Description

Technical Field

[0001] This utility model belongs to the technical field of infant and child bath products, and specifically relates to a children's water thermometer. Background Technology

[0002] In the field of infant care, children's skin is delicate and more sensitive to temperature changes than adults. Relying solely on adults' temperature perception can easily cause discomfort for children, and even lead to minor burns. Therefore, measuring water temperature with a thermometer to determine whether the current water temperature is suitable has become a key step in ensuring bathing safety and comfort. Traditional children's thermometers usually adopt an integrated sealed design, fixing the temperature measuring module inside the shell and measuring the water temperature by having the power contact or probe protrude from the shell to contact the water. However, because the temperature measuring module is controlled by a switch, it is easy to forget to use it and continue to discharge, reducing the battery's lifespan. Furthermore, since the temperature measuring module is fixed inside the shell, it cannot be disassembled and replaced or used separately, making it inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a children's water thermometer. The technical problem this invention aims to solve is: how to improve portability.

[0004] The purpose of this utility model can be achieved through the following technical solution: A children's water thermometer, including a shell and a temperature measuring module with a built-in battery. The temperature measuring module includes a temperature measuring body and a mounting base. The temperature measuring body is connected to the shell through the mounting base. The temperature measuring body is characterized by having two water-conducting electrical contacts on one side. The mounting base is detachably connected to the shell. When the mounting base is snapped and fixed to the shell, the temperature measuring body is clamped and fixed between the shell and the mounting base. The electrical contacts pass through the mounting base and are connected to the outside.

[0005] This application, based on the existing method of mounting a temperature measuring module on the housing, separates the temperature measuring module into a mounting base and a temperature measuring body for temperature measurement. The mounting base, in conjunction with the housing, clamps the temperature measuring body between the housing and the mounting base, preventing the temperature measuring body from shaking due to buoyancy during use. Furthermore, the mounting base and housing are detachably connected, facilitating the replacement and use of the temperature measuring body after disassembly. In addition, this application employs a dual-contact structure, utilizing the energizing effect of the dual-contacts when wet to prevent continuous discharge during non-use, thus improving battery life. Moreover, it eliminates the need to press an additional switch to start the temperature measuring body and allows it to be removed for independent use, enhancing the convenience of using the temperature measuring body. Furthermore, by using only one contact for temperature measurement, it achieves the effect of temperature measurement while the device is powered on, further improving portability.

[0006] In the aforementioned children's thermometer, the temperature measuring body contains a circuit board and a battery that powers the circuit board. The two energized contacts are used to control the connection between the battery and the circuit board. The temperature measuring probe on the circuit board is located inside one of the energized contacts.

[0007] In the aforementioned children's water thermometer, a charging interface is provided between the two energized contacts.

[0008] In the aforementioned children's thermometer, the housing has a cavity for placing the temperature measuring module, the cavity wall has a snap-fit ​​groove, and one side of the snap-fit ​​groove has an opening.

[0009] In the aforementioned children's thermometer, the mounting base is provided with a strip-shaped protrusion. When the mounting base rotates a certain angle within the accommodating cavity, the strip-shaped protrusion is inserted into the snap-fit ​​groove through the opening, and one side of the strip-shaped protrusion abuts against the snap-fit ​​side wall.

[0010] In the aforementioned children's thermometer, a guide slope is provided on one side of the opening. When the mounting base is rotated at a certain angle, the strip-shaped protrusion enters the snap-fit ​​groove through the guide slope and abuts against the side wall of the snap-fit ​​groove. This rotational snap-fit ​​method simplifies the fixing of the mounting base and the housing, making it easier for users to install and disassemble.

[0011] In the above-mentioned children's water thermometer, a water spraying component is provided in the cavity of the housing, the cavity wall of the accommodating cavity separates the temperature measuring module from the water spraying component, the housing has a water inlet for water to enter the housing, and the inlet of the water spraying component is connected to the cavity inside the housing.

[0012] In the aforementioned children's water thermometer, the water spray component includes a push-button switch, and the housing is provided with a button that corresponds to the push-button switch.

[0013] In the aforementioned children's thermometer, two markings are provided on the rear side of the housing. The mounting base is snapped onto the rear side of the housing, and an indicator protrusion is provided on the mounting base, which corresponds to the two markings. The cooperation between the markings and the indicator protrusion makes it easy for the user to determine the current status.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application clamps the temperature measuring body within the accommodating cavity formed by the mounting base and the housing, preventing the temperature measuring body from moving back and forth. The mounting base and the housing are engaged by a snap-fit ​​groove and a strip-shaped protrusion, which facilitates the disassembly of the temperature measuring body to meet the needs of maintenance, replacement, and other situations where the temperature measuring body needs to be disassembled, thereby improving the flexibility and portability of use.

[0016] 2. This application adopts a dual-current contact structure. By using bath water as a conductor, the dual-current contact controls the connection between the battery and the circuit board. At the same time, the temperature probe measures the water temperature, avoiding excessive discharge caused by continuous conduction when not in use, thus improving the battery's endurance. Furthermore, it eliminates the need for an external switch to turn the temperature measurement module on and off, improving portability.

[0017] 3. The housing of this application is also provided with a water spray component, which increases the fun of bathing, and the cavity wall of the accommodating cavity separates the temperature measuring body from the water spray component to prevent water from entering the temperature measuring body.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1 and Figure 2As shown, this application describes a battery-powered 2D2D children's water thermometer, which includes a housing 1 and a temperature measuring module 2 located inside the housing 1. The housing 1 is provided with a button 1b and two water inlets 1d. Water can enter the cavity of the housing 1 through the inlets and be sprayed out from the front end by a water spray assembly 3. The housing 1 is also provided with a receiving chamber for accommodating the temperature measuring module 2. The water spray assembly 3 and the temperature measuring module 2 are separated by the cavity wall of the receiving chamber. The temperature measuring module 2 includes a mounting base 2b and a temperature measuring body 2a. The temperature measuring body 2a is provided with a strip-shaped protrusion. The cavity wall of the receiving chamber 1a is provided with a snap-fit ​​groove 1a1. One end of the snap-fit ​​groove 1a1 is provided with an opening 1a1a and a guide slope 1a1b located at the opening 1a1a.

[0026] It is worth mentioning that, such as Figure 2 As shown, the battery 2d2d children's water thermometer is also equipped with a water spray component 3. The housing 1 is equipped with a button 1b and a water inlet 1d. The water spray component 3 is located inside the housing 1, and one end of the water spray component 3 extends forward and is connected to the button 1b. The temperature measuring module 2 is separated from the water spray component 3 by the cavity wall of the accommodating cavity 1a.

[0027] like Figure 3 and Figure 4 As shown, the mounting base 2b is fixed to the rear side of the housing 1. The rear side of the housing 1 is provided with a mark 1c indicating unlocking and locking. The mounting base 2b is provided with an indicator protrusion 2b2 corresponding to the mark 1c. The temperature measuring body 2a is provided with two power contacts 2a1. The temperature measuring body 2a is provided with a battery 2d and a circuit board 2e. The two power contacts 2a1 are placed in parallel, and a charging interface 2c is provided between the two power contacts 2a1. The two power contacts 2a1 and the charging interface 2c are all protruding from the mounting base 2b.

[0028] like Figure 4 and Figure 5 As shown, the housing 1 has a cavity 1a for accommodating the temperature measuring module 2. The mounting base 2b of the temperature measuring module 2 is snapped into the housing 1. Specifically, the inner wall of the cavity 1a has a snap-fit ​​groove 1a1. The outer periphery of the mounting base 2b has a strip-shaped protrusion 2b1. The rear side of the mounting base 2b has a cover plate. When the temperature measuring module 2 is placed in the cavity 1a of the housing 1 and locked, the strip-shaped protrusion 2b1 enters the snap-fit ​​groove 1a1 under the rotation of the mounting base 2b, and abuts against the inner wall of the snap-fit ​​groove 1a1. The temperature measuring body 2a is clamped in the cavity 1a by the cooperation of the mounting base 2b and the housing 1. The charging interface 2c and the two power contacts 2a1 pass through the mounting base 2b. When the temperature measuring module 2 needs to be disassembled, the mounting base 2b rotates, and the strip-shaped protrusion separates from the module under the action of the user.

[0029] In summary, this application, as a 2d2d water thermometer with a built-in battery, addresses the limitations of existing water thermometers. These thermometers can only measure temperature using a single probe and are placed in bathwater. Their integrated design makes it difficult to replace the measuring element in case of damage, and their large size restricts their usability. To avoid these problems, this application increases the contact area with the water by placing the thermometer inside the housing 1. Furthermore, it uses a detachable mounting base 2b connected to the housing 1 to clamp the temperature measuring element 2a within the housing 1. Within the cavity 1a, while retaining the housing, it is convenient for the user to replace the damaged temperature measuring body 2a, or to remove the working temperature measuring body 2a separately for temperature measurement, or to place the temperature measuring module 2 into a housing 1 of other shapes, thus improving the flexibility of the temperature measuring body 2a in use. In particular, by setting a guide slope 1a1b at one end of the snap-fit ​​groove 1a1 for disassembly and installation of the mounting base, it is convenient for the user to install and replace the strip protrusion 2b1 as it is inserted through the opening on the snap-fit ​​groove 1a1, thus improving the flexibility and portability of the temperature measuring body in use.

[0030] It is worth mentioning that, based on the existing water thermometer with a built-in battery 2d2d, this application adopts a structure with dual energized contacts 2a1. When the user places the water thermometer above or below the water, the temperature measuring module 2 automatically turns on after the two energized contacts 2a1 come into contact with the water. The temperature is then measured by the temperature probe 2e1 inside one of the energized contacts 2a1. This avoids the problem of short battery life caused by over-discharge of the battery 2d2d inside the temperature measuring body 2a when not in use. The battery 2d2d utilizes the conductivity of water to control the connection and disconnection between the battery 2d2d and the circuit board 2e2e through the dual energized contacts, achieving automatic conduction when placed in water and automatic power-off when removed from the water, further improving portability.

[0031] In addition, this application also provides a water inlet 1d on the housing 1 and a water spraying component 3 inside the housing 1. By pressing the button 1b on the housing 1 and the press switch 3a on the water spraying component 3, the water spraying component 3 is controlled to spray water outward through the nozzle on the housing 1, thereby enhancing the fun of bathing.
