Abstract
Description
Technical Field
[0001] The utility model relates to an anti-rotation structure of a portable gas stove fire distributor, belonging to the technical field of portable gas stoves. Background Art
[0002] Existing cassette stoves often use a threaded connection between the ignition distributor and the stove body. Due to thermal expansion and contraction, the threaded connection can easily loosen during repeated heating and cooling, leading to a poor seal and air leakage, posing a safety hazard. Furthermore, to promote their brand, companies often stamp their logos onto the ignition distributor. When the threads loosen, the ignition distributor needs to be retightened, which changes the phase of the logo compared to when it left the factory, affecting the product's aesthetics and promotional effectiveness. Utility Model Content
[0003] In order to solve the defects of the prior art, the purpose of the utility model is to provide a portable cassette stove fire distributor anti-rotation structure, which prevents the fire distributor from loosening and ensures that the phase of the fire distributor remains unchanged.
[0004] The technical solution of the utility model is: a portable cassette stove fire divider anti-rotation structure, including a positioning mechanism for fixing the air intake pipe on the stove body, the top of the air intake pipe is fixedly connected to the fire divider base, the fire divider base and the fire divider upper cover are guided and assembled by a guide mechanism, and the fire divider base is fixedly connected to the fire divider upper cover.
[0005] The positioning mechanism includes a positioning plane and a positioning fold that cooperate with each other. The positioning planes are relatively arranged on both sides of the fixed ring. The fixed ring is fixed on the outer periphery of the air intake pipe and is integrally formed with the air intake pipe. The positioning fold is relatively arranged on the inner ring of the fixed ring piece, and the fixed ring piece is fixedly connected to the furnace body.
[0006] The fixing ring piece is fixedly connected to the furnace body by screws on both sides.
[0007] The guiding mechanism includes guiding end faces a symmetrically arranged on both sides of the fire divider cover, and guiding end faces b symmetrically arranged on both sides of the fire divider base. The guiding end faces b on both sides of the fire divider base are in sliding contact with the guiding end faces a on both sides of the fire divider cover respectively, thereby realizing phase correction of the fire divider cover relative to the fire divider base.
[0008] The materials of the fire distributor base and the fire distributor cover are both stamped metal materials.
[0009] The base of the fire distributor is fixed to the upper cover of the fire distributor by riveting.
[0010] The top of the air intake pipe is fixed to the base of the ignition distributor by means of pressure riveting.
[0011] A limiting ring integrally formed with the air inlet pipe is provided at the bottom of the fixing ring, and the outer diameter of the limiting ring is larger than the outer diameter of the fixing ring and the inner diameter of the furnace body outlet.
[0012] The stamping metal material is iron, stainless steel or titanium alloy.
[0013] The beneficial effects of the utility model are as follows: the top cover of the fire distributor is connected to the base of the fire distributor by riveting, replacing the traditional threaded connection method, thus preventing loosening and air leakage, and improving the safety of the product. The positioning mechanism fixes the phase of the fire distributor top cover, preventing the top cover from rotating, thereby ensuring that the phase of the logo on the top cover remains unchanged, without affecting the aesthetics and publicity of the product.

DETAILED DESCRIPTION
[0019] The following is combined with Figure 1-4 The utility model is further described as follows:
[0020] A portable cassette stove fire starter anti-rotation structure includes a positioning mechanism for fixing an air intake pipe 4 to a stove body 5. The top of the air intake pipe 4 is fixed to the fire starter base 2 by pressure riveting. The fire starter base 2 and the fire starter cover 1 are guided and assembled by a guide mechanism to ensure that the LOGO on the fire starter cover 1 is in phase with the fire starter base 2. The fire starter base 2 and the fire starter cover 1 are riveted and fixed. The positioning mechanism includes a positioning plane 4.1 and a positioning folded edge 3.2 that cooperate with each other. The positioning plane 4.1 is relatively arranged on both sides of the fixing ring 4.2. The fixing ring 4.2 is fixed on the outer periphery of the air intake pipe 4 and is integrally formed with the air intake pipe 4. The positioning folded edge 3.2 is relatively arranged on the inner ring of the fixing ring piece 3.1. The fixing ring piece 3.1 is fixedly connected to the furnace body 5 by screws 6 on both sides to ensure that the positioning ring piece 3.1 will not rotate relative to the furnace body 5. The position of the positioning ring piece 3.1 is fixed, the position of the positioning folded edge 3.2 is also fixed, and the positioning folded edge 3.2 fits with the positioning plane 4.1, so that the fixing ring 4.2 and the air intake pipe 4 are fixed and cannot rotate. The ignition divider base 2 riveted to the air intake pipe 4 cannot rotate and is phase-fixed. The ignition divider upper cover 1 riveted to the ignition divider upper cover 1 is phase-fixed. The phase of the LOGO on the ignition divider upper cover 1 will not change relative to the furnace body 5, and at the same time, the burner head is prevented from rotating and loosening, thereby avoiding the safety hazards caused thereby.
[0021] Specifically, the guiding mechanism includes guiding end faces a1.1 symmetrically arranged on both sides of the fire divider cover 1, and guiding end faces b2.1 symmetrically arranged on both sides of the fire divider base 2. The guiding end faces b2.1 on both sides of the fire divider base 2 are in sliding contact with the guiding end faces a1.1 on both sides of the fire divider cover 1 respectively, thereby realizing phase correction of the fire divider cover 1 relative to the fire divider base 2.
[0022] The materials of the fire distributor base 2 and the fire distributor cover 1 are both stamped metal iron. Iron has good high temperature resistance and a high melting point and is not easy to melt, ensuring the stability of the fire distributor base 2 and the fire distributor cover 1 in use.
[0023] A stop ring 4.3 is integrally formed with the air inlet pipe 4 at the bottom of the retaining ring 4.2. The outer diameter of the stop ring 4.3 is larger than both the outer diameter of the retaining ring 4.2 and the inner diameter of the outlet of the furnace body 5. The stop ring 4.3 ensures that the length of the air inlet pipe 4 entering the outlet of the furnace body 5 is constant and prevents overtravel, thus ensuring product consistency.
[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
