Description

Technical fields:

[0001] This utility model belongs to the technical field of temperature measurement devices, and specifically refers to a water thermometer. Background technology:

[0002] Currently, bathtubs, washbasins, and sitz baths that can display water temperature are available on the market. These typically include a thermometer installed inside the tub, basin, or sitz bath. The thermometer is battery-powered. Since batteries have a limited lifespan, the thermometer will not function properly when the battery is dead. Because the upper and lower casings of the thermometer are sealed, users cannot replace the power source by disassembling the casings. Therefore, the entire thermometer needs to be replaced. This increases the user's cost if they purchase a replacement themselves, and increases the manufacturer's expenses if the manufacturer provides a new one free of charge. This results in a poor user experience for both users and manufacturers. Summary of the Invention:

[0003] The purpose of this invention is to provide a water thermometer that can charge batteries, extend their service life, and improve the user experience.

[0004] This utility model is implemented as follows:

[0005] A water thermometer includes an upper housing and a lower housing, which are sealed together. A circuit board mounting base is provided inside the lower housing, and the circuit board is mounted on the circuit board mounting base. The circuit board is connected to a temperature sensor and a display for displaying the temperature sensed by the temperature sensor. The temperature sensor, the display, and the circuit board are powered by a battery. A Type-C connector for charging the battery is also connected to the circuit board. The lower housing has a socket corresponding to the Type-C connector, and the Type-C connector is sealed to the lower housing.

[0006] In the aforementioned water thermometer, at least one positioning protrusion is provided on the lower housing, and the upper housing is provided with insertion holes whose positions and numbers correspond one-to-one with the positioning protrusions. The upper housing is disposed on the lower housing, and the positioning protrusions are inserted into the insertion holes.

[0007] In the aforementioned thermometer, the upper housing and the lower housing are connected by an ultrasonic sealing connection.

[0008] In one of the above-mentioned water thermometers, a decorative ring is provided on the outer ring of the upper housing.

[0009] In the aforementioned water thermometer, the circuit board mounting base includes a first column surrounding the circuit board, a first limiting post at the upper end of the first column, and the circuit board supported on the upper surface of the first column.

[0010] In the aforementioned thermometer, the upper and lower housings are racetrack-shaped or rectangular. The first column is distributed along the side walls at both ends of the lower housing, and a second column is provided on the inner bottom surface of the lower housing. A second limiting column is provided at the upper end of the second column. The second column forms a circuit board mounting base along the first column distributed along the side wall at one end of the lower housing.

[0011] In the aforementioned thermometer, the Type-C connector is sealed to the lower housing via a sealing gasket or sealant.

[0012] In the aforementioned water thermometer, the Type-C connector and the lower housing are integrally injection molded to achieve a seal.

[0013] In the aforementioned water thermometer, the temperature sensor is connected to the circuit board via a wire, and a wire through hole is provided on the lower housing. The wire is sealed to the wire through hole by a sealing gasket or sealant.

[0014] In the aforementioned thermometer, the lower housing includes a base plate and a side plate surrounding the outer edge of the base plate. The upper and lower planes of the base plate simultaneously bulge upward to form a boss. The socket is located on the boss, and the Type-C connector is sealed to the boss.

Detailed implementation method:

[0029] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —10:

[0030] This utility model provides a water thermometer, which includes an upper housing 1 and a lower housing 2, which are sealed together. A circuit board mounting base is provided inside the lower housing 2, and a circuit board 3 is mounted on the circuit board mounting base. The circuit board 3 is connected to a temperature sensor 4 and a display 5 for displaying the temperature sensed by the temperature sensor 4. The temperature sensor 4, the display 5, and the circuit board 6 are powered by a battery. A Type-C connector 6 for charging the battery is also connected to the circuit board 3. The lower housing 2 is provided with a socket 7 corresponding to the Type-C connector 6, and the Type-C connector 6 is sealed together with the lower housing 2.

[0031] This invention can be installed in children's bathtubs, washbasins, and other places where temperature measurement is required, or it can be used directly to measure indoor temperature. When used in a children's bathtub, the invention can be installed on the rim of the tub, with the temperature sensor 4 fixed to a part of the tub that comes into contact with the water, typically at the bottom. When the battery is depleted, it can be charged via a charger connected to the Type-C connector 6, making charging convenient. Compared to existing thermometers that become unusable due to battery depletion, this invention reduces operating costs, extends service life, and improves user satisfaction.

[0032] To facilitate positioning when the upper housing 1 and the lower housing 2 are connected, the lower housing 2 is provided with at least one positioning protrusion 8, and the upper housing 1 is provided with insertion holes 9 whose positions and numbers correspond one-to-one with the positioning protrusions 8. The upper housing 1 is mounted on the lower housing 2, and the positioning protrusions 8 are inserted into the insertion holes 9. In this embodiment, two positioning protrusions 8 are provided.

[0033] As can be seen from the above, the upper housing 1 and the lower housing 2 are sealed together. Specifically, the sealed connection can be achieved by ultrasonic sealing or by setting a sealing ring between the upper housing 1 and the lower housing 2 and connecting them with fasteners.

[0034] Furthermore, the sealing structure between the Type-C connector 6 and the lower housing 2 of this utility model is as follows:

[0035] One implementation involves using a sealing gasket 12 or sealant to seal the connection between the Type-C connector 6 and the lower housing 2. To ensure a good seal, the sealant is generally required to have a Shore hardness ≥80A.

[0036] In another embodiment, the Type-C connector 6 and the lower housing 2 are integrally molded by injection molding to achieve a seal. To ensure a seal, this embodiment requires that the width of the mating surface between the Type-C connector 6 and the lower housing 2 be ≥2mm. Specifically, the Type-C connector 6 is pre-placed in the mold of the lower housing 2, and the Type-C connector 6 is integrally molded with the lower housing 2 by injection molding.

[0037] It should be noted that the lower housing 2 includes a base plate and side plates surrounding the outer edge of the base plate. The upper and lower planes of the base plate both protrude upwards to form a boss 13. The socket 7 is located on the boss 13, and the Type-C connector 6 is sealed to the boss 13. The boss 13 reduces the distance between the upper housing 1 and the lower housing 2, making the structure more compact.

[0038] Furthermore, the temperature sensor 4 of this utility model is connected to the circuit board 3 via a wire 14, and a wire through hole 15 is provided on the lower housing 2. The wire 14 is sealed to the wire through hole 15 by a sealing gasket or sealant.

[0039] To improve the overall quality of the water thermometer, a decorative ring 10 is provided on the outer ring of the upper housing 1. A plug post 11 is provided on the decorative ring 10, and a corresponding insertion hole is provided on the upper housing 1. The decorative ring 10 is inserted into the insertion hole through the plug post 11 and connected to the upper housing 1, and the plug post 11 and the insertion hole are tightly fitted together.

[0040] It should be noted that the circuit board mounting base includes a first pillar 16 surrounding the circuit board 3, a first limiting post 17 at the upper end of the first pillar 16, and a groove on the circuit board 3 to avoid the first limiting post 17. The circuit board is supported on the upper surface of the first pillar 16. The size of the groove is designed according to actual conditions. Due to the groove, the circuit board can be restricted from large-scale horizontal movement within the lower housing 2. Furthermore, since the circuit board is connected to the wire 14, and the wire 14 is basically fixed after being sealed with the wire through hole 15 by a sealing gasket or sealant, the circuit board 3 will not undergo horizontal displacement. In the vertical direction, the circuit board 3 is limited by the display 4 and the first pillar 16. In addition, the shape of the upper housing 1 is basically the same as that of the lower housing 2, and it is made of light-transmitting material. The entire area of ​​the upper housing 1 is the display position. Even if the circuit board 3 moves within the housing cavity, the current temperature can still be displayed through the upper housing 1, and there will be no misalignment of the display position.

[0041] In this embodiment, the upper shell 1 and the lower shell 2 are racetrack-shaped or rectangular. The first column 16 is distributed along the side walls at both ends of the lower shell 2. A second column 18 is provided on the inner bottom surface of the lower shell 2. A second limiting column 19 is provided at the upper end of the second column 18. The second column 18 and the first column 16 distributed along the side wall at one end of the lower shell 2 form a circuit board mounting base. At this time, a racetrack-shaped or rectangular circuit board can be installed through the first column 16, and a circular, square, or other circuit board can also be installed through the second column 18 and the first column 16.

[0042] As can be seen from the above, the circuit board mounting base of this embodiment can install two different shaped circuit boards 3. When a racetrack-shaped or rectangular circuit board 3 is installed through the first column 16, a clearance hole is provided on the circuit board 3 corresponding to the position of the second limiting post 19. When the circuit board 3 is supported on the first column 16, the second limiting post 19 passes through the clearance hole without affecting the assembly of the circuit board 3. When a circular, square, or other circuit board is installed through the second column 18 and the first column 16, the circuit board 3 can be directly installed onto the circular or square mounting area enclosed by the first column 16 and the second column 18 (e.g., Figure 2 , Figure 5As shown in the diagram, no central positioning is required. Different shaped circuit boards 3 can be mounted on the same lower housing 2. Since the upper housing 1 is made of a light-transmitting material, there are no restrictions on the display area or display direction. This design facilitates different design needs of manufacturers.

[0043] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
