DETAILED DESCRIPTION

[0022] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an embodiment of the utility model provides a liquid quantitative control device, including: a shell assembly 1, on which a discharge shell 2, a motor 3, and a second gear 4 are fixedly installed, the output end of the motor 3 is fixedly installed with a first gear 6 meshing with the second gear 4, the internal thread of the second gear 4 is fitted with a sliding shell 7 that is slidably fitted with the shell assembly 1, a float 8 is placed on the top of the sliding shell 7, an electric push rod 9 is fixedly installed on the lower side of the discharge shell 2, and two sealing sheets 10 are fixedly installed on the output end of the electric push rod 9, and the shell assembly 1 includes a first shell 11 and a second shell 12 fixedly mounted with the first shell 11.

[0025] In this embodiment, specifically: a connecting piece 13 is fixedly mounted on the upper surface of the second housing 12 , and two first sealing rings 13 corresponding to the first housing 11 and the second housing 12 are fixedly mounted in the sliding housing 7 .

[0026] In this embodiment, specifically: an external thread is provided on the bottom circumference of the sliding shell 7, a receiving cavity 700 for accommodating the float 8 is provided on the top of the sliding shell 7, and a threaded hole is provided inside the second gear 4 to cooperate with the external thread.

[0027] In this embodiment, specifically: three guide rods 14 are fixedly installed inside the sliding shell 7 and all pass through the second shell 12. Three key slots 1201 are opened at the bottom of the second shell 12. The second shell 12 is located inside the top of the first shell 11.

[0028] In this embodiment, specifically: a limiting plate 15 is provided on the circumferential side of the first shell 11, the upper surface of the limiting plate 15 is in contact with the lower surface of the second gear 4, and a connecting strip 16 fixedly connected to the motor 3 is fixedly installed on one side of the first shell 11.
