Description

Technical Field

[0001] This utility model relates to the field of cigar moisture measurement sensor technology, and in particular to a heating mechanism for a cigar moisture measurement sensor. Background Technology

[0002] Finished cigars require appropriate humidity for proper aging, which helps them continue to mature, eliminating off-flavors, reducing harshness, and resulting in a smoother taste. However, excessive humidity can cause mold growth and hinder combustion. Therefore, properly controlling the humidity of finished cigars is a key factor in quality control. Currently, cigar manufacturers often use moisture measuring equipment to measure the moisture content of finished cigars for quality control. Specifically, the cigars to be tested are placed inside the moisture measuring equipment, and the moisture content is measured by a moisture sensor. However, changes in ambient temperature directly affect the stability of the moisture measuring sensor, leading to deviations in the measurement results. To address this issue, existing methods use a columnar heating rod inside the moisture measuring sensor to heat the sensor and maintain its temperature. However, the heating of the sensor by the columnar heating rod is not uniform, resulting in uneven thermal conductivity throughout the sensor. Furthermore, these heating rods are often high-powered and unsuitable for the low-temperature heating requirements of moisture measuring sensors. Utility Model Content

[0005] A heating mechanism for a cigar moisture measuring sensor includes a heat-conducting block with a placement cavity extending through one side. Heating resistors are fixedly connected to both sides of the heat-conducting block. A cavity cover is fixedly connected to one side of the heat-conducting block, and the cavity cover has a placement opening corresponding to the placement cavity. Two connectors are fixedly connected to one side of the cavity cover. A heat insulation plate is fixedly connected to the bottom of the heat-conducting block, and a circuit board is fixedly connected to the bottom of the heat insulation plate. A temperature sensor is threaded into the bottom of the heat-conducting block.

[0006] Furthermore, a power connector is provided at the bottom of the heat-conducting block, and the power connector is electrically connected to the circuit board.

[0007] Furthermore, the heat-conducting block has side grooves on both sides, and the heating resistor is set in the side grooves.

[0008] Further, the temperature sensor is electrically connected with the circuit board.

[0009] Further, the upper plate part of the heat conducting block is sleeved with an upper heat preservation shell, and the lower half of the heat conducting block is sleeved with a lower heat preservation shell.

[0010] Further, the bottom outer wall of the lower heat preservation shell is fixedly connected with a support frame.

[0011] Further, the bottom of the lower heat preservation shell is provided with a plurality of heat dissipation openings.

[0012] Further, the cigar moisture measuring sensor is sleeved in the placing cavity.

[0013] Further, the two connecting heads are respectively connected with a microwave sensor and an analysis sensor of the cigar moisture measuring instrument.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] 1. By setting the moisture measuring sensor in the placing cavity of the heat conducting block, the moisture measuring sensor is uniformly heated, and the stability of the measurement result of the moisture measuring sensor is ensured.
