Abstract
The utility model discloses a waterproof electric heater, which comprises a metal shell and a heating element in a cavity of the shell. The two sides of the heating element are respectively provided with a linear conductor. The heating element and the linear conductor are sleeved in a protection tube. Two partitions are sleeved outside the protection tube at the two sides of the heating element, between both which a heating area is formed. The two sides of the protection tube are sealed and provided with a rubber sleeve. The protection tube is fixed in the cavity of the metal shell due to the support of a supporting board at two sides. The cavity between the partition 4 and the supporting board 6 forms a cooling area. The joint between the linear conduction and the external lead is sealed in the rubber sleeve. The electric heater is locally sealed, which has the advantages of simple structure and water prevention. The heating element can directly send the heat quantity out with high heat energy availability and good heating effect. The peripheral air flows to help the heating element to radiate and prolong the useful life. The utility model is widely applied to various electric heaters.
Description
Technical field
The utility model relates to a kind of electric heater, especially a kind ofly can be arranged on outdoor waterproof electric heater.
Background technology
The electric heater kind that is suitable for outdoor application in the market is few, because this electric heater is outdoor application, therefore must solve the problem of rainy day waterproof.Existing this type of waterproof electric heater normally adopts the mode of integral sealing to reach good waterproof effect on the market, promptly the opening end integral body at metal shell is provided with the glass capsulation cover, this class electric heater is arranged in the housing of sealing owing to heater, the long-time interior temperature of housing of using continues to raise, heat resistance to glass material requires very high, and this cloche also can block heater when realizing water-tight heat outwards distributes, not only influence heating effect, also can influence heater service life because of the operating ambient temperature of heater is too high, simultaneously, the glass case temperature is too high overheatedly also the situation that glass bursts may to occur, and has potential safety hazard.Along with gradually changing of people life style, outdoor electric heater is more and more universal, and the defective of this series products also becomes and becomes increasingly conspicuous, and remains further to be improved.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple in structure, waterproof and good, the safe in utilization electric heater of heating effect.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of waterproof electric heater, comprise the heater in metal shell and the housing cavity volume, it is characterized in that: described heater both sides respectively are provided with one section linear conductor, described heater and linear conductor all are sleeved in the pillar, the pillar of described heater both sides is set with dividing plate outward, and the cavity between two dividing plates forms the hot zone; Described pillar both side ends sealing is provided with rubber sleeve, described pillar is supported and fixed in the cavity volume of metal shell by the gripper shoe that both sides are provided with, cavity between described dividing plate and the gripper shoe forms the cooling zone, and the joint of described linear conductor and outer lead is enclosed in the rubber sleeve.
As optimal way of the present utility model, described rubber sleeve is stairstepping, is fixed on the gripper shoe by the installation sheet that is sleeved on the ladder place.
The beneficial effects of the utility model are: because the sealing of pillar both ends is provided with rubber sleeve, heater in the pillar and linear conductor are isolated from the outside, thoroughly changed the waterproof construction of existing outdoor electric heater, become integral sealing into partially sealed, both simple in structure, can reach the waterproof requirement of electric heater again; The pillar of heater both sides is set with dividing plate outward, cavity between two dividing plates forms the hot zone, dividing plate can reflect and isolate the heat that the hot zone produces, linear conductor does not generate heat, and the zone between dividing plate and gripper shoe, so promptly form a cooling zone, make rubber sleeve place, pillar both ends temperature be unlikely to rise to too high because of the heating of heater; Heater is arranged in the nonocclusive metal shell cavity volume, can be directly to extraneous distribute heat, and heat energy utilization rate height, heating effect is good, and airflow on every side, also helps the heat radiation of heater, increases the service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is that the part of Fig. 1 splits structural representation;
Fig. 3 is a fractionation structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of waterproof electric heater comprises the heater 2 in metal shell 1 and the housing cavity volume, and heater 2 both sides respectively are provided with one section linear conductor 3, heater 2 and linear conductor 3 all are sleeved in the pillar 5, and pillar 5 can adopt heat-resisting quartz ampoule or other materials; The cavity that the pillar of heater 2 both sides is set with outward between dividing plate 4, two dividing plates 4 forms the hot zone; The sealing of pillar 5 both side ends is provided with rubber sleeve 7, described pillar 5 is supported and fixed in the cavity volume of metal shell 1 by the gripper shoe 6 that both sides are provided with, cavity between described dividing plate 4 and the gripper shoe 6 forms the cooling zone, and described linear conductor 3 is enclosed in the rubber sleeve 7 with the joint of outer lead 12.
In the present embodiment, rubber sleeve 7 is stairstepping, is fixed on the gripper shoe 6 by the installation sheet 10 that is sleeved on ladder place 71; Certainly, the structure of rubber sleeve and fixed form also can adopt other forms.
The utility model is because the sealing of pillar 5 both ends is provided with rubber sleeve 7, heater in the pillar 2 and linear conductor 3 are isolated from the outside, have thoroughly changed the waterproof construction of existing outdoor electric heater, become integral sealing into partially sealed, both simple in structure, can reach the waterproof requirement of electric heater again; The pillar of heater 2 both sides is set with dividing plate 4 outward, cavity between two dividing plates 4 forms the hot zone, dividing plate 4 can reflect and isolate the heat that the hot zone produces, linear conductor 3 does not generate heat, and the zone between dividing plate 4 and gripper shoe 6, so just form a cooling zone, make pillar 5 both ends rubber sleeves 7 place's temperature be unlikely to too high; Heater is arranged in the nonocclusive metal shell cavity volume, can be directly to extraneous distribute heat, and heat energy utilization rate height, heating effect is good, and airflow on every side, also helps the heat radiation of heater, increases the service life.
