but also facilitate the control of the fuel spraying amount; the threaded mounting sleeve 2 on the electric fuel injector is threadedly assembled on the combustion chamber, which is not only convenient for disassembly and cleaning, but also convenient for replacement of the electric fuel injector, which is beneficial for later repair and maintenance. Regular cleaning can effectively reduce the failure rate caused by blockage.

[0023] The fuel injector body 1 is an existing mature technology. The fuel injector body 1 is now mainly used in automobile engines. The fuel injector body 1 is mainly composed of a solenoid valve, a needle valve and a nozzle body. The solenoid valve is a key component for controlling the injection process. When the electronic fuel injection system receives a control signal, the solenoid valve will open, and then the needle valve will move upward to open the injection hole. During operation, the fuel injector will be controlled by the system voltage, and the injection time and injection amount will be controlled by different voltage signals. When the injection time becomes longer, the injection amount will increase accordingly, and vice versa.

[0024] The high temperature environment of the combustion chamber will affect the service life of the plastic parts and electronic components on the electric fuel injector. Therefore, it is assembled on the combustion chamber through threaded assembly. If it is connected by fixed welding, it will be inconvenient to replace and clean it later.

[0025] A polygonal protrusion 3 is protruded from the outer wall of the threaded mounting sleeve 2 .

[0026] The multi-angle protrusion 3 can be clamped by a wrench tool to rotate the threaded mounting sleeve 2, which is convenient for installing and disassembling the electric fuel injector.

[0027] The oil inlet of the fuel injection nozzle body 1 is equipped with an oil inlet connector 4, and the oil inlet connector 4 is connected to the oil inlet pipeline.

[0028] A blocking portion 5 is protruding from the outer wall of the oil inlet connector 4 .

[0029] When the oil inlet pipe is installed on the oil inlet connector 4 through the connector, the clamping block portion 5 is not only conducive to the rapid positioning and installation of the connector, but also can play a role in preventing it from falling off.

[0030] The oil inlet connector 4 is a pagoda connector.

[0031] When the oil inlet pipe is a hose, the oil inlet pipe can be directly sleeved on the outside of the pagoda connector.

[0032] The threaded mounting sleeve 2 is made of one of copper alloy, aluminum alloy and alloy steel.

[0033] Copper alloy, aluminum alloy and alloy steel are all high temperature resistant materials, which can increase the service life of the threaded mounting sleeve 2. The threaded mounting sleeve 2 can also be made of other common high temperature resistant materials, such as ceramics, nickel-based alloys and other materials.

[0034] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0036] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
