Description

Technical Field

[0001] This utility model relates to the technical field of liquor testing devices, specifically a liquor alcohol content testing device. Background Technology

[0002] Baijiu (Chinese white liquor) is a distilled spirit made primarily from grains, using daqu (large koji), xiaoqu (small koji), bran koji, enzymes, and yeast as saccharification and fermentation agents. The process involves cooking, saccharification, fermentation, distillation, aging, and blending. The alcohol content (ABV) of baijiu primarily reflects the volume percentage of ethanol in the liquor and is a standard indicator for measuring alcohol content. Different ABVs significantly affect the taste, processing, and drinking experience. Low-ABV baijiu (below 38% vol): smooth and sweet on the palate, with less irritation, suitable for those unaccustomed to strong spirits; High-ABV baijiu (above 52% vol): strong and full-bodied, rich in aromatic compounds, but more irritating, requiring moderate consumption. Therefore, alcohol content testing devices are needed to measure the alcohol content of baijiu (Chinese liquor) during the production process. For ease of testing, handheld baijiu alcohol content testing devices are commonly used. Their main structure includes a housing, a sampling tube fixedly connected to the front of the housing, and a sealed testing chamber inside the housing. The outlet of the sampling tube is connected to the inlet of the testing chamber via a water pump. The testing chamber is equipped with a discharge mechanism and a detection probe. The housing has a controller, control switch, and display screen. During use, the internal water pump draws baijiu into the testing chamber for alcohol testing, and the reading is then directly displayed on the housing. However, existing handheld baijiu alcohol content testing devices typically lack a cleaning mechanism. After the baijiu is drawn into the testing chamber and discharged, baijiu residue can easily remain inside, affecting the accuracy of subsequent tests. Furthermore, debris can easily adhere to the inside of the testing chamber, contaminating the baijiu being tested. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 This utility model includes a detector body 1, which includes a detector housing 101. A sampling tube 102 is fixedly connected to the front side of the detector housing 101. A closed detection chamber is provided inside the detector housing 101. The outlet of the sampling tube 102 is connected to the inlet of the detection chamber through a first water pump. The detection chamber is equipped with a discharge mechanism and a detection probe. A rinsing mechanism 2 and a drying assembly 3 are provided on the detector housing 101. The rinsing mechanism 2 includes a water tank 201 and a rinsing pump. A rinsing device is fixedly provided on the detector housing 101 for rinsing. A first water outlet pipe 202 is fixedly installed on the outer wall of the sampling tube 102. A second water outlet pipe for rinsing the inside of the detection chamber is fixedly installed inside the detector housing 101. The inlet ends of the first and second water outlet pipes are connected to the outlet end of the rinsing pump through connecting pipes. The inlet end of the rinsing pump is connected to the water tank 201, which is equipped with a water replenishment mechanism. The drying assembly 3 includes an air chamber 301, which is fixedly installed inside the detector housing 101. A mounting bracket 308 is fixedly connected to the inner wall of the air chamber 301. An electric fan 307 is mounted on the side of 308. The air chamber 301 has a first air chamber sidewall and a second air chamber sidewall 306 arranged opposite to each other. The first air chamber sidewall has an air inlet 309 connecting to the outside of the detector housing 101. The first air chamber sidewall is generally located near the outer wall of the detector housing 101 (in some embodiments, the two can be designed as an integral structure). An air guide duct 305 is fixedly connected to the outside of the second air chamber sidewall 306, and the air inlet of the air guide duct 305 is located on the inner wall of the second air chamber sidewall 306. The electric fan 307... 7 is used to guide air from the air inlet 309 to the air inlet of the air duct 305. A heating element 303 is installed in the air duct between the air inlet 309 and the air inlet of the air duct 305 in the air chamber 301. A first air outlet pipe 302 for blowing the outer wall of the sampling tube 102 is fixedly installed on the detector housing 101. A second air outlet pipe for blowing the inside of the detection chamber is fixedly installed inside the detector housing 101. The air inlet ends of the first and second air outlet pipes are connected to the air outlet of the air duct 305 via connecting pipes. Multiple first water outlet pipes 202 can generally be spaced apart on the outer periphery of the sampling tube 102, and multiple first air outlet pipes 302 can also generally be spaced apart on the outer periphery of the sampling tube 102.

[0019] It is understood that the main body 1 of the detector of this utility model can be implemented with reference to the prior art, and it generally includes at least a controller, a control switch 104 and a display screen. The controller is used to output the data measured by the detection probe to the display screen. The control switch 104 is used to control electrical equipment such as the first water pump. For ease of operation, a handle 103 is generally fixedly connected to the detector housing 101.

[0020] The testing chamber is a closed structure, meaning it has no openings other than its necessary sample inlet and outlet. The outlet mechanism can be implemented with reference to existing technology, and can be manual or automatic. For example, a plugged outlet can be directly installed on the testing chamber; after removing the plug, the wine sample can be manually discharged using gravity. In some embodiments, the plugged outlet can also be located on the outlet pipe connected to the testing chamber. For ease of implementation, in some preferred embodiments, this invention preferably uses automatic outlet, with the outlet mechanism including an outlet pipe and a second water pump. The inlet of the outlet pipe is connected to the outlet of the testing chamber via the second water pump. The heating component 303 can be located anywhere between the air inlet 309 and the air inlet of the air duct 305, as long as the air introduced by the electric fan 307 from the air inlet 309 is heated by the heating component 303 before being guided to the air inlet of the air duct 305.

[0021] When using the equipment, the water tank 201 is pre-filled with distilled water. The operator holds the handle 103 and inserts the sampling tube 102 into the liquor. The equipment is started by controlling the switch 104. The first water pump inside the main body 1 of the detector runs and draws the liquor into the detection chamber inside the main body 1 of the detector through the sampling tube 102 for alcohol content testing. The test results are displayed on the screen. After the test is completed, the liquor inside the detection chamber is discharged by the second water pump inside the detection chamber. The flushing pump runs and draws out the distilled water inside the water tank 201. The distilled water is transported to the second water outlet pipe and the first water outlet pipe 202 through the connecting pipe. The distilled water is sprayed into the detection chamber through the second water outlet pipe and discharged along the sampling tube 102 to clean the inside of the detection chamber and the sampling tube 102. Distilled water is sprayed out through the first water outlet pipe 202 to clean the outer surface of the sampling tube 102 to remove liquor and impurities. Then the drying component 3 is started to dry the detection chamber and the sampling tube 102. Understandably, depending on the specific structure of the sampling mechanism, during the cleaning process, while distilled water is sprayed into the detection chamber through the second outlet pipe and discharged along the sampling tube 102, distilled water may also be discharged from the sampling tube simultaneously. However, this should not affect the cleaning of the inside of the sampling tube 102. Since whether the sampling tube is cleaned does not directly affect the test results, in some schemes, the sampling tube can be pre-closed (simply by adding a plug or valve to the sampling tube), so that during the cleaning process, the distilled water in the detection chamber is continuously discharged only along the sampling tube 102. After cleaning is completed, the distilled water inside the detection chamber can be discharged normally using the sampling tube.

[0022] It is understandable that the water replenishment mechanism can be implemented in various ways. For example, a water inlet with a sealed cap can be directly installed on the water tank 1. After removing the cap, the main body of the detector 1 can be directly used for water replenishment. For ease of use, a preferred solution is that the water replenishment mechanism includes a splicing base 204 fixedly connected to the water tank 1. The splicing base 204 has a water tank inlet / outlet hole in the middle that connects to the inner cavity of the water tank 1. A splicing connector 203 is fixedly connected to the detector housing 101. A flushing pump is fixedly installed inside the splicing connector 203. The splicing base 204 and the splicing connector 203 are detachably and fixedly connected, allowing the inlet of the flushing pump to be connected to the water tank 201 through the water tank inlet / outlet hole (generally, the inlet pipe of the flushing pump is simply passed through the water tank inlet / outlet hole). With this solution, the water tank 201 can be removed separately and replenished using the water tank inlet / outlet hole. After filling with water, the water tank 201 can be reinstalled.

[0023] There are several ways to detachably fix the splicing base 204 and the splicing joint 203. For example, it can be achieved by directly using a threaded connection structure (that is, the inner or outer wall of the water tank inlet and outlet is set with a threaded structure, and the splicing joint 203 is also set with a matching threaded structure); or it can be achieved by various snap-fit ​​connection structures. To facilitate rapid assembly, this utility model provides the following preferred embodiment: the outer peripheral wall of the splice joint 203 and the inner peripheral wall of the water tank inlet / outlet hole form a sliding fit, so that the splice joint 203 and the splicing seat 204 can move relative to each other along the axial direction of the water tank inlet / outlet hole; the inner wall of the water tank inlet / outlet hole is provided with a stepped surface that aligns with the outer end face of the splice joint 203; the outer peripheral surface of the splice joint 203 is provided with an annular groove 2031; the splicing seat 204 is provided with a radial movable groove 2045 on the side wall of the water tank inlet / outlet hole corresponding to the annular groove 2031; a limiting ball 2041 is movably disposed inside the radial movable groove 2045; and the two ends of the radial movable groove 2045 are provided with limiting flanges to prevent the limiting ball 2041 from dislodging; a limiting sleeve 2042 is slidably fitted on the outer peripheral wall of the splicing seat 204; the inner surface of the limiting sleeve 2042... An annular cavity 2043 is provided in the peripheral wall. An installation ring 2046 is fixedly sleeved on the outer peripheral surface of the splicing base 204. The installation ring 2046 is located in the annular cavity 2043. A return spring 2047 is fixedly connected between the end of the installation ring 2046 near the outer end face of the splicing base 204 and the end wall of the annular cavity 2043. The axis of the return spring 2047 is consistent with the axis of the limiting sleeve 2042. When the return spring 2047 is in its natural state, the inner peripheral wall of the limiting sleeve 2042 is located at the position of the radial movable groove 2045, so that the limiting ball 2041 and the annular groove 2031 are engaged. When the limiting sleeve 2042 is pushed to move away from the outer end face of the splicing base 204, the outer end of the radial movable groove 2045 is exposed, thereby allowing the limiting ball 2041 to disengage from the annular groove 2031. When installing the water tank 201, push the limiting sleeve 2042 away from the outer end face of the splicing base 204, separating the limiting sleeve 2042 from the area where the limiting ball 2041 is located. Then, place the splicing base 204 onto the splicing joint 203. The return spring 2047 pushes the limiting sleeve 2042 back to its original position, causing the inner wall of the limiting sleeve 2042 to push the limiting ball 2041 into the annular groove 2031, thus fixing the splicing base 204 onto the splicing joint 203. When it is necessary to remove the water tank 201, first push the limiting sleeve 2042 away from the outer end face of the splicing base 204, then pull the splicing base 204 in the direction in which the water tank 201 is removed, causing the limiting ball 2041 to move outwards, thereby separating the splicing base 204 from the splicing joint 203.

[0024] To ensure a simple and reliable structure, the return spring 2047 and the limiting sleeve 2042 are coaxially arranged (i.e., the return spring 2047 is sleeved on the outer periphery of the splicing base 204). In some alternative embodiments, the return spring 2047 may also be arranged at intervals along the circumference of the limiting sleeve 2042.

[0025] To make the structure more reliable, multiple limit balls 2041 are arranged at circumferential intervals along the splicing seat 204.

[0026] For ease of assembly, the inner wall of the outer end of the water tank inlet and outlet is provided with a third arc angle 2044, the outer wall of the top of the splice 203 is provided with a first arc angle 2032, and the two sides of the annular groove 2031 are provided with a second arc angle 2033.

[0027] The water tank 201 can be installed in a suitable position on the detector housing 101 according to the actual situation. Generally, it can be installed on the rear, top, or bottom side of the detector housing 101. To improve the sealing performance and reduce the risk of water leakage at the mating surface, a water-stop sealing ring can preferably be installed between the stepped surface of the inner wall of the water tank inlet and outlet and the outer end face of the joint 203.

[0028] To protect the internal components, in some preferred embodiments, a filter screen is installed on the side wall of the first air chamber at the location corresponding to the air inlet 309. The filter screen can be used to prevent impurities in the air from entering the interior of the air chamber 301.

[0029] To improve hot air transfer efficiency, the inner wall of the second air chamber sidewall 306 is a conical surface, and the air inlet of the air guide duct 305 is located at the center of the conical surface. Typically, the entire second air chamber sidewall 306 can be designed as a conical plate, and the conical surface facilitates the accumulation of hot air at the air inlet of the air guide duct 305. For convenient pipeline control, an electrically controlled shut-off valve 304 is preferably installed on the air guide duct 305.

[0030] In the preferred embodiment shown in the attached figure, the water tank 201 is installed on the top of the detector housing 101, and its overall working principle is as follows: Pushing the limiting sleeve 2042 upwards causes it to move away from the limiting ball 2041; pushing the splicing seat 204 upwards causes the limiting ball 2041 to move along the annular groove 2031 to the outside of the limiting sleeve 2042, thus separating the splicing seat 204 from the splicing joint 203; cleaning the water tank 201 and filling it with distilled water; pushing the limiting sleeve 2042 upwards causes it to separate from the limiting ball 2041. Separate 2041, place the splicing seat 204 onto the splicing joint 203, loosen the limiting sleeve 2042, and when the return spring 2047 pushes the limiting sleeve 2042 downward, the limiting sleeve 2042 pushes the limiting ball 2041 into the annular groove 2031, fixing the splicing seat 204 onto the splicing joint 203; the operator holds the handle 103 and inserts the sampling tube 102 into the liquor, controls the equipment to start through the control switch 104, the first water pump inside the main body of the detector 1 runs, and draws the liquor into the detector through the sampling tube 102. The alcohol content is measured in the detection chamber inside the main body 1 of the instrument, and the result is displayed on the screen. After the test is completed, the alcohol in the detection chamber is discharged by the second water pump inside the main body 1. The flushing pump operates to extract distilled water from the water tank 201 and delivers it to the second water outlet pipe and the first water outlet pipe 202 through the connecting pipe. The distilled water is sprayed into the detection chamber through the second water outlet pipe and discharged along the sampling pipe 102 to clean the inside of the detection chamber and the sampling pipe 102. Distilled water is then sprayed out through the first water outlet pipe 202 to clean the inside of the detection chamber and the sampling pipe 102. The outer surface of the sampling tube 102 is cleaned to remove liquor and impurities. Then, after draining the distilled water in the testing chamber using the conventional liquor draining method, the electric fan 307 is started to blow air onto the heating component 303. The heating component 303 heats the air, and the hot air is delivered to the first air outlet 302 and the second air outlet through the air guide duct 305 and the connecting pipe. The hot air blows air onto the outer wall of the sampling tube 102, the testing chamber, and the inner wall of the sampling tube 102 to accelerate the evaporation of moisture and keep the equipment dry for the next liquor alcohol content test.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
