DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] Temperature and humidity sensors are used to sense indoor temperature and humidity. Figure 1-2 As shown, the device comprises a support 100 and a host 200 , wherein the host 200 is detachably mounted on the support 100 . The host 200 comprises a housing 210 , an electronic board 220 , a sensing probe 230 and a display screen 240 .

[0034] In this embodiment, the host 200 and the bracket 100 are detachable, and the bracket 100 is fixed to a vertical plane such as a wall or a cabinet by adhesive or screws, and then the host 200 is installed on the bracket 100 to sense the indoor temperature;

[0035] When the temperature of other rooms needs to be sensed, the host 200 can be taken out for emergency use to measure the temperature and humidity of other rooms;

[0036] Alternatively, when the indoor venue is large, especially in a large area such as a factory, the user can take out the host 200 and walk to different locations to stop, detect the temperature and humidity of the area, and determine whether the indoor temperature and humidity are uneven.

[0037] The host 200 can be moved arbitrarily, and is more convenient to use.

[0038] Furthermore, a magnetic adsorption component 300 is provided between the bottom of the host 200 and the bracket 100, and between the bracket 100 and the shell 210, one of which is provided with a dovetail groove and the other is provided with a slider matching the dovetail groove; the bracket 100 and the shell 210 are slidably installed.

[0039] Specifically, the bracket 100 is provided with a supporting portion 110 for supporting the bottom of the host 200 , and a magnetic adsorption component 300 is provided between the supporting portion 110 and the bottom of the host 200 , and the magnetic adsorption component 300 is a magnet that attracts each other magnetically.

[0040] like Figure 1 As shown, after the bracket 100 is installed on the wall, the host 200 is installed on the bracket 100 from top to bottom, the bracket 100 is provided with a slider 120, the housing 210 is provided with a dovetail groove 211, and the host 200 is slidably installed on the bracket 100; and, during the installation process, due to the gravity of the host 200 and the suction force of the magnetic adsorption component 300, the host 200 is freely dropped for installation, and the installation is smoother and more convenient;

[0041] The magnetic adsorption component 300 comprises a first magnetic component and a second magnetic component, wherein the first magnetic component and the second magnetic component are magnets that attract each other magnetically; Figure 1 In the figure, only the first magnetic component in the magnetic adsorption assembly 300 is shown at the bottom of the bracket 100, while the second magnetic component is installed at the bottom of the shell 210, and the second magnetic component is not shown yet.

[0042] The housing 210 is made of plastic and comprises a first housing and a second housing that are interlocked with each other. A receiving cavity is formed inside the housing 210, and the electronic board 220 and the sensor probe 230 are both installed in the receiving cavity.

[0043] The first shell is provided with a display screen 240, the second shell is provided with a battery holder, and a battery 250 is installed in the battery holder; the electronic board 220 is provided with a charging interface. The entire host 200 is powered by a battery, and can be used wirelessly and moved at will. When the battery 250 is exhausted, it can be charged through the charging interface; or, ordinary batteries can be used, and they can be replaced when they are exhausted. In this design, a battery cover needs to be provided on the second shell, and the battery cover can be opened to facilitate battery replacement.

[0044] The display screen 240 is installed on the housing 210 and is electrically connected to the electronic board 220 . The display screen 240 at least displays temperature and humidity parameters.

[0045] Furthermore, the housing 210 is provided with a detection hole, which is disposed on the front side of the housing 210 , and the sensing probe 230 is exposed or protrudes from the detection hole.

[0046] The sensing probe 230 includes: a humidity probe 231 and a temperature probe 232. A sealing bracket 233 is provided corresponding to the detection hole. The sealing bracket 233 is hollow. The humidity probe 231 and the temperature probe 232 pass through the sealing bracket 233 to expose or extend out of the detection hole. The sealing bracket 233 plays a good sealing role to prevent moisture, dust, etc. from entering the interior of the housing 210.

[0047] The top of the humidity probe 231 and the temperature probe 232 is a flat surface, forming a detection plane, which is flush with the surface of the housing 210; the conventional humidity probe 231 and the temperature probe 232 are probe-type structures, which have little contact with the air and affect the detection accuracy; while in this embodiment, the top of the humidity probe 231 and the temperature probe 232 is designed as a detection plane, which increases the contact area and effectively improves the detection accuracy. .

[0048] Furthermore, if Figure 1 As shown, it also includes: LED lights 260; a circle of LED lights 260 is arranged around the display screen 240, and a light-transmitting ring is arranged on the housing 210 at a position corresponding to the LED lights 260, and the light-transmitting ring is buckled and installed on the housing 210;

[0049] LED light 260 can be used as a warning light or an atmosphere light, which is set according to the program. If the temperature and humidity sensor is used in the home, it can be used as a lamp to emit light at night to create an atmosphere, decoration, and indication. If it is used in a factory, it does not need to create an atmosphere and can be used directly as a warning light. For example, each work in production and processing will have certain requirements for temperature and humidity. If the temperature is too high and the humidity is too low, the weather will be dry and fires are prone to occur. The LED light 260 can serve as a reminder to remind the user that the current temperature is too high, the humidity is too low, etc.

[0050] The temperature and humidity sensor of the utility model has the characteristics that the host 200 can be moved arbitrarily and has high detection accuracy, and can accurately detect indoor temperature and humidity.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
