Description

Technical Field

[0001] The utility model relates to the field of timers, in particular to the field of timers with the function of displaying characters by LED lights. 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 safety hazard of electric shock. At the same time, due to the high hardness of stainless steel materials, 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. At the same time, at present, the widespread use of LED lights for energy conservation is the mainstream. If the light emitted by the LED lights can penetrate through the character windows to achieve the effect of character display, it will undoubtedly greatly reduce costs and save energy. Since the common timers on the market have metal shells, it is usually inconvenient to set up a support frame. 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. Summary of the Utility Model

[0003] In order to solve the above problems, the utility model provides a timer with LED lights for displaying characters, 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 character light-transmitting window is also arranged on the upper end surface of the front shell. Regularly arranged LED lights and small micro switches are arranged on the upper end surface of the circuit board. Multiple LED lights and small micro switches can be set, and the number depends on the functional requirements. The LED lights are arranged corresponding to the character light-transmitting windows. The light emitted by the LED lights forms bright timing or counting characters after passing through the character light-transmitting windows. There is a spatial distance between the bottom end surface of the character light-transmitting window and the LED lights.

[0004] Preferably, the distance between the bottom end surface of the character light-transmitting window and the LED lights is 3-6 mm.

[0005] Further, at each end of the bottom end surface of the bottom case, at least one support foot structure with an adjustable angle is provided. The support foot structure includes a support frame and a support seat portion of the bottom case. The support frame is installed in the shaft holes of the support seat portion with shafts on both sides, and the support piece is movably positioned in the positioning groove of the positioning piece of the support seat portion. When the support frame moves up and down at different angles, different angle support shapes are formed with the bottom case; a buckle piece is provided at one end of the support seat portion 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 end of the buckle piece. A concave pit for buckling with the buckle piece is provided on the inner wall of the reinforcing rib on the inner wall of the support frame. When the convex block cooperates with the concave pit, the loosening of the support frame on the bottom case can be effectively prevented.

[0006] Further, a charging base and a power cord inlet hole are also provided on the side of the combined case. The charging base can insert the charging end of the charger. The power cord inlet is the part where the power cord enters the case. A power cord fixing seat is provided on the inner end surface 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 surface of the bottom case. The wall hanging holes can insert nails fixed on the wall to hang the timer on the wall.

[0007] Further, a speaker and a buzzer are also provided on the inner end surface of the bottom case. The speaker is fixed in the speaker seat on the inner end surface 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 being easily 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. Pressing the operation interface film at the position of the elastic button can perform function operations.

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

[0011] Further, the circuit board, the speaker, the buzzer, and the charging base are electrically connected.

[0012] The working principle and features of the present utility model are as follows: After the power supply is turned on, the operator can perform functional operations on the small micro switch below at the elastic button for film sticking on the operation interface. When the LED light is on under the operation of the program function of the circuit board, the light passes through the character light-transmitting window to display 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 status. When it is necessary to place the timer obliquely, the support frame is pulled open to support the bottom shell on the table at a certain angle. When it needs to be hung on the wall, it can also be hung on the nail on the wall through the wall hanging hole. The timer uses a small micro switch as an electrical component, which can save more costs than the large micro switches used in the same type of products on the market. At the same time, using plastic material as the shell also reduces costs and adds the function of relevant support feet. Brief Description of the Drawings

[0020] As Figures 1 - 6As shown in the figure, the present utility model will be further described in detail by way of embodiments: The present utility model discloses a timer with LED lights for displaying characters, which includes a front shell 4 and a bottom shell 1. A circuit board 3 is arranged in the cavity of the combined shell formed after the front shell 4 and the bottom shell 1 are assembled. An elastic button 41 is arranged on the upper end surface of the front shell 4. The elastic button 41 is formed by hollowing out a part of the top surface of the front shell 4 to form a suspended shape. The suspended part forms elasticity with its root. Pressing the suspended position can press the micro switch 31 on the circuit board 3. A character light-transmitting window 42 is also arranged on the upper end surface of the front shell 4. Regularly arranged LED lights 32 and small micro switches 31 are arranged on the upper end surface of the circuit board 3. The number of LED lights 32 and small micro switches 31 can be multiple, depending on the functional requirements. The LED lights 32 are arranged corresponding to the character light-transmitting windows 42. The light emitted by the LED lights 32 forms bright timing or counting characters after passing through the character light-transmitting windows 42. There is a space distance between the bottom end surface of the character light-transmitting window 42 and the LED lights 32. Having a space distance is more conducive to better outward irradiation of the light.

[0021] Preferably, the distance between the bottom end of the character light-transmitting window 42 and the LED lights 32 is 3-6 mm. The space distance of 3-6 mm is the best distance for light irradiation.

[0022] In this embodiment, at least one adjustable-angle support foot structure is arranged at both ends of the bottom end surface of the bottom shell 1. The support foot structure includes a support frame 2 and a support seat part 11 of the bottom shell 1. The support frame 2 is installed in the shaft hole 101 of the support seat part 11 with shafts 203 on both sides. The support piece 202 is movably positioned with the positioning groove 1021 on the positioning piece 102. When the support frame 2 moves up and down at different angles, different-angle support shapes are formed with the bottom shell 1. A buckle piece 103 is arranged at one end of the support seat part 11 away from the positioning piece 102. The buckle piece 103 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 103. A concave pit for buckling with the buckle piece 103 is arranged on the inner wall of the reinforcing rib 205 of the inner wall 201 of the support frame 2. When the convex block cooperates with the concave pit, the loosening of the support frame 2 on the bottom shell 1 can be effectively prevented. In this embodiment, the reinforcing rib 205 on the support frame 2 is provided with a concave pit buckling structure for buckling with the buckle piece 103, or it can be replaced by an interference fit between the buckle piece 103 and the inner wall of the reinforcing rib 205 on the support frame 2. When they are close to each other, frictional force is generated by the interference between them to achieve the effect of buckling and not loosening.

[0023] In this embodiment, a charging socket 6 and a power cord inlet hole are also arranged on the side of the combined shell. The charging socket 6 can insert the charging end of the charger. The power cord inlet is the part where the power cord enters the shell.

[0024] In this embodiment, a power cord fixing seat 7 is provided on the inner end face of the bottom case 1. A pressing piece is installed on the fixing seat 7 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 1, and the wall hanging holes can facilitate hanging the timer on the wall.

[0025] In this embodiment, a speaker 9 and a buzzer 8 are also provided on the inner end face of the bottom case 1. The speaker 9 is fixed in the speaker seat on the inner end face of the bottom case. The edge of the speaker 9 and the speaker seat are fixed with fixing glue. The buzzer 8 is fixed to the support ring with fixing glue. The support ring has an inner cavity, and there are evenly distributed small through holes at the bottom of the inner cavity. The sound emitted by the buzzer 8 diffuses out through the small through holes, which is beneficial to improving the volume and being easily perceived.

[0026] In this embodiment, the inner diameter of the copper outer ring part 81 of the buzzer 8 is larger than the outer diameter of the buzzer support ring. When the copper outer ring part 81 of the buzzer 8 is suspended outside the support ring, when the buzzer 8 is powered on and operates, the amplitude of vibration of the copper outer ring part 81 will be larger, and the sound emitted will also be larger.

[0027] In this embodiment, an operation interface film 5 is also provided on the upper part of the front case 4. Pressing the operation interface film 5 at the position of the elastic button 41 can perform function operations.

[0028] Preferably, the material of the combined case is plastic, which can effectively reduce costs and add related functions designed due to the plastic material.
