Description

Technical Field

[0001] The utility model relates to the field of timers, in particular to the field of commercial timers with a support foot structure. Background Art

[0002] Among the common timers or counters on the market, most are made of stainless steel shells. When encountering water mist or humid weather, it is easy to cause short circuits and electric leakage. If the human body touches the metal shell, there will be a potential safety hazard of electric shock. At the same time, due to the high hardness of the stainless steel material, when using a micro switch for circuit function operation, a larger micro switch is required for operation because the mask has no concave-convex surface and is only made into a flat surface, thus forming a flat surface with the button. Such a design results in extremely poor button-pressing feel, making it inconvenient for users to use. This not only has a high material cost but also is not conducive to setting a support frame on the rear shell. When there is a need to place the timer obliquely, it does not have a support frame that can adjust the angle, bringing many inconveniences to the actual use of the timer. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a timer with a digital tube, which includes a front shell and a bottom shell. A circuit board is arranged in the cavity of the combined shell formed after the front shell and the bottom shell are assembled. An elastic button is arranged on the upper end surface of the front shell. The elastic button is formed by hollowing out a part of the top surface of the front shell to form a suspended shape, and the suspended part forms elasticity with its root. A digital tube and a small micro switch are arranged on the upper end surface of the circuit board. Multiple digital tubes and small micro switches can be arranged, and the quantity depends on the functional requirements. At least one support foot structure with adjustable angle is arranged at each end of the bottom end surface of the bottom shell.

[0004] Furthermore, the support foot structure includes a support frame and a support seat part of the bottom shell. The support frame is installed in the shaft holes of the support seat part with shafts on both sides, and the support piece can be movably positioned in the positioning groove of the positioning piece of the support seat part. When the support frame moves up and down at different angles, different angle support shapes are formed with the bottom shell; a buckle piece is arranged at one end of the support seat part away from the positioning piece, and the buckle piece is provided with an elastic buckle structure. The elastic buckle structure is a convex block slightly protruding on the end surface of the buckle piece. A concave pit for buckling with the buckle piece is arranged on the inner wall of the reinforcing rib on the upper inner wall of the support frame. When the convex block cooperates with the concave pit, the loosening of the support frame on the bottom shell can be effectively prevented.

[0005] Furthermore, a charging seat and a power cord inlet hole are also arranged on the side of the combined shell. The charging seat can insert the charging end of the charger, and the power cord inlet is the part where the power cord enters the shell.

[0006] Further, a power cord fixing seat is provided on the inner end face of the bottom case to fix the power cord and prevent it from moving. Two wall hanging holes are symmetrically distributed on the outer end face of the bottom case, and the wall hanging holes can facilitate hanging the timer on the wall.

[0007] Further, a speaker and a buzzer are also provided on the inner end face of the bottom case. The speaker is fixed in the speaker seat on the inner end face of the bottom case, and the edge of the speaker is fixed to the speaker seat with fixing glue. The buzzer is fixed on the support ring. The support ring has an inner cavity, and small through holes are evenly distributed at the bottom of the inner cavity. The sound emitted by the buzzer diffuses out through the small through holes, which is beneficial to increasing the volume and making it easier to be perceived.

[0008] Further, the inner diameter of the copper outer ring part of the buzzer is larger than the outer diameter of the buzzer support ring. When the copper outer ring part of the buzzer is suspended outside the support ring, when the buzzer is powered on and operates, the vibration amplitude of the copper part will be greater, and the sound emitted will also be greater.

[0009] Further, an operation interface film is also provided on the upper part of the front case. Press the operation interface film at the position of the elastic button to perform function operations.

[0010] Preferably, the material of the housing is plastic, which can effectively reduce costs and add related functions designed due to the plastic material.

[0011] Further, the circuit board is electrically connected to the speaker, the buzzer, and the charging seat.

[0012] The working principle and features of the present utility model are as follows: When the power is turned on, the operator can perform function operations on the small micro switch below at the elastic button of the operation interface film. Under the operation of the program function of the circuit board, the digital tube displays the relevant timing or counting status of the timer. When the set value of timing or counting is reached, the buzzer emits a warning sound, and the speaker can also give relevant voice prompts for function settings or warning states. When it is necessary to place the timer obliquely, the support frame is pulled open to support the bottom case on the tabletop at a certain angle. When it is necessary to hang it on the wall, it can also be hung on the nail on the wall with the wall hanging hole. The timer uses a small micro switch as an electrical component, which can save more costs than the large micro switch used in the same type of products on the market. At the same time, using plastic material as the housing also reduces costs and adds related support foot functions. BRIEF DESCRIPTION OF THE DRAWINGS
