Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an odor box. Background Art

[0002] The raw water sources required for drinking water production mainly rely on surface water, which is divided into river water, lake reservoir water, etc. Due to human activities around the water source and the existence of the upstream water system, the water source is always at risk of pollution. The conventional treatment process of water treatment plants can remove most of the pollutants in the water source. However, for some special pollutants, emergency disposal measures need to be taken. In order to more accurately take emergency disposal measures and ensure the stable and high-quality water quality of the water leaving the factory, this puts forward higher requirements for the water quality early warning ability of the raw water.

[0003] The patent document with the publication number of CN220932950U discloses a rapid odor detection device that can improve sensitivity. By continuously introducing the raw water in the water body into the odor box, and the odor box is airtight. The raw water drops in the odor box, and the odor substances in the raw water will disperse when dropping. In the airtight space, the odor of the odor substances in the raw water will not dissipate, and the concentration of the odor substances will continue to increase. The smell of the odor substances in the odor box is stronger and easier to detect. For the earthy or musty odor substances in the water body, it is difficult to detect directly by smelling. Therefore, a heater is set to heat the raw water. After heating, the earthy or musty odor substances in the raw water volatilize and are easy to smell. By performing cold odor or / and hot odor on the raw water, if the grade of the odor substances can be determined by cold odor, there is no need to perform hot odor. By determining the grade of the odor substances in the raw water through cold odor or / and hot odor, emergency measures can be taken immediately to remove the odor substances in the water body, ensuring that the odor and taste of the tap water leaving the factory are qualified and the drinking water is safe and of high quality.

[0004] Although the above-mentioned rapid odor detection device that can improve sensitivity can solve the corresponding technical problems, its odor box is an airtight box. When performing hot odor, it is necessary to open the hot water faucet to continuously drain the 50°C hot water in the heater for 5 minutes, resulting in a large amount of water vapor that will increase the air pressure inside the odor box. When the staff opens the cabinet door to smell, the water vapor will quickly discharge outward, and it is easy to cause scalding accidents. Therefore, an odor box is proposed.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1-4 , an olfactory box, comprising a sealing mechanism 1, a water passing mechanism 2 for continuously introducing external raw water into the sealing mechanism 1, and a pressure relief mechanism 3 for realizing automatic pressure relief. The water passing mechanism 2 is arranged in the inner cavity of the sealing mechanism 1, and the pressure relief mechanism 3 is arranged on the top of the sealing mechanism 1;

[0027] Among them, the pressure relief mechanism 3 includes a gas discharge cylinder 31. The gas discharge cylinder 31 is made of a transparent material, which is convenient for the staff to more intuitively understand the up and down movement of the baffle 331. A pressure relief hole 32 is formed on the surface of the gas discharge cylinder 31. A shielding member 33 is movably connected in the inner cavity of the gas discharge cylinder 31. The shielding member 33 is located below the pressure relief hole 32. An adjusting member 34 for adjusting the distance between the shielding member 33 and the sealing mechanism 1 is arranged on the top of the gas discharge cylinder 31;

[0028] Among them, the shielding member 33 includes a baffle 331. Two guide rods 332 are movably penetrated through the baffle 331. The top ends of the guide rods 332 are fixedly connected to the gas discharge cylinder 31. A spring 333 is arranged on the top of the baffle 331.

[0029] Working principle: During cold sniffing, turn on the faucet 27 on the cold water pipe 24 and close the box door 12, so that the water inlet pipe 23 and the cold water pipe 24 continuously supply raw water into the inner cavity of the sniffing box 11, and cold sniffing operation can be carried out after 1 hour; during hot sniffing, close the faucet 27 on the cold water pipe 24 and open the faucet 27 on the hot water pipe 25, so that the water inlet pipe 23 and the first conveying pipe 22 supply raw water into the heater 21 for heating. The heated raw water continuously enters the inner cavity of the sniffing box 11 through the second conveying pipe 26 and the hot water pipe 25, and hot sniffing operation can be carried out after 5 minutes; at the same time, when storing hot water in the sniffing box 11, the water vapor generates high pressure to form a thrust, causing the baffle 331 to move upward in the inner cavity of the air release cylinder 31. The baffle 331 drives the first rubber ring 3311 and the second rubber ring 3312 to move synchronously. The baffle 331 slides on the surface of the guide rod 332, and the spring 333 is compressed by force until the bottom of the baffle 331 is located above the pressure relief hole 32. At this time, the high-temperature gas can be discharged outward through the air release cylinder 31 and the pressure relief hole 32; when the air pressure in the inner cavity of the sealing mechanism 1 is maintained at a safe level, the baffle 331 loses restraint, and using the elastic force of the spring 333, the baffle 331 can be reset, thereby realizing the effect of automatic pressure relief, effectively avoiding the situation of accidental scalding of the staff when opening the box door 12, and thus helping to improve the use safety of the sniffing box; by rotating the handwheel 3421, the handwheel 3421 drives the stud 342 to rotate. Under the action of the thread, the stud 342 drives the connecting plate 343 to move upward or downward on the surface of the guide rod 332. The connecting plate 343 drives the spring 333 and the baffle 331 to move synchronously, and thus the distance between the baffle 331 and the pressure relief hole 32 can be adjusted, and the compression process of the spring 333 can be adjusted, and the pressure of automatic pressure relief can be adjusted according to the actual use requirements.

[0030] Beneficial effects: By adding a pressure relief mechanism 3 to the top of the sealing mechanism 1, when storing hot water in the sealing mechanism 1, the water vapor generates high pressure to form a thrust, causing the baffle 331 to move upward in the inner cavity of the air release cylinder 31 until the bottom of the baffle 331 is located above the pressure relief hole 32. At this time, the high-temperature gas can be discharged outward through the air release cylinder 31 and the pressure relief hole 32; when the air pressure in the inner cavity of the sealing mechanism 1 is maintained at a safe level, using the elastic force of the spring 333, the baffle 331 can be reset, thereby realizing the effect of automatic pressure relief, effectively avoiding the situation of accidental scalding of the staff when opening the box door 12, and thus helping to improve the use safety of the sniffing box.

The bottom end of the screw rod 342 penetrates into the inner cavity of the air release cylinder 31 and is rotatably connected to a connecting plate 343 through a bearing. The top of a spring 333 is fixedly connected to the bottom of the connecting plate 343. The above design, by rotating the screw rod 342, under the action of the thread, the connecting plate 343 can be driven to move downward or upward, thereby being able to adjust the compression process of the spring 333, and thus being able to adjust the pressure of automatic pressure relief according to actual usage requirements.

[0035] Further, the connecting plate 343 is slidably sleeved on the surface of the guide rod 332. The above design can play a guiding role for the connecting plate 343, enabling the connecting plate 343 to stably move along the axial direction of the screw rod 342.

[0036] Further, two springs 333 are symmetrically arranged on the top of the baffle 331. The springs 333 are arranged in one-to-one correspondence with the guide rods 332, and each spring 333 is sleeved on the surface of the corresponding guide rod 332. The above design can play a limiting role for the springs 333, enabling the reverse elastic force generated when the springs 333 are compressed to always be in the same straight line as the direction of the pressure, avoiding the skewing of the springs 333, and contributing to extending the service life of the springs 333.

The above design, the partition 15 divides the inner cavity of the smelling box 11 into two cavities, which can realize the separate placement of the heater 21 and the faucet 27, ensuring the separation of the heater 21 from the raw water, and being safe and reliable.

[0039] Further, a maintenance panel 16 is detachably mounted on the rear side of the smelling box 11 by screws. With the above design, it is convenient to remove the maintenance panel 16 subsequently to maintain and repair the water passing mechanism 2 in the inner cavity of the smelling box 11.

[0040] Further, the water passing mechanism 2 includes a heater 21 detachably mounted on the partition plate 15 by screws. The water inlet at the bottom of the heater 21 is communicated with a first delivery pipe 22. The bottom end of the first delivery pipe 22 at the water inlet is communicated with a water inlet pipe 23 through a tee pipe. One end of the water inlet pipe 23 penetrates to the outside of the smelling box 11. A cold water pipe 24 and a hot water pipe 25 are hermetically penetrated and arranged on the partition plate 15.
