Description

[Technical Field]

[0001] This utility model relates to the field of cup pump technology, and in particular to a cup pump with good stability. [Background Technology]

[0002] Foam machines mix liquid and gas in a gas-liquid mixing chamber, allowing the detergent to be sprayed directly as foam without requiring users to manually rub the product repeatedly, thus providing a better user experience.

[0003] Existing foam pumps often use a cup pump to extract detergent and water, such as the novel electric foam pump disclosed in Chinese Utility Model Patent Application No. CN202311309121.X. However, due to the poor working stability of the cup holder in existing cup pumps, when extracting highly viscous detergents such as facial cleanser, the movement trajectory of the cup holder is prone to deviation. That is, when extracting viscous detergents with high resistance, the cup holder tends to deviate from its original movement trajectory and shift towards the direction of less resistance, making it difficult for the cup pump to accurately extract the required detergent. In view of the above-mentioned problems, the inventors of this case conducted in-depth research on this issue, resulting in this application. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a stable cup pump, which solves the problem that the cup holder of the existing cup pump is prone to deviating from the original movement trajectory and shifting in the direction of less resistance, thus making it difficult to accurately extract the required washing liquid.

[0005] This utility model is implemented as follows: a stable cup pump includes a housing, a cup disposed inside the housing, a cup holder disposed outside the housing, and a drive device for driving the cup holder to work. The bottom of the cup passes through the housing and is connected to the cup holder. A positioning mechanism is provided between the cup holder and the bottom of the housing to prevent the cup holder from shifting during operation.

[0006] Furthermore, the positioning mechanism includes a positioning pin located at the top of the leather cup holder and a positioning pin hole located at the bottom of the housing. The free end of the positioning pin extends into the positioning pin hole, and the outer diameter of the positioning pin is smaller than the diameter of the positioning pin hole.

[0007] Furthermore, the driving device includes a power component, an eccentric block, and an eccentric shaft. The eccentric block is connected to the output end of the power component, and the eccentric shaft is connected between the leather cup holder and the eccentric block.

[0008] Furthermore, the eccentric shaft has an extension that extends to the top of the leather cup holder, and the extension serves as a positioning pin.

[0009] Furthermore, the bottom of the housing is provided with a positioning seat, and a positioning pin hole is formed at the bottom of the positioning seat.

[0010] Furthermore, the positioning pin hole is an inverted conical hole that gradually increases in size from top to bottom.

[0011] Furthermore, the positioning mechanism includes a positioning pin hole at the top of the leather cup holder and a positioning pin at the bottom of the housing. The free end of the positioning pin extends into the positioning pin hole, and the outer diameter of the positioning pin is smaller than the diameter of the positioning pin hole.

[0012] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: by setting a positioning mechanism between the bottom of the leather cup holder and the shell, the leather cup holder can be positioned during the specific working process, ensuring that when the leather cup holder drives the leather cup to draw out high-viscosity washing liquid such as facial cleanser, the leather cup holder will not deviate from the original movement trajectory and shift to the direction with less resistance, thereby ensuring that the leather cup pump can draw out the required washing liquid more accurately during the working process.

Detailed Implementation Methods

[0027] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0029] Please see Figures 1 to 6 As shown, this utility model discloses a stable cup pump 100. The cup pump 100 includes a housing 1, a cup 2 disposed inside the housing 1, a cup holder 3 disposed outside the housing 1, and a drive device 4 that drives the cup holder 3 to work. The bottom of the cup 2 passes through the housing 1 and is connected to the cup holder 3, so that the drive device 4 can drive the cup holder 3 to move the cup 2, thereby enabling the belt 2 to extract liquids and gases. A positioning mechanism is provided between the cup holder 3 and the bottom of the housing 1 to prevent the cup holder 3 from shifting during operation.

[0030] This utility model provides a positioning mechanism between the bottom of the leather cup holder 3 and the housing 1, which allows the leather cup holder 3 to be positioned during operation. This ensures that when the leather cup holder 3 drives the leather cup 2 to extract high-viscosity detergents such as facial cleanser, the leather cup holder 3 will not deviate from its original trajectory and shift towards the direction with less resistance. This ensures that the leather cup pump 100 can extract the required detergent more accurately during operation.

[0031] As a first specific embodiment of this utility model, the positioning mechanism includes a positioning pin 51 located on the top of the leather cup holder 3 and a positioning pin hole 52 located on the bottom of the housing 1. The free end of the positioning pin 51 extends into the positioning pin hole 52, and the outer diameter of the positioning pin 51 is smaller than the diameter of the positioning pin hole 52. In this way, the leather cup holder 3 can be positioned by the cooperation of the positioning pin 51 and the positioning pin hole 52, and the leather cup holder 3 can drive the leather cup 2 to extract liquids and gases.

[0032] In the first specific embodiment of this utility model, the driving device 4 includes a power component 41, an eccentric block 42, and an eccentric shaft 43. The eccentric block 42 is connected to the output end of the power component 41; the eccentric shaft 43 is connected between the leather cup holder 3 and the eccentric block 42. During operation, the power component 41 outputs power to drive the eccentric block 42 to rotate. During the rotation of the eccentric block 42, it drives the eccentric shaft 43 to rotate eccentrically. During the eccentric rotation of the eccentric shaft 43, it drives the leather cup holder 3 to swing, thereby enabling the leather cup holder 3 to drive the leather cup 2 to extract liquids or gases.

[0033] In a first embodiment of this utility model, the eccentric shaft 43 has an extension section 431 extending to the top of the leather cup holder 3, and the extension section 431 serves as a positioning pin 51, that is, the upper end of the eccentric shaft 43 is directly used as a positioning pin 51. Of course, this utility model is not limited to this. In specific implementations, a positioning pin can also be additionally provided on the top of the leather cup holder 3, without extending the upper end of the eccentric shaft 43 to the top of the leather cup holder 3.

[0034] In a first embodiment of this utility model, a positioning seat 11 is provided at the bottom of the housing 1, and a positioning pin hole 52 is formed at the bottom of the positioning seat 11. In a specific implementation of this utility model, the positioning seat 11 is integrally formed at the bottom of the housing 1, which makes manufacturing more convenient and ensures that the positioning seat 11 can be reliably combined with the housing 1.

[0035] In the first specific embodiment of this utility model, the positioning pin hole 52 is an inverted conical hole that gradually increases in size from top to bottom, so that the positioning pin hole 52 can reliably position the positioning pin 51, and the positioning pin 51 can rotate better and drive the leather cup holder 3 to swing.

[0036] As a second specific embodiment of this utility model, the difference from the first specific embodiment is that: the positioning mechanism includes a positioning pin hole at the top of the leather cup holder 3 and a positioning pin at the bottom of the housing 1. The free end of the positioning pin extends into the positioning pin hole, and the outer diameter of the positioning pin is smaller than the diameter of the positioning pin hole. This can also achieve positioning of the leather cup holder 3, so that the leather cup holder 3 will not deviate from the original movement trajectory and shift in the direction of less resistance.

[0037] Finally, it should be noted that the difference between the present invention's cup pump 100 and existing cup pumps is that a positioning mechanism is provided between the cup holder 3 and the bottom of the housing 1 to prevent the cup holder 3 from shifting during operation. The other structures are the same as those of existing cup pumps and belong to the prior art. Therefore, the other structures of the cup pump 100 will not be described in detail here.

[0038] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
