Detailed ways

As shown in Figures 1 to 13, the present invention includes a housing 1, an upper cover 2, a base 3, an outer bladder 4, an ultraviolet lamp, a conical frame 6, a heater 32, a support plate 7 and a baffle 8, and the following is combined with the attached The figures describe the invention.

As shown in Fig. 1 and Fig. 2, the housing 1 is the main body of the present invention, and the housing is tapered with a small top and a large bottom, and has a curved shape. The bottom of the housing is provided with a base 3, and a circular fixed cylinder 31 is arranged on the base. The role of the fixed cylinder is to support and install other components, and the seal between the fixed cylinder and the base is good. The base is provided with a power interface electrically connected to the 220V AC power supply, and a heater 32 is provided in the center of the upper part of the base. The heater is electrically connected to the power interface through wires. Can be heated. In order to control the working state of the heater, a first switch 11 and a second switch 12 are provided on the outer wall of the housing. The second switch is a timing switch for controlling the working state and working time of the heater.

A loam cake 2 is arranged on the top of the housing, and a limiting plate 22 is connected to the bottom of the loam cake by clamping 21. The limiting plate is an annular metal plate or plastic plate, and the limiting plate is threadedly connected with the housing. The bottom of the limiting plate is fixed with an inner container 23, which is a cylindrical glass piece, and the outer wall of the inner container is aligned up and down with the outer wall of the limiting plate. The bottom of the liner is provided with a support plate 7, the support plate is a circular plastic plate or glass plate, as shown in Figure 4, the top of the support plate is provided with some limit holes 71, the limit holes are circular holes, such as As shown in Fig. 13, the limiting holes on the same circumference along the circumferential direction are arranged at equal intervals, and several limiting holes are distributed radially along the radial direction. The limiting holes are arranged in multiple circles. Looking from the inner ring to the outer ring, the limiting holes of the outer ring are always more than the limiting holes of the inner ring. After the chopsticks are placed in the inner container, the lower end of the chopsticks is against the limiting hole. The effect of the limiting hole is to limit the movement of the chopsticks, and another function of the limiting hole is to collect water. Between every two adjacent limiting holes is a dividing plate 72, in order to connect all the limiting holes together, a transverse through hole 721 is provided at the bottom of each dividing plate, so that the limiting holes at the two ends of the dividing plate connected together. In this way, the water on the chopsticks inserted in the limiting holes of the outer ring slides down along the chopsticks and deposits in the corresponding limiting holes. More and gradually flow to the limit hole of the innermost ring 10.

A water flow channel 73 is provided below each limiting hole of the innermost ring, and the water flow channel runs through the lower surface of the support plate, and the accumulated water in the limiting holes of the innermost ring 10 can flow down through the water flow channel. Several transverse passages 74 are arranged on the support plate, and the several transverse passages communicate with corresponding water flow passages and are vertical. Also be provided with some vertical vertical passages 75 on the support plate, several vertical passages communicate with the corresponding horizontal passages, as shown in Figure 10, the water flow passage forms an "h" shape with the horizontal passages and the vertical passages, and the vertical passages The airflow channel is formed by the vertical channel and the horizontal channel. The vertical channel is located above the heater. The heater heats up the surrounding air. As shown in Figure 12, the hot air enters the horizontal channel through the vertical channel and then rises through the water flow channel. And pass through the chopsticks to dry the chopsticks. Part of the hot air can also rise through the water flow channel and pass through the chopsticks to achieve a drying effect.

A tapered hollow baffle 8 is arranged between the support plate and the heater, the large end of the baffle faces downwards, the small end of the baffle faces upwards, and the tapered surface of the baffle is located directly below the water flow channel. The center of the small end is provided with a hot air rising port 81, and the water droplets falling through the water flow channel can slide down along the tapered surface of the baffle plate without flowing on the heater through the hot air rising port and damaging the heater.

An outer container 4 is arranged between the fixed cylinder and the inner container. The outer container has the function of heat preservation, and the outer container is fixed on the inner surface of the fixed container. stable thermal environment. In order to realize the sterilization and disinfection of chopsticks, an annular first ultraviolet lamp 51 is arranged on the upper part of the outer bladder, and an annular second ultraviolet lamp 52 is arranged on the lower part of the outer bladder, and a ring-shaped ultraviolet lamp 52 is arranged on the corresponding position on the outer bladder. Groove, so that the first ultraviolet lamp and the second ultraviolet lamp are buried in the outer bladder, so that the inner bladder and the outer bladder are closely attached to avoid the inner tank. The upper cover, inner tank and limiting plate can be taken out from the outer tank for easy cleaning and replacement. The function of the limiting plate is to limit the position of the inner container, so as to prevent the inner container from colliding with the outer container and causing breakage.

In order to prevent the chopsticks from being scattered in the inner container, a conical frame 6 is provided in the inner cavity of the inner container. The conical frame is a tapered plastic part, as shown in Fig. 5, Fig. 6 and Fig. 7. It is an annular mounting end 61, and the tapered frame is fixed on the inner wall of the liner through the mounting end. The other end of the tapered frame is the clamping end 62, and the clamping end is provided with several bar-shaped gaps 622 uniformly arranged along the circumference. Strips are elastic. As shown in Figure 3, when the tapered frame is placed inside the liner, the large end of the tapered frame faces upward and the small end faces downward. After putting the chopsticks in the tapered frame, as shown in Figure 8, as the number of chopsticks increases, the chopsticks will gradually expand the small end of the tapered frame, and the clips on the tapered frame will react against the chopsticks and clamp the chopsticks tightly. Prevent chopsticks from falling apart. The bottom of chopsticks is limited to the little end of tapered frame, and the top of chopsticks 9 separates from each other and makes some chopsticks become the taper shape of up and down, and chopsticks are separated from each other, which is more conducive to the drying of chopsticks.

As shown in FIG. 11 , the number of airflow passages can also be two. At this time, the transverse passages of the two airflow passages are connected end to end, and the two airflow passages form a flat "F" shape. When the power of the heater is high, the hot air can enter the horizontal passage through multiple vertical passages, so as to avoid excessive pressure caused by accumulation of hot air between the heater and the support plate. The first switch forms a closed current loop with the first ultraviolet lamp and the second ultraviolet lamp, and is used to control the working condition of the ultraviolet lamp.
