Description

Technical Field

[0001] This utility model relates to the field of intelligent detection equipment technology, and in particular to a temperature and humidity detection device. Background Technology

[0002] Temperature and humidity detection devices are commonly used in daily life. They continuously monitor changes in temperature and humidity in the environment, providing convenience for people's lives and thus have been widely applied. For example, a smart humidification hardware device disclosed in patent number CN201611072166.X includes a shell, a humidity sensor, a water tank, a water inlet, a water inlet pipe, and a misting device. The water tank is located at the bottom of the shell, the water inlet is connected to the water inlet pipe, and the humidity sensor is located at the top of the shell. In this device, the detection end of the humidity sensor is placed in the external environment, or connected to the external environment through a channel in the shell, to ensure the real-time nature and accuracy of the detection data.

[0003] However, exposing the sensor to an open environment allows suspended dust particles to easily enter the housing of the temperature and humidity detection device, leading to dust accumulation and adhesion to the sensor's detection end. This not only hinders sufficient contact between the sensor and the environmental medium but also affects the accuracy of the sensor's response to temperature and humidity. Therefore, a temperature and humidity detection device that can solve the above problems is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a temperature and humidity detection device that can effectively solve the aforementioned problems.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] A preferred embodiment of this utility model provides a temperature and humidity detection device, such as... Figures 1-4 As shown, it includes a housing 1, a control circuit board 2 disposed inside the housing 1, and a temperature and humidity sensor 20 disposed on and electrically connected to the control circuit board 2; the housing 1 is provided with a first through hole 10 for the detection end of the temperature and humidity sensor 20 to be exposed; the upper surface of the dustproof plate 3 is in close contact with the inner wall of the housing 1, and there is a height difference between the lower surface of the dustproof plate 3 and the detection end of the temperature and humidity sensor 20.

[0028] A dustproof plate 3 is provided between the first through hole 10 and the detection end of the temperature and humidity sensor 20. The dustproof plate 3 is slidably disposed on the inner wall of the housing 1. A humidifying box 4 is also slidably disposed inside the housing 1 in the same direction as the dustproof plate 3. The humidifying box 4 is fixedly connected to the dustproof plate 3. A spray nozzle 40 is provided on the humidifying box 4. An opening 11 is provided on the housing 1 for the dustproof plate 3 and the humidifying box 4 to pass through. When slid into place, the spray nozzle 40 is located outside the housing 1.

[0029] The dustproof plate 3 prevents dust from the external environment from entering the housing 1 and falling onto the detection end of the temperature and humidity sensor 20, effectively preventing dust accumulation on the sensor detection end and ensuring the timeliness and accuracy of the sensor detection end's response to temperature and humidity.

[0030] In this embodiment, the dustproof plate 3 has a mounting part 30 and dustproof strips 31; the mounting part 30 is fixedly connected to the upper surface of the humidifier box 4; the dustproof strips 31 are arranged along the sliding direction of the humidifier box 4, and the dustproof strips 31 are located above the temperature and humidity sensor 20; there are multiple dustproof strips 31 arranged sequentially from top to bottom on one side wall of the mounting part 30 facing the temperature and humidity sensor 20. Air passes through the gap between two dustproof strips 31 and comes into contact with the detection end of the temperature and humidity sensor 20. As long as the detection end of the temperature and humidity sensor 20 comes into contact with the air, it can detect the temperature and humidity of the air. The arrangement of multiple dustproof strips 31 not only prevents dust particles floating in the air from accumulating at the sensor detection end, but also allows air to smoothly enter the interior of the housing 1, which has good practicality.

[0031] In this embodiment, a dust collection box 5 is provided below the connection between the dustproof strip 31 and the mounting part 30. The upper surface of the dust collection box 5 is open, and bristles 50 are vertically arranged on the upper surface of the dust collection box 5 near the opening 11. There are multiple bristles 50, and the upper ends of the multiple bristles 50 are all located in the gap between two adjacent dustproof strips 31. When the humidity in the air is insufficient and humidification is required, the operator can pull the humidification box 4 out of the housing 1 to allow the spray nozzle 40 to spray, achieving the humidification effect. During the process of pulling out the humidification box 4, the gap between the dustproof strips 31 is swept by the bristles 50, and the swept dust falls into the dust collection box 5. The action of pulling out the humidification box 4 in one go can achieve the humidification effect and remove the dust on the dustproof plate 3, avoiding excessive accumulation of dust particles on the dustproof plate 3 that would cause poor air circulation. It also eliminates the need for extra operations to clean the dustproof plate 3, making it convenient and quick to use.

[0032] In this embodiment, a baffle 32 extends horizontally from the mounting part 30 toward the ash collection box 5. The ash collection box 5 is provided with a movable hole 51 through which the baffle 32 passes, and the baffle 32 is slidably disposed within the movable hole 51. Figure 3 As shown, when the humidifier box 4 is located inside the housing 1, the baffle 32 completely covers the opening 11 of the dust collection box 5 to prevent dust in the dust collection box 5 from spilling out and to keep the inside of the housing 1 clean and tidy.

[0033] In this embodiment, the humidifier box 4 is provided with a partition plate 41 that divides its inner cavity into a water storage chamber 42 and an air intake chamber 43; an ultrasonic vibrating plate 44 is provided at the bottom of the water storage chamber 42; a second through hole 45 is provided on the partition plate 41 to connect the water storage chamber 42 and the air intake chamber 43, and a first one-way valve 46 is provided in the second through hole 45 to allow gas to flow from the air intake chamber 43 into the water storage chamber 42; the water storage chamber 42 is connected to the outside through a water inlet 47 on the side wall of the humidifier box 4; the water inlet 47 is located on the side wall of the humidifier box 4 facing the outside of the shell 1. The water storage chamber 42 is used to store clean water, and the ultrasonic vibrating plate 44 vibrates the water into fine water mist through its own high-intensity vibration. The air intake chamber 43 is used to allow airflow to flow into the water storage chamber 42, and the flowing airflow carries the fine water mist out of the spray nozzle 40.

[0034] In this embodiment, the water inlet 47 is connected to an external water supply tank (not shown in the figure) via a water pipe (not shown in the figure).

[0035] In this embodiment, the humidifier box 4 has an air inlet 48 on one side wall facing the control circuit board 2. An air pump 6 is also provided inside the housing 1. The air pump 6 is connected to the air inlet 48 via an air pipe assembly 60. The air pipe assembly 60 includes a first air pipe 600 fixedly connected to the output end of the air pump 6, and a second air pipe 601 slidably disposed at the other end of the first air pipe 600. The output end of the second air pipe 601 is located in the air inlet chamber 43. A second one-way valve 49 is provided on the air inlet 48 to allow gas to flow from the air pump 6 into the air inlet chamber 43. The air pump 6 provides power to the airflow entering the air inlet chamber 43 and the water storage chamber 42. The sliding arrangement of the first air pipe 600 and the second air pipe 601 is to accommodate the sliding of the humidifier box 4 within the housing 1. Furthermore, both the first one-way valve 46 and the second one-way valve 49 are umbrella-shaped one-way valves to prevent backflow of airflow and liquid.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
