All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

Examples

Referring to fig. 1-7, a novel reciprocating constant pressure valve of an electric cooker comprises:

the valve body 100, the middle part of the valve body 100 is integrally formed with a vertical upward limiting cylinder 101, and the bottom of the limiting cylinder 101 is communicated with the outside; a plurality of diversion trenches 1011 penetrating through the top and the bottom of the limiting cylinder 101 are concavely arranged on the inner wall of the limiting cylinder 101 at intervals; in this embodiment, 4 diversion trenches 1011 are arranged at intervals; when the steam pressure in the inner container of the electric cooker is high, the steam moves upwards along the diversion trench 1011;

the floating block 200 is positioned at the top of the valve body 100, a vertical downward limit column 201 is integrally formed in the middle of the floating block 200, and the limit column 201 is inserted into the limit cylinder 101 and matched with the limit cylinder in a sliding guide manner; in the embodiment, a mounting groove 2011 is formed at the bottom of the limiting post 201, and a balancing weight 2012 is fixed in the mounting groove 2011; the sliding guide cooperation of the limit column 201 and the limit cylinder 101 can avoid the locking of the slider 200 when moving up and down, and can also avoid the shaking of the slider 200 when moving. The weight 2012 can increase the weight of the slider 200 and increase the resistance of the inner container of the rice cooker when vapor leaks.

The valve cover 300 is positioned at the top of the floating block 200, the lower end of the valve cover 300 is connected with the valve body 100 in a buckling way, and a plurality of exhaust holes 301 are uniformly formed at the top of the valve cover 300. As can be seen from fig. 6, a clamping block 301 for clamping is provided on the inner wall of the valve cover 300; as can be seen from fig. 3, the top of the side wall of the valve body 100 is provided with a clamping groove 105 for clamping the clamping block.

In this embodiment, two ends of the slider 200 are respectively integrally formed with a vertical downward shielding plate 202, the lower end of the shielding plate 202 extends toward the valve body 100, and a gap is left between the inner wall of the shielding plate and the outer wall of the limiting cylinder 101. By providing the shielding plate 202, the distance of vapor flow can be increased, and the time for vapor to be discharged from the vent hole 301 can be delayed.

In addition, in the present embodiment, a mounting hole 102 is provided at an eccentric position of the valve body 100, and a water leakage silica gel pad 103 is provided at a bottom of the mounting hole 102; a connecting column 1031 is integrally formed in the middle of the water leakage silica gel pad 103, and a stop block 1032 is integrally formed after the connecting column 1031 penetrates through the mounting hole 102; the length of the connection post 1031 is larger than the thickness of the mounting hole 102, and a gap is reserved between the outer wall of the connection post 1031 and the inner wall of the mounting hole 102; the mounting hole 102 of the valve body 100 is also provided with a water leakage hole 104, and when the water leakage silica gel pad 103 is attached to the bottom of the valve body 100, the water leakage silica gel pad 103 seals the water leakage hole 104. Some steam is condensed on the valve body 100 during the process of rising to the exhaust hole 301, and then flows back to the inner container of the electric cooker through the water leakage hole 104.

When the electric cooker starts to work, the floating block 200 is tightly attached to the top of the limiting cylinder 101 under the action of self gravity and the gravity of the balancing weight 2012, and at this time, the diversion trench 1011 is in a sealed state. When the pressure in the inner container of the electric cooker is increased, the water leakage silica gel pad 103 moves upwards, the water leakage silica gel pad 103 is attached to the bottom of the valve body 100, the mounting hole 102 and the water leakage hole 104 are completely sealed, a closed loop is formed in the electric cooker at the moment, no steam overflows, no energy loss exists, and energy saving can be achieved. As the heating continues, more vapor is formed from the water in the liner. When the vapor is sufficiently large, the vapor generates a large thrust force to the slider 200 through the guide groove 1011 on the valve body 100, and the slider 200 moves upward by the thrust force. It should be noted that, when the slider 200 moves upward by a large distance, the top of the slider 200 abuts against the valve cover 300.

When the slider 200 moves upward, the slider 200 is separated from the top of the stopper cylinder 101, the top of the flow guide groove 1011 is opened, and the vapor enters between the shielding plate 202 and the stopper cylinder 101 through the flow guide groove 1011 and is then discharged from the exhaust hole 301. After discharging a part of steam, the floating block 200 is reset by gravity to continuously seal the diversion trench 1011, so that the pressure in the electric cooker is kept constant. When the pressure in the inner container of the electric rice cooker is smaller, the water leakage silica gel pad 103 is reset due to gravity, the water leakage holes 104 are not sealed, and water condensed on the valve body 100 flows back into the inner container of the electric rice cooker through the water leakage holes 104.

The foregoing descriptions of specific exemplary embodiments of the present utility model are presented for purposes of illustration and description. The exemplary embodiments were chosen and described in order to explain the specific principles of the utility model and its practical application to thereby enable one skilled in the art to make and utilize the utility model in various exemplary embodiments and with various modifications as are suited to the particular use contemplated.
