[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This utility model provides a weighing module with a spherical pressure head structure, such as Figure 1 As shown, the device includes a base 1; the base 1 is provided with a support component 2 for supporting the object to be weighed and a weighing component 3 with a spherical pressure head structure; the support component 2 is detachably connected to the base 1; the weighing component 3 is detachably connected to the base 1; the support component 2 is provided with a weighing groove 4; the weighing end of the weighing component 3 is placed in the weighing groove 4 and abuts against the inner wall of the weighing groove 4.

[0024] Specifically, by setting the weighing module on the weighing device or using it directly, the object to be weighed is placed on the support component 2, and the weighing component 3 with a spherical pressure head structure weighs the object on the support component. Because of the use of the spherical pressure head, the error caused by the object not being placed in the center of the weighing area can be reduced, further improving the weighing accuracy.

[0025] Further, the weighing assembly 3 includes: a mounting base 31, a weighing sensor base 32, and a spherical weighing head 33; the mounting base 31 is detachably connected to the device base 1; one end of the weighing sensor base 32 is detachably connected to the mounting base 31; one end of the spherical weighing head 33 is detachably connected to the other end of the weighing sensor base 32, and the other end is placed in the weighing groove 4 and abuts against the inner wall of the weighing groove 4; an electrosensitive diaphragm is provided on the end of the weighing sensor base 32 near the spherical weighing head 33; one end of the spherical weighing head 33 can abut against the electrosensitive diaphragm.

[0026] Specifically, the weighing sensor base 32 is mounted on the device base 1 via the mounting base 31. The spherical weighing head 33 abuts against the inner wall of the weighing tank 4, thereby transmitting the weighing pressure to the spherical weighing head 33, converting the force signal into an electrical signal, and then transmitting the electrical signal to the inductive diaphragm to the external receiving device, thereby achieving the effect of weighing the weight data of the object.

[0027] Furthermore, the spherical weighing head 33 includes: a spherical contact head 331 and a sensing element 332; the spherical contact head 331 can be housed in the weighing groove 4 and abuts against the inner wall of the weighing groove 4; one end of the spherical contact head 331 is fixedly connected to the sensing element 332; the other end of the sensing element 332 is detachably connected to the weighing sensing base 32 and can abut against the inductive diaphragm.

[0028] Specifically, the sensor 332 has a hollow structure with a conductive line inside the hollow cavity. The spherical contact head 331 is provided with piezoelectric material. The pressure is transmitted to the piezoelectric material on the spherical contact head 331 through the weighing object on the supporting component 2. After being converted into an electrical signal, the electrical signal is transmitted to the inductive diaphragm through the conductive line, thereby realizing the effect of transmitting the weighing data.

[0029] Furthermore, a data terminal line 34 is embedded in the weighing sensor base 32; one end of the data terminal line 34 is electrically connected to the inductive diaphragm, and the other end passes through the inner wall of the weighing sensor base 32 and is electrically connected to an external receiving component to transmit weighing data.

[0030] Specifically, after the electrosensitive diaphragm receives the electrical signal, it transmits the electrical signal to the external data receiving device through the data terminal line 34, thereby achieving the effect of visual transmission of weighing data.

[0031] Furthermore, the mounting base 31 is also provided with a step-proof baffle 35 for protecting the data terminal line 34.

[0032] Specifically, the anti-stepping baffle 35 can effectively prevent the data terminal cable 34 from being damaged by people stepping on it during use, further improving scene adaptability and service life.

[0033] Further, the supporting component 2 includes: a supporting base plate 21, a U-shaped support seat 22, and a supporting plate 23; the supporting base plate 21 is detachably connected to the mounting base 31; one end of the U-shaped support seat 22 is detachably connected to the supporting base plate 21; the supporting plate 23 is detachably connected to the other end of the U-shaped support seat 22; the weighing groove 4 is opened at the center of the supporting plate 23; the U-shaped support seat 22 and the supporting plate 23 cooperate to form a receiving area 24 for receiving the weighing end of the weighing component 3.

[0034] Specifically, a fixed area is provided on the device base 1 through the support base plate 21, the U-shaped support seat 22 is placed on the support base plate 21, and then the support plate 23 is placed on the U-shaped support seat 22 to form an overall support frame. The weighing object is placed on the support plate 23 to achieve the effect of support and weighing. The support plate 23 is provided with a weighing groove 4. The setting of the weighing groove 4 is different from the traditional setting. The weighing groove 4 is a through groove, which allows the weighing component 3 of the spherical pressure head structure to receive pressure from different angles, thereby realizing the use of more application scenarios and the weighing accuracy is higher.

[0035] Specifically, the weighing component 3 can be placed in the storage area 24 formed by the U-shaped support 22 and the support plate 23, so that the connection between the weighing end of the weighing component 3 and the support plate 23 is at the center of the support plate 23, thereby further improving the weighing accuracy.

[0036] Furthermore, it also includes a reinforcement member 25 for strengthening the overall support strength; one end of the reinforcement member 25 abuts against the U-shaped support seat 22, and the other end passes through the U-shaped support seat 22 and the support base plate 21 in sequence and is detachably connected to the device base 1.

[0037] Specifically, the reinforcement 25 makes the overall support strength higher, and will not cause the U-shaped support 22 to fall off the device base 1 due to external factors or other circumstances.

[0038] Furthermore, a ground wire 5 is also provided on the support plate 23; one end of the ground wire 5 is detachably connected to the support plate 23, and the other end is detachably connected to the device base 1.

[0039] Specifically, through the ground wire 5, if leakage occurs on the support plate 23 during the weighing process, the current will be conducted to the ground to prevent the weighing component 3 from being damaged due to leakage, thereby further improving the adaptability of the scenario.

[0040] This utility model discloses a weighing module with a spherical pressure head structure. The weighing component 3 with a spherical weighing head 33 can effectively cooperate with the support component 2 with a weighing groove 4 to achieve accurate measurement of the object to be weighed in different positions. The spherical weighing head 33 can quickly and accurately sense the weighing signal at different incident angles and then accurately transmit the signal to the diaphragm, which greatly reduces the error during measurement, improves the accuracy and consistency of the sensor, and further improves the weighing accuracy.
