Description

Technical Field

[0001] The utility model relates to the field of automatic water inlet, in particular to an automatic water inlet device for a constant temperature and humidity chamber. Background Art

[0002] A constant temperature and humidity chamber regulates its internal temperature through a heating and cooling system. The heating system typically uses an electric heater. When the chamber temperature falls below the set point, the control system activates a heating element, which generates heat and raises the chamber temperature. The cooling system typically uses a compressor, similar to the refrigeration principle of a conventional refrigerator. The compressor compresses the refrigerant into a high-temperature, high-pressure gas. This gas then passes through a condenser, dissipating heat and transforming it into a liquid. The gas then passes through an expansion valve, reducing its pressure before entering the evaporator. In the evaporator, the refrigerant rapidly vaporizes, absorbing a significant amount of heat and lowering the chamber temperature. Precisely controlling the operation of the heating and cooling systems maintains the chamber temperature at the set constant level.

[0003] When the water level in the water tank drops during automatic water inflow, the float drops, driving the valve open via a connecting rod, allowing water to enter the water tank. When the water level rises to a certain height, the float rises, closing the valve and stopping the water inflow. This method only controls the water inflow, but not the amount of water inflow, which can lead to insufficient or excessive water flow during constant humidity and temperature control.

[0004] Therefore, we make improvements to this and propose an automatic water inlet device for a constant temperature and humidity chamber. Utility Model Content

[0005] The purpose of the utility model is to solve the problem of controlling the water intake during the water intake process.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model provides an automatic water inlet device for a constant temperature and humidity chamber to solve the above-mentioned problem.

[0007] The utility model is specifically as follows:

[0008] It includes a water tank, the top of which is fixedly connected to a spring, the lower end of the spring is fixedly connected to a limit block, the lower surface of the limit block is fixedly connected to a movable rod, the lower end of the movable rod is fixedly connected to a float valve, the upper surface of the float valve has a plurality of water inlets in a circular array, any of the water inlets is fixedly connected to a bellows, the upper end of the bellows is connected to a water pipe, and the other end of the water pipe is connected to the water tank.

[0009] As an optimal technical solution of the present invention, the lower surface of the movable rod is slidably connected to a limit ring, the limit ring is located between the float valve and the limit block, and the diameter of the limit block is smaller than the diameter of the limit ring, and the outer surface of the limit ring is fixedly connected to a connecting rod.

[0010] As a preferred technical solution of the present invention, the end of the connecting rod away from the limiting ring is fixedly connected with a slider, and the slider is slidably connected to the water tank away from the surface of the connecting rod.

[0011] As a preferred technical solution of the present invention, a threaded rod is fixedly connected to the upper surface of the sliding block, and the threaded rod passes through the water tank and is fixedly connected to a transmission gear at the upper end.

[0012] As a preferred technical solution of the present invention, the tooth root of the transmission gear is engaged with a rack, the middle part of the rack is engaged with an output gear, and the movable shaft of the output gear is fixedly connected to a reciprocating motor.

[0013] As an optimal technical solution of the present invention, the lower surface of the water storage tank is connected to a water inlet pipe, a three-way valve is provided on the outer surface of the water inlet pipe, the lower surface of the water storage tank is fixedly connected to a constant humidity box, constant temperature boxes are fixedly connected on both sides of the constant humidity box, and a support plate is fixedly connected to the lower surface of the constant humidity box.

[0014] As a preferred technical solution of the present invention, the water delivery pipe is U-shaped, and the length of the portion connected to the water tank end is always longer than the portion connected to the bellows.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. During the water inflow process, the water level inside the water tank continues to rise, driving the float valve up during the rising process. When the float valve rises to the limit ring, the float valve cannot continue to rise. At this time, the rising water level enters the float valve along the water inlet on the float valve until the float valve is filled with water. At this time, because the water supply pipe is U-shaped and the length of the part connected to the water tank end is always longer than the part connected to the bellows, according to the siphon principle, the water inside the float valve enters the water tank along the water supply pipe, thereby achieving the effect of automatic water inflow;

[0017] 2. When the control slider slides up and down, the reciprocating motor can be turned on. The reciprocating motor drives the output gear to rotate, which in turn drives the rack to transmit the power. The rack drives the transmission gear to rotate during the transmission process. The rotation of the transmission gear will drive the threaded rod to rotate. When the threaded rod rotates, it drives the slider to slide up. Similarly, when the reciprocating motor is rotated in the opposite direction, the threaded rod rotates in the opposite direction, driving the slider to slide down, thereby adjusting the height of the connecting rod to adjust the water inlet volume.

[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] As mentioned in the background technology, there is a problem of controlling the water intake during the water intake process.

[0031] In order to solve this technical problem, the utility model provides an automatic water inlet device for a constant temperature and humidity chamber (602), which is used to control the water inlet amount during the water inlet process.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] An automatic water inlet device for a constant temperature and humidity chamber includes a water tank 1. A spring 101 is fixedly connected to the top of the water tank 1. The lower end of the spring 101 is fixedly connected to a limit block 102. A movable rod 103 is fixedly connected to the lower surface of the limit block 102. The lower end of the movable rod 103 is fixedly connected to a float valve 104. The upper surface of the float valve 104 has a plurality of water inlets 105 in a circular array. A bellows 106 is fixedly connected to any water inlet 105. The upper end of the bellows 106 is connected to a water pipe 107. The other end of the water pipe 107 is connected to a water tank 108. The water pipe 107 is U-shaped, and the length of the portion connected to the water tank 108 is always longer than the portion connected to the bellows 106.

[0036] During the water inlet process, the water level inside the water tank 1 continues to rise, driving the float valve 104 to rise during the rising process. When the float valve 104 rises to the limit ring 2, the float valve 104 cannot continue to rise. At this time, the rising water level enters the float valve 104 along the water inlet 105 on the float valve 104 until the float valve 104 is filled with water. At this time, since the water supply pipe 107 is U-shaped and the length of the connection part with the water tank 108 end is always longer than the connection part with the bellows 106, according to the siphon principle, the water inside the float valve 104 enters the water tank 108 along the water supply pipe 107, thereby achieving the effect of automatic water inlet. When the water level inside the water tank 1 drops, the spring 101 squeezes the movable rod 103 and the float valve 104 downward due to the elastic action to reset them.

[0037] The lower surface of the movable rod 103 is slidably connected to the limit ring 2, which is located between the float valve 104 and the limit block 102. The diameter of the limit block 102 is smaller than that of the limit ring 2. The outer surface of the limit ring 2 is fixedly connected to the connecting rod 201.

[0038] The limit ring 2 slidably connected to the lower surface of the movable rod 103 is used to limit the movable rod 103 to prevent the movable rod 103 from shifting due to the movement of the float valve 104 during the up and down movement. The diameter of the limit block 102 is smaller than the diameter of the limit ring 2 to prevent the movable rod 103 from detaching from the limit ring 2. The connecting rod 201 fixedly connected to the outer surface of the limit ring 2 is used to control the limit ring 2 up and down.

[0039] The end of the connecting rod 201 away from the retaining ring 2 is fixedly connected to a slider 3. The surface of the slider 3 away from the connecting rod 201 is slidably connected to the water tank 1. A threaded rod 4 is fixedly connected to the upper surface of the slider 3. The threaded rod 4 extends through the water tank 1 and is fixedly connected to the upper end of the transmission gear 401. The roots of the transmission gear 401 mesh with a rack 5. The middle of the rack 5 meshes with an output gear 501. The movable shaft of the output gear 501 is fixedly connected to a reciprocating motor 502.

[0040] When the control slider 3 slides up and down, the reciprocating motor 502 can be turned on, and the reciprocating motor 502 drives the output gear 501 to rotate, thereby driving the rack 5 to transmit the power. The rack 5 drives the transmission gear 401 to rotate during the transmission process, and the rotation of the transmission gear 401 drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, it drives the slider 3 to slide up. Similarly, the reciprocating motor 502 is rotated in the opposite direction, and the threaded rod 4 rotates in the opposite direction, driving the slider 3 to slide down, thereby realizing the adjustment of the height of the connecting rod 201 to adjust different water inflow amounts.

[0041] The lower surface of the water storage tank 1 is connected to the water inlet pipe 6, and a three-way valve 601 is provided on the outer surface of the water inlet pipe 6. The lower surface of the water storage tank 1 is fixedly connected to a constant humidity box 602, and constant temperature boxes 603 are fixedly connected on both sides of the constant humidity box 602. The lower surface of the constant humidity box 602 is fixedly connected to a support plate 604.

[0042] The water inlet pipe 6 connected to the lower surface of the water tank 1 is used to transport water from the outside to the inside of the water tank 1 for water intake. Generally, the water inlet pipe 6 is directly connected to the tap water pipe. The three-way valve 601 set on the outer surface of the water inlet pipe 6 is used to control the water intake into the water tank 1. The constant humidity box 602 fixedly connected to the lower surface of the water tank 1 and the constant temperature box 603 fixedly connected on both sides of the constant humidity box 602 are used for constant temperature and humidity operation. The support plate 604 fixedly connected to the lower surface of the constant humidity box 602 is used to support the constant humidity box 602.

[0043] The use process of the automatic water inlet device of the constant temperature and humidity chamber provided by the utility model is as follows:

[0044] During the water inlet process, the water level inside the water storage tank 1 continues to rise, and the rising process drives the float valve 104 to rise. When the float valve 104 rises to the limit ring 2, the float valve 104 can no longer rise. At this time, the rising water level enters the float valve 104 along the water inlet 105 on the float valve 104 until the float valve 104 is filled with water. At this time, since the water supply pipe 107 is U-shaped and the length of the connection part with the water storage tank 108 end is always longer than the connection part with the bellows 106, according to the siphon principle, the water inside the float valve 104 enters the water storage tank 108 along the water supply pipe 107, thereby achieving the effect of automatic water inlet;

[0045] When the control slider 3 slides up and down, the reciprocating motor 502 can be turned on, and the reciprocating motor 502 drives the output gear 501 to rotate, thereby driving the rack 5 to transmit the power. The rack 5 drives the transmission gear 401 to rotate during the transmission process, and the rotation of the transmission gear 401 drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, it drives the slider 3 to slide up. Similarly, the reciprocating motor 502 is rotated in the opposite direction, and the threaded rod 4 rotates in the opposite direction, driving the slider 3 to slide down, thereby realizing the adjustment of the height of the connecting rod 201 to adjust different water inflow amounts.
