Abstract
Description
Technical Field
[0001] The utility model relates to a water quality testing pen with convenient battery replacement. Background Art
[0002] A battery compartment is installed on the top of the pen shell of the existing water quality test pen, and a battery compartment shrapnel is provided on the top of the circuit board inside the water quality test pen. When replacing the battery, when the battery compartment is opened or removed, the battery still remains inside the pen shell, and tools need to be used twice to remove the battery, which is inefficient and affects the customer experience. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a water quality test pen with convenient battery replacement, thereby overcoming the technical problems of troublesome operation and poor customer experience in battery replacement of existing water quality test pens.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: the water quality testing pen with convenient battery replacement includes a pen shell, a circuit board and a battery compartment are arranged inside the pen shell, a spring is arranged between the circuit board and the battery compartment, a negative electrode pad is arranged on the top of the back side of the circuit board, a positive electrode pad is arranged in the middle of the back side, a battery is arranged in the battery compartment, a positive electrode is arranged on one side of the battery, and a negative electrode is arranged on the other side of the battery, a card slot is arranged at the bottom of the battery compartment, buckles are arranged on both sides of the card slot, a positioning slot is arranged on the top of the battery compartment, a cavity is arranged inside the battery compartment, contacts are arranged at the bottom of the spring, a convex point is arranged in the middle of the spring, and a pin is arranged at the top of the spring. The battery compartment, the battery, and the spring constitute component A.
[0005] Furthermore, two symmetrical undercuts are provided on both sides of the card slot.
[0006] Furthermore, two symmetrical cavities are provided inside the battery compartment.
[0007] After adopting the above technical solution, the technical effect produced by the utility model is: the battery can be directly taken out, which facilitates the replacement of the battery and improves the customer experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0015] according to Figure 1-Figure 5 As shown, the water quality test pen with convenient battery replacement includes a pen shell 1, a circuit board 2 and a battery compartment 4 are arranged inside the pen shell 1, a spring 5 is arranged between the circuit board 2 and the battery compartment 4, a negative electrode pad 21 is arranged on the top of the back of the circuit board 2, and a positive electrode pad 22 is arranged in the middle of the back, a battery 3 is built in the battery compartment 4, a positive electrode 31 is arranged on one side of the battery 3, and a negative electrode 32 is arranged on the other side of the battery 3, a card slot 41 is arranged at the bottom of the battery compartment 4, and buckles 42 are arranged on both sides of the card slot 41, a positioning slot 43 is arranged at the top of the battery compartment 4, a cavity is arranged inside the battery compartment 4, a contact 51 is arranged at the bottom of the spring 5, and a convex point 52 is arranged in the middle of the spring 5, A pin 53 is arranged at the top of the spring sheet 5. When the pin 53 is embedded in the positioning groove 43 and the spring sheet 5 is pressed at the same time, the spring sheet 5 is snapped into the undercut 42 to position the spring sheet. By placing the positive electrode 31 of the battery 3 at the bottom of the cavity, the positive electrode 31 is in contact with the convex point 52. The battery compartment 4, the battery 3, and the spring sheet 5 form a component A. By embedding the component A into the interior of the pen housing 1, the contact 51 is in contact with the positive electrode pad 22, and the negative electrode 32 is in contact with the negative electrode pad 21, so that the circuit is turned on. When the battery needs to be replaced, the component A is taken out to replace the battery 3 in the battery compartment 4.
[0016] Preferably, two symmetrical undercuts 42 are provided on both sides of the slot 41 .
[0017] Preferably, two symmetrical cavities are provided inside the battery compartment 4.
