[0026] The backrest 3 includes a front shell 31 and a rear cover 32. The elastic locking mechanism 4 is symmetrically arranged at the edges of the inner bottom surface of the front shell 31. The bottom of the front shell 31 is provided with an integrated side positioning sleeve 311 and a center positioning sleeve 313. The center positioning sleeve 313 is provided with an upper power connector 6 and an upper water connection sleeve 5 (see Figure 4), the upper electrical connector 6 is connected to the circuit board in the backrest 3, and the connection between the upper electrical connector 6 and the lower electrical connector 8 is respectively provided with a pin and a slot for matching. The upper water connection sleeve 5 is installed in the middle of the bottom surface of the front shell 31 through the positioning plate 51. The upper water connection sleeve 5 and the positioning plate 51 are integrally formed. The upper end of the upper water connection sleeve 5 is connected to the water pipe 7 in the front shell 31, and the lower end of the upper water connection sleeve 5 extends into the center positioning sleeve 313. The groove 52 processed in the middle of the positioning plate 51 penetrates the center positioning sleeve 313, and the upper electrical connector 6 is arranged in the groove 52 (see Figure 7 );

[0027] The elastic locking mechanism 4 includes a guide seat 41 fixed to the front shell 31, a slider 42 slidingly arranged in a guide groove 411 of the guide seat 41, the end of the guide groove 411 close to the side wall of the front shell 31 is a closed end, a compression spring 43 is installed between the slider 42 and the closed end of the guide groove 411, and a locking block 421 is integrally arranged at the bottom of the slider 42 (see Figure 6 ), the locking block 421 extends into the side positioning sleeve 311, the locking block 421 is L-shaped, the hook portion 423 at the lower portion of the locking block 421 is embedded in the notch 312, and a toggle block 422 is provided on the side of the slider 42 facing the rear cover 32. Square holes 321 are symmetrically processed on both sides of the lower portion of the rear cover 32. The ends of the toggle blocks 422 extend along the square holes 321. The length of the square holes 321 matches the length of the toggle track of the toggle blocks 422. A recessed portion 322 is formed at the edges of the two square holes 321 facing each other.

[0028] The side positioning sleeve 311 and the center positioning sleeve 313 are correspondingly inserted into the side positioning groove 21 and the center positioning groove 23. The locking block 421 of the elastic locking mechanism 4 extends along the notch 312 on the side wall of the side positioning sleeve 311 and is inserted into the locking groove 22 to achieve the fixation of the backrest 3 and the storage table 2. An electrical connection and a water connection are formed between the lower electrical connector 8 and the upper electrical connector 6, and between the lower water connection sleeve 9 and the upper water connection sleeve 5, respectively.

[0029] In the tea bar machine structure, side positioning sleeves and a center positioning sleeve are provided on the backrest, and side positioning grooves and a center positioning groove are provided on the storage table, so that the backrest and the storage table are accurately positioned. An elastic locking mechanism is installed on the inner bottom surface of the backrest at a position corresponding to the side positioning sleeve. The locking block in the elastic locking mechanism extends into the side positioning sleeve and can be radially shifted. After the backrest and the storage table are plugged in, the hook portion of the elastic locking mechanism extends along the notch on the side wall of the side positioning sleeve and is inserted into the locking groove by the elastic force of the compression spring to fix the backrest and the storage table; a lower electrical connector and a lower water channel connecting sleeve are provided in the center positioning groove of the storage table, and an upper electrical connector and an upper water channel connecting sleeve are provided in the center positioning sleeve of the backrest.
