Description

Technical Field

[0001] The present invention relates to a faucet assembly and a faucet for preventing freezing and cracking. Background Art

[0002] In cold winters, the temperature in the northern regions of China often drops below freezing point, resulting in frequent occurrences of frozen faucets. The freezing and damage of faucets lead to water leakage, causing a large amount of property losses and sometimes even posing risks to personal safety.

[0003] Chinese Patent Invention CN201110073428.5 discloses a faucet valve core, which includes a flow control valve plate and a temperature control valve plate. A water transmission component is provided between the flow control valve plate and the temperature control valve plate. It is characterized in that a mutually adapted shaft tube and a shaft tube cavity are respectively provided on the flow control valve plate attachment of the water transmission component and the fixed valve plate base. Corresponding cold and hot water through holes are provided on the walls of the shaft tube and the shaft tube cavity to form a three-dimensional surface sealing fit. The flow control valve plate attachment and the fixed valve plate base are made of materials with telescopic properties. The flow control valve plate attachment and the fixed valve plate base are made of materials with telescopic properties, so that the water passage from the flow control valve plate to the fixed valve plate has an anti-freezing function. The anti-freezing effect of this kind of faucet valve core is poor and its applicability is poor. In the valve core with a large water flow, the deformation amount of the material with telescopic properties is limited and it cannot prevent freezing. In addition, the flow control valve plate attachment and the fixed valve plate base made of telescopic materials will lead to a poor sealing effect between the two.

[0004] Chinese Patent Invention CN201721865636.8 discloses an improved anti-freezing washbasin faucet, which includes a metal faucet housing, a switch valve core and an integrated plastic valve core. The metal faucet housing is cast from zinc alloy and includes a metal faucet housing, an integrated plastic valve core, metal particles with rubber coating, a spring and a magnet. A lock hole is also provided on the inner middle side wall of the metal faucet housing. A positioning hole corresponding to the metal faucet housing is also provided on the outer side of the middle part of the integrated plastic valve core. A spring and a magnet are sequentially provided inside the positioning hole, and one end of the magnet extends into the lock hole inside the metal faucet housing and locks. The metal particles with rubber coating are mainly formed by integrally casting a metal ball and a 0.7-mm rubber layer. The gap between the integrated plastic valve core and the metal faucet housing is filled with metal particles with rubber coating. The cost of this kind of faucet is relatively high and a large amount of metal particles with rubber coating is required. Moreover, when water accidentally enters the inside of the metal faucet housing, the faucet may still freeze and crack when the water freezes. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a faucet assembly and a faucet for preventing freezing and cracking with good anti-freezing effect and low cost.

[0027] The present invention also provides a faucet, including: the above-mentioned faucet assembly for preventing freezing.

[0028] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0029] The faucet assembly includes a housing, a valve core, a valve seat body, an elastic member, and a guiding connection column. The valve core is arranged inside the housing, the valve seat body is movably arranged inside the housing, the guiding connection column connects the valve seat body and is guidingly connected to the housing, the elastic member is biased between the housing and the valve seat body, and the guiding connection column and the valve seat body are provided with a water inlet channel and a water outlet channel that can communicate with the valve core. The faucet assembly includes a use state and a frozen state. When in the use state, the elastic member biases the valve seat body so that the valve seat body presses against and connects to the valve core. When in the frozen state, the water in the water inlet channel, the water outlet channel, the valve seat body or the valve core freezes and expands to drive the valve seat body away from the valve core, and the elastic member accumulates a restoring force. In the use state, the faucet assembly can be used normally. When in the frozen state, the faucet assembly is affected by the external temperature, the water in the water inlet channel, the water outlet channel, the valve seat body or the valve core freezes and expands, and the water between the valve core and the valve seat body freezes and expands to drive the valve seat body away from the valve core. When the external temperature rises, the ice in the water inlet channel, the water outlet channel, the valve seat body or the valve core thaws into water, and the elastic member drives the valve seat body to press against and connect to the valve core, and the faucet assembly automatically returns to the use state without additional settings, with low cost and good anti-freezing effect;

[0030] The guiding connection column is guidingly connected to the housing to guide the movement of the valve seat body, thereby enhancing the anti-freezing effect of the faucet assembly. Description of the Drawings

[0034] The following further describes the present invention in conjunction with the drawings and specific embodiments.

[0035] Refer to Figures 1-3, a faucet assembly 100 for preventing freezing and cracking. The faucet assembly 100 is adapted to be connected to a faucet. The faucet assembly 100 includes a housing 10, a valve core 20, a valve seat body 30, an elastic member 40, and a guiding connection column 50. The housing 10 has a cylindrical barrel-like structure and has an open end 11 at one end. The housing 10 includes a bottom wall 12 and a surrounding wall 13 connecting the bottom wall 12. The top of the surrounding wall 13 defines the first end 14 of the housing 10 (i.e., the open end 11 of the housing 10), and the bottom wall 12 defines the second end 15 of the housing 10. The surrounding wall 13 and the bottom wall 12 surround and define an installation space 16. The valve core 20, the valve seat body 30, and the elastic member 40 are respectively inserted into the installation space 16 from the first end 14 of the housing 10. The faucet assembly 100 further includes a gland 60 connected to the first end 14 of the housing 10. The inner wall of the surrounding wall 13 includes an internal thread, and the gland 60 includes an external thread. The gland 60 is threadedly connected to the surrounding wall 13. The gland 60 further includes an annular stop wall 61 extending radially inward. The annular stop wall 61 defines a through hole 62. The valve shaft 21 of the valve core 20 extends out of the through hole 62. The annular stop wall 61 presses against the valve core 20. The gland 60 is used to close the first end 14 of the housing 10, which will be described in detail below.

[0036] The structure of the housing 10 can be cylindrical or other shapes adapted to the valve core 20, and is not limited thereto. For example, when the valve core 20 is square, the structure of the housing 10 can also be square, or the inner peripheral wall of the housing 10 is square and the outer peripheral wall is still cylindrical, and is not limited thereto.

[0037] The surrounding wall 13 of the housing 10 further includes an annular protrusion 17 disposed near the first end 14 of the housing 10. The annular protrusion 17 is used to connect and position to a corresponding structure inside the faucet. For example, the faucet includes a faucet housing, and the faucet housing is provided with an annular step corresponding to the annular protrusion 17. When the housing 10 is installed on the faucet, the annular protrusion 17 correspondingly abuts against the annular step.

[0038] The valve core 20 is arranged in the installation space 16 of the housing 10 and abuts against the gland 60. The valve seat body 30 is movably arranged in the installation space 16 of the housing 10. The valve seat body 30 can slide along the axial direction of the housing 10. The elastic member 40 is biased between the housing 10 and the valve seat body 30 so as to press the valve seat body 30 against the valve core 20. The valve core 20 is pressed and fixed between the gland 60 and the valve seat body 30. During normal use, the position of the valve core 20 does not change. In this embodiment, the first end 14 and the second end 15 of the housing 10 are arranged at intervals along the sliding direction of the valve seat body 30. The valve core 20 is arranged and connected to the first end 14 of the housing 10. The guiding connecting column 50 is guided to slide on the second end 15 of the housing 10. The elastic member 40 is biased between the second end 15 of the housing 10 and the valve seat body 30.

[0039] The shape of the valve seat body 30 corresponds to and fits the shape of the surrounding wall 13 so that the valve seat body 30 can slide in the installation space 16. In this embodiment, the valve seat body 30 is cylindrical and includes a first connecting surface 31 connected to the valve core 20. Referring to the figure, the first connecting surface 31 is the upper end surface of the valve seat body 30. The valve seat body 30 further includes a second connecting surface 32 connected to the guiding connecting column 50. The second connecting surface 32 is the lower end surface of the valve seat body 30. A through channel 33 extends through between the first connecting surface 31 and the second connecting surface 32. One end of the guiding connecting column 50 is connected to the second connecting surface 32, and the other end extends along the sliding direction of the valve seat body 30, passes through the second end 15 of the housing 10 and is guidingly connected (i.e., slidably connected) to the second end 15 of the housing 10. The guiding connecting column 50 is connected to the channel of the valve seat body 30. The guiding connecting column 50 further extends a connecting channel 51 corresponding to the through channel 33. One through channel 33 is correspondingly connected to one connecting channel 51 to define a water inlet channel 70 or a water outlet channel 80. The water inlet channel 70 and the water outlet channel 80 can communicate with the valve core 20. In this embodiment, the faucet assembly 100 includes two water inlet channels 70 and one water outlet channel 80. The two water inlet channels 70 are respectively connected to cold water and hot water and are connected to the valve core 20. The valve core 20 is controlled by the valve shaft 21 to output mixed water, and the mixed water flows out through the water outlet channel 80. In some simple replacements, the number of the water inlet channels 70 can also be one, for example, only connected to cold water; the number of the water outlet channels 80 can also be two, for example, the valve core 20 is of a two-in-two-out structure.

[0040] In this embodiment, one end of the guiding connecting column 50 is provided with a thread and is threadedly connected to the second connecting surface 32 of the valve seat body 30. The other end of the guiding connecting column 50 is used to connect to an inlet pipe or an outlet pipe.

[0041] The number of the guiding connection columns 50 may be one, and both the water outlet channel 80 and the water inlet channel 70 extend within one guiding connection column 50. Alternatively, the number of the guiding connection columns 50 may also be arranged according to the numbers of the water inlet channel 70 and the water outlet channel 80. For example, when the total number of the water inlet channel 70 and the water outlet channel 80 is two, the number of the guiding connection columns 50 is also two. In this embodiment, three guiding connection columns 50 are provided. The faucet assembly 100 includes two water inlet channels 70 and one water outlet channel 80, and the water inlet channel 70 and the water outlet channel 80 respectively extend and are arranged within the guiding connection columns 50. When at least two guiding connection columns 50 are provided, the effect of preventing the valve seat body 30 from rotating can also be achieved.

[0042] The elastic member 40 includes springs 41 respectively sleeved outside the guiding connection columns 50. The first end of the spring 41 abuts against the housing 10, and the second end of the spring 41 abuts against the valve seat body 30. The first end of the spring 41 abuts against the bottom wall 12 of the housing 10, and the second end of the spring 41 abuts against the valve seat body 30. When the valve seat body 30 slides, the spring 41 is compressed and stores elastic force. In this embodiment, each guiding connection column 50 is sleeved with a spring 41. In some simple replacements, only some of the guiding connection columns 50 may be sleeved with springs 41.

[0043] In this embodiment, the second end 15 (i.e., the bottom wall 12) of the housing 10 is provided with guiding holes corresponding to the guiding connection columns 50, and the guiding connection columns 50 respectively guide and slide on the guiding holes.

[0044] The faucet assembly 100 includes a use state and a freezing state; when in the use state, the elastic member 40 biases the valve core 20 seat so that the valve seat body 30 presses against and connects to the valve core 20. Specifically, the first end of the spring 41 abuts against the bottom wall 12 of the housing 10, and the second end abuts against the valve seat body 30 and drives the valve seat body 30 to press against and connect to the valve core 20. At this time, the lower end of the valve core 20 is pressed against by the first connection surface 31 of the valve seat body 30, and the upper end of the valve core 20 is limited by the annular retaining wall 61 of the gland 60. The valve core 20 connects the water inlet passage 70 and the water outlet passage 80. At this time, the faucet assembly 100 is in normal use; when in the freezing state, the faucet assembly 100 is affected by the external temperature, and the water in the water inlet passage 70, the water outlet passage 80, the valve seat body 30 or the valve core 20 freezes and expands. The water between the valve core 20 and the valve seat body 30 freezes and expands to drive the valve seat body 30 away from (i.e., slide away from) the valve core 20. At this time, the valve seat body 30 slides towards the bottom wall 12 of the housing 10, and the guiding connection column 50 guides and slides in the guiding hole. In this embodiment, the guiding connection column 50 extends along the sliding direction of the valve seat body 30 and can guide and connect to the housing 10 along this sliding direction. The elastic member 40 stores a restoring force, that is, the spring 41 is compressed to store elastic force. When the external temperature rises, the ice in the water inlet passage 70, the water outlet passage 80, the valve seat body 30 or the valve core 20 thaws into water. At this time, the elastic force stored by the spring 41 is released, the valve seat body 30 presses against and connects to the valve core 20, and the faucet assembly 100 returns to the use state.

[0045] In some simple replacements, the faucet assembly 100, which is suitable for connecting to the valve core 20 of the faucet, includes a valve seat body 30, an elastic member 40, and a guiding connection column 50. The guiding connection column 50 connects the valve seat body 30, the elastic member 40 biases the valve seat body 30, and the guiding connection column 50 and the valve seat body 30 are provided with a water inlet passage 70 and a water outlet passage 80 that can communicate with the valve core 20. The faucet assembly 100 includes a use state and a freezing state. When in the use state, the elastic member 40 biases the valve core 20 seat so that the valve seat body 30 presses against and connects to the valve core 20. When in the freezing state, the water in the water inlet passage 70, the water outlet passage 80, the valve seat body 30 or the valve core 20 freezes and expands to drive the valve seat body 30 away from the valve core 20, and the elastic member 40 stores a restoring force.

[0046] The faucet assembly 100 may not be provided with the housing 10, that is, the function of the housing 10 can be provided by the faucet. The faucet assembly 100 is suitable for connecting to the valve core 20 of the faucet.

[0047] As described above, it is only the preferred specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantial changes to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
