The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

Fig. 1-6 show a squeeze liquid dispenser according to a preferred embodiment of the present invention, comprising a housing 1 and a ball 2, wherein the housing 1 has a receiving chamber 11, the receiving chamber 11 is used for receiving a liquid, and part or all of the wall of the housing 1 surrounding the receiving chamber 11 is made of a soft material. The housing 1 is provided with a support groove 1311 (see fig. 5) inside thereof, the ball 2 is accommodated in the support groove 1311 and can roll relative to the support groove 1311, a liquid passage 12 penetrating the support groove 1311 and the accommodation chamber 11 is provided in the housing 1, a liquid outlet hole 1321 is provided in a housing wall of the housing 1, and the ball 2 is fitted in the liquid outlet hole 1321 (i.e., a part of the ball 2 is fitted in the liquid outlet hole 1321).

In use, since part or all of the housing walls of the accommodating chamber 11 are made of soft materials, the accommodating chamber 11 can be extruded to change in volume, so that the liquid in the accommodating chamber 11 enters the supporting groove 1311 along the liquid channel 12 and flows to the liquid outlet hole 1321 along the surface wall of the ball 2; moreover, when in use, the balls 2 are mainly rubbed by hands to roll the balls 2, so that the liquid squeezed into the supporting grooves 1311 flows to the liquid outlet holes 1321 along with the rotation of the balls 2, and the liquid is conveniently obtained by a user. In addition, as the amount of the liquid attached to the surface wall of the ball 2 is small, the phenomenon of liquid accumulation can not occur, so that the liquid at each part of the hand can be adhered with uniform liquid by repeatedly rubbing the ball 2 by the hand, thereby being convenient for fully utilizing the liquid or cleaning the liquid (such as hand washing liquid) from the hand.

In addition, it should be noted here that when liquid is needed or perhaps needed, the hand can frictionally roll the ball 2, and at the same time, the housing 1 can be pressed, but the accommodating chamber 11 can be deformed, i.e. the liquid can be obtained by one hand. The manual liquid pump of the present invention provides another inventive concept with respect to the prior art, and it can make the liquid obtained by the human hand uniformly stick to the human hand (particularly, the suitably viscous liquid) with respect to the squeeze pump of the prior art, improving the efficiency of fully utilizing the liquid or the efficiency of washing the liquid.

Among them, the known soft materials are various, but in this embodiment, a soft rubber material with elasticity, such as rubber, is preferably selected to ensure that the casing 1 can automatically recover after being pressed.

In this embodiment, in comparison with the case 1 manufactured by integral molding, the arrangement and installation of the internal structure of the case 1 are facilitated. Preferably, the housing 1 includes an upper case 13 and a lower case 14, and the upper case 13 is covered over the lower case 14. The upper shell 13 is made of hard materials, and the lower shell 14 is made of soft materials. The accommodating cavity 11 is arranged on the lower shell 14, and the supporting groove 1311 is arranged on the upper shell 13; and the liquid passage 12 is provided in the upper case 13. It will be appreciated that by making the upper housing 13 provided with the support groove 1311 of a hard material, a smooth support of the ball 2 by the support groove 1311 can be ensured, and the ball 2 can be rotated more easily. In addition, since the lower case 14 is made of soft material, the lower case 14 is deformed by pressing the upper case 13, and the process of pressing the case 1 is more convenient. Among them, hard materials are various, such as hard rubber materials, metal materials, wood materials, etc., and can be used according to actual demands.

The upper case 13 and the lower case 14 may be connected by welding, bonding, or clamping. For convenience of processing and manufacturing, the lower case 14 preferably forms a supporting edge 141 by protruding from inside to outside in the radial direction of the opening at the position of the opening of the accommodating chamber 11, and the upper case 13 is provided with an annular groove 1312 at the bottom thereof. The support edge 141 corresponds to the position of the groove 1312, and the support edge 141 is adapted to be embedded in the groove 1312. It will be appreciated that the shape of the support edge 141 may match the shape of the groove 1312, or the support edge 141 may be a sheet-like structure that fits tightly into the groove 1312. In this way, since the lower case 14 is made of soft material, a seal can be formed between the support edge 141 and the groove 1312, thereby preventing liquid from leaking from the accommodating chamber 11.

In order to reliably seal the support edge 141 within the groove 1312, liquid is further prevented from leaking out of the receiving chamber 11 along the groove 1312. More preferably, the squeeze liquid dispenser further includes a snap ring 3, the snap ring 3 being located directly below the support rim 141, the snap ring 3 engaging the groove 1312 and allowing the support rim 141 to be clamped within the groove 1312.

Preferably, the upper case 13 is provided with a liquid inlet hole 1313, the liquid inlet hole 1313 is communicated with the accommodating cavity 11, and the liquid inlet hole 1313 is used for supplying liquid into the accommodating cavity 11, so that the liquid does not need to be supplied along the liquid outlet hole 1321. A first sealing plug 1314 is removably attached to the inlet 1313; so that the liquid inlet 1313 can be conveniently opened or closed.

Preferably, the upper case 13 includes an upper cover 132 and a lower cover 131, the lower cover 131 is located between the upper cover 132 and the lower case 14, the groove 1312 is provided at the lower cover 131, and the lower cover 131 covers the opening of the accommodating chamber 11. The upper cover 132 covers the lower cover 131 to form an installation cavity 15, and the liquid outlet hole 1321 is formed in the lower cover 131; a first sealing plug 1314 is located within the mounting cavity 15; after the upper cover 132 is closed to the lower cover 131, the support groove 1311 is also closed by the upper cover 132, thereby preventing the inflow of liquid into the installation chamber 15. This arrangement ensures that the first sealing plug 1314 is in a concealed position and does not slide out of the housing 1. In addition to this arrangement, the upper cover 132 may form a plurality of spaces when closing the lower cover 131, that is, a plurality of reinforcing ribs may be provided between the upper cover 132 and the lower cover 131 to separate the spaces. The upper case 13 of this embodiment is simple and convenient to manufacture.

Preferably, the squeeze liquid dispenser further comprises a second sealing plug 4, a transmission rod 5 and a catch 6. The second sealing plug 4 is fixedly arranged in the shell 1 and is positioned outside the accommodating cavity 11, the second sealing plug 4 is provided with a blind hole 41, the blind hole 41 is sleeved with one end of the transmission rod 5, the shell 1 is further provided with a third through hole 1322 on the shell wall thereof, and the other end of the transmission rod 5 penetrates out of the shell 1 along the third through hole 1322 and is connected with the buckle 6. The transmission rod 5 is used for pressing the second sealing plug 4 and elastically deforming and elongating the second sealing plug 4 to block the liquid passage 12. The second sealing plug 4 is pressed by the transmission rod 5 to seal the liquid channel 12, so that the containing cavity 11 is thoroughly sealed when the liquid is not used, and the phenomenon that the liquid in the containing cavity 11 is polluted due to free movement of gas is prevented. And can not leak liquid when being carried.

The first sealing plug 1314 and the second sealing plug 4 may be made of conventional sealing materials, such as rubber, soft plastic, and the like.

Preferably, the wall of the housing 1 is notched at the position of the third through hole 1322 to form a first supporting plane 1323 and a second supporting plane 1324, and the third through hole 1322 is located in the first supporting plane 1323. The clasp 6 is provided with a third supporting plane 61 (see fig. 6) and a fourth curved arc surface 62 (see fig. 6) connected to each other. The buckle 6 is pivotally connected to the transmission rod 5, and the buckle 6 can rotate relative to the transmission rod 5 to enable the third supporting plane 61 to be attached to the first supporting plane 1323 or the second supporting plane 1324, so that the transmission rod 5 moves along the length direction of the transmission rod, and the second sealing plug 4 is elastically deformed to block the liquid channel 12 or open the liquid channel 12. The fourth curved arcuate surface 62 is configured to tangentially contact the second support plane 1324. It can be understood that, since the first supporting plane 1323, the second supporting plane 1324 and the third supporting plane 61 are all planar structures, the planes are not easy to loose from each other under the pretightening force of the driving rod 5 after the planes are abutted, so that the state of the second sealing plug 4 for blocking the liquid channel 12 or opening the liquid channel 12 is in a controllable state, i.e. is controlled by the buckle 6. In addition, since the fourth curved arc surface 62 is in tangential contact with the second supporting plane 1324, a relative rotation process of the fourth curved arc surface 62 and the second supporting plane 1324 is relatively easy.

Preferably, the transmission rod 5 comprises a cylindrical head 51, a limiting block 52 and a hinging rod 53 which are fixedly connected in sequence, the blind hole 41 is sleeved with the cylindrical head 51, the shell 1 is provided with a limiting plate 1315 (see fig. 1 or fig. 6), the limiting plate 1315 is positioned between the limiting block 52 and the buckle 6, and the hinging rod 53 extends out of the shell 1 along a third through hole 1322 and is pivotally connected with the buckle 6; the stopper plate 1315 serves to restrict the stopper 52 to the inside of the housing 1. It will be appreciated that the travel limit of the stop block 52 by the stop plate 1315 prevents the movable lever from being disengaged from the connection housing 1. Moreover, the limiting plate 1315 provides a certain extrusion force to the limiting block 52, so that the buckle 6 receives a certain pretightening force, and the third supporting plane 61 is more stable when being abutted against the first supporting plane 1323.

Preferably, a plurality of supporting grooves 1311 are formed, and each supporting groove 1311 accommodates one ball 2. By the arrangement, the liquid acquisition amount of the human hand can be increased, and the liquid can be kept to be uniformly adhered to the human hand, so that time is saved.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
