Fig. 1 is a cross-sectional view of a temperature measuring device according to an exemplary embodiment, and as shown in fig. 1, the temperature measuring device includes an outer frame 1, a temperature measuring assembly 2, an inner frame 3, and an elastic member 4. The outer frame 1 comprises a first end and a second end, the temperature measuring component 2 penetrates through the first end of the outer frame 1, and at least part of the inner frame 3 is located inside the second end of the outer frame 1. The elastic member 4 is located between the temperature measuring module 2 and the inner frame 3, and the elastic member 4 can provide an elastic restoring force that keeps the temperature measuring housing 21 penetrating the outer frame 1.

It should be noted that the temperature measuring component 2 is used for measuring the temperature of an article, for example, the article is placed on the temperature measuring component 2, the bottom surface of the article is in contact with one end of the temperature measuring component 2 extending out of the outer frame 1, the temperature measuring component 2 descends under the action of the gravity of the article and compresses the elastic component 4 until the temperature measuring component 2 completely enters the outer frame 1, or the temperature measuring component 2 is flush with the object placing plate 6 for supporting the article. So the bottom surface of the article is tightly propped against the temperature measuring component 2, so that the temperature measuring component 2 can measure the temperature of the article.

The connection between the external frame 1 and the thermometric assembly 2 will be described.

As shown in fig. 1, the first end of the outer frame 1 is sleeved outside the temperature measuring component 2, and the second end of the outer frame 1 has a first water outlet 11. A first flow guide channel is defined between the outer frame 1 and the temperature measuring component 2 and is communicated with the first water outlet 11, so that liquid can flow into the outer frame 1 through the first flow guide channel and flow out of the first water outlet 11 of the outer frame 1. That is to say, the first diversion channel is limited by the outer frame 1 and the temperature measurement shell 21 which are sleeved with each other, so that the diversion effect on the liquid is realized, the diversion structure can be simplified, and the manufacturing cost of the device is further reduced.

In another possible implementation manner, the diameter of the temperature measuring component 2 can be smaller than the diameter of the opening of the outer frame 1, and an annular groove is formed between the temperature measuring component 2 and the outer frame 1, and the annular groove can form a first flow guide channel.

In still another possible implementation manner, a diameter of a part of the temperature measuring components 2 may be equal to the diameter of the opening of the outer frame 1, and a diameter of a part of the temperature measuring components 2 may be smaller than the diameter of the opening of the outer frame 1.

Optionally, one end of the external frame 1 is configured to abut against the temperature measuring component 2 to limit the length of the temperature measuring component 2 penetrating out of the external frame 1. That is to say, the length of the temperature measuring component 2 penetrating through the outer frame 1 is limited by one end of the outer frame 1, so that the elastic deformation length of the elastic part 4 is controllable, and the temperature measuring component 2 is not easy to come out of the outer frame 1.

Alternatively, the outer frame 1 may have a first center hole and a second center hole communicating with each other, the first center hole may have a diameter smaller than that of the second center hole, and a support boss may be provided between the first center hole and the second center hole to connect the first center hole and the second center hole.

For example, as shown in fig. 1, the external frame 1 may include a bottom wall and a side wall connected to an outer periphery of the bottom wall and extending toward one side, and the bottom wall and the side wall may define a receiving space. The first central hole mentioned above may be provided in the bottom wall of the outer frame 1 and the side wall of the outer frame 1 may form the second central hole. The temperature measuring component 2 is outwardly arranged on the bottom wall of the outer frame 1 from the inside of the accommodating space (namely arranged on the first central hole). The end of the side wall of the outer frame 1 remote from the bottom wall may be open so as to form a first water outlet 11. It should be noted that the external frame 1 may be arranged in other ways, which is only an example, and the structure of the external frame 1 is not limited specifically.

With reference to fig. 1, the temperature measuring assembly 2 includes a temperature measuring housing 21 and a temperature measuring body 22, and the temperature measuring body 22 is embedded in the temperature measuring housing 21.

The temperature measuring body 22 is a temperature sensor, and may be an NTC thermistor or others.

The temperature measuring body 22 is connected to the controller through a wire 5, and the controller is configured to receive a temperature signal measured by the temperature measuring body 22 and process the temperature signal to obtain a control signal. The control signal can be used for controlling the on-off of the power supply module, the adjustment of the temperature control module, the on-off of the alarm module, the display of the display module or the like.

That is, one end of the elastic member 4 is disposed inside the mounting groove 211 so that the groove wall of the mounting groove 211 can restrict displacement of both sides of the elastic member 4, and the groove bottom of the mounting groove 211 abuts against one end portion of the elastic member 4 so as to restrict displacement of the elastic member 4 in the axial direction; thus, not only is a mounting position provided for one end of the elastic member 4, but also movement of one end of the elastic member 4 is restricted.

Optionally, the bottom of the mounting groove 211 is provided with a mounting flange 212, a predetermined distance is provided between the mounting flange 212 and the groove wall of the mounting groove 211, and the mounting flange 212 is sleeved outside the temperature measuring body 22. That is, the liquid flows through the first flow guide channel between the temperature measuring housing 21 and the inner wall of the outer frame 1, and the temperature measuring body 22 and the lead 5 are located in the mounting recess 211 of the temperature measuring housing 21, so that the mounting recess 211 can separate the liquid from the temperature measuring body 22 and the lead 5. In addition, the temperature measuring body 22 is embedded in the mounting flange 212 in the mounting groove 211, so that the temperature measuring body 22 and the lead 5 can be further isolated from the liquid of the first diversion channel.

That is, the large diameter end of the elastic member 4 is connected to the temperature measuring case 21, and the small diameter end of the elastic member 4 is connected to the inner frame 3. When the elastic part 4 is compressed, the force on the elastic part 4 is transmitted from the large-diameter end to the small-diameter end, so that the force is gradually concentrated towards the axis of the elastic part 4, and the outward inclination of the elastic part 4 in the deformation process is avoided; when the elastic element 4 recovers to deform, the force on the elastic element 4 is transmitted from the small-diameter end to the large-diameter end, and the contact surface between the elastic element 4 and the temperature measuring shell 21 is large, so that the force applied to the temperature measuring shell 21 by the elastic element 4 can be distributed in a balanced manner.

The structure of the internal frame 3 will be described below.

Optionally, the inner frame 3 comprises a support platform 31, and the support platform 31 is used for abutting against one end of the elastic member 4; the temperature measuring component 2 is connected with the controller through a lead 5, and the supporting platform 31 is used for the lead 5 to pass through. That is, the lead 5 extending out of the temperature measuring unit 2 passes through the supporting platform 31 and then extends out of the outer frame 1. The support platform 31 may act as a stop for the wires 5 so that the interior space of the external frame 1 remains clean.

Wherein, screw in groove 12 can include the axial section that sets up along the axial of outrigger 1, the circumference section that sets up along the circumference of outrigger 1, and the circumference section is the setting of buckling for the axial section, and the one end that the circumference section was kept away from to the axial section is the opening setting. When the outer frame 1 is installed, the screw-in block 311 can enter the axial section from the opening of the axial section along the axial direction of the outer frame 1. When the screwing-in block 311 moves to the junction of the axial section and the circumferential section, the supporting platform 31 is rotated, so that the screwing-in block 311 enters the circumferential section until one side of the screwing-in block 311 abuts against the groove wall of the circumferential section.

Optionally, the external frame 1 further has a clamping groove, the clamping groove is communicated with the screw-in groove 12, the screw-in block 311 is provided with a clamping protrusion, and the clamping protrusion is coupled to the clamping groove.

Optionally, the inner frame 3 further includes a second mounting protrusion 33, and the second mounting protrusion 33 is disposed on the supporting platform 31 and extends toward the first water outlet 11; the first mounting protrusion 32, the support platform 31 and the second mounting protrusion 33 are used for the lead 5 to pass through. That is, the lead 5 extending out of the temperature measuring case 21 passes through the first mounting protrusion 32, the support platform 31, and the second mounting protrusion 33, and then extends out of the outer frame 1. Thus, the first mounting protrusion 32, the supporting platform 31 and the second mounting protrusion 33 can isolate the inner wire 5 from the outer second flow guiding channel to prevent the wire 5 from being affected by moisture. In addition, the wire 5 is limited, so that the inner space of the outer frame 1 is kept clean.
