Description

Technical Field

[0001] The utility model relates to a generator, in particular to a generator with a spark plug maintenance port. Background Art

[0002] Gasoline generators are usually composed of stators, rotors, end covers and bearings. The engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the process of the working cycle. Simply put, it generates kinetic energy by burning the fuel in the cylinder, driving the piston in the engine cylinder to move back and forth, thereby driving the connecting rod connected to the piston and the crank connected to the connecting rod to make reciprocating circular motion around the center of the crankshaft to output power. The role of the spark plug in the generator is to achieve ignition, ignite the fuel gas, and thus generate energy output. For high load or high pressure situations, higher quality spark plugs are needed to ensure ignition quality and efficiency. At the same time, the service life of the spark plug will also be affected, so it is very important to maintain the spark plug.

[0003] Chinese patent document CN218030371U discloses a snap-on spark plug window cover mounting structure for a generator, comprising a window inclined downward at one end and a window cover with an outer shape adapted to the window, the window extending inward in a circumferential direction to form a mounting surface, the downwardly inclined end of the window forming a second mounting end, a first snap-in opening being provided at an end of the window away from the second mounting end, a U-shaped connecting edge being provided along the mounting surface of the window, a gap being provided between the two sides of the connecting edge and the mounting surface, guide structures being provided on both sides of the window cover between the connecting edge and the gap, the window cover being connected to the first snap-in opening via a first snap-on structure, a second snap-in opening being provided at the end of the connecting edge opposite to the first snap-in opening, and a second snap-in structure being provided between the window cover and the second snap-in opening.

In the prior art, the spark plug can be maintained by removing the window cover, but the window cover and the mounting structure of the window cover are relatively complicated, resulting in a relatively complicated manufacturing process of the mounting structure, thereby increasing the cost of the generator.

[0022] The following is further described in detail through specific implementation methods:

[0023] 1. Definition

[0024] Spark plug: An electrical device, usually composed of a metal head and a center electrode, a ring electrode and an insulator. When the generator is about to work, the mixed gas is compressed and flows into the spark plug along the combustion chamber. In the combustion chamber, the voltage between the electrodes is increased, an arc is generated, and the ignition high voltage ignites the mixed gas, forming a spark, thereby igniting the fuel.

[0025] Spark plug socket: also known as spark plug wrench, the spark plug socket is a special tool for disassembling and installing spark plugs. It is a hexagonal cylinder structure with a handle insertion hole on the cylinder.

[0026] 2. The reference numerals in the drawings of the specification include: housing 1, base 2, sealing cover 3, spark plug sleeve 4, second limiting portion 5, first limiting portion 6, blocking portion 7, operating portion 8, and protruding member 9.

[0027] The embodiment is basically as shown in the attached Figure 1-Figure 6 As shown: a generator includes a shell 1 and a base 2, the shell 1 and the base 2 are detachably connected, an engine is installed in the shell 1, the engine is installed on the base 2, and a spark plug is provided on the engine.

[0028] A maintenance port adapted to the spark plug sleeve 4 is provided at the position corresponding to the spark plug on the housing 1, and a sealing cover 3 is provided on the maintenance port, and the sealing cover 3 is detachably connected to the maintenance port. Specifically, the maintenance port is located on the top surface of the housing 1 and is a circular maintenance port adapted to the spark plug sleeve 4.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the sealing cover 3 includes limiting portions at both ends and a blocking portion 7 in the middle. The diameter of the blocking portion 7 matches the diameter of the maintenance port, and the diameter of the limiting portion is larger than the diameter of the maintenance port. The first limiting portion 6 at the lower end is an elastic limiting portion, so that the first limiting portion 6 can pass through the maintenance port. Figure 6 As shown, the surface of the first limiting portion 6 that contacts the maintenance opening is a guiding inclined surface that is inclined from the outside to the inside toward the sliding direction.

[0030] The second limiting portion 5 at the upper end of the sealing cover 3 can expose the maintenance port. The second limiting portion 5 includes a sealing portion and an operating portion 8 protruding from the sealing portion. Both operating surfaces of the operating portion 8 are provided with protruding pieces 9, which are multiple parallel protruding horizontal bars arranged on the operating surface.

[0031] The specific implementation process is as follows: In the default state, the sealing cover 3 is installed in the maintenance port. When the spark plug needs to be maintained, the sealing cover 3 can be pulled out of the maintenance port by pulling the sealing cover 3 upward through the operating part 8, and then the spark plug sleeve 4 is inserted into the housing 1 through the maintenance port for operation. Figure 2 shown.

[0032] After the maintenance is completed, the sealing cover 3 is aligned with the maintenance opening and pushed downward, and the lower limiting portion is pushed into the housing 1 to complete the sealing of the sealing cover 3 .
