Description

Technical Field

[0001] The utility model relates to the field of timer devices, in particular to a split timer. Background Art

[0002] With the development of technology and the improvement of people's living standards, timers, as a common time management tool, are becoming increasingly widely used. Traditional timers mostly adopt an integrated design, where the dial assembly and movement assembly are enclosed in the same housing. While this structure ensures the product's compactness and aesthetics to a certain extent, it also has some obvious shortcomings, which are generally included as follows:

[0003] (1) Complex assembly process: In the traditional integrated timer production process, the dial assembly and the movement assembly often need to be assembled on the same assembly line, which requires workers to have high operating skills and increases the complexity of the production process. Since the dial assembly and the movement assembly usually have delicate structures, the connection and calibration between them require highly precise operations. This not only increases the workload on the production line, but may also lead to a decrease in production efficiency. The complex assembly process may also increase the risk of product defects and affect product quality and reliability.

[0004] (2) High after-sales costs: When the production and sales locations are different, due to regional temperature changes or other external factors, when a product malfunctions, the entire timer often needs to be returned for repair or replacement, which not only increases the cost of after-sales service but also affects the user experience. For example, under some extreme climatic conditions, the material may expand or contract, causing internal parts to loosen or become damaged. If this happens, the user may need to send the entire timer back to the manufacturer for repair or replacement, which is not only time-consuming but also expensive. In addition, the risk of damage during transportation will also increase after-sales costs.

[0005] (3) Lack of space for personalization: As young people are increasingly demanding personalized and customized products, timers are commonly used time management devices. Traditional integrated timers often have a fixed design appearance during design. In addition, their highly integrated design structure makes it difficult and challenging for users to DIY style their products after purchase, while purchasing them separately is not economical.

[0006] Therefore, if the structure of the timer can be optimized and designed in a modular form, for example, the dial and movement parts adopt a split structure, it will not only improve the independence and flexibility during production and installation, but also provide greater convenience and economy for the user experience and maintenance, which has positive practical significance for the use, sales, promotion and production of the product.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are merely partial embodiments of the present invention and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0043] Example 1

[0044] Combine Figures 1 to 4 As shown in one of the figures, the present embodiment provides a split timer, comprising a movement 1, a dial 2, an indicator 4 and a housing 3, wherein the housing 3 comprises a first shell 31 and a second shell 32, the movement 1 being arranged in the first shell 31, and having a driving rod 11 exposed from the first shell 31, the driving rod 11 being a driving portion for outputting driving force when the movement 1 is working; the dial 2 and the indicator 4 being arranged in the second shell 32, one end face of the first shell 31 being opposite to one end face of the second shell 32 and being detachably fixedly connected, the driving rod 11 being connected to the indicator 4 through a connecting piece, and the indicator 4 being driven by the movement 1 to rotate relative to the dial 2 through the driving rod 11.

[0045] In the implementation structure of the first shell 31 , in this embodiment, a first avoidance hole 311 is provided on one end surface of the first shell 31 to expose the driving rod 11 .

[0046] In this solution, the indicator 4 is used to indicate the timing duration of the timer. The connecting member is a rotating shaft 6. The indicator 4 is rotatably connected to the second shell 32 through the rotating shaft 6. One end of the rotating shaft 6 is rotatably inserted into the second shell 32 from the middle of one end surface of the second shell 32. The indicator 4 is fixedly connected to the rotating shaft 6. The other end of the rotating shaft 6 is cooperatively connected with the driving rod 11 of the movement 1. The movement 1 drives the rotating shaft 6 through the driving rod 11 to drive the indicator 4 to rotate relative to the dial 2.

[0047] Accordingly, as a preferred embodiment of the second shell 32, preferably, the second shell 32 of this solution is provided with a second avoidance hole 321 for the rotation shaft 6 to pass through, and the rotation shaft 6 can be rotatably connected to the second shell 32 through a rotating member or a rotation limit member; focus on Figure 4 In this embodiment, as an example, the rotation limiter can be a pair of retaining springs 62, which are detachably connected to the two sides of the rod of the rotating shaft 6 passing through the second avoidance hole 321, so that the rotating shaft 6 is rotationally constrained on the second shell 32; if a rotating member is used, the rotating shaft 6 can be rotationally connected to the second shell 32 through a rotating connecting sleeve or a rotating shaft.

[0048] In the implementation structure of the second shell 32, a glass cover 322 is provided on the other end face of the second shell 32 of this solution. The user can clearly see the timing on the dial 2 through the glass cover 322, and at the same time, the glass cover 322 can prevent foreign objects from falling into the second shell 32.

[0049] Focus on combination Figure 2 、 Figure 3 or Figure 4 As shown, regarding the connection between the rotating shaft 6 and the movement 1, as a preferred embodiment, the other end of the rotating shaft 6 is preferably engaged with the driving rod 11 of the movement 1; specifically, as a structural example, preferably, the end of the driving rod 11 is provided with a tongue 111, and the other end of the rotating shaft 6 is provided with a slot 61 that engages with the tongue 111. However, this embodiment is not limited to this, and the end of the driving rod may also be provided with a slot, and the other end of the rotating shaft may be provided with a tongue that engages with the slot.

[0050] In addition to the above, the split-type timer described in this solution also includes a knob 7, which is connected to the movement 1 for adjusting the timer duration. In this embodiment, one end of the shaft 6 extends axially and rotatably passes through the other end surface of the second housing 32 and is fixedly connected to the knob 7. The rotation of the knob 7 drives the shaft 6 to pull the movement 1 to adjust the timer duration. Among them, adjusting the timer duration through the front knob 7 is already a relatively common timer setting structure currently, and this solution will not be repeated here.

[0051] In the detachable implementation form between the first shell 31 and the second shell 32 , in this embodiment, one end surface of the first shell 31 is opposite to one end surface of the second shell 32 and they are detachably fixedly connected via the plug-in structure 5 .

[0052] As one of the implementation forms of the plug-in structure, further, the plug-in structure described in this embodiment includes a protrusion 5A and a sinking portion 5B adapted to the contour of the protrusion 5A; specifically, the protrusion 5A described in this embodiment is arranged on one end face of the second shell 32, which is an annular structure and is located on the outer peripheral side of the second shell 32, and the sinking portion 5B is also an annular structure, which is arranged on the outer peripheral side of one end face of the first shell 31, and is used to cooperate with the protrusion 5A to form a plug-in structure 5, so as to detachably and fixedly connect the first shell 31 and the second shell 32.

[0053] The positions of the raised portion 5A and the sunken portion 5B of the plug-in structure 5 described in this solution may not be limited to this embodiment. As another positional arrangement implementation form of the raised portion and the sunken portion, the raised portion described in this solution may also be arranged on one end face of the first shell, and the sunken portion may be correspondingly arranged on one end face of the second shell, and is used to cooperate with the raised portion to form a plug-in structure, so as to detachably and fixedly connect the first shell and the second shell.

[0054] This solution cleverly arranges the timer housing 3 into a split first housing 31 and a second housing 32, arranges the movement 1 in the first housing 31, and arranges the dial 2, indicator 4 and other components in the second housing 32. Through the detachable connection of the first housing 31 and the second housing 32, the first housing 31 and the second housing 32 can be assembled separately during the factory production stage, and the second housing 32 and the dial 2, indicator 4 and other components can be assembled separately. When the timer is finally used, it is only necessary to simply detachably assemble the first housing 31 and the second housing 32. The driving rod 11 of the movement 1 is synchronously connected with the rotating shaft 6 to realize the functional assembly of the timer. Under this structural form, the manufacturer can assemble and distribute components more flexibly, and the after-sales party can replace the module formed by the first shell 31 or the second shell 32 separately according to the specific damaged location of the component during use by the user. In addition, the manufacturer can also design the second shell 32 with different appearances according to actual needs for consumers to purchase in a modular manner, thereby improving their consumption experience; at the same time, the versatility of the component modules can also reduce costs to a certain extent during replacement and maintenance, and provide more opportunities for the reuse of available components.

[0057] In this embodiment, the plug-in structure 5 includes a raised portion 5A and a depressed portion 5B that matches the contour of the raised portion 5A. The raised portion 5A is provided on one end surface of the second housing 32 and is an annular structure located in the middle of one end surface of the second housing 32, i.e., in an area near the rotating shaft 6. The depressed portion 5B is provided in the middle of one end surface of the first housing 31 and corresponds to an annular groove. It is used to cooperate with the raised portion 5A to form a plug-in structure, thereby removably and fixedly connecting the first and second housings 31, 32. The slot 61 of the rotating shaft 6 and the tongue 111 of the drive rod 11 can be assembled and aligned before the first and second housings 31, 32 are aligned. After that, they can be synchronously assembled and installed when the first and second housings 31, 32 are removably and fixedly connected.

[0061] In this embodiment, the raised portion 5A is a discontinuous annular structure, which is composed of a plurality of protrusions arranged in an annular array, and the sunken portion 5B is correspondingly composed of a plurality of grooves arranged in an annular array; similarly, the slot 61 of the rotating shaft 6 and the tongue 111 of the driving rod 11 can be assembled and aligned before the first shell 31 and the second shell 32 are aligned and assembled, and then synchronously matched and installed in place when the first shell 31 and the second shell 32 are detachably fixedly connected.

The sunken portion 5B is correspondingly provided at the middle of one end surface of the first shell 31 and is composed of a plurality of grooves arranged in a ring array. Similarly, the slot 61 of the rotating shaft 6 and the tongue 111 of the driving rod 11 can be assembled and aligned before the first shell 31 and the second shell 32 are aligned and assembled, and then synchronously matched and installed in place when the first shell 31 and the second shell 32 are detachably fixedly connected.

[0069] In this embodiment, the adsorption assembly 8 includes a first adsorption component 8A and a second adsorption component 8B. There are more than one first adsorption component 8A (two in this embodiment, and they are arranged opposite to each other), which are arranged on one end face of the first shell 31. The number of the second adsorption components 8B corresponds to the number of the first adsorption components 8A, which is more than one (two in this embodiment, and they are arranged opposite to each other). They are arranged on one end face of the second shell 32, and their positions correspond one to one; the first adsorption component 8A and the second adsorption component 8B are adsorbed and matched to detachably and fixedly connect the first shell 31 and the second shell 32.

[0070] In terms of specific configuration, in this embodiment, the first adsorption member 8A is embedded in one end surface of the first shell 31, and the second adsorption member 8B is embedded in one end surface of the second shell 32. Of course, the configuration is not limited to embedded configuration.
