In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0030] In the related art, there are few all-in-one machines that can measure ear temperature and forehead temperature simultaneously, and there is no all-in-one machine that can be waterproof. When a household ear temperature and forehead temperature all-in-one machine is used by an adult or a child, there is a risk of water immersion. Therefore, it is necessary for the device to be waterproof.

[0031] In view of the problems in the related art, the present embodiment provides an ear temperature and forehead temperature all-in-one machine, which includes a housing 20 and a waterproof temperature measurement probe 10. One end of the housing 20 has an assembly chamber 24, and a connection and sealing structure is provided in the assembly chamber 24; the waterproof temperature measurement probe 10 is arranged at one end of the housing 20 through the connection and sealing structure. The waterproof temperature measurement probe 10 includes a probe housing 11, a metal column 12, a metal cap 13, a sealing gasket 17 and a temperature measurement sensor 14; an installation chamber is formed in the probe housing 11, and a temperature measurement hole 112 is opened at one end of the probe housing 11; the metal column 12 is arranged in the installation chamber, and a through installation through hole is axially opened in the metal column 12. A first sealing ring 15 is sleeved on the outer wall of the metal column 12, and the first sealing ring 15 abuts against the inner wall surface of the probe housing 11; one end of the metal cap 13 is connected to the metal column 12, the other end of the metal cap 13 has a retaining ring portion, and a through limiting through hole is axially opened in the metal cap 13; the sealing gasket 17 is arranged in the limiting through hole and abuts against the retaining ring portion; one end of the temperature measurement sensor 14 is located in the limiting through hole and abuts against the sealing gasket 17, and the other end of the temperature measurement sensor 14 is located in the installation through hole. One end of the temperature measurement probe is connected to the main body of the temperature measurement device, and the other end protrudes outward to measure the temperature by using this end portion. In the present embodiment, the temperature measurement sensor 14 is arranged inside the metal cap 13 and the metal column 12, and a sealing gasket 17 is arranged on the retaining ring portion of the metal cap 13 to realize the sealing inside the temperature measurement sensor 14. Furthermore, through the setting of the first sealing ring 15 on the metal column 12, the sealing between the metal column 12 and the installation chamber can be realized, preventing water seepage inside the temperature measurement sensor 14, improving the service life of the temperature measurement probe, and improving the measurement accuracy of the temperature measurement probe.

[0032] It can be understood that usually one end of the temperature measurement probe is connected to the housing 20, and the temperature measurement probe protrudes from the main body part of the temperature measurement device, which makes the temperature measurement probe part prone to water seepage, and mainly seeps in from the end part of the temperature measurement probe (the end of the temperature measurement hole 112). Specifically, the water seepage at one end of the probe may mainly seep in through the limiting through hole of the metal cap 13 part and the gap between the metal cap 13 and the installation chamber. In this embodiment, the metal cap 13 is located at one end of the temperature measurement hole 112, and a sealing washer 17 is provided inside the metal cap 13, which makes it difficult for water seepage to seep in through the limiting through hole inside the metal cap 13, realizing the sealing of the limiting through hole inside the metal cap 13, and the setting of the first sealing ring 15 on the metal column 12 can further realize the sealing between the installation chamber and the metal column 12, so that the water seepage from the probe end is difficult to seep into the inside of the temperature measurement sensor 14 through the temperature measurement sensor channel (that is, the channel formed by the through holes opened on the metal column and the metal cap), realizing the sealing of the probe end.

[0033] The metal cap 13 as a whole is a hollow ring-shaped structure. One end of the metal cap 13 is an open end, and the open end is connected to the metal column 12. The other end of the metal cap 13 has a retaining ring part, and the retaining ring part is integrally formed with the metal cap 13. The retaining ring part makes the diameter of the other end of the metal cap 13 smaller than that of the open end, so that the sealing washer 17 can be closely abutted against the retaining ring part, realizing the limitation through the retaining ring part and ensuring the pressing and abutting of the temperature measurement probe and the sealing washer 17.

[0034] The metal column 12 as a whole is a tubular structure. One end of it is connected to the metal cap 13, and the other end is located in the installation through hole, or the other end can also be flush with the end face of the probe housing 11. After the metal column 12 and the metal cap 13 are connected, their limiting through holes and installation through holes are communicated to form a relatively sealed space, and the temperature measurement sensor 14 is located in this space, and one end of the temperature measurement sensor 14 abuts against the sealing washer 17 to realize the overall sealing.

[0035] In a specific embodiment, the installation through hole and the limiting through hole are concentrically arranged, which is beneficial to the installation of the temperature measurement sensor 14 and realizes the rapid assembly of the temperature measurement sensor 14.

[0036] The probe housing 11 as a whole forms a structure similar to a frustum of a cone. The end away from the connection with the main body of the temperature measurement device is the small-diameter end, and a temperature measurement hole 112 is provided at this end. The other end is connected to the main body of the temperature measurement device. When measuring the side temperature, the temperature is measured by bringing one end of the temperature measurement hole 112 close to the temperature measurement area.

[0037] In a specific example, the inner diameter of the installation chamber gradually expands from one end of the temperature measuring hole 112 to the other end, forming a shape similar to a tapered hole. And a stepped portion is provided at one end of the temperature measuring hole 112 where the installation chamber is located. Correspondingly, a corresponding shoulder is provided on the outer wall surface of the metal cap 13. The shoulder and the stepped portion cooperate to limit the position, thereby realizing the position limitation of the metal cap 13 and ensuring the determination of the installation position of the metal cap 13.

[0038] When specifically arranged, the metal column 12 is inserted into the metal cap 13, and the metal column 12 and the metal cap 13 are in interference fit. The metal column 12 and the metal cap 13 can be connected and matched in various ways. For example, threaded connection, sealed clamping connection and other methods are all available. In this embodiment, the stable connection between the two is realized through the insertion fit and the interference fit between the two, and the sealing performance of the connection between the two is ensured.

[0039] It can be understood that, compared with other connection methods, the insertion method is beneficial to assembly, and can make the metal cap 13 abut against the sealing washer 17, improving the sealing effect. For example, during the insertion assembly, it is necessary to have an interference fit between the metal column 12 and the metal cap 13, which will inevitably exert an axial force on the metal cap 13, so that the metal cap 13 can fit more closely with the inner wall surface of the installation chamber.

[0040] When specifically arranged, the sealing washer 17 includes a silicone washer. The silicone washer has good elasticity and elastic recovery. Even under long-term pressure, it can maintain good sealing performance, is not easy to deform, and helps to maintain the sealing of the equipment. And the silicone washer has good chemical resistance and can resist the erosion of various chemical substances, including acids, alkalis, solvents, etc.

[0041] According to an embodiment provided by the present utility model, a limiting step is provided on the inner wall of the limiting through hole, and a limiting flange 141 is provided at one end corresponding to the temperature measuring sensor 14. The limiting flange 141 and the limiting step cooperate to limit the position, and the end surface of the metal column 12 abuts against the limiting flange 141. The temperature measuring sensor 14 needs to have a stable structural relationship during the temperature measurement process. In this embodiment, a limiting flange 141 is provided on the temperature measuring sensor 14, and the limiting flange 141 is limited on the limiting step through the metal column 12, realizing the stable connection of the temperature measuring sensor 14.

[0042] It can be understood that the metal column 12 is inserted into the metal cap 13 by the insertion method and contacts and abuts against the limiting flange 141 in the metal cap 13. This enables the limiting flange 141 on the temperature measuring sensor 14 to be positioned and fixed through the metal column 12 and the limiting step. That is, after the metal column 12 is inserted into the metal cap 13, a positioning gap is formed between the end surface of the metal column 12 and the limiting step, and the limiting flange 141 is located in this positioning gap to realize the fixation of the temperature measuring sensor 14, improving the overall stability.

[0043] Furthermore, the limiting flange 141 is a structure of the temperature measuring sensor 14 itself, and the limiting flange 141 is integrally provided with the main body of the temperature measuring sensor 14, which ensures the stability of the temperature measuring sensor 14 when the metal column 12 is inserted, and drives one end of the temperature measuring sensor 14 to abut and press against the sealing limiting ring during the installation process of the metal column 12 (inserting and pushing), improving the sealing performance of the connection of the sealing limiting ring.

[0044] In a specific embodiment, the outer wall of the metal column 12 has a mating step adapted to the inner wall contour of the installation chamber, and the first sealing ring 15 is located at the mating step. In the probe waterproof design, this embodiment adopts two layers of waterproofing. The first layer is that the sealing gasket 17 seals the limiting through hole in the metal cap 13 with one end of the temperature measuring sensor 14, and the second layer is the first sealing ring 15 sleeved on the metal column 12. Through the two layers of waterproofing, it can prevent external seepage water from seeping into the temperature measuring hole 112, improving the waterproof performance of the probe.

[0045] In a specific implementation manner, the inner wall surface of the installation chamber has an inclined step surface, and correspondingly, the outer wall of the metal column 12 has a mating step. By setting the first sealing ring 15 at the position of the mating step, the first sealing ring can cooperate with the inclined step surface, so that the step surface can squeeze the first sealing ring 15 to achieve the sealing between the metal column 12 and the installation chamber, improving the overall waterproof effect.

[0046] It can be understood that in principle, the outer wall surface of the metal cap 13 is in close contact with the inner wall surface of the installation chamber. This method ensures that there is no seepage gap between the metal cap 13 and the installation chamber, thus preventing external seepage water from entering the installation chamber. In this embodiment, through the setting of the first sealing ring 15, the waterproof effect is further improved, so that even if seepage water enters the installation chamber, it will not further seep in, improving the waterproof performance.

[0047] During specific setting, the outer wall of the probe housing 11 away from the temperature measuring hole 112 is provided with an outward protruding limiting protrusion 111, and a second sealing ring 16 is provided on the limiting protrusion 111. The probe needs to be connected to the main body part of the temperature measuring device. In this embodiment, through the setting of the limiting protrusion 111, when the probe is connected to the main body of the temperature measuring device, it can also be hermetically connected, thus providing a reliable solution for the overall waterproofing of the temperature measuring device.

[0048] In an embodiment provided by the present utility model, the ear temperature and forehead temperature integrated machine further includes a forehead temperature cap; the forehead temperature cap is detachably arranged at one end of the housing 20 close to the waterproof temperature measuring probe 10, and the forehead temperature cap has an accommodation space capable of accommodating the waterproof temperature measuring probe 10. When designing for waterproofing, it is mainly the waterproof design at the connection position. In this embodiment, by arranging a connection sealing structure in the assembly chamber 24, the waterproof temperature measuring probe 10 is hermetically connected to the housing 20 (i.e., the temperature measuring device main body mentioned above), ensuring the overall waterproof design and improving the overall waterproof performance.

[0049] Specifically, the housing 20 can be an integral one-piece structure. Through the integral one-piece structure, the housing 20 can be a sealed housing 20, and only an assembly chamber 24 is provided at one end of the housing 20. Through the sealed connection between the assembly chamber 24 and the waterproof temperature measuring probe 10, the overall waterproofing of the entire temperature measuring device is realized, improving the overall waterproof performance and service life. Of course, the housing 20 can also be a split structure.

[0050] Among them, the forehead temperature cap is snap-connected to the housing 20, and the accommodation space in the forehead temperature cap can accommodate the main body part of the probe. An opening is provided on the end face of the forehead temperature cap facing the probe part, and the end of the probe is located in the opening, so that when performing forehead temperature detection, the forehead temperature cap is attached to the forehead for temperature measurement. Specifically, the surface of the forehead temperature cap for attaching to the forehead is configured as a curved surface structure. Through the design of the curved surface structure, the forehead temperature cap can

[0051] For example, when the housing 20 needs to perform ear temperature detection, the forehead temperature cap is removed so that the main body part of the probe is exposed, facilitating insertion into the ear canal for temperature measurement.

[0052] In a specific split structure, the housing 20 includes a first outer shell 21 and a second outer shell 22. The first outer shell 21 and the second outer shell 22 are detachably connected and form an assembly chamber 24; among them, a rubber strip groove is provided around the edge of the first outer shell 21, and a waterproof strip 23 is provided in the rubber strip groove. The waterproof strip 23 is arranged between the first outer shell 21 and the second outer shell 22. In this embodiment, the housing 20 is set as a split structure, and its waterproofing is realized by arranging a waterproof strip 23 between the two housings 20.

[0053] It can be understood that the split design facilitates the overall assembly, can quickly realize the assembly of the waterproof temperature measuring probe 10 part, and through the arrangement of the waterproof strip 23 between the two housings 20, the waterproof strip 23 is squeezed during connection to achieve the sealing between the two split housings 20.

[0054] In specific settings, an installation space is formed inside the first housing 21 and the second housing 22, and the installation space is used to install primary components such as a main control board, a screen protection probe, and a button component. Among them, a battery compartment is also provided on the first housing 21 or the second housing 22. When connecting, a waterproof rubber strip is provided on the battery cover outside the battery compartment, so that the battery cover can seal the battery compartment and prevent water seepage. When the first housing 21 is connected to the second housing 22, it is connected and fixed by means of buckles and screws, so that a split connection between the two can be achieved.

[0055] In the specific embodiment provided by the present utility model, a mating limiting portion is provided inside the assembly chamber 24, and the mating limiting portion is used for mating and limiting with the waterproof temperature probe 10; the connection sealing structure includes a sealing rib 25, a fixing rib 26 and a pressure rib 27. The sealing rib 25 is provided inside the assembly chamber 24, and the sealing rib 25 is used for mating and sealing with the waterproof temperature probe 10. The fixing rib 26 abuts against the end of the probe housing 11, and the pressure rib 27 abuts against the end of the metal column 12. When the waterproof temperature probe 10 is connected, stability and waterproofness are required. Through the setting of the fixing rib 26 and the pressure rib 27, the overall stability of the waterproof probe can be achieved. Through the setting of the sealing rib 25, the sealing performance after the waterproof probe is connected to the housing 20 can be achieved, so as to realize the sealing of the connection position.

[0056] It can be understood that when the entire all-in-one machine needs to be designed for waterproofing, it is necessary to ensure the waterproofing of the probe part, the housing 20 part, and the connection position between the probe and the housing 20. The waterproofing of the probe and the housing 20 can be clearly known through the foregoing description. In this embodiment, first, the limiting connection with the waterproof temperature probe 10 is realized through the mating limiting portion. When connecting, the sealing rib 25 abuts against the second sealing ring 16, and the waterproof temperature probe 10 is hermetically connected to the assembly chamber 24, so as to ensure the sealing performance of the connection of the waterproof temperature probe 10. The fixing rib 26 is arranged at the bottom of the assembly chamber 24 (that is, the end of the assembly chamber 24 close to the housing 20). The size design of the entire assembly chamber 24 makes the end of the probe housing 11 abut against the fixing rib 26 and the pressure rib 27 abut against the metal column 12 after the waterproof temperature probe 10 is installed in the assembly chamber 24, making the connection of the entire waterproof temperature probe 10 tighter and ensuring the stability of the connection of the waterproof temperature probe 10.

[0057] In specific settings, the sealing rib 25 has a rib surface structure inclined at 45 degrees, which makes the sealing effect more significant when the sealing rib 25 abuts against the second sealing ring 16. That is, when the inclined surface structure abuts against the second sealing ring 16, the pressing degree of its inclined surface is higher and the sealing effect is better.

[0058] For example, such as Figure 3-5As shown, a connection sealing structure is provided on both the first housing 21 and the second housing 22, that is, sealing ribs 25, fixing ribs 26 and pressure ribs 27 are provided on both the first housing 21 and the second housing 22. The structural ribs on each housing 20 can limit the waterproof temperature measuring probe 10 after the housings 20 are connected, improving the overall stability. Moreover, the structural ribs on the first housing 21 and the second housing 22 form an annular rib structure after the two housings 20 are connected (that is, the sealing ribs 25, fixing ribs 26 and pressure ribs 27 are combined to form an annular structure), and the fastening of the connection of the waterproof temperature measuring probe 10 can be improved through the annular rib structure.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
